RESUMO

BACKGROUND: Periprocedural prophylaxis in medicine encompasses the set of measures (physical, chemical, and pharmacological) used to reduce the risk of infection. Antibiotic prophylaxis (AP) refers to the administration of a short-term regimen of antibiotics shortly before a medical procedure to reduce the risk of infectious complications that can result from diagnostic and therapeutic interventions. The outspreading growth of multidrug-resistant bacterial species and changes in the bacterial local ecosystem have impeded the development of a unique scheme of AP in urology. OBJECTIVES: To review the literature and current guidelines regarding AP for urological diagnostic and therapeutic procedures, and to define agents, timing, and occasions when administering pharmacological prophylaxis. Secondly, according to current literature, to open new scenarios where AP can be useful or useless. RESULTS: Major gaps in evidence still exist in this field. AP appears useful in many invasive procedures and some sub-populations at risk of infectious complications. AP is not routinely recommended for urodynamic exams, diagnostic cystoscopy, and extracorporeal shock-wave lithotripsy. The available data regarding the use of AP during the transperineal prostate biopsy are still unclear; conversely, in the case of the transrectal approach AP is mandatory. AP is still considered the gold standard for the prevention of postoperative infective complications in the case of ureteroscopy, percutaneous nephrolithotomy, endoscopic resection of bladder tumor, endoscopic resection of the prostate, and prosthetic or major surgery. CONCLUSION: The review highlights the complexity of determining the appropriate candidates for AP, emphasizing the importance of considering patient-specific factors such as comorbidities, immunocompetence, and the nature of the urologic intervention. The evidence suggests that a one-size-fits-all approach may not be suitable, and a tailored strategy based on the specific procedure and patient characteristics is essential.

RESUMO

IMPORTANCE: Candidemia (bloodstream invasion by Candida species) is a major fungal disease in humans. Despite the recent progress in diagnosis and treatment, therapeutic options are limited and under threat of antimicrobial resistance. The disease mortality remains high (around 40%). In contrast with deep-seated invasive candidiasis, particularly that occurring in patients with hematologic malignancies and organ transplants, patients with candidemia are often not immunocompromised and therefore able to mount memory anticandidal immune responses, perhaps primed by Candida commensalism. We investigated antibody immunity in candidemia patients and report here on the ability of these patients to produce antibodies that react with Candida antigens. In particular, the patients with high titers of IgG reactive with two immunodominant, virulence-associated antigens (Als3 and MP65) had a higher 30-day survival. If confirmed by controlled, prospective clinical studies, our data could inform the development of antibody therapy to better treat a severe fungal infection such as candidiasis.

RESUMO

OBJECTIVE: COVID-19 pandemic has changed in-hospital care and was linked to superimposed infections. Here, we described epidemiology and risk factors for hospital-acquired bloodstream infections (HA-BSIs), before and during COVID-19 pandemic. METHODS: This retrospective, observational, single-center real-life study included 14,884 patients admitted to hospital wards and intensive care units (ICUs) with at least one blood culture, drawn 48 h after admission, either before (pre-COVID, N = 7382) or during pandemic (N = 7502, 1203 COVID-19+ and 6299 COVID-19-). RESULTS: Two thousand two hundred and forty-five HA-BSI were microbiologically confirmed in 14,884 patients (15.1%), significantly higher among COVID-19+ (22.9%; ptrend < .001). COVID-19+ disclosed a significantly higher mortality rate (33.8%; p < .001) and more ICU admissions (29.7%; p < .001). Independent HAI-BSI predictors were: COVID-19 (OR: 1.43, 95%CI: 1.21-1.69; p < .001), hospitalization length (OR: 1.04, 95%CI: 1.03-1.04; p < .001), ICU admission (OR: 1.38, 95%CI: 1.19-1.60; p < .001), neoplasms (OR:1.48, 95%CI: 1.34-1.65; p < .001) and kidney failure (OR: 1.81, 95%CI: 1.61-2.04; p < .001). Of note, HA-BSI IRs for Acinetobacter spp. (0.16 × 100 patient-days) and Staphylococcus aureus (0.24 × 100 patient-days) peaked during the interval between first and second pandemic waves in our National context. CONCLUSIONS: Patients with HA-BSI admitted before and during pandemic substantially differed. COVID-19 represented a risk factor for HA-BSI, though not confirmed in the sole pandemic period. Some etiologies emerged between pandemic waves, suggesting potential COVID-19 long-term effect on HA-BSIs.

RESUMO

The role of empiric antifungals for post-surgical abscesses (PSAs) is controversial, and international guidelines on invasive mycoses focus on bloodstream infections. We analyzed a retrospective cohort of 319 patients with PSA at a tertiary-level hospital in Italy during the years 2013-2018. Factors associated with empiric antifungal administration were analyzed and compared with factors associated with fungal isolation from the abdomen. Forty-six patients (14.4%) received empiric antifungals (65.2% azoles). Candida was isolated in 34/319 (10.7%) cases, always with bacteria. Only 11/46 patients receiving empirical antifungals had abdominal Candida. Only 11/34 patients with a fungal isolate received empiric antifungal therapy. Upper GI surgery (OR: 4.76 (CI: 1.95-11.65), p = 0.001), an intensive care unit stay in the previous 90 days (OR: 5.01 (CI: 1.63-15.33), p = 0.005), and reintervention within 30 days (OR: 2.52 (CI: 1.24-5.13), p = 0.011) were associated with empiric antifungals in a multivariate analysis, while pancreas/biliary tract surgery was associated with fungal isolation (OR: 2.25 (CI: 1.03-4.91), p = 0.042), and lower GI surgery was protective (OR: 0.30 (CI: 0.10-0.89), p = 0.029) in a univariate analysis. The criteria for empiric antifungal therapy in our practice seem to be inconsistent with the risk factors for actual fungal isolation. Better guidance for empiric therapy should be provided by wider studies.

RESUMO

We explored the potential link between chronic inflammatory arthritis and COVID-19 pathogenic and resolving macrophage pathways and their role in COVID-19 pathogenesis. We found that bronchoalveolar lavage fluid (BALF) macrophage clusters FCN1+ and FCN1+SPP1+ predominant in severe COVID-19 were transcriptionally related to synovial tissue macrophage (STM) clusters CD48hiS100A12+ and CD48+SPP1+ that drive rheumatoid arthritis (RA) synovitis. BALF macrophage cluster FABP4+ predominant in healthy lung was transcriptionally related to STM cluster TREM2+ that governs resolution of synovitis in RA remission. Plasma concentrations of SPP1 and S100A12 (key products of macrophage clusters shared with active RA) were high in severe COVID-19 and predicted the need for Intensive Care Unit transfer, and they remained high in the post-COVID-19 stage. High plasma levels of SPP1 were unique to severe COVID-19 when compared with other causes of severe pneumonia, and IHC localized SPP1+ macrophages in the alveoli of COVID-19 lung. Investigation into SPP1 mechanisms of action revealed that it drives proinflammatory activation of CD14+ monocytes and development of PD-L1+ neutrophils, both hallmarks of severe COVID-19. In summary, COVID-19 pneumonitis appears driven by similar pathogenic myeloid cell pathways as those in RA, and their mediators such as SPP1 might be an upstream activator of the aberrant innate response in severe COVID-19 and predictive of disease trajectory including post-COVID-19 pathology.

RESUMO

Background and Objectives: Fever is one of the most common presenting complaints in the Emergency Department (ED). The role of serum procalcitonin (PCT) determination in the ED evaluation of adults presenting with fever is still debated. The aim of this study was to evaluate if, in adults presenting to the ED with fever and then hospitalized, the early PCT determination could improve prognosis. Materials and Methods. This is a retrospective, mono-centric study, conducted over a 10-year period (2009-2018). We analyzed consecutive patients ≥18 years admitted to ED with fever and then hospitalized. According to quick sequential organ failure assessment (qSOFA) at admission, we compared patients that had a PCT determination vs. controls. Primary endpoint was overall in-hospital mortality; secondary endpoints were in-hospital length of stay, and mortality in patients with bloodstream infection and acute respiratory infections. Results. The sample included 12,062 patients, median age was 71 years and 55.1% were men. In patients with qSOFA ≥ 2 overall mortality was significantly lower if they had a PCT-guided management in ED, (20.5% vs. 26.5%; p = 0.046). In the qSOFA < 2 group the mortality was not significantly different in PCT patients, except for those with a final diagnosis of bloodstream infection. Conclusions. Among adults hospitalized with fever, the PCT evaluation at ED admission was not associated with better outcomes, with the possible exception of patients affected by bloodstream infections. However, in febrile patients presenting to the ED with qSOFA ≥ 2, the early PCT evaluation could improve the overall in-hospital survival.

RESUMO

OBJECTIVES: Surgical antibiotic prophylaxis (SAP) represents a major indication of antibiotic consumption worldwide. The present study aims to report the results of an enabling, long-term AMS intervention conducted between 2013 and 2019 on an Italian University Hospital performing more than 40.000 surgical interventions per year. METHODS: SAP inappropriateness was defined according to the ASHP guidelines and divided in four main categories: indication, selection and dosing, duration, timing. Between 2013 and 2019, we conducted a continuative AMS intervention over 14 surgical departments that included enablement, review of selected clinical records and feedback. RESULTS: We collected a total of 789 SAP prescribed to 735 patients (mean age 56.7 ± 17.8y). Overall, guideline adherence improved from 36.6% (n = 149) at baseline to 57.9% (n = 221) post-intervention (P <  0.0001). A significant improvement (P <  0.001) was also detected for each category: indication (from 58.5 to 93.2%), selection and dosing (from 58.5 to 80.6%), timing (from 92.4 to 97.6%), duration (from 71 to 80.1%). CONCLUSIONS: Though results cannot be generalized to all hospital populations, enabling AMS interventions may be effective in establishing a sustained improvement in SAP appropriateness rates. Once identified the main causes of SAP inappropriateness, tailored AMS interventions for each department may be beneficial. Further studies are needed to evaluate specific outcomes as incidence of surgical site infections and antimicrobial resistance.

RESUMO

A low count of CD4+ and CD8+ lymphocytes is a hallmark laboratory finding in the coronavirus disease 2019 (COVID-19). Using flow cytometry, we observed significantly higher CD95 (Fas) and PD-1 expression on both CD4+ T and CD8+ T cells in 42 COVID-19 patients when compared to controls. Higher CD95 expression in CD4+ cells correlated with lower CD4+ counts. A higher expression of CD95 in CD4+ and CD8+ lymphocytes correlated with a lower percentage of naive events. Our results might suggest a shift to antigen-activated T cells, expressing molecules increasing their propensity to apoptosis and exhaustion during COVID-19 infection.

RESUMO

We evaluated patients admitted through our ED for community-acquired pneumonia (CAP) to assess the relevance of an early procalcitonin (PCT) determination on patient's outcomes. METHODS: We reviewed all patients admitted for CAP in a 10 years period (2008-2017). Patients were stratified according to age groups: (18-65 years; 65-84 years; and ≥85 years), CURB-65 score, need for ventilation, Sepsis-3 criteria at admission, enrollment period, blood culture in ED. In-hospital mortality rate and length of hospital stay (LOS) were compared between patients that had an early PCT determination in ED vs. patients admitted without. RESULTS: Our study cohort consisted of 4056 CAP patients, age 76 [IQ range 64-84] years. We enrolled 1039 patients <65 years old, 2015 aged 65-84 years, and 1002 aged ≥85 years. Overall, the early PCT determination in ED was not associated to a reduced LOS (p=0.630), nor to a reduced mortality rate (p=0.134). However, in patients ≥ 85 years, the PCT determination in ED was associated with lower mortality in those with CURB-65 ≥ 2, and Charlson's score ≥ 2 (p=0.033 and p=0.002, respectively). CONCLUSIONS: Although an early PCT assessment in ED was not associated with better outcomes in term of LOS and mortality in patients with CAP, our findings suggest that it might be associated with reduced mortality in patients ≥ 85 years with severe CAP or high comorbidity.

RESUMO

Despite evidence supporting the effectiveness of best practices in infection prevention and management, many healthcare workers fail to implement them and evidence-based practices tend to be underused in routine practice. Prevention and management of infections across the surgical pathway should always focus on collaboration among all healthcare workers sharing knowledge of best practices. To clarify key issues in the prevention and management of infections across the surgical pathway, a multidisciplinary task force of experts convened in Ancona, Italy, on May 31, 2019, for a national meeting. This document represents the executive summary of the final statements approved by the expert panel.

RESUMO

BACKGROUND: Infective endocarditis (IE) is characterized by high rates of in-hospital death, and Staphylococcus aureus infection predicts a worse prognosis. We aimed to assess if admission inflammatory biomarkers (white blood cell - WBC - count, C-reactive protein - CRP, and procalcitonin) are informative on microbiological etiology and short-term outcomes. METHODS: Data from 236 patients admitted for IE from January 2013 to June 2018 were retrieved from a multicenter registry. RESULTS: Fifty-two patients (22%) were infected by S. aureus. WBC, CRP and procalcitonin had area under the curve (AUC) values for S. aureus infection of 0.595, 0.675, and 0.727, respectively. Adding procalcitonin to WBC improved discrimination over WBC alone (p = 0.045), and procalcitonin predicted S. aureus infection independently from the other inflammatory biomarkers and patient characteristics. Patients with WBC ≥ 12,800/mm3, CRP ≥ 130 mg/L, and procalcitonin ≥ 1.7 ng/mL had an almost 20-fold higher risk of S. aureus infection than patients with all biomarkers < cut-offs. AUC values for in-hospital death were 0.702, 0.725 and 0.727 for the WBC, CRP, and procalcitonin, respectively. Among inflammatory biomarkers, WBC and procalcitonin independently predicted in-hospital death. Procalcitonin refined risk stratification when added to WBC, and to the combination of WBC and CRP. Patients with WBC ≥ 10,535/mm3, CRP ≥ 85 mg/dL, and procalcitonin ≥ 0.4 ng/mL had a 27-fold higher risk of in-hospital death than patients with all biomarkers < cut-offs. CONCLUSIONS: Among patients with IE, high levels of inflammatory biomarkers on admission, particularly procalcitonin, are associated with a higher likelihood of S. aureus infection, and a higher risk of in-hospital mortality.

RESUMO

To investigate the prognostic role of procalcitonin (PCT) assessment and blood culture (BC) acquisition in the emergency department (ED) in patients with urinary tract infection (UTI) or urosepsis. We enrolled patients admitted for UTI to our ED over a 10-year period. Mortality and in hospital length of stay (LOS) were compared between patients with UTI or urosepsis who had sampling for PCT levels and BC taken in the ED (ePCT group-eBC group) and those who had not (no-ePCT group-no-eBC group). 1029 patients were analyzed, 52.7% of which were female. Median age was 77 [65-83]; 139 patients (13.5%) had complicated UTI. Median LOS was 10 [7-17] days. In the ePCT group, LOS was 10 [7-16] days, vs. 10 [7-17] (p = 0.428) in the no-ePCT group. In the eBC group, LOS was 10 [6-16] days vs. 10 [7-17] days (p = 0.369) in the no-eBC group. The overall mortality rate was 6.6%. The mortality rate was not affected by early PCT determination (6% in the ePCT group vs. 6.9% in the no-ePCT group, p = 0.584). Similarly, the mortality rate was not different in the eBC group as compared to the no-eBC group (5.4% vs. 6.9%, p = 0.415). Performance of ePCT or eBC testing made no significant difference in terms of improvement of mortality rates in septic patients (11.4% vs. 7.2%; p = 0.397 and 8.8% vs. 9.8%; p = 0.845, respectively). The prognostic relevance of early evaluation of PCT and BC in the ED of patients with febrile UTI appears limited. In complicated UTI patients, PCT and BC testing may be more appropriate in the context of improving antibiotic stewardship, or as an integral component of PCT-guided standardized protocols.

RESUMO

OBJECTIVE: Antibiotic prophylaxis (AP) is useful to prevent antimicrobial overuse, misuse and abuse, as well against the occurrence of surgical site infections (SSIs). This study aimed to describe the implementation of a quality improvement intervention on AP for elective surgery, as informal interviews showed a lower than expected compliance with internal recommendations, and to evaluate intervention's effect in terms of main drug consumption. DESIGN: A quality improvement intervention on all elective cases within 14 main surgical departments was performed. SQUIRE 2.0 guidelines were used in designing and reporting. SETTING: The intervention was implemented in an Italian Teaching Hospital 2 years after the adoption of internal evidence-based AP recommendations. PARTICIPANTS: Professionals involved in elective surgery. INTERVENTIONS: The intervention was structured into two phases: a survey was conducted during two non-consecutive weeks period (April-May 2013) to assess the adherence to the international guidelines in AP; survey's results were presented and discussed with all the surgical teams (December 2013-April 2014). MAIN OUTCOME MEASURES: Impact on cefazolin consumption (in defined daily doses per 100 procedures). RESULTS: Data of AP for 653 surgical procedures in terms of type, timing, duration, excess and defect were analyzed. An optimal AP rate resulted in 48.1% cases. Reduction in cefazolin use (-21.5%) and cost (-22.9%) was registered. CONCLUSIONS: Though results cannot be generalized to all hospital populations, the implemented intervention is likely to improve AP consequently improving quality of care and reducing costs. Further studies are needed to evaluate specific outcomes such as rate of SSIs and antibiotic resistance.

RESUMO

BACKGROUND: Primary intrahepatic lithiasis is defined by the presence of gallstones at the level of cystic dilatations of the intrahepatic biliary tree. Liver resection is considered the treatment of choice, with the purpose of removing stones and atrophic parenchyma, also reducing the risk of cholangiocarcinoma. However, in consequence of the considerable incidence of infectious complications, postoperative morbidity remains high. The current study was designed to evaluate the impact of preoperative bacterial colonization of the bile ducts on postoperative outcome. METHODS: The clinical records of 73 patients treated with liver resection were reviewed and clinical data, operative procedures, results of bile cultures, and postoperative outcomes were examined. RESULTS: Left hepatectomy (38 patients) and left lateral sectionectomy (19 patients) were the most frequently performed procedures. Overall morbidity was 38.3 %. A total of 133 microorganisms were isolated from bile. Multivariate analysis identified previous endoscopic or percutaneous cholangiography (p = 0.043) and preoperative cholangitis (p = 0.003) as the only two independent risk factors for postoperative infectious complications. CONCLUSIONS: Postoperative morbidity was strictly related to the preoperative biliary infection. An effective control of infections should be always pursued before liver resection for intrahepatic stones and an aggressive treatment of early signs of sepsis should be strongly emphasized.

RESUMO

AIM: To assess epidemiological features of patients for which a consultation by the infectious diseases consultation team was required, and the rate of clinical advice that led to resource-saving advice (R-SA): discontinuation of inappropriate therapy or prophylaxis, de-escalation and switch from parenteral to oral therapy. MATERIALS & METHODS: An infectious diseases consultation team was implemented in a 1100-bed university hospital in Italy. RESULTS: The most frequent infections for which an infectious diseases consultancy was required were pneumonia, bloodstream infections (17% by Candida) and urinary tract infections. In 828 patients (41.4%), interventions with the possibility of R-SA were suggested. CONCLUSION: Resource-saving advices were possible in 41% of cases. Recent surgery, having a central venous catheter, bloodstream, abdominal, surgical site or bone and joint infections were correlated to a higher probability of receiving R-SA.

RESUMO

BACKGROUND: Infliximab is a chimeric monoclonal antibody, belonging to the class of anti-tumor necrosis factor-α (TNF-α) agents, approved for the treatment of psoriasis and psoriatic arthritis. Drugs of this class are known to be associated with an infective risk, probably because they interfere with inflammatory and immune response at different levels. Although cutaneous Staphylococcus aureus infections seem to be more frequent than any other infection in the course of anti-TNF-α treatment, only a few case reports in the literature deal with this side effect, and, in particular, with its management. OBJECTIVE: Our aim was to report a case of recurrent methicillin-sensitive S aureus (MSSA) cutaneous abscesses during therapy with infliximab and successful management. CASE SUMMARY: In July 2009, a 53-year-old white woman (weighing 85 kg) affected by psoriasis and psoriatic arthritis was administered infliximab (5 mg/kg IV), based upon clinical appearance and previous unsuccessful treatment with cyclosporine, methotrexate, etanercept, and adalimumab. Three days after the first 3 infusions (at weeks 0, 2, and 6) she complained about the recurrent onset of painful, erythematous, indurated, and pus-draining cutaneous nodules located on her abdomen. The swab always revealed the presence of MSSA, and antibiotic oral therapy with amoxicillin + clavulanic acid (875 + 125 mg BID for 7 days) was established, with complete resolution of the abscesses. Routine laboratory findings were in normal ranges, with the exception of an elevated erythrosedimentation rate and an increased white blood cell count (range, 13,000-15,000/mm(3)) with neutrophilia (range, 75%-80%). HIV infection was ruled out. In agreement with the infectious disease consultant, 1 day before the fourth infusion, a prophylactic antibiotic therapy with amoxicillin + clavulanic acid (875 + 125 mg BID for 5 days) was added to the therapeutic regimen. This treatment schedule was successfully repeated at each following infusion (every 8 weeks), and no recurrence of skin abscesses was observed. The patient provided signed authorization for publication of this case. CONCLUSIONS: This case report describes a woman with psoriasis and psoriatic arthritis who developed MSSA skin abscesses after each of the first 3 infliximab infusions, which did not recur for the next 6 infusions after amoxicillin + clavulanic acid was added to her regimen, pre- and 4 days postinfusion. Adequately designed, placebo-controlled, double-blind trials are needed to determine whether such prophylactic antibiotic treatment is well tolerated or effective for this common complication of therapy with anti-TNF-α agents, when withdrawal of the drug is not advisable, as in this case.

RESUMO

In order to analyze the clinical relevance of the pharmacokinetic interactions between vinblastine and antiretrovirals described in literature, we evaluated all HIV-infected patients with Hodgkin's lymphoma treated with vinblastine-containing regimens and combination antiretroviral therapy, in a single clinical center. The use of protease inhibitors was independently associated with WHO grade III-IV neutropenia. Moreover, an inverse correlation between dosage of ritonavir and mean nadir neutrophil count was found. The concomitant administration of vinblastine-containing chemotherapy regimens with protease inhibitors can lead to higher levels of neutropenia than those of different classes of drugs such as nonnucleoside reverse transcriptase inhibitors or integrase inhibitors.

RESUMO

BACKGROUND: Prevalence and factors associated with sexual dysfunction in HIV-positive women are poorly known. METHODS: This was a cross-sectional study in a cohort of HIV-infected women. Clinically stable women were invited to participate in a female sexual dysfunction (FSD) evaluation with Female Sexual Function Index (FSFI) exploring desire, arousal, lubrication, orgasm, pain and satisfaction. An FSFI score <23 was used for defining FSD. Variables evaluated included body appearance satisfaction, interference of body changes with habits, social life and attitudinal aspects of body image, health-related quality of life, hormonal assessment, menopause, cumulative exposure to antiretroviral drug classes and immune-virological parameters. Lipodystrophy was defined according to the HIV Outpatient Study definition. RESULTS: A total of 185 women completed the FSFI. The mean (+/-SD) age was 42 years (+/-5), 27% had CDC stage C, the mean (+/-SD) CD4+ T-cell count was 508 cells/microl (+/-251) and median HIV RNA was 1.7 log10 copies/ml (interquartile range 1.7-2.6). Among 161 evaluable patients, 59 (32%) reported FSD. In a multiple linear regression analysis, desire, arousal and satisfaction domains were associated with interference of body changes with habits, social life and attitudinal aspects of body image (beta = 0.22, 95% confidence interval [CI] 0.06-0.37; beta = 0.29, 95% CI 0.10-0.48; and beta = 0.20, 95% CI 0.02-0.38, respectively). Lubrication and orgasm domains were associated with body image satisfaction (beta = -0.49, 95% CI -0.88 - -0.10 and beta = -0.58, 95% CI -1.00 - -0.16, respectively). No significant associations with sex hormones, CDC stage, CD4+ T-cell count, HIV RNA viral load and cumulative exposure to antiretroviral drug classes were found. In women with FSD, severity of self-perceived abdominal fat accumulation showed a trend towards lower FSFI scores (ANOVA P = 0.02). CONCLUSIONS: FSD was highly prevalent in this cohort. Self-perceived body changes was identified as its major determinant.
