Key Takeaway
Consider semaglutide for weight loss and blood pressure management in non-diabetic patients with obesity and CKD.

This meta-analysis evaluated the effects of semaglutide on body mass index (BMI), blood pressure, and renal function in a population of 430 non-diabetic patients with obesity and comorbid chronic kidney disease (CKD) or hypertension. The analysis synthesized data from a randomized controlled trial, an observational study, and a post hoc analysis.

The meta-analysis reported significant BMI reductions across included studies: Tuttle 18.3%, Apperloo 11.8%, and Vanek 1.5% (P = 0.001). Additionally, semaglutide improved hypertension control (SBP <130 mmHg) with results of Apperloo 20.6%, Vanek 12.5%, and Tuttle 17.6% (P < 0.02). Renal function, measured by eGFR >30 ml/min/1.73m², increased from baseline in all studies: Apperloo 65.8%, Vanek 4.83%, and Tuttle 36.4% (P < 0.001).

The treatment was reported as well-tolerated. However, the inclusion of non-randomized studies, including an observational study and a post hoc analysis, means that causality cannot be strictly determined for the pooled results across all study types. These findings suggest semaglutide is effective for managing weight and blood pressure in patients with obesity and CKD.

How this fits prior evidence

This meta-analysis extends the evidence regarding incretin-based therapies (IBTs) previously noted to outperform placebo for weight loss and glycemic control in type 2 diabetes. While the previous finding focused on diabetic populations, this study specifically addresses non-diabetic patients with obesity and CKD or hypertension, providing data on renal function improvements (eGFR increase of up to 65.8%) and blood pressure management.

A recent meta-analysis involving 430 non-diabetic patients explored the impact of semaglutide on those struggling with obesity, hypertension, and chronic kidney disease. The findings suggest that this medication provides significant benefits beyond just weight management.

The study observed substantial reductions in body mass index across different trials. Additionally, patients showed marked improvements in blood pressure control, which is critical for managing long-term cardiovascular health and preventing further complications from hypertension.

Most importantly, the data indicated a notable improvement in renal function markers. Patients experienced an increase in estimated glomerular filtration rates, suggesting that semaglutide may play a protective role for kidney health in patients with existing chronic conditions.

While the study included various types of trials, the results consistently show that semaglutide is well-tolerated. These findings support its potential use as a versatile treatment option for managing complex comorbidities like obesity and renal impairment simultaneously.

What this means for you:
Semaglutide effectively reduces BMI and improves kidney function in patients with obesity and chronic kidney disease.

Common questions

Is semaglutide safe for people with kidney disease?

In this analysis of 430 non-diabetic patients with obesity and CKD or hypertension, semaglutide was reported as well-tolerated. However, the analysis did not report specific adverse events or serious side effects. Always talk to your doctor about risks and benefits for your individual health.

How much weight loss can I expect with semaglutide?

The analysis found BMI reductions ranging from 1.5% to 18.3% across different studies, with an overall significant decrease (P = 0.001). The exact amount varies by person and study. Your doctor can help set realistic expectations based on your health.

Does semaglutide help with blood pressure?

Yes, the analysis showed improved hypertension control. In one study, 20.6% of patients reached systolic blood pressure under 130 mmHg, with similar results in other studies (12.5% and 17.6%). The overall improvement was statistically significant (P < 0.02).

Can semaglutide improve kidney function?

The analysis found that kidney function, measured by eGFR, increased from baseline in all three studies. For example, one study showed a 65.8% increase, another 4.83%, and a third 36.4%. The overall result was significant (P < 0.001). However, the analysis included non-randomized studies, so causality is not certain.

BACKGROUND: Semaglutide, a GLP-1 receptor agonist, has demonstrated metabolic and renal benefits in diabetic populations. However, its efficacy and safety in non-diabetic individuals with obesity and chronic kidney disease (CKD) remain largely unstudied. Given the high cardiometabolic risk in this group and limited therapeutic options, evaluating semaglutide's role is crucial. OBJECTIVE: To assess the effects of semaglutide on body mass index (BMI), blood pressure, renal function (eGFR), and albuminuria in non-diabetic patients with obesity and CKD or hypertension. METHODS: This systematic review and meta-analysis was conducted in accordance with PRISMA guidelines. A total of 580 studies were screened; 3 eligible studies (n=430 participants) were included. Data were extracted from a randomized controlled trial, a real-world observational dialysis study, and a large post hoc trial analysis. Fixed-effect meta-analysis models were applied to estimate pooled effects on BMI, systolic blood pressure (SBP), and renal outcomes. RESULTS: Semaglutide treatment significantly reduced BMI (mean reduction: Tuttle 18.3%, Apperloo 11.8%, Vanek 1.5%; P = 0.001), and improved hypertension control (SBP <130 mmHg: Apperloo 20.6%, Vanek 12.5%, Tuttle 17.6%; P < 0.02). Renal function also improved, with eGFR >30 ml/min/1.73m² increasing from baseline in all studies (Apperloo 65.8%, Vanek 4.83%, Tuttle 36.4%; P < 0.001). No publication bias was detected. CONCLUSIONS: Semaglutide is effective and well-tolerated in non-diabetic patients with obesity and CKD, resulting in significant weight loss, better blood pressure control, and improved renal parameters. These findings support its expanded use in non-diabetic CKD populations, including dialysis-dependent individuals.
