Access to care for aging former workers living in an immigrant hostel / Accès aux soins d'une population d'anciens travailleurs immigrés vivant en foyer

The Chibanis represent the population of aging former immigrant workers who arrived in France in the 1970s in order to take up employment. Most of them still live in immigrant hostels, which are not appropriate for an older population. This anthropological study was conducted on Chibanis living in an immigrant hostel in the 15th arrondissement of Marseille. The objectives were to assess the medical, economic, and social characteristics of this population, to understand their access to health care, and to measure their adherence to the prevention actions of an association. 67 Chibanis aged 65 and over were included, with a median age of 77: 91% had access to a general practitioner, and 86.6% had more than two chronic diseases. More than half of the Chibanis complained of dental problems, and 20% complained of ophthalmological problems. Only 32.8% of the Chibanis included agreed to follow-up care with the nurses from the association. The population of Chibanis are isolated geographically from their families, live in poor socio-economic conditions, and often have insufficient medico-social coverage. They must "manage" their chronic diseases, as well as costly health problems such as dental or ophthalmic diseases. Improving care pathways for this population requires us to identify their specificities and all the factors hindering prevention actions.

Les Chibanis ­ "cheveux blancs" en arabe dialectal ­ désignent les anciens travailleurs immigrés arrivés en France dans les années 1970 pour exercer un emploi. Ils vivent encore pour la plupart au sein de foyers construits pour des hommes seuls exerçant une profession et non pour accueillir des hommes en situation de vieillissement. Notre travail anthropologique s'est organisé autour d'une population de Chibanis, vivant dans un foyer dans le 15e arrondissement de Marseille. Les objectifs étaient de mieux connaître cette population d'un point de vue médico-socio-culturel, de connaître les modalités de leur accès aux soins et enfin de connaître leur adhésion aux actions de prévention d'une association. 67 Chibanis ≥65 ans ont été inclus, avec une médiane de l'âge de 77 ans : 91 % déclaraient avoir un médecin traitant, 86,6 % avaient plus de 2 maladies chroniques. Plus de la moitié des Chibanis souffraient de problèmes dentaires et près de 20 % présentaient des problèmes ophtalmologiques. Seuls 32,8 % des Chibanis inclus ont accepté de réaliser un suivi par les infirmiers. La population des Chibanis, isolée géographiquement de leur famille, économiquement précaire et avec une couverture médico-sociale souvent insuffisante, doit « gérer ¼ ses pathologies chroniques, et des problèmes de santé notamment dentaires et ophtalmiques couteux. L'amélioration de leurs parcours de santé nécessite de mieux comprendre leurs spécificités et les divers facteurs qui peuvent entraver les actions de prévention.

Obinutuzumab in Frequently Relapsing and Steroid-Dependent Nephrotic Syndrome in Children.

BACKGROUND: B-cell depletion with rituximab induces sustained remission in children with steroid-dependent or frequently relapsing nephrotic syndrome. However, most patients relapse after B-cell recovery, and some patients do not achieve B-cell depletion. Obinutuzumab is a second-generation anti-CD20 antibody designed to overcome such situations in B-cell malignancies and was recently reported to be safe and effective in other autoimmune diseases affecting the kidneys. METHODS: We retrospectively report 41 children with steroid-dependent or frequently relapsing nephrotic syndrome treated with a single low-dose infusion of obinutuzumab at Robert-Debre Hospital between April 2018 and December 2020. Participants were treated because of rituximab resistance or relapse after rituximab and received a single infusion of 300 mg/1.73 m 2 obinutuzumab with cessation of oral immunosuppressors within 2 months. RESULTS: B-cell depletion was achieved in all participants and lasted a median of 8.3 months (interquartile range, 6.4-11.1), a duration exceeding that for last rituximab treatment. At 12 and 24 months, 92% (38/41) and 68% (28/41) of patients, respectively, were in sustained remission. Mild infusion reactions occurred in five participants (12%) and neutropenia in nine (21%). No significant decrease in IgG level was reported during treatment, and whereas IgM levels decreased in 34 patients (83%), they were normal at last follow-up in 32 (78%). CONCLUSIONS: These results identified low-dose obinituzumab as a promising treatment option in children with steroid-dependent or frequently relapsing nephrotic syndrome, including those resistant to rituximab. The tolerance profile of obinutuzumab was similar to that of rituximab, but hemogram and immunoglobulin levels should be monitored.

[Tagravpa: Help table and grid for identifying the risk of aggravation and early rehospitalization of elderly persons 75 years and older referred to emergency departments and/or hospitalized in care units]. / Tagravpa : Tableau d'aide et grille de repérage du risque d'aggravation et de réhospitalisation précoce des personnes âgées de 75 ans et plus adressées aux urgences et/ou hospitalisées dans les unités de soins.

People aged 75 and over, frail or dependent are the most frequently hospitalized, particularly via the emergency department, and are sometimes readmitted to hospital less than a month after their discharge. Article 70 of the 2012 social security financing act has set up experiments aimed at improving the care pathway for the elderly. In this context, Marseille University Hospital has developed a table of help and grid for identifying the risk of aggravation of the elderly (Tagravpa). Comprising nine medical-psycho-social items, the grid enables the identification of the risk of aggravation to which is associated a score for identifying the risk of early re-hospitalization for the modeling of care pathways. A study was conducted in two departments. In cardiology for readmission at 1 month the results showed a grid positivity threshold of 6 for sensitivity measured at 56,6% (95% CI: 22,7-84,7) and specificity of 61,5% (95% CI: 40,7-79,1). In Emergency Department the results showed a positivity threshold of 4 for sensitivity at 83,3% (95% CI: 57,7-95,6) and specificity at 45,5% (95% CI: 36,8-54,3). This grid, called TAGRAVPA appears as a simple tool for identifying the risk of early re-hospitalization. It is applicable in a hospital environment, whatever the department and allows the initiation of an adapted path for the elderly person hospitalized or returning home from the emergency department.

Tocilizumab versus anakinra in COVID-19: results from propensity score matching.

Background: Tocilizumab and anakinra are anti-interleukin drugs to treat severe coronavirus disease 2019 (COVID-19) refractory to corticosteroids. However, no studies compared the efficacy of tocilizumab versus anakinra to guide the choice of the therapy in clinical practice. We aimed to compare the outcomes of COVID-19 patients treated with tocilizumab or anakinra. Methods: Our retrospective study was conducted in three French university hospitals between February 2021 and February 2022 and included all the consecutive hospitalized patients with a laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection assessed by RT-PCR who were treated with tocilizumab or anakinra. A propensity score matching was performed to minimize confounding effects due to the non-random allocation. Results: Among 235 patients (mean age, 72 years; 60.9% of male patients), the 28-day mortality (29.4% vs. 31.2%, p = 0.76), the in-hospital mortality (31.7% vs. 33.0%, p = 0.83), the high-flow oxygen requirement (17.5% vs. 18.3%, p = 0.86), the intensive care unit admission rate (30.8% vs. 22.2%, p = 0.30), and the mechanical ventilation rate (15.4% vs. 11.1%, p = 0.50) were similar in patients receiving tocilizumab and those receiving anakinra. After propensity score matching, the 28-day mortality (29.1% vs. 30.4%, p = 1) and the rate of high-flow oxygen requirement (10.1% vs. 21.5%, p = 0.081) did not differ between patients receiving tocilizumab or anakinra. Secondary infection rates were similar between the tocilizumab and anakinra groups (6.3% vs. 9.2%, p = 0.44). Conclusion: Our study showed comparable efficacy and safety profiles of tocilizumab and anakinra to treat severe COVID-19.

Quality of life in older French long-term lung cancer survivors: VICAN5 national survey.

OBJECTIVES: This study aimed to describe quality of life (QoL) five years after diagnosis, in a representative sample of lung cancer (LC) survivors, to compare the QoL of survivors aged 70 years or older with that of younger ones, and to identify factors associated with poorer long-term QoL in both age groups. MATERIALS AND METHODS: Our study sample consists of all individuals with a LC diagnosed between January 2010 and December 2011, who participated in the French national survey VICAN 5. RESULTS: A total of 371 participants had LC. At the time of the survey, 21.3% of the participants were 70 years or older. In this older age group, feeling self-conscious about appearance and suspected neuropathic pain were independently associated with physical QoL impairment and lower Post-Traumatic Growth Inventory score, and suspected neuropathic pain was associated with impaired mental QoL. In younger patients, impaired physical QoL was independently associated with male gender, metastatic cancer, suspected neuropathic pain, report of severe after-effects of LC and difficulty breathing at rest in the past 7 days, and impaired mental QoL was independently associated with male gender, impaired ECOG-PS, and anxiety. CONCLUSION: Factors associated with an impaired QoL in LC survivors, varied according to patient age. In both populations, psychological support and adapted physical activity can be offered to improve mental QoL and physical symptomatology. For older survivors with neuropathic pain, analgesic therapies can be discussed to improve long-term QoL.

Biallelic NPR1 loss of function variants are responsible for neonatal systemic hypertension.

BACKGROUND: Early-onset isolated systemic hypertension is a rare condition of unknown genetic origin. Renovascular, renal parenchymal diseases or aortic coarctation are the most common causes of secondary systemic hypertension in younger children and neonates. We investigated the genetic bases of early-onset isolated systemic hypertension. METHODS: Whole-exome sequencing (WES) was followed by variant filtering and Sanger sequencing for validation and familial segregation of selected variants in a large consanguineous family. mRNA expression was performed to evaluate the impact of the predicted pathogenic variant on gene expression. WES or Sanger sequencing was performed in additional unrelated affected individuals. RESULTS: In one consanguineous family with four children presenting with isolated neonatal-onset systemic hypertension, we identified homozygous stop-gain variant in the NPR1 gene (NM_000906.4:c.1159C>T (p.Arg387Ter)) in the affected individuals. This variant leads to a dramatic reduction of NPR1 RNA levels. NPR1 gene analysis of additional families allowed the identification of another family with two affected children carrying homozygous frameshift variant in NPR1 (NM_000906.4:c.175del (p.Val59TrpfsTer8)). CONCLUSION: We show for the first time that biallelic loss of function of NPR1 is responsible for isolated neonatal-onset systemic hypertension in humans, which represents a new autosomal recessive genetic cause of infantile systemic hypertension or cardiogenic shock. This is consistent with studies reporting early-onset systemic hypertension and sudden death in Npr1-deficient mice. NPR1 gene analysis should be therefore investigated in infants with early-onset systemic hypertension with or without cardiogenic shock of unknown origin.

Renal vein thrombosis in neonates: a case series of diagnosis, treatment and childhood kidney function follow-up.

BACKGROUND: Neonatal renal vein thrombosis (NRVT) is a rare condition with little data available. METHODS: We retrospectively analyzed newborns diagnosed with NRVT admitted to 3 pediatric nephrology units in Paris from 2005 to 2020. RESULTS: Twenty-seven patients were analyzed (male = 59%). The median age at diagnosis was 2.5 days (1 - 4.5). Diagnosis was suspected based on at least one of the three cardinal signs of renal vein thrombosis in 93%: flank mass (67%), hematuria (67%) and thrombocytopenia (70%). In all patients, diagnosis was confirmed by ultrasound. All patients had at least one known perinatal risk factor. A prothrombotic risk factor was found in 13 patients (48%). NRVT was unilateral in 70%, involving the left renal vein in 58%. Among 25 treated patients, 19 (76%) received low molecular weight heparin (LMWH) as initial therapy, 2 (8%) received unfractionated heparin and 4 (16%) received fibrinolysis. Median duration of treatment was 8 weeks (4 - 12). Bleeding occurred significantly more often with fibrinolysis than with LMWH/supportive therapy (3 of 4: 75% vs 0 of 4: 0%, p = 0.05). Clot resolution in patients treated with fibrinolysis did not differ significantly from those treated with LMWH/supportive therapy. After a median follow-up of 5.7 years (3 years - 9.9 years), pathological kidney features were observed in 73% of the patients (19 of 26), kidney atrophy in 18 (69%), hypertension in 2 (8%), chronic kidney disease (CKD) in 1 (4%) and proteinuria in 2 (8%). CONCLUSIONS: NRVT remains a challenging condition, which still requires further study because of its associated morbidity.

Pre-Therapeutic Sarcopenia among Cancer Patients: An Up-to-Date Meta-Analysis of Prevalence and Predictive Value during Cancer Treatment.

This study will address the prevalence of pre-therapeutic sarcopenia (PS) and its clinical impact during cancer treatment among adult cancer patients ≥ 18 years of age. A meta-analysis (MA) with random-effect models was performed via a MEDLINE systematic review, according to the PRISMA statement, focusing on articles published before February 2022 that reported observational studies and clinical trials on the prevalence of PS and the following outcomes: overall survival (OS), progression-free survival (PFS), post-operative complications (POC), toxicities (TOX), and nosocomial infections (NI). A total of 65,936 patients (mean age: 45.7-85 y) with various cancer sites and extensions and various treatment modes were included. Mainly defined by CT scan-based loss of muscle mass only, the pooled prevalence of PS was 38.0%. The pooled relative risks were 1.97, 1.76, 2.70, 1.47, and 1.76 for OS, PFS, POC, TOX, and NI, respectively (moderate-to-high heterogeneity, I2: 58-85%). Consensus-based algorithm definitions of sarcopenia, integrating low muscle mass and low levels of muscular strength and/or physical performance, lowered the prevalence (22%) and heterogeneity (I2 < 50%). They also increased the predictive values with RRs ranging from 2.31 (OS) to 3.52 (POC). PS among cancer patients is prevalent and strongly associated with poor outcomes during cancer treatment, especially when considering a consensus-based algorithm approach.

Prevention of aromatase inhibitor-induced bone loss with anti-resorptive therapy in post-menopausal women with early-stage breast cancer.

We assessed if antiresorptive treatment can prevent aromatase inhibitor-induced bone loss in patients with early breast cancer. We observed that patients who did not receive antiresorptive treatment had a 20.8-fold increase in risk of bone loss after 24 months of aromatase inhibitors therapy. PURPOSE: This study aimed to describe changes in femoral and lumbar bone mineral density (BMD) after 24 months of aromatase inhibitors (AIs) and antiresorptive treatment in postmenopausal women with estrogen receptor-positive breast cancer. METHODS: Prospective, longitudinal study in a real-life setting with a 2-year follow-up. Patients underwent a complete baseline bone assessment including clinical assessment, biological evaluation, BMD measurement, and spine X-ray. Antiresorptive treatment was prescribed to patients with a T-score < - 2 or a T-score < - 1.5 SD with additional osteoporosis risk factors. A follow-up bone assessment was carried out after 24 months. RESULTS: Among 328 patients referred to our center, 168 patients (67.7 ± 10.6 years) were included in our study, and 144 were eligible for antiresorptive treatment. After 24 months, patients receiving antiresorptive treatment experienced a significant increase of + 6.28% in femoral-BMD (F-BMD) and + 7.79% in lumbar-BMD (L-BMD). This increase was not significantly different between osteoporotic and osteopenic patients. Conversely, patients not receiving antiresorptive treatment presented significant F-BMD and L-BMD loss regardless of the baseline BMD. In the multivariate logistic model, the lack of antiresorptive treatment was the only predictive factor for major femoral bone loss with a 20.83 odds ratio (CI95%:4.2-100, p < 0.001). CONCLUSION: This real-life study confirmed that antiresorptive treatment significantly increases femoral and lumbar BMD regardless of the baseline BMD in postmenopausal patients receiving AIs for early breast cancer. Patients who did not receive antiresorptive treatment had a 20.8-fold increased risk of major bone loss. Nevertheless, the best threshold to adopt for starting antiresorptive agents remains undetermined.

Benefits of BNP/NT-proBNP serum level evaluation for dry weight adjustment in pediatric hemodialysis patients.

BACKGROUND: Dry weight (DW) adjustment in children on hemodialysis (HD) can be challenging. It relies on clinical evaluation and additional supports. Our aim was to study the benefits of cardiac biomarker assessment, in addition to the more commonly used technique, bioimpedance spectroscopy (BIS), and clinical signs for DW prescription in pediatric HD patients. METHOD: Observational study including 41 children on HD in three pediatric HD centers in the Paris region. During one session, BIS was performed before the session and serum levels of BNP and NT-proBNP were analyzed before and after the session. RESULTS: Median pre-dialysis level of BNP was 87 ng/L [24-192] and NT-proBNP 968 ng/L [442-4828]. Cardiac biomarker levels showed positive correlation with the BIS hydration status evaluation (p = 0.004). The most appropriate cutoff for pre-dialysis BNP to detect significant overhydration (OH) was 165 ng/L (sensitivity 0.67, specificity 0.84). Based on the BIS evaluation, only 32% of patients with high blood pressure (BP) had OH, whereas in the normal BP group, 33% had significant OH. CONCLUSIONS: DW prescription for children on HD should not only rely on clinical evaluation, particularly BP, but should also include additional helpful parameters. BIS is well-validated in children, but it has limitations in non-cooperative patients, and its cost can limit its use in some settings. Cardiac biomarkers, especially BNP, were well-correlated to hydration status evaluated by BIS, and thus could add valuable information for individual patient management and DW assessment.

Accès aux soins d'une population d'anciens travailleurs immigrés vivant en foyer.

The Chibanis represent the population of aging former immigrant workers who arrived in France in the 1970s in order to take up employment. Most of them still live in immigrant hostels, which are not appropriate for an older population. This anthropological study was conducted on Chibanis living in an immigrant hostel in the 15th arrondissement of Marseille. The objectives were to assess the medical, economic, and social characteristics of this population, to understand their access to health care, and to measure their adherence to the prevention actions of an association. 67 Chibanis aged 65 and over were included, with a median age of 77: 91% had access to a general practitioner, and 86.6% had more than two chronic diseases. More than half of the Chibanis complained of dental problems, and 20% complained of ophthalmological problems. Only 32.8% of the Chibanis included agreed to follow-up care with the nurses from the association. The population of Chibanis are isolated geographically from their families, live in poor socio-economic conditions, and often have insufficient medico-social coverage. They must "manage" their chronic diseases, as well as costly health problems such as dental or ophthalmic diseases. Improving care pathways for this population requires us to identify their specificities and all the factors hindering prevention actions.

Multiple Myeloma in Patients over 80: A Real World Retrospective Study of First Line Conservative Approach with Bortezomib Dexamethasone Doublet Therapy and Mini-Review of Literature.

Data on octogenarian patients with MM are scarce, and optimal management remains controversial. We report a retrospective cohort of unselected octogenarian patients with NDMM treated with bortezomib dexamethasone (Vd). Seventy-four patients were treated with an initial doublet therapy (Vd regimen, 2−3 cycles, induction). A dose escalation with an adjunction of melphalan or cyclophosphamide was proposed for patients who had an insufficient response after induction and who could tolerate it. In responders, the treatment was continued until progression or a plateau response for 6 months (consolidation). The overall response rate was 73%. After a median follow-up of 31.4 months, median progression-free survival (PFS) and overall survival (OS) were 13.2 and 26.9 months, respectively. PFS and OS of patients with ECOG PS < 3 (25.4 and 54.9 months, respectively) were better in comparison to PFS and OS of patients with ECOG PS ≥ 3 (9.3 and 11.3 months, respectively). Thirteen patients (17.6%) died during induction. Twelve patients (16.2%) died during consolidation. In conclusion, a conservative therapeutic strategy based on Vd resulted in a good response rate. However, the survival remains poor in the population of patients with an ECOG PS ≥ 3, mainly because of early mortality not related to progressive disease.

Geriatric syndromes in a centenarians population.

BACKGROUND: Centenarians develop diseases later than younger populations. AIMS: Assessment of geriatric syndromes in centenarians living in Marseille in 2020. METHODS: Observational preliminary study describing centenarians living in the Marseille area, being part of the patients base of the general practitioners (GPs). RESULTS: Twenty-two centenarians were enrolled, including seventeen women (77.3%). Thirteen centenarians lived in nursing homes (NH) and nine in private housing (PH). All were dependent for daily living activities and 78.9% used walkers to get around. GPs consultations were exclusively home visits (in NH or PH). Centenarians living in NH presented more cognitive impairments, more comorbidities, and fewer hospitalizations during the past year compared to centenarians living in PH. DISCUSSION: Although centenarians represent a model of successful aging for society, all were dependent and had at least one geriatric syndrome. CONCLUSIONS: Maintaining centenarians at home requires technical aids and intervention of several professional caregivers relying on family support.

Acceptance, efficacy, and safety of COVID-19 vaccination in older patients with cancer.

PURPOSE: The COVID-19 vaccination campaign began in December 2020, in France, and primarily targeted the oldest people. Our study aimed to determine the level of acceptance of vaccination in a population of older patients with cancer. METHODS: From January 2021, we offered vaccination with the BNT162b2 COVID-19 vaccine to all patients 70 years and older referred to our geriatric oncology center in Marseille University Hospital (AP-HM) for geriatric assessment before initiation of an oncological treatment. Objectives were to evaluate acceptance rate of COVID-19 vaccination and to assess vaccine safety, reactogenicity, and efficacy two months after the first dose. RESULTS: Between January 18, 2021 and May 7, 2021, 150 older patients with cancer were offered vaccination after a geriatric assessment. The majority were men (61.3%), with a mean age of 81 years. The two most frequent primary tumors were digestive (29.4%) and thoracic (18%). The vaccine acceptance rate was 82.6% and the complete vaccination rate (2 doses) reached 75.3%. Among the vaccinated patients, 15.9% reported mild side effects after the first dose and 23.4% after the second dose, mostly arm pain and fatigue. COVID-19 cases were observed in 5.1% of vaccinated patients compared with 16.7% in unvaccinated patients. Of the 22 vaccinated patients who agreed to have their serum tested, 15 had antibodies against the spike protein at day 21 after the first dose. CONCLUSION: Our study showed a high acceptance rate of COVID-19 vaccination, with good tolerance in this frail population. These results highlight the benefits of organizing vaccination campaigns at the very beginning of oncological management in older patients. CLINICAL TRIAL REGISTRATION: This study was registered May 23, 2019 in ClinicalTrials.gov (NCT03960593).

Prenatal bone abnormalities in three cases of familial hypocalciuric hypercalcemia.

INTRODUCTION: Prenatal diagnosis of bone and mineralization anomalies is associated with a wide range of etiologies and prognoses. The improvement of antenatal ultrasound combined with the development of molecular diagnosis in genetics has transformed antenatal medicine into a challenging discipline. Of the various known causes of bone abnormalities and hypomineralization, calcium and phosphate metabolism disorders are exceptional. An accurate diagnosis is crucial for providing appropriate genetic counseling and medical follow-up after birth. CASE: We report on three siblings with severe bone abnormalities diagnosed during the second trimester ultrasound of pregnancy. Postnatal follow-up showed transitory hyperparathyroidism, with hypercalcemia and hypocalciuria. METHODS: Sanger sequencing performed after birth in the three newborns revealed a monoallelic pathogenic variant in the CASR gene, encoding the calcium sensing receptor, confirming the diagnosis of familial hypocalciuric hypercalcemia, paternally inherited. Postnatal evolution was favorable after treatment with a calcimimetic agent. CONCLUSIONS: Previously, prenatal bone abnormalities caused by familial hypocalciuric hypercalcemia had only been described in one patient. This entity should be considered as differential diagnosis of bones abnormalities. Knowing about this unusual etiology is important to guide the diagnosis, the prenatal counseling and to improve medical management.

Targeted Therapy for Older Patients with Non-Small Cell Lung Cancer: Systematic Review and Guidelines from the French Society of Geriatric Oncology (SoFOG) and the French-Language Society of Pulmonology (SPLF)/French-Language Oncology Group (GOLF).

Systematic molecular profiling and targeted therapy (TKI) have changed the face of Non-Small Cell Lung Cancer (NSCLC) treatment. However, there are no specific recommendations to address the prescription of TKI for older patients. A multidisciplinary task force from the French Society of Geriatric Oncology (SoFOG) and the French Society of Pulmonology/Oncology Group (SPLF/GOLF) conducted a systematic review from May 2010 to May 2021. Protocol registered in Prospero under number CRD42021224103. Three key questions were selected for older patients with NSCLC: (1) to whom TKI can be proposed, (2) for whom monotherapy should be favored, and (3) to whom a combination of TKI can be proposed. Among the 534 references isolated, 52 were included for the guidelines. The expert panel analysis concluded: (1) osimertinib 80 mg/day is recommended as a first-line treatment for older patients with the EGFR mutation; (2) full-dose first generation TKI, such as erlotinib or gefitinib, is feasible; (3) ALK and ROS1 rearrangement studies including older patients were too scarce to conclude on any definitive recommendations; and (4) given the actual data, TKI should be prescribed as monotherapy. Malnutrition, functional decline, and the number of comorbidities should be assessed primarily before TKI initiation.

HoSAGE: sarcopenia in older patient with intermediate / high-risk prostate cancer, prevalence and incidence after androgen deprivation therapy: study protocol for a cohort trial.

BACKGROUND: Sarcopenia is defined by a loss of muscle strength associated to a decrease in skeletal muscle mass. Ageing greatly contributes to sarcopenia as may many other factors such as cancer or androgen deprivation therapies (ADT). This cohort study aims to evaluate (1) the prevalence of muscle disorders and sarcopenia in older patients before initiation of intermediate to high risk prostate cancer treatment with ADT and radiotherapy, and (2) the occurrence and/or aggravation of muscle disorders and sarcopenia at the end of cancer treatment. METHODS: This cohort study is monocentric and prospective. The primary objectives are to determine the risk factor of sarcopenia prevalence and to study the relationship between ADT and sarcopenia incidence, in patients 70 years and older with histologically proven localized or locally advanced prostate cancer, addressed to a geriatrician (G8 score ≤14) for comprehensive geriatric assessment (CGA) in Marseille University Hospital. Secondary objectives encompass, measurement of sarcopenia clinical criteria along prostate oncological treatment; evaluation of the quality of life of patients with sarcopenia; evaluation of the impact of socio-behavioral and anthropological factors on sarcopenia evolution and incidence; finally the evaluation of the impact of ADT exposure on sarcopenia. Sarcopenia prevalence was estimated to be between 20 and 30%, therefore the study will enroll 200 patients. DISCUSSION: The current guidelines for older patients with prostate cancer recommend a pelvic radiotherapy treatment associated to variable duration (6 to 36 months) of ADT. However ADT impacts muscle mass and could exacerbate the risks of sarcopenia. Our study intends to assess the specific effect of ADT on sarcopenia incidence and/or worsening as well as to estimate sarcopenia prevalence in this population. The results of this cohort trial will lead to a better understanding of sarcopenia prevalence and incidence necessary to further elaborate a prevention plan. TRIAL REGISTRATION: The protocol was registered to the French drug and device regulation agency under the number 2019-A02319-48, before beginning the study (11/12/2019). The ClinicalTrials.gov identifier is NCT04484246, registration on the ClinicalTrials.gov ( https://clinicaltrials.gov/ct2/show/NCT04484246 ).

Specific immune biomarker monitoring in two children with severe IgA nephropathy and successful therapy with immunoadsorption in a rapidly progressive case.

BACKGROUND: Childhood IgA nephropathy (cIgAN) is one of the most common primary glomerulonephritides with the potential to evolve to kidney failure. IgAN is an autoimmune disease involving 3 key factors: galactose-deficient IgA1 (Gd-IgA1), anti-IgA1 autoantibodies, and soluble (s)CD89 IgA Fc receptor. These molecules and immune complexes have been described recently as potential biomarkers of disease progression in childhood IgAN but their evolution in time under immunosuppressive treatment remains unknown. METHODS: We performed a prospective study of two proliferative cIgAN patients by sequentially biomonitoring immune IgA complexes (sCD89-IgA, IgG-IgA), sCD89, and Gd-IgA1 and correlating them with clinical and histological outcome after treatment. RESULTS: After patient 1's treatment, a decrease in sCD89-IgA, IgG-IgA, and free sCD89 was linked to a decrease in proteinuria whereas eGFR (estimated glomerular filtration rate) and Gd-IgA1 levels remained stable. Patient 1 received tacrolimus and monthly intramuscular steroid injections of Kenacort for 10 months. At the end, a relapse induced an increase in proteinuria consistent with an increase of the 3 biomarkers. Patient 2 displayed rapidly progressive IgAN with crescents in more than 90% of glomeruli and received intense immunosuppression treatment associated with the immunoadsorption (IA) approach. During IA, proteinuria decreased rapidly, as well as levels of CD89-IgA, IgG-IgA, sCD89, and Gd-IgA1 biomarkers. After discontinuation of IA, proteinuria increased as well as IgG-IgA complexes whereas sCD89-IgA and sCD89 remained low. Further re-intensification of IA and addition of cyclophosphamide improved proteinuria again with reduced IgG-IgA. A second biopsy was performed showing a reduction of extracapillary proliferation to 6% of glomeruli and only 9% glomerulsoclerosis. CONCLUSIONS: In conclusion, sequential biomonitoring of Gd-IgA1, IgA-immune complexes, and sCD89 in cIgAN was found to be valuable, by correlating with clinical features and glomerular proliferative lesions in cIgAN. These biomarkers could represent useful tools to evaluate kidney injury without repeat kidney biopsies.

Functional status in older patients with lung cancer: an observational cohort study.

PURPOSE: An assessment of the impact of functional status (FS) evaluated using a combination of Activities of Daily Living (ADL) and the short version of the Instrumental Activities of Daily Living (IADL), on 3- and 6- month mortality and on 3-month unplanned hospitalizations in older patients treated for lung cancers. METHOD AND OBJECTIVES: This observational retrospective study was conducted between September 2015 and January 2019 at Marseille University Hospital (AP-HM). During this period, all consecutive outpatients aged 70 years or older referred for a comprehensive geriatric assessment (CGA) before the initiation of lung cancer treatment were enrolled. RESULTS: Two hundred twenty-seven patients were analyzed: the median age was 78.7 years and 74.0% were male. Almost half of the patients were metastatic (45.4%). Concerning FS, 41.9% of patients had no ADL-IADL impairment, 30.0% had either IADL or ADL impairment, and both ADL-IADL were impaired for 28.1%. Impaired ADL-IADL was associated with poor nutritional status, depression, mobility, and cognitive disorders. In a logistic regression model, ADL or IADL impairment (aOR = 2.1; 95% CI [1.0-4.2]; p = 0.037) and impaired ADL-IADL (aOR = 2.6; 95% CI [1.2-5.3]; p = 0.012) were independently associated with a higher risk of unplanned hospitalizations within 3 months. In the multivariate Cox model, 6-month mortality risk was independently associated with impaired ADL-IADL (aHR = 2.3; 95% CI [1.3-4.4]; p = 0.008). CONCLUSION: The combination of ADL and IADL scales to assess FS is a prognostic marker of the mortality risk at 6 months in older patients with lung cancer and should be more largely used by oncologists in treatment decision making.
