Mortality rate was high in Hemodialysis (HD) patients. Our previous study suggested platelet counts might be a potential risk factor. However, few studies have examined the association of platelet count with mortality in HD patients. The aim is to examine if there is an association of thrombocytopenia (TP) with mortality and cardiovascular (CV) death in Chinese HD patients.


China DOPPS5 data was used. Fifty-eight of 1427 patients were excluded for missing platelet records. Demographic data, comorbidities, lab data, and death records were extracted. Participants were divided into 2 groups according to their platelet counts as TP group( platelet<100*10^9), and Non-TP group (platelet >=100*10^9). The Non-TP could not be further divided into normal or above normal groups as limited by the sample size. Associations between platelet counts and all-cause and CV mortality were analyzed using Cox regression models. Stepwise multivariate logistic regression was used to identify related impact factors.


Of 1369 patients, 201(14.7%) died and 102 (7.5%) died from CV disease. 11.2% (154) had TP at baseline. The mortality rates were 26.0% vs. 13.3% (p <0.01) in patients with and without TP. TP was associated with higher all-cause mortality after adjusted for covariates (HR:1.75, 95% CI: 1.12- 2.74), but was not associated with CV death after fully adjusted (HR: 1.75, 95% CI: 0. 89, 3.45, Figure 1). Multivariate logistic regression showed that Urine output <200 ml/day, cerebrovascular disease, hepatitis (B or C), and white blood cells were independent impact factors (P < 0.05).


Baseline TP is associated with higher risk of all-cause mortality in HD patients. Platelet counts may be used as early available outcome predictors among HD patients, though additional study is needed.
