24 subjects with chronic obstructive pulmonary disease were investigated in the course of acute respiratory failure defined by hypoxaemia, hypercapnia and respiratory acidosis. Haemodynamic data of right heart catheterization and coagulation tests were particularly studied. 12 of these subjects had right heart failure defined by a rise of right ventricular end-diastolic pressure above 10 Torr. Coagulation tests brought evidence of consumption coagulopathy in 8 patients, 7 of whom had right heart failure. Data suggest a significant correlation between right heart failure and coagulation disorders in patients with acute exacerbation of chronic obstructive pulmonary disease. These disturbances, accompanied by reduction of pulmonary vascular area, could be in part related to the presence of microthrombi in pulmonary arterial vessels.

The possible association between acute respiratory failure and disseminated intravascular coagulation was examined in eight patients with severe acute respiratory failure--a condition characterized by tachypnea, right to left intrapulmonary shunting of blood greater than 30 per cent of cardiac output, increased pulmonary artery pressure with low or normal pulmonary artery wedge pressure and roentgenologic interstitial pulmonary edema. Treatment consisted of mechanical ventilation with positive end expiratory pressure sufficient to minimize intrapulmonary shunting. There was no abnormality in platelet concentration fibrin split product concentration, fibrinogen concentration, prothrombin time or activated partial thromboplastin time during the period of most severe respiratory failure in any patient. However, mean platelet concentration fell to 90,000+/-9,000 per cubic millimeter, less than 0.001, and mean fibrin split product levels rose to 60+/-10 micrograms per milliliter, p less than 0.05, the fourth day after the onset of acute respiratory failure. No significant change occurred in other coagulation parameters. Disseminated intravascular coagulation developed in none of the patients nor was there any correlation between coagulation abnormalities and severity of acute respiratory failure that would suggest a cause and effect relationship.

Patients with shock lung syndrome were identified as those who developed acute respiratory failure after a profound episode of hypotension secondary to hemorrhagic, gram-negative, or endotoxic shock. In this study, each of the 10 patients with shock lung syndrome received methylprednisolone sodium succinate, 30 mg. per kilogram, intravenously every 6 hours for 48 hours. In addition, all patients were supported with mechanical ventilation, with or without positive end-expiratory pressure (PEEP). Arterial oxygenation improved markedly, and pulmonary edema resolved in all patients. Nine were discharged from the hospital and one died subsequently of disseminated intravascular coagulation. This study demonstrated a significant improvement in mortality rate with repeated pharmacologic doses of methylprednisolone compared to previously reported mortality rates of 60 to 90 per cent in patients with shock lung syndrome treated without repeated pharmacologic doses of steroid therapy.

Acute promyelocytic leukemia (APL) is associated with a high incidence of disseminated intravascular coagulation (DIC) and early hemorrhagic death. The risk of early fatal hemorrhage is increased when high peripheral-blood blast count and severe DIC accompanied by visceral hemorrhage are present at diagnosis. Progressive cytolysis induced by daily increased doses of chemotherapy, or differentiation all-trans-retinoic acid (ATRA) therapy have been proposed for initial control of DIC, but both are dangerous in hyperleukocytic APL patients. We report our results obtained in three high-risk APL patients treated with a combination of conventional chemotherapy and ATRA. All patients had documented hyperleukocytic APL [M3 or M3-variant subtype, (15, 17) translocation] with DIC, and all had critical clinical course before treatment. Patient 1 presented with cerebral hemorrhage, patients 2 and 3 had acute respiratory failure probably due to pulmonary leukemic infiltration and pulmonary hemorrhage. In order to minimize the severity of DIC during chemotherapy-induced acute cytolysis, ATRA (45 mg/m2 per day) was started on the first or second day of chemotherapy and withdrawn when complete remission (CR) was achieved. Despite adverse clinical features, CR was obtained in these three high-risk patients. Patient 1 showed no increase of cerebral bleeding during therapy. Patients 2 and 3 required transient intensive care, with mechanical ventilation from day 4 to day 11 for one of them. Differentiating granular cells were present in peripheral blood of all patients from the day 5, 12 and 8 of cytotoxic therapy. For the three patients, the number of days with white blood cell count < 1 x 10(9)/l was only 2, 7 and 11 days respectively. These results suggest that differentiation therapy with ATRA may be useful even in hyperleukocytic APL patients, when ATRA is used in combination with chemotherapy. The mechanisms of this putative beneficial effect are discussed.

Thrombohemorrhagic risk is one of the main limiting factors in extracorporeal circulation. We describe here our experience in managing some life-threatening hematological complications in 58 patients with acute respiratory failure treated with long-term extracorporeal assistance. These patients were studied by clinical and laboratory means to assess questions related to heparin monitoring, coagulation complications and bleeding incidence. We found that two clotting tests, activated partial thromboplastin time (APTT) and activated clotting time (ACT) can be easily used to assess the safety of anticoagulant treatment (therapeutic ranges: APTT from 55 to 95 sec and ACT from 170 to 220 sec). A certain degree of coagulation activation, despite heparin, was indicated by the constant finding of thrombin-antithrombin complexes, while fibrinolytic activation, measured as plasminogen activator activity, was confined to the time of bypass connection and was of no clinical consequence. Platelet function was always impaired without relation to the platelet loss. Disseminated intravascular coagulation (DIC) (13 episodes) and severe bleeding (11 episodes) were major complications. DIC was corrected with a good outcome for 8 of 13 patients, while severe bleeding was correlated with a poor outcome in 8 of the 11 patients, probably because of the severity of the underlying disease.

Though the incidence, prevalence, and mortality of tuberculosis have decreased so quickly in last thirty years in Japan, we still have many persons suffering from so called tuberculosis sequelae who complain pulmonary symptoms, particularly respiratory failure. As I have been studying this problems for last many years as a part of tuberculosis treatment, I would like to summarize the present status of the problem. 1) Acute respiratory failure is observed in DIC followed by miliary tuberculosis and in far advanced cases. 2) Chronic respiratory failure is common in pulmonary tuberculosis sequelae. Sexual ratio, male to female is three to two and average age is 60.5. It is quite reasonable that advanced restrictive failure, %VC less than 40%, occurs in 70% of all cases, but obstructive disturbance, FEV1.0% less than 55%, was also observed in 40% of cases. It is still not so clear why tuberculosis sequelae shows obstructive ventilatory failure, but the response to obstruction with the administration of beta-stimulant is observed. Advanced hypoxemia, PaO2 less than 50 Torr, is observed in 30% and hypercapnea is observed in 70% of total cases. Clinical right heart disturbance is observed in 80% of cases. 3) Based on to calculation from the number of interval organ failure and questionnaire to hospitals, the number of persons suffering from respiratory failure is estimated at 20 per 100,000, and it is presumed that the prevalence of respiratory failure will begin to decrease in two to five years later. 4) Pulmonary hypertension, mPA 28.8 mmHg, and higher PVR, 402, are observed in 90 catheterized cases. alpha-NA Peptide in serum and ACT, RVET by echocardiogram are well related to the value of mPA. 5) Average accumulated survival rate is 50% after three years, and it related closely with PaO2. 6) Long term oxygen therapy is the most reasonable and practical treatment for not only to increase the life span but also to improve QOL of the patient. Exercise training is also effective. Almitrine (clinical trial base in Japan), Doxopram and other drugs are effective to recover hypoxemia and to improve pulmonary hypertension. Home mechanical ventilation just started in Japan, and two cases for tuberculosis sequelae are reported. In persons suffering from respiratory failure, special consideration should be made on the treatment of complications, for example abdominal surgery. 7) Social measures, for example, residence with sheltered workshop and vocational training center are quite important to care the respiratory failure due to tuberculosis sequelae. Profile and follow up study of the residence and the training center are reported.(ABSTRACT TRUNCATED AT 400 WORDS)

A case of emphysematous pyelonephritis with septic shock was present in a 58-year-old diabetic woman. The spontaneous production of gas was present within the right renal pelvis in kidney-ureter-bladder X-ray. The patient's condition deteriorated rapidly after admission, became complicated with acute renal failure, disseminated intravascular coagulation and acute respiratory failure. Transurethral drainage of the pelvis using a 6 Fr. UPJ occlusion balloon catheter and endotracheal intubation with respiratory assistance were performed as a life-saving procedure. The optimal therapy with surgical or conservative approach for such a severe condition is discussed. The use of transurethral drainage of pelvis as a non-invasive treatment is suggested.

A previously healthy 40-year-old woman was admitted with severe dyspnea, cough and slight fever. Chest X-ray film revealed bilateral widespread opaque infiltration with ground glass shadows around it. The laboratory examination showed moderate hepatic and muscular injury with disseminated intravascular coagulation. In addition her arterial blood gas showed severe hypoxemia (PaO2: 25 Torr under room air). Moreover, about 1 week prior to admission, 2 baby budgerigars she had been raising for half a year died. Because of this history and multi-organ injuries, this disease was considered to be acute pneumonia owing to fulminant psittacosis causing acute respiratory failure. On the first day of admission, she was intubated and ventilated mechanically with an oxygen concentration (FIO2) of 100%. Subsequently, treatment with intravenous minocycline (400 mg/day), heparin for D.I.C. and corticosteroid were started. Abnormal findings in both chest X-ray and several laboratory parameters improved gradually though fever continued for a week. On the 14th day of her hospital stay, she was weaned from the ventilator successfully and the administration of corticosteroid and heparin tapered. On the 41st day, she was discharged without any symptoms. Results of complement fixation (CF) antibodies against chlamydia on paired sera showed a significant rise from 1:32 to 1:256. Moreover, both IgG and IgM antibodies for Chlamydia psittaci with microplate immunofluorescent antibody technique (MFA) showed an 8 times' rise during 10 days after admission. The definitive diagnosis was made with positive isolation of C. psittaci from both the throat swab of this patient and the spleen and liver of the dead budgerigar by the cell culture method. Psittacosis should always be borne in mind as a possible cause of fulminant pneumonia with acute respiratory failure, and such a situation can be handled successfully if emergency care including mechanical ventilation is available.

A wide spectrum of clinicopathological changes have been described in 50 cases of ARF following viperine snake bite studied prospectively over a 15-year period. Disseminated intravascular coagulation (DIC) was seen in 24/50 cases (Russel's viper bite in 62% and Ecchis carinatus bite in 42% of subjects). Histological examination of renal tissue obtained 1.5 days to 8 weeks after the bite revealed proliferative glomerular changes in 17 cases. These were characterized by ballooning of the capillaries, thickening and splitting of glomerular basement membrane (GMB), fibrin thrombi in the capillaries, and mesangial cell proliferation most prominently seen in Ecchis carinatus bites resulting in ARF.

From 1958 to 1987, 81 cases of pregnancy-related acute renal failure (PR-ARF) were observed (9% of the total number of acute renal failure [ARF] needing dialysis). In the three successive ten-year periods (1958-67, 1968-77, 1978-87) the incidence of PR-ARF fell from 43% to 2.8% with respect to the total number of ARF, and from 1/3,000 to 1/15,000 with respect to the total number of pregnancies. Maternal mortality was high (32%), with 5 cases of death in the last ten years. Irreversible renal damage was recorded in 11.6% of PR-ARF, and, in particular, in 26.3% of cases in preeclampsia-eclampsia (PE-E). Worse maternal and renal prognosis occurred in PE-E complicated by abruptio placentae. Neither disseminated intravascular coagulation (DIC), microangiopathic hemolytic anemia nor prostacyclin imbalance were significantly related to the severity of renal damage. Heparin therapy did not modify DIC evolution and renal outcome and was aggravated by severe hemorrhagic complications. In conclusion, PR-ARF has become a rare, but still critical occurrence, and the most effective measures would be a program of careful prevention.
