Evidence of greater severity of diabetic foot ulcers during COVID‐19 pandemic: A real‐life single‐centre cohort study

Abstract

AbstractAimsIn the Sars‐Cov‐2 pandemic era, patients with diabetes mellitus (DM) manifested more severe forms of Sars‐Cov‐2 with greater mortality than non‐diabetic patients. Several studies documented more aggressive forms of diabetic foot ulcers (DFU) during the pandemic period even though the results were not unanimously confirmed. The aim of this study was to evaluate the clinical‐demographic differences between a cohort of Sicilian diabetic patients hospitalised for DFU in the pre‐pandemic 3 years and a cohort of patients hospitalised in the pandemic 2 years.Materials and MethodsOne hundred and eleven patients from the pre‐pandemic period 2017–2019 (Group A) and 86 patients from the pandemic period 2020–2021 (Group B) with DFU, admitted to the division of Endocrinology and Metabolism of the University Hospital of Palermo, were retrospectively evaluated. The clinical assessment of the type, staging and grading of the lesion, and the infective complication from DFU was performed.ResultsNo differences in HbA1c values were observed between the two groups. Group B showed a significantly higher prevalence of male subjects (p = 0.010), neuro‐ischaemic ulcers (p < 0.001), deep ulcers with involvement of bones (p < 0.001), white blood count levels (p < 0.001), and reactive C protein (p = 0.001) compared to group A.ConclusionsOur data show that in the COVID‐19 pandemic, a greater severity of ulcers requiring a significantly greater number of revascularisations and more expensive therapy, but without an increase in the amputation rate, was observed. These data provide novel information on the impact of the pandemic on diabetic foot ulcer risk and progression.
