The distribution and proportion of immunoglobulin-producing cells in palatine tonsil, including IgG and IgA subclasses, have been examined in chronic tonsillitis using an immunofluorescence method. Results obtained indicate that the percentage ratios of IgG1:IgG2:IgG3:IgG4 were 53.1:35.9:4.7:6.3. Higher percentages of IgG1- and lower percentages of IgG2-producing cells were found among 3 types of tonsillitis. Proportional ratios of IgA1:IgA2 were approximately 80:20, and a slight elevation of IgA2-producing cells was observed in chronic tonsillitis.

The authors report the case of a previously healthy 5-year-old boy who, 1 month after tonsillitis, presented severe aregenerative anemia, macrocytosis, and increased hemoglobin F associated with mild thrombocytopenia. Peripheral blood smear showed no significant alterations and bone marrow aspirate revealed markedly decreased red blood cell precursors. Etiological investigation showed elevated titers of Epstein-Barr virus antibodies (IgM anti-viral capsid antigen). Bone marrow biopsy showed no criteria for red cell aplasia and in situ hybridization revealed intracellular Epstein-Barr virus. Reticulocytosis emerged from days 10-17 of follow-up, together with rising hemoglobin. Mean corpuscular volume and hemoglobin F returned to normal 2 months later. Immunological study revealed partial IgG3 deficit that persisted after 1 year of follow-up.
