Qualitative validation of audiovisual educational material for use on rheumatoid arthritis patients

Medication compliance is critical to achieve therapeutic efficacy in patients with rheumatoid arthritis; however, among other factors, low patient-health literacy plays a negative role. Therefore, the development and validation of audiovisual educational material with the participation of health specialists and patients could lead to an improved level of compliance with treatment, while favoring its acceptance. To design and validate audiovisual educational material generated by a multidisciplinary and participative group of patients and health specialists. This study was carried out using a sequential methodology, including qualitative and quantitative techniques: (1) a non-participative observational study with patients and a non-systematic literature search were performed to identify conceptual topics. (2) Pilot videos were qualitatively assessed by patients and health specialists (focus groups and expert committees). (3) Improved versions of seven videos were quantitatively evaluated by patients and specialists following qualitative criteria of attraction, understanding, involvement, acceptance and induction of action. 74 patients with RA, 10 rheumatologists, 4 pharmacists and 2 medical anthropologists participated in the different phases of validation. A total of seven videos lasting 3 min each were generated, incorporating the most relevant suggestions by patients and healthcare professionals. The final version of the videos led to a mean compliance of 96.04 ± 5.2%, according to a representative group of patients and a mean 89.6 ± 9.4%, according to health professionals. With the participation of both patients and health specialists, seven audiovisual educational video recordings were developed and validated, reaching high levels of compliance in accordance with international criteria.

Leptin and adiponectin as predictors of disease activity in rheumatoid arthritis

OBJECTIVES

To assess whether baseline levels of leptin and adiponectin predict disease activity or response to treatment in patients with RA at 6 months, 1 and 2 years of follow-up.

METHODS

A consecutive cohort of patients, classified according to the 2010 ACR/EULAR RA criteria, was evaluated at baseline, 6 months, 1 and 2 years. All were treated with steroids and/or DMARDs. None received biologics. Blood was taken at a baseline to determine plasma anti-CCP, leptin and adiponectin. The relationship between leptin, adiponectin, DAS28 and changes in DAS28 was assessed by multivariable linear and logistic regression from baseline to follow-up.

RESULTS

127 patients completed 6 months, 91 one year and 52 two years of follow-up. All were female, mean age 45 years (18-70), time since onset of disease 7.5 years (0-36). A U-shaped relationship between DAS28 and leptin baseline levels was seen. Adjusting for different factors, leptin levels at baseline predicted higher DAS28 at 6 months and, in patients who were not overweight or obese, predicted disease activity at 6 months, 1 and 2 years. In patients who were not overweight or obese, baseline leptin was able to predict response to treatment at 6 and 12 months.

CONCLUSIONS

In the short term, baseline leptin levels predict disease activity in all RA patients and response to treatment in RA patients with normal weight.
