“Why Is My Psoriasis Getting Worse Even After Trying Biologic Treatment?”

A Real Patient Case from Village Dermatology in Katy & Houston, Texas

Psoriasis can be frustrating—especially when it flares despite prior advanced treatments. At Village Dermatology, we often help patients navigate moderate-to-severe psoriasis when standard therapies are no longer effective.

This case highlights a 35-year-old male with widespread psoriasis who previously failed biologic therapy and required a more advanced treatment approach.

Patient Case Overview

The patient presented with:

  • Flaking, itchy, scaly plaques on the face, trunk, and arms

  • Symptoms present for several months with worsening severity

  • Prior treatment with Humira (adalimumab) without sustained control

On exam:

  • Psoriasiform plaques with micaceous scale

  • Body Surface Area (BSA): 40% involvement

  • Itch severity: 8/10

Importantly, the patient denied joint pain, indicating no current signs of psoriatic arthritis.

What Is Psoriasis?

Psoriasis is a chronic autoimmune skin condition that speeds up skin cell turnover, leading to:

  • Thick, scaly plaques

  • Red or inflamed skin

  • Itching and discomfort

Common triggers include:

  • Stress

  • Infections (like strep throat)

  • Certain medications

  • Alcohol use

Psoriasis often follows a pattern of flares and remissions, requiring long-term management.

Why Do Some Treatments Stop Working?

Many patients ask why their psoriasis worsens even after biologic therapy.

The reality is:

  • The immune system can adapt or become less responsive to certain biologics over time

  • Missed or delayed doses can lead to disease flare-ups

  • Each biologic targets a different immune pathway, so switching may be necessary

In this case, the patient had been off Humira for over a year, contributing to a significant flare.

Advanced Treatment: Skyrizi (Risankizumab)

Given the severity and prior treatment failure, we initiated Skyrizi, a newer biologic therapy.

Why Skyrizi?

  • Targets IL-23, a key driver of psoriasis inflammation

  • Effective for moderate-to-severe psoriasis

  • Convenient dosing:

    • Week 0

    • Week 4

    • Then every 12 weeks

Supporting Treatments

While starting biologic therapy, we also recommended:

Topical Steroid

  • Triamcinolone ointment for flare control

Medicated Shampoo

  • Ketoconazole shampoo to manage scalp involvement

Skin Care Measures

  • Daily moisturizers

  • Controlled sun exposure

  • Anti-dandruff shampoos (zinc, selenium, tar)

Safety and Monitoring

Because biologics affect the immune system, proper screening is essential.

Baseline Labs Ordered:

  • Tuberculosis screening (QuantiFERON-TB Gold)

  • Hepatitis B & C testing

  • HIV screening

  • Complete blood count and metabolic panel

Ongoing Monitoring:

  • Annual TB testing

  • Watch for signs of infection

Patients are carefully counseled on risks such as immunosuppression and infection.

When Should You See a Dermatologist?

You should seek expert care if:

  • Psoriasis covers large areas of the body

  • Symptoms interfere with daily life

  • Treatments are no longer effective

  • You experience frequent or severe flares

Early intervention can significantly improve outcomes and quality of life.
