[Diagnosis and prognosis of polymyalgia rheumatica and giant cell arteritis].

Retrospectively the data were examined of 69 patients with polymyalgia rheumatica (PMR) and giant-cell arteritis (GCA), of whom 62 were treated with corticosteroids. The clinical and laboratory data, and the outcome of temporal artery biopsy were compared. In addition the relation between the course of the disease and survival was investigated. PMR and GCA are closely related syndromes with a multiform clinical presentation. There even is a group of patients with merely systemic symptoms, without specific signs of PMR or GCA. Concerning the course of the disease patients can be divided into groups with a shorter and longer period of disease activity; patients with a smooth stable remission and a chronic disease. The former group shows a significantly better five-year survival. At the time of diagnosis no reliable prediction of the course of the disease is possible.

Effect of high-dose dexamethasone in prednisone-resistant autoimmune thrombocytopenic purpura (ITP).

This study investigated whether high-dose dexamethasone pulse therapy could bring about a remission in adult chronic idiopathic thrombocytopenic purpura (ITP) patients who had not achieved a remission on the usual prednisone therapy. Newly diagnosed patients with ITP received the usual prednisone therapy, 1 mg/kg/day, for 3 weeks, after which period the dosage was tapered off. If after 6 weeks of treatment the platelets were less than 50 x 10(9)/l the prednisone therapy was considered a failure and 200 mg dexamethasone i.v. was given on 3 consecutive days. Six of the twenty-five patients with newly diagnosed ITP treated according to this protocol achieved a sufficient response with prednisone therapy. Nineteen patients were resistant to or relapsed during prednisone therapy and were treated with high-dose dexamethasone. Four of these nineteen patients showed a sufficient response. Three are still in remission. As no serious adverse effects were observed, high-dose dexamethasone therapy can be considered before splenectomy in prednisone- resistant ITP patients.

Scalp cooling by cold air for the prevention of chemotherapy-induced alopecia.

A new system is described for cooling the scalp with cold air in order to prevent chemotherapy-induced alopecia. Compressed air was cooled by means of a vortex tube built into a hair-drier cap. This system reduced the blood flow in the scalp to 35%, the surface temperature to 14.2 degrees C and the intradermal temperature at hair follicle level to 29.2 degrees C. The low temperature could be kept constant for at least one hour of cooling. By means of comparison, with cryogel packs the lowest epidermal temperature attained was 17.9 degrees C; moreover, once this was reached after 10 min, it rapidly rose again to 20.6 degrees C after 40 min. Forty-eight patients receiving cytostatic treatment for breast cancer were subjected to scalp cooling with the cold air system, starting 15 min before chemotherapy and lasting for 90 min. With the system set at an air temperature of -12 degrees C, the treatment was well tolerated. Of the 13 patients treated with 40 mg/m2 doxorubicin in combination with other cytostatics, 6 had hair loss less than WHO grade 3, in contrast to 1 of 4 patients given cryogel packs. However, patients treated with epirubicin at 75 mg/m2 all showed grade 3 hair loss in spite of air cooling. In view of the possibility of achieving and maintaining low scalp temperatures, the cold air system is to be preferred to cryogel packs. Whether better clinical results may be obtained with cooling for longer periods and/or to lower temperatures remains to be determined.

Phase II trial of 5-fluorouracil, adriamycin and cisplatin (FAP) in advanced gastric cancer.

Twenty patients (15 male, 5 female) with nonresectable gastric adenocarcinoma were treated with FAP (5-fluorouracil 300 mg/m2 IV on days 1-5, adriamycin 50 mg/m2 IV on day 1, cisplatin 20 mg/m2 IV on days 1-5). Each course was repeated every 21 days. Eighteen patients were evaluable for response. The median age was 51 years, the range extending from 34 to 68. None had undergone chemotherapy. The median Karnofsky performance score was 80%. Nine (50%) partial responses (PR) and eight (44%) cases of stable disease (SD) were observed. One patient showed progression of the disease and died after 6 months. The median duration of response was 6+ months for PR and 6 months for SD. The median survival was 12 months. FAP toxicity was moderate, with the median WBC nadir 3.2 X 10(9)/l (range 0.7-4.2). One patient in PR died of septicemia. Nausea and vomiting were not dose-limiting. Neuropathy was mild in four and moderate in two patients. This FAP combination appears to be as effective with respect to response rate and duration as reported for 5-fluorouracil, adriamycin and mitomycin C (FAM).

The absence of influence of acetylsalicylic acid (ASA) on the transient decrease in platelet counts observed after infusion of bleomycin and vinblastine.

Retrospectively we observed an early-onset transient decrease in platelet counts in a group of patients treated with cisplatin, vinblastine and bleomycin. Though less pronounced, the decrease was also found in a prospectively studied group of patients treated with bleomycin, etoposide and cisplatin, but was absent after treatment with etoposide ad cisplatin. In a randomized cross-over study acetylsalicylic acid (ASA) appeared not to prevent the drop in platelet counts. Bleomycin appears to induce an early-onset transient decrease in platelet numbers, possibly by direct or indirect platelet lysis. Vinblastine may have a synergistic effect to this phenomenon.

Interrelationship of immunologic characteristics, proliferation pattern, and prednisone sensitivity in acute lymphoblastic leukemia of childhood.

In children with acute lymphoblastic leukemia (ALL) the effect of prednisone therapy on the cell-cycle phase distribution of leukemic bone marrow cells was determined with pulse cytophotometry at the time of diagnosis. Also, the interrelationship with the presence of the sheep erythrocyte receptor as a marker for T cells was investigated. In 17 or 21 patients prednisone treatment caused a decrease in the percentage of cells in the S+G2+M phases. In 11 of 12 adult patients with ALL the same result was obtained. In a group of 31 children with ALL, 6 cases of T-cell ALL occurred in combination with intermediate or high WBC counts. The 3 patients with the highest E-rosetting percentages had rather high proportions of bone marrow cells in the S+G2+M phases. No correlation could be established between the WBC count or the E-rosetting percentage and the chance for complete remission.

Proliferation of leukemic blood cells in short-term liquid cultures. Relevance to the differential diagnosis of acute myeloblastic and lymphoblastic leukemia.

In short-term liquid cultures of leukemic blood cells from 60 untreated patients with acute lymphoblastic leukemia (ALL) or acute myeloblastic leukemia (AML) the 3H-thymidine incorporation was measured. After 24, 48 and 72 h of culture, leukemic cells from AML patients consistently showed much higher incorporation values than those from ALL patients. In addition, the cultured cells were studied with the pulse cytophotometer to measure the cell phase distribution of the leukemic cell population. The percentages of cells in S, G2, and M phases in cultures from AML patients were also clearly higher than those from ALL patients. These test methods provide an additional diagnostic aid, especially for those forms of acute leukemia, which remain unclassified by conventional morphological and histochemical criteria.
