Reccurrent abnormalities of polymorphonuclear leukocyte and monocyte bactericidal activity were demonstrated in a patient with sarcoidosis. Defective function occurred during hypercalcemia complicating recovery from Listeria meningitis, and during separate, unrelated episodes of erythema nodosum, staphylococcal cellulitis, and pneumococcal pneumonia. Leukocyte morphology, oxidative metabolism, degranulation, and content of myeloperoxidase and lysozyme were normal, but low leukocyte alkaline phosphatase activity was demonstrable on one occasion. Despite defective bactericidal function of monocytes, the patient's macrophages killed bacteria normally. The relationship between an intermittent leukocyte bactericidal defect and sarcoidosis is unclear; however, further studies of leukocyte function in sarcoidosis patients with opportunistic infection are indicated.

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.

Four patients with acquired immunodeficiency syndrome (AIDS) (CDC group IV) were investigated for biliary disease because of the presence of both severe upper abdominal pain and raised levels of serum alkaline phosphatase. None was clinically jaundiced. Upper abdominal ultrasound was abnormal in three. All had endoscopic retrograde cholangiographic evidence of both an intrahepatic sclerosing cholangitis suggestive of primary sclerosing cholangitis and an irregular suprapapillary common bile duct dilation suggestive of papillary stenosis. Three had evidence of gastrointestinal cryptosporidiosis and two of disseminated cytomegalovirus infection. Endoscopic sphincterotomy, performed in two patients, gave good pain relief. We propose the name 'AIDS sclerosing cholangitis' for this form of secondary cholangitis. The cause of this disorder remains unclear. Recent evidence is discussed which suggests that it is not due to HIV itself but to an opportunistic infection. Cryptosporidium appears to be the most likely candidate.

A 15-yr-old girl presented with complaints of right upper quadrant pain and jaundice. Elevation of serum alkaline phosphatase, signs of protal hypertension, and computed tomographic scan findings suggested a diagnosis of primary sclerosing cholangitis. However, cultures of the bile and of the common bile duct specimen obtained during a surgical procedure grew Cryptococcus neoformans. Treatment with amphotericin B was begun. An episode of upper gastrointestinal bleeding, however, led to the hepatorenal syndrome, and the patient died before antifungal therapy was completed. At autopsy, active sclerosing cholangitis associated with cryptococci involved the common bile duct. We suggest that opportunistic infection of the biliary tree should be considered in pediatric patients with presumed primary sclerosing cholangitis.

Clinical characteristics associated with bacillary angiomatosis and bacillary peliosis (BAP) in patients with human immunodeficiency virus (HIV) infection were evaluated in a case-control study; 42 case-patients and 84 controls were matched by clinical care institution. Case-patients presented with fever (temperature, > 37.8 degrees C; 93%), a median CD4 lymphocyte count of 21/mm3, cutaneous or subcutaneous vascular lesions (55%), lymphadenopathy (21%), and/or abdominal symptoms (24%). Many case-patients experienced long delays between medical evaluation and diagnosis of BAP (median, 4 weeks; range, 1 day to 24 months). Case-patients were more likely than controls to have fever, lymphadenopathy, hepatomegaly, splenomegaly, a low CD4 lymphocyte count, anemia, or an elevated serum level of alkaline phosphatase (AP) (P < .001). In multivariate analysis, a CD4 lymphocyte count of < 200/mm3 (matched odds ratio [OR], 9.9; P < .09), anemia reflected by a hematocrit value of < 0.36 (OR, 19.7; P < .04), and an elevated AP level of > or = 2.6 mukat/L (OR, 23.9; P < .05) remained associated with disease after therapy with zidovudine was controlled for. BAP should be considered an AIDS-defining opportunistic infection and should be included in the differential diagnosis for febrile, HIV-infected patients with cutaneous or osteolytic lesions, lymphadenopathy, abdominal symptoms, anemia, or an elevated serum level of AP.

It's well known that patients was acquired immunodeficiency syndrome (AIDS) can develop various kinds of hepatobiliopancreatic diseases, for causes related to AIDS and for causes not related to HIV infection. The authors describe a case to their attention due to a suspected acute pancreatitis. The patient presented with abdominal pain, increased serum alkaline phosphatase and amylase levels. Serological test and stool concentration didn't show any opportunistic infection (Cytomegalovirus, Cryptosporidium). Abdominal ultrasonography showed enlargement of the head of the pancreas, gallbladder with biliary sludge, and a little dilatation of the biliary tree. The patient didn't feel better despite the medical treatment, so considering the probability of the migration of calculus, the patient underwent cholecystectomy. After the operation the patient felt better quickly. This case confirms the presence in HIV patients of pancreatitis for causes unrelated to AIDS like cholelithiasis as we showed, alcoholism, hypercalcemia, and the importance of an opportune surgical treatment that was resolutive.

In the first part of our review, we discussed the general evaluation and clinical presentation of the various hepatic infections occurring in patients with AIDS. In addition, we focused on specific hepatic parenchymal infections. In this article, we will discuss the major clinical syndromes arising from opportunistic infections affecting the gallbladder (acalculous cholecystitis), biliary tree (AIDS-cholangiopathy), and pancreas (pancreatitis). Acalculous cholecystitis can develop in patients with AIDS who have not experienced the severe precipitating physiologic stresses normally required in patients without AIDS. The most common presentation is with right upper quadrant (RUQ) pain and tenderness. The diagnosis is a clinical one since there is no standard test, other than surgery. Cholecystectomy is the treatment of choice. The most common AIDS-associated infective complication of the biliary tree is AIDS-cholangiopathy. This is best viewed as a form of secondary sclerosing cholangitis resulting from a variety of opportunistic infections within the biliary tree. Affected persons present with RUQ pain and have marked elevations in the canalicular enzymes, alkaline phosphatase, and gamma-glutamyl transferase. Morphologic abnormalities are identified by endoscopic retrograde cholangiopancreatography. These include stricturing, dilatation, and beading of the biliary tract. Endoscopic sphincterotomy of the papilla of Vater may provide symptomatic relief for patients with papillary stenosis. Opportunistic infections within the pancreas gland have been documented in both pre- and postmortem studies. However, the true incidence of pancreatitis related to infections is unknown. The presentation is similar to that of pancreatitis from other causes. A computerized tomogram of the abdomen is the investigation of choice. Tissue aspiration or biopsy of the pancreas is required to demonstrate the presence of an opportunistic infection. The management is usually supportive, as it is rare that a specific infection is identified and treated.
