Determinants of survival of adolescents receiving antiretroviral therapy in the Centre Region of Cameroon: a multi-centered cohort-analysis.

BACKGROUND: In spite of the global decreasing mortality associated with HIV, adolescents living with HIV (ADLHIV) in sub-Saharan Africa still experience about 50% mortality rate. We sought to evaluate survival rates and determinants of mortality amongst ADLHIV receiving antiretroviral therapy (ART) in urban and rural settings. METHODS: A multi-centered, 10-year retrospective, cohort-study including ADLHIV on ART ≥ 6 months in the urban and rural settings of the Centre Region of Cameroon. Socio-demographic, clinical, biological, and therapeutic data were collected from files of ADLHIV. The Kaplan-Meier method was used to estimate survival probability after ART initiation; the log rank test used to compare survival curves between groups of variables; and the Cox proportional hazard model was used to identify the determinants of mortality. RESULTS: A total of 403 adolescents' records were retained; 340 (84%) were from the urban and 63 (16%) from the rural settings. The female to male ratio was 7:5; mean age (Standard deviation) was 14.1 (2.6) years; at baseline, 64.4% were at WHO clinical stages I/II, 34.9% had ≥ 500 CD4 cells/mm3, 91.1% were anemic, and the median [Inter Quartile Range] duration on ART was5.3 [0.5-16] years. The survival rate at 1, 5 and 10 years on ART was respectively 97.0%, 55.9% and 8.7%; with mean survival time of 5.8 years (95% CI 5.5-6.1). In bivariate analysis, living in the rural setting, non-disclosed HIV status, baseline CD4 count < 500 cells/mm3, not being exposed to nevirapine prophylaxis at birth and being horizontally infected were found to be the determinants of higher mortality with poor retention in care slightly associated with mortality. In multivariate analysis, living in rural settings, poor retention in care and anemia were independent predictors of mortality (p < 0.05). CONCLUSION: Although ADLHIV have good survival rate on ART after 1 year, we observe poor survival rates after 5 years and especially 10 years of treatment experience. Mitigating measures against poor survival should target those living in rural settings, anemic at baseline, or experiencing poor retention in care.

Prevalence, complications and factors associated with severely elevated blood pressure in patients with hypertension: a cross-sectional study in two hospitals in Yaoundé, Cameroon.

Introduction: severely elevated blood pressure significantly increases cardiovascular morbidity and mortality in hypertensive Black patients. The objective of this study was to determine the prevalence, complications and factors associated with severe high blood pressure in hypertensive patients in Yaoundé, Cameroon. Methods: we conducted a cross-sectional study in the outpatient and cardiology units of two teaching hospitals in Yaoundé. We included consenting hypertensive patients aged over 18 years. We first measured their blood pressure (BP), then we collected their sociodemographic data, cardiovascular risk factors, follow-up data, and ended with a complete physical examination. We performed a regression analysis to assess correlates of severe hypertension. Results: we included a total of 153 patients with 33 (21.6%) of them having severe hypertension. Among the 33 patients, 16 (48.5%) were male and 17 (51.5%) were female. Their mean age was 60.52 ± 12.83 years. Chronic kidney disease (78.8%), hypertensive retinopathy (69.7%) and left ventricular hypertrophy (48.5%) were the most common complications. On multiple logistic regression analysis, inadequate follow-up was independently associated with severe hypertension (adjusted OR=7.09; 95% CI [2.29-21.9]). Conclusion: severely elevated BP is common among hypertensive patients in our setting with important physical and economic consequences. Increased patients awareness and improving access to primary care physicians and cardiologists, through health insurance or other means, may be an effective strategy for reducing cardiovascular morbidity and mortality among hypertensive Black patients.

Pancreatic and splenic tuberculosis mimicking a pancreatic cancer with splenic metastases in an immunocompetent adolescent: a case report.

We present a case of pancreatic and splenic tuberculosis (TB) in a 15-year-old human immunodeficiency virus-negative patient who was initially misdiagnosed as suffering from a pancreatic carcinoma with splenic metastases. Pancreatic and splenic TB are extremely rare in young immunocompetent patients, with a nonspecific clinical presentation, making the diagnosis elusive.
