Aim To assess the possible relationship between serum alpha-1 antitrypsin (AAT) levels and anti-neutrophil cytoplasmic antibodies (ANCA) in autistic children with severe GI disease and to test the hypothesis that there is an association between low serum AAT levels, the presence of ANCA and inflammatory GI disease seen in some autistic children. Subjects and Methods Serum from 40 autistic children with chronic digestive disease (many with ileo-colonic lymphoid nodular hyperplasia (LNH) and inflammation of the colorectum, small bowel and/or stomach), and 41 controls (21 age matched autistic children with no GI disease and 20 age matched children without autism or GI disease) were tested using ELISAs designed to quantitate ANCA (anti-PR3), AAT and PR3 levels. Results We found that a significant number of autistic children with chronic digestive disease had anti-PR3 ANCA, high serum PR3 and high severity of disease when compared to controls. This same group of autistic children had low serum levels of AAT compared to controls, which also correlated with the presence of anti-PR3 ANCA, high serum PR3, as well as the severity of intestinal disease, particularly LNH and severe erythema. Discussion These results suggest a relationship between low AAT levels, ANCA and severity of GI disease seen in a subpopulation of ASD individuals. We suggest that low AAT levels may result in high levels of PR3, which may, in turn be associated with the presence of ANCA.

Aim To assess serum Cu/Zn SOD (Superoxide Dismutase) concentration in autistic children and evaluate its possible relationship to GI Symptoms. Subjects and Methods Serum from 50 autistic children (31 with chronic digestive disease (most with ileo-colonic lymphoid nodular hyperplasia (LNH) and inflammation of the colorectal, small bowel and/or stomach) and 19 autistic children without GI disease), and 29 non autistic controls (20 age matched non autistic children with no GI disease and 9 age matched non autistic children with GI disease) were tested for Cu/Zn SOD using ELISAs. Results Serum Cu/Zn SOD levels of autistic children were significantly lower than all non autistic controls (p < 0.0001). Serum Cu/Zn SOD of autistic children with severe GI disease was significantly lower than autistic children with no GI disease (p < 0.0001), non autistic children without GI disease (<0.0001) and non autistic children with GI disease (p = 0.0003). Discussion These results suggest an association between Cu/Zn SOD serum levels and autism, particularly autistic children with GI disease, and that the concentration of serum Cu/Zn SOD may be a useful biomarker for autistic children with severe GI disease.

Aim Deficiency of Alpha-1-antitrypsin (AAT) can be a genetic condition that increases the risk of developing liver, lung and possibly gastrointestinal disease. Since many autistic children also have gastrointestinal disorders, this study was designed to measure serum concentration of AAT and establish AAT genotypes in autistic children, age and gender matched non-autistic siblings, parents and controls. Subjects and Methods We used an indirect ELISA with monoclonal IgG to AAT to measure AAT serum concentrations in 71 members from 16 families of individuals with autism and 18 controls (no family history of autism). We used a duplex polymerase chain reaction to detect M, S and Z alleles for alpha-1 antitrypsin expression in 52 members of 12 of the above families. Results A significantly high number of autistic family members had lower than normal serum levels of AAT when compared to controls. Autistic children with regressive onset had significantly lower levels of AAT compared to controls, and a significant number of autistic children with low serum AAT also had hyperbilirubinemia, gastrointestinal disease and respiratory problems. We also found that a significantly high number of these individuals had the PiMZ genotype and correspondingly low levels of serum alpha-1 antitrypsin. Discussion Knowing that low levels of alpha-1 antitrypsin may be inherited, and that low levels of AAT may be associated with GI disease in autistic children, genotyping autistic children may help identify individuals susceptible to developing digestive problems.

Abstract. Serum levels of thyroxine, 3,5,3'-triiodothyronine (T3), 3,3',5'-triiodothyronine (rT3), 3,3'-diiodothyronine (3,3'-T2), 3',5'-diiodothyronine (3',5'-T2) and TSH were measured in two clinical situations which are both known to induce a low serum T3 high serum rT3 syndrome: 1) during the early course of acute myocardial infarction (AMI) and after recovery, and 2) before and during one week's propranolol medication (20 mg 4 times a day). In 10 patients with AMI serum levels of the iodothyronines were unchanged on admission to hospital (in average 6.6 h after onset of symptoms). However, already 24 h after onset of symptoms serum T3 and 3,3'T2 were reduced whereas serum rT3 and 3',5'-T2 were increased. Serum T3 and 3,3'-T2 reached a nadir on day 4 and 3, respectively, whereas serum rT3 and 3',5'-T2 reached peak values 24 h after onset of symptoms. In eight healthy, euthyroid volunteers propranolol medication induced similar changes in iodothyronine concentration as AMI did. However, the alterations were more delayed. Serum T3 decreased slowly reaching statistically significantly reduced values on day 7. Serum rT3 and 3',5'-T2 were significantly enhanced from day 3 and 4, respectively. A close parallelism in alterations of serum T3 and 3,3'-T2 levels was observed. Our data suggest that T3 in the two situations studied is a major precursor for 3,3'-T2 probably as a consequence of reduced 5'-deiodinase activity. It seems possible that the mechanisms affecting the metabolism of the iodothyronines in AMI and during propranolol medication involved the same enzyme system. However, the late appearance of the alterations in serum iodothyronines levels during propranolol medication might indicate different modes of action.

Aim To assess serum Hepatocyte Growth Factor (HGF) levels in autistic children with severe gastrointestinal (GI) disease and to test the hypothesis that there is a relationship between GI pathology and HGF concentration. Subjects and Methods Serum from 29 autistic children with chronic digestive disease (symptoms for a minimum of 6–12 months), most with ileo-colonic lymphoid nodular hyperplasia (LNH—markedly enlarged lymphoid nodules) and inflammation of the colorectum, small bowel and/or stomach), and 31 controls (11 age matched autistic children with no GI disease, 11 age matched non autistic children without GI disease and 9 age matched non autistic children with GI disease) were tested for HGF using ELISAs. HGF concentration of autistic children with GI disease was compared to GI disease severity. Results Autistic children with GI disease had significantly lower serum levels of HGF compared to controls (autistic without GI disease; p = 0.0005, non autistic with no GI disease; p = 0.0001, and non autistic with GI disease; p = 0.001). Collectively, all autistic children had significantly lower HGF levels when compared to non autistic children (p < 0.0001). We did not find any relationship between severity of GI disease and HGF concentration in autistic children with GI disease. Discussion These results suggest an association between HGF serum levels and the presence of GI disease in autistic children and explain a potential functional connection between the Met gene and autism. The concentration of serum HGF may be a useful biomarker for autistic children, especially those with severe GI disease.

Abstract OBJECTIVE: It is unknown whether low serum levels of salivary and pancreatic amylases are associated with the high combustion of carbohydrates or lipids for energy. Elevated blood ketones and a low respiratory quotient (RQ) can reflect the preferential combustion of lipids relative to carbohydrates. Therefore, using the data from our previous study, we investigated if low levels of serum amylases were associated with a high serum ketone level and low RQ in 60 healthy non-obese young women aged 20–39 years old.RESULTS: Serum ketones [3-hydroxybutyric acid (3-HBA) and acetoacetic acid (AA)] were inversely correlated with RQs, but not body mass index (BMI) or glycated haemoglobin (HbA1c) levels. Logistic regression analysis showed that high levels of serum ketones (3-HBA ≥ 24 μmol/L and AA ≥ 17 μmol/L) and a low RQ (< 0.766) were significantly associated with low serum salivary (< 60 U/L) and pancreatic (< 29 U/L) amylase levels, respectively. These associations were not altered by further adjustments for age, BMI, HbA1c, and estimated glomerular filtration rate. These results confirm the high combustion of lipids for energy in individuals with low serum amylase levels, suggesting a close relationship between circulating amylases and internal energy production.

Elevated blood ketones and a low respiratory quotient (RQ) can reflect the preferential combustion of lipids relative to carbohydrates. Therefore, we investigated if low levels of serum salivary and pancreatic amylases were associated with a high serum ketone level and low RQ in healthy people. RESULTS Using the data from our previous study, we reanalysed clinical parameters, including serum salivary and pancreatic amylases, serum 3-hydroxybutyric acid (3-HBA) and acetoacetic acid (AA), and RQ in 60 healthy non-obese young women aged 20–39 years old. Serum ketones were inversely correlated with RQs, but not body mass index (BMI) or glycated haemoglobin (HbA1c) levels.

Abstract Background MicroRNA (miR)-217 is a tumor suppressor significantly associated with osteosarcoma. We try to evaluate serum levels miR-217 in osteosarcoma patients and evaluate its prognostic significance. Methods A total of 163 consecutive osteosarcoma patients and 96 healthy participates were enrolled. Serum miR-217 levels were evaluated by using real-time quantitative reverse transcription polymerase chain reactions(RT-PCR). The association between serum miR-217 level and survival outcomes was evaluated by univariate and multivariate analysis. Results Serum miR-217 levels in osteosarcoma patients was significantly lower than healthy volunteers (P<0.05). Low serum miR-217 was significantly related to advanced cancer and metastasis (both P<0.05). Moreover, patients with a low serum miR-217 had a poorer overall survival than those with a high serum miR-217 levels (P<0.05). Serum miR-217 level also been showed as independent risk factor for osteosarcoma in multivariate analysis (HR, 0.42; 95%CI: 0.12–0.98; p<0.01). Conclusions Serum miR-217 levels was significantly downregulated in osteosarcoma patients and remarkably associated with poor prognosis, indicating that serum miR-217 might serve as a useful diagnostic and prognostic indictor for osteosarcoma.

Immunohistochemical Finding

Hepatoid carcinoma is a rare ovarian tumor and is thought to be a histopathologic subtype different from hepatoid type yolk sac tumor based on its pathologic features. A 63-year-old woman who had postmenopausal bleeding and lower abdominal pain was found to have right ovarian mass on pelvic examination and computed tomography. She had high serum levels of alpha fetoprotein (AFP) and CA125. Histologically, the tumor resembled hepatocellular carcinoma by architectural and cytologic features. Immunohistochemically tumor cells were immunoreactive for AFP, alpha 1 antitrypsin, and carcinoembryonic antigens.

Alpha-fetoprotein (AFP) is a tumor marker routinely used for the diagnosis and follow-up of malignant neoplasms. We report a case of extremely high serum levels of AFP associated with benign lesions of the liver and of the lungs with a spontaneous and gradual drop to normal values in the 9-month follow-up without any form of treatment. As a result a high serum level of AFP does not necessarily indicate a malignant tumor and every patient presenting with such finding must be thoroughly examined before making a definitive diagnosis.
