Association between a novel inflammation-lipid composite marker CRP/HDL and erectile dysfunction: evidence from a large national cross-sectional study

Background

Erectile dysfunction (ED) is one of the most common male sexual disorders, closely associated with both inflammation and lipid dysregulation. Recently, a novel inflammation-lipid composite marker, CRP/HDL, has been proposed to integrate the impact of both pathways on health, yet its relationship with ED remains unexplored. Therefore, our study aimed to investigate the potential association between the CRP/HDL ratio and ED.

Methods

We utilized data from the NHANES database, known for its comprehensive and high-quality information. A total of 3,633 eligible participants from the 2001-2004 cycles were included. ED was assessed using a single-item questionnaire, while CRP and HDL were measured from blood samples. Multivariable regression analyses were performed to evaluate the association between CRP/HDL and ED after adjusting for potential confounders. Additionally, subgroup and sensitivity analyses were conducted to test the robustness of the results, and the linear trend between CRP/HDL and ED was visualized through smooth curve fitting.

Results

Among the 3,633 participants, 1,027 had a history of ED. The CRP/HDL ratio was significantly higher in participants with ED compared to those without (10.53 ± 0.69 vs. 7.43 ± 0.35, P<0.001). In the regression analysis, a higher continuous CRP/HDL ratio was significantly associated with increased ED risk even after full adjustment (OR: 1.17, 95% CI: 1.05, 1.30; P = 0.01). Compared to Q1 of the CRP/HDL ratio, participants in Q2, Q3, and Q4 had progressively higher ED risks: Q2 (OR: 1.40, 95% CI: 1.01, 1.95; P = 0.05), Q3 (OR: 1.58, 95% CI: 1.10, 2.27; P = 0.02), and Q4 (OR: 1.85, 95% CI: 1.31, 2.60; P = 0.005), showing a clear linear trend. Subgroup analyses indicated consistent results across various populations with no significant interactions, and sensitivity analysis revealed that the CRP/HDL ratio also increased the risk of severe ED (OR: 1.14, 95% CI: 1.03, 1.26; P = 0.02).

Conclusion

This is the first study to establish a significant positive association between an elevated CRP/HDL ratio and ED risk, suggesting its potential role in screening for ED risk and guiding timely interventions. However, further large-scale studies are needed to confirm our findings and explore the underlying mechanisms.

Effects of diet and antihyperglycemic drugs on erectile dysfunction: A systematic review

BACKGROUND

Erectile dysfunction is recognized as one of the complications of diabetes mellitus. To date, a wide gap of knowledge is present on the efficacy of pharmacological treatments of diabetes mellitus on erectile function, acting not only through metabolic control. Similarly, the effects of different diet regimens on erectile dysfunction are still debated.

OBJECTIVES

We aimed to explore the effects of diet and antihyperglycemic drugs, considering both old and novel therapeutic approaches, on erectile function.

MATERIALS/METHODS

We performed a systematic review, following the PRISMA guidelines. The research was conducted on studies reporting erectile dysfunction assessment in subjects with diabetes and the relationship with diet and antihyperglycemic drugs.

RESULTS

The Mediterranean diet was effective in most studies for the protection of erectile function. Furthermore, antihyperglycemic drugs seem to show an overall protective role on erectile function.

DISCUSSION/CONCLUSION

Although encouraging results are present for all classes of antihyperglycemic drugs, several studies are needed in humans, mainly on acarbose, pioglitazone, dipeptidyl-peptidase-4 inhibitors, and sodium-glucose cotransporter-2 inhibitors.

Vasculogenic Erectile Dysfunction: The Impact of Diet and Lifestyle

Vasculogenic erectile dysfunction has been aptly called the "canary in the coal mine" for cardiovascular disease because it almost always precedes other manifestations of atherosclerotic cardiovascular disease, including myocardial infarction and stroke. It is common, associated with the presence of modifiable cardiovascular risk factors, and impacted by diet and lifestyle choices. This concise review provides an update on the use of dietary and other lifestyle interventions to improve vasculogenic erectile dysfunction and atherosclerotic cardiovascular disease.
