Clinical Case Summary
Tofacitinib has recently been introduced into European guidelines for managing moderate-severe Ulcerative Colitis (UC). Among the various extra-intestinal manifestations of UC is Hidradenitis Suppurativa (HS), also called acne inversa. Unfortunately, there is no evidence on the efficacy of tofacitinib in HS, such that recommendations generally suggest anti-tumour necrosis factors, antibiotics, anakinra, ustekinumab or surgery. We report the case of a 26-year-old Caucasian non-smoking, nonalcohol-drinking, and non-obese woman diagnosed with UC E3 (i.e., pancolitis) according to Montreal classification with Mayo endoscopic subscore (ESS) of 2 at the age of 23 years old. At the time, the patient underwent conventional therapy with oral prednisone at the immunosuppressive dosage combined with oral mesalazine. Following this therapy, she achieved clinical-biochemical remission. A year later, she developed a UC relapse associated with steroid dependence, also received another colonoscopy (E3, ESS=2, C-Reactive protein 18.6 mg/L) and received a dermatologic diagnosis of HS (mainly localized to axillary folds, inguinal folds, intermammary groove) and treated employing topical triamcinolone/neomycin cream. In addition, we introduced Adalimumab. She then experienced primary failure. Due to the persistence of moderate-severe symptoms and iron-deficiency anaemia, we introduced tofacitinib therapy in March 2022. At that moment, the patient had an HS relapse which the previous dermatologic treatment failed. Therefore, the patient undertook tofacitinib induction with 20 mg daily for eight weeks. Because of clinical improvement with the halving of discharges and absence of blood, however, complete clinical remission was not achieved. Therefore, it was decided to continue this regimen for another eight weeks. At the end of the 16 weeks, we noted UC clinical and biochemical remission and a marked amelioration of HS. Today, the patient continues a 10 mg daily tofacitinib regimen.
