Case Report: Suspicion for Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) has a varied and progressive clinical course. Although occasionally initial presentation is as straightforward as lupus nephritis, often it is a complex picture involving multiple vague symptoms ranging from arthritis to psychosis. A clinician must have a high index of suspicion for diagnosis, versed on the symptoms, criteria for diagnosis and clinical patterns.
This case is important because, as demonstrated by our patient, SLE is an evolving disease and recognizing the varied symptomotology and the differential diagnosis in regards to these patients can lead to sooner diagnosis and mitigation of long term organ dysfunction and failure. There should be a high clinical suspicion in patients presenting with such vague and varied symptoms.
Literature review using PubMed/Ovid MEDLINE with searches for “systemic lupus erythematosus,” “heart AND systemic lupus erythematosus,” limited to English language, all age child, and latest 10 years

Differential Diagnosis
• SLE is the most common rheumatic disease associated with significant morbidity and mortality in children
• Recognize that a positive ANA occurs in many conditions other than SLE and even in healthy individuals
• Diagnosis is based upon having 4 of the 11 clinical criteria and laboratory evaluation
• Recognize the significance of multi-organ involvement in SLE• Know that SLE can evolve in presentation with differing manifestations each time

Clinically, Patient A had 3 of 11 criteria for diagnosis of lupus: pericardial effusion, +ANA/ +smooth muscle antibody, and thrombocytopenia. She currently continues to be followed for further progression of her neurologic complications, development of skin manifestations, progression of possible renal disease or other clinical symptoms and/or criteria that would confirm a diagnosis of SLE. All cardiac medications have since been discontinued.

Organ System Symptom
Musculoskeletal Arthritis, arthralgia
Constitutional Fever (absence of infection), fatigue, weight loss
Skin Malar (butterfly) rash, alopecia, photosensitivity, purpura, Raynaud’s phenomenon, urticaria, vasculitis
Gastrointestinal Nausea, vomiting, abdominal pain
Renal Proteinuria, hematuria, nephrotic syndrome
Hematologic Anemia, thrombocytopenia, leukopenia
Cardiac Pericarditis, endocarditis, myocarditis
Neurologic Seizures, psychosis, peripheral and cranial neuropathies
Pulmonary Pulmonary hypertension, pleurisy, parenchymal disease
1. Malar rash Fixed erythema, flat or raised, over the malar eminences
2. Discoid rash Erythematous raised patches with adherent keratotic scaling and follicular plugging; atrophic scarring may occur
3. Photosensitivity Exposure to UV light causes rash
4. Oral ulcers Includes oral and nasopharyngeal, observed by physician
5. Arthritis Nonerosive arthritis involving 2 or more peripheral joints, characterized by tenderness, swelling, or effusion
6. Serositis Pleuritis or pericarditis documented by EKG, rub, or evidence of pericardial effusion
7. Renal Proteinuria >0.5 g/d, >3+, or cellular casts
8. Neurologic Seizures without other causes or psychosis without other cause
9. Hematologic Hemolytic anemia, leukopenia, lymphopenia, or thrombocytopenia in the absence of offending drugs
10. Immunologic Anti-dsDNA, anti-Sm, anti-phospholipid
11. Antinuclear antibodies
An abnormal titer of ANAs by immunofluorescence or an equivalent assay at any point in time in the absence of drugs known to induce ANAs
If 4 of these criteria are present at any time curing the course of disease, a diagnosis of systemic lupus can be made with 98% specificity and 97% sensitivity.
Lab Test Description
ANA •Sensitive but not specific•JIA, dermatomyositis, scleroderma, thyroid disease
Anti-dsDNA •More specific for SLE•Monitors disease activity•Present in high titers during active disease
Anti-Smith •Most specific for SLE
Anti-ribosomal P •Found in higher percentage with psychosis
