RESUMO
Background: Heart failure (HF) is a growing public health concern with a high mortality rate in sub-Saharan Africa. However, few studies have reported the long-term predictors of mortality in this region. This study sought to determine the 3-year mortality rate and the predictors of mortality amongst HF patients in Douala, Cameroon. Methods: We conducted a prospective analysis on patients recruited in the Douala Heart Failure (Do-HF) registry, an ongoing prospective data collection on patients with HF at four cardiology units in Douala, Cameroon. Patients included were followed for 36 months from the index date of inclusion, with all-cause mortality as the primary outcome. Cox proportional hazard regression models were used to determine predictors of mortality. Results: Out of the 347 participants included, 318 (91.6%) completed follow-up. The mean age was 64±14 years, 172 (49.6%) were men. Hypertensive cardiomyopathy and dilated cardiomyopathy were the most frequent causes of heart failure. The median follow-up was 33 months, and 150 (47.2%) patients died. Independent predictors of mortality included New York Heart Association functional class III & IV (aHR 2.23; 95% CI: 1.49-3.33; P<0.001), presence of pulmonary rales (aHR 1.87; 95% CI: 1.30-2.68; P=0.005), chronic kidney disease (aHR 2.92; 95% CI: 1.79-4.78; P<0.001), enrolment as inpatient (aHR1.96; 95% CI: 1.17-2.54; P=0.005), no formal education (aHR 2.06; 95% CI: 1.28-3.33; P=0.003), and a monthly income of at most three minimum wage (aHR 2.06; 95% CI: 1.28-3.33; P=0.003). Conclusions: This study shows that almost half of HF patients die after 36 months of follow-up. Also, late presentation and poverty-related conditions were associated with poor outcomes. These findings suggest prioritizing preventive strategies that target early diagnosis and socioeconomic status to improve the prognosis of HF.
RESUMO
INTRODUCTION: HIV patients are now having longer life expectancies with the use of antiretroviral therapy (ART). However, the issue of mental illness has surfaced with depression being the most common in these patients, which has markedly reduced patient adherence to ART. In Cameroon, the management of HIV/AIDS does not incorporate psychiatric manifestations and depression is therefore underdiagnosed. The aim of our study was to determine the prevalence and determinants of depressive symptoms and their association with adherence to ART among HIV/AIDS patients on HAART in the Southwest Regional Hospitals of Cameroon. METHODS: This was a cross-sectional hospital-based study carried out in the BRH and LRH over a 3-month period. Three hundred HIV patients aged 21 and above were recruited. Depression and adherence to treatment were assessed using the nine-item Patient Health Questionnaire (PHQ-9) and eight-item Morisky Medication Adherence Scale questionnaires, respectively. Data were analysed using Epi-info version 3.4.5. RESULTS: The prevalence of depression was 26.7% (95% CI 20.6-33.7%); 75.0% of those with depression were non-adherent to HAART compared to 37.3% of those without depression (p value <0.001). The statistically significant risk factors associated with depression were unemployment (OR 2.38; 95% CI 1.26-4.50), age ≤40 years (OR 2.13; 95% CI 1.20-3.70) and CD4 counts ≤200 cells/µl (OR 3.70; 95% CI 1.45-9.09). CONCLUSION: The prevalence of depression was high and depression was significantly associated with non-adherence to HAART. Interventions to enhance early identification and treatment of depression in patients with HIV/AIDS are needed. Depression screening should be included as part of the routine consultation of HIV/AIDS patients to ensure early detection and treatment.
