Pancreatitis crónica: análisis de factores de progresión de la enfermedad / Chronic pancreatitis: analysis of disease progression factors

BACKGROUND: Alcohol and tobacco are important risk factors for chronic pancreatitis (CP). AIM: To analyze the effect of etiological factors such as tobacco and alcohol and pancreatic enzyme replacement therapy (PERT) in the progression of CP. MATERIAL AND METHODS: Patients with a diagnosis of CP were recruited and grouped according to variables such as tobacco, alcohol and PERT. They were followed for 18 months. Subsequently, different variables and analytical parameters involved in the progression of the disease were analyzed. RESULTS: A total of 50 patients diagnosed with CP were included. Of these, 28 patients underwent PERT, 39 were smokers and 33 were alcohol users. Compared with patients without PERT, those with PERT had a higher proportion of diabetes (64 and 32%, respectively), had a higher need for endoscopic treatment (25 and 0%, respectively) and a normal body mass index (71 and 27.3%, respectively. The smokers had higher calcium levels and increased lymphocytosis and leukocytosis. The alcohol consumption group had a higher mean age (p = 0.04) CONCLUSIONS: PERT may improve the nutritional status but does not reduce the need for endoscopic or surgical treatment. Smoking and alcohol consumption favored the progression of CP. Also, smoking induced a pro-inflammatory state.

Pancreatitis recurrente en pediatría: serie de casos / Recurrent pancreatitis in children: Case series

La pancreatitis recurrente (PR) ocurre en el 15-36 % de las pancreatitis agudas, en la edad pediátrica. Se realizó un estudio descriptivo y transversal, para determinar la etiología y la evolución en menores de 18 años con diagnóstico de PR entre 2008-2016 en el Hospital Garrahan. Se incluyeron 10 pacientes, el 90 % de sexo femenino. La mediana de edad fue de 11 años. La mediana del número de episodios fue de nueve. La ecografía abdominal y/o la colangioresonancia iniciales mostraron hallazgos patológicos en cuatro pacientes. De los seis pacientes con estudios iniciales normales, tres desarrollaron signos de pancreatitis crónica (PC), uno con estenosis del Wirsung sugestiva de pancreatitis autoinmune. El 40 % de los pacientes tuvo diagnóstico etiológico. En el seguimiento, tres pacientes con pancreatitis idiopática desarrollaron PC. Los factores genéticos podrían jugar un papel en los casos considerados idiopáticos.

Recurrent pancreatitis (RP) occurs in children between 15-35 % of the cases. To determine the etiology and outcome of RP in children a descriptive, cross-sectional cohort study was conducted in children under 18 years of age with RP seen at Hospital Garrahan between 2008-2016. Of 10 patients with RP, 90 % were girls. Median age of the diagnoses of RP was 11. Median number of episodes was 9. Initial abdominal ultrasonography and/or magnetic resonance cholangiopancreatography were abnormal in four patients. Of six patients with normal studies at onset, three developed signs of chronic pancreatitis (CP) and one stenosis of the duct of Wirsung suggestive of autoimmune pancreatitis. In 40 % of our patients, the etiology was determined. On follow-up, three patients with idiopathic pancreatitis developed CP. Genetic factors may play a role in patients considered to have idiopathic pancreatitis.

Descripción clínica y epidemiológica de pacientes con pancreatitis crónica en un hospital de alta complejidad en Cali, 2011 a 2017 / Clinical and epidemiological description of patients with chronic pancreatitis treated at a quaternary care hospital in Cali, 2011-2017

Resumen Introducción: la pancreatitis crónica (PC) es una inflamación progresiva del páncreas que puede llevar a su destrucción e insuficiencia irreversibles. Es una patología desafiante para el médico, debido a que establecer su diagnóstico puede tomar meses e incluso años, el seguimiento de pacientes suele ser problemático y el conocimiento sobre la clínica y epidemiología en Colombia es incompleto. Este estudio pretende hacer una descripción de pacientes con PC en un centro de referencia en gastroenterología de Cali, Colombia. Metodología: estudio de corte transversal de pacientes adultos con PC confirmada por criterios clínicos y radiológicos entre 2011 y 2017. Resultados: se incluyeron 36 pacientes con PC. La mayoría fueron hombres (72,2%) y la media de edad fue 56 (+ 15,1) años. El dolor abdominal crónico fue la presentación clínica más común (83,3%). Cerca de un cuarto de pacientes presentaba diabetes mellitus (22,2%). Se consideró etiología idiopática en 58,3%, alcohólica en el 11,0% y biliar en el 11,0%. La tomografía axial computarizada (TAC), resonancia magnética (RMN) y colangiopancreatografía por RMN fueron los métodos diagnósticos más usados (60,5%), con los que en su mayoría se visualizó atrofia (53,1%), dilatación de conductos (49,0%) y calcificaciones del páncreas (34,7%). Conclusión: los síntomas inespecíficos de la PC en fases iniciales y su largo curso clínico favorecen al subdiagnóstico de esta patología. Los resultados presentados pueden contribuir a la futura creación de escalas clínicas locales que orienten estudios radiológicos y genéticos tempranos, con el fin de lograr un diagnóstico oportuno y mejorar la calidad de vida de estos pacientes.

Abstract Introduction: Chronic pancreatitis (CP) is a progressive inflammation of the pancreas that can lead to irreversible damage and failure. This condition poses great challenges to physicians since its diagnosis can take months or even years. Patient follow-up is often problematic and knowledge about its clinical presentation and epidemiology in Colombia is scarce. This study aims to describe patients with CP treated at a gastroenterology reference center in Cali, Colombia. Methodology: Cross-sectional study in adult patients with CP confirmed based on clinical and radiological criteria between 2011 and 2017. Results: 36 patients with CP were included. The majority were men (72.2%), and the mean age was 56 (+15.1) years. Chronic abdominal pain was the most common clinical presentation (83.3%). About a quarter of patients had diabetes mellitus (22.2%). Etiology was idiopathic in 58.3%, alcoholic in 11.0%, and biliary in 11.0%. Computed tomography (CT), magnetic resonance imaging (MRI), and MRI cholangiopancreatography were the most commonly used diagnostic methods (60.5%), showing mostly atrophy (53.1%), duct dilation (49.0%), and pancreatic calcifications (34.7%). Conclusion: Nonspecific symptoms of CP in early stages and its long clinical course favor the underdiagnosis of this condition. The results presented may contribute to the future creation of local clinical scales that guide early radiological and genetic studies to achieve a timely diagnosis and improve the quality of life of these patients.

Alcoholic vs. non-alcoholic chronic pancreatitis: surgeons' perspective from a tertiary centre in india / Perspectiva dos cirurgiões sobre pancreatite crônica alcoólica vs. não-alcoólica de um centro terciário na índia

ABSTRACT Background: Although alcohol is the most common cause for chronic pancreatitis worldwide, idiopathic type is prevalent in India. Natural history and disease progression are different between these two groups. There is paucity of data comparing surgical outcome and quality of life in these patients. Aim: To evaluate clinical features, surgical outcome and quality of life between these two groups of patients. Method: All patients with chronic pancreatitis who underwent surgery were prospectively reviewed. Results: From 98 patients, 42 were alcoholic. Number of male and the mean age at the time of operation was significantly more in alcoholic patients. Smoking, preoperative hospital admission rate and the prevalence of local complications like inflammatory pancreatic head mass, biliary stricture and left sided portal hypertension were distinctly more common in alcoholic group. Frey procedure was required more commonly in alcoholic group. Mean postoperative hospital stay and overall postoperative complication rate were comparable between the two groups. Over a median follow up of 18 months there was significant improvement in quality of life and pain score in both the groups. Improvement of physical functioning score at follow-up was significantly more in alcoholic group but the requirement for analgesic medications were significantly more in alcoholic group. However, appetite loss was more perceived by non-alcoholic group. Conclusion: Alcoholic chronic pancreatitis presents with more local complications associated with chronic pancreatitis. Frey procedure is a safe and well accepted surgery in this group. Though they required more analgesic requirement in short term follow up, other aspects of quality of life are similar to non-alcoholic group.

RESUMO Racional: Embora o álcool seja a causa mais comum de pancreatite crônica em todo o mundo, a forma idiopática é prevalente na Índia. A história natural e a progressão da doença são diferentes entre esses dois grupos. Há escassez de dados comparando o resultado cirúrgico e a qualidade de vida entre eles. Objetivo: Avaliar as características clínicas, o resultado cirúrgico e a qualidade de vida entre esses dois grupos de pacientes. Método: Todos os pacientes com pancreatite crônica operados foram revisados ​​retrospectivamente. Resultados: Do total de 98 pacientes, 42 eram alcoolistas. O número de homens e a idade média no momento da operação foi significativamente maior nos alcoolistas. Tabagismo, taxa de internação pré-operatória e prevalência de complicações locais como massa inflamatória da cabeça do pâncreas, estenose biliar e hipertensão portal do lado esquerdo foram distintamente mais comuns no grupo de alcoolistas e o procedimento de Frey foi exigido mais comumente neste grupo. A média de internação pós-operatória e a taxa geral de complicações pós-operatórias foram comparáveis ​​entre os dois grupos. Ao longo de acompanhamento médio de 18 meses houve melhora significativa na qualidade de vida e pontuação de dor em ambos os grupos. A melhora no escore de funcionamento físico foi significativamente maior no grupo de alcoolistas, mas a necessidade de medicamentos analgésicos foi significativamente maior nos alcoolistas. No entanto, a perda de apetite foi mais percebida pelo grupo não alcoólico. Conclusão: A pancreatite crônica alcoólica se apresenta com mais complicações locais associadas à pancreatite crônica. O procedimento de Frey é operação segura e bem aceita neste grupo. Embora exigissem mais necessidade de analgésicos no acompanhamento em curto prazo, outros aspectos da qualidade de vida são semelhantes ao grupo não alcoólico.

Pseudoaneurisma de aorta abdominal como complicação de pancreatite crônica: relato de caso / Abdominal aortic pseudoaneurysm as a complication of chronic pancreatitis: case report

A pancreatite crônica é uma enfermidade associada a diversas complicações vasculares, como pseudocisto hemorrágico, trombose do sistema venoso portal e formações varicosas e pseudoaneurismáticas. O pseudoaneurisma de aorta abdominal secundário à pancreatite crônica é uma complicação rara, de difícil suspeição clínica, que requer tratamento complexo. A fisiopatologia dessa condição envolve a corrosão enzimática tecidual após a liberação e ativação de enzimas exócrinas proteolíticas das células acinares do pâncreas. O presente estudo relata o caso de um paciente de 52 anos, etilista crônico, internado com dor abdominal difusa, cuja propedêutica revelou se tratar de um pseudoaneurisma em aorta infrarrenal. Optou-se pelo tratamento cirúrgico convencional, levando-se em consideração a idade, as condições clínicas do paciente e a disponibilidade de endopróteses compatíveis com o diâmetro da aorta

Chronic pancreatitis can be complicated by several vascular disorders, such as bleeding pseudocysts, thrombosis of the venous portal system, varicosities, and pseudoaneurysms. Pseudoaneurysm of the abdominal aorta secondary to chronic pancreatitis is a rare complication. It is a challenging clinical situation, demanding a high degree of clinical suspicion, and requires complex therapeutic procedures. The pathophysiology of this condition involves interstitial liberation and activation of enzymes from the exocrine pancreatic glands and subsequent digestion of the surrounding tissues. In the present case report, we describe a 52-year-old patient complaining of diffuse abdominal pains. Clinical investigation revealed chronic alcoholism and imaging examinations showed a pseudoaneurysm of the infrarenal aorta. We decided to perform conventional surgical treatment after considering the patient's age and clinical status and the endoprostheses available at our hospital with diameters compatible with the patient's aorta

Una actualización de pancreatitis crónica: artículo de revisión / Update on chronic pancreatitis: review article

La pancreatitis crónica es una enfermedad fibro-inflamatoria progresiva del páncreas caracterizada por la fibrosis irreversible de la glándula con el eventual fallo de las funciones exocrinas y endocrinas. Las características distintivas de la enfermedad son el dolor abdominal, la malabsorción, la desnutrición, la diabetes mellitus y las calcificaciones pancreáticas. En muchos pacientes el origen de esta enfermedad se debe a una compleja mezcla de factores ambientales (por ejemplo, alcohol, cigarrillos y productos químicos en el trabajo), factores genéticos y en algunos casos origen hereditario o autoinmune. El manejo incluye enfoques médico, endoscópico y quirúrgico con la necesidad de la interacción entre diversas especialidades para dar un enfoque multidisciplinario coordinado. Esta revisión ofrece una visión general de los estudios recientes resumiendo la epidemiología, etiología, fisiopatología, manifestaciones clínicas, diagnóstico y tratamiento de la enfermedad.

Chronic pancreatitis is a progressive fibro-inflammatory disease of the pancreas characterized by irreversible fibrosis of the gland with eventual failure of exocrine and endocrine functions and hallmark features of abdominal pain, malabsorption, malnutrition, diabetes mellitus and pancreatic calcifications. In many patients this disease results from a complex mix of environmental (eg, alcohol, cigarettes, and occupational chemicals), genetic factors and a few patients with hereditary or autoimmune disease. The management includes medical, endoscopic and surgical approaches with the need for interaction between various specialties, calling for a concerted multidisciplinary approach. This review provides the reader with a comprehensive overview of the studies summarizing the epidemiology, etiology, physiopatology, clinical manifestation, diagnosis and treatments of the disease.

Pancreatitis, genes y autotrasplante de islotes: actualizaciones y nuevos horizontes / Pancreatitis, genes and islet cells auto transplant: updates and new horizons

La pancreatitis es una inflamación del páncreas que puede progresar de una presentación aguda, a una presentación aguda recurrente y eventualmente a pancreatitis crónica, caracterizada por cambios morfológicos y formación de cicatriz los cuales son irreversibles. La entidad conocida como pancreatitis hereditaria ha sido reconocida en la literatura por años y ciertamente el hallazgo del gen PRSS1 en 1996 marcó el inicio de una era de descubrimientos genéticos asociados a dicha enfermedad. Desde entonces, múltiples genes han sido descritos como causa de pancreatitis hereditaria o modificadores de la enfermedad, entre los que se destacan el PRSS1, SPINK1, CFTR, CASR, CTRC, CLDN2 y CPA1 entre otros. La selección de pacientes a la que se le va a practicar los estudios genéticos correspondientes debe ser guiada por las recomendaciones de los expertos y debe cumplir con los criterios correspondientes. El tratamiento, una vez hecho el diagnóstico, debe ser adaptado en base a las necesidades particulares de cada paciente. Ciertamente, el advenimiento de la pancreatectomía total con auto trasplante, cuyo principal objetivo es aliviar el dolor ocasionado por la pancreatitis crónica a la vez que se reduce la severidad de la diabetes inducida por la pancreatectomía, es una alternativa atractiva en el tratamiento y manejo de pacientes con diagnóstico de pancreatitis hereditaria. Sin embargo, estrictos criterios y un manejo interdisciplinario son esenciales ya que éste es un procedimiento irreversible y tiene consecuencias médicas por el resto de la vida que todo paciente tiene que conocer y que a su vez, el equipo médico debe saber identificar y tratar a tiempo. Sin embargo, existen muchas áreas potenciales en este campo para investigaciones que sean mayores, mejores y a la vanguardia para lograr un mejor entendimiento y desarrollar potenciales curas para esta enfermedad

Pancreatitis is an inflammation of the pancreas that can progress from an acute presentation to an acute recurring presentation and eventually to chronic pancreatitis, which is characterized by irreversible morphological changes and scarring of the pancreas. The entity known as hereditary pancreatitis has been recognized in the literature for years and certainly the discovery of the PRSS1 gene in 1996 marked the beginning of a new era of genetic discoveries associated with the disease. Since then, multiple genes have been described as the causing agents of pancreatitis or disease modifiers, some of the most important ones being the PRSS1, SPINK1, CFTR, CASR, CTRC, CLDN2, and CPA1. The patient selection process for genetic testing should be guided by the current experts' recommendations and should meet specific corresponding criteria. Once the diagnosis has been made, treatment should be tailored to each patient's particular needs. Certainly, the advent of the total pancreatectomy with auto islet cell transplantation, which has the main goal to improve the pain caused by the chronic pancreatitis and simultaneously reduce the severity of the pancreatectomy induced diabetes, is an attractive alternative in the treatment and management of patient with a diagnosis of hereditary pancreatitis. However, strict criteria and an interdisciplinary management are essential since this surgery is irreversible and carries lifetime health consequences that all patients must be aware of and the medical team must be able to early recognize these and treat accordingly. However, there are many potential areas in this field for more, better and forefront research to be developed aiming for a better understanding of the disease process and for the development of a cure

Resonancia magnética de la pancreatitis autoinmune: una revisión de la literatura / Magnetic resonance imaging of autoimmune pancreatitis: a review of literature

La pancreatitis autoinmune (PAI) es una forma distinta de pancreatitis crónica, que se caracteriza por un mecanismo patogénico autoinmune. Su frecuencia es levemente mayor en los pacientes de sexo masculino (60%) y la edad promedio de presentación oscila entre los 40 y 60 años, aunque el rango etario es mucho más amplio (de 14 a 80 años). Desde el punto de vista histológico, la PAI se presenta con un infiltrado inflamatorio denso, de extensión variable, que puede ser focal o comprometer difusamente todo el páncreas. Su presentación clínica en la mayoría de los casos es inespecífica: dolor abdominal leve y rara vez síntomas de pancreatitis aguda, pérdida de peso o ictericia. Varios estudios han descrito un compromiso multiorgánico por el proceso autoinmune, indicando la naturaleza sistémica de la enfermedad. En 2011 el Consenso Internacional de Criterios Diagnósticos de la Pancreatitis Autoinmune (ICDC, por sus siglas en inglés) establecieron las directrices o guías diagnósticas, estipulando que la resonancia magnética (RM) y la colangiopancreatografía por RM (CPRM) constituyen las técnicas diagnósticas cardinales. En este trabajo presentamos las características imagenológicas de la PAI, sus diagnósticos diferenciales y hallazgos en imágenes luego del tratamiento y seguimiento. Adicionalmente, comunicamos nuestra experiencia en esta enfermedad problemática y poco frecuente.

Autoimmune pancreatitis (AIP) is a distinct form of chronic pancreatitis caused by an autoimmune pathogenetic mechanism. It affects males (60%) slightly more frequently, and generally occurs between 40 to 60 years, although the possible range is much wider (14-80 years). Histologically AIP is characterised by the presence of a dense inflammatory infíltrate, with variable extensión. It can be focal or diffuse throughout the whole páncreas. Clinical presentation in most cases is non-specific, with patients presenting with mild abdominal pain, rarely, acute pancreatitis symptoms, weight loss, and jaundice. Several studies reported múltiple organ involvement due to the autoimmune process, suggesting a systemic nature of the disease. In 2011 the International Consensus Diagnostic Criteria for autoimmune pancreatitis (ICDC) defined the guidelines, and magnetic resonance imaging (MRI) and MR-cholangiopancreatography (MRCP) became the reference diagnostic technique in the diagnosis of the disease. This paper will review the imaging characteristics, the differential diagnosis, and the imaging features after treatment and follow up. Furthermore, our experience in this uncommon and challenging disease is reviewed.

Tratamiento endoscópico en la pancreatitis crónica: seguimiento a largo plazo / Endoscopic treatment in chronic pancreatitis: long-term results in 18 patients

Background: Intraductal stones, ductal abnormalities and pancreatic pseudocysts are part of chronic pancreatitis (CP). The goal of treatment is pain relief, resolution of local complications and relapse prevention. Endoscopic therapy (ET) can be considered in those who do not respond to medical treatment. Aim: To evaluate the indication, immediate and long-term results of ET in CP patients. Patients and Methods: Review of a database of patients with CP analyzing results of ET in 18 patients aged 16 to 60 years (13 males). Demographics, etiology, endoscopic technique, indication for treatment, pain relief, relapses and complications were recorded. Results: The etiology of CP was alcohol consumption in 5, idiopathic in 11, hereditary in one and autoimmune in one case. The follow-up period was 6 months to 14 years. Seven patients had diabetes mellitus type 3c and eight had moderate to severe exocrine pancreatic insufficiency. Pancreatic papillotomy was performed in all patients, with removal of some stones, without attempting a complete clearance of the pancreatic duct. In addition, a 7-10 French stent was placed in the main pancreatic duct in 15 patients with varying permanence (months to years). The stent was changed guided by recurrence of clinical symptoms. During the follow-up period, 10 patients remained asymptomatic and in three, pain or relapse were significantly reduced. Stenting failed in one patient for technical reasons. Two patients were operated. There were neither immediate nor late complications from ET. Conclusions: Long-lasting improvement of CP was observed in 13 of 18 patients treated with ET, without complications associated with the procedure.

Quiste de colédoco gigante / Giant choledochal cyst

La dilatación quística del colédoco es una entidad rara. Tiene mayor incidencia en los países orientales que en los occidentales y predomina en el sexo femenino. Se diagnostica habitualmente en la infancia y se han postulado varias hipótesis para su origen entre las que se destacan las anomalías en la unión biliopancreática. Se presenta el caso de una paciente de 19 años de edad con un quiste de colédoco tipo IV de Todani con varios años de evolución. Finalmente recibió, una derivación como tratamiento definitivo; la evolución fue inmediata y satisfactoria(AU)

Choledochal cysts are rare and has higher incidence rate in the Eastern countries than in the Western nations. It is predominant in females. It is regularly diagnosed in the childhood and several hypotheses have been formulated about their origin, being one of them the biliopancreatic junction anomalies. This is the case of a 19 years-old patient with a Todani´s type IV choledochal cyst with several years of progression. He was finally performed a shunt as definitive treatment and his recovery was immediate and satisfactory(AU)

Health at the dawn of development: the thought of Abraham Horwitz / A saúde na alvorada do desenvolvimento: o pensamento de Abraham Horwitz

The article explores the ideas of Pan American Health Organization director Abraham Horwitz on the relations between health and development at the time the Alliance for Progress was established, in 1961. Taking development discourse as a public philosophy of international cooperation, the discussion centers on how Horwitz worked to mediate between health and development. Horwitz endeavored to establish arguments that highlighted the importance of social policy, especially in health; he also strove to reach different audiences and drew connections between elements like health, illness, and labor productivity, without ignoring the humanistic considerations so dear to the public health tradition.

O artigo examina as ideias de Abraham Horwitz, diretor da Organização Pan-americana da Saúde, sobre as relações entre saúde e desenvolvimento, quando da celebração da Aliança para o Progresso, em 1961. Toma-se o discurso do desenvolvimento como a filosofia pública da cooperação internacional e discute-se a forma pela qual Horwitz propõe uma mediação entre saúde e desenvolvimento. Verifica-se que ele preocupou-se em estabelecer um cardápio de argumentos favoráveis à importância das políticas sociais, em particular da saúde, ampliando adesões em diferentes audiências, afirmando conexões entre saúde, adoecimento e produtividade do trabalho, sem prescindir de um sentido humanístico, caro à tradição sanitarista.

Frequência de tabagismo e das mutações N34S e P55S do gene Serine Protease Inhibitor Kazal-Type 1 (SPINK1) e da mutação R254W do gene Quimotripsina C (CTRC) em pacientes portadores de pancreatite crônica e em controle / Frequency of tabagism and N34S and P55S mutation of Serine Protease Inhibitor Kazal-Type 1 gene (SPINK1) and R254W mutation of Chymotrypsin C gene (CTRC) in patients with chronic pancreatitis and controls

A pancreatite crônica é uma desordem complexa, na qual a interação entre fatores ambientais e genéticos resulta na enfermidade. O presente estudo incluiu 148 pacientes com diagnóstico de pancreatite crônica, 110 etilistas crônicos e 297 controles sadios com o objetivo de investigar a frequência de tabagismo e das mutações N34S e P55S do gene SPINK1 e R254W do gene CTRC nesta população. Foi aplicado questionário presencial e realizada reação de sequenciamento para a pesquisa das mutações genéticas, após assinatura do Termo de Consentimento Livre e Esclarecido. Os portadores de pancreatite crônica possuíam etiologia alcoólica em 74% das vezes e idiopática em 26%. A pancreatite alcoólica apresentou-se de maneira distinta da pancreatite crônica idiopática, sendo que o primeiro grupo é composto por maior prevalência do gênero masculino (88,18% versus 34,21%), por maior média de idade (55,64 anos versus 45,20 anos), menor frequência de caucasianos (63,89% versus 84,21%), menor escolaridade (23,30% concluíram ensino médio ou superior versus 57,89%) e maior frequência de repercussões da doença, como diarréia (54,21% versus 24,24%), emagrecimento (56,07% versus 24,24%), diabete melito (57,94% versus 36,36%) e ocorrência de pseudocistos pancreáticos (31,78% versus 12,12%), repercussões estas que não foram acompanhadas de maior frequência de alterações morfológicas, como calcificações pancreáticas ou dilatação do ducto pancreático principal. A frequência de tabagismo foi significativamente maior em pacientes com pancreatite crônica alcoólica do que em etilistas sem pancreatite crônica, podendo ser considerado cofator de risco para o desenvolvimento da pancreatite crônica entre alcoolistas (p = 0,002); a frequência da mutação N34S do gene SPINK1 em pacientes com pancreatite crônica foi de 3,38%, maior do que a frequência de 0,49% encontrada nos grupos controle (p = 0,016); a frequência de 2,03% da mutação P55S do gene SPINK1 e a frequência de 0,67% da mutação...

Chronic pancreatitis is a complex disorder in which the interaction between environmental and genetic factors results in the disease. This study included 148 patients with chronic pancreatitis, 110 chronic alcoholics and 297 healthy controls in order to investigate the frequency of smoking and N34S and P55S mutation of SPINK1 gene and R254W of CTRC gene in this population. A questionnaire was applied and gene sequencing was done, after having the Informed Consent Statement. Those with chronic pancreatitis had alcoholic etiology in 74% of cases and idiopathic in 26%. Alcoholic pancreatitis presented in a distinct way of idiopathic chronic pancreatitis. The first group is composed of a higher prevalence of males (88.18% versus 34.21%), by higher mean age (55.64 years versus 45.20 years), lower frequency of Caucasians (63.89% versus 84.21%), lower education (23.30% completed secondary or higher education versus 57.89%) and worst impact from the disease such as diarrhea (54.21% versus 24.24%), weight loss (56.07% versus 24.24%), diabetes mellitus (57.94% versus 36.36%) and occurrence of pancreatic pseudocysts (31.78% versus 12 , 12%). These effects were not accompanied by increased frequency of morphological changes, such as pancreatic calcifications or dilation of the main pancreatic duct. The frequency of smoking was significantly higher in patients with alcoholic pancreatitis than in alcoholics without chronic pancreatitis, therefore tabagism may be considered as a cofactor for the development of chronic pancreatitis among alcoholics (p = 0.002); the frequency of N34S mutation of SPINK1 gene in patients with chronic pancreatitis was 3.38%, higher than the rate of 0.49% found in the control groups (p = 0.016); the frequency of 2.03% of the P55S mutation of SPINK1 gene and the frequency of 0.67% of the CTRC gene R254W mutation found in patients with chronic pancreatitis were not statistically different when compared to the frequencies of 0.49%...

Avaliação da frequência de doença osteometabólica entre portadores de pancreatite crônica alcoólica e sua correlação com os hábitos alimentares e a composição corporal / Frequency of osteometabolic disease among patients with alcoholic chronic pancreatitis and its correlation with eating habits and body composition

O tecido ósseo é extremamente complexo que, juntamente com a cartilagem, constitui o sistema esquelético. Tanto os ossos quanto a cartilagem são compostos por tecido metabolicamente ativo com duas funções básicas para o organismo, uma mecânica e outra bioquímica. O impacto do déficit calórico e da perda de peso pode reduzir a massa óssea e mudar a composição corpórea. Na pancreatite crônica alcoólica o paciente relata ingestão alcoólica por longo período, além da referência do alto consumo de cigarros e de uma alimentação deficiente. Os objetivos do presente estudo foram avaliar a frequência da doença osteometabólica, os hábitos alimentares, a frequência de deficiência de vitamina D assim como, se os achados de massa corpórea por densitometria de corpo total se relacionam à deficiência de massa óssea, em indivíduos portadores de pancreatite crônica de etiologia alcoólica. Foram avaliados três grupos de pacientes do sexo masculino com pancreatite crônica alcoólica. Foram divididos de acordo com o resultado da densitometria óssea: 5 pacientes no grupo da osteoporose, 26 no grupo da osteopenia e 8 no grupo normal. Todos os pacientes foram submetidos ao registro alimentar de três dias, mensuração de peso, altura, cintura e quadril, Índice de Massa Corpórea (IMC) e exames laboratoriais. A composição corpórea foi avaliada pela densitometria óssea por raios X de dupla energia (DXA) e por bioimpedância elétrica. 79% dos pacientes do sexo masculino com pancreatite crônica alcoólica tiveram densidade mineral óssea comprometida. Os pacientes que tinham vitamina D prescrita foram excluídos porém nos nossos resultados a maioria dos pacientes apresentavam níveis normais da vitamina. Em relação ao tabagismos, dos pacientes fumavam. Os pacientes com maior comprometimento ósseo eram mais magros,contudo, não houve diferença entre os pacientes de acordo com o IMC. Os pacientes classificados pelo DXA como normais eram mais jovens do que os pacientes com osteopenia e osteoporose....

The bone tissue is extremely complex, along with cartilage constitutes the skeletal system. Both bones as cartilage are composed of metabolically active tissue with two basic functions for the body, mechanical and biochemistry. The impact of the caloric deficit and weight loss can reduce bone mass and change body composition. In chronic alcoholic pancreatitis patients alcohol intake over a long period, in addition to reference the high consumption of cigarettes and poor nutrition. The objectives were to evaluate the frequency of osteometabolic disease, eating habits, the frequency of vitamin D deficiency and how the body mass found by total body densitometry relate to bone deficiency in individuals with chronic pancreatitis of alcoholic etiology . We evaluated three groups of male patients with chronic pancreatitis alcoholic. They were according to the results of bone densitometry. 5 in osteoporosis group, 26 in the osteopenia group and 8 in the normal group. All patients underwent three-day food record, measurements of weight, height, waist and hip, body mass index (BMI) and laboratory tests. The body composition was evaluated by densitometry by dual energy X-ray absorptiometry (DXA) and electrical bioimpedance. 79% of male patients with alcoholic chronic pancreatitis had compromised bone mineral density. Patients were prescribed vitamin D were excluded however results in the majority of patients had normal levels of the vitamin. Half of all patients smoking. Patients with higher bone involvement were thinner, there was no difference between patients according to BMI. Patients classified as normal by DXA were younger than patients with osteopenia and osteoporosis. In summary, osteoporosis and osteopenia are undervalued sources of morbidity in patients with chronic pancreatitis and necessary health management guidelines bone in this group of patients.

Comparison of fccal elastase 1 for exocrine panreatic insufficiency evaluationn between ex-alcoholics and chronic pancreatitis patietts / Comparação da elastase fecal 1 para avaliação de insuficiência pancreática exócrina entre ex-alcoólatras e pacientes com pancreatite crônica

Context Fecal elastase is a noninvasive test for pancreatic insufficiency diagnosis. Objectives Evaluate the usefulness of fecal elastase 1 for the indication of exocrine pancreatic insufficiency among former alcohol addicts and patients with chronic pancreatitis. Methods Forty-three patients with chronic pancreatitis and thirty-three asymptomatic former alcohol addicts entered the study. The levels of fecal elastase 1 were measured using a commercial kit. Pancreatic imaging findings were used to categorize the groups. Results The levels of fecal elastase 1 were significantly lower in the patients than in the former alcohol addicts and in the group with tissue calcifications, duct alterations, or atrophy. With a cutoff level of 100 μg/g, the sensitivity of fecal elastase 1 in chronic pancreatitis was 46.51% and its specificity was 87.88% with a positive predictive value of 83.33% and a negative predictive value of 55.77%. When patients were stratified according to the severity of their pancreatitis, the sensitivity was 6.25% for mild pancreatitis and 70.37% for marked pancreatitis. Conclusion Low level of fecal elastase 1 was associated with marked rather than mild chronic pancreatitis; however, it may be useful to indicate pancreatic exocrine insufficiency in asymptomatic former alcohol addicts. .

Contexto O teste de elastase fecal é um teste não invasivo para diagnosticar insuficiência pancreática. Objetivos Avaliar a utilidade da elastase fecal 1 como indicador de insuficiência pancreática entre ex alcoólatras e pacientes com pancreatite crônica. Métodos Quarenta e três pacientes com pancreatite crônica e 33 ex alcoólatras assintomáticos entraram no estudo. Os níveis de elastase fecal 1 foram medidos usando kit comercial. Os achados de imagem pancreática foram usados para categorizar os grupos. Resultados Os níveis de elastase fecal 1 foram significantemente menores nos pacientes que nos ex alcoólatras e no grupo com calcificações teciduais, alterações de ductos, ou atrofia. A sensibilidade da elastase fecal 1 na pancreatite crônica foi de 46,51% e a especificidade foi de 87,88%, com valor preditivo positivo de 83,33% e valor preditivo negativo de 55,77%. Quando os pacientes foram estratificados segundo a severidade da pancreatite, a sensibilidade foi de 6,25% para pancreatite crônica leve e 70,37% para pancreatite crônica severa. Conclusão Baixo nível de elastase fecal foi associado com pancreatite crônica severa mais do que com a leve; entretanto, pode ser útil para indicar insuficiência pancreática exócrina entre os ex alcoólatras. .

Manejo endoscópico de las complicaciones de la pancreatitis / Endoscopic management of the complications of pancreatitis

Tanto la pancreatitis aguda como crónica causan diferentes complicaciones que antes del advenimiento de la terapéutica endoscópica tenían que ser tratadas con cirugía convencional. El avance de la endoscopía intervencionista nos ha permitido acceder al páncreas y tratar estas complicaciones efectivamente y con menor morbilidad para nuestros pacientes. Aproximadamente el 90% de las pancreatitis aguda son edematosas, tienen una resolución clínica temprana y sin complicaciones. Los pacientes que son admitidos con pancreatitis necrotizante están predispuestos a tener diferentes tipos de complicaciones tanto locales como sistémicas particularmente si hay falla orgánica. Por otro lado la pancreatitis crónica es un proceso inflamatorio crónico del páncreas en donde se ha establecido la fibrosis de la glándula con posible disfunción exocrina y/o endocrina. El objetivo principal de la terapéutica endoscópica en la pancreatitis crónica es aliviar la obstrucción y disminuir la presión del conducto pancreático con la intención de aliviar el dolor abdominal. En esta revisión vamos a hablar acerca de las indicaciones y técnica endoscópica para tratar las diferentes complicaciones de la pancreatitis como, drenaje de pseudoquistes, necrosectomía pancreática, manejo del síndrome de conducto desconectado y terapia endoscópica en pancreatitis crónica.

Acute and chronic pancreatitis may lead to complications that prior the recent advancement of therapeutic endoscopy had to be treated with conventional surgery. The current techniques in interventional endoscopy allow us to access the pancreas and treat some of the complications in a minimally invasive way leading to less morbidity in our patients. Approximately 90% of acute pancreatitis episodes are edematous with early resolution of clinical symptoms and rarely leading to major complications. Patients with necrotizing pancreatitis are susceptible to local and systemic complications particularly in the setting of organ failure. On the other hand chronic pancreatitis is as a chronic inflammatory process that leads to fibrosis of the gland and in occasions to exocrine and/or endocrine insufficiency. The main objective of therapeutic endoscopy in chronic pancreatitis is to relief the obstruction and decreases the pressure in the pancreatic duct with the intention to alleviate abdominal pain. In this review we will address the indications and endoscopic techniques to treat the different complications of pancreatitis such as pseudo cyst drainage, walled off necrosis debridement, disconnected duct syndrome and different options for endoscopic therapy in chronic pancreatitis.

Insuficiência exócrina do pâncreas: etiologias / Exocrine pancreatic insufficiency: etiology

Insuficiência exócrina do pâncreas tem sido revisitada em vários compêndios médicos internacionais e suas novas etiologias avaliadas e reconfirmadas. Neste artigo abordamos as causas mais comuns e tradicionais, pancreatite crônica e fibrose cística, bem como as recentemente mais enfatizadas como doença celíaca e diabetes mellitus. Comentamos a clínica e o diagnóstico precoce e o tratamento com reposição enzimática

Pancreatic exocrine insufficiency has been broadly discussed in international medical literature. New aetiologies have been studied and reaffirmed. In this paper we describe common and traditional causes such as chronic pancreatitis and cystic fibrosis as well as the most recently emphasised celiac disease and diabetes. We also review clinical features, early diagnosis and pancreatic enzyme replacement therapy

Alterações cutâneas no Kwashiorkor: relato de caso de um homem adulto após cirurgia abdominal / Cutaneous manifestations of kwashiorkor: a case report of an adult man after abdominal surgery

Kwashiorkor é um tipo de desnutrição proteico-energética em que há deficiência dietética de proteína, embora a ingestão de calorias se mantenha adequada. As manifestações cutâneas incluem pele xerótica, com aspecto de esmalte descascado, típica coloração avermelhada a branco-acinzentada dos cabelos, o sinal da bandeira e edema mais evidente, nos membros inferiores e na face, dando aspecto de lua cheia. O presente artigo relata o caso de um paciente adulto, do sexo masculino, previamente submetido à duodenopancreatectomia para tratamento de pancreatite crônica associada ao pseudotumor em cabeça de pâncreas que evoluiu com alterações cutâneas de kwashiorkor após tuberculose pulmonar.

Kwashiorkor is a type of protein-energy malnutrition where diet protein deficit is found, in spite of appropriate caloric intake. Cutaneous manifestations include xerosis, with abnormally dry skin that has a flaking enamel paint aspect, a typical red to gray-white hair color, the "flag sign" and more evident edema in lower limbs and face, giving it a full moon appearance. This article reports a case of a male adult patient who had undergone Whipple surgery for treatment of chronic pancreatitis associated with pseudotumor of the pancreatic head that progressed to cutaneous manifestations of kwashiorkor after pulmonary tuberculosis.

Paniculite pancreática como a primeira manifestação de doença visceral: relato de caso / Pancreatic panniculitis as the first manifestation of visceral disease: case report

A paniculite pancreática, condição patológica rara, acomete 2-3 por cento dos pacientes com doença do pâncreas. Em 40 por cento dos casos, precede manifestações de doença pancreática. Relata-se caso de paciente feminina, 71 anos, surgimento há 1 mês de nódulos eritematosos nas pernas que evoluíram para ulceração e saída de conteúdo amarelado. Sem sintomas abdominais. A biópsia revelou macrófagos vacuolizados e necrose gordurosa representada por áreas anfofílicas, de material amorfo. Exame laboratorial e TAC demonstraram pancreatite crônica. Presume-se que a liberação de enzimas pancreáticas, tais como a tripsina, pode aumentar a permeabilidade da microcirculação e, então, a lípase e a amilase causariam a necrose de gordura subcutânea observada nas lesões. Na histologia, observam-se "células fantasmas" e paniculite septal de início e posteriormente lobular. O tratamento direciona-se a resolução da doença base.

Pancreatic panniculitis is a rare pathological condition affecting 2-3 percent of patients with pancreatic disease. In 40 percent of cases the condition precedes manifestations of pancreatic disease. We report the case of a 71-year-old female who presented with an erythematous tender node which had appeared one month previously, progressing to ulceration and yellowish exudation. No abdominal symptoms. Biopsy revealed fat necrosis and vacuolated macrophages represented by amorphous amphophilic areas. Laboratory examination and CT scan revealed chronic pancreatitis. It is assumed that release of pancreatic enzymes such as trypsin may enhance the permeability of the microcirculation leading to lipase and amylase causing the subcutaneous fat necrosis observed in the lesions. Histology showed "ghost cells" and, firstly, septal panniculitis, followed later by lobular panniculitis. Treatment focused on resolution of the underlying pancreatic disease.

Pancreatitis crónica: nuevas terapias / Chronic pancreatitis: new therapies

Chronic pancreatitis occurs by the prolonged inflammation of pancreatic tissue that induces the irreversible destruction of the organ, leading to a global pancreatic insufficiency. The most common manifestations are abdominal pain, diarrhea, malabsorption, and possibly diabetes mellitus. Chronic pancreatitis treatment includes dietary restrictions, enzymatic supplementation, vitamins, and endoscopic or surgical methods depending on the degree of ductal involvement. In addition to the known therapies, new therapies are under development and research.

La pancreatitis crónica se desarrolla por la inflamación prolongada del tejido pancreático que induce la destrucción irreversible del órgano, llevando a una insuficiencia pancreática global. Las manifestaciones más frecuentes son dolor abdominal, diarrea, malabsorción y eventualmente diabetes mellitus. El tratamiento en pancreatitis crónica incluye restricciones dietarias, suplementación enzimática, vitamínica, y métodos endoscópicos o quirúrgicos, dependiendo del grado de compromiso ductal. Además de lo descrito, están en desarrollo y experimentación nuevas terapias.
