Abstract:

Despite the recommendations to avoid using corticosteroids systematically for hospitalized coronavirus disease of 2019 (COVID-19) patients, healthcare professionals used personalized treatments, including corticosteroids, as adjuncts to treat their patients due to their limited access to treatment options. This study aims to evaluate the use of corticosteroids among hospitalized COVID-19 patients with all-cause mortality as the primary outcome and to assess the predictors of all-cause mortality associated with the characteristics of the patients and the corticosteroid regimens adopted.

Methods:

A multicenter retrospective study was performed over three months targeting 422 COVID-19 patients from six hospitals in Lebanon. Data were collected from patients' medical charts retrospectively and covered a period of one year (September 2020-August 2021).

Results:

The study sample included 422 patients, predominantly males, with 59% of cases classified as severe or critical cases. Dexamethasone and methylprednisolone were the most used corticosteroids. Around 22% of the patients died during hospitalization. After adjusting for covariates, performing a polymerase chain reaction before admission increased the mortality rate by 424% compared to doing it at hospital admission (aHR 4.24, 95% CI 1.35-13.3), with 18.11 times higher mortality rate among critical cases (aHR 18.11, 95% CI 9.63-31.05). Exposure to side effects from corticosteroids increased the mortality rate by 514% compared to others (aHR 5.14, 95% CI 1.28-8.58). In particular, the mortality rate among patients having hyperglycemia dropped by 73% compared to others (aHR 0.27, 95% CI 0.06-0.98).

Conclusion:

Corticosteroids are frequently used in treating hospitalized COVID-19 patients. The all-cause mortality rate was higher among older and critical cases and lower among smokers and those treated for more than 7 days. Research exploring the safety and efficacy of corticosteroids is required to allow better in-hospital management of COVID-19 cases.

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Pulmonary Tuberculosis I

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

COPD: Pathogenesis and Clinical Features

COPD: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
