HLA Genotyping in Romanian Adult Patients with Celiac Disease, their First-degree Relatives and Healthy Persons.

BACKGROUND AND AIMS: Celiac disease is characterized by an inappropriate T-cell-mediated response to gluten in small bowel in genetically predisposed individuals, carriers of the DQ2 and/or DQ8 haplotypes of the human leukocyte antigen. The aim of our study was to asses HLA typing in adult patients with celiac disease, in their first degree relatives and in a healthy control group. METHODS: We conducted a prospective observational study on three cohorts: 117 patients diagnosed with celiac disease, 41 first-degree relatives of celiac patients and 57 asymptomatic healthy volunteers. Low resolution HLA typing for DQ alleles was performed in all study subjects with DNA extracted from peripheral blood, using SSP HLA-DQB1 kit (Innotrain Diagnostik GmbH, Germany).  Next Generation Sequencing (NGS) was used only in 18 patients for typing confirmation of DQB1 and DQA1 loci and whole gene sequencing. RESULTS: Prevalence of HLA-DQ2 was significantly higher in the CD group compared to the healthy subjects group (95.6% vs 29.8%, p <0.001), with no statistically significant differences in HLA-DQ8 and combined HLA-DQ2/DQ8 prevalences.Several HLA DQA1 and DQB1 alleles (HLA-DQA1* 05:01, HLA-DQB1*02:01, HLA-DQB1*02:02) and haplotypes (DQA1*02:01-DQB1*02:02,DQA1*05:01-DQB1*02:01) were strongly associated with celiac disease in our group: OR 4.28, 4.28, 4.67 and 5.43 and 4.28 respectively. Predominantly, patients presented with typical symptoms and iron deficiency anemia. 95.5% of them had histological Marsh type modifications ≥3a. A relatively poor response to gluten-free diet was observed and 9.4% developed complications (refractory celiac disease, enteropathy-associated T cell lymphoma, intestinal adenocarcinoma), with a death rate of 6.8%. 23% associated other autoimmune diseases.Screening adherence for 1st degree relatives was very low: only 16%. Familial screening diagnosed 4 cases of asymptomatic celiac disease. 32 relatives (78%) had HLA-DQ2 haplotype, 5 carried HLA-DQ8, 4 didn't carry any risk haplotype. CONCLUSIONS: This study demonstrated a higher prevalence of the HLA-DQ2 genotype in patients with celiac disease compared to the healthy population but not of HLA-DQ8 or combined HLA-DQ2/DQ8. Alleles HLA-DQA1* 05:01, HLA-DQB1*02:01, HLA-DQB1*02:02 and haplotypes (DQA1*02:01-DQB1*02:02,DQA1*05:01-DQB1*02:01) were strongly associated with celiac disease in our cohort.

Efficacy and Safety of Ledispavir/Sofosbuvir with or without Ribavirin in patients with Decompensated Liver Cirrhosis and Hepatitis C Infection: a Cohort Study.

BACKGROUND AND AIMS: Ledipasvir/Sofosbuvir (LDV/SOF) with or without Ribavirin (RBV) has shown good results in terms of efficacy and safety in clinical trials in advanced liver cirrhosis, but real-life data are still needed in order to confirm this profile. We investigated the efficacy and safety of LDV/SOF in a large Romanian population with liver cirrhosis and genotype 1b hepatitis C virus (HCV). METHODS: We analyzed a multicentric retrospective cohort enrolling 349 patients with decompensated liver cirrhosis due to HCV who received LDV/SOF±RBV 12/24 weeks (301/48). Patients were included between 2017-2018, all with genotype 1b. Main inclusion criteria were liver cirrhosis and detectable HCV RNA. The cases were followed-up monthly during therapy and 12 weeks after the end of therapy. RESULTS: The cohort included 60% females with a median age of 61, 16% interferon (IFN) pre-treated, 53% with comorbidities, 40/53/7 % with Child Pugh A/B/C, 4% with virus B co-infection and 8% with previously treated hepatocellular carcinoma. Mean initial MELD score was 11.92 (6.82÷ 24.5). Six patients were lost during follow-up. Sustained virologic response (SVR) in intention-to-treat was reported in 85.1%. Predictive factors of SVR in decompensated cirrhosis were female gender (p=0.01), advanced age (p<0.001), lower bilirubin levels (p=0.002) and lower CTP score (p=0.02). In patients with CTP score B or C low bilirubin levels (p=0.003), low INR (p<0.001), increased platelet count (p=0.04), low CTP score (p<0.001), lack of encephalopathy (p=0.02), serum albumin >3.5g/dl (p=0.002) predicted improvement of liver function. Serious adverse events were reported in 16/349 (4.6%), most of them due to severe liver decompensation (9/16). CONCLUSIONS: LDV/SOF±RBV proved to be highly efficient in our difficult to treat population with 85.1% SVR.

Signification of Serum Alpha-Fetoprotein Levels in Cases of Compensated Cirrhosis and Hepatitis C Virus without Hepatocellular Carcinoma.

AFP (alpha-fetoprotein) levels are increased during the development of HCC (hepatocellular carcinoma); nonetheless, it can also be produced by non-tumoral hepatocytes in conditions of high cell turnover. Our study aims to provide additional data regarding the causes of elevated AFP in patients with liver cirrhosis due to hepatitis C virus (HCV) infection. We conducted an observational prospective cohort study that included 2068 patients with compensated cirrhosis and chronic hepatitis C genotype 1b infection. The two main inclusion criteria were the presence of advanced liver fibrosis - Metavir stage F4 - diagnosed by FibroMax testing, Fibroscan or liver biopsy, and the presence of detectable HCV RNA in the serum. Plasmatic AFP levels were determined through the electrochemiluminescence method, with a standard value ranging from 0 to 7 ng/ml. All data were obtained from the Romanian National Health Agency. The average AFP serum levels in patients with compensated cirrhosis without HCC were 9.4 ng/ml (range 0.5 ÷ 406 ng/ml); 30.1% of patients had significantly increased levels of AFP (>15 ng/ml). High values of serum AFP in patients with compensated liver cirrhosis without HCC was correlated with more advanced age (p<0.001), severe necroinflammatory activity detected by FibroMax (p<0.001), severe NASH (p<0.001), severe steatosis (p<0.001), low platelets (p<0.001), increased values of AST and ALT (p<0.001).
