Staphylococcal bacteraemia/sepsis-characteristics of laboratory parameters.

INTRODUCTION: While determining a diagnosis and during a disease follow-up, laboratory, or non-specific inflammatory parameters in particular, platelets reference values, nitrogen matters, and liver enzymes play a significant role because their values may indicate multiple organ failures. GOALS: To analyse laboratory parameters in patients diagnosed with the staphylococcal bacteraemia/sepsis. PATIENTS AND METHODS: Analysed patients have been treated at the Clinic for Infectious Diseases through the period often years. RESULTS: Differences in average CRP values, leucocytes, neutrophils and platelets among the patients diagnosed with the sepsis and bacteraemia are not statistically relevant p > 0,05. Difference in the average sedimentation values of the erythrocytes between the patients diagnosed with the sepsis and the patients diagnosed with the bacteraemia are statistically relevant p = 0,035. Differences between the average INR values between the patients diagnosed with sepsis and the patients with bacteraemia are not statistically significant, but indicative p = 0,051. Differences in the average blood sugar values, urea, creatinine, bilirubin and ALT between the patients diagnosed with bacteraemia and sepsis are not statistically significant p > 0.05. CONCLUSION: The results have showed that even in the course ofa bacteraemia, there is a significant increase in the non-specific inflammatory parameters indicating the gravity ofbacteraemia as well, with a constant risk of developing sepsis and septic shock. The importance of running and following-up the laboratory parameters herewith is emphasised for the purpose of detecting sepsis in a timely manner and administering an adequate therapy.

Frequency of in-hospital acquired staphylococcus bacteremia/sepsis within ten-year period.

UNLABELLED: Analyzing data in the literature, it is noted that in-hospital acquired infections are an increasing problem even in more developed countries. This increasing trend is related to the progress of medical science and introduction of new invasive diagnostic-therapeutic methods, as well as increase of multiresistant types of bacteria, including staphylococci in big percentages. GOALS: To analyze frequency of in-hospital acquired staphylococcus bacteremia/sepsis. PATIENTS AND METHODS: Anamneses of patients who were diagnosed with staphylococcus bacteremia/sepsis were analyzed within a ten-year period. RESULTS: Within the analyzed period from 2001 to 2011, there were 87 patients with diagnosis of staphylococcus bacteremia/sepsis, out of which (20) 77% were diagnosed with sepsis, and (67) 23% with bacteremia. In-hospital outcome was present with 32 (36.8%) patients, while 55 (63.2%) were out of hospital. The chi-square test for independence showed that the diagnosis of bacteremia/sepsis and the place of the infection origin (in hospital/ out of hospital) were independent chi2 = 1.951 df= 1 p=0.162. The cause isolated from hemoculture depends on the place of the infection origin (out of hospital/in hospital); larger percentage of methicillin-resistant types was presented in in-hospital acquired infections chi2 11.352 df=1 p=0.001. And the chi-square test for independence showed both dependence of the preceding antibiotic treatment and the place of the infection origin in both categories of patients. Sepsis: chi2 = 22.92 df=1 p<0.0005; Bacteremia: chi2 = 9.89 df=1 p= 0.005. CONCLUSION: The results showed larger percentage of methicillin-resistant types in in-hospital acquired infections, as well as significantly larger percentage of hospital infections with the preceding antibiotic therapy, which puts in focus possible rationalization of including antibiotic therapy.
