BACKGROUND
Diabetic neuropathy is associated with risk factors for macrovascular diseases and other microvascular complications. Alpha-lipoic acid (ALA) administration has been reported to improve metabolic abnormalities and ameliorate peripheral polyneuropathy in diabetic patients. In addition, ALA improves endoneurial nutritive neural blood flow and nerve conduction velocity in diabetic rats. But it is not clear whether ALA has a preservation effect on microvasculature in addition to the effect on intraepidermal nerve fibers (IENFs). We investigated the effect of ALA on intraepidermal nerve fiber density (numbers/mm) and cutaneous capillary length in streptozotocin-induced diabetic rats. METHODS: The rats were randomly divided into 3 groups: diabetes without diet control, diabetes with diet control, and diabetes with ALA treatment. Diabetes was induced by a single intraperitoneal injection of streptozotocin (60 mg/kg) and the effect of ALA treatment was assessed by IENF immunostained with protein gene product 9.5 and by quantification of total cutaneous capillary length with mouse anti-rat reca-1 immunostaining. RESULTS: The value of IENF density significantly increased in ALA treatment group compared with other groups (P < 0.05). Quantification of microvascularity was also significantly increased in ALA treatment group compared with other groups (P < 0.05). CONCLUSION: The results of this study suggest that ALA administration in diabetic rats may be beneficial in the prevention of peripheral neuropathy associated with improvement of microvascularity. And the symptomatic amelioration after ALA treatment may be attributed to this morphological improvement.

AbstractAbstract PDF
BACKGROUND
Peripheral neuropathy is a common complication of diabetes mellitus, contributing the greatest morbidity and mortality and impairing the quality of life. Recently the receptor of erythropoietin (Epo) was proven to be expressed in neuronal cell and recombinant human Epo (rhEpo) has been shown to have neuroprotective and neurotrophic potential in peripheral neuropathy. But there is no report about baseline Epo level in blood before rhEpo treatment with diabetic peripheral neuropathy. METHODS: From Jan. 2000 to Sep. 2006, diabetic patients were reviewed about Epo level in blood, anemia, and peripheral neuropathy in Chonbuk National University Hospital. And we compared the mean value of baseline Epo level in diabetic patients with anemia according to the peripheral neuropathy. RESULTS: The mean value of Epo of patients with peripheral neuropathy was lower than that of patients without peripheral neuropathy (16.3 +/- 7.1 vs 26.1 +/- 29.7 mU/mL, P < 0.05). There was no significance in the correlation between hemoglobin and Epo level in diabetic patients with anemia irrespective of presence of peripheral neuropathy (r = -0.02, P = 0.81). CONCLUSION: We suggest that decreased Epo level in blood is possible to be an additional cause in the development of peripheral neuropathy. However, simultaneously another possibility that neuropathy causes reduced Epo level should be considered, so further studies are warranted in this field.

AbstractAbstract PDF
Diabetic foot ulcer is a common complication in diabetic patients and the outcome of foot ulcer depends on the severity of ulcer and combined infection such as osteomyelitis. So antibiotics targeting Gram positive cocci including Staphylococcus aureus have been used frequently. However, during the antibiotic therapy, diverse adverse reactions could be happened including red man syndrome, chest pain, hypotension, thrombocytopenia, neutropenia and drug eruption. Among these reactions, hematologic adverse events such as pancytopenia are rare and it could be lethal if happened. This article reports a case of pancytopenia associated with vancomycin in treating the diabetic patient with infected foot ulcer.
