Diagnosis of Trichomonous vaginalis by microscopy, latex agglutination, diamond's media, and PCR in symptomatic women, Khartoum, Sudan.

BACKGROUND: Trichomoniasis is the most common sexually transmitted disease. However, limited data are available on an effective technique for the diagnosis of Trichomonas vaginalis. METHODS: A cross-sectional study was conducted to evaluate the accuracy of wet mount microscopy, latex agglutination, Diamond's media, and polymerase chain reaction (PCR) for detection of T. vaginalis among symptomatic women who attended the gynecological clinic at Khartoum, Sudan. RESULTS: Of the 297 women studied, 252 (84.8%) were positive for T. vaginalis by wet mount microscopy, 257 (86.5%) by latex agglutination, 253 (85.2%) by Diamond's media, and 253 (85.2%) by PCR. The sensitivity and specificity of wet mount microscopy were 99.2% and 97.7%, respectively, compared with PCR. The sensitivity and specificity of latex agglutination and Diamond's media were 99.6% and 88.6%, and 100.0% and 86.4%, respectively, compared with PCR. CONCLUSIONS: In this study, wet mount microscopy, latex agglutination, and Diamond's media were found to be highly sensitive and specific. However, the availability and cost effectiveness might limit the use of Diamond's media and PCR in routine practice.

Epidemiology of hepatitis B and hepatitis C virus infections in pregnant women in Sana'a, Yemen.

BACKGROUND: Screening for Hepatitis B and C during pregnancy may help to decide on appropriate antiviral therapy and the institution of steps to minimize vertical transmission to the newborn infants. METHODS: A cross-sectional study was conducted during November-December 2011 to investigate the seroprevalence and associated risk factors for markers of HBV (hepatitis B surface antigen; HBsAg) and anti-HCV antibody among pregnant women at the Al-Thawra hospital in Sana'a, Yemen. Structured questionnaires were used to obtain sociodemographic obstetrics and medical data and sera were tested for HBsAg and anti-HCV. RESULTS: Of the 400 pregnant women enrolled in the study, HBsAg and anti-HCV were detected in 43 (10.8%; 95% CI: 8.0-14.0%) and 34 (8.5%, 95% CI: 6.0-11.5%) women, respectively. None of the women were co-infected with HBV and HCV. Multivariate analysis showed that circumcision was significantly associated with HBsAg seropositivity (OR = 3.3, 95% CI: 1.1-10.2; p = 0.03), low parity (primigravidae and secundigravidae) and education below secondary level were significantly associated with anti- HCV seropositivity (OR = 3.3, 95% CI: 1.1-10.2; p = 0.03). No other sociodemographic or clinical characteristics (age, residence, history of home delivery, miscarriage, dental manipulation, surgery, and blood transfusion) were significantly associated with HBsAg or anti-HCV seropositivity. CONCLUSION: The results of this study suggest that HBsAg and anti-HCV have high prevalence among pregnant women.
