ABSTRACT
PURPOSE: To compare the standard treatment, diltiazem gel 2%, with Levorag® Emulgel for chronic anal fissures. METHODS: This was a single-blinded, randomised, controlled, clinical trial with a non-inferiority design. Patients with a chronic anal fissure were randomised to treatment with diltiazem or Levorag® Emulgel twice daily for 8 weeks. Primary endpoint was complete healing of the anal fissure after 12 weeks. Secondary endpoints included incidence of adverse events and efficacy on pain relief. RESULTS: In total, 55 patients were included. Inclusion was terminated prematurely due to a slow inclusion rate. Complete fissure healing at 12 weeks follow-up was overall achieved in 31 of 55 (56%) patients, 18 of 29 (62%) in the diltiazem group compared with 13 of 26 (50%) in the Levorag® Emulgel group (P = 0.424). Pain relief was significantly better at day seven in patients treated with diltiazem (P = 0.040) compared with Levorag® Emulgel, whereas there were no differences in early (3 days) or late (12 weeks) pain relief. Three patients (10.3%) developed severe perianal exanthema during diltiazem treatment, whereas no side effects were observed in the Levorag® Emulgel group. CONCLUSION: The study demonstrated statistical non-inferiority of Levorag® Emulgel compared with diltiazem in the treatment of chronic anal fissure. Diltiazem resulted in a more prompt pain relief and also in a substantial number of local allergic reactions. Levorag® Emulgel may therefore be an alternative in these patients.

OBJECTIVE: The aim of this study was to investigate plasma levels of serotonin, calcitonin and calcitonin gene-related peptide (CGRP) in the course of acute pancreatitis (AP) taking organ failure, etiology and severity into consideration. MATERIAL AND METHODS: Sixty consecutive patients with alcohol- or gallstone-induced AP were included over a 15-month period. Patients were treated according to a standardized algorithm and monitored for organ specific morbidity and mortality. Organ functions and blood samples were assessed on days 0, 1, 2 and 14 after hospital admission. Twenty healthy volunteers, matched for age and gender, comprised the reference group. RESULTS: Lower levels of serotonin were observed in patients at admission compared to healthy volunteers (p = .021). Serotonin levels increased from day 2 to 14 (p < .001), but with no relation to severity, etiology or organ failure. No difference in calcitonin levels was found in patients at admission compared to healthy volunteers. However, calcitonin levels decreased over time (p < .001) and higher levels were found in patients with respiratory failure (p = .039). No difference was observed in relation to severity or etiology. CGRP levels in patients at admission did not differ from healthy volunteers, nor did CGRP change over time or show any relationship to severity, etiology or organ failure. CONCLUSION: Our data suggest serotonin and calcitonin levels to be associated to time-course of AP, and calcitonin levels to organ dysfunction. We hypothesize that serotonin plays a pathogenic role in the compromised pancreatic microcirculation, and calcitonin a role as a biomarker of severity in AP.
