The relationship between mental fatigue, cognitive functioning, and employment status in patients with low-grade glioma: a cross-sectional single-center study.

PURPOSE: To evaluate fatigue and cognitive functioning in patients with low-grade glioma and to assess whether cognitive functioning and employment status differ between patients with severe and non-severe mental fatigue. METHODS: Cross-sectional study. Fatigue was measured with the multidimensional fatigue inventory, objective cognitive functioning with a neuropsychological test battery, and mood with the Center for Epidemiological Studies Depression Scale. RESULTS: Thirty-one patients, mean age 44 ± 11, mean time post-diagnosis 2.5 ± 1.4 years, participated. Severe mental fatigue was present in 55% and depression in 36% of the patients. Attention deficits were observed in 75% (Stroop's test), memory deficits in 36% (Rey Auditory Verbal Learning Test), and executive functioning deficits in 42% (Stroop's test). Severe mental fatigue patients demonstrated significantly worse scores on Stroop's test-Card-II (p = 0.043), Trail Making Test-B (p = 0.014), Trail Making Test-B/A (p = 0.014), and Digit-Span (p = 0.046), compared to non-severe mental fatigue patients. Severe mental fatigue patients worked significantly less hours per week (p = 0.013) and had more changes in their employment status (p = 0.009) after diagnosis. CONCLUSIONS: Patients with low grade glioma show high rates of fatigue, especially in the mental domain, which might be associated with deficits in cognitive functioning and changes in employment status.Implications for rehabilitationThe majority of patients with low grade glioma suffers from severe mental fatigue and has deficits in cognitive functioning, which may affect employment status.Patients with low grade glioma should be screened for fatigue with the multidimensional fatigue inventory, to differentiate between mental and physical fatigue.Patients with low grade glioma with severe mental fatigue should be screened for problems in cognitive functioning with an objective neuropsychological test battery.Cognitive and vocational rehabilitation programs should aim at coping with severe mental fatigue and attention deficits in patients with low grade glioma.

The diabetes-tuberculosis co-epidemic: the role of international migration.

SETTING: A tuberculosis (TB) referral centre in Rome, Italy. OBJECTIVE: To identify demographic and epidemiological characteristics associated with diabetes mellitus (DM) among patients with TB and to compare the clinical presentation of TB and TB-DM in the light of the growing worldwide burden of DM. DESIGN: We performed a retrospective study of TB cases diagnosed from 2007 to 2012. RESULTS: Among 971 TB patients, 723 were foreign-born and 63 (6.5%) had DM. DM prevalence was 12.7% (8/63) among those born in countries with DM prevalence ⩾8%, 4.7% (31/660) among patients from countries with DM prevalence <8% and 9.7% among Italian patients (24/248). In multivariable analysis, DM was independently associated with older age, and with being born in countries other than Italy, compared to Italians; this latter association was stronger in older patients. DM patients were also significantly more likely to be male and less likely to test positive for the human immunodeficiency virus. The presence of cavities was significantly associated with DM. CONCLUSIONS: As individuals born in high TB incidence and high DM prevalence countries emerge as a vulnerable population, greater attention to bidirectional low-cost screening in people from these countries is needed.

Severe EBV hepatitis treated with valganciclovir.

We describe the case of an 18-year-old immunocompetent male patient with severe hepatitis during primary Epstein-Barr virus infection, treated with oral valganciclovir. During the initial therapy with corticosteroids, the patient's clinical condition and liver function worsened, so we decided to add oral valganciclovir for its good bio-availability and previous encouraging experiences in different clinical settings, with rapid resolution of the symptoms.

Pulmonary tuberculosis in HIV-infected patients presenting with normal chest radiograph and negative sputum smear.

BACKGROUND: HIV-infected patients with pulmonary tuberculosis exhibit atypical radiological presentation and negative sputum smear more frequently than their HIV-negative counterparts. PATIENTS AND METHODS: We performed a retrospective study based on a chart review of 146 HIV-infected patients with pulmonary symptoms and culture-proven pulmonary tuberculosis. We compared clinical characteristics and the outcome in 71 patients (49%) with positive sputum smear (SS+), 62 patients (42%) with negative sputum smear/abnormal chest X-ray (SS-/CXR+) and 13 patients (9%) with negative sputum smear/normal chest X-ray (SS-/CXR-). Patients were enrolled from January 1987 to December 1998, and were followed up until December 1999. RESULTS: On hospital admission the three groups of patients examined did not differ significantly in demographic characteristics, degree of immunosuppression or Mycobacterium tuberculosis drug-susceptibility pattern. SS-/CXR- patients were significantly Less LikeLy to present with prolonged fever and dyspnea. Median survival was shorter for SS-/CXR- patients (6.4 months vs 20.2 and 18.8 months in the other two groups). In multivariate analysis, SS-/CXR-patients had a significantly increased risk of death (hazard ratio 3.0, 95% confidence interval, 1.4 to 6.4, p = 0.004) compared to SS+ patients. This increase in risk was no longer statistically significant when initiation of antituberculous therapy within 8 weeks from the collection date of the first specimen yielding M. tuberculosis was included in the multivariate model. CONCLUSION: Decreased survival was observed in HIV-infected patients with pulmonary tuberculosis and with both negative sputum smear and normaL chest X-ray presentation. This may primarily be a resuLt of delayed tuberculosis diagnosis and initiation of antituberculous therapy. The latter delay may also lead to a faster progression of HIV infection in SS-/CXR patients, in whom diagnostic oversight may be common.

Primary pulmonary hypertension in HIV patients: a systematic review.

The relationship between grade of pulmonary hypertension and factors associated with human immunodeficiency virus among patients with HIV infection is poorly documented. This report documents the most extensive attempt made thus far to determine whether a relationship exists between degree of pulmonary hypertension and the following conditions: HIV risk factor, degree of immunosuppression, presence or absence of AIDS, and presence or absence of liver cirrhosis. A retrospective study involving a search of the published literature on primary pulmonary hypertension among HIV cases from 1987 to 1998, using the Medline and Aidsline databases was conducted. Patients for whom secondary causes of pulmonary hypertension could be excluded were selected, and the following information for each was recorded: age, gender, risk factors for HIV infection, HIV disease stage according to the Centers for Disease Control, previous opportunistic and neoplastic diseases, CD4+ cell count (cells/L), presence or absence of liver cirrhosis, pulmonary systolic artery pressure level, and lung pathology specimens. Information about the patient's survival time was also recorded. Seventy-six patients were judged to have primary pulmonary hypertension and were included in the study. While no correlation was found between pulmonary systolic artery pressure level and CD4+ cell counts, a statistically significant difference was found between HIV-positive patients with and without AIDS as determined by the Centers for Disease Control criteria with regard to the degree of pulmonary hypertension, expressed as pulmonary systolic artery pressure level (85.4 +/- 17 mm Hg vs 71.8 +/- 15 mm Hg, p < 0.013). Although a higher PAPS was present in HIV cirrhotic patients, a statistically significant difference was not found between degree of pulmonary hypertension and evidence of hepatic cirrhosis (85 +/- 21 mm Hg vs 73.1 +/- 15 mm Hg, p < 0.062). Patients with AIDS and primary pulmonary hypertension present a higher degree of pulmonary hypertension than non-AIDS patients. Pulmonary hypertension associated with HIV seems to be related to a cytokine-related stimulation and proliferation of endothelium. High levels of cytokines present in AIDS patients can favor pulmonary hypertension, but the role of a host response to HIV--determined by one or more HLA subtypes--is suspected to enhance high cytokine production levels.

[Mycobacterium tuberculosis drug resistance in patients with HIV and pulmonary tuberculosis infections in Rome: 1987-1996]. / La farmaco-resistenza di Mycobacterium tuberculosis nei pazienti con infezione da HIV e tubercolosi polmonare in Roma: 1987-1996.

A retrospective chart review was performed on 118 HIV infected patients with pulmonary tuberculosis hospitalized between 1987 and 1996 in a tertiary care center for Infectious Diseases in Rome. The aims of this study were: a) to evaluate global prevalence of and risk factors for drug-resistant Mycobacterium tuberculosis and multidrug resistant tuberculosis; b) to assess trends in prevalence of drug-resistant tuberculosis over the 10-year study period. Prevalence of drug resistance of first Mycobacterium tuberculosis isolates was tested on Lowenstein-Jensen medium with the proportional method. Of the 118 patients studied, 83 had never been treated for tuberculosis and 35 had already been treated for at least 1 month. The overall prevalence of resistance to one or more drugs was 25% (17% in never treated patients vs 46% in already treated patients; p = 0.002). Five percent of isolates were resistant to both isoniazid and rifampin (1% in never treated patients vs 14% in already treated patients; p = 0.008). Resistance rates to individual drugs were: isoniazid 14%, rifampin 8%, ethambutol 0%, streptomycin 13%. During the study period no significant variations in prevalence of drug-resistant tuberculosis were found. In our area, empiric therapy should include 4 drugs: as well as isoniazid, rifampin and pyrazinamide, we recommend ethambutol. Surveillance of drug-resistant tuberculosis is needed. Directly observed therapy should be considered for HIV patients in order to prevent increases in drug resistance, relapses, and treatment failures.

Role of human immunodeficiency virus in primary pulmonary hypertension--case reports.

Previous cases of pulmonary hypertension (PH) in human immunodeficiency virus (HIV) infection have been reported in the literature. The role of HIV in PH is still debatable. The purpose of this report was to analyze whether HIV plays a direct or indirect role in PH pathogenesis. Between February and November 1997, 56 HIV-infected patients with cardiac symptoms and signs were studied by serial color Doppler echocardiography. In four patients (7.1%), PH not related to other well-known associated conditions, was disclosed. In spite of a low serum HIV RNA viral load and a high-efficacy antiretroviral therapy, including a protease inhibitor in two patients, PH developed and worsened. It could be hypothesized that in some patients with an individual immunogenetic predisposition, a high secretion of cytokines and endothelin-1 stimulated by an unidentified pathogen different from HIV could lead to PH. Antiretroviral therapy seems not to prevent or reduce right ventricle pressure gradient in PH.
