What are the symptoms of immune deficiency in children

summary

A few days ago, I learned that my friend's baby was ill. After visiting, I learned that it was caused by immunodeficiency. Today, let me talk about children's immunodeficiency symptoms.

What are the symptoms of immune deficiency in children

First: infection, repeated infection is the most important and common clinical manifestations of immunodeficiency disease, severe cases can die of uncontrolled infection. The incidence rate of malignant tumors in tumors and congenital immunodeficiency is 100~300 times higher than that in normal persons. The incidence rate of malignant tumors is 100 times higher than that of ordinary people due to the use of immunosuppressive agents in renal transplantation.

Second, ataxia telangiectasia syndrome, characterized by progressive cerebellar ataxia and telangiectasia, which often occurs in the earlobe and bulbar conjunctiva. Elevated serum alpha fetoprotein was found in 95% of cases. The early immune deficiency was not obvious, and about 70% of the cases had abnormal immune function in the later stage. The levels of IgG2, IgG4, IgA and IgE were decreased or even absent, and the antibody reaction was decreased; the number and function of T cells were weakened, and repeated respiratory tract infection gradually appeared.

Third: allergy, due to immune dysfunction, the incidence rate of allergic diseases in immunodeficiency patients is higher than that in normal persons. Autoimmune diseases, due to immune dysfunction, imbalance, often lead to the occurrence of autoimmune diseases. From the clinical observation, secondary immunodeficiency occurs in the elderly, are temporary, eliminate the original cause, most can gradually recover.

matters needing attention

Children's immunodeficiency can be generally divided into two kinds, one is congenital immunodeficiency, which is due to pregnant women infected with the virus in the early pregnancy, and through the placenta caused by intrauterine infection of the fetus, resulting in congenital dysplasia of the fetal immune system. We should encourage every patient to use antibiotics reasonably, take good care of the patient's mentality, ensure the nutritional health of children, and avoid the infection of normal children.
