Basic action protocol for the outpatient management of chronic heart failure of the Spanish society of internal medicine.

Chronic heart failure (CHF) represents a challenge for the healthy system due to its high prevalence, high burden of morbidity and mortality, and high consumption of health resources. To address this problem, it is necessary to develop efficient management strategies that include both hospital care and outpatient care. The primary objective is to stabilize the patient and prevent decompensation, with the consequent improvement in quality of life, reduction in hospital admissions and emergency department care, and, consequently, reduction in healthcare costs. In this context, the heart failure and atrial fibrilation working group of the Spanish Society of Internal Medicine has developed a protocol for the management of outpatient CHF, that addresses, from the perspective of Internal medicine, all the problems suffered by the patient with CHF. This protocol aims to optimize pharmacological treatment, control cardiovascular risk factors and various comorbidities, educate the patient and their environment about the disease, promote adherence to treatment and stablish follow-up adapted to their condition.

The RICA-2 registry: design and baseline characteristics of the first 1,000 patients.

BACKGROUND AND OBJECTIVE: Heart failure (HF) is a syndrome of epidemic proportions and one of the main reasons for hospital admission. Patient registries provide real-world clinical practice information which is complementary to clinical trials. RICA-2 is a registry of the Spanish Society of Internal Medicine. Its main goal is to know the clinical and epidemiological characteristics and prognostic factors of patients with HF treated in Internal Medicine Departments. The objective of this study is to present the design of the RICA-2, the baseline characteristics of the first 1000 patients included and their comparison with those of the historical cohort of the RICA registry. METHODS: Observational, multicentre and prospective study of patients with HF with the following inclusion criteria: age equal to or greater than 18 years old, diagnosis of HF according to the European Guidelines, indistinct inclusion in decompensation or stable phase, of patients with de novo HF or chronic HF, regardless of left ventricular ejection fraction, aetiology and comorbidities. RESULTS: RICA-2 patients have advanced age (83 years old) and 51% are women. The comorbidity burden is higher than in the RICA registry (5 points in the Charlson comorbidity index), with predominating chronic decompensated HF (74%), hypertensive aetiology (39%) and preserved ejection fraction (52%). Most patients are pre-frail or vulnerable and are at risk of malnutrition. CONCLUSION: The RICA-2 represents a contemporary cohort of patients that will provide us with clinical, epidemiological and prognostic information on patients with acute and chronic HF treated in Internal Medicine.

Real-World Clinical, Psychosocial and Financial Burden of Atopic Dermatitis: Results from the Spanish Cohort of the MEASURE-AD Trial. / Carga clínica, psicosocial y económica de la dermatitis atópica en vida real: resultados de la cohorte española del estudio MEASURE-AD.

BACKGROUND: Atopic dermatitis (AD) is one of the most prevalent skin diseases, but there are numerous knowledge gaps surrounding the impact this disease has on quality of life (QoL), mental health, and out-of-pocket expenses involved in the management of AD. The available scientific evidence on the multidimensional burden of AD is usually based on studies with measures reported by patients themselves. METHODS: In this context, the MEASURE-AD trial was developed as a cross-sectional, multicenter, multinational trial using patient- and physician-reported measures to characterize the multidimensional burden of AD in adults with moderate-to-severe AD. RESULTS: This paper presents the results of the Spanish cohort. We found that Spanish adults with moderate-to-severe AD and high EASI score (21.1-72) had a significantly increased disease burden, high severity of symptoms such as itch and sleep disturbances, impaired mental health and QoL, higher use of health care resources, and more out-of-pocket expenses than patients with low EASI scores (0-7 or 7.1-21). CONCLUSIONS: This study provides information to better understand disease burden, and identify aspects to be improved in the management of AD.

Consensus on the diagnostic algorithm for chronic nodular prurigo. / Consenso sobre el algoritmo diagnóstico del prurigo crónico nodular.

Chronic nodular prurigo (CNP) is a chronic dermatological disease characterized by the presence of chronic pruritus and pruritic nodular lesions. The aim of this study was to reach consensus among a group of experts based on a non-systematic literature review and an algorithm for the clinical diagnosis of CNP. The resulting algorithm is structured in 3 blocks: 1) early identification of the patient with a possible diagnosis of CNP; 2) diagnosis and assessment of CNP; and 3) categorization of CNP (identification of the underlying causes or associated comorbidities). We believe that this clinical algorithm can facilitate the correct diagnosis of patients with CNP. Additionally, it raises awareness on the need for a multidisciplinary approach and specific treatment of CNP, steps of paramount importance to make better therapeutic decisions.

Clinical suspicion, diagnosis and management of cardiac amyloidosis: update document and executive summary.

In recent years, the interest in cardiac amyloidosis has grown exponentially. However, there is a need to improve our understanding of amyloidosis in order to optimise early detection systems. Therefore, it is crucial to incorporate solutions to improve the suspicion, diagnosis and follow-up of cardiac amyloidosis. In this sense, we designed a tool following the different phases to reach the diagnosis of cardiac amyloidosis, as well as an optimal follow-up: a) clinical suspicion, where the importance of the "red flags" to suspect it and activate the diagnostic process is highlighted; 2) diagnosis, where the diagnostic algorithm is mainly outlined; and 3) follow-up of confirmed patients. This is a practical resource that will be of great use to all professionals caring for patients with suspected or confirmed cardiac amyloidosis, to improve its early detection, as well as to optimise its accurate diagnosis and optimal follow-up.

Recommendations on the Use of Moisturizing Products Prepared by Spanish Dermatologists Using the Delphi Method. / Recomendaciones sobre el uso de productos hidratantes elaboradas por dermatólogos españoles mediante el método Delphi.

BACKGROUND AND OBJECTIVE: Moisturizing products are widely used in conditions affecting skin hydration. However, the lack of scientific evidence leads to discrepancies and great variability in the recommendations used by different health professionals. The aim of this consensus document is to generate recommendations based on the evidence and experience of dermatologists to unify and facilitate the use of moisturizing products in the routine clinical practice. MATERIALS AND METHODS: A 49-statement questionnaire on moisturizing products was prepared and, then, arranged in 5 blocks: 1) concept; 2) characteristics, 3) frequency and quantity, 4) product use and areas of application, and 5) special populations. Twenty-two expert dermatologists in the management of patients with eczema answered to the survey using a 2-round Delphi methodology (adding an item on the 2nd round). RESULTS: Consensus was reached on 27 statements (54%), most (n=23) via agreement. The highest level of agreement was reached in the blocks on quantity, product use and areas of application (77.8%), followed by the blocks on characteristics (73%) and frequency (62.5%). Regarding the blocks on concept and special populations, the level of consensus on the items proposed was 37.5% and 10%, respectively. Consensus on the use of emollients for xeroderma (71%) was higher vs atopic dermatitis (64%) and inflamed skin (33.3%). CONCLUSIONS: Consensus recommendations can help all prescribers and improve the available evidence regarding their use.

Epidemiological, Clinical, and Allergic Profile of Psoriatic Patients. Evaluation of the Spanish Registry of Contact Dermatitis and Cutaneous Allergy (REIDAC). / Perfil epidemiológico, clínico y alérgico en pacientes con psoriasis. Evaluación del Registro Español de Dermatitis de Contacto (REIDAC).

BACKGROUND: Psoriasis is a chronic inflammatory dermatosis whose clinical and topographic distribution requires differential diagnosis, or the possible association with allergic contact dermatitis (ACD), requiring patch testing (PT) as part of the diagnostic procedure. OBJECTIVES: To describe the epidemiological, clinical, and allergic profile of patients with a primary or secondary diagnosis of psoriasis undergoing PT and compare them with patients with a diagnosis of ACD at the end of the diagnostic process. METHODS: Cross-sectional study with data from REIDAC from 2018 through 2023 of selected patients with a diagnosis of psoriasis and/or ACD. RESULTS: A total of 11 502 patients were included, 513 of whom had been diagnosed with primary or secondary psoriasis, 3640 with ACD, and 108 with both diseases. Men were more predominant in the groups of patients with psoriasis, psoriasis+ACD, and lesions were more predominantly seen in the hands with little association with atopic factors vs the ACD group. The rate of positivity in PT to the 2022 Spanish battery of allergens was lower in the group with psoriasis only in 27% of the patients. The most common allergens found in the psoriasis group were also the most common ones found in the overall ACD population. CONCLUSIONS: Overall, 36.2% of psoriatic patients tested positive in PT to the 2022 Spanish battery of allergens, which proved that this association is not uncommon. Overall, psoriatic patients had a higher mean age, were more predominantly men, and showed more hand involvement.

Resumen ejecutivo de la actualización 2023 del consenso de actuación básica durante el ingreso hospitalario por insuficiencia cardiaca aguda / Executive summary of the 2023 update on the consensus regarding basic conduct during hospital admission for patients with acute heart failure

La insuficiencia cardiaca aguda (ICA) está asociada a una importante morbimortalidad, constituyendo la primera causa de hospitalización en mayores de 65 años en nuestro país. Las principales recomendaciones recogidas son: 1) al ingreso, se recomienda realizar una evaluación integral, considerando el tratamiento habitual y comorbilidades, ya que condicionan el pronóstico; 2) en las primeras horas de atención hospitalaria, el tratamiento descongestivo es prioritario, y se recomienda un abordaje terapéutico diurético precoz y escalonado en función de la respuesta; 3) durante la fase estable, se recomienda considerar el inicio y/o titulación del tratamiento con fármacos basados en la evidencia, es decir, sacubitrilo/valsartán o inhibidores de la enzima convertidora de angiotensina/antagonistas de los receptores de angiotensina II, betabloqueantes, antialdosterónicos e inhibidores SGLT2, y 4) en el momento del alta hospitalaria, es recomendable utilizar un listado —tipo check-list— para optimizar el manejo del paciente hospitalizado e identificar las opciones más eficientes para mantener la continuidad de cuidados tras el alta (AU)

Background In recent years, remarkable improvements in our understanding of atopic dermatitis (AD) have revolutionized treatment perspectives, but access to reliable data from clinical practice is essential. Materials and method The Spanish Atopic Dermatitis Registry, BIOBADATOP, is a prospective, multicenter database that collects information on patients of all ages with AD requiring systemic therapy with conventional or novel drugs. We analyzed the registry to describe patient characteristics, diagnoses, treatments, and adverse events (AEs). Results We studied data entries for 258 patients who had received 347 systemic treatments for AD. Treatment was discontinued in 29.4% of cases, mostly due to a lack of effectiveness (in 10.7% of cases). A total of 132 AEs were described during follow-up. Eighty-six AEs (65%) were linked to a systemic treatment, most commonly dupilumab (39AEs) and cyclosporine (38AEs). The most common AEs were conjunctivitis (11patients), headache (6), hypertrichosis (5), and nausea (4). There was 1severe AE (acute mastoiditis) associated with cyclosporine. Conclusions Initial findings on AEs from the Spanish BIOBADATOP registry are limited by short follow-up times precluding comparisons or calculation of crude and adjusted incidence rates. At the time of our analysis, no severe AEs had been reported for novel systemic therapies. BIOBADATOP will help answer questions on the effectiveness and safety of conventional and novel systemic therapies in AD (AU)

Utilidad pronóstica de la presión de pulso en pacientes con insuficiencia cardiaca con fracción de eyección preservada: Registro RICA / Prognostic utility of pulse pressure in patients with heart failure with preserved ejection fraction: The RICA Registry

Background and aims The prognostic role of pulse pressure (PP) in heart failure (HF) patients with preserved left ventricular ejection fraction (LVEF) is not well understood. Our aim was to evaluate it in acute and stable HF. Material and methods This work is a retrospective observational study of patients included in the RICA registry between 2008 and 2021. Blood pressure was collected on admission (decompensation) and 3 months later on an outpatient basis (stability). Patients were categorized according to whether the PP was greater or less than 50mmHg. All-cause mortality was assessed at 1year after admission. Results A total of 2291 patients were included, with mean age 80.1±7.7 years. 62.9% were women and 16.7% had a history of coronary heart disease. In the acute phase, there was no difference in mortality according to PP values, but in the stable phase PP<50mmHg was independently associated with all-cause mortality at 1-year follow-up (HR 1.57, 95% CI 1.21−2.05, p=0.001), after adjusting for age, sex, New York Heart Association functional class, previous HF, chronic kidney disease, valvular heart disease, cerebrovascular disease, score on the Barthel and Pfeiffer scales, hemoglobin and sodium levels. Conclusion Low stable-phase PP was associated with increased all-cause mortality in HF patients with preserved LVEF. However, PP was not useful as a prognostic marker of mortality in acute HF. Further studies are needed to assess the relationship of this variable with mortality in HF patients (AU)

Antecedentes y objetivo El papel pronóstico de la presión de pulso (PP) en pacientes con insuficiencia cardiaca (IC) con fracción de eyección de ventrículo izquierdo (FEVI) preservada no es bien conocido. Nuestro objetivo fue evaluarlo en fases de descompensación y de estabilidad. Material y métodos Estudio observacional retrospectivo de pacientes incluidos en registro RICA entre 2008 y 2021. La presión arterial se recogió al ingreso (descompensación) y a los 3 meses (estabilidad). Se calculó la PP y los pacientes se categorizaron según PP mayor/igual vs menor de 50mmHg. Se evaluó la mortalidad por todas las causas al año del ingreso. Resultados Se incluyeron 2.291 pacientes, con edad media 80,1±7,7 años. El 62,9% eran mujeres y un 16,7% tenían antecedentes de cardiopatía isquémica. En fase aguda, no hubo diferencias en la mortalidad según los valores de PP, pero en fase estable una PP<50mmHg se asoció de forma independiente con mortalidad por todas las causas al año de seguimiento (HR 1,57, IC 95% 1,21-2,05; p=0,001), una vez controlado por edad, sexo, NYHA, IC previa, enfermedad renal crónica, valvulopatía, enfermedad cerebrovascular, Barthel, Pfeiffer, hemoglobina y sodio. Conclusione Una PP baja en fase estable se asoció con mayor mortalidad por todas las causas en pacientes con IC con FEVI preservada. Sin embargo, la PP no demostró ser un factor pronóstico en fase de descompensación. Se necesitan más estudios que valoren la relación de esta variable con la mortalidad en los pacientes con IC (AU)

Uso del dermatoscopio en la lectura de pruebas epicutáneas: ¿qué puede aportar? / Dermoscopy in Patch Testing: How Can It Help?

La lectura de los parches de pruebas epicutáneas no es sencilla, presenta una gran variabilidad inter- e intraobservador y requiere experiencia. En ocasiones es realmente difícil determinar si se trata de una reacción alérgica de intensidad leve o si estamos ante una reacción irritativa. Recientemente se han publicado algunos trabajos que han estudiado las características dermatoscópicas de las distintas reacciones que se producen tras realizar pruebas epicutáneas. La característica dermatoscópica más frecuentemente observada en los parches alérgicos es el eritema homogéneo, si bien vasos puntiformes, vesículas o costras y áreas amarillo-anaranjadas también parecen indicar una reacción alérgica, guardando cierta similitud con lo observado en patología inflamatoria como en el eccema. Por otro lado, en cuanto a las reacciones irritativas, el patrón más indicativo sería el «patrón del poro», acompañado de eritema perifolicular. Estos hallazgos dermatoscópicos pueden ser de utilidad al clínico en su toma de decisiones ante una reacción dudosa (AU)

Interpreting patch test reactions is not easy. It requires experience and is characterized by high intraobserver and interobserver variability. It can sometimes be truly difficult to discern between a weak allergic reaction and an irritant reaction. A number of recent studies have investigated the dermoscopic features of patch test reactions. Homogeneous erythema is the main feature observed in patients with a positive allergic reaction, although dotted vessels, vesicles, crusts and yellow-orange areas may also provide clues. These features are somewhat similar to those observed in inflammatory conditions, such as eczema. In patients with an irritant reaction, the most common dermoscopic findings are the pore reaction pattern and perifollicular erythema. Dermoscopy could be useful for establishing a diagnosis in the case of doubtful patch test reactions (AU)
