D-penicillamine (DPA) leads to side effects in different ways: collagen and elastin crosslinking are inhibited, which results in thin and vulnerable skin, cutis laxa, elastosis perforans serpiginosa, wound healing defects and embryopathy. Toxic influences effect thrombo- and leukocytopenia (incidence 5-15%), gastrointestinal disturbances (10-30%), changes or loss of taste (5-30%), loss of hair (1-2%), and partly proteinuria (5-20%). Acute hypersensitive reactions include DPA-allergy (2-10%). Severe adverse effects are autoimmune phenomena such as pemphigus, DPA-induced lupus erythematosus, polymyositis/dermatomyositis, membranous glomerulopathy and hypersensitivity pneumonitis (like Good-pasture's syndrome) and myasthenia (all less than 1%). In addition there are a number of rare side effects, often single observations. Risk factors include a genetic disposition (especially HLA-B8 and -DR3), poor sulphoxidizers and, to a certain degree, higher age. During pregnancy and in clinically relevant disturbances of bone marrow, liver and renal function DPA is contraindicated. The total incidence of side effects amounts to 30-60%, the withdrawal rate is 20-30%; therefore clear indications and a regular survey of DPA therapy are necessary.

Extrinsic Allergic Alveolitis (EAA) is a disease characterized by an exaggerated immune response to inhaled organic dusts that can result in alveolar, and occasionally bronchiolar, damage. This damage can disappear completely with the elimination of the antigen and/or treatment with anti-inflammatory agents. Nonetheless, an important group of these patients do not improve; the inflammatory reaction persists. With time, this results in the deposit of abnormal connective, tissue with respect to its quantity and quality, in the pulmonary interstitium destroying the normal parenchymal architecture and making gas exchange impossible. The most common cause of this disease is inhalation of pigeon antigen with a 5:1 predominance in women. Pregnancy has been considered as a case of allotransplantation that produces in the mother a relative hyporeactive condition. In modifying the immune response to the fetus, it is also modified to other foreign antigens. In this work, we studied 80 cases of EAA, 67 females and 13 males. Of the 67 women, 11 (17.1%) presented with the disease after delivery. Symptoms began from 5 days to 7 months after delivery. Eight of the 11 women had been in contact with the antigen before the beginning of the pregnancy without showing symptoms until after delivery. In 4 cases, there had been contact with the antigen in other pregnancies, without symptoms. EAA is a disease involving the immune system in which changes can be seen in its development during pregnancy, as is also seen in other immune diseases, such as Lupus Erythematosus, Rheumatoid Arthritis and other connective tissue diseases. During pregnancy, the mother becomes tolerant. There is a decrease in non-self recognition.(ABSTRACT TRUNCATED AT 250 WORDS)

Although electron microscopy no longer enjoys the important role in the diagnosis of interstitial lung diseases that it had in the 1960s and 1970s, it remains an important adjunct in the differential diagnosis of certain pulmonary diseases. Examples include various manifestations of systemic lupus erythematous pneumonitis, in which the presence of tubuloreticular structures and electron-dense deposits are useful for diagnosis; immotile cilia disorders, in which qualitative and now quantitative studies of the cilia of respiratory epithelial cells can help to establish the diagnosis; infections by viruses and other subcellular microorganisms as shown by the role played by electron microscopy in the initial diagnosis of the Hantavirus pulmonary syndrome; pneumoconioses, in which, in conjunction with elemental analysis probes, scanning electron microscopy is of critical importance in establishing the presence of offending foreign compounds in lung tissue or fluids; pulmonary fibrilloses, such as amyloidosis, light chain disease, and fibrillary glomerulonephritis, affecting the lung; and cases of alveolar proteinosis or Langerhans cell granulomatosis diagnosed from fluids such as bronchoalveolar lavages or small tissue samples. As important, electron microscopy remains of enormous usefulness in the study of early structural events leading to the pathogenesis of diseases. For example, recent uses of the technique have focused on the alveolar-capillary wall damage induced by alveolitis in hypersensitivity pneumonitis and sarcoidosis. In summary, electron microscopy remains a useful method in the study and diagnosis of some interstitial lung diseases, but because of its expense it is incumbent on the clinician to use good judgment in the selection of cases and diseases for study by this method.

Statins inhibit the 3-hydroxy-3-methylglutaryl coenzyme A reductase, reduce the serum level of low-density lipoprotein cholesterol, and are extensively prescribed to prevent cardiovascular mortality and morbidity. Few systemic adverse effects, such as pseudopolymyositis, lupus-like syndromes, and anecdotal hypersensitivity pneumonitis, have been reported. A simvastatin-induced diffuse interstitial pneumonia associated with a nonspecific interstitial pneumonia pattern at histological analysis is repoted here. Ultrastructural analysis showed a diffuse cytoplasmic accumulation of intralysosomial lamellar inclusions in type II pneumonocytes, histiocytes and endothelial cells, suggesting a shared pathogenesis with amphiphilic drug-induced toxic lung injury. Because statins are increasingly prescribed, statin-induced interstitial lung disorders may be more frequently observed and early recognition will be required.

The antibiotic minocycline, which is used in the treatment of acne, has been associated with various pulmonary complications such as pulmonary lupus and hypersensitivity pneumonitis. We now report a particularly severe case of minocycline-related pulmonary toxicity that was characterized by a relapsing form of hypersensitivity eosinophilic pneumonia complicated by acute respiratory failure.

Rituximab (RTX), a mouse/human chimeric anti-CD20 IgG1 monoclonal antibody has been effectively used as a single agent or in combination with chemotherapy regimen to treat lymphoma since 1997. In addition, it has been used to treat idiopathic thrombocytopenic purpura, systemic lupus erythematous, rheumatoid arthritis, and autoimmune hemolytic anemia. Recently, RTX has also been suggested for the treatment of certain connective tissue disease-related interstitial lung diseases (ILD) and hypersensitivity pneumonitis. Rare but serious pulmonary adverse reactions are reported. To raise awareness about this serious side effect of RTX treatment, as the indication for its use increases with time, we report five cases of probable RTX-ILD and discuss the current literature on this potentially lethal association.
