Abstract
Introduction: The incidence of diabetes and its complications is increasing to staggering proportions. In 2014 the WHO estimated an overall prevalence of 422 million (8.5%) individuals with diabetes mellitus (DM). The diabetic neuropathy (DNP) which is one of complication of DM (50%) comprises a heterogeneous group of disorders that can cause neuronal dysfunction
throughout the human body. The optimal therapy involves: blood glucose level control, anticonvulsants, antidepressants and opioid administration, though it does not change pathogenic pattern. The recent studies suggest that the renin angiotensin aldosterone system (RAAS) plays a vital role in regulating glucose metabolism and blood pressure. In the same time the metabolic abnormalities associated with diabetes lead to activation RAAS, which might promote the formation of reactive oxygen species to lead the neuronal dysfunctions. Furthermore, TNFα is part of the response of the organism to hypertension and is originally described as one of the central mediators of inflammation trough the activation of transcription factor NFκB.
Methodology: The study is going on in parallel groups. The patients (enrolled on randomized principle) with DNP will be investigated. Group I with DNP was treated by aliskiren and group II with the same pathology, proceeding with the treatment without aliskiren but given telmisartan, for certainty of aliskiren efficacy. At the start of the trial and on completion of the six weeks period TNFα level and C-peptide are determined.
Findings: Telmisartan has less TNFα modulatory effects than aliskiren, namely, the symptoms of neuropathy as well as blood TNFα level and C-peptide level are not changed significantly.
Conclusion & Significance: TNFα is involved in DNP pathogenesis formation and clinical manifestation. Aliskiren amelioratessymptoms in DNP patients by modulatory impact on TNFα, so we have results for clinical and pharmacological analysis ofaliskiren application in DNP. The involvements of RAAS system in developments of DNP need further clinical analysis.
