A patient with laboratory-acquired Rocky Mountain spotted fever (RMSF) and concomitant influenza virus infection was studied from the third day of clinical illness. The course of his illness was marked by petechial rash, thrombocytopenia, and elevation of fibrin split products. No evidence of complement activation was observed. Plasma proteins were elevated in a pattern characteristic of the "acute phase reaction." The patient recovered completely, and vascular collapse or clinically important disseminated intravascular coagulation had developed. In febrile patients who had influenza or a clinically similar noninfluenzal respiratory syndrome, no changes in coagulation, complement, or plasma proteins developed. We conclude that aberrations in the patient's laboratory values reflected RMSF, and that complement played no critical role in his illness.

The clinical and laboratory findings in four cases of acute renal failure following the onset of influenza A viral infection (Port Chalmers/1/73) are presented. Although the pathophysiologic mechanisms affecting the kidney in these cases varied, the ensuing renal failure in each patient was severe. Findings suggestive of acute myoglobinuria developed in one patient, and disseminated intravascular coagulation (DIC) occurred in another. The role of viruses in the pathogenesis of renal disease is reviewed. Despite inconclusive evidence that the influenza virus can cause human renal disease, the secondary pathways that can be triggered by viral infections may be even more significant in producing various degrees of renal dysfunction. The occurrence of renal failure during an episode of influenza represents a serious complication which may influence significantly the morbidity and mortality of patients with this viral infection.

Two cases of fulminant pneumococcal septicaemia are reported. These occurred 18 and 25 years after splenectomy. These patients had not received pneumococcal vaccination. Disseminated intravascular coagulation developed early and was of decisive significance for the course of the illness with lethal issue. The characteristic clinical picture in pneumococcal speticaemia in asplenic patients may be misinterpreted initially as influenza and meticulous observation is therefore necessary and antibiotic treatment according to current guidelines should be initiated as early possible in febrile episodes.

The combination of tumor necrosis factor (TNF) and interferon-gamma has synergistic bioactivity in numerous preclinical model systems. We have tested this potential synergism in vivo by administration of both cytokines to patients with advanced cancer using overlapping 24-hour continuous intravenous (IV) infusions in a phase I trial. Thirty-six patients were treated with a fixed dose of interferon-gamma (200 micrograms/m2/d) with interpatient dose escalation of TNF (from 5 to 205 micrograms/m2/d). The dose-limiting toxicity at the maximal-tolerated dose (MTD) of TNF (205 micrograms/m2) with interferon-gamma was hypotension. Other toxicities noted included an influenza-like syndrome, transient decreases in circulating leukocyte and platelet counts, subclinical evidence of disseminated intravascular coagulation, and the sporadic occurrence of acute pulmonary toxicity. The recommended phase II dose for this combination schedule is TNF, 136 micrograms/m2, with interferon-gamma, 200 micrograms/m2. The addition of interferon-gamma to TNF resulted in a greater than three-fold increase in toxicity compared with TNF administered as a single agent, supporting the hypothesis that the combination of these cytokines may induce synergistic effects in vivo.

Hantaviruses, the causative agents of HFRS, have become more widely recognized. Epidemiologic evidence indicates that these pathogens are distributed worldwide. People who come into close contact with infected rodents in urban, rural and laboratory environments are at particular risk. Transmission to man occurs mainly via the respiratory tract. The epidemiology of the hantaviruses is intimately linked to the ecology of their principal vertebrate hosts. Four distinct viruses are now recognized within the hantavirus genus and that number is likely to increase to six very soon; however, further investigations are necessary. Much more work is still needed before we fully understand the wide spectrum of clinical signs and symptoms of HFRS as well as the pathogenicity of the different viruses in the hantavirus genus of the Bunyaviridae family. HFRS is difficult to diagnose on clinical grounds alone and serological evidence is often needed. A fourfold rise in IgG antibody titer in a 1-week interval, and the presence of the IgM type of antibodies against hantaviruses are good evidence for an acute hantavirus infection. Physicians should be alert for HFRS each time they deal with patients with acute febrile flu-like illness, renal failure of unknown origin and sometimes hepatic dysfunction. Especially the mild form of HFRS is difficult to diagnose. Acute onset, headache, fever, increased serum creatinine, proteinuria and polyuria are signs and symptoms compatible with a mild form of HFRS. Differential diagnosis should be considered for the following diseases in the endemic areas of HFRS: acute renal failure, hemorrhagic scarlet fever, acute abdomen, leptospirosis, scrub typhus, murine typhus, spotted fevers, non-A, non-B hepatitis, Colorado tick fever, septicemia, dengue, heartstroke and DIC. Treatment of HFRS is mainly supportive. Recently, however, treatment of HFRS patients with ribavirin in China and Korea, within 7 days after onset of fever, resulted in a reduced mortality as well as shortened course of illness.

A sheep farmer's wife who had been assisting with lambing developed an influenza like illness in the 28th week of pregnancy. After five days of malaise she spontaneously delivered a stillborn infant; she became acutely ill during the immediate postpartum period with septicaemic shock, acute renal failure, and disseminated intravascular coagulation. The diagnosis was made by isolation and identification of Chlamydia psittaci from the placenta, fetal heart blood, and fetal lung, together with maternal serological evidence. The prominent histological and ultrastructural appearances of the chlamydial placentitis are described.

Endothelial injury is important in the pathogenesis of thrombosis, atherosclerosis, disseminated intravascular coagulation, and vasculitis. The ability of several common human viruses to infect cultures of endothelial cells obtained from human umbilical veins or bovine thoracic aorta was demonstrated. Indicators of infection included cytopathology, viral growth curves, and antigen detection by immunofluorescence. Herpes simplex virus type 1, adenovirus type 7, measles virus, and parainfluenza virus type 3 infected both human venous and bovine aorta endothelium. Mumps virus, poliovirus type 1, and echovirus type 9 grew only in human venous cells; coxsackievirus B4 infected only bovine arterial cultures; and cytomegalovirus, influenza A/Victoria/75 (H3N2) virus, and respiratory syncytial virus failed to grow in either cell culture. During replication some viruses caused acute lytic changes; some produced chronic, less destructive alterations; and other induced no apparent cytopathology. The results suggest that viral replication within endothelium may be important in the pathogenesis of viral disease of initiation of vessel-wall injury.

The case is presented of a 14-year-old boy in whom influenza B virus infection caused pneumonia, acute renal failure and disseminated intravascular coagulation (DIC). Survival was achieved by prompt treatment of DIC with clotting factors and heparin. DIC should be diligently sought in severe viral infections because appropriate therapy may be life-saving.

A 60-year-old woman who was previously in good health presented with a sore throat, fever, and a flu-like syndrome. Treated initially with acetaminophen and fluids for a presumed viral infection, she had a syncopal episode 4 days later, was admitted to the hospital, and died 3 hours after admission. Laboratory test results suggested sepsis with disseminated intravascular coagulation (DIC), whereas blood cultures grew group A beta-hemolytic streptococci. A postmortem diagnosis of streptococcal toxic shock syndrome was established. It was of particular interest that the pulmonary microcirculation was filled with thrombi that contained numerous gram-positive cocci. Although death from sepsis with DIC is not uncommon, septic pulmonary thrombosis has not been previously described. We speculate that this paradox may reflect unique properties of the virulent strains of Streptococcus pyogenes that are associated with streptococcal toxic shock syndrome.

Toxic Shock Syndrome (TSS) is a potentially fatal illness caused by a particular strain of Staphylococcus aureus. The clinical presentation is similar to that of septic shock. The incidence of TSS peaked in the late 1970s and early 1980s, probably as a result of availability of super absorbent tampons. Although most commonly associated with menstruation, the overall incidence of menstrual and nonmenstrual TSS in men and women ranges from 1 to 3 per 100,000. There are almost equal numbers of menstrual and nonmenstrual cases of TSS identified annually. S aureus, the causative microorganism in cases of TSS, has been isolated from many body tissues. Toxic shock syndrome presents as a flu-like illness with high fever, vomiting, diarrhea, general malaise, and muscle weakness. Nursing and medical management focus on controlling or preventing potentially serious complications, such as adult respiratory distress syndrome, renal failure, electrolyte imbalances, disseminated intravascular coagulation, encephalopathy, and cardiomyopathy. Judicious use of tampons and barrier contraceptive devices may decrease the risk of developing TSS.
