What is schistosomiasis and is there a cure?

If it is acute or advanced, it is possible to ** if it is acute (**drug: praziquantel), if it is advanced or chronic (mainly due to repeated acute **infection or repeated **incomplete), it is more difficult.

Schistosomiasis is a chronic human parasitic disease, schistosomiasis is very harmful to human health, especially in Africa, and has harmed countless lives. There are two main types of schistosomiasis, among which intestinal schistosomiasis is caused by Schistosoma mansoni and Schistosoma japonicum, and urinary tract schistosomiasis is caused by Schistosoma haematosis, so how is schistosomiasis**? Can schistosomiasis be cured?

1. How to schistosomiasis

Schistosomiasis can cause damage to the human body whether it is cercariae, larvae, adults or eggs, but eggs are the most harmful to people, and the live eggs in the feces of schistosomiasis patients are the main source of infection and the cause of schistosomiasis. Schistosoma eggs settle in the intestinal wall tissues of humans and form cell infiltration, resulting in granulomas of the eggs, which in turn cause lesions of the large intestine and liver.

When the eggs develop into caterae, the reaction of the intestinal wall tissue is very slight, and after the formation and maturity of the larvae, the intestinal wall tissue begins to appear in the open air, and after the larvae mature, it will directly lead to tissue necrosis and acute inflammatory reaction. In general, endovascular endocarditis and eosinophilic abscess are often present in the egg collection in patients, and neutrophil abscess can also be infected in severe cases.

In addition to egg infection, another cause of schistosomiasis is schistosomiasis caused by human ** or mucous membranes in contact with water contaminated by schistosomiasis, and general vertebrates, including humans, are not immune to schistosomiasis.

At present, for schistosomiasis, most of them use praziquantel, and artemether pills and artesunate are also used in some places. Schistosomiasis prevention is currently largely prevented by humans. For example, reduce playing in freshwater areas, avoid contact with water areas where snails are stored, or carry out **protection before entering polluted waters, avoid **infection, and timely check and carry out early ** after leaving the water.

2. Pathogen examination

Eggs are examined from the stool or hatched larvae and rectal mucosal biopsies.

1) Schistosoma eggs can often be detected in the feces of patients in severely infected areas or in the mucus and blood of patients with acute schistosomiasis in the areas of severe infection by direct smear, and the method is simple, but the detection rate of eggs is low.

2) The larvae hatching method can improve the positive detection rate.

3) Quantitative transparent method is used for schistosomiasis egg counting.

4) Rectal mucosal biopsy: Chronic and advanced schistosomiasis patients have thickened intestinal wall tissue, and the slow discharge of eggs is blocked, so it is not easy to find eggs in the feces, and proctoscopy can be applied.

3. Diet for schistosomiasis

1。Acute schistosomiasis.

50 grams of pumpkin seeds, peel and leave the kernels, grind, add boiling water, honey or sugar to make a paste, and take on an empty stomach. This formula has the effect of detoxification and insecticide.

2。Acute schistosomiasis.

1500 grams of jujube betel nut, 100 grams of quince meat, 300 grams of madder root, 300 grams of red vine, and 10 grams of realgar for those who belong to the liver and spleen dampness and heat. In addition to the red vine, the rest of the four flavors are finely ground together, and the red vine is thickly fried to extract the juice pan pills, such as the size of peppercorns, and used beeswax as the coat. 20 grams daily, divided into 2 doses.

This formula has the effect of clearing away heat and dampness and detoxifying.

3。Chronic schistosomiasis.

For those with diarrhea, 50 grams of rice, 30 grams of yams, and white lentils.

Schistosomiasis can not belong to the misunderstanding of the disease among the public, in fact, schistosomiasis can be cured, and it will not**. It is essentially a parasitic disease, as long as the adult worms in the body are killed, and no longer come into contact with the infected water. The folk believe that schistosomiasis cannot be **, mainly in the following aspects:

First, in the schistosomiasis-plagued area, the people come into contact with the infected water again after **, and the infection occurs again, and they get it again after treatment, so there are diseases every year. Second, every year, the blood prevention department investigates the disease mainly by taking blood tests, which are checked for the corresponding antibodies, and many adult worms have died through **, but the antibody titer has not turned negative, and they are still treated as chronic patients. Third, people who have been infected with schistosomiasis have been completely affected by **, but the liver connective tissue hyperplasia caused by ** is irreversible, and the pat** shows schistosomiasis liver, which makes people mistakenly think that schistosomiasis is not yet cured.

Fourth, complications of advanced schistosomiasis, such as upper gastrointestinal bleeding, persist, make people feel that schistosomiasis cannot be broken.

Therefore, don't be too afraid of schistosomiasis, it can be prevented and treated, and it can't be said to be unscientific. The key is to detect it early, and it will be no problem to be cured. It is important to remember that you will not be infected with schistosomiasis if you do not come into contact with infected water.

BR>Schistosomiasis is a parasitic disease caused by adult schistosomiasis parasitizing the human venous system. Humans are infected by contact with infected water containing cercariae. Men and women can be infected, but young people, middle-aged people, farmers and fishermen account for the majority, and summer and autumn are the most susceptible to infection.

Western medicine** Praziquantel: This drug has the advantages of high efficacy, low toxicity, mild reaction, short course of treatment, and convenient to take. The total dose of acute schistosomiasis is calculated as 120 mg kg, divided into 12 doses and 4 days.

The total dose of chronic schistosomiasis is calculated as 60 mg kg, which is taken in 6 doses of 2 days. Nithimelamine (7505): the efficacy is not as good as that of viraquinone, and the reaction is larger, and it is currently more used for schistosomiasis in cattle.

The total dose is 6-7 mg kg, in 3 aliquots, 1 time per day. Traditional Chinese Medicine** Traditional Chinese medicine can use a single prescription, such as compound betel nut tablets (jujube paste, betel nut, realgar, madder, red vine)**Chronic schistosomiasis. Lobelia 45g, decoction in water, 15 days for 1 course of treatment, ** advanced patients with ascites.

Nursing Acute patients should be on bed rest. Eat more protein and less fatty diet, and the patient's feces should be treated separately to prevent contamination of water sources and epidemics.

Schistosomiasis can be **, and there are drugs in local centers for disease control and prevention, mainly the anthelmintic drug praziquantel, which is safer to take two capsules at a time. **If there is a reaction, it should be treated symptomatically.

Patients with advanced schistosomiasis have an enlarged spleen and have a splenectomy.

Acute infection patients have fever, pus and bloody stools, **same as above. After becoming chronic, patients are emaciated, children are not developed, women have stopped menoprhevosus, and in the advanced stage splenomegaly forms ascites, and the hepatic portal vein rupture causes massive bleeding.

Schistosomiasis patients defecate when the eggs enter the water to form larvae, which burrow into the snail and develop into cercariae, and mature cercariae swim in the water to form infested water. When the human body comes into contact with the water, the larvae burrow through the ** into the human body, and after migration, they develop into adult worms in the blood vessels. Adult worms grow and ovulate in blood vessels, absorb nutrients, and the worm body and eggs can also block blood vessels.

Some eggs flow through the bloodstream to the intestinal wall, releasing enzymes to dissolve the intestinal wall, and the intestinal wall is also damaged, causing lesions. The eggs are excreted in the feces and complete a cycle.

Prevention is mainly aimed at three links;

Do not come into contact with infected water.

Destroy the intermediate host snail.

Schistosomiasis is investigated and the source of infection is eliminated.

Hello!Schistosomiasis ** Principles:

1) Chronic schistosomiasis:

Praziquantel 40mg kg at once or divided into two doses a day.

2) Acute schistosomiasis:

Praziquantel 120 mg kg (140 mg kg for children) for 6 days**, and those with more severe disease can be treated with supportive and symptomatic ** to improve the physical condition before being the pathogen**.

3) Advanced schistosomiasis:

The main pathogen is to improve symptoms, control and prevent complications. In addition to complicated upper gastrointestinal bleeding, high-grade ascites, and hepatic coma, a total of 60 mg of praziquantel can be taken orally in 3 to 6 divided doses within l to 2 days. Complications** can be a combination of traditional Chinese and Western medicine, medical and surgical combinations**.

The pathogen can be completely cured, but most of the pathological changes caused by it cannot be recovered.

Schistosomiasis is a parasitic disease caused by schistosomiasis. Chronic patients mainly present with fatigue, abdominal pain, intermittent diarrhea or dysentery-like stool, obvious enlargement of the liver and spleen, and late schistosomiasis cirrhosis, giant spleen, and ascites. Multiple repeated infections in childhood can cause schistosomiasis dwarfism.

Cerebral schistosomiasis may present with symptomatic epilepsy and mass lesions. The pathogen is the main one, and praziquantel is the preferred drug.

After **, schistosomiasis can be completely killed. Symptoms such as fatigue, abdominal pain, and diarrhea may disappear. Hepatosplenomegaly can be recovered to some extent. However, most of the cirrhosis caused by advanced stages, ascites, and childhood dwarfism are irreversible, but ascites can be alleviated.

1. The first agent of schistosomiasis.

Schistosoma is mainly a live egg in the feces, and usually when people go to the waters, they are infected through the **, mucous membranes and infected water areas, which endangers human health and should be paid attention to.

When a person's ** comes into direct contact with the infected water containing the larvae of schistosomiasis, he will be infected and will get sick. People who depend on agriculture and fishing for a living may come into contact with this polluted water source, so they may get sick.

Schistosomiasis is caused by human exposure to schistosomiasis infection, such as contact with infected water containing cercariae or schistosomiasis patients, and the common schistosomiasis in our country is Schistosoma japonicum.

It is caused by contact with water contaminated with cercariae. Patients with schistosomiasis, in normal times, we must do some emergency treatment, adrenocorticosteroids can be used to help patients relieve the symptoms of poisoning, are to cool down.

It should be infected by the source of infection, the main source of infection is schistosomiasis, if you often drink some unhygienic water or have contact with patients with schistosomiasis, you are prone to infection.

Schistosomes are mainly caused by eggs. Granulomas and fibrosis caused by eggs mainly deposited in the liver, colon and intestinal wall of the host are the main lesions of schistosomiasis.

It can be seen from the transmission process of schistosomiasis that the following basic links must be present to constitute an epidemic of schistosomiasis: 1. Eggs are discharged by patients and sick animals; 2. The eggs enter the water and hatch the larvae; 3. The larvae burrow into the body of the snail and develop into cercariae, and escape from the body of the snail and float on the water surface; 4. Human or mammalian contact with infected water. Therefore, schistosomiasis control measures should be aimed at these basic links.

Specifically, first, it is necessary to actively investigate and treat sick animals and sick animals. Simultaneous inspection of humans and animals should be carried out to control the source of infection.

The second is to identify and eliminate snails, which are a link that must pass through the transmission process of schistosomiasis, without which schistosomiasis cannot survive, reproduce and spread, and it is impossible to cause the epidemic and harm of schistosomiasis.

In addition, it can be seen from the transmission process of schistosomiasis that a larvae burrows into the body of the snail and can release thousands of cercariae after breeding, so the snail is actually a "transit station" and "gas station" for the epidemic of schistosomiasis, so the elimination of the snail has become the main measure to eliminate schistosomiasis. The third is to do a good job of personal protection, avoid contact with infected water, and prevent infection When it is necessary to contact infected water, use protective equipment. Fourth, it is necessary to strengthen fecal management and carry out harmless treatment to prevent feces from polluting water sources, and also kill schistosomiasis eggs in feces.

This is how schistosomiasis is transmitted.

What is a snail and what are its morphological characteristics?

The snail is an amphibious freshwater organism that is an oviparous snail. The snail is very small, the length is generally not more than l cm, and the width is not more than o 4 cm, just like a small shoe spike, so it is called a snail.
