Aims The EURO-ENDO registry aimed to study the management and outcomes of patients with infective endocarditis (IE). Methods and results Prospective cohort of 3116 adult patients (2470 from Europe, 646 from non-ESC countries), admitted to 156 hospitals in 40 countries between January 2016 and March 2018 with a diagnosis of IE based on ESC 2015 diagnostic criteria. Clinical, biological, microbiological, and imaging [echocardiography, computed tomography (CT) scan, 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT)] data were collected. Infective endocarditis was native (NVE) in 1764 (56.6%) patients, prosthetic (PVIE) in 939 (30.1%), and device-related (CDRIE) in 308 (9.9%). Infective endocarditis was community-acquired in 2046 (65.66%) patients. Microorganisms involved were staphylococci in 1085 (44.1%) patients, oral streptococci in 304 (12.3%), enterococci in 390 (15.8%), and Streptococcus gallolyticus in 162 (6.6%). 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed in 518 (16.6%) patients and presented with cardiac uptake (major criterion) in 222 (42.9%) patients, with a better sensitivity in PVIE (66.8%) than in NVE (28.0%) and CDRIE (16.3%). Embolic events occurred in 20.6% of patients, and were significantly associated with tricuspid or pulmonary IE, presence of a vegetation and Staphylococcus aureus IE. According to ESC guidelines, cardiac surgery was indicated in 2160 (69.3%) patients, but finally performed in only 1596 (73.9%) of them. In-hospital death occurred in 532 (17.1%) patients and was more frequent in PVIE. Independent predictors of mortality were Charlson index, creatinine > 2 mg/dL, congestive heart failure, vegetation length > 10 mm, cerebral complications, abscess, and failure to undertake surgery when indicated. Conclusion Infective endocarditis is still a life-threatening disease with frequent lethal outcome despite profound changes in its clinical, microbiological, imaging, and therapeutic profiles.
Objectives Aim of our study was to describe the incidence and predictive factors of secondary infections in patients with COVID-19. Methods Cohort study on patients hospitalized with COVID-19 at IRCCS San Raffaele Hospital between February 25 th and April 6th, 2020 (NCT04318366). We considered secondary bloodstream (BSIs) or possible lower respiratory tract infections (pLRTIs) occurred after 48 hours since hospital admission until death or discharge. We calculated multivariable Fine-Gray models, to assess factors associated with risk of secondary infections. Results Among 731 patients, a secondary infection was diagnosed in 68 patients (9.3%): 58/731 patients (7.9%) had at least one BSI and 22/731 patients (3.0%) at least one pLRTI. Overall 28-day cumulative incidence was 16.4% (95% CI 12.4% - 21.0%). The majority of BSIs was due to gram-positive pathogens (76/106 isolates, 71.7%), specifically coagulase-negative staphylococci (53/76, 69.7%), while among gram-negatives (23/106, 21.7%) Acinetobacter baumanii (7/23, 30.4%) and Escherichia coli (5/23, 21.7%) predominated. pLRTIs were mainly caused by gram-negative pathogens (14/26, 53.8%). Eleven patients were diagnosed with putative invasive aspergillosis. At multivariable analysis, factors associated with secondary infections were low baseline lymphocyte count ( < 0.7 vs >0.7 per 10 9 /L: subdistribution hazard ratios (sdHRs) 1.93 [95% CI 1.11-3.35]), baseline PaO 2 /FiO 2 (per 100-points lower: sdHRs 1.56 [95% CI 1.21-2.04]), and intensive-care unit (ICU) admission in the first 48 hours (sdHR 2.51 [95% CI 1.04-6.05]). Conclusions Patients hospitalized with COVID-19 had a high incidence of secondary infections. At multivariable analysis, early need for ICU, respiratory failure, and severe lymphopenia, were identified as risk factors for secondary infections.
Type 2 diabetes mellitus is a growing problem in HIV population and a comparison with the general population may help screening and prevention. In this cross-sectional study the authors determined the prevalence of type 2 diabetes mellitus in 4,249 HIV-infected subjects attending the San Raffaele Infectious Diseases Department compared with 9,148 healthy controls recruited in 15 Italian regions, and identified risk factors associated with of type 2 diabetes mellitus. Type 2 diabetes mellitus was defined as reported diabetes, a fasting plasma glucose concentration ≥7.0 mmol/l, or current use of anti-diabetic medication. Prevalence of type 2 diabetes mellitus was higher in HIV-infected than healthy subjects (4.1 vs. 2.5 %; P < 0.0001). At multivariable analysis, HIV-infected subjects (odds ratio 1.70, 95 % CI, 1.12-2.51; P = 0.009), older age (P < 0.0001), higher BMI (P < 0.0001) and hypertension (P = 0.039) were associated with a higher risk of diabetes. Among HIV-infected patients, the risk of type 2 diabetes mellitus increased with older age (P < 0.0001), higher BMI (P = 0.003), higher triglycerides (P = 0.015) lower total cholesterol (P = 0.008), longer duration of HIV infection (P = 0.036) lower nadir CD4 (P = 0.027). Prevalence of type 2 diabetes mellitus in HIV-infected subjects was almost two-fold increased than healthy subjects and it was associated with the typical risk factors of the general population and also to longer duration of HIV infection and lower nadir CD4.
ObjectivesTo characterize osteoprotegerin (OPG) levels, bone remodelling and bone mineral density (BMD) in heavily pretreated HIV-infected patients on antiretroviral therapy, and to evaluate the clinical factors associated with bone density decline. MethodsHeavily pretreated (45 years) HIV-positive patients were enrolled in this cross-sectional, observational study, which was based on a total body bone densitometry examination and a comprehensive evaluation of bone and mineral parameters. ResultsSixty-eight patients (55 male and 13 female) with a median age of 41 years (range 25-60 years) were included in the study. Their antiretroviral treatment lasted for 82 months. On the basis of the World Health Organization criteria, nine patients (13.2%) were osteoporotic [T-scoreo À 2.5 standard deviation (SD)] and 19 patients (27.9%) were osteopenic (T-score between À 1 and À 2.5). The principal outcomes associated with the presence of a low BMD were high OPG and lysylpyridinoline/creatinine ratio ( There was an inverse correlation between T-scores and serum osteocalcin and alkaline phosphatase (AP) levels, on one hand, and Dpd, on the other. High AP and Dpd values were associated with relative risks of 4.1 [95% confidence interval (CI) 5 1.01-17.6] and 7.2 (95% CI 5 1.67-31.03), respectively, of a pathological T-score. Multivariate analysis revealed that the factors associated with the presence of osteopenia or osteoporosis were older age and lower body mass index. ConclusionsAbout 40% of our heavily pretreated subjects with advanced HIV infection had a low BMD, and 56% (24 of 44 patients) showed a high bone turnover rate with marked osteoclast activation. High OPG levels may protect against bone resorption.
To evaluate the safety and efficacy of 3 regimens of intermittent subcutaneous (sc) interleukin (IL)--2 in a phase 2 study, 61 antiviral drug-experienced human immunodeficiency virus (HIV)--positive patients were randomly assigned to one of the following study arms: antiretroviral therapy (ART) plus IL-2 (12 million IU [MIU] by continuous intravenous infusion, followed by 7.5 MIU twice a day, sc, every 8 weeks); ART plus IL-2 (7.5 MIU twice a day, sc, every 8 weeks); ART plus IL-2 (3 MIU twice a day, sc, every 4 weeks); or ART alone. A significant increase of circulating CD4 cells was observed in IL-2--treated subjects, compared with those given ART alone. Low doses of IL-2 were better tolerated. Despite the incomplete suppression of viral replication, IL-2 with ART did not increase either plasma viremia or cell-associated HIV DNA levels. Low doses of intermittent sc IL-2 induced a stable increase of peripheral CD4 cells that was indistinguishable from those associated with higher, less well-tolerated doses of IL-2.
The aim of this study was to evaluate the impact of early treatment with corticosteroids on SARS-CoV-2 clearance in hospitalized COVID-19 patients. Retrospective analysis on patients admitted to the San Raffaele Hospital (Milan, Italy) with moderate/severe COVID-19 and availability of at least two nasopharyngeal swabs. The primary outcome was the time to nasopharyngeal swab negativization. A multivariable Cox model was fitted to determine factors associated with nasopharyngeal swab negativization. Of 280 patients included, 59 (21.1%) patients were treated with steroids. Differences observed between steroid users and non-users included the proportion of patients with a baseline PaO2/FiO2 ≤ 200 mmHg (45.8% vs 34.4% in steroids and non-steroids users, respectively; p = 0.023) or ≤ 100 mmHg (16.9% vs 12.7%; p = 0.027), and length of hospitalization (20 vs 14 days; p < 0.001). Time to negativization of nasopharyngeal swabs was similar in steroid and non-steroid users (p = 0.985). According to multivariate analysis, SARS-CoV-2 clearance was associated with age ≤ 70 years, a shorter duration of symptoms at admission, a baseline PaO2/FiO2 > 200 mmHg, and a lymphocyte count at admission > 1.0 × 109/L. SARS-CoV-2 clearance was not associated with corticosteroid use. Our study shows that delayed SARS-CoV-2 clearance in moderate/severe COVID-19 is associated with older age and a more severe disease, but not with an early use of corticosteroids.
Few data are available regarding the 10‐year survival among subjects with HIV and cancer. The aim of this study was to evaluate the 10‐year survival of HIV‐infected subjects with AIDS‐defining malignancies (ADM) or non‐AIDS‐defining malignancies (NADM). This was a single center, retrospective, observational study of subjects with HIV infection and a subsequent cancer diagnosis; the data were collected from January 1991 to April 2010. Malignancies were divided into ADM or NADM on the basis of the Centre of Diseases Control‐1993 classification. Survival curves were estimated using Kaplan–Meyer method and compared by the log‐rank test. Six hundred and fifteen (9.5%) of the 6,495 subjects recorded in the San Raffaele Infectious Diseases Database developed a malignancy: 431 (70%) an ADM and 184 (30%) a NADM. In the case of ADM, survival was more favorable when cancer was diagnosed during post‐highly active antiretroviral therapy (HAART) era (10‐year survival: 43.2% ± 4.4%) than when diagnosed during the pre‐HAART era (10‐year survival: 16.4% ± 2.7%; log‐rank test: p < 0.001). The same was true in the case of NADM (10‐year survival: 44.7% ± 5.5% vs. 33.3 ± 9.6%; log‐rank test: p = 0.03). An evaluation of survival probability by cancer type showed higher survival rates during the post‐HAART era in the case of non‐Hodgkin lymphoma (10‐year survival: 42.1% ± 5.3% vs. 11.4% ± 3.3%; log‐rank test: p = <0.001), Kaposi's sarcoma (10‐year survival: 44.0% ± 8.4% vs. 23.5% ± 3.9%; log‐rank test: p < 0.001) and Hodgkin's disease (10‐year survival: 49.5% ± 14.5% vs. 40.0% ± 12.7%; log‐rank test: p = 0.005). Despite the better cancer prognosis during the post‐HAART era, the 10‐year survival of HIV‐infected subjects with an ADM or NADM is poor.
BackgroundRhodococcus equi (R.equi) is an acid fast, GRAM + coccobacillus, which is widespread in the soil and causes pulmonary and extrapulmonary infections in immunocompromised people. In the context of HIV infection, R.equi infection (rhodococcosis) is regarded as an opportunistic disease, and its outcome is influenced by highly active antiretroviral therapy (HAART).Case presentationWe report two cases of HIV-related rhodococcosis that disseminated despite suppressive HAART and anti-rhodococcal treatment; in both cases there was no immunological recovery, with CD4+ cells count below 200/μL. In the first case, pulmonary rhodococcosis presented 6 months after initiation of HAART, and was followed by an extracerebral intracranial and a cerebral rhodococcal abscess 1 and 8 months, respectively, after onset of pulmonary infection. The second case was characterized by a protracted course with spread of infection to various organs, including subcutaneous tissue, skin, colon and other intra-abdominal tissues, and central nervous system; the spread started 4 years after clinical resolution of a first pulmonary manifestation and progressed over a period of 2 years.ConclusionsOur report highlights the importance of an effective immune recovery, despite fully suppressive HAART, along with anti-rhodococcal therapy, in order to clear rhodococcal infection.
