Comprehensive Management Algorithm for Mycobacterium avium Complex Pulmonary Disease in the Real-World Setting | Annals of the American Thoracic Society The management of Mycobacterium avium complex pulmonary disease (MAC-PD) is challenging because of limited efficacy and frequent adverse events associated with standard treatments. The 2020 guidelines from the American Thoracic Society, European Respiratory Society, European Society of Clinical Microbiology and Infectious Diseases, and Infectious Diseases Society of America provide recommendations, but real-world adherence is often hindered by these issues, leading many patients to be unable to complete standard therapy. This review proposes a comprehensive management algorithm for MAC-PD, emphasizing multidisciplinary approaches and integrating nonantimicrobial management before, during, and after drug treatment to enhance patient outcomes. When a patient presents with chronic respiratory symptoms suggestive of nontuberculous mycobacteria, clinicians should follow a guideline-based approach to diagnosis, as diagnostic delays are common because of nonspecific symptoms. Proper evaluation should determine the disease phenotype (existence of cavitary lesions), as it influences treatment choices. Airway clearance, nutritional support, and management of underlying conditions are essential nonantimicrobial components. Regular outpatient monitoring helps detect disease progression and optimize treatment. Treatment strategies vary based on disease severity. For noncavitary nodular bronchiectatic disease, a thrice-weekly regimen is preferred because of better tolerability. Severe cases or those with cavitary forms may require daily treatment with additional aminoglycosides. Amikacin liposome inhalation suspension is recommended for patients not responding to standard regimens after 6 months. Recent research addresses drug intolerance, suggesting alternatives such as a two-drug regimen without rifamycin in certain cases. Consultation with nontuberculous mycobacteria specialists is advised for complex cases, particularly those with macrolide resistance or requiring surgical intervention. The algorithm emphasizes shared decision making, patient education, and family support to improve adherence and outcomes. https://tinyurl.com/2u845twd
