In the early 1970s an increased prevalence of gallstones was reported in adults and children with immunoglobulin deficiency. As the advent of ultrasonography has largely changed the diagnostic approach to gallstones, we have reevaluated the prevalence of cholelithiasis in a group including 37 patients with common variable immunodeficiency and seven patients with other forms of primary immunodeficiency. All patients were receiving intravenous gammaglobulin replacement since 1983 or, in more recent cases, soon after the diagnosis was made, and therefore had relatively few infections. All patients underwent a hepatobiliary ultrasonogram and blood sampling. Data were compared, after age and sex standardization, with those obtained by the GREPCO in a free-living population of 1239 men and 1081 women. Only two women with immunoglobulin deficiency had gallstones. One of these was obese and had had one pregnancy. Both were asymptomatic. None of the patients studied had a history of cholecystectomy or evidence of biliary sludge. Thus, the observed prevalence rates of gallstone disease were 8.7% in women and 0% in males, respectively, against expected values of 9.5% and 3.2%. Immunodeficient patients expressed several putative risk factors for gallstones in the low range (body mass index, total and HDL cholesterol, and blood glucose in both sexes, and triglycerides in men). We conclude that gallstone disease is not more frequent in patients with immunodeficiency syndromes undergoing immunoglobulin therapy than in the general population.

Common variable hypogammaglobulinemia (immunodeficiency), a disorder characterized by late-onset immunoglobulin deficiency and lack of humoral immunity, has a variable association with bronchiectasis, cholelithiasis, nodular lymphoid hyperplasia, gastrointestinal neoplasia, megaloblastic anemia, and malabsorption. The patient described in this report had all of the above except neoplasia. In addition, he had calcium oxalate renal stones probably secondary to his malabsorption. The first case demonstrating the beneficial effect of home hyperalimentation in patients with severe malabsorption refractory to other treatments is described. Home hyperalimentation overnight allows the patient freedom for daily activities while also being more cost-effective than in-hospital parenteral nutrition.

PENICILLIN TOXICITY IN THE GUINEA PIG MAY BE MANIFESTED IN SEVERAL DIFFERENT WAYS, AND IT IS PROPOSED THAT THESE TOXIC EFFECTS BE CATEGORIZED INTO THREE SYNDROMES: (1) toxic syndrome, characterized by acute fatal illness; (2) hemorrhagic syndrome, characterized by delayed illness with leukopenia and thrombocytopenia, and culminating in massive visceral hemorrhages; (3) chronic syndrome, characterized by retardation of growth and alopecia, a condition somewhat resembling "runt disease." A virus having some of the properties of a parvovirus has been isolated repeatedly from animals ill or dying of penicillin-induced disease. This finding has been construed as being activation of a latent virus by this antibiotic, but the relationship, if any, of the phenomenon of viral activation to the syndromes produced by penicillin and its frequent lethal toxicity is unknown. That a strong association exists, however, has been established. Of some 60 guinea pigs which received injections of penicillin three developed tumors and four others were found to have gallstones. A virus similar or identical to the guinea pig virus also has been isolated from hamsters dying of penicillin-induced disease. It is hypothesized that the absorption of endotoxin, resulting from the well known change in intestinal flora caused by penicillin, produces a state of immunodeficiency which regularly gives rise to activation of a latent virus, and perhaps, rarely, to the development of malignant neoplasms.

Despite the increasing number of patients with the human immunodeficiency virus (HIV) infection, surgical experience with these patients remains limited. A retrospective review over a 9 year period (January 1985 to December 1993) was undertaken to determine the indications, operative management, pathologic findings and outcome of major abdominal surgery in these patients. A total of 51 procedures were performed in 45 patients; 30 patients had acquired immunodeficiency syndrome (AIDS) and 15 patients had asymptomatic HIV infection. Indications included gastrointestinal bleeding, complicated pancreatic pseudocysts, cholelithiasis, bowel obstruction, immune disorders, acute abdomens, elective laparotomy, colostomy formation, menorrhagia and Caesarean section. Pathologic findings directly related to the HIV infection were found in 81% of the AIDS patients and 35% of the asymptomatic HIV infected patients (P < 0.05). These included opportunistic infections, non-Hodgkin's lymphoma, Kaposi's sarcoma, immune disorders, lymphadenopathy and pancreatic pseudocysts. It was noted that AIDS patients had more complications than asymptomatic HIV infected patients with most complications related to chest problems and sepsis (61 vs 7%; P < 0.01). Emergency operations carried a higher complication rate than elective operations though this was not significant. The hospital mortality was 12%. On follow up, 13 of the 25 AIDS patients had died with the median survival of 7 months, while three of the 14 asymptomatic HIV infected patients had died with the median survival of 40 months. Of the remaining patients, the 12 AIDS patients had a median postoperative follow up of 7 months and the 11 asymptomatic HIV infected patients had a median postoperative follow up of 29.5 months.(ABSTRACT TRUNCATED AT 250 WORDS)

Forty-three patients with invasive adenocarcinoma of the gallbladder were postoperatively studied in order to determine their general immunological status as well as the local immunohistological reaction to the tumor. At the end of the follow-up, they formed two groups: 19 living patients (group GL) and 24 dead patients (group GD). As a control group (GC), 21 patients with cholecystectomy or cholelithiasis and without carcinoma were simultaneously evaluated. In GL, most of the tumors were limited to the gallbladder wall, and in GD, most of the tumors were already disseminated at the time of diagnosis. GD presented a lower percentage of peripheral blood B lymphocytes, as compared to GL and GC cases. Skin tests of delayed hypersensitivity were significantly more reactive in GL cases than in GD cases, and less reactive in GD than in GC cases. The immunohistological evaluation of the gallbladder yielded a lower B lymphocyte infiltration in GD tumors than in the control cases. GL cases showed a higher intratumoral lymphocytic and mononuclear cell infiltration than GD cases. Although the clinical stage was higher in GD than in GL cases, there were also significant differences in the local immune response and the general immunological status. Patients with invasive gallbladder adenocarcinoma showing longer postoperative survival revealed normal or increased local and general immunological reactions, whereas patients with disseminated tumors showed an important humoral and cellular secondary immunodeficiency.

This study was performed in patients with hepatitis C virus (HCV) who were treated with hemodialysis to determine the relationships among alanine amino-transferase (ALT) levels, immunoglobulin (Ig) G anti-HCV, IgM anti-HCV core, and HCV RNA. Of 107 patients on hemodialysis, 27 had positive IgG anti-HCV. Eight of the patients who had HCV were evaluated every 8 months during a period of 2 years, using the following selection criteria: positive IgG against c-22, c33-c, 5-1-1, and c100-3 viral peptides; absence of infection by hepatitis A virus, hepatitis B virus, cytomegalo-virus, Epstein-Barr virus, herpes simplex virus, and human immunodeficiency virus, as well as absence of hepatotoxic drugs or cholelithiasis. We considered elevated ALT values as those more than 150% of the upper limit of normal. Three of the patients had persistent elevation of ALT levels, two had alternating elevation of ALT levels, and three had normal ALT levels in all blood samples. Of the 24 blood samples, 11 had elevation of ALT (45.8%) levels that showed positive IgM anti-HCV, but only 7 of these 11 had positive HCV RNA (63.6%). None of the 13 blood samples without elevation of ALT had positive IgM anti-HCV, but 5 had positive HCV RNA (38.5%). We found an excellent correlation between IgM anti-HCV and ALT levels (r = 0.81). There was no statistically significant difference between the mean ALT values on the 12 blood samples that had positive HCV RNA and the mean ALT values of the negative HCV RNA samples (53.5 +/- 28.0 IU/l vs. 37.4 +/- 17.5 IU/l, respectively). IgM anti-HCV is related to the elevation of ALT levels and can be used as a serologic marker to indicate the presence of active HCV induced liver damage. Serum ALT levels do not correlate with the detection of viral genome in sera. IgG anti-HCV is not necessarily associated with HCV RNA or IgM anti-HCV. The absence of IgM and HCV RNA in patients with IgG anti-HCV and normal ALT levels does not necessarily suggest the absence of active HCV infection.

The etiologic and clinical features of cholecystisis in infection due to human immunodeficiency virus (HIV) were studies retrospectively. The charts and histopathologic specimens of 136 HIV-infected patients who underwent cholecystectomy between February 1987 and May 1993 at a large tertiary care center were reviewed. Opportunistic pathogens infecting the 107 patients with AIDS included microsporidia (eight cases-- Enterocytozoon bieneusi in six and Septata intestinalis in two); cytomegalovirus alone (six cases); Cryptosporidium alone (eight cases); cytomegalovirus plus Cryptosporidum (15 cases); and Pneumocystis carinii and Isospora belli (one case each). In addition, histopathologic changes characteristic of Kaposi's sarcoma were seen in one case. Thirty-eight patients with AIDS had acalculous cholecystitis for which no etiologic agent was found. Twenty-eight AIDS patients had cholelithiasis, six with coexistent opportunistic gallbladder infection. In the 107 AIDS patients, no specific symptom was found to be predictive of opportunistic infection of the gallbladder, but such infection was significantly associated with an abnormal abdominal ultrasound (P = .017) and with nonvisualization of the gallbladder by radionucleotide biliary scan (P < .001).

Diarrhea and malabsorption are common findings in patients with the acquired immunodeficiency syndrome (AIDS). The pathogenesis and consequences of malabsorption in human immunodeficiency virus (HIV) infection are similar to those found in non-HIV-related conditions, and are related to both direct intestinal damage and alterations in the coordination of the body's response to feeding. The pathogenesis of malabsorption is multifactorial and includes primary enterocyte injury with partial villus atrophy and crypt hyperplasia, ileal dysfunction with bile salt wasting and fat malabsorption, and exudative enteropathy. Clinical studies show that intestinal cryptosporidiosis leads to excess fecal losses of about 20% for protein and fat. The consequences of malabsorption include decreased appetite; "enterogastrone" effects including dry mouth, decreased gastric acid secretion, decreased rate of gastric emptying, and slowed intestinal transit; anemia resulting from iron, folate, or vitamin B12 malabsorption; and metabolic effects including osteomalacia, gallstones, renal stones, and hypocholesterolemia. Few studies of nutritional therapy have been applied specifically to AIDS patients with malabsorption. Total parenteral nutrition promotes weight gain, although the response to this therapy depends on the underlying clinical problem, with body cell mass repletion noted in patients with malabsorption but predominantly fat gain in patients with systemic infections. Nutritional stabilization also was noted in response to oral administration of a semielemental diet.

We report the first case of acute cholecystitis due to indinavir-induced cholelithiasis in a patient infected with human immunodeficiency virus who had been receiving indinavir for 56 months. Infrared spectroscopy demonstrated that the gallstone was composed of indinavir monohydrate (50%), calcium bilirubinate (28%), calcium palmitate (10%), cholesterol (7%), and proteins (5%). The role of high-level chronic unconjugated hyperbilirubinemia coupled with high blood concentrations of indinavir is discussed.

The paper describes the results of studying the immune status of 1,960 patients with stomach, pancreas, liver, gall bladder, small and large intestine disorders, who were treated in the Central Research Institute of Gastroenterology. The results of the study demonstrate that alimentary system diseases are concomitant with changes in the functional activity of the immune system and development of the systemic immune response aimed at the neutralization and elimination of pathogenic agents. Impaired regulatory and efferent lymphocyte capacities, increased synthesis of cytokines, immunoglobulins, heterologous (anti-viral, anti-bacterial or antigliadin), autologous (to parietal cells, microsome mitochondria, tissue transglutaminase) antibodies, formation of immune complexes, autoimmune reactions and secondary immunodeficiency are specific immune mechanisms of the pathological process development, its synchronization and progression in patients with alimentary system diseases. Changes in the immunological status indices are expressed in varying degree depending on the organ involved, etiological factor, clinical course and stage of the disease, as well as treatment used. The immunological status indices have maximal values in cases of chronic hepatitis, hepatic cirrhosis, peptic or duodenal ulcer, cholelithiasis, chronic pancreatitis, gluten-sensitive enteropathy and minimal values in cases of chronic gastritis, gastroesophageal disease, steatohepatitis and irritable bowel syndrome. These data are sufficient for developing an algorithm of immune diagnostics for a number of alimentary system diseases. The study of immune status indices is of great diagnostic and prognostic value as it defines the etiological factor, intensity of inflammatory, infectious and autoimmune processes as well as disease stage and activity, its forecast and the efficacy of treatment of alimentary system diseases.
