Article Synopsis
  • The COVID-19 virus primarily affects the respiratory system, but it can also lead to rare complications like rhabdomyolysis, particularly in cases with mild symptoms.
  • Serum creatine phosphokinase (CPK) testing is useful for diagnosing rhabdomyolysis in COVID-19 patients exhibiting musculoskeletal symptoms to prevent severe complications like acute kidney injury.
  • A young male with β-thalassemia minor tested positive for COVID-19 and, after showing symptoms like muscle pain and cola-colored urine, was diagnosed with rhabdomyolysis and successfully treated in the hospital.

Background: Medication nonadherence (MNA) in organ transplant recipients is associated with increased risk of rejection, allograft loss, patient death, and higher healthcare costs. Various approaches have been used in an attempt to reduce MNA. A patient support program (PSP) can be an invaluable tool for improving patient outcomes.

Membranous nephropathy (MN) is one of the most common causes of nephrotic syndrome (NS) in nondiabetic adults, with about 70%-80% of cases of MN being primary MN (pMN). Many studies have shown that serum phospholipase A2 receptor (PLA2R) antibodies are a diagnostic and prognostic biomarker for pMN, with a pooled diagnostic sensitivity and specificity of 54%-82% and 89%-100%, respectively, resulting in PLA2R staining and serum PLA2R antibodies being incorporated in the management algorithms of MN. We studied the sensitivity and specificity of serum PLA2R antibodies for diagnosing pMN and its correlation with PLA2R staining in kidney biopsies in a prospective observational study of 58 adult NS subjects undergoing a kidney biopsy.

Background: There is no robust evidence-based data for ABO-incompatible kidney transplantation (ABOiKT) from emerging countries.

Methods: Data from 1759 living donor ABOiKT and 33 157 ABO-compatible kidney transplantations (ABOcKT) performed in India between March 5, 2011, and July 2, 2022, were included in this retrospective, multicenter (n = 25) study. The primary outcomes included management protocols, mortality, graft loss, and biopsy-proven acute rejection (BPAR).

Objectives: Evidence on living donor kidney transplant procedures when both the donor and recipient have had a history of COVID-19 infection is scarce.

Materials And Methods: We retrospectively explored the protocol, outcomes, and follow-up of 64 donors and recipients of living donor kidney transplant who had recovered from COVID-19. This was a multicenter (n = 12) study from India that included transplants between October 29, 2020, and December 1, 2021.

Introduction: New challenges in dialysis care delivery confront caregivers with the rise in dialysis numbers. There are significant lacunae in the knowledge and efficient application of dialysis therapy in the absence of a dialysis registry. This multicentric study was conducted by the Nephrology Association of Karnataka to systematically study patient demographics and dialysis characteristics in Karnataka state, India, as a basis for a statewide dialysis registry.

COVID 19 infection is an ongoing pandemic that the world is facing currently. Though SARS-CoV2 infection mainly involves the lungs, it is known to affect other organs like kidneys, brain, heart, endocrine organs and gastrointestinal system. It is hypothesized that the ACE2 and transmembrane serine protease 2 which are expressed in the beta cells of the pancreas are the entry receptors for the SARS-CoV-2 virus, thus causing pancreatitis.

Background: There is an enormous knowledge gap on management strategies, clinical outcomes, and follow-up after kidney transplantation (KT) in recipients that have recovered from coronavirus disease (COVID-19).

Methods: We conducted a multi-center, retrospective analysis in 23 Indian transplant centres between June 26, 2020 to December 1, 2021 on KT recipients who recovered after COVID-19 infections. We analyzed clinical and biopsy-confirmed acute rejection (AR) incidence and used cox-proportional modeling to estimate multivariate-adjusted hazard ratios (HR) for predictors of AR.

Diabetic nephropathy (DN) is characterized by progressive increase in proteinuria and decline in renal functions. Various forms of nondiabetic kidney disease may be superimposed on DN, which can alter the progression of DN. Collapsing glomerulopathy (CG) may superimpose on DN, and is characterized by rapid worsening of renal failure and has poor prognosis.

Early post-transplant de-novo pauci-immune necrotizing crescentic glomerulonephritis occurring within the first week post transplantation has not been reported according to the literature search done by us. Here, we are reporting a 56 years male patient who underwent living spousal donor kidney transplantation for presumed diabetic nephropathy, and developed pauci-immune necrotizing crescentic glomerulonephritis (NCGN) on sixth day post-transplant. Post-renal transplant recurrence of disease in ANCA-associated vasculitis patients occurs within days to months.

Background: The effect of coronavirus disease 2019 (COVID-19) on a developing nation is sparsely reported and, more importantly, the discrepancies in public and private sectors are underexplored.

Methods: We retrospectively investigated the data on the effect of COVID-19 on renal transplantation between 2019 and 2020 in a nationwide analysis from 8 public and 10 private sector hospitals of India.

Results: On comparing the yearly data, the number of living-related transplants and deceased donor transplants declined by 48% (2610 vs 1370) and 49% (194 vs 99), respectively.

Article Synopsis
  • A study in India assessed early COVID-19 incidence in kidney transplant recipients (KTR) and found that 2.6% experienced COVID-19 within 30 days post-transplant, among 838 performed from March 2020 to May 2021.
  • Among the 22 KTR patients with early COVID-19, symptoms varied from asymptomatic to severe, with common symptoms including shortness of breath and loss of smell; their mortality rate was not significantly higher than the overall KTR group.
  • The findings indicate a greater severity and mortality in COVID-19 among waitlisted patients compared to KTR, suggesting that KTR may have better outcomes, which could inform decisions regarding

Introduction: Coronavirus disease 2019 (COVID-19) pandemic led to a sudden drop in renal transplant numbers across India in the initial months of 2020. Although the transplant numbers increased with easing of lockdown, the outcome of these transplants remains unknown.

Methods: This was a retrospective, observational, multi-center study done across eight different transplant centers in India.

Patients with chronic kidney disease (CKD) experience high symptom burden, both physical and psychological, that is underrecognized and undertreated. The high symptom burden significantly impacts the quality of life for patients and their families. This review enumerates the various physical and psychological symptoms that patients with CKD often experience and guides in the management of these symptoms.

Background: There is limited current knowledge on feasibility and safety of kidney transplantation in coronavirus disease-19 (COVID-19) survivors.

Dense deposit disease (DDD), earlier called Type II membranoproliferative glomerulonephritis is distinct disease having frequent relapses reaching end-stage kidney disease by 10-year in up to 50%-60% of cases and high recurrence rate in the allograft. The term DDD is derived from its distinctive ribbon-like osmiophilic deposits in the lamina densa of glomerular basement membrane by electron microscopy. Pathogenetically, alternate pathway dysfunction leads to this disease, which is diagnosed by ultrastructure.

We report a case of monoclonal gammopathy of renal significance in a 63-year-old man who presented with nephrotic-range proteinuria and renal insufficiency. The kidney biopsy showed a membranoproliferative glomerulonephritis pattern with extensive crystalloid deposits in the glomerular capillary endothelial cells and very few in the tubular epithelial cells. The immunoperoxidase staining showed kappa light chain restriction.
