AB  - Introduction
This study aimed to perform a more precise estimation of the association between tumor necrosis factor-alpha (TNF-α) – 308 G/A single nucleotide polymorphism (SNP) and the risk of development of AP and its phenotypes based on all available published studies.
Methods
The study was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and is registered in PROSPERO (CRD42020176190). The literature search was conducted via: Clarivate Analytics’ Scopus, PubMed, Cochrane Central Register of Controlled Trials and China National Knowledge Infrastructure databases, from inception to December 2020 with no language restrictions. Two reviewers were involved independently in study selection, data extraction and appraising the studies that were included. The quality of included studies was evaluated using the Strengthening the Reporting of Genetic Association (STREGA) and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Frequencies of genotypes and alleles of TNF-alpha (G>A 308, rs1800629) gene, with 95% Odds ratio was used.
Results
Four studies met the inclusion criteria with moderate risk of bias. This study revealed no significant association between TNF-α – 308 G/A SNP and AP, and the risk of AP development. Moreover, there was no significant association between genotype or allele frequency distribution and clinical manifestations (acute versus chronic) of AP. The certainty of evidence per GRADE was very low.
Conclusions
Due to very low certainty of evidence, whether there is an association between TNF-α – 308 G/A SNP and AP, warrants further well-designed multi-centric studies to adjudicate a better understanding of the role of genetic factors in the etiopathogenesis of AP.
