The prevalence of renal impairment among adults with early HIV disease in Blantyre, Malawi

We determined the prevalence of renal impairment and possible HIV-associated nephropathy (HIVAN) in adults with World Health Organization (WHO) stages I or II HIV, presenting to the antiretroviral therapy (ART) clinic in a central hospital in Malawi. We enrolled 526 ART-naïve subjects, 67% women, median age 34 (17-73) years and mean CD4 count 305 (3-993) cells/μL. Blood pressure, weight, urine dipstick and microscopy, CD4 cell count and serum creatinine were measured. Creatinine clearance (CrCL) was estimated using the Cockcroft-Gault equation. Possible HIVAN was diagnosed based on levels of proteinuria and CrCl. In all, 23.3% had proteinuria (≥ 1+). 57.4% had reduced CrCl (< 90 mL/minute): 18.8% had moderate (CrCl 30-59 mL/minute) and 2.2% severe (CrCl <30 mL/minute) renal dysfunction. Extrapolating from renal biopsy studies that confirmed HIVAN, the proportion of patients with HIVAN in our clinic ranges from 1.8-21.2%. We conclude that renal impairment was common, though rarely severe, among HIV-infected adults with clinically non-advanced HIV disease. Renal dysfunction has been demonstrated to be a risk factor for (early) mortality. These results are relevant for ART programmes, such as those in Malawi, where renal function is not routinely assessed.

Healthcare workers' experiences in caring for critically ill COVID-19 patients at a tertiary hospital in Malawi

Introduction

The coronavirus pandemic overwhelmed the healthcare landscape, placing a strain on healthcare workers worldwide. In addition to directly causing the deaths of people, the COVID-19 pandemic disrupted critical health services in developing countries. The study aimed to explore the experiences of healthcare workers who cared for critically ill COVID-19 patients at a tertiary hospital in Malawi.

Methods

A qualitative descriptive design was used. Data were gathered through in-depth interviews with doctors, clinical officers, nurses, and allied staff (n=25) who were involved in the care of critically ill COVID-19 patients at the hospital's COVID-19 treatment centres during the first and second waves of the pandemic in Malawi. The interviews were conducted in English, audiotaped, and later transcribed verbatim. Conventional content analysis was used to analyse the data following the steps proposed by Hsieh and Shannon1.

Results

The overall experience of the health workers was negative. However, delivering care to critically ill COVID-19 patients was associated with positive and negative experiences. The positive experience was a result of teamwork among staff and support from hospital authorities and the community. Negative experiences, on the other hand, were attributed to a lack of knowledge and skills in managing critically ill COVID-19 patients, a lack of resources, and abuse by some patients and members of the community. Furthermore, there was fear of contracting the virus from patients and fellow health workers while providing care.

Conclusion

The findings point to the need for adequate preparedness within the health sector to support and protect the healthcare workers and individuals they look after. There is a need for disease awareness strategies for health workers and the general public for future pandemics.

Cryptosporidium parvum and Isospora belli infections among patients with and without diarrhoea

OBJECTIVE

To assess the importance of Cryptosporidium parvum and Isospora belli infections as a cause of diarrhoea among patients admitted to the Medical Wards in Queen Elizabeth Central Hospital (QECH) in Blantyre, Malawi.

DESIGN

Prospective case control study.

SUBJECTS

One hundred and twenty one patients with diarrhoea and 122 patients without diarrhoea.

MAIN OUTCOME MEASURES

Demonstration of C. parvum and I. belli oocysts by examination of at least one stool sample per patient using phenol auramine-O-fluorescence staining and an immuno-fluorescent assay with monoclonal antibodies against Cryptosporidium, seropositivity for HIV and AIDS.

RESULTS

In 22% of the patients with diarrhoea an infection with C. parvum or I. belli was found. Thirteen (11%) of them had a C. parvum and 14 (12%) an I. belli infection; a mixed infection was found in one patient. In the control group, three (3%) C. parvum and three (3%) I. belli infections were seen. The prevalence of both infections was very significantly higher in the cohort of diarrhoea patients than in the controls, 13/108 versus 3/119 (p=0.0099) for C. parvum, and 14/107 versus 3/119 (p=0.0056) for I. belli. Infections were only seen in HIV positive patients. Two hundred and four (84%) patients were HIV positive and 145 (60%) of them had AIDS.

CONCLUSIONS

C. parvum and I. belli infections are a significant cause of diarrhoea among medical in-patients at QECH. Examinations of stool specimen for parasites among hospitalised patients with diarrhoea provide data for a more appropriate management.

Doctors' experiences of referring and admitting patients to the intensive care unit: a qualitative study of doctors' practices at two tertiary hospitals in Malawi

OBJECTIVE

To explore doctors' experiences of referring and admitting patients to the intensive care unit (ICU) at two tertiary hospitals in Malawi.

DESIGN

This was a qualitative study that used face-to-face interviews. The interviews were audiotaped and transcribed verbatim into English. The data were analysed manually through conventional content analysis.

SETTING

Two public tertiary hospitals in the central and southern regions of Malawi. Interviews were conducted from January to June 2021.

PARTICIPANTS

Sixteen doctors who were involved in the referral and admission of patients to the ICU.

RESULTS

Four themes were identified namely, lack of clear admission criteria, ICU admission requires a complex chain of consultations, shortage of ICU resources, and lack of an ethical and legal framework for discontinuing treatment of critically ill patients who were too sick to benefit from ICU.

CONCLUSION

Despite the acute disease burden and increased demand for ICU care, the two hospitals lack clear processes for referring and admitting patients to the ICU. Given the limited bed space in ICUs, hospitals in low-income countries, including Malawi, need to improve or develop admission criteria, severity scoring systems, ongoing professional development activities, and legislation for discontinuing intensive care treatments and end-of-life care.
