A knowledge of the complement system in patients with collagen diseases is of interest as it may serve to indicate the existence of activity or non-activity in these diseases. We have studied the existence or non-existence of the activity of the complement system through evaluation of the levels of C3, as well as the implicated mechanism of the classical or alternate pathways through the measure of C'4 and C'3 proactivator components. Quantitation of complement components was obtained by electroimmunodiffusion, employing specific antiserum. From the results obtained, we observed that the complement activity in patients with SLE, the classic pathway was affected more (7 patients of the 24 studied), than the alternate pathway (3 patients). However, in those patients affected by sclerodermia, there seems to be an equal incidence of the activation of complement through both pathways (2 patients with activation through each way). Also of interest is the existence of a patient with SLE and another affected by sclerodermia in which a selective reduction of C'3 was observed. This observation suggests the possible existence of a selective destruction, perhaps mediated through a factor type such as the nephritic factor. However, there may exist other patients of whom we have already commented on, with a parallel reduction in the three components which suggests a change in the synthesis or in the simultaneous activation in both of the pathways. When realizing the comparative studies of the state in which the immunoglobulins (IgG, IgA and IgM) and complement components are to be found, the conclusion is that there is no significative correlation between the two. This is particularly interesting as it assumes the necessity of knowing the state of the complement and not only of the immunoglobulin, in order to know the state of activity in which the process is.
