ABSTRACT
BACKGROUND: According to recent data, the age of patients could represent an important risk factor for MACE (major cardiovascular events), cancer, and VTE (venous thromboembolism) during treatment with JAK inhibitors in rheumatoid arthritis. We decided to analyze the population involved in the ReLiFiRa study by identifying two groups of patients: 65 years or more and less than 65 years of age, evaluating the efficacy and tolerability of 200 mg of Filgotinib daily. METHODS: Of the 120 ReLiFiRa patients, 54 were younger than 65 years old and 66 patients were 65 years old or older. The data of efficacy and tolerability of treatment with FIL 200 mg daily for 6 months were evaluated. RESULTS: After six months of treatment, FIL was effective in both age groups. In both groups, the median values of steroid DAS28, CDAI, ERS, PCR, tender joints, swollen joints, VAS, HAQ, PGA patients, and PGA physicians were reduced with a statistically significant difference comparing these values with the baseline values. The difference in age did not impact the effectiveness of the drug. The lipid profile data also did not demonstrate significant differences between the two age groups; however, the comparison between younger vs. older patients' populations regarding the total cholesterol/HDL ratio and LDL/HDL ratio shows a statistically significant difference: total cholesterol/HDL 3.4 (2.12-3.66) vs. 3.64 (3.36-4.13) p = 0.0004, LDL/HDL 1.9 (0.98-2.25) vs. 2.41 (2.04-2.73) p = 0.0002. There are no differences regarding the atherogenic index (LDL-C/HDL-C) and coronary risk index (TC/HDL-C) compared to baseline. CONCLUSIONS: After six months of treatment with FIL, the older population group showed a higher level of LDL and a lower level of HDL compared to younger patients. The atherogenic index and coronary risk index are higher in patients aged ≥ 65 years, but interestingly, there were no differences when comparing the 6-month data to baseline values. This condition highlights the impact of typical risk factors that act independently of treatment with Filgotinib.
ABSTRACT
OBJECTIVES: To characterize the effect of upadacitinib 15 mg once daily (UPA15) on enthesitis in patients with psoriatic arthritis from the SELECT-PsA Phase 3 trials. METHODS: Patients with an inadequate response/intolerance to ≥ 1 non-biologic DMARD (SELECT-PsA 1) or ≥ 1 biologic DMARD (SELECT-PsA 2) received UPA15, adalimumab 40 mg every other week or placebo (weeks 0-24) switched to UPA15 (week 24 onward). The Leeds Enthesitis Index (LEI) and Spondyloarthritis Research Consortium of Canada (SPARCC) index were used to assess improvement in enthesitis, enthesitis resolution, maintenance of enthesitis resolution, and protection from enthesitis development through week 56. RESULTS: Data from 639 patients receiving UPA15 and 635 patients receiving placebo (including 317 patients who switched from placebo to UPA15) were analysed. UPA15 led to higher rates of enthesitis resolution vs placebo at week 24 (LEI: 59.8% vs 38.0%; SPARCC index: 50.6% vs 31.5%, respectively) and greater improvements in the LEI (-1.7 vs -1.0) and SPARCC index (-3.4 vs -1.9); improvements were maintained through week 56. Improvements were observed after 12 weeks of UPA15 treatment. Over 90% of patients without enthesitis (LEI = 0) at baseline receiving UPA15 were enthesitis-free at week 56, and UPA15 prevented recurrence of enthesitis at week 56 in > 80% of patients with enthesitis at baseline who achieved resolution (LEI = 0) at week 24. CONCLUSIONS: UPA15 is associated with a comprehensive improvement in enthesitis, with improvements observed after 12 weeks of treatment. Additionally, treatment with UPA15 was associated with maintaining an enthesitis-free state after resolution and protection against new-onset enthesitis.

ABSTRACT
Introduction: IFN-γ release assays (IGRAs) are one of the referral tests for diagnosing tuberculosis infection (TBI). To improve IGRAs accuracy, several markers have been investigated. Patients with immune-mediated inflammatory diseases (IMID), taking biological drugs, have a higher risk to progress to TB-disease compared to the general population. In several guidelines, annual TBI screening is recommended for patients undergoing biological therapy. Aim of this study was to investigate, within the QuantiFERON-TB-Plus (QFT-Plus) platform, if beside IFN-γ, alternative biomarkers help to diagnose TBI-IMID patients. Methods: We enrolled 146 subjects: 46 with TB disease, 20 HD, 35 with TBI and 45 with TBI and IMID. Thirteen IMID subjects with a QFT-Plus negative result were diagnosed as TBI based on radiological evidence of TBI. We evaluated the IP-10 level in response to TB1 and TB2 peptides of QFT-Plus assay and we compared these results with the standardized assay based on IFN-γ. Multiplex immune assay was performed on plasma from TB1 and TB2 tubes and results were analyzed by a gradient boosting machine (GBM) as learning technique. Results: TBI-IMID showed a significant decreased IP-10 level in response to TB1 and TB2 stimulation compared to TBI-NO IMID (p < 0.0001 and p = 0.0002). The TBI-IMID showed a moderate agreement between the IP-10-based assay and QFT-Plus scores. In TBI-IMID, QFT-Plus showed 70% sensitivity for TBI detection whereas the IP-10-based assay reached 61%. Tests combination increased the sensitivity for TBI diagnosis up to 77%. By a GBM, we explored alternative biomarkers for diagnosing TBI in IMID population reaching 89% sensitivity. In particular, the signature based on IL-2, IP-10, and IL-9 detection was associated with TB status (infection/disease). However, by applying the cut-off identified by ROC analysis, comparing TB and TBI with the HD group, within the IMID population, we did not improve the accuracy for TBI-diagnosis. Similarly, this signature did not improve TBI diagnosis in IMID with radiological evidence of TBI but negative QFT-Plus score. Discussion: To develop alternative strategies for TBI immune-diagnosis, future studies are needed to evaluate the memory response of TBI defined by radiological tools. These results may help in tuberculosis management of patients taking lifelong immune-suppressive drugs.
ABSTRACT
Background: Psoriatic arthritis (PsA) is a chronic inflammatory musculoskeletal disease involving several articular and extra-articular structures. Despite the important progresses recently made in all of the aspects of this disease, its management is still burdened by unresolved issues. The aim of this exercise was to provide a set of statements that may be helpful for the management of PsA. Methods: A group of 38 Italian rheumatologists with recognized expertise in PsA selected and addressed the following four topics: "early PsA," "axial-PsA," "extra-articular manifestations and comorbidities," "therapeutic goals." Relevant articles from the literature (2016-2022) were selected by the experts based on a PubMed search. A number of statements for each topic were elaborated. Results: Ninety-four articles were selected and evaluated, 68 out of the 1,114 yielded by the literature search and 26 added by the Authors. Each of the four topic was subdivided in themes as follows: transition from psoriasis to PsA, imaging vs. CASPAR criteria in early diagnosis, early treatment for "early PsA"; axial-PsA vs. axialspondyloarthritis, diagnosis, clinical evaluation, treatment, standard radiography vs. magnetic resonance imaging for "axial PsA"; influence of inflammatory bowel disease on the therapeutic choice, cardiovascular comorbidity, bone damage, risk of infection for "comorbidities and extra-articular manifestations"; target and tools, treat-to-target strategy, role of imaging for "therapeutic goals." The final document consisted of 49 statements. Discussion: The final product of this exercise is a set of statements concerning the main issues of PsA management offering an expert opinion for some unmet needs of this complex disease.
ABSTRACT
BACKGROUND: Filgotinib (FIL) is a selective JAK1 inhibitor with an affinity 30-fold higher than JAK2, approved to treat moderate to severe active rheumatoid arthritis (RA), in adults with inadequate response or intolerance to one or more disease-modifying antirheumatic drugs (DMARDs). METHODS: We conducted a retrospective, multicentric study in order to evaluate efficacy and safety of FIL 200 mg daily therapy, after 3 and 6 months, in 120 patients affected by RA, managed in Tuscany and Umbria rheumatological centers. The following clinical records were analyzed: demographical data, smoking status, previous presence of comorbidities (Herpes zoster -HZ- infection, venous thromboembolism -VTE-, major adverse cardiovascular events -MACE-, cancer, diabetes, and hypertension), disease duration, presence of anti-citrullinated protein antibodies (ACPA), rheumatoid factor (RF), number of biological failures, and prior csDMARDs utilized. At baseline, and after 3 (T3) and 6 (T6) months of FIL therapy, we evaluated mean steroid dosage, csDMARDs intake, clinimetric indexes (DAS28, CDAI, HAQ, patient and doctor PGA, VAS), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and body mass index (BMI). RESULTS: At baseline, the mean disease duration was 9.4 ± 7.5 years; the prevalence of previous HZ infection, VTE, MACE, and cancer was respectively 4.12%, 0%, 7.21%, and 0.83%, respectively. In total, 76.3% of patients failed one or more biologics (one biological failure, 20.6%; two biological failures, 27.8%; three biological failures, 16.5%; four biological failures, 10.3%; five biological failures, 1.1%). After 3 months of FIL therapy, all clinimetric index results significantly improved from baseline, as well as after 6 months. Also, ESR and CRP significatively decreased at T3 and T6. Two cases of HZ were recorded, while no new MACE, VTE, or cancer were recorded during the observation time. CONCLUSION: Despite the limitations of the retrospective study and of the observational period of only 6 months, real-life data on the treatment of RA patients with FIL demonstrate that this Jak inhibitor therapy is safe in terms of CV, VTE events, and occurrence of cancer, and is also effective in a population identified as "difficult to treat" due to failure of previous b-DMARD therapy.
ABSTRACT
BACKGROUND: Immune and vascular ageing are proposed risk factors for giant cell arteritis (GCA). Data on the impact of age at diagnosis of GCA on the clinical presentation and course of the disease are scarce. METHODS: Patients with GCA followed at referral centres within the Italian Society of Rheumatology Vasculitis Study Group were enrolled up to November 2021. Patients were grouped according to age at diagnosis: ≤64, 65-79 and ≥80 years old. RESULTS: The study included 1004 patients, mean age 72.1±8.4, female 70.82%. Median follow-up duration was 49 (IQR 23-91) months. Patients in the oldest group (≥80 years) had significantly more cranial symptoms, ischaemic complications and risk for blindness compared with the groups 65-79 and ≤64 years (blindness: 36.98% vs 18.21% vs 6.19%; p<0.0001). Large-vessel-GCA was more frequent in the youngest group (65% of patients). Relapses occurred in 47% of patients. Age did not influence the time to first relapse, nor the number of relapses. Older age was negatively associated with the number of adjunctive immunosuppressants. Patients >65 years old had 2-3 fold increased risk for aortic aneurysm/dissection up to 60 months follow-up. Serious infections, but not other treatment-related complications (hypertension, diabetes, osteoporotic fractures), were significantly associated with older age. Mortality occurred in 5.8% of the population with age >65, cranial and systemic symptoms as independent risk factors. CONCLUSIONS: The highest risk of ischaemic complications, aneurysm development, serious infections and the possible undertreatment make of GCA a very challenging disease in the oldest patients.

Data on the risk of adverse events (AEs) and disease flares in autoimmune rheumatic diseases (ARDs) after the third dose of COVID-19 vaccine are scarce. The aim of this multicenter, prospective study is to analyze the clinical and immunological safety of BNT162b2 vaccine in a cohort of rheumatoid arthritis (RA) patients followed-up from the first vaccine cycle to the third dose. The vaccine showed an overall good safety profile with no patient reporting serious AEs, and a low percentage of total AEs at both doses (40/78 (51.3%) and 13/47 (27.7%) patients after the second and third dose, respectively (p < 0.002). Flares were observed in 10.3% of patients after the end of the vaccination cycle and 12.8% after the third dose. Being vaccinated for influenza was inversely associated with the onset of AEs after the second dose, at both univariable (p = 0.013) and multivariable analysis (p = 0.027). This result could allow identification of a predictive factor of vaccine tolerance, if confirmed in larger patient populations. A higher disease activity at baseline was not associated with a higher incidence of AEs or disease flares. Effectiveness was excellent after the second dose, with only 1/78 (1.3%) mild breakthrough infection (BI) and worsened after the third dose, with 9/47 (19.2%) BI (p < 0.002), as a probable expression of the higher capacity of the Omicron variants to escape vaccine recognition.
ABSTRACT
OBJECTIVES: Interstitial lung disease (ILD) has been described as a possible pulmonary involvement in antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitides (AAV), mainly granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). Aim of this cross-sectional Italian national study was to describe demographic, clinical and serological profile of ILD related to MPA and GPA and investigate possible correlations between radiologic patterns of ILD and vasculitis features. METHODS: We enrolled 95 consecutive patients with AAV-ILD, 56 affected by MPA (58.9%) and 39 by GPA (41.1%). RESULTS: NSIP was the most frequently detected ILD pattern, observed in c-ANCA patients in 60.9% of cases, followed by UIP pattern mainly observed in p-ANCA patients (47.7%, p=0.03). ILD represented the first clinical manifestation, preceding vasculitis diagnosis in 22.1% of cases and, globally, ILD was already detectable at AAV diagnosis in 66.3% of patients. The diagnosis of ILD preceded that of AAV in 85.7% of p-ANCA positive-patients, while only one patient with c-ANCA developed ILD before AAV (p= 0.039). Multivariate analysis confirmed the correlation of UIP pattern with p-ANCA-positivity and a diagnosis of ILD before AAV, also when adjusted for age and sex. CONCLUSIONS: Our study confirms that UIP is a frequent pattern of lung disease in AAVILD patients. Our results also suggest that ILD can represent an early complication of AAV but also occur in the course of the disease, suggesting the need of a careful evaluation by both pulmonologist and rheumatologist to achieve an early diagnosis. Further prospective studies are needed to define ILD prevalence and evolution in AAV patients.

OBJECTIVES: To characterize the kinetics of humoral and T-cell responses in rheumatoid arthritis (RA)-patients followed up to 4-6 weeks (T3) after the SARS-CoV-2 vaccine booster dose. METHODS: Health care workers (HCWs, n = 38) and patients with RA (n = 52) completing the messenger RNA vaccination schedule were enrolled at T3. In each cohort, 25 subjects were sampled after 5 weeks (T1) and 6 months (T2) from the first vaccine dose. The humoral response was assessed by measuring anti-receptor-binding domain (RBD) and neutralizing antibodies, the T-cell response by interferon-γ-release assay (IGRA), T cell cytokine production, and B cell phenotype at T3 by flow cytometry. RESULTS: Patients with RA showed a significant reduction of antibody titers from T1 to T2 and a significant increase at T3. T-cell response by IGRA persisted over time in patients with RA, whereas it increased in HCWs. Most patients with RA scored positive for anti-RBD, neutralizing antibody and T-cell responses, although the magnitude was lower than HCWs. The spike-specific-cytokine response was mainly clusters of differentiation (CD)4+ T cells restricted in both cohorts and significantly lower with reduced interleukin-2 response and CD4-antigen-responding naïve T cells in patients with RA. Unswitched memory B cells were reduced in patients with RA compared with HCWs independently of vaccination. CONCLUSION: COVID-19 vaccine booster strengthens the humoral immunity in patients with RA even with a reduced cytokine response.

Vaccination has been a game changer in our efforts to address the coronavirus disease 2019 (COVID-19) pandemic. However, the disease might still represent a clinical crisis for several more years, in part because of the inevitable emergence of variants capable of evading the preexisting immunity. Drugs affecting viral spread will help curtail transmission, but therapeutics are needed to treat the more severe cases requiring hospitalization. A deep analysis of the evolving immune landscape of COVID-19 suggests that understanding the molecular bases of the distinct clinical stages is paramount if we are to limit the burden of inflammation, which can lead to death in frail individuals, according to age, sex, and comorbidities. Different phases can be defined using immune biomarkers and need specific therapeutic approaches, tailored to the underlying immune contexture.

INTRODUCTION: In 2015, the Italian board for the TAilored BIOlogic therapy (ITABIO) proposed evidence-based decisional statements for first-line tailored biologic therapy in patients with rheumatoid arthritis (RA). Taking into account the new licensed drugs, the aim of the present review was to update the previous statements. AREAS COVERED: A narrative review of the most recent evidence on the efficacy and safety of old and newly licensed drugs for the treatment of articular and extra-articular RA was performed. In addition, host-related variables potentially driving the therapy choice, such as the infection risk, the cardiovascular risk, the risk of deep vein thrombosis, thromboembolism, pregnancy, and obesity were analyzed. Consequently, several statements for personalized therapy were formulated, thus providing a decisional algorithm useful for proper personalized therapy of RA patients in clinical practice. EXPERT OPINION: Several clinical variables related to specific drug and host characteristics may drive the choice toward anti-TNF and non-anti-TNF biologics, or anti-JAKs, thus allowing to personalize the therapy. Consequently, the right therapy for the right patient would ensure a successful therapeutic intervention.

Subjects with immune-mediated inflammatory diseases (IMID), such as rheumatoid arthritis (RA), have an intrinsic higher probability to develop active-tuberculosis (TB) compared to the general population. The risk ranges from 2.0 to 8.9 in RA patients not receiving therapies. According to the WHO, the RA prevalence varies between 0.3% and 1% and is more common in women and in developed countries. Therefore, the identification and treatment of TB infection (TBI) in this fragile population is important to propose the TB preventive therapy. We aimed to study the M. tuberculosis (Mtb) specific T-cell response to find immune biomarkers of Mtb burden or Mtb clearance in patients with different TB status and different risk to develop active-TB disease. We enrolled TBI subjects as example of Mtb-containment, the active-TB as example of a replicating Mtb status, and the TBI-IMID as fragile population. To study the Mtb-specific response in a condition of possible Mtb sterilization, we longitudinally enrolled TBI subjects and active-TB patients before and after TB therapy. Peripheral blood mononuclear cells were stimulated overnight with Mtb peptides contained in TB1- and TB2-tubes of the Quantiferon-Plus kit. Then, we characterized by cytometry the Mtb-specific CD4 and CD8 T cells. In TBI-IMID, the TB therapy did not affect the ability of CD4 T cells to produce interferon-γ, tumor necrosis factor-α, and interleukin-2, their functional status, and their phenotype. The TB therapy determined a contraction of the triple functional CD4 T cells of the TBI subjects and active-TB patients. The CD45RA- CD27+ T cells stood out as a main subset of the Mtb-specific response in all groups. Before the TB-preventive therapy, the TBI subjects had higher proportion of Mtb-specific CD45RA-CD27+CD4+ T cells and the active-TB subjects had higher proportion of Mtb-specific CD45RA-CD27-CD4+ T cells compared to other groups. The TBI-IMID patients showed a phenotype similar to TBI, suggesting that the type of IMID and the IMID therapy did not affect the activation status of Mtb-specific CD4 T cells. Future studies on a larger and better-stratified TBI-IMID population will help to understand the change of the Mtb-specific immune response over time and to identify possible immune biomarkers of Mtb-containment or active replication.

OBJECTIVE: Baricitinib seems a promising therapy for COVID-19. To fully-investigate its effects, we in-vitro evaluated the impact of baricitinib on the SARS-CoV-2-specific-response using the whole-blood platform. METHODS: We evaluated baricitinib effect on the IFN-γ-release and on a panel of soluble factors by multiplex-technology after stimulating whole-blood from 39 COVID-19 patients with SARS-CoV-2 antigens. Staphylococcal Enterotoxin B (SEB) antigen was used as a positive control. RESULTS: In-vitro exogenous addition of baricitinib significantly decreased IFN-γ response to spike- (median: 0.21, IQR: 0.01-1; spike+baricitinib 1000â¯nM median: 0.05, IQR: 0-0.18; p < 0.0001) and to the remainder-antigens (median: 0.08 IQR: 0-0.55; remainder-antigens+baricitinib 1000â¯nM median: 0.03, IQR: 0-0.14; pâ¯=â¯0.0013). Moreover, baricitinib significantly decreased SEB-induced response (median: 12.52, IQR: 9.7-15.2; SEB+baricitinib 1000â¯nM median: 8, IQR: 1.44-12.16; p < 0.0001). Baricitinib did modulate other soluble factors besides IFN-γ, significantly decreasing the spike-specific-response mediated by IL-17, IL-1ß, IL-6, TNF-α, IL-4, IL-13, IL-1ra, IL-10, GM-CSF, FGF, IP-10, MCP-1, MIP-1ß (pâ¯≤â¯0.0156). The baricitinib-decreased SARS-CoV-2-specific-response was observed mainly in mild/moderate COVID-19 and in those with lymphocyte count ≥1â¯×â¯103/µl. CONCLUSIONS: Exogenous addition of baricitinib decreases the in-vitro SARS-CoV-2-specific response in COVID-19 patients using a whole-blood platform. These results are the first to show the effects of this therapy on the immune-specific viral response.

OBJECTIVES: To evaluate the health-related quality of life (HRQoL), disease activity, treatment adherence, and work ability in the real-world setting in patients with axial spondyloarthritis (axSpA). METHODS: QUASAR was a prospective 12-month, observational study involving 23 rheumatology centres across Italy, including adult patients with axSpA according to the Assessment of SpondyloArthritis International Society (ASAS) criteria. Patients were followed at baseline, 3, 6, and 12 months for disease activity and health-related QoL (HRQoL), treatment adherence and work ability. Regression analysis was used to assess the association between treatment and outcome variables. RESULTS: 413 (80.7%) out of axSpA 512 patients were diagnosed with ankylosing spondylitis (AS) and 99 (19.3%) with non-radiographic axSpA (nr-axSpA). Nr-axSpA and AS patients had similar baseline disease activity and HRQoL. Biologic disease-modifying anti-rheumatic drugs (bDMARDs) were the most frequent medication (n=426, 83.2%). Over the 1-year follow-up, disease activity measures (joint pain and swelling, CRP, global assessment, BASDAI, ASDAS), HRQoL and work ability significantly improved, while few differences emerged between nr-axSpA and AS patients. Treatment satisfaction and adherence questionnaires improved over the 12 months. Patients treated with bDMARDs showed improved outcomes for disease activity measures and HRQoL variables, greater benefit observed in patients with AS. CONCLUSIONS: We found clinical and HRQoL improvement over 1 year in a large, real-world population of nr-axSpA and AS patients treated with bDMARDs or conventional synthetic DMARDs.

OBJECTIVES: To examine whether specific T-cell-responses to SARS-CoV-2 peptides can be detected in COVID-19 using a whole-blood experimental setting, which may be further explored as a potential diagnostic tool. METHODS: We evaluated interferon (IFN)-γ levels after stimulating whole-blood with spike and remainder-antigens peptides megapools (MP) derived from SARS-CoV-2 sequences; interleukin (IL)-1ß, IL-1RA, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12p70, IL-13, IL-15, IL-17A, eotaxin, basic fibroblast growth factor (FGF), granulocyte-colony stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), IFN-γ, Interferon gamma-induced protein 10 (IP-10), monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein (MIP)-1α, MIP-1ß, Platelet-derived growth factor (PDGF), RANTES (regulated on activation, normal T cell expressed and secreted), tumour necrosis factor-alpha (TNF-α), vascular endothelial growth factor (VEGF) were also evaluated. RESULTS: IFN-γ-response to spike and remainder-antigens MPs was significantly increased in 35 COVID-19 patients compared with 29 'no COVID-19' individuals (medians spike-MP: 0.26 vs 0, p = 0.0002; medians remainder-antigens-MP: 0.07 vs 0.02; p = 0.02). This response was detected independently of patients' clinical parameters. IFN-γ-response to SARS-CoV-2-unrelated antigens cytomegalovirus (CMV) and Staphylococcal Enterotoxin B (SEB) was similar in COVID-19 compared with 'no COVID-19' individuals (median CMV: 3.46 vs 5.28, p = 0.16; median SEB: 12.68 vs 15.05; p = 0.1). In response to spike-MPs in COVID-19- compared with 'no COVID-19' -individuals, we found significant higher median of IL-2 (50.08 vs 0, p = 0.0018), IFN-γ (90.16 vs 0, p = 0.01), IL-4 (0.52 vs 0, p = 0.03), IL-13 (0.84 vs 0, p = 0.007) and MCP-1 (4602 vs 359.2, p = 0.05). CONCLUSIONS: Immune response to SARS-CoV-2 peptides in a whole-blood assay is associated with COVID-19 and it is characterized by both Th1 and Th2 profile. This experimental approach may be useful for developing new T-cell based diagnostic tests for disease and vaccine settings.

Using AI, we identified baricitinib as having antiviral and anticytokine efficacy. We now show a 71% (95% CI 0.15 to 0.58) mortality benefit in 83 patients with moderate-severe SARS-CoV-2 pneumonia with few drug-induced adverse events, including a large elderly cohort (median age, 81 years). An additional 48 cases with mild-moderate pneumonia recovered uneventfully. Using organotypic 3D cultures of primary human liver cells, we demonstrate that interferon-α2 increases ACE2 expression and SARS-CoV-2 infectivity in parenchymal cells by greater than fivefold. RNA-seq reveals gene response signatures associated with platelet activation, fully inhibited by baricitinib. Using viral load quantifications and superresolution microscopy, we found that baricitinib exerts activity rapidly through the inhibition of host proteins (numb-associated kinases), uniquely among antivirals. This reveals mechanistic actions of a Janus kinase-1/2 inhibitor targeting viral entry, replication, and the cytokine storm and is associated with beneficial outcomes including in severely ill elderly patients, data that incentivize further randomized controlled trials.

BACKGROUND: Based on current evidence, recent guidelines of the National Institute of Health, USA indicated the use of remdesivir and dexamethasone for the treatment of COVID-19 patients with mild-moderate disease, not requiring high-flow oxygen. No therapeutic agent directed against the immunologic pathogenic mechanisms related to the cytokine release syndrome complicating the disease was indicated. OBJECTIVES: The purpose of this review was to assess the clinical impact of different therapies for COVID-19; thus, helping to identify the optimal management of the disease. To explain the rationale for the different therapeutic approaches, the characteristics of SARS-CoV-2, the pathogenesis of COVID-19, and the immune response triggered by SARS-CoV-2 infection were reported. METHODS: The efficacy assessment of the different treatments was performed by a systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Available English language published articles including randomised controlled trials, open-label trials of antivirals and immune therapies extracted from Medline, Google Scholar, and MedRxiv databases were analysed. For inclusion, the primary end point of the trials had to be the efficacy as measured by the improvement of clinical features, or mortality, or the Intensive Care Unit Admission rate, or the discharge number. Case reports, paediatric studies, and studies without control group were excluded. The literature search was extended up to August 15, 2020. RESULTS: After the removal of duplicate articles, and the exclusion of studies not meeting the eligibility criteria, 2 trials of lopinavir/ritonavir, 1 of favipiravir, 3 of remdesivir, 1 of dexamethasone, 3 of hydroxychloroquine, 2 of colchicine, 6 of tocilizumab, 1 of sarilumab, 1 of siltuximab, 2 of anakinra, 3 of baricitinib, 1 of ruxolitinib, 1 of mavrilimumab, and 1 of itolizumab were suitable for the review. Among antivirals, only remdesivir significantly reduced the time to recovery, and mortality. Data for chloroquine and hydroxychloroquine were largely inconclusive. In a large trial, dexamethasone 6 mg/day reduced mortality by one-third. Trials of tocilizumab and sarilumab did not definitively demonstrate efficacy. Anakinra significantly reduced the mortality in 2 trials. Three retrospective trials on a cumulative number of 145 patients, reported the efficacy of baricitinib, with significant reduction of intensive care unit admission, and deaths. These results were recently confirmed by the ACTT-2 trial. Due to paucity of studies and to the small size clinical series, the results of other immune therapies were not conclusive. CONCLUSIONS: Beyond the supportive therapy, up to now the best therapeutic approach for COVID-19 may be a three-step combination therapy, including remdesivir 100 mg/day (200 mg loading dose on first day) in the first stage of the disease, and combined dexamethasone 6 mg/day plus baricitinib 4 mg/day to target the immune dysregulation triggered by the SARS-CoV-2 infection. The promising results of anakinra should be confirmed by the ongoing RCTs.

INTRODUCTION: Janus kinases inhibitors (anti-JAKs), including tofacitinib, baricitinib, upadacitinib, and filgotinib, represent a new class of synthetic targeted drugs for the treatment of rheumatoid arthritis (RA). In this review, the risk of active tuberculosis (TB) occurrence in patients receiving anti-JAKs was assessed. The literature on this topic, updated to 29 February 2020 was reviewed. Overall, 40 reports (22 tofacitinib, 10 baricitinib, 5 upadacitinib, 3 filgotinib) were examined. A low frequency, not exceeding 0.25%, of active TB cases in patients were exposed to anti-JAKs. Only 1 of 89 recorded cases in tofactinib and baricitinib exposure occurred in countries at intermediate or high TB risk, and most of the cases probably were due to first mycobacterium tuberculosis (Mtb) exposure. Although no cases were observed in patients receiving upadacitinib and filgotinib, long-term trials and data from real-life are required to more precisely address the TB risk associated with the two drugs. AREAS COVERED: Discussion on the TB risk associated with anti-JAKs, and on the need for accurate evaluation of host-related risk factors in high risk countries. EXPERT OPINION: Available data on anti-JAKs suggest a negligible risk of active TB occurrence in low endemic areas.
