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.

Background:Gastrointestinal (GI) involvement is very common in patients with Systemic Sclerosis (SSc). The pathophysiology of GI manifestations has not yet been defined. Cell-mediated immunological reactions appear to lead to endothelial damage resulting in fibrosis. The risk of developing malnutrition reinforces the need to better understand GI pathophysiology in these patients.Objectives:The study aimed to evaluate GI symptoms (GIT 2.0) and malnutrition status (MUST) and to determine specific bacterial changes in gut microbiome by investigating the possible presence of positive hot spots in bacterial species in SSc patients and their potential role in the disease progression. We also evaluated serum levels of adipokines and cytokines involved in the pathogenesis of SSc and their role, in addition to gut microbiome, in predicting the onset of GI involvement and malnutrition in SSc patients.Methods:We enrolled 25 scleroderma patients (EULAR/ACR 2013 criteria). UCLA-SCTC GIT 2.0 questionnaire to evaluate GI symptoms and MUST to investigate the risk of malnutrition were used. Gut microbiome was analyzed and the samples were subjected to extraction for the 16S rRNA gene (Earth Microbiome Project and the NIH-Human Microbiome Project). The microbiome was investigated at phenotypic and genotypic level. Serum levels of cytokines and adipokines (adiponectin and leptin) were evaluated by ELISA.Results:79.9% of patients had GERD and 63.5% abdominal distension at GIT 2.0 questionnaires. 48% of patients had moderate risk of malnutrition (MUST=2) and 12% had high risk (MUST=3). Gut microbioma: 19 patients (76%) had low similarity and 11 (44%) low diversity compared to the healthy population. The prevailing enterotypes of gut microbiome was Bacteroides (80%) and Prevotella (20%). The genotypic evaluation showed a reduced concentration of: gluten-digesting (Lactobacillus); lactose-digesting (Faecalibacterium); vitamin K-producing (Enterococcus, Desulfovibrio and Veillonella); acetaldehyde-degrading bacteria. 24 patients (96%) showed a reduction in bacteria devoted to maintaining weight control (Bifidobacterium and Ruminococcus). The patients had an altered intestinal permeability with less mucolytic bacteria (Bacteroides) and reduced production of LPS (Enterobacter and Escherichia). Low levels of butyrate (Eubacterium and Clostridium), acetate and propionate were found for SCFA-producing bacteria. Potentially pathogenic bacteria were also investigated: Salmonella was found in 14 (56%), Klebsiella in 9 (36%) and Enterococcus Faecalis in 3 (12%) patients. 11 (44%) patients had elevated serum levels of IL10 and IL12; 4 (16%) had high value of leptin. Correlation was found in patients who had a reduced concentration of gluten-digesting bacteria and MUST. Elevated MUST was correlated with serological increase in IL17A and IFN-α. Serum levels of IL12 and IL10 were found to correlate with specific bacteria alterations: high concentration of acetaldehyde-producing bacteria and low levels of acetaldehyde-degrade bacteria (also correlated with high serum levels of IL6), mucolytic bacteria and producers of hydrogen sulphide, acetate and propionate. Finally, reduced levels of mucolytic bacteria and acetate producing bacteria correlated with high serum leptin levels.Conclusion:The relationship between the gut microbiome and SSc seems to be multifactorial. In our study genotypic changes of gut microbioma might play a role in damaging the permeability of the mucosa and increasing risk of malnutrition. The evaluation of gut microbiome and cytokine profile is probably going to be of value in the follow-up of SSc. However, further studies are needed to clarify the impact of GI dysbiosis on the immune system in SSc.References:[1]Patrone V. et al.

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 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 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.

Brucellosis is a systemic zoonotic infectious disease that may cause fever, fatigue, sweating, arthritis, hepatosplenomegaly, cytopenia, and lymphadenopathy. It continues to be an important health problem worldwide. Hemophagocytic lymphohistiocytosis (HLH) is characterized by fever, hepatosplenomegaly, cytopenias, high serum levels of ferritin and triglycerides, low serum fibrinogen levels, and hemophagocytosis in bone marrow, lymph nodes, spleen, or liver. Hemophagocytic lymphohistiocytosis associated with brucellosis is a very rare condition in the pediatric age group. Here, three pediatric cases of secondary HLH associated with brucellosis are reported. Hemophagocytic lymphohistiocytosis should be considered in patients with brucellosis having cytopenias. Hemophagocytosis in brucellosis seems to be cured with appropriate antibiotics and intravenous immunoglobulin.

Abstract Low serum levels of vitamin D are associated with a higher frequency of at least eleven different malignancies including breast, colon, and prostate cancer (Holick, M.F. Vitamin D: Millenium Perspective. Journal of Cellular Biochemistry. 2003. 88:296–307). Low levels of vitamin B12 were found to contribute to a 2.5–4.0 times greater likelihood of breast cancer in postmenopausal women (Wu, K. et al. Cancer Epidemiol. 1999. 8:209–17) and hematological and mucosal tissue is more sensitive to chemotherapy in the presence of insufficient levels of B12. Only vitamin B12 that is complexed to transcobalamin as holotranscobalamin (HTCII) is metabolically active. It has been suggested that decreased HTCII serum levels are involved in the failure to methylate DNA resulting in the activation of oncogenes that would normally be dormant (Herbert, V. Methyl Metabolism: Epigenetics, Genomics, Proteomics. 2002 FASEB Summer Research Conference. Snowmass Village, Colarado.).Our study investigated vitamin D, total B12 and HTCII levels in 70 cancer patients. Vitamin D was measured as serum 25 OH-D3 (Nichols Advantage assay) and serum B12 was measured as both total B12 and as the metabolically active HTCII (Immulite B12 assay followed by glass adsorption: Vu, T. et al., Am J. Heme42: 202–211 1993). Vitamin D insufficiency has been defined based on differing physiologic sequelae of insufficiency and varies between values less than 50–75 nMol/L. When vitamin D insufficiency is defined as serum level <75nmol/L, 43 of 60 (72%) of cancer patients were found to be insufficient. At a lower definition of insufficiency, <50nmol/L, 24 of 60 patients (40%) were insufficient. Of 52 patients, only 3 (6%) were found to have insufficient serum levels of total B12 (normal >300pg/mL) while 17 of 52 (34%) were found to be HTCII insufficient (normal >69 pg/mL). Of these 17 patients, 14 (84.4%) had normal total B12 levels. Low levels of vitamin D strongly correlated with low serum HTCII. All 12 HTCII deficient patients were vitamin D insufficient at the <75nmol/L standard. Six of 12 HTCII deficient patients (50%) were vitamin D deficient at the <50nmol/L cut off. Chi-squared test for independence revealed a strong relationship between low levels of vitamin D and HTCII. Deficiency of vitamin D (70%) and holotranscobalamin (34%) is prevalent among newly diagnosed patients with cancer. The standard measurement of total serum B12 alone is inadequate for identifying patients with insufficient levels of metabolically active B12. Low vitamin D and holotranscobalamin levels may play a role in cancer development, progression and host response to tumor and therapy. Possible explanations for combined HTCII and D3 deficiency include age, the presence of atrophic gastritis in 30–50% of the elderly, and lack of sun exposure and deficient production of D3 in the elderly. Since both vitamins are conserved by cubulin/megalin mediated renal tubular reabsorption a defect of this mechanism could contribute to deficiency of both vitamins.

Insulin-like growth factor-1 (IGF-1) and growth hormone (GH) levels are the main targets for monitoring acromegaly activity, but they are not in close relationship with the clinical course of the disease and the associated comorbidities. The present study was aimed at identifying metabolites that could be used as biomarkers for a better disease phenotyping. For this purpose, metabolic fingerprint using an untargeted metabolomic approach was examined in serum from 30 patients with acromegaly and 30 age-matched controls. Patients with acromegaly presented fewer branched-chain amino acids (BCAAs) compared to the control group (valine: 4.75 ± 0.87 vs. 5.20 ± 1.06 arbitrary units (AUs), p < 0.05; isoleucine: 2.54 ± 0.41 vs. 2.80 ± 0.51 AUs; p < 0.05). BCAAs were also lower in patients with active disease compared to patients with normal levels of IGF-1 with or without medical treatment. GH, but not IGF-1, serum levels were inversely correlated with both valine and isoleucine. These findings indicate that low levels of BCAAs represent the main metabolic fingerprint of acromegaly and that GH, rather than IGF-1, might be the primary mediator. In addition, our results suggest that the assessment of BCAAs could help to identify active disease and to monitor the response to therapeutic strategies.

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.
