Acute Acalculous Cholecystitis Associated with Epstein-Barr Infection: A Case Report and Review of the Literature.

The most common cause of acute cholecystitis (ACC) is cholelithiasis. Acute acalculous cholecystitis (AAC) is well documented in the literature related with critical illness, but viral causes such as cytomegalovirus (CMV) and Epstein-Barr virus (EBV) have also been reported. We present a rare manifestation of EBV infection, reporting a case of a 15-year-old female suffering from acute acalulous cholecystitis, and we review the relevant literature. Clinicians should be aware of this rare complication of EBV infection and properly exclude it in young patients with cholecystitis.

Higher free serum cortisol is associated with worse survival in acute variceal bleeding because of cirrhosis: a prospective study.

BACKGROUND AND AIMS: Critical illness-related corticosteroid insufficiency has been reported in acute variceal bleeding (AVB). In cirrhosis, free serum cortisol (FC) is considered optimal to assess adrenal function. Salivary cortisol (SC) is considered a surrogate for FC. We evaluated FC and its prognostic role in AVB. METHODS: Total serum cortisol, SC, cortisol-binding globulin, and FC (Coolens' formula) were evaluated in AVB (n=38) and in stable cirrhosis (CC) (n=31). A Cox proportional hazards model was evaluated for 6-week survival. RESULTS: In AVB, the median FC and SC levels were higher with worse liver dysfunction [Child-Pugh (CP) A/B/C: 1.59/2.62/3.26 µg/dl, P=0.019; CPA/B/C: 0.48/0.897/1.81 µg/ml, P<0.001, respectively]. In AVB compared with CC, median total serum cortisol: 24.3 versus 11.6 µg/dl (P<0.001), SC: 0.86 versus 0.407 µg/ml (P<0.001); FC 2.4 versus 0.57 µg/dl (P<0.001). In AVB, 5-day rebleeding was 10.5%, and 6-week and total mortality were 21.1 and 23.7%, respectively. Independent associations with 6-week mortality in AVB were FC at least 3.2 µg/dl (P<0.001), hepatocellular carcinoma (P<0.001), CPC (P<0.001), and early rebleeding (P<0.001). Among patients with normal cortisol-binding globulin (n=14) and albumin (n=31), the factors were hepatocellular carcinoma (P=0.003), CP (P=0.003), and FC (P=0.036). SC was also found to be an independent predictor of 6-week mortality (P<0.001). Area under the curve of FC for predicting 6-week mortality was 0.79. CONCLUSION: Higher FC is present in cirrhosis with AVB compared with CC and is associated independently with bleeding-related mortality. However, whether high FC solely indicates the severity of illness or whether there is significant adrenal insufficiency cannot be discerned.

Health-related quality of life in patients with inflammatory bowel disease: a single-center experience.

BACKGROUND: Inflammatory bowel disease (IBD) has a negative impact on health-related quality of life (HRQoL). The aim of the study was to assess HRQoL of IBD patients in South-Western Greece. METHODS: 89 IBD patients [38 (42.7%) Crohn's disease (CD), 51 (57.3%) ulcerative colitis (UC)] were included. HRQoL was assessed using IBD questionnaire (IBDQ), which tests four health domains: bowel symptoms (BS), systemic symptoms (SS), emotional function (EF) and social function (SF). Total score (TS) ranges from 32 to 224. Disease activity was measured using Crohn's Disease Activity Index (CDAI) (CD), and Truelove and Witts classification (UC). The impact of epidemiological and disease-specific characteristics on IBDQ was studied. RESULTS: No statistically significant difference was found in all IBDQ scores between UC and CD patients. No correlation was found regarding age, sex, smoking, anemia, disease duration and use of corticosteroids, 5-aminosalicylates or immunosuppressives with HRQoL. The factors found to have a major negative impact on all IBDQ scores was disease severity both in CD and UC, and education on bowel symptoms in CD. On multivariate analysis, only high disease activity had significant effects on total and dimensional scores of IBDQ in UC (TS, P=0.005; BS, P<0.001; SS, P=0.004; EF, P=0.05; SF, P=0.001), whereas in CD, only CDAI (TS, P=0.001; BS, P=0.004; SS, P=0.001; EF, P=0.003; SF, P=0.003) and education (TS, P=0.047; BS, P=0.004; SS, P=0.03) had significant effects. CONCLUSIONS: IBD patients in remission experience better HRQoL than patients with active disease. Induction of remission should become the mainstay of care regarding improvement in HRQoL.

Adiposity factors are not related to the presence of colorectal adenomas.

PURPOSE: Adiposity has been thought to be related to colorectal carcinogenesis. The aim of this study was to explore any association between obesity factors and the presence of colorectal adenoma, a potential precancerous lesion. PATIENTS AND METHODS: Two hundred and six consecutive patients undergoing colonoscopy without colorectal cancer were enrolled in the study. Anthropometric measures and other adiposity-related laboratory variables including insulin resistance and serum adiponectin levels were recorded and correlated with the presence of adenoma. RESULTS: Colorectal adenoma was detected in 68/206 patients (33%), tubular adenoma(s) in 38 patients, and tubulovillous or villous in 30 patients. Twenty-one patients (10.2%) had at least one proximal polyp. The size of the largest adenoma was ≤10 mm in 40 patients and >10 mm in 28 patients. No statistically significant difference was observed in body mass index, waist circumference, fasting plasma glucose concentration, insulin, homeostatic metabolic assessment, cholesterol, low-density lipoproteins, high-density lipoprotein, or triglycerides between patients with and without adenoma. In addition, there was no difference in plasma adiponectin between patients with adenoma (11.1 ± 6 µg/mL) and controls (10.2 ± 7.8 µg/mL). Furthermore, no significant difference in any parameter was found between patients with advanced adenoma and no advanced adenoma, nor between patients with proximal or distal tumors. CONCLUSION: This study found that the presence of colorectal adenoma is not correlated with any adiposity factor. Moreover, obesity does not appear to be associated with the site or the presence of more advanced lesions.
