Abstract PDF: Background
Minimal change nephritic syndrome (MCNS) is characterized by a lack of obvious abnormalities on light microscopy, but its electron microscopic findings include the negative immunofluorescence findings and the diffuse effacement of the epithelial cell foot processes. Rarely the presence of electron dense deposits (EDDs) has been reported, but its clinical significance remains obscure.
Methods
Eleven patients with MCNS who had the EDD deposited were enrolled in the current study. We compared the clinical characteristics, laboratory results and response to steroid treatment between the two group: the EDD group (n=11; the male-to-female ratio, 8:3) and the non-EDD group (n=13, 8:5).
Results
There were no significant differences in most of the laboratory results or response to steroid treatment between the two groups. The frequency of relapses per year was significantly higher in the EDD group (1.1±0.7 times vs. 0.5±0.6 times; p=0.023). These EDDs were found in the mesangium or paramesangium. With no respect to the characteristics of EDDs, our results showed that they did not cause poor treatment outcomes except for the annual frequency of relapse.
Conclusions
Further large-scale studies are warrented to determine the immunologic and prognostic significance of EDDs in patients with MCNS.

Abstract PDF: PURPOSE: There is no specific treatment guidelines for Henoch-Schonlein (HS) nephritis. Therefore we performed this study to observe the effect of long term steroid therapy combined with azathioprine METHODS: Treatment protocols; 1) Steroid pulse therapy: methylprednisolon 30 mg/kg/dose, maximum 1 gm, intravenously 6 times for alternate day. 2) Oral steroid was given 2 mg/kg/day for 1 month, 1 mg/kg/day for following I month and alternate day oral steroid combined with azathioprine 2 mg/kg/day for 2 years. RESULTS: Time period from HSP to onset of HS nephritis was between 2 weeks to 5 months with mean 7.4+/-7.4 weeks. Clinical remission were seen in 4 cases out of 5 (80%). Mean time period with disappearance of proteinuria and microscopic hematuria were 5+/-2.4 month and 13.3+/-2.9 month respectively. On pathologic findings by ISKDC, 3 cases were grade IIIb, 2 cases were grade IV in first kidney biopsies and showed pathologic improvement in follow up kidney biopsies after 2 years treatment. CONCLUSION: As there no definitive treatment for HS nephritis so far, our study of long term oral steroid therapy with azathioprine was effective in clinical and histologic aspect. Therefore further study in HS nephritis with in a large group will be needed in the future.

Case Report

Lymphadenopathy of Kimura's disease Associated with Nephrotic Syndrome: A case report.: Bohong Hee Kim, Myung Suk Kang, Young Hee Maeng, Young Koo Park, Juhie Lee, Moon Ho Yang; Korean J Pathol. 1995;29(1):113-115.

Abstract PDF: Kimura's disease is an important category of reactive lymphadenopathy especially among Asians. It is a chronic inflammatory disorder of unknown etiology and is characterized by angiolymphoid proliferation and eosinophilia. The patient was a 17-year-old man with a 3-year-history of submandibular lymphadenopathy Who was referred to Kyung Hee University Hospital for evaluation of enlarging mass. He had a history of nephrotic syndrome for 7-8 years since 1984. Laboratory findings were not specific except for peripheral blood eosinophilia. The submandibular lymph node showed florid germinal enters, increased postcapillary venules in the paracortex, eosinophilic infiltration, and sclerosis. In this paper, a case of lymphadenopathy of Kimura's disease associated with nephrotic syndrome is reported.
