Association of iron deficiency states and febrile seizures in children-a case control study

Background Iron deficiency being a potentially modifiable and treatable cause of febrile seizures.  Objectives of Study was to identify Iron Deficient States or Anemia in children with febrile seizures as evidenced by low hemoglobin, altered RBC indices and altered Iron profile, and to determine the association of Iron deficiency states or anemia with febrile seizures.

Methods This was a Case control study done between July 2013 to June 2014, on 50 indoor cases of febrile seizures in the age group of 6-60 months and 50 age and sex matched controls (fever without seizure) in department of Paediatrics, Hindu Hriday Samrat Balasaheb Thackrey Medical College (HBTMC) and Dr R.N. Cooper Hospital, Mumbai. Detailed clinical history and examination findings were noted.  Cases and control were investigated with complete blood count, RBC indices, peripheral smear, S. Ferritin, S. Iron and TIBC. SPSS software package was used for statistical analysis. P<0.05 was considered as significant.

Results 74% of cases and 66% of controls had low hemoglobin. MCV was low in 54% of cases and 34% of controls. RDW was raised in 46% of cases and 26% of controls. Iron deficiency anemia was prevalent among both cases and controls. Latent iron deficiency state suggested by low S. Iron and high TIBC in cases and control group was not significant in our study. However statistically significant lower Median S. Ferritin was noted in the febrile seizure group versus the controls (Cases-153.5, Control-173.0, p=0.0195) suggesting significant prevalence of prelatent iron deficiency state among cases.

Conclusions Prelatent iron deficient state in children are more prone for febrile seizures.
