Factors related to mortality in patients with stage 5 chronic kidney disease on dialysis with COVID-19: An exploratory case series analysis.

Introduction: Different studies describe the clinical profile and factors that could explain the evolution and outcome of patients with chronic kidney disease and COVID-19. This study aims to evaluate the factors related to the mortality of patients with stage-5 chronic kidney disease on chronic dialysis hospitalized for COVID-19 at the Hospital Nacional Arzobispo Loayza from April to December 2020.

Methods: Retrospective case series and exploratory analysis were performed.

Higher prevalence of unrecognized kidney disease at high altitude.

Background: High altitude renal syndrome has been described in populations with excessive erythrocytosis. We evaluated whether high altitude (HA) dwellers might be at increased risk for kidney disease.

Methods: We performed a cross-sectional study to investigate differences in prevalence of kidney function and metabolic syndrome in healthy subjects living at HA vs.

High altitude renal syndrome (HARS).

More than 140 million people live permanently at high altitude (>2400 m) under hypoxic conditions that challenge basic physiology. Here we present a short historical review of the populating of these regions and of evidence for genetic adaptations and environmental factors (such as exposure to cobalt) that may influence the phenotypic responses. We also review some of the common renal physiologic responses focusing on clinical manifestations.
