About this trial

This is an interventional diagnostic trial for Overactive Bladder focused on measuring Neurotrophins, Nerve Growth Factor, Brain-Derived Neurotrophic Factor, Urinary Biomarkers, Urodynamics, Anticholinergics, Children

Eligibility Criteria

3 Years - 18 Years (Child, Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • urgency with or without frequency, incontinence, enuresis, or nocturia
  • an unremarkable clinical examination
  • a minimum of 3 micturitions per day
  • informed oral and written consent from the child and both parents/legal guardian

Exclusion Criteria:

  • acute urinary tract infection
  • diseases of central or peripheral nerve system
  • anomalies of lumbosacral region
  • bladder outlet obstruction
  • operative procedures or anomalies of urinary or genital tract
  • hypercalcuria, diabetes mellitus, diabetes insipidus
  • neurogenic bladder
  • constipation or fecal incontinence
  • urolithiasis, depression, eating disorders or cardio-metabolic diseases
  • prior use of anticholinergic treatment during the last year

Intervention

Arm Description

Patients with overactive bladder will receive anticholinergic therapy: oral oxybutynin in daily dose 0.2-0.5 mg/kg divided in two daily doses for 3 to 6 months depending on treatment outcome assessed 3 months after start of intervention.

Outcomes

Primary Outcome Measures

Initial success
Nonresponse is defined as a 0% to 49% decrease, partial response is defined as a 50% to 89% decrease, response is defined as a 90% or greater decrease and full response is defined as a 100% decrease or less than 1 symptom occurrence monthly. Symptoms include urgency, daily incontinence, increased daytime frequency, enuresis, nocturia. Symptom frequency will be assessed using validated diary.

Secondary Outcome Measures

Long-term success
Relapse is defined as more than 1 symptom recurrence monthly, continued success is de-fined as no relapse in 6 months after the interruption of treatment.
Bladder wall thickness
Bladder wall thickness will be measured using ultrasonography.
Improvement in health-related quality of life measured by PedsQL 4.0 Generic Core questionnaire
Improvement is defined by increase in total and subscale scores by more than defined minimally clinical important difference for PedsQL 4.0 Generic Core questionnaire.
Urinary neurotrophins
Urine samples will be collected at urge sensation before and 6 months after start of intervention. Urinary nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) levels normalized to urinary creatinine will be measured.
Urinary cytokines
Urine samples will be collected at urge sensation before and 6 months after start of intervention. Urinary inflammatory cytokines (MCP-1, MCP-2, MCP-3, CaCL-13) levels normalized to urinary creatinine will be measured.
Urodynamics
Urodynamic study will be investigated prior and 6 months after start of intervention. Maximum detrusor pressure will be assessed.

5. Study Description

Brief Summary
It is a single-center, prospective, interventional, single-arm study. Aim is to investigate which variables are significantly correlated with prolonged anticholinergic treatment (>6 months) in children with overactive bladder (OAB). Investigated variables will include urinary neurotrophins and inflammatory cytokines, sonographic biomarkers, symptom score scale, demographics, and urodynamic findings. Secondary aim is to analyze sensitivity and specificity of urinary biomarkers in diagnosis and management of OAB compared to urodynamics and treatment outcome.
