Recurrent acute and chronic pancreatitis in two brothers with familial chylomicronemia syndrome

The chylomicronemia syndrome is well recognized as a rare etiologic factor of acute pancreatitis; however, whether hypertriglyceridemia can cause chronic pancreatitis (CP) remains unclear. We describe the long-time course of 2 brothers with the familial chylomicronemia syndrome caused by identical compound heterozygous mutations in the lipoprotein lipase (LPL) gene with markedly reduced LPL activity. Other etiologic factors were excluded, including mutations in the PRSS1, SPINK1, and CFTR gene. Although both brothers had recurrent acute pancreatitis and the same LPL genotype, CP became evident in only one patient. Progression to CP was associated with a more severe disease course. Thus, the chylomicronemia syndrome may cause CP in the absence of other known causative factors, and similar to alcoholic and hereditary CP, a more severe disease course is associated with disease progression.

Corticosteroid-binding globulin: a possible early predictor of infection in acute necrotizing pancreatitis

OBJECTIVE: Infected pancreatic necrosis is the main cause of death in patients with acute pancreatitis, and therefore its early prediction is of utmost importance. Endogenous cortisol metabolism plays a basic role both in the course of acute pancreatitis and in the process of infection. The purpose of this study was to analyze corticosteroid-binding globulin (CBG), total cortisol, calculated free cortisol and adrenocorticotropic hormone as potential early predictors in order to differentiate between infected pancreatic necrosis and sterile pancreatic necrosis in patients with acute pancreatitis. MATERIAL AND METHODS: Serum levels of CBG, total cortisol, calculated free cortisol, and plasma levels of adrenocorticotropic hormone were determined in 109 consecutive patients with acute pancreatitis. C-reactive protein was measured as the control parameter. Thirty-five patients developed necrotizing pancreatitis and 10 developed infection of the necrosis. Blood was monitored for 6 days after the onset of pain; 30 healthy individuals served as controls. RESULTS: Of all parameters only CBG showed a significant difference (p = 0.0318) in its peak levels measured in the first 48 h in patients with sterile (26.5 microg/ml, range 21.3-34.7) and infected (16.0 microg/ml, range 15.2-25.0) necrosis at a cut-off level of 16.8 microg/ml. That difference was further preserved for the first 6 days after onset of pain. CONCLUSIONS: In our group of patients, a decreased CBG level below 16.8 g/ml within the initial 48 h of acute pancreatitis was an early predictor of later infected pancreatic necrosis, with a positive predictive value of 100% and a negative predictive value of 87.5%.

Acute hemorrhagic necrotizing pancreatitis in falciparum malaria

Malaria is a pathology caused by a parasite called Plasmodium, characteristic of tropical countries. The most frequent symptomatology includes cerebral malaria, jaundice, convulsive crisis, anemia, hypoglycemia, kidney failure and metabolic acidosis, among others. We are presenting the case of a patient diagnosed with malaria who suffered from acute hemorrhagic necrotizing pancreatitis and evolved poorly, as an example of this combination of symptoms, rarely found in our country.

Influence of delayed cholecystectomy after acute gallstone pancreatitis on recurrence: consequences of lack of resources

Introduction: Acute pancreatitis is often a relapsing condition, particularly when its triggering factor persists. Our goal is to determine the recurrence rate of acute biliary pancreatitis after an initial episode, and the time to relapse, as well as to identify the risk factors for recurrence. Material and method: We included all patients admitted for a first acute gallstone pancreatitis event during four years. Primary endpoints included readmission for recurrence and time to relapse. Results: We included 296 patients admitted on a total of 386 occasions. The incidence of acute biliary pancreatitis in our setting is 17.5/100,000 population/year. In all, 19.6% of pancreatitis were severe (22.6% of severe acute pancreatitis for first episodes versus 3.6% for recurring pancreatitis), with an overall mortality of 4.4%. Overall recurrence rate was 15.5%, with a median time to relapse of 82 days. In total, 14.2% of patients relapsed after an acute pancreatitis event without cholecystectomy or endoscopic retrograde cholangio-pancreatography. Severe acute pancreatitis recur in 7.2% of patients, whereas mild cases do so in 16.3%, this being the only risk factor for recurrence thus far identified. Conclusions: Patients admitted for pancreatitis should undergo cholecystectomy as soon as possible or be guaranteed priority on the waiting list. Otherwise, endoscopic retrograde cholangio-pancreatography with sphincterotomy may be an alternative to surgery for selected patients.

Interleukin 10 reduces the incidence of pancreatitis after therapeutic endoscopic retrograde cholangiopancreatography.

BACKGROUND & AIMS: Prophylactic administration of interleukin (IL)-10 decreases the severity of experimental pancreatitis. Prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis in humans is a unique model to study the potential role of IL-10 in this setting. METHODS: In a single-center, double-blind, randomized, placebo-controlled study, the effect of a single injection of 4 microg/kg (group 1) or 20 microg/kg (group 2) IL-10 was compared with that of placebo (group 0), all administered 30 minutes before therapeutic ERCP. The primary endpoint was the effect of IL-10 on serum levels of amylases and lipases measured 4, 24, and 48 hours after ERCP. The secondary objective was to evaluate changes in plasma cytokines (IL-6, IL-8, tumor necrosis factor) at the same time points and the incidence of acute pancreatitis in the 3 groups. Subjects undergoing a first therapeutic ERCP were eligible for inclusion. RESULTS: A total of 144 patients were included. Seven were excluded based on intention to treat (n = 1) or per protocol (n = 6). Forty-five, 48, and 44 patients remained in groups 0, 1, and 2, respectively. The 3 groups were comparable for age, sex, underlying disease, indication for treatment, type of treatment, and plasma levels of C-reactive protein (CRP), cytokines, and hydrolases at baseline. No significant difference was observed in CRP, cytokine, and hydrolase plasma levels after ERCP. Forty-three patients developed hyperhydrolasemia (18 in group 0, 14 in group 1, and 11 in group 2; P = 0.297), and 19 patients developed acute clinical pancreatitis (11 in group 0, 5 in group 1, 3 in group 2; P = 0.038). Two severe cases were observed in the placebo group. No mortality related to ERCP was observed. Logistic regression identified 3 independent risk factors for post-therapeutic ERCP pancreatitis: IL-10 administration (odds ratio [OR], 0.46; 95% confidence interval [95% CI], 0.22-0.96; P = 0.039), pancreatic sphincterotomy (OR, 5.04; 95% CI, 1.53-16.61; P = 0.008), and acinarization (OR, 8.19; 95% CI, 1.83-36.57; P = 0.006). CONCLUSIONS: A single intravenous dose of IL-10, given 30 minutes before the start of the procedure, independently reduces the incidence of post-therapeutic ERCP pancreatitis.

Endogenous interleukin-10 modulates fibrosis and regeneration in experimental chronic pancreatitis.

Interleukin (IL)-10, a potent anti-inflammatory cytokine, limits the severity of acute pancreatitis and downregulates transforming growth factor (TGF)-beta release by inflammatory cells on stimulation. Proinflammatory mediators, reactive oxygen species, and TGF-beta can activate pancreatic stellate cells and their synthesis of collagen I and III. This study evaluates the role of endogenous IL-10 in the modulation of the regeneration phase following acute pancreatitis and in the development of pancreatic fibrosis. IL-10 knockout (KO) mice and their C57BL/6 controls were submitted to repeated courses (3/wk, during 6 wk, followed by 1 wk of recovery) of cerulein-induced acute pancreatitis. TGF-beta(1) release was measured on plasma, and its pancreatic expression was assessed by quantitative RT-PCR and immunohistochemistry. Intrapancreatic IL-10 gene expression was assessed by semiquantitative RT-PCR, and intrapancreatic collagen content was assessed by picrosirius staining. Activated stellate cells were detected by immunohistochemistry. S phase intrapancreatic cells were marked using tritiated thymidine labeling. After repeated acute pancreatitis, IL-10 KO mice had more severe histological lesions and fibrosis (intrapancreatic collagen content) than controls. TGF-beta(1) plasma levels, intrapancreatic transcription, and expression by ductal and interstitial cells, as well as the number of activated stellate cells, were significantly higher. IL-10 KO mice disclosed significantly fewer acinar cells in S phase, whereas the opposite was observed for pseudotubular cells. Endogenous IL-10 controls the regeneration phase and limits the severity of fibrosis and glandular atrophy induced by repeated episodes of acute pancreatitis in mice.

Correlación entre la escala clínica de Apache II y la imagenológica de Balthazar en la evaluación de pancreatitis aguda severa en pacientes adultos de la Fundación Cardioinfantil entre 2008-2010

El diagnóstico oportuno en pancreatitis aguda es clave para abordar adecuadamente al paciente, para disminuir complicaciones. En la evaluación de la severidad de la pancreatitis, se cuenta con la escanografía; útil en la determinación de complicaciones locales; sin embargo, es necesario establecer su correlación con el curso clínico del paciente, evaluado mediante la escala APACHE II que cuenta con diversas variables. METODOLOGIA: Determinar la correlación entre las escalas clínica e imagenológica en la evaluación de severidad de la pancreatitis. Para esto, se revisan historias clínicas de la Fundación Cardio - Infantil de pacientes con pancreatitis aguda, se revisa si cumplen criterios de inclusión, y se emplea análisis estadístico descriptivo en SPSS, para establecer correlación entre las variables. RESULTADOS: Existe pobre correlación entre las variables, porque son escalas que evalúan parámetros diferentes, lo que hace que estas escalas se complementen. DISCUSION: Se analizaron 189 pacientes, de una población de 264; los restantes no cumplían criterios de inclusión. Las características demográficas y la etiología de la pancreatitis son muy similares a las descritas en otros estudios. Se tomaron paraclínicos para definir criterios de Ramson; y se les realizó escanografía abdominal para buscar complicaciones locales; de acuerdo a la escala BALTHAZAR-INDICE DE SEVERIDAD; y la evaluación clínica APACHE II, para hacer seguimiento clínico. El criterio de ingreso a UCI se evalúa con la escala APACHE II que puede hacerse periódicamente; posteriormente se evaluó coeficientes de correlación entre las variables con mayor impacto en pronóstico. PALABRAS CLAVES: Pancreatitis aguda, Severidad, Apache II, BALTHAZAR

Efecto de la restitución temprana de la nutrición oral en la pancreatitis aguda leve

Aunque el manejo nutricional de los pacientes con Pancreatitis Aguda Severa ha sido bien establecido por la evidencia disponible, el inicio de la vía oral en Pancreatitis Leve no ha sido igualmente estudiado. El objetivo de este estudio es evaluar el efecto del inicio temprano de la nutrición por vía oral en estos pacientes. Métodos: Realizamos un descriptivo serie de comparación de casos en los cuales comparamos la evolución y resultados del manejo de los pacientes con pancreatitis aguda antes y después de iniciar un protocolo de inicio temprano de nutrición por vía oral. Resultados: La serie incluyó 13 pacientes manejados con restitución convencional y 9 pacientes a quienes se restituyó tempranamente la nutrición oral. No existieron diferencias estadísticamente significativas en cuanto las características clínicas, etiológicas y demográficas entre los grupos. No se presentaron casos de progresión a enfermedad severa en ninguno de los grupos. La aparición de síntomas gastrointestinales como vomito y dolor después del inicio de la dieta fue similar en los dos grupos. Conclusiones: La restitución de la nutrición por vía oral basada criterios preestablecidos (la intensidad del dolor menor de 4 y un periodo mayor a 6 horas desde el último episodio emético) es segura y disminuye el periodo de ayuno inicial mas no el de estancia hospitalaria.

Valor diagnostico de la colangioresonancia para la detección de coledocolitiasis en pancreatitis aguda Hospital Mederi-Bogotá

La pancreatitis aguda (PA) es una patología clínica común que abarca un espectro desde leve hasta fatal, donde se produce una inflamación del páncreas por auto digestión enzimática con grado variable de compromiso sistémico. Es una emergencia abdominal grave con una mortalidad del 9-23%. En el 40% de los casos de pancreatitis aguda se encuentra que es de origen biliar. La prevalencia de enfermedad biliar a nivel mundial en adultos varía entre 5,9% y 21,9%, con grandes variaciones geográficas y regionales, se encuentran en el 12% de los hombres y el 24% de las mujeres. La prevalencia aumenta con la edad. Latinoamérica es una región con alta prevalencia. En pacientes con colelitiasis del 5-15 % tienen coledocolitiasis. La alta prevalencia de la patología biliar en nuestro país hace que esta sea una causa frecuente de consulta médica por dolor abdominal. El factor común presente en la gran mayoría de las enfermedades de la vía biliar es la Colelitiasis. La complicación más frecuente, la Coledocolitiasis, se ha reportado con cifras hasta de un 20% y como complicación de esta la pancreatitis. La pancreatitis aguda de origen biliar (PAB) es causada por una obstrucción transitoria o persistente de la ampolla de Váter por barro biliar o por cálculos. En el diagnostico de la PAB se emplean métodos invasivos como la colangiopancreaticografia endoscópica retrograda (CPRE) la cual trae consigo morbilidad y mortalidad asociada y métodos no invasivos como la colangiopancreaticografia magnética (CRM) que emerge como modalidad prometedora en el diagnostico y manejo de la PAB en centros de tercer y cuarto nivel de complejidad. El manejo actual de la PAB es la remoción de la obstrucción del conducto biliar común (CBC) seguida de su tratamiento definitivo, la colecistectomía o CPRE con papilotomia. En nuestro país no se han publicado estudios con datos locales acerca de la utilidad de la CRM para la detección de coledocolitiasis, en las guías de manejo de coledocolitiasis de la asociación colombiana de cirugía publicadas en el año 2004, hace referencia de la utilidad de la CRM para el diagnostico de esta entidad tomando como base una revisión sistemática de estudios publicados en Medline, Pubmed y Cocrane los cuales no incluyen experiencia a nivel nacional. En este estudio pretendimos determinar cuáles son los pacientes que se benefician de la realización de CRM temprana en el marco de la PAB leve para la detección de coledocolitiasis.

Comparación de CPRE temprana y tardia en pacientes con pancreatitis aguda severa de origen biliar

INTRODUCCION: La obstrucción biliar es la principal causa de pancreatitis aguda y su curso es moderado a leve aunque un 20% desarrollan formas severas. La remoción de los cálculos por CPRE se ha empleado como terapéutica aunque su rol es controversial y no se ha demostrado su utilidad en forma temprana. El propósito de este estudio es observar la evolución de los pacientes con PASB en quienes se realice CPRE con respecto al curso de la enfermedad. METODOLOGIA: Estudio retrospectivo observacional descriptivo en pacientes con PASB llevados a CPRE. Entre junio y octubre de 2012 se encontraron 72 pacientes con PASB y patrón biliar obstructivo, 49 (68.06%) en los cuales se realizo de forma temprana (antes de 72 horas) y 23 (31,94 %) de forma tardía (después de las 72 horas). RESULTADOS: No se encontraron diferencias en la morbilidad entre los dos grupos observados. Se encontró una mayor incidencia de PASB en mujeres, no hubo complicaciones asociadas al procedimiento y no hubo mortalidad asociada en ninguno de los grupos. DISCUSION: El estudio no muestra que la realización de CPRE tardía influya de forma desfavorable en los pacientes con PASB. Se encontró mayor incidencia de PASB en mujeres y edad media de 61 años. Deben realizarse mas estudios como el presente con un mayor número de pacientes para demostrar que no hay aumento en la morbimortalidad en los pacientes que sean llevados a CPRE después de 72 horas de inicio de los síntomas y poder generar recomendaciones de manejo locales.

Pancreatitis subtypes survey in 852 childhood-onset systemic lupus erythematosus patients: a multicenter cohort

Pancreatitis is a rare and a life-threatening SLE manifestation in childhood-onset systemic lupus erythematosus (c-SLE). The objective of this study was to systematically classify pancreatitis in c-SLE according to the International Study Group of Pediatric Pancreatitis (INSPPIRE) and determine the overall prevalence, clinical features, laboratory and first episode outcomes. A multicenter cohort study in 10 Pediatric Rheumatology centers, including 852 cSLE patients. Pancreatitis was diagnosed in 22/852 (2.6%) cSLE patients. It was classified as acute pancreatitis in 20 (91%), acute recurrent pancreatitis in 2 (9%) and none of them had chronic pancreatitis. None of them had gallstones, traumatic pancreatitis or reported alcohol/tobacco use. The comparison of patients with pancreatitis (first episode) and without this complication revealed a shorter disease duration [1(0-10) vs. 4(0-23) years, p < 0.0001] and higher median of SLEDAI-2K [21(0-41) vs. 2(0-45), p < 0.0001]. The frequencies of fever (p < 0.0001), weight loss (p < 0.0001), serositis (p < 0.0001), nephritis (p < 0.0001), arterial hypertension (p < 0.0001), acute renal failure (p < 0.0001), macrophage activation syndrome (p < 0.0001) and death (p = 0.001) were also higher in patients with pancreatitis. The frequencies of intravenous methylprednisolone use (p < 0.0001) and the median of prednisone dose [55(15-60) vs. 11(1-90)mg/day, p < 0.0001] were significantly higher in patients with pancreatitis. Of note, the two patients with acute recurrent pancreatitis had two episodes, with pain-free interval of 1 and 4 years. This was the first study characterizing pancreatitis using the INSPPIRE standardized definitions in patients with cSLE showing that the predominant form is acute pancreatitis seen in association with glucocorticoid treatment and active severe disease.

Evaluation of the Effects of a Preoperative 2-Hour Fast With Maltodextrine and Glutamine on Insulin Resistance, Acute-Phase Response, Nitrogen Balance, and Serum Glutathione After Laparoscopic Cholecystectomy: A Controlled Randomized Trial

Background: Prolonged preoperative fasting increases insulin resistance (IR). The authors investigated whether an abbreviated preoperative fast with glutamine (GLN) plus a carbohydrate (CHO)-based beverage would improve the organic response after surgery. Methods: Forty-eight female patients (19-62 years) were randomized to either standard fasting (control group) or to fasting with 1 of 3 different beverages before video-cholecystectomy. Beverages were consumed 8 hours (400 mL; placebo group: water; GLN group: water with 50 g maltodextrine plus 40 g GLN; and CHO group: water with 50 g maltodextrine) and 2 hours (200 mL; placebo: water; GLN: water with 25 g maltodextrine plus 10 g GLN; and CHO: water with 25 g maltodextrine) before anesthesia. Blood samples were collected pre- and postoperatively. Results: The mean (SEM) postoperative homeostasis model assessment-insulin resistance was greater (P < .05) in control patients (4.3 [1.3]) than in the other groups (placebo, 1.6 [0.3]; CHO, 2.3 [0.4]; and GLN, 1.5 [0.1]). Glutathione was significantly higher (P < .01) in the GLN group than in both CHO and control groups. Interleukin-6 increased in all groups except the GLN group. The C-reactive protein/albumin ratio was higher (P < .05) in controls than in CHO and GLN groups. The nitrogen balance was less negative in GLN (-2.5 [0.8] gN) than in both placebo (-9.0 [2] gN; P = .001) and control (-6.6 [0.4] gN; P = .04) groups. Conclusions Preoperative intake of a GLN-enriched CHO beverage appears to improve IR and antioxidant defenses and decreases the inflammatory response after video-cholecystectomy.

International Consensus Guidelines for Nutrition Therapy in Pancreatitis

Guidelines for nutrition support in pancreatitis have been inconsistently adapted to clinical practice. The International Consensus Guideline Committee (ICGC) established a pancreatitis task force to review published guidelines for pancreatitis in nutrition support. A PubMed search using the terms pancreatitis, acute pancreatitis, chronic pancreatitis, nutrition support, parenteral nutrition, enteral nutrition, and guidelines was conducted for the period from January 1999 to May 2011. Eleven guidelines were identified for review. The ICGC used the following process to develop unified guideline statements: summarize the strength of evidence (grading) of the guidelines; establish level of evidence for ICGC statements as high, intermediate, and low; assign published guideline levels of evidence; and define an ICGC grading system. International Pancreatitis Guideline Grades were established as follows: platinum-high level of evidence and consistent agreement among the guidelines; gold-acceptable level of evidence and no conflicting statements in guidelines; and silver-single existing guideline statement with no conflict in other guidelines. Eighteen ICGC statements were derived from the 11 published pancreatitis guidelines. Uniform agreement from widely disparate groups (United States, Europe, Japan, and China) resulted in 4 platinum-level guideline statements for nutrition in pancreatitis: nutrition support therapy (NST) is generally not needed for mild to moderate disease, NST is needed for severe disease, enteral nutrition (EN) is preferred over parenteral nutrition (PN), and use PN when EN is contraindicated or not feasible. This methodology provides a template for future ICGC nutrition guideline development. (JPEN J Parenter Enteral Nutr. 2012;36:284-291)

Unusual tomographic findings of complicated necrotizing pancreatitis

Acute pancreatitis (AP) is a potential life-threatening disease, which originates from inflammatory involvement of the pancreas and surrounding tissues. Serious complications eventuate and treatment is difficult. AP is classified in both interstitial edematous pancreatitis, which occurs in 70-80% of patients, and necrotizing pancreatitis, which occurs in 20-30% of patients. Diagnosis is based on the presence of two of the following criteria: abdominal pain, increased serum determination of amylase and/or lipase more than three times the reference value, and characteristic tomographic findings. Among the latter, there is the pancreatic and surrounding tissue damage as well as that related to distant organ involvement. This case report shows the fatal case of a male patient with a history of heavy alcoholic abuse admitted with the diagnosis of necrotizing pancreatitis. The authors call attention to the unusual tomographic findings; namely, a huge duodenal hematoma and a large hemoperitoneum, ischemic involvement of the spleen and kidneys, as well as pancreatic and peripancreatic necrosis.
