Effectiveness and safety of first-generation protease inhibitors in real-world patients with hepatitis C virus genotype 1 infection in Brazil: a multicenter study

OBJECTIVE: To evaluate the effectiveness and safety of first-generation protease inhibitors for the treatment of genotype 1 hepatitis C virus-infected patients at Brazilian reference centers. METHODS: This multicenter cross-sectional study included hepatitis C virus genotype 1 monoinfected patients treated with Peg-interferon, ribavirin, and either boceprevir (n=158) or telaprevir (n=557) between July 2013 and April 2014 at 15 reference centers in Brazil. Demographic, clinical, virological, and adverse events data were collected during treatment and follow-up. RESULTS: Of the 715 patients, 59% had cirrhosis and 67.1% were treatment-experienced. Based on intention-to-treat analysis, the overall sustained viral response was 56.6%, with similar effectiveness in both groups (51.9% for boceprevir and 58% for telaprevir, p=0.190). Serious adverse events occurred in 44.2% of patients, and six deaths (0.8%) were recorded. Cirrhotic patients had lower sustained viral response rates than non-cirrhotic patients (46.9% vs. 70.6%, p 465 years, diagnosis of cirrhosis, and abnormal hemoglobin levels/platelet counts prior to treatment were associated with serious adverse events. CONCLUSION: Although serious adverse events rates were higher in this infected population, sustained viral response rates were similar to those reported for other patient cohorts.Univ Sao Paulo, Fac Med, Dept Molestias Infecciosas & Parasitarias, Sao Paulo, SP, BrazilUniv Fed Rio de Janeiro, Rio De Janeiro, RJ, BrazilCtr Referencia & Treinamento DST Aids, Sao Paulo, SP, BrazilCDH, Rio De Janeiro, RJ, BrazilHosp Fed Servidores Estado Rio de Janeiro HFSE, Setor Gastrohepatol, Rio De Janeiro, RJ, BrazilUniv Sao Paulo, Fac Med, Dept Gastroenterol & Hepatol, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Disciplina Gastroenterol, EPM, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, EPM, Disciplina Infectol, Sao Paulo, SP, BrazilUniv Sao Paulo, FMRP, Dept Clin Med, Div Gastroenterol, Sao Paulo, SP, Brazil| Univ Fed do Maranhao UFMA, HUPD, Ctr Pesquisa Clin, Sao Luis, MA, BrazilUniv Fed Estado Rio de Janeiro UNIRIO, Disciplina Clin Med & Gastroenterol, Rio De Janeiro, RJ, BrazilUniv Fed Rio do Grande Sul UFRGS, Dept Med Interna, Porto Alegre, RS, BrazilUniv Fed Espirito Santo, Ambulatorio HIV AIDS Hepatites Virais, Vitoria, ES, BrazilSMS, Ctr Orientacao & Aconselhamento, Foz Do Iguacu, PR, BrazilUniv Estado Rio de Janeiro UERJ, Serv Gastroenterol, Rio De Janeiro, RJ, BrazilIMT, Lab Virol LIM 52, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Disciplina Gastroenterol, EPM, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, EPM, Disciplina Infectol, Sao Paulo, SP, BrazilWeb of Scienc

In planta RNAi targeting Meloidogyne incognita Minc16803 gene perturbs nematode parasitism and reduces plant susceptibility.

Meloidogyne incognita is one of the most important plant-parasitic nematodes (PPNs) causing severe crop losses worldwide. Plants have evolved complex defense mechanisms to respond to PPNs attacks. Conversely, PPNs have evolved infection mechanisms that involve the secretion of effector proteins into host plants to suppress immune responses and facilitate para- sitism. Therefore, effector genes are attractive targets for the genetic improvement of plant resistance to M. incognita. In this study, we functionally characterized the Minc16803 (Minc3s00746g16803) putative effector gene to evaluate its role during plant-nematode interactions. First, we found that the Minc16803 gene is expressed in all nematode life stages and encodes a protein with an N-terminal signal peptide for secretion, a motif characteristic of effector proteins and with the absence of transmembrane domain. In addition, our data demonstrated that transgenic Arabidopsis thaliana lines overexpressing a Minc16803-dsRNA efficiently downregulated the Minc16803 transcripts in infecting nematodes. Furthermore, transgenic lines were significantly less susceptible to M. incognita compared to wild-type control plants. The number of galls per plant was reduced by up to 84%, while the number of egg masses per plant decreased by up to 93.3%. Moreover, galls and feed- ing sites in the roots of transgenic lines were smaller than those in the control plants. Histological analysis revealed giant cells without cytoplasm, disordered neighboring cells, and malformed maturing nematodes in transgenic galls. Curiously, numerous hatching ppJ2 juveniles were often observed near the female body within the transgenic root tissues before egg mass extrusion. All findings strongly suggest that Minc16803 gene is a promising target to engineer agricultural crops for M. incognita resistance through host-induced gene silencing.On-line first.
