PREVALENCE OF HYPERTENSION, ANEMIA, ASYMPTOMATIC URINARY TRACT INFECTION, SYPHILIS, HIV AND HEPATITIS B VIRUS INFECTION AMONG PREGNANT WOMEN ATTENDING AN ANTENATAL CLINIC AT A RURAL HOSPITAL IN SOUTHERN ETHIOPIA.

Antenatal care (ANC) is provided to prevent, diagnose early and treat pregnant women for a variety of diseases. The objective of this study was to determine the seroprevalences of syphilis, human immunodeficiency virus (HIV) and hepatitis B virus (HVB) and asymptomatic urinary tract infections and the prevalence of hypertension and anemia among pregnant women attending the antenatal clinic at Gambo Rural Hospital in southern Ethiopia. The following tests were conducted among study subjects: hemoglobin (Hgb) level, rapid plasma reagin (RPR) for syphilis, anti-HIV antibodies, hepatitis B surface antigen (HBsAg) and urine analysis. A total of 574 pregnant women were included in this study. The mean age of the participants was 25.7 (SD: 4.8) years old; 88.2% were living in urban areas and 11.8% in rural areas. Sixty-seven point two percent of participants began their attended care during the second trimester of their pregnancy. Overall, anemia (Hgb < 11 mg/dl) was present in 8.9% (95% CI: 6.9-11.6): severe anemia (Hgb < 7 mg/dl), moderate anemia (Hgb 7-8.9 mg/dl) and mild anemia (Hgb 9-10.9 mg/dl) were found in 0.5% (95% CI: 0.2-1.5), 0.2% (95% CI: 0.03-0.9) and 8.2% (95% CI: 6.2-10.8). The overall prevalence of hypertension was 1.2% (95% CI: 0.06-2.6). This was significantly higher (p=0.01) in the third trimester (3.2%) than in the second (0.5%) and first (0%) trimesters. The prevalence of preeclampsia, defined by have hypertension and proteinuria, was 0.7% (95% CI: 0.3-1.8). Asymptomatic urinary tract infection (having ≥10 white blood cells /high power field in the urine) was present in 12.7% of participants (95% CI: 10.0-15.5). The RPR test was positive in two patients (0.3%; 95% CI: 0.1-1.3). The prevalences of positive test for HBsAg and HIV-1 were 2.3% (95% CI: 1.3-3.8) and 0.2% (95% CI: 0.03-0.9), respectively. No HIV-2 cases were detected. Our data show relatively low prevalences of anemia, hypertension, urinary tract infection, syphilis, HIV, and hepatitis B virus infections among study subjects at a rural antenatal clinic in southern Ethiopia.

Field Evaluation of Malaria Microscopy, Rapid Malaria Tests and Loop-Mediated Isothermal Amplification in a Rural Hospital in South Western Ethiopia.

BACKGROUND: In up to one third of the hospitals in some rural areas of Africa, laboratory services in malaria diagnosis are limited to microscopy by thin film, as no capability to perform thick film exists (gold standard in terms of sensitivity for malaria diagnosis). A new rapid molecular malaria diagnostic test called Loop-mediated isothermal DNA amplification (LAMP) has been recently validated in clinical trials showing exceptional sensitivity and specificity features. It could be a reliable diagnostic tool to be implemented without special equipment or training. OBJECTIVE: The objective of this proof of concept study was to confirm the feasibility of using LAMP technique for diagnosis of malaria in a rural Ethiopian hospital with limited resources. METHODOLOGY/PRINCIPAL FINDINGS: This study was carried out in Gambo General Hospital, West Arsi Province (Ethiopia), from November 1st to December 31st 2013. A total of 162 patients with a non-focal febrile syndrome were investigated. The diagnostic capability (sensitivity, specificity, positive predictive and negative predictive values) of rapid malaria tests and microscopy by thin film was evaluated in comparison with LAMP. Eleven (6.79%) out of the 162 patients with fever and suspected malaria, tested positive for LAMP, 3 (1.85%) for rapid malaria tests and none of the eleven cases was detected by thin film microscopy. CONCLUSIONS/SIGNIFICANCE: LAMP can be performed in basic rural laboratories without the need for specialized infrastructure and it may set a reliable tool for malaria control to detect a low level parasitemia.
