Relevance of blood tumor markers in inpatients with significant involuntary weight loss and elevated levels of inflammation biomarkers.

PURPOSE: To assess the diagnostic performance of a panel of standard tumor markers (TMs) in patients hospitalized with significant involuntary weight loss (IWL) and elevated levels of inflammation biomarkers, and a combination of the TM panel and the finding of the computed tomography (CT) scan. METHODS: We conducted a retrospective study in the internal medicine department at Amiens-Picardie University Medical Center (Amiens, France) between January 1st, 2015, and November 1st, 2021. The inclusion criteria were age 18 or over, significant IWL (≥ 5 kg over 6 months), elevated inflammation biomarkers (e.g. C-reactive protein), and assay data on two or more standard TMs (carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19 - 9, CA 15 - 3, CA 125, neuron-specific enolase (NSE), alpha-fetoprotein (AFP), calcitonin, and prostate-specific antigen (PSA)). The result of each TM assay was interpreted qualitatively (as positive or negative), according to our central laboratory's usual thresholds. RESULTS: Cancer was diagnosed in 50 (37.0%) of the 135 patients included. Positivity for one or more TMs had a positive predictive value (PPV) of 0.55 [0.43-0.66], and a negative predictive value (NPV) of 0.84 [0.75-0.93] for cancer diagnosis. When combined with the presence of suspicious CT findings (e.g. a mass, enlarged lymph nodes and/or effusion), positivity for one or more TMs had a PPV of 0.92 [0.08-0.30]. In the absence of suspicious CT findings, a fully negative TM panel had an NPV of 0.96 [0.89-1.00]. CONCLUSION: A negative TM panel argues against the presence of a cancer, especially in the absence of suspicious CT findings.

Clinical presentation, course, and prognosis of patients with mixed connective tissue disease: A multicenter retrospective cohort.

OBJECTIVES: The objective of this study is to better characterize the features and outcomes of a large population of patients with mixed connective tissue disease (MCTD). METHODS: We performed an observational retrospective multicenter cohort study in France. Patients who fulfilled at least one diagnostic criterion set for MCTD and none of the criteria for other differentiated CTD (dCTD) were included. RESULTS: Three hundred and thirty patients (88% females, median [interquartile range] age of 35 years [26-45]) were included. The diagnostic criteria of Sharp or Kasukawa were met by 97.3% and 93.3% of patients, respectively. None met other classification criteria without fulfilling Sharp or Kasukawa criteria. After a median follow-up of 8 (3-14) years, 149 (45.2%) patients achieved remission, 92 (27.9%) had interstitial lung disease, 25 (7.6%) had pulmonary hypertension, and 18 (5.6%) died. Eighty-five (25.8%) patients progressed to a dCTD, mainly systemic lupus erythematosus (15.8%) or systemic sclerosis (10.6%). Median duration between diagnosis and progression to a dCTD was 5 (2-11) years. The presence at MCTD diagnosis of an abnormal pattern on nailfold capillaroscopy (odds ratio [OR] = 2.44, 95% confidence interval [95%CI] [1.11-5.58]) and parotid swelling (OR = 3.86, 95%CI [1.31-11.4]) were statistically associated with progression to a dCTD. Patients who did not progress to a dCTD were more likely to achieve remission at the last follow-up (51.8% vs. 25.9%). CONCLUSIONS: This study shows that MCTD is a distinct entity that can be classified using either Kasukawa or Sharp criteria, and that only 25.8% of patients progress to a dCTD during follow-up.

Promoting crucial team building, collaboration, and communication skills in graduate students through interactive retreats.

Biomedical graduate students receive intensive training in their scientific area of interest yet need additional skills for successful scientific careers. Our aim was to promote team building, improve collaborations and enhance communication skills. An off-site yearly retreat was organized for the graduate students in our NIH-funded Research Initiative for Scientific Enhancement (RISE) graduate training program. Retreat themes were addressed through short presentations, case studies, live podcasts, webinars, focus groups, role-play, and breakout sessions with various team building exercises to practice communication skills and identify abilities, knowledge, values, and behaviors. Trainees gave short presentations and served as discussion leaders on topics related to the central theme. Expert guest speakers participated in discussion sessions with the trainees. Trainees evaluated the retreats at the end. A total of 48 trainees, 12 RISE Program faculty and staff, and 26 external speakers from industry, academia, media/journalism, the arts, psychology, and holistic medical fields participated over 9 years. The overall average benefit of the in-person retreats was rated 4.80 on a Likert scale of 1-5 by trainees. Trainees particularly enjoyed the informal interactions with program faculty, staff, and fellow trainees. They appreciated the opportunity to learn soft skills, such as interpersonal communication, conflict resolution, and leadership. Two additional retreats conducted virtually because of the COVID-19 pandemic were perceived as less beneficial. We conclude that off-site interactive retreats are a valuable tool for enhancing soft skills and a sense of team identity in a biomedical sciences graduate program, while covering important issues related to scientific careers.NEW & NOTEWORTHY Off-site interactive science-related retreats are a valuable tool for enhancing soft skills and sense of team identity in a biomedical sciences graduate program, while covering important issues related to pursuing a career in science. There are many perceived benefits, so we encourage other training programs to include a similar type of regular activity in students' training with the goal of improving trainee well-being and supporting their academic and research productivity.

Value of Positron Emission Tomography Coupled With Computed Tomography for the Diagnosis of Inflammatory Syndrome of Unknown Origin in an Internal Medicine Department.

Objective: To evaluate the usefulness of positron emission tomography (PET) coupled with computed tomography (CT) in the diagnostic workup for inflammatory syndrome of undetermined origin (IUO) and to determine the diagnostic delay in an internal medicine department. Patients and methods: We retrospectively studied a cohort of patients for whom a PET/CT scan had been prescribed in an indication of IUO in an internal medicine department (Amiens University Medical Center, Amiens, France) between October 2004 and April 2017. The patients were grouped according to the PET/CT findings: very useful (enabling an immediate diagnosis), useful, not useful, and misleading. Results: We analyzed 144 patients. The median (interquartile range) age was 67.7 years (55.8-75.8 years). The final diagnosis was an infectious disease in 19 patients (13.2%), cancer in 23 (16%), inflammatory disease in 48 (33%), and miscellaneous diseases in 12 (8.3%). No diagnosis was made in 29.2% of the cases; half of the remaining had a spontaneously favorable outcome. Fever was observed in 63 patients (43%). Positron emission tomography coupled with CT was determined to be very useful in 19 patients (13.2%), useful in 37 (25.7%), not useful in 63 (43.7%), and misleading in 25 (17.4%). The median diagnostic delay (ie, the time interval between the first admission and a confirmed diagnosis) was significantly shorter in the useful (71 days [38-170 days]) and very useful (55 days [13-79 days]) groups than that in the not useful group (175 days [51-390 days]; P<.001). The median time interval between the PET/CT scan and the diagnosis was twice as long in the not useful group than that in the pooled misleading, useful, or very useful groups (P=.03). In a univariate analysis, the poor overall condition (P=.007) and the absence of fever (P=.005) were predictive of usefulness of PET/CT. Conclusion: Positron emission tomography coupled with CT seems to be useful in the diagnosis of IUO and might shorten the diagnostic delay.

Deep Learning on Bone Scintigraphy to Detect Abnormal Cardiac Uptake at Risk of Cardiac Amyloidosis.

BACKGROUND: Cardiac uptake on technetium-99m whole-body scintigraphy (WBS) is almost pathognomonic of transthyretin cardiac amyloidosis. The rare false positives are often related to light-chain cardiac amyloidosis. However, this scintigraphic feature remains largely unknown, leading to misdiagnosis despite characteristic images. A retrospective review of all WBSs in a hospital database to detect those with cardiac uptake may allow the identification of undiagnosed patients. OBJECTIVES: The authors sought to develop and validate a deep learning-based model that automatically detects significant cardiac uptake (Perugini grade ≥2) on WBS from large hospital databases in order to retrieve patients at risk of cardiac amyloidosis. METHODS: The model is based on a convolutional neural network with image-level labels. The performance evaluation was performed with C-statistics using a 5-fold cross-validation scheme stratified so that the proportion of positive and negative WBSs remained constant across folds and using an external validation data set. RESULTS: The training data set consisted of 3,048 images: 281 positives (Perugini grade ≥2) and 2,767 negatives. The external validation data set consisted of 1,633 images: 102 positives and 1,531 negatives. The performance of the 5-fold cross-validation and external validation was as follows: 98.9% (± 1.0) and 96.1% for sensitivity, 99.5% (± 0.4) and 99.5% for specificity, and 0.999 (SD = 0.000) and 0.999 for the area under the curve of the receiver-operating characteristic curves. Sex, age <90 years, body mass index, injection-acquisition delay, radionuclides, and the indication of WBS only slightly affected performances. CONCLUSIONS: The authors' detection model is effective at identifying patients with cardiac uptake Perugini grade ≥2 on WBS and may help in the diagnosis of patients with cardiac amyloidosis.

Anti-SAE autoantibody in dermatomyositis: original comparative study and review of the literature.

OBJECTIVE: Among specific autoantibodies in DM, the anti-small ubiquitin-like modifier activating enzyme (SAE) antibody is rare. We aim to describe the clinical characteristics, cancer prevalence, and muscle pathology of anti-SAE-positive DM. METHODS: Patients with a diagnosis of DM and sera positive for the anti-SAE antibody were recruited from 19 centres in this retrospective observational study. The available muscular biopsies were reviewed. We conducted a comparison with anti-SAE-negative DM and a review of the literature. RESULTS: Of the patients in the study (n = 49), 84% were women. Skin involvement was typical in 96% of patients, with 10% having calcinosis, 18% ulceration and 12% necrosis; 35% presented with a widespread skin rash. Muscular disease affected 84% of patients, with mild weakness [Medical Research Council (MRC) scale 4 (3, 5)], although 39% of patients had dysphagia. Muscular biopsies showed typical DM lesions. Interstitial lung disease was found in 21% of patients, mainly with organizing pneumonia pattern, and 26% of patients showed dyspnoea. Cancer-associated myositis was diagnosed in 16% of patients and was responsible for the majority of deaths, its prevalence being five times that of the general population. IVIG therapy was administered to 51% of the patients during the course of the disease. Comparison with anti-SAE-negative DM (n = 85) showed less and milder muscle weakness (P = 0.02 and P = 0.006, respectively), lower creatinine kinase levels (P < 0.0001) and less dyspnoea (P = 0.003). CONCLUSION: Anti-SAE positive DM is a rare subgroup associated with typical skin features but a potentially diffuse rash, a mild myopathy. Interstitial lung disease defines an organizing pneumonia pattern. Cancer associated DM prevalence is five times that of the general population.

Cutaneous involvement in relapsed multiple myeloma.

Cutaneous involvement in multiple myeloma with extramedullary disease is rare. We report the case of a refractory multiple myeloma patient who developed a cutaneous lesion. Histopathology revealed dermal immature plasma cell infiltrate with a lack of CD138 expression. This cutaneous location was associated with an aggressive clinical course and short survival.

Outcome of COVID-19 in patients with rheumatic and inflammatory diseases treated with mycophenolic acid: data from the French RMD COVID-19 cohort.

BACKGROUND: Patients with inflammatory rheumatic and musculoskeletal diseases (iRMD) receiving mycophenolic acid (MPA) may have a less favourable outcome from COVID-19 infection. Our aim was to investigate whether MPA treatment is associated with severe infection and/or death. METHODS: IRMD patients with and without MPA treatment with highly suspected/confirmed COVID-19 were included in this observational multicentre study. The primary outcome was death rate from COVID-19 with secondary objectives to determine the severity of infection and length of hospital stay. Outcome comparisons were made using regression models with and without adjustment on prespecified confounding factors. ORs, sub-HR (sHR) and 95% CIs were calculated using patients not treated with MPA as a reference group. RESULTS: Of the 1977 patients, 1928 were not treated with MPA (393 were MPA eligible), and 49 patients were treated with MPA. MPA-treated patients had more severe disease, longer hospital stays and higher death rate from COVID-19 than non-MPA patients (OR 8.02 (95% CI 3.35 to 19.20), p<0.001; sHR 0.57 (95% CI 0.33 to 0.98), p=0.040; OR 11.58 (95% CI 4.10 to 32.69), p<0.001). In adjusted analyses, however, no outcome was independently associated with MPA treatment. Death rate, severity and length of hospital stay of MPA-treated patients were not significantly different from those of not treated but MPA-eligible patients. CONCLUSION: MPA therapy is not associated with a more severe COVID-19 infection. However, due to increased vulnerability of developing a severe form of COVID-19, careful consideration should be taken with iRMD patients likely to be treated with MPA. TRIAL REGISTRATION NUMBER: NCT04353609.

Comparison between idiopathic and VEXAS-relapsing polychondritis: analysis of a French case series of 95 patients.

OBJECTIVE: A new adult-onset autoinflammatory syndrome has been described, named VEXAS (Vacuoles, E1 Enzyme, X-linked, Autoinflammatory, Somatic). We aimed to compare the clinical characteristics, the laboratory features and the outcomes between idiopathic-relapsing polychondritis (I-RP) and VEXAS-relapsing polychondritis (VEXAS-RP). METHODS: Patients from French retrospective multicentre cohort of RP were separated into two groups: a VEXAS-RP and an I-RP. RESULTS: Compared with patients with I-RP (n=40), patients with VEXAS-RP (n=55) were men (96% vs 30%, p<0.001) and were older at diagnosis (66 vs 44 years, p<0.001). They had a greater prevalence of fever (60% vs 10%, p<0.001), of skin lesions (82% vs 20%, p<0.001), of ocular involvement (57% vs 28%, p=0.01), of pulmonary infiltrates (46% vs 0%, p<0.001), of heart involvement (11% vs 0%, p=0.0336) and with higher median C-reactive protein levels (64 mg/L vs 10 mg/L, p<0.001). Seventy-five per cent of the patients with VEXAS-RP had myelodysplastic syndrome (MDS) versus none in I-RP group. The glucocorticoids use, and the number of steroid sparing agents were similar in both groups, but patients with VEXAS-RP had more frequent refractory disease (remission obtained in 27% vs 90%, p<0001). VEXAS-RP was associated with higher risk of death: six patients (11%) died in the VEXAS-RP group after a median follow-up of 37 months and none in the I-RP group after a median follow-up of 92 months (p<0.05). CONCLUSION: We report the largest cohort of VEXAS-RP, characterised by high prevalence of male sex, fever, skin lesion, ocular involvement, pulmonary infiltration, heart involvement, older age and MDS association.

Venous thromboembolism during systemic inflammatory and autoimmune diseases associated with myelodysplastic syndromes, chronic myelomonocytic leukaemia and myelodysplastic/myeloproliferative neoplasms: a French multicentre retrospective case-control study.

OBJECTIVES: Myelodysplastic syndromes (MDS) and chronic myelomonocytic leukaemia (CMML) are associated with systemic inflammatory and autoimmune diseases (SIADs) in 10-30% of cases. The aims of this study were (i) to evaluate the prevalence of venous thromboembolism VTE in patients presenting with both MDS/CMML and SIADs, (ii) to describe risk factors associated with thrombosis, and (iii) to analyse the impact of VTE on overall survival and transformation to acute myeloid leukaemia in comparison to patients with MDS/CMML-associated SIADs without VTE. METHODS: This retrospective multicentre case-control study was conducted among patients with MDS/CMML and dysimmune disorders and featured in the French retrospective database of the French Network of Dysimmune Disorders Associated with Hemopathies (MINHEMON), diagnosed with MDS/CMML and dysimmune disorders. RESULTS: During a median follow-up of 16 months (5-48) VTE occurred in 35 patients (21.6 %) whereas 127 patients did not. Among those with VTE, 8 patients (22.9%) experienced two or more VTE. Common prothrombotic risk factors were not significantly different in patients with or without VTE. CMML was more frequent in patients without VTE (37 % vs. 14.3%, p=0.01), whereas myelodysplasic/myeloproliferative neoplasm (MDS/MPN) was higher in VTE patients (20 % vs. 5.5 %, p=0.01). In a multivariate analysis, only MDS/CMML progression at the time of VTE (odds ratio 28.82, 95 % CI (5.52-530.70) was significantly associated with VTE. When treated with an anticoagulation therapy, bleeding occurred in 19.4% of cases (6/31). Overall survival was not significantly different between patients with and without VTE (p=0.68). Leukaemia-free survival between groups was not significantly different (p=0.83). CONCLUSIONS: VTE is a common complication in MDS/CMML-associated SIADSs with an increased risk of bleeding when treated by anticoagulants. In the MDS/CMML subgroup, SIADS flares and MDS/CMML progression seem to be prothrombotic risk factors.

Prognostic factors of Pasteurella infections: a single-center retrospective cohort study over a 14-year period (2005-2018).

BACKGROUND: Pasteurella spp. can lead to fatal infections in humans. OBJECTIVE: To assess prognostic factors of invasive pasteurellosis. METHODS: We conducted a single retrospective cohort study of local versus invasive Pasteurella infections from January 1, 2005, to December 31, 2018, in the Amiens-Picardie University Hospital, France. RESULTS: Forty-five (20.9%) invasive pasteurellosis and 22 (10.2%) complicated local infections were reported among a total of 215 Pasteurella infections. The mortality rate among invasive infections was 22.2% (10/ 45) whereas no death was recorded in local infections group. Non-drug-induced prothrombin time test <70% of standard and platelet counts <100,000/mm3 were more frequent in non-survivors than in survivors (p=0.005 and p=0.019) in univariate analyses. A history of neoplasia (adjusted OR=13.62, p=0.020), an evidence of bacteremia (adjusted OR=20.68, p=0.025), and hemoglobin level <10 g/dL (adjusted OR=17.80, p=0.028) were identified as poor prognostic factors in multivariate analyses. CONCLUSION: Invasive pasteurellosis appears as a serious disease in vulnerable patients, particularly if bacteremia and/or coagulopathies occur.

COVID-19 in DMARD-treated patients with inflammatory rheumatic diseases: Insights from an analysis of the World Health Organization pharmacovigilance database.

BACKGROUND: To determine whether the use of disease-modifying antirheumatic drugs (DMARDs) is linked to the risk of COVID-19 among patients with inflammatory rheumatic diseases (IRDs). METHODS: We performed a disproportionality analysis of the World Health Organization pharmacovigilance database between January 1, 2020, and June 10, 2020. The frequency of COVID-19 reports for all DMARD classes identified was compared with that for all other reports for all other drugs and quoted as the reporting odds ratio (ROR) (95% confidence interval [CI]). RESULTS: Among 980,446 individual case-safety reports voluntarily recorded in the database, 398 identified COVID-19 in DMARD-treated patients with IRDs. There were 177 (44.5%) patients with rheumatoid arthritis (RA), 120 (30.1%) with ankylosing spondylitis (AS), 93 (23.4%) with psoriatic arthritis (PsA), and 8 (2.0%) with juvenile idiopathic arthritis. Most of the cases of COVID-19 occurred in patients taking anti-TNF agents (84.2%), resulting in a significant disproportionality signal (ROR [95% CI]: 8.31 [7.48-9.23]) - particularly in patients with RA, AS or PsA. A significant inverse disproportionality was found for the anti-IL-6 agent tocilizumab (ROR [95% CI]: 0.12 [0.02-0.88]) and JAK inhibitors (ROR [95% CI]: 0.33 [0.19-0.58]) in patients with RA - suggesting that these two drug classes are safer in the context of RA. CONCLUSION: Our results are in line with the literature on a potentially better safety profile for anti-IL-6 agents and JAK inhibitors. The WHO pharmacovigilance data suggest that COVID-19 is significantly more frequent in patients with IRDs treated with TNF inhibitors.

Analysis of Mesencephalic Astrocyte-derived Neurotrophic Factor in Multiple Myeloma.

BACKGROUND/AIM: Multiple myeloma (MM) is characterized by high production of immunoglobulins resulting in a constant source of endoplasmic reticulum (ER)-stress. Mesencephalic astrocyte-derived neurotrophic factor (MANF) was identified as a possible circulating biomarker that could help in monitoring ER-stress mediated diseases. MATERIALS AND METHODS: To assess the relevance of MANF in MM, we performed in silico and in vitro analysis in malignant cell lines including the myeloma cell line RPMI 8226. Serum MANF concentration was compared between healthy subjects (n=60), patients with MM (n=68), or those with monoclonal gammopathy of undetermined significance (MGUS) (n=73). RESULTS: MANF mRNA expression was upregulated in the RPMI 8226 cell line, and higher secretion of MANF was measured in RPMI 8226 supernatant. Serum MANF levels were not significantly different between MM or MGUS patients and those in age- and sex-matched healthy controls. CONCLUSION: MANF was not validated as a biomarker of interest in MM patients. Its potential implication in myeloma pathogenesis should be investigated.

Cardiac involvement in adult-onset Still's disease: Manifestations, treatments and outcomes in a retrospective study of 28 patients.

OBJECTIVE: Adult-onset Still's disease (AOSD) is a rare inflammatory disease that may be life-threatening if complicated by cardiac problems. We performed a retrospective multicenter study to describe the manifestations, treatments and outcomes of cardiac involvement in AOSD. METHODS: We reviewed the medical databases of eight centers. All AOSD patients identified as fulfilling Yamagushi's or Fautrel's criteria were included in the study. Cardiac involvement, clinical manifestations, laboratory features, the course of the disease and treatments were evaluated. RESULTS: We included 96 AOSD patients in this study: 28 (29%) had documented cardiac involvement (AOSD + C group) and 68 (71%) had no cardiac involvement (control group). Cardiac complications were observed at diagnosis in 89% of cases. It were pericarditis (n = 17), tamponade (n = 5), myocarditis (n = 5) and non-infectious endocarditis (n = 1). Levels of leukocytes, neutrophils and C-reactive protein were significantly higher (p = 0.02, p = 0.02 and p = 0.002, respectively in the AOSD + C group than in the control group. Admission to intensive care, and the use of biotherapy were more frequent during follow-up in the AOSD + C group than the control group (p = 0.0001 and p = 0.03 respectively). Cardiac involvement was associated with refractory form in multivariate analyzed (p = 0.01). Corticosteroids were effective with or without methotrexate in 71% of patients but not in severe involvement as myocarditis or tamponade. CONCLUSION: Cardiac complications are frequent, inaugural, can be life-threatening and predictive of a refractory course in patients with AOSD. Systematic cardiac screening should be proposed at diagnosis and biotherapy early use should be considered especially in myocarditis.

Acute Airway Obstruction and Cardiopulmonary Arrest due to Tracheomalacia Caused by Megaesophagus Compression Secondary to Achalasia.

We report the case of an 80-year-old woman who presented one episode of cardiopulmonary arrest and two episodes of acute airway obstruction. We found in this patient the presence of tracheomalacia caused by megaesophagus compression secondary to achalasia probably responsible for episodes of acute airway obstruction and cardiopulmonary arrest.

Case Studies and Literature Review of Pneumococcal Septic Arthritis in Adults.

We conducted a retrospective study on all cases of pneumococcal septic arthritis (SA) in patients >18 years of age reported to the Picardie Regional Pneumococcal Network in France during 2005-2016. Among 1,062 cases of invasive pneumococcal disease, we observed 16 (1.5%) SA cases. Although SA is uncommon in adult patients, the prevalence of pneumococcal SA in the Picardie region increased from 0.69% during 2005-2010 to 2.47% during 2011-2016 after introduction of the pneumococcal 13-valent conjugate vaccine. We highlight the emergence of SA cases caused by the 23B serotype, which is not covered in the vaccine.
