Predictors of Diabetic Foot Outcome in Chronic Kidney Disease Patients

About 537 million adults are living with diabetes mellitus (DM). This number is predicted to rise to 643 million by 2030 . Diabetic foot (DF), being one of the most prevalent, severe, and costly complications of DM. It is primarily characterized by skin infections, ulcers, or destruction of deep tissues below the ankle joint. It is commonly associated with neuropathy or vascular disorders in the lower extremities, and in severe cases, it may involve muscles and bones . Ultimately, 19% to 34% of patients with diabetes will suffer from DF during their lifetimes . Around 20% of DF patients may require lower limb amputations, which can be either minor (below the ankle joint) or major (above the ankle joint), and sometimes both . Individuals with diabetic neuropathy and Chronic kidney disease (CKD) are 15 times more likely to have a non-traumatic lower extremity amputation compared to those with DM alone . The incidence of DF and its evolution appear to be proportionally related to the stage of CKD . One of the most important causes is vascular calcification, which is common in patients with atherosclerosis, DM, CKD, and elderly . Various factors, including age, gender, infection severity, local ischemia, diabetes duration, neuropathy, and blood sugar control, are considered potential predictors for DF outcome. However, there remains a lack of complete understanding regarding the most significant factors and their respective impact on the outcome .
