Presentation to Family Physician
Genevieve has visited walk-in clinics a couple times in the past year with complaints of headaches, myalgia, joint pain, and fatigue.◦ No infections or signs of disease were found in routine physical◦ Doctors recommended maintaining a healthy lifestyle and taking
NSAIDs for pain.◦ Following advice of one physician, Genevieve began recording
information about symptom onset, duration, and nature to show her family doctor.
She observed the following:◦ Photosensitivity resulting in frequent sunburns on face and shoulders◦ Symptoms experienced every 1-2 months for about 1-2 weeks. In
between, she feels slightly tired and has some aches, but is otherwise normal.
◦ This is the first time she has experienced chest pain.
Medical History
Otherwise, has no history of significant illness or injury and has had no recent infections.
Maintains a healthy weight, follows guidelines for healthy eating, and enjoys playing tennis in spare time.
Non-smoker and moderate drinker
Not taking any medications (with exception of occasional OTC painkillers) or oral contraceptives
Medical History (Continued)
Completing her Masters degree in linguistics at University of Toronto and is living with two friends in an apartment
She has been in a monogamous relationship for one year.
Has had significant sources of stress throughout university years: abusive ex-boyfriend and death of close friend, in addition to typical student anxieties
Grew up in suburbia and is the eldest of four healthy children
Family medical history is unremarkable – all parents and grandparents are still living and in good health
Personal History
Temperature: 100.1° F
Heart rate: 82 beats per minute
Blood Pressure: 112/70 mmHg
Rate of Respiration: 20 breaths/minute
Physical Examination: Vital Signs
Two painless oral ulcers found on wall of left cheek
Chest pain became worse when breathing deeply or lying down; improved when leaning forward
On auscultation of chest, physician heard a friction rub.
Joint stiffness and slight swelling noted in wrists and knees - range of motion is slightly decreased
Swollen ankles and feet
Physical Examination
The physician decides to run a battery of tests, with emphasis on diagnosing a cardiac issue.◦ Electrocardiogram◦ Echocardiograph◦ Complete blood count◦ Autoantibody testing◦ Urine analysis◦ Chemistry profile◦ Thyroid panel◦ Erythrocyte sedimentation rate
The Test Battery
Results from Electrocardiogram and Echocardiograph
Echocardiograph
Normal Electrocardiograph shown above. Genevieve’s showed:
ST segment elevations (upwardly concave)Depression of PQ segment
Based on interpretation of electrocardiogram and echocardiograph, the cardiologist determines pericarditis in the patient. There is some pericardial effusion, but it is minimal.
What should be done, now that the cardiac problem is diagnosed?
Does pericarditis adequately explain all symptoms?
Cardiac Diagnosis: Pericarditis

Erythrocyte Sedimentation Rate:
Normal = up to 20 mm/hr
Genevieve’s = 210 mm/hr
Chemistry Profile, Urinalysis, Thyroid Panel, and Autoantibody Tests
Results from chemistry profile, urinalysis, and thyroid panel were all within normal range.
Autoantibody Test Results
Antibody Normal Result
Genevieve’s Result
Anti-nuclear Positive or Negative
Positive
Anti-Sm Negative Positive
Anti-double stranded DNA
Negative Positive (high)
Anti-SSA Negative Negative
Anti-SSB Negative Negative
These results implicate that Genevieve’s disease falls under a certain group of disorders.
What group is this?
Based on her collective symptoms and test results as well as epidemiological data, a certain disease is highly suspect.
Diagnosis?
This rash is found below Genevieve’s neck.
A definitive diagnosis can be made.
On her next appointment...
Incurable auto-immune disease that primarily affects women. Non-Caucasian women are at significantly higher risk.
There are three types: Systemic Lupus Erythematosus, Discoid Lupus, and Drug Induced Lupus.
Cause is unknown. Studies have loosely implicated genetics, hormones, stress, and environment to disease development.
Can manifest with an extremely wide variety of symptoms in almost every system of the body (kidneys, heart, lungs, skin, nervous system, blood, joints, and muscles can all be affected).
Not everyone experiences all symptoms; every case is very different.
Michael Jackson reportedly had it!
A little bit about Lupus...
NSAIDs and/or analgesics
Anti-malarials (Hydroxychloroquine)
Immunosuppressives (chemotherapy or anti-rejection agents)
Glucocorticoids (usually Prednisone)
Avoid direct sunlight
Eat a wholesome diet – preliminary studies have shown that becoming vegetarian (with proper protein and nutrient intake) can significantly help with symptoms
Treatment
Systemic Lupus Erythematosus used to be fatal within five years
Now, the treatment for it is very effective and most people survive many years following diagnosis
In later life, other diseases may be worsened or develop in association to the lupus.
