This review is focused on the roles of laboratory test in acute renal failure (ARF). The roles of the laboratory test changes along with the alterations in clinical features and with the advances of treatment. Recent acute renal failure is characterized by the following three features: most of the ARF develops in hospitals, the frequency of nonoliguric ARF is increasing, and the association of other organ failure such as heart failure, liver failure or respiratory failure, increases the mortality rate. Hemodialysis is instituted in the early phase of ARF to enable the supply of enough nutriments and drugs. These features of recent ARF increases the importance of the frequent analysis of plasma creatinine in patients, who are at risk for ARF, to diagnose ARF at the onset. After the development of ARF, laboratory tests for the evaluation of other organ function is repeated. The development of new drugs increases the incidence of interstitial nephritis, and the advances in the therapeutic approach on systemic diseases (such as SLE or PN), which frequently develop ARF, alter the prognosis of these diseases. Since the early diagnosis of these diseases is important, it is necessary to develop noninvasive and reliable tests for the diagnosis of these diseases.

A 60-year-old female was admitted to our hospital because of respiratory failure. She was diagnosed as having systemic lupus erythematosus (SLE) in 1971 and had been treated with low-dose oral corticosteroids for 13 years. She developed cough, fever and anemia several days after oral corticosteroids were tapered. Initially, she had no complications such as congestive heart failure, renal failure or bleeding tendency. Respiratory failure progressed without any response to antibiotic therapy. Chest roentgenogram showed bilateral diffuse infiltrates and air bronchograms. There was no improvement even with steroid pulse therapy, and she died of multiple organ failure. Autopsy revealed massive intra-alveolar hemorrhage and interstitial pneumonitis. Deposition of immunoglobulins in the lung was not seen. To our knowledge, this is the 11th reported case of SLE associated with pulmonary hemorrhage in Japan.

The association of pneumothorax and mediastinal emphysema in systemic lupus erythematosus (SLE) has not been described extensively in the literature. We describe a 36 year-old man with SLE, complicated by bilateral pneumothorax, mediastinal emphysema and pneumoperitoneum. Despite the treatment received, he died of respiratory failure.

During a period of 10 years 129 immunosuppressed HIV-negative patients were evaluated for pulmonary complications. A definite diagnosis could be established in 72 cases (56%): Pneumocystis carinii pneumonia (PCP) (25), pulmonary involvement of underlying disease (10), drug toxicity (8), mycobacterioses (6), bacterial pneumonias (5), aspergillosis (5), others (13). The underlying conditions in patients with PCP were: lymphatic neoplasias (11), immunosuppression after solid organ (9) and after bone marrow transplantation (3), cytotoxic therapy for lupus erythematodes (1) and carcinoma (1). In 8 of 9 transplant patients anti-rejection therapy preceded the episode of PCP. Six patients (24%) died from respiratory failure 1 to 25 days after diagnosis of PCP, despite mechanical ventilation in four. Two patients recovered completely after mechanical ventilation for 14 and 30 days respectively. The frequency of PCP has markedly increased during the last few years: 1981-1987: 2 cases (6%), 1988: 4 (14%), 1989: 8 (42%) and 1990: 11 (26%). This can hardly be explained by improved diagnostic sensitivity or an increased number of immunosuppressed patients. Apart from the use of more potent immunosuppressive agents, the increased prevalence of Pneumocystis carinii may play an important role.

Lung function was prospectively studied in a group of non-selected systemic lupus erythematosus (SLE) female patients who consecutively came to our Lung Function Laboratory. There was no previous history of smoking in any patient nor there was clinical and/or radiographic evidence of lung affectation prior to the diagnosis of SLE. Some respiratory lung function abnormalities were observed in 17 patients (65%). The most frequent functional anomaly was the alteration in carbon monoxide transfer (DLCO), which was present in 10 cases (38%). On the other hand, a restrictive ventilatory failure was observed in 8 patients (31%) and a obstructive ventilatory failure in 6 other (23%). Out of these, 3 patients (12% of the total number of cases) presented bronchial hyperreactivity, which could also be confirmed in a patient presenting a mixed ventilatory failure. Isolated air entrapment could be observed in 2 patients, which could indicate disfunction of small airways in these cases. There was no correlation between functional respiratory failure and clinical activity of SLE, duration of the disease, other organ involvement, treatment and/or serum antibodies. Given that a great number of these functional lung anomalies (42%) exist in the absence of any clinical and radiological anomalies and that an important subgroup of patients are responsive to bronchodilators, we consider that the systemic evaluation of lung function must be obliged in the clinical treatment of SLE patients.

A 37-year-old man with acute myeloblastic leukemia (FAB M2) in first remission underwent a bone marrow transplant (BMT) following conditioning with high-dose cytarabine and total body irradiation. The donor was an HLA-identical brother. Graft rejection occurred and a second BMT was performed from the same donor following conditioning with cyclophosphamide. Engraftment was achieved, but the patient developed severe jaundice and died of respiratory failure on day +46 after the second BMT. Liver biopsy revealed luminal narrowing of the central veins and a diagnosis of hepatic veno-occlusive disease (VOD) was made. The coagulation studies showed a prolonged kaolin clotting time which was not corrected by 1:1 mixture with normal plasma, and the platelet neutralization test was positive. Dilute tissue thromboplastin time and dilute Russell viper venom time were also prolonged. These results fulfilled the criteria for lupus anticoagulant, which may have contributed to VOD in this patient.

Neither pneumothorax or mediastinal emphysema are well recognized pulmonary manifestations of systemic lupus erythematosus (SLE). We describe a 41-year-old woman with severe lupus pneumonitis complicated by recurrent pneumothoraces and mediastinal emphysema. Other features of SLE were minimal. She died of progressive respiratory failure. Autopsy revealed innumerable blebs in both lungs responsible for the pneumothoraces and mediastinal emphysema. Both pneumothoraces and mediastinal emphysema occurred during a course of corticosteroid therapy. The course of her illness was unaffected by treatments that included high dose corticosteroids, immunosuppressives and plasmapheresis. Better medical treatment for these lupus complications should be sought in addition to surgery.

We report the case of a patient with myotonic dystrophy who developed tachypnea and severe dyspnea without respiratory failure. Myotonia of inspiratory muscles was diagnosed on the grounds of marked prolongation of transdiaphragmatic pressure (Pdi) decay during sniffs. In view of the recognized sensory role of inspiratory muscles in dyspnea, it was hypothesized that antimyotonic therapy might relieve dyspnea in this patient. Procainamide therapy induced a decrease in half relaxation time of Pdi during sniffs and yielded a striking clinical improvement with cessation of tachypnea and dyspnea. Later, this beneficial effect was maintained by tocainide after procainamide was stopped because of a lupus syndrome. We conclude that myotonia of respiratory muscles can cause severe dyspnea that can be improved by antimyotonic therapy.

A 53 year old Chinese man with systemic lupus erythematosus (SLE) had an isolated 12th nerve palsy and acute pneumonitis. He died of respiratory failure despite intensive treatment. A limited necropsy was performed, and amyloid deposits were identified in both lung and kidney tissue. This case is highly unusual because (a) to our knowledge an isolated hypoglossal nerve palsy associated with active SLE has never been reported; (b) only one of nine reported cases of amyloidosis in patients with SLE had amyloid deposits in the lung.

We have reviewed the alveolar hemorrhage (AH) syndromes, defined as immune or idiopathic disorders associated with diffuse microvascular hemorrhage into the acinar portion of the lung. The disorders that are most often associated with AH include antibasement membrane antibodies (ABMA) disease, idiopathic pulmonary hemosiderosis, systemic lupus erythematosus, systemic vasculitides, and idiopathic rapidly progressive glomerulonephritis. An approach to the recognition, diagnosis, and treatment of the AH syndromes has been outlined and several illustrative case studies have been presented. Recognition of AH is not usually difficult, but does require a high index of suspicion, since many disease processes may give rise to hemoptysis with infiltrates on chest roentgenogram. Recognition of AH is aided by careful clinical and laboratory assessment for evidence of extrapulmonary disease; simple hematologic studies such as sequential hemoglobins and iron studies; and measurement of carbon monoxide uptake by the lungs. Early recognition of AH may decrease the likelihood of respiratory failure and end-stage renal disease. The specific etiology of AH is usually determined by clinical examination, serologic assay for ABMA, and percutaneous renal biopsy by immunofluorescence. Open-lung biopsy is required in a minority of cases. High-dose pulse methylprednisolone appears to effectively control AH of diverse etiology. Combined plasma exchange and immunosuppression controls AH in ABMA disease and is the treatment of choice in this disorder. Cyclophosphamide is used for Wegener's granulomatosis, and sometimes in systemic necrotizing vasculitis, in an attempt to prevent irreversible damage to the kidneys.
