Analysis of epidemiological characteristics and pathological types of 1 645 renal biopsy data / 临床与实验病理学杂志

Abtract:Purpose To analyze epidemiological characteristics and pathological types of 1 645 renal biopsies in Jiangsu province. Methods The reports of 1 654 percutaneous renal biopsies performed from January 2009 to June 2013 were retrospectively analysed . Results 1 597 out of 1 645 renal patients were successfully biopsied with a success rate of 97. 1%. Primary glomerular diseases ac-counted for 78. 56% of the total patients, secondary glomerular diseases 18. 71%. IgA nephropathy and mesangial proliferative lession accounted for high percent of primary glomerular diseases. Lupus nephritis was the most frequent pathologic type of secondary glomeru-lar diseases, followed by allergic purpura nephritis and diabetic nephropathy. Mesangial proliferative glomerulonephritis and hyperten-sive renal injury were more common in the Southern than in the Northern Jiangsu province, while acute tubular necrosis and allergic purpura nephritis were less in the Southern Jiangsu province. Conclusions Primary glomerular disease is still the most frequent glo-merular diseases in Jiangsu province, among which the IgA nephropathy was predominated. In secondary glomerular disease, lupus ne-phritis is the most frequent pathological type. The incidences of kidney diseases have geographical variation.

Patterns of Glomerulonephritis in Uttarakhand State 13 Years Single Centre Experience at Teaching Institute.

Aims : Glomerular disease is considered to be a common cause of chronic kidney disease and its prevalence and histological pattern differ according to geographical area, race, age in different regions of the world. The present study was therefore conducted to study the pattern of different histological types of glomerulonephritis in this area of Uttarakhand region of India over an extended period of 13 years. Material and Methods : Retrospective study was conducted in the tertiary care centre of Uttarakhand state which included cases of different types of glomerulonephritis diagnosed on histopathology over a period of 13 years. Age, sex, clinical presentation, relevant investigations and the histopathological type of glomerulonephritis were noted for every case. Results : Histopathological examination due to various non-neoplastic renal diseases was done in total 218 cases and out of these glomerular diseases was diagnosed in 178 cases. Proteinurea and edema was the most common presentation. Primary glomerulonephritis was observed in 88.5% cases and secondary in 9.9%. Mesangioprolifrative glomerulonephritis was the most common primary glomerulonephritis and nephropathy due to amyloidosis was the most common type of secondary glomerulonephritis. Conclusion : The study concludes that primary glomerulonephritis is the most common renal disease with mesangioproliferative glomerulonephritis as the most common primary glomerulonephritis and amyloidosis nephropathy as the most common secondary glomerulonephritis which differs from other regions of world. The study may be useful to pathologists, nephrologists and health care providers to formulate a basic platform for effective diagnostic, therapeutic and research base for glomerular diseases so as to prevent its complications.
