There is an increasing prevalence of type 2 diabetes mellitus (DM) among adolescents due to obesity. Diabetes can cause hypertriglyceridemia, defined as triglyceride (TG) levels above 150 mg/dl, leading to severe complications, including cardiovascular events, fatty liver disease, and acute pancreatitis. We present a case of acute pancreatitis manifested by both hypertriglyceridemia and new-onset DM. The risk of hypertriglyceridemia-induced pancreatitis (HTGP) significantly increases at triglyceride levels above 500 mg/dl. Both primary causes, including genetic disorders such as familial chylomicronemia, and secondary disorders of lipid metabolism, including diabetes, hypothyroidism, and pregnancy, could cause HTGP. The toxic levels of triglycerides that break into free fatty acids by pancreatic lipases are critical in pancreatitis pathogenesis. The lipotoxicity, in turn, causes systemic inflammation with further complications related to it. The clinical features of HTGP are similar to other pancreatitis causes, including abdominal pain, nausea, and vomiting. Usually, patients with HTGP tend to have worse outcomes compared to other causes. Due to too high levels of triglycerides, the serum becomes milky and causes an alteration in serum electrolytes levels, including pseudo-hyponatremia. The recommended treatment for HTGP is plasma apheresis as well as IV insulin infusion, and heparin, specifically for less worrisome patients. IV insulin potentially avoids the interventional complexities of apheresis. The usual treatment goal is to reduce the triglycerides to a safe level, and then further management is tailored to lifestyle modification and oral lipid reducing agents. Our case report explains how well insulin works in stable patients with severe pancreatitis and thus prevents associated morbidity and mortality.
由于肥胖,青少年2型糖尿病(DM)的患病率正在上升。糖尿病可导致高甘油三酯血症,定义为甘油三酯(TG)水平高于150mg/dl,进而引发严重并发症,包括心血管事件、脂肪肝疾病和急性胰腺炎。我们报告一例以高甘油三酯血症和新发糖尿病为表现的急性胰腺炎病例。甘油三酯水平高于500mg/dl时,高甘油三酯血症性胰腺炎(HTGP)的风险会显著增加。原发性病因,包括家族性乳糜微粒血症等遗传疾病,以及继发性脂质代谢紊乱,包括糖尿病、甲状腺功能减退和妊娠,均可导致HTGP。甘油三酯被胰腺脂肪酶分解为游离脂肪酸的毒性水平在胰腺炎发病机制中至关重要。反过来,脂毒性会引发全身炎症并伴有与之相关的进一步并发症。HTGP的临床特征与其他胰腺炎病因相似,包括腹痛、恶心和呕吐。通常,与其他病因相比,HTGP患者的预后往往更差。由于甘油三酯水平过高,血清会变得浑浊,并导致血清电解质水平改变,包括假性低钠血症。HTGP的推荐治疗方法是血浆置换以及静脉输注胰岛素和肝素,特别是对于病情较轻的患者。静脉输注胰岛素可能避免了血浆置换的介入复杂性。通常的治疗目标是将甘油三酯水平降至安全范围,然后根据生活方式调整和口服降脂药物进行进一步管理。我们的病例报告解释了胰岛素在重症胰腺炎稳定患者中的良好效果,从而预防了相关的发病率和死亡率。
