Contemporary Concise Review 2024: Respiratory Infections

Area of Science:

• Infectious Diseases
• Public Health
• Geriatrics

Background:

• Resurgence of respiratory infections (influenza, RSV) globally post-COVID-19 relaxation.
• Emergence of antiviral resistance in influenza (I223V, S247N mutations) impacting neuraminidase inhibitor efficacy.
• Increased burden of RSV and pneumonia in the elderly, with concerns about declining physical function and aspiration pneumonia.

Purpose of the Study:

• To review current challenges in managing respiratory infections in a global context.
• To highlight issues with influenza vaccine effectiveness and antiviral resistance.
• To discuss the implications of infectious diseases in an aging population and clinical practice considerations.

Main Methods:

• Literature review and synthesis of current data on respiratory infections.
• Analysis of trends in drug resistance and vaccine efficacy.
• Discussion of clinical management and public health implications.

Main Results:

• Reduced susceptibility to influenza antivirals due to specific genetic mutations.
• Lower influenza vaccine effectiveness in older adults, prompting recommendations for high-dose vaccines.
• Growing prevalence of macrolide-resistant Mycoplasma and Bordetella pertussis strains.
• High disease burden of RSV in the elderly, with vaccination as a key preventive measure.
• Pneumonia frequently leads to functional decline in the elderly, increasing awareness for advance care planning.

Conclusions:

• Urgent need for updated strategies to combat resistant respiratory pathogens.
• Importance of tailored vaccination approaches for the elderly to mitigate disease burden.
• Necessity of advance care planning for pneumonia in super-aging societies.
• Ongoing debate regarding inhaled steroid use in bronchiectasis due to infection risk versus clinical efficacy.
