ABSTRACT

OBJECTIVE: To determine herpes simplex virus (HSV)-2 and HSV-1 seroprevalence in women and men in Romania. METHODS: A cross-sectional seroprevalence survey was conducted between 2004 and 2005 on a total of 1058 women and men representative of the population of Bucharest. All participants were aged 15-44 years and completed a structured questionnaire. A blood sample was collected to detect IgG anti-HSV-1 and HSV-2 serum antibodies using the HerpeSelect ELISA (Focus Diagnostics). RESULTS: A total of 761 women (median age 29 years) and 297 men (median age 29 years) were included. Overall, HSV-2 seroprevalence (15.2%) increased with age. Among women, HSV-2 seroprevalence increased from 11.0% in 15-19-year-olds to 38.3% in 40-44-year-olds. Among men, seroprevalence increased from 4.0% in 20-24-year-olds to 27.1% in 40-44-year-olds. HSV-2 seroprevalence was significantly higher among women than men (17.0% vs. 10.8%). HSV-1 seropositivity was high (87.2%) in all age groups, with no clear trend by age or by sex. In addition to older age and female sex, risk factors for HSV-2 included greater number of lifetime sexual partners, lower educational attainment, and history of genital vesicles. Lower educational level and rural residence were associated with a higher risk of HSV-1 seropositivity. CONCLUSIONS: In Romania, HSV-2 seroprevalence was higher in women than men, and was within European limits and lower than that in Africa and the USA. In contrast, HSV-1 seroprevalence was generally higher than that previously recorded in similarly aged populations in Western Europe.

ABSTRACT

UNLABELLED: THE AIMS OF THE STUDY: Evaluation of the prevalence of HBV, HCV, HDV infection in patients with chronic lymphoproliferative diseases (CL), identification of the most involved viral genotypes, correlation between viremia dynamics and CL evolution, detection of molecular mechanisms implicated in CL pathogenesis, identification of lymphocytic receptors for viral antigens and biologic markers for early diagnosis of CL. METHODS: We present preliminary results of the first year of our research grant. This is a prospective, analytic, observational study in patients diagnosed with CL and HBV, HCV, HDV chronic infection. We included the following forms of CL: non-Hodgkin malignant lymphoma (NHL), Hodgkin lymphoma (HL) and chronic lymphocytic leukemia (CLL). We used the following commercial test kits: HCV RNA Real time PCR on a COBAS TaqMan (Roche Diagnostics) analyzer with 28 to 140.000.000 UI/ml detection range for HCV viremia, HBV DNA Real time PCR on a COBAS TaqMan (Roche Diagnostics) analyzer with 6 to 110.000.000 UI/ml detection range for HBV and the Roboscreen-RoboGene AJ kit with 10-10.000.000 replica/ml detection range for HDV. RESULTS: We have included 20 patients with CL and chronic hepatitis infection so far. Median age of the patients was 61 years. The identified CL forms were: B cell NHL (15 cases), T cell NHL (1 case), CLL (3 cases), Hodgkin lymphoma (1 case), equally distributed in aggressive and indolent forms of CL. HCV infection was diagnosed in 10 patients with CL, HBV infection was found in 10 patients with CL, 3 of them having co-infection HBV + HDV. In 4 patients with HBV infection viremia was over 20.000 IU/ml and the pattern of the CL was the aggressive form of the disease. The feature of the co-infection HBV + HDV was the predominance of indolent forms of CL. Among patients with HCV infection, only 3 cases were detected with viremia over 600.000 IU/ml and CL was represented by aggressive forms of the disease. We also have immunohistochemical data available in 19 cases, which seem to confirm the role of hepatitis viruses in lymphoproliferative disease etiopathogenesis. CONCLUSIONS: We ascertained an almost equally represented prevalence of HCV and HBV infection in patients with CL. The levels of HBV, HCV and HDV viremia were low in most of the cases. The most frequent form of CL was B cell NHL. We found an equal distribution between indolent and aggressive forms of NHL associated to hepatitis virus infection.
