Influence of Safety Warnings on the Prescribing Attitude of JAK Inhibitors for Rheumatoid Arthritis in Italy.

Background/Objectives: The Janus kinase inhibitors (JAKi) tofacitinib (TOFA), baricitinib (BARI), upadacitinib (UPA), and filgotinib (FILGO) are effective drugs for the treatment of rheumatoid arthritis. However, the US Food and Drug Administration (FDA) raised concerns about the safety of TOFA after its approval. This prompted the European Medicines Agency (EMA) to issue two safety warnings for limiting TOFA use, then extended a third warning to all JAKi in patients at high risk of developing serious adverse effects (SAE). These include thrombosis, major adverse cardiac events (MACE), and cancer. The purpose of this work was to analyze how the first two safety warnings from the EMA affected the prescribing of JAKi by rheumatologists in Italy. Methods: All patients with rheumatoid arthritis who had been prescribed JAKi for the first time in a 36-month period from 1 July 2019, to 30 June 2022 were considered. Data were obtained from the medical records of 29 Italian tertiary referral rheumatology centers. Patients were divided into three groups of 4 months each, depending on whether the JAKi prescription had occurred before the EMA's first safety alert (1 July-31 October 2019, Group 1), between the first and second alerts (1 November 2019-29 February 2020, Group 2), or between the second and third alerts (1 March 2021-30 June 2021, Group 3). The percentages and absolute changes in the patients prescribed the individual JAKi were analyzed. Differences among the three groups of patients regarding demographic and clinical characteristics were also assessed. Results: A total of 864 patients were prescribed a JAKi during the entire period considered. Of these, 343 were identified in Group 1, 233 in Group 2, and 288 in Group 3. An absolute reduction of 32% was observed in the number of patients prescribed a JAKi between Group 1 and Group 2 and 16% between Group 1 and Group 3. In contrast, there was a 19% increase in the prescription of a JAKi in patients between Group 2 and Group 3. In the first group, BARI was the most prescribed drug (227 prescriptions, 66.2% of the total), followed by TOFA (115, 33.5%) and UPA (1, 0.3%). In the second group, the most prescribed JAKi was BARI (147, 63.1%), followed by TOFA (65, 27.9%) and UPA (33, 11.5%). In the third group, BARI was still the most prescribed JAKi (104 prescriptions, 36.1%), followed by UPA (89, 30.9%), FILGO (89, 21.5%), and TOFA (33, 11.5%). The number of patients prescribed TOFA decreased significantly between Group 1 and Group 2 and between Group 2 and Group 3 (p ˂ 0.01). The number of patients who were prescribed BARI decreased significantly between Group 1 and Group 2 and between Group 2 and Group 3 (p ˂ 0.01). In contrast, the number of patients prescribed UPA increased between Group 2 and Group 3 (p ˂ 0.01). Conclusions: These data suggest that the warnings issued for TOFA were followed by a reduction in total JAKi prescriptions. However, the more selective JAKi (UPA and FILGO) were perceived by prescribers as favorable in terms of the risk/benefit ratio, and their use gradually increased at the expense of the other molecules.

EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus and systemic sclerosis.

OBJECTIVE: To develop evidence-based recommendations for the non-pharmacological management of systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). METHODS: A task force comprising 7 rheumatologists, 15 other healthcare professionals and 3 patients was established. Following a systematic literature review performed to inform the recommendations, statements were formulated, discussed during online meetings and graded based on risk of bias assessment, level of evidence (LoE) and strength of recommendation (SoR; scale A-D, A comprising consistent LoE 1 studies, D comprising LoE 4 or inconsistent studies), following the European Alliance of Associations for Rheumatology standard operating procedure. Level of agreement (LoA; scale 0-10, 0 denoting complete disagreement, 10 denoting complete agreement) was determined for each statement through online voting. RESULTS: Four overarching principles and 12 recommendations were developed. These concerned common and disease-specific aspects of non-pharmacological management. SoR ranged from A to D. The mean LoA with the overarching principles and recommendations ranged from 8.4 to 9.7. Briefly, non-pharmacological management of SLE and SSc should be tailored, person-centred and participatory. It is not intended to preclude but rather complement pharmacotherapy. Patients should be offered education and support for physical exercise, smoking cessation and avoidance of cold exposure. Photoprotection and psychosocial interventions are important for SLE patients, while mouth and hand exercises are important in SSc. CONCLUSIONS: The recommendations will guide healthcare professionals and patients towards a holistic and personalised management of SLE and SSc. Research and educational agendas were developed to address needs towards a higher evidence level, enhancement of clinician-patient communication and improved outcomes.

Immunosuppressive therapy withdrawal after remission achievement in patients with lupus nephritis.

OBJECTIVES: Whether immunosuppressive therapy may be safely withdrawn in lupus nephritis (LN) is still unclear. We assessed rate and predictors of flare after IS withdrawal in patients with LN in remission. METHODS: Patients with biopsy-proven LN treated with immunosuppressants (IS) between 1980 and 2020 were considered. Remission was defined as normal serum creatinine, proteinuria <0.5 g/24 h, inactive urine sediment, and no extra-renal SLE activity on stable immunosuppressive and/or antimalarial therapy and/or prednisone ≤5mg/day. IS discontinuation was defined as the complete withdrawal of immunosuppressive therapy, flares according to SLEDAI Flare Index. Predictors of flare were analysed by multivariate logistic regression analysis. RESULTS: Among 513 SLE patients included in our database, 270 had LN. Of them, 238 underwent renal biopsy and were treated with IS. Eighty-three patients (34.8%) discontinued IS, 46 (30) months after remission achievement. During a mean (s.d.) follow-up of 116.5 (78) months, 19 patients (22.9%) developed a flare (8/19 renal) and were re-treated; 14/19 (73.7%) re-achieved remission after restarting therapy. Patients treated with IS therapy for at least 3 years after remission achievement had the lowest risk of relapse (OR 0.284, 95% CI: 0.093, 0.867; P = 0.023). At multivariate analysis, antimalarial maintenance therapy (OR 0.194, 95% CI: 0.038, 0.978; P = 0.047), age at IS discontinuation (OR 0.93, 95% CI: 0.868, 0.997; P = 0.040), remission duration >3 years before IS discontinuation (OR 0.231, 95% CI: 0.058, 0.920; P = 0.038) were protective against disease flares. CONCLUSIONS: Withdrawal of IS is feasible in LN patients in remission for at least 3 years and on antimalarial therapy. Patients who experience flares can re-achieve remission with an appropriate treatment.

Characterisation of a high-risk profile for maternal thrombotic and severe haemorrhagic complications in pregnant women with antiphospholipid syndrome in France (GR2): a multicentre, prospective, observational study.

BACKGROUND: Prospective data about the risks of thrombotic and severe haemorrhagic complications during pregnancy and post partum are unavailable for women with antiphospholipid syndrome. We aimed to assess thrombotic and haemorrhagic events in a prospective cohort of pregnant women with antiphospholipid syndrome. METHODS: This multicentre, prospective, observational study was done at 76 centres in France. To be eligible for this study, women had to have diagnosis of antiphospholipid syndrome; have conceived before April 17, 2020; have an ongoing pregnancy that had reached 12 weeks of gestation; and be included in the study before 18 weeks of gestation. Exclusion criteria were active systemic lupus erythematosus nephropathy, or a multifetal pregnancy. Severe haemorrhage was defined as the need for red blood cell transfusion or maternal intensive care unit admission because of bleeding or invasive procedures, defined as interventional radiology or surgery, to control bleeding. The GR2 study is registered with ClinicalTrials.gov, NCT02450396. FINDINGS: Between May 26, 2014, and April 17, 2020, 168 pregnancies in 27 centres met the inclusion criteria for the study. 89 (53%) of 168 women had a history of thrombosis. The median term at inclusion was 8 weeks gestation. 16 (10%) of 168 women (95%CI 5-15) had a thrombotic (six [4%] women; 95% CI 1-8) or severe haemorrhagic event (12 [7%] women; 95% CI 4-12). There were no deaths during the study. The main risk factors for thrombotic events were lupus anticoagulant positivity at inclusion (six [100%] of six women with thrombosis vs 78 [51%] of 152 of those with no thrombosis; p=0·030) and placental insufficiency (four [67%] of six women vs 28 [17%] of 162 women; p=0·013). The main risk factors for severe haemorrhagic events were pre-existing maternal hypertension (four [33%] of 12 women vs 11 [7%] of 156 women; p=0·014), lupus anticoagulant positivity at inclusion (12 [100%] of 12 women vs 72 [49%] of 146 women; p<0·0001) and during antiphospholipid history (12 [100%] of 12 women vs 104 [67%] of 156 women; p=0·019), triple antiphospholipid antibody positivity (eight [67%] of 12 women vs 36 [24%] of 147 women; p=0·0040), placental insufficiency (five [42%] of 12 women vs 27 [17%] of 156 women; p=0·038), and preterm delivery at 34 weeks or earlier (five [45%] of 11 women vs 12 [8%] of 145 women; p=0·0030). INTERPRETATION: Despite treatment adhering to international recommendations, a proportion of women with antiphospholipid syndrome developed a thrombotic or severe haemorrhagic complication related to pregnancy, most frequently in the post-partum period. Lupus anticoagulant and placental insufficiency were risk factors for these life-threatening complications. These complications are difficult to prevent, but knowledge of the antenatal characteristics associated with them should increase awareness and help physicians manage these high-risk pregnancies.

Durable renal response and safety with add-on belimumab in patients with lupus nephritis in real-life setting (BeRLiSS-LN). Results from a large, nationwide, multicentric cohort.

BACKGROUND: Belimumab was recently approved for treatment of lupus glomerulonephritis (LN). AIM: To evaluate renal response and its predictors in LN patients receiving belimumab in real-life. PATIENTS AND METHODS: We considered all patients fulfilling the SLEDAI-2K renal items and/or having estimated glomerular filtration rate (eGFR)≤60 ml/min/1.73 m2, with positive anti-dsDNA and/or low C3/C4 enrolled in the multicentre Italian lupus cohort BeRLiSS (BElimumab in Real LIfe Setting Study), treated with monthly IV Belimumab 10 mg/kg over standard treatment. Primary efficacy renal response (PERR), defined as proteinuria ≤0.7 g/24 h, eGFR≥60 ml/min/1.73 m2 without rescue therapy, was considered as primary outcome. Complete renal response (CRR; proteinuria <0.5 g/24 h, eGFR≥90 ml/min/1.73 m2) was considered as secondary outcome. Prevalence and predictors of PERR were evaluated at 6, 12, 24 months by multivariate logistic regression. RESULTS: Among the 466 SLE patients of BeRLiSS, 91 fulfilled the inclusion criteria, 79 females, median age 41.0 (33.0-47.0) years, median follow-up 22.0 (12.0-36.0) months. Sixty-four (70.3%) achieved PERR, of whom 38.4% reached CRR. Among patients achieving PERR at 6 months, 86.7% maintained response throughout the follow-up. At multivariable analysis, hypertension (OR [95%CI]: 0.28 [0.09-0.89], p = 0.032), high baseline serum creatinine (0.97 [0.95-0.99], p = 0.01) and high baseline proteinuria (0.37, [0.19-0.74], p = 0.005) negatively predicted PERR. Positive predictors of PERR at 12 and 24 months were baseline anti-Sm positivity (OR [95%CI]: 6.2 [1.21-31.7], p = 0.029; 19.8 [2.01-186.7], p = 0.009, respectively) and having achieved PERR at 6 months (14.4 [3.28-63.6]; 11.7 [2.7-48.7], p = 0.001 for both). CONCLUSIONS: Add-on therapy with belimumab led to durable renal response in patients with LN in a real-life setting.

Therapy of scleroderma renal crisis: State of the art.

Scleroderma renal crisis (SRC) is an uncommon but still life-threatening manifestation of systemic sclerosis (SSc). The incidence of SRC has decreased in the last few decades, probably due to a widespread use of vasodilators in SSc patients. It is well-recognized that exposure to different drugs can trigger SRC (corticosteroids, cyclosporine) or might prevent its occurrence (iloprost, calcium channel blockers). The prognosis of this life-threatening manifestation has not substantially improved since 1980s, when ACE-inhibitors were introduced in its treatment. ACE-inhibitors remain the mainstay in the therapy of SRC due to their efficacy in controlling malignant hypertension; indeed, the prognosis largely depends on the rapid improvement of the ongoing renal ischemia. Calcium-channel blockers and in third line diuretics and alpha-blockers should be used as additional therapy if blood pressure control remains suboptimal despite maximum tolerated doses of ACE-inhibitors. Given the growing evidence on the role of complement activation and endothelin-1 in the pathogenesis of SRC, recent case-series and case reports have suggested the use of C5-inhibitors and endothelin receptor antagonists in the therapy of SRC, mainly in the refractory cases. Plasma-exchange seems to give some benefits in patients with SRC and microangiopathy or intolerant to ACE-inhibitors. Renal transplantation is the last treatment option and its outcome is similar to that reported in other connective tissue disorders, with a 5-year patient survival rate of about 82%. In this review we summarize the current knowledge in the treatment of SRC.
