RESUMO

Las lesiones bronquiales preinvasivas se detectan con escasa frecuencia mediante broncofibroscopia convencional y su manejo posterior sigue planteando numerosas cuestiones en cuanto a la periodicidad y tiempo de seguimiento, así como la necesidad de empleo de broncofibroscopia con fluorescencia y realización de terapia endobronquial. Se presenta el caso de un varón diagnosticado de displasia bronquial moderada mediante broncofibroscopia convencional de luz blanca


reinvasive bronchial lesions are detected infrequently by conventional bronchoscopy. Further management still poses many questions about the frequency, time tracking, and the need for use of fluorescence bronchoscopy and endobronchial therapy. We report the case of a man diagnosed with moderate bronchial dysplasia by conventional bronchoscop

RESUMO

OBJETIVOS: establecer la frecuencia del síndrome de apneas-hipopneas del sueño (SAHS) en pacientes con cardiopatía isquémica y valorar si la sintomatología puede ayudar a sospechar el diagnóstico en esta población. PACIENTES Y MÉTODOS: los pacientes elegibles fueron remitidos consecutivamente, en estabilidad clínica, a la Unidad de Trastornos Respiratorios del Sueño tras un ingreso hospitalario por cardiopatía isquémica. A todos se les realizó una historia clínica y exploración física, con especial atención a los hábitos y características del sueño, síntomas nocturnos/diurnos, y comorbilidad. El diagnóstico de SAHS fue considerado si el sujeto presentó un IAH ≥ 10 /hora, registrado por poligrafía respiratoria. RESULTADOS: fueron incluidos 55 enfermos, realizándose el diagnóstico de SAHS en 29 (53%), de los que sólo 1 había sido diagnosticado previamente. Respecto al grupo control, los pacientes con SAHS presentaron mayor porcentaje de factores de riesgo vascular, incluyendo hipertensión, diabetes mellitus y dislipemia, aunque sin alcanzar significación estadística. La sintomatología en ambos grupos fue similar, salvo las apneas observadas durante el sueño, que fueron significativamente más abundantes en el grupo con SAHS (p = 0,006).CONCLUSIONES: en pacientes con cardiopatía isquémica, el porcentaje con SAHS es mayor que el descrito en la población general, y la mayoría de los casos no están diagnosticados. El cuadro clínico es inespecífico, y sólo las apneas observadas son síntoma de que puede aumentar la sospecha diagnóstica de SAHS


OBJECTIVES: establish the percentage of sleep apnea-hypopnea syndrome (SAHS) in patients with ischemic heart disease and assess whether the symptoms can help to suspect the diagnosis in this population. PATIENTS AND METHODS: elegible patients were consecutively referred in clinical stability after an admission for ischemic heart disease to the unit of sleep-disorder breathing. All patients underwent a medical history and physical examination with special attention to the habits and characteristics of sleep, nighttime and daytime symptoms, and comorbidity. The diagnosis of SAHS was considered if the subject had an AHI ≥ 10/ h, by using a respiratory poligraphy. RESULTS: we included 55 patients, performing diagnosis of SAHS in 29 (53%) of them. Only one patient was previously diagnosed. Respect to control group, patients with SAHS had a higher percentage of vascular risk factors, including hyper-tension, diabetes mellitus and dyslipidemia, although not statistically significant (p > 0,05). The symptoms in both groups was similar, except witnessed apneas during sleep was signifiantly higher in the SAHS group (p = 0,006).CONCLUSIONS: in patients with ischemic heart disease the per-centage of SAHS is higher than in the general population, most of the patients are not previously diagnosed. The semiology is nonspecific and the witnessed apneas are the only symptom that can increase the diagnostic suspicion

RESUMO

Objetivo: Se diseña un estudio con el objetivo de valorar el papel de la proteómica en la identificación de proteínas diferenciales en pacientes con SAHS. Pacientes y métodos: Fueron incluidos 37 enfermos con sintomatología sugestiva de SAHS y un IAH ≥ 5 y un grupo control compuesto por 18 sujetos roncadores, emparejados por IMC, género y edad con el grupo con SAHS en los que se descartó un SAHS (IAH < 5). En ambos grupos se excluyeron a los sujetos que estaban diagnosticados de enfermedad crónica avanzada. En primer lugar se efectuó electroforesis bidimensional que comparó los geles de ambos grupos y estableció los spots diferenciales (sobreexpresión > 2,5 veces el grupo control y subexpresión < 0,5 veces por debajo del grupo control). Posteriormente se realizó espectrometría de masas mediante MALDI /TOF-TOF (matrix laser assisted desorption- time of flight).Resultados: Respecto al grupo control, IAH = 3,5 (3-4,1), en los enfermos con SAHS, IAH = 53 (27-74), mediante MALDI/TOF-TOF se identificó una proteína sobreexpresada, la haptoglobina que se ha relacionado con mayor riesgo vascular en pacientes con SAHS. Igualmente se identificaron dos proteínas subexpresadas, la albúmina y serotransferrina, proteínas que pueden facilitar una disminución de las defensas antioxidantes en el SAHS. Conclusiones: Se aporta el primer perfil proteómico diferencial en pacientes adultos con SAHS. Se demuestra la validez de la proteómica para identificar un conjunto de proteínas diferenciales que puedan ser útiles para el diagnóstico o para establecer un perfil de riesgo vascular (AU)


Objective: a study was designed to assess the role of proteomics in the identification of differential proteins in patient with obstructive sleep apnea-hypopnea syndrome (OSAH). Patients and methods: Thirty seven patients with symptoms suggestive of OSAH and a apnea-hypopnea index (AHI) ≥ 5 were included in the study, and a control group was made up of 18 snorers, matched for BMI, gender and age with the OSAH group in which one OSAH was discarded (AHI < 5). Subjects diagnosed with advanced chronic disease were excluded from both groups. First, two-dimensional electrophoresis was performed, which compared the gels of both groups and established the differential spots (over-expression > 2.5 times the control group and under-expression < 0.5 times below the control group). Subsequently, a mass spectrometry was performed by means of MALDI / TOF-TOF (matrix laser assisted desorption - time of flight). Results: Regarding the control group, mean AHI = was 3.5 (3-4.1), and in those affected with OSAH it was, AHI = 53 (27-74). , Aan over-expressed protein, haptoglobin, was identified by means of MALDI/TOF-TOF, which has been related with a greater vascular risk in patient with OSAH. Likewise, two under-expressed proteins, albumin and serotransferrin, were identified, proteins that can facilitate a decrease of the anti-oxidant defences in OSAH. Conclusions: An initial differential proteomic profile in mature patients with OSAH was found. The legitimacy of proteomics to identify a group of differential proteins that could be useful to diagnosis or establish a profile of vascular risk has been demonstrated (AU)

RESUMO

Introducción: El síndrome de apneas-hipopneas del sueño (SAHS) es una enfermedad frecuente y asociada a morbimortalidad en estadios graves. Se postula que el SAHS puede tener una expresión proteíca diferencial respecto a un grupo de pacientes sin SAHS. Se diseña un trabajo para determinar si un estudio proteómico es capaz de identificar proteínas sobreexpresadas en enfermos con SAHS leve. Métodos: A los sujetos se les realizó una historia clínica, exploración física, bioquímica general, polisomnografía diagnóstica y estudio proteómico mediante iTRAQ (isobaric tags for relative and absolute quantification). Se incluyeron 11 pacientes con SAHS, índice de apneas-hipopneas (IAH) ≥ 5, cuyos resultados fueron comparados con un grupo sin SAHS (IAH < 5). Fueron excluidos aquellos con SapO2 ≤ 93% y enfermedad grave de órgano. Resultados: los pacientes presentaron un índice de apneashipopneas de 12 ± 3 y una edad media de 44 ± 7 años. En el SAHS se observaron 3 proteínas sobreexpresadas (ratio > 1.3) respecto al grupo control. Estas proteínas fueron la PRO0684 (gi-6855601), la immunoglobulina lambda de cadena corta VLJ (gi-21669561) y el kininogeno HMW precursor (gi-68785). Las principales funciones y procesos biológicos en los que están involucrados son la inflamación, respuesta inmune y coagulación. Conclusiones: Respecto a un grupo control, en los pacientes con SAHS se observan proteínas sobreexpresadas. Estas proteínas pueden ser de ayuda para el diagnóstico o para aumentar el conocimiento en procesos fisiopatológicos subyacentes. No obstante, son datos preliminares, cuyo alcance debe establecerse en estudios posteriores (AU)


Introduction: The apnea-hypopnea sleep syndrome (AHSS) is a frequent illness, associated to morbidity and mortality in its most serious stages. It has been postulated that AHSS may have a differential protein expression with regards to a group of patients without AHSS. A study has been designed to determine whether or not a proteomic study is able to identify the overly expressed proteins in patients with minor AHSS. Method: Full clinical background was noted for the subjects, as well as physical examination, general biochemical tests, diagnostic polysomnography and proteomic study using iTRAQ (isobaric tags for relative and absolute quantification). Included in the study were 11 patients with AHSS, an apnea-hypopnea index (AHI) ≥ 5, whose results were compared to a control group without AHSS (AHI < 5). Those with SapO2 ≤ 93% and serious organ disease were excluded. Results: the patients presented an apnea-hypoapnea index of 12 ± 3 and an average age of 44 ± 7 years. In AHSS, 3 overly expressed proteins were observed (ratio > 1.3) with regards to the control group. These proteins were PRO0684 (gi-6855601), short immunoglobulin lambda chain VLJ (gi-21669561) and the kininogen HMW precursor (gi-68785). The main functions and biological processes include inflammation, immune response and coagulation. Conclusions: With regards to the control group, patients with AHSS showed overly expressed proteins. These proteins may be helpful in the diagnosis or in increasing knowledge about underlying physical-pathological processes. Nevertheless, this data is preliminary, with scope of which must establish future studies (AU)

RESUMO

UNLABELLED: INTRODUCTIóN: After cystic fibrosis, lung transplantation (LT) patients with prior chronic obstructive pulmonary disease (COPD) are most susceptible to loss of bone mineral density (BMD). OBJECTIVES: To determine the prevalence of BMD loss among COPD patients being evaluated as LT candidates, seeking to identify, their risk profile. PATIENTS AND METHODS: This cross-sectional study included COPD patients who were LT candidates evaluated from January 2007 to December 2009. To identify patients at risk of fracture, BMD at the femoral neck and lumbar spine was assessed by bone densitometry. For categorization, we followed the World Health Organization criteria. To evaluate the risk profile, we recorded data on age, sex, smoking, lung function forced expiratory volume in 1 second, distance covered in the 6-minute walk test, body mass index, and degree of dyspnea. We recorded individual data as well as grouped them the multidimensional BODE (Body mass index Obstruction Dyspnea Exercise capacity) index. RESULTS: The study cohort consisted of 64 patients (51 men and 13 women). The overall prevalence of low BMD in any of the explored territories was 84.4%, affecting 88.2% of men and 69.2% of women. Osteoporosis was identified in 56.2% of patients, reaching a serious degree in 11/64 (17.2%). No significant differences were observed in any evaluated parameter when patients were separated into those with normal versus pathological BMD. When patients with osteopenia and osteoporosis were compared, we observed that the former showed a lower exercise capacity (P=.023) and a higher BODE index (P=.002). CONCLUSIONS: The prevalence of a low BMD level was increased among male patients with a worse BODE index, especially due to a reduced exercise capacity.

RESUMO

INTRODUCTION: Bronchiolitis obliterans (BO) occurring after allogeneic bone marrow transplant (ABMT) may be an expression of lung damage of multifactorial origins. At present, it is not a usual condition for lung transplant (LT), accounting for <1% of all indications in the international registry. We sought, to describe the clinical features and outcomes of patients undergoing LT for BO after ABMT in our group. PATIENTS AND METHODS: We undertook a cross-sectional study of patients with an indication for LT due to BO after ABMT from the beginning of our program. We recorded the type of transplant, patient age, clinical course, functional outcome, and survival. RESULTS: Among 313 LT, 13 cases (4.2%) were due to BO, including 3 after ABMT (0.96%). ABMT was indicated after bone marrow aplasia in 2 cases and acute myeloid leukemia in the other patient. The patients were 2 men (both 35 years old) and 1 woman, aged 25 years. All subjects received double elective LT at 24, 20, and 9 years post ABMT. At the time of LT, all displayed severe obstructive ventilatory defects with a forced expiratory volume in 1 second (FEV1)<30% and partial respiratory insufficiency. The initial immunosuppression was cyclosporine, mycophenolate mofetil, and steroids in all cases. Two of the subjects required changes in the immunosuppressive regimen: 1 due to chronic graft rejection with subsequent functional recovery and the other due to hematologic and neurologic toxicity. After 96, 37, and 9 months, all the patients were alive with baseline dyspnea of functional class 0 and a FEV1 of about 68%. CONCLUSION: LT is an effective therapy in terms of lung function and survival for patients with respiratory failure secondary to the development of BO after ABMT.

RESUMO

Objetivos: determinar si el síndrome de apneas-hipopneas del sueño (SAHS) incrementa las cifras de catecolaminas y a través de este mecanismo puede alterar el perfil lipídico. Pacientes y métodos: estudio prospectivo, grupo control y muestreo consecutivo de sujetos con sospecha de SAHS. Fueron excluidos aquellos con enfermedad grave de órgano o ingesta de fármacos con efecto sobre la actividad simpática y/o perfil lipídico. Según el índice de apneas-hipopneas (IAH) obtenido en la polisomnografía, los sujetos se asignaron al grupo clínico (IAH >5) o al grupo control (IAH <5). En ambos se compararon las cifras de colesterol total, HDL-c, triglicéridos y noradrenalina urinaria. Resultados: Fueron incluidos 33 en el grupo clínico y 16 en el control sin existir diferencias en edad, género e índice de masa corporal (IMC). En el grupo clínico, la noradrenalina en orina y colesterol total se elevaron significativamente mientras que disminuyeron las del HDL-colesterol. Se observó una correlación significativa entre los valores de la saturación periférica de O2 (SapO2) y la noradrenalina urinaria, aunque la variabilidad de ésta sólo se asoció independientemente con el índice de desaturación y el IMC. También se detectó correlación significativa entre la noradrenalina urinaria y colesterol total, HDL-c y triglicéridos, sin embargo esta correlación desapareció al ajustar por edad, género e IMC. Conclusiones: el SAHS aumenta la actividad simpática nocturna y el índice de desaturación es el factor de mayor influencia. En los pacientes con SAHS se incrementan significativamente las cifras séricas de colesterol total mientras descienden las del HDL-c, aunque estos resultados no fueron explicados de forma independiente por el aumento en la actividad simpática (AU)
