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.

Aim

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.
