Which of the following drugs is used to treat clinical malaria?

There are now few places in the world where chloroquine can be relied upon for falciparum malaria, and SP resistance is spreading rapidly—so recent information on drug susceptibility is required if these drugs are used. Amodiaquine is more effective than chloroquine against chloroquine-resistant P.

Which drug is used in treatment of malaria Mcq?

What is the best treatment for malaria?

The preferred antimalarial for interim oral treatment is artemether-lumefantrine (Coartem™) because of its fast onset of action. Other oral options include atovaquone-proguanil (Malarone™), quinine, and mefloquine.

What is malaria treatment and prevention?

Although it kills nearly one million people every year, malaria is preventable and curable. Some of the main methods of prevention are: Insecticide-treated bed nets. Most malaria-carrying mosquitoes bite at night, so insecticide-treated mosquito nets can be a life-saving barrier.

Which drug is used for malaria chemoprophylaxis and treatment?

Doxycycline, a synthetically derived tetracycline, is a partially efficacious causal prophylactic (liver stage of Plasmodium) drug and a slow acting blood schizontocidal agent highly effective for the prevention of malaria.

What is Act for malaria?

ACT is a combination of two or more drugs that work against the malaria parasite in different ways. This is usually the preferred treatment for chloroquine-resistant malaria. Examples include artemether-lumefantrine (Coartem) and artesunate-mefloquine. Other common antimalarial drugs include:

How to diagnose malaria?

To diagnose malaria, your doctor will likely review your medical history and recent travel, conduct a physical exam, and order blood tests. Blood tests can indicate: The presence of the parasite in the blood, to confirm that you have malaria. If your infection is caused by a parasite resistant to certain drugs.

What is the best treatment for parasites?

Chloroquine phosphate. Chloroquine is the preferred treatment for any parasite that is sensitive to the drug. But in many parts of the world, parasites are resistant to chloroquine, and the drug is no longer an effective treatment.

What is the best treatment for malaria?

After the initial course of IV artesunate is completed, if parasite density is ≤ 1% (assessed on a blood smear collected 4 hours after the last dose of IV artesunate) and patient can tolerate oral treatment, a full treatment course with a follow-on regimen must be administered. Artemether-lumefantrine (Coartem™) is the preferred follow-on treatment but adequate alternatives are atovaquone-proguanil (Malarone™), quinine plus doxycycline or clindamycin, or mefloquine. Because of a risk of severe neuropsychiatric adverse events at treatment doses, mefloquine should only be used if other options are not available. If the patient received oral treatment prior to receiving IV artesunate, the same medication can be used as follow-on treatment, but a full regimen is required. As for any malaria treatment, the regimen selection should not include the medication used for chemoprophylaxis.

When should malaria treatment be initiated?

Ideally malaria treatment should not be initiated until the diagnosis has been established by laboratory testing. “Presumptive treatment”, i.e., without prior laboratory confirmation, should be reserved for extreme circumstances, such as strong clinical suspicion of severe disease in a setting where prompt laboratory diagnosis is not available.

How often should you do a malaria smear?

In infections with P. falciparum, P. knowlesi, or suspected chloroquine-resistant P. vivax, blood smears should be repeated every 12–24 hours to monitor parasitological response to treatment, i.e., decrease in parasite density. It is recommended to document a negative malaria smear after treatment, but this could be done as an outpatient depending on clinical and parasitological response and the judgement of the treating clinician. Note that gametocytes, the sexual stage of the parasite, are not targeted by most of the antimalarials and should not be counted in assessing parasite density.

What is the best antimalarial for interim treatment?

The preferred antimalarial for interim oral treatment is artemether-lumefantrine (Coartem™) because of its fast onset of action. Other oral options include atovaquone-proguanil (Malarone™), quinine, and mefloquine. Intravenous or oral clindamycin and tetracyclines, such as doxycycline, are not adequate for interim treatment. These drugs are slow-acting antimalarials that would not take effect until well after 24 hours, and they are not effective antimalarials for treatment of severe malaria when used alone. As for any malaria treatment, the interim regimen should not include the medication used for chemoprophylaxis if possible.

How to determine malaria parasite density?

This can be done by looking at a monolayer of red blood cells (RBCs) on the thin smear using the oil immersion objective at 100x. The slide should be examined where the RBCs are more or less touching (approximately 400 RBCs per field). The parasite density can then be estimated from the percentage of infected RBCs, after counting 500 to 2,000 RBCs. Gametocytes, the sexual stage of the parasite, are not responsible for clinical symptoms and should not be counted when determining parasite density. More information on diagnostic procedures for malaria can be found on CDC’s DPDx website.

How often should you have a blood smear for malaria?

However, because non-immune individuals may be symptomatic at very low parasite densities which may be initially undetectable, blood smears should be repeated every 12–24 hours for a total of three sets before the diagnosis of malaria can be ruled out.

How to diagnose malaria?

Laboratory diagnosis of malaria can be made through microscopic examination of thick and thin blood smears. Thick blood smears are more sensitive in detecting malaria parasites because the blood is more concentrated allowing for a greater volume of blood to be examined; however, they are more difficult to read.

What does saliva do to a mosquito?

Mosquito saliva functions as an anticoagulant for the mosquito, preventing the female proboscis from becoming clogged by blood clots while feeding.

Why is malaria common in tropical areas?

Malaria is most common in tropical and subtropical regions because of a combination of high rainfall, high temperatures, high humidity, and large amounts of stagnant water where mosquito larvae readily mature, providing them with an environment they need for continuous breeding.

Where does malaria occur?

Malaria transmission occurs mostly in poor tropical and subtropical areas of the world (Figure 2) including many countries in central America, northern parts of South America, parts of Asia, and much of Africa.

Why are biofilm bacteria less susceptible to antibiotics?

a. biofilm bacteria are less susceptible to antibiotics because the drugs slowly penetrate the biofilm matrix. b. bacteria express different genes and exhibit a different phenotype when they are attached to surfaces in a biofilm. c. biofilm bacteria are often 1000x more susceptible to the effects of antibiotics compared to free-living bacteria.

c. a mixed culture will not grow in the conditions used in the assay

What is the best treatment for malaria during pregnancy?

Medications that can be used for the treatment of malaria in pregnancy include chloroquine, quinine, atovaquone-proguanil, clindamycin, mefloquine (avoid in first trimester), sulfadoxine-pyrimethamine (avoid in first trimester) and the artemisinins (see below). Briand et al compared the efficacy and safety of sulfadoxine-pyrimethamine to mefloquine for intermittent preventive treatment during pregnancy. In their study, 1601 women of all gravidities received either sulfadoxine-pyrimethamine (1500 mg of sulfadoxine and 75 mg of pyrimethamine) or mefloquine (15 mg/kg) in a single dose twice during pregnancy. There was a small advantage for mefloquine in terms of efficacy, although the incidence of side effects was higher with mefloquine than with sulfadoxine-pyrimethamine. [ 39, 40]

What is the trophozoite form?

This micrograph illustrates the trophozoite form, or immature-ring form, of the malarial parasite within peripheral erythrocytes. Red blood cells infected with trophozoites do not produce sequestrins and, therefore, are able to pass through the spleen.

Use during pregnancy may cause hemolytic anemia in a G6PD-deficient fetus. In addition, tafenoquine use during lactation should be avoided if the infant is G6PD deficient or of unknown G6PD status. [ 35] References.

Is artemether-lumefantrine as effective as quinine?

In a recent study in African patients, artemether-lumefantrine was as efficacious and as well tolerated as oral quinine in treating uncomplicated falciparum malaria during the second and third trimesters of pregnancy. [ 1]

Is tafenoquine safe during pregnancy?

[ 2] Use of tafenoquine to prevent relapse of P vivax malaria during pregnancy is not recommended. Use during pregnancy may cause hemolytic anemia in a G6PD-deficient fetus.
