RESUMO
Background: Food proteininduced allergic proctocolitis (FPIAP) is characterized by bloody stools in well-appearing infants. Zinc is a micronutrient that plays a crucial role in immune modulation and is essential for cellular function during immune response. Although there are studies on the assessment of intracellular zinc levels in allergic diseases, no data is available on erythrocyte zinc levels of patients with FPIAP. Objective: This study aimed to assess the erythrocyte zinc levels of children with allergic proctocolitis and compare zinc levels with clinical and demographic characteristics. Methods: This was a casecontrol study that prospectively compared 50 patients with FPIAP and 50 healthy children without malnutrition. The erythrocyte zinc levels of children were determined using atomic absorption spectrophotometry. Results: Fifty patients with FPIAP, including 28 (51%) girls, with median age of 7.1 ± 2.9 (314) months and 50 healthy children, including 26 (53.1%) girls, with median age of 7.7 ± 2.8 (313) months were included in the study. Seventy percent (n = 35) of the patients with FPIAP started to have symptoms while they were exclusively breastfeeding. Offending allergen foods were cows milk (78%), egg (40%), sesame (10%), hazelnut (8%), almond (6%), beef (6%), and peanuts (6%, n = 3). Intracellular (erythrocyte) zinc levels in patients with FPIAP were lower than in the healthy control group (495.5 ± 134 µg/dL, 567.3 ± 154.4 µg/dL, respectively, P = 0.01). Patients with FPIAP aged younger than 6 months had lower intracellular zinc levels compared with those aged above 6 months (457 ± 137 µg/dL; 548 ± 112 µg/dL, respectively, P = 0.01). There was no relationship between zinc levels and time of symptom onset, presence of concomitant disease, being allergic to multiple foods, and family history of atopy (P > 0.05). Conclusions: FPIAP is a food allergy with limited information on its pathogenesis (AU)

Diversion colitis is a non-specific inflammation of a defunctionalised segment of the colon after a temporary stoma has been performed. This inflammation is associated with an alteration of certain inflammatory serum markers. The aims of this study were, firstly, to evaluate the modification of inflammatory biomarkers after stimulation with probiotics prior to closure of the protective ileostomy. Secondly, to identify if a relationship could be established between the severity of diversion colitis and the alteration of inflammatory biomarkers in the blood. A prospective, randomized, double-blind, controlled study was conducted. Patients who underwent surgery for colorectal carcinoma with protective ileostomy between January 2017 and December 2018 were included, pending reconstructive surgery and with diversion colitis as diagnosis. The sample was randomly divided into a group stimulated with probiotics (SG) (n = 34) and a control group (CG) (n = 35). Histological and endoscopic changes were evaluated after stimulation, after restorative surgery and during the short-term follow-up after surgery, including the correlation with pro-inflammatory biomarkers in blood. As main findings, a significant decrease in C-reactive protein (CRP), Neutrophil/lymphocyte ratio (NLR ratio), and monocyte/lymphocyte ratio (LMR ratio) was observed in the SG versus the CG with a p < 0.001. A significant increase in transferrin values and in the platelet/lymphocyte ratio (PLR) was observed in the SG versus CG after stimulation with probiotics with a p < 0.001. A normalisation of CRP and transferrin levels was observed in the third month of follow-up after closure ileostomy, and NLR, LMR and PLR ratios were equal in both groups. Decreased modified Glasgow prognostic score was found in SG compared to CG after probiotic stimulation (p < 0.001). The endoscopic and histological severity of diversion colitis is associated with a greater alteration of blood inflammatory biomarkers. The stimulation with probiotics prior to reconstructive surgery promotes an early normalization of these parameters.

Antecedentes: Con el incremento de la proctocolitis alérgica inducida por proteínas de la dieta (PAIPD), son necesarios estudios que aclaren su fisiopatología y determinar marcadores no invasivos y sencillos para el diagnóstico y la evaluación del desarrollo de tolerancia. No hallamos estudios publicados sobre la función del índice de neutrófilos/linfocitos (INL) y el volumen plaquetario medio (VPM), que son marcadores no invasivos fácilmente medibles, en pacientes con PAIPD. Objetivos: Determinar la relación entre el INL y el VPM con el diagnóstico y desarrollo de tolerancia en niños con PAIPD. Métodos: Estudio transversal retrospectivo, los datos se obtuvieron del sistema de registros médicos, los síntomas y los resultados de laboratorio de los pacientes con diagnóstico de PAIPD fueron controlados en los consultorios de alergia y gastroenterología. Se compararon valores del hemograma al momento del diagnóstico con el grupo de niños sanos de edad y sexo similares. Resultados: Entre los 59 pacientes con diagnóstico de PAIPD, los varones representaron el 47,4% y las niñas, el 52,6%. El VPM y el volumen plaquetario relativo (VPR) eran significativamente más altos entre los pacientes con PAIPD en comparación con el grupo de referencia (n: 67) (p < 0,001). Asimismo, VPM y el VPR fueron significativamente elevados en pacientes que no desarrollaron tolerancia comparados con los que la desarrollaron (p= 0,01). Con el INL no hubo diferencias entre los grupos. Conclusiones: El VPM y el VPR se consideraron marcadores adecuados para predecir el pronóstico de los pacientes con PAIPD dado que son rápidos, costo-efectivos y fáciles de medir.
Background. Today, as a result of an increase in the frequency of food protein-induced allergic proctocolitis (FPIAP), there is a need for studies not only to enlighten the pathophysiology of the disease but also to determine simple, non-invasive markers in both diagnosis, and evaluation of the development of tolerance. No study has been found in the literature about the place of neutrophil/lymphocyte ratio (NLR) and mean platelet volume (MPV), which are easy to calculate and non-invasive markers. Objectives. The purpose is to determine the relation between NLR and MPV with the diagnosis and development of tolerance in children with FPIAP. Methods. In this retrospective cross-sectional study, clinical, demographic symptoms and laboratory findings of patients, monitored with FPIAP diagnosis in allergy and gastroenterology clinics, were acquired from the patient record system. Hemogram values at the time of diagnosis were compared with the values of healthy children of the same age and gender. Results. Among 59 patients diagnosed with FPIAP, males constitute 47.4% and females constitute 52.6%. MPV and platelet crit (PCT) values were significantly high when compared to the control group (n: 67) in FPIAP cases (p <0.001). Also, MPV and PCT values were significantly high in non-tolerance developing cases when compared to developing ones (p= 0.01). Conclusions. Contrary to NLR, MPV and PCT values have been considered to be good markers in predicting prognosis in cases with FPIAP since they are quick, cost effective and easy to calculate.

BACKGROUND: Some infants with food protein-induced enterocolitis syndrome (FPIES) have increased serum C-reactive protein (CRP) and fever in Japan. The aim of this study was therefore to clarify and compare the incidence of this in patients with FPIES versus patients with food protein-induced proctocolitis (FPIP). METHODS: One hundred and sixteen infants with non-IgE-mediated gastrointestinal food allergies were enrolled in this study and classified into three phenotypes: FPIES presenting with vomiting and/or diarrhea (n = 47); FPIP with bloody stool alone (n =19); and the mixed phenotype (MP), bloody stool with vomiting and/or diarrhea (n = 50). RESULTS: Serum CRP was increased in 55.3% of the FPIES group, similar to that in the MP group (54.0%), and significantly higher than in the FPIP group (15.8%; P < 0.01). Fever was observed in 29.8% of the FPIES group, significantly higher than in the MP group (8.0%; P < 0.01) and in the FPIP group (0%; P < 0.05). Patients with fever had significantly higher serum CRP than patients without fever (median, 12.8 vs <0.2 mg/dL, P < 0.00001). CONCLUSIONS: Serum CRP was significantly higher in the FPIES group than in the FPIP group. This suggests that serum CRP is a useful marker for differentiating the pathogenesis of FPIES from FPIP. From the perspective of serum CRP, the pathology of the intestinal inflammation in MP subjects is suggested to be similar to that of FPIES.

OBJECTIVES: The dietary protein proctocolitis, also known as allergic proctocolitis (AP), is characterized by the presence of mucoid, frothy, and bloody stools in an otherwise healthy infant. The aim of this study was to describe a group of children with AP, diagnosed according to the criterion-standard method, food challenge to provide clinicians with more information on typical presentation, and an overview on nutritional management strategies and prognosis. METHODS: We collected data on infants with AP in our allergy and gastroenterology outpatient clinics. Any other conditions that may cause bloody diarrhea were ruled out. Skin prick tests and atopy patch tests were performed for diagnosis, and patients were studied for resolution. To the patients whose rectal bleeding did not recover with oligoantigenic maternal diet in addition to amino acid-based formula, endoscopic evaluation was performed to confirm the diagnosis and to exclude other reasons of rectal bleeding. RESULTS: Sixty patients were diagnosed as having AP. The age of onset was 1.7â±â1.32 months. All of the patients were triggered by milk, 6.6% with milk and egg, 3.3% with milk and chicken, 1.7% with milk and wheat, 1.7% with milk and potato, and 3.3% had multiple food allergy. 53.3% (nâ=â32) acquired tolerance by age 1, 25.0% (nâ=â15) by 2 years, 5% (nâ=â3) by 3, and 1.7% (nâ=â1) by 4 years. CONCLUSIONS: Milk was a triggering factor for all of the patients. Resolution of AP is usually within 1 year but symptoms of some patients may continue even longer. An extension of the follow-up period is required according to our study.

BACKGROUND: Although rectal bleeding in infancy (RBI) is not a rare phenomenon, the clinical course of RBI is not fully understood. METHODS: To investigate the outcome and pathogenesis of RBI, especially when concomitant with food-protein-induced proctocolitis (FPIP) and neonatal transient eosinophilic colitis (NTEC), 22 neonates with rectal bleeding with FPIP and NTEC from January 2008 to June 2012 were enrolled and their clinical course and mechanisms of inflammation were examined. RESULTS: Thirteen infants showed rectal bleeding after feeding and were diagnosed with FPIP, and nine infants showed rectal bleeding before feeding and were diagnosed with NTEC. Elevated peripheral white blood cell (12,685 ± 3754/µl and 30,978 ± 16,166/µl) and eosinophil (1084 ± 816/µl and 4456 ± 3341/µl) were confirmed in FPIP and NTEC, respectively. Colonoscopy revealed nodular lymphoid hyperplasia, a pale mucosal surface and oozing with diffuse infiltration of neutrophils, lymphocytes, and eosinophils in both groups. Reverse transcription polymerase chain reaction analysis revealed enhanced expression of the interleukin-6, CCL11, and CXCL13 genes, where CXCL13 expression was more prominent in FPIP. Mucosal infiltration by CD3- and immunoglobulin-A- but not immunoglobulin-E-positive cells was confirmed. Among them, only one infant with FPIP developed milk allergy, whereas none with NTEC had developed milk allergy at the age of 1 year. CONCLUSIONS: FPIP in infancy and NTEC are similar diseases and interleukin-6, CCL11, and CXCL13 may play a major role in the pathogenesis of rectal bleeding. Although the involvement of allergic reaction is possible, milk allergy was not a common outcome after 1 year of follow up.

BACKGROUND: The serum markers ASCA and pANCA can help the clinician in certain difficult situations of colites in IBD. The aim of this study was to determine the sensitivity and the specificity of each one of these markers and to establish the characteristics of the positive patients for each one. METHODS: We included patients having a Crohn's disease (CD) or an ulcerative colitis (UC). These patients was compared to a control group. RESULTS: 80 CD patients with an average age of 35.62 years, 25 UC cases with an average age of 34.92 years and 79 healthy subjects with an average age of 34.2 years were included. The ASCA were detected in 33.8% of CD cases , 8% of UC cases of RCH and 2.5% of contro group (p < 000.1). The pANCA were detected in 48% of UC cases, 27.5% of CD patients and 1.3% of controls (p < 000.1). The sensitivity and the specificity of the ASCA and the pANCA for the diagnosis respectively of CD and UC were 33.8%, 97.5% and of 48%, 97.8%. During the CD, the positivity of the ASCA was significantly associated with ileal location (p = 0.001), with the sténosant and/or fistulisant phenotyp of the disease (p = 0.006), the young age at the time of the diagnosis of the CD (p = 0.067) and at a greater frequency of surgical treatment (p = 00.7). The pANCA were more frequently found in colic location of CD (p = 0.09). During UC, the positivity of the pANCA was not associated with the sex, age, loca tion of the disease, medical treatment nor chiurgical treatment. CONCLUSION: The ASCA and pANCA are useful during some clinical situations such as differentiation between IBD otherss colitis and to distinguish CD from UC.

We estimated the extent of the inflammatory mucosal lesion by colonoscopy and biopsy in 60 patients with their first attack of ulcerative colitis. Proctitis was found in 12, proctosigmoiditis in 19, left-sided colitis in 10, and extensive colitis in 19. Fourteen clinical variables and laboratory measurements (bowel frequency, stool consistency, rectal bleeding, fecal mucus/pus, temperature, pulse rate, white blood cell count, hematocrit, sedimentation rate, serum iron, serum albumin, serum alpha 2-globulin, serum C-reactive protein, and seromucoids) were determined. All the variables except rectal bleeding and hematocrit were correlated (p less than 0.001) with the extent of colitis. On stepwise discriminant analysis, only C-reactive protein distinguished proctosigmoiditis from more improved the discrimination. Cross-validation by the "jack-knife method" showed that 86.7% of patients were correctly classified, the errors consisting in underestimation of disease in 8/29 patients with extensive colitis.

To assess the reliability of the erythrocytic sedimentation rate (ESR) as a measure of clinical activity in inflammatory bowel disease, we analyzed the correlations of ESR with a global assessment of clinical activity in 77 patients with varying extents of Crohn's disease and ulcerative colitis. Analysis of all 141 ESR determinations in all 77 patients showed a highly significant correlation between mean ESR and clinical activity score (r = 0.54, p less than 0.001). Analysis of 133 ESR determinations in these 77 patients when their disease activity was either mild, moderate, or severe showed some significant differences among certain disease categories. The highest mean ESRs were in patients with the most extensive colon involvement (Crohn's colitis 40.7 +/- 3.3, universal ulcerative colitis 31.0 +/- 3.9), whereas the lowest mean ESRs were in patients with the most limited disease (ulcerative proctitis and proctosigmoiditis 19.2 +/- 2.1). The rate of increase in ESR with progressively increasing clinical activity from mild to moderate was the same in all disease categories, with the exception of Crohn's disease limited to the small bowel (ileitis or jejunoileitis), in which the ESR was relatively unchanged in a small sample of patients. By the time clinical activity became severe, however, patients in all disease categories manifested similarly high ESRs, with the exception of ulcerative proctitis in which the ESR remained low in the single patient tested.(ABSTRACT TRUNCATED AT 250 WORDS)

Plasma prednisolone levels have been compared in healthy volunteers and in patients suffering from idiopathic proctocolitis after the administration of standard retention enemata containing either prednisolone-21-phosphate or prednisolone metasulphobenzoate sodium. The levels were significantly lower after the latter, irrespective of the presence or degree of activity of the disease. Prednisolone metasulphobenzoate appeared to be as effective as the 21-phosphate ester for the treatment of proctocolitis in the few patients where the two drugs were compared. It seems possible that the beneficial effect of the form of therapy is exerted predominantly locally, rather than by systemic action.

Plasma prednisolone levels have been measured by radioimmunoassay after oral and rectal administration to healthy volunteers and to patients with idiopathic proctocolitis. The amount of prednisolone absorbed from a 20 mg retention enema given to patients with proctocolitis was about 44% of that absorbed from the same dose orally administered. Adrenocortical response to synthetic ACTH in patients receiving prolonged rectal therapy was either normal, or only slightly impaired, and this may be related to the pattern of steroid absorption rather than to the total amount absorbed.

The faecal output of chloride, sodium and potassium was studied in 14 patients with active idiopathic proctocolitis, in an attempt to establish a relationship between faecal electrolyte output and acid-base balance data. 7 patients with ileostomy and 8 healthy volunteers were used as controls. The daily faecal excretion of chloride and sodium in proctocolitis was significantly in excess of normal, whereas that of potassium was within the normal range. From the comparison with the results in patients with ileostomy it is concluded that colitic colon has an impaired capacity to absorb chloride and sodium but retains the ability to secrete potassium. The intestinal loss of chloride in addition to that of sodium and water may be regarded as a salt-losing diarrhoea and may account for the metabolic alkalosis commonly found in proctocolitis.

Acid base balance was studied in 58 patients with active idiopathic proctocolitis; the condition of 10 of them was complicated by toxic megacolon. Arterial blood pH increased progressively with increased severity of the colitis and as the lesions became more widespread. Statistically significant differences were observed in pH values between the mild/moderate and severe forms and between the severe and complicated forms ('toxic megacolon'). A linear correlation was found between pH and the amount of intestinal gas, pulse rate, and plasma albumin.
