Bejerano C, Blanco R, González-Vela C, et al. Refractory polymyalgia rheumatica as presenting manifestation of large-vessel vasculitis associated to sarcoidosis. Successful response to adalimumab. Clin Exp Rheumatol. 30:(1 Suppl. 70):S94-S97
Sarcoidosis may present with musculoskeletal features or mimic rheumatic diseases. We report on a patient who had been initially diagnosed as having polymyalgia rheumatica. Because of refractory disease associated to atypical features such as severe inflammatory low back pain, dull and achy pain in the thighs, claudication of the lower limbs and bad response to corticosteroids and methotrexate (MTX), an 18F-fluorodeoxyglucosepositron emission tomography with CT (FDG PET/CT) was performed. This technique disclosed data suggestive of arteritis of large vessels involving the ascending, arch and descending aorta as well as high FDG uptake in the femoral and posterior tibial arteries of both lower extremities. Also, increased FDG uptake was observed in the right paratracheal, retrotracheal, subcarinal, gastrohepatic ligament, coeliac and right renal hilar lymph nodes. Four lymph nodes, taken during mediastinoscopy, confirmed a diagnosis of sarcoidosis. Treatment with adalimumab (40 mg every 2 weeks subcutaneously) along with prednisone and MTX was initiated yielding progressive improvement of symptoms and normalisation of laboratory abnormalities. Five months after the onset of adalimumab a new FDG PET/CT showed complete absence of uptake of lymph nodes as well as decrease of vascular FDG uptake. To our knowledge, this is the first patient treated with adalimumab because of a large-vessel vasculitis in the setting of sarcoidosis refractory to conventional therapy. This case reinforces the claim that sarcoidosis should be considered a diagnostic challenge in the assessment of patients presenting with inflammatory musculoskeletal symptoms.

- "In another study, a case has been reported of a patient who had been initially diagnosed as having PMR. Because of refractory disease, treatment with ADA (40 mg every 2 weeks subcutaneously) along with prednisone and methotrexate (MTX) was initiated, yielding progressive improvement of symptoms and normalization of laboratory abnormalities.8 "

ABSTRACT: Vasculitis syndromes are relative rare conditions but can cause significant mortality and morbidity if not treated adequately. Recent advances in immunosuppressant therapy have radically changed the course of these diseases. However, the standard therapy is not always well tolerated by patients, and some cases are refractory to treatment. New therapeutic possibilities have emerged with the use of so-called "biologics," a new class of genetically engineered drugs used for inflammatory rheumatic diseases, including rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis. In the present review, summarized are the most recent data on the efficacy and safety of biologics in the treatment of vasculitis syndromes that cannot be treated with standard therapy.

ABSTRACT: Glucocorticoids are the mainstay of treatment of idiopathic retroperitoneal fibrosis (IRF). However, relapses are frequent upon tapering of the glucocorticoid dose. A variety of traditional immunosuppressants have been proposed as steroid-sparing agents, but some patients fail to adequately respond to combined glucocorticoid and immunosuppressive therapy. We report a patient with IRF refractory to combined glucocorticoid and methotrexate therapy treated with the anti-TNF-α monoclonal antibody infliximab. Infliximab was administered at 5 mg/kg/bodyweight at week 0, 2, 6 and 8-weekly thereafter for 3 consecutive years. Drug efficacy and safety were assessed clinically and by laboratory tests at treatment onset and subsequently before each infusion. In addition, 18FFluorodeoxyglucose (FDG) positron emission computerised tomography (PET/CT) and abdominal CT scans were used to monitor disease activity and response to treatment. Infliximab therapy resulted in a satisfactory clinical and laboratory response paralleled by an improvement in imaging findings. No serious adverse events were noted. Infliximab may be an effective and safe treatment for refractory IRF. A controlled study is required to confirm our findings.
