RESUMO

Since 2005, registers of patients treated with Thromboreductin (anagrelid) kept by some centres in the Czech Republic have been supplied with data concerning patients whose treatment with this preparation started in 2004. The purpose of the register is to record responses to therapy by Thromboreductin and adverse events in patients with essential thrombocytemia and other myeloproliferations, and to subsequently analyse the data. Another objective is to detect predisposition to clinical symptomatology and disease complications. Apart from thrombocyte count, additional risk factors are monitored. The database currently contains data for 336 patients. Initial analyses of data from the register point to the fact that anagrelid is a highly effective thromboreductive agent the administration of which is associated with relatively low incidence of adverse events (11.8 %) of mild and usually transitory nature. The therapeutic objective is attained at a relatively slow rate (according to overall stratification under 400 or under 600 x 10(9)/l thrombocytes), which is probably due to insufficient dose adjustment.

RESUMO

Anagrelide hydrochloride is an effective drug used in patients with ET and other myeloproliferative disorders with thrombocythemia to selectively decrease the number of thrombocytes. Indications for use of anagrelide were described in detail in Czech medical literature. Since 2005 data concerning treatment with anagrelide in some medical clinics have been collected in patient register showing course of treatment from 2004, when the medicament obtained marketing authorization from State Institute for Drug Control to be used in the treatment of thrombocythemia in myeloproliferative disorders. Aim of patient register is to monitor medical effect of anagrelide therapy and incidence of adverse effects in patients with ET and other myeloproliferative disorders and subsequent analysis of collected data. At the moment patient register contains data from 154 patients.

RESUMO

OBJECTIVE: The objective of the investigation is evaluation of therapeutic results and the development of the prognosis of patients with multiple myeloma (MM) as a result of consecutive changes of therapeutic procedures in patients of central and northern Moravia in the course of the last 40 years. METHODS AND RESULTS: The analyzed group of 562 patients with MM was concentrated at the Ist and IIIrd Medical Clinic of the Faculty Hospital Olomouc in 1959 - 2000, median age 63 (28-91) male/female ratio 1.1: 1.0. From analysis of Kaplan-Meier survival curves and the results of statistical analysis (log rank test p = 0.0000) ensued that during the evaulated period a very substantial change of prognosis occurred with improvement of theraupeutic results and a significant prolongation of survival in general. The first " turning point" was the introduction of chemotheraphy with alkylating substances with Prednisone (1963-1975), leading as compared with the period of symptomatic treatment alone (1959-1063) to a significant prolongation of the media value of general survival (M) from 8 to 19 months (p = 0.0031) and 3-year survival from 4 to 23 % patients, whereby 10-year survival was only 0 % and 1 %. The second "turning point" was the period from 1976 - 1980 with introduction of systematic chemotherapy using conventional doses of polychemotherapeutic (CP) regimes with better opportunities of supporting treatment (M = 40 months, p = 0.0000; 3-year and 10-year survival 55% and 5.5% patients). The therapeutic results acheived during the subsequent 15 years were however an unsatisfactory advance. During the interval between 1976-1995 in a group of 295 patients divided into 5-year sub-periods remission was acheived (R = < 25 % of the baseline value of M-protein) in 10-24 % patients, an inadequate response (NR) = persistence in > 50 % M-protein) in 55-28 %, prolongation of the median of total survival in 232 of the accessble patients for 44 months and long-term survival of 5 - 10 years after establisment of the diagnosis increased from 25 to 36 % and from 5.5 to 16.5 % patients. The third "turning point" was 1996 characterized by the introduction of high-dosage chemotheraphy with transplantation of autologuos peripheral haematopoietic cells ("HD" therapy with ASCT) leading ina group of so far only 33, assessable patients under 65 years to acheived remission in 71 %, to decline of NR in 10 % only and 5 -year suvival so far in 91 % patients ( p = 0.0037). Improvement of therapeutic results and prognosis of the disease as compared with 1976 - 1995 occurred in the whole group of patients also in 1996 - 2000 (CP and "HD"-therapy with ASCT) characterized by remission in 36 %, NR IN 33 % and 5 -year survival in 57 % (p = 0.030). It was reveled that the application of "HD" theraphy with ASCT led in 1995-2000 to the acheivement of more favorable therapeutic results (R - 71 % NR - 10 %. 5-year survival after the interval which elapsed so far 91 %), as compared with 2 similar groups of subjects under 65 years meeting the criteria of "HD" theraphy with ASCT, but treated only by conventional polychemotheraphy (1991 - 1995 and 1996 - 2000: R - 24 and 32 %, NR - 42 and 23 %, 5-year survival 46 and 68 % of the patients). In the group of 148 patients from the period of 1991-2000 the patients had as regards remission (R) more favourable results as compared with patients with NR concerning the prognosis [M 63 vs.22 months, 5-year and 10-year survival 53 vs. 17 % and 17 vs. 0 % of patients (p = 0.0000)]. CONCLUSION: From the submitted analysis ensured that during the period form 1959 - 2000 in patients with mutiple myeloma in central and northern Moravia as a result of the application of modern methods of chemotheraphy and supporting treatment a significant improvements of results of conventional treatment occurred with a more than 5 fold prolongation of so far assessable median values of survival (8 - 44 months) and long-term 10-year survival of almost one sixth of the patients. The real asset of "HD" theraphy with transplantation of ASCT will be revealed by analyses made after a longer time interval.

RESUMO

Questionnaires on the quality of life and tolerance of different parts of maintenance treatment were sent to a total of 83 patients with multiple myeloma. All patients were for more than one year on maintenance treatment which involved either interferon alpha monotherapy (I), 3 million u. three times per week till signs of relapse developed or sequence administration of interferon alpha and dexamethazone 40 mg on day 1 to 4, 10 to 13 and 20 to 23 and then after a four-week interval again interferon alpha, again till progression of the disease occurred. The patients evaluated the presence or absence of different undesirable effects of treatment during the first two weeks of treatment and throughout the year and listed their intensity into four categories defined in the questionnaire. The quality of life was evaluated by means of a basic module of the questionnaire of the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire version 3.0 (EORTC QLQ-C30). The results of the questionnaire are to a certain extent surprising as from the patients' answers ensues that this maintenance treatment is associated with more numerous undesirable effects than the physicians realized when in contact with the patient. In this summary we can list only the most frequent effects (deterioration of eyesight, impaired sleep, depressions, irritability and unrest, chill, pain in muscles and joints, general weakness and dyspnoea). From the questionnaires on the quality of life ensues a markedly poorer quality of life of these patients as compared with the healthy population. There are however no basic differences between individual groups. The questionnaires were handed only to patients who had maintenance treatment for more than one year and thus patients were eliminated where maintenance treatment was discontinued because of undesirable effects. To give a general idea of the tolerance of the above maintenance treatment the authors mention that to the date of Aug. 31, 2001 113 patients were randomized into one of the branches of maintenance treatment. Maintenance treatment had to be discontinued in 6% patients (in two instances on account of severe hypothyroidism, in one case on account of hallucinations, in three instances on account of severe mental depression caused by this treatment). Reduction of interferon doses in 20% patients usually because of cytopenia but also on account of psychic problem. To the question what length of prolongation of life compensates the undesirable effects of maintenance treatment the following replies were obtained from patients receiving ID, possibly I: 3 months--47.6 and 38.3%, 6 months--4.3 and 10.6%, 9 months--0 and 4.3%, 12 months--47.6 and 46.8% of the addressed patients. In reply to the question whether the patients would prefer, assuming equal effectiveness, a maintenance monotherapy with interferon alpha or dexamethazone more patients preferred interferon to dexamethasone. For practice ensues from this article informing on undesirable effects of maintenance treatment and the effect of maintenance treatment on the quality of life: 1. the necessity of thorough knowledge of physicians of all possible undesirable effects as only a doctor knowing possible undesirable effects of treatment can recognize them, 2. regular monitoring not only of the activity of the basic disease, but also undesirable effects of maintenance treatment and the influence of treatment on the patients' quality of life, 3. the necessity to assess the quality of life in clinical trials as an important parameter for deciding on the way of treatment.

RESUMO

In the clinical 4W study patients with newly diagnosed multiple myeloma are included where the state of the disease calls for treatment, while high dose chemotherapy is not contraindicated. Treatment according to protocol 4W comprises induction chemotherapy VAD, mobilization of haematopoietic cells (cyclophosphamide 5 g/m2). This is followed by autologous transplantation (as a conditioning regime melfalan 200 mg/m2 is administered). The patients are randomized into two groups, the first one is given interferon alpha as maintenance treatment, in the second group alternates cyclically interferon alpha and dexamethasone treatment. So far between 1996 and Aug. 31 2000 in the 4W clinical study 167 patients were included. 113 patients after transplantation were evaluated incl. 13 (12%) who achieved complete remission of the disease (absence of paraprotein, negative immunofixation), 63 patients (56%) with remission of the disease (decline of paraprotein, by more than 75%). Another 24 patients (21%) achieved partial remission (decline of paraprotein by more than 50% but less than 75%). The peritransplantation mortality is 2.67%. So far there is no significant difference between the two groups on maintenance treatment as regards the mean period before a relapse of the disease (p = 0.567). The median of the mean survival was not reached so far. The authors describe the results of the internal analysis of data incl. statistical processing.

RESUMO

In a group of 85 patients with multiple myeloma (MM) incl. 50 patients examined at the time when the diagnosis was established the relationship of the values of the propidium-iodide index (PI index) of myeloma plasmocytes of the patients were examined by flow cytometry using the double staining method, and selected laboratory parameters of the disease were analyzed. It was revealed that the values of the PI index examined with the aid of different "identification" monoclonal antibodies did not differ significantly. The median and average value of the PI index was in the whole group for PI/CD38 2.3 and 2.3%, for PI "UHKT" 1.8 and 1.8% and for PI/B-B4(CD138) 2.2 and 2.4%. In the group of patients examined at the time when the diagnosis of MM was established before chemotherapy the median and average value of the PI/CD38 index was 2.0 and 2.2%, PI/"UHKT" was 1.5 and 1.6%, PI/B-B4 (CD138) 2.6 and 2.5%. In the two analyzed groups no statistically significant correlations of PI/CD38,/"UHKT" and B-B4(CD138) index were found with the number of granulocytes, thrombocytes, immunochemical type and the value of the serum M-component, and levels of S-beta 2 microglobulin, S-urea, S-creatinine, S-calcium, and S-lactic dehydrogenase. A significant positive correlation was found in both groups with the level of S-thymidine kinase, in the whole group of indexes PI/CD38 and PI/B-B4(CD138) with the severity of anaemia, index PI/CD38 correlated with S-albumin and index PI/B-B4(CD138) with the percentage ratio of plasmocytes in bone marrow. It was revealed that examination of the propidium-iodide index is a suitable and prompt method for evaluation of proliferative properties of the myeloma population.

RESUMO

We report our results with high-dose chemotherapy in previously untreated multiple myeloma patients (4 courses of VAD chemotherapy, collection of PBSC after priming with cyclophosphamide, 5 g/m2, high-dose chemotherapy with melphalan, 200 mg/m2). Second transplantation was indicated only for patients who did not achieve remission after the first high-dose therapy (paraprotein lower than 25% of the pretreatment value). For the second transplantation melphalan (200 mg/m2) with methylprednisolone (1.5 g for 5 days) were used as conditioning regimen. After high-dose therapy all patients were randomized into two arms of maintenance therapy: interferon alpha-2b or sequential maintenance therapy (interferon alpha-2b for 3 months followed after 4 week pause by 40 mg of dexamethasone days 1-4, 10-13 and 20-23. The administration of interferon alpha was resumed four weeks after the last dexamethasone for next three months. The maintenance therapy continued for 48 months or until the progression. Fifty-five patients were enrolled in the study from January 1996 to August 1997. Thirty-five patients have undergone the first transplantation and 57% of them reached complete remission. There were 10% of non-responders after the first high-dose regimen. The mean time to reach white blood cell count above 1 x 10(9)/L after the application of high dose melphalan and platelets more than 50 x 10(9)/L were 12.2 (range 6-16 days) and 12.4 (range 0-25 days), respectively. Grade 4 mucositis according to SWOG classification requiring total parenteral nutrition was presented in 40% of the patients. The mean number of 1 unit of platelets and 2 units of packed red blood cells transfusions were given within the posttransplant period. Early transplant related mortality was 3%. This paper describes the response and tolerance of each particular step of therapy. The follow-up has been too short to evaluate event-free and overall survivals.

RESUMO

The authors pay attention to one of the indicators of the health status of the economically active population--to the consumption of drugs. The analysis was based on outpatient records on health and disease in a selected group of 2,080 patients (25.9% of the basic group) in relation to sex, age and work capacity. The drug consumption of persons unable to work was cca 40% of the total drug consumption, whereby a higher consumption was recorded in women. With advancing age the drug consumption in diseases not associated with work incapacity rises markedly. Age practically does not influence the drug consumption on account of diseases causing work incapacity.

RESUMO

The decisive point is the suitable time of antibiotic administration, their combination and possibility to extend the surgical repertoire by prevention in particular of general complications. Wound healing is more rapid, and intended adjuvant treatment can, due to the reduce period of wound healing, be applied much sooner. It is more effective and the attainment of target structures by the administered drugs is not blocked by prolonged processes which are sometimes associated with fibrosis, scars and regressive tissue changes.

RESUMO

The effects of i.v. administration of the calcium channel blockers--verapamil (0.045 and 0.45 mg.kg-1) and Mepamil (2-methylphenyl-derivative of verapamil; 0.0445 and 0.445 mg.kg-1) on the cardiovascular system of rabbits in vivo under the paced and non-paced heart conditions were investigated. Verapamil induced--in the dose-dependent manner--a decrease in blood pressure (max. 65.2%), a significant decrease in dP/dtmax. (max. 46.0%), a bradycardia (max. 79.4%), a decrease in minute blood flow (max. 63.9 %) and stroke blood flow (max. 71.5%). The administration of Mepamil did not induce important changes in heart rate; changes in other parameters were--again in the dose-dependent manner--of a similar qualitative character as after verapamil administration, but they were quantitatively less expressed (especially marked in the effect on dP/dtmax, where the maximum decrease was only to 71.5%). The results show a less pronounced cardiodepressive activity of Mepamil compared to verapamil in rabbits.

RESUMO

The author pays attention to the drug consumption of the population, particularly of the economically active population. Special attention was devoted to an analysis of drug consumption in the above population group during periods of work incapacity. The investigation was based on used medical prescriptions. It was revealed that the economically active population participates in drug consumption by cca 50%, whereby the drug consumption of the population during work incapacity is cca 30% of consumption by the economically active population and accounts for cca 15% of the drug consumption of the entire population.
