Three cases of cholesterol interstitial pneumonia in patients 3, 9 and 10 years of age respectively are reported. All three were born in Island of Reunion. Two were sisters. All had failure to thrive, dyspnea on rest and clubbing. Respiratory symptoms had appeared early in infancy. Open pulmonary biopsy was diagnostic. Prognosis was poor the boy dying at 4 years of age and severe respiratory insufficiency at 9 or 10 years in the two girls. Current etiological investigations were non contributory. However a profile of chronic infection with Epstein Barr virus (EBV) was found in each case while serological profiles ruled out infection with a virus of the herpes group virus (cytomegalovirus, herpes simplex). The possible role of EBV as an etiological agent of cholesterol pneumonia is discussed and genetic or environmental factors as well.

Two major pulmonary diseases were defined on the basis of lung biopsies in 15 children with acquired immune deficiency syndrome (AIDS) or AIDS-related complex. Pneumocystis carinii pneumonia was observed in eight children, and pulmonary lymphoid hyperplasia in six. One child had nonspecific interstitial pneumonitis. Children with P. carinii pneumonia had more severe hypoxemia, with higher alveolar-arterial oxygen gradients, and higher isomorphic elevations of serum lactate dehydrogenase. Clinically, children with pulmonary lymphoid hyperplasia were older, and had digital clubbing, parotid gland enlargement, and elevated serum IgG levels. Results of serologic assays and lung tissue analysis were suggestive of persistent Epstein-Barr virus infection exclusively in patients with pulmonary lymphoid hyperplasia. Recognition of the clinical and laboratory findings characteristic of each entity may assist in the differential diagnosis without the need of surgical biopsy.

To assess the role of chest radiography in the differential diagnosis of bronchiolitis obliterans organizing pneumonia (BOOP) and usual interstitial pneumonia (UIP), records of 34 patients with biopsy-proved BOOP (16 patients) or UIP (18 patients) were reviewed. Chest radiographs taken before biopsy were available in 26 patients, clinical information in 33, and pulmonary function data in 22. These data were reviewed independently, without knowledge of the pathologic diagnosis. The clinical symptoms of BOOP were similar to those of UIP, although the duration of symptoms was longer in UIP (P less than .05), and the prevalence of systemic symptoms was higher in BOOP (P less than .025). The physical findings were similar except that finger clubbing was more common in patients with UIP than in those with BOOP (P less than .01). There was no significant difference in lung volumes, flows, or diffusing capacity between BOOP and UIP. The chest radiograph showed distinguishing features between UIP and BOOP in 23 of 26 patients. The most characteristic radiologic finding in BOOP was the presence of patchy areas of air-space consolidation (eight of 11 patients).

This report is based on 43 cases where a diagnosis of either bronchiolitis obliterans with organizing pneumonia (BOOP), usual interstitial pneumonia (UIP), or small airways disease (SAD) was established by lung biopsy. The severity of histologic abnormalities in the peripheral airways and interstitial spaces were measured on these biopsies using semiquantitative techniques and compared with the clinical data available in 42 of 43 cases, preoperative chest radiographs in 31 of 43, and preoperative pulmonary function tests in 29 of 43. The data show that when a diagnosis of BOOP was made, there was a higher total pathologic score for membraneous bronchiolitis (MB) and respiratory bronchiolitis (RB) than for UIP and SAD (p less than 0.005). This was due to peribronchiolar inflammation and the presence of loose connective tissue in the RB lumen. The pathologic changes in the interstitial space were less severe in SAD than in BOOP or UIP (p less than 0.005). Clubbing was more frequent in UIP (p less than 0.01), and symptoms were of shorter duration in BOOP (p less than 0.05). The radiographic assessment showed that the characteristic finding in BOOP was patchy air-space consolidation, a finding that was not present in UIP or SAD.

A case of hypertrophic osteoarthropathy in a 5-year-old Saudi boy is presented. The child developed painful joints, was found to have clubbing of fingers and radiologically hypertrophic osteoarthropathy was demonstrated. The underlying cause of the condition was ingestion of animal fat in infancy, with a history of ghee oil aspiration which caused a chronic lung inflammation, lipoid pneumonia, proven by lung biopsy.

Interstitial lung diseases (ILD) are disorders of the lower respiratory tract, characterized by chronic inflammation of the lung parenchyma, varying degree of fibrosis, derangement of the alveolar walls and loss of the functional alveolar capillary units. ILD are relatively uncommon in children. Most of the interstitial lung diseases have no known etiology. In children, common diseases associated with ILD include viral respiratory tract infections (RSV, parainfluenza, etc.), gastroesophageal reflux, idiopathic pulmonary fibrosis, pulmonary hemosiderosis, eosinophilic pneumonia, pneumonitis associated with AIDS, etc. Chronic inflammation of the alveoli (alveolitis), the initial injury in ILD, and several mediators released from inflammatory cells (eosinophils, neutrophils and macrophages) can cause fibrosis and derangement of alveolar walls. Dyspnea and a non-productive cough are the cardinal symptoms of ILD. Other findings include chest pain, hemoptysis and weight loss. Clubbing of fingers occur in approximately 50 per cent of cases. Diagnosis is based on a combination of history, clinical findings, radiographic findings, pulmonary function tests and histologic findings. Open lung biopsy has been very helpful in providing information regarding the extent and nature of the damage, prognosis and response to therapy. There are 3 main aspects in the treatment of ILD. The most important step is to identify and eliminate the cause. The second is suppression of the inflammation. The third is supportive and symptomatic treatment. Corticosteroids are the drugs commonly used for suppression of inflammation. Immunosuppressive drugs (azathioprine, cyclophosphamide) have also been tried. Lung transplantation and heart transplantation have been successfully achieved in selected patients. The results of therapy should be regularly monitored by clinical symptoms, chest radiographs and serial pulmonary function studies.

A 27-year old female from Nairobi was admitted to the medical wards of the Kenyatta National Hospital in May 1991. She presented with a 4-week history of productive cough, fever, weight loss, and night sweats. She acknowledged a history of contact with a patient known to have pulmonary tuberculosis. She has never received a blood transfusion. She was single and para 3 + 0. Examination revealed a sick patient, with moderate pallor, fever of 38 degrees Celsius, and who was wasted with moderate dehydration and oral thrush. There was no finger clubbing, lymphadenopathy, or pedal edema. Chest examination revealed bilateral basal pneumonia. The spleen was palpable 4 cm below the costal margin; the liver was not enlarged. The rest of the examination was normal. On admission, complete blood count showed a haemoglobin of 5.4 g/dl, total white cells were 12.5 x 10-9/L, with 82% polymorphonuclear cells and 18% lymphocytes, erythrocyte sedimentation rate (ESR) was 85 mm/hour, and platelet count was normal. The anemia was normocytic, normochromic, and no malaria parasites were seen. Urea and electrolytes and liver function tests were normal. Sputum showed no acid fast bacilli on Ziel-Neelson Stain. HIV-1 antibodies were positive by enzyme-linked immunosorbent assay (ELISA) and Western blot. Bone marrow aspirate revealed a hypercellular marrow with reversed M:E ration, dyserythropoesis, reticulum cell hyperplasia, plentiful golden yellow pigment, and clumps of Histoplasma capsulatum. Chest X-ray showed bilateral basal pneumonia. She was treated with antibiotics and intravenous fluids, but she remained febrile, her general condition progressively deteriorated, and she died a week after admission. Treatment for histoplasmosis had not been commenced, and no postmortem examination was carried out.

We investigated the frequency of finger clubbing in 150 HIV-infected children consecutively hospitalized for acute pneumonia in South Africa and described associated clinical, laboratory and radiological features. Clubbing occurred in 30 of 150 (20%) HIV-infected children compared with one of 99 (1%) HIV-negative control patients, p < 0.001. Clubbing was associated with lower presenting heart and respiratory rates and enlarged parotid glands. Total and CD4 + lymphocytes, CD4:CD8 ratio and LDH were lower in children with clubbing, but serum protein and gammaglobulin were higher. No differences in the prevalence or type of microbial pathogens were found between the two groups. Clubbing was associated with a radiological diagnosis of LIP. Children with clubbing had a lower in-hospital mortality rate than those without clubbing (6.7% vs 24.2%, p = 0.035). In geographical areas with high HIV seroprevalence rates, the presence of clubbing in a child hospitalized for respiratory disease should raise the suspicion of HIV infection.

In a 59-year-old male patient, chronic dry cough and dyspnoea on exertion preexisting for several years became rapidly progressive within a few weeks prior to hospitalisation. He died one month after admission from respiratory failure. Three months before admission, history, pulmonary function tests, and computed tomography (CT) of the chest revealed no evidence of asthma, COPD, or any other lung disease. Clinical examination showed no clubbing, but end-inspiratory velcro-rales were audible over both lungs. Inhaled steroids and diuretics did not bring clinical amelioration. On admission there were basal consolidations, bronchiectases, and predominant fibrotic changes with honeycombing and subpleural thickening over both lungs, in the absence of any ground-glass pattern in the CT. At the same time lymphocytosis predominated in bronchoalveolar lavage (BAL). The search for pneumonia, viral infection, tumour, vasculitis, or a drug-related disorder remained negative. Pathological examination at autopsy showed nonuniform fibrosing alveolitis.

A 65-year-old male developed progressive dry cough and digital clubbing after starting rituximab-CHOP chemotherapy for non-Hodgkin lymphoma. A lung biopsy showed loose non-necrotic granulomas in a background of mild fibrosis and rare eosinophils, compatible with a drug-induced hypersensitivity pneumonia. Associated manifestations of this hypersensitivity reaction were a high eosinophil count, elevated serum levels of immunoglobulin E, and a skin rash consistent with pigmented purpuric dermatitis (Schamberg disease). Corticosteroids were marginally efficacious in treating this reaction. Few similar reactions have since been described, 2 of them ultimately fatal, but none was associated with pulmonary hemorrhage. A 2.5:1 ratio between the interstitial alveolar T4/T8 lymphocytes in our case is similar to the findings in methotrexate-induced pneumonitis and farmer lung disease. This report documents the serologic and immunohistologic findings associated with a pulmonary interstitial reaction to rituximab. A review of the pertinent literature is provided. The possible pathogenetic mechanisms, including the role of cytokines, cytotoxic T-lymphocytes and CD 20 positive T-cells in relation to the administration of rituximab are discussed.
