Interferon (IFN) therapy is of proven efficacy in chronic hepatitis C, but it is not universally effective and is often limited by side effects. Cyclosporine A (CsA) is a potent immunosuppressant widely used in organ transplantation. We conducted a pilot study to determine whether CsA therapy could affect aminotransferase activity and hepatitis C virus RNA levels in patients with chronic hepatitis C. Cyclosporine A was administered to 10 patients (mean age of 59 years; male: female = 9:1) who did not respond to IFN therapy previously and who had elevated serum alanine aminotransferase (ALT) values for at least 6 months. All patients were positive for HCV-RNA by RT-PCR with genotype 1b. Their mean duration of hepatitis was 15 years. Oral CsA was given for 3 months in a dose that was increased at 1 month intervals from 1.5–2.0 to 2.0–3.0 and 3.0–4.0 mg/kg per day. All patients completed the treatment schedule, although two patients developed mild non-symptomatic hypertension. Serum ALT levels gradually decreased in all but one patient. The mean percentage decrease was 59.5% at the end of therapy (from 153 ± 82 to 62 ± 48 IU/L; P < 0.02). The ALT levels fell to the normal range in five patients, although once therapy was discontinued the enzyme levels tended to return to pretreatment levels. Serum aspartate aminotransferase and g-glutamyl transpeptidase levels similarly decreased. The serum HCV-RNA titre, determined by competitive RT-PCR, did not change in any patient throughout the study period. There were no appreciable alterations in other laboratory tests, such as serum creatinine levels and lymphocyte subsets, except for an increase in serum alkaline phosphatase levels. These findings suggest that CsA, even in a relatively low dose, reduces serum aminotransferase levels without serious side effects in patients with chronic-hepatitis C, although an antiviral effect was not noted. 相似文献

Microdialysis has been used to determine the concentration of salicylic acid in skin tissue and plasma periodically for 4 h to evaluate the effect of ointment bases on topical and transdermal delivery of salicylic acid. The ointment bases examined were solbase (water-soluble), poloid and white petrolatum (oleaginous), hydrophilic poloid (water in oil (w/o) type emulsion lacking water) and absorptive ointment (w/o-type emulsion containing water). The ointments (0.1 g) containing 25 μmol salicylic acid were applied for 2 h to the surface of rat skin (1 cm2) with (intact) or without the stratum corneum. For intact skin, the extent of topical delivery from different ointments, evaluated by the area under the concentration-time curve (AUC) of salicylic acid in the skin tissue (AUCskin), increased in the order solbase. white petrolatum, poloid, hydrophilic poloid. absorptive ointment. The ratio of AUCskin (topical delivery) to the AUC of salicylic acid in plasma (AUCplasma, transdermal delivery) varied remarkably among the different bases, the greatest ratio being observed for absorptive ointment. When the ointments were applied to skin surface without stratum corneum, AUCskin for solbase was much higher (about 45 times that for intact skin), whereas only a small (two-fold) increase was observed for poloid and hydrophilic poloid and the increase was negligible for white petrolatum and absorptive ointment. For skin without the stratum corneum, the ratio AUCskin/AUCplasma for the different ointments was comparable, although the magnitudes of AUCskin and AUCplasma still varied substantially. The variance of AUC values arises as a result of the different rates of release of salicylic acid from the bases. These results indicate that: the topical and transdermal delivery of salicylic acid in intact skin varies substantially among different ointment bases, and the greatest topical delivery is observed for absorptive ointment; use of absorptive ointment increases the retention of salicylic acid in the stratum corneum; and the stratum corneum functions strongly as a penetration barrier for solbase, moderately for poloid and hydrophilic poloid, and less for absorptive ointment and white petrolatum. 相似文献

We previously reported that the number of TNF-α-producing cells was increased in the liver of patients with type C chronic liver disease. To understand further the pathophysiology of this change, we examined serum levels of two soluble TNF receptors, TNF-αRI (p55) and -αRII (p75), and IL-10, all of which act as TNF-α buffer, and IL-15, a novel cytokine sharing many immunological activities with IL-2, using ELISA methods. We studied control individuals and patients with type C chronic liver disease, including asymptomatic hepatitis C virus (HCV) carriers with persistently normal serum ALT values, and those with chronic hepatitis (CH), liver cirrhosis (LC) and hepatocellular carcinoma (HCC). Both types of sTNF-αR closely correlated with disease progression. Patients with LC and HCC had significantly elevated levels for sTNF-αRII compared with the other patient groups and controls. Serum IL-10 levels were significantly greater in all chronic liver disease groups than in controls. With respect to IL-15, the values were high in CH, LC and HCC compared with those of controls. Notably, HCC patients showed highest values for both IL-10 and IL-15, with significant differences from the other patient groups. Serial determinations revealed that interferon (IFN) treatment for CH patients resulted in the suppression of circulating IL-10 and IL-15 levels along with decrease in serum aminotransferase values. Both cytokines remained at decreased levels after cessation of therapy in patients who went into clinical and virological remission. On the other hand, treatment did not affect serum levels of sTNF-αRs. These findings indicate that serum levels of these molecules correlated with disease progress in chronic HCV infection, and that IL-10 and IL-15 may reflect the degree of inflammation in the liver. It is also suggested that both cytokines may be related to the development of HCC. 相似文献

We report a case of chronic myelogenous leukemia (CML) associatedwith pronounced peripheral lymphadenopathy, with the cells havingthe Philadelphia (Phl) chromosome and T-cell features. A 23-year-oldman who was diagnosed as having CML and treated with busulfanwas admitted to our hospital because of increasing hepatosplenomegalyand pronounced lymphadenopathy. An axillary lymph node biopsydisclosed that the malignant cells formed rosettes with neuraminidase-treatedsheep red blood cells (En) (95.0%) and were positive for Leu1 (91.8%). Of the cytochemical reactions, peroxidase was negativeand periodic acid-Shiff, acid -naphthyl acetate esterase andß-glucuronidase were all positive. The karyotype ofthe bone marrow cells was 46 XY Phl positive (22q), andthat of the lymph node cells was 51 XY Phl positive +8, +9,+18, +19, +21, 22q. He was treated with various anti-leukemicagents and irradiation. Despite such treatments, he died ofpneumonia. This is a report of a CML patients with blast crisisand tumor formation characterized by T-cell features. 相似文献

Frontal sinus infection after incorrect treatment of an opened frontal sinus may require extended approaches. This article aims to introduce modified cranialization technique and secondary cranioplasty for frontal sinus infection involving the frontal sinus outflow tract after craniotomy. Eight patients with delayed onset frontal sinus infection involving frontal outflow tract after craniotomy were treated from 2008 to 2012. Debridement and cranialization involving the elimination of the frontal outflow tract was performed. Unilateral sinus cranialization combined with reduction of the non-affected contralateral sinus was carried out for the patients with unilateral sinusitis. A pericranial-frontalis muscle flap was used to separate the intracranial and extracranial spaces. Secondary cranioplasty with hydroxyapatite was performed approximately 3 months after the cranialization. The patients’ original conditions included brain tumors (n = 3), frontal sinus fractures (n = 2), and subarachnoid hemorrhage (n = 3). The mean interval between the initial treatment and the onset of sinus infection was 23 years. The frontal sinus infection was bilateral in six cases and unilateral in two cases. Frontal sinus outflow tract was involved in sinus infection in every case. None of the patients suffered recurrent rhinogenic infections within the follow-up period (mean = 35 months) after the secondary cranioplasty. Aesthetic results were satisfactory in every case. Modified cranialization involving elimination of the frontal outflow tract is an alternative method for the patients with pathology in the frontal outflow tract after frontal craniotomy. Secondary cranioplasty provides an esthetically pleasing appearance in such cases. 相似文献

OBJECTIVE: The aim of this study was to test the effect of gut manipulation by either novel synbiotics or by metronidazole on either endotoxemia or the severity of liver damage in the course of acute pancreatitis from alcohol ingestion. METHODS: Sprague–Dawley rats were fed for 1 week through an intragastric tube a liquid diet with either: (i) 1 mL t.i.d. of a mixture of synbiotics (Lactobacillus acidophilus, Lactobacillus helveticus and Bifidobacterium in an enriched medium); (ii) 20 mg/kg t.i.d. metronidazole; or (iii) standard diet. Then, acute pancreatitis was induced by caerulein and when the disease was full‐blown, rats were fed an alcohol‐rich diet. Synbiotic and metronidazole treatment was given for a further 2 weeks. Transaminase and endotoxemia levels were measured before treatment, after 6 h, after 24 h and 2 weeks later, at the time the rats were killed. Liver samples were obtained for histological analysis. RESULTS: Synbiotics but not metronidazole improved the acute pancreatitis‐induced increase in endotoxemia and transaminase levels. The addition of alcohol worsened these variables to a limited extent in the synbiotic‐treated group, while metronidazole had a negative effect on liver damage. CONCLUSIONS: Gut flora pretreatment with synbiotics was able to effectively protect against endotoxin/bacterial translocation, as well as liver damage in the course of acute pancreatitis and concomitant heavy alcohol consumption. The beneficial effect of synbiotics on liver histology seems to be correlated with endotoxemia. Metronidazole did not produce such a beneficial effect; in fact, it further worsened liver damage when alcohol was added to the background of ongoing acute pancreatic inflammation. 相似文献

Objective:
During the perioperative period, oral ingestion is changed considerably in esophagectomy patients. The aim of this study was to investigate oral environment modifications in patients undergoing esophageal cancer treatments due to changes in dietary intake and swallowing functions.Material and Methods:
Thirty patients who underwent operation for removal of esophageal cancer in Tokushima University Hospital were enrolled in this study.Results:
It was found that 1) the flow rate of resting saliva decreased significantly at postoperative period by deprived feeding for one week, although it did not recover several days after oral ingestion began, 2) the accumulation of dental plaque and the number of mutans streptococci in saliva decreased significantly after operation, while both increased relatively quick when oral ingestion began, and 3) the swallowing function decreased significantly in the postoperative period.Conclusions:
These results suggest that dental professionals should emphasize the importance of oral health care and provide instructions on plaque control to patients during the perioperative period of esophageal cancer treatment. 相似文献8.

We describe a rare case where a patient developed intracranial pial arteriovenous (AV) fistula due to dural tenting. The patient was a 63-year-old woman who had undergone neck clipping for an unruptured middle cerebral artery (MCA) aneurysm. The surgery was performed without any problems and her postoperative course was uneventful. Two weeks after cerebral angiography operation revealed a pial AV fistula fed by the right MCA and drained into the vein of Trolard through the Sylvian vein which had not existed before surgery. Being diagnosed as de novo pial AV fistula, surgical repair was performed. The AV fistula was located just beneath the dural tenting. The fistulous point was confirmed with fluorescein video angiography and obliterated using a clip. Although rare, we should pay attention to the AV fistula due to dural tenting as the complications of cranial surgery. 相似文献

A 4 month old female infant with atypical asymmetrical massive gray matter heterotopia diagnosed as West syndrome is described. Her seizure initially appeared as afebrile general tonic and clonic convulsion and progressed to typical West syndrome consisting of clusters of myoclonic spasms of the extremities, mainly on the left side, accompanied by head and eye deviation to the right side. Electroencephalogram (EEG) presented typical hypsarrhythmia and cranial computerized tomography (CT) and magnetic resonance imaging (MRI) showed massive heterotopic gray matter in the right hemisphere with the same density or intensity as cortical gray matter. Single photon emission computed tomography (SPECT), using N-isopropyl-p-123I-iodoamphetamine (123I-IMP), demonstrated decreased blood flow in the ectopic lesion. Although clinical response to several anti-epileptic drugs was poor, her seizures were well controlled by relatively low dose adrenocorticotropic hormone (ACTH) therapy of 0.015 mg/kg per day followed by a combination of valproic acid and clonazepam. 相似文献

This study reports an unusual case of acute leukemia which was diagnosed as hemophilia A on initial admission for leukemia. A 3 year old boy was admitted to Kagoshima University Hospital with anemia. He was diagnosed as acute lymphoblastic leukemia. At the same time he was revealed to have severe hemophilia A− without any previous episodes of severe bleeding tendency or family history of this disease. The laboratory investigation showed his mother to be a carrier of hemophilia A. Although there are many cases of hemophilia which have developed malignant tumors, most of them were caused by association with human immunodeficiency virus (HIV) infection. Only five cases with coexistence of leukemia and hemophilia without HIV infection have been reported and the present case is the first one in Japan. At this stage, hemophiliacs are not necessarily regarded to be a population at risk for the development of leukemia. Furthermore, no particular subtype of leukemia was characterized among these patients in the literature. 相似文献
