Chyluria is the presence of chyle in the urine and is associated with some degree of proteinuria. We report two patients with chyluria who presented with milky urine, weight loss, and edema and were found to have nephrotic-range proteinuria. Although filarial antigen was detected in only one of the patients, flexible cystoscopy could demonstrate chyle efflux from the left ureter in first patient and from both the ureters in the second patient. Both patients received endoscopic sclerotherapy with 0.2% povidone-iodine, which resulted in the clearance of milky urine in three to five days and complete resolution of nephrotic-range proteinuria on follow-up. They remained symptom-free until the six-month follow-up. We deferred renal biopsy in both patients, as proteinuria was confirmed to be non-glomerular in origin.

Background: Chronic kidney disease (CKD) is a global health problem, with a worldwide prevalence of around 9.1 per cent (as of 2017). In India, its prevalence was found to be around 17.2%. There are several risk factors of CKD, out of which the presence of underlying longstanding uncontrolled diabetes mellitus (DM) and hypertension are common. Certain previous studies have tried to assess the level of knowledge, attitudes and practices of such a ‘high risk’ group for developing CKD but there is a paucity of literature on it. Hence, this study was undertaken to assess these domains in individuals at risk for developing CKD. Patients and Methods: It is an observational cross-sectional study conducted from October 2020 to December 2021 at a tertiary care teaching and referral hospital in India. A total of 215 patients who were at risk of developing CKD, were enrolled and were given a CKD Screening Index questionnaire to fill and scoring was done for all three components-knowledge, attitudes and practices. Results: The mean age was found to be 49.21 ± 13.49 years with a male: female ratio of 1.4:1. Nearly three-a fourth of the patients were having DM while one-fourth of the participants had a previous history of hypertension. The mean scores on the knowledge, attitude and practices scales were found to be 11.80 ± 5.31, 50.18 ± 8.23 and 30.83 ± 7.53 respectively. The study results revealed that the majority of patients had ‘low’ levels of knowledge scores but ‘average’ levels of attitude and practice scores. A significant correlation was found amongst knowledge and attitude scores (r = 0.226, P = 0.001), knowledge and practice scores (r = 0.153, P = 0.025) and practice and attitude scores (r = 0.295, P = 0.000) of our patients. Conclusion: There is a need of improving awareness at least amongst the population at risk of getting CKD. Improving knowledge would help in inculcating positive attitudes and healthier practices amongst these, thus delaying the onset of this disease.

Aim: Pregnancy-associated hemolytic uremic syndrome (P-aHUS) is an important cause of peripartum acute kidney injury. Studies from Europe have described mutations in complement regulator genes, and data in Indian patients is scarce. Hence this study used multiplex ligation-dependent probe amplification (MLPA) to identify variants in complement genes in P-aHUS patients.Methods: We present 17 patients of P-aHUS who were investigated for complement protein levels and genetic analysis with MLPA for complement genes. Plasma exchange therapy was offered to all patients presenting in acute phase.Results: Mean age 26.74 (3.36) years with 15/17 delivered by caesarean section.Eleven patients received early (within 7 days) plasma exchange, three were dialysisdependent at 3 months and seven were dialysis-free. Only one of the three patients receiving late (after 7 days) plasma exchange was dialysis-free. MLPA showed that 11 patients had heterozygous deletions of exons 3, 5, 6 of CFHR1 and upstream region of exons 1, 2, 3, 6 and intron 4 of CFHR3 gene while four patients had homozygous deletions at the same loci. Two patients had no MLPA-detectable variations. Conclusion:This study reports a high proportion of deletions of exons of CFHR1 & CFHR3 genes in Indian P-aHUS patients detectable by MLPA by copy number variations. This needs confirmation in large multicentre studies. Plasma exchange can be an effective therapy in the non-availability of Eculizumab.
