Liver and Cardiac Involvement in Shwachman-Diamond Syndrome: A Literature Review.

Shwachman-Diamond syndrome (SDS) is an autosomal recessive inherited disease of the SBDS gene. It has multi-organ involvement but primarily affects the bone marrow and the pancreas. This disease is more commonly found in males than females, and its earliest manifestation in infancy is pancytopenia, most especially neutropenia. Our article attempts an in-depth analysis of the hepatic and cardiac association in this disease and the severity of this association. For the purpose of this study, we engaged in an in-depth research of critically appraised literature and published articles. We searched for such articles on PubMed and Google Scholar using regular and Medical Subject Headings (MeSH) keywords. We eventually selected 32 articles from the search results and carefully read through and analyzed them. These articles showed the usual age of diagnosis of SDS to be at infancy (before age one), with a predominantly median survival age of 35 years. All the published articles we reviewed showed some hepatic and cardiac associations with SDS, but the extent of the associations varied. Even though most hepatic involvements were found to be benign, some severe cases led to fibrosis and hepatic failure. Although there is no particular consensus as to the exact outcome of cardiac involvement, the few cases we reviewed showed that cardiac association could be a severe complication and could even be fatal. Most of the cases reported in the literature had been diagnosed at autopsy.
