Introduction
![Page 3: Correlation study between steroid responsive nephrotic syndrome with clinical allergies in children at tertiary care centre in Odisha](https://reader031.vdocument.in/reader031/viewer/2022011721/587530581a28abe7728b55e3/html5/thumbnails/3.jpg)
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.

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
![Page 22: Correlation study between steroid responsive nephrotic syndrome with clinical allergies in children at tertiary care centre in Odisha](https://reader031.vdocument.in/reader031/viewer/2022011721/587530581a28abe7728b55e3/html5/thumbnails/22.jpg)
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.
![Page 23: Correlation study between steroid responsive nephrotic syndrome with clinical allergies in children at tertiary care centre in Odisha](https://reader031.vdocument.in/reader031/viewer/2022011721/587530581a28abe7728b55e3/html5/thumbnails/23.jpg)
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.
![Page 24: Correlation study between steroid responsive nephrotic syndrome with clinical allergies in children at tertiary care centre in Odisha](https://reader031.vdocument.in/reader031/viewer/2022011721/587530581a28abe7728b55e3/html5/thumbnails/24.jpg)
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.
