International Rare Histiocytic Disorders Registry (IRHDR)

Обзор

The rare histiocytic disorders (RHDs) are characterized by the infiltration of one or more organs by non-LCH histiocytes. They can range from localized disease that resolves spontaneously, to progressive disseminated forms that can be sometimes life-threatening. Since they are extremely rare, there is limited understanding of their causes and best treatment options. Physicians, patients and parents of children with RHDs frequently consult members of the Histiocyte Society regarding the best management of these disorders. Very often, no specific recommendation can be made due to the lack of prospective outcome data, or even large retrospective case series. The creation of an international rare histiocytic disorders registry (IRHDR) could facilitate a uniform diagnosis of the RHDs, as well as the collection and analysis of the clinical, epidemiological, treatment and survival data of patients with RHD. The registry may also lead to future therapeutic recommendations, provide a framework for future clinical trials and create excellent research opportunities.

Подробное описание

Histiocytoses are rare diseases caused by an excess of cells called Histiocytes, which can infiltrate the skin, bones, lungs, liver, spleen and the central nervous system. These disorders can range from localized involvement that resolves spontaneously, to progressive disseminated forms that can be debilitating and sometimes life-threatening. The rare histiocytic disorders (RHD), or non-Langerhans cell disorders, are a diverse group of disorders defined by the accumulation of histiocytes that do not meet the criteria for Langerhans cell histiocytosis (LCH) or hemophagocytic lymphohistiocytosis (HLH). They include: Juvenile xanthogranuloma family, Erdheim-Chester disease, Multifocal Reticulohistiocytosis, Rosai-Dorfman disease and the Malignant Histiocytoses. Since they are so rare, there is limited understanding of their causes and treatments. Physicians, patients and parents of children with rare histiocytoses frequently consult members of the Histiocyte Society on the management of these disorders. Very often, no specific recommendation about treatment can be made due to the lack of prospective outcome data for these rare entities. The creation of an International Rare Histiocytic Disorders Registry (IRHDR) will facilitate a uniform diagnosis of the RHD's, as well as the collection and analysis of the clinical, epidemiological, treatment and survival data of patients with RHD. The registry will also provide expert pathology reviews and may lead to future therapeutic recommendations. Furthermore, the IRHDR can provide a framework for future clinical trials, thus, creating excellent research opportunities. Lastly, a de-identified link between clinical data and companion biology studies can potentially be accomplished in the future through the IRHDR. This may further help in understanding the etiology of these rare diseases, as well as identifying potential therapeutic targets.

Вмешательства

• Другое Registry study
  No intervention.

Первичные конечные точки

• Collecting data on disease presentation, treatments used and treatment outcomes over time for patients diagnosed with RHD to better understand the diseases and optimize the treatments. [Срок оценки: Data will be analysed on average yearly, the registry will be ongoing for 10 years.]

Вторичные конечные точки (1)

• Develop treatment guidelines for the RHD based on solid clinical trial data. [Срок оценки: Data will be analysed on average yearly, the registry will be ongoing for 10 years.]
