Insights

Focal and segmental glomerulosclerosis (FSGS) is the most common glomerular disease in Colombia. Immunoglobulin A nephropathy (IgAN) is more prevalent in this population than in Afro-Americans, with reasons yet to be determined.

Area of Science:

  • Nephrology
  • Epidemiology
  • Pathology

Background:

  • Glomerular diseases represent a significant cause of kidney disease globally.
  • Understanding regional variations in glomerular disease prevalence is crucial for public health and clinical practice.
  • Epidemiological data inform clinical management and guide future research priorities.

Purpose of the Study:

  • To determine the frequency of various glomerular diseases in a Colombian population.
  • To establish a baseline for future epidemiological studies on renal diseases in Latin America.
  • To compare the prevalence of glomerular diseases with other populations.

Main Methods:

  • A single-center retrospective analysis was conducted at the University of Antioquia, Colombia.
  • Native renal biopsies performed between July 1998 and December 2007 were reviewed.
  • Diagnoses were based on integrated histological, immunopathological, and clinical findings.

Main Results:

  • A total of 1,040 renal biopsies were analyzed, with 79.6% diagnosed with primary glomerular diseases.
  • Focal and segmental glomerulosclerosis (FSGS) was the most common primary glomerular disease (34.8%), followed by immunoglobulin A nephropathy (IgAN) (11.8%).
  • In children (≤15 years), FSGS, postinfectious GN, and minimal change disease (MCD) were most frequent, while in adults, FSGS, IgAN, and membranous glomerulonephritis (MGN) predominated.

Conclusions:

  • FSGS is the leading glomerulopathy in this Colombian cohort, similar to Afro-American populations.
  • A higher prevalence of IgAN was observed compared to Afro-American populations, though the reasons remain unclear.
  • This study provides valuable insights into the epidemiology of renal diseases within Latin America.

Renal Corpuscle01:20

Renal Corpuscle

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...

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...

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...

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...

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area. This equation is...
Renal Drug Excretion: Glomerular Filtration01:02

Renal Drug Excretion: Glomerular Filtration

The kidney serves as the primary organ responsible for eliminating drugs and their metabolites from the body. This process, known as renal elimination, starts with glomerular filtration and results in urine formation. Each kidney houses millions of functional units called nephrons, where urine production occurs. A nephron has two main components: a renal corpuscle and a renal tubule.
Drugs gain access to the kidney via the renal artery, which progressively branches off into afferent arterioles.
