TOPLINE:
Clients treated with glucagon-like peptide 1 receptor agonists (GLP-1 RAs) appear to have a really low occurrence of nonarteritic anterior ischemic optic neuropathy (NAION) when properly recommended for weight problems or diabetes.
APPROACH:
- A retrospective observational research study just recently recommended that semaglutide treatment might be connected with more than a fourfold boost in the threat for NAION, an uncommon condition possibly causing loss of sight that is more regular in individuals with weight problems and diabetes.
- To examine the danger for NAION in adult clients getting GLP-1 RAs for diabetes or weight problems, scientists performed this meta-analysis, that included 69 randomized regulated trials that lasted a minimum of 12 months, compared GLP-1s to a placebo or an active comparator (control arm), and revealed a total list of severe negative occasions.
- The analysis consisted of 144,226 and 132,922 patient-years in the GLP-1 RA and control arms, respectively, and the trials utilized liraglutide (23 trials), semaglutide (19 trials), exenatide (15 trials), dulaglutide (7 trials), and lixisenatide (one trial).
- The majority of trials (n = 52) registered clients with type 2 diabetes just, while 17 registered those with weight problems; the mean age and body mass index of these clients were 57 years and 32, respectively, with the average research study period being 56 weeks.
- The endpoint was the distinction in the occurrence of NAION, as reported by detectives as a severe negative occasion.
TAKEAWAY:
- Of the 69 trials, just 5 reported cases of NAION– 8 cases in the GLP-1 group and 4 in the control group; the staying 64 trials did not report any case of NAION.
- Amongst the various GLP-1s, 6 cases were kept in mind in those utilizing semaglutide and one case each in those utilizing liraglutide and dulaglutide.
- GLP-1 treatment was not connected with an increased danger for NAION (chances ratio, 1.53; 95% CI, 0.53-4.44; P =.43).
- The approximated outright boost in the danger for NAION with GLP-1 treatment was 2.6 per 100,000 patient-years (however it was kept in mind that a boost of 570 per 100,000 patient-years would have been required to attain 80% analytical power).
IN PRACTICE:
“An appropriate boost of the relative danger for an extremely unusual, although serious, condition does not customize the total risk-benefit ratio of reliable drugs, a minimum of when properly recommended,” the authors composed. “At the exact same time, we need to know that the unsuitable usage of drugs for causing weight-loss in reasonably obese clients with low cardiovascular threat might be connected with uncommon however serious negative results, perhaps consisting of NAION,” they included.

RESTRICTIONS:
With such an unusual condition, the scientific trial numbers are not yet enough to show an association or develop the security of GLP-1s, specifically for semaglutide,
