Abstract
PURPOSE OF REVIEW Treatment of Inflammatory Bowel Diseases (IBD) is challenging; thus, the need for newer therapeutic options with an oral route of administration has led to the development of novel small molecules drugs (SMDs). We aim to highlight the most common Adverse events (AEs) associated with SMDs and recommendations on monitoring for AEs before and during treatment. RECENT FINDINGS SMDs, such as Tofacitinib, a JAK inhibitor, have been associated with laboratory abnormalities, infections, and risk of thromboembolic events. Therefore, oral agents with greater selectivity in JAK inhibition, such as tofacitinib and upadacitinib, were later developed. Ozanimod and etrasimod, S1PR agonists, require closer safety profile monitoring by clinicians. Multiple therapies have been recently developed with variable efficacy. However, they have been associated with AEs, and some require close monitoring prior to and during therapy. Clinicians should highlight these adverse events to patients while reassuring the safety profile of these novel SMDs for IBD is favorable.

Abstract
Vitiligo is a common, autoimmune, depigmenting disorder of the skin. Janus Kinase inhibitors have emerged as promising topical and oral therapeutic options for vitiligo. There have been no reports of vitiligo being treated with oral Abrocitinib, a selective Janus Kinase 1 inhibitor approved for the treatment of moderate to severe atopic dermatitis. Here, we present a 61-year-old male with acrofacial vitiligo who had repigmentation plateau with twice daily tacrolimus 0.1% ointment, oral ginkgo biloba, and oral minipulse prednisone × 4 months; however, they had significant improvement after taking abrocitinib 100 mg per day for 2 months. He was able to transition topical tacrolimus twice weekly monotherapy for maintenance. This report shows that oral Janus Kinase inhibitors may be a useful option for the treatment of recalcitrant vitiligo. Results of ongoing randomized control trials are needed to determine the durability and safety of oral Janus Kinase inhibitors long-term.

Abstract
This point of view explores the safety concerns of Janus kinase inhibitors (JAK-Is), used in treating rheumatoid arthritis (RA) and other rheumatologic conditions. Increasing evidence shows that JAK-Is may elevate the risk of venous thromboembolism (VTE), especially pulmonary embolism. This fact has prompted the European Medicines Agency to advise cautious use of these drugs in patients over 65, smokers, and those at risk of cardiovascular issues or cancer. The paper analyses the evidence on the association between VTE risk and RA and whether different JAK-Is pose different risks. It also probes the link between VTE, lipids, and JAK inhibition, noting that JAK-Is can alter HDL and LDL levels. On the other hand, some evidence indicates that tighter LDL-cholesterol control could mitigate VTE risk, particularly pulmonary embolism. Moreover, data from trials show little attention to treating this main cardiovascular and VTE risk factor in rheumatological patients. Although the lipid paradox theory emphasizes the U-shaped relationship between LDL cholesterol and cardiovascular risk in patients with RA, uncontrolled levels of clinically relevant LDL cholesterol remain closely linked to cardiovascular and VTE risk. In conclusion, high-potency statins could help to manage the increased cardiovascular and VTE risk concomitant to JAK-Is treatment in rheumatologic patients without depriving them of the best therapeutic choice and, in addition, reducing the inherent risk associated with the disease.

Abstract
OBJECTIVE Patients with rheumatoid arthritis (RA) treated with Janus Kinase inhibitors (JAKi) are at increased risk of Herpes Zoster (HZ). The objective of this study was to investigate serological immunogenicity and safety of the HZ subunit (HZ/su) vaccine in RA patients treated with JAKi, for which little is known. METHODS RA patients treated with JAKi (n = 82) at the Department of Rheumatology, Skåne University Hospital, Sweden, and healthy controls (n = 51) received two doses of the HZ/su vaccine (Shingrix). Vaccine-specific antibody responses were analysed using indirect enzyme-linked immunosorbent assay (ELISA). Post-vaccination antibody levels were compared between patients and controls using analysis of covariance. Potential predictors for vaccine response were investigated using a multivariable linear regression analysis. Self-reported adverse events (AEs) and changes in RA disease activity were analysed. RESULTS Following vaccination, vaccine-specific antibody levels increased significantly in both patients and controls (p< 0.0001). 80.5% of patients and 98.0% of controls achieved a ≥ 4-fold increase in antibody levels. Post-vaccination antibody levels were lower in patients than controls (ratio 0.44, 95% CI 0.31-0.63), and lower in patients receiving JAKi+Methotrexate than JAKi monotherapy (ratio 0.43, 95% CI 0.24-0.79). AEs, mostly mild/moderate, were common. One patient developed HZ and six patients (6.5%) had increased RA disease activity following vaccination. CONCLUSION The HZ/su vaccine was serologically immunogenic in most RA patients treated with JAKi. Moreover, the vaccine had an acceptable safety profile. These results support recommendations for usage of the HZ/su vaccine in this vulnerable population. TRIAL REGISTRATION ClinicalTrials.gov, https://clinicaltrials.gov, NCT03886038.

Abstract
INTRODUCTION Biological disease-modifying anti-rheumatic drugs (bDMARDs) targeting interleukin (IL)-6 and IL-1β represent a steroid-sparing first-line therapy used in systemic-onset juvenile idiopathic arthritis (sJIA). Recently, the occurrence of pulmonary alveolar proteinosis (PAP) in sJIA patients was reported with early-onset and exposure to bDMARDs as potential risk factors. We report on a new case with longitudinal immunomonitoring successfully treated by Janus Kinase inhibitors (JAKi) and review past clinical descriptions of this new entity. METHODS We report one case of pulmonary alveolar proteinosis and macrophage activation syndrome (PAP-MAS) with longitudinal immunomonitoring. We then conducted a review of the literature of seven publications reporting 107 cases of PAP-MAS sJIA, and included the main characteristics and evolution under treatment. RESULTS Of the seven articles analyzed, the incidence of PAP-MAS among sJIA patients varied from 1.28% to 12.9%. We report here a single case among a cohort of 537 sJIA patients followed in the pediatric department of the Hospices Civils de Lyon over the last 15 years. This child presented with all clinical and immunological characteristics of PAP-MAS. After several lines of treatment, he benefited from JAKi and improved with respect to both systemic symptoms and lung disease. In the literature, strategies with monoclonal antibodies targeting either INF-γ or IL-1β/IL-18 have been tested with variable results. Orally taken JAKi presents the advantage of targeting multiple cytokines and avoiding parenteral injections of monoclonal antibodies that may contribute to the pathogenesis. CONCLUSIONS JAKi represent a promising option in the treatment of lung disease associated with sJIA.

Abstract
Many epidemiological studies have shown an increased risk of venous thromboembolism (VTE) in patients with rheumatoid arthritis (RA). RA and VTE share some background factors, such as increasing age, smoking, and obesity. At the same time, other VTE factors, such as knee replacement and oral contraceptive pills, occur commonly in RA patients. In addition, the chronic inflammatory state of RA might hypothetically lead to endothelial injury and a hypercoagulable state. Two critical pathophysiological pathways lead to VTE. Recently, concerns increased about the increased risk of VTE in patients using Janus Kinase inhibitors. This review aims at reviewing the risk of VTE in RA and the role of traditional risk factors and disease-related inflammation and develops a conceptual framework that describes the interaction between these factors.

Abstract
OBJECTIVES Excessive and inappropriate production of pro-inflammatory cytokines plays a key role in Still's disease. JAK inhibitor (JAKi) agents mainly block pro-inflammatory cytokine pathways, notably IL-6 and IFN. The objective was to assess the efficacy and safety of JAKi agents in difficult-to-treat systemic juvenile idiopathic arthritis (SJIA) or adult-onset Still's disease (AOSD). METHODS This retrospective study was based on a national survey conducted in the departments of rheumatology, paediatric rheumatology and internal medicine of French hospitals regarding SJIA and AOSD patients who received JAKi agents. The data were collected with a standardised questionnaire and analysed at different times (treatment initiation, months 1, 3, and 6 and the end of follow-up). RESULTS Nine patients (7 adults) were included. All patients showed inadequate response to corticosteroids or conventional synthetic or biologic disease-modifying anti-rheumatic drugs. Baricitinib was used in 5 patients, ruxolitinib in 2, tofacitinib in 2, and upadacitinib in 1. A JAKi was used combined with corticosteroids in all but 2 patients. A JAKi was associated with anakinra and corticosteroids in one patient, and with methotrexate, anakinra and corticosteroids in another. The median follow-up was 16 [1-33] months. Two cases out 9 showed complete remission, 3/9 partial response and 4/9 treatment failure. At the last visit, corticosteroids could be decreased but not stopped. Tolerance of the JAKi was acceptable (no severe adverse events). CONCLUSION JAKi agents may be a therapeutic option for some patients with difficult-to-treat Still's disease, especially those with partial response to medium- or high-dose corticosteroids or biologics.

Abstract
BACKGROUND Rett syndrome (RTT) is a neurodevelopmental disorder caused by mutations in the X-linked methyl-CpG binding protein 2 (MeCP2) gene. While MeCP2 mutations are lethal in most males, females survive birth but show severe neurological defects. Because X-chromosome inactivation (XCI) is a random process, approximately 50% of the cells silence the wild-type (WT) copy of the MeCP2 gene. Thus, reactivating the silent WT copy of MeCP2 could provide therapeutic intervention for RTT. METHODS Toward this goal, we screened ~ 28,000 small-molecule compounds from several libraries using a MeCP2-luciferase reporter cell line and cortical neurons from a MeCP2-EGFP mouse model. We used gain/increase of luminescence or fluorescence as a readout of MeCP2 reactivation and tested the efficacy of these drugs under different drug regimens, conditions, and cellular contexts. RESULTS We identified inhibitors of the JAK/STAT pathway as XCI-reactivating agents, both by in vitro and ex vivo assays. In particular, we show that AG-490, a Janus Kinase 2 (JAK2) kinase inhibitor, and Jaki, a pan JAK/STAT inhibitor, are capable of reactivating MeCP2 from the inactive X chromosome, in different cellular contexts. CONCLUSIONS Our results suggest that inhibition of the JAK/STAT pathway is a new potential pathway to reinstate MeCP2 gene expression as an efficient RTT treatment.

INTRODUCTION Inflammatory bowel diseases (IBDs) are immune-mediated chronic inflammatory disorders of the gastrointestinal tract whose pathogenesis is not yet fully understood. Despite the advent of biological agents, there are still unmet needs for IBD patients, due to suboptimal rate of sustained remission achieved. Small molecule drugs (SMDs), the next generation of selective drugs in IBD, show promising results in ongoing trials. AREAS COVERED We describe the pharmacodynamics and pharmacokinetic features of novel SMDs and their main differences with biologic agents. EXPERT OPINION Small molecule drugs are a promising class of drugs for the treatment of ulcerative colitis and Crohn's disease with good results in inducing and maintaining remission. Hence, over the next few years physicians will have numerous options of small molecule drugs for the treatment of patients with IBD. This group of drugs are potentially easier to use over biological agents due to pharmacokinetic features such as oral administration, short half-life, high volume of distribution, and lack of immunogenicity. On the other hand, drug-drug interactions can happen with small-molecule drugs, principally due to competitive metabolic and clearance mechanisms.
