Benefit of STR-based chimerism analysis to identify TA-GVHD as a cause of death: Utility of various biological specimens.

Transfusion-associated graft-versus-host disease (TA-GVHD) is a rare condition. It can occur after blood transfusion in immune-compromised and occasionally even in immune-competent patients, and is associated with a mortality rate of >90%. The diagnosis of TA-GVHD is often delayed because of its non-specific clinical features.

Vitamin D levels in Indian children with intrathoracic tuberculosis.

Background & Objectives: Deficiency of vitamin D, an immunomodulator agent, is associated with increased susceptibility to tuberculosis in adults, but only limited studies are available in the paediatric age group, especially regarding association of vitamin D with type and outcome of tuberculosis. We conducted this study to determine the baseline 25-hydroxy vitamin D levels in children suffering from intrathoracic tuberculosis and its association with type and outcome of tuberculosis.

Methods: Children with intrathoracic tuberculosis, diagnosed on the basis of clinico-radiological criteria, were enrolled as part of a randomized controlled trial on micronutrient supplementation in paediatric tuberculosis patients.
