Our aim was to carry out a qualitative and quantitative synthesis of the influence of CCR5 genetic variants on Chagas disease (CD) through a systematic review. A total of 1197 articles were analyzed, and eleven were included in the review. A meta-analysis was conducted along with principal component analyses (PCAs).

Article Synopsis
  • * A systematic review was conducted on 28 articles revealing a limited number of studies focusing on specific genetic polymorphisms linked to SARS, primarily from research conducted in China.
  • * The authors emphasize the need for additional research to better understand the relationship between genetic variations and coronavirus infections, suggesting that existing literature is currently insufficient, particularly in relation to COVID-19.

: Chikungunya virus (CHIKV) is a global concern, inducing chikungunya fever and trigging an arthritogenic chronic phase beyond some severe forms. Outcomes of CHIKV infections in humans are dependent on genetic variations. Here, a systematic review was performed to show evidence of genetic variations on infection outcomes of patients.

Serotonin and nitric oxide seem to be involved in Dengue virus infection. The aim of this study was to investigate if SNPs in serotonin and nitric oxide are associated with dengue severity. A retrospective case-control study was conducted, with groups of dengue fever (DF; n = 78) and dengue hemorrhagic fever patients (DHF; n = 49).

Objective: To evaluate gene polymorphisms and their association with susceptibility to dengue.

Methods: A retrospective case-control study was performed with 262 subjects, comprising 78 dengue fever (DF) patients, 49 dengue hemorrhagic fever (DHF) patients and 135 healthy controls. Genotypic and allelic profiles were identified using polymerase chain reaction based in real time and amplification-refractory mutation system.

Objective: This study determined whether tumor necrosis factor alpha (TNF-α) and Interleukin-10 (IL-10) polymorphisms are associated with susceptibility to dengue.

Methods: a systematic review with meta-analysis was conducted of the associations between the TNF-α (-308G/A) and IL-10 (-819C/T) polymorphisms and dengue.

Results: A total of eight case-controls studies involving 384 individuals with symptomatic dengue, 571 individuals with dengue hemorrhagic fever, and 995 healthy controls were considered in the meta-analysis.
