RESUMO

The purpose of this study was to evaluate the impact of surgical timing on survival in patients with left-sided infective endocarditis (IE). This was a retrospective study including 313 patients with left-sided IE between 2009 and 2017. Surgery was defined as urgent (US) or early (ES) if performed within 7 or 28 days, respectively. A multivariable Cox regression analysis including US and ES as time-dependent variables was performed to assess the impact on 1-year mortality. ES was associated with a better survival (aHR 0.349, 95% CI 0.135-0.902), as US (aHR 0.262, 95% CI 0.075-0.915). ES and US were associated with a better prognosis in patients with left-sided IE.

RESUMO

ABSTRACT Diagnosis of schistosomiasis in migrants coming from endemic areas can be difficult, especially in asymptomatic subjects. Light-intensity disease, in fact, may be missed due to the low sensitivity of the stool microscopy and serologic testing cannot distinguish between a resolved infection and an active infection in patients who have been infected and treated in the past, because specific antibodies can persist despite cure. We describe a cross-sectional study conducted on 82 migrants tested for Schistosoma mansoni on single blood (anti-schistosome antibodies, total IgE) and urine [point-of-care (POC) circulating-cathodic-antigen (CCA) test] samples. A positive POC-CCA test (active infection) resulted in two untreated patients with a positive serology while all patients (n = 66) with a past infection showed a negative POC-CCA test. POC-CCA urine test in combination with serology may be helpful in rapidly differentiate active from past S. mansoni infection in migrants coming from endemic areas.

RESUMO

INTRODUCTION: During HIV-1 infection the B-cell compartment undergoes profound changes towards terminal differentiation, which are only partially restored by antiretroviral therapy (cART). MATERIALS AND METHODS: To investigate the impact of infection as early as during primary HIV-1 infection (PHI) we assessed distribution of B-cell subsets in 19 PHI and 25 chronic HIV-1-infected (CHI) individuals before and during 48 weeks of cART as compared to healthy controls (n = 23). We also analysed Immunoglobulin-expression of memory B-cell subsets to identify alterations in Immunoglobulin-maturation. RESULTS: Determination of B-cell subsets at baseline showed that total and Naive B-cells were decreased whereas Activated Memory (AM), Tissue-like Memory (TLM) B-cells and Plasma cells were increased in both PHI and CHI patients. After 4 weeks of cART total B-cells increased, while AM, TLM B-cells and Plasma cells decreased, although without reaching normal levels in either group of individuals. This trend was maintained until week 48, though only total B-cells normalized in both PHI and CHI. Resting Memory (RM) B-cells were preserved since baseline. This subset remained stable in CHI, while was expanded by an early initiation of cART during PHI. Untreated CHI patients showed IgM-overexpression at the expenses of switched (IgM-IgD-) phenotypes of the memory subsets. Interestingly, in PHI patients a significant alteration of Immunoglobulin-expression was evident at BL in TLM cells, and after 4 weeks, despite treatment, in AM and RM subsets. After 48 weeks of therapy, Immunoglobulin-expression of AM and RM almost normalized, but remained perturbed in TLM cells in both groups. CONCLUSIONS: In conclusion, aberrant activated and exhausted B-cell phenotypes rose already during PHI, while most of the alterations in Ig-expression seen in CHI appeared later, despite 4 weeks of effective cART. After 48 weeks of cART B-cell subsets distribution improved although without full normalization, while Immunoglobulin-expression normalized among AM and RM, remaining perturbed in TLM B-cells of PHI and CHI.

RESUMO

Aim of this study was to report the 204-week efficacy and safety results of a novel PI- and NRTI-sparing regimen for salvage therapy including maraviroc, raltegravir, etravirine in 28 failing HIV-infected patients with R5-tropic virus. The trend of laboratory parameters was tested by ANOVA for repeated measures and Greenhouse-Geisser probabilities were reported. Results were described as median (Q1-Q3) values. Twenty-six (93%) out of 28 patients completed 204 weeks of treatment. Virological success (HIV-RNA<50 copies/mL) at week 204 was 96%. CD4+ counts significantly increased [244 (158-213) cells/mm3, p<0.0001] from baseline [247 (68-355) cells/mm(3)] as well as CD4+ percentage. Four serious adverse events (1 death due to Hodgkins's lymphoma, 1 anal cancer, 1 Hodgkins's lymphoma, 1 recurrence of mycobacterial spondylodiscitis) were observed; three events led to transitory discontinuation of the antiretroviral therapy due to drug-drug interaction. BMI (p<0.0001) and waist circumference (p<0.0001) significantly increased over 204 weeks. An amelioration was also observed in relation to haemoglobin (p=0.0006), platelets (p<0.0001), white blood cell (p=0.013), neutrophils (p=0.301), lymphocytes (p=0.207) and creatinine (p<0.0001). In highly treatment-experienced patients the maraviroc, raltegravir and etravirine combination is associated with a good long-term efficacy and safety profile.
