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.

[Carcinoma of unknown origin. Diagnostic study of 48 cases and its clinical yield].

Forty-eight patients fulfilling the criteria for carcinoma of unknown origin (CUO) between April 1983 and December 1987 were retrospectively analyzed. Mean age was 62 (33-83). Twenty-seven were males (56%) and 21 females (44%). The most common site of metastasis was the bone (35%), followed by the liver (19%) and lymph nodes (19%). 58% of cases were adenocarcinomas. Overall 274 studies for the detection of the primary tumor were carried out, the diagnosis being achieved in 10 cases (3.65%) which corresponded to lung neoplasms (5 cases), prostatic adenocarcinoma with negative markers (2 cases), bile duct neoplasms (2 cases) and pancreatic carcinoma (1 case). In our series, the most useful studies were computed tomography (CT) and fibrobronchoscopy. The necropsy, carried out in 11 patients, yielded 8 additional diagnoses: pulmonary neoplasm (one case), gastric adenocarcinoma (2 cases), malignant melanoma (2 cases), small intestine neoplasm (one case), parotid cancer (one case) and hepatocarcinoma (one case). Thirty-five patients were treated with chemotherapy and/or radiation; 12 objective responses (3 complete and 9 partial) were achieved, with a median duration of the response of 10 months (range 0.2-78 +). In view of the low diagnostic yield of the studies in patients with CUO we feel that the diagnostic study may be limited to CT scan with evaluation of the possible usefulness of bronchoscopy in individual patients. Regarding therapy, it is to be noted that there was a tendency for a longer survival in patients who responded.

[Emergency endoscopic sclerosis in active hemorrhage caused by esophageal varices: analysis of 31 cases].

We have reviewed our experience in urgent endoscopic sclerosis of bleeding esophageal veins in most patients (67.7%) secondary to alcoholic liver cirrhosis. Through the flexible gastroscope, 1% of polydocanol was injected intra and periveinaly for sclerosis. Initial and primary hemostasis was achieved in 90.3% and 87% of the cases respectively. Hemorrhage recurred in 14.2% of the patients. Hospital mortality was 38.7% (11 patients classified in Childs group C and 1 patient in group B), although only 19.3% of the patients died because of esophageal vein bleeding. These results suggest that in a satisfactory percentage of cases urgent sclerosis of esophageal veins controls active bleeding, and the hospital mortality depends mainly on the severeness of liver failure in these patients.
