Three patients with Munchausen's syndrome were seen with symptoms suggesting serious pulmonary disease. One patient, a student respiratory therapist, simulated respiratory failure which resulted in a tracheostomy and prolonged ventilator support. The second, a licensed practical nurse, feigned a lupus erythematosis syndrome, with alarming, simulated hemoptysis produced by slashing the posterior tongue with a razor blade. The third patient, a nurse, underwent exhaustive testing at three hospitals for profuse "hemoptysis" until she admitted she obtained the blood from her arm by venesection.

Pulmonary hemorrhage may occur in patients with immune-mediated glomerulonephritis. This association can be seen in a variety of disorders including systemic lupus erythematosus, vasculitis, Wegener's granulomatosis, anaphylactoid purpura and Goodpasture's syndrome. Immune mechanisms, such as immune complexes and/or autoantibodies, play a role in the pathogenesis of pulmonary and glomerular injury. Acute pulmonary hemorrhage can lead to respiratory failure and has a high mortality. Therapy with immunosuppressive agents such as pulse methylprednisolone and cyclophosphamide will control the hemorrhage and improve pulmonary function in most cases.

Pulmonary hemorrhage due to small vessel vasculitis is a well recognized complication of many autoimmune and collagen vascular disorders. The antiphospholipid antibody syndrome (APS) is a disorder associated with hypercoagulability, thrombocytopenia, and thromboembolic phenomena. Pulmonary manifestations include pulmonary embolism, pulmonary hypertension, and respiratory failure associated with diffuse pulmonary infiltrates. We describe a patient with the APS syndrome, without systemic lupus erythematosus, who developed pulmonary hemorrhage due to pulmonary capillaritis with evidence of perivascular immune complex deposition.

Over the past 50 years, survival has improved in patients with systemic lupus erythematosus and associated nephritis. Yet, there are few long-term outcome studies in patients with well-defined nephropathy. We examined the outcome of 439 patients with lupus nephritis who were seen at the Mayo Clinic between 1964 and 1986 in whom renal biopsies were assessed using the World Health Organization (WHO) classification. There were 341 women and 98 men (mean +/- s.d., age 33.5 +/- 14 years); 200 (46%) patients were hypertensive and 249 (57%) had impaired renal function at renal biopsy. All WHO morphologic classes were represented and 339 (77%) patients had class III, IV and V (the more severe forms of nephritis). Follow-up averaged 10.2 years per patient. At last contact, 286 (65%) patients were alive and 153 (35%) were dead. Overall patient survival was 80%, 69% and 53% at 5, 10 and 20 years after biopsy that was significantly worse than expected survival (P < 0.001). Ten-year cumulative patient survival improved comparing earlier to more recent time spans: 64% in 231 patients seen during 1964-75; 76% in 2089 patients studied during 1976-86 (P = 0.03). Survival free of renal failure was 83%, 74% and 64% at 5, 10 and 20 years, and survival was unfavorably influenced by progressive WHO class, hypertension, impaired renal function, nephrotic range proteinuria, hypoalbuminemia and anemia. Multivariate analysis found impaired renal function, increased urine protein, anemia and younger age to be independent predictors of renal failure. WHO class was not a significant predictor when adjusted for these four factors. Cardiovascular events accounted for 48% of the known deaths and were equally distributed across all WHO classes, followed by infections, renal failure, malignancy, respiratory failure and gastrointestinal bleeding.(ABSTRACT TRUNCATED AT 250 WORDS)

We experienced three patients who have collagen diseases with respiratory failure accompanied by hyponatremia. They were one systemic lupus erythematosus patient with interstitial pneumonia, one rheumatoid arthritis patient with acute pneumonitis, and one dermatomyositis patient with pulmonary fibrosis and organizing pneumonia. In all 3 patients, hyponatremia appeared along with a decrease in arterial O2 partial pressure (PaO2) and the hyponatremia tended to improve when the PaO2 increased after inhalation of oxygen, even though their respiratory failure were not improved. In dermatomyositis patient, serum Na levels were over-corrected after increase in PaO2. The serum and urine osmolality, serum antidiuretic hormone (ADH) levels and clinical pictures demonstrated a presence of inappropriate secretion of ADH (SIADH) in all 3 cases when hyponatremia and hypoxia appeared. A close association between hyponatremia and hypoxia observed in 3 patients strongly suggested that their SIADH were associated with hypoxia since SIADH could be demonstrated by hypoxia. Therefore, it is important to realize that hypoxia-induced hyponatremia will be promptly corrected to hypernatremia by an oxygen inhalation, which could cause a lethal central pontine myelinolysis.

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.

Non-resolved chronic pulmonary thromboembolism is a frequent cause of pulmonary hypertension. In long-standing disease hypertension is progressive due to intimal and medial changes in the perfused vessels. Non-resolution of thromboemboli is often associated with underlying coagulopathies; the presence of a lupus anticoagulant may pose a significant problem in the peri-operative management of these patients. Pulmonary thrombendarterectomy presents an efficient option of treatment which is feasible in the majority of patients. By means of pulmonary angiography and computed tomography operability is verified by the often difficult recognition of thromboembolic changes in the central pulmonary arteries. Patients with solely peripheral thromboembolic changes or primary pulmonary hypertension must be excluded. In presence of significant exertional dyspnea and/or pulmonary pressure elevation surgery is indicated. Mortality is high and mainly related to unrelieved pulmonary hypertension or pulmonary complications; pulmonary reperfusion edema, respiratory failure or pneumonia and sepsis. In all survivors the reduction of pulmonary hypertension is highly significant and persistent. Thromboembolic pulmonary hypertension may be treated curatively in most patients by thrombendarterectomy. Correct selection of surgical candidates is mandatory, and the patients should preferably be diagnosed and undergo surgery in an early stage of their disease.

A 26-year-old woman with systemic lupus erythematosus (SLE) developed dyspnea and hypoxemia on exertion. She died from rapidly progressive respiratory failure. Autopsy revealed right ventricular hypertrophy and occlusion of the pulmonary veins compatible with pulmonary venoocclusive disease (PVOD). Although PVOD has been reported in patients with suspected collagen vascular disease, this appears to be the first reported case of PVOD occurring in a patient with SLE.

A case of mixed connective tissue disease (MCTD) in a female with positive ribonucleoprotein antibody and overlapped manifestations of systemic lupus erythematosus and dermatomyositis is presented. During the last 9 years of her 13 year clinical course, she repeatedly manifested abdominal distension, pneumoperitoneum and malabsorption syndrome. She died, aged 54 years, of respiratory failure secondary to pulmonary compression from marked abdominal distention. Autopsy revealed esophageal fibrosis with ulceration and the typical appearance of pneumatosis cystoides intestinalis (PCI), in association with atrophy and fibrosis of the inner circular muscle layer of the small bowel. The association of PCI with MCTD is reviewed briefly.

Interstitial lung disease is a significant prognostic factor in connective tissue diseases. To further clarify clinical and immunological features of interstitial lung disease, we studied 894 consecutive patients with connective tissue diseases first evaluated between 1970 and 1993. Interstitial lung disease was found in 101 of 181 (56%) patients with systemic sclerosis, 92 of 183 (50%) with overlap syndrome, 35 of 76 (46%) with polymyositis/dermatomyositis, and 13 of 444 (3%) with systemic lupus erythematosus (p < 0.05, systemic lupus erythematosus vs. other connective tissue diseases). The presence of interstitial lung disease correlated with decreased survival in systemic sclerosis and in polymyositis/dermatomyositis, but not in overlap syndrome or in systemic lupus erythematosus. Interstitial lung disease in patients with connective tissue diseases was classified into two types: acute (n = 8) and chronic (n = 233). Among the 8 patients with acute disease, 4 (all with dermatomyositis) died of respiratory failure and 3 (all with systemic lupus erythematosus) responded to corticosteroids. Among the 233 patients with chronic interstitial lung disease, 20 had polymyositis/dermatomyositis with anti-aminoacyl tRNA synthetase antibodies and 40 had overlap syndrome with anti-U1 RNP antibodies. Respiratory failure in these patients was not frequent and occurred late in the course of the disease. As a cause of death, respiratory failure was associated with autoantibodies to topoisomerase I and aminoacyl tRNA synthetase but not anti-U1 RNP. Autoantibodies to aminoacyl tRNA synthetases were detected before the development of interstitial lung disease in 9 patients with polymyositis/dermatomyositis. We conclude that the clinical features of interstitial lung disease associated with connective tissue diseases vary with the type of connective tissue disease, and that analysis of autoantibodies can be useful in establishing a diagnosis and in forecasting the course and outcome.
