After the mosquito bites, the rash is still abdominal pain?This situation is visited in time

Seemingly ordinary mosquito bites can also cause the hospitalization of hospitalization, which can not only cause rash and abdominal pain, but also hematuria. What exactly is going on? Today, the doctor will talk to you about vasculitis caused by bites.

Abdominal pain caused by the bite of the worm

Ms. Tan recently encountered trouble. She was bitten by mosquitoes in her two legs a week ago. Later, local skin redness and swelling appeared. However, the scope of redness is further expanding, and then there are multiple purple -red rashes in both calfs, and the color cannot be returned. Considering that the temperature is normal, there are no other uncomfortable symptoms. I wanted to wait for the rash to subscribe by itself, but I didn't see it, so I hurried to the hospital.

For purple -red rashes, it is not aggressive, and clinically we are generally called pimple -like purpura. The inflammation response of the local skin redness and swelling of the calf of the calf is also obvious. The doctor saw this quickly improve the patient's routine examination and found that the count of white blood cells and neutral granulocytes increased. Seeing this, considering the possibility of allergic purpura, there is also the possibility of soft skin tissue infection, and oral antibiotics and anti -allergic drugs are given.

However, a wave of unrest and waves, Ms. Tan subsequently had new symptoms -abdominal pain, and the rash also became more, and similar pimple -like purpura also appeared on both upper limbs and thighs.

After hospitalization, the doctor perfected the blood IGA examination for Ms. Tan, and the level was higher than the normal value. Considering that Ms. Tan suffered from allergic purpura, it may be related to the infection and immune disorders caused by mosquito bites. Abdominal pain improved significantly, and the rice could be eaten, and Ms. Tan finally smiled.

Such vasculitis

Most happened to children

So what is the disease of allergic purpura? In fact, allergic purpura is an old name. With the development of medicine, after understanding the disease mechanism, it is now called IgA (immunoglobulin A) vasculitis, which is an immune -related vasculitis related to IgA deposition. At present, it is found that the disease may be related to factors such as infection, vaccination, immune disorders, food and drugs, and genetic factors, but it has not been fully clarified that 90%of them occur in children, and adults may also be sick.

Its common clinical manifestations include non -platelet reduction of trigger purpura, abdominal pain, gastrointestinal bleeding, joint pain, and kidney damage:

Before the formation of a typical purpura, the skin may be a rash similar to urticaria or red pimples, manifested as symmetrical distribution of limbs or hips.

About 82%of joint symptoms have joint affected by joints, and the lower limbs are the main joints, especially the ankle joints and knee joints.

Gastrointestinal symptoms are greater than 1/2 to 3/4 patients with abdominal pain or vomiting. In severe cases, gastrointestinal bleeding, intestinal obstruction, and intestinal perforation may occur.

The incidence of kidney damage is about 20%-60%, and there may be acute renal failure in the naked eye hematuria, mirror hematuria and proteinuria.

There are common symptoms of rash

There are many mosquitoes in summer and autumn, and itching rash in bites is very common, but if the rash is ecchymosis, you need to be alert to allergic purpura. In addition, allergies are particularly paid to avoid contact with allergens. If you have discomfort such as ecchymal rash, abdominal pain, joint swelling and pain, hematuria, and increased urine foam, you will go to the hospital in time to avoid delaying the condition.

If IgA vasculitis is suffering from IgA vasculitis, there is often no different performance when conventional blood tests such as blood routine and biochemical examination. 50%-70%of patients will have a raised serum IGA, and usually doctors can make judgments based on characteristic skin lesions. Most patients can heal themselves for such vasculitis. However, patients with severe rash, acute joint pain, abdominal pain, and renal damage should be visited in time to control acute phase symptoms and monitor important organic functions.
