To assess percentages of hepatitis C virus (HCV) genotypes in infected Lebanese patients referred to St. George Hospital, Beirut, Lebanon, 77 infected cases were studied. Of those, 27 were hemodialysis patients. Genotyping was performed by nested PCR of the HCV core-region with specific primers, followed by DNA enzyme-immunoassay using HCV type and subtype-specific probes. Single genotype infections were detected in 52 patients (67.5%). In these cases, types 1, 2, 3 and 4 were detected in 19.5%, 32.5%, 5.1% and 10.4% of the cases respectively. Twenty-five (32.5%) samples showed mixed genotype infections. Single genotype distribution was significantly different among dialysis and non-dialysis patients. In the dialysis group, genotype 2 was predominant (80%, p < 0.001). In single HCV genotype-infected patients, subtype 1b was frequently detected in nondialysis cases (34.4%) whereas this genotype was found in only 5% of dialysis cases. Genotypes 5 and 6 were not detected in any of the cases studied. This pilot hospital-based study provides evidence for the diversity of HCV genotypes in the Lebanese population and establishes differences in distribution depending on the risk group. 相似文献

The importance of sexual transmission in the epidemiology of hepatitis G virus (HGV) and hepatitis C virus (HCV) was evaluated in two groups of HIV-1-positive Lebanese patients. Members of one group (90 patients) were HIV-1-infected via sexual route and denied intravenous drug (IVD) use, while members of the other group (28 patients) became HIV-1-infected parenterally and confessed frequent IVD use. The overall prevalence of HGV infection was relatively high in both groups and with no statistically significant difference between them (28% among IVD users vs 32% among the non-IVD users) despite the fact that non-IVD users were significantly older (32.7 +/- 1.7 years) than the IVD users (24.0 +/- 1.4 years) (P < 0.01). Conversely, there was a clear association between IVD use and HCV infection (25% for IVD users vs 7% for non-IVD users) despite the significantly lower age of the IVD users. These results point to the efficient transmission of HGV via the sexual route, while the transmission of HCV is mainly via the parenteral route. CD4+ lymphocyte counts were known on only 82 HIV1-infected patients. Although the number of HGV-RNA-positive patients (three) was small compared with anti-HGV-positive patients (24), a relationship was not found between CD4+ lymphocyte counts and the presence of HGV-RNA in the HIV-1-positive patients. The role of HGV in causing significant liver disease is still under dispute. 相似文献

In order to evaluate the prevalence of infection with the human immunodeficiency virus in Lebanon, serologic studies were performed in a group of 1406 individuals, of whom 397 belonged to high risk groups. There were 7 seropositive individuals in the high risk population. One additional patient who was known to have the acquired immunodeficiency syndrome was also positive. It appeared that among these eight persons, the virus was acquired either through sexual activity outside Lebanon or through transfusion of foreign blood products. 相似文献

Mucormycosis is a fairly rare fungal infection caused by ubiquitous fungi of the order Mucorales and primarily affects immunocompromised hosts. A series of 16 cases of invasive mucormycosis admitted to three referral centres in Beirut, Lebanon between 1981 and 1999 is described. It includes 12 patients with rhinocerebral, three with cutaneous, and one with pulmonary infection. Onset of symptoms occurred in the summer and autumn in 15 out of 16 patients, showing a statistically significant seasonal variation (P=0.007) A recent report of 19 patients from Tel Aviv describes a strikingly similar seasonal pattern. Studies on atmospheric concentration of Mucorales spores in the Eastern Mediterranean are lacking. Weather pattern analysis in Beirut revealed clustering of onset of invasive mucormycosis at the end of a dry, warm period, which begins around May and ends in October. Mucormycosis incidence appears to be seasonal in the Eastern Mediterranean. 相似文献

The limited epidemiological data in Lebanon suggest that HIV incident cases are predominantly among men who have sex with men (MSM). We assessed the prevalence of HIV and demographic correlates of condom use and HIV testing among MSM in Beirut. Respondent-driven sampling was used to recruit 213 participants for completion of a behavioral survey and an optional free rapid HIV test. Multivariate regression analysis was used to examine demographic correlates of unprotected anal sex and any history of HIV testing. Nearly half (47 %) were under age 25 years and 67 % self-identified as gay. Nearly two-thirds (64 %) reported any unprotected anal intercourse (UAI) with men in the prior 3 months, including 23 % who had unprotected anal intercourse with men whose HIV status was positive or unknown (UAIPU) to the participant. Three men (1.5 % of 198 participants tested) were HIV-positive; 62 % had any history of HIV testing prior to the study and testing was less common among those engaging in UAIPU compared to others (33 % vs. 71 %). In regression analysis, men in a relationship had higher odds of having UAI but lower odds of UAIPU and any university education was associated with having UAI; those with any prior history of HIV testing were more likely to be in a relationship and have any university education. HIV prevention efforts for MSM need to account for the influence of relationship dynamics and promotion of testing needs to target high-risk MSM. 相似文献
