Revisions have been made to the latest version of guidelines for diagnosis and treatment of HIV/AIDS, with the Centers for Disease Control (CDC) recommending earlier treatment.
People with HIV-negative sexual partners are advised to begin treatment regardless of their cluster of differentiation 4 (CD4) count.
The fourth version of the Ministry of Health and Welfare guidelines recommends an earlier starting point for HIV treatment for HIV-positive people at a CD4 T-cell count of 500 or less, or 500 T-cells or less per cubic millimeter of blood, according to the Taiwan AIDS Society.
Studies have shown that starting the antiretroviral therapy at a CD4 count of between 350 and 500 reduces the incidence of opportunistic infections and lowers the death rate in HIV-positive patients, the society said, adding that the WHO raised the treatment bar in June from a CD4 count of 350 to 500, and 90 percent of the countries in the world have since adopted the new guideline.
Another revision to the guidelines recommends that HIV treatment be provided to HIV-positive people who might transmit the virus to their sexual partners, regardless of CD4 count.
According to the result of a clinical trial — known as HPTN 052 — where one partner is HIV-positive and the other is not (serodiscordant), the antiretroviral treatment on HIV-positive people can reduce the risk of transmitting the virus to their HIV-negative sexual partners by 96 percent.
The US Department of Health and Human Services guidelines last year recommended all serodiscordant couples to start treatment regardless of CD4 T-cell counts, followed by the WHO this year.
Centers for Disease Control Director-General Chang Feng-yee (張峰義) said that the cost of HIV treatment, which has exceeded NT$2.6 billion (US$87 million) a year in recent years, is shouldered by the CDC.
Following the guidelines recommended by the WHO can lower the risk of opportunistic infections and prolong the lives of HIV-positive patients, but the price is an upsurge in the cost of medicine, Chang said.
Chang added that preliminary thoughts on how to contain the cost is to have those who often stop the treatment to discontinue taking the drugs, for now, to avoid potential drug-resistance.
Taiwanese scientists have engineered plants that can capture about 50 percent more carbon dioxide and produce more than twice as many seeds as unmodified plants, a breakthrough they hope could one day help mitigate global warming and grow more food staples such as rice. If applied to major food crops, the new system could cut carbon emissions and raise yields “without additional equipment or labor costs,” Academia Sinica researcher and lead author the study Lu Kuan-jen (呂冠箴) said. Academia Sinica president James Liao (廖俊智) said that as humans emit 9.6 billion tonnes of carbon dioxide compared with the 220 billion tonnes absorbed
The Taipei Mass Rapid Transit (MRT) Wanda-Zhonghe Line is 81.7 percent complete, with public opening targeted for the end of 2027, New Taipei City Mayor Hou You-yi (侯友宜) said today. Surrounding roads are to be open to the public by the end of next year, Hou said during an inspection of construction progress. The 9.5km line, featuring nine underground stations and one depot, is expected to connect Chiang Kai-shek Memorial Hall Station to Chukuang Station in New Taipei City’s Jhonghe District (中和). All 18 tunnels for the line are complete, while the main structures of the stations and depot are mostly finished, he
Taipei is to implement widespread road closures around Taipei 101 on Friday to make way for large crowds during the Double Ten National Day celebration, the Taipei Department of Transportation said. A four-minute fireworks display is to be launched from the skyscraper, along with a performance by 500 drones flying in formation above the nearby Nanshan A21 site, starting at 10pm. Vehicle restrictions would occur in phases, they said. From 5pm to 9pm, inner lanes of Songshou Road between Taipei City Hall and Taipei 101 are to be closed, with only the outer lanes remaining open. Between 9pm and 9:40pm, the section is
China’s plan to deploy a new hypersonic ballistic missile at a Chinese People’s Liberation Army Rocket Force (PLARF) base near Taiwan likely targets US airbases and ships in the western Pacific, but it would also present new threats to Taiwan, defense experts said. The New York Times — citing a US Department of Defense report from last year on China’s military power — on Monday reported in an article titled “The missiles threatening Taiwan” that China has stockpiled 3,500 missiles, 1.5 times more than four years earlier. Although it is unclear how many of those missiles were targeting Taiwan, the newspaper reported
