Objectives. This study screened for factors aﬀecting coronavirus disease 2019 (COVID-19) incidence in type 1 diabetes mellitus
(T1DM) patients, appraised vitamin D’s eﬃcacy in preventing COVID-19, and assessed the eﬀects of clinical characteristics,
glycemic status, vitamin D, and hydroxychloroquine administration on COVID-19’s progression and severity in T1DM
patients. Methods. This retrospective research on 150 adults was conducted at Security Forces Hospital, Riyadh, KSA.
Participants were allocated to three groups (50/group): control, T1DM, and T1DM with COVID-19. Participants’ fasting blood
glucose (FBG), glycated hemoglobin (HbA1c), complete blood count, vitamin D, C-reactive protein (CRP), erythrocyte
sedimentation rate (ESR), ferritin, lactate dehydrogenase (LDH), prothrombin time, activated partial thromboplastin time,
D-dimer, liver and kidney function, and hydroxychloroquine treatment were retrieved and analyzed. Results. The percentages of
comorbidities and not taking hydroxychloroquine were signiﬁcantly higher among T1DM patients with COVID-19 than
patients with T1DM only. Mean vitamin D level was signiﬁcantly lower in T1DM with COVID-19 patients than in the other
two groups. Vitamin D showed a signiﬁcant negative correlation with LDH, CRP, ESR, ferritin, and D-dimer, which was the
most reliable predictor of COVID-19 severity in T1DM patients. Conclusion. Comorbidities and vitamin D deﬁciency are risk
factors for COVID-19 in patients with T1DM. Patients who do not take hydroxychloroquine and have higher FBG and HbA1c
levels are vulnerable to COVID-19. Vitamin D may be useful for preventing COVID-19 in T1DM patients. Comorbidities,
higher FBG and HbA1c levels, not taking hydroxychloroquine, and vitamin D inadequacy elevate COVID-19 progression and
severity in patients with T1DM.
