Abstract Background Compared to the abundance of clinical and genomic information available on patients hospitalised with COVID-19 disease from high-income countries, there is a paucity data low-income countries. Our aim was explore relationship between viral lineage patient outcome. Methods We enrolled prospective observational cohort adult PCR-confirmed July 2020 March 2022 Blantyre, Malawi, covering four waves SARS-CoV-2 infections. Clinical diagnostic were collected using an adapted...
Introduction Despite growing evidence of the long-term impact tuberculosis (TB) on quality life, Global Burden Disease (GBD) estimates TB-related disability-adjusted life years (DALYs) do not include post-TB morbidity, and evaluations TB interventions typically assume treated patients return to pre-TB health. Using primary data, we estimate lost due disability (YLDs), premature mortality (YLL) DALYs associated with cardiorespiratory morbidity in a low-income country. Methods Adults aged ≥15...
Rationale Pulmonary tuberculosis (PTB) can cause post-TB lung disease (PTLD) associated with respiratory symptoms, spirometric and radiological abnormalities. Understanding of the predictors natural history PTLD is limited. Objectives To describe symptoms function Malawian adults up to 3 years following PTB-treatment completion, determine evolution over this period. Methods Adults successfully completing PTB treatment in Blantyre, Malawi were followed for assessed using questionnaires,...
Although the COVID-19 pandemic has left no country untouched there been limited research to understand clinical and immunological responses in African populations. Here we characterise patients hospitalised with suspected (PCR-negative/IgG-positive) or confirmed (PCR-positive) COVID-19, healthy community controls (PCR-negative/IgG-negative). PCR-positive participants were more likely receive dexamethasone a beta-lactam antibiotic, survive hospital discharge than PCR-negative/IgG-positive...
BackgroundThe effect of childhood pneumococcal conjugate vaccine implementation in Malawi is threatened by absence herd effect. There persistent vaccine-type carriage both vaccinated children and the wider community. We aimed to use a human infection study measure 13-valent (PCV13) efficacy against carriage.MethodsWe did double-blind, parallel-arm, randomised controlled trial investigating PCV13 or placebo experimental Streptococcus pneumoniae serotype 6B (strain BHN418) among healthy adults...
The aim of this study was to describe the current status diabetes care in an urban clinic Malawi and prevalence human immunodeficiency virus (HIV) population, investigating possible associations between HIV diabetes. A systematic prospective survey patients attending at a teaching hospital Blantyre, conducted. Six hundred twenty were assessed. Seventy-four percent had glycosylated hemoglobin (HbA1C) > 7.5%. Systolic blood pressure 140 mm Hg 52% patients. Hypertension more common with raised...
Pulmonary TB survivors face a high burden of post-TB lung disease (PTLD) after treatment completion. In this secondary data analysis we investigate the performance parameters measured at completion in predicting morbidity over subsequent year, to inform programmatic approaches PTLD screening low-resource settings. Cohort from urban Blantyre, Malawi were used construct regression models for five outcomes (chronic respiratory symptoms or functional limitation, ongoing health seeking,...
Introduction: Chronic obstructive pulmonary disease (COPD) continues to pose a global public health challenge. However, literature is scarce on the burden of COPD in Malawi. We assessed prevalence and risk factors for among adults Neno, Methodology: conducted population-based analytical cross-sectional study Neno District between December 2021 November 2022. Using multi-stage sampling technique, we included 525 aged≥ 40 years. All participants underwent spirometry according American Thoracic...
Up to 14% of Malawian adults die during the intensive phase tuberculosis treatment. In a prospective cohort 199 with microbiologically confirmed pulmonary tuberculosis, clinical and laboratory parameters were compared between those who died or deteriorated had an uneventful recovery. Baseline tumor necrosis factor alpha responses stimulation heat-killed Mycobacterium lipopolysaccharide reduced among 22 patients poor outcome (P = .017). Low body mass index .002) elevated respiratory rate .01)...

Background The epidemic of non-communicable diseases (NCDs) in low and middle income countries (LMICs) is widely recognised as the next major challenge to global health. However, many LMICs, infectious are still prevalent resulting a “double burden” disease. With increased life expectancy longevity with HIV, older adults may particularly be at risk this double burden. Here we describe relative contributions infections NCDs hospital admissions mortality, according age, Malawi’s largest...

Cardiovascular disease (CVD) is a major cause of death in Malawi. In rural districts, heart failure (HF) care limited and provided by non-physicians.

The coronavirus disease 2019 (COVID-19) pandemic is now established on the African continent, with cases rapidly increasing in Malawi (1742 confirmed and 19 deaths as of 5 July 20201). Clinicians require guidelines, deliverable context, to effectively safely treat patients for best possible outcome. In Malawi, key public messages around social distancing, hand washing shielding at-risk individuals have been widely distributed by Ministry Health. However, it has not implement strict lockdown...

The Malawian health sector has a strong tradition of systematic data collection for monitoring and evaluation large-scale services. A highly successful adapted Directly Observed Treatment, Short course “DOTS” framework, based on patient registers paperbased mastercards was introduced to facilitate the management scale up antiretroviral therapy. Subsequently, simple, touch-screen electronic medical record system (EMRs) effectively at high burden ART sites. Based this model, in 2010, diabetes...
