Seizures following renal transplantation in childhood

 Few studies have investigated the incidence of seizures following renal transplantation in childhood. The aim of this study was to determine this incidence and to identify risk factors. Retrospective casenote analysis was carried out on 119 transplants performed in 109 children over 10 years. Twenty-one transplants (in 20 children) were complicated by seizures, the majority of which occurred in the first 55 days after transplantation. Seizures were more common in the 5- to 10-year-old age group (P=0.03), but were no more common in those with a prior history of seizure (P=0.69). Their aetiology was predominantly multifactorial; hypertension (n=15), fever/infection (n=4) and acute allograft rejection (n=6) were commonly identified risk factors; 2 were secondary to intracerebral pathology. Most seizures were short lived, required minimal therapy and had a good long-term neurological outcome. In conclusion, seizures are relatively common following paediatric renal transplantation. Parents are now routinely counselled of this risk. Received: 11 March 1998 / Revised: 15 May 1998 / Accepted: 9 September 1998
