BACKGROUND Nocardiosis primarily occurs in the setting of immunocompromising conditions. However, it may also occur in immunocompetent patients. We described computed tomography features of pulmonary nocardiosis and compared immunocompetent and immunocompromised patients. MATERIAL/METHODS CT images of 25 patients (Mean age of 39.5 years; 76% male) with pulmonary nocardiosis proved by bronchoa...

Rhodotorula spp. are common saprophytes but may be responsible for systemic infections in immunocompromised patients. Meningitis caused by Rhodotorula spp. in human immunodeficiency virus (HIV) infected patients has been reported only rarely. We present a case of meningitis caused by Rhodotorula rubra in HIV infected patient. The presumptive diagnosis of cryptococcal meningitis was made on the ...

BACKGROUND Cryptococcal infections have been mostly associated with immunocompromised individuals, 80-90% of whom have been HIV-positive patients. Increasingly, cryptococcal infections are being reported in cirrhotic patients who are HIV-negative. The underlying immunologic defects in cirrhotic patients seem to play an important role in predisposing them to cryptococcosis and affecting their mo...

An infant infected with HIV presented with fever, tachypnoea, hypoxia, and radiological evidence of bilateral pneumonitis. Fluorescent antibody technique identified Pneumocystis carinii within 24 hours from secretions obtained by nasopharyngeal aspiration. This rapid, non-invasive method should be the first line investigation of suspected P carinii pneumonia in immunocompromised patients.

Immune reconstitution inflammatory syndrome (IRIS) presents as an exaggerated immune reaction that occurs during dysregulated restoration in immunocompromised patients late-stage human immunodeficiency virus (HIV) infection who have commenced antiretroviral treatments (ART). Virtually any opportunistic pathogen can provoke this type of disorder. In review, we focus on recent developments the id...

Pneumocystis carinii pneumonia (PCP) is a life-threatening opportunistic infection that occurs in immunocompromised hosts, especially patients with the acquired immunodeficiency syndrome (AIDS). However, this infection is increasing in frequency in other immunosuppressed patients, including organ transplant recipients and those with malignancy who are treated with chemotherapeutic regimens. It ...

BACKGROUND Pneumocystis jirovecii pneumonia (PCP) is a frequent opportunistic infection in immunocompromised patients. In literature, presentation and outcome of PCP differs between patients with human immunodeficiency virus (HIV) infection and renal transplant recipients (RTRs). METHODS We conducted a cross-sectional study of patients with PCP based on the HIV and renal transplant registries...

Nontuberculous mycobacteria infrequently cause disseminated infections in immunocompetent hosts. However, they are increasingly being recognized in immunocompromised patients. We present the case of a 40-year-old HIV-positive male presenting with lymphadenopathies and pancytopenia in whom disseminated infection, with bone marrow involvement by Mycobacterium genavense (M. genavense) was diagnosed.

24 Severely immunocompromised HIV-patients can develop various opportunistic infections due to bacteria, 25 viruses, fungi, or protozoa. Here, we report the first isolation of a flagellated protozoan genetically closely 26 related to Herpetomonas samuelpessoai, which is usually a parasite of insects, from the blood of a HIV27 infected patient. 28
