ABSTRACT

Objective:To identify the characteristics of nailfold capillaroscopy (NFC) of systemic sclerosis (SSc) and investigate whether more severe peripheral microangiopathy at NFC were related to the development of SSc.Methods:① The study included 115 patients (60 cases with SSc and 55 patients with other connective tissue diseases). All patients were treated with neither prednisone nor immunosuppressive drugs within 3 months before enrollment. We collected the following data: age, disease duration, disease onset, mRSS, high-resolution chest tomography (HRCT), echocardiography, pulmonary function, nailfold capillaroscopy and routine laboratory assessments. ② All the NFC definitions were used for semi-quantitatively scoring and Cutolo's qualitative assessment. ③ The relationship between NFC changes and joint, visceral involvement and autoantibodies in SSc patients was analyzed. ④ T test, Rank sum test and chi-square test were applied to analyze data. Results:① According to Cutoloqualitative assessment of NFC, patients of SSc with active/late pattern ( n=52) were very common than other CTD ( n=21) ( Z=-3.853, P<0.01). ② According to semiquantitative assessment, the scores of loss of capillaries [(1.67±0.60) vs (0.72±0.46), t=8.347, P<0.01)], irregular enlarged capillaries [(1.22±0.88) vs (0.74±0.50), t=3.178, P<0.01)], hemorrhage [(0.30±0.39) vs (0.10±0.21), t=3.090, P<0.01)], disorganization of the microvascular array [(0.38±0.38) vs (0.18±0.32), t=2.729, P<0.01)] were significantly higher than CTD. ③ The NFC of SSc patients was significantly different from CTD. The number of capillary loss ( Z=-4.194, P<0.01), input capillary dimensions ( t=3.704, P<0.01), output capillary dimensions ( t=3.913, P<0.01), wide diameter of capillary ( t=4.586, P<0.01), tortuous capillaries ( Z=-2.677, P<0.01), gaint capillary ( χ2=8.040, P=0.013), effusion ( Z=-2.278, P=0.023) were more increased than CTD. ④ The NFC pattern of SSc with lung involvement were mainly active and late (66%, 33/50), whereas early and active pattern (60%, 6/10) for those without respiratory system involvement ( Z=10.114, P=0.045) . The NFC pattern of SSc patients with joint involvement were mainly active and late (75%, 12/16), whereas early and active (66%, 29/44) for those without joint involvement ( Z=5.550, P=0.057) . Conclusion:The NFC of SSc patients is significantly different from CTD. NFC may be a suitable tool for disease evaluation.

ABSTRACT

Objective:To analyze the clinical features of patients with cardic involvement in eosinophilic granulomatosis with polyangiitis (EGPA), and to enhance the understanding.Methods:We retrospectively reviewed the clinical data of 16 patients with EGPA with cardiac involvement in Bethune hospital of Shan-xi from Jan 2012 to Jun 2019. T test, rank sum test and χ2 test were used for statistical analysis. Results:16 patients with cardiac involvement. There were 11 males and 9 female. The age of 16 patients with cardiac involvement ranged from 14 to 82 years old, and the average age of onset was (58±14) years. Compared with patients without cardiac invo-lvement was (41±15) years, the difference between the two groups was statistically significant ( t=3.230 , P<0.01). The analysis suggested that age was related to whether or not cardiac involvement. Cardiac related clinical symptoms occurred in 4 patients (25%). One patient presented with cardiac involvement as the initial symptom. The other 12 patients presented abnormal electrocardiogram (ECG), cardiac ultrasound or cardiac magnetic resonance imaging (MRI), including 10 patients (62%) with abnormal ECG, 13 patients (81%) with abnormal cardiac ultrasound examination, and1patient with cardiac MRI suggesting endocarditis. Among 16 patients with EGPA cardiac involvement, 14 presented with pulmonary involvement, 10 cases with nasal involvement, 9 cases with perip-heral neurological involvement, 9 cases with skin involvement, 6 cases with gastrointestinal involvement, 2 cases with kidney damage. Eosinophils (EO) were increased in all 16 patients, with a median value of 2.46 (1.49, 3.94) ×10 9/L, and EO was associated with cardiac involvement. Analysis of perinuclear anti-neutrophil cytoplasmic antibo-dies (pANCA) positive rate showed that only 2 of the 16 patients were positive. There was statistically significant difference ( P=0.017) compared with the group without cardiac involvement (8 patients were positive). All 16 patients were treated with glucocorticoid, 12 patients received immunosuppressive therapy, and 10 patients were treated with cyclophosphamide. During the ollow-up, 1 case died of heart failure, 1 case died of cerebral hemorrhage, 3 cases were lost to follow-up, and the other 11 cases were all stable after discharge. Conclusion:EGPA patients have a high incidence of cardiac involvement, and all cardiac stru-ctures can be involved, and most cardic involvement happens in ANCA negative patients. Cardiac involvement is one of the factors with poor prognosis.

ABSTRACT

Objective To evaluate the clinical efficacy of intra-articular injection of ozone in collagen-induced arthritis (CIA) rats and to assess its effects on serum receptor activator of nuclear factor κB ligand (RANKL) and osteoprotegerin (OPG) levels. Methods Forty weight age malched Wistar rats were randomly divided into normal control group (normal group), the CIA model group (CIA group), ozone (O 3 group), and methotrexate (MTX group). In addition to the normal control group, Freund's complete adjuvant and bovine type Ⅱ collagen were injected to establish the rat model of CIA. After the model was sucessfully developed, double ankle injection concentration ozone group of 40 μg/ml of O3 each 1 ml, 1 times a week, a total of injection for 3 weeks for the experimenal group. MTX group of 0.9 mg/kg was injected 1 times a week for 3 weeks for the MTX group. Degree of foot swelling was measured, and radiographic assessment of arthritis index (AI) score was performed. One week after treatment, angular vein blood was collected for the rats after the intervention, flow multi-factor detection technology was used to test each rat. T test or Wilcoxon rank test was used to compare the difference between groups. Results ① After 3 week administration with O3, dcgree of foot swelling, and AI of the O3 group was reduced significanly than the CIA group during the same period (foot swelling degree: O3 group: (4.21±0.14) ml, CIA group (9.12±0.17) ml, T=64.08, P=0.00; AI O3 group: [(2.97± 0.18) ml, CIA group: 5.76 ±0.13, T=37.24, P=0.00], and X-ray showed joint damage was alleviated. ② The serum level of RANKL in the CIA group was significantly higher than of the normal group [CIA model group 1890.70(797.03, 10571.94)], normal group [74.46(29.21, 95.37), T=43, P=0.005] during the same period; The serum level of RANKL in the O3 group was significantly lower than the CIA group [O3 group 28.09 (14.11, 207.30), CIA group 1890.70 (797.03, 10571.94), T=39, P0.05).③Serum RANKL/OPG of the CIA group was significantly higher than that of the normal group during this period, the difference was statistically significant [CIA group 250.68(42.33, 2959.78), normal group 4.32(3.16,5.30), T=36, P0.05). Conclusion Intra-articular injection of concentration of 40 μg/ml of O3 can reduce RA rat joint swelling degree, which may relate to the mechanism that O3 can lower levels of serum RANKL and RANKL/OPG ratio, reduce osteoclast formation and activation.

ABSTRACT

Objective Endothelial microparticles (EMPs) are direct indicator of endothelial cell activation or apoptosis,and may also reflect endothelial inflammation,increased coagulation,and vascular tone.The aim of this study is to investigate whether EMPs would be able to evaluate systemic involvement and be a new indicator of disease activity in Beh(c)et's disease (BD).Methods Thirty-nine consecutive BD patients (who fulfilled the modified International Study Group on BD in 1990 or International Criteria for BD in 2006) and 67 age and sex-matched healthy controls were enrolled (Including 37 patients with hypertension and 30 healthy subjects).The plasma levels of EMPs were measured by flow cytometry utilizing specific labels for endothelial MPs (CD31+ and CD42b-).The measurement data of each group were expressed as-x±s,and the comparison data betwen groups were analyzed by independent sample t test and analysis of variance,Spearman/Pearson correlation analysis,P<0.05 was statistically significant.Results The levels of circulating EMPs (CD31 + and CI42b-) were significantly elevated in the case group compared with the healthy control group and hypertension (F=6.845,P<0.05).Moreover,BD patients plasma EMPs were positively correlated with active BD (r=0.802,P<0.05).Vascular involvement in BD patients was higher than in patients without vascular EMPs,t=4.707,P<0.05.Gastrointestinal involvement in BD patients was more frequent than that in patients without Gastrointestinal involvement,t=2.673,P<0.05.Conclusion Levels of circulating EMPs are elevatedd in BD patients and correlated with disease activity in BD.Elevated EMPs may be a potential indicator to predict disease activity of BD.The plasma level of EMPs is increased,which indicats increased risk of vascular and digestive tract involvement in BD.

ABSTRACT

Objective To observe the expression of AdipoQ in Sj?gren's syndrome (SS) mice and its role in inflammation was investigated by recombinant gene transfection study in vivo. Methods As spon-taneous SS mice model, a total of 30 NOD mice were divided into 3 groups randomly: recombinant adenovirus (rADV-AdipoQ) group, normal saline control and simple adenoviruses (control group). The submandibular gland morphology, histopathological grading and the level of serum tumor necrosis factor-α (TNF-α), AdipoQ was compared between the three groups. The expression of AdipoQ on mice submandibular gland was assessed by means of semi-quantitative reverse transcriptase polymerase chain reaction. Results The submandibular glands of the mice of the control group were destructed, with focal lymphocytic infiltration and acinus atrophy. Compared with control model groups, the serum TNF-α and salivary gland AdipoQ expression was significantly down-regulated in the rADV-AdipoQ group [(248 ±30) vs (162 ±73) ng/ml] (P<0.05). Conclusion AdipoQ gene transfected SS mice can significantly improve the morphological features of tissues and decrease the concentration of TNF-αin serum, in addition, it can effectively inhibit inflammation, decrease the degree of protein and AdipoQgene expression. So the AdipoQ may be the protective gene in SS mice.

ABSTRACT

Objective To assess the diagnostic value of anti-mutated citrullinated vimentin antibodies (anti-MCV) for rheumatoid arthritis (RA), and compare it with anti-cyclic citrullinated peptide antibodies (anti-CCP), rheumatoid factors (RF). Methods Commercially available enzyme-linked immunosorbent assay (ELISA) kit was used to detect anti-MCV antibodies in a group of 177 RA patients, 46 patients with other rheumatic diseases, and 48 healthy blood donors. At the same time, anti-CCP, RF were detected. T test and χ2 test were selected. Results The average concentration of anti-MCV was (523±376) U/ml in RA, (96± 55) U/ml in patients with other rheumatic diseases, (34±18) U/ml in healthy controls. Different threshold levels (20, 40, 60, 80, 100, 120, 140 U/ml) for positive results were calculated bythe areas under the ROC curve (the areas were 0.521, 0.706, 0.769, 0.791, 0.816, 0.826, 0.822), then the best diagnosis efficacy for RA was determined as more than 120 U/ml. At this level, the sensitivity and the specificity for anti-MCV were 80.1% and 80.9% for RA diagnosis. The positive and negative predictive value were 92% and 67.8%. Comparing with anti-CCP, anti-MCV showed comparable specificity but higher sensitivity. And it's also better than RF apparently. If all 3 antibodies were detected at the same time, or anti-MCV combine with one of them, the sensitivity would increase to 95.7%. In addition, Anti-MCV showed positive in 32 of 67(55.2%) patients with RA whose anti-CCP was negative, meanwhile 31 of 59 (52.5%) patients with RA whose RF was negative. Conclusion RF and anti-CCP are complementary in diagnosing RA. The combination detection of RF and anti-CCP could significantly improve the specificity for the diagnosis of RA.

Objective To evaluate the efficacy and safety profile of methotrexate (MTX), leflunomide (LEF) and low-dose MTX and LEF (MTX + LEF) combined treatment for psoriatic arthritis (PsA). Methods This was a 24 weeks, two-center, open-labeled, controlled trial All subjects fulfilled the moll and wright criteria for definite PsA. Subjects were given one of the 3 regimens, MTX, or LEF, or MTX + LEF. The primary end point was proportion of psoriatic arthritis response criteria(PsARC)response. The secondary end point was proportion of modified 20% improvement of American College of Rheumatolngy (ACR20) response. Results At week 24, the percent of patients achieving PsARC in MTX, LEF and MTX + LEF group were 75.0% ,68. 8% ,83.3% respectively, and the percent of patients achieving ACR20 were 66. 7% ,50. 0% ,83. 3% respectively. At week 24, tender joint counts, swollen joint counts, patient's assessment of pain, patient's global assessment (PGA), physician' s global assessment, health assessment questionnaire(HAQ)were significantly improved compared with base-line values(P <0. 05). At week 24, the improvement of patient's assessment of pain, HAQ, ESR were better in the MTX + LEF group compared with LEF group while the improvement of patient's assessment of pain, PGA, HAQ, ESR were better in the MTX group compared with LEF group (P < 0. 05). The incidence of treatment related adverse events was 38.5%, 38. 9% and 35% in MTX, LEF and MTX + LEF group respectively. There was no serious adverse reactions. Conclusion Low dose MTX + LEF regimen showed similar good efficacy and safety profde for PsA patients.

ABSTRACT

Objective To evaluate the safety and tolerance of tumor necrosis factor-or (TNF-α)antagonists in the treatment of rheumatic diseases. Methods The incidence of adverse events and their ultimate outcomes based on the clinical symptoms, signs and laboratory parameters of patients treated with etanereept or infliximab during January 2007 to October 2008 were analyzed. Results Severty eight patients were included. Most were rheumatoid arthritis (35%) and ankylosing spondylitis (41%) patients. Few of them were psoriasis arthritis (17%) patients and undifferentiated spondyloarthropathy (6%) patients. Among those patients, 59 patients were treated with etanercept, 7 patients (12%) had adverse events in which the majority were injection reactions, upper respiratory tract infection and tuberculosis. Nineteen patients were treated with infliximab, in which 3 patients (16%) had adverse events. One patient (AS) had upper respiratory tract infection. One case (AS) had red papules all over the body and palpitations in the first 24 hours after two infusions. One patient (RA) had fever without identifiable causes after the 4th infusion. Some of the adverse reactions might subside without intervention, while others were controlled after proper treatment. Conclusion Both etanercept and infliximab have good safety and tolerance in treating rheumatic diseases, the adverse reactions are generally mild and can be controlled by appropriate treatment.
