Abstract
BACKGROUND AND AIM APO CII, one of several cofactors which regulate lipoprotein lipase enzyme activity, plays an essential role in lipid metabolism. Deficiency of APO CII is an ultra-rare autosomal recessive cause of familial chylomicronemia syndrome. We present the long-term clinical outcomes of 12 children with APO CII deficiency. METHODS AND RESULTS The data of children with genetically confirmed APO CII deficiency were evaluated retrospectively. Twelve children (8 females) with a mean follow-up of 10.1 years (±3.9) were included. At diagnosis, the median age was 60 days (13 days-10 years). Initial clinical findings included lipemic serum (41.6%), abdominal pain (41.6%), and vomiting (16.6%). At presentation, the median triglyceride (TG) value was 4341 mg/dL (range 1277-14,110). All patients were treated with a restricted fat diet, medium-chain triglyceride (MCT), and omega-3-fatty acids. In addition, seven patients (58.3%) received fibrate. Fibrate was discontinued in two patients due to rhabdomyolysis and in one patient because of cholelithiasis. Seven (58.3%) patients experienced pancreatitis during the follow-up period. One female experienced recurrent pancreatitis and was treated with fresh frozen plasma (FFP). CONCLUSIONS Apo CII deficiency is an ultra-rare autosomal recessive condition of hypertriglyceridemia associated with significant morbidity and mortality. Low-fat diet and MCT supplementation are the mainstays of therapy, while the benefit of TG-lowering agents are less well-defined.

Abstract
Transitional medicine refers to the seamless continuity of medical care for patients with childhood-onset diseases as they grow into adulthood. The transition of care must be seamless in medical treatment as the patients grow and in other medical aids such as subsidies for medical expenses in the health care system. Inappropriate transitional care, either medical or social, directly causes poorer prognosis for many early-onset diseases, including primary dyslipidemia caused by genetic abnormalities. Many primary dyslipidemias are designated as intractable diseases in the Japanese health care system for specific medical aids, as having no curative treatment and requiring enormous treatment costs for lipid management and prevention of complications. However, there are problems in transitional medicine for primary dyslipidemia in Japan. As for the medical treatment system, the diagnosis rate remains low due to the shortage of specialists, their insufficient link with generalists and other field specialists, and poor linkage between pediatricians and physicians for adults. In the medical care system, there is a mismatch of diagnostic criteria of primary dyslipidemias between children and adults for medical care expense subsidization, as between The Program for the Specific Pediatric Chronic Diseases and the Program for Designated Adult Intractable Diseases. This could lead some patients subsidized in their childhood to no longer be under the coverage of the aids after transition. This review intends to describe these issues in transitional medicine of primary dyslipidemia in Japan as a part of the efforts to resolve the problems by the Committee on Primary Dyslipidemia under the Research Program on Rare and Intractable Disease of the Ministry of Health, Labour and Welfare of Japan.

Abstract
This report presents a case of a male infant, aged 32 days, who was admitted to the hospital due to 2 days of bloody stools and 1 day of fever. Upon admission, venous blood samples were collected, which appeared pink. Blood biochemistry tests revealed elevated levels of triglycerides and total cholesterol. The familial whole genome sequencing revealed a compound heterozygous variation in the LPL gene, with one variation inherited from the father and the other from the mother. The patient was diagnosed with lipoprotein lipase deficiency-related hyperlipoproteinemia. Acute symptoms including bloody stools, fever, and bloody ascites led to the consideration of acute pancreatitis, and the treatment involved fasting, plasma exchange, and whole blood exchange. Following the definitive diagnosis based on the genetic results, the patient was given a low-fat diet and received treatment with fat-soluble vitamins and trace elements, as well as adjustments to the feeding plan. After a 4-week hospitalization, the patient's condition improved and he was discharged. Follow-up showed a decrease in triglycerides and total cholesterol levels. At the age of 1 year, the patient's growth and psychomotor development were normal. This article emphasizes the multidisciplinary diagnosis and treatment of familial hyperlipoproteinemia presenting with symptoms suggestive of acute pancreatitis, including bloody ascites, in the neonatal period.

Abstract
A one-year-and-nine-month-old Japanese boy was admitted with hypertriglyceridemia (fasting triglycerides 2548 mg/dL). After close examination, he was diagnosed with lipoprotein lipase (LPL) deficiency (compound heterozygous) and was immediately started on a fat-restricted dietary therapy. He responded well to the regimen (1200 kcal/day, 20 g fat/day) and his triglycerides decreased to 628 mg/dL within 7 days of starting the dietary therapy. It was decided to manage his illness without using any drugs because he was still an infant and responded well to a fat-restricted diet. During his hospital stay, dietitians provided him with nutritional counseling using a food exchange list, which was designed to easily calculate the fat content by including foods that are commonly served. His family quickly learned the skills to prepare a fat-restricted diet. Moreover, since dietary restrictions may have impaired the child's growth and development, the dietitians continued to intervene regularly after the child was discharged from the hospital. The dietitians confirmed that the patient was receiving nutritional intake appropriate for his growth and discussed the dietary concerns in his daily life and how to participate in school events that involved eating and drinking. Nutritional counseling was provided every 3-4 months from disease onset to age 23 years, except for a 14-month break at age 20 years. The patient grew up without developing acute pancreatitis, a serious complication of LPL deficiency. The long-term intervention of dieticians is necessary to achieve a balance between living on a strict diet for disease management and ensuring appropriate nutritional intakes for growth/development.

Abstract
Hypertriglyceridemia is a lipid disorder with a varying prevalence; it is very common if we consider triglyceride plasma values slightly above the threshold, whereas it is extremely rare if only severely elevated triglyceride levels are considered. In most cases, severe forms of hypertriglyceridemia are caused by genetic mutations in the genes that regulate triglyceride metabolism, thus leading to extreme triglyceride plasma values and acute pancreatitis risk. Secondary forms of hypertriglyceridemia are usually less severe and are mainly associated with weight excess, but they can also be linked to liver, kidney, endocrinologic, or autoimmune diseases or to some class of drugs. Nutritional intervention is the milestone treatment for patients with hypertriglyceridemia and it has to be modulated on the underlying cause and on triglyceride plasma levels. In pediatric patients, nutritional intervention must be tailored according to specific age-related energy, growth and neurodevelopment requests. Nutritional intervention is extremely strict in case of severe hypertriglyceridemia, whereas it is similar to good healthy nutritional habits counselling for mild forms, mainly related to wrong habits and lifestyles, and to secondary causes. The aim of this narrative review is to define different nutritional intervention for various forms of hypertriglyceridemia in children and adolescents.

CHILDREN (BASEL, SWITZERLAND) 2021; 8:children8111078. [PMID: 34828789 PMCID: PMC8619212 DOI: 10.3390/children8111078] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 11/17/2021] [Accepted: 11/17/2021] [Indexed: 06/13/2023]
Abstract
(1) Background: Familial chylomicronemia syndrome (FCS) is a very rare autosomal recessive disorder characterized by severely elevated triglycerides and clinical symptoms in early childhood mainly presenting with abdominal pain, acute pancreatitis and hepatosplenomegaly. Primary treatment is a lifelong very strict low-fat diet, which might be challenging in pediatric patients. So far, data about children with FCS are rare. The aim of this study was to show the familial chylomicronemia syndrome traffic light table for pediatric patients and to assess the dietary fat intake and impact on triglycerides in children with FCS. (2) Methods: We performed a retrospective analysis in four children (50% male) affected by FCS from the Department of Pediatrics and Adolescent Medicine, Medical University of Vienna between January 2002 and September 2020. (3) Results: The four patients presented with classical FCS symptoms and showed baseline triglycerides (TG) exceeding 30,000 mg/dL in two patients, 10,000 mg/dL and 2400 mg/dL in one patient each. After diagnosis, fat percentage of total daily caloric intake was decreased and resulted immediately in triglyceride reduction. In all patients, FCS was genetically confirmed by mutations in genes encoding lipoprotein lipase. Acute pancreatitis and hepatosplenomegaly disappeared under the fat-restricted diet. A FCS traffic light table was developed as a dietary tool for affected families. (4) Conclusions: A restriction of dietary fat between 10% to 26% of the total daily caloric intake was feasible and effective in the long-term treatment of genetically confirmed FCS in children and could reduce the risk for acute pancreatitis. The dietary tool, the pediatric FCS traffic light table and the age-appropriate portion sizes for patients between 1 to 18 years, supports children and their parents to achieve and adhere to the lifelong strict low-fat diet.

Abstract
Primary chylomicronemia (PCM) is a rare and intractable disease characterized by marked accumulation of chylomicrons in plasma. The levels of plasma triglycerides (TGs) typically range from 1,000 - 15,000 mg/dL or higher.
PCM is caused by defects in the lipoprotein lipase (LPL) pathway due to genetic mutations, autoantibodies, or unidentified causes. The monogenic type is typically inherited as an autosomal recessive trait with loss-of-function mutations in LPL pathway genes (
LPL
,
LMF1
,
GPIHBP1
,
APOC2
, and
APOA5
). Secondary/environmental factors (diabetes, alcohol intake, pregnancy, etc.) often exacerbate hypertriglyceridemia (HTG).
The signs, symptoms, and complications of chylomicronemia include eruptive xanthomas, lipemia retinalis, hepatosplenomegaly, and acute pancreatitis with onset as early as in infancy. Acute pancreatitis can be fatal and recurrent episodes of abdominal pain may lead to dietary fat intolerance and failure to thrive. The main goal of treatment is to prevent acute pancreatitis by reducing plasma TG levels to at least less than 500-1,000 mg/dL. However, current TG-lowering medications are generally ineffective for PCM. The only other treatment options are modulation of secondary/environmental factors. Most patients need strict dietary fat restriction, which is often difficult to maintain and likely affects their quality of life. Timely diagnosis is critical for the best prognosis with currently available management, but PCM is often misdiagnosed and undertreated. The aim of this review is firstly to summarize the pathogenesis, signs, symptoms, diagnosis, and management of PCM, and secondly to propose simple diagnostic criteria that can be readily translated into general clinical practice to improve the diagnostic rate of PCM. In fact, these criteria are currently used to define eligibility to receive social support from the Japanese government for PCM as a rare and intractable disease. Nevertheless, further research to unravel the molecular pathogenesis and develop effective therapeutic modalities is warranted. Nationwide registry research on PCM is currently ongoing in Japan with the aim of better understanding the disease burden as well as the unmet needs of this life-threatening disease with poor therapeutic options.

Abstract
OBJECTIVES To analyse the clinical and molecular spectrum of Lipoprotein Lipase (LPL) deficiency and to highlight the effect of a cost-effective indigenous diet for management of this disorder. METHODS This is a single-centre retrospective study. Fifteen patients from 14 kindreds with severe hypertriglyceridemia (more than 1000 mg/dl) were evaluated for a period of 12.5 y at Amrita Institute of Medical Sciences, Kerala, India. RESULTS Thirteen of 15 patients were referred after incidental detection of lipemic plasma, 1/15 had chylothorax in the neonatal period and 1/15 had pancreatitis. The mean age of presentation was 7 mo (ranging from 2 d to 4 y), and 20% of the patients had a positive history of consanguinity. Hepatomegaly (15/15), splenomegaly (9/15) and lipemia retinalis (14/15) were common findings. Lipemia retinalis was a useful non-invasive diagnostic tool. All the patients were subjected to diet modification and followed up at regular intervals. Fourteen of 15 complied with the diet, resulting in a dramatic improvement in the fasting lipid profile; only 1/15 developed pancreatitis. Genetic screening analysis was offered to 14/15 patients (1/15 was lost to follow-up); six different variants were identified, of which two were novel variants. CONCLUSIONS Lipemic serum, chylothorax and recurrent pancreatitis in children should raise the suspicion of Lipoprotein Lipase deficiency. Early diagnosis and prompt initiation of a stringent fat-restricted diet are the keys to success for the management of LPL deficiency and prevention of pancreatitis.

Abstract
PURPOSE OF REVIEW Familial chylomicronemia syndrome (FCS) is a rare recessive genetic disorder often underdiagnosed with potentially severe clinical consequences. In this review, we describe the clinical and biological characteristics of the disease together with its main complication, i.e., acute pancreatitis. We focused the paper on new diagnostic tools, progress in understanding the role of two key proteins (apolipoprotein CIII (apo CIII) and angiopoietin-like3 (ANGPTL-3)), and new therapeutic options. RECENT FINDINGS Recently, a new diagnostic tool has been proposed by European experts to help identify these patients. This tool with two recently identified parameters (low LDL and low body mass index) can help identify patients who should be genetically tested or who may have the disease when genetic testing is not available. FCS is caused by homozygous or compound heterozygous mutations of lipoprotein lipase, apolipoprotein C-II, apolipoprotein A-V, glycosylphosphatidylinositol anchored high-density lipoprotein-binding protein 1, and lipase maturation factor. Two proteins have been identified as important player in the metabolism of triglyceride-rich lipoprotein and its regulation. These two proteins are therapeutic target. Antisense oligonucleotide targeting apo CIII has been shown to significantly decrease triglyceride levels even in FCS and is the first available treatment for these patients. Further development might identify new compounds with reduced risk to develop severe thrombocytopenia. ANGPTL-3 inhibitors have not yet been tested in FCS patients but exert significant hypotriglyceridemic effect in the more frequent and less severe polygenic forms. Beyond these two new targets, microsomal triglyceride transfer protein (MTTP) inhibitors could also be part of the armamentarium, if on-going trials confirm their efficacy. New clinical tools and simple criteria can help select patients with possible FCS and identify patients who should have a genetic testing. Identifying patients with FCS is a major issue since these patients have a high risk to suffer severe episodes of acute pancreatitis and may now benefit from new therapeutic options including antisense oligonucleotide targeting apo CIII.

Abstract
BACKGROUND Volanesorsen, an investigational inhibitor of apoC-III synthesis, significantly reduced triglyceride levels in clinical trials in patients with familial chylomicronemia syndrome (FCS), a rare genetic disorder characterized by marked chylomicronemia leading to a spectrum of symptoms, including recurrent abdominal pain and episodes of potentially fatal acute pancreatitis (AP). OBJECTIVE To determine the effect of volanesorsen on burden of disease on patients with FCS Methods: ReFOCUS was a retrospective global web-based survey open to patients with FCS who received volanesorsen for ≥3 months in an open-label extension study. The survey included questions about patients' experiences before and after volanesorsen treatment. RESULTS Twenty-two respondents had received volanesorsen for a median of 222 days. Volanesorsen significantly reduced the number of symptoms per patient across physical, emotional, and cognitive domains. Significant reductions from baseline were reported for steatorrhea, pancreatic pain, and constant worry about an attack of pain/AP. Respondents reported that volanesorsen improved overall management of symptoms and reduced interference of FCS with work/school responsibilities. Reductions in the negative impact of FCS on personal, social, and professional life were also reported. CONCLUSIONS Treatment with volanesorsen has the potential to reduce disease burden in patients with FCS through modulation of multiple symptom domains.

Abstract
BACKGROUND Familial chylomicronemia syndrome (FCS) is a rare genetic disorder characterized by a deficiency of lipoprotein lipase leading to extreme hypertriglyceridemia. Patients' burden of illness and quality of life have been poorly addressed in the literature. OBJECTIVE To understand the ways in which FCS impacts patients' lives. METHODS Investigation of Findings and Observations Captured in Burden of Illness Survey (IN-FOCUS) was a global web-based survey open to patients with FCS. Survey questions captured information on diagnostic experience, symptoms, comorbidities, disease management, and impact on multiple life dimensions. RESULTS Of 166 patients in 10 countries, 62% were from the United States and 70% were male. Median age at the time of the survey was 33 years, and median age at diagnosis was 9 years. Patients saw a mean of 5 physicians from different specialties before their FCS diagnosis and experienced multiple physical, emotional, and cognitive symptoms on a daily to monthly basis; 40% were admitted to the hospital in the past year. A lifetime mean of 13 episodes occurred in the 40% of patients with FCS-related acute pancreatitis. Most patients (>90%) found managing fat intake to be difficult, and 53% experienced symptoms despite adherence to their diets. FCS impacted employment status (94%), emotional/mental well-being (58%-66%), and social relationships (68%-82%). CONCLUSIONS Patients with FCS experience significant clinical and psychosocial burdens that reduce their quality of life and limit employment and social interactions. Increased awareness among healthcare professionals of the multifaceted nature of the FCS disease burden may help expedite diagnosis and timely institution of treatment and broaden management considerations.
