The Basics

• Autoimmunity occurs when the body is unable to differentiate “self” from “non-self”

–Results in overactive immune response against own cells and tissues

• Affects 5%-8% of the population

–78% affected are females

• Over 100 conditions linked to autoimmunity

–15 diseases directly linked to autoimmune response

Pathogenesis of Autoimmunity

• Genetic predisposition and environmental factors relevant

– Immunoglobulins, T cell receptors, major histocompatibilty complex

• T Cell Bypass- The requirement of T cells to activate B cells in order to produce large amounts of antibodies is bypassed

• Molecular Mimicry- An exogenous antigen shares structural similarities with host antigen and when an antibody is produced, it can bind to host antigen

• Idiotype Cross Reaction- A cross reaction between the idiotype (molecule recognized by antigen) on an antiviral antibody and a host cell receptor for the virus in question

• Cytokine Dysregulation- Certain cytokines have a role in the prevention of the exaggeration of pro-inflammatory immune response

• Dendritic Cell Apoptosis- Defective dendritic cells can lead to inappropriate systemic lymphocyte activation and a decline in self tolerance

Symptoms

• Tiredness

• Depression

• Weight gain

• Weight loss

• Muscle weakness

• Cramps

• Irritability

• Sweating

• Shaky

• Swelling

• Rash

• Body pains

• Tremors

• Numbness

• Fatigue

• Loss of appetite

• Insomnia

• Coordination loss

Many different symptoms make autoimmune disorders hard to diagnose

Many times there are no symptoms!

Workup

• History and Physical

• Markers of inflammation (ESR, CRP)

• Markers of immune activation (C3/C4)

• Imaging studies (hand/foot radiographs)

Autoantibody Tests

• ANA

• DS-DNA

• CCP

• Ro/La

Clinical Features related to disability

• Constitutional and multisystem effects

• Chronic, no cure

• Exacerbations (flares) and remissions unpredictable but usually treatable

• Treated with immunosuppressive medications – side effects

• Comorbidities due to organ damage, to medication side effects, to long term disease/treatment effects and to other factors (eg psychological)

14

Major Features of Active Autoimmune disease

• Constitutional – fatigue, malaise, fever, arthralgia, myalgia

• Variable organ involvement

– Arthritis, pleurisy, pericarditis

– Raynauds phemomenon, vasculitis, stroke

– Mucocutaneous – rashes, oral ulcers, sicca syndrome,

– Kidney, CKD, NS

– Neuropsychiatric – psychosis, seizures, transverse myelitis

• Variable abnormalities in laboratory testing

– High ESR, CRP, anemia, low WBC, platelets, abnormal urinalysis

– RF, ACPA, Anti Scl-70, anti-DNA, low complement levels (C3, C4)

The damages

• Disease damage

– CKD, cognitive dysfunction, ovarial failure

• Drug related

– Obesity, hypertension, diabetes

– osteoporosis, avascular necrosis

– Dyslipidemia

– Striae

• Premature atherosclerotic disease

– heart attack, stroke, heart failure

• Infection … opportunistic

19

Life threatening

20

Management principles

• Diagnosis

• Disease activity, severity, damage ?

• Start remission induction disease control

• Treatment follow up and maintenance

• Non medicinal approaches

• Patient education and family involvement

• The role of support group

21

The goal of treatment

• Symptoms control

• Disease activity as low as possible

• Less medicinal side effects

• Monitor co-morbidity and infection

• Quality of life maintenance

Remission induction Immunosuppression

• Reduce the activation or efficacy of the immune system

• Leaves body very vulnerable to opportunistic infections

25

Immunosuppression

• Steroid

• Azathioprine

• Cyclosporine

• Mycophenolic acid

26

Treatments- Anti-Inflammatory

• Remedy pain by reducing inflammation

• Steroidal

• Nonsteroidal

–Cox 1 selective, Cox 2 selective

27

Disease Modifying Drugs

• Improve symptoms

• Alter disease course --- disease activity

• Improve radiographic outcomes

28

Disease Modifying Drugs

• Methotrexate

• Chloroquine

• Sulfasalazine

Biologic therapies

• B cell elimination:• B cell depleting: anti-CD20

• B cell depleting/modulating: anti-CD22

• Specific autoreactive B cell depletion: LJP394

• Co-stimulatory blockade:

• anti-CD40L, CTLA4-Ig, anti-ICOSL

• Other: anti-cytokine, anti-survival factors, factors up-stream and down-stream of B cells

• anti-BAFF, TACI-Ig• anti-IL-10, anti-IL-6• anti-IFNB Cell inhibitor• anti-TNF , LTaB• anti-CXCL13• proteasome inhibition

31

Features of autoimmune disorderswhich can lead to disability

• Related to disease activity

– constitutional

– structural organ effects

• Related to medication effects

• Functional changes “related to AID” but not to active disease**

**common

malaise, fatigue, fever

renal insufficiency/failure, deforming arthritis, disfiguring skin rash

acute and chronic infections, bone and joint damage, mood swings, weight gain, hypertension, diabetes

chronic fatigue, chronic muscle and joint pains, neurocognitive dysfunction, depression

32

Comorbidities

(various causes, independent of disease activity)

• Organ damage (prior activity)

– kidney, brain (neurocognitive, stroke-extremity weakness)

• Medication effects (corticosteroids)

– obesity, hypertension, diabetes

– osteoporosis, avascular necrosis

• Premature atherosclerotic disease

– heart attack, stroke, heart failure

• Other

– Fibromyalgia

– Cognitive dysfunction

– Depression

– Chronic fatigue

33

Social Aspects in SLEExtent of the Problem

• Cohort of 159 patients with SLE working since diagnosis (Partridge et al: Arthritis Rheum 1997; 40:2199)

– 40% quit work completely average of 3.4 years after diagnosis

– substantial job modifications

– predictors of early work disability – lower education status (no college), health insurance status, physical rather than mental job, low income, greater disease activity at time of diagnosis

• Inception cohort of 273 SLE patients (Bertoli et al: Ann Rheum Dis 2007; 66:12)

- 19% self-report of disability at 5 years (25% in AA)

- predictors – age*, longer disease duration, male, poverty*, less social support, higher disease activity and damage index

34

Summary

• Confirm the diagnosis if possible

• Disease activity, severity, chronicity (damage) assessment

• Co-morbidity ? Infection…

• Induction of remission

• Tight follow in a while, treatment maintenance

• See if there is any psycho-socio-economic burden patient educations, relatives and support group involvement

35

Emotional and Spiritual support

36

Role of the Physician

Can help with elucidation of diagnostic features and severity of organ involvement, medications used, comorbidities

• Better to ask to support group help than to handle it one man show

• Invite close relatives to participate in supporting the patients

• Emotional, spiritual and continuous educational approach

Please be respectful of physician’s limited time
