Immunoglobulin deficiency

Twenty three patients with primary immunoglobulin(Ig) deficiency were seen during the last ten years. Nine had hypogamma globulinemia (hypo-Ig) and the rest, selective Ig deficiency. Most were in pediatric age group. There was preponderance of males with only one female. Clinical symptoms pertaining to gastrointestinal and sinupulmonary infections were most common. Complete absence of B cells was not observed in any patient with hypogammaglobulinemia. They could be typed as physiological in one patient, X-linked immunodeficiency in 2 patients and common variable immunodeficiency in the remaining six. Three patients with selective IgA deficiency were above 20 years of age. Two had only secretory IgA deficiency, confirmed by jejunal fluid examination and the rest had both secretory and serum IgA deficiency. Low IgM was seen in one patient. We see a spectrum of immunoglobulin deficiencies varying from subtle defects like absence of secretory IgA only, to severe depletion of all immunoglobulins. Therapy is still not ideal due to economic reasons.
