Intervenciones dietéticas en la artritis psoriásica (DIPSA)

Comparador activo: Dieta 1

La dieta 1 se centrará en el patrón dietético y controlará los tipos de alimentos, la nutrición complementaria y brindará apoyo nutricional con un dietista.

Otro: Dieta 1

La dieta 1 se centrará en qué alimentos se comen y el impacto en los resultados de la enfermedad.

Comparador activo: Dieta 2

La dieta 2 se centrará en el patrón dietético y controlará la cantidad de alimentos, la nutrición complementaria y el apoyo nutricional con un dietista.

Otro: Dieta 2

Esta dieta limitará la cantidad de energía alimentaria consumida cada día y el impacto en los resultados de la enfermedad. Esto estará determinado por factores que incluyen la demografía del sujeto (edad, sexo, peso, altura).

Sin intervención: Dieta 3

La Dieta 3 se centrará en patrones dietéticos saludables y brindará apoyo nutricional con un dietista.

Change in Disease Activity in Psoriatic Arthritis (DAPSA)

Disease Activity in Psoriatic Arthritis (DAPSA) is a total of the 5 elements listed below to assess disease activity from both clinical and patient-reported data. The total score falls within a range to indicate level of disease activity: 0-4 = Remission (minimum); 5-14 = Low; 15-28 = Moderate; >28 = High Disease Activity. There is no theoretical upper limit to the DAPSA score.

Total DAPSA score = TJ (Tender Joints) + SJ (Swollen Joints) + CRP (C-reactive protein) + Activity + Pain

1. Tender Joints Count (0-68 joints)
2. Swollen Joints Count (0-66 joints)
3. CRP (mg/dl)

4. Patient's assessment of disease activity and pain:

   1. How active was your rheumatic disease on average during the last week? Scale of 1-10 (Not Active -Active)
   2. How would you describe the overall level of joint pain during the last week? Scale of 1-10 (None-Very Severe)

Patient Reported Outcomes-Psoriatic Arthritis Disease Impact

-Psoriatic Arthritis Disease Impact- Psoriatic Arthritis Impact of Disease (PSAID). The PsAID is a measure developed by the European League Against Rheumatism (EULAR) and is composed of domains selected by an international group of patients with psoriatic arthritis. The questionnaire uses a weighted scoring system (weights were derived by patient impression of importance) and has a range of 0-10. A lower score indicates lower impact of disease from the patient perspective, and a score of 4 is considered a patient acceptable symptom state.

Patient Reported Outcomes-Fatigue

-Fatigue- PROMIS (Patient-Reported Outcomes Measurement Information System) Fatigue (CAT) The PROMIS Fatigue scale assesses fatigue experience and impact of fatigue over 7 days. The instrument includes items on exhaustion and ability to function normally in physical, social, mental and family roles and activities. This instrument has good content validity and responsiveness in rheumatoid arthritis, a similar inflammatory arthritis. We will use the CAT (Computerized Adaptive Test) response instrument. PROMIS uses Item Response Theory (IRT) statistical model that links individual questions to a presumed underlying trait or concept of global health represented by all items in the scale; instruments are scored using item-level calibrations ("response pattern scoring") in an online tool (T-Score range 0-100, where 50 is the mean with a standard deviation of 10). Increasing score indicates higher level of fatigue.
