AbstractPrior to offering the hepatitis B (HB) vaccine, a prescreen for hepatitis B virus (HBV) antibodies was conducted in a 565 bed hospital in Pasadena, California. Antibodies to the hepatitis B virus were detected in 14.5% of 1,745 employees tested. There was a significantly higher prevalence in those with a previous history of hepatitis, blood transfusions, exposure to nee-dlesticks, number of years in the same occupation, and in the same hospital work area. Employees of Asian extraction (33.3%) and blacks (23.1%) had a higher prevalence of antibodies to the hepatitis B virus than Hispanics (13.7%) and whites (10.2%). Anti-HBs was detected in 92.6% of 865 employees who received three doses of the hepatitis B vaccine. Only 28.6% of nonresponders receiving a fourth dose of hepatitis B vaccine produced anti-HBs. The nonresponders to the HB vaccine were older (average age 64.9 years) when compared to the responders (average age 37.5 years), and more males failed to produce anti-HBs after vaccination than females. Hepatitis B vaccination of the majority of individuals with either “low level” anti-HBs alone or anti-HBc alone did not elicit an anamnestic response after one dose of vaccine, implying that these “low level” antibodies are nonspecific and do not represent antiviral antibodies. Adverse reactions to the hepatitis B vaccine were minor and included a flulike syndrome, sore arm, and rash and swelling at the injection site. The reasons for nonparticipation were obtained from 179 individuals, and the main issue was concern about safety of the hepatitis B vaccine.

Background. The World Health Organization has recommended pilot implementation of a candidate vaccine against malaria (RTS,S/AS01) in selected sub-Saharan African countries. This exploratory study aimed to estimate the costs of implementing RTS,S in Burkina Faso, Ghana, Kenya, Mozambique, and Tanzania. Methods. Key informants of the expanded program on immunization at all levels in each country were interviewed on the resources required for implementing RTS,S for routine vaccination. Unit prices were derived from the same sources or from international price lists. Incremental costs in 2015 US dollars were aggregated per fully vaccinated child (FVC). It was assumed the four vaccine doses were either all delivered at health facilities or the fourth dose was delivered in an outreach setting. Results. The costs per FVC ranged from US$25 (Burkina Faso) to US$37 (Kenya) assuming a vaccine price of US$5 per dose. Across countries, recurrent costs represented the largest share dominated by vaccines (including wastage) and supply costs. Non-recurrent costs varied substantially across countries, mainly because of differences in needs for hiring personnel, in wages, in cold-room space, and equipment. Recent vaccine introductions in the countries may have had an impact on resource availability for a new vaccine implementation. Delivering the fourth dose in outreach settings raised the costs, mostly fuel, per FVC by less than US$1 regardless of the country. Conclusions. This study provides relevant information for donors and decision makers about the cost of implementing RTS,S. Variations within and across countries are important and the unknown future price per dose and wastage rate for this candidate vaccine adds substantially to the uncertainty about the actual costs of implementation.

Meningococcal serogroup B vaccine 4CMenB (Bexsero) is a new four-component protein vaccine developed to prevent Neisseria meningitidis serogroup B infections. Case. We report a girl with fever and supraventricular tachycardia (SVT) 6–8 hours after the second dose of 4CMenB. SVT was unresponsive to the first dose of adenosine but terminated after the fourth dose of adenosine. During three months of follow-up, she was free of further SVT attacks. Conclusion. This is the first report of ECG-proven SVT after 4CMenB vaccination. Even if fever is coexistent, SVT should be considered after persistent tachycardia and 4CMenB vaccination.

Background and objectives: Achieving vancomycin therapeutic levels is essential for antibacterial success and resistance prevention. Multiple studies have shown that most of the children fail to reach therapeutic trough levels (10–20 µg/mL). This study aims to determine the frequency of achieving therapeutic vancomycin initial trough levels in children, evaluate the effect of age on that achievement and the mean initial trough levels, and the frequency of supratherapeutic levels. Methods: Children aged 1 month to 12 years who received three or more vancomycin doses 15 mg/kg every 6 h while admitted at our hospital from February 2016 to January 2017, and had a level before the fourth dose were included. Cases with high baseline serum creatinine, acute kidney injury, and congenital heart disease were excluded. Results: Out of 75 included cases, one third, 28/75 (37.3%), achieved goal. The lowest frequency was 6/28 (21.4%) of the 2–5 years group, which were statistically less likely to achieve, and had significantly lower mean initial trough than the 1–23 months group ( P = 0.026 and 0.013, respectively). Mean initial trough levels were 10.1, 7.3, and 8.2 µg/mL in the 1–23 months, 2–5 years, and 6–12 years groups, respectively ( P = 0.014). No supratherapeutic levels were observed. Conclusion: Vancomycin dose of 60 mg/kg/day is insufficient to attain target levels for most of the children. Children aged 2–5 years are the least likely to achieve and have the lowest mean levels. More intensified doses are warranted to be studied prospectively to identify the most effective empiric dose for children.

Fourth Dose

Mitoxantrone is a recently appro ved drug for patients with secondary progressive multiple sclerosis (SPMS). However, cardiac side effects limit Mitoxantrone use in SPMS and its lifetime cumulative dose should not exceed 140 mg/m2. A dditionally, Mitoxantrone is contraindicated for use in SPMS patients with a baseline left ventricular ejectio n fraction (LVEF) of-50%. The goal of this study was to monitor LVEF more frequently than ordinarily recommended since experience with Mitoxantrone use in SPMS patients is limited. A n unexpected decline in LVEF in one of the SPMS patients being treated with Mitoxantrone prompted further investigation into this finding. In our clinic, 47 patients on Mitoxantrone were followed prospectively; 28 of 47 patients had received a minimum of three doses and underwent a repeat LVEF evaluation prior to their fourth dose of Mitoxantrone. O f these 28 patients, five of 28 (17.8%) had a significant decline in LVEF from baseline. It is suggested that more stringent cardiac monitoring guidelines than current Food and Drug A dministration (FDA) recommendations be used to avert potential cardiac complications in SPMS patients on Mitoxantrone.

1080 Background: Aminophospholipid are normally expressed on damaged or apoptotic cells, as well as on the intravascular surface of EC of vessels feeding the tumor as a result of the tumor microenvironment (e.g., hypoxia, reactive oxygen species). Bavituximab (B), a novel monoclonal antibody against PS, has demonstrated preclinical anti-tumor activity by eliciting both innate and adaptive immune responses specific to tumor vasculature. Here we report preliminary results of the phase I study in patients (pts) with advanced solid tumors. Methods: This is a phase I, dose escalation, safety, tolerability and pharmacokinetic (PK) study, as well as to define DLT, MTD and/or maximum effective dose (MED) in pts with advanced refractory cancers. Planned cohorts of 6 pts, each were to receive 0.1, 0.3, 1 or 3 mg/kg. Escalation was permitted if mean cohort Cmax ≤ 65 mcg/mL and dose limiting toxicities (DLT) was observed in ≤ 1 of 6 pts. No premedication was planned or needed. DLT was defined as ≥ grade 3 drug-related adverse events (AE), ≥ grade 2 PT, or ≥ grade 3 aPTT. B was given as a 90 minute IV infusion (on days 0, 28, 35, 42 for the first two dose cohorts and 0, 7, 14, 21 for the third- and fourth-dose cohorts. Although not a study endpoint, tumor response was collected at day 56. Results: Data are available for the first 20 pts enrolled (10 breast, 3 colorectal, 2 pancreatic, 1 each of hepatocellular carcinoma, head and neck, melanoma, mesothelioma, and prostate cancer). Cohorts by dose: 0.1 mg/kg (8 pts), 0.3 mg/kg (6pts), and 1 mg/kg (6pts). Median age was 59 years and 70% of pts were females. (Q: see attached Excel file). No DLTs or drug-related severe AEs were reported. Common drug-related AEs were fatigue (7pts), nausea (6 pts), dry skin (3 pts), constipation (2 pts) and dyspnea (2 pts). All AEs were grade 1 or 2 and no dose relationship was observed. PK was dose proportional with mean serum Cmax of 2.3, 5.2 and 16.6 mcg/mL for the 0.1, 0.3 and 1 mg/kg groups, respectively. No accumulation of B was seen after multiple weekly dosing. Conclusions: Single agent bavituximab is well tolerated to date, with a predictable PK profile. Accrual of the last planned cohort is underway. MTD has not been reached. Final results will be available for presentation at the time of the Meeting. [Table: see text]
