Human cells were allowed to engraft and to generate an immune system in recipient mice for at least 12 weeks, at which time human haematolymphoid engraftment was validated by flow cytometry on peripheral blood as described previously.6,10 Successfully engrafted mice were then randomized Ixazomib supplier based on engraftment levels for use in experiments. Dengue virus serotype-2 strain New Guinea C (DENV-2 NGC) was propagated in C6/36 Aedes albopictus cells cultured in RPMI-1640 (Invitrogen, Grand Island, NY) containing 5% heat-inactivated fetal calf serum (Gibco, Grand

Island, NY) at 28° as previously described.14 Dengue virus serotype-2 strain S16803 was kindly provided by Dr Robert

Putnak at Walter Reed Army Institute of Research. Virus titres were determined by focus-forming assay on Vero cells. Groups of BLT-NSG mice were inoculated by the subcutaneous route with approximately 106 plaque-forming units (PFU) DENV-2 NGC or increasing doses of DENV-2 S16803 (106−108 PFU). Clinical assessments (weight loss and signs of illness including ruffling and hunching) were monitored for 30 days. Organs (spleen, liver and bone marrow) selleck chemical were surgically removed from mice killed at different times post-infection. Aliquots of the sera, liver, bone marrow and spleen cells were immediately frozen at −80° for RNA analysis. A piece of the spleen, was depleted of red blood cells using an RBC lysis buffer (Sigma, St Louis, MO) and processed to make single-cell suspensions for T-cell and B-cell assays. Sera and bone marrow were tested for the presence of DENV-2 RNA by reverse transcription (RT-) PCR. Serum

viral RNA was extracted and purified using the QIAamp Viral RNA Mini kit (Qiagen, Valencia, CA). RNA from bone marrow cells was isolated using the Qiagen RNeasy mini kit (Qiagen) and subjected to reverse-transcription and amplification using a Qiagen One-Step RT-PCR Kit (Qiagen) with DENV-2-specific primers D1 and TS2 as described by Lanciotti et al.21 Viral RNA copy numbers in sera were measured by using a quantitative real-time RT-PCR-based TaqMan system (Applied Biosystems, Foster City, CA). The RNA was subjected to reverse transcription and amplification Lepirudin using a TaqMan One-Step RT-PCR Master Mix Reagents Kit (Applied Biosystems, Foster City, CA) with DENV-2 consensus primers (forward, 5′AAGGTGAGATGAAGCTGTAGTCTC-3′, and reverse, 5′CATTCCATTTTCTGGCGTTCT-3′) and DENV-2 consensus TaqMan probe (6FAM-5′CTGTCTCCTCAGCATCATTCCAGGCA-3′-TAMRA). Probed products were quantitatively monitored by their fluorescence intensity with the ABI 7300 Real-Time PCR system (Applied Biosystems). DENV-2 viral RNA was used as control RNA for quantification. Viral RNA in sera was calculated based on the standard curve of control RNA.

KOH-mounts were performed with 20% KOH and were microscopically checked for fungal elements after at least 20 min of exposure. Fungal cultures were prepared on Sabouraud glucose agars (bioMérieux, Marcy-l’Etoile, France) containing antibiotics (chloramphenicol 0.05 g l−1 selleck chemicals llc and gentamycin 0.01 g l−1) with and without addition of cycloheximide (0.4 g l−1; AppliChem, Darmstadt, Germany). The cultures were

incubated at 26 °C for at least 3 weeks before assessed as negative. Positive cultures were identified by established criteria based on morphology and physiology.12 If necessary, subcultures were prepared on special media according to the specific requirements. In particular, the urease test, cultures on potato-dextrose agar and the hair perforation test were used

if a strain could not be identified on morphological basis. The sample shares allocated to genetic analysis were submitted to DNA-extraction using a QiAmp DNA Mini Kit (Qiagen, Hilden, Germany). A PCR was then performed using a HotStarTaq Plus Master Mix Kit (Qiagen) according to the manufacturer’s instructions. The following primers were used that amplify a 280 base pair fragment containing a GT-microsatellite repeat specific for strains of the closely selleck chemical related T. rubrum/Trichophyton violaceum-clade6: forward 5′TGG TCT GGC CTT GAC TGA CC3′, reversed 5′GTA AGG ATG GCT AGT TAG GGG G3′. The fungal DNA was amplified by 30 cycles in a thermocycler (Thermomixer Comfort; Eppendorf, Hamburg, Germany): 30 s at 95 °C denaturation, 30 s DOK2 at 60 °C annealing and 45 s at 42 °C extension. The amplification product was then checked for bands with 280 bp by gel electrophoresis in a 2% agarose gel in comparison with a negative control and a positive control with DNA extracted from Trichophyton mentagrophytes (Fig. 1). For a total of 464 samples of scales, a corresponding detection of T. rubrum by PCR and culture was seen in 75

cases. A positive T. rubrum PCR, but negative T. rubrum culture, was found in 40 scale samples, whereas a positive T. rubrum culture, but negative T. rubrum PCR, was found in 13 cases. Trichophyton rubrum culture and T. rubrum PCR were both negative in 336 cases. In Fig. 2, these results are shown in rounded percentage of all scale samples. In 66 samples of scales, other fungi than T. rubrum were detected by cultures; all of these samples had a negative PCR for T. rubrum. Twenty-one scale samples were positive for fungal elements in the KOH-mounts only and were negative in cultures and T. rubrum PCR. For a total of 230 nail samples, a corresponding detection of T. rubrum by PCR and culture was seen in 40 cases. A positive T. rubrum PCR, but negative T. rubrum culture, was found in 47 nail samples, whereas a positive T. rubrum culture, but negative T. rubrum PCR, was found in 8 samples. In Fig. 3, these results are shown in rounded percentage of all nail samples. In 25 samples of nails, other fungi than T.

Data are CH5424802 datasheet expressed as means ± standard error of the mean (s.e.m.) unless stated otherwise. Statistical significance was determined with the unpaired Student’s t-test using commercially available statistic software (GraphPad Software, San Diego, CA, USA). P-values <0·05 were considered statistically significant (*P < 0·05, **P < 0·01, ***P < 0·001). To determine neutrophil purity and the overall phenotype profile of the peritoneal exudate cells 12 h post-thioglycollate-induction of peritonitis, immunofluorescence flow cytometry was performed. The data revealed a neutrophil

purity of 80%, i.e. LY6G+ cells (Fig. 1a), with clear expression of the activation molecule CD69 on these neutrophils as shown by mean fluorescence intensity (Fig. 1b). CXCR2, the major receptor for human IL-8 and the murine homologues KC and MIP-2, was expressed on 39% of the neutrophils (Fig. 1c). We were unable to evaluate the expression of CXCR1 on these neutrophils due to a lack of commercially available antibody for flow cytometry, but it is likely that the remainder of the population are CXCR1-positive. Indeed, published studies have documented a similar CXCR1 and CXCR2 expression profile on human neutrophils [24]. Thus,

the high percentage of activated neutrophils in the peritoneal exudate population demonstrates that click here these are suitable for adoptive transfer and neutrophil trafficking studies. The remaining 20% of the exudate consisted of 10% T (CD3+) and B (B220+) lymphocytes, with the rest being macrophages (F4/80+), natural killer (NK) cells (DX5+) and dendritic cells (CD11c+) (data not shown). From previous studies we know that these cell numbers are too low to visualise using this bioluminescence model; thus, the luciferase-expressing cells visible in the recipient animals should be neutrophils. To confirm the chemotactic capability of the peritoneal exudate cells, an in vitro transwell system was used. Addition of mrKC to the bottom chamber of a 96-well Neuroprobe Chemotx plate induced 5FU mobilisation of peritoneal exudate neutrophils

from the upper chamber. This migration was reduced by two different concentrations of anti-KC. In the presence of mrKC, there was an 8% increase in % neutrophil transmigration compared to the RPMI medium control, and this value was decreased to 2·8% and 1·5% by 0·1 µg/ml and 10 µg/ml anti-KC, respectively (Fig. 1d). This chemotaxis assay confirmed the suitability of the peritoneal exudate cells for adoptive transfer. Neutrophil migration towards recombinant MIP-2 instead of mrKC was also tested with similar results (data not shown). In the absence of inflammation, neutrophils (activated and responsive to KC) did not migrate to the colons of naive mice, indicating the necessity for localised gastrointestinal inflammation (Figs 4 and 5). Acute DSS colitis was therefore induced in recipient mice. Inflammation was confirmed by assessing body weight change and total DDAI (Fig.

High molecular weight chaperone complexes, hsp110- or grp170-tyro

High molecular weight chaperone complexes, hsp110- or grp170-tyrosinase-related protein 2 peptide (TRP2175–192), were superior to conventional chaperones as a vaccine platform to deliver tumour-derived antigens.[74] In addition, the immunization with chaperones combined to two different melanoma antigens (gp100, TRP2) significantly improved anti-tumour efficacy compared with either of the single antigen vaccines,[74] demonstrating that hsp combination vaccines can offer increased efficacy. In a Phase II clinical

trial, vaccination with autologous tumour-derived gp96–peptide complex vaccine (hsp complex-96) together with granulocyte–macrophage colony-stimulating factor and interferon-α was associated with mild local and systemic toxicity.[75] Vaccination was proven to instigate both tumour-specific T-cell-mediated and natural killer cell responses in some MK-2206 supplier patients. However, neither immunological nor clinical responses were improved compared with those recorded in a previous study investigating hsp complex-96 monotherapy. A recent study has provided the first evidence

in man of patient-specific immune responses against autologous tumour-derived peptides bound to gp96.[76] Over-expression of hsp70 increases significantly the immunogenicity of cancer cell extracts; with the mechanism of cell death influencing both hsp70 expression levels and the immunogenicity of cell extracts.[77] In addition SB-3CT to hsp complex from hsp70 (hsp70C), synthetic peptide-mimics of hsp70C can modulate positively Tanespimycin datasheet the immune response against tumours[78] and therefore provide an additional approach for therapeutic intervention. Heat shock protein 70 derived from tumours of characterized antigenic makeup could be used as a generic subunit tumour vaccine.[73] Vaccines derived from tumours or cell lines that have undergone heating to increase the abundance of hsp

may provide an innovative approach. For example, vaccination with heated autologous prostate cancer cells elicits protection against tumour challenge in 60% of vaccinated rats, compared with 0% protection in control rats receiving vaccines from non-shocked cells, together with an increase in the T helper type 1 (interferon-γ) response.[79] Heat shock protein 70 extracted from DC fused to patient-derived ovarian cancer or breast cancer cells (hsp70.PC-F) were tested as tumour vaccines.[80] The hsp70.PC-F induced T-cells expressing higher levels of interferon-γ and with increased killing capacity for tumour cells, compared with those induced by hsp derived from tumour cells, although these were characterized by a higher content of tumour antigens and the detection of hsp such as hsp90 and hsp110.

Genome-wide studies in human T cells have also characterized patt

Genome-wide studies in human T cells have also characterized patterns associated with promoters, enhancers and other well-conserved genomic regulatory regions.[34-38] For example, at promoter regions, H3K4me3 exists as a double peak immediately upstream of transcriptional start sites because of nucleosome depletion or Pol II binding.[34, 37, 39-42] In contrast, enhancers are characterized by the three H3K4 methylation states as well as the histone variant, H2A.Z in human T cells.[34, 38, 41] Bioinformatics analysis on 21 histone modifications in CD4+

T cells selleck inhibitor was used to classify genomic regions based on their regulatory functions. The study identified 14 distinct clusters of chromatin signatures for promoters.[43] A similar bioinformatics approach MI-503 separated 51 functionally distinct chromatin states

by using 38 histone modifications, Pol II and the insulator binding protein, CTCF (CCCTC-binding Factor). These chromatin states could be further categorized into five broad classes, namely promoter-associated states, transcription-associated states, active intergenic states, large-scale repressed states and repetitive states.[44] In addition, CpG islands have been linked with active marks like histone acetylation and H3K4me3 both in human T cells and embryonic stem cells.[35, 36, 45] Collectively, these distinct histone modifications specific to regional domains contribute to functional differences in gene regulation. Given the distinct chromatin states that govern specific regions of the genome, it is likely that genes with comparable transcription profiles

possess similar epigenetic landscapes. Genome-wide studies in human Baricitinib T cells have extensively characterized a large number of histone modifications using chromatin immunoprecipitation assays (ChIP) combined with massively parallel sequencing (ChIP-Seq) and have been particularly informative in identifying modification patterns associated with active and inactive genes.[34-38, 46, 47] In general, promoters with an active chromatin signature have intermediate to high gene expression levels but genes with low expression levels are associated with promoters with repressed chromatin signatures.[43] A major study focusing on 37 histone acetylation and methylation marks in human CD4+ T cells has shown that genes with different basal expression levels are associated with specific combinations of histone modifications.[38] A common backbone of histone modifications consisting of: histone variant H2A.Z, H2BK5ac, H2BK12ac, H2BK20ac, H2BK120ac, H3K4ac, H3K4me1, H3K4me2, H3K4me3, H3K9me1, H3K18ac, H3K27ac, H3K36ac, H4K5ac, H4K8ac, H4K91ac and H3K9ac was identified at a large number of promoters and tended to correlate with higher expression levels.

g. western and southern sub-Saharan Africa, northwestern Europe, southeastern Asia), whereas genetic profiles with intermediate frequencies for several haplotypes are observed in central or connecting regions like East Africa and the Near-East. This suggests that human peopling history occurred in a centrifugal manner, i.e. from central to peripheral regions, with a loss

of see more diversity through isolation by distance.12 This scenario is suggested by Fig. 1 (a multidimensional scaling analysis of 82 populations, data compiled in ref. 12) where a continuous pattern of genetic variation is clearly visible, and is fully compatible with the spread of modern humans towards different continents from a central region including East Africa and the Near East. Besides this general finding at the global level, the study of the GM polymorphism has brought significant results at regional levels. In Africa, linguistics this website is a better predictor of the GM genetic structure of populations than geography: variation of GM haplotypes is clearly observed among populations whose languages belong to different linguistic

phyla of this continent; i.e. Afro-Asiatic (AA), Nilo-Saharan (NS), Niger-Congo (NC) and Khoisan (KH).13–15 It is therefore likely that the spread of populations speaking languages from each of these families had a significant impact on the patterns of GM genetic variation in Africa. In particular, the demographic and geographic expansion of the NC-speaking Bantu started in a region located between present Nigeria and Cameroon and expanded southward during the last 3000 years. Bantu people may have ‘pushed’ KH populations further south compared with www.selleck.co.jp/products/Staurosporine.html the large area previously occupied by the KH populations, which extended from northeast to southern Africa. Despite documented gene flow between Bantu and KH populations, the genetic profiles (here, for the GM polymorphism) observed in KH show that they retained an ancient genetic diversification. Interestingly, KH populations exhibit

moderate frequencies for one haplotype, GM 1,17 21, which is frequent in East Africa but rarely found elsewhere in sub-Saharan Africa, indicating that KH and East African populations share ancient relationships. The other African linguistic groups also exhibit a genetic profile compatible with linguistic classification: West Africans, whose languages belong, like Bantu, to the NC family, are genetically similar to Bantu, with very high GM 1,17 5* frequencies; also, AA populations from East Africa exhibit higher frequencies of GM 1,17 21 and GM 3 5* than other sub-Saharan African populations, which makes them closer than the other groups to populations from AA-speaking populations from North Africa and the Near-East.

Data were collected and analyzed. Results: Ninety three patients were involved in this study. Data show that male : female = 46:47, age 52 ± 11, median of dialysis length 29 (7–149) months,

Kt/V 1.4 ± 0.8, average adipose tissue content was 13.01 ± 7.02 kg (23.75 ± 10.93 %), BMI 20.86 ± 3.45, median of hs-CRP 2.623 (0.177–44.139), MI score 6 ± 2. These data showed that the nutritional status measured by adipose, BMI and were still in normal find protocol range. Although Indonesian has lower BMI, they had higher percentage of adipose tissue. MIS revealed low score, accordance to hs-CRP result that also showed lower than other studies in Kaukasian and Black people. Conclusions: This study shows that hemodialysis patients in Bandung Indonesia have normal adipose tissue content, lower inflammation status, and low MI score. Key words: Adipose tissue, inflammation, MIS, hemodialysis. 245 COMPARISON OF DIALYSIS PATIENTS’ AND NEPHROLOGIST’S PERCEPTION OF SURVIVAL IN A RURAL SETTING N AUNG, S

MAY Tamworth Base Hospital, New South Wales, Australia Aim: To compare the difference between patients’ perception of their expected survival on dialysis and their treating nephrologist’s expected outcome. Background: Patients with End-Stage Renal Failure CP-673451 in vitro on dialysis are often unaware about their possible survival and this is rarely clearly discussed. Methods: Questionnaire is prepared to collect information from both patients and nephrologists about perception of

survival. We randomly select 15 patients from both in-patients and out-patients settings. Results: Patient’s median age is 64 years old (7 female, 8 male). 2 out 15 identify themselves as Indigenous and the rest are Caucasian. 60% of patients think they will survive more than 10 years but nephrologists think only 13% will. Those patients, who answered lower survival expectation, mostly had the Advanced Care Directive in place (53%). Two thirds of patient answered that a kidney transplant will prolong their survival. Nearly (14/15) would choose quality over quantity of life and their median quality of life is 7 (score from 0 to 10). Nephrologists’ Etomidate reason for low survival in 53% was due to cardiac complication and they gave high survival score in patients they assessed as eligible for kidney transplant (60%). Conclusions: There is a significant difference between the patients’ expectation of survival and their treating nephrologists’ expectation. This is an area that needs further exploration. 246 ETHICAL CONSIDERATIONS IN THE TREATMENT OF NON-ADHERENT HAEMODIALYSIS PATIENTS: BALANCING THE ETHICAL PRINCIPLES OF AUTONOMY AND JUSTICE C CORNEY1, S WINCH2 , A KARK1 1Royal Brisbane & Women’s Hospital, Brisbane, Queensland; 2The University of Queensland, Brisbane, Queensland, Australia Non-adherent haemodialysis patients present a challenge both medically and ethically.

Lack of the glomerular expression of CD2AP in animals produces heavy proteinuria. This is the first study of CD2AP gene in

SRNS patients from Indonesia. Objectives: To identify and analyse mutations on CD2AP gene in steroid resistant OSI-906 mouse Nephrotic Syndrome patients from Indonesia. Methods: DNA was extracted from peripheral blood leukocyte, using a salting-out method, primer delineated, amplification of the CD2AP exons was performed by PCR (in 18 exons), electrophoresis of PCR product were using Gel Agarose 1%, then followed with DNA sequencing and interpretation of DNA sequencing. Results: This study involved 18 subject, male 11 (61.1%), female 7 (38,9%) with age range 4–23 years. A renal biopsy was performed in 8 patients and showed focal segmental glomerulosclerosis (FSGS) in 5 patients, minimal changes nephrotic syndrome (MNCS) in 3 patients. Mutations and polymorphisms analysis of CD2AP by direct exon sequencing was performed in all 18 patients. We found 4 SNPs (single nucleotide polymorphisms) from 18 exons of CD2AP. The SNPs were in exon 4 (c.320-113 C > T), exon 11 (c. 1108 + 82 T > C), exon 16 (c.1814 + 24 G > A), exon 18 (c.1879-66 T > C). There were no mutations of CD2AP from our patients. Conclusion: From this study only found SNPs

and did not found any mutations. Further studies needed in different genes. KURIBAYASHI-OKUMA EMIKO1, HISAKI HARUMI2, OKAZAKI TOMOKI2, UCHIDA SHUNYA1 1Department of Internal Medicine, Teikyo University School of Medicine; 2Department of Biochemistry, Teikyo University School of Medicine Introduction: Steroid-resistant GSI-IX chemical structure nephrotic syndrome is intractable kidney disorder often associated with the progression to end stage renal disease. To treat steroid-resitant nephrotic syndrome, LDL-apheresis (LDL-A) has been instituted and its efficacy is reported to be about

50%. In the present study Interleukin-3 receptor the mechanism whereby LDL-A does or does not induce the remission of steroid-resitant nephrotic syndrome was investigated using the proteomic analysis of the plasma proteins adsorbed from the patients. Methods: The effect of LDL-A was assessed by the clinical indicators such as proteinuria and serum albumin. The patients were grouped as responder (n = 4) and non-responder (n = 4). The adsorbed plasma proteins were obtained at the first and the last sessions of the apheresis. Following the removal of albumin and gamma-globulin, the samples were separated by two-dimensional differential in-gel electrophoretic analysis (2-D DIGE). All spots were picked and subjected for in-gel digestion with trypsin followed by peptide analysis by MALDI-TOF/MS. Results: Since 2D patterns of the adsorbed proteins in non-responder group were almost identical between the first and the last sessions of the apheresis, we focused on the difference of 2D patterns in the first and the last sessions in responder group.

Synthesis of cDNA was performed using Superscript® III Reverse Tr

Synthesis of cDNA was performed using Superscript® III Reverse Transcriptase (Invitrogen) according to the manufacturer’s protocol. IgE and IgG heavy chain gene rearrangements were then amplified using an isotype-specific PCR. PCR amplification was performed with 100–200 ng cDNA or aliquots of the PCR1 product as templates, 0.2 μm of each primer, 200 μm of each dNTP, 1.25 units PFU polymerase (Promega, Madison, WI, USA) and a buffer supplied by the manufacturer. Details of the primers used are shown in Table 1. Specific primers

for the three large IGHV gene families (VH1F, VH3F and VH4F) were used as forward primers in separate reactions. IgG1 and IgG2 were amplified by standard PCR using appropriate isotype specific primers (G1 and G2/G4IN) as reverse ICG-001 manufacturer primers. Reactions times for this PCR were 95 °C for 3 min, followed by 35 cycles of

95 °C for 30 s, 61 °C BMS-777607 for 30 s, 72 °C for 4 min and then a final extension at 72 °C for 5 min. Semi-nested PCR were used for IgG3 (reverse primers: G3OUT and G3IN), IgG4 (G4OUT and G2/G4IN) and IgE (IGEOUT and IGEIN) sequence amplifications. PCR1 conditions used were initial denaturation at 95 °C for 3 min, followed by 35 cycles of 95 °C for 30 s, 60 °C for 30 s, 72 °C for 4 min and a final extension at 72 °C for 5 min. For PCR2, the only changed condition from those of PCR1 was the annealing temperature, which was 65 °C for IgE and IgG4, and 61.7 °C for IgG3. PCR2 was run for 25 SB-3CT cycles. All PCR were run on a Tpersonal 48 cycler (Biometra, Gottingen, Germany). PCR products were then cloned and sequenced at the Ramaciotti Centre for Gene Function Analysis, University of New South Wales, as previously described [13]. Bioinformatic analysis.  Rearranged VDJ sequences were aligned against the germline repertoire using the iHMMune-align program [19] and the UNSWIg repertoire of germline genes [20] (http://www.ihmmune.unsw.edu.au/unswig.html). This repertoire was updated with a number of IGHV polymorphisms that we have identified

in the PNG population and have submitted to GenBank (accession numbers HM855272–HM855948), as well as putative polymorphisms that have been identified in previous studies [20, 21]. Evidence in support of the existence of these putative polymorphisms within rearranged VDJ genes can be found at http://cgi.cse.unsw.edu.au/~ihmmune/IgPdb/. The number of mismatches between the germline IGHV genes and each rearranged sequence was noted. Sequences with more than 45 mismatches were removed from the data set because of the likelihood they included sequencing errors. Clonally related sequences were identified on the basis of shared IGHV, IGHD and IGHJ genes, as well as shared N regions and shared point mutations.

The level of serum FGF23 increases with developing chronic kidney

The level of serum FGF23 increases with developing chronic kidney disease. However, it is still unclear the effect of hemodialysis (HD) and type of P-binder on regulation of FGF23. We determined the change of serum FGF23 after initiation of HD and compared between calcium bicarbonate (C) and lanthanum carbonate (La) group in FGF23 regulation. Methods: Eighteen patients, introducing hemodialysis from April to September

in 2012, were participated under the informed consent. The participants were randomly divided into two groups, i.e. C and La group. Serum level of FGF23, whole parathyroid hormone (PTH), calcium and phosphate were measured at the initiation of HD and subsequent 3 months. Results: The levels Galunisertib research buy of FGF23 increased after introducing HD, although the serum phosphate was managed completely. The level of whole PTH was decreased after the starting HD. There was no significant difference in the serum FGF23 level between C and La group. Urinary P excretion was also different between them. Conclusion: Maintaining

removal of uremic substances by HD and type of P-binder did not influence the FGF23 https://www.selleckchem.com/screening/protease-inhibitor-library.html regulation. Longer observation might be needed to determine the trend of serum FGF23 in patients. HONG YU AH1, KO GANG JEE1, JUNG MI YEON1, CHO YOO SUN1, OH SOO YOUNG1, SEO JAE HEE1, PYO HEUI JUNG1, SUH SANGIL2, KWON YOUNG JOO1 1Department of Internal Medicine, Korea University College of Medicine; 2Department of Radiology, Korea University College of Medicine Introduction: Cinacalcet has been played a role in treatment of secondary hyperparathyroidism (SHPT) refractory to previous medical treatment. However, the method predicting

treatment response of cinacalcet was not established yet. We aimed to investigate whether radiologic check details examinations would be helpful to determine the response of cinacalcet treatment. Methods: The research was done with two study populations. First, 26 patients who received dialysis more than 3 months in single center were evaluated the size of parathyroid glands with three different radiologic examinations, which were sonographic measurement for diameter and volume of each gland by 3 dimentional reconstruction by one expert, and computed tomography (CT). After 20 weeks of cinacalcet treatment, predicting value of each radiological examination for the responder group who were defined as patients with PTH Results: Among 26 patients, 17 patients were responders (65.3%). Baseline serum calcium and PTH, and post-treatment ALP and PTH were lower in responder group. The means of diameter in sonography and CT, and gland volume measured by sonography were not significantly different between responder and nonresponder.
