Somatosensory Phenotyping of ADPKD

NCT ID: NCT06970028

Last Updated: 2025-11-17

Basic Information

• Recruitment Status: RECRUITING
• Total Enrollment: 150 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2025-09-09
• Study Completion Date: 2026-12-31

Brief Summary

Over 60% of patients with ADPKD suffer from pain, mostly in the abdomen, flank and back, often leading to the diagnosis. It is challenging to manage and cure the pain; approximately 39% of patients are not satisfied with their pain treatment, since the pain prevents them from doing various activities, affecting their quality of life. Pain can be present before enlargement of the kidneys, the source of the pain is often unknown and common analgesics are insufficient to manage the pain or cannot be taken due to renal impairment. By further investigating and characterizing the pain phenotype of the ADPKD population, pain management might be improved and alternative therapeutic approaches might be developed. In this clinical study, pain will be assessed in patients with ADPKD using Quantitative Sensory Testing (QST) on the dominant hand and the lower back, together with four questionnaires regarding pain and quality of life. These results will be compared with the somatosensory profile of matched healthy volunteers.

Conditions

ADPKD; Pain

Study Design

• Observational Model Type: CASE_CONTROL
• Study Time Perspective: CROSS_SECTIONAL

Study Groups

Patients with ADPKD

Patients with ADPKD will be included (≥ 12 years old). The somatosensory profile will be described using Quantitative Sensory Testing and questionnaires regarding pain and quality of life.

Quantitative Sensory Testing

Intervention Type: OTHER

We will perform QST on the dominant hand and lower back.

Questionnaires regarding pain and quality of life

Intervention Type: OTHER

Questionnaires will be filled out by patients with ADPKD to evaluate pain and quality of life.

Healthy volunteers

Healthy volunteers will be included (≥ 12 years old), matched with the patient group based on age, sex and BMI. The somatosensory profile will be described using Quantitative Sensory Testing and the BPI-SF questionnaire.
