Ulcerative colitis in an adult patient mimicking Henoch-Schönlein purpura: A case report.

RATIONALE: Ulcerative colitis (UC) is one of the chronic inflammatory diseases of the intestinal tract. UC being misdiagnosed as Henoch-Schönlein purpura (HSP) in the elderly has seldom been reported about. PATIENT CONCERNS: A 64-year-old man was admitted to the hospital with petechiae and palpable purpura in lower limbs and abdominal pain for about 1 month. DIAGNOSES: Colonoscopy demonstrated severe inflammation in the colon, mucosal congestion, and edema, and multiple hemorrhages and ulcerations, with purulent adhesions. A histopathologic examination of the colon biopsies revealed extensive infiltration of immune cells and mucosal ulcerations in the intestine. UC was diagnosed. INTERVENTIONS: The patient was treated with prednisone (1.0 mg/kg/d) with progressive dose reduction. OUTCOMES: The skin lesions were healed within 4 weeks, and his abdominal pain was alleviated remarkably. He is currently under follow-up. LESSONS: As the treatment used for patients with HSP was not effective, it was advised that UC should be taken into consideration.

Increased serum resistin levels correlate with psoriasis: a meta-analysis.

BACKGROUND: Recent studies implicate adipokines in the pathogenesis of inflammatory diseases, including psoriasis. In this study we evaluated the significance of serum resistin levels in psoriasis patients using a meta-analysis approach.223 METHODS: Relevant articles were retrieved by searching the following English and Chinese databases: Cochrane Library, PubMed, Springer Link, Chinese Biomedical Database (CBM) and Chinese National Knowledge Infrastructure (CNKI). The retrieved studies were subjected to a thorough screening procedure to identify case-control studies that contained the required data. Data was extracted from each study and Version 12.0 STATA statistical software was employed for statistical analyses. RESULTS: Nine case-control studies, containing 421 psoriasis patients and 348 healthy controls, were included in this study. The major result of the meta-analysis revealed a statistically significant association between serum resistin levels and psoriasis (SMD=2.22, 95%CI: 1.14-3.29, P<0.001). Subgroup analysis based on ethnicity showed that, compared to the healthy controls, serum resistin levels were markedly higher in psoriasis patients in both Asian and Caucasian populations (Asians: SMD=3.27, 95%CI=1.62~4.91, P<0.001; Caucasians: SMD=0.91, 95%CI=0.28~1.54, P<0.001). CONCLUSIONS: Based on our results, we conclude that serum resistin level in psoriasis patients is higher than healthy controls, and raises the possibility that elevated serum resistin levels may be a novel diagnostic marker in psoriasis and may predict the occurrence of co-morbidities in psoriasis patients.
