Transcript CUTANEOUS MANIFASTATIONS OF HIV/AIDS

Cutaneous manifestation of HIV
infection and AIDS
Deepa v saka
INTRODUCTION
• Cutaneous manifestations are first amongst the clinical features of
AIDS.
• Seen at every stage of HIV infection.
• 90% of HIV infected patients develop skin manifestations.
• Act as markers & reflect underlying immune status.
• HIV predisposes patients to numerous opportunistic infections,
malignancies, and neurologic disease.
PATHOGENESIS
Primary inf. ( Fever, joint pain, night sweats)
Viral replication in lymphoid organs
Continuous stimulation of immune response
Exhaustion of immune response
Destruction of lymphoid tissue
Impairment of immune response to new pathogens
Epidermal langerhans cells become infected by HIV, decreasing their
function

REITER’S SYNDROME
• Triad of Non Gonococcal Urethritis + Conjuntivitis + Arthritis.
• An episode of peripheral arthritis of >1 month duration along with
urethritis & cervicitis.
• Increased incidence of both Reiter’s syndrome and psoriasis in HIV
infection.
• Treatment: Acitretin
Zidovudine
Infliximab
PSORIASIS
• In HIV, immune dysregulation could be a triggering factor in genetical
predisposed.
• Recurrent infection like staphyloccocal or candidiasis exacerbates
psoriasis in HIV.
• Psoriasis in HIV manifests in two clinical forms:
- A benign form with guttate or lagre plaque type lesions
- A diffuse form or psorisiform dermatitis comprising palmoplantar
keratoderma that -> generalised
• Treatment: Antiinflammatory agents
Systemic retinoids
Phototherapy
CONCLUSION
• Dermatologic disease is extremely common & varied in HIVinfected patients.
• HIV-infected individuals: Increased prevalence or severity, atypical
presentations, or difficulty with treatment of disease.
• Dermatological manifestation may be the first clue of HIV
infection.
• Offering HIV testing to affected individuals can lead to early
diagnosis & treatment of HIV infection and, ideally, a decrease in
disease progression & transmission.
