Rare Multidrug-Resistant Pulmonary Nocardiosis in AIDS
نویسندگان
چکیده
Nocardiosis is an opportunistic infection in patients with depressed cell-mediated immunity. Inhalation is the primary route for exposure via dust particles. Patients with acquired immune deficiency syndrome (AIDS) are at increased risk of disseminated disease. A challenge in the diagnosis of pulmonary nocardiosis is that it can mimic other pulmonary diseases. Nocardia farcinica tends to be a more virulent, multidrug-resistant strain with an increased tendency to disseminate. This report describes a 64-year-old man with AIDS found to have pulmonary nocardiosis that did not respond to standard antibiotic therapy. Further evaluation revealed the virulent, multidrug-resistant Nocardia farcinica species. Targeted antibiotic therapy was initiated, after which the patient had an improvement in pulmonary symptoms. It is important to suspect pulmonary nocardiosis in immunocompromised patients who fail to respond to standard antimicrobial therapy. Susceptibilities should be obtained so that appropriate therapy can be promptly initiated as Nocardia farcinica is highly resistant to multiple antimicrobials.

Pemphigus is a chronic blistering mucocutaneous disease, classified in immunobullous skin diseases. Infections, particularly septicemia due to Staphylococcus aureus and Pseudomonas aeroginosa are the most common and dangerous disorders due to immunosuppressive therapy in this disease. Infection with nocardia is rare, so that only 6 cases have been reported yet. Herein, we report a 56-year-old m...

Idiopathic CD4 T-lymphocytopenia (ICL) is a rare immunodeficiency characterized by low CD4 T-lymphocyte count, which usually manifests with opportunistic infections. Nocardia as an opportunistic pathogen infecting patients with this condition has rarely been reported. Here, we describe the case of a 46-year-old male who presented with lung mass and respiratory and systemic symptoms and was even...

INTRODUCTION Nocardia species usually cause opportunistic infections, and the frequency of these infections is increasing owing to the growing population of immunocompromised hosts. However, Nocardia species may sometimes cause an infection disease in immunocompetent hosts. Nocardia mexicana infections are the least common and are very rare. CASE PRESENTATION Herein, we report the first case ...
متن کاملThe radiographic appearance of pulmonary nocardiosis associated with AIDS.
Pulmonary nocardiosis is a well-described infection in immunocompromised patients; however, it is less well documented in patients with AIDS. The pulmonary manifestation in 21 HIV-positive patients who developed pulmonary infection with Nocardia asteroides is described. The radiographic picture included lobar or multilobar consolidation (52 percent [11/21]), solitary masses (24 percent [5/21]),...
