Alpha-1 Antitrypsin Deficiency: Principles of Care.

Abstract:

:Alpha-1 antitrypsin deficiency is an autosomal co-dominant inherited disorder that results in decreased circulating levels of alpha-1 antitrypsin (also known as alpha-1 proteinase inhibitor) and predisposes affected individuals to early onset lung and liver disease. There is currently no cure for alpha-1 antitrypsin deficiency. However, appropriate treatment and a high standard of clinical care can prevent patients from being seriously affected and having to undergo major medical interventions, such as organ transplantation. Beyond managing the symptoms associated with alpha-1 antitrypsin deficiency, alpha-1 proteinase inhibitor therapy is the only treatment for the condition's underlying cause. Early diagnosis is important to ensure efficient therapeutic strategies and to minimize further deterioration of lung function. alpha-1 antitrypsin deficiency is under diagnosed globally, partly because the disease has no unique presenting symptoms. This document was prepared by a Portuguese multidisciplinary group and it aims to set out comprehensive principles of care for Alpha-1 antitrypsin deficiency. These include the importance of registries, the need for clinical research, the need for consistent recommendations (regarding diagnosis, treatment and monitoring), the role of reference centres, the requirement for sustained access to treatment, diagnostic and support services, and the role of patient organizations. :A deficiência de alfa-1 antitripsina é uma doença hereditária autossómica co-dominante que resulta numa diminuição dos níveis plasmáticos de alfa-1 antitripsina (também conhecida por inibidor da alfa-1 proteinase) e predispõe os indivíduos afetados ao desenvolvimento de doença pulmonar e hepática precoce. Atualmente não existe cura para a deficiência de alfa-1 antitripsina. No entanto, o tratamento adequado e um elevado padrão de cuidados clínicos podem prevenir que os doentes sejam gravemente afetados e terem que se submeter a intervenções médicas major, como o transplante de órgão. Para além de atuar nos sintomas associados à deficiência de alfa-1 antitripsina, a terapêutica com o inibidor da alfa-1 proteinase é o único tratamento disponível que atua na causa subjacente desta patologia. O diagnostico precoce é importante para assegurar a implementação de estratégias terapêuticas eficientes e para minimizar a destruição adicional da função pulmonar. A deficiência de alfa-1 antitripsina está globalmente sub diagnosticada, em parte devido ao fato desta doença não apresentar sintomas únicos. Este documento foi preparado por um grupo multidisciplinar e visa estabelecer princípios de cuidados abrangentes para a deficiência de alfa-1 antitripsina. Estes incluem a importância dos registros, a necessidade de investigação clinica, a necessidade de recomendações consistentes (no que diz respeito ao diagnostico, tratamento e monitorização), o papel dos centros de referência, a necessidade de acesso sustentado ao tratamento, diagnostico e serviços de suporte, e o papel das associações de doentes.
