From a total of 874 patients with small cell lung cancer (SCC), a series of 104 patients were reviewed to determine if bone marrow relapses are detectable by routine clinical investigations. Autopsy, including microscopical bone marrow examination, was performed in all the 104 patients and bone metastases were disclosed in 36 patients (35%). After retrospective evaluation it was concluded that dose modification, occurrence of leukopenia plus fever, need of blood transfusion, leukopenia, and thrombopenia during treatment all were without predictive value in the detection of bone marrow relapse. Increased concentrations of lactate dehydrogenase and alkaline phosphatase were, however, positively correlated to the finding of bone marrow relapse.

The purpose of this pilot study was to determine whether daily administration of cyclosporin A to symptomatic patients with primary biliary cirrhosis for 1 yr would lead to a significant and sustained improvement in liver enzyme abnormalities. Twelve adult patients (11 female, 1 male; aged 52.6 +/- 8.9 yr, mean +/- SD) with serologic and histologically defined primary biliary cirrhosis were randomized to receive either oral cyclosporin A or vehicle placebo. Cyclosporin A was administered at sufficient dosages to maintain serum radioimmunoassay trough levels between 100 and 200 ng/ml (starting dosage, 2.5 mg/kg.day). After 1 yr of therapy, significant changes from pretreatment values were seen only in recipients of cyclosporin A. These included a 37% decrease in mean serum alkaline phosphatase and a 43% decrease in gamma-glutamyltransferase (controls +3% and -14%, respectively). Mean serum bilirubin and albumin levels and prothrombin times remained unaltered in the two groups, as did the extent of inflammation and fibrosis and the histologic staging of liver biopsy specimens. Although mean serum creatinine levels increased by 51% in recipients of cyclosporin A (+2% in controls), there were no associated changes in diastolic blood pressure or creatinine clearance values. Other side effects including thrombocytopenia, hirsutism, headaches, tremor, and parasthesiae were common in the treated group but not of sufficient severity to warrant adjustment in the dosage or discontinuation of therapy. The observed changes in hepatic, renal, and hematologic tests tended to return to baseline after discontinuation of therapy. Two patients, both placebo recipients, died of liver failure during the study period. The results of this study indicate that in symptomatic primary biliary cirrhosis, cyclosporin A administration is associated with a significant improvement in cholestatic liver enzyme abnormalities that persists for the duration of therapy. A progressive rise in serum creatinine levels and a high incidence of side effects raise concerns regarding the long-term safety of this agent in primary biliary cirrhosis.

One hundred sixty-two patients with Stages III and IV non-Hodgkin's lymphoma of low-grade histologic type were treated with combination chemotherapy using cyclophosphamide, vincristine, and prednisolone (CVP) followed by radiotherapy to sites of previous bulk disease. The patients were randomized to receive either follow-up alone or "maintenance" chemotherapy with 2 years of intermittent chlorambucil. A complete remission was obtained in 56% of patients and the median survival was 64 months (median follow-up, 74 months). Multivariate analysis revealed stage (P less than 0.0001) and Karnofsky performance status (P = 0.021) to predict complete response (CR) and the achievement of a CR (P less than 0.0001), female sex (P = 0.008), the absence of bulk disease (P = 0.038) and low serum alkaline phosphatase (P = 0.002) to predict prolonged survival. The median relapse-free survival (RFS) of the complete responders was 41 months. A prolonged RFS was predicted by low stage (P = 0.014), low serum lactic dehydrogenase (LDH) (P = 0.045) levels, and by the administration of maintenance chlorambucil (P = 0.045). A prolonged survival of the complete responders was predicted by a low number of nodal sites of involvement with lymphoma at presentation (P = 0.022) and lack of liver involvement (P = 0.011). The administration of oral maintenance therapy with chlorambucil for a full 2 years was only possible in 38% of patients, mainly because of progression of disease and the induction of thrombocytopaenia, but despite this it prolonged the median RFS by 38 months and its use could be considered when future studies are being designed.

Bacillus piliformis infection (Tyzzer's disease) was diagnosed in a 7-year-old spayed dog that had icterus, hepatosplenomegaly, and polyuria. Hematology revealed regenerative anemia, leukocytosis, lymphopenia, and thrombocytopenia. Serum chemical analyses indicated hypocalcemia, high alkaline phosphatase activity, hypoalbuminemia, and hyperglobulinemia. At necropsy, the liver was stippled with gray-white focal lesions. Microscopically, the liver lesions were necrotic and inflammatory. Warthin-Starry-stained sections revealed rod-shaped bacteria in crisscrossing patterns characteristic of B piliformis. This dog was considerably older than dogs previously reported to have Tyzzer's disease and had a concurrent systemic hyphomycosis, suggesting it had been immunocompromised.

Aminoglutethimide (AG) and hydrocortisone (HC) were given to 20 patients with advanced prostatic cancer resistant to conventional hormonal therapy. Most patients had painful bone metastases and were heavily pretreated. 12 of 16 patients required narcotic analgetics. 8 of 20 were bedridden. AG + HC produced relief of bone pain in 12 patients (75%) and only 4 required narcotics after treatment. The performance status improved in 8 of 20 patients (40%). However, the number of bone metastases seen in bone scans decreased in only 4 patients (22%). The level of serum alkaline phosphatase decreased in 11 of 18 patients and that of acid phosphatase in 8 of 16 patients. The reduction of bone pain lasted approximately 4 months (range 1-15 months). The median lifespan between the start of AG treatment and death was 8 months (range 2-22 months). There was no difference in survival between responders and nonresponders. 3 patients had skin rash, 1 lethargy and 1 thrombocytopenia.

Five patients who developed acute renal failure due to acute tubular necrosis following multiple hornet (Vespa orientalis) stings are described. All of them had intravascular hemolysis. Evidence for rhabdomyolysis was present in 2 patients. Two patients had elevated transaminase and alkaline phosphatase levels and in 1 of these, liver biopsy showed centrilobular necrosis. Two patients had thrombocytopenia in the absence of disseminated intravascular coagulation. Two patients died of infections while the remaining 3 recovered completely. Acute renal failure following multiple hornet stings appears to result mainly from intravascular hemolysis or rhabdomyolysis although a direct nephrotoxic effect of venom cannot be excluded.

Chronic neutrophilic leukemia, which may be regarded a variant of myeloproliferative disease, is associated with mature peripheral neutrophilia, hepatosplenomegaly, tissue infiltration by mature and immature granulocytes, an elevated leucocyte alkaline phosphatase score, absence of the Ph1 chromosome and elevated vitamin B12. In the few cases described up to now thrombocytopenia and bleeding complications were frequently noticed. Here we describe two patients with chronic neutrophilic leukemia in whom thrombocytopenia and/or a profound defect of platelet function were the cause of death.

Adult cystic fibrosis (CF) patients are increasingly diagnosed with hepatic cirrhosis, cholecystitis, and cholelithiasis. A continuing diagnostic problem is the early detection of cirrhosis prior to diffuse liver involvement. Sonography has been used in evaluating the pancreas, gallbladder, liver, and spleen in cystic fibrosis patients. We used a real-time mechanical sector scanner to study the portal veins in adult CF patients randomly selected from our CF population and correlated the portal vein diameters with liver function studies. A measurement greater than 12 mm was interpreted as a probable sign of portal hypertension. Of 21 patients studied, 14 had portal veins that measured greater than 12 mm, and 12 patients had (although not necessarily at the time of the exam) elevated serum alkaline phosphatase levels. Three patients had associated splenomegaly and thrombocytopenia, and 10 patients also exhibited cholelithiasis and abnormal gallbladders on sonography. Initial results indicate that portal vein measurement may be a sensitive indicator of early portal hypertension. Sonography may, thus, isolate patients at high risk for possible future complications. Serial sonograms can be performed easily in evaluating the progress of liver disease.

We studied changes in peripheral blood and bone marrow biopsy specimens obtained before, during, and after recombinant alpha 2b-interferon (IFN-alpha 2b) therapy in 25 patients with hairy cell leukemia. During therapy, only 1 patient showed no improvement in at least one of the parameters monitored. Granulocytopenia, thrombocytopenia, and monocytopenia resolved in 19/20, 14/15, and 17/18 patients, respectively. In 18/21 patients with Hb less than 12g/dl before treatment, the anemia became less severe. Hairy cells disappeared or decreased in numbers in the peripheral blood in all patients. In the bone marrow, numbers of hairy cells decreased and numbers of granulocytic, erythroid, and megakaryocytic cells increased usually within 3-6 months after the start of therapy. In no patient were hairy cells ever completely absent from the bone marrow. After cessation of IFN-alpha, the median Hb value, WBC, and platelet counts changed little for up to 12 months, but the absolute neutrophil count and absolute monocyte count decreased. Hairy cells reappeared in the peripheral blood of three patients. In the bone marrow the percentage of hairy cells increased, whereas the percentage of granulocytic and erythroid cells decreased. Neutrophil alkaline phosphatase (NAP) scores were abnormally high in 18/18 patients studied prior to IFN-alpha, but became normal in 17 of these during therapy and were normal in seven first studied during therapy. The median NAP score doubled by 3 months after cessation of therapy and was abnormal in 17/19 patients followed for 6 months. NAP score may be useful in predicting changes in the bone marrow in patients treated with IFN-alpha. We did not find any parameter in the pretherapy specimens that would have allowed us to predict individual response.

Ten dogs were inoculated with Ehrlichia platys (E. platys) from an acutely infected dog. Two dogs were necropsied on each of days 7, 14, 21, 28, and 35 post-inoculation, and tissues were collected and either fixed in formalin or frozen for light microscopic examination of lesions or E. platys antigen localization in tissues. Serum antibody titers to E. platys and serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase activities were also determined. The significant light microscopic findings were lymph node follicular hyperplasia and crescent-shaped hemorrhages in the splenic periarteriolar lymphoid sheaths beginning day 7 post-inoculation. There was significant megakaryocyte hyperplasia of bone marrow on days 28 and 35 post-inoculation. Ehrlichia platys antigen was in macrophages at 14 days post-inoculation which corresponded to the initial decline in platelet numbers. Initial thrombocytopenia and splenic crescent-shaped hemorrhages were temporally related, however the degree of lesion development and prominence were not related to subsequent platelet numbers.
