Cross-cultural adaptation and validation of the Behcet’s Disease Current Activity Form in Korea

Background/Aims: This study was undertaken to perform a cross-cultural adaptation of the Behcet’s Disease Current Activity Form (BDCAF, version 2006) questionnaire to the Korean language and to evaluate its reliability and validity in a population of Korean patients with Behcet’s disease (BD). Methods: A cross-cultural study was conducted among patients with BD who attended our rheumatology clinic between November 2012 and March 2013. There were 11 males and 35 females in the group. The mean age of the participants was 48.5 years and the mean disease duration was 6.4 years. The first BDCAF questionnaire was completed on arrival and the second assessment was performed 20 minutes later by a different physician. The test-retest reliability was analyzed by computing κ statistics. Kappa scores of > 0.6 indicated a good agreement. To assess the validity, we compared the total BDCAF score with the patient’s/clinician’s perception of disease activity and the Korean version of the Behcet’s Disease Quality of Life (BDQOL). Results: For the test-retest reliability, good agreements were achieved on items such as headache, oral/genital ulceration, erythema, skin pustules, arthralgia, nausea/vomiting/abdominal pain, and diarrhea with altered/frank blood per rectum. Moderate agreement was observed for eye and nervous system involvement. We achieved a fair agreement for arthritis and major vessel involvement. Significant correlations were obtained between the total BDCAF score with the BDQOL and the patient’s/clinician’s perception of disease activity p < 0.05). Conclusions: The Korean version of the BDCAF is a reliable and valid instrument for measuring current disease activity in Korean BD patients.

Validation and reliability of a Behcet’s Syndrome Activity Scale in Korea

Background/Aims: We prepared a cross-cultural adaptation of the Behcet’s Syndrome Activity Scale (BSAS) and evaluated its reliability and validity in Korea. Methods: Fifty patients with Behcet’s disease (BD) who attended the Rheumatology Clinic of Gachon University Gil Medical Center were included in this study. The first BSAS questionnaire was administered at each clinic visit, and the second questionnaire was completed at home within 24 hours of the visit. A Behcet’s Disease Current Activity Form (BDCAF) and a Behcet’s Disease Quality of Life (BDQOL) form were also given to patients. The test-retest reliability was analyzed by intraclass correlation coefficients (ICC). To assess the validity, the total BSAS score was compared with the BDCAF score, the patient/physician global assessment, and the BDQOL by Spearman rank correlation. Results: Twelve males and 38 females were enrolled. The mean age was 48.5 years and the mean disease duration was 6.7 years. Thirty-eight patients (76.0%) returned the questionnaire by mail. For the test-retest reliability, the two assessments were significantly correlated on all 10 items of the BSAS questionnaire (p < 0.05) and the total BSAS score (ICC, 0.925; p < 0.001). The total BSAS score was statistically correlated with the BDQOL, BDCAF, and patient/physician global assessment (p < 0.01). Conclusions: The Korean version of BSAS is a reliable and valid instrument to measure BD activity.

Clinical phenotypes of Korean patients with Behcet disease according to gender, age at onset,and HLA-B51

Background/Aims The clinical manifestations of Behcet disease (BD) have been reported to differ according to country, region, and race. Gender, onset age, and human leukocyte antigen (HLA)-B51 have also been known as the factors that influence the clinical features of BD. The aim of this study is to investigate the clinical phenotypes of Korean patients who visited the rheumatology clinic with BD with respect to gender, onset age, and HLA-B51. Methods Total 193 Korean patients (129 females and 64 males) fulfilling the international criteria for BD were retrospectively assessed. Results The mean age at disease onset and disease duration of the BD patients were 32.2 ± 11.1 and 14.2 ± 9.3 years, retrospectively. Females suffered more frequently from genital ulcers (90.7% vs. 75.0%, p < 0.01), peripheral arthritis (67.4% vs. 43.8%, p < 0.01), and inf lammatory low back pain (38.8% vs. 23.4%, p = 0.03) than males, while skin involvement was more frequent in males than in females (90.6% vs. 75.2%, p = 0.01). The patients with late onset of BD (> 40 years) suffered from neurologic involvement (15.9% vs. 4.2%, p = 0.007) more frequently than those with early onset of BD. The patients with HLA-B51 showed earlier onset of disease than without HLA-B51 (28.3 ± 11.4 years vs. 33.8±11.6 years, p = 0.02) and the neurologic and gastrointestinal involvements were more frequent in the patients without HLA-B51 than with HLA-B51 (17.2% vs. 2.5%, p = 0.02 and 20.7% vs. 2.5%, p = 0.01, respectively). Conclusions The clinical phenotypes in Korean patients with BD may be influenced by gender, onset age and HLA-B51.

Mean platelet volume as a marker for differentiating disease flare from infection in Behçet's disease

The aim of this study was to investigate the association between mean platelet volume (MPV) and clinical manifestations, disease activity or infection in patients with Behçets disease (BD).

Infliximab for refractory oral ulcers

Recurrent oral ulcer (ROU) is a common condition that significantly impacts quality of life. It is often related to systemic diseases, such as Behçets disease (BD), Crohns disease, and ulcerative colitis. Treatment of ROU depends on its severity: from topical agents for mild cases to systemic agents, such as corticosteroids, azathioprine, or other immunosuppressants for severe cases. Recently, good results have been reported with infliximab in refractory ROU. However, the optimal dosage and treatment duration have not been determined and the cost and potential side effects should be considered. We report on four patients who received a single-dose infliximab for refractory ROU. Two patients had refractory ROU with no underlying disease; one of them had soft palate perforation accompanied by severe oral ulcers. The two other patients had ROU of BD without major organ involvement. All patients received a single infusion of infliximab and an additional infusion was given on demand in one patient. Infliximab showed a rapid, good response in three patients and was also effective in improving the acute inflammation in the perforation of the soft palate, which had been resistant to conventional therapies. These effects diminished over a few weeks, but the ROU were tolerable and it was not necessary to increase steroids or add another medicine for about 1 year. We suggest that a single infusion of infliximab can be considered for refractory ROU.

Successful Treatment of Concurrent Mucormycosis and Diffuse Alveolar Hemorrhage in a Patient With Newly Diagnosed Systemic Lupus Erythematosus

©2018 Turkish League Against Rheumatism. All rights reserved. Infection is often complicated with systemic lupus erythematosus (SLE) and is one of the leading causes of death in SLE patients.1 When SLE flare coexisting with serious infection is suspected, intensive immunosuppressive therapy is usually a challenge. Mucormycosis is a rare and rapidly progressing infection with high mortality. Diffuse alveolar hemorrhage (DAH) is also one of the rare and serious manifestations in SLE.2,3 We experienced an extremely rare case of SLE that was initially presented with DAH and mucormycosis concurrently.
