Argatroban for suspected heparin-induced thrombocytopenia: contemporary experience at a large teaching hospital.
Heparin-induced thrombocytopenia requires immediate alternative anticoagulation to prevent or treat thromboembolic complications. Argatroban was approved based on multiple-center studies from the 1990s, but subsequent changes in prevailing awareness, diagnostic testing and therapeutic strategies for heparin-induced thrombocytopenia might affect results of argatroban therapy. Charts were retrospectively reviewed from patients administered argatroban for suspected heparin-induced thrombocytopenia over 22 months at a single large university hospital. ⋯ New thromboses (14.8%), progression of preexisting thromboses (0%), amputation secondary to heparin-induced thrombocytopenia (0%), death (22.2%), bleeding requiring transfusion (3.7%), and any bleeding (22.2%) compared favorably with older multiple-center reports. Deaths occurred mainly with preexisting multiple-organ failure. In contemporary "real world" use, argatroban provides safe and effective anticoagulation, strengthening the mandate to initiate alternative anticoagulation whenever heparin-induced thrombocytopenia appears likely.

Outcome of critically ill human immunodeficiency virus-infected patients in the era of highly active antiretroviral therapy.
The purpose of this study was to determine the effect of prior use of highly active antiretroviral therapy (HAART) on outcome of human immunodeficiency virus (HIV)- patients admitted to intensive care units (ICUs). This study was a retrospective chart review of 242 HIV-infected patients who required 259 consecutive admissions to a university-affiliated hospital ICU during a 3-year period. Patient demographics, CD4 count, admission diagnosis, prior HAART, Pneumocystis jiroveci prophylaxis, length of stay, and ICU and hospital mortality were determined. ⋯ Comparing patients who had received HAART before an ICU admission to those who had not, we found no difference between ICU or hospital mortality, need of mechanical ventilation, ICU and hospital length of stay, and incidence of P jiroveci. Pulmonary diagnosis was the most frequent ICU admission diagnosis (30%). Logistic regression analysis showed HIV-related illness and mechanical ventilation were significant independent predictors of increased hospital mortality.

Serum troponin I (TnI) is a sensitive marker of cardiac injury. A relation between elevated TnI and mortality has been suggested. In this retrospective chart review of 221 patients admitted to the medical intensive care unit (MICU) during a 6-month period, the authors studied the use of admission TnI levels in predicting mortality in MICU-admitted patients. ⋯ Positive TnI showed a weak association with intensive care unit (ICU) mortality (P = .049) but not with overall mortality. There was no significant correlation between admission TnI concentration and APACHE II score (P = .33), administration of vasopressor medications (P = .115), or development of multiorgan failure (P = .64). The authors concluded that there is no benefit in obtaining a routine admission troponin level in MICU patients when an acute coronary event is not suspected.

Drotrecogin alfa (activated) in sepsis: initial experience with patient selection, cost, and clinical outcomes.
During a 1-year period, the authors examined clinical experience with drotrecogin alfa, activated for sepsis in a 24-bed medical-surgical intensive care unit. Drotrecogin alfa, activated was administered 46 times to 44 patients (3% of all intensive care unit admissions). Eighty-six percent of patients were on vasopressors; 95% were mechanically ventilated. ⋯ The 28-day all-cause mortality was 36.4% and hospital mortality was 43.2%, trending higher (P = .10) than in the PROWESS study, which can be attributed to clinical use in patients who would not have met PROWESS study inclusion criteria. Failure to complete a 96-hour infusion of drotrecogin alfa, activated and transfer from another hospital or nursing home before treatment were associated with poor outcome. Total cost of hospital care, including mean drotrecogin alfa, activated drug cost of 7,312 US dollars, exceeded reimbursement by a mean of 18,227 US dollars.
