A 58-year-old woman was admitted to our hospital because of recurrent fever, severe cough and sputum. Chest radiological examinations showed diffuse reticulonodular opacities in both lung fields. Interstitial pneumonia with probable polymyositis was diagnosed. Serum surfactant protein (SP)-A, SP-D and KL-6, which are new interstitial lung disease markers, showed values significantly higher than cutoff levels. The markers increased more in parallel with the rapid development of respiratory insufficiency, CPK level, myalgia and proximal muscle weakness. Treatment with a high dose of corticosteroid and the following gradual decrease over 8 months led to clinical and radiological improvement, with normalization of values of the markers. These markers may therefore be reliable indicators of therapeutic success. However, these markers underwent different respective changes during the first 2 months. SP-A reached a maximum at the start of the treatment, while SP-D and KL-6 peaked at 5 and 10 days, respectively, after the treatment was initiated. This discrepancy demonstrates that the markers reach the bloodstream by diverse mechanisms and are useful for analyzing pathophysiological alterations in the lung in the early stages of treatment.

A 29-year-old man was admitted to our hospital because of fever elevation, dry cough, malaise, skin eruption, and dyspnea with hypoxemia. His serum levels of surfactant protein (SP) -A and SP-D were markedly high, but serum KL-6 was not. He was diagnosed as acute eosinophilic pneumonia (AEP) on the basis of CT imaging, bronchoalveolar lavage findings and the clinical course. He showed good response to steroid therapy and serum levels of SP-A and SP-D returned to almost normal levels. Our experience suggested that serum SP-A and SP-D might be helpful markers for monitoring the clinical course in AEP.

A 45-year-old Japanese electrical engineer was admitted to our department of internal medicine on August 12, 2003, because of a sudden high fever and severe hypoxic respiratory failure. At a barbecue with his family on August 3 beside a nearby river, he had been exposed to the smoke. From August 4 to 11, he had suffered fatigue, fever, dry cough and progressive dyspnea. On admission, his SpO2 was 84%, and computed tomography scanning showed patchy ground glass opacity, thickened bronchial walls, and bilateral pleural effusions. The eosinophil count in the bronchoalveolar lavage fluid (BALF) was increased to 52.4%. Noticeably, the KL-6, SP-A and SP-D levels in the serum were elevated to 197 U/ml, 188 ng/ml and 137 ng/ml, and their levels in BALF had also increased to 225 U/ml, 890 ng/ml and 1110 ng/ml, respectively. The lymphocyte stimulation test was negative, and the cultures of blood and BALF did not grow any pathogens. The patient had smoked 1 pack of per cigarettes day for 25 years and showed no sign of atopic illness. Acute eosinophilic pneumonia (AEP) was diagnosed, and responded dramatically to treatment with oxygen and corticosteroids. The dissociation between the normal KL-6 levels and the elevated SP-A and SP-D levels in the serum and BAL fluid may play an important role in cases of AEP.

A 37-year-old-woman was admitted to our hospital because of chest bilateral reticular shadow with fever, cough, general malaise and exertional dyspnea in the summer. A diagnosis of summer-type hypersensitivity pneumonitis (SHP) was made by radiological, serological and histological examinations. Her 10-year-old daughter had chest reticular shadows and similar symptoms. These two patients were positive for serum anti-Trichosporon cutaneum (T. asahii, T. mucoides) antibodies and T. asahii was identified from cultured samples obtained from their house. They recovered spontaneously after hospitalization or isolation from the antigen. We reviewed the clinical features in sixteen families with familial SHP reported in Japan. Children aged under 15 years old accounted for 34% and there was no gender difference among patients. This finding differs from the conventionally defined features of patients with SHP. Measurements of serum KL-6, SP-D and SP-A seem to be useful for auxiliary diagnosis and monitoring the disease activity of SHP, especially in pediatric cases who cannot undergo invasive evaluation.

The patient was a 61-year-old man diagnosed with rheumatoid arthritis (RA) in 2001. He initially received treatment at a nearby clinic, but his condition could not be satisfactorily controlled. He subsequently consulted our hospital during the same year. Although his symptoms improved in response to treatment at our hospital, slight fever, cough, and then high fever and dyspnea subsequently developed. A diagnosis of interstitial pneumonia was made on the basis of findings of diagnostic imaging. The time course of changes in serological markers, including surfactant protein A (SP-A), surfactant protein D (SP-D), and KL-6, as well as markers of inflammatory reaction and lactate dehydrogenase was examined to determine the clinical significance of serological markers in the management of interstitial pneumonia.

The characteristics of Pneumocystis carinii pneumonia (PCP) in patients with connective tissue diseases (CTDs) were examined retrospectively. Nine patients were enrolled in this study. Their mean age was 57.1 years. All the patients received a high-dose steroid or immunosuppressant. The onset (mean 6.6 days) of fever, cough, breathlessness, and geographical ground-glass opacities revealed by chest computed tomography was acute. The serum beta-D: -glucan level increased with a simultaneous increase in the Krebs von den Lungen (KL)-6 or surfactant protein D level. The serum immunoglobulin G (IgG) and albumin levels and the peripheral blood lymphocyte count at the onset of PCP were low, but only the serum IgG level decreased significantly. The patients were treated with trimethoprim-sulfamethoxazole or pentamidine isetionate. Six patients died eventually: two patients of progressive respiratory failure, two probably due to a recurrence of the PCP, and two with microbial respiratory infections other than PCP. Five of the six patients required mechanical ventilation. Three patients received secondary prophylaxis and survived. In conclusion, the acute onset was characteristic of PCP in patients with CTDs. High-dose steroids, immunosuppressants, and hypogammaglobulinemia are risk factors; and respiratory failure requiring mechanical ventilation, severe secondary infections, and a lack of secondary prophylaxis are poor prognostic factors. Secondary prophylaxis is recommended for all of these patients.

The sequential changes of the serum levels of KL-6, SP-D, and DLco were followed for a long term in a case of acute bird fancier's lung, A 52 years-old-male was admitted to our hospital because of cough, dyspnea on exertion and fever. He has been breeding 12 pigeons in home for the last five years. HRCT of the chest demonstrated diffuse centrilobular nodules and ground-glass opacities with mosaic pattern in bilateral lung fields. Bronchoalveolar lavage (BAL) showed an increased number of lymphocytes with a increased CD4/CD8 ratio, and transbronchial lung biopsy (TBLB) specimen revealed alveolitis with infiltration of lymphoid cells and Masson body in the air spaces. He was diagnosed as having bird fancier's lung because of the elevated antibodies against pigeon dropping extracts (PDE) in the serum and BALF. Respiratory failure continued after complete avoidance of contact with pigeons for a week. Clinical symptoms and chest X-ray findings improved markedly after administration of steroid, and he left the hospital to move into a new house. The serum levels of KL-6 and SP-D were unchanged by antigen avoidance, although those were returning to normal gradually after treatment of steroid. SP-D and KL-6 returned to normal in 8 months and 18 months respectively and DLco was also improved slowly in parallel with a decrease of these markers. These results suggest that the serum KL-6 level and DLco reflect the disease activity showing gradual recovery of alveolitis in such a long period.

An 88-year-old woman was admitted with acute appendicitis. She had been treated with prednisolone and home oxygen therapy for interstitial pneumonia. Her respiratory state on admission was Grade 2 of Hugh-Jones' classification, and plasma KL-6 and SP-D levels were high. Seven days after the admission, appendectomy was performed under spinal anesthesia. Spinal anesthesia was initiated by injecting 0.5% hyperbaric bupivacaine 2.0ml into L3-4 interspace, and achieved block level was up to T4. During the operation, her respiratory state was stable, but after the operation, dry cough, increase of body temperature, and dyspnea were observed. Chest roentgenogram revealed severe ground glass appearance and reticular shadows bilaterally. Steroid therapy for acute exacerbation of interstitial pneumonia was initiated, but she died on the 13th POD. This case teaches us to take a lot of care in the management of a patient with high plasma level of KL-6 and SP-D.

Cytology of tracheal aspirates, tracheal endoscopic and blood tests were carried out to 86 Thoroughbred racehorses presenting coughs or poor performance which were suspected to have lower respiratory tract disease (LRTD) to assess the conditions of the disorders. Racehorses were classified into coughing (66 horses) and non-coughing (20 horses) groups based on clinical symptoms. Nine Thoroughbred racehorses without respiratory abnormality were used as controls. Assessment of grades of airway mucus, cytology of tracheal aspirates and serum amyloid A (SAA), fibrinogen (Fbg) and pulmonary surfactant protein D (SP-D) measurements were performed. Relationships between age, gender and racing careers were also investigated to understand the characteristics of LRTD in racehorses. Mean age was significantly higher in non-coughing group compared to coughing group. Existence of racing career and number of starts were significantly greater in non-coughing group compared to coughing group. On the other hand, grades of airway mucus were significantly higher in coughing group compared to control group. Percentages of neutrophils in tracheal aspirates were significantly higher in coughing group compared to non-coughing and control groups. SAA, Fbg and SP-D were higher in coughing group compared to non-coughing and control groups indicating that condition of coughing group is in the acute phase. Positive rate of inflammatory airway disease was significantly higher in coughing and non-coughing groups compared to control group. It was concluded that carrying out comprehensive evaluation including investigation on SAA, Fbg and SP-D analysis with airway assessment to Thoroughbred racehorses which were suspected to have LRTD are useful procedure to understand the pathological condition which aid to initiate appropriate treatment, prognosis judgment or to advise trainers to consider altering training regimen.

Interstitial lung disease (ILD) is becoming one of the main causes of death of patients with systemic sclerosis (SSc). The prevalence of ILD associated with SSc (SSc-ILD) varies from 33% to 100% according to diagnostic methods. Clinical features such as dyspnea on exertion, dry cough, and chest pains are not specific and usually late-appearing, implying more specific tests in the diagnostic, prognosis, and follow-up of ILD in patients with SSc. High resolution thoracic CT scanner (HRCT) is more sensitive than chest X-ray in the detection of SSc-ILD. Pulmonary function tests (PFT) are non-invasive and periodically used to assess the impacts of SSc on respiratory function. Diagnostic values of bronchoalveolar lavage and histological examination on lung biopsy are controversial. However, these techniques are essential for studying cellular and molecular mechanisms underlying the pathophysiology of SSc-ILD. Several biomarkers such as surfactant-A (SP-A), -D (SP-D), mucin-like high molecular weight glycoprotein (KL-6), and chemokine CCL-18 have been implicated in SSc-PID. Serum levels of these proteins are correlated with the severity of SSc-ILD, as assessed by HRCT and/or PFT. Finally, alveolar concentration of exhaled nitric oxide can be used to screen SSc patients with high risk of deterioration of respiratory function, in whom immunosuppressant treatment could be useful in preventing the evolution to irreversible lung fibrosis.
