  • The pain may be located in the upper, central region (epigastric area) of the abdomen and can radiate to cause back pain. In some cases, the pain may be widespread (diffuse) and can potentially resemble acute abdomen (peritonitis).[rarediseases.org]
Knee Pain
  • I regularly experienced severe diarrhea, chronic knee pain, extreme fatigue, abdominal pain and distention, and itchy, scaly rashes on my skin. Even from the time I was born I was experiencing symptoms.[globalgenes.org]
Scaly Rash
  • I regularly experienced severe diarrhea, chronic knee pain, extreme fatigue, abdominal pain and distention, and itchy, scaly rashes on my skin. Even from the time I was born I was experiencing symptoms.[globalgenes.org]
Social Isolation
  • isolation due to diet Diagnosis FCS is diagnosed based on fasting triglyceride levels above or 750 mg/dL (8.5 mmol/L), which do not respond to standard lipid lowering therapy ( Brahm and Hegele 2015 ), a history of recurrent abdominal pain and/or pancreatitis[pancreasfoundation.org]
Unable to Walk
  • I had experienced abdominal pain before, but this was different; the pain was so excruciating I was unable to walk.[globalgenes.org]

Workup

  • A thorough history, physical examination, and laboratory workup failed to identify a clear etiology of the extremely abnormal blood lipid level, prompting genetic investigation to identify the genetic cause of the milky serum.[lipidworld.biomedcentral.com]
  • Clinical Testing and Workup Blood tests can reveal reduced activity of the lipoprotein lipase enzyme in the plasma, following intravenous administration of heparin.[rarediseases.org]
Pancreatic Necrosis
  • necrosis as identified via contrast CT-scan findings 48% developed persistent organ failure 8% died In patients with FCS, episodes of abdominal pain and pancreatitis can be recurrent. 2 In one study, 59% of patients with FCS had a history of recurrent[fcs.raredr.com]
  • Patients with extremely high levels of triglycerides may have a more severe course of pancreatitis, leading to worse outcomes including longer hospital stays, a higher rate of pancreatic necrosis, more frequent persistent organ failure, and higher rates[pancreasfoundation.org]
  • Pancreatitis in LPL deficiency may rarely be associated with total pancreatic necrosis and death.[ncbi.nlm.nih.gov]

Treatment

  • Patients then underwent three consecutive 21 day treatment periods (pradigastat at 20, 40 & 10 mg, respectively). Treatment periods were separated by washout periods of 4 weeks. Fasting TG levels were assessed weekly through the treatment periods.[ncbi.nlm.nih.gov]
  • CONCLUSIONS: Treatment with volanesorsen has the potential to reduce disease burden in patients with FCS through modulation of multiple symptom domains.[ncbi.nlm.nih.gov]
  • This treatment effect was sustained over the 52-week treatment period.[healio.com]
  • Areas covered: In this review, authors discuss chronic treatment of FCS by ultra-low fat diets allied with the use of fibrates, omega-3 fatty acids, niacin, statins, and insulin-sensitizing therapies depending on the extent of residual lipoprotein lipase[ncbi.nlm.nih.gov]

Prognosis

  • Therefore, the prognosis of individuals with chylomicronemia syndrome is not so bleak after all. They can lead a relatively normal life, and to be honest, with a healthier diet than many people without the disease.[chylomicronemiasyndrome.wordpress.com]

  • Timely dietary modification could improve the prognosis and maintain a normal lifestyle for affected children, by reducing the risk of some complications.[lipidworld.biomedcentral.com]

Etiology

  • The chylomicronemia syndrome is well recognized as a rare etiologic factor of acute pancreatitis; however, whether hypertriglyceridemia can cause chronic pancreatitis (CP) remains unclear.[ncbi.nlm.nih.gov]
  • Other etiologic factors were excluded, including mutations in the PRSS1, SPINK1, and CFTR gene. Although both brothers had recurrent acute pancreatitis and the same LPL genotype, CP became evident in only one patient.[journals.lww.com]
  • In our cases, genetic investigation could help to identify the etiology of infants with milky serum for the heterogeneity of FCS in the young group.[lipidworld.biomedcentral.com]
  • […] of Hypertriglyceridemia Hypertriglyceridemia has been classified as primary when the cause is genetic, and as secondary when the etiology relates to other diseases that affect triglyceride metabolism, medications, or dietary factors.[cmecorner.com]
  • Moreover in this case report, etiology, diagnostic challenges and therapeutic options for such increased levels of triglycerides are discussed. 1. Introduction Drinking milk has been considered to fit in a healthy diet.[file.scirp.org]

Epidemiology

  • The disorder affects about 1 out of 1,000,000 people; however, epidemiological data are limited and there are regional differences due to cofounder effect (e.g. in Canada) or intermarriage.[en.wikipedia.org]
