Changes on chest HRCT in systemic sclerosis-related interstitial lung disease after autologous haematopoietic stem cell transplantation.

OBJECTIVE: To evaluate extent of interstitial lung disease (ILD) and oesophageal involvement using high-resolution computed tomography (HRCT) in early diffuse SSc patients after autologous haematopoietic stem cell transplantation (aHSCT). METHODS: Overall chest HRCT, lung function and skin score changes were evaluated in 33 consecutive diffuse SSc patients before and after aHSCT during yearly routine follow-up visits between January 2000 and September 2016. Two independent radiologists blindly assessed the ILD extent using semi-quantitative Goh and Wells method, the widest oesophageal diameter (WOD) and the oesophageal volume (OV) on HRCT. Patients were retrospectively classified as radiological responders or non-responders, based on achieved stability or a decrease of 5% or more of HRCT-ILD at 24 months post-aHSCT. RESULTS: Using a linear mixed model, the regressions of the extent of ILD and of ground glass opacities were significant at 12 months (ILD P = 0.001; ground glass opacities P = 0.0001) and at 24 months (ILD P = 0.007; ground glass opacities P = 0.0008) after aHSCT, with 18 patients classified as radiological responders (probability of response 0.78 [95% CI 0.58, 0.90]). Meanwhile the WOD and the OV increased significantly at 12 months (WOD P = 0.03; OV P = 0.34) and at 24 months (WOD P = 0.002; OV P = 0.007). Kaplan-Meier analyses showed a trend towards better 5-year survival rates (100% vs 60%; hazard ratio 0.23 [95% CI 0.03, 1.62], P = 0.11) among radiological responders vs non-responders at 24 month follow-up after aHSCT. CONCLUSION: Real-world data analysis confirmed significant improvement in extent of HRCT SSc-ILD 24 months after aHSCT, although oesophageal dilatation worsened requiring specific attention.

A cross-sectional study of 502 patients found a diffuse hyperechoic kidney medulla pattern in patients with severe gout.

We have previously shown that ultrasonography can detect hyperechogenic crystal deposits in the kidney medulla of patients with gout. In this cross-sectional study we investigated the frequency and clinical correlates of hyperechogenic kidney medulla in 502 consecutive primary consultants for gout (ACR/EULAR criteria) at the Vien Gut medical center in Ho Chi Minh City, Vietnam. None of these patients received urate-lowering drugs. Kidney medulla echogenicity on B-mode ultrasonography was compared to that of the kidney cortex. Overall, 36% patients showed a hyperechoic pattern of Malpighi pyramids. On univariate analysis, the pattern was significantly associated with age, estimated gout duration, steroid-dependency, clinical tophi, urate arthropathy, double contour thickness at the scanned joints, coronary heart disease, arterial hypertension, hyperuricemia, proteinuria, leukocyturia, and decreased estimated glomerular filtration rate. On multivariable analysis, the hyperechoic pattern was associated with estimated disease duration, clinical tophi, urate arthropathy, double contour thickness and decreased estimated glomerular filtration rate. No hyperechoic pattern was observed in 515 consecutive consultants without gout. Thus, hyperechoic kidney medulla was frequently demonstrated in Vietnamese patients with tophaceous gout and associated with features of tubulointerstitial nephritis. This finding revives the hypothesis of microcrystalline nephropathy of gout, predominantly seen in untreated gouty patients, which could be an important target for urate-lowering therapy.

Efficacy of tocilizumab in Takayasu arteritis: Multicenter retrospective study of 46 patients.

OBJECTIVES: To assess the efficacy of tocilizumab in patients with Takayasu arteritis (TA). METHODS: We conducted a retrospective multicenter study in 46 TA patients treated with tocilizumab. We analyzed factors associated with response to tocilizumab (assessed using NIH score). RESULTS: Forty-six patients with TA were included, with a median age of 43 years [29-54], and 35 (76%) females. We observed a decrease in the median NIH scale (from 3 [2-3] at baseline to 0 [0-1] and 0 at 3 and 6 months, respectively; p < 0.0001). The daily prednisone dose also decreased from 15 mg [8-19] at baseline to 4 mg [5-21] and 5 mg [4.5-9] at 3 and 6 months, respectively (p < 0.0001) under tocilizumab. The overall tocilizumab failure free survival was 81% [CI 95%; 0.7-0.95], 72% [CI 95%; 0.55-0.95] and 48% [CI 95%; 0.2-0.1] at 12, 24 and 48 months, respectively. The presence of constitutional symptoms (HR 5.6 [CI 95%; 1.08-29], p = 0.041), and C-reactive protein level (HR 1.16 [CI 95%; 1.01-1.31], P = 0.003) at the time of tocilizumab initiation were significantly associated with tocilizumab event-free survival. The event-free survival was significantly better under tocilizumab therapy in comparison to DMARDs (p = 0.02). CONCLUSION: This large multicenter study shows that tocilizumab is efficient and may reduce the incidence of relapses in TA.

Efficacy of Biological-Targeted Treatments in Takayasu Arteritis: Multicenter, Retrospective Study of 49 Patients.

BACKGROUND: The goal of this work was to assess the safety and efficacy of biologics (ie, tumor necrosis factor-α antagonists and tocilizumab) in patients with Takayasu arteritis. METHODS AND RESULTS: This was a retrospective, multicenter study of the characteristics and outcomes of 49 patients with Takayasu arteritis (80% female; median age, 42 years [20-55 years] treated by tumor necrosis factor-α antagonists [80%] or tocilizumab [20%]) and fulfilling American College of Rheumatology or Ishikawa criteria. Factors associated with complete response were assessed. Eighty-eight percent of patients with Takayasu arteritis were inadequately controlled with or were intolerant to conventional immunosuppressive therapy (median number, 3 [1-5]). Overall response (ie, complete and partial) to biological-targeted treatments at 6 and 12 months was 75% and 83%, respectively. There were significantly lower C-reactive protein levels at the initiation of biological-targeted treatments (22 mg/L [10-46 mg/L] versus 58 mg/L [26-76 mg/L]; P=0.006) and a trend toward fewer immunosuppressants drugs used before biologics (P=0.054) in responders (ie, complete or partial responders) relative to nonresponders to biological-targeted treatments. C-reactive protein levels and daily prednisone dose significantly decreased after 12 months of biological-targeted treatments (30 versus 6 mg/L [P<0.05] and 15 versus 7.5 mg [P<0.05] at baseline and 12 months, respectively). The 3-year relapse-free survival was 90.9% (83.5%-99%) over the biological treatment period compared with 58.7% (43.3%-79.7%; P=0.0025) with disease-modifying antirheumatic drugs. No difference in efficacy was found between tumor necrosis factor-α antagonists and tocilizumab. After a median follow-up of 24 months (2-95 months), 21% of patients experienced adverse effects, with biological-targeted treatments discontinued in 6.6% of cases. CONCLUSION: This nationwide study shows a high efficacy of biological-targeted treatments in refractory patients with Takayasu arteritis with an acceptable safety profile.

Retrospective analysis of surgery versus endovascular intervention in Takayasu arteritis: a multicenter experience.

BACKGROUND: With recent advances in endovascular treatment, percutaneous endoluminal angioplasty has become particularly attractive for arterial lesions of Takayasu arteritis. However, data came from case reports or small series, and the long-term outcome has not been reported. The incidence of potential vascular complications after surgery or endovascular treatment is still to be determined. METHODS AND RESULTS: This retrospective multicenter study analyzed the results and outcomes of 79 consecutive patients with Takayasu arteritis (median age, 39 years; interquartile range [IQR], 25-50 years; 63 women [79.7%]) who underwent 166 vascular procedures (surgery, 104 [62.7%]; endovascular repair, 62 [37.3%]) for the management of arterial complications. After a follow-up of 6.5 years (IQR, 2.2-11.5 years), 70 complications were observed, including restenosis (n=53), thrombosis (n=7), bleeding (n=6), and stroke (n=4). The overall 1-, 3-, 5-, and 10-year arterial complication-free survival rates were 78% (IQR, 69%-88%), 67% (IQR, 57%-78%), 56% (IQR, 46%-70%), and 45% (IQR, 34%-60%), respectively. Among the 104 surgical procedures, 39 (37.5%) presented a complication compared with 31 of the 62 (50%) with endovascular repair. In multivariate analysis, biological inflammation at the time of revascularization (odds ratio, 7.48; 95% confidence interval, 1.42-39.39; P=0.04) was independently associated with the occurrence of arterial complications after the vascular procedure. Patients who experienced complications had higher erythrocyte sedimentation rates (P<0.001) and C-reactive protein (P<0.001) and fibrinogen (P<0.005) serum levels compared with those without complications. CONCLUSIONS: The overall 5-year arterial complication rate was 44%. Biological inflammation increased the likelihood of complications after revascularization in patients with Takayasu arteritis.

Rituximab plus Peg-interferon-alpha/ribavirin compared with Peg-interferon-alpha/ribavirin in hepatitis C-related mixed cryoglobulinemia.

Treatment of hepatitis C (HCV)-mixed cryoglobulinemia (MC) may target either the viral trigger (HCV) or the downstream B-cell clonal expansion. Prospective cohort study of 38 HCV-MC patients who received a combination of rituximab (375 mg/m(2)) once a week for 1 month followed by Peg-interferon-alpha (Peg-IFN-alpha; 2a, 180 microg or 2b, 1.5 microg/kg) weekly plus ribavirin (600-1200 mg) daily for 48 weeks were compared with 55 HCV-MC patients treated by Peg-IFN-alpha/ribavirin with the same modalities. In the whole population of HCV-MC patients (n = 93), a complete clinical response was achieved in 73.1% (68 of 93), cryoglobulin clearance in 52.7% (49 of 93), and a sustained virologic response in 59.1% (55 of 93). Compared with Peg-IFN-alpha/ribavirin, rituximab plus Peg-IFN-alpha/ribavirin-treated patients had a shorter time to clinical remission (5.4 +/- 4 vs 8.4 +/- 4.7 months, P = .004), better renal response rates (80.9% vs 40% of complete response, P = .040), and higher rates of cryoglobulin clearance (68.4% vs 43.6%, P = .001) and clonal VH1-69(+) B-cell suppression (P < .01). Treatment was well tolerated with 11% of discontinuation resulting from antiviral therapy and no worsening of HCV RNA under rituximab. Our findings indicate that rituximab combined with Peg-IFN-alpha/ribavirin is well tolerated and more effective than Peg-IFN-alpha/ribavirin in HCV-MC.

Cryoglobulinaemia vasculitis in patients coinfected with HIV and hepatitis C virus.

OBJECTIVE: To describe mixed cryoglobulinaemia (MC) vasculitis in patients coinfected with hepatitis C virus (HCV) and HIV. DESIGN: Retrospective multicentre study through the GERMIVIC Database of 4005 HIV/HCV-coinfected patients. METHODS: The characteristics and outcome of 11 HIV/HCV-coinfected patients with MC vasculitis were analysed and compared with those of 118 HCV-infected patients with MC vasculitis. RESULTS: The mean age was 46 years (SD, 14), with 82% male. The median initial CD4 cell count was 367 cells/microl (range, 252-846). After a mean follow-up of 44.4 months, two deaths (18%) were noted. Clinical manifestations of MC included polyneuropathy in seven (64%), purpura in four (36%), arthralgia in four (36%), and kidney involvement in three (27%). Six patients received combination treatment with interferon-alfa and ribavirin, three of whom had sustained HCV virological response and were complete clinical responders. Four patients received corticosteroids and two showed a partial clinical response. Regardless of the HIV virological response, antiretroviral therapy did not improve MC vasculitis. Compared with patients with HCV monoinfection, coinfected patients were younger (P < 0.001), more frequently male (P = 0.03), more frequently intravenous drug users (P < 0.001), had higher HCV viraemia (P = 0.004), higher liver necroinflammation (P = 0.03), higher gammaglobulinaemia (P < 0.001) and lower cryoglobulin level (P = 0.03). The clinical manifestations of MC vasculitis did not differ significantly between the two groups. CONCLUSION: There was a beneficial effect of anti-HCV therapy for HIV/HCV-coinfected patients with MC vasculitis.

Ethnicity and association with disease manifestations and mortality in Behçet's disease.

BACKGROUND: Behçet's disease (BD) significantly increases morbidity and mortality. BD mainly affects young adults with a peculiar geographical distribution. It has been suggested that BD varies in its phenotypic expression in different ethnic groups. METHODS: We investigated potential ethnicity-related differences relative to phenotype and prognosis of BD patients in a French multiethnic country. We included 769 consecutive patients fulfilling the international criteria of classification for BD, in the 3 largest ethnic groups of our cohort [European (n = 369), North African (n = 350) and sub Saharan African (n = 50)]. Factors that affect prognosis were assessed by multivariate analysis. RESULTS: 535 (69.6%) patients were male and the median (IQR) age at diagnosis was of 30.9 (24.9-37.2) years. Sub Saharan African BD patients had a higher frequency of CNS involvement (48% vs 32.3% vs 29.5%, p = 0 .035), a higher rate of death (12% vs 6% vs 3.5%, p = 0.029) and a lower frequency of HLA B51 allele (29.4% vs 49.2% vs 55.8%, p = 0.009) compared to those from North Africa and Europe, respectively. Multivariate analysis showed that male gender (HR: 5.01, CI: 1.51-16.65), cardiovascular involvement (HR: 2.24, CI: 1.15-4.36), and sub Saharan African origin (HR 2.62 (0.98-6.97) were independently associated with mortality. The 15-year mortality rate was of 19%, 9% and 6% in sub Saharan African, North African and European BD patients, respectively (p = 0.015). CONCLUSION: We reported ethnicity-related differences with respect to phenotype of BD. Sub Saharan Africans patients exhibited a worse prognosis.

Behcet's disease in Budd-Chiari syndrome.

BACKGROUND: Behcet's disease (BD) is a well-known cause of Budd-Chiari syndrome (BCS). Data are lacking on the presentation and outcome of BCS related to BD. METHODS: We investigated the relationship between BD and BCS in 14 patients with both diseases and compared the results to 92 BCS patients without BD. RESULTS: Male gender (p = 0.003), North African origin (P = 0.007) and inferior vena cava obstruction (P < 0.0001) were more frequent in patients with BD and BCS than in those with BCS alone and the plasma C-reactive protein level was higher (p = 0.003). Two of the patients with the combined diseases underwent recanalization of the vena cava and the hepatic veins, none received transjugular intrahepatic portosystemic shunts (TIPS), one received a surgical shunt and one underwent liver transplantation. TIPS were less frequent in patients with BD and BCS than in those with BCS alone (P = 0.019). Eighty six per cent of patients with BCS and BD received corticosteroids and immunosuppressive therapy. The 5-year transplantation-free survival rate was 63% in patients with BCS alone and 91% in those without BD (P = 0.11). In our series and in the literature, a high number of patients [12 (61.5%) and 11 (64.7%) respectively] treated with anticoagulation and corticosteroids and/or immunosuppressants did not require invasive treatment. CONCLUSION: This study shows a higher frequency of IVC obstruction in patients with BCS and BD. Medical treatment with anticoagulation and immunosuppressive agents may improve the symptoms of BCS. Therefore early management with immunosuppressive and anticoagulation therapy appears to be the treatment of choice in patients with BCS and BD.

Spectrum of cardiac lesions in Behçet disease: a series of 52 patients and review of the literature.

Cardiac abnormalities in patients with Behçet disease (BD) include pericarditis, myocarditis, endocarditis with valvular regurgitation, intracardiac thrombosis, endomyocardial fibrosis, coronary arteritis with or without myocardial infarction, and aneurysms of the coronary arteries or sinus of Valsalva. Data regarding the clinical spectrum, prevalence, and outcome of cardiac lesions in BD are lacking. In this study, we report the main characteristics, treatment, and long-term outcomes of 52 patients with cardiac lesions from a cohort of 807 (6%) BD patients. Forty-five (86.5%) patients were male, with a mean (±SD) age at BD diagnosis of 29.3 ± 10.3 years.Cardiac involvement was the first feature of BD in 17 (32.7%) patients. Cardiac lesions included pericarditis (n = 20; 38.5%), endocarditis (mostly aortic insufficiency) (n = 14; 26.9%), intracardiac thrombosis (n = 10; 19.2%), myocardial infarction (n = 9; 17.3%), endomyocardial fibrosis (n = 4; 7.7%) and myocardial aneurysm (n = 1; 1.9%). Patients with cardiac involvement were more frequently male (86.5% vs. 64.9%; p < 0.01) and had more arterial (42.3% vs. 11.1%; p < 0.01) and venous lesions (59.6% vs. 35.8%; p < 0.01) compared to those without cardiac manifestations. Factors associated with complete remission of cardiac involvement were treatment regimens with oral anticoagulants, immunosuppressants, and colchicine. The 5-year survival rate was 83.6% and 95.8% (p = 0.03) in BD patients with and without cardiac involvement, respectively. After a median (Q1-Q3) follow-up of 3.0 (1.75-4.2) years, 8 patients had died, in 3 cases directly related to cardiac involvement.In conclusion, cardiac lesions affected 6% of our large cohort of BD patients. The prognosis of cardiac involvement in BD is poor and improves with oral anticoagulation, immunosuppressive therapy, and colchicine.

Long-term outcome of arterial lesions in Behçet disease: a series of 101 patients.

The vasculitis of Behçet disease (BD) is distinctive because of involvement of both arteries and veins of all sizes. The concept of vasculo-Behçet disease has been adopted for cases in which vascular manifestations are present and often dominate the clinical features. While venous manifestations are frequent and have been reported in many publications, data regarding arterial lesions in patients with BD are rare and often isolated. In this study, we report the main characteristics, treatment, and long-term outcome of 101 patients with arterial lesions among a cohort of 820 (12.3%) BD patients. Factors that affect prognosis were assessed by multivariate analysis. There were 93 (91.2%) male patients; the median (Q1-Q3) age at diagnosis of BD was 33 (27-41) years. Arterial lesions included aneurysms (47.3%), occlusions (36.5%), stenosis (13.5%), and aortitis (2.7%). Lesions mainly involved the aorta (n = 25) and femoral (n = 23) and pulmonary (n = 21) arteries. Patients with arterial lesions were more frequently male (91.2% vs. 62.4%, respectively; p = 0.017) and had higher rates of venous involvement (80.4% vs. 29.8%, respectively; p < 0.001) compared to patients without arterial manifestations. Thirty-nine (38.6%) patients achieved complete remission. In multivariate analysis, the presence of venous involvement (odds ratio [OR], 0.29; 95% confidence interval [CI], 0.08-1.11) and arterial occlusive lesions (OR, 0.13; 95% CI, 0.01-1.25) were negatively associated with complete remission. The use of immunosuppressants (OR, 3.38; 95% CI, 0.87-13.23) was associated with the occurrence of complete remission. The 20-year survival rate was significantly lower in BD patients with arterial involvement than in those without arterial lesions (73% vs. 89%, respectively; p < 0.0001). In conclusion, the long-term outcome of arterial lesions in BD is poor, especially in the case of occlusive lesions and associated venous involvement. The use of immunosuppressants improved the prognosis.

Causes and predictive factors of mortality in a cohort of patients with hepatitis C virus-related cryoglobulinemic vasculitis treated with antiviral therapy.

OBJECTIVE: Hepatitis C virus (HCV)-associated mixed cryoglobulinemia (MC) vasculitis is an autoimmune disorder with significant morbidity and mortality. Renal involvement was associated with an increased mortality, and was the most common cause of death; these data were obtained before effective antiviral treatment was available. We studied causes of death and predictive factors in patients with HCV-associated MC vasculitis treated with antivirals. METHODS: Case histories of 85 patients with HCV-associated MC vasculitis treated in a single center between 1990 and 2006 were retrospectively reviewed. Prognostic factors affecting mortality were studied by comparing 23 patients who died with 62 survivors, using the Cox model regression analysis. RESULTS: The most common cause of death was infection, accounting for 34.7%, followed by endstage liver disease in 30.4% (including 4 patients with hepatocellular carcinoma), and cardiovascular disease in 17.4% of patients. Endstage renal disease accounted for only 8.7% of deaths, as did central nervous system vasculitis and nonhepatic malignancy. Increased mortality was strongly associated with immunosuppressive treatment [hazard ratio (HR) 6.51, 95% CI 2.75-15.37], cutaneous ulcers (HR 5.37, 95% CI 1.79-16.14), and renal insufficiency (HR 3.25, 95% CI 1.37-7.72). A 2 log10 decrease in HCV viral load at month 3 after starting antiviral treatment was associated with decreased mortality (HR 0.39, 95% CI 0.16-0.95). CONCLUSION: While renal involvement is still associated with poorer prognosis, infectious processes are now the most common cause of death in HCV cryoglobulinemia vasculitis. Immunosuppressive treatment is associated with an increased risk of death, independently from disease severity. Response to antiviral treatment is associated with significantly reduced mortality risk.

Is induced abortion with misoprostol a risk factor for late abortion or preterm delivery in subsequent pregnancies?

OBJECTIVE: To examine whether a first or second trimester induced abortion with misoprostol influences the risk of late abortion or preterm delivery in subsequent pregnancies. STUDY DESIGN: Case-control study in a teaching hospital from January 2005 to June 2006. The cases had singleton pregnancies delivered at 16-36 weeks of gestation after spontaneous late abortions, preterm labor or preterm premature rupture of membrane, or induction of labor for preterm premature rupture of membrane before 37 weeks. The control group was composed of the two consecutive spontaneous singleton deliveries at >or=37 weeks of gestation after each new case (ratio 2/1). The principal outcome measure was late abortion or preterm delivery. The association between late abortion or preterm delivery and a previous induced abortion with misoprostol was first assessed with the Cochran-Mantel-Haenszel chi-square test. Conditional logistic regression models adapted for clustered data were then further used to quantify the effect size, measured by estimated odds ratios (ORs) with their 95% confidence intervals (95% CI). RESULTS: The study included 245 cases and 490 controls. There was no significant difference in mean maternal age, number of pregnancies, parity, smoking, or history of first trimester miscarriage between cases and controls. However, a history of late abortion or previous preterm delivery was significantly more frequent among cases than controls. Forty (16.3%) cases and 56 (11.5%) controls had a history of cervical ripening with misoprostol before vacuum curettage or evacuation, or of medical abortion by misoprostol alone or with mifepristone (OR 1.51, 95% CI: 0.95-2.39; p=0.08). After adjustment for maternal age and number of pregnancies with a multivariable conditional regression model, the adjusted OR was estimated at 1.33 (95% CI: 0.81-2.17; p=0.25). CONCLUSION: Despite the need for prudence, these results provide some reassurance that induced abortion with misoprostol during the first or second trimester of pregnancy is safe for subsequent pregnancies.

Quality control of surgical and interventional procedures: a review of the CUSUM.

BACKGROUND: The report of the CUSUM across surgical and interventional procedures has spawned a fair confusion in the literature. AIM: To assess the use of the CUSUM and to clarify its utilisation in the perspective of future studies. Nature of the study: Retrospective review. METHODS: A systematic literature search of Medline was carried out. From each article, data regarding the design of the study, the specialty, the performance criterion, the unit under control, the methodology and the model of the CUSUM used, the use of a graph, the use of a test and the type of test applied were retrieved. RESULTS: 31 studies were found relevant. The design was mainly retrospective for the analysis of the learning curve. The main performance criteria under control were morbidity, mortality and success of the procedure. A graph was plotted in all studies as a CUSUM plot or as cumulative sums of non-negative values. A test was used in 17 studies. Mislabelling of the plot and the test, and misuse of control limits were the most commonly reported mistakes. CONCLUSION: The CUSUM tool is not yet properly reported in the surgical literature. Therefore, reporting of the CUSUM should be clarified and standardised before its use widens.

Antiviral therapy for hepatitis C virus--associated mixed cryoglobulinemia vasculitis: a long-term followup study.

OBJECTIVE: To evaluate the long-term efficacy of anti-hepatitis C virus (HCV) therapy in patients with HCV-associated mixed cryoglobulinemia (HCV-MC) vasculitis and to assess the factors associated with clinical remission of MC. METHODS: This was a single-center study of 72 consecutive patients who received treatment with IFN alfa-2b (3 million IU 3 times a week; n = 32 patients) or PEGylated IFN alfa-2b (PEG-IFN alfa-2b) (1.5 mug/kg/week; n = 40 patients), both in combination with oral ribavirin (600-1,200 mg/day), for at least 6 months. Logistic regression was used to assess factors associated with clinical remission of MC. RESULTS: The mean +/- SD duration of followup after discontinuation of antiviral therapy was 39.7 +/- 24.4 months. Eight deaths (11.1% of patients) occurred during the study, primarily as a result of cardiovascular disease, liver disease, or infection. A complete clinical response of the MC occurred in 45 patients (62.5%), a sustained virologic response occurred in 58.3%, and cryoglobulins cleared in 45.8%. Compared with patients treated with IFN alfa-2b plus ribavirin, those receiving PEG-IFN alfa-2b plus ribavirin had a higher sustained clinical (67.5% versus 56.3%), virologic (62.5% versus 53.1%), and immunologic (57.5% versus 31.3%) response, regardless of HCV genotype and viral load. In multivariate analyses, an early virologic response (odds ratio 3.53 [95% confidence interval 1.18-10.59]) was independently associated with a complete clinical response of MC. A glomerular filtration rate

Cryoglobulinemia is associated with steatosis and fibrosis in chronic hepatitis C.

The relationship between cryoglobulin and severity of liver lesions is debated. No study has focused on the relationship between cryoglobulin, liver steatosis, and fibrosis. The aim of this study was to determine the relationship between cryoglobulins and liver lesions (necroinflammation, fibrosis, and steatosis) in patients with hepatitis C virus (HCV) infection. Four hundred and thirty-seven consecutive patients with untreated chronic hepatitis C who had been admitted for liver biopsy were included in the study. Risk factors for fibrosis and steatosis were assessed. The mean age was 50.9 +/- 13.8 years, and 49% were male. Cryoglobulin was present in 286 patients, 103 of whom had vasculitis. One hundred and eighty-six patients (43%) had steatosis greater than 10%, and 110 (25%) had advanced fibrosis (Metavir score F3-F4). On multivariate analysis, cryoglobulin increased by nearly threefold the risk of having advanced fibrosis and steatosis greater than 10%. Steatosis greater than 10% was associated with a higher body mass index (P < .001), HCV genotype 3 (P < .001), cryoglobulin (P = .002), and advanced liver fibrosis (P = .009). Advanced fibrosis (F3-F4) was associated with a higher level of gamma-glutamyltransferase (P = .04), cryoglobulin (P < .001), a high grade of necroinflammation (Metavir score A2-A3) (P < .001), and steatosis higher than 10% (P = .04). In conclusion, our study shows an independent association between cryoglobulin and steatosis as well as advanced fibrosis.
