ABSTRACT

El síndrome de apneas obstructivas del sueño (SAOS) en pediatría constituye un trastorno asociado a múltiples consecuencias en el espectro cognitivo y comportamental. El principal factor de riesgo asociado es la hipertrofia amigdalina y las vegetaciones adenoideas. La adenoamigdalectomía es el tratamiento de primera línea. La incidencia del SAOS persistente varía entre un 15 % y un 75 % según las comorbilidades. Este se presenta como un desafío a la hora de tratarlo; requiere un abordaje integral para su diagnóstico y tratamiento adecuado. El objetivo de esta revisión bibliográfica es proponer un abordaje diagnóstico y terapéutico para el SAOS persistente.


In pediatrics, obstructive sleep apnea syndrome (OSAS) is a disorder associated with multiple consequences at the cognitive and behavioral level. The main associated risk factor is the presence of tonsillar hypertrophy and adenoids. An adenotonsillectomy is the first-line treatment. The incidence of persistent OSAS varies from 15% to 75%, depending on comorbidities. This is a challenge in terms of management; it requires a comprehensive approach for an adequate diagnosis and treatment. The objective of this bibliographic review is to propose a diagnostic and therapeutic approach for persistent OSAS.

ABSTRACT

Abstract Objective To measure the average time for the diagnosis and for the therapeutic prescription of Continuous Positive Airway Pressure (CPAP) at a hospital in Botucatu Medical School - State University São Paulo, UNESP. Method A retrospective observational study was carried out by collecting data from the electronic medical records of patients over 18-years of age, who had a diagnostic polysomnography testing scheduled between January and December 2017. Result Of the 347 patients eligible for the study, 94 (27.1%) missed follow-up and 103 (29.7%) had a referral for CPAP use. Until February 2021, only 37 (35.9%) of these patients had already acquired and were using the device, the remaining 66 (64.1%) were waiting or gave up the therapy. The mean value of the waiting time interval between the referral of the diagnostic test and its performance was equivalent to 197 days (6.5 months). The mean time between diagnostic polysomnography and CPAP prescription was 440-days (14.5-months), with a total mean time of 624 days (21-months). Conclusion As in other services, the diagnostic-therapeutic flow proved to be highly inefficient, with a long waiting period, difficult access to treatment and a high dropout rate. These findings highlight the need to establish new patient-centered strategies with measures that speed up the flow and facilitate access to CPAP, in order to reduce the morbidity and mortality associated with this condition. Level of evidence Level 3 - Non-randomized controlled cohort/follow-up study Recommendation B.

ABSTRACT

Abstract Objective Summarize the evidence on drug therapies for obstructive sleep apnea. Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. PubMed, Embase, Scopus, Web of Science, SciELO, LILACS, Scopus, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched on February 17th, 2023. A search strategy retrieved randomized clinical trials comparing the Apnea-Hypopnea Index (AHI) in pharmacotherapies. Studies were selected and data was extracted by two authors independently. The risk of bias was assessed using the Cochrane Risk of Bias tool. RevMan 5.4. was used for data synthesis. Results 4930 articles were obtained, 68 met inclusion criteria, and 29 studies (involving 11 drugs) were combined in a meta-analysis. Atomoxetine plus oxybutynin vs placebo in AHI mean difference of -7.71 (-10.59, -4.83) [Fixed, 95 % CI, I2 = 50 %, overall effect: Z = 5.25, p < 0.001]. Donepezil vs placebo in AHI mean difference of -8.56 (-15.78, -1.33) [Fixed, 95 % CI, I2 = 21 %, overall effect: Z = 2.32, p = 0.02]. Sodium oxybate vs placebo in AHI mean difference of -5.50 (-9.28, -1.73) [Fixed, 95 % CI, I2 = 32 %, overall effect: Z = 2.86, p = 0.004]. Trazodone vs placebo in AHI mean difference of -12.75 (-21.30, -4.19) [Fixed, 95 % CI, I2 = 0 %, overall effect: Z = 2.92, p = 0.003]. Conclusion The combination of noradrenergic and antimuscarinic drugs shows promising results. Identifying endotypes may be the key to future drug therapies for obstructive sleep apnea. Moreover, studies with longer follow-up assessing the safety and sustained effects of these treatments are needed. PROSPERO registration number CRD42022362639.

ABSTRACT

ABSTRACT BACKGROUND: The cardiopulmonary function of patients with obstructive sleep apnea (OSA) is significantly lower than that of patients with simple snoring and is significantly related to the severity of OSA. Currently, only a few studies have been conducted on cardiopulmonary exercise testing in overweight patients with OSA. OBJECTIVE: To analyze the correlation between cardiopulmonary exercise test (CPET) indices and the condition of overweight patients with OSA. DESIGN AND SETTING: Retrospective study in Guangdong Provincial Hospital of Chinese Medicine. METHODS: This study included 73 hospitalized overweight patients. The patients were divided into no, mild, moderate, and severe OSA groups. Differences in the CPET indices among the four groups were compared. The correlation between the CPET indices and conditions was analyzed. RESULTS: No, mild, moderate, and severe OSA groups had 18 men and 5 women, 11 men and 3 women, 12 men and 2 women, and 21 men and 1 woman, respectively (P > 0.05). No significant difference was observed in resting pulmonary function among the four groups (P > 0.05). In the CPET, the anaerobic threshold, maximum oxygen uptake, and oxygen pulse were significantly lower in the severe OSA group than those in the normal OSA group (P < 0.05). Moreover, CPET indices negatively correlated with the apnea-hypopnea index. CONCLUSION: Changes in CPET indices occurred earlier than changes in resting pulmonary function in patients with OSA. CPET might be a potential method for evaluating the severity of OSA combined with overweight status.

ABSTRACT

ABSTRACT Objective: This study aimed to evaluate whether the therapeutic use of caffeine for premature newborns is associated with changes in sleep habits and the presence of obstructive sleep apnea in childhood. Methods: This is a cross-sectional single-center study in which the caretakers of 87 children aged 5-10 years, born full-term or preterm, treated or not with caffeine in the neonatal period, answered questionnaires to screen for obstructive sleep apnea (Pediatric Obstructive Sleep Apnea Screening Tool [PosaST]) and to characterize the sleep habits (Children's Sleep Habits Questionnaire [CSHQ]) of their children. ANOVA and linear regression tests were performed to verify possible differences between the groups. Results: Children born prematurely who were treated with caffeine woke up significantly later on weekdays than those born at term (09h±00h58 and 07h43±1h15, respectively, p=0.022) and had longer total daily sleep time also compared to those born at term (10h24±1h08 and 09h29±1h08, respectively, p<0.001). There was no significant difference between the three groups in overall PosaST and CSHQ scores. Conclusions: Caffeine use in the neonatal period did not impair sleep habits later in life and did not lead to increased obstructive sleep apnea scores in prematurely born children compared to those born at term.


RESUMO Objetivo: Avaliar se o uso terapêutico de cafeína para recém-nascidos prematuros se associa a alterações nos hábitos de sono e à presença de apneia obstrutiva do sono na infância. Métodos: Este é um estudo unicêntrico transversal no qual os responsáveis por 87 crianças com idades entre cinco e dez anos, nascidas a termo ou pré-termo e tratadas ou não com cafeína no período neonatal responderam a questionários para triagem de apneia obstrutiva do sono (Pediatric Obstructive Sleep Apnea Screening Tool - PosaST) e para a caracterização dos hábitos de sono (Children's Sleep Habits Questionnaire - CSHQ) de seus filhos. Foram realizados testes de variância (ANOVA) e de regressão linear para verificar possíveis diferenças entre os grupos. Resultados: As crianças nascidas prematuras que foram tratadas com cafeína acordaram significativamente mais tarde nos dias de semana do que as nascidas a termo (09h±00h58 e 07h43±1h15, respectivamente, p=0,022) e tiveram maior tempo total de sono diário também comparadas às nascidas a termo (10h24±1h08 e 09h29±1h08, respectivamente, p<0,001). Não houve diferença significativa entre os três grupos na pontuação geral dos questionários PosaST e CSHQ. Conclusões: O uso de cafeína no período neonatal não prejudicou tardiamente os hábitos de sono e não levou ao aumento dos escores de apneia obstrutiva do sono de crianças nascidas prematuras quando comparadas com crianças nascidas a termo.

ABSTRACT

RESUMO Objetivo Identificar e correlacionar as queixas de alterações miofuncionais orofaciais e de risco para distúrbios respiratórios do sono com hábitos de sono na infância. Método Participaram 71 pais ou responsáveis de crianças de 6 a 11 anos, matriculadas em uma escola pública. Foi aplicado um formulário com questões semiestruturadas/anamnese e os protocolos Nordic Orofacial Test-Screening - entrevista, Pediatric Obstructive Sleep Apnea Screening Tool Questionnaire, e Children's Sleep Habits Questionnaire - todos em suas versões em português/Brasil no formato online. Para a análise estatística, realizou-se o teste de correlação de Spearman, considerando o nível de significância de 5%. Resultados 29 crianças eram do sexo feminino (40,8%) e 42 do sexo masculino (59,2%), com média de idade de 8,52 anos. As queixas miofuncionais orofaciais encontradas foram relacionadas às funções de respiração (35,2%), mastigação e deglutição (32,4%) e hábitos deletérios (33,8%). Todas as crianças apresentaram um baixo risco para distúrbios respiratórios do sono e quanto aos hábitos de sono, 23 crianças (32,39%) apresentaram uma somatória menor, enquanto que 48 crianças (67,61%) ultrapassaram 41 pontos. Conclusão Houve correlação entre risco para distúrbios respiratórios do sono em crianças com as queixas de alterações miofuncionais orofaciais e com a baixa qualidade/maus hábitos de sono.


ABSTRACT Purpose To identify orofacial myofunctional complaints and sleep-disordered breathing and correlate them with sleep habits in childhood. Methods The study included 71 parents/guardians of public school children aged 6 to 11 years. They answered a form with semi-structured medical history questions and the Nordic Orofacial Test-Screening - interview, the Pediatric Obstructive Sleep Apnea Screening Tool Questionnaire, and the Children's Sleep Habits Questionnaire - all of them in their Portuguese/Brazilian versions in an online format. Statistical analyses used Spearman's correlation, setting the significance level at 5%. Results There were 29 female children (40.8%) and 42 male ones (59.2%), with a mean age of 8.52 years. The study found orofacial myofunctional complaints related to breathing functions (35.2%), chewing and swallowing (32.4%), and deleterious habits (33.8%). All children were at a low risk of sleep-disordered breathing. As for sleep habits, 23 children (32.39%) had a lower total score, whereas 48 children (67.61%) exceeded 41 points. Conclusion There was a correlation between the risk of sleep-disordered breathing in children with complaints of orofacial myofunctional disorders and poor sleep quality/habits.

ABSTRACT

ABSTRACT BACKGROUND: Neck circumference (NC) is a useful anthropometric measure for predicting obstructive sleep apnea (OSA). Ethnicity and sex also influence obesity phenotypes. NC cut-offs for defining OSA have not been established for the Latin American population. OBJECTIVES: To evaluate NC, waist circumference (WC), and body mass index (BMI) as predictors of OSA in the Colombian population and to determine optimal cut-off points. DESIGN AND SETTING: Diagnostic tests were conducted at the Javeriana University, Bogota. METHODS: Adults from three cities in Colombia were included. NC, WC, and BMI were measured, and a polysomnogram provided the reference standard. The discrimination capacity and best cut-off points for diagnosing OSA were calculated. RESULTS: 964 patients were included (57.7% men; median age, 58 years) and 43.4% had OSA. The discrimination capacity of NC was similar for men and women (area under curve, AUC 0.63 versus 0.66, P = 0.39) but better for women under 60 years old (AUC 0.69 versus 0.57, P < 0.05). WC had better discrimination capacity for women (AUC 0.69 versus 0.57, P < 0.001). There were no significant differences in BMI. Optimal NC cut-off points were 36.5 cm for women (sensitivity [S]: 71.7%, specificity [E]: 55.3%) and 41 cm for men (S: 56%, E: 62%); and for WC, 97 cm for women (S: 65%, E: 69%) and 99 cm for men (S: 53%, E: 58%). CONCLUSIONS: NC and WC have moderate discrimination capacities for diagnosing OSA. The cut-off values suggest differences between Latin- and North American as well as Asian populations.

ABSTRACT

Contexte et objectifs : L'accès aux tests neurophysiologiques pour le diagnostic des Troubles du Sommeil (TS) est très limité dans les pays d'Afrique subsaharienne. La présente étude avait pour objectif de déterminer les caractéristiques épidémiologiques, cliniques et neurophysiologiques des (TS) dans un groupe de jeunes adultes. Méthodes : Il s'est agi d'une étude descriptive d'une série de cas, réalisée au centre de Médecine du sommeil et des maladies respiratoires de l'hôpital de la Croix-Rousse de Lyon du 1er janvier au 31 mars 2019. Les patients hospitalisés pendant cette période pour l'exploration d'un (TS) ont été sélectionnés. Etaient éligibles ceux dont l'âge était compris entre 18 et 35 ans, des deux sexes, ayant renseigné un questionnaire et ayant bénéficié au minimum d'une polysomnographie (PSG). Résultats : Quatre-vingt-onze patients étaient examinés. Les femmes étaient les plus affectées (59,3 %). Leur âge moyen était de 26,6 ± 5 ans. La PSG a incriminé le Syndrome d'Apnée Hypopnée Obstructive du sommeil (SAHOS) comme étiologie principale (66 %). Pour les patients sans SAHOS, 38,7 % avaient une PSG normale et la PSG avec d'autres tests de sommeil ont objectivé, pour le reste (61,3 %), d'autres types de (TS). La dépression (50,7 %) et la fatigue chronique (84,6 %) étaient très fréquentes. L'indice d'efficacité du sommeil était faible pour 70 % des patients avec SAHOS. Il y avait un déséquilibre de la durée des stades du sommeil, augmentée pour le sommeil lent léger et diminuée pour le sommeil lent profond dans la population avec SAHOS, tandis que la durée du sommeil paradoxal chez ceux sans SAHOS était augmentée. Conclusion Le SAHOS est fréquent dans cette formation hospitalière, avec des répercussions significatives à type de dépression et de fatigue chronique. Il est important que des mesures rendant accessible l'usage des tests d'exploration du sommeil particulièrement en Afrique au sud du Sahara, soient mises en place pour diagnostiquer ces troubles


Context and objective. Access to neurophysiological tests for diagnostic of sleep disorders (SD) is very limited in Sub-Saharan Africa countries. The objective was to determine the epidemiological, clinical and neurophysiological characteristics of SD in a young adult group. Methods. This was a descriptive serial cases study carried out at the Sleep Medicine and Respiratory Diseases Center of the CroixRousse hospital of Lyon between January 1st and March 31th, 2019. Patients hospitalized during this period with tests for SD were selected. Eligible were those aged between 18 and 35 years, both sexes, who completed a questionnaire and who received at least a polysomnography (PSG). Results. Ninety-one patients were involved. Women remained the most affected (59.3%). Mean age was 26.6±5 years. PSG incriminated obstructive sleep apnea (OSA) syndrome as the primary etiology (66%). For patients without OSA, 38.7% had normal PSG. For the remaining 61.3% of patients, other types of SD were found using PSG with various sleep tests. Depression (50.7%) was an important comorbidity, and chronic fatigue (84.6%) was the most frequent complaint. Sleep efficiency index was low for 70% of sleep apnea patients. There was an imbalance in the duration of sleep stages, with an increase in light slow-wave sleep in the OSA population and a decrease in their deep slow-wave sleep, while REM sleep duration in patients without OSA was increased. Conclusion: OSA was the primary etiology in our study, with significant repercussions like depression and chronic fatigue. Public health measures such as increasing access to the use of sleep exploration tests, especially in subSaharan Africa, should be put in place for the diagnosis of these sleep disorders and their consequences

ABSTRACT

Resumo Objetivos Identificar os instrumentos de avaliação de equilíbrio, quedas e risco de quedas utilizados na DPOC, avaliar suas propriedades de medida, qualidade da evidência e utilidade clínica. Método A revisão foi produzida seguindo as orientações PRISMA e COSMIN, registrada no PROSPERO: CRD42021235118. As pesquisas foram realizadas de novembro de 2021 a setembro de 2022 nas bases de dados PubMed, LILACS, CINAHL, Embase, Web of Science e PEDro. Estudos observacionais transversais e coorte foram incluídos, sem restrição de idioma ou ano de publicação, desde que descreveram instrumentos clínicos de avaliação do equilíbrio, quedas e risco de quedas reportando no mínimo, uma das propriedades de medida: validade, confiabilidade e responsividade. Dois revisores independentemente aplicaram os critérios de elegibilidade, risco de viés pela COSMIN, qualidade da evidência pela abordagem GRADE e a avaliação da utilidade clínica pela Escala de Tyson e Connell. Resultados 9.102 estudos foram selecionados e 21 incluídos na revisão, nove estudos demonstraram propriedades de medida adequadas e suficientes e 12 instrumentos foram identificados, dos quais seis, foram avaliados quanto a qualidade de evidência. Conclusão Revisões sistemáticas de propriedades de medida requerem revisores especializados e habilidade em análise qualitativa. Com grau de recomendação "A", a Berg Balance Scale (BBS) e o teste Timed Up and Go (TUG) foram os instrumentos mais indicados na DPOC. Ao acrescentar a avaliação da utilidade clínica ao resultado, o TUG demonstra superioridade ao BBS, demostrando ser uma ótima ferramenta para triar indivíduos que necessitem de uma avaliação minuciosa do equilíbrio, quedas e risco de quedas.


Abstract Objectives to identify balance assessment instruments, issues and risks of issues used in COPD, evaluate their measurement properties, quality of evidence and clinical utility. Method A review was produced following the PRISMA and COSMIN guidelines, registered in PROSPERO: CRD42021235118. Searches were carried out from November 2021 to September 2022 in the PubMed, LILACS, CINAHL, Embase, Web of Science and PEDro databases. Cross-sectional and cohort observational studies were included, without restrictions on language or year of publication, as long as they described clinical instruments for assessing balance, falls and risk of falls reporting at least one of the measurement properties: validity, reliability and responsiveness. Two reviewers will independently apply the eligibility criteria, travel risk by COSMIN, quality of evidence by the GRADE approach and assessment of clinical utility by the Tyson and Connell Scale. Results 9,102 studies were selected and 21 included in the review, nine studies demonstrated adequate and sufficient measurement properties and 12 instruments were identified, of which six were evaluated for the quality of evidence. Conclusion Systematic reviews of measurement properties require specialized reviewers and skills in qualitative analysis. With a recommendation GRADE of "A", the Berg Balance Scale (BBS) and the Timed Up and Go (TUG) test were the most recommended instruments for COPD. By requiring the evaluation of the clinical utility of the result, the TUG demonstrates superiority to the BBS, proving to be a great tool for judging individuals who need a thorough assessment of balance, falls and risk of falls.

ABSTRACT

Objective To analyze the clinical characteristics and influencing factors of non-small cell lung cancer (NSCLC) patients with chronic obstructive pulmonary disease (COPD) in Hubei province, and to provide a theoretical basis for the diagnosis and treatment of NSCLC patients with COPD. Methods A total of 246 NSCLC patients admitted to our hospital from 2018 to 2020 were selected and divided into control group (without COPD, n=125) and observation group (with COPD, n=121) according to COPD. The clinical characteristics of chest pain, hemoptysis, emasculation, atelectasis and pleural effusion were compared between the two groups. The values of FEV1/FVC, RV/TLC and DLCO in the two groups were measured by pulmonary function detector. The age, gender, smoking, smoking history, proportion of lung squamous cell carcinoma, TNM stage and other clinical data of all subjects were analyzed by self-made survey scale of our hospital. Univariate analysis and logistic regression were used to analyze the risk factors of COPD in NSCLC patients. Results Among 246 NSCLC patients, 121 patients (49.19%) were complicated with COPD, including 76 males and 45 females, and there was a statistical difference between the two groups (χ2=4.891, P>0.05). The average age of the observation group (61.02±4.82) was significantly higher than that of the control group (59.76±4.73) (t=2.069, P0.05). Male (OR=2.982), smoking history (OR=2.623) and lung squamous cell carcinoma (OR=3.147) were risk factors for COPD in NSCLC patients (P<0.05). Conclusions NSCLC patients with COPD are more common in male smokers in Hubei Province, often accompanied by pleural effusion , severe hemoptysis and other symptoms , and their lung function is decreased. Early detection and standardized treatment of COPD in the treatment of NSCLC can improve the prognosis of patients.

ABSTRACT

Objective To investigate the difference of the disease progression in patients with chronic obstructive pulmonary disease (COPD) with different muscle mass levels and the influence of related factors on the disease progression. Methods A total of 308 newly diagnosed patients with COPD from February 2021 to February 2022 were selected for this study. All patients were below moderate COPD. The patients were divided into two groups according to their muscle mass levels: sarcopenia group (98 cases) and control group (210 cases). The diagnostic criteria for sarcopenia were based on sarcopenia diagnostic thresholds: RSMI 2 in men and 2 for women. All subjects were followed up for 4 months to observe the progress of the patient's condition. The correlation between the muscle mass level and pulmonary function level, as well as the results of 6-minute walking test and CAT score was evaluated, and the influence of muscle mass level on the patient's disease progress was analyzed. At the same time, the potential influence of related factors (body fat rate, vitamin D level, etc.) on the condition of patients with different muscle mass levels was discussed. SPSS 19.0 software was used to perform statistical analysis. Results Under the same treatment intervention, the baseline and follow-up lung function improvement levels of patients in the sarcopenia group were lower than those in the control group, and the difference was statistically significant (P<0.05). At the same time, the baseline and follow-up 6-minute walk test results of the patients in the sarcopenia group were also worse than those of the control group, and the difference was statistically significant (P<0.05). Further correlation analysis was carried out between the patient's muscle mass level and the post-treatment pulmonary function indicators and 6MWD test level. The results showed that the muscle mass level was positively correlated with several pulmonary function indicators (FEV1, FEV1% predict) and 6MWD (both P<0.05). Considering the possible influence of other factors on the control and progress of the patient's condition, the present study used follow-up CAT score results to distinguish the prognosis of the patient's condition improvement, and used improvement and non-improvement as dependent variables to analyze the influence of various potential influencing factors. The results of regression model analysis showed that lower baseline muscle mass, women, lower body fat percentage, and lower vitamin D level were the main risk factors. Conclusion Under the same treatment condition, COPD patients with different muscle mass levels improve more slowly when complicated with sarcopenia and have poor prognosis. Women, lower body fat percentage and lower vitamin D level are potential risk factors for poor prognosis.

ABSTRACT

Chronic obstructive pulmonary disease (COPD) is one of the most common chronic diseases of the respiratory system in the clinic. The disease has a long course and is difficult to cure, which seriously threatens human health. Airway mucus hypersecretion (AMH) is an independent risk factor for COPD and has a significant impact on the development and prognosis of the disease. The review finds that the abnormal proliferation of goblet cells and the excessive secretion of mucin are the direct causes of AMH. The pathogenesis of AMH may be closely related to the inhalation of heterogeneous particles, airway inflammation, the imbalance of mucin/water salt ratio, and the regulation of related signaling pathways. Traditional Chinese medicine (TCM) believes that AMH of COPD belongs to the category of lung distension with phlegm-fluid retention syndrome, and the disease is mainly treated from phlegm on the basis of lung distension. This article summarizes the relevant research in the field of TCM in recent years and finds that the single TCM that effectively intervened AMH of COPD is mainly phlegm-resolving TCM, and the main active ingredients of TCM are flavonoids, terpenoids, phenols, and alkaloids. The main TCM compounds are mainly designed to remove heat-phlegm, warmly resolve cold-phlegm, dry dampness to eliminate phlegm, invigorate Qi, promote blood circulation and dispel phlegm, and invigorate lung, spleen, and kidney. Its mechanism of action may be direct inhibition or indirect inhibition of airway epithelial goblet cell metaplasia and mucin expression by inhibiting airway inflammation, regulating aquaporins to correct the imbalance of mucin/water salt ratio, and regulating signaling pathways, so as to reduce mucus oversecretion in COPD. However, there are still some problems. For example, the research mainly focuses on TCM compounds instead of the single TCM or its effective components. The research on the mechanism of action is not thorough enough, and the research results are not interoperable. The clinical transformation rate of basic research is insufficient. This article systematically reviews the research status of AMH in the treatment of COPD with TCM and puts forward some thoughts on the existing problems, so as to provide a reference for clinical rational medication and in-depth research.

ABSTRACT

ObjectiveTo observe the effect of Qingfei Huatan Zhuyu decoction on the lung and intestinal function of rats with chronic obstructive pulmonary diseases (COPD) and explore the deep-seated mechanism of its embodiment of lung and intestinal co-treatment. MethodA total of 60 Wistar rats were randomly divided into six groups, with 10 rats in each group, and the groups were control group, model group, acute syrup group (10 g·kg-1·d-1), and low, medium, and high-dose groups (10, 15, 20 g·kg-1·d-1) of Qingfei Huatan Zhuyu decoction. The COPD rat model was established by lipopolysaccharide tracheal drip combined with the smoke inhalation method, and the acute syrup group and the Qingfei Huatan Zhuyu decoction group were administered by gavage with corresponding dose concentrations respectively, while the rest groups were controlled by saline gavage, and the lung function and blood gas indexes of rats were monitored after the last administration. The histopathological changes in the lung and intestine were observed microscopically. The expression of serum interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and secretory immunoglobulin A (IgA) in colon tissue were measured by enzyme-linked immunosorbent assay (ELISA). The biochemical indexes such as serum diamine oxidase (DAO), D-lactic acid, and malondialdehyde (MDA) were measured. Immunohistochemistry was used to detect the expression of tight junction protein (Occludin) in rat colon tissue. The expression of F4/80 positive alveolar macrophages in rat lung tissue, and the expression of α-actin (α-SMA) and colonic atresia small band protein-1 (ZO-1) were determined by immunofluorescence. The protein expression of p-NF-κB p65, NF-κB p65, p-p38 MAPK, and p-p38 MAPK and the expression of Occludin and ZO-1 in colon tissue were detected in rat lung tissue by Western blot. ResultCompared with the normal group, the model group had pulmonary dysfunction, reduced forced vital capacity (FVC), arterial partial oxygen pressure (PaO2), arterial oxygen saturation (SaO2), and dynamic lung compliance (Cdyn) (P<0.01), and the pathological changes in the lung and intestine were obvious. The expressions of IL-6, TNF-α, DAO, D-lactic acid, and MDA in serum were increased (P<0.05,P<0.01), and the protein expression ratio of p-NF-κB p65/NF-κB p65 and p-p38 MAPK/p38 MAPK in lung tissue was increased. The expression of F4/80 positive macrophages in lung tissue was enhanced. The expression of IgA, Occludin, and ZO-1 in colon tissue decreased (P<0.05,P<0.01). Compared with the model group, the pulmonary function of the rats in the acute syrup group and groups of Qingfei Huatan Zhuyu decoction was significantly improved, and the FVC, PaO2, SaO2, and Cdyn were increased (P<0.05, P<0.01). The pathological changes in the lung and intestine were significant. The expressions of IL-6, TNF-α, DAO, D-lactic acid, and MDA in serum were decreased (P<0.05,P<0.01), and the expressions of F4/80 positive macrophages in lung tissue were decreased (P<0.01). The protein expression ratio of p-NF-κB p65/NF-κB p65 and p-p38 MAPK/p38 MAPK in lung tissue decreased (P<0.01), and the expression of IgA, Occludin, and ZO-1 in colon tissue increased (P<0.01). ConclusionQingfei Huatan Zhuyu decoction can effectively reduce the symptoms of COPD rats, and its mechanism of action is related to inhibiting the inflammatory response of lung tissue and improving the barrier function of the intestinal mucosa.

ABSTRACT

Chronic obstructive pulmonary disease (COPD) is a common disease in clinical practice. It is associated with obvious exposure to toxic particles or gases and has become the leading cause of death and disability worldwide. The pathogenesis of COPD is complex, and the oxidative stress involved in COPD plays a crucial role in the pathological process of the disease. Patients with COPD usually have high levels of oxidative stress in the lungs, which will affect the whole body for a long time, causing a variety of complications and accelerating the development of the disease. On the one hand, oxidative stress can directly damage the airway and lung tissue. On the other hand, it also drives other pathological mechanisms to jointly promote the development of disease, such as participating in inflammatory reactions and protease/anti-protease imbalance, promoting mucus secretion, accelerating cellular senescence, causing autoimmunity, and involving in genetic regulatory pathways. At present, western medicine treatment is mostly based on conventional drug treatment, and antioxidant-targeted oxidative stress is adopted, but there are still some challenges in efficacy and safety. Traditional Chinese medicine has a long history of preventing and treating COPD. In particular, Chinese herbal medicine formulas have great potential to interfere with the oxidative stress of COPD. Whether it is the modified classical traditional Chinese medicine or the new formulation developed by modern doctors, the research results reflect the multi-target and multi-channel advantages of traditional Chinese medicine treatment, and their efficacy and safety are gradually verified. This paper reviewed the literature in recent years, starting with the basic and clinical research on the intervention of traditional Chinese herbal medicine formulas on oxidative stress of COPD, so as to provide further ideas for related research on the prevention and treatment of oxidative stress of COPD by traditional Chinese medicine.

ABSTRACT

Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung condition characterized by persistent and often progressive airflow obstruction, including airway abnormalities (e.g., bronchitis and bronchiolitis) and chronic respiratory symptoms (e.g., dyspnea, cough, and expectoration). It is one of the leading causes of death worldwide. According to the theory of traditional Chinese medicine (TCM), the lung and large intestine are interior-exterior related. Therefore, COPD can be treated from both the lung and intestine by the methods of tonifying and invigorating lung, spleen, and kidney, dispelling phlegm, and expelling stasis. Gut microbiota plays a key role in human immunity, nerve, and metabolism and may act on COPD by affecting the structures and functions of lung and intestine tissue and regulating lung inflammation and immunity. TCM can restore the balance of gut microbiota, which is conducive to the recovery from COPD. For example, the treatment method of tonifying lung and invigorating kidney can regulate gut microbiota, alleviate pulmonary and intestinal injuries, and improve lung immunity. The treatment methods of dispelling phlegm and expelling stasis can regulate gut microbiota and reduce pulmonary inflammation. According to the TCM theory of lung and large intestine being interior-exterior related, this review elaborates on the connotation of TCM in the treatment of COPD by regulating gut microbiota, aiming to provide new ideas for the clinical treatment of COPD via gut microbiota.

ABSTRACT

ObjectiveTo explore the effect of Tanreqing injection combined with Ceftazide on the clinical efficacy, lung function, and laboratory inflammatory index of patients suffering from phlegm heat obstructing lung syndrome in acute exacerbation of chronic obstructive pulmonary disease (AECOPD). MethodFrom June 2021 to June 2023, 76 patients diagnosed with phlegm heat obstructing lung syndrome in AECOPD were enrolled in the respiratory and critical medical department of Jieshou Hospital of Traditional Chinese Medicine. They were randomly divided into a control group and an observation group with 38 cases each. The control group used Ceftazidime intravenous drip and other conventional oxygen inhalation and antispasmodic treatment measures of western medicine. The observation group received Tanreqing injection intravenous drip based on the treatment of the control group, with a course of 10 days. The changes of laboratory indicators such as hs-CRP, calcitonin (PCT), and interleukin-6 (IL-6) before and after treatment were analyzed, and the improvement of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), one second rate (FEV1/FVC), assessment and improvement of the British Medical Research Society’s dyspnea index (mMRC), self-evaluation test of chronic obstructive pulmonary disease patients (CAT), and traditional Chinese medicine syndrome score was compared. In addition, the total effective rate between the two groups after treatment was compared. ResultAfter treatment, the hs-CRP, PCT, IL-6, FEV1, FVC, FEV1/FVC, mMRC, CAT scores, and traditional Chinese medicine syndrome evaluation of both groups improved (P<0.01). After treatment, compared with the control group, the observation group showed more significant improvements in hs-CRP, PCT, IL-6, FEV1, FVC, FEV1/FVC, mMRC, CAT scores, and traditional Chinese medicine syndrome evaluation, and the difference was statistically significant (P<0.05,P<0.01). The total clinical effective rate of the control group was 86.84% (33/38), while that of the observation group was 94.74% (36/38). The therapeutic effect of the observation group was better than that of the control group (χ2=8.471, P<0.05). ConclusionTanreqing injection combined with Ceftazidime has obvious efficacy in the treatment of phlegm heat obstructing lung syndrome in AECOPD, which is better than the treatment of Ceftazidime antibiotics alone. It can reduce the risk of acute exacerbation, alleviate clinical symptoms, and delay the decline of lung function.

ABSTRACT

Introducción: La epilepsia es un desorden caracterizado por la predisposición a generar crisis epilépticas, mientras que el síndrome de apnea del sueño (SAOS) ha sido reconocido como un desorden crónico de colapso intermitente de la vía aérea que genera hipoxia recurrente. En este trabajo se aplicó la escala de trastornos del sueño (Sleep Apnea Scale of the Sleep Disorders Questionnaire SA-SDQ), previamente validada en inglés para pacientes con epilepsia, a fin de determinar su capacidad para detectar apnea de sueño en nuestra población. Materiales y métodos: En una primera etapa se realizó la adaptación transcultural de la escala SA-SDQ en castellano, provista por los autores, al español colombiano. Luego se recopiló la información de los pacientes en quienes se realizó polisomnografía entre mayo y agosto del 2022 y se determinó el valor de corte para diagnosticar SAOS con la escala SA-SDQ. Resultados: Cuarenta pacientes pudieron realizarse la polisomnografía, de los cuales 30 (75 %) tuvieron índices de apnea-hipopnea superiores a 5, lo que indica SAOS. El área bajo la curva fue 0,790 y la puntuación SA-SDQ de 21 proporcionó una sensibilidad del 73,3 % (IC 53,83-87,02 %) y una especificidad del 80 % (IC 44,2-96,5 %). La consistencia interna fue aceptable (α = 0,713). Conclusiones: La escala SA-SDQ es un instrumento útil para tamizar SAOS en la población colombiana que padece epilepsia. Nuestros resultados indican que los puntos de corte sugeridos anteriormente (2936 para hombres y 26-32 para mujeres) pueden ser demasiado altos para nuestra población. Sugerimos un punto de corte de 21 para ambos.


Introduction: Epilepsy is a disorder characterized by a predisposition to have epileptic seizures, while sleep apnea syndrome (OSAS) has been recognized as a chronic disorder of intermittent collapse of the airway that generates recurrent hypoxia. In this work, the sleep disorders scale (SA-SDQ) previously validated in English for patients with epilepsy was applied to determine its ability to detect sleep apnea in our population. Materials and methods: In the first stage, the cross-cultural adaptation of the SA-SDQ scale in Spanish provided by the authors was carried out into Colombian Spanish. then the information of the patients in whom polysomnography was performed between May and August 2022 was collected and the cut-off value was determined to diagnose OSAS with the SA-SDQ scale. Results: 40 patients were able to undergo polysomnography, of which 30 (75 %) had apnea-hypopnea indices greater than five, indicating OSAS. The area under the curve was 0.790 and the SA-SDQ score of 21 provided a sensitivity of 73.3 % (CI 53.83-87.02 %) and a specificity of 80 % (CI 44.2-96, 5 %). The internal consistency was acceptable (α = 0.713). Conclusions: The SA-SDQ scale is a useful instrument for screening OSAS in the Colombian population suffering from epilepsy. Our results indicate that the previously suggested cut-off points (29-36 for men and 26-32 for women) may be too high in our population. We suggest a cutoff of 21 for both.

ABSTRACT

Introducción: En Colombia son escasos los datos sobre el uso de los inhaladores en pacientes con EPOC. Objetivo: Describir la técnica de uso de inhaladores de dosis medida y polvo seco en pacientes de un hospital colombiano. Materiales y métodos: Estudio descriptivo en pacientes mayores de 40 años con EPOC atendidos en un hospital en La Virginia, Risaralda, Colombia, entre el 1 de septiembre de 2019 al 31 de enero de 2020. La unidad de análisis fueron los pacientes. Se incluyeron variables sociodemográficas, clínicas y lista de chequeo para uso de inhaladores. Se aplicaron frecuencias y proporciones para variables discretas, estadísticas de tendencia central y dispersión para variables continuas. Resultados: Se incluyeron 104 pacientes con edad media de 73,6 ± 10,1 años; 57 eran mujeres (54,8 %). Además, 48 pacientes estaban clasificados como GOLD-D (46,2 %). Igualmente, 89 pacientes manifestaron haber recibido educación sobre el uso de broncodilatadores (85,6 %). Los más frecuentes fueron los inhaladores de dosis medida (DM) en 95 casos (91,3 %), seguido de los de polvo seco unidosis (7,7 %). Así mismo, 37 pacientes que usaron DM sin inhalocámara (35,6 %) no cumplieron los pasos de la lista de chequeo. En el sistema multidosis, el más realizado fue cerrar de manera adecuada el inhalador y el menos ejecutado, expulsar el aire lentamente evitando hacerlo cerca del inhalador (n = 6; 5,7 %). Discusión: Se lograron describir las características de la técnica de uso de los inhaladores en pacientes con EPOC. A pesar de que ningún paciente logró utilizar el inhalador de forma "perfecta", la mayoría han recibido educación por parte de los profesionales de la salud. Conclusión: Un alto porcentaje de pacientes usa inadecuadamente los dispositivos para suministrar los broncodilatadores. Esto puede impactar negativamente en el control de la enfermedad.


Introduction: In Colombia, there is limited data on the use of inhalers in patients with COPD. Objective: The objective was to describe the technique of using metered-dose inhalers and dry powder in patients in a Colombian hospital. Methods: Observational, descriptive study of patients over 40 years of age with COPD, treated in a hospital in La Virginia, Risaralda, Colombia, between September 1st, 2019 and January 31st, 2020. The unit of analysis were patients in consultation. Sociodemographic and clinical variables, and a checklist for use of inhalers were included. Frequencies and proportions were applied for discrete variables, statistics of central tendency and dispersion for continuous variables. Results: A total of 104 patients with an average age of 73.6 ± 10.1 years were included; 57 were women (54.8%). In addition, 48 patients were classified as GOLD-D (46.2%). Similarly, 89 patients reported having received education on the use of bronchodilators (85.6%). The most common were metered-dose (MD) inhalers in 95 cases (91.3%), followed by single-dose dry powder inhalers in eight patients (7.7%). Likewise, 37 patients who used DM without inhalochamber (35.6%) did not comply with the steps of the checklist. In the multidose system, the most performed was to properly close the inhaler and the least performed was to expel the air slowly, avoiding doing so near the inhaler (n=6; 5.7%). Discussion: The characteristics of the technique of using inhalers in patients with COPD were described. Although no patient was able to use the inhaler "perfectly", most have received education from health professionals. Conclusion: A high percentage of patients misuse the devices to deliver bronchodilators. This can negatively impact the control of the disease.

ABSTRACT

Introducción: La Enfermedad Pulmonar Obstructiva Crónica (EPOC) ocasiona en quienes la padecen limitación física, emocional, social y deterioro de la calidad de vida relacionada con la salud (CVRS). El componente educativo es indispensable en todo programa de Rehabilitación Pulmonar (RP), ya que permite mantener resultados de intervención a largo plazo. Objetivo: Comparar el efecto de dos estrategias educativas para pacientes con EPOC desarrolladas en dos programas de RP en Cali, Colombia. Métodos: Estudio prospectivo longitudinal. Durante un periodo de 24 meses se seleccionaron por conveniencia pacientes con EPOC que aceptaron firmar el consentimiento informado. Los pacientes pertenecían a dos programas de RP, uno que realizó RP con educación individual (RPEI) y otro realizó RP con educación individual más grupal (RPEGI). Resultados: Ingresaron 48 pacientes, la disnea medida con la escala mMRC mostró mejoría estadísticamente significativa al inicio y al final del programa para ambos grupos, al igual que la distancia recorrida en el TC6M, con una mejoría en metros de 85,9 ± 12 en el grupo RPEGI y de 47,2 ± 19 en el grupo RPEI. Respecto a la ansiedad y depresión, se presentaron disminuciones significativas en la puntuación del HADS solo para el grupo RPEGI (p = 0,0120 y p = 0,001 respectivamente). En el cuestionario SGRQ todos los dominios presentaron cambios significativos para ambos grupos, excepto para el dominio actividad, que solo tuvo mejoría para el grupo RPEGI (p = 0,000). Finalmente, en el cuestionario LINQ los dos grupos mostraron cambios significativos. Conclusión: Todo programa de RP debe desarrollar un componente de educación. En este estudio, los pacientes con EPOC que recibieron educación individual más grupal presentaron mejores resultados al final de la intervención, especialmente en la ansiedad, depresión y el dominio actividad de la CVRS.


Introduction: Chronic Obstructive Pulmonary Disease (COPD) causes physical, emotional and social limitation and deterioration in health-related quality of life (HRQL) in those who suffer from it. The educational component is essential in any Pulmonary Rehabilitation (RP) program, since it allows maintaining long-term intervention results. The objective of this study was to compare the effect of two educational strategies for COPD patients developed in two PR programs in Cali-Colombia. Methods: Longitudinal prospective study. Patients with COPD who agreed to sign the informed consent were selected, if convenient, during a period of 24 months. The patients belonged to two PR programs, one that carried out PR with individual education (PRIE) and another performed PR with individual education plus group (PRIG). Results: A total of 48 patients were admitted, dyspnea measured with the mMRC scale showed a statistically significant improvement at the beginning and at the end of the program for both groups, as well as the distance traveled in the 6MWT, with an improvement in meters of 85.9±12 in the PRIG group and 47.2±19 in the PRIE group. Regarding anxiety and depression, there were significant decreases in the HADS score only for the PRIG group (p=0.0120 and p=0.001, respectively). In the SGRQ questionnaire, all the domains showed significant changes for both groups, except for the activity domain, which only showed improvement for the PRIG group (p=0.000). Finally, in the LINQ questionnaire, both groups showed significant changes. Conclusion: Every PR program must develop an education component. In this study, COPD patients who received individual plus group education presented better results at the end of the intervention, especially in anxiety, depression and in the HRQoL activity domain.

ABSTRACT

La colangiopatía portal hace referencia a anomalías colangiográficas que se producen en pacientes con cavernomatosis portal, siendo progresiva, cursando con enfermedad biliar sintomática y anomalías graves de las vías biliares. Y, representa una complicación infrecuente de la hipertensión portal. Se describe el caso de un hombre de 53 años, con historia de larga data de hipertensión portal nocirrótica y cavernomatosis portal, quien presentó un episodio de enfermedad biliar obstructiva sintomática, y en estudios se documentó tejido fibrótico de extensión periportal ascendente con compresión extrínseca del colédoco distal y dilatación de la vía biliar extra e intrahepática. Por lo que se procedió a colangiopancreatografía retrógrada endoscópica, realizándose tratamiento paliativo, con papilotomía pequeña y colocación de endoprótesis biliar plástica, siendo exitoso por ausencia de complicaciones procedimentales, y mejoría clínica y parámetros bioquímicos. Finalmente, recibiendo de alta con indicación de seguimiento prioritario para recambios periódicos de endoprótesis biliares, y valoración por hepatología. La colangiopatía portal es una entidad rara que debe sospecharse en sujetos con hipertensión portal de origen no-cirrótico, con hallazgos imagenológicos de estenosis, angulaciones o dilataciones segmentarias, su tratamiento debe ser individualizado, y la terapia endoscópica es de elección en enfermedad biliar sintomática.


Portal cholangiopathy refers to cholangiographic abnormalities occurring in patients with portal cavernomatosis, being progressive, presenting with symptomatic biliary disease and severe biliary tract abnormalities. And, it represents an infrequent complication of portal hypertension. We describe the case of a 53-year-old man with a long history of non-cirrhotic portal hypertension and portal cavernomatosis, who presented an episode of symptomatic obstructive biliary disease, and studies documented fibrotic tissue of ascending periportal extension with extrinsic compression of the distal common bile duct and dilatation of the extra and intrahepatic biliary tract. Therefore, endoscopic retrograde cholangiopancreatography was performed, and palliative treatment with small papillotomy and placement of a plastic biliary endoprosthesis was successful due to the absence of procedural complications, and clinical improvement and biochemical parameters. Finally, the patient was discharged with indication of priority follow-up for periodic replacement of biliary stents, and evaluation by hepatology. Portal cholangiopathy is a rare entity that should be suspected in subjects with portal hypertension of non-cirrhotic origin, with imaging findings of stenosis, angulations or segmental dilatations, its treatment should be individualized, and endoscopic therapy is of choice in symptomatic biliary disease.
