Study population: cross-sectional study involving a sample of FCS and MCS patients in 1:1 ratio. The study was run in seven academic reference centers in France. Adult patients with documented history of fasting TG > 10 mmol/L (885 mg/dL) were recruited. Patients had to be genetically characterized or MCS patients had a MCS score ≤ 9 [11]. Group sample sizes of 19 FCS and 19 MCS have been calculated to achieve an at least 80% power to detect a 40% difference in the frequency of abdominal pain assuming that 90% of FCS patients would complain about abdominal pain
Who may be able to join
- any adult FCS patient genetically documented any adult MCS patient genetically or phenotypically documented
Who cannot join

Read the detailed description
cross-sectional study involving a sample of FCS and MCS patients in 1:1 ratio. The study was run in seven academic reference centers in France. Adult patients with documented history of fasting TG > 10 mmol/L (885 mg/dL) were recruited. Patients had to be genetically characterized or MCS patients had a MCS score ≤ 9 [11]. Group sample sizes of 19 FCS and 19 MCS have been calculated to achieve an at least 80% power to detect a 40% difference in the frequency of abdominal pain assuming that 90% of FCS patients would complain about abdominal pain.
The study protocol was approved by a nationally appointed ethics committee (Comité de Protection des Personnes - Ile de France 5) under number 18040. The study protocol complied with the ethical guidelines of the Declaration of Helsinki and the French Bioethics Law Jarde. The data management complied with the CNIL requirement. Each patient was informed about the aims and constraints of the study and signed a non-opposition form prior to any study procedure.
Health Burden assessment The French IN-FOCUS study was designed to capture current and retrospective data in FCS or MCS. Patients were called by the participating centers and were proposed to answer a paper questionnaire or to connect to a web-based questionnaire The questionnaire was divided into sections specifically assessing various domains of their experience: demographic data, signs, symptoms and complications of the disease, healthcare circuit, management, relationship with healthcare providers, and burden of the disease on daily life. (Details are available as supplementary material S1). The questionnaire focused on symptoms because the interest of quality of life assessment tools is debated in rare diseases with episodic manifestations. Indeed, most of these tools refer to a limited recall period.
Data analysis The statistical analysis was performed by Soladis (Lyon, France) using the Statistical Analysis System (SAS) software 9.4 (SAS Institute, Cary, NC, USA). Continuous variables were summarized by the number of observed data, mean, standard deviation (SD), median, first and third quartiles. Categorical variables were described as numbers and percentages calculated on the number of observed data. FCS and MCS subjects were compared using Student's t test or U Mann-Whitney's test. Categorical variables were compared by the chi squared test or the Fisher's exact test. Tests were two-sided and the significance threshold was set at 5%. No adjustment of the Type 1 error risk was made for multiplicity. Impact of history of AP was evaluated in a multivariable model (logistic regression for binary variables, ordinal logistic regression for ordinal variables) including the type of disease (FCS or MCS), history of AP and the interaction between these two predictors.

What is being measured
The primary outcome is the main question the study is designed to answer.
abdominal pain
Symptoms were assessed as present/absent within the 12 months prior to the study; if present, the patient was asked to rate their frequency (yearly, every 3 months, monthly, weekly, daily using a 5-point verbal numeric scale) and severity using a 7-point verbal numeric scale with 1=very mild and 7=very important.
Measured: 12 previous months record
Secondary outcomes (2)
dietary burden
Consuming more fats than allowed to avoid attracting attention Longing for rich-fat food Meals lack variety Carefully reading the food labelling Feeling frustrated by his/her diet Controlling fat consumption is a hard task Avoids alcohol consumption to prevent symptoms Fasting voluntarily Preparing a special meal different from the rest of the family
Symptoms were assessed as present/absent within the 12 months prior to the study; if present, the patient was asked to rate their frequency (yearly, every 3 months, monthly, weekly, daily using a 5-point verbal numeric scale) and severity using a 7-point verbal numeric scale with 1=very mild and 7=very important.
Measured: 12 previous months records
psychological burden
Feeling anxious when eating out Feeling anxious if not compliant with his/her diet Trouble concentrating due to insufficient satiety Feeling guilty when drinking small amounts of alcohol Symptoms were assessed as present/absent within the 12 months prior to the study; if present, the patient was asked to rate their frequency (yearly, every 3 months, monthly, weekly, daily using a 5-point verbal numeric scale) and severity using a 7-point verbal numeric scale with 1=very mild and 7=very important.
Measured: 12 previous months record

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
FCS and MCS patients recruited from 7 academic reference centers were invited to answer a paper or a web questionnaire. Questions encompassed demographics, physical, cognitive and mental symptoms, health care circuit, past and current disease management, satisfaction regarding healthcare providers and impact on daily life.

What is this clinical trial studying?
An observational study of Familial Chylomicronemia Syndrome and Multifactorial Chylomicronemia Syndrome, run by New French Society of Atherosclerosis at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
abdominal pain (time frame: 12 previous months record). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jan 2020.
