作者： gaurav vohra Army Command Hospital Chandimandir India

Background: In subjects on CAPD who use icodextrin for long night dwell, it has been recommended that nocturnal exchange be replaced by dextrose dwell whenever PET is to be performed as preceding exchange with icodextrin temporarily increases peritoneal membrane permeability and therefore, gives high D/PCr and low D/D0 glucose values. Whether this temporary change is also seen with use of Uni-PET (which involves one hour dwell of 1.5% dextrose followed by 4-hour dwell of 4.25% dextrose) is not known. Methods: In this self, controlled study, subjects on CAPD, who were using icodextrin for long nocturnal dwell for at least 3 months, were screened for enrolment. Pregnancy or lactation, history of any PD related infectious complication in the past one month, present or past malignancy, and poor functional status were exclusion criteria. Enrolled subjects underwent classic PET with preceding 2.5% dextrose long nocturnal dwell on day 1 followed by Uni-PET with preceding 7.5% icodextrin long nocturnal dwell on day 2. Difference in D/PCr and D/D0 glucose between the two PETs was primary objectives. The study was approved by Institute Ethics Committee. Results: 15 out of 26 screened subjects were enrolled over a period of 18 months (July 2015-December 2016). The mean (±SD) age of study population was 60.8±9.1 years. Majority were males and diabetes was the most common cause of CKD. Mean D/PCr were 0.68 ± 0.11 and 0.64 ± 0.08 in classic PET and Uni-PET, respectively. The difference between the two values was not significant [mean difference between D/PCr (classic PET-Uni-PET): 0.040 ± 0.86;95% CI (-0.007 to 0.088);p = 0.09]. Similarly, D/D0 glucose between classic PET and Uni-PET was also similar [mean difference between D/D0 glucose (classic PET-Uni-PET): -0.02 ± 0.09;95% CI (-0.06 to 0.03);p = 0.448]. Conclusion: Peritoneal membrane small solute transport characteristics in Uni-PET wit

Spectrum of Primary Glomerular Diseases in Patients Presenting with Urinary Abnormalities

引用

Open Journal of Nephrology 2022年第4期12卷 451-459页

作者： gaurav vohra Kumar Anand Shrutiraaj Himani Dalal Gurjeet Singh Chowdhary Army Command Hospital Chandimandir India Medicine Army Hospital YOL India

Introduction: Primary Glomerular Diseases are a spectrum of renal disorders of unknown aetiology with distinct characteristics, specific natural history and prognosis. A thorough evaluation is prerequisite to establish the diagnosis since many systemic diseases and secondary aetiology masquerade as primary diseases. Methods: This prospective observational study was conducted at a tertiary care centre and included 30 patients, with clinical features suggestive of primary glomerular diseases, of which 23 patients (76.6%) were males and 07 patients (23.33%) were females. The mean age at presentation was 37.23 ± 12.89 years. Among the observed spectrum of Primary Glomerular Diseases, IgA Nephropathy (IgA N) was seen in 26.67% patients, Focal Segmental Glomerulosclerosis (FSGS) in 20% patients and Membranous Glomerulopathy (MGN) in 13.33% patients, whereas the incidence of other abnormalities had less percentage contribution. Proteinuria was the commonest presentation seen in 60% patients, followed by Microscopic Haematuria in 20%. Mean Serum Creatinine was 0.99 ± 0.16 mg/dl. Mean Serum Albumin was 2.51 ± 0.76 gm/dl. Overall Nephrotic range proteinuria was observed in 15 (50%) patients. Results: IgA N, FSGS & MGN were the commonest observed Primary Glomerular Diseases. Proteinuria, Haematuria, Anasarca and Pedal Oedema were the commonest observed clinical presentations. Conclusions: In this studied series IgA Nephropathy, FSGS and MGN were the most prevelant diagnoses in the patients presenting with Urinary Abnormality. Nephrotic range Protenuria was the major indication for biopsy, there is a temporal variation in glomerulopathies wherein there is increase in incidence of IgA Nephropathy and decrease in incidence of FSGS.
