Vision problems, mental retardation, and potential for myocardial infarction and/or stroke. See: Notes on Amino Acid Metabolism Disorders
What are the different types of rapidly progressive (crescentic) glomerulonephritis?
• RPGN Type I: characterized by anti-GBM antibodies. Linear deposits of IgG and C3 found on immunofluorescence. Associated with Goodpasture syndrome.
• RPGN Type II: immune-complex mediated. "Lumpy bumpy" granular pattern.
• RPGN Type III: "Pauci immune." ANCA in serum.
What happens in patients with deficiencies that form membrane attack complex (MAC, C5b-C9)?
Infection by Neisseria species.
What may be a cause of pure T-cell dysfunction?
DiGeorge syndrome.
What may be a cause of ineffective intracellular killing?
Chronic granulomatous disease.
Which bacterial toxins inhibit protein synthesis?
E. coli (EHEC) and S, dysenteriae block 60s ribosomal subunit, thereby, blocking protein synthesis.
What is the pathogenicity of B. anthracis?
Antiphagocytic D-glutamate capsule (protein capsule).
