Resolution of fatty liver disease after growth hormone replacement in a pediatric survivor of thyroid cancer / Resolución de enfermedad hepática grasa posterior al reemplazo con hormona de crecimiento en un paciente pediátrico sobreviviente a cáncer de tiroides

Abstract Background A rare case of primary papillary thyroid cancer (PTC) and growth hormone (GH) deficiency in a pediatric patient is described. In addition, the patient developed fatty liver disease attributed to GH deficiency. Case report A 10-year-old male with a history of PTC with extension to the cervical nodes detected at 5 years of age was referred to the endocrinology consultation due to a low growth rate. On examination, GH deficiency was detected (height −3.51 standard deviations and low insulin-like growth factor-1 levels). This hormonal deficiency was not associated with thyroid cancer or treatment. Furthermore, elevated transaminases (~300 IU/ml), lipids, and fally liver disease by ultrasound were detected. These data suggested fatty liver disease, which was attributed to GH deficiency. Regardless of the risk of recurrence, somatotropin was administered due to liver dysfunction and very short stature of the patient. A considerable improvement in growth, transaminases, and lipid profile was observed. At present, at 14 years of age, resolution of hepatic steatosis and a considerable increase in his growth rate without recurrence of thyroid cancer 9 years after its diagnosis and 4 years after the initiation of GH treatment are confirmed. Conclusions GH therapy could be a good therapeutic option for pediatric cancer survivors to address impaired growth and fatty liver disease. However, additional medical evidence based on clinical trials is necessary to determine the benefits.

Resumen Introducción Se presenta el caso de un paciente pediátrico con una asociación de cáncer papilar de tiroides (CPT) y deficiencia de hormona de crecimiento (HC) que no ha sido descrita previamente. Además, presenta enfermedad hepática grasa atribuida a la deficiencia hormonal. Caso clínico Paciente de sexo masculino con antecedente de CPT con extensión a los ganglios cervicales diagnosticado a los 5 años de edad. Es referido a los 10 años por talla baja, sin datos de recurrencia del CPT. En el abordaje diagnóstico se detecta deficiencia de HC basándose en una estatura 3.51 desviaciones estándar por debajo de la media y niveles bajos de factor de crecimiento insulínico tipo 1. Adicionalmente, se detectó elevación de transaminasas (~300 IU/ml), dislipidemia y esteatosis hepática en el ultrasonido. Después de los estudios de extensión, la enfermedad hepática grasa se atribuyó a la deficiencia de HC. A pesar del riesgo de recurrencia del cáncer de tiroides, se decidió dar tratamiento con HC debido a la afectación hepática y de crecimiento. El paciente presentó una evolución satisfactoria y actualmente, a la edad de 14 años, la esteatosis hepática está resuelta, presenta una mejoría considerable en su estatura y no ha tenido recurrencia del cáncer de tiroides 9 años después del diagnóstico y 4 años después del inicio del tratamiento con HC. Conclusiones El tratamiento con HC puede ser una adecuada opción terapéutica para sobrevivientes de cáncer en la edad pediátrica con afectación en el crecimiento y esteatosis hepática.

Emergency double-balloon enteroscopy combined with real-time viewing of capsule endoscopy: a feasible combined approach in acute overt-obscure gastrointestinal bleeding?

BACKGROUND AND AIM: There are few data concerning emergency double-balloon enteroscopy (DBE) and its usefulness in the management of severe acute obscure gastrointestinal bleeding (OGIB). The aim of this retrospective study was to evaluate emergency DBE and capsule endoscopy (CE) in patients with overt OGIB, analyzing the feasibility of this combined approach. METHODS: Emergency DBE in patients with overt OGIB was defined as performance within 24 h of symptom onset. We reported 27 patients (16 men, mean age: 64.6 ± 17.9 years) with overt severe bleeding who underwent 29 emergency DBE (22 anterograde, 7 retrograde). Of 27 patients, 16 (59.3%) underwent CE with real time (RT) viewing. RESULTS: Patients were diagnosed with the following: Dieulafoy's lesion (DL; n = 11, 40.7%), angioectasia (n = 7, 25.9%), tumors (n = 4, 14.8%), diverticulum (n = 3, 11.1%), ulcers (n = 2, 7.4%). We diagnosed 23 lesions amenable to endoscopic hemostasis and successfully treated 21 of them (77.8%). DL detection rate was statistically higher in the emergency DBE group than in OGIB patients with DBE done 24 h after symptom onset (40.7% vs 0.9%, respectively, P < 0.001). Combined approach with RT viewing by CE correctly modified DBE management in four patients (25%). CONCLUSIONS: Emergency DBE is feasible, safe and effective in acute OGIB and may avoid major surgery, diagnosing and successfully treating most patients. Combined approach with RT viewing by CE is especially useful to identify recurrent bleeding vascular lesions such as DL that may be easily misdiagnosed by non-emergency DBE.
