Objective To investigate the clinical characteristics of patients with polymyositis(PM) and dermatomyositis (DM), and compare the differences of PM/DM to help the understanding of clinical diagnosis and treatment. Methods One hundred and forty-five hospitalized PM/DM patients from Department of Rheumatology of the First Affiliated Hospital of Xiˊan Jiaotong University were collected from May 2008 to December 2014, and the clinical manifestations, muscle enzymes, electromyogram, muscle biopsy, treatment outcome were retrospectively analyzed. Mann-Whitney U test and χ2 test were used for statistical analysis. Results The most common initial symptom of PM was muscle weakness, accounted for 51.2%, while rash was the initial presentation in most DM patients(43.1%). The incidence of interstitial lung disease (ILD) (62.7% vs 39.5%, χ2=11.009, P=0.001), and the elevation of CRP (48.9% vs 26.8%, χ2=10.272, P=0.001) were all higher in DM than PM, while the elevation of level of CK (85.4% vs 61.8%, U=-2.668, P=0.008) and CKMB (82.9%vs 41.2%, U=-3.303, P=0.001) were more common in PM compared with DM. The pathological study showed degeneration of muscle fiber, connective tissue hyperplasia in most PM patients, and perimysium atrophy, vacuoles degeneration, muscle bundles, perivascular inflammatory cell infiltration were observed in most DM patients. During the follow-up, the clinical remission rate was 57.5%, the relapse rate and the mortality rate was 7.5%and 31.1%respectively. The mortality rate was higher in DM than PM (34.6% vs 21.4%, χ2=4.861, P=0.027). Infection and tumors were the major causes of death, and the lung was the most common site of infection. Conclusion Differences in the clinical features, muscle enzymes, CRP level, pathology and the mortality rate between PM and DM are evident, while ILD, infection and the higher mortality rate are more common in DM than in PM.

OBJECTIVE: To investigate the diagnosis and treatment of mixed connective tissue disease (MCTD) and myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) associated vasculitis, which is a rare clinical entity in medical practice. METHODS: A 35-year-old female of Asian origin was admitted to our hospital due to complaints of Raynaud's phenomenon, myalgia, arthralgia and fatigue. The patient was diagnosed as MCTD in the out-patient department 8 months prior to admission based on Alarcon-Segovia classification criteria of Raynaud's phenomenon, myalgia, arthralgia and a high anti-U1 ribonucleoprotein antibody level. Interstitial lung disease was determined by chest computed tomography. Renal biopsy was performed because of marked proteinuria on 24 h urine collection. Histopathological examination revealed glomerulonephritis with fibrocellular/cellular crescents, in which moderate staining of IgM was shown by direct immunofluorescence. She was tested positive for myeloperoxidase antineutrophil cytoplasmic antibody. RESULTS: High dose of methylprednisolone (500 mg/d for 3 days) was started intravenously when the results of renal biopsy were obtained. Oral prednisone and intravenous cyclophosphamide therapy (0.8 g/month) were continued for 12 months. Daily urinary protein loss decreased dramatically and serum creatinine was maintained at a normal level. CONCLUSION Corticosteroids and cyclophosphamide are effective in the treatment of MPO-ANCA associated glomerulonephritis in MCTD.

Objective:To analyze the bone turnover markers in systemic lupus erythematosus (SLE) patients with different disease activity and the risk factors of osteoporosis.Methods:In this retrospective study, a total of 417 SLE inpatients were enrolled from the Department of Rheumatology and Immunology, the First Affiliated Hospital of Xi′an Jiaotong University, from March 2019 to June 2020. According to SLEDAI score, the patients were divided into 3 groups: 281 patients disease with inactive disease group; 99 patients with mild active disease group; and 37 patients with moderate/severe active disease. ANOVA test was used to compare the differences in serum bone turnover markers (PTH, NOST, VITDT, β-crossl, TP1NP, Ca and P) and bone density (Spine L 1~4 and left femur) among the three groups, and Tukey's method was used for the two groups comparison. Logistic regression analysis was used to investigate the risk factors of osteoporosis. Results:Serum VITDT, β-crossl and Ca levels were significantly different among the 3 groups ( F=11.66, P<0.001; F=7.22, P<0.001; F=29.38, P<0.001). Compared with patients in the inactive group, patients with both the mild disease group (VITDT: t=3.94, P<0.001; Ca: t=5.10, P<0.001) and the moderate/severe disease group (VITDT: t=3.33, P<0.001; Ca: t=7.19, P<0.001) had lower VITDT levels [(20.3±9.7) ng/ml vs. (15.9±9.3) ng/ml vs. (14.8±7.4) ng/ml] and serum Ca levels [(2.19±0.15)mmol/L vs. (2.09±0.21)mmol/L vs. (2.00±0.16)mmol/L]. Moreover, the moderate/severe disease group patients had much lower serum Ca levels ( t=2.36, P<0.05), compared with patients with the mild disease group. Compared with the patients with inactive group, both the mild activey group ( t=3.06, P<0.01) and the moderate/severe activie group ( t=2.99, P<0.01) patients had higher serum β-crossl levels [(419±316) pg/ml vs. (543±424) pg/ml vs. (586±343) pg/ml]. Compared with patients with the inactive disease group both patienes with the mild active group and the moderate/severe disease group patients had significantly decreased spine BMD ( t=2.75, P<0.01; t=2.71, P<0.01), Z-score ( t=5.65, P<0.001; t=4.70, P<0.001), T-score ( t=3.02, P<0.01; t=3.37, P<0.001), whereas, no difference was found between the mild disease group and moderate/severe disease group. Compared with the inactive group patients, both the mild active group and moderate/severe disease group patients had lower left femur BMD levels ( t=2.83, P<0.001; t=2.65, P<0.001) and T-score ( t=2.24, P<0.05; t=1.977, P<0.05) and no difference was found between the mild disease group and the moderate/severe disease group. Logistic regression analysis showed that age [ HR (95% CI)=1.080 (1.052, 1.109), P<0.001], BMI [ HR (95% CI)=0.801 (0.704, 0.911), P<0.001], SLEDAI score [ HR (95% CI)=1.047 (1.025, 1.076), P<0.05] and cumulative glucocorticoids dose [1.046 (1.006, 1.087), P<0.05] were associated with osteoporosis of SLE patients. Conclusion:Abnormal bone metabolism and decreased bone density are associated with SLE disease activity in SLE patients, especially in those with advanced age, low BMI and receiving high cumulative dose of glucocorticoids. Osteoporosis should be proactively prevented in the SLE patients.

Objective:To investigate the effect of systemic lupus erythematosus (SLE) on the status of hepatitis B virus (HBV) infection, and provide data for clarifying the relationship between autoimmunity and infection.Methods:SLE patients in the department of rheumatology and immunology of the First Affiliated Hospital of Xi'an Jiaotong University from January 2016 to December 2019 were screened. A retrospective case-control study was carried out. SLE patients with positive hepatitis B surface antigen (HBsAg) were gender and age matched with chronic hepatitis B (CHB) in a 1∶4 ratio. Chi-square test was used to compared the positive rates of hepatitis B e antigen (HBeAg) and Paired-Samples t test or Signed rank Wilcoxon test was used to compare the HBV DNA load and HBsAg titer. Results:The positive rate of HBsAg in SLE patients was lower than the prevalence rate of HBsAg in general population in the second Chinese National Hepatitis Seroepidemiological Survey in 2006 [2.2%(27/1 227) vs 7.2%], but the positive rate of HBcAb was not obviously different from that in general population in China [33.9%(416/1 227) vs 34.1%]. Compared with matched CHB patients, the positive rate of HBeAg [37.0%(10/27) vs 58.3%(63/108), χ2=3.94, P=0.047], the HBV DNA load [0(0, 3.7) lg U/ml vs 4.8(2.2, 3.7) lg U/ml, Z=-5.37, P<0.001] and HBsAg titer [(2.0±1.5) lg U/ml vs (3.3±1.1) lg U/ml, t=-4.26, P<0.001] in SLE patients were lower. Conclusion:The HBV infection status of SLE patients is different from that of patients with chronic hepatitis B and the HBV infection is more likely to be controlled.

【Objective】 To investigate the clinical characteristics and risk factors of systemic lupus erythematosus （SLE） combined with symptomatic knee osteonecrosis （KON）. 【Methods】 We retrospectively analyzed the clinical data of 26 cases of SLE with KON treated in the Department of Rheumatology and Immunology， The First Affiliated Hospital of Xi’an Jiaotong University， from April 2013 to December 2019. 【Results】 The age of the 26 patients （2 males and 24 females） was （35.3±9.0） years old at the diagnosis of KON， and the course of SLE was （48.7±35.1） months. The time from glucocorticoids initiation to the development of KON was （37.8±42.7） months， the maximum dosage of methylprednisolone was （197.7±290.7）mg and the cumulative dosage was （6.02±6.66）g. Six of the patients had a history of large-dose glucocorticoids impulse therapy. All of them had a history of immunosuppressant treatment. SLEDAI score was （11.23±5.46） at the onset of SLE and （4.46±4.81） at the onset of KON. The most common initial symptoms were edema and arthritis. The most common systemic damages were blood system damage and lupus nephritis. The most common immunological abnormalities were positive antinuclear antibody （25/26）， positive anti-SSA/Ro52kD antibody （16/26）， and positive anti-SmD1 antibody （15/26）. There were 4 patients with positive anticardiolipin antibody （ACA）. Bone metabolism was characterized by vitamin D3 （Vit-D3） deficiency， insufficient N-terminal osteocalcin （N-OST）， and increased β-C-terminal telopeptide of type I collagen （β-CTx）. In 9 out of the 26 patients， SLE was combined with aseptic necrosis of the femoral head. Multifocal bone necrosis （at least 3 lesions） was common （12/26）. Longer disease course and glucocorticoids using time， larger cumulative dose and ACA positive were seen in patients with multifocal bone necrosis compared with those who had one lesion site. 【Conclusion】 KON most possibly occurs 3 to 4 years after the diagnosis of SLE， which is associated with high disease activity， large hormone dose， and long duration in the treatment process. Multifocal bone necrosis is easily seen in patients with severe disease， large initial hormone dose and high cumulative dose， as well as in ACA positive patients.

【Objective】 To evaluate musculoskeletal ultrasound (MSUS) detected subclinical synovitis of rheumatoid arthritis (RA) with different clinical remission criteria so as to explore the clinical characteristics of subclinical synovitis. 【Methods】 Forty-six consecutive patients with RA in clinical remission [disease activity score-28 (DAS28)≤2.6] underwent clinical and MSUS examinations at baseline and 1 year follow-up. Clinical remission was defined according to the DAS28 using the erythrocyte sedimentation rate (DAS28-ESR) and C-reactive protein level (DAS28-CRP), clinical disease activity index (CDAI), simplified clinical disease activity index (SDAI), and American College of Rheumatology/European League Against Rheumatism criteria Boolean (ACR/EULAR criteria). Subclinical synovitis was assessed by MSUS. Differences between the subclinical synovitis and non-subclinical synovitis groups were analyzed. 【Results】 The percentages of patients who achieved DAS28-ESR, DAS28-CRP, CDAI, SDAI, and ACR/EULAR remission at baseline and 1 year were 97.8%, 95.6%, 67.4%, 54.3%, 52.2% and 91.3%, 93.5%, 54.3%, 50.0%, and 45.6%, respectively. Subclinical synovitis was detected in 55.5%, 54.5%, 45.2%, 40.0%, 41.6% and 45.2%, 46.5%, 40.0%, 39.1%, and 38.1% of these patients, respectively. There were 45.6% and 41.3% patients who fulfilled all the criteria, yet 38.1% and 36.8% still had evidence of subclinical synovitis at baseline and 1 year. Compared with the patients without subclinical synovitis, those with subclinical synovitis had a significantly positive rate of anti-CCP antibody and a higher disease activity score at baseline (P<0.05). 【Conclusion】 MSUS detected subclinical synovitis is common. The positive anti-CCP antibody and higher disease activity score at baseline may be related to subclinical synovitis in patients with RA in clinical remission.
