Evans syndrome as a presentation in systemic lupus erythematous, coexisting with Hashimoto's thyroiditis and pernicious anemia: a case report.
J Med Case Rep
December 2024
Faculty of Medicine, Al-Quds University, Jerusalem, Palestine.
Background: Evans syndrome is a rare disorder characterized by the simultaneous or sequential combination of autoimmune hemolytic anemia and immunological thrombocytopenia, together with a positive direct antiglobulin test. This syndrome, which can be primary or secondary, is a rare initial manifestation of autoimmune diseases, notably systemic lupus erythematosus, with 1.7-2.

Background: Thrombocytopenia (TP) is a hematological manifestation of systemic lupus erythematosus (SLE) and is associated with unfavorable prognostic outcomes. This study aimed to develop a risk prediction model for new-onset TP in SLE patients.
Methods: Based on the multicenter prospective Chinese SLE Treatment and Research Group (CSTAR) registry, newly diagnosed SLE patients without TP at registration were enrolled.
Reduction in Renal Heme Oxygenase-1 Is Associated with an Aggravation of Kidney Injury in Shiga Toxin-Induced Murine Hemolytic-Uremic Syndrome.

Department of Anesthesiology and Intensive Care Medicine, Jena University Hospital, Am Klinikum 1, 07747 Jena, Germany.
Hemolytic-uremic syndrome (HUS) is a systemic complication of an infection with Shiga toxin (Stx)-producing enterohemorrhagic , primarily leading to acute kidney injury (AKI) and microangiopathic hemolytic anemia. Although free heme has been found to aggravate renal damage in hemolytic diseases, the relevance of the heme-degrading enzyme heme oxygenase-1 (HO-1, encoded by ) in HUS has not yet been investigated. We hypothesized that HO-1 also important in acute phase responses in damage and inflammation, contributes to renal pathogenesis in HUS.

Toxins (Basel)
December 2024
Molecular Toxinology Lab, Research and Development Department, Ezequiel Dias Foundation-FUNED, Belo Horizonte 30510-010, MG, Brazil.
Spiders of the genus represent a public health problem in Brazil due to the severity of the cutaneous and systemic effects that may result from their bite. In the systemic form of loxoscelism, hemolytic anemia, thrombocytopenia, and disseminated intravascular coagulation can occur. Despite the seriousness of accidents, the venom of some species has not yet been properly characterized considering these hemotoxic effects, such as that of , , and .

Shiga toxin-producing (STEC) refers to a group of bacteria that can cause infections, which are common worldwide and pose a serious public health problem, as they can lead to conditions such as hemorrhagic colitis and hemolytic uremic syndrome (HUS). HUS is a disease characterized by microangiopathic hemolytic anemia, thrombocytopenia, and renal failure. Determination of serogroups and toxin profiles of STEC is important for estimating their disease-causing potential and predicting epidemiological changes.
