Accelerated inactivation of corticosteroids following rifampicin therapy has beenrecognized. We observed nonresponsiveness to prednisolone treatment during rifampicinadministration in a case of systemic lupus erythematosus with diffuse alveolitis andconcomitant apical tuberculosis.A 51 year-old woman complained in September 1980, of polyarthralgia and butterflyerythema of the face. From typical clinical manifestations and positive serological tests, systemic lupus erythematosus was diagnosed and treatment with prednisolone was startedat a local hospital. To prevent exacerbation of old apical tuberculosis, isoniazid 0.2 gdaily was also administered. Good response was obtained for an initial few months butdyspnea, diffuse pulmonary infiltrates appeared following prednisolone decrement.She was transfered to our hospital in August 1981. On admission, she had a few skinulcers in bilateral hands and pigmentations over the surface of shoulder, elbow and knee.Velcro rales were audible over the lung base. No lymphadenopathy was detected.Laboratory examination revealed positive RA test, antinuclear and anti-DNA antibody. Thyroid test and microsome test were also positive, but LE test, RNP antibody, SMantibody were negative. C4, CH50 were normal but C3 was decreased. Chest X-Prevealed diffuse reticular shadows in bilateral middle and lower lung field and nodularconsolidation in right apical region. Although tubercle bacilli was negative in sputum, exacerbation of tuberculosis were suspected radiologically. Histological specimen obtained by transbronchial lung biopsy from the left lung showed mild interstitial thickening of alveoli with mononuclear cell infiltration.Prednisolone was increased from daily dose of 5mg to 80mg and 450mg of rifampicin, 1, 000mg of ethambutol were added, but no response was obtained. In December 1981, prednisolone was altered to equivalent dose of betamethasone but minimal improvementwas observed.After quitting rifampicin on January 1982, dramatic improvement in symptoms, laboratory data and chest roentgenogram was achieved. Although pharmacokineticstudies were not performed, we feel that the circumstantial evidence suggests strongly toincreased metabolism of prednisolone by rifampicin-induced microsomal enzymes.

HPLC-UV法でプリン, ピリミジン代謝産物, アロプリノールとオキシプリノールの血中, 尿中濃度測定法について検討した. 溶媒には1%メタノール含有リン酸緩衝液(10mmol/ℓ, pH5.0), μBondapakC18カラムを用い, 13物質の同時分離が可能と考えられた. 再現性は連続測定にて1.56μmol/ℓ, allopurinol; 変動係数(CV)2.76%から50.0μmol/ℓ, pseudouridine; 変動係数(CV)0.38%と良好であった. 除蛋白法として限外濾過法を用いた血漿濃度測定では, 回収率はuric acid: 101.7-107.5%, hypoxanthine: 90.4-102.8%, xanthine: 95.9-99.5%, oxipurinol: 104.4-107.1%, allopurinol: 97.4-103.4%と良好であった. 各物質の同定は, retention time, 吸光度比, 純物質添加法と酵素反応法にて行った. また同条件下で, pseudouridine, uridine, adenine, inosineも血漿において測定が可能と考えられた.
