Psoriasis Epidemiology
• Equal frequency in both genders
• Two peaks of occurrence
– At 20-30 years
– At 50-60 years
• 75% have onset before age 40
Impact of Psoriasis on HRQoL in Germany
• HRQoL measured by the DLQI score
• Psoriasis impacts patient HRQoL
• 34.1% of patients had very large or extremely large impairment of HRQoL (DLQI >10)
DLQI = dermatology life quality index; HRQoL = health-related quality of life.Augustin M, et al. Dermatology. 2008;216:366-372.

Impact of Psoriasis on QoL in the United States
• In a survey of 5,604 patients with psoriasis and psoriatic arthritis conducted between 2003 and 2011 by the NPF1:
– 94% reported that their disease was a problem in their daily life
– 88% reported that it affected their overall emotional well-being
– 82% reported that it interfered with their enjoyment of life
• In a small study of patients presenting with moderate-to-severe psoriasis at the NIH2:
– 82.9% of patients often or always felt the need to hide their psoriasis
– 74.3% claimed that their self-confidence was often or always affected
– 45.7% were often or always depressed
– 82.9% would often or always avoid activities like swimming and sports
– 35.3% were often or always inhibited in their sexual relationships

Impact of Psoriasis on Work Status among US Patients
• Patients with severe psoriasis were more likely to be unemployed than those with mild disease
• 92% of those who were unemployed cited their disease as the sole reason not working
• Of those working, 49% reported missing work due to psoriasis or psoriatic arthritis treatment

US Treatment Trends for Psoriatic Disease
• Biannual survey of patient members with psoriasis and psoriatic arthritis conducted by the NPF, 2003-2011
– Total of 5,604 patients completed the survey
• Phototherapy
– UVB phototherapy was used most frequently, followed by for psoralen–UVA
– Excimer laser was used infrequently
• Oral systemic therapies
– Methotrexate (10%-14.5%), Cyclosporine (0.5%-2%) and Acitretin (1-22.6%)
• Biologic agents
– Proportion of patients receiving etanercept increased from 8.0% in 2003 to 24.5% in 2004 and 25.2% in 2005, and then varied between 11.3% and 19.8% from 2005 to 2009 and 2011
– Gradual increase in adalimumab use was observed from 2008 (8.7%) to 2011 (12.4%)
– Infrequent use (< 5%) of alefacept, infliximab, golimumab, and efalizumab

Psoriatic Arthritis
• An inflammatory musculoskeletal disease associated with psoriasis
• Usually seronegative for rheumatoid factor
• Associated Features
– Spondylitis
– Enthesitis
– Dactylitis
– Iritis
– Mucous membrane ulcers
– Urethritis
– Other extra-articular features of SpA
• Classified as SpA
Psoriatic Arthritis Clinical Patterns
• Distal predominant (Distal inter-phalangeal joints of fingers and toes)
• Oligo-articular (<5 joints) often in an asymmetric distribution
• Poly-articular (≥5 joints), rheumatoid arthritis-like
• Spinal Involvement
• ‘Arthritis Mutilans’
Moll & Wright. Seminars Arthritis Rheum. 1973;32:181.
Psoriatic Arthritis
• Peripheral arthritis
• Axial arthritis
• Peripheral plus Axial
• Patterns change over time
• Early PsA
– 40% oligoarticular
– 60% polyarticular

Variable Definitions for CASPAR Note: STEM: Inflammatory articular disease that may involve joint,
entheseal or axial manifestations is otherwise not defined
• Psoriasis
– Physical evidence of psoriasis: plaque, guttate, nails, scalp, flexural, erythrodermic, pustular.
– Family history of psoriasis: This refers to a first or second-degree relative (child, sibling, parent, grandparent, grandchild, aunt or uncle) reported to have psoriasis by the patient.
– Personal history of psoriasis: Answer 'yes' if any of the listed sources (patient, GP, dermatologist, rheumatologist) are documented to believe the patient has psoriasis or has previously had psoriasis
• Nail dystrophy: onycholysis, pitting, and hyperkeratosis
• Rheumatoid factor: any method, except latex test, ever higher than the upper limit of the reference range for the local laboratory
• Dactylitis: swelling of a whole finger or toe
• Juxta-articular bony proliferation: ill-defined ossification near joint margins, but excluding osteophyte formation

Clinical Predictors of Progression
• Disease Activity
– Number of swollen joints
– Number of tender joints
– Initial ESR
• Damage
– Number of damaged joints
• Tenderness or swelling of a specific joint predicts subsequent damage to that joint
• Digits with dactylitis are more likely to have erosive disease than digits without dactylitis
Bond S, et al. Ann Rheum Dis. 2007;66:370-6. Cresswell L, et al. Ann Rheum Dis. 2011;70:305-8. Brockbank J, et al. Ann Rheum Dis. 2005;64:188-90.
Genetic Markers forProgression of Damage
• Progression of Clinical Damage– HLA-B27 antigen (with HLA-DR7), HLA-B*27 allele
– HLA-B39 antigen, HLA-B*39 allele
– HLA-DQw3 in the absence of HLA-DR7
– KIR2DS1
• Erosive PsA– HLA-DRB1 rheumatoid arthritis ‘shared epitope’
– IL-4 I50V
• Less Progression– HLA-DR7, HLA-DRB1*07
– HLA-B22

Psoriasis
Psoriasis Vulgaris
Unaffected Skin Psoriasis Lesion
Histopathology of Normal Appearing Background Skin and a Psoriasis Plaque (both at same magnification)
2 Defining Parts of the Psoriasis Skin Lesions: Cellular Features
• A change in epidermal growth and differentiation, along with a vascular response that creates plaques on the skin
• An underlying cellular immune response that involves myeloid dendritic cells and T-cells. Cytokines produced by these activated immune cells are key drivers of altered epidermal growth and skin structural changes.
Psoriasis Vulgaris:Clinical Pathological Correlates
• Clinical lesion is characterized by:
A. Indurated plaques
B. Scale
C. Erythema
• Histological correlates are:
A. Regular epidermal hyperplasia with elongated rete (regular acanthosis): increases epidermal thickness
B. Reduced granular layer and keratinocyte maturation with retained nuclei (parakeratosis)
C. Angiogenesis and dilation of superficial venules
Epidermal Reaction in Psoriasis
• Epidermal acanthosis results from excessive proliferation of keratinocytes.
– Demonstrated by an increase in Ki67+ nuclei (next slide) in lesional skin
• Hyperplasia triggers a wound healing differentiation program in the epidermis.
– Visualized by synthesis of keratin 16 in suprabasalkeratinocytes next slide).

Uninvolved Skin (Ki67 protein) Uninvolved Skin (keratin 16)Factors That May Induce Keratinocyte
Hyperplasia in Psoriasis
• Autocrine growth factors, especially EGF family (transforming growth factor-alpha, amphiregulin, and heparin-binding EGF) are all over-expressed in psoriasis
• Kertainocyte growth factor, other FGF family growth factors, and insulin-like growth factor-1 all have increased expression or activity in psoriasis lesions.
• Immune-related cytokines
– IL-1 and IL-6
– IL-10 family: IL-19, IL-20, IL-22, IL-24
Other Changes in the Epidermis
• At a molecular level, hundreds of genes in the epidermis have increased or decreased transcription in active psoriasis lesions
• Some changes reflect cell growth pathways of generalized hyperplasia
• Some changes are more specific to psoriasis—the following slide shows (red) genes with very high expression in psoriasis, but much lower expression in atopic dermatitis, another skin disease that has associated epidermal hyperplasia
S100A9(calgranulin B)
S100A7(psoriasin)
Normal LS Psoriasis
Heatmap Slide
• Genes with high expression in psoriasis lesions all have low expression in non-lesional or normal skin
• As shown by IHC at bottom for S100A7 and S100A9, the altered expression of these genes is created by over-production of corresponding proteins in epidermal keratinocytes
Key Concepts in Pathogenesis
• Genes that are highly and selectively expressed in psoriasis are induced by immune cytokines produced by “polar” T-cell subsets: Th1, Th17, and Th22
• Myeloid dendritic cells (CD11c+ DCs) regulate T-cell activation through antigen-presentation, co-stimulation, and production of cytokines such as IL-12 and IL-23 that drive activation, differentiation and survival of polar T-cell subsets

CD3+ T-cells in Psoriasis
Uninvolved Skin Psoriasis Plaque
T-cell Subsets in Psoriasis
• Th1 (CD4+) and Tc1 (CD8+) T-cells that are defined by synthesis of interferon-gamma upon activation
• Th17 (CD4+) and Tc17 (CD8+), including conventional T-cells and gamma-delta T-cells, synthesize IL-17A and IL-17F upon activation
• Th22 (CD4+) and Tc22 (CD8+) synthesize IL-22 upon activation

Psoriasis Lesion
Th17 T-cells increased in psoriasis lesions. Th1 also increased.
Lowes, et al. J. Invest Dermatol. (2008).
“Polar” cytokines of Th1, Th22, and Th17 T-cells act on epidermal keratinocytes directly to change gene expression profiles and alter other properties of the skin that in the sum create the psoriasis phenotype at clinical, cellular, and molecular levels.
Interferon- binds to receptors that are highly expressed on epidermal keratinocytes. IFN- activates STAT1 and induces expression of many pro-inflammatory gene products

• As shown on the next slide, epidermal thickness (caused by keratinocyte hyperplasia) is increased in reconstructed human epidermis by IL-19, IL-20 and IL-22
• Increased expression of keratin 16, S100A7, and nuclear STAT3 is induced by each of these cytokines, with IL-22 showing the strongest effect

• These inflammatory DCs produce cytokines such asIL-12 and IL-23 that drive polar T-cell differentiation
• IL-23, composed of p19 and p40 subunits, is highlyup-regulated in psoriasis lesions

Genetic Links to IL-23 Axis in Psoriasis
• Chris has a slide that shows general genetic links in psoriasis
• SNPs associated with IL-23 p40 and p19 genes are risk alleles for psoriasis
• The IL-23R also has a risk allele for psoriasis
• Functional studies by Frank Nestle’s group have shown IL-23R risk allele leads to more production of Th17 cells when differentiation is stimulated in vitro from naïve precursors

Blockade of IL-17
• The pathogenic contribution of IL-17 to psoriasis has been determined by antagonizing IL-17A or the IL-17 Receptor A subunit in clinical studies
– IL-17A Antibody Secukinumab/AIN457(Novartis)
– IL-17A Antibody Ixekizumab/LY2439821(Lilly)
– IL-17 Receptor A subunit antibody Brodalumab/AMG827(Amgen)
• All IL-17 antagonists induce a PASI75 response in70%-80% of treated patients after 12 weeks. There isnearly complete reversal of cellular and moleculardisease pathology after IL-17 blockade
Blockade of IL-23
• The pathogenic contribution of IL-23 to psoriasis has been determined by antagonizing the p19 subunit ofIL-23 in clinical studies
– IL23 Antibody Guselkumab (Janssen)
– IL-23 Antibody Tildrakizumab (Merck)
– IL-23 Antibody BI65066 (Boehringer)
• All IL-23 antagonists induce a PASI75 response in70-80% of treated patients after 12 weeks. Productionof IL-17 is strongly attenuated by IL-23 blockade.Effects are similar to IL-17 blockade–there is nearlycomplete reversal of cellular and molecular diseasepathology

• SpA tissues (PsA, AS, USpA):
– More vascularity, neutrophil and CD 163+ macrophage infiltration
• No citrullinated proteins in polyarticular PsA
• DC163+ macrophages, PMN and lining hyperplasia correlated with swollen joint count and acute phase reactants in PsA
• Synovial histopathology of PsA (either oligo or poly) resembles other SpA subtypes more than RA
• Both groups can be differentiated from RA

Differential Dx
• Some conditions which may be difficult to distinguish from Psoriasis
– Seborrheic dermatitis
– Nummular eczema
– Atopic Dermatitis
– Contact dermatitis
– Hand Dermatitis
– Balanitis
– Dermatophyte or Candidal infection
– Palmoplantar keratodermas
– Cutaneous T Cell Lymphoma
– Onychodystrophy related to a number of etiologies including Dermatophyteinfection and trauma
Assessment of Psoriasis: PASI
• Most commonly utilized disease severity measure in clinical trials
• Quantify severity based on:
– Erythema, Induration, and Scale
– Body parts and surface area involved
• Separate calculation for head, trunk, upper extremities, and lower extremities
PASI Strengths
• Assesses both lesion quality and extent of involvement
• Validated instrument – Low intra-observer variability
– Moderate inter-observer variability
– Reproducible when performed by trained individuals
• Allows some historical comparison across several treatments
PASI Limitations
• Erythema, induration, and scaling are equally weighted
• Interpretation not so intuitive
– Nonlinear score
– Composite score has no clinical frame of reference
• Lacks sensitivity to change at lower ranges
• No component for patient input
Seeking Out Your Dermatology Colleague
• When diagnosis of psoriasis is not certain
• Optimization of topical therapies and regimens
• When use of oral retinoid may be appropriate
• When phototherapy may be useful
– Guttate psoriasis, or with diffuse thin plaques
– Adjunctive to systemic therapy
– Poor candidacy for systemic therapy
• When Psoriasis is flaring or unstable
• “Undifferentiated” or seronegative inflammatory disease and a rash
Diagnosis/Presentation of PsA
Features of PsA
• An inflammatory arthritis that occurs in 6%-42% of patients with psoriasis1
• Psoriasis typically precedes development of the arthritic component of PsA
– In 70% of patients with PsA, psoriasis is the first symptom to present2,3
– 20% have PsA before psoriasis2,3
– 10%-15% report simultaneous onset of skin and joint disease2,3
• Severity of psoriasis is not predictive of severity of PsA3

70-80%
10-20%
Assessing the Psoriasis Patient
• Annual assessment for PsA to people with any type of psoriasis. Especially important within the first 10 years of onset of psoriasis.
• Use a validated tool to assess adults for psoriatic arthritis in primary care and specialist settings, such as the Psoriasis Epidemiological Screening Tool (PEST).
– PEST does not detect axial arthritis or inflammatory back pain
• As soon as psoriatic arthritis is suspected, refer to a rheumatologist for assessment and advice about planning their care.

Identifying PsA
• Dermatology
– Recognize relevant MSKL sxs among Pso pts
– CASPAR may not yet be applicable without a definition of inflammatory arthritis
• Rheumatology
– Distinguish inflammatory and non-inflammatory disease
– Identify PsA within inflammatory arthritis
– CASPAR criteria applicable to all patients

– Swollen joints
– Enthesitis
– Low back / buttock pain
Screening Tools for PsA
• Most people have psoriasis before joint symptoms
• Is there a simple screening test for PsA?– Quick and easy
– Patient completed
– Sensitive
– Reasonably specific
• Patient-completed questionnaires– PAQ (1997) and modified PAQ (2002)
– PASE (2007)
– ToPAS (2008)
– PEST (2008)
– PASQ (2009)
PAQ = Psoriasis and Arthritis Questionnaire; PASE = Psoriatic Arthritis Screening and Evaluation. ToPAS = Toronto Psoriatic Arthritis Screen; PEST = Psoriasis Epidemiology Screening Tool. PASQ =Psoriatic Arthritis Screening Questionnaire.
PASE – Symptoms
• I feel tired for most of the day
• My joints hurt
• My back hurts
• My joints become swollen
• My joints feel ‘hot’
• Occasionally, my entire finger or toe becomes swollen, making it look like a ‘sausage’
• I have noticed that the pain in my joints moves from one joint to another, for example, my wrist will hurt for a few days, then my knee will hurt, and so on

MDA Criteria for PsA
• A patient is classified as in MDA when they meet 5 of 7 of the following criteria:
– tender joint count ≤1
– swollen joint count ≤1
– PASI ≤1 or BSA ≤3
– patient pain VAS ≤15
– patient global activity VAS ≤20
– HAQ ≤0.5
– tender entheseal points ≤1

Comorbidity in Psoriasis andPsoriatic Arthritis: General Principles
• Most comorbidity research focuses on psoriasis – can be challenging to determine how Pso and PsA individually contribute to co-morbidity
• Severity and clinical presentations of both diseases can be highly variable and risk of comorbidity is likely related to severity of disease, especially for cutaneous disease
Important Differences between Pso and PsA That May Impact Co-Morbidity Risk
Psoriasis Psoriatic Arthritis
TreatmentLess likely to use DMARDs
More likely to use DMARDs
Oral steroids Generally avoidedUsed commonly and often chronically
Most Common Gene Defect
HLA-Cw6 HLA-B27 (axial disease)
Systemic inflammation as measured by CRP
Frequency
Mild disease is common – small associations of limited significance may be seen
Statistically rare-important associations may be missed due to statistical power
CV = cardiovascular.1. Azfar RS, Gelfand JM. Curr Opin Rheum. 2008;20:416-422. 2. Mehta NN, et al. EurHeart J. 2010;31:1000-1006.
Psoriasis and Co-Morbidities Paradigm
Mediating factors1
• Pathophysiology– Th1/17 inflammation (atherosclerosis, thrombosis, lipid metabolism)– Epidermal proliferation (↑uric acid, oxidative stress)– Angiogenesis (endothelial dysfunction)
• Treatment– Increase CV risk (e.g. cyclosporine, acitretin)?– Decrease CV risk (e.g. methotrexate)?
• Psychosocial impact – Depression, alcohol and smoking, lower socioeconomic status

Does Treatment of PsoriasisLower CV Events?
• VA cohort: Low-dose methotrexate is associated with lower risk of vascular disease compared to patients not receiving methotrexate (RR: 0.50, 95% CI 0.31–0.79)1
• Kaiser cohort: Lower rate of MI in TNF inhibitor vs. topical (HR: 0.50, 95% CI 0.32–0.81) and in methotrexate vs. topical (HR: 0.52, 95% CI 0.31–0.85)2
• Danish cohort: Lower rate of death, MI, stroke in patients treated with biologic (HR: 0.28, 95% CI 0.12–0.64) and methotrexate (HR: 0.50, 95% CI 0.26–0.97) compared to other therapies (cyclosporine, phototherapy, acitretin)3
• Taiwan claims data: No effect of methotrexate compared to treatment with retinoids, cyclosporine, azathioprine, mycophenolate (HR 0.97, 95% CI 0.79–1.19)4
• Meta-analysis of RCTs: TNF inhibitors and IL-12/23 inhibitors show no benefit on major CV events and IL-12/23 inhibitors possibly show harm5
• US claims data: HR 1.33 (95% CI 0.90–1.96) of methotrexate, cyclosporine, alefacept, efalizumab, adalimumab, etanercept and infliximab compared to phototherapy6

Clinical Implications: Elevated Cardiovascular Risk in Psoriatic Disease
Standard Screening Recommendations
• Hypertension
– Every 2 year if BP <120/80 mm Hg
– Every year if BP 120 to 139/80 to 89 mm Hg.
• Diabetes (Fasting plasma glucose, HbA1c, or OGTT)
– Adults ≥ 45
– Adults BMI ≥25kg/m2 who have one or more additional RFs
– Repeat every 3 years
• Cardiovascular risk assessment:
– Traditional risk factors every 4-6 years in patients 20-79
– Estimate 10 year risk in those 40 -79

Major Recommendations for Statin Therapy for ASCVD Prevention
Statin Benefit Groups
1. Clinical ASCVD
2. LDL-C>190 mg/dl
3. Age 40-75 with DM and LDL-C 70-=189 mg/dl without ASCVD
4. Age 40-75 with LDL-C 70-189 mg/dL and have 10 year ASCVD ≥ 7.5%
Definitions of High- andModerate-Intensity
Statin Therapy
ASCVD Statin Benefit GroupsHeart healthy lifestyle habits are the foundation of ASCVD prevention.
In individuals not receiving cholesterol-lowering drug therapy, recalculate estimated10-y ASCVD risk every 4-6 y in individuals aged 40-75 y without clinical ASCVD
or diabetes and with LDL-C 70-189 mg/dL.
ASCVD Prevention Benefit of Statin Therapy may be less clear in other groupsIn selected individuals, consider additional factors influencing ASCVD risk and
potential ACSVD risk benefits and adverse effects, drug-drug interactions,and patient preferences for statin treatment.

Obesity, Diabetes, Metabolic Syndromeand Psoriasis: Clinical Implications
• Recommend maintenance of normal body weight in those at greatest risk of developing psoriasis (e.g. + FH)
• Screening for diabetes and lipid disorders in patients with psoriasis, particularly when severe
– Fasting plasma glucose ≥ 126 mg/dl or HbA1c ≥ 6.5% or random glucose > 200 mg/dl in symptomatic patients
– Pre-diabetes fasting glucose 100-125 mg/dl, HbA1c5.7%-6.4%.
Inzucchi SE. Diagnosis of Diabetes. NEJM. 2012;367:542-550.
Obesity, Diabetes, Metabolic Syndromeand Psoriasis: Clinical Implications
• Altered risk/benefit profile of treatment– Decrease efficacy of non-weight based treatments
– Methotrexate: more aggressive monitoring with liver biopsies
*Methotrexate toxicity is associated with a history of total lifetime alcohol intake before methotrexate therapy. The exact amount of alcohol that confers risk is unknown and differs among persons.Kalb RE, et al. JAAD. 2009;60:824-37.
Risk Factors for Hepatic Toxicity from Methotrexate
• History of or current alcohol consumption*
• Persistent abnormal liver chemistry studies
• History of liver disease, including chronic hepatitis B or C
• Family history of inheritable liver disease
• Diabetes mellitus
• Obesity
• History of significant exposure to hepatotoxic drugs or chemicals
• Lack of folate supplementation
• Hyperlipidemia
Monitoring for Hepatotoxicity in High-Risk Patients
• Consider the use of a different systemic agent
• Consider delayed baseline liver biopsy (after 2 to 6 months of therapy to establish medication efficacy and tolerability)
• Repeat liver biopsies after approximately 1.0 to 1.5 g of therapy
Smoking and Psoriatic Disease
• Smoking may be a risk factor for psoriasis1
– Rationale – Nicotine activates dendritic cells, T cells, and Th-1 cytokines
• Heavy smoking associated with more severe psoriasis2
• Among psoriasis patients smoking may be associated with a decreased risk of PsA3
• Smoking associated with worse PsA symptoms and poorer response to TNF inhibitors4

Alcohol and Psoriasis
• Excess alcohol intake associated with:
– Psoriasis, particularly in males
– More severe psoriasis
– Treatment noncompliance
Kurd, et al. Expert Rev Clin Immunol. 2007;3:171-185.
5/28/2015
6
Clinical Implications:Psoriasis and Smoking/Alcohol
• Smoking
– Cessation particularly for those with pustular disease
– Smoking avoidance in people at risk for psoriasis (e.g. + FH)
– Annual low dose CT screening for 55-80 with 30 pack year history and current smoker or quit within 15 years
• Alcohol
– A marker for treatment failure/non-compliance
– Alcohol use alters risk/benefit profile of treatments
– Example: RCT demonstrates that etanercept increases risk of all cause mortality and serious infections in patients with moderate to severe alcoholic hepatitis
Boetticher NC, et al. Gastroenterology. 2008;135:1953-1960. Moyer VA, et al. Screening for lung cancer: US Preventative Services Task Force recommendation statement. Ann Internal Med. doi:10.7326/M13-2771.
Cancer and Psoriasis
• Cancer is of concern due to chronic use of immunosuppressive therapies, co-morbid behaviors, and chronic inflammation
• Patients with severe psoriasis 41% more likely to die of cancer (4th highest excess risk)
• Cancer of lung, liver, pancreas, breast, colon, bladder, and kidney have been inconsistently associated with psoriasis
• Lymphoma has been of special concern
Neimann, et al. Expert Review of Dermatology. 2006;1:63-75. Abuabara K, et al. British Journal of Derm. 2010; PMID: 20633008.
Clinical Implications: Psoriasis and Lymphoma
Consider biopsy in severe disease, treatment failures
CTCL may progress rapidly with immuno-suppression
Clinical Implications
• Biopsy patients with atypical features of psoriasis and/or those not responding to treatment
• Encourage patients to stay up to date on age appropriate cancer screening
– Cervical cancer: Pap smear (q 2-3 yrs ages 21-65)
– Breast cancer: mammography (50-74, q 2 yrs)
– Colon cancer: (50-75) fecal occult blood q year, flex sig q5 yrs, colonoscopy q10 yrs)
– Lung cancer: Annual low dose CT screening for 55-80 with ≥30 pack year history and current smoker or quit within 15 years
• Large, long-term follow up studies necessary to determine risk of cancer with psoriasis treatments
CDC guidance accessed 1/21/14 Note: Earlier Screening recommended in those at high risk.Moyer VA, et al. Screening for lung cancer: US Preventative Services Task Forcerecommendation statement. Ann Internal Med. doi:10.7326/M13-2771.
77 Year Old Male, 20+ Years of Psoriasis, Current 30+ Pack Year Smoker Infection and Psoriasis
• Streptococcal pharyngitis a risk factor for guttatepsoriasis
– Molecular mimicry of streptococcal M peptides and human keratins
• HIV a risk factor for severe psoriasis
– HIV may act as superantigen in the activation of T cells
• Patients with severe psoriasis 65% more likely to die of infection (second highest excess risk)
Abuabara K, Azfar RS, Shin DB, Neimann AL, Troxel AB, and Gelfand JM: Cause-specific mortality in patients with severe psoriasis: A population-based cohort study in the United Kingdom. British Journal of Dermatology. 163(3): 449, September 2010.

Clinical Implications: Psoriasis and Infection
• Screen for Streptococcal infection with guttate flares
• Screen for HIV in severe psoriasis
• Vaccination for
– influenza (annually)
– pneumonia (PCV13 and PPSV23)
– zoster (age ≥60)
• Live vaccine – not recommended while on immune suppression

IBD
Extra Dermal andExtra-Articular Manifestations
Immune Mechanisms Shared between IBD and SpA
• Genetic susceptibility
• Aberant recognition of self
• Autoantibodies against specific antigens shared by the colon and other extra-colonic tissues
• Increased intestinal permeability
• Microbiome
• Infection
Articular involvement in IBD Prevalence: 16-33%
GI tract involvement in SpAPrevalence: 70%Long-term: 7-12% SpA will develop overt IBD
Lymphocyte recirculationMigration pathway altered by adhesion molecules and chemokines
Intestinal lymphocytes traffic to joints
Activated intestinal lymphocytes in IBD patients adhere to inflamed synovial tissues via adhesion molecules like VAP-1
NOD2/CARD 15/IBD1 mutationsLink to CD and SpA bowel inflammation and isolated sacroiliitis
HLA-B2750-78% of IBD patients with AS are HLA-B27+

Non-Biologic Therapies for Psoriasis
• Keratolytics– Salicylic Acid, Urea
• Corticosteroids
• Vit D Analogs– Calipotriene
• Calcineurin inhibitors– Tacrolimus
• Topical Retinoids– Tazarotene
• Tars– Goeckerman Technique
– Ingram Technique
• Anthralins– Dihydroxyanthralin
• UV Light– UVA +/- psoralen, UVB, narrow
band UVB
• 311nm laser device
• Methotrexate
• Cyclosporine
• Acitretin
• Emerging Therapies
Topical Treatments for Psoriasis
Topical Therapies
• Most commonly prescribed form of treatment
• Frequently used in combination with other topicals and with systemic therapies
• Several options
– Over the counter (OTC)
– Prescription
• Typically applied once or twice a day, each
• Vehicle matters
– effect, side effect
– creams, ointments, lotions, solutions, foams, gels, shampoos, and baths
Keratolytics
• Help to debride scale and allow other medications to penetrate better.
• Urea 20%-80% cream and gel
• Sal Acid: 3-5% in cold cream or hydrophilic ointments
– Rare: salicylate toxicity with tinnitus, confusion, refractory hypoglycemia, esp in Pts with diabetes or renal disease.
Corticosteroids
• Suprapotent (Class I) Corticosteroids for body and extremities
• Low potency for body folds and face
• Pick one in each class and remember it!
– Class 1: clobetasol, halobetasol
– Class 6: desonide, hydrocortisone
• Consideration of vehicle
• Rotational or alternating therapy to minimize AEs
Vitamin D Analog
• Calcipotriene 0.005% or Calcitriol
– Vitamin D3 analog that regulates KC differentiation
– Available as cream, ointment or solution
– Ointment form works best
– Should be applied 2x/day to be effective
– May be irritating to unaffected skin
– Often used in combination/rotation with a topical steroid
• Also comes branded in combination with betamethasone dipropionate
5/28/2015
3
Calcineurin inhibitors
• Tacrolimus 0.03%, 0.1% ointment; Pimecrolimus 1% cream
– Inhibits T-cell activation by inhibiting the synthesis and release of cytokines (IL-2) from T-cells.
– Ointment vehicle works best
– Better on thin skin areas (ie face, groin)
– Should be applied 2x/day to be effective
– May cause local irritation
– May be in rotation with a topical steroid
Retinoids
• Tazarotene 0.05%, 0.1% cream and gel
– Vitamin A derivative that binds retinoic acid receptors (RAR β and RAR γ)
– Modulates KC differentiation and proliferation, and suppresses inflammation
– Local irritation is treatment limiting
Phototherapy
Phototherapy
• Light unit directing ultraviolet light in specific wavelengths to affected areas
• Proposed mechanisms:
– Alterations in cytokine expression with suppression of Th1/Th17 inflammatory axis
– Apoptosis of several cell types in the skin
• Activated T cells in epidermis and dermis, Keratinocytes, and to a lesser degree Langerhans cells
– Suppression of Langerhans cell function
• Present day utilization: nbUVB >>> PUVA
Wong, et al. J Cutan Med Surg. 2013 Jan-Feb; 17(1): 6-12.
Phototherapy
• Narrow Band Ultraviolet B (NBUVB)
– Most efficacious for thin plaque psoriasis and especially guttate psoriasis
– Monotherapy or in combination with topical or systemic treatments
– Administered 2-3 times week. Patients may clear in 25-30 treatments.
– Requires maintenance treatments to retain efficacy
– Less carcinogenic than broad band UVB and UVA
– Copay and Time Lost are barriers
Laser Device Therapy
• 311 nm device
– Hand-held lasers emits a focused wavelength of light
– Best for treating individual plaques and small areas
– May not be widely available
– Well tolerated with low risk

Non-Biologic Systemic Medications
for Psoriasis
Methotrexate
• Exact MOA of MTX for inflammatory disease is complex.
• MTX transported into variety of cells
• Intracellular glutamation
• MTXGlun inhibition of key enzymes in the folate pathway
• Inhibition and accumulation of AICAR and ATIC nucleotides increased adenosine into circulation.
• Extracellular adenosine increased cAMP
• cAMP inhibits production of pro-inflammatory cytokines (TNF-α, IFN-γand IL-1β)
Montesinos, et al. Adenosine A2A or A3 receptors are required for inhibition of inflammation by methotrexate and its analogue MX-68. Arthritis Rheum. 2003, 48:240-247.Ochaion, et al. Methotrexate enhances the anti-inflammatory effect of CF101 via up-regulation of the A3 adenosine receptor expression. Arthritis Res Ther. 2006,8:R169.
Methotrexate
• Dose: 10-25 mg weekly + folic acid 1mg daily
• PASI 75 achieved in 35-42%
• AEs: GI upset, oral ulcers, hair shedding, fatigue >>> marrow suppression, hepatic fibrosis, pulmonary fibrosis
• Pregnancy category: X

Liver Biopsy?
Cyclosporine
• CSA 5 mg/kg/day yielded PAS75 response in 50 to 97% of patients
• CSA 2.5 mg/kg/day yielded PASI 75 response in 28 to 85%.
• Remission could be maintained at CSA dose of at least 3mg/kg/day More than 50% of patients treated with CSA may have an increase in serum creatinin value >30% of baseline if treatment is prolonged for 2 years.
• CSA 2.5 mg/kg/day effective in 89% of patients with palmoplantarpustulosis.
• CSA 3 to 5 mg/kg/day yielded a significant improvement in >50% of patients with erythrodermic psoriasis
Maza, et al. JEADV. 2011, 25 (Suppl. 2), 19-27.
Acitretin
• Dose: 10-50mg daily
• Oral retinoid that slows KC proliferation and stimulates differentiation
• Interferes with intracellular metabolism of natural retinoids. Competes with retinoic acid for CRABP binding and activates retinoic acid nuclear receptors
• Teratogen. Not given to women of child bearing age.
• Etretinate formed when acitretin used with ethanol.
– Detected in 100% patients with an average weekly consumption of >200g ethanol (15 pints of beer)

EULAR PsA Management Recomendations: Use of Synthetic DMARDs in PsA
• Patients with active PsA and a potentially poor prognosis should be started on DMARDs
– According to the EULAR guidelines for management of PsA, methotrexate (MTX) is the first choice synthetic DMARD for PsA
– Synthetic DMARDs do not appear to be effective for the treatment of enthesitis and axial disease
– None of the synthetic DMARDs have demonstrated efficacy for limiting structural damage in PsA
Gossec L, et al. Ann Rheum Dis. 2012;71:4-12.
Steroid Injections
• Sacroiliac and peri-sacroiliac steroid injections appear beneficial in small randomized trials.
• Steroid injection of inflamed peripheral joints may be beneficial
Traditional PsA Therapy
• Nonsteroidal anti-inflammatory drugs
• Corticosteroids
• DMARDs
– Sulfasalazine
– Methotrexate
– Leflunomide
– Cyclosporine
– Antimalarials

Emerging Biologic Therapies for PsA
• IL12-23i
– Ustekinumab highly effective in psoriasis, modest in PsA
– Briakinumab – discontinued because of CV safety concerns
• IL-17i
– Importance of IL23R and TH17 cell in PsA
– Outstanding efficacy in psoriasis, data in PsA emerging
• IL-6 and IL-6Ri
– IL-6 richly expressed in psoriasis plaques and PsA synovium
– Background concern about potential for LFT/lipid increase
– May be used as monotherapy without background MTX
– Plus/minus effectiveness of tociliumab in PsA case reports
– Data from Phase 2 trial of clazakizumab in PsA pending

Conclusions
• Biologic therapy has revolutionized the treatment of psoriasis and PsA
• Achievement of remission or low disease activity is now achievable
• For patients who don’t achieve adequate efficacy, lose efficacy, or cannot tolerate med, switching in class or different MOA can occur
• Safety is an issue and close monitoring is necessary
Post-Activity Question 1
How confident are you in using biologic therapy to achieve remission or low disease activity psoriasis?
1. Very confident
2. Confident
3. Somewhat confident
4. Not confident
Post-Activity Question 2
How confident are you in using biologic therapy to achieve remission or low disease activity in PsA?
1. Very confident
2. Confident
3. Somewhat confident
4. Not confident
Post-Activity Question 3
For patients who do not achieve adequate efficacy, I plan to:
1. Switch in class
2. Switch to a different MOA
3. Give the current therapy more time
4. Add-on another therapy
