A prospective, randomized, double-blind study was designed to compare Clostridium difficile immune whey (CDIW) with metronidazole for treatment of laboratory-confirmed, recurrent, mild to moderate episodes of Clostridium difficile-associated diarrhoea (CDAD). CDIW was manufactured by immunization of cows in their gestation period with inactivated C. difficile vaccine. The resulting colostrum was processed, immunoglubulins were concentrated and the end-product containing high titres of C. difficile immunoglobulin was used as CDIW. 20 patients received metronidazole at a dosage of 400 mg t.i.d. and 18 patients CDIW 200 ml t.i.d. The study was interrupted early because of the bankruptcy of the sponsor. After 14 d of treatment, all 20 (100%) of 20 patients had responded to metronidazole therapy, compared with 16 (89%) of 18 who had received CDIW. 70 d after the beginning of treatment, sustained responses were observed in 11 (55%) of 20 patients receiving metronidazole and 10 (56%) of 18 patients treated with CDIW. In this preliminary study CDIW was as effective as metronidazole in the prevention of CDAD recurrences and it was well tolerated.
