Skewed TCR Alpha, but not Beta, Gene Rearrangements and Lymphoma Associated with a Pathogenic TRAC Variant.

We report a non-consanguineous family from North-west India in which 3 siblings succumbed to a rare variant of combined immunodeficiency. All three had similar clinical and immunological profiles. However, the youngest child also developed Non-Hodgkin lymphoma in infancy.

Clinical, Immunological, and Molecular Profile of Chronic Granulomatous Disease: A Multi-Centric Study of 236 Patients From India.

Background: Chronic granulomatous disease (CGD) is an inherited defect in phagocytic respiratory burst that results in severe and life-threatening infections in affected children. Single center studies from India have shown that proportion of autosomal recessive (AR) CGD is more than that reported from the West. Further, affected patients have high mortality rates due to late referrals and difficulties in accessing appropriate treatment.

Monocyte platelet aggregates in children with Kawasaki disease- a preliminary study from a tertiary care centre in North-West India.

Background: Platelet activation is an integral part of pathogenesis of Kawasaki disease (KD). However, there is paucity of literature on flow-cytometry based assessment of platelet activation in KD. We aimed to analyse monocyte-platelet aggregates (MPAs), one of the sensitive markers for platelet activation, by flow cytometry in children with KD.

Clinical and Genetic Profile of X-Linked Agammaglobulinemia: A Multicenter Experience From India.

Background: There is paucity of literature on XLA from developing countries. Herein we report the clinical and molecular profile and outcome in a multicenter cohort of patients with XLA from India.

Methods: Data on XLA from all regional centers supported by the Foundation for Primary Immunodeficiency Diseases (FPID), USA and other institutions providing care to patients with PIDs were collated.

Recent advances in chronic granulomatous disease.

Chronic granulomatous disease (CGD) is an inherited defect of phagocyte function due to defective NADPH oxidase. Patients with CGD are not able to effectively clear the infections because of the defect in the phagocyte production of oxygen free radicals and are prone to recurrent bacterial and fungal infections. Inflammatory complications are also noted in CGD such as colitis, non-infective granulomas causing gastrointestinal or urinary tract obstruction, hemophagocytic lymphohistiocytosis, and arthritis.

Fc-gamma receptor expression profile in a North-Indian cohort of pediatric-onset systemic lupus erythematosus: An observational study.

Background: Polymorphisms in the Fcγ-receptor (FcγR) have been associated with increased susceptibility to systemic lupus erythematosus (SLE). There is a paucity of data on FcγR expression pattern in pediatric subjects with SLE. The aim of the study was to assess the expression of various FcγRs by flow cytometry in children with pediatric-onset SLE (pSLE).

Vertebral Osteomyelitis and Acinetobacter Spp. Paravertebral Soft Tissue Infection in a 4-Year-Old Boy With X-Linked Chronic Granulomatous Disease.

Vertebral osteomyelitis is known to occur in chronic granulomatous disease, a phagocytic disorder and the etiology is usually a fungus. Indolent spread of fungal infection from lungs to adjacent ribs and vertebra often results in persistent pneumonia and vertebral deformities. We report a 4-year-old boy with chronic cough and kyphosis, who had a fungal vertebral osteomyelitis and Acinetobacter spp.

Isothiocyanates: a class of bioactive metabolites with chemopreventive potential.

In recent years, growing interest has been focused on the field of chemoprevention using natural therapies. The reason to turn toward "natural" remedies is associated with diverse beneficial pharmacological properties of natural compounds. Isothiocyanates (ITCs), the major pharmacological active constituents of cruciferous vegetables, are derived from the enzymatic hydrolysis of glucosinolates (GSLs).
