Abstract
LONDONO-MORA, Jenny Leandra; LEAL-VARGAS, Drixie Dalyla and QUINTANA-LOPEZ, Gerardo. Prognostic value of capillaroscopy in organ involvement and identification of subtypes in systemic sclerosis (SS): A systematic literature review. Rev.Colomb.Reumatol. [online]. 2020, vol.27, suppl.1, pp.10-25. Epub Aug 21, 2021. ISSN 0121-8123. https://doi.org/10.1016/j.rcreu.2020.05.025.
Background:
Capillaroscopy is an essential tool for the diagnosis of systemic sclerosis. Using this exam as a prognostic factor will allow earlier intervention and probably, delay on disease progression. We aimed to evaluate the prognostic value of capillaroscopy for the prediction of systemic compromise and subtype differentiation in systemic sclerosis.
Methods:
A systematic literature search was applied in the following electronic databases: Medline, PubMed, Embase, Cochrane, and Lilacs. The research question was designed based on the PICOT model, and the search strategy was built using the MeSH terms "Microscopic Angioscopy," "Scleroderma systemic," "Scleroderma diffuse," Scleroderma Limited," "Early Diagnosis" and Boolean operators. The language was restricted to papers published in Spanish or English, from 1990 to 2019. The search terms were explored for each database, and new terms were added, as appropriate. The searches were made again before the final analyses and further studies were retrieved for inclusion at that time. Reference lists of included studies and recent aligned systematic reviews were also screened. Gray literature was not considered in this review.
Results:
A total of 183 articles were found in the selected databases: Medline (n: 115), Embase (n: 66), Cochrane (n: 2), Lilacs (n: 0). After excluding articles due to duplication, a total of 66 studies were selected. Within these articles, a screening process was applied based on the title and abstract, taking into account the eligibility criteria, finally obtaining 21 references. Two researchers assessed the selected articles, and all disagreements were solved by consensus. Finally, a total of 14 articles were included.
Conclusions:
The different abnormalities found in capillaroscopy, especially loss of capillaries, have been consistently associated not only with organ involvement but also with severity of the disease, especially with vascular manifestations (digital ulcers and pulmonary hypertension).
The importance of capillaroscopy is not only its diagnostic value but also its predictive value with its consequent implications in the follow-up and management of systemic sclerosis.
