Pleuropulmonary complications of systemic lupus erythematosus (SLE) occur in 50-70% of patients and include pleuritis, pleural effusions, acute lupus pneumonitis, diffuse interstitial lung disease, atelectasis, diaphragmatic dysfunction and bronchiolitis obliterans. Additionally, a syndrome of acute reversible hypoxemia has recently been documented. This seems to occur in patients hospitalized for exacerbations of SLE and may be due to pulmonary leukoaggregation. It has become clear that other groups of pulmonary complications may be specifically associated with the antiphospholipid antibodies, both in patients with SLE and in those suffering from the "primary" antiphospholipid syndrome. These include pulmonary embolism and infarction, both thromboembolic and perhaps nonthromboembolic pulmonary hypertension, pulmonary arterial thrombosis, pulmonary microthrombosis, adult respiratory distress syndrome, intraalveolar pulmonary hemorrhage, as well as a postpartum syndrome.

Systemic lupus erythematosus (SLE) is the most common of the connective tissue disorders and can involve virtually any organ in the body. It is associated with pleuropulmonary manifestations in well over 50% of cases. Pleuritis with or without pleural effusion is the most common manifestation and can be particularly troublesome to manage but is rarely life-threatening. More serious manifestations in the lung include acute lupus pneumonitis with or without alveolar haemorrhage, chronic lupus pneumonitis and pulmonary hypertension. These all contribute significantly to overall mortality in SLE. The association between SLE and the antiphospholipid syndrome, leading to venous thrombosis and pulmonary embolism, is well recognized. Up to 20% of all cases of SLE present in childhood and many of these have pulmonary features at presentation or during the course of their illness. Sepsis is one of the main causes of death in SLE and pulmonary sepsis in these often immunocompromised patients contributes a significant proportion. Several drugs can produce a clinical syndrome that has many of the clinical and immunological features of SLE. Pleuritis may be seen in up to half of these cases of drug induced SLE. The development of SLE and conditions such as sarcoidosis or asbestosis in the same patient may represent a simple coincidence but there is some evidence for a closer association between these disorders.

Antiphospholipid syndrome is characterized by recurrent fetal loss, arterial and venous thromboses, thrombocytopenia and circulating antiphospholipid antibodies. Few patients have a rapidly progressive, fatal outcome. We report two young patients with systemic lupus erythematosus and antiphospholipid antibodies who died after a short course of disease. Although clinical and laboratory findings differed in both patients--small vessel thromboses and microangiopathic hemolytic anemia mimicking thrombotic thrombocytopenic purpura predominated in one of the patients while small and medium size vessel thromboses without hemolysis were present in the other case--autopsy revealed widespread visceral thromboses in both of them, features consistent with a diagnosis of catastrophic antiphospholipid syndrome. This syndrome has not been reported to occur in association with Pneumocistis carinii pneumonia as we describe in one of our patients.

We report a case of acute adrenal insufficiency in a context of probable bilateral adrenal haemorrhage, as revealed by CT-scan in a 52-year-old woman with a history of spontaneous abortion and repeated ischaemic stroke without symptoms or signs of collagen vascular disease. The symptoms began after the patient had successfully been treated for pneumonia. She had persistently high titres of IgG anticardiolipin antibodies, antibodies against beta 2-glycoprotein I and a lupus anticoagulant. The diagnosis of primary antiphospholipid syndrome with adrenal insufficiency was postulated.

We present a case of multiple organ dysfunction syndrome with acute respiratory failure due to alveolar haemorrhage associated with antiphospholipid antibodies in a 42-year-old woman with a medical history of antinuclear antibody-negative systemic lupus erythematosus and antiphospholipid syndrome. Severe respiratory failure, circulatory shock and acute renal failure necessitated artificial ventilation, inotropic and vasopressor therapy, and continuous venovenous haemofiltration. A tentative diagnosis of haemorrhagic lupus pneumonitis or pulmonary manifestation of antiphospholipid syndrome was made. Lupus anticoagulant, IgG anticardiolipin and anti-beta2-glycoprotein I antibodies were positive. High-dose glucocorticoid, anticoagulation with heparin, plasmapheresis and cyclophosphamide improved her clinical condition. Despite this, the patient died several days later of spontaneous intracranial haemorrhage. This case illustrates the uncommon manifestation of acute respiratory failure associated with antiphospholipid syndrome.

The association between systemic lupus erythematosus and antiphospholipid syndrome can cause several complications. We report a 45 years old woman, treated with steroids for a systemic lupus erythematosus. She presented with a clinical picture of a lupus pneumonitis and, subsequently, with the picture of a pulmonary thromboembolism. The diagnosis was confirmed by helicoidal computed axial tomography. The patient was treated with anticoagulants, with a favourable outcome.

Dermatomyositis and antiphospholipid syndrome are rare diseases that can be associated pulmonary damage. We report a case of anti-phospholipid syndrome that presented with bilateral pulmonary embolism and subsequently developed pulmonary infiltrates in association with the characteristic muscular and cutaneous features of dermatomyositis. Histological examination of trans-bronchial biopsies revealed bronchiolitis obliterans organizing pneumonia.

Rheumatological conditions can sometimes present as emergencies. These can occur due to the disease process or may be iatrogenic. Some of the important articular emergencies are septic arthritis, acute polyarthritis and atlanto-axial dislocation. Classical polyarteritis nodosa may present with massive gastro-intestinal bleeding, intestinal perforation or acute pancreatitis. Adult respiratory distress syndrome, bilateral pneumonitis and diffuse alveolar haemorrhage due to systemic lupus erythematosus or systemic necrotising vasculitis and ventilatory failure due to polymyositis are some of the respiratory emergencies. Scleroderma is well known to cause renal crisis which can be fatal if not diagnosed and managed promptly. Microscopic polyangiitis and Wegener's granulomatosis may cause rapidly progressive renal failure. Cerebrovascular accident, cortical vein thrombosis, seizures and acute psychosis are important neurological complications of rheumatic disease. Cardiac emergencies include tamponade, acute myocarditis and acute myocardial infarction. Vision can be threatened in Behcet's disease, temporal arteritis and seronegative spondylarthritis. Catastrophic antiphospholipid syndrome is a devastating emergency. The management of above emergencies includes critical care, immunosuppression when indicated and withdrawal of the offending drug. Anticoagulants have to be used in the management of antiphospholipid syndrome. A good understanding of these conditions is of paramount importance for proper management.

We describe the case of a 70-year-old male with the catastrophic antiphospholipid syndrome admitted for skin gangrene of the fingers. The initial diagnosis was antiphospholipid antibody syndrome in a patient with rheumatoid arthritis and a history of deep vein thrombosis of the lower limbs. Liver involvement, the characteristic skin gangrene, pneumonia and worsening severe renal failure were determinant to make the final diagnosis of catastrophic antiphospholipid syndrome that led the patient to death.

Pulmonary capillaritis and alveolar hemorrhage are rare yet serious and life threatening complications of systemic lupus erythematosus (SLE). Pulmonary manifestations of antiphospholipid syndrome (APS) are similar and include, apart from pulmonary embolism and pulmonary hypertension, pulmonary capillaritis, diffuse alveolar hemorrhage and respiratory insufficiency in patients with catastrophic APS. Herein, we described the radiological features of three patients with pulmonary and SLE-associated APS, manifested with pulmonary edema, capillaritis and alveolar hemorrhage. We observed that the radiological features of pulmonary APS shared close resemblance to those of pulmonary SLE. Based on these findings, we conclude that both entities are not only histologically, but also radiologically indistinguishable from each other, suggesting a mutual pathogenetic mechanism. This raises the question of whether some of the reported lupus pneumonitis cases in the past might be manifestations of APS rather than of SLE.
