Clozapine-Induced Granulomatous Interstitial Nephritis: A Case Report.

Granulomatous interstitial nephritis is a rare form of tubulointerstitial nephritis and has been uncommonly observed with clozapine usage. Additionally, the progression of the disease to manifest as renal failure requiring dialysis is also uncommon. We describe a case of a 56-year-old female who presented with syncope and was diagnosed with granulomatous interstitial nephritis on biopsy.

Uremic Pericarditis with Cardiac Tamponade in a Patient on Hemodialysis.

Uremic pericardial effusion and pericarditis in end-stage kidney disease patients remain one of the causes responsible for high rates of morbidity and occasional mortality. While clinical presentation could be variable, clinicians should have a high index of suspicion for uremic pericarditis especially in patients who miss their dialysis sessions. We present a 77-year-old man with end-stage renal disease on dialysis diagnosed with pericarditis and large pericardial effusion complicated by cardiac tamponade and shock.

Amlodipine Overdose in a Transgender Woman: A Case Study.

Calcium channel blockers are a major cause of cardiovascular toxicity. The clinical spectrum of these patients is very variable and there is no consensus on the dose required for toxicity. We present a case of a 43-year-old transgender woman who presented with hypotension and tachycardia owing to drug overdose that was later confirmed to be amlodipine.

A Case of Antineutrophil Cytoplasmic Antibody Vasculitis-Associated Acute Kidney Injury in a Patient With Asymptomatic COVID-19 Infection.

Vasculitis, or inflammation of blood vessels, is commonly seen with severe acute respiratory syndrome Coronavirus disease 2 (SARS-CoV-2). It is usually triggered by an autoimmune response induced by the virus, infection by the virus itself and trauma to the epithelial vessels caused by the release of cytokines. We present a case of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (pauci-immune crescentic glomerulonephritis [GN]) superimposed on acute kidney injury caused by SARS-CoV-2.

Acute Dystonia With Rhabdomyolysis Induced by Paliperidone Palmitate: A Rare Adverse Effect.

Antipsychotic medications have been well-established to potentially cause extrapyramidal side effects (EPS) including hyperkinesia, tremor, dyskinesia, dystonia, and parkinsonism. Rhabdomyolysis secondary to extrapyramidal symptoms in patients under antipsychotics is a relatively rare presentation to be observed in patients.  In this report, we present a 64-year-old female with rhabdomyolysis following a once-monthly injection of long-acting injectable (LAI) paliperidone palmitate (Invega Sustenna).

Drug Rash With Eosinophilia and Systemic Symptoms (DRESS) Syndrome Due to Vancomycin.

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a severe adverse drug reaction characterized by skin rash, fever, lymph node enlargement, and single or multiple organ involvement. Prompt diagnosis and withdrawal of the offending drug reduce mortality. We report a case of DRESS syndrome along with a review of the literature.

Metformin-Associated Lactic Acidosis: A Case Report and Review.

Metformin is widely prescribed as the first-line medication for type II diabetes mellitus. While the gastrointestinal side effects of metformin such as nausea, vomiting, diarrhea, and heartburn are quite common, one dangerous side effect of metformin, lactic acidosis, is extensively discussed yet rarely reported. Here, we discuss a 53-year-old female with type II diabetes mellitus who presented to an emergency department (ED) with chief complaints of dizziness and lightheadedness.

A Rare Case of Nephrotic-Range Proteinuria in Antineutrophil Cytoplasmic Antibodies (ANCA)-Associated Vasculitis.

Granulomatosis with polyangiitis (GPA), or Wegener's granulomatosis as it was formerly referred to, is an antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). GPA is characterized as a necrotizing vasculitis with few or no immune deposits termed pauci-immune deposits, predominantly affecting small and medium arterial vessels, involving the upper and lower respiratory tract as well as glomeruli. Renal manifestations are of critical importance because of the progression that may ensue following onset.

Acute Kidney Injury Incidence, Stage, and Recovery in Patients with COVID-19.

Purpose: To determine the incidence, mortality, stage, and recovery of acute kidney injury (AKI) in COVID-19 patients and further analyze the effect of patient demographics and comorbidities on AKI incidence.

Study Design: Our study looked at 1545 charts of patients over 18 years old who presented to BronxCare Hospital in NY with a positive SARS-CoV-2 PCR test. Using the KDIGO criteria, any patient presenting with a creatinine of 1.

Lupus-Mediated Kidney Damage: Lupus Nephritis or Collapsing Glomerulopathy?

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease. It has a myriad of presentations and can involve almost every organ. Its effects on the kidney hold critical importance because patients can ultimately progress to end-stage renal disease (ESRD) if inadequately treated.

Parathyroidectomy as a Cure for Calciphylaxis in a Non-Dialysis Chronic Kidney Disease Patient?

BACKGROUND Calciphylaxis is a rare and fatal systemic disease which most commonly occurs in patients with end-stage renal disease. It is a poorly understood vascular calcification with unclear pathology that leads to vascular compromise due to vascular occlusion with endoluminal calcification. CASE REPORT We report a case of a 61-year-old male with chronic kidney disease stage 5 who developed calciphylaxis.

A Case of Hypokalemia Possibly Induced by Nafcillin.

(1) Background: The use of intravenous antibiotics for severe infections is a common practice, either as inpatient or outpatient treatment. In the case of methicillin-susceptible (MSSA), nafcillin is a commonly prescribed intravenous antibiotic, given its known efficacy to treat infections related to this organism effectively. However, it is not without side effects.

Preoperative Evaluation in Patients With End-Stage Renal Disease and Chronic Kidney Disease.

Optimal preoperative management of dialysis patients remains challenging. Patients with end-stage renal disease (ESRD) have higher mortality in the perioperative setting compared with non-ESRD patients. However, it is well established that dialysis should be done on the day before surgery.

Relationship between platelet count and hemodialysis membranes.

Background: One factor associated with poor outcomes in hemodialysis patients is exposure to a foreign membrane. Older membranes are very bioincompatible and increase complement activation, cause leukocytosis by activating circulating factors, which sequesters leukocytes in the lungs, and activates platelets. Recently, newer membranes have been developed that were designed to be more biocompatible.

Alport's Syndrome in Pregnancy.

Background. Alport's syndrome is an X-linked hereditary disorder affecting the glomerular basement membrane associated with ocular and hearing defects. In women, the disease is much less severe compared to that in men.

Treatment of confirmed B12 deficiency in hemodialysis patients improves Epogen® requirements.

Background: Vitamin B12 deficiency may have deleterious effects on end stage renal disease (ESRD) patients on maintenance hemodialysis, and may increase erythropoietin stimulating agent (ESA) resistance, yet little is known about its prevalence in this population.

Methods: Serum vitamin B12 and methylmalonic acid (MMA) levels were drawn from ESRD patients prior to hemodialysis. All patients with MMA levels greater than 800 nmol/L had peripheral smears evaluated for B12 deficiency.

Diabetes insipidus: a challenging diagnosis with new drug therapies.

Diabetes Insipidus (DI) is either due to deficient secretion of arginine vasopressin (central) or to tubular unresponsiveness (nephrogenic). Drug induced DI is a well-known entity with an extensive list of medications. Polyuria is generally defined as urine output exceeding 3 liters per day in adults.

Neutrophil-to-lymphocyte ratio as a predictor of worsening renal function in diabetic patients (3-year follow-up study).

Background: Previous studies have demonstrated the role of inflammation in diabetic nephropathy (DN). Neutrophil to lymphocyte ratio (NLR) rather than other white cell parameters was found to be a useful inflammatory marker to predict adverse outcomes in medical and surgical conditions. Nevertheless, the value of NLR in predicting DN has not been elucidated.
