We report the unusual case of a 5-year-old male hospitalized for management of diabetic ketoacidosis (DKA) and new-onset type 1 diabetes mellitus (T1DM) who developed acute renal injury secondary to hemolytic uremic syndrome (HUS). He was diagnosed with Shiga toxin-producing entero-hemorrhagic Escherichia coli (EHEC) 0157:H7-positive HUS 48 hours after being diagnosed with new-onset T1DM/DKA. His hospital course was complicated by Clostridium septicum sepsis with colonic perforation. This patient's diagnosis of new-onset T1DM just prior to HUS is novel...

BACKGROUND: Stroke is the leading cause of mortality and disability worldwide. Several definite risk factors have been identified for stroke, although infectious factors might also contribute to stroke episodes through increased susceptibility or direct induction. CASE PRESENTATION: A 46-year-old Chinese male initially presented with fever, headache, and impaired memory and developed disturbance of consciousness after admission. A clinical diagnosis of Staphylococcus aureus sepsis, massive cerebral infarction and haemorrhagic transformation (left internal carotid arterial system, inflammatory thrombus) were made based on brain radiography, blood culture and postoperative pathological examinations...

Jueseong Lee, Yong Hyeon Bang, Eun Hee Lee, Byung Min Choi, Young Sook Hong
PURPOSE: Although procalcitonin (PCT) level is useful for the diagnosis of neonatal sepsis, PCT reliability is inconsistent because of the varied conditions encountered in neonatal intensive care units. This study aimed to investigate PCT levels and factors influencing increased PCT levelin newborns without bacterial infection during the first week of life. METHODS: In newborns hospitalized between March 2013 and October 2015, PCT levels were measured on the first, third, and seventh days after birth...

This paper describes the evolution of our understanding of the biological role played by synthetic and natural antimicrobial cationic peptides and by the highly basic nuclear histones as modulators of infection, postinfectious sequelae, trauma, and coagulation phenomena. The authors discuss the effects of the synthetic polymers of basic poly α amino acids, poly l-lysine, and poly l-arginine on blood coagulation, fibrinolysis, bacterial killing, and blood vessels; the properties of natural and synthetic antimicrobial cationic peptides as potential replacements or adjuncts to antibiotics; polycations as opsonizing agents promoting endocytosis/phagocytosis; polycations and muramidases as activators of autolytic wall enzymes in bacteria, causing bacteriolysis and tissue damage; and polycations and nuclear histones as potential virulence factors and as markers of sepsis, septic shock, disseminated intravasclar coagulopathy, acute lung injury, pancreatitis, trauma, and other additional clinical disorders...

Objective The objective of this study was to assess the result of intravenous pentoxifylline as an adjunct to antibiotic therapy on mortality and morbidity in very low birth weight (VLBW) preterm neonates with nosocomial sepsis. Methods For the 18 VLBW preterm neonates, as an adjunct therapy to antibiotics regimens, pentoxifylline (5 mg/kg/h for 6 hours) was administered to premature infants with sepsis on 3 successive days. Clinical and laboratory parameters were recorded before and after treatment. Results Following pentoxifylline therapy, the immature-to-total neutrophil ratio and C-reactive protein (CRP) levels were significantly decreased, while the blood pH and base excess were significantly increased (p < 0...

Multidrug-resistant (MDR) gram-negative bacteria have increased the prevalence of fatal sepsis in modern times. Colistin is a cationic antimicrobial peptide (CAMP) antibiotic that permeabilizes the bacterial outer membrane (OM) and has been used to treat these infections. The OM outer leaflet is comprised of endotoxin containing lipid A, which can be modified to increase resistance to CAMPs and prevent clearance by the innate immune response. One type of lipid A modification involves the addition of phosphoethanolamine to the 1 and 4' headgroup positions by phosphoethanolamine transferases...

BACKGROUND: Tropical diabetic hand syndrome describes a complex hand sepsis affecting patients with diabetes across the tropics and often results from a trivial hand trauma. The clinical presentation of this syndrome is variable and ranges from localised swelling and cellulitis, with or without ulceration of the hand to progressive fulminant hand sepsis, and gangrene affecting the entire limb which may be fatal. Tropical diabetic hand syndrome could lead to permanent disability and death as a result of delay in presentation, late diagnosis and late medical and surgical intervention...

Adult onset Still's disease is uncommon in middle-aged and elderly individuals and can rarely present with shock; shock is usually associated with disseminated intravascular coagulation, multiorgan dysfunction syndrome or acute respiratory distress syndrome. We report a post-menopausal woman with arthritis, fever, pneumonitis and hypotension which was managed as septic shock. Steroids were inadvertently missed during the second day of hospitalization in the intensive care unit. Persistence of hypotension on inotropes, with normal renal, hepatic and neurological function and recurrence of fever when steroids were skipped, led to suspicion of an inflammatory disorder...

Metformin-associated lactic acidosis (MALA) is a rare but life-threatening complication. We report a case of MALA in a man aged 71 years who was treated with continuous renal replacement therapy (CRRT). The patient was brought to the hospital for prolonged and gradual worsening gastrointestinal symptoms. Although he received intravenous treatment, he developed catecholamine-resistant shock, and blood gas analysis revealed lactic acidosis. Bicarbonate and antibiotics for possible sepsis were initiated, but with no clear benefit...

Melioidosis is a neglected tropical disease that is caused by the bacterium Burkholderia pseudomallei, and is underreported in many endemic countries. A long and costly administration of antibiotics is required to clear infections, and there is an unmet need for biomarkers to guide antibiotic treatment and increase the number of patients that complete therapy. We identified calprotectin as a lead biomarker of Burkholderia pseudomallei infections, and examined correlations between this serum protein and antibiotic treatment outcomes of melioidosis patients...

Staphylococcus aureus infection is a persistent threat in resource-restricted settings in southeast Asia but informative data about this disease remain limited. We analyzed characteristics, management, and predictors of outcome in severely septic patients with community-onset S. aureus infection in northeast Thailand. We performed a prospective, multicenter observational cohort study of community-onset S. aureus sepsis in four referral hospitals recruiting patients at least 14 years of age admitted between March 2010 and December 2013...

A major obstacle to therapy in intensive care units is sepsis caused by severe infection. In recent years gram-positive (G(+)) bacteria, most commonly staphylococci, are thought to be the main pathogens. Micheliolide (MCL) was demonstrated to provide a therapeutic role in rheumatoid arthritis, inflammatory intestinal disease, colitis-associated cancer, and lipopolysaccharide (LPS, the main component of G(-) bacterial cell wall) induced septic shock. We proved here that MCL played an anti-inflammatory role in Staphylococcus aureus (S...

Diverticulitis primarily affects the sigmoid colon and is often complicated by intra-abdominal abscesses and fistulas. Rarely, however, mesenteric venous thrombosis has been known to occur. Optimal management is still unclear. We report the first case of polymicrobial sepsis resulting from diverticular pylephlebitis, managed successfully with bowel rest, antibiotics, and anticoagulation.
