Insights

Asymptomatic COVID-19 infection is prevalent in hemodialysis patients, with 12.8% testing positive. These patients face increased risks of hypercoagulability and thromboembolic complications, necessitating stricter infection control.

Area of Science:

  • Nephrology
  • Infectious Diseases
  • Hematology

Background:

  • Coronavirus disease 2019 (COVID-19) presents varied clinical symptoms.
  • End-stage renal disease (ESRD) patients on hemodialysis (HD) require specific infection control.
  • Humoral response data in ESRD HD patients with SARS-CoV-2 is limited.

Purpose of the Study:

  • To determine the prevalence of asymptomatic SARS-CoV-2 infection in ESRD HD patients.
  • To investigate clinical and laboratory differences between infected and non-infected HD patients.
  • To assess the risk of hypercoagulability in this population.

Main Methods:

  • Screened 179 asymptomatic ESRD HD patients for COVID-19.
  • Confirmed SARS-CoV-2 infection using real-time RT-PCR.
  • Analyzed demographic and laboratory data, including C-reactive protein, lymphocyte counts, platelet counts, TAT, and D-dimer levels.

Main Results:

  • 12.8% (23/179) of asymptomatic HD patients tested positive for SARS-CoV-2.
  • Significant differences observed in C-reactive protein, lymphocytes, and platelet counts between positive and negative groups.
  • Elevated TAT and D-dimer levels were noted in the COVID-19 positive group, indicating hypercoagulability.

Conclusions:

  • Asymptomatic SARS-CoV-2 infection is present in hemodialysis patients.
  • HD patients with COVID-19 are at risk for hypercoagulability and thromboembolic complications.
  • Enhanced infection control and proactive diagnosis are crucial for managing COVID-19 in HD patients.

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Hemodialysis I: Introduction01:25

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Hemodialysis III: Nursing Management

The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
