Biochemical parameters of oxidative stress markers such as plasma malondialdehyde (MDA), RBC glutathione (GSH) would be performed at baseline (before pyridoxine administration) and 8 weeks after intervention.
The study will follow the principles of the Declaration of Helsinki and of the World Medical Assembly. Patients will be informed about the study in easy language and then informed consent will be taken. This study has no potential risk to the patients. Confidentiality will be strictly maintained.
