OBJECTIVE: To quantify the progression of diabetic polyradiculoneuropathy-a condition in which immune factors have been implicated-after immunotherapy. METHODS: The study evaluated 15 consecutive patients with this condition. All patients were older than 40. Four had type I diabetes and six were women. The duration of pre-existing diabetes varied from 2 to 20 years. The clinical presentation was dominated by painful progressive motor weakness, with or without exacerbation of sensory symptoms. The weakness involved all limbs, but was often asymmetric. RESULTS: Electrophysiological testing showed a predominantly axonal polyneuropathy, with more recent denervating polyradiculopathy. Analysis of CSF showed increased protein in 14 and oligoclonal bands in five. Quantitative autonomic tests showed abnormalities in all patients. Sural nerve biopsy was performed in 14 patients; all showed fibre loss and segmental demyelination, four had occasional onion bulbs, and 10 showed various inflammatory infiltrates. After immunomodulating therapy, there was no further deterioration and clinical improvement occurred in all patients. Sweat responses, cardiovascular reflexes, and sural nerve fibre density correlated best with functional outcome. There was no significant difference between plasmapheresis and intravenous gammaglobulin. CONCLUSION: Immunotherapy may improve this condition, but only certain variables correlate with rapid therapeutic response. 相似文献

We have reviewed our experience with conversion to tacrolimus after 435 liver transplantations. Tacrolimus was administered as a rescue agent in 33 patients until October 1993. Indications for rescue therapy were: cholestatic forms of severe, steroid-resistant cellular rejection (n=8), OKT3-resistant cellular rejections (n=6), cellular rejections in patients suffering from cyclosporin malabsorption (n=4), late onset cellular rejections (n=4), early chronic rejections (n=3), and chronic vascular or ductopenic rejections (n=8). Response was evident in 29 of the 33 patients (88%), whereas 4 patients (12%) were nonresponsive. Patient and graft survival were 76% and 70%, respecitively. Graft loss with or without patient death occurred in three of eight patients suffering from severe, steroid-resistant cellular rejection, in two of six patients with OKT3-resistant cellular rejections, and in five of eight patients undergoing chronic rejection. In severe steroid-resistant cellular rejection, successful tacrolimus rescue therapy corresponded to a significantly lower total serum bilirubin than unsuccessful therapy (12.0±5.6 mg% vs 29.7±5.9 mg%, P(0.05). We conclude that tacrolimus rescue therapy is a safe and efficient alternative for high-risk cases that do not respond to conservative treatment. In severe, steroid-resistant cellular rejection and in chronic ductopenic rejection, conversion to tacrolimus is beneficial only in a limited number of cases. A predictive parameter, which total serum bilirubin may prove to be in severe, steroid-resistant cellular rejection, is needed to select those cases that might benefit more from retransplantation than from conversion to tacrolimus. 相似文献

Peripheral blood eosinophilia is a well-recognized paraneoplasia in many kinds of hematological and nonhematological malignancies. We report the case of a patient with a malignant fibrous histiocytoma. With increasing tumor burden, the patient developed a marked peripheral blood eosinophilia. Using an in vitro assay for growth of eosinophilic colonies, both the serum and the tumor of the patient proved to contain an eosinophilopoietic activity. 相似文献

Clinical outcome and adverse effects associated with concurrent alprazolam and imipramine administration were studied in 29 patients with major depressive disorder who completed a 6-week trial in which they served as their own controls. Alprazolam was added on Day 8 in gradually escalating, then gradually tapering dosages while imipramine dosages remained unchanged. Significant decreases were observed in scores on the Hamilton Rating Scales for Depression and Anxiety at all later evaluation days with Day 8 as baseline. The mean total Symptom and Side Effects score decreased significantly from Day 8 to Day 22 when alprazolam doses were 1 mg q.i.d. For most side effects, total number of reports remained constant or decreased from Day 1 to later evaluation days. Standing diastolic blood pressures were significantly lower on Day 22 than on Day 1. No significant relationship was found between any rating scale score and plasma concentration data. 相似文献

Reinfection of the graft with hepatitis B virus (HBV) and hepatitis delta virus (HDV) is a potential complication in patients undergoing orthotopic liver transplantation (OLT). Therefore, we added recombinant interferon-alpha (rIFNa) to the standard immunosuppressive regimen in 11 patients who received transplants following liver failure attributed to cirrhosis B (n = 10, with HDV co-infection in four cases) or fulminant hepatitis B (n = 1). Patients were treated with rIFNa for periods ranging from 2 to 3 months between the first and the 13th month after OLT. All patients received immunosuppressive treatment with low-dose corticosteroids, azathioprine and cyclosporine. Anti-HBs hyperimmune globulin was also administered. None of the patients showed evidence of severe allograft rejection. Seven patients suffered HBV reinfection of the graft with histological signs of acute hepatitis in five cases and transition to chronic hepatitis in one patient. Treatment with rIFNa did not prevent or reduce HBV replication. Reinfection of the graft with HDV was demonstrated by PCR in four patients co-infected with HDV. During treatment with rIFNa liver biopsy specimens from three reinfected patients were transiently negative for HDV antigen but not for HDV RNA, and the sera from two patients were transiently negative for HDV RNA. The data indicate that rIFNa can reduce HDV replication in reinfected liver allografts. 相似文献

Immunocytochemical analysis of lymph node aspirates in patients with human immunodeficiency virus infection. 下载免费PDF全文
Thirty four patients positive for human immunodeficiency virus (HIV) who had lymphadenopathy were investigated using fine needle aspiration. Cytological analysis included immunocytochemical investigation with the alkaline phosphatase-antialkaline phosphatase (APAAP) method. All patients had confirmation of cytological diagnosis by lymph node biopsy. Fifteen aspirates with follicular hyperplasia were evaluated. Eleven patients showed B cell predominance. The B cell population did not show light chain restriction. Ten patients with B cell non-Hodgkin's lymphoma (five with Burkitt's lymphoma and five with B cell immunoblastic lymphoma) were investigated. Nine out of 10 cases were monoclonal with respect to their light chain determinants; only one case with Burkitt's lymphoma with partial lymph node metastasis did not show light chain restriction. The cytological diagnosis included two mycobacterial infections and four cystic lesions. Histological investigation was necessary to diagnose the extent of lymph node disease caused by Kaposi's sarcoma. These findings indicate that the immunocytological investigation of lymph node aspirates is useful for evaluating lymphadenopathy in HIV positive patients. 相似文献
