Malaria has become a very uncommon disease in Italy. Recently a variety of circumstances, such as travel to tropical countries as well as immigration from Asia and Africa, have combined to increase the number of malaria cases recorded annually. In this report we describe the use of red cell exchange transfusion and plasma exchange in the treatment of a patient with hyperparasitemic malaria (51% erythrocytes or more parasitized). When first observed the patient was in shock and had signs of cerebral malaria, disseminated intravascular coagulation, and acute respiratory distress syndrome, which in the following 2 days were complicated by acute renal failure. After mefloquine therapy combined with 3 red blood cell exchanges, 2 plasma exchanges, and 10 dialysis sessions over 14 days, the patient recovered completely. This case of severe malaria with multiple complications, treated with mefloquine in conjunction with both exchange transfusion and plasmapheresis, had a successful outcome and lends further support to the possible beneficial role of exchange transfusion in complicated malaria.

Acute infections with group A beta-hemolytic streptococcus normally take a favourable course under therapy with penicillin. Only in a few cases has a completely different manifestation been described with multisystem failure similar to toxic shock syndrome induced by Staphylococcus aureus. We report on 4 patients (1990/91) who showed this manifestation in spite of immediate antibiotic therapy. In 3 patients the suspected portal of entry was the skin, in 1 patient it was unknown. Group A streptococci were grown from blood cultures from all 4 patients. Without an underlying immune deficiency all 4 patients (age 22, 24, 38 and 51) went into septic shock with high fever, hepatic and renal impairment, diarrhea, DIC and cerebral confusion. 2 patients died within a few days after developing acute respiratory distress syndrome and cerebral edema. All strains isolated from the patients were penicillin-sensitive, group A streptococci. 3 of them were M-type 1, which are known to be more invasive. The bacteremia by itself is not sufficient to explain all complications and the high mortality rate. It is probable that streptococcal toxins, such as pyrogenic exotoxin A, streptolysin O, or a new unknown one, play a decisive role.

High-dose interleukin-2 (IL-2) immunotherapy can cause hypotension, respiratory distress, interstitial edema, and thrombocytopenia, similar to endotoxic shock. We have observed that IL-2 has no direct effect on coagulation factors in vitro, but it has been observed to alter the coagulant properties of vascular endothelium. Accordingly, we investigated the possibility that IL-2 infusions initiate plasma fibrinolysis and disseminated intravascular coagulation (DIC). We studied the clinical course, platelet count, and coagulation profile in response to IL-2 infusion in seven patients, two with metastatic melanoma and five with metastatic renal cell carcinoma. Every patient experienced hemodynamic instability and thrombocytopenia, and one patient suffered an unusual complication, mesenteric thrombosis. No patient had appreciable changes in the prothrombin time or the partial thromboplastin time, nor did factors V or VIII decline in the two patients observed. In four patients examined, we found decreased titers of Hageman factor (factor XII), high molecular weight kininogen, prekallikrein, and plasma thromboplastin antecedent, as if these had been consumed by reactions of the intrinsic pathway of thrombin formation. Circulating D-dimer fragments were found in the plasma of every patient at some point during each infusion cycle, and we observed decreased titers of plasminogen in the four patients just mentioned, suggesting that IL-2 infusions initiated fibrinolysis. Taken together, the clotting factor derangements and related toxicity phenomena cannot be ascribed firmly to DIC. Activation of the intrinsic (contact) system of coagulation, however, may provide one link between the vascular endothelial surface alterations caused by IL-2 infusions and the development of the systemic toxicity that resembles septic shock.

Five cases of neonatal infective endocarditis are reported. The mitral, tricuspid and pulmonary valves were involved either alone or in association. The predisposing factors were multiple: umbilical catheter, respiratory distress with assisted ventilation, septicemia, osteoarthritis or gastroenteritis. Only one child had a minor cardiac malformation. The causal organism was a staphylococcus aureus in all cases. All children had disseminated intravascular coagulation and a cardiac murmur. The diagnosis was confirmed by echocardiographic demonstration of bacterial vegetations. Three of the 5 children died despite long-term antibiotic therapy. In one case, a vegetation embolised to the pulmonary artery. In the two cured neonates the vegetations disappeared. These cases illustrate the value of echocardiography which should be performed in all neonates with septicemia or disseminated intravascular coagulation, especially when there is an associated cardiac murmur.

A case of sickle cell disease diagnosed postmortem is described. A 37-year-old black woman presented with anemia, respiratory distress, and abdominal and back pain. Death followed an intramuscular injection of iron, and anaphylaxis was clinically diagnosed. At autopsy, massive fat and necrotic bone marrow embolization of pulmonary and renal vessels was found. In the vertebral column, multifocal areas of ischemic necrosis were present, and proved to be the source of this embolization. Sickled red cells appeared in bone marrow sinusoids, and signs of disseminated intravascular coagulation were present.

We describe a case of severe septicaemia caused by Mycoplasma hominis in a 23 year old patient following childbirth. She developed disseminated intravascular coagulation and acute respiratory distress syndrome which have not hitherto been described in association with septicaemia due to this organism. Investigation and treatment leading to full recovery is outlined.

In this study, we observed the endotoxin induced platelet aggregation, 5-HT and beta-g releases, cellular cAMP decrease, and also the changes of morphology and membrane fluidity of platelet. These changes play an important role in septic shock, especially in disseminated intravascular coagulation (DIC) and respiratory distress syndrome (RDS). After anisodamine (654) intervention all the parameters mentioned above were improved to a certain extent. This preliminary study of the inhibiting mechanism of 654 on rabbit platelets activated by ET supports the clinical possibility of using 654 for relieving DIC and RDS.

During an 18-month oncogenicity study using rats, approximately 10% of the animals developed a form of respiratory distress very similar to that seen in the terminal stages of chronic respiratory disease, commonly associated with Mycoplasma pulmonis infection. Investigation of the lungs of the affected rats revealed not only that they did not have the consolidation usually associated with chronic respiratory disease, but they also appeared macroscopically normal. Further investigation of a number of cases revealed systemic intravascular thrombus formation of the type usually referred to as disseminated intravascular coagulation. Using an antiserum to fibrin we have demonstrated the presence of intravascular fibrin deposits in the lungs of the affected rats and have shown them to be the same as experimentally induced intravascular fibrin deposits induced in rat lungs by the administration of thrombin after blocking the fibrinolytic system. This is the first example of such a phenomenon being recorded in aging rats.

A 32-year-old woman with acute salpingitis had signs and symptoms of sepsis, with hypotension, renal failure, acute respiratory distress syndrome, and disseminated intravascular coagulation. Streptococcus pyogenes group A was grown from blood cultures taken at the onset of illness, and salpingitis was confirmed at laparotomy. The patient recovered after appropriate antimicrobial and intensive supportive therapy.

Hemorrhagic and thrombotic complications are common in sick preterm infants and may reflect inadequate regulation of coagulation. All neonates have low levels of the pivotal regulator antithrombin III (ATIII) compared with adults. Plasma levels of ATIII are very low in preterm infants and are further diminished in infants with respiratory distress, necrotizing enterocolitis, sepsis, or disseminated intravascular coagulation. Babies with lower levels of ATIII in the cord blood have been shown to have a worse outcome than neonates with levels appropriate for gestational age, including higher mortality and increased incidence of intracranial hemorrhages and catheter-related thromboses. The origin of severe ATIII deficiency is unknown. Therapies with plasma replacement or anticoagulation have decreased the incidence and severity of hemorrhagic and thrombotic complications in high-risk infants in several clinical trials. These data lay the groundwork and rationale for potential use of ATIII replacement in deficient preterm infants.
