AIMS: The primary aim was to assess whether there were differences in symptoms, laboratory data, and oesophageal pH-metry between infants with primary gastro-oesophageal reflux and those with reflux ...secondary to cows' milk protein allergy (CMPA). PATIENTS AND METHODS: 96 infants (mean(SD) age 7.8(2.0) months) with either primary gastro-oesophageal reflux, reflux with CMPA, CMPA only, or none of these (controls) were studied. Symptoms, immunochemical data, and oesophageal pH were compared between the four groups and the effect of a cows' milk protein-free diet on the severity of symptoms was also assessed. RESULTS: 14 out of 47(30%) infants with gastro-oesophageal reflux had CMPA. These infants had similar symptoms to those with primary gastro-oesophageal reflux but higher concentrations of total IgE and circulating eosinophils (p < 0.005) and IgG anti-beta lactoglobulin (p < 0.003). A progressive constant reduction in oesophageal pH at the end of a feed, which continued up to the next feed, was seen in 12 out of 14 patients with gastro-oesophageal reflux secondary to CMPA and in 24 of 25 infants with CMPA only. No infants with primary gastro-oesophageal reflux and none of the controls had this pattern. A cows' milk protein-free diet was associated with a significant improvement in symptoms only in infants with gastro-oesophageal reflux with CMPA. CONCLUSION: A characteristic oesophageal pH pattern is useful in distinguishing infants with gastro-oesophageal reflux associated with CMPA.
Non-celiac wheat sensitivity (NCWS) is a new clinical entity in the world of gluten-related diseases. Nickel, the most frequent cause of contact allergy, can be found in wheat ...and results in systemic nickel allergy syndrome and mimics irritable bowel syndrome (IBS). Objective: To evaluate the frequency of contact dermatitis due to nickel allergy in NCWS patients diagnosed by a double-blind placebo-controlled(DBPC)challenge,and to identify the characteristics of NCWS patients with nickel allergy. Methods: We performed a prospective study of 60 patients (54 females, 6 males; mean age 34.1 ± 8.1 years) diagnosed with NCWS from December 2014 to November 2016; 80 age- and sex-matched subjects with functional gastrointestina l symptoms served as controls. Patients reporting contact dermatitis related to nickel-containing objects underwent nickel patch test (Clinicaltrials.gov registration number: NCT02750735).
Six out of sixty patients (10%) with NCWS suffered from contact dermatitis and nickel allergy and this frequency was statistically higher (p = 0.04)than observed in the control group(5%. The main clinical characteristic of NCWS patients with nickel allergy was a higher frequency of cutaneous symptoms after wheat ingestion compared to NCWS patients who did not suffer from nickel allergy (p < 0.0001.
Contact dermatitis and nickel allergy are more frequent in NCWS patients than in subjects with functional gastrointestinal disorders;furthermore, these patients had a very high frequency of cutaneous manifestations after wheat ingestion. Nickel allergy should be evaluated in NCWS patients who have cutaneous manifestations after wheat ingestion.

In an open study of children with chronic constipation, we recently demonstrated that constipation may be a symptom of intolerance of cow's milk. . . .
Background
Recent research has shown that cow's milk protein intolerance (CMPI) often persists beyond 4 years of age.
Aims
To evaluate the clinical and immunological characteristics of a group of ...infants with persistent CMPI.
Patients and methods
Twelve infants (6 m, 6f) with persistent CMPI were followed up from birth until a median age of 5 years. The patients underwent CMP challenge each year to evaluate CMP‐tolerance. As controls we followed 26 infants (12 m, 14 f) with CMPI that resolved within 1–2 years.
Results
A family history of atopic disease was found in 10/12 patients with persistent CMPI and in 10/26 controls (P < 0.01). Clinical presentation changed over time: at onset symptoms were prevalently gastrointestinal, while at the end of the study there was an increased frequency of wheezing and constipation and a higher frequency of delayed reactions to CMP‐challenge than at study commencement (9/12 vs 2/12; P < 0.007). 11/12 infants with persistent CMPI and 3/26 controls (P < 0.0001) presented multiple food intolerance. During the observation period 9/12 infants with persistent CMPI and 2/26 controls showed atopic disease: asthma, rhinitis, eczema (P < 0.0001).
Conclusions
Persistent CMPI forms are characterized by: (a) considerable importance of familial atopic disease; (b) change in CMPI manifestations over time and more prolonged delay between CMP consumption and manifestation of symptoms; (c) very high frequency of multiple food intolerance and allergic diseases.

BACKGROUND & AIMS: Clinical significance and duration of insufficient release of pancreatic enzymes in childhood celiac disease have not been clarified. The aim of this study was to evaluate the role ...that pancreatic impairment plays in growth recovery and the duration of this impairment. METHODS: Forty-six patients with celiac disease who had a median age of 2.5 years were enrolled. Fecal chymotrypsin level was determined at diagnosis and then every 15 days after the beginning of a gluten-free diet in all patients. RESULTS: At diagnosis, 17 of 46 patients with celiac disease had subnormal fecal chymotrypsin values. During the gluten-free diet, a progressive reduction in the percentage of patients with subnormal fecal chymotrypsin values was observed: 12 of 46 patients after 30 days and 2 of 46 patients after 60 days. Weight increase after 2 months of gluten-free diet was significantly greater in patients with normal fecal chymotrypsin values at diagnosis than in patients with subnormal values, and a positive correlation was found between fecal chymotrypsin at diagnosis and weight increase (r = 0.56). CONCLUSIONS: A small percentage of patients with celiac disease still had subnormal chymotrypsin concentrations after 60 days of gluten-free diet. Fecal chymotrypsin is a predictive index of weight recovery in the first months after diagnosis of celiac disease; it could be used to select patients for enzyme supplementation therapy.

We report a study of realimentation techniques in 9 unweaned infants with multiple food hypersensitivity. The patients had presented severe symptoms of cowʼs milk allergy and successive attempts ...using milk containing soy protein and/or a semielemental formula in their alimentation did not improve their clinical condition, due to the onset of hypersensitivity to these allergens as well. After a short period of parenteral alimentation the infants were refed per os with assʼ milk (250 ml/kg/day) + medium chain triglycerides (40 ml/L milk). This food was well tolerated by all patients. No negative clinical reactions were recorded and during hospitalisation average weight increase was 39.8 g/day. The follow-up of the patients showed that assʼ milk was tolerated without any problems up to an age ranging from 15 to 20 months, when cowʼs milk was reintroduced in some patients.
With the widespread use of ultrasonography (US) and computerized tomography (CT), the usefulness of alpha-fetoprotein assay in the diagnosis of hepatocellular carcinoma (HCC) has decreased. The aim ...of our study was to evaluate the best cut-off value for serum alpha-fetoprotein to discriminate between liver cirrhosis (LC) and HCC and the factors influencing levels in a Sicilian population. Three hundred and seventy-two patients with LC and 197 with HCC-associated LC were studied. The etiology was: HCV in 288 cases (77.4%) of LC and 147 cases (75%) of HCC; HBV in 31 cases (8.3%) of LC and 15 cases (7.6%) of HCC; HCV/HBV in 21 cases (5.6%) of LC and 6 cases (3.0%) of HCC; non-viral in 32 cases (8.6%) of LC and 29 cases (15%) of HCC. Hepatic function was estimated by the Child-Pugh's score; the TNM classification was used in HCC. The area under the ROC curve was 0.81 +/- 0.02; the best discriminant cut-off value, calculated as the value of the maximized likelihood ratio, was 30 ng/ml. At this level sensitivity (SE) was 65%, specificity (SP) 89%, positive predictive value (PPV) 74% and negative predictive value (NPV) 79%. When the patients were divided at this cut-off point into two groups according to viral or non-viral etiology, PPV was 70% versus 94%, respectively (p < 0.05). In the non-viral diseases PPV reached 100% for AFP serum levels of 100 ng/ml, while in the viral diseases PPV was 100% when AFP was greater than 400 ng/ml. There were no significant differences in SE, SP or NPV between viral and non-viral liver diseases. Child's classes B and C were more frequent in HCC (chi 2 of MH 7.7, p < 0.0001). There was a correlation between AFP serum values and TNM classification (p < 0.02) and on multiple logistic regression AFP levels > 30 ng/ml correlated positively only with the TNM stage (p < 0.0001). In conclusion, the best cut-off value for serum AFP in our study population was 30 ng/ml, but at this level sensitivity was low. This cut-off value was more useful in detecting non-viral HCC, because PPV was significantly higher than in viral HCC; therefore, our data confirm that the usefulness of AFP in the diagnosis of HCC of viral etiology is limited, being more useful in HCC of non-viral etiology.
