RESUMEN

BACKGROUND: There is incomplete information regarding evolution of antibody titers against SARS-CoV-2 after a two-dose strategy vaccination with BNT162b2 in older adults in long-term care facilities (LTCFs) with frailty, disability, or cognitive impairment. We aimed to determine IgG antibody titer loss in older adults in LTCFs. METHODS: This is a multicenter longitudinal cohort study including 127 residents (90 females and 37 males) with a mean age of 82.7 years (range 65-99) with different frailty and disability profiles in two LTCFs in Albacete, Spain. Residents received two doses of BNT162b2 as per label, and antibody levels were determined 1 and 6 months after the second dose. Age, sex, previous history of coronavirus disease 2019 (COVID-19), comorbidity (Charlson Index), performance in activities of daily living (Barthel Index), frailty (FRAIL instrument), and cognitive status were assessed. RESULTS: The mean antibody titers 1 and 6 months after the second vaccine dose were 32,145 AU/ml (SD 41,206) and 6182 AU/ml (SD 13,316), respectively. Across all participants, the median antibody titer loss measured 77.6% (interquartile range [IQR] 23.8%). Notably, the decline of titers in individuals with pre-vaccination COVID-19 infection was significantly lower than in those without a history of SARS-CoV-2 infection (72.2% vs. 85.3%; p < 0.001). The median titer decrease per follow-up day was 0.47% (IQR 0.14%) and only pre-vaccination COVID-19 was associated with lower rate of antibody decline at 6 months (hazard ratio 0.17; 95% confidence interval 0.07-0.41; p < 0.001). Frailty, disability, older age, cognitive impairment, or comorbidity were not associated with the extent of antibody loss. CONCLUSIONS: Older adults in LTCFs experience a rapid loss of antibodies over the first 6 months after the second dose of BNT162b2 vaccine. Only pre-vaccination COVID-19 is associated with a slower rate of antibody decrease. Our data support immunization with a third dose in this vulnerable, high-risk population.

RESUMEN

BACKGROUND: Older adults are at the highest risk of severe disease and death due to COVID-19. Randomized data have shown that baricitinib improves outcomes in these patients, but focused stratified analyses of geriatric cohorts are lacking. Our objective was to analyze the efficacy of baricitinib in older adults with COVID-19 moderate-to-severe pneumonia. METHODS: This is a propensity score [PS]-matched retrospective cohort study. Patients from the COVID-AGE and Alba-Score cohorts, hospitalized for moderate-to-severe COVID-19 pneumonia, were categorized in two age brackets of age <70 years old (86 with baricitinib and 86 PS-matched controls) or ≥70 years old (78 on baricitinib and 78 PS-matched controls). Thirty-day mortality rates were analyzed with Kaplan-Meier and Cox proportional hazard models. RESULTS: Mean age was 79.1 for those ≥70 years and 58.9 for those <70. Exactly 29.6% were female. Treatment with baricitinib resulted in a significant reduction in death from any cause by 48% in patients aged 70 or older, an 18.5% reduction in 30-day absolute mortality risk (n/N: 16/78 [20.5%] baricitinib, 30/78 [38.5%] in PS-matched controls, p < 0.001) and a lower 30-day adjusted fatality rate (HR 0.21; 95% CI 0.09-0.47; p < 0.001). Beneficial effects on mortality were also observed in the age group <70 (8.1% reduction in 30-day absolute mortality risk; HR 0.14; 95% CI 0.03-0.64; p = 0.011). CONCLUSIONS: Baricitinib is associated with an absolute mortality risk reduction of 18.5% in adults older than 70 years hospitalized with COVID-19 pneumonia.

RESUMEN

BACKGROUND/OBJECTIVES: The safety and immunogenicity of the BNT162b2 coronavirus disease 2019 (COVID-19) vaccine in older adults with different frailty and disability profiles have not been well determined. Our objective was to analyze immunogenicity of the BNT162b2 mRNA COVID-19 vaccine in older adults across frailty and disability profiles. DESIGN: Multicenter longitudinal cohort study. SETTING AND PARTICIPANTS: A total of 134 residents aged ≥65 years with different frailty and disability profiles in five long-term care facilities (LTCFs) in Albacete, Spain. INTERVENTION AND MEASUREMENTS: Residents were administered two vaccine doses as per the label, and antibody levels were determined 21.9 days (SD 9.3) after both the first and second dose. Functional variables were assessed using activities of daily living (Barthel Index), and frailty status was determined with the FRAIL instrument. Cognitive status and comorbidity were also evaluated. RESULTS: Mean age was 82.9 years (range 65-99), and 71.6% were female. The mean antibody titers in residents with and without previous COVID-19 infection were 49,878 AU/ml and 15,274 AU/ml, respectively (mean difference 34,604; 95% confidence interval [CI]: 27,699-41,509). No severe adverse reactions were observed, after either vaccine dose. Those with prevaccination COVID-19 had an increased antibody level after the vaccine (B = 31,337; 95% CI: 22,725-39,950; p < 0.001). Frailty, disability, older age, sex, cognitive impairment, or comorbidities were not associated with different antibody titers. CONCLUSIONS: The BNT162b2 mRNA COVID-19 vaccine in older adults is safe and produces immunogenicity, independently of the frailty and disability profiles. Older adults in LTCFs should receive a COVID-19 vaccine.

RESUMEN

OBJECTIVE: Since obesity has been associated with a higher inflammatory burden and worse response to therapy in patients with chronic inflammatory rheumatic diseases (CIRD), we aimed to confirm the potential association between body mass index (BMI) and disease activity in a large series of patients with CIRDs included in the Spanish CARdiovascular in rheuMAtology (CARMA) registry. METHODS: Baseline data analysis of patients included from the CARMA project, a 10-year prospective study of patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA) attending outpatient rheumatology clinics from 67 Spanish hospitals. Obesity was defined when BMI (kg/m2) was >30 according to the WHO criteria. Scores used to evaluate disease activity were Disease Activity Score of 28 joints (DAS28) in RA, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in AS, and modified DAS for PsA. RESULTS: Data from 2234 patients (775 RA, 738 AS, and 721 PsA) were assessed. The mean ± SD BMI at the baseline visit were: 26.9 ± 4.8 in RA, 27.4 ± 4.4 in AS, and 28.2 ± 4.7 in PsA. A positive association between BMI and disease activity in patients with RA (ß = 0.029; 95%CI (0.01- 0.05); p = 0.007) and PsA (ß = 0.036; 95%CI (0.015-0.058); p = 0.001) but not in those with AS (ß = 0.001; 95%CI (-0.03-0.03); p = 0.926) was found. Disease activity was associated with female sex and rheumatoid factor in RA and with Psoriasis Area Severity Index and enthesitis in PsA. CONCLUSIONS: BMI is associated with disease activity in RA and PsA, but not in AS. Given that obesity is a potentially modifiable factor, adequate control of body weight can improve the outcome of patients with CIRD and, therefore, weight control should be included in the management strategy of these patients.

RESUMEN

OBJECTIVES: The Janus kinase (JAK) inhibitor baricitinib may block viral entry into pneumocytes and prevent cytokine storm in patients with SARS-CoV-2 pneumonia. We aimed to assess whether baricitinib improved pulmonary function in patients treated with high-dose corticosteroids for moderate to severe SARS-CoV-2 pneumonia. METHODS: This observational study enrolled patients with moderate to severe SARS-CoV-2 pneumonia [arterial oxygen partial pressure (PaO2)/fraction of inspired oxygen (FiO2) <200 mmHg] who received lopinavir/ritonavir and HCQ plus either corticosteroids (CS group, n = 50) or corticosteroids and baricitinib (BCT-CS group, n = 62). The primary end point was the change in oxygen saturation as measured by pulse oximetry (SpO2)/FiO2 from hospitalization to discharge. Secondary end points included the proportion of patients requiring supplemental oxygen at discharge and 1 month later. Statistics were adjusted by the inverse propensity score weighting (IPSW). RESULTS: A greater improvement in SpO2/FiO2 from hospitalization to discharge was observed in the BCT-CS vs CS group (mean differences adjusted for IPSW, 49; 95% CI: 22, 77; P < 0.001). A higher proportion of patients required supplemental oxygen both at discharge (62.0% vs 25.8%; reduction of the risk by 82%, OR adjusted for IPSW, 0.18; 95% CI: 0.08, 0.43; P < 0.001) and 1 month later (28.0% vs 12.9%, reduction of the risk by 69%, OR adjusted for IPSW, 0.31; 95% CI: 0.11, 0.86; P = 0.024) in the CS vs BCT-CS group. CONCLUSIONS: . In patients with moderate to severe SARS-CoV-2 pneumonia a combination of baricitinib with corticosteroids was associated with greater improvement in pulmonary function when compared with corticosteroids alone.

RESUMEN

Using AI, we identified baricitinib as having antiviral and anticytokine efficacy. We now show a 71% (95% CI 0.15 to 0.58) mortality benefit in 83 patients with moderate-severe SARS-CoV-2 pneumonia with few drug-induced adverse events, including a large elderly cohort (median age, 81 years). An additional 48 cases with mild-moderate pneumonia recovered uneventfully. Using organotypic 3D cultures of primary human liver cells, we demonstrate that interferon-α2 increases ACE2 expression and SARS-CoV-2 infectivity in parenchymal cells by greater than fivefold. RNA-seq reveals gene response signatures associated with platelet activation, fully inhibited by baricitinib. Using viral load quantifications and superresolution microscopy, we found that baricitinib exerts activity rapidly through the inhibition of host proteins (numb-associated kinases), uniquely among antivirals. This reveals mechanistic actions of a Janus kinase-1/2 inhibitor targeting viral entry, replication, and the cytokine storm and is associated with beneficial outcomes including in severely ill elderly patients, data that incentivize further randomized controlled trials.

RESUMEN

Objetivo: El paradigma actual en el tratamiento de la artritis reumatoide (AR) contempla el diagnóstico temprano y el uso precoz de fármacos modificadores de enfermedad (FAME) para alcanzar la remisión o baja actividad inflamatoria, lo cual, se conoce como «treat to target» (T2T). El objetivo del trabajo es desarrollar un indicador compuesto (IC) para evaluar la calidad asistencial en el manejo de los pacientes con AR atendiendo a la estrategia T2T y a otras recomendaciones generales para la atención de estos pacientes. Material y método: La construcción del IC siguió las fases: 1) selección de los criterios de calidad mediante un juicio de expertos; 2) priorización de los criterios, a partir de un Delphi con 20 expertos; 3) diseño de los indicadores de calidad, y 4) cálculo del IC ponderado. La fuente de información para el cálculo del IC son las historias clínicas de los pacientes con AR. Resultados: De los 37 criterios seleccionados, 12 necesitaron una segunda ronda Delphi. Se priorizaron 31 criterios, los cuales presentaron una mediana en relevancia y factibilidad, en las rondas Delphi, mayor o igual a 7,5, con un rango intercuartílico inferior a 3,5, y un grado de acuerdo (puntuación mayor o igual a 8) igual o superior al 80%. Conclusiones: El IC construido, consensuado y ponderado, permite evaluar la calidad asistencial de los pacientes con AR, en las Unidades de Reumatología de hospitales españoles, ofreciendo una medida resumen válida y fácilmente interpretable


Objective: The current guidelines in the treatment of rheumatoid arthritis (RA) include the early diagnosis and early use of disease modifying drugs to achieve remission or low disease activity level, known as "Treat to Target" (T2T). The objective of this study is to develop a composite indicator (CI) to evaluate the quality of care in the management of patients with RA, according to the T2T strategy and other general recommendations concerning the management of these patients. Material and method: The phases of the construction of the CI were: 1) selection of quality criteria through expert judgment; 2) prioritization of the criteria, according to relevance and feasibility, applying the Delphi methodology (two rounds) involving 20 experts; 3) design of quality indicators; and 4) calculation of the weighted CI, using the mean value in relevance and feasibility granted by the experts. The source of information for the calculation of the CI are the medical records of patients with RA. Results: Twelve criteria out of 37 required a second Delphi round. Thirty-one criteria were prioritized. These criteria presented a median in relevance and feasibility greater than or equal to 7.5, with an interquartile range of less than 3.5, and a level of agreement (score greater than or equal to 8) greater than or equal to 80%. Conclusions: The constructed CI allows us to evaluate the quality of care of patients with RA following the T2T strategy in the rheumatology units of Spanish hospitals, offering a valid and easily interpretable summary measure

RESUMEN

Granulomatosis with polyangiitis (GPA) is a systemic necrotizing granulomatosis vasculitis characterized by predilection to affect small- and medium-sized blood vessels and commonly affects the upper and lower respiratory tract and kidneys in most cases. Genital involvement is reported in <1% of cases in large cohorts and nearly all cases have been in the setting of multisystemic disease or during the course of the disease in patients already diagnosed as GPA. A case is presented of uncommon limited urogenital GPA in a 66-year-old woman with an irregular mass occupying urethra and vagina. The patient showed a good response after Corticoids and Methotrexate.

RESUMEN

Introducción. El objetivo del estudio es identificar los atributos físicos del síndrome de temor a caerse (STAC) en mayores con caídas previas. Metodología. Estudio observacional analítico sobre 183 sujetos mayores de 64 años que hayan sufrido al menos una caída en el último año, captados desde la consulta de geriatría del Complejo Hospitalario Universitario de Albacete. De ellos, 140 cumplían criterios de STAC, y los otros 43 no (grupo control). Como covariables se recogieron datos sociodemográficos, antropométricos, de comorbilidad y fármacos, situación funcional, función física, fragilidad, estado cognitivo y afectivo. Se determinó la masa muscular mediante bioimpedanciometría (BIA) y densitometría (DXA), la fuerza prensora mediante dinamómetro digital de JAMAR, la fuerza extensora (1RM) de miembros inferiores, la potencia muscular de miembros inferiores mediante el instrumento T-Force, la variabilidad de la marcha con el instrumento Gait-Rite, las alteraciones posturales mediante posturografía. Se analizará si el STAC se asocia con alteraciones físicas ajustado por las covariables de estudio. Resultados. Edad media 78,4 años, 147 mujeres. En 182 participantes se pudo realizar posturografía, en 146 se pudo determinar potencia muscular de piernas, en 117 se realizó DXA y en 165, BIA. El STAC se asoció a sexo femenino, estado de fragilidad, ánimo deprimido, riesgo social, fuerza y potencia muscular, función física, número de fármacos e hipotensión ortostática en la muestra global, pero al ajustar por sexo, solo la fragilidad, el ánimo deprimido y el consumo de fármacos se asociaron al STAC. Conclusiones. Se presenta el razonamiento, el diseño y la metodología del estudio FISTAC (AU)


Introduction. The aim of this study was to identify the physical determining factors of the Fear of Falling Syndrome (FoF) in older adults with a history of falls. Methods. An observational study was conducted on 183 subjects older than 64 years with a fall in the previous year, with data collected from the geriatrics outpatient clinic of the Complejo Hospitalario Universitario from Albacete, Spain. Sociodemographic and anthropometric data, as well as comorbidity, drugs usually taken, functional status, physical function, frailty, cognitive and affective status were collected. Muscle mass was measured using bioimpedancy meter (BIA), and densitometry (DXA), strength with digital hand-held JAMAR dynamometer and with a Leg-press machine, muscle potency with a T-Force instrument, gait variability with the Gait-Rite instrument, and postural stability with the Neurocom Balance Master posturograph were also determined. An analysis was performed to determine if the FoF is associated with physical impairments adjusted for the study covariates. Results. The study included 140 subjects with FoF, and 43 without it. The mean age was 78.4 years, and 147 were women. Posturography could be measured in 182 participants, DXA in 117, BIA in 165, and muscle potency in 146. FoF was associated with female sex, frailty, depressed mood, social risk, muscle strength and power, physical function, number of drugs used, and orthostatic hypotension in the overall sample. After adjusting for sex, only frailty, depressed mood, and number of drugs remained associated. Conclusions. Rationale, design, and methods of the FISTAC study are presented (AU)

RESUMEN

Las crioglobulinas son inmunoglobulinas que precipitan con el frío. Su presencia puede asociarse a un tipo de vasculitis denominada crioglobulinemia. Estas, especialmente las mixtas, se asocian a infecciones como el virus de la hepatitis C hasta en el 60-90% de los casos, aunque también se ha descrito su asociación a enfermedades del tejido conectivo, en las que suele tener un curso más agresivo. Se presenta el caso de una paciente con poliartritis seronegativa que desarrolló isquemia arterial aguda en el contexto de una crioglobulinemia y que ha respondido al tratamiento con rituximab (AU)


Cryoglobulins are immunoglobulins that precipitate at cold temperatures. Their presence can be related to a type of vasculitis referred to as cryoglobulinemia. This condition, especially mixed cryoglobulinemia, has been associated with viral infections like hepatitis C virus in 60%-90% of cases, but it has also been reported in relation to connective tissue diseases, usually resulting in a more severe course. We describe the case of a patient with seronegative polyarthritis who developed acute arterial ischemia in association with cryoglobulinemia, with a good response to rituximab therapy (AU)
