Purpose: Previously, Kawasaki disease (KD) treatment with low-dose aspirin was administered for 6-8 weeks after the acute phase. However, inflammatory marker levels normalize before 6-8 weeks. In this study, we aimed to investigate the clinical outcome of short-term low-dose aspirin treatment based on inflammatory and thrombotic marker levels. Methods: We performed a retrospective review of the medical records of patients with KD who were hospitalized at Chungnam National University Hospital between September 2012 and May 2014. When fever subsided, low-dose aspirin treatment was started. Inflammatory (white blood cell count, erythrocyte sedimentation rate, and C-reactive protein) and thrombotic markers (D-dimer) were monitored at follow-ups conducted in 1- to 2-week intervals. The low-dose aspirin administration was terminated when both markers were normalized and no cardiovascular complications were observed. Results: Eighty-four patients with KD (complete KD, n=49; incomplete KD, n=35) were enrolled. The inflammatory and thrombotic marker levels were normalized within 3-4 weeks on average. At the beginning the low-dose aspirin treatment, 9 patients had coronary artery lesions but 75 did not. When the low-dose aspirin administration was terminated at the time the inflammatory marker levels were normalized, no new CALs developed during the follow-up at 6-8 weeks. Conclusion: Most of the inflammatory marker levels were normalized within 3-4 weeks after the acute phase of KD. New cardiovascular complications did not develop during the course of the short-term aspirin treatment based on the inflammatory marker levels, clinical findings, and echocardiography.

Hemorrhagic complications associated with aspirin use occur primarily at skin or gastrointestinal sites but can occasionally occur in the central nervous system. In particular, spontaneous spinal epidural hemorrhage (SSEH) associated with aspirin is very rare. We report a case of low-dose (100 mg daily) aspirin-related SSEH that was successfully treated with medical management. Our case indicates that low-dose aspirin could induce SSEH and that conservative treatment with close observation and repeated imaging studies should be considered in cases with neurological improvement or mild deficits.

Objective : To evaluate the efficacy of low-dose aspirin on IVF outcome and endometrium in patients undergoing IVF-ET. Materials and Methods : From February, 2001 to Jun, 2001, 60 infertile patients were randomly divided into study group (28 cycles) and control group (32 cycles). The study group received a daily oral dose of 25 mg of aspirin for at least 2 weeks from first visiting day. Controlled ovarian hyperstimulation was initiated in all patients with the GnRH agonist starting in the midluteal phase of the previous cycle. Results: There were no significant differences in age of the patients, basal serum E2, LH, FSH level and endometrial thickness among two groups. There were no statistically significant differences between the study group and the control group respectively in dosage ($26.5{\pm}4.8$ vs $26.2{\pm}5.3$ amples) and duration ($10.4{\pm}4.2$ vs $9.8{\pm}5.3$ days) of gonadotropin administration, serum E2 level on the hCG administration day ($1823{\pm}342$ vs $1854{\pm}543$), LH ($14.5{\pm}2.7$ vs $14.8{\pm}3.1$), FSH ($16.7{\pm}3.4$ vs $18.3{\pm}4.7$), the number of follicles > 15 mm ($13.2{\pm}6.3$ vs $12.8{\pm}5.9$), the number of oocytes retrieved ($9.2{\pm}2.4$ vs $8.4{\pm}1.7$), the number of embryos transferred ($4.7{\pm}2.0$ vs $4.7{\pm}2.0$), fertilization rate (68.4% vs 64.5%), implantation rate (21.3% vs 17.6%), and clinical pregnancy rate (28.4% vs 26.2%). The endometrial thickness and the percentage of endometrial trilaminar pattern on hCG day were significantly higher in study group than control group ($12.9{\pm}3.7mm$ vs $10.4{\pm}2.8mm$, 78.3% vs 64.5%). Conclusion: Many reports suggest that low-dose aspirin improve ovarian response, implantation rate, fertilization rate, implantation rate, and pregnancy rate by increasing the blood flow, but we couldn't prove the significant effect of low-dose aspirin on the IVF outcome except on endometrium. This may be affected by dose of aspirin, duration, and number of patients studied. This trial is small, so our results highlight the need for a large randomized controlled trial to identify the effect of low-dose as pirin on IVF-ET outcome.

Aspirin is widely used for treatment or prophylaxis of many diseases. Although aspirin is used chronically for preventing cardiovascular diseases especially, liver function is rarely monitored because of unpredictable and uncommon hepatotoxicity induced by aspirin. We evaluated changes in liver function indicators and compared to acetaminophen and NSAIDs. We retrospectively analyzed EMR data (n=28788) of patients who took study drugs and had liver function tests (LFT) during study period from 2009.7.1 to 2010.6.30 at a tertiary hospital and evaluated the above information. Patients not having LFT results at these three standard points of time (baseline, during medication, and after finishing medication) were excluded. During medication, mean changes of Alanine transaminase (ALT), Aspartate transaminase (AST), Total Bilirubin (TB) were increased and that of serum albumin (Alb) was decreased, with the largest effect from aspirin (n=461; 16.8, 14.9, 0.28, -0.24) and the smallest from celecoxib (n=127; 3.4, 5.2, 0.11, -0.16). In addition, aspirin caused more changes of blood liver function indicators in patient group with liver disease (n=128, 27.4, 26.9, 0.53, -0.3) than those in patient group without liver disease (n=357, 12.5, 13.1, 0.23, -0.24). Taking low dose aspirin for prophylaxis purpose with long-term medication may be associated with liver injury. Our study is just a signal regarding the possibility of hepatotoxicity among patients taking low dose aspirin in a hospital setting, and thus it needs to be further investigated.

Objective: Low-dose aspirin have been proposed to improving endometrial receptivity and pregnancy rate in COH-IVF by increasing endometrial perfusion. However, the effect of low-dose aspirin in COH-IVF could be negligible because there have been large quantity of other important factors responsible for changing endometrial perfusion accompanied by COH procedure. In contrast, in frozen-thawed embryo transfer cycles which were not accompanied by COH procedure, the effects of low-dose aspirin in endometrial blood flow seems to be more certain than in COH-IVF cycles. In this study, we analyzed the effect of low-dose aspirin treatment on implantation and pregnancy rates in patients undergoing frozen-thawed embryo transfer Methods: From January 2003 to December 2003, total 264 cycles from 264 patients who attended infertility clinic at Samsung Cheil Hospital were enrolled in this study. All cases included in this study, embryos were frozen and thawed at the pronuclear stage and three days after incubation, at least 2 or more good quality embryos were transferred into uterus. In study group, low dose aspirin (100 mg/day) was administrated from the first or second date of menstrual day to 9 days after embryo transfer. On the other hand, control group did not take any medicine except estradiol valerate for endometrial priming. Several variables including implantation and pregnancy rates were compared in both groups. After then, each groups were stratified by endometrial thickness checked at embryo transfer (ET) day such as (28 mm versus <8 mm) and same variables above described were compared between study and control groups. Results: The mean age, infertility duration, endometrial thickness at embryo transfer day and mean number of transferred embryo were not significantly different in both groups. Also, implantation rates (study group: 15.8%, control group: 20.5%) and pregnancy rate (study group: 45.1%, control group: 43.5%) were not significantly different between two groups. (p>0.05) After we analyzed same variables stratified by endometrial thickness checked at embryo transfer day, we could not found any significant difference between study and control groups. Conclusions: Low-dose aspirin treatment seems to have no advantage of improving implantation and pregnancy rates in patients undergoing frozen-thawed embryo transfer.

Aspirin has been widely used as analgesic and anti-inflammatory drug. Recently, it was elucidated that aspirin have anti-coaggregatory effect in low dose. This study was carried out to investigate the synthesis of aspirin derivatives from aspirin and aromatic compound of antioxidant and its biological activities. Synthesis of aspirin derivatives was prepared by esterification in the presence of 1, 1-carbonyldiimidazole. Biological activities was examined using effect of anti-coagulant on bleeding time, effect of antioxidant and effect of anti-platelet aggregation. As a result, SJ-101 showed strong antioxidative activity and anti-coagulant activity among four compounds. Anti-platelet aggregation of SJ-101 was examined by collagen, ADP, PAF method. SJ-101 exhibited more stronger activity to aspirin at collagen aggregation reaction. These finding demonstrates that SJ-101 is usefull as care drug of aging and old-disease because of its has antioxidant activity, anti-coagulant activity and anti-platelet activity.

Objective : There is no proven regimen to reduce the severity of stroke in patients with acute cerebral infarction presenting beyond the thrombolytic time window. Ozagrel sodium, a selective thromboxane A2 synthetase inhibitor, has been known to suppress the development of infarction. The antiplatelet effect is improved when aspirin is used together with a thromboxane synthetase inhibitor. Methods : Patients with non-cardiogenic acute ischemic stroke who were not eligible for thrombolysis were randomly assigned to two groups; one group received ozagrel sodium plus 100 mg of aspirin (group 1, n=43) and the other 100 mg of aspirin alone (group 2, n=43). Demographic data, cardiovascular risk factors, initial stroke severity [National Institute of Health Stroke Scale (NIHSS) and motor strength scale] and stroke subtypes were analyzed in each group. Clinical outcomes were analyzed by NIHSS and motor strength scale at 14 days after the onset of stroke. Results : There were no significant differences in the mean age, gender proportion, the prevalence of cardiovascular risk factors, stroke subtypes, and baseline neurological severity between the two groups. However, the clinical outcome for group 1 was much better at 14 days after the onset of stroke compared to group 2 (NIHSS score, p=0.007, Motor strength scale score, p<0.001). There was one case of hemorrhagic transformation in group 1, but there was no statistically significant difference in bleeding tendency between two groups. Conclusion : In this preliminary study, thromboxane A2 synthetase inhibitor plus a low dose of aspirin seems to be safe and has a favorable outcome compared to aspirin alone in patients with acute ischemic stroke who presented beyond the thrombolytic time window.

Gastric cancer is one of the leading causes of cancer-related deaths worldwide. The increased expression of cyclooxygenase (COX)-2 has been implicated in the development and progression of gastric cancers. A number of recent studies have been published evaluating the chemopreventive effect of aspirin and non steroidal anti inflammatory drungs (NSAIDs) against gastric cancer. Aspirin and NSAIDs use may reduce the risk of gastric cancer incidence and death, whereas other studies have reported contradictory results. Therefore, further study should be needed to clarify the role of aspirin and NSAIDs in the chemoprevention of gastric cancer.

목 적: 아스피린을 비롯한 NSAID의 사용이 위장관 출혈 등 여러 가지 위 장관합병증의 위험성을 증가시키는 것은 이미 잘 알려진 사실이다. 소아에서 염증성 질환이나 해열제로 사용하는 통상용량의 아스피린보다 10분의 1정도의 소용량을 사용하는 경우가 종종 있으나, 이와 연관된 위 장관 출혈의 위험성에 대한 연구는 거의 없다. 이에 저자들은 Kawasaki병으로 아스피린을 사용한 소아들을 대상으로 소용량 아스피린의 장기적 사용에 의한 위 장관 출혈의 위험성을 평가하고자 하였다. 방 법: 1995년부터 2001년 5월까지 을지병원 소아과에서 Kawasaki병으로 진단받고 입원 치료하였던 소아가운데, 임상 기록을 확인하고 보호자와 전화통화를 하여 위장관 출혈 여부를 확인할 수 있었던 소아 100명을 대상으로 하였다. 위 장관 출혈 여부는 환아의 임상 기록을 확인하고, 보호자와 직접 전화 인터뷰를 하여 소용량 아스피린 투여시 육안적 토혈, 혈변의 유무를 물어서 확인하였다. 결 과: 모두 100명의 환아가 연구 대상에 포함되었으며, 남아 63명, 여아 37명으로 이들이 아스피린 투약을 시작할 때 연령은 4~118개월이었으며, 약 75%의 환아가 3세 미만이었다. 아스피린 투약기간은 0.5~17개월로 나타났으며, 약 70%의 환아가 2~3개월 간의 투약을 시행하였다. 한 명의 환아에서 육안적 혈변이 발생하였는데, 환아는 투약 당시 18개월된 여아로 투약 1개월경 하루 한번 씩 약 1주일간 육안적 혈변을 보았으나, 복통이나 다른 증상은 동반되지 않았다. 혈변은 씨메티딘을 약 1주일간 사용한 후 호전되었으며, 이후 씨메티딘을 사용하지 않으며, 아스피린 투약을 약 3개월 가량 더 지속하였으나 더 이상의 출혈은 없었다. 100명의 환아가 총 341.5개월 동안 아스피린을 투여하였으며, 이 가운데 한 명만이 육안적 장출혈을 보여, 이를 100명의 환아가 일년동안 소용량 아스피린을 먹은 것으로 환산하면 3.5회/100명/1년의 비율로 장출혈이 발생하는 것을 의미하게 된다. 결 론: 소아에서 소용량 아스피린의 장기적 사용은 안전하나, 위 장관 출혈의 위험성을 높일 수 있으므로 해당 환아에 대한 세심한 추적관찰이 필요하며, 위 장관 출혈의 위험성을 감소시켜주기 위한 다양한 노력이 병행되어야 할 것이다.
