Factors associated with human papillomavirus infections among women living with HIV in public health facilities in Western Oromia, Ethiopia.

BACKGROUND: Human Papillomavirus infection (HPV) is among the most common sexually transmitted infections with the highest incidence and prevalence worldwide. HPV has been established as the main cause of cervical cancer and remains a public health problem globally. In Western Oromia, Ethiopia cervical screening remains a major issue because of limited resources, and shortage of HPV testing technology. As a result, the prevalence of HPV and associated factors remain unknown among HIV-positive women. This study aimed to assess the prevalence of HPV and associated factors among women living with HIV attending Antiretroviral Therapy (ART) services in public health facilities of East Wollega and West Showa Zones, Ethiopia, 2022. METHOD: Using a cross-sectional study design, a total of 415 women ≥ 18 years old were enrolled using systematic random sampling from five public health facilities. Cervical specimens were collected by a trained nurse from April 01 2022, to May 30, 2022, and tested at Nekemte Public Health Research and Referral Molecular Biology, a certified/accredited laboratory for HPV-DNA Polymerase Chain Reaction by expertise using Abbott m2000rt-PCR assays. Finally, Epi data version 4.6 was used for data entry and SPSS version 24.0 were used for data cleaning and analysis, and frequencies and prevalence of HPV were computed. Variables were identified using the multivariable model and statistically significant associations of variables were determined based on the adjusted odds ratio (AOR) with its 95% CI and P-value < 0.05 to determine the strength of association. RESULT: The prevalence of HPV was 30.4% [95% CI: 26.0, 34.9]. Of HPV-infected women, 11.9% were positive for HPV-16, 9.5% for HPV-18, and 65.9% were positive for other hr-HPV . The odds of HPV infection among women aged beyond 48 years are 2.85 times the odds of HPV among people who were aged 18-27(AOR = 2.85, 95% CI: 1.16, 5.58). The odds of HPV infection among women who had three or more sexual partners is 4.12 times the odds of HPV infection among women with a single sexual partner(AOR = 4.12, 95% CI: 2.34-8.62). The odds of HPV infection among women who didn't use condom during sexual intercourse are 4.73 times the odds of HPV among women who used condom during sexual intercourse. (AOR = 4.73, 95% CI: 1.98-9.33). The odds of HPV infection among women who had history of is 4.52 times the odds of HPV infection among women with no history of abortion. [AOR = 4.52, 95% CI: 2.04, 6.89] The odds of HPV infection among women with history of Sexually Transmitted Infection (STI) 3.62 times the odds of HPV among women with no history of STI (AOR = 3.62, 95%CI: 1.75, 5.83). The odd of HPV among women with abnormal vaginal discharge is 3.31 times the odds of the disease among women with normal vaginal discharge [AOR = 3.31, 95% CI: 2.87,7.35). CONCLUSION AND RECOMMENDATION: The prevalence of HPV infection among HIV-infected women was high in the study area. Given the above-associated factors, we recommend that the stakeholders integrate HPV prevention strategies into HIV /AIDS services. Furthermore, the study has provided essential information about the HIV link with hr-HPV infections, which may explain the high prevalence among HIV-infected women. This can contribute to policy development and planning of prevention strategies incorporating HPV infection prevention especially among youth and HIV-infected people.

Botulism outbreak in a rural Ethiopia: a case series.

BACKGROUND: Foodborne botulism, a toxin-mediated illness caused by Clostridium botulinum, is a public health emergency. Types A, B, and E C. botulinum toxins commonly cause human disease. Outbreaks are often associated with homemade and fermented foods. Botulism is rarely reported in Africa and has never been reported in Ethiopia. CASE PRESENTATION: In March 2015, a cluster of family members from the Wollega, Oromia region, western Ethiopia presented with a symptom constellation suggestive of probable botulism. Clinical examination, epidemiologic investigation, and subsequent laboratory work identified the cause of the outbreak to be accidental ingestion of botulinum toxin in a traditional chili condiment called "Kochi-kocha," cheese, and clarified butter. Ten out of the fourteen family members who consumed the contaminated products had botulism (attack rate 71.4%) and five died (case fatality rate of 50%). Three of the patients were hospitalized, they presented with altered mental status (n = 2), profound neck and truncal weakness (n = 3), and intact extremity strength despite hyporeflexia (n = 3). The remnant food sample showed botulinum toxin type A with mouse bioassay and C. botulinum type A with culture. Blood drawn on day three of illness from 2/3 (66%) cases was positive for botulinum toxin type-A. Additionally, one of these two cases also had C. botulinum type A cultured from a stool specimen. Two of the cases received Botulism antitoxin (BAT). CONCLUSION: These are the first confirmed cases of botulism in Ethiopia. The disease occurred due to the consumption of commonly consumed homemade foods. Definite diagnoses of botulism cases are challenging, and detailed epidemiologic and laboratory investigations were critical to the identification of this case series. Improved awareness of botulism risk and improved food preparation and storage may prevent future illnesses. The mortality rate of botulism in resource-limited settings remains high. Countries should make a concerted effort to stockpile antitoxin as that is the easiest and quickest intervention after outbreak detection.

The performance of COVID-19 Surveillance System as timely containment strategy in Western Oromia, Ethiopia.

BACKGROUND: COVID-19 has been swiftly spreading throughout the world ever since it emerged in Wuhan, China, in late December 2019. Case detection and contact identification remain the key surveillance objectives for effective containment of the pandemic. This study was aimed at assessing performance of surveillance in early containment of COVID 19 in Western Oromia, Ethiopia. METHODS: A cross-sectional study was conducted from August 1 to September 30, 2020, in the 7 kebeles of Nekemte and 2 kebeles of Shambu Town. Residents who lived there for at least the past six months were considered eligible for this study. Data were collected from community and health system at different levels using semi structured questionnaire and checklist, respectively. Participants' health facility usage (dependent variable) and perceived risk, awareness, Socioeconomic Status, and practices (independent variable) were assessed. Bivariable analysis was computed to test the presence of an association between dependent and independent variables. Independent predictors were identified on multivariable logistic regression using a p-value of (<0.05) significance level. We have checked the model goodness of fit test by Hosmer-lemeshow test. RESULTS: One hundred seventy-nine (41%) of the participants believe that they have a high risk of contracting COVID-19 and 127 (29%) of them reported they have been visited by health extension worker. One hundred ninety-seven (45.2%) reported that they were not using health facilities for routine services during this pandemic. Except one hospital, all health facilities (92%) were using updated case definition. Three (33%) of the assessed health posts didn't have community volunteers. On multivariable logistic regression analysis, the source of income AOR=0.30, 95% CI (0.11, 0.86), perceived level of risk AOR=3.42, 95% CI (2.04, 5.7) and not visited by health extension workers AOR=0.46, 95% CI (0.29, 0.74) were found to be independent predictors of not using health facilities during this pandemic. CONCLUSION: Event based surveillance, both at community and health facility level, was not performing optimally in identifying potential suspects. Therefore, for effective early containment of epidemic, it is critical to strengthen event based surveillance and make use of surveillance data for tailored intervention in settings where mass testing is not feasible.

Field assessment of dried Plasmodium falciparum samples for malaria rapid diagnostic test quality control and proficiency testing in Ethiopia.

BACKGROUND: Rapid diagnostic tests (RDTs) are now widely used for laboratory confirmation of suspected malaria cases to comply with the World Health Organization recommendation for universal testing before treatment. However, many malaria programmes lack quality control (QC) processes to assess RDT use under field conditions. Prior research showed the feasibility of using the dried tube specimen (DTS) method for preserving Plasmodium falciparum parasites for use as QC samples for RDTs. This study focused on the use of DTS for RDT QC and proficiency testing under field conditions. METHODS: DTS were prepared using cultured P. falciparum at densities of 500 and 1,000 parasites/µL; 50 µL aliquots of these along with parasite negative human blood controls (0 parasites/µL) were air-dried in specimen tubes and reactivity verified after rehydration. The DTS were used in a field study in the Oromia Region of Ethiopia. Replicate DTS samples containing 0, 500 and 1,000 parasites/µL were stored at 4°C at a reference laboratory and at ambient temperatures at two nearby health facilities. At weeks 0, 4, 8, 12, 16, 20, and 24, the DTS were rehydrated and tested on RDTs stored under manufacturer-recommended temperatures at the RL and on RDTs stored under site-specific conditions at the two health facilities. Reactivity of DTS stored at 4°C at the reference laboratory on RDTs stored at the reference laboratory was considered the gold standard for assessing DTS stability. A proficiency-testing panel consisting of one negative and three positive samples, monitored with a checklist was administered at weeks 12 and 24. RESULTS: At all the seven time points, DTS stored at both the reference laboratory and health facility were reactive on RDTs stored under the recommended temperature and under field conditions, and the DTS without malaria parasites were negative. At the reference laboratory and one health facility, a 500 parasites/µL DTS from the proficiency panel was falsely reported as negative at week 24 due to errors in interpreting faint test lines. CONCLUSIONS: The DTS method can be used under field conditions to supplement other RDT QC methods and health worker proficiency in Ethiopia and possibly other malaria-endemic countries.

Magnitude of hypertension and its association with obesity among employees of Wallaga University, Ethiopia: a cross-sectional study.

OBJECTIVE: To determine the magnitude of hypertension, its association with obesity and the associated factors among employees of Wallaga University, Ethiopia. DESIGN, SETTING AND PARTICIPANTS: This institution-based cross-sectional study was employed among 588 employees of the university. Respondents were selected by stratified random sampling technique and interviewed with the aid of a structured questionnaire. THE MAIN OUTCOME MEASURED: Hypertension and obesity were measured using WHO Stepwise approach and recommendations. We used a stratified random sampling technique to select 588 employees of the university from 3 August 2021 to 15 October 2021. A structured questionnaire and anthropometric measurements were used for data collection. Multivariable logistic regression analysis was used to determine factors independently associated with hypertension. A p value less than or equal to 0.05 and its 95% confidence level was used to declare the statistical significance. RESULTS: A total of 578 participants consented and completed the study, giving a response rate of 98.3%. The mean age of the respondents was 31.78 years with SD of 5.4. The overall prevalence of hypertension, general obesity and central obesity was 14.4% (95% CI 11.6% to 17.5%), 31.3% (95% CI 27.6% to 35.3%) and 37% (95% CI 33.1% to 41.1%), respectively. Obesity was significantly associated with hypertension (adjusted OR (AOR): 6.3; 95% CI 2.60 to 8.19). Age range from 35 to 46 (AOR 7.01; 95% CI 1.56 to 31.74), age ≥46 years (AOR 8.45; 95% CI 1.14 to 62.04), being non-academic staff (AOR 2.74; 95% CI 1.56 to 4.81), having additional income (AOR 2.48; 95% CI 1.08 to 5.70), physical inactivity (AOR 2.36; 95% CI 1.44 to 3.88) and poor practice of dietary salt consumption (AOR 1.65; 95% CI 1.01 to 2.87) were factors associated with hypertension. CONCLUSION: One in seven, more than two in seven and nearly two in six of the employees of Wallaga University were hypertensive, centrally obese and generally obese, respectively. There was a positive association between obesity and hypertension. Comprehensive awareness creation and devising workplace intervention strategies are highly recommended to reduce the hypertension burden and associated obesity.

Evaluation of the performance of Panbio™ COVID-19 antigen rapid diagnostic test for the detection of SARS-CoV-2 in suspected patients in Ethiopia.

Objective: Reverse transcription-polymerase chain reaction is a gold standard diagnostic tool for coronavirus disease-2019. Limited coverage and long turnaround times are linked to the poor response to the pandemic in developing countries like Ethiopia. To overcome the challenges, rapid antigen diagnostic kits are recommended if their diagnostic performance is at an acceptable level. We explored the performance of the Panbio™ coronavirus disease-2019 antigen rapid diagnostic test in diagnosing the coronavirus disease-2019 infection. Methods: A cross-sectional study was conducted on coronavirus disease-2019 suspected patients in Wollega University Referral Hospital, from 1 April to 30 May 2021. After obtaining consent/ assent, sociodemographic and pair of nasopharyngeal samples were collected from each and examined by Panbio antigen rapid diagnostic test and reverse transcription-polymerase chain reaction. Data were entered and analysed using SPSS version 24. Sensitivity, specificity, positive and negative predictive values, and kappa values were calculated. Results: A total of 148 coronavirus disease-2019 suspected individuals (54.1% male) participated in the study. Of all, 73 (49.3%) were positive for severe acute respiratory syndrome corona virus by reverse transcription-polymerase chain reaction test. The sensitivity and specificity of Panbio were found 81% (95% confidence interval: 71%-91%) and 98.7% (95% confidence interval: 96%-100%), respectively. From 75 negative and 73 positive samples by reverse transcription-polymerase chain reaction, 1 (1.33%) and 14 (19.18%) were found false positive and negative by antigen rapid diagnostic test, respectively. Positive predictive value and negative predictive value of Panbio were 98.3% and 84.1%, respectively, and test agreement was substantial (kappa value = 0.80). Conclusion: Panbio has fine performance in suspected patients. Further studies are needed to examine the accuracy of self-collecting and patient self-testing with healthcare workers, using antigen rapid diagnostic test against the reference standard.

Prevalence of asymptomatic malaria and associated factors in Ethiopia: Systematic review and meta-analysis.

Active detection of asymptomatic malaria cases and resolution of associated factors are essential for malaria elimination. There are no nationwide estimates for asymptomatic malaria and associated factors in Ethiopia. Therefore, this study aims to generate comprehensive and conclusive evidence from various studies conducted in Ethiopia. Published articles from various electronic databases such as PubMed, Google Scholar, CINAHL, Scopes, Cochrane Library, the Web of Science, and African Journals Online were accessed. Also, unpublished studies from Addis Ababa digital library were identified. All observational study designs were included in the search. Data were extracted on the Microsoft Excel spreadsheet and analyzed using STATA version 14.1. A random-effects model was fitted to estimate the pooled prevalence of asymptomatic malaria. A meta-regression and subgroup analysis was computed to see heterogeneity. The publication bias was assessed by the funnel plots and Egger's statistical tests. The analysis found that the pooled burden of asymptomatic malaria was 6.7 (95% confidence interval = 4.60, 8.79). The pooled prevalence of Plasmodium falciparum was 3.75 (95% confidence interval = 2.25, 5.18), and that of Plasmodium vivax was 2.22 (95% confidence interval = 1.46, 2.99). Factors such indoor residual spray service (odds ratio = 0.46; 95% confidence interval = 0.26, 0.81), never used insecticide-treated nets (odds ratio = 6.36; 95% confidence interval = 4.01, 10.09), and presence of stagnant water in the vicinity (odds ratio = 3.24; 95% confidence interval = 1.20, 8.71) were found to have a significant association with asymptomatic malaria. This study highlighted that pooled prevalence of asymptomatic malaria is high and varied by population groups. Prevalence of asymptomatic malaria was increased among those who never used insecticide-treated nets and were living near stagnant water by six and three times, respectively. The use of more sensitive diagnostic methods could yield a higher burden of the disease. Furthermore, active case detection is recommended for effective intervention toward elimination.

HIV sero-status disclosure and associated factors among HIV positive women in East Africa: Systematic review and meta-analysis. Implications for prevention of mother-to-child HIV transmission.

Background: Women's HIV-positive disclosure plays a pivotal role to achieve the goal of preventing mother-to-child transmission (PMTCT) among pregnant women in particular. Although several primary studies were conducted in the different countries of East Africa, no study concluded the prevalence of women's HIV status disclosure and associated factors in East Africa. Therefore, the current study aimed to assess the pooled prevalence of disclosure status and associated factors among women in East Africa. Objectives: To assess the pooled prevalence of HIV sero-status disclosure and associated factors among women in East Africa. Methods: HINARI, PubMed, and Cochrane Library databases were searched. The data were extracted using a Microsoft Excel spreadsheet and STATA v 14.1 was used for the analysis. The Funnel plots and Egger's statistical test was used to check publication bias. Heterogeneity was assessed by conducting sensitivity and subgroup analyses. Result: The pooled prevalence of sero-status disclosure among women in East Africa was 73.77% (95%CI 67.76, 79.77). Knowing partner's sero-status (OR = 10.04(95%CI 3.36, 31.84), married (OR = 2.46 (95%CI 1.23, 4.89), smooth relationship (OR = 3.30 (95%CI 1.39, 7.84), and discussion on HIV before the test (OR = 6.96 (95%CI 3.21, 15.05) were identified determinants of HIV sero-status disclosure. Conclusion: The current systematic and meta-analysis revealed that nearly one-fourth of women had not disclosed HIV sero-status to at least one individual. Knowing the partner's HIV sero-status, being married, having a smooth relationship, and discussing on HIV before the test were determinants of disclosure status. Therefore, disclosure of HIV-positive sero-status among women living with HIV needs to be strengthened.

Seroprevalence of Hepatitis B Virus and Associated Factors among Pregnant Women Attending Antenatal Care Services at Public Health Facilities in Nekemte Town.

BACKGROUND: Viral hepatitis is an emerging global health problem. A pregnant mother infected with the hepatitis B virus has a high rate of vertical transmission, causing adverse fetal and neonatal outcomes. Understanding the magnitude of the problem and associated factors has paramount importance to avert such adverse fetal and neonatal outcomes. Therefore, the main aim of this study was to assess the seroprevalence of hepatitis B virus and associated factors among pregnant women attending antenatal care clinics at public health facilities in Nekemte town. METHODS: An institutional-based cross-sectional study was conducted among 277 pregnant women attending antenatal care at public health facilities in Nekemte town from June 1 to July 30, 2020. All public health institutions in Nekemte town (two hospitals and one health center) were recruited, and study participants were selected by using a systematic sampling method. The data were collected using pretested and structured questionnaires using a face-to-face interview, and a blood sample was collected to test for hepatitis B surface antigen. Logistic regression analysis was employed to identify factors significantly associated with hepatitis B virus infection. Variables with a p value < 0.05 were considered statistically significant predictors of the outcome variable. RESULT: The overall seroprevalence of hepatitis B virus infection was 16 (5.8%) [95% CI: 3.2-8.7], which indicates intermediate endemicity. History of abortion (AOR =6.155; 95% CI: 1.780, 21.291), history of contact with hepatitis patient (AOR =7.178; 95% CI: 1.702, 30.279), and having multiple sexual partners (AOR =6.788; 95% CI: 1.701, 27.086) had a statistically significant association with hepatitis B surface antigen seropositivity. CONCLUSION: Hepatitis B virus seroprevalence among pregnant women in this study shows intermediate endemicity. Therefore, health professionals should provide health information on the risk of having multiple sexual partners, risk factors of unprotected contact with hepatitis patients, and abortion for pregnant women during their antenatal care visits.
