Effect of vitamin D levels on radiographic knee osteoarthritis and functional status.

OBJECTIVES: This study aims to investigate the effect of serum levels of 25 hydroxyvitamin D (25(OH)D) in patients with primary knee osteoarthritis (OA) and to assess its relationship with the radiographic grading and functional status. PATIENTS AND METHODS: Serum 25(OH)D levels were measured in 107 patients (90 females, 17 males; mean age 63.0±9.6 years; range, 40 to 86 years) with primary knee OA. Radiographic grading was based on the Kellgren-Lawrence Grading Scale and the Osteoarthritis Research Society International (OARSI) Atlas Grading Scale, while the functional status was assessed using the Lequesne indices and Turkish version of the Knee Injury and Osteoarthritis Outcome Score-Physical Function Short-Form (KOOS-PS). Pain was evaluated using the Visual Analog Scale for Pain (VAS-Pain). Data including age, sex, disease duration, body mass index (BMI), and pain severity were recorded. RESULTS: The mean 25(OH)D level was 13.4±10.6 ng/mL, and 90 patients (84.1%) had vitamin D deficiency. The presence of severe osteophytes was observed in 67 patients (62.6%) and 85 patients (79.4%) had Grade 2-3 joint space narrowing (JSN). The mean KOOS-PS and Lequesne scores were 40.1±12.3 and 12.9±3.6, respectively. There was no correlation between serum 25(OH)D levels and functional status. CONCLUSION: Our study results show that serum 25(OH)D level is not related to the severity of the radiographic knee OA grading or to the functional assessment. Age and BMI are the factors affecting the radiological knee OA severity, while age, sex, BMI, and pain severity are the main determinants of the functional status.

Coalition of trapezoid, capitate, and metacarpal: a case report.

Carpal coalition is a rare wrist anomaly. A coalition can be an isolated condition, but it can be observed as a component of a congenital syndrome as well. Carpal coalition is usually asymptomatic and detected incidentally. It is most frequently encountered as lunate-triquetral coalition, followed by capito-hamate coalition. Other coalition types are very rare. In this case report, we present a case in which the patient applied with complaints of pain, and in whom a coalition of capitate-trapezoid- second and third metacarpal was detected.

Clinic and ultrasound findings related to pain in patients with knee osteoarthritis.

The aim of this study was to determine clinical and US factors associated with pain in patients with knee osteoarthritis (OA). The study included 143 patients. Patients were divided into two groups: group 1 consisted of 94 patients with unilateral or bilateral knee pain ≥3 cm during physical activity for at least 48 h prior to inclusion, measured by the visual analog scale from 0 to 10 cm. Group 2 consisted of 49 patients with knee OA without knee pain at least 1 month prior to inclusion. In both knees, range of motion was measured by goniometry and anteroposterior, and lateral knee radiographs were taken during weight-bearing. OA grading was performed in accordance with the Kellgren-Lawrence criteria by a specialist in radiology experienced in this field. A knee ultrasound (US) examination was performed in all patients by a blinded radiologist. Women were more often symptomatic than men (p < 0.005). Patients in group 1 tended to have a higher body mass index (BMI; p<0.001). Radiographic grades III (52.1%) and II (37.2%) were most frequently found in group 1, whereas I (30.6%), II (46.9%), and III (22.4%) were found in group 2. When radiographic grades in both groups were compared, group 1 had greater radiographic grades than group 2 (p<0.001). US findings in group 1 were effusion of the suprapatellar pouch (72.3%), Baker's cyst (42.6%), protrusion of the anterior horn of the medial meniscus associated with medial collateral ligament displacement (9.6%), and loose body (9.6%). In group 2, the only US finding was Baker's cyst (6.1%). Regression analysis revealed that BMI, degree of knee flexion, and thickness of the quadriceps tendon were factors that were related with pain in the knee. Increased BMI, decrease in the degree of knee flexion, and decreased quadriceps tendon thickness are factors that increase the risk of pain in knee OA.

The relation between osteoporosis and vitamin D levels and disease activity in ankylosing spondylitis.

In this study, the relation between osteoporosis and vitamin D and the disease activity in patients with ankylosing spondylitis (AS) was investigated. A hundred patients with AS and 58 healthy individuals were included in the study. In addition to the routine blood and urine tests, serum 25-(OH)D3, parathormone (PTH), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), total calcium, ionized calcium, and phosphorous levels of all participants were also measured. Bone mineral density (BMD) measurements were performed at the anterior-posterior and lateral lumbar and femur regions. Anterior-posterior and lateral thoracic and lumbosacral radiography was performed on all participants. The disease activity was evaluated by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), functional status by Bath Ankylosing Spondylitis Functional Index (BASFI), and mobility by Bath Ankylosing Spondylitis Metrology Index (BASMI). In the patient group, BMD values obtained from the lateral lumbar and femur regions and serum vitamin D levels were lower than the control group. A negative relation was determined between the lateral lumbar BMD values and ESR, CRP, and BASDAI scores of patients with AS. The ESR, CRP levels, and BASMI scores of the AS patients with osteoporosis were significantly higher, when compared to patients without osteoporosis. The negative correlation between serum 25-(OH)D3 level and ESR, CRP levels did not reach a statistically significant level in patients with AS; the positive correlation between PTH levels and ESR, and the negative correlation between CRP and BASDAI also did not reach a statistically significant level. Vitamin D deficiency in AS may indirectly lead to osteoporosis by causing an increase in the inflammatory activity. The present authors believe that it would be beneficial to monitorize vitamin D levels together with BMD measurements in order to determine the patients under osteoporosis risk.

The relationship between enthesitis indices and disease activity parameters in patients with ankylosing spondylitis.

In this study, patients with ankylosing spondylitis (AS) were assessed both by patient and physician using two enthesitis indices and the relationship between these indices and disease activity parameters was investigated. The study involved 100 AS patients. The patients were evaluated with 10-cm visual analog scale (VAS) for spinal pain (VAS-S), peripheral joint pain (VAS-P), global assessment of patient, and global assessment of doctor. In the laboratory evaluations, the erythrocyte sedimentation rates (ESR) and serum C-reactive protein levels of the patients were determined. Bath AS disease activity index (BASDAI), Bath AS functional index (BASFI), Bath AS metrology index, and Bath AS radiology index were calculated. The severity of enthesitis was evaluated according to Mander enthesitis index (MEI) and Maastricht ankylosing spondylitis enthesitis score applied by both the patient (MASES-P) him/herself and the physician (MASES-D). There was a correlation between BASDAI and BASFI as well as MEI, MASES-D, and MASES-P indices (r = 0.447, r = 0.342, r = 0.663, r = 0.530, r = 0.464, and r = 0.435, respectively). No correlation between the laboratory parameters and enthesitis indices were detected. In multiple linear regression analysis, BASFI, VAS-S, and female gender (41.3%) were the best predictors of MEI-D, whereas BASFI, VAS-S, female gender, and ESR (32.5%) were the best predictors for MASES-D and BASFI (18.9%) was the best predictor of MASES-P. The assessment of simple and easily applicable MASES score by a patient may be expected to help the physician in clinical practice. When the disease activity of the patients with AS are evaluated, both BASDAI, the clinical importance of which has been confirmed in numerous studies and which is recommended by ASAS, and BASFI, which is valued by patients, should be considered.
