Migrations do not modify Mycobacterium tuberculosis resistance rates: a 20-year retrospective study.

Tuberculosis (TB) caused by resistant strains is becoming a public health concern also in high-income countries. In Pavia province, Northern Italy, the prevalence of foreign-born has increased in recent years. Nevertheless, it is unclear if this has modified epidemiology and resistance patterns of Mycobacterium tuberculosis. We retrospectively collected data on all the Mycobacterium tuberculosis strains isolated by culture in the microbiology reference laboratory of the province of Pavia from 01/01/1998 to 31/12/2017. Overall, 919 patients were identified, 320 were foreign-born (34.8%). The proportion of cases due to foreign-born patients increased during the study period as did resistance to isoniazid (INH) (p = 0.01), while resistance to rifampicin (RIF) did not (p = 0.8). INH and RIF resistance were comparable among Italian and foreign-born patients (7.9% vs 9.7% for INH and 4% vs 5% for RIF, respectively). Twenty-height (3.05%) patients harboured MDR strains. Prevalence of MDR strains was not different between Italians and foreign-born patients (2.8% vs 3.4%, p = 0.6). During the study period the proportion of TB cases due to foreign-born patients and INH resistance increased. This increase was equal among Italian and foreign-born patients. Migrants in our area are not a driver of resistance to anti-mycobacterial drugs.

Necrotizing Fasciitis by Two Anaerobic Bacteria in an Immunocompetent Patient after Minor Trauma: A Case Report.

Necrotizing fasciitis (NF) is a soft tissue infection affecting subcutaneous tissue and the muscular fascia without involvement of the muscle and can be either monomicrobial or polymicrobial. Monomicrobial infections are usually caused by group A streptococci, while infections caused by anaerobic germs usually affect immunodepressed patients. We report a rare case of NF caused by two anaerobic bacteria in an immunocompetent patient.

Emerging biological agents for hepatitis C.

INTRODUCTION: New direct-acting antiviral agents have changed the landscape of treatment of chronic HCV infection. Despite current treatments are well tolerated with a high rate of sustained virological response (SVR), some medical needs remain. Nowadays there are a large number of approved medications for the treatment of HCV infection; nevertheless, new studies are conducted to find new agents and new combinations. AREAS COVERED: A literature research of new antiviral compounds indicated for the treatment of HCV infection was achieved by an online search of medication undergoing development on Pubmed and clinicalTrials.gov clinical trials registry. We considered phase I/II studies and some randomized Phase III trials. EXPERT OPINION: More knowledge about impact of HCV eradication on disease progression and more confidence regarding drug-drug interaction are needed. Furthermore, each treatment should be individualized targeting the patients needs with the aim not only to obtain viral suppression but also to stop progression of liver disease and HCV related conditions, and to improve patient health status.

N-terminal probrain natriuretic peptide is a stronger predictor of cardiovascular mortality than C-reactive protein and albumin excretion rate in elderly patients with type 2 diabetes: the Casale Monferrato population-based study.

OBJECTIVE: To study whether N-terminal probrain natriuretic peptide (NT-proBNP) is a short-term independent predictor of both all-cause and cardiovascular (CV) mortality in type 2 diabetic patients and to establish whether albuminuria and C-reactive protein (CRP) affect this relationship. RESEARCH DESIGN AND METHODS: The prospective study included 1,825 type 2 diabetic patients from the population-based cohort of the Casale Monferrato study. CV risk factors, preexisting CVD, and NT-proBNP levels were evaluated at baseline. All-cause and CV mortality were assessed 5.5 years after baseline examination. Multivariate Cox proportional hazards modeling was used to estimate mortality hazard ratios (HRs). RESULTS: During the follow-up period, 390 people died (175 for CVD) out of 9,101 person-years of observations. A significantly increased mortality risk by quartiles of NT-proBNP was observed (test for trend, P < 0.001). NT-proBN P values >91 pg/mL conferred HRs of 2.05 (95% CI 1.47-2.86) for all-cause and 4.47 (2.38-8.39) for CV mortality, independently of CV risk factors, including CRP and albumin excretion rate (AER). The association was also significant for modest rises in NT-proBNP levels and in patients without microalbuminuria and CVD at baseline (upper quartiles HRs 3.82 [95% CI 1.24-13.75]) and 3.14 [1.00-9.94]). Albuminuria and NT-proBNP had an additive effect on mortality, though the association was stronger for NT-proBNP. CONCLUSIONS: NT-proBNP is a strong independent predictor of short-term CV mortality risk in elderly people with type 2 diabetes, including those without preexisting CVD. This association is evident even in people with slightly increased values, is not modified by CRP, and is additive to that provided by AER.
