Based on the report of some activity of combination therapy with dacarbazine (DTIC) and interferon alpha-2a (rIFN alpha-2a) in disseminated melanoma, we conducted a phase II study to determine the feasibility and efficacy in a large series of patients. DTIC was administered in 79 patients at the dose of 800 mg/m2 every 3 weeks and rIFN alpha-2a was given daily at the dose of 9 X 10(6) IU for the first 10 weeks and three times a week thereafter. Among the 75 evaluable patients, 25% achieved an objective response, with 8% complete and 17% partial remissions. The regression occurred within a mean time of 1.9 +/- 1.03 months from starting therapy and the mean duration of response was 8.2 +/- 4.2 months. The major side effects were vomiting, anorexia, fever, fatigue, and myalgia. There was one death related to sepsis after myelosuppression. In the other patients bone marrow and liver toxicities were not remarkable. Our data reveal that a combination regimen of rIFN alpha-2a with a cytotoxic agent has some therapeutic activity in the management of advanced malignant melanoma.

A patient with acute myeloblastic leukemia (AML) developed septicemia due to Bacillus cereus with subsequent rhabdomyolysis and myoglobinuric renal failure. He died despite intensive care. Postmortem examination revealed diffuse muscle necrosis with infiltration of Gram-positive bacilli and widespread bacterial microthrombi in various organs. Septicemia associated with rhabdomyolysis has been described in 12 cases. This case represents the first reported case of B. cereus septicemia associated rhabdomyolysis. Renal failure and shock were considered to be the most important prognostic factors, and either direct infiltration or toxin of the bacteria was suggested to be the mechanism of rhabdomyolysis in sepsis. B. cereus can be one of the lethal organisms in immunocompromised patient such as the present case. Rhabdomyolysis should be considered when a patient with septicemia complains of muscle pain. Prompt hydration and correction of acidosis are important to prevent renal failure and shock.

To clarify the mechanisms underlying the loss of body protein during fever and sepsis, we incubated rat muscles with highly purified human leukocytic pyrogen. This polypeptide, which appears identical to interleukin-1, is released by leukocytes and signals the onset of fever in the hypothalamus. In muscles incubated at 37 degrees C, leukocytic pyrogen stimulated net protein degradation by 62 to 118 per cent (P less than 0.001). Proteolysis increased, but rates of muscle-protein synthesis did not change. The pyrogen also dramatically stimulated muscle synthesis of prostaglandin E2, which promotes protein breakdown in this tissue. Addition of indomethacin with leukocytic pyrogen prevented prostaglandin E2 synthesis and abolished the increase in proteolysis. The acceleration of protein breakdown induced by pyrogen was also blocked by Ep-475, an inhibitor of lysosomal thiol proteases. When muscles were incubated at 39 degrees C to mimic fever, protein breakdown increased, but addition of leukocytic pyrogen caused a further marked increase in proteolysis and prostaglandin E2 production. Thus, human leukocytic pyrogen can act on skeletal muscle to stimulate intralysosomal proteolysis by increasing the production of prostaglandin E2. These findings suggest that cyclooxygenase inhibitors may be useful in the treatment of negative nitrogen balance in fever. In addition, the release of prostaglandin E2 induced by leukocytic pyrogen may account for the myalgia that accompanies fever.

The aim of the present study was to analyze the main clinical and evolutive characteristics of a series of 10 patients diagnosed with sepsis by Candida tropicalis over a 5-year period in a Hematology Unit. The mean age of the 10 patients was 23 years (range 13-66 years) with 6 males and 4 females. Eight patients had acute leukemia, 1 non-Hodgkin's lymphoma and another patient had severe bone marrow aplasia. All the patients presented intense granulocytopenia (< 0.5 x 10(9)/L), had intravenous catheters and were receiving wide spectrum antibiotics as treatment for bacterial infection. The diagnosis of the fungal infection was based on the growth of C. tropicalis in blood cultures together with the evidence of tissue involvement by the fungus. Fever (> 38 degrees C) was the initial symptom of the infection in all the patients, being accompanied by myalgia in 5 cases, pleuritic pain in 2 and septic shock in 1. Violaceous erthymatomous pustules disseminated over the trunk and limbs, the histologic study of which demonstrated the presence of C. tropicalis were observed in 9 patients. Septic metastasis were found in the liver (2 cases), serosae (2 cases), the psoas muscle and the brain (1 case), respectively. Eight patients underwent treatment with amphotericin B which was complemented with 5-fluorocytosin in 6, with death occurring in the remaining 2 patients prior to the start of treatment. Three patients died with active fungal infection (2 by cerebral hemorrhage and 1 by septic shock). In 2 patients the infection evolved to chronic systemic candidiasis and in the remaining 5 patients infection was resolved with hemoperipheral values returning to normal. Sepsis by Candida tropicalis is a severe complication in patients with granulocytopenia, being mainly characterized by fever, cutaneous papulae and, to a lesser extent, muscle pain. Amphotericin B alone, or in combination with 5-fluorocytosin constitute a treatment of choice in this infection, which nonetheless is associated with an undisdainful mortality.

Since 1983 we have been involved in the diagnostic work-up and emergency treatment of a female patient now 48 years old who has a mitochondrial myopathy resembling Luft's disease. The syndrome was first described in 1959, and in more detail in 1962, by Luft and et al., who reported a picture of hypermetabolism with high temperature, extreme sweating, tachycardia, dyspnoea at rest, polydipsia, polyphagia and irritability but normal thyroid function. In 1971 and 1976 Haydar and Di Mauro presented a second case and proposed treatment with chloramphenicol. Our patient has the third case of the syndrome reported so far: her case was initially published in 1987. CASE REPORT. Since her 17th year of life the patient had suffered from episodes of fever, tachycardia and sweating. At the age of 32 these attacks worsened, leading to unconsciousness and apnoea. The patient then had to be intubated, ventilated and sometimes resuscitated. The diagnosis of MH susceptibility and Luft's disease was made on biochemical grounds after the first muscle biopsy in 1983. Therapy with chloramphenicol failed. Therapy with beta blockers, vitamin C and K or E, coenzyme Q10 and a high-caloric diet was started in 1985. The patient was registered with an emergency service, which flew her to our ICU whenever she had a severe crisis. For milder episodes she was supplied with an oxygen breathing mask at home. Myalgia increased with the episodes starting in 1988, and the patient needed dantrolene infusions and analgesics at home. To facilitate venepuncture a Port-A-Cath system was implanted in 1987, which had to be removed four times due to infection and sepsis. A muscle biopsy was taken in Rotterdam, which revealed differences in mitochondrial function from the biochemical findings recorded in 1983 and not in keeping with Luft's disease. Unfortunately, the patient was not able to undergo further metabolic investigations or therapeutic trials. ANAESTHESIA. The patient received three local and six general anaesthetics in our clinic. The muscle biopsies, two in 1983 and one in 1985, were performed under local infiltration with procaine and were uneventful. The general anaesthetics were carried out without MH trigger substances following pretreatment with dantrolene for the following surgical procedures: the repair of an extensive arterio-venous fistula between the brachiocephalicus trunk and the right jugular and subclavian vein, revision of the sternum cerclage, implantations and explanations of infectious Port-A-Cath systems. We used etomidate, propofol and fentanyl or alfentanil with nitrous oxide and oxygen for induction and maintenance of anaesthesia. Muscle relaxation was induced with vecuronium or atracurium. All cardiovascular, respiratory, metabolic and temperature measurements stayed in normal ranges. After the extensive vascular repair (av fistula) the patient had to be mechanically ventilated for some hours until normal body temperature was restored. At the end of all other periods of anaesthesia she was extubated in the operating theatre. In five cases the postoperative period was uneventful. Only once she developed a crisis with hyperthermia, tachycardia, sweating and dyspnoea. INTENSIVE CARE. From 1985 to 1992 the patient was treated in our ICU 21 times. On 11 occasions she was already intubated and being ventilated by the emergency service on arrival. Extubation was usually possible within 2-20 h. During the crisis, heart rate was about 160-190 per minute and temperature above 40 degrees C. Serum values of CK, glucose, BUN, electrolytes, lactate and thyroid hormones were always in the normal ranges. Blood gas controls showed a constant respiratory alkalosis, arterial pCO2 values decreasing to 20 mm Hg or less. In addition to mechanical ventilation, treatment consisted in dantrolene infusions and droperidol injections, supplemented from 1989 onward with piritramide injections because of the increased severity of myalgia. In 1991 we gave propofol by

We report a rare case of non-menstrual toxic shock syndrome (TSS) in the course of Staphylococcus aureus sepsis in a 31-year-old primigravida who developed high fever and severe pulmonary and cardiovascular failure within a few hours at the end of the 29th week of a twin pregnancy. Mechanical ventilation was necessary due to signs of adult respiratory distress syndrome (ARDS) and catecholamines were needed to maintain a somewhat adequate blood pressure. A forceps delivery was performed immediately. Postoperatively, the patient was brought to the intensive care unit (ICU) due to the suspicion of severe septic shock. In addition to the extreme cardiovascular instability and massive disturbance of pulmonary gas exchange, the clinical picture was characterised by a disseminated intravascular coagulopathy (DIC) with marked petechial bleeding and ecchymoses on all extremities. Moreover, a confluent, spotty exanthem of the trunk and extremities could be seen. Despite all therapeutic efforts, the patient died within a few hours after admission to the ICU with signs of multiorgan failure. Post-mortem, multiple staphylococcal abscesses were found in the kidneys, liver, and uterus. Moreover, acute ulcerous endocarditis of the mitral valve and septic myocardial foci with myocarditis were seen. The Staph. aureus strain isolated from the blood cultures was shown to produce TSS toxin 1 (TSST-1) and enterotoxin B. In summary, the clinical picture can be interpreted as severe staphylococcal sepsis complicated by TSS. TSS is a specific type of infectious disease, occurring mainly in young women during the menstrual period (80%-90%), but it has also been reported in non-menstrual cases (10%-20%). It is characterised by sudden-onset high fever, hypotension, rash, mucosal hyperaemia, and various additional symptoms such as myalgia, vomiting, and diarrhoea. The clinical course depends on the extent of the organ failure due to decreased tissue perfusion during hypotension. Severe cases are accompanied by multiple organ-system failure including impaired renal function, which is reversible in nearly all cases. Respiratory failure ranges from interstitial and alveolar aedema to ARDS in 10% of cases; severe DIC is seen in 10%-15%. Another severe clinical complication is cardiac insufficiency. The etiology of TSS is based on a localized or, rarely, systemic infection with certain Staph. aureus strains that are capable of producing toxins, the most important one being TSST-1. Staph. aureus strains can also produce various other enterotoxins that may be involved in the pathogenesis of TSS. The pathogenetic importance of the toxins is supported by the antibody titers in TSS patients: more than 80% of healthy adults show high levels of antibody titers, whereas 90% of TSS patients exhibit low levels in the acute phase followed by a significant increase during convalescence. It is not clear whether the toxins cause TSS by a direct effect or by release of mediators due to their function as superantigens. The clinical characteristics of non-menstrual TSS are identical to those of menstrual TSS, but it can occur in many clinical settings in both sexes at any age. Severe clinical courses are more frequent in non-menstrual TSS: the mortality is about 8%-11% in non-menstrual TSS compared to 2%-5% in menstrual TSS. The diagnosis is based mainly on clinical signs and the isolation of toxin-producing Staph. aureus strains. Besides antibiotic therapy, treatment is primarily directed to the correction of hypotension and additional organ-system failure. Other therapeutic measures such as the elimination of toxins by plasma separation or the administration of antibodies or gamma-globulins are subjects of investigation with no general recommendations at this time.

Of all foodborne infectious diseases, infection with Vibrio vulnificus is one of the most severe; the case-fatality rate for V. vulnificus septicemia exceeds 50%. In immunocompromised hosts V. vulnificus infection can cause fever, nausea, myalgia, and abdominal cramps 24-48 hours after eating contaminated food; because the organism can cross the intestinal mucosa rapidly, sepsis and cutaneous bullae can occur within 36 hours of the initial onset of symptoms. Cases are most commonly reported during warm-weather months (April-November) and often are associated with eating raw oysters. During April 1993-May 1996, a total of 16 cases of V. vulnificus infection were reported in Los Angeles county. Fifteen (94%) of these patients were primarily Spanish-speaking, 12 (75%) had preexisting liver disease (associated with alcohol use or viral hepatitis), all were septicemic, and all had eaten raw oysters 1-2 days before onset of symptoms. In May 1996, three deaths related to V. vulnificus infection among primarily Spanish-speaking persons were reported to the Los Angeles County Department of Health Services (LACDHS). This report summarizes the findings of the investigations of these fatal cases and illustrates the importance of prevention strategies for persons with preexisting liver disease.

The objective of this paper is to report 5 cases of rhabdomyolysis (RML) in patients with acute leukemia (AL). This occurred consecutively after the administration of chemotherapy, during the ensuing period of myelosuppression. Thirty-six patients with AL received, in a three-month period, 51 cycles of combined chemotherapy which included, in all of them, cytosine arabinoside (ARA-C); among them, along with myelosuppression, five experienced fever, infectious complications, gastrointestinal tract symptoms and severe myalgias. Serum creatine kinase (CK), liver function tests and a light microscopy muscle biopsy were performed on all of them. Ten-17 days after receiving chemotherapy, five patients (4 males and 1 female) with acute lymphoblastic leukemia developed incapacitating myalgias in neck, thighs and arms. CK and/or alanine aminotransferase and aspartate aminotransferase were increased 5-24 times above the normal range in four of these patients, and the muscle biopsy showed focal RML in all five. Myalgias were self-limited and lasted 4-10 days. In addition to the chemotherapy, other factors known to be capable of producing RML, such as sepsis, other medications, and dehydration were found. In conclusion, myalgias were due to focal RML produced probably by a combination of factors, particularly the chemotherapy along with dehydration due to gastrointestinal complications, infection, and the use of diverse antibiotics. The endemic nature of the finding in such a short period of time is outstanding.

Tropical pyomyositis is an infection of large muscle groups that can lead to sepsis and death. The most common etiologic agent is Staphylococcus aureus. It usually occurs in patients living in the tropics but is seen with increasing frequency in temperate climates, particularly in immunosuppressed patients, where it may be misdiagnosed and may cause severe morbidity and mortality. Diagnosis is based on the examination of pus from a muscle aspirate and treatment consists of surgical incision, drainage and appropriate antibiotic therapy. It is stressed to take into account pyomyositis in the differential diagnosis of immunocompromised patients with "cryptic" myalgia.

Infection, trauma, and injury result in a stereotypical response that includes loss of food appetite, increased sleepiness, muscle aches, and fever. For thousands of years fever was considered a protective response, and fevers were induced by physicians to combat certain infections. But with the advent of antipyretic drugs, physicians started to reduce fevers, and fever therapy was virtually abandoned. As a result of (1) studies on the evolution of fever, (2) further understanding of just how tightly the process of fever is regulated, and (3) detailed studies on how fever affects host morbidity and mortality, the view of fever as a host defense response has reemerged. However, data indicate that not all fevers are protective and that high fevers are maladaptive. These issues are discussed in the context of the evolution of host defense responses versus modern medical technology. In short, we speculate that patients who would not have survived severe sepsis in the past are now being kept alive and that the occasionally high fevers seen in these patients may be maladaptive.
