One patient generated no anti-C6 or anti-pepC10 in MENSA or serum throughout the period of observation; one patient produced substantial levels of serum and MENSA antibodies for at least 96 days, possibly indicating non-resolution of his infection; others (n = 5) displayed rises in both serum and MENSA antibody levels followed by declines to or near baseline; and one patient produced an unexpectedly large anti-C6 response in MENSA samples while producing modest levels of antibody in serum. Here, C6 is linked to infection.
