ABSTRACT

<b>Objective</b> To evaluate the effect of irregular follow-up during normalized prevention and control of novel coronavirus pneumonia (COVID-19) epidemic on BK virus (BKV) reactivation and clinical prognosis of kidney transplant recipients. <b>Methods</b> Clinical data of 363 kidney transplant recipients were retrospectively analyzed, and they were divided into the pre-epidemic follow-up group and during-epidemic follow-up group according to the follow-up time. All patients were followed up for 1 year. The follow-up interval was compared between two groups. The infection of BKV and the correlation between the infection process of BKV and renal graft function were analyzed in two groups. <b>Results</b> A total of 1 790 preson-times were followed up before COVID-19 epidemic and 2 680 during COVID-19 epidemic. Compared with the during-epidemic follow-up group, the follow-up intervals within 3, 3-6 and 7-12 months after kidney transplantation were shorter in the pre-epidemic follow-up group, and the differences were statistically significant (all <i>P</i><0.05). Within 1 year after kidney transplantation, 35 cases(32%) were diagnosed with BKV viruria, 3 cases(3%) of BKV viremia and 1 case(1%) of BKV-associated nephropathy (BKVAN) in the pre-epidemic follow-up group, and 53(25%), 3(1%) and 1(1%) in the during-epidemic follow-up group, with no statistical significance (all <i>P</i>>0.05). In the pre-epidemic follow-up group, the time for the initial diagnosis of BKV viruria was longer and the viral load of the first urinary BKV reactivation was smaller than those in the during-epidemic follow-up group, with statistical significance (both <i>P</i><0.05). The load of the first urinary BKV reactivation was positively correlated with the peak load of urinary BKV, and the differences between the baseline and serum creatinine levels at 1 and 3 months after BKV reactivation (all <i>P</i><0.05). <b>Conclusions</b> Irregular follow-up after kidney transplantation may lead to early BKV reactivation and higher detection value of the first viral load of urinary BKV, delay diagnosis and interventions, and lead to poor prognosis. It is urgent to establish a remote follow-up system to meet the follow-up requirements of kidney transplant recipients when public health incidents occur.

ABSTRACT

Objective To investigate the feasibility and clinical experience of kidney transplantation from donors with Marfan syndrome (MFS). Methods Clinical data of 2 recipients undergoing kidney transplantation from the same MFS patient were retrospectively analyzed and literature review of 2 cases was conducted. Characteristics and clinical diagnosis and treatment of kidney transplantation from MFS patients were summarized. Results The Remuzzi scores of the left and right donor kidneys of the MFS patient during time-zero biopsy were 1 and 2. No significant difference was observed in the renal arteriole wall compared with other donors of brain death and cardiac death. Two recipients who received kidney transplantation from the MFS patient suffered from postoperative delayed graft function. After short-term hemodialysis, the graft function of the recipients received the left and right kidney began to gradually recover at postoperative 10 d and 20 d. After discharge, serum creatinine level of the recipient received the left kidney was ranged from 80 to 90 μmol/L, whereas that of the recipient received the right kidney kept declining, and the lowest serum creatinine level was 232 μmol/L before the submission date (at postoperative 43 d). Through literature review, two cases successfully undergoing kidney transplantation from the same MFS donor were reported. Both two recipients experienced delayed graft function, and then renal function was restored to normal. Until the publication date, 1 recipient has survived for 6 years, and the other recipient died of de novo cerebrovascular disease at postoperative 2 years. Conclusions MFS patients may serve as an acceptable source of kidney donors. However, the willingness and general conditions of the recipients should be carefully evaluated before kidney transplantation. Intraoperatively, potential risk of tear of renal arterial media should be properly treated. Extensive attention should be paid to the incidence of postoperative complications.

ABSTRACT

Surgical technique of lung transplantation exerts significant impact on clinical prognosis of the recipients. Choosing an appropriate surgical incision determines the exposure of intraoperative visual field, which is the first step of surgical success and directly affects subsequent surgical procedures. Lung transplantation incision is usually considered as primary closure. Nevertheless, for patients with high-risk factors such as oversized lung allografts and primary graft failure after lung transplantation, primary closure cannot be achieved. Hence, delayed chest closure is an effective strategy. The selection of incisions and the adoption of delayed chest closure of lung transplantation exert profound impact upon perioperative prognosis, long-term quality of life and surgical complications of the recipients. Therefore, the development and research status of Clamshell incision, anterolateral incision, posterolateral incision and median sternal incision in lung transplantation were reviewed, highlighting the effect of incision patterns on clinical prognosis of lung transplantation and providing reference for the selection of incisions in clinical lung transplantation.

ABSTRACT

Three carboline fluorescent probes F1-F3 were designed and synthesized, based on lead compound JYJ-19, an antifungal compound discovered previously by our group. The antifungal activity in vitro results showed that compound F1 had moderate antifungal activity (MIC80 = 32 μg·mL-1). The stokes shift of F1 is 70 nm. The fluorescent probe F1 has good optical properties and can be used for fluorescence imaging research. Subcellular localization experiments results showed that F1 was enriched in the mitochondria of fungal cells. The detection of intracellular reactive oxygen species levels shows that JYJ-19 enhances intracellular reactive oxygen species levels. The above results indicated that carboline compounds could exert antifungal effects by acting on fungal mitochondria.

ABSTRACT

Objective To investigate the impact of SARS-CoV-2 infection on male semen quality through meta-analysis and retrospec-tive study.Methods Literature retrieval was conducted in PubMed,CNKI,Wanfang Database and CBM database.Meta-analysis was performed using Stata 15.0.The male patients meeting the inclusion criteria from our hospital were enrolled as study subjects.General demographic data and semen parameters were collected.Single factor analysis of variance and graphing of semen parameters were con-ducted using GraphPad Prism 9.5.1.The test level was set at 0.05.Results A total of 9 studies involving 267 patients were included in the meta-analysis.There were no significant differences in sperm concentration and survival rate before and after SARS-CoV-2 infec-tion(P>0.05).Semen volume and percentage of normal morphology significantly increased during 1-3 months after infection(P=0.005,P=0.010),with semen volume recovering to pre-infection level>3 months later(P>0.05).Sperm motility and progressive mo-tility increased>3 months after infection(P=0.046,P=0.045),recovering to pre-infection levels(P=0.099,P=0.098).Sperm DNA fragmentation index may be temporarily elevated within 3 months after infection but gradually decreased>3 months later.In the retrospective study of 8 cases,there were no statistical differences in semen parameters at different stages compared with pre-infection(P>0.05),but semen parameters showed a negative trend during<1 month after infection and recovered to pre-infection levels>3 months later.Conclusion The results of this laboratory study are basically consistent with the meta-analysis.SARS-CoV-2 infection in males only caused short-term negative effects on sperm morphology,vitality and DNA integrity,but generally recovered to pre-infection levels>3 months after infection.Due to the limitations of study subjects and sample size,the impact of SARS-CoV-2 infection on male semen quality needs to be further confirmed by long-term large-scale prospective studies.

ABSTRACT

BACKGROUND:There is no consensus on the optimal bone tunnel position in the lateral clavicle,which guides coracoclavicular ligament reconstruction.Postoperative complications such as enlargement of the lateral clavicle bone tunnel,bone osteolysis,clavicle fracture,and failure of internal fixation are likely to occur.Bone mass density plays an important role in the strength and stability of endophytic fixation.Regional differences in the bone mass density of the distal clavicle should not be overlooked in the repair and reconstruction of acromioclavicular dislocation.Currently,there are no quantitative clinical studies in humans regarding the bone mass density of the distal clavicle. OBJECTIVE:To measure the magnitude of bone mass density in different regions of the distal clavicle by quantitative CT to provide a reference for surgeons to repair and reconstruct the coracoclavicular ligament. METHODS:101 patients undergoing quantitative CT checking in Fuyang People's Hospital Affiliated to Anhui Medical University from October to December 2022 were enrolled,from which 1 616 samples of subdivisional bone mass density of the distal clavicle were measured.For each of the quantitative CT samples,firstly,the distal clavicle was divided medially to laterally into the following four regions:conical nodal region(region A),inter-nodal region(region B),oblique crest region(region C)and distal clavicular region(region D).Secondly,each region was divided into the first half and the second half to determine eight subdivisions,then setting semiautomatic region of interest(ROI)in each subdivision:(ROI A1,A2,B1,B2,C1,C2,D1,and D2).Thirdly,each quantitative CT scan was transferred to the quantitative CT pro analysis workstation,and cancellous bone mass density was measured in the distal clavicle ROI.Finally,the clavicular cortex was avoided when measuring. RESULTS AND CONCLUSION:(1)There was no statistically significant difference in bone mineral density on the different sides of the shoulder(P>0.05).(2)The analysis of bone mineral density in eight sub-areas of the distal clavicle A1,A2,B1,B2,C1,C2,D1,and D2 showed statistically significant differences(P<0.05).It could be considered that there were differences in bone mineral density in different areas of the distal clavicle.After pairwise comparison,there was no statistically significant difference in bone mineral density between A1 and A2,D1 and D2,A2 and B1(P>0.05),and there was a statistically significant difference in bone mineral density between the other sub-areas(P<0.05).(3)The bone mineral density in the region A2 of the anatomical insertion of the conical ligament was significantly higher than that in the inter-nodular area(region B)(P<0.05).The bone mineral density in the region A1 was higher than that in the region A2,but the difference was not statistically significant(P>0.05).The bone mineral density in the region C1 of the anatomical insertion of the trapezium ligament was higher than that in regions C2,D1 and D2,and the bone mineral density in the inter-nodular area(region B)was significantly higher than that in regions C and D(P<0.05).(4)These results have suggested that there are differences in bone mass density in different regions of the distal clavicle;regional differences in bone mass density in the distal clavicle during repair and reconstruction of acromioclavicular dislocation cannot be ignored.Consideration should be given not only to biomechanical factors but also to the placement of implants or bone tunnels in regions of higher bone mass density,which could improve the strength and stability of implant fixation and reduce the risk of complications such as bone tunnel enlargement,osteolysis,fracture and implant failure.

ABSTRACT

Objective:To investigate the efficacy of arthroscopic superior capsular reconstruction using composite autologous patch graft combined with tenodesis of the long head of the biceps tendon in the treatment of irreparable massive rotator cuff tears (IMRCT).Methods:A retrospective case series study was performed on 11 IMRCT patients who were admitted to Affiliated Fuyang Hospital of Bengbu Medical University (Fuyang People′s Hospital) from May 2020 to June 2022, including 7 males and 4 females, aged 54-74 years [(62.6±7.3)years]. All the patients were treated with arthroscopic superior capsular reconstruction using composite patch graft combined with tenodesis of the long head of the biceps tendon. The Visual Analogue Scale (VAS), Acromiohumeral Distance (AHD), Constant-Murley score and University of California Los Angeles (UCLA) score and active range of motion of the shoulder joint before, at 6 months after surgery and at the last follow-up were compared. At the last follow-up, the integrity of reconstructed superior capsule and the long head of the biceps tendon was evaluated using MRI of the shoulder joint. Postoperative complications were observed.Results:All the patients were followed up for 13-39 months [16(13, 36)months]. The VAS score, AHD, Constant-Murley score, and UCLA score were 2(2, 3)points, (9.1±1.1)mm, (56.1±5.4)points, and (19.7±2.8)points respectively at 6 months after surgery, which were all significantly improved from those before surgery [6(5, 7)points, (5.1±1.2)mm, (37.9±2.2)points, and (11.8±1.2)points] ( P<0.05). The VAS score, AHD, Constant-Murley score, and UCLA score were 0(0, 1)points, (8.4±0.9)mm, (83.6±3.8)points, and (28.2±2.3)points respectively at the last follow-up, which were all significantly improved from those before surgery ( P<0.05). At the last follow-up, the VAS score or AHD were not significantly improved from those at 6 months after surgery ( P>0.05); Constant-Murley score and UCLA score were both significantly improved from those at 6 months after surgery ( P<0.05). At 6 months after surgery, shoulder active ranges of motion in forward flexion, abduction and external rotation were (134.6±13.5)°, (124.6±18.6)° and 45(40, 50)° respectively, which were all significantly improved compared with those before surgery [(63.2±36.1)°, (65.0±23.1)°, and [30(20, 40)°] ( P<0.05). At the last follow-up, shoulder active ranges of motion in forward flexion, abduction and external rotation were (144.1±12.6)°, (139.6±15.4)° and 60(45, 65)° respectively, which were all significantly improved compared with those before surgery ( P<0.05). There were no significant differences in active range of motion of the shoulder in forward flexion, abduction and external rotation between 6 months after surgery and the last follow-up ( P>0.05). At the last follow-up, MRI revealed integrity of the reconstructed superior joint capsule and the long head of the biceps tendon in 10 patients. One patient developed resorption of the greater tuberosity and 1 showed a partial tear of the supraspinatus tendon at 1 year after surgery. Conclusion:Arthroscopic superior capsular reconstruction using composite autologous patch graft combined with tenodesis of the long head of the biceps tendon can relieve shoulder pain, decrease upward displacement of the humerus head, improve the function and range of motion of the shoulder joint, and reduce complications in the treatment of IMRCT.

ABSTRACT

This study aimed to explore the value of magnetic resonance imaging (MRI) T 2 mapping in the assessment of dermatomyositis (DM) and polymyositis (PM). Thirty-three confirmed cases (myosin group) and eight healthy volunteers (healthy control group) at the Department of Rheumatology and Immunology, the First Affiliated Hospital of Kunming Medical University, from October 2016 to December 2017, were collected and analyzed. Multiple parameters of the myosin group were quantified, including creatine kinase (CK), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), complement C3, and complement C4. Disease status was evaluated using a panel of tools: myositis disease activity assessment tool-muscle (MDAAT-muscle), myositis disease activity assessment tool-whole (MDAAT-all), health assessment questionnaire (HAQ), medical outcomes study health survey short form-36 item (SF-36), hand muscle strength test (MMT-8) score, and MRI T 2 mapping of muscle (22 muscles in the pelvis and thighs) T 2 values. The results showed that in the myositis group, the measurements for CK, ESR, CRP, complement C3, and complement C4 were 457.2 (165.6, 1 229.2) IU/L, 20 (10, 42) mm/1h, 3.25 (2.38, 10.07) mg/L, 0.90 (0.83, 1.06) g/L, and 0.18 (0.14, 0.23) g/L, respectively. The scores for MMT-8, MDAAT-muscle, MDAAT-all, HAQ, and SF-36 were 57.12±16.23, 5.34 (4.00, 6.00), 34.63±12.62, 1.55 (0.66, 2.59), and 44.66±7.98, respectively. T 2 values were significantly higher in all 22 muscles of the pelvis and thighs of patients with DM or PM compared with the healthy controls [(54.99±11.60)ms vs. (36.62±1.66)ms, P<0.001], with the most severe lesions in the satrorius, iliopsoas, piriformis, gluteus minimus, and gluteus medius muscles. The total muscle T 2 value in the myositis group was positively correlated with CK, MDAAT-muscle, MDAAT-all, and HAQ ( r=0.461, 0.506, 0.347, and 0.510, respectively, all P<0.05). There was a negative correlation between complement C4, SF-36, and MMT-8 scores ( r=-0.424, -0.549, and -0.686, respectively, all P<0.05). Collectively, the findings from this study suggest that MRI T 2 mapping can objectively reflect the disease status of DM and PM.

ABSTRACT

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.

ABSTRACT

ObjectiveTo investigate the characteristics of health-related physical fitness of patients with chronic neck pain, and the relationship between neck pain and physical fitness. MethodsFrom Match to June, 2020, 30 healthy controls and 30 patients with chronic neck pain in Dalian University of Technology were included. They were assessed with Neck Disability Index (NDI) and Visual Analog Scale for pain (VAS). The body composition, grip strength (dominant), shoulder joint flexibility, cardiopulmonary endurance and neck muscle endurance of all the participants were measured. ResultsThe content of standardized subcutaneous fat was more, and the trunk muscle content was less in the patients than in the healthy controls, while the standardized grip strength, endurance of neck flexor and extensor, right shoulder flexibility, absolute maximum oxygen uptake were all poorer (|t| > 2.088, P < 0.05). The score of VAS correlated (P < 0.05) with the score of NDI score (r = 0.407), grip strength (r = -0.406), endurance of neck extensor (r = -0.384), right shoulder joint flexibility (r = -0.551) and absolute value of maximal oxygen uptake (r = -0.510). ConclusionHealth-related physical fitness has been impaired for patients with chronic neck pain, and correlates with the intensity of pain.

ABSTRACT

ObjectiveTo investigate the therapeutic effect of rhubarb decoction (RD) retention enema on a rat model of minimal hepatic encephalopathy (MHE) and its mechanism of action based on bile acid (BA) metabolomics. MethodsA total of 55 male Sprague-Dawley rats were randomly divided into blank group (NC group with 10 rats), hepatic encephalopathy group (HE group with 15 rats), MHE group with 15 rats, and MHE+rhubarb decoction treatment group (MHEY group with 15 rats). Intraperitoneal injection of carbon tetrachloride (CCl4) and thioacetamide (TAA) was performed to establish a rat model of MHE or HE, and the rats were sacrificed after 2 weeks of administration. The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin (TBil), and total bile acid (TBA) and the concentration of blood ammonia were measured; the colonic contents were collected to measure pH value; liver and brain tissue samples were collected, and HE staining was used to observe the histopathological changes of the liver; the bile was collected, and liquid chromatography-mass spectrometry was used to perform BA-targeted metabolomics analysis. Continuous data were expressed as mean±standard deviation; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the NC group, the HE group and the MHE group had a significant increase in searching platform latency (after modelling and after administration) and a significant reduction in the number of platform crossings (all P<0.05); compared with the MHE group, the MHEY group had a significant reduction in searching platform latency (after administration) and a significant increase in the number of platform crossings, and the HE group had a significant increase in searching platform latency and a significant reduction in the number of platform crossings (all P<0.05). Compared with the NC group, the HE group and the MHE group had significant increases in AST, ALT, ALP, TBil, TBA, blood ammonia, and colon pH value (all P<0.05); compared with the MHE group, the MHEY group had significant reductions in AST, ALT, ALP, TBil, TBA, blood ammonia, and colon pH value (all P<0.05), and the HE group had significant increases in AST, ALT, ALP, TBil, TBA, blood ammonia, and colon pH value (all P<0.05).

ABSTRACT

Parkinson's disease (PD) is a kind of senile neurodegenerative disease. Dopaminergic drugs and anticholinergic drugs are the two major therapeutic drugs for PD. In the past several decades, great progress has been achieved on dopamines (DAs) and their synergists including monoamine oxidase B (MAO-B) inhibitors, catechol oxygen methyl transferase inhibitors, ergot and nonergot DA receptor agonists, DA precursor drugs, cannabis and isatin. Isatin is the inhibitor of endogenous specific anti-aging enzyme MAO-B, which has a variety of pharmacological activities. Moreover, the pharmacological mechanism of isatin may be associated with the regulatory functions of various protein activities.

ABSTRACT

Objective To preliminarily compare 6LiF-7LiF and CR39 in individual neutron dose monitoring, and to provide a reference for improving individual neutron dose monitoring. Methods According to the GBZ 128-2019, 26 radiation workers from 7 institutions received individual neutron dose monitoring with 6LiF-7LiF and CR39 at the same time. The monitoring results were analyzed. Results For most of the workers, the personal neutron dose equivalent Hp(10) was less than the minimum detectable level. The results with the two monitoring methods differed in 6 of 26 workers. Conclusion Both 6LiF-7LiF and CR39 monitoring methods can be used for individual neutron dose monitoring for radiation workers, but the difference between 6LiF-7LiF and CR39 (in threshold energy, energy response, etc.) should be considered so that different types of radiation workers receive appropriate individual neutron dose monitoring.

ABSTRACT

Objective@#To clinically validate the feasibility and accuracy of cine images acquired through the multitasking method, with no electrocardiogram gating and free-breathing, in measuring left ventricular (LV) function indices by comparing them with those acquired through the balanced steady-state free precession (bSSFP) method, with multiple breath-holds and electrocardiogram gating. @*Materials and Methods@#Forty-three healthy volunteers (female:male, 30:13; mean age, 23.1 ± 2.3 years) and 36 patients requiring an assessment of LV function for various clinical indications (female:male, 22:14; 57.8 ± 11.3 years) were enrolled in this prospective study. Each participant underwent cardiac magnetic resonance imaging (MRI) using the multiple breath-hold bSSFP method and free-breathing multitasking method. LV function parameters were measured for both MRI methods. Image quality was assessed through subjective image quality scores (1 to 5) and calculation of the contrast-to-noise ratio (CNR) between the myocardium and blood pool. Differences between the two MRI methods were analyzed using the Bland–Altman plot, paired t-test, or Wilcoxon signed-rank test, as appropriate. @*Results@#LV ejection fraction (LVEF) was not significantly different between the two MRI methods (P = 0.222 in healthy volunteers and P = 0.343 in patients). LV end-diastolic mass was slightly overestimated with multitasking in both healthy volunteers (multitasking vs. bSSFP, 60.5 ± 10.7 g vs. 58.0 ± 10.4 g, respectively; P < 0.001) and patients (69.4 ± 18.1 g vs. 66.8 ± 18.0 g, respectively; P = 0.003). Acceptable and comparable image quality was achieved for both MRI methods (multitasking vs. bSSFP, 4.5 ± 0.7 vs. 4.6 ± 0.6, respectively; P = 0.203). The CNR between the myocardium and blood pool showed no significant differences between the two MRI methods (18.89 ± 6.65 vs. 18.19 ± 5.83, respectively; P = 0.480). @*Conclusion@#Multitasking-derived cine images obtained without electrocardiogram gating and breath-holding achieved similar image quality and accurate quantification of LVEF in healthy volunteers and patients.

ABSTRACT

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.
