Pulmonary CT findings in end-stage kidney disease (ESKD) patients with suspected COVID-19 were analyzed. Atypical chest CT patterns in these patients cannot rule out COVID-19, highlighting diagnostic challenges.
Area of Science:
- Nephrology
- Pulmonology
- Infectious Diseases
- Radiology
Background:
- End-stage kidney disease (ESKD) patients frequently experience lung diseases, complicating COVID-19 diagnosis.
- Pulmonary chest tomography (CT) is crucial for evaluating lung conditions in ESKD patients undergoing renal replacement therapy (RRT).
Purpose of the Study:
- To describe and analyze pulmonary CT findings in hospitalized ESKD patients with suspected COVID-19.
- To assess the diagnostic utility of CT patterns in differentiating COVID-19 in ESKD patients on RRT.
Main Methods:
- Retrospective analysis of 109 hospitalized ESKD patients (age >18) with suspected COVID-19.
- Classification of pulmonary CT findings into typical, indeterminate, atypical, or negative patterns.
- Comparison of CT patterns between COVID-19-positive and COVID-19-negative groups.
Main Results:
- The study included 109 patients, with 62.3% testing positive for COVID-19; the most common CT finding was ground glass opacities.
- Typical CT patterns were significantly more prevalent in COVID-19-positive patients (61%) compared to negative patients (0%, p < 0.001).
- Atypical CT patterns were more frequent in COVID-19-negative patients (56%), while typical patterns had 60.61% sensitivity and 100% specificity.
Conclusions:
- Atypical chest CT patterns in hospitalized ESKD patients on RRT do not exclude a COVID-19 diagnosis.
- The study underscores the complexity of diagnosing COVID-19 in ESKD patients, necessitating careful clinical correlation with imaging findings.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
