Systemic Lupus Erythematosus (SLE)
Bismillahirahmanirahim, for today there is some sharing i want to give all of reader to read and know a one of the autoimmune disease that can be threatening in your life , its called SLE.
What is SLE?
·
Autoimmune
disease
·
Characterised
by inflammation of various tissues and organs in the body
Breaking it Down
·
Lupus:
means wolf, refer to lesions of the skin that looks like its been attacked by a
wolf
·
Erythematosus:
redness of the skin caused by inflammation
·
Systemic:
can affect tissues and organs right throughout the body
·
Systemic
Lupus Erythematosus
What happens in the body?
·
Body’s
immune system produces antibodies against itself
·
Abnormalities
in apoptosis (programmed cell death)
·
T
and B cells become overactive and attack self-antigens
·
Inflammatory
and autoimmune response activated.
Signs and Symptoms
·
Common
symptoms:
Ø Non-specific fatigue
Ø Rashes
Ø Fever
Ø Joint pain
Ø Weight changes
Dermatological Changes
·
65%
of SLE patients develop skin rashes
·
Commonly
on the face, neck, upper chest and elbows
·
Butterfly-like
patchy redness appearance (Malar butterfly rash)
·
Can
be made worse with exposure to the sun
Malar Rash ( Butterfly Rash) |
Musculoskeletal Problems
·
90%
of SLE patients have joint pain
·
May
develop joint deformity (~10%)
·
Most
commonly affects:
Ø Fingers
Ø Hands

Lymph Node and Spleen Problems
·
Inflammation
or enlargement of lymph nodes are quite common
·
Splenomegaly
occurs in 10% of SLE patients

e.g. Weakness and change in sensation
Gastrointestinal Tract Problems
·
Liver,
pancreas or GIT can be involved.
·
Signs
and Symptoms:
Ø Abdominal pain
Ø Nausea
Ø Indigestion
Renal Problems
·
Kidney
is the most commonly affected viseceral organ
·
50%
of SLE patients develop renal disease
·
Symptoms
related to fluid overload
·
Kidney
transplant may be required
Haematological Problems
·
Anaemia
in up to 50% of cases
·
RBC,
WBC and platelets may decrease
·
Difficulty
in blood clotting
Ø Bleeding/harmorrhages may occur
Respiratory problems
·
Pleurisy
is very common
·
Occasionally
a pleural effusion is present
·
Other
lung conditions:
Ø PE (Pulmonary Edema)
Ø Chronic interstitial lung disease
Ø Chest infections
Ø Alveolar haemorrahge
Ø Symptoms:
Ø Pleuritic chest pain
Ø Dyspneoa
Ø Haemoptysis
Jonsson et al 1989
·
Studied
the lung function in patients with SLE and persistent chest symptoms
·
Dyspnoea
and Thoracic chest pain
·
They
found that lung function was preserved despite the chronic chest symptoms
Cardiovascular Problems
·
Pericarditis
is the most common cardiac manifestation of SLE
·
Other
conditions:
Ø Coronary artery vasculities
Ø Myocarditis
·
Symptoms:
Ø Chest pain
Ø Angina
Ø Fatigue
Diagnosis
·
Based
on individual’s symptoms and findings
·
Blood
tests and urine tests may be performed
·
Anti-nuclear
antibody (ANA) test
·
Anti-DNA
test
·
Antiphospholipid
antibody test
·
Other
blood tests: to check levels of complement proteins in blood, RBC and WBC
count, platelet counts etc.
Characteristics of Lupus
American Rheumatism Association established 11 criterias and
4 have to be met for SLE:
·
Butterfly-shaped
like rash on face
·
Typical
rash on other parts of body
·
Increased
sensitivity to sunlight
·
Mucous
membrane ulcers
·
Joint
inflammaation
·
Serositis
·
Kidney
dysfunction
·
Low
WBC count, low RBC count or low platelet count
·
Nerve
or brain dysfunction
·
Immunologic
disorder
·
Antinuclear
antibodies in the blood
Aetiology
·
Unknown
·
Popular
hypothesis: Viral infection
·
Other
causes:
Ø Genetics
Ø Hormonal factors
Ø Ultraviolet light
Ø Medications
Ø Pregnancy
Ø Environmental factors
Incidence and Prevalence
·
90%
of lupus patients are women
·
Prevalence
highest among women aged 14-64 years
·
In
the United States:
Ø 1.4 million people affected
Ø 1/2000 in US has SLE
Ø 1 in 250 young, African-American
women
·
In
Australia
Ø 1 in 700 Australians affected
Ø Over 17000 people has SLE
Prognosis
·
No
cure
·
Flare
ups and remissions
·
97%
of patients live >5years after diagnosis
·
90%
of patients live >10 years after diagnosis
·
Patients
with mild SLE can live a relatively normal life span
·
Life
expectancy varies for severe SLE patients
·
Common
cause of death:
Ø Kidney failure
Ø Central nervous system dysfunction
Ø Infections
Ø Cardiovascular disease
Treatment
·
Aimed
at reducing inflammation and controlling abnormalities in the immune system
·
Address
sleep quality, lack of exercise and self-care strategies
·
Avoid
excessive sun exposure
·
Medications:
Ø NSAIDS
Ø Anti-malarial drugs
Ø Corticosteroids
Ø Immunosuppressants
NSAIDS
·
Used
for pain relief
·
Suppress
inflammation
·
Relieves
fevers, headaches, muscle aches, malaise and arthritis
·
Side-effect:
·
High
GIT toxicity
·
Stomach
irritation
·
Stomach
ulcers
·
Alternative/newer
medication: COX-2 inhibitors
Anti-malarial drugs
·
Hydroxychloroquine
and Chloroquine
·
Helps
with skin rashes, fatigue, mouth ulcers and hair loss
·
May
also decrease joint swelling and aching
·
Side-effect:
Ø Nausea
Corticosteroids
·
Example:
Prednisone
·
Used
to reduce inflammation and controlling disease activity of lupus
·
Used
for moderate to severe lupus
·
Side
effects:
Ø Osteoporosis
Ø Heart palpitations
Ø Tachycardia
Ø Hypertension
Ø Weight gain
Ø Diabetes
Ø Sleeplessness
Immunosuppressants
·
Example:
Methotrexate, Cyclophosphamide and azathioprine
·
Used
to suppress the body’s over-active immune system
·
For
more severe manifestations of SLE
·
Side
effects:
Ø Depress blood-cell counts
Ø Cause anaemia
Ø Increase rick of infections
Ø Increase risk of bleeding
Advice for patients living with Lupus
·
Encourage
the patient to exercise
·
Advise
the patient to get plenty of rest and to take a rest if they feel fatigued
·
Advise
patient to avoid excessive exposure to the sun.
·
Avoid
contact with people who have an infection
Systematic Review by Neill et al 2006
·
Effectiveness
of non-pharmacological interventions for fatigue in adults with multiple sclerosis,
rheumatoid arthritis, or systemic lupus erythematosus.
·
The
review suggest that aerobic exercise whether home-based or supervised classes,
is an effective non-pharmacological means of managing fatigue for people with
SLE.
·
Low-impact
aerobics, walking, cycling and jogging were effective interventions.
Relevance to physiotherapy
1. Knowing what SLE is
2. How it would affect your treatment
3. Encourage patient to exercise to
improve aerobic capacity (Celeste Robb-Nicholson et al 1989)
4. Understand the effects of longstanding
medications SLE patients have been on
