Allergic Purpura
What should I do if allergic purpura causes vomiting?
Patients with allergic purpura who experience symptoms of vomiting need to be highly vigilant to determine if it is the gastrointestinal type of allergic purpura. In addition to observing the vomiting, we also need to check for symptoms such as abdominal pain and diarrhea in the patient. Regarding treatment, we need to consider the use of corticosteroids. If the patient’s condition allows, immunosuppressants might also be needed. Dietary considerations are also very important; first, it is essential to maintain a light, liquid diet, avoid spicy or tough foods to manage the vomiting symptoms associated with allergic purpura. (The use of medications should be under the guidance of a professional doctor.)
How many days will allergic purpura take to fade?
The symptoms of the rash from allergic purpura generally subside naturally after about 7 to 10 days. However, if care is not taken in daily life, there is a high likelihood of recurrence of the rash. Patients with allergic purpura should avoid vigorous activities such as fast running and should also avoid getting chilled and infections, as both cold and infections could exacerbate the condition. Additionally, patients should consume less of foods like shrimp and crab, which may trigger allergic reactions.
Precursors of recurrent allergic purpura
The precursors of a relapse of allergic purpura typically occur in patients after exposure to cold, strenuous exercise, or allergens, manifesting as purpuric rash on the skin. Additionally, some patients may experience gastrointestinal reactions such as nausea, vomiting, abdominal pain, and diarrhea. More severe cases can present with symptoms of allergic purpura and purpura nephritis, primarily characterized by edema and significant proteinuria indicated in routine urine tests. If patients experience the aforementioned symptoms, it is crucial to be vigilant about the possibility of a relapse of allergic purpura and to seek medical attention promptly to prevent further progression of the disease.
Can people with allergic purpura eat chicken?
Patients with allergic purpura can eat chicken. In the diet of patients with allergic purpura, the general principle is to try to reduce the consumption of spicy foods and some potential irritants such as celery, coriander, and shiitake mushrooms, which should be eaten sparingly. Chicken is not considered an irritant and can be consumed. In addition to strict dietary precautions to avoid allergens, patients with allergic purpura should also avoid vigorous exercise and strictly avoid getting cold and infections, as both vigorous exercise and infections can potentially trigger acute episodes of allergic purpura.
Does allergic purpura spread to others?
Firstly, allergic purpura is neither a genetic nor a contagious disease, so there is no need to worry about it being inherited or transmitted to others. It is an allergic reaction caused by drugs, food, or infections, typically manifested by bleeding and bruising on the skin and mucous membranes of the limbs, joint pain, and hematuria. Diagnosis requires the combination of clinical manifestations and related tests such as urinalysis. If it is merely a case of the skin type, it only necessitates bed rest and observation of the number and extent of bleeding points on the skin and mucous membranes without special treatment. If there are symptoms like black stools or proteinuria, bed rest is imperative along with the use of anti-allergy medications or corticosteroids to enhance treatment, continuing until the proteinuria resolves.
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.
