ABSTRACT

Background: Vitamin D deficiency is present in India in epidemic proportions despite plenty of sunshine. Reduced plasma 25(OH) D concentrations as a diagnostic marker of vitamin D deficiency have been in past decade associated with several well-established risk factors for ischaemic stroke, such as arterial hypertension, thrombosis, atherosclerosis. The aims and objectives of this study was to compare the serum 25(OH) D levels between the first ever acute stroke patients and healthy controls.Methods: A cross-sectional, case control study was conducted in a tertiary care hospital in New Delhi situated in north India. Serum 25‑hydroxyvitamin D (25(OH) D) levels in 85 patients of ischemic stroke, presenting within 7 days of onset of stroke was measured and was compared with 70 age and gender matched controls.Results: The mean age was 61.02±11.58 years and 58.63±11.28 years in cases and controls respectively. Females constituted 37.6% of the total number of cases and 43.4% of the controls. The age and gender-distribution were comparable between the cases and controls. The median value (IQR) of serum 25(OH) vitamin D level was 7.94 ng/mL (4.59-14.00) in the cases and it was 8.82 ng/mL (5.59-14.70) in the controls. The difference between the serum 25(OH) vitamin D levels of the two groups was not found to be statistically significant.Conclusions: There is a high prevalence of biochemical hypo-vitaminosis D in apparently healthy Indians of all age and sex groups despite adequate sunshine. There is no association between low vitamin D levels and stroke.

ABSTRACT

Essential thrombocythemia [ET] is a rare myeloproliferative disorder occurring predominantly in the elderly population. Its occurence in the pediatric age group is even more rare. We report a 1 3-year-old girl who presented with isolated cerebral venous thrombosis and was diagnosed with essential thrombocythemia. Family screening for any thrombocytosis was 20 negative. With no secondary cause apparent for persistent thrombocytosis, we looked for the JAK2 mutation, but the result was negative. In contrast to linkage of JAK2 mutation positivity with increased thrombotic risk, our case showed that thrombosis can occur in the absence of JAK2 mutation in a case of essential thrombocythaemia. The indications for treatment and the best treatment of children with ET are currently not known, and guidelines for the management of children with ET are needed. Adult patients have near-normal life expectancy because of the low rate of leukemic conversion, but no child has been monitored long enough to assess prognosis
