The immunological responsiveness of a panel of 17 patients with systemic lupus erythematosus (SLE) was studied in an in vitro model of xenogeneic sensitization against mouse lymphoid cells. Generation of cytotoxic thymus-derived (T) cells evaluated by a chromium release assay against labeled target cells was found to be drastically impaired in these lupus patients. Such depression was independent of drug therapy at the time of the study, clinical status, and other immunological parameters such as antibodies against native DNA, complement levels, cryoglobulinemia, circulating immune complexes, or T- and bone marrow-derived (B)-cell numbers. In contrast to the cytotoxic response, the proliferative responses to phytohemagglutinin, to allogeneic lymphocytes, and to xenogeneic lymphocytes were not significantly different from those of normal individuals. The latter response was shown to be H-2 restricted with the primed lymphocyte test. These results suggest the presence of a selective defect in the generation or in the expression of killer cells rather than a deficiency in antigen recognition by T cells. The role of serum factor(s) was examined by educating the lymphocytes of normal subjects in the presence of serum from SLE patients. Such manipulation affected both the generation of killer cells and the proliferative response. Finally our observations indicate that depression of cell-mediated immunity in SLE patients may be associated with several mechanisms including a cellular one, specifically affecting the generation of killer T cells, and a humoral one possibly as a result of antilymphocytic antibodies and(or) immune complexes.

A patient with the discoid lupus erythematosus and lichen planus overlap syndrome has profound depression of serum C4 concentration associated with substantial mixed cryoblobulinemia. A family study failed to disclose evidence of a familial hypocomplementemia, cryoglobulinemia, or a dermatologic condition. Immunologlobulin, but no complement, was detected at the site of the skin abnormality. This case illustrates an immune-complex disorder with a mixed cryoglobulinemia that is related to immunoglobulin deposition in the skin.

Four patients with systemic lupus erythematosus (SLE) are described in whom there were major psychiatric complications. Two of these patients had cerebral lupus with psychiatric manifestations of the disease together with other features of disease activity and responding to treatment with high dose steroids. The first of these had had a ten-year history of recurrent episodes of depression before other features of the disease became evident; in the second patient recurrent psychotic episodes occurred after the onset of typical multi-system disease. The third patient had had a minor cerebro-vascular accident four years before other features of SLE became manifest, and cerebral deterioration later on in her life was probably due to hypertensive cerebro-vascular disease secondary to the renal disease of SLE. The fourth patient, a young man, had had recurrent episodes of depression and aggressive behaviour for several years and committed suicide at the age of 33.

A 23-year-old woman with SLE was admitted because of severe psychosis manifested by depression, delusions and the inability to perform minimal daily activities. The patient refused treatment with steroids, but was later convinced to try treatment with intravenous immunoglobulin (IVIG). Following treatment with IVIG a marked improvement was noted in her mental status and she was discharged. During a follow-up period of 18 months she resumed normal life; she does not receive any drugs currently and no psychiatric abnormalities have been noted. It is suggested that IVIG may be considered in the treatment of lupus cerebritis, especially when serious complications develop and other treatment modalities are ineffective.

Systemic lupus erythematosus is a multisystem autoimmune disease that may affect skin, joints, mucous membranes, heart, lungs, kidneys, nervous system and all the blood cell lines. Although its cause is unknown, abnormal immune function results in the formation of antibodies directed against various components of the human body (autoantibodies). Treatment depends of the severity of the illness and may include nonsteroidal antiinflammatory agents for arthritis; antimalarial therapy for skin disease and other mild lupus manifestations; and corticosteroids and immunosuppressive agents including azathioprine, cyclophosphamide, and methotrexate for more severe lupus manifestations. Persons affected by lupus and their families need help in understanding the condition and require support as they deal with fear, depression, and possible disability. Implications for nursing are varied and include patient/family education about medication, joint protection principles, energy conservation, pain and stress management, and coping techniques.

A synthetic peptide was used to develop an enzyme linked immunosorbent assay (ELISA) to detect antibodies to the ribosomal proteins P0, P1, and P2. Significantly increased levels of IgG antibodies to protein P were found in 16% (18/116) of patients with systemic lupus erythematosus but slightly increased levels were detected in 2% (2/98) of patients with rheumatoid arthritis and one normal control subject. No association was observed between the presence of IgG antibodies to protein P and either lupus psychosis or depression. Sequential studies in individual patients failed to show an association between antibody levels and the development of psychosis.

The influence of oestrogen on the lupus disease in MRL/l mice has been investigated. Adult, castrated male and female MRL/l mice were administered with s.c. injections of 3.2 micrograms of 17 beta-oestradiol twice a week. The results clearly demonstrate that a relatively small dose of oestrogen is a potent accelerator of the lupus disease in this mouse strain. Thus, administration of oestrogen accelerates glomerulonephritis, lymphoproliferation and mortality. Our results also indicate that oestrogen exerts a dual effect on the immune system of MRL/l mice by depression of antigen-specific and mitogen-induced T cell responses as well as enhancement of polyclonal B cell activation and autoantibody formation. In addition, even short-term administration of oestrogen in the preclinical phase of the disease resulted in long-lasting effects as evaluated by reduced longevity and aggravation of renal disease.

A retrospective study of all patients with systemic lupus erythematosus (SLE) who died at the University Hospital of the West Indies over a 14-year period is presented. The major cause of death was infection followed by renal failure. Gram-negative organisms were the major microbiological agents causing infections. Side-effects of therapy were common, in particular bone marrow depression and haemorrhage related to anticoagulants. It appears that controlling severe lupus activity without increasing the risk of lifethreatening complications remains an important goal in the treatment of SLE.

Captive gray wolves (Canis lupus) were immobilized (loss of consciousness) with 2.0 mg/kg xylazine hydrochloride (XYL) and 0.4 mg/kg butorphanol tartrate (BUT) administered intramuscularly. Induction time was 11.8 +/- 0.8 min (mean +/- SE). Immobilization resulted in bradycardia, respiratory depression, and normotension. Fifteen min after induction, six wolves were given either 0.05 mg/kg naloxone hydrochloride (NAL) and 0.125 or 0.250 mg/kg yohimbine hydrochloride (YOH), or an equal volume of saline (control) intravenously. Antagonism resulted in shortened recovery times compared to control animals (P less than 0.03); there was no difference in recovery times between the YOH doses (P greater than 0.05). Antagonism caused increases in heart rate (HR) and respiratory rate (RR), but no changes in MABP. Eight other wolves were similarly immobilized, but given only NAL. This resulted in partial antagonism with the animals appearing to be sedated with XYL only. Three wolves given only 0.4 mg/kg BUT assumed a state described as "apathetic sedation." Three other wolves sedated with only 2.0 mg/kg XYL showed a profound sedation characterized by recumbency, bradycardia and shallow, but regular, respiration. This study demonstrated that (1) BUT and XYL together, but not separately, can completely immobilize wolves, (2) this combination can be rapidly antagonized by NAL and YOH, and (3) there appeared to be no adverse cardiopulmonary reactions to any of the drugs used.

The authors report the case of a 26 year old non-migrainous man who presented over a 5 week period with a cluster of classical migrainous attacks associated with CSF lymphocytosis. The association of this type of CSF response with attacks of migraine is unusual; in migraine the CSF is normal or may show an isolated increase in protein content (with the exception of the very rare familial hemiplegic migraine). In the reported case, other conditions liable to give rise to migraine and CSF lymphocytosis having been excluded (acute DLE, brucellosis...), this association corresponded to a benign and spontaneously regressive condition, possibly a migraine symptomatic of benign acute lymphocytic meningitis. The authors suggest that a primary meningeal inflammation may have been the cause of the cluster of migraine attacks which in this case were more accompanied perhaps because they induced a wave of depression of cortical activity.
