Untreated highly viraemic pregnant women from Asia or sub-Saharan Africa often transmit hepatitis B virus despite serovaccination to newborns.

BACKGROUND & AIMS: Mother-to-child (MTC) hepatitis B virus (HBV) transmission has been mainly studied in Asia. The geographical origins of women and HBV genotypes differ in Europe. The aims were to determine the rate and risk factors of MTC HBV transmission from women with high HBV DNA loads in a maternity hospital in Paris, France. METHODS: Retrospective study of HIV-negative, HBs Ag-positive pregnant women with HBV DNA loads above 5 Log10 I.U/ml who were not given lamivudine or tenofovirDF during pregnancy between 2004 and 2011. RESULTS: Among 11 417 pregnant women, 437 (4%) showed a positive HBs Ag. Among these women, 52 had HBV DNA loads above 5 Log10 I.U/ml: 41, 10 and 1 born in Asia, sub-Saharan Africa and Europe respectively. Among the 52 women, 40 were eligible for the analysis: no antiviral therapy during pregnancy; children over 9 months old. Twenty-eight (70%) women were assessed, corresponding to 41 childbirths. Eleven children (27%) had positive HBs Ag, 14 (34%) had positive HBc and HBs Ab, 16 (39%) had positive HBs Ab only. The risk of having positive HBs Ag, according to maternal HBV DNA loads, was 14% for HBV DNA loads less or equal to 8 Log10 I.U/ml, 42% for HBV DNA loads over 8 Log10 I.U/ml, P = 0.04, but not related to the women's origin, HBV genotype. CONCLUSIONS: This study confirms that serovaccination does not fully protect newborns from MTC HBV transmission, when maternal HBV DNA loads exceed 5 Log10 I.U/ml, regardless of the women's origin or HBV genotype.

Hepatitis E virus infection in HIV-infected patients with elevated serum transaminases levels.

Increases in aminotransferases levels are frequently encountered in HIV-positive patients and often remain unexplained. The role in this setting and natural history of hepatitis E in HIV-infected patients are unknown. The aim of the study was to assess HEV infection in HIV-infected patients attending a Parisian hospital, with a current or previous cryptogenic hepatitis.191 plasma samples collected from 108 HIV-infected patients with elevated aminotransferases levels were retrospectively tested for the presence of hepatitis E virus (HEV) infection markers: anti-HEV IgM antibodies, anti-HEV IgG antibodies, anti-HEV IgG avidity index and plasma HEV RNA.One acute infection, documented by positive tests for anti-HEV IgM antibody, low anti-HEV IgG avidity index and plasma HEV RNA (genotype 3e), and three past infections were diagnosed, without any observed case of persistent infection. The acute hepatitis was benign and resolved spontaneously within two weeks. This infection was probably contracted locally. Acute HEV hepatitis can occur in HIV-infected patients but rarely explains cryptogenic hepatitis, at least in an urban HIV population, regardless geographic origin and CD4 counts.

[Proposal of HIV, HBV and HCV targeted screening: short period feasibility study in a free-access outpatient medical structure]. / Faisabilité du dépistage ciblé VIH, VHB, VHC dans une structure de soins ambulatoires avec un système de permanence d'accès aux soins de santé intégré

OBJECTIVES: In France, patients coming from sub-Saharan Africa, French Indies and French Guiana are frequently missed HIV, HBV and HCV diagnosis, despite high prevalence of these infections. METHODS: Targeted proposal of HIV, HBV and HCV screening, using sensitive enzyme immunoassays, to any adult patient originating of the above mentioned areas, with/without medical insurance, consulting for a medical issue in outpatients' department. Monocentric prospective study in a hospital in Paris during 28 consecutive days in 2010. RESULTS: Among the 272 eligible patients, 166 were tested (patients' acceptance: 61%). 180/272 (66%) alleged being tested previously for HIV, women (66/87, 76%) more frequently than men (114/185, 62%), P=0.02. Patients' acceptance seemed higher in patients mentioning no previous test than in patients reporting previous test. Among the patients who refused being tested, reporting a previous negative HIV test, more than a quarter has been tested more than 1 year ago. Among the 166 tested patients, 120 (72%) came back to get their results, men (89/113, 79%) more frequently than women (31/53, 58.5%), P=0.009; recently metropolitan patients more frequently than longer metropolitan patients, P=0.01; patients without any job more frequently than patients with a job, P=0.01. Three (1.8%) HIV tests returned positive; HBsAg was positive in 13 (7.8%) patients; 54 patients (32.7%) had a negative hepatitis B screening (anti-HBcAb+HBsAg+anti-HBsAb), attesting to sensitivity to this infection, only 18 patients (10.9%) showed isolated anti-HBsAb at protective levels. Eighty-one patients (49.1%) exhibited anti-HBcAb, confirming the high prevalence of HBV infection in the areas the patients came from. Six patients (3.6%) had anti-HCVAb. There was no co-infection. CONCLUSION: Targeted HIV, HBV and HCV screening to patients coming from high prevalence areas in outpatients' department appears a very cost-effective strategy.

Lymph node tuberculosis in patients from regions with varying burdens of tuberculosis and human immunodeficiency virus (HIV) infection.

BACKGROUND: Few large cohorts of patients with lymph node tuberculosis (LNTB) have been reported in developed countries. OBJECTIVE: To describe the epidemiological and clinical characteristics of LNTB in patients living in France but born and raised in geographic areas with varying burdens of tuberculosis and human immunodeficiency virus (HIV) infection. DESIGN: A retrospective study of all patients with bacteriologically-proven LNTB assessed in a French hospital from March 1996 through April 2005. RESULTS: The analysis included 92 patients. HIV coinfected patients had a higher risk than those without HIV of presenting with disseminated TB and systemic symptoms and of hospitalization. Lymph node diagnostic procedures had a high yield when samples were cultured. About 25% of patients had an abnormal chest radiograph, and most of them were positive for acid-fast bacilli on sputum smears or for Mycobacterium tuberculosis culture. Treatment was generally prescribed for a longer duration than that recommended by international guidelines. One quarter of the patients developed a paradoxical reaction. A high proportion of our patients were classified as nonadherent and 20% defaulted or were lost to follow-up. CONCLUSION: Most of the differences in the clinical presentation among patients from various geographic areas were driven by the epidemiology of TB and HIV in the countries of origin. LNTB is frequently a clinical sign of disseminated disease, and culture for M. tuberculosis from LN or other sites is crucial for diagnosis. Adopting the strategy of Directly Observed Treatment, Short course (DOTS) might reduce the rates of nonadherence and default.
