The increased risk of infection among older patients can be divided into three clinical categories: infections increased in incidence, infections showing higher case fatality rates, and infections that are clinically worse, primarily because of late recognition. Among infections that are increased in incidence, the most important by far are tuberculosis and pneumococcal pneumonia. Infections that show higher fatality rates include influenza and--again--pneumococcal pneumonia. Intra-abdominal infections (eg, cholecystitis and appendicitis) are often clinically worse in older patients due to late recognition and delay in surgical intervention.

Gastrointestinal diseases in HIV-infected patients mainly affect the bowel, the oesophagus, and the liver. Most of the hepatic diseases are due to opportunistic infections and associated to AIDS. In the advanced AIDS disease Mycobacterium avium intracellulare is the most frequent bacterial infections agent. Mycobacterium tuberculosis is often diagnosed in less immunocompromised patients. Viral hepatitis (A, B, C, D) is more often diagnosed in HIV-infected patients than in non-infected controls. Non-Hodgkin's lymphoma of the liver is a relatively frequent tumour in HIV-infected patients. Kaposi's sarcoma may also affect the liver. Infections with the cytomegalovirus or cryptococci mainly affect the biliary system causing acalculous cholecystitis or secondary sclerosing cholangitis. In addition to clinical and laboratory diagnostics sonographic and computer tomographic examinations are important. The diagnostic power of sonographic and computer tomographic examinations can be increased by guided biopsies. Biliary diseases can be diagnosed by retrograde endoscopic diagnostic investigations (ERC, ERCP). This overview resumes the most important diagnostic and differential diagnostic data in HIV-associated liver and biliary tract diseases.

Enterocytozoon bieneusi is a common opportunistic pathogen of human patients with acquired immune deficiency syndrome (AIDS) causing significant morbidity and mortality. In a retrospective analysis utilizing conventional histochemical techniques, in situ hybridization, polymerase chain reaction, and ultrastructural examination, we identified 18 simian-immunodeficiency-virus-infected macaques (16 Macaca mulatta, 1 M. nemestrina, and 1 M. cyclopis) with Enterocytozoon infection of the hepatobiliary system and small intestine. The organisms were readily identified in the bile ducts and gall bladder by special stains and by in situ hybridization using a probe directed against the small subunit ribosomal RNA of human origin E. bieneusi. Infection of the biliary system was associated with a nonsuppurative and proliferative cholecystitis and choledochitis. Hepatic involvement was characterized by bridging portal fibrosis and nodular hepatocellular regeneration accompanied by marked bile ductular and septal duct hyperplasia. Ultrastructurally, all developmental stages of the organism were found in direct contact with the host cell cytoplasm; spores and sporoblasts contained a double layer of polar tubes. Sequencing of a 607-bp segment of the small subunit ribosomal RNA revealed 97 and 100% identity to two clones of small subunit ribosomal RNA derived from E. bieneusi of human origin. Extensive morphological and genetic similarities between the simian and human enterocytozoons suggest that experimentally infected macaques may serve as a useful model of microsporidial infection in AIDS.

Achromobacter xylosoxidans is a gram-negative bacterium whose natural habitat has not been clearly defined. It has been isolated from ear discharge and the large intestine of humans and from various hospital or environmental water sources. Infection with A. xylosoxidans in humans has been documented, and resulting illnesses include meningitis, pneumonia, cholecystitis, peritonitis and urinary tract infection. Bacteremia due to A. xylosoxidans is rare, and little information on treatment is available. Two cases of bacteremia due to A. xylosoxidans in patients with hemapoietic malignancies are reported herein. Case 1 involved a 70-yr. male whose clinical diagnosis was IgA lambda-type plasmacytoma. Case 2 involved 72-yr. male whose clinical diagnosis was acute lymphatic leukemia (L2). Both patients had been catheterized. Neutropenia was noted and the white blood cell counts were 20/microliter in case 1 and 35/microliter in case 2 when A. xylosoxidans was isolated from the blood culture. We suggest that bacteremia due to A. xylosoxidans may have been related to the presence of the catheter and neutropenia.

Miliary tuberculosis is a rare form of tuberculosis in industrialized countries. We report on a 69-year-old woman presenting a sepsis syndrome caused by cryptic miliary tuberculosis clinically mimicking a case of cholecystitis with sepsis. The patient died of a multi-organ failure on day 6 of her hospital stay.

Infections of the liver and biliary tract are common during the course of AIDS. A variety of viral, bacterial, fungal, and other opportunistic infections can present with hepatobiliary involvement as either the primary site of infection or secondary to a disseminated process. Coinfection with hepatitis B and C are particularly common due to the shared means of transmission of these viruses with HIV. The typical presenting features of hepatobiliary infections are right upper quadrant (RUQ) pain and abnormal liver function tests. Initial evaluation should include an RUQ ultrasonogram, which will usually identify abnormalities in the biliary tract and may demonstrate some parenchymal abnormalities as well. A liver biopsy is necessary to determine the etiology of focal hepatic lesions or opportunistic infections within hepatic parenchyma when other less invasive tests are negative or inconclusive. Special stains and culture techniques are required to identify specific organisms in the biopsy specimen. HIV-related biliary disorders include acalculous cholecystitis, which is a potentially serious condition requiring prompt recognition and gallbladder decompression. AIDS-cholangiopathy is a form of cholangitis involving the intra- and/or extrahepatic biliary tree. Endoscopic retrograde cholangio-pancreatography (ERCP) is the test of choice, demonstrating the stricturing, dilatation, and beading of bile ducts seen in this condition. Endoscopic sphincterotomy of the papilla of Vater may provide symptomatic relief for patients with papillary stenosis. Opportunistic infections of the pancreas have been reported. Evaluation should include a computerized tomogram of the abdomen and possible pancreatic tissue aspiration or biopsy. Management of pancreatitis is supportive.

Mycobacterium avium complex (MAC) is commonly associated with fever, fatigue, nausea, diarrhea, and cytopenias related to invasion of the intestine and bone marrow. Infection and clinical disease has been reported in other organs as well. We report the first case of cholecystitis associated with MAC infection of the gallbladder.

Infection of the hepatobiliary system is most commonly due to enteric bacteria. We report three unusual cases of acute cholecystitis in which Staphylococcus aureus was the primary pathogen. Infection of the gallbladder with this organism has been rarely described and may be associated with gallstones and obstructive disease as well as acalculous cholecystitis in the setting of staphylococcal bacteremia and endocarditis. Two of our patients had multiple chronic medical conditions and were infected with oxacillin-resistant S. aureus (ORSA) suggesting nosocomial acquisition. Including our cases with a review of the literature, three of nine reports of S. aureus cholecystitis were associated with infectious endocarditis. Thus, the finding of S. aureus cholecystitis with bacteremia is rare and should prompt an investigation for a possible endovascular focus of infection.

Mirizzi syndrome is a very uncommon cause of extrahepatic bile duct obstruction. A stone impacts in the cystic duct or gallbladder neck and causes extrinsic compression and obstruction of the common hepatic duct, aided by a local inflammatory process. Preoperative diagnosis is very important because of the potential risk of bile duct injury during surgery and the local inflammatory process may suggest cholangiocarcinoma. Infection by specific coliform organisms may result in emphysematous cholecystitis in patients with diabetes or those who are immunosuppressed, with mural air being visible. Herein, we report an emphysematous cholecystitis associated with Mirizzi syndrome in a patient with diabetes mellitus.

Infections are usually detected in diabetes mellitus. They may be divided into: common infections such as fungal infections, pulmonary tuberculosis, pneumonia, bacteraemia, urinary tract infections, and diabetic foot infections and specific infections. The latter occur almost exclusively in diabetes and include rhinocerebral mucormycosis, malignant external otitis, emphysematous pyelonephritis, perirenal abscess, emphysematous cystitis and emphysematous cholecystitis. Radionuclide tests are decisive in the diagnosis and localisation of foot osteomyelitis, as well as the distinction of osteomyelitis from other conditions, notably Charcot osteoarthropathy. Technetium-99m methylene disphosphonate and labelled leukocyte bone scans are the main imaging techniques employed, while emerging techniques include single-photon emission tomography/computed tomography (CT) and positron emission tomography/CT. Nuclear medicine is also useful in the diagnosis and follow-up of specific infections in diabetes like, malignant external otitis, rhinocerebral mucormycosis, acute pyelonephritis, renal papillary necrosis and cholecystitis. The main indications of nuclear medicine tests are diabetic foot osteomyelitis, malignant external otitis, rhinocerebral mucormycosis and renal infections.
