Plain English Summary

Background and study aims
Psoriasis is a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales. Liver damage is thought to be more common in patients with psoriasis based on previous small studies. Several risk factors are associated with liver disease in this group of patients. This includes severity of psoriasis as inflammation has been linked to liver disease. Other risk factors include alcohol intake and obesity. When psoriasis is not controlled with creams, the first systemic medication of choice is methotrexate. There have been concerns that this medication can lead to liver damage or worsen the liver health of psoriasis patients, but currently there is no strong evidence to confirm this. Several tests are currently used by dermatologists to monitor the liver health of patients with psoriasis. These include blood tests to measure liver enzymes. However, these tests are not very accurate at detecting liver damage. Taking a sample directly from the liver is no longer routinely used to diagnose liver damage as it is invasive and has many risks. A non-invasive scan (Fibroscan) similar to an ultrasound can be used to measure how elastic or stiff the liver is. If the liver is stiff this indicates that some damage has occurred. This test is now increasingly used to diagnose liver damage. This study aims to evaluate the extent of liver scarring in patients with psoriasis and assess the relationship between liver scarring and other potential risk factors for liver damage including methotrexate. In addition, the relationship between the outcome of the Fibroscan and other simple tests such as blood tests and scoring systems currently used for monitoring of liver health will be assessed. The overall aim is to use the information gained from this study to determine the number of participants required for a larger study to investigate factors influencing liver damage in this group of patients and to determine whether or not methotrexate is an important contributor to liver damage. Ultimately a risk prediction model will be built to enable dermatologists to predict the risk of liver fibrosis in patients with psoriasis and more accurately assess which patients are suitable to commence and continue treatment with methotrexate.

Who can participate?
Patients aged 18 and over with chronic plaque psoriasis

What does the study involve?
Participants complete questionnaires, provide blood samples (as part of routine care), undergo measurements of weight, waist, height, blood pressure, and undergo an assessment of liver stiffness using a non-invasive test similar to an ultrasound (a Fibroscan).

What are the possible benefits and risks of participating?
It is known that many patients with psoriasis develop liver disease but it is not known why. Participants will have an assessment of their liver health and will contribute to improving the management of psoriatic liver disease in larger populations of psoriasis patients. Methotrexate is a highly effective, generally safe and highly cost-effective treatment option for psoriasis. In the NHS it is the first choice systemic drug for psoriasis. The ability to accurately predict which patients may be at risk from liver scarring would be advantageous. The outcome of this study will inform the design of the larger study to determine which factors can predict the risk of liver scarring and whether or not methotrexate is an important contributor to the risk of liver scarring. The most effective strategies for monitoring the development of liver scarring in this group of patients can then be determined and the result may help in stratification of treatment in this group of patients based on the risk of developing liver scarring.

Scientific titleInvestigation of the prevalence of liver fibrosis in patients with psoriasis using transient elastography and evaluation of the relationship between liver fibrosis and risk factors for liver fibrosis including methotrexate
Study hypothesisThe prevalence of liver fibrosis in patients with psoriasis is high and unexplained. It is hypothesised that important risk factors such as obesity, alcohol and diabetes contribute to the risk of liver fibrosis more than methotrexate.
Ethics approval(s)Approved 17/03/2020, North East - Newcastle & North Tyneside 2 Research Ethics Committee (NHSBT Newcastle Blood Donor Centre, Holland Drive, Newcastle upon Tyne, NE2 4NQ; +44 (0)207 104 8091, +44 (0)207 104 8222; newcastlenorthtyneside2.rec@hra.nhs.uk), REC ref: 20/NE/0039
ConditionLiver fibrosis in psoriasis
InterventionThe study will be a cross-sectional design. Patients with chronic plaque psoriasis diagnosed by a dermatologist with a PASI score of at least 5 at any time will be invited to join the study. A patient information leaflet will be provided. Written consent will be obtained.

Data will be collected via questionnaires, from patient’s medical and electronic records. The majority of the data that the researchers are interested in is recorded as part of standard clinical care and they do not want to repeat measurements unnecessarily. They will therefore accept values for blood tests and imaging that have been recorded within 6 months of recruitment to the study. For patient severity scores and assessments of clinical data such as BMI, these will be collected at the time of recruitment.

The following data will be recorded for each patient:
1. Patient demographics: age, gender, ethnicity socioeconomic status
2. Disease severity: duration of psoriasis, age of onset of psoriasis), year of diagnosis (best approximation), year first seen by a dermatologist, Psoriasis Area and Severity Index (PASI) at recruitment, worst ever PASI, Dermatology life Quality Index (DLQI) at recruitment, worst ever DLQI, family history of psoriasis (first degree relative such as parent, sibling or child)
3. Characteristics: height and weight, Body Mass Index (BMI), Waist circumference, smoking status, alcohol intake questionnaire and AUDIT score, blood pressure, skin type and skin cancer risk factors
4. Liver stiffness measurements: value, >7.9kPa (yes/no), > 7kPa (yes/no), > 9.5kPa (yes/no)
5. Alcohol-related questions: AUDIT score, average alcohol intake in the last year (units per day or units per week)*, a history of sustained excessive alcohol consumption of > 35 units/week for females or > 50 units per week for males for more than 1 year, a history of excessive alcohol consumption (>14 units/day for both) – document the average units/day or week and the duration of alcohol, a history of alcohol dependence
6. Comorbidities – has the patient ever had or required treatment for the following illnesses and year of onset of illness:
cardiac disease (heart failure, cardiac arrhythmias, stroke, coronary artery disorders, angina, myocardial infarction), vascular diseases (hypertension, peripheral vascular disorders, deep vein thrombosis, pulmonary embolism, disorders of metabolism and nutrition (diabetes mellitus, impaired glucose tolerance, dyslipidaemia, endocrine diseases (thyroid disease), nervous system disorders(demyelinating diseases, epilepsy), respiratory, thoracic and mediastinal disorders (asthma, COPD), renal and urinary tract diseases (chronic renal failure), hepatobiliary diseases (viral hepatitis infection, other liver disease), gastrointestinal diseases (peptic ulcer), gastrointestinal inflammatory conditions (Crohn's disease, ulcerative colitis), psychiatric diseases (depression, anxiety), infections and infestations (tuberculosis). immune system disorders, skin and soft tissue disorders (psoriatic arthritis (diagnosis of PSA by a rheumatologist? and year of diagnosis), other types of cancers: skin cancers (non-melanoma skin cancer, squamous cell, carcinoma, basal cell carcinoma) melanoma skin cancers and pre-cancerous skin lesions (melanoma skin cancer, melanoma in situ, Bowen disease, actinic keratosis, keratoacanthoma.
7. Duration on methotrexate in months, cumulative dose of methotrexate
8. UV Therapy– (yes/no), duration and type, response

15. Previous liver ultrasound report, previous liver biopsy report
16. NAFLD and FIB4 score will be calculated and metabolic syndrome will be assessed based on the IDF metabolic syndrome definition (modified version will be used when fasting results not available (fasting glucose will be replaced by HbAIc and HDL cholesterol and triglyceride will be replaced by non-fasting value)
