Clinical characteristics and functional dependent risk of intracerebral hemorrhage in patients with nephrotic syndrome

BACKGROUND: While an increased incidence of intracerebral hemorrhage (ICH) has been reported in patients with nephrotic syndrome (NS), comprehensive understanding of the characteristics of ICH in this population remains elusive. This study explored the clinical features of ICH in a larger cohort of NS patients.

METHODS: To compare the clinical characteristics of ICH in patients with and without NS, we conducted a multi-institutional retrospective cohort study using the data from Chang Gung Research Database of Taiwan from January 1, 2001, to December 31, 2017.

RESULTS: This study enrolled a total of 120 ICH patients with NS, and 271 ICH patients without NS. Patients with NS had a longer average length of stay in the acute medicine ward (17.7 ± 15.9 days vs 14.4 ±13.3 days, P = 0.047) and higher incidence of urinary tract infection (20.0% vs 10.0%, P = 0.006), gastrointestinal bleeding (16.7% vs 4.8%, P < 0.001), and pulmonary edema (4.2% vs 0%, P = 0.003) compared to those without ICH. Furthermore, the risk of 30-day dependent outcome (modified Rankin Scale score≧3) was significantly higher in ICH patients with NS compared to those without NS (Odds ratio 3.43, 95% confidence interval 1.49 to 7.91, P = 0.004). However, the 30-day mortality rate was similar between the NS patients and the control group.

CONCLUSIONS: NS is associated with a significantly increased risk of functional dependence following ICH, highlighting the critical need for tailored intensive treatment and rehabilitation specifically for this patient population.
