서론: 우리나라의 경제성장 및 보건 위생 향상에 따라 anti-HAV IgG 보유율이 감소하고 있으며 이에 따라 최근 급성 A형 간염이 급증하고 있다. 급성 A형 간염은 발열, 근육통, 오심, 구토 등 상기도 감염과 유사한 증상 및 황달, 상복부 통증을 나타내는 경우가 대부분이며 신경학 적 증상은 드문 것으로 알려져 있다. 이에 저자들은 심한 두통과 일시적인 시력소실을 동반한 신경학적 증상을 호소하는 급성 뇌병증을 보 인 급성 A형 간염 환자의 예를 보고하는 바이다. 증례: 평소 건강하였던 34세 남자 환자가 1일전부터 시작된 전신 쇠약감 및 근육통으로 내원하였다. 내원 당시 생체활력징후상 혈압 100/60 mmHg, 호흡수 20회/분, 맥박수 118회/분, 체온 36.0도였으며 말초혈액결사상 백혈구 7,150/mm3, 혈색소 19.1g/dL, 혈소판 185.000/mm3 였으며 총 빌리루빈 2.69 mg/dL, AST >2600 IU/L, ALT 2210 IU/L, ALP 176 IU/L, C-반 응단백질 47.0 mg/L으로 증가된 소견 보였다. HBs Ab 양성이었으나 HBs Ag, HCV Ab 와 PCR 음성이었으며 HAV-IgG/IgM Ab 음성이었 다. 복부 초음파 및 전산화 단층촬영상 간.비장 비대와 담낭벽 비후 소견이 보였다. 내원 4일째 AST 6564 IU/L, ALT 3993IU/L까지 상승하 였으며 내원 9일째 두통, 구토, 일시적인 시력소실을 보여 시행한 뇌척수액검사상 특이소견 없었으며 뇌자기공명영상 촬영에서 후두엽에 조영증강을 보이는 급성 뇌병증이 의심되는 소견을 보였다. 다시 시행한 HAV-IgG/IgM Ab검사상 모두 양성이었으며 경피적간침생검상 급 성 간염에 합당한 소견이었다. 보존적 치료 후 신경학적 증상 및 간수치 호전되었으며 외래에서 추적 관찰 중이다.

Background: Diagnosing bone and joint tuberculosis(TB) remains a challenge. A recently developed RD-1 gene-based assay for diagnosing TB infection shows promising results. We evaluated the diagnostic usefulness of this assay compared with conventional tests in patients with suspected bone and joint TB. Methods: All patients with suspected bone and joint TB were prospectively enrolled during a 1-year period. In addition to conventional tests for diagnosing TB, the IFN-γ-producing T-cell response to ESAT-6 and CFP-10 by ELISPOT assay using PBMC were performed. Final diagnosis in patients with suspected TB was classified by clinical category. Results: Forty patients with suspected bone and joint TB were enrolled. Of these patients, 22(55%) were classified with bone and joint TB including 17 osteomyelitis(12 confirmed + 4 probable + 1 possible), 3 TB arthritis(3 confirmed), and 2 prosthetic joint infection(2 confirmed). Baseline clinical characteristics and detailed data comparing diagnostic yield of PBMC assay with that of conventional tests for diagnosing TB are shown in Table 1. The sensitivities of the ELISPOT assay and tuberculin skin test(≥10mm) for active bone and joint TB were 100%(95% confidence interval[CI], 0.85-1.00) and 72%(95% CI, 0.47-0.90); and specificities were of 78%(95% CI, 0.52-0.94) and 88%(95% CI, 0.63-0.99) [p=0.013 and p=0.059, respectively]. Conclusion: The ELISPOT assay is a useful adjunct to the current tests for the diagnostic exclusion of active bone and joint TB.
