BACKGROUND:: Currently, it is reported that statins may be useful in the treatment of diabetes mellitus foot ulceration. The aim of this study was to evaluate treatment of the wounds in streptozotocin-induced diabetic rats with local atorvastatin.
METHODS:: Two 15 x 15 mm-sized wounds were created in 28 streptozotocin-induced rats. A total of 56 diabetic wounds were studied in 8 groups (n = 7). No treatment was administered in the first and second groups, which lasted for 7 and 14 days, respectively. Third and fourth groups consisted of diabetic rats that were administered 1:1 mixture of lanolin and vaseline therapy for 7 and 14 days, respectively. One percent statin plus 1:1 mixture of lanolin and vaseline was used in the fifth and sixth groups for 7 and 14 days, respectively; and in seventh and eighth groups, 5% statin plus 1:1 mixture of lanolin and vaseline therapy was used for 7 and 14 days, respectively. On the 7th and 14th days, state of the wound healing was observed, and the percent of wound healing was determined by measuring its size and by performing a histopathologic study. The statistical analyses were performed by Mann-Whitney U test, using SPSS 14.0 software.
RESULTS:: On the 14th day, the rates of wound healing in the first, second, third, and fourth groups were 14%, 40%, 96.59%, and 96.51%, respectively. This ratio was calculated by the formula healing ratio (%) = 100 x (1-wound area/initial wound area). Accordingly, in the multiple comparisons, the rates of wound healing were found to be significantly higher in the diabetic rat groups administered 1% and 5% atorvastatin compared with those administered a mixture of lanolin-vaseline and the untreated group (for comparison each one P < 0.001).
CONCLUSIONS:: Local atorvastatin therapy may be useful for healing the wounds in diabetic rats. Further clinical and experimental studies are needed to confirm these results.
Re: Topical Atorvastatin in the Treatment of Diabetic Wounds
Sounds promising, but has anyone actually used it one humans with improved results? Our local compounding pharmacy says they can fabricate it at $25.00 or so a tube and I am very tempted to use it on some of the folks who have been slow healing and who can't afford Regranex at $350 or so for 15gm.
Background: Diabetic foot ulcers (DFUs) are common complications of diabetes mellitus (DM), with a complex pathogenesis. Treatment is difficult and no single treatment with measurable clinical impact is available. In the present clinical pilot trial, we investigated whether statins could be of use against some of the pathogenic factors in DFUs.
Methods: Thirteen diabetic patients (10 men; 11 with Type 2 DM; mean age 64 years; mean duration of DM 18 years) with neuropathic DFUs <4 months were randomized to treatment with either 10 mg (six patients; six ulcers) or 80 mg (seven patients; nine ulcers) atorvastatin for 6 months in addition to conventional DFU care (i.e. prompt debridement, DFU pressure relief, and management of any underlying infection).
Results: There were no significant differences in background factors (i.e. HbA1c 8.9%, micro- and macrovascular complications, concomitant medications) or DFU characteristics (duration, surface area, grading) between the two groups. All ulcers in the group receiving 10 mg atorvastatin healed, compared with six of nine ulcers in the group receiving 80 mg atorvastatin (NS). However, two previously healed DFUs recurred and six new DFUs developed in the low-dose group compared with none and one, respectively, in the high-dose group (P = 0.048). There was a significant decrease in C-reactive protein (−1.5 mg/L; P = 0.044) and a non-significant trend towards beneficial effects on lipids and the ankle–arm blood pressure index in the high-dose compared with the low-dose group.
Conclusions: We observed a possible beneficial effect of 6-months high-dose atorvastatin on DFUs, which should be tested in appropriately sized prospective studies.
