Polymorphisms within the TNFSF4 and mapkapk2 loci influence the risk of developing invasive aspergillosis: A two-stage case control study in the cont…
2020
Here, we assessed whether 36 single nucleotide polymorphisms (SNPs) within the TNFSF4 and MAPKAPK2 loci influence the risk of developing invasive aspergillosis (IA). We conducted a twostage case control study including 911 high-risk patients diagnosed with hematological malignancies that were ascertained through the aspBIOmics consortium. The meta-analysis of the discovery and replication populations revealed that carriers of the TNFSF4rs7526628T/T genotype had a significantly increased risk of developing IA (p = 0.00022). We also found that carriers of the TNFSF4rs7526628T allele showed decreased serum levels of TNFSF14 protein (p = 0.0027), and that their macrophages had a decreased fungi…
First case of Mediterranean spotted fever-associated rhabdomyolysis leading to fatal acute renal failure and encephalitis
2014
SummaryMediterranean spotted fever (MSF) is a tick-borne zoonosis caused by Rickettsia conorii. In Italy, about 400 cases are reported every year and nearly half of them occur in Sicily, which is one of the most endemic regions. Although MSF is mostly a self-limited disease characterized by fever, skin rash, and a dark eschar at the site of the tick bite called a ‘tache noire’, serious complications are described, mainly in adult patients. Nevertheless, severe forms of the disease with major morbidity and a higher mortality risk have been described. We report a fatal case of MSF complicated by rhabdomyolysis, acute renal failure, and encephalitis in an elderly woman.
Diagnostic and vaccine strategies to prevent infections in patients with inflammatory bowel disease.
2016
Summary Objectives The treatment of inflammatory bowel disease (IBD) has been revolutionized by the use of immunomodulatory agents. Although these potent drugs are effective in controlling disease activity, they also cause an increased risk of new infections or reactivation of latent infections. On these premises, we aimed to provide guidance on the definitions of immunocompromised patients, opportunistic infections and the risk factors associated with their occurrence in an IBD context, and to suggest the proper screening tests for infectious diseases and the vaccination schedules to perform before and/or during therapy with immunomodulators. Methods All the most recent evidences – filtere…
Microsatellite-based genotyping of Candida parapsilosis sensu stricto isolates reveals dominance and persistence of a particular epidemiological clon…
2012
In this study, using multilocus microsatellite analysis, we report the genetic characterization of 27 Candida parapsilosis isolates recovered in two different periods of time (2007-2009 and 2011-2012) from infants hospitalized in the neonatal intensive care unit of a hospital in Messina, Italy. The results revealed the persistence and dominance of a particular infectious genotype among NICU patients and highlight the power of the used microsatellite markers in clarifying epidemiologic associations, detect micro-evolutionary variations and facilitating the recognition of outbreaks. © 2012 Elsevier B.V.
The socio-ecology of zoonotic infections
2011
The resurgence of infectious diseases of zoonotic origin observed in recent years imposes a major morbidity/mortality burden worldwide, and also a major economic burden that extends beyond pure medical costs. The resurgence and epidemiology of zoonoses are complex and dynamic, being influenced by varying parameters that can roughly be categorized as human-related, pathogen-related, and climate/environment-related; however, there is significant interplay between these factors. Human-related factors include modern life trends such as ecotourism, increased exposure through hunting or pet owning, and culinary habits, industrialization sequelae such as farming/food chain intensification, globali…
Current and future challenges in HCV: insights from an Italian experts panel
2017
Background: The recent availability of direct acting antiviral drugs (DAAs) has drastically changed hepatitis C virus (HCV) treatment scenarios, due to the exceedingly high rates of sustained virological response (SVR) and excellent tolerability allowing for treatment at all disease stages. Methods: A panel of Italian experts was convened twice, in November 2016 and January 2017, to provide further support on some open issues and provide guidance for personalized HCV care, also in light of forthcoming regimens. Results and conclusions: Treatment recommendations issued by international and national liver societies to guide clinicians in the management of HCV infection are constantly updated …
Body Mass Index and Weight Gain in Pregnant Women With HIV: A National Study in Italy.
2013
Although most of the women (69.4%) had a normal BMI at start of pregnancy, only 37% had an adequate weight gain during pregnancy. Inadequate body weight gain was more common (44.8%) than excessive weight gain (18.2%), but 40% of overweight women and 50% of obese women had an excessive weight gain in pregnancy, with about 9% of the women in these categories gaining >18 kg during pregnancy (Table 1). Only 1.9% of the women had a vaginal delivery; elective and nonelective cesarean deliveries accounted for 81.3% and 16.7% of deliveries, respectively. Compared to underweight/normal women, overweight/obese women had similar occurrences of preterm delivery (23.4% vs 22.7%, P = .871), significantly…
Visceral leishmaniasis, hypertriglyceridemia and secondary hemophagocytic lymphohistiocytosis
2016
cytokines, an upregulation of adhesion molecules and MHC I and II molecules on mono/macrophages, and an expansion of inflammatory monocytes. This exaggerated inflammatory response is responsible for necrosis and organ failure and results in uncontrolled proliferation and phagocytic activity of histiocytes [2]. Hypertriglyceridemia (fasting, greater than or equal to 265 mg/100 ml) is one of the current diagnostic criteria for HLH [2]. Several studies link hypertriglyceridemia to inhibition of lipoprotein lipase (LPL) by tumor necrosis factor-α (TNF-α), and TNF-α is a powerful autocrine and paracrine regulator of adipose tissue [3]. Indeed, many different sources of intense and prolonged T-ly…
TEM morphological characterization of a one-step self-etching system applied clinically to human caries-affected dentin and deep sound dentin
2013
Purpose: To examine morphologically the hybrid layer of one-step self-etching adhesive, Clearfil S3 Bond (S3bond), in caries-affected dentin (CAD) and deep sound dentin (DSD) cavities performed clinically. For a comparative group, the two-step self etching adhesive Clearfil Protect Bond (Pbond) was used in a similar clinical situation. Methods: This study was carried out on carious and sound teeth clinically selected for extraction. In carious teeth, CAD was obtained by way of subjective criteria by removing infected tissue to form a cavity bottom. DSD was obtained at a depth of 4 mm in the dentin cavity of sound teeth. S3bond and Pbond were applied in the CAD and DSD cavities as indicated …
Traditional endodontic surgery versus modern technique: a 5-year controlled clinical trial.
2014
In this study, we compared outcomes of traditional apicoectomy versus modern apicoectomy, by means of a controlled clinical trial with a 5-year follow-up. The study investigated 938 teeth in 843 patients. On the basis of the procedure performed, the teeth were grouped in 3 groups. Differences between the groups were the method of osteotomy (type of instruments used), type of preparation of retrograde cavity (different apicoectomy angles and instruments used for root-end preparation), and root-end filling material used (gray mineral trioxide aggregate or silver amalgam). Outcome (tooth healing) was estimated after 1 and 5 years, postoperatively. Clinical success rates after 1 year were 67% (…
