RESUMEN
BACKGROUND: The population age is being high and nephotic syndrome is a common renal disease. OBJECTIVE: To find the etiology and clinical manifestations of nephrotic syndrome in the elderly patients who underwent renal biopsy at Siriraj hospital including management and outcome. MATERIAL AND METHOD: Retrospective study in 76 nephrotic patients whose age > or =50 years and underwent renal biopsy between 2005-2007. RESULTS: Seventy six nephrotic patients with age ranged from 50-84 years were analysed. Primary glomerulonephritis diseases were found more than secondary causes (5:2). The two most common glomerulonephritis were membranous GN and focal/segmental glomerulosclerosis. The etiology of common secondary GN was lupus nephtitis 11.84% following by diabetic nephropathy and amyloidosis. The patients received immunosuppressive drugs and complete response was found in 51%, partial response 10.2%, no response was 2% and no immunosuppressive therapy 36.7%. There was 1 patient died of septicaemia. CONCLUSION: Nephrotic syndrome in the elderly patients were not uncommon. The causes should be identified for prompt management and excellent outcome.

BACKGROUND: ANCA is detected in several vasculitic diseases, including drug-induced systemic vasculitis: propylthiouracil (PTU), hydralazine, minocycline, penicillamine, allopurinol, procainamide, carbimazole, thiamazole, clozapine and phenytoin. All have been known to induce ANCA positive vasculitis in adult patients. OBJECTIVE: To study the clinical manifestation, renal pathology and outcome of patients with ANCA positive vasculitis associated with propylthiouracil treatment in Siriraj Hospital. MATERIAL AND METHOD: Retrospective study in 7patients with Graves' disease who were treated with propylthiouracil and developed ANCA-positive glomerulonephritis between 2000-2008. RESULTS: Seven cases with Graves' disease who received propylthiouracil whose ages were 43 +/- 14 years. The duration of propylthiouracil treatment was 68.5 +/- 39 months and the doses were 50-150 mg per day. Six cases had P-ANCA and one case had C-ANCA in the serum. Proteinuria ranged from 0.49-2.9 gram per day. Mean serum creatinine was 2.05 mg/dl with creatinine clearance of 44 +/- 35 ml/min. The propylthiouracil was withdrawn in every patient and corticosteroid was administered. Renal remission was found until 1 year of follow-up. CONCLUSION: ANCA positive glomerulonephritis associated with propylthiouracil is not uncommon. The average onset of glomerulonephritis is 2 years or more. The propylthiouracil dosage was not necessary high. Urinalysis and other glomerulonephritis symptoms should be screened for early diagnosis and appropriate treatment in patients treated with PTU.

BACKGROUND: The knowledge of the epidemiology of biopsied renal diseases provides useful information in clinical practice. There are several epidemiologic population-based studies of biopsy-proven nephropathies with detailed clinicopathologic correlations that could be different according to the country analyzed. OBJECTIVE: To identify the prevalence of primary and secondary glomerular diseases and to study the trend of the pattern changes of the glomerulopathy in Thailand. MATERIAL AND METHOD: A retrospective study of percutaneous renal biopsies during a 23-year period of 1982 to 2005 was performed. A total of 3,555 consecutive native kidney biopsies in adult patients between 12 and 84 years of age were analyzed for the prevalence and changes in the 5-year interval over the two decades. RESULTS: From the clinical trial of 3,275 patients, the ratio between primary and secondary glomerular diseases was 2:1 (2154:1121). The most common primary glomerular disease (2154 patients) were IgM nephropathy (n = 986, 45.8%) followed by IgA nephropathy (n = 386, 17.9%); membranous nephropathy (n = 341, 15.8%); diffuse endocapillary proliferative glomerulonephritis (n = 114, 5.3%) and diffuse crescentic glomerulonephritis (n = 71, 3.3%). Lupus nephritis was the most prevalent cause of secondary glomerulonephritis in the present study (n = 992, 88.5%). Examination of the 5-year interval along the study period revealed a significant increase in the prevalence of IgA nephropathy and diabetic nephropathy. Prevalence of focal and segmental glomerulosclerosis rose by five times over the last two decades in contrast to IgM nephropathy, which prevalence is decreasing. CONCLUSION: There is high prevalence of IgM nephropathy, IgA nephropathy, and lupus nephritis in Thailand which is different from other countries. It could be due to various races and altered environments. The information obtained from these results is an important contribution for the understanding of the prevalence in renal diseases in Thailand. It can be used as the baseline data for making efficient research into the appropriate and beneficial way of management in the future.
