Clinical and Hematological Correlates of Hemolytic Anemia in Diabetic Foot Ulcer Patients: A Prospective...

Background Diabetic foot ulcers (DFUs) are a significant complication of diabetes mellitus and are often accompanied by various complications including hemolytic anemia. However, the clinical and hematological correlates of hemolytic anemia in patients with DFU remain poorly understood. This prospective observational study aimed to investigate the clinical and hematological correlates of hemolytic anemia in patients with DFU and to elucidate the potential mechanisms underlying this complication and its impact on wound healing. Methodology A total of 148 adult patients diagnosed with DFUs were enrolled in this study. Clinical and demographic data were collected, including age, sex, duration of diabetes, glycemic control status, presence of comorbidities, and foot ulcer characteristics. Hematological parameters, including complete blood counts, reticulocyte counts, and hemolysis markers, were measured at baseline and during the follow-up visits. Statistical analyses were conducted to assess the prevalence of hemolytic anemia, identify the demographic and clinical factors associated with its presence, and explore its relationship with wound healing outcomes. Results The prevalence of hemolytic anemia among patients with DFU was 41.9%. Patients with hemolytic anemia had a longer duration of diabetes (mean duration: 8.3 ± 2.1 years), higher glycated hemoglobin (HbA1c) levels (mean: 9.2% ± 1.5%), and a greater burden of comorbidities than those without hemolytic anemia. Hematological analysis revealed significant differences in hemoglobin levels, red blood cell indices (mean corpuscular volume: 89.6 ± 5.2 fL), and markers of hemolysis (mean lactate dehydrogenase level: 325 ± 45 U/L) between DFU patients with and without hemolytic anemia. Furthermore, correlations were observed between hematological parameters and wound healing outcomes, suggesting potential implications for clinical management. Conclusions This study provides valuable insights into the clinical and hematological correlates of hemolytic anemia in patients with DFU. These findings highlight the importance of recognizing and addressing hematological abnormalities in the management of DFU, with potential implications for optimizing wound healing and improving clinical outcomes.
