ABSTRACT BACKGROUND: Sarcopenia may affect patients with liver cirrhosis and worsen disease outcomes. OBJECTIVES: To evaluate ultrasound-measured psoas major (PM) and rectus abdominis (RA) thickness for predicting survival among patients with liver cirrhosis. DESIGN AND SETTING: Prospective cohort study in a tertiary-level hospital. METHODS: 61 patients with liver cirrhosis were prospectively included during a 15-month period and followed up for at least six months. Cirrhosis was classified using the Child-Pugh score. Sarcopenia was assessed using surrogate parameters: handgrip strength (HGS), mid-arm muscle circumference (MAMC) and SGA (subjective global assessment). We used ultrasound to measure RA and PM thickness at admission. RESULTS: There were 41 men. The patients’ mean age was 58.03 ± 10.8 years. 26.22% of them were Child-Pugh A, 45.9% B and 27.86% C. The patients were followed up for 11.9 ± 5.63 months. RA thickness correlated moderately with MAMC (r = 0. 596; P < 0.0001) and HGS (r = 0.515; P < 0.0001) and decreased with increasing SGA class (A, 10.6 ± 2.8 mm; B, 8.3 ± 1.9 mm; C, 6.5 ± 1.9 mm; P < 0.0001). Survival at six months was independently predicted by using the model for end-stage liver disease-serum sodium score (odds ratio, OR 1.305; 95% OR confidence interval 1.083-1.572; P = 0.005). Survival during follow-up was independently predicted by RA thickness (hazard ratio, HR 0.701; 95% HR confidence interval 0.533-0.922; P = 0.011) and ascites (HR 1.876; 95% HR confidence interval 1.078-3.267; P = 0.026). PM thickness did not have any predictive value. CONCLUSIONS: As a surrogate marker of sarcopenia, RA thickness may predict survival among patients with liver cirrhosis.

Aim: Perform a comparison between adalimumab (ADA) and infliximab (IFX) in treating post-operative recurrence of Crohn's disease (a comparative analysis of efficacy and safety). Methods: From the 267 patients treated with adalimumab or infliximab between January 2005 and June 2014 in Romania, 44 received anti-TNF (tumor necrosis factor) therapy for prevention of post-operative recurrence. A comparison between patients treated with IFX and ADA was made with the Chi-square and t-student test, with the aid of the statistical program Mini Tab 17. Results: Twenty-one patients received IFX and 23 ADA. This included 49% males (22/44), with a mean age of 41 years, mean disease duration of 6 years, and 84.1% had previously received azathioprine. The IFX group is comparable with the ADA group regarding most of the parameters, except for therapy duration. Mean duration of therapy was 33 months. The rate of complete response was comparable between the two groups: 67% in the IFX group vs. 78.3% in the ADA group, the same as the rate of re-resection, 19.1% vs. 4.4% and the rate of endoscopic recurrence, 29 vs. 33% at 12 months. Risk factors for postoperative recurrence (POR) (male sex, younger age, ileocolonic location, stricturing or penetrating behaviour) were studied, only ileocolonic location was found to be associated with Crohn's disease recurrence in patients treated with ADA. Conclusions: Overall infliximab and aalimumab are equally efficient in patients with resected Crohn's disease (CD) with a complete response of 72.7%, a rate of re-resection of 11.4% and a rate of endoscopic recurrence of 35%. Ileocolonic location might be a predictive factor for loss of response to adalimumab in resected Crohn's disease patients.

Introduction: Entecavir (ETV) is a potent inhibitor of hepatitis B virus (HBV) replication. In patients adherent to treatment, virologic remission rates of > 95 % can be maintained with entecavir at 3-5 years Aim and methods: A cohort study was performed, including all subjects who received ETV for chronic hepatitis B, in the South-Eastern Romania. We assessed viral response, HBeAg loss and seroconversion, HBsAg loss and seroconversion, biochemical response. Comparison of categorical data was performed by χ2-test or Fisher's exact where applicable. Results: Data from 533 patients were available: predominantly males (64 %), 82.6 % nucleotide naive, 23.1 % HBe-Ag positive, 78.2 % with elevated ALT, 8 % with cirrhosis. The median follow-up was 24 months (range 12-48 months). Rate of undetectable HBV DNA increased constantly from year 1 to 3, reaching 91.2 %. Positive predictive factors for virologic response were low score of fibrosis (p-0.006), low level of HBV DNA (p-0.003), while negative predictive factors were: HBe antigen positive status (p-value < 0.001), prior IFN therapy (p 0.015). Virologic rebound was found in 7.8 % (breakthrough in 0.8 %). Rate of HBe Ag loss increases with the therapy duration, reaching 47.83 % in year 3,with two positive predictive factors: Male sex (p = 0.007), and undetectable HBV DNA at 24 weeks (p = 0.002). The percentage of HBs Ag loss was 1.31 %. Conclusions: ETV maintained and even increased the high initial response rate (from 78 % to 91.2 %). Low score of fibrosis, low level of HBV DNA, HBe antigen negative status, absence of prior interferon therapy predict a good virologic response. Virologic rebound was found in a higher rate in our population, due probably to a poor drug compliance. Lamivudine-resistant patients usually respond well to ETV, but 15.62 % are non-responders, suspect of Entecavir resistance.

Background and aims: the diagnosis of celiac disease requires small bowel biopsies to identify the characteristic mucosal changes. The current biopsy practice among endoscopists for celiac disease is in most part unknown. The aim of this study was to compare the different diagnostic policies in various centers in their current practice. Method: information from a total of 931 confirmed celiac disease patients was retrospectively obtained retrospectively from nine centers in European and Middle Eastern countries. The number of small-bowel biopsies obtained from the duodenal bulb and the second part of the duodenum was compared among different centers. Results: the most frequent stage of mucosal changes amongst Iranian subjects was Marsh IIIa whereas in the rest of the study population was Marsh IIIc. Marsh I and Marsh II were more prevalent in adults (P < 0.05) and Marsh IIIc was significantly higher in pediatric ages between 1 and 15 (P < 0.05). The most common number of biopsy specimens obtained from Romanian subjects was 1 (52% of cases), followed by 2 for Iranian (56%), 3 for Lithuanian (66.7%) and British patients (65%) and 4 for Italian patients (48.3%). For majority of cases, anemia was the most prevalent symptom (18.7%) followed by malabsorption (10.5%), diarrhea (9.3%) and dyspepsia (8.2%), respectively. Conclusions: despite the evidence-based recommendations, this study revealed a poor compliance with major guidelines on diagnosis of celiac disease. We emphasize that taking adequate number of duodenal biopsies should be implemented for an accurate diagnosis and also for the exclusion of celiac disease.
