After applying inclusion and exclusion criteria, 169 patients were finally enrolled, comprising 80 cases of HSP and 89 cases of HSPN confirmed by renal biopsy.

The diagnostic efficacy was further improved when these parameters were combined (AUC\u2009=\u20090.95). Multivariate logistic regression analysis identified Emean, Vmean, urinary white blood cell count, and serum albumin as independent predictors of HSPN. Notably, the HSPN group showed significantly higher age and body mass index (BMI) compared to the HSP group. Importantly, viscosity parameters (Vmean) demonstrated significant correlations with white blood cell count (WBC;\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u20090.238,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u2009.002) and albumin levels (\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u2009\u22120.274,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u2009.001), suggesting its favorable sensitivity in reflecting inflammatory activity.
