Thrombotic and neuropsychiatric sequelae in post-coronavirus disease 2019 end-stage renal disease patients on maintenance hemodialysis

Abstract

Background End-stage renal disease (ESRD) patients on maintenance hemodialysis (MHD) are highly vulnerable to severe manifestations of coronavirus disease 2019 (COVID-19) as increased risk of thromboembolic disease and worsened neuropsychiatric status. Aim To assess the long-term thrombotic and neuropsychiatric sequelae of severe acute respiratory syndrome corona virus 2 in post-COVID-19 ESRD patients on MHD. Patients and methods We followed for 12 months, 35 clinically stable HD patients on MHD who were confirmed or highly suspected for COVID-19 by positive severe acute respiratory syndrome corona virus 2 RT-PCR and/or high probability on high-resolution computed tomography chest imaging. We recorded demographics, HD and COVID-19 related data, thromboembolic history, and psychiatric history. We recorded baseline and follow-up complete blood count with differential counts, D-dimer, prothrombin time, international normalized ratio, and high-resolution computed tomography chest findings. We assessed post-COVID-19 neuropsychiatric sequelae using the Arabic versions of Hamilton’s depression rating scale and Taylor’s manifest anxiety scale. Results Total leukocytic count, lymphocytes, and platelets were significantly lower during infection than preinfection, 6 months, and 1-year postinfection ( P <0.001, P =0.003, P =0.014, respectively). Six months after infection, d-dimer levels were higher than normal values. The incidence of vascular access thrombosis was 25.7%. The scores of Hamilton’s depression rating scale and Taylor’s manifest anxiety scale were high [25 (interquartile range; 17–28) and 26 (interquartile range; 19–33)], respectively, and the prevalence of depression and anxiety symptoms were 94.3 and 85.7%, respectively. Conclusions During infection, ESRD patients showed significantly lower total leukocytic count, lymphocytes, and platelets than preinfection, 6 months, and 1-year postinfection. They had high levels of d-dimer 6 months postinfection and a high risk for vascular access thrombosis. Their psychological wellbeing was markedly impaired by the pandemic resulting in depression and anxiety.
