RESUMO

Chronic COVID syndrome is characterized by chronic fatigue, myalgia, depression and sleep disturbances, similar to chronic fatigue syndrome (CFS) and fibromyalgia syndrome. Implementations of mitochondrial nutrients (MNs) with diet are important for the clinical effects antioxidant. We examined if use of an association of coenzyme Q10 and alpha lipoic acid (Requpero®) could reduce chronic covid symptoms. The Requpero study is a prospective observational study in which 174 patients, who had developed chronic-covid syndrome, were divided in two groups: The first one (116 patients) received coenzyme Q10 + alpha lipoic acid, and the second one (58 patients) did not receive any treatment. Primary outcome was reduction in Fatigue Severity Scale (FSS) in treatment group compared with control group. complete FSS response was reached most frequently in treatment group than in control group. A FSS complete response was reached in 62 (53.5%) patients in treatment group and in two (3.5%) patients in control group. A reduction in FSS core < 20% from baseline at T1 (non-response) was observed in 11 patients in the treatment group (9.5%) and in 15 patients in the control group (25.9%) (p < 0.0001). To date, this is the first study that tests the efficacy of coenzyme Q10 and alpha lipoic acid in chronic Covid syndrome. Primary and secondary outcomes were met. These results have to be confirmed through a double blind placebo controlled trial of longer duration.

RESUMO

BACKGROUND: Identification of predictors of clinical response to certolizumab-pegol (certolizumab) may aid the decision-making process for treating patients with rheumatoid arthritis (RA), spondyloarthritis (SpA), and psoriatic arthritis (PsA). OBJECTIVE: The aim of our study was to evaluate the effectiveness of certolizumab and identify any predictors of favorable outcome in patients with RA, PsA, or SpA. METHODS: We studied 355 RA, SpA, and PsA patients starting treatment with certolizumab. Endpoints of the study were drug survival and identification of predictors of clinical outcome. Drug retention was analyzed via the Kaplan-Meier method, and hazard ratios (HRs) were estimated using Cox regression models. RESULTS: Of 355 certolizumab initiators, 178 had RA, 94 had PsA, and 83 had SpA. Biologic-naïve RA patients had significantly higher survival rates (73.3%) than switchers taking certolizumab as a second-line (49.0%) or third- or next-line biologic agent (51.2%; p = 0.0001). Instead, PsA and SpA patients showed similar drug retention rates regardless of the line of treatment. A significant clinical improvement from baseline was seen at 3 months for RA (28 joint-Disease Activity Score [DAS28]; p = 0.001), PsA (Disease Activity Index for PsA [DAPSA]; p = 0.001), and SpA (Bath Ankylosing Disease Index; p = 0.01). Biologic-naïve patients had the lowest HR (0.31; p = 0.001) of discontinuing certolizumab for RA, and the highest HR (7.94; p = 0.01) of achieving minimal disease activity (MDA) for PsA. For PsA, a predictor of late MDA was the achievement of low/remission DAPSA at 3 months, and 3-month low/remission DAS28 predicted late remission for RA. CONCLUSIONS: Our study revealed that the best predictor of certolizumab effectiveness in unselected patients with RA, PsA, or SpA was a biologic-naïve status and achievement of an early response within 3 months.

RESUMO

OBJECTIVES: To assess the drug survival of golimumab, and predictors thereof, in patients affected with rheumatoid arthritis (RA), spondyloarthritis (SpA), and psoriatic arthritis (PsA) in a prospective observational cohort. METHODS: This is a non-interventional, longitudinal study on RA, SpA, and PsA patients starting treatment with golimumab. Endpoints were the 2 years persistence rate of golimumab and predictors of therapy discontinuation. Drug retention was analyzed using Kaplan-Meier and Cox models. Hazard ratios (HR) of golimumab discontinuation were estimated by Cox-regression hazard models. RESULTS: Of 416 patients starting golimumab, 171 biologic-naïve and 245 inadequate responders to prior biologic drugs, 88 had RA, 147 SpA, and 181 PsA. Global 2 years drug retention was 70.2%, with no different hazard of discontinuation among diseases or line of biologic treatment. The strongest predictor of golimumab discontinuation was female gender (HR = 1.95). Golimumab monotherapy was associated with higher risk drug interruption (HR = 1.67). Within SpA, predictors of golimumab discontinuation were female sex (HR = 4.19), and absence of extra-articular manifestations (HR = 4.60). In PsA, duration of disease was negatively associated to drug interruption (HR = 0.93), whereas golimumab monotherapy was positively (HR = 2.21) associated. Interestingly, failing to achieve a good EULAR response at 3 months was the only predictor of golimumab discontinuation for RA patients (HR = 3.03). CONCLUSIONS: This study provided evidence that golimumab has high retention rate in real-life settings. SpA male patients with extra-articular manifestations, PsA patients on co-therapy with DMARDs, and RA patients attaining an early clinical response had the highest probability to continue golimumab over 2 years.

RESUMO

OBJECTIVE: To assess the prevalence of good clinical response and remission in rheumatoid arthritis (RA) patients with longstanding disease treated with anti-tumor necrosis factor-alpha (TNF-alpha) drugs at outpatient clinics. METHODS: Retrospective national study of 14 academic tertiary referral rheumatology medical centers. RA patients with a Disease Activity Score (DAS28) > 3.2 were defined as having active disease and could start TNF-alpha blockers. All patients received one TNF-alpha blocker plus methotrexate (10-20 mg/wk). At the third month the patients were categorized as responders or nonresponders, based on improvement of at least 0.25 of the Health Assessment Questionnaire (HAQ). Those who had improved by at least 0.25 HAQ were analyzed for possible predictors of DAS28 remission at the sixth month. RESULTS: A total of 1257 patients started TNF-alpha blockers. Of these, 591 (46.7%) reached the sixth month with an improvement of HAQ of 0.25 at the third month. In the cohort of patients reaching HAQ of 0.25, DAS28 remission was seen in 24% of rheumatoid factor (RF)-positive and 36% of RF-negative patients (p = 0.03). Logistic regression analysis for predictors of remission identified age at baseline, HAQ < 1.63, and RF negativity as positive predictors of remission at 6 months along with sex (male). CONCLUSION: We show that only a minority of patients with longstanding RA achieve a good clinical response or remission at the outpatient community level. Predictors of remission identify characteristics commonly observed in subsets with less severe RA.

RESUMO

OBJECTIVE: . Systemic sclerosis (SSc) is characterized by excessive production of collagen and other components of the extracellular matrix (ECM) by fibroblasts. The ECM receptors, integrins and CD44 (hyaluronan receptor), play a key role in the homeostasis of connective tissue and may also have a role in the pathogenesis of fibrosis. We investigated the expression of integrins and CD44 on skin fibroblasts from patients with limited and diffuse SSc. METHODS: We studied 13 patients with SSc, 8 with limited SSc, and 5 with diffuse SSc, and 8 control subjects. Fibroblasts were isolated and cultured from biopsies taken from the lesional skin of the second finger of the left hand. Cell-surface expression of beta1, beta3, alpha1-alpha6, alphav integrins, and CD44 was evaluated by immunofluorescence and flow cytometry analysis. RESULTS: Fibroblasts from limited SSc showed significantly decreased expression of alpha2, alpha3, alpha4 integrins, while diffuse SSc fibroblasts had significantly reduced expression of alpha5, alphav integrins, and CD44. Diffuse SSc also had significantly increased expression of alpha6 integrin on fibroblasts. In controls, the expression of alpha4 and alpha5 correlated positively, while in limited and diffuse SSc it did not. CONCLUSION: This is the first study evaluating separately the expression of adhesion molecules on skin fibroblasts from limited and diffuse subsets of SSc. We detected a distinct pattern of expression with decrease of collagen and fibronectin receptors in limited SSc, and downregulation of fibronectin and hyaluronan receptors in diffuse SSc. These results suggest that changes of fibroblasts/ECM interactions and mechanisms underlying the pathogenesis of fibrosis in SSc may differ in the single subset of the disease.
