Q

HOW can a person who is HIV+ avoid getting an opportunistic infx?

A
  • Take ART EVERY DAY (prn/prescribed)
  • Goal:
    • NON-detectable lvls
    • Maint CD4 count so immune system can function

Q

Opportunistic CNS Infxs

Explain how we get them there…

A
  • Blood/brain barrier (BBB) usually prevents entry of infectious material
  • HIV is able to cross BBB**
    • maybe on its own, maybe in infected macrophages and T-cells
  • Even in a normal immune system→ LESS immune protection in CNS vs rest of body:
    • NO lymphatic system
    • LOWER antibody lvls
    • FEWER WBCs

Q

Long term survivors of HIV aka People Living w/ HIV (PLHIV)

this is common

A

Chronic pain

69
Q

Chronic Pain in PLHIV

A
  • Prev→ 39-55%
    • HIGHER + higher severity of pain in indigent population
  • Concurrent psychiatric illness→ 40% more likely pain
  • Concurrent subs abuse→ higher pain severity and disruption daily function
70
Q

Multifactorial Etiology of Chronic Pain in PLHIV:

A
  • Direct effects of HIV infx
  • Chronic inflamm and immune activation
  • SEs of ART drugs/other drugs
  • Neuro mechs
  • Comorbs/Multimorbs
  • Opportunistic infx’s***
  • Aging/frailty
  • Psychosocial influences
  • Rx opiods misuse/heroin use
  • Gender/ethnic diffs→ perception/expression of pain
71
