Renal Diseases and Glomerulopathies
Research Guide
What is Renal Diseases and Glomerulopathies?
Renal diseases and glomerulopathies are a cluster of disorders affecting the glomeruli of the kidney, encompassing pathophysiology, genetics, and clinical features of conditions such as nephrotic syndromes including membranous nephropathy, focal segmental glomerulosclerosis, and IgA nephropathy, along with podocyte biology, renal thrombotic microangiopathy, genetic kidney diseases, and kidney barrier function.
This field includes 78,765 works on glomerular diseases and related nephrotic syndromes. Key areas cover podocyte biology, genetic kidney diseases, and kidney barrier function in disease progression. Growth rate over the past five years is not available.
Topic Hierarchy
Research Sub-Topics
Podocyte Biology in Glomerular Disease
This sub-topic explores podocyte structure, slit diaphragm proteins like nephrin, and injury mechanisms. Researchers study effacement, apoptosis, and regeneration using models.
Membranous Nephropathy Pathogenesis
This sub-topic covers anti-PLA2R antibodies, PLA2R/THSD7A antigens, and immune complex deposition. Studies evaluate rituximab efficacy and biomarker monitoring.
Focal Segmental Glomerulosclerosis
This sub-topic addresses primary/secondary FSGS, podocin mutations, and circulating permeability factors. Researchers classify collapsing/hypertrophic variants and trial SGLT2 inhibitors.
IgA Nephropathy Mechanisms
This sub-topic investigates galactose-deficient IgA1, anti-glycan antibodies, and mesangial proliferation. Clinical trials target MEST score and proteinuria endpoints.
Genetic Kidney Diseases Glomerulopathies
This sub-topic focuses on monogenic forms like Alport syndrome, Pierson, and familial FSGS genes (NPHS1/2). Researchers apply next-gen sequencing for diagnostics.
Why It Matters
Accurate estimation of glomerular filtration rate (GFR) using equations like the one developed by Levey et al. enables precise diagnosis and monitoring of kidney function in chronic kidney disease patients, with the 4-variable MDRD Study equation providing reasonable accuracy for GFR less than 90 mL/min per 1.73 m² when using standardized serum creatinine (Levey et al., 2006). In advanced clear-cell renal-cell carcinoma, sorafenib treatment prolongs progression-free survival compared to placebo, as shown in a trial with NCT00073307, though it increases toxic effects (Escudier et al., 2007). A systematic approach to differential diagnosis of glomerular disease, as outlined by Hebert et al. (2013), assists clinicians in deciding on biopsy timing and initial treatments. Diabetic kidney disease affects approximately 40% of diabetic patients and represents the leading cause of chronic kidney disease worldwide, with most patients succumbing to cardiovascular diseases or infections before end-stage renal disease (Alicic et al., 2017).
Reading Guide
Where to Start
"A New Equation to Estimate Glomerular Filtration Rate" by Levey et al. (2009), as it provides the foundational method for assessing kidney function central to evaluating all glomerular diseases.
Key Papers Explained
Levey et al. (2009) introduced a primary equation for GFR estimation, refined by Levey et al. (2006) using standardized serum creatinine in the MDRD Study for improved accuracy below 90 mL/min per 1.73 m². Hebert et al. (2013) build on this by offering a systematic differential diagnosis approach for glomerular diseases, aiding clinical decisions informed by GFR data. Matsushita et al. (2010) link estimated GFR and albuminuria to mortality risks, extending prognostic applications, while Escudier et al. (2007) apply GFR context to sorafenib outcomes in renal-cell carcinoma.

Frequently Asked Questions
What equation estimates glomerular filtration rate?
A new equation to estimate glomerular filtration rate was developed using data from the National Institute of Diabetes and Digestive and Kidney Diseases (Levey et al., 2009). The 4-variable MDRD Study equation provides reasonably accurate GFR estimates in patients with chronic kidney disease and measured GFR below 90 mL/min per 1.73 m² when using standardized serum creatinine (Levey et al., 2006).
How is glomerular disease differentially diagnosed?
Differential diagnosis of glomerular disease follows a systematic and inclusive approach that addresses clinical uncertainties such as biopsy necessity and timing (Hebert et al., 2013). This evidence- and experience-based method guides whether to treat before or after biopsy.
What is the role of sorafenib in renal-cell carcinoma?
Sorafenib prolongs progression-free survival in patients with advanced clear-cell renal-cell carcinoma who failed prior therapy, compared to placebo (Escudier et al., 2007). Treatment is linked to increased toxic effects, as per ClinicalTrials.gov NCT00073307.
What defines diabetic kidney disease?
Diabetic kidney disease develops in about 40% of diabetic patients and is the leading cause of chronic kidney disease worldwide (Alicic et al., 2017). Most patients die from cardiovascular diseases or infections before reaching end-stage renal disease.
How are systemic vasculitides classified?
The Chapel Hill Consensus Conference provides nomenclature for systemic vasculitides, using patient age to discriminate between Takayasu arteritis and giant cell arteritis (Jennette et al., 1994).
What is the Banff classification for renal allografts?
The Banff 97 working classification standardizes renal allograft pathology assessment (Racusen et al., 1999).
