Warning signs and severe dengue in end stage renal disease dialysis patients.

ABSTRACT

BACKGROUND/PURPOSE: The 2009 WHO guideline established warning signs (WS) to predict severe dengue (SD). However, their positive predictive value has been found to be low in the general adult population, but they might be higher in a different population. This study investigated the association between WS and SD in end stage renal disease (ESRD) patients on maintenance dialysis in Taiwan where both diseases are prevalent. METHODS: This study enrolled ESRD dialysis patients with dengue in 2015. Demographic, laboratory data, symptoms/signs and complication of dengue were retrospectively collected from medical records at our hospital. RESULTS: Of 49 ESRD patients with dengue, 44 patients were receiving hemodialysis and 5 peritoneal dialysis. Older patients (>65 years old) tended to have the WS(56% vs 16.7%, P = 0.007). The rate of hospitalization, intensive care unit admission and in-hospital mortality was 79.6%, 22.5%, and 8.2%, respectively. Eighteen patients (36.7%) presented WS and eighteen patients (36.7%) developed to SD, including ten with plasma leakage, twelve with hemorrhage, and six with organ failure. Patients with WS were seven times more likely to develop SD than those without (OR 7.06; 95%CI 1.34-37.21). WS was associated with plasma leakage (OR 12.36; 95% CI 1.56-97.74) and severe hemorrhage (OR 5.1; 95% CI 1.03-25.18), but not organ failure. CONCLUSIONS: Prevalence of SD is high in ESRD dialysis patients. The presence of WSs in this group was highly correlated with SD. Thus, more attention should be paid to treating ESRD patients with dengue fever if they present WSs.
