RESUMO
OBJECTIVE: Synthetic glucocorticoids cause various psychiatric symptoms. Prescription of psychotropic drugs could be considered to be a proxy for manifestation of psychiatric symptoms. The aim of this study was to investigate the prescriptions of psychotropics in outpatients receiving synthetic glucocorticoids. METHODS: We used the claims sampling data during January 2015 from the National Database of Health Insurance Claims and Specific Health Checkups of Japan made by the Ministry of Health, Labor, and Welfare in Japan. We compared the prescription rates of psychotropics between outpatients receiving oral synthetic glucocorticoids and age- and sex-matched controls and the prescription rates of psychotropics among the eight dosage groups of synthetic glucocorticoids by chi-squared test, and chlorpromazine/imipramine/diazepam equivalent doses (or daily defined doses) of respective psychotropics among these groups using Welch's t-test. RESULTS: Synthetic glucocorticoids were prescribed to 3.1% (n = 18 122) of 581 990 patients. The prescription rates of psychotropics were significantly higher among the synthetic glucocorticoid recipients than among the non-recipients: antipsychotics, 1.8% (n = 321) vs. 1.1% (n = 201) (P = 1.4 × 10-7 ); antidepressants, 4.0% (n = 724) vs. 2.0% (n = 359) (P = 8.7 × 10-30 ); anxiolytics/hypnotics, 16.7% (n = 3029) vs. 10.2% (n = 1841) (P = 2.7 × 10-75 ); and mood stabilizers, 1.3% (n = 238) vs. 0.7% (n = 120) (P = 3.6 × 10-10 ) respectively. There was no significant difference in the prescription rates of any psychotropic drugs, other than anxiolytics/hypnotics, among the eight synthetic glucocorticoid dosage groups. CONCLUSION: Prescriptions of oral synthetic glucocorticoids were found to be associated with the use of any of the types of psychotropic drugs, other than anxiolytics/hypnotics, although a causal relationship could not be confirmed due to the retrospective and cross-sectional nature of this study.

The Fas ligand is predominantly expressed in activated T lymphocytes and is one of the major effector molecules of cytotoxic T lymphocytes and natural killer cells. Previously, we found excessive apoptosis of epithelial cells and infiltrating lymphocytes expressing Fas ligand mRNA in the lung tissue of bleomycin-induced pulmonary fibrosis in mice. Here we demonstrated that the administration of a soluble form of Fas antigen or anti-Fas ligand antibody prevented the development of this model and that lpr and gld mice were resistant against the induction of pneumopathy. These results suggest that the Fas-Fas ligand pathway plays an essential role in the development of pulmonary fibrosis and that preventing this pathway could have therapeutic value in lung injury and fibrosis.

Acute graft-versus-host disease (aGVHD) is a major complication following allogeneic bone marrow transplantation (BMT). Recently, accumulating evidence indicates that the Fas/Fas ligand (FasL) system is implicated in the pathogenesis of aGVHD in murine models. We determined the serum levels of soluble FasL (sFasL) in BMT recipients using an enzyme-linked immunosorbent assay. The serum sFasL was suppressed during the period of myelosuppression following the preparative regimen and subsequently increased with hematopoietic reconstitution after BMT. In patients with aGVHD, the serum sFasL level was significantly higher than in those without aGVHD. In the mixed lymphocyte reaction assay, sFasL in the supernatants was increased with a significant correlation to the level of 3H-thymidine uptake. Our findings suggest that the Fas/FasL system is activated by allogeneic stimulation and may have close correlation to the development of aGVHD in human BMT.

Multiple myeloma is characterized by the accumulation of malignant plasma cells in the bone marrow and rarely cured by chemotherapy. Villunger et al. showed that the neoplastic plasma cells express Fas ligand (FasL), which transmits a signal of apoptosis upon ligation to Fas, and suggested that the FasL suppresses the T-cells activated against malignant cells, resulting in escape from tumour immunity. We examined serum soluble FasL (sFasL) levels in 35 multiple myeloma patients to evaluate the correlation between sFasL levels and clinical characteristics. The serum sFasL levels were not affected by the disease status, serum monoclonal protein levels, or other prognostic factors. We could not determine whether the expression of FasL is involved in the poor clinical course of the disease.

Fas-ligand (FasL) is a member of the tumor necrosis factor family and transmits apoptotic cell death signal by binding to its receptor, Fas. FasL is expressed on the cell surface of activated T-cell and natural killer (NK) cell. It has been shown that the FasL can be released from the cell surface by metalloproteinase. The serum soluble FasL (sFasL) is increased in some patients with NK cell lymphoma/large granular lymphocytic leukemia. We have recently seen a patient with recurrent B-cell lymphoma accompanied with an increased serum sFasL level after autologous peripheral blood stem cell transplantation. The sFasL was markedly decreased with the tumor regression induced by the chemotherapy. We present here the first case of an elevated serum sFasL level associated with B-cell lineage malignancy and discuss the possible clinical value of sFasL.

Fas ligand (FasL) is a type II membrane protein. Binding of FasL to its receptor, Fas, induces apoptosis. Matrix metalloproteinase cleaves the membrane-bound human FasL to yield the active soluble form. Here, we have produced a large amount of human soluble rFasL using the yeast, Pichia pastoris. The purified rFasL was found to be glycosylated and to exist as a trimer. The rFasL was effective in inducing apoptosis in a Fas-expressing T cell or a fibroblast cell line. The ID50 of rFasL for mouse Fas-expressing T cells was about 0.5 ng/ml. The killing process with rFasL was quick. That is, >80% Fas-expressing mouse cells were killed within 1 h by a saturation concentration of human rFasL. Intravenous administration of 500 microg of human rFasL had a lethal effect in mice. When the mice were pretreated with Propionibacterium acnes, the subsequent injection of 30 microg of human rFasL induced hepatic failure and killed the mice within 24 h. These results indicated that the soluble human FasL is active in inducing apoptosis in vitro and in vivo, and its deleterious effect may be strengthened in patients who are suffering from bacterial infection.

By histopathologic examination of various organs in 3 normal strains, C3H/HeN, ICR, and DBA/1J, of mice treated intravenously once with anti-Fas antibody (Jo2), we failed to determine any target organ, except the liver, responsible for the acute lethality induced by the Fas/anti-Fas antibody interaction. However, we could show the presence of Fas-mediated apoptosis in other organs aside from the liver and normal mouse strain differences in susceptibility to anti-Fas antibody. Among these strains, C3H/HeN was the most susceptible to the antibody, followed by ICR and DBA/1J. We observed Fas-mediated apoptosis in the liver, spleen, thymus, lymph nodes, Peyer's patch, intestine, skin, coagulation glands, ovary, uterus, and vagina in all 3 strains and additionally in the epididymides and seminal vesicles in the DBA/1J strain. We also demonstrated that Fas-mediated apoptosis of small lymphocytes in the mantle zone of splenic lymphatic follicles preceded that of the hepatocytes or thymic cells. Since cellular damage was most severe in the liver among all the apoptotic organs in the 3 mouse strains, liver injury induced by anti-Fas antibody is speculated to play a significant role in the death.

Several anti-Fas ligand (FasL) inhibitory mAb (FLIM) were raised and characterized in this study. One, FLIM58, showed more potent neutralizing activity than Fas-Fc, the previously established artificial neutralizing agent for FasL. Several murine models of acute graft-versus-host disease (GVHD) after allogeneic bone marrow transplantation have been used to show that both FasL and perforin, the major effector molecules of cytotoxic T lymphocytes, are involved in this disease. In our GVHD model, FasL rather than perforin was associated with lethality. Administration of FLIM58 or Fas-Fc reduced the weight loss and mortality caused by GVHD, although other signs of GVHD, such as skin lesions, lymphoid hypoplasia and mononuclear cell infiltration in the liver, did not improve significantly. FLIM58 was more effective than Fas-Fc in reducing mortality. Our results demonstrated that neutralizing agents for FasL are therapeutic for lethal GVHD.
