Psoriasis Case Study: K.B.

Question 1: Psoriasis Triggers and Clinical Types

Triggers: While the exact cause of psoriasis is unknown, several triggers can worsen existing symptoms or lead to flare-ups, including:

• Stress:Emotional and psychological stress can significantly impact the immune system, contributing to psoriasis flares.
• Skin injury:Cuts, scrapes, sunburns, and other skin traumas can trigger the development of new psoriatic lesions in a phenomenon called the Koebner phenomenon.
• Infections:Certain infections, particularly upper respiratory infections like strep throat, can be triggers for psoriasis flares.
• Medications:Some medications, like beta-blockers, lithium, and antimalarials, can worsen psoriasis.
• Alcohol and smoking:Excessive alcohol consumption and smoking are established risk factors for psoriasis and can exacerbate symptoms.
• Certain foods:While individual responses vary, some people with psoriasis experience flare-ups after consuming specific foods like gluten, dairy, or nightshades.
• Climate:Cold and dry weather can worsen psoriasis, while sun exposure often provides temporary relief.

Clinical Types:

• Plaque psoriasis (most common):Characterized by raised, red, and scaly patches typically on elbows, knees, scalp, lower back, and buttocks. K.B.’s case falls under this type.
• Guttate psoriasis:Small, teardrop-shaped lesions typically appearing after a streptococcal infection, often in children and young adults.
• Inverse psoriasis:Smooth, red, and inflamed patches in skin folds like armpits, groin, and genitals.
• Pustular psoriasis:Rare and severe form with small, sterile pustules on red skin, most commonly affecting hands and feet.
• Erythrodermic psoriasis:Widespread inflammation and redness covering most of the body surface, a life-threatening condition.

Question 2: Treatment Options for K.B.

Types of Treatments:

• Topical Treatments:Corticosteroids, calcineurin inhibitors, vitamin D analogues, retinoids, coal tar, and anthralin. These are often first-line treatment due to their ease of use and safety.
• Phototherapy:Ultraviolet B (UVB) light therapy can slow skin cell growth and reduce inflammation.
• Systemic Medications:Methotrexate, cyclosporine, acitretin, apremilast, and biologics like adalimumab and ustekinumab are used for moderate to severe psoriasis or when topical treatments and phototherapy are ineffective.
• Non-Pharmacological Options:Stress management, dietary changes, weight management, maintaining healthy sleep patterns, and joining support groups can significantly improve quality of life.

Most Appropriate Approach for K.B.:

Considering K.B.’s previous successful treatment with high-potency corticosteroids and the limited nature of the relapse, topical corticosteroids might be initially considered. However, due to the widespread involvement of multiple body areas and the previous longer remission period, phototherapy or combination therapy with topical corticosteroids and phototherapy could be explored. Ultimately, the specific treatment plan should be determined by the dermatologist based on K.B.’s individual needs and preferences.

Medication Review and Reconciliation:

This is crucial for several reasons:

• Drug interactions:Certain medications can worsen psoriasis or interact with prescribed treatments.
• Contraindications:Some medications can be contraindicated in psoriasis patients due to underlying conditions or potential side effects.
• Treatment adjustments:Depending on the medications K.B. is taking, adjustments to her psoriasis treatment plan or vice versa might be necessary.

Question 3: Other Manifestations of Psoriasis:

• Psoriatic arthritis:Affecting up to 30% of psoriasis patients, it causes joint pain, stiffness, and inflammation.
• Nail psoriasis:Pitting, thickening, discoloration, and crumbling of nails.
• Eye involvement:Conjunctivitis and blepharitis can occur.
• Psoriatic erythroderma:Life-threatening widespread inflammation and scaling of the skin.
