A
- An auto immune disease
- Occurs when the immune system attacks healthy tissue in the body
22
Q
SYSTEMIC LUPUS ERYTHEMATOSUS - CAUSE
A
- An auto immune disease
- Occurs when the immune system attacks healthy tissue in the body
- Likely that lupus results from a combination of your genetics and your environment

- However the cause is unknown in most cases
- Some potential triggers include
o Sunlight
o Infections
o Medications
Certain types of blood pressure medications
Antiseizure medications
Antibiotics
People with drug induced lupus usually get better when they stop taking the medication

25
SYSTEMIC LUPUS ERYTHEMATOSUS - CLINICAL PRESENTATION
- Lupus is unique in every case
- S&S may come on suddenly or develop slowly, may be mild or severe and may be temporary or permeant
- Some people have mild disease episodes, called flares, where S&S get worse for a while the improve or even disappear completely for a time

o Severity of the case
o Age
o Type of medications you may be taking
o General health
o Medical history
- Chronic condition that will need to be managed regularly
- The goal of treatment is to get symptoms into remission (not active) and limit the amount og damage the disease does to the organs

SYSTEMIC SCLEROSIS - DEFINITION
- A group of rare diseases that involve the hardening and tightening of the skin
- May also cause problems in the blood vessels, internal organs and digestive tract
29
SYSTEMIC SCLEROSIS - CAUSE
- Results from an overproduction and accumulation of collagen in body tissues
- Collagen is a fibrous type of protein that makes up the body’s connective tissues, including the skin
- The exact cause for this process to begin is unknown
- The body’s immune system is thought to play a role
- Most likely that scleroderma is cause by a combo of factors including
o Immune system problems
o Genetics
o Environmental factors
30
SYSTEMIC SCLEROSIS - POPULATION AFFECTED
Women aged 30 – 50
31
SYSTEMIC SCLEROSIS - RISK FACTORS

o Believed to be an autoimmune disease
32
SYSTEMIC SCLEROSIS - CLINICAL PRESENTATION
- Symptoms vary from person to person, depending on which parts of the body are affected
- Skin-related signs and symptoms

- No cure
- Can live a healthy life with this disease
- Treatment is directed at controlling and managing the symptoms
- Because scleroderma can have many symptoms, a combo of approaches is often needed to treat and manage the disease
o Skin treatments
o Digestive remedies
o Treatment for lung disease
- Management for scleroderma
o Exercise
o Jt protection
o Skin protection
o Diet
o Dental care
o Stress management
