    Notes: Summary Twenty-three patients with aplastic anemia (18/23 with severe aplastic anemia) were treated with an immunosuppressive regimen consisting of cyclosporin A (CsA) and methylprednisolone (MP) (n=7) or CsA, MP, and antithymocyte globulin (ATG;n=16). Nineteen patients are alive with a follow-up of 4 to 25 months; three patients died of infections and one of a gastrointestinal hemorrhage. Within 3 months, improvement of hematopoiesis was seen in 14 patients (61%). First signs of a response after 23 to 88 days were followed by complete remission in eight patients, partial remission in three patients, and minimal improvement in three patients. Two of the patients with only minimal improvement were treated with a second course of immunosuppression and reached a complete remission and partial remission. Interestingly, remission proved to be dependent on the continued administration of CsA in four of five patients with partial or complete remission who could be evaluated up to now. Thus, CsA must have been effective in the induction and/or maintenance of remission in three patients. This observation is a very strong argument for the role of T cells in the pathogenesis of at least some cases of aplastic anemia and warrants further evaluation of the role of CsA in the treatment of aplastic anemia.

    Notes: Summary The clinical, immunological, and serological status of 28 patients with hemophilia A and of 13 patients with hemophilia B was investigated. Thirty-four patients were treated regularly by clotting factor concentrates and 7 patients had been substituted only 1 to 4 times. Almost all patients with severe hemophilia suffered from hepatopathy. No patient had clinical evidence of the acquired immunodeficiency syndrom (AIDS). Asymptomatic hemophiliacs showed a decreased number of T-helper (OKT 4) cells and an increased number of T-suppressor (OKT 8) cells, which resulted in an inversed OKT 4/OKT 8 cell ratio. Natural killer cell activity of all patients was decreased compared to controls. After culture there was no significant difference of NK cell activity between hemophiliacs and controls. This phenomen was interpreted as a possible maturation defect of NK-cells in vivo. No relationship between immunological alterations and hepatopathy, hepatitis markers, CMV antibodies, amount and source of required factor concentrates, and the kind of hemophilia was observed. IgG immunoglobulins were higher and the OKT 4/OKT 8 ratio lower in the eight patients with lymphadenopathy than in patients without lymphadenopathy. The prevalence of antibodies to human T-lymphotropic virus (HTLV III) was measured in 35 hemophiliacs and in 25 polytransfused patients, most of whom were suffering from acute leukemia. In 8 of 35 hemophiliacs antibodies to HTLV III virus were detected by an enzyme linked immunosorbent assay (ELISA) and confirmatory tests. All seropositive patients were treated by blood products from the United States. Eight hemophiliacs treated by factor concentrates from German donors only were seronegative. In comparison 2 of 25 examined non-hemophilia patients receiving multiple blood products from local donors were seropositive for HTLV III. The results show that hemophilia patients treated by imported clotting factor concentrates have a high risk of HTLV III positivity. Hemophiliacs substituted by blood products obtained by local donor pools have only a small risk of infection. Because non-hemophiliac polytransfused patients had HTLV III antibodies, there must be asymptomatic virus carriers in the local donor pool. The HTLV III antibody screening of all donors and the heat treating of factor concentrates will give better therapeutic safety.

    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 The impact of aggressive chemotherapy on reproductive and endocrine gonadal function was prospectively studied in 44 patients with germ cell tumors. Diagnostic procedures to determine gonadal toxicity consisted of hormone determinations, semen analyses, interviews with a standardized questionnaire, and gonadal histology. After chemotherapy all patients showed elevated serum levels of follicle-stimulating hormone (FSH) and azoospermia due to germ cell and stem cell loss. Recovery of spermatogenesis, as indicated by normalization of serum FSH levels and sperm density, occurred in 77% of the patients 25–60 months after cessation of chemotherapy. In all patients serum testosterone and luteinizing hormone (LH) values remained within normal limits after therapy indicating resistance of Leydig cells to cytotoxic drugs. Three patients fathered four healthy children after completion of chemotherapy. These data suggest significant reproductive dysfunction in all men treated for germ cell tumors. However, most patients showed late and complete recovery of spermatogenesis. In contrast, endocrine gonadal function was unaffected after chemotherapy in all patients. FSH and LH are feasible markers to assess drug-induced gonadal toxicity.

    Notes: Permanent immunoglobulin substitution therapy was performed in a 44-year-old patient with common variable immunodeficiency, recurrent respiratory tract infections, total absence of serum IgA and a high titre of class-specific anti-IgA antibodies. An IgA-depleted i.v. immunoglobulin (IG) preparation was used. Infusions were well tolerated by the patient although minor anaphylactoid symptoms regularly occurred. Anti-IgA antibody titres rose during the first 4 months of treatment and gradually fell during the following 8 months. Regular IG substitution therapy led to a substantial improvement in the patient's health and quality of life.

    Notes: Summary Testicular and ovarian functions were assessed in 33 patients with Hodgkin's disease 1 to 17 years after cessation of COPP chemotherapy with cyclophosphamide, vincristine, procarbazine, prednisone. Diagnostic procedures consisted of hormone measurements, interviews, and semen analyses. In women serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), 17β-estradiol, progesterone, prolactin, and in men FSH, LH, 17β-estradiol, testosterone, and prolactin were determined. Semen analyses were performed in all men. Information concerning pregnancies, pregnancy outcome, future fertility wishes, sexual functions, menstrual pattern, and incidence of premature menopausal symptoms was ascertained by interview and questionnaire. Nineteen of 19 (100%) men showed elevated serum FSH levels between 715 and 1910 (median 1095) ng/ml and azoospermia, 1 to 11 years afters therapy. Serum levels of testosterone were within normal limits in 18/19 (95%) of the men, and LH values were normal in all men. Permanent ovarian failure occurred in 8/14 (57%) women, causing infertility and premature menopausal symptoms. The incidence of ovarian failure in women over 24 years was 86% (6/7) versus 28% (2/7) in those under 24 years at the time of treatment. In women receiving estrogen replacement, incidence and severity of these symptoms were significantly reduced. Of 14 women 3(21%) became pregnant and delivered 5 healthy children after treatment. Our results suggest irreversible sterility and normal Leydig cell function after COPP chemotherapy in all men. Druginduced ovarian failure was age-related and caused premature menopausal symptoms, detracting from the quality of the patient's life. To reduce premature menopausal symptoms and to prevent adverse cardiovascular and metabolic late sequelae, hormonal replacement is indicated. Pregnancies ending in normal live births can be achieved after COPP chemotherapy in young women. In both men and women, serum FSH and LH levels proved to be feasible markers to determine degree and duration of endocrine and reproductive gonadal injury after chemotherapy.

    Notes: Summary Of 501 patients with chronic myeloproliferative diseases (c-MPD) 18 developed thrombosis of major abdominal vessels including 6 with hepatic vein thrombosis (Budd-Chiari syndrome). The complication was seen in 14 of 140 (10%) patients with polycythemia vera (PV), 3 of 23 (13%) patients with essential thrombocythemia (ET), 1 of 106 (1%) patients with idiopathic myelofibrosis (IMF), and none of 232 patients with chronic myelogenous leukemia (CML). Leading symptoms and signs were abdominal pain, progressive splenomegaly, widening abdominal girth, ascites, venous collaterals, and nausea and vomiting. The diagnostic modalities with highest specificity were angiography and explorative laparotomy. A causal relationship between the thrombotic event and hematocrit, thrombocyte count, or hemostatic abnormalities at the time of diagnosis could not be established. Detailed laboratory tests of platelet function and coagulation and fibrinolytic parameters of 5 surviving patients did not show any specific defect. Despite medical and surgical intervention, 39% of the patients died within 2 months after diagnosis of the thrombosis. The majority of the survivors developed further complications like liver cirrhosis with portal hypertension and esophageal varices or the short bowel syndrome after extensive bowel resection for mesenterial infarction.

    Notes: Summary Common manifestations of Wilson's disease are disorders of the liver and brain. A rare complication of this inherited disease is acute intravascular haemolytic anaemia. We report the case of a 33-year old female patient who was admitted to the hospital with acute haemolysis as the initial symptom of Wilson's disease. The haemolysis preceded the definitive diagnosis by 20 months. It is concluded that in any case of unclear haemolytic anaemia, especially in adolescents or in young adults, Wilson's disease should be considered.
