Objectives: Insufficient linezolid levels, which are associated with a poorer outcome, are often observed in ICU patients who receive standard dosing. Although strategies to overcome these insufficient levels have been discussed, appropriate alternative dosing regimens remain to be identified. Methods: Various infusion regimens (1200-3600 mg/day; q6h, q8h, q12h and continuous) were simulated in 67 000 ICU patients. The probability of attaining pharmacodynamic targets ( T >MIC ≥85%, AUC/MIC ≥100, cumulative fraction of response for Staphylococcus aureus and Enterococcus spp...

BACKGROUND: Ventilator associated pneumonia (VAP) is one of the most serious nosocomial infections in Intensive Care Unit (ICU). The aim of this study was to evaluate a new approach to spare the carbapenems for the management of patients diagnosed with VAP due to Acinetobacter baumannii (A. baumannii). METHOD: This retrospective study was conducted on VAP patients presenting for treatment at tertiary care centre between May 2014 and March 2016. The case sheets of patients who have been treated for VAP with meropenem, antibiotic adjuvant entity (AAE) and colistin were analysed...

Raj Shah, Danielle Witt, Talal Asif, Fahad F Mir
Ipilimumab is a human monoclonal antibody that functions as a cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitor that is used to treat malignant melanoma. Due to ipilimumab's removal of immune regulation, specifically through the inactivation of CTLA-4, it is commonly associated with inflammatory and autoimmune events. Gastrointestinal (GI) related immune-related adverse events such as diarrhea occur in 29% of patients with 7.6% of patients specifically suffering from colitis. We describe a case of colonic perforation with ipilimumab use...

BACKGROUND: Due to the vulnerable nature of its patients, the wide use of invasive devices and broad-spectrum antimicrobials used, the intensive care unit (ICU) is often called the epicentre of infections. In the present study, we quantified the burden of hospital acquired pathology in a Romanian university hospital ICU, represented by antimicrobial agents consumption, costs and local resistance patterns, in order to identify multimodal interventional strategies. METHODS: Between 1(st) January 2012 and 31(st) December 2013, a prospective study was conducted in the largest ICU of Western Romania...

OBJECTIVES: The adequate perioperative antibiotic prophylaxis in head and neck cancer surgery is an important and easy applicable tool to decrease nosocomial morbidity and mortality by reducing the rate of infections. In the study a strictly perioperative antibiosis is compared with an extended postoperative prophylactic antibiosis. We aim to clarify the value of postoperative prophylactic antibiosis for the recovery and clinical course of patients. MATERIAL AND METHODS: In this prospective study 75 consecutive patients, who underwent major oncological head and neck surgery were included and divided in three groups, each containing 25 patients...

Optimal dosing of β-lactam antibiotics in critically ill patients is a challenge given the unpredictable pharmacokinetic profile of this patient population. Several studies have shown intermittent dosing to often yield inadequate drug concentrations. Continuous dosing is an attractive alternative from a pharmacodynamic point of view. This study evaluated whether, during continuous dosing, piperacillin concentrations reached and maintained a pre-defined target in critically ill patients. Adult patients treated with piperacillin by continuous dosing in the intensive care unit of a university medical centre in The Netherlands were prospectively studied...

PURPOSE: Hospital-acquired pneumonia (HAP) remains one of the major hospital-acquired infections in China. Antibiotic treatment of HAP may lead to subsequent Clostridium difficile infection (CDI). Baseline data on the occurrence of CDI among HAP patients in China are currently unavailable. This study examines the risk and disease burden of CDI among HAP hospitalized patients (HAP-CDI). METHODS: We conducted a prospective study among ICU patients with HAP and hospital-onset diarrhea from January 2014 to December 2014 in a teaching hospital in China...

BACKGROUND: Aerosolized amikacin (AA) is a current option for the management of ventilator-associated pneumonia (VAP) caused by multidrug-resistant Gram-negative bacteria (MDR-GNB), as it is reported that AA could increase the alveolar level of the drug without increasing systemic toxicity. This study aimed to evaluate the efficacy and safety of AA as an adjunctive therapy for VAP caused by MDR-GNB. METHODS: In this single-center, double-blind study conducted in a 36-bed general Intensive Care Unit (ICU) in a tertiary hospital from June 2014 to June 2016, 52 ICU patients with confirmed MDR-GNB VAP were randomized to two groups (AA group, n = 27 and placebo group, n = 25)...

REVIEW
J T Kielstein, A K Kruse, N Anderson, H Vaitiekunas, S Scherneck
We would neither be disappointed nor upset if the gas mileage on the sticker of a car didn't match our personal, real-life fuel consumption. Depending on our daily route to work, our style of accelerating and the number of passengers in our carpool, the gas mileage will vary. As soon as the falcon wing door of our car is closed and entrance to the ICU is granted, we tend to forget all of this, even though another hot rod is waiting there for us. Renal replacement therapy is like a car; it fulfills goals, such as the removal of uremic toxins and accumulated fluids, but it also "consumes" (removes) antibiotics...

BACKGROUND: Necrotizing fasciitis is a life-threatening soft tissue infection characterized by a rapid spreading infection of the subcutaneous tissue and in particular the fascia. The management of infected tissues requires a rapid diagnosis, immediate aggressive surgical management and an extended debridement. In some cases early amputations of the affected tissues and maximum intensive care treatment, in case of sepsis, are required. Due to a rising number of cases we aimed to evaluate our patients in a retrospective review...

BACKGROUND: Procalcitonin (PCT) is a prohormone that rises in bacterial pneumonia and has promise in reducing antibiotic use. Despite these attributes, there are inconclusive data on its use for clinical prognostication. We hypothesize that serial PCT measurements can predict mortality, intensive care unit (ICU) admission, and bacteremia. METHODS: A prospective cohort study of inpatients diagnosed with pneumonia was performed at a large tertiary care center in Boston, Massachusetts...

Critically ill patients need fast, effective and safe pharmacotherapy. The pharmacokinetics and pharmacodynamics of the administered drugs are influenced by numerous individual conditions. Genetic factors mainly determines drug metabolism. However, therapeutic decisions are not yet guided by genetic analyses. In elderly patients, the volume of distribution can be altered and renal elimination may be delayed. Drug-drug interactions involving current medications can increase the incidence of adverse effects from treatment in the intensive care unit...

A surveillance study was conducted at a University Hospital in Buenos Aires City aimed to assess the rates of colonization with carbapenemase-producing strains of Klebsiella pneumoniae, which are bacteria of utmost epidemiological importance. To this end, rectal swabs collected from all inpatients were cultured for the presence of these bacteria. Two point prevalence surveys showed high prevalence rates (up to 25%). The following variables were evaluated in all inpatients: place of origin (home or other chronic care center), age, prolonged hospitalization, antibiotics for at least 72 hours prior to swabbing, intensive care unit requirements for at least 24 hours, mechanical ventilation assistance for more than 4 days, hemodialysis requirements, need for surgery, enteral feeding through a nasogastric tube, and functional evaluation according to the Karnofsky performance scale...

BACKGROUND: We hypothesized that patients undergoing surgery for colorectal cancer (CRC) with COPD as a comorbidity would consume more resources and have worse in-hospital outcomes than similar patients without COPD. Therefore, we compared different aspects of the care process and short-term outcomes in patients undergoing surgery for CRC, with and without COPD. METHODS: This was a prospective study and it included patients from 22 hospitals located in Spain - 472 patients with COPD and 2,276 patients without COPD undergoing surgery for CRC...
