Patient adherence with a smartphone app for patient-reported outcomes in rheumatoid arthritis.

Objectives: Electronic patient-reported outcomes (ePROs) transmitted digitally allow patients to communicate with their clinicians and track the activity of chronic diseases, such as RA. Several ePRO smartphone apps have been developed in rheumatology, yet few data have been reported regarding patient adherence. We developed a PRO app for RA and assessed adherence over 6 months.

Adverse Effects of Low-Dose Methotrexate: A Randomized Trial.

Background: Low-dose methotrexate (LD-MTX) is the most commonly used drug for systemic rheumatic diseases worldwide and is the recommended first-line agent for rheumatoid arthritis. Despite extensive clinical use for more than 30 years, few data on adverse event (AE) rates derive from randomized, placebo-controlled trials, where both causality and magnitude of risk can be inferred.

Objective: To investigate AE rates, risk, and risk differences comparing LD-MTX versus placebo.
