Insights

Mild and moderate COVID-19 did not significantly impact hearing function in recovered patients. This study found no permanent changes in hearing thresholds after infection or treatment.

Area of Science:

  • Otolaryngology
  • Infectious Diseases
  • Audiology

Background:

  • COVID-19 has been associated with various symptoms, including potential auditory complications.
  • Understanding the long-term effects of mild to moderate COVID-19 on hearing is crucial for patient management.

Purpose of the Study:

  • To evaluate the hearing function in individuals who experienced mild to moderate COVID-19.
  • To determine if COVID-19 infection or its treatment causes permanent hearing impairment.

Main Methods:

  • Included hospital staff recovered from mild/moderate COVID-19, excluding those with pre-existing ear conditions or severe illness.
  • Conducted pure tone audiometry to assess hearing thresholds (HT) in 101 participants.
  • Compared pre- and post-COVID-19 audiograms for 31 participants (Group 1) and documented HTs for 70 participants without prior audiograms (Group 2).

Main Results:

  • No statistically significant changes in hearing thresholds were observed in Group 1 participants after COVID-19.
  • Participants in Group 2 had pure tone averages below 25 dB, indicating no significant hearing loss.
  • Subgroup analyses based on symptoms and medications also showed no significant differences in hearing function.

Conclusions:

  • Mild and moderate COVID-19 infections do not lead to permanent hearing function impairment.
  • Current treatments for mild to moderate COVID-19 also appear to have no lasting negative effects on hearing.

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Chronic Obstructive Pulmonary Disease01:22

Chronic Obstructive Pulmonary Disease

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

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...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
