Q

Describe the subacute lesions seen in lupus?

A

typically symmetric, widespread, superficial, nonscarring
Seen most often in sun-exposed areas

Involves erythematous annular or polycyclic plaques with scaling (psoriasiform)
In sun-exposed areas, is possibility of smaller plaques and papules
Progresses to internal disease in 10%–15% of patients
Is strongly associated with anti-Ro antibodies (60%–100%)
Is associated with HLA-A1, B8, DR3
Can be triggered by drugs (HCTZ, Terbinafine, Griseofulvin, ACE inhibitors, calcium channel blockers, NSAIDs, Etanercept, Thalidomide, antihistamines)
NO SCARRING

Q

Describe the discoid (chronic) lesions:

A

Seen typically on face, scalp, pinnae, behind ears, neck
Seen in non–sun-exposed areas
Can exist as part of systemic disease or in isolation
Presents central atrophic scarring with active indurated erythema at periphery
Can involve irreversible alopecia from follicular destruction
Does not go away and is SCARRING

A

Acute and Subacute

Rarely chronic lesions

20
Q

What are some other mucocutaneous conditions seen with lupus?

A

Alopecia:
Can be diffuse or patchy
Can be reversible or permanently scarring due to discoid lesions
Mucosal lesions:
Can affect the mouth, nose, anogenital area
Are typically painless, but may not be
Can involve painful ulcerations if central depression occurs
Vasculitis:
May manifest as:
Urticaria
Palpable purpura
Nailfold or digital ulcerations
Erythematous papules of pulps of fingers or palms, splinter hemorrhages

21

A 
Musculoskeletal (painful joints)
Kidneys
Neurological
Cardiovascular
Pleura and Lungs
23
Q

What is the most frequent cardiac complication from lupus?

Duration can be hours or days.

24
Q

What are the pulmonary manifestations seen with lupus?

A 
Pneumonitis
pulmonary hemorrhage
pulmonary hypertension
shrinking lung syndrome
Acute lupus pneumonitis:
Pleuritic chest pain, cough with hemoptysis and dyspnea when infection ruled out
25
Q

What are some nervous system manifestations with lupus?

A

Psychiatric
Mood disorders, anxiety, psychosis
Cognitive
Attention deficit, lack of concentration, impaired memory or word finding issues

Neurologic
Acute confusional state, disturbance in consciousness or level of arousal

26
Q

What eye conditions occur with lupus?

A 
Visual defects
ptosis
nystagmus
vertigo
peripheral neuropathy of motor and sensory function
27
Q

What is the most important treatment in lupus?

A

SUNBLOCK

Sunburns activate lupus

28
Q

What is the #1 medication for treatment in lupus?

A

Plaquenil (hydroxychloroquine)

used for skin and joint manifestations.

29
Q

What is toxicity concern with the use of plaquenil?

A

Retinal toxicity
Must see ophthalmologist first before beginning this medicine and then again at 6 months, 1 year and then yearly follow ups (looking for plaque deposits on the retina).

30
Q

What do the corticosteroids target with lupus treatment?

A

Use topical and oral steroids with lupus
Topical uses
Skin rashes, except on face
Systemic uses
Low dose for skin rashes and joint involvement
Moderate dose combats aggressive skin disease, serositis, and hematologic abnormalities
High dose for nephritis, cerebritis, vasculitis, and life threatening hematologic abnormalities

31
Q

Why are immunosuppressants used in treatment of lupus

A

Because they are steroid sparing

32
Q

Which immunosuppressants are used?

A 
Shown to improve outcomes for severe lupus
Are superior to steroids alone
Include: 
Methotrexate
Cellcept (mycophenolate mofetil)
