In recent years, adoptive transfer of Treg cells has gained major attention as an alternative or complementary therapy to conventional immunosuppressive treatments with the ultimate

aim of reducing the side effects of conventional drugs [12, 13]. Since only 5–10% of the circulating CD4+ cells in an organism are Foxp3+ Treg cells, their potential use for cell therapy seems to be limited and the peripheral population would require expansion [14]. Isolated CD4+CD25+ cells frequently undergo expansion in the presence of aCD3/ aCD28 Ab and IL-2. Allo-specific expanded Treg cells seem to be more potent in suppressing chronic rejection, graft versus host disease (GvHD) and autoimmune diseases than polyclonal Treg cells. EGFR activation For example it was shown that antigen-specific expanded Treg

(alloreactive Treg (aTreg)) cells could suppress experimental autoimmune diabetes more effectively than polyclonally X-396 solubility dmso expanded Treg cells [15]. We have shown previously that in vitro culture of total murine CD4+ or CD25−CD4+ cells in the presence of alloantigen and a nondepleting anti-CD4 antibody results in the enrichment of CD25+CD62L+Foxp3+ T cells effective in controlling graft survival in vivo in an alloantigen-specific manner [16]. Although the in vitro enriched aTreg cells were effective in vivo, the protocol still has some limitations. To obtain almost pure Treg-cell populations, high anti-CD4 antibody concentrations had to be used, which led to a dramatic reduction in absolute cell numbers. Here, we have investigated whether we can reduce the anti-CD4 antibody concentration needed to enrich aTreg cells by adding Treg-favouring agents such as TGF-β [17] and 6-phosphogluconolactonase retinoic acid (RA) [18] or rapamycin (Rapa) [19] and thereby achieve higher numbers of stable and efficient aTreg cells. The addition of both TGF-β and RA or Rapa to suboptimal anti-CD4 antibody concentrations resulted in increased purity and absolute

numbers of Foxp3+ Treg cells. Importantly, aTreg cells generated by the addition of TGF-β+RA displayed the lowest production of inflammatory cytokines and expression of CD40L, but the highest stability and regulatory potential in vitro and in vivo. Interestingly, nearly all of the aTreg cells obtained under these conditions co-expressed Helios and Neuropilin-1. Indeed, aCD4+TGF-β+RA aTreg cells could ameliorate GvHD and delay rejection of skin transplants in very stringent in vivo models. Addition of TGF-β+RA or Rapa to the nondepleting anti-CD4 antibody enhanced aTreg-cell induction in vitro (Fig. 1). The treatment with TGF-β+RA or Rapa increased the frequency of CD4+CD25+Foxp3+ Treg cells compared with that of untreated cultures or cultures only treated with the aCD4. We could detect an average percentage of over 60% of aTreg cells in cultures treated with aCD4+TGF-β+RA or aCD4+Rapa (Fig. 1A) within the CD25+ population.

Molecular epidemiological studies have shown that all major subtypes, including B, C, B’, BC and AE recombinant forms, exist in China, and recombinant subtypes are more prevalent [17]. In this study, we analysed the neutralizing activities of 80 serum samples derived from Chinese HIV-1 patients against a panel of HIV-1 clinical isolates and identified 8 cross-clade neutralizing sera (CNsera). We conducted further immunological characterization of the 8 CNsera to investigate the epitope specificities of the serum antibodies and the relationships to the cross-clade neutralization activity. The study shed light on the basic immunological

properties of the antibodies induced by infections of diverse viral isolates and the epitopes that mediate the cross-clade neutralizing Rucaparib purchase activities. Sera were provided by Beijing YouAn Hospital. All sera were collected from Chinese individuals infected with HIV-1 through injection drug use, sexual intercourse or commercial blood donation after informed consent was obtained. This study was approved by the institutional review board at the YouAn Hospital and Nanjing University. GHOST(3)X4/R5, 293T cell line, PNL4-3 LucR−E− and Env-expressing plasmids were kindly provided by Prof. Linqi Zhang of Comprehensive AIDS Research Center, at Tsinghua University. Mutant

Env plasmids CNE6N160K and CNE55N160K were generated using the QuickChange mutagenesis kit (Stratagene, La Jolla, CA, USA). DMEM (high glucose), Opti-MEM, trypsin and fetal bovine serum were purchased from Gibco Biotechnology Inc. (Rockville, medroxyprogesterone MD, USA). All peptides were RAD001 synthesized by GL Biochem Ltd. (Shanghai, China), and the sequences were shown in Table 1. Monoclonal antibodies (mAbs) b12, 2G12, 2F5, 4E10 and 447-52D were purchased from POLYMUN Scientific Inc. (Klosterneuburg,

Austria). Gp120IIIB, gp120JRFL, gp120JRFLD368R, gp120BC and gp120AE were purchased from HaiYuan Inc. (Taizhou, China). Mammalian cell codon-optimized V1V2BAL DNA sequences were synthesized by Invitrogen Inc. (Shanghai, China) and inserted into pTriEx-3 Hygro expression vector. V1V2BAL protein was expressed by transfecting Freestyle 293 (293F) cells in serum-free medium (Invitrogen, Carlsbad, CA, USA). Briefly, codon-optimized expression plasmid was transfected into 293F cells using PEI (Polysciences, Eppelheim, Germany) when the density of 293F cells reached 1.0 × 106/ml. The final concentrations of the plasmid and PEI were 1 μg/ml and 2 μg/ml, respectively. Supernatants were collected 6 days after transfection and concentrated using labscale tangential flow filtration cassette and system (Millipore, Billerica, MA, USA). V1V2BAL protein was purified by SwellGel Nickel-chelated discs (Pierce, Rockford, IL, USA), according to the manufacturer’s instructions.

However, this only reached significance for patients with orophar

However, this only reached significance for patients with oropharyngeal cancer. It has been demonstrated in previous publications that cells expressing high levels of the IL-2 receptor (CD4+ CD25high) have the capacity to inhibit the proliferation of effector T cells, whereas cells expressing intermediate/low levels of CD25 do not.[20, 37] In contrast, the current study demonstrated that the CD127low/− Treg cell find more population expressing intermediate levels of CD25 consistently induced a greater level of suppression compared with those

cells expressing high levels of the IL-2 receptor, reaching significance for healthy controls and a number of different HNSCC patient subgroups on TAM Receptor inhibitor both effector T-cell populations. Although not previously assessed in cancer patients, the level of suppression induced by CD127low/− Treg cells separated by different levels of CD25 expression has been examined in healthy controls where it was shown that CD127low T cells expressing high and intermediate/low levels of CD25 both have the capacity to suppress the proliferation of effector T cells to a similar extent.[23, 24, 38] Treg cells are widely accepted as being anergic in vitro but this anergy can be broken under suitable conditions.[39] It is therefore unknown, whether the increase

in suppressive activity observed by the CD25inter Treg cells compared with that induced by the CD25high Treg cells, is a result of their expansion during co-culture or of an increased ability to suppress effector T-cell proliferation. The current study has highlighted how distinct populations of cells, identified on the basis of expression levels of surface markers, show significantly different biological effects; however, these cell populations should not be considered as static entities. For instance Hartigan-O’Connor et al. suggested that the CD25inter CD127low/− cells may contain precursors to fully activated CD25high CD127low/− Treg cells, and demonstrated during 64 hr of stimulation, that the CD25inter CD127low/−

cells up-regulated the expression of CD25 and Foxp3, coupled with down-regulation of CD127.[38] Hence it is conceivable that the Treg cell populations could develop during assay incubation periods and acquire Dichloromethane dehalogenase or lose functional capabilities. In summary, newly presenting HNSCC patients with tumours that have metastasized to the lymph nodes have been shown to be associated with an elevated frequency and suppressive activity of peripheral CD25high Treg cells, and patients with advanced stage tumours have been found to have an increased level of Treg cells identified by the same phenotype. In addition, CD25inter Treg cells induced the highest levels of suppression for healthy controls and HNSCC patients, regardless of tumour subsite, stage or nodal involvement.

In doing so, a window of STI vulnerability is created during which potential pathogens including HIV enter the reproductive tract to infect host targets. “
“An expanding spectrum of acute and chronic non-infectious inflammatory diseases is uniquely responsive to IL-1β neutralization. selleckchem IL-1β-mediated diseases are often called “auto-inflammatory” and the dominant finding is the release of the active form of IL-1β driven by endogenous molecules acting on the monocyte/macrophage. IL-1β activity is

tightly controlled and requires the conversion of the primary transcript, the inactive IL-1β precursor, to the Venetoclax concentration active cytokine by limited proteolysis. Limited proteolysis can take place extracellularly by serine proteases, released in particular by infiltrating neutrophils or intracellularly by the cysteine protease caspase-1. Therefore, blocking IL-1β resolves inflammation regardless of how the cytokine is released from the cell or how the precursor is cleaved. Endogenous stimulants such as oxidized fatty acids and lipoproteins, high glucose

concentrations, uric acid crystals, activated complement, contents of necrotic cells, and cytokines, particularly IL-1 itself, induce the synthesis of the inactive IL-1β precursor, which awaits processing to the active form. Although bursts of IL-1β precipitate acute attacks of systemic or local inflammation, IL-1β also contributes to several Histidine ammonia-lyase chronic diseases. For example,

ischemic injury, such as myocardial infarction or stroke, causes acute and extensive damage, and slowly progressive inflammatory processes take place in atherosclerosis, type 2 diabetes, osteoarthritis and smoldering myeloma. Evidence for the involvement of IL-1β and the clinical results of reducing IL-1β activity in this broad spectrum of inflammatory diseases are the focus of this review. IL-1 has a long history 1; it begins with interest in the most salient manifestation of inflammation, fever. Indeed, the discovery of IL-1 as the quintessential inflammatory cytokine can be traced to the purification of the endogenous fever-producing molecule, leukocytic pyrogen, in 1977 2. Interest in this molecule increased when we reported that leukocytic pyrogen was the same molecule as lymphocyte activating factor 3, thus necessitating invention of the IL nomenclature. The term for IL-1 was assigned to the macrophage product and IL-2 for the T-cell product, even though there was no N-terminal amino acid sequence at that time that these were indeed different molecules.

However, the high stimulation levels as induced by the adherent s

However, the high stimulation levels as induced by the adherent splenic cells from B10.Q.Ncf1*/* mice were PF-01367338 nmr not reached. This indicates that in B10.Q mice also other APC are involved, most likely DC. Since CD11c+ DC do not express Aq in MBQ mice, they cannot be accounted for the T-cell stimulation elicited by adherent splenic cells from these mice. In the absence of CII, no detectable IL-2 was produced (data not shown). Contrary to the whole CII molecule, a peptide with high affinity for the MHC II could be presented to the specific T-cell hybridoma with the same efficiency by adherent splenic cells, regardless of their capacity to produce ROS (Supporting

Information Fig. 3). APC expressing Ap or Aq could present this equally well, as previously described 9. To investigate T-cell responses in immunized mice, IFN-γ ELIspots were performed using draining Proteasome inhibition assay (inguinal) lymph node (LN) cells from 10 days immunized B10.P.Ncf1*/*.MBQ or B10.P.Ncf1*/* mice. T cells from B10.P.Ncf1*/*.MBQ LN produced a higher number of IFN-γ

spots as compared to B10.P.Ncf1*/* mice, indicating that also in vivo T cells can be activated by Ncf1*/* macrophages (Fig. 3B). Similar results were obtained with IL-2 production assays of LN cells restimulated with lathyritic CII (data not shown). Next, we investigated if arthritis could be induced when macrophages are the only Nutlin-3 chemical structure APC that can present the antigen. Arthritis was induced in B10.P.MBQ transgenic mice with different Ncf1 genotypes or littermate B10.P.Ncf1*/* mice. Only B10.P.Ncf1*/*.MBQ mice

developed arthritis (Fig. 4A) with an incidence of 40% (Fig. 4B). Expression of Aq on macrophages thus allowed CII presentation in vivo but deficiency in ROS production was required to sufficiently prime and activate autoreactive T cells. Anti-CII antibody levels were determined in sera from these mice 79 days after immunization (Fig. 4C). No difference was observed between B10.P.Ncf1*/*.MBQ and B10.P.Ncf1*/* mice, suggesting that the MBQ transgene did not allow increased activation of anti-CII B cells. The difference in anti-CII IgG between B10.P.Ncf1*/*.MBQ and B10.P.Ncf1*/+.MBQ and B10.P.Ncf1+/+.MBQ suggests that Ncf1 has a role in determining the threshold of activation of B cells. Here, we show for the first time that in the absence of ROS, macrophages are able to prime naïve T cells in vivo, resulting in development of CIA in mice. These data suggest that macrophages have contact with naïve T cells in an antigen-dependent way, but that in an ROS sufficient situation this interaction results in suppression of activation. A physiological explanation for this phenomenon could be that ROS secreted by antigen presenting macrophages might protect against a continuous and aberrant T-cell activation leading to chronic inflammation.

It was found that, before 2001, B51+ individuals displayed

significantly lower pVL than the other patients (median: 5150 vs. 18 000 RNA copies/ml, P= 0.048); however thereafter this protective effect waned and disappeared, whereas no changes were observed for any other alleles over time. These results indicate that, at a population level, some HLA alleles have been losing their beneficial effects against HIV disease progression over time, thereby possibly posing a significant challenge for HIV vaccine development. However such detrimental effects 3-deazaneplanocin A in vivo may be limited to particular HLA class I alleles. HIV-1 is the causative agent for AIDS. Since the discovery of HIV-1 in 1983, although a myriad of studies focusing on the immunopathogenesis of HIV-1 infection have been conducted, a number of questions remained unanswered, hampering development of HIV/AIDS vaccines. As the HIV-1 epidemic has continued, it has become evident that the rate of decline in CD4+ T cells varies considerably between infected people, and that untreated individuals with larger pVL during the asymptomatic phase of infection progress to AIDS more rapidly than those with lower pVL (1, 2). Host genetics, host innate and adaptive immune Selleckchem Navitoclax responses, and

viral sequence variations have all been suggested as possible factors influencing the level of viremia and disease outcome (3–5). Amongst host genetic factors, HLA class I types are recognized to be the most influential with respect to disease progression (6–9), indicating that the effects of HLA class I molecules on HIV-1 specific CTL responses play a major role in controlling viremia. A number of studies have reported differential impacts of HLA class

I allele expression on the level of the pVL and/or disease outcome: HLA-B27, B51 and B57 are associated with lower pVL and better clinical outcome (7, 10–12), whereas HLA-B*3502/3503 and B53 have a detrimental effect on these parameters (6, 8, 13, 14). However, such studies have been performed either in Western countries, such as the United States (6, 7, 11), or in South Africa (12), where Caucasians and/or Africans dominate over other ethnic groups; accordingly information from Asian countries is largely lacking, although an estimated Bay 11-7085 5.0 million people were living with HIV/AIDS in Asia in 2007, accounting for 15% of the world total (15). Because people living in Asia have distinct patterns of HLA class I profiles, the known associations between HLA class I allele expression and HIV disease outcome may be applicable only to a limited geographical area on the globe. In order to design globally effective HIV vaccines that aim to induce CTL responses restricted by HLA class I molecules, it is crucial to identify the differential ability of HLA class I alleles to control viremia in different parts of the world. Of importance, CTL escape mutations have been shown to accumulate in populations (16, 17), suggesting that we have been losing targeting epitopes.

[55, 56] The main metabolic pathway for ADMA is citrulline and di

[55, 56] The main metabolic pathway for ADMA is citrulline and dimethylamine or monomethylamine, a reaction catalyzed by DDAH (dimethylarginine-dimethylamino-hydrolase)[57, 58] (Fig. 3). The reaction includes the elimination of the guanidine in ADMA by the cysteine in DDAH. There is no doubt that the cysteine in DDAH is the active component, since its replacement by serine renders

the molecule inactive.[58, 59] Cysteine is susceptible to oxidation and is regulated by NO circulation.[58] Increased NO levels inhibit the DDAH action by S-nitrosylation of the active buy Adriamycin cysteine component. The DDAH inhibition leads to the increase of the ADMA concentration and, therefore, to the inhibition of the NOs (retrograde regulation for the preservation of the ADMA/NO balance).[27]It is not yet clear whether oxidative stress can cause a non-reversible inhibition of the DDAH activity; however, the connection of the nitrosyl group (S-nitrosylation) is indeed reversible[27] (Fig. 4). Dimethylarginine-dimethylamino-hydrolase

is primarily a cytoplasmic enzyme. In humans, two DDAH genes have been identified: on chromosome 1p22 (DDAH-1) and on chromosome 6p21.3 (DDAH-2). For the DDAH-1 gene, eight gene polymorphisms have been identified, while for the DDAH-2 gene, six gene polymorphisms have selleck products been identified.[60, 61] Those two isoenzymes have a different tissue distribution, but share a similar function. Small differences in selective function have been described, for example, DDAH-1 and nNOs, DDAH-2 and eNOs. However, both isomers have a vast distribution in the cardiovascular system[61] and in kidneys,[24] while they are also present in neutrophils and macrophages.[57, 61] The DDAH-1 gene is found to be expressed on endothelial cells from the umbilical veins[24] while three out of eight DDAH-1 polymorphisms were associated with pre-eclampsia and increased plasma ADMA.[62] Increased

levels of ADMA in Rucaparib datasheet CKD are an indication that the kidneys play an important role in its regulation. However, since very small quantities appear in urine, even with normal kidney function,[41, 63-65] it is apparent that the kidneys act as the main elimination pathway for ADMA through its metabolism by DDAH.[24] The proportion of circulating ADMA that is eliminated through renal excretion and through DDAH metabolism seems to vary among different species (e.g. in rats, 90% is metabolized and 10% is excreted through kidneys).[56] In humans, it is estimated that 250–260 μmol are metabolized daily and approximately 50–60 μmol are excreted.[66] For the excretion of this quantity of ADMA, the urine concentrations reach up to 20–30 μmol/L. In the case of a complete inability of ADMA excretion through urine, the plasma concentrations would have to be increased daily by 5 μmol/L.

The detection limits for IFN-γ, IL-10 and IL-13 were 5, 8 and 6 pg/ml, respectively. Identification of proliferating and cytokines secreting cells.  PBMC were first depleted of CD4+ T cells and then of CD8+ T cells using magnetic beads coated with CD4- and CD8-specific monoclonal antibodies (Invitrogen Dynal AS, Oslo, Norway), according to the manufacturer’s instructions. Positively isolated CD4+ and CD8+ cells were detached from beads using Detach-A-Beads

(Invitrogen Dynal AS), and 100,000 pure CD4+ or CD8+ Roscovitine cells were then cultured with the antigen-presenting cells (CD4- and CD8-depleted PBMC) exactly as described for PBMC. Statistical methods.  HBoV- and B19-specific responses were analysed with Wilcoxon signed rank test. The correlations of cytokine with proliferation responses were studied

with Spearman’s correlation. P-values ≤0.05 were considered significant. Human bocavirus–specific proliferation and selleck chemicals llc cytokine responses were readily detectable among the 36 HBoV-seropositive subjects (Fig. 1) using highly purified HBoV-VLP [5]. When HBoV-specific responses were compared with the same subject’s tetanus toxoid (TT) specific ones, stronger proliferation and IL-13 responses were found with TT, whereas IFN-γ and IL-10 responses were statistically similar with these two antigens. B19-specific proliferation responses were significantly stronger than the corresponding HBoV-specific ones (P = 0.028), whereas the cytokine responses were found to be statistically similar: P-values 0.657 with IL-10, 0.910 with IL-13 and 0.286 with IFN-γ (Table 1). Next, we investigated how HBoV- and B19-specific cytokine and proliferation responses correlate among the 20 B19-seropositive subjects (Fig. 2). As shown in Fig. 2,

all HBoV-specific cytokine response pairs showed significant positive correlations (P ≤ 0.002). In particular, HBoV-specific IL-13 responses showed strong correlation with the other HBoV-specific cytokines: P = 0.001 with IL-10 and <0.0001 with IFN-γ. Similar interrelation was found when the correlations of HBoV-specific proliferation and cytokine responses were studied: P = 0.003 (r = 0.627) with IFN-γ, P = 0.033 (r = 0.478) with IL-10 and P ≤ 0.0001 (r = 0.747) with IL-13. Interestingly, although the response patterns appeared to be very similar with B19 and HBoV antigens (Fig. 2), no significant Decitabine purchase correlations could be found between any B19-specific proliferation and cytokine response pairs (P ≥ 0.059). To identify the cell populations accounting for the proliferation responses and secreting the cytokines, we incubated positively selected CD4+ and CD8+ T cells with the antigens. T-cell responses were found almost exclusively among with CD4+ T cells, not with CD8+ cells (Fig. 3). To date, most of the studies on HBoV have been based on PCR or ELISA, while little information on T-cell responses is available [24]. HBoV-VLP are antigens of choice in serodiagnostic assays [5, 20–22] and in in vitro studies of Th-cell immunity [24].

A complete range of motion at the axillary joint was achieved in

A complete range of motion at the axillary joint was achieved in all patients by the end of the reconstruction period. The donor sites were closed primarily with linear scars in all cases. The pre-expanded pedicled TDA perforator flap is a suitable alternative selleck kinase inhibitor for coverage of the axillary defects after the release of the burn contractures. A pliable texture and large size flap can be obtained to transfer to the axillary area and the donor site scar is considered as cosmetically acceptable. © 2010 Wiley-Liss, Inc. Microsurgery,

“The intra-operative latissimus dorsi (LD) pedicle damage during axillary lymph-node dissection by the general surgeon is a rare complication leading to flap failure and poor outcomes. The authors present their experience on this topic and develop a classification of the thoracodorsal (TD) pedicle injuries and reconstruction algorithm. Pedicle damage of LD occurred in five cases, three of which were experienced during immediate breast reconstruction selleck inhibitor and two observed in patients who underwent prior surgery. In two cases the thoracodorsal vein (TDV) was damaged in its proximal segment, thus end-to-end anastomosis was performed

between distal stump of TDV and circumflex scapular vein (CSV). In one case the TDV required simple microsurgical repair while in other two cases the severe damage of vein and artery required more complex surgical strategies in attempt to salvage the flap. Four cases completely survived with one case of rippling phenomenon. One case had partial flap necrosis that required subtotal muscle resection. Based on these cases, the authors have developed a reconstruction algorithm in attempt to repair LD pedicle damage while preserving breast reconstruction. Taking into account its anatomical conformation, TD pedicle injuries are classified in four different types and available options are suggested for all of them according to the anatomical site and to the

mechanism and timing of injury. © 2013 Wiley Periodicals, Inc. Microsurgery 34:5–9, 2014. Autologous tissue transfer is considered the workhorse eltoprazine for reconstruction; it has high success rates and most importantly is related with excellent cosmetic outcomes and great patient satisfaction. Latissimus dorsi (LD) flap is a very reliable, versatile method, and remains one of the best options for many surgeons in breast reconstruction if abdominal tissue is not available.[1-8] The most common complication and the flap’s main disadvantage is the donor-site morbidity with prolonged drainage and seroma risk, but with prudent precautions it is possible to shorten drainage duration and to lower its incidence.[9, 10] The most common causes of intra-operative flap failure are coupled to errors in surgical dissection or excessive tension and torsion of the pedicle, which could lead to flap ischemia and necrosis.

The final diagnoses of the patients were somatoform/conversion di

The final diagnoses of the patients were somatoform/conversion disorder in six, anxiety disorder in four, and depression and other mental illnesses[28] (Table 1). The LUTS in the 16 PUD patients included OAB alone in five, difficult urination alone in one, and both OAB and difficult urination in 10 (Table 2). In most patients, there was a dissociation between LUTS in their daily life and urodynamic findings (Tables 2 and 3) as described below. Lower urinary selleck screening library tract

symptoms often occurred only in particular situations. For example, in one case (case 5), OAB occurred only when the patient was riding on a train with many people standing in the aisle. The psychodynamics underlying these patients may well be reproduced by healthy individuals under stressful conditions in daily life, e.g. a person may need to use the toilet just before starting an important presentation[26] or have difficulty urinating when in close proximity to another person.[26, 31] The severity of such a phenomenon is usually mild and the duration selleckchem is short. However, if an individual feels such symptoms are an extreme bother, he or she may have hypochondria or a phobia involving toileting (mental disorder caused

by toileting); or, if the symptoms are severe and chronic, the individual has PUD (bladder dysfunction caused by mental disorder). Both conditions could occur together. In addition to OAB and difficult urination, two of our patients also showed extremely infrequent voiding (once or twice a day) cases 2, 4 or even an unwillingness to use the toilet. Similar

episodes have been described before.[32] Toileting phobia Rebamipide has been reported to underlie this condition, originating from previous pain in micturition as a result of a urinary tract infection[33] or painful urological investigations.[32] However, no such histories were obtained in our patients. Since there were no urodynamic data available in the depression cohort, we discuss those in PUD patients who visited a urodynamic laboratory because of LUTS. The diagnosis of PUD is basically exclusionary, particularly from urologic, gynecologic, and neurologic causes, and this disorder accompanies more obvious mental features.[29, 34] Within this context, neurologic diseases are not always easy to diagnose, since they may present with LUT dysfunction as the sole initial manifestation, as seen in tethered cord syndrome/spina bifida occulta and multiple system atrophy. In our study, the incidence rate of PUD was 0.7% (16 cases) of 2300 urodynamic cases,[28] after carefully excluding other causes by means of history (with relevant neurologic, urologic, gynecologic, traumatic, or other specific history), neurological examination and, where applicable, electrophysiology, sphincter electromyography (EMG), and magnetic resonance imaging (MRI). The prevalence rate was almost the same as those reported in studies with similar sample sizes, e.g. 2% among 1015 urodynamic cases,[30] 2.
