Detection of basement membrane zone antigens and C3 fragments in the blister fluid of bullous pemphigoid.

In polyacrylamide gel gradient electrophoresis, serum and blister fluid of patients with bullous pemphigoid showed a nearly identical protein distribution pattern except for one more concentrated fraction in the blister fluid. This fraction could be isolated by several gel chromatographic steps and then be characterized as a protein with a molecular weight of 240,000 (BFP 240,000) consisting of several subunits. Two of these subunits could be identified as C3 fragments and two other ones as basement membrane zone antigens (BMZ-Ag) by means of a modified Laurell technique. The molecular weight of the BFP 240,000 may be small enough to allow it to penetrate through the vessel wall into the blood circulation where, with the BMZ-antibodies (BMZ-Ag-BMZ-Ab-complexes can be formed. The occurrence of such immune complexes in the serum has been shown in a previous paper.

[Detection of intercellularsubstance-autoantibodies after antigen-antibody-complex splitting in pemphigus foliaceus (author's transl)].

One patient suffering from pemphigus foliaceus exhibited the typical intercellular deposits of immunoglobulins in the subcorneal layers of the affected and not affected skin by direct be detected by means of several antigensubstrates. They could only be found after splitting of the antigen-antibodies-complexes. The laboratory findings exclude a more distinct deviation of the humoral and cellular immune reactivity.

[Impetigo herpetiformis and PUVA-treatment (author's transl)].

Report on a 20 years old pregnant woman, who fulfilled the criteria of the impetigo herpetiformis as well as later those of the pustular psoriasis Zumbusch in her clinical course. The impetigo herpetiformis is interpreted as a variant of the pustular psoriasis occurring during the pregnancy with lowered calcium-level, which increases the endogeneous eruption pressure. After negative attempts of treatment with Prednisolon, antibiotics, and later with Methotrexat an excellent therapeutic effect could be achieved by oral PUVA-treatment.

Detection of antibodies after immune complex splitting in serum of patients with bullous pemphigoid and systemic lupus erythematosus.

No free anti-basement membrane antibodies were found in the sera of four patients with bullous pemphigoid, and no free anti-DNA antibodies in the sera of two patients with systemic lupus erythematosus. The sera treated with 3 mol/l urea and by gel chromatography to separate these antibodies from any circulating complexes, and antibodies to basement membrane were detected by immunofluorescence and to DNA by the Farr technique. The appropriate antibodies were found in all the sera, indicating that failure to detect antibodies by routine procedures may be due to binding of the antibodies to soluble antigens forming complexes in the sera.
