Why can t allergens be detected in Henoch Schonlein purpura?

Because the allergen is now limited in medical investigation, it can not be completely investigated, the second is that it does not make much sense to check the allergen, this disease is a kind of hemorrhage caused by immune stress response, because there are many, some are caused by allergens, some are caused by colds, some are caused by vaccines, not only caused by allergies, so it can not be checked, but it is not terrible to have this disease, this disease can be cured, you can go to Beijing to find Professor Zhang Guangrui, he is a Chinese medicine in my country** He is an authoritative expert in hematology, and he is the chief expert of the Chinese medicine hematology specialty of Beijing Huajun Hospital of Traditional Chinese Medicine affiliated to the International Academy of Life Medicine Engineering of China.

The allergen test is only a part of the substances in daily life, which is limited and related to the medication at the time, so it is possible that the allergen test is negative, that is, the allergen cannot be detected. This disease is a deficiency of the human immune mechanism, and thoroughness is the fundamental. The disease is characterized by its tendency to recur and its variability.

Therefore, it is necessary to actively take symptomatic measures.

I'm also allergic to purpura, allergic to cooked food, I haven't eaten cooked food for a year, and I haven't committed it again.

No way, I have too, my allergen is a drug allergy.

If your child has suspected Henoch-Schonlein purpura, but parents are unable to confirm whether they have the disease, they need to go to the hospital for relevant tests.

Henoch-Schonlein purpura can be detected by many routine examinations, such as three routines, liver and kidney function, coagulation tests, immunological tests, kidney ultrasound, etc., if the kidney damage is severe, renal puncture examination should be performed if necessary. Among them, urine routine, 24-hour urine protein quantification, and urine discharge examination are more important, and repeated examinations are required. Because these tests can help detect kidney damage in children early, get the system early, and prevent the progression of the disease.

Henoch-Schonlein purpura routine examination items and results are judged as follows:

1. Blood routine: unless there is severe bleeding, there is generally no anemia, platelet count is normal or mildly high, and white blood cell count is normal or mildly high.

2. Routine stool: some children can see red blood cells or parasite eggs, and the occult blood test can be positive. Intestinal bleeding can be determined.

3. Urine routine: children with allergic purpura nephritis may have urine protein, red blood cells, white blood cells and casts. A preliminary diagnosis of kidney damage can be made.

In addition, if the child is seriously ill, you can also check the condition through surgery such as kidney puncture to find out the appropriate method.

I can check, I am from Harbin, and I can check it in our provincial hospital, more than 500 yuan, and more than 700 items can be checked.

1. Those who will be allergic can't eat it, and it is best not to touch it.

2. There are two items to check allergens, one is to draw blood, mainly to check contact, such as dust, pollen, etc., and the other is to check food, such as garlic. Generally, you can find out.

Abdominal Henoch-Schonlein purpura is based on ** or mucosal purpura, accompanied by gastrointestinal symptoms. Such as abdominal pain, vomiting, blood in the stool, or melena, or even intussusception. The principle is that purpura also appears on the gastrointestinal mucosa.

Through **, the patient's abdominal pain, vomiting and other symptoms disappeared, **purpura subsided, and there was no urine abnormality in the urine routine examination. However, even if all the symptoms disappear, the patient should not relax his vigilance, and should do a good job of daily care, stay away from **, and avoid the reversal of the disease.

Henoch-Schonlein purpura causes this disease** mainly due to allergies and exposure to allergens. Diagnosis is clinical. After the diagnosis is confirmed, you can actively use hormones and other related drugs to fight allergies**.

And be careful to avoid contact with allergens.

Most of them have **purpura as the first symptom. Skin lesions appear as pinhead-to-soybean-sized petechiae, ecchymosis or urticaria-like rashes, or pink maculopapular rashes that do not fade when pressed, and purpura is the episodic lesion. Purpura can fuse into patches and eventually turn brown.

It usually fades within 1 to 2 weeks without leaving a trace. In severe cases, blisters, blood blisters, necrosis and even ulcers may occur. The rash usually occurs in weight-bearing areas and is more likely to occur on the extensor sides of the extremities, especially on the lower extremities, around the ankle joints, and on the buttocks.

Lesions are symmetrically distributed, appear in groups, and are prone to **.

First of all, you should abstain from all kinds of allergies. Allergies are a major cause of this disease, and many of the allogeneic proteins can cause allergic purpura, mainly fish, shrimp, crab, egg, milk, broad bean, pineapple, etc. Once the patient finds a certain sensitizing effect, he or she should contrause it for life, and should not use cooking utensils and utensils that have been in contact with it.

In addition, it is advisable for people with Henoch-Schonlein purpura not to eat vegetables such as new flower buds that they have never eaten, as plant pollen has also been reported to be a common allergen.

Secondly, patients with Henoch-Schonlein purpura often suffer from anemia due to excessive bleeding, so it is necessary to eat more protein-rich and blood-replenishing foods to supplement the body's needs. These mainly include lean meat, poultry eggs, animal liver, kidney, spinach, tomatoes, kelp, seaweed, fungus, jujubes and beans and their products.

In addition, you should eat more high C, C has the effect of reducing capillary permeability and fragility, and patients should eat more of these to help **. C-rich grapefruits, oranges, citrus, apples, lemons, strawberries, kiwifruit, tomatoes, and a variety of leafy greens.

It is worth noting that patients with Henoch-Schonlein purpura should not only supplement a variety of supplements, but also try to make it lighter, and those with kidney damage should limit the intake of salt and water.

Go to the hospital for a lab test, and judge that you are allergic to those things according to the test sheet given to you by the hospital, and it is much better not to touch them in the future, which is very troublesome.

Diagnostic criteria 1, routine blood examination: mild to moderate increase in blood cells, normal or increased eosinophils, blood loss can be more anemia, coagulation time, platelet count, blood clot contraction time are normal. 2. Erythrocyte sedimentation rate:

In most patients, the blood sedimentation rate increases rapidly3, anti-O: can be increased 4, serum immunoglobulin: serum LGA can be increased 5, urine routine:

In patients with renal involvement, protein red blood cells or casts may appear in the urine. 6. Blood urea nitrogen and kegan: increase in renal insufficiency 7. Fecal occult blood:

Positive type in gastrointestinal bleeding 8, capillary fragility test: positive in about half of patients 9, kidney tissue biopsy: can determine the nature of nephritis lesions, which is of guiding significance for the determination of ** and prognosis.

Key points of diagnosis 1: There is a history of infection, food, drugs, pollen, insect bites, vaccinations, etc. 2. There are typical characteristic ** purpura, combined with joint, gastrointestinal or renal symptoms and a history of anti-**. 3. Whole blood leukocytes and eosinophils are increased, and when bleeding is severe, red blood cells and hemoglobin are reduced.

4.Erythrocyte sedimentation rate, CPR

may be positive, serum IgA

Heighten. 5.In the presence of renal impairment, hematuria and proteinuria may be seen. Auxiliary examination 1, blood test: no anemia, normal platelet count, normal or slightly elevated white blood cell count, normal coagulation time. 2、

Bone marrow image: normal bone marrow like eosinophils may be high. 3. Urine test:

There may be albumen red blood cells, white blood cells, and casts. 4. Routine fecal examination: some patients can see parasite eggs and red blood cell occult blood test.

5. Capillary fragility test: positive 6. Pathological examination: diffuse perivascular inflammation neutrophils accumulate around blood vessels.

Immunofluorescence studies show IgA and C3 deposition in the dermal vessel wall. Differential diagnosis 1, idiopathic thrombocytopenic purpura.

It is not difficult to distinguish purpura according to the fact that the morphology of purpura is not high, the distribution is asymmetrical and the platelet count is reduced. Henoch-Schonlein purpura rash is more distinguishable if accompanied by angioedema, urticaria, or erythema multiforme. 2. Sepsis.

The rash caused by meningococcal sepsis is similar to that of purpura, but the symptoms of poisoning are severe, the white blood cells are significantly increased, and the smear at the puncture site of the rash may be positive. 3. Rheumatoid arthritis.

Both can have joint swelling and pain and low-grade fever, which is difficult to distinguish before the appearance of purpura, and as the disease progresses, the appearance of purpura is helpful to distinguish. 4. Intussusception.

It is more common in infants and young children. If the child cries and has a palpable mass in the abdomen, the abdominal muscles are tense. Barium enema fluoroscopy can be differentiated. However, Henoch-Schonlein purpura can be accompanied by intussusception, so it should be noted. 5. Appendicitis.

Both may present with periumbilical and right lower quadrant pain with tenderness. However, the abdominal muscles of Henoch-Schonlein purpura are not tense, and there is purpura, which can be distinguished.

Purpura: Mostly caused by thrombocytopenia or drug allergies. The symptoms are internal bleeding such as **, mucous membranes, etc., and purple scars on **.

In Henoch-Schonlein purpura, the allergen should first be identified, and the determination of the allergen is conducive to targeting**.

In a Chinese medicine query network, I saw: Henoch-Schonlein purpura, you can take Angelica pills. Angelica pills, which have the effect of enhancing immunity, are clinically used for various anemias, allergic purpura and other people with blood deficiency and qi weakness.

1.Routine blood tests: normal or elevated platelet count; The bleeding time, coagulation time, blood clot retraction time and prothrombin time were normal; The white blood cell count is normal or mildly elevated, and in some patients the total white blood cell count is elevated, with a left shift, and the erythrocyte sedimentation rate may be increased, and there is usually no anemia unless there is severe bleeding.

2.Infection and etiological examination: Elevated C-reactive protein and antistreptolysin may be positive, and pharyngeal culture may show hemolytic streptococcus.

3.Immunological examination: antinuclear antibody and rheumatoid factor are often negative; Some patients have elevated serum IgA, IgG and IgM are normal, and IgA begins to increase 2 weeks after the onset of symptoms, C3, C4, and CH50 are mostly normal or increased, and interleukin 6 (IL-6) and tumor necrosis factor (TNF-A) are elevated.

4.Urinalysis: Henoch-Schonlein purpura nephritis may have urine protein, red blood cells, white blood cells and casts, which can preliminarily determine whether the kidneys are damaged. Microscopic hematuria and gross hematuria may occur in renal involvement, and sometimes severe proteinuria can cause hypoproteinemia.

5.Urine Release: Measure the composition of urine protein, which can reflect damage to the glomeruli and renal tubules.

6.Renal function ultrasound: It can observe various lesions in the kidney and its surroundings, and the examination is rapid and reproducible, which is an ideal examination method.

7.Routine stool: red blood cells or parasite eggs may be seen in some patients, and a positive occult blood test can determine the presence of intestinal bleeding.

8.Five coagulation items: most patients with purpura may have hypercoagulable blood, which is not conducive to recovery from kidney damage.

Hourly urine protein quantification: Accurately measure the total amount of protein excreted in 24-hour urine, which can accurately assess the degree of kidney damage.

What kind of tests should I do if I have Henoch-Schonlein purpura? Blood routine, urine routine, this is the most basic, some people say, Henoch-Schonlein purpura, why do blood routine, because eosinophils are high, there will be a situation that indicates that your body is in allergies. Combined with your allergy history, if the urine routine is positive for urine protein (plus:

The more pluses, the more severe), indicating the formation of purpuric nephritis.

But it doesn't seem to be serious, hold on**.

It is not difficult to diagnose patients with typical symptoms such as purpura of both lower extremities, abdominal pain, arthralgia, or renal damage.

To control allergic foods, it is advisable to eat more foods high in vitamin C, vitamin K, and high in plant protein.

When systemic symptoms such as joint pain and abdominal pain precede purpura, it is easy to misdiagnose rheumatoid arthritis or acute abdomen, and it is necessary to distinguish these diseases from other types of purpura and vasculitis.
