ABSTRACT
OBJECTIVE: Systemic sclerosis (SSc) is an orphan disease that can lead to severe involvement of the gastrointestinal tract with a significant impact on patients' quality of life (QoL). The Mediterranean diet (MD) was consistently demonstrated to have beneficial effects on chronic diseases based on biological bases. We aimed to evaluate the adherence to the MD of Italian patients with SSc to preliminarily assess its association with gastrointestinal symptoms and other disease features, mood, and QoL. METHODS: In this cross-sectional study, adherence to the MD was measured in 387 patients from four SSc Italian referral centers through the 14-item Mediterranean Diet Adherence Screener (14-MEDAS) questionnaire. We also registered patients' reported outcomes related to the QoL and mood. RESULTS: Overall, an optimal adherence to MD was observed in 14.7% of patients with SSc, a moderate adherence in 71.3%, and a low adherence in 14.0%. In univariate analysis, poor adherence to the MD was associated with a more prominent depressive mood, time missed at work, and perception of more severe Raynaud's phenomenon and digital ulcers, whereas the 14-MEDAS score inversely correlated with depression score and reflux. CONCLUSION: In our cohort of patients with SSc, overall adherence to MD was moderate. Patients with lower adherence to MD also reported worse outcomes related to QoL and mood. Administration of the 14-MEDAS could be a reasonable choice to assess adherence to the MD in patients with SSc. Future initiatives to study the role of MD in the management of patients with SSc are warranted.
ABSTRACT
OBJECTIVES: Myocarditis is an overlooked manifestation of anti-synthetase syndrome (ASS). Our study describes the clinical and instrumental features of ASS-myocarditis and evaluates the diagnostic performance of cardiac magnetic resonance (CMR) with mapping techniques. METHODS: Data from ASS-patients were retrospectively analyzed. CMR data of patients diagnosed with myocarditis, including late gadolinium enhancement (LGE), T2-ratio, T1-mapping, extra-cellular volume (ECV) and T2-mapping, were reviewed. Myocarditis was defined by the presence of symptoms of heart involvement with increased high-sensitive troponin T (hs-TnT) and/or NT-proBNP and at least an instrumental abnormality. Clinical features of ASS patients with and without myocarditis were compared. A p value<0.05 was considered. RESULTS: Among a cohort of 43 ASS-patients (median age 58[48.0-66.0] years; females 74.4%; anti-Jo1 53.5%), 13(30%) were diagnosed with myocarditis. In 54% of patients, myocarditis was diagnosed at clinical onset. All ASS-myocarditis patients had at least one CMR abnormality: increased ECV in all cases, presence of LGE, increased T1 and T2-mapping in 91%. The 2009-Lake Louis criteria (LLC) were satisfied by 6 patients, the 2018-LLC by 10. With the updated LLC, the sensitivity for myocarditis improved from 54.6% to 91.0%. ASS-patients with myocarditis were more frequently males(53% vs 13%;p=0.009) with fever(69% vs 17%;p=0.001), and had higher hs-TnT (88.0[23.55-311.5] vs 9.80[5.0-23.0]ng/L; p < 0.001), NT-proBNP(525.5[243.5-1575.25] vs 59.0[32.0-165.5;p=0.013]pg/ml;p=0.013) and C-reactive protein(CRP)(7.0[1.7-15.75] vs 1.85[0.5-2.86]mg/L;p=0.011) compared to those without myocarditis. CONCLUSION: In ASS, myocarditis is frequent, even at clinical onset. ASS-patients with myocarditis frequently presented with fever and increased CRP, suggesting the existence of an inflammatory phenotype. The use of novel CMR mapping techniques may increase the diagnostic sensitivity for myocarditis in ASS.
ABSTRACT
Primary heart involvement is frequent in systemic sclerosis, even though often sub-clinical, and includes cardiac abnormalities that are predominantly attributable to systemic sclerosis rather than other causes and/or complications. A timely diagnosis is crucial to promptly start the appropriate therapy and to prevent the potential life-threatening early and late complications. There is little evidence on how to best manage systemic sclerosis-primary heart involvement as no specific treatment recommendations for heart disease are available, and a shared treatment approach is still lacking. The objective of this review is to summarize the state of the art of current literature and the overall management strategies and therapeutic approaches for systemic sclerosis-primary heart involvement. Novel insights into pathogenic mechanisms of systemic sclerosis-primary heart involvement are presented to facilitate the comprehension of therapeutic targets and novel treatment strategies.
ABSTRACT
OBJECTIVES: Myocarditis in SSc is associated with a poor prognosis. Cardiac magnetic resonance (CMR) is the non-invasive diagnostic modality of choice for SSc myocarditis. Our study investigates the performance of the mapping techniques included in the revised Lake Louise criteria (LLC) for the identification of SSc myocarditis. METHODS: CMR data (right and left ventricular function and morphology, early and late gadolinium enhancement [LGE], T2 ratio, and T1 mapping, extracellular volume [ECV] and T2 mapping) of SSc patients diagnosed with myocarditis were reviewed. Myocarditis was defined by the presence of symptoms of SSc heart involvement with increased high-sensitive troponin T (hs-TnT) and/or NT-proBNP and at least an abnormality at 24 h ECG Holter and/or echocardiography and/or CMR. A P-value < 0.05 was considered as statistically significant. RESULTS: Nineteen patients (median age 54 [46-70] years; females 78.9%; diffuse SSc 52.6%; anti-Scl70+ 52.6%) were identified: 11 (57.9%) had echocardiographic, and 8 (42.8%) 24 h ECG Holter abnormalities. All patients had at least one CMR abnormality: LGE in 18 (94.7%), increased ECV in 10 (52.6%) and T2 mapping >50 ms in 15 (78.9%). Median T1 and T2 mapping were 1085 [1069-1110] ms and 53.1 [52-54] ms, respectively. T1 mapping directly correlated with NT-proBNP (r = 0.620; P = 0.005), ESR (r = 0.601; P = 0.008), CRP (r = 0.685; P = 0.001) and skin score (r = 0.507; P = 0.027); ECV correlated with NT-proBNP serum levels (r = 0.702; P = 0.001). No correlations emerged between T2 mapping and other parameters. Ten patients satisfied the 2009 LLC, 17 the 2018 LLC. With the new criteria including T2 mapping, the sensitivity improved from 52.6% to 89.5%. CONCLUSION: The CMR mapping techniques improve the sensitivity to detect myocardial inflammation in patients with SSc heart involvement. The evaluation of T2 mapping increases diagnostic accuracy for the recognition of myocardial inflammation in SSc.
