Allergic Purpura
Does allergic purpura cause vomiting?
Patients with allergic purpura may experience symptoms of vomiting. Patients with the gastrointestinal type of allergic purpura may exhibit symptoms such as vomiting, abdominal pain, and diarrhea. The gastrointestinal type is considered a severe form of allergic purpura because it affects critical internal organs and the intestines. In treatment, besides using anti-allergic methods to reduce rashes, it is also necessary to use corticosteroids to reduce inflammation and control gastrointestinal symptoms. Additionally, immunosuppressants such as mycophenolate mofetil can be used to control the gastrointestinal response. Meanwhile, patients should adhere to a strict fasting regimen until symptoms like vomiting and diarrhea improve. (Medication should be administered under the guidance of a professional doctor.)
Can allergic purpura be cured?
Allergic purpura mainly occurs in adolescents and children, often in the spring and autumn seasons, and is typically related to bacterial infections, viral infections, and allergies to medications and foods. The most common clinical symptoms include bruises on both lower limbs, bleeding, black stools, joint pain, and abdominal pain. Upon the appearance of bruises on the lower limbs, it is recommended to complete routine blood tests, erythrocyte sedimentation rate, and autoantibody tests to rule out other autoimmune diseases causing skin bruises. During the acute phase, it is necessary to rest in bed, drink plenty of water, and eat a light diet. If there are only simple skin bruises, these may resolve after rest. However, if joint pain, bloody stools, and black stools occur, formal and active treatment is required, as these symptoms will not resolve on their own. Additionally, the presence of blood or protein in urine suggests kidney involvement, indicating that the condition has worsened.
Can allergic purpura be cured completely?
Allergic purpura is a special type of vasculitis and also a hypersensitivity disorder. It commonly occurs in adolescents and children aged 5 to 14, with a higher incidence rate in the spring and autumn seasons. The disease frequently relapses and cannot be completely cured. The most common causes of allergic purpura include infections, medications, and foods. Infections are the most frequent cause, such as bacteria, viruses, parasites, tuberculosis, etc. If it is merely a cutaneous form, no special treatment is required at this time, and bed rest alone can alleviate the condition. If there is the presence of blood or protein in the urine, and renal biopsy shows a large number of crescents, it then indicates a serious aggravation of the condition.
Are there many children with allergic purpura?
Firstly, allergic purpura is commonly found in adolescents and children, with children being the most commonly affected, particularly between the ages of 8 to 15. It typically occurs during the spring and autumn seasons. The most common clinical manifestations are bleeding spots on the lower limbs, hematuria, black stools, and joint pain, which are the most typical clinical presentations. If there are only bleeding spots on the skin, no special treatment is required at this time; rest in bed is necessary, and these bruises can be absorbed. Once the kidneys are involved, it indicates a relatively severe condition, and at this time, active and standard treatment is necessary, including the need to improve routine urine and kidney function indicators. If protein quantification is relatively high, then glucocorticoids are needed, combined with anti-allergic medication. (Medication should be taken under the guidance of a doctor.)
Is allergic purpura nephritis contagious?
Henoch-Schönlein purpura nephritis and allergic purpura are not infectious diseases; there is no contagious element involved. Henoch-Schönlein purpura nephritis is actually kidney damage caused by allergic purpura, which is an allergic disease itself. Patients suffer from an abnormal immune response in the body’s immune system after coming into contact with allergenic drugs or foods, leading to necrotizing vasculitis. This disease is unrelated to pathogens. Generally, there is no direct damage to the kidneys caused by a specific pathogen in this disease, nor do patients carry pathogens that can cause Henoch-Schönlein purpura nephritis, such as bacteria or viruses, thus making the disease non-contagious.
Is allergic purpura with abdominal pain easy to treat?
Allergic purpura with abdominal pain, also known as abdominal allergic purpura, involves gastrointestinal symptoms associated with allergic purpura, primarily characterized by episodic severe abdominal pain, usually around the navel or lower abdomen, and may sometimes be accompanied by vomiting. Treatment typically involves bed rest, actively identifying the cause, controlling infections, and supplementing relevant vitamins. It's also important to check for any symptoms of gastrointestinal bleeding. If there are signs of gastrointestinal bleeding, strict dietary management is necessary, blood transfusions may be required when needed, and the healing of the gastrointestinal tract must be monitored. Medications to suppress acid or protect the gastric mucosa could be considered. Generally, the prognosis for allergic purpura is favorable, though very few severe cases may experience gastrointestinal complications such as bleeding, intussusception, or even necrosis. Although the prognosis is generally good, relapse is common. (Please use medications under the guidance of a professional physician and do not self-medicate.)
Is allergic purpura nephritis contagious?
Kidney damage caused by allergic purpura is called allergic purpuric nephritis. The main mechanism of allergic purpuric nephritis is the deposition of immune complexes in the kidneys, causing hematuria, proteinuria, edema, and hypertension. Severe cases of purpuric nephritis may also lead to renal failure. Additionally, patients with allergic purpuric nephritis exhibit systemic symptoms such as skin purpura, abdominal pain, joint pain, and melena. Allergic purpuric nephritis usually occurs in children, and it is not contagious. Unlike viral hepatitis, tuberculosis, and dysentery, it does not spread through respiratory, digestive, or blood pathways.
Can allergic purpura be inherited?
Allergic purpura is mostly caused by exposure to infections, medications, or foods, leading to skin and mucous membrane ecchymoses, which are essentially petechiae and a manifestation of vasculitis. It falls under autoimmune diseases, not genetic diseases, and thus is not contagious. Bacterial, viral, mycoplasmal, or parasitic infections are the most common causes. Secondarily, medications and foods can also trigger allergic purpura, such as high-protein foods like seafood and milk. Therefore, if there are symptoms like ecchymoses on the lower extremities accompanied by joint pain, or signs of blood in the stool or black stool, it is necessary to complete routine blood tests, erythrocyte sedimentation rate, and autoimmune antibody tests to rule out other autoimmune diseases. During the acute phase, it is advisable to rest in bed, eat a light diet, avoid infection, and use corticosteroids for anti-allergy treatment if necessary.
Can allergic purpura cause itching?
Allergic purpura is mainly seen in adolescents and children, with a higher incidence in spring and autumn. The most common cause is infection, followed by medications or food, which can also trigger an episode of allergic purpura. The most common symptoms include purpura on the skin and mucous membranes, abdominal pain, blood in stools, hematuria, or joint pain. The purpura primarily affects the limbs, rarely appears on the trunk, and is symmetrically distributed. At this time, the bleeding spots often have no symptoms, meaning there is no itching of the skin. However, when there is concomitant skin edema or hives, itching can occur.
Mild symptoms of allergic purpura
Allergic purpura mainly includes three pathological types. The symptoms of the mild type mainly involve changes in the skin, primarily purpura-like rashes around the lower legs and ankle joints. If there are only skin lesions, it is considered a very mild case of allergic purpura. Additionally, more severe cases may involve kidney impairment, such as the presence of protein in the urine. Some patients primarily experience joint pain, also known as the arthritic type. Another group of patients presents mainly with sudden abdominal pain, primarily known as the abdominal type. Therefore, mild symptoms of allergic purpura might just be typical rashes. As long as there is no involvement of the visceral system, it is considered relatively mild.
