VITILIGO
• Acquired white macules/patches on the body
• 0.5 – 2% of the world’s population affected
• No racial or gender predominance
7Alkhateeb et al. Pigment Cell Res. 2003;16:208
VITILIGO ETIOLOGY
• Absence of melanocytes in the epidermis of affected
areas
• Likely multifactorial etiology
• Genetic predisposition
– 1 in 6 pts have a 1st degree relative with the disease
• Autoimmunity
– T-cells attacking melanocytes
• Oxidative Stress
– ROS involved in melanocyte destruction8Alkhateeb et al. Pigment Cell Res. 2003;16:208
FOCAL VITILIGO
• Confined to a limited area (non-dermatomal)
• Most responsive to medical management
10
SEGMENTAL VITILIGO
• Quasidermatomal distribution
• Usually unilateral
• Decreased progression after 2 years
• Usually more resistant to medical
treatment
• Most responsive to surgical treatment
11Park JH et al. Ann Dermatol. 2014;26:6, Mulekar SV. Int J Dermatol. 2003;42:132
ACROFACIAL VITILIGO
• Cases in which there is involvement of the
fingers/toes and perioral regions
• Lesions on ANY part of the body are less
responsive to all treatments
13
SIGNS OF ACTIVE VITILIGO
• Patient subjective report of rapid spread
• Koebner phenomenon
• Trichrome lesions
• Inflammatory lesions
• Confetti-like depigmentation
15Rodrigues et al. JAAD. 2017;77:1
ASSOCIATIONS
• Nearly 20% of vitiligo patients have at least 1 comorbid
autoimmune disease
• Autoimmune thyroid disease: ~15.1%– Check baseline TSH, annual recheck vs symptom screen at follow-up
• Less common associations: AA, IBD, pernicious anemia
• Newer associations: DLE, Guillain-Barre, linear
morphea, myasthenia gravis, Sjogren

COVER-UP BRANDS
• Dermablend (Macy’s), CoverFx (Sephora), CoverBlend
(Ulta), Iman Cosmetics (Target), Kat Von D (tattoo cover-
up, Sephora)
• Microskin
– Liquidized formulation
– Waterproof and resistant to frictional rubbing
– Lasts up to several days
– Computer color-matched (Pasadena, CA and NY, NY)
– Hundreds to thousands of dollars per year
23Hossain C et al. J Drugs Dermatol. 2016;15:4
DIHYDROXYACETONE
• Self-tanning products
– Clarins
• Concentrations range from 2.5-12%
– Darker skin, higher concentration
• Safe, inexpensive
• Water resistant, last up to a week
24Hossain C et al. J Drugs Dermatol. 2016;15:384
TOPICAL IMMUNOSUPPRESSANTS
• Focal > generalized vitiligo
• Class 3/4 topical corticosteroids (TCS) x 3-4 months → 75%
repigmentation in 55-56% of patients with localized vitiligo
• Calcineurin inhibitors and TCS have statistically equivalent
efficacy
• Face/neck - Calcineurin inhibitors preferred alternative
• Body - ? Increased efficacy of Class 1/2 TCS
– Non-statistically significant increased efficacy of topical corticosteroids on
the body
– Possible faster and increased efficacy observed clinically
25Njoo M.D et al. Arch Dermatol 1998;134:1532, Ho N et al. Br J Dermatol. 2011;165:626
TOPICAL RETINOIDS
• Placebo-controlled, paired-comparison, left-right study
• 50 patients diagnosed with generalized vitiligo received 6 months
of tretinoin plus topical corticosteroid and the vehicle plus the
same corticosteroid (vehicle plus)
• 55% showed a better response to tretinoin plus than to vehicle
plus
• The improved response was noted at an early stage of treatment,
during the first 3 months in 60% of patients
• Topical tretinoin is known to prevent skin atrophy induced by
long-term use of topical corticosteroids
26Kwon HB et al. J Drugs Dermatol. 2013;12:e63-7.
ANTIOXIDANTS
• Oxidative stress involved in pathogenesis
• α-Lipoic Acid • 100 mg daily
• Best combined with NB-UVB
• Gingko Biloba• 60 mg twice per day
• Best at halting slowly spreading disease
• Foods (blueberries)
28Dell'Anna ML et al. Clin Exp Dermatol. 2007;32:631, Parsad D et al. Clin Exp Dermatol. 2003;28:285,
Szczurko O et al. BMC Complement Altern Med. 2011;11:21
MINOCYCLINE
• Antibiotic with anti-inflammatory, free-radical scavenging
properties
• Used in 32 patients with slowly spreading vitiligo at a dosage of
100 mg daily for 3 months
– Stopped spread in 29/32 (91%)
– Repigmentation in 7/32 (21%)
• RCT of 50 patients found that 6 months of minocycline was
comparable to oral mini-pulse steroids (2.5mg dexamethasone for
2 consecutive days/week x6 months) in stopping actively
spreading disease
29Parsad D et al. Dermatol Ther. 2010;23:305, Indian J Dermatol Venereol Leprol. 2014;80:29
ORAL STEROIDS AND VITILIGO
• Indicated for halting rapidly spreading vitiligo
– Confetti-like macules, koebnerization, new lesions
• Oral minipulse therapy
– Dexamethasone 2.5mg-10mg daily on the weekends
only x 3-6 months
– Minimizes adverse effects
30Kanwar A et al. J Cutan Med Surg. 2013;17:259, Majid I et al. Indian J Dermatol 2013;58:113
ORAL STEROID COMBINATION THERAPY
• Protocol developed by Dr. Hamzavi for patients with
recalcitrant widespread vitiligo
• NB-UVB TIW
• Oral corticosteroids
– Stepwise progression
– Minipulse dosing with dexamethasone 4mg daily on weekends
– Prednisone 20mg QOD
– Prednisone 20mg daily
• D/c after repigmentation plateaus or 6 months of
corticosteroids31

REPIGMENTATION MAINTENANCE
THERAPY
• With successfully repigmented patients, 44% relapse
after treatment is discontinued
• Focal vitiligo – tacrolimus 0.1% ointment BIW
significantly reduces risk of local recurrence
• Generalized vitiligo
– gingko biloba and minocycline effective anecdotally
– Tapering of phototherapy may be necessary
33Cavalié et al. J Invest Dermatol. 2015;135:970, Nicolaidou et al. JAAD. 2007;56:274
AFAMELANOTIDE
• Afamelanotide is a synthetic analogue of
melanocyte-stimulating hormone (α-MSH)
• Rationale: defects in the melanocortin system in
vitiligo patients
– Decreased serum and lesional α-MSH
• α-MSH helps restore this deficiency and
stimulates melanocyte reproduction and growth
34Lim HW et al. JAMA Dermatol. 2015;151:42
AFAMELANOTIDE
• Randomized, controlled, multi-center clinical trial
(Including Henry Ford Hosp)
• Afamelanotide subcutaneous implants plus NB-
UVB (combination therapy) vs NB-UVB
monotherapy x 6 months
• 55 nonsegmental vitiligo patients with Skin
Phototypes III to VI
35Lim HW et al. JAMA Dermatol. 2015;151:42
AFAMELANOTIDE
• Combination therapy yielded significantly superior
(48.64% vs 33.26%) and faster (41-46 days vs 61-69 days)
repigmentation of the face and upper extremities
• Hyperpigmentation of unaffected skin reported in 2
patients (7%) in the combination therapy group
– Other AE: nausea and abdominal pain

JAK INHIBITORS
•Janus Kinase (JAK) enzyme inhibitors act
as immunosuppressors–JAK → ↑ IFN-γ → active CXCL10 → immune
system activation
•Tofacitinib – JAK 1/3 inhibitor
•Ruxolitinib – JAK 1/2 inhibitor
39
TOFACITINIB
• FDA approved: rheumatoid arthritis
• Off-label : alopecia areata, plaque psoriasis
• Case report of 1 woman in her 50s with generalized
vitiligo (~10% BSA)
• Treated with 5 months of PO tofacitinib - 5 mg QOD x 3
weeks, then daily
• Substantial repigmentation at 5 months
– Significant repigmentation of hands
– BSA decreased to 5%40Craiglow, King. JAMA Dermatol. 2015;Jun 24:E1
RUXOLITINIB
• FDA-approved for myelofibrosis and
polycythemia vera
• Case report of a 35-year-old man with widespread
vitiligo including > 99% facial depigmentation
• Improved to 51% repigmentation of his face with
ruxolitinib 20mg BID x 20 weeks
42Harris et al. JAAD. 2016;74:370
SIDE EFFECTS AND MONITORING
• Tofacitinib Side effects
– Immunosuppressive effects – Increased risk of
infection (upper respiratory tract infection, UTI) and
possible increased risk of cancer (lymphoma, non-
melanoma skin cancer)
– HTN, transaminitis, increased creatinine and lipids
• Tofacitinib Monitoring – BP, CBC, CMP, lipids
• Similar for ruxolitinib
44
TOPICAL JAK INHIBITORS
• If effective, should be safer and cheaper than the systemic agents
• Ruxolitinib 1.5% cream BID x 20 weeks in 12 patients
– Overall: 23% decrease in VASI
– Facial vitiligo (n=4): 76% improvement in facial VASI
– 3 of 8 responded on body surfaces, 1 of eight responded on acral surfaces
• Multi-center, phase III clinical trial using varying concentrations
and dosing regimens of ruxolitinib cream is ongoing (HF is one of
the sites)
45Rothstein B et al. JAAD. 2017;76:1054
CYCLOPHOSHPHAMIDE
• 50mg daily (normal dose is ≥ 80mg daily)
• repigmentation in 30/33 patients
• including some acral lesions
• many pts had failed PUVA
• side effects reported were nausea, transient hair
loss (4), and transient leukopenia (degree or
number of subjects not mentioned)
46Gokhale B. Int J Dermatol. 1979;18:92
METHOTREXATE
• MTX 12.5 -25mg weekly resulted in “clinically significant”
repigmentation in 3 pts
– response ≥ 6 weeks
– including 2/3 patients who previously failed TCIs and
phototherapy
– Including repigmentation of acral involvement
• MTX 10mg per wk and dexamethasone 5mg weekly
(OMP) x 6 mo equivalent in preventing new lesions
development in actively spreading vitiligo
47Garza-Mayers AC. J Drugs Dermatol. 2017;16:705, Singh H et al. Dermatology. 2015;231:286
APREMILAST
• Case report

various topicals, PUVA, IM/PO steroids, and cyclosporine
• Apremilast 30mg BID x 11 months with IM triamcinolone
x 2
• 60-70% repigmentation of her chest and arms, including
her hands
48
SB. Case Rep Dermatol Med. 2017;20174:2386234
TARGETED PHOTOTHERAPY
• Localized vitiligo
• Excimer laser
• Rapid induction of repigmentation and fewer treatments
compared to conventional NB-UVB
– Treatment twice per week x 6 months
– >75% repigmentation in 49% of patients
50
Leone G et al. J Eur Acad Dermatol Venereol. 2003;17:531
WHOLE-BODY PHOTOTHERAPY
• Generalized vitiligo
• NB-UVB preferred modality
• >75% repigmentation by duration of tx– 3 mo – 13%
– 6 mo – 19.2%
– 12 mo – 35.7%
• 6-12 mo of NB-UVB by location
– Face/neck – 44.2%
– Trunk – 26.1%
– Extremities – 17.3%
51Bae J et al. JAMA Derm. 2017;153:666
COMBINATION PHOTOTHERAPY
• Synergistic effect with topicals
• Tacrolimus
– Enhances response
• Reduction in mean lesion size of 29% (NB-UVB alone) vs 42.1% (plus
Tac)
– Enhances repigmentation rates
• > 75% repigmentation in 19% (excimer laser alone) vs 50% (plus Tac)
• Pimecrolimus and topical steroids also potentiate effects of
phototherapy for facial vitiligo

NB-UVB PHOTOTHERAPY CONSENSUS
RECOMMENDATIONS
• Full Global Vitiligo Foundation recommendations
available on www.vitiligoworkinggroup.com
• Goal is for vitiligo lesions to turn a light pink (carnation
color) following treatment
• Frequency of administration – TIW is optimal
• Dosing protocol – increase by 10-20% per treatment
• Max doses – 1500mj/cm2 for face, 3000mj/cm2 for body
• 48 - 72 treatments to determine lack of response
53
PHOTOTHERAPY CONSENSUS
RECOMMENDATIONS
• Monthly tapering after complete repigmentation
• SPT I-III: Yearly follow-up for total body skin exam to
monitor for adverse effects of phototherapy, including
cutaneous malignancy
– Hexsel et al: nonsignificant increase in NMSCs
– Paradisi et al: decreased risk of NMSCs and melanoma
– Teulings et al: no increase in NMSC or melanoma with
phototherapy (questionnaire study)
– No long-term data (only 5-16 yrs)

CHEMICAL LEUKODERMA
• Some household and other commonly used items that can cause a leukoderma
mimicking vitiligo or can exacerbate pre-existing vitiligo
• Consider with confetti vitiligo or contact patterned vitiligo
• Hair dye – avoid hair dyes with para-phenylene diamine
• Deodorant ⁄perfume/detergent/cleansers - make sure they do not contain para-
tertiary butyl phenol
• Rubber sandal /black shoes – minimize use without socks
• Black socks - minimize use due to components of black dye
• Eyeliner – minimize use
56Ghosh S et al. Br J Dermatol. 2009;160:40-7
DEPIGMENTATION
• Removal of remaining skin color in patients with
vitiligo
• Used for patients with vitiligo involving either
>50% of their bodies or resistant involvement of
cosmetically sensitive areas
• The most effective vitiligo treatment (90-95%
complete depigmentation)
• Usually irreversible
• Cultural/psychological considerations

• Can significantly alter appearance
• Unpredictable and progressive
• Most affected are: women, young, darker-complexioned, vitiligo on
exposed sites
• There are some patients for whom no treatment will be effective
• Effective treatments are slow
• Multidisciplinary approach is needed
