Assessing Molecular Mechanisms and Effects of Music Therapy in Youth With Sickle Cell Disease Using Single-cell RNA-sequencing

2026년 9월 8일 업데이트: Manoj Bhasin, Emory University

The goal of this clinical trial is to evaluate whether a 4-week music therapy (MT) intervention can reduce chronic pain and improve psychosocial outcomes in youth with sickle cell disease (SCD).

The main questions it aims to answer are:

  • Does MT reduce pain intensity, frequency of pain episodes, and improve health-related quality of life (HRQoL)?
  • Does MT alter immune cell composition and gene expression in inflammatory pathways, as measured by single-cell RNA sequencing (scRNA-seq)?

Researchers will compare participants randomized to music therapy versus a control condition to see if MT produces superior improvements in pain and psychosocial outcomes, and distinct molecular changes.

상세 설명

Sickle cell disease (SCD) is an inherited blood disorder that affects approximately 100,000 individuals in the United States, with higher prevalence among people of African and Latin-American descent. Children and adolescents with SCD often experience recurrent vaso-occlusive episodes (VOE) and chronic pain, which contribute to emotional distress, impaired academic performance, reduced daily functioning, and increased hospital utilization. Chronic pain also imposes a substantial financial burden and is associated with anxiety, depression, and diminished quality of life. Current pharmacologic treatments, such as hydroxyurea and blood transfusions, can reduce pain crises but are limited by side effects that interfere with school attendance and social participation, underscoring the need for safe, nonpharmacologic alternatives. Integrative approaches, such as cognitive behavioral therapy (CBT) and music therapy (MT), have been recognized as effective non-pharmacological pain management strategies, with evidence showing improvements in pain, mood, fatigue, and overall quality of life. However, the molecular mechanisms underlying these benefits remain poorly understood, particularly in SCD.

This study will evaluate the effects of a 4-week MT intervention in youth with SCD, focusing on both psychosocial outcomes and molecular mechanisms. The intervention will be delivered using Music Care©, a virtual platform that employs a structured "U" algorithm, beginning with stimulating music, transitioning into relaxation, and concluding with a gentle reintroduction of rhythm and energy. The primary aim is to determine whether MT reduces pain intensity, frequency of pain episodes, stress, anxiety, depression, and improves health-related quality of life (HRQoL). The secondary aim is to investigate changes in immune cell composition and gene expression using single-cell RNA sequencing (scRNA-seq), which will enable detailed profiling of immune cells, including T cells, B cells, monocytes, neutrophils, and granulocytes, as well as their transcriptional states and regulatory networks. Samples will be collected at baseline and endpoint to identify pathways altered by MT and to correlate molecular findings with clinical outcomes.

By integrating psychosocial assessments with single-cell transcriptomic profiling, this study seeks to provide novel insights into how MT modulates immune and inflammatory pathways in pediatric SCD. Understanding these mechanisms may reveal new therapeutic targets, improve patient stratification, and support broader adoption of MT as an evidence-based, nonpharmacologic intervention for chronic pain management in children and adolescents living with SCD.

주요 결과 측정

결과 측정
측정값 설명
기간
Change in Pain characteristics
기간: Baseline, Week 5

The Brief Pain Inventory (BPI) is a validated self-report questionnaire that measures both the severity of pain and the degree to which pain interferes with daily activities.

Pain intensity is rated on a 0-10 numeric scale (0 = no pain, 10 = worst pain imaginable). Pain interference items are also scored 0-10 (0 = does not interfere, 10 = completely interferes). Greater scores indicate more severe pain and greater interference with daily activities.
Baseline, Week 5
Change in Health-related quality of life (HRQoL)
기간: Baseline, Week 5

Parents will complete the Pediatric Quality of Life Inventory (PedsQL) at baseline and Week 5. This parent-proxy measure assesses physical, emotional, social, and school functioning. Changes in HRQoL scores will be analyzed to determine whether music therapy improves overall well-being compared to control.

Scoring: Items are scored on a 0-100 scale, with higher scores reflecting better quality of life (less impairment). Lower scores indicate poorer functioning across physical, emotional, social, and school domains.
