Report of human nocardiosis in Italy between 1993 and 1997

Area of Science:

• Medical Microbiology
• Infectious Diseases
• Epidemiology

Background:

• Nocardiosis, a rare bacterial infection, presents diagnostic challenges.
• Prompt diagnosis and treatment are crucial for favorable patient outcomes.
• Previous studies on Nocardia spp. infections in Italy are limited.

Purpose of the Study:

• To report on the incidence and species distribution of nocardial infections in Italy.
• To emphasize the diagnostic difficulties associated with Nocardia infections.
• To advocate for a national surveillance network for nocardiosis.

Main Methods:

• Retrospective analysis of 26 patients diagnosed with nocardial infection.
• Data collected from hospitals across 11 Italian cities between 1993 and 1997.
• Identification of Nocardia species involved in the diagnosed cases.

Main Results:

• Nocardia asteroides was the most common pathogen (18 cases).
• Other identified species included Nocardia farcinica (5 cases), Nocardia nova (2 cases), and Nocardia brasiliensis (1 case).
• All cases presented diagnostic difficulties, underscoring the need for heightened clinical suspicion.

Conclusions:

• Nocardial infections require a high index of suspicion for early diagnosis.
• The findings support the establishment of a permanent national network for nocardiosis surveillance in Italy.
• Improved surveillance can facilitate timely therapeutic interventions and better patient management.
