Does COVID-19 Vaccination with BNT162b2 Influence HIV-Related Immunological and Virological Markers? Data from 235 Persons Living with HIV at Cotugno Hospital, Naples, Italy: Immune Response After Second and Third Doses, and Influence on Immunovirological Markers.

Few data are available on the impact of COVID-19 vaccination on CD4 counts and HIV-RNA in persons living with HIV (PLWH). We present the data of 235 PLWH who were vaccinated with BNT162b2 in March 2021-February 2022 at the "Cotugno" hospital in Naples. PLWH treated at the "Cotugno" hospital, who were vaccinated at the hospital vaccination center, without prior COVID-19 and for whom immunological/virological data were available in the last 12 months and in the 6 months after vaccination were included. Antispike Ab were available for 187 and 64 PLWH after the second and third doses: PLWH with antispikes >33 binding antibodies units (BAU)/mL increased from 91% to 98%. Antinucleocapsid Ab performed in 147 and 56 patients identified 19 (13%) asymptomatic/paucisymptomatic COVID-19 infections after the second dose and an additional 15 (27%) after the third dose. Immunological/virological data were collected before vaccination (T0), after the second dose (T1), and after the third dose (T2). The absolute number of CD4 increased after the third dose (median 663, 657, and 707 at T0, T1, and T2; p < 0.000 T0 vs. T2). The proportion of patients with HIV-RNA <50 copies/mL increases significantly after the second dose (73%; 85.7%; 87.7%; p < 0.000 T0 vs. T2). The presence of COVID-19 asymptomatic/paucisymptomatic infections (demonstrated by the presence of antinucleocapsid Ab) significantly increases SARS-CoV-2 antispike Ab after second dose, but not after third dose. Asymptomatic/paucisymptomatic COVID-19 infections do not have influence on CD4 cell number and HIV-RNA level. Similarly, the presence of not-controlled HIV-RNA (HIV-RNA >50 copies/mL) does not influence antispike Ab response. According to our data, the response to SARS-CoV2 vaccination is effective in people living with HIV. Vaccination against COVID-19 appears to positively affect immunological and virological levels in people living with HIV.

Epidemiology of HCV and HBV in a High Endemic Area of Southern Italy: Opportunities from the COVID-19 Pandemic-Standardized National Screening or One Tailored to Local Epidemiology?

The COVID-19 pandemic led to the hospitalization of an unselected population with the possibility to evaluate the epidemiology of viral hepatitis. Thus, a retrospective multicenter study was conducted in an area of Southern Italy with the aim of assessing the prevalence of HCV and HBV markers and the ability of current screening program to capture cases. We evaluated 2126 hospitalized patients in seven COVID Centers of Naples and Caserta area in which 70% of the Campania population lives. HBsAg and HCV-Ab prevalence was 1.6% and 5.1%, respectively, with no differences between gender. Decade distribution for birth year shows a bimodal trend of HCV prevalence, with a peak (11.6%) in the decade 1930-1939 and a second peak (5.6%) for those born in 1960-1969. An analysis of the screening period imposed by the Italian government for those born between 1969 and 1989 shows that only 17% of cases of HCV infection could be captured. A small alignment of the screening period, i.e., those born from 1960 to 1984, would capture 40% of cases. The data confirm the high endemicity of our geographical area for hepatitis virus infections and underline the need for a tailored screening program according to the regional epidemiology.

Hospital admissions for HIV-infected prisoners in Italy.

Purpose The purpose of this paper is to give a description of the clinical conditions and patient demographics of inpatient admissions of human immunodeficiency virus (HIV)-infected inmates in three hospital wards that provide hospital care for inmates in Italy. Design/methodology/approach This is a retrospective review of hospital medical admissions of patients living with HIV from January 1 to December 31, 2014, in three Italian referral centers for hospitalization of inmates. Findings A total of 85 admissions for 85 different HIV-infected inmates occurred in 2014 in the three centers participating to the study. Most patients (54.1 percent) were co-infected with hepatitis C. Discharge diagnosis largely varied ranging from common HIV-related co-morbidities to completely independent diagnosis. The most commonly observed discharge diagnoses were chronic hepatitis C, liver cirrhosis, opiate dependence and thrombocytopenia. Originality/value Discharge diagnosis between HIV-infected inmates and HIV-infected patients in freedom are strikingly and significantly different. A large number of hospitalized HIV-infected inmates were affected by chronic viral hepatitis and liver cirrhosis; this is probably a direct consequence of the high prevalence of HCV and/or HBV co-infections in the inmate population in Italy. In addition, a significantly lower proportion of cancer diagnosis was observed among inmates; this is possibly justified by the fact that in our Italian settings when HIV infection is at advanced stages or if cancer treatment is started those affected are released from prison and can continue their diagnostic and treatment follow-up in freedom.

Aortic Valve Endocarditis Caused by Abiotrophia defectiva: Case Report and Literature Overview.

UNLABELLED: Abiotrophia defectiva or nutritionally variant Streptococcus (NVS) are a rare but important cause of infectious endocarditis, with high rates of bacteriological failure and mortality. We report the case of a 74-year-old man admitted for fever, fatigue and general malaise in the absence of any underlying cardiac, immunosuppressive illness and previous dental manipulations. Transthoracic and transesophageal echocardiogram revealed bacterial vegetation and significant aortic stenosis and regurgitation. Initial blood culture reported gram-positive cocci in chains, subsequently identified as A. defectiva. The patient completed 6 weeks of antibiotic therapy with ampicillin, with a significant decrease of serum inflammatory markers. He refused cardiac surgery and had relapsing endocarditis with positive blood culture for the same pathogen. The patient was then submitted to double-valve cardiac surgery, obtaining a prompt resolution of clinical signs and symptoms, without other relapse or any complications. CONCLUSION: Infectious diseases caused by A. defectiva are extremely rare illnesses. Due to the difficult isolation of the pathogen and the slow clinical progression, clinicians should be aware of this bacterium when dealing with blood culture-negative infective endocarditis.

Different impact of anti-retroviral regimen containing protease inhibitors on development of HIV-related Kaposi sarcoma.

BACKGROUND: The incidence of Kaposi's sarcoma (KS), an AIDS-related malignancy, has dramatically decreased in the Highly Active Anti-retroviral Therapy (HAART) era. However, KS remains the second most frequent tumor in HIV-infected patients worldwide and has become the most common cancer in the sub-Saharan Africa. Experimental studies have demonstrated a direct anti-neoplastic effect of HAART, and overall of protease inhibitors (PIs), on KS. CASE REPORT: We describe five cases of KS in HIV-infected patients on HAART regimen, containing PIs as atazanavir/r (ATV/r), darunavir/r (DRV/r), lopinavir/r (LPV/r) and fosamprenavir (fAMP/r). CONCLUSION: Clinical and experimental observations support the hypothesis that PIs may play an important role in prevention and treatment of KS. In our study, the treatment with PIs of recent generation was not protective against the development of KS. Therefore, it could be necessary to re-evaluate the therapeutic effects of PIs and their role in the development and treatment of KS in HIV-infected patients.

Hepatitis B virus DNA quantitation and detection of core promoter, precore and polymerase mutations in chronic hepatitis B: evaluation and clinical usefulness of three new commercial assays.

BACKGROUND: HBV-DNA quantitation, the HBe antigen status and the appearance of mutations in the core promoter, precore and polymerase regions are important elements in the management of chronic HBV infection. METHODS: We performed a technical evaluation of 3 new kits, affigene HBV VL, affigene HBV mutant VL and affigene HBV DE/3TC assays (Sangtec Molecular Diagnostics) in comparison with the Amplicor HBV Monitor assay (Manual Test, Roche), direct sequencing and direct sequencing/Inno-LIPA HBV DR (Innogenetics), respectively. We evaluated the clinical application of these tests in the management of patients with chronic (HBeAg positive) hepatitis B. Serial sera of 11 chronic HBeAg positive patients were studied before, during and after lamivudine/interferon treatment. RESULTS: HBV-DNA quantitation detected with affigene HBV VL showed a high correlation with the Amplicor HBV Monitor test (r=0.85). affigene HBV mutant VL (positions G1764A, G1896A) and affigene HBV DE/3TC (positions rtL180M, rtM204V/I) were able to detect a low presence of mutants in a mixed population (wild type and mutant) compared to direct sequencing and Inno-LIPA HBV DR, which identified only the dominant population. CONCLUSIONS: These three sensitive assays, performed with the same DNA extraction, give clinicians useful information for the management of chronic hepatitis B and for timing treatment.
