Research Abstract |
Steroid sensitive idiopathic nephrotic syndrome (SSN) is the most common nephrotic syndrome in children. In most cases, SSN occurs sporadically and is considered to be a multifactorial disorder. However, familial clustering SSN was sometimes observed. To better define the contribution of genetic factors, we retrospectively studied clinical features and genetic influences in a cohort of 14 non consanguineous, unrelated SSN families of Japanese origin. The average age of onset was 4.3 years old. The interval of the onset between the affected sib-pair was 2.9 years old, which are quite similar to the features of European SSN families cohort. Despite the considerable intra-familial concordance with respect to the age of onset, therapeutic responsiveness and subsequent relapse frequency varied somehow between the affected sibs within a given family, even between affected monozygotic twins. Most patients experienced several, non-frequent relapses after initial treatment and enterd a complete sustained remission until age of 15 years. Eight patients had a more prolonged clinical course as they became frequent-relapsers and steroid-dependent. Renal biopsy showed minor glomerular abnormalities in 8 patients. A half of the patients (46%) had allergic diseases. All the 28 patients maintained a normal renal function during the observation period. Our results indicate that this cohort represents a familial form of SSN mimicking a common sporadic counterpart and will constitutes a subgroup of minimal change nephrotic syndrome where the recessive genetic factors plays a substantial role in the pathogenesis, possibly interacting with some epigenetic or environmental factors.
