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.

Is allergic purpura serious?

Firstly, allergic purpura is caused by infections, drugs, or food allergies leading to skin ecchymosis and petechiae; in addition, it can also manifest as joint pain, hematuria, and melena. The presence of protein in a routine urine test along with hematuria or melena often indicates gastrointestinal allergic purpura and renal allergic purpura. The presence of proteinuria suggests kidney involvement, which is the most severe type among various forms of allergic purpura. If it is solely a cutaneous type, no special treatment is needed other than drinking more water and ensuring bed rest to alleviate skin ecchymosis. If proteinuria or hematuria occurs, one must rest in bed until the protein levels improve before resuming activities. Concurrently, corticosteroids and anti-allergy medications should be administered. (Medication should be used under the guidance of a professional doctor.)

What medicine is taken for allergic purpura?

The medication for allergic purpura should be determined based on the severity of the patient's condition. If the patient only shows symptoms like rashes, the focus should be on reducing the rashes, and medications such as compound glycyrrhizin and desloratadine can be used for their anti-allergic effects. If the main clinical manifestation of allergic purpura is joint pain, some non-steroidal pain relief medications can be added for pain relief. However, if the patient primarily exhibits involvement of internal organs, such as gastrointestinal involvement in allergic purpura starting with abdominal pain, or kidney damage marked by significant proteinuria, then corticosteroids and immunosuppressants should be considered for treatment. (Please use medications under the guidance of a doctor).

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.

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.)
