A new human extrahepatic bile duct carcinoma cell line (KMBC) was established from a serially transplanted tumor in nude mice that originated from a surgically resected tumor from a 73-year-old Japanese man; the cell line has been maintained for 5 five years. KMBC cells proliferate in a monolayered sheet with a population doubling time of 30 hours. Chromosome number was distributed in a range from 37 to 44, with modal numbers of 40 and 41. KMBC cells and the reconstituted tumor in a nude mouse showed moderately to poorly differentiated adenocarcinoma and possessed various functional characteristics of extrahepatic bile duct carcinoma. KMBC cells secreted carbohydrate antigen 19-9, tissue polypeptide antigen, carcinoembryonic antigen, ferritin, beta 2-microglobulin, fibronectin, and alpha 2-macroglobulin and produced glutamic oxaloacetic transaminase and alkaline phosphatase. KMBC is the second established cell line that originated from a human extrahepatic bile duct carcinoma in the world literature, and it will be applicable to various experiments.

Efficacy of blood UV irradiation (BUVI) followed by its reinfusion to the patient in combination with antibacterial therapy was studied in patients with acute and chronic pyelonephritis and its purulent septic complications. The BUVI was used when the antibacterial drugs failed to be sufficiently efficient and the clinical process of the infection was severe. The kinetics of ferritin, transferrin, alpha 2-macroglobulin, beta 2-microglobulin and haptoglobulin in the blood serum was investigated as a criterion of treatment efficacy. It was shown that the BUVI markedly increased the chemotherapy efficacy. The observed regularities of the changes in the serum antigenic spectrum can be used as a basis for the control of treatment efficacy.

The levels of tumor markers were determined in 173 patients with rectal cancer recurrences by radioimmunoassay. An increase in a CEA level was observed most frequently (92.5%). An increase in the levels of alpha-fetoprotein, ferritin and beta 2-microglobulin was observed in 61.7, 56.6 and 46.3%, respectively. CA-19-9, a carbohydrate antigen, was of no importance for the detection of cancer of this site, and an increase in its titer was observed in 15.5% only. Thus the most specific and effective diagnostic test for the diagnosis of rectal cancer recurrences is the determination of a CEA level.

Using radioimmunological estimation of beta 2-microglobulin (beta 2M), significantly greater serum values were found in 36 dialysis patients (44.4 +/- 20.3 mg/l) in comparison to healthy probands (1.5 +/- 0.2 mg/l). A significant relation to the duration of dialysis, diuresis and serum aluminium and ferritin was found. The used dialysers MLW 1.3/1.8 m2 (regenerated cellulose membrane) did not eliminate beta 2M from the blood. Significantly greater beta 2M concentrations were observed in patients suffering from arthralgia and bone pain, but not in radiologically verified arthropathy and destructive spondylarthropathy. Post-mortem examinations of 13 patients on haemodialysis treatment for between 10 and 90 months revealed synovial beta 2M-derived (AB-)amyloid deposits in four patients at different joints, but not in radiologically suspect areas. The results suggest that independent of serum beta 2M, beta 2M-derived amyloidosis may occur in elderly patients on dialysis for less than 5 years. Several cases were completely asymptomatic.

We have investigated the importance of several clinical and laboratory parameters on the development of acquired cystic kidney disease (ACKD) as detected by ultrasonography in 19 patients who had received dialysis therapy for at least three years. We were particularly interested on the possible effect of the serum levels of oxalate and silicon, which can produce tubular obstruction, and that of vanadium, which can affect cell proliferation. The severity of ACKD increased with the duration of dialysis and was greater in men than in women. Positive correlations were observed between the grades of ACKD and the levels of hemoglobin, hematocrit, and parathyroid hormone, while there was a negative correlation between ACKD and serum ferritin levels. The serum levels of oxalate, silicon, and vanadium, pre- and postdialysis, were markedly and significantly higher than those in normal controls, but there was no significant correlation between these levels and the duration of dialysis therapy or severity of ACKD. The pre- and postdialysis levels of vanadium were not significantly different, while the levels of oxalate and silicon were significantly lower in the postdialysis samples. No significant correlations were detected between ACKD and age of the patients, blood pressure, protein catabolic rate, efficiency of dialysis index, or the serum levels of iron, sodium, potassium, calcium, phosphorus, aluminum, and beta 2-microglobulin.

At present, no sufficient therapy for metastatic renal cell carcinoma is available. Several immunotherapeutical protocols have been studied, success rates, however, were inconsistent. The purpose of this study was to assess the pretherapeutic immunological status of 13 patients with metastatic and 16 patients with nonmetastatic renal cell carcinoma and of 15 healthy volunteers. Determined were differential blood counts, lymphocyte subpopulations, beta 2-microglobulin, tumor necrosis factor (TNF), neopterin, immunoglobulin, fibronectin and ferritin. Additionally, these parameters were recorded for monitoring an immunotherapeutical approach with the xenogeneic biological response modifier Keyhole limpet hemocyanine (KLH) in 10 patients with metastatic and in 5 patients with nonmetastatic disease. The pretherapeutic immunological status of patients with metastatic disease was characterized by significantly reduced T4-, T8- and B-cell counts. Significantly increased were granulocyte counts, beta 2-microglobulin, neopterin and TNF. In patients who did not suffer from metastases, only beta 2-microglobulin and neopterin were increased significantly. During immunotherapy, in patients with metastases, there was a decline of lymphocyte subsets and of the T4/T8-ratio, which correlated with progress of the disease. Humoral immune parameters showed no changes compared to pretherapeutic values. In patients who did not suffer from metastases, cellular immune parameters showed stable values during immunotherapy; neopterin, beta 2-microglobulin and TNF increased considerably. These findings indicate immunosuppression in patients with metastatic renal cell carcinoma, increasing with progression of the disease and possibly impairing the immunostimulating effects of biological response modifiers during immunotherapy. In conclusion, the clinical response of metastatic renal cell carcinoma to immunotherapy might be improved if the immunostimulant is combined with agents suitable to overcome immunosuppression, i.e. low doses of cyclophosphamide or inhibitors of prostaglandin synthesis. In addition, assessment of immune parameters for monitoring the actual immune status of a patient and the immunological effects of therapy was found to be a necessary part of immunotherapy.

In order to clarify possible factors responsible for varying responses in uremic patients treated with recombinant human erythropoietin (rHuEPO), we determined the inhibitory effects of ten uremic sera on the erythroid progenitors (CFU-E) and erythroid bursts (BFU-E). We also measured plasma EPO titers, Fe, UIBC, ferritin, PTH-C, beta 2-microglobulin, and aluminum in all ten patients. The inhibitor of CFU-E but not BFU-E, was present in the serum of the single anemic patient whose recovery took longer after the administration of rHuEPO. He did not have such conditions as iron deficiency, excess of aluminum, or chronic inflammation. The remaining patients, who had no CFU-E or BFU-E inhibitors, were good responders to rHuEPO. In none of ten patients were there inhibitors of granulocyte-macrophage progenitors (CFU-GM) or any differences in the other parameters. Although the inhibitory factor of CFU-E can be overcome with a larger dose, its prior determination may be useful to set out minimal effective dose of EPO treatment.

Out of a population of 97 haemodialysis patients, 36 patients with dialysis arthropathy were identified. Dialysis arthropathy is a chronic symmetrical polyarthritis which affected 97 per cent of the patients who had been undergoing cuprophane haemodialysis for more than 10 years. It commonly affected the shoulders, hips, hands, knees and wrists, worsening with time and extending to other joints. Fifty-eight per cent of the patients complained of morning stiffness and 47 per cent complained of exacerbation of shoulder pain during or after haemodialysis. Half of the patients also suffered from carpal tunnel syndrome, which recurred and was associated with a long-lasting disability. The most common radiological abnormality was periarticular bone cysts, followed by articular erosions and a destructive spondyloarthropathy, but clinical symptoms were more common than radiological signs. Patients with dialysis arthropathy had a higher C-reactive protein level than patients without arthropathy (18.6 mg/l versus 11.4 mg/l), indicative of an inflammatory process. Some of the clinical manifestations of the disease correlated with levels of C-reactive protein and ferritin. Serum ferritin levels correlated strongly with the units of blood transfused in the past five years (RS = 0.83), and the logarithm of ferritin level correlated weakly with C-reactive protein (r = 0.32). Haemarthroses were documented in 19 per cent of patients. Mean serum beta 2-microglobulin was elevated in the patients with (57.3 mg/l) and without arthropathy (50.7 mg/l), and there was no difference in the parathormone or aluminium levels between these groups. Articular tissue was obtained in 25 patients; beta 2-microglobulin amyloid was present in 24. Larger deposits were present in the capsular tissue, and these appeared to replace collagen bundles in eight cases. Amyloid deposits replaced the lining layer in six cases. It is likely therefore that amyloid disrupts normal joint function by replacing normal joint tissue. Mild chronic synovitis with haemosiderin deposition were found in approximately 60 per cent of cases. These findings suggest that amyloid derived from beta 2-microglobulin has a primary role in the pathogenesis of dialysis arthropathy, but there was also evidence of inflammatory processes. It is suggested that iron overload or haemarthroses might contribute to the inflammation, but other factors, such as dialysis-related bioincompatibility reactions, may also have a role.

Using Prolifigen TK kit "Daiichi", the serum TK level were determined in patients with adult T-cell leukemia (ATL) and its related disorders. The mean level of serum TK at diagnosis was 279.9 U/l in acute type ATL, 27.8 U/l in chronic type ATL, 59.0 U/l in lymphoma type ATL, 3.1 U/l in pre-ATL and 2.4 U/l in HTLV-I carriers. In these patients, six other kinds of tumor markers such as lactic dehydrogenase, beta 2-microglobulin, immunosuppressive acidic protein, ferritin, tissue polypeptide antigen and carcinoembryonic antigen were also examined. Among the seven tumor markers, TK level showed the most significant difference among clinical subtypes of ATL. This indicates that the TK level is one of the promising parameters indicative of aggressiveness of ATL cells.

Sera from 171 patients with advanced lung cancer, from 110 normals, and from 123 subjects with benign respiratory diseases were analyzed for 10 substances to detect lung cancer: ferritin, lipid-bound sialic acid, total sialic acid, beta 2-microglobulin, lipotropin, the alpha and beta subunits of human chorionic gonadotropin, calcitonin (two assays), parathyroid hormone, and carcinoembryonic antigen. Individual markers were studied, and optimal combinations of markers were sought for discriminating lung cancer patients from normals and from patients with benign lung disease. Numerous methods for combining the markers were examined, but the methods of logistic regression and recursive partitioning were finally adopted. The best discrimination rules we could find used only carcinoembryonic antigen (CEA) and total sialic acid (TSA). The performance of these rules was validated on an independent serum panel containing sera from 68 patients with advanced lung cancer, from 40 normals, and from 52 patients with benign respiratory disease. The combination rules based on TSA and CEA performed better than a rule based on CEA alone. Logistic discrimination rules with TSA and CEA that were designed to have 95% specificity achieved 54% sensitivity for discriminating advanced lung cancer from normal controls and 52% sensitivity for discriminating advanced lung cancer from controls with benign disease. Some aspects of clinical applicability are discussed, including planned studies for localized lung cancer and the requirement for further testing in specific clinical settings.
