Disseminated Langerhans' cell histiocytosis and massive protein-losing enteropathy

Symptomatic involvement of the gastrointestinal (GI) tract as a prominent symptom in Langerhans' cell histiocytosis (LCH) is uncommon, occurring in less than 1 to 5 percent of all cases, even when the disease is in its disseminated form. Up to now, there have been reports of 18 cases of LCH with GI manifestations, including our 2 cases, with diarrhea (77.7 percent), protein-losing enteropathy (33.3 percent) and bloody stool being the most frequent findings. The authors present two patients with severe diarrhea and refractory hypoalbuminemia, and with the protein-losing enteropathy documented by Cr51-labeled albumin studies. A review of the literature indicated that the presence of GI symptoms is often associated with systemic disease as well as with poor prognosis, mainly under 2 years of age. Radioisotopes are useful for documenting protein loss in several diseases with high specificity and sensitivity, and their utilization in the cases reviewed here permitted diagnoses in 6 children, as well as improved therapeutic management

Secretory diarrhea with protein-losing enteropathy, enterocolitis cystica superficialis, intestinal lymphangiectasia, and congenital hepatic fibrosis: a new syndrome.

Four infants had noninfectious intractable diarrhea, vomiting, anasarca, hepatomegaly, hypoglycemia, and malnutrition within the first 3 months of life. Their parents originated from the same Northeastern part of Quebec, and consanguinity was found in two kindreds. Diarrhea was secretory in three infants (mean stool volume 87 ml/kg/day, Na+ 108 mEq/L, Cl- 85 mEq/L). Hypoalbuminemia (mean 2.0 gm/dl), present in all infants, appeared to be secondary to a protein-losing enteropathy, which was documented in two infants. Histologic examination of the upper small intestine showed only mild to moderate villous atrophy. The remarkable findings were those of cystic dilation of the crypts and acute inflammation of crypts and lamina propria, all of which were most prominent in the colon and terminal ileum; the changes were progressive over time. Mild lymphangiectasia was found in all of the patients. Congenital hepatic fibrosis, present in all, was associated in one patient with a nonfunctional multicystic kidney. Prolonged total parenteral nutrition, intravenously administered albumin, antisecretory agents, and antibiotics were unsuccessful in controlling the disease. Although a total colectomy was followed by a temporary decrease in stool output and normalization of serum albumin concentration in one infant, the patients died between 4 and 21 months of age.

Intestinal lymphangiectasia: clinical aspects and diagnostic contribution of endoscopic biopsies. Case report.

A case of a 5 1/2 year old girl with intestinal lymphangiectasia is described. The diagnosis was established by endoscopic biopsies. The value of endoscopy is discussed and, clinical aspects and management difficulties are stressed.

Enfermedad celíaca: estudio de 36 casos / Celiac disease: a study on 36 children

Se estudian 36 niños, comprendidos entre 9 meses y 13 años, que fueron asistidos en el servicio de pediatría del Instituto de Gastroenterología, con el diagnóstico de enfermedad celíaca, a los que se les realizó biopsia de yeyuno, d-xylosa, van der Kamer y otros. Se señala la incidencia familiar, la asociación con la enteropatía exudativa y la frecuencia con que encontramos pie plano; se insiste en que nuestro medio la regresión histológica, con la supresión del gluten de la dieta, no siempre se observa en los estudios evolutivos, debido al mal manejo dietético en el medio familiar(AU)
