Patologia cardiovasculară la pacienţii cu artrită reumatoidă: epidemiologie, patogeneză şi prevenire

Conferinţa naţională în medicina internă din Republica Moldova cu participare internaţională, 19-20 mai 2011, Chişinău, Republica MoldovaArtrita reumatoidă (AR) este asociată cu un risc sporit de evenimente cardiovasculare (CV). Patologia CV, inclusiv infarctul miocardic şi ictusul reprezintă cauzele majore ale mortalităţii printre pacienţii cu AR. De asemenea, la această populaţie există un risc sporit de infarct miocardic nonfatal şi de insuficienţă cardiacă. S-a estimat că mortalitatea cauzată de CV la pacienţii cu AR este de 2-5 ori mai înaltă decât în populaţia generală. Această creştere este remarcată în primii 8-10 ani de la debutul simptomelor de AR. La fel, ultimele studii au demonstrat că AR este un factor de risc independent pentru patologia CV, la fel de important ca şi diabetul zaharat. Mecanismele care stau la baza acestei incidenţe sporite şi prezic severitatea patologiei CV la pacienţii cu AR nu sunt pe deplin înţelese. Ateroscleroza este o patologie cronică inflamatorie, iar inflamaţia sistemică foarte importantă, asociată cu AR, exercită atât efecte directe asupra endoteliului vascular, cât şi indirect potenţează procesul aterosclerotic. Această stare patologică este cunoscută ca „ateroscleroză potenţată prin inflamaţie cronică”. Se presupune că activarea celulelor endoteliale şi disfuncţia endotelială ulterioară constituie mecanismul de legătură dintre AR timpurie şi ateroscleroză. Profilul citochinic şi interacţiunile proteinelor de adeziune sunt foarte similare în inflamaţia sinovială în caz de AR şi ateroscleroză. S-a demonstrat că câţiva indici ai inflamaţiei corelează cu incidenţa patologiei CV la pacienţii cu AR. Astfel, a fost demonstrat că viteza înaltă de sedimentare a hematiilor este un factor predictiv la aceşti bolnavi. Alte studii au revelat că viteza de sedimentare a hematiilor este un prezicător al mortalităţii CV. Proteina C-reactivă este un factor predictiv recunoscut pentru evenimente CV atât la bărbaţi, cât şi la femei. Această legătură a fost confirmată la pacienţii cu AR. Rolul dereglărilor imune în apariţia unui risc CV sporit a fost sugerat în baza unei mortalităţi semnificativ ridicate printre bolnavii cu AR cu factor reumatoid pozitiv sau anticorpi antinucleari. Din câte se cunoaşte, pacienţii cu test pozitiv la factorul reumatoid sunt expuşi unui risc de maladie mai activă asociată, de regulă, cu o inflamaţie cronică mai severă. Rolul factorilor tradiţionali de risc CV la pacienţii cu AR în dezvoltarea aterosclerozei şi a sechelelor acesteia rămâne neelucidat, iar influenţa lor trebuie analizată în contextul inflamaţiei sistemice. Pentru a preveni patologia CV la pacienţii cu AR sunt necesare măsuri complexe. Controlul optim al factorilor tradiţionali de risc CV este indispensabil, dar crucială este supresiunea inflamaţiei sistemice. S-a demonstrat că tratamentul cu metotrexat reduce riscul de mortalitate CV. Există, la fel, dovezi ale rolului agenţilor anti-TNF-alfa în prevenirea aterosclerozei, iar terapia cu agenţi anti-TNF-alfa inhibă câteva etape de dezvoltare a aterosclerozei. Efectele benefice ale acestei terapii asupra incidenţei evenimentelor CV, precum şi a mortalităţii sunt demonstrate doar de unele studii observaţionale. Sunt necesare deci cercetări privind reducerea riscului CV la utilizarea agenţilor anti-TNF-alfa la pacienţii cu AR

Progressive skin fibrosis is associated with a decline in lung function and worse survival in patients with diffuse cutaneous systemic sclerosis in the European Scleroderma Trials and Research (EUSTAR) cohort.

Objectives To determine whether progressive skin fibrosis is associated with visceral organ progression and mortality during follow-up in patients with diffuse cutaneous systemic sclerosis (dcSSc). Methods We evaluated patients from the European Scleroderma Trials and Research database with dcSSc, baseline modified Rodnan skin score (mRSS) ≥7, valid mRSS at 12±3 months after baseline and ≥1 annual follow-up visit. Progressive skin fibrosis was defined as an increase in mRSS >5 and ≥25% from baseline to 12±3 months. Outcomes were pulmonary, cardiovascular and renal progression, and all-cause death. Associations between skin progression and outcomes were evaluated by Kaplan-Meier survival analysis and multivariable Cox regression. Results Of 1021 included patients, 78 (7.6%) had progressive skin fibrosis (skin progressors). Median follow-up was 3.4 years. Survival analyses indicated that skin progressors had a significantly higher probability of FVC decline ≥10% (53.6% vs 34.4%; p<0.001) and all-cause death (15.4% vs 7.3%; p=0.003) than non-progressors. These significant associations were also found in subgroup analyses of patients with either low baseline mRSS (≤22/51) or short disease duration (≤15 months). In multivariable analyses, skin progression within 1 year was independently associated with FVC decline ≥10% (HR 1.79, 95% CI 1.20 to 2.65) and all-cause death (HR 2.58, 95% CI 1.31 to 5.09). Conclusions Progressive skin fibrosis within 1 year is associated with decline in lung function and worse survival in dcSSc during follow-up. These results confirm mRSS as a surrogate marker in dcSSc, which will be helpful for cohort enrichment in future trials and risk stratification in clinical practice

Predictors of disease worsening defined by progression of organ damage in diffuse systemic sclerosis: a European Scleroderma Trials and Research (EUSTAR) analysis

OBJECTIVES: Mortality and worsening of organ function are desirable endpoints for clinical trials in systemic sclerosis (SSc). The aim of this study was to identify factors that allow enrichment of patients with these endpoints, in a population of patients from the European Scleroderma Trials and Research group database. METHODS: Inclusion criteria were diagnosis of diffuse SSc and follow-up over 12±3 months. Disease worsening/organ progression was fulfilled if any of the following events occurred: new renal crisis; decrease of lung or heart function; new echocardiography-suspected pulmonary hypertension or death. In total, 42 clinical parameters were chosen as predictors for the analysis by using (1) imputation of missing data on the basis of multivariate imputation and (2) least absolute shrinkage and selection operator regression. RESULTS: Of 1451 patients meeting the inclusion criteria, 706 had complete data on outcome parameters and were included in the analysis. Of the 42 outcome predictors, eight remained in the final regression model. There was substantial evidence for a strong association between disease progression and age, active digital ulcer (DU), lung fibrosis, muscle weakness and elevated C-reactive protein (CRP) level. Active DU, CRP elevation, lung fibrosis and muscle weakness were also associated with a significantly shorter time to disease progression. A bootstrap validation step with 10 000 repetitions successfully validated the model. CONCLUSIONS: The use of the predictive factors presented here could enable cohort enrichment with patients at risk for overall disease worsening in SSc clinical trials.status: publishe

Outcomes of patients with systemic sclerosis treated with rituximab in contemporary practice: a prospective cohort study.

Objective To assess the safety and efficacy of rituximab in systemic sclerosis (SSc) in clinical practice. Methods We performed a prospective study including patients with SSc from the European Scleroderma Trials and Research (EUSTAR) network treated with rituximab and matched with untreated patients with SSc. The main outcomes measures were adverse events, skin fibrosis improvement, lung fibrosis worsening and steroids use among propensity score-matched patients treated or not with rituximab. Results 254 patients were treated with rituximab, in 58% for lung and in 32% for skin involvement. After a median follow-up of 2 years, about 70% of the patients had no side effect. Comparison of treated patients with 9575 propensity-score matched patients showed that patients treated with rituximab were more likely to have skin fibrosis improvement (22.7 vs 14.03 events per 100 person-years; OR: 2.79 [1.47-5.32]; p=0.002). Treated patients did not have significantly different rates of decrease in forced vital capacity (FVC)&gt;10% (OR: 1.03 [0.55-1.94]; p=0.93) nor in carbon monoxide diffusing capacity (DLCO) decrease. Patients having received rituximab were more prone to stop or decrease steroids (OR: 2.34 [1.56-3.53], p&lt;0.0001). Patients treated concomitantly with mycophenolate mofetil had a trend for better outcomes as compared with patients receiving rituximab alone (delta FVC: 5.22 [0.83-9.62]; p=0.019 as compared with controls vs 3 [0.66-5.35]; p=0.012). Conclusion Rituximab use was associated with a good safety profile in this large SSc-cohort. Significant change was observed on skin fibrosis, but not on lung. However, the limitation is the observational design. The potential stabilisation of lung fibrosis by rituximab has to be addressed by a randomised trial

Phenotypes determined by cluster analysis and their survival in the prospective european scleroderma trials and research cohort of patients with systemic sclerosis

Systemic sclerosis (SSc) is a heterogeneous connective tissue disease that is typically subdivided into limited cutaneous SSc (lcSSc) and diffuse cutaneous SSc (dcSSc) depending on the extent of skin involvement. This subclassification may not capture the entire variability of clinical phenotypes. The European Scleroderma Trials and Research (EUSTAR) database includes data on a prospective cohort of SSc patients from 122 European referral centers. This study was undertaken to perform a cluster analysis of EUSTAR data to distinguish and characterize homogeneous phenotypes without any a priori assumptions, and to examine survival among the clusters obtained
