목적 : 항암화학요법 중 호중구감소증을 동반한 발열이 발생하는 암환자들을 치료하기 위한 다양한 항균제와 여러 가지 방법들이 시도되고 있는 가운데, 합병증과 사망률의 발생가능성이 적은 저위험군 환자들을 대상으로 초기 72시간동안 정주 항균제를 투여한 이후 경구 항균제로 전환하는 요법의 유용성과 안정성을 평가해보고자 본 연구를 시행하였다. 방법 : 1998년 2월부터 1999년 9월까지 본원에서 항암화학요법 중 호중구감소증과 발열이 발생한 환자들 가운데 기저 암질환이 고형암이거나 림프종이고, 입원당시 패혈증의 증후가 없으며 입원 72시간이내에 해열되고 백혈구수치가 증가 추세인 환자들을 대상으로 하여 72시간 동안 정주 항균제를 투여한 이후 경우 ciprofloxacin 750㎎을 하루 2회씩 투여하여 총 4일간 투여하였다. 모든 환자들은 열이 떨어지고 호중구감소증이 회복될 때까지 입원하도록 하였다. 결과 : 총 38명 환자의 40예가 등록이 되었고, 환자들의 기저암 질환은 고형함이 72.5%, 림프종이 27.5%였다. 입원당시 평균 호중구치수는 156/㎕였고, 호중구수치가 100/㎕미만인 경우는 65%였으며, 호중구감소증이 지속된 기간의 평균은 2.4일이었다. 40예 중 39예가 항균제의 변형이나 추가 없이 호중구감소증과 발열로부터 회복이 되어 97.5%의 성공율(95% 신뢰구간: 86.8-99.9%)을 보였다. 부작용으로 피부발진이 있었던 경우가 한 예 있었는데, 증상이 경하여 경구 항균제를 지속할 수 있었다. 심와부의 동통으로 복용을 지속할 수 없어서 대상에서 제외된 예가 또 한 예 있었다. 결론 : 항암요법 중 호중구감소증과 발열을 동반한 환자들 가운데 저위험군 환자들에서 항균제 72시간정주 이후 경구 항균제로의 전환요법은 효과적이고도 안전한 치료방법이라고 할 수 있다. Background : Oral antibiotic therapy following empirical intravenous antibiotics may be effective and safe for febrile neutropenic patients with lowrisk for complications. Methods : We conducted a prospective clinical trial of oral antibiotic therapy in the patients with neutropenia and fever during chemotherapy for cancer. Underlying malignancies were solid tumor or lymphoma with short duration of neurtropenia and the patients had no evidence of clinically or microbiologically documented infections. Oral ciprofloxacin was given to the patients who lacked signs of sepsis on admission, had a rising tendency of neutrophil count (ANC >100 /㎕ ) at 72 hours, and were afebrile at 72 hours. All patients were hospitalized until neutropenia and fever resolved. Results : A total of 40 episodes of 38 patients were enrolled from February 1998 to September 1999. The mean neutrophil counts on admission were 156/㎕ and the mean duration of neutropenia was 2.4 days. The episodes which had neutrophil count below 100 /㎕ were 26 (65%). Treatment was successful in 39 of 40 episodes (97.5% : 95 % confidence interval, 86.8% to 99.9%). Adverse reactions of oral ciprofloxacin were skin rash and epigastric soreness in two cases, respectively. There were no deaths during the study. Conclusions : For low-risk febrile patients with neutropenia during cancer chemotherapy, switch therapy to oral ciprofloxacin at 72 hours following intravenous broad-spectrum antibiotics is effective and safe,

In this study the antimicrobial spectrum and sensitivity of a liquid formulation of enrofloxacin against the major six pathogenic bacteria isolated from the diseased poultry in Korea were evaluated in comparison with ciprfloxacin (CFX), gentamicin (GM) and penicillin (PC). A liquid form of enrofloxacin, a test material and ciprofloxacin showed at least 83% antibacterial activity against all of six test pathogenic microorganisms at the fixed concentration of 10 ㎍/㎖. Gentamicin and penicillin revealed much lower antibacterial activity at the same condition. We evaluated the liquid form of enrofloxacin as having widespread antibacterial spectrum against poultry infections. The liquid form of enrofloxacin showed potent antibacterial activity, with the MIC range being 0.12∼2 ㎍/㎖ against Gram positives, 0.06∼2 ㎍/㎖ against Gram negatives and 0.5∼2 ㎍/㎖ against Mycoplasma spp. These values were equivalent to or somewhat higher than those of ciprofloxacin, but much lower than those of gentamicn and penicillin. This new liquid form of enrofloxacin would find its way in application of mixing with drinking water for the prevention and treatment of diverse infections in chickens.

We evaluated the efficacy of the liquid form of enrofloxacin against poultry respiratory and digestive infections, the major problems in the poultry industry, from diverse diagnosis viewpoints. Results obtained through this study were as follows: 1. The liquid form of enrofloxacin showed good acceptability to poultry owing to no abhorrence to the drug by chickens, which indicated its suitability for mixing in drinking water. 2. The application of the enrofloxacin formulation improved the productivity of the chicken farm to a great extent by lowering the death toll of chicken raised in the farm. 3. The use of the drug shortened the days to the market, and increased the body weight at the time of marketing. 4. Preventive and therapeutic effects of the liquid enrofloxacin were observed higher than ampicillin, a major antibiotic used in poultry farming. From above results, the liquid form of enrofloxacin would find its use for the prevention and treatment of digestive and respiratory infections, let alone the growth promotion and feed efficiency, especially in the chicken farming practice.
