Fifteen women with pseudo-LE syndrome were studied. The dissease is characterized by recurrent attacks of fever, myalgia, arthralgia, visceral manifestations (pericarditis, myocarditis, pleurisy, pleural effusion and lung involvement). A prominent feature was an abnormal liver function with elevated GOT and GPT levels in serum, and impaired bromsuophalein elimination. The incidence of varicosities and thrombophlebitis was markedly increased. There was a correlation between complement-fixing antimitochondrial antibody (AMA) titres and the degree of activity of the disease. A reverse correlation was observed between antimitochondrial antibody titres and the absolute lymphocyte count in peripheral blood. In all instances the antimitochondrial antibodies were of polyclonal origin, belonging mainly to immunoglobulin class IgG and, in a few patients, IgM, IgA, or IgD. AMA titres, lymphocyte counts in peripheral blood, sedimentation rate, serum iron level and alpha1- and alpha2-globulins proved to be valuable in following the course of the disease. Other values (C-reactive protein, alpha1-acid glycoprotein, immunoglobulin and beta1c-globulin in serum) were not helpful.

Serum hepatocyte growth factor levels were measured in hepatectomized and nonhepatectomized surgical patients. The levels were significantly increased and reached a maximum within 7 days after surgery in both groups, returning to preoperative levels 28 days after partial hepatectomy and 7 days after other operations. Multiple regression analysis showed that such maximal hepatocyte growth factor levels were significantly related to having liver cirrhosis and postoperative maximal serum total bilirubin and alanine aminotransferase levels and peripheral white blood cell counts in the hepatectomized group and to postoperative maximal peripheral white blood cell counts and serum C-reactive protein levels in the nonhepatectomized group. However, the levels showed no relation to the resected liver volume and increment of the remaining liver volume 28 days after partial hepatectomy. It is concluded that serum hepatocyte growth factor levels were increased after partial hepatectomy in association with hepatocellular dysfunction and necrosis and systemic inflammation. It is unlikely that the increase was related to liver regeneration.

A 67-year-old Japanese housewife, who had been attended the out patient department of medicine, Fukuoka Dental College (FDC) Hospital for paroxysmal atrial fibrillation, was admitted to FDC Hospital because of high fever, exhaustion, anorexia, myalgia and mild stupor. Her ECG finding revealed atrial fibrillation and roentgenologic examination of the chest showed diffuse opacities in the left lung field (S10) without pleural effusion. As she had told her physician that her pet parakeet had been dead recently, she was diagnosed immediately as psittacosis. She was instantly treated with minocycline orally and deslanoside intravenously. Laboratory findings on admission disclosed the following results: Complement-fixing antibodies against Chlamydia psittaci were 1:64, and liver dysfunction (GOT 253, GPT 86, LDH 846) was shown. The white blood cell count was 4,700 associated with shift to the left, C-reactive protein was 6 plus and the erythrocyte sedimentation rate was 109 mm in 1 hour. The course in the hospital was satisfactory and after 38 hospital days she was discharged with complete recovery from the psittacosis. It is emphasized the importance of that the question about the history of contact with psittacine birds or other avian species is essential to diagnose psittacosis.

The systemic administration of interleukin-2 (IL-2) can lead to significant antitumor responses in some patients with metastatic cancer in whom standard therapy has failed. A limitation of this immunotherapy is the toxicity associated with IL-2 infusion. To assess toxicity, we determined aspartate aminotransferase (AST; EC 2.6.1.1), alanine aminotransferase (ALT; EC 2.6.1.2), gamma-glutamyltransferase (GGT; EC 2.3.2.2), lactate dehydrogenase (LD; EC 1.1.1.27), alkaline phosphatase (ALP; EC 3.1.3.1), creatine kinase (CK; EC 2.7.3.2), total bilirubin (TBI), direct bilirubin (DBI), creatinine, urea nitrogen, and C-reactive protein in serum from 21 patients before and during five consecutive days of IL-2 treatment. Ten patients were followed for an additional five days after the end of IL-2 therapy. The IL-2 infusion caused liver toxicity and prerenal azotemia, as evidenced by significant increases (P less than 0.05) of all analytes except CK by day 1. There was a progressive increase in the results (except CK) for these tests until IL-2 treatment was stopped. Seven tests related to liver function (AST, ALT, GGT, LD, ALP, DBI, and TBI) showed increases, but the test results indicated significant improvement and moved toward the baseline value five days after the end of IL-2 therapy. Concentrations of creatinine and urea nitrogen in serum were normal three days after the cessation of IL-2 therapy.

Endotoxin stimulates production of both C-reactive protein (CRP) and cortisol in the plaice within 24 hr. Cortisol alone (optimum dose i.p. 500 micrograms/300 g wt fish) also stimulates CRP production and the possibility that endotoxin acts through cortisol was examined. Dexamethasone suppresses cortisol production but elevates CRP. Cortisol levels are restored to normal within 24 hr of endotoxin injection. Turpentine and ACTH which stimulate cortisol do not affect CRP. Endotoxin and cortisol have no significant effect on alanine aminotransferase activity in the serum and liver although it is elevated in the serum within 24 hr of the administration of adrenalin or turpentine.

C-reactive protein (CRP) is a liver-specific acute-phase protein, and its expression in hepatocyte is regulated by cytokines such as interleukin-1, interleukin-6 and tumor necrosis factor-alpha. Although several alterations in cytokines have been found in patients with chronic viral hepatitis, it remains obscure how CRP expression is associated with progression of the disease in chronic viral infection. In the present study, CRP expression was evaluated in 45 patients with chronic hepatitis B and in 38 patients with chronic hepatitis C. By the immunohistochemical analysis, the intensity of CRP expression in hepatocyte was closely associated with the histology activity index (HAI) score in chronic hepatitis B. In contrast, the association was not found in chronic hepatitis C. When serial changes in serum levels of CRP were compared in long-term follow-up patients including 5 patients with chronic hepatitis B and 4 patients with chronic hepatitis C, serum levels of CRP fluctuated simultaneously with serum levels of alanine aminotransferase in chronic hepatitis B, whereas the correlation was not recognized in chronic hepatitis C. These results suggest that CRP expression correlates with progression of the disease in chronic hepatitis B, but not in chronic hepatitis C. It is also possible that cytokine-mediated response is more pronounced in chronic hepatitis B than in chronic hepatitis C.

Giant aneurysms are the most serious issue of patients with Kawasaki disease (KD). To clarify risk factors for these giant aneurysms, we conducted a matched case-control study. Among the patients reported in nationwide surveys, 117 patients with giant aneurysms had an unequivocal new diagnosis and presented at the treatment center within 9 d of illness. We obtained clinical information on admission of about 69 patients (case) from the treatment centers. One control was selected for each case, an age- and sex-matched patient without coronary involvement, reported from the same treatment center at about the same time as the case, and we obtained the same clinical information about controls. Fourteen variables were analysed with a conditional logistic regression model: body temperature, hematocrit, hemoglobin, numbers of leukocyte and platelets, concentrations of serum albumin, globulin, total cholesterol, sodium, potassium and chloride, erythrocyte sedimentation rate, C-reactive protein and alanine aminotransferase activity. After adjustment for age, duration of illness before admission and use of intravenous gamma globulin therapy, C-reactive protein [odds ratio (OR)=1.142, 95% confidence interval (CI) 1.054-1.237], alanine aminotransferase activity (OR=1.008, 95% CI 1.002-1.014), serum sodium concentration (OR=0.877, 95% CI 0.770-0.999) and serum potassium concentration (OR=0.319, 95% CI 0.124-0.822) were significantly related to the risk for giant aneurysms. Further analyses with these four explanatory variables revealed that C-reactive protein (OR=1.159, 95% CI 1.022-1.315) and serum potassium concentration (OR=0.222, 95% CI 0.052-0.948) met the significant level. Thus, the values for serum C-reactive protein and potassium are independent risk factors for the development of the giant aneurysms of Kawasaki disease.

We recently showed that heparin-binding EGF-like growth factor (HB-EGF) has hepatotrophic effects. In this study, we developed an ELISA system with high specificity and sensitivity for human plasma HB-EGF. In 14 patients who underwent partial hepatectomy, plasma HB-EGF levels were measured serially after surgery. In patients who underwent gross hepatectomy (lobectomy and segmentectomy), plasma HB-EGF levels increased, reaching maximal levels approximately 5 to 7 days after surgery. In patients who underwent minor hepatectomy (subsegmentectomy), plasma HB-EGF levels did not increase. Maximal plasma HB-EGF levels were significantly higher in patients who had a percent increased volume of the remaining liver (%ILV) above 20% than those who had a %ILV below 20% (32.4 +/- 19.6 pg/ml vs 7.4 +/- 2.7, P < 0.05). The plasma HB-EGF values did not correlate with WBC counts, C-reactive protein, or alanine aminotransferase. Plasma HB-EGF may be a marker for liver regeneration after hepatectomy in humans.

A pilot dose-escalation study of recombinant human interleukin 12 (rhIL-12) was conducted in Japanese patients with advanced malignancies. Cohorts of three patients received escalating doses of rhIL-12 that increased from 50 to 300 ng/kg/day s.c. three times a week for 2 weeks followed by 1-week rest. The same dosage and schedule was repeated for two additional courses. Sixteen previously treated patients were registered, and 15 were evaluated. Common toxicities were fever and leukopenia; the abnormality of laboratory tests included elevations in aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, C-reactive protein, and beta2-microglobin. Dose-limiting toxicity was the grade 3 elevation of aminotransferases, and was observed in two of six patients at the 300-ng/kg dose level after the first course in one patient and after the third course in the other. Leukopenia was observed at all of the dose levels; two of six patients at 300 ng/kg experienced grade 3 leukopenia. Thus, 300 ng/kg was determined to be the maximum acceptable dose. Peak plasma levels of rhIL-12 decreased in the second courses, but the areas under the curve were almost the same in the first and second courses. Biological effects included increases of plasma levels of IFN-gamma, tumor necrosis factor-alpha, IL-6, IL-10, and neopterin. In two patients with renal cell carcinoma, complete response and partial response of metastatic tumors were observed with 50 and 300 ng/kg; the responses lasted for 5 and 3.5 months, respectively. Although immunological response to rhIL-12 varies depending on administration route and schedule and on patients' physiological conditions, the recommended dose for Phase II studies is 300 ng/kg s.c. three times a week for 2 weeks followed by 1-week rest.

Serum creatine kinase (CK) activity is reduced in some conditions, including rheumatic diseases, but the aetiology and significance remain to be clarified. The aim of this study was to investigate relationships between serum CK activity and other muscle enzymes, muscle mass, renal function, steroid use and disease activity in patients with rheumatic diseases. Serum CK activity was measured in sera from 498 patients with rheumatic diseases: rheumatoid arthritis (RA, n = 145), systemic lupus erythematosus (SLE, n = 31), spondyloarthropathies (SpA, n = 35), polyarthralgia/arthritis (Poly, n = 74), miscellaneous group (MI, n = 46), and in non-inflammatory arthropathies (NIA, n = 167) as controls. Serum CK level was significantly reduced in RA (45.4 +/- 1.9 IU/l), SLE (46.4 +/- 4.2 IU/l), SpA (64.7 +/- 5.6 IU/l) and MI (63.4 +/- 4.8 IU/l), but not in poly (70.2 +/- 3.1 IU/l), compared to controls (78.9 +/- 2.4 IU/l) (P < 0.05). CK values correlated with aspartate aminotransferase (AST), erythrocyte sedimentation rate (ESR), body mass index (BMI) and platelets (Plat) in RA; ESR and haemoglobin (Hb) in SLE, AST, ESR and Hb in SpA; lactate dehydrogenase (LDH), AST, ESR and Hb in Poly; LDH, AST, ESR, Hb and Ccr in MI; and LDH, AST and ESR in controls. In all patients with rheumatic diseases CK level was significantly correlated with LDH, AST, alanine aminotransferase (ALT), ESR, C-reactive protein (CRP) and BMI and prednisolone dose, but not with Ccr, age and disease duration. In conclusion, our data support the possibility that reduced CK activity is inversely correlated with inflammatory activity and correlated with other muscle enzymes, muscle mass and steroid use, but not with renal function, age and disease duration in rheumatic diseases.
