Bordetella bronchiseptica is a well-described pathogen classically causing respiratory infections in household pets. We describe a case of postsurgical meningitis in an adult patient. A 49-year -old man with a recently resected glioblastoma developed altered mental status approximately 2 weeks after surgery and was found to have B bronchiseptica meningitis. B bronchiseptica is a very rare cause of meningitis. It has only been described twice before in the literature, both in pediatric patients. It should be considered in patients with household pets. It can be a particularly virulent organism given its ability to form biofilms. In our case, the patient failed initial treatment with 2 weeks of meropenem and required re-treatment.

237 Background: HCC is a highly vascularized tumor, and inhibition of angiogenesis by sorafenib (Sor)—a VEGFR and PDGFR inhibitor—delays tumor progression. However, angiogenic escape from Sor may result from activation of the FGFR pathway, which also plays an important role in angiogenesis. Dovitinib (Dov) inhibits FGFR as well as VEGFR and PDGFR. Here, we study frontline Dov vs Sor in pts with advanced HCC. Methods: Eligible pts in this open-label study had ≥ 1 measurable lesion at baseline. All pts were ineligible for or had disease progression after surgical and/or locoregional therapies. Prior systemic HCC therapy was not allowed. Pts were randomized to receive Dov (500 mg/day, 5 days on/2 days off) or Sor (400 mg twice daily) until disease progression, unacceptable toxicity, or death. No treatment crossover was allowed. The primary endpoint was overall survival (OS). The key secondary endpoint was time to tumor progression (TTP) by local investigator’s assessment (per RECIST v1.1). Results: Pts received Dov (n = 82) or Sor (n = 83). Most pts—43 (52.4%) in the Dov arm and 60 (72.3%) in the Sor arm—discontinued treatment due to progressive disease. Median OS (95% CI) was 34.6 wk (28.6-39.4 wk) for Dov and 36.7 wk (23.3-49.3 wk) for Sor; Kaplan-Meier HR, 1.27; 95% CI, 0.89-1.80. Median TTP (95% CI) was 17.6 wk (12.3-18.4 wk) and 17.9 wk (12.3-18.9 wk), respectively. In pts who received ≥ 1 dose of study drug, median duration of exposure was 2.5 mo for Dov (n = 79) and 3.2 mo for Sor (n = 83). The most common adverse events, regardless of cause, were diarrhea (62.0%), decreased appetite (43.0%), nausea and vomiting (40.5% each), fatigue (35.4%), rash (34.2%), and pyrexia (30.4%) in the Dov arm and palmar-plantar erythrodysesthesia syndrome (66.3%), diarrhea (42.2%), and decreased appetite (31.3%) in the Sor arm. VEGFR1 and HGF baseline plasma levels appear to be associated with OS only in the Dov arm. Median OS in the lower biomarker group for both VEGFR1 and HGF was 11 mo while it was 5.6 and 5.9 mo for VEGFR1 and HGF, respectively, in the higher biomarker group. Conclusions: Activity of Dov was not greater than that of Sor in frontline HCC. The safety profile was similar to that observed in other single-agent Dov trials.

We suggest that people living with HIV (PLWH) may serve as pre-exposure prophylaxis (PrEP) educators for partners when informed about PrEP. Participants in this study were a convenience sample of PLWH at a public hospital in Miami. A cross-sectional survey assessed the frequency of serostatus disclosure, PrEP awareness, and willingness to recommend PrEP to intimate partners. To evaluate stigma surrounding human immunodeficiency virus (HIV), comfort discussing HIV with family, friends and intimate partners was interrogated. Surveys were completed by 137 participants; 39.5% had potentially sero-discordant sexual partners. Among respondents, 29.2% reported that they ‘occasionally’ or ‘never’ disclose HIV status to sexual partners. In all, 66.4% of patients reported that they had never heard of PrEP. After being educated about PrEP, 86.0% of respondents reported that they would encourage partners to use it. Participants were asked how often the subject of HIV comes up in conversations. Most indicated that ‘rarely’ or ‘never’ does it come up with friends and family; 46.1% indicated that ‘never’ or ‘rarely’ does it come up with partners. In bivariate analyses, participants with prior awareness of PrEP were more likely to indicate higher frequency of conversations regarding HIV with intimate partners. It is concluded that interventions which utilize partner education to increase PrEP uptake should address stigma and knowledge among other barriers.
