Rifampicin-Resistant Multidrug-Resistant Tuberculosis Cases in Selected Hospitals in Western Oromia, Ethiopia: Cross-Sectional Retrospective Study.

PURPOSE: With the recommendation of World Health Organization (WHO) and as per the Ethiopian National Implementation Guideline, GeneXpert is used for rapid diagnosis of rifampicin (RIF)-resistant multidrug-resistant tuberculosis (MDR-TB) from the suspected TB patients; however, there were limited findings in Ethiopia particularly in the study area showing the magnitude of RIF-resistant MDR-TB and related factors among suspected TB cases. Hence, we aimed to assess resistance to RIF as a biomarker for the detection of MDR-TB cases from the suspected TB patients in selected hospitals, Western Oromia, Ethiopia. PATIENTS AND METHODS: We have conducted a cross-sectional review on 2300 registered GeneXpert data as clinically suspected TB cases in three governmental hospitals, Western Oromia, Ethiopia, between October 2015 and April 2016 to assess resistance to RIF as a biomarker for the detection of MDR-TB cases. Trained data collectors enumerated the data using pre-tested semi-structured questionnaires from the Gene Xpert records found in the registration logbook available at each hospital laboratories. Following checking the data for completeness, we have cleaned and entered our data into SPSS version 20 to compute different analyses. P-value of ≤0.05 was taken as statistically significant. RESULTS: A total of 2300 TB suspected cases were included in the study. The overall prevalence of TB diagnosed by the GeneXpert assay was 21.3% (491/2300). In all TB confirmed cases, RIF-resistant TB accounted for 25.9% (127/491) which expressed rpoB gene mutations. Sex (being male), age (within 16-30 age group), patient category (relapse, loss to follow-up, treatment failure and had MDR-TB contact) were significantly associated with rifampicin-resistant TB. Relapse patient was 20 times more likely to develop MDR-TB when compared to the new patient (P-value= 0.01, COR = 20.0, 95%C.I = 17.5-42.5). CONCLUSION: The rifampicin-resistant TB is prevalent in all age groups. The strong association and high prevalence of RIF-resistant TB to failure after treatment in this study require more attention towards improving the treatment to minimize evolving of the MDR-TB cases.

Assessment of malaria as a public health problem in and around Arjo Didhessa sugar cane plantation area, Western Ethiopia.

BACKGROUND: Although much progress has been made in reducing malaria morbidity and mortality worldwide in the last decade, nationally malaria remains the third leading cause of death and still considered a major public health problem. Therefore, this study was aimed to assess malaria as a public health problem in and around the sugar cane plantation area of Arjo Didhessa sugar factory, Western Ethiopia. METHODS: A community-based cross-sectional study supplemented with clinical retrospective data, which included 452 study subjects was recruited and the study period was extended from May 2016 up to November of 2017. A standardized questionnaire was used to assess malaria risk factors and blood samples were received from all study participants and further subjected to Giemsa staining for determination of malaria prevalence. Data were analyzed by SPSS version 20. Malaria risk factors were identified by multivariate logistic regression at a significance level of P < 0.05. RESULTS: The overall malaria prevalence was 3.1%; Plasmodium vivax is the main type of malaria parasite. Overnight outdoor sleeping and improper utilization of mosquito bed nets were found to be statistically significant as malaria risk factors in the community. In the retrospective studies of five years, the peak malaria cases (13.84%) were reported in 2013 and the lowest cases (1.24%) in 2017. CONCLUSIONS: The figure for malaria witnessed in this area remains higher than the observed national malaria prevalence indicating malaria remains a public health problem. Therefore, we suggest the factory administrators and health care professionals work more on raising awareness to avoid night outdoor sleeping and promote frequent and appropriate utilization of insecticide-treated nets in line with regular indoor residual spraying.

Prevalence of Cryptococcal Antigenemia and associated factors among HIV/AIDS patients on second-line antiretroviral therapy at two hospitals in Western Oromia, Ethiopia.

BACKGROUND: Cryptococcosis is a global public health important infectious disease. HIV infection is the main risk factor estimated to account for 95% of cases in the middle- and low-income countries and 80% of the cases in high-income countries. OBJECTIVE: The main aim of the study was to determine the prevalence and associated risk factors of Cryptococcal antigenemia (CrAg) among HIV/AIDS Patients on second-line ART Therapy at Ambo General Hospital and Nekemte Referral Hospital, Western Oromia, Ethiopia. MATERIALS AND METHODS: Hospital-based cross-sectional study was employed from September 1, 2017, to October 30, 2017. Whole blood was tested for CrAg using Cryptococcal lateral flow assay (Immuno-Mycologics, Norman, OK, USA) according to the manufacturer's instructions. The collected data were analyzed using SPSS version 20 software. Binary logistic regression models were applied to assess the association between predictors and outcome variables at 95% CI. RESULT: Among the study participants, 115(62.8%) were females and the median age of the participants was 35 (IQR: 14) years. Majority, 169(92.3%), have been living with HIV for ≥ 5.6 years and 124 (67.8%) stayed on 2nd line ART for an average of 2.5 years. The overall prevalence of Cryptococcal antigenemia in the study participants was 7.7% (14/183). Being male [AOR, 95% CI: 4.78(1.14, 20.1)], poor adherence to ART [AOR, 95% CI: 0.12(0.03, 0.4)], occupational exposures to contaminated soil [AOR, 95% CI: 6.81(1.38, 33.4)], having non-separated house from chickens [AOR, 95% CI: 0.06(0.01, 0.51)], CD4 T+ cell levels ≤ 100 cell/µL [AOR, 95% CI: 6.57(1.9, 23.3)] and viral load >1000 copies/mL [AOR, 95% CI: 11.7(2.4, 57.8)] were significant predictors of Cryptococcal antigenemia (P≤ 0.05). CONCLUSION: The prevalence of Cryptococcal Antigenemia was significantly high in this study. Being male, occupational exposure to contaminated soil with avian droppings, CD4+ T cell levels <100 cell/µL and viral load >1000 copies/mL were significant predictors of Cryptococcal antigenemia. Therefore, public health measures, adherence to ART and early treatment are recommended.

Prevalence of intestinal parasites and its risk factors among food handlers in food services in Nekemte town, west Oromia, Ethiopia.

BACKGROUND: Food-borne diseases are a public-health problem in developed and developing countries. The World Health Organization (WHO) estimated that in developed countries, up to 30% of the population suffers from food borne diseases each year and more in developing countries, where up to 2 million deaths are estimated per years. OBJECTIVE: To assess the prevalence of intestinal parasites and its associated risk factors among food handlers in Nekemte town. METHODS: A cross-sectional study was conducted in Nekemte from April to May, 2016. A total of 240 food handlers were selected using a simple random-sampling technique from hotels, bars, and restaurants. Data were collected using pretested questions and stool-specimen examination for intestinal parasites. For intestinal parasites, stool-sample examinations were done using wet-mount and concentration methods. Data analysis was done using SPSS version 20. Associations among intestinal parasites and risk factors were determined using logistic regression and P<0.05 considered significant. RESULTS: The prevalence of intestinal parasites in this study was 52.1%. Entamoeba histolytica/dispar was the most predominant parasite (56.8%), followed by Ascaris lumbricoides (26.4%), Taenia saginata (16%), and hookworm (16.8%). Hygienic practice such as hand washing after toilet by water, hand washing after toilet by water and soap, trimming of finger nail, wearing proper working clothes and shoes were statistically significant with intestinal parasitic infection if not regularly performed (P<0.05). CONCLUSION: The prevalence of intestinal parasites in this study was high, with single double, and triple infection. Food handlers should practice safe food preparation and food service to reduce the probability of intestinal parasite infection.

Prevalence of Hepatitis C Virus and HIV Infection Among Pregnant Women Attending Antenatal Care Clinic in Western Ethiopia.

Background: Hepatitis C virus (HCV) and HIV infection remain a major public health challenge in Sub-Saharan Africa. The HCV and HIV infection among pregnant women have a serious outcome on maternal and newborn health. There is limited information in this regards in West part of Ethiopia. This study aims to identify the sero- prevalence and predictor factors of HCV and HIV infection among pregnant women attending antenatal care (ANC) in Western Ethiopia. Methods: An institutional based cross-sectional study was conducted from July to September, 2014 among 421 pregnant women's attending ANC services in purposively selected health facilities of western Ethiopia. The HCV and HIV infections were diagnosed by detection antibodies from aseptically collected serum sample. HCV was identified using an enzyme linked immune sorbent assay (ELISA) while HIV infection was tested with rapid HIV tests following the national HIV test algorithm. The pretested and structured questionnaire was used to collect socio-demographic data, and potential predictor factors of HCV and HIV infection. The collected data were analyzed using SPSS version 20.0 statistical software. Result: The overall sero-prevalence of HCV and HIV among the study population was 8.1% and 1.0%, respectively. The prevalence of HCV/HIV co-infection was 0.23% (1/421). Among HIV infected women, the prevalence of HCV infection was 25% (1/4). The risk of HCV infection was significantly low for urban residents (AOR = 0.38, 95%CI: 0.16-0.90) and illiterate (AOR = 0.24, 95%CI: 0.06-0.85). However, the history of blood transfusion was significantly increases the risk of HIV infection (AOR = 19.52, 95%CI: 1.80-150.6). Conclusion: Our study confirms public health importance of HCV and HIV infections among pregnant women in the study area. The study suggests need of attention for rural residents and educated segment of the population for HCV prevention, and national blood blank to check HIV test method used for blood transfusion.

Seroepidemiology of Hepatitis B and C Virus Infections among Pregnant Women Attending Antenatal Clinic in Selected Health Facilities in East Wollega Zone, West Oromia, Ethiopia.

BACKGROUND: Hepatitis B virus and hepatitis C virus infections are a public health problem worldwide. It is highly endemic in Asia and Sub-Saharan Africa. Horizontal and perinatal transmissions are thought to be the major modes of transmission in these countries. Objective. This study aimed to investigate the seroepidemiology and possible risk factors for hepatitis B virus and hepatitis C virus infection among pregnant women attending antenatal care clinics. METHODS: A cross-sectional study design was conducted from July to September 2014 among 421 pregnant women attending antenatal care services in randomly selected health facilities, East Wollega Zone, West Oromia, Ethiopia. Blood sample was collected from each woman and separated serum was tested for the presence of markers. A prestructured questionnaire was used to collect sociodemographic data and risk factors. The collected data was analyzed using SPSS 20.0 statistical software. Odds ratio and 95% confidence interval were used as measures of the strength of association. RESULT: The overall prevalence of HBsAg was 2.4% ranging from 0.0% to 5.2%. It was the highest in Sire Health Center and the lowest/nil in others. The prevalence of HCV ranged from 6.7% to 20% with an average of 8.07% in this study area where it was highest in the Getema Health Center Antenatal Care Attendants. Only address (p=0.020) and area of the health institution (p=0.021) are significantly the associated factors for HBsAg and serostatus of HCV, respectively. CONCLUSION: The prevalence of HBsAg carrier rate of pregnant women in the study area falls within the medium endemic prevalence and HCV prevalence was higher than HBsAg. Study participants who were from urban areas were significantly affected with HBV while study institution affects the prevalence of HCV infection so that initiating screening tests during follow up period for antenatal care services is mandatory.

Factors determining late antenatal care booking and the content of care among pregnant mother attending antenatal care services in East Wollega administrative zone, West Ethiopia.

INTRODUCTION: Antenatal care (ANC) is important for both maternal and fetal health. However, the existing evidence from developing countries indicates that most pregnant women attending ANC in their late pregnancy. Little is known about the factors determining ANC booking and the content of care among pregnant women in West part of Ethiopia. Therefore, the present study was conducted to identify factors determining late ANC booking and the content of care among pregnant mother attending antenatal care services in East Wollega administrative zone, West Ethiopia. METHODS: Institutional based cross-sectional study was conducted from July to September, 2014 among 421 pregnant women's attending ANC services in purposively selected health facilities, East Wollega zone, Ethiopia. The pretested-structured questionnaires were used to collect socio-demographic data and predictor factors of late initiation of ANC services. Five trained nurse working at ANC clinic at each health institution administered the questionnaire. The collected data was analysed using SPSS version 20. RESULTS: The prevalence of late ANC booking was 81.5% (343/421) in the study area. Being from Oromo ethnic group (AOR 4.27, (95% CI, 1.48-12.33)), maternal age equal or more than 25 year old (AOR 3.09 (95% CI, 1.53-6.27)), second trimester (AOR 6.05(95% CI, 3.08-11.88)) and third trimester (AOR 7.97 (95% CI, 3.92-16.23)) were main factors identified as contributing (favoring factors) for the likely occurrence of late booking for ANC whereas; monthly income more than and/or equal to 15000 Ethiopian birrs (AOR 0.38 (95% CI, 0.18-084)) were factors compromising (decreasing) the chances for late attendance for the services among the pregnant women. CONCLUSION: Late ANC initiation is high in the study area despite the services is provided free of charge. Hence, it is important to provide health education on the timing of ANC among women with reproductive age. Community's awareness on importance of receiving early ANC also needs to be promoted.

Prevalence and drug susceptibility pattern of group B Streptococci (GBS) among pregnant women attending antenatal care (ANC) in Nekemte Referral Hospital (NRH), Nekemte, Ethiopia.

OBJECTIVE: The main objective of this study was to determine the prevalence and drug susceptibility pattern of group B Streptococci (GBS) among pregnant women. The specific objectives include; (1) To determine the prevalence of GBS colonization among pregnant women (2) To determine the drug susceptibility pattern of GBS among pregnant women and (3) To identify associated risk factors with GBS colonization among pregnant women. RESULTS: The median age of the participants was 24.5 years (range 16-38) and 86% participants were urban residents. The total prevalence of maternal GBS colonization from vaginal swab culture was 12.2% (22/180). The prevalence of GBS colonization rate was significantly higher in those pregnant women above 37 weeks of gestation [AOR, 95% CI 2.1 (1.2, 11.6), P = 0.03] and married ones [AOR, 95% CI 3.2 (1.8, 11.6), P < 0.021]. Twenty (91%) of GBS isolates were sensitive to vancomycin and the highest resistance was observed against penicillin G (77.3%). The prevalence of GBS colonization in this study was significantly high and differed by gestational age and marital status. None of the GBS isolates were resistant to vancomycin but higher resistance was shown against Penicillin G.
