RESUMO
PURPOSE: Vancomycin-resistant enterococci (VRE) are a leading cause of hospital-acquired infections with limited therapeutic options. Combination of at least two antimicrobials is a possible strategy to obtain rapid and sustained bactericidal effects and overcome the emergence of resistance. We revised the literature on linezolid synergistic properties from in vitro studies to assess its activity in combination with molecules belonging to other antibiotic classes against Enterococcus spp. METHODS: We performed a systematic review of the literature from three peer-reviewed databases including papers evaluating linezolid synergistic properties in vitro against Enterococcus spp. isolates. RESULTS: We included 206 Enterococcus spp. isolates (92 E. faecalis, 90 E. faecium, 2 E. gallinarum, 3 E. casseliflavus, 19 Enterococcus spp.) from 24 studies. When an isolate was tested with different combinations, each combination was considered independently for further analysis. The most frequent interaction was indifferent effect (247/343, 72% of total interactions). The highest synergism rates were observed when linezolid was tested in combination with rifampin (10/49, 20.4% of interactions) and fosfomycin (16/84, 19.0%, of interactions). Antagonistic effect accounted for 7/343 (2.0%) of total interactions. CONCLUSION: Our study reported overall limited synergistic in vitro properties of linezolid with other antibiotics when tested against Enterococcus spp. The clinical choice of linezolid in combination with other antibiotics should be guided by reasoned empiric therapy in the suspicion of a polymicrobial infection or targeted therapy on microbiological results, rather than on an intended synergistic effect of the linezolid-based combination.

PURPOSE: Real-world experience with meropenem/vaborbactam (M/V) is limited. Our aim is to report a clinical experience of M/V in the treatment of resistant Gram-negative bacilli. METHODS: This is a prospective observational study including patients hospitalized in the University Hospital of Pisa (March 2021-Jan 2023) with infections by both extended-spectrum ß-lactamases (ESBL)-producing Enterobacterales and carbapenem-resistant Klebsiella pneumoniae (Kp) treated with M/V. The primary outcome measure was clinical success, defined as a composite of survival, resolution of signs and symptoms and absence of microbiological failure at day 30 from infection onset. A multivariable regression analysis was performed to identify factors associated with clinical failure. Odds ratio (OR) with 95% confidence intervals (CI) was calculated. RESULTS: A total of 104 patients who received M/V were included: 24/104 (23.1%) infections were caused by ESBL non-hypervirulent Enterobacterales, 17/104 (16.3%) by ESBL-producing hypervirulent Klebsiella pneumoniae (hvKp) and 63/104 (60.6%) by CRE. The most common infections were bloodstream infections, followed by urinary tract infections, hospital-acquired pneumonia, intra-abdominal infections and others. Septic shock occurred in 16/104 (15.4%) patients. Clinical success was achieved in 77% of patients, and 30-day mortality rate was 15.4%. In patients with KPC-producing Kp infections, clinical success and 30-day mortality rates were 82% and 11.5%, respectively. On multivariable analysis, SOFA score (OR 1.32, 95% CI 1.02-1.7, p=0.032) was independently associated with clinical failure, while source control (OR 0.16, 95% CI 0.03-0.89, p=0.036) was protective. CONCLUSIONS: M/V is a promising therapeutic option against infections caused by difficult-to-treat ESBL-producing Enterobacterales and CR-Kp.
RESUMO
Tuberculosis (TB) diagnosis and management in special populations remain challenging. Data about TB and transgender individuals is scarce, and strategies aimed at reducing the TB burden in this at-risk group are needed. We conducted an observational monocentric study from a national reference center for TB, including transgender individuals with active TB in a low-TB burden country (Italy), over 34 years (1990-2023). Sixty-six transgender males and two transgender females (median age 30 years, interquartile range 26-38 years, 65 migrants) were included. Most patients (38/66, 57.6%) lived in poor social conditions. 65.2% (43/66) of patients were people living with HIV. Multidrug- and rifampicin-resistant tuberculosis and isoniazid-resistant TB were diagnosed in five (7.6%) and three (4.5%) patients, respectively. The overall treatment success rate was 72.7% (48/66 patients), with differences observed according to social conditions. Our study highlights the need for a tailored approach to increase treatment success in this at-risk population.
RESUMO
BACKGROUND: Metallo-ß-lactamases (MBL)-producing Enterobacterales are increasing worldwide. Our aim was to describe clinical features, treatments and outcomes of infections by MBL-Enterobacterales. METHODS: Prospective observational study conducted in the Pisa University Hospital (Jan 2019-Oct 2022) including patients with MBL-producing Enterobacterales infections. The primary outcome measure was 30-day mortality. A multivariable Cox regression analysis was performed to identify factors associated with 30-day mortality. Adjusted hazard ratio (aHR) (95% confidence intervals, CI) were calculated. RESULTS: 343 patients were included: 15 VIM- and 328 NDM-producing Enterobacterales infections. Overall, 199 (58%) were bloodstream infections, 60 (17.5%) hospital-acquired/ventilator-associated pneumonias, 60 (17.5%) complicated urinary tract infections, 13 (3.8%) intra-abdominal infections, 11 (3.2%) skin and soft tissue infections. Thirty-day mortality was 29.7%. Thirty-two patients did not receive in vitro active antibiotic therapy, 215/343 (62.7%) received ceftazidime-avibactam (CZA) plus aztreonam (ATM), 33/343 (9.6%) cefiderocol-containing regimens, 26/343 (7.6%) colistin-containing regimens and 37 (10.8%) other active antibiotics. On multivariable analysis, septic shock (aHR 3.57, 95% CI 2.05-6.23, p<0.001) and age (aHR 1.05, 95% CI 1.03-1.08, p<0.001) were independently associated with 30-day mortality, while in vitro active antibiotic therapy within 48 hours from infection (aHR 0.48, 95% CI 0.26-0.8, p=0.007) and source control (aHR 0.43, 95% CI 0.26-0.72, p=0.001) were protective factors. Sensitivity analysis showed that CZA plus ATM compared to colistin was independently associated with reduced 30-day mortality (aHR 0.39, 95% CI 0.18-0.86, p=0.019). Propensity score analyses confirmed these findings. CONCLUSIONS: MBL-CRE infections are associated with high 30-day mortality rates. Patients with MBL-producing Enterobacterales infections should received early active antibiotic therapy.
RESUMO
INTRODUCTION: The effect of remdesivir on COVID-19 mortality remains conflicting. Elderly individuals are at risk for poor COVID-19 outcomes. We aimed to assess the effect of remdesivir on COVID-19 mortality among elderly individuals, using real-world data. METHODS: Retrospective multinational cohort of individuals aged ≥65 years, hospitalized with COVID-19 in six medical centres between January 2020 and May 2021. Associations with in-hospital mortality were evaluated using a multivariable logistic regression model with propensity score adjustment for remdesivir therapy and while implementing generalized estimating equations to control for centre effect. Sensitivity analysis was performed by stratification according to the degree of respiratory support. RESULTS: Of 3010 individuals included, 2788 individuals required either oxygen supplementation or non-invasive/invasive mechanical ventilation, 489 (16%) were treated with remdesivir, and 836 (28%) died. Median age was 77 (IQR 70-84) years and 42% were women. Remdesivir was the only therapeutic intervention associated with decreased mortality [adjusted OR (aOR) 0.49, 95% CI 0.37-0.66, Pâ<â0.001]. This protective effect was shown for individuals requiring oxygen support and non-invasive mechanical ventilation, while no association was found among individuals necessitating invasive mechanical ventilation.Risk factors for mortality included invasive ventilation (aOR 5.18, 95% CI 2.46-10.91, Pâ<â0.001), higher serum creatinine (aOR 1.25, 95% CI 1.09-1.43, Pâ=â0.001) and dyspnoea (aOR 1.40, 95% CI 1.07-1.84, Pâ=â0.015) on presentation, and other non-modifiable factors, such as comorbidities. CONCLUSIONS: Among elderly individuals hospitalized with COVID-19, remdesivir carries survival benefit for those with moderate to severe disease. Its role among individuals with critical illness should be further assessed.

INTRODUCTION: Daptomycin is a bactericidal lipopeptide antibiotic approved for the treatment of systemic infections (i.e. skin and soft tissue infections, bloodstream infections, infective endocarditis) caused by Gram-positive cocci. It is often prescribed in association with a partner drug to increase its bactericidal effect and to prevent the emergence of resistant strains during treatment; however, its synergistic properties are still under evaluation. METHODS: We performed a systematic review to offer clinicians an updated overview of daptomycin synergistic properties from in vitro and in vivo studies. Moreover, we reported all in vitro and in vivo data evaluating daptomycin in combination with other antibiotic agents, subdivided by antibiotic classes, and a summary graph presenting the most favourable combinations at a glance. RESULTS: A total of 92 studies and 1087 isolates (723 Staphylococcus aureus, 68 Staphylococcus epidermidis, 179 Enterococcus faecium, 105 Enterococcus faecalis, 12 Enterococcus durans) were included. Synergism accounted for 30.9% of total interactions, while indifferent effect was the most frequently observed interaction (41.9%). Antagonistic effect accounted for 0.7% of total interactions. The highest synergistic rates against S. aureus were observed with daptomycin in combination with fosfomycin (55.6%). For S. epidermidis and Enterococcus spp., the most effective combinations were daptomycin plus ceftobiprole (50%) and daptomycin plus fosfomycin (63.6%) or rifampicin (62.8%), respectively. FUTURE PERSPECTIVES: We believe this systematic review could be useful for the future updates of guidelines on systemic infections where daptomycin plays a key role.

PURPOSE: To investigate the effects of different antibiotic prophylaxis regimens in patients with diabetes mellitus (DM) candidates to trans-rectal ultrasound-guided prostate biopsy (TRUSPB). METHODS: 143 outpatients with DM who underwent TRUSPB during the period 2018-2020 were selected from a cohort of 1150 patients in 3 different institutions. Exclusion criteria were allergies, concomitant anti-platelet therapies and uncontrolled DM. Different antibiotic prophylaxis regimens were adopted. Bacterial resistance levels to fluoroquinolones into the different communities were also collected. Univariable and multivariable binomial logistic regression analyses were used to assess the odds ratio (OR) with 95% confidence intervals (CIs) testing the risk of infective complications' occurrence after adjusting for clinical covariates. RESULTS: Overall, DM patients were significantly associated with infective complications' occurrence (p < 0.001). No differences on the event of sepsis were found between diabetic and non-diabetic patients. Clinically relevant infections with fever > 37 °C were found in 9.1% and 1.5% (p < 0.001) in diabetic and non-diabetic patients, respectively. Trimethoprim-sulphametoxazole and fluoroquinolones were six times more efficient than Cefixime in non-diabetic patients. Fluoroquinolones confirmed the same effect in diabetic patients although the level of resistance in the period of study decreased only from 56 to 46%. CONCLUSION: Fluoroquinolones were active in antibiotic prophylaxis of diabetic patients who had undergone to TRUSPB independently from the level of bacterial resistance found in the community. These results conflict with the recent European warning and support the Japanese and American guidelines on the topic.

Patients with specific hematological malignancies (HM) are at increased risk for severe disease and death from infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In healthy subjects, vaccination against SARS-CoV-2 has been demonstrated to be highly effective in disease prevention; however, immunocompromised patients were largely excluded from vaccine randomized controlled trials. In this review, we overview available non-randomized studies addressing effectiveness and safety of several coronavirus disease 2019 (COVID-19) vaccines in patients with HM. Overall, COVID-19 vaccines are safe in patients with HM, with adverse events similar to those in the general population. Though serology testing is not recommended as a test to evaluate vaccine effectiveness, a correlation between higher antibody levels and protection against infection has been reported. Studies evaluating humoral response to COVID-19 vaccine in HM patients demonstrate low immunogenicity, mainly in patients with lymphoproliferative disorders, as well as with certain drugs, including mainly anti-CD20 antibodies, Bruton tyrosine kinase inhibitors, and also ruxolitinib and venetoclax. Seropositivity rates of patients with non-Hodgkin lymphoma and chronic lymphocytic leukemia following mRNA vaccination reach 40%-50%. T-cell responses to vaccination are also impaired among these patients. Better humoral response rates are reported in multiple myeloma patients and hematopoietic stem-cell transplant, reaching â¼75%-80%, but not in patients following chimeric antigen receptor T-cell therapy. Patients with chronic myeloid leukemia and myeloproliferative diseases have high response rate to vaccination. Third mRNA vaccine dose is currently recommended to all HM patients. Alternative approaches for vaccination and prevention in patients unable to mount an immune response following full vaccination are provided in the review.

Diagnosis and management of infectious diseases (ID) at the emergency department (ED) are challenging due to the peculiar setting and the available diagnostic tools. The involvement of an ID consultant has been described to improve clinical outcomes and antimicrobial stewardship (AMS) programs. An online survey was sent to 100 Italian Departments of Infectious Diseases affiliated with the Italian Society of Infectious Diseases and Tropical Medicine (SIMIT). The primary objective of our study was to describe the characteristics of ID services in Italian EDs to identify possible challenges and shortcomings and provide tips to improve the management of patients. Secondary objectives included the evaluation of diagnostic capability and the management of patients with suspected or confirmed ID. Seventy-six out of the 100 SIMIT centers, 32 (42.1%) of which were teaching hospitals, answered the survey. In 62 (82.7%) centers, consultations were performed by the IDs specialist on call. In 29 (38.2%) centers, there was a formal AMS program, and 32 (42.7%) had protocols for antibiotic use in the ED. Microbiological tests to be performed before starting antibiotic treatment in the ED were clearly defined in 44 (57.9%) hospitals. This survey highlighted several challenges in the current organization of ID consultations in Italian EDs.

PURPOSE: The recent rise in migration from Africa through the Mediterranean basin into Europe has resulted in an increased incidence of uncommon diseases such as schistosomiasis and genito-urinary tuberculosis, which were previously largely unknown in this region. This study aimed to evaluate the insight of European urologists into diagnosing and managing these disease conditions and to determine whether they were adequately prepared to deal with the changing disease spectrum in their countries. METHODS: A survey including specific questions about the diagnosis and management of 'tropical' urological diseases was distributed among urologists working in Europe and Africa. Multivariate logistic regression models were performed to detect the continent (African or European) effect on knowledge of and insight into tropical urological diseases. RESULTS: A total of 312 surveys were administered. African and European respondents accounted for 109 (36.09%) and 193 (63.91%) respondents, respectively. The multivariate logistic regression analysis demonstrated a significant deficiency in the knowledge of tropical urological diseases in the European cohort compared with the African cohort (p < 0.05). Moreover, in the European cohort, markedly superior knowledge of tropical urological diseases was observed for respondents who had previously worked in a developing country. CONCLUSIONS: Though European urologists are not required to have the same insight as African urologists, they showed a very unsatisfactory knowledge of tropical urological diseases. The experience of working in a developing country could improve the knowledge of European urologists regarding tropical urological diseases.

Mycobacterium chimaera is a non-tuberculous mycobacterium belonging to the Mycobacterium avium complex, described for the first time in 2004. It acts as an opportunistic pathogen, with infections, usually respiratory illnesses, occurring more frequently in immunocompromised patients or in patients with underlying respiratory diseases. During the last decade Mycobacterium chimaera disseminated infections following cardiothoracic surgery, especially open-heart surgery, have been increasingly reported worldwide. From a pathogenic standpoint, Mycobacterium chimaera is acquired during cardiopulmonary bypass via bioaerosols emitted from contaminated heater-cooler units water systems. Due to non-specific symptoms and long latency, postoperative Mycobacterium chimaera infections may not be promptly diagnosed and treated, and may become life-threatening. The indication for revision surgery needs to be carefully evaluated on a case-by-case basis, and antibiotic therapy should be based on drug susceptibility testing results. Our review aims to provide an updated account of microbiological characteristics, clinical presentation, diagnosis, and management of Mycobacterium chimaera infections, with a special focus on those developing after cardiothoracic surgery.

BACKGROUND: Since 2014, the migrant population residing in Europe has dramatically increased. Migrants' unmet health needs represent a barrier to integration and should be promptly addressed, without stigma, in order to favour resettlement. METHODS: All-cause of admissions in the migrant population at the Infectious Disease Clinic of Policlinico San Martino Hospital in Genoa between 2015 and 2017 were analysed. Patients were classified by duration of residence in Italy according to the Recommendation on Statistics of International Migration, cause of hospitalization, and region of origin. All data were evaluated with SPSS Statistics. RESULTS: Two hundred thirty-five people were admitted, 86 (36.5%) of them residing in Italy for less than 1 year. Except for a significant increase in migrants from Africa, there was no change considering the area of origin, hospitalization reason or by comparing residency in Italy for more or less than 1 year. A considerable number of hospitalizations were related to non-communicable pathologies and latent tuberculosis infection. Residents in Italy for less than 1 year or with active tuberculosis had prolonged hospitalizations, while HIV-infected had shorter hospital stays. CONCLUSIONS: No difference in terms of diagnosis were found between migrants with longer or shorter period of residence in Italy. Adequate outpatient services for the management of communicable diseases could significantly reduce the length of hospitalizations in the migrant population.

We describe the outcome of a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) IgG/IgM rapid test, and discuss the potential suitability of antibody testing. Retrospective single cohort study on patients with suspected Coronavirus Disease 2019 (COVID-19) and asymptomatic Healthcare Workers, enrolled from March to April 2020. Subjects had quantitative PCR (qPCR) test for detection of SARS-CoV-2 via nasal swab and serological testing using the COVID-19 IgG/ IgM Rapid Test (PRIMA Lab SA) immunochromatographic assay. Some subjects underwent chemiluminescence immunoassay (CLIA) after rapid test. The aim of the study was to analyse the proportion of those who developed a positive IgM/IgG response for SARS-CoV-2. The correspondence between the results from rapid testing and CLIA, when available, was evaluated. 97 subjects underwent qPCR for SARS-CoV-2 through nasal swab, which resulted positive in 40/43 (93.0%) of symptomatic patients, 2/40 (5%) of asymptomatic HCW, in no subjects with suspected COVID- 19 (clinical and radiological findings) then excluded by repeated nasal swabs and alternative diagnosis (COVID-19-negative patients, CNPs), and in 6/6 (100%) of patients with confirmed diagnosis and negative follow-up nasal swabs (COVID-19-recovered patients, CRPs). IgM resulted positive in 8/43 (18.6%) of symptomatic patients and in 1/6 (16.7%) of CRPs. IgG resulted positive in 36/43 (83.7%) of symptomatic patients, 2/40 (5%) of HCW, and in 1/8 (12.5%) and 6/6 (100%) of CNPs and CRPs, respectively. A comparison between an IgG/IgM Rapid Test and a following CLIA test showed consistency in negative results in 25/28 of HCW and 8/8 of CNPs tested. Our preliminary data support the role of IgG/IgM Rapid Test (PRIMA Lab SA) immunochromatographic assay as a point-of-care test that may complement molecular tests in the screening of SARS-CoV-2 carriers. The test may gain particular relevance in shortening the time needed to refer patients to a COVID or non-COVID Hospital area and to achieve diagnosis in patients with persistently negative nasal swabs.

Inflammatory Bowel Diseases (IBD) and intestinal tuberculosis (ITB) frequently share similar clinical, radiological, endoscopic and histologic features. The misdiagnosis of IBD can lead to worsening of ITB course, eventually with dissemination of Mycobacterium tuberculosis (MTB) due to immunosuppressive treatment. We herein report a challenging diagnosis of ITB, progressed from localized to disseminated, in a pregnant woman previously misdiagnosed with Crohn' disease (CD) on prolonged steroid treatment. Furthermore, we focus on three main issues: 1) the need for tuberculosis (TB) screening in pregnant women and in patients coming from TB endemic countries; 2) the effect of prolonged steroid treatment in misdiagnosed TB, particularly on its histological pattern; 3) the optimum clinical management of ITB.

BACKGROUND: The increased incidence of drug-resistant TB is a major challenge for effective TB control. Limited therapeutic options and poor treatment outcomes of DR-TB may increase drug-resistance rates. The objective of the study is to retrospectively compare MDR-TB and pre-XDR-TB treatment regimens and outcomes in two large TB reference centres in Italy from January 2000 to January 2015. METHODS: A retrospective, multicentre study was conducted at the Regional TB Reference Centre Villa Marelli Institute (Milan) and at the Reference Center for MDR-TB and HIV-TB, Eugenio Morelli Hospital (Sondalo). The supra-national Reference Laboratory in Milan performed DST. Inclusion criteria were: age ≥ 18 and culture-confirmed diagnosis of MDR- or pre-XDR TB. Chi-square or Fisher exact test was used to detect differences in the comparison between treatment outcomes, therapeutic regimens, and drug-resistances. Computations were performed with STATA 15. RESULTS: A total of 134 patients were selected. Median (IQR) age at admission was 33 (26-41) years and 90 patients (67.2%) were male. Pulmonary TB was diagnosed in 124 (92.5%) patients. MDR- and pre-XDR-TB cases were 91 (67.9%) and 43 (32.1%), respectively. The WHO shorter MDR-TB regimen could have been prescribed in 16/84 (19.1%) patients. Treatment success was not statistically different between MDR- and pre-XDR-TB (81.3% VS. 81.4%; P = 0.99). Mortality in MDR-TB and pre-XDR-TB groups was 4.4 and 9.3%, respectively (P = 0.2). Median duration of treatment was 18 months and a total of 110 different regimens were administered. Exposure to linezolid, meropenem, and amikacin was associated with a better outcome in both groups (P = 0.001, P < 0.001, and P = 0.004, respectively). CONCLUSIONS: Tailored treatment regimens based on DST results can achieve successful outcomes in patients with pre-XDR-TB.

INTRODUCTION: Leprosy is nowaday increasingly encountered in non-endemic countries. Nerve involvement is common. Swelling of the nerves may lead to entrapment neuropathy causing pain and neurological deficits. Delay in diagnosis and treatment may lead to loss of chance of improvement. Surgical decompression in conjunction with medical therapy allows relief of symptoms. METHODS: We present a retrospective series of 21 patients surgically treated in our center for leprosy entrapment neuropathy. We report presentation, treatment, and outcome at follow-up including a brief literature review. RESULTS: Twenty-one patients were treated for nerve entrapments in four different anatomical districts. We reported good clinical outcomes mainly in motor deficits but also in improvement of sensitive deficits and pain symptoms. We did not experience surgical complications. DISCUSSION: Although there is a lack of high-quality prospective studies comparing medical and surgical treatment of leprosy neuropathy, benefits of surgery are widely reported in series and case reports from endemic countries. There is scant literature from low-incidence countries even if leprosy incidence is nowaday increasing in these countries and will likelihood further increase in the future. Our results are in line with the literature presenting good outcomes after surgery. CONCLUSION: We believe that a precise knowledge of the pathology and its management is crucial also for physicians who work in low-incidence countries to maximize healing chances with timely diagnosis and treatment.

BACKGROUND: Mycobacterium tuberculosis is responsible for high morbidity and mortality in immune-compromised hosts. CASE PRESENTATION: We present a rare case of cutaneous tuberculosis after orthotopic liver transplantation without involvement of any other organs. CONCLUSION: TB risk-factors assessment, careful LTBI screening and treatment according to national guidelines, as well as a reduction in missed opportunity for prevention are necessary to avoid MTB related disease in fragile patients.
