Abstract
BACKGROUND The advent of biosimilars may increase the frequency of dose escalation with biologics in psoriasis. OBJECTIVE To explore the frequency and outcomes of dose escalation with adalimumab etanercept, and ustekinumab. METHODS Data were extracted from DermaReg-Pso, a psoriasis register in Stockholm, Sweden. The main exposure was treatment, and the main outcome was dose escalation. We describe outcomes with dose escalation by estimating drug survival and changes in the Psoriasis Area and Severity Index (PASI). RESULTS 554 patients had 946 treatment episodes with adalimumab, etanercept, or ustekinumab. The cumulative incidence of dose escalation was 4.1 per 100 treatment years. The Hazard Ratios (HRs) for dose escalation with ustekinumab vs adalimumab and ustekinumab vs etanercept were 1.93 (95% CI: 1.25-2.98), and 2.20 (95% CI: 1.42-3.41), respectively. After dose escalation, the HRs for treatment discontinuation with adalimumab and etanercept compared with ustekinumab were 3.10 (95% CI: 1.56-6.18) and 7.15 (95% CI: 3.96-12.94), respectively. PASI was higher after compared to before dose escalation for etanercept (p = 0.036), but not for adalimumab (p = 0.832) or ustekinumab (p = 0.300). CONCLUSIONS Dose escalation was comparatively more frequent with ustekinumab than with adalimumab or etanercept; however, treatment discontinuation after dose escalation was more common with adalimumab and etanercept than ustekinumab.

Abstract
Hyperactivated Janus kinase (JAK) signaling is an appreciated drug target in human cancers. Numerous mutant JAK molecules as well as inherent and acquired drug resistance mechanisms limit the efficacy of JAK inhibitors (JAKi). There is accumulating evidence that epigenetic mechanisms control JAK-dependent signaling cascades. Like JAKs, epigenetic modifiers of the histone deacetylase (HDAC) family regulate the growth and development of cells and are often dysregulated in cancer cells. The notion that inhibitors of histone deacetylases (HDACi) abrogate oncogenic JAK-dependent signaling cascades illustrates an intricate crosstalk between JAKs and HDACs. Here, we summarize how structurally divergent, broad-acting as well as isoenzyme-specific HDACi, hybrid fusion pharmacophores containing JAKi and HDACi, and proteolysis targeting chimeras for JAKs inactivate the four JAK proteins JAK1, JAK2, JAK3, and tyrosine kinase-2. These agents suppress aberrant JAK activity through specific transcription-dependent processes and mechanisms that alter the phosphorylation and stability of JAKs. Pharmacological inhibition of HDACs abrogates allosteric activation of JAKs, overcomes limitations of ATP-competitive type 1 and type 2 JAKi, and interacts favorably with JAKi. Since such findings were collected in cultured cells, experimental animals, and cancer patients, we condense preclinical and translational relevance. We also discuss how future research on acetylation-dependent mechanisms that regulate JAKs might allow the rational design of improved treatments for cancer patients. SIGNIFICANCE STATEMENT: Reversible lysine-ɛ-N acetylation and deacetylation cycles control phosphorylation-dependent Janus kinase-signal transducer and activator of transcription signaling. The intricate crosstalk between these fundamental molecular mechanisms provides opportunities for pharmacological intervention strategies with modern small molecule inhibitors. This could help patients suffering from cancer.

Real-world experience and long-term evaluation of tofacitinib in refractory alopecia areata: A prospective, open-label, single-center study in Asian Arab population. Dermatol Ther 2022; 35:e15871. [PMID: 36177791 DOI: 10.1111/dth.15871] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 07/21/2022] [Accepted: 09/26/2022] [Indexed: 11/30/2022]
Abstract
Tofacitinib is a pan-janus kinase inhibitor (JAK) which has been tested off-label in alopecia areata (AA) with promising results. However, evidence of tofacitinib in real-life setting is still poor. We evaluated long-term efficacy and safety of tofacitinib for refractory AA. This is a prospective, open-label, observational, single-center cohort study conducted between January 2018 and December 2020. Primary end-point was the percent change in Severity of Alopecia Tool (SALT) at the basal visit and at the most recent follow-up visit. Three categories of treatment response were analyzed. Data on 47 participants of Arab-Asian heritage were analyzed. A complete and partial regrowth was observed in 18 patients (41.86%) and 11 patients (25.58%), respectively. In 12 patients (27.9%), no response was obtained. Most of the non-responders belonged to the alopecia universalis group (66.67%). No statistical differences were observed in rates of regrowth between pediatric and adult individuals (p = 0.52), nor between women and men. Significant differences in the average duration of tofacitinib treatment were obtained among the three categories of regrowth (p < 0.003), notably duration of AA did not impact the clinical regrowth (p = 0.62). To the best of our knowledge, this is the first prospective, observational, long-term study using tofacitinib in refractory AA. Rates of regrowth and side effects are analogous to previous works. Length of tofacinitib therapy should last for 12 months before considering any discontinuation or change, since early cessation can lead to treatment failures or incomplete regrowth. Maintenance therapy after complete regrowth has demonstrated to be safe and effective to prevent recurrences of hair loss.

Abstract
BACKGROUND Corticosteroids are a mainstay of the treatment of moderately severe relapses of ulcerative colitis, yet almost 50% of patients do not respond fully to these and risk prolonged steroid use and side effects. There is a lack of clarity about the definitions of steroid resistance, the optimum choice of treatment, and patient and health-care professional treatment preferences. OBJECTIVES The overall aim of this research was to understand how steroid-resistant ulcerative colitis is managed in adult secondary care and how current practice compares with patient and health-care professional preferences. DESIGN A mixed-methods study, including an online survey, qualitative interviews and discrete choice experiments. SETTING NHS inflammatory bowel disease services in the UK. PARTICIPANTS Adults with ulcerative colitis and health-care professionals treating inflammatory bowel disease. RESULTS We carried out a survey of health-care professionals (n = 168), qualitative interviews with health-care professionals (n = 20) and patients (n = 33), discrete choice experiments with health-care professionals (n = 116) and patients (n = 115), and a multistakeholder workshop (n = 9). The interviews with and survey of health-care professionals showed that most health-care professionals define steroid resistance as an incomplete response to 40 mg per day of prednisolone after 2 weeks. The survey also found that anti-tumour necrosis factor drugs (particularly infliximab) are the most frequently offered drugs across most steroid-resistant (and steroid-dependent) patient scenarios, but they are less frequently offered to thiopurine-naive patients. Patient interviews identified several factors influencing their treatment choices, including effectiveness of treatment, recommendations from health-care professionals, route of administration and side effects. Over time, depending on the severity and duration of symptoms and, crucially, as medical treatment options become exhausted, patients are willing to try alternative treatments and, eventually, to undergo surgery. The discrete choice experiments found that the probability of remission and of side effects strongly influences the treatment choices of both patients and health-care professionals. Patients are less likely to choose a treatment that takes longer to improve symptoms. Health-care professionals are willing to make difficult compromises by tolerating greater safety risks in exchange for therapeutic benefits. The treatments ranked most positively by patients were infliximab and tofacitinib (each preferred by 38% of patients), and the predicted probability of uptake by health-care professionals was greatest for infliximab (62%). LIMITATIONS The survey and the discrete choice experiments with patients and health-care professionals are limited by their relatively small sample sizes. The qualitative studies are subject to selection bias. The timing of the different substudies, both before and during the COVID-19 pandemic, is a potential limitation. CONCLUSIONS We have identified factors influencing treatment decisions for steroid-resistant ulcerative colitis and the characteristics to consider when choosing treatments to evaluate in future randomised controlled trials. The findings may be used to improve discussions between patients and health-care professionals when they review treatment options for steroid-resistant ulcerative colitis. FUTURE WORK This research highlights the need for consensus work to establish an agreed definition of steroid resistance in ulcerative colitis and a greater understanding of the optimal use of tofacitinib and surgery for this patient group. A randomised controlled trial comparing infliximab with tofacitinib is also recommended.

Abstract
BACKGROUND Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). The induction dose is 10 mg twice daily (b.d.), whilst for maintenance therapy, the lowest effective dose should be used. AIM To examine published evidence on the two tofacitinib dosing strategies used in UC treatment, including expert interpretation of the data and how they could inform clinical practice. METHODS The use of tofacitinib 5 or 10 mg b.d. was assessed using data from the tofacitinib UC clinical programme in the context of different clinical scenarios. We include experts' opinions on the clinical implications of dose adjustment to inform the benefit/risk of using tofacitinib 5 or 10 mg b.d., based on clinical scenarios and real-world data. RESULTS Factors to consider when adjusting the tofacitinib dose include disease severity, comorbidities and previous biological exposure. The endoscopic subscore can determine whether a patient is a good candidate for dose reduction. Following disease relapse, the response can be recaptured in a substantial number of patients with a dose increase. Furthermore, data are now published showing real-world use of tofacitinib and, so far, these are consistent with data from the clinical trials. CONCLUSION Clinicians must consider the benefit/risk balance of tofacitinib 10 versus 5 mg b.d. in terms of dose-related side effects, as well as the safety implications of undertreating active disease. All patients should be closely monitored for disease relapse following dose reduction or interruption for early recapture of response.

Abstract
INTRODUCTION Tofacitinib has emerged as a useful drug for the treatment of ulcerative colitis (UC). AREAS COVERED There is an unmet need for cost-effective, non-immunogenic drugs with a safe adverse effect profile to treat patients with ulcerative colitis. In the present review, we evaluate the available literature to inform the appropriate positioning of tofacitinib in the current drug landscape and identify subsets where its use should be done with caution. EXPERT OPINION Tofacitinib is helpful in the treatment of patients where the standard conventional or biological therapies have failed or were not tolerated. With lower costs of the generic drug than the biologicals (or biosimilars), it could be an important therapy in low- to middle-income countries. The risk of infections, especially Herpes Zoster and tuberculosis, needs to be addressed before initiation. Tofacitinib should be avoided in patients with venous thromboembolism and cardiovascular disease risk factors. Due to limited evidence, the use is not recommended in pregnancy, while it should be used with caution in elderly citizens. Future trials should look into the head-to-head comparison of tofacitinib with biologicals. The role of tofacitinib in acute severe colitis needs evaluation with comparative trials with current standards of care.

Abstract
Despite great advances in the diagnosis and treatment of immunoinflammatory rheumatic diseases, which have led to a significant improvement in the prognosis in many patients, the fundamental medical problems of this pathology the restoration of the quality of life and the reduction of mortality to the population level are far from being resolved. This served as a stimulus for the study of new approaches to the pharmacotherapy of IVRD, one of which is associated with the use of low molecular weight chemically synthesized drugs that inhibit intracellular "signaling" molecules Janus kinase. Modern advances regarding the use of Janus kinase inhibitors in the treatment of immunoinflammatory rheumatic diseases and COVID -19 are considered.
