This review highlights advances in cystic fibrosis (CF) airway infections, including guidelines for nontuberculous mycobacteria and antibiotic strategies. Early detection and treatment of resistant bacteria and fungi like Aspergillus fumigatus remain critical for CF patient care.
Area of Science:
- Pulmonary Medicine
- Infectious Diseases
- Microbiology
Background:
- Cystic Fibrosis (CF) airway infections present complex challenges.
- Emerging antibiotic resistance and fungal coinfections require updated management strategies.
Purpose of the Study:
- To review recent advancements in the diagnosis and treatment of CF airway infections.
- To provide insights into managing nontuberculous mycobacteria and resistant bacterial strains.
- To emphasize the importance of fungal detection in CF airways.
Main Methods:
- Literature review of recent studies and international guidelines.
- Analysis of data on antibiotic efficacy and resistance patterns.
- Discussion of emerging pathogens and their clinical implications.
Main Results:
- International guidelines for nontuberculous mycobacteria care are available.
- Azithromycin and combination antibiotics show benefits.
- Multiresistant bacteria, including Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus (MRSA), are a concern.
- Levofloxacin demonstrates efficacy but requires further study regarding microbiota impact and resistance.
- Aspergillus fumigatus is an under-recognized fungal pathogen in CF airways.
Conclusions:
- Current strategies focus on early diagnosis and eradication of key pathogens.
- Antibiotic choices like levofloxacin offer new options but necessitate careful monitoring.
- Fungal screening, particularly for Aspergillus fumigatus, is crucial for comprehensive CF care.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

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...
Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
