IntroductionConcurrent Staphylococcus aureus bacteremia (SAB) worsens outcomes and increases mortality in patients with complicated skin and skin structure infections (cSSSI), hospital-acquired bacterial pneumonia, and ventilator-associated bacterial pneumonia (HABP/VABP). These challenges highlight the need for alternative treatments. Telavancin (TLV), a bactericidal lipoglycopeptide with high in vitro potency, effectively treats patients with cSSSI and HABP/VABP caused by Gram-positive pathogens, particularly S. aureus.MethodsThis retrospective analysis evaluated patients from the Assessment of Telavancin in Complicated Skin and Skin Structure Infections and Assessment of Telavancin for Treatment of Hospital-Acquired Pneumonia studies with baseline, concurrent SAB. Differences in the clinical cure rates at test-of-cure and safety outcomes were compared for TLV vs vancomycin (VAN) treatment groups.ResultsA total of 105 patients, 32 cSSSI and 73 HABP/VABP, had baseline, concurrent SAB. The clinical cure rates for all-treated SAB patients in the cSSSI (TLV 57.1% and VAN 54.5%) and HABP/VABP (TLV 54.3% and VAN 47.2%) groups were comparable. For both types of infections, the safety profile of TLV and VAN showed similar incidences of adverse events (AEs), serious AEs, or AEs leading to discontinuation. One VAN-treated patient died in the cSSSI group, and there were 13 deaths in each treatment arm of the HABP/VABP group.ConclusionThis retrospective analysis demonstrated that TLV is clinically comparable in both efficacy and safety to VAN, and, therefore, may be an appropriate therapeutic option for the treatment of patients with HABP/VABP or cSSSI and concurrent SAB. Given the limited sample size in this subgroup, the interpretation of these results is limited.FundingTheravance Biopharma Antibiotics, Inc.

Concurrent bacteremia in patients with dengue fever is rarely reported. Two and a half-year-old female child with fever, cough and cold for six days presented to Emergency Room (ER) with tachypnea, tachycardia and hepatomegaly. Investigations revealed dengue fever. Respiratory symptoms probed us to investigate the case further. High-Resolution Computed Tomography (HRCT) thorax showed moderate pleural effusion with collapse consolidation of left lung and a thin walled cavity with septations and fluid in left upper lobe. Child was treated with injection meropenem and vancomycin successfully.

Background/Purpose: Bacteremia in dengue may occur with common exposure to pathogens in association with severe organ impairment or severe dengue, which may result in death. Cohort studies identifying risk factors for concurrent bacteremia among patients with dengue are rare. Methods: We conducted a retrospective case–control study of adult patients with dengue who were admitted to the Department of Infectious Diseases at Tan Tock Seng Hospital, Singapore from 2004 to 2008. For each case of dengue with concurrent bacteremia (within the first 72 hours of admission), we selected four controls without bacteremia, who were matched on year of infection and dengue confirmation method. Conditional logistic regression was performed to identify risk factors for concurrent bacteremia. Results: Among 9,553 patients with dengue, 29 (0.3%) had bacteremia. Eighteen of these patients (62.1%) had concurrent bacteremia. The predominant bacteria were Staphylococcus aureus, one of which was a methicillin-resistant strain. Dengue shock syndrome occurred more frequently and hospital stay was longer among cases than among controls. Three cases did not survive, whereas none of the controls died. In multivariate analysis, being critically ill at hospital presentation was independently associated with 15 times the likelihood of a patient with dengue having concurrent bacteremia. Conclusion: Concurrent bacteremia in adult patients with dengue is uncommon but presents atypically and results in more deaths and longer hospital stay. Given the associated mortality, collection of blood cultures and empiric antibiotic therapy may be considered in patients who are critically ill.
