3. 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.
4. 95% cases of nephrotic syndrome are idiopathic with
80% cases having minimal change histology
synonymous with steroid responsive nephrotic
syndrome.

20. Recommendations
In 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.
22. 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.
23. 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.
24. 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.
25. Finally, there was a significant familial history of allergy
in cases of nephrotic syndrome.

Editor's Notes
Characters in numbering
In 1951, Fanconi et al. were among of the first to associate atopy and nephrotic syndrome.
In 1974, Shalhoub postulated that nephrotic syndrome might be secondary to a disorder of T lymphocyte function.
More recent studies have implicated IL-13 as a potential mediator of MCD. Podocytes express IL-13 receptors and, in response to IL-13 binding, CD80 a transmembrane protein has a key role in T-cell costimulation.
Intracellular expression of IL-13 by T cells correlated directly with serum IgE level.
Reiser and Mundel have suggested that CD80 expression could be a mechanism for MCD
Kimata et al. were the first to report that although spontaneous IL-4 production by T cells was increased in patients with atopy, IL-13 production by T cells
was increased in patients with MCD.
Persons with atopy have a hereditary predisposition to produce IgE antibodies to common allergens and often manifest with 1 or more atopic diseases
Type 2 helper T cells (Th2) from patients with atopy respond to allergens in vitro expressing such cytokines as interleukin 4 (IL-4) and IL-13
IgE synthesis by B cells requires 2 signals. The first signal is delivered by the cytokines IL-4 or IL-13 released by Th2 cells. The second signal is delivered by interaction of the B-cell surface antigen CD40 with its ligand expressed on activated T cells.
Therefore, patients with atopy typically present with increased serum IgE and serum IL-4 and IL-13 levels, although on repeated exposure to same allergen, patients also may have increased plasma levels of interferon.
Statistical Analysis
Statistical Methods: Descriptive and inferential statistical analysis has been
carried out in the present study. Results on continuous measurements are
presented on Mean ± SD (Min-Max) and results on categorical measurements
are presented in Number (%).
Significance is assessed at 5% level of
significance. The following assumptions on data is made:
Assumptions: 1.Dependent variables should be normally distributed,
2.Samples drawn from the population should be random. Cases of the
samples should be independent.
Chi-square test has been used to find the significance of study parameters
on categorical scale between two or more groups.
Significant figures
+ Suggestive significance (p value: 0.05<p<0.10)
* Moderately significant (P value: 0.01<p£ 0.05)
** Strongly significant (p value: p£0.01)
Statistical software: The Statistical software namely SAS 9.2, SPSS 21.0,
Stata 10.1, MedCalc 9.0.1, Systat 12.0 and R environment ver.2.11.1 were
used for the analysis of the data and Microsoft Word and Excel have been
used to generate graphs, tables etc.
