Define immunity
The normal physiologic response to microorganisms and proteins as well as conditions associated with an inadequate or excessive immune response.
Scope of Concept - Immunity
Ranges from hypo- or suppressed immune response to hyper- or exaggerated immune response
- Normal immune system or a hypo immune system (suppressed or immunocompromise)
Types of Immune Response
Consequences of Suppressed Immune Response
Infection:
- Bacterial
- Fungal
- Viral
Cancer: chemo attacks cancer cells and blood cells
Symptoms and Clinical Findings of Suppressed Immune Functioning
Symptoms:
- Report of frequent infections
- Report of poor wound healing
- Fatigue
- Malaise: overall just ugh feeling
- Weight loss
- Feeling like they are sick all the time
Clinical findings:
- May appear poorly nourished or have wasting syndrome
- May have chronic wounds: non-healing wounds present
- May have enlarged lymph nodes
- Presence of opportunistic infection: odd infections humans never get
Consequences of Exaggerated Immune Response
Consequences of Exaggerated Immune Response
Symptoms and Clinical Findings of Exaggerated Immune Functioning
Symptoms:
- Allergic symptoms: exaggerated immune response to whatever they are allergic to
- Pain
- Fatigue
- Fever
Clinical findings:
- Allergic response
- Mild allergic response
- Severe allergic response
- Autoimmune disorders
- Can range from vague findings to findings associated with organ failure
Diagnostic Testing
Primary Testing:
- Red blood cell count and white blood cell count with differential
- Fluorescent antinuclear antibody (ANA)
- C-reactive protein (CRP)
- Erythrocyte sedimentation rate (ESR)
Primary Prevention
Normal Physiological Process of Immune Response
