We examined 104 patients divided in two groups: patients suffering from lupus erythematosus systemic (SLE) and from lupus erythematosus cutaneous (CLE). Cellular immunity tests in vivo were performed in all patients: DNCB, PPD, Trichophytin, Candidin. Cellular immunity response were compared according to undergoing steroid therapy. Patients suffering from CLE had decreased reaction to cellular immunity test with increased dose of steroid therapy. In patient with SLE this decrease was not recognised.

A 10-year-old girl with lupus vulgaris following single BCG vaccination is reported. She had a 15 x 20 cm painless lesion covering her left shoulder, axilla, triceps and biceps region. PPD test was positive. Histopathological picture was identical to lupus vulgaris.

Blood mononuclear cells from 20 lupus patients were cultured in the presence of nucleosomal antigens to determine whether they induce lymphocyte proliferation. The predominant effect seen, however, was one of inhibition of the background proliferation. Such inhibition was rare with cells from female or male controls. Nucleohistone (NH), crude histone and enriched preparations of histones H2A/H4, H2B and H3 showed this effect in approximately one-third of patients, but H1 and single-stranded (ss) DNA had no such activity. Double-stranded (ds) DNA may show this inhibitory action, but further tests are required. ssDNA was the only antigen that showed evidence (two patients) of disease-related stimulation of proliferation. Histones and NH induced proliferation in many subjects but the strongest responders were controls. Patients responded poorly to tuberculin PPD but gave an exceptionally strong proliferative response to pokeweed mitogen. It is suggested that the inhibition of background proliferation in patients is a consequence of the interaction of nucleosomal antigens with sensitised T cells. If T cell sensitisation to histones is an important factor in the development of lupus, the disease may be preventable in those at risk by inducing tolerance to the appropriate peptides.

The purpose of this report is to provide suggested guidance concerning the monitoring of TNF blocker therapy. Since the completion of randomized trials, several new long-term safety concerns have arisen, involving mycobacterial and opportunistic infections, cytopenias, lymphoma, demyelinating disease, drug-induced lupus, congestive heart failure and hepatotoxicity. Since these serious events are rare, widespread post-marketing use and prolonged follow-up have been required to analyze their prevalence. Monitoring of TNF inhibitors is necessary to reassure physicians and patients of the continued efficacy and safety of these drugs. No published recommendations on monitoring are available. The clinician must weigh the potential clinical benefits of TNF inhibition against potential adverse effects. Patients should be evaluated carefully for the risk or presence of infection, tuberculosis and other serious adverse events by regular visits, careful clinical assessments, and an assiduous, high index of suspicion for these rare events. Tuberculin skin testing using PPD is recommended before starting treatment with any TNF inhibitor.

Up to now, there have been few reports concerning changes in lupus activity and immune indices of tuberculosis in patients with systemic lupus erythematosis (SLE). A retrospective investigation was given to survey the case data of SLE patients companied with tuberculosis that were treated in our hospital from 2001 to 2010 and compared with that of sex- and age-matched patients with single SLE. Changes in autoantibodies, lupus activity, inflammatory indices, positive rates of tuberculin (PPD) test and tuberculosis antibody (TB-Ab) of both groups were observed. It was indicated by results that ANA antibody level and positive rates of anti-Sm, anti-SSA and anti-SSB antibodies were significantly lower in the TB group than those in the control group (P < 0.05); C3 and C4 levels were significantly higher in the TB group than those in the control group; damage of hematological system (predominantly platelet) was less severe in the TB group than that in the control group (P < 0.05); no significant differences in IgG, IgM and IgA were noted between two groups (P > 0.05); ESR, C-reactive protein and LDH levels were significantly higher in the TB group than those in the control group (P < 0.05); PPD-IgG were significantly higher in the TB group than those in the control group (P < 0.05). These results suggested that after SLE patients were infected with tuberculosis, immune function was altered and lupus activity was inhibited as well.
