Pulmonary hypertension is one of the complications in the pulmonary manifestation of SLE. Following a two year SLE history a patient developed pulmonary hypertension although his chest radiograph showed neither pulmonary changes nor signs of hypertension. In two other patients, interstitial fibrosis, pleurisy and pulmonary hypertension were the initial manifestations of SLE. They all complained of dyspnoea and respiratory chest pain. Lung function studies showed restrictive changes, reduced lung compliance and, by two patients, reduced diffusion capacity. Lung biopsy performed in one patient revealed interstitial fibrosis, focal lymphocyte infiltrations and intima proliferation of the arterioles. All three patients were treated with anticoagulants in addition to steroids and cytotoxic drugs. After a period of 8 to 42 months examinations were repeated and all three patients showed improved hypertension and less physical ailment. The radiographs from two patients even revealed an improvement of their pulmonary changes.

Systemic lupus erythematosus, polymyositis/dermatomyositis, connective tissue disease, and polyarteritis nodosa are the collagen vascular diseases (CVDs) most likely to mimic pneumonia. All can be associated with an acute illness characterized by fever, cough, dyspnea, pleural symptoms, and an abnormal chest roentgenogram. Recognition of the CVD-associated pulmonary process requires sophisticated serological testing and chemical pleural fluid analysis coupled with the exclusion of pulmonary infection and pulmonary embolization. This review emphasizes the clinical characteristics of these CVDs, the diagnostic tests most helpful in recognizing them, and the differential diagnosis of pleuroparenchymal disorders that occur in these patients.

The coexistence of systemic lupus erythematosus (SLE) and thymoma is rare. We describe 2 female patients with this combination. A 48-year-old woman presented with dyspnea due to a left pleural effusion. Her past history revealed over the previous 3 years the development of anemia, thrombocytopenia, alopecia, pericardial effusion and proteinuria. Four months prior to this hospitalization, the patient was first admitted due to purpura. At that time, laboratory tests revealed an elevated sedimentation rate, elevated titers of ANA and anti-DNA. Chest X-ray demonstrated a widened mediastinum, and upon operation an encapsulated thymoma was excised. Four months following the thymectomy, the patient is unresponsive despite high dose steroid therapy. Another patient, a 30-year-old woman, presented with SLE (cutaneous, arthritis, anemia, positive ANA and high titers of anti-DNA) and thymoma simultaneously. Six years after thymectomy the patient is in SLE remission. Thymectomy in mice prone to autoimmunity (NZB/W mice) has been shown to accelerate the autoimmune manifestations. Conversely, the opposite effect is seen in MRL/lpr mice. The immunological effect of adult thymectomy on the course of human SLE remains to be established, on a larger series of patients. It seems that the heterogenicity of human patients is exemplified by the contrasting effects of thymectomy for thymoma in SLE patients.

Shrinking lung syndrome of systemic lupus erythematosus is characterized by dyspnea, diaphragmatic elevation with decreased mobility, and a restrictive defect. We report three cases in females with systemic lupus erythematosus aged 25, 29, and 42 years. Dyspnea and chest pain were present in all three patients. Elevation of the diaphragm was bilateral in two patients and unilateral in one. Two patients had a very severe restrictive defect. Onset of the pulmonary manifestations occurred in the absence of a flare of the connective tissue disease in two patients. Corticosteroid therapy consistently produced a clinical improvement with a decrease in the restrictive defect. Evidence suggesting diaphragmatic dysfunction is discussed.

There are two aspects to considerations of the value of peritoneal dialysis (PD) in the treatment of renal insufficiency with associated pathology. The first involves the effects of the treatment on the symptoms or evolution of the pathology. Examples include the improvement of dyspnea due to cardiac insufficiency (CI) and of cirrhotic ascites (CA). However, there is also an undefined risk of reactivation lupus. The second facet is the increased risk of peritoneal infection, particularly for patients who are HIV + or who are immunosuppressed due to lupus or myeloma. In certain types of case (lupus with intractable vascular thrombosis, intolerance of ultrafiltration in cases of CI, AC or generalised amyloidosis) PD has particular advantages. Nevertheless, there has been no appropriate prospective study to demonstrate or otherwise the advantages in terms of survival. The use of PD remains therefore a matter of choice for individual patients and experienced health care team.

A 63-yr-old woman with systemic lupus erythematosus (SLE) diagnosed 12 mo previously and treated with prednisolone and cyclophosphamide presented with recent fever and dyspnoea. The etiology of a 3 cm diameter centrally cystic coin lesion in the lower lobe of the left lung was obscure. Blood cultures and sputum examination had been non-contributory, and the diagnosis of Nocardia asteroides infection was initially made by cytologic examination of material obtained by lung fine-needle aspiration (FNA). It is notoriously difficult to detect this organism by conventional sputum examination or with histologic sections, and it has rarely been detected by lung FNA. If this organism is demonstrated, appropriate microbiologic cultures for confirmation and susceptibility testing should be instituted. Long-term antimicrobial therapy is needed. In this case, complete resolution of the lung lesion followed 5 mo of therapy.

The association of systemic lupus erythematosus (SLE) with amyloidosis is exceptional. We present a 37-year-old patient who was diagnosed five months earlier for SLE. She developed an acute episode of chest pain, cough and dyspnoea. Hypoxemia and obstructive changes in respiratory tests were present. The chest X-ray was repeatedly normal. Open lung biopsy revealed lupus pneumonitis with positive stain for immunoglobulins and complement, bronchiolitis obliterans, and pulmonary amyloidosis.

We identify and describe clinical findings in hypocomplementemic urticarial vasculitis syndrome (HUVS), an uncommon to rare illness related to systemic lupus erythematosus (SLE). A patient with recurrent, idiopathic urticaria-like lesions was diagnosed as having HUVS if a lesional biopsy showed leukocytoclastic vasculitis, the serum C1q was markedly decreased, and antibody to C1q was detected in the patient's serum. The clinical characteristics, serologic findings, and outcome of patients who met these criteria were determined from prospective and retrospective data, including hospital and office records, patient interviews, previously banked serum samples, and freshly drawn sera. Eighteen patients with HUVS were identified, and high incidences of angioedema, ocular inflammation, glomerulonephritis, and obstructive pulmonary disease were found. Renal and lung biopsies showed mesangial or membranoproliferative glomerulonephritis and severe pulmonary emphysema without vasculitis. Pulmonary function was measured in 17 patients, 11 of whom had dyspnea. All dyspneic patients had moderate to severe airflow obstruction, which progressed in all 11 and subsequently improved in only 1. Six of these 11 patients died of respiratory failure, 1 underwent lung transplantation, and 3 of the remaining 4 have moderately severe to life-threatening respiratory insufficiency. Treatment did not appear to alter the progression of obstructive lung disease. In contrast, renal insufficiency improved with treatment in 2 of 2 patients. Angioedema, ocular inflammation, obstructive lung disease, and glomerulonephritis appear to be common in HUVS, and lung disease causes substantial morbidity and mortality. The pathogenesis of HUVS may involve humoral autoimmunity, although it is not clear how autoimmunity would participate in development of obstructive lung disease. Cigarette smoking appears to be a risk factor for fatal lung disease in HUVS. All patients with HUVS should be made aware of this possibility and should be advised, encouraged, and helped to avoid tobacco smoke.

A 60-year-old stonemason, suffering for many years from joint pains and exertional dyspnoea, developed a high fever with weight loss. Physical examination revealed reddening of light-exposed skin areas, fine rales and overly warm and reddened hand and knee joints. Abnormal laboratory findings were increased erythrocyte sedimentation rate of 66 mm/h, C-reactive protein concentration of 1 mg/dl, haemoglobin of 9.4 g/dl and white cell count of 3300/microliters. Urine contained albumin (100 mg/dl) and cylinders. Titres of both antinuclear and anti-ds-DNA antibodies were elevated (1:2560 and > 97 U/ml, respectively). The chest radiography showed enlarged hili, as well as reticular and nodular shadows which histologically showed silicosis. Systemic lupus erythematodes was diagnosed and the patient was treated with prednisone (2 mg/kg daily), the dosage being reduced to 12 mg daily within 3 months. When the joint pains recurred, azathioprine (50 mg daily) was added for 24 months. At present he is receiving prednisone (12 mg daily) and there has been no recurrence for 4 years.

A 54 year-old woman who had a 6 month history of polyarthralgias, oral ulcers, weight loss and fatigue was admitted to the Urawa Municipal Hospital. She developed high fever, dyspnea and thrombocytopenia. Chest radiograph revealed massive right pleural effusion. At this time, laboratory investigations gave the following results: hemoglobin 12.7 g/dl, WBC 7700/microliters and platelet count 9.2 x 10(4)/microliters. Antibody to DNA was negative. Antinuclear antibody was positive at a titer of 320x in a centromere pattern; Anti-RNP and anti-Sm antibodies were negative. CH50 was 18.6 u/ml. C3 was 42.9 mg/dl. C4 was 11.5 mg/dl. Circulating immune complex (Clq) was 30.5 micrograms/ml. Circulating lupus anti-coagulant and anticardiolipine antibodies were positive. Thoracocentesis was performed; the material was a straw-colored exudate with over two thousands white cell per ul and showed marked reduction of complement titiers and elevated immune complex levels. She was then diagnosis as having SLE. Two weeks after admission, progressive leukopenia and anemia succeedingly occurred and resulted in severe pancytopenia. Bone marrow biopsy demonstrated marked marrow fibrosis and increased reticulin content with no evidence of malignancy. Steroid pulse therapy for 3 days started, and subsequently she was treated with 60 mg/day of prednisolone. Three weeks after starting on steroids, the massive pleural effusion was completely disappeared and complement titiers were normalized. Circulating immune complex has not been detected any more. After 8 weeks, the peripheral blood count was normalized. The dose of prednisolone was reduced progressively. On this occasion, the biopsy showed normocullular marrow with a marked reduction in the amount of reticulin.(ABSTRACT TRUNCATED AT 250 WORDS)
