Sepsis is a major healthcare problem worldwide. Its mortality and morbidity is still high. Early diagnosis of sepsis and appropriate management in the initial hours improve outcomes. The Surviving Sepsis Campaign published new definitions for sepsis in 2016. In Sepsis-3 definitions, sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Organ dysfunction can be identified as an acute change in total SOFA score of at least two points consequent to the infection. However, this definition is endorsed by two international societies and there is much discussion regarding new definitions. Prospective validation of this definition on different levels is needed. The infectious source in sepsis depends on patients' underlying diseases and origin of the infection (community-acquired or healthcare-associated). In the literature, urinary tract and skin-soft tissue infection are the common sites in community-acquired sepsis, whereas respiratory system and intraabdominal infections are more common in nosocomial sepsis. Another challenge in sepsis management is the increasing incidence of sepsis due to multidrugresistant bacteria and limited treatment options. New antibiotics may be treatment options in the future. In this review, current definitions of sepsis, physiopathology of sepsis, foci of sepsis and causative microorganisms, microbiological diagnosis and rapid diagnosis methods, biomarkers used in the diagnosis of sepsis, antimicrobial treatment and resistance, new antibiotics and non-antibiotic therapy are discussed.

Objective: This paper intends to underline that malaria should be borne in mind in the differential diagnosis of patients with history of visiting endemic regions and of malaria prophylaxis for those intending to travel to these regions. Methods: 16 cases of P. falciparum malaria that were followed in the clinic between 2009 and 2015 were included in our study. Diagnosis was based on plasmodia seen under light microscope in thick and thin smears prepared from peripheral blood samples obtained from febrile patients and stained with Giemsa method. Results: Out of 16 patients, one was female and 15 were males. 14 of these patients, whose average age was 32 years, did not receive prophylaxis. Complaints of all patients were fever with chills, rigor, weakness, and anorexia; other accompanying complaints were headache, nausea, abdominal pain, diarrhea, cough and sore throat. Body temperatures over 38°C were detected in all patients. 11 patients were treated with artemether-lumefantrin and 5 patients treated with combination of quinine and doxycycline. Ertapenem was added in the treatment of a patient due to Serratia marcescens isolation in his blood culture obtained during his febrile period. Acute hepatitis A as a co-infection was detected in a patient and he was followed with symptomatic treatment. Somnolence, bleeding, bilateral pleural effusion and pulmonary infiltrates were observed in two patients diagnosed as severe malaria. Conclusions: Malaria chemoprophylaxis for the people intending to travel endemic regions is crucial. Klimik Dergisi 2016; 29(2): 86-9.
