What is the pathogenesis for HIV?
The pathogenesis of HIV is basically a struggle between HIV replication and the immune responses of the patient, via cell-mediated and immune-mediated reactions. The HIV viral burden directly and indirectly mediates CD4+ T-cell destruction.
Does HIV cause rheumatoid arthritis?
HIV can raise your arthritis risk: People with HIV may be more likely to get painful types of arthritis, like reactive arthritis, gout, rheumatoid arthritis, or psoriatic arthritis, with chronic, or long-lasting, inflammation.
What is the pathogenesis of the immunosuppression caused by HIV?
Immunosuppression due to HIV infection is a resultant of several factors including defective innate signaling pathways, increased viral replication and virus load, gradual loss of peripheral CD4+T cells and depletion of T lymphocytes at mucosal sites that collectively lead to progressive immune deficiency and AIDS …
How does HIV cause a latent infection?
Latently infected cells are rare in vivo and appear to arise when activated CD4+ T cells, the major targets cells for HIV-1, become infected and survive long enough to revert back to a resting memory state, which is nonpermissive for viral gene expression.
What is the meaning of pathogenesis?
Pathogenesis: The development of a disease and the chain of events leading to that disease.
What STD causes rheumatoid arthritis?
Gonococcal arthritis is a rare complication of the sexually transmitted infection (STI) gonorrhea. It generally causes painful inflammation of the joints and tissues. The arthritis tends to affect women more than it affects men.
Which of the following viruses are known for causing latent infections?
Many viruses have a propensity to cause latent infections. The majority of these viruses are from the family of Herpesviridae: herpes simplex virus (HSV)-1, HSV-2, varicella zoster virus (VZV), Epstein–Barr virus (EBV), CMV, human herpesvirus (HHV)-6, HHV-7 and Kaposi’s sarcoma-associated herpesvirus (KSHV/HHV)-8.
What is pathogenesis of virus?
Viral pathogenesis is the study of the process and mechanisms by which viruses cause diseases in their target hosts, often at the cellular or molecular level. It is a specialized field of study in virology. Pathogenesis is a qualitative description of the process by which an initial infection causes disease.
What is the pathogenesis of Covid 19?
The pathological result of SARS and COVID-19 is diffuse alveolar damage with fibrin rich hyaline membranes and a few multinucleated giant cells [17, 18]. The aberrant wound healing may lead to more severe scarring and fibrosis than other forms of ARDS.
Who is the author of the pathogenesis of Ra?
Author: Howard R Smith, MD; Chief Editor: Herbert S Diamond, MD more… The pathogenesis of RA is not completely understood.
Where does the pathogenesis of HIV take place?
Human immunodeficiency virus (HIV) pathogenesis has proven to be quite complex and dynamic with most of the critical events (e.g., transmission, CD4+T-cell destruction) occurring in mucosal tissues.
What are the causes of rheumatoid arthritis ( RA )?
The pathogenesis of RA is not completely understood. An external trigger (eg, cigarette smoking, infection, or trauma) that sets off an autoimmune reaction, leading to synovial hypertrophy and chronic joint inflammation along with the potential for extra-articular manifestations, is theorized to occur in genetically susceptible individuals.
What are the steps in the infection of HIV?
The steps occurring in infection involve an interaction of HIV not only with the CD4 molecule on cells but also with other cellular receptors recently identified. Virus-cell fusion and HIV entry subsequently take place.
