ABSTRACT

Objective: To evaluate the clinical response of patients with cystic fibrosis and primary ciliary dyskinesia after endoscopic sinus surgery at the Dr. Robert Reid Cabral Children's Hospital from September 2021 to February 2022. Methods: An ambispective, cross-sectional, observational case series study was conducted, where the study population was made up of patients with cystic fibrosis and primary ciliary dyskinesia at the Dr. Robert Reid Cabral children's hospital during the study period. Inclusion criteria: Patients older than 6 years with a confirmed diagnosis of cystic fibrosis and primary ciliary dyskinesia (Genetic test with 2 homozygous mutations, positives electrolytes in sweat), severe respiratory symptoms of CRS that did not improve with conventional treatment and underwent endoscopic surgery for sinuses. Results: Of a total of 41 patients, only 10 met the inclusion criteria, the most prevalent age range was 14 to 18 years. Both CF and PCD patients decreased the frequency of CRS symptoms. After ENC, there were discrete changes in lung function, and only patients with severe to moderate disease increased % of FEV1. Most of the patients did not require admission after surgery. The most common germ found in nasopharyngeal and sputum cultures in preoperative patients was Pseudomonas aeruginosa in 86%; after ESS there was a significant increase in MRSA colonization in both CF and PCD patients. More than 50% of postoperative patients improved their quality of life, so endoscopic sinus surgery is effective in this population in the treatment of chronic rhinosinusitis.


Objetivo: Evaluar la respuesta clínica de los pacientes con fibrosis quística y discinesia ciliar primaria posterior a la cirugía endoscópica de senos paranasales en el Hospital Infantil Dr. Robert Reid Cabral en el período septiembre 2021 a febrero 2022. Métodos: Se realizó un estudio observacional tipo serie de casos, de corte transversal y ambispectivo, donde la población estudiada estuvo conformada por los pacientes con fibrosis quística y discinesia ciliar primaria del hospital infantil Dr. Robert Reid Cabral en el período de estudio. Criterios de inclusión: Pacientes mayores de 6 años con diagnóstico confirmado de fibrosis quística y discinesia ciliar primaria (Prueba genética con 2 mutaciones homocigotas, electrolitos en sudor positivos), síntomas respiratorios severos de RSC que no mejoraron con tratamiento convencional y sometidos a la cirugía endoscópica de senos paranasales. Resultados: De un total de 41 pacientes, sólo 10 cumplieron con los criterios de inclusión, el rango de edad más prevalente fue de 14 a 18 años. Tanto los pacientes con FQ como los de DCP disminuyeron la frecuencia de los síntomas de RSC. Posterior a la CEN hubo cambios discretos en la función pulmonar, y sólo los pacientes con enfermedad grave a moderada aumentaron el % de FEV1. La mayoría de los pacientes no ameritaron ingresos posterior a la cirugía. El germen más común encontrado en los cultivos nasofaríngeo y esputo en los pacientes preoperatorios fue la Pseudomonas aeruginosa en el 86%, luego de la CEN hubo un aumento significativo de la colonización por MRSA tanto en los pacientes con FQ como en los de DCP. Más del 50% de los pacientes postquirúrgicos mejoraron su calidad de vida, por lo que la cirugía endoscópica de senos paranasales es efectiva en dicha población en el tratamiento de la rinosinusitis crónica.

ABSTRACT

Abstract Introduction: cystic fibrosis newborn screening must enable its earlier diagnosis, which may enhance outcomes. This study was a series case of delayed-diagnosis children submitted to cystic fibrosis newborn screening. Description: fourteen children were included; eight (57.1%) were due to false-negative screening, while six (42.9%) were due to processing errors. Two samples collected after 30 days of life were incorrectly classified as negative, and four infants with a positive test could not be located due to screening processing errors. Cystic fibrosis diagnosis was confirmed at a median (IQR) age of 5.3 (4.2-7.4) months. Poor nutritional status was the most prevalent clinical sign at diagnosis, being present in 78.6% of infants. The mean (SD) weight-for-length and length-for-age Z-scores were -3.46 (0.84) and -3.99 (1.16), respectively. Half of the children had Pseudo-Bartter syndrome, and 42.9% had breathing difficulties. Twelve children (85.7%) required hospitalization, with a median (IQR) length of stay of 17.0 (11.5-26.5) days. Discussion: newborn screening had some faults, from incorrect collections to inefficient active search. Early identification of these children in which screening was unsatisfactory is essential, emphasizing the importance and efforts to not miss them. In the case of a failed test, healthcare professionals must be prepared to recognize the main symptoms and signs of the disease.


Resumo Introdução: a triagem neonatal para fibrose cística deve contribuir para diagnóstico precoce e melhor prognóstico da doença. O estudo é uma série de casos com lactentes submetidos à triagem, porém com diagnóstico tardio da doença. Descrição: quatorze crianças foram incluídas; oito (57,1%) com triagem falso-negativo e seis (42,9%) com erros processuais na triagem neonatal. Duas amostras foram coletadas tardiamente, sendo incorretamente classificadas como negativas e quatro lactentes com triagem positiva não foram localizados, por erros na busca ativa. Confirmou-se o diagnóstico da fibrose cística com idade mediana (IIQ) de 5,3 (4,2-7,4) meses. O Comprometimento nutricional precoce foi o sinal clínico mais prevalente ao diagnóstico, presente em 78,6% das crianças. Os Z escores médios (SD) do peso para altura e altura para idade foram -3,46 (0,84) e -3,99 (1,16), respectivamente. Metade das crianças teve síndrome de Pseudo-Bartter e 42,9% dificuldade respiratória. Doze crianças (85,7%) precisaram hospitalização com tempo mediano de permanência de 17 dias. Discussão: a triagem neonatal para fibrose cística apresentou falhas, desde testes falso-negativos, coletas incorretas, até problemas com a busca ativa. Entretanto, o diagnóstico ágil é essencial e os profissionais de saúde devem reconhecer os sintomas e sinais precoces da doença, mesmo quando a triagem neonatal não for satisfatória.

ABSTRACT

ABSTRACT Objective: To evaluate the impact of COVID-19 social distancing recommendations on nutritional status, pulmonary function, and morbidity in patients with cystic fibrosis (CF). Methods: A retrospective cohort study including patients older than six years with a diagnosis of CF was performed. Demographic and clinical data, anthropometric measurements, pulmonary function, days of antibiotic use, and length of hospital stay were recorded. Variables were recorded at three time points relative to the baseline for implementation of social distancing measures: T-1 (14 months before implementation), T0 (baseline), and T1 (14 months after implementation). Delta (Δ) was calculated for each period: Δ1 (pre-pandemic T0-T-1) and Δ2 (pandemic T1-T0). Results: The study included 25 patients, with a mean age of 11.7±4.3 years. The mean forced expiratory volume in the first second (FEV1) was 85.6±23.6%, and body mass index (BMI) was 17.5±3.0 kg/m2. When comparing the two periods (Δ1 and Δ2), there was a significant increase in the FEV1/forced vital capacity (FVC) ratio (p=0.013) and in the forced expiratory flow between 25 and 75% of vital capacity (FEF25-75%) (p=0.037) in the pandemic period. There was also a significant reduction (p=0.005) in the use of antibiotics in the pandemic period compared with the pre-pandemic period. The Δ1 and Δ2 values did not differ significantly for BMI, FEV1, or length of hospital stay. Conclusions: COVID-19 social distancing recommendations had a positive impact (decrease) on morbidity (use of antibiotics) and small airway obstruction (FEF25-75%) in patients with CF.


RESUMO Objetivo: Avaliar o impacto das recomendações de medidas de distanciamento social por COVID-19 sobre estado nutricional, função pulmonar e morbidade em pacientes com fibrose cística (FC). Métodos: Estudo de coorte, retrospectivo, que incluiu pacientes com diagnóstico de FC e idade superior a seis anos. Foram registrados os dados demográficos, antropométricos, clínicos, de função pulmonar e o total de dias de uso de antibiótico e de hospitalizações. As variáveis foram registradas em três momentos relativos ao início das recomendações de distanciamento social: T-1 (14 meses antes), T0 (início das recomendações) e T1 (14 meses depois). Foram calculados deltas (Δ) para cada um dos períodos: Δ1 (pré-pandemia T0-T-1) e Δ2 (pandemia T1-T0). Resultados: Vinte e cinco pacientes, com média de idade de 11,7±4,3 anos, sendo 76% homozigotos para Δf508 e 28% colonizados por Pseudomonas aeruginosa, foram incluídos. A média do volume expiratório forçado no primeiro segundo (VEF1) foi de 85,6±23,6 (% do previsto) e o índice de massa corporal (IMC) foi de 17,5±3,0 kg/m2. Ao compararmos os períodos (Δ1 e Δ2), houve aumento significativo do VEF1/CVF (p=0,013) e do FEF25-75% (p=0,037) no período das recomendações de distanciamento. Também se observou redução significativa (p=0,005) do uso de antibióticos no período da pandemia em comparação ao período anterior a ela. Não houve diferenças significativas nos deltas para o IMC, VEF1 e dias de hospitalização. Conclusões: As recomendações de distanciamento social por COVID-19 tiveram impacto positivo (redução) sobre a morbidade (uso de antibióticos) e a obstrução de vias aéreas de menor calibre (FEF25-75%) em pacientes com FC.

ABSTRACT

Los moduladores de la proteína reguladora transmembrana de fibrosis quística (CFTR) tratan el defecto de esta proteína. El objetivo es describir la evolución de niños con fibrosis quística tratados con lumacaftor/ivacaftor. Se trata de una serie de 13 pacientes de 6 a 18 años con ≥ 6 meses de tratamiento. Se analizaron el volumen espiratorio forzado en el primer segundo (VEF1), puntaje Z del índice de masa corporal (IMC), antibioticoterapia/año, antes del tratamiento y durante 24 meses posteriores. A los 12 meses (9/13) y 24 meses (5/13), la mediana de cambio del porcentaje del predicho VEF1 (ppVEF1) fue de 0,5 pp [-2-12] y 15 pp [8,7-15,2], y del puntaje Z de IMC de 0,32 puntos [-0,2-0,5] y 1,23 puntos [0,3-1,6]. El primer año (11/13) la mediana de días de uso de antibiótico disminuyó de 57 a 28 (oral) y de 27 a 0 (intravenoso). Dos niños evidenciaron eventos adversos asociados.


Cystic fibrosis transmembrane regulator (CFTR) modulators treat defective CFTR protein. Our objective is to describe the course of children with cystic fibrosis treated with lumacaftor/ivacaftor. This is a case series of 13 patients aged 6 to 18 years with ≥ 6 months of treatment. Forced expiratory volume in the first second (FEV1), body mass index (BMI) Z-score, antibiotic therapy/year, before treatment and for 24 months after treatment were analyzed. At 12 months (9/13) and 24 months (5/13), the median change in the percent predicted FEV1 (ppFEV1) was 0.5 pp (-2­12) and 15 pp (8.7­15.2) and the BMI Z-score was 0.32 points (-0.2­0.5) and 1.23 points (0.3­1.6). In the first year, in 11/13 patients, the median number of days of antibiotic use decreased from 57 to 28 (oral) and from 27 to 0 (intravenous). Two children had associated adverse events.

ABSTRACT

La fibrosis quística, la segunda enfermedad genética más frecuente, es el resultado de una proteína de canal mutada, la CFTR, que secreta iones de cloro que fluidifican las secreciones. La esperanza de vida en los pacientes ha aumentado en años recientes gracias a mejoras en el tratamiento. No obstante, las complicaciones hepáticas son la tercera causa de muerte y la comprensión de su fisiopatología es aún deficiente. Se considera que la obstrucción biliar secundaria a la presencia de secreciones espesas conduce a la cirrosis. Sin embargo, el ácido ursodesoxicólico no ha modificado la historia natural. Además, la presencia de hipertensión portal en ausencia de cirrosis no puede ser explicada. Se ha propuesto el rol de la CFTR como modulador de tolerancia inmune, que explica la presencia de una inflamación portal persistente que culmina en fibrosis. El eje intestino-hígado tendría un rol importante en la presentación y la progresión de esta enfermedad


Cystic fibrosis is the second most common genetic disease in infancy. It is the result of a mutated channel protein, the CFTR, which secretes chloride ions, fluidifying secretions. Recent improvements in the treatment have increased life expectancy in these patients. Nevertheless, liver involvement remains the third cause of death. Unfortunately, our understating of the physiopathology is still deficient. Biliary obstruction secondary to the presence of thick secretions is considered to lead to cirrhosis. However, treatment with ursodeoxycolic acid has not changed the natural history. Furthermore, the presence of portal hypertension in the absence of cirrhosis cannot be explained. Recently, the role of CFTR as modulator of immune tolerance has been proposed, which could explain the presence of a persistent portal inflammation leading to fibrosis, and the gut-liver axis would also have a role in disease presentation and progression.

ABSTRACT

La investigación se realizó en el municipio Jiguaní, provincia de Granma, Cuba. Se inició, a partir de la limitada atención que reciben los educandos fibroquísticos en el contexto escolar; pues, en el sistema educativo cubano no hay evidencias de programas de actividades físico-terapéuticas que orienten la prescripción de ejercicios físicos y tengan en cuenta las posibilidades, potencialidades y necesidades de estos niños. La investigación tiene como objetivo elaborar un programa de actividades físico-terapéuticas, caracterizado por un enfoque integral físico-educativo que mejore la condición física orientada a la salud de educandos con fibrosis quística. Para su desarrollo, se efectuó un estudio correlacional, con diseño pre-experimental en el período comprendido entre septiembre 2019 y junio 2021. Se emplearon métodos teóricos, empíricos y estadístico-matemáticos, así como técnicas de investigación, entre ellos: analítico-sintético, hipotético-deductivo, sistémico estructural-funcional, revisión documental, observación estructurada, criterio de expertos, entrevista, triangulación metodológica y estadística descriptiva e inferencial. A partir de un muestreo intencional, se seleccionaron cuatro educandos con manifestaciones clínicas de las vías respiratorias, baja autoestima y escasa condición física, que representan el total de la población, para el 100 %, con una edad promedio de nueve años. En los resultados del experimento, mediante los indicadores evaluados con la implementación del programa de actividades físico-terapéuticas, se observaron cambios significativos en el 100 % de la muestra, con ello mejoró la condición física orientada a la salud en educandos con fibrosis quística.


A pesquisa foi realizada no município de Jiguaní, província de Granma, Cuba. Ela foi iniciada devido à atenção limitada que os alunos fibrocísticos recebem no contexto escolar, uma vez que no sistema educacional cubano não há evidências de programas de atividades físico-terapêuticas que orientem a prescrição de exercícios físicos e levem em conta as possibilidades, o potencial e as necessidades dessas crianças. O objetivo desta pesquisa é elaborar um programa de atividades físico-terapêuticas, caracterizado por um enfoque físico-educacional integral que melhore a condição física orientada para a saúde dos alunos com fibrose cística. Para seu desenvolvimento, foi realizado um estudo correlacional, com um desenho pré-experimental no período entre setembro de 2019 e junho de 2021. Foram utilizados métodos teóricos, empíricos e estatístico-matemáticos, bem como técnicas de pesquisa, incluindo: analítico-sintético, hipotético-dedutivo, estrutural-funcional sistêmico, revisão documental, observação estruturada, julgamento de especialistas, entrevista, triangulação metodológica e estatística descritiva e inferencial. A partir de uma amostragem intencional, foram selecionados quatro alunos com manifestações clínicas do trato respiratório, baixa autoestima e condição física ruim, representando 100% da população total, com idade média de nove anos. Nos resultados do experimento, por meio dos indicadores avaliados com a implementação do programa de atividades físico-terapêuticas, foram observadas mudanças significativas em 100% da amostra, melhorando assim a condição física voltada para a saúde dos alunos com fibrose cística.


The research was carried out in the Jiguaní municipality, Granma province, Cuba. It began, from the limited attention that fibrocystic students receive in the school context due to in the Cuban educational system there is no evidence of physical-therapeutic activity programs that guide the prescription of physical exercises and take into account the possibilities, potentialities and needs of these children. The objective of the research is to develop a program of physical-therapeutic activities, characterized by a comprehensive physical -educational approach that improves the health-oriented physical condition of students with cystic fibrosis. For its development, a correlational study was carried out, with a pre-experimental design in the period between September 2019 and June 2021. Theoretical, empirical and statistical-mathematical methods were used, as well as research techniques, including: analytical-synthetic, hypothetical-deductive, structural-functional systemic, documentary review, structured observation, expert judgment, interview, methodological triangulation and descriptive and inferential statistics. From an intentional sampling, four students with clinical manifestations of the respiratory tract, low self-esteem and poor physical condition were selected, representing the total population, for 100 %, with an average age of nine years. In the results of the experiment, through the indicators evaluated with the implementation of the program of physical-therapeutic activities, significant changes were observed in 100 % of the sample, thereby improving the health-oriented physical condition in students with cystic fibrosis.

ABSTRACT

Los avances tecnológicos y del conocimiento hicieron que un mayor número de pacientes con enfermedad crónica gastrointestinal pasen de ser atendidos por el pediatra al control por los médicos de adultos durante una de las etapas más vulnerables de la vida: la adolescencia. El Grupo de Trabajo de Transición del Comité de Gastroenterología de la Sociedad Argentina de Pediatría realizó una búsqueda de literatura exhaustiva y convocó a especialistas referentes del país, con el objeto de unificar los criterios basados en la evidencia y la experiencia. De esta manera, se proponen una serie de recomendaciones para todo el equipo de salud (pediatra, gastroenterólogo infantil, nutricionista, gastroenterólogo de adultos, psicólogo, enfermería), incluso para pacientes y familias, que faciliten el proceso de transición y optimicen el seguimiento, el control, la prevención de complicaciones y la calidad de vida de los pacientes con enfermedades crónicas gastrointestinales


Technological advances and the globalization of knowledge have led to a considerable increase in the number of patients with chronic gastrointestinal disease who transition from pediatric to adult care during one of the most vulnerable life stages: adolescence. The Transition Working Group of the Gastroenterology Committee of the Sociedad Argentina de Pediatría conducted an exhaustive literature search and summoned leading specialists in the most frequent chronic pathologies from all over the country to unify criteria based on evidence and experience. As a result, a series of recommendations are proposed for the whole health team (pediatrician, pediatric gastroenterologist, nutritionist, adult gastroenterologist, psychologist, and nurse) including patients and families, to facilitate the transition process, optimize follow-up, prevent complications, and improve the quality of life of patients with chronic gastrointestinal diseases.

ABSTRACT

Abstract Objective To assess the prevalence of GERD exclusively by means of multichannel intraluminal impedanciometry associated with pH monitoring (MIIpH) and compare it with respiratory symptoms in children with CF. To compare MIIpH with pHmetry alone to perform GERD diagnosis. Methods An analytical cross-sectional study was conducted with children diagnosed with CF who underwent MIIpH. Clinical and laboratory markers, including respiratory and digestive symptoms, were used for comparative analyses. High-resolution chest computed tomography was performed on patients with symptoms of chronic lung disease. Severity was classified according to the Bhalla score. Results A total of 29 children < 10 yo (18 girls) were evaluated; 19 of whom with physiological GER and 10 with GERD. Of the children with GERD, seven had predominantly acid GER, two acid+non-acid GER, and one non-acid GER. Three patients had GERD diagnosed only by MIIpH. Bhalla scores ranged from seven to 17.75 with no significant relationship with GERD. The number of pulmonary exacerbations was associated with a decrease in esophageal clearance regardless of the position in pHmetry and MIIpH. Conclusions The prevalence of GERD was 34% in children with CF. There was no association between respiratory disease severity and GER types. MIIpH detected 30% more patients with GERD than pHmetry.

ABSTRACT

Background: Several studies have demonstrated the utility of methylene blue (MB) to treat vasoplegic syndrome (VS), but some have cautioned against its routine use in lung transplantation with only two cases described in prominent literature. Cystic fibrosis patients commonly have chronic infections which predispose them to a systemic inflammatory syndrome-like vasoplegic response during lung transplantation. We present 13 cystic fibrosis patients who underwent lung transplantation and received MB for vasoplegic syndrome while on cardiopulmonary bypass, with or without inhaled pulmonary vasodilator therapy. Methods: Single?center, retrospective, case series analysis of cystic fibrosis patients who underwent lung transplant and received MB for vasoplegia. We defined the primary outcome as 30-day mortality, and secondary outcomes as primary graft failure, 1-year mortality, postoperative complications, and hemodynamic response to MB. Results: MB was associated with a significant increase in mean arterial pressure (MAP) (P < 0.001) in all patients, and 84.6% (11/13) of the patients had either a decrease or no change in vasopressor requirement. No patients developed acute primary graft dysfunction and there was 100% 30?day and 1?year survival. One patient required Extracorporeal membrane oxygenation (ECMO) for hypoxemia and 69% (9/13) of the patients had evidence of postoperative right ventricular dysfunction, but no patients required a right ventricular assist device. Conclusion: This case series demonstrates the effectiveness of MB in treating vasoplegia in cystic fibrosis patients during lung transplantation, without evidence of primary graft dysfunction, 30?day or 1?year mortality. The safety of MB regarding hypoxemia and increased pulmonary vascular resistance requires further investigation.

ABSTRACT

Abstract Objective: To analyze the performance of the cystic fibrosis (CF) newborn screening (NBS) program over its first five years in a Brazilian northeastern state. Methods: A population-based study using a screening algorithm based on immunoreactive trypsinogen (IRT)/IRT. Data were retrieved from the state referral screening center registry. The program performance was evaluated using descriptive indicators such as the results of an active search, coverage, newborn's age at the time of blood sampling, the time between sample collection and its arrival at the laboratory, and the child's age at diagnosis of disease. Results: The public CF screening program covered 82.6% of the 1,017,576 births that occurred, with an accumulated five-year incidence of 1:20,767 live births. The median (25th-75th) age at diagnosis was 3.5 (2.3-7.3) months. The sampling before 7 days of life for the first IRT (IRT1) increased between 2013 and 2017 from 42.2 to 48.3%. Around 5% of IRT1 samples and 30% of the second samples were collected after 30 days of life. In the first and second stages of screening, 23.6% and 19.9% of the infants, respectively, were lost to follow-up. In both stages of screening, the samples were retained at the health units for a median (25th-75th) of 9.0 (7.0-13.0) days. Conclusions: The coverage by the CF-NBS program was satisfactory as compared to other Brazilian state rates and the percentage of IRT1 samples collected within the first week of life increased progressively. However, time of samples retention at the health units, inappropriate sampling, inherent methodological problems, and loss of follow-up need to improve.

ABSTRACT

Abstract Objectives: Fecal calprotectin is an inflammatory marker used for monitoring intestinal diseases. It has been studied as a marker of intestinal inflammation in cystic fibrosis (CF), a multi-systemic genetic disease caused by alterations to the CFTR gene. Manifestations of the disease favor a systemic inflammation not limited to the respiratory tract, therefore, calprotectin is a non-invasive and effective diagnostic method. The aim of the study was to perform a systematic review of the literature with a qualitative synthesis of studies. Sources: The articles were selected from PubMed, Web of Science, Scielo and Lilacs. Summary of the findings: Nine studies were selected for that qualitative synthesis, one was a randomized clinical trial, and eight were case-control or cohort designs. Most studies have indicated that calprotectin is a marker of systemic inflammation in CF and not just intestinal inflammation. Calprotectin is an aid in monitoring inflammatory bowel conditions in patients with cystic fibrosis. Conclusion: Further studies should be conducted to investigate the role of this marker in the systemic inflammation of CF.

ABSTRACT

Mucociliary clearance system is the primary innate defense mechanism of the lung. It plays a vital role in protecting airways from microbes and irritants infection. Mucociliary clearance system, which is mediated by the actions of airway and submucosal gland epithelial cells, plays a critical role in a multilayered defense system via secreting fluids, electrolytes, antimicrobial and anti-inflammatory proteins, and mucus onto airway surfaces. Changes in environment, drugs or diseases can lead to mucus overproduction and cilia dysfunction, which in turn decrease the rate of mucociliary clearance and enhance mucus gathering. The dysfunction of mucociliary clearance system often occurs in several respiratory diseases, such as primary ciliary dysfunction, cystic fibrosis, asthma and chronic obstructive pulmonary disease, which are characterized by goblet cell metaplasia, submucosal gland cell hypertrophy, mucus hypersecretion, cilia adhesion, lodging and loss, and airway obstruction.

ABSTRACT

Nonobstructive azoospermia (NOA) is a severe condition in infertile men, and increasing numbers of causative genes have been identified during the last few decades. Although certain causative genes can explain the presence of NOA in some patients, a proportion of NOA patients remain to be addressed. This study aimed to investigate potential high-risk genes associated with spermatogenesis in idiopathic NOA patients by whole-exome sequencing. Whole-exome sequencing was performed in 46 male patients diagnosed with NOA. First, screening was performed for 119 genes known to be related to male infertility. Next, further screening was performed to determine potential high-risk causative genes for NOA by comparisons with 68 healthy male controls. Finally, risk genes with high/specific expression in the testes were selected and their expression fluctuations during spermatogenesis were graphed. The frequency of cystic fibrosis transmembrane conductance regulator (CFTR) gene pathogenic variant carriers was higher in the NOA patients compared with the healthy controls. Potential risk genes that may be causes of NOA were identified, including seven genes that were highly/specifically expressed in the testes. Four risk genes previously reported to be involved in spermatogenesis (MutS homolog 5 [MSH5], cilia- and flagella-associated protein 54 [CFAP54], MAP7 domain containing 3 [MAP7D3], and coiled-coil domain containing 33 [CCDC33]) and three novel risk genes (coiled-coil domain containing 168 [CCDC168], chromosome 16 open reading frame 96 [C16orf96], and serine protease 48 [PRSS48]) were identified to be highly or specifically expressed in the testes and significantly different in the 46 NOA patients compared with 68 healthy controls. This study on clinical NOA patients provides further evidence for the four previously reported risk genes. The present findings pave the way for further functional investigations and provide candidate risk genes for genetic diagnosis of NOA.

ABSTRACT

Abstract Background: Lung transplantation represents the definite treatment for CF patients with advanced-stage pulmonary disease. Recent major developments in the treatment of CF indicate the need for an evaluation of lung transplantation as the current best practice in end-stage disease. This systematic review was performed to evaluate the impact of lung transplantation on health-related quality of life in patients with CF. Methods: PubMed was searched for studies matching the eligibility criteria between January 2000 and January 2022. OVID (MEDLINE), Google Scholar, and EBSCOhost (EMBASE) as well as bibliographies of included studies were also reviewed. Applying predetermined eligibility criteria, the included studies were selected. Predetermined forms were used to conduct a quality appraisal and implement data tabulation. Results were synthesized by narrative review. This systematic review was prospectively registered in the PROSPERO register (CRD 42022341942). Results: Ten studies (1494 patients) were included. Lung transplantation results in improvements in HRQoL in CF patients relative to their baseline waitlisted state. Up to five years postoperatively CF patients retain their HRQoL at levels similar to the general population. There are several modulating factors that impact HRQoL outcomes in CF patients post-LTx. Compared to lung recipients with other diagnoses CF patients achieve either greater or equal levels of HRQoL. Conclusion: Lung transplantation conveys improved HRQoL to CF patients with the advanced-stage pulmonary disease for up to five years, and to levels comparable to the general population and non-waitlisted CF patients. This systematic review quantifies, using current evidence, the improvements in HRQoL gained by CF patients following lung transplantation.

ABSTRACT

ABSTRACT Cystic Fibrosis (CF) is a genetic disease that reduces quality of life. Lung transplantation (LTx) is a strategy for end-stage lung disease treatment in CF. Pulmonary rehabilitation (PR) in LTx is effective, however, only one study has determined its effectiveness in children, and most studies have not included CF exclusively. Thus, reports showing components for PR protocols and outcomes not considered in previous studies of PR in LTx due to CF in children are still needed. To report this case, written informed assent and consent of patient and parent were obtained. Ethical Requirement was formally waived by the institution. A 12-year-old patient with CF was referred to PR due to LTx. A general and respiratory training was conducted daily for six months (pre) and two years (post) the transplantation, with the parents' full support. General training included treadmill and cycle ergometer use and upper limbs exercises. Respiratory protocol included inspiratory training and respiratory physical therapy. We observed improvements in pulmonary function, exercise capacity, inspiratory muscle strength, and quality of life, including school functioning, with progress maintenance after 2.5 years of continuous intervention. This case presents a PR protocol pre- and post-LTx with good long-term results. These components for treatment protocols and outcomes may be useful to consider in clinical interventions or future investigations.


RESUMO Fibrose cística (FC) é uma doença genética que reduz a qualidade de vida. O transplante pulmonar (LTx) é uma estratégia para o tratamento de doenças pulmonares em fase terminal na FC. A reabilitação pulmonar (PR) no LTx é eficaz, porém apenas um estudo determinou sua eficácia em crianças, e outros estudos não incluíram a FC exclusivamente. Portanto, relatórios que mostram componentes para protocolos e resultados de RP, não considerados em estudos anteriores de RP em LTx devido à FC em crianças, ainda são necessários. Assim, descreve-se o caso de um paciente de 12 anos com FC encaminhado para RP devido à LTx. Foi obtido o consentimento informado e por escrito do paciente e dos pais. O requisito ético foi formalmente renunciado pela instituição. Um treinamento geral e respiratório foi realizado por seis meses antes e dois anos após a LTx, diariamente, com total apoio dos pais. O treinamento geral incluiu esteira, cicloergômetro e exercícios para os membros superiores. O protocolo respiratório incorporou treinamento inspiratório e fisioterapia respiratória. Foram observadas melhorias na função pulmonar, capacidade de exercício, força muscular inspiratória e qualidade de vida, incluindo o funcionamento escolar, com manutenção dos avanços após 2,5 anos de intervenção contínua. O caso apresenta um protocolo de RP pré e pós-LTx com bons resultados a longo prazo. Os componentes para protocolos de tratamento e resultados encontrados podem ser úteis para intervenções clínicas ou investigações futuras.


RESUMEN La fibrosis quística (FQ) es una enfermedad genética que reduce la calidad de vida de los afectados. El trasplante de pulmón (LTx) es una estrategia para el tratamiento de enfermedades pulmonares en fase terminal en FQ. La rehabilitación pulmonar (RP) en el LTx es eficaz, aunque solo un estudio evaluó su eficacia en niños, y otros estudios no han tratado exclusivamente de FQ. Por lo tanto, se necesitan informes que contengan elementos de los protocolos y de los resultados de RP y que no habían sido considerados en los estudios anteriores sobre RP en LTx por FQ pediátrica. Así se describe el caso del paciente de 12 años de edad con FQ que fue remitido a RP debido a LTx. Para ello, se obtuvieron el consentimiento informado y el consentimiento por escrito del paciente y sus padres. La institución renunció formalmente a los requisitos éticos. Se realizó entrenamiento general y respiratorio durante seis meses antes de LTx y dos años después de LTx, diariamente, con apoyo de los padres. El entrenamiento general incluyó cinta de correr, cicloergómetro y ejercicios para extremidades superiores. El protocolo respiratorio incluía entrenamiento inspiratorio y fisioterapia respiratoria. Se observaron mejorías en la función pulmonar, capacidad de ejercicio, fuerza muscular inspiratoria y calidad de vida del participante, incluida en la limitación de actividades, con mantenimiento de los logros tras 2,5 años de la intervención continua. El caso del estudio presentó un protocolo de RP pre- y post-LTx con buenos resultados a largo plazo. Estos elementos de los protocolos de tratamiento y los resultados encontrados pueden ser útiles en las intervenciones clínicas o en futuras investigaciones.

ABSTRACT

El uso de moduladores de CFTR en pacientes con fibrosis quística post trasplante pulmonar es un tema todavía controversial. Varias publicaciones reportan los beneficios del modulador elexacaftor/tezacaftor/ivacaftor en los síntomas extrapulmonares de la fibrosis quística, especialmente enfermedad sinusal, síntomas gastrointestinales y diabetes. Un número alto de pacientes debe discontinuar el tratamiento por mala tolerancia, sin embargo, no se describen interacciones de importancia con el tratamiento inmunosupresor. Se debe considerar para su uso los riesgos versus beneficios en forma individual en cada paciente.


The use of CFTR modulators in patients with cystic fibrosis after lung transplantation is still a controversial issue. Several publications report the benefits of the use of the modulator elexacaftor/tezacaftor/ivacaftor on extrapulmonary symptoms of cystic fibrosis, especially sinus disease, gastrointestinal symptoms and diabetes. A high number of patients must discontinue treatment due to poor tolerance; however, no significant interactions with immunosuppressive treatment have been described. The individual risk-benefit of each patient should be considered for its use.

ABSTRACT

Abstract Background With improvements in care for people with Cystic Fibrosis (pwCF), total survival after Lung Transplantation (LTx) will be longer. Therefore, this population's up-to-date analysis of late-onset post-transplant metabolic and vascular complications will be more relevant in current clinical practice. Methods We studied 100 pwCF who underwent an LTx between 2001 and 2020 at the University Medical Centre Utrecht, the Netherlands. The median age at transplant was 31 years and 55 percent was male. We assessed survival, the prevalence of metabolic complications (diabetes, renal damage, dyslipidemia, and metabolic syndrome), and vascular complications (hypertension, heart rhythm disease, micro-, and macrovascular disease). In addition, differences in risks for developing complications based on sex and overall survival were analyzed. Results The prevalence of macrovascular disease raised to 15.9 percent 15 years post-LTx. The prevalence of diabetes increased from 63 percent at LTx to over 90 percent 15 years post-LTx and the prevalence of dyslipidemia increased from 21 percent to over 80 percent. Survival 1-, 2-, 5-, and 10 years post-transplant were 84, 80, 76, and 58 percent respectively. No significant differences were found based on sex. Conclusion This study shows that the prevalence of cardiovascular risk factors increases after LTx for CF, potentially leading to major complications. These data emphasize the necessity of regular check-ups for metabolic and vascular complications after LTx with specific attention to renal damage. Early recognition of these complications is crucial and will lead to earlier intervention, which could lead to improved prognosis after lung transplantation.
