ABSTRACT
The C-C chemokine receptor type 5 (CCR5) plays a role in the immunopathogenesis of chronic kidney disease (CKD). Exercise has anti-inflammatory properties that may contribute to the rehabilitation of CKD patients. To date, the impact of the intradialytic exercise on CCR5 expression in monocytes and lymphocytes of CKD patients is unknown. We aimed to evaluate the effects of an acute intradialytic moderate-intensity exercise on CD4+CCR5+ T-cells and CD14+CCR5+ monocytes of elderly individuals with Chronic Kidney Disease (CKD). Eight CKD elderly patients performed a single bout of 20 min intradialytic exercise and a control hemodialysis (HD) session. Blood samples were collected at baseline, during and immediately after the trials. HD therapy increased the peripheral frequency of CD4+CCR5+ T-cells. The systemic CCL5 levels and the peripheral CD14+CCR5+ proportions increased during and after HD therapy. No significant alterations in CD4+CCR5+ and CD14+CCR5+ proportions or CCL5 levels were identified in CKD patients during and after intradialytic exercise. A negative correlation between the peripheral frequency of CD14+CCR5+ and the creatinine levels was identified in the intradialytic exercise session. A single moderate-intensity intradialytic exercise imposes an immunomodulatory impact in CKD elderly patients, preventing an excessive inflammatory response induced by hemodialysis.

Abstract Introduction: Muscle dysfunction is one of the major changes found in chronic obstructive pulmonary disease (COPD) and associated with loss of functionality, morbidity and mortality. Objective: correlate two strength assessment methods: manual dynamometry for handgrip strength and isokinetic dynamometry for quadriceps strength in patients with COPD, and assess the body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE), quality of life and muscle strength. Method: twenty-five patients with moderate to very severe COPD were evaluated by pulmonary function parameters, anthropometric variables, functional capacity, via the six-minute walk test, dyspnea, applying the modified Medical Research Council (mMRC) scale, BODE, quality of life, using the Saint George's Respiratory Questionnaire (SGRQ), handgrip strength with manual dynamometer and quadriceps force using an isokinetic dynamometer. Muscle strength was assessed with a manual portable dynamometer and isokinetic dynamometer. For statistical analysis, ANOVA with Bonferroni's post-test, the chi-squared test and Pearson's correlation coefficient were used. Results: There was a strong correlation between the strength measurements and the two instruments (torque and quadriceps extension power with right handgrip strength: r = 0.74; p <0.001). The patients classified as very severe exhibited worse performance in the strength tests when compared to the moderate group, albeit with no statistically significant difference. Conclusion: In muscle strength measurements, a strong correlation was detected between the isokinetic dynamometer for quadriceps and the manual dynamometer for handgrip strength. These findings indicate that, in clinical practice, the manual dynamometer for handgrip strength could be used to assess peripheral muscle strength in patients with COPD.
Resumo Introdução: Disfunção muscular é uma das principais alterações encontradas na Doença Pulmonar Obstrutiva Crônica (DPOC), estando relacionada com perda da funcionalidade, morbidades e mortalidade. Objetivo: Correlacionar dois métodos de avaliação de força: dinamometria manual para força de preensão palmar (FFP) e dinamometria isocinético para força de quadríceps em pacientes com DPOC, e avaliar dispneia, Body mass index, airway Obstruction, Dyspnea, and Exercise capacity (BODE), qualidade de vida e força muscular. Método: Foram avaliados 25 pacientes com DPOC moderada a muito severa quanto a espirometria e antropometria; capacidade funcional através da distância percorrida no teste de caminhada de seis minutos (DTC6); dispneia através da escala modificada Medical Research Council; BODE; e qualidade de vida através do Saint George's Respiratory Questionnaire. A força muscular foi avaliada através de dinamômetro portátil manual e dinamômetro isocinético. Para estatística utilizou-se ANOVA e pós-teste de Bonferroni, teste de Qui-quadrado e Coeficiente de Correlação de Pearson. Resultados: Houve correlação entre medidas de força com os dois instrumentos (torque e potência de extensão do quadríceps com FPP direita: r=0,74; p<0,001). Não houve diferença nos testes de força em relação à gravidade da doença. Além disso, o DTC6 não mostrou diferença significativa entre os grupos e a qualidade de vida mostrou-se pior no grupo muito severo, tendo diferença significativa em relação ao grupo moderado. Conclusão: Foi encontrada forte correlação entre as medidas de força realizadas com dinamômetro isocinético para o quadríceps e dinamômetro manual para FPP. Esses achados indicam que, na prática clínica, o dinamômetro manual pode ser utilizado para avaliação da musculatura periférica em pacientes com DPOC.
ABSTRACT
OBJECTIVE: Mini-Mental State Examination (MMSE) results are strongly influenced by educational level. The Brief Cognitive Screening Battery (BCSB) is an alternative assessment tool that provides more accurate results in individuals with less education. Our aim was to compare the MMSE and BCSB as screening tests. METHODS: The MMSE and BCSB were assessed in 112 participants by two evaluators blind to the other test's result. Participants were classified according to their level of education. The influence of education level was analyzed using the Kruskal-Wallis and multiple comparison tests. RESULTS: Scores of the MMSE (p < 0.0001) and the clock-drawing test (p < 0.0001) were influenced by education level but the delayed recall test score was not (p = 0.0804). The verbal fluency test (p = 0.00035) was influenced only by higher educational levels. It took three minutes less to apply the MMSE than to apply the BCSB (p < 0.0001). CONCLUSIONS: These findings suggest that the delayed recall test and the verbal fluency test of the BCSB are better than the MMSE and clock-drawing test as tools for evaluating cognition in people with limited education.

Resumo Os resultados do Mini-Exame de Estado Mental (MEEM) são consideravelmente influenciados pelo nível de escolaridade. A Bateria Breve de Rastreio Cognitivo (BBRC) é uma ferramenta de rastreamento cognitivo alternativa que fornece resultados mais acurados em indivíduos com menor nível de escolaridade. Objetivo: Comparar o MEEM e a BBRC como testes de rastreamento cognitivo. Métodos: 112 participantes foram submetidos ao MEEM e a BBRC por 2 avaliadores cegos para o resultados do outro teste. Os participantes foram classificados de acordo o nível de escolaridade. A influência do nível de escolaridade foi analisada utilizando o teste de Kruskal-Wallis e o teste de comparações múltiplas. Resultados: As pontuações do MEEM (p < 0,0001) e do teste do desenho do relógio (p < 0,0001) foram influenciadas pelo nível de escolaridade, porém o teste de memória tardia não sofreu influência do nível de escolaridade (p = 0,0804). O teste de fluência verbal (p = 0,00035) foi influenciado apenas pelos níveis educacionais mais altos. A aplicação do MEEM levou 3 minutos a menos que a da BBRC (p < 0,0001). Conclusão: Os achados desse estudo sugerem que o teste de memória tardia e o teste de fluência verbal da BBRC são mais adequados que o MEEM e o teste do desenho do relógio como ferramentas para avaliação cognitiva em populações com menor nível educacional.

O presente estudo tem por objetivo avaliar o efeito do sobrepeso e da obesidade sobre a função pulmonar (FP) e a qualidade de vida (QV) em idosos vinculados ao Programa Estratégia de Saúde da Família (ESF) em Cruz Alta-RS. Foram avaliados cem idosos, sendo noventa mulheres. A FP foi avaliada através da Capacidade Vital Forçada (CVF), Volume Expiratório Forçado no Primeiro Segundo (VEF1 ) e Pico de Fluxo Expiratório (PFE). O questionário Medical Outcome Study 36-Item Short-Form Health Survey (SF-36) foi utilizado para avaliar a QV. Observaram-se 54 indivíduos com sobrepeso ou obesos. A FP apresentou-se dentro da normalidade. As maiores pontuações de QV foram nos domínios Capacidade Funcional (CF), Estado Geral de Saúde (EGS) e Aspectos Sociais (AS). Os indivíduos com sobrepeso e obesos apresentaram escore inferior nos domínios Vitalidade e AS quando comparado aos eutróficos (p = 0,01 e p = 0,03, respectivamente). Foram encontradas correlações inversas entre IMC e os Domínios Vitalidade (r = -0,23, p = 0,01), AS (r = -0,23, p = 0,01) e AE (r = -0,27, p = 0,01). Conclui-se que os idosos avaliados apresentaram níveis satisfatórios de FP e QV, entretanto o sobrepeso e a obesidade influenciaram negativamente a QV. (AU)
The present study aims to evaluate the influence of overweight and obesity on the pulmonary function (PF), and quality of life (QoL) in elderly people linked to the Family Health Strategy Program in Cruz Alta-RS. We evaluated hundred elderly, ninety women. The PF was measured by forced vital capacity (FVC), forced expiratory volume in the first second (FEV1 ) and peak expiratory flow (PEF). The Medical Outcome Study 36-Item Short-Form Health Survey (SF-36) was used to assess QoL. It was observed 54 people with overweight or obesity. The PF was within the normal range. The higher QL scores were in the Functional Capacity (FC), General Health (EGS), and Social Aspects (SA). The overweight, and obese individuals showed lower scores in the Vitality and SA domains when compared to the eutrophic ones (p = 0.01 and p = 0.03, respectively). There was an inverse correlation between the Pain domain and the PF. Furthermore, inverse correlations were found between BMI and Vitality (r = -0.23, p = 0.01), AS (r = -0.23, p = 0.01) and EA (r = -0.27, p = 0.01) domains. Then, it was conclude that the evaluated subjects presented satisfactory levels of PF and QoL. However, high levels of BMI negatively influence their QoL. (AU)

This study aimed to evaluate the immune profile of lean and overweight-obese COPD patients. Forty patients with moderate to very severe COPD were divided into lean group (n=20; aged 62.00±8.91years; BMI 22.26±1.65kg/m2) or overweight-obese group (n=20; aged 65.40±6.69years; BMI 29.19±3.55kg/m2). The cytokine profile (IL-2, IL-4, IL-6, IL-10, INF-γ, and TNF-α) was evaluated through the Cytometric Bead Array technique, and the expression of CD4, CD8, CD25, CD45ra, CD45ro, CD69, CD195(CCr5) and HLA-DR were evaluated in CD3+ T-cells. Overweight-obese COPD group had lower levels of IL-2 (p=0.01) and higher INF-γ levels (p=0.02) and IL-6 (p=0.003) than lean COPD. Lean COPD patients had higher CD25+ (p=0.01), CCr5 (p=0.04) and HLA-DR (p=0.007) expression on T cell surface compared to overweight-obese COPD participants. These changes are related to immune dysfunction of obesity, and excess of fat mass in COPD can be a key factor to low T-cells activation.

PURPOSE: To evaluate the acute response of natural killer (NK) cell subsets of chronic kidney disease patients submitted to intradialytic exercise in a randomized crossover study. METHODS: Nine patients were submitted to a single bout of 20-min intradialytic exercise and a control hemodialysis (HD) session with an interval of 7 days between them. Peripheral blood sample was collected at baseline, during HD and immediately after HD in each trial to evaluate the peripheral frequency of NK cells and their subsets (CD3-CD56bright and CD3-CD56dim), systemic cortisol concentrations, C-reactive protein (CRP), creatine kinase activity (CK), and urea and creatinine levels. RESULTS: HD therapy induced a significant decrease in NK cells frequency (p = 0.039), NK CD3-CD56bright cells (p = 0.04), and CD3-CD56dim cells (p = 0.036). On the other hand, no significant alterations were observed in NK cells and NK subsets during and after intradialytic exercise trial (p > 0.05). Neither trial altered CRP levels or serum CK activity during and after HD therapy (p > 0.05). However, HD therapy increased cortisol concentrations after HD therapy (p = 0.034). CONCLUSIONS: This study suggests the potential role of intradialytic exercise to prevent the decrease in peripheral frequency of NK cell subsets during HD therapy. Moreover, moderate intensity intradialytic exercise did not exacerbate the systemic inflammation or induce muscle damage during HD therapy.

INTRODUCTION: The application of expiratory positive airway pressure (EPAP) in patients with COPD during exercise may reduce dynamic hyperinflation, while, on the other hand, it can increase the resistive work of breathing. Therefore, we evaluated the effects of 2 intensities of EPAP during exercise on tolerance, dynamic hyperinflation, and dyspnea in subjects with moderate to very severe COPD. METHODS: We performed a cross-sectional, experimental, 4-visit study. In visit 1, subjects performed symptom-limited cycling incremental cardiopulmonary exercise test (CPET). In visits 2-4, at least 48 h apart, in a randomized order, subjects performed constant CPET without EPAP, EPAP with 5 cm H2O (EPAP5), or EPAP with 10 cm H2O (EPAP10). RESULTS: The study included 15 non-hypoxemic subjects ranging from moderate to very severe COPD (mean FEV1 = 35 ± 11% predicted). Increasing intensities of EPAP during constant CPET tended to cause progressive reduction in exercise tolerance (P = .11). Of note, 10 of 15 subjects demonstrated significantly shorter average exercise duration with EPAP10 compared to the test without EPAP (-151 ± 105 s, P = .03 or -41 ± 26%). Minute ventilation increment was constrained by EPAP, secondary to a limited increase in tidal volume (P = .01). Finally, dyspnea sensation and serial measurements of inspiratory capacity during exercise were similar when comparing the three interventions at isotime and at end-constant CPETs. CONCLUSIONS: The application of EPAP5 or EPAP10 during exercise tended to cause a progressive reduction in exercise tolerance in subjects with COPD without improvement in dyspnea or dynamic hyperinflation at equivalent exercise duration.

Sporadic colorectal cancer (CRC) is traditionally diagnosed after de sixth decade of life, although a small percentage of cases are diagnosed in patients under 40 years of age, and incidence is increasing. There exists a great volume of controversy regarding clinical outcome of young patients diagnosed with colorectal cancer (CRC) when compared to elder counterparts. Our aims were to evaluate the rate of CRC in young patients, to review the pertaining literature and to discuss outcomes and clinical prognosis. A retrospective review involving patients with CRC was undertaken, focusing on age at diagnosis. The information extracted from this literature review showed a trend towards a decreased incidence in older people with an opposite effect among adolescents and young adults. Moreover, biological aggressiveness in young adults diagnosed with CRC has not been fully recognized, although it is usually diagnosed later and in association with adverse histological features. Besides that, these features don't affect outcome. These apparent increase in CRC incidence among young patients during the last decades raises the need for a greater suspicious when evaluating common symptoms in this group. Thus, educational programs should widespread information for both population and physicians to improve prevention and early diagnosis results.
O câncer colorretal (CCR) esporádico é tradicionalmente diagnosticado após a sexta década de vida, embora uma pequena porcentagem de casos seja diagnosticada em doentes abaixo dos 40 anos de idade, e a incidência está aumentando. Existe uma grande controvérsia a respeito da evolução clínica de doentes jovens portadores de CCR em comparação aos mais idosos. Os objetivos deste estudo foram avaliar a prevalência de CCR em doentes jovens, rever a literatura pertinente e discutir suas características mais importantes nesta faixa etária. Para tanto realizou-se revisão da literatura envolvendo doentes com CCR com foco na idade ao diagnóstico. A informação extraída da revisão de literatura demonstrou uma tendência de redução da incidência em pessoas mais idosas com efeito oposto em adolescentes e adultos jovens. Sua agressividade biológica ainda não foi claramente reconhecida, embora seja usualmente diagnosticado mais tardiamente e em associação com características histológicas adversas. Apesar disso, estas características não afetam a evolução. Este aparente aumento na incidência de CCR entre pacientes jovens durante as últimas décadas levanta a necessidade de uma maior suspeita diagnóstica na avaliação de sintomas comuns neste grupo. Assim, programas educacionais devem disseminar informação tanto para população como para médicos a fim de melhorar a prevenção e o diagnóstico precoce.

Abstract Introduction: Hemodialysis contributes to increased oxidative stress and induces transitory hypoxemia. Compartmentalization decreases the supply of solutes to the dialyzer during treatment. The aim of this study was to investigate the acute effects of intradialytic aerobic exercise on solute removal, blood gases and oxidative stress in patients with chronic kidney disease during a single hemodialysis session. Methods: Thirty patients were randomized to perform aerobic exercise with cycle ergometer for lower limbs during 30 minutes with intensity between 60-70% of maximal heart rate, or control group (CG). Blood samples were collected prior to and immediately after exercise or the equivalent time in CG. Analysis of blood and dialysate biochemistry as well as blood gases were performed. Mass removal and solute clearance were calculated. Oxidative stress was determined by lipid peroxidation and by the total antioxidant capacity. Results: Serum concentrations of solutes increased with exercise, but only phosphorus showed a significant elevation (p = 0.035). There were no significant changes in solute removal and in the acid-base balance. Both oxygen partial pressure and saturation increased with exercise (p = 0.035 and p = 0.024, respectivelly), which did not occur in the CG. The total antioxidant capacity decreased significantly (p = 0.027). Conclusion: The acute intradialytic aerobic exercise increased phosphorus serum concentration and decreased total antioxidant capacity, reversing hypoxemia resulting from hemodialysis. The intradialytic exercise did not change the blood acid-base balance and the removal of solutes.
Resumo Introdução: A hemodiálise contribui para aumentar o estresse oxidativo e induz a hipoxemia transitória. A compartimentalização dos solutos diminui sua oferta para o dialisador durante o tratamento. O objetivo deste estudo foi investigar os efeitos agudos do exercício aeróbio intradialítico sobre a remoção de solutos, gasometria e estresse oxidativo em pacientes com doença renal crônica durante uma sessão de hemodiálise. Métodos: Trinta pacientes foram randomizados para realizar exercício aeróbio com cicloergômetro para membros inferiores durante 30 minutos com intensidade entre 60-70% da frequência cardíaca máxima, ou grupo controle (GC). Amostras sanguíneas foram coletadas antes e imediatamente após o término do exercício ou no período equivalente no GC. Análises da bioquímica do sangue e dialisato e gasometria foram realizadas. A massa removida e a depuração dos solutos foram calculadas. O estresse oxidativo foi determinado pela peroxidação lipídica e capacidade antioxidante total. Resultados: As concentrações séricas dos solutos aumentaram com o exercício, mas somente o fósforo mostrou elevação significativa (p = 0.035). Não houve modificações significantes na remoção de solutos e no equilíbrio ácido-básico. A pressão parcial e a saturação de oxigênio aumentaram com o exercício (p = 0.035 e p = 0.024, respectivamente), o que não ocorreu no GC. A capacidade antioxidante total diminuiu significativamente (p = 0.027). Conclusão: O exercício aeróbico intradialítico agudo aumentou a concentração sérica de fósforo e diminuiu a capacidade antioxidante total, revertendo a hipoxemia resultante da hemodiálise. O exercício intradialítico não alterou o equilíbrio ácido-básico e a remoção de solutos.

The aim of this study was to verify the effects of the Pilates Method (PM) training program on the thickness of the abdominal wall muscles, respiratory muscle strength and performance, and lung function. This uncontrolled clinical trial involved 16 sedentary women who were assessed before and after eight weeks of PM training. The thickness of the transversus abdominis (TrA), internal oblique (IO) and external oblique (EO) muscles was assessed. The respiratory muscle strength was assessed by measuring the maximum inspiratory (MIP) and expiratory (MEP) pressure. The lung function and respiratory muscle performance were assessed by spirometry. An increase was found in MIP (p = 0.001), MEP (p = 0.031), maximum voluntary ventilation (p = 0.020) and the TrA (p < 0.001), IO (p = 0.002) and EO (p < 0.001) thickness after the PM program. No alterations in lung function were found. These findings suggest that the PM program promotes abdominal wall muscle hypertrophy and an increase in respiratory muscle strength and performance, preventing weakness in abdominal muscles and dysfunction in ventilatory mechanics, which could favor the appearance of illnesses.

BACKGROUND AND AIM: Physical exercise is a key part of rehabilitation programs in chronic obstructive pulmonary disease (COPD) patients, although it could modulates immune system responses by altering the cytokine profile of such individuals. Furthermore, the degree of severity of COPD could influence the inflammatory response induced by exercise. To evaluate the cytokine profile of individuals with different degrees of COPD in response to a 6-min walk test (6MWT). METHODS: Forty-one patients with COPD were classified according to the severity of the disease by Global Initiative for Chronic Obstructive Lung Disease method: moderate = 14 individuals; severe = 14 individuals; very severe = 13 individuals. Blood sample collection was performed in the subjects pre and post a 6MWT. Cytokine plasma levels were analyzed to determine the cytokine profile using a Cytometric Bead Array technique (Becton Dickinson, San Jose, CA, USA) assay in flow cytometry. RESULTS: A significant difference was observed in the interleukin (IL)-6 levels after test between very severe and severe groups (P = 0.036). Also, lower levels of IL-4 were observed in the severe group compared with the very severe and the moderate groups in the pretest (P = 0.029; P = 0.003, respectively), and different values between the moderate and severe groups in the post-test (P = 0.044). A significant time pre-post effect was found in the IL-4 levels on the very severe group (P = 0.046). CONCLUSION: After the 6MWT, a discrete inflammatory response was observed in COPD patients, independent of the degree of severity. The results concerning IL-4 and IL-6 levels can be indicative of an attempt to control inflammation after the 6MWT in COPD patients.

BACKGROUND: Immunological dysfunctions and a pro-inflammatory environment are associated with higher risk of cardiovascular diseases in chronic kidney disease (CKD). Physical exercise can be an important anti-inflammatory strategy, but the effects in CKD remain poorly investigated. OBJECTIVE: Evaluate the acute inflammatory response to intradialytic exercise in the peripheral blood of individuals with CKD. METHODS: Nine patients, of both genders, with CKD and allocated in the ambulatory of hemodialysis of Hospital Ernesto Dornelles (Brazil), performed two sessions of hemodialysis (HD) in random form: aerobic intradialytic exercise sessions (EX, 20 min of moderate exercise in cycle-ergometer) and a control hemodialysis session (CON). Peripheral blood collection was made at the baseline, during and immediately after HD to evaluate the cytokine profile: interleukin-6, interleukin-10 (IL-10), interleukin-17a (IL-17a), interferon-gamma (INF-γ) and tumoral necrosis factor-alpha (TNF-α). RESULTS: INF-γ decreased during HD when compared with the pre moment in both sessions, while an increase in post HD was only found in the CON session. IL-17 was higher in post when compared with during HD in both sessions. In addition to the time effect, IL-10 presented a time × group interaction and the relative changes were significantly higher in EX when compared with the CON session. The relative changes in TNF-α tended to be higher in CON when compared with EX immediately post HD session. CONCLUSIONS: These data indicate that 20 min of intradialytic exercise have modest effect in systemic inflammation. However, the significant increase in IL-10 may indicate an immunoregulatory effect of physical exercise.

RATIONAL: Patients under regular dialysis can also present alterations in the cardiovascular, musculoskeletal, and metabolic systems. OBJECTIVES: The aim of this study is to compare the effects of strength and aerobic exercises performed during hemodialysis (HD) in individuals with chronic renal disease. MATERIALS AND METHODS: Randomized clinical trial. It was developed as a program of exercises three times a week, in the first 2 h of HD for 8 weeks. The patients were divided into three groups: control (Group 1, n: 11), strength (Group 2, n: 11), and aerobic (Group 3, n: 10). G1 has not developed any type of physical training; G2 utilized a training load of 40% of one repetition maximum (1RM) with anklets, and developed three series of 15 repetitions. G3 pedaled seated in the dialysis seat, during 20 min, in an ergometric bicycle, with intensity regulated by the perceived effort scale. Before and after 8 weeks, the following variables were evaluated: respiratory muscular strength, pulmonary function, functional capacity, blood biochemistry, and quality of life. MAIN FINDINGS: In the pre- and post-training comparison, there was statistically significant improvement (p < 0.05) in the maximal inspiratory pressure (MIP), number of steps achieved (NSA), and quality of life (QoL) in the trained groups, as compared to the non-exercised group (G1). CONCLUSIONS: The strength and aerobic exercises developed during HD can improve the respiratory muscular strength, functional performance, and quality of life, when compared to individuals presenting the disease who have not developed any type of physical training.

INTRODUCTION: Pediatric patients undergoing kidney transplantation can present changes in pulmonary function and functional capacity for exercise. OBJECTIVE: To evaluate the functional capacity and pulmonary function in children and adolescents undergoing kidney transplantation. METHOD: Children and adolescents aged six to 18 years of age were evaluated in Outpatient Clinic of Nephrology, Hospital da Criança Santo Antônio, Santa Casa de Porto Alegre, RS, Brazil in period the june of 2010 the march of 2011. Pulmonary capacity was assessed by spirometry and maximal respiratory pressures and functional capacity through 6-minute walk test (6MWT). RESULTS: The sample comprised 25 patients, 14 (56%) males with a mean age of 13.5 ± 3.3 years. From, 19 (76%) underwent dialysis before transplantation. Mean forced vital capacity (FVC) was 97.91 + 24.32% and forced expiratory volume in one second (FEV1) 100.53 + 17.66% from predicted value. In the 6MWT, the patients walked 229.14 meters less than predicted (p < 0.001). The maximum inspiratory pressure (MIP) was significantly lower than predicted, and the difference in cmH2O -24.63 (p = 0.03), as the maximum expiratory pressure (MEP), with a difference of 49.27 cmH2O (p < 0.001). By correlating, functional capacity, spirometry and maximal respiratory pressures, find an association between FVC and 6MWT (r = 0.52, p = 0.01) and FVC and MIP (r = 0.54, p = 0.01). CONCLUSION: Reduced functional capacity and maximum respiratory pressures were diagnosed in a small cohort of pediatric patients after kidney transplantation. Better the functional capacity and PiMáx better the FVC.
