We report the case of a 61-year-old female with Crohn’s disease dependent on total parenteral nutrition who developed a central venous catheter bloodstream infection and septic arthritis, complicated further by osteomyelitis and persistent Candida glabrata fungemia. Fluconazole treatment led to persistent infection, and micafungin therapy failed with development of FKS-associated resistance. Infection responded after initiation of amphotericin B plus voriconazole. Echinocandin resistance is increasingly recognized, suggesting a role for alternative antifungal therapies.

Objectives To date, clinical trials evaluating baloxavir have excluded patients hospitalized with influenza infection and therefore this study sought to evaluate the efficacy of baloxavir in inpatients with influenza A. Methods This study was a multicentre, retrospective chart review of adult patients admitted to the hospital within the Yale New Haven Health System who received oseltamivir or baloxavir for the treatment of influenza A. Patients were screened for inclusion between January 2018 and April 2018 in the oseltamivir group, while patients in the baloxavir group were screened for inclusion between January 2019 and April 2019. Influenza A diagnosis was confirmed by RT–PCR using a nasopharyngeal swab specimen. Results Of the 2392 patients assessed, 790 met the inclusion criteria. There were 359 patients who received baloxavir and 431 patients who received oseltamivir. Patients who received baloxavir were younger compared with those who received oseltamivir [median = 69 (IQR = 57–81) years versus 77 (IQR = 62–86) years; P < 0.001]. Patients who received baloxavir had no significant difference in hospital length of stay [median = 4 (IQR = 3–6) days versus 5 (IQR = 3–6)  days; P = 0.45] or 30 day all-cause mortality [12 (3.3%) versus 26 (6%); P = 0.079] compared with those who received oseltamivir. However, patients who received baloxavir had a significantly faster time to hypoxia resolution [median = 51.7 (IQR = 25.3–89.3) h versus 72 (IQR = 37.5–123) h; P < 0.001]. Conclusions The results of this study support the use of baloxavir for the treatment of influenza A in hospitalized patients with the potential benefit of a faster time to resolution of hypoxia.

Gastrointestinal intolerance has been associated with ritonavir-boosted protease inhibitors. This post hoc analysis evaluated gastrointestinal adverse events of interest (AEOIs; diarrhea, nausea, abdominal discomfort, flatulence [MedDRAv21]) through Wk96 among patients enrolled in the phase 3 AMBER (treatment-naïve) and EMERALD (virologically suppressed) studies of darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) 800/150/200/10 mg. 362 and 763 patients initiated D/C/F/TAF in AMBER and EMERALD, respectively. All D/C/F/TAF-related gastrointestinal AEOIs were grade 1/2 in severity; none were serious. Across studies, incidence of D/C/F/TAF-related diarrhea and nausea were each ≤5% in Wk1 (≤1% post-Wk2); prevalence of each decreased to <5% post-Wk2. In each study, there was 1 case of D/C/F/TAF-related abdominal discomfort during Wk1 and none thereafter. Incidence of D/C/F/TAF-related flatulence was <1% throughout. Median duration of D/C/F/TAF-related gastrointestinal AEOIs was 16.5 (AMBER) and 8.5 (EMERALD) days. In conclusion, in treatment-naïve and virologically suppressed patients, incidences and prevalences of D/C/F/TAF-related gastrointestinal AEOIs were low and tended to present early.

Background Ritonavir boosted protease inhibitors have been associated with GI intolerance. A post hoc analysis was conducted to assess the GI profile of D/C/F/TAF in treatment naïve patients. Methods The phase 3 AMBER trial (ClinicalTrials.gov: NCT02431247) enrolled treatment naïve patients randomized 1:1 to receive once daily D/C/F/TAF 800/150/200/10 mg or D/C + F/tenofovir disoproxil fumarate (TDF). This post hoc analysis evaluated the incidence, prevalence and duration of GI adverse events of interest (AEOIs) through Wk 96. Related GI AEOIs were defined as diarrhea, nausea, abdominal pain and flatulence (by preferred term using MedDRAv21) deemed very likely, probable, or possibly related to study drug by the investigator. Incidence and prevalence were examined at weekly intervals during the first month of treatment and monthly thereafter. Duration of an AE was calculated for patients whose AEs had start and stop dates. Results In AMBER (N = 725), 362 patients were randomized to D/C/F/TAF and 363 to D/C + F/TDF (Table). Through Wk 48, 14% of D/C/F/TAF patients had a study drug–related GI AEOI vs 19% of D/C + F/TDF patients; of these, all were grade 1/2 and none were serious. Incidence and prevalence of D/C/F/TAF-related GI AEOIs remained low through 96 wks (Figure 1 & 2). Incidence of D/C/F/TAF-related diarrhea and nausea were each 5% in Wk 1 and ≤1% after Wk 2; prevalence of each decreased to &lt; 5% at Wk 2. There was 1 case of D/C/F/TAF-related abdominal discomfort at Wk 1 and none thereafter. Incidence of D/C/F/TAF-related flatulence was &lt; 1% from Wk 1 through Wk 96. Only 2 (1%) patients discontinued before Wk 96 due to a D/C/F/TAF-related GI AEOI (both diarrhea). Through Wk 96, &lt; 3% of patients required treatment with concomitant medication for a D/C/F/TAF-related GI AEOI. Among patients with a D/C/F/TAF-related GI AEOI, the median duration was 16.5 days. Conclusion In AMBER, incidences and prevalences of D/C/F/TAF-related GI AEOIs were low and tended to present early in the study. Combined with rapid decreases in prevalence, these finding suggest that GI AEOIs were transient. Overall, the GI profile of D/C/F/TAF was favorable, and to a greater extent than D/C + F/TDF, suggesting improved tolerance vs an older formulation. Table.
