Efficacy of topical 5-aminosalicylate monotherapy in patients with ulcerative proctitis with skip inflammation.

BACKGROUND AND AIM: In some patients with ulcerative proctitis (UP), skip inflammation is noted in the right side of the colon, but little is known about its clinical course. The aim of this study was to evaluate the clinical course of UP with skip inflammation and the efficacy of topical 5-aminosalicylate (5-ASA) monotherapy. METHODS: This study reviewed the data of 388 patients with an initial diagnosis of UP from January 2005 to October 2015. This study matched each UP patient with skip inflammation 1:2 with controls who had UP without skip inflammation; to reduce bias, this study matched the controls with the cases by age, gender, and initial disease activity. RESULTS: During the follow-up period (median: 69.5 months), the overall progression rates for the control group (n = 192) and the skip inflammation group (n = 96) were 24.0% and 32.9% at 10 years, respectively (log-rank P = 0.71). In the skip inflammation group, the progression rates were not significantly different between the 5-ASA combination group and the topical group, 33.4% and 26.6% at 10 years, respectively (log-rank P = 0.96). The overall acute exacerbation rates for the control and skip inflammation groups were 17.2% and 26.8% at 10 years, respectively (log-rank P = 0.68). In the skip inflammation group, the exacerbation rates were also not significantly different between the combination and topical treatment groups, 26.6% and 23.6% at 10 years, respectively (log-rank P = 0.88). CONCLUSION: The clinical course of UP with skip inflammation was not different from that of typical UP, and topical 5-ASA monotherapy for maintaining remission was as effective as 5-ASA combination therapy irrespective of the presence of skip lesions.

Budesonide foam induces remission in patients with mild to moderate ulcerative proctitis and ulcerative proctosigmoiditis.

BACKGROUND & AIMS: Budesonide is a high-potency, second-generation corticosteroid designed to minimize systemic adverse consequences of conventional corticosteroids. We performed 2 randomized, phase 3 trials to evaluate the ability of budesonide rectal foam, formulated to optimize retention and provide uniform delivery of budesonide to the rectum and distal colon, to induce remission in patients with ulcerative proctitis or ulcerative proctosigmoiditis. METHODS: Two identically designed, randomized, double-blind, placebo-controlled trials evaluated the efficacy of budesonide foam for induction of remission in 546 patients with mild to moderate ulcerative proctitis or ulcerative proctosigmoiditis who received budesonide foam 2 mg/25 mL twice daily for 2 weeks, then once daily for 4 weeks, or placebo. RESULTS: Remission at week 6 occurred significantly more frequently among patients receiving budesonide foam than placebo (Study 1: 38.3% vs 25.8%; P = .0324; Study 2: 44.0% vs 22.4%; P < .0001). A significantly greater percentage of patients receiving budesonide foam vs placebo achieved rectal bleeding resolution (Study 1: 46.6% vs 28.0%; P = .0022; Study 2: 50.0% vs 28.6%; P = .0002) and endoscopic improvement (Study 1: 55.6% vs 43.2%; P = .0486; Study 2: 56.0% vs 36.7%; P = .0013) at week 6. Most adverse events occurred at similar frequencies between groups, although events related to changes in cortisol values were reported more frequently with budesonide foam. There were no cases of clinically symptomatic adrenal insufficiency. CONCLUSIONS: Budesonide rectal foam was well tolerated and more efficacious than placebo in inducing remission in patients with mild to moderate ulcerative proctitis and ulcerative proctosigmoiditis. ClinicalTrials.gov ID: NCT01008410 and NCT01008423.

Budesonide Foam Has a Favorable Safety Profile for Inducing Remission in Mild-to-Moderate Ulcerative Proctitis or Proctosigmoiditis.

BACKGROUND: Budesonide foam, a rectally administered, second-generation corticosteroid with extensive hepatic first-pass metabolism, is efficacious for the treatment of mild-to-moderate ulcerative proctitis and ulcerative proctosigmoiditis. AIM: The aim of this study was to comprehensively assess the safety and pharmacokinetic profile of budesonide foam. METHODS: Data from five phase III studies were pooled to further evaluate safety, including an open-label study (once-daily treatment for 8 weeks), an active-comparator study (once-daily treatment for 4 weeks), and two placebo-controlled studies and an open-label extension study (twice-daily treatment for 2 weeks, then once daily for 4 weeks). Data from the placebo-controlled studies and two phase I studies (i.e., patients with mild-to-moderate ulcerative colitis and healthy volunteers) were pooled to evaluate the pharmacokinetics of budesonide foam. RESULTS: A similar percentage of patients reported adverse events in the budesonide foam and placebo groups, with the majority of adverse events being mild or moderate in intensity (93.3 vs 96.0%, respectively). Adverse events occurred in 41.4 and 36.3% of patients receiving budesonide foam and placebo, respectively. Mean morning cortisol concentrations remained within the normal range for up to 8 weeks of treatment; there were no clinically relevant effects of budesonide foam on the hypothalamic-pituitary-adrenal axis. Population pharmacokinetic analysis demonstrated low systemic exposure after budesonide foam administration. CONCLUSIONS: This integrated analysis demonstrated that budesonide foam for the induction of remission of distal ulcerative colitis is safe overall, with no clinically relevant effects on the hypothalamic-pituitary-adrenal axis.

[First line therapy of inflammatory bowel disease]. / Traitement de première ligne des maladies inflammatoires chroniques de l'intestin.

During the last decade, anti-TNF agents and emergence of new therapeutic concepts have dramatically changed inflammatory bowel disease (IBD) management, especially at their early phase. Salicylates remain the therapeutic basis in ulcerative colitis while their efficacy in Crohn's disease has not been confirmed. A rapid step-up approach is considered for managing IBD at early phase providing early immunomodulators--such as immunosuppressant and anti-TNF--in case of poor disease course. Some specific situations (severe, extended or complicated forms) require the most efficient first-line therapy that is combination between anti-TNF and immunosuppressant. A close follow-up not only based on clinical symptoms, but also on objective inflammatory tools (endoscopy, cross-sectional imaging, biomarkers), is needed to adjust medical therapy rapidly in order to prevent complications and surgery.

Latent viral infections in young patients with inflammatory diseases treated with biological agents: prevalence of JC virus genotype 2.

Treatment with biological drugs is associated with increased susceptibility to viral infections. Reactivation of JC virus (JCV) and human cytomegalovirus (HCMV) in adults after therapy has been documented. The long-term effects of biological and conventional therapy on human herpesviruses and polyomaviruses infections in young patients were assessed. One hundred eighty-six samples [urine, serum, and blood cells (PBMCs)] from 62 patients (15.8 ± 6.2 years old) with Crohn's disease, ulcerative rectocolitis or juvenile rheumatoid arthritis treated with immunotherapy or conventional therapy for over 12 months were tested by real time PCR. One hundred twenty-four samples (urine and blood) from 62 matched healthy volunteers (13.8 ± 8.6 years old) were included as controls. Sequencing of the JCV viral protein 1 (VP1) and transcriptional control region (TCR) was performed. Herpes simplex virus 1/2 and varicella zoster virus genomes were not detected in any patients, whereas Epstein-Barr virus, HCMV, and human herpesvirus-6 genomes were detected in 4.8%, 3.2%, and 1.6% of the patients, respectively. JCV was detected in 22.6% (14/62) of urine samples from patients and in 8% (5/62) from controls, in 50% (7/14) of sera from patients shedding JCV, and in 71.4% (5/7) of matched PBMCs. There was a significant association between infliximab treatment and excretion of JCV genotype 2. Subclinical infection/reactivation of JCV genotype 2 in young patients during infliximab therapy was demonstrated. Conversely, increased susceptibility to herpesviruses infection was not shown. Future studies are warranted to investigate the effects of JCV reactivation on the health of young patients treated with infliximab.

Placebo controlled evaluation of Xilei San, a herbal preparation in patients with intractable ulcerative proctitis.

BACKGROUND AND AIM: Topical mesalamine or corticosteroid has shown efficacy in patients with ulcerative proctitis, but patients often become refractory to these interventions. Xilei San is a herbal preparation with evidence of anti-inflammatory effects. We evaluated the efficacy of topical Xilei San in ulcerative proctitis patients. METHODS: In a double blind setting, 30 patients with intractable ulcerative proctitis despite ≥ 4 weeks of topical mesalamine or corticosteroid were randomly assigned to True (n = 15) and placebo (n = 15). Patients in True received suppository Xilei San (0.1 g/dose per day of Xilei San), the other 15 received placebo suppository. The initial efficacy was evaluated on day 14. Primary endpoint of the trial was avoiding relapse during 180 days, relapse meant recurrence of active disease. Riley's index was applied for endoscopic and histological evaluations, while patients' quality of life was evaluated by an inflammatory bowel disease questionnaire. RESULTS: On day 14, the number of patients who achieved remission, clinical activity index ≤ 4 in True was significantly higher versus placebo (P < 0.04). Likewise, at day 180, an 81.8% of patients in True were without relapse versus 16.7% in placebo (P < 0.001). Further, significant endoscopic (P < 0.01), histological (P < 0.02) and inflammatory bowel disease questionnaire (P < 0.04) improvements were observed in True, but not in placebo. CONCLUSIONS: This is the first controlled investigation showing significant clinical and endoscopic efficacy for Xilei San in patients with intractable ulcerative proctitis. Topical Xilei San was well tolerated, and was without safety concerns.

Real-world evidence of quality of life improvement in patients with distal ulcerative colitis treated by mesalazine: the Quartz study.

BACKGROUND: Distal ulcerative colitis (UC) is responsible for distressing symptoms and reduces quality of life (QoL). Oral and topical formulations of 5-amino-salicylic acid are the first line therapy for mild to moderate distal UC. OBJECTIVE: Our aim was to evaluate the impact of mesalazine treatment for mild to moderate ulcerative proctitis and proctosigmoiditis on patient QoL. METHODS: Ninety-three patients with mild to moderate ulcerative proctitis and proctosigmoiditis, initiating a treatment with Pentasa, were prospectively included. The primary endpoint was the change from baseline to W8 in patient health-related QoL (HRQoL) as measured by the Short Inflammatory Bowel Disease Questionnaire (SIBDQ) total score. RESULTS: More than 80% of patients were prescribed with a rectal formulation, either alone (47.9%) or with an oral formulation (35.1%), and 17.0% of patients were prescribed oral formulation alone. Mean SIBDQ score was improved at W8 in patients affected with mild and moderate disease ( P < 0.001 versus baseline in both groups, as well as in patients who achieved clinical remission ( P < 0.001). Patients who achieved clinical remission at W8 reached a mean change of +6.7 (±7.1), whereas those who did not achieve clinical remission had a mean change of +1.1 (±8.9). Seventy-five per cent of patients had an improvement of their disability index at W8. Fecal incontinence was also improved at W8. CONCLUSION: HRQoL measuring with the SIBDQ is proportionally related to disease activity in patients with distal UC treated with mesalazine.

[Lymphogranuloma venereum proctocolitis in men with HIV-1 infection]. / Respuesta completa al tratamiento con doxiciclina en pacientes con infección por VIH-1 con proctitis por linfogranuloma venéreo.

INTRODUCTION: We present a series of 15 cases with lymphogranuloma venereum (LGV) with the aim of evaluating the response to a 21-day oral course of doxycycline (100mg twice daily). PATIENTS AND METHODS: It is an observational study where we describe a series of cases with LGV diagnosed in the Hospital Germans Trias i Pujol's HIV Unit between March 2008 and April 2009. RESULTS: All our patients were HIV infected men who had sex with men with proctitis in 80% of the cases. In all of them Chlamydia trachomatis was determined by PCR on rectal swab specimens, with a negative result after 21 days of treatment with doxycycline. Serovar L2 was confirmed in all the specimens with the reverse hybridization technique. DISCUSSION: A high index of clinical suspicion is the mainstay to the early diagnosis of LGV since the clinical presentation remains unspecific. The treatment with doxycycline eradicates C. trachomatis in HIV patients with LGV.

Mesalazine-induced interstitial nephritis.

5-aminosalicylate compounds (mesalazine, sulfasalazine) are widely used in therapy of inflammatory bowel diseases. Mesalazine-induced interstitial nephritis is a rare complication; however, the morbidity in an affected individual is high. Regular renal screening in patients treated with 5-aminosalicylate compounds is important. A 15-year-old boy with treated idiopathic proctocolitis, consequent mesalazine-induced nephritis, and a favorable response to corticotherapy is presented.

Acetarsol in the management of mesalazine-refractory ulcerative proctitis: a tertiary-level care experience.

BACKGROUND: Mesalazine-refractory ulcerative proctitis is common, with a significant proportion of the patients requiring escalation to immunomodulators or biological therapy. Three small preliminary cohort studies suggested good clinical efficacy for the organic arsenic derivative acetarsol in the management of proctitis. Our aim was to describe our experience on the use of acetarsol in proctitis and to review all existing evidence on its safety and efficacy. PATIENTS AND METHODS: We retrospectively reviewed clinical records of all ulcerative colitis patients exposed to acetarsol at Nottingham University Hospitals since 2012. Clinical response was determined basing on physicians' global assessments and patients' improvement over the baseline (reduction in stool frequency and rectal bleeding). Clinical remission was defined as total resolution of symptoms including bleeding cessation. Serum arsenic, C-reactive protein and faecal calprotectin levels reviewed when available. Nonparametric analysis performed. RESULTS: Twenty-eight (16 males) patients with median (range) age 39 (35) and 9 (19) years disease duration received acetarsol suppositories for proctitis. All had failed mesalazine or corticosteroid topical therapy, with 50% having additionally failed immunomodulators. Median treatment duration was 70 (64) days. 16/28 were prescribed acetarsol more than once. 67.9% achieved clinical response and 46.4% clinical remission. 32.1% required treatment escalation to steroids, thiopurines or antitumour necrosis factor agents. 6/28 patients stopped acetarsol due to side effects. CONCLUSION: Acetarsol could be an effective and safe option in the management of refractory proctitis. A definitive trial with long-term safety follow-up is required to investigate the efficacy and safety of this promising drug.

Mesalamine foam enema versus mesalamine liquid enema in active left-sided ulcerative colitis.

AIM: To determine in a noninferiority study whether mesalamine foam is as effective as mesalamine liquid enema for inducing clinical remission in patients with active left-sided ulcerative colitis (UC). METHODS: In a multicenter investigator-blind trial, 375 patients with mild-to-moderate UC were randomized to receive mesalamine foam 1 g/80 mL/day or mesalamine liquid enema 1 g/100 mL/day for 4 wk (W). Inclusion criteria were: disease extension at least 5 cm from anorectal junction and not above splenic flexure and Clinical Activity Index (CAI) 1-4 > or = 4. Primary end point was clinical remission at W4 defined as a CAI 1-4 < or = 2. Noninferiority of the foam to liquid enema was declared if the lower limit of the 97.5% unilateral confidence interval (97.5% CI) of the difference in remission rates between foam and liquid enema groups was greater than -15% . RESULTS: Remission rates at W4 in foam versus liquid were 68.3%versus 73.6% in per protocol (PP) population (lower limit of 97.5% CI -15.1%) and 66.7%versus 70.5% in intention-to-treat (ITT) population (97.5% CI -13.4%). Remission rates at W2 were 48.1 %versus 50.6% in ITT (97.5% CI -12.8%) and 49.1%versus 52.1% in PP (97.5% CI -13.8%) in foam versus liquid, respectively. Both treatments were well tolerated. CONCLUSIONS: A 4-wk treatment of 1 g mesalamine foam induced a clinical remission in 68% patients versus 73% with 1 g mesalamine liquid enema. Although the noninferiority of mesalamine foam could not be strictly demonstrated at W4 in the PP analysis, it was achieved in the ITT population and at W2 in both populations. Mesalamine foam represents a therapeutic alternative to mesalamine liquid enema in patients with mild-to-moderate active proctitis and proctosigmoiditis.

Autoimmune Pancreatitis and Ulcerative Rectocolitis in an Adolescent.

Autoimmune pancreatitis (AIP) is rare in teenagers and difficult to diagnose. There are no clear and established diagnostic criteria in the pediatric population to distinguish subtype 1 and subtype 2. Here, we report the case of a 16-year-old white French teenager admitted to the pediatric emergency service with more than 1 year's history of pain originating from the epigastric and the right hypochondriac regions, with bloody diarrhea. After exclusion of pancreatic cancer and other common causes of acute pancreatitis, the diagnosis of AIP was suspected. Biological analyses revealed acute pancreatitis with severe cholestasis and an elevated level of serum immunoglobulin G4. Magnetic resonance cholangiography revealed a voluminous pancreas presenting a typical "sausage-like" aspect. Anatomopathological analyses of the liver biopsy specimen revealed a biliary obstruction due to pancreatic involvement without the typical aspect of chronic destructive cholangitis. Corticotherapy and immunosuppressive treatment proved effective after 1 week of treatment. Without a pancreatic biopsy specimen, the distinction between AIP type 1 and 2 could not be made clearly in this case. The succession of clinical observations could allow clinicians to recognize, treat, and manage AIP in children.
