I have never heard of Cystic Fibrosis Related Diabetes (CFRD), but I have heard of Latent Autoimmune Diabetes in Adults (LADA, sometimes called Type 1.5). It's an autoimmune type of diabetes (like type 1), but it doesn't start showing symptoms until adulthood (typically middle age or later, but I know of one case that manifested in early 20s). It is often mis-diagnosed as type 2, because of the later onset, but patients often become insulin dependent.
