Background Recently, based on the GiACTA trial results, weekly subcutaneous Tocilizumab (TCZ) has been approved for the treatment of Giant Cell Arteritis (GCA). It has showed to be effective and safety. Objectives Our aim was to compare the efficacy of TCZ according the route of administration. Methods Multicenter study of 134 GCA patients in treatment with TCZ. It was performed a comparative study between 2 groups according the route of administration of TCZ, intravenous (IV) or subcutaneous (SC). Results We study 134 patients divided in 2 groups: a) IV TCZ, 104 cases and, b) SC TCZ, 30 cases, with a mean age 73.4±8.2 years vs 71.9±10.6 years, respectively (p=0.501). Disease duration, clinical manifestations and acute phase reactants at TCZ onset were similar in both groups with non-statistical difference. 91.7% patients who received SC TCZ achieved prolonged remission after 12 months of treatment (p=0.043). And the glucocorticoid sparing effect of TCZ was greater in the same group, reaching a statistical difference at 3 and 24 months (p=0.017 and p=0.021). Patients under IV TCZ treatment suffered more adverse event during follow up (p=0.043). TABLE 1 and 2 summarizes the comparative study. Conclusion Patients in treatment with SC TCZ, reached prolonged remission after 12 months of treatment and were able to discontinue prednisone dose after 24 months of follow up. The incidence of adverse events was more frequent in the IV TCZ group, without difference in relation to infections.
