title: [Analysis of comparative immunological profiles of intraocular fluid and serum samples in patients suspected of ocular toxoplasmosis or toxocarosis].
abstract: High seroprevalence of Toxoplasma and Toxocara spp. in populations of children and adults in Poland constitutes a significant risk of supradiagnosed parasitic eye infections. We described the clinical characteristics in relation to the analysis of comparative immunological profiles of T. gondii-specific antibodies in aqueous humour and serum samples in patients with reactivated retinochoroiditis, and of Toxocara spp. ones in cases with posterior granuloma, fibrotic and calcified tumor-like masses simulating retinoblastoma, detected by ophthalmoscopy and echography. Intraocular synthesis of specific IgG antibodies was detected in anterior eye chamber fluid in 1/2 and 2/3 of patients respectively, strongly suspected of ocular toxoplasmosis or toxocarosis. The evidence of a local production of specific antibodies in intraocular fluid shown by the Western blot seems to be a valuable immunodiagnostic method for a final confirmation of eye lesions of parasitic origin and crucial in the choice of an appropriate treatment regimen.
