[Immunological abnormalities in myelodysplastic syndromes. Prospective study (series of 40 patients)].

UNLABELLED: The association of myelodysplastic syndromes (MDS) with auto-immune diseases and humoral disorders have already been reported. In this prospective study we tried to estimate type and the frequency of immunological associated diseases among patients affected by MDS. PATIENTS-METHODS: In this prospective study, auto-immune disease and humoral immunity disorders were systematically searched during MDS and conversely MDS searched during cytopenia. All MDS secondary to chemotherapy and the children's MDS were excluded. The MDS diagnosis was established according to FAB criteria and patients were classified in two groups A or B according to presence (group A) or not (group B) of dysimmune manifestations. RESULTS: Forty patients(19 males and 21 females, mean age of 56,6 years) with MDS have been enrolled during this period (group A: 20 patients). Associated diseases are following: systemic lupus erythematosus (three), lupus-like syndrome(one), sarcoidisis(one), Sjogrën syndrome(one), polyarthritis (two), chronic liver diseases (three), autoimmune thyroid diseases (two), pyoderma gangrenosum (one), Crohn's disease(one), haemolytic anaemia (one), and pericardial effusion(one). CONCLUSION: A wide spectrum of auto-immune manifestations is frequently reported in myelodysplastic syndromes. Further studies are necessary for discuss the current physiopathological hypothesis with their therapeutic relevance.

Severe hypofibrinogenemia associated with bilateral ischemic necrosis of toes and fingers.

Severe hypofibrinogenemia was found in an Algerian woman who, since the age of 37 years, suffered three different episodes of ischemic necrosis of the toes and fingers leading to amputation of the toes and surgical removal of necrotic tissue (necretomy). No anti-fibrinogen antibody was present. The deficiency appeared to be due to severe congenital hypofibrinogenemia since the fibrinogen level remained at the same low level over a long period, without any abnormality of other coagulation proteins. The thrombotic events may be explained by the increased thrombin generation observed in the patient's plasma, due to the lack of thrombin adsorption onto a fibrin net.

[Hodgkin disease, clinical stages IA-IIB: evaluation of the value of cisplatin. Preliminary results].

Cisplatinum is highly effective in numerous solid tumors and was evaluated in Hodgkin's disease clinical stages (CS) I/II. Sixty-five patients (43 male, 22 female; median age 25, with 12 patients under 16: CS IA-IIA 41, IB 5, IIB 19) were randomly assigned to one of the following arms (PAF87 protocol): 3 ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine with methylprednisolone) cycles (ABVD arm) or 3 ABVD plus cisplatinum cycles (ABVD-Plt arm) followed by radiotherapy (RT); extended field (40 Gy) RT with a short paraaortic field including the spleen (30 Gy) was then administered in the ABVD arm; extended field (30 Gy) without lombosplenic port prophylaxis. RT was administered in ABVD-Plt arm when patients were in complete remission (CR) after chemotherapy (CT). Median follow-up was 35 months (6-62 months). During CT, 1 patient (ABVD-Plt) died from viral meningo-encephalitis; five patients (1 ABVD, 4 ABVD-Plt) stopped treatment because of emesis, of whom three receiving only 1.5-2.5 (ABVD-Plt) cycles, are still in CR after 13-60 months. Fifty-five patients (27 ABVD-Plt) were in CR after CT. Among the 27 ABVD-Plt patients, all in CR after RT, two died (one from myocardial infarction and one from immunoblastic lymphoma); one patient from the ABVD arm died from gastro-intestinal hemorrhage in 1st CR. No ABVD-Plt patient relapsed; 1 ABVD patient relapsed in non-irradiated area. At five years, actuarial survival/relapse-free survival was 96.1/90% and 88.2/100% for ABVD and ABVD-Plt patients, respectively.

[1st cases of alpha-thalassemia in Algeria: 12 cases of hemoglobinosis H].

These first cases of hemoglobinosis H show that alpha-thalassemia is not a simple curiosity in this part of the Western Mediterranean. They are not localised to a single part of Algeria as the areas from which the patients came were more than 150 km apart. They suggest that the enquiry should be continued by other means to determine the prevalence and pathological incidence.

[Comparison between acute myeloblastic leukemia in children and adults].

The clinical, hematological and therapeutic aspects of 36 cases of acute myeloblastic leukemia in children and 98 cases in adults observed in Algeria are discussed. In Algeria, acute myeloblastic leukemia is more frequent in children than in other populations. In our series there was a very unusual female predominance. Clinically, we observed in children only, 8 cases of chloroma of the orbit. From the hematological point of view, the only difference was a higher incidence of leukopenia and hyperleukocytosis after the age 30 years. The results of VAMP treatment (vincristin, amethopterin, 6-mercaptopurine, and prednisone) are better in children than in adults. But analysis of the results is more interesting if one places the patients in age groups of ten years. The percentage of complete remissions is maximum in the age group 0 to 10years and then falls regularly.
