Acute KIDnEy Injury in CoviD-19 (AIDED)

March 18, 2025 updated by: University Hospitals of Derby and Burton NHS Foundation Trust

Long-term Outcomes After Acute Kidney Injury in Coronavirus Disease (COVID-19)

This is a prospective observational parallel group cohort study that will aim to recruit 220 participants who were admitted to the hospital with COVID-19 between 1st March 2020 and 30th June 2020 (Group A - 110 participants who had COVID-19 with AKI; Group B - 110 participants who had COVID-19 without AKI). Data from groups A and B will be compared with AKI and non-AKI groups from an existing study database (ARID study, n=1125) who were recruited before the outbreak of the COVID-19 pandemic (recruitment 2013-2016) and who have all completed at least three years of follow up. Participants who have recovered from COVID-19 will be matched for analysis to participants from the ARID study for AKI status, baseline estimated glomerular filtration rate (eGFR) stage, age (± 5 years) and presence of diabetes. Potential participants will receive a letter of invitation along with a comprehensive participant information sheet (PIS).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

After the participants have read and understand the PIS, and had sufficient time (at least 24 hours) to consider their participation in this study, the investigators will ask them to sign a consent form, which shows their willingness to take part. The investigators will then collect information from their medical records about their hospital admission with COVID-19, including their age, ethnicity, medical conditions, length of hospital stay, tablets or any other treatments they received, as well as details of their stay in the intensive care unit.

For the two groups - COVID AKI and COVID non-AKI, telephone follow-up with a study questionnaire will be performed at recruitment, 6-9 months and 12-15 months after hospital discharge. The study questionnaire will include the following:

  1. Details of any medical event and date of medical event since last study follow-up.
  2. Details of any hospital re-admission.
  3. Details of current medication.

In addition, at the same time points, participants will be asked to attend their general practitioner surgery or other clinic to have simple clinical measurements (height, weight and blood pressure), blood and urine tests.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

People who were admitted to the hospital with COVID-19:

  • Group A: people who had COVID-19 with AKI.
  • Group B: people who had COVID-19 without AKI.

Description

Inclusion Criteria:

  1. Adult patients greater or equal to 18 years of age.
  2. Swab results positive for SARS-CoV-2.
  3. Patients admitted to the hospital for ≥24hrs.

Exclusion Criteria:

  1. Paediatric patients as defined by age of <18 years of age.
  2. Patients >90 years of age.
  3. Swab results negative for SARS-CoV-2.
  4. Patients on haemodialysis or peritoneal dialysis, pre-existing CKD stage 5 (eGFR <15ml/min/1.73m2), solid organ transplant.
  5. Inability/refusal to give informed consent to participate.
  6. Death during the same hospital admission that AKI occurred.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of kidney disease progression at 12 months.
Time Frame: 12 months after hospital discharge.
Kidney disease progression will be defined as a decline in estimated glomerular filtration rate (eGFR; ml/min/1.73m2) of ≥30%
12 months after hospital discharge.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
