RESUMO
Los trastornos del sueño son comunes en pacientes con fibrosis quística y afectan significativamente su calidad de vida. Estos pacientes experimentan una reducción en la calidad del sueño, hipoxemia nocturna, alteraciones en la polisomnografía y una alta prevalencia de síndrome de apneahipopnea obstructiva del sueño. Los factores que contribuyen a estas alteraciones incluyen la tos crónica, los síntomas digestivos, las rutinas de tratamiento y, posiblemente, la disfunción del canal CFTR. Sin embargo, el impacto de los moduladores de CFTR en la mejora de los trastornos del sueño aún no está claramente establecido, lo que resalta la necesidad de más estudios para comprender mejor su papel en el manejo del sueño en pacientes con fibrosis quística.
Sleep disorders are common in patients with cystic fibrosis and significantly affect their quality of life. These patients experience reduced sleep quality, nocturnal hypoxemia, polysomnography alterations, and a high prevalence of obstructive sleep apnea-hypopnea syndrome. Contributing factors include chronic cough, digestive symptoms, treatment routines, and potentially CFTR channel dysfunction. However, the impact of CFTR modulators on improving sleep disorders is not yet clearly established, highlighting the need for further studies to better understand their role in sleep management in cystic fibrosis patients.

La enfermedad hepática relacionada con fibrosis quística se observa en el 10% de las personas portadoras de la enfermedad. La terapia con moduladores ha mejorado la morbimortalidad, pero teniendo en cuenta que presentan efectos secundarios infrecuentes es necesario monitorizar. Se analiza el algoritmo propuesto por Eldredge et al, que sugiere las decisiones a tomar basado en el resultado de perfil hepático y su aplicación en la práctica clínica.
Cystic fibrosis-related liver disease is seen in 10% of people with the disease. Therapy with modulators has improved morbidity and mortality, but taking into account that they present infrequent side effects, monitoring is necessary. The algorithm proposed by Eldredge et al is analyzed, which suggests the decisions to be made based on the liver profile result and its application in clinical practice.

Se presenta el caso de un niño de 3 años con diagnóstico de asma, rinitis alérgica, características craneofaciales dismórficas e infecciones respiratorias altas y bajas recurrentes, manejado como asma desde un inicio. Como parte del estudio de comorbilidades, se decide realizar una prueba del sudor que sale en rango intermedio y más tarde se encuentra una mutación, donde se obtiene un resultado positivo para una copia que se asocia a fibrosis quística. Se revisará el caso, así como el diagnóstico, clínica y tratamiento del síndrome metabólico relacionado con el regulador de conductancia transmembrana de fibrosis quística (CRMS).
We present the case of a 3-year-old boy with a diagnosis of asthma, allergic rhinitis, dysmorphic craniofacial characteristics and recurrent upper and lower respiratory infections, managed as asthma from the beginning. As part of the study of comorbidi-ties, it was decided to carry out a sweat test that came out in the intermediate range and later one mutation was found, where a positive result was obtained for a copy that is associated with cystic fibrosis. The case will be reviewed, as well as the diagnosis, symptoms and treatment of the metabolic syndrome related to the cystic fibrosis trans-membrane conductance regulator (CRMS).

Se presenta el caso de un paciente masculino de 15 años con diagnóstico de fibrosis quística. Este desarrolló una sintomatología caracterizada por tos húmeda, no cianozante ni emetizante, sin un patrón temporal específico. Asociado a esto, nuevas lesiones nodulares bilaterales fueron identificadas en una tomografía de tórax. El abordaje diagnóstico incluyó una broncoscopia y la toma de un lavado broncoalveolar, que identificó la presencia de un microorganismo micótico poco común: Penicillium spp. Se inició tratamiento con voriconazol oral durante 14 días, resultando en una mejora clínica y radiológica significativa. El cultivo de expectoración posterior mostró un resultado negativo para Penicillium spp. Aunque la incidencia de exacerbaciones pulmonares causadas por agentes micóticos en pacientes con fibrosis quística es relativamente baja, se observa un incremento gradual, posiblemente relacionado con el uso prolongado de antimicrobianos de amplio espectro. La importancia de reportar este caso radica en el papel incierto que estos microorganismos juegan en la progresión del daño pulmonar, subrayando la necesidad de un seguimiento a mediano y largo plazo en estos pacientes.
This report discusses a 15-year-old male patient diagnosed with cystic fibrosis who developed clinical symptoms characterized by productive cough, not associated with cyanosis or vomiting, and without a specific time pattern. Associated with these symptoms, new bilateral nodular lesions were identified in a chest CT scan. Diagnostic approach included bronchoscopy and bronchoalveolar lavage, which identified a rare fungal organism: Penicillium spp. Treatment with oral voriconazole for 14 days was initiated, resulting in significant clinical and radiological improvement. Subsequent sputum culture showed a negative result for Penicillium spp. Although the incidence of pulmonary exacerbations caused by fungal agents in patients with cystic fibrosis is relatively low, there is a gradual increase, possibly related to the prolonged use of broad-spectrum antimicrobials. The importance of reporting this case lies in the uncertain role these organisms play in the progression of lung damage, highlighting the need for medium and long-term follow-up in these patients.

En las últimas décadas, el tratamiento agresivo, protocolizado y realizado en centros multidisciplinarios de fibrosis quística (FQ), ha mejorado notablemente la sobrevida media de los pacientes. Como consecuencia, síntomas más bien secundarios, como los derivados del compromiso de la vía aérea superior, entre ellos la rinosinusitis crónica (RSC), con o sin pólipos nasales (PN), han empezado a impactar en la calidad de vida y en el curso de la enfermedad. Esto hace del diagnóstico y tratamiento oportuno de esta complicación un objetivo importante en el manejo de la FQ. El propósito de esta revisión es proporcionar una actualización sobre los aspectos diagnósticos y las terapias disponibles para el manejo de la RSC en pacientes con FQ.
In recent decades, aggressive, protocolized treatment conducted in multidisciplinary cystic fibrosis (CF) centers has significantly improved the median survival of patients. Consequently, secondary symptoms, such as those arising from upper airway involvement, including chronic rhinosinusitis (CRS), with or without nasal polyps (NP), have begun to impact the quality of life and the course of the disease. This makes timely diagnosis and treatment of this complication an important goal in CF management. The purpose of this review is to provide an update on diagnostic aspects and available therapies for managing CRS in patients with CF.

@#Cystic Fibrosis (CF) is a rare condition among Asians and has not been reported in the Philippines as of this time. The inclusion of this disease in the Philippines’ Expanded Newborn Screening Program (ENBS) has provided this Filipino family the opportunity of early detection and appropriate management of this condition that could ensure the survival of the proband and his other surviving siblings. Here we present a case of a 24-month-old male who had a positive Expanded Newborn Screening (ENBS) test for cystic fibrosis and eventually underwent further tests to confirm a homozygous deletion of exons 1 - 2 of the CFTR gene. He subsequently had recurrent pneumonia but is being managed by a team consisting of a pulmonologist, gastroenterologist, and a metabolic dietitian. The proband had an older sibling whose Newborn Screening (NBS) test was normal and who eventually expired from recurrent bouts of pneumonia. This sibling was never managed as a case of cystic fibrosis. Implications on the diagnosis and management of CF in the local setting is also discussed. The importance of an appropriate CF panel customized to the local population should be reiterated and carrier testing should be encouraged to help with proper family counseling for future pregnancies for the family involved.

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.

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.

Introducción: la fibrosis quística (FQ) es una enfermedad genética, multisistémica, caracterizada por la disfunción de las glándulas de secreción exocrina secundaria a la mutación de una proteína transmembrana que actúa como canal de cloro. La inclusión de su búsqueda en el Sistema Nacional de Pesquisa Neonatal (SNPN) determinó un gran impacto sobre la morbimortalidad de esta enfermedad, permitiendo un diagnóstico y tratamiento precoz. El íleo meconial (IM) es la manifestación más precoz de la enfermedad, ocurriendo en un 10% a 18% de los pacientes. Objetivo: describir una forma de presentación precoz de FQ con resultado de pesquisa neonatal normal. Caso clínico: 18 meses. Sexo femenino; 33 semanas de edad gestacional. Retraso en la expulsión del meconio. Al tercer día de vida íleo meconial con oclusión intestinal, vólvulo de intestino medio y necrosis intestinal. Se realiza resección quirúrgica. Tripsina inmunorreactiva (TIR) normal a los 7 y 23 días de vida. No se solicita proteína asociada a la pancreatitis (PAP). Desnutrición crónica, bronquiolitis grave a los 3 meses, neumonías virales a los 7 y 11 meses. Ingreso con diagnóstico de neumonía aguda comunitaria con insuficiencia respiratoria. Test del sudor alterado en dos oportunidades. Elastasa pancreática insuficiente. Se aísla Staphylococcus aureus y Pseudomonas aeruginosa en exudado nasal y de secreciones respiratorias. Estudio genético: mutación Delta F508. Con diagnóstico de FQ se inició abordaje multidisciplinario, tratamiento y derivación al centro especializado. Conclusiones: la existencia de IM puede dar falsos negativos en el valor de la TIR, siendo necesaria la dosificación de la PAP. El pronóstico de estos pacientes va a depender de un diagnóstico precoz y el manejo terapéutico oportuno en centros especializados.
Introduction: cystic fibrosis (CF) is a genetic, multisystemic disease, characterized by dysfunction of the exocrine secretion glands secondary to the mutation of a transmembrane protein that acts as a chloride channel. Including its research by the National Neonatal Screening System (SNPN) caused a great impact on the morbidity and mortality of this disease, enabling early diagnosis and treatment. Meconium ileus (MI) is the earliest manifestation of the disease, occurring in 10% to 18% of patients. Objective: to describe a form of early presentation of CF with normal neonatal screening results. Clinical case: 18 months. Female, 33 weeks gestational age. Delay in the expulsion of meconium. On the third day of life, meconium ileus with intestinal obstruction, midgut volvulus and intestinal necrosis. Surgical resection is performed. Trypsin immunoreactive (TIR) normal at 7 and 23 days of age. Pancreatitis-associated protein (PAP) is not requested. Chronic malnutrition, severe bronchiolitis at 3 months, viral pneumonia at 7 and 11 months. Admission with a diagnosis of acute community pneumonia with respiratory failure. Sweat test altered on two occasions. Insufficient pancreatic elastase. Staphylococcus aureus and Pseudomonas aeruginosa were isolated in nasal exudate and respiratory secretions. Genetic study: Delta F508 mutation. With the CF diagnosis, a multidisciplinary approach, treatment and referral to a specialized center began. Conclusions: the existence of MI can provide false negatives in the IRR value, making PAP dosage necessary. The prognosis of these patients will depend on early diagnosis and timely therapeutic management at specialized centers.

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.

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.

Objective: To evaluate the value of nasal nitric oxide (nNO) measurement as a diagnostic tool for Chinese patients with primary ciliary dyskinesia (PCD). Methods: This study is a retrospective study. The patients were recruited from those who were admitted to the respiratory Department of Respiratory Medicine, Children's Hospital of Fudan University from March 2018 to September 2022. Children with PCD were included as the PCD group, and children with situs inversus or ambiguus, cystic fibrosis (CF), bronchiectasis, chronic suppurative lung disease and asthma were included as the PCD symptom-similar group. Children who visited the Department of Child health Care and urology in the same hospital from December 2022 to January 2023 were selected as nNO normal control group. nNO was measured during plateau exhalation against resistance in three groups. Mann-Whitney U test was used to analyze the nNO data. The receiver operating characteristic of nNO value for the diagnosis of PCD was plotted and, the area under the curve and Youden index was calculated to find the best cut-off value. Results: nNO was measured in 40 patients with PCD group, 75 PCD symptom-similar group (including 23 cases of situs inversus or ambiguus, 8 cases of CF, 26 cases of bronchiectasis or chronic suppurative lung disease, 18 cases of asthma), and 55 nNO normal controls group. The age of the three groups was respectively 9.7 (6.7,13.4), 9.3 (7.0,13.0) and 9.9 (7.3,13.0) years old. nNO values were significantly lower in children with PCD than in PCD symptom-similar group and nNO normal controls (12 (9,19) vs. 182 (121,222), 209 (165,261) nl/min, U=143.00, 2.00, both P<0.001). In the PCD symptom-similar group, situs inversus or ambiguus, CF, bronchiectasis or chronic suppurative lung disease and asthma were significantly higher than children with PCD (185 (123,218), 97 (52, 132), 154 (31, 202), 266 (202,414) vs. 12 (9,19) nl/min,U=1.00, 9.00, 133.00, 0, all P<0.001). A cut-off value of 84 nl/min could provide the best sensitivity (0.98) and specificity (0.92) with an area under the curve of 0.97 (95%CI 0.95-1.00, P<0.001). Conclusions: nNO value can draw a distinction between patients with PCD and others. A cut-off value of 84 nl/min is recommended for children with PCD.

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.

A Covid-19 é uma infecção respiratória aguda, potencialmente grave e que rapidamente se tornou uma pandemia sem precedentes na contemporaneidade, podendo ser entendida como um dos maiores desafios sanitários da humanidade neste século. A Covid-19 trouxe enormes preocupações à comunidade envolvida nos cuidados dos pacientes com fibrose cística (FC), que é uma doença rara, crônica e multissistêmica, que leva a grandes danos aos pulmões, pâncreas e outros órgãos. O tratamento da FC é composto por uma rotina diária de medicações, dieta e fisioterapia, que auxiliam na manutenção de uma boa condição pulmonar e nutricional, melhorando a expectativa e a qualidade de vida. Diante da complexidade do tratamento, ele é realizado em centros de referência e por equipe multiprofissional. A adoção do isolamento social que foi necessária para evitar a disseminação da Covid-19, interrompeu e/ou adiou os atendimentos possibilitando o agravamento dos quadros de saúde dos pacientes com FC. O objetivo desse estudo foi investigar as alterações provocadas pela pandemia da Covid-19 na rotina de cuidados das crianças e adolescentes com FC. Assim realizou-se um estudo transversal considerando as respostas a partir do levantamento online, nos meses de novembro e dezembro de 2021, com os responsáveis por crianças e adolescentes com FC que são acompanhadas no Instituto Nacional de Saúde da Mulher, da Criança e do Adolescente Fernandes Figueira (IFF). Participaram do estudo 75 responsáveis. Observou-se que as restrições impostas pela pandemia intensificaram as dificuldades já vividas pelas crianças e adolescentes com FC e trouxeram rupturas na trajetória de cuidado à saúde, medos, incertezas e profundos desgastes físicos e psicológicos. A perda de renda durante a pandemia, as dificuldades para realização de exames em geral e a falta de suplementos calóricos foram associados a piora do quadro pulmonar e/ou nutricional dos pacientes com FC, assim como alterações no sono e no humor. Diante dos resultados apresentados conclui-se que o fortalecimento de políticas públicas se faz necessário para ampliação do acesso aos benefícios sociais e redes de apoio psicológico aos pacientes com FC e suas famílias a fim garantir suporte material e afetivo no cenário pós pandêmico para a conservação do estado de saúde dos pacientes. A consulta remota foi uma ferramenta fundamental para o gerenciamento da FC durante a pandemia da Covid-19, sendo possível manter a continuidade dos cuidados mesmo com o distanciamento social, tendo grande adesão por parte dos pacientes, no entanto para se obter êxito na teleconsulta é necessário que os pacientes tenham acesso a tecnologias apropriadas e os profissionais de saúde prestem informações de fácil compreensão.

Covid-19 is an acute, potentially serious respiratory infection that has rapidly become an unprecedented pandemic in contemporary times and can be understood as one of the greatest health challenges facing humanity in this century. Covid-19 has brought enormous concern to the community involved in the care of patients with cystic fibrosis (CF), which is a rare, chronic and multisystem disease that leads to major damage to the lungs, pancreas and other organs. Treatment for CF consists of a daily routine of medication, diet and physiotherapy, which help to maintain a good pulmonary and nutritional condition, improving life expectancy and quality of life. Given the complexity of the treatment, it is carried out in reference centers and by a multi-professional team. The adoption of social isolation, which was necessary to prevent the spread of Covid-19, has interrupted and/or postponed treatment, making it possible for CF patients' health conditions to worsen. The aim of this study was to investigate the changes caused by the Covid-19 pandemic in the care routine of children and adolescents with CF. Thus, a cross-sectional study was carried out considering the responses from the online survey, in the months of November and December 2021, with the guardians of children and adolescents with CF who are monitored at the Fernandes Figueira National Institute for Women's, Children's and Adolescents' Health (IFF). Seventy-five caregivers took part in the study. It was observed that the restrictions imposed by the pandemic intensified the difficulties already experienced by children and adolescents with CF and brought disruptions to the health care path, fears, uncertainties and profound physical and psychological stress. The loss of income during the pandemic, the difficulties in carrying out tests in general and the lack of calorie supplements were associated with a worsening of the pulmonary and/or nutritional condition of CF patients, as well as changes in sleep and mood. In view of the results presented, it can be concluded that public policies need to be strengthened in order to increase access to social benefits and psychological support networks for CF patients and their families, in order to guarantee material and emotional support in the post pandemic scenario for the preservation of patients' state of health. The remote consultation was a fundamental tool for managing CF during the Covid-19 pandemic, making it possible to maintain continuity of care even with social distancing, with great adherence on the part of patients. However, in order for teleconsultation to be successful, it is necessary for patients to have access to appropriate technologies and for health professionals to provide information that is easy to understand.

Las disglicemias, objetivadas en el test de tolerancia a la glucosa de 2 horas y en el monitoreo continuo de glicemia, son el factor de riesgo principal para el desarrollo de la diabetes relacionada a fibrosis quística (FQ) (DRFQ), la que constituiría la etapa final de un continuo de alteraciones del metabolismo de la glucosa en los pacientes con FQ. Estas disglicemias se deben tanto al daño directo de las células de los islotes pancreáticos productores de insulina, como al aumento de la resistencia a la insulina asociada al estado inflamatorio sistémico de la FQ. El uso cada vez más precoz de los moduladores del CFTR debiera contribuir a evitar el desarrollo de DRFQ y sus complicaciones. La siguiente revisión se enfoca en los efectos de los moduladores del CFTR en la tolerancia a la glucosa en pacientes con FQ.
Dysglycemia, observed in the 2-hour glucose tolerance test and in the continuous monitoring of glycemia, are the main risk factor for the development of diabetes related to cystic fibrosis (CF), which constitutes the final stage of a continuum of impaired glucose metabolism in people with CF. These dysglycemias are due both to direct damage to insulin-producing pancreatic islet cells, and to increased insulin resistance associated with the systemic inflammatory state of CF. The increasingly early use of CFTR modulators should help prevent the development of CRFD and its complications. The following review focuses on the effects of regulador de transmembrana de fibrosis quística (CFTR) modulators on glucose tolerance in people with CF.

Introducción: La fibrosis quística (FQ), afecta el epitelio exocrino, formando una mucosidad espesa que obstruye los conductos de los diferentes órganos, siendo el pulmón y páncreas los más afectados. El objetivo del presente estudio fue determinar la asociación entre los factores clínicos y las complicaciones, así como la supervivencia de pacientes con FQ atendidos en un centro de referencia pediátrica en México. Métodos: El presente estudio observacional, longitudinal, fue realizado en el Instituto Nacional de Pediatría en México, de abril del 2012, a abril del 2022. Con una muestra no probabilística ingresaron al estudio niños con fibrosis quística. Las variables fueron: demográficas, complicaciones pulmonares, extrapulmonares y mortalidad. Se realiza la asociación con chi-cuadrado y la supervivencia con Kaplan-Meir. Resultados: Se analizan 71 pacientes, lactantes menores 41 casos (62%), pre-escolares 12 casos (16.9%). Fueron 40 hom-bres (56.3%). 57 casos (80.3%) tuvieron exacerbación infecciosa, 11 casos (15.5%) aspergi-losis broncopulmonar, 9 casos (12.7%) con hipertensión pulmonar, 5 casos (7%) con neumotórax, 12 casos (16.9%) con ventilación mecánica, 70 casos (98.5) con insuficiencia pancreática, 10 casos (14%) con enfermedad hepatobiliar. Hubo asociación de complica-ciones extrapulmonares con el fenotipo F508. La supervivencia global fue de 150 meses. En pacientes con ventilación mecánica invasiva la supervivencia fue de 55 meses (P<0.001), en pacientes con ventilación mecánica no invasiva fue de 106 meses (P<0.001), en pacientes con neumotórax fue de 25 meses P<0.001, en pacientes con aspergilosis bronco-pulmonar alérgica fue de 125 meses P<0.01. Conclusión: la mayor compli-cación extrapulmonar de pa-cientes con FQ es la insuficien-cia pancreática. La presencia de neumotórax disminuye la supervivencia.
Introduction: Cystic fibrosis (CF) affects the exocrine epithelium, forming a thick mucus that obstructs the ducts of the different organs, with the lungs and pancreas being the most affected. This study aimed to determine the association between clinical factors and complications, as well as the survival of CF patients treated at a pediatric reference center in Mexico. Methods: This observational, longitudinal study was conducted at the National Institute of Pediatrics in Mexico from April 2012 to April 2022. Children with cystic fibrosis were entered into the study with a nonprobabilistic sample. The variables were demographic, pulmonary and extrapulmonary complications and mortality. The association was made with chi-square and survival with Kaplan- Meir. Results: Seventy-one patients were analyzed, including 41 infants (62%) and 12 preschoolers (16.9%). There were 40 men (56.3%). Fifty-seven cases (80.3%) had an infectious exacerbation, 11 cases (15.5%) had allergic bronchopulmonary aspergillosis, 9 cases (12.7%) had pulmonary hypertension, 5 cases (7%) had pneumothorax, 12 cases (16.9%) had mechanical ventilation, 70 cases (98.5%) had pancreatic insufficiency, and 10 cases (14%) had hepatobiliary disease. There was an association of extrapulmonary complications with the F508 phenotype. Overall survival was 150 months. In patients with invasive mechanical ventilation, survival was 55 months (P<0.001); in patients with noninvasive mechanical ventilation, it was 106 months (P<0.001); in patients with pneumothorax, it was 25 months (P<0.001); and in patients with allergic bronchopulmonary aspergillosis, it was 125 months (P<0.01). Conclusion: The most significant extrapulmonary complication in CF patients is pancreatic insufficiency. The presence of pneumothorax markedly decreases survival.
