Replacement of glucose and albumin in ten patients after hepatic lobectomy shows that hypoglycemia and hypoalbuminemia, the two most common consequences of lobectomy in animals, can be prevented in man. Biosynthesis of protein, cholesterol, and prothrombin are reduced temporarily. In patients having emergency lobectomy, the serum bilirubin and glutamic oxaloacetic transaminase concentrations are statistically greater than in patients having elective lobectomy. Serum ammonia is not elevated and bromsulphalein excretion is normal after bilirubin returns to less than 1 mg/100 ml. Lactic dehydrogenase concentrations in serum are increased and fluctuate in the presence of sepsis or respiratory insufficiency: Mean creatine phosphokinase peaks at concentrations higher than those reported in acute myocardial infarction and returns to normal in three days. Compensatory hyperplasia of the residual lobe occurred in all patients.

The effects of sepsis on skeletal muscle energetics and membrane function are poorly understood, and the time course of changes in energy metabolism are unclear. To clarify these relationships, high energy phosphate ratios, intracellular pH, and phosphocreatine breakdown rates were measured in vivo in the gastrocnemius muscle of adult male Wistar rats after cecal ligation and puncture or sham operation with 31P magnetic resonance spectroscopy. Adenosine triphosphate (ATP) concentration and Na(+)-K+ ATPase and creatine kinase activities were determined in vitro. Within 24 hours, Na(+)-K+ ATPase activity increased by 60% in rats with cecal ligation and puncture, all of which had positive bacterial cultures, as compared to none of the sham-operated controls. Phosphocreatine/ATP ratios decreased by 20% in association with a quantitatively similar increase in phosphocreatine breakdown (9.7 +/- 0.5 vs 11.9 +/- 0.5 mumoles/gm wet wt/sec; p = 0.01). ATP concentrations were maintained, and intracellular pH did not change significantly. In this model, changes in phosphocreatine breakdown were not related to total creatine kinase activity, which did not change significantly, or increases in adenosine 5'-diphosphate (ADP) concentration (62 +/- 8 vs 92 +/- 8 mumols/L; p = 0.02). Thus, in early sepsis before a measurable decrease in pH occurs, ATP is utilized at an increased rate to help maintain ionic balance and/or to support other metabolic processes. Phosphocreatine stores are used to buffer ATP concentrations.

Neuroleptic malignant syndrome is a little-known adverse reaction to neuroleptic administration characterized by hyperpyrexia, leukocytosis, creatine kinase elevations, muscular rigidity, autonomic dysfunction, and alterations in level of consciousness. Neuroleptic malignant syndrome has an associated 20% mortality but can be reversed when treated with neuroleptic discontinuation and administration of bromocriptine and dantrolene. Early diagnosis in the trauma unit may prevent an extensive workup for presumed sepsis. To our knowledge, neuroleptic malignant syndrome has not previously been reported in a multiple trauma patients.

Rhabdomyolysis was evaluated by measurement of total creatine kinase (CK) and lactic dehydrogenase (LDH) in 19 patients with severe sepsis; 12 developed acute renal failure (Group B) and 7 did not (Group A). Results were compared to 7 patients with trauma (Group C) and 6 patients with chronic renal failure and minor infections (Group D). CK was higher (p less than 0.005) in Group B than in A. Results in Group C were similar to those in A. Elevation of CK correlated to increases in creatinine (r = 0.655, p less than 0.005). CK levels of Group D patients were lower than those of Group B. Blood pressure, lactate and pO2 were similar in both groups but thrombopenia was noted in Group B patients. Our results suggest that rhabdomyolysis and thrombopenia play a role in the development of renal failure in patients with severe sepsis.

A study was made of the content of creatine kinase-BB (CK-BB) and lactate in cerebrospinal fluid (CSF) of 202 neonates and infants with perinatal CNS injuries. The relationship was found between the rise of the CK-BB content and the gravity of perinatal CNS injuries. The highest content of CK-BB in CSF was marked in neonates with cerebral disorders complicated by infectious and inflammatory diseases (pneumonia, sepsis). Within the first 5 days of life, the children of this group demonstrated the relationship between the content of CK-BB and lactate of CSF. The measurement of the content of CK-BB in CSF should be used for early diagnosis, assessment of the gravity and course of perinatal CNS injuries in neonates and in infants.

We studied 14 patients with neuromuscular disorders and concomitant infection with human immunodeficiency virus to define clinical syndromes and prognosis. Eight patients had painful sensorimotor peripheral neuropathy; two, chronic inflammatory demyelinating polyneuropathy; two, mononeuropathy or mononeuropathy multiplex; one, recurrent myoglobinuria; and one, chronic proximal weakness and elevated creatine kinase levels. All eight patients with painful neuropathy had overt symptoms of acquired immunodeficiency syndrome. Chronic inflammatory demyelinating polyneuropathy was the first manifestation of acquired immunodeficiency syndrome in both patients with this syndrome. Both died from overwhelming sepsis within six months of the neuropathy's onset. Patients with mononeuropathy multiplex had a variable course. Immunosuppressant medication had no effect in two patients.

In a historical cohort study, acute renal failure developed in 16.5% of 157 patients with rhabdomyolysis over a two-year study period. Underlying clinical, laboratory, and causative factors associated with the development of acute renal failure were examined. Factors predictive of renal failure in this setting, determined by multiple logistic regression analysis, included the degree of serum creatine kinase, serum potassium, and serum phosphorus level elevation; the degree of depression of serum albumin level; and the presence of dehydration at presentation or sepsis as the underlying cause. The predictive model that was developed correctly classified 93% of subjects and was statistically validated.

Although the incidence of Gram-positive sepsis has risen strongly, it is unclear how Gram-positive organisms (without endotoxin) initiate septic shock. We investigated whether two cell wall components from Staphylococcus aureus, peptidoglycan (PepG) and lipoteichoic acid (LTA), can induce the inflammatory response and multiple organ dysfunction syndrome (MODS) associated with septic shock caused by Gram-positive organisms. In cultured macrophages, LTA (10 micrograms/ml), but not PepG (100 micrograms/ml), induces the release of nitric oxide measured as nitrite. PepG, however, caused a 4-fold increase in the production of nitrite elicited by LTA. Furthermore, PepG antibodies inhibited the release of nitrite elicited by killed S. aureus. Administration of both PepG (10 mg/kg; i.v.) and LTA (3 mg/kg; i.v.) in anesthetized rats resulted in the release of tumor necrosis factor alpha and interferon gamma and MODS, as indicated by a decrease in arterial oxygen pressure (lung) and an increase in plasma concentrations of bilirubin and alanine aminotransferase (liver), creatinine and urea (kidney), lipase (pancreas), and creatine kinase (heart or skeletal muscle). There was also the expression of inducible nitric oxide synthase in these organs, circulatory failure, and 50% mortality. These effects were not observed after administration of PepG or LTA alone. Even a high dose of LTA (10 mg/kg) causes only circulatory failure but no MODS. Thus, our results demonstrate that the two bacterial wall components, PepG and LTA, work together to cause systemic inflammation and multiple systems failure associated with Gram-positive organisms.

We describe a 41-year-old patient with adult-onset dermatomyositis who developed persistent pneumomediastinum and severe subcutaneous emphysema due to end-stage interstitial lung disease. The diagnosis of dermatomyositis was based on proximal muscle weakness, electromyographic findings of inflammatory myopathy, and positive findings on muscle biopsy. Low levels of creatine kinase elevation were found at the time of diagnosis (a form of dermatomyositis which has been associated with a poor prognosis). The patient had no signs of cutaneous vasculitis. Despite treatment with prednisone and azathioprine, she died of intercurrent gram-negative sepsis 15 months after the diagnosis of dermatomyositis.

Between June 1986 and October 1992, disseminated toxoplasmosis was diagnosed in 16 AIDS patients. 13 cases were diagnosed at autopsy where multiple organ involvement was documented in all 13. Three patients were diagnosed intra vitam. All 3 survived with appropriate treatment. Clinical features indicative of disseminated toxoplasmosis were: fever of unknown origin between 39 degrees and 40 degrees C in 16 cases, clinical signs suggestive of sepsis or septic shock in 15, with progression to multiorgan failure in 10, disseminated intravascular coagulopathy in 6, confusion, disorientation or apathy in 13 and lack of a systemic pneumocystis carinii prophylaxis in all 16. Typical laboratory markers were: CD4 cell counts below 100 x 10(6)/l in 16 cases, elevation of serum lactic dehydrogenase in 16 and creatine phosphokinase (in 4/6), normal or only slightly elevated C-reactive protein (in 9/11), positive Toxoplasma gondii IgG antibodies in 15/16 and negative IgM antibodies in all 16. Lesions indicative of cerebral toxoplasmosis were visualized on cranial computerized tomography in only 3/10 evaluated patients. In patients with advanced HIV infection presenting with a systemic illness, including the clinical and laboratory features described above, systemic Toxoplasma gondii infection must be included in the differential diagnosis. In these patients, specific and if warranted, invasive diagnostic procedures followed by early vigorous therapeutic intervention should be considered.
