Diabetic foot ulcers, their characteristics, and trends in survival: Real world outcomes at a tertiary care facility in India.

AIMS: Characteristics of diabetes-related foot ulcers (DFU), association with recurrence and amputation are poorly described in the Asian Indian population. METHODS: A prospectively maintained database was reviewed to characterize DFU and its association with amputation and recurrence. RESULTS: Of 200 patients, 63.5 % were male, the median age was 62 years (Min-Max:40-86), and median BMI was 27.90 kg/m2 (Min-Max:18.5-42.7). Median duration of Diabetes mellitus was 15 years (Min-Max:2-43). Complete healing occurred at a median of three months (Min-Max:0.23-37.62). Amputation for the current ulcer was required in 43.4 % of individuals. Ulcer recurrence was documented in 42.4 % instances, 66.1 % evolving on the ipsilateral side. Previous amputation was associated with the risk of subsequent amputation (Adjusted OR-3.08,p-0.047). Median time to ulcer recurrence was 4.23 years among those with amputation, in contrast to 9.61 years in those with healing. Cardiovascular death was the commonest cause of mortality, followed by sepsis. At a median follow up of 6.08 years, mortality at 1,3,5 and 10 years was 2.5 %,2.5 %,8.2 % and 30.9 % respectively among those who underwent amputation versus 0 %,0 %,10.1 % and 24.5 % respectively for those who achieved healing. CONCLUSIONS: Patients with DFU in India incur amputations at rates higher than conventionally described. With previous amputation, subsequent amputation risk triples. Ten-year mortality is 25%-30 %. Underestimates of the burden of recurrence and mortality are consequential of limited follow-up.

Differentials in dietary intake of macro and micronutrients in patients with type 2 diabetes and foot ulcers: Observations from a pilot study.

BACKGROUND AND AIM: The dietary profiles of patients with type 2 diabetes mellitus (T2DM) from Southern India have been infrequently studied. We aimed to study the differences in dietary intake of macro and micronutrients in elderly patients of Type 2 diabetes mellitus (T2DM), with and without foot ulcers. METHODS: Elderly patients with T2DM and foot ulcers (n = 79; mean age: 60.6 years) and those without foot ulcers (n = 59; mean age: 55.0 years) were studied. Biochemical evaluation for measures of glycemia, lipids and albumin were done and staging of foot ulcers was done using Wagner's scale. A 24-hour dietary recall was administered to quantify the mean daily intake (MDI) of macro, micronutrients and trace elements from portion sizes of food items consumed and compared to the recommended dietary allowance (RDA) for Indians aged 55 years and above. RESULTS: In patients with T2DM and foot ulcers, the MDI of carbohydrates, fats and phosphorus were significantly higher whereas the MDI of proteins and micronutrients namely zinc, folic acid, iron and carotene were lower than the RDA. Elderly patients with nephropathy and longer duration of T2DM have higher odds of developing foot ulcers, when compared to patients without foot ulcers. CONCLUSION: Elderly patients with T2DM and foot ulcers were deficient in dietary intake of proteins and micronutrients inclusive of carotene, folic acid, zinc, and Iron. Clinical care, regular monitoring of dietary intake and appropriate correction of nutritional deficiencies will aid in the management of diabetic foot ulcers.
