Change in N-terminal prohormone of brain natriuretic peptide did not predict clinical response.

Emerging evidence highlights the role of microRNAs (miRNAs) in pulmonary hypertension, though findings on miRNA expression in CTEPH remain limited and inconsistent. This systematic review evaluates miRNA expression changes in CTEPH and their direction. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we registered our protocol in International Prospective Register of Systematic Reviews (CRD42024524469). We included studies on miRNA expression in CTEPH with comparative or analytical designs, excluding nonhuman studies, interventions, non-English texts, conference abstracts, and editorials. Databases searched included PubMed, EMBASE, Scopus, CENTRAL, and ProQuest. The Quality Assessment of Diagnostic Accuracy Studies-2 tool assessed bias risk, and results were synthesized narratively. Of 313 unique studies, 39 full texts were reviewed, and 9 met inclusion criteria, totaling 235 participants. Blood samples were analysed using quantitative real time polymerase chain reaction. Seven miRNAs (miR-665, miR-3202, miR-382, miR-127, miR-664, miR-376c, miR-30) were uniformly upregulated, while nine (miR-20a-5p13, miR-17-5p, miR-93-5p, miR-22, let-7b, miR-106b-5p, miR-3148, miR-320-a, miR-320b) were downregulated in CTEPH patients. Two upregulated miRNAs (miR-127 and miR-30a) were consistently associated with previous evidence in the mechanism inducing the development of CTEPH, and five downregulated miRNAs (miR-20-a, miR-17-5p, miR-93-5p, let-7b, miR-106b-5p) were associated with a protective effect against CTEPH. We also identified gaps in the literature where the evidence for five upregulated miRNAs (miR-665, miR-3202, miR-382, miR-664 and miR-376c) and four downregulated miRNAs (miR-22, miR-3148, miR-320-a, and miR-320b) in CTEPH is conflicting.

TB is rarely listed as a cause of pulmonary hypertension (PH) in most PH guidelines, yet PH may develop at various stages in the time course of TB, from active infection through to the post-TB period. Predisposing risk factors for the development of PH are likely multifactorial, involving active TB disease and post-TB lung disease (PTLD), host-related and environment-related factors. Moreover, post-TB PH should likely be classified in Group 3 PH, with the pathogenesis similarly complex and multifactorial as other Group 3 PH causes. Identifying risk factors that predispose to post-TB PH may aid in developing risk stratification criteria for early identification and referral for confirmatory diagnostic tests. Given that universal screening for PH in TB survivors may be impractical and unfeasible, a targeted screening approach for high-risk individuals would be sensible. In this scoping review of post-TB PH, resulting from the proceedings of the 2nd International Post-Tuberculosis Symposium, we aim to describe the epidemiology, risk factors, and pathophysiology of post-TB PH. We emphasize diagnosing PH with an alternative set of diagnostic guidelines in resource-constrained settings where right heart catheterization may not be feasible. Research to describe the burden and distribution of post-TB PH should be prioritized as there is a current gap in knowledge regarding the prevalence and incidence of post-TB PH among persons with TB.","PeriodicalId":20927,"journal":{"name":"Pulmonary Circulation","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142256013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
