Genetic factors associated with predisposition for COVID‐19 critical illness More than 20 host genetic variants that predispose patients who are infected with SARS‐CoV‐2 to become critically ill have been identified in a University of Queensland‐led study published in Nature. The findings may have direct implications for the development of new treatments and the future prioritisation of therapy. Critical illness in COVID‐19 is caused by inflammatory lung injury, which is mediated by the host’s immune system. Genetic factors are known to have a role, but researchers are only just beginning to understand the nature of the variants involved. In this study, researchers compared whole genome sequences of more than 7000 patients who became critically ill with COVID‐19 with those of more than 48 000 matched control individuals to identify 23 variants that predispose to life‐threatening disease. Sixteen of these are newly discovered variants. They include variants within genes involved in interferon signalling, leucocyte differentiation and the production of mucin proteins, which are important factors in the regulation of the immune system and functioning of the lung. Some of the variants identified are suitable targets for drugs, raising the possibility of new therapies designed to target the genetic mechanisms that predispose to life‐threatening disease. The results are also broadly consistent with a multicomponent model of COVID‐19, in which at least two distinct components can predispose to life‐threatening illness: a failure to control viral replication, and an enhanced tendency towards pulmonary inflammation and intravascular coagulation. https://www.nature.com/articles/s41586‐022‐04576‐6 Reading to at‐risk kids builds resilience Research from the University of South Australia, published in Child Abuse and Neglect, shows that reading aloud can triple a child’s resilience at school, particularly for children at‐risk. Focusing on early primary school‐aged children who had suffered abuse or neglect, the study explored factors that could modify the negative effects of adverse life circumstances, finding that one of the biggest predictors of resilience in both boys and girls in struggling families was being read to at home. While reading to children at home has long been associated with school readiness and scholastic outcomes, this is the first study that has shown the benefits of reading to mitigate some of the detrimental trajectories of child maltreatment. The study analysed data covering 65 083 children who had completed the Early Australian Development Census at 5–6 years of age, when starting primary school, identifying 3414 high risk children who had experienced maltreatment. Boys were found to be developmentally behind girls, particularly those who had been exposed to abuse or neglect. Among high risk children, 51.2% demonstrated resilience. Predictors of resilience in the multivariable model were being older, not having an emotional condition, and being read to at home. Risk factors were being male, living in rural or remote areas, having a physical or sensory disability, or having a learning disability. https://www.sciencedirect.com/science/article/abs/pii/S0145213421003707

Barriers to accessing HIV pre‐exposure prophylaxis for Medicare‐ineligible people in Melbourne, Australia: analysis of patients attending the PrEPMe Clinic
To the Editor: People without Medicare coverage cannot access Pharmaceutical Benefits Scheme (PBS)‐subsidised human immunodeficiency virus (HIV) pre‐exposure prophylaxis (PrEP) or associated clinical care. Rates of HIV infection diagnosis are disproportionately higher among overseas‐born gay and bisexual men compared with Australian‐born gay and bisexual men.1 In response, in June 2020, the Alfred Hospital and the Victorian Infectious Diseases Reference Laboratory established the free PrEPMe Clinic for Medicare‐ineligible people. Data were collected using proformas after patients provided verbal consent (Alfred Health Ethics Committee approval No. 656/18). The first 100 consecutive patients were all born overseas (Box). Melbourne’s only public sexual health clinic referred 65 patients. Almost all patients were male, all patients had sex with men and reported a median of three sexual partners in 3 months at baseline; 76 patients inconsistently used condoms for anal sex. Fifty‐eight patients reported previous sexually transmissible infections (STIs); STIs were diagnosed in 12/100 patients at baseline, a rate similar to that found in Medicare‐eligible PrEP users.2 Thirty‐four patients had previously accessed HIV post‐exposure prophylaxis (PEP), and 49 patients had previously unsuccessfully attempted to obtain PrEP. The reported barriers to access mainly included costs of medical appointments and pathology, and difficulties navigating Australia’s health care system. All patients received a non‐PBS PrEP prescription. At 3‐month follow‐up, 87 patients had commenced PrEP. Local pharmacies supplied PrEP at cost price (A$40–55 per month) or free to patients with financial hardship; other patients purchased PrEP online (US$20–30 per month) or obtained free PrEP online using assistance coupons (www.pan.org.au; Box). Most patients who ordered PrEP online experienced delivery delays of 4–6 weeks, leaving them at risk of HIV infection. We report that Medicare‐ineligible gay and bisexual men and transgender women were at high risk of HIV infection, yet faced significant financial barriers to accessing PrEP. PrEP uptake has been associated with significant population‐level declines in incident HIV infection in Australia.3 Australia’s Eighth National HIV Strategy aims for virtual elimination of HIV transmissions by 2022,4 and to achieve this goal, Australia must provide universally subsidised PrEP medication and clinical services, irrespective of Medicare status.5 Medicare‐ineligible gay and bisexual men often already attend publicly funded sexual health clinics for free HIV/STI testing and treatment, as reported here. In a high income country like Australia, the additional cost of providing universally subsidised PrEP care would likely be lower than treating preventable new HIV infections, with an estimated lifetime cost of more than US$350 000 per HIV infection diagnosis.6 Box – Demographic characteristics, immunodeficiency virus (HIV) acquisition risk, and prior efforts to obtain pre‐exposure prophylaxis (PrEP) in the first 100 consecutive patients to attend the PrEPMe HIV prevention clinic at the Alfred Hospital in Melbourne, Australia* Values Total number of patients 100 Demographic characteristics Region of birth Asia 47 Latin America 31 Europe 14 Other 8 Age, years, median (IQR) 28 (26–31) Gender Cisgender male 96 Transgender female 4 Visa status Student visa 62 Working visa 34 Other 4 Referral sources Melbourne Sexual Health Centre 65 Word of mouth 16 Other† 13 Unknown 6 HIV risk at initial clinical assessment Sexual partners (3 months), median (IQR) 3 (1–5) Condom use for anal sex (3 months) Always 24 Mostly or sometimes 60 Never 13 Not applicable 1 Unknown 2 Previous STIs (ever) Yes 58 No 42 Previous STIs (ever, specific STIs) Gonorrhoea 35 Chlamydia 21 Syphilis 21 Other‡ 5 STIs diagnosed at baseline Chlamydia only 6 Other§ 6 Previous attempts at HIV risk reduction Previous use of PEP Yes 34 No 57 Unknown 9 Previous unsuccessful attempts to obtain PrEP Yes 49 No 46 Unknown 5 PrEP commencement by 3‐month follow‐up Commenced PrEP 87 Local pharmacy 65 Online 19 Online order did not arrive, then purchased at pharmacy 3 PrEP not commenced 6 Online order did not arrive 3 Other¶ 3 Lost to follow‐up 7 COVID‐19 = coronavirus disease 2019; IQR = interquartile range; PEP = post‐exposure prophylaxis; STIs = sexually transmissible infections. * Enrolment dates: 1 June 2020 to 26 October 2020. † Includes general practices, internet search, “PrEP Access Now” Facebook page, Alfred Hospital PEP program. ‡ Includes herpes simplex virus, Mycoplasma genitalium, hepatitis B virus. § Includes syphilis, hepatitis B virus, both chlamydia and gonorrhoea. ¶ Includes lost prescription, no sex due to COVID‐19.

The Virtual Inpatient Diabetes Management Service: COVID‐19 brings the future to inpatient diabetes management
To the Editor: The coronavirus disease 2019 (COVID‐19) pandemic has strained health systems in New South Wales, and hospitals have rapidly adapted to care for inpatients with COVID‐19. In the 4 weeks leading up to 9 September 2021, 9330 locally acquired cases were diagnosed in Western Sydney alone.1 The management of large numbers of COVID‐19 inpatients with diabetes has been challenging. People with diabetes are a vulnerable population who are at risk of adverse outcomes from COVID‐19, with a two‐ to threefold likelihood of death compared with people without diabetes.2 Hyperglycaemia is associated with higher risk;3 hence, good glucose management is desirable. Exacerbation of diabetes by dexamethasone therapy, used to treat patients with COVID‐19, and the development of steroid‐induced hyperglycaemia in non‐diabetic patients present further challenges. Traditional models of care relying on referrals from parent teams to an endocrinologist (or registrar), who then reviews the patient daily to chart insulin, are inefficient and impractical for this situation. We have developed a virtual inpatient diabetes management service (vIDMS) as a means for a small diabetes team to manage COVID‐19 inpatients with diabetes. The success of this model has revolved around an electronic medical record, electronic inpatient prescribing, a diabetes dashboard, and videoconferencing communications. The recording of all glucose measurements (including point of care) within the electronic medical record has enabled the systematic capture and display of hospital‐wide glucose data on a diabetes dashboard (Box). This also allows viewing and filtering by any variable in the electronic medical record, such as ward, age, biochemistry (including formal laboratory glucose and glycated haemoglobin), development of hypoglycaemia, prescribed medications (including corticosteroids), and COVID‐19 status. Therefore, COVID‐19 patients with diabetes or hyperglycaemia are easily identified. The vIDMS, comprising of a consultant, a registrar and a diabetes educator, reviewed patients with COVID‐19 and hyperglycaemia on a daily basis, using the dashboard and electronic medical record, by sharing a screen on a videoconferencing platform. Remote management was undertaken through the electronic medical record, including medication and insulin dose adjustments. Communication with ward staff and patients with COVID‐19 through the electronic medical record, or by telephone or video, was undertaken when needed, including for diabetes education. Entry into the COVID‐19 wards and usage of personal protective equipment was not required. In the 6 weeks to 5 September 2021, 112 COVID‐19 patients with diabetes were thus managed in Westmead Hospital (median age, 62 years; range, 23–91 years), with up to 40 patients reviewed per day. Necessitated by COVID‐19, the future of inpatient diabetes management is now here. With one‐quarter of patients in metropolitan hospitals having self‐reported diabetes4 but insufficient specialised diabetes staff to provide individual management, the vIDMS will become a significant part of the wider model of diabetes care for large hospitals.5 While initial and intermittent face‐to‐face contact remains valuable to build a relationship and discuss relevant issues, and careful review of medical records is necessary to understand perturbations in glucose levels (eg, fasting, missed medication), the vIDMS enables daily specialist care for large numbers of patients with diabetes by a small team. The health system needs to facilitate its wider application for the management of both COVID‐19 and non‐COVID‐19 patients with diabetes in hospital.
