ABSTRACT

Objective@#. There is a debate over the relevance of ultrasound abnormalities to the pain, functional impairment, and radiologic severity in hand osteoarthritis (OA). This study aims to determine the association between ultrasound abnormalities and clinical, functional, and radiographic measures in hand OA. @*Methods@#. A total of 66 patients was consecutively enrolled. All patients with gray-scale synovitis, joint effusion, and osteophytes were examined by ultrasound for 20 hand joints. Radiographic changes in both hands were evaluated by the Kellgren-Lawrence (K-L) grading system and were described as total radiographic severity score and number of affected joints. Other measures were also assessed, including each patient’s visual analogue scale for pain, the Functional Index for Hand Osteoarthritis for functional disability, and grip and pinch strength for hand muscle strength. @*Results@#. In total, 10 patients with gray-scale synovitis, 35 with joint effusion, and 66 with osteophytes were detected in hand OA scans on ultrasound. Osteophytes on ultrasound were significantly associated with total radiographic severity score and number of affected joint (r=0.293, p=0.003 and r=0.336, p<0.001, respectively). In addition, there were weak associations of synovitis and joint effusion with radiographic changes. Patients with higher total radiographic severity score showed larger number of ultrasound-detected abnormalities, such as synovitis, joint effusion, and osteophytes (p=0.011, p=0.002, and p<0.001, respectively). @*Conclusion@#. This study shows that ultrasound findings, especially osteophytes, were associated with radiographic changes based on K-L grade, but not clinical and functional status in hand OA.

ABSTRACT

OBJECTIVE@#The aim of this study was to determine the relationships of serum and urine uric acid with severity or activity in knee osteoarthritis (OA).@*METHODS@#A total of 42 patients with knee OA was enrolled, together with 58 healthy controls. Serum uric acid and spot urine uric acid levels were assessed for all patients. The severity and activity of knee OA were assessed by musculoskeletal ultrasound (MSUS) and plain radiography of the knee joint. Ultrasonographic abnormalities in knee OA includedsynovial hypertrophy, suprapatellar effusion, cartilage degradation, and osteophyte formation. Kellgren-Lawrence (K-L) grade was used to evaluate radiological progression of knee OA.@*RESULTS@#Patients with K-L grade III had a higher urine uric acid/creatinine ratio compared to those with K-L grade I (p=0.043). Patients with synovial hypertrophy had higher serum uric acid level compared to those without synovial hypertrophy (p=0.016). The urine uric acid/creatinine ratio was higher in patients with cartilage degradation compared to those without cartilage degradation (p=0.022). Serum uric acid was significantly associated with synovial hypertrophy thickness (r=0.375, p=0.018) but not with cartilage thickness after adjusting for age and body mass index. Lower urine uric acid was related with knee OA compared to healthy controls (odds ratio=0.974, 95% confidence interval 0.954~0.994, p=0.013).@*CONCLUSION@#The results of our study suggest that serum and urine uric acid reflects synovial inflammation based on MSUS and radiographic progression and then is associated with the pathogenesis of knee OA.

ABSTRACT

BACKGROUND: The objective of this study was to identify the effects of mycophenolate mofetil (MMF) on non-renal manifestations in systemic lupus erythematosus (SLE). METHODS: The study population comprised 439 SLE patients from the Korean Lupus Network registry who were followed up annually and completed the baseline survey and two follow-up visits from 2014 to 2018. Disease activity, laboratory markers, and clinical manifestations including mucocutaneous lesions, arthritis, serositis, neurological disorders, and hematologic/immunologic abnormalities were assessed. All variables by group (MMF and non-MMF) effects with time (baseline, 1st follow-up, and 2nd follow-up) were analyzed by generalized estimation equation. RESULTS: Seventy-two patients were treated with MMF. There was significant difference in frequencies of malar rash, arthritis, renal disorder, and hematologic disorder between MMF and non-MMF groups in total SLE patients. In subgroup analysis of hematologic abnormalities in total patients, frequency of leukopenia was significantly different between the two groups during follow-up (P = 0.001), but frequencies of hemolytic anemia, lymphopenia, and thrombocytopenia were not. In addition, frequencies of leukopenia in patients without lupus nephritis were significantly decreased in MMF group compared to non-MMF group (P = 0.012). CONCLUSION: This study showed that MMF might be a beneficial treatment for hematologic abnormalities, especially leukopenia, in SLE.

ABSTRACT

Calcium pyrophosphate dihydrate crystal deposition disease is associated with an acute mono- or pauciarthritis, termed "pseudogout" in elderly patients, involving a large joint (including the knees, ankles) or a chronic arthropathy manifesting as mild joint pain and stiffness. Pseudogout is a crystal-deposition disease of peripheral joints, usually encountered in elderly patients. However, acute presentation of pseudogout around the odontoid process comprises a "crowned-dens" appearance, and requires contemplation of differential diagnoses. We recently experienced a case of pseudogout in the cervical spine presenting with fever and acute neck pain that was successfully treated with a colchicine and low-dose oral steroid. We reported this case with a review of the relevant literature.

ABSTRACT

OBJECTIVE: The aim of this study is to analyze the capacity of three demographic variables - age, sex, and formal education level - as well as disease duration to explain variation in 7 Core Data Set variables and 4 indices used to assess rheumatoid arthritis (RA), in a cohort of Korean patients seen in usual care. METHODS: All RA Core Data Set measures were collected in usual care of 397 RA patients, including tender/swollen joint counts (TJC, SJC) 28, physician global estimate of status, erythrocyte sedimentation rate, C-reactive protein, and a multidimensional health assessment questionnaire to assess physical function, pain, and patient global estimate of status (PATGL). Four indices were computed: disease activity score with 28 joint count (DAS28), simplified disease activity index (SDAI), clinical disease activity index (CDAI), and routine assessment of patient index data 3 (RAPID3). Descriptive statistics and multivariate generalized linear models were used in data analysis. RESULTS: Patients with lower education had higher scores, indicating greater severity, for all 7 Core Data Set measures and 4 indices (significant for TJC, function, pain, PATGL, DAS28, SDAI, CDAI, RAPID3). In a series of regressions that included age, sex, disease duration, and education, formal education level was the only significant variable to explain variation in TJC, pain, PATGL, physician global estimate of status (DOCGL), DAS28, SDAI, CDAI, and RAPID3. CONCLUSION: Significant associations with education were found in Korean RA patients according to most RA Core Data Set measures and 4 indices. Education was more likely than age, sex, or disease duration to explain variation in most measures and indices.
