Primary biliary cirrhosis is more severe in overweight patients.

GOALS: We sought to determine whether features of metabolic syndrome (MS) and histologic features of nonalcoholic steatohepatitis (NASH) are associated with increased fibrosis in patients with primary biliary cirrhosis (PBC). BACKGROUNDS: PBC is a chronic, progressive cholestatic disease. MS is strongly associated with NASH and fibrosis progression in some liver diseases. STUDY: Patients with PBC seen consecutively at the University of Miami between 1985 and 2008 who had antimitochondrial antibody positivity and a liver biopsy performed at this center at the time of diagnosis were identified. Demographics, clinical features, and biochemical parameters were collected. All liver biopsies were reviewed by a single blinded pathologist for features of NASH, PBC, and fibrosis. The impact of NASH and features of MS on liver biopsy findings were analyzed. RESULTS: Forty-nine patients [median age 51 (34 to 78) years, 98% females] were enrolled. Higher degree of steatosis, severe inflammatory grade, and severe biliary duct damage were each associated with advanced fibrosis (P<0.0001). Regarding MS, only overweight status [body mass index (BMI) ≥ 25] was associated with nonalcoholic fatty liver activity score (NAS) ≥ 5 (P<0.0001), biliary duct damage (P<0.0001), and advanced fibrosis (71% vs. 32%, P=0.007). Patients with NAS ≥ 5 had more severe fibrosis (14/15, 96% vs. 11/34, 44%; P=0.0001) and more severe biliary duct damage (13/15, 87% vs. 3/34, 9%; P=<0.0001). CONCLUSIONS: NASH and BMI ≥ 25 are associated with severe biliary duct damage and fibrosis in patients with PBC. BMI could become a useful noninvasive tool to predict advanced fibrosis in PBC.

Cephalic vein aneurysm.

Cephalic vein aneurysms are rare malformations that may develop in any part of the vascular system, and their history, presentation, and management vary depending on their site. The etiology of venous aneurysms remains unclear, although several theories have been elaborated. Venous aneurysms are unusual vascular malformations that occur equally between the sexes and are seen at any age; they can present as either a painful or a painless subcutaneous mass. No serious complications have been reported from upper extremity venous aneurysms. Surgical excision is the definitive management for most of these. The case reported here presented with a painless and mobile, soft, subcutaneous mass that caused only cosmetic concern.
