Recent advances in the understanding of immunoglobulin A nephropathy (IgAN) pathogenesis have led to a rapidly expanding therapeutic landscape for the condition. Treatments have historically relied on optimized supportive care aimed at controlling blood pressure and reducing proteinuria through blockading of the renin-angiotensin system and inhibition of the sodium glucose cotransporter 2. Growing insights into immune dysregulation, mucosal immunity, complement activation, and maladaptive hemodynamic responses have facilitated the development of multiple disease-targeting therapies for IgAN. These include agents that modulate mucosal immune responses, inhibit APRIL (a proliferation-inducing ligand) and BAFF (B-cell activating factor) signaling, block complement activation, or target endothelin-mediated pathways. Several of these therapies have shown promising antiproteinuric and kidney-protective effects in clinical trials. This review summarizes recent advances in the treatment of IgAN, with a particular focus on therapies targeting disease-specific pathogenic drivers and their implications for future therapeutic strategies.

Nephrotic Syndrome III : Nursing Management

Nursing management for nephrotic syndrome adapts as the disease progresses, with strategies evolving to address advancing symptoms and complications.Early-Stage Management In the early stages, nursing interventions for nephrotic syndrome resemble those used in managing acute glomerulonephritis, focusing on symptom monitoring, fluid balance, and managing mild to moderate edema.Vital Signs: Regularly monitor blood pressure, pulse, respiratory rate, and temperature to promptly identify...

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...

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Nephrotic Syndrome I : Introduction01:24

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...
Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
