RESUMO

BACKGROUND: The use of complementary and alternative medicines is increasing among chronic patients, particularly those afflicted with inflammatory bowel diseases. AIM: This study aimed to address the prevalence of complementary and alternative medicines use among Portuguese inflammatory bowel diseases' patients. METHODS: Patients were invited to fill an anonymous questionnaire concerning the use of complementary and alternative medicines. RESULTS: Thirty-one per cent of the patients reported having used complementary and alternative medicines in the past, whereas 12% were using them by the time the questionnaire was administered. Fifty-nine per cent of the users did not share this information with their physician, whereas 14% and 8% discontinued their medication and periodical examination, respectively. Steroids prescription (OR=2.880) and a higher instruction level (OR=3.669) were predictors of complementary and alternative medicines use in this cohort. CONCLUSIONS: Roughly a third of Portuguese IBD patients had used CAM. Steroid treatment and an academic degree are associated with CAM use. Given the potential side effects and interactions, patient information about the benefits and limitations of conventional and complementary treatments should be reinforced.

RESUMO

Foot-and-mouth disease virus (FMDV) causes a highly contagious disease of cloven-hoofed animals. We have previously demonstrated that a replication-defective human adenovirus 5 vector carrying the FMDV capsid coding region of serotype A24 Cruzeiro (Ad5-CI-A24-2B) protects swine and cattle against FMDV challenge by 7 days post-vaccination. However, since relatively large amounts of Ad5-CI-A24-2B are required to induce protection this strategy could be costly for livestock production. Poly ICLC is a synthetic double stranded RNA that activates multiple innate and adaptive immune pathways. In this study, we have tested for the first time, the adjuvant effect of poly ICLC in combination with Ad5-CI-A24-2B in swine. We found that the combination resulted in a reduction of the vaccine protective dose by 80-fold. Interestingly, the lowest dose of Ad5-CI-A24-2B plus 1mg of poly ICLC protected animals against challenge even in the absence of detectable FMDV-specific neutralizing antibodies at the time of challenge.

RESUMO

In recent years, we have developed novel strategies to control foot-and-mouth disease (FMD), including the use of biotherapeutics such as interferons (IFN) delivered by a replication-defective human adenovirus type 5 (Ad5). Swine can be sterilely protected after vaccination with an Ad5 that encodes porcine type I IFN (poIFN-α), and cattle can be similarly protected or develop significantly reduced disease when treated with an Ad5 delivering bovine type III IFN (boIFN-λ3). Here, we have evaluated the efficacy of porcine IFN-λ3 (poIFN-λ3) against FMD virus in vivo. Swine inoculated with different doses of Ad5-poIFN-λ3 were protected against disease in a dose-dependent manner. Despite the absence of systemic antiviral activity, 7 out of 10 Ad5-poIFN-λ3 inoculated animals did not develop disease or viremia, and the other 3 inoculated animals displayed delayed and milder disease by 7 days postchallenge as compared with control animals inoculated with an Ad5 control vector. While analysis of gene expression showed significant induction of IFN and IFN-stimulated genes in Ad5-poIFN-λ3-treated cultured porcine epithelial kidney cells, there was limited gene induction in peripheral blood monocytes isolated from treated swine. These results suggest that treatment with Ad5-poIFN-λ3 is an effective biotherapeutic strategy against FMD in swine.

RESUMO

We have previously shown that delivery of the porcine type I interferon gene (poIFN-α/ß) with a replication-defective human adenovirus vector (adenovirus 5 [Ad5]) can sterilely protect swine challenged with foot-and-mouth disease virus (FMDV) 1 day later. However, the need of relatively high doses of Ad5 limits the applicability of such a control strategy in the livestock industry. Venezuelan equine encephalitis virus (VEE) empty replicon particles (VRPs) can induce rapid protection of mice against either homologous or, in some cases, heterologous virus challenge. As an alternative approach to induce rapid protection against FMDV, we have examined the ability of VRPs containing either the gene for green fluorescent protein (VRP-GFP) or poIFN-α (VRP-poIFN-α) to block FMDV replication in vitro and in vivo. Pretreatment of swine or bovine cell lines with either VRP significantly inhibited subsequent infection with FMDV as early as 6 h after treatment and for at least 120 h posttreatment. Furthermore, mice pretreated with either 10(7) or 10(8) infectious units of VRP-GFP and challenged with a lethal dose of FMDV 24 h later were protected from death. Protection was induced as early as 6 h after treatment and lasted for at least 48 h and correlated with induction of an antiviral response and production of IFN-α. By 6 h after treatment several genes were upregulated, and the number of genes and the level of induction increased at 24 h. Finally, we demonstrated that the chemokine IP-10, which is induced by IFN-α and VRP-GFP, is directly involved in protection against FMDV.

RESUMO

Foot-and-mouth disease virus (FMDV) is a highly contagious pathogen that causes severe morbidity and economic losses to the livestock industry in many countries. The oral and respiratory mucosae are the main ports of entry of FMDV, so the stimulation of local immunity in these tissues may help prevent initial infection and viral spread. E. coli heat-labile enterotoxin (LT) has been described as one of the few molecules that have adjuvant activity at mucosal surfaces. The objective of this study was to evaluate the efficacy of replication-defective adenovirus 5 (Ad5) vectors encoding either of two LT-based mucosal adjuvants, LTB or LTR72. These vectored adjuvants were delivered intranasally to mice concurrent with an Ad5-FMDV vaccine (Ad5-A24) to assess their ability to augment mucosal and systemic humoral immune responses to Ad5-A24 and protection against FMDV. Mice receiving Ad5-A24 plus Ad5-LTR72 had higher levels of mucosal and systemic neutralizing antibodies than those receiving Ad5-A24 alone or Ad5-A24 plus Ad5-LTB. The vaccine plus Ad5-LTR72 group also demonstrated 100% survival after intradermal challenge with a lethal dose of homologous FMDV serotype A24. These results suggest that Ad5-LTR72 could be used as an important tool to enhance mucosal and systemic immunity against FMDV and potentially other pathogens with a common route of entry.

RESUMO

Foot-and-mouth disease virus (FMDV) causes a highly contagious disease of cloven-hoofed animals. Vaccines require ∼7 days to induce protection; thus, before this time, vaccinated animals are still susceptible to the disease. Our group has previously shown that swine inoculated with 1×10(11) focus forming units (FFU) of a replication-defective human adenovirus containing the gene for porcine interferon alpha (Adt-pIFN-α) are sterilely protected from FMDV serotypes A24, O1 Manisa, or Asia 1 when the animals are challenged 1 day postadministration, and protection can last for 3-5 days. Polyriboinosinic-polyribocytidylic acid stabilized with poly-l-lysine and carboxymethyl cellulose (poly ICLC) is a synthetic double-stranded RNA that is a viral mimic and activates multiple innate immune pathways through interaction with toll-like receptor 3 and MDA-5. It is a potent inducer of IFNs. In this study, we initially examined the effect of poly IC and IFN-α on FMDV replication and gene induction in cell culture. Poly ICLC alone or combined with Adt-pIFN-α was then evaluated for its therapeutic efficacy in swine against intradermal challenge with FMDV A24, 1 day post-treatment. Groups of swine were subcutaneously inoculated either with poly ICLC alone (4 or 8 mg) or in combination with different doses of Adt-pIFN-α (2.5×10(9), 1×10(9), or 2.5×10(8) FFU). While different degrees of protection were achieved in all the treated animals, a dose of 8 mg of poly ICLC alone or combined with 1×10(9) FFU of Adt-pIFN-α was sufficient to sterilely protect swine when challenged 24 h later with FMDV A24. IFN-stimulated gene (ISG) expression in peripheral blood mononuclear cells at 1 day post-treatment was broader and higher in protected animals than in nonprotected animals. These data indicate that poly ICLC is a potent stimulator of IFN and ISGs in swine and at an adequate dose is sufficient to induce complete protection against FMD.

RESUMO

Foot-and-mouth disease virus (FMDV) leader proteinase (L(pro)) cleaves itself from the viral polyprotein and cleaves the translation initiation factor eIF4G. As a result, host cell translation is inhibited, affecting the host innate immune response. We have demonstrated that L(pro) is also associated with degradation of nuclear factor κB (NF-κB), a process that requires L(pro) nuclear localization. Additionally, we reported that disruption of a conserved protein domain within the L(pro) coding sequence, SAP mutation, prevented L(pro) nuclear retention and degradation of NF-κB, resulting in in vitro attenuation. Here we report that inoculation of swine with this SAP-mutant virus does not cause clinical signs of disease, viremia, or virus shedding even when inoculated at doses 100-fold higher than those required to cause disease with wild-type (WT) virus. Remarkably, SAP-mutant virus-inoculated animals developed a strong neutralizing antibody response and were completely protected against challenge with WT FMDV as early as 2 days postinoculation and for at least 21 days postinoculation. Early protection correlated with a distinct pattern in the serum levels of proinflammatory cytokines in comparison to the levels detected in animals inoculated with WT FMDV that developed disease. In addition, animals inoculated with the FMDV SAP mutant displayed a memory T cell response that resembled infection with WT virus. Our results suggest that L(pro) plays a pivotal role in modulating several pathways of the immune response. Furthermore, manipulation of the L(pro) coding region may serve as a viable strategy to derive live attenuated strains with potential for development as effective vaccines against foot-and-mouth disease.

RESUMO

We previously demonstrated that an adenovirus-based foot-and-mouth disease virus (FMDV) serotype A24 capsid subunit vaccine, Ad5-A24, expressed under the control of a cytomegalovirus promoter (CMV) can protect swine and bovines against homologous challenge, but in a similar approach using swine vaccinated with an Ad5-vectored FMDV O1 Campos vaccine, Ad5-O1C, the animals were only partially protected when challenged at 21 days post-vaccination (dpv). Recently, we demonstrated that inclusion of the complete coding region of nonstructural protein 2B in the Ad5-A24 vector resulted in improved immune responses in pigs. We also found that inclusion of a modified CMV promoter (pCI), Ad5-CI-A24-2B, enhanced the efficacy of the vector. To address the limited immunogenicity of Ad5-O1C, we have produced a new set of Ad5 vectors with the complete 2B coding region under the control of either the original or the modified version of the CMV promoter, Ad5-O1C-2B, or Ad5-CI-O1C-2B, respectively. To evaluate the potency and efficacy of the new vectors we performed 2 sets of experiments in cattle. In the first experiment we compared the original vector with vectors containing the pCI promoter and partial or full-length 2B. All groups were challenged, intradermally in the tongue, at 21 dpv with FMDV O1C. We found that in all vaccinated groups 2 of 4 animals were protected from clinical disease. In the second experiment we directly compared the efficacy of vectors with a partial or full-length 2B under the control of the original CMV promoter. While all animals in the control group developed clinical disease, 2 of 4 animals in the group receiving Ad5-O1C vaccine and 3 of 4 animals in the group receiving Ad5-O1C-2B vaccine were completely protected after challenge. We also observed a 100-fold reduction of virus shedding in Ad5-O1C vaccinated animals and the group receiving Ad5-O1C-2B had an additional 10-fold reduction compared with the Ad5-O1C vaccinated group. There was no difference in the level of neutralizing antibodies in the vaccinated groups. However, we detected a significant antigen specific-CD4(+) and CD8(+) T cell response as early as 1 day post-challenge (dpc) in both Ad5-O1C and Ad5-O1C-2B groups. Interestingly, the group receiving Ad5-O1C-2B had a statistically significant higher antigen specific-CD4(+) and CD8(+) T cell response at 5 dpc and 3 and 5 dpc, respectively, as compared to the Ad5-O1C inoculated group. These results indicate that inclusion of the complete 2B coding region improves the efficacy of Ad5 vaccines against FMDV serotype O and induces specific-CD4(+) and CD8(+) T cell responses that correlate with protection.

RESUMO

Foot-and-mouth disease virus (FMDV) causes a highly contagious disease of cloven-hoofed animals. Current inactivated vaccines require approximately 7 days to induce protection, but before this time vaccinated animals remain susceptible to disease. Previously, we demonstrated that intramuscular (IM) inoculation of a replication-defective human adenovirus type 5 (Ad5) vector containing a porcine interferon α gene (pIFNα) can protect swine challenged 1 day later by intradermal (ID) injection with FMDV A24 Cruzeiro from both clinical disease and virus replication. To extend these studies to other FMDV serotypes, we demonstrated the effectiveness of Ad5-pIFNα against ID challenge with O1 Manisa and Asia-1 and against A24 Cruzeiro in a direct contact challenge model. We also showed that an Ad5 vector containing the pIFNß gene can protect swine against ID challenge with A24 Cruzeiro. Further, IM inoculation of a 10-fold lower dose of Ad5-pIFNα at 4 sites in the neck compared with 1 site in the hind limb can protect swine against ID challenge. These studies demonstrate the ability of Ad5-delivered type I IFN to rapidly protect swine against several FMDV serotypes and suggest that various modifications of this approach may enable this strategy to be successfully used in other FMD susceptible species.

RESUMO

Previously, we demonstrated that type I interferon (IFN-alpha/beta) or a combination of IFN-alpha/beta and type II IFN (IFN-gamma) delivered by a replication-defective human adenovirus 5 (Ad5) vector protected swine when challenged 1 day later with foot-and-mouth disease virus (FMDV). To gain a more comprehensive understanding of the mechanism of protection induced by IFNs, we inoculated groups of six swine with Ad5-vectors containing these genes, challenged 1 day later and euthanized 2 animals from each group prior to (1 day postinoculation [dpi]) and at 1 (2 dpi) and 6 days postchallenge (7 dpi). Blood, skin, and lymphoid tissues were examined for IFN-stimulated gene (ISG) induction and infiltration by innate immune cells. All IFN-inoculated animals had delayed and decreased clinical signs and viremia compared to the controls, and one animal in the IFN-alpha treated group did not develop disease. At 1 and 2 dpi the groups inoculated with the IFNs had increased numbers of dendritic cells and natural killer cells in the skin and lymph nodes, respectively, as well as increased levels of several ISGs compared to the controls. In particular, all tissues examined from IFN-treated groups had significant upregulation of the chemokine 10-kDa IFN-gamma-inducible protein 10, and preferential upregulation of 2',5'-oligoadenylate synthetase, Mx1, and indoleamine 2,3-dioxygenase. There was also upregulation of monocyte chemotactic protein 1 and macrophage inflammatory protein 3alpha in the skin. These data suggest that there is a complex interplay between IFN-induced immunomodulatory and antiviral activities in protection of swine against FMDV.

RESUMO

The leader proteinase (L(pro)) of foot-and-mouth disease virus (FMDV) is involved in antagonizing the innate immune response by blocking the expression of interferon (IFN) and by reducing the immediate-early induction of IFN-beta mRNA and IFN-stimulated genes. In addition to its role in shutting off cap-dependent host mRNA translation, L(pro) is associated with the degradation of the p65/RelA subunit of nuclear factor kappaB (NF-kappaB). Bioinformatics analysis suggests that L(pro) contains a SAP (for SAF-A/B, Acinus, and PIAS) domain, a protein structure associated in some cases with the nuclear retention of molecules involved in transcriptional control. We have introduced a single or a double mutation in conserved amino acid residues contained within this domain of L(pro). Although three stable mutant viruses were obtained, only the double mutant displayed an attenuated phenotype in cell culture. Indirect immunofluorescence analysis showed that L(pro) subcellular distribution is altered in cells infected with the double mutant virus. Interestingly, nuclear p65/RelA staining disappeared from wild-type (WT) FMDV-infected cells but not from double mutant virus-infected cells. Consistent with these results, NF-kappaB-dependent transcription was not inhibited in cells infected with double mutant virus in contrast to cells infected with WT virus. However, degradation of the translation initiation factor eIF-4G was very similar for both the WT and the double mutant viruses. Since L(pro) catalytic activity was demonstrated to be a requirement for p65/RelA degradation, our results indicate that mutation of the SAP domain reveals a novel separation-of-function activity for FMDV L(pro).
