Adult and paediatric AIDS patients lacking HIV antibodies detected by enzyme immunoassay in central Africa: further serological studies

Abstract

We describe HIV antigen and HIV-1, HIV-2 and human T-cell leukaemia virus type I (HTLV-I) Western blot (WB) results in 20 adults and 12 children with AIDS who were shown to be HIV-1 seronegative by two commercial enzyme immunoassays (EIA), in Kigali, Rwanda, central Africa. These patients represented 3% of adults and 7.4% of children with AIDS observed in Kigali during the study period. Thirteen of the adults and five of the children were HIV-1 WB positive. All patients were HTLV-I WB negative. One adult AIDS patient had a reactive HIV-2 WB; he is the first HIV-2-infected individual to be diagnosed in Rwanda. HIV antigenaemia was demonstrated in only one adult and one child, suggesting that HIV antigenaemia is not frequent in African AIDS patients, even in the case of weak immunologic responses to HIV core proteins. Three adults and four children had none of the serological markers detected. This study showed that HIV EIA negativity occurs infrequently in African patients with AIDS. In such a situation, an attempt to detect HIV antibodies by a more sensitive technique, such as WB, is necessary.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
