Depletion, UV Exposure and Relation between Ozone and Skin Cancer

Grantee: Dr. Harry Slaper, Laboratory for Radiation Research, RIVM, Holland

Amount: DKK 200,000

Grant category: Research Grants in open competition

Year: 2012

Geography: Netherlands

Dr. Harry Slaper, Laboratory for Radiation Research, RIVM, Holland, has developed a unique model, the AMOUR 2.0, for relating ozone depletion scenarios and UV to changes in skin cancer incidence (melanoma, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC)). This model has been used since 2008 as a reference for other researchers in Europe.

The model, however, does not factor in age. Apart from cumulated UV Radiation, age is the major risk factor for the development of Non Melanoma Skin Cancer (NMSC), and an ageing population will contribute to the increasing incidence of NMSCs.

The LEO Foundation has funded a development of the model to also incorporate the effects of population aging in Europe in order to obtain a more precise picture of the projected incidence of NMSC in Europe.

Based on the Dutch Cancer registry and the enhanced model, then, Dr. Slaper has estimated age and gender specific incidence rates, incorporated them into the model as well as UN Population forecasts to forecast the incidence of NMSC in Europe and the contribution of both cumulated UV radiation and age and gender.

The results are expected to play a key role in raising awareness among decision makers in the health care sector on the increasing incidences of non-melanoma skin cancer, an awareness which will also benefit patients as the long-term aim is to increase the political prioritisation of non-melanoma skin cancer.

Phenotyping itch in atopic eczema and psoriasis patients

Grantee: Dr Gil Yosipovitch, MD, Professor of the Department of Dermatology at Wake Forest School of Medicine, Winston-Salem, North Carolina

Amount: EUR 264,874

Grant category: Research Grants in open competition

Year: 2012

Geography: USA

The LEO Foundation is supporting another project that investigates
itching and may also pave the way for new anti-itch treatments.

The study is led by Dr Gil Yosipovitch, MD, Professor of the Department of Dermatology at Wake Forest School of Medicine, Winston-Salem, North Carolina, USA, and seeks to investigate aspects of itching in patients with atopic dermatitis and psoriasis.

Itching affects millions of people worldwide and represents a significant medical challenge as no mechanism-specific treatments are currently available. The genetic aspects of itching in chronic pruritic conditions such as atopic dermatitis and psoriasis are also rather under-investigated.

Dr Gil Yosipovitch will examine the expression of genes, neuropeptides and other itch-specific mediators specifically implicated in atopic dermatitis and psoriasis in comparison to healthy controls.

The exploration of this area may hold good news for patients, as the findings may be useful in developing new anti-itch treatments.

Psoriasis and cardiovascular co-morbidity – funding of an overview committee

Grantee: Professor Christopher Griffiths, Faculty of Medical and Human Sciences, University of Manchester

Amount: DKK 900,000

Grant category: Research Grants in open competition

Year: 2012

Geography: United Kingdom

The background to this project – establishing and operating a multidisciplinary international scientific committee on psoriasis and cardiovascular disease (CVD) – is the increased risk of cardiovascular disease and related mortality amongst psoriasis patients.

Research investigating the interface between the two conditions – from epidemiological studies to basic experimental research – may prove key to improving the overall care of psoriasis patients.

Chaired by Professor Christopher Griffiths from the Faculty of Medical and Human Sciences at the University of Manchester in the UK, the committee consists of three dermatologists and three cardiologists, with at least one of each based in the USA.

The committee’s work focuses on:

  • How scientific understanding can be improved through new research initiatives
  • Building a consensus on biomarkers in research
  • The potential relationships between biomarkers and clinical results and the benefits for patients
  • Areas of particular interest for further research
  • Investigation of cardiovascular side-effects in clinical development projects

Psoriasis and cardiovascular co-morbidity – epidemiological and experimental studies

Grantee: Dr Peter Riis Hansen, Department of Cardiology P, Gentofte Hospital

Amount: DKK 4,200,000

Grant category: Research Grants in open competition

Year: 2012

Geography: Denmark

Psoriasis patients have increased risk of cardiovascular disease (CVD), which still carries high morbidity and mortality in western societies, and is increasing dramatically in the emerging economies.

Consequently, research directed at the interface between psoriasis and CVD, from the level of epidemiological studies to basic experimental research, is of paramount importance in order to improve overall care for psoriasis patients, as well as supporting the need to seek help to receive treatment.

A research project led by Dr Peter Riis Hansen, Gentofte Hospital, Department of Cardiology P, Denmark, will help to:

  • Inform and motivate dermatologists to play a pivotal role in screening and helping patients with psoriasis to prevent an increased risk of CVD
  • Motivate patients with psoriasis to, firstly, seek treatment and assessment of their CVD risk and, secondly, improve treatment of psoriasis to reduce the overall immune activation
  • Establish a murine model of psoriasis and CVD that is suitable for mechanistic studies and preclinical drug evaluation
  • Identify new markers of psoriasis and/or CVD activity that may be relevant for clinical use.

Epidemiology of eczema disease in Denmark

Grantee: Professor Torkil Menné and Professor Jeanne Duus Johansen, Gentofte Hospital

Amount: DKK 2,828,000

Grant category: Research Grants in open competition

Year: 2012

Geography: Denmark

The project involves several research groups at Gentofte Hospital in Copenhagen and is headed by Professor Torkil Menné and Professor Jeanne Duus Johansen.

The work aims to shed more light on the incidence of eczema in the general population and pave the way for improved prevention and treatment.

Eczema is the most prevalent of the skin disorders. It is not only one of the most common childhood diseases, but also a typical occupational disease, making it one of the most widespread diseases in the overall population. Eczema also results in substantial costs and loss of quality of life for patients.

Despite the disease prevalence, there is a shortage of data and research on eczema in the general population.

This project, which draws on a number of databases and disease registries unique to Denmark, aims to produce a detailed picture of the clinical and sociodemographic aspects of eczema in both the general population and the patient population.

Its specific aims are:

  • To describe the consequences of eczema in terms of health care, education and employment, and the development of co-morbidities
  • To explore the genetics behind eczema and its
    consequences.
