The novel coronavirus disease 2019 (COVID-19) was declared an international pandemic by the World Health Organization in March 2020. Throughout the pandemic, the association between diabetes mellitus (DM) and more severe COVID-19 has been well described internationally, with limited data, however, on South Africa (SA). The role of field hospitals in the management of patients with COVID-19 in SA has not yet been described. ⋯ In a resource-limited environment, interdisciplinary and interfacility collaboration ensured that complicated patients with DM and COVID-19 were successfully managed in a field hospital setting. Telemedicine offered a unique opportunity to identify high-risk patients in the community and link them to in-hospital monitoring and care. Future studies should explore ways to optimise this collaboration, as well as to explore possibilities for early identification and management of high-risk patients.

Observational Study
A national retrospective review of neonatal critical care transfers in dedicated critical care transport services in the private sector.
South Africa (SA) has a shortage of dedicated neonatal critical care services, which are mostly concentrated in urban areas, thus illustrating the need for neonatal critical care transport (CCT) services. Neonates who are transported by teams without the requisite experience and knowledge in neonatal care are at risk of severe adverse events during transport. This has led to the development of dedicated CCT teams by some emergency medical services. There is a paucity of national literature describing the neonatal population who undergo CCT in dedicated services. ⋯ This study provides insight into the demographics, most prevalent diagnoses, and interfacility transfer monitoring needs of neonates being transported in SA by two private dedicated CCT services. The results of this study should be used to inform future specialised neonatal CCT courses and qualifications, as well as the scopes of practice of providers transporting neonates.

Coeliac disease (CD) is an autoimmune condition occurring in genetically predisposed individuals exposed to an environmental trigger. The human leukocyte antigen (HLA) haplotypes HLA-DQ2.5 and HLA-DQ8 have the strongest association with CD, and 90 - 95% of CD patients bear these haplotypes. The susceptibility of the South African (SA) population to CD has not been studied previously. ⋯ The prevalence of HLA-DQ2.5 and HLA-DQ8 differed among SA study participants of different ethnicities. However, the notion that CD does not occur in black South Africans owing to lack of a genetic predisposition is incorrect.

Diabetes mellitus (DM) causes both micro- and macrovascular complications. The cochlea and auditory nerves are therefore at increased risk from DM-related complications due to microangiopathy, neuropathy or mitochondrial damage. Limited data are available from Africa detailing the association between DM and hearing impairment (HI). ⋯ We showed that HI occurs in over half of PLWD, usually within the first 10 years after diagnosis of DM. Symptoms of HI were shown to have positive associations with all HI categories except mild. A high level of vigilance for HI must be maintained in PLWD.

Severe infections in the absence of secondary immunodeficiency can alert clinicians to single-gene inborn errors of immunity/primary immunodeficiency disorders (PIDDs). Mendelian susceptibility to mycobacterial disease (MSMD) is characterised by selective susceptibility to mycobacterial infections due to inborn errors in the interleukin 12-interferon gamma pathway. The South African (SA) burden of hyperendemic tuberculosis (TB) infection provides an interesting context for the study of MSMD. ⋯ In the SA paediatric population, SPUR TB infections, particularly BCG/NTM, in the absence of secondary immunodeficiency, can alert to possible MSMD. The molecular diagnosis is pivotal, guiding disease classification and influencing clinical approach and management. The diagnosis is complex and requires a multidisciplinary approach with close collaboration between clinical immunologists, bioinformaticians, immunologists, clinical geneticists and genetic counsellors.
