Introduction
![Page 3: Correlation study between steroid responsive nephrotic syndrome with clinical allergies in children at tertiary care centre in Odisha](https://reader034.vdocuments.mx/reader034/viewer/2022042801/58752f481a28abe7728b544b/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://reader034.vdocuments.mx/reader034/viewer/2022042801/58752f481a28abe7728b544b/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://reader034.vdocuments.mx/reader034/viewer/2022042801/58752f481a28abe7728b544b/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://reader034.vdocuments.mx/reader034/viewer/2022042801/58752f481a28abe7728b544b/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.
