Immunoglobulins and serum proteins in toxoplasmosis

Immunoglobulin levels in 47 children (age 13-20 years) with toxoplasmosis were compared with 46 age and sex matched controls. No significant difference was observed in mean serum immunoglobulin (IgG, IgA, IgM) levels between patients and controls but mean IgM levels were significantly (P) higher in children with acute toxoplasma infection. Total proteins were higher in patients while mean albumin and globulin levels were similar between the two groups. Estimation of serum immunoglobulins in young children with toxoplasmosis has no significance and should not be considered as an immunodiagnostic tool.
