title: Spectrum of primary immune deficiency at a tertiary care hospital.
abstract: OBJECTIVE
  To report various primary immune deficiencies diagnosed in children at a tertiary care hospital, their clinical manifestations and laboratory profile.
  
  
  METHODS
  Case records of children diagnosed to have primary immunodeficiency disorders over a period of 24 months at a tertiary care hospital in northern India were evaluated.
  
  
  RESULTS
  Twenty-seven children (M: F=3.5: 1) with mean age of 5.4 +/- 4.6 yrs (2 mo-16 yr) were diagnosed to have primary immunodeficiency. Thirteen children had chronic granulomatous disease (CGD), 4 had severe combined immunodeficiency (SCID), 4 had hypogammaglobulinemia, 2 had Ataxia telangiectasia, and one each had DiGeorge syndrome, Wiskott Aldrich syndrome, hyper IgM syndrome and leukocyte adhesion defect. Common mode of presentation were recurrent/ persistent pneumonia in 19, recurrent/ persistent diarrhea in 10, deep seated abscesses in 8, allergy in 3, disseminated tuberculosis infection in 2, extensive fungal infections in 2 and 1 each of disseminated cytomegalovirus (CMV) infection, disseminated BCG disease, otitis media and meningitis. Family history of sibling deaths was elicited in 2 families. Infectious agents were isolated in 16 cases.
  
  
  CONCLUSIONS
  From a single center 27 patients with primary immune deficiency could be identified by chart review, suggesting need for high index of suspicion for diagnosis of primary immune deficiency in India. Though the exact prevalence is not known there is need to make a registry to document the magnitude of problem of these disorders.
