RESUMO
Overlap chronic graft-versus-host disease (GVHD) associates both features of acute and chronic GVHD. Trigger factors for chronic GVHD are unclear. We describe two patients who received allogenic haematopoietic stem-cell transplantation, and who later developed overlap chronic GVHD after sun exposure. Available data from in vivo investigations suggest ultraviolet B radiation (UVB) has a beneficial effect on acute and chronic GVHD. The role of sun irradiation as a trigger for isomorphic cutaneous GVHD has been rarely reported in the literature. Herein, we demonstrate for the first time, using repetitive broadband phototesting, that UVB triggers chronic GVHD.

Moderate to severe ichthyosis is known to have a significant impact on quality of life. A French national survey was performed to describe in more detail how ichthyosis impacts the patients' lives. A questionnaire specifically dedicated to ichthyosis was distributed to patients followed in hospital expert centres or members of the French association of patients. A total of 241 questionnaires were completed and returned (response ratio: 29% for children and 71% for adults). A negative impact of ichthyosis was obvious in terms of domestic life (skin care, housework, clothing, etc.), educational/professional lives (rejections by other children, workplace discrimination, absenteeism, etc) and for leisures/sports activities. The patient's economical resources were also heavily impacted by ichthyosis with important out-of-pocket expenses.
