BACKGROUND Percutaneous renal biopsy (PRB) can result in serious complications. The study is aimed to compare the biopsy yield and complications rate of the real-time ultrasonagram (USG)-guided PRB and needle tracking with and without needle guide in two different study periods. METHODS We compared the yield and complications of 2138 kidney biopsies(More)
BACKGROUND Granulomatous tubulointerstitial nephritis (GIN) is common due to infections, drugs or sarcoidosis. However, the cause is often difficult to establish and the studies are limited. We studied the etiology of GIN and compared the clinical and histological features and outcome in different etiologies at a tertiary care center in North India. (More)
BACKGROUND We aimed to longitudinally analyse changes in the levels of serum fibroblast growth factor 23 (FGF23), intact parathyroid hormone (iPTH) and associated minerals in patients undergoing renal transplantation. METHODS Sixty-three patients with end-stage renal disease (ESRD) who underwent living donor transplantation were recruited. Serum FGF23,(More)
Chronic kidney diseases (CKD) adversely affects fetal and maternal outcomes during pregnancy. We retrospectively reviewed the renal, maternal and fetal outcomes of 51 pregnancies in women with CKD between July 2009 and January 2012. Of the 51 subjects (mean age 27.8 ± 7.04), 32 had 19 had estimated glomerular filtration rate (eGFR) <60 ml/min. There was(More)
Carbon nanotubes (CNT) were synthesized on nanopatterned catalysts. The catalyst nanoparticles were obtained using dip pen nanolithographytechnique. Dip pen nanolithography technique was used to deposit NiCl(2) nanopatterns with sub-200 nm feature sizes on a silicon substrate. The deposited features were verified by using lateral force microscopy. The(More)
Pregnancy-associated acute kidney injury (PAKI) is encountered frequently in developing countries. We evaluated the maternal, fetal and renal outcomes in women with PAKI who needed at least one session of dialysis. Of the total of 98 cases (mean age 28.85 ± 5.13 years; mean parity 2.65 ± 1.28) of PAKI, the most common cause of PAKI was postabortal sepsis.(More)
Immunoglobulin A (IgA) dominant membranoproliferative glomerulonephritis (MPGN) is rare, described only as case reports. We report a rare case of an elderly man presenting with rapidly progressive renal failure and nephrotic range proteinuria with histological, immunofluorescence, and ultrastructural findings supporting a diagnosis of IgA dominant MPGN.(More)
Antiphospholipid syndrome (APS) often presents as a multisystem disorder characterized by recurrent arterial and venous thrombosis and pregnancy loss. We present a 46-year-old female who was admitted with oliguric acute renal failure. APS was suspected due to prolongation of activated partial thromboplastin time and history of miscarriages.
