IgA nephropathy is the most common form of primary glomerulonephritis and chronic glomerular disease worldwide including Korea. Familial gathering of IgA nephropathy suggests that genetic factors contribute to the development of this disease. Although there have been many reports on familial IgA nephropathy with genetic analysis and their pedigrees, there has been few reports in Korea. We reported a partial familial IgA nephropathy pedigree with a brief review of the literatures.

According to The Comparative study on the IgA Nephropathy and hematuria, the results were as follows. 1. IgA nephropathy is included in category of the hematuria the part in deficiency of liver-kidney and damp-heat in oriental medicine. 2. The symptoms of hematuia is changes in color of urine-bloody, dark brown, or rusty colored-without pain in oriental medicine. 3. It is occured IgA nephropathy due to vacuity exhaustion, fidgetiness, internal damage, imfection. 4. For the medical prescriptions due to IgA nephropathy are used Sogyeeumja, $Dayebunch\check{o}ngeum$(大分淸飮), Dangguieum(當歸飮), $Ch\check{o}ngjangtang$(淸腸湯), Silyungtang(柴岺湯), Kamisagunjatang(加味四君子湯) as hematuria of symtom of IgA nephropathy.

Objectives The purpose of this study is to review relevant clinical studies to investigate the effectiveness of herbal medicines for IgA (Immunoglobulin A) nephropathy in children. Methods Studies on herbal treatment for IgA nephropathy were searched and analyzed through electronic databases such as PubMed, EMBASE, China National Knowledge Infrastructure, Wanfang, CiNii, J-STAGE, Oriental Medicine Advanced Searching Integrated System and Science ON. Studies included Randomized controlled trials and case series. Results We selected nine studies and analyzed the findings. In most studies, improvement of IgA nephropathy was observed after treatment, and was evaluated using factors as 24 hour urine protein, hematuria, Scr (serum creatinine) and BUN (blood urea nitrogen). The most commonly used herbs for IgA nephropathy were Poria cocos (茯苓), Astragalus membranaceus (黃芪), and Rehmannia glutinosa (生地黃). Conclusions Based on the results of the clinical studies, we identified that herbal medicine is an effective treatment for IgA nephropathy. However, additional systematic clinical studies are necessary to prove its effect and safety.

IgA nephropathy usually presents as asymptomatic microscopic hematuria or proteinuria or episodic gross hematuria after upper respiratory infection. It is an uncommon cause of end-stage renal failure in childhood. Pulmonary hemorrhage associated with IgA nephropathy is an unusual life-threatening manifestation in pediatric patients and is usually treated with aggressive immunosuppression. Pulmonary hemorrhage and renal failure usually occur concurrently, and the pulmonary manifestation is believed to be caused by the same immune process. We present the case of a 14-year-old patient with IgA nephropathy who had already progressed to end-stage renal failure in spite of immunosuppression and presented with pulmonary hemorrhage during oral prednisone treatment. His lung disease was comparable to diffuse alveolar hemorrhage and was successfully treated with plasmapheresis followed by oral prednisone. This case suggests that pulmonary hemorrhage may develop independently of renal manifestation, and that plasmapheresis should be considered as adjunctive therapy to immunosuppressive medication for treating IgA nephropathy with pulmonary hemorrhage.

The pathogenesis of IgA nephropathy and acute poststreptococcal glomerulonephritis is not fully understood. In the past, acute poststreptococcal glumerulonephritis was the most common cause of gross hematuria in children, but now IgA nephropathy is the most common one. We experienced two cases of acute poststreptococcal glomerulonephritis superimposing to IgA nephropathy in boys Case 1 had upper respiratory infection before elevation of anti-streptolysin O, generalized edema, gross hematuria and proteinuria. The complement levels were normal. Electron microscopic findings of renal biopsy at ten days after onset showed a few big subepithelial 'humps' and localized heavy subendothelial and mesangial deposits. Immunofluoroscopic findings revealed predominant IgA deposition in the mesangium. The electron microscopic findings were diagnostic of acute poststreptococcal glomerulonephritis On the other hand, immunoflorescence microscopic findings were compatible to IgA nephropathy. In case 2, the renal biopsy which was done 2 years after onset showed only finding of IgA nephropathy. To our knowledges, there has been kw reports of acute poststreptococcal glomerulonephritis superimposing to IgA nephropathy which was confirmed by renal biopsy. We report two cases of acute poststreptococcal glomerulonephritis superimposing: to IgA nephropathy with a brief review of the literatures.

There are a considerable number of reports suggesting a common pathogenesis of IgA nephritis(IgANn) Henoch-$Sch{\ddot{o}}nlein$ Purpura(HSP). In previous reports, a patient develops IgAN after kidney transplantation for HSP nephritis, one of Identical twin boys, developed IgAN and the other HSP, and a boy with IgAN later developed HSP. We report two cases, one with IgAN who later developed HSP and the other with HSP who later developed IgAN, suggesting that IgAN and HSP have a common pathogenesis. (J.

It has been suspected that various infections, including cytomegalovirus(CMV) infection, are associated with IgA nephropathy. In case of CMV infection, ganciclovir is known to be a treatment of choice for severe CMV infection in general. But ganciclovir has a lot of severe toxicity, so children with normal immunity are seldom treated by ganciclovir when CMV infection is suspected. On the other hand, intravenous immunoglobulin can also be used to treat CMV infection. We report a case of CMV-associated IgA nephrophaty, who was treated with deflazacort and Intravenous immunoglobulin therapy. An 11 years old boy suffered from gross hematuria for 3 days. He had proteinuria, thrombocytopenia(104,000/$mm^3$), antiplatelet antibody(＋), impaired renal function and low serum albumin. His CMV serology was CMV-IgM/IgG(＋/-) and urine CMV-PCR was positive. The renal histological findings revealed IgA nephropathy, WHO class II. His proteinuria persisted despite of deflazacort therapy(2.5 mg/kg/day). Later, intravenous immunoglobulin(1 g/kg) was administered twice. In two years, he showed no gross and microscopic hematuria, and his laboratory findings were also normalized.

This case is to report the effect of renal function of chronic kidney disease(CKD) caused by IgA nephropathy. A 37-year-old man visited a Korean medicine hospital, who has been diagnosed with end stage renal disease(ESRD), 5 stage of CKD, caused by IgA nephropathy, has had no improvement of western medical treatment, and wanted to be treated using Korean medicine before renal transplantation. The decrease of creatinine value, the increase of glomerular filtration rate(GFR), and the decrease of CKD stage (5 to 4) was observed after combination treatment of Ikkigeonbiisuhwalhyeoltang and saam acupuncture was applied. This case report is suggested that combination treatment of acupuncture and herbal medicine could be effective to renal function of CKD in spite of a single case.

Purpose : The intestinal mucosal defect has been known as one of the pathogenicmechanisms of IgA nephropathy. Oral antigens usually induce the activation of Th2 cells and mast cells. These cells secrete cytokines IL-4, IL-5 and TGF-$\beta$, which increase IgA production. Although ketotifen (benzocycloheptathiophene) is an H1 antagonist and a mast cell membrane stabilizer, it could protect the gastrointestinal membrane through inhibiting the production of IL-4, IL-5, PGE2, and LTB4, and decreasing the activity of nitric oxide synthease. Therefore, we have investigated if ketotifen may protect the development of IgA nephropathy with an oral antigen. Methods : ICR mice were used as an animal model orally with Poliovax only [ketotifen (-)], the other group was given oral ketotifen [ketotifen (+)] in addition to Poliovax. Results : Mesangial IgA deposition developed in 11 out of the 18 mice in the ketotifen (-) group, while in three out of the nine mice in ketotifen (+) group. The mesangial change developed in 16 out of the 18 mice in the ketotifen (-) group, while in five out of the nine mice in the ketotifen (+) group. Serum IL-4 and IL-5 levels were not significantly lower in the latter group than in the former. Conclusion : According to the statistical results from the above, ketotifen therapy would be beneficial to reducing mesangial changes in IgA nephropathy.
