OBJECTIVE: The Pediatric Sepsis Biomarker Risk Model (PERSEVERE), a pediatric sepsis risk model, uses biomarkers to estimate baseline mortality risk for pediatric septic shock. It is unknown how PERSEVERE performs within distinct septic shock phenotypes. We tested PERSEVERE in children with septic shock and thrombocytopenia-associated multiple organ failure (TAMOF), and in those without new onset thrombocytopenia but with multiple organ failure (MOF). DESIGN: PERSEVERE-based mortality risk was generated for each study subject (n = 660)...

TAMOF is a devastating microangiopathy that can occur in association with the new onset of T1DM, and should be considered with the onset of thrombocytopenia, renal failure, and raised LDH. Treatment with fresh frozen plasma should be considered as a first-line option in such cases prior to plasma exchange.

Thrombocytopenia-associated multi-organ failure (TAMOF) is an increasingly reported entity in the pediatric intensive care unit. The clinical presentation is similar to thrombotic thrombocytopenic purpura, but with no evidence of hemolysis and no schistocytes on peripheral smear. We report a case of TAMOF induced by diabetic ketoacidosis and treated with therapeutic plasma exchange (TPE). Early diagnosis and initiation of TPE significantly decrease the morbidity associated with TAMOF.

Thrombocytopenia-associated multiple organ failure (TAMOF) is a clinical phenotype that encompasses a spectrum of syndromes associated with disseminated microvascular thromboses, such as the thrombotic microangiopathies thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS) and disseminated intravascular coagulation (DIC). Autopsies findings in TTP, HUS, or DIC reveal specific findings that can differentiate these 3 entities. Von Willebrand factor and ADAMTS-13 play a central role in TTP. Shiga toxins and the complement pathway are vital in the development of HUS...

Thrombotic microangiopathic syndrome secondary to diabetic ketoacidosis is an under reported entity in children. We describe 2 girls who developed thrombotic thrombocytopenic purpura (TTP) and thrombocytopenia associated multi organ failure (TAMOF) in new onset diabetes. Both patients presented with classical findings of DKA and were intubated due to low GCS, admitted in PICU and managed according to DKA guidelines. Later on, both patients developed thrombocytopenia, acute kidney injury, and low hemoglobin along with evidence of microangiopathy on peripheral smear...

Thrombocytopenia-associated multiple organ failure (TAMOF) is a thrombotic microangiopathic syndrome that includes thrombotic thrombocytopenic purpura, secondary thrombotic microangiopathy, and disseminated intravascular coagulation. We report a case of postpartum female who presented with TAMOF or severe Haemolysis, elevated liver enzymes, low platelet count (HELLP) which was managed with plasma exchange. This case report is to make clinicians aware that TAMOF, severe HELLP, and other differential diagnosis in a postpartum case have a thin differentiating line and plasma exchange can be considered as one of the management options...

INTRODUCTION: Thrombotic microangiopathy (TMA) is characterized by microvascular thrombosis, thrombocytopenia, and microangiopathic hemolytic anemia. Previous studies have shown that cyclosporine (CsA) is associated with TMA but the number of reported cases is very limited. We describe a 13-year-old girl with CsA-associated TMA and thrombocytopenia-associated multiple organ failure (TAMOF). CASE REPORT: The patient was diagnosed with polyglandular deficiency syndrome and had a history of celiac disease, autoimmune thyroiditis, and diabetes mellitus type I...

Thrombocytopenia-associated multiple organ failure (TAMOF) has a high mortality rate when not treated, and early detection of TAMOF is very important diagnostically and therapeutically. We describe herein our experience of early detection of TAMOF, using an automated hematology analyzer. From 498,390 inpatients, we selected 12 patients suspected of having peripheral schistocytosis, based on the results of red blood cell (RBC) parameters and a volume/hemoglobin concentration (V/HC) cytogram. We promptly evaluated whether the individual patients had clinical manifestations and laboratory findings were consistent with TAMOF...

A high proportion of the patients with Salmonella enterica serotype Typhi infection develop severe sepsis. The mortality rate is high despite aggressive antimicrobial therapy in these patients. The case of a 10-year-old boy who developed thrombocytopenia-associated multiple organ failure (TAMOF) secondary to S. typhi infection is reported. The patient did not respond to antimicrobial treatment, including ciprofloxacin, in addition to conventional supportive measures, so plasma exchange was performed. The thrombocytopenia and organ failure had resolved after 3 days of plasma exchange therapy...

BACKGROUND: Thrombocytopenia-associated multiple organ failure (TAMOF) is a poorly understood syndrome in critically ill children. A disintegrin and metalloprotease with thrombospondin motifs (ADAMTS-13), formerly known as von Willebrand factor (VWF) cleaving protease, is decreased in adults with VWF-mediated thrombotic microangiopathy, and intensive plasma exchange (PEx) both replenishes ADAMTS-13 and improves outcome in these patients. OBJECTIVES: To determine whether: 1) critically ill children with TAMOF syndrome have decreased ADAMTS-13 activity, 2) ADAMTS-13 activity correlates with platelet counts and VWF antigen, 3) the autopsies from patients who died with reduced ADAMTS-13 activity have VWF-rich microthrombi, and 4) intensive PEx will restore ADAMTS-13 activity and facilitate organ failure resolution...

New onset thrombocytopenia and multiple organ failure (TAMOF) presages poor outcome in critical illness. Patients who resolve thrombocytopenia by day 14 are more likely to survive than those who do not. Patients with TAMOF have a spectrum of microangiopathic disorders that includes thrombotic thrombocytopenic purpura (TTP), disseminated intravascular coagulation (DIC) and secondary thrombotic microanigiopathy (TMA). Activated protein C is effective in resolving fibrin-mediated thrombosis (DIC); however, daily plasma exchange is the therapy of choice for removing ADAMTS 13 inhibitors and replenishing ADAMTS 13 activity which in turn resolves platelet: von Willebrand Factor mediated thrombosis (TTP/secondary TMA)...
