A Cohort Study on Treating Primary Nocturnal Enuresis by Regulating Central-Peripheral Circadian Rhythm
Sponsor: Shanghai Children's Medical Center
Summary
Primary nocturnal enuresis (PNE), a prevalent pediatric disorder, suffers from therapeutic limitations characterized by low efficacy and high relapse rates. Targeting its core pathophysiology could significantly improve treatment outcomes. Growing evidence implicates circadian dysregulation in PNE pathogenesis. Our preliminary fMRI cohort identified abnormal functional connectivity between the suprachiasmatic nucleus (SCN, the central circadian pacemaker) and superior temporal gyrus in PNE patients, with clinical data confirming circadian realignment correlates with symptom remission. Small-scale pilot studies and clinical observations indicate that modulating central and peripheral circadian rhythms significantly alleviates PNE symptoms. This study will establish a circadian-focused PNE cohort to quantify therapeutic efficacy and elucidate underlying mechanisms, ultimately driving the development of mechanism-based therapies for PNE.

Interventions
Circadian Rhythm Intervention Combined with Bladder Training
Participants diagnosed with primary nocturnal enuresis will be screened at Shanghai Children's Medical Center, and eligible patients will be enrolled. Participants will be randomly assigned to the Bladder Training Combined with Circadian Rhythm Intervention Group, which will receive a 6-month integrated protocol encompassing bladder training and circadian rhythm intervention. The bladder training component includes fluid intake restriction, micturition desire-relaxation training, and sphincter control training. Circadian rhythm interventions involve sleep hygiene education, chronotype-guided bedtime scheduling, and morning bright light therapy.
Bladder Training (basic treatment for enuresis)
Participants diagnosed with primary nocturnal enuresis will be screened at Shanghai Children's Medical Center, and those meeting eligibility criteria will be enrolled. Participants will be randomized to the Bladder Training Only Group, which will receive a 6-month intervention comprising fluid intake restriction, micturition desire-relaxation training, and sphincter control training.
