Decubitus Ulcers of Soft Tissues in Patients with Type 2 Diabetes Mellitus: Clinical Strategies, Insulin Resistance Indicators, Comprehensive Treatment Aspects
Abstract
Background. The causes of decubitus ulcers include ischaemia and neurotrophic tissue changes induced by their chronic compression, continuous pathologic moisture and shift of tissues that determine local ishaemia. The aim of the article: to study clinical options and suppurative complications of decubitus ulcers in patients with type 2 diabetes mellitus (DM) in terms of insulin resistance (IR) in the context of combined treatment optimization. Materials and methods. Total sample of retro- and prospective analyses involved results of comprehensive treatment of 112 patients. Type 2 DM was diagnosed in 37 patients, I comparison group included 27 patients with decubitus ulcers without complications (I–III stages) and DM, with decubitus ulcers stage IV — II comparison group; and the control group included other 75 individuals. Results. The patients with type 2 DM (I comparison group) had considerable decrease in HOMA index of β-cell function and increased HOMA index of IR (8.31 ± 0.02, р < 0.01). Patients with type 2 DM with complicated decubitus ulcers (II comparison group) had more significant increase of circulating insulin indexes (p2 < 0.01), HOMA index of IR (p2 < 0.05), and considerable decrease on HOMA index of β-cell function (p2 < 0.05). The correlation analysis of HOMA-IR indicators and element concentration in the blood revealed the correlation only in patients with type 2 DM (I and II comparison groups): potent negative correlation (r = –0.72; p < 0.001) was revealed between the HOMA-IR and Mg2+ content in erythrocytes; intermediate negative correlation (r = –0.66; p < 0.01) — between HOMA-IR and Zn2+ concentration in the blood serum; and a negative one (r = –0.69; p < 0.01) — between HOMA-IR and Cr3+ level in the blood serum. Conclusions. The advantage of the proposed classification of decubitus ulcers of soft tissue and a sequence of comprehensive treatment is considering the features of pathogenesis, morphogenesis and clinical course of ulcers with complications that affect the course of healing and require appropriate strategies for the treatment of purulent wounds — TIME and DOMINATE, which, in our opinion, determines the possibility of the introduction into clinical practice of palliative care departments, other inpatient and outpatient health care facilities.
