Sepsis represents a severe pathology that requires both rapid and precise positive and differential diagnosis to identify patients who need immediate antimicrobial therapy. Monitoring septic patients’ outcome leads to prolonged hospitalisation and antibacterial therapy, often accompanied by substantial side effects, complications and a high mortality risk.Septic patients present with complex pathophysiological and immunological disorders and with a predominance of pro-inflammatory or anti-inflammatory mediators which are heterogeneous with respect to the infectious focus, the aetiology of sepsis or patients’ immune status or comorbidities. Previous studies performed have analysed inflammatory biomarkers, but a test or combinations of tests that can quickly and precisely establish a diagnosis or prognosis of septic patients has yet to be discovered. Recent research has focused on re-analysing older accessible parameters found in the complete blood count to determine the sensitivity, specificity, positive and negative predictive values for the diagnosis and prognosis of sepsis.The neutrophil/lymphocyte count ratio (NLCR), mean platelet volume (MPV) and red blood cells distribution width (RDW) are haemogram indicators which have been evaluated and which are of proven use in septic patients’ management.

Aims:To evaluate the kinetics of inflammatory biomarkers in septic patients in order to identify the most reliable predictor of unfavorable outcome. Methods: A prospective analysis of septic patients was performed. Median levels of neutrophil/lymphocyte count ratio, fibrinogen, C-reactive protein and procalcitonin were dynamically assessed and comparatively analyzed. Results: Seventy-seven patients were included. Descendent kinetic patterns were registered for all biomarkers, except C-reactive protein. At 24 hours, neutrophil/lymphocyte count ratio significantly decreased in 42.85% of cases, procalcitonin in 37.33%, C-reactive protein in 16.12% and fibrinogen in 1.58% of cases. At 72 hours, procalcitonin decreased to one-half in 70% of cases and neutrophil/lymphocyte count ratio in 67.53% of cases. Conclusions: Neutrophil/lymphocyte count ratio and procalcitonin significantly decreased in the first 72 hours, while C-reactive protein increased in the first 24 hours. The proportions of patients with major decrease of baseline values were higher for neutrophil/lymphocyte count ratio and procalcitonin.

IntroductionStreptococcal infection can be responsible for multiple complications, such as toxic, septic or allergic disorders. Toxin-mediated complications (TMC) can appear during the acute phase of disease and can involve any organ, causing carditis, arthritis, nephritis, hepatitis etc.Case presentationThe case of a young woman without a history of recurrent streptococcal tonsillitis, admitted to “Matei Balş” National Institute for Infectious Diseases, Bucharest, Romania, presenting with fever, sore throat and exudative tonsillitis, is detailed. The initial test for Streptococcus pyogenes was negative. The patient had leukopenia with severe neutropenia, high values of inflammatory biomarkers and electrocardiographic (ECG) changes with inverted T waves in leads V1-4 and flattened T waves in V5-6. There were no other cardiac signs or symptoms. The patient received cefuroxime for two days. On admission, the patient was prescribed Penicillin G and dexamethasone which resulted in a rapid recovery. The leucocytes count returned to normal as did the ECG abnormalities. At the time of discharge, the antistreptolysin O titre was high.ConclusionsThe case highlights the toxin-mediated complications (TMC) of streptococcal infection which occur from the outset of the disease.
