A number of distinct hematological alterations take place in the presence of infectious diseases. This review seeks to provide a diagnostic guide and prognostic criteria for the clinician in the light of the concomitant hematological changes occurring in course of acute and chronic viral, bacterial, spirochetal and protozoal infections. The authors emphasize the fact that although certain broad principles may be applied to each type of infection, these principles may have to be interpreted with considerable latitude in any individual case, on account of the variable factors of virulence and resistance. The careful examination of blood films and bone marrow smears, supplemented when appropriate by cytochemical reactions, may be useful in the differential diagnosis of various infective states and in assessing both the severity of the pathological condition and the response of the patient.

Levosulpiride in functional dyspepsia: a multicentric, double-blind, controlled trial.

Abnormalities in gastrointestinal motility have been reported in a substantial proportion of patients with functional dyspepsia, supporting the use of prokinetic drugs for treatment of dyspeptic symptoms. To evaluate efficacy and safety of levosulpiride in short-term treatment, 1298 patients were enrolled in a double-blind multicentric study carried out in 45 Italian Gastroenterology Departments. Patients were randomly assigned to either levosulpiride (25 mg tid), domperidone (10 mg tid), metoclopramide (10 mg tid) or placebo (1 tablet tid) for 4 weeks. Patients were selected on the basis of: a) occurrence in the last 4 weeks of at least 5/10 selected symptoms (anorexia, nausea, vomiting, upper abdominal pain, postprandial bloating, abdominal fullness, early satiety, belching, heartburn, regurgitation), severity of which should reach/exceed a total score of 8, as assessed by a specific scale ranging from 0 (absent) to 3 (severe); b) normal results of routine biochemical, ultrasound and endoscopic examinations. In addition, each patient subjectively evaluated efficacy of treatment by a visual analogue scale. Significant improvement was recorded for all symptoms at days 10 and 28 in all groups (p < 0.001), but levosulpiride was significantly (p < 0.01) superior to domperidone, metoclopramide and placebo both in the overall clinical improvement scale as well as in a subgroup of symptoms (postprandial bloating, epigastric pain, heartburn). Active treatments and placebo were comparable as far as concerns occurrence of side-effects (12-20%) including galactorrhoea, breast tenderness and menstrual changes.

Phase I-II study of dose intensified chemotherapy with filgrastim and thymopentin in patients with advanced cancer.

BACKGROUND: Carboplatin (CBDCA), cyclophosphamide (CTX) and etoposide (VP-16) combination chemotherapy is active in many tumors. A phase I-II study was designed in order to verify toxicity, maximum tolerated dose and activity of CBDCA, CTX and VP-16 given with Granulocyte Colony Stimulating Factor (G-CSF) and thymopentin (TP5), without bone marrow support. MATERIALS AND METHODS: A group of 12 heavily pretreated patients (PTS), 9 breast cancer, 2 small cell lung cancer and 1 gastric cancer, received fourteen courses of the described combination chemotherapy. Previous treatments were as follows: surgery in 10 PTS, radiotherapy in 7 PTS, chemotherapy in all PTS (median of 9 courses per patient). CBDCA, CTX, VP-16 were given over 3 days. CBDCA doses were calculated and expressed with the area under the concentration versus time curve (AUC). The dose range were as follows: CBDCA AUC 5.5-11 (400-800 mg/m2), CTX 1500-2500 mg/m2, VP-16 450-550 mg/m2, G-CSF was given 5 mg/kg/day from day 4 to day 17. TP5 was given, on alternate days, 1 mg/ kg from day 4 to day 30. RESULTS: 6 PTS developed fever > 38 degrees C for a median (M) duration of 4 days. 4 PTS required platelet support (M of 12 units) and 3 PTS red blood cells support (M of 2 units). Maximum tolerated dose was CBDCA AUC of 8, CTX 2000 mg/m2 and VP16500 mg/m2. No treatment related death occurred. Ten patients had responses and two had disease stabilisation. At the present time 5 PTS are alive and median overall survival is 13 months. CONCLUSIONS: These data indicate that dose intensified CT with the support of G-CSF and TP5 may be delivered safely and shows activity in heavily pre-treated patients.

Association between chronic lymphocytic leukaemia and secondary tumours: unusual occurrence of a neuroendocrine (Merkell cell) carcinoma.

The authors describe a case of cutaneous neuroendocrine (Merkell cell) carcinoma in a patient previously treated for Chronic Lymphocytic Leukaemia (CLL). The authors discuss some of the mechanisms concerning the increased frequency of a second tumour in patients with CLL and focus attention on the high incidence in CLL of secondary tumours, especially skin tumours, of which Merkell cell carcinoma is a rare example. The authors consider the possible therapeutic approaches, reported in the literature, for the treatment of this particular skin carcinoma, which on account of its aggressiveness and the preexistence of a leukaemic process requires a particularly careful therapeutic approach.
