Acalculous cholecystitis, a recognized manifestation of acquired immune deficiency syndrome (AIDS), causes abdominal pain which can be relieved by cholecystectomy. The indications for cholecystectomy have remained undefined, however, because the cholecystitis is usually accompanied by generalized cholangitis and it is difficult to distinguish the relative clinical importance of the two problems. Since 1985, we have performed cholecystectomy on 8 patients with AIDS who had clinical manifestations of acute cholecystitis associated with a thickening of the gallbladder wall by 5 mm to 12 mm. Two of the 8 had gallstones and 4 had associated cholangitis. All had been treated with antibiotics for 20 to 180 days before surgery, but physical deterioration had progressed in every case. At the moment of surgical intervention, 4 patients had multiple organ failure. One patient died 3 days postoperatively, but the rest recovered rapidly with resolution of the abdominal pain and sepsis. Two patients died 20 days after surgery due to complications of AIDS. The remaining 5 died due to AIDS at 6, 9, 10, 12, and 14 months after surgery. Two of this group developed progressive cholangitis with raised serum alkaline phosphatase. Our experience indicates that cholecystectomy should be considered for the treatment of severe and persistent symptoms of hepatobiliary manifestations of AIDS notwithstanding the presence of cholangitis.

Both AIDS-related infections and neoplasms of the gastrointestinal tract may be manifest by a clinical picture of acute abdominal disease. Severe abdominal pain may be seen in this population even in the absence of true surgical complications such as perforation, abscess formation, or obstruction. Localizing signs and symptoms are frequently misleading due to underlying immunosuppression, debilitation, and prior or current antibiotic use. CT assumes a critical role in evaluation of the symptomatic AIDS patient, providing evaluation of the entire abdomen and pelvis including lymph nodes, solid viscera, and the bowel itself. CT is thus the modality of choice for characterization of AIDS-related abdominal disease and for direction of appropriate therapy.

Infection due to the Mycobacterium avium complex (MAC) is the most common opportunistic disease of bacterial origin among patients with AIDS in the United States. The incidence of disseminated disease due to MAC (DMAC) has risen dramatically in recent years. The risk of developing DMAC increases as the CD4+ lymphocyte count declines to < 100/mm3. Preliminary analyses of several studies suggest that gender, racial or ethnic group, and individual risk factors for human immunodeficiency virus infection do not influence the incidence of DMAC but that prior Pneumocystis carinii pneumonia, the development of severe anemia, or the interruption of antiretroviral therapy may increase risk. Both the respiratory and the gastrointestinal tracts probably serve as portals of entry for MAC. Colonization may potentiate the risk of DMAC but does not always precede dissemination. Patients with AIDS and DMAC have a shorter duration of survival than do those with AIDS but without DMAC. While treatment for DMAC may extend survival, no well-controlled, prospective, randomized clinical trial has documented this point. Most patients with AIDS and DMAC have disseminated multiorgan disease; the most frequently described symptoms include fever, night sweats, weight loss or wasting, diarrhea, and abdominal pain. The most commonly identified laboratory abnormalities are anemia and elevated serum levels of alkaline phosphatase. Localized disease syndromes related to MAC infection occur less often.

Abdominal infections or tumors in the immunocompromised host are both common in AIDS but uncommon in transplant recipients. The role of diagnostic imaging modalities differs in the patients with specific symptoms such as dysphagia, diarrhea, malabsorption and jaundice and in the patients with aspecific clinical findings such as fever, weight loss, superficial lymphadenopathies and abdominal pain. In the former patients, the symptoms suggest a disease of one or more alimentary tracts, in which case radiology is ancillary to clinics and endoscopy plays the leading role to make the diagnosis. However, X-ray barium studies yield valuable information on different types of infections--e.g., Candida, Cytomegalovirus, mycobacterium avium intracellulare and Cryptococcus infections--in Kaposi's sarcoma and in gastrointestinal lymphoma. In these cases CT findings may suggest the diagnosis. In the patients with aspecific findings, US, as an easy immediate examination, and CT, as a panoramic means, can demonstrate deep lymphadenopathies and focal parenchymal lesions which are sometimes suspected to be abscesses or tumors. Moreover, both methods can provide indications and guide to percutaneous needle biopsies. Especially CT findings can distinguish mycobacterial infections from neoplastic lesions on the basis of the involved anatomical sites and of densitometric features. US and CT are useful means to monitor HIV+ subjects, to manage AIDS patients and to follow-up transplant recipients.

Bacillary angiomatosis is a newly characterized infectious disease occurring mainly in patients with AIDS. Most patients have cutaneous angiomatosis lesions resembling Kaposi's sarcoma or pyogenic granuloma. Although the disease may be life-threatening if not treated, it is curable with appropriate antibiotic therapy. A patient had a fever, nightsweats, abdominal pain, pleural effusions, and asymmetric peripheral lymphadenopathy. Computed tomography of the chest and abdomen revealed a unique pattern of enhancement of lymph nodes that, to this research team's knowledge, has not been reported previously with this condition. Appropriate antibiotic therapy resulted in a complete resolution of the disease. Included is a discussion of the clinical presentation, etiology, histology, and treatment of bacillary angiomatosis.

Abdominal pain and fever in patients with the acquired immunodeficiency syndrome (AIDS) may indicate cytomegaloviral (CMV) acalculous cholecystitis. We reviewed clinical, laboratory, and outcome data from 12 patients with CMV cholecystitis. Ten of 12 patients were homosexual males. Six patients had markedly low CD4: CD8 lymphocyte count ratios. Total leukocyte counts were normal or decreased, serum liver function tests normal or cholestatic, and only one patient had hyperbilirubinemia. Sonographic transmural gallbladder edema is typically more severe than expected for the presenting illness. Five of six patients investigated with HIDA scintigraphy had a nonvisualizing gallbladder. Open cholecystectomy had a 9.1 per cent operative morbidity and a 0 per cent mortality. Cholecystectomy is a safe and curative intervention, regardless of the immunocompromised condition of the host. Intraoperative cholangiography will identify papillary stenosis or sclerotic bile ducts as a potential cause of recurrent symptoms following surgery. A search for other sites of tissue invasion by CMV should follow cholecystectomy.

Surgeons throughout the country are frequently asked to consult on acquired immunodeficiency syndrome (AIDS) and human immunodeficiency virus (HIV)-infected patients experiencing abdominal pain. Disease processes vary remarkably within this population and often occur with confusing presentations and unusual pathologies related to the immunocompromised state. With the increased awareness and treatment of HIV infection, it can be anticipated that many patients will require surgery for secondary complications of AIDS, in addition to surgical problems unrelated to HIV infection. Twenty-five patients diagnosed with HIV infection underwent major abdominal surgery between 1986 and 1990 at The Mount Sinai Medical Center. Those patients classified as having AIDS had a longer post procedure hospitalization (19 days vs 9 days; P < 0.05) and a higher mortality rate (33% vs 10%). All of the patients who underwent appendectomy survived with few complications. Excluding appendectomy patients, operative mortality was predicted by low serum albumin (P < 0.001). In addition, preoperative hematocrits were considerably lower in non-survivors. Total serum protein and total WBC counts were not predictors of operative outcome.

Discussion of pain problems in persons with AIDS has been limited in medical and nursing literature, yet pain is a major source of suffering and concern for patients. Common pain characteristics are described in 100 persons with CDC-defined AIDS, using the 1987 definition. The two most frequently cited types of pain for both drugs users and nondrug users with AIDS were abdominal pain and neuropathic pain. Drug users experienced pain due to esophagitis and headaches more frequently than nondrug users, while nondrug users experienced Kaposi's sarcoma-related pain more often. Treatment responses were individualized, with drug users requiring more frequent use of opiates. General treatment strategies are suggested with special emphasis on the unique needs of PWAs.

A case control study of AIDS related sclerosing cholangitis indicates that it has no overall influence on prognosis, but is responsible for a striking reversal of the usual inverse correlation of age and survival in HIV infection. Pain, the principal symptom, was controlled in surviving patients with analgesics alone. Twenty consecutive patients with AIDS related sclerosing cholangitis, defined from at least two characteristic lesions at endoscopic retrograde cholangiopancreatography, were followed for a minimum of 10 months or until death. Median age was 33.5 years (range 27-50). All had abdominal pain; 11 had diarrhoea. Alkaline phosphatase was > 2X normal in 13, but the bilirubin was raised in only three. The median CD4 was 0.024 x 10(9)/l (0.005-0.341). Thirteen had cryptosporidiosis, six had active cytomegalovirus, five had no gastrointestinal pathogen. Three patients are alive without AIDS related sclerosing cholangitis symptoms at 10, 11, and 21 months. Seventeen have died at median 7 (1-23) months. Cytomegalovirus therapy had no apparent influence. The initial CD4 was < 0.11 in all those dying within six months, but correlation of CD4 with prognosis was otherwise poor. Controls, matched for age, CD4, and opportunistic infections had virtually identical overall outcome (median survival 7.5 months) and the expected worse prognosis with increasing age. Increasing age, however, appeared protective in AIDS related sclerosing cholangitis (r = +0.6; p < 0.05): this is not explained by disproportionate degrees of immunosuppression, nor by opportunistic infections.

One hundred and fifty-one patients intolerant to zidovudine (AZT) received didanosine (ddI) to a maximum dose of 12.5 mg/kg/day. Patient response was assessed using changes in CD4+ lymphocyte subset count, HIV p24 antigen, weight, and quality of life. Seventy patients developed major opportunistic infections whilst on therapy; this was the first AIDS diagnosis in 17. Only minor changes in CD4+ lymphocyte subset count were observed in AIDS patients, although a more significant rise occurred in those with earlier stages of disease. Of those positive for p24 antigen at the commencement of the study 67% showed a positive response, and this was most likely in those with CD4+ lymphocyte subset counts above 100 mm3. A positive weight response was seen in 16% of patients. Most patients showed improvement in individual parameters and global score of quality of life. Adverse reactions possibly attributable to didanosine were common. The most common side-effect was diarrhoea, which resulted in cessation of therapy in 19 individuals. Peripheral neuropathy occurred in 12 patients and pancreatitis in six. Thirteen patients developed a raised serum amylase without abdominal pain. Seven patients developed glucose tolerance curves characteristic of diabetes but these were mild, did not require treatment and returned to normal on ceasing didanosine.
