List of common immune system diseases

The immune system is the body's defense mechanism against various diseases and infections When the human body is invaded by foreign things, the immune system will take measures to completely destroy them There are many bacteria, viruses and other harmful foreign bodies that can easily cause fatal infection The human immune system can produce specific antibodies against these microorganisms Because without the protection of the immune system, we will all be victims of infection or other problems However, the immune system function to resist diseases may be damaged by many diseases and disorders Based on the activity of the immune system, the following gives a detailed list of common immune system diseases: immune system inactive immune system hyperactive immune deficiency disease: This is a large group of immune system diseases composed of different diseases that inhibit the immune system Immunodeficiency diseases are usually caused by underlying chronic diseases The symptoms of immunodeficiency diseases are the same as those of underlying diseases Severe combined immunodeficiency: it is a hereditary immune system disease The causes of SCID include a series of genetic abnormalities (especially chromosomes) Some types of recurrent infection are common in patients with severe combined immunodeficiency In addition, they are more likely to suffer from meningitis, pneumonia, measles, varicella, herpes, oral candidiasis and blood diseases Children with severe combined immunodeficiency become apparent three months after birth AIDS: This is a serious immune system failure and can cause death AIDS occurs in the late stage of HIV infection, which will cause the complete breakdown of the body's immune system AIDS is regarded as a life-threatening sexually transmitted disease, which can be transmitted through physical contact, blood transfusion, sharing needles and other ways If diagnosed at a later stage, the survival rate is almost zero AIDS related immune system symptoms range from mild colds and fever to more severe pneumonia and cancer Anaphylaxis: anaphylaxis can be defined as a severe immune system response to normal harmless substances Pollen, fungal spores, latex rubber, peanut and other foods, as well as penicillin and other drugs can cause allergic reactions Sometimes, it is caused by a variety of allergic reasons Although allergic symptoms are often minor consequences, it is still recommended to see a doctor to identify potential problems Allergy: This is a serious and extreme form of allergic reaction It can induce a series of physical discomfort symptoms by food, medicine, mosquito bites and other allergens Pruritus, sore throat and low blood pressure are some of the common symptoms of allergies If not diagnosed and treated in time, allergies can be life-threatening Asthma: This is a chronic lung disease caused by inflammation of the airway Allergens, irritants and even physical activities may induce inflammation and cause discomfort Asthma symptoms include wheezing, coughing, shortness of breath and chest tightness Autoimmune disease: This is a group of diseases of the immune system, involving cells of the immune system misinterpreting signals and starting to attack their own cells Autoimmune diseases can bring serious health risks to patients Ch é diak Higashi syndrome: This is a rare autosomal recessive genetic disease caused by mutations in lysosomal transport regulating genes This syndrome affects all major organs of the body and stops their function It damages cells in the immune system and makes them lose their ability to fight microbes and other invaders People with this disease will be repeatedly infected Bone marrow transplantation is the most effective way to treat the disease If the condition is not serious, the immune system can be strengthened by vitamin supplement Common variant immunodeficiency: this disease occurs when the body has a small number of antibodies The most common variant immunodeficiency is in adults Sometimes it can be seen in newborns, but the symptoms don't show until they are over 20 Symptoms include non bacterial infections of the ears, sinuses, bronchi, and lungs In addition, swelling and pain of joints, ankles, elbows or wrists are also common symptoms Some patients also report enlarged lymph nodes or spleen Pollen fever: similar to allergic reactions and caused by airborne substances such as pollen, fungal spores, and even animal dander It is also known as allergic rhinitis Symptoms include runny nose, tears and sneezing, which are similar to those of a cold Urticaria: This is an outbreak of skin disease that responds to allergens Allergens are foods or contact with specific foods Skin response to allergens can lead to itchy blisters In addition, urticaria can induce other symptoms such as swelling of the lips, tongue and face Human T lymphocytic leukemia virus (HTLV): it can seriously affect the human immune system This immune system disease is prevalent among drug users with multiple sexual partners People with genital ulcers and syphilis are more likely to develop human T-lymphocytic leukemia virus HTLV is transmitted through sexual contact, blood transfusion or pregnancy High IgE syndrome: the symptom of this disease is repeated staphylococcal infection with eczema like rash High IgE syndrome is a hereditary disease, which can be classified as dominant or recessive There are two sets of patients with dominant high IgE syndrome who can't lose their primary teeth High IgM syndrome: This is a rare immune deficiency disease It is difficult for the patient's immune system to produce both IgA and IgG antibodies The cause of the disease is a genetic defect in T cells Because of this defect, B cells can not get the signal to produce IgA and IgG antibodies, so they will continue to produce IgM antibodies Primary immunodeficiency: This is a series of immune system diseases caused by gene abnormality Patients are born with immune system defects, the same symptoms and effects as AIDS, but different from AIDS, it does not need to be acquired Selective IgA deficiency: a specific immune deficiency in which the immune system is unable to produce IgA antibodies These antibodies protect the body against oral and digestive tract infections Obviously, without them, the body is prone to multiple mucosal infections Skin allergy: skin allergy is similar to other allergic reactions except for the immune response expressed through the skin Skin allergy is an acute response of the immune system to certain harmless substances Skin allergies are characterized by itching, blisters and redness X-linked agammaglobulinemia: a genetic disease in which the body's ability to resist infection is limited If the immune system can't produce enough antibodies to resist infection, the body will naturally have a wide range of infections Listed above are some of the major immune system diseases In addition, there are many genetic and acquired immunodeficiency As the immune system protects us from infection and disease, it is necessary to find ways to strengthen it.
