Abstract:
The incidence of secondary bacterial infections has increased in recent decades owing to various viral pandemics. These infections further increase the morbidity and mortality rates associated with viral infections and remain a significant challenge in clinical practice. Intensive antibiotic therapy has mitigated the threat of such infections; however, overuse and misuse of antibiotics have resulted in poor outcomes, such as inducing the emergence of bacterial populations with antimicrobial resistance (AMR) and reducing the therapeutic options for this crisis. Several antibiotic substitutes have been suggested and employed; however, they have certain limitations and novel alternatives are urgently required. This review highlights host immunomodulation as a promising strategy against secondary bacterial infections to overcome AMR. The definition and risk factors of secondary bacterial infections, features and limitations of currently available therapeutic strategies, host immune responses, and future perspectives for treating such infections are discussed.
Insights
Secondary bacterial infections pose a growing threat, exacerbated by viral pandemics. Host immunomodulation offers a promising strategy to combat antimicrobial resistance (AMR) and improve treatment outcomes.
Area of Science:
- Infectious Diseases
- Immunology
- Microbiology
Background:
- Secondary bacterial infections are increasingly prevalent, worsening outcomes of viral pandemics.
- Antibiotic overuse has led to antimicrobial resistance (AMR), limiting treatment options.
- Current antibiotic alternatives have limitations, necessitating novel therapeutic strategies.
Purpose of the Study:
- To review the challenges posed by secondary bacterial infections.
- To evaluate current therapeutic strategies and their limitations.
- To highlight host immunomodulation as a potential solution to overcome AMR.
Main Methods:
- Literature review of secondary bacterial infections.
- Analysis of host immune responses to bacterial infections.
- Evaluation of existing and novel therapeutic approaches.
Main Results:
- Secondary bacterial infections significantly increase morbidity and mortality.
- Antimicrobial resistance (AMR) is a major challenge due to antibiotic misuse.
- Host immunomodulation presents a viable alternative to antibiotics.
Conclusions:
- Host immunomodulation is a promising strategy to combat secondary bacterial infections and AMR.
- Further research into immune-based therapies is crucial.
- Developing new treatments is essential to address the limitations of current therapies.

Defense Against Bacterial Pathogens
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Factors Affecting the Risk of Infection
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...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
