Outcome Measures

Primary Outcomes (1)

  • Minimal Disease Activity (MDA) which is a composite outcome measure

    5 of 7 of the following criteria: Tender joint count ≤ 1 Swollen joint count ≤ 1 PASI ≤ 1or BSA ≤ 3 Patient pain VAS ≤ 15 Patient global activity VAS ≤ 20 HAQ ≤ 0.5 Tender entheseal points ≤ 1 BSA: body surface area; HAQ: Health Assessment Questionnaire; PASI

    6 months

Study Arms (2)

Patients with PsA and obesity

ACTIVE COMPARATOR

Very Low Energy Diet (VLED)

Dietary Supplement: Very Low Energy Diet (VLED)

Patients with obesity

Dietary Supplement: Very Low Energy Diet (VLED)

Interventions

Very Low Energy Diet (VLED)DIETARY_SUPPLEMENT

Very Low Energy Diet (VLED), divided into 4 daily doses, gives any intake of 640 calories per day together with the recommended doses of vitamins and minerals. During an initial period of 12 weeks the patients only consume VLED. After the strict period food is successively reintroduced during a period of 18 weeks.
