Blood oxidative stress markers are unreliable markers of hepatic steatosis.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) and viral hepatitis are associated with hepatic oxidative stress, which is partially dependent on the amount of hepatic fat. AIM: To determine whether the circulating lipid and oxidative stress parameters could be non-invasive markers of hepatic steatosis. METHODS: Sixty-four patients with NAFLD or viral hepatitis were tested for lipid peroxidation products and antioxidant defence systems, lipid parameters and liver function tests. RESULTS: Hepatic steatosis was correlated with lipids, gamma-glutamyltranspeptidase, thiobarbituric acid-reactive substances, superoxide dismutase and superoxide dismutase/erythrocyte glutathione peroxidase ratio. gamma-Glutamyltranspeptidase, triglycerides and low-density lipoprotein cholesterol were significantly higher in the presence of steatosis. No difference in blood oxidative stress markers was observed according to the presence or absence of steatosis except for the superoxide dismutase/erythrocyte glutathione peroxidase ratio. Total cholesterol, triglycerides and low-density lipoprotein cholesterol were significantly higher in the NAFLD group (n = 17, 60% mean steatosis grade) than in the viral hepatitis group (n = 20, 13% mean steatosis grade). Only superoxide dismutase was lower and vitamin E higher in NAFLD than in viral hepatitis patients. CONCLUSIONS: Standard blood oxidative stress markers do not predict the extent of hepatic steatosis as they probably do not accurately reflect intrahepatic oxidative stress. Serum lipid levels were best correlated with hepatic steatosis.

[MALT-type B-cell lymphoma masquerading as scleritis or posterior uveitis].

PURPOSE: Diagnostic and therapeutic management of masquerade syndromes associated with MALT-type lymphoma. PATIENTS AND METHOD: We report the cases of three patients referred for acute or chronic severe loss of visual acuity. All of them suffered from uveitis or scleritis resistant to corticoid treatment. Each one had posterior uveitis associated with retinochoroidal infiltration, anterior scleritis associated with uveal effusion syndrome, or bilateral pan-uveitis associated with serous retinal detachment. Two patients had medical records of systemic malignancies. They underwent an extensive work-up. Search for an infectious, immune or malignant disease was negative but orbital imaging showed a posterior scleral thickening in all cases. RESULTS: Diagnosis of mucosa-associated lymphoid tissue (MALT) ocular lymphoma was assessed in all cases after scleral biopsy. Immunohistochemical analysis showed CD20(+) and CD5(-) scleral lymphocyte infiltrates. The three patients underwent chemotherapy associated with radiotherapy. Lesions were stabilized in the first case, whereas six lines of visual acuity improvement was noted in the second one, and full recovery was achieved after treatment in the third case. DISCUSSION: Clinical manifestations of this ocular lesion seem to be multiple, masquerading as different types of posterior uveitis or scleritis. In the three cases, we did found other systemic locations of MALT-type lymphoma. Diagnosis was mainly based on pathological analysis. Fast visual recovery in two cases demonstrated the importance of an early diagnosis and a specific treatment. All cases of chronic and corticoid-resistant posterior uveitis require a specialized radiological evaluation followed, if necessary, by multiple orbital biopsies.

Lower expression of CD81 B-cell receptor in lymphoproliferative diseases associated with hepatitis C virus infection.

Chronic hepatitis C virus (HCV) infection is frequently associated with type II mixed cryoglobulinaemia (MC), a benign lymphoproliferative disease (LPD). More recently, HCV has been implicated as a possible aetiologic factor of B-cell non-Hodgkin lymphoma (B-NHL). CD81, a B-cell surface receptor, has been proposed as a receptor for HCV binding and entry in circulating B cells. The stimulation of CD81 complex enables B cells to respond to lower concentrations of antigen and finally induces B-cell proliferation. We studied the phenotypic expression of CD81, CD19 and CD5 on circulating B cells in HCV patients LPD-positive or LPD-negative. Sixty-two patients were anti-HCV antibody positive. Among HCV positive patients, 44 were HCV RNA positive with an histologically proven chronic active hepatitis of whom 10 had a B-NHL, 14 an MC and 24 no extrahepatic manifestation. Eighteen patients were HCV RNA negative with evidence of resolved infection. A control group included 40 healthy subjects. Peripheral blood mononuclear cells (PBMC) were stained for surface expression of CD81, CD19 and CD5 using monoclonal antibodies, and were analyzed by flow cytometry. The percentage of PBMC expressing CD81, CD19 and CD5 receptors were compared between the groups by univariate analysis. Logistic regression model variables were then evaluated to correlate the presence of an LPD with HCV infection characteristics (i.e. age, gender, genotype, duration of infection, HCV RNA positivity, liver histological lesions), or phenotypic expression of CD81, CD19 and CD5 receptors on PBMC. HCV antibody-positive compared with HCV-negative subjects had a higher expression of CD19 receptor (23 +/- 13 vs 13 +/- 1%, P = 0.003). Among HCV RNA positive-patients, LPD+ compared with LPD- patients had a lower expression of CD81 (58 +/- 28 vs 82 +/- 18%, P = 0.001) and CD5 receptor (66 +/- 16 vs 74 +/- 13%, P = 0.04). In multivariate analysis, the expression of CD81 receptor was a negative (OR = 0.15, 95% CI = 0.04-0.64, P = 0.01) and CD19 receptor a positive (OR = 4.81, 95% CI =1.29-17.88, P = 0.02) predictive factor for an LPD. We found two negative predictive factors for HCV RNA positivity, i.e. age (OR = 0.23, 95% CI. = 0.08-0.62, P = 0.003) and the expression of CD81 receptor (OR = 0.34, 95% CI = 0.13-0.89, P = 0.02). In patients with a chronic active HCV infection, the presence of a lymphoproliferative disease, either MC or B-NHL, is associated with lower expression of CD81 and higher expression of CD19 receptor on peripheral B cells.

Tumour stage, node stage, p53 gene status, and bcl-2 protein expression as predictors of tumour response to platin-fluorouracil chemotherapy in patients with squamous-cell carcinoma of the head and neck.

The purpose of this study was to establish the relative contribution of tumour stage, node stage, p53 gene status, p53 expression, and bcl-2 protein expression to tumour response to platin-fluorouracil chemotherapy in 141 patients with squamous-cell carcinomas of the head and neck. Tumour response was measured at the primary site after three cycles of chemotherapy. Exons 2-10 and the coding part of exon 11 were sequenced on both strands. Bcl-2 or p53 expression was detected by immunohistochemistry. Predictor variables of objective response (reduction of at least 50% of tumour size) were tested in univariate and multivariate analyses. P53 mutations were found in 52 patients (37%). Tumour cells expressed p53 in 84 cases (59%) and bcl-2 in 25 cases (18%). T1 or T2 stage (adjusted odds ratio, 3.3; 95% confidence interval 1.3-8.7; P=0.01), N0 node stage (adjusted odds ratio, 2.7; 95% confidence interval 1.1-6.4; P=0.03), p53 wild-type gene (adjusted odds ratio, 4.0; 95% confidence interval 1.7-9.5; P=0.002), and bcl-2 protein expression (adjusted odds ratio, 20; 95% confidence interval 2.3-170; P=0.006), were positively associated with tumour response. P53 protein expression was not predictive of response. In conclusion, tumour stage, node stage, p53 gene status, and bcl-2 expression are independent predictors of tumour response to platin-fluorouracil in patients with squamous-cell carcinomas of the head and neck.

Fatigue in patients with chronic hepatitis C.

In numerous studies of symptoms in patients with chronic hepatitis C there has been no systematic assessment of both fatigue and extrahepatic manifestations. Our objective was to assess the prevalence of fatigue in patients with hepatitis C virus (HCV) infection, and to identify associations between fatigue and clinical and biological hepatic and extrahepatic manifestations. We studied 1614 patients. Data were prospectively recorded during the first visit of patients infected with HCV and the prevalence of fatigue and its association with dermatological, rheumatological, neurological and nephrological manifestations; diabetes; arterial hypertension; auto-antibodies, and cryoglobulinaemia were assessed. Then, using multivariate analysis, we identified demographic, biochemical, immunological, virological, and histological factors associated with the presence of fatigue. Fatigue was present in 53% of patients (95% confidence interval 51-56). In 17% of patients (95% confidence interval 15-19) fatigue was severe, impairing activity. Five other extrahepatic manifestations had a prevalence above 10% including, in decreasing order: arthralgia, paresthesia, myalgia, pruritus, and sicca syndrome. In univariate and multivariate analyses, fatigue, in comparison with the absence of fatigue, was associated with female gender, age over 50 years, cirrhosis, depression and purpura. Independent of these associations, fatigue was associated with arthralgia, myalgia, paresthesia, sicca syndrome and pruritus. The prevalence of fibromyalgia (as defined by the association of fatigue with arthralgia or myalgia) was 19% (95% confidence interval 17-21). There was no significant association between fatigue and the following characteristics: viral load or genotype, alcohol consumption, abnormal thyroid function, and type and level of cryoglobulinaemia. Hence, fatigue is the most frequent extrahepatic manifestation in patients infected with HCV. Fatigue is independently associated with female gender, age over 50 years, cirrhosis, depression and purpura.

Changes in AIDS-related lymphoma since the era of highly active antiretroviral therapy.

HIV infection is associated with a high incidence of AIDS-related lymphomas (ARLs). Since the use of highly active antiretroviral therapy (HAART), the incidence of AIDS-defining illnesses has decreased, leading to a significant improvement in survival of HIV-infected patients. The consequences of HAART use on ARL are under debate. This study compared the incidence and the characteristics of ARL before and after the use of HAART in a large population of HIV-infected patients in the French Hospital Database on HIV (FHDH) and particularly in 3 centers including 145 patients with proven lymphoma. Within the FHDH, the incidence of systemic ARL has decreased between 1993-1994 and 1997-1998, from 86.0 per 10 000 to 42.9 per 10 000 person-years (P < 10(-30)). The incidence of primary brain lymphoma has also fallen dramatically between the periods, from 27.8 per 10 000 to 9.7 per 10 000 person-years (P < 10(-11)). The analysis of 145 cases of ARL in 3 hospitals showed that known HIV history was longer in the second period than in the first period among patients with systemic ARL (98 versus 75 months; P <.01). Patients had a higher number of CD4 cells at diagnosis during the second period (191 versus 63/microL, P = 10(-3)). Survival of patients with systemic ARL also increased between the periods (from 6 to 20 months; P =.004). Therefore, the profile of ARL has changed since the era of HAART, with a lower incidence of systemic and brain ARL. The prognosis of systemic ARL has improved.

Biochemical markers of liver fibrosis in patients with hepatitis C virus infection: a prospective study.

BACKGROUND: Liver biopsy is thought mandatory for management of patients with hepatitis C virus (HCV) infection, especially for staging fibrosis. We aimed, in our prospective study, to assess the predictive value of a combination of basic serum biochemical markers for diagnosis of clinically significant fibrosis (including early stages). METHODS: We assessed liver-biopsy patients with detectable HCV by PCR, for eligibility, and took a blood sample on the day of the procedure. The analysis was done in a first-year period for 205 patients and then tested in a second period on 134 patients. We devised a fibrosis index that included the most informative markers (combined with age and sex) for the first-year group. 11 serum markers were assessed as well as fibrosis stage: F0=no fibrosis and F1=portal fibrosis; and for clinically significant fibrosis, F2=few septa, F3=many septa, and F4=cirrhosis. Statistical analysis was by logistic regression, neural connection, and receiver-operating characteristic (ROC) curves. FINDINGS: First-year and second-year patient-group characteristics and biochemical markers did not differ. The overall frequency of clinically significant fibrosis was 40% (138 patients). The most informative markers were: alpha2 macroglobulin, alpha2 globulin (or haptoglobin), gamma globulin, apolipoprotein A1, gamma glutamyltranspeptidase, and total bilirubin. The areas (SD) under the ROC curves for the first-year (0.836 [0.430]) and second-year groups (0.870 [0.340]) did not differ (p=0.44). With the best index, a high negative predictive value (100% certainty of absence of F2, F3, or F4) was obtained for scores ranging from zero to 0.10 (12% [41] of all patients), and high positive predictive value (>90% certainty of presence of F2, F3, or F4) for scores ranging from 0.60 to 1.00 (34% [115] of all patients). INTERPRETATION: A combination of basic serum markers could be used to substantially reduce the number of liver biopsies done in patients with chronic HCV infection.

Identification of prognostic factors in 61 patients with posttransplantation lymphoproliferative disorders.

PURPOSE: Prognostic studies of posttransplantation lymphoproliferative disorders (PTLDs) are hindered by the small number of cases at each transplant center. We analyzed prognostic factors and long-term outcome according to clinical manifestations, pathologic features, and treatment and investigated the prognostic value of the non-Hodgkin's lymphoma International Prognostic Index (IPI) in 61 patients with PTLD. PATIENTS AND METHODS: We studied 61 patients in two institutions who developed PTLD and analyzed factors influencing the complete remission and survival rates. RESULTS: In univariate analysis, factors predictive of failure to achieve complete remission were performance status (PS) > or = (P =.0001) and nondetection of Epstein-Barr virus (EBV) in the tumor (P =.01). Only a negative link with PS > or = 2 was observed in multivariate analysis. In univariate analysis, factors predictive of lower survival were PS > or = 2, the number of sites (one v > one), primary CNS localization, T-cell origin, monoclonality, nondetection of EBV, and treatment with chemotherapy. The IPI failed to identify a patient subgroup with better survival and was less predictive of the response rate than was a specific index using two risk factors (PS and number of involved sites), which defined three groups of patients: low-risk patients whose median survival time has not yet been reached, intermediate-risk patients with a median survival time of 34 months, and high-risk patients with a median survival time of 1 month. CONCLUSION: PS and the number of involved sites defined three risk groups in our population. The value of these prognostic factors needs to be confirmed in larger cohorts of patients treated in prospective multicenter studies.

Influence of HLA-DR phenotype on the risk of hepatitis C virus-associated mixed cryoglobulinemia.

OBJECTIVE: Circumstances predisposing hepatitis C virus (HCV)-infected patients to develop mixed cryoglobulinemia (MC), which may manifest as a small-vessel systemic vasculitis (MC vasculitis), remain unclear. Previous studies have failed to demonstrate a clear role of either viral factors (genotype, viral load) or host factors (lymphocytes or immunoglobulin subsets). This study was undertaken to examine a possible role of HLA class II alleles in HCV-associated MC. METHODS: One hundred fifty-eight HCV-infected patients, of whom 76 had MC (56 with type II MC and 20 with type III MC) and 82 did not have MC, were studied prospectively. MC vasculitis was noted in 35 HCV-infected patients with type II IgMkappa-containing cryoglobulins. HLA-DRB1 and HLA-DQB1 polymorphism was analyzed by hybridization using allele-specific oligonucleotides, after gene amplification. The odds ratio (OR) was calculated with Woolf's method. Then, using multivariate analysis, demographic, biologic, immunologic, virologic, and liver histologic factors associated with the presence of MC and MC vasculitis were investigated. RESULTS: HLA-DR11 was significantly more frequent in patients with type II MC than in those without MC (41.1% versus 17.1%; OR 3.4, corrected P [Pcorr] = 0.017), regardless of the presence of vasculitis accompanying the MC (37.1% of those with MC vasculitis, 34.1% of those with MC but no vasculitis). HLA-DR7 was less frequent in HCV-infected patients with MC than in those without MC (13.2% versus 30.5%; OR 0.34, P = 0.012, Pcorr not significant), with a particularly lower frequency in those with type II MC and those with MC vasculitis (12.5% and 8.6%, respectively). There was no significant difference in HLA-DQB1 distribution between the different patient groups. By univariate and multivariate analysis, HLA-DR11 was the only positive predictive factor, besides female sex and advanced age, for the presence of MC and HCV-associated MC vasculitis (OR 2.58). CONCLUSION: Our results indicate that the presence of the DR11 phenotype is associated with a significantly increased risk for the development of type II MC in patients with chronic HCV infection. In contrast, HLA-DR7 appears to protect against the production of type II MC. These results suggest that the host's immune response genes may play a role in the pathogenesis of HCV-associated MC.

Rates and risk factors of liver fibrosis progression in patients with chronic hepatitis c.

BACKGROUND AIMS: In hepatitis C there is controversy over the linearity of the rate of progression and the significance of gender, mode of infection and viral factors. METHODS: 2313 untreated patients with a reliable estimated duration of infection and liver fibrosis were included. Fibrosis progression was calculated using the Kaplan-Meier method and the rate of fibrosis progression using the hazard function. Seven risk factors were assessed: age at biopsy, gender, alcohol consumption, mode of infection, activity grade, hepatitis C virus genotype and RNA level. RESULTS: The percentage of patients without cirrhosis was 91% after 20 years of infection (95% CI:90-92%) and 56% after 40 years (95% CI:48-64%). Three independent factors were associated (P < 0.001) with a faster progression rate: age at infection, alcohol consumption of 50 g or more per day, and male gender. The mode of infection, histologic activity, genotype and viral load were not independently associated with fibrosis. Fibrosis progression was mainly dependent on age and the duration of infection and can be divided into four successive periods with very slow, slow, intermediate and rapid progression rates. CONCLUSION: In patients infected with hepatitis C, the majority of fibrosis progression occurred in those aged fifty years or older.

[Pulmonary hyalinising granuloma: report of 2 original cases with cervicofacial and orbital involvement].

INTRODUCTION: Pulmonary hyalinizing granuloma is a rare fibrosing nodular disease of the lung characterized by its histological appearance, which includes at the center of the lesion a dense network of concentric hyalinized collagen lamella surrounded by perivascular lymphoplasmacytic infiltrate that rarefies in the center of the nodule. EXEGESIS: We report two new cases: the first with laryngeal (endoluminal tumor-like), orbital (subeyelid nodule) and mesenteric (9 x 6 cm mass) location of hyalinizing granuloma; the second with cervical, facial (trismus), orbital (pseudotumor) and limb (ankylosing elbow) fibrosis. CONCLUSION: The extrapulmonary diffusion of the disease is extremely rare. In one of the cases, with corticosteroids and after a follow-up of 12 months, the pulmonary tumors vanished but the fibrosis resolved only partially.

Bone marrow involvement in lymphomas with hemophagocytic syndrome at presentation: a clinicopathologic study of 11 patients in a Western institution.

Hemophagocytic syndrome (HPS) is a clinicopathologic syndrome that can reveal a non-Hodgkin's lymphoma. The pathologic features of lymphoma associated with HPS remain ill defined. We studied 11 lymphomas associated with HPS on initial bone marrow biopsies, consecutively diagnosed during a 6-year period in a Western institution. There were seven diffuse large B-cell lymphomas (DLBCLs), three T-cell lymphomas (one peripheral T-cell lymphoma unspecified, two hepatosplenic gammadelta T-cell lymphomas [HS gammadeltaTLs]), and one aggressive NK-cell lymphoma/leukemia (NKL). These lymphomas shared common clinicopathologic features with a systemic presentation, a poor outcome (nine patients died within 2 years), and a mild interstitial lymphoid infiltrate of the bone marrow at presentation in nine patients. This equivocal lymphoma infiltrate was blending with normal hematopoietic cells, and CD20 and CD3 immunolabelings were essential for its detection. A high number of reactive T (CD3+) cells, most often with a predominant cytotoxic (CD8+ TiA1+) phenotype, was present in all DLBCLs. By in situ hybridization, Epstein-Barr virus was detected in neoplastic cells of three cases (one DLBCL, one HS gammadeltaTL, and one NKL), which also showed serum viral DNA. Polymerase chain reaction studies disclosed HHV6 DNA sequences in tumor tissues of two DLBCLs, whereas HHV8 DNA was not detected. Because tumor mass indicative of lymphoma was not striking in most patients, bone marrow biopsy appears to be of great value for the diagnosis of an HPS-associated lymphoma, which may be, in Western patients, of B- as well as T- or NK-cell type. Immunostaining for CD3 and CD20 is essential to identify the common subtle lymphoma involvement. Together with a better understanding of the pathogenic processes, an early diagnosis may improve the prognosis of HPS-associated lymphoma.

Preservation of graft-versus-infection effects after suicide gene therapy for prevention of graft-versus-host disease.

The main complications following allogeneic hematopoietic stem cell transplantation are graft-versus-host disease and poor immune reconstitution leading to severe infections. Mature donor T cells present in the transplant facilitate T cell reconstitution in adults, but also induce graft-versus-host disease, which itself impairs immune reconstitution. Thus, infusing a large number of donor T cells with a diverse repertoire should accelerate functional immune reconstitution after transplantation, only if graft-versus-host disease can be controlled. We previously demonstrated that preventive treatment with ganciclovir could control graft-versus-host disease in mice if donor T cells are made to express viral thymidine kinase as a "suicide" gene. Here we evaluated the recovery of functional antiviral immune responses in such mice. Irradiated mice received an allogeneic hematopoietic stem cell transplantation with thymidine kinase-expressing T cells and were protected from graft-versus-host disease by ganciclovir treatment, and then challenged with lymphocytic choriomeningitis virus. Grafted mice could mount efficient antilymphocytic choriomeningitis virus immune responses leading to viral elimination. Furthermore, when transplanted cells were obtained from mice previously immunized against lymphocytic choriomeningitis virus, grafted mice developed memory-type accelerated responses against the virus. We conclude that efficient graft-versus-infection effects can be mediated by naive T cells and memory donor T cells that persist after suicide gene therapy for prevention of graft-versus-host disease.

Expression of p16/INK4a in posttransplantation lymphoproliferative disorders.

It was recently demonstrated that classification of posttransplantation lymphoproliferative disorders (PT-LPDs) into morphological and molecular categories is clinically relevant. It was also reported that PT-LPD not associated with Epstein-Barr virus (EBV) had a more aggressive course than most lesions associated with EBV. Because the cyclin-dependent kinase inhibitor p16/INK4a has been reported to be frequently inactivated in high-grade lymphomas, we evaluated 17 PT-LPD to determine whether p16/INK4a expression could be correlated to morphology, EBV detection, and a Ki-67 labeling index. We demonstrated that tumors with no p16/INK4a expression (n = 8) had a predominantly monomorphic appearance, and most were EBV negative (respectively, 7/8 and 5/8), whereas lesions with p16/INK4a expression (n = 9) were mostly polymorphic PT-LPD (6/9) (P = 0.049) and associated with EBV (9/9) (P = 0.015). In particular, strong p16/INK4a expression was observed in atypical immunoblasts and Reed-Sternberg-like cells. Furthermore, the proliferation index was significantly higher in tumors lacking p16/INK4a expression than in other lesions (P = 0.0008). In conclusion, down-regulation of p16/INK4a was mostly observed in PT-LPD lesions known to follow more aggressive courses: monomorphic tumors and EBV-negative PT-neoplasms. Conversely, overexpression of p16/INK4a was associated with EBV-positive PT-LPD. While p16/INK4a might play a role in the proliferative rate of LP-LPD, further investigations are needed to assess the clinical relevance of p16/INK4a expression in predicting the evolution of tumors and to explain how EBV could favor p16/INK4a protein accumulation in lesions.

Liver fibrosis in overweight patients.

BACKGROUND & AIMS: A common clinical issue is whether overweight patients with abnormal liver function test results should undergo liver biopsy. Although serious liver injury can occur, its prevalence and risk factors are not well known. METHODS: Ninety-three consecutive patients with abnormal liver function tests (but without overt liver disease), body mass index (BMI) > 25 kg/m(2), and no alcoholic, viral, autoimmune, drug-induced, or genetic liver disease were retrospectively studied. Clinical, biological, and histological variables were tested for association with septal fibrosis or cirrhosis. RESULTS: Septal fibrosis was present in 28 patients (30%) including cirrhosis in 10 (11%). Age >/= 50 years (odds ratio [OR], 14.1), BMI >/= 28 kg/m(2) (OR, 5.7), triglycerides >/= 1.7 mmol/L (OR, 5), and alanine aminotransferase (ALT) >/= 2N (OR, 4.6) were independently associated with septal fibrosis. Among histological features, septal fibrosis was strongly associated with necroinflammatory activity (OR, 44). A score combining age, BMI, triglycerides, and ALT had 100% negative predictive value for septal fibrosis when scoring 0 or 1 (100% sensitivity for a specificity of 47%). CONCLUSIONS: Septal fibrosis occurs frequently in overweight patients with abnormal liver function tests. A clinicobiological score combining BMI, age, ALT, and triglycerides could improve selection of patients for liver biopsy.
