Abstract
Description
(実施例1)
抗生物質で治療を受けた、長期再発性の尿感染症を有する48歳の女性が、慢性の下痢を発症した。検便を数回実施した後、便中に毒素産生性のクロストリジウム・ディフィシレが検出された。これは、非伝染性株であったが、それにもかかわらず慢性の下痢を引き起こし、その下痢は1日当たり10〜15回生じ、時に失禁の原因となった。
指を切り、その後サンフランシスコ病院の救急処置室内で縫合処置を受けた、ペニシリンに対してアレルギー性の9歳の男性に、予防的「クリンダマイシン」が投与された。クリンダマイシン投与終了後3〜4週間経過して、同患者は下痢を発症した。この下痢は、痙攣、急迫、倦怠感、及び約2〜3kgの進行性の体重減少を伴った。同患者は、C.ディフィシルの伝染性株を有すると診断され、メトロニダゾールが投与された。同患者は吐気を発現し、次にバンコマイシンカプセル250mgがtdsで投与された。同患者の下痢は、メトロニダゾール、またバンコマイシンのいずれによっても非常に効果的に阻止された。投薬停止後2〜4週間内に下痢が再発し、1日当たり最大8回又は12回の下痢便を伴った。その後18ヶ月にわたり、非常に多くの下痢の再発が認められ、その都度バンコマイシンで抑えられた。バンコマイシンの用量を低減する非常に多くのプロトコールが試みられたが、同患者は継続して下痢を有した。
