Atypical Hemolytic Uremic Syndrome: A Case Report [PDF]

Cureus, 2019
Hemoytic uremic syndrome (HUS) is a rare type of thrombotic microangiopathies. Manifestations include thrombocytopenia, microangiopathic hemolytic anemia, and thrombi in small blood vessels. The prognosis is poor. Herein, we present a case of atypical HUS, which is very rare.

Meningococcal Serogroup Y Meningitis Reveals Inborn Factor B Deficiency

European Journal of Immunology, Volume 56, Issue 2, February 2026.
We report a novel case of complete complement Factor B deficiency revealed by invasive meningococcal disease. Using combined functional and genetic analyses, we demonstrate that loss of Factor B abolishes alternative pathway activity despite detectable protein levels. These findings provide a mechanistic framework relevant to complement diagnostics and

Atypical hemolytic uremic syndrome triggered by mRNA vaccination against SARS-CoV-2: Case report

Frontiers in Immunology, 2022
Atypical hemolytic uremic syndrome (aHUS), also called complement-mediated hemolytic uremic syndrome (CM-HUS), is a rare disease caused by dysregulation in the alternative complement activation pathway. It is a life-threatening condition causing ischemia

Atypical haemolytic-uraemic syndrome caused by factor H mutation: case report and new management strategies in children [PDF]

, 2012
Atypical haemolytic uraemic syndrome is causedby alternative complement pathway dysregulation. It has recently been recognised that most cases are due to genetic factors and a growing list of mutations has been described.

Thrombomodulin enhances complement regulation through strong affinity interactions with factor H and C3b-Factor H complex [PDF]

, 2016
Introduction Coagulation and complement systems are simultaneously activated at sites of tissue injury, leading to thrombin generation and opsonisation with C3b.

The Complement System in ANCA‐Associated Vasculitis: Mechanistic Insights, Therapeutic Horizons, and Unmet Clinical Needs

Immunity, Inflammation and Disease, Volume 14, Issue 2, February 2026.
Complement activation, particularly via the alternative pathway, drives inflammation and organ damage in ANCA‐associated vasculitis. This review highlights mechanistic insights, tissue and biomarker evidence, and clinical implications of targeting the C5a–C5aR1 axis.

Modulators of Diacylglycerol Kinase Activity: A Review of Advances and Challenges

Medicinal Research Reviews, Volume 46, Issue 1, Page 149-175, January 2026.
ABSTRACT Catalyzing the conversion of diacylglycerol (DAG) in phosphatidic acid (PA), diacylglycerol kinases (DGKs) play a pivotal role in all the physiological processes modulated by these two bioactive lipids, such as lipid metabolism and immune regulation.
