Objectives We aimed to investigate and compare the efficacy and safety of two dolutegravir-based two-drug regimens: dolutegravir + lamivudine versus dolutegravir + rilpivirine. Methods We analysed a cohort of people living with HIV (PLWHIV) switching to dolutegravir + lamivudine or dolutegravir + rilpivirine. We excluded from the analysis PLWHIV with no available pre-switch genotypic test or with a known resistance mutation to one of the study drugs. We evaluated incidence of virological failure (VF) and treatment discontinuation (TD), as well as changes in immunological and metabolic parameters. Results We enrolled 592 PLWHIV: 306 in the lamivudine group and 286 in the rilpivirine group. We observed nine VFs in the lamivudine group [1.4 VF per 100 patient-years of follow-up (PYFU)] and four VFs in the rilpivirine group (0.6 VF per 100 PYFU). Subsequent genotypic analysis showed no acquired resistance-associated mutations in those experiencing VF. Estimated probability of maintaining virological suppression at 144 and 240 weeks were 96.6% and 92.7%, respectively, in the lamivudine group and 98.7% and 98.7%, respectively, in the rilpivirine group (log-rank P  = 0.172). The estimated probability of maintaining study regimen at Week 240 was 82.3% in the lamivudine group and 85.9% in the rilpivirine group (log-rank P  = 0.018). We observed a significant improvement in CD4+ cell count at Week 240 in the lamivudine group (P  = 0.012); in the rilpivirine group we registered a significant increase in CD4/CD8 ratio (P  = 0.014). Conclusions Both analysed strategies are effective and safe as switch strategies in clinical practice, with a low incidence of VF and a favourable immunological recovery, even in the long term.

Abstract Madelung’s disease or multiple symmetric lipomatosis (MSL) is a rare disorder of unknown etiology which typically presents symmetrically subcutaneous accumulation of non-encapsulated adipose tissue which slowly grows around the neck, upper part of the arms, pelvis, back and thigh. This disease is also frequently associated with hepatopathy, glucose intolerance, hyperuricemia, and malignant tumors of the upper airways. Nevertheless, only one description of malignant transformation of Madelung’s disease has been presented in literature. Here, we report a case of liposarcomatous transformation of Madelung’s disease in a 59-year-old Italian woman with a coincidental diagnosis of breast cancer.

The Aim of this study is to assess the cardiovascular safety of doravirine/lamivudine/tenofovir disoproxil fumarate (DOR/3TC/TDF). We analyzed data from 37 virologically suppressed people living with HIV starting DOR/3TC/TDF, collecting viro-immunological and metabolic parameters as well as the 10-year risk of cardiovascular disease (10Y-CD) using both the Framingham risk score and D:A:D score.After 48 weeks, we observed a significant reduction in 10Y-CD both via the Framingham score (-0.7, p = .021) and the D:A:D score (-0.41, p = .012). After 96 weeks, we registered a significant reduction in 10Y-CD calculated via the D:A:D score (-0.98, p = .009). Regarding serum lipid markers, after 48 weeks we observed a significant reduction in total cholesterol (-17 mg/dL, p < .001), triglycerides (-21 mg/dL, p = .015), and LDL cholesterol (-8 mg/dL, p = .022). After 96 weeks, we registered a significant reduction in total cholesterol (-19 mg/dL, p < .001). DOR/3TC/TDF has shown a favorable metabolic profile, with a significant reduction in 10Y-CD, independently from the use of lipid-lowering drugs.

Vicarious stigma shows how indirect stigmatizing experiences can lead people living with HIV (PLWH) to feel discriminated against. We enrolled 350 PLWH, who were administered a 17-item questionnaire to investigate a subjective experience of stigma experienced in the hospital care setting. We found that at least once 215 PLWH (61.4%) did not want the HIV exemption indicated on the prescription for a specialist medical visit, 232 PLWH (66.3%) never used their HIV-related exemption to make a specialist medical visit, 230 PLWH (65.7%) avoided undergoing a medical assessment outside the infectious disease clinics and 241 patients (68.9%) felt unwelcome during a specialist medical visit. Moreover, 241 patients (61.1%) had heard at least once stories of health workers who did not want to touch PLWH, 213 patients (60.9%) had heard stories at least once of PLWH who had been mistreated by hospital staff, 180 patients (51.4%) had at least once heard stories about PLWH being refused treatment and services and 257 patients (73.4%) had at least once heard stories about health workers talking publicly about PLWH. This is a little explored area, especially regarding the vicarious stigma faced by PLWH. Our findings indicate the importance of combating HIV-related stigma for the wellbeing of PLWH.

Background: High incidence mpox rates suggest asymptomatic individuals may contribute to virus transmission. We undertook this study to assess the seroprevalence of IgG anti-MPXV in a cohort of asymptomatic PLWH, to analyze the size of the phenomenon of asymptomatic infections., Materials and Methods: From October 2022 to March 2023 we serially collected serum samples from PLWH attending our Clinic. IgG against MPXV have been assessed on stored cryopreserved samples with an ELISA. Only people with no previous reported vaccine against smallpox or mpox nor previous clinical manifestations consistent with a mpox diagnosis were included., Results: 285 PLWH were included. Twenty-one participants tested positive for IgG anti MPXV (7.37 %, 95 % CI 4.62-11.0). Seropositivity was predominant in male (15/285, 71.4) with a small fraction of female (6/285,28.6 %) and PWID (1/285,4.8 %)., Conclusions: Our findings suggest the possibility of an asymptomatic course of the mpox infection even in populations beyond traditional high-risk groups., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Metabolic dysfunction-associated fatty liver disease (MAFLD) has become a major health risk and a serious worldwide issue. MAFLD typically arises from aberrant lipid metabolism, insulin resistance, oxidative stress, and inflammation. However, subjacent causes are multifactorial. The gut has been proposed as a major factor in health and disease, and over the last decade, bacterial strains with potentially beneficial effects on the host have been identified. In vitro cell models have been commonly used as an early step before in vivo drug assessment and can confer complementary advantages in gut and liver health research. In this study, several selected strains of the order Bacteroidales were used in a three-cell line in vitro analysis (HT-29, Caco-2, and HepG2 cell lines) to investigate their potential as new-generation probiotics and microbiota therapeutics. Antimicrobial activity, a potentially useful trait, was studied, and the results showed that Bacteroidales can be a source of either wide- or narrow-spectrum antimicrobials targeting other closely related strains. Moreover, Bacteroides sp. 4&#95;1&#95;36 induced a significant decrease in gut permeability, as evidenced by the high TEER values in the Caco-2 monolayer assay, as well as a reduction in free fatty acid accumulation and improved fatty acid clearance in a steatosis HepG2 model. These results suggest that Bacteroidales may spearhead the next generation of probiotics to prevent or diminish MAFLD., (© 2024. The Author(s).)

Echinococcal disease (hydatid disease (HD) is an endemic parasitosis caused by Echinococcus granulosus in the larval stage, and it is typically due to the production of unilocular cystic lesions, usually involving the liver for the majority of patients and the lungs in 25%, but also any other organs can be potentially involved in developing echinococcal disease. We report a case of extrahepatic, retroperitoneal echinococcal disease, caused by Echinococcus granulosus. The patient underwent a surgical removal of the abdominal mass, revealed by abdominal ultrasound and computerized tomography scanning, and in the founded clinical and radiological suspicion of echinococcal disease, multiple bioptical samples were sent for microbiological analysis and albendazole therapy was started; Echinococcus granulosus protoscolices were found on the bioptical sample, and the diagnosis was successfully confirmed. According to the current parasitology literature on echinococcal disease, extrahepatic localization, although rare, can be found, and it should be considered in the differential diagnosis of an abdominal mass when epidemiological risk factors and anamnestic data are present, regardless of the usual site of the disease., (© 2023.

Objective: Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), is the most prevalent liver disease globally, yet no therapies are approved. The effects of Escherichia coli Nissle 1917 expressing aldafermin, an engineered analog of the intestinal hormone FGF19, in combination with dietary change were investigated as a potential treatment for MASLD., Methods: MASLD was induced in C57BL/6J male mice by American lifestyle-induced obesity syndrome diet and then switched to a standard chow diet for seven weeks. In addition to the dietary change, the intervention group received genetically engineered E. coli Nissle expressing aldafermin, while control groups received either E. coli Nissle vehicle or no treatment. MASLD-related plasma biomarkers were measured using an automated clinical chemistry analyzer. The liver steatosis was assessed by histology and bioimaging analysis using Fiji (ImageJ) software. The effects of the intervention in the liver were also evaluated by RNA sequencing and liquid-chromatography-based non-targeted metabolomics analysis. Pathway enrichment studies were conducted by integrating the differentially expressed genes from the transcriptomics findings with the metabolites from the metabolomics results using Ingenuity pathway analysis., Results: After the intervention, E. coli Nissle expressing aldafermin along with dietary changes reduced body weight, liver steatosis, plasma aspartate aminotransferase, and plasma cholesterol levels compared to the two control groups. The integration of transcriptomics with non-targeted metabolomics analysis revealed the downregulation of amino acid metabolism and related receptor signaling pathways potentially implicated in the reduction of hepatic steatosis and insulin resistance. Moreover, the downregulation of pathways linked to lipid metabolism and changes in amino acid-related pathways suggested an overall reduction of oxidative stress in the liver., Conclusions: These data support the potential for using engineered microbial therapeutics in combination with dietary changes for managing MASLD., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Regimens containing darunavir are one of the first one with two drugs that demonstrated good efficacy as a simplification strategy. We wanted to describe the characteristics of patients followed in our center on a dual therapy regimen containing darunavir evaluating the metabolic aspects during follow-ups. We collected data from 208 patients switching to lamivudine plus darunavir with either ritonavir or cobicistat between 2010 and 2019. In all patients we found an increase in low-density lipoprotein (LDL), with no rising in creatinine, total cholesterol, or triglycerides. Twenty-five patients reached 120 weeks of follow-up. In these patients, no significant metabolic changes were described without concomitant treatment with drugs for dyslipidemia. These regimens seem to be more tolerable in metabolic profile compared with the data concerning three-drug therapies, leading only to a slight increase in LDL. The main reason for discontinuation was for a single-tablet therapy. None of the patients started treatment for dyslipidemia.

Evidence accumulated during past years confirm that people living with HIV (PLWH) still have to deal with comorbidities and chronic complications that can increase physical and psychological issues and can affect daily functioning, quality of life and mental health. Moreover, during the COVID-19 pandemic PLWH proved to be a population at increased risk of psychological distress. We explored the ongoing issues and the characteristics of the mental health interventions for which a cohort of Italian PLWH interacted with a psychologist over the past five years. We analysed a dataset that included 61 PLWH who underwent a psychological intervention between 2018 and 2022. We compared different frequencies in characteristics of mental health interventions according to different demographic and clinical variables, psychopathological symptoms and time of the request for intervention. We showed that psychopathological symptoms most frequently reported by patients were anxiety (55.7%), and depression (49.2%). Furthermore, we reported that most our patients undertook occasional psychological support meetings (31%), sought an intervention after the outbreak of the COVID-19 pandemic (62.3%) and complained about disclosure issues (48.5%). Disclosure issues were mainly reported by younger PLWH ( p  = 0.002) with a shorter disease ( p  = 0.031) and treatment history ( p  = 0.032), and higher interpersonal sensitivity ( p  = 0.042). It seems fundamental to integrate psychological interventions into the care of PLWH, to give particular attention to PLWH with risky demographic, clinical and mental health factors and to pay special attention to emergency conditions (such as the COVID-19 pandemic) and the most widespread issues to create ad hoc interventions.

Thanks to the modern ARV regimens and the fact that the morbidity and mortality of metabolic syndrome increases with age, clinicians are continuously researching effective and safe antiretroviral regimens with low impact on the lipid profile. Doravirine (DOR) is the latest non-nucleoside reverse-transcriptase inhibitor (NNRTI) that shows long-term safety and tolerability and a favorable lipid profile. The aim of this study is to assess the impact of DOR-based three-drug regimens on the lipid profile in clinical practice. We retrospectively analyzed a cohort of 38 treatment-experienced, virologically suppressed people living with HIV (PLWH) switching to this regimen, following the eligibility criteria. We carried out comparison analysis of immunological and metabolic parameters between baseline and 48 weeks of follow up. In our cohort of treatment-experienced, virologically suppressed PLWH, three-drug regimens with DOR showed good efficacy and a positive profile on lipid metabolism at 48 weeks of follow up.

Introduction: Human immunodeficiency virus type 1 (HIV) transmission mostly occurs through the genital and intestinal mucosae. Although HIV-1 transmission has been extensively investigated, gaps remain in understanding the initial steps of HIV entry through the colonic mucosa. We previously showed that HIV can selectively trigger mononuclear phagocytes (MNP) to migrate within colonic epithelial cells to sample virions. Mucosal exposure to human seminal plasma (HSP), rich in pro- and anti-inflammatory cytokines, chemokines and growth factors, may as well induce alterations of the colonic mucosa and recruit immune cells, hence, affecting pathogen sampling and transmission., Methods: Here, we studied the role of HSP on the paracellular intestinal permeability by analyzing the distribution of two proteins known to play a key role in controlling the intestinal barrier integrity, namely the tight junctions-associated junctional adhesion molecule (JAM-A) and the adherents junction associated protein E-cadherin (E-CAD), by immunofluorescence and confocal microscopy. Also, we evaluated if HSP promotes the recruitment of MNP cells, specifically, the CD11c and CD64 positive MNPs, to the apical side of the human colonic mucosa. At this scope, HSP of HIV-infected and uninfected individuals with known fertility status was tested for cytokines, chemokines and growth factors concentration and used in an ex vivo polarized colonic tissue culture system to mimic as closely as possible the physiological process., Results: HSP showed statistically significant differences in cytokines and chemokines concentrations between the three groups of donors, i.e. HIV infected, or uninfected fertile or randomly identified. Nevertheless, we showed that in the ex vivo tissue culture HSP in general, neither affected the morphological structure of the colonic mucosa nor modulated the paracellular intestinal permeability. Interestingly, CD11c+ MNP cells migrated to the apical surface of the colonic epithelium regardless, if incubated with HIV-infected or -uninfected HSPs, while CD64+ MNP cells, did not change their distribution within the colonic mucosa., Discussion: In conclusion, even if HSP did not perturb the integrity of the human colonic mucosa, it affected the migration of a specific subset of MNPs that express CD11c towards the apical side of the colonic mucosa, which in turn may be involved in pathogen sampling., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Baratella, Iannone, Cavarelli, Foglieni, Viganò, Moog, Elmore, Nozza, Alfano, Salonia, Dispinseri and Scarlatti.)

Aim of this study is to assess the impact of doravirine (DOR)-based regimens on cardiovascular risk in treatment-experienced people living with HIV (PLWHIV). We retrospectively analyzed a cohort of 40 treatment-experienced PLWHIV switching to a DOR-based three-drug regimen, evaluating 10-year risk of manifesting clinical cardiovascular diseases (CD) through the Framingham Risk Score at baseline, 12, and 24 weeks of follow-up. At baseline, median predicted 10-year risk of cardiovascular disease (10Y-CD) was 8.0% (interquartile range 4.0-13.0). After 12 weeks, we observed a significant reduction in 10Y-CD (mean decrease -2.21, p  = .012); similarly, we observed a nonsignificant reduction at week 24 ( p  = .336). Regarding metabolic parameters, after 24 weeks we observed a significant reduction in total cholesterol (median change -8.8 mg/dL, p  = .018), low-density lipoprotein cholesterol (median -9.5 mg/dL, p  = .007), and triglycerides (median -19.8 mg/dL, p  < .001). Our results show a favorable metabolic impact of DOR-based regimens along with a promising reduction in 10-year risk of cardiovascular disease.

Cabotegravir and rilpivirine are the first drugs to be approved as injectable therapy to treat individuals with HIV. Despite encouraging results, the guidelines specify strict criteria for eligibility that could limit the feasibility of this strategy. We collected the clinical data of HIV-positive patients who were being treated at a single, third-level center in Italy. All patients were on stable therapy and showed suppressed viral load on their most recent analyses. We performed a cross-sectional analysis of the clinical and viro-immunological characteristics of this population and excluded patients who had previous virological failures, resistance-associated mutations (RAMs) to rilpivirine or integrase inhibitors in the historical genotype, hepatitis B infection, absence of previous genotypes, and the coexistence of HIV-subtype A and obesity. Our aim was to evaluate the proportion of patients who could be eligible for switching to this strategy. one thousand seven hundred fifty-two patients were eligible. One hundred and forty-eight were excluded because of a detectable viral load. With regard to the exclusion criteria, 48 patients had coinfection with hepatitis B virus, and 744 had a history of previous virological failures. Of the 896 patients with at least one genotypic resistance test, 161 had one or more RAMs to rilpivirine and 3 had RAMs to cabotegravir. None of the patients presented the combination of obesity and the A viral subtype. Overall, 31.2% of the patients were ineligible for cabotegravir-rilpivirine, and the proportion increased to 47.3% when we considered only patients with all available information concerning resistance tests. Approximately half of our cohort of patients did not fulfill the criteria and even more patients were potentially ineligible for cabotegravir-rilpivirine due to the lack of genotypic resistance tests. Also, fertile women had to be excluded due to the lack of data about this combination during pregnancy and breastfeeding., (© 2022 Wiley Periodicals LLC.)
