Large-vessel vasculitides (LVVs) include giant cell arteritis (GCA) and Takayasu's arteritis (TAK). Even if similar, these two entities differ in terms of treatment and outcomes. High doses of glucocorticoids (GCs) are still the first choice for the treatment of both conditions. However, adjunctive therapies are recommended in selected patients in order to decrease the risk of relapse and the amount of side effects related to GCs. Tumour necrosis factor α inhibitors (TNFis) and tocilizumab (TCZ) are used for the treatment of LVVs, with some differences. In GCA, TCZ has been proved to be effective and safe in inducing remission with some open questions still remaining, whereas data about TNFis are scarce and nonconclusive. On the contrary, in TAK either TNFis or TCZ seem to be able to control symptoms and angiographic progression in refractory forms. However, their place in the management of treatment must still be clarified, and as a result the American College of Rheumatology and EULAR guidelines slightly differ in the recommendations about when and what treatment to start. Thus, the aim of this review is to look at the evidence on the use of TNFis and TCZ in LVVs, outlining the pros and cons of both therapies.
