Due to mass tourism and the exodus of refugees from Africa and Asia, typhoid fever, common in the tropics, has reappeared in the more temperate climates. The clinical signs of prolonged fever, headache, general malaise, anorexia and abdominal pain are not specific enough to allow diagnosis and only a blood culture will prove the presence of the disease. Unless there is resistance, which is in fact rare in Southeast Asia, chloramphenicol, an effective, well tolerated and cheap antibiotic, remains the treatment of choice for typhoid. In the search for an alternative treatment a cephalosporin, ceftriaxone (Rocephin) seems promising. It has a low MIC of 0.05 micrograms/ml for S. typhi and a high level of biliary excretion which destroys S. typhi in the bile and thus prevents relapse. In Southeast Asia three consecutive studies, of which two were randomised and comparative with chloramphenicol given for 14 days, showed that treatment for two or three days, 3 or 4 g per day of ceftriaxone was as effective as chloramphenicol and was not followed by relapse. In 46 adults there was one failure with ceftriaxone (in an immunocompromised patient) and none in the 30 patients treated with chloramphenicol, three of which, however, relapsed in the 15 days after completion of treatment. Defervescence was a little more rapid with chloramphenicol (six to seven days) than with ceftriaxone (seven to ten days) even though blood, urine and stool cultures were all negative from the third or fourth day of treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
由于大众旅游以及非洲和亚洲难民的涌入,伤寒热这种在热带地区常见的疾病,在气候较为温和的地区再度出现。持续发热、头痛、全身不适、食欲不振和腹痛等临床症状特异性不足,无法据此诊断,只有血培养才能证实疾病的存在。除非存在耐药性(实际上在东南亚很少见),氯霉素作为一种有效、耐受性良好且廉价的抗生素,仍然是伤寒治疗的首选。在寻找替代治疗方法的过程中,一种头孢菌素——头孢曲松(罗氏芬)似乎很有前景。它对伤寒杆菌的最低抑菌浓度为0.05微克/毫升,且胆汁排泄水平高,能在胆汁中杀灭伤寒杆菌,从而预防复发。在东南亚进行的三项连续研究中,其中两项为随机研究且与使用14天氯霉素的情况进行对比,结果显示,每天3或4克头孢曲松治疗两到三天与氯霉素效果相同,且不会出现复发情况。在46名成年人中,使用头孢曲松有1例治疗失败(该患者免疫功能低下),而使用氯霉素治疗的30名患者无一例失败,不过其中有3例在治疗结束后的15天内复发。尽管从治疗的第三天或第四天起血、尿和粪便培养结果均为阴性,但氯霉素的退热速度(六到七天)比头孢曲松(七到十天)略快一些。(摘要截选至250字)
