From Option B+ to Universal "Test and Treat" in Cameroon: Identification and Evaluation of District-level Factors Associated with Retention in Care.

Background and Objective: Retaining women in Option B+ services is crucial for eliminating new pediatric HIV infections. However, there are few studies on factors influencing retention at the district level. This study evaluates the factors associated with retention in two health districts of Cameroon. Methods: From September 1, 2015, to February 29, 2016, we reviewed the records of pregnant and breastfeeding women initiating Option B+, a lifelong approach to preventing mother-to-child transmission (PMTCT) of HIV, between October 2013 and July 2014. We abstracted sociodemographic and clinical data from registers in 22 health facilities in the Bamenda urban and Kumba rural districts into spreadsheets. Cox regression age-adjusted survival curves were used to compare retention probabilities at 6 and 12 months post-antiretroviral therapy (ART) initiation. Multivariable modified Poisson regressions were run to estimate adjusted relative risk (aRR) of factors associated with retention in PMTCT care at 12 months post-ART initiation. STATA software was used for the analyses. Results: Of the 560 files reviewed, majority, 62.7% (n=351), were above 24 years of age and married, 68.9% (n=386). From the multivariable analysis, enrolling early in antenatal care (ANC) (aRR: 1.50, 95% CIL: 1.17-1.93) and knowing the male partner's HIV-negative status (aRR: 1.16, 95% CI: 1.00-1.34) were significantly associated with higher retention in care, adjusting for maternal age, marital status, and distance from the health facility. By health district, knowing the male partner's HIV-negative status (aRR: 1.30, 95% CI: 1.13-1.50) in the Bamenda urban and enrolling early in ANC (aRR: 2.03, 95% CI" 1.21-3.41) in the Kumba rural district, had significantly higher retention rates after adjusting for the same covariates. Conclusion and Global Health Implications: Overall, factors influencing retention varied by urban or rural district. Therefore, tailored district-level interventions are needed to enhance early ANC enrollment in the rural and partner HIV status disclosure in the urban districts to improve retention in PMTCT care.

Evaluation of quality of life and associated factors among HIV patients on antiretroviral therapy in North West region of Cameroon.

BACKGROUND: There is evidence that Quality of Life (QoL) of People Living with HIV/AIDS (PLHIV) has a significant role in ART retention, treatment adherence, and survival. As a result, QoL is becoming increasingly important for policymakers, program implementers, and researchers. However, factors associated with QoL, in a culturally diverse country like Cameroon are unknown. OBJECTIVE: We aimed to assess the QoL of PLHIV on ART and assess the extent to which physical, psychosocial, environmental, and spiritual factors drive QoL. METHOD: A cross-sectional study was conducted among 394 PLHIV aged >21 in North-West Cameroon from April to July 2019. Data were collected using WHO-QOL BREF questionnaire. Descriptive statistics, bivariate, and multivariate linear regression analyses were performed. RESULTS: Majority (34.5%) of participants were in the age range of 41-50, with 73% females. The average QoL of the respondents was "good" with mean score of 3.57 on 5 and 71.4% agreed to have satisfactory QoL. Bivariate regression analyses revealed that all six proposed predictors were significantly associated with QoL. Psychological factors made the greatest impact (ß = 0.213; p<0.003), followed by physical factors (ß = 0.19; p<0.001). CONCLUSION: PLHIV fairly agreed to have good QoL. The QoL was driven by mainly psychological and physical factors and not level of independence. However, the mean score perceptions for the investigated domains were low. Mental health services should consider these predictors when designing strategies to improve the QoL of PLHIV. While this study provides useful insights, other possible drivers of QoL among PLHIV should be investigated.

Predictors of antiretroviral therapy interruptions and factors influencing return to care at the Nkolndongo Health District, Cameroon.

BACKGROUND: Antiretroviral therapy is a lifelong commitment that requires consistent intake of tablets to optimize health outcomes, attain and maintain viral suppression. OBJECTIVE: We aimed to elicit predictors of treatment interruption amongst PLHIV and identify motivating factors influencing return to care. METHOD: We conducted a cross-sectional study using a mixed-method approach in four hospitals in Yaoundé. Sociodemographic and clinical data were collected from ART registers. Using purposeful sampling, thirteen participants were enrolled for interviews. Quantitative data were analyzed using Epi-Info and Atlas-TI for qualitative analysis. Ethical clearance approved by CBCHS-IRB. RESULTS: A total of 271 participants records were assessed. The mean age was 33 years (SD±11years). Private facilities CASS and CMNB registered respectively 53 (19.6%) and 14 (5.2%) participants while CMA Nkomo and IPC had 114 (42.1%) and 90 (33.2%) participants. Most participants (75.3%) were females [OR 1.14; CI 0.78-1.66] compare with males. 78% had no viral load test results. Transport cost and stigmatization constituted the most prominent predictors of treatment interruption (47.5%) and (10.5%) respectively. Belief in the discovery of an eminent HIV cure and the desire to raise offspring motivated 30% and 61%, respectively to resume treatment. CONCLUSION: Structural barriers like exposed health facility, and dispensing ARVs in open spaces stigmatizes clients and increases odds of attrition. Attrition of patients on ART will be minimized through implementation of client centered approaches like multiplying proxy ART pick points, devolving stable clients to community ARV model.

Risk factors for acute respiratory infections in children under five years attending the Bamenda Regional Hospital in Cameroon.

BACKGROUND: Acute respiratory infections (ARI) are a leading cause of morbidity and mortality in under-five children worldwide. About 6.6 million children less than 5 years of age die every year in the world; 95% of them in low-income countries and one third of the total deaths is due to ARI. This study aimed at determining the proportion of acute respiratory infections and the associated risk factors in children under 5 years visiting the Bamenda Regional Hospital in Cameroon. METHODS: A cross-sectional analytic study involving 512 children under 5 years was carried out from December 2014 to February 2015. Participants were enrolled by a consecutive convenient sampling method. A structured questionnaire was used to collect clinical, socio-demographic and environmental data. Diagnosis of ARI was based on the revised WHO guidelines for diagnosing and management of childhood pneumonia. The data was analyzed using the statistical software EpiInfo™ version 7. RESULTS: The proportion of ARIs was 54.7% (280/512), while that of pneumonia was 22.3% (112/512). Risk factors associated with ARI were: HIV infection ORadj 2.76[1.05-7.25], poor maternal education (None or primary only) ORadj 2.80 [1.85-4.35], exposure to wood smoke ORadj 1.85 [1.22-2.78], passive smoking ORadj 3.58 [1.45-8.84] and contact with someone who has cough ORadj 3.37 [2.21-5.14]. Age, gender, immunization status, breastfeeding, nutritional status, fathers' education, parents' age, school attendance and overcrowding were not significantly associated with ARI. CONCLUSION: The proportion of ARI is high and is associated with HIV infection, poor maternal education, exposure to wood smoke, passive cigarette smoking, and contact with persons having a cough. Control programs should focus on diagnosis, treatment and prevention of ARIs.

Hepatitis B, HIV, and Syphilis Seroprevalence in Pregnant Women and Blood Donors in Cameroon.

Objectives. We estimated seroprevalence and correlates of selected infections in pregnant women and blood donors in a resource-limited setting. Methods. We performed a cross-sectional analysis of laboratory seroprevalence data from pregnant women and voluntary blood donors from facilities in Cameroon in 2014. Rapid tests were performed to detect hepatitis B surface antigen, syphilis treponemal antibodies, and HIV-1/2 antibodies. Blood donations were also tested for hepatitis C and malaria. Results. The seroprevalence rates and ranges among 7069 pregnant women were hepatitis B 4.4% (1.1-9.6%), HIV 6% (3.0-10.2%), and syphilis 1.7% (1.3-3.8%) with significant variability among the sites. Correlates of infection in pregnancy in adjusted regression models included urban residence for hepatitis B (aOR 2.9, CI 1.6-5.4) and HIV (aOR 3.5, CI 1.9-6.7). Blood donor seroprevalence rates and ranges were hepatitis B 6.8% (5.0-8.8%), HIV 2.2% (1.4-2.8%), syphilis 4% (3.3-4.5%), malaria 1.9%, and hepatitis C 1.7% (0.5-2.5%). Conclusions. Hepatitis B, HIV, and syphilis infections are common among pregnant women and blood donors in Cameroon with higher rates in urban areas. Future interventions to reduce vertical transmission should include universal screening for these infections early in pregnancy and provision of effective prevention tools including the birth dose of univalent hepatitis B vaccine.
