RESUMEN

OBJECTIVE: In seeking new approaches to improve lupus pregnancy outcomes, we study the association between pregnancy planning, behaviors recommended by American College of Rheumatology's Reproductive Health Guideline 2020, and pregnancy and infant outcomes. METHODS: Lupus pregnancies in a prospective registry (1/1/2018 to 4/1/2020) were classified as planned or not-planned using the patient-reported London Measure of Unplanned Pregnancy. These groups were compared for demographics, pre-pregnancy disease activity, pregnancy planning behaviors, and delivery outcomes. RESULTS: Among 43 women with 43 singleton pregnancies the average age was 29.4 years and 42% were Black. Overall, 60% were planned pregnancies and 40% were not-planned (16 ambivalent, 1 unplanned). Women with not-planned pregnancies had lower age, income, and education, and more required Medicaid. Women with not-planned pregnancies were more likely to conceive when lupus activity was higher (p = 0.001), less likely to receive pre-pregnancy counseling with a rheumatologist (p = 0.02), and less likely to continue pregnancy-compatible medications (p = 0.03). Severe PROMISSE adverse pregnancy outcomes (APOs) and severe neonatal outcomes were higher among women with not-planned than planned pregnancies (43% vs 0% p = 0.003; 70% vs 30% p = 0.06). CONCLUSION: This study identifies pregnancy intention as a potentially modifiable risk factor for poor outcomes in women with lupus. It highlights a unique population of women with lupus at high risk for pregnancy and infant complications: those ambivalent about pregnancy. These women may not be effectively engaging in health behaviors that prevent pregnancy nor those that will prepare for a safe pregnancy. With effective pregnancy planning and contraception guidance, we may decrease their risk for maternal-fetal morbidity and mortality.

RESUMEN

Objectives: aPL are frequently present in SLE. In a well characterized SLE cohort we aimed at investigating the prevalence of aPL and assessing their analytical performance and clinical association by testing criteria specificities including LA, aCL IgG and IgM, anti-ß2-glycoprotein 1 (antiß2GP1) IgG and IgM, as well as the non-criteria aPS-PT IgG and IgM and anti-ß2GP1 domain 1 (aD1) IgG. Methods: We included 178 patients satisfying the ACR SLE classification criteria, from whom 283 samples and thrombotic events were collected longitudinally. Each sample was tested for criteria and non-criteria aPL using validated techniques in a single centre. Results: All assays provided highly reproducible results. Of the samples, 42.5% were positive for at least one criteria assay, 20.5% showed double positivity and 12.6% triple positivity. All criteria and non-criteria specificities persisted over time. Most antibody titres were only moderately correlated; however, strong correlation was observed on one hand between aD1 IgG, antiß2GP1 IgG and aCL IgG, and on the other between aPS-PT IgG and LA. aD1 IgG titres were extremely elevated in triple-positive samples. aPS-PT IgG by itself, and jointly with LA, was associated with thrombosis, an association mostly driven by venous thrombotic events. Conclusions: In this SLE cohort, the non-criteria aPL aD1 IgG and aPS-PT IgG performed differently. aD1 IgG was highly enriched in triple-positive samples, and aPS-PT IgG, jointly with LA, was associated with thrombotic events.

RESUMEN

AIM: To determine if there are ethnic differences in the prevalence of antiphospholipid syndrome (APS), clinical presentation and autoantibody profile between Roma and Caucasian patients with systemic lupus erythematosus (SLE). METHOD: A cross-sectional study was conducted including data from Roma and Caucasian SLE patients consecutively attending six hospitals in Spain. Socio-demographic characteristics, prevalence of APS, clinical and analytical features of SLE and APS were compared between ethnic groups. RESULTS: Data from 52 Roma and 98 Caucasian SLE patients were included. Roma SLE patients had a higher risk (odds ratio 2.56, 95% CI 1.02-6.39) and prevalence of APS (28.8% vs. 13.3%, P = 0.027). Furthermore, Roma SLE patients had a statistically significant higher prevalence of abortions (23.5% vs. 10.2%, P = 0.049). In relation to other APS diagnostic criteria, Roma SLE patients had a non-statistically significant higher prevalence of fetal deaths (14.3% vs. 5.1%, P = 0.106) and thrombotic events (21.1% vs. 12.2%, P = 0.160). In relation to SLE clinical features, Roma patients had a significantly higher prevalence of arthritis (75% vs. 57.1%, P = 0.034) and non-significant higher prevalence of serositis (44.2% vs. 29.6%, P = 0.104), discoid lesions (11.5% vs. 5.1%, P = 0.191), oral ulcers (46.1% vs. 34.7%, P = 0.218) and livedo reticularis (21.1% vs. 15.3%, P = 0.374). No statistically significant differences were found in the Systemic Lupus International Collaborating Clinics Damage Index or the autoimmune serological profile. CONCLUSION: Prevalence and risk of APS were significantly higher in Roma SLE patients. Furthermore, Roma patients had a significantly higher prevalence of abortions and a non-significant higher prevalence of fetal deaths and thrombotic events.

RESUMEN

We report on a 21-year-old Nigerian girl with toe gangrene, which is one of the most unlikely forms of presentation of antiphospholipid syndrome among Africans. The essence of this case report is to raise awareness that, although antiphospholipid syndrome typically presents in Africans in association with a pregnancy-related event or a neuropathology, it should be considered as a differential diagnosis in all African patients with unexplained vasculitis. A high index of suspicion and early treatment will prevent toe amputations and reduce mortality rates.

RESUMEN

OBJECTIVES: Ethnic differences in systemic lupus erythematosus (SLE) have been previously described in the multiethnic Malaysian population. However, there have since been many demographic and socioeconomic changes in the country. The aim of this study is to re-examine the clinical and immunological profiles of Malaysian SLE patients of different ethnic backgrounds. METHODS: Consecutive follow-up patients at the University Malaya Medical Centre (UMMC) from July 2010 until March 2011 were included in the study. RESULTS: The most common clinical manifestations were malar rash (61.3%), arthritis (52.3%), haematological disease (51.6%), oral ulcers (51%) and renal disease (40.6%). Ethnic Indians had fewer malar and discoid rashes but were at higher risk of arthritis, serositis, renal and neuropsychiatric disease compared to Malays and Chinese Malaysians. Antiphospholipid syndrome (APS) was less common in Chinese. A longer duration of SLE correlated with a lower SLEDAI score. CONCLUSION: Overall, the spectrum disease expression was similar to the earlier Malaysian study but the frequency of the more severe disease manifestations, viz. renal, haematological, neuropsychiatric involvements and serositis, were lower. This study further emphasises differences primarily between ethnic Indians and the other races in Malaysia.

RESUMEN

UNLABELLED: In this work we evaluate the prevalence of the antiphospholipid syndrome (APS) and its impact on survival in Chinese patients with systemic lupus erythematosus (SLE). We studied a prospective cohort of southern Chinese patients who fulfilled ≥4 American College of Rheumatology criteria for SLE. The cumulative rate of survival over time was calculated by the Kaplan-Meier method. APS was defined by the 2006 updated consensus criteria. We evaluated the prevalence and manifestations of APS, and compared the survival of patients with and without APS. We followed 679 patients with SLE (92% women; age of onset, 32.5 ± 14 yr) for 9.7 ± 7.3 years. Sixty-eight (10%) patients died and 33 (4.9%) patients were lost to follow-up. Forty-four (6.5%) patients met the criteria for APS, manifested by the following: ischemic stroke (55%), deep venous thrombosis (32%), obstetric morbidity (14%), cardiovascular events (9%), and peripheral vascular disease (9%). Nine (9/44 [20%]) APS patients died, which was more frequent than the non-APS patients (59/635 [9%]; p = 0.02). The cumulative mortality of patients with APS was 4.6% at 5 years, 7.8% at 10 years, and 22.2% at 15 years, which was not significantly higher than that of non-APS patients (5.4% at 5 years, 9.2% at 10 years, and 11.3% at 15 years; p = 0.14). However, if we considered only patients with APS caused by arterial thrombosis, the presence of APS was significantly associated with mortality (hazard ratio, 2.29; 95% confidence interval, 1.13-4.64; p = 0.02). We conclude that the presence of APS increases the mortality risk of Chinese patients with SLE, which is mainly contributed by arterial thrombotic events. CLINICAL SIGNIFICANCE: 1) APS is infrequent in southern Chinese patients with SLE compared to white patients. 2) Arterial thrombosis is a more common manifestation of APS than venous thrombosis in Chinese SLE patients. 3) APS related to arterial thrombosis is associated with increased mortality in Chinese patients with SLE.

RESUMEN

To compare clinical and laboratory findings between patients with primary antiphospholipid syndrome (PAPS) versus secondary APS due to rheumatic fever (APS-RF) (according to Jones criteria). Seventy-three APS patients (Sapporo criteria) were enrolled, and demographic, clinical, and laboratory data were collected. Exclusion criteria were heart congenital abnormalities and previous infectious endocarditis. Patients were divided into two groups: PAPS (n = 68) and APS-RF (n = 5). The mean current age, disease duration, frequencies of female gender, and Caucasian race were similar in APS-RF and PAPS patients (P > 0.05). Remarkably, the frequency of stroke was significantly higher in APS-RF compared to PAPS patients (80% vs. 25%, P = 0.02). Of note, echocardiogram of these patients did not show intracardiac thrombus. No significant differences were found in peripheral thromboembolic events (P = 1.0), pulmonary thromboembolism (P = 1.0), miscarriage (P = 0.16), thrombocytopenia (P = 0.36), arterial events (P = 0.58), and thrombosis of small vessels (P = 1.0). There were no differences in the frequencies of comorbidities such as diabetes mellitus, hypertension, smoking, and hyperlipidemia in both groups (P > 0.05). The frequencies of lupus anticoagulant, IgG, and IgM anticardiolipin were similar in two groups. APS patients associated with rheumatic fever without infective endocarditis may imply a high stroke risk as compared with PAPS, and future studies are needed to confirm this finding.

RESUMEN

BACKGROUND: Increasing evidence incriminates bacteria, especially Mycoplasma fermentans, as possible arthritogenic agents in humans. The purpose of this study was to investigate M. fermentans in the bloodstream of patients with rheumatoid arthritis. METHODS: Two hundred and nineteen blood samples from patients with rheumatoid arthritis, systemic lupus erythematosus, antiphospholipid syndrome, and healthy individuals were screened by bacterial culture and direct PCR in order to detect mycoplasmas; IgM and IgG against M. fermentans PG18 were also detected by ELISA and Immunoblotting assays in patients with rheumatoid arthritis and healthy individuals. RESULTS: Blood samples from patients with antiphospholipid syndrome and healthy individuals were negative for mycoplasma by culture or direct PCR. In blood samples from patients with systemic lupus erythematosus were detected by direct PCR M. fermentans in 2/50 (2%), M. hominis in 2/50 (2%) and U. urealyticum in 1/50 (0.5%). In patients with RA M. fermentans was detected by culture in 13/87 blood samples and in 13/87 by direct PCR, however, there was only concordance between culture and direct PCR in six samples, so M. fermentans was detected in 20/87(23%) of the blood samples from patients with RA by either culture or PCR. Antibody-specific ELISA assay to M. fermentans PG18 was done, IgM was detected in sera from 40/87 patients with RA and in sera of 7/67 control individuals, IgG was detected in sera from 48/87 RA patients and in sera from 7/67 healthy individuals. Antibody-specific immunoblotting to M. fermentans PG18 showed IgM in sera from 35/87 patients with RA and in sera from 4/67 healthy individuals, IgG was detected in sera from 34/87 patients and in sera from 5/67 healthy individuals. CONCLUSION: Our findings show that only M. fermentans produce bacteremia in a high percentage of patients with RA. This finding is similar to those reported in the literature. IgM and IgG against M. fermentans PG18 were more frequent in patients with RA than healthy individuals.

RESUMEN

A great variety of clinical and immunological features have been described in patients with the antiphospholipid syndrome (APS), but information on their prevalence and characteristics in Latin American mestizo patients with the primary APS is scarce. To analyze the prevalence and characteristics of the main clinical and immunological manifestations in a cohort of patients with primary APS of mestizo origin from Latin America and to compare them with the European white patients, clinical and serological characteristics of 100 patients with primary APS from Colombia, Mexico, and Ecuador were collected in a protocol form that was identical to that used to study the "Euro-Phospholipid" cohort. The cohort consisted of 92 female patients (92.0%) and eight (8.0%) male patients. They were all mestizos. The most common manifestations were deep vein thrombosis (DVT; 23.0%), livedo reticularis (18.0%), migraine (18.0%), and stroke (18.0%). The most common pregnancy morbidity was early pregnancy losses (54.1% of pregnancies). Several clinical manifestations were more prevalent in the Latin American mestizo than in the European patients (transient global amnesia, pulmonary microthrombosis, arthralgias, and early pregnancy losses) and vice-versa (DVT, stroke, pulmonary embolism, and thrombocytopenia). Latin American mestizo patients with primary APS have a wide variety of clinical and immunological manifestations with several differences in their prevalence in comparison with European white patients.

RESUMEN

Antiphospholipid syndrome is a systemic disorder characterized by arterial and/or venous thrombosis, thrombocytopenia, recurrent fetal loss, and presence of antiphospholipid antibodies (APA). The importance of APA in Turkish children with thrombosis is unknown. This study aimed to evaluate the frequency of APA positivity, associated risk factors other than APA, and outcome in children with APA and thrombosis. The presence of APA was investigated in 138 children presenting for evaluation of thrombosis; other prothrombotic risk factors were also studied. The frequency of APA positivity among 138 children was 11.6% (16/138). The mean age of these 16 children (10 female, 62.5%) was 9.57 +/- 4.59 years (range, 2.5-18.0 years). The mean follow-up period was 31.7 +/- 21.7 months (range, 5-60 months). Recurrence was observed during follow-up in two patients (12.5%). Ten patients (62.5%) had arterial thrombosis, five patients (31.3%) venous thrombosis, and one patient (6.3%) purpura fulminans. Among the thrombotic children with APA, 11 (68.8%) had more than one prothrombotic risk factor other than circulating APA [five patients (31.3%) had two risk factors, two patients (12.5%) had three, and four patients (25.0%) had four]. Five patients (31.3%) had no additional risk factors. APA should be tested in all children with thrombosis, especially those with arterial thrombosis.

RESUMEN

Antibodies to beta(2)-glycoprotein I (anti-beta(2)-GPI) have been reported to have stronger association with clinical antiphospholipid syndrome (APS) than anticardiolipin antibodies (aCL) and lupus anticoagulant (LAC). We investigated the sensitivity and specificity of ELISA for anti-beta(2)-GPI in Thai systemic lupus erythematosus (SLE) patients with clinical features of APS and compared the results with IgG/IgM aCL and LAC to find the test with the best association. The hospital records of 151 Thai SLE patients whose sera had been sent for either IgG/IgM anticardiolipin antibodies or lupus anticoagulant testing were reviewed. Sera of patients either without complete clinical records or those with APS-related manifestations other than vascular thrombosis and pregnancy morbidity (according to the international consensus statement on preliminary classification criteria for definite APS) were excluded. For the remaining subjects (112 patients), their sera were tested for anti-beta(2)-GPI antibody, IgG and IgM anticardiolipin, and lupus anticoagulant. The sensitivity and specificity of each method were compared by using the chi-square test. Among the 112 (74.2%) SLE patients in the study, 35 (31.3%) presented with preliminary clinical criteria for APS (i.e., vascular thrombosis and pregnancy morbidity) whereas 77 (68.7%) did not. The sensitivity and specificity of anti-beta(2)-GPI determination were 57.1 and 79.2%, respectively, whereas those of IgG aCL were 25.7 and 94.8%, of IgM aCL were 5.7 and 98.7%, and of LAC were 44.8 and 77.3%, respectively. The accuracy of the four tests showed similar association with clinical APS (accuracy of test = 72.3, 73.2, 69.6, and 68.3%, respectively). Concerning the sensitivity, specificity, and difficulty of the methods, the combination of anti-beta(2)-GPI and IgG aCL tests was the best for the diagnosis of APS in Thai SLE patients.

RESUMEN

We describe a 69-year-old woman with bilateral adrenal hemorrhage complicated with antiphospholipid syndrome (APS). She was hospitalized with nausea and vomiting in September 2003. Laboratory data demonstrated hyponatremia, hypoglycemia and prolongation of activated partial thromboplastin time (aPTT). Abdominal computed tomography showed bilateral adrenal enlargement. In October 2003, she demonstrated altered mental status with progressive hyponatremia, a high level of ACTH, and a low level of serum cortisol. She also showed thrombocytopenia, anti-cardiolipin IgG antibody, anti-beta2GPI antibody, and lupus anticoagulants. After four months, anti-cardiolipin IgG antibody was still positive. Based on these findings, she was diagnosed as having APS complicated with adrenal insufficiency due to hemorrhagic infarction. After treatment with corticosteroid, a low dose of aspirin and normal saline infusion, her condition quickly improved. Platelet counts and aPTT were also normalized. To our knowledge, this is the second Japanese case of APS complicated with bilateral adrenal hemorrhage. APS should be considered an important underlying cause of adrenal insufficiency.

RESUMEN

Investigation of the clinical epidemiology of the antiphospholipid syndrome (APS) is in its early stages. During the past 20 years, studies of antiphospholipid antibodies (aPL) and APS have been made in many countries and ethno-geographical groups. aPL appear to occur in all populations studied, with some variations noted in their frequency and in the clinical complications. Environmental and genetic factors contribute to ethnic variation and susceptibility to APS and thus inter-ethnic differences in disease patterns may be due to environmental or genetic factors, or both.

RESUMEN

OBJECTIVE: Impaired fibrinolytical outcomes may be one of the pathogenic factors for thrombotic events in patients with antiphospholipid antibodies (aPL). We investigated the consequences of the gene polymorphisms of tissue plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1) in patients positive for aPL. METHODS: Seventy-seven Japanese and 82 British patients with aPL were examined for Alu-repeat insertion (I)/deletion (D) polymorphism of the tPA gene by polymerase chain reaction (PCR), and 4G/5G polymorphism in the PAI-1 promoter gene by site-directed mutagenesis-PCR and restriction fragment length polymorphism analysis. Correlations between these polymorphisms and clinical symptoms of antiphospholipid syndrome (APS) (arterial thrombosis, venous thrombosis, miscarriage) were analyzed. RESULTS: Significant differences in the allele frequencies of these genes did not exist between patients and controls. There was no significant correlation between these gene polymorphisms and clinical symptoms of APS in patients with aPL. CONCLUSION: Polymorphisms of the tPA or PAI-1 genes probably do not significantly influence the risk of anerial thrombosis, venous thrombosis, or pregnancy morbidity in patients with aPL.

RESUMEN

Ethnic and geographic studies have contributed to knowledge of the clinical epidemiology of APS. In general, these studies support the associations of aPL with thrombosis and pregnancy morbidity, with some exceptions. Further investigation is needed to determine whether the exceptions represent interethnic variation in the clinical associations of aPL and thus provide clues to the causation of APS, or alternatively, whether methodologic factors are responsible.

RESUMEN

OBJECTIVE: To investigate the putative involvement of poly(ADP-ribose) polymerase (PARP) alleles in systemic lupus erythematosus (SLE) and primary antiphospholipid syndrome (APS). METHODS: This study of French Caucasians included 171 unrelated patients with SLE, 88 unrelated patients with primary APS, and 193 ethnically matched healthy controls. The SLE group comprised 89 patients with sporadic SLE and 82 patients with familial SLE. Patients' and controls' DNA were genotyped for the various alleles of a polymorphic CA dinucleotide repeat located within the promoter region of PARP. RESULTS: No statistically significant difference was observed for the distribution of PARP alleles between the healthy control group and each patient group or the pooled SLE patient group. CONCLUSION: The study findings strongly suggest that these alleles do not influence susceptibility to SLE or primary APS in French Caucasians.

RESUMEN

Antiphospholipid (Hughes') syndrome (APS) has not been reported in African-Americans (A-A) as frequently as in other ethnic groups. We describe eight A-A female patients with APS, including two cases of primary APS (PAPS), four with APS secondary to systemic lupus erythematosus (SLE), one with Sjögren's syndrome, and one with overlap connective tissue disease (CTD). Their mean age was 34 y (range 24-47 y). Patients were followed for a mean of 6 y (range 0.3-11 y). During follow up, both anticardiolipin (aCL) and anti-beta2glycoprotein-I (abeta2GPI) antibodies were measured in stored sera by enzyme-linked immunosorbent assay (ELISA). IgA was the most frequent isotype of aCL and abeta2GPI, and co-occurred with the IgM isotype in three of four patients with neurologic manifestations.
