Aligning home parenteral nutrition with the body clock
Official title: Chronobiology and Chronodisruption in People Receiving Medical Nutritional Therapy and Its Impact on the Quality of Life of Patients and Caregivers. A Descriptive and Interventional Study. Chronumet.
Run by Fundación Pública Andaluza para la Investigación de Málaga en Biomedicina y Salud · NCT07554703 · Data updated 2026-11-12
This trial will test whether changing the timing of overnight home parenteral nutrition to better match patients' natural body clocks improves metabolism, sleep, and quality of life for people on home parenteral nutrition.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are clinically and metabolically stable outpatients who have received nighttime home parenteral nutrition for at least two consecutive months, can provide informed consent and complete questionnaires, and are referred from participating Andalusian hospitals or the NUPA association.
✕Probably not a fit
Patients with known sleep or circadian rhythm disorders, those taking melatonin, or those with recent acute illness, hospitalization, transfusion, or major recent changes in diet or activity are unlikely to benefit or may be excluded.

What this trial studies
Outpatients who have received nighttime home parenteral nutrition for at least two months will be recruited from participating Andalusian centers and the NUPA association and studied at Hospital Regional Universitario de Málaga/FIMABIS. The protocol examines biological rhythms (including clock gene markers), metabolic measures for carbohydrate, lipid and protein metabolism, sleep measures, chronotype, and quality-of-life questionnaires. Eligible participants must be clinically and metabolically stable, able to consent and complete questionnaires, and without recent hospitalization or acute illness. Known sleep/circadian disorders and melatonin use are exclusion criteria, and the study focuses on whether synchronising nutrition timing reduces chronodisruption and related impairments.
Why it matters
Potential benefit: If successful, synchronising parenteral nutrition timing with circadian rhythms could improve metabolic control, sleep quality, and overall well-being for patients on home parenteral nutrition.
How similar studies have gone: Animal studies and small human trials suggest timing of nutrition can affect metabolism and sleep, but applying chronobiology principles specifically to home parenteral nutrition is a relatively novel and limitedly tested approach.
