Recent reports about HIV patients being “functionally cured” after early medical intervention should not be a reason for patients to make a unilateral decision to stop treatment, the Centers for Disease Control (CDC) said yesterday, underscoring that the cases reported are extremely rare and thus not applicable to all patients.
Other than a report of a baby born in Mississippi, US, having reportedly been cured of an infection with the virus that causes AIDS, French researchers announced last week that 14 patients who have received antiretroviral treatment within 10 weeks of being infected with HIV have after seven-and-a-half years showed no signs of the virus returning, leading to doctors calling them “functionally cured.”
The CDC yesterday said that although the virus in those cases could be controlled at low levels without the ability to replicate in the blood, they are nonstandard cases.
Luo I-chun (羅一鈞), a physician specializing in disease prevention at the centers, said that the patients reportedly received treatment shortly after becoming infected, a practice that is not always possible for most people with HIV, because they usually do not find out about the infection until the virus has already infiltrated the body.
Luo added that “the 14 functionally cured people were identified out of a total of 70 patients whose treatment had been interrupted,” while the rest of the 70 patients relapsed and had the virus returning to pre-treatment levels.
CDC statistics showed that as of the end of last year, Taiwan had 13,323 patients with HIV taking antiretroviral drugs and 20 percent of them have not regularly revisited doctors for treatment.
An analysis has found that 95 percent of patients who have been taking drugs regularly have a viral load so low that the virus is no longer detectable, which shows that only regular treatment can control the viral load and reduce the risk of patients developing other life-threatening infections, the CDC said.
In most of the patients, the viral load in their blood increased after they stopped taking antiretroviral drugs. An interruption of treatment might also result in drug resistance and eventually in therapy failure, the CDC said.
It advised all patients infected with HIV to take antiretroviral drugs on a regular basis to prevent their immune systems being compromised and their developing other infections, which can lead to an early death.
A Taipei veterinarian is urging pet owners to avoid using insecticides around their homes, as their ingredients can be toxic to pets. Commercial-grade insecticides contain pyrethroids — organic compounds similar to natural pyrethrins, pesticides produced by flowers such as chrysanthemums — in quantities that are harmless to humans, but potentially fatal to cats and dogs, Asian Veterinary Specialist Referral Center veterinarian Chua Man-ling (蔡曼琳) said. Even in small quantities, pyrethroids are hazardous to cats, as they lack the metabolic enzymes needed to process them, Chua said. Cockroach sprays and ant traps are especially dangerous to pets as they contain boric acid, she
DOING ENOUGH? The HPA budgets NT$1.3 billion to prevent the health hazards of tobacco, but has no separate budget to fight teen drinking, a doctor said The government should step up alcohol education and prevention efforts, and allocate more of the budget to it, doctors said on Friday, citing the high consumption of alcohol among Taiwanese adolescents. One out of four 12-to-17-year-olds has consumed alcohol, said Yen Tsung-hai (顏宗海), director of Linkou Chang Gung Memorial Hospital’s Department of Clinical Toxicology. The Health Promotion Administration (HPA) budgets NT$1.3 billion (US$43.9 million) annually to prevent the health hazards of tobacco, but it has not allocated a separate budget for preventing teenage drinking or excessive alcohol use, Yen said. “There is no so-called ‘safe drinking level’ for minors,” because any amount consumed
DREAMING OF TRAVEL: About 7,000 people applied for the experience, with about 60 chosen for the first flight yesterday, which includes boarding an airplane Starved of the travel experience during COVID-19?

The Fancy Frontier manga and anime expo held in Taipei over the weekend has sparked controversy, after a participant allegedly contravened the Act on Offenses Against Sexual Morality (妨害風化罪) by publicly exposing her private parts during a photo shoot. The two-day event opened at the Expo Dome at the Taipei Expo Park on Saturday, attracting numerous comic and anime creators, cosplayers, photographers and fans. Allegedly, a female cosplayer who was not wearing any underwear lifted up her skirt and revealed her private parts at an outdoor photography area near the venue. Event organizers said yesterday that to prevent indecent exposure, they have since
