An in-depth analysis of nearly two dozen studies sheds light on the heightened cardiovascular risk associated with nephritis among patients with systemic lupus erythematosus (SLE). The meta-analysis, comprising 22 studies and over 8600 SLE patients, reveals compelling insights into the additional cardiovascular burden faced by those with lupus nephritis (LN).

Published findings indicate that the presence of LN in SLE patients significantly increases the likelihood of cardiovascular risk factors, including dyslipidemia, diabetes, and hypertension. Moreover, individuals with LN experience a threefold rise in cardiovascular mortality incidence compared to those without nephritis. These observations underscore the critical need for proactive management of cardiovascular health in SLE patients, particularly those with nephritis.

Desmond YH Yap, MD, PhD, leading the investigative team, emphasizes the clinical significance of these findings. The study highlights the potential modifiability of cardiovascular risk factors through effective treatment, offering a pathway to mitigate the risk of cardiovascular morbidity and mortality among SLE patients with LN.

As the most common form of lupus, SLE affects millions worldwide, with cardiovascular disease emerging as a leading cause of mortality in these patients. Against this backdrop, the study aims to elucidate how LN influences cardiovascular risk factors and complications in SLE patients.

The systematic review and meta-analysis encompassed studies spanning from 1947 to 2022, retrieved from prominent medical databases. Out of over 26,000 initially identified studies, 22 were included in the final meta-analysis, covering a diverse cohort of SLE patients with and without LN.

Results from the meta-analysis reveal a stark contrast in cardiovascular risk profiles between SLE patients with and without nephritis. Patients with LN exhibited significantly higher rates of hypertension, hyperlipidemia, and diabetes mellitus. While trends toward increased myocardial infarction and cerebrovascular events were noted among LN patients, the association did not reach statistical significance.

Furthermore, the analysis underscores the elevated incidence of cardiovascular mortality among SLE patients with nephritis, highlighting the imperative of intensified cardiovascular surveillance and management in this population.

Despite the comprehensive insights offered by the meta-analysis, certain limitations warrant consideration. These include the scarcity of studies with comprehensive cardiovascular data, incomplete outcome definitions, and inherent biases associated with mortality analyses.

In conclusion, the study underscores the critical importance of proactive cardiovascular risk management in SLE patients, particularly those with LN. By addressing modifiable risk factors and implementing targeted interventions, clinicians can strive to mitigate the burden of cardiovascular disease and enhance long-term outcomes in this vulnerable patient population.
