Brief summary

The goal of this clinical trial is to see the effect of vitamin D3 supplementation on cardiac autonomic nerve function in male epileptic patients with hypovitaminosis D that weather vitamin D improves heart rate variability or not. The main questions it aims to answer are: 1. Does vitamin D improves cardiac autonomic tone in male epileptic patients? 2. Does vitamin D improves heart rate variability in male epileptic patients? It is a self control trial. Participants will: 1. undergo through baseline HRV testing 2. start to take vitamin D3 50000 IU once in a week for 8 weeks b) visit the university after 8 weeks for post interventional HRV testing . Researcher will compare the pre test and post test value of HRV testing.

Detailed description

In epilepsy, there is a shifting of autonomic balance toward sympathetic dominance & heart rate variability (HRV) is reduced which can be detected by interictal heart rate variability (HRV) testing. Patients treated with anti-epileptic drugs (AEDs) are suffered from one of its major adverse effects of vitamin D3 deficiency or hypovitaminosis D due to enzyme inducing effect of AEDs. Vitamin D3 is a neuroprotective hormone that modulates autonomic balance and regulates sympathetic and parasympathetic nervous systems. Vitamin D3 deficiency is also associated with the risk of reduced HRV. Administration of vitamin D3 in vitamin D3 deficient epileptic patients may improve their cardiac autonomic nerve function that can be interpreted by HRV.

Design outcomes

Primary

MeasureTime frameDescription
Vitamin D3 supplementation has effects on cardiac autonomic nerve function in male epileptic patients with hypovitaminosis D.8 weeksIn epilepsy, cardiac autonomic nerve function is altered which can be measured by heart rate variability test(HRV). HRV is reduced in epilepsy. Vitamin D3 supplementation in patients with epilepsy will improve their cardiac autonomic nerve function which can be detected by measuring various parameters of HRV test such as SDRR, LF(Low frequency).
