Migrant and Italian HIV-infected patients (n = 5773) enrolled in the ICONA cohort in 2004-2014 were compared for disparities in access to an initial antiretroviral regimen and/or risk of virologic failure (VF), and determinants of failure were evaluated. Variables associated with initiating antiretroviral therapy (ART) were analysed. Primary endpoint was time to failure after at least 6 months of ART and was defined as: VF, first of two consecutive virus loads (VL) >200 copies/mL; treatment discontinuation (TD) for any reason; and treatment failure as confirmed VL >200 copies/mL or TD. A Poisson multivariable analysis was performed to control for confounders. Migrants presented significantly lower CD4 counts and more frequent AIDS events at baseline. When adjusting for baseline confounders, migrants presented a lower likelihood to begin ART (odds ratio 0.80, 95% confidence interval (CI) 0.67-0.95, p 0.012). After initiating ART, the incidence VF rate was 6.4 per 100 person-years (95% CI 4.8-8.5) in migrants and 2.7 in natives (95% CI 2.2-3.3). Multivariable analysis confirmed that migrants had a higher risk of VF (incidence rate ratio 1.90, 95% CI 1.25-2.91, p 0.003) and treatment failure (incidence rate ratio 1.16, 95% CI 1.01-1.33, p 0.031), with no differences for TD. Among migrants, variables associated with VF were age, unemployment and use of a boosted protease inhibitor-based regimen versus nonnucleoside reverse transcriptase inhibitors. Despite the use of more potent and safer drugs in the last 10 years, and even in a universal health care setting, migrants living with HIV still present barriers to initiating ART and an increased risk of VF compared to natives.

performing serology for the viral infections associated with cutaneous manifestations, for example parvovirus B19 and enterovirus. Most of them reported itching and burning sensation. Only two of them referred pain. They were variably symptomatic for the respiratory tract, but none of them had such a severe lung involvement as to require intubation. One of them was completely asymptomatic, and only the acral vascular manifestation led us the suspicion of coronavirus infection. In six of the patients showing exanthematic rashes, a punch biopsy for histological examination was obtained (Fig. 1F), showing features of perivascular dermatitis and vasculitis, which are compatible with that of a viral exanthem. It is known that exanthematic rashes can occur during viral infection. 4 We can say that erythematous rashes during coronavirus infections may have the same origin as the other viral rashes. 5 Instead, the vasculitic eruptions could be due to the vascular changes observed in these patients. Degeneration of the endothelium and vascular damages, including both formation of thrombus and congestion in small vessels, were observed in organs other than the lung in autopsies from skin. Indeed, while the 2019-nCoV is mainly distributed in the lung, the damage caused by the infection also involves the vessels, with the possibility of ischaemic and embolic damages. 6 The clinical patterns of the rashes described in COVID-19 patients till now include urticaria, acral ischaemia, morbilliform, livedo reticularis, vesicular and petechial. 5,7-9 As regards, the histological patterns, perivascular dermatitis and transient acantholytic dermatosis are those described till now. 10. We are presenting this paper to share our cases of skin involvement during the coronavirus disease. Undoubtedly, no certain association can be established between COVID-19 and skin eruptions, and further studies are needed.

Background Currently, no data are available on the burden of morbidity and mortality in people living with HIV-1 (PLWH) harboring a 4-class drug resistant (4DR) virus (NRTI, NNRTI, PI, INSTI). The study aimed to assess the incidence of clinical events or death in this population. Methods Cohort study on PLWH, from the PRESTIGIO Registry, with a documented 4DR virus.The burden of disease was defined as the occurrence of any new event including AIDS-defining event (ADE) or non-AIDS-defining event (NADE) or death for any cause, after 4DR evidence (baseline).Cox regression models evaluated factors associated with the risk of new clinical events/death. Results Among 148 PLWH followed for a median of 47 months (IQR=32-84) since 4DR evidence, 38 PLWH had 62 new events or died for any cause [incidence rate, 9.12/100-PYFU (95%CI=6.85-11.39)]: 12 deaths (6 AIDS-related and 6 non-AIDS-related), 18 ADE, 32 NADE; 20 of the 38 NADE (45%) of the incident clinical events were malignancies. The 4-year cumulative incidence of death was 6% (95%CI=3%-13%) and that of ≥1 event or death was 22% (95%CI=16%-31%). A higher risk of new clinical events/death was more likely in PLWH with previous clinical events (aHR=2.67, 95%CI=1.07-6.67) and marginally associated with lower baseline CD4+/CD8+ ratio (aHR=0.82, 95%CI=0.65-1.02). Conclusions PLWH harbouring 4DR have a high burden of disease with a worrying incidence of malignancies, strongly advising for close prevention and monitoring interventions as well as access to innovative therapeutic strategies, especially in people with a history of clinical events and low CD4+/CD8+ ratio.

Objectives Our aim was to investigate the durability of different initial regimens in patients starting ART with CD4+ counts <200 cells/mm3 and HIV-RNA >5 log10 copies/mL. Methods This was a retrospective study of HIV-infected patients prospectively followed in the ICONA cohort. Those who started ART with boosted protease inhibitors (bPIs), NNRTIs or integrase strand transfer inhibitors (InSTIs), with CD4+ <200 cells/mm3 and HIV-RNA >5 log10 copies/mL, were included. The primary endpoint was treatment failure (TF), a composite endpoint defined as virological failure (VF, first of two consecutive HIV-RNA >50 copies/mL after 6 months of treatment), discontinuation of class of the anchor drug or death. Independent associations were investigated by Poisson regression analysis in a model including age, gender, mode of HIV transmission, CDC stage, HCV and HBV co-infection, pre-treatment HIV-RNA, CD4+ count and CD4+/CD8+ ratio, ongoing opportunistic disease, fibrosis FIB-4 index, estimated glomerular filtration rate, haemoglobin, platelets, neutrophils, calendar year of ART initiation, anchor drug class (treatment group) and nucleos(t)ide backbone. Results A total of 1195 patients fulfilled the inclusion criteria: 696 started ART with a bPI, 315 with an InSTI and 184 with an NNRTI. During 2759 person-years of follow up, 642 patients experienced TF. Starting ART with bPIs [adjusted incidence rate ratio (aIRR) (95% CI) 1.62 (1.29–2.03) versus starting with NNRTIs; P < 0.001] and starting ART with InSTIs [aIRR (95% CI) 0.68 (0.48–0.96) versus starting with NNRTIs; P = 0.03] were independently associated with TF. Conclusions In patients starting ART with <200 CD4+ cells/mm3 and >5 log10 HIV-RNA copies/mL, the durability of regimens based on InSTIs was longer than that of NNRTI- and bPI-based regimens.
