For isolation of monocytes, the Monocyte isolation kit II (Miltenyi Biotec) was used according to manufacturer’s instructions. The untouched Selleckchem LDE225 monocytes were collected from the flowthrough and washed twice

in RPMI medium containing 2% FCS. Monocytes and DCs were cultured in RPMI1640 supplemented with 10% FCS (BioWhittaker), 2 mM l-glutamine, penicillin, and streptomycin (PAA). In order to differentiate monocytes into immature DCs, 500 IU/mL GM-CSF (ImmunoTools) and 200 IU/mL IL-4 (ImmunoTools) were added to the culture medium. The medium was changed at day 3 and cells were used for viral infection at day 6. HTNV (strain 76–118) was propagated and titrated on Vero E6 cells in a BSL3 laboratory as previously described [44, 45]. Briefly, supernatants from infected Vero E6 cells were collected at day 7–10 p.i., centrifuged at 2000 × g, and stored at −80°C. For virus titration, virus supernatant was serially diluted and incubated on Vero E6 cells for 1 h. Subsequently, cells were overlayed with agarose and incubated for 7–10 days. Agarose was removed, cells were fixed with methanol, and stained for viral N protein as Selleckchem PS 341 previously described [44]. Antigen-positive foci were counted for virus titres and expressed as focus-forming units per milliliter. VSV (strain Indiana) was propagated and titrated as previously described [21]. Titres were determined by plaque assay

on Vero E6 cells and expressed as PFU per milliliter. Cell surface staining for antigens was performed as described previously [46]. For

staining of human HLA-I molecules, a mAb (clone W6/32) was used that reacts with a monomorphic epitope of the heavy chain bound to β2m constituting the classical human HLA-I molecules (HLA-A, -B, -C). TAP1-specific mAb (clone TAP1.28) and ICAM-1-specific (clone HA58) mAb were supplied by BD Biosciences. The β2m-specific mAb (clone L368) was kindly provided by Ulrich Schaible (Borstel). The mouse IgG1 mAb (clone B5D9) for staining of intracellular HTNV N protein was PRKD3 purchased from Progen. Secondary antibodies were PE or FITC-conjugated goat anti-mouse antibodies (Dianova). For intracellular FACS staining, A549 cells were trypsinized and resuspended in DMEM containing 2% FCS. Cells were washed once with PBS. A549 cells were resuspended slowly in ice-cold ethanol and incubated at 4°C for 5–10 min. Subsequently, cells were centrifuged at 600g for 5 min at 4°C and resuspended in FACS wash buffer (PBS pH 7.4, 0.1% FCS) to rehydrate for 15–30 min. Cells were then stained with standard FACS staining procedure as described previously [46]. A549 cells treated with 2000–5000 IU/mL IFN-α (ImmunoTools) for 24 h served as a positive control for staining of human HLA-I molecules in all assays unless otherwise specified. For intracellular detection of HTNV N protein in HTNV-infected A549 cells, the Fix & Perm Kit from Caltag was used according to manufacturer’s instructions. Immunofluorescence analysis was performed as described previously [46].

These proteases may cleave extracellular matrix proteins and injure the endothelium. Lu et al. demonstrated that

ANCA-activated neutrophils released serine proteases, but not superoxide when co-cultured with EC, and that serine proteases mediated EC damage resulting in von Willebrand factor (vWF) release [78]. Serine proteases that are packaged in ANCA-induced neutrophil microparticles or in neutrophil extracellular PD0325901 price traps (NETs) possibly also participate in endothelial damage [79,80]. Together, ANCA induce a variety of neutrophil responses in vitro. Some of these were shown to be significant in vivo, such as p38 MAPK, PI3Kγ, C5a and serine proteases. Others that are thought to be important await further in-vivo proof, including the role of ANCA-induced reactive oxygen generation. The neutrophil is both the cell that expresses target

ANCA antigens and a major effector cell in ANCA-induced small vessel vasculitis. The ANCA antigens PR3 and MPO differ substantially in their expression pattern on the neutrophil plasma membrane. ANCA bind to membrane expressed target antigens and initiate intracellular signalling events. The PR3–NB1–Mac-1 membrane complex is one example showing that larger signalling complexes with transmembrane molecules exist. Distinct signalling pathways triggered by ANCA F(ab)2 and the intact ANCA IgG molecule were identified and co-operate in neutrophil activation. Detailed characterization PD-0332991 clinical trial of the activation process will identify novel treatment targets that need to be tested in animal models and subsequently in patients.

Nothing to declare. “
“Cytomegalovirus (CMV) -specific immunity is often estimated by the number of in vitro CMV antigen-inducible interferon-γ-positive

(IFN-γ+) T cells. However, recent work indicates that simultaneous production of IFN-γ, tumour necrosis factor-α (TNF-α) and interleukin-2 (IL-2) (referred to as ‘polyfunctionality’) is more relevant for anti-viral protection. Here, we compared polyfunctionality of CMV-specific T cells (pp65 and IE-1 proteins) in 23 solid-organ transplant patients and seven healthy controls by flow cytometry. The proportions of TNF-α+/IFN-γ+/IL-2 cells among the activated cells were significantly reduced in transplant patients but not the frequencies of IFN-γ+ CD8+ T cells. Immunosuppression reduces polyfunctionality, which reflects the increased infection risk in this patient group. In healthy individuals, CD4+ and CD8+ T cells restrain many infectious pathogens but in transplant patients these mechanisms are weakened by the immunosuppressive medication required to prevent graft rejection.

The recombinant protein was expressed in soluble form with His tag at the N-terminus. The positive clone was bulk-cultured, and the pellet was stored at −20°C. It was thawed, and 4 volumes of lysis buffer (20 mm sodium phosphate (pH 7·4), 1 m NaCl and 1 mg/mL lysozyme) was added. After mixing, the tube was kept in ice Selleckchem Cobimetinib for 30 min, and the suspension was sonicated thrice at 10 Hz for 1 min. The sonicated bacterial pellet was centrifuged at 11 000 g for 15 min at 4°C. The supernatant was collected and passed through a Ni–agarose column. The column was washed with excess buffer and then eluted with increasing concentrations of imidazole (5–250 mm). The presence of protein in the eluted fractions was

checked by SDS gel electrophoresis and Western blot using anti-H.c-C3BP antiserum. The enzyme activity of the recombinant GAPDH and its interaction with C3 were studied as described above. SDS-PAGE was carried out in 5–15% linear gradient gels in discontinuous buffer system. Occasionally, protein samples were reduced by adding 2-mercaptoethanol (2% final concentration). Protein bands were visualized by staining with Coomassie Brilliant Blue R-250. For Western blot, proteins CP-673451 mouse were transferred from gel

to nitrocellulose membrane at 200 mA for 90 min. Primary antibody was used at 1 : 250 or 1 : 500 dilutions and secondary conjugated antibody at 1 : 500 dilutions. For antibody production, H.c-C3BP (25–50 ug/mL) was fractionated on a SDS gel, and the lightly stained gel band region around the 14-kDa band was excised with a blade, washed with several changes

of PBS and homogenized in Freund’s complete adjuvant. The emulsion was used for immunizing two healthy male rabbits. Booster doses were given every third week with the same amount of protein in incomplete adjuvant. Blood was collected a week after the last immunization, and the presence of antibodies was checked selleck chemical by Western blot. Animal experimentations were performed as per the guidelines of the animal ethics committee of the institute. All the data were analysed by GraphPad prism 4 software using one-way anova. A P value <0·05 was considered significant. To identify the C3-binding protein in H. contortus, a simple strategy of using C3–Sepharose was followed. On passing the ES products of adult H. contortus through C3–Sepharose column, a band of ~14 kDa was observed in the SDS gel of the eluted fraction after staining with Coomassie Brilliant Blue (Figure 1a). This band was consistently observed in all batches of ES products. This observation was confirmed by immunoprecipitation analysis. The immunoprecipitates formed as a result of C3 and ES products interaction showed a ~14-kDa band, which was absent in the C3 protein lane (Figure 1b). To evaluate the existence of H.c-C3BP in the adult worms, Western blot analysis was performed using antiserum raised against the ~14-kDa band. Adult parasites showed different pattern.

At 46 days of age, the chickens in each group were challenged i.v. with 0.5 mL of a bacterial suspension containing 108 CFU/mL of E. coli O78 strain J46, which harbors the iss, tsh cvaC, and papC genes. APO866 The LD50 value of this challenge strain for i.v. infection against 5-week-old chickens is 2.9 × 107 CFU /bird. The challenged chickens were observed for 7 days, and their clinical signs scored as follows: none = 0, reluctance to walk = 1, mild depression or ataxia = 2, depression or astasia = 3, death = 4. Dead chickens were necropsied immediately on the day of death. Seven days after challenge exposure, the surviving chickens

were killed and necropsied. Macroscopic lesions were recorded and scored separately for each organ as follows: heart and pericardium (normal = 0, turbid with excessive or cloudy fluid in the pericardial cavity or partial pericarditis = 1, marked pericarditis = 2, severe pericarditis or death = 3); liver (normal = 0, small amount of fibrinous exudate = 1, marked perihepatitis = 2, severe perihepatitis or death = 3). Samples for bacteriologic examination were taken from the liver and heart of each chicken at necropsy. Twenty 19-day-old embryonated eggs

were allotted to two equal groups and immunized with AESN1331 or sterile PBS. Each egg was oriented with MK0683 molecular weight the large end up and a hole punched in its top with an 18-gauge needle. Using a 21-gauge needle, an inoculum of 10 μL (103 CFU) of AESN1331 per egg (or an equivalent volume of PBS) was injected into the amniotic fluid. All inoculated eggs were then hatched in the same incubator. Hatching was assessed after 21.5 days of incubation. Until exposure to challenge, the hatched chickens were monitored daily for signs of illness and for death. At 28 days of age, all chickens were challenged and assessed as described above. Fisher’s exact test was used to compare the number of dead chickens and the number of organs positive for the challenge MycoClean Mycoplasma Removal Kit strain in each group. Student’s two-tailed t-test was employed to compare the clinical and the lesion scores between experimental groups. A P value of < 0.05 was considered significant. We compared the in

vitro and in vivo properties of the mutant strain to those of the parent; results are summarized in Table 1. As with the parent, E. coli O78 antiserum agglutinated AESN1331. Colonies of the mutant were smaller than those of the parent. AESN1331 colonies were colorless on MacConkey agar, demonstrating an inability to ferment lactose. AESN1331 also was unable to ferment D-mannose, D-sorbitol, L-rhamnose, sucrose and D-melibiose, but could still ferment glucose and L-arabinose. Although the mutant had lost tryptophan deaminase activity and indole production, the strain resembled its parent in harboring β-galactosidase, lysine decarboxylase, ornithine decarboxylase, and oxidase activities while lacking arginine dihydrolase, citrate production, H2S production, urease, acetoin production, gelatinase, and ability to reduce NO3− to NO2−.

Serological diagnosis was performed using an enzyme-linked immunosorbent assay (ELISA) (10), and parasitological diagnosis of VL was achieved by detecting the typical amastigotes forms of Leishmania in cytological examinations of tissue smears of the popliteal lymph node. Immunofluorescence tests were conducted to exclude toxoplasmosis and neosporosis, and dogs with antibody titres greater than or equal to 1 : 16

and 1 : 50, respectively, were considered seropositive and were not included in this study. Cerebrospinal fluid samples were obtained by puncture of the cisterna magna following anaesthesia with sodium pentobarbital (Hypnol 3%). All CSF samples included in the study demonstrated no signs of blood contamination. The samples were centrifuged at 12 000 g for 15 min at 4°C, and the https://www.selleckchem.com/products/DAPT-GSI-IX.html supernatant was separated

Erastin clinical trial and kept frozen at −20°C until further analysis (11). Total protein was quantified using the bicinchoninic acid (BCA) method (23225; Pierce Biotechnology, Rockford, IL, USA). Zymographic evaluation was conducted according to the method previously described (12) with slight modifications. Briefly, samples containing an equal amount of total protein were incubated in the sample buffer (125 mm Tris–HCl pH 6·8; 20% glycerol; 4% SDS; 0·2% bromophenol blue) and then electrophoresed through a 10% polyacrylamide gel that was copolymerized with gelatin (G8150-100G; Sigma-Aldrich, Saint Louis, MO, USA). The gels were then rinsed in 2·5% Triton X-100 for 30 min and incubated in the enzyme activation buffer (50 mm Tris; 200 mm NaCl; 5 mm CaCl2; 0·2% Brij-35, pH 7·5), for 20 h at 37°C with gentle shaking. The gels were incubated in staining buffer (0·5% Coomassie brilliant blue R-250; 45% methanol; 10% glacial acetic acid) for 30 min and then destained in the same solution without the dye

for 45 min. As a positive control, human recombinant MMP-2 (72-kDa latent form and 66-kDa active form; PF037; Calbiochem, San Selleckchem Regorafenib Diego, CA, USA) and MMP-9 (92-kDa latent form and 86-kDa active form; PF038; Calbiochem) were used. Gelatinolytic activity is indicated by the presence of a clear band against the dark blue background. The gels were digitally scanned, and the integrated density of the bands, expressed as arbitrary units, was calculated using the open-access software ImageJ 1.41o (Wayne Rasband, National Institutes of Health, Bethesda, MD, USA; http://rsb.info.nih.gov/ij). The significance of any difference in the MMP-2 levels was determined using the Student’s t test with Welch’s correction, while for the MMP-9 levels, the significance was assessed by the Wilcoxon Signed Rank Test. The correlation between the latent and active forms of the enzymes was measured by linear regression. A value of P < 0·05 was considered statistically significant. All statistical analyses were performed using Prism 5 software (GraphPad, La Jolla, CA, USA).

alcalifaciens O5 and P. stuartii O18 (titers 1 : 16 000 selleck compound and 1 : 8000, respectively). Comparison of the O-antigen structures of these strains (Fig. 4, structures 2 and 3) showed some similarities between them. Particularly, the three O-antigens contain d-Qui3N derivatives [N-formyl in P. alcalifaciens O40 or N-acetyl in P. alcalifaciens O5 (Zatonsky et al., 1999) and P. stuartii O18 (Kocharova et al., 2004)], which occupy evidently the nonreducing end of the polysaccharide chain. In addition, P. alcalifaciens O40 shares

β-d-Quip3NFo/Ac-(13)-α-d-Galp and β-d-GlcpA-(13)-d-GalpNAc disaccharide fragments of the O-antigens with P. alcalifaciens O5 and P. stuartii O18, respectively. It is most likely that epitopes associated with the partial structures in common are responsible for the observed serological cross-reactivity. The chromosomal region between the housekeeping genes cpxA and yibK in P. alcalifaciens O40 was sequenced, and a nucleotide sequence of PLX-4720 price 19 442 bp was obtained. The overall G + C content of the O-antigen gene cluster is 35.5%, which is lower than the average level of P. alcalifaciens genome (about 41%). A total of 16 individual open reading frames (ORFs) were identified, all of which have the same transcriptional direction from cpxA to yibK (Fig. 5). The ORFs were assigned functions based on their similarities to those from available

databases and are summarized in Table 2. The biosynthesis of dTDP-d-Quip3NAc recently described in Thermoanaerobacterium thermosaccharolyticum E207-71 (Pfoestl et al., 2008) involves Oxaprozin five enzymes: RmlA, RmlB, QdtA, QdtB, and QdtC. The pathway starts from glucose-1-phosphate,

which is converted into the activated dTDP-d-glucose form by glucose-1-phosphate thymidylyltransferase RmlA. The product is dehydrated by dTDP-d-glucose-4,6-dehydratase RmlB to give dTDP-6-deoxy-d-xylo-hexos-4-ulose, which is a common intermediate in synthesis of many different sugars (Hao & Lam, 2011). Orf3 shows 78% identity or 88% similarity to RmlA of Shewanella oneidensis MR-1. High identity was also observed between orf3 and rmlA genes of a number of other bacterial strains. No gene within the O40-antigen gene cluster shows any homology with rmlB, and we proposed that rmlB is located outside the O40-antigen cluster. Orf4 shares 52% identity or 67% similarity with isomerase QdtA of T. thermosaccharolyticum, which catalyzes conversion of dTDP-6-deoxy-d-xylo-hexos-4-ulose to dTDP-6-deoxy-d-ribo-hexos-3-ulose. Orf5 belongs to the aspartate aminotransferase superfamily (Pfam01041, E value = 6 × e−106); it shares 56% identity or 75% similarity to FdtB from Escherichia coli O114, which is involved in biosynthesis of dTDP-d-Fucp3NAc (Feng et al., 2004) and is a homologue of QdtB. Both QdtB and FdtB are transaminases capable of synthesizing the respective 3-amino-3,6-dideoxyhexoses. Orf5 was proposed to have the same function as QdtB.

Also, drugs, malignancies and diseases which cause protein and/or lymphocyte loss may cause secondary immunodeficiency; this is more common than unrecognized PID in adults [5]. It is important to eliminate these

learn more possibilities before making a definitive diagnosis of PID. Many new PIDs have been identified in the past decades, and more are likely in the near future, so this multi-stage diagnostic protocol will need to be revised from time to time. The key to detect a PID is to consider the possibility. This work was supported in part by the NIHR Biomedical Research Centres funding scheme (K. Gilmour) and BMBF PIDNET (C. Klein), which enabled them to spend time on the multi-stage diagnostic protocol for suspected immunodeficiency. P.

Although there was no significant difference (r= 0.98) between cholesterol removal by resting and dead cells, most strains exhibited higher cholesterol removal when resting cells were suspended

in phosphate buffer (pH 6.8) compared to heat-killed cells (Fig. 1). Moreover, the amount of cholesterol removed by the cells during growth was significantly higher compared to the cholesterol removed by heat-killed and resting cells (P < 0.01). In this www.selleckchem.com/products/Everolimus(RAD001).html study, for all three cell types (growing, resting, and heat-killed cells), the highest cholesterol removal was by the B3 strain (23%, 14% and 10%, respectively). All of the strains produced more EPS in the presence of cholesterol than the strains grown without cholesterol during the 19-hr incubation period (Fig. 2). In other words, cholesterol significantly

stimulated the EPS production and the Pearson correlation coefficient was statistically significant (P < 0.01). It is remarkable that at the end of the 19- and 48-hr incubation periods, in the media containing 1 mg/ml oxgall, the B3 strain, which achieved maximum cholesterol removal to the values of 34% and 40%, respectively, had the highest EPS production (211 mg/l) capacity. Furthermore, the ATCC 11842 strain, which had the second highest EPS production capacity (200 mg/l), also had the second highest cholesterol removal rate after the B3 strain. For the immobilization study, among the five strains tested, the B3 strain, which had this website the highest EPS production and cholesterol removal capacity, was selected. Observable differences were found in cholesterol removal by immobilized and free B3 cells (Table 3). For both of the incubation periods (19 hr and 48 hr), immobilized cultures exhibited higher cholesterol removal ability compared to the free

cells. The highest cholesterol removal (50%) was achieved by the immobilized B3 strain at the end of 2-hydroxyphytanoyl-CoA lyase the 48-hr incubation period. The viable cell counts in free and immobilized cultures at the end of the 19- and 48-hr incubation periods are shown in Table 4. After 19-hr incubation, in the PBS buffer solution containing 100 μg/ml cholesterol plus 3 mg/ml oxgall, the immobilized B3 culture contained 6.5 ± 0.2 × 103 cfu/ml, which represented 72% of surviving bacteria. In contrast, after 48-hr incubation, it contained 1.8 ± 0.2 × 102 cfu/ml, which represented a 51% survival rate. These results are higher than those observed with free cells. Coronary heart disease is one of the major causes of death and disability in many countries (21). Elevated levels of serum cholesterol is also a risk factor for the development of atherosclerotic vascular disease (22). Drug therapy for hypercholesterolemia includes fibrates, statins and bile acid sequestrants; however the undesirable side-effects of these compounds have caused concerns about their therapeutic use.

1A, the expression of mRNA for TNFR2, OX40, 4-1BB and GITR was two-fold higher in freshly isolated Tregs than freshly isolated Teffs. After treatment with TNF/IL-2, the expression of mRNA for

these TNFRSF members and FAS was at least two-fold higher in Tregs than in Teffs. Treatment with TNF/IL-2 further up-regulated the mRNA expression greater than four-fold in Tregs, as compared with freshly isolated Tregs (Fig. 1A). Thus, in the presence of IL-2, TNF up-regulated the gene expression of TNFR2 and other co-stimulatory TNFRSF members in Tregs. Treatment with TNF/IL-2 for 3 days preferentially up-regulated the surface expression of TNFR2, OX40, 4-1BB and FAS on Tregs but not on Teffs (Fig. 1B). TNFR2, OX40 and 4-1BB expressed on IL-2/TNF-treated Tregs were increased by 2.1±0.2, 2.4±0.2 and 6.0±0.7 fold respectively, over their expression on freshly isolated Tregs (p<0.05–0.001, find more Fig. 1C). ABT-263 IL-2 alone also increased their surface

expression (p<0.05); however, addition of TNF further increased their expression by up to ∼two-fold over IL-2 alone (p<0.05–0.01, Fig. 1C). TNF-induced up-regulation in the case of TNFR2 was dose-dependent (Fig. 1D). TNF was also able to up-regulate surface expression of TNFR2, OX40 and 4-1BB on FACS-purified CD4+FoxP3/gfp+ Tregs (data not shown), indicating that TNF directly acts on Tregs. The increased expression of these co-stimulatory TNFRSF members has been reported to be a consequence of the activation of CD4+ T cells 21. Indeed, IL-2/TNF treatment markedly and preferentially enhanced the expression of the activation

markers, CD44 and CD69, on Tregs (Fig. 1B). Therefore, IL-2/TNF led to greater activation of Tregs. It is possible that TNF, in addition Loperamide to expanding TNFR2+ Tregs, also converts TNFR2− Tregs into TNFR2+ Tregs. To test this, flow-sorted CD4+FoxP3/gfp+TNFR2− cells and CD4+FoxP3/gfp−TNFR2− cells were treated with IL-2 or TNF/IL-2. As shown in Fig. 2A, IL-2 alone induced the expression of TNFR2 on FoxP3/gfp+TNFR2− Tregs. Presumably based on the initial induction of TNFR2 by IL-2, TNF further amplifies the expression levels of TNFR2 on FoxP3/gfp+TNFR2− Tregs (p<0.001). In contrast, neither IL-2 nor TNF/IL-2 was able to induce TNFR2 expression on FoxP3/gfp−TNFR2− Teffs (Fig. 2B). Thus, TNF does have the capacity to induce nonfunctional TNFR2− Tregs into functional TNFR2+ Tregs. Treatment with TNF/IL-2 was previously shown to up-regulate the expression of CD25 on Tregs 3. Thus, the activating effects of TNF/IL-2 on Tregs and their stimulation of TNFR2 expression may depend entirely on the enhanced interaction of IL-2 with CD25. To test this hypothesis, we examined the effect of the combination of TNF and IL-7, another cytokine that uses the common γ chain and maintains the survival of Tregs in vitro 22. Only 6% of Tregs, and approximately the same proportion of Teffs, were induced to proliferate when CD4+ T cells were cultured with IL-7 alone (Fig.

WANG KU-CHUNG, KUO LI-CHUEH, CHEN JIN-BOR Division of Nephrology, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University College of Medicine, Kaohsiung Introduction: The aim of study was to investigate the influences of clinical variables https://www.selleckchem.com/products/PLX-4032.html on the quality of life (QoL) in incident peritoneal dialysis (PD) patients. Methods: The study was a prospective, case-control, observational design. Fifty-three incident patients who received chronic PD in one PD unit were enrolled. The mean age was 48.3 ± 12.6 year-old, men to women 21:32. The observational period was two years. SF-36 health survey questionnaires

were used to measure the QoL. Comparable variables included epidemiology, social status, concomitant medical status and biochemical data. Results: The scores of SF-36 components before PD therapy were general health 58.48 ± 20.05, pain 38.64 ± 21.84, social functioning 64.62 ± 27.54, emotional well-being 48.48 ± 18.29, energy/fatigue 56.82 ± 21.59, role limitations due to emotional problems 68.69 ± 15.74, role limitations due to physical health 54.88 ± 15.19, physical functioning 65.09 ± 20.24. After six months PD therapy, unmarried subjects demonstrated higher scores in role limitations due to emotional problems (76.19 vs 47.75, p < 0.05), role

limitations due to physical health (66.07 vs 37.16, p < 0.05) than married subjects. At the end of twenty-four months PD therapy, subjects who exchanged PD fluid by selleck screening library themselves showed higher scores in social functioning and physical functioning compared to those

exchanged PD fluid by assistants. Furthermore, subjects with antihypertensive demonstrated higher scores in emotional well-being than those without antihypertensive. Conclusion: PD therapy had sequential influences on the components of QoL in term of PD duration. At 6-month PD therapy, marriage status had a positive influence on QoL. In contrast, self-care and antihypertensive use had a greater contribution on QoL improvement at 24-month PD therapy. Therefore, patient-oriented PD care should be implanted into contemporary situation of PD patients.
