An Epidemiological Case Control Multi-centre Trial on Cerebral Venous Sinus Thrombosis in Western Maharashtra, India

Cerebral Sino-Venous thrombosis (CSVT) is common in India; this country has a heterogeneous population. Genetically and physio-gnomically this population differs in their diet as well as in their environment. Despite these differences CSVT has been described from all quarters of India; a common factor embracing all these patients could be nutrition.

An epidemiological, case- control, multi-centre trial was carried out in patients of CSVT. A common factor underlying this could be nutrition which has not been highlighted in several studies. Hence, we studied the nutritional aspects of these patients.

63 patients of CSVT and 62 controls enrolled prospectively and followed for a year were investigated with special emphasis on their nutritional status.

The triceps skin fold thickness, energy baseline, serum Proteins, Albumin, Hemogram and Platelet counts were lower in patients than in the controls while serum Homocysteine, carbohydrates and fats were higher in patients than in controls.

The results of this study confirm nutritional deficiencies in patients of CSVT and it begs the question of whether nutrition in any way is causal in CSVT. Larger multi-centric trials will help establishing causality. The study also shows that routine evaluation of thrombophilia factors and immunological tests are not necessary in CSVT.
