Abstract

Leczenie nawrotu zespołu nerczycowego po transplantacji nerki jest trudne i w znacznej części przypadków nieskuteczne. Stosowane dotąd metody leczenia - nasilenie immunosupresji oraz powtarzana plazmafereza - nie są skuteczne u około połowy chorych.
W przedstawianym przypadku 5,5-letniego pacjenta z natychmiastowym nawrotem zespołu nerczycowego po transplantacji po wykonaniu 18 zabiegów plazmaferezy stwierdzono "zależność" choroby od wymiany osocza - po zabiegu białkomocz zmniejszał się i ponownie zwiększał.
Do leczenia włączono rituximab w dawce 4 × 375 mg/m2 i.v. pod kontrolą liczby komórek B CD19. Uzyskano długotrwałą (8-miesięczną) remisję, której towarzyszyła deplecja komórek B CD19 z krążenia. Nie odnotowano działań niepożądanych tego leczenia.
