Abstract
Introduction: Febrile convulsion (FC) is the most common seizure disorder in childhood. Few studies
focused on epidemiologic characteristics of urinary tract infections accompanied by FC.
Objectives: To evaluate prevalence and incidence rates of FC among children with urinary tract
infection.
Patients and Methods: An observational study in epidemiology was performed in nephrology clinic of
a tertiary children hospital from June 2002 to 2016. Totally 1242 cases were followed and those aged
6-60 months enrolled in the study. Demographic characteristics were compared between patients
with and without FC.
Results: 784 cases including 704 girls (89.8%) and 80 boys (10.2%) enrolled. Twenty-five patients
(3.18%) presented with FC. FC occurred in 25 of 503 cases (5%) with febrile urinary tract infection.
Twenty girls and 5 boys were in FC and 684 girls and 75 boys were in non-FC groups (P= 0.1). The
average age in FC and non-FC groups were 15.52±8.4 and 25.16± 16 months respectively (P=0.004).
Patients were divided into 2 age sub-groups: 6-24 and 26-60 months. A significantly higher number
of cases in FC compared with non-FC group were in age subgroup of 6-24 months (P=0.028).
Conclusion: Our study revealed a prevalence rate of 3.18% and an incidence rate of 5% for FC among
children with urinary tract infection. Also FC subjects had a significantly younger age at presentation
than non-FC cases. We found that FC as presentation of urinary tract infection occurred up to 3
years old, and there is no significant gender difference between FC and non-FC cases
