Typhoid Fever

2008

Typhoid fever continues to be a serious public health problem, with approximately 22. million cases and more than 200. 000 deaths globally. The disease is most often acquired by ingestion of food or water contaminated by the feces and less frequently by urine or vomitus of patients and carriers. Prolonged low-grade fever, headache, dry cough, alterations of bowel habits, coated tongue, and rose spots are the typical clinical features. Definitive diagnosis requires the isolation of Salmonella enterica serovar Typhi. Supportive serological tests are also used. First-choice antibiotic treatment includes fluoroquinolones or third-generation cephalosporins and reduces the mortality rate from 20%…

Is physician assessment of alcohol consumption useful in predicting risk of severe liver disease among people with HIV and HIV/HCV co-infection?

2019

AbstractBackgroundAlcohol consumption is a known risk factor for liver disease in HIV-infected populations. Therefore, knowledge of alcohol consumption behaviour and risk of disease progression associated with hazardous drinking are important in the overall management of HIV disease. We aimed at assessing the usefulness of routine data collected on alcohol consumption in predicting risk of severe liver disease (SLD) among people living with HIV (PLWHIV) with or without hepatitis C infection seen for routine clinical care in Italy.MethodsWe included PLWHIV from two observational cohorts in Italy (ICONA and HepaICONA). Alcohol consumption was assessed by physician interview and categorized ac…

Risk for non-AIDS-defining and AIDS-defining cancer of early versus delayed initiation of antiretroviral therapy

2021

BACKGROUND: Immediate initiation of antiretroviral therapy (ART) regardless of CD4 cell count reduces risk for AIDS and non-AIDS-related events in asymptomatic, HIV-positive persons and is the standard of care. However, most HIV-positive persons initiate ART when their CD4 count decreases below 500 × 10 9 cells/L. Consequences of delayed ART on risk for non-AIDS-defining and AIDS-defining cancer, one of the most common reasons for death in HIV, are unclear. OBJECTIVE: To estimate the long-term risk difference for cancer with the immediate ART strategy.DESIGN: Multinational prospective cohort study.SETTING: The D:A:D (Data collection on Adverse events of anti-HIV Drugs) study, which included…

Helicobacter pylori and epstein–barr co-infection in gastric disease

2017

The incidence of gastrointestinal diseases and in particular gastric cancer (GC) is high worldwide. Over the last few years, numerous studies have speculated that Helicobacter pylori (H. pylori) and Epstein-Barr virus (EBV) can be correlated with gastric cancerogenesis. Virulence factors of H. pylori can contribute to the variability of clinical outcomes: among the most important virulence factors is the pathogenicity island (CagPAI), vacA and oipA gene. EBV infection usually persists in B cells and induces an inflammatory reaction in cooperation with H. pylori. In Sicily, H. pylori and EBV infections are particularly prevalent, and to our knowledge no study has addressed this yet. The aim …

Surveillance of enteric virus infections in a neonatal intensive care unit.

2005

Objective. To investigate the epidemiology of neonatal viral gastroenteritis compared to the circulation of enteric viruses in children, 109 newborns in the NICU of Mother and Child Department and 214 children with enteritis admitted to the “G. Di Cristina” Children’s Hospital in Palermo were monitored for Rotavirus, Adenovirus, Astrovirus and Norovirus infections. Methods. Stool samples were examined by EIA to detect viral antigens. Rotavirus strains were subjected to P- and G-typing. Results. A Norovirus strain was detected in one neonatal stool specimen whereas an astrovirus strain was dectected in two neonatal specimens. No Rotavirus or Adenovirus infection was identified among the newb…

VIRULENCE FACTORS AND ANTIMICROBIAL RESISTANCE OF ESCHERICHIA COLI ST131 IN COMMUNITY-ONSET HEALTHCARE-ASSOCIATED INFECTIONS IN SICILY, ITALY

2017

Escherichia coli ST131 is an emerging resistant agent recently called “superbug” in England. This strain is responsible of community-acquired urinary tract infections and nowadays showing increasing resistance to antibiotics like fluoroquinolones and cephalosporins. Survey of virulent bacterial clone is relevant to control its spreading in community. We aim to assess the circulation of resistant clones Escherichia coli ST131 outside of the hospital to prompt control of outbreak in our geographical area. We selected 105 E. coli resistant isolates from community-acquired urinary infections and performed a multiplex PCR to evaluate if they belonged to the ST131 type. We investigated their set …

[Mediterranean spotted fever in paediatric and adult patients: two clinical aspects of the same disease].

2012

Mediterranean Spotted Fever is an acute febrile disease caused by Rickettsia conorii and transmitted to humans by the brown dog tick Rhipicephalus sanguineus. Nearly 400 cases are reported every year in Sicily, mainly from June to September. The aim of this study is to compare the clinical and laboratory features of two different groups of patients , one of adults and one of children. The analysis included all adult patients with MSF diagnosed at the Institute of Infectious Diseases, Paolo Giaccone University Polyclinic in Palermo, during the period January 2007- August 2010 and all the children diagnosed with MSF at the G. Di Cristina Children Hospital in Palermo during the period January …

Effectiveness of dolutegravir-based regimens as either first-line or switch antiretroviral therapy: data from the Icona cohort

2019

Introduction: Concerns about dolutegravir (DTG) tolerability in the real-life setting have recently arisen. We aimed to estimate the risk of treatment discontinuation and virological failure of DTG-based regimens from a large cohort of HIV-infected individuals. Methods: We performed a multicentre, observational study including all antiretroviral therapy (ART)-naïve and virologically suppressed treatment-experienced (TE) patients from the Icona (Italian Cohort Naïve Antiretrovirals) cohort who started, for the first time, a DTG-based regimen from January 2015 to December 2017. We estimated the cumulative risk of DTG discontinuation regardless of the reason and for toxicity, and of virologica…

Switching to dual/monotherapy determines an increase in CD8+ in HIV-infected individuals: An observational cohort study

2018

Background The CD4/CD8 ratio has been associated with the risk of AIDS and non-AIDS events. We describe trends in immunological parameters in people who underwent a switch to monotherapy or dual therapy, compared to a control group remaining on triple antiretroviral therapy (ART). Methods We included patients in Icona who started a three-drug combination ART regimen from an ART-naïve status and achieved a viral load ≤ 50 copies/mL; they were subsequently switched to another triple or to a mono or double regimen. Standard linear regression at fixed points in time (12-24 months after the switch) and linear mixed model analysis with random intercepts and slopes were used to compare CD4 and CD8…

Osteoporosis risk factors in HIV positive women with osteoporosis: A retrospective analysis

2017

Multifactorial risk factors such as HIV/HCV co-infection and antiretroviral therapy (ARV) have been associated with osteoporosis in HIV+ women. We retrospectively analysed which known risk factors were associated with the diagnosis of osteoporosis, according to the WHO definition, in HIV positive women who were followed-up at the AIDS Centre of the University of Palermo, Italy between January 2011 and December 2014. Twenty-one HIV+ women with osteoporosis (13 HIV+ mono-infected and 8 HIV/HCV co-infected females) who underwent dual-energy X-ray absorptiometry (DXA) and liver stiffness assessment were included in the study. No significant differences between the HIV and HIV/HCV group were fou…

Fungal infections in transplantation patients

2003

Invasive fungal infections have became one of the principal obstacles to successful solid organ and bone marrow transplantation. The natural history and incidence of systemic fungal infection varies with the type of organ transplanted and the immunosuppressive therapy administered; the majority of infections occur within the first two months after transplantation. The most common fungi that cause disease in transplant recipients are Candida spp. and Aspergillus spp. The clinical presentations of fungal infections in solid-organ transplant recipients are non specific and often overlap with other infectious and non infectious processes; for this reason it's important maintain a high index of …

Epidemiology and Microbiology of Skin and Soft Tissue Infections: Preliminary Results of a National Registry

2018

Skin and soft tissue infections (SSTIs) represent a wide range of clinical conditions characterized by a considerable variety of clinical presentations and severity. Their aetiology can also vary, with numerous possible causative pathogens. While other authors previously published analyses on several types of SSTI and on restricted types of patients, we conducted a large nationwide surveillance programme on behalf of the Italian Society of Infectious and Tropical Diseases to assess the clinical and microbiological characteristics of the whole SSTI spectrum, from mild to severe life-threatening infections, in both inpatients and outpatients. Twenty-five Infectious Diseases (ID) Centres throu…

A NEW CASE OF LOUSE-BORNE RELAPSING FEVER IN SICILY: CASE REPORT AND MINI REVIEW

2017

Body lice transport B. recurrentis from man to man and humans are the only host. The presence of lice in Italy and an increasing number of cases in migrants can contribute to the onset of autochthonous cases. In this paper, we report a new case of Louse-borne Relapsing Fever (LBRF) diagnosed among migrants in Sicily exactly one year after the first case was recorded. We reviewed all cases reported in Europe from February 2016 until now. Our study identified two new cases of LBRF in migrants arrived in Europe: one who came from Somalia and one from Mali. Here we report data on a new case in Sicily. The number of migrants and refugees to transit in Sicily has increased, and this has led to th…

Monocyte to lymphocyte blood ratio in tuberculosis and HIV patients: Comparative analysis, preliminary data

2017

Recent data confirmed the hypothesis suggested by historical studies that the ratio of peripheral blood monocytes to lymphocytes (M/L) is associated with the risk of tuberculosis (TB) disease. We retrospectively analyzed the electronic health records of tuberculosis and HIV-positive patients who had followed day-care programs at the AIDS Center of the University of Palermo, Italy. 261 patients were recruited and divided into 6 groups as follows: healthy control group (HCG: 47 pts), latent HIV negative infected TB group (LIG, 43 pts), active HIV negative tuberculosis (TAG: 61 pts), treated tuberculosis HIV negative (TTG: 44 pts), HIV drug-naive patients tested TST and QFT-IT-negative with ne…
