What is the pathogenesis of acquired immunodeficiency syndrome?

Answer]: B Acquired immunodeficiency syndrome is caused by human immunodeficiency disease suffocation infection, the virus belongs to the lentivirus of the family Chunmin retrovirusidae, the cylindrical core of the virion body is two positive polarity single-stranded RNA linked by hydrogen bonds at the 5-terminus, carrying RNA reverse transcriptase, nucleocapsid protein P24, is an RNA virus.

Answer: Friend] :d

Patients with acquired immunodeficiency syndrome often have the following clinical manifestations: recent (3-6 months) weight loss of more than 10 and persistent fever for more than 38 1 months. Weight loss of more than 10 in the recent period (3 to 6 months) and persistent diarrhea (up to 3 to 5 times a day) for more than 1 month.

Pneumocystis carinii pneumonia (PCR). Kaposi's sarcoma. Myojin sues Yinxian of fungal or other conditions that cause the infection.

Test site: Diagnosis of Acquired Immune Deficit Syndrome.

Answer]: CAIDS is a fatal infectious disease caused by HIV-infected infection and characterized by damage to the systemic immune system. The primary HIV-infected cells are macrophages, which are subdominantly infected with CD4 <>

T cells are dissolved and destroyed, resulting in a progressive decrease in the number of T cells and loss of function of coeloma, resulting in severe immune deficiencies and opportunistic infection of a variety of pathogens.

Answer]: B Analysis: The factors that induce acquired immunodeficiency include non-infectious factors and infectious factors, and non-infectious factors include:

Malnutrition (selected by D), malignant tumors, iatrogenic immunodeficiency (long-term heavy use of immunosuppressants such as hormones and antineoplastic drugs (option E), or radiation injury (option C), etc.); Infectious factors include certain viruses, bacteria (option A), and parasitic infections, all of which can affect the immune system to varying degrees, resulting in acquired immunodeficiency. Side-leakage.

Immune deficiency can be divided into () cell defects and B cell defects according to the cause and mechanism of the disease.

b.Complement deficiency, phagocytic cell defect.

c.Combined immunodeficiency, complement intrinsic component defects.

d.Primary immunodeficiency, secondary immunodeficiency.

Correct answer: Primary immunodeficiency, secondary immunodeficiency.

Traveler Answer] :d

The clinical manifestations of primary immunodeficiency diseases are extremely complex due to the differences in **, but their common manifestations are very consistent, i.e., recurrent infections, susceptibility to tumors, and autoimmune diseases. Most primary immunodeficiency disorders have a significant family history.

Answer]: B Analysis: Primary immunodeficiency diseases have different clinical manifestations due to different immune function and lead deficiency.

The common clinical features are: susceptibility to infection is significantly increased, and repeated infection is the biggest characteristic of the disease. It is prone to malignant tumors, and some immunodeficiency diseases are prone to autoimmune diseases.

The clinical manifestations and pathological lesions are varied. Deficiencies in the immune system of different components can cause different diseases; Patients with the same immunodeficiency disorder may also present differently. Therefore, the correct answer is b.
