The study objective is aimed to describe all country, site, investigator and patient variables that lead to treatment persistence for at least 12 months among patients with rheumatologic and intestinal chronic inflammatory diseases who were switched to FK adalimumab, in order to develop a model to predict persistence at 12 months.

Inclusion Criteria:

6. Patients willing to sign informed consent to meet data protection requirements

Exclusion Criteria:

1. Unwillingness to provide written informed consent.
2. Patients participating or expected to participate in any randomised clinical trial during their treatment with FK adalimumab.
