Total serum IgE, and Strongyloides - specific IgG and IgA antibodies were studied in 27 patients with parasitologically proven strongyloidiasis. Clinical manifestations in this case series were investigated by a restrospective study of the patient's records. Total serum IgE levels were elevated (greater than 250 IU/ml) in 59% of the patients (mean concentration = 1364 IU/ml). Parasite - specific IgG and IgA antibodies were detected by ELISA in the serum of 23 (85.2%) and 21 (77.8%) patients, respectively. Elevated serum IgE and clinical manifestations were not useful indexes of the presence of strongyloidiasis. On the other hand, our results support the view that serologic tests, particularly ELISA for detecting Strongyloides - specific IgG antibodies, can be usefully exploited for diagnostic purposes in strongyloidiasis.

— Serum immunoglobulin A (IgA), immunoglobulin G (IgG), and immunoglobulin M (IgM) levels were determined on 245 patients with carcinoma of the head and neck and on 92 controls. Ratios of these levels were calculated for each subject. The patients with cancer demonstrated elevated serum IgA levels ( P <.0001) and elevated IgA/IgM and IgA/IgG ratios ( P <.05). No differences were noted when the IgM/IgG ratios were compared between the cancer and the control groups. These observations are offered as evidence that previously reported elevations of serum IgA levels in patients with carcinoma of the head and neck are not merely an index of nonspecific increased immunoglobulin production in these patients.

ABSTRACT We report an 8-year-old boy with AIDS, extremely elevated serum immunoglobulin G (IgG) concentration and IgG kappa [IgG(κ)] and IgG lambda [IgG(λ)] paraproteinemia. This paraproteinemia partially responded to highly active antiretroviral therapy. This case emphasizes the importance of controlling B-cell activation.
