1.Hereditary Pancreatitis.
The Korean Journal of Gastroenterology 2005;46(5):358-367
The first family of hereditary pancreatitis was described in 1952. The mode of inheritance is autosomal dominant trait with an 80% of penetrance rate. Although hereditary pancreatitis is rare, this disorder has provided valuable insights in understanding the pathophysiology of pancreatitis and pancreatic cancer. The causative gene of hereditary pancreatitis was identified in 1996 through mutational analysis of genes within chromosome 7q35. Most forms of hereditary pancreatitis are caused by one of two common mutations, R122H in the third exon or N29I in the second exon of the cationic trypsinogen gene (protease serine 1, PRSS1). R122H mutation is the most common PRSS1 mutation. Additional mutations of the cationic trypsinogen gene have been described. In Korea, first family of hereditary pancreatitis with cationic trypsinogen gene mutation revealed an arginine to histidine amino acid substitution at the residue 122. Patients with hereditary pancreatitis present with symptoms at an early age and have significant risk for the development of chronic pancreatitis and pancreatic cancer. The risk of pancreatic cancer is estimated to be 53-fold higher after the age of 50 years than the general population. The risk of pancreatic cancer is not related to the type of mutation. Since hereditary pancreatitis is a strong risk factor for pancreatic cancer, it is important to establish a diagnostic criteria for diagnosis and surveillance. However, there are potential benefits, risks and limitations in genetic testing for hereditary pancreatitis. It is difficult to provide the proper treatment, but recent developments in therapeutic approaches may be helpful in caring hereditary pancreatitis. This article includes the current status, pathogenesis, clinical features, and management of hereditary pancreatitis including the aspects of pancreatic cancer.

We report the case of a patient who experienced extreme recurrent gestational hyperlipidemia. She was diagnosed with partial lipoprotein lipase (LPL) deficiency but without an associated LPL gene mutation in the presence of the apolipoprotein E3/2 genotype. This is the first reported case of extreme gestational hyperlipidemia with a partial LPL deficiency in the absence of an LPL gene mutation and the apolipoprotein E 3/2 genotype. She was managed with strict dietary control and medicated with omega-3 acid ethyl esters. A patient with extreme hyperlipidemia that is limited to the gestational period should be considered partially LPL-deficient. Extreme instances of hyperlipidemia increase the risk of acute pancreatitis, and the effect of parturition on declining plasma lipid levels can be immediate and dramatic. Therefore, decisions regarding the timing and route of delivery with extreme gestational hyperlipidemia are critical and should be made carefully.
