[Association between ulcerative colitis and primary esclerosing cholangitis]. / Asociación entre colitis ulcerativa y colangitis esclerosante primaria.

Ulcerative Colitis (UC) is associated to Primary Sclerosing Cholangitis (PSC) in 80% of cases, and this association is more common than the one with Crohn’s disease. Nevertheless, the prevalence of PSC in patients with UC is only 2.9% in Latin America. We present the case of a female patient who presents a clinical history characterized for chronic diarrhea of one year of evolution, associated to fever, oral ulcers and loss of weight. In the laboratory results there is an elevation in the following: alkaline phosphatase, GGT, ALT and AST, for that reason we decide to do an abdominal ultrasound finding a hepatomegaly. In the colonoscopy we found an ulcerative colitis. Later, we do a magnetic resonance cholangiopancreatography, because of the diagnosis of UC and the abnormalities at the liver function tests, diagnosing PSC associated to UC. At that moment, the patient starts treatment with sulfasalazine that is stopped because of an adverse effect, starting prednisone and azathioprine. The patient then is discharged with the medication already mentioned and has a favorable clinical outcome. We decide to report the case because is the second reported case in Peru, being this association not commonly found in the South hemispheric.

Gastric Electrical Stimulation Has an Effect on Gastric Interstitial cells of Cajal (ICC) That is Associated With Mast Cells.

Introduction Gastric electrical stimulation (GES) is an emerging therapy for gastric motility disorders, showing improvement of gastroparesis related symptoms in previous studies. Interstitial cells of Cajal (ICC) and mast cells have been shown to have a relevant role in gastroparesis pathogenesis. However, the exact effects of GES in those cells is relatively unknown. Methods Full thickness biopsies (FTBx) of 20 patients with refractory gastroparesis were obtained at the time of GES placement and repeated when the device was exchanged (mean of 22.5 months between biopsies). A patient-reported outcomes survey was obtained during each office visit during this period. All biopsies were stained with cluster of differentiation 117 (CD117), S100, and mast cell tryptase antibodies and were analyzed. Results Half of the patients had a significant increase of ICC during the repeated biopsy compared with baseline (p=0.01) and the other half had significant decrease in ICC levels (p=0.006) but there was no noticeable difference in mast cells counts at baseline between groups. Mast cells analysis was performed in two different groups depending on ICC change from the baseline biopsy (CD117 increase vs CD117 decrease). There was only a significant increase of mast cells count within the CD117 worsened ICC group (p=0.007). Conclusion No significant increase in the number of mast cells count seen in patients who received a GES may indicate an improvement in overall inflammation in patients with refractory gastroparesis after GES placement.

La Colitis Ulcerativa (CU) está asociada a la Colangitis Esclerosante primaria (CEP) en 80% de los casos y esta concurrencia entre CEP y CU es mayor en comparación con la enfermedad de Crohn. Sin embargo, la prevalencia de CEP en pacientes con CU es sólo 2,9% en Latinoamérica. Presentamos el caso de una paciente mujer que presenta un cuadro caracterizado por diarrea crónica de un año de evolución, asociado a sensación de alza térmica, ulceras orales y pérdida de peso. En los exámenes auxiliares se encuentra una fosfatasa alcalina, GGT, TGO y TGP elevados por ello se decide realizar una ecografía abdominal encontrándose hepatomegalia. En el examen de colonoscopia se encuentran hallazgos compatibles con colitis ulcerativa. Entonces se realiza una colangioresonancia debido al diagnóstico de CU y las anormalidades en los valores de función hepática; diagnosticándose CEP asociada a CU. Es así que la paciente recibe tratamiento con sulfazalasina que se suspende por efecto adverso, iniciándose prednisona y azatioprina. La paciente es dada de alta con el tratamiento ya descrito y tiene buena evolución clínica. Se decide reportar el presente caso debido a que es el segundo caso reportado en el Perú, siendo esta asociación poco frecuente en el hemisferio sur...
