Nocardia infection over 5 years (2011-2015) in an Italian tertiary care hospital.

This study was conducted reviewing clinical records of 14 patients affected by nocardiosis over 5 years in a tertiary care hospital. Nocardia abscessus was responsible for one third of infections, deviating significantly from the results reported by other epidemiological investigations and highlighting the key role of molecular identification tests. Indeed, a precise identification of species is crucial for the determination of antibiotic sensitivity patterns and, consequently, for the choice of antibiotic treatment.

Disseminated Mycobacterium chimaera infection after open heart surgery in an Italian woman: a case report and a review of the literature.

We report the first Italian case of Mycobacterium chimaera disseminated infection in a patient with a history of cardiac surgery. The patient was initially diagnosed with sarcoidosis and started on immunosuppressive therapy. Ten months later she developed a vertebral osteomyelitis: M.

Successful Antifungal Combination Therapy and Surgical Approach for Aspergillus fumigatus Suppurative Thyroiditis Associated with Thyrotoxicosis and Review of Published Reports.

In immunocompromised patients, Aspergillus infections are important causes of morbidity and mortality. We describe a patient with cryoglobulinemic vasculitis who developed disseminated invasive aspergillosis with thyrotoxicosis caused by Aspergillus fumigatus. The diagnosis was based upon radiological, microbiological and pathological findings.

[Thalamo-mesencephalic aspergillus abscess in a heart transplant subject: a case report and literature review].

Cerebral aspergillosis is a rare and highly fatal infection that mainly affects immunocompromised patients. We report on a case of a heart transplanted Caucasian man, who arrived at our hospital because of the onset of diplopy. We performed a broad diagnostic work-up: the brain MRI showed a single ring-enhancing thalamo-mesencephalic area suggestive of abscess lesion; cerebrospinal fluid (CSF) analysis disclosed galactomannan and beta-D-glucan antigens.

Aerosolized amphotericin B lipid complex and invasive pulmonary aspergillosis: a case report.

Invasive pulmonary aspergillosis (IPA) is an emerging life-threatening infection in immuno-compromised patients. The incidence of IPA following kidney transplantation is low (between 0.7 and 4%), yet mortality remains unacceptably high (75-80%).

Treatment of chronic pulmonary aspergillosis with voriconazole: review of a case series.

Purpose: Chronic pulmonary aspergillosis (CPA) is a rare disease that primarily affects subjects with moderate immunodepression and/or structural alterations in the lung.

Methods: Data for patients with probable CPA were collected over 24 months. Patients with probable CPA received oral voriconazole, and clinical, laboratory and radiological follow-up was performed at 3, 6 and 12 months.

[Pulmonary tuberculosis mimicking a severe community-acquired pneumonia with rhabdomyolysis].

We relate the case of a 17 year old girl with active pulmonary tuberculosis which mimicked a severe community-acquired pneumonia (CAP) associated to rhabdomyolysis. This report underlines the importance of excluding the diagnosis of pulmonary tuberculosis in any case of CAP which does not respond to standard antibiotic therapy, remembering that the empiric use of fluoroquinolones could delay the initiation of anti-tuberculosis treatment. This is, to our knowledge, the first description of a case of pulmonary tuberculosis complicated with rhabdomyolysis in a young girl without comorbidities.

Lymphocyte subpopulations in active tuberculosis: association with disease severity and the QFT-GIT assay.

Cell-mediated immune response plays an essential role in the pathogenesis of tuberculosis (TB). We retrospectively evaluated lymphocyte subpopulations in 177 active TB patients compared to 93 healthy controls, finding a relevant decrease in total lymphocytes and CD8+ cells. Conversely, activated human leukocyte antigen (HLA-DR+) and CD4+CD57+ cells were higher in the TB group.

[Diagnostic sensitivity of QuantiFERON-TB Gold In-Tube and tuberculin skin test in active tuberculosis: influence of immunocompromission and radiological extent of disease].

Tuberculosis (TB) is a pathology whose control is still unsatisfactory at global level. Traditional diagnostic techniques for active TB diagnosis are inadequate: the diagnostic gold standard is the cultural exam which suffers from lengthy processing and requires highly specialized laboratories. This study analyzed the diagnostic sensitivity of the tuberculin skin test (TST) and QuantiFERON-TB Gold In-Tube (QFT-IT) in 135 active, microbiologically confirmed TB cases.

Prolonged hospitalisation for immigrants and high risk patients with positive smear pulmonary tuberculosis.

Background And Objective: Tuberculosis (TB) occurring in immigrants and resistance to drugs are major problems for TB control in Western countries. Directly observed therapy (DOT) reduces disease transmission, but this approach may have poor results among illegal immigrants. Our aim was to evaluate a prolonged hospitalisation programme to improve early outcome of TB treatment in high risk patients.

[Herpes zoster in general medicine: experience of the Italian group Netaudit].

Herpes zoster is caused by the reactivation of the varicella-zoster virus (VZV) and usually appears many years after primary infection (varicella), induced by immunosuppression due to underlying diseases. Few epidemiological data in Italy are available concerning Herpes zoster, mainly because disease notification is not mandatory. An observational perspective trial was conducted for 12 months by 41 Italian general practitioners belonging to the Netaudit network to determine herpes zoster incidence and its correlation to patients' characteristics (age, gender, educational qualification, co-morbidities), the delay from correct diagnosis to the start of treatment and different drug prescription.

Cytofluorimetric evaluation of DNA ploidy in lung cancer: a bronchoscopic study.

The study of the biological characteristics of lung cancer is gaining more and more interest both because of their potential role as prognostic indicators and for therapeutic reasons. The DNA content estimated by flow cytometry in surgical samples of non-small cell lung cancer (NSCLC) has already been demonstrated to be correlated with survival in these patients. From July 1990 to February 1992 we analyzed the DNA distribution of bronchoscopic biopsies from 88 patients with lung cancer (18 small cell lung cancer, SCLC, and 68 NSCLC, two unspecified histology).

Clinical and demographic aspects of extrathoracic tuberculosis: experience of an Italian university hospital.

Objective: The decline of tuberculosis in industrialised countries concerns mainly its pulmonary forms. We have analysed all the cases of non-respiratory tuberculosis admitted to our hospital between January 2000 and June 2002, and compared epidemiological, clinical and diagnostic features in our area with those observed in other industrialised countries with high immigration rates.

Design: Patients' records were retrospectively analysed for demographic, clinical, laboratory and instrumental data.

Invasive pulmonary aspergillosis after renal transplantation treated by surgery.

Invasive pulmonary aspergillosis is a serious complication in immunocompromised patients. In those unresponsive to pharmacological treatment, or when drug toxicity is excessive, surgery may resolve the condition. A 48-year-old woman with invasive pulmonary aspergillosis after renal transplantation underwent resection of the right upper lobe and the apical segment of the inferior lobe, followed by complete recovery.

Failure of prophylaxis against PCP in patients with HIV infection.

Since the end of the 1980s, primary anti-Pneumocystis carinii pneumonia (PCP) prophylaxis has become a fundamental part of the global AIDS control strategy in industrialized countries. The widespread adoption of anti-PCP chemoprophylaxis has been a key element in prolonging the survival of patients with AIDS. There is general agreement on the need to begin chemoprophylaxis when individual CD4+ cell counts drop below the value of 200/microL.

Concentrations of single-dose meropenem (1 g iv) in bronchoalveolar lavage and epithelial lining fluid.

The concentrations of meropenem were measured in plasma, bronchoalveolar lavage (BAL) and epithelial lining fluid (ELF) 0.5-8 h after the administration of a single 1 g iv dose of meropenem. Thirty-five patients undergoing bronchoscopy were studied.

CD4(+) T cell clones producing both interferon-gamma and interleukin-10 predominate in bronchoalveolar lavages of active pulmonary tuberculosis patients.

The pattern of cytokine production in T cell clones derived from bronchoalveolar lavages (BAL) of active pulmonary tuberculosis (TB) patients was analyzed in clones obtained by limiting dilution procedures which expand with high efficiency either total T lymphocytes, independently of their antigen-recognition specificity, or Mycobacterium tuberculosis-specific T cells. BAL-derived clones, representative of CD4(+) cells from five patients with active TB, produced significantly higher amounts of IFN-gamma than BAL-derived CD4(+) clones from three inactive TB donors or four controls (with unrelated, noninfectious pathology). Average IL-4 and IL-10 production did not differ significantly in the three groups.

Fatal primary multidrug-resistant tuberculosis in a heart transplant recipient.

The incidence of tuberculosis (TB) worldwide is currently on the rise, not only in the general population but also quite notably among immunosuppressed patients. Its incidence among patients undergoing antirejection therapy is considerably higher than in the general population, and heart transplant recipients have been found to carry the highest risk of TB. There are no reported data, however, on primary TB caused by multidrug-resistant (MDR) Mycobacterium tuberculosis (M.
