“In polycystic liver (PLD) and kidney (PKD) diseases, increased cyclic adenosine monophosphate (cAMP) levels trigger hepatorenal cystogenesis. A reduction of the elevated cAMP by targeting somatostatin

receptors (SSTRs) with octreotide (OCT; a somatostatin analog that preferentially binds to SSTR2) inhibits cyst growth. Here we compare the effects of OCT to pasireotide (PAS; a more potent HKI-272 solubility dmso somatostatin analog with broader receptor specificity) on: (1) cAMP levels, cell cycle, proliferation, and cyst expansion in vitro using cholangiocytes derived from control and PCK rats (a model of autosomal recessive PKD [ARPKD]), healthy human beings, and patients with autosomal dominant PKD (ADPKD); and (2) hepatorenal cystogenesis in vivo in PCK rats and Pkd2WS25/- mice (a

model of ADPKD). Expression of SSTRs was assessed in control and cystic cholangiocytes of rodents AZD6244 cost and human beings. Concentrations of insulin-like growth factor 1 (IGF1) and vascular endothelial growth factor (VEGF) (both involved in indirect action of somatostatin analogs), and expression and localization of SSTRs after treatment were evaluated. We found that PAS was more potent (by 30%-45%) than OCT in reducing cAMP and cell proliferation, affecting cell cycle distribution, decreasing growth of cultured cysts in vitro, and inhibiting hepatorenal cystogenesis in vivo in PCK rats and Pkd2WS25/- mice. The levels of IGF1 (but not VEGF) were reduced only in response to PAS. Expression of SSTR1 and SSTR2 (but not SSTR3 and SSTR5) was decreased in cystic cholangiocytes compared to control. Although both OCT and PAS increased the immunoreactivity of SSTR2, only PAS up-regulated SSTR1;

neither drug affected cellular localization of SSTRs. Conclusion: PAS is more effective than OCT in reducing hepatorenal cystogenesis in rodent models; therefore, it might be more beneficial for the treatment of PKD and PLD. (HEPATOLOGY 2013) Polycystic liver (PLD) and kidney (PKD) diseases are genetic disorders linked to disturbances in many intracellular signaling pathways and cell functions.1-3 One of the well-defined mechanisms involved in hepatorenal cystogenesis is increased accumulation of intracellular cyclic adenosine monophosphate (cAMP) that triggers cell hyperproliferation, cell cycle deregulation, and fluid secretion. Basal L-NAME HCl cAMP levels in cholangiocytes are maintained by the coordinated functioning of: (1) secretin receptors (activation of which by secretin increases cAMP); (2) somatostatin receptors ([SSTRs], activation of which by somatostatin inhibits cAMP); (3) adenylyl cyclases (crucial for cAMP production); and (4) phosphodiesterases (critical for cAMP degradation).1, 2 Activation of SSTRs induces multiple transduction pathways and mediates several cellular functions; however, inhibition of cell proliferation is one of the major effects.4, 5 Cholangiocytes express all five SSTRs (i.e., SSTR1 through 5).

34 How MCP-1 modulates oxidative stress pathways or reduces antioxidants PI3K inhibitor will be investigated in the future. Similar up-regulation of microsomal CYP2E135 in alcohol-fed WT and MCP-1KO mice indicate the induction of oxidative stress independent of alcohol-metabolizing CYP2E1. Besides cellular mechanisms, such as TLR expression, oxidative stress contributes to LPS sensitization in ALD and enhancement of pro inflammatory cytokine gene expression.36, 37 An in vivo LPS challenge given at the end of chronic alcohol feeding led to an augmentation of proinflammatory cytokines TNFα, IL-1β, and IL-6 in WT mice, and this was prevented in MCP-1KO mice. Our results suggest that MCP-1 deficiency

inhibits oxidative stress and also impedes sensitization to LPS, independent of TLR4 expression, during alcoholic

liver injury. Studies to unravel the mechanisms of LPS sensitization affected selleck kinase inhibitor by MCP-1 during chronic alcohol exposure will be examined in the future. Among the various mechanistic studies for alcoholic steatosis, alterations in transcription factors, such as PPARα and PPARγ, controlling lipid metabolism have been recognized.24 Previous studies showed that alcohol feeding in rats decreased PPARα activation and downstream target genes important in fatty acid oxidation.19 Here, we show that alcohol-fed MCP-1KO mice exhibit increased PPARα and PPARγ mRNA expression, enhanced nuclear PPARα and PPARγ, PPRE activation in whole liver and isolated hepatocytes, presence

of PPARα/RXRα in the DNA-binding complex, and induction of target genes, such as CPT-1 and ACOX—both enzymes critical in fatty acid oxidation. Previous studies have shown that a secretory product of adipose tissue, likely MCP-1, can induce lipid accumulation in hepatoyctes.13 Our in vitro findings demonstrate that recombinant MCP-1 down-regulates PPARα mRNA expression and DNA-binding activity in hepatocytes, likely contributing to increased triglyceride accumulation in ALD. These results suggest a direct effect of MCP-1 on PPARα and AZD9291 its target genes and thus steatosis. MCP-1 mediates its action via receptor CCR238 or independent of CCR2.39 Our results show that CCR2KO mice induce alcoholic liver injury similar to alcohol-fed WT mice, indicating CCR2-independent effects of MCP-1. Furthermore, because hepatocytes do not express CCR2,18 as reported here (Supporting Fig. 5A), we predict that MCP-1 mediates its effects in the liver independent of CCR2. Another lipid-modulating transcription factor with anti-inflammatory properties, PPARγ, was up-regulated in alcohol-fed MCP-1KO livers. It is likely that PPARγ inhibits proinflammatory cytokine production in chronic alcohol-exposed MCP-1KO mice. Our results here show that MCP-1 expression is directly up-regulated in hepatocytes during chronic alcohol exposure and likely regulates fatty acid oxidation, resulting in steatosis.

Entecavir 0.5 mg daily was prescribed except in G 3 where 1.0 mg was used. Liver biochemistries, selleck inhibitor creatinine, HBV serology, and HBV DNA were monitored every 3-6 months. Hepatocellular

carcinoma surveillance with ultrasound was done every 6 months. Adverse events were captures. Results: There were 709 patients, male 63.2%, mean age of 50.8±1 0.5 years with mean follow up of 61.5±37.2 months, and median of follow up of 63 months (12-108 months). Mean baseline HBV DNA was 5.1 log10 IU/mL and 34.8% HBeAg positive. Patients in G 1, 2, 3, 4 were 535, 123, 17, and 34 patients, respectively. During 5 years of follow up, viral load was undetectable 97.3% in G 1, 97.6% in G 2, 94.1% in G 3, and 95.5% in G 4. Normalization of ALT was observed more than 90% in every G. HBeAg seroconver-sion was found 33.3%, 20.3%, 29.4%, and 30.1% in G 1, 2, 3, and 4, respectively. Eleven patients had

HBsAg loss. Virological breakthrough was found in 6 patients (4, 1, and 1 in G 1, 2 and 3, respectively). However, no virologic resistance was detected. No significant adverse event was observed. Conclusions: This is one of the largest real-world study in a single center which has shown that ETV can effectively and continuously suppress HBV DNA from 94.1 to 97.6% in NUC-naïve, NUC BTK inhibitor experienced, lamivudine or Peg-IFN failure CHB patients for the Interleukin-2 receptor average of more than 5 years. Rate of virological breakthrough was low and the treatment is safe without significant side effects. Disclosures: Tawesak Tanwandee – Grant/Research Support: Bristol-Myers Squibb, Biotron, MSD,

Patients with older age and severe comorbidities are usually excluded from clinical trials. Thus, data from real-life cohorts are needed. The aim of this study was to analyze the 2-year data on the efficacy and tolerance of TDF treatment in a real-life cohort, especially in elderly patients. Methods: 441 HBV patients treated with TDF were included from June 2009 to April 201 0 in a French real-life, multicentre, prospective cohort (VIREAL study). Clinical, serologic and virologic data were collected at baseline and every 6 months. Preliminary analyses after 2 years of treatment were performed in the overall population and a subgroup of elderly patients (>65 years).

Patients were GW-572016 molecular weight divided into NAFLD with CAD (n=54), NAFLD without CAD (n=15), only CAD (n=34) and Non-NAFLD and Non-CAD (n=16). Each angiogram was reviewed centrally for the presence and severity of CAD (number of proximal arterial segments with>70% stenosis). Concentrations of anti-HSP antibodies (anti-HSP27, anti-HSP60 and anti-HSP70) were determined in the serum collected at the time of angiography using ELISA technique. Results: The levels of the serum anti-HSP70 antibodies were higher in NAFLD patients with CAD (median, 30.6 μg/ml) than NAFLD patients without CAD

(median, 26.0 μg/ ml, P=0.04). We also found that the levels of the serum anti-HSP60 antibodies were higher in NAFLD patients with CAD (median, 23.8 μg/ml) than patients with

only CAD (median, 16.6 μg/ml, P=0.04). Furthermore, severity of CAD positively correlated with anti-HSP70 antibodies (r=0.33; P=0.01). In this cohort, levels of serum anti-HSP70 antibodies [OR: 1.08 (95% CI: 1.01-1.16)] and age [OR: 1.11 (95%: 1.03-1.21)] were independently associated with the PLX4032 in vitro risk of having CAD in patients with NAFLD. Levels of anti-HSP27 antibodies were not significantly associated with CAD in NAFLD. Conclusions: In patients with NAFLD, anti-HSP70 auto-antibodies may play a role in the development of CAD by attenuating the cardiopro-tective effect of the HSP70. The ratio of the anti-HSP antibodies to HSP may also have diagnostic value. Disclosures: Brian P. Lam – Advisory Committees or Review Panels: BMS; Speaking and Teaching: Gilead; Stock

Campbell, Thomas Jeffers, Spencer Frost, Bryan Ray-buck, Zobair Younossi Background. Several steatosis biomarkers (SbM) are available with mafosfamide limited independent validation. Aim. To determine the diagnostic value and the limitations of several SbM using liver biopsy as a reference standard in a large cohort of patients with suspected NAFLD. Their performance for the diagnosis and the quantification of steatosis, the confounding effect of fibrosis and inflammation and their relationship to insulin resistance were studied. Methods. 324 consecutive liver biopsies performed for suspected NAFLD were included. Histological steatosis was categorized as none(<5%), mild(5-33%), mod-erate(33-66%) and severe(>66%). Five SbM were measured: fatty liver index (FLI), NAFLD liver fat score (LFS), hepatic steatosis index (HSI), visceral adiposity index (VAI) and tri-glyceride × glucose (TyG) index. Results. The prevalence of steatosis grades was: none 5%, mild 39%, moderate 30% and severe 27%. Except for VAI, the SbM showed a linear trend across the steatosis grades.

19 T cells

among LMCs were separated using a Pan T cell isolation kit II. Non–T cells (B cells, NK cells, DCs, monocytes, granulocytes, and erythroid cells) were indirectly magnetically labeled using a cocktail of biotin-conjugated antibodies against CD14, CD16, CD19, CD36, CD56, CD123, glycophorin A, and anti-biotin microbeads. selleck products Isolation of purified T cells was achieved by depletion of magnetically labeled cells by separation over a MACS column, which was placed in the magnetic field of a MACS Separator; a purity of CD3+ T cells of >90% was confirmed by flow cytometry. Monocytes were separated with a monocyte isolation kit. Non-monocytes were indirectly magnetically labeled with a cocktail of biotin-conjugated monoclonal antibodies against CD3, CD7, CD16, CD19, CD56, CD123, and glycophorin A, and anti-biotin microbeads. Isolation of monocytes was achieved by depletion of magnetically labeled cells; a purity of CD14+ monocytes of >90% was confirmed by way of flow cytometry. NK cells were separated with an NK isolation kit. Non-NK cells were indirectly magnetically labeled with a cocktail of biotin-conjugated antibodies against lineage-specific antigens and anti-biotin microbeads. Isolation of NK cells

was achieved through the depletion of magnetically labeled cells; a purity of CD56+ NK cells of >90% was confirmed by way of flow cytometry. mDCs (CD1c+) were separated with an mDC isolation kit performed by two magnetic separation steps. In the first step, CD1c-expressing B cells were magnetically tuclazepam labeled with CD19 microbeads and subsequently depleted magnetically. Bcl-2 inhibitor In the second step, CD1c+ mDCs in the B cell–depleted flow-through fraction were indirectly magnetically labeled with CD1c-biotin and anti-biotin microbeads. Upon separation, the labeled CD1c+ mDCs were retained within the column and eluted after removing the column from the magnetic field. A purity of CD1c+ CD19− mDCs of >80% was confirmed by way of flow cytometry. NKT cells were separated with an NKT isolation kit. The isolation of NKT cells was performed in two magnetic separation

steps. In the first step, NK cells and monocytes were indirectly magnetically labeled using a cocktail of biotin-conjugated antibodies and anti-biotin microbeads. The labeled cells were subsequently depleted by separation over a MACS Column. In the second step, CD3+CD56+ NKT cells were directly labeled with CD56 microbeads and isolated by positive selection from the pre-enriched NKT cell fraction. Upon separation, the labeled CD56+ cells were retained within the column and eluted after removing the column from the magnetic field. A purity of CD3+ CD56+ NKT cells of >80% was confirmed by flow cytometry. Cell populations (2 × 104/200 μL in 96-well plates) were cultured for 48 hours in the presence of the TLR ligands described above at 10 μg/mL.

Recent advances in imaging have enhanced our understanding of the morphological adaptations of muscle in response to disease and altered use. Adaptation in muscle morphology has been linked to changes in muscle strength. To date, no studies have compared muscle morphology and strength in young children with haemophilia to that of typically developing children. This study PXD101 explored differences in muscle strength and morphology between typically developing and age and size-matched boys aged 6–12 years with haemophilia and a history of recurrent haemorrhage in the ankle joint. Maximum muscle strength of the knee flexors (KF), extensors (KE), ankle dorsi

(ADF) and plantar flexors (APF) was measured in 19 typically developing boys (Group 1) and 19 boys with haemophilia (Group 2). Ultrasound images of vastus lateralis (VL) and lateral gastrocnemius (LG) were recorded to determine muscle cross-sectional area (CSA), thickness, width, fascicle length and pennation angle. Muscle strength of the KE, ADF

and APF were significantly (P < 0.05) lower in Group 2 when compared with Group 1. Muscle CSA and width of VL were significantly smaller and pennation angles significantly larger in Group 2 (P < 0.05). Muscle CSA and thickness of LG were significantly (P < 0.05) smaller in Group 2. Linear regression showed that LG muscle CSA and thickness were significant (P < 0.01) predictors of APF muscle strength. Following ankle joint bleeding Daporinad in young boys with haemophilia, secondary adaptations

in muscle strength and morphology were observed, suggesting that muscle function is more impaired than current clinical evaluations imply. “
“Summary.  Factor V (FV) deficiency is a rare coagulation disorder, characterized by a bleeding phenotype varying from mild to severe. To date, 115 mutations have been described along the gene encoding for FV (F5) but only few of them have been functionally characterized. Aim of this study was the identification and the molecular characterization of genetic defects underlying severe FV deficiency in a 7-month-old next Turkish patient. Mutation detection was performed by sequencing the whole F5 coding region, exon–intron boundaries and about 300 bp of the promoter region. Functional analysis of the identified missense mutation was conducted by transient expression of wild-type and mutant FV recombinant molecules in COS-1 cells. Two novel mutations: a missense (Pro132Arg) and a 1-bp deletion (Ile1890TyrfsX19) were identified in the F5 gene. While the frameshift mutation is responsible for the introduction of a premature stop codon, likely triggering F5 mRNA to nonsense-mediated mRNA degradation, the demonstration of the pathogenic role of the Pro132Arg mutation required an experimental validation.

“Abundant mycolic acids are the hallmark of the mycobacterial cell wall. The biosynthesis of mycolic acids fulfilled by type I (Fas-I) and type II (Fas-II) synthase systems necessitates long chain fatty acids as the raw material. Fas-I is responsible for de novo fatty acid synthesis to form fatty acids 16–24 carbons in length and then elongated by the monofunctional enzymes of Fas-II to form long chain fatty acids, and further to form mycolic acids. Mutation of monofunctional enzymes can confer mycobacterial drug resistance. The key monofunctional enzymes of this system might represent new drug target candidates for antituberculosis drug development. “
“Porphyromonas gingivalis is a Gram-negative oral anaerobe that

is involved in the pathogenesis of periodontitis, an inflammatory disease that destroys the tissues supporting the tooth, eventually leading to tooth loss. Porphyromonas gingivalis has can locally invade periodontal MI-503 chemical structure tissues and evade the host defence mechanisms. In doing so, it utilizes a panel of virulence factors that cause deregulation of the innate immune and inflammatory responses. The present review discusses the invasive and evasive strategies of

P. gingivalis and the role of its major virulence factors in these, namely lipopolysaccharide, capsule, gingipains and fimbriae. Moreover, the role of P. gingivalis as a ‘keystone’ biofilm species in orchestrating a host response, is highlighted. Periodontal disease, or periodontitis, is defined as a bacterially induced inflammatory disease of the tooth-supporting (periodontal) tissues. Although more than 700 bacterial species can colonize the oral cavity (Aas et al., 2005), only a handful of those are highly Nutlin-3 nmr implicated in the disease (Paster et al., 2006). Porphyromonas gingivalis is the species most highly associated with the chronic form of periodontitis, and can be detected in up to 85% of the disease sites (Yang et al., 2004). It is detected rarely or at low in numbers in healthy sites. The presence of P. gingivalis in a periodontal pocket may predict imminent disease progression (van Winkelhoff et al., 2002) and a significant positive correlation is found between P. gingivalis numbers and pocket depth (Kawada et al., 2004). Following periodontal treatment, a reduction of P.

ZL 95 106749.4). This strain is highly toxic to lepidopteran pests owing to the presence of the cry1Aa, cry1Ab, cry1Ac and cry2 toxin genes on plasmids (Sun et al., 2000; Chao et al., 2007). ISs were seldom examined as a whole in the B. cereus group genomes probably because http://www.selleckchem.com/products/bmn-673.html these elements constitute only a very small proportion

in these genomes, in contrast to their burst in the YBT-1520 genome. A detailed characterization of these ISs in YBT-1520 is presented in this work. Moreover, a comparative analysis of their counterparts in 18 published B. cereus group genomes as well as in different B. thuringiensis strains has been carried out in order to understand the evolution and dynamics of these IS elements. The B. thuringiensis strains used in this study were grown in Luria–Bertani medium at 28 °C for 12–15 h, under agitation at 150 r.p.m. The B. thuringiensis standard strains were kindly provided by Dr Daniel R. Zeigler of the Bacillus Genetic Stock Center of Ohio State University. Three YBT-1520 genomic Selleckchem XL184 libraries were prepared. Genomic DNA extraction and BAC library construction were described previously (Zhao et al., 2007). Random clones were sequenced using Megabace 1000 and ABI 3730 automated sequencers. The results were analyzed using abi sequencing analysis software, and assembled using the phred/Phrap/consed package (Ewing et al., 1998; Gordon et al., 1998). All consensus sequences were generated with phred quality >40.

Homology searches were performed using blastn and blastx

(Gordon et al., 1998) at GenBank and ISfinder (Siguier et al., 2006b) to identify the ISs. Positive matches for transposase/integrase were confirmed manually to determine which family they belong to by comparisons of the element size, presence of terminal IRs and direct repeats (DRs), number of ORFs, Tpases Pfam domain (Sonnhammer et al., 1997) and the DDE consensus region with related elements (Mahillon & Chandler, 1998). For each kind of IS element, 300 bases upstream of the Tpases coding region were aligned with the reverse complement of 300 bases downstream of the coding region to confirm the IR sequence. When the IRs were not found, the nucleotide sequences in addition to 500 bases up and downstream of Tpases were aligned using clustalw (Chenna et al., 2003) to confirm the IS region. Fragments with <50% of Exoribonuclease the full length were excluded. Any copies of ISs on plasmids were excluded and only the chromosome was considered. Genome DNA (5 μg) was digested with restriction endonuclease EcoRI or Bst1107I (Fermentas), which had no recognized sites in IS231C, IS232A and ISBth166. DNA samples were separated in a 0.8% agarose gel and transferred onto a nylon N+ membrane (Amersham, Piscataway, NJ) and hybridized with a digoxigenin-labelled probe, according to the procedure of Sambrook & Russell (2001). Three digoxigenin-labelled probes were prepared using the PCR DIG Probe Synthesis Kit (Roche) with the primer sets shown in Table 1.

Here, we explored

the role of biogenic amines acting on the pre-Bötzinger complex (pre-BötC), an area located in the ventrolateral medulla which is critical for the generation of different forms of breathing. Isolated in transverse slices from mice, this region continues to spontaneously generate rhythmic activities that resemble normal (eupneic) inspiratory activity in normoxia and gasping in hypoxia. We refer to these as ‘fictive eupneic’ and ‘fictive gasping’ activity. When exposed to hypoxia, the pre-BötC transitions from a network state relying on calcium-activated nonspecific selleck cation currents (ICAN) and persistent sodium currents (INap) to one that primarily depends on the INap current. Here we show that in inspiratory neurons INap-dependent bursting, blocked by riluzole, but not ICAN-dependent bursting, required endogenously released norepinephrine acting on alpha2-noradrenergic receptors (α2-NR). At the network level, fictive eupneic activity persisted while fictive gasping ceased following the blockade of α2-NR. Blockade of α2-NR eliminated fictive

gasping even in slice preparations as well as in inspiratory island preparations. Blockade of fictive gasping by α2-NR antagonists was prevented by activation of 5-hydroxytryptamine type 2A receptors (5-HT2A). Our data suggest that gasping depends on the converging aminergic activation Veliparib nmr of 5-HT2AR and α2-NR acting on riluzole-sensitive mechanisms that have been shown

to be crucial for gasping. “
“This event-related functional magnetic resonance imaging (fMRI) study was designed in such a manner so as to contribute to the present debate on behavioural and functional transfer effects associated with intensive language training. To address this novel issue, we measured professional simultaneous interpreters and control subjects while they performed a non-verbal auditory discrimination task that primarily relies on attention and categorization Pyruvate dehydrogenase lipoamide kinase isozyme 1 functions. The fMRI results revealed that the discrimination of the target stimuli was associated with differential blood oxygen level-dependent responses in fronto-parietal regions between the two groups, even though in-scanner behavioural results did not show significant group differences. These findings are in line with previous observations showing the contribution of fronto-parietal regions to auditory attention and categorization functions. Our results imply that language training modulates brain activity in regions involved in the top-down regulation of auditory functions. “
“Muscle fatigue is defined as an exercise-induced reduction in the force-generating capacity of muscle. Here, we investigated the effect of muscle fatigue on hand dexterity. Healthy adults (n = 17) gripped and lifted an object (0.342 kg) five times before and after two interventions.

All studies were reviewed regardless of effect measure, study design and publication language. Studies on combinations of polysaccharide and conjugate vaccines were excluded. We searched online databases (PubMed, EMBASE and the Cochrane Library) using the following search line: HIV AND vaccine AND (pneumococcal OR pneumonia OR pneumoniae). Reference lists of studies found in the initial search were examined for studies that had not been previously identified. The outcome of interest see more was the vaccine effectiveness in preventing any of three pre-specified clinical

endpoints: all-cause pneumonia, all-pneumococcal disease and IPD. Thus, all studies that reported at least one of these endpoints for HIV-infected individuals who had or had not received PPV-23 were included. The search was conducted independently by two reviewers (RHP and OSS) and data were extracted in duplicate from 1 June 2009 to 1 March 2010. Varying definitions were accepted for the diagnosis of pneumonia (e.g. physician-diagnosed or X-ray-confirmed). For infection with S. pneumoniae and IPD there had to be a positive culture of S. pneumoniae, and for IPD the

specimen had to originate from a normally sterile site (any sterile site was accepted). Risk estimates from each study were recorded, along with other important study details (including study design, setting, statistical models used to control for potential confounding factors, baseline characteristics of study participants and study limitations). Selumetinib molecular weight For each study, the extent of confounders controlled for was tabulated and risk estimates were stratified according to clinical endpoints. Plots of vaccine effectiveness

were produced for all clinical endpoints. Further, we stratified study subjects as controls vs. cases in case–control studies, and as vaccinated vs. unvaccinated Tacrolimus (FK506) in other study types and tabulated major risk factors for pneumococcal infection (treatment, race, smoking and CD4 cell count) to look for trends in the risk estimates. In one instance, the same study was described in two publications [14,35]. Both publications were examined in order to retrieve maximal information. In another instance, the risk estimate was published without a confidence interval, which had to be calculated from the P-value [36]. We included one randomized trial and 15 observational studies in our review. The randomized trial had data on the three outcomes of interest. Seven observational studies reported data on all-cause pneumonia, six on S. pneumoniae infection and six on IPD. This randomized, double-blind, placebo-controlled trial took place in Uganda from 1995 to 1998 and initial results were published in 2000 [14]. A subsequent report included an additional 3 years of follow-up and was published in 2004 [35]. The trial was conducted among 1323 Ugandan adults not receiving HAART. Participants were randomized 1:1 to immunization with a single dose of PPV-23 or placebo inoculation (buffered sodium phosphate).
