The development of an arteriovenous fistula (AVF) after renal graft biopsy is a rare complication, it is associated in most cases with spontaneous resolution. However, interventional therapies are required in some cases, to prevent graft loss. Selective embolization has been described as an alternative treatment. In the present study, we describes our experience on AVF after biopsy in kidney transplant patients, which was managed with selective embolization. From 2005 to 2015, a total of 452 kidney transplant biopsies were performed, 12 had an AVF requiring embolization. In 92% of cases, this was successful. Beforehand, mean serum creatinine levels were 2.45 mg/dL, after the procedure, that increased to 3.05, however, 3 months later, mean creatinine levels dropped to 1.85 mg/dL. Graft survival after 2 follow-up years was 72%. Our experience demonstrates that selective embolization of the AVF after kidney transplant biopsy is a safe procedure, and that transplant function can be maintained in patients with this complication.A 30-year-old woman with history of passage of stones since childhood presented with oliguria and pedal edema for 10 days. She had hypertension with a creatinine of 4.1 mg/dL. Evaluation showed presence of bilateral multiple renal calculi with features of chronicity of kidney disease. Metabolic work-up for nephrolithiasis turned out to be negative and eventually renal biopsy revealed features of chronic interstitial nephritis with greenish brown refractile crystals in the tubular lumen and interstitium. The possibility of dihydroxy adenine crystalline nephropathy was considered. Spectrophotometry of RBC lysates revealed decreased activity of Adenine phosphoribosyl-transferase enzyme. Gene amplification by PCR and sequential analysis identified a missense mutation in exon 3 region of APRT gene in the patient and her family members. This case report highlights the need to contemplate the diagnosis of DHA crystalline nephropathy in young patients with nephrolithiasis and the identification of a rare genetic mutation, which is being reported for the first time in India.Encapsulating peritoneal sclerosis (EPS) is an infrequent but serious complication of long-term peritoneal dialysis (PD). EPS may become clinically apparent when patients are on PD (classical EPS) or after undergoing kidney transplantation (post-transplantation EPS). This presentation of EPS seems to occur shortly after kidney transplantation in former PD patients. In this report, we present our experience in our first case of patient diagnosed with EPS after kidney transplantation.Rosuvastatin is a recently approved statin and used widely across the globe for primary and secondary prevention of atherosclerotic cardiovascular heart disease. It has the highest lipid-lowering property among all statins and relatively well tolerated. Rhabdomyolysis is a rare but potentially serious adverse effect. The present report highlights the case of a patient admitted with proximal myopathy with severe rhabdomyolysis and acute kidney injury associated with life-threatening hyperkalemia. The symptoms appeared within 1 month of starting rosuvastatin. He required temporary dialysis to overcome the crisis. His myopathy and kidney injury were completely reversible after a few months of stopping the drug. In this report, we have also discussed the various risk factors for developing myopathy with statins and the importance of strict pharmacovigilance, and a greater caution among physicians while using this drug.Thromboembolism remains a common complication of nephrotic syndrome (NS) in adults and a less common complication in children. Venous thrombosis is well recognized, but arterial thrombosis occurs less frequently and is seen primarily in children. We report a case of arterial thrombosis associated with factor V Leiden (FVL) mutation in a young girl with NS. Screening for inherited thrombophilias such as FVL mutation may be beneficial for NS patients with thromboembolic vascular events not explained by conventional risk factors.Atypical haemolytic uremic syndrome (aHUS) is a clinically and genetically heterogeneous condition caused by a complex interplay between genomic susceptibility factors and environmental influences. Pathogenic variants in the DGKE gene are recently identified in cases with infantile-onset autosomal recessive aHUS. The presence of low serum C3 levels, however, has rarely been described in cases of DGKE-associated aHUS. Molecular genetic testing was performed by a commercial next-generation sequencing (NGS) panel as well and by an in-house developed targeted NGS for DGKE gene. Copy number variations (CNVs) were computed from NGS data by calculating a normalised copy number ratio of aligned number of reads at targeted genomic regions against multiple reference regions of the same sample and multiple controls. We report here two such novel clinically relevant variants (c.727_730delTTGT and c.251_259delGCGCCTTC) in the DGKE gene, in two families of infantile aHUS with low serum C3 levels.Childhood nephrotic syndrome is associated with significant morbidity because of recurrent relapses, infections, and episodes of thromboembolism. Thromboembolism in nephrotic syndrome may involve any major blood vessel. Timely recognition of symptoms and early initiation of anticoagulation therapy are important to avoid end-organ damage. We present here a case of a child with steroid-resistant nephrotic syndrome (SRNS) with bilateral central retinal artery occlusion (CRAO), whose vision improved with anticoagulation therapy.Plasmablastic lymphoma (PBL) is an aggressive lymphoma commonly associated with HIV infection. It most commonly presents in the oral cavity and rarely involves the kidney. Herein, we report a case of HIV positive male with renal involvement of PBL. The patient presented with unilateral severe hydronephrosis with unaltered renal functions. Despite aggressive management, there was an early relapse and the patient died within 2 years of the diagnosis. Despite the recent advances in the therapy of HIV-associated aggressive lymphomas, patients with PBL have a poor prognosis. Multimodal treatment with chemotherapy, newer targeted and biological agents, along with hematopoietic stem cell transplantation is essential for the treatment of PBL.Rhabdomyolysis is a syndrome with a wide range of symptoms ranging from asymptomatic raised serum creatinine kinase to life-threatening metabolic disturbances and acute kidney injury. TGF-beta inhibitor A careful history taking and high clinical suspicion on drug-drug interaction are crucial to identify the etiology of rhabdomyolysis. Here, we present a case of rhabdomyolysis due to a rare drug-to-drug interaction of simvastatin, diltiazem, and cyclosporin in a patient with IgA nephropathy. Early renal replacement therapy was initiated, and the insulting agents were withheld. Despite the metabolic disturbances were corrected, the patient succumbed to possible venous thromboembolism event during the prolonged hospital stay. Therefore, heightened awareness is required in dealing with patients with glomerulonephritis who are frequently prescribed on polypharmacy, in order to reduce unwarranted adverse events.Kidney paired donation is the most cost-effective approach in incompatible donor-recipient pairs. Incompatibility may be due to blood group, human leucocyte antigen crossmatch or both. In many cases of a living donor kidney transplant, there is only one potential donor who becomes unsuitable due to any of the above mentioned factors. In kidney paired donation, donor-recipient pairs are exchanged to sort out the incompatibility. We report our first successful three-way kidney exchange transplantation from North India. As deceased donor program is still in evolving stage in most parts of our country and transplant with desensitization protocol is associated with financial constraints, infections, and lack of availability in many centers, kidney paired donation is a valuable approach to expand the donor pool.
Lupus nephritis (LN) is a common complication of systemic lupus erythematosus. Vitamin D and cycline-dependent kinase-1 (CDK1) have been implicated in its pathogenesis. The aim of this study was to determine the relation between vitamin D level and CDK-1 in lupus nephritis patients and their impact on disease activity.

The current study was conducted on 50 LN patients and 20 control subjects from Egyptian population using ELISA to assess vitamin D level in serum and TaqMan assay for CDK1 gene expression.

Serum vitamin D level was significantly lower in LN patients and
gene was down expressed in the majority of LN patients. A significant inverse correlation was found between vitamin D level and 24 h protein in urine, ANA, anti-dsDNA, CRP, with a significant positive correlation with renal biopsy indices, eGFR. There was a non-significant inverse correlation between vitamin D and
(before RO-3306 addition) and a positive correlation after RO-3306. A significant positive correlation was found between
gene expressions with urinary albumin/creatinine ratio. However, a significant positive correlation was found between
(after RO-3306 addition) and proteinuria. While a significant positive correlation was found between
expression (after RO-3306 addition) and ANA, a significant positive correlation was found between
expression (before RO-3306 addition) and anti-dsDNA but CDK-1 is not associated with renal biopsy indices nor with activity indices of SLE. There was a positive correlation between
gene expression and CRP before and after RO-3306 addition.

Vitamin D deficiency acts as a risk factor for developing LN.
may have an association with the diagnosis of LN but its association with the progression of staging of LN is still confusing.

Crescentic glomerulonephritis (CrGN) characterized by the presence of crescents in most (≥50%) glomeruli on renal histology clinically presents as rapidly progressive renal failure. It can occur due to diverse etiologies with varying course and renal outcomes. We studied the prognostic significance of its classification as pauci-immune, anti-GBM, and immune-complex mediated CrGN.

Renal biopsies diagnosed as CrGN over 9 years were included. Clinical, biochemical, serological, and histological features of various classes of CrGN were correlated with renal outcome.

215 biopsies were diagnosed as CrGN during this period. A majority (63%) were immune-complex mediated while 32% were pauci-immune, followed by anti-GBM disease (5%). 85.5% of pauci-immune CrGN were ANCA associated. The levels of proteinuria and serum creatinine were significantly higher in anti-GBM CrGN as compared to the other two classes. The various histological features including Bowman's capsule rupture, peri-glomerular granulomatous reaction, fibrinoid necrosis, and vasculitis were more common in anti-GBM disease and pauci-immune CrGN. The median renal survival was 6.3, 5.3, 2.1 months in immune-complex mediated, pauci-immune, and anti-GBM CrGN, respectively.

Immune-complex mediated is the commonest etiology of CrGN in India. Anti-GBM disease has the worst prognosis followed by pauci-immune and immune-complex mediated CrGN. Raised serum creatinine levels (>5mg%) and the degree of glomerulosclerosis at diagnosis were predictors of poor renal survival. High index of suspicion and prompt diagnosis can improve the outcome in these patients.
