OBJECTIVE: This study examined the all-cause and sex-specific standardized mortality ratios (SMRs) in patients with spondyloarthropathy. METHODS: Studies examining the all-cause and/or cause-specific SMRs in patients with psoriatic arthritis (PsA) and ankylosing spondylitis (AS) compared to the general population were surveyed using MEDLINE, EMBASE, and Cochrane databases and manual searches. A meta-analysis of the all-cause and sex-specific SMRs in patients with rheumatic diseases was then performed. RESULTS: In total, 7 comparisons (5 PsA and 2 AS) from 6 reports met the inclusion criteria. Disease-specific meta-analysis showed that the pooled SMR was 1.299 (95% confidence interval [CI] 1.092–1.605, p=0.015) for PsA and 1.784 (95% CI 1.576–2.020, p < 0.001) for AS. Meta-analysis showed that the SMRs of PsA and AS were significantly higher (1.299 to 1.784 times) than those in the general population. The age- and sex-adjusted SMR was highest for AS (1.784), followed by PsA (1.299). Moreover, sex-specific meta-analysis showed that the all-cause SMRs were increased in female and male patients with PsA. On the other hand, mortality increased in male patients with AS (SMR 1.834), whereas there was no significant increase in female patients with AS. CONCLUSION: All-cause mortality is higher in patients with PsA and AS compared to the general population. On the other hand, the mortality was higher in males with AS but not in females.

STUDY DESIGN: Single-center retrospective study. PURPOSE: To clarify the clinical features of cervical myelopathy at the C1-2 level. OVERVIEW OF LITERATURE: Methods for distinguishing the affected level based on myelomere symptoms or dysfunction of the conducting pathway were established. However, no symptoms have been identified as being specific to the C1-2 level segment. METHODS: We evaluated 24 patients with cervical myelopathy due to spinal cord compression at the C1-2 level. Preoperative neurological assessment were investigated and compared with the rate and site of compression of the spinal cord using computed tomography-myelography. RESULTS: Impaired temperature and pain sensation were confirmed in 18 of the 24 patients with that localized to the upper arms (n=3), forearm (n=9), both (n=2), and whole body (n=4). Muscle weakness was observed in 18 patients, muscle weakness extended from the biceps brachii to the abductor digiti minimi in 10 patients, and in the whole body in 8 patients. Deep tendon reflexes were normal in 10 patients, whereas hyperactive deep tendon reflexes were noted in 14 patients. The rate of spinal cord compression was significantly higher in patients with perceptual dysfunction and muscle weakness compared with those with no dysfunction. However, no significant difference in the rate and site of compression was identified in those with dysfunction. CONCLUSIONS: Perceptual dysfunction and muscle weakness localized to the upper limbs was observed in 58% and 42% of patients, respectively. Neurological abnormalities, such as perceptual dysfunction and muscle weakness, were visualized in patients with marked compression.

Tumor necrosis factor (TNF) inhibitors are increasingly used in treatment of rheumatoid arthritis (RA), ankylosing spondylitis, psoriatic arthritis, and inflammatory bowel diseases including Crohn's disease and ulcerative colitis. Rarely, anti-TNF therapy is associated with neurological complications, including both central and peripheral nervous system disorders. To the best of our knowledge, only one case of infliximab-associated multifocal motor neuropathy with conduction block in a patient with spondyloarthropathy has been reported to date in Korea. Here, we report on the case of a 58-year-old Korean woman affected by RA who developed multifocal motor neuropathy after infliximab treatment.

OBJECTIVE: We examined the clinical relationship between human leukocyte antigen B27 (HLA-B27) and juvenile idiopathic arthritis (JIA). Additionally, we assessed the usefulness of the Assessment of SpondyloArthritis International Society (ASAS) criteria for diagnosing juvenile spondyloarthropathies (SpA). METHODS: We retrospectively reviewed medical records of 239 patients with JIA classified according to the International League of Associations for Rheumatology (ILAR) classification to analyze the features of the joint involvement site. Results were correlated with the presence of HLA-B27. After that, we classified the 239 JIA patients according to the ASAS criteria to diagnose juvenile SpA. The relationship between the ASAS criteria and a diagnosis of juvenile SpA was analyzed by a chi-squared test. RESULTS: Back pain was associated with HLA-B27 in boys (p=0.002) but not in girls (p=0.616). In both sexes, involvement of the small joints in the lower extremities was highly associated with HLA-B27 (p=0.001 for boys, p=0.021 for girls). In addition, HLA-B27 was associated with enthesitis (p=0.004 for boys, p=0.021 for girls). Eighty-seven (36.4%) patients with JIA fulfilled the ASAS criteria; 2 (0.8%) had axial SpA and 85 (35.6%) had peripheral SpA. HLA-B27 was the most significant factor for diagnosing juvenile SpA (sensitivity 80%, specificity 99.31%, positive likelihood ratio, 116). CONCLUSION: The ILAR criteria have some weaknesses for diagnosing HLA-B27-positive JIA patients in early stages. The use of the ASAS criteria for juvenile patients will enable pediatric rheumatologists to diagnose juvenile SpA patients earlier.

Owing to the ability of musculoskeletal ultrasound (US) to depict cross sectional images of synovial joint and related structures, US has become the most reliable tool for evaluation of arthritic activity of rheumatoid arthritis (RA). US can detect early synovitis, assess disease activity, and determine true remission in patients with RA. US also can detect early enthesitis in patients with spondyloarthropathies. In addition, US can provide a reliable tool for measuring skin thickness in patients with systemic sclerosis. With guidance of injection or aspiration, US can result in a better clinical outcome. Thus, educational needs and research networks are increasing. We present a review of rheumatology US, focusing on recent trends and advances.

Human immunodeficiency virus (HIV) infection is a global pandemic affecting more than 2.9 million people. Aside from opportunistic infections and malignancies, it involves multiple organs, resulting in many complications, and frequently shows various rheumatic manifestations. With improving survival of patients due to the development of highly active anti-retroviral therapy, the number of HIV-infected patients with rheumatic complications is certain to increase. However, reports on HIV induced rheumatic manifestations in Korean patients are limited. On the other hand, spondyloarthropathy is the most common form of inflammatory arthropathy in HIV associated rheumatic manifestations and is frequently accompanied by peripheral arthritis and enthesitis, while axial skeletal involvement is a rare presentation. Herein we report on a 46-year-old man with HIV infection presenting with an axial spondyloarthropathy who was treated successfully with nonsteroidal anti-inflammatory drug, sulfasalazine, and low dose steroid.

STUDY DESIGN: A retrospective study. PURPOSE: To investigate the surgical outcome for hemodialysis-related upper cervical lesions. OVERVIEW OF LITERATURE: Surgical outcome of lower cervical lesions in patients undergoing hemodialysis has been reported. However, surgical outcome for upper cervical lesions in hemodialysis patients is unclear. METHODS: Upper cervical lesions in nine patients undergoing hemodialysis were surgically treated. Mean age at surgery was 61.6 years (range, 52-68 years), and the mean follow-up period was 45.4 months (range, 2-98 months). Patients had undergone hemodialysis for an average of 25.3 years (range, 16-40 years) at surgery. Seven patients with destructive spondyloarthropathy (DSA) of the upper cervical spine were treated with atlantoaxial or occipitocervical fixation. Two patients with retro-odontoid pseudotumors were treated with C1 posterior arch resection alone. Japanese Orthopedic Association (JOA) scores for cervical myelopathy, postoperative complications, postoperative radiography, and preoperative and postoperative occipital pain were evaluated. RESULTS: Mean preoperative and postoperative JOA score was 3.7 and 8.1, respectively. The seven patients with DSA had severe preoperative occipital pain that disappeared postoperatively. Postoperative radiography showed solid bone union in DSA cases and no instability in pseudotumor cases. CONCLUSIONS: Satisfactory surgical outcome was observed for hemodialysis-related upper cervical lesions.

SAPHO syndrome, characterized by synovitis, acne, pustulosis, hyperostosis, and osteitis is rare compared to other spondyloarthropathies. It is also difficult to diagnose, and treatment methods have not yet been fully identified. Approximately 72% of patients are diagnosed with at least one other disease before a final diagnosis of SAPHO syndrome. In addition, SAPHO syndrome is subject to a delayed diagnosis period of 4.5 to 9.1 years. Medications such as non-steroidal anti-inflammatory drugs, disease-modifying anti-rheumatic drugs, and tumor necrosis factor inhibitors are used in treatment of SAPHO syndrome. Bisphosphonate is also used for refractory SAPHO syndrome; however, most reports on this relate to intravenous injection of medication. The authors experienced and subsequently reported on a case involving a patient with SAPHO syndrome accompanied by fracture and infection of the left second finger who was treated with the oral biphosphonate, alendronate.

Destructive spondyloarthropathy (DSA) has been reported in patients undergoing long-term hemodialysis. Cervical spinal lesions, including those of the upper cervical spine, are reported to be some of the most common. To our knowledge, we report for the first time, a case of atlanto-occipital subluxation requiring surgical treatment due to severe myelopathy and nuchal pain in a patient undergoing long-term hemodialysis. The patient was a 66-year-old woman who had undergone hemodialysis for 40 years. She visited our hospital due to an acute progression of gait disturbance and severe nuchal pain. Computed tomography showed posterior subluxation of the atlanto-occipital joints. DSA was also observed in the lower cervical spine. Magnetic resonance imaging showed spinal canal stenosis at both the upper and lower cervical levels. We performed Oc-C7 fixation, C1 laminectomy, and C3-C7 laminoplasty. We first recognized that the atlanto-occipital subluxation was caused by the extremely long-term, in this case, 40 years, hemodialysis.
