Coexisting sarcoidosis and systemic lupus erythematosus: a case report and literature review

The coexistence of sarcoidosis and SLE in the same patient has uncommonly been reported. Information on the epidemiology, clinical presentation, and management of this rare association is scarce. We report a 46-year-old Hispanic man who was recently diagnosed with concomitant SLE and sarcoidosis at our institution. A diagnosis of sarcoidosis was established due to the presence of dyspnea, fever, and malaise along with bilateral hilar lymphadenopathy and histological evidence of non-caseating granuloma. In addition, he fulfilled the American Rheumatism Association (ACR) criteria for SLE due to a history of photosensitivity, polyarthritis, lymphocytopenia, and positivity of ANA and anti-dsDNA antibodies. He was successfully treated with a combination of oral glucocorticoids, hydroxychloroquine, and methotrexate. In a further step, we conducted an extensive literature review to further investigate into the association of sarcoidosis and SLE. We identified 25 additional published cases. The concurrence of these two conditions may be more common than previously reported, mainly affecting young female adults in the fourth decade of life. The most common manifestation of sarcoidosis was mild pulmonary symptoms whereas SLE presentation was highly variable. Most patients were positive for anti-dsDNA antibodies. Different therapeutic strategies included oral glucocorticoids, hydroxychloroquine, conventional immunosuppressive drugs and, cyclophosphamide in severe cases. Our study reinforces the need of considering the potential concurrence of sarcoidosis and SLE. Clinicians should be aware of the potential presence of SLE in patients with a diagnosis of sarcoidosis presenting with cutaneous manifestations, cytopenia, renal involvement, and/or positivity for ANA and anti-dsDNA antibodies

Association of kinesiophobia with catastrophism and sensitization-associated symptoms in COVID-19 survivors with post-COVID pain

Pain symptoms after the acute phase of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are present in almost 50% of COVID-19 survivors. The presence of kinesiophobia is a risk factor which may promote and perpetuate pain. This study aimed to investigate variables associated with the presence of kinesiophobia in a sample of previously hospitalized COVID-19 survivors exhibiting post-COVID pain. An observational study was conducted in three urban hospitals in Spain, including one hundred and forty-six COVID-19 survivors with post-COVID pain. Demographic (age, weight, height), clinical (intensity and duration of pain), psychological (anxiety level, depressive level, sleep quality), cognitive (catastrophizing), sensitization-associated symptoms, and health-related quality of life variables were collected in 146 survivors with post-COVID pain, as well as whether they exhibited kinesiophobia. Stepwise multiple linear regression models were conducted to identify variables significantly associated with kinesiophobia. Patients were assessed a mean of 18.8 (SD 1.8) months after hospital discharge. Kinesiophobia levels were positively associated with anxiety levels (r: 0.356, p < 0.001), depression levels (r: 0.306, p < 0.001), sleep quality (r: 0.288, p < 0.001), catastrophism (r: 0.578, p < 0.001), and sensitization-associated symptoms (r: 0.450, p < 0.001). The stepwise regression analysis revealed that 38.1% of kinesiophobia variance was explained by catastrophism (r² adj: 0.329, B = 0.416, t = 8.377, p < 0.001) and sensitization-associated symptoms (r² adj: 0.381, B = 0.130, t = 3.585, p < 0.001). Kinesiophobia levels were associated with catastrophism and sensitization-associated symptoms in previously hospitalized COVID-19 survivors with post-COVID pain. Identification of patients at a higher risk of developing a higher level of kinesiophobia, associated with post-COVID pain symptoms, could lead to better therapeutic strategies.Funding: The project was supported by a grant of Comunidad de Madrid y la Unión Europea, a través del Fondo Europeo de Desarrollo Regional (FEDER), Recursos REACT-UE del Programa Operativo de Madrid 2014–2020, financiado como parte de la respuesta de la Unión a la pandemia de COVID-19 (LONG-COVID-EXP-CM), by a grant from Next-Val 2021 de la Fundación Instituto de Investigación Marqués de Valdecilla (IDIVAL), and by a grant from the Novo Nordisk Foundation 0067235.

Prevalence of Neuropathic Component in Post-COVID Pain Symptoms in Previously Hospitalized COVID-19 Survivors

Objectives. To investigate the prevalence of neuropathic pain symptoms and to analyze the correlation between neuropathic symptoms with pain-related, psychological, and cognitive variables in COVID-19 survivors exhibiting ?de novo? post-COVID pain. Methods. Seventy-seven (n?=?77) previously hospitalized COVID-19 survivors presenting with post-COVID pain completed demographic (such as age, height, and weight), pain-related (the duration and intensity of pain), psychological (depressive/anxiety levels), and cognitive (catastrophizing and kinesiophobia) variables. The Self-Report Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) questionnaire was also assessed. After conducting multivariable correlation analyses, a stepwise multiple linear regression model was performed to identify S-LANSS predictors. Results. Participants were assessed a mean of 6.0 (SD 0.8) months after hospital discharge. Nineteen (24.6%) exhibited neuropathic pain symptoms (S-LANSS score?12 points). The S-LANSS score was positively associated with the duration of post-COVID pain (r: 0.262), anxiety levels (r: 0.275), and kinesiophobia level (r: 0.291) (all, ?<?0.05). The stepwise regression analysis revealed that 12.8% of the S-LANSS variance was just explained by kinesiophobia. Conclusion. This study found that almost 25% of previously hospitalized COVID-19 survivors with ?de novo? post-COVID pain reported a neuropathic pain component. The presence of neuropathic pain symptomatology was associated with more anxiety and kinesiophobia, but only kinesiophobia level was significantly associated explaining 12.8% of the variance of the S-LANSS score.Acknowledgments: This work was supported by Fundación Instituto de Investigación Marqués de Valdecilla (IDIVAL) (NVAL21/26)

Data-Driven Path Analytic Modeling to Understand Underlying Mechanisms in COVID-19 Survivors Suffering from Long-Term Post-COVID Pain: A Spanish Cohort Study

Pain can be present in up to 50% of people with post-COVID-19 condition. Understanding the complexity of post-COVID pain can help with better phenotyping of this post-COVID symptom. The aim of this study is to describe the complex associations between sensory-related, psychological, and cognitive variables in previously hospitalized COVID-19 survivors with post-COVID pain, recruited from three hospitals in Madrid (Spain) by using data-driven path analytic modeling. Demographic (i.e., age, height, and weight), sensory-related (intensity or duration of pain, central sensitization-associated symptoms, and neuropathic pain features), psychological (anxiety and depressive levels, and sleep quality), and cognitive (catastrophizing and kinesiophobia) variables were collected in a sample of 149 subjects with post-COVID pain. A Bayesian network was used for structural learning, and the structural model was fitted using structural equation modeling (SEM). The SEM model fit was excellent: RMSEA &lt; 0.001, CFI = 1.000, SRMR = 0.063, and NNFI = 1.008. The only significant predictor of post-COVID pain was the level of depressive symptoms (?=0.241, p = 0.001). Higher levels of anxiety were associated with greater central sensitization-associated symptoms by a magnitude of ?=0.406 (p = 0.008). Males reported less severe neuropathic pain symptoms (-1.50 SD S-LANSS score, p &lt; 0.001) than females. A higher level of depressive symptoms was associated with worse sleep quality (?=0.406, p &lt; 0.001), and greater levels of catastrophizing (?=0.345, p &lt; 0.001). This study presents a model for post-COVID pain where psychological factors were related to central sensitization-associated symptoms and sleep quality. Further, maladaptive cognitions, such as catastrophizing, were also associated with depression. Finally, females reported more neuropathic pain features than males. Our data-driven model could be leveraged in clinical trials investigating treatment approaches in COVID-19 survivors with post-COVID pain and can represent a first step for the development of a theoretical/conceptual framework for post-COVID pain.Funding: The project was supported by a grant of Comunidad de Madrid y la Unión Europea, a través del Fondo Europeo de Desarrollo Regional (FEDER), Recursos REACT-UE del Programa Operativo de Madrid 2014–2020, financiado como parte de la respuesta de la Unión a la pandemia de COVID-19 (LONG-COVID-EXP-CM), and by a grant from Next-Val 2021 de la Fundación Instituto de Investigación Marqués de Valdecilla (IDIVAL).

Alterations in circulating mitochondrial signals at hospital admission for COPD exacerbation

Background: Chronic obstructive pulmonary disease (COPD) exacerbation (ECOPD) alters the natural course of the disease. To date, only C-reactive protein has been used as a biomarker in ECOPD, but it has important limitations. The mitochondria release peptides (Humanin (HN), FGF-21, GDF-15, MOTS-c and Romo1) under certain metabolic conditions. Here, we aimed to evaluate the pathophysiologic, diagnostic and prognostic value of measuring serum mitochondrial peptides at hospital admission in patients with ECOPD. Methods: A total of 51 consecutive patients admitted to our hospital for ECOPD were included and followed for 1 year; in addition, 160 participants with stable COPD from our out-patient clinic were recruited as controls. Results: Serum FGF-21 (p < .001), MOTS-c (p < .001) and Romo1 (p = .002) levels were lower, and GDF-15 (p < .001) levels were higher, in patients with ECOPD than stable COPD, but no differences were found in HN. In receiver operating characteristic analysis, MOTS-c (AUC 0.744, 95% CI 0.679-0.802, p < .001) and GDF-15 (AUC 0.735, 95% CI 0.670-0.793, p < .001) had the best diagnostic power for ECOPD, with a diagnostic accuracy similar to that of C-RP (AUC 0.796 95% IC 0.735-0.848, p < .001). FGF-21 (AUC 0.700, 95% CI 0.633-0.761, p < .001) and Romo1 (AUC 0.645 95% CI 0.573-0.712, p = .001) had lower diagnostic accuracy. HN levels did not differentiate patients with ECOPD versus stable COPD (p = .557). In Cox regression analysis, HN (HR 2.661, CI95% 1.009-7.016, p = .048) and MOTS-c (HR 3.441, CI95% 1.252-9.297, p = .016) levels exceeding mean levels were independent risk factors for re-admission. Conclusions: Most mitochondrial peptides are altered in ECOPD, as compared with stable COPD. MOTS-c and GDF15 levels have a diagnostic accuracy similar to C-RP for ECOPD. HN and MOTS-c independently predict future re-hospitalization.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported by the Instituto de investigación sanitaria of Cantabria (IDIVAL): NextVAL grant: NVAL19/01 and GSK (NCT04449419).

Coping with the hospital environment during the COVID-19 pandemic: A qualitative study of the survivors' perspective during their stay at the ICU and inpatient ward

The COVID-19 pandemic has significantly affected the clinical practice of healthcare professionals. This study aimed to explore the perspectives of COVID-19 survivors regarding the healthcare they received during their stay in the Intensive Care Unit (ICU) and the inpatient COVID-19 ward.A qualitative case-study approach was implemented. Participants were recruited using non-probabilistic purposeful sampling strategy. Inclusion criteria included patients aged ≥18 years who received follow-up from the Pulmonology service at a Hospital in de North of Spain, were diagnosed with COVID-19 and bilateral pneumonia, and were admitted to the ICU before being transferred to a COVID-19 inpatient ward. Data was collected through in-depth interviews and researchers' field notes, and thematic analysis was performed. Techniques such as credibility, transferability, dependability, and confirmability were employed to ensure the trustworthiness of the data.A total of 25 individuals (six women) were included in the study. Three main themes emerged from the analysis: common challenges faced in both units, coping with the hospital stay, and developing strategies. Findings highlighted the need to improve information dissemination, individualize care, and enhance direct patient interaction. Moreover, the study shed light on the psychological impact of hospitalization and ICU experience, including feelings of loneliness, confinement, and the lack of memories from the ICU stay, as well as the influence of care and healthcare language. Finally, strategies such as keeping the mind occupied and maintaining self-discipline were identified as crucial during hospitalization. These findings provide valuable insights for healthcare professionals in delivering care to individuals with COVID-19 in the ICU and hospital ward settings
