Barriers and facilitators to integration of screening for hypertension, diabetes mellitus and dyslipidaemia, among adult people living with HIV at district hospital ART clinics in Southern Malawi.

Background: Atherosclerotic cardiovascular diseases (ASCDs) are a significant health concern globally and in Sub-Saharan Africa (SSA), particularly for people living with HIV (PLWH). Hypertension, diabetes mellitus (DM), and dyslipidaemia significantly increase the risk of ASCDs, and integrating screening for these conditions in public health facilities remains challenging in Malawi. This study aimed to explore the barriers and facilitators to integrating screening for hypertension, DM and dyslipidaemia among adult PLWH at district hospital ART clinics in Southern Malawi.

Global health collaborative research: beyond mandatory collaboration to mandatory authorship.

Collaborative research between the global north and global south is common and growing in number. Due to inability of local governments to fund research, global north actors provide the bulk of research funding. While providing mutual benefits, global collaborative research projects are far from ideal.

Cross-sectional health centre and community-based evaluation of the impact of pneumococcal and malaria vaccination on antibiotic prescription and usage, febrile illness and antimicrobial resistance in young children in Malawi: the IVAR study protocol.

Introduction: Vaccination is a potentially critical component of efforts to arrest development and dissemination of antimicrobial resistance (AMR), though little is known about vaccination impact within low-income and middle-income countries. This study will evaluate the impact of vaccination on reducing carriage prevalence of resistant and extended spectrum beta-lactamase-producing and species. We will leverage two large ongoing cluster-randomised vaccine evaluations in Malawi assessing; first, adding a booster dose to the 13-valent pneumococcal conjugate vaccine (PCV13) schedule, and second, introduction of the RTS,S/AS01 malaria vaccine.

Artemether-lumefantrine efficacy among adults on antiretroviral therapy in Malawi.

Background: When people with human immunodeficiency virus (HIV) infection (PWH) develop malaria, they are at risk of poor anti-malarial treatment efficacy resulting from impairment in the immune response and/or drug-drug interactions that alter anti-malarial metabolism. The therapeutic efficacy of artemether-lumefantrine was evaluated in a cohort of PWH on antiretroviral therapy (ART) and included measurement of day 7 lumefantrine levels in a subset to evaluate for associations between lumefantrine exposure and treatment response.

Methods: Adults living with HIV (≥ 18 years), on ART for ≥ 6 months with undetectable HIV RNA viral load and CD4 count ≥ 250/mm were randomized to daily trimethoprim-sulfamethoxazole (TS), weekly chloroquine (CQ) or no prophylaxis.

The prevalence of Schistosoma mansoni infection among adults with chronic non-communicable diseases in Malawi.

Background: Schistosomiasis is a parasitic infectious disease caused by flatworms of the Schistosoma genus. The global burden of schistosomiasis is high. In Malawi, schistosomiasis is among the top 20 causes of outpatient department visits in health facilities.

Performance and safety of the induced sputum procedure in young children in Malawi: a prospective study.

Background: Collecting sputum specimens is a challenge in infants and young children. We assessed the performance and safety of induced sputum (IS) collection in this population, embedded in a prospective study evaluating respiratory cryptosporidiosis in Malawian children with diarrheal disease.

Methods: We assessed the sputum quality and correlation with detection of Cryptosporidium spp.

Respiratory cryptosporidiosis in Malawian children with diarrheal disease.

Background: Respiratory cryptosporidiosis has been documented in children with diarrhea. We sought to describe the dynamics of respiratory involvement in children hospitalized with gastrointestinal (GI) diarrheal disease.

Methods: We conducted a prospective, observational longitudinal study of Malawian children 2-24 months hospitalized with diarrhea.

Revisiting Co-trimoxazole Prophylaxis for African Adults in the Era of Antiretroviral Therapy: A Randomized Controlled Clinical Trial.

Background: Daily co-trimoxazole is recommended for African adults living with human immunodeficiency virus (HIV) irrespective of antiretroviral treatment, immune status, or disease stage. Benefits of continued prophylaxis and whether co-trimoxazole can be stopped following immune reconstitution are unknown.

Methods: We conducted a randomized controlled trial at 2 sites in Malawi that enrolled adults with HIV with undetectable viral load and CD4 count of >250/mm3 and randomized them to continue daily co-trimoxazole, discontinue daily co-trimoxazole and begin weekly chloroquine, or discontinue daily co-trimoxazole.

Compensation of subjects for participation in biomedical research in resource - limited settings: a discussion of practices in Malawi.

Background: Compensating participants of biomedical research is a common practice. However, its proximity with ethical concerns of coercion, undue influence, and exploitation, demand that participant compensation be regulated. The objective of this paper is to discuss the current regulations for compensation of research participants in Malawi and how they can be improved in relation to ethical concerns of coercion, undue influence, and exploitation.

Evaluating respiratory cryptosporidiosis in pediatric diarrheal disease: protocol for a prospective, observational study in Malawi.

Background: Cryptosporidium is among the most common causes of severe diarrhea in African children 0-23 months old. It is associated with excess mortality, stunting and malnutrition. The most common manifestation of cryptosporidium is intestinal diarrheal disease.

Frequent malaria illness episodes in two Malawian patients on antiretroviral therapy soon after stopping cotrimoxazole preventive therapy.

We describe two Malawian adults on successful antiretroviral therapy who experienced frequent malaria episodes after stopping cotrimoxazole prophylaxis. We argue that, in addition to stopping cotrimoxazole, diminished malaria immunity and drug interactions between efavirenz and artemether-lumefantrine may have played a causative role in the recurrent malaria our patients experienced.

TSCQ study: a randomized, controlled, open-label trial of daily trimethoprim-sulfamethoxazole or weekly chloroquine among adults on antiretroviral therapy in Malawi: study protocol for a randomized controlled trial.

Background: Before antiretroviral therapy (ART) became widely available in sub-Saharan Africa, several studies demonstrated that daily trimethoprim-sulfamethoxazole (TS) prophylaxis reduced morbidity and mortality among HIV-infected adults. As a result, the World Health Organization (WHO) recommended administering TS prophylaxis to this group. However, the applicability of the results to individuals taking ART and living in sub-Saharan Africa has not been definitively evaluated.

Is it ethical to prevent secondary use of stored biological samples and data derived from consenting research participants? The case of Malawi.

Background: This paper discusses the contentious issue of reuse of stored biological samples and data obtained from research participants in past clinical research to answer future ethical and scientifically valid research questions. Many countries have regulations and guidelines that guide the use and exportation of stored biological samples and data. However, there are variations in regulations and guidelines governing the reuse of stored biological samples and data in Sub-Saharan Africa including Malawi.
