Interestingly, the levels of anti-inflammatory IL-10 (but not IL-4) were selectively heightened, in agreement with the ability of B7-H1Ig–treated T cells to preferentially secrete IL-10,32 and increased PD-1 and IL-10 levels were found in liver transplantation patients at high risk for CMV disease.33 Moreover, PD-1–induced IL-10

may impair CD4+ T cell activation during HIV infection.34 Such an altered local inflammation was responsible for liver protection, because IL-10 neutralization restored inflammation and hepatocellular damage. In support of this notion, we have reported that IL-10 was required for liver protection in mice deficient in CXCL-10,4 and that viral IL-10 gene transfer in WT recipients prevented hepatic IR insult in association with depressed Th1 cytokine/chemokine programs.35 It is plausible MK-8669 datasheet that by virtue of selective IL-10 expression, B7-H1Ig might

raise the defensive threshold to inflammatory response in IR-exposed livers. Our results suggest that PD-1/B7-H1 interaction mediates local inflammatory cell infiltration and activation. In the first phase of IR-mediated inflammation response, activation of macrophages and Kupffer cells results in the release of TNF-α, learn more IL-1β, IL-6, CXCL-10, and CCL-2, the signature markers of liver IRI.1-5 These cytokines and chemokines also influence T cell and macrophage trafficking patterns, as evidenced by increased numbers of infiltrating CD3+ cells and F4/80+ cells. However, stimulating PD-1 signals blunted the number of macrophages sequestered in the liver and their inflammation/chemotactic expression programs. In the second phase of IRI, activated neutrophils dominate local damage cascade.1, 2 We observed a marked increase in Ly-6G+ neutrophil

infiltration and myeloperoxidase activity in control 上海皓元 livers compared with sham controls. Unlike the control group, livers in B7-H1Ig–treated mice were characterized by decreased neutrophil sequestration, along with diminished CXCL-1 and CXCL-5, the key chemoattractants facilitating neutrophil recruitment in hepatic IR inflammation. As T helper 1–derived IFN-γ acts directly on neutrophils to enhance their sequestration in the liver, B7-H1 cross-linking can regulate neutrophil function through cytokine/chemokine networks. One of the principal mechanisms by which PD-1/B7-H1 ligation affects host alloimmunity is through modulation of T cell apoptosis.12 B7-H1 but not PD-1 blockade inhibited apoptosis of alloantigen-specific T cells in transplant recipients,20 and B7-H1 was identified as a key protein controlling deletion of hepatic CD8+ T cells.

For patient with gastroesofageal, performing endoscopy can detect

For patient with gastroesofageal, performing endoscopy can detect underlying esofagitis, barret’s esofagus and malignancy. The aim of this study was to establish the etiology of gastroesofageal refluks disease on upper endoscopic investigation. Methods: We collected upper endoscopy procedures results among gastroesofageal reluks patients at endoscopic centre Adam Malik Hospital January 2011 to July 2013. A detailed personal interview was conducted to establish clinical gastroesofageal symptoms and medication. We

also determined sociodemographic profile of each patient. Results: There are 140 gastroesofageal patients, 60 (42,8%) were male and 80 (57,1%) were female. The main endoscopic findings were normal 103 (73,5%), esofagitis 25 (17,8%), barret’s esofagus 10 (7.1%), esofagus carcinoma 12 (8.5%). Conclusion: Normal mucosa is a common diagnostic patients

with gastroesofageal refluks.

Isolated amyloidosis in the stomach is even more MCE rare. Methods: We report two cases of gastric amyloidosis. Results: Case1:A seventies woman was admitted with epigastric pain. An upper gastrointestinal endoscopy revealed a tumor at the inferior part of gastric corpus which was elevated lesion with redness. The gastric cancer it indicates the form like a submucosal tumor to be was suspected. Histological examination of biopsy specimens from this lesion showed deposition of amorphous,

homogeneous and acidophilic material in the gastric mucosa. This was consistent with a diagnosis of gastric amyloidosis.Immunohistochemistry for ATTR (amyloidgenic transthyretin) was strongly positive. There is no gene mutation of TTR and it carried out the final diagnosis to the ATTR of wild type TTR (senile systemic amyloidosis: SSA). It was a rare case of localized gastric amyloidosis of ATTR. SSA also easy to merge the digestive tract amyloidosis. The classification of amyloidosis should be performed by immunity staining including TTR. Case2:A sixties man was admitted with diarrhea and anorexia. An upper gastrointestinal endoscopy revealed small curvature at the part of gastric upper corpus which was elevated lesion with ulcer. Histological examination of biopsy specimens from this lesion showed deposition of amorphous, homogeneous and acidophilic material in the gastric mucosa. Immunohistochemistry for AL lambda was strongly positive.

Thus, a higher PPV suggests more accuracy of a test in identifyin

Thus, a higher PPV suggests more accuracy of a test in identifying patients with good prognosis; a higher NPV suggests more accuracy of a test in identifying patients with poor prognosis; and a lower NLR suggests more accuracy of a test in identifying patients with

poor prognosis. The performance of biochemical response after 3, 6, and 12 months of UDCA therapy for prediction of long-term outcome was assessed (Table 4). We found that biochemical responses at the sixth month may identify patients with good or poor prognosis with no less accuracy than evaluation at 1 year. The former showed higher or the same PPV and NPV and lower NLR than the latter by all definitions tested. In contrast, biochemical responses at the third month demonstrated higher PPV, lower NPV, and increased NLR by all definitions compared with biochemical responses at 1 year. Midostaurin chemical structure It can be inferred that biochemical responses at the third month were superior in identifying patients with good prognosis, yet were less potent in selecting high-risk patients for therapeutic trials. Our findings are in accordance with and provide more direct evidence to the statement that

therapeutic trials should target patients with incomplete biochemical response after 3 to 6 months of UDCA treatment.11 Our study was limited by small sample size and relatively CCI-779 short duration of follow-up. Another limitation is that a considerable proportion of patients did not strictly follow the regular 3-month examination interval, making biochemical data available for 128 (68.4%) patients for the third month after UDCA treatment, 145 (77.5%) patients for the sixth month, and 157 (84.0%) patients for 1 year. MCE To make full use of the available data, we used all data for the statistical analyses. To avoid bias, we compared the baseline characteristics of patients with or without recorded biochemical data. They did not differ statistically in age, sex, baseline biochemical data, and long-term outcomes

(data not shown). Thus, the influence of missing data would mostly likely not effect the results. The strict criteria for selecting patients at entry, the careful follow-up of patients, and the prospective nature of the collected data can partly compensate for these limitations. The evolution of laboratory liver parameters within the first year of UDCA therapy, the compatibility of biochemical response at 3, 6, and 12 months in discriminating patients with good or poor outcome, and similar prognostic impact of biochemical responses at 6 and 12 months together contributed to our conclusion that an early biochemical response at 6 months would as efficiently identify patients at risk of poor outcome as evaluation at 1 year.

Methods compared included a modified Nijmegen-Bethesda assay (MNB

Methods compared included a modified Nijmegen-Bethesda assay (MNBA), with a heating step to remove FVIII added to the standard NA [14]; an identical assay using chromogenic measurement of FVIII, a chromogenic Nijmegen-Bethesda

assay (CBA) [15]; and a novel FLI measuring binding of antibodies to recombinant FVIII bound to polystyrene microspheres [15]. CBA was negative in 99.7% of 883 MNBA-negative specimens and positive in 100% of 42 specimens with inhibitor activity ≥2 NBU (Nijmegen-Bethesda units) in the MNBA (r = 0.98). Among 1005 specimens, 40 (4%) were MNBA-positive and CBA-negative, all with 0.5–1.9 NBU; 58% of the 40 were FLI-negative, 13% had evidence of lupus anticoagulant, and 36% lacked time-dependent inhibition, suggesting atypical FVIII or non-FVIII inhibitors. Antibodies binding to FVIII were detected by FLI in 98% of CBA-positive specimens but only 82% of MNBA-positive specimens (P = 0.004). Of positive inhibitors <2 NBU, selleck compound 26% were negative by both CBA and FLI, including 50% of those with 0.5–0.9

NBU. Some specimens could be documented to be false-positives, probably due to the assay variability, as described above. Low-titre inhibitors, however, were sometimes positive by both confirmatory tests, suggesting that they can represent true positives. These data illustrate SB431542 datasheet heterogeneity in low-titre inhibitors and suggest that caution be used in their interpretation. FLI also detected antibodies in 21% of MNBA-negative specimens. This frequency of non-inhibitory antibodies is similar to those seen with ELISA and immunoprecipitation assays and may be due to increased sensitivity over the standard NA. Dilution studies show that the FLI detects antibody titres down to 0.03 NBU. Alternatively, these antibodies may have qualitative differences causing them to fail to react in functional assays. Their clinical significance is not clear. This study concluded that low-titre 上海皓元 inhibitors detected in clot-based assays should be repeated for confirmation and evaluated with tests that more directly demonstrate reactivity with FVIII. Many laboratories

have the capability to perform chromogenic assays on automated analysers and could implement the CBA for the few specimens requiring validation. The US inhibitor surveillance programme has recently been initiated, with centralized testing conducted at the CDC using the MNBA to allow testing during replacement therapy. Specimens with 0.5–1.9 NBU will be checked with the CBA and FLI to assess their reactivity with FVIII. For any new inhibitor, a second specimen will be requested for confirmation; data will then be collected on the patient’s history, including product exposures, for the 4 months prior to inhibitor detection to evaluate risk factors. Current broad performance of factor inhibitor assays by laboratories is plagued by high variability, and significant risk of both false positives and negatives.

Hence, further investigation is needed to better delineate the ro

Hence, further investigation is needed to better delineate the role of DWI in characterizing FLL. Intravenous MR contrast agents can be divided into extracellular (ECA) and hepatocyte-specific agents (HSA). ECA equilibrate with the extracellular fluid space after intravenous injection and are excreted by glomerular filtration, similar to CT agents.

This permits multiphase dynamic postcontrast imaging during late arterial, portal venous, BMN 673 manufacturer and equilibrium phases, allowing assessment of enhancement kinetics, a reflection of both vascularity and permeability. HSA have dual elimination, with a portion of the dose distributed extracellularly and eliminated by the kidneys; the remainder is taken up by hepatocytes and excreted into the bile. The two HSAs available in the U.S. are Eovist (gadoxetate disodium, Bayer HealthCare Pharmaceuticals, Cabozantinib cost marketed as Primovist outside the U.S.) and Multihance (gadobenate dimeglumine, Bracco). To date, no large studies compare diagnostic accuracy of the two HSAs for FLL characterization. With Eovist, 50% of the dose is taken up by hepatocytes and eliminated by way of biliary excretion, compared to 3%-5% with MultiHance. This results in greater hepatobiliary phase parenchymal enhancement with Eovist. Hepatobiliary phase images are acquired

20-40 minutes after Eovist injection, compared to 1-2 hours after Multihance injection. HSAs possess some properties of ECA, yielding dynamic postcontrast imaging with the added benefit of hepatobiliary phase imaging. The Food and Drug Administration (FDA)-approved dose of Eovist is 0.025 mmol/kg, which is one-fourth that of other approved agents.

Although Eovist has greater T1 relaxivity, this reduced dose may lead to less robust arterial enhancement, prompting some radiologists to double the dose or acquire multiple arterial phases.24, 25 Additionally, hepatocyte uptake may begin as early as the portal venous phase, potentially confounding evaluation of enhancement kinetics. Given these issues, in our practice Eovist is the contrast of choice when evaluating suspected FNH and staging metastatic disease. However, for routine problem-solving MRI and in patients with suspected HCC, Eovist is reserved for special cases. Hepatic hemangiomas are the most common benign FLL, with an incidence of 2%-20%.1-5 Classic MCE公司 MRI features include round or lobular margins, marked T2 hyperintensity (referred to as light-bulb bright), and characteristic enhancement pattern.26-30 Three distinct patterns of enhancement have been described on ECA-enhanced MRI, with reported specificities of 100% and diagnostic accuracies of 95%.31 Smaller lesions (<1.5 cm) may demonstrate uniform arterial enhancement, referred to as flash-filling. Larger, cavernous hemangiomas demonstrate either nodular peripheral interrupted enhancement coalescing centripetally to uniform enhancement (Fig.

1A). HNF-4α/PGC-1α promoted both the wild-type and ΔA reporter expression levels (Fig. 1C). On the other hand, this HNF-4α/PGC-1α–driven expression was lost by deleting or mutating site B (Fig. 1C). Similar results were obtained in human hepatocarcinoma HepG2 cells (Supporting Information Fig. 1). We next investigated if HNF-4α can bind to site B response element. We prepared nuclear Selleckchem Panobinostat extracts from cells infected with

a control adenovirus (Adeno-ΔE1E3) or an adenovirus encoding HNF-4α (Adeno-HNF-4α) to perform electrophoresis mobility shift assays (EMSAs). Using a biotin-labeled oligonucleotide based on site B sequence as a probe, we found that Adeno-ΔE1E3 nuclear extract bound to this probe, generating several nonspecific bands that were not competed by a nonlabeled site

B probe (Fig. 1D). In contrast, Adeno-HNF-4α nuclear extract specifically bound to the probe Selumetinib order generating a specific band that was competed by a wild-type but not by a mutant site B nonlabeled probe (Fig. 1D). In addition, this specific band was super-shifted by an antibody against HNF-4α (Fig. 1D), indicating that HNF-4α binds to site B probe specifically in vitro. We then used a chromatin immunoprecipitation (ChIP) analysis to confirm that liver HNF-4α binds to site B in vivo. An antibody against HNF-4α immunoprecipitated a chromatin fragment containing site B; whereas, a nonspecific antibody (immunoglobulin G [IgG]) or mock control did not (Fig. 1E). On the other hand, none of the antibodies or the mock control immunoprecipitated a chromatin fragment spanning site A (Fig. 1E). As a positive control, we found that a chromatin fragment spanning the published HNF-4α binding site on G6P was specifically medchemexpress pulled down by the HNF-4α antibody (Fig. 1E). Collectively, our analysis indicated

that HNF-4α and PGC-1α control the expression of PLA2GXIIB through a bona fide HNF-4α response element located at site B. To further address if modulating HNF-4α activity alters PLA2GXIIB expression, we first used the HNF-4α agonistic modulators propionate and butyrate to enhance HNF-4α activity.2, 10 HeLa cells were transfected with either the wild-type or site B mutant reporter plasmid together with HNF-4α and PGC-1α expression vectors. We found that the HNF-4α/PGC-1α–driven pGL3-mPLA2GXIIB reporter expression was further enhanced by both propionate and butyrate (Fig. 2A); whereas, these treatments had no effect on the site B mutant reporter (Fig. 2A). In addition, we found that the messenger RNA (mRNA) expression level of PLA2GXIIB was induced by propionate and butyrate in HepG2 cells, which express HNF-4α endogenously (Fig. 2B).

lab BYL719 supplier profile at DILI onset (54% vs 20%, p < 0.01). In addition, the persisters had significantly higher serum ALK levels at presentation (394 vs 219 IU/ml, p <.01) and peak ALK levels (599 vs 246 IU/ml, p< .01) during follow-up. However, the implicated drugs and disease severity at DILI onset were similar in both groups. On multivariate analysis, heart disease and higher ALK levels at DILI onset were independent predictors of persistent DILI (c-stat =0.76 (0.67, 0.86)). In the 17 subjects with liver biopsies obtained at a median of 387 days after DILI onset (range: 224-698 days), 9 had chronic cholestasis, 3 had steatohepatitis, and 3 had chronic hepatitis. Of 12 patients with paired biopsies, 8 had progressive fibrosis and 1 improved. Although age and gender adjusted SF-36 scores improved in both groups over time, the persistent DILI patients had

significantly lower physical summary (PCS) and physical functioning BAY 80-6946 mouse subscale scores at baseline, mon 6, and mon 12 compared to the 25 resolvers (p< 0.01). CONCLUSIONS: The majority of subjects with active liver disease at 6 months after DILI onset continued to have ongoing liver injury at month 12. With these results, we propose that persistent liver injury be defined at 12 months after DILI onset and that subjects with ongoing injury at 6 months be carefully monitored for clinical and histological evidence of liver disease progression.

Davern, Jose Serrano Prostaglandins (PGs) are lipid mediators implicated in various biological and pathobiological functions. The synthesis of PGs in human cells is controlled by the cyclooxygenases (COXs, including COX-1 and COX-2) that catalyze the formation of endoperoxide prostaglandin H2 (PGH2) from membrane arachidonic acid as well as by the specific PG synthases that catalyze the formation of individual PGs from PGH2. While there is compelling evidence for the involvement of PGE2 in hepatic inflammation and carcinogenesis, the effort to target PGE2 for therapy has been hindered by the potential side effect associated with COX inhibitors (mainly due to altered prostacyclin and thromboxanes).

F4/80+ KCs expanded from a baseline of 20%-25% in control liver t

F4/80+ KCs expanded from a baseline of 20%-25% in control liver to 40%-50% in NASH. Gr1+ neutrophils and inflammatory monocytes Selleck Enzalutamide expanded from ∼10% in controls to ∼25% in NASH, whereas both natural killer T (NKT) cells and B cells decreased as a fraction of total NPC (Fig. 1C). The fraction of hepatic CD3+ T cells remained fairly stable in NASH; however, we observed marked upward skewing of the CD8+/CD4+ ratio (Fig. 1D). Moreover, CD11c+MHCII+ DCs expanded from a baseline of ∼5% of liver leukocytes in control

liver to 15%-18% in NASH (Fig. 1C,E). Expansion of CD11c+MHCII+ DCs began within days of initiating an MCD diet, plateaued by 2 weeks, and remained stably elevated for the duration of disease (Fig. 1F). By contrast, there was no change in splenocyte composition, splenomegaly, or evident expansion Selleck Autophagy Compound Library of splenic DCs in NASH, implying that the effects of NASH on DCs are specific to the liver (Supporting Fig. 1B,C). Besides expanding in number, hepatic DCs underwent phenotypic maturation in NASH. MHCII and CD40, both essential for antigen presentation, were up-regulated on NASH DCs, as was the expression of costimulatory molecules CD54, CD80, and CD86 (Fig. 1E and Supporting Fig. 2A). CD1d, necessary for DC induction of

NKT cells, was expressed at lower levels on NASH DCs (Supporting Fig. 2A), which correlates with the observed diminution in the fraction of NKT cells in NASH liver (Fig. 1C). The increased maturation of NASH DCs, compared to controls, was also evident after 24 hours of in vitro culture (Supporting Fig. 2B). Besides phenotypic maturation, the fractional subsets of liver DCs were markedly altered in NASH. The B220+ plasmacytoid DC population was decreased in NASH. Conversely, the CD11b+CD8− myeloid DC population expanded by approximately 20%-30%, whereas the fraction of CD11b−CD8a+ lymphoid DC decreased proportionately (Supporting Fig. 2C). In contrast to liver DCs, spleen DC phenotype was unaltered in NASH (Supporting Fig. 2D). Because secreted cytokines

are critical in NASH pathogenesis and DCs can regulate 上海皓元医药股份有限公司 inflammation through production of soluble inflammatory mediators, we tested cytokine production from DCs isolated from NASH liver. NASH DC produced increased levels of TNF-α, IL-6, monocyte chemoattractant protein 1 (MCP-1), and IL-10, compared to normal liver DCs (Fig. 2A,B). NASH DCs also exhibited increased cytokine responses to TLR9 ligation (Fig. 2C). Consistent with these observations, hepatic DCs increased their expression of TLRs in NASH (Fig. 2D). Liver DCs have the capacity to induce either immunogenic responses or tolerance, depending on physiologic circumstance.[15] NASH liver DCs exhibited an increased ability to induce allogeneic T-cell stimulation (Supporting Fig. 3A). Similarly, liver DC capacity to induce antigen-restricted CD4+ T-cell proliferation (Supporting Fig. 3B), as well as CD4+ T-cell production of T-helper cell (Th)1, Th2, and Th17 cytokines, was increased in NASH (Supporting Fig. 3C).

[26] C/EBPα knockout mice demonstrate decreased hepcidin expressi

[26] C/EBPα knockout mice demonstrate decreased hepcidin expression and iron overload.[26] The pathways described earlier activate hepcidin transcription, but only one pathway has been identified that represses hepcidin expression. The transmembrane serine protease (TMPRSS6) is part of the pathway that suppresses Selleck Rucaparib hepcidin expression as revealed in TMPRSS6 mutant mice.[27] Based on the assumption that one-third of iron stores are normally in the liver, this would translate to a normal median

hepatic iron content of 0.27 g for men and 0.13 g for women.[28] Extensive studies reported median hepatic iron concentrations of 396 (range 0–2105) and 458 (range 114–2190) μg/g dry weight liver tissue in patients with chronic hepatitis C.[29, 30] These results suggest that hepatic iron content in patients with chronic hepatitis C is approximately 0.50∼0.69 g, equivalent to two to five times the normal hepatic iron content if the liver weight is estimated to be 1500 g. In contrast, a hepatic iron index (μmol Fe/g liver tissue/patients age) of 1.9 or more has been

reported to be typical of patients with hereditary hemochromatosis.[31] If the hepatic iron index of a patient aged 60 with hereditary hemochromatosis is 1.9, the hepatic iron concentration of this patient is assumed to be 6384 μg/g liver tissue. Thus, we should understand that hepatic iron content is much less in chronic hepatitis C than in hereditary Ruxolitinib solubility dmso hemochromatosis, even though it is recognized to be one of liver diseases that show hepatic iron accumulation. There also remains uncertainty

MCE公司 as to whether iron predominantly accumulates in hepatocytes or the reticuloendothelial system, mainly Kupffer cells, in patients with chronic hepatitis C. Some clinical studies showed that iron was mainly localized in the reticuloendothelial system,[32, 33] whereas others reported its localization in hepatocytes.[34] Interestingly, Fiel et al. documented that even ribavirin-associated hemolysis deposited iron preferentially in hepatocytes in patients with chronic hepatitis C.[35] Hepatocytic iron accumulation may indicate potential DNA damage and genetic instability in association with HCV-induced oxidative stress, whereas iron deposition in Kupffer cells may contribute to cytokine release leading to inflammation or fibrosis. However, further investigations are needed to clarify this issue. HFE is a major histocompatibility class I-like (MHC) molecule that, unlike other known classical and non-classical MHC proteins, has a regulatory role in the functions of iron metabolism in cells and the body. A homozygous mutation in the HFE protein in humans that changes cysteine at position 282 to tyrosine is responsible for iron overload and organ damage resulting in hemochromatosis.[36] The role of HFE mutations in chronic hepatitis C has been well reviewed.

Statistical analyses were performed using SPSS (Chicago, IL) Sen

Statistical analyses were performed using SPSS (Chicago, IL). Sensitivity, specificity, positive predictive value (PPV), and negative predictive FG-4592 manufacturer value (NPV) were also calculated to determine the reliability of predictors of the response to therapy. Sustained virological response was achieved by 44 of 72 (61.1%) patients.

In all, 64 of 72 (88.9%) patients were considered end-of-treatment response. According to treatment regimen, sustained virological response were achieved by 45.0% (9 of 20 patients) and 67.3% (35 of 52 patients), in the T12PR12 group and the T12PR24 group, respectively. Of eight patients who could not achieve end-of-treatment response, six (75.0%) patients resulted in reelevation of viral loads regardless of HCV-RNA temporary negative, and the other two patients (25.0%) did not achieve HCV-RNA negative during treatment. Especially in the T12PR24 group, according to the past history of treatment, sustained

virological response were achieved by 76.4% (13 of 17 patients), 86.4% (19 of 22 patients), and 23.1% (3 of 13 patients), in treatment-naive, relapsers to previous treatment, and nonresponders to previous treatment, respectively. According to the substitution of core aa 70, a significantly higher proportion of patients with Arg70 substitutions (74.4%) showed sustained virological see more response than that of patients who showed Gln70(His70) (41.4%) (Fig.

1, P = 0.007). In contrast, according to the substitution of core aa 91, the sustained virological response rate was not significantly different between Leu91 (65.0%) and Met91 (56.3%) (Fig. 1). Likewise, according to the numbers of aa substitutions in ISDR, the sustained virological response rate was not significantly different between wildtype (56.3%) and nonwildtype (66.7%) (Fig. 1). Thus, sustained 上海皓元 virological response was influenced by the substitution of core aa 70. According to the genetic variation in rs8099917, sustained virological response was achieved by 83.8% (31 of 37 patients), 29.6% (8 of 27 patients), and 0% (0 of 2 patients) in patients with genotype TT, TG, and GG, respectively. Thus, a significantly higher proportion of patients with genotype TT (83.8%) showed sustained virological response than that of patients who showed genotype non-TT (27.6%) (Fig. 2, P < 0.001) (Table 2). According to the genetic variation in rs12979860, sustained virological response was achieved by 83.8% (31 of 37 patients), 34.5% (10 of 29 patients), and 0% (0 of 2 patients), in patients with genotype CC, CT, and TT, respectively. Thus, a significantly higher proportion of patients with genotype CC (83.
