ABSTRACT

BACKGROUND@#Disease activity indices (DAIs) including disease activity score 28 (DAS28), simplified disease activity index (SDAI), and clinical disease activity index (CDAI) have been widely used in clinical practice and research studies of rheumatoid arthritis (RA). The objective of our study was to evaluate the correlation and concordance among different DAIs in Chinese patients with RA.@*METHODS@#A cross-sectional study, including patients enrolled in the Chinese registry of rheumatoid arthritis from November 2016 to August 2018, was conducted. The correlations were evaluated using Spearman correlation coefficient and concordance with Bland-Altman plots, quadratic weighted kappa, and discordance rates in the crosstab. For other indices, the optimal cutoff points corresponding to SDAI remission were explored through receiver operating characteristic curve analysis.@*RESULTS@#A total of 30,501 patients were included, of whom 80.46% were women. Most individuals were with moderate disease activity or high disease activity. High correlations among DAS28-erythrocyte sedimentation rate (ESR) and DAS28-C-reactive protein (CRP), SDAI and CDAI were observed. Similarly, the weighted kappa value among the indices was high. In Bland-Altman plots, a positive difference between DAS28-ESR and DAS28-CRP was observed, with an absolute difference of >1.2 in 3079 (10.09%) patients. In crosstab, approximately 30% of the patients were classified into different groups. Concordance values between SDAI remission and the optimal cutoff points of DAS28-ESR, DAS28-CRP, and CDAI were 3.06, 2.37, and 3.20, respectively.@*CONCLUSIONS@#Although DAIs had high correlations and weighted kappa values, the discordance between DAIs was significant in Chinese patients with RA. The four DAIs are not interchangeable.

ABSTRACT

BACKGROUND@#Despite the recent advances in treatments for rheumatoid arthritis (RA), there are still unmet needs in disease outcomes. This study aimed to analyze the satisfaction with drug therapies for RA according to the levels of disease severity (patient-assessed) and proportions of treatment cost to household income.@*METHODS@#This was a subgroup study of a cross-sectional study in patients with RA and their physicians. The patients were subdivided into different subgroups based on their self-assessed severity of RA and on the proportions of treatment cost to household income (50%). The Treatment Satisfaction Questionnaire for Medication version II was used to assess patients' treatment satisfaction.@*RESULTS@#When considering all medications, effectiveness, convenience, and global satisfaction scores were lower in the severe and moderate RA subgroups than those in the mild and extremely mild RA subgroups (all P 50% subgroup (all P 50% subgroups (F = 12.646, P = 0.005). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 8.794, P = 0.032).@*CONCLUSION@#Higher disease severity and higher financial burden were associated with lower patient satisfaction.

ABSTRACT

<p><b>BACKGROUND</b>Approximately 15-20% cases of systemic lupus erythematosus (SLE) are diagnosed in children. There have been a few studies reporting the epidemiological data of pediatric-onset SLE (cSLE) in China, neither comparing the differences between cSLE and adult-onset SLE (aSLE). The aim of this study was to describe the impact of age of onset on clinical features and survival in cSLE patients in China based on the Chinese SLE Treatment and Research group (CSTAR) database.</p><p><b>METHODS</b>We made a prospective study of 225 cSLE patients (aged Results: The mean age of cSLE patients was 12.16 ± 2.92 years, with 187 (83.1%) females. Fever (P < 0.001) as well as mucocutaneous (P < 0.001) and renal (P = 0.006) disorders were found to be significantly more frequent in cSLE patients as initial symptoms, while muscle and joint lesions were significantly less common compared to aSLE subjects (P < 0.001). The cSLE patients were found to present more frequently with malar rash (P = 0.001; odds ratio [OR], 0.624; 95% confidence interval [CI], 0.470-0.829) but less frequently with arthritis (P < 0.001; OR, 2.013; 95% CI, 1.512-2.679) and serositis (P = 0.030; OR, 1.629; 95% CI, 1.053-2.520). There was no significant difference in SLE disease activity index scores between cSLE and aSLE groups (P = 0.478). Cox regression indicated that childhood onset was the risk factor for organ damage in lupus patients (hazard ratio 0.335 [0.170-0.658], P = 0.001). The survival curves between the cSLE and aSLE groups had no significant difference as determined by the log-rank test (0.557, P = 0.455).</p><p><b>CONCLUSIONS</b>cSLE in China has different clinical features and more inflammation than aSLE patients. Damage may be less in children and there is no difference in 5- year survival between cSLE and aSLE groups.</p>

ABSTRACT

<p><b>BACKGROUND</b>Myocarditis is an uncommon but serious manifestation of systemic lupus erythematosus (SLE). This study aimed to investigate clinical characteristics and outcomes of lupus myocarditis (LM) and to determine risk factors of LM in hospitalized Chinese patients with SLE.</p><p><b>METHODS</b>We conducted a retrospective case-control study. A total of 25 patients with LM from 2001 to 2012 were enrolled as the study group, and 100 patients with SLE but without LM were randomly pooled as the control group. Univariable analysis was performed using Chi-square tests for categorical variables, and the Student's t-test or Mann-Whitney U-test was performed for continuous variables according to the normality.</p><p><b>RESULTS</b>LM presented as the initial manifestation of SLE in 7 patients (28%) and occurred mostly at earlier stages compared to the controls (20.88 ± 35.73 vs. 44.08 ± 61.56 months, P = 0.008). Twenty-one patients (84%) experienced episodes of symptomatic heart failure. Echocardiography showed that 23 patients (92%) had decreased left ventricular ejection fraction (<50%) and all patients had wall motion abnormalities. A high SLE Disease Activity Index was the independent risk factor in the development of LM (odds ratio = 1.322, P < 0.001). With aggressive immunosuppressive therapies, most patients achieved satisfactory outcome. The in-hospital mortality was not significantly higher in the LM group than in the controls (4% vs. 2%,P = 0.491).</p><p><b>CONCLUSIONS</b>LM could result in cardiac dysfunction and even sudden death. High SLE disease activity might potentially predict the occurrence of LM at the early stage of SLE. Characteristic echocardiographic findings could confirm the diagnosis of LM. Early aggressive immunosuppressive therapy could improve the cardiac outcome of LM.</p>

ABSTRACT

ObjectiveThe purpose of this study was to assess the efficacy,safety and optimal dose of tacrolimus monotherapy in patients with refractory lupus nephritis(LN) who were resistant to cyclophosphamide(CYC).MethodsA total of 14 LN patients (2 men and 12 women) with persistent proteinuria who were resistant to CYC treatment more than 8 g for half a year were enrolled.Tacrolimus was initiated at 2 mg/d (patient weight<60 kg) or 3 mg/d(patient weight≥60 kg) which was administered in two divided doses.Prospective data on daily proteinuria,serum album level and serologic lupus activity were collected and followed for 6 months.ANOVA and Pearson correlation analysis were used for statistical analysis.Results Mean age at baseline was(30±9) years.Mean urinary protein decreased significantly from(6.2±5.1) g at baseline to (1.1±0.9) g at 6 months (F=16.21,P<0.01).Mean serum album level increased significantly from (27.9±9.7) g/L at baseline to(37.8±2.2) g/L at 6 months(F=16.71,P<0.01 ).Complete or partial response was observed in 86% of patients receiving tacrolimus therapy.The effective dosage in this study was 0.03-0.06mg·kg-1·d-1 of the patients who had complete response or partial response to tacrolimus.The tacrolimus level in partially and completely responding patients was less than 3 ng/ml.There was no significant difference among blood tacrolimus levels of complete,partial,and no response patients [(1.6-±0.4),(2.0±0.6) and (22±1.1) ng/nl],respectively).No definite correlation was found between efficacy and tacrolimus level.Tacrolimus was well tolerated at current dose,besides one with new onset hypertension and one with alopecia.ConclusionOur results suggest that tacrolimus at low dosage and serum level is potentially effective and safe for the treatment of patients with LN and persistent proteinuria resistant to CYC.The optimal dosage of tacrolimus for LN may be 0.03-0.06 mg·kg-1·d-1.

ABSTRACT

We describe a case of systemic sclerosis (SSc) complicated with portal hypertensive ascites which did not improve with diuretics and ascitic drainage. When corticosteroid added, her ascites diminished dramatically. Though portal hypertension can be imputed to other causes, such as polycystic liver in this case, it can occur in limited SSc with positive anti-centromere antibody and respond to corticosteroid treatment.

ABSTRACT

<p><b>BACKGROUND</b>Hemodynamic evaluation is crucial for the management of patients with pulmonary hypertention. Clinicians often prefer a rapid and non-invasive method. This study aimed to examine the feasibility of transthoracic echocardiography for the measurements of hemodynamic parameters in patients with pulmonary hypertension.</p><p><b>METHODS</b>A prospective single-center study was conducted among 42 patients with pulmonary hypertension caused by different diseases. Transthoracic echocardiography and right-heart catheterization were performed within 24 hours. Pulmonary artery systolic, diastolic and mean pressure (PASP, PADP and PAMP), cardiac output (CO), and pulmonary capillary wedge pressure (PCWP) were measured by both methods. A linear correlation and a Bland-Altman analysis were performed to compare the two groups of hemodynamic parameters.</p><p><b>RESULTS</b>A good correlation was found between invasive and non-invasive measurements for PASP (r = 0.96), PADP (r = 0.85), PAMP (r = 0.88), CO (r = 0.82), and PCWP (r = 0.81). Further agreement analysis done by the Bland-Altman method showed that bias and a 95% confidence interval for PASP, PADP, and CO were clinically acceptable while great discrepancies existed for PAMP and PCWP.</p><p><b>CONCLUSIONS</b>The non-invasive measurements by PASP, PADP, and CO in patients with pulmonary hypertension correlate well with the invasive determinations. Transthoracic echocardiography (TTE) was inappropriate for estimating PCWP and PAMP.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the prevalence of anti-endothelial cell antibodies (AECAs) in the sera of connective tissue diseases (CTD) patients with pulmonary arterial hypertension (PAH) and its correlation with clinical manifestations.</p><p><b>METHODS</b>AECAs in sera of 39 CTD patients with PAH, 22 CTD patients without PAH, and 10 healthy donors as controls were detected with Western blotting. The prevalence of different AECAs in different groups was compared and its correlation with clinical manifestations was also investigated.</p><p><b>RESULTS</b>The prevalence of AECAs was 82.1% in CTD patients with PAH, 72.7% in CTD patients without PAH, and 20.0% in healthy donors. Anti-22 kD AECA was only detected in CTD patients with PAH (15.4%). Anti-75 kD AECA was more frequently detected in CTD patients with PAH than in those without PAH (51.3% vs. 22.7%, P < 0.05). In CTD patients with PAH, anti-75 kD AECA was more frequently detected in those with Raynaud's phenomenon or with positive anti-RNP antibody.</p><p><b>CONCLUSION</b>AECAs could be frequently detected in CTD patients with or without PAH, while anti-22 kD and anti-75 kD AECA might be specific in CTD patients with PAH.</p>

ABSTRACT

<p><b>BACKGROUND</b>Primary Sjögren's syndrome (pSS) is one of the autoimmune diseases with high incidence. There were several clinical investigations in Caucasian but seldom in Chinese. The aim of this study was to compare the difference of clinical manifestations, immunological features and prognosis of pSS between Caucasian and Chinese pSS patients.</p><p><b>METHODS</b>Five hundred and seventy-three patients who fulfilled the 2002 international classification (criteria) for pSS from Peking Union Medical College Hospital between 1985 and 2006 were screened retrospectively and compared with other populations.</p><p><b>RESULTS</b>(1) The study consisted of 524 (91%) female and 49 (9%) male patients (female: male = 10.7:1). Mean age at the onset of the disease was (39.0 ± 13.7) years and in 169 (29.5%) patients the disease onset occurred before the age of 30 years. The average duration from disease onset to pSS diagnosis was 48 months (range, 1 - 552 months). It had been shortened during the recent five years. (2) Dry mouth (84.5%) and dry eyes (70.0%) were the most common symptoms, significantly lower than foreign patients (P = 0.000). Two hundred and seventy-two (47.5%) patients presented with rampant caries, 160 (27.9%) with parotidomegaly. The positivity of xerostomia, xerophthalmia and salivary gland biopsy were 91.9%, 94.8% and 90.7%, respectively. (3) Systemic involvement occurred in 91.4% patients. Compared with studies done outside China, higher prevalence of fever 41.0%, myositis 4.9%, pericardial effusion 14.8%, pulmonary involvement 42.3%, renal involvement 33.5%, thyroid involvement 32.7%, pancrease involvement 5.6% (P < 0.01) and lower prevalence of fatigue, lymphadenectasis and Raynaud's phenomenon (P < 0.01) were seen. (4) Risk factors of death include pulmonary artery hypertension, liver damage and interstitial lung disease.</p><p><b>CONCLUSIONS</b>Chinese pSS differs significantly from the non-Chinese cases in terms of the age of onset, systemic involvement, autoantibodies and proportional mortality rate. Lung and liver damage were found to be the highest risk factors of the disease prognosis.</p>
