[Hepatic changes in patients with isolated immunodeficiency virus infection and AIDS].

BACKGROUND: The aim of the present study was to describe the spectrum of liver disease in isolated infection by the human immunodeficiency virus and in the acquired immunodeficiency syndrome as well as evaluate whether clinical and/or biological data exist to permit specific diagnosis in liver biopsy. METHODS: Liver biopsy was performed in 39 patients with the human immunodeficiency virus (34 via parenteral drug addicts), 22 of whom had established acquired immunodeficiency syndrome. RESULTS: In 29 cases (74%) a specific histologic diagnosis was obtained with the changes most frequently found being the presence of granulomas (11 patients), mainly in patients with stablished AIDS, and chronic active hepatitis non A non B (10 patients), specially in the cases with isolated infection by the human immunodeficiency virus. Obtaining of a specific diagnosis was associated with an increase in GOT and a decrease of the CD4 lymphocytes and the CD4/CD8 quotient (p = 0.002 in all cases). The existence of established AIDS or prolonged fever was associated with the finding of hepatic granulomas (p = 0.02 and p = 0.002, respectively). The increase in GPT, the absence of stablished AIDS and the absence of prolonged fever was associated to the presence of chronic active hepatitis (p = 0.01, p = 0.002 and p = 0.0002, respectively). CONCLUSIONS: In patients with infection by the human immunodeficiency virus liver biopsy provides diagnostic information in a high percentage of cases. The presence of established AIDS, prolonged fever, and hypertransaminasemia may point towards possible histologic diagnosis.

Acute eosinophilic pneumonia due to toxocariasis with bronchoalveolar lavage findings.

A previously healthy young man presented with breathlessness, diffuse pulmonary infiltrates on the chest x-ray film, and a high degree of peripheral blood eosinophilia. Analysis of bronchoalveolar lavage (BAL) fluid showed 64 percent eosinophils. A diagnosis of toxocariasis was eventually reached on the basis of a positive enzyme-linked immunosorbent assay (ELISA) for Toxocara canis. The routine performance of the ELISA test for Toxocara in the diagnostic approach to pulmonary infiltration with eosinophilia could reveal an undetermined, sometimes unsuspected, number of cases of adult toxocariasis with pulmonary involvement. A high degree of eosinophilia in the differential cell count of BAL fluid may eventually prove to be a useful clue in favor of such a diagnosis.

[Kaposi's sarcoma with primary pulmonary involvement in a parenteral drug addict with acquired immunodeficiency syndrome].

Pulmonary Kaposi's sarcoma (KS) was diagnosed by pulmonary biopsy in a heterosexual parenteral drug abuser (PDA). The patient had previously been diagnosed of Pneumocystis carinii pneumonia and pulmonary tuberculosis. Thoracic computed tomography (CT) showed bilateral nodular lesions which were less apparent in conventional radiological study and which increased in size in spite of correct therapy. As cutaneous lesions suggesting KS subsequently appeared, the possibility of pulmonary KS was considered and confirmed by open biopsy. The rarity of a primarily pulmonary presentation of KS in a PDA, the difficulty in diagnosis owing to concomitant infective diseases and the diagnostic value of thoracic CT for the diagnosis of pulmonary KS are discussed.

Efficacy of octreotide in the management of chronic diarrhoea in AIDS.

Patients with HIV infection were studied to assess the efficacy of octreotide, a somatostatin analogue, in the long-term management of refractory diarrhoea. Dosage of subcutaneous octreotide was increased progressively at 48 h intervals from 150 to 300, 750 and 1500 micrograms/day according to response. Twenty-nine patients, 21 with Cryptosporidium enteritis, one with Isospora belli enteritis and seven with no identifiable pathogen were selected for the study; four of these were excluded from the study because of death during the first month (two cases), abdominal pain and acute pancreatitis (one case each). Twenty-five patients were evaluable for response. Ten patients (four with Cryptosporidium enteritis, five without an identifiable pathogen and one with I. belli enteritis) achieved a complete response (40%) and nine cases (all with cryptosporidial enteritis) had a partial response (36%). Patients with higher weight and Karnofsky performance status and non-cryptosporidial enteritis had a better response to treatment. Mean durations of treatment and response were 4.2 +/- 4.2 and 4.4 +/- 4.5 months, respectively. In the absence of specific agents for cryptosporidial enteritis and HIV enteropathy, octreotide was found to be useful in the management of chronic diarrhoea in AIDS patients.

Acute gastroduodenal lesions in patients with venous thromboembolism. Identification of patients at risk.

The prime complication of heparin therapy is bleeding, and the gastrointestinal tract is the most common site of bleeding in patients treated with heparin. We recently reported that gastroduodenal lesions are common in patients admitted because of acute venous thromboembolism, and now we present our experience in a larger series of patients. The aims of the study were to try to validate our previous findings and to identify clinical factors that could increase the likelihood of having an acute, potential bleeding lesion in the gastroduodenal tract. Upper gastrointestinal endoscopy was performed on admission in 155 consecutive patients with acute venous thromboembolism (118 with deep vein thrombosis, 37 with pulmonary embolism). Acute lesions (both peptic ulcers and diffuse erosions) were found in 19 of 118 patients (16 percent) with venous thrombosis, and in 14 of 37 patients (38 percent) with pulmonary embolism (p = 0.005). When only patients with pulmonary embolism were considered, lesions were more commonly found in men, and in patients with severe hypoxemia on admission. When considered overall, only the timing of endoscopy was statistically significant; acute lesions were more commonly found when endoscopy was performed early after admission. No significant differences were found in terms of age, sex, smoking habits, alcohol intake, concomitant drug ingestion, comorbid diseases, or previous history of ulcer. The very high incidence of upper GI tract lesions in these patients will have long-term diagnostic/therapeutic implications which cannot be ignored. Who should receive prophylactic H2 blockers and for how long remains to be determined.

[Athero-embolic nephropathy. Report of 2 cases].

Two cases of athero-embolic nephropathy unrelated with known precipitating factors such as aortic surgery, angiography, anticoagulation or pharmacological fibrinolysis are reported. In one, the histological study additionally disclosed endo-extracapillary proliferative glomerulonephritis. Hypocomplementemia or hypereosinophilia, which some authors consider very characteristic findings, could not be demonstrated in any of the two patients. The difficulties in the diagnosis of athero-embolic nephropathy and the possible indications of renal biopsy are discussed. Emphasis is made on prevention as the best approach to management, no specific treatment being available.
