RESUMO
Dengue is the most prevalent arthropod-borne viral illness in humans worldwide. Single-nucleotide polymorphisms (SNPs) in genes involved in the immune response, such as dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN), IgG Fc receptor II-A (FcγRIIa), vitamin D receptor (VDR), and tumor necrosis factor alpha (TNF-α), were previously reported to be associated with susceptibility to dengue disease in different human populations. Therefore, due to the relevant association of host immune and genetic status with disease susceptibility/severity of dengue, this work aims to verify the frequency of anti-dengue virus antibodies and some dengue-associated risk SNPs in a population in Minas Gerais State, Southeast Brazil. A total of 1560 individuals were genotyped for polymorphisms in DC-SIGN (rs4804803), FcγRIIa (rs1801274), VDR (rs7975232), and TNF-α (rs1800629). The presence of anti-dengue antibodies (IgM and/or IgG) in these samples was also assayed. Anti-dengue antibodies were detected at an overall frequency of 16.86%, indicating a virus infection in asymptomatic individuals. The genotypic frequencies of all SNPs studied did not differ between the asymptomatic and control groups. Regarding the allelic frequencies of the four SNPs analyzed, a higher frequency was detected of the G allele of FcγRIIa/rs1801274 in the asymptomatic individuals when compared to that in the control group (p = 0.03). Therefore, the results showed a high prevalence of asymptomatic individuals in Minas Gerais State, with a potential association between the presence of the G allele of FcγRIIa/rs1801274 and protection against symptomatic disease.

Resumo Objetivo: Avaliar a variação temporal e a correlação entre o bem-estar espiritual e coping religioso/espiritual de pessoas com insuficiência renal crônica em tratamento hemodialítico. Metodologia: Estudo descritivo, analítico e longitudinal. A amostra inicial contou com 118 participantes com perda de 31 ao final das coletas, o que reduziu a amostra final para 87 participantes. Foram aplicados, por meio de entrevista, o questionário sociodemográfico e clínico, a Escala de Coping Religioso/Espiritual Breve (CRE-Breve) e a Escala de Bem-estar Espiritual (EBE) em três coletas distintas, realizadas a cada dois meses. Resultados: Verificou-se que as pessoas com insuficiência renal crônica em hemodiálise fazem uso do enfrentamento religioso e espiritual. A média do CRE positivo foi 3,34, que reflete um escore alto. O EBE total e o EBE religioso associaram-se significativamente à importância dada à religião/espiritualidade (p < 0,001). Conclusão: Os pacientes com insuficiência renal crônica em tratamento hemodialítico entrevistados neste estudo utilizam o coping religioso/espiritual de forma positiva e significativa, da mesma forma que consideram importante a religião/espiritualidade em suas vidas.

Abstract Objective: To assess temporal variation and correlation between spiritual well-being and spiritual/religious coping in people with chronic kidney disease on hemodialysis. Methodology: Longitudinal, descriptive and analytical study. Initial sample was composed of 118 participants, but at the end of data collection, there was a loss of 31 participants, which is why the sample was reduced to 87. A socio-demographic and clinical questionnaire, the Brief Spiritual/ Religious Coping Scale (Brief-SRCOPE Scale), and The Spiritual Well-Being Scale (SWB) were applied using interviews. Data collection were carried out in three stages, at two-month frequent intervals. Results: It was found that people with chronic kidney disease on hemodialysis tend to resort spiritual and religious coping. The spiritual/religious coping mean positive was 3.34, reflecting a high score. On the other hand, total SWB and the religious SWB were significantly associated with the importance given to spirituality/religion (p < 0.001). Conclusions: Patients with chronic kidney disease on hemodialysis make use of spiritual/religious coping positively and significantly; likewise, they regard religion/spirituality as important in their lives.
