1/97. mycoplasma pneumoniae-associated bronchiolitis causing severe restrictive lung disease in adults: report of three cases and literature review.

    STUDY OBJECTIVES: To characterize adult mycoplasma pneumoniae-induced bronchiolitis requiring hospitalization. DESIGN: We encountered an adult patient with severe bronchiolitis in the absence of pneumonia due to M. pneumoniae. To determine the relative frequency of such a condition, we retrospectively reviewed the medical records of adults over a 4-year period with a hospital discharge diagnosis of "bronchiolitis" from a university hospital. SETTING: University Hospital of the University of colorado health Sciences Center, Denver, CO. Study subjects: From 1994 to 1998, 10 adult inpatients were identified with a diagnosis of bronchiolitis. There were two with respiratory bronchiolitis, one with panbronchiolitis, one patient with bronchiolitis obliterans organizing pneumonia (BOOP), and six with acute inflammatory bronchiolitis. Including the initial patient, three had a definitive clinical diagnosis of Mycoplasma-associated bronchiolitis. RESULTS: The three adult patients with bronchiolitis due to M. pneumoniae are unusual because they occurred in the absence of radiographic features of a lobar or patchy alveolar pneumonia. Hospital admission was occasioned by the severity of symptoms and gas exchange abnormalities. One patient had bronchiolitis as well as organizing pneumonia (BOOP) that responded favorably to corticosteroid treatment. The other two had high-resolution CT findings diagnostic of an acute inflammatory bronchiolitis. One of the patients with inflammatory bronchiolitis had an unusual pattern of marked ventilation and perfusion defects localized predominantly to the left lung. All three had restrictive ventilatory impairment on physiologic testing. CONCLUSIONS: In adults, Mycoplasma-associated bronchiolitis without pneumonia is rarely reported, but in hospitalized patients, it may be more common than expected and may be associated with severe physiologic disturbances.

2/97. Constrictive bronchiolitis and ulcerative colitis.

    Pulmonary complications occur in an estimated 0.21% of patients with inflammatory bowel disease. The most common presentation of pulmonary manifestations is large airway disease, such as tracheobronchitis, chronic bronchitis or bronchiectasis. Small airway disease, such as constrictive bronchiolitis or bronchiolitis obliterans with organizing pneumonia, is less frequently reported, and is described as occurring in isolation from large airway disease. A case of a postcolectomy ulcerative colitis in a patient who has both large airway involvement, tracheobronchitis and bronchiectasis, and constrictive bronchiolitis is presented. ( info)

3/97. Diffuse panbronchiolitis, the first case reports in thailand.

    Diffuse panbronchiolitis (DPB) is an important cause of progressive obstructive lung or chronic suppurative lung disease in the far east (japan, china and korea). It is a distinctive sinobronchial syndrome with typical radiological and histologic features. We have identified three patients who have typical clinical manifestation and pathological confirmation. DPB should be suspected in patients who have clinical manifestations of chronic cough, productive sputum and shortness of breath. The chest radiograph often shows diffuse nodular shadows on a background of hyperinflated lungs. High resolution computed tomographic (HRCT) can guide the diagnosis and differentiate from other diseases. Finally, the most important issue of DPB is the treatment. Chronic treatment with low-dose erythromycin can improve the survival of patients. ( info)

4/97. lambert-eaton myasthenic syndrome associated with idiopathic thrombocytopenic purpura and diffuse panbronchiolitis: long-term remission after a course of intravenous immunoglobulin combined with low-dose prednisolone.

    We report a case of lambert-eaton myasthenic syndrome (LEMS) associated with idiopathic thrombocytopenic purpura (ITP) and diffuse panbronchiolitis (DPB). An extensive search for malignancy yielded negative results. Interestingly, ITP and DPB developed simultaneously when the patient suffered from myasthenic symptoms. This is the first report in the Japanese or English literature of an association of LEMS, ITP, and DPB. The use of cholinesterase blocker alone did not improve the myasthenic symptoms, and the symptoms and signs relapsed with the tapering of prednisolone (PSL) dosage. However, after administration of immunoglobulin (IVIG) (0.4 g/kg/day x 5 days), low-dose PSL (20 mg/day) alleviated the LEMS and ITP, and the diseases have remained in remission for 8 months without additional IVIG. We suspect that there is a synergistic relationship between IVIG and PSL. ( info)

5/97. Bronchiolitis in Kartagener's syndrome.

    The association of diffuse bronchiolitis in patients with Kartagener's syndrome (KS) has not been reported previously. The aim of this study was to present the morphological characteristics of bronchiolitis in patients with KS. Eight patients (four males, four females; mean age 37.9 /-18.7 yrs), clinically diagnosed as KS with the classical triad of chronic pansinusitis, bronchiectasis and situs in versus with dextrocardia, were evaluated. Routine chest radiography showed bronchiectasis and dextrocardia in all patients. Chest computed tomography (CT) showed diffuse centrilobular small nodules up to 2 mm in diameter throughout both lungs in six out of eight patients. Pulmonary function tests revealed marked obstructive impairment in all patients (forced expiratory volume in one second 57.0 /-11.3%, residual volume/total lung capacity 45. /-12.7%, maximum midexpiratory flow 0.92 /-0.72 L x s(-1), forced vital capacity 74.1 /-12.2% (all mean /- SD)). The examination of cilial movement of the bronchus revealed immotility in all of the five patients examined. The ultrastructure showed ciliary dynein arm defects in all patients. Histopathological examination of lung specimens obtained at autopsy or by video-assisted thoracoscopic surgery showed obliterative thickening of the walls of the membranous bronchioli with infiltration of lymphocytes, plasma cells and neutrophils, but most of the distal respiratory bronchioli were spared and alveolar spaces were overinflated. Pathologically, the diffuse centrilobular small nodules on the chest CT mainly corresponded to membranous bronchiolitis. This is the first report demonstrating that the association of diffuse bronchiolitis might be one of the characteristic features of the lung in Kartagener's syndrome. ( info)

6/97. Respiratory bronchiolitis associated with severe dyspnea, exertional hypoxemia, and clubbing.

    Respiratory bronchiolitis-associated interstitial lung disease (RBILD) is a distinct clinicopathologic disease described almost exclusively in cigarette smokers.(1) (2) The disease usually presents with mild symptoms and is associated with a good prognosis. (2) Severe lung dysfunction has not been reported with RBILD, which is often confused clinically and radiographically with desquamative interstitial lung disease or idiopathic pulmonary fibrosis (IPF). Two patients with RBILD who developed severe dyspnea, hypoxemia, and clubbing are described. Initially, IPF was diagnosed in both patients. The severity of symptoms was such that the first patient's room air saturation was 85% and the second patient had severe impairment of lung function, with FEV(1) of 39% and FVC of 40%. Advanced lung disease required supplemental home oxygen therapy in the first patient and referral for lung transplant evaluation in the second patient. After a detailed review of histology revealed a diagnosis of RBILD, both patients were encouraged to stop smoking; smoking cessation led to considerable improvement in symptoms and lung function tests. We conclude that advanced lung dysfunction occurs in some patients with RBILD and should not dissuade that diagnosis. ( info)

7/97. Diffuse panbronchiolitis in latin america.

    Diffuse panbronchiolitis (DPB) is a unusual form of bronchiolar disease that has been reported almost exclusively in Asians. We describe DPB in a non-Asian Brazilian citizen who has never traveled outside the country. The clinical, radiographic, and histologic features of this case resemble those described in Japanese patients. The present case shows that DPB, although rare in Western countries, is not a disease restricted to asia. It always should be considered in the differential diagnosis of nodular radiographic opacities associated with airflow limitation, especially in non-smokers with a history of chronic sinusitis.

8/97. An autopsy case of diffuse panbronchiolitis associated with lung cancer.

    The prognosis of diffuse panbronchiolitis (DPB) has been remarkably improved after the development of low-dose erythromycin therapy, possibly due to anti-inflammatory rather than anti-infective mechanisms. Interestingly, DPB associated with lung cancer is quite rare. Here, we report an autopsy case of DPB who developed lung cancer after a long successful therapy with low-dose erythromycin. ( info)

9/97. A report of the first three cases of diffuse panbronchiolitis in malaysia.

    Three cases of diffuse panbronchiolitis (DPB) occurring in two Malaysian Chinese patients and one Malay patient are reported. They had similar clinical, radiological and physiological features which are characteristic of DPB. The diagnosis in one of the cases was confirmed histologically by transbronchial lung biopsy. These could be the first three cases identified in malaysia. ( info)

10/97. Respiratory bronchiolitis: an unusual cause of pulmonary infiltrates in a pregnant woman.

    Numerous mechanical, biochemical, and immunologic changes occur during pregnancy. Because of these changes, pregnant women are more susceptible to infection, thromboembolic disease, exacerbation of underlying immunologic disease, and heart failure than women who are not pregnant. The differential diagnosis of diffuse pulmonary infiltrates in a pregnant woman is broad; thus, the work-up can be very challenging. If the patient fails to respond to conservative measures, such as antibiotics, the cause of the infiltrate must be aggressively evaluated because the treatment may be essential for the survival of the mother and fetus. We report a case of a pregnant woman who presented with diffuse bilateral infiltrates. After video-assisted thoracoscopic lung biopsy, this patient was found to have respiratory bronchiolitis, a disease not previously reported during pregnancy. Treatment with glucocorticoids resulted in a prompt improvement in symptoms. ( info)
