Abstract Background The clinical relevance and the potential prognostic role of persistently negative (1,3)-β-D-glucan (BDG) in adults with proven candidemia is unknown. Methods This retrospective study included all adults diagnosed with candidemia our tertiary university hospital from 2012–2017 who had at least 2 serum BDG determinations throughout the episode of fungemia (Fungitell Assay; positive cut-off ≥80pg/mL). Epidemiology and clinical outcomes were compared between patients with all negative versus any positive BDG tests. Poor clinical outcomes included complications due to candidemia or 30-day all-cause mortality. Results Overall, 26/148 (17.6%) candidemic adults had persistently negative BDG tests. These patients were less likely to present Candida growth in all 3 sets of blood cultures (15.4% vs 45.1%; P = .005) and had less severe clinical presentations (median Pitt score, 0 [interquartile range {IQR} 0–1] vs 1 [IQR 0–2] in patients with any positive BDG test; P = .039). Although adequate treatment was equally provided to both groups (96.2% in persistently negative group vs 93.4 in positive group; P = .599), the persistently negative group had a higher rate of microbiological clearance in the first follow-up blood cultures (92.3% vs 69.7% in positive group; P = .005), fewer complications due to candidemia (7.7% vs 33.6% in positive group; P = .008), a lower 30-day mortality rate (3.8% vs 23.8% in positive group; P = .004), and a shorter in-hospital stay (34 days [IQR 18–55] vs 51 days [IQR 35–91] in positive group; P = .003). In the multivariate analysis, persistently negative BDG tests were independently associated with better prognoses (odds ratio 0.12, 95% confidence interval 0.03–0.49; P = .003). Conclusions Candidemic patients with persistently negative BDG tests present a better prognosis than the comparative group, probably due to a lower systemic fungal burden. In this context, the appropriate use of persistently negative BDG results could be an aid to individualize therapeutic management in the near future.

Abstract Background Invasive candidiasis is a life-threatening infection with 40% mortality despite antifungal therapy[1] A retrospective chart review of results from our T2Candida Panels from March 2019 to March 2020 was conducted. We compared demographics, co-morbidities, days of antifungal use, length of stay (LOS) and mortality in patients with positive and negative assays. Results 271 assays were performed, 27 were positive and were compared to 81 negatives. Baseline demographics and co-morbidities were similar in both groups. All patients tested had >1 risk factor for candidemia. 78% were positive for C. albicans/C. tropicalis and 11% positive for C. glabrata/C. krusei and C. parapsilosis respectively. Blood cultures were positive in 8 individuals, of which 5 had a positive assay; among the other 3, one grew C. auris. All species in the T2Candida matched the blood cultures when available. β-D-glucan was positive in 82% of patients with positive T2 results vs 46% in the T2 negative group (p = 0.016). Antifungal administration within the time of assay collection was 54% in the negative group vs 74% in the positive group (p = 0.030). Mean duration of antifungal use were significantly lower in the negative group than the positive group (5.98 vs 17.55 days, p = 0.04). Demographics and Comorbidities Outcomes Cultures Conclusion T2Candida was an effective diagnostic and antimicrobial stewardship tool, leading to testing in high risk patients and reducing unnecessary antifungal use. Additional education is required for improved ordering of concurrent blood cultures. Negative results should be interpreted with caution in suspected invasive candidiasis with consideration for species not included in the panel. Disclosures All Authors: No reported disclosures

Objective: To compare the epidemiology and hospital course of patients with acute salpingitis with and without coincident human immunodeficiency virus (HIV) seropositivity.Methods: Patients admitted to the UMDNJ-University Hospital in Newark, New Jersey from January 1, 1991, to December 31, 1991, with acute salpingitis were studied.Results: Eight percent of all hospitalized patients with acute salpingitis were HIV-positive. The mean age of the HIV-negative group was 25.4 compared with 29.6 years in the HIV-positive group. Gonorrhea and chlamydia were present in 49% and 22%, respectively, in HIV-negatives and in 40% and 20% of HIV-positives. Two of 5 (40%) HIV-positive patients had tuboovarian abscesses compared with 12 of 59 (20%) HIV-negative patients. Three of 5 (60%) HIV-positive patients had admission WBC counts fewer than 10,000/mm3 compared to 6 of 59 (12%) of HIV-negatives (P = 0.024). The hospital stay was 5.4 days for HIV-positives and 5.8 days for HIV-negatives.Conclusions: Eight percent of hospitalized patients with acute salpingitis were HIV-seropositive. Neisseria gonorrhoeae and chlamydia were commonly found organisms in both groups. The initial WBC count was lower for HIV-positive patients. The hospital course of both groups was similar.

AbstractThe aim was to investigate the efficacy of prophylactic antibiotics for the prevention of febrile neutropenia (FN) during cabazitaxel therapy for castration-resistant prostate cancer (CRPC) with G-CSF. We retrospectively studied 443 cycles of cabazitaxel therapy given to 56 patients with CRPC at Keio University Hospital between May 2012 and August 2018. Statistical analysis was conducted to determine whether the combination of prophylactic G-CSF and antibiotics was more effective in preventing FN, compared with prophylactic G-CSF alone. Prophylactic PEG-G-CSF or G-CSF was administered in all 443 cycles. Only fluoroquinolones were used as prophylactic antibiotics and were administered in 328 cycles (74.0%). FN occurred in 5 cycles (1.1%). Prophylactic antibiotics were administered in 327 cycles (74.6%) in the FN-negative group and in only 1 cycle (20.0%) in the FN-positive group. Chi-square test indicated the incidence of FN was significantly lower in the group that received prophylactic antibiotics compared with the group that did not receive prophylactic antibiotics (P = 0.017). Compared with prophylactic G-CSF alone, prophylactic G-CSF and antibiotics significantly suppressed the occurrence of FN.

Summary Introduction: The prevalence of nosocomial fungemia has increased worldwide, and mortality caused by this disease is high. Objective: To assess progress in the last decade, and the prevalence and profile of fungal agents isolated in blood cultures performed in a tertiary university hospital. Method: All the results of blood cultures processed at Hospital das Clínicas, Universidade Federal de Minas Gerais (HC-UFMG), in the time intervals 2001-2003 and 2011-2013 were analyzed retrospectively. For each three-year period, the number of collected blood cultures, the overall positivity rate and the percentage of fungemia were recorded. In addition, all identified fungal species were cataloged. All blood samples were incubated in the BacT/ALERT® (bioMérieux) automation system. Results: In 2001-2003, 34,822 samples were evaluated, with 5,510 (15.8%) positive results. In 2011-2013, the number of blood cultures processed increased to 55,052 samples, with 4,873 (8.9%) positive results. There was an increase in the number of positive cultures for fungi in the analyzed period (2001-2003: 4.16%; 2011-2013: 5.95%; p<0.001). Among the agents, candidemias were predominant, especially those caused by non-albicans Candida species (2001-2003: 57.64%; 2011-2013: 65.17%; p<0.05). There was also an increase in fungemia caused by other genera (2001-2003: 2.62%; 2011-2013: 4.48%; p<0.01). Conclusion: There was an increase in the prevalence of fungemia in the last decade at HC-UFMG. Although candidemias have been responsible for most of the cases, there has been an increase in fungemias caused by other species.

A study was performed on 100 pregnant women in the outpatient department of gynecology and obstetrics of Maternity and Children Hospital in Al-Diwaniya City during the period between (March to September 2016). One hundred blood samples (50 for patients and 50 for control) were collected under the supervision of the treating gynecologist. The detection of Helicobacter. pylori was done by the use of the serum antibody Rapid test. The results showed that 50 (100%) were positive and 50 (100%) were negative for H. pylori in above method.All blood of patients and control samples were used for the extraction of genomic DNA,where the 107 bp PCR product size. Genotyping of the TNF-α-308 SNP (G/A)was performed by restriction fragment length polymorphism PCR (RFLP-PCR). PCR products were digested with restr NcoI iction enzyme. Individuals with the TNF-α-308(GG) homozygote produced digested DNA bands at 80,and 20 bp bp. A heterozygous genotype ofTNF-α-308 (GA)produced 107 bp,80 bp,and 20 bp bands. Individuals with the TNF-α-308 (AA) homozygote genotype had no amplicon digested and generated only one band of 107 bp. There was a significant difference in the frequency of the TNF-α-308(GG)genotype between H. pylori positive group and H. pylori negative group(72%,78% respectively). Also for GA genotype,there was a significant difference between H. pylori positive group and H. pylori negative group(24%,18% respectively). Concerning the frequency of the TNF-α-308 (AA)genotype between H. pylori positive group and H. pylori negative group,there was no significant difference between the two groups.

Abstract Background As opposed to Staphylococcus. aureus bacteremia, there are no guidelines to recommend repeating blood cultures in Gram-negative bacilli bacteremia (GNB). Several studies have questioned the utility of follow-up blood cultures (FUBCs) in GNB, but the impact of this practice on clinical outcomes is not fully understood. Our aim was to study the practice of obtaining FUBCs in GNB at our institution and to assess it’s impact on clinical outcomes. Methods We conducted a retrospective, single-center study of adult patients, ≥ 18 years of age admitted with GNB between January 2017 and December 2018. We aimed to compare clinical outcomes in those with and without FUBCs. Data collected included demographics, comorbidities, presumed source of bacteremia and need for intensive care unit (ICU) admission. Presence of fever, hypotension /shock and white blood cell (WBC) count on the day of FUBC was recorded. The primary objective was to compare 30-day mortality between the two groups. Secondary objectives were to compare differences in 30-day readmission rate, hospital length of stay (LOS) and duration of antibiotic treatment. Mean and standard deviation were used for continuous variables, frequency and proportion were used for categorical variables. P-value &lt; 0.05 was defined as statistically significant. Results 482 patients were included, and of these, 321 (67%) had FUBCs. 96% of FUBCs were negative and 2.8% had persistent bacteremia. There was no significant difference in 30-day mortality between those with and without FUBCs (2.9% and 2.7% respectively), or in 30-day readmission rate (21.4% and 23.4% respectively). In patients with FUBCs compared to those without FUBCs, hospital LOS was longer (7 days vs 5 days, P &lt; 0.001), and mean duration of antibiotic treatment was longer (14 days vs 11 days, P &lt; 0.001). A higher number of patients with FUBCs needed ICU care compared to those without FUBCs (41.4% and 25.5% respectively, P &lt; 0.001) Microbiology of index blood culture in those with and without FUBCs Outcomes in those with and without FUBCs FUBCs characteristics Conclusion Obtaining FUBCs in GNB had no impact on 30-day mortality or 30-day readmission rate. It was associated with longer LOS and antibiotic duration. Our findings suggest that FUBCs in GNB are low yield and may not be recommended in all patients. Prospective studies are needed to further examine the utility of this practice in GNB. Disclosures All Authors: No reported disclosures

OBJECTIVE: To investigate the clinical value of dynamic contrast enhanced ultrasound (D-CEUS) in predicting the microvascular invasion (MVI) of hepatocellular carcinoma (HCC). PATIENTS AND METHODS: In this retrospective study, 16 patients with surgery and histopathologically proved HCC lesions were included. Patients were classified according to the presence of MVI: MVI positive group (n = 6) and MVI negative group (n = 10). Contrast enhanced ultrasound (CEUS) examinations were performed within a week before surgery. Dynamic analysis was performed by VueBox ® software (Bracco, Italy). Three regions of interests (ROIs) were set in the center of HCC lesions, at the margin of HCC lesions and in the surrounding liver parenchyma accordingly. Time intensity curves (TICs) were generated and quantitative perfusion parameters including WiR (wash-in rate), WoR (wash-out rate), WiAUC (wash-in area under the curve), WoAUC (wash-out area under the curve) and WiPi (wash-in perfusion index) were obtained and analyzed. RESULTS: All of HCC lesions showed arterial hyperenhancement (100 %) and at the late phase as hypoenhancement (75 %) in CEUS. Among all CEUS quantitative parameters, the WiAUC and WoAUC were higher in MVI positive group than in MVI negative group in the center HCC lesions (P <  0.05), WiAUC, WoAUC and WiPI were higher in MVI positive group than in MVI negative group at the margin of HCC lesions. WiR and WoR were significant higher in MVI positive group. CONCLUSIONS: D-CEUS with quantitative perfusion analysis has potential clinical value in predicting the existence of MVI in HCC lesions.

Abstract Objective Hepatitis B surface antigen (HBsAg) is known as the hallmark of hepatitis B virus (HBV) infection. This study aimed to determine whether an HBsAg neutralization test is necessary to accurately interpret HBsAg test results. Methods Initially reactive HBsAg specimens from a 5-year period, with cutoff index values between 1.0 and 2.0, were subjected to neutralization confirmatory testing using an Elecsys HBsAg Confirmatory test kit (Roche Diagnostics GmbH. Mannheim, Germany). Results The neutralization test showed 46.1% positive (confirmed positive group) and 53.9% negative (confirmed negative group) results from the total specimens. Among the confirmed negative group, 79.5% of patients were confirmed to be negative for the current infection, whereas 4 patients in the chronic hepatitis B subgroup showed a neutralization percentage close to 40%. More than half of patients in the confirmed positive group were considered to be in the hepatitis B e antigen-negative inactive HBsAg carrier phase. Conclusion In populations with intermediate HBV prevalence, a neutralization test is necessary to confirm an HBsAg result and reduce the false positive and false negative rates of initial HBsAg tests.

AbstractThe effects of intravenous sedation with midazolam on the cerebral function of elderly patients with severe dementia are unclear. This study aimed to evaluate its effects on parameters such as brainwaves and cerebral blood flow (CBF) and compare them between elderly individuals with dementia and without cognitive impairment. Ten patients with severe dementia and 10 without cognitive impairment were registered. The bispectral index (BIS) and normalized tissue hemoglobin index (nTHI), which reflects CBF using near-infrared spectroscopy, were measured. Midazolam was administered until a Modified Observer’s Assessment of Alertness/Sedation score of 2 was reached. The chi-squared, Mann–Whitney U, Wilcoxon signed-rank, and Friedman tests and multiple regression analysis were used for comparisons. Whereas a similar decline in BIS values was observed in both groups after midazolam administration (P < 0.018), there was a significant decrease by 9% in the nTHI of the dementia-positive group (P < 0.013). However, there was no significant difference in the nTHI between the dementia-positive and dementia-negative group according to the multiple regression analysis (P = 0.058). In the dementia-negative group, none of the measured values differed from the baseline values. In the dementia-positive group, sedation with midazolam resulted in a 9% decrease in the CBF.
