REVIEW
Tamer Akel, Neville Mobarakai
BACKGROUND: Babesiosis, a zoonotic parasitic infection transmitted by the Ixodes tick, has become an emerging health problem in humans that is attracting attention worldwide. Most cases of human babesiosis are reported in the United States and Europe. The disease is caused by the protozoa of the genus Babesia, which invade human erythrocytes and lyse them causing a febrile hemolytic anemia. The infection is usually asymptomatic or self-limited in the immunocompetent host, or follows a persistent, relapsing, and/or life threatening course with multi-organ failure, mainly in the splenectomized or immunosuppressed patients...

BACKGROUND: Therapeutic plasma exchange (TPE) is a generally accepted and frequently performed procedure for numerous therapeutic indications in adults. Slowly, TPE is also becoming more and more popular in the treatment of pediatric patients. Although, we know that TPE is safe in pediatric patients, the outcome of children treated with TPE is rarely reported. Furthermore, there are only general recommendations regarding the plasma replacement fluid for children and these are adopted from adults...

Bas C T van Bussel, Marcel C G van de Poll, Casper G Schalkwijk, Dennis C J J Bergmans
Molecular pathological pathways leading to multi-organ failure in critical illness are progressively being unravelled. However, attempts to modulate these pathways have not yet improved the clinical outcome. Therefore, new targetable mechanisms should be investigated. We hypothesize that increased dicarbonyl stress is such a mechanism. Dicarbonyl stress is the accumulation of dicarbonyl metabolites (i.e., methylglyoxal, glyoxal, and 3-deoxyglucosone) that damages intracellular proteins, modifies extracellular matrix proteins, and alters plasma proteins...

REVIEW
Thomas Efferth, Manfred Volm
The detoxification of toxic substances is of general relevance in all biological systems. The plethora of exogenous xenobiotic compounds and endogenous toxic metabolic products explains the evolutionary pressure of all organisms to develop molecular mechanisms to detoxify and excrete harmful substances from the body. P-glycoprotein and other members of the ATP-binding cassette (ABC) transporter family extrude innumerous chemical compounds out of cells. Their specific expression in diverse biological contexts cause different phenotypes: (1) multidrug resistance (MDR) and thus failure of cancer chemotherapy, (2) avoidance of accumulation of carcinogens and prevention of carcinogenesis in healthy tissues, (3) absorption, distribution, metabolization and excretion (ADME) of pharmacological drugs in human patients, (4) protection from environmental toxins in aquatic organisms (multi-xenobiotic resistance, MXR)...

Acute Pancreatitis (AP) is a potentially fatal syndrome, associated with a hyper-catabolic state as well as early and late complications that may lead to multi-organ failure and death. Clinical researches produced in recent years suggest that acute pancreatitis may benefit from early oral or enteral nutrition. Nevertheless, many clinicians still believe erroneously that fasting - particularly in the early phase - may reduce AP complications and mortality. The goal of our review is to demonstrate that such false belief may harm the patients and that the whole management paradigm must change, adopting a more rational, evidence-based approach...

A 64-year-old Japanese man with multiple myeloma was admitted to our institute due to fever and hypotension. He had received multiple courses of chemotherapy just before his febrile episode. Blood culturing detected Morganella morganii. At the time of the diagnosis, his laboratory findings revealed massive rhabdomyolysis with a significantly increased creatinine kinase level (CK; 3,582 U/L); 98.8% of which corresponded to the CK-MB isotype. We diagnosed the patient with sepsis caused by M. morganii, complicated with severe rhabdomyolysis...

Acute kidney injury (AKI) is an important complication in burn patients. Recently, it has been recommended that hydroxyethyl starch (HES) be avoided in burn patients because it increases the incidence of AKI. Our purpose was to study incidence of AKI in critically ill burn patients resuscitated with Ringer's solution and supplements of HES. We conducted an observational study of 165 patients admitted to the critical care burn unit (with 30 ± 15% TBSA burned). The main outcome measures were incidence of AKI, contributions of colloids and crystalloids, various severity scores, comorbidities, complications and mortality...

BACKGROUND: Sepsis is a systemic inflammatory response usually correlated with multi-organ failure. Myocardial dysfunction is one of the adverse outcomes in septic patients and results in high mortality rates. The aim of this study was to investigate the impact of irbesartan in attenuation of cardiac depression during polymicrobial sepsis via decreased activation of the phospho-p38MAPK/nuclear factor (NF)-κB signaling pathway. MATERIALS AND METHODS: A model of polymicrobial sepsis induced via cecal ligation and puncture (CLP) with 8- to 12-week-old albino mice was used...

BACKGROUND: Leptospirosis is an important zoonotic disease worldwide. Humans usually present a mild non-specific febrile illness, but a proportion of them develop more severe outcomes, such as multi-organ failure, lung hemorrhage and death. Such complications are thought to depend on several factors, including the host immunity. Protective immunity is associated with humoral immune response, but little is known about the immune response mounted during naturally-acquired Leptospira infection...

Although studies in rat cultured pulmonary artery endothelial cells, perfused lungs, and intact mice support the concept that oxidative mitochondrial (mt) DNA damage triggers acute lung injury (ALI), it has not yet been determined whether enhanced mtDNA repair forestalls development of ALI and its progression to multiple organ system failure (MOSF). Accordingly, here we examined the effect of a fusion protein construct targeting the DNA glycosylase, Ogg1, to mitochondria in a rat model intra-tracheal P. aeruginosa (strain 103; PA103)-induced ALI and MOSF...

BACKGROUND: A proportion of patients with acute pancreatitis (AP) develop necrosis. Around a third will become infected, and this is associated with a significant requirement for intervention and support. We evaluated the burden of necrotizing pancreatitis (NP) in an Australian tertiary hospital with regards to morbidity, mortality and resource consumption. METHODS: This is a retrospective case series of patients with AP admitted for at least 5 days to identify those with NP between 2009 and 2014...

Methotrexate is a frequently prescribed drug and is considered to be safe at a low dosage. However, serious complications may occur during treatment. In this article we describe a 78-year-old male who used low-dose methotrexate for psoriatic arthritis. He died of multi-organ failure caused by sepsis and methotrexate intoxication as a result of deteriorating renal function. The second patient was a 56-year-old male who used low-dose methotrexate for rheumatoid arthritis. This patient developed pancytopenia and methotrexate pneumonitis during treatment with methotrexate...

Sinusoidal obstructive syndrome (SOS) is a potentially fatal form of hepatic injury following hematopoietic stem cell transplant (HSCT). Patients can develop liver dysfunction, portal hypertension, ascites, coagulopathies, and multi-system organ failure. The mortality rate of severe SOS has been reported as high as 98% by Day 100 post-transplant. Defibrotide, which is now approved for the treatment of SOS, has significantly decreased mortality. Defibrotide is a polynucleotide with pro-fibrinolytic, anti-ischemic, and anti-inflammatory activity...

Heart failure (HF) is a debilitating disease in which abnormal function of the heart leads to imbalance of blood demand to tissues and organs. The pathogenesis of HF is very complex and various factors can contribute including myocardial infarction, ischemia, hypertension and genetic cardiomyopathies. HF is the leading cause of death and its prevalence is expected to increase in parallel with the population age. Different kind of therapeutic approaches including lifestyle modification, medication and pacemakers are used for HF patients in NYHA I-III functional class...

When a patient receiving anti-cancer treatment presents acutely unwell, an understanding of associated side effects of their therapy is critical. This review will discuss the approach to patients receiving anti-cancer treatment with immunotherapy presenting with autoimmune toxicities in the emergency setting. These toxicities are commonly referred to as immune-related adverse events (irAE). IrAE might consist of, but are not limited to, dermatologic, gastrointestinal (diarrhoea, colitis), hepatic, endocrine (thyroid dysfunction, hypophysitis, adrenal crisis), renal, ocular and pulmonary toxicity...
