Extranodal involvement is common in lymphomas associated with human immunodeficiency virus infection (HIV) and acquired immunodeficiency syndrome (AIDS). However, primary pulmonary AIDS-related non-Hodgkin’s lymphoma is very rare and only few reports were published in the medical literature. Clinical presentation is nonspecific, with “B” and respiratory symptoms. Also, patients were with advanc...

To assess the influence of HLA on AIDS-free survival, human immunodeficiency virus load, and CD4 cell counts, 91 Caucasian and 48 African-American seroprevalent men were typed for HLA classes I and II and TAP alleles. HLA associations with these markers were assessed by assigning sum integer scores based on 7 class I allele-TAP variants (+1) and 13 class I-class II-TAP combinations (-1) with di...

The hypothesis is presented that a human T-cell leukemia virus (HTLV) or a related agent produces a lytic response of T cells manifested by the acquired immune deficiency syndrome (AIDS) and a proliferative response represented by the adult leukemia/lymphoma (ATL) syndromes. The sequence or cascade of T-cell events following loss of T4 helper cells in AIDS includes reactivation of Epstein-Barr ...

Human immunodeficiency virus (HIV) causes a chronic infection beginning in most individuals with an acute syndrome followed by an asymptomatic stage and progresses in untreated adults over a median of 10 years to the late stage called AIDS. The virus rapidly and enormously replicates from the initiation of infection. The principal immunodeficiency caused by HIV is depletion in the subset of T l...

In the past decade, evidence has accumulated that human immunodeficiency virus (HIV)-induced chronic immune activation drives progression to AIDS. Studies among different monkey species have shown that the difference between pathological and non-pathological infection is determined by the response of the immune system to the virus, rather than its cytopathicity. Here we review the current under...

AIDS was first recognized among Africans in late 1982 in male and female patients either resident in or referred to Belgium for care (1-3). As of September 1985, 157 cases of AIDS among people originating from 22 African countries (63% from Zaire and 10% from the Congo) were diagnosed in eight European countries, mainly Belgium, France and Switzerland. These persons represented 10% of the 1,573...

The Human Immunodeficiency Virus (HIV) is one of the most threatening viral agents. This virus infects approximately 33 million people, many of whom are unaware of their status because, except for flu-like symptoms right at the beginning of the infection during the acute phase, the disease progresses more or less symptom-free for 5 to 10 years. During this asymptomatic phase, the virus slowly d...

Acquired immunodeficiency syndrome (AIDS) is a spectrum of conditions caused by infection with the human virus (HIV). Among people AIDS, cases COVID-19 have been reported in many countries. (coronavirus disease 2019) severe acute respiratory coronavirus 2 (SARS-CoV-2). In this manuscript, we are going to present within-host COVID-19/AIDS coinfection model study dynamics and influence between AI...

A human retrovirus--human T cell lymphotropic virus-III (HTLV-III)--has recently emerged as the probable cause of acquired immunodeficiency syndrome (AIDS). In May 1984, 250 outpatients at a hospital in a remote area of eastern Zaire were surveyed for AIDS type illnesses and the prevalence of antibodies against HTLV-III determined by an enzyme linked immunosorbent assay using disrupted whole HT...

BACKGROUND: The Acquired Immunodeficiency Syndrome (AIDS) constitutes a sub-epidemic in Brazil. Due to the increasing number of women infected by the virus, the vertical transmission increased substantially, and due to the lack of adequate prophylactic treatment, many children are infected and show manifestations of the disease in early ages. Multiple systems are affected by the HIV virus, and ...
