Systemic Lupus Erythematosus: Follow-up
Updated: Oct 27, 2009
Follow-up
Further Inpatient Care
- Patients with systemic lupus erythematosus (SLE) may require admission for treatment of severe complications, such as lupus nephritis (for pulse steroids, cytotoxic agents) or other entities responsive to high-dose steroids.
- Admit patients with neuropsychiatric presentation or stroke syndromes.
- Admit patients to appropriate service (rheumatology if available) with subspecialty consultations as needed.
Further Outpatient Care
- Conservative management is indicated for the symptomatic relief of arthralgia, arthritis, or myalgia with nonacetylated salicylates, nonsteroidal anti-inflammatory drugs (NSAIDs), or low-dose glucocorticoids.
Inpatient & Outpatient Medications
- Nonacetylated salicylates or NSAIDs may be indicated.
Deterrence/Prevention
- Patients with systemic lupus erythematosus (SLE) should be encouraged to take steps to prevent sunburn by limiting sun exposure, wearing protective clothing, and using sunscreen that protects against both UV-A and UV-B. Exposure to UV light causes SLE to flare in approximately 70% of patients. Sunscreen should have an SPF of at least 15 and should be applied frequently (every 2-3 h) and in the quantity recommended by the manufacturer.

- Patients should have yearly vaccinations for influenza. Pneumococcus vaccine should be updated every 3-6 years.20
- Hepatitis B vaccines are recommended.
- Patients on high-dose immunotherapy should NOT receive live vaccines.
- Although organ involvement requires specific drug therapy, a number of general issues are applicable to every patient with SLE.
- Patients should avoid exposure to direct or reflected sunlight and other sources of UV light. Use sunscreens that block both UV-A and UV-B with sun protection factor (SPF) of 30.
- A conservative approach is to recommend a balanced diet consisting of carbohydrates, proteins, and fats. However, the diet should be modified based on disease activity and response to therapy. Patients with active inflammatory disease and fever may require an increase in caloric intake.
- Glucocorticoids enhance appetite, resulting in potentially significant weight gain. Hunger can be somewhat lessened by the ingestion of water, antacids, proton pump inhibitors, and/or histamine H2 blockers. A low calorie diet should be instituted if significant weight gain occurs.
- Most patients with SLE have low serum levels of 25-hydroxyvitamin D (calcidiol), probably due at least in part to avoidance of sun exposure. Patients with low vitamin D levels should be treated with supplemental vitamin D.
- Patients on long-term glucocorticoids and postmenopausal women should ingest 800 units of vitamin D plus 1500 mg of calcium per day and/or a bisphosphonate to minimize the degree of bone loss.
- Cigarette smoking may increase the risk of developing SLE, and smokers in general have more active disease. Patients should be counseled not to smoke or to quit smoking and be provided with help to do so.
- Inactivity produced by acute illness causes a rapid loss of muscle mass and stamina resulting in a sense of fatigue. This can usually be treated with graded exercise. In selected refractory cases, relief can be obtained with antimalarial drugs.
Complications
- Vasculitis and its various complications (eg, intestinal perforations)
- Pericarditis
- Myocarditis
- Lupus pneumonitis
- Pulmonary hemorrhage, pulmonary hypertension
- Proliferative glomerulonephritis
- Hemolytic anemia, thrombocytopenia
- Intravascular thrombosis (eg, stroke and myocardial infarction)
- Complications of high-dose glucocorticoid therapy
- Complications of cytotoxic agents
- Recurrent spontaneous abortions
Prognosis
- Mortality of those with systemic lupus erythematosus (SLE) has decreased over the past 20 years.23
- Five-year survival rate in Western countries ranges between 93-95%.23
- Mortality typically in the first few years of illness is active disease (eg, CNS, renal, or cardiovascular disease) or infection due to immunosuppression, whereas late deaths are due to atherosclerosis.23,9
Patient Education
- Patients should protect their skin from the sun.
- Compliance with medications and follow-up appointments is important.

Miscellaneous
Medicolegal Pitfalls
- Failure to evaluate for ordinary or opportunistic infections
- Failure to involve a rheumatologist or a primary care provider in the management and disposition of a patient
Special Concerns
- Whether flares of systemic lupus erythematosus (SLE) are more frequent during pregnancy is controversial. The flares do not seem to be exceedingly more serious compared with those in nonpregnant patients. Pregnancy outcomes are generally more likely to be complicated.
- Increased rates of hypertension during pregnancy, premature delivery, unplanned cesarean delivery, postpartum hemorrhage, and maternal venous thromboembolism are all more frequent in women with SLE than in others.
- Fetal growth restriction and neonatal deaths are also frequently seen in association with SLE.
- Predictors for fetal loss include active nephritis at conception and the presence of antiphospholipid (aPL) antibodies.
- High-dose aspirin and NSAIDs should be avoided in the last few weeks of pregnancy.
- Hydroxychloroquine has not been shown to induce congenital malformations. Furthermore, unnecessary discontinuation of hydroxychloroquine during pregnancy may result in lupus flares.
- If indicated, prednisone, prednisolone, and methylprednisolone are the corticosteroids of choice during pregnancy because of their minimal placental transfer.
