During 1983-1988, hospitalizations of patients with a diagnosis of human immunodeficiency virus (HIV) infection increased from 1.3 to 33.7 per 100,000 persons. We used the National Hospital Discharge Survey, which is based on a representative sample of discharges from nonfederal short-stay hospitals, to describe illnesses among hospitalized patients with HIV infection. Of 222,200 such hospitalizations during 1983-1988, most occurred among persons who were 25-44 years of age (79%), white (66%), and male (90%). Among men 25-44 years of age, HIV admissions increased from 8.5 to 148.6 per 100,000 persons during 1983-1988; among black men 25-44 years of age, HIV hospitalizations increased from 43.1 to 387.4 per 100,000 persons. Among women, hospitalizations increased 3.4-fold. Frequently listed illnesses in the Centers for Disease Control (CDC) AIDS case definition were Pneumocystis carinii pneumonia (30%), candidiasis (20%), and Kaposi's sarcoma (13%). Other frequently listed illnesses included infections (39%) such as pneumonia, sepsis, and urinary tract infections; blood dyscrasias (30%) such as anemia, thrombocytopenia, and agranulocytosis; metabolic (17%), gastrointestinal (16%), and respiratory disorders (12%); and drug abuse (9%). These data provide a minimum estimate of HIV hospitalizations because for some patients HIV infection may not be specified on the discharge record. HIV hospitalizations are increasing markedly and are associated with a broad spectrum of severe morbidity.

In a prospective study, we analysed the anorectal lesions observed in 148 human immunodeficiency virus-infected patients and compared the data with those reported in the literature. The majority of the patients (97.3%) were homosexual or bisexual men. The mean age of the population was 34.2 years. A history of previous sexually transmitted diseases was found in 79.7% of the male patients. The stage of HIV-related disease, according to the Centers for Disease Control classification, could be determined in 141 patients: 54.6% were stage II, 3.5% stage III and 41.8% stage IV. Anal condylomata were the most frequent manifestation, affecting 29.7% of the patients, 7.1% of whom showed moderate to severe dysplasia. The types were mainly 6, 11, 16 and 18, but types 31, 35 and 39 were also observed. Ulcerations were the most frequent non-condylomatous lesions, occurring in 41 patients; most (60%) were due to herpes viruses, and a large minority (21%) to cytomegalovirus. The etiology could not be determined in five cases. Anal sepsis was present in 11.4%, haemorrhoidal disease in 16.8% and fissures in 6%. Six patients developed Kaposi's sarcoma and seven, non-Hodgkin's lymphoma. No anal cancers were observed. Finally, wound healing was slowed in the patients operated on for haemorrhoids, fissures and suppuration. No statistical analysis could be performed because of the small number of patients.

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.

The majority of patients with Aids suffer from diarrhea and weight loss, as well as opportunistic infection and tumors of the gastrointestinal tract; endoscopy is frequently necessary. Often, but not always, it is possible to identify an opportunistic tumor or infection which explains the patient's signs and symptoms. In other cases, HIV may itself be pathogenic. The most important opportunistic pathogens are Candida albicans (stomatitis and esophagitis), cytomegalovirus and herpes simplex virus (esophagus, stomach, biliary system, colon), cryptosporidium (small intestine, biliary system), Isospora belli (small intestine), salmonella, shigella, and campylobacter (small and large intestine, septicemia), and Mycobacterium avium intracellulare (liver, spleen, intestinal submucosa, and bacteremia). Involvement of the gastrointestinal tract is frequent in Kaposi's sarcoma, though it is often asymptomatic. In contrast, gastrointestinal lymphomas are aggressive and rapidly progressive tumors.

Seventy-two and 34 consecutive HLA-identical sibling renal transplant recipients were treated with azathioprine/prednisone (AZA; follow-up, 5.0 years) and cyclosporine/prednisone (CSA; mean follow-up, 2.9 years), respectively. Both groups were similar in age, sex, race, and number of transplants, but there were more diabetics in the CSA group (34% v 8%). Actual patient survival at 1 year and actuarial patient survival at 5 years were 100% and 96%, respectively in the CSA group compared with an actual patient survival of 91% and 82% at 1 and 5 years, respectively, in the AZA group. Actual graft survival at 1 year improved from 85% in the AZA group to 97% in the CSA-treated recipients (P less than 0.05). Mean serum creatinine at 5 years remained stable in the AZA group at a mean of 123 mumol/L (1.4 mg/dL) compared with a progressive increase in this parameter to a mean of 212 mumol/L (2.4 mg/dL) after the same time interval in the CSA patients. Furthermore, the slopes of the serum creatinine against time were significantly different between the two groups (P less than 0.01). Mean daily CSA dose averaged 4 mg/kg 12 months following transplantation, with a decrease to 2.4 mg/kg by the fifth year. Causes of death in the AZA group were cardiovascular (eight), sepsis (three), cancer (one); and in the CSA group, Kaposi's sarcoma (one). Causes of graft failure in the AZA group were immunological (six), sepsis (three), technical (two), recurrence of disease (one), and patient death with a functioning graft (five). Technical (one), noncompliance (two), recurrence of disease (one), and patient death with a functioning kidney (one) caused graft failure in the CSA group. No difference in posttransplantation serum cholesterol or incidence of new onset diabetes was observed between the two groups, but hypertension was significantly more frequent (51% v 21%, P less than 0.01) when CSA was used. In conclusion, intermediate-term results of CSA-treated HLA-identical transplant recipients showed improved patient and graft survival with less complications apart from hypertension. However, the slow, but relentless, increase in serum creatinine in the CSA-treated patients compared with those treated with AZA is of concern.

During the past two decades, an explosive growth in both the prevalence and types of sexually transmitted diseases has occurred. Up to 55 percent of homosexual men with anorectal complaints have gonorrhea; 80 percent of the patients with syphilis are homosexuals. Chlamydia is found in 15 percent of asymptomatic homosexual men, and up to one third of homosexuals have active anorectal herpes simplex virus. In addition, a host of parasites, bacterial, viral, and protozoan are all rampant in the homosexual population. Furthermore, the global epidemic of AIDS has produced a plethora of colorectal manifestations. Acute cytomegalovirus ileocolitis is the most common indication for emergency abdominal surgery in the homosexual AIDS population. Along with cryptosporidia and isospora, the patient may present to the colorectal surgeon with bloody diarrhea and weight loss before the diagnosis of human immunodeficiency virus (HIV) disease. Other patients may present with colorectal Kaposi's sarcoma or anorectal lymphoma, and consequently will be found to have seropositivity for HIV. However, in addition to these protean manifestations, one third of patients with AIDS consult the colorectal surgeon with either condylomata acuminata, anorectal sepsis, or proctitis before the diagnosis of HIV disease. Although aggressive anorectal surgery is associated with reasonable surgical results in some asymptomatic HIV positive patients, the same procedures in AIDS (symptomatic HIV positive) patients will often be met with disastrous results. It is incumbent upon the surgeon, therefore, to recognize the manifestations of HIV disease and diagnose these conditions accordingly.

This review describes the transmission, clinical picture and immunological abnormalities of HIV infection in children in general, and the special problems of AIDS in African children. The review begins with a thorough introduction to the epidemiology of AIDS. Transmission to children generally involves vertical transmission by placental transfer or transmission of HIV via transfusion of blood and blood products, or by contaminated needles. Casual transfer is unknown, and only a few cases of transmission via breast milk are known. The clinical picture of HIV infection in infants and children differs from that in adults in 3 important aspects: earlier onset, different clinical presentation and existence of AIDS embryopathy. The average onset was 5 months of age. The most common symptoms in young children are chronic interstitial pneumonitis without demonstrable etiology, hepatomegaly, failure to thrive, adenopathy, diarrhea, oral or perineal thrush, eczema and thrombocytopenia. The common opportunistic infections are pneumocystis carinii pneumonia, cytomegalovirus, Epstein-Barr virus, Cryptosporidium diarrhea, pyogenic infections of the middle ear and gram-negative septicemia. Several infections seen in adult AIDS cases are rare in children: mycobacterium avium-intracellulare, toxoplasma gondii, hepatitis B, as well as Kaposi's sarcoma, malignant lymphoma and cardiac abnormalities. The AIDS embryopathy or HIV dysmorphic syndrome is characterized by immunological abnormalities, growth failure, and craniofacial dysmorphism, particularly microcephaly, prominent box-like forehead, hypertelorism, flattened nasal bridge, obliquity of the eyes, blue sclerae and patulous lips. AIDS in African children is extremely difficult to diagnose because of similarities between the presenting symptoms and those commonly seen in sick children there, many of whom are also immune compromised. Where serotesting is available, the picture is complicated by cross reaction between the test agents and some factor found in sera from malaria patients. Seropositivity in some areas is high, increased by the prevalence of transfusion and injection treatments. Diagnosis is made more difficult by lack of laboratory facilities and difficulties in follow-up for pediatric patients. The CDC definitions of AIDS and ARC, and the WHO/CDC definitions of AIDS are appended.

Thirty-six major abdominal operations were performed on 35 Acquired Immune Deficiency Syndrome (AIDS) patients (33 men, two women). Twenty-two elective operations were indicated for diagnosis of abdominal or retroperitoneal mass (6), incomplete bowel obstruction (5), intra-abdominal infection (4), biliary symptoms (3), thrombocytopenia (3), and toxic megacolon (1). Fourteen emergency operations were for perforated viscus or peritonitis (11), massive gastrointestinal bleeding (2), and cecal volvulus (1). In 5 of 22 (23%) elective operations AIDS was unknown to the treating physicians until diagnosed by the surgical pathology; in contrast, all 14 emergency operations were in patients who had a known diagnosis of AIDS. The operative findings were related to AIDS in 34 of 36 (94%) operations. Cytomegalovirus was the most common pathogen, isolated or identified microscopically in 11 patients (eight emergency and three elective operations). Mycobacterial infections presented as retroperitoneal adenopathy or splenic abscess in six patients. Non-Hodgkins lymphoma was the most common malignancy found, presenting as an abdominal mass (4), bowel obstruction (3), or with gastrointestinal bleeding (2). Kaposi's sarcoma was diagnosed at laparotomy in four patients. The 1-month operative mortality rate for elective operation was 9% (2 of 22) and 46% (6 of 13) in emergencies. Postoperative complications included 1 reoperation for sepsis caused by inadequately resected CMV colitis; 1 pancreatic fistula; 1 wound dehiscence, and 2 minor wound infections.

This retrospective study details the findings and outcome in 34 homosexual men, out of a total of 177 patients, who underwent surgery for non-condylomatous perianal disease over a 2-year period. Of 34 homosexuals 20 presented with anorectal sepsis compared with 11 of 79 heterosexual male patients (X2 = 24.07, P less than 0.001). Lesions included chronic intersphincteric abscess (eight patients), anal fistula (seven patients) and chronic intersphincteric abscess and fistula (five patients). Anal fissure occurred in 15 patients, anal ulcer in three, skin tags in six, haemorrhoids in two and Kaposi's sarcoma in one. Eight patients were human immunodeficiency virus (HIV) antibody negative, four were asymptomatic HIV antibody positive, 12 had symptomatic HIV infection using the Centers for Disease Control classification and in ten patients HIV status was unknown. Irrespective of the type of surgery performed, healing occurred within 6 weeks of operation in all HIV antibody negative patients, all asymptomatic HIV antibody positive and in only one of nine patients with symptomatic HIV infection. Eight of nine patients with symptomatic HIV infection failed to heal by this time (X2 = 8.98, P less than 0.05). These findings suggest that the prevalence of anorectal sepsis in homosexual men is high and that symptomatic HIV infection is an important determinant of progress after surgery.

A total artificial heart was used to support the circulation in 33 heart transplantation candidates who were expected to die before procurement of a donor heart. Twelve of these patients (mean age 35 +/- 10 years) underwent cardiac transplantation. Another patient is still being supported with the total artificial heart 90 days after implantation. The other 20 patients died during mechanical support because their condition could not be stabilized for transplantation, despite blood flow restoration. Fifty-six percent of the patients younger than 40 years underwent successful transplantation and six of nine patients are long-term survivors. By comparison, in the older group, 17.6% of patients underwent transplantation and one of three survived long term. Forty-four percent of patients in the acute decompensation group had successful transplantation and four of seven patients are long-term survivors. In the chronic decompensation group these figures were 29.4% and three of five patients. All patients who were heavily immunosuppressed (n = 4) died of sepsis. Transplantation was considered and performed only when the patient's condition was correct and stable. In six patients an infection developed in the immediate posttransplant period. Three of the infections were resolved with antibiotic therapy. One originated in the mediastinum and is still unresolved, although the patient's condition is improving. Another patient died of an anoxic coma caused by ventilatory problems. There were two late deaths at 14 and 19 months, one resulting from a combination of toxoplasmosis and rejection and the other from a Kaposi sarcoma caused by azathioprine treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
