Abstract

Background: Comparative data on mortality in COVID-19 patients treated with molnupiravir or with nirmatrelvir plus ritonavir are inconclusive. We therefore compared all-cause mortality in community-dwelling COVID-19 patients treated with these drugs during the Omicron era. Methods: Data collected in the nationwide, population-based, cohort of patients registered in the database of the Italian Medicines Agency (AIFA) were used. To increase completeness of the recorded deaths and date correctness, a cross-check with the National Death Registry provided by the Ministry of the Interior was performed. We included in this study all patients infected by SARS-CoV-2 treated within 5 days after the test date and symptom onset between February 8 and April 30, 2022. All-cause mortalities by day 28 were compared between the two treatment groups after balancing for baseline characteristics using weights obtained from a gradient boosting machine algorithm. Findings: In the considered timeframe, 17,977 patients treated with molnupiravir and 11,576 patients with nirmatrelvir plus ritonavir were included in the analysis. Most patients (25,617/29,553 = 86.7%) received a full vaccine course including the booster dose. A higher crude incidence rate of all-cause mortality was found among molnupiravir users (51.83 per 100,000 person-days), compared to nirmatrelvir plus ritonavir users (22.29 per 100,000 person-days). However, molnupiravir-treated patients were older than those treated with nirmatrelvir plus ritonavir and differences between the two populations were found as far as types of co-morbidities were concerned. For this reason, we compared the weight-adjusted cumulative incidences using the Aalen estimator and found that the adjusted cumulative incidence rates were 1.23% (95% CI 1.07%–1.38%) for molnupiravir-treated and 0.78% (95% CI 0.58%–0.98%) for nirmatrelvir plus ritonavir-treated patients (adjusted log rank p = 0.0002). Moreover, the weight-adjusted mixed-effect Cox model i

Abstract

Background and aims: Primary biliary cholangitis is an autoimmune biliary disease characterized by injury of bile ducts, eventually leading to cirrhosis and death. In most cases, anti-mitochondrial antibodies and persistently elevated serum alkaline phosphatase are the basis for the serological diagnosis. Anti-nuclear antibodies are also useful and may indicate a more aggressive diseases course. In patients in which anti-mitochondrial antibodies are not detected, an accurate diagnosis requires liver histology. This study aims at identifying specific biomarkers for the serological diagnosis of primary biliary cholangitis. Methods: Sera from patients affected by primary biliary cholangitis, primary sclerosing cholangitis, hepatitis C virus (with and without cryoglobulinemia), hepatocarcinoma and healthy donors were tested on a protein array representing 1658 human proteins. The most reactive autoantigens were confirmed by DELFIA analysis on expanded cohorts of the same mentioned serum classes, and on autoimmune hepatitis sera, using anti-PDC-E2 as reference biomarker. Results: Two autoantigens, SPATA31A3 and GARP, showed high reactivity with primary biliary cholangitis sera, containing or not anti-mitochondrial antibodies. Their combination with PDC-E2 allowed to discriminate primary biliary cholangitis from all tested control classes with high sensitivity and specificity. We found that GARP expression is upregulated upon exposure to biliary salts in human cholangiocytes, an event involving EGFR and insulin pathways. GARP expression was also detected in biliary duct cells of PBC patients. Conclusions: This study highlighted SPATA31A3 and GARP as new biomarkers for primary biliary cholangitis and unravelled molecular stimuli underlying GARP expression in human cholangiocytes

Abstract

Following the successful introduction of combined Antiretroviral Therapy (cART), a dramatic decrease in viral burden and opportunistic infections along with a consistent increase in life expectancy has been observed in Human Immunodeficiency Virus (HIV) infected patients [1]. This deep change in the HIV disease evolution has determined that HIV positive subjects were effectively monitored for several alterations of many tissue and organs due to HIV chronic disease and antiretroviral treatment for example, cardiovascular system, bone, adipose tissues, kidney and central nervous system represent the major target of these structural and functional damages during HIV infection. In particular, Cardiovascular Diseases (CVD) were considered important clinical complications in the HIV patient and represent a leading cause of death among HIV-positive patients, accounting for approximately 11% of the total deaths in this population [2]; the risk of CVD is higher in HIV positive individuals compared with HIV negative people, and particularly the reported Myocardial Infarction (MI) incidence in cohort study ranges from 3 to 11 cases per 1000 patients a year in HIV- positive individuals against 2 to 7 cases per 1000 patients-years in HIV-negative population [3,4]. Although initial studies indicated a higher prevalence of traditional CVD risk factors in HIV infected population [5,6] as a possible cause, the molecular mechanisms of increased CVD risk in HIV still remain incompletely defined and should be probably attributable to a combination of multiple factors, including both direct and indirect effects of HIV infection on metabolism. Evidence from experimental and observational studies [7,8] in recent years suggested a more important role of HIV itself in contributing to CVD. Endothelial dysfunction due to gp120, Tat and Nef proteins have been identified as a critical link between infection, inflammation, immune activation, atherosclerosis and cardiovascular system. Moreover, ART may play a role in the exacerbation of risk factors for CVD [9]; since the presentation of findings from the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) study in 2008 demonstrating a 90% increased risk of MI in HIV- positive individuals receiving ART regimens including Abacavir (ABC), subsequent studies, conducted by FDA [10], GlaxoSmithKline [11] and independent researchers [12], to investigate this risk have yielded conflicting results. Although more recent studies have shown an effective increased risk of CVD associated with use of ABC, many results did not reach statistical significance [13-17]. The absence of a demonstrated underlying biological mechanism for such a risk added interest and confusion about the question, as well as the higher prevalence of risk factors for CVD, such as renal impairment and substance abuse among abacavir recipients; in addition, a recent meta analysis suggests that Relative Risk (RR) for MI is increased within a 6 months exposure to ABC (RR=1.61; 95% confidence interval: 1.48–1.75) and in cART-naive population [18]. While the published evidence remains conflicting and a plausible biological mechanism for this potential association has not yet been identified, in the following study we have tried to verify whether, after introduction of ABC and its discontinuation in the contest of HAART deintensification, common metabolic markers CVD related such as glucose, LDL, HDL, total cholesterol and triglycerides and inflammatory biomarkers such as IL-6 and D-dimer could change in a small cohort of HIV-1 infected patients.

Abstract

Objectives: To investigate the long-term safety and efficacy of a treatment switch to dual ART with atazanavir/ritonavir+lamivudine versus continuing a standard regimen with atazanavir/ritonavir+2NRTI in virologically suppressed patients. Methods: ATLAS-M is a 96 week open-label, randomized, non-inferiority (margin -12%) trial enrolling HIV-infected adults on atazanavir/ritonavir+2NRTI, with stable HIV-RNA < 50 copies/mL and CD4 counts.200 cells/mm3. At baseline, patients were randomized 1:1 to switch to atazanavir/ritonavir+lamivudine or to continue the previous regimen. Here, we report the 96 week efficacy and safety data. The study was registered with ClinicalTrials.gov, number NCT01599364. Results: Overall, 266 subjects were enrolled (133 in each arm). At 96 weeks, in the ITT population, patients free of treatment failure totalled 103 (77.4%) with atazanavir/ritonavir+lamivudine and 87 (65.4%) with triple therapy (difference +12.0%, 95% CI +1.2/+22.8, P=0.030), demonstrating the superiority of dual therapy. Two (1.5%) and 9 (6.8%) virological failures occurred in the dual-therapy arm and the triple-therapy arm, respectively, without development of resistance to any study drug. Clinical adverse events occurred at similar rates in both arms. A higher frequency of grade 3-4 hyperbilirubinemia (66.9% versus 50.4%, P=0.006) and hypertriglyceridaemia (6.8% versus 1.5%, P=0.031) occurred with dual therapy, although this never led to treatment discontinuation. A significant improvement in renal function and lumbar spine bone mineral density occurred in the dual-therapy arm. The evolution of CD4, HIV-DNA levels and neurocognitive performance was similar in both arms. Conclusions: In this randomized study, a treatment switch to atazanavir/ritonavir+lamivudine was superior over the continuation of atazanavir/ritonavir+2NRTI in virologically suppressed patients, with a sustained benefit in terms of improved renal function and bone mineral density.

Abstract

Background: Combination ART (cART)-related toxicities and costs have prompted the need for treatment simplification. The ATLAS-M trial explored 48 week non-inferior efficacy of simplification to atazanavir/ritonavir + lamivudine versus maintaining three-drug atazanavir/ritonavir-based cART in virologically suppressed patients. Methods: We performed an open-label, multicentre, randomized, non-inferiority study, enrolling HIV-infected adults on atazanavir/ritonavir+two NRTIs, with stable HIV-RNA <50 copies/mL and CD4+>200 cells/mm3. Main exclusion criteria were hepatitis B virus coinfection, past virological failure on or resistance to study drugs, recent AIDS and pregnancy. Patients were randomly assigned 1:1 to either switch to 300mg of atazanavir/ 100mg of ritonavir once daily and 300mg of lamivudine once daily (atazanavir/ritonavir+lamivudine arm) or to continue the previous regimen (atazanavir/ritonavir+two NRTIs arm). The primary study outcome was the maintenance of HIV-RNA <50 copies/mL at week 48 of the ITT-exposed (ITT-e) analysis with switch"failure. The non-inferiority margin was 12%. This study is registered at ClinicalTrials.gov, number NCT01599364. Results: Between July 2011 and June 2014, 266 patients were randomized (133 to each arm). After 48 weeks, the primary study outcome was met by 119 of 133 patients (89.5%) in the atazanavir/ritonavir+lamivudine arm and 106 of 133 patients (79.7%) in the atazanavir/ritonavir+two NRTIs arm [difference atazanavir/ritonavir+ lamivudine versus atazanavir/ritonavir+two NRTIs arm: +9.8% (95% CI+1.2 to+18.4)], demonstrating non-inferiority and superior efficacy of the atazanavir/ritonavir+lamivudine arm. Virological failure occurred in two (1.5%) patients in the atazanavir/ritonavir+lamivudine arm and six (4.5%) patients in the atazanavir/ritonavir+ two NRTIs arm, without resistance selection. A similar proportion of adverse events occurred in both arms. Conclusions: Treatment simplification to atazanavir/rito

Abstract

Combination abacavir/lamivudine/dolutegravir (ABC/3TC/DTG) is approved as a first-line treatment for antiretroviral naïve patients. This report investigated the immunovirological outcome and total HIV-1 DNA decay in a small cohort of naïve HIV-1-positive patients treated with this regimen. In the presence of viral suppression and increased lymphocyte T CD4+ cells, the quantitative analysis of total HIV-1 DNA content revealed a significant decay after 12 months of treatment. Subsequently, we deintensificated the treatment of these patients from (ABC/3TC/DTG) to lamivudine plus dolutegravir (3TC/DTG) after 12 months of virological suppression, as a strategy of "induction-maintenance" therapy. The analysis of HIV-1 RNA viral load, total HIV-1 DNA, CD4+ T lymphocyte count and CD8+ HLA-DR+ T lymphocyte percentage after a mean 3.5 months of therapy deintensification showed no significant difference with respect to data detected after 12 months of ABC/3TC/DTG treatment in the presence of continuous viral suppression. These results indicate that the deintensification of highly active antiretroviral therapy (HAART) from ABC/ 3TC/DTG to 3TC/DTG effectively controls HIV-1 replication and in the early period does not induce any significant variations of total HIV-1 DNA. This suggests that HAART deintensification might be proposed as a therapeutic evolution in the treatment of HIV-1 infection.

Abstract

We report the first Italian case of Mycobacterium chimaera disseminated infection in a patient with a history of cardiac surgery. The patient was initially diagnosed with sarcoidosis and started on immunosuppressive therapy. Ten months later she developed a vertebral osteomyelitis: M. chimaera was isolated from bone specimen. A review of the literature shows that M. chimaera infection occurs specifically in this population of patients, due to contamination of heater-cooler units used during cardiosurgery. Devices responsible for the transmission were produced by Sorin Group Deutschland. Mycobacterium chimaera infection should be included in the differential diagnosis for patients undergoing cardiac surgery.

Abstract

Cockayne syndrome (CS) is a rare DNA repair defective hereditary disorder characterized by severe developmental and neurological alterations and early death. The molecular bases are still unknown. The proteins responsible of CS, CSA and CSB, are known to be involved in the repair of UV damage from the transcribed strand of active genes as well as in the repair of oxidatively induced DNA damage. Evidence has been provided that human CS cells present an altered redox balance with increased steady-state levels of intracellular ROS and mitochondrial dysfunction (Pascucci et al., 2012; Scheibye-Knudsen et al., 2012). Here, we show that the mitochondrial dysfunction of CS cells is not due to increased accumulation of oxidatively induced DNA damage in the mitochondrial genome. Both basal and induced 8-oxoguanine (8-OH-Gua) mitochondrial DNA levels in CS cells did not exceed those observed in normal fibroblasts whereas increased levels of 8-OH-Gua were confirmed in the nuclear genome of CS cells. A defect in autophagy has been proposed as the underlying mechanism for mitochondrial dysfunction in CS-B cells (Scheibye-Knudsen et al., 2012). To investigate whether autophagy/mitophagy were affected in the absence of CSA, we used a cell line stably expressing the ectopic wild-type CSA (wtCSA) protein obtained from the SV40-transformed CS-A cell line CS3BE. Following exposure to carbonyl cyanide m-chlorophenyl hydrazine (CCCP), that induces mitochondria uncoupling, CS-A cells showed an accelerated mitophagic flux, seen by LC3 accumulation in the presence of lysosomal inhibitors, translocation of Parkin and stabilization of PINK at mitochondria. Overexpression of Parkin protected wt cells from the killing effects of CCCP but much less efficiently CS-A cells. Mitochondria of CS cells presented an altered morphology and distribution. Mitochondria were mostly perinuclear with a less elongated shape then mitochondria of wt cells. Following CCCP exposure in CS-A cells fewer mitochondria were observed with altered morphology. On the basis of these findings we can conclude that in CS-A cells the key players of mitophagy correctly signal altered mitochondria to degradation and therefore alteration of mitophagy does not account for mitochondrial dysfunction. The mechanisms underlying the defective protection from CCCP killing by Parkin are currently under investigation.

Abstract

We have evaluated CD4+-guided HAART interruption in 46 HIV+ patients with CD4+500/microl and viral load undetectable since at least 3 years. This strategy resulted effective in a long mean period of treatment interruption (18 months) and safe. In fact, during the follow-up period there were no deaths, nor opportunistic infections. Reintroduction of HAART was due to: CD4+ fall under 200/microl (6 cases), acute retroviral syndrome (4), individual choice (2), asymptomatic thrombocytopenia (1), peripheral neuropathy (1), pregnancy (1). A low CD4+ nadir level was correlated with a short period of treatment interruption.

Abstract

Mycoplasma hominis and Ureaplasma urealyticum are frequently isolated from the cervical and vaginal tracts of HIV-negative asymptomatic women. Published data lack indisputable conclusions and doubts still exist as to whether these mycoplasmas are pathogens or mere co-factors associated with genital infections. We therefore conducted a surveillance study to investigate the prevalence of genital mycoplasmas in HIV-1 positive women (110 patients), attending the outpatient Infectious Diseases Clinic of our tertiary referral Hospital, by speculum examination, PAP test, endocervical and vaginal swabs obtained by gynaecologists. Ureaplasma urealyticum was isolated from the cervix of 45 women (41%). Mycoplasma hominis was recovered from 12 women (11%), in four of whom it was isolated at the same time from the vagina. PAP test results ruled out subclinical cervicitis in all women. Bacterial vaginosis, assessed by Amsel criteria and the Nugent score, was absent in all women. Our data show that the mycoplasmas in question are found in the lower genital tract of asymptomatic HIV-1-positive women at a frequency similar to that reported in the HIV-negative female population, and make a role for these microorganisms unlikely in the aetiology of cervico-vaginal infections also in this particular patient population.

Abstract

In immunocompromised patients, Aspergillus infections are important causes of morbidity and mortality. We describe a patient with cryoglobulinemic vasculitis who developed disseminated invasive aspergillosis with thyrotoxicosis caused by Aspergillus fumigatus. The diagnosis was based upon radiological, microbiological and pathological findings. The patient was treated successfully with voriconazole and caspofungin treatment followed by total thyroidectomy. We provide an overview of published reports on Aspergillus thyroiditis with an emphasis on therapeutic approaches. [ABSTRACT FROM AUTHOR]

Abstract

A case of inflammatory pseudotumor in a 22-Year-old man is described. Symptoms and signs showed high fever and prominent cervical lymphadenopathy; laboratory findings were consistent with an acute inflammatory process. Diagnosis was reached through a lymph node biopsy which allowed a definitive diagnosis and ruled out several mimicking pathological processes such as malignant lymphoma, infectious diseases and autoimmune disorders. Inflammatory pseudotumor should be included in the differential diagnosis of patients with persistent fever and lymph node enlargement.
