Registry-based observational study of patients with rheumatoid arthritis
treated with baricitinib or tofacitinib in a tertiary hospital
Abstract
The aim of the study was to describe the use of two Janus kinase
inhibitors (JAKi) in patients with rheumatoid arthritis (RA) recorded at
Vall d’Hebron University Hospital (VHUH) between September 2017-November
2019. The data was extracted from the register of Patients and
Treatments and medical records. Out of the thirty-nine patients included
90.0% were women, median age 56 years (IQR 29-72) and disease duration
15 years (IQR 8-20). Tofacitinib was the most used (28 patients). All
patients had been previously treated with conventional synthetic disease
modifying antirheumatic drugs (csDMARDs), and 79.5% with at least one
biological DMARD (bDMARD). In 16 patients (41.0%) disease activity
category improved. Treatment was withdrawn in 9 patients, mainly due to
lack of efficacy (5). Five patients treated with tofacitinib reported
gastrointestinal and/or skin disorders. This study shows the usefulness
of registries of treated patients to study the use of the new and
expensive drugs.
