Chickens Make Malaria Mosquitoes Fly the Coop

Posted 21 Jul 2016 by Drugs.com

THURSDAY, July 21, 2016 – Although a chicken may seem a strange choice for a bedfellow, sleeping with a poultry partner next to your bed could protect you from malaria, a new study suggests. Researchers found that one of the main mosquito species (Anopheles arabiensis) that transmits malaria in sub-Saharan Africa avoids chickens when looking for a meal of blood. The mosquitoes use their sense of smell to distinguish between chickens and animals they feed on. The discovery suggests that odors emitted by chickens and other animals mosquitoes don't like to feed on could help protect people from mosquito-borne diseases, the researchers said. The study was published July 20 in the Malaria Journal. "We were surprised to find that malaria mosquitoes are repelled by the odors emitted by chickens. This study shows for the first time that malaria mosquitoes actively avoid feeding on certain ... Read more

Malaria Vaccine Protection Short-Lived in Young Children

Posted 1 Jul 2016 by Drugs.com

THURSDAY, June 30, 2016 – The world's most promising malaria vaccine appears to offer short-lived protection, fading away within a matter of years, a new clinical trial reveals. Even worse, the vaccine – dubbed RTS,S/AS01 – might increase children's long-term risk of contracting malaria if they live in a region with heavy transmission of the mosquito-borne parasite, the researchers found. The vaccine can "lead to a situation where unvaccinated children have more natural immunity than vaccinated children, and therefore get less malaria," said senior researcher Philip Bejon. He's director of the Kenya Medical Research Institute-Wellcome Trust Program in Kilifi, Kenya. The results indicate that RTS,S/AS01 could have limited usefulness in the global fight to eradicate malaria, said malaria expert Dr. Christopher Plowe, a professor of medicine with the University of Maryland School of ...

Malaria Vaccine Shows Promise in Small Study

Posted 10 May 2016 by Drugs.com

TUESDAY, May 10, 2016 – An experimental malaria vaccine protects a majority of adults against the mosquito-borne virus for up to one year, according to the results of a small study. The findings also showed those who were vaccinated couldn't spread the virus to others. "These results are really important," researcher Kirsten Lyke, from the University of Maryland School of Medicine in Baltimore, said in a university news release. "Malaria has such a devastating effect on children, especially in Africa. This vaccine has the potential to help travelers, military personnel and children in malaria-endemic areas." Hundreds of millions of people are infected with malaria and more than 500,000 die from the virus each year, the researchers noted. Most fatal cases of malaria involve children under the age of 5, the study authors said. The first symptoms – which can include fever, headache, ... Read more

Zika Virus Was in Haiti Long Before Brazil Outbreak: Study

Posted 29 Apr 2016 by Drugs.com

FRIDAY, April 29, 2016 – New research suggests the Zika virus was circulating in Haiti months before Brazil's first cases were reported last spring. "We know that the virus was present in Haiti in December of 2014," said Dr. Glenn Morris, director of University of Florida's Emerging Pathogens Institute. "And, based on molecular studies, it may have been present in Haiti even before that date." What remains unclear is exactly why there was such a widespread outbreak in Brazil, the study authors said, and more research is needed to reveal why the same did not happen in Haiti. In Brazil, Zika infections have been linked to more than 5,000 cases of a birth defect known as microcephaly, in which babies are born with abnormally small heads and brains. To uncover Zika's presence in Haiti, the team of researchers analyzed three "mystery" infections reported in that country in 2014. The cases ... Read more

Life-Saving Health Care in Poor Nations Would Cost $5 Per Person: Study

Posted 10 Apr 2016 by Drugs.com

SUNDAY, April 10, 2016 – The cost of health care that could save the lives of millions of children and their mothers every year would be less than $5 per person, researchers report. The money would expand basic health services – such as birth control, nutritional supplements and medication to treat serious illnesses such as pneumonia and malaria – in 74 low- and middle-income countries. Those countries account for more than 95 percent of mother and child deaths each year, according to the study published April 9 in The Lancet. The researchers reported that, worldwide, in 2015 nearly 6 million children under age 5 died, as did more than 300,000 women from pregnancy-related causes. "Many of these deaths could be prevented if high-impact and affordable solutions reached the populations that needed them most," study leader Dr. Robert Black said in a John Hopkins University news release. ...

Combo Treatment Protects Pregnant Women, Fetuses From Malaria in Study

Posted 10 Mar 2016 by Drugs.com

WEDNESDAY, March 9, 2016 – A combination drug therapy widely used to treat malaria in adults also protects pregnant women and their fetuses from the disease, according to a new study. Malaria is a leading cause of premature birth, low birth weight and death among infants in Africa, the researchers said. Most Africans develop immunity to malaria by adulthood, but women lose some of this immunity during pregnancy and are given drugs to prevent infection. The recommended preventive drug is sulfadoxine-pyrimethamine (SP), but the mosquito-transmitted parasite that causes malaria is often resistant to it. Researchers assessed whether the combination therapy dihydroartemisinin-piperaquine (DP) – commonly used to treat malaria in adults – could prevent malaria in pregnant women. The study included 300 pregnant women in Uganda. Beginning in the 16th week of pregnancy, about one-third of the ... Read more

Preventable Ills Cause Nearly 8 Million Childhood Deaths Globally

Posted 25 Jan 2016 by Drugs.com

MONDAY, Jan. 25, 2016 – Most of the nearly 8 million deaths of children and teens around the world in 2013 were avoidable, a new report says. More than 6 million children younger than 5 lost their lives because of treatable conditions like malaria, diarrhea and respiratory tract infections, according to pediatric researchers who've analyzed results of the Global Burden of Disease Study 2013. "The vast majority of deaths in children and adolescents are preventable," said the authors from the Global Burden of Disease Pediatrics Collaboration. "Proven interventions exist to prevent diarrheal and respiratory diseases, neonatal conditions, iron deficiency anemia and road injuries, which result in some of the highest burdens of unnecessary death and disability among children and adolescents." For the study, the researchers from around the world used data from a variety of sources to target ... Read more

Pediatricians' Group Urges Action on Climate Change

Posted 26 Oct 2015 by Drugs.com

MONDAY, Oct. 26, 2015 – Dirtier air, heat stress, greater exposure to Lyme disease – these and other threats to children will increase because of climate change, a leading group of U.S. pediatricians warns. Doctors and policy makers must take steps to protect youngsters from the hazardous effects of climate change, the American Academy of Pediatrics said in a new policy statement. "Every child needs a safe and healthy environment and climate change is a rising public health threat to all children in this country and around the world," academy president Dr. Sandra Hassink said in a news release from the organization. The threats to children also include natural disasters, more infectious diseases and problems with food and water supplies, the academy said. "Pediatricians have a unique and powerful voice in this conversation due to their knowledge of child health and disease, and their ... Read more

Gains in Life Spans Seen Around the Globe

Posted 27 Aug 2015 by Drugs.com

THURSDAY, Aug. 27, 2015 – Average life expectancy among people worldwide has risen by more than six years since 1990, and healthy life expectancy has climbed by more than five years, a new report shows. The analysis of data from 188 countries found that life expectancy for both sexes increased from just over 65 years in 1990 to 71.5 years in 2013, while healthy life expectancy rose from almost 57 years to slightly more than 62 years. The findings regarding healthy life expectancy versus total life expectancy mean that people are living more years with illness and disability, according to the authors of the study published Aug. 27 in The Lancet. "The world has made great progress in health, but now the challenge is to invest in finding more effective ways of preventing or treating the major causes of illness and disability," study author Theo Vos, a professor at the Institute for Health ...

Ebola Linked to Rise in Malaria Deaths in Guinea

Posted 24 Jun 2015 by Drugs.com

WEDNESDAY, June 24, 2015 – The Ebola epidemic in West Africa appears to have led to an increase in malaria deaths last year, a new study finds. Research in Guinea, one of the countries hardest hit by the Ebola epidemic, indicates an extra 74,000 cases of malaria went untreated in 2014, compared to previous years. As a result, deaths associated with malaria (a mosquito-borne disease) also rose and will likely exceed Ebola deaths in Guinea, researchers reported June 23 in The Lancet Infectious Diseases. "One problem is that the early symptoms of malaria [fever, headache and body aches] mimic those of Ebola virus disease," said study author Dr. Mateusz Plucinski, from the U.S. Centers for Disease Control and Prevention. "Malaria is one of the main causes of fever and health facilities visits in Guinea, but our data suggest that since the start of the Ebola epidemic, people with fevers ... Read more

Ebola Outbreak May Have Led to Almost 11,000 Additional Malaria Deaths: Study

Posted 23 Apr 2015 by Drugs.com

THURSDAY, April 23, 2015 – Nearly 11,000 extra deaths due to malaria may have occurred in 2014 because of disruptions in health care services caused by the Ebola outbreak in West Africa, a new study suggests. Another 3,900 extra malaria deaths may have been caused by the interruption of delivery of insecticide-treated sleeping nets, the British researchers said. The study appears online April 23 in The Lancet Infectious Diseases. "The ongoing Ebola epidemic in parts of West Africa largely overwhelmed already fragile health care systems in 2014, making adequate care for malaria impossible and threatening to jeopardize progress made in malaria control and elimination over the past decade," study author Patrick Walker, of the MRC Centre for Outbreak Analysis and Modelling at Imperial College London, said in a journal news release. The findings suggest that the number of malaria deaths ... Read more

Malaria Vaccine Shows Promise in Shielding African Children

Posted 23 Apr 2015 by Drugs.com

THURSDAY, April 23, 2015 – According to the World Health Organization, about 584,000 people, mostly in Africa, die from mosquito-borne malaria each year. Most of those victims are children, but the success of a new malaria vaccine in late-stage trials could offer real hope against the disease, experts say. There is currently no vaccine for malaria, and the new vaccine, called RTS,S/AS01, was developed for use in sub-Saharan Africa, where malaria kills about 1,300 children every day. The phase 3 trial of the vaccine included more than 15,400 newborns (ages 6 to 12 weeks at first vaccination) and children (5 to 17 months at first vaccination) at 11 sites in seven sub-Saharan African countries. A team led by Brian Greenwood, of the London School of Hygiene and Tropical Medicine, reported that the vaccine protected the children more than the newborns, but protection weakened over time in ...

Malaria Growing Resistant to Drugs Used to Fight It

Posted 30 Jul 2014 by Drugs.com

WEDNESDAY, July 30, 2014 – The parasite that causes malaria is growing increasingly resistant to the drugs commonly used to fight it, according to new surveillance reports. But several new drugs are in development, and at least one in early clinical trials may offer new hope against this global killer. "Although there has been considerable progress in malaria control in the past decade, the battle against malaria is far from won, and there is still much more to do," said Dr. Brian Greenwood, professor of tropical medicine at London School of Hygiene and Tropical Medicine, who wrote a commentary accompanying the new research. Especially worrisome is the growing power of malaria parasites to survive the drugs that are designed to kill them, Greenwood said. One study reported widespread resistance to the drug artemisinin across mainland Southeast Asia. A second study found resistance to a ... Read more

Researchers Explore New Target for Malaria Vaccine

Posted 25 May 2014 by Drugs.com

THURSDAY, May 22, 2014 – Scientists have developed a new vaccine for malaria using protective immune system cells from children who appear to be naturally resistant to the deadly infectious disease. Initial tests of the vaccine in mice looked promising, according to a new study. Certain children are naturally resistant to the mosquito-borne infectious disease. And, it was recently discovered that these children harbor certain protective immune system cells (antibodies). These antibodies are programmed to block the malaria parasite from getting out of red blood cells, where they can multiply and cause more serious disease. The researchers created a vaccine with these antibodies. And, when given to mice, the vaccine offered some protection against malaria. When the animals were given a malaria strain that is universally fatal to mice, the vaccinated rodents developed lower levels of the ... Read more

First Effective Malaria Vaccine May Be Near, Experts Say

Posted 8 Oct 2013 by Drugs.com

TUESDAY, Oct. 8 – Promising results from a large-scale clinical trial mean that the world's first malaria vaccine may be on the market by 2015 and could potentially save hundreds of thousands of lives a year. The phase III clinical trial of more than 15,000 infants and young children in Africa found that the vaccine – called RTS,S – continued to protect the youngsters from malaria for up to 18 months after vaccination. The ongoing trial of the RTS,S vaccine is being conducted by 11 research centers in seven African countries, together with the PATH Malaria Vaccine Initiative and drug maker GlaxoSmithKline. "It appears that the RTS,S candidate vaccine has the potential to have a significant public health impact," Halidou Tinto, lead investigator from the Nanoro, Burkina Faso trial site in West Africa, said in a PATH news release.
