Sample records for achlorhydria

  1. Calcium absorption and achlorhydria

    Defective absorption of calcium has been thought to exist in patients with achlorhydria. The author compared absorption of calcium in its carbonate form with that in a pH-adjusted citrate form in a group of 11 fasting patients with achlorhydria and in 9 fasting normal subjects. Fractional calcium absorption was measured by a modified double-isotope procedure with 0.25 g of calcium used as the carrier. Mean calcium absorption (+/- S.D.) in the patients with achlorhydria was 0.452 +/- 0.125 for citrate and 0.042 +/- 0.021 for carbonate (P less than 0.0001). Fractional calcium absorption in the normal subjects was 0.243 +/- 0.049 for citrate and 0.225 +/- 0.108 for carbonate (not significant). Absorption of calcium from carbonate in patients with achlorhydria was significantly lower than in the normal subjects and was lower than absorption from citrate in either group; absorption from citrate in those with achlorhydria was significantly higher than in the normal subjects, as well as higher than absorption from carbonate in either group. Administration of calcium carbonate as part of a normal breakfast resulted in completely normal absorption in the achlorhydric subjects. These results indicate that calcium absorption from carbonate is impaired in achlorhydria under fasting conditions. Since achlorhydria is common in older persons, calcium carbonate may not be the ideal dietary supplement

    Watery diarrhea, hypokalemia and achlorhydria (WDHA)syndrome caused by vasoactive intestinal polypeptide (VIP) -producing tumor only rarely occurs in patients with nonpancreatic disease. A 49-year-old woman was referred for evaluation of a right adrenal tumor incidentally diagnosed by abdominal ultrasound during the investigation of chronic watery diarrhea. Laboratory findings showed hypokalemia and excessive production of VIP and catecholamines. After surgical resection of the tumor, diarrhea subsided and both electrolytes and affected hormone levels normalized. Immunohistochemical examination confirmed a diagnosis of pheochromocytoma,which contained VIP-positive ganglion-like cells. We herein present the clinical and histogenetic implications of this rare clinical entity, with literature review.

  3. Gastric cancer risk in achlorhydric patients. A long-term follow-up study

    1986-01-01

    Achlorhydria, determined by the augmented histamine test, is the functional expression of the most severe atrophic gastritis and is followed by a 4- to 6-fold increased risk of gastric cancer, as we found 5 cancers in 114 patients after a mean observation period of 8.4 years. The cancers developed...... from 1 to 17 years after achlorhydria diagnosis--three cases after more than 9 years. The study showed no difference in gastric cancer risk between patients with and without pernicious anaemia. Spontaneous achlorhydria is the late result of atrophic gastritis, which should be regarded the premalignant...... condition. The development of gastric cancer from pharmacologically reduced acid secretion must be regarded as highly hypothetical, since this is not followed by atrophic gastritis....

    Autoimmune gastritis is characterised by lymphocytic infiltration of the gastric submucosa, with loss of parietal and chief cells and achlorhydria. Often, gastritis is expressed clinically as cobalamin deficiency with megaloblastic anaemia, which is generally described as a disease of the elderly. H

    It is still uncertain whether upper gastrointestinal bacterial overgrowth in patients with permanent achlorhydria causes malassimilation in more than just the occasional case. In an attempt to clarify this, 19 patients with pernicious anaemia who had undergone a thorough investigation 6.6 y (mean) previously, were reinvestigated with clinical history, upper GI endoscopy including multiple duodenal biopsies, microbial cultures of gastric juice and duodenal mucosa, a xylose absorption test, and...

    Nonalcoholic fatty liver disease (NAFLD) is an increasing health problem worldwide, with genetic, epigenetic, and environmental components. Here, we describe the first example of NAFLD caused by genetic disruption of a mammalian potassium channel subunit. Mice with germline deletion of the KCNE2 potassium channel β subunit exhibited NAFLD as early as postnatal day 7. Using mouse genetics, histology, liver damage assays and transcriptomics we discovered that iron deficiency arising from KCNE2-dependent achlorhydria is a major factor in early-onset NAFLD in Kcne2(─/─) mice, while two other KCNE2-dependent defects did not initiate NAFLD. The findings uncover a novel genetic basis for NAFLD and an unexpected potential factor in human KCNE2-associated cardiovascular pathologies, including atherosclerosis. PMID:26984260

  7. Vitamin B12 in Health and Disease

    2010-03-01

    Full Text Available Vitamin B12 is essential for DNA synthesis and for cellular energy production. This review aims to outline the metabolism of vitamin B12, and to evaluate the causes and consequences of sub-clinical vitamin B12 deficiency. Vitamin B12 deficiency is common, mainly due to limited dietary intake of animal foods or malabsorption of the vitamin. Vegetarians are at risk of vitamin B12 deficiency as are other groups with low intakes of animal foods or those with restrictive dietary patterns. Malabsorption of vitamin B12 is most commonly seen in the elderly, secondary to gastric achlorhydria. The symptoms of sub-clinical deficiency are subtle and often not recognized. The long-term consequences of sub-clinical deficiency are not fully known but may include adverse effects on pregnancy outcomes, vascular, cognitive, bone and eye health.

  8. Stomach cancer screening in the adult health study population

    Examinations for parietal cell antibody (PCA) were performed on 1334 subjects of the Adult Health Study (AHS), Hiroshima, during a 1-year period. Findings revealed PCA in 112 subjects (8.4%), but no difference in frequency was noted by sex. The relationship of PCA to age showed the positive rate to be significantly higher in those age 50 or over than in those under 50. No correlation was noted between estimated A-bomb exposure dose and PCA frequency. PCA was found in 58 (11.6%) of the 502 cases presenting achlorhydria on tubeless gastric analysis, and particularly in the age 50 and over group, PCA was demonstrated in 43 (14.2%) of the 302 subjects presenting achlorhydria, which is a significant difference compared with the under 50 age group in which PCA was demonstrated in 15 (7.5%) of 200 such subjects. PCA was detected in 11 (7.2%) of 152 subjects with abnormal, or low, serum pepsinogen levels and in 20 (16.3%) of 123 subjects with high levels. The frequency of positive PCA was higher in patients diagnosed on upper gastrointestinal (GI) series as atrophic gastritis than in patients diagnosed as some other gastric disorder. PCA was negative in both of the two cases in whom a definite diagnosis of stomach cancer was established. However, in light of the finding of abnormal Diagnex Blue (DB) tests and positive PCA at a high frequency in the gastritis group and reports that gastritis provides the groundwork for stomach cancer, it is considered that care should be taken in cases with findings of abnormal DB test, abnormal serum pepsinogen levels, and positive PCA.

  9. [Neurological signs due to isolated vitamin B12 deficiency].

    Martinez Estrada, K M; Cadabal Rodriguez, T; Miguens Blanco, I; García Méndez, L

    2013-01-01

    Isolated vitamin B12 deficiency is a common condition in elderly patients but uncommon in patients younger than 30 years, with an average age of onset between 60 and 70 years. This is because the dietary cobalamin, which is normally split by enzymes in meat in the presence of hydrochloric acid and pepsin in the stomach, is not released in the stomachs of elderly patients, usually due to achlorhydria. Although the body may be unable to release cobalamin it does retain the ability to absorb vitamin B12 in its crystalline form, which is present in multivitamin preparations. Other causes are due to drugs that suppress gastric acid production. Neurological signs of vitamin B12 deficiency can occur in patients with a normal haematocrit and red cell indices. They include paresthesia, loss of sensation and strength in the limbs, and ataxia. Reflexes may be slowed down or increased. Romberg and Babinsky signs may be positive, and vibration and position sensitivity often decreases. Behavoural disorders range from irritability and memory loss to severe dementia. The symptoms often do not fully respond to treatment. A case is presented of an isolated vitamin B12 deficiency in 27 year-old female patient who was seen in primary health care. During anamnesis she mentioned low back pain, to which she attributed the loss of strength and tenderness in the right side of the body, as well as the slow and progressive onset of accompanied headache for the previous 4 days.

    2007-12-01

    Full Text Available Abstract Background Mucolipidosis Type IV is currently characterized as a lysosomal storage disorder with defects that include corneal clouding, achlorhydria and psychomotor retardation. MCOLN1, the gene responsible for this disease, encodes the protein mucolipin-1 that belongs to the "Transient Receptor Potential" family of proteins and has been shown to function as a non-selective cation channel whose activity is modulated by pH. Two cell biological defects that have been described in MLIV fibroblasts are a hyperacidification of lysosomes and a delay in the exit of lipids from lysosomes. Results We show that mucolipin-1 localizes to lysosomal compartments in RAW264.7 mouse macrophages that show subcompartmental accumulations of endocytosed molecules. Using stable RNAi clones, we show that mucolipin-1 is required for the exit of lipids from these compartments, for the transport of endocytosed molecules to terminal lysosomes, and for the transport of the Major Histocompatibility Complex II to the plasma membrane. Conclusion Mucolipin-1 functions in the efficient exit of molecules, destined for various cellular organelles, from lysosomal compartments.

  11. Reliability of the dual-isotope Schilling test for the diagnosis of pernicious anemia or malabsorption syndrome

    To evaluate the dual-isotope Schilling test for the diagnosis of pernicious anemia or malabsorption syndrome, 65 studies were selected for clinical correlation. Criteria for pernicious anemia included mean corpuscular volume greater than 100 cu micrometer, serum B12 greater than 100 ng/l, megaloblastic marrow, achlorhydria, reticulocytes greater than 5% on B12 therapy, atrophic gastritis, and elevated serum antibodies to parietal cells or intrinsic factor. Criteria for malabsorption syndrome included: decreased serum B12, folate, and carotene; increased fecal fat; abnormal D-xylose absorption; abnormal radiographic and biopsy findings. 58Co-cyanocobalamin and 57Co-cyanocobalamin bound to intrinsic factor were given orally to fasting patients; 1 mg of nonradioactive B12 was injected intramuscularly within two hours. Aliquots of 24-hour urine samples were counted. If the excretion of 58Co was less than 7% and the 57Co/58Co ratio was greater than 1.7, the test indicated pernicious anemia; a ratio less than 1.7 indicated malabsorption syndrome. Sensitivity, specificity, and accuracy of the dual-isotope Schilling test were 83%, 98%, and 94% for pernicious anemia, and 67%, 90%, and 86% for malabsorption syndrome, respectively

  12. Dual isotope Schilling test for measuring absorption of food-bound and free vitamin B12 simultaneously

    A prototype food-bound vitamin B12 (food-B12) absorption test has been developed in which 57Co-B12 was incorporated in vitro into egg yolk (yolk-B12) and served to volunteers in 50-g cooked portions together with toast and coffee for breakfast. Six hours later, 1 mg nonlabeled B12 was given intramuscularly and 24-hour urine was collected for radioactivity measurement. In separate tests, the absorption of yolk-B12 and crystalline 57Co-B12 was equally poor in patients with pernicious anemia. However, in patients with simple gastric achlorhydria and those who had undergone gastric surgery, the assimilation of yolk-B12 was impaired greatly, whereas the absorption of crystalline radio-B12 was normal. Egg yolk labeled with 58Co-B12 was administered together with crystalline 57Co-B12 in a dual isotope test with results similar to those obtained when the tests were prepared separately. This yolk-58Co-B12 test with its ability to detect malabsorption of food-B12 may be considered as an addition to the first part of the Schilling test

  13. Osteoporosis in Gastrointestinal Diseases.

    Krela-Kaźmierczak, Iwona; Szymczak, Aleksandra; Łykowska-Szuber, Liliana; Eder, Piotr; Linke, Krzysztof

    2016-01-01

    Secondary osteoporosis occurs as an isolated pathology or co-exists with types I and II osteoporosis. The gastroenterologist may come across osteoporosis or osteopenia in a patient with a gastrointestinal disease. This is often a young patient in whom investigations should be carried out and appropriate treatment initiated, aimed at preventing bone fractures and the formation of the best peak bone mass. Osteoporosis occurs in patients with the following conditions: Crohn's disease, ulcerative colitis, celiac disease, post gastrectomy patients, patients with short bowel syndrome, chronic hepatitis and cirrhosis, treated with steroids (steroid-induced osteoporosis) and patients using proton pump inhibitors chronically (state of achlorhydria). It is therefore necessary to approve a list of risk factors of secondary osteoporosis, the presence of which would be an indication for screening for osteoporosis, including a DXA study and the development of a separate algorithm for the therapeutic management of secondary osteoporosis accompanying gastrointestinal diseases, especially in premenopausal young women and young men, because there are currently no registered drugs with proven antifracture activity for this group of patients.

  14. Serum ferritin and stomach cancer risk among A-bomb survivors

    Using stored serum samples collected from 1970-72 and/or from 1977-79, serum ferritin, transferrin, and ceruloplasmin levels were immunologically determined for 233 stomach cancer and 84 lung cancer cases diagnosed from 1973-83 and for 385 matched controls from a fixed population of Hiroshima and Nagasaki atomic bomb survivors. Elevated stomach cancer risk was associated with low serum ferritin levels, with more than a threefold excess among those in the lowest quintile as compared to the highest ferritin quintile. The average serum ferritin concentration was 8% lower in the stomach cancer cases than in the controls. Risk did not vary with the time between blood collection and stomach cancer onset, remaining high among those with low ferritin levels five or more years before cancer diagnosis. Low ferritin combined with achlorhydria, diagnosed about 10 years before the blood collection and up to 25 years before cancer diagnosis, was an exceptionally strong marker of increased stomach cancer risk. No effect of transferrin or ceruloplasmin independent of ferritin was observed on gastric cancer risk. Lung cancer risk was not related to these three serum proteins. (author)

  15. Progress of gastric cancer etiology: N-nitrosamides in the 1990s

    Da Jun Deng

    2000-01-01

    Stomach carcinoma is still the leading cause of cancer death in China and the second one in the world. Its possible causes include: A) chemical factors such as intragastric formation of N-nitroso compounds (NOC) and high salt intake; B ) biological factors such as infection of Helicobacter pylori and biotoxins intake; and C ) nutritional factors such as deficiency of vitamin C, selenium, and other antioxidants. Nitrogenous precursors of NOC, e.g., alkylamines, alkylureas, alkylguanidines, and alkylamides, occur widely in nature and potential nitrosating agents, e.g., nitrite (NO2-) and NOx (the gaseous oxides of nitrogen ) are similarly widespread. Relationship between exposure to NOC and causes of human cancer was investigated extensively ten years ago. Results indicated that the exposures of NOC might contribute to the occurrences of malignancy in the upper digestive tracts including stomachs. It was also observed that both high salt intake and deficiency of some micronutrients enhanced NOC-induced carcinogenicity. Recent studies show that infection of H. pylori can lead to atrophic gastritis and achlorhydria, and promote endogenous formation of NOC indirectly[1] . Much attention has been paid to stomach cancer and NOC regarding the characterization of natural N-nitrosamides in human environment in the 1990s.

  16. Molecular physiology and genetics of Na+-independent SLC4 anion exchangers

    Alper, Seth L.

    2009-01-01

    Summary Plasmalemmal Cl–/HCO3– exchangers are encoded by the SLC4 and SLC26 gene superfamilies, and function to regulate intracellular pH, [Cl–] and cell volume. The Cl–/HCO3– exchangers of polarized epithelial cells also contribute to transepithelial secretion and reabsorption of acid–base equivalents and Cl–. This review focuses on Na+-independent electroneutral Cl–/HCO3– exchangers of the SLC4 family. Human SLC4A1/AE1 mutations cause the familial erythroid disorders of spherocytic anemia, stomatocytic anemia and ovalocytosis. A largely discrete set of AE1 mutations causes familial distal renal tubular acidosis. The Slc4a2/Ae2–/– mouse dies before weaning with achlorhydria and osteopetrosis. A hypomorphic Ae2–/– mouse survives to exhibit male infertility with defective spermatogenesis and a syndrome resembling primary biliary cirrhosis. A human SLC4A3/AE3 polymorphism is associated with seizure disorder, and the Ae3–/– mouse has increased seizure susceptibility. The transport mechanism of mammalian SLC4/AE polypeptides is that of electroneutral Cl–/anion exchange, but trout erythroid Ae1 also mediates Cl– conductance. Erythroid Ae1 may mediate the DIDS-sensitive Cl– conductance of mammalian erythrocytes, and, with a single missense mutation, can mediate electrogenic SO42–/Cl– exchange. AE1 trafficking in polarized cells is regulated by phosphorylation and by interaction with other proteins. AE2 exhibits isoform-specific patterns of acute inhibition by acidic intracellular pH and independently by acidic extracellular pH. In contrast, AE2 is activated by hypertonicity and, in a pH-independent manner, by ammonium and by hypertonicity. A growing body of structure–function and interaction data, together with emerging information about physiological function and structure, is advancing our understanding of SLC4 anion exchangers.

    2007-01-01

    Full Text Available Background/Aim. Autoimmune atrophic fundic gastritis induces the pernicious anemia (PA, as well as the changes in both epithelium and endocrine cells of gastric mucosa. The most important complications are: achlorhydria, hypergastrinemia, gastric cancer and enterochromaffin-like ( ECL carcinoid. The aim of this study was to examine ECL carcinoid histogenesis in A-gastritis associated with PA. Methods. During the period from 2000−2006, 65 patients with PA and 30 patients of the control group were examined. Histopathological examination was done in endoscopical biopsies of gastric mucosa fixed in 10% formaldehyde. Paraffin sections were stained with classic hematoxylin-eosin (HE; histochemical AB-PAS (pH 2.5, cytochemical argyrophilic Servier-Munger′s and immunocytochemical PAP methods for G cell identification and chromogranin A antibodies - specific marker for neuroendocrine ECL cells. Both G and ECL cells were counted per 20 fields, of surface 0.0245312 mm2 by a field. Basal gastrin serum levels were also examined by using radioimmunoassay (RIA method. The obtained results were statisticaly calculated by using Student΄s t test. Results. Marked antral G cell hyperplasia associated with corporal ECL hyperplasia was found. ECL cell hyperplasia was of simplex, linear, adenomatoid type to the pattern of intramucous ECL cell carcinoid. An average number of G cells was statistically significant in the patients with PA as compared to the control group (p < 0.05 as well as an average number of ECL cells. Conclusion. We concluded that antral G cell hyperplasia accompanied by gastrinemia induces ECL hyperplasia and ECL corporal carcinoid in A-gastritis and that their histogenesis develops trough simple, linear and adenomatoide hyperplasia. .

  18. Netazepide, a gastrin receptor antagonist, normalises tumour biomarkers and causes regression of type 1 gastric neuroendocrine tumours in a nonrandomised trial of patients with chronic atrophic gastritis.

    Andrew R Moore

    Full Text Available INTRODUCTION: Autoimmune chronic atrophic gastritis (CAG causes hypochlorhydria and hypergastrinaemia, which can lead to enterochromaffin-like (ECL cell hyperplasia and gastric neuroendocrine tumours (type 1 gastric NETs. Most behave indolently, but some larger tumours metastasise. Antrectomy, which removes the source of the hypergastrinaemia, usually causes tumour regression. Non-clinical and healthy-subject studies have shown that netazepide (YF476 is a potent, highly selective and orally-active gastrin/CCK-2 receptor antagonist. Also, it is effective in animal models of ECL-cell tumours induced by hypergastrinaemia. AIM: To assess the effect of netazepide on tumour biomarkers, number and size in patients with type I gastric NETs. METHODS: We studied 8 patients with multiple tumours and raised circulating gastrin and chromogranin A (CgA concentrations in an open trial of oral netazepide for 12 weeks, with follow-up 12 weeks later. At 0, 6, 12 and 24 weeks, we carried out gastroscopy, counted and measured tumours, and took biopsies to assess abundances of several ECL-cell constituents. At 0, 3, 6, 9, 12 and 24 weeks, we measured circulating gastrin and CgA and assessed safety and tolerability. RESULTS: Netazepide was safe and well tolerated. Abundances of CgA (p<0.05, histidine decarboxylase (p<0.05 and matrix metalloproteinase-7(p<0.10 were reduced at 6 and 12 weeks, but were raised again at follow-up. Likewise, plasma CgA was reduced at 3 weeks (p<0.01, remained so until 12 weeks, but was raised again at follow-up. Tumours were fewer and the size of the largest one was smaller (p<0.05 at 12 weeks, and remained so at follow-up. Serum gastrin was unaffected. CONCLUSION: The reduction in abundances, plasma CgA, and tumour number and size by netazepide show that type 1 NETs are gastrin-dependent tumours. Failure of netazepide to increase serum gastrin further is consistent with achlorhydria. Netazepide is a potential new treatment for type 1 NETs

  19. Effect of famotidine on the pharmacokinetics of apixaban, an oral direct factor Xa inhibitor

    Upreti VV

    2013-04-01

    underlying conditions (eg, achlorhydria, or by gastrointestinal pH-mediated effects of other histamine H2-receptor antagonists, antacids, or proton pump inhibitors. Given that famotidine is also an inhibitor of the human organic cation transporter (hOCT, these results indicate that apixaban pharmacokinetics are not influenced by hOCT uptake transporter inhibitors. Overall, these results support that apixaban can be administered without regard to coadministration of gastric acid modifiers. Keywords: apixaban, factor Xa inhibitor, famotidine, H2-receptor antagonists, hOCT inhibitor, drug–drug interaction

    bears a close relation to the severeness of the whole neurologic picture. 5. In cases of herniated nucleus pulposus the test of vibration sense can cooperate in the diagnosis of the side of the protrusion. However, it must be emphasized that the changes in pallesthesia have not, in such cases, the semiotic significance which some authors have assigned to them. 6. In the subacute combined degenerations of the spinal cord, with constitutional or acquired achlorhydria, the test of vibration sense is imperative, owing to the early and marked impairment of this form of sensation. The quantitative method can disclose, in several cases, the existence of pallesthesic changes not shown by routine procedures, particularly those involving the upper limbs. 7. In poliradiculoneuritis the vibration sense is deeply impaired, even in the upper limbs, where other forms of sensation can be normal by routine examination. 8. In trigeminal nerve lesions the quantitative test of vibration sense is of little semiotic significance, owing to the great variability of the thresholds in the head and to the frequent confusion between vibration and auditory senses. In the four cases tested the increase of the thresholds was slight, even in two cases with associated facial palsy. 9. In cases of parietal lobe injuries, including two cases of hemisphe-rectomy, the impairment of vibration sense is remarkable and coincident or not with changes in the joint sense. 10. In other diseases of the nervous system, the quantitative test of vibration sense has proved worthful for the diagnosis, either as a positive or sometimes as a negative finding.

    not maintain normal serum zinc ranges. Light microscopic studies of the intestinal villous architecture showed a normal pattern. However, ultrastructual examination of several epithelial cells revealed numerous intracellular vesicles. After zinc therapy, these changes were decreased. The lesions were postulated as the secondary result of zinc deficiency. 8. A 12-year-old girl presented with hypogammaglobulinemia, recurrent infections, chronic diarrhea and intestinal NLH. A barium meal and follow-through examination showed multiple nodules throughout the stomach and intestine. The nodules, all uniform in size, were 2 mm diameter. The barium enema did not show NLH in the colon. Mucosal biopsy of the stomach and jejunum revealed the typical histology of NLH in the lamina propria. Also, achlorhydria was present in this patient and her serum gastrin levels were very high; 315-775 pg/ml. 9. In 4 cases of intractable diarrhea in early infancy (by Avery G B), a jejunal biopsy showed shortening villi and nonspecific enterocolitis. Some patients were found with only low lactase or low lactase and sucrase levels. An electron microscope analysis of the small bowel in 2 cases showed alterations: increased pinocytosis in microvillus membranes and lysosomes by endocytosis of undigested macromolecular substances. I postulated that the stated evidence was causative of this clinical profile. 10. I frequently observed diarrhea as a clinical manifestation in glycogenosis type Ia and lipid malabsorption in one case. The light and electron photomicrographs showed intestinal absorption cells with the glycogen deposits in the inferior devision of nuclei. PMID:17228786
