The selective JAK1 inhibitor upadacitinib restores impaired neutrophil chemotaxis in the proplatelet formation of immune thrombocytopenia
(ASH 2025)
- "In vivo studies showed that upadacitinibcould rescue the impaired PPF in both patients and mice model with ITP.ConclusionsThe BM of ITP patients displayed impaired neutrophil chemotaxis regulated by type I interferon pathway.Upadacitinib restores neutrophil chemotaxis and corrected impaired PPF by inhibiting type I interferonpathway and upregulating CXCR4. It sheds light on a novel mechanism of ITP pathogenesis and providesa basis for the therapeutic potential of upadacitinib in ITP patients."

Trial information materials were adapted to better reflect the potential overlap in risk factors identified by this meta-analysis, and a reduced dosing strategy was introduced for participants with relevant cardiovascular disease risk factors. The findings of this trial will better inform future treatment decision making for people with PPP."

Tralokinumab and lebrikizumab were excluded as all patients had prior dupilumab...Factors favouring dupilumab prescribing include older age, asthma status and cardiovascular risk factors. Factors favouring JAKi prescribing included speed of onset, ease of prescribing, younger age and needle phobia."

(PubMed, Br J Dermatol)
- "For eczema, therapies such as dupilumab show limited evidence in also treating AA...For instance, baricitinib is licensed for both AD and AA, while upadacitinib is licensed for AD and is currently in phase III trials for AA. Amlitelimab, which targets the OX40 ligand pathway, is currently in phase III clinical trials for atopic dermatitis and in phase II trials for severe AA...In psoriasis, overlapping therapies include ustekinumab, approved for psoriasis and being studied for AA. As for patients with RA, tofacitinib is approved for moderate-to-severe disease and is also utilized in AA.

To our knowledge, this is the first retrospective case series to report tralokinumab-associated inflammatory arthritis.

However, JAK inhibitors can safely be restarted after resolution of anaemia, which is important information in management of this complication and providing patient care."

(PubMed, Br J Dermatol)
- "He had tried superpotent topical corticosteroids and oral prednisolone, as well as emollients, none of which had improved his symptoms...Tralokinumab was trialled for 12 weeks, as this has a single therapeutic target (interleukin-13), but unfortunately there was no improvement. Following discussion with the immunologists, he was commenced on upadacitinib as this was felt to have a more targeted immunosuppressive effect above agents such as methotrexate and dupilumab. We await his next follow-up appointment to assess response. This case highlights the complexity of treating an immunocompromised individual with immunosuppressive agents, when the cause of their immunosuppression is unknown."

P114 Efficacy and safety of oral Janus kinase, tyrosine kinase 2 and phosphodiesterase 4 inhibitors in the treatment of chronic plaque psoriasis: a network meta-analysis.
(PubMed, Br J Dermatol)
- "After 16-24 weeks of treatment, tofacitinib and deucravacitinib had the highest efficacy, followed by apremilast, orismilast, upadacitinib and brepocitinib. Zasocitinib, a new highly selective allosteric TYK2 inhibitor, has recently demonstrated promising efficacy in the treatment of psoriasis, with 33% of patients achieving PASI 100 (complete clearance of psoriasis lesions) after just 12 weeks of treatment. In conclusion, oral TYK2 inhibitors have shown efficacy in the treatment of chronic plaque psoriasis comparable with adalimumab, with newer agents demonstrating enhanced effectiveness and surpassing PDE-4 inhibitors in therapeutic outcomes. JAK inhibitors, particularly tofacitinib, exhibit comparable efficacy to some TYK2 and PDE-4 inhibitors."

Findings should be interpreted cautiously given the limitations of spontaneous reporting systems and the exploratory nature of the analysis. Further studies are needed to better characterize the JAKI safety in pregnancy."

Prepuberty Exposure to Polystyrene Nanoplastics Induces Cardiac Inflammation Through Calcium Overload-Mediated ROS/JAK1/STAT3 Signaling Cascade.
(PubMed, Free Radic Biol Med)
- "Treatment of HL-1 cells with N-Acetylcysteine (NAC) normalized the activity of the JAK1/STAT3 pathway and the levels of inflammatory cytokines. Furthermore, either inhibition of JAK1 with upadacitinib or knockdown of STAT3 in PS-NP-exposed HL-1 cells led to proinflammatory cytokine levels comparable to those in control cells...Notably, pharmacological inhibition of calcium flux attenuated PS-NP-induced mitochondrial dysfunction, oxidative stress, and inflammatory responses in HL-1 cardiomyocytes. Collectively, our findings indicate that prepubertal PS-NP exposure triggers cardiac inflammation, which is likely mediated by MAM-dependent mitochondrial calcium overload and subsequent activation of the ROS/JAK1/STAT3 signaling axis."

Preventive Effectiveness of Recombinant Zoster Vaccine in Rheumatoid Arthritis Patients Treated with Janus Kinase Inhibitors.

- "HZ incidence varied by JAK inhibitor: baricitinib (5.5 vs 9.9), upadacitinib (12.4 vs 6.2), and filgotinib (0.0 vs 1.6) per 100 person-years. Conclusion Although not statistically significant, RZV vaccination tended to reduce the incidence of HZ in Japanese RA patients receiving JAK inhibitors. The effectiveness varied according to the type of JAK inhibitor, with lower lymphocyte counts and higher disease activity, and it may predict insufficient protection."

Targeting the JAK/STAT pathway in palmoplantar pustulosis: a review.

- "Recent clinical case reports and early studies have shown favourable outcomes with JAK inhibitors, such as tofacitinib, upadacitinib, baricitinib, deucravacitinib and abrocitinib, in refractory PPP cases. JAK inhibitors emerge as a promising therapeutic strategy for PPP, due to their ability to block multiple inflammatory pathways simultaneously, especially where other cytokine-targeted therapies have failed. However, despite compelling early reports, larger controlled trials are essential to establish definitive efficacy, clarify long-term safety and optimize clinical use."

Interleukin-6 Inhibitor-Induced Leukocytoclastic Vasculitis: A Case Report With a Literature Review.
(PubMed, Case Reports Immunol)
- "Her rheumatoid arthritis had been managed with upadacitinib for several years, which was discontinued due to persistent transaminitis...The rash resolved slowly in a month after discontinuation of tocilizumab and prescription of prednisone 20 mg daily. At her 3-month follow-up, the patient remained in remission, and her rheumatoid arthritis was uneventfully managed with abatacept. While most cases of biologic-associated LCV are induced by TNF-α inhibitors, only two known cases of tocilizumab-induced hypersensitivity vasculitis have been published in the literature. Our case represents only the third reported instance in the literature, highlighting the need to raise awareness of tocilizumab as a potential cause of leukocytoclastic vasculitis and the importance of prompt recognition and management."
