Human immunodeficiency virus [HIV] disease B20- >
acquired immune deficiency syndrome [AIDS]
AIDS-related complex [ARC]
HIV infection, symptomatic
A disease caused by human immunodeficiency virus
(hiv). People with acquired immunodeficiency syndrome
are at an increased risk for developing certain cancers
and for infections that usually occur only in individuals
with a weak immune system.
A prodromal phase of infection with the human
immunodeficiency virus (hiv). Laboratory criteria separating
aids-related complex (arc) from aids include elevated or
hyperactive b-cell humoral immune responses, compared to
depressed or normal antibody reactivity in aids; follicular
or mixed hyperplasia in arc lymph nodes, leading to lymphocyte
degeneration and depletion more typical of aids; evolving
succession of histopathological lesions such as localization
of kaposi's sarcoma, signaling the transition to the
A syndrome resulting from the acquired deficiency of cellular
immunity caused by the human immunodeficiency virus (hiv). It
is characterized by the reduction of the helper t-lymphocytes
in the peripheral blood and the lymph nodes. Symptoms include
generalized lymphadenopathy, fever, weight loss, and chronic
diarrhea. Patients with aids are especially susceptible to
opportunistic infections (usually pneumocystis carinii pneumonia,
cytomegalovirus (cmv) infections, tuberculosis, candida infections,
and cryptococcosis), and the development of malignant neoplasms
(usually non-hodgkin's lymphoma and kaposi's sarcoma). The human
immunodeficiency virus is transmitted through sexual contact,
sharing of contaminated needles, or transfusion of contaminated blood.
An acquired defect of cellular immunity associated with infection
by the human immunodeficiency virus (hiv), a cd4-positive t-lymphocyte
count under 200 cells/microliter or less than 14% of total lymphocytes,
and increased susceptibility to opportunistic infections and malignant
neoplasms. Clinical manifestations also include emaciation (wasting)
and dementia. These elements reflect criteria for aids as defined
by the cdc in 1993.
An infection caused by the human immunodeficiency virus.
Any state of infection accompanied by evidence of hiv in the body
(positive test for hiv genome, cdna, proteins, antigens, or antibodies);
may be medically asymptomatic or symptomatic; use aids when appropriate.
Includes the spectrum of human immunodeficiency virus infections that
range from asymptomatic seropositivity, thru aids-related complex
(arc), to acquired immunodeficiency syndrome (aids).
One or more indicator diseases, depending on laboratory evidence of
hiv infection (cdc); late phase of hiv infection characterized by
marked suppression of immune function resulting in opportunistic
infections, neoplasms, and other systemic symptoms (niaid).
