166 This observation led to the proposal that HBOT might be beneficial in the treatment of vascular-related headaches refractory to traditional pharmacological therapy. HBOT may be effective via its effect on several aspects of migraine pathogenesis, via activity ERK inhibitor as a serotonergic agonist and an immunomodulator of response to substance P.167,168 In addition, the role of HBOT

in moderating inflammatory pathways may be useful in targeting migraine, both as acute and preventative treatment.169,170 Practical limitations of HBOT include the requirement of a compression chamber and potential adverse effects such as pressure-related damage to the ears, sinuses, and lungs, temporary worsening of myopia, claustrophobia and oxygen poisoning.171 A recent Cochrane Review171 assessing the safety and effectiveness of HBOT and normobaric oxygen therapy (NBOT) in the Selleck Peptide 17 treatment and prevention of migraine and cluster headaches found only 9 small randomized trials, with a total of 201 participants. Five trials compared HBOT with sham therapy for acute migraine treatment, 2 compared HBOT to sham therapy for cluster headache, and 2 assessed NBOT for cluster headache. Although there was some evidence suggesting that HBOT was effective in acute migraine treatment as compared to sham therapy, there was no evidence that it was useful in preventing migraine or reducing the incidence of nausea, vomiting, or the need for rescue medication.

The use of NBOT in the termination of cluster headaches was supported only by weak evidence from 2 small randomized trials, but given the safety and ease of treatment, the use of NBOT will likely continue. There is insufficient evidence from randomized trials to establish whether HBOT is

effective in the acute treatment of cluster headache. Lastly, there was no evidence to suggest that either NBOT or HBOT were effective in the prevention of either migraine or cluster headaches. There is a growing role for CAM treatment in the multidisciplinary management of headache disorders. In addition to their potential in decreasing headache frequency and intensity, these modalities also serve to provide the patient with a greater sense of self-efficacy. However, despite the supporting evidence discussed selleck in this review, there is still much to be learned about these therapeutic options and how they influence the course and outcome of headache disorders. Future research should focus on extending the current evidence base using updated standards and more rigorous methodology, and identifying which patients would be responsive to such approaches. “
“(Headache 2010;50:314-322) Arachnoid cysts represent a common, innocent, finding in routine neuroimaging of headache patients. We present the first report of symptomatic migraine with aura caused by the spontaneous rupture of a middle fossa arachnoid cyst into the subdural space. Brain imaging enabled an accurate diagnosis and, subsequently, adequate surgical management.

The homo-deletion of TAT gene was further confirmed by southern blot analysis (Fig. 1C) using a full-length TAT probe. Compared with the TAT PD-0332991 supplier band detected in paired nontumor liver tissue, a very weak band was detected in HCC tissues in H12 and H36. To identify the homo-deleted region, five sets of primers

were designed to amplify TAT, GST3 (≈30 kb from the 3′ of TAT) and K2F gene (≈90 kb from the 3′ of TAT, Fig. 1D). PCR results indicated that the homo-deletion region in H12 was from exon 4 to 11 of TAT, whereas the deleted region in H36 was from exon 4 of TAT to GST3 (Fig. 1D). Semiquantitative reverse-transcription PCR (RT-PCR) was used to investigate the expression status of TAT in 50 pairs of primary HCCs. Compared with their paired nontumor liver tissues, down-regulation of TAT was detected in 28/50 (56%) of HCCs (Fig. 2A; Table 1). The results were further confirmed by qPCR (Fig. 2B) and northern blot analysis. Down-regulation of TAT was detected in all seven tested cases including absent expression of TAT in six cases (Fig. 2C). Down-regulation of TAT was also detected in 3/6 (50%) of HCC cell lines compared with that in MIHA, an immortalized liver cell line (Fig. 2D).

TAT protein expression status was further studied in 148 primary HCCs by IHC using a tissue microarray. Compared with their paired nontumor Alisertib liver tissues, down-regulation of TAT protein was observed in 77/138 (55.8%) of informative HCCs (Fig. 2E). To determine whether the down-regulation of TAT was associated with aberrant methylation, the HCC cell line QGY-7703 was treated with 5-Aza, a DNA methyltransferase inhibitor. After

5-Aza treatment, TAT expression levels were dramatically increased, indicating that methylation of the TAT was associated with the down-regulation of TAT in HCC (Fig. 3A). The upstream sequence selleck chemical of TAT gene (−1-6761) was analyzed using the CpG-island finder and plotting tool (http://www.ebi.ac.uk/Tools/sequence.html) and one CpG-island (CGI) at −4888-5396 (a total of 23 CpG sites in a 509-basepair region) was found (Fig. 3B). To determine whether epigenetic silencing of TAT in HCC cells is regulated by this 5′-CGI, MSP using methylation- or unmethylation-specific primers was performed in HCC cell lines and primary HCCs to investigate the methylation status of TAT. In three HCC cell lines (QGY-7703, BEL7402, and Hep3B) with absent expression of TAT, only the methylated allele of TAT was detected (Fig. 3C). Both methylated and unmethylated alleles were found in 7701 cells with weak TAT expression. In contrast, no methylated allele was observed in one immortalized liver cell line (MIHA) and two HCC cell lines (HepG2 and PLC8024) with TAT expression (Fig. 3C). These data indicated that promoter methylation might be required for the tissue-restricted TAT expression. We next investigated the methylation frequency of TAT in 50 primary HCC tumors and their paired nontumorous tissues by MSP.

In all instances, known positive and known negative controls were used throughout, and all assays were performed in triplicate. Fresh liver specimens from 12 patients with PBC, 15 patients with hepatitis C infection, and seven patients with discrete intrahepatic tumors (unaffected non–tumor-bearing liver) were fixed in 10% neutral-buffer formalin and snap-frozen in OCT compound (Miles, Inc., Elkhart, IN). Deparaffinized and rehydrated sections, and frozen sections, were used for immunostaining for cell surface markers, CD68 (expressed particularly on monocytes/macrophages) and CD154 (expressed

particularly on activated T cells). Endogenous peroxidase was blocked in normal goat serum diluted 1:10 (Vector Laboratories, see more Burlingame,

CA) for 20 minutes; CD68 and CD154 were diluted 1:100 (Dako), and immunostaining was performed on coded sections and interpreted by a blinded qualified liver pathologist. All experiments were performed in triplicate, and data points shown are means of results of these triplicates. Comparisons between the points for data items are expressed as the mean Palbociclib mouse ± standard deviation, and the significance of differences was determined using the Student t test. All analyses were two-tailed, and P < 0.05 was considered significant. Statistical analyses were performed using Intercooled Stata 8.0 (Stata Corp, selleck chemicals College Station, TX). We assessed the production of CX3CL1 by isolated populations of liver cells in PBC and control patients after stimulation by different TLR ligands. With ECs, production was induced by LTA, poly(I:C), LPS, and flagellin, but not by CL-097, ODN2216, or ODN2006. Levels of CX3CL1 in PBC versus non-PBC disease controls were as follows: LTA, 1.7 ± 0.9 versus 1.6 ± 0.9 ng/mL (P value not

significant); poly(I:C), 7.8 ± 1.0 versus 7.9 ± 1.7 ng/mL (P value not significant); LPS, 4.9 ± 0.9 versus 5.1 ± 1.0 ng/mL (P value not significant); and flagellin, 0.5 ± 0.2 versus 0.6 ± 0.2 ng/mL (Fig. 1A). Levels of CX3CL1 in normal liver controls were as follows: LTA, 1.8 ± 0.6 ng/mL; poly(I:C), 8.0 ± 1.5 ng/mL; LPS, 4.9 ± 1.8 ng/mL; and flagellin, 0.6 ± 0.4 ng/mL (Fig. 1A); these differences were not significant. Although activated LSECs mediate CX3CL1 shedding and release of chemotactic peptides,20 neither LSECs nor BECs produced CX3CL1 after stimulation with any of the TLR ligands used (data not shown) in PBC, non-PBC disease controls, and normal liver controls. Because previous reports demonstrated that BECs produce chemokines in coculture with autologous LMCs,1 and because TNF-α and IFN-γ enhance CX3CL1 production from mucosal ECs,21 we used an LMC and BEC coculture system with or without the addition of TNF-α or IFN-γ. No production of CX3CL1 by BECs with LMCs was induced with any TLR ligands (data not shown).

. More than a dozen other miscellaneous agents have been investigated in small, Chk inhibitor proof-of-concept studies and their detailed evaluation is beyond the scope of this guideline. Recommendations 23. UDCA is not recommended for the treatment of NAFLD or NASH. (Strength – 1, Quality – B) 24. It is premature to recommend omega-3 fatty acids for the specific treatment of NAFLD or NASH but they may be considered as the first

line agents to treat hypertriglyceridemia in patients with NAFLD. (Strength – 1, Quality – B) As the majority of patients undergoing bariatric surgery have associated fatty liver disease, there has been an interest in foregut bariatric surgery as a potential treatment option for NASH. There are no RCTs that evaluated any type of foregut bariatric surgical procedure to specifically treat NAFLD or NASH. However, there are several retrospective and prospective cohort studies that compared liver histology in the severely obese individuals before and after bariatric surgery. Unfortunately, in the majority of these studies, post-bypass liver biopsies

were performed at varying intervals and only in selected patients undergoing surgical procedures such as hernia repair or adhesiolysis. One exception is the study by Mathurin et al.,143 that prospectively correlated clinical and metabolic data with liver histology Kinase Inhibitor Library clinical trial before and 1 and 5 years after bariatric surgery in 381 adult patients with severe obesity. Gastric band, bilio-intestinal bypass, and gastric bypass were done in 56%, 23%, and 21%, respectively. Compared to baseline, there was a significant improvement in

the prevalence and severity of steatosis and ballooning at 1 and 5 years following bariatric surgery. In patients with probable or definite NASH at baseline check details (n=99), there was a significant improvement in steatosis, ballooning, and NAS and resolution of probable or definite NASH at 1 and 5 years following bariatric surgery. Most histological benefits were evident at 1 year with no differences in liver histology between 1 and 5 years following bariatric surgery. Intriguingly, a minor but statistically significant increase in mean fibrosis score was noted at 5 years after the bariatric surgery (from 0.27± 0.55 at baseline to 0.36 ± 0.59, P=0.001). Despite this increase, at 5 years 96% of patients exhibited fibrosis score ≤ F1 and 0.5% had F3, indicating there is no clinically significant worsening in fibrosis that can be attributed directly to the procedure. In the important subgroup of patients with probable or definite NASH at baseline, there was no worsening of fibrosis at 1 and 5 years, compared to baseline liver biopsy. As no patient in the study had F3 or F4 at baseline, the effect of bariatric surgery in those with advanced fibrosis and cirrhosis could not be evaluated. Two meta-analyses144, 145 evaluated the effect of bariatric surgery on the liver histology in patients with NAFLD.

Hal, as he was called by friends and colleagues, attracted trainees from other countries, among them Guadalupe Garcia-Tsao from Mexico, Gregory Taggard from Australia, Simon Bar-Meir from Israel, and Jean-Pierre Vinel and Thierry Poynard from France. One of his proudest professional accomplishments was “The Histopathology of the Liver” by Klatskin and Conn, published in 1995, 9

years after Gerald Klatksin died and Selleckchem Tigecycline 3 years after Conn had retired. The book was a benchmark reference for the histopathological diagnosis of chronic liver diseases. It was his last big project, as he had contracted a disease unknown to him (normal pressure hydrocephalus; NPH). His NPH was erroneously diagnosed for 10 years as Parkinson’s disease and greatly affected his ability to walk or think clearly until the correct diagnosis was made. A miraculous remission followed brain surgery, and at age 78, he became an expert about, and a spokesperson for, NPH awareness. In the decade that followed, he wrote a dozen meaningful articles about NPH,

its prevalence, and heredity and appeared on national radio and TV programs. In addition, he made himself available to advise patients and the families of friends as a good Samaritan about the PLX4032 in vitro diagnosis and treatment of NPH. He became a member of American Airlines’ 2 million mile club in 1990, which were primarily accumulated from giving lectures. He was an excellent lecturer, the skills for which he credits his brother, Jerome, who spoke at many of his classes and later discovered Conn’s Syndrome I (primary aldosteronism). Conn, a workaholic who spent countless hours researching articles, is the namesake for the Conn Center, a classroom at Yale’s Cushing/Whitney Medical Library. He was also an avid squash player who contributed the “Conn Family Court” to Yale’s Brady Squash click here Center. Conn was also well known for his innovative holiday cards incorporating the family name. He is survived by his wife of 60 years, Marilyn Barr Conn, of Pompano

Beach, Florida, three children, Chrysanne (Richard) Vogt of Northford, Connecticut, Steven (Emily Resnik Conn) of Woodbridge, and Dorianne Conn (Jeff Balch) of Evanston, Illinois, and six grandchildren. The authors gratefully acknowledge Steven Conn for his many personal insights. “
“Primary intestinal lymphangiectasia (PIL) is a protein-losing enteropathy characterized by tortuous and dilated lymph channels of the small bowel. The main symptoms are bilateral lower limb edema, serosal effusions, and vitamin D malabsorption resulting in osteoporosis. We report here a case of long-lasting misdiagnosed PIL with a peculiar liver picture, characterized by a very high stiffness value at transient elastography, which decreased with clinical improvement. The complex interplay between lymphatic and hepatic circulatory system is discussed.

7%), whereas only 3 HCCs contained definite CD133+ cells (20%) (Table 2). CD90+ cells were detected at variable frequencies in all 15 HCCs

analyzed. To explore the status of these CSC marker-positive cells in HCC in a large cohort, we utilized oligo-DNA microarray data from 238 HCC cases (GEO accession no.: GSE5975) to evaluate the expression of EPCAM (encoding EpCAM and CD326), THY1 (encoding CD90), and PROM1 (encoding CD133) in whole HCC tissues and nontumor (NT) tissues. Because previous studies demonstrated that CD133+ and CD90+ click here cells were detected at low frequency (∼13.6% by CD133 staining and ∼6.2% by CD90 staining) in HCC, but were almost nonexistent in NT liver (4, 5),4, 5 we utilized tumor/nontumor (T/N) gene-expression ratios to detect the existence of marker-positive CSCs in tumor. Accordingly, we showed that a 2-fold cutoff of T/N ratios of EPCAM successfully stratifies HCC samples with EpCAM+ liver CSCs.9, 10 A total of 95 (39.9%), 110 (46.2%),

and 31 (13.0%) of the 238 HCC cases were thus regarded as EpCAM+, CD90+, and CD133+ HCCs (T/N ratios: ≥2.0), respectively. As observed in the FACS data described above, we detected coexpression of EpCAM and CD90 in 45 HCCs (18.9%), EpCAM and CD133 in five HCCs (2%), CD90 and CD133 in five HCCs (2%), and EpCAM, CD90, and CD133 in 11 HCCs (4.6%). To clarify the characteristics of gene-expression signatures specific to stem cell marker expression status, we selected 172 HCC STI571 price cases expressing a single CSC marker (34 EpCAM+ CD90− CD133−, 49 EpCAM− CD90+ CD133−, and 10 EpCAM− CD90− CD133+) or all marker-negative HCCs (79 EpCAM− CD90− CD133−). A class-comparison analysis

with univariate F tests and a global permutation test (×10,000) yielded a total of 1,561 differentially expressed genes. Multidimensional scaling (MDS) analysis using this gene set indicated that HCC specimens were clustered in specific groups with statistical significance (P < 0.001). Close examination of MDS plots revealed three major HCC subtype clusters: all marker-negative HCCs (blue spheres); EpCAM single-positive HCCs (red spheres); and CD90 single-positive HCCs (light blue spheres). CD133+ HCCs (orange spheres) were rare, selleck products relatively scattered, and not clustered (Fig. 1B). We examined the expression of representative hepatic stem/progenitor cell markers AFP, KRT19, and DLK1 in HCCs with regard to the gene-expression status of each CSC marker (Fig. 1C). All three markers were up-regulated in EpCAM+ and CD133+ HCCs, compared with all marker-negative HCCs, consistent with previous findings.10, 11 However, we found no significant overexpression of AFP, KRT19, and DLK1 in CD90+ and all marker-negative HCCs. Hierarchical cluster analyses revealed three main gene clusters that were up-regulated in EpCAM+ HCCs (cluster A, 706 genes), EpCAM+ or CD133+ HCCs (cluster B, 530 genes), and CD90+ or CD133+ HCCs (cluster C, 325 genes) (Fig. 1D).

0001), and both 2-APB and SKF96363, store-operated calcium channels (SOCs) inhibitors, completely inhibited ATP-induced [Ca2+]i increases after restoration http://www.selleckchem.com/products/NVP-AUY922.html of extracellular Ca2+. ATP promoted the proliferation and migration of HCC cells and the growth of HCC in nude mice. Suramin, P2Y2R specific siRNA, and 2-APB inhibited ATP-induced HCC cell proliferation and migration and HCC growth (P < 0.05 and P < 0.01). Conclusion: P2Y2R was up-regulated in human HCC cells and mediated ATP-induced

human HCC cell proliferation and migration and HCC growth through SOCs-mediated Ca2+ signaling, suggesting that P2Y2R may play important role in the development and progression of inflammation-associated HCC and targeting P2Y2R may be a promising therapeutic strategy against human HCC. www.selleckchem.com/products/epz-6438.html Key Word(s): 1.

Methods: Liver abscess is most common infectious complication

during post-TACE period. Results: We describe three cases of necrotizing liver abscess after TACE in hepatocellular carcinoma. First case, a 79-year-old man, with 2.6 cm sized HCC in S4, was treated by TACE for two times during 2 months. About 1 month after the last TACE, abdominal CT scan revealed a gas containing liver abscess. Antibiotics and percutaneous transhepatic drainage was performed. selleck compound Cholangiography via drainage catheter showed

findings of bile duct necrosis. The patient improved condition and removed the catheter. Second case, a 68-year-old man, with four HCC in S4, 5, 7, 8, was treated by TACE for three times during 2 years. Two new lesions was found in S6/7, was performed by TACE. About 2 days later the patient had a fever and abdominal pain. Abdominal CT scan reveal a necrotizing liver abscess and percutaneous transhepatic drainage was performed. Two month later, the abscess improved and catheter removed. Third case, a 75-year-old man was performed embolization due to HCC rupture. After 1 month, abdominal CT scan revealed necrotizing liver abscess. Antibiotics and percutaneous transhepatic drainage was performed. However, the abscess persisted despite of treatment for 5 months. Conclusion: Physicians should be alerted to necrotizing liver abscess after TACE in patient with variable clinical manifestations.

The total cohort was split by year of diagnosis into two groups, 2000–2006 and 2007–2013 and the groups compared to evaluate trends. T-test was used to compare means and Fisher’s exact test was used to compare between groups with significance determined by p < 0.05. Results: 231 patients were diagnosed with HCC, 197 males (84.4%) with mean age of 64.1 years. 107 were diagnosed between 2000 and 2006 and 124 between 2007–2013. The groups were not statistically different with regards to age, gender, presence of cirrhosis and tumor characteristics (size and number of lesions). In the 2000–2006 group, 71%

of patients had underlying cirrhosis with an average of 1.59 lesions and average largest lesion measuring 57 mm. In the latter

group, 77% of patients had cirrhosis with an average of 1.71 lesions and average Mitomycin C largest lesion measuring 49 mm. In patients diagnosed between 2000 and 2006, Hepatitis B (HBV) was the most common risk factor for HCC, n = 29 (27.1%) followed by Hepatitis Talazoparib chemical structure C, n = 22 (20.6%). There was a decline in diagnosed HBV-related HCC, with n = 22 (17.7%) in the 2007–2013 group, although not statistically significant. There was a statistically significant increase in Hepatitis C (HCV) related HCC over time [OR: 2.21, 95% CI: 1.21 to 3.99, p = 0.009]. Numbers of HCCs secondary to Non Alcoholic Fatty Liver Disease (NAFLD) also increased significantly [OR: 7.31, 95% CI: 0.89 to 59.46 p = 0.04]. There were no significant change in the numbers of detected alcohol related

HCC’s selleck chemical between the two groups. Conclusion: There has been a decrease in Hepatitis B related HCC over time which may be attributable to the introduction of potent nucleos(t)ide analogues at our center in 2006. In contrast, there was a significant increase in HCV related HCCs and the development of strategies focused on early detection and treatment including the early implementation of more efficacious direct acting antivirals remains vital.

Background: The severity of liver fibrosis in patients with chronic hepatitis C virus infection (CHC) influences treatment decisions and surveillance for complications. In Western Australia, non-invasive assessment of liver fibrosis using transient elastography (TE) and/ or Hepascore has largely replaced liver biopsy.

4 Synchronous liver metastases represent 15–25% of all liver metastases from CRC.5–7 The optimal timing of liver surgery for resectable synchronous CLM remains controversial.8 The classical approach is first to resect the primary colorectal tumor followed by liver resection 2–3 months later. In theory, this staged approach allows selection of a biologically favorable group for liver metastases.9 However, recent advances in surgical technique

and anesthesiology of liver resection has prompted some surgeons to resect simultaneously colorectal lesions and liver metastases with a low perioperative morbidity rate, mortality rate of 0–24% and save the patients a second laparotomy.8,10,11 In addition, recent studies have demonstrated the feasibility of synchronous hepatic and colorectal resection with good short-term results.8,10,12–16 NSC 683864 The paradigm for the surgical management of synchronous CLM (SCLM) appears to change.10,12,15,16 However, the consensus has not been reached as to the safety and efficacy of simultaneous liver resection compared to staged hepatectomy. We therefore conducted this meta-analysis of published studies to compare the morbidity, mortality, intraoperative blood loss, overall survival (OS), disease-free survival (DFS), length of BVD-523 research buy hospital stay in days and

tumor recurrence at follow up of patients who underwent synchronous resection and staged resection and to assess the safety and efficacy of simultaneous resection in the management of SCLM. TO IDENTIFY ALL relevant studies that compared outcomes following simultaneous resection and staged resection for SCLM, electronic searches

were performed of the PubMed, Embase, Ovid and Medline selleck inhibitor databases from January 1990 to December 2010. The following terms were used: “synchronous”, “colorectal cancer”, “liver metastases”, “simultaneous resection”, “concurrent resection”, “staged resection” and “delayed resection”. Reference lists of all retrieved articles were manually searched for additional studies. No language restrictions were made. The inclusion criteria for study in the meta-analysis were as follows: (i) clearly document indications for simultaneous resection and staged resection for patients with SCLM; (ii) compare outcomes of patients receiving simultaneous resection of liver metastases and the primary colorectal tumor with those of patients receiving staged liver resection for SCLM; (iii) report on at least one of these outcomes: overall survival rate at 1, 3 and 5 years, disease-free survival rate at 1, 3 and 5 years, length of hospital stay, postoperative recurrence, morbidity, mortality and intraoperative blood loss; and (iv) in dual studies reported by the same institution and/or authors, either the one of highest quality or the most recent publication was included in the analysis.

All immigrants from the former USSR had one or more Jewish ancestors in various generations (or were Jews themselves). However, individuals from these separate geographical regions had very distinct cultural and socioeconomic characteristics, resembling their former non-Jewish neighbours (and are assimilated to various extents with these non-Jewish neighbours). Four HCV-infected haemophiliac siblings (Ashkenazi-1; Sephardi-3) had identical haplotype at rs12979860 – and therefore excluded. Inclusion of relatives would introduce bias and for a cohort of patients with a genetic disease this becomes a major issue. Genotypic frequencies were obtained

using Stem Cells antagonist direct counting, and statistical analysis was performed using the chi-squared test with Fisher’s exact. C-allele frequencies were calculated using the Hardy–Weinberg Equilibrium equation. The duration of HCV infection in each haemophiliac patient was estimated using a method described elsewhere [23]. P-values less than 0.05 were considered statistically significant. Calculations

were performed using sas software (SAS 9.1.3; SAS AZD1208 Institute Inc., Cary, NC, USA). The demographic and clinical characteristics of a cohort of 130 patients with haemophilia and other coagulation disorders testing positive for hepatitis C serology are presented in Table 1. Their mean age was 41 years, with an estimated duration of HCV infection of 27.1 years. There were 84 (80.8%) patients infected with HCV genotype 1:26 (20%) of the entire group were co-infected with HIV (61.5% with HCV genotype 1). A high viral load was found in 59 (56.7%), whereas 38 (29.2%) patients had advanced fibrosis (F3–F4).

Twenty-six (20%) patients tested persistently HCV RNA-negative, and were considered to have cleared HCV infection spontaneously. Fifty-one (39.2%) patients completed at least 80% of the recommended PEG–IFN/RBV dose, and 19 (37.3%) of the treated selleck inhibitor patients achieved SVR. The distribution of the various polymorphisms at SNPs rs12979860 and rs8099917 is shown in Table 2. The minor haplotype CC at SNP rs12979860 was found in 40 (30.8%) patients, whereas the major rs8099917 TT genotype was detected in 74 (56.9%) patients. Of note, genotyping was not feasible for laboratory technical issues at SNP rs12979860 in one patient, or at rs8099917 in 12 (9.2%) patients. The GG genotype at rs8099917 was only found in one patient, and therefore, for further analysis, we considered this patient together with the TG genotype, which was found in 43 (33.1%) HCV-infected haemophiliacs. SVR was achieved in 7 (70%) treated haemophilia patients who were CC homozygotes at SNP rs12979860 vs. 12 (38.7%) of the TC heterozygotes. No patient with the TT haplotype achieved an SVR (CC vs. CT or TT; P = 0.0196). Likewise, the CC haplotype was detected in seven (36.8%) of those patients achieving SVR and in only three (9.4%) non-responders.
