Abstract:
Introducción: El síndrome anVfosfolípido (SAF) es una patología autoinmune que provoca un síndrome de hipercoagulabilidad. Se puede presentar de forma aislada o asociado a otras enfermedades autoinmunes, sobre todo lupus eritematoso sistémico (LES). La clínica puede ser trombóVca y/o obstétrica. La...  Ver más
IntroducEon: AnVphospholipid syndrome (APS) is an autoimmune disorder that induces a hypercoagulable state. It can manifest independently or in associaVon with other autoimmune diseases, especially systemic lupus erythematosus (SLE). Clinical manifestaVons can be thromboVc and/or obstetric. ThromboVc symptoms vary widely, presenVng as venous and/or arterial thrombosis at various locaVons. PaVents exhibit posiVve anVphospholipid anVbodies, which along with clinical symptoms serve as diagnosVc criteria. Hypothesis: PaVents with a high-risk profile of anVphospholipid anVbodies are more likely to experience thrombosis and recurrences. Vitamin K antagonists have demonstrated the greatest efficacy in secondary prophylaxis in paVents with anVphospholipid syndrome. The quality of anVcoagulaVon could be a protecVve factor against thromboVc recurrences and associated complicaVons. ObjecVves: To analyze the thromboVc clinical presentaVon of paVents with anVphospholipid syndrome (APS) at diagnosis, laboratory characterisVcs of AnVphospholipid AnVbodies (aPL), as well as anVthromboVc therapy and recurrences in thromboVc APS paVents. Methods: Design: DescripVve, retrospecVve, single-center observaVonal study. PaVents with thromboVc anVphospholipid syndrome under current treatment and follow-up at HGU Dr. Balmis were analyzed. Data were extracted from an anonymized database, including sociodemographic, clinical, and laboratory variables. Variables were collected from the database, and means, medians, and correlaVons between parameters were analyzed using the SPSS staVsVcal analysis program. Results: Seventy-two paVents with thromboVc APS were included (59.7% female). The mean age was 60.5±14.7 years. A significant group of paVents had cardiovascular risk factors. ThromboVc localizaVon predominantly occurred in the venous territory (65.28%), with 44.7% as deep vein thrombosis in lower limbs and 34.72% in arterial locaVons, 20.83% resulVng in stroke. Forty-five percent had only one posiVve anVbody. Sixty-eight percent tested posiVve for lupus anVcoagulant. Median levels for ACL IgG, ACL IgM, aβ2GPI IgG, and aβ2GPI IgM were 55.7 [40.7-123.0], 43.9 [28.7-68.6], 127.0 [39.8-265.0], 70.7 [40.2- 100.9], respecVvely. No significant results were found between the type of posiVve anVphospholipid anVbody and thrombosis localizaVon. Seventy-five percent of paVents were on vitamin K antagonist drugs. The total percentage of paVents within therapeuVc range for INR (TTR) was 55.56%. Thirty percent of paVents experienced thromboVc recurrences. Eighty-two percent of them were posiVve for lupus anVcoagulant and 50% had two or more anVbodies. Ten (33,33%) paVents with TTR > 60% experienced recurrences compared to 4 (16.66%) with TTR < 60%. Seventy-seven percent of paVents under DOAC treatment experienced recurrences compared to 25.93% with vitamin K antagonist. Conclusions: The most common clinical form is deep venous thrombosis in lower limbs. Lupus anVcoagulant is posiVve in a significant porVon of paVents, posing a higher risk of thrombosis and recurrences. Vitamin K antagonist drugs provide greater security against new thromboVc episodes in thromboVc APS paVents. The heterogeneous clinical and biological characterisVcs of paVents complicate their clinical course. There are more types of anVphospholipid anVbodies that will become part of the laboratory diagnosVc process.
