Apolipoprotein L1 (APOL1) and the risk of adverse renal outcomes in patients of African ancestry with systemic lupus erythematosus

LupusPublished Retrospective cohort study

Authors' conclusion

The higher prevalence of renal and hypertensive disorders in SLE patients of AA compared to those of EA is not fully explained by the presence of APOL1 high risk variants.

Study context

Population
Patients with systemic lupus erythematosus (SLE) of European and African ancestry in a genetic biobank linked to de-identified electronic health records
Participants
784 patients
Exposure
SLE patients of African ancestry vs European ancestry, including and excluding APOL1 high-risk genotypes
  • African ancestry (AA)n = 195
  • AA with APOL1 HRn = 27
Outcome
Prevalence of renal and hypertensive-related disorders by ancestry, including and excluding patients with APOL1 HR genotype
Methodological detailsgenetic biobank linked to de-identified electronic health records, phenome-wide association approach, logistic regression
  • Genetic biobank linked to de-identified electronic health records
  • Phenome-wide association approach
  • Logistic regression

Main finding

As reported in the abstract

Eighteen renal and hypertensive-related phenotypes were more common in AA than European ancestry (EA) patients
18

Observational data: associations, not effects.
