An immersive virtual reality exergame as a patient education approach in fibromyalgia: Pilot study
Get PDFBackground Immersive Virtual Reality (VR) has been applied in pain management for various conditions, but its use in fibromyalgia (FM) remains underexplored. While physical activity plays a role in treating FM, patients’ low tolerance often limits its effectiveness. After reviewing the literature on VR and games for FM, we designed a novel VR exergame to assist FM patients in performing physical activity, and evaluate its feasibility. Materials and Methods This pilot study involved three female subjects with FM and four healthy female volunteers. The main outcomes included qualitative assessments of exertion, pain levels, psychological states experienced during the VR session, but also device comfort. Results Improvements in perceived exertion and pain intensity were observed during the VR exergame session in comparison to pre-exergame levels, along with a reduction in depression, stress and anxiety levels while using the VR immersive system. Most participants experienced also increase of relaxation and positive emotions during the exergame. Only one participant was not able to complete all levels of the exergame due to musculoskeletal pain exacerbation; nevertheless, this patient reported an improvement in motivation and enjoyment during the gameplay. Many participants expressed a greater motivation to perform the exercises in the VR environment compared to traditional training methods. Conclusion The proposed VR exergame is a feasible system that might reduce depression, stress and anxiety, while boosting motivation and relaxation in both healthy and FM subjects. A calibration protocol is required to tailor the system to each user's pain levels and physical abilities
The impact of two different rituximab-based strategies in cryoglobulinaemic vasculitis secondary to Sjögren's disease: a monocentric cohort study
No full textObjectives: To compare two different rituximab (RTX)-based therapeutic approaches on vasculitic and lymphoproliferative-related disease activity and on non-Hodgkin lymphoma (NHL) development in a cohort of patients affected by cryoglobulinaemic vasculitis secondary to Sjögren's disease (Sjögren-CryoVasc). Methods: Three Sjögren-CryoVasc treatment groups were identified: 1) early RTX induction followed by maintenance; 2) late RTX induction with possible on-demand retreatment; 3) no RTX treatment. The following outcomes were evaluated: a) changes in cumulative ESSDAI, considering vasculitic-related and lymphoproliferative-related domains and changes in ESSDAI specific to each single vasculitic-related and lymphoproliferative-related domain; b) development of NHL; c) occurrence of persistent hypogammaglobulinemia associated with serious infections. Results: 13 Sjögren-CryoVasc patients were identified: 1) 5/13 treated earlier with RTX with subsequent maintenance; 2) 5/13 treated late with RTX with possible on-demand retreatment; 3) 3/13 not treated with RTX. The two RTX groups showed a decrease in the ESSDAI score with group 1 showing the most substantial reduction (p=0.028). Patients receiving RTX exhibited significant improvement in cutaneous, PNS, and articular vasculitic-related ESSDAI domains (p=0.007; p=0.006; p=0.03, respectively). By contrast RTX did not greatly affect the lymphoproliferative-related ESSDAI domains, even if an improvement was noted in the glandular and nodal domains for group 1 (p=0.03; p=0.03, respectively). No differences in NHL occurrence or safety concerns were observed among the groups. Conclusions: RTX is an effective and safe treatment to control Sjögren-CryoVasc disease activity with a greater impact when administered earlier with a maintenance regimen. RTX alone cannot, however, affect the possible evolution of Sjögren-CryoVasc into an overt NHL
Sjögren's syndrome: one year in review 2023
No full text: Primary Sjögren's syndrome (pSS) is a systemic autoimmune disorder characterised by the T-cell-mediated hyperactivation of B-cells and cytokine production. The condition may evolve from an asymptomatic, indolent course, with glandular involvement, to extra-glandular systemic manifestations up to lymphoma development. On tissue level, the typical feature is the lymphocytic infiltration of the salivary gland by B-, T- and antigen presenting cells, as mirrored by the diagnostic cornerstone role of minor salivary gland (MSG) biopsy. Recently, increasing research focused on the investigation of mechanisms underlying the complex pathogenesis of the disease and highlighted the multi-factorial nature of SS consisting of concomitant involvement of environmental, genetic, neuroendocrine and immune factors. In particular, many aspects have been investigated regarding genetic and epigenetics, the role of specific B- and T-cell phenotypes and the investigation of disease-specific biomarkers as predictors of disease development, activity, and lymphomagenesis. Surely, a deeper understanding of these multiple mechanisms may facilitate earlier diagnosis, enable subphenotyping of patients and open novel therapeutic possibilities to address the unmet needs of the disease in the upcoming years.In this review, following the others of this series, we will summarise the most recent literature on pSS pathogenesis and clinical features focusing in particular on new insights into pSS molecular stratification and therapeutic advances in the era of precision medicine
Clinical and histological features of patients with primary sjögren's syndrome and autoimmune thyroiditis. a national multicentre cross-sectional study
No full textObjectives: Primary Sjögren's syndrome (pSS) is frequently associated with autoimmune thyroiditis (AT). The aim of this study was to evaluate the prevalence of AT in a national cohort of pSS and to describe the clinical and histological phenotype of patients with pSS and associated AT. Methods: In this multicentre cross-sectional study, data from 2546 pSS were collected and the presence of AT was reported. In a subgroup, the histology of minor salivary glands was evaluated. Differences between pSS with and without AT were evaluated. Results: A concomitant pSS and AT was detected in 19.6% of cases. Patients with pSS and AT displayed a lower prevalence of lymphoma, male sex and disease-modifying anti-rheumatic drugs (DMARDs) use and a higher prevalence of fibromyalgia, coeliac disease and hypergammaglobulinaemia. Multivariable analysis confirmed a higher prevalence of fibromyalgia and coeliac disease and lower use of DMARDs. In a subgroup of patients (n=232), a significantly higher focus score and number of foci was detected in pSS without AT (n=169) as compared to pSS with AT (n=54). Conclusions: This is the largest study evaluating the coexistence of pSS and AT. We confirm a high association between pSS and AT and describe the presence of a different phenotype characterized by a higher rate of celiac disease and fibromyalgia. Although not significant, the lower prevalence of both lymphoma and intake of DMARDs, along with a significantly lower focus score and number of foci, possibly suggest a more favourable outcome in concomitant pSS and AT which further deserve future investigations
An interoperable web-based platform to support health surveillance against latent tuberculosis infection in health care workers and students: The evolution of CROSSWORD study protocol
Get PDFBackground: Tuberculosis (TB) prevention is a major goal in teaching hospital setting. Because of the possible progression or reactivation of latent disease, the screening of both health-care workers (HCWs) and students is an important issue in the TB control program. Objective: to deploy a web-based platform interoperating health surveillance systems from different hospitals to define models based on the highlighted risk factors to predict the occurrence of Latent Tuberculosis Infection (LTBI) and to define prevention strategies and interventions. Methods: This is a cross-sectional ambispective observational study without drug and device. The primary endpoint is the prevalence of LTBI. The secondary endpoint is the identification of possible risk factors of LTBI in a large cohort of HCWs and students. Conclusions: This study aims to enrich the primary prevention measures against TB, having a high socio-economic-health impact in high-risk populations (HCWs and students) through an interoperable digital approach based on data obtained in three large Italian teaching hospitals.

Dopamine Pathway and Parkinson's Risk Variants Are Associated with Levodopa-Induced Dyskinesia
Get PDFBackground: Levodopa-induced dyskinesia (LID) is a common adverse effect of levodopa, one of the main therapeutics used to treat the motor symptoms of Parkinson's disease (PD). Previous evidence suggests a connection between LID and a disruption of the dopaminergic system as well as genes implicated in PD, including GBA1 and LRRK2. Objectives: Our goal was to investigate the effects of genetic variants on risk and time to LID. Methods: We performed a genome-wide association study (GWAS) and analyses focused on GBA1 and LRRK2 variants. We also calculated polygenic risk scores (PRS) including risk variants for PD and variants in genes involved in the dopaminergic transmission pathway. To test the influence of genetics on LID risk we used logistic regression, and to examine its impact on time to LID we performed Cox regression including 1612 PD patients with and 3175 without LID. Results: We found that GBA1 variants were associated with LID risk (odds ratio [OR] = 1.65; 95% confidence interval [CI], 1.21-2.26; P = 0.0017) and LRRK2 variants with reduced time to LID onset (hazard ratio [HR] = 1.42; 95% CI, 1.09-1.84; P = 0.0098). The fourth quartile of the PD PRS was associated with increased LID risk (OR = 1.27; 95% CI, 1.03-1.56; P = 0.0210). The third and fourth dopamine pathway PRS quartiles were associated with a reduced time to development of LID (HR = 1.38; 95% CI, 1.07-1.79; P = 0.0128; HR = 1.38; 95% CI = 1.06-1.78; P = 0.0147). Conclusions: This study suggests that variants implicated in PD and in the dopaminergic transmission pathway play a role in the risk/time to develop LID. Further studies will be necessary to examine how these findings can inform clinical care. © 2024 The Author(s).

Clinical efficacy of SARS-CoV-2 Omicron-neutralizing antibodies in immunoglobulin preparations for the treatment of agammaglobulinemia in patients with primary antibody deficiency
Get PDFImmunocompromised individuals are at significantly elevated risk for severe courses of coronavirus disease 2019 (COVID-19). In addition to vaccination, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) neutralizing antibodies (nAbs) have been applied throughout the pandemic, with time of treatment onset and potency against the currently prevailing virus variant identified as relevant factors for medical benefit. Using data from the European Society for Immunodeficiencies (ESID) registry, the present study evaluated COVID-19 cases in three groups of patients with inborn errors of immunity (IEI; 981 agammaglobulinemia patients on immunoglobulin replacement therapy (IGRT); 8960 non-agammaglobulinemia patients on IGRT; 14 428 patients without IGRT), and the neutralizing capacity of 1100 immunoglobulin lots against SARS-CoV-2 (“Wuhan” and Omicron strains), throughout 3 years. From the first (2020/2021) to the second (2021/2022) cold season, i.e., during the virus drift to the more contagious Omicron variants, an increase in case numbers was recorded that was comparable (~2- to 3-fold) for all three study groups. During the same period, immunoglobulin lots showed a profound nAb increase against the archetypal SARS-CoV-2 strain, yet only low levels of Omicron nAbs. Notably, shortly before the third (2022/2023) cold season, Omicron-neutralizing capacity of released immunoglobulin lots had plateaued at high levels. From the second to the third cold season, COVID-19 cases dropped markedly. While a ~6-fold case reduction was recorded for the groups of non-agammaglobulinemia patients on IGRT and IEI patients not receiving IGRT, the decline was ~30-fold for the group of agammaglobulinemia patients on IGRT. These findings suggest a substantial COVID-19-protective effect of IGRT, at least for distinct groups of antibody-deficient patients.Peer reviewe
