Ramadan Flash Glucose Monitoring Study
An observational study of Diabetes Mellitus, run by Imperial College London Diabetes Centre at 2 sites in United Arab Emirates.
Trial summary
Many Muslim patients with diabetes observe dawn to sunset fasting during the month of Ramadan. Hyperglycaemia and hypoglycaemia are possible problems amongst these patients. The aim of this study is to investigate glucose profiles in diabetes and non-diabetes patients that decided to fast or not to fast during Ramadan. Read more about this study

About this study
Official title: Glucose Profiles in Ramadan-fasting Diabetes Patients: Ramadan Flash Glucose Monitoring (RFGM) Study
Many Muslim patients with diabetes observe dawn to sunset fasting during the month of Ramadan. Hyperglycaemia and hypoglycaemia are possible problems amongst these patients. The aim of this study is to investigate glucose profiles in diabetes and non-diabetes patients that decided to fast or not to fast during Ramadan.
Read the detailed description
A good knowledge of the profiles of blood glucose with different treatments can help in making Ramadan fasting free of unwanted effects for such patients. Previous studies, including the EPIDIAR have shown an increased risk of hypo- and hyperglycaemia in patients with diabetes who fast during the Holy month of Ramadan.Although self-monitoring of blood glucose (SMBG) is useful in fasting diabetes patients when used within a structured testing regimen, it requires a lot of effort and compliance from the patient and doesn't provide continuous blood glucose data. The amount of data provided using SMBG depends on the frequency of finger pricks measurements. Flash Glucose Monitoring (FGM) sensors provide a record of the individual's glucose levels, trends and patterns for up to 14 days. This sensor doesn't require calibration using finger pricks. FGM data show how day-to-day decisions and behaviours impact the control of blood sugar levels. Availability of FGM makes it possible to explore glucose profiles in a continuous fashion during Ramadan period and make comparisons with non-fasting times outside Ramadan. The aim of this study is to investigate glucose profiles in diabetes and non-diabetes patients that decided to fast or not to fast during Ramadan. The study will compare several parameters extracted from the FGM trace such us the incident of hypoglycaemia and hyperglycaemia, standard deviation, coefficient of variance and time in/above/below range. For this purpose the FreeStyle Libre sensor will be used. Patients will be asked to use the FreeStyle Libre sensor for a period of 3 months: 1 month before Ramadan, during Ramadan and one month after Ramadan.

Questions about this trial
What is this clinical trial studying?
An observational study of Diabetes Mellitus, run by Imperial College London Diabetes Centre at 2 sites in United Arab Emirates.
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 24 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United Arab Emirates. 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?
Change in mean glucose level; (mmol/L) (time frame: Pre-Ramadan (30 days), Ramadan (29 days), Post-Ramadan (30 days)). The study lists 4 primary outcomes in all. 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 24 Apr 2020.
