steroid enema for radiation proctitis

budesonide asthma steroid

Miami's independent source of local news and culture. Athletes and bodybuilders have been using steroids to increase muscle mass for a long time. Many men, particularly those who participate in sports or who are interested in bodybuilding, use steroids to achieve quick results. Many steroids are sold illegally and come with a slew of negative side effects. So, what are some other safe and legitimate alternatives to steroid abuse? Are you trying to bulk up or lose weight with a legal steroid? Researchers have recently created safe, and legal steroids that can be used daily with no negative side effects.

Steroid enema for radiation proctitis

However, such symptoms usually subside from 2 to 3 months after the end of RDT 8. Chronic radiation proctitis has several forms of clinical presentation, including mucous rectal discharge, diarrhea, urgency, pain, and bleeding. Recto-vaginal fistula, enteric fistula, cutaneous fistula, perforation, and rectal stenosis can rarely occur.

Histological alterations are mainly of a vascular nature, such as subintimal fibrosis and platelet thrombi in the arterioles of the submucosa with fibrosis of connective tissue 5. The development of RP is directly related to the dose of radiation, the irradiated volume, type of radiation exposure, dose fraction regimens, and the interval between sessions. Smith et al. Other factors predispose to RP, including previous abdomino-pelvic surgery, obesity, diabetes mellitus, hypertension, atherosclerosis, and simultaneous chemotherapy.

In , Bertuccelli et al. Endoscopic findings of RP are also variable. Since , when the first endoscopic findings were reported, there have been many attempts to establish a standardized endoscopic approach to its diagnosis Paleness, erythema, vascular abnormalities, and ulcerations are easily recognized alterations.

However, in order to correlate the clinical picture to endoscopic findings, Wachter et al. The prognosis of RP remains obscure. Gilinsky et al. Fifty percent presented slight to moderate symptoms with distinct endoscopic findings that resolved spontaneously in 2 years Nevertheless, 17 patients presented refractory symptoms.

Cho et al. Despite the fact that the incidence of RP tends to increase with time, RP still lacks research and attention. It should be noted that no consensus exists about its clinical and endoscopic evaluation and its natural history. Its behavior and prognosis are not completely known. Rectal bleeding due to RP usually represents a chronic condition, and anemia is a common finding; sometimes bleeding may be severe.

Several treatments for this presentation have been used, and as a result of its high recurrence rate, they were rarely utilized in a cyclic manner, which makes their evaluation difficult. We opted to review and analyze the results of conservative treatments of hemorrhagic CRP.

In , Goldstein et al. Subsequently, other studies were developed in an attempt to evaluate the use of steroids as a therapeutic alternative for RP, alone and also in combination with other modalities. In , Ben Bouali et al. In , Pajares et al. More recently, Triantafillidis et al. In a prospective randomized study, Kochhar et al.

Clinical improvement was appraised by a score based on the number of bowel movements, bleeding, and tenesmus. Therapy with sucralfate was more efficient, better tolerated, and cheaper. Another prospective randomized study in mice analyzed administration of 90 mg of hydrocortisone and showed endoscopic improvement and better tolerance when compared with betamethasone enemas Steroids have been used for many years in the treatment of RP despite the absence of larger and well-designed studies Moreover, steroids were not able to achieve sustained resolution of symptoms for patients with CRP.

Derivatives of 5-aminosalicylic acids 5ASA , also known as aminosalicylates, have been the object of research in treatment of RP since the studies of Menie et al. Aminosalicylates act in reducing the production of prostaglandins in the intestinal mucosa Goldstein et al. Bem Bouali et al. In , Ladas et al. On the other hand, in , Baum et al. Another study of 5 patients performed by Triantafillidis et al. We believe that multicenter prospective randomized studies of aminosalicylates are needed to confirm their role in the management of RP, but available evidence suggests that they are not effective.

Sucralfate is an aluminum salt that adheres to the mucous membrane, promoting the formation of a protective barrier that has been used for many years in the treatment of peptic ulcers. Its possible effectiveness for inflammatory proctitis and for colonic bleeding after endoscopic polypectomy is also under investigation. The cytoprotective action of sucralfate seems to be derived from the production of prostaglandins and promotion of epithelial cell proliferation.

In animal models of colitis in mice, rectal administration of sucralfate induced high E2-prostaglandin levels and increased cellularity of the colonic mucosa The best route for sucralfate administration remains controversial. In , Kochhar et al. A previous study by Henriksson et al.

Another study by Kochhar in demonstrated the superiority of topical sucralfate over steroid enemas administered in combination with sulfasalazine In , Stockdale and Biswas reported that administration of enemas containing 2 g of sucralfate in a patient with hemorrhagic RP resulted in long-term control of CRP as revealed from 4 years of follow-up Again in , Tada et al.

In , O'Brien et al. In this multicenter Australian study, 86 patients were randomized into 2 groups: 1 group received 3 g sucralfate enemas and the other group received a placebo. Enemas were administered once daily for a period of 2 weeks after RDT. Sucralfate enemas did not reduce symptoms associated with ARP and therefore should not be recommended in clinical practice. In , Sasai et al. They experienced significant improvement of rectal bleeding after daily administration of 4 g of sucralfate during 1 to 2 months The authors emphasized the advantages of oral sucralfate, which include good tolerance and few side effects associated with control of the symptoms for a long period.

More recently in , Kochhar et al. Stockdale and Biswas 28 studied 26 patients with hemorrhagic RP that were treated with 2 g sucralfate enemas twice daily. The patients were examined every 4 weeks in the first 16 weeks of treatment and after that at an interval of 8 to 12 weeks. Twenty patients had a significant reduction of bleeding in the first 4 weeks of treatment, as did another 4 patients after 16 weeks. At a mean of 45 weeks, 7 patients had some kind of symptomatic recurrence.

However, bleeding ceased soon after the sucralfate treatment was reintroduced. During the past few years, many studies have been performed on short-chain fatty acids SCFA so that knowledge regarding these substances has increased. Short-chain fatty acids are organic acids containing from 1 to 6 carbons that are a product of bacterial metabolism of some carbohydrates in the colon; they are the main source of energy for colonocytes. Butyrate is the most important SCFA and is preferentially metabolized by colonic mucosa when compared to propionate and acetate.

The effect of SCFA on rectal and colonic mucosa has been tested in patients with RP in an attempt to obtain healing of mucous lesions 33, In , Pinto et al. They demonstrated a beneficial effect from administration of 2 daily enemas with 60 mmol SCFA for 5 weeks in comparison with the administration of an isotonic solution.

There was a significant decrease of rectal bleeding with SCFA as well as an endoscopic improvement. In , Mamel et al. In , Al Sababagh et al. These results were not reproduced by Chen et al. More recently, Talley et al. They found no benefit from SCFA Regarding RP, the authors observed that studies showed early reduction of bleeding episodes, but SCFA had no influence in other symptoms such as chronic pain and tenesmus.

In spite of the great progress in the knowledge of the structure, metabolism, and action of SCFA, there is still need for additional data to confirm its effectiveness. Because of these conflicting data, there are no commercial preparations available for clinical use. The use of formalin in the management of RP emerged from its use in the treatment of bleeding tumors of the bladder and radiation cystitis 40,41, 2.

In , Rubinstein et al. The authors reported a year-old patient irradiated for bladder cancer who developed diffuse hemorrhagic RP. The patient underwent general anesthesia and the rectum was irrigated with two liters of 3.

An insufflated vesical probe was used in order to protect the sigmoid colon. The procedure was repeated after 2 weeks and after 3 months. Bleeding episodes immediately ceased and the patient was asymptomatic after 14 months. After these results, many authors initiated treatments of hemorrhagic CRP with formalin.

In , Seow-Choen et al. Patients underwent regional anesthesia and had their perianal skin protected to avoid direct contact with the formalin. Contact between the gauze and rectal mucosa was maintained until the bleeding stopped from 2 to 3 minutes. Bleeding ceased in 7 patients after a single session, while another patient needed an additional application. In , the same authors confirmed the effectiveness of direct application of formalin solution soaked gauze in 29 patients followed for 12 months In this study, rectal bleeding ceased right after application in 17 patients.

The 5 remaining patients obtained only partial improvement. The instillation technique proposed by Rubinstein et al. Treatment was well tolerated, and 11 patients needed 2 applications while other 3 patients needed 3 sessions. Saclarides et al. Four patients developed fissures in the anal verge and 1 developed tenesmus.

The technique of soaked gauze proposed by Seow-Choen was revised by 5 groups, with a total of 41 patients. Recently, in an Australian study, a combination of formalin and Nd:YAG neodymium yttrium-aluminum-garnet laser was used in 14 patients First, the patients underwent an endoscopic Nd:YAG laser procedure and then were treated with a formalin application as described by Seow-Choen.

A single session was enough for 9 patients, 2 sessions were necessary for3 patients, and 3 sessions forthe other 2 patients. Two patients required an operation to manage their symptoms. After these first published series with formalin as a therapeutic alternative for hemorrhagic RP, investigators have been trying to determine the best concentration and form of its application as well as its side effects. In low concentrations, formalin is not toxic. However, high concentrations can result in severe toxic effects.

Additionally, the nutritional state and smoking can alter blood levels of formalin. The patient developed chronic colitis that resolved after 2 months Evidence suggests that formalin is very effective in the treatment of hemorrhagic CRP, mainly in cases in which the 2 distal thirds of the rectum are affected. Other advantages of formalin application are low cost, low incidence of side effects, availability, and its easy manipulation. The author reported the success of this technique for the control of rectal hemorrhage after 4 applications in 1 patient in which he used 30 shots driven to the endoscopically identified vascular alterations The effectiveness of the Nd:YAG laser was confirmed by other authors in series with a total of 98 patients.

One of the most important was published by Viggiono et al. In , Swaroop et al. Initially, the patient should undergo a complete colonoscopy to determine the extent of the lesion. With an initial energy of 40 W and a maximum pulse duration of half a second, the laser is applied without direct contact to the mucosa, but with its tip less than 1 cm away from it. All visible lesions should be coagulated in the distal direction.

A white clot should be obtained as a final effect, avoiding cavities in the intestinal mucosa. Complications of Nd:YAG laser therapy include tenesmus, abdominal pain, rectal stenosis, prostatitis, and recto-vaginal fistula 55, Laser therapy for hemorrhagic CRP was supplanted by argon plasma coagulation APC because it is more readily available, cheaper, and requires fewer safety precautions, while still yielding excellent results.

Argon plasma coagulation is a diathermy method in which there is no direct contact between the electrode and the patient, and high frequency energy is applied to the tissue through the ionized argon. This technique is very suitable for coagulation of large bleeding surfaces and features the advantage of limited penetration 2 to 3 millimeters , minimizing the risks of perforation, stenosis, and fistulization. The char generated with APC promotes an interruption of the current passing through the tissue while Nd:laser continues to penetrate the tissue until it is switched off.

Since the first use of APC with a flexible endoscope described by Grund et al. Silva et al. Gas flow eliminates oxygen from the coagulation area, avoiding carbonization of the tissue and smoke production. Moreover, light produced by gas ionization promotes good visual control of the procedure.

In IMRT, radiation dose to the rectal wall is planned to be as low as possible, but radiation proctitis is still the most commonly encountered complication [ 8 — 11 ]. Radiation proctitis after IMRT seems to differ from that seen after whole-pelvic irradiation because this adverse event is a result of high-dose radiation to a very small area in the rectum.

To our knowledge, treatment of late rectal complication after IMRT has not been reported systematically. We have used steroid suppository or enema for pharmacotherapy, and APC as an endoscopic therapy. The purpose of this study was to evaluate the results of these treatments for hemorrhagic proctitis after IMRT for prostate cancer.

There were more high-risk patients and T3 patients in the linac group than in the tomotherapy group. Eighteen patients received antithrombotics before, during, and after IMRT for cardiovascular or cerebrovascular disease. The IMRT studies were performed prospectively with informed consent from all patients, but the present study evaluating rectal bleeding was a retrospective one.

This scoring system has been elaborated by ourselves for this study and is proposed to evaluate the grade of bleeding and efficacy of treatment. The Frequency Score was evaluated as follows: score 3, 3 or more episodes of bleeding per week; score 2, 0. The Amount Score was evaluated as follows: score 3, severe reddened toilet bowl ; score 2, moderate blood on stool surface ; and score 1, mild blood spot on paper.

All patients were immobilized in a supine position with a vacuum bag system for their whole body and CT scans were performed at a slice thickness of 3. Eclipse Version 6. The daily dose has been increased step by step from 2. The maximum dose to the rectum was set at The mean rectum volume was In 1 patient, a steroid suppository was used at first but treatment was later changed to an enema because of ineffectiveness.

Steroid enemas were more difficult to use for patients than steroid suppositories, and 2 patients could not undergo the enema successfully, so treatment was changed to a suppository immediately. Therefore, more recent patients were preferably treated with a steroid suppository.

The frequency of steroid administration was once or twice daily, depending on the severity. APC was used in 12 patients. All patients were treated without sedation. The forced mode was used at an argon flow rate of 1. The frequency of administration was up to 3 times, depending on the severity.

Paired t-tests were used to compare the changes after treatments. The response rate over time of respective strategies was calculated by the Kaplan-Meier method; patients who showed no response and moved to the next treatment were censored at that time. Log-rank tests were used to examine the other clinical variables including radiotherapy technique linac vs. The mean RBS changed from 3. Solid spots and error bars represent the mean and standard deviation of the data. The mean RBS improved significantly from 4.

There was no significant difference in response rate between steroid suppository and steroid enema groups. All but one patient had no complication with steroid therapy; one patient developed septic shock and died of multiple organ failure after treatment with steroid enema 0. No patient developed complications requiring treatment. Other factors were not associated with response after observation or steroid therapy. The development of adverse events related to radiation therapy depends on the dose and volume of normal tissues irradiated [ 13 ].

In most patients who had an endoscopic examination in the present study, a relatively small region of proctitis was detected, which was thought to represent adverse events of IMRT delivering a high dose to a limited area of the rectum. Hayashi et al. Patients observed for certain periods without treatment showed slight improvement of the bleeding score but this improvement was not statistically significant.

In other studies too, most of the patients showed improvement of endoscopic changes after prostate radiotherapy without treatment [ 15 , 16 ]. Obviously, when patients show severe bleeding leading to decrease of the hemoglobin level, immediate treatment with steroids or APC is recommended. The larger CTV for the SV due to the advanced T stage might have caused worse adverse events in the linac-group patients. We will further investigate the issue with more patients and longer follow-up periods.

Corticosteroids exert their anti-inflammatory effects in part by inhibiting histamine release and thereby stabilizing mast cells. It is anticipated that corticosteroids will help alleviate the symptoms of radiation proctitis. The efficacy of steroid enemas in the management of chronic radiation proctitis has yet to be proven, although slight symptomatic alleviation was proven in patients treated with steroid enemas and oral sulfasalazine in a small prospective double-blind study [ 17 , 18 ].

Intestinal bleeding after pelvic radiation therapy may be somewhat difficult to treat with steroid because radiation proctitis or colitis is more widespread. We used not only steroid enemas but also suppositories, in the expectation that the suppositories could be effective for small regions of proctitis after IMRT located just above the anal canal.

There have been some studies on pharmacotherapy of rectal bleeding [ 19 , 20 ], but no report exists regarding proctitis after IMRT, to the best of our knowledge. Therefore, steroid suppositories and enemas seem to be worthy of consideration when bleeding does not stop after observation. Earlier response was observed in patients with DM. We have no explanation for this observation and it might be related to the small number and biased selection of patients for the Kaplan-Meier method.

In one study, patients treated with antithrombotics more often developed grade 2 or 3 late rectal toxicity after external beam radiotherapy [ 23 ], but responses to treatments were not investigated. We could not find any differences in the response rates with or without antithrombotics. Each study used a different argon flow rate and voltage, and complications also differed, including severe ones such as rectal strictures and perforations.

Although there are no clear guidelines of precise APC settings for radiation proctitis, it was reported that the argon rate should be set at 1. Treatment is concentrated on the area of most prominent telangiectasia, leaving areas of untreated mucosa in between. Single or repeat pulses of less than 1 second are used, but care should be taken not to overlap or treat a particular area of rectal mucosa repeatedly; otherwise this increases the risk for mucosal ulceration that is characteristically slow to heal.

Chino et al. However, some patients who have severe proctitis, such as dilated veins associated with ulcers and erosions, showed serious complications. In these cases, APC is unlikely to be successful although it may ameliorate symptoms to some extent. We think that APC is effective especially in proctitis following IMRT since almost all of our patients had proctitis in so small areas of the rectum that complications could be reduced.

To manage rectal bleeding that does not disappear after adequate periods of observation, a steroid suppository or enema is expected to be effective and easy to use for patients. Even when patients have no response to pharmacotherapy, APC is effective and stops or decreases bleeding in a relatively short period.

Forty patients had received IMRT using a linear accelerator and 24 by tomotherapy. Their median age was 72 years. Depending on the severity, steroid suppositories or enemas were administered up to twice daily and Argon plasma coagulation APC was performed up to 3 times. Response to treatment was evaluated using the Rectal Bleeding Score RBS , which is the sum of Frequency Score graded from 1 to 3 by frequency of bleeding and Amount Score graded from 1 to 3 by amount of bleeding. Stoppage of bleeding over 3 months was scored as RBS 1.

Results: The median follow-up period for treatment of rectal bleeding was 35 months range, months. Grade of bleeding was 1 in 31 patients, 2 in 26, and 3 in 7. You could also ask your pharmacist for advice on other ways to help you remember to use this medicine. This is because they are applied directly into the bowel and the medicine gets to where it's needed without affecting the rest of your body. Sometimes budesonide can get through the lining of your bowel into your blood, meaning you are at higher risk of side effects.

However, this is more likely to happen if you use it for a long time. It is possible to have a serious allergic reaction anaphylaxis to budesonide. These are not all the side effects of budesonide. For a full list see the leaflet inside your medicines packet. You can report any suspected side effect to the UK safety scheme.

Budesonide rectal foam and enemas are not usually recommended when you're pregnant. This is because there's not enough information to know whether they're safe to use during pregnancy. However, your doctor may prescribe budesonide rectal foam or enemas if they think this is the best treatment for you. Speak to your doctor if you have questions about your medicine. It's generally OK to use budesonide rectal foam and enemas while breastfeeding.

However, you should always check with your doctor first. Small amounts of budesonide can get into breast milk. Your baby may need extra monitoring if you use higher doses or if you are using it for a long time. Some medicines and budesonide interfere with each other. This can increase your chance of getting side effects.

There's very little information about taking herbal remedies and supplements while taking or using budesonide. Ask a pharmacist for advice. Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.

Steroids closely copy the effects of natural hormones produced in your adrenal glands. The adrenal glands are above your kidneys. They work by calming down your immune system. This reduces inflammation in the lining of your bowel and bottom rectum and helps relieve symptoms like pain and bloody diarrhoea.

Your symptoms will usually start to improve within 1 or 2 weeks. It can take 2 to 4 weeks for the medicine to reach its full effect. Your doctor will tell you how long to use budesonide for. Occasionally they may want you to use it for longer, or give you a repeat prescription. Do not eat grapefruit or drink grapefruit juice while you're using budesonide. Grapefruit does not mix well with this medicine. However, if you have ulcerative colitis you may need to avoid certain foods to help your symptoms.

Read about living with ulcerative colitis for more advice. Budesonide does not affect any type of contraception, including the combined pill and emergency contraception. However, if you're having a flare-up of ulcerative colitis with diarrhoea, your body may not absorb oral contraceptive pills very well. Ask your doctor or a pharmacist about other contraception options.

Read more about what to do if you're on the pill and you're being sick or have diarrhoea. There is no clear evidence to suggest that using budesonide will reduce fertility in either men or women. However, speak to a pharmacist or your doctor if you're trying to get pregnant.

This medicine is not usually recommended during pregnancy. However, if budesonide affects your eyesight in any way, do not drive, cycle or use tools or machinery. The injected flu vaccine is generally safe to have because this is an "inactive" vaccine. When you are using budesonide, your immune system might not be strong enough to handle a live vaccine.

This could lead you to getting an infection. If you're on a high dose of steroids or need to take them for a long time, your pharmacist or doctor may give you a steroid treatment card. Carry this with you all the time. If you need any medical or dental treatment, show your blue steroid card to the doctor or dentist. The card, which is usually blue, is the size of a credit card and fits in your wallet or purse.

It tells you how to reduce the risks of steroid-related side effects. It also gives details of your doctor, your dose of budesonide and how long your treatment is expected to last.

Always follow your doctor's instructions when using your medicine. Budesonide rectal foam Budesonide foam comes in a can with single-use plastic tubes applicators. Try to use it at about the same time of day, either in the morning or in the evening before bed. How to use the foam First read the instruction leaflet. The pictures show you exactly how to use the foam.

Wash your hands before and after using the foam. Push a new applicator onto the nozzle. This nozzle sticks out beneath the dome at the top of the can. Shake the can for about 15 seconds. There is a rounded gap at the base of the dome. Twist the dome until the gap lines up with the nozzle. Put your finger on top of the dome and turn the can upside down. It's important to keep the can as straight vertical as possible. Stand with one leg raised on a chair — or lie down on your side if you prefer.

Gently put the tip of the applicator into your bottom as far as possible. Push the dome down. This fills the applicator with a dose of foam. Release the dome very slowly. Wait 10 to 15 seconds and then slowly remove the applicator from your bottom. Do not do this too quickly to prevent the foam coming out. Remove the applicator from the nozzle. Put it in the plastic bag provided and throw the bag away. Budesonide enemas This medicine comes as liquid and tablets that you mix together.

The usual dose is one enema every night. How to prepare the enema First read the instruction leaflet. Take a bottle of the liquid and unscrew the whole top section. Keep the nozzle and protective cap together. Do not separate them. Remove 1 tablet from the foil strip and drop it into the bottle of liquid. Replace the nozzle and protective cap and screw firmly back onto the bottle.

WHERE ARE ANABOLIC STEROIDS INJECTED

Pelvic radiation is administered either as neoadjuvant or adjuvant therapy. After pelvic irradiation, the rectum is the commonest site of injury within the gastrointestinal tract. The fixed anatomical position of the rectum in the pelvis and the close proximity to the prostate, cervix and uterus make the rectum especially vulnerable to secondary radiation injury resulting in proctitis [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ].

The anterior rectal wall is in close proximity to and partly in continuity with the therapeutic target organs prostate, uterus [ 17 , 18 ]. Although the development of late gastrointestinal toxicity following pelvic radiotherapy is not entirely dose related, there is a rapid rise in the number of rectal complications when the cumulative mean rectal dose and the cumulative maximum dose exceed 75 Gy, and there is also evidence that the incidence of severe complications rises sharply above a total dose of 80 Gy [ 19 , 20 , 21 ].

Treatment for prostate carcinoma typically receives 75 Gy over 7 to 8 weeks, and cervical carcinoma might receive 45 Gy of the typical external beam radiotherapy EBRT plus a variable dosing of brachytherapy [ 22 ]. It occurs within 1—6 weeks of radiation treatment and is generally self-limited with symptom resolution often within 3 months after the onset of therapy [ 2 , 4 , 6 , 8 , 12 , 23 , 24 , 25 ].

There is some evidence to suggest that moderate or severe chronic radiation proctitis is at least twice more likely to occur in those initially experiencing severe acute proctitis [ 22 , 26 ]. Chronic radiation proctitis occurs months to years after treatment with a large majority within 2 years post radiotherapy, and this entity is a troublesome complication in those undergoing pelvic irradiation for any cause.

The incidence of late complications is about 2. The development of postradiation rectal toxicity is not entirely dose, volume and fractionation schedule related. It also depends on a complex interaction of physical, patient-related and genetic factors, but these have been poorly characterized to date [ 7 ].

Many patients suffer progressive disease that may be life-long. Any part of the gastrointestinal tract may be affected by the radiation [ 4 ]. Radiotherapy induces long-term changes in bowel function as a result of progressive endothelial dysfunction, which includes ischemia and subsequent fibrosis.

The same processes may cause dysfunction in other pelvic organs; therefore, Andreyev et al. PRD currently affects as many each year as develop inflammatory bowel disease IBD has a spectrum of symptoms identical to IBD and shares some of its pathological features. During therapeutic irradiation of a pelvic malignancy, parts of distal small bowel, caecum, transverse and sigmoid colon and rectum are often also irradiated.

Additionally, the pancreas and proximal small bowel may also receive some irradiation if para-aortic nodes are treated. So, Andreyev et al. This is not further discussed here because they go beyond the scope of this chapter which focuses mainly on chronic radiation proctitis [ 27 , 34 , 35 , 36 ].

Radiation-induced bowel toxicity has been dominated by the application of scoring scales that are based on clinical symptoms [ 7 , 27 ]. Intensity of chronic radiation proctitis is also scored with regard to clinical symptoms. Numerous grading systems are used in the literature to assess rectal toxicity following radiotherapy. Refractory bleeding is a real challenge to clinicians.

The frequency of rectal bleeding after RT is said to occur in 29— Patients may present symptoms of obstructed defecation because of strictures accompanied with constipation, rectal pain, urgency and sometimes fecal incontinence. Fistulas into adjacent organs e. Because of the nature of radiation injury, the incidence of severe complications transfusion-dependent bleeding, fistula formation, rectal stricture and bowel obstruction, perforation, secondary malignancy increases with time.

Estimates of the significance of these severe consequences of radiotherapy have varied between 0. Late injury to the rectum usually occurs in the first 2—3 years after treatment and the incidence then plateaus [ 25 , 43 ]. Each patient who has undergone radiotherapy for pelvic malignancies and reports symptoms suggestive of radiation-induced proctitis should be suspected of this entity, even if irradiation was performed many years ago.

Endoscopy, in any case, is important to determine the extent and severity of chronic radiation proctopathy as well as to exclude other possible causes of inflammation or malignant disease [ 8 ]. Abnormal endoscopic findings after pelvic radiotherapy include congested mucosa, telangiectasia, erythema or pallor, ulceration, stricture, fistula and necrosis.

Fragile rectal mucosa is prone to bleeding. Telangiectasia of the rectal mucosa which are very frequent and a major cause of bleeding may resolve spontaneously after 3 years. However, the prevalence of telangiectases in unselected patients is unknown [ 8 , 18 , 29 , 31 , 32 , 43 ].

Endoscopic evaluation of acute radiation proctitis shows edematous, dusky red rectal mucosa, whereas endoscopy of chronic radiation proctitis shows mucosal atrophy, ectatic superficial capillaries, tortuous blood vessels, telangiectasias, variable stenosis, strictures and fistulas [ 6 ].

Characteristic endoscopic changes of rectal mucosal damage in the course of radiation proctitis are shown in Figure 1. Typical endoscopic appearance of rectal mucosal damage in the course of radiation proctitis—congested and friable mucosa, extensive rectal mucosal hypervascularity, tortuous blood vessels and telangiectases. It is also important to highlight that due to the possibility of initiating chronic, poorly healing wounds and the risk of possible complications of sepsis, fistula formation and also the increased risk of bleeding, biopsy of devitalized rectal tissues should be avoided as they do not contribute to the diagnosis of chronic radiation proctopathy.

Rectal biopsy is only justified if any malignancy is suspected or in a case of important therapeutic consequences [ 8 , 12 , 44 ]. Radiation-induced proctitis should be suspected in any patient after pelvic radiotherapy who presents the symptoms of this entity. Acute radiation proctitis may mimic allergic or eosinophilic colitis, but the history will allow accurate diagnosis.

However, endoscopy is essential to exclude other causes of acute or chronic proctitis such as infectious colitis, inflammatory bowel disease, diversion colitis, ischemic colitis, angiodysplasia, diverticular colitis and concomitant other malignancies [ 6 , 8 ]. Radiation-induced proctopathy is unlikely to find one treatment modality that works for all patients. Acute radiation-induced proctitis is managed conservatively and includes hydration, antidiarrheals and steroid or 5-aminosalicylate enemas [ 12 ].

Chronic radiation-induced proctitis can be managed conservatively anti-inflammatory agents, sucralfate, short-chain fatty acids, hyperbaric oxygen therapy, antioxidants and also includes ablation formalin enemas, radiofrequency ablation, YAG laser or argon plasma coagulation and surgery [ 12 ]. There was also a case report of successful treatment of a patient with severe refractory hemorrhagic radiation proctitis with low dose of oral thalidomide [ 6 , 45 ].

It is very important to realize, when considering invasive treatment that chronic radiation-induced proctitis can improve over time without any treatment [ 8 ]. The mechanism of anti-inflammatory action of 5-ASA is the inhibition of prostaglandin synthesis.

Steroids prednisone, betamethasone, hydrocortisone have multiple mechanisms of action that produce anti-inflammatory effects which extend from stabilization of lysosomes in neutrophils to prevent degranulation to upregulation of anti-inflammatory genes via binding to glucocorticoid receptors [ 12 ].

Steroids have been used to treat radiation proctitis both alone and in combination with other agents [ 28 ]. The addition of metronidazole to oral mesalazine and betamethasone enemas was associated with a reduction in rectal bleeding, diarrhea and ulcers [ 8 ]. Sucralfate 2—3 g of sucralfate in a 15—20 ml suspension, oral sucralfate, paste adheres to mucosal cells and stimulates epithelial healing and the formation of protective epithelial barrier while PPS a synthetic derivative of a glycosaminoglycan is thought to reduce epithelial permeability and prevent adherence similar to sucralfate.

Moreover, sucralfate has been found to induce a better clinical response than anti-inflammatories in patients with CRP. Based on a Cochrane review, sucralfate enemas were more effective than corticosteroid or mesalazine enemas [ 8 , 12 , 22 , 28 , 35 , 39 ]. A novel method of rectal administration of sucralfate via a low-volume sucralfate paste two sucralfate 1 g tablets mixed with 4.

PPS, a fibrinolytic, anti-inflammatory and mucoprotective agent, resolved symptoms in nine of thirteen patients with established chronic radiation proctitis [ 20 ]. Short-chain fatty acids are the main energy source for colonocytes and stimulate colonic mucosal proliferation. The most important product of SCFA is butyric acid. They also exert a vasodilatatory effect on the arteriole walls to improve blood flow.

SCFAs were found to accelerate the healing process, with a significant early reduction in bleeding episodes and endoscopic scores. One of two small randomized, placebo-controlled trials noted more rapid improvement in symptoms and endoscopic findings in a group of patients using a butyrate-containing SCFAs solution over a 5-week period compared with placebo controls [ 12 , 22 , 28 ]. Formalin application has been demonstrated to be generally effective and safe in hemorrhagic proctitis and, however, may cause complications such as chronic anorectal pain, fever, fecal incontinence, rectosigmoid necrosis with or without perforation, enteric fistula formation, anal and rectal strictures as well as pelvic sepsis.

Direct contact with formalin for 2—3 minutes via formalin solution installation through endoscope or Foley catheter or soaked gauze causes chemical cauterization of neovasculature [ 9 , 12 , 35 , 40 , 41 , 47 ]. As oxidative stress is thought to be an important factor in the development of chronic radiation proctitis, antioxidants have been used in an attempt to limit tissue damage. The use of vitamins E IU three times daily , C mg three times daily and A 10, IU twice daily for 90 days significantly reduced proctitis symptoms diarrhea, bleeding, urgency [ 8 , 12 , 48 ].

A variety of endoscopic coagulation devices e. There have been also reports on endoscopic balloon dilatation and stenting for radiation-induced rectal strictures [ 12 , 28 ]. Argon plasma coagulation APC — monopolar diathermy is used to ionize the argon gas which coagulates the telangiectatic vessels in a noncontact fashion 0. On the other hand, we have to realize severe complications that may happen after this procedure which is performed in chronically ischemic tissues deep ulceration, fistulation, rectal stenosis, rebound bleeding, long-term pain, perforation, rectovaginal fistula and even bowel explosions in inadequately prepared bowels.

The development of rectal ulcers after APC is thought to be a consequence of thermal injury. On the basis of anecdotal evidence, APC is commonly ineffective in patients with very heavy bleeding [ 8 , 12 , 15 , 20 , 25 , 31 , 35 , 47 , 49 ]. YAG laser coagulation has a similar benefit as APC with a limited depth of penetration and the possibility for precise application.

The major risk for laser coagulation is transmural necrosis, with perforation or stricture formation. Nevertheless, the laser is expensive and not widely available [ 8 , 12 , 20 , 31 ]. Endoscopic cryoablation cryospray ablation therapy involves noncontact application of liquid nitrogen or carbon dioxide gas to the tissue and offers superficial ablation of mucosa in patients with CRP.

Cryotherapy has been suggested as a safe and effective method for bleeding in CRP. Hou et al. Overall subjective clinical scores improved as determined by the Radiation Proctitis Severity Assessment Scale from Cryotherapy is novel and up to date, and there is very limited data [ 15 , 24 , 47 ].

HBOT involves patients breathing pure oxygen in a pressurized room or tube. Under these conditions, the lungs can gather more oxygen than at normal air pressure. The Frequency Score was evaluated as follows: score 3, 3 or more episodes of bleeding per week; score 2, 0. The Amount Score was evaluated as follows: score 3, severe reddened toilet bowl ; score 2, moderate blood on stool surface ; and score 1, mild blood spot on paper. All patients were immobilized in a supine position with a vacuum bag system for their whole body and CT scans were performed at a slice thickness of 3.

Eclipse Version 6. The daily dose has been increased step by step from 2. The maximum dose to the rectum was set at The mean rectum volume was In 1 patient, a steroid suppository was used at first but treatment was later changed to an enema because of ineffectiveness.

Steroid enemas were more difficult to use for patients than steroid suppositories, and 2 patients could not undergo the enema successfully, so treatment was changed to a suppository immediately. Therefore, more recent patients were preferably treated with a steroid suppository. The frequency of steroid administration was once or twice daily, depending on the severity. APC was used in 12 patients.

All patients were treated without sedation. The forced mode was used at an argon flow rate of 1. The frequency of administration was up to 3 times, depending on the severity. Paired t-tests were used to compare the changes after treatments. The response rate over time of respective strategies was calculated by the Kaplan-Meier method; patients who showed no response and moved to the next treatment were censored at that time. Log-rank tests were used to examine the other clinical variables including radiotherapy technique linac vs.

The mean RBS changed from 3. Solid spots and error bars represent the mean and standard deviation of the data. The mean RBS improved significantly from 4. There was no significant difference in response rate between steroid suppository and steroid enema groups. All but one patient had no complication with steroid therapy; one patient developed septic shock and died of multiple organ failure after treatment with steroid enema 0. No patient developed complications requiring treatment.

Other factors were not associated with response after observation or steroid therapy. The development of adverse events related to radiation therapy depends on the dose and volume of normal tissues irradiated [ 13 ].

In most patients who had an endoscopic examination in the present study, a relatively small region of proctitis was detected, which was thought to represent adverse events of IMRT delivering a high dose to a limited area of the rectum. Hayashi et al. Patients observed for certain periods without treatment showed slight improvement of the bleeding score but this improvement was not statistically significant.

In other studies too, most of the patients showed improvement of endoscopic changes after prostate radiotherapy without treatment [ 15 , 16 ]. Obviously, when patients show severe bleeding leading to decrease of the hemoglobin level, immediate treatment with steroids or APC is recommended. The larger CTV for the SV due to the advanced T stage might have caused worse adverse events in the linac-group patients. We will further investigate the issue with more patients and longer follow-up periods.

Corticosteroids exert their anti-inflammatory effects in part by inhibiting histamine release and thereby stabilizing mast cells. It is anticipated that corticosteroids will help alleviate the symptoms of radiation proctitis. The efficacy of steroid enemas in the management of chronic radiation proctitis has yet to be proven, although slight symptomatic alleviation was proven in patients treated with steroid enemas and oral sulfasalazine in a small prospective double-blind study [ 17 , 18 ].

Intestinal bleeding after pelvic radiation therapy may be somewhat difficult to treat with steroid because radiation proctitis or colitis is more widespread. We used not only steroid enemas but also suppositories, in the expectation that the suppositories could be effective for small regions of proctitis after IMRT located just above the anal canal.

There have been some studies on pharmacotherapy of rectal bleeding [ 19 , 20 ], but no report exists regarding proctitis after IMRT, to the best of our knowledge. Therefore, steroid suppositories and enemas seem to be worthy of consideration when bleeding does not stop after observation.

Earlier response was observed in patients with DM. We have no explanation for this observation and it might be related to the small number and biased selection of patients for the Kaplan-Meier method. In one study, patients treated with antithrombotics more often developed grade 2 or 3 late rectal toxicity after external beam radiotherapy [ 23 ], but responses to treatments were not investigated. We could not find any differences in the response rates with or without antithrombotics.

Each study used a different argon flow rate and voltage, and complications also differed, including severe ones such as rectal strictures and perforations. Although there are no clear guidelines of precise APC settings for radiation proctitis, it was reported that the argon rate should be set at 1. Treatment is concentrated on the area of most prominent telangiectasia, leaving areas of untreated mucosa in between. Single or repeat pulses of less than 1 second are used, but care should be taken not to overlap or treat a particular area of rectal mucosa repeatedly; otherwise this increases the risk for mucosal ulceration that is characteristically slow to heal.

Chino et al. However, some patients who have severe proctitis, such as dilated veins associated with ulcers and erosions, showed serious complications. In these cases, APC is unlikely to be successful although it may ameliorate symptoms to some extent. We think that APC is effective especially in proctitis following IMRT since almost all of our patients had proctitis in so small areas of the rectum that complications could be reduced.

To manage rectal bleeding that does not disappear after adequate periods of observation, a steroid suppository or enema is expected to be effective and easy to use for patients. Even when patients have no response to pharmacotherapy, APC is effective and stops or decreases bleeding in a relatively short period.

Abstract Background Radiation proctitis after intensity-modulated radiation therapy IMRT differs from that seen after pelvic irradiation in that this adverse event is a result of high-dose radiation to a very small area in the rectum.

Background Chronic rectal bleeding is one of the most common complications of radiation therapy for prostate cancer. Table 1 Patient characteristics. Open in a separate window. Intensity-modulated radiotherapy All patients were immobilized in a supine position with a vacuum bag system for their whole body and CT scans were performed at a slice thickness of 3. Figure 1.

Systematic review for non-surgical interventions for the management of late radiation proctitis. Br J Cancer. All corticosteroids increase calcium excretion. While on corticosteroid therapy patients should not be vaccinated against smallpox. Other immunization procedures should not be undertaken in patients who are on corticosteroids, especially on high dose, because of possible hazards of neurological complications and a lack of antibody response.

Persons who are on drugs which suppress the immune system are more susceptible to infections than healthy individuals. Chicken pox and measles, for example, can have a more serious or even fatal course in non-immune pediatric patients or adults on corticosteroids. In such pediatric patients or adults who have not had these diseases, particular care should be taken to avoid exposure.

How the dose, route and duration of corticosteroid administration affects the risk of developing a disseminated infection is not known. If exposed to chicken pox, prophylaxis with varicella zoster immune globulin VZIG may be indicated. If exposed to measles, prophylaxis with pooled intramuscular immunoglobulin IG may be indicated. If chicken pox develops, treatment with antiviral agents may be considered.

If corticosteroids are indicated in patients with latent tuberculosis or tuberculin reactivity, close observation is necessary as reactivation of the disease may occur. During prolonged corticosteroid therapy, these patients should receive chemoprophylaxis. Hydrocortisone Rectal Suspension, USP should be used with caution where there is a probability of impending perforation, abscess or other pyogenic infection; fresh intestinal anastomoses; obstruction; or extensive fistulas and sinus tracts.

Use with caution in presence of active or latent peptic ulcer; diverticulitis; renal insufficiency; hypertension; osteoporosis; and myasthenia gravis. Steroid therapy might impair prognosis in surgery by increasing the hazard of infection. If infection is suspected, appropriate antibiotic therapy must be administered, usually in larger than ordinary doses.

Drug-induced secondary adrenocortical insufficiency may occur with prolonged Hydrocortisone Rectal Suspension, USP therapy. This is minimized by gradual reduction of dosage. This type of relative insufficiency may persist for months after discontinuation of therapy; therefore, in any situation of stress occurring during that period, hormone therapy should be reinstituted.

There is an enhanced effect of corticosteroids on patients with hypothyroidism and in those with cirrhosis. Corticosteroid should be used cautiously in patients with ocular herpes simplex because of possible corneal perforation. The lowest possible dose of corticosteroid should be used to control the conditions under treatment, and when reduction in dosage is possible, the reduction should be gradual. Psychic derangement may appear when corticosteroids are used, ranging from euphoria, insomnia, mood swings, personality changes, and severe depression, to frank psychotic manifestations.

Also, existing emotional instability or psychotic tendencies may be aggravated by corticosteroids. Growth and development of pediatric patients on prolonged corticosteroid therapy should be carefully observed. Persons who are on immunosuppressant doses of corticosteroids should be warned to avoid exposure to chicken pox or measles. Patients should also be advised that if they are exposed, medical advice should be sought without delay.

Local pain or burning and rectal bleeding attributed to Hydrocortisone Rectal Suspension, USP have been reported rarely. Apparent exacerbations or sensitivity reactions also occur rarely. The following adverse reactions should be kept in mind whenever corticosteroids are given by rectal administration. Fluid and Electrolyte Disturbances: Sodium retention; fluid retention; congestive heart failure in susceptible patients; potassium loss; hypokalemic alkalosis; hypertension.

Musculoskeletal: Muscle weakness; steroid myopathy; loss of muscle mass; osteoporosis; vertebral compression fractures; asceptic necrosis of femoral and humeral heads; pathologic fracture of long bones. Gastrointestinal: Peptic ulcer with possible perforation and hemorrhage; pancreatitis; abdominal distention; ulcerative esophagitis. Dermatologic: Impaired wound healing; thin fragile skin; petechiae and ecchymoses; facial erythema; increased sweating; may suppress reactions to skin tests.

Neurological: Convulsions; increased intracranial pressure with papilledema pseudo-tumor cerebri usually after treatment; vertigo; headache. Endocrine : Menstrual irregularities; development of Cushingoid state; suppression of growth in pediatric patients; secondary adrenocortical and pituitary unresponsiveness, particularly in times of stress, as in trauma, surgery or illness, decreased carbohydrate tolerance; manifestations of latent diabetes requirements for insulin or oral hypoglycemic agents in diabetics.

Ophthalmic: Posterior subcapsular cataracts; increased intraocular pressure; glaucoma; exophthalmos. Metabolic: Negative nitrogen balance due to protein catabolism. The use of Hydrocortisone Rectal Suspension, USP hydrocortisone retention enema is predicated upon the concomitant use of modern supportive measures such as rational dietary control, sedatives, antidiarrheal agents, antibacterial therapy, blood replacement if necessary, etc.

The usual course of therapy is one Hydrocortisone Rectal Suspension, USP nightly for 21 days, or until the patient comes into remission both clinically and proctologically. Clinical symptoms usually subside promptly within 3 to 5 days. Improvement in the appearance of the mucosa, as seen by sigmoidoscopic examination, may lag somewhat behind clinical improvement.

Where the course of therapy extends beyond 21 days, Hydrocortisone Rectal Suspension, USP should be discontinued gradually by reducing administration to every other night for 2 or 3 weeks.
