The clinical relevance of creatinine phosphokinase elevations is also uncertain, but it may be relevant to measure the level this enzyme before and some weeks after initiation of treatment, says Dr. Tore Kvien, a professor emeritus and senior researcher at the University of Oslo and the department of rheumatology at Diakonhjemmet Hospital, Oslo, Norway.
“Overall, upadacitinib represents an important treatment alternative for patients with RA, but patients and clinicians should be aware of potential adverse events and take this into account when prescribing upadacitinib and monitoring patients during follow-up,” Dr. Kvien, who wasn’t involved in the study, says by email.
