Effects of liraglutide addition to multiple diabetes regimens on weight and risk of hypoglycemia for a cohort with type 2 diabetes followed in primary care clinics in Saudi Arabia

Clinical studies on anti-obesity medications in Arab countries

OBJECTIVES

To identify and summarize studies carried out in Arab countries on anti-obesity medications (AOMs), with a focus on the types of medications investigated, study designs, and the efficacy/effectiveness and safety metrics reported.

METHODS

We carried out a comprehensive scoping review of primary studies examining the use of AOMs in adult Arab populations. Five databases (Medline, Embase, Cochrane Library, Index Medicus for the Eastern Mediterranean Region, and e-Marefa) were searched for English-language publications up to October 2024. Data extraction was carried out on study characteristics, participant demographics, interventions, and outcomes related to weight reduction, metabolic parameters, and side effects. The risk of bias (RoB) was assessed using the Newcastle-Ottawa scale for non-randomized studies and a modified RoB tool for randomized controlled trials.

RESULTS

A total of 59 clinical studies published between 2014-2024 were included. The majority (89.8%) were observational in design. Most studies were carried out in Saudi Arabia (40.7%) and the United Arab Emirates (20.3%). Glucagon-like peptide-1 receptor agonists were investigated in 72.9% of the studies, with liraglutide being the most frequently studied agent (54.2%). The most commonly reported efficacy outcomes included changes in total body weight (45.8%), body mass index (39.0%), and the proportion of weight loss (28.8%). Gastrointestinal side effects were reported in 32.2% of patients across studies.

CONCLUSION

Despite the growing body of research on AOMs in Arab countries, most studies remain observational and focus primarily on earlier-generation agents. There is a need for randomized controlled trials to evaluate the efficacy and safety of newer AOMs, such as semaglutide and tirzepatide, within Arab populations to inform culturally and genetically tailored obesity management strategies.

Liraglutide Effect on Weight and A1C in Patients with Type 2 Diabetes Mellitus: Real-World Data from a Single Tertiary Care Center in Saudi Arabia

Objective

This retrospective study aimed to determine the effect of liraglutide on weight and HbA1c levels in patients with type 2 diabetes mellitus (T2DM) in Saudi Arabia. The present investigation was carried out at a medical facility located in the Kingdom of Saudi Arabia.

Materials and Methods

A retrospective analysis was conducted on the clinical records of 290 patients who were diagnosed with T2DM and were above 18 years of age. These patients were administered liraglutide for a minimum of 6 months. The dataset comprised various parameters such as the duration of diabetes, duration of liraglutide therapy, weight, and multiple biochemical markers such as HbA1c and low-density lipoprotein cholesterol levels. These parameters were measured both before and after the administration of liraglutide therapy.

Results

The primary metrics evaluated in this study were alterations in body weight and levels of glycated hemoglobin (HbA1c). Over the 24-month observational period, significant reductions in body mass index (38.6 kg/m2 to 37 kg/m2), body weight (99.3 kg to 96 kg), and HbA1c levels (8.9% to 7.8%) (all P < 0.01) were seen.

Conclusion

Liraglutide reduced HbA1c levels and weight and affected multiple metabolic markers in patients with T2DM in a real-world setting in Saudi Arabia.

Prevalence, risk factors, and interventions for obesity in Saudi Arabia: A systematic review

Saudi Arabia (SA) has a reported obesity prevalence greater than the global average. Here, we systematically review firstly the prevalence and associated factors (59 studies) and secondly the pharmacological, lifestyle, and surgical interventions for obesity (body mass index, >30 kg/m² ) in SA (29 studies) between December 2020 and March 2021 in PubMed, Medline, Embase, PsycINFO, and Cochrane. Peer-reviewed articles in Arabic and English on human adults (aged >18 years) were searched. Among the eight largest studies with sample sizes over 10,000 people, the maximum-reported obesity prevalence was 35.6%, with notable variations in gender and geographic region. Diet, specifically the move towards Western diet and heavy consumption of sugary beverages, and high levels of inactivity are major contributing factors to obesity. The reported obesity-risk polymorphisms are not specific. Bariatric surgery is underrepresented, and in general, there is a lack of nationally coordinated studies on weight loss interventions. In particular, the systematic review did not find a body of research on psychological interventions. There is no trial data for the use of GLP-1 analogs in SA, despite their widespread use. These findings can help policymakers, and practitioners prioritize future research efforts to reduce obesity prevalence in SA.

The Efficacy and Safety of Liraglutide 3.0 mg for Weight Management in Obese Non-Diabetic Saudi Outpatients

BACKGROUND

Unmanaged cases of obesity might lead to serious conditions and complications, which impair patients' lives. The aim of this study was to assess the effectiveness and safety of daily 3 mg subcutaneous (s/c) Liraglutide amongst obese non-diabetic patients in Eastern Province, Saudi Arabia.

METHODS

A retrospective cohort study of obese non-diabetic Saudi patients with obesity managed with s/c Liraglutide 3.0 mg who visited the outpatient clinic in Al Mashfa Hospital, Al Khobar, KSA during 2019-2021. We collected patient data from the electronic reporting system for different parameters. Body weight, hemoglobin A1c %, systolic and diastolic blood pressure mmHg were obtained at baseline and after the intervention.

RESULTS

Records of 258 patients who were using a daily dose of Liraglutide 3.0 mg s/c for at least four months have been reviewed. The body weight loss of patients who used Liraglutide for four months was 8.1±0.8 kg. Moreover, around 204 patients continued for up to six months. Meanwhile, the mean body weight loss was 13 kg. There was a significant reduction of hemoglobin A1c (HbA1c) % by 0.43%. The majority of patients (94.5%) reported satisfaction with the treatment, while adverse events were mainly nausea, vomiting and constipation.

CONCLUSION

Daily s/c Liraglutide of 3.0 mg is effective in producing significant body weight reduction in obese non-diabetic Saudi patients with tolerable minimal side effects and may provide health benefits in terms of reduced risk of obesity and its related outcomes.

Liraglutide effects on glycemic control and weight in patients with type 2 diabetes Mellitus: A real-world, observational study and brief narrative review

BACKGROUND

Glycemic control and weight gain are two essential considerations in the pharmacological management of type 2 diabetes mellitus. Pharmacological agents are effective in lowering blood glucose levels but may result in significant weight gain. Liraglutideeffectively maintains glycemic control while reducingweight.

METHODS

This is a real-world study and brief narrative review of the effects of liraglutide on glycemic control and weight in adult patients with type 2 diabetes mellitus. The study uses data extracted from the electronic health record of the Ministry of National Guard-Health Affairs.

RESULTS

In this study of 348 subjects, there was a statistically significant reduction in hemoglobin A1c of 0.9% (P < .0001) and weight of 2.3 kg (P < .0001). The majority (77.3%) were on concomitant insulin.Subjects with a baseline hemoglobin A1c greater than 9% had a significantly greater reduction than those below 9% (-0.7%;P < .0001). Those with a weight more than 100 kg had a significantly greater reduction than those below 100 kg (-0.9 kg;P = .0096).

CONCLUSION

In this real-world, observational study, liraglutide was shown to be effective in improving glycemic control and reducing weight in adult patients with type 2 diabetes mellitus.
