A case of auranofin(AF)-induced acute interstitial pneumonitis in a patient with rheumatoid arthritis (RA) is reported and possible mechanism of the incidence is discussed. A 57 year-old woman with a history of RA starting in early April 1989, had been prescribed AF for seven days prior to her referral to this hospital. Because of the severity of her polyarthritis, AF was discontinued; therapy with gold sodium thiomalate (GST) instead was started on 23 June 1989. The patient responded quite favorably. At a total cumulative dose of 160mg of GST, however, she developed generalized exfoliative dermatitis and the drug was discontinued. On 29 Sept. 1989 when her skin lesions cleared up completely, she was put on AF again. Six days after resumption of AF therapy, she developed fever. Nonproductive cough and dyspnea on exertion was observed within the following three days. The chest X-ray film revealed diffuse reticular-linear infiltrates more prominently in both upper lobes. Arterial blood gas studies showed hypoxemia and a restrictive ventilatory defect was demonstrated by pulmonary function studies. AF was stopped. High dose pulse iv corticosteroid(CS) therapy combined with oral CS was instituted. Immediate improvement of both subjective and objective findings was observed. By using the patient's peripheral blood lymphocytes, delayed lymphocyte stimulation test(DLST) against the probable causative agents was performed before the bolus CS therapy. Stimulation Index(shown in percentage) was markedly elevated in AF(724%) as compared with GST(163%). The fiberoptic bronchoscopy with bronchoalveolar lavage(BAL) was performed. Analysis of BAL fluid revealed increased cellularity (9 x 10(5)/ml) with marked lymphocytosis of 79%.(ABSTRACT TRUNCATED AT 250 WORDS)

Tumor-associated carbohydrate antigens, CA19-9 and SLEX have been used clinically as markers for malignancy. However, it is also known that these antigens are frequently elevated in the serum of patients with benign lung diseases. We have experienced two cases of interstitial pneumonitis with marked increase of carbohydrate antigens in serum, the level of which changed according to their clinical course. Case 1. A 64-year-old woman was admitted because of a cough and exertional dyspnea. Despite treatment with various antibiotics and prednisolone, she died of respiratory failure approximately two months after admission. Her CA19-9 and SLEX in serum elevated from 500 U/ml to 5506 U/ml and 167 U/ml to 1187 U/ml respectively in accordance with clinical deterioration. Autopsy revealed no malignancy. Case 2. A 57-year-old woman, who had been suffering from interstitial pneumonitis associated with rheumatoid arthritis, was admitted with a cough and fever. She responded to prednisolone therapy, however two years later she readmitted because of exacerbation and died of respiratory failure. The initial CA19-9 level in serum was 876 U/ml and dropped to 42 U/ml with prednisolone therapy. The serum antigen level again increased during the period of exacerbation, and showed 133 U/ml immediately before death. An immunohistochemical study of CA19-9 and SLEX in various tissues obtained by autopsy was performed in case 1. The distribution of these antigens in tissue was similar to that of normal individuals. The exceptions were the expression of these antigens on epithelial cells of microscopic honeycombing and on mucinous exudates in air spaces.

Two cases of hypersensitivity pneumonitis due to contamination of ultrasonic-humidifier were reported. The first case, a 64-year-old man, developed fever and dyspnea on exertion in January 1986. He was hospitalized for 18 days and received antibiotics for presumptive bacterial pneumonia. Half a day after discharge, those symptoms recurred. On readmission, fine crackles were heard at the left lung base, and chest X-ray film showed ground glass shadows all over the lung fields. Bronchoalveolar lavage (BAL) and transbronchial lung biopsy (TBLB) were performed on the next day after readmission. TBLB specimen revealed lymphocyte alveolitis, granulomatous tissue and infiltration of polymorphonuclear neutrophils (PMN) in alveoli. Differential cell count of the BAL fluid showed not only lymphocytosis (38.2%) but also increased PMNs (44.2%). In the second BAL performed 18 days later, the value of PMNs demonstrated a dramatic decrease. Environmental challenge tests revealed that his hypersensitivity pneumonitis was caused by an ultrasonic humidifier in his bed room. Immunological examinations showed positive Arthus type skin reaction and serum precipitin against Aspergillus fumigatus. Inhalation challenge with A. fumigatus produced cough and dyspnea with a decrease of 10 Torr in PaO2. These data suggest that A. fumigatus may be the causative antigen in this case. The second case, a 64-year-old man who had used ultrasonic humidifier in his living room, was admitted for 8 weeks with an illness characterized by cough, low fever and general malaise on 22 January 1987. Examination revealed fine crackles on both lung bases. Chest X-ray film demonstrated diffuse nodular shadows. The TBLB specimen showed lymphocytic alveolitis and bronchiolitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Measuring peak expiratory flow rates (PEFR) several times a day can provide an objective assessment of functional changes relative to environmental or occupational exposures. This report describes the pattern of diurnal changes in PEFR in a reference population, and defines ranges of "normal" between- and within-day variability. An index of diurnal changes was defined as the ratio between maximal and minimal values, where the maximal value was restricted to PEFR measured at noon or in the evening (N, E) and the minimal value was restricted to the morning or at bedtime (M, B). A ratio greater than normal represented an exaggeration of the normal diurnal pattern in PEFR. Normal limits, based on the ninety-fifth percentile in the reference population, were larger for children (130%) than for adults 15 to 35 yr of age (117%) and those older than 35 yr of age (118%). The meaningfulness of excessive diurnal changes in PEFR was examined by relating this ratio (Max/Min), and a similar measure (the amplitude percent mean) to chronic respiratory symptoms and diseases in 938 adults and children who recorded PEFR values 2 to 4 times per day for as long as 14 days. There was a strong relationship of diurnal changes in PEFR that exceed normal limits with physician-confirmed asthma (relative risk of 2.99 with Max/Min), with exertional dyspnea (Grade 2+), and with more frequent reporting of acute symptoms of wheeze, attacks of wheezing dyspnea, cough, and chest colds. In addition, those exceeding the normal limits had about 2.9 times greater risk of having a FEV1 below 80% of predicted, and nearly 7 times greater risk of being below 70%.(ABSTRACT TRUNCATED AT 250 WORDS)

We assessed the effects of occupational exposure in a general population sample living in an unpolluted rural area of North Italy. In the age range of 18 to 64 yr, there were 417 participants who reported any exposure to dusts, chemicals, or gases and 1,218 who reported no exposure. Each subject completed a standardized interviewer-administered questionnaire (CNR-questionnaire). A variable proportion of participants succeeded in performing flow-volume curves, diffusing capacity of carbon monoxide, and slope of alveolar plateau of nitrogen. There was no significant difference for symptom prevalence rates between exposed and nonexposed in men and women who smoke. In nonsmoking women, those exposed showed significantly higher prevalence rates for exertional dyspnea and asthma. Regarding lung function, in exposed male smokers there was a significantly higher slope of the alveolar plateau. In exposed female nonsmokers, FEV1 and forced expiratory flows were significantly lower. Multiple logistic models in the overall group, accounting for age, smoking, and pack-years, showed that work exposure was associated significantly with higher risks for all symptoms in men (e.g., odds ratio: 2.76 for dyspnea, 2.31 for asthma, 1.69 for cough, and 1.64 for phlegm); in females, the association was significant for dyspnea (OR = 3.74) and asthma (OR = 3.29). Exposed men also had a significantly higher risk for %FEV1 or FEV1/FVC% below 70 (OR = 1.45). Our findings confirm those of the other few epidemiologic surveys in general population samples and contribute to the suggestion of a causal association between occupational exposure and chronic obstructive pulmonary disease.

The clinical, radiological, physiological and pathological features were studied in 6 cases of idiopathic bronchiolitis obliterans organized pneumonia (BOOP). Patients characteristically had a history of exertional dyspnea, cough, fever, weight loss, bilateral radiographic shadowing, elevated ESR and hypoxemia. Corticosteroids were effective; however, one patient died of cytomegalovirus pneumonia. The pathological features, distinguished by the presence of granulation tissue plugs extending from bronchioles into alveolar ducts and alveoli, are described in detail. The place of BOOP within the broad spectrum of bronchiolitis obliterans between small airways disease and usual interstitial pneumonia is discussed.

Tracheobronchopathia osteochondroplastica is an unusual disease of obscure causation characterized by cartilaginous or bony outgrowths into the lumen of the tracheobronchial tree. Our retrospective review of 15 patients, 8 of whom were women, revealed a mean age of 63.5 years. The most common symptoms were cough (66%), hemoptysis (60%), dyspnea on exertion (53%), and wheeze (30%). Thirteen percent of the patients were asymptomatic. Chest radiography was not helpful in the diagnosis. Tracheal tomography revealed typical beaded intraluminal calcification in 4 of the 12 patients tested. Mirror laryngoscopy initially revealed the abnormalities in 30% of the patients, and bronchoscopy confirmed the diagnosis and determined the extent of the disease in all patients. Even though upper airway involvement has been thought to be uncommon, 40% of our patients demonstrated abnormalities of the larynx and upper trachea. Histologic confirmation of heterotopic bone formation was obtained in 60% of the patients. Pulmonary function tests showed mild obstructive lung disease. There were no deaths directly attributable to the disease. Treatments attempted included cryotherapy, laser excision, external beam irradiation, and bronchoscopic removal of the obstructing lesions.

The use of radiation therapy is limited by the occurrence of the potentially fatal clinical syndromes of radiation pneumonitis and fibrosis. Radiation pneumonitis usually becomes clinically apparent from 2 to 6 months after completion of radiation therapy. It is characterized by fever, cough, dyspnea, and alveolar infiltrates on chest roentgenogram and may be difficult to differentiate from infection or recurrent malignancy. The pathogenesis is uncertain, but appears to involve both direct lung tissue toxicity and an inflammatory response. The syndrome may resolve spontaneously or may progress to respiratory failure. Corticosteroids may be effective therapy if started early in the course of the disease. The time course for the development of radiation fibrosis is later than that for radiation pneumonitis. It is usually present by 1 year following irradiation, but may not become clinically apparent until 2 years after radiation therapy. It is characterized by the insidious onset of dyspnea on exertion. It most often is mild, but can progress to chronic respiratory failure. There is no known successful treatment for this condition.

A 49 year-old Japanese female with a clinical history of rheumatoid arthritis for 15 years developed fever, cough, sputa and exertional dyspnea. A chest x-ray showed right-sided pleural lesions in addition to persistent hyperinflation of the lungs for about four years. Pulmonary function tests showed combined obstructive and restrictive dysfunction, increased residual volume and reduced diffusing capacity. After an improvement of the pleural lesions, she underwent a right open lung biopsy in December 1988 which revealed follicular bronchiolitis and fibrino-fibrous pleural thickening. The pulmonary lesion of follicular bronchitis/bronchiolitis was reported in 1985 as a newly recognized pulmonary disorder among open lung biopsy cases. The present case was the second biopsy proven case of follicular bronchiolitis among the Japanese.

The pulmonary changes of progressive systemic sclerosis in 8 cases were reported. The major clinical complaints were unproductive cough and exertional dyspnea. Pulmonary function tests showed restrictive ventilatory defects and impaired diffusing capacity in most of the cases examined. On chest X-rays, diffuse mottling and linear densities were seen in lungs, predominately in the basal regions. On pathological examinations, pulmonary interstitial fibrosis occurred in early stage of the disease. The results showed that pulmonary involvement may be an early event in progressive systemic sclerosis.
