The use of serum calprotectin as a biomarker for inflammatory activity in inflammatory bowel disease.

INTRODUCTION: simple, reliable and non-invasive biomarkers are needed to enable the early detection of inflammatory activity for the correct management of inflammatory bowel disease (IBD). One of these biomarkers may be serum calprotectin (SC). MATERIAL AND METHODS: a prospective study was performed of patients with IBD due to undergo a colonoscopy as part of the common clinical practice. The study parameters included SC, fecal calprotectin (FC) and conventional blood test parameters. Clinical indices (Harvey and Walmsley) and relevant endoscopic scores were completed for each scenario (Simple Endoscopic Score Crohn Disease [SES-CD] and Mayo). RESULTS: fifty-three patients were included in the study, 51% (27 patients) with ulcerative colitis (UC) and 49% (26 patients) with Crohn's disease (CD). The CS values in UC were significantly higher with an endoscopic Mayo score 2/3 (median score 10.39 mg/ml [IQR: 7.4-12.2]) compared to those with a Mayo score of 0/1 (median 4.07 mg/ml [IQR: 2.9-7.2]) (p = 0.01). The area under the ROC curve (AUCROC) was 0.85 and the sensitivity and specificity were 83.3% and 81.25%, respectively, for a SC cut-off point of 4.4 mg/dl. Furthermore, a higher AUCROC was obtained in comparison with other serological markers for activity (C-reactive protein [CRP], erythrocyte sedimentation rate [ESR], hemoglobin [Hb] and platelets). There were no statistically significant differences in the comparison between SC and endoscopic findings in CD (SES CD > 3: 20.1 [IQR: 16.8-23.4] vs SESC ≤ 3:6.25 [IQR: 5.4-7.1]) (p = 0.8). CONCLUSIONS: SC is a good indirect marker of inflammatory activity and there was a correlation with endoscopic findings in UC. However, there were no statistically significant differences in the case of CD.

Ultrasound-guided percutaneous drainage and sclerotherapy in a patient with isolated autosomal dominant polycystic liver disease.

Isolated polycystic liver disease (IPLD) is a rare genetic condition characterized by the presence of multiple liver cysts with no association with polycystic kidney disease. Most patients are asymptomatic and acute complications (cyst torsion, bleeding, infection) are uncommon.Imaging techniques, including abdominal ultrasounds, computerized axial tomography, and magnetic resonance imaging, represent a vital diagnostic modality. They are also useful for therapy support in this disease. Below we report a peculiar case of a female patient recentlydiagnosed with IPLD who, having received treatment with ultrasoundguided percutaneous drainage and sclerotherapy for a giant liver cyst, showed symptom and laboratory improvement.

Drenaje percutáneo y escleroterapia guiada por ecografía en paciente con poliquistosis hepática aislada autosómica dominante / Ultrasound-guided percutaneous drainage and sclerotherapy in a patient with isolated autosomal dominant polycystic liver disease

La enfermedad hepática poliquística aislada (EHPA), es una rara entidad genética que se caracteriza por la presencia de múltiples quistes hepáticos, sin estar asociada a la poliquistosis renal. La mayoría de los pacientes son asintomáticos, y son infrecuentes las complicaciones agudas (torsión quística, hemorragia e infecciones). Las técnicas de imagen, como la ecografía abdominal, tomografía axial computarizada y resonancia magnética, son un método diagnóstico fundamental. Además, son útiles como apoyo terapéutico en esta enfermedad. A continuación les presentamos un caso clínico peculiar de una paciente recientemente diagnosticada de enfermedad hepática poliquística aislada, quien tras recibir un tratamiento con drenaje percutáneo de un quiste hepático gigante y escleroterapia guiada por ecografía, presentó mejoría sintomática y analítica

Utilidad de la calprotectina sérica como biomarcador de actividad inflamatoria en la enfermedad inflamatoria intestinal / The use of serum calprotectin as a biomarker for inflammatory activity in inflammatory bowel disease

Introducción: para el correcto manejo de la enfermedad inflamatoria intestinal (EII) precisamos de marcadores no invasivos, fiables y sencillos que permitan detectar la actividad inflamatoria de forma precoz. Uno de estos marcadores biológicos podría ser la calprotectina sérica (CS). Material y métodos: inclusión prospectiva de pacientes con EII que iban a realizarse una colonoscopia por práctica clínica habitual. Se determinaron: CS, calprotectina fecal (CF) y parámetros analíticos convencionales. Se realizaron los índices clínicos (Harvey y Walmsley) así como los endoscópicos correspondientes en cada escenario (Simple Endoscopic Score Crohn Disease [SES-CD] y Mayo). Resultados: se incluyeron 53 pacientes; el 51% (27 pacientes) con colitis ulcerosa (CU) y el 49% (26 pacientes) con enfermedad de Crohn (EC). En CU los valores de CS fueron significativamente superiores con actividad endoscópica Mayo 2/3 (mediana 10,39 mg/ml [IQR: 7,4-12,2]) frente aquellos con Mayo 0/1 (mediana 4,07mg/ml [IQR: 2,9-7,2]) (p = 0,01). El área bajo la curva ROC (AUCROC) fue 0,85, obteniendo para un punto de corte de CS de 4,4 mg/dl una sensibilidad y especificidad del 83,3% y 81,25%, respectivamente. Además, al comparar con otros marcadores serológicos de actividad (proteína C reactiva [PCR], velocidad de sedimentación globular [VSG], hemoglobina [Hb] y plaquetas) se obtuvo un AUCROC superior. Cuando comparamos la CS con los hallazgos endoscópicos en EC, no hubo diferencias estadísticamente significativas (SES CD > 3: 20,1 [IQR: 16,8-23,4] vs. SESC ≤ 3:6,25 [IQR: 5,4-7,1]) (p = 0,8). Conclusiones: la CS es un buen marcador indirecto de la actividad inflamatoria y existe correlación con los hallazgos endoscópicos en CU, aunque sin diferencias estadísticamente significativas en EC
