Three patients with severe progressive interstitial lung disease refractory to steroid therapy were treated with immunosuppressive drugs. Biopsy material of one showed mainly fibrosis, while that of the second showed interstitial pneumonitis as well; both patients received azathioprine. Cyclophosphamide was employed in the third patient with systemic vasculitis and massive hemoptysis. All patients had reduced lung volumes and abnormal gas exchange, which continued to worsen on high doses of steroids. In patients 1 and 2, there was long-term stabilization of lung function, while pulmonary physiologic abnormalities in the patient with vasculitis reverted to normal on five months of cyclophosphamide. Although the etiology of most forms of interstitial lung disease is unknown, several reports suggest at least a partial immunologic basis. Abatement in progression of disease in this small series would suggest that a trial of immunosuppressive drugs be considered in interstitial lung disease when steroid therapy fails.

Fibreoptic bronchoscopy was introduced more than 10 years ago and is now in many centres a routine diagnostic procedure, having superseded rigid bronchoscopy. Its major role is in the diagnosis of bronchial carcinoma, where the results are as good as, if not better than, results with the rigid instrument. Other major applications have been found in investigating haemoptysis, transbronchial lung biopsy in interstitial lung disease, and in the critically ill patient in the intensive care unit. More recently, the instrument has been used to perform bronchoalveolar lavage in investigating interstitial lung diseases and to enable lobar and segmental lung function studies to be performed. Fibreoptic bronchoscopy is a major advance in the diagnosis of pulmonary diseases, but there will always be times when rigid bronchoscopy is preferable.

The diagnosis of lymphangioleiomyomatosis was established in a 35-year-old woman with hemoptysis, mild cough, and dyspnea based on histologic review of results of a transbronchial biopsy correlated with high-resolution computed tomographic scan findings. A chest x-ray film revealed diffuse interstitial lung disease, and a high-resolution computed tomographic scan showed diffuse cystic changes throughout both lungs. The transbronchial biopsy specimen revealed cystic changes and a patchy, sometimes nodular proliferation of smooth muscle that focally expanded the interstitium suggestive of lymphangioleiomyomatosis. The smooth-muscle nature of the cells was confirmed by positive immunohistochemical stains for actin and desmin; positive staining for HMB-45 was also observed. Although the diagnosis of lymphangioleiomyomatosis usually requires an open lung biopsy, this case shows that rarely, in the appropriate clinical setting, the diagnosis may be rendered based on results of a transbronchial biopsy in conjunction with findings from ancillary immunohistochemical studies and high-resolution computed tomography.

Respiratory bronchiolitis associated interstitial lung disease is an uncommon condition in current or ex-smokers. The presentation is non-specific, but haemoptysis is uncommonly reported in this condition. We report the case of a 25-year-old woman who presented with significant haemoptysis, dyspnoea, reduced transfer factor and normal clinical examination. In addition, a Medline literature search was performed to review the clinical features and prognosis of this disease. Other causes of haemoptysis were excluded with extensive investigation. The diagnosis was made on thoracoscopic lung biopsy. The patient had significant postoperative complications of prolonged air leak and hydropneumothorax requiring further surgery and prolonged hospital stay. Advice regarding smoking cessation was given. Her pulmonary physiology remains abnormal on follow up but symptoms have improved. Respiratory bronchiolitis-ILD may present with normal examination and radiology. Haemoptysis in this case may have been associated with the underlying disease but could have been incidental. Diagnosis, in general, requires lung biopsy. As in this patient, lung function does not appear to improve significantly on follow up.

Inhalation of dusts is an important cause of interstitial lung disease in the tropical countries such as India. While dusts of organic origin, such as the cotton dust causing byssinosis, generally cause bronchial or bronchiolar involvement and hypersensitivity pneumonitis, inorganic metallic dusts cause progressive pulmonary fibrosis. Silicosis, coal workers' pneumoconiosis, and asbestosis are the three most commonly recognized forms of pneumoconiotic pulmonary fibrosis. Pulmonary tuberculosis is an important complication seen in up to 50% of patients of silicosis in some reports from India. The presentation is generally chronic, although acute and accelerated forms of silicosis are known when the exposures are heavy. Breathlessness, dry cough, and general constitutional symptoms are commonly seen. Patients with silicotuberculosis or other forms of infection may also have significant expectoration, hemoptysis, fever, and rapid progression. Respiratory failure and chronic cor pulmonale occur in the later stages. The diagnosis is easily established if the occupational history is available. Dense nodular opacities on chest roentgenograms, which may be large in patients with massive pulmonary fibrosis, are characteristic. Emphysematous changes generally appear in advanced stages or in patients who smoke. Bronchoalveolar lavage and/or lung biopsy may occasionally be required to establish or exclude other causes of interstitial lung disease. Treatment is largely palliative, although a variety of drugs including corticosteroids and procedures such as whole lung lavage have been tried. None of these methods has yet been found successful in the treatment. Preventive safety steps, including removal of the patient from the site of exposure, are the only effective strategies to control disease progression.

The cases of 6 patients (4 men, 2 women) with antisynthetase syndrome are reported. The mean age was 60 years and the most frequent symptom was increasing dyspnea (4 patients). One of the remaining 2 patients had hemoptysis and the last was asymptomatic. Systemic symptoms included Raynaud's phenomenon (2 patients), arthritis in hands (3) and muscle impairment (4). Chest films showed linear interstitial infiltrates of varying severity in 5 patients; the patient without such infiltrates also suffered silicosis. Functional assessment showed restrictive impairment in 4 patients; of the remaining 2 patients, 1 had chronic obstructive pulmonary disease and 1 had normal function. The antisynthetase antibody (ASAB) detected was anti-Jo-1 in 4 cases, anti-PL-12 in 1 case, and unidentified in 1 case. The course of disease was satisfactory for 5 patients. ASAB analysis is useful for studying idiopathic interstitial lung disease.

Fibreoptic bronchoscopy (FOB) helps in visualisation of the endobronchial tree. Fibreoptic bronchoscopies were done in 429 cases between January 1999 and January 2000 [322 men (75.1%) and 107 women (24.9%)]. Patients were between 12 and 89 years of age (mean+/- SD = 49 +/- 15.1 years). Of which, 196 (45.7%) had lung cancer and 233 (54.4%) had non-malignant disease [Tuberculosis (TB) 26, miliary TB 16, non-resolving pneumonia 29, atypical pneumonia 10, bronchiectasis 11, aspergillosis 12, sarcoidosis 17, interstitial lung disease (ILD) 20, haemoptysis with normal chest x-ray 13 and miscellaneous 79]. In this series of 429 patients a significant number of patients (n = 127) presented with fever (38 malignant and 89 non-malignant disease, p < 0.0001), 137 had haemoptysis (74 malignant and 63 non-malignant disease, p < 0.01), 89 had chest pain (61 malignant and 28 non-malignant disease, p < 0.0001) and 29 patients presented with complaint of anorexia (21 malignant and 8 non-malignant disease, p < 0.003). High prevalence of lung lesions in the right upper lobe [10.4% (43 of 411)] and left main bronchus [12% (49 of 411)] was observed. Left upper lobe showed 8.7% (36 patients) lesions and right middle lobe showed 5.5% (23 patients) lesions. In 143 (34.8%) patients, FOB findings were normal. Out of 407 patients, FOB was suggestive of necrotic/nodular growth in 159 patients (39.1%), infiltrative growth in 8 patients (1.9%), and extrinsic compression was found in 39 patients (9.6%). In 143 patients (35.2%) no endobronchial growth was seen. Bronchial biopsy (BB) was performed in 162 (37.8%) patients, transbronchial lung biopsy in 56 patients (13.1%), bronchial washing for cytology in 350 patients (81.5%), bronchial washing for AFB in 302 patients (70.3%), bronchial washing for culture in 67 patients (15.6%), bronchial washing for fungus in 64 patients (14.9%) and Pneumocystis carinii infection was looked for in 6 patients (1.4%). Postbronchoscopy complications were recorded as follows: Early termination of FOB due to decreased O2 saturation in 10 cases (2.4%), postbiopsy bleeding in 5 cases (1.2%), post FOB fever in 5 cases (1.2%), chest pain in 7 patients (1.7%) and pneumothorax occurred in 2 patients (0.5%). FOB performed in outpatient setting is a useful and safe modality. Most patients in whom FOB was done in the present setup had suspected lung cancer. No major complications were encountered.

A 28-year-old girl suffering from lysinuric protein intolerance was referred on account of severe chronic respiratory failure. Since childhood she had failure to thrive with chronic hyperammonaemia and interstitial lung disease but normal respiratory function. At the age of 21, she experienced haemoptysis and worsening of the respiratory disease. CT scan of the chest showed bilateral, symmetrical ground glass opacities and subpleural cysts. At the age of 25, nocturnal non-invasive ventilation was initiated. Lysinuric protein intolerance is an exceptional genetic cause of interstitial lung disease.

Idiopathic pulmonary hemosiderosis (IPH) is a rare disorder (triad of iron-deficiency anemia, hemoptysis, and alveolar infiltrates). A 3-year-old male presented with mild fever, breathlessness, dry cough, and bluish nail discoloration for 8 days. He had required five blood transfusions in the past 1 year (last transfusion was given 4 months ago). He had a respiratory rate of 58/min with respiratory distress, cyanosis, and grade III clubbing. Respiratory system examination was normal. Several previous reports of hemoglobin were as low as 3.6 g/dl with hypochromic and microcytic anemia. There were transient increases in the hemoglobin and normalization of red cell morphology with blood transfusions. Serum iron, G6PD enzyme assay, hemoglobin electrophoresis, the sickling test, Coomb's test, stool and urine analysis, and a Meckel's scan were normal. HIV antibody and dsDNA were negative. The chest radiograph revealed symmetrical patchy infiltrates sparing lung apices (confirmed on high-resolution computed tomography). Lung biopsy diagnosed pulmonary hemosiderosis (interstitial lung disease with hemosiderin-laden macrophages scattered in the alveoli and areas of fibrosis in the alveolar septa). The patient showed marked clinical improvement in 10 days of therapy with prednisolone. IPH should be listed in the differential diagnosis of a child presenting with unexplained hypochromic, microcytic anemia and respiratory symptoms.

Pulmonary toxicity is rarely seen with most commonly used targeted therapies. The endothelial growth factor receptor (EGFR) small-molecule tyrosine kinase inhibitors (TKIs) gefitinib and erlotinib can cause interstitial lung disease (ILD). BCR-ABL tyrosine kinase inhibitors imatinib and dasatinib can cause pleural effusions. Infusion-related bronchospasm is common with the monoclonal antibodies to EGFR cetuximab and panitumumab, and case reports of bronchiolitis and pulmonary fibrosis have been described. Up to one-sixth of patients taking mammalian target of rapamycin (mTOR) inhibitors get a reversible interstitial pneumonitis. Bevacizumab, the monoclonal antibody to vascular endothelial growth factor (VEGF), has been associated with hemoptysis and pulmonary embolism particularly in patients with squamous cell lung cancer. Infusion-related bronchospasms, acute respiratory distress syndrome (ARDS), and interstitial pneumonitis can be seen with the anti-lymphocyte monoclonal antibodies rituximab, ofatumumab, and alemtuzumab. While most pulmonary toxicities from these therapies are mild and resolve promptly with dose reduction or discontinuation, it is important for the clinician to recognize these potential toxicities when faced with treatment-related complications. Discerning these pulmonary adverse effects may help in making decisions on diagnostic testing and therapy, particularly for those with pulmonary and cardiovascular co-morbidities.
