1/5. Complete and partial deficiencies of complement factor d in a Dutch family.

    A young man suffering from recurrent neisseria infections was shown to lack detectable serum complement factor d hemolytic activity. Addition to the patient's serum of purified factor D to a final concentration of 1 microgram/ml resulted in full restoration of the activity of the alternative pathway. Using an enzyme-linked immunosorbent assay, it was shown that the patient's serum did not contain measurable amounts of factor D antigen either. The sister, the father, as well as the parents of the mother had factor D levels within the normal range, and the factor D level of the mother was decreased. The capacity of the patient's serum, at concentrations up to 5%, to promote phagocytosis of escherichia coli by normal human granulocytes was low when compared to normal serum. Substitution of the patient's serum with purified factor D resulted in a full restoration of opsonic activity. This study describes the first complete deficiency of factor D, and demonstrates its possible relation to recurrent neisseria infections.

2/5. Treatment of venereal disease in the penicillin-allergic patient: administration of penicillin following testing with major and minor determinants.

    We describe the administration of penicillin for venereal disease in three penicillin-allergic patients for whom alternative antibiotics were not considered suitable. Each patient was skin test negative to the major penicillin determinant benzylpenicilloyl-polylysine and a minor determinant mixture of potassium penicillin, benzylpenicilloate and benzylpenicilloyl-n-propylamine provided by the National Institute of Allergy and Infectious Diseases. Therapeutic doses of penicillin were administered without anaphylaxis, but one patient developed serum sickness on day five following benzylpenicillin. The skin testing results were determined within 30 minutes such that penicillin or its derivatives could be administered safely and rapidly to seriously ill patients, i.e. disseminated gonococcemia. When treating neurosyphilis or disseminated gonococcal infection for which non-penicillin therapy is unacceptable, use of the current skin test reagents provides a level of safety in avoiding anaphylaxis not previously attainable.

3/5. Deficiency of the fifth component of complement in human subjects. Clinical, genetic and immunologic studies in a large kindred.

    The discovery of a large kindred with a heritable deficiency of the fifth component of complement (C5) has permitted the accumulation of new clinical, genetic and immunologic data concerning the role of C5 in human subjects. The proband, who has had nine episodes of disseminated gonococcal infection, has a hemolytic C5 level of approximately 0.5 per cent of normal. No C5 protein was detectable, but low levels of functional C5 activity could be found using a sensitive bactericidal assay. The proband's twin as well as another sister also had extremely low levels of hemolytic C5(approximately 0.5 per cent normal), but both these subjects have been healthy. Hemolytic complement and bacteriolytic activity could be restored by the addition of purified C5. No chemotactic activity for polymorphonuclear leukocytes could be generated in the C5-deficient serums upon activation of either the classic or alternative pathways, again demonstrating the importance of C5 in human subjects for the production of chemotactic factors. The chemotactic responsiveness of the patients' polymorphonuclear leukocytes and monocytes to preformed chemotactic factors was not depressed. Twenty-two of 32 other family members from three generations had depressed whole hemolytic complement levels. In 19 of 30 family members, levels of hemolytic C5 ranged from 13 to 64 per cent of normal. No linkage for C5 deficiency and the A or B loci of the major histocompatibility complex could be found. These data suggest an autosomal codominant mode of inheritance of C5 deficiency. Deficiency of C5 is compatible with good health, but it can be associated with repeated disseminated gonococcal infection.

4/5. Histologic documentation of gonococcal infection in the absence of a culturable organism.

    The high incidence of negative routine cultures, in the presence of suppurative involvement of a joint suggested a possible role for alternative diagnostic techniques. Bedside cultures with hypertonic and anaerobic media were utilized to evaluate synovium and synovial membrane in gonococcal arthritis. This is the first histologic documentation of the diagnosis of gonococcal arthritis in the absence of a culturable organism.

5/5. Alternative pathway complement activation:a possible mechanism inducing skin lesions in benign gonococcal spesis.

    In order to elucidate the pathogenesis of the skin lesions in 'benign gonococcal sepsis' direct immunofluorescence of an early macular lesion and routine histopathology of a mature papulopustular lesion in a patient with septic gonococcal dermatitis have been performed. Histopathology of the mature skin lesion revelaed a pattenr of 'allergic vasculitis'. Direct immunofluorescence showed exclusively deposits of C3 around and within the capillaries and in the basement membrane zone. No specific IgG, IgM, IgA or C4 deposits could be demonstrated. This, together with serological findings and reports from the literature, suggests an important pathogenetic function for complement, activated through the alternative pathway by means of gonococcal endotoxic lipopolysaccharide, in the pathogenesis of the skin lesions in benign gonococcal sepsis.
