Patients with active RA despite standard DMARDs therapy and concomitant 2TDM were selected into one of five exposure groups to first-line bDMARDs (adalimumab, golimumab, etanercept, tocilizumab, sarilumab) and observed for the outcome of CRP, ESR, DAS28CRP and glycated hemoglobin (HbA1c) variations.Results: After the start of treatment, there was a significant reduction in the values of acute phase reactants ESR and CRP (p< 0.01), DAS28-CRP (p< 0.01) and HbA1C (p< 0.05), in the absence of any confounding factors such as a reduction in BMI or a change in steroid doses. There was no statistically significant difference between the various treatments. Anti-IL6 drugs appear to be associated with a slightly greater reduction in HbA1c values, bordering on statistical significance (p=0.047).Conclusion: Initiation of a bDMARD appears to be associated with an improvement in concomitant 2TDM in patients with active RA, which, in the first hypothesis, is linked with a reduction of the inflammatory milieu.Keywords: diabetes mellitus, rheumatoid arthritis, bDMARDs

Antonella Laria,1 Alfredo Maria Lurati,1 Katia Angela Re,1 Maria Grazia Marrazza,1 Daniela Mazzocchi,1 Alberto Farina,2 Magda Scarpellini,1 1Department of Rheumatology, Fornaroli Hospital, Magenta, Milan, Italy; 2Medical Affairs Department, Italfarmaco S.p.A., Cinisello Balsamo, Milan, Italy Purpose: Administration of intravenous iloprost – a first-line European League Against Rheumatism (EULAR)-recommended choice for the treatment of scleroderma (SSc)-related digital vasculopathy – requires repeated treatment cycles of 6 hours per day in a hospital setting. During the infusion, patient mobility is considerably restricted due to the size and fixity of traditional syringe pumps. The aim of this study was to evaluate the satisfaction level of patients and nurses, after the introduction of a new portable syringe pump (Infonde®, Italfarmaco S.p.A., Milan, Italy) at the Department of Rheumatology, Magenta Hospital, Milan, Italy. Patients and methods: Thirty-four consecutive SSc patients receiving stable therapy with iloprost, previously administered with a fixed pump, were treated using the portable Infonde® pump. Patients (n=34) and nurses (n=4) were asked to answer a nine- and six-item questionnaire, respectively, to assess the satisfaction of the administration comparing the new device versus the previous one. The health care staff of the ward developed the questionnaire, and the response scores ranged from 0 (fixed device better) to 10 (portable device better); thus a score >5 indicates a preference for Infonde®. Results: Patients' answers indicated a preference towards the new portable syringe pump, versus the previous fixed pump. Questionnaires administered to patients generated a total of 306 responses, with over 95% of the responses in the range 8–10, of which 89% had a score equal to 10. The responses of nurses showed a score equal to 10 in 100% cases. No significant adverse events were recorded, indicating no change in the tolerability profile of the drug. Conclusion: Iloprost administration with Infonde® pump was preferred by both patients and health care professionals, and was well tolerated. The possibility to perform daily activities and the freedom of movement suggest a positive impact of Infonde® on the treatment, with a potential favorable effect on the quality of life of patients during the many hours spent receiving the infusion.

Abstract: COVID-19 is causing a high influx of patients suffering from serious respiratory complications leading the necessity to find effective therapies. These patients seem to present with cytokine perturbation and high levels of IL6. Tocilizumab and sarilumab could be effective in this condition.We retrospectively collected data about 112 consecutive hospitalized in a single center.Fifty (IL6 group) treated with tocilizumab (8 mg/kg intravenously [IV], 2 infusions 12 hours apart) or sarilumab 400 mg IV once and 62 treated with the standard of care but not anti-cytokine drugs (CONTROL group).To determine whether anti-IL6 drugs are effective in improving prognosis and reducing hospitalization times and mortality in COVID-19 pneumonia.To date 84% (42/50) of IL6 group patients have already been discharged and only 2/50 are still recovered and intubated in intensive care. Six/fifty patients (12%) died: 5/6 due to severe respiratory failure within a framework of severe acute respiratory distress syndrome (ARDS), 1 suffered an acute myocardial infarction, and 1 died of massive pulmonary thromboembolism. There were no adverse treatment events or infectious complications. Compared to the CONTROL group they showed a lower mortality rate (12% versus 43%), for the same number of complications and days of hospitalization.Anti-IL6 drugs seem to be effective in the treatment of medium to severe forms of COVID-19 pneumonia reducing the risk of mortality due to multi-organ failure, acting at the systemic level and reducing inflammation levels and therefore microvascular complications. However, it is essential to identify the best time for treatment, which, if delayed, is rendered useless as well as counterproductive. Further studies and ongoing clinical trials will help us to better define patients eligible as candidates for more aggressive intervention., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 the Author(s).

Introduction: We investigated the relationship between the anti CD20 therapy and the NK cell phenotype in patients with Rheumatoid Arthritis (RA)., Methods: patients with seropositive RA according to the ACR criteria that was refractory to conventional and anti TNF alpha agents were studied. All patients were treated with Rituximab (1.0 g at days 1 and 15). At baseline and day 30 were collected: absolute counts of B cells (CD19+), total T cells (CD3+), helper (CD3+CD4+), cytotoxic (CD3+CD8+) and NK (CD16+CD56+). As NK activation marker was used CD54bright expression. Disease activity was primarily assessed using the the Clinical Disease Activity Index (CDAI); in addition, we calculated the Disease Activity Score 28-joint assessment (DAS28)., Results: 18 patients were enrolled (mean age ± SD 58.6 ± 2.8 years old). After the rituximab course, as expected CD19+ cells were not detectable, the cytotoxic lymphocytes and CD56+CD16+ cells downregulated (283 ± 34 and 85 ± 15 respectively), instead an up regulation of CD56+CD16+CD54bright was observed (187 ± 43). The dynamic of NK cells activation was significantly associated with clinical variables (r=0.811, p<0.001)., Conclusions: our data suggest a role of rituximab therapy in varying NK phenotype in patients with RA and show that NK cells activation correlates with clinical response.

Background: The purpose of the present study was to determine relationship between disease activity, systemic markers of cartilage degradation, urinary C-terminal cross-linking telopeptides of type II collagen (uCTX-II), and bone degradation, urinary C-terminal cross-linking telopeptides of type I collagen (uCTX-I), structural progression of osteoarthritis (OA) and potential therapeutic efficacy of type II collagen (COLLII) in combination with glucosamine and chondroitin sulfate (GC)., Materials and Methods: An observational retrospective study, 1-year follow-up, on 104 patients with OA (nodular osteoarthritis of the hand, erosive osteoarthritis of the hand, EOA, osteoarthritis of the knee or hip) who were treated with GC or glucosamine, chondroitin sulfate and collagen type II (GCC). The following information was collected at entry: demographics, BMI, characteristics of OA, patient global assessment (VAS), C-terminal cross-linking telopeptides of collagen types I (uCTX-I) and II (uCTX-II) and radiographs. After 6 months: VAS, uCTX-I and uCTX-II. After 1 year: VAS, uCTX-I, uCTX-II and radiographs., Results: After 6 months and 1 year of treatment VAS, uCTX-I and uCTX-II mean values were significantly lower than the baseline. 57 were treated with GCC and 47 with GC. The group that received GCC showed a similar VAS mean value after 6 months and 1 year when compared with the group treated with GC. uCTX-I and uCTX-II mean level was lower in the group treated with GCC (P < 0.05). Radiological score (Kellgren and Lawrence summarized score for hands) after 1 year showed a reduced progression compared to the baseline in the hand osteoarthritis group, especially after GCC treatment (P < 0.05). Finally, uCTX-I has better correlation with radiological score and with GC in the EOA subgroup (Pearson index: R = 0.44)., Conclusions: (a) uCTX-I and uCTX-II proved to be useful biomarkers in OA monitoring; (b) uCTX-I is better correlated with hand EOA and could represent a potential further marker to assess the evolution of EOA bone damage; (c) GC slow down OA progression; (d) finally COLLII could represent a further protective factor in OA cartilage.

Drug-induced lupus is a syndrome which share symptoms and laboratory characteristics with the idiopathic systemic lupus erythematosus (SLE). The list of medications implicated as etiologic agents in drug-induced lupus continues to grow. The terms used for this condition are lupus-like syndrome, drug-induced lupus erythematosus (DILE) and drug related lupus. More than 80 drugs have been associated with DILE. The first case of DILE was reported in 1945 and associated with sulfadiazin. In 1953 it was reported that DILE was related to the use of hydralazine. Drugs responsible for the development of DILE can divided into three groups, but the list of these drugs is quite long because new drugs are included yearly in the list. The syndrome is characterised by arthralgia, myalgia, pleurisy, rash and fever in association with antinuclear antibodies in the serum. Recognition of DILE is important because it usually reverts within a few weeks after stopping the drug.
