Primary Cause of Death in Dyskeratosis Congenita
Understanding the Mortality Landscape
- Bone marrow failure represents the principal cause of premature mortality in patients with dyskeratosis congenita, occurring as the natural progression of the disease 1, 2
- Pulmonary complications, particularly pulmonary fibrosis, emerge as a major cause of death, especially in late adolescence or early adulthood 1, 2
- Malignant transformation contributes to mortality, with increased risk of myelodysplastic syndrome, leukemia, and head and neck squamous cell carcinoma 2
Clinical Context and Pathophysiology
- All patients with dyskeratosis congenita have telomeres below the first percentile for age, leading to progressive hematopoietic failure 1, 2
- The bone marrow failure typically manifests as progressive pancytopenia affecting multiple cell lines 2, 3
- This creates vulnerability to life-threatening infections and bleeding complications even before other organ systems become critically affected 2, 3
