The evolution of performing a kidney biopsy: a single center experience comparing native and transplant kidney biopsies performed by interventional radiologists and nephrologists.

Background: Kidney biopsy is the most vital tool guiding a nephrologist in diagnosis and treatment of kidney disease. Over the last few years, we have seen an increasing number of kidney biopsies being performed by interventional radiologists. The goal of our study was to compare the adequacy and complication rates between kidney biopsies performed by interventional radiology versus nephrology.

Paxlovid (Nirmatelvir/Ritonavir) and Tacrolimus Drug-Drug Interaction in a Kidney Transplant Patient with SARS-2-CoV infection: A Case Report.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has had a significant impact on communities and health systems. New antiviral medications against this disease have not been properly tested yet, and their efficiency, side effects, and drug-drug interactions are not entirely known. Organ transplant recipients receive immunosuppressive medications such as tacrolimus to prevent graft rejection.

Impact of age mismatch between donor and recipient on heart transplant mortality.

The effect of donor-to-recipient (D-R) age mismatch in adult heart transplant population is not clearly described, and we undertook this study to determine the impact of age mismatch on mortality. Heart transplant recipients from 2000 to 2017 were identified using the United Network of Organ Sharing database. The cohort was divided into three groups: donor age within 5 years of recipient age (Group 1), donors >5 years younger than recipient (group 2), and donors >5 years older than recipients (Group 3).

Proton Pump Inhibitor-Induced Galactorrhea in a Kidney Transplant Recipient: A Friend or Foe?

Over the last decades, proton pump inhibitors (PPIs) have been widely used as the mainstay for treatment and prevention of gastrointestinal side effects, gastroesophageal reflux, and peptic ulcer disease. However, their safety profile has come into question recently after reports relating them to several side effects as well as kidney disease. Omeprazole, one of the mainly used PPIs, is almost entirely metabolized by the liver but the resulting metabolites are renally excreted.

Caroli Disease Revisited: A Case of a Kidney Transplant Patient With Autosomal Polycystic Kidney Disease and Recurrent Episodes of Cholangitis.

Polycystic kidney disease (PKD) is a genetic disorder leading to end-stage renal disease more commonly in the fourth to sixth decades of life. Cyst formation in the kidneys and other organs such as the liver and pancreas is the main characteristic of this disease. A significant number of patients with PKD undergo kidney transplantation and receive significant immunosuppression, predisposing them to comorbidities such as infections and malignancies.

Impact of Ethylene Glycol Toxicity on Donor Organ Viability: A Case Report.

Using kidneys from deceased donors whose demise was secondary to ethylene glycol (EG) toxicity requires considerable thought and planning. The exact impact that kidneys from these donors could have is unclear. The shortage of viable organs and growing wait list mortality should lead us to consider these allografts as potential life-saving transplants.

Frequency of COL4A3/COL4A4 mutations amongst families segregating glomerular microscopic hematuria and evidence for activation of the unfolded protein response. Focal and segmental glomerulosclerosis is a frequent development during ageing.

Familial glomerular hematuria(s) comprise a genetically heterogeneous group of conditions which include Alport Syndrome (AS) and thin basement membrane nephropathy (TBMN). Here we investigated 57 Greek-Cypriot families presenting glomerular microscopic hematuria (GMH), with or without proteinuria or chronic kidney function decline, but excluded classical AS. We specifically searched the COL4A3/A4 genes and identified 8 heterozygous mutations in 16 families (28,1%).

Preserved endocrine function in a pancreas transplant recipient with pancreatic panniculitis and antibody-mediated rejection.

Pancreas transplantation is an effective treatment option for patients with complicated diabetes mellitus. Pancreas allograft recipients are followed with laboratory markers such as serum amylase, lipase and glucose levels. Hyperglycemia may indicate severe acute rejection and has recently been associated with antibody-mediated (humoral) rejection.

Four cases of nafcillin-associated acute interstitial nephritis in one institution.

Background: Over the course of 1 year, four patients in a single institution developed acute kidney injury most likely secondary to nafcillin-associated acute interstitial nephritis, indicating that this complication might not be as rare as is commonly believed. The main case presented here is that of a 73-year-old man with a history of chronic low back pain who presented with worsening back pain, as well as nausea, vomiting and volume depletion. Imaging studies revealed a soft tissue abscess in the left psoas major muscle.

Molecular investigation and long-term clinical progress in Greek Cypriot families with recessive distal renal tubular acidosis and sensorineural deafness due to mutations in the ATP6V1B1 gene.

The spectrum of distal renal tubular acidosis (dRTA) includes a genetically heterogeneous group of inherited conditions of both autosomal-dominant and recessive mode of inheritance. The basic defect is linked to the renal part of acid-base homeostasis, which is partly achieved by the regulated luminal secretion of H+ at the apical surface of the alpha-intercalated cells of renal collecting ducts. This is coupled to bicarbonate reabsorption with chloride counter transport across the basolateral membranes.
