We observed 12 patients with acute human immunodeficiency virus type 1 (HIV-1) infection. The clinical syndrome was characterized by fever (all cases), generalized lymphadenopathy (11), arthralgias and myalgias (9), sore throat (9), rash (7), splenomegaly (6), and other less frequent signs and symptoms. All patients had a spontaneous resolution of their symptoms within 5-30 days. Anti-HIV-1 serum antibodies, as measured by enzyme immunoassay (EIA) at the onset of clinical illness, were negative in every patient. HIV antigen (p24), on the contrary, was detectable in nine cases. Western blot IgM and IgG analysis was serially performed: IgMs were positive in nine cases and IgGs in three. The CD4+/CD8+ ratio was low in all patients because CD8+ were remarkably increased and CD4+ slightly reduced. A laterocervical lymph nodes biopsy was performed in four patients. The morphological and immunohistological pattern of the acute HIV-1-related lymphadenopathy did not correspond to any of the typical ones. The envelope virus protein gp120/160 was found in interfollicular and follicular lymphocytes, in endothelial cells, and in interdigitating and dendritic reticulum cells. The p17 and p24 core virus proteins were mainly detected in endothelial, interdigitating, and dendritic reticulum cells, but in only a few lymphocytes. The follow-up suggests a rapid evolution to ARC and AIDS in patients showing an acute symptomatic HIV infection.

The ultrasound findings of 58 patients with AIDS and ARC were analysed retrospectively. In 55% an enlarged liver, in 62% an enlarged spleen, partially with focal lesions, and in 21% enlarged abdominal lymph nodes were diagnosed. The typical focal segmental glomerulosclerosis of the kidney was observed in one case, and cholangitis in 2 patients. Abdominal ultrasound is the first diagnostic procedure to be performed in patients with AIDS and ARC when abdominal pathology is suspected. With US-guided thin needle puncture of the lesions, a histological verification of the pathologic findings is possible.

The ultrasonographic findings of 43 patients with AIDS and ARC were analyzed. In 63% an enlarged liver, in 66% an enlarged spleen, partially with focal lesions, and in 21% enlarged abdominal lymph nodes were diagnosed. The typical parenchymal lesions of the kidney (focal segmental glomerulosclerosis) were not observed. Abdominal ultrasound is the first diagnostic procedure to perform in patients with AIDS and ARC with the suspicion of abdominal pathology. With additional thin needle puncture of the lesions a histological verification of the pathologic findings is possible.

AIDS is frequently expressed through gastrointestinal o abdominal symptoms. In addition, patients with AIDS or ARC frequently have hepatic and biliary symptoms, while pancreatic alterations are found in 4-30% of patients hospitalised for AIDS. Since AIDS patients are immunodepressed, they are subject to opportunistic infection often multifocal and the pathological processes can be present simultaneously. About 2/3 of patients have enlarged liver, steatosis, splenomegaly, lymphoadenopathy, cholecystic and biliary tract abnormalities, alterations of liver function tests, and abdominal discomfort in the upper right quadrant. Jaundice is rare and hepatic failure is not common. Hepatic biopsy is often necessary to establish the diagnosis. The hepatic localisation of an opportunistic pathogenic agent is generally a sign of systemic dissemination which is expressed as granulomatous hepatitis (atypical mycobacteria, frequently mycobacterium avium, or M. tuberculosis representing the reactivation of latent diseases), peliosis hepatis, infection from CMV, HSV, EBV, Pneumocystis carinii, and mycotic infections. Coinfections with the hepatic virus (HBV, HDV, HCV) are also often present. Pharmacological damage may also be present (mainly caused by antibiotic therapies). Neoplasia are rare (hepatic Kaposi's sarcoma associated with cutaneous and gastrointestinal manifestations, or generally metastatic lymphoma). Damage of the biliary tract usually develops after other manifestations of the illness; the most frequent pictures are cholestatic syndromes and cholangitis, while cholecystitis and jaundice are rare. Pancreatic lesions are generally asymptomatic. They are diagnosed during autopsy and are caused principally by opportunistic agents.
