POS0507 TAILORING ORAL THERAPY IN RHEUMATOID ARTHRITIS: THE TuTOR APP

Background

Medication non-adherence has a significant impact on the health and well-being of individuals with chronic diseases. Indeed, with respect to important risk factors of Rheumatoid Arthritis (RA), such as cardiovascular risk factors, it is known that up to 50% of patients will stop taking medication for these conditions during the first year of prescription [1].

Objectives

To support the management of RA patients treated with Tofacitinib, we designed the TuTOR (Tailoring Tofacitinib Oral therapy in Rheumatoid arthritis) Mobile App.

Methods

A prospective-controlled study evaluated the impact of TuTOR App on medical adherence in 20 RA patients, that began treatment with Tofacitinib jointly with the App. We used a crossover design alternating Paper-Diary and TuTOR App, with monthly clinical assessments.

Results

Seventeen patients with RA (mean age at inclusion 59±13yrs; 88% females) the study. A statistically significant decrease of DAS28 was observed since the first month of therapy with Tofacitinib (mean DAS28 at baseline 3.9±1 vs. 1° month 3.1±1, p=0.0016). Similarly, Numerical Rating Scale(NRS) of perceived activity of disease (5.8±2.1 vs.3.7±2.5, p=0.02), and subjective fatigue (6.1±2.3 vs 4.3±2.6; p=0.01) progressively decreased. No differences were reported in DAS28 and in all the NRS between the use of the TuTOR App and the Paper-Diary. A significant decrease was observed also in HAQ during the follow-up (baseline 1.38±1.11 vs.six months 0.83±0.9; p=0.01).

Most of the patients (82%) when filling out the self-reporting questionnaires preferred the TuTOR App in helping them to remember to take the pills. Further 82% of patients used the TuTOR App regularly (vs.53% Paper-Diary) and 76% of patients would use it in the future (vs.53% Paper-Diary). Three patients suspended the therapy with Tofacitinib due to gastrointestinal intolerance.

Conclusion

Both digital- and paper-devices can help maximize the adherence to therapy, leading to an improvement in disease’s activity, highlighting the need of supports for medication adherence.

The adjusted Global AntiphosPholipid Syndrome Score (aGAPSS) for risk stratification in young APS patients with acute myocardial infarction

BACKGROUND

Young adults with acute myocardial infarction are a critical group to examine for the purpose of risk factor stratification and modification. In this study we aimed to assess the clinical utility of the adjusted Global AntiphosPholipid Syndrome Score (aGAPSS) for the risk stratification of acute myocardial infarction in a cohort of young patients with antiphospholipid syndrome (APS).

METHODS

The analysis included 83 consecutive APS patients (≤50years old) who presented with arterial or venous thromboembolic events. Data on cardiovascular risk factors and antiphospholipid antibodies (aPL) positivity were retrospectively collected. The aGAPSS was calculated by adding the points corresponding to the risk factors, based on a linear transformation derived from the ß-regression coefficient as follows: 3 for hyperlipidaemia, 1 for arterial hypertension, 5 for aCL IgG/IgM, 4 for anti-b2 glycoprotein I IgG/IgM and 4 for LA.

RESULTS

Higher aGAPSS values were observed in patients with acute myocardial infarction when compared to the others [mean aGAPSS 11.9 (S.D. 4.15, range 4-18) Vs. mean aGAPSS 9.2 (S.D. 5.1, range 1-17); T test: p<0.05]. Significantly higher aGAPSS values were also seen in patients with acute coronary syndrome compared to patients with a history of peripheral or cerebrovascular arterial thrombotic events [mean aGAPSS 11.9 (S.D. 4.15, range 4-18) Vs. mean aGAPSS 6.7 (S.D. 5.7, range 1-17); T test: P<0.005].

CONCLUSIONS

The aGAPSS is based upon a quantitative score and could aid risk stratifying APS patients younger than 50years for the likelihood of developing coronary thrombotic events and may guide pharmacological treatment for high-risk patients.

Evidence of trigonal dangling bonds at the Ge(111)/oxide interface by electrically detected magnetic resonance

Despite a renewed interest in Ge as a competitor with Si for a broad range of electronic applications, the microstructure and the electronic properties of the dangling bonds that, in analogy with Si, are expected at the Ge/oxide interface have escaped a firm spectroscopy observation and characterization. Clear evidence based on contactless electrically detected magnetic resonance spectroscopy of a dangling bond at the Ge(111)/GeO(2) interface is reported in this Letter. This result supports the similarity between dangling bonds at the Si(111)/oxide and Ge(111)/oxide interfaces, both showing C(3v) trigonal point symmetry with the main axis oriented along the ⟨111⟩ direction. In contrast, at the Ge(001)/oxide interface the absence of the trigonal center in favor of a lower symmetry dangling bond marks the difference with the Si(001)/oxide interface, where both centers are present and the one having higher point symmetry prevails. This fact is rationalized in terms of suboxide interface rearrangement and oxide viscoelasticity, which promote the generation of the nonaxial centers at distorted dimers. The unambiguous identification of the centers at the Ge/oxide interfaces yields a deeper insight into the physical properties of the suboxide interface structure and offers a valid indicator for the evaluation of different surface capping and passivation techniques, with the potential to boost the Ge-related technology.

Antiphospholipid syndrome in northwest Italy (APS Piedmont Cohort): demographic features, risk factors, clinical and laboratory profile

We report the experience from the Antiphospholipid Antibodies (aPL) Regional Consortium in northwest Italy, meant to support clinical research and foster collaboration among health professionals regarding the diagnosis and management of antiphospholipid syndrome (APS) patients. This cohort-study (APS Piedmont Cohort) was designed to register the clinical characteristics at inception and associated immunological manifestations at diagnosis (if any) of patients who strictly fulfilled the current criteria for APS, all recruited at the Piedmont and Valle d'Aosta regions. Clinical and laboratory data from 217 APS patients (171 with vascular events, 33 with pregnancy morbidity and 13 with both), from 16 centres within the geographical area were collected. Venous thrombosis was recorded in 45.6% of patients, arterial thrombosis in 35%, small-vessel thrombosis in 1.12% and mixed arterial and venous thrombosis in the remaining 19.4% of the cases. Pregnancy morbidity included 19 patients with unexplained fetal death beyond the 10th week of pregnancy, 17 with premature birth before the 34th week and 10 with three or more unexplained spontaneous abortions before the 10th week of gestation. This consortium represents an instrument by which to audit clinical practice, to provide counselling to local centres and to sustain future basic and clinical APS research.

Effects of anti-CD20 monoclonal antibody as a rescue treatment for ANCA-associated idiopathic systemic vasculitis with or without overt renal involvement

BACKGROUND

Cyclophosphamide (CYC) is thought to be the most effective treatment for antineutrophil cytoplasmatic antibody (ANCA)-associated idiopathic systemic vasculitis with severe organ or life threatening presentation. The key mechanism of action of CYC is suppression of the B lymphocyte activity. However, a considerable minority of patients either remains refractory to conventional therapy or experiences dose-limiting side effects.

METHODS

In the present study, rituximab (4 weekly doses of 375 mg/m2 and 2 more doses at 1-month interval) was intravenously administered as a rescue therapy to 7 patients (4 affected by idiopathic systemic microscopic polyangiitis, 2 by Wegener's granulomatosis, and 1 affected by Churg Strauss syndrome). The study group was made up of 3 women and 4 men, mean age 61.5 years (39-71), intolerant or refractory to more conventional therapy. Four patients had histologically confirmed paucimmune necrotizing glomerulonephritis.

RESULTS

Significant decreases were observed in levels of serum creatinine, proteinuria, erythrocyte sedimentation rate, C-reactive protein, and ANCA titers within the first 12 months of follow-up. Arthralgia and weakness rapidly disappeared in all patients. Four out of five patients reported a decrease in the degree of paresthesia, paralleled by an improvement in the electrodiagnostic parameters. A significant improvement was observed in both Birmingham Vasculitis Activity Score and Vasculitis Damage Index. Side effects were negligible.

CONCLUSION

In this sample of patients with idiopathic systemic vasculitis that was refractory or intolerant to conventional treatment, rituximab was found to be a safe and effective rescue therapy.
