RESUMO

AIMS: Low-risk status in pulmonary arterial hypertension (PAH) predicts better survival. The present study aimed to describe changes in risk status and treatment approaches over multiple clinical assessments in PAH, taking age and comorbidity burden into consideration. METHODS AND RESULTS: The study included incident patients from the Swedish PAH registry, diagnosed with PAH in 2008-2019. Group A (n = 340) were ≤75 years old with <3 comorbidities. Group B (n = 163) were >75 years old with ≥3 comorbidities. Assessments occurred at baseline, first-year (Y1) and third-year (Y3) follow-ups. The study used an explorative and descriptive approach. Group A: median age was 65 years, 70% were female, and 46% had no comorbidities at baseline. Baseline risk assessment yielded low (23%), intermediate (66%), and high risk (11%). Among patients at low, intermediate, or high risk at baseline, 51%, 18%, and 13%, respectively, were at low risk at Y3. At baseline, monotherapy was the most common therapy among low (68%) and intermediate groups (60%), while dual therapy was the most common among high risk (69%). In patients assessed as low, intermediate, or high risk at Y1, 66%, 12%, and 0% were at low risk at Y3, respectively. Of patients at intermediate or high risk at Y1, 35% received monotherapy and 13% received triple therapy. In low-risk patients at Y1, monotherapy (40%) and dual therapy (43%) were evenly distributed. Group B: median age was 77 years, 50% were female, and 44% had ≥3 comorbidities at baseline. At baseline, 8% were at low, 80% at intermediate, and 12% at high risk. Monotherapy was the most common therapy (62%) in Group B at baseline. Few patients maintained or reached low risk at follow-ups. CONCLUSIONS: Most patients with PAH did not meet low-risk criteria during the 3 year follow-up. The first year from diagnosis seems important in defining the longitudinal risk status.

RESUMO

Phosphodiesterase-5 inhibitors are commonly used in pulmonary arterial hypertension but, as suggested by the RESPITE study, phosphodiesterase-5 inhibitor therapy (mono-/combination) does not always have a satisfactory treatment effect. This study aimed to investigate the clinical course of pulmonary arterial hypertension patients not at treatment goal after at least 90 days of treatment with phosphodiesterase-5 inhibitors, alone or in combination with other pulmonary arterial hypertension therapies. The study included 106 incident patients from the Swedish Pulmonary Arterial Hypertension Registry, treated with phosphodiesterase-5 inhibitors for ≥90 days, who were not at a pre-specified treatment goal, i.e. in World Health Organisation functional class III, with 6-min walking distance 165-440 m, and N-terminal prohormone of brain natriuretic peptide >300 ng/L. Changes in World Health Organisation functional class, 6-min walking distance, N-terminal prohormone of brain natriuretic peptide, and risk group between index and follow-up were assessed. Of patients with complete follow-up data, (n = 53) 77% were on combination therapy and risk assessment yielded 98% at intermediate risk at index. At follow-up, 11 patients transitioned from World Health Organisation functional class III to World Health Organisation functional class II, the median (Q1; Q3) change in 6-min walking distance was 6 (-30; 42) meters and in N-terminal prohormone of brain natriuretic peptide 47 (-410; 603) ng/L, while 89% remained at an intermediate risk. Of those without complete follow-up data, 11 patients died and 2 underwent lung transplantation. In conclusion, pulmonary arterial hypertension patients treated with phosphodiesterase-5 inhibitors, as single or combination therapy and not achieving the pre-specified treatment goals after ≥90 days have an unfavourable clinical course.

RESUMO

OBJECTIVE: Mycophenolate mofetil (MMF) is an established therapy for systemic sclerosis (SSc), but its pharmacokinetics in this disease remains unexplored. We have investigated drug exposure in MMF-treated patients with SSc in relation to clinical features of the disease and common concomitant drugs. METHODS: This study was predefined to include 35 MMF-treated SSc patients who were using MMF at a fixed dose of 0.5, 1.0 or 1.5 g twice daily since at least 3 months. The 12-h drug exposure of the active MMF metabolite mycophenolic acid (MPA) was estimated by repeated analysis of plasma MPA over a 6-h period. This 12-h drug exposure was dose normalised to a daily intake of 3 g MMF (MPA_AUC3g) in order to compare subjects using MMF at different doses. Drug exposure was analysed in reference to the clinical characteristics including body weight, renal function, autoantibodies, intestinal dysbiosis, intestinal inflammation assessed by faecal (F)-calprotectin, intestinal symptoms assessed by the University of California Los Angeles Scleroderma Trial Consortium Gastrointestinal Tract Instrument 2.0 and concomitant drug usage including proton-pump inhibitors (PPI). RESULTS: Thirty-four out of 35 study participants completed the study. The mean daily MMF dose was 2.1 g. Drug exposure expressed as MPA_AUC3g varied up to 8-fold between patients (median 115, range 27-226 mg h/L). MPA_AUC3g was inversely related to body weight (rs = - 0.58, p < 0.001) and renal function (rs = - 0.34, p = 0.054). Anti-topoisomerase-1 antibodies and male sex were associated with lower MPA_AUC3g (87 vs 123 and 71 vs 141; p = 0.008 and p = 0.015, respectively). MPA_AUC3g was inversely related to the intestinal abundance of lactobacilli and to F-calprotectin (rs = - 0.54, p = 0.004; rs = - 0.36, p = 0.034), but not to gastrointestinal symptoms. MPA_AUC3g was inversely related to PPI usage (rs = - 0.45, p = 0.007). We found no association between MPA_AUC3g and disease subtype, disease duration or disease activity. CONCLUSION: MMF-treated SSc patients exhibit considerable inter-individual variation in drug exposure, and lower MPA levels were primarily found in PPI users with poor prognostic factors. Body weight, renal function, sex, serology, gastrointestinal manifestations and/or measuring individual MPA exposure should be considered when using MMF for SSc.

RESUMO

BACKGROUND: Depressive symptoms are common in rheumatic diseases and influence patients' quality of life. The Patient Health Questionnaire-9 (PHQ-9), which assesses symptoms of depression, is valid in English in patients with systemic sclerosis (SSc). However, the measurement properties of the PHQ-8 (short version of the PHQ-9) have not been evaluated in Swedish patients with SSc. OBJECTIVE: To investigate different aspects of validity and reliability of the PHQ-8 in Swedish (PHQ-8 Swe) for individuals with SSc. METHODS: A total of 101 patients with SSc participated. Content validity was evaluated via interviews of 11 patients and 10 health professionals. Construct validity, internal consistency test-retest reliability, and floor/ceiling effects were evaluated in 90 patients. RESULTS: Content validity was satisfactory, but some linguistic adjustments were made. Confirmatory factor analysis supported a better fit for a two-factor structure. Moderate-to-strong correlations were found between the PHQ-8 Swe and scleroderma HAQ including VAS (rs = 0.4-0.7); Multidimensional Assessment of Fatigue (rs = 0.7); RAND-36 subscales (rs = - 0.5 to - 0.8); and lung disease severity (Medsger scores) (rs = 0.4). There were weak correlations (rs = <0.4) between the PHQ-8 Swe and modified Rodnan skin score; and vascular, heart, and kidney disease severity. Cronbach's alpha was 0.85, corrected item-to-total correlations were >0.40, and the ICC for the total score was 0.83. No floor/ceiling effects were found. CONCLUSION: The PHQ-8 Swe has satisfactory content validity and sufficient reliability in patients with in majority limited SSc. It is more strongly associated with self-reported disability, pain, disease interferences with daily activities, fatigue, and quality of life than with disease severity, except for a moderate association with lung severity.

RESUMO

OBJECTIVE: To assess pulmonary function and Chronic Obstructive Pulmonary Disease (COPD) development over time in patients with primary Sjögren's Syndrome (pSS) and the association between pulmonary function, radiographic findings, respiratory symptoms and clinical features of pSS, taking cigarette consumption into account. METHODS: Forty patients with pSS (mean age 66 yrs, range 42-81 yrs, 39 women), previously participating in a cross-sectional study on pulmonary involvement in pSS, were re-assessed by pulmonary function tests after a mean follow-up time of six years. At follow-up, patients were also assessed by high-resolution computed tomography (HRCT) of the chest and for pSS disease activity, respiratory symptoms and cigarette consumption. RESULTS: Patients with pSS showed significantly decreased percentages of predicted total lung capacity (TLC), residual volume (RV), RV/ TLC ratio and diffusing capacity of the lungs for carbon monoxide (DL,CO), and an increased percentage of predicted forced expiratory volume in one second/vital capacity (FEV1/VC) ratio from baseline to follow-up. The proportion of COPD did not change significantly from baseline to follow-up (38% vs. 40%). Radiographic signs of bronchial involvement and interstitial lung disease were found in 38% of the patients, respectively. CONCLUSION: Both airway and pulmonary parenchymal disease were commonly found in pSS patients, with a co-existence of both an obstructive and a restrictive pulmonary function pattern, where the latter tended to deteriorate over time. COPD was still a common finding. Airway and pulmonary involvement may be underdiagnosed in pSS, why special attention to clinical assessment of pulmonary involvement in pSS patients is mandated.

RESUMO

Background: Beside the pulmonary vasoconstriction observed in pulmonary arterial hypertension (PAH), severe proliferative and antiapoptotic cellular phenotypes result in vascular remodelling. Many recent findings indicate similarities between PAH and tumour pathology. For instance, insulin-like growth factor (IGF)-1 signalling, which is known to promote tumour development, is implicated in PAH. Higher circulating IGF binding protein (IGFBP)-1 levels are associated with worse survival in PAH. The present study aimed to investigate the relationship between plasma levels of various tumour-related biomarkers and PAH. Methods: IGFBP-1, -2 and -7, along with other tumour-related biomarkers, were measured in plasma from 48 treatment-naïve PAH patients and 16 healthy controls, using proximity extension assays. Among the PAH patients, 33 were also studied at an early treatment follow-up. Results: Plasma IGFBP-1 (p < .003), IGFBP-2 (p < .001), IGFBP-7 (p < .008), vimentin (p < .001), carbonic anhydrase 9 (p < .001), S100A11 (p < .001), human epididymis protein 4 (p < .001) and folate receptor-α (p < .004) were elevated in PAH, compared to controls. IGFBP-1 exhibited the most interesting correlations to clinical parameters and was selected for further analyses. IGFBP-1 correlated specifically to N-terminal prohormone of brain natriuretic peptide (NT-proBNP) (r = 0.44, p < .002), mean right atrial pressure (r = 0.41, p < .004), venous oxygen saturation (r = -0.43, p < .003), cardiac index (r = -0.32, p < .03) and 6-minute walking distance (r = -0.29, p < .05). Plasma IGFBP-1 also correlated to risk scores based on the European Society of Cardiology/European Respiratory Society (ESC/ERS) PAH guidelines (r = 0.43, p < .003) and the REVEAL model (r = 0.46, p < .001). PAH patients with supra-median baseline IGFBP-1 levels showed a trend for worse overall survival than those with infra-median levels (p = .087). IGFBP-1 was unaltered between baseline and an early treatment follow-up. However, IGFBP-1 changes, between baseline and follow-up, correlated to changes in NT-proBNP (r = 0.48, p < .006). Conclusion: Plasma IGFBP-1 levels at PAH diagnosis show moderate association to NT-proBNP and hemodynamics as well as with ESC/ERS and REVEAL risk scores.

RESUMO

Objectives. To investigate if the pulmonary arterial hypertension (PAH) risk assessment tool presented in the 2015 ESC/ERS guidelines is valid for patients with chronic thromboembolic pulmonary hypertension (CTEPH) when taking pulmonary endarterectomy (PEA) into account. Design. Incident CTEPH patients registered in the Swedish PAH Registry (SPAHR) between 2008 and 2016 were included. Risk stratification performed at baseline and follow-up classified the patients as low-, intermediate-, or high-risk using the proposed ESC/ERS risk algorithm. Results. There were 250 CTEPH patients with median age (interquartile range) 70 (14) years, and 53% were male. Thirty-two percent underwent PEA within 5 (6) months. In a multivariable model adjusting for age, sex, and pharmacological treatment, patients with intermediate-risk or high-risk profiles at baseline displayed an increased mortality risk (Hazard Ratio [95% confidence interval]: 1.64 [0.69-3.90] and 5.39 [2.13-13.59], respectively) compared to those with a low-risk profile, whereas PEA was associated with better survival (0.38 [0.18-0.82]). Similar impact of risk profile and PEA was seen at follow-up. Conclusion. The ESC/ERS risk assessment tool identifies CTEPH patients with reduced survival. Furthermore, PEA improves survival markedly independently of risk group and age. Take home message: The ESC/ERS risk stratification for PAH predicts survival also in CTEPH patients, even when taking PEA into account.

RESUMO

Exhaled breath temperature has been suggested to reflect airway inflammation, and it would be plausible to measure the peripheral airway temperature as a correlate to peripheral airway inflammation. This study aims to explore the relative peripheral airway temperature in patients with asthma, chronic obstructive pulmonary disease (COPD) or systemic sclerosis (SSc) compared to healthy controls, and relate to lung function and exhaled nitric oxide. Sixty-five subjects (16 asthmatics, 18 COPD patients, 17 SSc patients and 14 healthy subjects) performed fractional exhaled breath temperature measurements using a novel device, fractional exhaled NO measurements, spirometry, impulse oscillometry, body plethysmography and CO-diffusion capacity test. A significant overall difference among all the patient groups was seen in both the Tmax (= peak values of the entire exhalation) and T3max (= peak value of the last fraction of the exhaled volume). A significant difference in T3/T1 ratio (= the ratio of peripheral versus central air temperature) was found between asthmatic subjects and those with COPD or SSc. In addition, T1max (= temperature in the central), T3max (= peripheral airways) and the T3/T1ratio related to several volumetric measurements (both in absolute values and as percent predicted), such as vital capacity, total lung capacity, forced expiratory volume in 1 s, and diffusion capacity. The temperature ratio of the peripheral versus central airways was lower in patients with COPD or SSc compared to asthmatics, who in turn presented similar levels as the controls. There was also a large overlap between the groups. Overall, the airway temperatures were related to absolute lung volumes, and specifically, the peripheral temperature was related to the gas diffusion capacity (% predicted), suggesting a link to the vascular component.

RESUMO

Tissue turnover, especially in the skin, is altered in systemic sclerosis (SSc), leading to tissue accumulation. The objective was to examine type III, IV, and VI collagens turnovers in SSc and investigate longitudinal alterations in relation to modified Rodnan Skin Score (mRSS). We included patients fulfilling the 2013 ACR/EULAR criteria for SSc (limited cutaneous [lcSSc, n = 20], diffuse cutaneous SSc [dcSSc, n = 23]) and healthy controls (HC, n = 10). Biomarkers of type III, IV, and VI collagens formation (PRO-C3, PRO-C4, PRO-C6) and degradation (C3M, C4M, C6M) were measured in serum. The fibrotic index of the individual collagens (FICol) were calculated. The fibrotic index of type III and VI collagens (FICol3 and FICol6) were increased in dcSSc compared to lcSSc (FICol3: 1.4 vs. 0.8, P = 0.0001; FICol6: 1.2 vs. 0.9, P = 0.03). The fibrotic index of type IV collagen (FICol4) was not different between the groups but was 1.5 times higher than HC (HC: 6.9, lcSSc 10.4, dcSSc: 10.5). Both FICol3 and FICol6 correlated with mRSS with rho's of 0.59 (P < 0.0001) and 0.35 (P = 0.04). Furthermore, FICol3 steadily decrease over the disease course. Examining collagen turnover and specific collagens could be beneficial in following patients' skin fibrosis and possibly identifying progressors.

RESUMO

Capillaroscopy is a non-invasive and safe tool which allows the evaluation of the morphology of the microcirculation. Since its recent incorporation in the 2013 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria for systemic sclerosis together with its assessed role to monitor disease progression, capillaroscopy became a 'mainstream' investigation for rheumatologists. Given its increasing use by a variety of physicians internationally both in daily practice to differentiate primary from secondary Raynaud's phenomenon, as well as in research context to predict disease progression and monitor treatment effects, standardisation in capillaroscopic image acquisition and analysis seems paramount. To step forward to this need, experts in the field of capillaroscopy/microcirculation provide in this very consensus paper their view on image acquisition and analysis, different capillaroscopic techniques, normal and abnormal capillaroscopic characteristics and their meaning, scoring systems and reliability of image acquisition and interpretation.

RESUMO

Systemic sclerosis is an autoimmune systemic disease with an annual incidence in Sweden of only 20 cases per million and a standardised mortality rate of 3-4. Disease onset is usually preceded by a period with Raynaud's phenomenon, combined with structurally abnormal nailbed capillaries and accompanied by presence of scleroderma related autoantibodies. The presenting symptoms are skin thickness, puffy fingers, digital ulcers, dysphagia, joint stiffness and pain, and pruritus. Optimal management involves a number of specialists including allied health professionals. Early recognition, diagnosis and treatment are important. The dominating causes of death are cardiopulmonary.

RESUMO

BACKGROUND: Impaired myocardial deformation has been sporadically described in cardiac asymptomatic systemic sclerosis (SSc). We aimed to study myocardial deformation indices in cardiac asymptomatic SSc patients using cardiac magnetic resonance feature tracking (CMR-FT) and correlate these findings to the phenotypic and autoimmune background. METHODS: Fifty-four cardiac asymptomatic SSc patients (44 females, 56±13 years), with normal routine cardiac assessment and CMR evaluation, including cine and late gadolinium enhancement (LGE) images, were included. SSc patients were compared to 21 sex- and age- matched healthy controls (17 females; 54±19 years). For CMR-FT analysis, a mid-ventricular slice for LV peak systolic radial and circumferential strain and a 4-chamber view for LV/RV peak systolic longitudinal strain were used. RESULTS: Twenty-four patients had diffuse cutaneous SSc and 30 limited cutaneous SSc. Thirteen patients had digital ulcers. Median disease duration was 3.6 years. LV ejection fraction was higher in SSc patients compared to controls (62±6% vs. 59±5%, p = 0.01). Four patients had no LGE examination; in the remaining patients LGE was absent in 74%, while 18% had RV insertion fibrosis and 8% evidence of subendocardial infarction. LV longitudinal strain differed in those with insertion fibrosis (-18.0%) and infarction (-16.7%) compared to no fibrosis (-20.3%, p = 0.04). Patients with SSc had lower RV longitudinal strain and strain rate compared to controls (p<0.001 and p = 0.01, respectively). All other strain and strain rate measurements were non-significant between patients and controls. CONCLUSIONS: In cardiac asymptomatic SSc patients with normal routine functional indices, CMR-FT identifies subclinical presence of insertion fibrosis and/or myocardial infarction by impaired LV longitudinal strain. RV derived longitudinal indices were impaired in the patient group. CMR FT indices did not correlate to the patients' phenotypic and autoimmune features.

RESUMO

For patients living with chronic conditions, the daily life will change due to symptoms, drug treatment, and psychosocial factors caused by the disease. Our studies show that Swedish patients with PAH or CTEPH are satisfied with the information they have received, but still have a wish for more. Therefore, it is important to repeat the information on a regular basis and to make sure that patients have understood and remember the messages. In order to increase the knowledge about their disease, improve compliance with treatment and quality of life, patients and next of kin should continuously be informed by the multidisciplinary team at the PAH/CTEPH-specialist care centers.

RESUMO

Serum levels of cartilage oligomeric matrix protein (COMP) has been presented as a biomarker of liver fibrosis in several cross-sectional studies. COMP is also an essential mediator in carcinoma development and has also been associated with hepatocellular carcinoma. We present a prospective analysis of this biomarker in 38 patients with chronic hepatitis C who were subject to eradication therapy with direct acting antivirals. We confirm previous studies associating COMP elevation with liver cirrhosis. We also show how viral levels are correlated with COMP at baseline. In our prospective analysis, we report that successful eradication of hepatitis C results in improvement in liver stiffness and laboratory liver function tests at 1 year follow-up. In contrast, median COMP-levels remain unchanged during the study period. We conclude that the biomarker potential of COMP in the prospective evaluation of liver diseases, remains to be elucidated.

RESUMO

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)>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<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.

RESUMO

Introduction: Spouses play a crucial role, both physically and psychologically, for patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). Our aim was to investigate the spouse's experiences when living with a partner diagnosed with PAH or CTEPH. Methods: We used a qualitative interview study design based on open-ended questions analysed using qualitative content analysis. Results: 14 spouses were interviewed. Two categories that describe spouses' experiences of dealing with everyday life were identified: "Living in an insecure life situation" and "Providing and receiving information and support". The experiences reported by the spouses were that their life situation was insecure, and that they had challenges in providing and receiving information and support. Most spouses also wanted and felt a need to be more involved in the care. Conclusion: The spouses were only partly satisfied with their life situation. To support the spouse's participation, the PAH/CTEPH team should encourage the patient to bring their spouse along, and offer them the opportunity to participate in the contacts with healthcare and provide information on an individual family perspective.

RESUMO

PURPOSE: Patients with pulmonary arterial hypertension (PAH) due to systemic sclerosis (SSc) have high mortality. Left ventricular (LV) peak global longitudinal strain (GLS) is decreased in SSc. It is unknown whether low GLS is due to SSc or PAH. Therefore, our primary aim was to evaluate both LV and right ventricular free wall GLS (RVFW GLS) in SSc, with and without PAH, using cardiac magnetic resonance with feature tracking. Secondary aim was to relate GLS to invasive mean pulmonary arterial pressure (mPAP) and pulmonary vascular resistance (PVR). METHODS: Thirty-eight patients with SSc, 19 patients with SSc-PAH and 19 healthy controls for comparison, were included. Endocardial and epicardial borders were delineated in cine images (short-axis stack and three long-axis views) for volumetric and strain calculations. RESULTS: Systemic sclerosis-PAH had lower LV and RVFW GLS than SSc (LV: P = 0·01, RV: P<0·001) and controls (LV: P = 0·02; RV: P<0·001), with no difference between SSc and controls. LV strain correlated with mPAP (R = 0·42, P = 0·03) and PVR (R = 0·52, P = 0·006). RVFW GLS correlated with mPAP (R = 0·68, P<0·001) and PVR (R = 0·59, P = 0·001). ROC curves for predicting PAH had AUC 0·73 for LV strain (P = 0·003) and 0·86 for RVFW GLS (P<0·001). CONCLUSIONS: Lower GLS is mainly determined by increased pulmonary pressure and not by SSc per se. Low LV and RVFW GLS are indicative of increased mPAP and PVR, which opens for improved non-invasive methods to select patients eligible for right heart catheterization and to monitor the effects of PAH therapy.
