Three hundred ninety-seven insulin-dependent diabetic dialysis patients were screened by nursing staff for analgesic-seeking behavior. Thirty-eight patients were identified and classified as prescription abusers (n = 26) or illicit drug users (n = 12). The nine cocaine users, when compared with 14 insulin-dependent diabetics on dialysis matched by protocol, were found to be similar in terms of diabetic retinopathy and metabolic neuropathy. Although statistically not significant, cerebrovascular and cardiovascular complications were more common in the study group. Gastroenteropathy with malnutrition was more common the study group (P less than 0.025). Infection rate and severity were markedly worse in the cocaine group: bacterial cellulitis, sepsis, and abscess each increased greater than fourfold. All the visceral infections were in the cocaine-using group. Hepatitis viral antigen and antibody was increased 10-fold in the cocaine users. Recommendations for management of dialysis patients with analgesic-seeking behavior are formulated in light of these findings.

The gastrointestinal tract is a major target of the human immunodeficiency virus. Many AIDS patients have weight loss and/or diarrhea. Parenteral nutrition can be used to treat malnutrition associated with malabsorption. We reviewed retrospectively the clinical course of 22 patients with AIDS and weight loss greater than 10% who received home parenteral nutrition (HPN) for 56.2 patient-months. Mean weight loss was 21.4%, mean duration of HPN 2.55 months, mean age 37.4 years. Fifteen patients gained weight, six stabilized and two continued to lose weight. Nine patients returned to previous activity. Five died. The rates of catheter-related sepsis, complications, and metabolic disturbances were 0.12, 0.25, and 0.12/100 catheter days, respectively, results identical to those reported in other patient populations where HPN is commonly applied. We found that HPN induced weight gain and clinical improvement in most patients without higher risks of sepsis than in patients with malignancies.

Stress and starvation, especially when complicated by sepsis, will give rise to a rapid erosion of the cellular mass, which significantly affects morbidity and mortality. The best clinical evaluation of the nutritional state is obtained from the medical history and the physical examination. In the patient who cannot eat a balanced diet, specialized nutritional support, in the form of either enteral or parenteral nutrition, is required to prevent malnutrition in the normally nourished, or to correct the nutritional state in the malnourished.

During an 11-year period, 41 patients with Crohn's disease were placed on home parenteral nutrition (HPN) for a mean of 1,083 days (range: 33 to 3,258 days). Data were retrospectively analyzed to determine whether HPN had an effect on the course of their disease, i.e., on the number of operative procedures performed and the intensity of required medical therapy. Data represented information obtained during a total of 121 patient-years of HPN for Crohn's disease. The main indications for HPN were short bowel syndrome (66%) and high stoma output. Twenty-four of 41 patients (59%) underwent surgery for Crohn's disease during the course of HPN. There was no significant difference between the number of procedures performed per patient per year of Crohn's disease during pre-HPN and HPN periods (p greater than 0.25). Although there was no significant change in body weight, both serum albumin and transferrin levels increased during HPN (p less than 0.01 and p less than 0.01, respectively). Twenty-nine percent of patients were taking prednisone while on HPN, compared with 54% of patients during the pre-HPN period (p less than 0.01). HPN appeared to result in a significant improvement in the numerically assessed quality of life. During the HPN period, 24 patients had 1 or more HPN-related complications that required 1 to 13 hospital admissions (mean: 1.8). These complications included catheter sepsis in 19 patients, blocked or damaged catheters in 15 patients, and dehydration and/or electrolyte imbalance in 5 patients. Eight patients died, with 7% of deaths secondary to catheter-related sepsis. Although permanent HPN is associated with an identifiable morbidity and mortality and is not associated with a reduction in the frequency of surgery for Crohn's disease, benefits include a decrease in the intensity of medical therapy, an improvement in patients' nutritional state, and a significant perceived improvement in patients' quality of life. Without HPN, we believe all patients would have died secondary to malnutrition and/or dehydration.

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.

Complications that can lead to death during shigellosis include intestinal as well as systemic manifestations. The former include intestinal perforation, toxic megacolon, and dehydration, and the latter include sepsis, hyponatremia, hypoglycemia, seizures and encephalopathy, hemolyticuremic syndrome, pneumonia, and malnutrition. Data on the frequency of these complications come primarily from hospital-based studies, in which sepsis-either with Shigella or with other Enterobacteriaceae-and hypoglycemia are the most common causes of death. Management of these two complications requires broad-spectrum empiric antibiotic treatment of all severely ill, malnourished patients with shigellosis as well as frequent feedings to prevent hypoglycemia. Unfortunately, in developing countries, access to parenteral broad-spectrum antimicrobial agents is often limited, and frequent feedings are often precluded by the severe anorexia that is characteristic of shigellosis. Realistic approaches to the reduction of mortality from shigellosis must continue to focus on prevention and early antimicrobial therapy rather than on treatment of established complications.

To clarify the risk factors contributing to postoperative complications in elderly patients undergoing total gastrectomy, 84 patients with primary gastric cancer were evaluated. Twenty-seven patients were older than 65 years of age; they had much more preoperative cardiac (P = 0.00003), respiratory (P = 0.0008), and multiorgan impairment (P = 0.009) than did the control group (age less than 65 yrs). Although overall morbidities (44.4% vs. 19.2%; P = 0.01) and overall septic complication rates (33.3% vs. 12.2%; P = 0.02) were higher in aged patients, no significant differences between the two groups were found in the incidence of major surgical complications (18.5% in aged patients vs. 10.5% in control groups; P = NS), serious septic (sepsis score greater than 10) complications (18.5% vs. 7.0%; P = NS) and hospital mortalities (11.1% vs. 3.5%; P = NS). In older patients the occurrence of multiorgan impairment and malnutrition was significantly related to postoperative complication rates. These results suggest that the degree of organ impairment rather than age is predictive of postoperative difficulty and should be used in assessing preoperative risk.

Over a 3-year period, 156 of 815 patients admitted to a single institution with acute pancreatitis received total parenteral nutrition (TPN) for 2,572 patient days. Seventy had "simple" acute pancreatitis (group I) and 86 (group II) developed local complex disease (pseudocyst, abscess, or necrotic gland). In groups I and II, respectively, days without oral intake (NPO) were 13.6 +/- 1.5 (SEM) and 24.0 +/- 2.1 (p less than 0.005), hospital days were 19.8 +/- 1.7 and 35.8 +/- 3.2 (p less than 0.005), and duration of TPN was 10.9 +/- 1.0 and 21.0 +/- 2.3 days (p less than 0.005). Thirty-three patients in group I and 53 in group II required exogenous insulin. Alteration of standard formulas was necessary in 87 patients, but cessation of therapy was necessary in only one instance. Twenty catheters were removed for suspected sepsis with only 3 confirmed cases. Fat-based formulas were well tolerated in 15% of patients. During TPN, body weight rose from 95.0 +/- 2.4% to 97.4 +/- 4.3% of ideal in group I and remained at 90.5 +/- 1.8% in group II. Albumin rose from 3.36 +/- 0.10 to 3.50 +/- 0.08 g/dl in group I and from 3.01 +/- 0.07 to 3.35 +/- 0.07 g/dl in group II. The entire cohort differed from 10 randomly chosen patients who did not receive TPN in terms of days NPO (2.8 +/- 0.3) and hospital days (5.5 +/- 0.6). Variables associated with prolongation of hospital stay and time NPO were number of prognostic criteria, local complex disease, and underlying chronic pancreatitis only in select groups. We conclude that during acute pancreatitis, TPN can be administered safely but with careful monitoring and we recommend early aggressive therapy in the subgroups noted above and when underlying malnutrition exists. In the borderline patient, TPN may be administered by peripheral vein until the severity of disease is manifest.

Nutritional support of critically ill patients is important since adverse effects of malnutrition are multiple and common. Nutrition via the enteral route is often preferred over central venous or total parenteral nutrition due to its relative ease of administration, lower cost, and infrequent association with severe complication. Enteral nutrition and infection are related. Infectious complications of sepsis and nosocomial pneumonia can occur, but enteral nutrition also may be important in maintenance of normal gut structure and function, thereby decreasing bacterial translocation and the risk of systemic infection.

There is accumulating evidence that multiple organ failure is not always the result of an established septic focus. Increasing attention has centred on the gut as a reservoir of bacteria (and bacterial endotoxins) that can traverse the intestinal mucosal barrier (a process called 'bacterial translocation') and initiate the septic state. Although the link between haemorrhagic shock and sepsis was recognized decades ago, the full experimental demonstration of this phenomenon is more recent. It was shown to occur in three main settings: physical disruption of the gut mucosa, impaired defence mechanisms and altered gut microbial ecology. Conditions such as haemorrhagic shock, burns, protein malnutrition and sepsis are seen in the severely ill surgical patient or the multiply injured, and are known to cause various combinations of circumstances favourable to bacterial translocation and endotoxin absorption. These may play an important role in the mortality of the critically ill.
