Clinical spectrum and outcome of Nocardia infection: experience of 15-year period from a single tertiary medical center.

Abstract

INTRODUCTION:

Nocardiosis, although very rare, is considered as an important opportunistic infection; however, recent literature is limited. This study describes all cases of nocardial infection treated in the authors' hospital to provide more information about clinical manifestations, species isolated, treatment and outcome of patients with nocardiosis.

METHODS:

A retrospective review of the clinical features and outcome of nocardial infections was conducted during a 15-year period (1996-2010) at Rambam Health Care Campus.

RESULTS:

The study included 53 patients with nocardial infection, 43 of them had underlying immunodeficiency. The most common clinical form was pulmonary nocardiosis with and without dissemination (60%), followed by skin and soft tissue infection (21%), bacteremia (11%) and pertonitis (5%). Resistance to trimethoprim/sulfamethoxazile was detected in 15% of isolates; to imipenem in 5% and to ciprofloxacin in 65%. Overall mortality was 25% (13/53), mainly observed in patients with pulmonary involvement (37.5%).

CONCLUSIONS:

Nocardiosis is a rare infection and mainly affects immunocompromised patients. Higher index of suspicion is needed for earlier diagnosis and treatment to improve prognosis.
