ObjectivesTo systematically review the proportion of Tregs in peripheral blood of patients with ankylosing spondylitis (AS) and its relationship with Treg's diffrent phenotypes.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect case-control studies on peripheral Tregs of AS patients from inception to November 31st, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 61 case-control studies involving 2 466 AS patients and 1 879 controls were included. The results of meta-analysis showed that: the proportion of peripheral Tregs of patients with AS was significantly lower than that of the normal control (SMD=?0.905, 95%CI ?1.294 to ?0.517, P<0.000 1), and the proportion of Tregs in the disease-active group was significantly lower than that in disease-inactive group (SMD=?0.928, 95%CI ?1.431 to ?0.425, P<0.000 1). The proportion of CD4+CD25+FOXP3+Tregs and CD4+CD25+CD127low/?Tregs were lower in AS patients than that in control subjects (SMD=?2.547, 95%CI ?3.521 to ?1.573, P<0.000 1; SMD=?0.709, 95% CI ?1.056 to ?0.362, P<0.000 1). The proportion of Tregs defined by CD4+CD25low/?FOXP3+ was higher in AS patients (SMD=0.683, 95%CI 0.161 to 1.206, P=0.01). There was no significant difference betweew other phenotypes of Tregs groups.roups.ConclusionsThe reduction of Tregs may be one of the important reasons for the occurrence and development of AS, which may provide a new approach for the diagnosis and treatment of AS.
【Abstract】 Objective To explore the effectiveness of multiple joint arthroplasty in treating lower limb joint disease. Methods Between January 2000 and December 2007, 5 patients with lower limb joint disease (three or more joints were involved) were treated with total hip and knee arthroplasty. There were 3 males and 2 females, aged from 27 to 59 years (mean, 41.8 years). Two patients had ankylosing spondylitis and 3 had rheumatoid arthritis, whose hip and knee joints were involved. Four patients lost the ability of walking preoperatively, 1 patient could only walk with crutch. The Harris score was 24 ± 24 and the Hospital for Special Surgery (HSS) score was 28 ± 15. All patients underwent multiple joint arthroplasty simultaneously (2 cases) or multiple-stage (3 cases). Results Wounds healed by first intention in all patients. In 1 patient who had dislocation of the hip after operation, manipulative reduction and immobilization with skin traction were given for 3 weeks, and no dislocation occurred; in 2 patients who had early sign of anemia, blood transfusion was given. All patients were followed up 46-140 months with an average of 75 months. The patients could walk normally, and had no difficulty in upstairs and downstairs. The stability of the hip and knee was good, and no joint infection or loosening occurred. The Harris score was 88 ± 6 at last follow-up, showing significant difference when compared with the preoperative score (t=8.16, P=0.00); the HSS score was 86 ± 6, showing significant difference when compared with the preoperative score (t=13.96, P=0.00). Conclusion Multiple joint arthroplasty is an effective treatment method in patients with lower limb joint disease, which can significantly improve life quality of patients.
ObjectiveTo understand the self management status of patients with ankylosing spondylitis (AS). MethodsSixty inpatients and outpatients with AS in the Department of Rheumatology between December 2011 and December 2012 were selected as the study subjects by judgment sampling method. A self-made questionnaire was used for investigation. ResultsThe self-management skills of 10.0% of the patients were poor, 78.3% were moderate and 11.7% were fine. The self-management skills of functional training and keeping healthy lifestyle were relatively poor. The factors with a score from the highest to the lowest were:the mental self-management, symptom management, keeping healthy lifestyle, and the self-management of functional training. ConclusionsThe self-management skills of patients with ankylosing spondylitis range from moderate to relatively poor. Our results suggest that cultural factors and the course of disease may be the main influence factors for self-management skills of patients. Clinical medical personnel should know the situation of patients sufficiently, improve the processes of health education and take corresponding intervention measures to the lack of self management ability. By the above ways, we can improve the compliance obedience and the self-management skills of patients, then the patients' condition and living quality will be greatly improved.
ObjectiveTo evaluate the inflammatory markers in patients with ankylosing spondylitis (AS) or non-inflammatory diseases undergoing total hip arthroplasty (THA) and to ascertain the variation trend of perioperative inflammatory markers and the influence of inflammation markers after THA. MethodsBetween January 2013 and December 2014, 153 consecutive patients with AS were included. According to the range of motion (ROM), the patients were divided into ankylosis group (ROM: 0°; group A, n=92) and stiff group (ROM: 3-46°; group B, n=61); 120 noninflammatory diseases patients having no bacterial infection and undergoing primary THA served as non-inflammatory group (group C). The inflammatory markers including C-reactive protein (CRP), interleukin-6 (IL-6), and erythrocyte sedimentation rate (ESR) concentrations were measured before operation and at 1, 3, 5, and 7 days after operation, and the complication was observed. ResultsPerioperative serum CRP, IL-6, and ESR increased at first after operation, and then decreased in 3 groups. There were significant differences in CRP and ESR between at pre- and post-operation (P<0.05); the IL-6 at 1, 3, and 5 days after operation were significantly higher than that at preoperation (P<0.05), but no significant difference was found between at 7 days and at preoperation (P>0.05). CRP, IL-6, and ESR of group B were significantly higher than those of group A at preoperation (P<0.05); CRP and IL-6 of groups A and B were significantly higher than those of group C at preoperation and at 1 day after operation (P<0.05); ESR of groups A and B was significantly higher than that of group C at preoperation, and at 1 day and 3 days after operation (P<0.05); and no significant difference was shown among 3 groups at the other time points (P>0.05). No inflammatory activity or increased complication was observed. ConclusionAS and non-inflammatory diseases show similar change trend of inflammatory markers at preand post-operation. The inflammatory activity of AS has no significant effect on the changes of inflammation markers and does not increase the incidence of postoperative complications.
Objective To explore the MRI features of juvenile-onset ankylosing spondylitis (JoAS) for improving the level of diagnosis and therapy. Methods MRI findings of JoAS in 25 patients confirmed by clinical and laboratory results between October 2010 and September 2014 were retrospectively analyzed. Results There were a total of 67 locations of lesion in the 25 cases, including 19 in sacroiliac joint, 21 in hip joint, 6 in ischial tuberosity, 6 in crista iliaca, 9 in knee joint, 4 in ankle joint, and 2 in foot. MRI showed 63 locations with bone marrow edema, 36 with joint effusion, 26 with bone destruction, and 19 with enthesitis. Conclusions Bone marrow edema is the most common MRI manifestation of JoAS, and the main bone destruction is middle axis joint. MRI is sensitive but not specific to lesions, so differential diagnosis is needed and helpful.
ObjectiveTo evaluate the application and effectiveness of bilateral total hip arthroplasty and total knee arthroplasty in the treatment of severe inflammatory arthropathies. MethodsBetween September 2008 and September 2015, 31 patients with severe inflammatory arthropathies were treated with bilateral total hip arthroplasty and total knee arthroplasty. Of 31 cases, 22 were male and 9 were female with an average age of 30 years (range, 20 to 41 years); there were 15 cases of rheumatoid arthritis and 16 cases of ankylosing spondylitis with an average onset age of 14 years (range, 5-28 years); all 4 ankylosed joints were observed in 11 cases, 3 ankylosed joints in 2 cases, 2 ankylosed joints in 6 cases, 1 ankylosed joint in 1 case, and no ankylosed joint in 11 cases. Before operation, the hip range of motion (ROM) value was (17.82±28.18)°, and the knee ROM value score was (26.45±30.18)°; the hip Harris score was 29.64±11.58, and the hospital for special surgery (HSS) score was 27.07±11.04. The patients were grouped and compared in accordance with etiology and ankylosed joint. ResultsOne-stage arthroplasty was performed in 1 case, two-stage arthroplasty in 22 cases, three-stage arthroplasty in 7 cases, and four-stage arthroplasty in 1 case. The total operation time was 325-776 minutes; the total blood loss was 900-3 900 mL; the total transfusion volume was 2 220-8 070 mL; and the total hospitalization time was 21-65 days. The patients were followed up 12-94 months (mean, 51 months). The hip and knee ROM values, Harris score and HSS score at last follow-up were significantly improved when compared with preoperative ones (P < 0.05). The subjective satisfaction degree was good in 16 cases, moderate in 10 cases, and poor in 5 cases. Periprosthetic infection occurred in 2 cases (3 knees), joint stiffness in 3 cases (6 knees), joint instability in 1 case (1 knee), leg length discrepancy of > 2 cm in 2 cases, and flexion deformity of 10° in 1 case (1 knee). The hip and knee ROM values, Harris score and HSS score showed no significant difference between patients with ankylosing spondylitis and patients rheumatoid arthritis at last follow-up (P > 0.05). The hip and knee ROM values of the patients with ankylosed joint were significantly lower than those of patients with no ankylosed joint (P < 0.05); the Harris score and HSS score of the patients with ankylosed joint were lower than those of patients with no ankylosed joint, but no significant difference was found (P > 0.05). ConclusionA combination of bilateral hip and knee arthroplasty is an efficient treatment for severe lower extremities deformity, arthralgia and poor quality of life caused by inflammatory arthropathies. However, the postoperative periprosthetic infection and stiffness of knee are important complications influencing the effectiveness of operation.
Objective To assess the midterm follow-up outcomes of total hip arthroplasty (THA) for the treatment of patients with juvenile-onset ankylosing spondylitis (JAS). Methods The clinical data of 81 patients (127 hips) with JAS (age≤16 years, JAS group) and 267 patients (391 hips) with adult onset ankylosing spondylitis (AAS) (age>16 years, AAS group) between January 2004 and March 2018 were retrospectively analysed. The baseline demographics, clinical, radiographic, and laboratory parameters were collected. Before operation and at last follow-up, the overall disease activity [Bath ankylosing spondylitis disease activity index (BASDAI)] and function status [Bath ankylosing spondylitis functional index (BASFI)], hip subjective score [Harris hip score (HHS)] and objective score [12-item short form health survey (SF-12), including physical component score (PCS) and mental component score (MCS)], and patient satisfaction for THA were reviewed. The major orthopedic complications, including periprosthetic infection, dislocation, periprosthetic fractures, and poor incision healing, were also recorded during the follow-up period. Results The comparison of preoperative baseline parameters showed that the body mass, body mass index, age of onset, age of surgery, disease duration, and the proportion of combined smoking history in the JAS group were significantly lower than those in the AAS group (P<0.05), the proportion of bilateral surgeries, proportion of uveitis, proportion of combined family history, C-reactive protein, albumin, and preoperative BASFI were significantly higher than those in the AAS group (P<0.05). Both groups were followed up. The follow-up time in the JAS group was 29-199 months, with an average of 113 months; in the AAS group was 35-199 months, with an average of 98 months. Incisions in both groups healed by first intention. During the follow-up period, there were 1 case of periprosthetic fracture, 1 case of dislocation, and 1 case of ceramic fragmentation in the JAS group, 1 case of periprosthetic infection and 6 cases of periprosthetic fracture in the AAS group. There was no significant difference in the incidence of complications between the two groups (P>0.05). At last follow-up, the BASDAI, BASFI, SF-12 MCS, SF-12 PCS, and HHS score of the two groups were significantly improved when compared with those before operation (P<0.05); but there was no significan difference in the difference of the above parameters before and after operation and the patient satisfaction between the two groups (P>0.05). Conclusion The midterm follow-up outcomes of THA for the treatment of JAS patients were reliable. A low age at disease onset did not exert a significant negative effect on THA reconstruction for the treatment of ankylosing spondylitis.
Objective To investigate the effect of the morphological changes in the proximal femur on the prothesis selection in the total hip arthroplasty in the patients with ankylosing spondylitis. Methods The experimental group was composed of 13 patients (16 hips) with ankylosing spondylitis, which was treated with the total hip arthroplasty, and the control group was composed of 16 patients（19 hips）with non-ankylosing spondylitis，which was also treated with the total hip arthroplasty. In the two groups, the measurements of Singh index，canal flare index，morphological index of the cortex and cortical index were performed in the two groups. Results The results of the statistical analysis on Singh index，canal flare index, morphological index of the cortex and cortical index in the experimental group were 3.81±0.54, 2.63±0.41, 2.02±0.38 and 1.69±0.69, respectively, but 4.63±0.62, 3.03±0.27, 2.76±0.28 and 2.12±0.24, respectively in the control group. Therewas a significant difference in Singh index, canal flare index, and morphological index of the cortex between the two groups (Plt;0.05)，while there was no statistical difference in cortical index between the two groups (P＞0.05). The patientswith ankylosing spondylitis had more serious osteoporosis in their proximal femur. Conclusion Cemented femoral prosthesis should be used in the total hip replacement in patients with ankylosing spondylitis, and the revision total hip arthroplasty should be performed on patients with more serious osteoporosis.
Objective To assess the efficacy and safety of Etanercept for Ankylosing spondylitis. Methods We searched The Cochrane Library (Issue 4. 2008), MEDLINE (1966 to September 2008), EMBASE (1974 to September 2008), CBM (1978 to 2008), CNKI (1994 to 2008), VIP (1989 to 2008), and Wanfang (1999 to 2008). The quality of included studies was critically evaluated. Data analyses were performed with The Cochrane Collaboration’s RevMan 5.0 software. Results Seven randomized controlled trials with total of 949 patients met the included criteria. The metaanalysis showed the effective rate of ASAS 20 or ASAS 50 receiving Etanercept was significantly higher than in patients receiving placebo, while no significant differences were noted between the Etanercept and placebo group in other indices. There was no statistical significance among different dosages. Patient Injection-site reaction rate for Etanercept was higher than that for placebo. No significant differences were observed in other adverse effects. Conclusions Etanercept is safe and effective for patients with Ankylosing spondylitis, however, some trials included in the review were of poor quality, so we needed the multi-center, large-scale randomized controlled trials of higher quality and the same course of treatment to confirm this.
Objective To explore the safety and effectiveness of one-stage posterior eggshell osteotomy and long-segment pedicle screw fixation in the treatment of ankylosing spondylitis kyphosis combined with acute thoracolumbar vertebral fracture. Methods A clinical data of 20 patients with ankylosing spondylitis kyphosis combined with acute thoracolumbar spine fracture, who were treated with one-stage posterior eggshell osteotomy and long-segment pedicle screw fixation between April 2016 and January 2022, was retrospectively analyzed. Among them, 16 cases were male and 4 cases were female; their ages ranged from 32 to 68 years, with an average of 45.9 years. The causes of injury included 10 cases of sprain, 8 cases of fall, and 2 cases of falling from height. The time from injury to operation ranged from 1 to 12 days, with an average of 7.1 days. The injured segment was T11 in 2 cases, T12 in 2 cases, L1 in 6 cases, and L2 in 10 cases. X-ray film and CT showed that the patients had characteristic imaging manifestations of ankylosing spondylitis, and the fracture lines were involved in the anterior, middle, and posterior columns and accompanied by different degrees of kyphosis and vertebral compression; and MRI showed that 12 patients had different degrees of nerve injuries. The operation time, intraoperative bleeding, intra- and post-operative complications were recorded. The visual analogue scale (VAS) score and Oswestry disability index (ODI) were used to evaluate the low back pain and quality of life, and the American spinal cord injury association (ASIA) classification was used to evaluate the neurological function. X-ray films were taken, and local Cobb angle (LCA) and sagittal vertical axis (SVA) were measured to evaluate the correction of the kyphosis. Results All operations were successfully completed and the operation time ranged from 127 to 254 minutes (mean, 176.3 minutes). The amount of intraoperative bleeding ranged from 400 to 950 mL (mean, 722.5 mL). One case of dural sac tear occurred during operation, and no cerebrospinal fluid leakage occurred after repair, and the rest of the patients did not suffer from neurological and vascular injuries, cerebrospinal fluid leakage, and other related complications during operation. All incisions healed by first intention without infection or fat liquefaction. All patients were followed up 8-16 months (mean, 12.5 months). The VAS score, ODI, LCA, and SVA at 3 days after operation and last follow-up significantly improved when compared with those before operation (P<0.05), and the difference between 3 days after operation and last follow-up was not significant (P>0.05). The ASIA grading of neurological function at last follow-up also significantly improved when compared with that before operation (P<0.05), including 17 cases of grade E and 3 cases of grade D. At last follow-up, all bone grafts achieved bone fusion, and no complications such as loosening, breaking of internal fixation, and pseudoarthrosis occurred. Conclusion One-stage posterior eggshell osteotomy and long-segment pedicle screw fixation is an effective surgical procedure for ankylosing spondylitis kyphosis combined with acute thoracolumbar vertebral fracture. It can significantly relieve patients’ clinical symptoms and to some extent, alleviate the local kyphotic deformity.
