Introduction
Nephrotic syndrome is a common renal pediatric
disorder reported in 20 – 40 million population
worldwide, with incidence in Indian subcontinent being
90-100 per million.
It is characterized by generalized edema, heavy
proteinuria, hypo-albuminemia, and hyperlipidemia.
95% cases of nephrotic syndrome are idiopathic with
80% cases having minimal change histology
synonymous with steroid responsive nephrotic
syndrome.
Study of relationship between Nephrotic syndrome
especially steroid responsive type and clinical allergies
in children.
Objectives1. Relate concurrence of steroid responsive nephrotic
syndrome and clinical allergies.
2. Relate Serum IgE levels in steroid responsive
nephrotic syndrome and clinical allergies.
3. Relate familial occurrence of allergy in cases of
nephrotic syndrome.
Materials and Methods.
Type of Study:- Cross-sectional study
Place of study :- Dept. of Pediatrics, SCB Medical college
and SVPPGIP, Cuttack, Odisha.
Duration of Study:- 2 years.
(Sept. 2013 to Aug. 2015 )
Appropriate consent from all participants and Ethics committee approval taken before starting study.
Three groups were studied with sample size and description as follows.
Group A- Cases (Nephrotic Syndrome).(n=80)
Group B (Control) - Children primarily presenting for non atopic conditions but who may be having history of or existing clinical allergy.(n=70)
Group C (Control) - Healthy Children. (n=40)
INCLUSION CRITERIA:
Children 2-10 years of age.
Children having clinical and biochemical evidence of Nephrotic syndrome.
EXCLUSION CRITERIA:
Children < 1year.
Children with nephrotic syndrome with associated features of azotemia, hematuria, hypertension.
Children with immunodeficiency disorders.
Children with edema due chronic liver disease, CCF, severe malnutrition etc.

RecommendationsIn spite of best efforts taken for the study, the following
improvements are suggested during further research.
Study should be conducted at a grass root level.
Larger studies could further validate results.
Appropriate follow-up done.
Relation to steroid intake studied.
Conclusion
In the present study of the 80 cases presenting with
nephrotic syndrome, the incidence of four main allergies
in control groups B and C (19%, 13%) were significantly
lower.
64% cases (p<0.05; Significant) of nephrotic
syndrome presented with clinical allergies.
Here, nephrotic syndrome was found to have a greater
incidence of association with these allergies:-
Allergic rhinitis (58%), Allergic dermatitis (12%),
Asthma (9%) and food allergy (2%).
Allergic manifestation, related to relapse in none it was a
consistent or concurrent happening.
In this study we found a strong significant association
between Nephrotic syndrome and clinical allergies.
It was further supported by elevated levels of Serum IgE
in our cases of Nephrotic syndrome.
95% cases had serum IgE >300IU/ ml.
64% cases had a mean level of >1550 IU/ml. These were
the cases presenting with clinical allergies.
Finally, there was a significant familial history of allergy in cases of nephrotic syndrome.
