Objective To explore the association between disease activity and health utility values(HUV)in patients with rheumatoid arthritis(RA)in China,and to analyze other factors that may affect health utility values,providing a basis for individualized treatment and health management for RA patients.Methods Based on the Chinese Registry of Rheumatoid arthritis cohort,this study included 1 017 diagnosed RA patients.The EQ-5D-3L scale was used to assess the health utility values,while clinical data,disease activity,and potential influencing fac-tors(such as age,gender,and comorbidities)were collected.Tobit regression models were employed to analyze the association between disease activity and health utility values,and to investigate other potential influencing factors.Results The median health utility value for RA patients was 0.78[0.59,0.89].Patients with moderate to high dis-ease activity had significantly lower health utility values as compared to those in remission phase or with low disease activity(median 0.70 vs.0.87,P＜0.001).Tobit regression analysis showed a significant association between disease activity and health utility values(P＜0.001).Additionally,older age,female gender,use of glucocorticoids,and co-morbidity with diabetes were associated with lower health utility values(P＜0.05).Conclusions Health utility values of RA patients are closely related to disease activity,with higher disease activity leading to a significant reduction in health utility values.Early control of RA disease activity may help improve patients' quality of life.

Objective To establish a multi-state Markov model of systemic lupus erythematosus(SLE)for patients in China and to explore the transition rule of organ damage accumulation and possible factors affecting the transition between states.Methods A retrospective cohort study was conducted using the data from CSTAR.The Systemic Lu-pus International Collaborating Clinics/American College of Rheumatology Damage Index(SDI)was divided into five irreversible disease states(SDI=0,1,2,≥3,and death,marked as S0,S1,S2,S3,Death).The R"mstate"package was used for statistical analysis.Results This study included 23 926 cases of SLE patients with cumulative follow-up of 12 030 visits.Among these patients,21 070 patients had no any organ damage at baseline.At the follow-up period,the transition probabilities of organ damage of S0→S1,S1→S2,S2→S3,S3→Death were 7.01％,12.58％,10.64％,and 12.19％,respectively.The multi-state Markov model showed that age,gender,disease dura-tion,SLEDAI score,corticosteroid dosage,and involvement of major organs were associated with the transition of or-gan damage status,each 1 year increased was associated with a 2％～3％increase in risk of damage accumulation risk(P＜0.01).Also,neurological(S0→S 1:HR=1.34;S1 →S2:HR=1.53;S2→S3:HR=1.73),cardiopulmonary(S0→S1:HR=3.66;S 1→S2:HR=1.51;S2→S3:HR=1.52),renal(S0→S 1:HR=1.24)and hematological involvement(S0→S1:HR=1.24)might be the risk factors.Conclusions The probability of organ damage accumulation in SLE pa-tients increases over time.Therefore,in the early stage of the disease,the involvement of important organs needs to be minimized and the treatment strategy should be dynamically adjusted at different stages of treatment.

Fibromyalgia syndrome （FMS） is a refractory， chronic non-articular rheumatic disease characterized by widespread pain throughout the body， for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies， and some non-drug therapies， such as acupuncture， Tai Chi， and Ba-Duan-Jin， have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine （TCM） by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine， the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine， including rheumatology， psychology， acupuncture and moxibustion， and encephalopathy， with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS， mitigation of common non-specific symptoms， preferential analgesic therapy， TCM pathogenesis and treatment advantages， and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis， poor patient participation， and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems， this paper suggests that rheumatologists should serve as the main diagnostic force of this disease， and they should improve patient participation in treatment decision-making， implement exercise therapy， and fully utilize the holistic and multidimensional features of TCM， which is effective in alleviating pain， improving mood， and decreasing adverse events. In addition， it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment， which is expected to improve the standard of diagnosis and treatment of FMS in China.

Connective tissue diseases(CTD)are a spectrum of heterogeneous diseases with multiple organ involvements.Interstitial lung diseases(ILD)are serious complications of CTD.There is great heterogeneity in pathogenesis,clinical manifestations,and treatment of different CTD-ILD.Previous basic and clinical studies have explored the pathogenesis of CTD-ILD,and the"dual-target"treatment strategy has therefore emerged.The implementation of the"dual-target"treatment strategy helps to control CTD activity and lung inflammation in the early stage,prevent the progression of pulmonary fibrosis,and thus improve patient survival and quality of life.

Sjögren's syndrome （SS）， a disorder of immune system， is one of the dominant diseases treated by traditional Chinese medicine （TCM）. China Association of Chinese Medicine organized experts in the field of TCM and western medicine rheumatology and pharmacology to discuss the advantages and optimal regimens of TCM for the treatment of SS. The experts generally agreed on the low early diagnosis rate of SS and the lack of targeted therapeutic drugs. In addition， autoimmune abnormality is the key factor in the occurrence of SS and deficiency of both Qi and Yin is the core pathogenesis. SS has unique tongue manifestations， which is expected to allow for the early diagnosis and treatment with integrated traditional Chinese and western medicine. TCM has advantages in treating SS in terms of alleviating clinical symptoms and systemic involvement， individualized treatment， relieving sleep and mood disorders， preventing the occurrence in the early stage， and enhancing the effectiveness and reducing toxicity in the treatment by integrated TCM and western medicine. In general， TCM has advantages in different stages of SS. Internal and external use of TCM， acupuncture， and acupotome are all available options. The optimal regimens should be determined on the basis of pattern identification， stage of disease， and the advantages of TCM. Clinical characteristics and biomarkers of SS should be studied to classify patients， so as to design precision evidence-based TCM regimens for SS. On the basis of unique tongue manifestations of SS， models for early diagnosis and poor prognosis identification of SS should also be established to achieve early prevention and treatment and to improve the prognosis. In the future， we should vigorously carry out high-quality evidence-based medical research on the treatment of SS by TCM and integrated traditional Chinese and western medicine and develop relevant guidelines to optimize and standardize current diagnosis and treatment， thereby laying a basis for clarifying and explaining the advantages of TCM in treating SS.

Objective:To investigate the clinical features of patients with coexisting connective tissue disease (CTD) and sarcoisosis and to avoid misdiagnosis and mistreatment.Methods:To analyze the clinical manifestations, laboratory data, imaging and pathological features of patients with CTD combined with sarcoidosis in Peking Union Medical College Hospital from January 1985 to December 2021.Results:There were 17 patients with CTD(including 10 SS, 2 DM, 2 PBC, 1 SLE, 1 RA and 1 UCTD), combined with sarcoidosis, with a mean age of (55±10) years old and the ratio of male-to-female was 1:16. Eight patients were diagnosed as CTD before sarcoidosis, while 3 patients after sarcoidosis. The other 6 patients were diagnosed with the two diseases almost simultaneously. Lymphadenopathy(12/17), pulmonary nodules (8/17), subcutaneous nodules (4/17), rash (4/17) and blurred vision (1/17) were the main manifestations of patients with the onset of nodular disease. Nine patients were treated based on the presentation of sardoisis and 5 patients for CTD; 3 patients were treated for both diseases at the same time. All 17 patients discharged with improvement after treatment.Conclusion:When sarcoidosis do coexists with CTD, occult CTD might occur. It is important to investigate specific manifestations including pathological features of sarcoidosis and differentiate it from CTD.

Objective:To investigate the clinical characteristics of patients with rheumatic diseases and abnormal liver function, as well as determine the proportion and severity of liver function abnormalities.Methods:Cross-sectional study. Data were collected from patients registered in the Chinese Rheumatism Date Center from 2011 to 2021. The rheumatic diseases analyzed in this study were rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjogren syndrome (SS), ankylosing spondylitis (AS), and gout. Patient data, including demographic characteristics [ such as age, sex, body mass index,(BMI), and smoking history], liver function test results [including alanine aminotransferase (ALT), aspartate aminotransferase, alkaline phosphatase(ALP), and total bilirubin], and use of anti-rheumatic immune drugs and liver-protective drugs, were collected and compared between groups with normal and abnormal liver functions. In addition, the proportions of abnormal liver function were compared between sex and age groups.Results:A total of 116 308 patients were included in this study, including 49 659 with RA, 17 597 with SLE, 9 039 with SS, 11 321 with AS, and 28 692 with gout. The lowest proportion of liver function abnormalities was observed in patients with RA[11.02% (5 470/49 659)], followed by those with SS[17.97% (1 624/9 039)] and AS [18.22% (2 063/11 321) ], whereas patients with SLE [21.14% (3 720/17 597) ] and gout [28.73% (8 242/28 692)] exhibited the highest proportion of these abnormalities. Elevated ALT, mostly classified as grade 1, was the most commonly noted liver function abnormality, whereas elevated ALP was the least common. Some patients who took liver-protective drugs had normal liver function, with the lowest percentage observed in patients with gout [7.45% (36/483) ] and ranging from 21.7% to 30.34% in patients with RA, SLE, SS, and AS. The proportion of liver function abnormalities was higher in males than in females for all disease types [RA: 13.8%(1 368/9 906) vs. 10.3%(4 102/39 753); SLE: 33.6% (479/1 424) vs. 20.0% (3 241/16 173); SS: 25.4%(111/437) vs. 17.6%(1 513/8 602); AS: 20.1%(1 629/8 119) vs. 13.6% (434/3 202); and gout: 29.3% (8 033/27 394) vs. 16.1% (209/1 298)]. In RA, SLE, and AS, the proportions of liver function abnormalities were similar across all age groups. In SS, the proportion of liver function abnormalities increased with age [<40 years: 14.9%(294/1 979); 40-59 years: 18.1%(858/4 741); ≥60 years: 20.4%(472/2 319)], whereas a reversal of this trend was observed in gout [<40 years: 34.9%(4 294/12 320); 40-59 years: 25.5%(2 905/11 398);≥60 years: 21.0%(1 042/4 971)].Conclusions:The proportions of combined liver function abnormalities in patients with rheumatologic diseases were high, and the utilization rates of liver-protective drugs were low. It is necessary to pay more attention to monitoring patients′ liver function, timely administer liver-protective drugs, and optimize liver-protective regimens during the treatment of rheumatic diseases.

BACKGROUND: The clinical features of enthesitis in patients with psoriatic arthritis (PsA) have been reported in some Western countries, but data in China are very limited. This study aimed to describe the characteristics of enthesitis in Chinese patients with PsA and compared them with those in other cohorts. METHODS: Patients with PsA enrolled in the Chinese Registry of Psoriatic Arthritis (CREPAR) (December 2018 to June 2021) were included. Data including demographics, clinical characteristics, disease activity measures, and treatment were collected at enrollment. Enthesitis was assessed by the Spondyloarthritis Research Consortium of Canada (SPARCC), Maastricht ankylosing spondylitis enthesitis score (MASES), and Leeds enthesitis index (LEI) indices. A multivariable logistic model was used to identify factors related to enthesitis. We also compared our results with those of other cohorts. RESULTS: In total, 1074 PsA patients were included, 308 (28.7%) of whom had enthesitis. The average number of enthesitis was 3.3 ± 2.8 (range: 1.0-18.0). More than half of the patients (165, 53.6%) had one or two tender entheseal sites. Patients with enthesitis had an earlier age of onset for both psoriasis and arthritis, reported a higher proportion of PsA duration over 5 years, and had a higher percentage of axial involvement and greater disease activity. Multivariable logistic regression showed that axial involvement (odds ratio [OR] 2.21, 95% confidence interval [CI], 1.59-3.08; P <0.001), psoriasis area and severity index (PASI) (OR: 1.03, 95% CI: 1.01-1.04; P = 0.002), and disease activity score 28-C reactive protein (DAS28-CRP) (OR: 1.25, 95% CI: 1.01-1.55; P = 0.037) were associated with enthesitis. Compared with the results of other studies, Chinese patients with enthesitis had a younger age, lower body mass index (BMI), a higher rate of positive human leukocyte antigen (HLA)-B27, more frequent dactylitis, and a higher proportion of conventional synthetic disease-modifying antirheumatic drugs' (csDMARDs) use. CONCLUSIONS Enthesitis is a common condition among Chinese patients with PsA. It is important to evaluate entheses in both peripheral and axial sites.
