Abstract
Introduction: Lupus nephritis (LN) is a severe manifestation of systemic
lupus erythematosus (SLE), with its incidence and progression potentially
influenced by structural socioeconomic inequalities. The Population
Renal Health paradigm (Burgos-Calderón, Depine, and Aroca-
Martínez, 2021) shifts from individual risk assessment to population
and territorial vulnerability analysis by integrating social determinants
of health (SDOH). To operationalize this approach, the Population
Vulnerability Index (PVI) was developed as a quantitative geospatial
tool that measures SDOH across the Colombian Caribbean region,
enabling systematic comparison of territorial vulnerability. In parallel,
the RENELUP registry collects and georeferences LN cases throughout
Colombia. This study cross-references RENELUP data from the city of
Barranquilla with PVI scores to examine how SDOH influence disease
distribution patterns in this urban setting.
