Between 1982 and 1992, 18 cases of pregnancy-related acute renal failure (PR-ARF) were observed (9% of the total number of ARF). Mean age of the women was 32 years (22-40 years). Uterine hemorrhage and preeclampsia/eclampsia were the major causes of ARF, accounting for 61% of the cases. Patchy renal cortical necrosis was suspected in 2 cases whereas signs of disseminated intravascular coagulation (DIC) or microangiopathic hemolytic anemia were present in 6 (33%) and 9 (50%) cases, respectively. Ten women required hemodialysis; and 6 of them, additional plasma exchange sessions. Five patients (28%) died during the acute phase of the illness, mainly due to brain damage, hepatic failure, and sepsis. Among the survivors, a complete (61.5%) or partial recovery (23.1%) was usually seen, but irreversible renal failure was recorded in 2 cases with postpartum hemolytic uremic syndrome (HUS). Short-lasting oligoanuria (< 3 days) represents a good prognostic index. However, the presence of vascular injury (cortical necrosis, HUS) seems to carry a poor prognosis. In conclusion, PR-ARF is still a critical occurrence, associated with serious prognosis for both women and kidneys. So far, the most effective measures remain the careful prevention and the aggressive management of the obstetric complications.

We report a case of alveolar haemorrhage in all probability, attributable to the use of anti-vitamin K. The favourable outcome of this type of disease has rarely been reported with anticoagulants and fibrinolytics, most frequently in a disturbed haematological setting with disseminated intravascular coagulation or profound thrombocytopaenia. One should not forget this diagnosis in cases of acute respiratory failure in association with an alveolar syndrome in an exposed patient due to the fact that the outcome is generally favourable after correcting the disturbed coagulation.

The actual disappearance of pregnancy-related acute renal failure (PR-ARF) is a common "feeling" for nephrologists. The aim of this study was to exactly quantify this event by evaluating epidemiology and the extent of renal damage in PR-ARF. From 1958 to 1994, 84 cases of PR-ARF were observed (5.8% of total number of ARF needing dialysis). In four successive periods (1956-67, 1968-77, 1978-87, 1988-94), the incidence of PR-ARF fell from 43% to 0.5% with respect to the total number of ARF, and from 1/3000 to 1/18,000 with respect to the total number of pregnancies. Maternal mortality in the past was high (31%), but no cases of death in the last period were seen. Irreversible renal damage was recorded in 11.1% of PR-ARF, and, in particular, in 18.7% of cases of preeclampsia-eclampsia (PE-E). The worst maternal and renal prognosis occurred in PE-E that was complicated by abruptio placentae (AP). 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 hemorragic complications. Support therapy with plasma infusion, antithrombin III, and antiplatelet agents seems to be helpful. In conclusion, PR-ARF has become a rare occurrence and, in our experience, no cases of death or irreversible renal damage were observed in the last 7 years. The most important reasons for this favorable evolution seem to be an improved medical care and more effective measures of careful prevention, mainly regarding tempestive delivery.

Human ehrlichiosis is a zoonotic disease, caused by a rickettsia that infects leukocytes. It was described for the first time in the United States of America in 1986. More than 300 cases have been reported in that country. One case has been reported in Portugal, two in France and one more in a tourist coming from Mali (Africa). In Venezuela, a tropical country, where ehrlichiosis is endemic in dogs and horses, the first case of human ehrlichiosis is reported in a seventeen month old girl. She initially had symptoms compatible with a viral illness. Then she developed a rash, acute respiratory failure, hepato-splenomegaly, neurologic abnormalities, renal failure and hematologic alterations including pancytopenia and disseminated intravascular coagulation (DIC). Different diagnoses were given before it was concluded that it was a case of ehrlichiosis. She was treated with tetracycline and very soon recovered. The initial diagnosis was made using buffy coat blood smears stained with Diff Quick Stain. Indirect Immunofluorescence (IFA) test was used to detect antibodies against Ehrlichia chaffeensis (1:126) but not to other rickettsias. Also the presence of platelets with ehrlichia bodies similar to E. platys from dogs, it was demonstrated, in peripheral blood from the child. The presence of these bodies in human platelets has not been previously reported. In this case, it could not be proved that the disease was transmitted by a tick bite. The presence of ehrlichia bodies in platelets from the girl's peripheral blood is also described.

A 94-year-old man who had been admitted to our hospital for the treatment of senile dementia and restless behavior exhibited consciousness disturbances, acute respiratory failure, high fever, and thrombocytopenia the day after receiving haloperidol as prescribed by a psychiatrist. On the fourth day following administration of haloperidol, acute renal failure with rhabdomyolysis and disseminated intravascular coagulation (DIC) developed in the patient, who was accordingly given a diagnosis of haloperidol-induced neuroleptic malignant syndrome (NMS) associated with DIC. He was then given heparin and antithrombin III, and his DIC symptoms improved soon thereafter. Elevated plasma levels of tissue factor and tumor necrosis factor-alpha (TNF-alpha) were sustained during this therapy course. Other cytokines, including interleukin IL-1 beta, IL-2 and IL-6, were not elevated. There are activation of extrinsic coagulation and an elevated level of TNF-alpha during acute renal failure and rhabdomyolysis associated with NMS, which is thought to trigger the onset of DIC.

A 62-year-old woman was admitted because of a tumor on her right thigh, fever, generalized lymphadenopathy, and diffuse nodular shadows on chest X-ray films. She was given a diagnosis of miliary tuberculosis based on the findings of a cervical lymph-node biopsy and a broncho-alveolar lavage. Acute respiratory failure and disseminated intravascular coagulation developed, but resolved after the start of anti-tuberculous therapy. The tumor on the right thigh was diagnosed as a subcutaneous tuberculous abscess because tuberculous bacilli were detected in tumor tissue samples obtained by aspiration. The patient's fever disappeared and the abnormal shadows on her chest X-ray films receded significantly after drainage of the subcutaneous abscess. These findings suggested that miliary tuberculosis was associated with the subcutaneous tuberculous abscess in this case.

A 34-year-old obese woman with human immunodeficiency virus (HIV) infection diagnosed a year earlier was seen because of nausea, vomiting, and intermittent diarrhea for 3 weeks. Her current medications included zidovudine. Physical examination revealed tachypnea and tender hepatomegaly. Computed tomography of the abdomen showed hepatomegaly with fatty infiltration. Liver enzymes were within normal range except for elevated lactate dehydrogenase (LDH). The serum bicarbonate value was low, with a lactate level three times normal. The tachypnea and dyspnea worsened as lactate concentrations rapidly increased to 15 times normal. Although her Po2 and cardiac index were initially adequate, the patient had acute respiratory failure. She died with multiorgan dysfunction, including hepatic failure, severe lactic acidemia, disseminated intravascular coagulation, and renal failure. Autopsy revealed hepatomegaly and massive steatosis. Physicians should consider lactic acidosis in patients taking zidovudine and having unexplained tachypnea, dyspnea, and low serum bicarbonate concentrations.

Sepsis and its complications are severe clinical syndrome that is caused by systemic inflammatory response of the host to infection. Despite the use of common and numerous new therapeutic protocols, mortality from this severe disease is still very high. In the study are presented 155 patients (111 males, 44 females) of average age 49.6 years with mean septic score 12.9 (2-40). Mortality in our patients was 20.6%, septic shock developed in 31.6%, ARF in 20.0%, DIC in 12.9%, and MODS in 25.8% of patients. Positive correlation existed between initial sepsis score and mortality. Older age and the presence of primary diseases (34.2% of patients) were associated with significantly higher septic score and were good prognostic factor for the poor outcome of sepsis. Between mean arterial pressure in the first 24 h after the admission and mortality existed negative correlation (p < 0.05). Positive hemocultures were found in 69.7%, and bacterial infection in 78.7% of patients. GP bacteremia was found in 55.6% of patients and GN in 45.4% of all positive hemocultures. Confirmed bacteremia and bacteremia caused by GPB were associated with the higher mortality rate compared to the patients with negative hemocultures and GN bacteremia (p < 0.05). Concentrations of fibrinogen and urea in the blood at the admission in the patients with sepsis were very good prognostic factors of the disease outcome, and leukopenia, leukocytosis and neutropenia were associated with the increased mortality. Negative correlation existed between fibrinogen concentration and mortality (p < 0.001), while positive correlation (p < 0.001) existed between urea concentration and mortality. In the absence of more efficacious therapeutic protocols, fast recognition of the sepsis, evaluation of its severity, knowledge of the risk factors for its poor outcome and aggressive use of antibiotic and existing supportive therapy can significantly decrease high mortality of this too severe clinical syndrome.

A 66-year-old male was admitted to our hospital, presenting a high fever and generalized erythema on June 9, 1999. Physical examination revealed many eschars on his legs. Laboratory examinations were as follows: platelet counts, 5.5 x 10(4)/microliter: FDP, 25 micrograms/ml: TAT, 70.9 ng/ml: GOT, 177 IU/l, GPT, 174 IU/l: CRP, 32.3 mg/dl. Based on these findings, he was diagnosed as having rickettsiosis with DIC, and minocycline (200 mg/day) and heparin were started immediately, but had no clinical effect for 3 days. Blood gas analysis showed severe hypoxia and the chest CT scan revealed increased CT value in all lung fields with reticular shadows in the lower fields and pleural effusion, suggested interstitial pneumonia. Methyl-prednisolone pulse therapy was started on June 12, after which he completely recovered. Anti-Rikettia japonica IgM antibody was found to be x8,192 by immunofluorescent test, establishing the diagnosis of Japanese spotted fever. Acute respiratory failure with interstitial pneumonia shadows should be emphasized as a complication of severe rickettsiosis.

In this report, we describe three patients with pulmonary tuberculosis with acute respiratory failure with an extensive tuberculous consolidation in bilateral lung fields. Disseminated intravascular coagulation (DIC) was present in one patient and miliary tuberculosis in two patients. They all developed acute respiratory distress syndrome (ARDS), nessecitating management by mechanical ventilation with a combination therapy of antituberculous agents and methylprednisolone (m-PSL) pulse therapy. Only one patient survived in whom the PaO2/FiO2 ratio recovered rapidly after the initiation of therapy. Two patients whose systemic condition upon admission was critically ill eventually died of hepatic failure and bacterial pneumonia, even though ARDS and pulmonary tuberculosis were successfully treated. Prognosis of pulmonary tuberculosis complicating ARDS and DIC is poor, and these patients need systemic intensive treatment, in which m-PSL therapy may be beneficial.
