Figure 1. Early Symptoms of HIV. The stages of HIV infection are acute infection (also known as primary infection), latency, and AIDS. Acute infection lasts for several weeks and may include symptoms such as fever, swollen lymph nodes, inflammation of the throat, rash, muscle pain, malaise, and mouth and esophageal sores. The latency stage ...
Main symptoms of AIDS. Acquired immunodeficiency syndrome (AIDS) is defined as an HIV infection with either a CD4 + T cell count below 200 cells per μL or the occurrence of specific diseases associated with HIV infection. [32] In the absence of specific treatment, around half of people infected with HIV develop AIDS within ten years. [32]
Severe Combined Immune Deficiency; Other names: Alymphocytosis, Glanzmann–Riniker syndrome, Severe mixed immunodeficiency syndrome, and Thymic alymphoplasia [1] David Vetter, a child born in 1971 with severe combined immunodeficiency (SCID). Specialty: Immunology Treatment: Bone marrow transplantation and prophylaxis against infection: Medication
The human immunodeficiency viruses (HIV) are two species of Lentivirus (a subgroup of retrovirus) that infect humans. Over time, they cause acquired immunodeficiency syndrome (AIDS), [ 1 ] [ 2 ] a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. [ 3 ]
Humoral immune deficiency (including B cell deficiency or dysfunction), with signs or symptoms depending on the cause, but generally include signs of hypogammaglobulinemia (decrease of one or more types of antibodies) with presentations including repeated mild respiratory infections, and/or agammaglobulinemia (lack of all or most antibody production) which results in frequent severe infections ...
The precise symptoms of a primary immunodeficiency depend on the type of defect. Generally, the symptoms and signs that lead to the diagnosis of an immunodeficiency include recurrent or persistent infections or developmental delay as a result of infection. Particular organ problems (e.g. diseases involving the skin, heart, facial development ...
Clinical manifestations of combined immunodeficiencies vary greatly, ranging from diarrhea and sinus infections to opportunistic infections caused by mycobacteria, fungi, and vaccination reactions resulting in localized to systemic symptoms. [1] Antibiotics and immunoglobulin replacement therapy are typically administered to patients as needed.
Severe combined immunodeficiency (SCID) DiGeorge syndrome; Hyperimmunoglobulin E syndrome (also known as Job's Syndrome) Common variable immunodeficiency (CVID): B cell levels are normal in circulation but with decreased production of IgG throughout the years, so it is the only primary immune disorder that presents onset in the late teens years.
