Familial deficiency of two subunits of the first component of complement. C1r and C1s associated with a lupus erythematosus-like disease.
Complete absence of C1r and almost complete absence of C1s were found in 4 of 8 living siblings. Two of the 4 suffer from a syndrome that combines discoid lupus erythematosus and nondeforming rheumatoid-like arthritis; one of the siblings has mild nephritis. The other 2 C1 deficient family members are clinically well. Evidence from this and other families suggests that deficiency of C1 components or C4 is associated with higher risk of developing a lupus-like disease than is deficiency of C2.
Phenolic glycolipid-1 from M. leprae inhibits oxygen free radical production by human mononuclear cells.
We studied the effect of PGL1, a phenolic glycolipid unique to Mycobacterium leprae, on the activation of the phagocyte oxidative respiratory burst, by measuring the chemiluminescence (CL) generated by normal mononuclear cells. PGL1 induced a decrease in oxygen free radical production stimulated by mycobacteria (M. leprae, BCG and M. kansasii) or by phorbol myristate acetate, but did not prevent the binding or ingestion of fluorescein-conjugated mycobacteria. In contrast, mycoside A from M. kansasii, a structurally related compound, did not alter the CL response. In addition, treatment of M. leprae with anti-PGL1 antibodies failed to restore the response to this microorganism. PGL1 could act as an oxygen species scavenger and protect M. leprae from killing by toxic oxygen metabolites.

[Prospective evaluation of the risk of congenital toxoplasmosis. II. Further data on the immune response during pregnancy].
The indirect immunofluorescence test was carried out in 500 pregnant women in urban and rural areas, with a view to following conversion to seronegative values. The evolution of the immune background in infection with T. gondii was followed up by comparative analysis of the seroepidemiological data obtained in 1976 and 1977. It was found that:--Variations in the intensity of endogenous and exogenous factors bring about changes in the frequency and intensity of the immune response in toxoplasmosis.--Postnatal evolution of the child can be correlated with the age of pregnancy when seroconversion accurred and with the intensity of the latter.--The predominance of seroconversion in the 6th and 7th month of pregnancy and negativation of some of the responses during pregnancy suggest the need of an additional serological control during these months.--The effect of optimal conditions during springtime resulted in seasonal appearance of seroconversions, offering an additional orientation.--In the neonates of seropositive mothers no cases of manifest disease were observed; the presence of infection has to be subsequently confirmed or invalidated.
