title: Analysis of immunoglobulin deficiency cases: a five year study.
abstract: A total of 734 serum specimens from various clinical disorders along with 100 control samples from healthy subjects were processed for estimation of serum IgG, IgA and IgM employing single radial immunodiffusion procedure. Immunoglobulin deficiency, either selective or combined was noted in 31 males and 24 females in all age groups. Of the 55 cases encountered it was secondary immunoglobulin deficiency which was seen on a larger scale and encountered in patients with Multiple myeloma (16 out of 32) followed by Leprosy (14 out of 250), Lymphoma (5 out of 43), Malaria (4 out of 137), Burns (4 out of 52), Rheumatoid arthritis (2 out of 69) and non lymphoreticular malignancies (1 out of 41) in decreasing order of frequency. Primary immunoglobulin deficiency was observed in nine cases comprising of six belonging to Idiopathic late onset immunoglobulin deficiency, two of dysgammaglobulineamia and a solitary case of Ataxia telangiectasia. Panimmunoglobulin deficiency was observed in six cases, 11 had a dual deficiency while 38 showed deficiency of an isolated class with selective IgA deficiency in 20 cases. Furthermore, one patient each had total absence of IgG or IgA while IgM was not detectable in seven patients. A high suspicion index along with a regular rapport between the clinician and the laboratory personnel is necessary in the diagnostic set up of immunoglobulin deficiency states.
