A rare case of carotid stroke in young due to Takayasu Arteritis with positive anti- cardiolipin antibodies � A case report

Takayasu arteritis is a well-known yet rare form of large vessel vasculitis. Takayasu arteritis affects mainly women, and is most commonly seen in Japan, South East Asia, India, and Mexico, where it usually presents in the 2nd or 3rd decade of life. It is seen usually as pulseless disorder often with bruit at the stenosed arteries. Manifestations range from asymptomatic disease, to catastrophic strokes. Angiography remains the gold standard for diagnosis. Approximately half of those patients treated with steroids will respond, and half of the remaining patients respond to methotrexate; mycophenolatemofetil may be useful. Fertility is not adversely affected and pregnancy does not appear to exacerbate the disease, although management of hypertension is essential. We herewith report a rare case of an11 year old girl, who presented with left-sided hemiparesis, dysarthria, left UMN facial palsy, feeble pulses on right side, high Blood Pressure recordings and positive anti- cardiolipin antibodies. Imaging studies revealed Occluded right Common carotid artery, occluded right subclavian artery and stenotic right renal artery and MRI showed Acute Infarcts in Right Basal Ganglia and Right High Parietal Region, Hemorrhagic infarct in right MCA subcortical area.The diagnosis of Takayasu arteritis with recent cerebrovascular accident (left hemiparesis) with hypertension was made and the patient was started on steroids, anti-platelets, anti-hypertensives and physiotherapy.

Predictive value of anticardiolipin antibody and D-dimer combined with risk assessment profile for thromboembolism for deep vein thrombosis in elderly postoperative patients with intertrochanteric fracture of femur / 中国医师进修杂志

Objective:To investigate the predictive value of anticardiolipin antibody (ACA) and D-dimer (D-D) combined with risk assessment profile for thromboembolism (RAPT) for deep vein thrombosis (DVT) in elderly postoperative patients with intertrochanteric fracture of femur (IFF).Methods:The clinical data of 123 elderly patients with IFF in Suzhou Hospital Affiliated to Anhui Medical University from January 2019 to March 2022 were retrospectively analyzed. All patients underwent closed reduction intramedullary nail fixation. The patients were divided into DVT group (27 cases) and non-DVT group (96 cases) according to the presence or absence of DVT 7 d after surgery. Before surgery and 3, 5 d after operation, the ACA was detected by enzyme-linked immunosorbent assay, the D-D was detected by automatic coagulation analyzer, and RAPT was performed. The correlation among ACA, D-D and RAPT was analyzed by Spearman method. Multivariate Logistic regression was used to analyze the independent risk factors of DVT in elderly postoperative patients with IFF. Receiver operating characteristic (ROC) curve was used to analyze the efficacy of ACA, D-D and RAPT in predicting DVT in elderly postoperative patients with IFF. The incidences of postoperative DVT in patients with different ACA, D-D and RAPT patients were compared.Results:There were no statistical difference in ACA, D-D and RAPT before operation between the two groups ( P>0.05); the ACA, D-D and RAPT 3 and 5 d after operation in DVT group were significantly higher than those in the non-DVT group, 3 d after operation: (12.44 ± 3.25) × 10 3 RU/L vs. (8.67 ± 2.81) × 10 3 RU/L, (7.29 ± 1.49) mg/L vs. (4.70 ± 1.23) mg/L and (9.79 ± 1.15) scores vs. (9.21 ± 1.32) scores; 5 d after operation: (10.28 ± 2.16) × 10 3 RU/L vs. (6.45 ± 2.04) × 10 3 RU/L, (5.49 ± 1.26) mg/L vs. (3.63 ± 1.05) mg/L and (9.57 ± 1.08) scores vs. (9.12 ± 0.70) scores, and there were statistical differences ( P<0.01 or <0.05). Since ACA, D-D and RAPT in the two groups all reached their peak 3 d after operation, this time point was selected for analysis. Three days after operation, Pearson correlation analysis result showed that ACA and D-D were positively correlated with RAPT ( r = 0.635 and 0.630, P<0.01), and ACA was positively correlated with D-D ( r = 0.657, P<0.01). ROC curve analysis result showed that the area under the curve (AUC) of ACA and D-D combined RAPT 3 d after operation in predicting DVT in elderly postoperative patients with IFF was greater than that predicted by the 3 indexes alone (0.982 vs. 0.894, 0.870 and 0.868), the optimal cut-off values were 11.48 × 10 3 RU/L, 6.75 mg/L and 9 scores. According to the optimal cut-off value of ROC curve analysis at 3 d after operation, the patients were divided into ACA low expression (≤11.48 × 10 3 RU/L, 92 cases) and ACA high expression (>11.48 × 10 3 RU/L, 31 cases), D-D low expression (≤6.75 mg/L, 99 cases) and D-D high expression (>6.75 mg/L, 24 cases), low RAPT (≤9 scores, 93 cases) and high RAPT (>9 scores, 30 cases). The incidences of postoperative DVT in patients with ACA high expression, D-D high expression and high RAPT were significantly higher than those in patients with ACA low expression, D-D low expression and low RAPT: 43.39% (15/31) vs. 13.04% (12/92), 54.17% (13/24) vs. 14.14% (14/99) and 53.33% (16/30) vs. 11.83% (11/93), and there were statistical differences ( χ2 = 16.91, 18.06 and 22.81; P<0.01). After controlling for diabetes and other factors, multivariate Logistic regression analysis result showed that ACA, D-D and RAPT 3 d after operation were independent risk factors for DVT in elderly postoperative patients with IFF ( OR = 2.156, 2.276 and 6.106; 95% CI 1.356 to 3.429, 1.240 to 4.177 and 1.564 to 23.840; P<0.01). Conclusions:The ACA, D-D combined with RAPT can improve the predictive value of DVT in elderly postoperative patients with IFF, which has important reference significance for taking timely and effective intervention measures in early clinical stage.

Clinical observation of Gushen antai pill combined with heparin sodium in the treatment of anticardiolipin antibody-positive recurrent abortion / 中国药房

OBJECTIVE To investigate the clinical efficacy of Gushen antai pills combined with heparin sodium in the treatment of antiphospholipin antibody （ACA）-positive recurrent abortion. METHODS A total of 203 ACA-positive recurrent abortion patients were randomly divided into control group （n＝101） and combination treatment group （n＝102）. Control group was additionally treated with heparin sodium on basis of basic treatment， and combination treatment group was additionally treated with Gushen antai pills on the basis of control group. Serum samples were collected from patients， the levels of interleukin 6 （IL- 6）， tumor necrosis factor α （TNF-α）， cyclooxygenase 2 （COX-2）， β-human chorionic gonadotropin （β-HCG） and ACA were detected by enzyme-linked immunosorbent assay. The antibody-negative conversion rate was calculated， the clinical efficacy of the patient was observed， and the occurrence of adverse drug reactions was recorded. RESULTS After treatment， the pregnancy success rate and antibody-negative conversion rate of combination treatment group were significantly higher than those in the control group （P＜0.05）， and the abortion rate was significantly lower than that in the control group （P＜0.05）. Compared with before treatment， serum levels of IL-6， TNF-α and ACA in 2 groups were decreased significantly （P＜0.05）， while the levels of COX-2 and β-HCG were increased significantly （P＜0.05）； the changes of above indexes in combination treatment group were more significant（P＜0.05）. There was no statistical significance in the incidence of adverse drug reactions between 2 groups（P＞0.05）. CONCLUSIONS Gushen antai pills can maintain high expression of β-HCG， reduce the level of ACA and improve immune microenvironment in patients with ACA-positive recurrent abortion by increasing the serum level of COX-2 and decreasing the serum level of IL-6， so as to increase the success rate of pregnancy.

Detection of antiphospholipid antibody levels in normal pregnant women by chemiluminescence immunoassay and comparison between different trimesters / 中华围产医学杂志

Objective:Chemiluminescence immunoassay was used to detect the levels of anticardiolipin antibody (aCL) -IgA/IgG/IgM and anti-β2-glycoprotein Ⅰ antibody (aβ2GPⅠ) -IgA/IgG/IgM in healthy non-pregnant and pregnant women to explore the changes of antiphospholipid antibody in different pregnancy periods.Methods:This prospective study was conducted in Shandong Provincial Maternal and Child Health Care Hospital Affiliated to Qingdao University, involving normal pregnant women who underwent prenatal examination and healthy non-pregnant women with no history of adverse pregnancy who underwent progestational eugenic health examination from April 2020 to August 2021. The levels of aCL-IgA/IgG/IgM and aβ2GPⅠ-IgA/IgG/IgM were detected using BIO-FLASH chemiluminescence immunoassay analyzer and P95 as well as P99 were calculated, respectively. The difference in the six data between non-pregnant and pregnant women was compared using Mann-Whitney U test. Kruskal-Wallis H test was used to compare the change of each antibody in different pregnancy periods and Spearman correlation was used to analyze the correlation between different trimester and the levels of aCL-IgA/IgG/IgM and aβ2GPⅠ-IgA/IgG/IgM. Results:A total of 454 cases met the inclusion criteria, and 435 cases were included in the analysis after excluding 19 cases, among them 110 were non-pregnant women and 325 were pregnant women, including 110 cases in the first trimester (≤13 +6 weeks), 110 cases in the second trimester(14 +0-27 +6 weeks), and 105 cases in the third trimester (≥28 weeks). P99 value of aCL-IgA/IgG/IgM and aβ2GPⅠ-IgA/IgG/IgM in the non-pregnant women were 7.31, 14.70, 7.92, 3.58, 13.60, and 4.95 CU, which in the pregnant women were 5.90, 12.78, 5.70, 1.60, 10.65, and 3.90 CU, and were all lower than the cut-off value of 20 CU that given by the analyzer manufacturer. The levels of aCL-IgA/IgG/IgM, and aβ2GPⅠ-IgG/IgM in the pregnant women were significantly decreased comparing with the non-pregnant women [aCL-IgA: 1.90 CU (1.40-2.70 CU) vs 2.90 CU (2.20-3.83 CU), Z=－7.14; aCL-IgG: 3.00 CU (2.20-4.50 CU) vs 6.10 CU (4.20-7.83 CU), Z=－10.26; aCL-IgM: 1.40 CU (1.10-2.30 CU) vs 2.65 CU (2.08-3.73 CU), Z=－8.87; aβ2GPⅠ-IgG: 3.50 CU (2.60-4.90 CU) vs 4.75 CU (3.60-5.93 CU), Z=－5.45; aβ2GPⅠ-IgM: 0.70 CU (0.50-1.20 CU) vs 1.00 CU (0.60-1.53 CU) , Z=－3.73; all P<0.001]. The aCL-IgA level in the third trimester was higher than those in the first and second trimester (both P<0.05). The levels of aCL-IgG/IgM in the second trimester and aβ2GPⅠ- IgG in the second and third trimesters were significantly decreased than those in the first trimester (all P<0.05). Spearman analysis showed that aCL-IgG/IgM, aβ2GPⅠ-IgA/IgM had no significant correlation with the pregnancy period (the first, second and the third trimester) (all P>0.05). However, a weak correlation between the aCL-IgA, aβ2GPⅠ- IgG and the pregnancy period was observed ( r=0.28 and－0.49, both P<0.001) Conclusions:P99 value of aCL-IgA/IgG/IgM and aβ2GPⅠ-IgA/IgG/IgM levels in normal pregnant women and non-pregnant women are lower than the cut-off value of 20 CU given by the analyzer manufacturer. The levels of aCL-IgA/IgG/IgM and aβ2GPⅠ-IgG/IgM during pregnancy are lower than those before pregnancy and fluctuate with the pregnancy period, but have no significant correlation with the pregnancy period. The clinical diagnosis of antiphospholipid syndrome should be made according to the cut-off values of aCL-IgA/IgG/IgM and aβ2GPⅠ-IgA/IgG/IgM determined by each laboratory.

Correlations of anti-cardiolipin antibody and anti-β2 glycoprotein I antibody with ischemic stroke in patients with systemic autoimmune diseases / 中国基层医药

Objective:To correlate anti-cardiolipin antibody (aCL) and anti-β2 glycoprotein I antibody (aβ2GPI) with ischemic stroke (IS) in patients with systemic autoimmune diseases (SADs).Methods:A total of 104 patients with SADs who received treatment in the Affiliated Hospital of North Sichuan Medical College during January to December 2019 were included in this study. They were divided into two groups whether they had IS (IS group, n = 42) or not (non-IS group, n = 62). aPL positive rate was qualitatively compared between the IS and non-IS groups. aCL and aβ2GPI expression levels were quantitatively compared between the IS and non-IS groups. Logistic regression analysis was performed to evaluate the risk factors for IS in patients with SADs. Results:aPL positive rate in the IS group was significantly higher than that in the non-IS group [61.9% (26/42) vs. 40.3% (25 /62), χ2 = 4.66, P = 0.031]. The aCL-IgM and aβ2GPI-IgM levels in the IS group were (22.82 ± 27.27) RU/mL and (18.70 ± 23.95) RU/mL, respectively, which were significantly higher than those in the non-IS group [(13.34 ± 8.43) RU/mL, (7.61± 5.80) RU/mL, t = -2.18, -2.76, P = 0.034, 0.009]. Logistic regression analysis showed that aPL is an independent risk factor for IS ( P = 0.037). Conclusion:aCL and aβ2GPI are closely related to the occurrence of IS and are the independent risk factors for IS in patients with SADs.

Retinal ischemia as the first manifestation of antiphospholipid antibody syndrome / Isquemia retiniana como primeira manifestação da síndrome do anticorpo antifosfolipídio

ABSTRACT Antiphospholipid antibody syndrome (APS) is characterized by the development of venous and/or arterial thrombosis and by gestational morbidity (recurrent fetal losses) in the presence of antiphospholipid antibodies. We report the case of a 38-year-old woman who was diagnosed with primary APS from thromboembolic abnormalities in the retinal periphery that led to retinal ischemia. The aim of this study is to share with physicians and medical undergraduates an atypical manifestation of the syndrome that is the most common acquired thrombophilia, that should be part of the diagnostic routine of all clinical specialties.

RESUMO A síndrome do anticorpo antifosfolipídio (SAAF) caracteriza-se pelo desenvolvimento de tromboses venosas e/ou arteriais e pela morbidade gestacional (perdas fetais recorrentes) na presença de anticorpos antifosfolipídicos. Foi relatado o caso de uma paciente de 38 anos que foi diagnosticada com SAAF primária, a partir de alterações tromboembólicas na periferia da retina, que levaram à isquemia retiniana. O objetivo desse estudo é compartilhar com médicos e acadêmicos de medicina uma manifestação atípica da síndrome que é a trombofilia adquirida mais comum, devendo fazer parte da rotina diagnóstica de todas as especialidades clínicas.

Clinical and laboratory characteristics of Brazilian versus non-Brazilian primary antiphospholipid syndrome patients in AntiPhospholipid Syndrome Alliance for Clinical Trials and InternatiOnal Networking (APS ACTION) clinical database and repository

Abstract Background: Antiphospholipid syndrome (APS) is characterized by episodes of thrombosis, obstetric morbidity or both, associated with persistently positive antiphospholipid antibodies (aPL). Studying the profile of a rare disease in an admixed population is important as it can provide new insights for understanding an autoimmune disease. In this sense of miscegenation, Brazil is characterized by one of the most heterogeneous populations in the world, which is the result of five centuries of interethnic crosses of people from three continents. The objective of this study was to compare the clinical and laboratory characteristics of Brazilian vs. non-Brazilian primary antiphospholipid syndrome (PAPS) patients. Methods: We classified PAPS patients into 2 groups: Brazilian PAPS patients (BPAPS) and PAPS patients from other countries (non-BPAPS). They were compared regarding demographic characteristics, criteria and non-criteria APS manifestations, antiphospholipid antibody (aPL) profile, and the adjusted Global Antiphospholipid Syndrome Score (aGAPSS). Results: We included 415 PAPS patients (88 [21%] BPAPS and 327 [79%] non-BPAPS). Brazilian patients were significantly younger, more frequently female, sedentary, obese, non-white, and had a higher frequency of livedo (25% vs. 10%, p < 0.001), cognitive dysfunction (21% vs. 8%, p = 0.001) and seizures (16% vs. 7%, p = 0.007), and a lower frequency of thrombocytopenia (9% vs. 18%, p = 0.037). Additionally, they were more frequently positive for lupus anticoagulant (87.5% vs. 74.6%, p = 0.01), and less frequently positive to anticardiolipin (46.6% vs. 73.7%, p < 0.001) and anti-ß2-glycoprotein-I (13.6% vs. 62.7%, p < 0.001) antibodies. Triple aPL positivity was also less frequent (8% vs. 41.6%, p < 0.001) in Brazilian patients. Median aGAPSS was lower in the Brazilian group (8 vs. 10, p < 0.0001). In the multivariate analysis, BPAPS patients still presented more frequently with livedo, cognitive dysfunction and sedentary lifestyle, and less frequently with thrombocytopenia and triple positivity to aPL. They were also less often white. Conclusions: Our study suggests a specific profile of PAPS in Brazil with higher frequency of selected non-criteria manifestations and lupus anticoagulant positivity. Lupus anticoagulant (not triple positivity) was the major aPL predictor of a classification criteria event.

Diagnosis and treatment of hepatic sinusoidal obstruction syndrome after liver transplantation: a single-center experience / 器官移植

Objective To summarize the incidence, diagnostic and therapeutic experience of hepatic sinusoidal obstruction syndrome (HSOS) after liver transplantation. Methods Clinical data of 4 patients with HSOS after liver transplantation were retrospectively analyzed. The incidence, clinical manifestations, imaging and pathological characteristics of HSOS after liver transplantation were collected, and the treatment methods and clinical outcomes of patients with HSOS were analyzed. Results The incidence of HSOS after liver transplantation was 0.8%(2/239), and the median time of onset was 4.5(1.7, 9.0) months after liver transplantation. The clinical manifestations of HSOS mainly included abdominal distension, ascites, hepatomegaly, increased bilirubin, and renal insufficiency in partial cases. Enhanced abdominal CT scan of 4 patients with HSOS showed uneven spot-like enhancement and the liver histopathological examination mainly showed the signs of hepatic sinusoidal dilatation complicated with congestion. Four patients were administered with an adjusted regime of immunosuppressant by replacing tacrolimus (Tac) with ciclosporin and adding anticoagulant therapy with warfarin. One patient received transjugular intrahepatic portosystemic shunt (TIPS). After treatment, the symptoms of 3 patients were completely relieved, and 1 patient died. One of the 3 surviving patients died from pulmonary infection and gastrointestinal bleeding. Conclusions HSOS is a rare and fatal complication after liver transplantation. Timely diagnosis and treatment can avoid the incidence of graft failure and improve clinical prognosis of the patients.

Antiphospholipid and Antinuclear Antibodies in Children with Idiopathic Epilepsy: A 2-Year Prospective Study

Study on the expression of antiphospholipid antibody subtypes in primary glomerulopathy / 中国实用内科杂志

OBJECTIVE: To discuss expression of antiphospholipid antibody subtypes in primary glomerular diseases. METHODS: All1021 cases who were admitted to our center between June 2015 and July 2017 in Kidney Disease Center, First Affiliated Hospital,College of Medicine, Zhejiang Universityhad renal biopsy in our center and they were praved to have primary glomerular diseases(303 cases of membranous nephropathy, 483 cases of IgA nephropathy, 76 cases of mesangial proliferative glomerulonephritis, 119 cases of minimal change nephropathy and 40 cases of focal segmental glomerulosclerosis). The levels of anti-cardiolipin(ACL) antibody subtypes(IgG, IgM and IgA)and anti-β2 glycoprotein 1(β2 GP1) antibody subtypes(IgG, IgM and IgA) were measured and compared.RESULTS: The positive rate of APA in membranous nephropathy group was highest(17.5%) and in minimal change nephropathy was lowest group(11.8%), but there were no significant differences among the groups. The positive rates of ACL in IgA nephropathy and mesangial proliferative glomerulonephritis were 11.4% and 14.5% respectively, which were significantly higher than those of anti-β2 GP1 antibody(P< 0.001, P = 0.009 respectively). The positive rate of anti-β2 GP1 antibody in membranous nephropathy group was 11.2%,significantly higher than that in the other four groups. The positive rate of ACL-IgM in mesangial proliferative glomerulonephritis group was 13.2%, which was significantly higher than that in the other four groups(P< 0.05). The positive rate of ACL-IgA in IgA nephropathy group was 5.8%, which was significantly higher than the other four groups, and there was no statistical difference(P<0.05).CONCLUSION: Antiphospholipid antibody is positive in patients with primary glomerular diseases, and the positive rate of its subtypes varies among the different pathological types of glomerulonephritis, which can be helpful to differential diagnosis and treatment of the disease.

Clinical manifestations and prognosis of SLE patients with positive anti-cardiolipin antibodies / 医学研究生学报

Objectives Anticardiolipin antibody (aCL) is an important component of antiphospholipid antibody (aPL) and a marker antibody of antiphospholipid syndrome (aPS). APL is positive in 20% to 40% of patients with systemic lupus erythematosus(SLE). This article investigated the clinical features and prognosis of SLE patients with aCL. Methods From January 1999 to December 2009, 495 cases of SLE patients detected aCL who were hospitalized for the first time in 26 hospitals in Jiangsu Province including Nanjing Drum Tower Hospital were divided into aCL-positive group and aCL-negative group according to the test results. The patients were followed up in survival status, and the demographic characteristics, affected organs, laboratory tests, treatment drugs, and prognosis were compared between two groups. Results 146 of the SLE patients in this group were positive for aCL. The proportion of women in aCL- positive group (96.6%) was significantly higher than that in aCL-negative group (90.8%), and the difference was statistically significant (P<0.05). The proportion of anemia (74.7% vs 61.3%), decreased C3(81.5% vs 71.1%), positive antinuclear antibody(97.2% vs 92.4%), and positive anti-dsDNA antibody (61.9% vs 49.6%) in aCL-positive group were significantly higher than those of aCL-negative group, and the difference was statistically significant (P<0.05). The aCL-positive group received a higher proportion of cyclophosphamide immunosuppressive therapy (39.5% vs 50.7%, P<0.05). At the end of follow-up, the mortality rate of aCL-positive group was 13.7%, and the mortality rate of aCL-negative group was 14.9% and there was no significant difference in mortality (P>0.05). Kaplan-Meier survival analysis showed that the 1-year, 5-year, and 10-year survival rates of aCL-positive group were 94.5%, 89.0%, and 82.9%, respectively, and there was no significant difference compared with aCL-negative group(P=0.776). The main causes of death in aCL-positive group were lupus encephalopathy (6 cases, 30.0%), renal failure (5 cases, 25.0%), heart failure (4 cases, 20.0%) and infection (3 cases, 15%). The main causes of death in aCL-negative group were infection (21 cases, 40.4%), lupus encephalopathy (11 cases, 21.2%) and heart failure (5 cases, 9.6%) and renal failure (4 cases, 7.7%). Conclusion SLE patients with aCL represent a high propotion in anemia, decreased C3, positive antinuclear antibody, positive anti-dsDNA antibody. There was no significant difference in disease activity and significant organ involvement between two groups. More SLE patients with aCL were treated with cyclophosphamide, and there was no significant difference in survival status between SLE patients with and without aCL during long-term follow-up.

Anticuerpos contra la cardiolipina en glomerulonefritis postestreptocócica concurrente con anemia hemolítica autoinmunitaria: a propósito de un caso / Anticardiolipin antibodies in concurrent poststreptococcal glomerulonephritis and autoimmune hemolytic anemia: A case report

En este artículo, presentamos el caso de una paciente con glomerulonefritis aguda postestreptocócica (GNAPE) y anemia hemolítica autoinmunitaria (AHAI). Además de los signos típicos de la GNAPE, la paciente tuvo un resultado positivo en la prueba de antiglobulina directa y anticuerpos contra la cardiolipina sin que presentara las manifestaciones clínicas típicas del síndrome antifosfolipídico. Este caso genera dudas respecto de la relación entre el estreptococo y el desarrollo de anemia hemolítica autoinmunitaria en los niños. Este caso destaca la posibilidad de que las infecciones estreptocócicas de nuestra paciente podrían haber causado la anemia, ya sea en el contexto de anticuerpos antifosfolipídicos preexistentes o por haber desencadenado el desarrollo de anticuerpos patogénicos, que luego lleva a la presentación clínica de hemólisis. Se presume que, en la paciente, los anticuerpos contra la cardiolipina inducidos por la infección estreptocócica podrían tener una función directa en la presentación clínica de AHAI.

We present a case of acute post-streptococcal glomerulonephritis (APSGN) with autoimmune hemolytic anemia (AIHA). Along with the classic findings of APSGN, the patient had a positive direct antiglobulin test and an anticardiolipin antibody without any typical clinical manifestations of antiphospholipid syndrome (APS). This case raises questions of the relationship between Streptococcus and the development of autoimmune hemolytic anemia in children. Our case highlights the possibility that the streptococcal infections in this patient might be responsible for her anemia, either in setting of underlying antiphospholipid antibodies, or in having triggered the development of pathogenic antibodies, which subsequently leads to the clinical evolution of hemolysis. It is presumed that in our case, the anticardiolipin antibody induced by streptococcal infection may play a direct role in the clinical evolution of AIHA.

Sudden sensorineural hearing loss: A missed opportunity for treatment

@#Sudden sensorineural hearing loss (SSNHL) is an otology emergency and carries significant morbidity if the diagnosis is missed. It can present to any specialty but in our local setting the patient usually presents to primary care as it is easily accessible. We present a case of SSNHL that was initially presented to a primary care centre and the patient was reassured without any investigation being carried out. SSNHL has many causes thus making diagnosis difficult. However, with knowledge of its possible, a diagnosis can be made and appropriate management can be advocated to the patient. Hence, we discuss the three main causes of SSNHL, while emphasizing the immune system-mediated mechanism as the main cause in this case.

Síndrome antifosfolípido catastrófico / Catastrophic antiphospholipid syndrome

El síndrome antifosfolípido está definido por la combinación de manifestaciones clínicas trombóticas y/u obstétricas y un título persistentemente alto y significativo de anticuerpos antifosfolípidos. La presencia de múltiples trombos en lechos vasculares pequeños que lleva a falla multiorgánica, simultáneamente o en menos de 1 semana, define al síndrome antifosfolípido catastrófico el cual conlleva alta mortalidad; sin embargo, la sospecha diagnóstica y la institución temprana del tratamiento, definitivamente inciden en el pronóstico de éstos pacientes(AU)

Antiphospholipid syndrome is defined by the combination of thrombotic and/or obstetric clinical manifestations and a persistently high and significant title of antiphospholipid antibodies. The presence of multiple thrombi in small vascular beds leading to multi-organ failure that occurs simultaneously or in less than 1 week, and defines the catastrophic antiphospholipid syndrome which carries high mortality, The suspected diagnosis and early treatment affects the prognosis of these patients(AU)

Objective To explore the significance of serum levels of interleukin(IL)-33,21,17, 6,the positive rates of anti-cardiolipin antibody(ACA)-IgG,ACA-IgM and anti endothelial cell antibody (AECA)-IgM in diagnosis of Kawasaki disease and prediction of coronary artery lesions. Methods Seventy children with Kawasaki disease were selected as Kawasaki disease group,and the children were divided into abnormal ultrasonic group(11 cases)and normal ultrasonic group(59 cases)according to the result of cardiac ultrasound. Fifty children with upper respiratory tract infection or bronchitis were selected as control group.The serum levels of IL-33,21,17,6 and positive rates of ACA-IgG,ACA-IgM, AECA-IgM were detected.Results The serum levels of IL-33,21,17 and 6 in Kawasaki disease acute stage were significantly higher than those in control group:(127.43 ± 10.87)ng/L vs.(69.67 ± 6.38)ng/L, (130.43 ± 11.22) ng/L vs. (87.56 ± 7.76) ng/L, (1 243.38 ± 612.08) ng/L vs. (397.26 ± 182.16) ng/L, (438.35 ± 101.78)ng/L vs.(213.74 ± 104.52)ng/L;the positive rates of ACA-IgG,ACA-IgM and AECA-IgM were significantly higher than those in control group: 37.1%(26/70)vs.8.0%(4/50),32.9%(23/70) vs.6.0%(3/50)and 34.3%(24/70)vs.8.0%(4/50),and there were statistical differences(P<0.01).The acute stage serum levels of IL-33, 21, 17 and 6 in abnormal ultrasonic group were significantly higher than those in normal ultrasonic group:(135.92 ± 11.56)ng/L vs.(123.48 ± 10.14)ng/L,(138.29 ± 11.86) ng/L vs.(128.08 ± 10.94)ng/L,(2 042.47 ± 968.43)ng/L vs.(1 096.59 ± 502.82)ng/L,(495.58 ± 103.04) ng/L vs. (402.67 ± 98.26) ng/L; the positive rates of ACA-IgG, ACA-IgM and AECA-IgM were significantly higher than those in normal ultrasonic group:7/11 vs.32.2%(19/59),8/11 vs.25.4%(15/59) and 7/11 vs. 28.8% (17/59), and there were statistical differences (P < 0.01 or <0.05). In Kawasaki disease, the acute stage serum levels of IL-33, 21, 17 and 6 were significantly higher than those in subacute stage:(127.43 ± 10.87)ng/L vs.(94.48 ± 8.56)ng/L,(130.43 ± 11.22)ng/L vs.(91.78 ± 8.03) ng/L, (1 243.38 ± 612.08) ng/L vs. (527.12 ± 236.94) ng/L and (438.35 ± 101.78) ng/L vs. (308.41 ± 144.09)ng/L,and there were statistical differences(P<0.01).Conclusions IL-33,21,17,6 and ACA-IgG, ACA-IgM, AECA-IgM participates in the process of Kawasaki disease vasculitis and coronary artery damage,which can assist the early diagnosis of Kawasaki disease and predict the coronary artery lesions.

Síndrome Antifosfolipídico Catastrófico / Catastrophic Antiphospholipid Syndrome

El término síndrome antifosfolipídico (SAF) "catastrófi-co" fue introducido para definir una forma grave y rá-pidamente evolutiva de SAF que conduce a insuficien-cia multiorgánica. Los pacientes con SAF catastrófico tienen en común: a) evidencia clínica de afectación orgánica múltiple (3 o más órganos); b) evidencia ana-tomopatológica de la oclusión de múltiples vasos de pequeño calibre (aunque algunos pacientes presentan también trombosis de los vasos de gran calibre) y c) confirmación de la presencia de anticuerpos antifosfoli-pídicos (AAF), generalmente a títulos elevados. Aunque representan menos del 1% de todos los pa-cientes con SAF, generalmente se encuentran en una situación médica urgente que requiere un seguimiento clínico exhaustivo y un tratamiento precoz y enérgico.

The term anti-phospholipid syndrome (APS) "catastro-phic" was introduced to define a serious and rapidly progressive form of APS which leads to multi-organ failu-re. Patients with catastrophic APS have in common: a) a clinical evidence of multiple organ involvement (3 or more organs); b) pathological evidence of occlusion of multiple small vessels (although some patients have also thrombosis of large vessels) and c) confirmation of the presence of anti-phospholipid antibodies (APAs), usually at high titers.Although they represent less than 1% of all patients with APS, they usually found in an urgent medical situation that requires a thorough clinical monitoring and an early and vigorous treatment.

Value of detections of antinuclear antibody combined with anti-cardiolipin antibody, anti-sperm antibody and anti-β2-glycoprotein I antibody in female infertility / 国际检验医学杂志

Objective To investigate the value of detections of anti‐nuclear antibody (ANA) combined with anti‐cardiolipin anti‐body (ACA) ,anti‐sperm antibody (AsAb) and anti‐beta 2 glycoprotein I (β2 GPI) antibody in the diagnosis of female infertility dis‐ease .Methods A total of 187 female cases of infertility (infertility group) were detected serum ANA and AsAb by the indirect im‐munofluorescence assay ,and ACA andβ2 GPI antibody by the enzyme linked immunosorbent assay (ELISA) .ANA ,ACA ,AsAb andβ2 GPI antibody also were detected in 80 females cases of normal fertility (normal group) .Results Among 187 cases of female infer‐tility ,ANA positive rate was 18 .1% (34/187) and which in the normal group was 2 .5% (2/80) .The ACA positive rate was 22 .3%(43/187) in the infertility group and 5 .0% (4/80) in the normal group ;the AsAb positive rate was 18 .7% (35/187) in the infertil‐ity group and 3 .8% (3/80) in the normal group ;theβ2 GPI positive rate was 20 .3% (38/187) in the infertility group and 3 .8% (3/80) in the normal group;the differences between the two groups had statistical significance (P<0 .05) .Conclusion Infertility is closely correlated with the in vivo existence of ANA ,ACA ,AsAb andβ2 GPI antibody ,the joint detection is conducive to find the e‐tiology of infertility and improve the clinical diagnosis rate .

Multiple Spontaneous Intracerebral Hematoma without Presenting Risk Factors

The incidence of intracerebral hemorrhage in those aged 45–84 years is 0.3-0.5%. In people over 80 years of age, this incidence increases 25-fold compared with that of the total population. The most common causes of spontaneous intracerebral hemorrhage in the younger population are vascular malformation, aneurysm, and overuse of drugs. In contrast, common causes in the elderly include hypertension, tumors, and coagulation disorders. Here, we present a case involving a 72-year-old male patient who, without any of these predisposing conditions, was admitted to the hospital with spontaneous intracerebral hemorrhage and showed signs of multifocal intracerebral hemorrhage during his stay. We conclude that spontaneous intracerebral hemorrhage can occur without any predisposing factors, and can lead to a patient's death. Therefore, the possibility of recurrent spontaneous intracerebral hemorrhage must be considered in patients with primary spontaneous intracerebral hemorrhage.

Detection and clinical significance of anti-cardiolipin and anti-β2 glycoprotein Ⅰ antibodies in missed abortion women / 中国综合临床

Objective To investigate the correlation of the anti-cardiolipin(aCL) antibodies and anti-β2 glycoprotein Ⅰ(anti-β2GPI) antibodies in missed abortion women.Methods Fourteen patients diagnosed missed abortion were chose as trial group,while 20 normal females received induced abortion in the same time as control group.Chemiluminescence method was used to measure the serum levels of IgG/IgM aCL and IgG/IgM anti-β2GPI antibodies in the two groups.Results The median levels of serum IgM aCL antibodies and serum IgM anti-β2GPI antibodies in trial group were significantly higher than those of control group(21.3(2.2-39.4)KU/L vs.6.0(1.5-10.7) KU/L,11.9(1.2-25.4) KU/L vs.1.9(1.1-4.0) KU/L;u=2.031,2.912;P ＜0.05).There were no significant differences in terms of the levels of serum IgG aCL antibodies and serum IgG anti-β2GPI antibodies between trial group and control group (P＞0.05).Conclusion There is correlation between IgM aCL as well as IgM anti-β2GPI antibodies and missed abortion,so in reducing the incidence of missed abortion,early and dynamic detection of anti-cardiolipin and anti-β2 glycoprotein I antibodies in childbearing women has a certain clinical significance.

Resultados maternos y perinatales en mujeres con diabetes gestacional según criterios de pesquisa / Maternal and perinatal health in women with gestational diabetes research results according to criteria

OBJETIVO: Conocer los resultados maternos y perinatales de mujeres con diabetes gestacional diagnosticada según los Criterios de la Asociación Internacional de Grupos de Estudio de Diabetes y Embarazo y la Asociación Latinoamericana de Diabetes. MÉTODOS: Se estudiaron ciento veintidós embarazadas con diagnóstico de diabetes gestacional, aplicando los criterios Asociación Internacional de Grupos de Estudio de Diabetes y Embarazo y Asociación Latinoamericana de Diabetes. Se compararon datos socio-demográficos, factores de riesgo para diabetes gestacional, parámetros clínicos y metabólicos durante el embarazo y la pesquisa posparto de diabetes en ambos grupos. Las determinaciones de glucemias de las pruebas de tolerancia oral a la glucosa se realizaron mediante el método enzimático. Se utilizó Chi cuadrado y t de Student para la asociación de variables. Se consideró significativo un valor de P < 0,05. RESULTADOS: Al usar los criterios de la Asociación Internacional de Grupos de Estudio de Diabetes y Embarazo, el número de pacientes con diabetes gestacional aumentó 22,95 %. No hubo diferencias en cuanto a factores de riesgo para diabetes gestacional, resultados maternos y perinatales entre los dos grupos. En el grupo según los criterios Asociación Latinoamericana de Diabetes, las glucemias 2 horas poscarga en el posparto eran más altas (P< 0,02) y resultaron casos de prediabetes. CONCLUSIONES: Se incrementó la proporción de casos con diabetes gestacional, al emplear los criterios de la Asociación Internacional de Grupos de Estudio de Diabetes y Embarazo y se detectaron más alteraciones glucémicas maternas en el posparto con los criterios Asociación Latinoamericana de Diabetes. Se requieren investigaciones ulteriores, cuyos resultados puedan contribuir a las decisiones institucionales sobre los criterios para la pesquisa de diabetes gestacional.
