RESUMEN

OBJECTIVE: Data on the long-term outcome of patients with childhood-onset Systemic Lupus Erythematosus (cSLE) are scarce. Aims of this study were to describe the long-term outcomes of cSLE and to identify factors associated with the development of damage and persistent disease activity. METHODS: We conducted a retrospective multicentre study using data from the PEDIALUP registry of the Juvenile Inflammatory Rheumatism (JIR) cohort database. Demographic characteristics, clinical manifestations, laboratory, radiological, histological and treatment data were collected from medical records during follow-up. RESULTS: A total of 138 patients with cSLE, diagnosed between 1971 and 2015, were included. With a median follow-up of 15.4 [9.6-22.4] years, 51% of patients had a SLICC-Damage Index score ≥ 1 at last follow-up with the musculoskeletal, cutaneous, renal, neurological, and cardiovascular damage being the most common manifestations. The proportion of patients with a SLICC-DI score ≥ 1 increased significantly with the duration of the follow-up (p< 0.001). On multivariate analysis, duration of follow-up was associated with increased risk of cumulative damage (OR 1.08, 95% CI 1.01, 1.15, p= 0.035). At the last visit, 34% of patients still had active disease with a SLEDAI score of ≥ 6. On multivariate analysis, Sub-Saharan African ethnicity was associated with 7-fold increased odds of having active disease at the last visit compared with Caucasians (OR 7.44, 95% CI 2.24, 24.74, p= 0.0002). CONCLUSION: The prevalence of damage remains high in patients with cSLE even when the diagnosis of c-SLE has been made in the recent decades.

RESUMEN

Objective To study the influence of Maghrebian ethnicity on lupus nephritis. Methods We retrospectively reviewed the files of a cohort of 194 patients with proliferative lupus nephritis followed in seven lupus centres belonging to three groups: Europeans living in Belgium/France (E; n = 111); Maghrebians living in Europe, in casu Belgium/France (ME; n = 43); and Maghrebians living in Morocco (MM; n = 40). Baseline presentation was compared between these three groups but complete long-term outcome data were available only for E and ME patients. Results At presentation, the clinical and pathological characteristics of lupus nephritis did not differ between E, ME and MM patients. Renal relapses were more common in ME patients (54%) than in E patients (29%) ( P < 0.01). Time to renal flare and to end-stage renal disease was shorter in ME patients compared to E patients ( P < 0.0001 and P < 0.05, respectively). While proteinuria measured at month 12 accurately predicted a serum creatinine value of less than 1 mg/dl at 7 years in E patients, this was not the case in the ME group, in whom serum creatinine at month 12 performed better. Conclusion Despite a similar disease profile at onset, the prognosis of lupus nephritis is more severe in Maghrebians living in Europe compared to native Europeans, with a higher relapse rate.

RESUMEN

Purpose The purpose of this study was to evaluate the safety of antithrombotic treatments prescribed during pregnancy in patients with antiphospholipid syndrome (APS). Methods This international, multicenter study included two cohorts of patients: a retrospective French cohort and a prospective US cohort (PROMISSE study). Inclusion criteria were (1) APS (Sydney criteria), (2) live pregnancy at 12 weeks of gestation (WG) with (3) follow-up data until six weeks post-partum. According to APS standard of care, patients were treated with aspirin and/or low-molecular weight heparin (LMWH) at prophylactic (pure obstetric APS) or therapeutic doses (history of thrombosis). Major bleeding was defined as abnormal blood loss during the pregnancy and/or post-partum period requiring intervention for hemostasis or transfusion, or during the peripartum period greater than 500 mL and/or requiring surgery or transfusion. Other bleeding events were classified as minor. Results Two hundred and sixty-four pregnancies (87 prospectively collected) in 204 patients were included (46% with history of thrombosis, 23% with associated systemic lupus). During pregnancy, treatment included LMWH ( n = 253; 96%) or low-dose aspirin ( n = 223; 84%), and 215 (81%) patients received both therapies. The live birth rate was 89% and 82% in the retrospective and prospective cohorts, respectively. Adverse pregnancy outcomes occurred in 28% of the retrospective cohort and in 40% of the prospective cohort. No maternal death was observed in either cohort. A combined total of 45 hemorrhagic events (25%) occurred in the retrospective cohort, but major bleeding was reported in only six pregnancies (3%). Neither heparin nor aspirin alone nor combined therapy increased the risk of hemorrhage. We also did not observe an increased rate of bleeding in the case of a short interval between last LMWH (less than 24 hours) or aspirin (less than five days) doses and delivery. Only emergency Caesarean section was significantly associated with an increased risk of bleeding (odds ratio (OR) 5.03 (1.41-17.96); p=.016). In the prospective cohort, only one minor bleeding event was reported (vaginal bleeding). Conclusion Our findings support the safety of antithrombotic therapy with aspirin and/or LMWH during pregnancy in high-risk women with APS, and highlight the need for better treatments to improve pregnancy outcomes in APS.

RESUMEN

OBJECTIVES: Develop recommendations for women's health issues and family planning in systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS). METHODS: Systematic review of evidence followed by modified Delphi method to compile questions, elicit expert opinions and reach consensus. RESULTS: Family planning should be discussed as early as possible after diagnosis. Most women can have successful pregnancies and measures can be taken to reduce the risks of adverse maternal or fetal outcomes. Risk stratification includes disease activity, autoantibody profile, previous vascular and pregnancy morbidity, hypertension and the use of drugs (emphasis on benefits from hydroxychloroquine and antiplatelets/anticoagulants). Hormonal contraception and menopause replacement therapy can be used in patients with stable/inactive disease and low risk of thrombosis. Fertility preservation with gonadotropin-releasing hormone analogues should be considered prior to the use of alkylating agents. Assisted reproduction techniques can be safely used in patients with stable/inactive disease; patients with positive antiphospholipid antibodies/APS should receive anticoagulation and/or low-dose aspirin. Assessment of disease activity, renal function and serological markers is important for diagnosing disease flares and monitoring for obstetrical adverse outcomes. Fetal monitoring includes Doppler ultrasonography and fetal biometry, particularly in the third trimester, to screen for placental insufficiency and small for gestational age fetuses. Screening for gynaecological malignancies is similar to the general population, with increased vigilance for cervical premalignant lesions if exposed to immunosuppressive drugs. Human papillomavirus immunisation can be used in women with stable/inactive disease. CONCLUSIONS: Recommendations for women's health issues in SLE and/or APS were developed using an evidence-based approach followed by expert consensus.

RESUMEN

BACKGROUND: The antimalarials (AMs) hydroxychloroquine (HCQ) and chloroquine (CQ) have demonstrated variable cutaneous response rates in cutaneous lupus erythematosus (CLE). OBJECTIVES: We sought to assess the global cutaneous response rates to HCQ and CQ, with respect to CLE subtypes, based on previously published studies. METHODS: We performed a systematic review and meta-analysis of studies published in MEDLINE, Embase and the Cochrane Library between 1965 and December 2015. The proportions of responders to AMs according to CLE subtypes were extracted from individual studies and pooled using random-effects or fixed models. The odds ratio (OR) was used as the measure of association to compare the response rates between CLE subtypes and AMs. RESULTS: Among 1990 courses of treatment with AMs from 31 included studies, the overall response rate to AMs was 63% [95% confidence interval (CI) 55-70], with important statistical heterogeneity across the included studies. HCQ had a higher overall efficacy than CQ, but this was not significant (OR 1·48, 95% CI 0·98-2·23). The response rate to AMs was different between CLE subtypes, ranging from 31% (95% CI 20-44) for chilblain lupus to 91% (95% CI 87-93) for acute CLE. The response was significantly higher for acute CLE than for subacute CLE and intermittent CLE. In case of failure of monotherapy with AM, the combination of quinacrine with HCQ or CQ seemed effective, whereas too little data were available to assess the efficacy of the switch to another AM agent. CONCLUSIONS: Wide discrepancies in cutaneous response to AMs are observed between CLE subtypes. A specific therapeutic approach considering CLE subtypes may improve CLE management.

RESUMEN

OBJECTIVES: Benefits of hydroxychloroquine (HCQ) use on physician reported outcomes are well documented in systemic lupus erythematosus (SLE). We assess for the first time the association and predictive value of blood HCQ levels towards health-related quality of life (HRQOL) in SLE. METHODS: Data from the PLUS study (a randomized, double-blind, placebo-controlled, multicentre study) were utilized. Blood HCQ levels were quantified by high-performance liquid chromatography along with HRQOL assessments (Medical Outcomes Study-SF-36) at baseline (V1) and month 7 (V2). RESULTS: 166 SLE patients' data were analysed. Mean (SD) age and disease duration were 44.4 (10.7) and 9.3 (6.8) years. Eighty-seven per cent were women. Mean (SD, median, IQR) HCQ concentrations in the blood at V1 were 660 (314, 615, 424) ng/ml and increased to 1020 (632, 906, 781) ng/ml at V2 (mean difference 366 units, 95% confidence interval -472 to -260, p < 0.001). No significant correlations between HCQ concentrations with HRQOL domains at V1 or V2 were noted. There were no differences in HRQOL stratified by HCQ concentrations. HCQ concentrations at V1 or changes in HCQ concentration (V2-V1) were not predictive of HRQOL at V2 or changes in HRQOL (V2-V1). CONCLUSIONS: No association of HCQ concentrations with current or longitudinal HRQOL were found in SLE.

RESUMEN

A causal link has long been described between estrogen and systemic lupus erythematosus activity. Contraceptive and pregnancy management is now common for lupus patients, but pregnancy continues to be associated with higher maternal and fetal mortality/morbidity in systemic lupus erythematosus patients than among the general population. Potential complications include lupus flares, obstetric complications (fetal loss, in utero growth retardation, premature birth) and neonatal lupus syndrome. Association with antiphospholipid antibodies or antiphospholipid syndrome increases the risk of obstetric complications. Anti-SSA and/or anti-SSB antibodies put fetuses at risk for neonatal lupus. Improving the outcome of such pregnancies depends upon optimal systematic planning of pregnancy at a preconception counseling visit coupled with a multidisciplinary approach. Absence of lupus activity, use of appropriate medication during pregnancy based on the patient's medical history and risk factors, and regular monitoring constitute the best tools for achieving a favorable outcome in such high-risk pregnancies. The aim of this review is to provide an update on the management of contraception and pregnancy in systemic lupus erythematosus, cutaneous lupus and/or antiphospholipid syndrome in order to reduce the risk of complications and to ensure the best maternal and fetal prognosis.

RESUMEN

OBJECTIVES: Pericardial involvement is a frequent manifestation of systemic lupus erythematosus (SLE). Growing evidence suggests that colchicine may be useful for acute or recurrent pericarditis. We report for the first time a series of 10 consecutive cases of SLE with pericarditis treated with colchicine. METHODS: Inclusion criteria in this retrospective study were diagnosis of SLE, pericarditis and receiving colchicine. RESULTS: We included 10 consecutive cases of SLE with pericarditis treated with colchicine (nine women, mean age at the index pericarditis 35 ± 12 years). Pericarditis was the initial manifestation of SLE for two patients, whereas eight patients had SLE lasting for a median of 2.5 years (15 days to 13 years) and had received prednisone (n = 7, 2-30 mg/d), hydroxychloroquine (n = 7), azathioprine (n = 3), methotrexate (n = 2), and mycophenolate mofetil (n = 1). For six patients, pericarditis was associated with other SLE manifestations. Altogether, colchicine avoided the use (n = 2) or increase in dosage (n = 5) of steroids in seven cases; the increase in steroids dosage was minimal for two patients. Colchicine 1 mg was given for a median of 39 days (10 days to 54 months). Symptoms completely resolved after a median of 2.5 days (1-30 days) after initiation of colchicine. Colchicine was maintained or resumed in six patients to prevent recurrence, with no further relapse. CONCLUSIONS: Colchicine may be safe and effective in treating SLE pericarditis and used as a steroids-sparing agent. These preliminary results need to be confirmed in a larger study with longer follow-up.

RESUMEN

BACKGROUND: Transverse myelitis is a rare complication of systemic lupus erythematosus (SLE). This retrospective multicentre study identifies the prognostic factors in a relatively large patient series. PATIENTS AND METHODS: Twenty patients fulfilled the SLE criteria of the ACR classification and the Transverse Myelitis Consortium Working Group. A severe neurological flare was defined as muscle strength grade <3/5 in more than half the muscle groups at the motor neurological level. Inability to run or another significant ambulation-unrelated disability was considered as 'unfavourable neurological outcome'. RESULTS: Myelitis was the first SLE symptom in 12 patients; in the eight others, it occurred 8.6 years (median delay) after SLE onset. Eleven patients presented severe neurological impairments. The treatment included corticosteroids in all patients associated with intravenous cyclophosphamide in 11 and/or hydroxychloroquine in 14. Unfavourable outcomes were observed in 53% of the patients at six months and in 28% at end of follow-up (median: 5.9 years). An initial severe neurological impairment and no cyclophosphamide use were associated with unfavourable neurological outcomes at six months and at end of follow-up, respectively. CONCLUSION: Transverse myelitis may reveal SLE or occur more than 10 years after SLE diagnosis. The initial severity of the neurological flare (with paraplegia) is the main prognostic marker. The study provides arguments for cyclophosphamide use.

RESUMEN

OBJECTIVE: The objective is to study the course and outcome of fetuses with congenital atrioventricular block (AVB) in a single centre. METHODS: Retrospective analysis of cases diagnosed prenatally with second and third degree AVB. The clinical characteristics and outcome of fetal AVB were evaluated including in utero treatment. RESULTS: Sixty-two cases were studied. AVB was associated with a congenital heart defect (CHD-AVB) in 17 cases (27%), whereas it was isolated (i-AVB) in 45 (73%), 42 of which were associated with maternal antibodies. There were nine (52.9%) live births in the CHD-AVB group, five of which (55%) resulted in infant deaths. In the i-AVB group, there were 40/45 (88.9%) live births and 1/40 (2.5%) infant death; 36 (90%) babies required a permanent pacemaker. The only factor predictive of postnatal death was the presence of CHD (5/9 vs 1/39 or 48.7 [3.6; 1457.7], p < 0.001). Nineteen fetuses (40.5%) with i-AVB received steroids in utero. No difference in outcome was found between the AVB treated in utero versus the no-treatment group in terms of permanent pacemaker placement, postnatal death or development of dilated cardiomyopathy. CONCLUSION: The most important prognostic factor for congenital AVB is the association with CHD. In utero treatment remains questionable.

RESUMEN

OBJECTIVES: The aim of this study was to investigate whether the quadrivalent human papillomavirus (HPV) vaccine Gardasil is associated with a change in the risk of autoimmune disorders (ADs) in young female subjects. DESIGN: Systematic case-control study of incident ADs associated with quadrivalent HPV vaccination in young women across France. PARTICIPANTS AND SETTING: A total of 113 specialised centres recruited (from December 2007 to April 2011) females aged 14-26 years with incident cases of six types of ADs: idiopathic thrombocytopenic purpura (ITP), central demyelination/multiple sclerosis (MS), Guillain-Barré syndrome, connective tissue disorders (systemic lupus erythematosus, rheumatoid arthritis/juvenile arthritis), type 1 diabetes mellitus and autoimmune thyroiditis. Control subjects matched to cases were recruited from general practice. ANALYSIS: Multivariate conditional logistic regression analysis; factors included age, geographical origin, smoking, alcohol consumption, use of oral contraceptive(s) or vaccine(s) other than Gardasil received within 24 months before the index date and personal/family history of ADs. RESULTS: Overall, 211 definite cases of ADs were matched to 875 controls. The adjusted odds ratio (OR) for any quadrivalent HPV vaccine use was 0.9 [95% confidence interval (CI) 0.5-1.5]. The individual ORs were 1.0 (95% CI 0.4-2.6) for ITP, 0.3 (95% CI 0.1-0.9) for MS, 0.8 (95% CI 0.3-2.4) for connective disorders and 1.2 (95% CI 0.4-3.6) for type 1 diabetes. No exposure to HPV vaccine was observed in cases with either Guillain-Barré syndrome or thyroiditis. CONCLUSIONS: No evidence of an increase in the risk of the studied ADs was observable following vaccination with Gardasil within the time periods studied. There was insufficient statistical power to allow conclusions to be drawn regarding individual ADs.

RESUMEN

Artificial intelligence (AI) using deep learning is revolutionizing several fields, including medicine, with a wide range of applications. Available since the end of 2022, ChatGPT is a conversational AI or "chatbot", using artificial intelligence to dialogue with its users in all fields. Through the example of hydroxychloroquine (HCQ), we discuss its use for patients, clinicians, or researchers, and discuss its performance and limitations, particularly in relation to algorithmic bias. If AI tools using deep learning do not dispense with the expertise and experience of a clinician (at least, for the moment), they have a potential to improve or simplify our daily practice.

RESUMEN

Relapsing polychondritis is a rare systemic disease. It usually begins in middle-aged individuals. This diagnosis is mainly suggested in the presence of chondritis, i.e. inflammatory flares on the cartilage, in particular of the ears, nose or respiratory tract, and more rarely in the presence of other manifestations. The formal diagnosis of relapsing polychondritis cannot be established with certainty before the onset of chondritis, which can sometimes occur several years after the first signs. No laboratory test is specific of relapsing polychondritis, the diagnosis is usually based on clinical evidence and the elimination of differential diagnoses. Relapsing polychondritis is a long-lasting and often unpredictable disease, evolving in the form of relapses interspersed with periods of remission that can be very prolonged. Its management is not codified and depends on the nature of the patient's symptoms and association or not with myelodysplasia/vacuoles, E1 enzyme, X linked, autoinflammatory, somatic (VEXAS). Some minor forms can be treated with non-steroidal anti-inflammatory drugs, or a short course of corticosteroids with possibly a background treatment of colchicine. However, the treatment strategy is often based on the lowest possible dosage of corticosteroids combined with background treatment with conventional immunosuppressants (e.g. methotrexate, azathioprine, mycophenolate mofetil, rarely cyclophosphamide) or targeted therapies. Specific strategies are required if relapsing polychondritis is associated with myelodysplasia/VEXAS. Forms limited to the cartilage of the nose or ears have a good prognosis. Involvement of the cartilage of the respiratory tract, cardiovascular involvement, and association with myelodysplasia/VEXAS (more frequent in men over 50years of age) are detrimental to the prognosis of the disease.

RESUMEN

Antiphospholipid syndrome (APS) is a chronic autoimmune disease involving vascular thrombosis and/or obstetric morbidity and persistent antibodies to phospholipids or certain phospholipid-associated proteins. It is a rare condition in adults and even rarer in children. The diagnosis of APS can be facilitated by the use of classification criteria based on a combination of clinical and biological features. APS may be rapidly progressive with multiple, often synchronous thromboses, resulting in life-threatening multiple organ failure. This form is known as "catastrophic antiphospholipid syndrome" (CAPS). It may be primary or associated with systemic lupus erythematosus (associated APS) and in very rare cases with other systemic autoimmune diseases. General practitioners and paediatricians may encounter APS in patients with one or more vascular thromboses. Because APS is so rare and difficult to diagnosis (risk of overdiagnosis) any suspected case should be confirmed rapidly and sometimes urgently by an APS specialist. First-line treatment of thrombotic events in APS includes heparin followed by long-term anticoagulation with a VKA, usually warfarin. Except in the specific case of stroke, anticoagulants should be started as early as possible. Any temporary discontinuation of anticoagulants is associated with a high risk of thrombosis in APS. A reference/competence centre specialised in autoimmune diseases must be urgently consulted for the therapeutic management of CAPS.

RESUMEN

OBJECTIVE: To assess the factors influencing the efficacy of 2 injections of a pandemic 2009 influenza A (H1N1) vaccine in patients with systemic lupus erythematosus (SLE). METHODS: We conducted a single-center, observational prospective study of 111 patients who were vaccinated with a monovalent, inactivated, nonadjuvanted, split-virus vaccine during December 2009 and January 2010 and received a second dose of vaccine 3 weeks later. The antibody response was evaluated using the hemagglutination inhibition assay according to the guidelines recommended for the pandemic vaccine, consisting of 3 immunogenicity criteria (i.e., a seroprotection rate of 70%, a seroconversion rate of 40%, and a geometric mean ratio [GMR] of 2.5). RESULTS: The 3 immunogenicity criteria were met on day 42 (seroprotection rate 80.0% [95% confidence interval (95% CI) 72.5-87.5%], seroconversion rate 71.8% [95% CI 63.4-80.2%], and GMR 10.3 [95% CI 2.9-14.2]), while only 2 criteria were met on day 21 (seroprotection rate 66.7% [95% CI 57.9-75.4%], seroconversion rate 60.4% [95% CI 51.3-69.5%], and GMR 8.5 [95% CI 3.2-12.0]). The vaccine was well tolerated. Disease activity, assessed by the Safety of Estrogens in Lupus Erythematosus National Assessment version of the SLE Disease Activity Index, the British Isles Lupus Assessment Group score, and the Systemic Lupus Activity Questionnaire, did not increase. In the multivariate analysis, vaccination failure was significantly associated with immunosuppressive treatment or a lymphocyte count of ≤ 1.0 × 109/liter. The second injection significantly increased the immunogenicity in these subgroups, but not high enough to fulfill the seroprotection criterion in patients receiving immunosuppressive treatment. CONCLUSION: Our findings indicate that the efficacy of the vaccine was impaired in patients who were receiving immunosuppressive drugs or who had lymphopenia. A second injection increased vaccine immunogenicity without reaching all efficacy criteria for a pandemic vaccine in patients receiving an immunosuppressive agent. These results open possibilities for improving anti-influenza vaccination in SLE.

RESUMEN

Cardiac involvement in systemic lupus (SL) and antiphospholipid syndrome (APS) can be due to variables and involve different presentations. Pericarditis is the most common lupus manifestation and occurs in 16% to 25% of patients. While corticosteroids are usually very effective, colchicine may avoid steroids and prevent relapse. Myocarditis during SL is rare and often inaugural. They may manifest as chest pain, acute heart failure, arrhythmias or conduction disturbances, and may progress to dilated cardiomyopathy and/or permanent heart failure. Their prognosis is however generally good, even in the absence of treatment with cyclophosphamide for the less serious forms. Finally, coronary involvement in SL is most often due to atherosclerotic, thrombotic origin (generally in the context of associated APS), and exceptionally explained by coronary vasculitis. During APS, valve disease is frequent and usually asymptomatic. Thrombotic damage can be (1) coronary, typically manifesting as a myocardial infarction in a young subject with healthy coronary arteries, (2) much more rarely intracardiac, or (3) microcirculatory, generally as part of a catastrophic antiphospholipid syndrome (CAPS) leading to a multiorgan failure. Finally, iatrogenic cardiac manifestations can exceptionally be seen during treatment with cyclophosphamide or antimalarials characterized by conduction disorders and/or heart failure.

RESUMEN

INTRODUCTION: In France, at the end of the sixth year of medical studies, students take a national ranking examination including progressive clinical case-based multiple-choice questions (MCQs). We aimed to evaluate the ability of these MCQs for testing higher-order thinking more than knowledge recall, and to identify their characteristics associated with success and discrimination. METHODS: We analysed the 72 progressive clinical cases taken by the students in the years 2016-2019, through an online platform. RESULTS: A total of 72 progressive clinical cases (18 for each of the 4 studied years), corresponding to 1059 questions, were analysed. Most of the clinical cases (n=43, 60%) had 15 questions. Clinical questions represented 89% of all questions, whereas basic sciences questions accounted for 9%. The most frequent medical subspecialties were internal medicine (n=90, 8%) and infectious diseases (n=88, 8%). The most frequent question types concerned therapeutics (26%), exams (19%), diagnosis (14%), and semiology (13%). Level 2 questions ("understand and apply") accounted for 59% of all questions according to the Bloom's taxonomy. The level of Bloom's taxonomy significantly changed over time with a decreasing number of level 1 questions ("remember") (P=0.04). We also analysed the results of the students among 853 questions of training ECNi. Success and discrimination significantly decreased when the number of correct answers increased (P<0.0001 both). The success, discrimination, mean score, and mean number of discrepancies did not differ according to the diagnosis, exam, imaging, semiology, or therapeutic type of questions. CONCLUSION: Progressive clinical case-based MCQs represent an innovative way to evaluate undergraduate students.

RESUMEN

INTRODUCTION: This case report signifies the need to systemically assess antimalarial toxicity in those undergoing long-term treatment. CASE REPORT: A 59-year-old man with a history of ischemic-labeled heart disease revealed by conduction disorders and cutaneous lupus treated initially with hydroxychloroquine followed by chloroquine consulted for asthenia and weight loss. Clinically, he had a muscular atrophy, a motor deficit, and an abolition of the osteo-tendinous reflexes in the lower limbs. Adverse drug effects of the antimalarial therapy were suspected-specifically, muscular and cardiac toxicity. The diagnosis was confirmed with a muscle biopsy, which showed typical and florid vacuolar myopathy. Cessation of the drug resulted in a slow regression of symptoms. CONCLUSION: Cardiac and muscular toxicity related to antimalarials are rare and sometimes fatal; thus, they must be systematically assessed in a patient with several years of exposure. A muscle biopsy could be sufficient to allow for the diagnosis.

RESUMEN

INTRODUCTION: Patients with sickle cell trait (SCT) are commonly considered as asymptomatic carriers. However, some clinical manifestations may occur. METHODS: Here we present a retrospective descriptive study about SCT subjects with at least one complication diagnosed in a sickle cell disease referral center, in Paris, between 2008 and 2019. We also performed a literature review on the complications of SCT subjects. RESULTS: Six patients (between 19 and 65 years old) were included. SCT was already known only for 4 of them at the time of the complication. Four patients presented with a splenic infarct after a stay in high altitude or a plane trip, one of them was associated with papillary necrosis; one patient had isolated papillary necrosis, and the last one had splenic sequestration. These complications happened for most of them after exposure to an unusual situation of hypoxia or deshydratation. Five out of 6 patients had a marked elevated C reactive protein. CONCLUSION: SCT may cause acute ischemic complications in a context of prolonged hypoxia or dehydration. The most commonly reported are the splenic infarct and the renal papillary necrosis. A study of hemoglobin should be considered in these clinical situations in patients with compatible ethnic origin.
