Trial summary

Metabolic dysfunction-associated steatotic liver disease (MASLD) is now the leading cause of chronic liver disease in people living with HIV (PLWH). Currently, there are no approved medications to treat this condition. That's why weight loss through healthy lifestyle changes is the most important way to manage it. Read more about this study

About this study

Metabolic dysfunction-associated steatotic liver disease (MASLD) is now the leading cause of chronic liver disease in people living with HIV (PLWH). Currently, there are no approved medications to treat this condition. That's why weight loss through healthy lifestyle changes is the most important way to manage it.

This study will test if a digital nutritional program (DNP), using a mobile phone app, can help improve weight loss better than the usual advice on healthy eating and exercise.

The study includes people living with HIV, aged 18 and older, with fatty liver (detected by ultrasound or other scans), and on stable HIV treatment.

Participants will be randomly assigned to two groups:

  • Intervention group: Will receive personalized lifestyle support through a mobile app (DNP).
  • Control group: Will receive general advice on healthy habits. The study will last 12 months, with follow-up visits during and after the program.

What Will Be Measured:

  • Weight, waist size, blood pressure, and body fat.
  • Blood tests to check cholesterol, sugar levels, liver enzymes, and other markers.
  • Liver scans to assess fat and stiffness.
  • Questionnaires on eating habits, exercise, and satisfaction with the program.

Goals of the Study:

Main goal: To see how many people lose at least 5% of their body weight after 6 months.

Other goals: To see the effects on weight after 12 months, and 6 months after stopping the program, and to monitor improvements in liver health.

Why This Matters:

This study aims to find new ways to help people with HIV improve their liver health and overall well-being through simple, practical tools like a mobile app.

Being tested
Digital nutritional program, Standard care dietary and exercice advice.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Digital nutritional programBehavioural

    • Web registration and download of the aplication: After signing the informed consent, the investigator will pre-register the participant on a page provided for this purpose. The patient will then receive an email with instructions to registre and download the digital nutritional program The user's pasword will be stored encrypted. Once received, the participant must fill out the start form. This form has the mission of conducting the dietitian-nutritionist on eating habits and lifestyles and to guide nutritional intervention.
    • Digital nutritional program: apply cognitive-behavioural techniques to promote healthy eating for each participant and ensure their understanding of the most important aspects for their Health, regarding their chronic conditions and the treatments they are undergoing. DNP will offer a program that tailors meal plans to patients' specific pathologies and circumstances via a mobile application.
  • Standard care dietary and exercice advice.Behavioural

    Advice on healthy lifestyle recommendations given by a trained physician or nurse, based on a Mediterranean diet (based on fruits, vegetables, legumes, whole grains, fish or white meat and olive oil; avoid processed foods, red meat and sugary drinks). Delivery of written resources containing healthy eating guidelines and advice.

DNP will offer a program that tailors meal plans to patients' specific pathologies and circumstances via a mobile application These plans include detailed recipes, preparation instructions, and an automatic grocery list. Additionally, thematic weeks are incorporated, featuring training guides where patients engage system to address aspects related to their diet and enhance their health and wellbeing. All of these features are implemented within a gamified framework, with daily and weekly points awarded, and challenges incentivising adherence and motivation in their daily routines. The nutritional approach will be based on the Mediterranean diet.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To compare the percentge of people living with HIV and MASLD achieving at least a 5% weight reduction at 6 months, through a randomly asigned behavioral intervention on lifestyle using a digital nutritional program or standard advice.

    We will compare the percentage of participants who achieve a body weight reduction of ≥ 5% between the two arms, at month 6.

    Measured: From enrollment to month 6

Secondary outcomes (19)

  16. To evaluate changes in dietary habits at 6 and 12 months, and 6 months after DNP discontinuation.

    To assess dietary habits Mediterranean Diet Adherence Questionnaire will be used. The questionnaire includes key dietary components (fruits, vegetables, legumes, fish, olive oil, meats, beverages). Each item is scored according to the scale criteria. Minimum value 0, maximum value 14. Higher scores indicate greater adherence. A score above 10 indicates good adherence to the Mediterranean diet. A score <7 indicates low adherence.

    Measured: From enrollment to month 6, 12 and 6 after Digital Nutritional Program discontinuation.

  17. To evaluate changes physical actvity at 6 and 12 months, and 6 months after DNP discontinuation.

    To assess physical activity we use Physical Activity Questionnaire-Short Form. The IPAQ-SF is a 7-item questionnaire designed to estimate the frequency and duration of physical activity performed during the previous 7 days.

    The questionnaire assesses three intensity levels of activity:

    • Vigorous-intensity activities (e.g., running, aerobic exercise, competitive sports)
    • Moderate-intensity activities (e.g., carrying light loads, cycling at a regular pace, recreational swimming)
    • Walking Data Collected for each activity: Number of days per week they performed the activity, average time per day.

    Unit: Metabolic Equivalent Task minutes per week (MET-minutes/week):

    • Walking: 3.3 METs
    • Moderate activity: 4.0 METs
    • Vigorous activity: 8.0 METs The total physical activity score :MET value×minutes per day×days per weeK Participants are classified in 3 cathegories:ow (<600 MET-min/week), moderate (600-2999 MET-min/week), and high (≥3000 MET-min/week)

    Measured: From enrollment to month 6, 12 and 6 after Digital Nutritional Program discontinuation

  18. To evaluate digital nutritional program adherence at 6 and 12 months.

    Data to evaluate adherence will by recorded by the digital program based on the participant's usage. A patient is considered adherent if he has been accessing the program for a minimum period of 30 calendar days in 6 months.

    Measured: Data are assessed at 6 and 12 months

  19. To evaluate changes on health-related quality of life at 6 and 12 months, and 6 months after DNP discontinuation.

    To assess health-related quality of life we use the Euro quality of life 5 dimensions (EuroQoL-5D) health questionnaire. This self-reported instrument evaluates mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Three dimension level is used. Responses across the five dimensions were converted into a utility index using population value sets, ranging from values below 0 (health states worse than death) to 1 (perfect health).

    Measured: From enrollment to month 6, 12 and 6 after Digital Nutritional Program discontinuation
