Experimental data suggest that the host's inflammatory response is involved in the pathophysiology of verotoxin-producing Escherichia coli (VTEC)-associated hemolytic uremic syndrome (HUS). We compared the circulating levels of pro- [interleukin (IL)-6, IL-8] and anti-inflammatory [IL-10 and IL-1 receptor antagonist (Ra)] mediators on enrollment among children with HUS due to E. coli O157:H7, according to the severity of renal dysfunction. The latter was evaluated by the occurrence of oligoanuria, the requirement for dialysis, and a glomerular filtration rate (GFR)

The role of the complement system in Shiga toxin-associated hemolytic uremic syndrome.

Background: This research explores complement activation products involvement and risk and protective polymorphisms in the complement alternative pathway genes in Shiga toxin-associated hemolytic uremic syndrome (STEC-HUS) pathogenesis.
Methods: We analyzed the levels of complement activation products, C3a, C5a and soluble C5b-9 (sC5b-9) and plasma concentrations of Factor H (FH) and FH-related protein 1 (FHR-1) in 44 patients with STEC-HUS, 12 children with STEC-positive diarrhea (STEC-D), and 72 healthy controls (HC). STEC-HUS cases were classified as "severe" or "non-severe".
Vascular injury in glomerulopathies: the role of the endothelium.

Renal Pathophysiology Laboratory, Hospital das Clínicas, University of São Paulo School of Medicine, São Paulo, Brazil.
In glomerulopathies, endothelial dysfunction and the presence of histological vascular lesions such as thrombotic microangiopathy, arteriolar hyalinosis, and arteriosclerosis are related to a severe clinical course and worse renal prognosis. The endothelial cell, which naturally has anti-inflammatory and anti-thrombotic regulatory mechanisms, is particularly susceptible to damage caused by various etiologies and can become dysfunctional due to direct/indirect injury or a deficiency of protective factors. In addition, endothelial regulation and protection involve participation of the complement system, factors related to angiogenesis, the renin-angiotensin system (RAS), endothelin, the glycocalyx, the coagulation cascade, interaction between these pathways, interactions between glomerular structures (the endothelium, mesangium, podocyte, and basement membrane) and interstitial structures (tubules, arterioles and small vessels).

Following its discovery as an adaptive immune system in prokaryotes, the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated proteins (Cas) system has been developed into a multifaceted genome editing tool. This review compiles findings aimed at implementation of this technology for selective elimination or attenuation of enterohemorrhagic (EHEC). EHEC are important zoonotic foodborne pathogens that cause hemorrhagic colitis and can progress to the life-threatening hemolytic uremic syndrome (HUS).

The SARS-CoV-2 virus can cause thrombotic microangiopathy (TMA) by alternate pathway activation. We present a case of a young female patient who presented with fever and dialysis-dependent acute kidney injury. On evaluation, she was diagnosed with COVID-19-induced complement-mediated thrombotic microangiopathy (CM-TMA).
