Long-term follow-up investigation of the effects of the biopsychosocial approach (BPSA) to bronchial asthma.

The recent rapid increase in the number of allergic patients is becoming a social problem. Studies of the causes of this phenomenon involve various fields, with much attention focused on finding new antigens in food, air, articles encountered in daily living, etc. Recent studies of psychoneuroimmunology (PNI) also suggest a strong influence of emotions on allergic reactions. The number of allergic patients is increasing in all civilized countries without exception, and the stress prevalent in modern civilized society is related to this increase. Modern allergology does not yet have sufficient countermeasures for such stress states. We applied a biopsychosocial approach (BPSA) to treatment programs for allergic disease, incorporating treatment of physical and psychosocial problems en bloc. We studied the long-term effects of BPSA therapy on 82 patients who were treated for more than 3 months in the hospital and were examined 2 to 3 years after discharge. Results showed that more than 80% of patients maintained improvement and 45% of those with intractable asthma were able to withdraw from steroid hormones. BPSA achieved better results than those with standard medication administered only to the body. Improvements after treatment included physical changes, normalization of MV (microvibration) type, decreased levels of plasma histamine, and normal circadian rhythms of lymphocyte subsets. These changes reflect part of the physical mechanisms by which BPSA improves asthma symptoms. From a psychological view point, the patients' feelings, personal relations, behavior, etc. were changed after BPSA, allowing a new life style and improved QOL. It is important for asthma patients to maintain good overall condition over long periods. After BPSA, 80% of our patients were able to do so. It is difficult for the therapist to approach asthma from different aspects at once, including biological, psychological, and social, so we developed a five-stage program of BPSA therapy and found that this obtained favorable results.

[Control of graft-versus-host disease and infection associated with immunosuppression].

Graft-versus-host disease (GVHD) in leukemia patients following allogeneic bone marrow transplantation (BMT) has a lot of demerits but it also has a merit, namely graft-versus-leukemia effect. We reported the results of our recent trials on prevention, treatment and induction of GVHD, and prevention of viral infection after BMT. The results were as follows: 1) Twenty-four percent of patients who received prophylactic administration of cyclosporine and short term methotrexate still developed II degree-IV degree acute GVHD. 2) Patients with I degree or II degree acute GVHD showed good clinical courses. But, most patients with III degree GVHD gradually developed chronic GVHD. All patients with IV degree GVHD died of GVHD or infection. 3) Mizoribine and deoxyspergualin were effective for steroid-resistant GVHD. 4) Bestatin was administered to recipients who did not develop GVHD until day 30 after BMT. An interim report suggests that bestatin may induce chronic GVHD and suppress the relapse of leukemia. 5) Oral administration of gamma-globulin may prevent viral enteritis. Intravenous administration of anti-cytomegalovirus monoclonal antibody may prevent cytomegalovirus pneumonia.

[Augmentative effect of sizofiran on the immune functions of regional lymph nodes in patients with cervical cancer].

Twenty mg of sizofiran (Schizophyllum glucan: SPG) was i.m. administered one day prior to surgery, or the same dose was injected 8 days and one day before surgery to 40 patients with cervical cancer and 15 with a benign tumor. Frozen sections of fresh pelvic lymph nodes from these patients obtained during surgery were stained by the ABC (Avidin-biotin-peroxidase complex) method with several monoclonal antibodies to define the surface phenotype of mononuclear cells. SPG led to a great increase in the number of cells stained with interleukin-2 receptor (IL-2R) and Leu 3a antibodies, mainly in PC, but with only a slight increase in the number of cells stained with Leu 2a, 7, 11, and M3 antibodies. This augmenting effect was more prominent in patients receiving two SPG injects that in those with a benign tumor. These results suggest that stimulus with some antigen (cancer antigen in the present study) may be required to induce immuno-augmentation by SPG which has no antigenicity. Interestingly, the above augmenting effects could be seen even in metastatic lymph nodes from advanced cervical cancer patients. SPG was thus revealed to be a potent biological response modifier leading to augmented helper T (Th) cell functions of pelvic lymph nodes in cervical cancer patients, among which an enhanced IL-2/IL-2R system was noted.

[Early phase II study of MST-16 (sobuzoxane) on malignant lymphoma].

Early phase II study of MST-16[4,4-(1,2-ethanediyl) bis (1-isobutoxycarbonyloxy-methyl-2, 6-piperazinedione], a derivative of ICRF-154, on malignant lymphoma was conducted by multi-institutional cooperative group. MST-16 was administered orally at doses of 1,600 mg/body/day for 5 days or 1,200 mg/body/day for 10-14 days, mainly. The number of registered and evaluated patients were 29 and 28, respectively (Hodgkin's disease 3 patients and non-Hodgkin lymphoma 25). Twenty-seven of 28 patients had received prior chemotherapy and/or radiation therapy. Of 28 evaluable patients, overall response rate (CR + PR) was 32.1%. In high-dose administration group, the response rate was not significantly high. The response rate seemed to be high in patients who were treated repeatedly (number of courses greater than 3). Major side effects observed were myelosuppression and gastro-intestinal disorders which were reversible in a rest period. Myelosuppression seemed to be severe in high-dose administration group. This study indicated that MST-16 was a useful agent against malignant lymphoma including primary resistant or relapsed patients, and that the recommended regimen for a late phase II study was considered to be 1,600-2,400 mg/body/day for 5-7 days repeatedly with a pause of several days. Furthermore, the study should be considered at the dose of 3,200 mg/body because half cases administered at this dose showed some response.

[Effective continuous intraarterial chemotherapy for a patient with FIGO stage IIIb cervical adenocarcinoma invasing the bladder wall].

A patient with FIGO stage IIIb adenocarcinoma of the uterine cervix (moderately differentiated, endocervical type) underwent an exploratory laparotomy because of a direct cancer invasion to the bladder wall, and then she was treated with consecutive intraarterial (IA) CDDP (10 mg/day) combined with continuous IA 5-FU (250 mg/day). Six weeks after, CR (complete response) was obtained by this IA chemotherapy (total dose; 5-FU: 10,500 mg, CDDP: 300 mg). Further 5-weeks-IA chemotherapy was added to keep the "CR" effect (final total dose; 5-FU: 19,250 mg, CDDP: 500 mg). The only toxic sign was a mild nausea. The patient's PS (performance status) was 0 (normal activity) and thereafter she could undergo a "curative" radical hysterectomy. The cancer invasion to the bladder wall observed at the first exploratory surgery completely disappeared histologically as well as macroscopically. In obtained material, small "viable" cancer focus was found in the cervical canal but the margin was free, and all nodes were negative. Postoperatively, the patient has receiving a continuous IA 5-FU (125 mg/day) for 13 months as a maintenance and she is free of disease (NED) with a normal activity (PS = 0). The present treatment modality is considered to be promising for advanced cervical adenocarcinoma having a poor prognosis due to its low sensitivity to radiotherapy.

Multiplicative effect of hyperpepsinogenemia I and non-secretor status on the risk of duodenal ulcer in siblings.

In a search for genetic markers of duodenal ulcer, serum pepsinogen I level, ABO blood groups and secretor status were determined in 89 siblings of 34 duodenal ulcer families. Duodenal ulcer patients were likely either to have hyperpepsinogenemia I or to be non-secretors on a familial basis, but not to have an increased frequency of blood group O. The frequency of duodenal ulcer in the siblings was highest in hyperpepsinogenemia I/non-secretor and lowest in normopepsinogenemia I/secretor. Therefore, the influence of two genes, hyperpepsinogenemia I and non-secretor, on the risk of duodenal ulcer is multiplicative. These results provide evidence on the hypothesis of polygenic inheritance of duodenal ulcer.

Prevention of immunosuppression in stressed mice by neurotropin(NSP).

It is well known that the immune function can be compromised by stress. To investigate immune function in mice stressed by experimental restraint or unavoidable and opioid dependent stress, we evaluated the changes in total body weight and in organ weights (liver, spleen and thymus) of these animals, as well as the phagocytic activity of macrophages, the cytotoxicity of T cells and inhibitory effects on tumor growth and changes in T cell subset populations. At the same time we evaluated the effects of Neurotropin (NSP), a substance extracted from the inflamed skin of rabbits inoculated with the vaccinia virus and which appears to possess neuroimmunomodulating activity. The experimentally stressed group exhibited a reduction of phagocytic activity of macrophages, cytotoxicity of T cells and inhibitory effects on tumor growth. In addition there were changes in the population of T cell subsets. In those animals pretreated with NSP, the immunosuppression induced by stress was ameliorated. As compared with several agents which influence phagocytosis, neurotropin exhibited effects similar to that of agents that blocked the adrenaline receptor and an opioid antagonist rather than tranquilizer (diazepam) and a cholinergic receptor blocker. The pharmacologic effects of neurotropin support a relationship between the actions of the central nervous system and the immune system.

[Evaluation of UFT administration in patients with ovarian cancer who had no evidence of disease after the initial therapy].

Twenty nine patients with ovarian cancer of common epitherial origin who had no evidence of disease proved by computed tomography after the initial operation and chemotherapy were studied. The patients were randomized into two groups; (A) administration of UFT (1-(2-tetrahydrofuryl)-5-fluorouracil mixed with uracil) orally at a daily dose of 300 mg, 12 cases, (B) no further therapy, 17 cases. The therapeutic efficacy of UFT was assessed pathologically at the second look laparotomy (SLL). Plasma levels of 5-FU, tegafur and uracil were determined once a month to check whether patients intake UFT regularly or not. There were no significant difference in the mean age, in the distribution of numbers of patients in FIGO stage and histological cell type, in the mean total doses of CDDP and doxorubicin given at the initial chemotherapy [CDDP: (A) 352 +/- 152 mg, (B) 464 +/- 192 mg, doxorubicin: (A) 118 +/- 76 mg, (B) 119 +/- 92 mg] and in the duration between the initial operation and the SLL [(A) 484 +/- 154 days, (B) 414 +/- 274 days] between the two groups. The mean periods in the administration of UFT were 484.3 +/- 154 days. Recurrence was identified at the SLL in 1 case (8.3%) at paraaortic lymph nodes in (A) and 3 cases (17.6%) at the mesenterium, cul-de-sac and ascitic fluids in (B). No significant difference of recurrence ratio was observed between the two. Further long-term observation is required to assess the advantage of administration of UFT.

[A study on the improvement of denture base resin. Epoxy dimethacrylate-polybutadiene dimethacrylate-MMA monomers as the liquid of denture base resin].

The dimethacrylates, EpDMA and BdDMA, which have a bisphenol type epoxy chain and butadiene chain in their main chains, respectively, were synthesized. The properties of the terpolymer composed of EpDMA, BdDMA and MMA monomers were examined. The monomer mixture of EpDMA, BdDMA and MMA was used as the liquid of denture base resin, and the properties of the cured resin were examined. The polymerization shrinkage of the terpolymer of EpDMA-BdDMA-MMA decreased with the increase in the EpDMA concentration in the cured resin, and the transverse strength and the elastic modulus were greatest at the BdDMA concentration of 0.3-1 vol%. The denture base resin produced using a monomer mixture as the liquid, the transverse strength and the impact strength showed the highest values of about 110 MPa and 14 KJ/m2, respectively, at the liquid composition of 10 vol% EpDMA, 1 vol% BdDMA and 89 vol% MMA.

[Antigenic phenotype of the lymphocytic component of regional lymph nodes in patients with cervical cancer and its modulation by lentinan].

Immunohistochemical study with various monoclonal antibodies to the mononuclear cell surface antigens was carried out on the regional lymph nodes in patients with cervical cancer to assess the augmentative effect of lentinan. Zero, 2, 4, or 6 mg of lentinan was administered i.v. one day prior to surgery to patients with cervical cancer (14 cases with FIGO stage 0 and 19 with FIGO stage Ib) and those with benign gynecologic tumors (8 cases with myoma uteri and 6 with ovarian tumor). Frozen sections of fresh pelvic lymph nodes obtained from these patients during surgery were stained by the ABC (avidin-biotin-peroxidase complex) method using several monoclonal antibodies to define the surface phenotype of mononuclear cells. The results were as follows: 1. Pelvic lymph nodes in patients with benign disease: In the absence of lentinan, lymphocytes stained with Leu 3a antibody were more numerous than those stained with Leu 2a, and both were observed mainly in the paracortical area (PC). The number of lymphocytes stained with Leu 4 antibody was practically equal to the sum of those stained with Leu 3a and Leu 2a. HLA-Dr positive lymphocytes were present in moderate numbers in PC and sinus. The above findings were not changed by the administration of lentinan. Cells stained with monoclonal antibodies including Leu 7, 11, M3, and IL-2 receptor (IL-2R) were very few or absent. 2. Pelvic lymph nodes in patients with cervical cancer receiving no lentinan: The findings obtained in these cases were much the same as those in patients with benign tumors.(ABSTRACT TRUNCATED AT 250 WORDS)

[Effect of sizofiran or recombinant interferon gamma on the activation of human peritoneal macrophage function; an approach for the prophylaxis of intraperitoneal recurrence of ovarian cancer].

Sixty-two patients with gynecological disease, who were treated with sizofiran (SPG) intramuscularly before laparotomy or with recombinant interferon gamma (IFN) intraperitoneally on the day of the laparotomy, were studied to investigate the change on the number and function of peritoneal macrophages (PM) obtained by peritoneal washing on the day and on the 1st and 4th days after the laparotomy. SPG significantly increased the number of PM by the 1st day, and IFN by the 4th day (p less than 0.05). However, IL-1 and IFN-gamma secretion by PM were not activated by SPG or IFN treatment, respectively. When patients were treated with these two agents simultaneously, the number of PM was significantly increased by both the 1st and the 4th day (p less than 0.05), and IL-1 and IFN-gamma secretion by PM were also significantly activated by the 1st day (p less than 0.05). These data suggest that SPG and IFN had a synergistic effect on increasing the number of PM and on activating the secretion of cytokines by PM, and that the priming with SPG played an important role in the activation of PM function by IFN.

[Sizofiran and recombinant interferon gamma stimulate peritoneal macrophages obtained from patients with gynecologic malignancies--increased secretion of tumor necrosis factor, IL-1 and interferon-gamma].

TNF, IL-1, IFN-gamma and PGE2 secretion of peritoneal macrophage obtained by peritoneal washing at the first day after laparotomy from 19 patients with cervical cancer and 19 with ovarian cancer, who were treated with sizofiran (SPG) intramuscularly before laparotomy or with recombinant interferon gamma (rIFN) intraperitoneally at the day of laparotomy, were studied. Treatment with SPG and rIFN significantly increased the number and secretion of TNF, IL-1 and IFN-gamma (p less than 0.05) but not that of PGE2. A high correlation between secretion of TNF and IFN-gamma (r = 0.99, p less than 0.01) was observed. These data suggest that potent tumoricidal activity of peritoneal macrophage obtained from the patients with gynecological malignancies could be expected by the treatment with SPG and rIFN due to the increased secretion of TNF, IFN-gamma and IL-1 and inhibition of increased secretion of PGE2.

Effective therapy with low dose of oral cyclosporine A and prednisolone for alopecia universalis.

Although alopecia universalis is an incurable disease, we have obtained favorable results using a low dose of 2.5 mg/kg of cyclosporine A and 5 mg/day of prednisolone without adverse effects. We report our clinical experience of the treatment of two cases of alopecia universalis. Immunological examinations showed marked changes in the ratio of T cell subsets in peripheral blood. There was an increase of OKT8 positive cells and NK cells, reduction of IL-2R positive cells. These immunological changes following recovery from alopecia suggest a correlation between immunological disorders and the pathogenesis of this disease (alopecia universalis).

[Pulmonary infiltration with eosinophilia possibly induced by cefotiam in a case of steroid-dependent asthma].

A 37-year-old female with refractory asthma taking betamethasone orally (1 mg/d), showed a fever of 38.5 degrees C, productive cough and dyspnea. The chest X-ray demonstrated diffuse infiltration in the left lower lung field. The WBC count was 16,000/mm3 with 6% eosinophils. She was treated with intravenous drip infusion of antibiotics (Cefotiam 2 mg/d and Sisomicin 150 mg/d) for 2 weeks, and her symptoms and the chest X-ray findings improved. However, at the end of the therapy eosinophilia was noticed. Sixteen days after the completion of antibiotic therapy, she again experienced fever, cough and dyspnea. The chest X-ray again demonstrated diffuse infiltrations in the left lower lung field. The total IgE level, histamine and circulating immune complex titers were elevated. The WBC count was 14,700/mm3 with 34% eosinophils. Although a sputum culture yielded no organisms, many eosinophils were observed in the sputum. There were no clinical or laboratory findings compatible with allergic broncho-pulmonary aspergillosis. After the administration of oral prednisolone (40 mg/d), the patient showed rapid improvement with resolution of all symptoms and normalization of the IgE, histamine and circulating immune complex levels. The chest X-ray revealed marked regression of the pulmonary infiltrations. A microscopic examination of a transbronchial biopsy specimen demonstrated moderate eosinophilic infiltrations. It was compatible with the diagnosis of pulmonary infiltration with eosinophilia. Treatment was performed with prednisolone. The result of a lymphocyte stimulation test was positive for Cefotiam. An in vitro test was performed to evaluate the diagnosis of drug allergy in this case.(ABSTRACT TRUNCATED AT 250 WORDS)

[Stump recurrence after radical hysterectomy for patients with uterine cervical cancer].

Of a total of 1,025 cases of radical hysterectomy for histological squamous cell carcinoma (543 stage I cases and 482 stage II cases), we examined 50 cases of recurrence of the carcinoma (4.9 percent; 24 stage I cases and 26 stage II cases) at the site of the vaginal stump. The percentage of recurrence at the site of the vaginal stump was significantly higher in stage I and stage II cases, in which metastases to the lymph nodes or vascular invasion was observed (p less than 0.01). The length of vagina excised during the radical hysterectomy was measured and its relationship to recurrence at the site of the vaginal stump was investigated. In stage I cases that did not exhibit metastases to the lymph nodes, the shortest vaginal length excised in cases with a positive recurrence at the site of the vaginal stump was 2.5 +/- 0.9 cm; the shortest vaginal length in cases with a negative recurrence at the site of the vaginal stump was 1.8 +/- 0.8 cm. A significant difference (p less than 0.05) was observed between them. Furthermore, in stage I cases with no metastases to the lymph nodes, one recurrence at the site of the vaginal stump was observed when the vaginal length excised was 3 cm. In stage I cases with metastases to the lymph nodes and in stage II cases, no significant difference was discovered between the length of vagina excised in cases with positive and those with negative recurrences of the carcinoma at the site of the vaginal stump.

Endoscopic therapy in patients with inoperable early gastric cancer.

The efficacy and safety of endoscopic therapy was investigated prospectively in 42 patients with 44 early gastric cancers who were not candidates for surgery. Thirty-five of the 44 lesions (80%) were treated by endoscopic therapy alone. Adequate tumor resection was possible in lesions less than 2 cm in diameter, in those of the protruding, flat, and erosive types, and in those located in the antrum. None of the 35 patients who were judged completely cured by the initial therapy developed recurrence or lymph node metastases in the follow-up period (range, 3-114 months; mean, 37 months). Therefore, endoscopic therapy appears effective in the treatment of patients with early gastric cancer when the risks of surgery are too high.
