Chronic peritoneal dialysis (CPD) is a common form of renal replacemen
t therapy in children. Recent studies suggest that immunological abnor
malities, in particular hypogammaglobulinemia, may develop in children
and infants on peritoneal dialysis. We report an infant maintained on
CPD who died of gram-negative sepsis. At post-mortem examination, he
was noted to have severe panhypogammaglobulinemia.
