The normal occurrence of two molecular forms of the eight complement component (C8) and their concentrations in a family with C8 deficiency.

A haemolytically inactive alpha-mobile complement C8 component was identified by crossed immunoelectrophoresis in a 27-year-old male with recurrent meningococcal infections and absence of complement mediated serum haemolytic activity. The patient's serum/plasma contained no demonstrable normal C8. C8 inhibitor activity was not demonstrable in his serum and the alternative activation pathway appeared to be intact. Serum from the proband's parents and both siblings had normal total haemolytic complement activity and they were without symptoms. However, both the normal and the haemolytically inactive C8 protein were demonstrable in their sera. Their normal C8 concentrations were less than one-half of the normal C8 mean value and distinctly below the lowest value found in ten healthy persons. The concentration of the inactive C8 component in the proband's serum was roughly 1 . 5 times higher than that of the other family members, whereas its concentration in sera of the family members was between 1 . 8 and 2 . 5 times the highest concentration found in ten healthy donors, all of whom also had an alpha-mobile C8 in measurable quantities.

Normal bactericidal capacity against Neisseria meningitidis in serum from a patient with a hemolytically inactive complement factor 8 (C8).

The bactericidal capacity of serum against Neisseria meningitidis from a 27-year-old male with two episodes of meningococcal meningitis and C8 deficiency was compared to that of normal human serum (NHS) without demonstrable antibodies against Neisseria. The in vitro bactericidal capacity of the patient serum was found to be equal to that of NHS. Incubation of both sera at 56 degrees C for 30 minutes abolished the bactericidal effect. Rocket-immunoelectrophoresis analysis of molecules immunochemically identifiable as C8 revealed no consumption of these molecules in any of the sera in the bactericidal assay. No hemolytic complement activity was found in the patient serum, whereas the donor serum had normal total hemolytic complement activity with significant consumption of C8.

Survival of diabetic hypertensive patients.

Seventy-nine of 673 patients attending a hypertensive outpatient clinic were classified as diabetics at the first examination. These patients were age- and sex-matched to two control groups: nondiabetic hypertensives and the background population. Nondiabetic hypertensive patients had a significantly poorer survival than expected during a 10-year observation period; the survival of diabetic hypertensives was even poorer, although not significantly. No sex difference was observed in the survival rates of hypertensive diabetics, neither was a difference seen between insulin-dependent and non-insulin-dependent patients. Acute myocardial infarction was the most frequent cause of death in both diabetic (40%) and nondiabetic (42%) hypertensive persons.
