ABSTRACT
Objective:To investigate the prevalence of hypertension and its associated factors in rheumatoid arthritis (RA) patients.Methods:Consecutive Chinese patients with RA were recruited from August 2015 to September 2019 at Department of Rheumatology, Sun Yat-sen Memorial Hospital. Demo-graphic data and clinical data were collected including indicators of disease activity, functional assessment and radiographic assessment, comorbidities and previous medications. Logistic regression analysis was used to evaluate the related factors of hypertension in RA patients.Results:There were 674 RA patients recruited with 82.3%(555/674) female and mean age (50±13) years. The prevalence rate of hypertension was 32.9% (222/674), followed by dyslipidemia (9.9%, n=67), type 2 diabetes (8.8%, n=59), hyperuricemia (8.5%, n=43), fatty liver disease (8.0%, n=54), cardiovascular disease (6.2%, n=42) and chronic kidney disease (3.3%, n=22). Compared with those without hypertension, RA patients with hypertension had advanced age with longstanding disease duration, higher disease activity indicators, worse joint destruction, and higher proportions of comorbidities. Multivariate logistic regression analysis showed that comorbidities including hyperuricemia [ OR=1.977, 95% CI(1.002, 3.900)], dyslipidemia [ OR=1.903, 95% CI(1.102, 3.288)] and fatty liver disease [ OR=2.335, 95% CI(1.278, 4.265)] were risk factors of hypertension after adjustment for age and gender. Conclusion:Hyperten-sion is the most common comorbidity in RA patients which is associated with comor-bidities including hyperuricemia, dyslipidemia and fatty liver disease. Detection and management of hyperten-sion and other cardiovascular disease related comorbidities in RA patients should be emphasized.
ABSTRACT
Objective:To analyze the clinical characteristics of patients with eosinophilic granulo-matosis with polyangiitis (EGPA) and improve the understanding of the disease.Methods:EGPA patients who fulfilled the 1990 American College of Rheumatology (ACR) classification criteria were recruited from Sun Yat-sen Memorial Hospital Sun Yat-sen University between December 2003 and April 2020. Their demographic characteristics, clinical manifestations, laboratory and auxiliary examinations were analyzed retrospectively. Mann-whitney U test and χ2 test were used for statistical analysis. Results:Among 52 EGPA patients, 34 (65.4%) were males and the median age at disease onset was 47(38-55) years. The median time from disease onset to diagnosis was 30(4-96) months. The most common initial symptoms were respiratory (61.5%) and nose/paranasal sinus (21.2%) involvement. The most common department for the first visit was respiratory medicine (53.8%), followed by rheumatology (11.5%). 44.2% EGPA patients were diagnosed by rheumatologists. The most common clinical manifestations were asthma (88.5%), nose/paranasal sinusitis (84.6%), pulmonary (76.9%) and nervous system (61.5%) in volvement. Eight(15.4%) patients were positive for antineutrophil cytoplasmic antibodies (ANCA). Patients with positive ANCA had lower incidence of asthma, but higher incidence of general symptoms especially arthralgia and renal involvement, elevated eosinophil count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Birmingham vasculitis activity score and vasculitis damage index than patients with negative ANCA (all P<0.05). 21.2%-34.6% EGPA patients had poor prognostic factors. Conclusion:Early diagnosis of EGPA is important. EGPA patients with positive ANCA may be more severe than patients with negative ANCA. The management should be a multi-disciplinary collaboration between rheumatologists and pulmonologists.
ABSTRACT
Objective To explore the outcomes of free flap from the radial artery superficial palmar branch (RASP) innervated by the lateral cutaneous nerve of the forearm for repairing the defects of finger pulp. Methods From April, 2013 to February, 2015, 20 fingers in 20 cases were treated with free flap from RASP innervated by the lateral cutaneous nerve of the forearm. The area of flap was from 1.8 cm×2.0 cm to 2.0 cm×4.0 cm. Postoperative fol-low up was done termly. Results All 20 flaps survived. All cases were followed-up for 7-20 months ( averag, 12 months). The flaps appeared well with good texture. The two-point discrimination was from 7 mm to 12 mm, and grad-ed with S3 and S3+sensation. There was little scar noted at the donor site in the wrist. There was no influence of hand and wrist function. Conclusion The method of using free flap from SASP innervated by the lateral cutaneous nerve of the forearm to repair the defects of finger pulp has good clinical effect.
ABSTRACT
Objective To observe the efficacy and safety of tocilizumab on patients with refractory rheumatoid arthritis (RA).Methods Eighteen RA patients who were refractory to disease-modifying antirheumatic drugs (DMARDs) or tumor necrosis factor-α (TNF-α) antagonist were treated with tocilizumab were included into this study.Their clinical disease activity indices,Hospital Anxiety and Depression Scale (HADS)and safety were evaluated regularly.Statistical analysis was conducted with Mann-Whitney U test and x2 test.Results According to clinical disease activity index,44％(8/18) of patients reached treatment target 2 weeks after the first infusion of tocilizumab,and 78％ (14/18) reached treatment target after three infusions of tocilizumab.Fifty-six percent (10/18) of patients had anxiety and 22％ (4/18) had depressive symptoms at baseline.After three infusions of tocilizumab,6％(1/18) had anxiety symptoms and 11％(2/18) had depressive symptoms.The adverse effects included upper respiratory tract infection,aminotransferase elevation and neutropenia (3 patients,respectively).Conclusion Tocilizumab can rapidly and significantly improve the disease activity and psychological state with good tolerance and safety,which can be applied to Chinese refractory RA patients who failed with DMARDs or TNF-α antagonist.
ABSTRACT
Objective To investigate doctor's screening practice for hepatitis B virus (HBV) infection before immunosuppressive therapy for rheumatoid arthritis (RA) patients and clinical management of RA patients with positive surface antigen of HBV (HBsAg).Methods One hundred fifty doctors who treated RA patients in daily clinic were survied with a modified American College of Rheumatology (ACR) questionnaire which was composed of demographic data and 10 multiple-choice questions.Step-forward logistic regression analysis was performed to find out the influencing factors,then receiver operator characteristic curve analysis and area under the curve were performed to confirm the influencing factors.Results One hundred and thirtytwo effective questionnaires were collected.Before immunosuppressive therapy,HBV screening rate in outpatients with RA was significandy lower than that in hospitalized patients (68.7％ vs 94.6％,x2=31.5,P＜0.01).Only 23.7％(31/131) of doctors considered antiviral treatment for all RA patients with positive HBsAg.One hundred and thirteen doctors had clinical experience of antiviral treatment,but only 30.1％(34/113) and 23.9％ (27/113) of these doctors chose entecavir or adefovir as the antiviral drug respectively,59.3％ (67/113) prescribed antiviral drug before or together with immunosuppressive therapy compared with 40.7％(46/113) after HBV reactivation.Only 20.4％(23/113) of doctors would sustain antiviral treatment until the termination of steroid or disease modifying antirheumatic drugs (DMARDs).During immunosuppressive therapy for HBsAg(+) RA patients,11.4％(15/132) and 30.3％(40/132) of doctors reported no regular monitoring of aminotransferase or HBV DNA respectively.Conclusion Our survey shows that HBV screening rate in outpatients with RA is low and low awareness of antiviral treatment for all RA patients with positive HBsAg,and lack of awareness of indication,choosing of antiviral drugs,initiation,monitoring and duration of antiviral treatment during immunosuppressive therapy.Further medical education on the associated information and importance to collaborate with hepatologists should be emphasized.
ABSTRACT
ObjectivesTo examine the validity of high-frequency Doppler ultrasound in identifying knees synovitis in patients with rheumatoid arthritis(RA).MethodsNinety-five consecutive patients with active RA were examined withhigh-frequency Doppler ultrasound to examine synovitis signals in knees.Synovial tissue samples of 51 patients were obtained by closed needle biopsy from knees after ultrasound examination.Serial synovial tissue sections were stained with H&E and immunohistochemical staining,and the histopathological synovitis scores were evaluated.The relationship among clinical, histopathological and ultrasound synovitis indexes was analyzed by Spearman's rank order correlation test and receiver operating characteristic curve analysis.ResultsAmong 95 RA patients,the median thickness of synovial membrane in ultrasound was 2.8 mm,the median depth of effusion was 2.7 mm; Doppler signals of synovial blood flow were detected in 82％(78/95 ) of patients and the median semiquantitive grading of synovial blood flow was 1.0.The thickness of synovial membrane and synovial blood flow at Doppler ultrasound correlated positively with histological synovitis score,hyperplasia of the lining layer,and inflammatory infiltration in sublining area (the thickness of synovial membrane:r=0.438,0.424,0.368,respectively; synovial blood flow:r=0.357,0.377,0.347,respectively; all P＜0.05).Although there was no significant difference in clinical synovitis indexes between patients with histologically low-grade and high-grade synovitis,the thickness of synovial membrane and synovial blood flow in ultrasound in patients with histologically high-grade synovitis was significantly higher than those with low-grade synovitis(P=0.001,0.036,respectively).When the thickness of synovial membrane in ultrasound was ≥ 3.9 mm,the specificity of diagnosing the high-grade synovitis was 96.7％ and the sensitivity was 61.9％.ConclusionSynovitis signals at high-frequency Doppler ultrasound correlate with histopathological synovitis,and it might be helpful in evaluating the severity of histopathological synovitis.
