Cyclophosphamide vs rituximab for eradicating inhibitors in acquired hemophilia A: A randomized trial in 108 patients

BACKGROUND

Acquired hemophilia A (AHA) is a rare autoimmune disorder due to autoantibodies against Factor VIII, with a high mortality risk. Treatments aim to control bleeding and eradicate antibodies by immunosuppression. International recommendations rely on registers and international expert panels.

METHODS

CREHA, an open-label randomized trial, compared the efficacy and safety of cyclophosphamide and rituximab in association with steroids in patients with newly diagnosed AHA. Participants were treated with 1 mg/kg prednisone daily and randomly assigned to receive either 1.5-2 mg/kg/day cyclophosphamide orally for 6 weeks, or 375 mg/m2 rituximab once weekly for 4 weeks. The primary endpoint was complete remission over 18 months. Secondary endpoints included time to achieve complete remission, relapse occurrence, mortality, infections and bleeding, and severe adverse events.

RESULTS

Recruitment was interrupted because of new treatment recommendations after 108 patients included (58 cyclophosphamide, 50 rituximab). After 18 months, 39 cyclophosphamide patients (67.2 %) and 31 rituximab patients (62.0 %) were in complete remission (OR 1.26; 95 % CI, 0.57 to 2.78). In the poor prognosis group (FVIII < 1 IU/dL, inhibitor titer > 20 BU mL-1), significantly more remissions were observed with cyclophosphamide (22 patients, 78.6 %) than with rituximab (12 patients, 48.0 %; p = 0.02). Relapse rates, deaths, severe infections, and bleeding were similar in the 2 groups. In patients with severe infection, cumulative doses of steroids were significantly higher than in patients without infection (p = 0.03).

CONCLUSION

Cyclophosphamide and rituximab showed similar efficacy and safety. As first line, cyclophosphamide seems preferable, especially in poor prognosis patients, as administered orally and less expensive.

Recurrent (or episodic) fever of unknown origin (FUO) as a variant subgroup of classical FUO: A French multicentre retrospective study of 170 patients

BACKGROUND

Recurrent FUO (fever of unknown origin) is a rare subtype of FUO for which diagnostic procedures are ill-defined and outcome data are lacking.

METHODS

We performed a retrospective multicentre study of patients with recurrent FUO between 1995 and 2018. By multivariate analysis, we identified epidemiological, clinical and prognostic variables independently associated with final diagnosis and mortality.

RESULTS

Of 170 patients, 74 (44%) had a final diagnosis. Being ≥ 65 years of age (OR = 5.2; p < 0.001), contributory history (OR = 10.4; p < 0.001), and abnormal clinical examination (OR = 4.0; p = 0.015) independently increased the likelihood of reaching a diagnosis, whereas lymph node and/or spleen enlargement decreased it (OR = 0.2; p = 0.004). The overall prognosis was good; 58% of patients recovered (70% of those with a diagnosis). Twelve (7%) patients died; patients without a diagnosis had a fatality rate of 2%. Being ≥ 65 years of age (OR = 41.3; p < 0.001) and presence of skin signs (OR = 9.5; p = 0.005) significantly increased the risk of death.

CONCLUSION

This study extends the known yield of recurrent FUO and highlights the importance of repeated complete clinical examinations to discover potential diagnostic clues during follow-up. Moreover, their overall prognosis is excellent.

The oral health situation and treatment need of schoolchildren Afghanistan: a cross-sectional study

AIM

The present study explores the treatment need for dental caries in schoolchildren in Herat, Afghanistan.

METHODS

A convenience sample of 13 schools were selected for the study. All schools were located in the urban areas near Herat and were selected through allocation by the Ministry of Health, which also approved the study protocol. In the schools, classes were allocated by the principal of the school. All the children in the allocated classes were included in the survey. Data collection was performed in the school setting by trained Afghan dentist examiners. To measure caries experience, DMFT/dmft scores were used, counting the number of decayed (measured at both white spot (D≥1) and cavitation level (D≥3), according to WHO criteria), missing and filled teeth.

CONCLUSION

Dental caries is a considerable oral health problem in the study population. The present sample has a high proportion of untreated carious lesions and a very low level of restorative care. Moreover, significant differences were shown in relation to gender and age groups. The present survey results confirm the need for professional operative and preventive oral health care in this region.

French National Diagnostic and Care Protocol for antiphospholipid syndrome in adults and children

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.

Atteintes coronariennes et artérite a cellules géantes : à propos de 2 cas et revue de la littérature

INTRODUCTION

Coronaritis is a rare but serious complication of giant-cell arteritis (GCA), with an estimated prevalence of less than 1%, however difficult to establish, and of early onset.

METHODS

We describe 2 cases of GCA presenting with coronaritis and present a review of the literature on this complication.

RESULTS

The first patient presented with stable angina on common trunk coronaritis with ostial stenosis. Corticosteroid combined with tocilizumab from the outset resulted in improvement. Angioplasty was performed at 6months with good outcome. The second patient presented with asymptomatic tritruncular ostial coronaritis. Corticosteroid allowed clinic-biological improvement of GCA. Two years later, he presented relapse with an acute coronary syndrome, with favorable evolution after angioplasty, increase of corticosteroids and addition of tocilizumab.

CONCLUSION

Patients presented were successfully treated with corticosteroids combined with tocilizumab and angioplasty of their coronary stenoses. Efficacy of tocilizumab in GCA has not been evaluated especially on coronaritis due to the rarity of this complication. Our experience and the cases reported in the literature suggest good results of angioplasty in this indication. Studies with long-term follow-up will be necessary to evaluate the risk of restenosis.

Enhancing educational and vocational recovery in adolescents and young adults with early psychosis through Supported Employment and Education (SEEearly): study protocol for a multicenter randomized controlled trial

BACKGROUND

Psychotic disorders often develop a chronic course with devastating consequences for individuals, families, and societies. Early intervention programs for people in the first 5 years after the initial psychotic episode (early psychosis) can significantly improve the outcome and are therefore strongly recommended in national and international guidelines. However, most early intervention programs still focus on improving symptoms and relapse prevention, rather than targeting educational and vocational recovery. The aim of the present study is to explore the effects of Supported Employment and Education (SEE) following the Individual Placement and Support (IPS) model in people with early psychosis.

METHODS

The SEEearly trial compares treatment as usual (TAU) plus SEE to TAU alone in outpatient psychiatric settings. The study is a six-site, two-arm, single-blinded, superiority randomized controlled trial (RCT). Participants are randomly assigned (1:1) to the intervention or control group. Aiming to recruit 184 participants, with an assumed drop-out rate of 22%, we will be able to detect a 24% difference in the main outcome of employment/education with 90% power. We make assessments at baseline and at 6- and 12-month follow-ups. Outcome data on employment/education, medication, and current psychiatric treatment is obtained monthly through phone based short assessments. The primary outcome is steady participation for at least 50% of the 12-month follow-up in competitive employment and/or mainstream education. Secondary employment outcomes capture length of employment/education, time to first employment/education, monthly wages/educational attainment, and social return on investment (SROI). Secondary non-employment outcomes include subjective quality of life, psychopathology, substance use, relapse, hospitalization, and functional impairment. To be eligible, participants must be between 16 and 35 years, fulfill diagnostic criteria for early psychosis, and be interested in competitive employment and/or mainstream education.

DISCUSSION

In SEEearly, we hypothesize that participants with psychosis, who receive TAU plus SEE, present with better primary and secondary outcomes than participants, who receive TAU alone. Positive results of this study will justify SEE as an evidence-based strategy for clinical routine treatment in people with early psychosis.

TRIAL REGISTRATION

SEEearly was registered nationally and internationally in the German Clinical Trials Register (DRKS; identifier: DRKS00029660) on October 14, 2022.

[No improvement in live birth rate after luteal phase support by GnRH agonist]

OBJECTIVES

To evaluate the impact of adding a GnRH agonist (GnRH-a) in luteal phase support (LPS) on live birth rates in IVF/ICSI in antagonist protocols.

METHODS

In total, 341 IVF/ICSI attempts are analyzed in this retrospective study. Patients were divided into two groups: A f: LPS with progesterone alone (179 attempts) between March 2019 and May 2020; B: LPS with progesterone and an injection of triptorelin (GnRH-a) 0.1mg 6 days after oocyte retrieval (162 attempts) between June 2020 and June 2021. The primary outcome was live birth rate. The secondary outcomes were miscarriage rate, pregnancy rate and ovarian hyperstimulation syndrome rate.

RESULTS

The baseline characteristic are identical between the two groups except the infertility duration (longer in the group B). There was no significant difference between the two groups in live birth rate (24.1% versus 21.2%), pregnancy rate (33.3% versus 28.1%), miscarriage rate (4.9% versus 3.4%) and no increase the SHSO rate. The multivariate regression analysis after adjustment for age, ovarian reserve and infertility duration did not reveal a significant difference in live birth rate between the two groups.

CONCLUSION

In this study, the results showed no statistically significant association with the single injection of a GnRH-a in addition to progesterone on live birth rate in luteal phase support.

The ecological validity of traditional standing and novel bicycle balance and agility tests for predicting performance in mountain bikers

Falls are a common mechanism of injury in mountain biking and may be related to a loss of control of the bicycle. Traditionally, the components of bicycle control (balance and agility) are measured in standing and running, which may not reflect the skills required in mountain biking. In this paper, we present the validity of both traditional standing and novel bicycle-specific balance tests in mountain bikers. Twenty-nine male and female participants completed indoor laboratory tests and an outdoor downhill trail. Participants completed single-leg stance balance, Y-balance test, one static and four dynamic bicycle-specific balance tests, a bicycle agility test, and an outdoor downhill trail. Single-leg stance balance and Y-balance tests with eyes open had poor validity when associated with bicycle control. The static (r ​= ​-0.57, p = 0.001) and four dynamic bicycle balance tests (r ​= ​-0.51 to -0.78, p = 0.005 to 0.0001), and the bicycle agility test (r ​= ​0.87, p < 0.0001) had moderate to strong relationships with the outdoor downhill run. Single-leg stance balance and Y-balance tests with eyes open are not valid measures of performance on a mountain bike, and should not be used to assess these populations. Our novel bicycle balance tests have adequate validity to be used as measures of performance in mountain bikers.

ShcA promotes chondrocyte hypertrophic commitment and osteoarthritis in mice through RunX2 nuclear translocation and YAP1 inactivation

OBJECTIVE

Chondrocyte hypertrophic differentiation, a key process in endochondral ossification, is also a feature of osteoarthritis leading to cartilage destruction. Here we investigated the role of the adaptor protein Src homology and Collagen A (ShcA) in chondrocyte differentiation and osteoarthritis.

METHODS

Mice ablated for ShcA in osteochondroprogenitor cells were generated by crossing mice carrying the Twist2-Cre transgene with ShcA^flox/flox mice. Their phenotype (n = 5 to 14 mice per group) was characterized using histology, immuno-histology and western-blot. To identify the signaling mechanisms involved, in vitro experiments were conducted on wild type and ShcA deficient chondrocytes (isolated from n = 4 to 7 littermates) and the chondroprogenitor cell line ATDC5 (n = 4 independent experiments) using western-blot, cell fractionation and confocal microscopy.

RESULTS

Deletion of ShcA decreases the hypertrophic zone of the growth plate (median between group difference -11.37% [95% confidence interval -17.34 to -8.654]), alters the endochondral ossification process, and leads to dwarfism (3 months old male mice nose-to-anus length -1.48 cm [-1.860 to -1.190]). ShcA promotes ERK1/2 activation, nuclear translocation of RunX2, the master transcription factor for chondrocyte hypertrophy, while maintaining the Runx2 inhibitor, YAP1, in its cytosolic inactive form. This leads to hypertrophic commitment and expression of markers of hypertrophy, such as Collagen X. In addition, loss of ShcA protects from age-related osteoarthritis development in mice (2 years old mice OARSI score -6.67 [-14.25 to -4.000]).

CONCLUSION

This study reveals ShcA as a new player in the control of chondrocyte hypertrophic differentiation and its deletion slows down osteoarthritis development.

OP0280 WEANING OF MAINTENANCE IMMUNOSUPPRESSIVE THERAPY IN LUPUS NEPHRITIS (WIN-Lupus): A MULTICENTER RANDOMIZED CONTROLLED TRIAL

Background

Lupus nephritis (LN) is a frequent complication of systemic lupus erythematosus (SLE). Severe (proliferative) forms of LN are treated with an induction immunosuppressive therapy (IST), followed by a maintenance IST, to target remission and avoid relapses. The optimal duration of maintenance IST for proliferative LN is unknown.

Objectives

The WIN-Lupus trial tested whether IST discontinuation after 2-3 years in proliferative LN was non-inferior to IST continuation for 2 more years.

Methods

WIN-Lupus is an investigator-initiated academic randomized controlled trial, conducted in 28 French centers. Patients on maintenance IST with azathioprine or mycophenolate mofetil for a minimum of 2 years and a maximum of 3 years, and who were taking Hydroxychloroquine, were randomized (1:1) between 2 groups: IST continuation and IST discontinuation. The primary endpoint was the relapse rate of proliferative LN at 24 months. Secondary endpoints were the rate of severe SLE flares, survival without renal relapse or severe flare, adverse events, kidney function, disease activity, corticosteroid exposure, patient-reported outcome and medico-economic impact.

Results

Between 2011 and 2016, 125 patients were screened and 96 were randomized in the trial: 48 in the IST continuation group, 48 in the IST discontinuation group. In the per-protocol population, a relapse of proliferative LN occurred in 5/40 (10.4%) patients with IST continuation, and in 12/44 (25%) patients with IST discontinuation (difference 14.8%, 95%CI [-1.9; 31.5]). Non-inferiority was not demonstrated for relapse rate. Time to renal relapse did not differ between groups (p=0.092). Severe SLE flares (renal or extra-renal) were less frequent in patients with IST continuation compared to IST discontinuation (5/40 vs 14/44 patients, p=0.035). IST discontinuation was associated with lower health-related costs. Adverse events did not differ between groups.

Conclusion

Non-inferiority of maintenance IST discontinuation after 2 to 3 years was not demonstrated for renal relapse. IST discontinuation was associated with a higher risk of severe SLE flare.

Swimrun race, athletes, safety and performance: A brief review

Swimrun was established in Sweden in 2006. In competition athletes alternate between running and swimming multiple times. It has grown from only being hosted in Sweden to now being a global sport. The swimrun race exposes athletes to environments that require a unique set of skills. For example, participants have to negotiate ocean currents and waves. The environmental conditions change between the runs and the swims. Athletes may be exposed to hot temperatures when running in wetsuits (25 ​°C and hotter) and cold water (colder than 16 ​°C) when swimming. This sudden change in environmental conditions imposes a poorly defined physiological stress on the participants. Research on the demands of swimrun is scarce. More research is needed to improve athlete safety during events. Also, research is needed to provide insight into enhancing training methods and performance.

Unexpected involvement of a second rodent species makes impacts of introduced rats more difficult to detect

Rodent predators are implicated in declines of seabird populations, and removing introduced rats, often, but not always, results in the expected conservation gains. Here we investigated the relationship between small mammal (Norway rat, wood mouse and pygmy shrew) abundance and Manx shearwater breeding success on the island of Rum, Scotland, and tested whether localised rodenticide treatments (to control introduced Norway rats) increased Manx shearwater breeding success. We found that Manx shearwater breeding success was negatively correlated with late summer indices of abundance for rats and mice, but not shrews. On its own, rat activity was a poor predictor of Manx shearwater breeding success. Rat activity increased during the shearwater breeding season in untreated areas but was supressed in areas treated with rodenticides. Levels of mouse (and shrew) activity increased in areas treated with rodenticides (likely in response to lower levels of rat activity) and Manx shearwater breeding success was unchanged in treated areas (p < 0.1). The results suggest that, unexpectedly, negative effects from wood mice can substitute those of Norway rats and that both species contributed to negative impacts on Manx shearwaters. Impacts were intermittent however, and further research is needed to characterise rodent population trends and assess the long-term risks to this seabird colony. The results have implications for conservation practitioners planning rat control programmes on islands where multiple rodent species are present.

Behavioural, physical, and psychological predictors of cortisol and C-reactive protein in breast cancer survivors: A longitudinal study

Background

Breast cancer survivors (BCS) can exhibit a dysregulation of cortisol and elevated C-reactive protein (CRP) levels post-treatment, which increase the risk of diverse health outcomes. Certain behavioural, physical, and psychological variables may help to predict cortisol and CRP levels post-treatment. The aims of this study were to: (1) describe naturally occurring changes in absolute diurnal cortisol and CRP levels over a period of 1.5 years post-treatment among BCS, (2) assess if absolute diurnal cortisol and CRP levels change in tandem, and (3) assess behavioural, physical, and psychological variables as predictors of absolute diurnal cortisol levels and CRP levels.

Methods

Capillary blood and saliva samples were collected from 201 BCS, on average, 3.5 months post-treatment (T1) and again 3, 6, 9, and 12 months later (T2−T5). At each time point, five saliva samples were collected on two nonconsecutive days: at awakening, 30 ​min after awakening, 2:00 p.m., 4:00 p.m., and at bedtime. At each time point, participants also completed self-report questionnaires and wore an accelerometer for seven consecutive days. Data were analyzed using multilevel modeling.

Results

Absolute diurnal cortisol levels did not change significantly over time. CRP levels decreased across time points (B_linear ​= ​−0.31, p ​= ​.01), though the rate of decrease slowed over time (B_quadratic ​= ​0.05, p ​= ​.03). Generally, greater sedentary time predicted higher overall absolute diurnal cortisol levels (B ​< ​0.01, p ​= ​.01); whereas higher physical activity (B ​= ​−0.004, p ​< ​.01), lower body mass index (B ​= ​0.10, p ​< ​.01), and lower health- and cancer-related stress (B ​= ​0.24, p ​= ​.04) predicted lower overall CRP levels. Also, lower absolute diurnal cortisol levels were evident when participants engaged in more sedentary time, as compared to their own average sedentary time (B ​= ​−0.01, p ​< ​.01).

Conclusions

Results offer insight into the nature of change in diurnal cortisol and CRP levels among BCS from treatment completion onwards and offer clinical implications. Helping BCS manage their weight, reduce stress, increase physical activity participation, and decrease sedentary time as soon as possible after treatment may help to reduce physiological dysregulations, thereby lowering the risk of adverse health outcomes in this population. Further research investigating specific intervention parameters such as type, context, frequency, and intensity are warranted for the development of the most optimal interventions.

Activités de recours et de recherche d’un service de Médecine Interne : une place pour la télémédecine, au-delà de la pandémie COVID-19 ?

Introduction

Les services de Médecine Interne mènent une importante activité de recours expert et de recherche, grevée par plusieurs obstacles. L’activité d’avis spécialisés est chronophage, non valorisée, et limitée par l’impossibilité d’échanger simplement les éléments du dossier médical. L’activité de recherche clinique est limitée par la fréquence des visites protocolaires. L’objectif de ce travail est de déterminer si la télémédecine (TLM) peut contribuer à résoudre ces difficultés.

Patients et méthodes

Concernant l’activité de recours, nous avons demandé aux médecins de déclarer les avis donnés à l’aide d’un formulaire standardisé, afin de déterminer s’ils validaient les critères de téléconsultation (TLC) ou de télé-expertise (TLE). Concernant l’activité de recherche, nous avons remis aux investigateurs et à 50 patients un questionnaire sur l’acceptabilité de TLC protocolaires.

Résultats

Concernant l’activité de recours, on dénombrait 120 avis (soit 21 h) hebdomadaires, dont 29 % aux patients et 69 % à des médecins. Soixante et un pour cent des avis aux patients validaient les critères de TLC ; 18 % des avis aux médecins ceux de TLE. Concernant l’activité de recherche, 70 % des investigateurs considéraient la fréquence des visites comme limitant les inclusions ; près de la moitié des patients serait favorable au recours à des TLC à la place (40 %) ou en plus (56 %) des visites présentielles. En termes de facturation, la TLM représente un revenu potentiel de 300 € hebdomadaires pour le TLE et 616€ hebdomadaires pour le TLC.

Conclusion

Si le recours à la TLM comme procédure dégradée au présentiel s’est démocratisé avec la pandémie, les solutions qu’elle apporte aux difficultés rencontrées dans les activités d’avis et de recherche peuvent contribuer à intégrer pleinement son usage dans le suivi standard des patients. Si tel était le cas, on pourrait tout à fait imaginer avec ce budget (47 632 €/an) pouvoir financer un praticien hospitalier supplémentaire à temps partiel.

POS0724 GENDER DIFFERENCES IN THROMBOTIC PRIMARY ANTIPHOSPHOLIPID SYNDROME IN A LARGE COHORT OF PATIENTS FROM FOUR EUROPEAN CENTERS

Background:

Autoimmune diseases occur more frequently in females and their course and severity can be affected by gender. Antiphospholipid syndrome (APS) is a systemic autoimmune disorder in which antiphospholipid antibodies (aPL) exert a pathogenic role resulting in vascular thrombosis and/or pregnancy morbidities. Data about gender differences in thrombotic APS (t-APS) are still scarce1,2.

Objectives:

To evaluate the differences in frequency, disease expression and severity between females and males affected by primary t-APS.

Methods:

Retrospective study enrolling subjects with a formal diagnosis of primary APS (Miyakis 2006) with vascular thrombosis at onset. Women who presented with obstetric events as first aPL-related manifestation were excluded. All the patients were followed from 1967 to 2019 in four European centers: three French centers and one Italian center.

Results:

The study included 433 patients (68% females, 32% males). Median age at t-APS onset [31 (24-46) vs 41 (29-53) years, p<0.001] and at diagnosis [34 (27-50) vs 46 (34-57) years, p<0.001] was significantly lower in females.

The most common presenting manifestations were venous thrombosis (60%) followed by arterial events (37%) and catastrophic APS (3%). Venous events were more frequent in women as compared to men (64% vs 51% p:0.012 OR:1.7 [1.1-2.5]). Sites of venous thrombosis included: limbs (35%), pulmonary (17%), cerebral (3%), portal and inferior cava (2%) and retinal (1%) veins, without gender differences. The arterial events were more frequent among men (43% vs 34% p:0.053). Strokes (27%) and myocardial infarctions (4%) were the most frequent manifestations, followed by thrombosis of limbs (2%), retina (2%) and abdominal organs (1%). Noteworthy, only men presented with visceral ischemia.

During the follow-up, new thrombosis occurred in 41% of patients (179/433). 33% out of them had at least two episodes and these occurred especially among males (22% vs 10% p:0.001 OR:2.5 [1.3-4.8]). New events were mostly of the same type, but ⅓ of patients presented a switch from venous to arterial side and viceversa, with no gender differences.

Complete aPL profile was available in 357 subjects: 33% had single aPL positivity, 24% double positivity and 43% triple positivity, with no differences between women and men. About 80% of the patients had a concomitant risk factor (RF) for thrombosis. Established cardiovascular RFs were more represented among men as shown in table 1. In women, estrogenic exposure was the main RFs, present in almost 40% of them.

Conclusion:

This gender-oriented analysis of patients with primary t-APS showed that women had the first vascular event at a younger age and mostly on the venous side, while men presented mainly with arterial events, later in life and suffered from more recurrent events. No differences were observed in the distribution of the aPL profile. The different frequency of arterial and venous events in the two groups could be attributed mainly to the presence of additional RFs rather than to biological gender-specific issues. However, it should be underlined that some RFs, such as the use of estrogens or classic cardiovascular RFs, are exclusive or more represented in one gender rather than the other, making it difficult to assess the link of causality between gender and manifestations of t-APS.

[Genitourinary menopause syndrome. Postmenopausal women management: CNGOF and GEMVi clinical practice guidelines]

INTRODUCTION

Genitourinary menopause syndrome (SGUM) is defined as a set of symptoms associated with a decrease of estrogen and other sexual steroids during menopause. The main symptoms are vulvovaginal (dryness, burning, itching), sexual (dyspareunia), and urinary (urinary infections, pollakiuria, nycturia, pain, urinary incontinence by urgenturia). SGUM leads to an alteration of the quality of life, and affects especially women's sexuality.

OBJECTIVE

The objective of this review was to elaborate guidelines for clinical practice regarding the management of SGUM in postmenopausal women, and in particular, in women with a history of breast cancer, treated or not with hormone therapy.

MATERIALS AND METHODS

A systematic review of the literature on SGUM management was conducted on Pubmed, Medline and Cochrane Library. Recommendations from international scholarly societies were also taken into account: International Menopause Society (IMS) https://www.imsociety.org, The North American Menopause Society (NAMS) https://www.menopause.org, Canadian Menopause Society https://www.sigmamenopause.com, European Menopause and Andropause Society (EMAS) https://www.emas-online.org, International Society for the Study of Women's Sexual Health (ISSWSH) https://www.isswsh.org.

RESULTS

Vaginal use of lubricants, moisturizers and hyaluronic acid improves the symptoms of SGUM and may be offered to all patients. For postmenopausal women, local estrogen will be preferred to the oral route because of their safety and efficacy on all symptoms of SGUM during low-dose use. Prasterone is a local treatment that can be proposed as an effective alternative for the management of dyspareunia and sexual function disorder. Current data on oral testosterone, tibolone, oral or transdermal DHEA and herbal medicine are currently limited. Ospemifène, which has shown a significant improvement in sexual symptoms, is not currently marketed in France. In the particular case of women with a history of breast cancer, non-hormonal regimens are a first-line therapy. Current data on the risk of breast cancer recurrence when administering low-dose local estrogen are reassuring but do not support a conclusion that this treatment is safe.

CONCLUSION

SGUM is a common symptom that can affect the quality of life of postmenopausal women. A treatment should be systematically proposed. Local non-hormonal treatment may be offered in all women. Local low-dose estrogen therapy and Prasterone has shown an interest in the management of symptoms. In women before a history of breast cancer, local non-hormonal treatment should be offered first-line. The safety of low-dose local estrogen therapy and Prasterone cannot be established at this time. Other alternatives exist but are not currently recommended in France due to lack of data.

Cognitive and emotional empathy in individuals at clinical high risk of psychosis

BACKGROUND

Impairments of social cognition are considered core features of schizophrenia and are established predictors of social functioning. However, affective aspects of social cognition including empathy have far less been studied than its cognitive dimensions. The role of empathy in the development of schizophrenia remains largely elusive.

METHODS

Emotional and cognitive empathy were investigated in large sample of 120 individuals at Clinical High Risk of Psychosis (CHR-P) and compared with 50 patients with schizophrenia and 50 healthy controls. A behavioral empathy assessment, the Multifaceted Empathy Test, was implemented, and associations of empathy with cognition, social functioning, and symptoms were determined.

RESULTS

Our findings demonstrated significant reductions of emotional empathy in individuals at CHR-P, while cognitive empathy appeared intact. Only individuals with schizophrenia showed significantly reduced scores of cognitive empathy compared to healthy controls and individuals at CHR-P. Individuals at CHR-P were characterized by significantly lower scores of emotional empathy and unspecific arousal for both positive and negative affective valences compared to matched healthy controls and patients with schizophrenia. Results also indicated a correlation of lower scores of emotional empathy and arousal with higher scores of prodromal symptoms.

CONCLUSION

Findings suggest that the tendency to 'feel with' an interaction partner is reduced in individuals at CHR-P. Altered emotional reactivity may represent an additional, early vulnerability marker, even if cognitive mentalizing is grossly unimpaired in the prodromal stage. Different mechanisms might contribute to reductions of cognitive and emotional empathy in different stages of non-affective psychotic disorders and should be further explored.

Raising rare disease awareness using red flags, role play simulation and patient educators: results of a novel educational workshop on Raynaud phenomenon and systemic sclerosis

BACKGROUND

As lack of awareness of rare diseases (RDs) among healthcare professionals results in delayed diagnoses, there is a need for a more efficient approach to RD training during academic education. We designed an experimental workshop that used role-play simulation with patient educators and focused on teaching "red flags" that should raise the suspicion of an RD when faced with a patient with frequently encountered symptoms. Our objective was to report our experience, and to assess the improvement in learners' knowledge and the satisfaction levels of the participants.

RESULTS

The workshop consisted of 2 simulated consultations that both started with the same frequent symptom (Raynaud phenomenon, RP) but led to different diagnoses: a frequent condition (idiopathic RP) and an RD (systemic sclerosis, SSc). In the second simulated consultation, the role of the patient was played by a patient educator with SSc. By juxtaposing 2 seemingly similar situations, the training particularly highlighted the elements that help differentiate SSc from idiopathic RP. When answering a clinical case exam about RP and SSc, students that had participated in the workshop had a higher mean mark than those who had not (14 ± 3.7 vs 9.6 ± 5.5 points out of 20, p = 0.001). Participants mostly felt "very satisfied" with this training (94%), and "more comfortable" about managing idiopathic RP and SSc (100%). They considered the workshop "not very stressful" and "very formative" (both 71%). When asked about the strengths of this training, they mentioned the benefits of being put in an immersive situation, allowing a better acquisition of practical skills and a more interactive exchange with teachers, as well as the confrontation with a real patient, leading to a better retention of semiological findings and associating a relational component with this experience.

CONCLUSIONS

Through the use of innovative educational methods, such as role-play simulation and patient educators, and by focusing on teaching "red flags", our workshop successfully improved RP and SSc learning in a way that satisfied students. By modifying the workshop's scenarios, its template can readily be applied to other clinical situations, making it an interesting tool to teach other RDs.

An investigation into socio-demographic-, health-, and cancer-related factors associated with cortisol and C-reactive protein levels in breast cancer survivors: a longitudinal study

BACKGROUND

Breast cancer survivors (BCS) may exhibit dysregulated patterns of cortisol and C-reactive protein (CRP). The aims of this study were to describe BCS' cortisol and CRP levels over a 1-year period after treatment, and assess how levels relate to socio-demographic- (age, education level, marital status), health- (body mass index [BMI] category, menopausal status), and cancer-related factors (cancer stage, chemotherapy exposure, time since diagnosis).

METHODS

Participants (N = 201) provided data at 3 months post-treatment (T1) and again 3, 6, 9, and 12 months later (T2-T5). At T1, participants completed self-report questionnaires and had their weight and height measured by a trained technician. At T1-T5, they provided five saliva samples at awakening, 30 min after awakening, 2:00 pm, 4:00 pm, and before bedtime on two nonconsecutive days to measure diurnal cortisol, and provided capillary whole blood to measure CRP. Data were analyzed using repeated-measure analyses of variance (ANOVAs) and mixed-design ANOVAs.

RESULTS

Diurnal cortisol and CRP levels fluctuated over time. In univariate models, older age and post-menopausal status were associated with higher cortisol and CRP levels, higher cancer stage and chemotherapy were associated with lower cortisol levels, and higher BMI category was associated with higher CRP levels. In adjusted models, age was no longer associated with CRP levels and shorter time since diagnosis was significantly associated with higher CRP levels.

CONCLUSIONS

Socio-demographic-, health-, and cancer-related factors may help identify BCS at risk of physiological dysregulation who need intervention. Identifying modifiable factors associated with cortisol and CRP will inform cancer care interventions.

AB1273 TEACHING RARE DISEASES THROUGH ROLE PLAY: RESULTS OF AN EXPERIMENTAL WORKSHOP ON RAYNAUD PHENOMENON

Background:

Systemic autoimmune diseases are mostly taught through theoretical lectures, which do not allow for the acquisition of physical examination skills and semiologic confrontation.

Objectives:

We report herein the results of a pilot experiment using role-play to teach how to manage patients with Raynaud phenomenon (RP).

Methods:

We developed a workshop that consisted of two 30-minute OSCE (Objective and Structured Clinical Examination) stations. Students were divided into groups of 4 to 5 persons. On each station, 2 students were actors and 2 were observers. After a short briefing, students played a 15-minute scenario and then had a 15-minute debriefing.

The first station simulated the case of a 26-year old woman referred for suspected RP. Students were instructed to perform clinical history taking and physical examination of the patient, formulated relevant diagnosis hypotheses and prescribe any additional necessary exams. Students had to suspect the diagnosis of idiopathic RP. The simulated patient was played by a trained facilitator with expertise on RP.

The second station simulated the case of a 56-year-old woman referred for RP complicated by digital ulcers. Students received the same instructions as before. They had to suspect the diagnosis of systemic sclerosis. The patient role was held by a real patient with systemic sclerosis, followed by the physician who was supervising the station, who had received prior training and who agreed to participate in this training.

At the end of the workshop, the students had to complete a satisfaction questionnaire.

Results:

A total of 21 students participated in the workshop and 17 completed the survey. The students were “very satisfied” (Likert 4/4) of this training in 94%. They considered this workshop “not very stressful” (Likert 2/4) and “very formative” (Likert 4/4) in 71%, but “a little short” (Likert 2/4) in 88%. After taking this training, all students felt “a little” (Likert 3/4, 24%) or “much more comfortable” (Likert 4/4, 76%) to manage patients with idiopathic RP; and “a little” (Likert 3/4, 65%) or “much more comfortable” (Likert 4/4, 35%) to manage patients with systemic sclerosis. All would recommend this workshop to other students.

When asked about the strengths of this training, the students mentioned the benefits of being put in an immersive situation, which allowed for a better acquisition of practical skills (especially physical examination) and a more interactive exchange with teachers; as well as the confrontation with a real patient, which allowed for a better retention of semiologic findings and associated a relational component to this experience. The main weak points reported were its short duration and the stress induced by being observed during the simulation.

Conclusion:

This workshop suggests the interest and feasibility on a small group of students of a rare diseases awareness workshop using role-play. The evaluation of its pedagogical efficiency and its generalization on large student promotions are being considered.

SAT0244 PROGNOSIS OF LARGE VESSEL INVOLVEMENT IN LARGE VESSEL VASCULITIS

Background:

Giant cell arteritis (GCA) and Takayasu arteritis (TAK) are the two main forms of large vessels vasculitis (LVV). Vessel inflammation leads to aneurysms, wall thickening, stenosis, and, in some cases, complete occlusion of the artery. Due to the wide variation in the course of LVV, predicting outcome is challenging. To our knowledge, data regarding prognosis factors of LVI in LVV patients and comparison of outcome of LVI in GCA and TAK are lacking. An early identification of patients with higher mortality could help to prevent deaths and vascular complications.

Objectives:

To assess prognosis factors and outcome of large vessel involvement (LVI) in large vessels vasculitis (LVV) patients.

Methods:

Retrospective multicenter study of characteristics and outcomes of 417 patients with LVI including 299 Takayasu arteritis (TAK) and 118 Giant cell arteritis (GCA-LVI) were analyzed. Logistic regression analysis assessed prognosis factors in LVV patients. Outcome of LVI among TAK and GCA-LVI patients (ischemic complications, aneurysms complications, relapses and revascularization) were assessed.

Results:

In multivariable analysis, stroke/transient ischemic attack [HR: 3.63 (1.46 - 9.04), p=0.006] was independently associated with vascular complications in LVV. The 10-years aneurysm free survival was significantly lower [67% (48 – 93) vs 89% (84 – 95), p=0.02] in GCA-LVI compare to TAK patients. The 5-years relapse free survival was significantly lower [47% (37 – 60) vs 69% (63 – 75), p<0.001,] in GCA-LVI compare to TAK patients. The 10-years revascularization free survival was significantly lower [55% (48 – 64) vs 76% (59 – 99), p<0.001] in TAK compare to GCA-LVI patients. After a median follow-up of 5 years, 16 (5.4%) TAK and 7 (5.9%) GCA-LVI patients died, mainly of aneurysm (26%) and ischemic complications (26%).

Conclusion:

This large nationwide cohort of LVI provided prognosis factors of vascular complications in LVV patients. TAK and GCA-LVI have different long-term outcome in term of aneurysm development, relapse and revascularization.

AB0510 INFLIXIMAB IS AN EFFECTIVE GLUCOCORTICOID-SPARING TREATMENT FOR TAKAYASU ARTERITIS: RESULTS OF A MULTICENTER OPEN-LABEL PROSPECTIVE STUDY

Background:

Approximately half of patients with Takayasu Arteritis (TA) have glucocorticoid (GC)-dependency and require the addition of a second-line immunosuppressive treatment.

Objectives:

Here, we conducted a multicenter open-label prospective cohort study to assess the efficacy and safety of infliximab originator as a GC-sparing agent in TA.

Methods:

A temporary recommendation for use for infliximab in refractory TA was approved by the French National Drug Authorities (April 2014). Infliximab was administered to patients in case of disease activity with a NIH score ≥2 despite conventional therapy. Data regarding patient’s clinical, laboratory, imaging and treatments were obtained at baseline, and at each following visit until last visit (October 2017). TA activity was evaluated according to NIH criteria and GC requirement throughout the study.

Results:

Twenty-three patients were enrolled, including 19 female. The median age at inclusion was 33 years (Interquartile range, IQR: 23-44 years). At baseline, 17 (74%) patients were treated with GCs, at a median dose of 10 mg/day (IQR: 0-21) of prednisone-equivalent. After a median follow-up of 36.9 months (IQR: 10-58.7), improvement of ≥1 NIH criterion of TA activity was achieved for 14/22 (64%) patients. The median GC dose was 8 mg/day (IQR: 7-10) at 6 months; 5 mg/day (IQR: 0-8) at 12 months and 0 mg/day (IQR: 0-5) at 36 months of follow-up. Overall, infliximab originator had a significant GC-sparing effect between baseline and last follow-up (p=0.009).

Conclusion:

This multicenter open-label cohort study suggests that infliximab originator is an effective GC-sparing treatment for TA refractory to conventional therapy.

Psychiatric disorders among migrants in Germany: prevalence in a psychiatric clinic and implications for services and research

Past studies examining the prevalence of psychiatric disorders among migrants have described a higher rate of schizophrenia, whereas the only major German study found a lower rate. Considering the changed composition of migrants today, a new assessment has become necessary. All admission records of migrants to a psychiatric clinic in 1993 and 1994 were assessed for diagnosis, symptomatology and treatment. Two hundred sixty-three migrant admissions, 8.4% of total admissions, were assessed. Of these 41.4% received a diagnosis of a schizophrenic disorder, significantly more than other clinic patients. The mean age at admission was 33.8 years, at onset of illness 28.6 years and at time of migration 20.3 years. Only 7.9% were mentally ill at the time of migration. Of those with psychotic and depressive symptoms at admission, 70% received a diagnosis of a schizophrenic disorder and 78% were treated with antipsychotics. Antidepressants were prescribed only to 47% of those with a diagnosis of a depressive disorder and only 33% of those with depressive and no psychotic symptoms. An underrepresentation of migrants shows differences in the use of psychiatric services. The higher rate of schizophrenia may be due to misdiagnosis, an artifactual effect of underrepresentation of other disorders or an actual higher rate among migrants. The reluctance to use antidepressants underlines the necessity of training, so as not to withhold treatment options due to cultural barriers.

Better care for less money: cost-effectiveness of integrated care in multi-episode patients with severe psychosis

OBJECTIVE

To compare cost-effectiveness of integrated care with therapeutic assertive community treatment (IC-TACT) versus standard care (SC) in multiple-episode psychosis.

METHOD

Twelve-month IC-TACT in patients with schizophrenia-spectrum and bipolar I disorders were compared with a historical control group. Primary outcomes were entropy-balanced cost-effectiveness based on mental healthcare costs from a payers' perspective and quality-adjusted life years (QALYs) as a measure of health effects during 12-month follow-up.

RESULTS

At baseline, patients in IC-TACT (n = 214) had significantly higher illness severity and lower functioning than SC (n = 56). Over 12 months, IC-TACT had significantly lower days in inpatient (10.3 ± 20.5 vs. 28.2 ± 44.9; P = 0.005) and day-clinic care (2.6 ± 16.7 vs. 16.4 ± 33.7; P = 0.004) and correspondingly lower costs (€-55 084). Within outpatient care, IC-TACT displayed a higher number of treatment contacts (116.3 ± 45.3 vs. 15.6 ± 6.3) and higher related costs (€+1417). Both resulted in lower total costs in IC-TACT (mean difference = €-13 248 ± 2975, P < 0.001). Adjusted incremental QALYs were significantly higher for IC-TACT versus SC (+0.10 ± 0.37, P = 0.05). The probability of cost-effectiveness of IC-TACT was constantly higher than 99%.

CONCLUSION

IC-TACT was cost-effective compared with SC. The use of prima facies 'costly' TACT teams is highly recommended to improve outcomes and save total cost for patients with severe psychotic disorders.
