Efectos adversos de la acumulación renal de hemoproteínas. Nuevas herramientas terapéuticas / Adverse effects of the renal accumulation of haem proteins. Novel therapeutic approaches

La hemoglobina y la mioglobina son hemoproteínas que juegan un papel fundamental en el organismo ya que participan en el transporte de oxígeno. Sin embargo, debido a su estructura química, estas moléculas pueden ejercer efectos deletéreos cuando se liberan al torrente sanguíneo de forma masiva, como sucede en determinadas condiciones patológicas asociadas a rabdomiólisis o hemólisis intravascular. Una vez en el plasma, estas hemoproteínas se pueden filtrar y acumular en el riñón, donde resultan citotóxicas, principalmente para el epitelio tubular, e inducen fracaso renal agudo y enfermedad renal crónica. En la presente revisión analizaremos los distintos contextos patológicos que provocan la acumulación renal de estas hemoproteínas, su relación con la pérdida de función renal a corto y largo plazo, los mecanismos fisiopatólogicos responsables de sus efectos adversos y los sistemas de defensa que contrarrestan tales acciones. Por último, describiremos los distintos tratamientos utilizados actualmente y mostraremos nuevas opciones terapéuticas basadas en la identificación de nuevas dianas celulares y moleculares, prestando especial atención a los diversos ensayos clínicos que se encuentran en marcha en la actualidad (AU)

Haemoglobin and myoglobin are haem proteins that play a key role as they help transport oxygen around the body. However, because of their chemical structure, these molecules can exert harmful effects when they are released massively into the bloodstream, as reported in certain pathological conditions associated with rhabdomyolysis or intravascular haemolysis. Once in the plasma, these haem proteins can be filtered and can accumulate in the kidney, where they become cytotoxic, particularly for the tubular epithelium, inducing acute kidney failure and chronic kidney disease. In this review, we will analyse the different pathological contexts that lead to the renal accumulation of these haem proteins, their relation to both acute and chronic loss of renal function, the pathophysiological mechanisms that cause adverse effects and the defence systems that counteract such actions. Finally, we will describe the different treatments currently used and present new therapeutic options based on the identification of new cellular and molecular targets, with particular emphasis on the numerous clinical trials that are currently ongoing (AU)

Prevenção e tratamento de equimose, edema e fibrose no pré, trans e pós-operatório de cirurgias plásticas / Prevention and treatment of ecchymosis, edema, and fibrosis in the pre-, trans-, and postoperative periods of plastic surgery

Introdução: A fibrose, o edema intenso e a equimose são as intercorrências que representam um grande desafio ao fisioterapeuta dermatofuncional no pós-operatório de cirurgia plástica de lipoaspiração e abdominoplastia. O objetivo é propor uma abordagem inédita desde o pré, trans e pós-operatório para prevenir e minimizar as fibroses, edema intenso e equimoses, acelerando a recuperação do paciente e reduzindo o número de sessões. Método: Ensaio clínico controlado, composto por 20 pacientes do sexo feminino, com idade entre 18 e 56 anos, divididos em dois grupos: 10 no grupo controle (GC) e 10 no grupo experimental (GE), que apresentavam indicação cirúrgica de abdominoplastia ou lipoaspiração abdominal, associadas ou não, e que se encontravam com no mínimo 7 dias de pré-operatório. Os dois grupos foram avaliados no pré-operatório. O GC recebeu atendimento somente a partir do 4º dia de pós-operatório, enquanto que o grupo GE recebeu atendimento durante o pré, trans e pós-operatório. Resultados: O grupo experimental apresentou uma média menor do número de sessões (p = 0,0032), perimetria menor no 4º dia de pós-operatório (p < 0,05) nos pontos antômicos: sulco inframamário e crista ilíaca, média menor na resolução da fibrose (p = 0,0058) e média menor na resolução da equimose (p = 0,0002) em relação ao grupo controle. Conclusão: Pode-se concluir com este estudo inédito que o tratamento no pré, trans e pós-operatório reduz o edema, a formação de equimose e principalmente a formação de fibrose no pós-operatório. Também diminui o número de sessões fisioterapêuticas e acelera o restabelecimento do paciente no pós-operatório das cirurgias abdominais.

Introduction: Fibrosis, intense edema, and ecchymosis are complications that represent a great challenge to dermatofunctional physiotherapists in the postoperative period of liposuction and abdominoplasty. Here we aimed to propose a new approach in the pre-, trans-, and postoperative periods to prevent and minimize fibrosis, intense edema, and ecchymosis, thereby expediting the patient's recovery and reducing the number of required physiotherapy sessions. Method: This controlled clinical trial included 20 female patients aged 18-56 years who were divided into the control group (CG; n = 10) and experimental group (EG; n = 10). All were scheduled to undergo abdominoplasty or abdominal liposuction at least 7 days after enrollment. The two groups were evaluated preoperatively. The CG received care only from the 4th postoperative day, while the EG received care during the pre-, trans-, and postoperative periods. Results: The EG required fewer mean physiotherapy sessions (p = 0.0032) and had lower perimetry values on the 4th postoperative day (p < 0.05) in the inframammary groove and iliac crest, lower mean resolution of fibrosis (p = 0.0058), and lower mean resolution of ecchymosis (p = 0.0002) compared to the CG. Conclusion: The findings of this unprecedented study indicate that treatment in the pre-, trans-, and postoperative periods reduces edema, ecchymosis, and fibrosis formation in the postoperative period. It also decreases the number of required physiotherapy sessions and accelerates patient recovery from abdominal plastic surgery.

Avaliação da Função do Ventrículo Direito e Fibrose Miocárdica por Ressonância Magnética Cardíaca em Pacientes com Infarto do Miocárdio da Parede Inferior / Assessment of Right Ventricle Function and Myocardial Fibrosis by Cardiovascular Magnetic Resonance in Patients with Inferior Wall Myocardial Infarction

Fundamentos: Disfunção do ventrículo direito (VD) é observada em 30-50% dos pacientes com infarto do miocárdio na parede inferior (IM-I) e é fator preditor de mortalidade precoce. A fibrose miocárdica está associada com disfunção ventricular progressiva e prognóstico grave. Nesses pacientes, a ressonância magnética cardíaca (RMC) é um importante método de estratificação de risco. Objetivos: Avaliar a associação entre disfunção do VD e fibrose miocárdica em pacientes com IM-I por RMC. Métodos: Estudo coorte realizado em um centro de cardiologia de referência. Quarenta indivíduos com IM-I foram incluídos no estudo. RMC foi realizada durante a internação para estimar função do VD e quantificar fibrose miocárdica pela técnica de realce tardio com gadolínio (TRT). Os pacientes foram estratificados quanto à função ventricular, e características clínicas foram comparadas entre os grupos. Resultados: Quarenta pacientes foram incluídos no estudo, 75% eram homens e 43% idosos (idade ≥ 60 anos). Entre os fatores de risco cardiovasculares, hipertensão (45%) e tabagismo (33%) foram os mais prevalentes. A disfunção do VD estava presente em 33% dos pacientes. A massa de fibrose média foi 22 ± 12g nos pacientes com disfunção do VD e 15 ± 8 g nos pacientes com função ventricular preservada (p = 0,051). Conclusões: Os resultados deste estudo indicam uma possível associação entre disfunção do VD e fibrose miocárdica nos pacientes com IM-I. No entanto, outros estudos envolvendo um maior número de pacientes são necessários para confirmar nossos achados

Background: Right ventricular dysfunction (RVD) can be found in 30-50% of patients with inferior wall myocardial infarction (I-MI) and predicts early mortality. Myocardial fibrosis is associated with progressive ventricular dysfunction and severe prognosis. In these patients, cardiovascular magnetic resonance (CMR) is an important risk stratification method. Objectives: This study sought to evaluate the association between RVD and myocardial fibrosis in patients with I-MI, using CMR. Methods: Cohort study conducted in a prominent center of cardiology. Forty individuals with I-MI were included in the study. CMR was performed during hospitalization to estimate parameters of right ventricle function and to quantify myocardial fibrosis through late gadolinium enhancement (LGE) technique. Patients were stratified by ventricular function, and clinical characteristics were compared between study groups. Results: Forty patients were included in the study, 75% were male and 43% elderly (age ≥ 60 years). Hypertension (45%) and smoking (33%) were the most prevalent cardiovascular risk factors. RVD was found in 33% of patients. Mean fibrosis mass was 22 ± 12 g in patients with RVD compared with 15 ± 8 g in patients with preserved ventricular function (p = 0.051). Conclusions: The findings of our study indicate a possible association between RVD and myocardial fibrosis in patients with I-MI. However, further studies with larger series are needed to confirm our findings

Efecto del plasma rico en plaquetas y/o factores de crecimiento sobre la regeneración y el dolor crónico asociado a discopatía intervertebral. Revisión sistemática / Effect of platelet rich plasma and growth factors on the regeneration and chronic pain associated with intervertebral disc disease. Systematic review

Objetivo: Determinar el efecto del plasma rico en plaquetas y factores de crecimiento sobre la regeneración y la reducción del dolor en discopatía degenerativa. Material y método: Revisión sistemática de la literatura. Se siguió las recomendaciones de la colaboración Cochrane expuestas en el Cochrane Hand book for Systematic Reviews of interventions. Se incluyeron ensayos clínicos aleatorizados fases preclínicas y clínicas donde evaluaban el efecto del plasma rico en plaquetas o factores de crecimiento sobre la discopatía degenerativa entre el 1 de septiembre de 2013 y el 30 de septiembre de 2014, publicados en PubMed, MEDLINE y LILACS. Resultados: En la búsqueda inicial se identificaron 11 artículos, de los cuales 3 cumplieron los criterios de selección determinados para esta revisión. Se realizó estrategia de búsqueda donde se revisaron las citas relacionadas de los tres artículos principales. De éstos, sólo 6 cumplieron los criterios de selección. Se incluyeron dos artículos más que arrojó la búsqueda en google académico, quedando un total de 10 estudios para el análisis final. En esta revisión, nosotros incluimos en la búsqueda de no sólo aquellos estudios realizados in vitro, sino además aquellos estudios en modelos murinos y estudio realizado en humanos. De estos estudios, la mayor parte de ellos fueron realizados in vitro (6), en modelos animales (2) y en humanos (2). En este estudio se seleccionaron sólo aquellos estudios donde fue evaluado el PRP y/o los factores de crecimiento sobre las células o tejidos del disco intervertebral. Para poder conocer el efecto que estas sustancias, tienen que ser evaluadas en estudios tanto preclínicos como clínicos. Todos los estudios analizados coincidieron sobre el efecto antiinflamatorio, reparador, proliferador e incluso en la mejoría del dolor de la discopatía vertebral. Conclusiones: Los resultados de los estudios muestra el efecto antiinflamatorio, reparador, proliferador e incluso en la mejoría del dolor de la discopatía vertebral. En ninguno de ellos se mencionó si este aumento de la síntesis de la matriz conllevaría a una mayor fibrosis del tejido y mayor deterioro, por lo que los estudios en animales o en humanos deberían enfocarse a evaluar un seguimiento mayor para poder evaluar los efectos tardíos de la terapia. Por lo tanto, podemos concluir que los puntos de enfoque de la investigación actual debe apuntar hacia entender más el mecanismo de la degeneración discal conjuntamente con los beneficios del PRP en tratarla (AU)

Objective: To determine the effect of platelet-rich plasma and growth factors on regeneration and reduction of pain in degenerative disc disease. Methods: Systematic review of the literature. The recommendations of the Cochrane Collaboration Cochrane outlined in the Handbook for Systematic Reviews of interventions was followed; randomized clinical trials preclinical and clinical phases which evaluated the effect of platelet-rich plasma or growth factors for degenerative disc disease between september 1/2013 to september 30/2014, published in PubMed, MEDLINE and LILACS were included. Results: The initial search 11 items of which 3 met the selection criteria determined for this review were identified. Search strategy where citations related to the three main articles were reviewed was conducted. Of these only 6 met the selection criteria. Threw two articles in academic google search, leaving a total of 10 studies were included in the final analysis. In this review we include in the search not only those studies in vitro but also those studies in murine models and human study. From these studies, most of them were done in vitro (6), in animal models (2) and in humans (2). In those studies where this study was evaluated PRP and growth factors on cells or tissues of the intervertebral disc is selected alone. To know the effect these substances have to be evaluated in both preclinical and clinical studies. All studies reviewed agreed on the anti-inflammatory effect, repair, and even proliferator improvement in pain, vertebral discopathy. Conclusions: The results of studies showing the anti-inflammatory effect, repair, and even proliferator improvement in pain, vertebral discopathy. None of them mention whether this increased matrix synthesis would lead to greater tissue fibrosis and further deterioration, so that studies in animals or humans should focus on evaluating increased monitoring, to assess late effects of therapy. Therefore we can conclude that the focus points of the present investigation should point to more understand the mechanism of disc degeneration together with the benefits of PRP to treat it (AU)

Comparison of the Effects of Telbivudine and Entecavir Treatment on Estimated Glomerular Filtration Rate in Patients with Chronic Hepatitis B

BACKGROUND/AIMS: The aim of this study was to evaluate the estimated glomerular filtration rate (eGFR) during telbivudine (LdT) versus entecavir (ETV) treatment in chronic hepatitis B (CHB) patients with underlying comorbidities such as diabetes mellitus (DM), hypertension, and cirrhosis. METHODS: From 2010 to 2012, 116 CHB patients treated with LdT and 578 treated with ETV were compared in this real-practice cohort. The mean changes in eGFR (Modification of Diet in Renal Disease [MDRD] formula) from baseline to months 6, 12, and 18 were analyzed using a linear mixed model. RESULTS: In LdT-treated patients, the mean eGFR increased by 7.6% at month 18 compared with the eGFR at baseline (MDRD formula in mL/min/1.73 m2). However, in ETV-treated patients, the mean eGFR decreased by 4.1% at month 18 compared with the eGFR at baseline. In the LdT-treated patients with DM, hypertension, cirrhosis or low eGFR <90 mL/min/1.73 m2, the mean eGFR showed a steady improvement, whereas the mean eGFR was reduced in the same subgroups of ETV-treated patients. CONCLUSIONS: The eGFR gradually increased over time during LdT treatment, especially in patients with mild abnormal eGFR at baseline, and in those with DM, hypertension, and cirrhosis, whereas a reduction in eGFR was seen with ETV treatment.

Últimos avances en pancreatitis crónica / Latest advances in chronic pancreatitis

Los avances más recientes con impacto en la práctica clínica de los pacientes con pancreatitis crónica se centran en el diagnóstico precoz de la enfermedad, la predicción del grado de fibrosis del páncreas, la evaluación de los pacientes con elevación asintomática de los valores séricos de enzimas pancreáticas, el tratamiento quirúrgico y farmacológico del dolor y el conocimiento de la historia natural de la pancreatitis autoinmune. En pacientes con hallazgos ecoendoscópicos indeterminados para pancreatitis crónica, la repetición de la ecoendoscopia en el seguimiento permite confirmar o excluir el diagnóstico. El hábito tabáquico, las reagudizaciones, los resultados de las pruebas funcionales pancreáticas y los hallazgos ecoendoscópicos permiten predecir el grado de fibrosis en pancreatitis crónica. En el tratamiento del dolor, la administración oral de antioxidantes parece ser eficaz, aunque queda por demostrar su combinación y dosis óptima. El desarrollo de sobrecrecimiento bacteriano es muy frecuente en pacientes con pancreatitis crónica, aunque su impacto sobre los síntomas es desconocido. Por último, la pancreatitis autoinmune recidiva en alrededor de la mitad de los pacientes y lo hace habitualmente en los primeros 2 años de seguimiento, sin diferencias entre tipos 1 y 2

This article summarizes some of the recent and clinically relevant advances in chronic pancreatitis. These advances mainly concern the early diagnosis of the disease, the prediction of the fibrosis degree of the gland, the evaluation of patients with asymptomatic hyperenzimemia, the medical and surgical treatment of abdominal pain and the knowledge of the natural history of the autoimmune pancreatitis. In patients with indetermined EUS findings of chronic pancreatitis, a new endoscopic ultrasound examination in the follow-up is of help to confirm or to exclude the disease. Smoking, number of relapses, results of pancreatic function tests and EUS findings allow predicting the degree of pancreatic fibrosis in patients with chronic pancreatitis. Antioxidant therapy has shown to be effective in reducing pain secondary to chronic pancreatitis, although the type and optimal dose of antioxidants remains to be elucidated. Development of intestinal bacterial overgrowth is frequent in patients with chronic pancreatitis, but its impact on symptoms is unknown and deserves further investigations. Finally, autoimmune pancreatitis relapses in about half of the patients with either type 1 or type 2 disease; relapses frequently occur within the first two years of follow-up

Complicación vascular en abordaje posterior de cirugía lumbar. Caso clínico / Vascular complication during posterior spine surgery. Clinical case

Presentamos una lesión vascular en un varón intervenido mediante discectomía L5-S1, que volvió a consulta al año de la cirugía por una nueva lumbociatalgia con imagen de fibrosis en RMN y se le realizó una artrodesis L5-S1. Durante el tiempo de discectomía y preparación del espacio se identificó sangrado arterial. Ante el deterioro general, se procedió a efectuar una laparotomía media, encontrando un hematoma retroperitoneal y lesión arterial hipogástrica derecha por laceración. La lesión de la aorta o de sus ramas durante la discectomía es más frecuente en reintervenciones, precisando su detección y reparación inmediatas (AU)

We present a case of a male who underwent a right L5/S1 discectomy. He returned to his work after three months. A year after the patient consulted again for sciatic pain and MRI showed mild epidural fibrosis. He underwent a new surgery and during the discectomy step an arterial bleeding was identifacated. Given the general deterioration, the vascular surgeon proceeds to midline laparotomy, aortic clamping, vascular exploration with an important retroperitoneal hematoma and right hypogastric artery injury. Vascular injuries during the time of discectomy are more frequent reported in reoperations. Once this occurs, detection and immediate repair are prior (AU)

Nutrição funcional no pós-operatório de cirurgia plástica: enfoque na prevenção de seroma e fibrose / Functional nutrition in postoperative plastic surgery: focus on seroma and fibrosis prevention

INTRODUÇÃO: Com base na grande variedade de possíveis sequelas e intercorrências de cirurgias estéticas e no papel da nutrição no processo de recuperação dessas, percebe-se a necessidade de práticas terapêuticas que garantam eficácia do resultado estético final. MÉTODO: O presente estudo caracteriza-se como uma revisão não sistemática que associou possíveis nutrientes, compostos bioativos e fitoterápicos que previnam ou amenizem seroma e fibrose no pós operatório. Para tanto, foram utilizados artigos de revistas científicas do meio eletrônico, legislações nacionais e livros didáticos, publicados entre os anos de 2002 e 2012. RESULTADOS: Demonstrou-se que as principais causas de seroma e fibrose são cicatrização alterada, inflamação, estresse oxidativo e edema. Dessa forma, foi elaborado um guia prático com os nutrientes, compostos bioativos e fitoterápicos que podem ser utilizados a fim de prevenir, controlar ou amenizar as complicações no pós-cirúrgico de procedimentos estéticos. CONCLUSÃO: Salientou-se que para o tratamento das condições abordadas é fundamental que haja um trabalho multiprofissional, enfatizando um acompanhamento médico, nutricional e fisioterápico que abranja as alterações conhecidas na fisiopatologia de seroma e fibrose.

INTRODUCTION: Based on the wide range of possible consequences and complications of plastic surgery and the role of nutrition in the recovery process of these, we see the need for therapeutic practices to ensure effectiveness of the final aesthetic result. METHOD: This study is characterized as a non-systematic review of the possible associated nutrients, bioactive compounds and herbal medicines to prevent seroma and fibrosis. Thus, we used scientific journal articles from electronic media, national laws and textbooks published between 2002 and 2012. RESULTS: We demonstrated that the main causes of seroma and fibrosis are changed healing, inflammation, oxidative stress and edema. Thus, we designed a practical guide with nutrients, bioactive compounds and herbal medicines that can be used to prevent, control or mitigate the complications after plastic surgery. CONCLUSION: It was emphasized that for the treatment of covered conditions is essential that there is a multidisciplinary approach, emphasizing a medical, nutritional and therapeutic monitoring covering the known changes in the pathophysiology of seroma and fibrosis.

Esprúe colágeno: no olvidemos el tejido conectivo en la evaluación de la diarrea crónica / Collagenous sprue: don’t forget connective tissue in chronic diarrhea evaluation

El esprúe colágeno es una patología infrecuente del intestino delgado caracterizada por atrofia de la mucosa y depósito excesivo de colágeno a nivel subepitelial. Su etiología es desconocida y su diagnóstico se realiza en base a la presencia tanto de un cuadro clínico compatible como de hallazgos anatomopatógicos sugestivos. Los pacientes suelen presentar diarrea crónica, malabsorción, deficiencias nutricionales graves y una marcada pérdida ponderal. Dentro del diagnóstico diferencial es mandatorio descartar enfermedad celiaca por su frecuente asociación a la misma. La dieta sin gluten es el primer escalón terapéutico, pero generalmente no es efectiva. Sin embargo, estudios recientes señalan altas tasas de éxito mediante el uso de inmunomoduladores. Presentamos el caso de un paciente con diarrea crónica y malabsorción grave diagnosticado de esprúe colágeno, sin respuesta a la dieta sin gluten, en el que el tratamiento con budesonida ha conseguido una excelente respuesta(AU)

Collagenous sprue is a rare disease of the small bowel characterized by mucosal atrophy and excessive subepithelial collagen deposition. The etiology remains unclear and the diagnosis is based upon patient’s clinical picture and anatomopathological findings. Clinically, collagenous sprue is characterized by persistent diarrhoea, severe malabsorption, multiple nutrient deficiencies and progressive weight loss. Differential diagnosis includes celiac disease, which is mandatory to rule out because of their frequent association. Gluten-free diet is the first therapeutic step, but it usually is not effective. However, recent studies show high success rates with immunomodulators, mainly corticosteroids. We report the case of a patient presenting with chronic diarrhea and severe malabsorption who was diagnosed with collagenous sprue, with no response to gluten free diet, but with excellent response to budesonida(AU)

Noninvasive predictors of nonalcoholic steatohepatitis in Korean patients with histologically proven nonalcoholic fatty liver disease

BACKGROUND/AIMS: The aims of this study were (1) to identify the useful clinical parameters of noninvasive approach for distinguishing nonalcoholic steatohepatitis (NASH) from nonalcoholic fatty liver disease (NAFLD), and (2) to determine whether the levels of the identified parameters are correlated with the severity of liver injury in patients with NASH. METHODS: One hundred and eight consecutive patients with biopsy-proven NAFLD (age, 39.8+/-13.5 years, mean+/-SD; males, 67.6%) were prospectively enrolled from 10 participating centers across Korea. RESULTS: According to the original criteria for NAFLD subtypes, 67 patients (62.0%) had NASH (defined as steatosis with hepatocellular ballooning and/or Mallory-Denk bodies or fibrosis > or =2). Among those with NAFLD subtype 3 or 4, none had an NAFLD histologic activity score (NAS) below 3 points, 40.3% had a score of 3 or 4 points, and 59.7% had a score >4 points. Fragmented cytokeratin-18 (CK-18) levels were positively correlated with NAS (r=0.401), as well as NAS components such as lobular inflammation (r=0.387) and ballooning (r=0.231). Fragmented CK-18 was also correlated with aspartate aminotransferase (r=0.609), alanine aminotransferase (r=0.588), serum ferritin (r=0.432), and the fibrosis stage (r=0.314). A fragmented CK-18 cutoff level of 235.5 U/L yielded sensitivity, specificity, and positive and negative predictive values of 69.0%, 64.9%, 75.5% (95% CI 62.4-85.1), and 57.1% (95% CI 42.2-70.9), respectively, for the diagnosis of NASH. CONCLUSIONS: Serum fragmented CK-18 levels can be used to distinguish between NASH and NAFL. Further evaluation is required to determine whether the combined measurement of serum CK-18 and ferritin levels improves the diagnostic performance of this distinction.

El manejo del priapismo isquémico agudo: una revisión actualizada / The management of the acute ischemic priapism: A state of the art review

Objetivo: Revisar la literatura actual sobre implantación de prótesis peneana temprana en pacientes con priapismo isquémico (PI) refractario. Adquisición de la evidencia: Se ha realizado una búsqueda sistemática de los términos «prótesis peneana», «priapismo», «impotencia», «fibrosis», «cilindros de prótesis reducidos» y «satisfacción del paciente» en bases de datos PubMed, EMBASE, Cochrane, SCOPUS y Science Citation Index. Síntesis de la evidencia: El daño del tejido cavernoso en PI está relacionado con el tiempo. Las medidas conservadoras y la aspiración con o sin instilación intracorpórea de agonistas alfa-adrenérgicos suelen tener éxito en las primeras etapas. La cirugía de derivación en pacientes sigue siendo discutible, ya que la falta de respuesta a la aspiración y a la instilación de agonistas alfa-adrenérgicos indica que es probable que ya hayan ocurrido cambios irreversibles en el músculo liso cavernoso. La implantación inmediata de la prótesis peneana en pacientes con PI refractario soluciona el episodio fálico, mantiene la rigidez a largo plazo necesaria para participar en relaciones sexuales penetrativas y previene el acortamiento peneano inevitable de otra manera. Aunque las tasas de complicaciones después de la implantación de la prótesis peneana en el priapismo agudo son mayores que en los casos virginales, son aún más bajas que después de la implantación en pacientes con fibrosis corporal grave debida al priapismo crónico. Independientemente de las tasas de complicaciones, la implantación de prótesis peneana en PI refractario debe ser preferida, ya que permite la preservación de la longitud del pene, que es uno de los principales factores que influyen en la satisfacción del paciente postoperatorio después de la cirugía

Objective: To review the current literature on early penile prosthesis implantation in patients with refractory ischemic priapism (IP). Acquisition of evidence: A systematic search for the terms "penile prosthesis", "priapism", "impotence", "fibrosis", "downsized prosthesis cylinders", and "patient satisfaction" has been carried out in PubMed, EMBASE, Cochrane, SCOPUS and Science Citation Index databases. Synthesis of evidence: Cavernosal tissue damage in IP is time related. Conservative measures and aspiration with or without intracorporeal instillation of alfa-adrenergic agonists are usually successful in the early stages. Shunt surgery in patients remains debatable, as the lack of response to aspiration and instillation of alfa-adrenergic agonists indicates that irreversible changes in the cavernosal smooth muscle are likely to have already occurred. Immediate penile prosthesis implantation in patients with refractory IP settles the priapic episode, maintains the long term rigidity necessary to engage in penetrative sexual intercourse and prevents the otherwise inevitable penile shortening. Although complication rates after penile prosthesis implantation in acute priapism are higher than in virgin cases, they are still lower than after implantation in patients with severe corporal fibrosis due to chronic priapism. Regardless of the complication rates, penile prosthesis implantation in refractory IP should be preferred as it allows the preservation of penile length, which is one of the main factors influencing postoperative patient's satisfaction following surgery
