ABSTRACT

OBJECTIVE@#To explore the effectiveness of the combined anteversion angle technique in total hip arthroplasty (THA) for treating ankylosing spondylitis (AS) affecting the hip joint.@*METHODS@#A retrospective analysis was conducted on the clinical data of 73 patients with AS affecting the hip joint who underwent THA between August 2018 and August 2021. According to whether the combined anteversion angle technique was used in THA, the patients were divided into study group (37 cases, combined anteversion angle technique was used in THA) and control group (36 cases, traditional THA). There was no significant difference in baseline data such as gender, age, body mass index, disease duration, preoperative Harris score, range of motion (ROM), acetabular anteversion angle, acetabular abduction angle, femoral anteversion angle, and combined anteversion angle between the two groups ( P>0.05). The operation time, hospital stay, and complications of the two groups were recorded and compared. The Harris score and hip ROM were compared between the two groups before operation, at 1, 3, 6, 12 months after operation, and at last follow-up. The acetabular component anteversion angle, femoral component anteversion angle, acetabular component abduction angle, and component combined anteversion angle were measured postoperatively.@*RESULTS@#The operation time in the study group was significantly shorter than that in the control group ( P<0.05), and there was no significant difference in hospital stay between the two groups ( P>0.05). There was no intraoperative complication such as acetabular and proximal femoral fractures, neurovascular injuries in both groups, and the incisions healed by first intention. All patients were followed up 2-3 years, with an average of 2.4 years; there was no significant difference in the follow-up time between the two groups ( P>0.05). During the follow-up period, there was no complication such as hip dislocation, wound infection, delayed wound healing, deep venous thrombosis, and hip dislocation in both groups. The hip Harris score and ROM of the two groups gradually increased with time after operation, and the differences were significant when compared with those before operation ( P<0.05); the above two indicators of the study group were significantly better than those of the control group at each time point after operation ( P<0.05). Extensive bone ingrowth on the surface of the components could be observed in the anteroposterior X-ray films of the hip joint of the two groups at 12 months after operation, and the acetabular components was stable without femoral stem subsidence, osteolysis around the components, and heterotopic ossification. At last follow-up, the acetabular component anteversion angle, femoral component anteversion angle, and component combined anteversion angle in the study group were significantly superior to those in the control group ( P<0.05), except that there was no significant difference in the acetabular component abduction angle between the two groups ( P>0.05).@*CONCLUSION@#For patients with AS affecting the hip joint, the use of the combined anteversion angle technique during THA effectively promotes the recovery of hip joint function and enhances the postoperative quality of life of patients when compared to traditional THA.

ABSTRACT

Objective: To summarize the clinical, radiological characteristics, and prognosis of infectious sacroiliitis in children. Methods: A case-control study was conducted, including 12 cases of infectious sacroiliitis diagnosed in the Rheumatology and Immunology Department of the Children's Hospital affiliated with the Capital Institute of Pediatrics from June 2018 to June 2023. These cases comprised the case group. Concurrently, 28 cases of pediatric idiopathic arthritis involving the sacroiliac joint in the same department served as the control group. Basic patient information, clinical features, laboratory parameters, and clinical treatment outcomes for both groups were collected and analyzed. Independent sample t-tests and chi-squared tests were used for inter-group comparisons. Results: Among the 12 cases in the case group, there were 5 males and 7 females, with a disease duration of 0.8 (0.5, 1.2) months. Nine patients presented with fever, and 1 patient had limping gait. Human leukocyte antigen (HLA)-B27 positivity was observed in 1 case, and there was no family history of ankylosing spondylitis. In the control group of 28 cases, there were 19 males and 9 females, with a disease duration of 7.0 (3.0, 17.0) months. One patient (4%) had fever, and 14 cases (50%) exhibited limping gait. HLA-B27 positivity was found in 18 cases (64%), and 18 cases (64%) had a family history of ankylosing spondylitis. The case group had higher white blood cell count (WBC), neutrophil ratio, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels, as well as a higher proportion of unilateral involvement on magnetic resonance imaging and bone destruction on CT compared to the control group ((11.1±6.2)×109 vs. (7.3±2.3)×109/L, 0.64±0.10 vs. 0.55±0.12, 72 (34, 86) vs. 18 (5, 41) mm/1 h, 24.6 (10.1, 67.3) mg/L vs. 3.6 (0.8, 15.0) mg/L, 11/12 vs. 36% (10/28), 9/12 vs. 11% (3/28), t=2.90, 3.07, Z=-2.94, -3.28, χ2=10.55, 16.53, all P<0.05). Conclusions: Pediatric infectious sacroiliitis often presents as unilateral involvement with a short disease history. Elevated WBC, CRP, and ESR, as well as a high rate of bone destruction, are also common characteristics.

ABSTRACT

OBJECTIVE@#To explore the correlation of polymorphisms of AF4/FMR2 family genes and IL-10 gene with genetic susceptibility to ankylosing spondylitis (AS) and identify the high-risk factors of AS.@*METHODS@#This case-control study was conducted among 207 AS patients and 321 healthy individuals. The tag single nucleotide polymorphisms (SNPs) rs340630, rs241084, rs10865035, rs1698105, and rs1800896 of the AF4/FMR2 family gene and IL-10 gene of the AS patients were genotyped, and the distribution frequencies of the genotypes and alleles were analyzed to explore the relationship between different genetic models and AS and the gene-gene and gene-environment interactions.@*RESULTS@#Gender ratio, smoking history, drinking history, hypertension, erythrocyte sedimentation rate and C-reactive protein differed significantly between the case group and the control group (P < 0.05). The dominant model and recessive model of AFF1 rs340630, the recessive model of AFF3 rs10865035, and the recessive model of IL-10 rs1800896 were significantly different between the two groups (P=0.031, 0.010, 0.031, and 0.019, respectively). Gene-environment interaction analysis suggested that the interaction model incorporating AFF1 rs340630, AFF2 rs241084, AFF3 rs10865035, AFF4 rs1698105, IL-10 rs1800896, smoking history and drinking history was the best model. The genes related with AF4/FMR2 and IL-10 were enriched in the biological processes of AF4 super extension complex, interleukin family signal transduction, cytokine stimulation and apoptosis. The expression levels of AF4/FMR2 and IL-10 were positively correlated with immune infiltration (r > 0).@*CONCLUSION@#The SNPs of AF4/FMR2 and IL-10 genes are associated with the susceptibility to AS, and the interactions of AF4/FMR2 and IL-10 genes with the environmental factors contributes causes AS through immune infiltration.

ABSTRACT

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 T 11 in 2 cases, T 12 in 2 cases, L 1 in 6 cases, and L 2 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.

ABSTRACT

This study aimed to analyze the impact of traditional Chinese medicine(TCM) on the risk of re-admission for ankylosing spondylitis(AS) patients with dampness-heat syndrome. In this study, a telephone follow-up was conducted on 1 295 AS inpatients, and after screening and exclusions, 1 044 successfully followed-up patients were included. A retrospective cohort study was conducted using propensity score matching(PSM), and a Cox proportional risk model was employed to assess the effect of various factors on the risk of re-admission for AS patients with dampness-heat syndrome. Kaplan-Meier survival curves were used to analyze the effect of TCM intervention time on re-admission. The incidence rate of dampness-heat syndrome in AS patients was found to be 51.3% in this study. After 1∶1 PSM, 385 AS patients with dampness-heat syndrome and 385 AS patients without dampness-heat syndrome were included for analysis. The results indicated that the re-admission rate was higher for patients with dampness-heat syndrome compared with those without dampness-heat syndrome(P<0.05). AS patients with dampness-heat syndrome in the TCM group had a lower admission rate than those in the non-TCM group(P=0.01). The cox proportional risk model demonstrated that TCM was an independent protective factor, as it reduced the risk of re-admission by 35%(HR=0.35, 95%CI[0.26, 0.95], P<0.05). Moreover, the subgroup with high exposure(time to use Chinese medicine >12 months) had a significantly lower risk of re-admission than that with low TCM exposure(time to use Chinese medicine ≤12 months). The re-admission rate for AS patients with dampness-heat syndrome was higher than that without dampness-heat syndrome, and TCM was identified as a protective factor in reducing the risk of re-admission. Furthermore, a longer duration of TCM intervention was associated with a lower risk of re-admission.

ABSTRACT

@#Ankylosing spondylitis has been shown to be highly associated with HLA-B27 in Caucasian patients. This is also present in other ethnic groups. This study was conducted to determine the frequency distribution of HLA antigens in Filipinos and determine the association of ankylosing spondylitis. Twenty patients satisfying the criteria for ankylosing spondylitis and 192 unrelated controls were HLA-A and B typed. Blood from these subjects were typed using NIH lymphocyte microcyto-toxicity method. Of the unrelated controls, the frequencies of HLA A9 (w24), B40, A1, B5, Bw22 were increased and B13, B18, Bw35 were decreased. B27 had a frequency of 5.2%. A very significant high frequency of B27 (90%) was found in patients with ankylosing spondylitis with a very high relative risk of 163. A11 had a frequency of 55% with a relative risk of 3.37 which was not significant while B18 had an 18% frequency and a relative risk of 10.5 which was significant. This study reaffirms the high degree of association of ankylosing spondylitis with HLA B27 and suggests than B18 may be an additional genetic marker for this disease.

ABSTRACT

OBJECTIVE@#To investigate the changes in autophagy of mesenchymal stem cells (MSCs) from patients with ankylosing spondylitis and explore the mechanism for decreased autophagy in ASMSCs.@*METHODS@#MSCs collected from 14 patients with AS (ASMSCs) and from 15 healthy donors (HDMSCs) were cultured in the absence or presence of 25 ng/mL TNF-α for 6 h. Autophagy of the cells was determined by immunofluorescence staining of GFP-LC3B, and the results were confirmed by detecting the protein expressions of autophagy markers LC3 II/LC3 I and P62. The mRNA expressions of the related genes were detected using qRT-PCR, and the protein expressions of the autophagy markers and signaling pathway-related molecules were determined with Western blotting. TG100713 was used to block the PI3K/AKT/mTOR signal pathway, and its effect on autophagy of ASMSCs was evaluated.@*RESULTS@#ASMSCs showed significantly weaker GFP-LC3B puncta staining and lower protein expression levels of LC3 II/LC3 I but higher levels of P62 protein (P < 0.05), indicating a decreased autophagy capacity as compared with HDMSCs. TNF-α-induced ASMSCs showed significantly higher protein expressions of p-PI3K/ PI3K, p-AKT/AKT and p-mTOR/mTOR than HDMSCs (P < 0.05), suggesting hyperactivation of the PI3K/AKT/mTOR signaling pathway in ASMSCs. Blocking PI3K/AKT/mTOR signaling with TG100713 eliminated the difference in TNF-α-induced autophagy between HDMSCs and ASMSCs.@*CONCLUSION@#In patients with AS, hyperactivation of the PI3K/AKT/mTOR signaling pathway results in decreased autophagy of the MSCs and potentially contributes to chronic inflammation.

ABSTRACT

OBJECTIVE@#To explore the effect of robot-assisted internal fixation in lateral decubitus position for the treatment of ankylosing spondylitis (AS) complicated with thoracolumbar fractures.@*METHODS@#The clinical data of 26 patients with ankylosing spondylitis complicated with thoracolumbar fractures treated from January 2018 to June 2020 was retrospectively analyzed. According to different surgical methods, these patients were divided into observation group and control group. There were 8 patients in observation group, which were treated with robot-assisted percutaneous screw fixation in lateral decubitus position, including 4 males and 4 females, aged form 55 to 85 years old with an mean of (66.25±9.42) years, the course of disease was (4.00±0.76) days on average, 2 cases were T11 fracture, 2 cases were T12, 3 cases were L1 and 1 case was L2. And there were 18 patients in control group, which were treated with conventional percutaneous screw fixation in prone position, including 6 males and 12 females, aged from 48 to 81 years old with a mean of (61.22±9.53) years, the course of disease was (4.11±0.83) days on average, 2 cases were T10 injury, 3 cases were T11, 4 cases were T12, 7 cases were L1, and 2 cases were L2. The intraoperative blood loss, operation time, position time and postoperative neurological complications were compared between two groups. Postoperative visual analogue scale (VAS) at 1d and 3 months, and Oswestry Disability Index (ODI) before and 3 months after operation were observed. According to Gertzbein-Robbins standard to evaluate the accuracy of pedicle screw placement.@*RESULTS@#There was no nerve injury due to pedicle screw placement in both groups. The intraoperative blood loss in observation group and control group was (34.13±4.61) ml and (78.17±22.02) ml, operation time was(92.13±9.82) min and (106.22±11.55) min, position time was(10.00±2.14) min and (15.17±2.66) min, the differences was statistically significant(P<0.05);VAS of the two groups were (2.38±0.52) points and (4.56±0.98) points one day after surgery, respectively, with statistically significant differences (P<0.05), while VAS and ODI three months after surgery showed no statistically significant differences (P>0.05). The screw accuracy was 96.88%(62/64) in observation group and 81.48%(88/108) in control group, the difference was statistically significant(P<0.05).@*CONCLUSION@#Robot-assisted internal fixation in lateral decubitus position for the treatment of ankylosing spondylitis complicated with thoracolumbar fractures can shorten the position time and operation time, significantly improve the accuracy of internal fixation screw placement, relieve the early postoperative pain, reduce intraoperative blood loss and postoperative complications, and facilitate the fast track rehabilitation of patients.

ABSTRACT

To evaluate the efficacy and safety of Chinese patent medicines in the treatment of ankylosing spondylitis(AS) by frequency network Meta-analysis. Randomized controlled trials(RCTs)of Chinese patent medicines for AS were retrieved from CNKI, Wanfang, VIP, CBM, PubMed, EMbase and Cochrane Library databases from the time of database establishment to January 2021. The quality of the included RCTs was evaluated according to the Cochrane bias risk standard, and the data was analyzed by RevMan 5.3 and Stata/MP 15.1. A total of 12 kinds of Chinese patent medicines in 55 RCTs were included. According to Meta-analysis, in term of the effectiveness, the top three optimal medication regimens were Biqi Capsules, Yishen Juanbi Pills and Yaobitong Capsules combined with western medicine. The top three interventions to reduce the erythrocyte sedimentation rate(ESR)were Yishen Juanbi Pills, Xianling Gubao Capsules and Fufang Xuanju Capsules combined with western medicine. The top three interventions to reduce the C-reactive protein(CRP)were Biqi Capsules, Xianling Gubao Capsules and Fufang Xuanju Capsules combined with western medicine. In terms of the safety, top three optimal medication regimens were Total Glucosides of Paeony Capsules, Yishen Juanbi Pills, and Wangbi Tablets combined with western medicine. This network Meta-analysis suggests that Chinese patent medicines combined with conventional western medicine can effectively improve the joint pain symptoms of AS patients and reduce the acute inflammatory indicators, with high safety. However, the literature included in this study is generally of low methodological quality, and the conclusion needs to be verified by high-quality research.

ABSTRACT

ABSTRACT BACKGROUND: The terms Spondyloarthritis and spondyloarthropathy (Spa) are used to define a group of diseases with related clinical characteristics and genetics. AIM: To report the clinical and demographic characteristics of ankylosing spondylitis (AS) and undifferentiated spondyloarthritis (USpA) and to evaluate the frequency of cyclic citrullinated peptide antibody (anti-CCP) positivity. MATERIAL AND METHODS: Two hundred patients with USpA or AS, 100 control patients with a diagnosis of rheumatoid arthritis (RA) and 100 healthy volunteers were included. For each patient, their detailed medical histories, physical examination, whole blood counts, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), anti-CCP, routine biochemical tests, and HLA-B27 test results were evaluated. ASDAS and BASDAI scores and morning stiffness were used to evaluate the disease activity. RESULTS: The presenting symptom of 73 (73%) patients in the AS group and 58 (58%) patients in the USpA group was pain in axial joints. A family history of Spa was positive in 32 patients from both groups (32%). A positive HLA-B27 was found in 55% of the AS group and 25% of the USpA group (p < 0.01 for the difference between groups). The frequency of positive HLA-B27 was significantly higher in individuals with a family history of SpA (p = 0.022). A positive Anti-CCP was found in 56% of the RA group, a significantly higher frequency compared with other groups (p < 0.001). The frequency of positive Anti-CCP in patients in AS (9%) and USpA (6%) was significantly higher than in healthy controls (p < 0.001). CONCLUSIONS: The frequency of anti-CCP positivity was higher in SpA patients than in healthy controls.


INTRODUCCIÓN: Los términos espondiloartritis y espondiloatropatia (Spa) se usan para definir un grupo de enfermedades con características y genética relacionadas. OBJETIVO: Informar las características clínicas y demográficas de la espondilitis anquilosante (EA) y espondiloartritis indiferenciada (USpA) - y para evaluar la frecuencia de positividad del anticuerpo péptido citrulinado cíclico (anti-CCP). MATERIAL Y MÉTODOS: En este estudio observacional se incluyeron doscientos pacientes con USpA y EA, 100 pacientes control con diagnóstico de artritis reumatoide (AR) y 100 voluntarios sanos. Se evaluó la historia clínica, exámen físico, recuentos sanguíneos completos, velocidad de sedimentación globular (ESR), proteína C reactiva (PCR), anti-CCP, pruebas bioquímicas de rutina y resultados de la prueba HLA-B27. Para evaluar la actividad de la enfermedad se utilizaron las puntuaciones ASDAS y BASDAI y la rigidez matutina. RESULTADOS: El síntoma inicial de 73 (73%) pacientes en el grupo de EA y 58 (58%) pacientes en el grupo de USpA fue dolor en las articulaciones axiales. Treinta y dos pacientes de cada grupo (32%) tenían antecedentes familiares de SPA. HLA-B27 fue positivo en el 55% del grupo AS y el 25% del grupo USpA con una diferencia significativa entre los dos grupos (p < 0.001). La frecuencia de positividad HLA-B27 fue mayor en individuos con historia familiar de SpA (p = 0,02). Se encontraron anti-CCP positivos en el 56% del grupo con AR, una frecuencia significativamente mayor en comparación con otros grupos (p < 0,01). La frecuencia de anti-CCP positivo fue mayor los pacientes con AS (9%) y USpA (6%) que en el grupo sano (p < 0,001). CONCLUSIONES: La frecuencia de positividad anti-CCP fue mayor en los grupos de SpA en comparación con los grupos control sanos.

ABSTRACT

SUMMARY OBJECTIVE: Our study aimed to explore the potential risk factors for radiological hip joint involvement in patients with ankylosing spondylitis (AS). METHODS: This cross-sectional convey collected the clinical data, laboratory indicators, and radiographic data of patients with AS. Radiographic hip joint involvement was defined as a Bath Ankylosing Spondylitis Radiology Hip Index (BASRI-hip) score ≥2. Multivariate logistic regression analyses were conducted to explore the potential risk factors for radiological hip involvement in patients with AS. RESULTS: Based on BASRI-hip score, all enrolled 386 patients with AS were classified as patients involving with radiological hip joint involvement (BASRI-hip ≥2; n=203) and those without it (BASRI-hip ≤1; n=183). Mean age of enrolled patients with AS were 36.7±11.9 years, and 320 (82.9%) patients were male. Mean course of disease was 10.7±8.3 years, and 349 (90.4%) patients were with a positive HLAB27. Multivariate analyses indicated that Juvenile onset (onset age ≤16 years) (odds ratio [OR]=4.159, 95% confidence interval [CI], 1.779-9.721, p<0.001), body mass index (BMI) <18.5 kg/m2 (OR=1.986, 95%CI 1.187-3.323, p=0.009), continuous nonsteroidal anti-inflammatory drug (NSAID) use (OR=0.351, 95%CI 0.155-0.794, p=0.012), and bone mass below the expected range for age (Z score ≤-2) (OR=2.791, 95%CI 1.456-5.352, p=0.002) were independently associated with radiological hip joint involvement in patients with AS. CONCLUSIONS: The potential risk factors for radiological hip joint involvement were juvenile onset, lower BMI, and bone mass below the expected range for age. Furthermore, continuous NSAID use was the protective factor for radiological hip joint involvement in these population.

ABSTRACT

Doenças autoimunes são doenças universais, e os diagnósticos e tratamentos primários são habitualmente iniciados por clínicos em enfermarias ou ambulatórios, antes de serem encaminhados a especialistas. Além disso, pacientes em uso de biológicos internados em hospitais gerais têm sido cada vez mais frequentes na prática clínica. Conhecer o perfil de segurança, as indicações e os efeitos colaterais dessas drogas deve ser preocupação dos clínicos. Neste trabalho, foi realizada revisão de literatura sobre terapia biológica com rituximabe no tratamento das principais doenças autoimunes sistêmicas da prática clínica: artrite reumatoide, lúpus eritematoso sistêmico, vasculites relacionadas aos anticorpos anticitoplasma de neutrófilo, púrpura trombocitopênica imune e espondilite anquilosante. (AU)


AutoimmunAutoimmune diseases are universal diseases and primary diagnosis and treatment are typically initiated by internists in wards or outpatient clinics before being referred to specialists. In addition, patients on use of biologicals hospitalized in general hospitals have been increasingly common in clinical practice. Knowing the safety profile, the indications, and the side effects of these drugs should be a concern for the internists as well. In this study, the literature review was performed on biological therapy with Rituximab for treating the main systemic autoimmune diseases of clinical practice: rheumatoid arthritis, systemic lupus erythematosus, anti-neutrophil cytoplasmic antibody-associated vasculitides, immune thrombocytopenic purpura, and ankylosing spondylitis.

ABSTRACT

BACKGROUND@#Andersson lesions (ALs) are not uncommon in ankylosing spondylitis (AS). Plain radiography (PR) is widely used for the diagnosis of ALs. However, in our practice, there were some ALs in AS patients that could not be detected on plain radiographs. This study aimed to propose the concept of occult ALs and evaluate the prevalence and radiographic characteristics of the occult ALs in AS patients.@*METHODS@#A total of 496 consecutive AS patients were admitted in the Affiliated Drum Tower Hospital, Medical School of Nanjing University between April 2003 and November 2019 and they were retrospectively reviewed. The AS patients with ALs who met the following criteria were included for the investigation of occult ALs: (1) with pre-operative plain radiographs of the whole-spine and (2) availability of pre-operative computed tomography (CT) and/or magnetic resonance imaging (MRI) of the whole-spine. The occult ALs were defined as the ALs which were undetectable on plain radiographs but could be detected by CT and/or MRI. The extensive ALs involved the whole discovertebral junction or manifested as destructive lesions throughout the vertebral body. Independent-samples t test was used to compare the age between the patients with only occult ALs and those with only detectable ALs. Chi-square or Fisher exact test was applied to compare the types, distribution, and radiographic characteristics between detectable and occult ALs as appropriate.@*RESULTS@#Ninety-two AS patients with a mean age of 44.4 ± 10.1 years were included for the investigation of occult ALs. Twenty-three patients had occult ALs and the incidence was 25% (23/92). Fifteen extensive ALs were occult, and the proportion of extensive ALs was significantly higher in detectable ALs (97% vs. 44%, χ2 = 43.66, P < 0.001). As assessed by PR, the proportions of osteolytic destruction with reactive sclerosis (0 vs. 100%, χ2 = 111.00, P < 0.001), angular kyphosis of the affected discovertebral units or vertebral body (0 vs. 22%, χ2 = 8.86, P = 0.003), formation of an osseous bridge at the intervertebral space adjacent to ALs caused by the ossification of the anterior longitudinal ligament (38% vs. 86%, χ2 = 25.91, P < 0.001), and an abnormal height of the affected intervertebral space were all significantly lower in occult ALs (9% vs. 84%, χ2 = 60.41, P < 0.001).@*CONCLUSIONS@#Occult ALs presented with more subtle radiographic changes. Occult ALs should not be neglected, especially in the case of extensive occult ALs, because the stability of the spine might be severely impaired by these lesions.

ABSTRACT

BACKGROUND@#Circular RNA (circRNA) is a type of closed circular noncoding RNA (ncRNA), mostly formed by back-splicing or alternative splicing of pre-messenger RNA (mRNA). The aim of this study was to explore the expression profile of circRNA in peripheral blood mononuclear cells (PBMCs) of patients with ankylosing spondylitis (AS) and discover potential molecular markers of AS.@*METHODS@#The circRNA microarray technology was used to detect the expression of circRNAs in the peripheral blood of 6 patients with AS and 6 healthy controls (HC). To screen the differentially expressed circRNAs by fold change (FC) and P value, these differentially expressed circRNAs were analyzed by bioinformatics. In 60 cases of AS and 30 cases of HC, 4 circRNAs were subjected to real-time fluorescence quantitative polymerase chain reaction (RT-qPCR), and their correlation with various clinical indicators was analyzed. Finally, the receiver operating characteristic (ROC) curve was used to analyze their potential as AS diagnostic markers.@*RESULTS@#The microarray results showed that there were 1369 significantly differently expressed (P  1.5) circRNAs between the AS and HC groups (675 upregulated and 694 downregulated). The results of bioinformatics analysis suggested that they were mainly involved in "enzyme binding," "adenosine ribonucleotide binding," "MAPK signaling pathway", etc. The RT-qPCR results showed that the expressions of hsa_circRNA_001544 (U = 486.5, P < 0.05) and hsa_circRNA_102532 (U = 645, P < 0.05) were significantly different between the AS group and the HC group. The AS group was further divided into two subgroups: active AS (ASA) and stable AS (ASS). After analysis, it was found that compared with the HC group, hsa_circRNA_001544 was significantly increased in both ASA (U = 214, P < 0.05) and ASS groups (U = 273, P < 0.05), while hsa_circRNA_008961 (U = 250, P < 0.05) and hsa_circRNA_102532 (U = 295, P < 0.05) were only significantly increased in the ASA group. Furthermore, hsa_circRNA_012732 was significantly different between the ASA and ASS groups (U = 194, P < 0.05), and there was no statistical significance among the remaining groups. Correlation analysis results showed that hsa_circRNA_012732 was negatively correlated with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), high-sensitivity C-reactive protein (hsCRP), and globulin (GLOB) and positively correlated with lymphocyte count (LY), mean corpusular volume, and albumin (ALB), and hsa_circRNA_008961 was negatively correlated with platelet (PLT) count. ROC curve analysis showed that hsa_circRNA_001544 (95% CI = 0.610-0.831, P < 0.05) and hsa_circRNA_102532 (95% CI = 0.521-0.762, P < 0.05) were statistically significant, and their area under curve (AUC) values were 0.720 and 0.642, respectively.@*CONCLUSIONS@#There are differentially expressed circRNAs in PBMCs of AS patients, and they may be involved in the occurrence and development of AS. Among these differentially expressed circRNAs, hsa_circRNA_012732 has the potential to become an indicator of disease activity, and hsa_circRNA_001544 has the potential to become a molecular marker for AS diagnosis.

ABSTRACT

BACKGROUND@#Ankylosing spondylitis (AS) is a common chronic progressive rheumatic disease. The aim of this study was to explore factors influencing abnormal bone mineral density (BMD) in young and middle-aged patients with AS.@*METHODS@#From July 2014 to August 2018, hospitalized patients with AS and health examinees in the health examination center of our clinics, ranging in age from 20 to 50 years, were monitored. The BMD of the lumbar spine and femoral neck of AS patients and those of a healthy control group were measured using dual-energy X-ray absorption. The BMDs of AS patients were compared with respect to age, course of disease, iritis, smoking habits, sex, height, weight, body mass index (BMI), medication use, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), platelet volume, platelet count, uric acid (UA), alkaline phosphatase (AKP), and calcium ion levels. Single-nucleotide polymorphisms (SNPs) related to BMD were screened using genome-wide association analysis.@*RESULTS@#There was no statistical difference in the proportion of abnormal bone masses between the different body parts. The BMD of all bones in AS patients was lower than that in healthy controls (P < 0.05). Additionally, BMD was correlated with serum calcium and CRP in AS patients (P < 0.05), but not with age, platelet volume, platelet count, ESR, UA, AKP, height, weight, and BMI. The incidence of abnormal bone mass in AS patients was correlated with sex (P < 0.05), but not with medication use, iritis, or smoking. BMD of the lumbar spine in AS patients did not correlate linearly with the course of the disease, but BMD of the femoral neck correlated linearly with the course of the disease (P < 0.05). BMD was correlated with multiple SNPs in patients with AS. Lumbar BMD was correlated with rs7025373 and rs7848078. Femoral head BMD was correlated with 3:102157365, 3:102157417, rs1252202, rs1681355, rs3891857, rs7842614, and rs9870734, suggesting that genetic factors play a role in BMD in patients with AS.@*CONCLUSIONS@#The proportion of abnormal bone mass in AS patients was higher than that in healthy individuals of the same age. The factors related to BMD in patients with AS are gender, CRP, and blood calcium. The BMD of the femoral neck of AS patients decreases with the course of the disease, but BMD of the lumbar spine is not related to the course of the disease. BMD in AS patients is associated with multiple SNPs.

ABSTRACT

Introducción: La espondilitis anquilosante es un trastorno inflamatorio progresivo que afecta el esqueleto axial, inclusive las articulaciones sacroilíacas; el riesgo de sufrir una fractura se cuadruplica (10% a los 10 años de enfermedad), la tasa de demora del diagnóstico es alta. La rigidez y la osteoporosis son factores clave para sufrir estas lesiones. La tomografía computarizada y la resonancia magnética cumplen un rol diagnóstico fundamental. La descompresión y la fijación quirúrgica es el tratamiento de elección actual. Se presenta una serie de casos con el objetivo de considerar las dificultades diagnósticas, describir las lesiones y la decisión terapéutica, analizar la presentación de complicaciones y realizar una actualización bibliográfica. materiales y métodos: Estudio multicéntrico retrospectivo de una serie de casos con 6 pacientes. Resultados: Seis hombres, edad promedio 58.1 años. Cuatro habían sufrido una caída desde la posición de pie. El tiempo promedio hasta el diagnóstico fue de 12.8 días. Los sectores más afectados fueron el torácico y el lumbar, con un mecanismo predominante en hiperextensión. Cuatro pacientes recibieron tratamiento quirúrgico. Conclusiones: Los pacientes con espondilitis anquilosante tienen un riesgo más alto de sufrir una fractura por traumas de baja energía. La demora para llegar al diagnóstico fue de 12.8 días. La cirugía con fijaciones largas y liberación por vía posterior es el tratamiento más utilizado. No se observaron complicaciones después del tratamiento. Nivel de Evidencia: IV


Introduction: Ankylosing Spondylitis (AS) is a progressive inflammatory disorder that affects the axial skeleton including the sacroiliac joints. Patients are 4 times more likely to suffer a fracture (10% at 10 years of illness), and there is a high percentage of delay in diagnosis. Stiffness and osteoporosis are key to suffering these injuries. CT and MRI scannings play a fundamental role in diagnosis. The current choice for treatment is decompression and surgical fixation. A series of cases is presented in order to: consider diagnostic difficulties; describe the injuries and therapeutic decision; analyze the presentation of complications andcarry out a bibliographic update. Materials and Methods: This is a retrospective multicenter study of a case series of 6 patients. Results: Six males with an average age of 58.1 years. Four presented a fall from the standing position. The delay in diagnosis was 12.8 days on average. The most affected areas were thoracic and lumbar, with a predominant mechanism of hyperextension. Four patients underwent surgery. Discussion: Fractures in patients with AS are frequent complications related to osteoporosis. CT is the sensitive and specific method for diagnosing the lesion. The current literature supports the need for subsequent surgical treatment. Conclusions: AS carriers are more at risk of suffering a low-energy trauma fracture. A delay of 12.8 days in diagnosis. Surgical treatment, with long fixations and posterior release, is the most widely used treatment. We have not observed post treatment complications. Level of Evidence: IV

ABSTRACT

Abstract Spondyloarthritis (SpA) is a group of chronic inflammatory systemic diseases characterized by axial and/or peripheral joints inflammation, as well as extra-articular manifestations. Over some decades, nonsteroidal anti-inflammatory drugs (NSAIDs) have been the basis for the pharmacological treatment of patients with axial spondyloarthritis (axSpA). However, the emergence of the immunobiologic agents brought up the discussion about the role of NSAIDs in the management of these patients. The objective of this guideline is to provide recommendations for the use of NSAIDs for the treatment of axSpA. A panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis of randomized clinical trials for 15 predefined questions. The Grading of Recommendations, Assessment, Development and Evaluation methodology to assess the quality of evidence and formulate recommendations were used, and at least 70% agreement of the voting panel was needed. Fourteen recommendations for the use of NSAIDs in the treatment of patients with axSpA were elaborated. The purpose of these recommendations is to support clinicians' decision making, without taking out his/her autonomy when prescribing for an individual patient.(AU)

ABSTRACT

Abstract Background: Hyperhomocysteinemia is associated with autoimmune diseases such as ankylosing spondylitis (AS), systemic lupus erythematosus (SLE), and rheumatoid arthritis (RA). Current findings regarding plasma/serum homocysteine (HCY) levels in AS patients are inconsistent. This study aims to systematically evaluate the association between circulating HCY levels and AS. Methods: Online electronic databases (PubMed, Web of Science, Embase, ScienceDirect, China National Knowledge Infrastructure (CNKI), and Wanfang data) were used to retrieve all relevant articles published up to May 7, 2020. The pooled standardized mean difference (SMD) with 95% confidence interval (CI) was calculated using the random-effect model, Stata16 software. Results: Nine articles containing 778 AS patients and 522 controls were included in this meta-analysis. No significant differences in HCY levels were found between AS and control groups (pooled SMD = 0.46, 95% CI = − 0.30 to 1.23, P = 0.23). However, subgroup analysis suggested that HCY levels were significantly higher (P < 0.05) in the AS group treated with methotrexate (MTX) compared with the control group. In contrast, HCY levels were significantly (P < 0.05) lower in the AS group receiving anti-TNF-α treatment compared with the control group. No significant differences were detected between HCY levels and disease activity scores (Bath AS disease activity index, BASDAI), and methylenetetrahydrofolate reductase (MTHFR) C677T genotype. Conclusion: This meta-analysis indicates that HCY levels are similar between AS and controls, and do not correlate with disease activity. However, different medical treatments cause fluctuations of circulating HCY levels in AS patients. Further and larger-scale studies are needed to confirm these findings. Trial registration: This study was registered at international prospective register of systematic reviews (PROSPERO), registration number: CRD42020184426.(AU)

ABSTRACT

Abstract Large epidemiologic and clinical estimates of spondyloarthritis (SpA) in Latin America are not available. In this narrative review, our goal was to descriptively summarize the prevalence and features of SpA in Latin America, based on available small studies. A review of peer-reviewed literature identified 41 relevant publications. Of these, 11 (mostly based on Mexican data) estimated the prevalence of SpA and its subtypes, which varied from 0.28 to 0.9% (SpA), 0.02 to 0.8% (ankylosing spondylitis), 0.2 to 0.9% (axial SpA), and 0.004 to 0.08% (psoriatic arthritis). Demographic and/or clinical characteristics were reported in 31 of the 41 publications, deriving data from 3 multinational studies, as well as individual studies from Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, Peru, Uruguay, and Venezuela. Data relating to treatment, disease manifestations (articular and extra-articular), and comorbidities were summarized across the countries. Available data suggest that there is a variability in prevalence, manifestations, and comorbidities of SpA across Latin America. Basic epidemiologic and clinical data are required from several countries not currently represented. Data relating to current treatment approaches, patient outcomes, and socioeconomic impact within this large geographic region are also needed.(AU)
