HIV Dermatology

With immune reconstitution

Some diagnostic categories are disappearing: Kaposi's sarcoma, molluscum, staph folliculitis

Other diagnostic categories are filling the void: Warts, squamous cell carcinoma-in-situ of the anal area

Diseases that were controlled are erupting: Eosinophilic folliculitis, drug reactions to antibiotics

Diseases that were never seen are rearing their heads: Sarcoid, morphea, fat redistribution

The constants: Psoriasis, eczema, photodermatitis, prurigo nodularis, scabies

Kaposi's Sarcoma-making new diagnoses in gay men who are not on HAART

-CD4 count 300 - 700

-initiate HAART and stay on 3-6 months before

-KS on HAART - ? time to

Molluscum

- melts away w/CD4 >100

- recalcitrant warts - LN2 or curretting

- Cidofavir Gel not that promising

Staph Folliculitis/Staph Pyodermas/Ce!luliti-top dermatology diagnosis 1991

-now seen in persons who are not on Septra

Treatment: Dicloxacillin/Keflex

Rifampin for eradication of staph (don't use with PIs)

Bactroban intranasally

Differential for Staph: Helicobacter Cinidiae

Warts

Increased prevalence?

Other diagnoses disappearing?

People living long enough to develop these?

Warts - Treatment

Mouth - laser/surgical ablation + Aldara

Genitals - not as responsive to Aldara LN2 + Podophyllin Caution - Hydroxyurea

Flat Warts - Retin A

Hands/Feet - LN2 Bleamycin DNCB

Pulsed Dye Laser

Genital Squamous Cell Carcinoma-in-situ (Bowen's)

- HPV induced

- ? what is the natural history

- anal pap smears useful in finding dysplastic cells

THEN WHAT?- we don't have treatment to prevent progression to invasive SCC

- identify high risk individuals

- serial biopsies every 3-4 months

- surgical ablation/laser - usually too extensive- Aldara - promising but not always efficacious can cause irritation/infection

- BIG PUBLIC HEALTH QUESTION

Eosinophilic Folliculitis- previously controlled cases flare up

  w/HAART

- before HAART, occurred CDn <200- now occurring within the whole range of CD4 counts

Treatment

Itraconazole 100-400 qd

Elimite qod

UV light

Accutane - caution TGs

Drug Reactions - patients taking Septra/ Clarithromycin for years getting drug rash w/effective HAART treatment

- do not stop HAART treatment- treat through if rash is maculopapular

  - D/C antibiotics first if rash is urticarial/Stevens Johnson

  - with the exception of Nevirapine drug rashes to other HAART drugs very rare

Sarcoid, morphea

- now emerging on HAART treatment

- these are immunologically-based diseases- theory is that you had to be able to mount an immune response

- never saw these diseases before HAART

Fat Redistribution

- buccal atrophy

- zygomatic hypertrophy

- neck size changes

- buffalo humps

- increased abdominal girth

In our cohort

- occurred in 35% of patients- started HAART earlier and were responding better

Treatment:

- liposuction recurrences reported

- fat transfer to cheeks - fat disappears- cheek implants

- continued atrophy makes implants pop through skin-face lifts have been successful

-awaiting drug therapy

Psoriasis

same prevalence but less recalcitrant to treatment

etretinate - oral therapy - now replaced by acetretin - may be more potent -watch triglycerides

Eczema

- continues at same prevalence

- lubrication and mid-potency steroids

- decrease water exposure

Photodermatitis

- persons of color at high risk antibiotics/NSAIDS increase risk- begins in photo distributed areas and then involves non-photo-exposed areas very itchy

- itch can create nodules prurigo nodules + loss of pigment

Treatment

Sunblock

Potent antihistamines

(Doxepin 25mg po qhs)

Potent topical steroids (clobetasol)

Thalidomide

- highly effective

- decreased itch within 1 month

- teratogenic - 2 forms of birth control

- 30% peripheral neuropathy advise baseline nerve conduction exams and monthly neuro questionnaires

- other side effects drowsiness weight gain have not seen drug reactions

- dose: 50 - 100 mg qd

Scabies- Kwell contraindicated in HIV

-  Norwegian scabies =~ Elimite one day + Eurax 6 days. Repeat cycle until
