Microangiopathic haemolytic anaemia and systemic vasculitis
British Journal of Rheumatology
|April 1, 1996
Summary
Systemic vasculitis rarely presents with microangiopathic hemolytic anemia (MAHA). This report details two unique cases, suggesting a potential link to von Willebrand factor abnormalities.
Area of Science:
- Internal Medicine
- Rheumatology
- Hematology
Background:
- Systemic vasculitis encompasses a group of disorders characterized by inflammation of blood vessels.
- Microangiopathic hemolytic anemia (MAHA) is a condition involving red blood cell destruction within small blood vessels.
Observation:
- Two patients with systemic vasculitis presented with atypical symptoms: parotitis in one and Guillain-Barré syndrome in the other.
- Both patients developed microangiopathic hemolytic anemia (MAHA), an association not previously documented in the literature.
Findings:
- Diagnostic workup excluded other potential causes of MAHA in both patients.
- The study speculates a potential association between systemic vasculitis complicated by MAHA and macromolecular von Willebrand factor.
Implications:
- This report highlights a rare complication of systemic vasculitis, expanding the spectrum of its clinical manifestations.
- Further research is warranted to elucidate the pathogenic mechanisms linking vasculitis, MAHA, and von Willebrand factor.
- Recognizing this association may aid in earlier diagnosis and management of patients with complex systemic vasculitis.

01:24Disorders of Hemostasis
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

01:01Hypersensitivity Reactions: Cytolytic Reactions
Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...
01:25Acute Inflammation III: Local and Systemic Effects
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
