Overview

Common complications of systemic lupus erythematosus include dermatitis, nephritis and arthritis. Prognosis is generally poor, and the 10-year mortality rate of patients with systemic lupus erythematosus is approximately 40%. The disease course can be divided into 4 subcategories based on the course of the disease: developmental phase, preclinical phase, clinical phase, and comorbid complication phase.

Natural History

Systemic lupus erythematosus (SLE) is an autoimmune disease. SLE is a disease of waxing and waning, with possible flare up episodes. SLE usually develops in the second and third decade of life, although it can presents any age, and start with mild symptoms such as fatigue, fever, and skin rashes. Without treatment, the patient will develop symptoms of end organ damage, which will eventually lead to death in most of the patients.

The disease course can be divided into 4 subcategories based on the course of the disease:^[1]^[2]^[3]

Developmental phase:

Genetic mutations
UV radiation exposure
Smoking

Preclinical phase:

Mostly associated with auto-immune antibody production
Autoantibodies common to other systemic autoimmune diseases
Proceeds with a more disease-specific clinically overt autoimmune phase

Clinical phase:

The phase due to damages of the autoantibodies to the body tissues (mostly related to disease itself)
Inflammation
Involvement of first organs
Flares
Involvement of additional organs
Early damages (e.g. alopecia, fixed erythema, cognitive dysfunction, valvular heart disease, avascular necrosis, tendon rupture, Jaccoud’s arthropathy, and osteoporosis)

Comorbidity-complication phase

The phase of damages due to complications of longstanding disease, immunosuppressive therapy, and end organ damages (irreversible damages and complications)

Factors associated with flare up:^[4]^[3]^[5]

Stress (emotional etc.)
Sunlight
Ultraviolet light
Infection
Injuries
Surgery
Pregnancy
Abrupt discontinuation of medications
Treatment noncompliance
Medications
Immunizations
Lupus nephritis
Presence of neurologic complications
Presence of vasculitis
Elevated anti-dsDNA
Low C3 level

Complications

Complications that can develop as a result of prolonged activation of systemic lupus erythematosus or the SLE therapy are:

Prognosis

The prognosis of systemic lupus erythematosus is ranging from a benign illness to an extremely rapid progressive disease that can lead to a fulminant organ failure and death. Without treatment, systemic lupus eryhtematosus will result in a very high mortality rate, with a report of more than 60% mortality rate during the mid-20th century. SLE is associated with a 10 year mortality of more than 50% among patient with nephritis. The presence of nephritis is associated with a particularly poor prognosis among patients with SLE. The increase in survival rate of patients and better prognosis may be due to increased disease recognition with more sensitive diagnostic tests, earlier diagnosis or treatment, the inclusion of milder cases, increasingly judicious therapy, and prompt treatment of complications. Although improvement in SLE diagnosis have led to better prognosis, the mortality rate among SLE patients is still 5 times more than normal population.

Poor prognostic factors for SLE survival:

Presence of nephritis (especially diffuse proliferative glomerulonephritis)
Hypertension
Male sex
Young age
Older age at presentation
Low socioeconomic status
Black race: Higher rate of nephritis
Presence of antiphospholipid antibodies
High overall disease activity

Prognosis markers:^[6]

Serum anti ds-DNA titres correlated with:

- Lupus nephritis
- Progression to end-stage renal disease
- Increased disease severity
- Damage or poor survival

Antiphospholipid antibodies correlated with:

- Features of the antiphospholipid syndrome (APS)
- CNS involvement
- Severe lupus nephritis
- Increase in mortality rate

SLE in men compared to women:^[7]

Less photosensitivity
More serositis
Older age at diagnosis
Higher 1 year mortality compared to women

SLE in the elderly (>65) compared to middle age prevalency:^[8]

Lower incidence of:
- Malar rash
- Photosensitivity
- Purpura
- Alopecia
- Raynaud’s phenomenon
- Nephritis
- Central nervous system involvement
Greater prevalence of:
- Serositis
- Pulmonary involvement
- Sicca syndrome
- Musculoskeletal manifestations
