ABSTRACT
BACKGROUND: Migrants, mainly undocumented and low-income refugees, are at high risk of hepatitis C virus (HCV) infection, but are a difficult-to-reach and to-treat population. The aim of the study was to evaluate the effectiveness of a test and treat model with direct-acting antiviral for HCV infection in these migrants coming from low-income and living in southern Italy. METHODS: A prospective, multicenter, collaborative study based on a four-phase-program (educational counseling, screening, linkage-to-care and treatment) was designed in southern Italy; the study started in June 2018, was stopped in February 2020 because of the outbreak of SARS-CoV2 infection in Italy and was resumed in February 2021 until November 2021. After educational counseling on infectious diseases that are transmitted through blood or sexually pseudonymized HCV screening was offered to all undocumented migrants and low-income refugees observed at one of the 1st level clinical centers. The HCV-RNA-positive subjects were referred to one of the 3rd level units of Infectious Diseases (ID) and treated with a 12-week course of sofosbuvir-velpatasvir and observed for 12 weeks after the end of direct antiviral agents (DAA) treatment. STATISTICAL ANALYSIS: For the descriptive analysis, the categorical variables were reported as absolute numbers and relative frequencies. Continuous variables were summarized as mean and standard deviation (SD) if normally distributed, or as a median and interquartile range (IQR) if not normally distributed. We used Pearson chi-square or Fisher's exact test for categorical variables and Student's t test or Mann-Whitney test for continuous variables. A P value < 0.05 was considered to be statistically significant. Analyses were performed with SPSS 21.0. RESULTS: Of the 3501migrants observed in the study period, 3417 (97.6%) agreed to be screened; 185 (4.7%) were anti-HCV-positive and, of these, 53 (28.6%) were HCV-RNA-positive. Of these 53 subjects, 48 (90.5%) were referred to an ID unit and started DAA treatment. The HCV-RNA-positive-subjects were older [median 36 years (IQR: 32-21) vs 27.19 (IQR: 30.5-19.25); P = 0.001], and less frequently males [35 (66.03 %) vs 119 (90.1%), P < 0 .0001] than seronegative participants. They more frequently came from Eastern Europe (70.8%) stayed longer in Italy [months of stay in Italy, mean ± SD: 51.02 ± 52.84 vs 25.7 ± 42.65, P = 0.001], and had more years of schooling [years of schooling, mean ± SD: 9.61±2.81 vs 7.10 ± 4, P = 0.0001]. HCV-RNA-positive-subjects less frequently reported piercing, tattoos and tribal scars as risk factors (23.6%). Of these 48 HCV RNA positive subjects who started DAA, 47 (97.9%) showed a sustained virological response and one dropped-out in follow-up after DAA treatment. No subject had any adverse event. CONCLUSIONS: This model of HCV screening and linkage to care seems effective to eliminate HCV infectionin a difficult-to-reach and to-treat population, such as undocumented migrants and low-income refugees. The participation of cultural mediators in the study made possible a better interaction between migrants and physicians, as is evident from the large number of subjects enrolled. Eliminating HCV among migrants will have a long-term positive impact from a public health and healthcare perspective by reducing the number of individuals who potentially develop HCV-related complications such as liver cirrhosis and hepatocellular carcinoma and reducing the circulation of HCV in the regions that host them which often, as in the case of Italy, are low endemic for HCV infection.

Evidence supporting the effectiveness of Antimicrobial Stewardship (AMS) Programs in the emergency department (ED) setting is limited. We conducted a prospective cohort study to assess the efficacy of an AMS program in an ED and a short-stay observation unit. The intervention included periodic prospective audits (twice a week), conducted by four infectious disease consultants. Primary outcomes included the difference in the hospital mortality rate, antibiotic consumption, and the incidence of bloodstream infections (BSI) caused by multidrug resistant (MDR) bacteria, before March 2020-February 2021 and after March 2021-February 2022 when the program was implemented. Interrupted time-series analysis was performed to assess the effect of our program. During the 12-month program, we performed 152 audits and evaluated 366 antibiotic therapies out of a total of 853 patients admitted. In the intervention period, we observed a non-statistically significant decrease in total antibiotic consumption, with a change in level of - 31.2 defined daily dose/100 patient-days (PD) (p = 0.71). Likewise, we found no significant variations in the rate of BSI due to MDR Gram-positive (CT - 0.02 events/PD, p = 0.84), MDR Gram-negative bacteria (CT 0.08, p = 0.71), or Candida spp. (CT 0.008, p = 0.86). Conversely, we found a significant decrease in the mortality rate between the pre- and post-intervention periods (- 1.98 deaths/100 PD, CI - 3.9 to - 0.007, p = 0.049). The Antibiotic Stewardship Program in the ED was associated with a significant decrease in the mortality rate. More high-quality studies are needed to determine the most effective ASP strategies in this unique setting.

BACKGROUND: The aim of this study was to evaluate the prevalence of bacterial infections and antimicrobial prescriptions in a large cohort of COVID-19 patients and to identify the independent predictors of infection and antibiotic prescription. METHODS: All consecutive patients hospitalized for COVID-19 from March 2020 to May 2021 at 1 of the 17 centers participating in the study were included. All subjects showing a clinical presentation consistent with a bacterial infection with microbiological confirmation (documented infection), and/or a procalcitonin value >1 ng/mL (suspected infection) were considered as having a coinfection (if present at admission) or a superinfection (if acquired after at least 48 h of hospital stay). RESULTS: During the study period, of the 1993 patients, 42 (2.1%) presented with a microbiologically documented infection, including 17 coinfections and 25 superinfections, and 267 (13.2%) a suspected infection. A total of 478 subjects (24.5%) received an antibacterial treatment other than macrolides. No independent predictors of confirmed or suspected bacterial infection were identified. On the contrary, being hospitalized during the second wave of the pandemic (OR 1.35, 95% CI 1.18-1.97, p = 0.001), having a SOFA score ≥3 (OR 2.05, 95% CI 1.53-2.75, p < 0.001), a severe or critical disease (OR 1.66, 95% CI 1.24-2.23, p < 0.001), and a high white blood cell count (OR 1.03, 95% CI 1.004-1.06, p = 0.023) were all independently related to having received an antimicrobial prescription. CONCLUSIONS: Our study reported a high rate of antimicrobial prescriptions despite a limited number of documented or suspected bacterial infections among the large cohort of hospitalized COVID-19 patients.
ABSTRACT
BACKGROUND: No clear evidence supports the use of cefiderocol as first line treatment in A. baumannii infections. METHODS: We conducted an observational retrospective/prospective multicenter study including all patients> 18 years with carbapenem-resistant A. baumannii (CRAB) infections treated with cefiderocol, from June 12021 to October 30 2022. Primary endpoint was 30-day mortality, secondary end-points the clinical and microbiological response at 7 days and at the end of treatment. Furthermore, we compared the clinical and microbiological outcomes among patients who received cefiderocol in monotherapy or in combination. RESULTS: Thirty-eight patients with forty episodes of infection were included [mean age 65 years (SD+16.3), 75% males, 90% with hospital-acquired infections and 70% showing sepsis or septic shock]. The most common infections included unknown source or catheter-related bacteremia (45%) and pneumonia (40%). We observed at 7 days and at the end of therapy a rate of microbiological failure of 20% and 10%, respectively, and of clinical failure of 47.5% and 32.5%, respectively; the 30-day mortality rate was 47.5%. At multivariate analysis clinical failure at 7 days of treatment was the only independent predictor of 30-day mortality. Comparing monotherapy (used in 72.5%) vs. combination therapy (used in 27.5%), no differences were observed in mortality (51.7 vs 45.5%) and clinical (41.4 vs 63.7%) or microbiological failure (24.1 vs 9.1%). CONCLUSIONS: The findings of this study reinforce the effectiveness of cefiderocol in CRAB infections, also as monotherapy. However, prospective multicenter studies with larger sample sizes and a control group treated with standard of care are needed to identify the best treatment for CRAB infections.

To characterize viral hepatitis co-infections in a cohort of immigrants living in southern Italy. In a prospective multicenter study, all undocumented immigrants and low-income refugees consecutively evaluated for a clinical consultation at one of the five first-level clinical centers in southern Italy from January 2012 to February 2020 were enrolled. All subjects included in the study were screened for hepatitis B surface antigen (HBsAg), anti-hepatitis C virus (HCV) and anti-HIV; the HBsAg-positive were screened also for anti-delta. Of the 2923 subjects enrolled, 257 (8%) were HBsAg-positive alone (Control group B), 85 (2.9%) only anti-HCV-positive (Control group C), 16 (0.5%) HBsAg/anti-HCV-positive (Case group BC), and 8 (0.2%) HBsAg/anti-HDV-positive (Case group BD). Moreover, 57 (1.9%) subjects were anti-HIV-positive. HBV-DNA positivity was found less frequently in the 16 subjects in Case group BC (43%) and in the 8 in Case group BD (12.5%) than in the 257 in Control group B (76%; p = 0.03 and 0.0000, respectively). Similarly, HCV-RNA positivity was more frequent in Case group BC than in Control group C (75% vs. 44.7% p = 0.02). The subjects in Group BC had a lower prevalence of asymptomatic liver disease (12.5%) than Control group B (62.2%, p = 0.0001) and Control group C (62.3%, p = 0.0002). Conversely, liver cirrhosis was more frequently identified in Case group BC (25%) than in Control groups B and C (3.11% and 2.35%, p = 0.0000 and 0.0004, respectively). The present study contributes to the characterization of hepatitis virus co-infections in the immigrant population.

BACKGROUND: The prevalence of certain multidrug-resistant organisms (MDROs), especially Gram-negative bacteria, is dramatically increasing in patient care settings, including pediatric and neonatal units. However, most of the new drugs available for the treatment of MDROs have not yet been studied in children and newborns. CASE REPORT: We report the clinical case of a preterm neonate, born at 31 weeks gestation + 1 day of age by emergency Cesarean Section (CS), with a bloodstream infection (BSI) due to a Verona integron-borne metallo-ß-lactamase (VIM)-producing Klebsiella pneumoniae. We successfully treated the infection with cefiderocol in an off-label regimen at the following dose: loading dose 60 mg/kg and then 40 mg/kg every 8 h in extended infusion for 9 days. The baby showed a quick clinical and biochemical improvement and tolerated well the treatment. Follow-up blood cultures at 48 h after the start of cefiderocol were negative. CONCLUSIONS: Antimicrobial-resistant pathogens are of increasing concern in neonatal settings. More studies in this unique population are necessary to better describe the pharmacokinetic and pharmacodynamic profile of the new drugs against MDROs, such as cefiderocol, and to define a proper effective dose.
ABSTRACT
The presence of co-morbidities is associated with a poor outcome in patients with COVID-19. The aim of the present study was to investigate the outcomes of patients with SARS-CoV-2 infection and chronic kidney disease (CKD) in order to assess its impact on mortality and severity of disease. We performed a multicenter, observational, 1:2 matched case-control study involving seventeen COVID-19 Units in southern Italy. All the adults hospitalized for SARS-CoV-2 infection and with pre-existing CKD were included (Cases). For each Case, two patients without CKD pair matched for gender, age (+5 years), and number of co-morbidities (excluding CKD) were enrolled (Controls). Of the 2,005 patients with SARS-CoV-2 infection followed during the study period, 146 patients with CKD and 292 patients without were enrolled in the case and control groups, respectively. Between the Case and Control groups, there were no statistically significant differences in the prevalence of moderate (17.1% vs 17.8%, p=0.27) or severe (18.8% and 13.7%, p=0.27) clinical presentation of COVID-19 or deaths (20.9% vs 28.1%, p=0.27). In the Case group, the patients dead during hospitalization were statistically higher in the 89 patients with CKD stage 4-5 compared to 45 patients with stages 1-3 CKD (30.3% vs 13.3%, p=0.03). Our data suggests that only CKD stage 4-5 on admission was associated with an increased risk of in-hospital death.
ABSTRACT
BACKGROUND: Since few data are available in the literature on the prevalence of anti-Delta-positive subjects in immigrant populations, the aim of the present study was to evaluate the demographic and virological characteristics of HDV infection in a large cohort of immigrants living in southern Italy. METHODS: Between January 2012 and February 2020 all immigrants attending one of the 5 first- level centers were enrolled and screened for HBsAg, the HBsAg-positive for anti-Delta and if positive, for HDV-RNA and HDV genotype. RESULTS: Of the 3521 immigrants observed in the study period, 3417 (97.0%) agreed to be screened; they were mainly males (61%), with a median age of 27 years (IQR 8-74) and came prevalently (58%) from sub-Saharan Africa. Of the 3417 patients enrolled, 319 (9%) subjects were HBsAg-positive, and of those, 8 (2.5%) were anti-Delta-positive. No difference in the demographic and epidemiological characteristics was observed between the anti-Delta-negative vs -positive. Of the 8 anti-Delta-positive subjects, only one was HDV-RNA-positive (viral load: 7050 IU/mL), genotype 1, with clinical signs of cirrhosis. CONCLUSIONS: the present study showed a prevalence of HDV of 2.5% in a large cohort of asymptomatic immigrants, suggesting the need for screening campaigns for viral infections including delta hepatitis in this population.

Antimicrobial resistance represents a serious threat for global health, causing an unacceptable burden in terms of morbidity, mortality and healthcare costs. In particular, in 2017, carbapenem-resistant organisms were listed by the WHO among the group of pathogens for which novel treatment strategies are urgently needed. Fortunately, several drugs and combinations have been introduced in recent years to treat multi-drug-resistant (MDR) bacteria. However, a correct use of these molecules is needed to preserve their efficacy. In the present paper, we will provide an overview on the epidemiology and mechanisms of resistance of the most common MDR Gram-negative bacteria, proposing a treatment algorithm for the management of infections due to carbapenem-resistant bacteria based on the most recent clinical evidence.
ABSTRACT
Few data are available regarding the effectiveness of anti-SARS-CoV-2 vaccine in immunocompromised patients. Vaccination may have a suboptimal efficacy in this population, in particular if patients are exposed to anti-B-cell therapy. We report the virological and clinical characteristics of a patient with follicle center lymphoma under bimonthly maintenance therapy with obinutuzumab, an anti-CD20 monoclonal antibody. Despite three doses of BNT162b2 vaccine, the patient was infected by the SARS-CoV-2 Omicron variant. After an initial period of clinical and molecular remission due to early therapy with sotrovimab, the patient experienced a fatal relapse sustained by the same viral strain.
ABSTRACT
BACKGROUND: Cardiovascular disease (CVD) is a major cause of morbidity and mortality after liver transplantation, mostly in patients transplanted for nonalcoholic steatohepatitis, obesity and diabetes. Few data exist on cardiovascular diseases among patients transplanted for viral hepatitis. OBJECTIVE: Our aim is to clarify the cardiovascular risk and subclinical vascular damage among liver transplant recipients for chronic viral hepatitis (i.e. hepatits C virus, hepatis B virus and hepatitis D virus infection). METHODS: Adult patients (age ≥ 18 years) with orthotopic liver transplants (OLT) due to viral hepatitis who signed informed consent, and were admitted for a routine follow-up between June 2019 and September 2020 at the Infectious Disease outpatient clinic of the University of Campania Luigi Vanvitelli, Naples, Italy, were prospectively enrolled. An estimation of cardiovascular risk was assessed using three main risk charts, echocolor-Doppler of epiaortic vessels was performed to assess subclinical Intima-Media changes. RESULTS: A total of 161 patients were evaluated; of these 15 were excluded because not affected by viral hepatitis. 146 patients were considered. 83 patients (56.8%) were considered at high cardiovascular risk according to Framingham, 54 patients (36.9%) to American Heart Association Arteriosclerotic Cardiovascular Disease (ASCVD) score and 19 (13.0%) to Heart Score. Only 8 patients (5.4%) showed a normal carotid ultrasound, while 52 patients (35.6%) had a carotid artery Intima-Media Thickness (IMT) and 86 (58.9%) an atherosclerotic plaque. CONCLUSIONS: Liver transplant recipients for virus-related associated liver disease are, in light of the high percentage of carotid lesions, at high risk of CVD. Risk charts compared to subclinical carotid lesions which represent damage already established and a real localization of the disease, seem to underestimate the cardiovascular risk. A chronic inflammatory status, could play a key role. It's important to raise the awareness of cardiovascular risk in liver transplant patients to prevent cardiovascular diseases and improve the timing of early diagnosis of premature vascular lesions.

OBJECTIVES: To compare the clinical and microbiological outcomes of patients treated with beta-lactam monotherapy or combination therapy for Pseudomonas aeruginosa infections. DATA SOURCES: MEDLINE, Google Scholar and the Cochrane Library. STUDY ELIGIBILITY CRITERIA AND INTERVENTIONS: Experimental and observational studies published as full papers up to December 2020 that compared the efficacy of beta-lactams used as monotherapy or in combination with other active agents as empirical or targeted therapy for bloodstream infections or hospital-acquired pneumonia/ventilator-associated pneumonia due to P. aeruginosa were included in this meta-analysis. The outcomes evaluated were in-hospital mortality rate, 14-day- or 30-day-mortality rate, microbiological cure rate and clinical cure rate. RESULTS: Of 8363 citations screened, six randomized controlled trials, six prospective cohort studies and 21 retrospective cohort studies were included in the analysis, accounting for a total of 3861 subjects. Considering the 14 studies evaluating empirical therapy, no significant difference in mortality rate was observed between the two groups [relative risk (RR) 1.06, 95% confidence interval (CI) 0.86-1.30; P=0.6]. Similar findings were obtained among the 18 studies analysing targeted therapy (RR 1.04, 95% CI 0.83-1.31; P=0.708); however, grouping the studies by design, higher mortality was observed among patients receiving monotherapy in five prospective studies (RR 1.37, 95% CI 1.06-1.79; P=0.018). Finally, no difference was observed between groups in terms of microbiological cure and clinical cure. CONCLUSIONS: This meta-analysis demonstrated no difference in mortality rate, clinical cure rate and microbiological cure rate in patients treated with beta-lactam monotherapy or combination therapy for P. aeruginosa infections.

Reactivation of overt or occult HBV infection (HBVr) is a well-known, potentially life-threatening event which can occur during the course of immunosuppressive treatments. Although it has been described mainly in subjects receiving therapy for oncological or hematological diseases, the increasing use of immunosuppressant agents in non-oncological patients observed in recent years has raised concerns about the risk of reactivation in several other settings. However, few data can be found in the literature on the occurrence of HBVr in these populations, and few clear recommendations on its management have been defined. The present paper was written to provide an overview of the risk of HBV reactivation in non-neoplastic patients treated with immunosuppressive drugs, particularly for rheumatological, gastrointestinal, dermatological and neurological diseases, and for COVID-19 patients receiving immunomodulating agents; and to discuss the potential strategies for prevention and treatment of HBVr in these settings.
ABSTRACT
OBJECTIVES: We evaluated the effect of the pandemic on the disruption of a persuasive educational antimicrobial stewardship program (ASP) conducted in a university hospital in southern Italy. METHODS: In March 2020, the ASP, which began in January 2017 and was carried out at different times in 10 wards, was stopped due to the COVID-19 pandemic. We conducted an observational study with interrupted time series analysis to compare the antibiotic consumption and costs, average length of hospital stay and in-hospital mortality between 12 months before and 9 months after the interruption. RESULTS: Four medical, four surgical wards and two ICUs were included in the study, for a total of 35,921 patient days. Among the medical wards we observed after the interruption a significant increase in fluoroquinolone use, with a change in trend (CT) of 0.996, p = 0.027. In the surgical wards, we observed a significant increase in the overall consumption, with a change in level (CL) of 24.4, p = 0.005, and in the use of third and fourth generation cephalosporins (CL 4.7, p = 0.003). In two ICUs, we observed a significant increase in piperacillin/tazobactam and fluoroquinolone consumption (CT 9.28, p = 0.019, and 2.4, p = 0.047). In the wards with a duration of ASP less than 30 months, we observed a significant increase in antibiotic consumption in the use of piperacillin/tazobactam and fluoroquinolones (CT 12.9, p = 0.022: 4.12, p = 0.029; 1.004, p = 0.011). CONCLUSIONS: The interruption of ASP during COVID-19 led to an increase in the consumption of broad-spectrum antibiotics, particularly in surgical wards and in those with a duration of ASP less than 30 months.
ABSTRACT
BACKGROUND: The aim of the present study was to investigate the outcome of patients with SARS-CoV-2 infection and dementia. PATIENTS AND METHODS: In a multicenter, observational, 1:2 matched case-control study all 23 patients with a history of dementia, hospitalized with a diagnosis of SARS-CoV-2 infection from February 28th 2020 to January 31st 2021 were enrolled. For each Case, 2 patients without dementia observed in the same period study, pair matched for gender, age (±5 years), PaO2/FiO2 (P/F) ratio at admission (<200, or >200), number of comorbidities (±1; excluding dementia) were chosen (Control group). RESULTS: The majority of patients were males (60.9% of Cases and Controls) and very elderly [median age 82 years (IQR: 75.5-85) in the Cases and 80 (IQR: 75.5-83.75) in the Controls]. The prevalence of co-pathologies was very high: all the Cases and 43 (93.5%) Controls showed a Charlson comorbidity index of at least 2. During hospitalization the patients in the Case group less frequently had a moderate disease of COVID-19 (35 vs. 67.4%, p = 0.02), more frequently a severe disease (48 vs. 22%, p = 0.03) and more frequently died (48 vs. 22%, p = 0.03). Moreover, during coronavirus disease 2019 (COVID-19), 14 (60.8%) patients in the Case group and 1 (2.1%; p < 0.000) in the Control group showed signs and symptoms of delirium. CONCLUSION: Patients with dementia are vulnerable and have an increased risk of a severe disease and death when infected with COVID-19.
ABSTRACT
The objectives of the present study were to provide a snapshot analysis of antibiotic appropriateness in two hospitals in Southern Italy in three specific areas, surgical, medical and intensive care, and to evaluate the risk factors associated with inappropriateness in antimicrobial prescriptions. We conducted a multicentre observational study in two hospitals in the Campania region. We collected data of all patients admitted on the day of evaluation to antibiotic therapy or prophylaxis through a case report form. The primary outcome was to assess the inappropriateness of antibiotic prescribing, related to the spectrum, dose, route of administration and duration of treatment-in particular, to assess whether there was a difference in the adequacy of the prescriptive practice in the medical, surgical and intensive sectors. Prescriptive inappropriateness was more frequently observed in surgical units (79.8% of the 104 antimicrobial prescriptions) than in medical units (53.8% of the 65 prescriptions, p = 0.0003) or in intensive care units (64.1% of the 39 prescriptions, p = 0.052). The reasons for the inappropriate antimicrobial prescriptions were similar in the three areas evaluated: antimicrobial unnecessary and antimicrobial not recommended were the most frequent reasons for inappropriateness. Not participating in an antimicrobial stewardship program (ASP) was identified as a factor associated with inappropriate antimicrobial prescriptions in medical and surgical units, but not in Intensive Care Units (ICUs). ASPs may enhance the appropriateness of antimicrobial prescriptions especially in medical and surgical units. In ICUs, specific programs able to limit empirical therapies and encourage the collection of microbiological samples may be useful to set up targeted therapies and to design antimicrobial protocols.
ABSTRACT
To evaluate the effect that an education-based Antimicrobial stewardship program (ASP) implemented in two hospitals in southern Italy had on the quality and appropriateness of antibiotic prescription. We conducted a multicenter observational study in two hospitals in the Campania region. Only some departments of both hospitals were already participating in the ASP. We collected data on all patients admitted on the day of evaluation in antibiotic therapy or prophylaxis through a case report form. The primary outcome was to investigate the difference in the appropriateness of the antibiotic prescriptive practice in the departments that had joined the ASP and in those that had not participated in the project (non-ASP). The total number of patients assessed was 486. Of these, 78 (16.05%) were in antibiotic prophylaxis and 130 (26.7%) in antibiotic therapy. The prescriptive appropriateness was better in the units that had joined ASP than in those that had not, with respectively 65.8% versus 22.7% (p < 0.01). Patients in the non-ASP units more frequently received unnecessary antibiotics (44.9% versus 0%, p = 0.03) and, as surgical prophylaxis, the use of antibiotics not recommended by the guidelines (44.2% versus 0%, p = 0.036). Multivariable analysis of the factors associated with prescriptive appropriateness identified ASP units (p = 0.02) and bloodstream or cardiovascular infections (p = 0.03) as independent predictors of better prescriptive appropriateness. The findings of the present study reinforce the importance of adopting an educational ASP to improve the quality of antimicrobial prescription in clinical practice.
ABSTRACT
BACKGROUND AND AIM: The aim of the present study was to assess the diagnostic performance of an LFA compared with an ELISA test in a cohort of HWs operating in a COVID-19 unit of a teaching hospital in southern Italy. METHODS: We performed an observational, prospective, interventional study including 65 COVID-19 unit personnel. On a total of 196 serum samples (at least 2 serum samples for each HW), LFA and ELISA tests for SARS-COV-2 IgG and IgM were performed. Also, 32 serum samples of SARS-CoV-2 RNA positive patients at least 21 days before sampling, and 30 serum samples of patients obtained up to November 2019, before COVID-19 outbreak in China, were used as positive and negative controls, respectively. FINDINGS: Of the 65 HWs enrolled, 6 were positive in LFA; overall, of the 196 serum samples, 20 were positive in LFA. All ELISA tests performed on serum samples collected from HWs were negative. The specificity of LFAs was 90.77% considering the 65 HWs and 89.80% considering all the 196 health workers serum samples analyzed. Considering the data on HWs, ELISA test for SARS-COV-2 antibodies showed a specificity of 100%, including all the 196 serum samples collected, and 100% including the 65 HWs. The ELISA and LFAs performed after 21 days last COVID-19 patient was discharged were all negative. CONCLUSION: LFAs compared to ELISA tests result in less specificity, considering COVID-19 negative personnel and patients. Thus, LFAs seem to be not adequate in the active surveillance of HWs.
