ABSTRACT
Background: Dapsone treatment may reduce HbA1c levels in patients with diabetes. Aims: To assess the prevalence and characteristics of dapsone associated reduction of HbA1c in patients with Hansen’s disease. Methods: A retrospective data review of outpatient and inpatient charts of consecutive patients with Hansen’s disease and type 2 diabetes mellitus was conducted over two years from January 2014 to January 2016 at the Department of Dermatology, CMC Vellore, India. Results: Of the 245 patients with a confirmed diagnosis of Hansen’s disease who were on oral dapsone 100 mg/day as part of their treatment regimen, 49 patients had diabetes and were eligible for the study as per predetermined inclusion criteria. Of these, 35 subjects (71%) had an HbA1c discordantly lower than the corresponding mean plasma glucose levels. Patients with discordant HbA1c levels were more likely to be male and to have a higher RBC mean corpuscular volume (MCV). A greater reduction in HbA1c levels was seen during the initial 3 months of therapy of dapsone treatment. Limitations: The small sample size and retrospective design were limitations of this study. Also, we did not analyze the role of methemoglobinemia or the utility of alternative measures of glycemic control in these patients. Conclusion: We describe a high prevalence of dapsone associated inappropriate HbA1c lowering in type 2 diabetes mellitus patients. This may have serious implications for the management of diabetes in patients on therapy with dapsone.
ABSTRACT
Carbon tetrachloride feeding (3.2g/kg/72hr) for one month increased significantly the serum and tissue lipid profile and deranged the enzyme levels viz; alkaline phosphatase, alanine transaminase, aspartate transaminase, glutathionze reductase, HMGCoA reductase, catalase, gluc.6.PDH and malic enzyme in rats. Simultaneously the lipid peroxidation level in liver was also raised. On administration of garlic oil and its major nonpolar fraction (NPFGO) and a flavonoid isolated from the bark of Ficus bengalensis Linn, viz; leucopelargonin derivative respectively to different groups(100mg/kg/day) the deleterious effects of CCl4 were significantly ameliorated. The liver damage by CCl4 was satisfactorily prevented by these samples as effectively as Vit. E (50 mg/kg/day). The results prove that important nutraceuticals (phytonutrients) like bioflavonoids and theols i.e. allylic sulphide rich fractions give protection from toxins like CCl4. The order of beneficial effects of the drugs are Leucopelargonin > NPFGO > Garlic oil and their effects are comparable to that of vitamin E used at a minimal dose.
