Síndrome de quilomicronemia familiar: experiencia pediátrica en Argentina / Familial chylomicronemia syndrome: pediatric experience in Argentina

El síndrome de quilomicronemia familiar (SQF) es unaenfermedad autosómica recesiva rara, con una prevalencia1:200 000 - 1:1 000 000, y se caracteriza por quilomicronemiaen ayunas y niveles muy elevados de triglicéridos (> 880 mg/dl). LPL es el gen más frecuentemente afectado, luego APOC2,GPIHBP1, APOA5 y LMF1; todos ellos comprometen la función de la lipoproteinlipasa endotelial. El SQF suele presentarseen la infancia con dolor abdominal recurrente, xantomaseruptivos, retraso del crecimiento, pancreatitis y, en ocasiones,asintomático. El tratamiento convencional es la restriccióndietética de grasas. Se muestra el resultado clínico de 20 pacientes pediátricoscon SQF reclutados de 4 hospitales en Argentina.

Familial chylomicronemia syndrome (FCS) is a rare autosomalrecessive disease, prevalence 1:200,000 - 1:1,000,000, andis characterized by fasting chylomicrons and very hightriglycerides > 880 mg/dl. LPL is the most frequentlyaffected gene, then APOC2, GPIHBP1, APOA5, LMF1, all ofthem compromising the function of lipoproteinlipase. FCScommonly presents in childhood with recurrent abdominalpain, eruptive xanthomas, failure to thrive, pancreatitis, andsometimes asymptomatic. The conventional treatment isdietetic fat restriction. The clinical outcome of 20 pediatric patients with FCS recruited from 4 hospitals in Argentina is reported.

Familial chylomicronemia syndrome-induced acute necrotizing pancreatitis during pregnancy

Abstract Acute pancreatitis is a rare condition in pregnancy, associated with a high mortality rate. Hypertriglyceridemia represents its second most common cause.We present the case of a 38-year-old woman in the 24th week of gestation with a history of hypertriglyceridemia and recurrent episodes of pancreatitis. She was admitted to our hospital with acute pancreatitis due to severe hypertriglyceridemia. She was stabilized and treated with fibrates. Despite her favorable clinical course, she developed a second episode of acute pancreatitis complicated by multi-organ dysfunction and pancreatic necrosis, requiring a necrosectomy. The pregnancy was ended by cesarean section, after which three plasmapheresis sessions were performed. She is currently asymptomatic with stable triglyceride levels. Acute pancreatitis due to hypertriglyceridemia represents a diagnostic and therapeutic challenge in pregnant women, associated with serious maternal and fetal complications. When primary hypertriglyceridemia is suspected, such as familial chylomicronemia syndrome, the most important objective is preventing the onset of pancreatitis.

Familial chylomicronemia in a nine months old infant

Familial Chylomicronemia syndrome is a rare disorder of lipoprotein metabolism due to familial lipoprotein lipase or apolipoprotein C-II deficiency or the presence of inhibitors to lipoprotein lipase. It manifests as eruptive xanthomas, acute pancreatitis, and lipaemic plasma due to marked elevation of triglyceride and chylomicrons levels. We report a rare case of familial Chylomicronemia in a 9-month-old infant, who was diagnosed after his plasma was incidentally found to be milky. Lipid profile showed familial Chylomicronemia [Type 1 Hyperlipidemia]. The infant was started on a low fat diet and advised a regular follow-up

Familial chylomicronemia syndrome.

Familial chylomicronemia syndrome is a group of rare genetic disorders characterized by deficient activity of an enzyme lipoprotein lipase or apo-protein C-II deficiency. Incidence is 1 out of 1,000,000. Alternative names to this syndrome are Type I hyper lipoproteinemia and familial lipoprotein lipase deficiency.

Hiperlipoproteinemia tipo I / Type I hyperlipoproteinemia

Se presenta el caso clínico de una paciente portadora de una hiperlipoproteinemia tipo I controlada durante 5 años. Se describe las características clínicas y de laboratorio de esta enfermedad así como la respuesta al tratamiento dietético que es fundamental en la evolución de esta alteración metabólica tan poco frecuente
