Insights

Tyrosine kinase inhibitors combat tumor growth by blocking pathological angiogenesis. However, these effective cancer treatments can cause hypertension and proteinuria, requiring careful patient management.

Area of Science:

  • Oncology
  • Pharmacology
  • Nephrology

Background:

  • Pathological angiogenesis is crucial for tumor cell survival and proliferation.
  • Tyrosine kinases play a key role in pathological angiogenesis.
  • Approved tyrosine kinase inhibitors (TKIs) offer treatment for recurrent and resistant cancers.

Purpose of the Study:

  • To review the incidence and severity of hypertension and proteinuria associated with TKIs.
  • To explore the pathophysiologic mechanisms underlying these TKI-induced side effects.
  • To provide a clinical guide for screening and managing hypertension and proteinuria in patients on TKIs.

Main Methods:

  • Literature review of studies on tyrosine kinase inhibitors.
  • Analysis of reported incidence and severity of hypertension and proteinuria.
  • Examination of pathophysiologic mechanisms.
  • Development of a screening and management guide.

Main Results:

  • Tyrosine kinase inhibitors are linked to the development of hypertension and proteinuria.
  • The incidence and severity vary among different TKIs.
  • Understanding pathophysiologic mechanisms is key to management.

Conclusions:

  • Tyrosine kinase inhibitors are valuable cancer therapeutics but pose risks of hypertension and proteinuria.
  • Proactive screening and management strategies are essential for patient safety and treatment adherence.
  • Further research into TKI-induced nephrotoxicity and cardiovascular effects is warranted.

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
Nephrotic Syndrome II : Assessment and Medical Management01:26

Nephrotic Syndrome II : Assessment and Medical Management

IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document any history...

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...

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 fluid...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
