Trombocytosis in childhood relapsing nephrotic syndrome
Abstract
Background Thrombosis is a serious complication of nephroticsyndrome (NS). Long-term steroid treatment may induce
thrombocytosis in relapsing NS that may predispose to thrombosis.
Most children with idiopathic NS respond to steroids; however, a
substantial number of patients will relapse frequently and require
repeated high dose steroid therapy, thus increase the risk of
thrombocytosis.
Objective To compare the occurrence of thrombocytosis between
children with frequent relapses of NS (FRNS) and those with
infrequent relapses (IFRNS).
Methods We reviewed the medical records of children aged 1-14
years diagnosed as FRNS and IFRNS at the Department of Child
Health, Hasan Sadikin General Hospital Bandung from 2000-
2005. We excluded children with iron deficiency anemia,
hemolytic anemia, acute haemorrhage, malignancy, and those who
received cyclophosphamide.
Results There were 33 children (26 males, 7 females) with FRNS
and 33 children (27 males, 6 females) with IFRNS. The mean
platelet level of children with FRNS (517,909+165,670/ml) was
higher than that of children with IFRNS (416,272+145,763/ml)
(P=0.005). The occurrence of thrombocytosis in children with
FRNS (18) was higher than that of children with IFRNS (7)
(P=0.005).
Conclusion This study shows that thrombocytosis is more
common in FRNS than IFRNS, therefore we should take more
precaution to the occurrence of thrombosis in FRNS.
