Diabetic Foot Infections

The aim of the present research was to study the prevalence and severity of vitamin D deficiency in patients with diabetic foot infection. Patients were enrolled in two groups: diabetic patients with foot infection (n 125) as cases and diabetic patients without the infection as controls (n 164). Serum 25-hydroxyvitamin D (25(OH)D) was measured by RIA. Data were presented as means and standard deviations unless otherwise indicated and were analysed by SPSS. Results revealed that 25(OH)D (nmol/l) was significantly lower (40·25 (sd 38·35) v. 50·75 (sd 33·00); P < 0·001) in cases than in controls. Vitamin D inadequacy (25(OH)D < 75 nmol/l) was equally common in cases and controls (OR 1·45, 95 % CI 0·8, 3·0; P = 0·32), but cases had a greater risk of vitamin D deficiency (25(OH)D < 50 nmol/l) than controls (OR 1·8, 95 % CI 1·1, 3·0; P = 0·02). Risk of severe vitamin D deficiency (25(OH)D < 25 nmol/l) was significantly higher in cases than in controls (OR 4·0, 95 % CI 2·4, 6·9; P < 0·0001). Age, duration of diabetes and HbA1c were significantly higher in cases than in controls and therefore adjusted to nullify the effect of these variables, if any, on study outcome. The study concluded that vitamin D deficiency was more prevalent and severe in patients with diabetic foot infection. This study opens up the issue of recognising severe vitamin D deficiency ( < 25 nmol/l) as a possible risk factor for diabetic foot infections and the need for vitamin D supplementation in such patients for a better clinical outcome. This could be substantiated by similar data from future studies.

Vitamin D has been recognised as a potent immunomodulator and its deficiency is common in different population groups including patients with diabetic foot infection. Diabetic foot infection reflects the altered immune status of the host. As cytokine regulation plays a significant role in infection and wound-healing processes, the present study aimed to evaluate the association between vitamin D status and inflammatory cytokine profiles in patients with diabetic foot infection. The serum concentrations of vitamin D (25-hydroxyvitamin D), IL-1β, IL-6, TNF-α and interferon-γ (IFN-γ) were measured in 112 diabetic foot infection cases and 109 diabetic controls. Severe vitamin D deficiency (25-hydroxyvitamin D concentration < 25 nmol/l) was more common in cases than in controls (48·2v.20·5 %). Although age, duration of diabetes, HbA1C(glycosylated Hb) concentration and BMI were similar, cases had significantly higher concentrations of IL-6 (P≤ 0·001), IL-1β (P≤ 0·02) and TNF-α (P≤ 0·006) than controls. A significant negative correlation was also observed between 25-hydroxyvitamin D concentration and circulating concentrations of IL-1β (r− 0·323;P≤ 0·001) as well as IL-6 (r− 0·154;P≤ 0·04), but not between 25-hydroxyvitamin D and TNF-α and IFN-γ concentrations. Furthermore, a significant difference in IL-1β (P≤ 0·007) and IL-6 (P≤ 0·02) concentrations was observed in patients with severe 25-hydroxyvitamin D deficiency compared with patients with 25-hydroxyvitamin D concentration ≥ 25 nmol/l, and this difference was remarkable for TNF-α. In conclusion, severe vitamin D deficiency is associated with elevated inflammatory cytokine concentrations in diabetic patients, particularly in those with foot infection. A 25-hydroxyvitamin D concentration value < 25 nmol/l is suggested as the ‘cut-off’ for such immunological alterations in patients with diabetes mellitus.

AbstractThe incidence of vitamin D deficiency is high globally, and vitamin D supplementation draws particular attention. The objective of this study was to investigate the effects of stratified vitamin D supplementation in middle-aged and elderly individuals with vitamin D insufficiency in Beijing. A total of 448 subjects aged over 40 years old were selected from a community in Beijing. Among them, 100 middle-aged and elderly people with vitamin D insufficiency were randomly selected on a voluntary basis. They were further divided into control group and intervention group. The control group received health education and lifestyle guidance, and the intervention group received lifestyle guidance and vitamin D supplementation for nine months. The doses were stratified as follows: for vitamin D insufficiency, oral vitamin D3 supplement was given at 5000 IU/w; for mild vitamin D deficiency, oral vitamin D3 supplement was given at 10 000 IU/w; for severe vitamin D deficiency, oral vitamin D3 supplement was given at 15 000 IU/w. Safety evaluation was conducted after three-month treatment. The intervention group consisted of 8%, 62%, and 30% of cases who had vitamin D insufficiency, mild vitamin D deficiency, and severe vitamin D deficiency, respectively, which were similar with the control group. It showed that the blood 25(OH)D level increased significantly in the intervention group, from 14.30±4.30 ng/ml to 33.62±6.99 ng/ml (p<0.001), in contrast to insignificant change in the control group. Stratified vitamin D supplementation effectively increased the blood 25(OH)D level, as well as the number of cases with corrected vitamin D insufficiency or deficiency.

Background. Vitamin D deficiency is a common problem among patients on continuous ambulatory peritoneal dialysis (CAPD). Vitamin D supplementation leads to reduced serum parathyroid hormone levels and improved cardiovascular markers. Different doses and time intervals of oral vitamin D supplementation may differ in each patient on dialysis. The study aimed to evaluate the efficacy of weekly split and single dose of ergocalciferol at 60,000 IU on serum 25-hydroxyvitamin D (25(OH)D) among patients on CAPD. Methods. A randomized study was conducted among patients on CAPD with vitamin D deficiency or insufficiency (25(OH)D < 30 ng/mL). Patients were randomly assigned to two groups: the split dose group was given ergocalciferol 20,000 IU three times weekly and the single dose group was given ergocalciferol 60,000 IU once weekly for 8 weeks. Main outcomes measured serum 25(OH)D concentrations, serum calcium, serum phosphate, and intact parathyroid levels at 8 weeks after being enrolled. Results. Of 128 screened patients, 50 met the criteria for eligibility and were randomized. At 8 weeks after treatment, mean serum 25(OH)D concentrations significantly increased from baseline 22.7 ± 5.9 to 29.5 ± 9.5 ng/mL P = 0.004 in the split dose group and 22.9 ± 5.3 to 31.2 ± 12.3 ng/mL P = 0.003 in the single dose group. No significant change was found in increase of serum 25(OH)D between the two groups P = 0.561 . At the end of study, a similar proportion of patients in both groups reached the desirable serum concentration of 25(OH)D ≥ 30 ng/mL (60% in the single group vs. 40% in the split group, P = 0.258 ). No significant cases of hypercalcemia, hyperphosphatemia, or serious adverse events occurred during the study. Conclusion. Weekly single and split doses of ergocalciferol 60,000 IU achieved similar effects on serum 25(OH)D levels among patients on CAPD with vitamin D insufficiency or deficiency, suggesting that weekly single dose would be prescribed for adequate vitamin D repletion. This trial is registered with TCTR20200821005.

Purpose: To investigate the effect of weekly single high dose vitamin D supplementation on serum 25-hydroxyvitamin D [25(OH)D], and non-specific musculoskeletal pain in female nurses. Methods: In this prospective study in Kashan/Iran, from April 1, 2014, through September 30, 2014, the 150 nurses with vitamin D deficiency received the weekly pearls of 50,000 units of vitamin D3 for 10 weeks. The serum level of 25(OH)D was measured before and after supplement therapy. The subjects were also asked to complete the Extended Nordic Musculoskeletal Questionnaire. All analyses were conducted with SPSS version 16. Results: After 10 weeks of intervention there was [Formula: see text][Formula: see text]ng/mL increase in 25(OH)D. The 82 nurses (54.7%) had 25(OH)D in normal range, while the 68 nurses (45.3%) were still vitamin D deficient. Weight could explain 15.4% increase in 25(OH)D. Before intervention 135 (90%), of nurses reported musculoskeletal pain in at least one region, after intervention this number decreased to 72.7%. There was a statistically significant improvement in musculoskeletal pain in neck, shoulders, upper back, lower back, hips/tights, knees, and ankles/feet after intervention. Conclusions: The weekly single high dose of vitamin D for 10 weeks could resolve vitamin D deficiency in about half of the patients. Patients with non-specific musculoskeletal pain might benefit from vitamin D supplementation.

AbstractThe etiology of endemic rickets was discovered a century ago. Vitamin D is the precursor of 25-hydroxyvitamin D and other metabolites, including 1,25(OH)2D, the ligand for the vitamin D receptor (VDR). The effects of the vitamin D endocrine system on bone and its growth plate are primarily indirect and mediated by its effect on intestinal calcium transport and serum calcium and phosphate homeostasis. Rickets and osteomalacia can be prevented by daily supplements of 400 IU of vitamin D. Vitamin D deficiency (serum 25-hydroxyvitamin D <50 nmol/L) accelerates bone turnover, bone loss, and osteoporotic fractures. These risks can be reduced by 800 IU of vitamin D together with an appropriate calcium intake, given to institutionalized or vitamin D–deficient elderly subjects. VDR and vitamin D metabolic enzymes are widely expressed. Numerous genetic, molecular, cellular, and animal studies strongly suggest that vitamin D signaling has many extraskeletal effects. These include regulation of cell proliferation, immune and muscle function, skin differentiation, and reproduction, as well as vascular and metabolic properties. From observational studies in human subjects, poor vitamin D status is associated with nearly all diseases predicted by these extraskeletal actions. Results of randomized controlled trials and Mendelian randomization studies are supportive of vitamin D supplementation in reducing the incidence of some diseases, but, globally, conclusions are mixed. These findings point to a need for continued ongoing and future basic and clinical studies to better define whether vitamin D status can be optimized to improve many aspects of human health. Vitamin D deficiency enhances the risk of osteoporotic fractures and is associated with many diseases. We review what is established and what is plausible regarding the health effects of vitamin D.

Objectives: To evaluate the association of severe vitamin D deficiency with clinically important outcomes in children with septic shock. Methods: We enrolled children ≤17 years with septic shock prospectively over a period of 6 months. We estimated 25-hydroxyvitamin D [25 (OH) D] levels at admission and 72 hours. Severe deficiency was defined as serum 25 (OH) <10 ng/mL. We performed univariate and multivariate analysis to evaluate association with clinically important outcomes. Results: Forty-three children were enrolled in the study. The prevalence of severe vitamin D deficiency was 72% and 69% at admission and 72 hours, respectively. On univariate analysis, severe vitamin D deficiency at admission was associated with lower rates of shock reversal, 74% (23) versus 25% (3); relative risk (95% confidence interval [CI]): 2.9 (1.09-8.08), at 24 hours and greater need for fluid boluses (75 vs 59 mL/kg). On multivariate analysis, nonresolution of shock at 24 hours was significantly associated with severe vitamin D deficiency after adjusting for other key baseline and clinical variables, adjusted odds ratio (95% CI): 12 (2.01-87.01); 0.01. Conclusion: The prevalence of severe vitamin D deficiency is high in children with septic shock admitted to pediatric intensive care unit. Severe vitamin D deficiency at admission seems to be associated with lower rates of shock reversal at 24 hours of ICU stay. Our study provides preliminary data for planning interventional studies in children with septic shock and severe vitamin D deficiency.
