Serum marker KL-6 antigen has been reported to be a valuable indicator of the disease activity of interstitial pneumonia. It is not clear how sensitive the serum KL-6 antigen level is in reflecting histologic changes in lung tissues. We report here the results of serial measurements of serum KL-6 antigen in a 76-year-old male patient with radiation pneumonia. Serum KL-6 antigen levels were more sensitive than lactate dehydrogenase and procollagen type III N-terminal peptide. The level of serum KL-6 antigen appears to reflect the histologic changes of the lung more sensitively than does C-reactive protein.

We performed clinicopathological studies on early-onset sepsis (5 infants, less than 72 hours of life, EOS) and late-onset sepsis (15 infants, greater than 72 hours, LOS) of very low birth weight, less than 1500 g (VLBW). In EOS, the clinical features mimic the respiratory distress syndrome and hematological changes were not observed. The lungs showed slight interstitial pneumonia with structural immaturity, hyaline membranes, hemorrhage, and minimal infiltration by polymorphonuclear neutrophils (PMNs). The pathogen was group B streptococcus or weakly gram-negative bacilli. In LOS, pneumonia proceeded to sepsis and neutropenia with elevated numbers of circulating immature neutrophils, and increased levels of C-reactive protein were observed at the onset of sepsis. Severe pneumonia with infiltration of numerous PMNs and bacterial colonies and polymicrobial infection by nosocomial pathogens such as Staphylococcus aureus and Pseudomonas aeruginosa were common. The thymus and spleen weights varied but retained normal structure in EOS. The thymus was depleted of lymphocytes, and the spleen was hypertrophic but poorly reactive against infection in LOS. The pathogenesis of EOS is regarded as being more closely correlated with lung immaturity and circulatory disorder in early life, whereas that of LOS is associated with immunological defenses of the host, potency of the pathogens, and terminal multiple organ failure.

Twenty-three patients were included in this prospective study about the safety and efficacy of oral low dose methotrexate (MTX) in the treatment of refractory rheumatoid arthritis. Patients received a mean dosage of 6.6 +/- 1.8 (SD) mg weekly over a mean duration of 16.6 +/- 12.5 months. Patients improved significantly in all clinical parameters of efficacy. There were significant reductions in Lansbury joint scores (p less than 0.001), duration of morning stiffness (p less than 0.001), sedimentation rates (p less than 0.001), C-reactive protein (p less than 0.01), IgG(p less than 0.01), rheumatoid factor (p less than 0.01) and significant increase in grip strength (p less than 0.001), hemoglobin (p less than 0.05) after 17 months of treatment with MTX. Radiographic progression of joint disease were assessed using global scoring method. The mean rate of development of erosions and joint-space narrowing during MTX therapy was significantly less than the rate of radiographic progression before MTX therapy (8.1 +/- 7. 9/year vs. 1.9 +/- 3.8; p less than 0.05). Adverse reactions during MTX therapy included transient transaminase elevation (17.4%). Five patients (21.7%) were withdrawn because of leukopenia (2), interstitial pneumonitis (1), stomatitis (1), skin rash (1). We conclude that low-dose methotrexate is effective for the management of clinical disease activity in patients with refractory rheumatoid arthritis and may be a disease-modifying anti-rheumatic drugs (DMAR-Ds) by roentgenographic criteria.

One hundred and thirty seven rheumatoid arthritis (RA) patients refractory to D-penicillamine and some of them (15%) refractory to other slow active drugs were treated with oral methotrexate (MTX) (10-15 mg weekly). After 12-24 months of treatment, 94 and 74 patients respectively showed a significant improvement as judged by duration of morning stiffness (p less than 0.0001), grip strength (p less than 0.0001), degree of joint swelling (p less than 0.01) and tenderness (p less than 0.0001) compared to pre-treatment values. This clinical improvement was also associated with a decrease of erythrocyte sedimentation rate (p less than 0.001), decrease of C-reactive protein (p less than 0.0001) and with improvement of anaemia (p less than 0.05). No changes were seen in rheumatoid factor titres. Seventy-four of the patients were followed for up to 24 months. Thirty-one of them (23%) had complete remission and 43 (31%) had an excellent response. Adverse drug reaction during MTX therapy included: elevated liver enzymes in 34 patients, mucosal ulcers in 21, nausea and vomiting in 8, diarrhoea in 4, leukopenia in 2, interstitial pneumonitis in one, intestinal bleeding in one and finally septic arthritis in another patient. The majority of these side effects were resolved without sequelae. However, 15 patients (11%) with adverse drug reactions had to discontinue the treatment. Forty-one of our patients who received a cumulative mean dose of MTX of 1550.5 +/- 235.5 mg underwent a percutaneous liver biopsy. Ten patients had normal tissue, 12 had minimal changes, 13 nonspecific changes and 6 patients had mild fibrosis.(ABSTRACT TRUNCATED AT 250 WORDS)

We report three patients with pulmonary disorders associated with myelodysplastic syndromes (MDS). All three patients had symptoms of pyrexia and respiratory discomfort. One patient had pulmonary eosinophilia with bilateral pleural effusion, one had interstitial pneumonia, and one had bilateral pleural effusion caused by systemic vasculitis. Elevated C-reactive protein (CRP) levels, polyclonal hypergammaglobulinemia, and morphological abnormalities in peripheral blood were observed in all three patients. The bone marrow of these patients revealed trilineage dysplasia and eosinophilia. Cytogenetic analysis showed [46,XY,-7,+der(1q;7p)]. Antibiotic treatment was not effective. However, improvement was dramatic after corticosteroid treatment; CRP levels were reduced and the hypergammaglobulinemia was improved. These cases suggest that MDS with [-7,+der(1q;7p)] may be correlated with bone marrow eosinophilia and that an immunologic abnormality may be involved in the pulmonary disorders.

Hepatocyte growth factor/scatter factor (HGF/SF) plays an important role in tissue repair in liver and renal damage. The clinical significance of this growth factor in these diseases has also been reported. The lung is one of the major sources of HGF/SF; because of this, we investigated serum HGF/SF levels in 26 patients with inflammatory lung disease (15 with interstitial pneumonitis [IP], 11 with bacterial pneumonia [BP]) by enzyme-linked immunosorbent assay. As controls, we measured HGF/SF in the serum of 13 stable outpatients with chronic respiratory failure. All patients had no significant liver or renal dysfunction. Serum HGF/SF levels were significantly elevated in patients with IP (1.16 +/- 0.22 ng/ml) or BP (0.96 +/- 0.27 ng/ml) compared with those in the control subjects (0.29 +/- 0.03 ng/ml, both p < 0.01). Serum HGF/SF levels in 14 healthy subjects were also studied, and the results (0.30 +/- 0.02 ng/ml) were not remarkably different from those of the control subjects. There were no significant correlations between serum HGF/SF levels and C-reactive protein and lactate dehydrogenase. Serum HGF/SF levels in the surviving patients rapidly decreased with treatment, but they did not change in the patients who ultimately died. Our results demonstrate the clinical significance of serum HGF/SF level as a useful indicator of prognosis in inflammatory lung disease.

We measured soluble IL-6 receptor (sIL-6R) levels in serum and bronchoalveolar lavage fluids (BALF) from patients with interstitial pneumonia of unknown etiology (IP) (n = 17), sarcoidosis (n = 8) and normal control subjects (n = 10), to investigate its role in pulmonary diseases. Soluble IL-6R was determined by an ELISA. The volume of epithelial lining fluid (ELF) in BALF was estimated using an urea method. We found that levels of sIL-6R in serum, BALF, and ELF from patients with IP or sarcoidosis were significantly higher than those from normal subjects. Furthermore, levels of sIL-6R in BALF or ELF were significantly correlated with those of albumin, indicating that sIL-6R, together with albumin, may enter ELF as a result of the increased permeability caused by pulmonary inflammation. Thus most of the sIL-6R in ELF would be from serum, and relatively small amounts of it might be produced locally. However, sIL-6R levels in ELF, but neither serum nor BALF, were significantly correlated with levels of C-reactive protein in patients with IP. These results suggest that both systemic and local production of sIL-6R are increased, and raised sIL-6R is involved in the modulation of systemic and local inflammatory responses in patients with IP and sarcoidosis.

Of 12 patients who underwent lung resections for lung cancer with idiopathic interstitial pneumonia (IIP), eight patients survived and four patients died due to acute exacerbation of IIP after the operation. The preoperative values for percent forced vital capacity, predicted postoperative percent vital capacity, percent one-second forced expiratory volume index and serum level of C-reactive protein were significantly different between the group of patients who survived and that of having died. Three days after the operation, the percentage of lymphocytes among leukocytes and serum level of lactate dehydrogenase in the two groups were both significantly different. These findings showed that the operative strategy for patients with lung cancer and IIP needs specifically careful consideration for operative procedure, and preoperative serum levels of C-reactive protein and postoperative lactate dehydrogenase and the percentage of lymphocytes in leukocytes would be useful in evaluation of the severity of IIP.

Serum levels of interleukin 6 (IL-6) and C-reactive protein (CRP) were measured every second day from day -6 to day +86 in 24 patients undergoing allogeneic (n = 23) and syngeneic (n = 1) bone marrow transplantation (BMT). Endogenous serum levels of IL-6, IL-8, and CRP were further analyzed during complications after BMT, such as fever of unknown origin (FUO), severe infectious complications and acute graft-versus-host disease (GVHD). In addition, CRP levels were measured in 10 patients with interstitial pneumonitis of various origins (CMV, idiopathic). In all 24 patients IL-6 and CRP levels showed a characteristic monophasic pattern. After a slight decrease in the first days after BMT, a significant increase was observed, starting on day +3/+5 (P < 0.05) and reaching peak levels on day +9/+11 (P < 0.01). CRP had a similar pattern, with an increase in serum levels on day +3/+5 and maximum levels one to three days after the IL-6 peak was reached. The magnitude of the peak was related to the development of complications in the further course of BMT and was high in patients with and low in patients without complications. Serum levels of both molecules returned to baseline after day 14 posttransplant. Increased IL-6 and CRP levels were observed in the further course of BMT during severe infections or FUO either on the day of clinical onset (IL-6) or three days later (CRP), but not during acute GVHD grade III/IV. CMV interstitial pneumonitis (CMV-IP) was accompanied by an increase in CRP levels, while no such elevations were observed in patients with idiopathic interstitial pneumonitis (IIP). Elevated IL-8 serum levels occurred during bacterial infections, but to a lesser amount also during GVHD and CMV-IP. In conclusion, a characteristic pattern of IL-6 and CRP was observed after allogeneic BMT and a further increase associated with infectious complications. Since no significant elevations were seen in patients with GVHD, we conclude that both molecules are not involved in the induction of GVHD and might be useful diagnostic tools for the prediction and diagnosis of infectious complications after BMT. In contrast, assessment of IL-8 serum values does not permit clinical complications to be specified.

Sixty-one children were treated in hospital from 1981 to 1982 because of both radiologically and microbiologically verified viral or bacterial pneumonia. The chest radiographs were interpreted by two radiologists, not familiar with the clinical data, on two occasions three years apart, and only those patients with a definite alveolar (n = 27) or interstitial (n = 34) pneumonia at both evaluations were included in the present analysis. In addition, all patients had viral (n = 20), mixed viral-bacterial (n = 21) or bacterial (n = 20) infections diagnosed by viral or bacterial antibody or antigen assays. Viral infection alone was seen in 7 (26%), mixed viral-bacterial infection in 8 (30%) and bacterial infection alone in 12 (44%) of the 27 patients with alveolar pneumonia. The respective figures were 13 (38%), 13 (38%) and 8 (24%) for the 34 patients with interstitial pneumonia. C-reactive protein concentration was greater than 40 mg/l (a screening limit for viral and bacterial infections) in 15 (56%) of the patients with alveolar and in 11 (32%) of the patients with interstitial pneumonia. Thus 74% of the patients with alveolar and 62% with interstitial pneumonia had bacterial infection, either alone or as a mixed viral-bacterial infection. Our results suggest that the presence of an alveolar infiltrate in a chest radiograph is a specific but insensitive indicator of bacterial pneumonia. We conclude that patients with alveolar pneumonia should be treated with antibiotics. In patients with interstitial pneumonia, however, both viral and bacterial aetiology are possible. In those, the decision concerning antibiotic treatment should be based on clinical and laboratory findings.
