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 cured?

Allergic purpura is a common vasculitic hypersensitivity response, which means that it is a vascular inflammatory response caused by allergies and is particularly prevalent among adolescents, with a higher occurrence in males. Most cases are associated with infections or allergies, with the most common infections being bacterial, viral, parasitic, and mycoplasmal. Seafood and high protein can lead to allergies, triggering allergic purpura. This condition cannot be cured and tends to recur, but as individuals age and their immune system strengthens, the frequency and likelihood of episodes significantly decrease. However, if kidney damage occurs, which means the development of allergic purpura nephritis, it is crucial to regularly monitor kidney function and urine routine to check for the presence of proteinuria. If necessary, cardiac puncture should be performed, and corticosteroids should be administered.

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.)

Can people with allergic purpura take baths?

Patients with allergic purpura can take baths, but the water temperature should not be too hot. This is because excessive heat or vigorous exercise can potentially trigger a recurrence of allergic purpura. Additionally, patients should avoid getting cold to reduce the risk of infection, as infections can also provoke episodes of allergic purpura. During an episode of allergic purpura, it is necessary to take some anti-allergy medications and medications that reduce rashes, such as desloratadine dispersible tablets and compound glycyrrhizin tablets. If there is significant involvement of vital organs, such as the kidneys or gastrointestinal tract, some patients may also need to use corticosteroids. (Medication should be taken under the guidance of a doctor.)

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.)
