A 69-year-old man was admitted with general fatigue, dyspnea, cough, fever and right pulmonary infiltrations on a chest X-ray films. He had suffered from myocardial infarction 8 years before. Since September 1987, he had been given Aprindine in addition to previous drugs. In early November 1987, he developed dyspnea. Antibiotics were not effective. He was hospitalized on Nov. 13, '87 when crepitations were audible on his right chest. Methylprednisolone pulse therapy was effective, however right pneumothorax developed. He underwent right thoracotomy and lung biopsy. Lung biopsy specimens showed pathological features of bronchiolitis obliterans organizing pneumonia (BOOP). Corticosteroid therapy yielded a remarkable clinical, physiological and roentgenographic recovery. However, approximately two years later during prednisolone maintenance therapy, BOOP recurred. He responded again to corticosteroid treatment, however he died of hepatic failure on Dec. 17, '89. "Idiopathic" rather than "drug induced" was suggested for the cause of BOOP in this case.

A twenty six year old homosexual male with the diseases Hepatitis B, Lues, Gonorrhoea, ascending myelitis, lymphadenitis got additionally a chronic-inflammatory bowel disease, which first was discussed as Crohn's disease. Two "attacks" were "successfully" treated with Methylprednisolone. The patient died twelve month later in the follow of a pneumocystitis carinii pneumonia. The cause of the symptoms of the chronic-inflammatory bowel disease was a cytomegalovirus infection with acquired immune deficiency-syndrome.

We explored the protective effect of corticosteroids on the mortality of mice that received thoracic irradiation. Methylprednisolone, 100 mg/kg/week, given from 11 weeks after gamma irradiation of the thorax resulted in an increase in the LD50 (11-26 weeks) from 14.3 +/- 0.3 (mean +/- SE) Gy to 17.6 +/- 0.4 Gy, P less than 0.001, a protection factor of 1.2. Withdrawal of steroids at various times during the period of radiation pneumonitis resulted in accelerated mortality in the next 2-4 weeks, so that the cumulative mortality "caught up" with that of control animals by 4 weeks after steroid withdrawal. However, after the end of the usual period of pneumonitis withdrawal of steroids did not result in accelerated mortality, suggesting that the time when steroids are protective corresponds to the duration of pneumonitis. A smaller dose of steroids, 25 mg/kg/week, was found to be as protective as the larger dose used in the above experiments. The possibility that corticosteroids reduce mortality, even when given many weeks after radiation, may have important practical and theoretical implications.

To evaluate the role of corticosteroids as treatment for acute exacerbations of chronic obstructive pulmonary disease, we conducted a double-blind, randomized, placebo-controlled trial in 44 consecutive patients with chronic bronchitis and severe airflow obstruction. All were hospitalized with acute respiratory insufficiency from acute bronchitis. Patients with asthma, atopy, or pneumonia were excluded. Treatment consisted of intravenous aminophylline, inhaled isoproterenol, antibiotics, and either methylprednisolone, 0.5 mg/kg of body weight, or placebo every 6 h intravenously for 72 h. Bedside spirometry was done before and after bronchodilator inhalation three times daily. The methylprednisolone-treated group had a greater improvement in both prebronchodilator and postbronchodilator forced expiratory volume in 1 second (P less than 0.001). More patients with large improvements in their prebronchodilator or postbronchodilator flow rates, or both (greater than or equal to 40% by 72 h), received methylprednisolone (P less than 0.01). Methylprednisolone improved airflow more than placebo when added to standard therapy in patients with chronic bronchitis and acute respiratory insufficiency.

This is a rare case of Dyskeratosis Congenita (DC) with acute interstitial pneumonia. A 51-year-old man with DC was admitted to our hospital because of cough, sputum and fever. Chest X-ray film showed ground glass opacities in all lung fields for a while steroid's therapy proved effective, but about seven months later the patient's condition became serious. Methylprednisolone, cyclophosphamide and mechanical ventilation therapy were not effective. He died and an autopsy was performed. The lung specimen showed Organizing Diffuse Alveolar Damage, and some parts pointed to bacterial infection. But Pneumocystic carinii pneumonia and Fungal infections were not found. It is therefore necessary to conduct intensive examinations of lung involvement of patients with Dyskeratosis Congenita.

Traumatic spinal cord injury is frequently associated with brain injury and with alterations in respiratory and cardiovascular function that require critical care management. Complications include respiratory failure, atelectasis, pneumonia, neurogenic shock, autonomic dysreflexia, venous thromboembolism, and sepsis. While complications may be managed with supportive care, the goal of ameliorating neurologic outcome has proved elusive. Methylprednisolone, when instituted <8 hours after traumatic spinal cord injury, was associated in two clinical trials with statistically significant improvements in motor scores at 6 months and 1 year; however, critical reappraisal of these data raises questions about their validity and clinical relevance. Until more evidence of clinically effective therapies is available, acute management must be driven by pathophysiologic principles, with emphasis on interventions that attenuate secondary neurologic injury; these include the rational use of immobilization, cautious airway management, and promotion of cord perfusion and oxygenation with the appropriate level of hemodynamic and respiratory support. Clinical trials of pharmacologic neuroprotection have yielded disappointing results, but the ongoing elucidation of spinal cord repair and regenerative mechanisms suggests new therapeutic prospects.

Bronchiolitis obliterans organizing pneumonia (BOOP) has been described after bone marrow, lung, heart-lung, and renal transplantation, but rarely after orthotopic liver transplantation (OLT). We report a case of BOOP after OLT to emphasize BOOP as an under diagnosed and treatable cause of nonresolving pneumonia, which may not be preventable by maintenance low-dose prednisone. A 48-year-old man was hospitalized for dyspnea and cough one month after OLT. Among his medications were tacrolimus and prednisone. Physical examination was significant for lung crepitations and bilateral leg edema. Chest x-ray revealed bilateral infiltrates. Computed tomography (CT) of the chest demonstrated bilateral diffuse infiltrates with areas of sparing and nodularities. Bronchoscopy was normal and bronchoalveolar lavage was negative. Lung biopsy was performed and demonstrated serpiginous plugs of fibroblastic tissue filling the alveolar spaces, focal fibrosis of some alveolar septa, and reactive pneumocytic hyperplasia consistent with BOOP. Methylprednisolone was continued with clinical improvement and weaning from the ventilator, but subsequent sepsis and multisystem organ failure finally led to the patient's death.

Pneumonia and acute respiratory distress syndrome are life-threatening complications after pneumonectomy carrying high mortality. Because pulmonary reserve is inadequately low, an effective therapeutic strategy is needed to treat hypoxia. Extracorporeal membrane oxygenation is a highly effective method to reverse hypoxia in patients with acute respiratory distress syndrome, but has only once been described in a patient with postpneumonectomy pulmonary edema. We report a case of successful extracorporeal membrane oxygenation therapy in a patient with pneumonia-associated acute respiratory distress syndrome after pneumonectomy. Methylprednisolone therapy caused a dramatic improvement of pulmonary and systemic organ function.

Acute postinfectious glomerulonephritis (APIGN) is usually diagnosed in young people, while in elderly people rapidly progressive forms appear to be the most important glomerular disease causing acute renal failure. We report on a 85-year-old woman with acute renal failure due to APIGN. An 85-year-old woman with a history of hypertension and cerebrovascular disease was hospitalized because of diarrhea and syncope associated with atrial fibrillation. She was found to have left lower lobe pneumonia. Serum creatinine was over 2 mg/dL. Fluids were given, without improvement in renal function but leading to volume overload instead. Within a few days serum creatinine reached a level of 5.4 mg/dL with reduction of urine output despite administration of diuretics. The patient developed hematuria and purpura of the feet. Serum IgA was high and the urine sediment showed casts. Methylprednisolone 125 mg i.v. was given for three days followed by prednisone 50 mg daily. The patient's clinical condition gradually improved and serum creatinine decreased to 1.9 mg/dL. Renal biopsy showed APIGN. During hospitalization, three major complications occurred: hemodynamic instability due to atrial fibrillation, Clostridium difficile colitis and urinary tract infections due to Enterococcus faecalis and Candida tropicans, all successfully treated. APIGN should be taken into account as a cause of acute renal failure in hospitalized elderly patients with many comorbidities.

A 45-year-old man with acute myelogenous leukemia (WHO classification, AML with multilineage dysplasia) received allogeneic bone marrow transplantation from an HLA-identical brother in first remission. He became febrile on day 7, and pulmonary failure and multi-organ failure developed subsequently, requiring mechanical ventilation. Chest X-ray and CT scan demonstrated diffuse interstitial shadows, suggesting the development of idiopathic pneumonia syndrome. Administration of methylprednisolone and tacrolimus was effective, but respiratory failure exacerbated along with a decrease in the dose of steroids. Lung biopsy revealed organizing pneumonia with CMV pneumonia. Methylprednisolone and mycophenolate mofetil were instituted, which led to an improvement of lung injury. Intensive immunosuppressive therapy with mechanical ventilation should be considered for the treatment of idiopathic pneumonia syndrome after allogeneic bone marrow transplantation.
