Local hyperthermia therapy for refractory cutaneous Mycobacterium marinum infection

Treatment of non-tuberculosis mycobacteria skin infections

Non-tuberculosis mycobacteria (NTM) skin infections have become increasingly prevalent in recent years, presenting a unique challenge in clinical management. This review explored the complexities of NTM infections localized to the superficial tissues and provided valuable insights into the optimal therapeutic strategies. The antibiotic selection should base on NTM species and their susceptibility profiles. It is recommended to adopt a comprehensive approach that considers the unique characteristics of superficial tissues to improve treatment effectiveness and reduce the incidence of adverse reactions, infection recurrence, and treatment failure. Infection control measures, patient education, and close monitoring should complement the treatment strategies to achieve favorable outcomes in managing NTM skin infections. Further efforts are warranted to elucidate factors and mechanisms contributing to treatment resistance and relapse. Future research should focus on exploring novel treatment options, innovative drug development/delivery platforms, and precise methodologies for determining therapeutic duration. Longitudinal studies are also needed to assess the long-term safety profiles of the integrated approaches.

The combination of photodynamic therapy and fractional CO2 laser for mycobacterium marinum infection

Mycobacterium marinum (M. marinum) can cause cutaneous infection. Therapy with active antibiotics for 3 to 6 months is one reasonable treatment. However, it is hard to provide an optimal balance with regard to efficacy and tolerability when the patient is complicated with other diseases. We reported two patients with cutaneous M. marinum infections who were successfully treated with 5-aminolevulinic acid-photodynamic therapy (5-ALA-PDT) combined with fractional CO2 laser ablation. The results of these two cases indicated that PDT in combination with fractional CO2 laser ablation of epidermis could be a therapeutic option for the treatment of skin infections caused by M. marinum.
