[Severe infections : causes and management of sepsis]

[First-line anti-infective treatment in sepsis]

BACKGROUND

The Surviving Sepsis Campaign strongly recommends that intravenous antibiotic therapy should be started as early as possible, ideally within the first hour of recognition of severe sepsis or septic shock. There is ample evidence that failure to initiate early antimicrobial treatment correlates with increased morbidity and mortality.

OBJECTIVES

The purpose of this work was to review the recent literature regarding optimal initial antimicrobial treatment in patients with severe sepsis and sepsis shock.

MATERIALS AND METHODS

A literature review was performed.

RESULTS

The most frequently quoted papers claiming the overriding prognostic importance of early administered antibiotics are retrospective data analyses. However, an equivalent number of studies report that a group of septic patients do not benefit from early administration of antibiotics, but can also be harmed. In these patients, watchful waiting with administration of a targeted antibiotic can be used, thus, avoiding the possible collateral damage from excessive treatment with antibiotics. Treatment with monotherapy is adequate in most cases.

CONCLUSION

The administration of antibiotics based on the local epidemiology should be initiated quickly in critically ill patients with severe sepsis and septic shock. In patients who are not in septic shock, treatment can be withheld, while awaiting further studies or clinical assessment to confirm the suspicion of infection.

[Malaria]

Malaria is the most important infectious disease imported by travelers and migrants from tropical and subtropical areas. It is imported quite frequently. It is a life-threatening disease. Symptoms are nonspecific and cannot easily be distinguished from a wide range of other febrile conditions. Therefore, travel history must be taken in all patients with fever of unknown origin and malaria diagnostics must be performed immediately on suspicion of malaria. Uncomplicated falciparum malaria should be treated in the hospital with either atovaquone-proguanil or with an artemisinin-based combination preparation. If there is evidence of severe malaria, the patient must be moved to an intensive care unit. The antiparasitic agent of choice is then artesunate.
