Objective: This study aimed to estimate the incidence of new diabetes mellitus (DM) and cardiovascular diseases (CVD) up to one year after Covid-19 compared with matched controls. Methods: A cohort study was conducted using electronic records for 1,473 family practices with a population of 14.9 million. Covid-19 patients without DM or CVD were individually matched with controls and followed up to October 2021. A difference-in-difference analysis estimated the net effect of Covid-19 allowing for baseline differences and covariates. Results: There were 372,816 Covid-19 patients, with 2,935 CVD and 3,139 DM events, and 372,816 matched controls with 1,193 CVD and 1,861 DM events following the index date. Net incidence of DM increased in acute Covid-19 up to four weeks from index date (adjusted rate ratio, RR 1.71, 1.40 to 2.10) and remained elevated in post-acute (five to 12 weeks from index date; RR 1.17, 1.01 to 1.36) and long-Covid-19 (13 to 52 weeks, 1.20, 1.09 to 1.31). Acute Covid-19 was associated with net increased CVD incidence (RR 6.02, 95% confidence interval 4.84 to 7.47) including pulmonary embolism (RR 14.5, 7.72 to 27.4), atrial arrythmias (6.58, 3.78 to 11.4) and venous thromboses (5.44, 3.22 to 9.17). CVD incidence declined in post-acute Covid-19 (R 1.68, 1.41 to 2.01) and showed no net increase in long Covid-19 (0.95, 0.85 to 1.06). Conclusions: DM incidence remains elevated up to one year following Covid-19. CVD is increased early after Covid-19 mainly from pulmonary embolism, atrial arrhythmias and venous thromboses.

The Impact

IntroductionPeople living with HIV (PLHIV) are increasingly at risk of age-related comorbidities such as diabetes mellitus (DM). While DM is associated with elevated mortality and morbidity, understanding of DM among PLHIV is limited. We assessed the incidence of DM among people living with and without HIV in British Columbia (BC), Canada, during 2001–2013.MethodsWe used longitudinal data from a population-based cohort study linking clinical data and administrative health data. We included PLHIV who were antiretroviral therapy (ART) naïve at baseline, and 1:5 age-sex-matched persons without HIV. All participants had ≥5 years of historic data pre-baseline and ≥1 year(s) of follow-up. DM was identified using the BC Ministry of Health’s definitions applied to hospitalisation, physician billing and drug dispensation datasets. Incident DM was identified using a 5-year run-in period. In addition to unadjusted incidence rates (IRs), we estimated adjusted incidence rate ratios (IRR) using Poisson regression and assessed annual trends in DM IRs per 1000 person years (PYs) between 2001 and 2013.ResultsA total of 129 PLHIV and 636 individuals without HIV developed DM over 17 529 PYs and 88,672 PYs, respectively. The unadjusted IRs of DM per 1000 PYs were 7.4 (95% CI 6.2 to 8.8) among PLHIV and 7.2 (95% CI 6.6 to 7.8) for individuals without HIV. After adjustment for confounding, HIV serostatus was not associated with DM incidence (adjusted IRR: 1.03, 95% CI 0.83 to 1.27). DM incidence did not increase over time among PLHIV (Kendall trend test: p=0.9369), but it increased among persons without HIV between 2001 and 2013 (p=0.0136).ConclusionsAfter adjustment, HIV serostatus was not associated with incidence of DM, between 2001 and 2013. Future studies should investigate the impact of ART on mitigating the potential risk of DM among PLHIV.
