Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
NBUVB is a proven, effective, and well-accepted treatment as part of the standard of care for vitiligo. NBUVB has a sharp emission peak at 311-313 nm. NBUVB is a relatively safe treatment modality, but can cause phototoxic reactions and tanning. Studies have shown that treatment with NBUVB improves the Vitiligo Area Scoring Index by 42% over a period of 6 months. Approximately half of patients should expect 50% repigmentation by 6 months of 2-3x per week phototherapy (4-6). However, a portion of patients are slow responders requiring up to 72 treatments before notable repigmentation has been achieved.
To complicate matters further, about 1/3 of the patients with vitiligo do not photoadapt, meaning the patient does not exhibit a diminished erythema (redness) to equivalent doses of NBUVB upon future irradiations (7). Photoadaption is the principle behind needing to increase the NBUVB dose for all phototherapy regimens (atopic dermatitis, psoriasis, mycosis fungiodes, vitiligo, etc) and why people are able to tolerate longer solar exposure at the end of summer rather than the beginning. It is thought that the non-photoadapters do not respond to NBUVB as their photoadpative capacity may be genetically predetermined (7).
Repigmentation from NBUVB therapy has shown dramatic improvements in quality of life scores (QOL). Tijoe et. al reported 70% improvement in QOL with long term UVB therapy (8). Therefore, identifying adjunctive therapies that can enable non-photoadapters to safely tolerate therapeutic NBUVB doses can significantly raise their QOL. In addition, these therapies can be expanded into the treatment of photoadapters receiving NBUVB to permit higher dose escalations and fewer phototherapy sessions to achieve a therapeutic NBUVB vitiligo dose. This can in-turn potentially decrease health care costs for increased treatments. Also, the patient may experience fewer long-term side effect associated with NBUVB since they may need fewer sessions of NBUVB.
A possible way for non-photoadapters to tolerate NBUVB may be with the use of NSAIDs. Studies performed have shown that the use of NSAIDs showed increased minimal erythema dose by possibly suppressing the immune response by inhibiting cyclooxygenase and prostaglandins (9). Ibuprofen has also shown to decrease inflammation induced by UVB phototherapy (10). Thus, ibuprofen may increase the MED in non-photoadapters.
Therefore, the goal of this study is to see if the use of ibuprofen, an NSAID, will allow for nonphotoadpaters to respond to NBUVB treatments.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention group
There is one group in this study and they will receive ibuprofen 400 mg before their narrow band UVB phototherapy session which occurs two to three times weekly. The treatment dose of NBUVB will start off at 150 mJ/cm2 and will be increased 10% as tolerated til the patient reaches 700 mJ/cm2. They will receive ibuprofen before each phototherapy session.
Ibuprofen
Patient will receive ibuprofen 400 mg before the phototherapy session.
