Urinary tract infections (UTIs) are a common pathology among children, characterized by an infectious process affecting any structures of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections can be caused by various microorganisms, the most common of which are Escherichia coli, Klebsiella, Proteus, and Enterococcus bacteria. UTIs can occur in various forms: from asymptomatic bacteriuria to acute and chronic forms of infection that require intensive medical intervention. In children, UTIs can manifest themselves in a variety of ways, which complicates diagnosis and requires a careful approach to treatment.
History of the disease and interesting historical facts
The study of urinary tract infections dates back to ancient times. The first mentions of symptoms similar to UTIs were found in medical texts from ancient Egypt and Greece. In the 4th century BC, Hippocrates described symptoms similar to cystitis. Over time, in the Middle Ages, doctors began using urine analysis to diagnose various diseases, including urinary tract infections. By the late 19th century, advances in microbiology made it possible to identify the specific pathogens that cause these infections. Modern research focuses on improving diagnostic and treatment methods, as well as studying predisposing factors and recurrent infections.
Epidemiology
Urinary tract infections are among the most common infectious diseases in children. According to various studies, among children under 5, UTIs are diagnosed in approximately 2-3% boys and 5-7% girls. Girls have a significantly higher risk of developing UTIs, which is associated with anatomical features (short urethra, proximity to the anal area). In most cases, infections occur after previous illnesses, as well as as a result of non-compliance with hygiene standards. According to the Association of Pediatricians, up to 30% children who have had their first UTI may experience relapses within a year.
Genetic predisposition to this disease
Research now shows that genetic predisposition plays a role in the development of urinary tract infections. It has been found that certain polymorphisms in genes involved in the immune response can increase a child’s vulnerability to these infections. For example, mutations in genes responsible for the production of immune system catalysts (such as cytokines) can affect their ability to cope with bacterial infections. Genes responsible for metabolism and detoxification have also been shown to influence the development of UTIs, predisposing them to more frequent relapses of the disease.
Risk factors for the development of this disease
The risk of developing urinary tract infections in children is increased by many factors, which can be classified into several groups:
- Anatomical anomalies: various congenital malformations of the urinary system, such as anomalies in the position of the kidneys or obstructions of the urinary tract.
- Functional disorders: presence of neurogenic bladder dysfunction, enuresis or urinary retention.
- Infections: Previous infections or rare infections that may weaken the immune system.
- Poor hygiene: insufficient care of the genital area, especially in girls.
- Hormonal changes: changes during puberty.
Diagnosis of this disease
Diagnosis of urinary tract infections in children includes the following stages:
- Main symptoms: Depending on the location of the infection, frequent urination, burning during urination, pain in the lumbar region, fever and general malaise may be observed.
- Laboratory tests: general urine analysis, which can show the presence of leukocytes, bacteria and nitrites, urine analysis according to Nechiporenko.
- Radiological examinations: Ultrasound of the kidneys and bladder to assess anatomy and possible abnormalities, as well as CT or MRI if complications are suspected.
- Other types of diagnostics: Cystoscopy to assess the condition of the bladder walls and urethra in complex cases.
- Differential diagnosis: It is necessary to exclude other diseases such as pyelonephritis, glomerulonephritis and urethritis.
Treatment
Treatment for urinary tract infections in children can range from observation and supportive measures to more aggressive approaches:
- General treatment: General recommendations include drinking plenty of fluids, practicing good hygiene, and resting.
- Pharmacological treatment: Antibiotic therapy is the main treatment for UTI. The choice of antibiotics depends on the child's age, the severity of the condition, and the nature of the pathogen.
- Surgical treatment: In cases of severe anatomical abnormalities, surgery may be required to correct them.
- Other types of treatment: Herbal medicine and the use of probiotics can be used as a complement to the main treatment.
List of medications used to treat this disease
The most commonly used antibiotics to treat urinary tract infections in children are:
- Amoxicillin
- Cephalosporins (Cephalexin, Cefuroxime)
- Fosfomycin
- Nitrofurantoin
- Trimethoprim/sulfamethoxozole
Disease monitoring
Monitoring a child's condition after a UTI involves monitoring recovery and identifying possible relapses:
- Control stages: regular visits to the doctor to assess the dynamics of the disease, especially in the first months after treatment.
- Forecast: With timely diagnosis and adequate treatment, the prognosis is almost always favorable.
- Complications: Chronic infections or loss of kidney function may develop if left untreated.
Age-related features of the disease
Urinary tract infections in children can present differently depending on age:
- In newborns and infants, UTIs may be asymptomatic; in such children, the condition may deteriorate rapidly.
- Young children are characterized by high fever and crying when urinating.
- Adolescents may describe more complex symptoms, such as painful urination, and often seek medical attention.
