One example of ixekizumab-induced ISRs on the patient’s abdomen during the initial injection, with a total of two injections of 80 mg/pen, one administered on each side. Subsequently, no further ISRs occurred following his twelfth injection.
Progression of ISRs on the right upper arm (yellow arrows) over a period of 3 consecutive days following ixekizumab administration. (a) day 1. (b) day 2. (c) day 3. The patient has experienced ixekizumab-induced ISRs consistently from the first injection up to the present, including the most recent seventeenth injection.
Events of special interests from ixekizumab treatment.
Univariate analysis of factors associated with ixekizumab-induced injection site reactions.

Ixekizumab (Taltz®) is a humanized anti-IL-17A monoclonal antibody approved for the treatment of various inflammatory diseases including psoriasis and psoriatic arthritis. Despite the favorable efficacy and safety, ixekizumab is also known for its high incidence of injection site reactions (ISRs), ranging from 6% to 55% in different studies according to different definitions and studied population. However, specific risk factors for ixekizumab-induced injection site reactions in patients with psoriatic diseases had not been well studied. In this retrospective study, we found that overweight or obesity might be a protective predictor for the occurrence of ixekizumab-induced ISRs in patients with psoriatic disease. Meanwhile, having a positive family history of psoriasis might be a potential risk factor. Last but not least, patients with diarrhea following ixekizumab injection were associated with a higher risk of developing ISRs. Future high-quality studies with larger samples are warranted to verify the relationship.

... As regards possible predictive factors for ISR development, heavier body weight seems to be a protective factor, as reported in literature, probably due to differences in subcutaneous fat thickness between normal-weight and obese patients. On the contrary, having a family history of psoriasis could be a possible risk factor [105]. Of interest, patients with diarrhea following ixekizumab injection seem to be associated with a higher risk of developing ISRs [105]. ...
