Infections by Listeria monocytogenes typically occur in infants, the elderly, pregnant women, and immunosuppressed subjects. Pulmonary infections in adults are extremely uncommon and only few reports can be found in the literature. We here report a case of Listeria pneumonia in an 85-year-old female patient and we discuss our diagnostic and therapeutic approach. Despite being rare and in most c...

HPV: Human papillomavirus INTRODUCTION Common cutaneous warts caused by human papillomavirus (HPV) strains 1, 2, and 4, can be challenging to treat. Immunosuppressed patients are especially vulnerable to this infection, and the warts may cause physical and psychologic distress. There are currently 3 commercially available vaccines in the United States that target HPV strains commonly associated...

In the first study, we tested the ability of a commercial feed additive (OmniGen-AF) to affect markers of innate immunity in immunosuppressed sheep and the ability of a pathogen challenge (mould) to affect the immune response to the additive. Treatments consisted of (1) control, (2) immunosuppressed with dexamethasone (DEX), (3) immunosuppressed plus the feed additive, (4) immunosuppressed plus...

BACKGROUND Immunosuppressed patients are at risk of severe viral infections-related complications. National and international vaccination guidelines have been developed to decrease the mortality risk associated with these infections. However, a summary of these guidelines and the value of immunisation in this population is missing. OBJECTIVES To summarize specific guidelines regarding vaccina...

An immunologically immunosuppressed mouse model of Pneumocystis carinii pneumonia using antibody developed by Dialynas et al. (Immunol. Rev. 74:29-55, 1983) directed to L3T4+ T cells (referred to as L3T4+ antibody) was compared with a corticosteroid-immunosuppressed mouse model. Corticosteroid- or L3T4+ antibody-immunosuppressed BALB/c mice transtracheally inoculated with P. carinii developed s...

The main purpose of cleanrooms in health care centres is to prevent hospital infections or leakage of a highly infectious agent (the source of haemorrhagic fevers, SARS, etc.) into the ambient environment and subsequently possibly threatening other individuals. Patients with haematological malignancies or after autologous or allogeneic haematopoietic stem cell transplantation (HSCT) rank among ...

To determine if cases of invasive aspergillosis (IA) were caused by strains of Aspergillus fumigatus with unique characteristics, strains from immunosuppressed patients with IA were compared to strains obtained from sputa of patients with cystic fibrosis and to strains from the environment. An extremely high genomic diversity was observed among the 879 strains typed by Southern blotting with a ...

BACKGROUND Rhodococcus species are relatively rare human pathogens, but are being increasingly recognized as causes of infection especially in immunosuppressed patients. CASE REPORT We present a case of Rhodococcus lung abscess in a patient 10 months post-cadaveric renal transplant, successfully treated with a combination of antibiotics. She required a prolonged course of oral antibiotics for...

Using a recently developed chromogenic substrate assay sensitive to 10 pg/ml Escherichia coli endotoxin in plasma, systemic endotoxaemia was found in 52% of 21 episodes of fever in patients with a haematological malignancy who were infected. Endotoxaemia was also found in 27% of 22 episodes of fever of unknown origin. In 45 afebrile patients neither neutropenia nor cytotoxic chemotherapy was a ...
