Therefore, we considered the lesion to be tuberculosis, and we performed erythrocyte sedimentation rate (ESR) (45 mm/h) and tuberculin purified protein derivative (PPD) (+) analyses, chest computed tomography (CT) (no obvious abnormalities), abdominal ultrasonography (ascites and some enlarged lymph nodes), an ascites test (exudate, ADA: 45 U/L), and colonoscopy (no tuberculosis or other lesions). This evidence concerns the gene ADA and tuberculosis.
