Over the last 25 years, the terminology of skin and soft tissue infections, as well as their classification for optimal management of patients, has changed. The so-called and recently introduced term 'acute bacterial skin and skin structure infections' (ABSSSIs), a cluster of fairly common types of infection, including abscesses, cellulitis, and wound infections, require an immediate effective antibacterial treatment as part of a timely and cautious management. The extreme level of resistance globally to many antibiotic drugs in the prevalent causative pathogens, the presence of risk factors of treatment failure, and the high epidemic of comorbidities (e.g. diabetes and obesity) make the appropriate selection of the antibiotic for physicians highly challenging. The selection of antibiotics is primarily empirical for ABSSSI patients which subsequently can be adjusted based on culture results, although rarely available in outpatient management. There is substantial evidence suggesting that inappropriate antibiotic treatment is given to approximately 20-25% of patients, potentially prolonging their hospital stay and increasing the risk of morbidity and mortality. The current review paper discusses the concerns related to the management of ABSSSI and the patient types who are most vulnerable to poor outcomes. It also highlights the key management time-points that treating physicians and surgeons must be aware of in order to achieve clinical success and to discharge patients from the hospital as early as possible.
Acute bacterial skin and skin structure infections are caused mainly by Gram-positive bacteria which are often treated with intravenous vancomycin, daptomycin, or linezolid, with potential step down to oral linezolid for outpatients. Tedizolid phosphate 200mg once daily treatment for six days demonstrated non-inferior efficacy, with a favourable safety profile, compared with linezolid 600mg twice daily treatment for 10 days in the Phase 3 ESTABLISH-1 and -2 trials. The objective of the current post-hoc analysis of the integrated dataset of ESTABLISH-1 and -2 was to evaluate the efficacy and safety of tedizolid (N=182) vs linezolid (N=171) in patients of Latino origin enrolled into these trials. The baseline demographic characteristics of Latino patients were similar between the two treatment groups. Tedizolid demonstrated comparable efficacy to linezolid at 48-72h in the intent-to-treat population (tedizolid: 80.2% vs linezolid: 81.9%). Sustained clinical success rates were comparable between tedizolid- and linezolid-treated Latino patients at end-of-therapy (tedizolid: 86.8% vs linezolid: 88.9%). Tedizolid phosphate treatment was well tolerated by Latino patients in the safety population with lower abnormal platelet counts at end-of-therapy (tedizolid: 3.4% vs linezolid: 11.3%, p=0.0120) and lower incidence of gastrointestinal adverse events (tedizolid: 16.5% vs linezolid: 23.5%). Population pharmacokinetic analysis suggested that estimated tedizolid exposure measures in Latino patients vs non-Latino patients were similar. These findings demonstrate that tedizolid phosphate 200mg, once daily treatment for six days was efficacious and well tolerated by patients of Latino origin, without warranting dose adjustment.
BackgroundHerpes zoster (HZ) has a significant negative effect on the productive work life of individuals, and has been shown to be responsible for cases of absenteeism, presenteeism and decreased work effectiveness. The aim of this study was to evaluate health utility scores and associated predictors in an actively employed population of Herpes Zoster (HZ) patients with and without work time loss (WTL).MethodsThis was a pooled analysis of the prospective, observational MASTER cohort studies, conducted in 8 countries across North America, Latin America and Asia. A total of 428 HZ patients engaged in full or part time work were included. WTL, defined as missing ≥ 1 partial or full work day, and work effectiveness, reported on a scale of 0–100%, were evaluated with the Work and Productivity Questionnaire (WPQ). The Pearson product–moment correlation was used to assess the correlation between work effectiveness and HRQoL. Mixed models with repeated measures assessed the relationship between HZ-related WTL over a 6-month follow-up period, and HRQoL, as evaluated by the EQ-5D. Additional predictors of HRQoL were also identified.ResultsOverall, 57.7% of respondents reported WTL. Mean (SD) percent work effectiveness of patients in the WTL group was significantly lower compared to non-WTL (NWTL) patients at baseline [50.3 (31.6) vs. 71.4 (27.8); p < 0.001]. Patients in the WTL group also reported lower health utility scores at baseline and overall than their NWTL counterparts, with WTL identified as an independent negative predictor of both the EQ-5D summary scores and the EQ-5D VAS (p < 0.001). Decrease in work effectiveness was negatively associated with HRQoL overall (p < 0.001). Predictors of lower HRQoL were worst Zoster Brief Pain Inventory (ZBPI) pain score, the presence of HZ complications and country income (predictor of EQ-5D VAS only).ConclusionsHZ adversely impacts the work and productive life of actively employed individuals. In turn, HZ-related reductions in work effectiveness and work time are associated with a negative effect on HRQoL.Electronic supplementary materialThe online version of this article (doi:10.1186/s12955-017-0588-x) contains supplementary material, which is available to authorized users.
Objectives: To evaluate health utility scores and associated predictors in an actively employed population of Herpes Zoster (HZ) patients with and without work time loss (WTL). MethOds: Pooled analysis of the prospective, observational MASTER cohort studies, conducted in 8 countries across North America, Latin America and Asia. A total of 428 HZ patients engaged in full or part time work were included. WTL, defined as missing ≥ 1 partial or full work day, and job effectiveness, reported on a scale of 0-100%, were evaluated with the Work and Productivity Questionnaire (WPQ). The Pearson product-moment correlation was used to assess the correlation between job effectiveness and Health Related Quality of Life (HRQoL). Mixed models with repeated measures assessed the relationship between HZ-related WTL over a 6-month follow-up period, and HRQoL, as evaluated by the EQ-5D. Additional predictors of HRQoL were also identified. Results: Overall, 57.7% of respondents reported WTL. Mean (SD) percent job effectiveness of patients in the WTL group was significantly lower compared to non-WTL (NWTL) patients at baseline [50.3 (31.6) vs. 71.4 (27.8); p < 0.001]. Patients in the WTL group also reported lower health utility scores at baseline and overall than their NWTL counterparts, with WTL identified as an independent negative predictor of both the EQ-5D summary scores and the EQ-5D VAS (p < 0.001). Decrease in job effectiveness was negatively associated with HRQoL overall (p < 0.001). Predictors of lower HRQoL were worst ZBPI pain score category, the presence of HZ complications and country income category (predictor of EQ-5D VAS only). cOnclusiOns: HZ adversely impacts the work and productive life of actively employed individuals. In turn, HZ-related reductions in job effectiveness and work time are associated with a negative effect on HRQoL.
