    Abstract Background:,Candida sp are frequently isolated from the ascitic fluid of patients with perforated ulcers. The present study was performed to examine whether Candida infection may be involved in the process of ulcer perforation. Methods:, Male Wistar rats were divided into a saline group (n = 15) and a Candida group (n = 17). Cysteamine-HCl (Sigma; 31 mg/100 g) was administered thrice on day 1 to both groups of animals. Candida albicans at a density of 108 in 0.5 mL of saline was administered 1 h before, and 12 h and 24 h after the first administration of cysteamine in the Candida group. Results:, Perforated duodenal ulcers were observed in 94.1% of the rats in the Candida group, but only 26.7% of the rats in the saline group (P < 0.01). The area of the duodenal ulcers in the Candida group was 40.89 33.07 mm2, whereas that in the saline group was 16.53 20.4 mm2 (P < 0.05). The mortality rate was significantly higher in the Candida group than in the saline group. In the Candida group, colonization by C. albicans was recognized at the ulcer base, surrounded by marked granulocytic infiltration. The number of eosinophils infiltrating the ulcer base was also significantly greater in the Candida group than in the saline group. Immunohistochemical analysis revealed the expression of secretory aspartyl protease (SAP) in the region of the ulcer showing colonization by C. albicans in the Candida group. Conclusion:,Candida albicans aggravates duodenal ulcer perforation in the experimental model of cysteamine-induced duodenal ulcer perforation. The present findings suggest that SAP and host,parasite relationships, including granulocyte-dependent mechanisms, may be involved in the aggravation of ulcer perforation by C. albicans. [source]

    Summary Background, Peptic ulcer perforation is a serious surgical emergency with a substantial short-term mortality, but the influence of antipsychotic drug use on the prognosis remains unknown. Aim, To examine the association between antipsychotic drug use and 30-day mortality following peptic ulcer perforation. Methods, This cohort study comprised 2033 patients with a first-time hospitalization with peptic ulcer perforation, in Northern Denmark, between 1991 and 2004. Data on preadmission use of antipsychotics and other medications, psychiatric disease, other comorbidities and mortality were obtained through population-based medical databases. We used Cox regression analyses to compute adjusted mortality rate ratios (MRRs). Results, One hundred and sixteen (5.7%) patients with peptic ulcer perforation were current users of antipsychotic drugs at the time of hospital admission and 205 (10.1%) were former users. The overall 30-day mortality was 27%. Among current users of antipsychotics 30-day mortality was 39%. The adjusted 30-day MRR for current users of antipsychotic drugs compared with non-users was 1.7 (95% CI: 1.2,2.3). Former use was not a predictor of mortality. The increase in mortality was equal in users of conventional and atypical antipsychotics. Conclusion, Use of antipsychotic drugs is associated with substantially increased mortality following peptic ulcer perforation. [source]
