The role of kidney dysfunction in COVID-19 and the influence of age.

COVID-19 is strongly influenced by age and comorbidities. Acute kidney injury (AKI) is a frequent finding in COVID-19 patients and seems to be associated to mortality and severity. On the other hand, the role of kidney dysfunction in COVID-19 is still debated.

Second outbreak of Trichinella pseudospiralis in Europe: clinical patterns, epidemiological investigation and identification of the etiological agent based on the western blot patterns of the patients' serum.

Trichinellosis is a zoonotic disease due to the ingestion of raw or undercooked meat from animals infected with the larvae of nematodes belonging to the genus Trichinella. In January-February 2015, an outbreak of trichinellosis occurred in Genoa, Northern Italy. The epidemiological link was traced back to a dinner served at an agritourism farm on 31 December 2014, where a majority of the 52 guests had consumed the 'beef' steak tartare.

Tocilizumab and steroid treatment in patients with COVID-19 pneumonia.

Introduction: Coronavirus disease 2019 (COVID-19) can lead to respiratory failure due to severe immune response. Treatment targeting this immune response might be beneficial but there is limited evidence on its efficacy. The aim of this study was to determine if early treatment of patients with COVID-19 pneumonia with tocilizumab and/or steroids was associated with better outcome.

Durability of first-line regimens including integrase strand transfer inhibitors (INSTIs): data from a real-life setting.

Objectives: To evaluate the durability of three integrase strand transfer inhibitors (INSTIs) and two NRTIs in ART-naive individuals.

Methods: The study design was observational. Patients were HIV-positive, ART-naive subjects starting raltegravir, elvitegravir/cobicistat or dolutegravir with two NRTIs.

Quality of life in an Italian cohort of people living with HIV in the era of combined antiretroviral therapy (Evidence from I.A.N.U.A. study-investigation on antiretroviral therapy).

The aims of this study were to assess the Health Related Quality of Life (HRQoL) of People Living with HIV/AIDS (PLWHA) who attend outpatient services in Genoa, Italy, and to evaluate the relationship between HRQoL and clinical factors, primarily: CD4+ cell count, viral load and HIV-Hepatitis C Virus (HCV) coinfection. A cross-sectional study was performed involving a sample of 943 consecutive patients. Firstly the EuroQol-Five Dimensions-Three Level (EQ-5D-3L) self-reported questionnaire was used to evaluate HRQoL, while socio-demographic information was collected using a separate self-administered questionnaire.

Incidence and progression to cirrhosis of new hepatitis C virus infections in persons living with human immunodeficiency virus.

Objective: To estimate the incidence of hepatitis C virus (HCV) seroconversion and the risk of severe fibrosis/cirrhosis in HCV seroconverters among persons with human immunodeficiency virus (HIV) infection.

Methods: We analysed data on 4059 persons with HIV enrolled in a cohort study in Italy.

Results: Incidence rate of seroconversion was 0.

Role of HCV-RNA decay and IP-10 levels after 48 hours of standard HCV therapy as predictors of rapid virological response.

Background And Objectives: Rapid virological response (RVR) is a critical end-point in the era of the new direct-acting antiviral agents (DAA). The aim of this study was to evaluate the predictive value in achieving RVR of HCV-RNA load and IP10 after 48 hours of standard anti HCV therapy.

Methods: HCV mono-infected and HIV/HCV co-infected patients naives to interferon were included.

IANUA: a regional project for the determination of costs in HIV-infected patients.

HIV treatment is based on combined antiretroviral therapy (cART) which has substantially improved survival, thus resulting in an increase in patient life expectancy as well as in the cost of HIV-related medical care. Therefore, several cost effectiveness studies were implemented worldwide, with one specifically in the Liguria region (Italy), to compare the annual economic expense in this area for HIV services, and the related improvement in patients' health. The IANUA project is intended to implement both cost-effectiveness and cost-utility analysis, therefore data related to clinical indicators and perceived health status were collected, the latter using a questionnaire based on the EQ-5D-3L.

Latent tuberculosis infection among a large cohort of medical students at a teaching hospital in Italy.

The surveillance of latent tuberculosis infection (LTBI) in both healthcare workers and healthcare students is considered fundamental for tuberculosis (TB) prevention. The aim of the present study was to estimate LTBI prevalence and evaluate potential risk-factors associated with this condition in a large cohort of medical students in Italy. In a cross-sectional study, performed between March and December 2012, 1511 eligible subjects attending the Medical School of the University of Genoa, trained at the IRCCS San Martino-IST Teaching Hospital of Genoa, were actively called to undergo the tuberculin skin test (TST).

Quality of life of people living with HIV, preliminary results from IANUA (Investigation on Antiretroviral Therapy) study.

Introduction: The introduction of combined antiretroviral treatment (cART) has reduced HIV-associated morbidity and mortality, and changed the patients' perspective of life. As a result, Health Related Quality of Life (HRQOL) has become a crucial clinical issue.

Objective: Assessment of HRQOL in a sample of Italian patients from IANUA study.

Latent tuberculosis infection and associated risk factors among undergraduate healthcare students in Italy: a cross-sectional study.

Background: The screening of both healthcare workers and students attending teaching hospitals for latent tuberculosis infection (LTBI) is recommended in hospitals of many countries with a low-incidence of TB, including Italy, as a fundamental tool of tuberculosis (TB) control programs. The aim of the study was to estimate the prevalence of LTBI and evaluate the main risk-factors associated with this condition in a cohort of healthcare Italian students.

Methods: In a cross-sectional study, performed between January and May 2012, 881 undergraduate students attending the Medical, Nursing, Pediatric Nursing and Midwifery Schools of the University of Genoa, trained at the IRCCS San Martino-IST Teaching Hospital of Genoa, were actively called to undergo the Tuberculin Skin Test (TST).

Durability of lopinavir/ritonavir monotherapy in individuals with viral load ≤50 copies/ml in an observational setting.

Background: The main objective is to evaluate the efficacy and durability of lopinavir-ritonavir monotherapy (LPV/r-MT) in virologically controlled HIV-positive individuals switching from combination antiretroviral therapy (cART).

Methods: Criteria to be included in this observational study were to have initiated for the first time LPV/r-MT after ≥2 consecutive HIV RNA≤50 copies/ml achieved on a ≥3-drug-including regimen. The main end points were time to virological rebound (VR; defined in two ways: time of first of two consecutive viral load [VL]>50 and >200 copies/ml), time to discontinuation/intensification and time to experience either a single VL>200 copies/ml or discontinuation/intensification (treatment failure [TF]).

Role of serum free light chains in predicting HIV-associated non-Hodgkin lymphoma and Hodgkin's lymphoma and its correlation with antiretroviral therapy.

A nested case-control study was performed within the Italian cohort of naïve to antiretroviral human immunodeficiency virus (HIV) patients (ICONA) cohort to evaluate the role of serum free light chains (sFLC) in predicting non-Hodgkin's lymphoma (NHL) and Hodgkin lymphoma (HL) in HIV-infected individuals. Of 6513 participants, 86 patients developed lymphoma and 46 of these (NHL, 30; HL, 16) were included in this analysis having stored prediagnostic blood. A total of 46 serum case samples matched 1:1 to lymphoma-free serum control samples were assayed for κ and λ sFLC levels and compared by using conditional logistic regression.

Determinants of access to experimental antiretroviral drugs in an Italian cohort of patients with HIV: a multilevel analysis.

Background: Identification of the determinants of access to investigational drugs is important to promote equity and scientific validity in clinical research. We aimed to analyze factors associated with the use of experimental antiretrovirals in Italy.

Methods: We studied participants in the Italian Cohort of Antiretroviral-Naive Patients (ICoNA).

A case of secondary syphilis presenting as optic neuritis.

Neurosyphilis is still a significant medical problem in developing countries and syphilitic ocular manifestations are often not diagnosed due to the lack of typical characteristics. We describe the case of a 59-year-old homosexual man with a 1-month history of decreased vision acuity in his left eye who was diagnosed with neurosyphilis and received treatment with intravenous penicillin G (16 million units in divided daily doses), with great improvement of visual acuity and CSF examination findings. The interest of this case is not only represented by the unusually early ocular involvement, but also by the rapid evolution of the disease into the secondary stage in a man who had had one at-risk homosexual relationship only 3 months before the onset symptoms.

Therapeutical aspects and outcome of HIV/HCV coinfected patients treated with pegylated interferon plus ribavirin in an Italian cohort.

Background: One-third of HIV-infected individuals suffer from chronic hepatitis C virus infection (HCV) in Europe. Recommendations from HCV-HIV International Panel advise current treatment with pegylated interferon plus ribavirin. We assessed the impact of interferon and ribavirin combination in 43 patients between 2002 and 2006.

Highly active antiretroviral therapy reduces the age-associated risk of dementia in a cohort of older HIV-1-infected patients.

Historically, older patients have shown a higher risk of HIV-1-associated dementia (HIVD). The objective of this study was to evaluate the association of aging with HIVD and minor cognitive motor disorders (MCMDs) during the late-highly active antiretroviral therapy (HAART) era and to analyze characteristics, predictive factors, and survival of older HIV-1-infected individuals affected by these disorders. A nested longitudinal study was designed for a cohort of HIV-1-infected individuals with neurological diseases.

[Survival, progression to AIDS and immunosuppression in HIV-positive individuals before and after the introduction of the highly active antiretroviral therapy (HAART)].

We evaluated the changes in the progression to death and AIDS and in the mean level of CD4 lymphocytes by calendar period in HIV-positive individuals before and after the introduction of HAART. Through data collected in a prospective cohort study (Italian Seroconversion Study) of 1899 HIV-infected persons with well estimated date of seroconversion, considered as time-zero of analysis, we calculated Kaplan-Meier curves and Cox models, allowing for staggered entries, to estimate the cumulative probability of survival and hazard-ratios (HR) for death and for AIDS by calendar period (1980-1996: pre-HAART era, 1997-1998: first HAART era, and 1999-2001: second HAART era), age at seroconversion, gender, and exposure category. During 17251 person-years, 660 HIV-positive patients developed AIDS and 510 died.

[HIV and related infections in Italian penal institutions: epidemiological and health organization note].

HIV and other infections represent an important health problem in Italian jails. In particular, HIV prevalence is high, due to the characteristics of the prison population, which is constituted by a large proportion of injecting drug users and foreigners. In addition, data from other countries suggest that risky behaviour are not uncommon during imprisonment, and transmission of HIV and other infection in this setting may also occur.

Papular-purpuric gloves and socks syndrome in HIV-positive patients.

Three HIV-positive women showed clinical signs of papular-purpuric gloves and socks syndrome and serologic evidence of acute Parvovirus B19 infection. The course of the disease was complicated by anemia and persistent skin lesions, probably related to inadequate immune response. Because anemia in AIDS patients may be due to many causes, the history of recent Parvovirus B19 infection is helpful in suggesting the etiologic diagnosis.

Possible malignant transformation of benign lymphoepithelial parotid lesions in human immunodeficiency virus-infected patients: report of three cases.

Benign lymphoepithelial parotid lesions (BLL) are intraparotid pathological changes that are commonly thought to be an early manifestation of human immunodeficiency virus (HIV) infection. It is not well known whether BLL may undergo malignant transformation into B cell lymphoma and may therefore be a sort of precancerous lesion. We report 3 cases of possible malignant transformation of BLL in HIV-infected patients.

Detection of apoptotic T lymphocytes in peripheral blood of human immunodeficiency virus (HIV)-infected subjects by apostain.

Apoptosis has been indicated as a mechanism of T cell depletion in HIV-infected subjects and useful in monitoring disease progression. We investigated for the presence of apoptotic T lymphocytes in 130 HIV subjects in various stages of disease by the newly developed cell permeant DNA dye Apostain. Blood was collected in EDTA, lysed in buffered ammonium chloride, fixed in freshly prepared 1% paraformaldehyde and stored in aliquots at -80 degrees C.

Expression of CD10 by human T cells that undergo apoptosis both in vitro and in vivo.

This study shows that human postthymic T cells express CD10 when undergoing apoptosis, irrespective of the signal responsible for initiating the apoptotic process. Cells from continuous T-cell lines did not normally express CD10, but became CD10(+) when induced into apoptosis by human immunodeficiency virus (HIV) infection and exposure to CD95 monoclonal antibody, etoposide, or staurosporin. Inhibitors of caspases blocked apoptosis and CD10 expression.

Serum IgG antibodies to human herpesvirus-6 (HHV-6) do not predict the progression of HIV disease to AIDS. Italian Seroconversion Study group.

Objectives: To evaluate if different levels of human herpesvirus 6 (HHV-6) antibodies can predict HIV disease progression.

Design: Longitudinal study of individuals with a documented date of HIV seroconversion.

Setting: Clinical centers located throughout Italy.
