[Essential cryofibrinogenemia with generalized livedo racemosa].

A 45-year-old male patient presented with cold-induced generalized livedo reticularis, repeated acral ulcerations and purpura, Raynaud's phenomenon, and peripheral polyneuropathy. The patient also experienced malaise, vertigo, and transient amaurosis whenever he was exposed to low temperatures. Skin biopsies of the livedo reticularis revealed marked dilatation of the small dermal blood vessels and circumscribed leukocytoclastic vasculitis. Essential cryofibrinogenaemia was diagnosed on the basis of detection of this cryoprotein in the chilled blood plasma with increased viscosity. Pulsed therapy with dexamethasone and cyclophosphamide resulted in marked relief of the symptoms, and cryofibrinogen was no longer detectable in the patient's plasma.

Adult Toxocara canis encephalitis.

A 48-year-old patient with Toxocara canis infection developed severe ataxia, rigor and neuropsychological disturbances. An aetiology was proven by an indirect immunofluorescence test. CT and MRI revealed both diffuse and circumscribed white matter lesions. Angiography showed multiple occlusion of branches of the middle cerebral artery. Anthelminthic treatment was beneficial in the initial stage of the disease, but had no effect on progression of CNS symptoms. Immunosuppressive therapy with prednisolone and azathioprine yielded partial recovery and stabilisation of the patient.

[Acute plasma cell leukemia. Clinical course during high-dose melphalan therapy].

A 29-year-old woman, with a slightly elevated temperature for 3 weeks, increasing dyspnoea at rest, markedly reduced general condition and in heart failure, was found to have a leucocytosis of 100,000/microliters, anaemia (haemoglobin 6.3 g/dl) and thrombocytopenia (41,000/microliters). There were 62% plasma cells in the blood smear. Immunoelectrophoresis of serum and urine revealed kappa-light chains and immunocytology demonstrated IgG-kappa. There was no radiological evidence of osteolysis, while ultrasound examination showed multiple abdominal lymphomas and marked hepatosplenomegaly. Bone marrow smear showed a 90% infiltration of plasma cells. High-dosage melphalan treatment (single intravenous injection of 140 mg/m2) resulted in complete remission after myelodepression over several weeks. Two extramedullary recurrences 5 and 12 months after the diagnosis had been made were successfully treated with high-dosage melphalan, but it was associated with severe and long-lasting myelodepression. Septicaemia with renal and hepatic failure developed and the patient died 6 weeks after the third course of high-dosage melphalan, 14 months after the diagnosis.

Prevalence of Helicobacter pylori in patients with chronic renal failure.

The prevalence of Helicobacter pylori (H. pylori) was investigated in 164 consecutive patients with different degrees of renal function; group I (normal renal function) n = 84, group II (chronic renal failure, CLCR > or = 5 < 90 ml/min) n = 45, group III (haemodialysis therapy) n = 35, to test the hypothesis that the resulting different concentrations of urea in the gastric juice would have an influence on the colonization of the gastric mucosa by these urea-splitting bacteria. As every individual method for the detection of H. pylori shows disadvantages, the results of the detection methods used (urease test, Warthin-Starry stain, bacterial cultivation, direct examination of the processed sample by phase-contrast microscopy) were combined in a cumulative evaluation. These calculated cumulative indices for the antrum and corpus showed no statistically significant differences between the studied groups. The prevalence of H. pylori ranged from 34 to 54%. The histopathological findings were similar in all groups. In spite of the fact that patients with renal dysfunction had significantly higher levels of serum gastrin (P < 0.05), there was no influence on the gastric juice pH value. The relationship between the cumulative index and ammonia concentration in gastric juice was found to be linear (P < 0.05). The higher urea levels in the blood and gastric juice of patients with renal failure do not seem to be a risk factor for infection with H. pylori.

[Immunotherapy of chronic Guillain-Barré syndrome with high dose IgG and cyclosporin A. Case report, review of the literature and perspectives].

We report about the three-year treatment of a patient with chronic relapsing Guillain-Barré syndrome (GBS), who, simultaneously, suffered from benign gammopathy. A casual relationship between the two diseases could not be proven, since specific antimyeline antibodies could not be found. Five severe bouts of the disease occurred during the observation period, only the first two relapses, however, showed improvement with cortisone treatment, while the latter did not so. High dosages of 7S-immunoglobuline, by contrast, led to a rapid improvement during each of the subsequent relapses. The additional therapy with ciclosporine A kept the patient free from neurological deficits for more than six months now. The mechanisms of various immunological therapeutic approaches are discussed, particularly as an alternative to plasmapheresis. Our observation, as well as theoretical considerations, suggest the aforementioned immunological treatment being promising in chronic GBS.

[Retinopathy as the first symptom of hairy cell leukemia].

Hairy cell leukemia is a seldom non-Hodgkin-lymphoma of the B-cells. The case of a 39 year old male with loss of vision as first sign of hairy cell leukemia is presented. The decrease of vision was caused by intraretinal bleeding into the macula. By means of ophthalmoscopy and angiography we found intraretinal bleedings, soft exudates, microaneurysms and capillary occlusions. The examination of blood cells showed leucocytosis (48.900/microliter), anemia (hemoglobin 8.7 g/l), thrombocytopenia (67.000/microliter) and hairy cells in peripheral blood and in bone marrow. Under treatment with alpha-Interferon visual acuity became normal and the fundus lesions decreased. This case points out that a retinopathy with bleedings and soft exudates can be caused by leukemia which should therefore be excluded by differential blood count.

[Detection of bone marrow involvement in breast cancer and malignant lymphoma using immunoscintigraphy of the hematopoietic bone marrow].

Radioimmunoimaging of bone marrow was performed for non-invasive detection of skeletal involvement in 15 patients with carcinoma of the breast and 17 patients with malignant lymphomas. Bone marrow scans were performed by means of a monoclonal 99mTc-labelled antibody, directed against NCA-95 and CEA. The presence and extent of skeletal involvement were controlled by skeletal scintigraphy, plain radiographs and CT; bone marrow biopsies were obtained in 19 patients as well. 20 subjects without suspected malignant disease served as controls. Haematopoietic bone marrow was imaged homogeneously and with high contrast in all controls. 15/15 patients with carcinoma of the breast and 10/17 patients with malignant lymphomas had multifocal bone marrow defects due to skeletal metastases. Bone marrow scans revealed significantly more lesions than skeletal scintigraphy both in carcinoma of the breast (p = 0.027) and malignant lymphomas (p = 0.015). Thus, radioimmunoscintigraphy of bone marrow may provide a new, sensitive approach for non-invasive detection of metastatic spread to the skeletal system.

Posttransfusion purpura associated with an anti-Bak.

We describe a 46-year-old white woman with typical clinical features of posttransfusion purpura (PTP) whose serum held a platelet-specific alloantibody reactive with an antigen antithetical to Baka, i.e. anti-Bakb. The specificity of the antibody was confirmed by family analysis, a population study (expected versus observed gene frequency: 0.3651 versus 0.3984; n = 105) and localization of the antigen on glycoprotein IIb in radioimmunoprecipitation. Typing of family members and blood donors for platelet antigens disclosed that the patient had been preimmunized by two blood transfusions in 1981, while fetomaternal incompatibility for Bakb was ruled out (her three children and their father were Bakb negative). Treatment of PTP with corticosteroids and platelet transfusions was ineffective, but infusion of high-dose intravenous IgG resulted in a rapid increase in the platelet count.

[Transfusion malaria in promyelocytic leukemia].

Five weeks after re-induction treatment and nine days after discharge from hospital, remittent fever occurred in a 34-year-old woman with promyelocytic leukaemia in full remission. She also had haemolytic anaemia and thrombocytopenia, as well as a reduced creatinine clearance. Findings on physical examination were unremarkable, but Falciparum malaria was found in the blood smear. Infusion of erythrocyte or platelet concentrates, administered in treating the leukaemia, was the probable source of the infection. Ten days after starting the administration of chloroquine and sulfadoxine-pyrimethamine she was discharged from hospital, cured of the malaria.
