Systemic Lupus
Erythematosus
Iris Zink, CRNP
Objectives
Discuss pathophysiology of SLE and its
various presentations
 Discuss impact of SLE on patient’s
health
 Discuss the criteria for diagnosis of
SLE, and interpretation of lab tests
 Discuss the interventions and standard
therapies for treatment of SLE

The Great Imitator
SLE: Definition
Lupus is a systemic autoimmune disease in which
the body loses tolerance to self:
•Can affect virtually any organ in the body and initial
symptoms are often nonspecific, making it very difficult to
diagnose
•Most commonly seen in women of childbearing age but 10%
of patients are men
•Average time of two years from onset of symptoms to
diagnosis
(Cevera, Medicine, 1993; Font, Semin Arthritis Rheum, 2004)

SLE Prevalence
 Prevalence:
40-50 cases per 100,000
people
 Approximately 750,000 cases in U.S.
today
 Much more common in developed
countries and in urban areas
 15-20% diagnosed during childhood
(Schur, Epidemology and pathogenesis of SLE. Up to date v. 14.2; Petri. SLE. Current
Rheumatology, Chapter 19)
Epidemiology: Race, Gender
and Age

More prevalent in African Americans,
Caribbean populations, Hispanics and
Asians

Female > Male

Most common between 20-40 year olds
How is SLE diagnosed?
 Labs
 Symptomatology
 Patients
must meet 4/11 criteria
1.Malar Rash
2.Discoid Rash
3. Photosensitivity
4.Mucocutaneous Ulcers
5. Arthritis
6. Serositis
7. Renal Disorder
8. Neurologic Disorder
Neuropsychiatric
Systemic Lupus Erythematosus (NPSLE)
(95 vs 80%)
CNS (diffuse & central)

Acute confusional state
 Psychosis
 Anxiety
 Depressive disorders
 Cognitive dysfunction *
 Seizures
 CVA
 Chorea
 Myelopathy
 Demyelinating syndrome
 Headaches *

 Scl-70
 Antiphospholipid

Symptoms
•
Fever and fatigue 42%
•
Alopecia 18%
•
Lupus Nephritis 40-60%
Causes of Death

Death from renal disease is most common in
first 3-5 years
 Patients who survive the first 5 years of
disease die from CVD at a much younger age
than disease free individuals
 Women with SLE ages 35-44 have MI’s 50
times that of age matched controls
Quality of Life




Significantly worse QOL vs.
– age matched controls
– HTN, diabetes, or MI
Lupus lower than patients with CHF

Summary
Due to variety of symptoms, must know
entire history
 Great imposter
 Refer to Rheumatology if SLE
suspected
 In SLE watch closely as things change
fast and CVD is a real concern
 Monitor for QOL issues
