Its use has been approved for the treatment of acute bacterial skin and skin structure infections (ABSSSI).Methods: We conducted a narrative review of the literature on the safety profile of dalbavancin. The bibliographic research was carried out on the PubMed database on 6 November 2020 by seeking combinations of the following keywords: dalbavancin, adverse effects, safety, drug interactions, and skin infections.Results: Five double-blind Phase 3 randomized clinical trials, 2 open-label randomized trials, and 4 retrospective studies were identified. No statistically significant differences were found between dalbavancin and comparators in the incidence of adverse events. Retrospective studies confirm the low incidence of adverse events.Conclusion: Dalbavancin is a therapeutic option that has demonstrated an excellent safety profile, also in relation to the other MRSA therapies available. Its use represents a cost-effective solution for the treatment of those patients with ABSSSI who would need hospitalization. One limitation of this study is that most of the available data are from Phase III clinical trials. Further real-life studies with a larger sample size are therefore needed to better assess the safety profile of the dalbavancin, especially to investigate the true incidence of rare adverse events.Keywords: dalbavancin, adverse events, safety, skin infections, ABSSSI

Abstract

The occurrence of COVID-19 pandemic had a significant negative effect on health care systems over the last year. Health care providers were forced to focus mainly on COVID-19 patients, neglecting in many cases equally important diseases, both acute and chronic. Therefore, also screening and diagnostic strategies for HIV could have been significantly impaired.This retrospective, multicenter, observational study aimed at assessing the number and characteristics of new HIV/AIDS diagnoses during COVID-19 pandemic in Italy and compared characteristics of people living with HIV at diagnosis between pre- and post-COVID-19 era (2019 vs 2020).Our results showed a significant reduction of HIV diagnoses during pandemic. By contrast, people living with HIV during pandemic were older and were diagnosed in earlier stage of disease (considering CD4+ T cell count) compared to those who were diagnosed the year before. Moreover, there was a significant decrease of new HIV diagnoses among men who have sex with men, probably for the impact of social distancing and restriction applied by the Italian Government. Late presentation incidence, if numbers in 2020 were lower than those in 2019, is still an issue.Routinely performing HIV testing in patients with suspected SARS-CoV-2 infection is identifying and linking to care underdiagnosed people living with HIV earlier. Thus, combined tests (HIV and SARS-CoV-2) should be implemented in patients with SARS-CoV-2 symptoms overlapping HIV's ones. Lastly, our results lastly showed how urgent implementation of a national policy for HIV screening is necessary.

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

Background: This study investigates the effects of the antimicrobial cationic peptide omiganan-alone and combined with the antibiotic imipenem-on colonic anastomosis healing in presence of intraperitoneal sepsis induced in a rodent model of cecal ligation and puncture (CLP). Methods: Forty male Wistar rats were divided into 5 groups of 8 animals. Group 1 (control group) underwent laparotomy and cecal mobilization and the next day received left colon anastomosis. In group 2 (CLP without treatment), group 3 (CLP + imipenem), group 4 (CLP + omiganan), and group 5 (CLP + omiganan + imipenem), the left colon anastomosis was performed the day after CLP. Imipenem and omiganan were administered by intraperitoneal injection immediately before anastomosis construction and subsequently at 24 h intervals until the 7th postoperative day, when rats were sacrificed. Anastomotic bursting pressure was measured in situ. Tissue samples were collected for determination of hydroxyproline content and histological characteristics. Results: Only rats receiving omiganan + imipenem displayed re-epithelialization, reduced neovascularization of granulation tissue, and a bursting pressure that was similar to that of controls. Omiganan-alone and combined with imipenem-was associated with a better control of inflammatory parameters than imipenem alone. In addition omiganan, like imipenem, counteracted the collagen depletion typical of sepsis. Conclusions: This experimental study demonstrates the efficacy of the new antimicrobial agent omiganan, alone and in combination with imipenem, in delaying the effects of intraperitoneal sepsis on colonic anastomosis healing and provides evidence of the value of omiganan as a therapeutic agent.

Abstract

OBJECTIVES: To define the impact of coinfection with hepatitis B virus (HBV) or hepatitis C virus (HCV) on viroimmunological response to raltegravir-based salvage regimens that also include new HIV inhibitors such as maraviroc, darunavir and etravirine. METHODS: We used data from a national observational study of patients starting raltegravir-based regimens to compare virological suppression and CD4 cell change from baseline in patients with and without concomitant HBV or HCV infection. RESULTS: Overall, 275 patients (107 coinfected and 168 non-coinfected) were evaluated. Coinfected patients were more commonly former intravenous drug users and had a longer history of HIV infection and higher baseline aminotransferase levels. Both HIV-RNA and CD4 response were similar in the two groups. Mean time to first HIV-RNA copy number

Abstract

OBJECTIVE: To investigate the efficacy of distinctin in a neutropenic mouse model of staphylococcal sepsis. DESIGN: Prospective, randomized, and controlled animal study. SETTING: Research laboratory in a University Hospital. SUBJECTS: BALB/c male mice. INTERVENTIONS: Mice were rendered neutropenic by injecting cyclophosphamide (200 mg/kg of body weight/day) on days -4 and -2 preinfection. Infection was induced at time 0 by intraperitoneal injection of 1 x 10(9) colony forming units of the staphylococcal strain. For each model, all animals were randomized to receive intravenous isotonic sodium chloride solution, 1 mg/kg distinctin, and 10 mg/kg imipenem, 10 mg/kg vancomycin, 10 mg/kg teicoplanin or 10 mg/kg linezolid alone, or combined with 1 mg/kg distinctin. MEASUREMENTS AND MAIN RESULTS: Lethality, bacterial growth in blood and peritoneum, spleen, liver, and mesenteric lymph nodes. RESULTS: All combined regimen showed lower lethality rates than singly treated-groups. Distinctin plus vancomycin or teicoplanin exerted the lowest lethality rate. All regimens were significantly superior to controls at reducing blood, spleen, peritoneum, liver and mesenteric lymph node complex bacterial burdens, whereas all combined treated groups were higher effective than singly treated groups. CONCLUSION: Our data indicate that distinctin alone or combined with other antibiotics may be useful in treating severe staphylococcal infections.

Abstract

The antimicrobial peptide distinctin consists of two peptide chains linked by a disulfide bridge; it presents a peculiar fold in water resulting from noncovalent dimerization of two heterodimeric molecules. To investigate the contribution of each peptide chain and the S-S bond to distinctin biochemical properties, different monomeric and homodimeric peptide analogues were synthesized and comparatively evaluated with respect to the native molecule. Our experiments demonstrate that the simultaneous occurrence of both peptide chains and the disulfide bond is essential for the formation of the quaternary structure of distinctin in aqueous media, able to resist protease action. In contrast, distinctin and monomeric and homodimeric analogues exhibited comparable antimicrobial activities, suggesting only a partial contribution of the S-S bond to peptide killing effectiveness. Relative bactericidal properties paralleled liposome permeabilization results, definitively demonstrating that microbial membranes are the main target of distinctin activity. Various biophysical experiments performed in membrane-mimicking media, before and after peptide addition, provided information about peptide secondary structure, lipid bilayer organization, and lipid-peptide orientation with respect to membrane surface. These data were instrumental in the generation of putative models of peptide-lipid supramolecular pore complexes.

Abstract

The ability of microorganisms to adhere to medical implants is a problem of high visibility and has been focused in numerous investigations. To assess the efficacy of distinctin and conventional antibiotics in the treatment of central venous catheter in vitro and in vivo studies were performed. The in vitro susceptibility assay was performed against S. aureus biofilms developed on 96-well polystyrene tissue culture plates. Efficacy studies were performed in a rat model of CVC infection. Twenty-four hours after implantation, the catheters were filled with distinctin. Thirty minutes later, rats were challenged via the CVC with S. aureus. Administration of antibiotics into the CVC at a concentration equal to the MBC for adherent cells, or at 1024 microg/mL began 24 h later. The killing activities of all antibiotics against adherent bacteria were at least four- to eightfold lower than against freely growing cells. When antibiotics were used in distinctin pretreated wells, they showed a significant increase of activity. The in vivo studies showed that when CVCs were pretreated with distinctin biofilm bacterial load was further decreased to 10(1) CFU/mL and bacteremia was not detected. Distinctin displays potential as an adjunctive agent to antibiotics in the treatment of CVC-related infections. (c) 2006 Wiley Periodicals, Inc.
