Insights

Immune checkpoint inhibitors can cause rare kidney problems. This review covers how to identify, manage, and prevent these immune-related adverse events (irAE), including in patients with existing kidney disease.

Area of Science:

  • Oncology
  • Nephrology
  • Immunology

Background:

  • Immune checkpoint inhibitors (ICIs) are increasingly used for various cancers.
  • Renal immune-related adverse events (irAEs) are uncommon but significant complications of ICIs.
  • Early recognition and management of renal irAEs are crucial for patient outcomes.

Purpose of the Study:

  • To provide a comprehensive review of renal irAEs associated with ICIs.
  • To summarize current knowledge on clinical presentation, pathology, and management strategies.
  • To discuss ICI safety in patients with pre-existing chronic kidney disease and kidney transplant recipients.

Main Methods:

  • Literature review of clinical studies and case reports on renal irAEs.
  • Analysis of data on incidence, clinical features, and histopathology.
  • Synthesis of current guidelines and expert opinions on management.

Main Results:

  • Renal irAEs manifest in diverse clinical and pathological patterns.
  • Prompt diagnosis and appropriate immunosuppressive therapy can lead to favorable outcomes.
  • Specific considerations are necessary for managing patients with chronic kidney disease and transplant recipients.

Conclusions:

  • Renal irAEs are a manageable toxicity of ICIs.
  • Physicians must be vigilant in monitoring for and treating renal complications.
  • Further research is needed to optimize ICI use in vulnerable kidney populations.

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Acute Kidney Injury II: Pathophysiology

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
