Study Notes
Psoriasis Overview
- Chronic Inflammatory Disorder: Affects skin characterized by plaque psoriasis, leading to red, scaly patches.
- Associated Cytokine: IL-23 is a significant factor in the pathogenesis of psoriasis.
- Common Symptoms: Include plaque formation and itchiness, often affecting quality of life.
Risk Factors for Psoriasis
- Infections: Both viral and bacterial infections can trigger or exacerbate psoriasis.
- Drugs: Certain medications may worsen psoriasis symptoms.
- Obesity: Increased body mass index (BMI) is correlated with higher incidence and severity of psoriasis.
- Alcohol Consumption: Excessive drinking can act as a trigger.
- Physical Inactivity: Lack of exercise is linked to increased risk.
- Smoking: Tobacco use is a known risk factor for psoriasis development.
- Emotional Stress: Psychological stress can lead to flare-ups.
Treatment Options
-
Systemic Treatments:
- Psoriatic Arthritis (PAS): Treatments are needed for associated joint issues.
- Moderate to Severe Psoriasis: Newer treatments generally address moderate to severe cases effectively.
- Biologics: Target specific components of the immune system, primarily IL-23.
Complications of Psoriasis
- Increased Infection Risk: Higher vulnerability to infections such as sepsis, pneumonia, meningitis, urinary tract infections (UTIs), and skin/soft tissue infections.
- Emotional Distress: The skin condition can lead to emotional stress, impacting mental health and quality of life.
Allergic Reactions
- Severity: Range from mild skin rashes to severe anaphylactic reactions.
- Common Triggers: Include various medications and substances that may cross-react with psoriasis treatment options.
Mechanism of Action
-
Streptogramins:
- Target bacterial protein synthesis, effective against various infections.
- Resistance Mechanisms: Resistance can occur through altered drug-target interactions and enzymatic degradation.
Side Effects of Treatment
- Gastrointestinal Effects: Possible side effects include nausea, vomiting, diarrhea, and abdominal pain.
- Blood Disorders: Risks include anemia, leukopenia, and thrombocytopenia due to bone marrow suppression.
- Liver and Kidney Toxicity: May lead to elevated liver enzymes and impaired renal function.
- Electrolyte Imbalance: Can cause symptoms such as muscle cramps and weakness.
Conclusion
- Psoriasis is not just a superficial skin condition; it has complex systemic implications, necessitating a multifaceted approach for management and treatment. Understanding risk factors and potential complications is vital for effective care and patient quality of life.
