We report a 3-year analysis (1986 to 1989) of the management of 63 home parenteral nutrition patients, 40 with short-bowel syndrome and 23 with chronic intestinal obstruction with or without intestinal resection. Intravenous fluid requirements varied from 0.9 to 6 L/day, and the content of glucose varied between 46 and 531 g/day, protein varied from .0 to 85 g/day, fat from .0 to 100 g/day, sodium from 37 to 695 mEq/day, potassium from 30 to 220 mEq/day, chloride from 60 to 760 mEq/day, and acetate from 0 to 200 mEq/day. Body weight was normalized and well maintained in the majority of patients, but using the strict definition of deficiency as the presence of one abnormal value during 3 years, more than half had abnormal plasma chloride, glucose, alkaline phosphatase, serum glutamic oxaloacetic transaminase, total protein, albumin, selenium, and iron concentrations, and more than a third had low calcium, magnesium, vitamin D, and vitamin C levels. Normochromic anemia was seen in 73% and high blood creatinine associated with low urine volumes in 42%. Most (78%) returned to relatively normal lifestyles, but employability was occasionally impaired by loss of third-party insurance coverage resulting from a therapy that may cost $100,000 per year. Overall mortality was low (5% per year), but 73% needed readmission to hospital, mainly for suspected catheter sepsis. The results indicate that home parenteral nutrition has allowed many patients to survive gut failure and return to work but problems with chronic fluid, electrolyte and micronutrient deficiencies, catheter sepsis, and insurance coverage often restrict optimal rehabilitation.

Hepatic dysfunction is a frequent finding in sepsis and peritonitis. In the present study, hepatic function in experimental peritonitis in the rat was determined by measuring serum levels of bilirubin, alkaline phosphatase (ALP), glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT), together with antipyrine (AP) clearance as a determinant of microsomal function. Peritonitis was induced by intraperitoneal injection of 3 x 10(8) colony-forming units of E. coli together with either 1.0 ml bile or saline. E. coli + bile peritonitis rats had significantly elevated levels of bilirubin, ALP, GOT and GPT as compared with both controls and rats with peritonitis induced by E. coli alone. The derangements gradually increased with time over the 10-hour period studied. In contrast, no reduction of AP clearance was observed in the peritonitis models. On the contrary, AP clearance was enhanced at 10 hours after induction of peritonitis by E. coli alone. In conclusion, hepatic dysfunction as revealed by routine laboratory tests is seen early in experimental peritonitis in the rat, but this is not accompanied by a reduced AP clearance rate.

A 5-year prospective study was performed to monitor liver function tests (LFTs) in patients receiving total parenteral nutrition (TPN). A gradual and progressive rise was seen in the plasma concentration of bilirubin, aspartate transaminase, and alkaline phosphatase. The rate of rise was not increased in patients with LFT abnormalities before the start of TPN. Half of the patients had an episode of sepsis during TPN, but overall abnormal LFTs did not appear more common in these patients than in those without obvious sepsis. Patients with malignant disease, those requiring long-term TPN, and those requiring a nonstandard TPN regimen were more likely to develop raised LFTs.

The progression of changes in biochemical liver test results during moderate and severe sepsis (SS) was studied prospectively in 43 patients admitted to a surgical intensive care unit. Using predetermined criteria, severity of sepsis was assessed by physicians blinded to the liver test results. Linear regression analysis showed that bilirubin levels increased at a rate approximating 0.95 mg/dl/day in patients with SS, whereas alkaline phosphatase levels did not rise initially in these patients. Following peak hyperbilirubinemia, however, alkaline phosphatase levels increased at approximately 4 IU/L/day. In patients with moderate sepsis (MS), bilirubin levels increased slowly (approximately 0.4 mg/dl/day) but alkaline phosphatase levels increased rapidly (approximately 29 IU/L/day). Following peak hyperbilirubinemia, alkaline phosphatase levels did not change. These data define patterns of liver test abnormalities of clinical importance. Rapidly rising bilirubin levels with little change in alkaline phosphatase levels are associated with SS, whereas markedly elevated alkaline phosphatase levels may indicate MS or resolution of SS. In critically ill surgical patients subjected to many potential hepatic insults, recognition of liver dysfunction with these patterns should alert the clinician to the possibility of underlying sepsis.

Patients with the acquired immune deficiency syndrome (AIDS) frequently develop hepatic dysfunction. Although hepatic injury may indirectly result from malnutrition, hypotension, administered medications, sepsis, or other conditions, the hepatic injury is frequently due to opportunistic hepatic infection, directly related to AIDS. Infection with Mycobacterium avium intracellulare typically occurs in patients with advanced immunocompromise and with systemic symptoms due to widely disseminated infection. In contrast, hepatic tuberculosis often occurs with less advanced immunocompromise. Cytomegaloviral infection may produce a hepatitis. Cytomegaloviral and cryptosporidial infections have been implicated as causes of acalculous cholecystitis and of a secondary sclerosing cholangitis. About 10-20% of patients with AIDS have chronic hepatitis B infection. These patients tend to develop minimal hepatic inflammation and necrosis. The clinical findings in patients with hepatic cryptococcal infection are usually due to concomitant extrahepatic infection. Hepatic histoplasmosis usually develops as part of a widely disseminated infection with systemic symptoms. Hepatic involvement by Kaposi's sarcoma is rarely documented ante mortem because an unguided liver biopsy is an insensitive diagnostic procedure. Patients with non-Hodgkin's lymphoma of the liver typically have lymphadenopathy, hepatomegaly, and systemic symptoms. As a pragmatic approach, patients with liver dysfunction and HIV-related disease should have a sonographic or computerized tomographic examination of the liver. Patients with dilated bile ducts should undergo endoscopic retrograde cholangiopancreatography because opportunistic infection may produce biliary obstruction. Patients with a focal hepatic lesion should be considered for a guided liver biopsy. Patients with a significantly elevated serum alkaline phosphatase level should be considered for a percutaneous liver biopsy. When performed for these indications, liver biopsy will demonstrate a significant disease involving the liver in about 50% of patients with AIDS and in about 25% of patients who are HIV seropositive but who are not known to have AIDS. The clinical impact of a diagnostic biopsy is blunted by a lack of efficacious therapy for many opportunistic infections.

Five of 23 patients with recurrent nasopharyngeal carcinoma (NPC) were diagnosed to have bone marrow metastasis. They all had advanced local-regional disease, and were treated with neoadjuvant chemotherapy and definitive radiotherapy after the initial diagnosis. Bone marrow metastasis developed 4-24 months later. The clinical features were anemia (5 of 5), leukopenia (3 of 5), thrombocytopenia (4 of 5), sepsis (3 of 5), tenderness of the sternum (3 of 5), and fever (4 of 5). Patients frequently had elevation of serum lactic dehydrogenase (LDH), alkaline phosphatase (ALK-P), and IgG and IgA antibody titers to Epstein-Barr viral capsid antigen when bone marrow involvement was diagnosed. However, clinical manifestations and laboratory tests were not specific. It is important that three patients had normal bone scans. All five patients had a rapid downhill course; four patients died within 23 days, and the fifth 3 months after the diagnosis of bone marrow metastasis. We concluded that bone marrow was a common metastatic site in NPC patients. Bone marrow metastasis adversely affected patients' survival and required a high index of suspicion for diagnosis. We suggested that bone marrow biopsy should be considered as a routine staging procedure in NPC patients and indicated especially when patients presented with abnormal blood counts, sepsis, bone pain, or tenderness of the sternum. It may be positive in the face of a normal bone scan.

Physicians and surgeons have long recognized that septic illness may be accompanied by abnormal brain functions; however, no systematic, comprehensive study has been done to define the clinical and laboratory features of the syndrome of sepsis-associated encephalopathy. We undertook such a prospective study in a tertiary care hospital and found that of 69 patients with fever and microbial cultures, 32 had marked brain dysfunction, 17 showed mild encephalopathy, and 20 were clinically nonencephalopathic. Severe cases showed obtundation and paratonic rigidity while milder cases showed confusion, inappropriate behavior, inattention, disorientation, and writing errors. There were no focal neurological deficits. The following factors correlated with the severity of brain dysfunction: adult respiratory distress syndrome; fatal outcome; certain types of EEG abnormality; axonal peripheral neuropathy; elevated peripheral white blood cell count; elevated serum levels of alkaline phosphatase, bilirubin, creatinine, phosphate, potassium, and urea; reduced blood pressure and reduced serum albumin level. Our data suggest that brain functions fail with dysfunction of other organs in septic illness. Pathogenetic mechanisms are discussed. The brain dysfunction should be regarded as potentially reversible, even in severely encephalopathic cases. Prompt control of the infection is the most important measure in controlling the encephalopathy and in preventing the increased mortality found with severely encephalopathic patients.

A case is presented of a 57-year-old male patient who underwent total gastrectomy due to gastric adenocarcinoma. During the postoperative period the patient required long-term parenteral nutrition due to a high-debit GI fistula (over 700 ml/day) and sepsis. Two months after parenteral nutrition was started, the patients presented irritability, mucocutaneous lesions and progressive bolding. Serum alkaline phosphatase and zinc levels were lower than normal, although a supplemental 0.03 mg/k/day of zinc was administered. Faced with this zinc deficiency picture, 10 mg zinc sulfate was administered parenterally on a daily basis. The deficiency picture improved markedly over a week's period, and serum zinc and alkaline phosphatase levels returned to normal. The importance of zinc balance control in patients under long-term parenteral nutrition and high fluid debit through GI fistulas is highlighted.

This study was designed to evaluate the effects of endotoxin infusion (0.25 mg/kg) over a 4-hr period on renal function and tubular enzyme activity. Endotoxin administration resulted in a decrease in blood pressure, osmolar clearance, and creatinine clearance (P less than 0.05). The enzyme activities of alkaline phosphatase (ALP) and lactic dehydrogenase (LDH) in the urine increased, as did the serum creatinine (P less than 0.05). There were no significant changes in the renal artery flow, urinary output, heart rate, serum electrolytes, and serum enzyme activities. In contrast, in the saline control group, the renal artery flow increased (P less than 0.05), whereas the serum creatinine, urinary ALP, and urinary LDH decreased over time. All other parameters remained relatively stable. These data suggest that an increase in urinary enzyme activity reflects compromised renal function and is independent of the renal artery flow. This may have clinical application in detecting early renal damage due to endotoxemia or sepsis.

Interleukin-2 (IL-2)-based immunotherapy is associated with profound reversible cholestasis and hyperbilirubinemia. We performed a nonrandomized retrospective and prospective analysis to determine the incidence, characteristics, clinical course, and nature of the IL-2-induced liver dysfunction in patients with cancer. Patients received IL-2 at a dose of 20,000 to 100,000 units (U)/kg thrice daily for up to 5 days. Fifty-one patients on adjuvant treatment protocols received a mean of 10.18 +/- 2.38 IL-2 doses and 11.67 +/- 4.16 doses were delivered to 210 patients with advanced disease during this period. Retrospective analysis of all patients receiving this therapy revealed increases in the following liver function tests expressed as median, 25th percentile, and 75th percentile (range): bilirubin (mg/dL) 4.5, 2.6, 6.5 (.4 to 38.5); alkaline phosphatase (U/L) 256, 179, 378 (56-1680); SGOT (U/L) 80, 52, 117 (18 to 483); SGPT (U/L) 91, 64, 132 (20-540); prothrombin time 13.4, 12.8, 14.5 (10.8 to 35.4); and albumin (g/dL) values decreased (trough) slightly 3.0, 2.8, 3.2 (2.3 to 3.8). Multiple regression analysis revealed several factors that were significantly associated with the increase in bilirubin when jointly considered (model P2 less than or equal to .001) including total IL-2 dosage, increase in creatinine, alkaline phosphatase, weight, and SGOT. Similar increases were noted in a prospectively evaluated group of 10 patients. A return to normal levels of bilirubin was noted within 5.6 days of stopping IL-2. Fasting serum cholylglycine increased from a mean of 32.3 +/- 1.6 to a peak of 1556.0 +/- 625.0 mg/mL. Although conventional ultrasound examinations were unrevealing, tissue ultrasound examinations revealed a mean scatterer spacing (MSS) increase compared to baseline of .10 +/- .04 (P less than .02) suggesting hepatic edema or an infiltrative process. Further, computerized hepatobiliary nuclear medicine scans revealed a delay in uptake (2.2 +/- 0.5 fold greater) and excretion (8.0 +/- 5.9 fold greater) of technetium-99m labeled disofenin. These findings support the development of profound reversible cholestasis as the primary basis for the elevated bilirubin in patients undergoing IL-2 treatment and may have implications for understanding the jaundice observed in some patients postoperatively as well as that associated with sepsis and other inflammatory disorders. Specifically, the release of IL-2 or the induction of other factors similarly induced by IL-2 may be responsible for these findings. Tissue ultrasound and computerized hepatobiliary scans provide additional noninvasive assessments of liver function and physiology.
