Insights
Cytomegalovirus (CMV) reactivation was detected in 11.42% of severe COVID-19 patients, particularly those in the ICU. Early detection of CMV DNA in blood is crucial for better patient outcomes.
Area of Science:
- Infectious Diseases
- Virology
- Critical Care Medicine
Background:
- Severe COVID-19 is associated with various complications, including opportunistic infections.
- Cytomegalovirus (CMV) reactivation is a known concern in immunocompromised individuals.
Approach:
- A point prevalence study was conducted on 140 hospitalized patients with severe COVID-19.
- CMV DNA in peripheral blood was determined using PCR.
- Clinical data, including corticosteroid use and ICU admission, were analyzed.
Key Points:
- CMV reactivation (CMV DNA presence) was observed in 11.42% of severe COVID-19 patients.
- ICU patients showed a significantly higher prevalence (29.7%) compared to general ward patients (4.85%).
- Higher corticosteroid doses were associated with CMV reactivation (p < 0.001).
- CMV reactivation was often clinically unsuspected and linked to increased nosocomial infections and worse prognosis.
Conclusions:
- Systematic screening for CMV reactivation is recommended for severe COVID-19 patients admitted to the ICU.
- Early identification and management of CMV coinfection may improve outcomes in severe COVID-19.
Objective:
To determine the prevalence of CMV reactivation in a population admitted for severe COVID-19 to a general hospital.
Methods:
Point prevalence study in all hospitalized patients with severe COVID-19 (admitted either to general wards or ICU). Determination of the presence of CMV DNA in circulating blood. COVID-19 was confirmed in patients with compatible clinical manifestations, usually with pneumonia and a positive nasopharyngeal PCR test.
Results:
We included 140 hospitalized patients with COVID-19 who consented to participate. A total of 16 patients (11.42%), had circulating CMV-DNA in peripheral blood at the time of the study. Patients with positive CMV viral load were mainly ICU patients (11/37 -29,7%) and only 5/103 cases (4,85%) were hospitalized into general wards. The accumulated doses of corticosteroids (prednisone equivalents) in the study day were (median and IQR) 987.50 mg (396.87-2,454.68) and 187.50 mg (75.00-818.12) respectively in CMV positive and negative patients (p < 0.001). A significant proportion of CMV positive patients were discovered because of the study and were clinically unsuspected by their physicians. The coinfected COVID-CMV positive population had a higher risk of accumulated secondary nosocomially-acquired infections and a worse prognosis.
Conclusions:
CMV reactivation should be systematically searched in patients in COVID-19 cases admitted to the ICU.

Myocarditis III: Medical Management
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Acute Respiratory Failure-III
Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
