BackgroundHIV/ HBV coinfected patients are at high risk of developing chronic HBV infection, liver cirrhosis and hepatocellular carcinoma. In Mozambique, where HIV prevalence is one of the highest in the world, HIV-infected patients are scarcely characterized in terms of HBV coinfection and 3TC-resistance mutations profile.MethodsTo characterize ART-naïve HIV-infected adults, with and without HBV coinfection, a cross-sectional study was conducted between May and November 2012 in two health centers from Maputo city, Mozambique. Subjects were consecutively enrolled in the study and, then, tested for hepatitis B surface antigen (HBsAg). Moreover, CD4+ T cells count, HBV DNA in plasma, HBV genotyping and 3TC-resistance mutations profile of HBV were assessed in HIV/HBV coinfected patients.ResultsIn total, 518 patients were enrolled in the study. The median age was 33 years old and 66.8% were women. The median CD4+ T cells count was 361 cells/mm3 and 47 (9.1%) were coinfected with HBV. Out of 46 coinfected patients, 24 (55.2%) had HBV DNA ≥ 20 - < 20 000 and 12 (26.1%) had HBV-DNA ≥20 000. APRI > 2.0 was reported in 4.3% of coinfected and 1.7% of monoinfected patients (p = 0.228), while FIB-4 > 3.25 was reported in 4.4% of coinfected and 1.3% of monoinfected patients (p = 0.112). Genotype A was the most frequent, identified in 25/27 (92.6%) patients, whereas genotype E was present in 2/27 (7.4%) patients. No patient had 3TC-resistance mutations.ConclusionsThis study showed that HBV coinfection was prevalent among ART-naïve HIV-infected adults in Mozambique. Overall, these data highlight the importance of screening HBV coinfection as an integrated measure of HIV routine care to improve health conditions and treatment of HIV/HBV coinfected patients.
BackgroundThe prevalence of hepatitis B virus (HBV) infection and human immunodeficiency virus (HIV) infection in Mozambique is one of the highest in the world, though in spite of this the prevalence of occult hepatitis B infection (OBI) is unknown.ObjectivesThis study was conducted with the aim to investigate the prevalence of OBI and frequency of isolated hepatitis B core antibody (anti-HBc alone) among antiretroviral (ART) naïve HIV-positive patients in Mozambique.MethodsA cross-sectional study was conducted in two health facilities within Maputo city. All ART-naive HIV seropositive patients attending outpatient clinics between June and October 2012 were consecutively enrolled. Blood samples were drawn from each participant and used for serological measurement of HBV surface antigen (HBsAg), antibodies against HBV surface antigen (anti-HBs) and antibodies against core antigen (anti-HBc) using ELISA. Quantification of HBV DNA was performed by real time PCR. A questionnaire was used to obtain demographics and clinical data.ResultsOf the 518 ART-naive HIV-positive subjects enrolled in the study, 90.9% (471/518) were HBsAg negative. Among HBsAg negative, 45.2% (213/471) had isolated anti-HBc antibodies, and the frequency of OBI among patients with anti-HBc alone was 8.3% (17/206). OBI was not correlated either with CD4+ T cells count or transaminases levels. A total of 11.8% of patients with OBI presented elevated HBV DNA level. Frequency of individuals with APRI score > 2 and FIB-4 score > 3.25 was higher in patients with OBI as compared not exposed, immune and anti-HBc alone patients.ConclusionOur data demonstrate for the first time that OBI is prevalent among HIV patients in Mozambique, and will be missed using the commonly available serological assays that measures HBsAg.
Patient: Female, 18Final Diagnosis: Simultanous presentation of Kaposi Sarcoma and LymphomaSymptoms: —Medication: —Clinical Procedure: —Specialty: OncologyObjectiveRare diseaseBackground:KSHV/HHV-8 is associated with Kaposi’s sarcoma (KS) as well as with a few categories of lymphoproliferative diseases, mostly occurring in patients with HIV infection/AIDS. Although the association between lymphomas and Kaposi’s sarcoma has been described, the simultaneous presence of the 2 entities within the same organ is rare and mainly associated with HIV/ AIDS.Case Report:We report a case of simultaneous occurrence of Kaposi‘s sarcoma and large B-cell lymphoma in the same lymph node in a 18-year-old African woman who was HIV-negative. We found concurrent infection with Kaposi’s sarcoma herpes virus (KSHV) and Epstein-Barr virus (EBV), confirmed by PCR amplification of DNA obtained from distinct tumor areas selected in the paraffin block.Conclusions:The possibility of occurrence of 2 lesions with distinct features in the same organ may be unexpected for pathologists performing fine-needle aspiration cytology (FNAC) evaluation but must be considered, even in HIV-negative individuals, despite its rare occurrence, as was demonstrated by this case.
