The aim of this study was to evaluate the association between the HLA-G 14-bp deletion/insertion (Del/Ins) polymorphism and soluble (s) HLA-G production in patients with Crohn's disease (CD). We analyzed also the sHLA-G molecules by ELISA and western blot in plasma samples. Among unselected patients, the 14-bp Del/Ins polymorphism was not significantly associated with increased CD risk neither for alleles (P = 0.371) nor for genotypes (P = 0.625). However, a significant association was reported between the 14-bp Del/Ins polymorphism and CD, in particular in young-onset CD patients for alleles [P = 0.020, odds ratio (OR) = 2.438, 95% confidence interval (CI): 1.13-5.25] but not with adult-onset CD patients. A significant association was reported concerning the genotype Ins/Ins for young-onset CD patients (P = 0.029, OR = 3.257, 95% CI: 1.08-9.77). We observed also a significant increase in sHLA-G measured by ELISA in CD patients compared to controls (P = 0.002). The 14-bp Del/Del and 14-bp Del/Ins genotypes are the high HLA-G producers. Among sHLA-G(positive) patients, 43% of subjects present dimers of HLA-G. The presence of dimers seems to be related to the advanced stages of the disease. The 14-bp Del/Ins polymorphism is associated with an increased risk of CD particularly in young-onset CD patients and controls sHLA-G plasma levels. Dimers of sHLA-G are frequent in advanced disease stages. The above findings indicate that the genetic 14-bp Del/Ins polymorphism in exon 8 of the HLA-G gene is associated with the risk of CD and suggest a role for sHLA-G as a prognostic marker for progressive disease.

Sarcoidosis is a systemic non caseous granulomas disease. Liver is a common location but usually asymptomatic. Evidence based guidelines for this location treatment is lacking and the effect of corticosteroids may be inadequate. The aim of our study was to describe the clinical, biochemical, radiological and therapeutic features of seven patients with systemic sarcoidosis and liver involvement. A retrospective and descriptive monocentric study, over 3 years, including seven patients with systemic sarcoidosis and liver involvement. We included 5 women and 2 men with an average age of 43 years. Hepatic localization revealed sarcoidosis in 5 cases. Hepatomegaly was observed in all patients as well as abnormal serum liver function test reflected by anicteric cholestasis. Liver biopsy, showed in all granulomatous lesions consistent with sarcoidosis and severe fibrosis in 2 cases. Extra-hepatic manifestations were present in all patients represented mainly by pulmonary location. All patients were treated, five by corticosteroid and two with ursodeoxycholic acid (UDCA). Complete response was observed in one case, partial response in another case and corticosteroid refractoriness in one case. In two cases, corticosteroid therapy was introduced for less than 1 month, not allowing assessment of response. Antimalarials in combination with UDCA were used successfully in a patient with steroid-resistant liver disease. Liver involvement can reveal systemic sarcoidois. Given the risk of progression to severe liver disease, it must be screened in all patients with systemic sarcoidosis. Treatment is not systematic, and still based on corticosteroid therapy. In the absence of prospective randomized controlled trials, the efficacy of UDCA need to be proven.

Hepatitis C virus (HCV) infection is a major public health concern worldwide, raising important medical and economic issues. HCV-related end-stage liver disease is one of the most common indications for hepatic transplantation. Chronic hepatitis C is also assimilated to a systemic disease because of multiple extrahepatic manifestations, including lymphoproliferative disorders. The revolution of HCV treatment with the advent of direct-acting antivirals has significantly improved the management with high antiviral efficacy and good safety profile compared with old regimens, thus allowing good outcomes on hepatic and extrahepatic symptoms. However, with the widespread use of these new agents, controversial concerns about unexpected increasing cases of hepatocellular carcinoma were reported. We now report the case of a patient presenting with HCV-related cirrhosis, treated with direct-antiviral therapy and diagnosed with primary hepatic lymphoma shortly after the end of the treatment.

AimTo evaluate the impact of the perception of body image on sexual activity of obese patients compared to a sample from the general population.Patients and methodsA cross-sectional case-control study. It involved 40 obese married patients (BMI ≥ 30 kg/m2) and 40 normal weight subjects of the general population. A questionnaire was presented with sociodemographic data, somatic and psychiatric personal histories and data on obesity. Besides, there were seven items assessing perception of body image and five items assessing the impact on sexuality.ResultsThe sex-ratio (men/women) of obese patients was 0.53. Obese women were less frequently satisfied with their body image than men (p = 0.002). Obese subjects were statistically more dissatisfied with their bodies than controls (p = 0.039). In Obese patients, avoidance of sexual intercourse was significantly related to dissatisfaction with body image (p = 0.025) and to the perception of unattractive body (p = 0.026). Sexual satisfaction was statistically correlated with the perception of a positive attracting body (p = 0.015). Sexual desire was statistically correlated to the satisfaction of body image (p = 0.019), positive perception of an attractive body (p = 0.017) and positive perception of a youthful body (p = 0.041). Sexual pleasure was correlated with the perception of an attractive body (p = 0.016).ConclusionThe stigmatization of obese subjects leads to a weakening of the healthy perception of body and might be an obstacle to sexual fulfillment.
