西雅图地区出现多重抗药性HIV
http://www.baltimoregaylife.com/News/National/020907.htm
西雅图 - King郡, 华盛顿州在4位男同身上发现一种难治的爱滋病毒, 而专家怕它很可能会传向更多人.
目前并无证据现实此种病毒正在快速散播, 卫生安全局说, 但它的出现强调出Oregon市民对重新加强安全性校育的需要.
“外面有可能还有更多我们不知到的案例,” 卫生局HIV/AIDS 方案主任 Bob Wood 医生说. Dorothy Teeter, 卫生局暂时性局长, 表示当局已经在调查此案.
同一种基因的HIV病毒在15个月内在全4人身上发现. 4人都是脱氧麻黄碱服用者, 有过多位伴侣, 但没有和其它3人任何一人有过性关系.
“那时很不寻常的现象,” Peter Shalit医生, 瑞典医疗中心专门治疗HIV-AIDS病患和HIV-AIDS 研究的指导, 说. 其中一个可能性是这是一种多种药抗并比以前的抗药种更容易散布的新型HIV病毒. “决对是个可怕的前景,” 他对报社说.
12 月2004年被断定有多种药抗的变种HIV的那一位纽约男子也是有多名匿名的性伴侣, 脱氧麻黄碱服用历史, 并和其它男性有性关系, 根据CDC*的资料.
就全国来讲, 2~3百分比的HIV 病毒可能是对2, 3种的药有抗性, 专家说.
西雅图是国内在2003最先开设对多种药抗HIV病毒观察计划的城市之一, 报社说. 从2003年开始健保提供者被要求定时对HIV-阳性的病患进行抗药病毒的检验, 并整理报告结果.
Robert. D. Harrington医生, Harborview医疗中心HIV诊所所长, 说有多种药抗的病患治疗费用可多与普通HIV病患的$15000美金达两倍.

Seattle Area Sees Drug-Resistant HIV
SEATTLE – A hard-to-treat strain of the virus that causes AIDS has been discovered in four gay men in King County, Washington, and authorities fear it could spread to more.
There is no evidence that the strain of HIV is spreading quickly, but its appearance underscores the need for renewed emphasis on safe sex practices, health officials told The Oregonian.
"There may be more cases we don't know about," said Dr. Bob Wood, the agency's HIV/AIDS program director. Dorothy Teeter, interim director of the department, said an investigation is ongoing.
The same genetic strain of HIV was found over a 15-month period in all four men, methamphetamine users who each had multiple partners, but none is known to have had sex with any of other three, officials said.
"That's highly unusual," said Dr. Peter Shalit, who treats HIV-AIDS patients and directs HIV-AIDS research at Swedish Medical Center. One possibility is that there is a new strain of multi-drug-resistant HIV that is spread more easily than previous drug-resistant strains, "definitely a scary prospect," he told the paper.
One man in New York, diagnosed with HIV in December 2004, was found to have a multi-drug-resistant type of HIV and he too had multiple, anonymous sexual partners, a history of methamphetamine use and had sex with men, according to the CDC.
Nationally, 2 percent to 3 percent of the HIV strains that people are infected with may be resistant to two to three classes of drugs, officials said.
Seattle was among the first cities in the country to begin a surveillance program for multi-drug-resistant HIV in 2003, the paper reported. Since then, health care providers have been asked to test routinely for drug resistance in anyone who is HIV-positive and to report indications of multi-drug-resistant strains. |
