We describe a case of acute appendicitis precipitated by human immunodeficiency virus-related Kaposi's sarcoma of the appendix. This presentation in an otherwise asymptomatic homosexual man led to the establishment of a diagnosis of acquired immunodeficiency syndrome. Immediate follow-up revealed multicentric gastrointestinal involvement by Kaposi's sarcoma, and skin involvement ensued in 2 months. Salient features of this case and two other similar reports in the literature are highlighted.

Nine patients known to have acquired immunodeficiency syndrome (AIDS) and/or human immunodeficiency virus (HIV) infection and operated on for acute appendicitis are presented. Six of the nine patients did not have an elevation in the white blood cell count preoperatively. Two patients underwent diagnostic laparoscopy prior to exploration. In four cases, a perforated appendix was removed. Seven patients had persistent postoperative fever, while all nine had a significant lack of leukocytosis after surgery. Other than the absence of a preoperative increase in white blood cell count, the presenting characteristics of this group were similar to those expected in immunocompetent patients. However, concern for a possible opportunistic infection etiology and a desire to avoid operating on these patients resulted in an undue delay prior to exploration. The use of diagnostic laparoscopy aided in earlier and more accurate diagnosis. Despite persistent postoperative fever, appendectomy was performed in patients with AIDS/HIV infection without significant increase in morbidity and mortality.

Many patients with acquired immune deficiency syndrome (AIDS) and abdominal pain are evaluated by the surgeon, and the majority have gastroenteritis, which can be treated with specific antimicrobials. There are some, however, who need more extensive investigation or who have an intra-abdominal infective process that requires surgical treatment. The one and a half decades of experience with human immunodeficiency virus (HIV) and AIDS has defined the role of the surgeon in treating patients with HIV. Major infective processes that may require surgical involvement include cytomegalovirus infection of the intestinal tract; appendicitis, which may be due to opportunistic infections; spontaneous bacterial peritonitis; cholecystitis; and obstructive jaundice with underlying sclerosis of the biliary tree. Early diagnosis and prompt surgical treatment are critical in the management of HIV-infected patients. For example, cytomegalovirus affecting the gastrointestinal tract may lead to perforation with the development of generalized fecal peritonitis; the clinical presentation of acute appendicitis in HIV patients may not include the usual rise in white blood cell count; and bacterial peritonitis in patients with AIDS may be caused by opportunistic pathogens or, as in the classical case, a single gram-negative bacillus or pneumococcus. This review article focuses on intra-abdominal infections in patients with HIV and AIDS.

The immune status was studied during the development of the disease in 182 children who were operated on for acute appendicitis. T lymphocytes and their subpopulations circulating in the blood, as well as B lymphocytes, immunoglobulins A, M, G, and immune complexes were determined. The character of changes of these values before the operation and in various postoperative periods were determined. The effect of complex treatment, including T-activin, on the clinical and immunological parameters in children with acute appendicitis was appraised. Analysis of the results showed that a transitory immunodepressive state forms in children with the disease, which is more marked in the destructive form, with normalization of the main values of cell-mediated and humoral immunity by the 7th day after appendectomy. In a complicated course of acute appendicitis the state of immunodeficiency is torpid in character and does not return to normal values even after clinical recovery, i.e. before discharge from the clinic. Inclusion of the immunostimulating agent T-activin into the complex treatment of patients with appendicitis ensures a more rapid involution of the main clinical manifestations of the disease. The therapeutic effect was most pronounced in destructive appendicitis: after 3 days of treatment the pain syndrome was encountered twice less frequently and intestinal paresis more than twice less frequently in these patients, and the term of hospital stay (8.8 +/- 0.4 days) was less shorter than for children of the control group (12.2 +/- 1.9 days) who did not receive T-activin in the therapeutic complex.

A case of abdominal mycobacterial infection mimicking acute appendicitis in a human immunodeficiency virus (HIV) infected patient is reported. The case illustrates the unusual aetiology of an acute abdomen in this population and the report reviews the aetiology of surgical abdominal pain in HIV infection and discusses the management of abdominal mycobacterial infections.

We report a case of chronic abdominal pain with subsequent development of acute right lower quadrant tenderness in a patient infected with the human immunodeficiency virus. Ultrasonography and computed tomography revealed an enlarged appendix. On subsequent laparotomy, the patient was found to have appendicitis due to cytomegalovirus. Six additional cases of this infection were identified in a review of the literature. The course of cytomegalovirus appendicitis in these patients was prolonged and atypical compared with noncompromised patients with acute appendicitis. Because perforation may occur, surgery is advocated when this diagnosis is suspected in the patient infected with human immunodeficiency virus.

Acute appendicitis rarely presents in the form or urinary tract symptoms. Atypical forms of acute appendicitis occur more frequently in subjects infected by the human immunodeficiency virus (HIV). The authors report a case of acute appendicitis in an HIV-infected subject mimicking acute pyelonephritis secondary to obstruction. Atypical forms of acute appendicitis must be diagnosed and treated as early as possible. Computed tomography plays an essential role in the diagnostic assessment of abdominal and lumbar symptoms in HIV-infected patients.
