Abstract
Synthetic glucocorticoids are widely used for their anti-inflammatory and immunosuppressive actions. A possible unwanted effect of glucocorticoid treatment is suppression of the hypothalamic-pituitary-adrenal axis, which can lead to adrenal insufficiency. Factors affecting the risk of glucocorticoid induced adrenal insufficiency (GI-AI) include the duration of glucocorticoid therapy, mode of administration, glucocorticoid dose and potency, concomitant drugs that interfere with glucocorticoid metabolism, and individual susceptibility. Patients with exogenous glucocorticoid use may develop features of Cushing's syndrome and, subsequently, glucocorticoid withdrawal syndrome when the treatment is tapered down. Symptoms of glucocorticoid withdrawal can overlap with those of the underlying disorder, as well as of GI-AI. A careful approach to the glucocorticoid taper and appropriate patient counseling are needed to assure a successful taper. Glucocorticoid therapy should not be completely stopped until recovery of adrenal function is achieved. In this review, we discuss the factors affecting the risk of GI-AI, propose a regimen for the glucocorticoid taper, and make suggestions for assessment of adrenal function recovery. We also describe current gaps in the management of patients with GI-AI and make suggestions for an approach to the glucocorticoid withdrawal syndrome, chronic management of glucocorticoid therapy, and education on GI-AI for patients and providers.

Abstract
The two main forms of intestinal bowel disease, namely ulcerative colitis and Crohn's disease, are not curable but can be controlled by various medical therapies. The Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD) has prepared clinical practice guidelines to help physicians prescribe corticosteroids and immunosuppressive drugs for these patients. The guidelines consider therapies that induce remission in patients with active disease as well as treatment regimens that maintain remission. These guidelines complement already existing guidelines from IG-IBD on the use of biological drugs in patients with inflammatory bowel diseases.

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. We evaluated the results of treatment for hemorrhagic proctitis after IMRT for prostate cancer. Methods Between November 2004 and February 2010, 403 patients with prostate cancer were treated with IMRT at 2 institutions. Among these patients, 64 patients who developed late rectal bleeding were evaluated. Forty patients had received IMRT using a linear accelerator and 24 by tomotherapy. Their median age was 72 years. Each patient was assessed clinically and/or endoscopically. 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, 12–69 months). Grade of bleeding was 1 in 31 patients, 2 in 26, and 3 in 7. Nineteen of 45 patients (42%) observed without treatment showed improvement and bleeding stopped in 17 (38%), although mean RBS did not change significantly. Eighteen of 29 patients (62%) treated with steroid suppositories or enemas showed improvement (mean RBS, from 4.1 ± 1.0 to 3.0 ± 1.8, p = 0.003) and bleeding stopped in 9 (31%). One patient treated with steroid enema 0.5-2 times a day for 12 months developed septic shock and died of multiple organ failure. All 12 patients treated with APC showed improvement (mean RBS, 4.7 ± 1.2 to 2.3 ± 1.4, p < 0.001) and bleeding stopped in 5 (42%). Conclusions After adequate periods of observation, steroid suppositories/enemas are expected to be effective. However, short duration of administration with appropriate dosage should be appropriate. Even when patients have no response to pharmacotherapy, APC is effective.

Abstract
BACKGROUND Topical beclomethasone diproprionate has shown efficacy in ulcerative colitis. AIM To assess, in a multicenter, randomized, double-blind study, the tolerability and safety of topical beclomethasone diproprionate (3mg) enema and foam versus mesalazine (2g) enema and foam in mild-moderate distal ulcerative colitis. PATIENTS In 15 referral gastrointestinal units, 99 patients with distal ulcerative colitis were enrolled. This number was lower than planned according to the statistical analysis, due to a low recruitment rate. METHODS Patients were randomly assigned to random preparations (beclomethasone diproprionate enema, beclomethasone diproprionate foam, mesalazine enema, mesalazine foam) once nightly for 8 weeks, with clinical and endoscopical assessment (Disease Activity Index score) at baseline (T0), 4 (T4) and 8 weeks (T8). Results were expressed as median and range (95% confidence interval). The efficacy was assessed by comparing the Disease Activity Index value at T4 and T8 by using the Student's t-test or the Wilcoxon-Mann-Whitney test. RESULTS Efficacy was comparable in the beclomethasone diproprionate or mesalazine groups at both T4 and T8 (response at T4: beclomethasone diproprionate 78% [95% confidence interval 0.6-0.8] versus mesalazine 79% [95% confidence interval 0.6-0.8]; T8: beclomethasone diproprionate 84% [95% confidence interval 0.7-0.9] versus mesalazine 90% [95% confidence interval 0.7-1.0]; p=n.s.; remission at T4: beclomethasone diproprionate 24% [95% confidence interval 0.1-0.3] versus mesalazine 28% [95% confidence interval 0.1-0.3]; remission at T8: beclomethasone diproprionate 36% [95% confidence interval 0.2-0.5] versus mesalazine 52% [95% confidence interval 0.3-0.6]; p=n.s.). The Disease Activity Index lowered at T4 and T8 versus T0 in the four groups (T4 versus T0: beclomethasone diproprionate foam Disease Activity Index 2 versus 6 p<0.0001; beclomethasone diproprionate enema 4 versus 6, mesalazine enema 3 versus 6, mesalazine foam 3.5 versus 7, p<0.001 for all three groups; T8 versus T0: p<0.01). The Disease Activity Index lowered at T8 versus T4 in the beclomethasone diproprionate enema and foam (Disease Activity Index: 2 versus 4 and 1 versus 4, respectively; p<0.05) and in the mesalazine enema (Disease Activity Index: 1.5, range 0-4 versus 3, range 0-12; p<0.01), but not in the mesalazine foam group (Disease Activity Index: 1, range 0-9 versus 3.5, range 0-8; p=n.s.). The safety profile was favourable for all groups. CONCLUSIONS Beclomethasone diproprionate and mesalazine enema and foam show a comparable tolerability and efficacy in mild active distal ulcerative colitis.

Abstract
AIM To assess safety and clinical efficacy of granulocyte and monocyte adsorptive apheresis for distal ulcerative colitis. METHODS Granulocyte and monocyte adsorptive apheresis therapy (five aphereses for 5 consecutive weeks) was performed for 30 consecutive patients with active distal ulcerative colitis. Patient compliance, adverse effects and clinical symptoms were regularly assessed. RESULTS Adverse effects were noted during nine (6%) apheresis sessions in eight patients; slight headache five, transient abdominal pain with tenesmus two, fever (38 degrees C) one and mild liver dysfunction one. None of these adverse effects was serious and all patients could complete five aphereses. Clinical symptoms (stool frequency and consistency, rectal bleeding, tenesmus and mucus in stools) significantly improved after the third apheresis. Clinical remission (normal stool frequency and no rectal bleeding) was achieved in 21 patients (70%) after five aphereses. The median Disease Activity Index score significantly decreased; from 6 [interquartile range (IQR): 4-7] to 2 (IQR: 1-3) (P < 0.0001). CONCLUSION In the treatment of active distal ulcerative colitis, granulocyte and monocyte adsorptive apheresis is safe and well-tolerated. Granulocyte and monocyte adsorptive apheresis had a beneficial effect on clinical remission and symptoms. However, randomized-controlled trials would be necessary to assess a definite efficacy of granulocyte and monocyte adsorptive apheresis.

Abstract
Ulcerative colitis and Crohn's disease are chronic gastrointestinal diseases that affect patients in the prime of their lives. Because inflammatory bowel disease (IBD) patients generally live a normal lifespan, chronic medical therapy for IBD must be tolerable, simple to adhere to, and have as few side effects as possible. This article discusses the impact of IBD on quality of life and stresses the importance of appropriate and individualized medical therapy. To help clinicians determine the efficacy of particular IBD medications, this article offers a brief, practical interpretation of clinical, endoscopic, and quality-of-life end points used in clinical trials. Finally, it provides a summary of the current accepted medical therapies for ulcerative colitis adn Crohn's disease and recommendations for using these medications in clinical practice.

Abstract
OBJECTIVES In patients with inflammatory bowel disease (IBD), little is known about the effect of long term corticosteroid therapy (CT) on the hypothalamic-pituitary-adrenal (HPA) axis function. Our aim was to assess HPA axis function in IBD, before the end of CT, during the tapering phase. METHODS HPA axis function was assessed with cortisol (ng/ml) measurement before (T0) (normal > 100) and 60 min (normal > 210) after 0.25 mg tetracosactide (Synacthen immédiat) injection (T60) in 55 consecutive cases of IBD attacks. Abnormal response was defined as a T60 <210. The attacks were separated into two groups according to the result of the Synacthen test (ST). RESULTS In all, 36 of 55 ST were abnormal. The time for recovery normal HPA axis function was 7.2+/-1.3 months. Duration of disease since onset, past history of surgical or immunosuppressive treatment, severity and extension of the attack, need for surgical or immunosuppressive treatment, total cumulative and mean daily corticosteroid dose, total duration of CT, and steroid dose at the time of ST were not significantly different in the two groups. In multivariate analysis a past history of CT was predictive of abnormal ST (OR = 8.4, 95% CI = 2.2-31.5, p = 0.0009). Among patients with a past history of CT, the time (months) elapsed between the last course of CT was significantly longer in those with normal ST than in those with abnormal ST (45.5+/-13.5 vs 15.4+/-6.0; p = 0.02), and in multivariate analysis a duration free of CT < 15 months was predictive of abnormal ST (OR = 15.00, CI = 1.23-183.00, p = 0.03). CONCLUSIONS In all, 65% of the ST were abnormal. These results suggest that ST should be performed before corticosteroid withdrawal, especially in patients with recent past history of CT.

Abstract
An intravenous infusion of cyclosporine A (CsA) shows clinical benefits in patients with steroid-resistant ulcerative colitis (UC). To clarify its mechanisms, we investigated the ability of CsA to inhibit the functions of neutrophils and T cells. The cytotoxic activity by mucosal T cells was analyzed by anti-CD3-triggered cytotoxicity after lamina propria mononuclear cells were cultured with recombinant interleukin (IL)-2. The chemotactic response, the generation of superoxide, and the production of chemokines, IL-8, and macrophage inflammatory protein-1alpha by neutrophils were examined using a multiple-well chamber assay, a chemiluminescence method, and an enzyme-linked immunosorbent assay (ELISA), respectively. Mucosal chemokine activity was determined by an ELISA using the organ culture supernatant of mucosal biopsy tissues. Pretreatment with CsA caused consistent inhibitions of cytotoxic activity by mucosal T cells and chemotactic migration, superoxide generation, and chemokine production by neutrophils mostly in a dose-dependent manner. In patients who received an intravenous infusion of CsA, mucosal chemokine activity decreased after therapy in parallel with decreases in the numbers of neutrophils and mononuclear cells in the biopsy tissues. These results suggest that suppressive effects of CsA on neutrophils and T cells may be related to therapeutic benefits in patients with steroid-resistant UC.

Abstract
Intestinal graft-versus-host disease (GVHD) can readily easily induce generalized metabolic disturbance that influences morbidity and mortality after allogeneic bone marrow transplantation. Although adding a new drug or increasing the doses of immunosuppressive agents will probably be effective for controlling intestinal GVHD, the systemic side effects of such therapy cannot be ignored. In this study, we used betamethasone retention enemas as a local treatment for eight patients with refractory and/or severe intestinal GVHD. Six of the eight patients showed improvement of diarrhea and/or abdominal pain, with a reduction in the stage of GVHD. When treatment with betamethasone enemas was continued for 10 to 27 days in the 6 responding patients, no severe toxicity was observed. One patient failed to respond to treatment and another could not tolerate the enemas. Despite some uncertainty regarding the indications and duration of treatment, betamethasone enemas seem to be a potential alternative method for the management of intestinal GVHD.

Abstract
BACKGROUND & AIMS Budesonide is a highly potent topical glucocorticosteroid that is characterized by low systemic availability as a result of high first-pass hepatic metabolism. The aim of this study was to evaluate the efficacy and safety of three doses of an enema preparation of budesonide in patients with active distal ulcerative colitis/proctitis. METHODS In a double-blind multicenter trial, 233 patients were randomized to receive either a placebo enema or budesonide enema at a dose of 0.5 mg/100 mL, 2.0 mg/100 mL, or 8.0 mg/100 mL. The primary efficacy variables were an improvement of sigmoidoscopic inflammation grade, total histopathology score, and remission rates. Effects on cortisol concentrations were also assessed. RESULTS After 6 weeks of treatment, there was significant improvement in sigmoidoscopy and histopathology scores in the budesonide 2.0-mg and 8.0-mg dose groups compared with placebo. Remission was achieved in 19% of patients in the 2.0-mg budesonide group (P </= 0.050) and 27% of patients in the 8.0-mg budesonide group (P </= 0.001) compared with 4% in the placebo group. More than 90% of all budesonide patients had a normal adrenocorticotropin (ACTH)-stimulated cortisol response at the last visit. The budesonide enemas were well tolerated. CONCLUSIONS Budesonide enema is both effective and safe for the treatment of active distal ulcerative colitis/proctitis. A dose of 2. 0 mg/100 mL budesonide is the lowest effective dose.

Abstract
AIM To compare beclomethasone dipropionate 3 mg/60 mL enema (BDP) and prednisolone sodium phosphate 30 mg/60 mL enema (PP) once daily in patients with active distal ulcerative colitis. METHODS One hundred and fifty-seven patients were enrolled in a multicentre, 4-week, randomized, double-blind trial. Patients were assessed at baseline, 2 and 4 weeks. RESULTS Both treatment groups showed statistically significant improvement of clinical activity after 2 and 4 weeks. Endoscopy and biopsy showed a reduction in the activity score at the end of the treatment period in both groups. No statistically significant difference was observed between the two treatment groups. After 4 weeks, 29% of patients in the BDP group and 25% in the PP group were considered to be in clinical remission; an improvement was observed in 40% of patients on BDP and in 47% on PP. Mean morning plasma cortisol levels showed a slight but significant reduction in the PP group, while the ACTH test showed that neither drug interfered with the hypothalamic-pituitary-adrenal (HPA) axis function. No significant changes were observed in the laboratory tests. Finally, there was a low incidence of adverse events in both groups. CONCLUSIONS It is concluded that, in the topical treatment of active distal ulcerative colitis, BDP 3 mg enemas are as efficacious as PP 30 mg enemas, without interference with the HPA axis.

Abstract
BACKGROUND Clear strategies to optimise the use of corticosteroids in ulcerative colitis are lacking. AIM A meta-analysis was undertaken to examine critically the role of rectal corticosteroids in the management of active distal ulcerative colitis. METHODS All reported randomised controlled trials were retrieved by searching the Medline and EMBASE databases and the bibliographies of relevant studies. Trials which met inclusion criteria were assessed for scientific rigour. Data were extracted by two independent observers according to predetermined criteria. RESULTS Of 83 trials retrieved, 33 met inclusion criteria. Pooled odds ratios (POR) showed conventional rectal corticosteroids and rectal budesonide to be clearly superior to placebo. In seven trials, rectal 5-aminosalicylic acid (5-ASA) was significantly better than conventional rectal corticosteroids for inducing remission of symptoms, endoscopy, and histology with POR of 2.42 (95% confidence interval (CI) 1.72-3.41), 1.89 (95% CI 1.29-2.76), and 2.03 (95% CI 1.28-3.20), respectively. Rectal budesonide was of comparable efficacy to conventional corticosteroids but produced less endogenous cortisol suppression. Side effects, although inconsistently reported, were generally minor. A cost comparison of rectal preparations showed 5-ASA to be less expensive than corticosteroids. CONCLUSIONS Rectal 5-ASA is superior to rectal corticosteroids in the management of distal ulcerative colitis.

Abstract
Topical therapy can be considered the standard treatment for distal ulcerative colitis. The group of drugs of first choice are the aminosalicylates which are effective in inducing remission in acute disease as well as in preventing relapse. Corticosteroids appear to be slightly less effective and have no proven benefit in maintenance therapy. With new topical steroids, such as budesonide, systemic effects can be minimized. The major role of corticosteroids is to complement aminosalicylates, when necessary. The new topical compounds appear to be especially valuable when there is a long-term requirement for corticosteroids. With the vast majority of patients obtaining remission with standard treatment, it is difficult to make the case for alternative substances. Short-chain fatty acids, local anaesthetics and bismuth compounds seem to be the most promising innovations in topical therapy although their equivalence or even superiority to mesalazine has not been established.

Abstract
BACKGROUND Budesonide is a new corticosteroid with high topical anti-inflammatory activity but little systemic effect. The aim of the present study was to compare the efficacy and safety of budesonide enema (2 mg/100 mL) and 5-ASA enema (mesalazine 1 g/100 mL) given for 4 weeks in the treatment of active distal ulcerative colitis and proctitis. METHODS Ninety-seven patients were studied in a multicentre single-blind randomized group-comparative trial. The primary efficacy variables were endoscopy and histopathology scores obtained at 0, 2 and 4 weeks. Clinical symptoms were the secondary efficacy variables. Haematology, chemistry and adverse events were the safety variables. RESULTS Budesonide and 5-ASA enemas both resulted in a significant improvement in endoscopy and histopathology scores but no difference could be demonstrated between the two treatment groups. There was also a significant improvement of symptoms (number of bowel movements per day, quality of stools, presence of blood and mucus, and state of well-being) within both groups but no difference between the two treatment groups. The clinical remission rate at 4 weeks was, however, 38% for patients treated with budesonide enema but 60% for those treated with 5-ASA enema (P = 0.03). No adverse events attributed to the study drugs were recorded in either of the groups. CONCLUSIONS Budesonide enema 2 mg/100 mL appears to be as efficient and well-tolerated as 5-ASA enema in the treatment of active distal ulcerative colitis and proctitis.

Abstract
BACKGROUND Corticosteroid enemas represent effective treatment for ulcerative proctitis, but absorption into the systemic circulation may have undesirable metabolic consequences. Prednisolone metasulphobenzoate, a lipophobic corticosteroid derivative, is designed to be absorbed poorly through the recto-sigmoid mucosa, but the effects of foam enema preparations upon the hypothalamo-pituitary-adrenal axis have not been examined. METHODS Nine patients suffering from active ulcerative proctitis underwent four weeks of therapy with prednisolone metasulphobenzoate foam enemas. The hypothalamo-pituitary-adrenal axis, defined using the modified single-dose metyrapone test, glucose homeostasis and lipid profiles were studied before and after treatment. RESULTS The hypothalamo-pituitary-adrenal axis was significantly depressed after the treatment period; mean stimulated plasma cortisol concentration fell from 384 +/- 244 (s.d.) to 288 +/- 252 nmol/L, P < 0.02; stimulated mean plasma 11-deoxycortisol concentration fell from 677 +/- 333 to 407 +/- 326 nmol/L, P < 0.01. Mean fasting plasma glucose, insulin, C-peptide, fructosamine and triglyceride concentration were unchanged, whilst the mean serum cholesterol concentrations rose from 5.6 +/- 1.1 to 6.0 +/- 1.2 mmol/L (not significant). CONCLUSION Prednisolone metasulphobenzoate foam enemas have significant systemic and endocrine metabolic effects, which could assume importance with long-term therapy.

Abstract
Rectal treatment with enemas, foams, and suppositories is the most efficient method of delivering an adequate quantity of locally active drugs to the distal colon. In a pilot study carried out by colonoscopy in four patients, it was observed that 4 g 5-ASA in 20 ml foam spread up or beyond the splenic flexure and more extensively than 2 g 5-ASA in 10 ml foam. Therefore we have undertaken a study in order to compare by scintigraphy the colonic distribution of 4 g 5-ASA foam versus 4 g 5-ASA in 100 ml liquid enemas in 10 patients with ulcerative colitis using a crossover randomized design. Both preparations were labeled with 100 MBq [99mTc]sulfur colloid before administration. Anterior scans were taken at intervals for 4 hr. Activity, expressed as a percentage of total radioactivity, was measured in the rectum, sigmoid, descending, transverse, and ascending colon. Six patients had the same extent of spread with the two formulations; in three patients with foam and in one patient with enema a greater spread was observed. The foam reached the upper limit of disease in all cases, while enema failed in two cases. The maximum spread with foam was observed within 30 min in nine of 10 patients compared with seven of 10 after enema. Compared to enema, foam distributes more uniformly and seems to persist longer in the descending and sigmoid colon. The 5-ASA colonic foam shows some more favorable characteristics than enema for the local treatment of left-sided ulcerative colitis.

Abstract
Corticosteroid or 5-aminosalicylic acid enemas are the treatment of choice for distal ulcerative colitis but up to one third of patients may be unresponsive. As an alternative therapy might be advantageous, the efficacy of six weeks' treatment with 2 g 4-aminosalicylic acid (4-ASA) (n = 24) and 20 mg prednisolone enemas (n = 21) were compared in a double blind, randomised trial in patients with acute distal (less than 30 cm from the anus) ulcerative colitis. Baseline demography and clinical severity were similar in both groups. Five of 24 patients receiving 4-ASA and 4 of 21 receiving prednisolone did not complete the trial because of deteriorating symptoms, failure to improve, or side effects. At the time of leaving the trial, 24 hour stool frequency, the presence of blood in the stools, and histological and sigmoidoscopic appearances were similar in both groups. Symptomatic improvement occurred in 17 of 24 patients receiving 4-ASA compared with 11 of 21 receiving prednisolone (chi 2 = 1.62, NS). Complete symptomatic improvement occurred in 9 of 24 patients receiving 4-ASA compared with 5 of 21 receiving prednisolone (chi 2 = 0.98, NS). Histological improvement was seen in 9 of 24 patients on 4-ASA compared with 7 of 21 on prednisolone (chi 2 = 0.08, NS). One patient receiving 4-ASA was considered to have an idiosyncratic reaction to the drug but other side effects were not considered to be drug related. Thus, 4-ASA, previously used in the treatment of tuberculosis (para-aminosalicyclic acid), is as good as prednisolone in the treatment of distal ulcerative colitis and should be considered in patients unresponsive to steroids or in whom steroid treatment is undesirable.

Abstract
The effect of budesonide, 1, 2, and 4 mg/100 ml in daily enemas, on active distal ulcerative colitis was compared with that of prednisolone disodium phosphate enemas, 25 mg/100 ml, in a multicentre, randomized, group-comparative trial. A total of 146 patients with active disease were treated for 2 weeks. Data from 139 were valid for statistical analyses. Bowel habits, proctoscopy findings, and histologic pictures were evaluated, and plasma cortisol was determined for measurement of influence on the hypothalamic-pituitary-adrenal axis. Clinical symptoms and proctoscopy findings improved within all treatment groups. The improvement of these effect variables tended to be less after treatment with the lowest dose of budesonide, 1 mg/100 ml, than after the other treatments. Plasma cortisol did not change in any of the budesonide groups, whereas a mean reduction of 30% (P = 0.07) was observed after prednisolone. It can be concluded that budesonide enemas of 2 mg/100 ml constitute an attractive alternative to prednisolone enemas for topical treatment of distal ulcerative colitis.

Abstract
In a prospective study, 37 consecutive patients with radiation-induced proctosigmoiditis were randomized to receive a four-week course of either 3.0 g oral sulfasalazine plus 20 mg twice daily rectal prednisolone enemas (group I, N = 18) or 2.0 g twice daily rectal sucralfate enemas plus oral placebo (group II, N = 19). The two groups were comparable with respect to demographic features, duration of symptoms, and clinical and endoscopic staging of the disease. Fifteen patients in group I and 17 in group II completed the trial. At four weeks, both groups showed significant clinical improvement (P less than 0.01 for group I and P less than 0.001 for group II) and endoscopic healing (P less than 0.01 for group I and P less than 0.001 for group II). When the two groups were compared, sucralfate enemas showed a significantly better response as assessed clinically (P less than 0.05), although endoscopically the response was not statistically different (P greater than 0.05). We conclude that both treatment regimens are effective in the management of radiation proctitis. Sucralfate enemas give a better clinical response, are tolerated better, and because of the lower cost should be the preferred mode of short-term treatment.

Abstract
The growth of knowledge in the field of the pharmacokinetics of prednisolone/prednisone has been slow for several reasons. First, convenient and specific methods for measuring these steroids only became available with the development of high performance liquid chromatographic methods. Secondly, prednisolone is nonlinearly bound to transcortin and albumin: since the unbound concentrations of prednisolone are biologically relevant, it was necessary to determine the free fraction in each plasma sample. Thirdly, due to the short half-life of prednisolone no steady-state is achieved, and therefore area under the concentration-time curve needed to be determined in all studies. Fourthly, prednisolone and prednisone are interconvertible and prednisolone is given intravenously as an ester prodrug, features which created controversies about the correct interpretation of pharmacokinetic results. Finally, the total body clearances of total and (to a lesser degree) of unbound prednisolone increase with increasing concentrations of prednisolone. Therefore, in order to compare pharmacokinetic results between different subjects, standardised doses had to be administered. The investigations performed so far have revealed that: (1) the dose-dependent pharmacokinetics partly explain the clinical observation that an alternate-day regimen with prednisone yields fewer biological effects; (2) the interconversion of prednisone into prednisolone is not a limiting factor, even in patients with severely impaired liver function; (3) hypoproteinaemia per se does not cause increased unbound concentrations of prednisolone in vivo; (4) patients with liver failure, renal failure or a renal transplant, subjects older than 65 years, women on estrogen-containing oral contraceptive steroids or subjects taking ketoconazole have increased unbound concentrations of prednisolone-whereas hyperthyroid patients, some patients with Crohn's disease, subjects taking microsomal liver enzyme-inducing agents or patients on intravenous prednisolone phthalate (instead of prednisolone phosphate) or on some brands of enteric coated prednisolone tablets have decreased concentrations of prednisolone. The biological relevance of the altered pharmacokinetics is supported in part by altered clinical effects and altered effects on cellular immunofunctions.

Abstract
Sixteen patients with 18 attacks of distal ulcerative colitis were treated randomly with either 0.5 mg topically administered beclomethasone dipropionate (BDP) or 5 mg betamethasone phosphate (BMT). The effect of the steroid enemas on adrenocortical function was examined by ACTH tests, which were performed before and 20 days after treatment. At completion of the trial, a marked suppression of the adrenocortical function was found in seven of eight patients treated for nine attacks with BMT but not in any patients in the BDP group (P less than 0.01). The mean posttreatment basal and stimulated plasma cortisol levels in the BMT group were significantly lower as compared with the BDP group. The overall therapeutic response assessed by score systems was comparable in the two treatment groups. It is concluded that, in the topical treatment of ulcerative colitis, BDP is preferable to BMT because it exerts an equal anti-inflammatory action without affecting adrenocortical function.

Abstract
A double blind multicentre study comparing sodium cromoglycate (600 mg/100 ml) by enema with prednisolone (20 mg/100 ml) by enema is reported. The study was conducted over a nine week period in the treatment of 70 patients with ulcerative colitis. Analysis of symptoms showed significant decreases in scores for patients in both groups, both at four and eight weeks; the only difference between the two groups was a significantly greater improvement in the reduction of rectal bleeding after four weeks in the prednisolone group. On sigmoidoscopy, both treatment groups showed a highly significant improvement after four and eight weeks with no significant differences being seen between the groups. Histology of the rectal biopsies showed a significant improvement in the inflammation of the mucosa for both treatment groups after four and eight weeks with no differences being observed between the groups. There were no significant changes in eosinophils from baseline and no difference between the groups at four and eight weeks.

Abstract
A double blind controlled trial has been conducted in 40 patients to compare the therapeutic effects of prednisolone metasulphobenzoate enemas with those of prednisolone-21-phosphate enemas. Both enemas brought about improvement in symptoms and sigmoidoscopic appearances in more than 70% of patients treated. The absorption of prednisolone from the metasulphobenzoate enema in three patients was less than from the 21-phosphate enema. In view of the low plasma prednisolone concentrations obtained, there are theoretical advantages in using a poorly absorbed enema to avoid the possibility of systemic steroid effects in patients requiring long term steroid treatment.

Abstract
5-aminosalicylic acid (5-ASA) is a new treatment for patients suffering from ulcerative colitis but only limited information is available about its rectal absorption. We therefore studied seven patients with ulcerative colitis in remission, and five with active disease to determine acetylated and free 5-ASA plasma concentrations and urinary acetyl 5-ASA after the administration of three different types of enemas: (2 g 5-ASA/100 ml, 4 g/100 ml, and 200 ml). In patients in remission urinary acetyl 5-ASA excretion was dose and volume dependent (p less than 0.01; p less than 0.05) but this correlation was absent in active disease. Because aminosalicylates are usually eliminated through the kidney, these low values (10% in active disease and 19% in those in remission) suggest that the beneficial action may be local. Urinary recovery was significantly lower in patients with active disease (p less than 0.01; p less than 0.02). No accumulation of 5-ASA was found in plasma after repeated daily administration.

Abstract
The therapeutic efficacy of prednisolone metasulphobenzoate enemas in the treatment of distal colitis has been compared with that of low-dose oral prednisolone, in a single-blind, cross-over trial. Treatment with steroid enemas resulted in symptomatic and sigmoidoscopic evidence of improvement more frequently than treatment with a dosage of oral steroid calculated to achieve similar plasma prednisolone levels. In addition to demonstrating, for the first time, that prednisolone metasulphobenzoate enemas are effective in the treatment of colitis, this study suggests that their efficacy is due to a local action rather than systemic absorption.

Abstract
Although the etiology of inflammatory bowel disease is unknown and specific therapy is unavailable, enough information on existing empiric agents is available to allow rational therapy. These agents include sulfasalazine, steroids, immunosuppressive drugs, metronidazole and cholestyramine. Sulfasalazine is a two-part molecule that depends on bacterial cleavage in the colon to deliver locally acting 5-aminosalicylate, whose mechanism of action may relate to inhibition of prostaglandin synthesis. The other half of the molecule, sulfapyridine, is responsible for most of the side effects of the drug. While the efficacy of sulfasalazine in the treatment and prevention of attacks of ulcerative colitis is well established, its use in Crohn's disease appears to be limited to patients with active colitis and ileo-colitis. Sulfasalazine is of major benefit in preventing relapses in patients with ulcerative colitis in remission. New formulations of 5-aminosalicylate may allow delivery of the apparently active moiety to the small bowel and colon without concomitant sulfapyridine toxicity. Corticosteroids are highly effective in acute attacks of ulcerative colitis and Crohn's ileitis and ileo-colitis; the mechanism of antiinflammatory action remains speculative. However, maintenance therapy with steroids is ineffective in preventing relapses or recurrent attacks of either ulcerative colitis or Crohn's disease. Steroid enemas allow topical administration to patients with distal colitis and proctitis with few systemic side effects. In children with growth failure associated with active Crohn's disease, amelioration by steroid therapy may actually restore normal growth. Immunosuppressive agents such as azathioprine and 6-mercaptopurine are of little value in active Crohn's disease when administered alone; however, in combination with other agents they may help diminish steroid dose, close fistulae and prevent relapse. Their mode of action likely depends on long-term cytostatic effects on immune effector cells. Concern for leukopenia and the development of late malignancy has limited their use to patients not responding to other therapies. Metronidazole, an antimicrobial agent that is effective against anaerobes, has recently been shown useful in Crohn's disease involving the colon and perianal area. Its mechanism of action is uncertain, but may be related to its antibacterial actions on anaerobes. Cholestyramine can be successfully used to control bile salt-induced diarrhea in Crohn's patients with terminal ileal resections. Effective drug therapy of inflammatory bowel disease is only part of a total program of management including reassurance, frequent explanation, well-timed use of surgery, and an understanding physician.

Abstract
Thirty patients with distal colitis (proctosigmoiditis) in relapse were randonly allocated to twice daily treatment with traditional aqueous hydrocotrisone enemas (Cortenemas) or a suspension of hydrocortisone in an inert foam base (Colifoam). Each treatment contained the same amount of hydrocortisone. Clinical, sigmoidoscopic, and histological response was assessed after two weeks. Both agents were effective, and broadly similar in terms of objective improvement, but subjective improvement was greater with the foam preparation, and several patients expressed a preference to this mode of treatment.

Abstract
Plasma prednisolone levels have been compared in healthy volunteers and in patients suffering from idiopathic proctocolitis after the administration of standard retention enemata containing either prednisolone-21-phosphate or prednisolone metasulphobenzoate sodium. The levels were significantly lower after the latter, irrespective of the presence or degree of activity of the disease. Prednisolone metasulphobenzoate appeared to be as effective as the 21-phosphate ester for the treatment of proctocolitis in the few patients where the two drugs were compared. It seems possible that the beneficial effect of the form of therapy is exerted predominantly locally, rather than by systemic action.

The effect on plasma levels of altering the formulation of the enteric-coating has also been studied. 2 The presence of food in the stomach at the time of administration does not affect the absorption of enteric-coated prednisolone tablets. 3 There was considerable inter-subject variation in plasma prednisolone levels after administration of shellac based enteric-coated tablets. However, plasma levels were more consistent when a preparation whose formulation was based upon cellulose acetate phthalate (CAP) was given. 4 It is concluded that the pattern of absorption and plasma prednisolone levels depend on the formulation of the enteric coating. The bioavailability of the CAP based preparation is similar to that of plain prednisolone.
