Background: Anemia is prevalent among patients with T2DM with DFU. However, there is limited research on the relationship between Hb level and DFU.
Objective: To investigate the characteristics and relationship between Hb level and prognosis in patients with DFU.
Materials And Methods: A total of 212 patients with T2DM were included and grouped according to the presence (n = 105) or absence (n = 107) of DFU. The independent t test and multiple logistic regression analysis were used to analyze the effect of different factors on the occurrence of anemia in patients with DFU and whether Hb level could be used to predict prognosis.
Results: There were significant differences in clinical indicators that directly or indirectly contributed to anemia in patients with DFU (P < .05). Hb level was independently associated with DFU (OR, 0.899; P < .05). Hb levels were significantly decreased in patients aged 65 years or older (P < .05). Mild anemia was prevalent among most patients with DFU (59.62%). Hb level decreased with the severity of foot ulcer (P < .05) and was correlated with the duration of diabetes (R2 = 0.653; P < .05). The AUC value was 0.82, with a cutoff value of 122.5 g/L to identify patients with DFU at high risk of adverse outcomes.
Conclusion: Anemia is common in patients with DFU. Anemia is a marker of DFU severity, and Hb level can predict poor prognosis in patients with DFU.

Hyperbaric Oxygen Therapy Combined With Standard Wound Care Versus Standard Wound Care Alone in Patients With Diabetic Foot Ulcers: A Prospective Comparative Study.

Background Non-healing diabetic foot ulcers (DFUs) are significant risk factors for amputations. Though the available literature suggests that adjuvant hyperbaric oxygen therapy (HBOT) fastens the healing process and reduces the risk of amputations, its overall evidence in the reduction of amputation remains controversial. Thus, the present study aimed to compare the efficacy and safety of adjuvant HBOT and standard wound care (SWC) with SWC alone in patients with DFUs.

Objectives: Diabetic foot ulcers (DFU) are one of the most serious chronic diabetes related complications. Since medial arterial calcification (MAC) can be present in patients with a DFU, toe pressure (TP) measurements are advised to grade potential ischemia. However, the value of TP to predict clinical outcomes in this group of patients is poorly understood.

Limited data are available about the epidemiological characteristics and the risk factors for amputation, particularly in developing countries from Asia, especially in China. We aim to investigate the age features of patients with Type 2 diabetic foot ulcers (DFUs) and analyze the critical influencing factors predicting lower extremity amputation and major amputation. Data were retrieved from the electric medical record system to identify patients aged > 18 years with Type 2 DFU from January 1, 2017, to December 31, 2023.

Aim: To assess the effects of several adjuvant therapies (AT) commonly used in the treatment of diabetic foot ulcers (DFU). The present meta-analysis was designed to support the development of the Italian Guidelines for the Treatment of Diabetic Foot Syndrome.
Methods: A Medline and Embase search were performed up to May 20th, 2024 collecting all RCTs including diabetic patients or reporting subgroup analyses on diabetic patients with DFU comparing AT with placebo/standard of care (SoC), with a duration of at least 12 weeks.

Diabetic Foot Ulcer (DFU) is a major complication of diabetes that mostly affects the lower extremities, with a high incidence and recurrence rate in approximately 15% of patients with diabetes. The complexity of diabetic wounds poses a substantial challenge for clinical recovery, underscoring the need to investigate novel therapeutic approaches. Medicinal plants have been used to treat ulcers for centuries.
