Background The potential effects of SARS-CoV-2 and Plasmodium falciparum co-infection on host susceptibility and pathogenesis remain unknown. We aimed to establish the prevalence of malaria and describe the clinical characteristics of SARS-CoV-2 and P falciparum co-infection in a high-burden malaria setting. Methods This was an exploratory prospective, cohort study of patients with COVID-19 who were admitted to hospital in Uganda. Patients of all ages with a PCR-confirmed diagnosis of SARS-CoV-2 infection who had provided informed consent or assent were consecutively enrolled from treatment centres in eight hospitals across the country and followed up until discharge or death. Clinical assessments and blood sampling were done at admission for all patients. Malaria diagnosis in all patients was done by rapid diagnostic tests, microscopy, and molecular methods. Previous P falciparum exposure was determined with serological responses to a panel of P falciparum antigens assessed using a multiplex bead assay. Additional evaluations included complete blood count, markers of inflammation, and serum biochemistries. The main outcome was overall prevalence of malaria infection and malaria prevalence by age (including age categories of 0–20 years, 21–40 years, 41–60 years, and >60 years). The frequency of symptoms was compared between patients with COVID-19 with P falciparum infection versus those without P falciparum infection. The frequency of comorbidities and COVID-19 clinical severity and outcomes was compared between patients with low previous exposure to P falciparum versus those with high previous exposure to P falciparum . The effect of previous exposure to P falciparum on COVID-19 clinical severity and outcomes was also assessed among patients with and those without comorbidities. Findings Of 600 people with PCR-confirmed SARS-CoV-2 infection enrolled from April 15, to Oct 30, 2020, 597 (>99%) had complete information and were included in our analyses. The majority (502 [84%] of 597) were male individuals with a median age of 36 years (IQR 28–47). Overall prevalence of P falciparum infection was 12% (95% CI 9·4–14·6; 70 of 597 participants), with highest prevalence in the age groups of 0–20 years (22%, 8·7–44·8; five of 23 patients) and older than 60 years (20%, 10·2–34·1; nine of 46 patients). Confusion (four [6%] of 70 patients vs eight [2%] of 527 patients; p=0·040) and vomiting (four [6%] of 70 patients vs five [1%] of 527 patients; p=0·014] were more frequent among patients with P falciparum infection than those without. Patients with low versus those with high previous P fal...

Improving quality of neonatal data capture and clinical care at a tertiary care hospital in Uganda through enhanced surveillance, training and mentorship.

Background: As COVID-19 disease surges across much of the world, researchers in different settings have a unique opportunity to address the various research priorities that have been identified. The challenges that containment and mitigation strategies present for research, especially in resource limited settings, could be significant and negatively impact the essential contribution of these settings to COVID-19 research. Objectives: To describe experiences of conducting research during this pandemic, discuss challenges faced and present strategies implemented to address these challenges Methods: Malaria Consortium recently initiated an observational case series study to assess the magnitude and clinical consequences of co-infection of COVID-19, malaria, and other common infections. This study is being conducted in eight COVID-19 treatment centres in Uganda. Qualitative methods including observations and interviews were utilized to document experiences and mitigating strategies for identified challenges. The main outcomes were a descriptive narrative of experiences conducting this research, discussion of challenges faced, and presentation of strategies implemented to address these challenges. Results: Expedited ethical review and approval facilitated timely initiation of research activities.  The primary clinical care teams at each treatment centre performed all study procedures to minimize infection. Given concerns about fomite transmission, considerations arose on how best to handle consent forms that had been signed or thumb-printed by patients to ensure that both hospital and research staff were not exposed to infection. Consenting severely ill or mentally impaired patients was also a challenge, especially when the next of kin was not available. Patient compensation was done through a mobile money/digital platform to avoid potential risks associated with cash. Patients, health care workers and study staff faced significant psychosocial challenges and anxiety that needed to be addressed. Conclusions: These experiences demonstrate that more adaptable and innovative approaches may be needed to support the implementation of research activities during this COVID-19 pandemic. This pandemic should also spur institutional review boards and investigators to respond to emerging challenges by updating policies and procedures around research review and approvals, and modifications in research methods.
