Abstract
HIV remains a major cause of morbidity and mortality for people living in many low-income countries. With an HIV prevalence of 12.4% among people aged over 15 years, Mozambique was ranked in ...2019 as one of eight countries with the highest HIV rates in the world. We analyzed routinely collected data from electronical medical records in HIV-infected patients aged 15 years or older and enrolled at Carmelo Hospital of Chokwe in Chokwe from 2002 to 2019. Attrition was defined as individuals who were either reported dead or lost to follow-up (LTFU) (≥ 90 days since the last clinic visit with missed medical pick-up after 3 days of failed calls). Kaplan–Meier survival curves and Cox regression analyses were used to model the incidence and predictors of time to attrition. From January 2002 to December 2019, 16,321 patients were enrolled on antiretroviral therapy (ART): 59.2% were women, and 37.9% were aged 25–34 years old. At the time of the analysis, 7279 (44.6%) were active and on ART. Overall, the 16,321 adults on ART contributed a total of 72,987 person-years of observation. The overall attrition rate was 9.46 per 100 person-years. Cox regression showed a higher risk of attrition in those following an inpatient regimen (hazard ratio HR 3.18, 95% confidence interval CI 2.89–3.50;
p
< 0.001), having CD4 counts under 50 cells/µL (HR 1.91, 95% CI 1.63–2.24,
p
< 0.001), receiving anti-TB treatment within 90 days of ART initiation (HR 6.53, 95% CI 5.72–7.45;
p
< 0.001), classified as WHO clinical stage III (HR 3.75, 95% CI 3.21–4.37;
p
< 0.001), and having Kaposi’s sarcoma (HR 1.99, 95% CI 1.65–2.39,
p
< 0.001). Kaplan–Meier analysis showed that patients with CD4 counts of less than 50 cells/µL on ART initiation had a 40% lower chance of survival at 18 years. Low CD4 cell counts, ART initiation as an inpatient, WHO clinical stage III, and anti-tuberculosis treatment within 90 days of ART initiation were strongly associated with attrition. Strengthening HIV testing and ART treatment, improving the diagnosis of tuberculosis before ART initiation, and guaranteed psychosocial support systems are the best tools to reduce patient attrition after starting ART.
People living with HIV (PLHIV) and who are aware of their HIV status can access and benefit from antiretroviral therapy (ART) with subsequent individual and public health benefits; however, many ...PLHIV are unaware of their HIV status. We assessed the magnitude and determinants of self-reported non-receipt of HIV test results in adults aged 15-59 years old in Mozambique.
We performed a secondary analysis of data from the 2015 Mozambique Immunization indicators, Malaria and HIV/AIDS (IMASIDA 2015). Eligible adults (15-59 years) from each selected household were interviewed and data on sociodemographic characteristics, HIV knowledge, attitudes and behaviors, and HIV testing history were collected. Multivariable logistic regression assessed factors associated with self-reported non-receipt of HIV test results. Population representative estimates were calculated.
13,028 (90.8%) of 14,343 eligible participants were interviewed. A total of 6,654 (51.1%) respondents had previously been tested for HIV and were included in the analysis. Of these, 308 (4.6%; 95% CI: 3.70-5.77) self-reported not having received HIV test results. In the multivariable analysis, previous sexually transmitted infection (aOR: 2.76; 95% CI: 1.44-5.31), HIV stigmatizing attitudes (aOR: 1.96; 95% CI: 1.14-3.37), and lack of decision-making power towards health care seeking (aOR: 2.51; 95% CI: 1.39-4.52) were associated with non-receipt of HIV test results. Whereas, secondary or higher education (aOR: 0.25; 95% CI: 0.12-0.54), higher HIV knowledge (aOR: 0.47; 95% CI: 0.26-0.86), and age between 30-34 and 35-39 years old (aOR 0.47; 95% CI: 0.28-0.80; and aOR: 0.49; 95% CI: 0.27-0.90, respectively), were associated with receipt of HIV test results.
In this nationally representative survey, self-reported non-receipt of HIV test results was high and of public health relevance. These findings suggest adaptation of HIV counseling and testing programs emphasizing individualized approaches that target the youngest, least educated and the poorest individuals, especially those living in rural areas.
Globally, tuberculosis (TB) remains a serious cause of morbidity and mortality for children. Mozambique is 1 of 30 high TB and TB/HIV burden countries. This study aimed to assess treatment outcomes ...of childhood TB in Chókwè District, Mozambique.
A retrospective cohort study of children <15-years-old treated for TB from 2006 to 2017 was conducted at Carmelo Hospital of Chókwè. Descriptive statistics were used to summarize patient characteristics. Treatment outcomes stratified by HIV status were compared with χ. Multivariable logistic regression was used to estimate the odds of a favorable TB treatment outcome. Kaplan-Meier curves were used to estimate the cumulative incidence of death.
Nine hundred thirty-three cases of childhood TB were enrolled, 45.9% of which were female and 49.6% were <5-years-old. Five hundred sixty-five (62%) children were HIV positive. Seven hundred sixty-two (83.6%) cases had a favorable TB treatment outcome. In comparison to children 0-4 years, the 5-14 age group had a higher odds of a favorable outcome odds ratio: 2.02, 95% confidence interval: 1.42-3.05. Being 5-14 years was associated with lower risk of death (hazard ratio: 0.435; 95% confidence interval: 0.299-0.632). Those starting anti-TB treatment ≤3 months after antiretroviral therapy initiation had a survival probability of approximately 75% at 1 year compared with 95% for those who were HIV negative.
Most children in this cohort had favorable TB treatment outcomes. Worse outcomes were observed for younger children and if anti-TB treatment started ≤3 months after initiation of antiretroviral therapy. Rigorous screening for TB and isoniazid preventative therapy may reduce the burden of TB in this population and lead to better outcomes.
In 2017, rapid human immunodeficiency virus (HIV) testing services enabled the HIV diagnosis and treatment of approximately 15.3 million persons with HIV infection in sub-Saharan Africa with ...life-saving antiretroviral therapy (ART) (1). Although suboptimal testing practices and misdiagnoses have been reported in sub-Saharan Africa and elsewhere, trends in population burden and rate of false positive HIV diagnosis (false diagnosis) have not been reported (2,3). Understanding the population prevalence and trends of false diagnosis is fundamental for guiding rapid HIV testing policies and practices. To help address this need, CDC analyzed data from 57,655 residents aged 15-59 years in the Chókwè Health and Demographic Surveillance System (CHDSS) in Mozambique to evaluate trends in the rate (the percentage of false diagnoses among retested persons reporting a prior HIV diagnosis) and population prevalence of false diagnosis. From 2014 to 2017, the observed rate of false diagnosis in CHDSS decreased from 0.66% to 0.00% (p<0.001), and the estimated population prevalence of false diagnosis decreased from 0.08% to 0.01% (p = 0.0016). Although the prevalence and rate of false diagnosis are low and have decreased significantly in CHDSS, observed false diagnoses underscore the importance of routine HIV retesting before ART initiation and implementation of comprehensive rapid HIV test quality management systems (2,4,5).
