Insights

Vitamin D receptor (VDR) gene variations influence susceptibility to urinary tract infections (UTI) in children. The FokI polymorphism significantly increases UTI risk, while ApaI may offer protection.

Area of Science:

  • Genetics
  • Immunology
  • Pediatrics

Background:

  • Vitamin D receptor (VDR) alleles impact infection susceptibility.
  • Urinary tract infections (UTI) are common in children and can lead to renal scarring.

Purpose of the Study:

  • To investigate the association between VDR gene polymorphisms and UTI in children.
  • To determine if specific VDR genotypes influence UTI risk or protection.

Main Methods:

  • Case-control study involving 92 children with UTI and 105 controls.
  • Analysis of VDR gene polymorphisms: BsmI, FokI, ApaI, and TaqI.

Main Results:

  • FokI polymorphism, specifically the ff genotype, showed a significant 3.94-fold increased risk of UTI (p < 0.01).
  • ApaI polymorphism was significantly more prevalent in the control group, suggesting a protective role (p < 0.01).
  • BsmI and TaqI polymorphisms did not show statistically significant associations with UTI risk.

Conclusions:

  • VDR gene polymorphisms, particularly FokI and ApaI, are associated with UTI susceptibility and potentially renal scar formation in children.
  • These findings align with vitamin D's role in modulating immune responses to infections.

Urinary Tract Infection II: Pathophysiology

The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

Urinary Tract Infection I: Introduction

Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

Microbiota of the Urogenital Tract

The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
