RESUMO
Serum samples obtained from 25 patients of mycetoma caused by Madurella mycetomi in 18, Streptomyces somaliensis in 5, Streptomyces madurae and streptomyces palletierii from 1 each and also from 25 healthy controls were evaluated for immunoglobulins IgG, IgM and IgA by radial immunodiffusion method using tripartigen plates. All the three classes of immunoglobulins showed increased concentration in cases of mycetoma by M. mycetomi and S. pelletierii. The raised levels of IgG and IgM in cases of mycetoma caused by S. madurae and S. somaliensis where bones were involved, were not statistically significant. IgA was consistently high in all cases of mycetoma irrespective of causative agent and tissue involved. These alterations may possibly reflect relatively poor IgG and IgM response in individuals with extension of mycetoma lesion to bones.

Among the various techniques developed for the detection of platelet antibodies, the platelet suspension immunofluorescence test has been reported to be simple, sensitive and reproducible, and therefore more clinically useful than other techniques available. An initial evaluation of the test was carried out for the detection of platelet autoantibodies in ten cases of idiopathic thrombocytopenic purpura. The indirect PSIFT was found to be positive in 60%. The technical aspects of the test and the problems encountered are discussed.
