Background: Tumour necrosis factor-alpha (TNF-α) plays a crucial role in sarcoidosis. In severe disease, treatment with TNF-α inhibitors may be effective. Objectives: Changes in sarcoid disease activity were assessed by fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET) in patients with recalcitrant sarcoidosis treated with adalimumab. Methods: Prospective 24-week observational study. Patients continued medication with steroids and antimetabolites and received adalimumab 40 mg subcutaneously every other week. Ten patients with biopsy-proven sarcoidosis (two men) were included with a median age of 47 years (range 35-73). An FDG-PET showing uptake indicating sarcoid activity was required at inclusion and repeated at the end of the study. FDG-PET uptake was assessed by calculated standardised uptake value (SUV). Blood samples and lung function tests were performed regularly. Quality of life was assessed by the short-form health survey (SF-36) questionnaire. Results: Following treatment with adalimumab, FDG-PET uptake decreased in nine patients ( P = 0.011) and increased in one patient. Maximum SUV fell from median 14.1 to 7.0 ( P < 0.03), and mean SUV fell from median 6.5 to 2.9 ( P < 0.02). Six patients had uptake in the lungs, which decreased after treatment ( P = 0.035). Six patients had uptake in the lymph nodes, which decreased after treatment in five patients ( P = 0.035). Four patients had non-lymphatic extrathoracic uptake, which decreased after treatment ( P = 0.05). There was no effect of adalimumab on pulmonary function tests, serum angiotensin I converting enzyme and blood lymphocyte (CD3+, CD4+, CD8+) concentrations. Physical component summary score (SF-36) increased during treatment, mental component summary score was unchanged. Conclusion: In sarcoidosis, treatment with adalimumab can reduce disease activity, as assessed by FDG-PET. Please cite this paper as: Milman N, Graudal N, Loft A, Mortensen J, Larsen J and Baslund B.
