    Notes: Summary Conditioning therapy with aggressive chemotherapy and irradiation induces a state of transient combined immunodeficiency in bonemarrow transplant recipients. This promotes the occurrence of severe cytomegalovirus (CMV) infections, the most frequent lethal complication after bone-marrow transplantation (BMT) at present. Forty-four BMT recipients received CMV-IgG-hyperimmunoglobulin for CMV prophylaxis intravenously. The efficacy of this prophylaxis and possible risk factors for the occurrence of CMV-induced interstitial pneumonia (IP) were analyzed. Risk factors for the promotion of a CMV-IP were: additional immunosuppressive therapy after BMT, CMV-positive serostatus of the recipient, CMV-seropositive granulocyte transfusion, CMV infection immediately prior to BMT, and HLA-haploidentical BMT. In this study the incidence of graftversus-host disease was low and was not associated with the incidence of CMV infections. The use of T-cell-depleted grafts did not result in increased CMV infections or IP and may possibly have improved the immunological reconstitution.

    Notes: Summary Parvovirus B19 lytically infects erythroid progenitor cells and thereby causes cessation of erythropoiesis in infected individuals. Anemia develops only if red cell turnover is increased, as in patients with chronic hemolysis (transient aplastic crisis). In addition to transient marrow failure, B19 can cause chronic anemia and, rarely, pancytopenia in immunodeficient patients who are not able to mount an adequate immune response to clear the virus. Bone marrow transplantation, although causing significant immunosuppression, is rarely complicated by symptomatic B19 infection. This is probably due to effective passive immunotherapy by immunoglobulin infusions immediately after transplantation and early reconstitution of antibody responses after uncomplicated transplantation.

    Notes: Summary A patient with a myelodysplastic syndrome (MDS) and reticulocytosis of 〉50% in the absence of a correspondingly increased erythrocyte turnover is reported. Evaluation of the kinetics of erythrocyte turnover revealed a decreased erythrocyte life span of 44 days. From these data a prolongation of the reticulocyte maturation time to 〉20 days can be concluded. The patient's erythrocytes lacked the increase of mean corpuscular volume and a significant increase of erythrocyte enzymes that would be expected in marked reticulocytosis. This finding suggests that the reticulocytes represented not newly formed red blood cells, but “pseudoreticulocytes”, i.e., mature erythrocytes that retained their substantia reticulofilamentosa.

    Topics: Medicine
    Notes: Summary Thrombotic thrombocytopenic purpura (TTP) is a hematologic disorder which is clinically characterized by thrombocytopenia, microangiopathic hemolytic anemia, fever, neurologic symptoms, and cardiac and renal involvement. The pathogenic mechanisms of this disease are poorly understood. It is well known that TTP is associated with pregnancy and that prognosis for the mother and child is poor. We present the first case of a severe TTP diagnosed in the first trimester of pregnancy (13th week of gestation) with maternal survival and birth of a healthy child which required continuous and intensive treatment with plasmatherapy until delivery. During a period of 24 weeks several attempts to discontinue plasma therapy failed because of continuous active disease, and it became evident that plasma infusions were not as effective as plasma exchanges. The fact that the patient entered into remission soon after delivery of a healthy child by cesarean section in the 37th gestational week shows that in this case pregnancy activated an unknown factor which does not cross the placenta and which can be removed by plasmapheresis.

    Notes: Abstract  The methodology of decision analysis was originally developed to improve clinical decisions of physicians for individual patients. However, it is also well suited to support consensus procedures. We have used this methodology to analyse the question whether allogeneic bone marrow transplantation (BMT) or consolidation chemotherapy (CCT) should be used as first line postremission treatment in patients with acute myeloid leukemia. Main risk factors relevant for the outcome after BMT and CCT are therapy-related mortality and leukemic relapse, respectively. If the possibility of salvage BMT for patients relapsing after CCT is included, the outcomes of the two strategies come rather close. However, they are clearly different in subtypes of leukemia with high or low risk of relapse, and in patients at high risk for BMT-related mortality. Sensitivity analysis considering the variation of more than one risk factor provides valuable information for decision making for both individual patients and particular subgroups of patients with acute myeloid leukemia.

    Notes: Summary The incidence of invasive fungal infections after bone marrow transplantation (BMT) was analyzed in 303 consecutive marrow graft recipients (allogeneicn=271, autologousn=27, syngeneicn=5). All patients received inhalations with amphotericin B (10 mg twice daily) during neutropenia. The overall incidence of invasive fungal infections within the first 120 days after transplant was 3.6% (11/303; aspergillosis: 6; yeast infection: 5). Four of the 11 cases occurred early, and seven cases were observed after neutrophil recovery and discontinuation of amphotericin B inhalation treatment. Late infection was significantly associated with the development of acute graft-versus-host disease. Four of the 11 infections (early 2/4; late: 2/7) were observed in patients with a history of previous fungal infection. Other patient and treatment characteristics were not helpful in defining potential risk factors. In particular, the incidence of invasive fungal infections did not differ between patients with more or less strict reverse isolation measures. Occasional side effects such as initial mild cough and bad taste were rare, usually disappeared during continued administration, and were in no case the reason for discontinuation of treatment. These data suggest that aerosolized amphotericin B may be a useful, convenient, and efficient prophylactic antifungal regimen in BMT.

    Notes: Abstract  Acute abdomial pain is a frequent diagnostic and therapeutic challenge in hematologic patients. We report on the very rare case of organ endometriosis with acute abdominal symptoms in a 43-year-old female patient with AML-M5, starting 4 days after induction chemotherapy with idarubicin, ara-C, and etoposide. The patient presented with an acute abdomen with clinical findings of acute cholecystitis, subileus, and local pain in the right upper abdomen accompanied by severe diarrhea. Probably due to impaired intestinal resorption, menstrual bleeding occurred despite regular administration of lynestrenol. Ultrasound examination of the abdomen disclosed a tumor with poor echoes in the pouch of Douglas, a subcapsular splenic hemorrhage, and a thickened gallbladder wall with surrounding edema. A cystic adnex tumor was confirmed by endovaginal ultrasound. Based on history and the findings on ultrasound, an endometriosis was diagnosed, and the LHRH agonist (nafarelin) was administered nasally in combination with lynestrenol. Following this medication the abdominal pain ceased, supporting the diagnosis of endometriosis. Nasal administration of an LHRH agonist in the following cycles of chemotherapy was effective in preventing further abdominal discomfort and vaginal bleeding. LHRH agonists should be given to patients with known endometriosis before starting myeloablative chemotherapy to prevent painful hemorrhage from endometriosis.

    Notes: Abstract  A female patient with eosinophilia and cardiac symptoms was found to have a unique chromosomal aberration [t(4;7)(q11;p13)] of bone-marrow precursors. The disorder was classified as a chronic myeloproliferative syndrome with eosinophilia. Due to a significant increase in the white blood cell and eosinophil count during initial treatment with prednisone and hydroxyurea, Interferon alpha-2a was administered at a dose of 3–5×106 I.U. s.c., five times per week, and induced a long-term complete haematological and cytogenetic response. The clinical features of this case are presented and discussed in the context of the current literature.

    Notes: Abstract Recent reports suggest the possible beneficial effects of haemopoietic stem cell transplantation (HSCT) in autoimmune diseases such as multiple sclerosis (MS). The definition of the risk/benefit ratio for such a treatment is perceived as a major issue for the neurological community worldwide. The First Consensus Conference on Bone Marrow Transplantation in Patients with Multiple Sclerosis was held in Milan, Italy on 21 February 1998. Participants from 16 European, North American, and South American countries discussed the guidelines form performing HSCT in MS. This conference was organized in order to : (a) define criteria for patient selection; (b) define transplantation procedures to maximize efficacy of the treatment and minimize its toxicity; (c) standardize patient outcome evaluation; and (d) establish an international working group to evaluate the efficacy and safety of HSCT in MS and to study the immunological changes related to HSCT in MS patients. During the meeting in Milan agreement was reached on: (a) the preparation and distribution of a consensus report on HSCT in MS and (b) the design of an open trial for an initial assessment of the safety and efficacy of HSCT in MS. The consensus reached during the meeting and the design of the clinical trial are summarized in this contribution.
