Detailed Description
NS is the most frequent glomerular disease in children. Between 80% and 90% of children with steroid-sensitive nephrotic syndrome (SSNS) will relapse following an initial response to corticosteroids. Half of these children will experience frequent relapses (FRNS) or become steroid-dependent (SDNS).
Infection is the most common and serious complication in children with NS. More than 80% patients had infections before relapse. The results of multiple observational studies and randomized control trials have shown that Broncho-Vaxom, a lysate of 8 common bacterial respiratory pathogens, is safe and effective to prevent infections in children. To the investigators' knowledge, Broncho-Vaxom has never been investigated for the initial episode of NS with the aim to reduce the subsequent risk of relapse that is a major concern in the management of children with NS.
Children aged 1-18 years with the first episode of the SSNS will be treated with Broncho-Vaxom for 6 months. The prednisolone at a dose of 2 mg/kg per day (maximum 60 mg in single or divided doses) for 6 weeks, followed by 1.5 mg/kg (maximum 40 mg) as a single morning dose on alternate days for the next 6 weeks; therapy is then discontinued.

The proportion of patients with relapse
|
6 months period after administration of Broncho-Vaxom therapy
|
The effect of Broncho-Vaxom on peripheral blood B cell subsets and T cell subsets to highlight biomarkers useful for monitoring response to Broncho-Vaxom treatment.
Time Frame: 1-year period after administration of Broncho-Vaxom therapy
|
Using fluorescence-activated cell sorting (FACS), peripheral blood B cell subsets and T cell subsets will be measured as at baseline, before and after infusion of Broncho-Vaxom at 3,6,9,12 months, and when relapse.
|
1-year period after administration of Broncho-Vaxom therapy
|
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0
Time Frame: 1-year period after administration of Broncho-Vaxom therapy
|
It is a binary variable (1/0).
The varibale would be setted as "1" if any adverse events occours including cough, diarrhea, abdominal pain, skin rashes, hives, swelling, eyelid/facial swelling, nausea, vomiting, systemic skin rashes, itching, fatigue, peripheral swelling, angioedema, etc. Adverse events will be graded according to the Common Terminology Criteria for Adverse Events.
