[Clinical course of congenital toxoplasmosis in children]

Hundred eleven children with the congenital toxoplasmosis were treated at the Department of Infectious and Parasitic Diseases in Childhood in 1979-1988. Multi-symptomatic toxoplasmosis has been diagnosed in 35 cases, ocular form in 65, oligosymptomatic in 6, and asymptomatic in 5 cases. Clinical symptoms suggesting congenital toxoplasmosis was seen in the majority of children (63 cases) in the first year of life and the disease was diagnosed in 50% of cases (33 children) at this age. Congenital toxoplasmosis in the group of 78 children has been diagnosed later. The majority of cases was ocular form. Diagnosis of the oligo- and asymptomatic congenital toxoplasmosis is possible in the first year of life, only. A titre of antibodies is exclusively an indicator of the immunologic response, not a severity of infection and does not contribute to the prognosis. Antitoxoplasma drugs were administered to 102 children including 33 under the first year of life. Pyrimethamine, sulphonamides, and spiramycin were used in the treatment. Dosage, duration of therapy, and way of administration have been established individually in dependence of patients age and clinical form of the congenital toxoplasmosis. Two out of 35 children with multi-symptomatic congenital toxoplasmosis died whereas 13 demonstrate psychomotor retardation of significant degree despite the fact that 11 of them were treated in the first year of life.

[Observations of children with chorioretinitis in congenital toxoplasmosis]

Hundred eleven children with congenital toxoplasmosis were followed up in the Department of Infectious and Parasitic Diseases in Childhood, Medical Academy in Warsaw, within 1979-1988. Ocular changes found in 91 children including chorioretinitis in 86 microphthalmia in 7, ophthalmic nerve atrophy in 15, vitreous body inflammation in 5, and cataract in 4. Only in 16 children the diagnosis was performed in the first year of life. In 15 children the recurrence of inflammatory process, most frequently in the time of puberty, was noted; twice in 5 of them. It was independent on the treatment which was previously administrated. Serological tests in ocular form of congenital toxoplasmosis do not indicate the dynamic changes in the inflammatory process. It is very important that small children are examined early and the treatment is started in the first year of life.

[Results of acyclovir treatment of chickenpox and herpes zoster in children with immune tolerance]

Acyclovir was used for the treatment of Varicella-zoster virus infections in 53 children (10 neonates and 43 children aged between 2 an 15 years) with immunological system deficiency hospitalized at the Department of the Infectious Diseases of Childhood in the Medical Academy in Warszawa. The obtained results of therapy were favourable except one fatal case of the child with visceral dissemination of the virus prior to acyclovir treatment. Compared with other antiviral agents used by the authors previously, acyclovir proved to be the most effective.
