RESUMO
BACKGROUND: Inflammatory bowel disease (IBD) and psoriasis (Ps) are common immune-mediated diseases that exhibit clinical comorbidity, possibly due to a common genetic structure. However, the exact mechanism remains unknown. METHODS: The study population consisted of IBD and Ps genome-wide association study (GWAS) data. Genetic correlations were first evaluated. Then, the overall evaluation employed LD score regression (LDSC), while the local assessment utilized heritability estimation from summary statistics (HESS). Causality assessment was conducted through two-sample Mendelian randomization (2SMR), and genetic overlap analysis utilized the conditional false discovery rate/conjunctional FDR (cond/conjFDR) method. Finally, LDSC applied to specifically expressed genes (LDSC-SEG) was performed at the tissue level. For IBD and Ps-specific expressed genes, genetic correlation, causality, shared genetics, and trait-specific associated tissues were methodically examined. RESULTS: At the genomic level, both overall and local genetic correlations were found between IBD and Ps. MR analysis indicated a positive causal relationship between Ps and IBD. The conjFDR analysis with a threshold of < 0.01 identified 43 loci shared between IBD and Ps. Subsequent investigations into disease-associated tissues indicated a close association of IBD and Ps with whole blood, lung, spleen, and EBV-transformed lymphocytes. CONCLUSION: The current research offers a novel perspective on the association between IBD and Ps. It contributes to an enhanced comprehension of the genetic structure and mechanisms of comorbidities in both diseases.

Objective: This study aimed to collate all published studies on laser therapy for pilonidal disease and demonstrate the safety and effectiveness of minimally invasive techniques. Methods: A comprehensive literature search, with no language limitations, was performed using PubMed, Embase, and Web of Science from inception to April 23, 2023. Two reviewers independently screened the literature according to the inclusion and exclusion criteria and evaluated the bias risk of included studies. Meta-analysis was performed using RevMan software (version 5.4). (PROSPERO Registration ID Number CRD42023420803). Results: The analysis included 1214 patients from 13 studies, who fulfilled the pre-defined inclusion criteria. With a median follow-up of 12 (range, 7.8-25) months, 1000 (84.4%) patients achieved healing after primary laser treatment. The mean complication and recurrence rates were 12.7% and 7.6%, respectively. Conclusions: Laser ablation for pilonidal sinus disease is a new minimally invasive technique with good treatment efficacy, low postoperative recovery, and shorter recovery periods following employment.
