Malaria caused by Plasmodium parasites kills
approximately 1.3 million people and causes disease in 300-500 million
people annually throughout the world. The parasite is spread to people by
the female Anopheles
mosquito, which feeds on human blood. Malaria kills over 5,000 people
a day, 90 percent of whom are children under the age of five and living in
Africa. This infection is present in 107 countries and affects 10 percent of the
world's population, mostly in sub-Saharan Africa and the Indian
subcontinent. Malaria may have jumped to humans from chimpanzees much as
AIDS did.
Human infection with Plasmodium species leading to malaria probably began
very early in the history of humankind and has persistently inflicted
disease among human populations. Malaria is currently considered the
world's most important infection from a parasite. The global impact of
malaria is incalculable and appears to be worsening over the past decades.
It is believed that at no time in the history of the human race malaria
has been absent. This disease, which is caused by
protozoa of the genus
Plasmodium, in all likelihood has been responsible for the death of about
half of all people who ever lived.
Malaria herb, natural
treatment with plant extracts
Artemisinin -The effectiveness of an anti-malarial herbal medicine could be
damaged by overplanting of the Chinese shrub from which it is derived. The
artemisia annua (sweet wormwood) shrub must be more carefully farmed to
meet a growing global demand and to keep fakes off the market. Chinese
herbalists have used leaves from the shrub to treat malaria for centuries.
It is now widely regarded as the best drug to treat the disease. Not all
shrubs yield enough for the malaria-fighting compound artemisinin to be
effective against malaria. Resistance to conventional anti-malarial drugs
such as chloroquine or amodiaquine have triggered great demand for
artemisinin therapy which the WHO has recommended since 2001 in
combination with other drugs as a malaria cure. Counterfeit and
sub-standard malaria drugs have become a problem in parts of Africa and
Asia.
Clove herb may offer
benefit.
Tongkat ali herb has compounds that have been tested.
Xanthones from mangosteen plant may have some potential.
Malaria and
travel
Although most of this burden of malaria disease is carried by
developing tropical countries, cases of imported malaria acquired by
international travel are increasingly reported. These numbers are growing
because of increased travel to malaria -endemic areas and also due to
increased risk of transmission in these areas. Travel has contributed to
the global spread of malaria during the history of humankind. Travelers
visiting malaria risk areas should use both personal protective measures
and prevention by taking anti malaria drugs. It is possible that some
countries may begin spraying again with
ddt.
Testing for Malaria resistant
to chloroquine
If travelers become sick after returning from areas in which chloroquine-resistant
malaria is endemic, they need to be quickly checked for the disease. A new
assay can do just that. Improved diagnostics are urgently needed to help
control the global spread of drug-resistant malaria. Currently, the
detection of malaria depends upon microscopic techniques from the 1800s. Imported drug-resistant malaria is a growing
problem in industrialized countries. For the elderly or those who develop severe
malaria, the mortality rate can exceed 20 percent. Researchers have now
developed a real-time assay based on detecting
DNA from the
malaria parasite known as Plasmodium falciparum, along with the genetic
variations that render it resistant to the standard drug, chloroquine. When the
researchers used the test to screen 200 returning travelers with suspected
malaria, they found that 77 patients had chloroquine-resistant P. falciparum
infection and 48 had a chloroquine-susceptible strain. Another 35 had other
types of malarial infection, while the remaining 40 patients had other causes of
fever. Clinical Infectious Diseases, March 1, 2006.
Symptoms and Signs of Malaria
Fever, headache, fatigue, malaise, and musculoskeletal pain are the
most frequent clinical features. In endemic areas, the presence
of liver enlargement, thrombocytopenia and
anemia is clearly associated
with malaria, particularly in children. Following single exposure to
Plasmodium falciparum infection, the patient will either die in the acute
attack or survive with the development of some immunity. Elderly
individuals are prone to a more severe course of disease. The non-fatal P.
vivax and P. ovale cause similar initial illnesses, with bouts of fever
relapsing periodically, but irregularly over a period of up to 5 years.
Kidney involvement of a moderate degree is more common in mild falciparum
malaria than initially suspected. The liver is also afflicted in mild
disease, but organ damage is limited and fully reversible after
parasitological cure. Co-infection can aggravate malaria. There is a
growing body of evidence that there is significant interaction in terms of
mutual aggravation of the course of disease between HIV and malaria,
particularly in pregnant women.
Malaria Treatment
Widespread resistance to the best and least expensive antimalarials,
chloroquine and S/P (i.e., a combination of sulfadoxine and pyrimethamine),
combined with an increasing tolerance to insecticides in the mosquito
vector, threaten a global malaria tragedy unless new countermeasures are
developed. For malaria therapy, the great panacea would be the development
of a long-lasting vaccine, but until this becomes a reality, people living
in and traveling to endemic regions must rely on a limited number of more
expensive drugs.
A cheap and widely available malaria drug is an effective treatment
for pregnant women. Amodiaquine is an older malaria treatment that has
been found safe during pregnancy. Researchers at the London School of
Hygiene and Tropical Medicine treated 900 pregnant women in Ghana with the
malaria drug and found it eliminated the malaria parasite without causing
any serious side effects. "Previous studies had already found amodiaquine
alone or in combination with sulphadoxine-pyrimethamine (SP) to be an
effective treatment of malaria in children in west Africa, but our
research confirms that this is also true for pregnant women," said
Professor Brian Greenwood who reported the findings in The Lancet medical
journal.
Risk of Serious and Life-Threatening hematologic reactions, including thrombocytopenia, hemolytic uremic syndrome/thrombotic thrombocytopenic purpura with Qualaquin (quinine sulfate) Capsules, 324 mg. Dear Healthcare Provider: AR Scientific, Inc. would like to inform you of important safety information regarding the use of Qualaquin (quinine sulfate) capsules, 324 mg. Qualaquin Capsules are approved only for the treatment of uncomplicated Plasmodium falciparum malaria. Qualaquin capsules are not approved for treatment or prevention of nocturnal leg cramps.
Artemisinin medication
The World Health Organisation warned in September 2009 that the parasite
which causes malaria is increasingly resistant to artemisinin, the best
drug around, and failure to contain this trend would bring serious
consequences. "This (Asia Pacific) region has traditionally been the
focus of resistance to antimalarial drugs and now we have artemisinin
resistance primarily on the Thai-Cambodian border," said John Ehrenberg,
WHO regional adviser on malaria and other vectorborne and parasitic
diseases.
Mefloquine and Malaria
Multiple-drug-resistant malaria is widespread, and in South-East
Asia resistance is high against nearly all single therapy antimalarial
drugs. Here, and in other areas with low malaria transmission, the
combination of artesunate and mefloquine may provide an effective
alternative. Artesunate plus mefloquine performs better than mefloquine
alone for treating uncomplicated falciparum malaria in areas with low
malaria transmission. A total dose of 25 mg/kg mefloquine and at least 10
mg artesunate leads to higher cure rates.
Mefloquine malaria drug not be
used if you have depression
Many people are not suitable candidates for the anti malaria drug
mefloquine, also known by the trade name Lariam. Those unsuitable for
mefloquine use are people with major depressive disorder and Parkinson's
disease. Anticonvulsants are also anotherreason not to use mefloquine.
Chloroquine and Malaria
The inexpensive drug chloroquine may again be effective in treating
malaria because years of disuse have boosted its potency against the often
fatal mosquito-borne disease. Chloroquine had been the mainstay of malaria
therapy until the disease developed a resistance to it and health
officials stopped using it widely more than a decade ago. Now a study,
published in this week's New England Journal of Medicine shows the malaria
drug is newly potent again, perhaps because the strains of the disease
that were once immune to it have more trouble surviving. Researchers who
tested children found that the drug packed a new punch, working 99 percent
of the time. A replacement treatment, sulfadoxine and pyrimethamine, was
effective in only 21 percent of the cases. Chloroquine is simple to
administer, requires only a few doses, has few side effects and costs
about 10 cents per treatment, far less than any other therapy.
Drugs used for malaria may
help with lupus
Dr. Bernardo A. Pons-Estel, from Hospital Provincial de Rosario,
Argentina recommends that doctors give the drugs to all patients with
lupus. Doctors first
realized decades ago that antimalarial drugs such as hydroxychloroquine
could be used to treat the joint pain often seen in lupus, according to
the Lupus Foundation of America. Since then, research has suggested that
antimalarial therapy can help prevent flare-ups of lupus and reduce
overall damage from the disease, Dr. Bernardo A. Pons-Estel, and his
team studied nearly 1,500 patients with lupus from 9 countries. They
followed them for an average of about four and a half years. The study
was not "blinded" - in other words, subjects, and their doctors, knew
what treatments they were getting. About 12 percent of the patients who
did not use the drugs died during the follow-up period, compared to
about 4 percent of those who did. The difference was even higher for
patients who used the drugs for more than two years. Arthritis and
Rheumatism, online January 7, 2010.
Fake Malaria Drugs
Fake China-made malaria drugs, which have flooded parts of Asia and killed many people in recent years, are beginning to show up in Africa where the dummy tablets are expected to take far more lives. Malaria kills 1.3 million to 3 million people a year, or one every 30 seconds, and 90 percent of them occur in Africa. Since 2001, the World Health Organization has recommended therapies containing artesunate, a compound extracted from a Chinese herb. But fake artesunate has flooded places such as Cambodia, Laos Vietnam and Myanmar in recent years, resulting in deaths. There are no estimates because many malaria victims typically reside in remote areas, but experts believe there have been many.
Malaria and HIV
Combining anti-AIDS drugs, an antibiotic and bed nets treated with
insecticide could cut the rate of malaria infections in people infected
with HIV by up to 95 percent. Malaria and HIV are leading infections in
sub-Saharan Africa. In adults and children with HIV, malaria is more
common and can be more severe.
Malaria in India - June 2006 - A new strain of malaria has killed 55 people and infected more than 18,000 others in India's eastern state of West Bengal since January, 2006. In the famous tea district of Darjeeling, almost 2,400 people have been infected with malaria since January, compared with just 700 in the same period last year. Officials at the School of Tropical Medicine in Kolkata say a new strain of Plasmodium falciparum, the deadliest form of the malaria, is the likely cause of the infections. The new strain has been tracked to Myanmar, has mutated and has become drug resistant.
Malaria in Jamaica - December 2006 - Jamaican health authorities are battling an outbreak of malaria that has infected 15 people in the Kingston area but has so far not spread to other parts of the Caribbean island. Jamaica has not recorded a case of the mosquito-borne illness in 50 years, said Dr. Marion Ducasse, the health ministry's senior medical officer. The health ministry announced late on Monday that it had confirmed 15 cases of malaria, 6 of them among children and all of them in the capital and the neighboring central parish of St. Catherine.
Questions
Q. Does tongkat ali
help with malaria treatment? What about
LJ100?
A. Tongkat ali has shown some benefit in the test tube
in damaging the malaria bug, but adequate human studies are lacking.
Q. I wonder if the malaria my husband picked up
while in Japan could be related to his non-Hodgkin's Lymphoma. I read on a
web site the paragraph titled 'Non Hodgkin's lymphoma cause' that certain
viruses contribute to certain lymphoma subtypes in Africa and Japan. do
you have any further info about the viruses in Japan that would cause the
lymphoma and if it were possible to tell whether or not my husbands was
that type.
A. Infection with a parasite from the genus Plasmodium causes
malaria. Malaria is not caused by a virus.
My male friend took Lariam, mefloquine pills when we traveled to Africa, and I think it made him short tempered and almost crazy.
I think Thiamine, B1 vitamin in high doses will
prevent mosquito bites, that was my experience on the Zambezi river in
Zimbabwe. It has to be a high dose of vitamin B1, 100 mg dosage.
