Computer records of patients endoscoped over a 34-month period were studied to assess the diagnostic yield of gastrointestinal endoscopy in patients with anaemia. Patients with obvious gastrointestinal bleeding and known gastrointestinal pathology were excluded. On hundred and thirty-six patients were endoscoped for anaemia. Eighty-three of them (61%) had iron deficiency anaemia and 53 (39%) had other types of anaemia. The ages of the patients with iron deficiency anaemia (mean 56 years) were significantly lower than those of other anaemias (means 65 years), (p less than 0.003). Patient characteristics were otherwise comparable. There were significant endoscopic findings (ulcers, carcinoma and haemorrhagic or erosive gastritis) in 26 of 83 patients (31%) with iron deficiency anaemia, in 11 of 53 patients with other anaemias (21%) and 37 of 136 patients (27%) combined. Significant endoscopic findings were found in 506 of 2224 patients (23%) endoscoped during this period who were not anaemic, did not have obvious gastrointestinal haemorrhage and were not known to have gastrointestinal diseases. The diagnostic yield for iron deficiency anaemia was significantly higher than for the non anaemic group (p less than 0.05). There was no difference between the diagnostic yields of iron deficiency and other anaemias, other anaemias and the non anaemic group, or total anaemias and the non anaemic group. Gastrointestinal symptoms and history of analgesic or steroid usage did not appear to increase the incidence of gastrointestinal lesions in either iron deficiency anaemia or other anaemias. Twenty-three of 41 patients (56%) who had no cause for anaemia found at the end of all investigations were colonscoped.(ABSTRACT TRUNCATED AT 250 WORDS)

Watermelon stomach, or gastric antral vascular ectasia, is an uncommon cause of gastrointestinal blood loss, which can easily be overlooked and which is eminently curable. A 76 year old woman who was repeatedly misdiagnosed as having incidental antral gastritis with occult iron deficiency is described.

Livex is a lyophilised preparation of the bovine blood which contains 70% of proteins and 0.3% of iron. Livex was given to 25 patients with iron deficiency anemia (group I), and 25 patients with lymphoreticular malignancies accompanied by iron deficiency with or without anemia. The dose was 5 g t.i.d. for 3 months. The majority of patients of group I were women. Excessive menstrual bleeding and chronic gastritis were most common causes of iron deficiency in this group. Livex statistically significantly increased hemoglobin, hematocrit, corrected reticulocyte count, mean erythrocyte hemoglobin, serum iron, percent transferrin saturation, and leukocyte count. Therapy produced significant increase in serum iron, total iron binding capacity, and percent transferrin saturation in patients with lymphoreticular malignancies.

To assess the indications and yield of single session panendoscopy (SSPE), patients who underwent colonoscopy and esophagogastroduodenoscopy (EGD) at the same time were retrospectively reviewed. Endoscopy records and patient charts of 101 patients who underwent SSPE during a 45-month period were analyzed for demography, indication, and results. Average age was 72.9 years. Common indications were positive occult blood tests (74%), anemia (28%), altered bowel habits (15%), and iron deficiency (13%). Most frequent findings at colonoscopy included diverticulosis (47%), polyps (37%), hemorrhoids (28%), and arteriovenous (AV) malformations (13%). Nine cases of cancer were found, seven of which were right-sided. Colonoscopy was normal in 12 per cent. EGD findings include esophagitis (55%), hiatal hernia (47%), and gastritis (33%). Eleven per cent were normal. Occult blood loss is not predictive of either a positive or negative study. SSPE is a safe and specific approach; however, based on this study, colonoscopy is recommended as the initial study for occult blood loss with plans to proceed to EGD when the lower endoscopy is normal. Even when the colonoscopy suggests the etiology for occult blood loss, EGD will yield a significant number of treatable and unsuspected lesions.

Plummer-Vinson syndrome (PVS) is characterized by iron deficiency anemia, upper esophageal stricture, cervical dysphagia, and glossitis. The precise role of iron deficiency in PVS has yet to be defined and remains a subject of much debate. A 29-year-old woman with PVS is presented. The patient had a 4-year history of severe iron deficiency anemia, a 2-year history of progressive dysphagia and weight loss, and a greater than 90% benign upper esophageal stricture. Iron therapy alone resolved her dysphagia and anemia, and a follow-up esophagram 1 year later showed a residual stenosis of less than 30%. The development of severe iron deficiency anemia in this patient 2 years before the onset of dysphagia, as well as the response of the stricture to iron repletion, supports the theory that iron deficiency can cause dysphagia and upper esophageal strictures. The occurrence of glossitis, gastritis, and esophagitis in iron deficiency demonstrates the adverse effects of iron depletion on the rapidly proliferating cells of the upper alimentary tract.

Serum ferritin concentrations and bone marrow stainable iron were determined in 122 adult out-patients (seventy males) with gastritis, gastric ulcer and duodenal ulcer. Half of the forty-four patients with iron deficiency (serum ferritin level below 20 micrograms/l) received peroral iron therapy (200 mg Fe++ daily). In most of the treated patients serum ferritin levels increased and the amount of bone marrow stainable iron in half of them also increased. Measurement of body iron stores by serum ferritin determinations and restoration of low body iron stores in these patients is of practical importance.

Chronic gastritis is a histological diagnosis, relying on separate biopsies from antral and fundic mucosa. According to Strickland type A gastritis corresponding to pernicious anemia should be differentiated from type B gastritis, maybe induced by duodeno-gastric reflux. Intensity of inflammatory infiltration and atrophy of the specific glands correlate by and large with acid secretion, however, not with alcohol or nicotine abuse or iron deficiency. Chronic atrophic gastritis may lead to gastric carcinoma of the intestinal type, in gastric ulcer patients localization of the ulcer crater is determined by the spread of gastritis. The histological diagnosis of chronic gastritis has no therapeutic consequences; however, in type A gastritis regular endoscopic follow-up studies in 2-5 year intervals seem advisable.

Through the efforts of Correa, Cuello, Haenszel, Tannenbaum and others it was learned that the incidence of gastric cancer in certain areas of Narino (Colombia) was among the highest in the world. These areas of high risk for gastric cancer were adjacent to an area of substantially lower risk. Gastric biopsies from healthy volunteers residing in the "high risk" area exhibited a greater incidence of superficial gastritis and chronic atrophic gastritis with and without intestinal metaplasia than those from the low risk area. The latter pathological finding is considered to be a precursor lesion to gastric cancer. Volunteers from the "low risk" area as well as individuals from Cali in the coastal region and Cartegena on the coast, also exhibited a similar spectrum of pathology but at a substantially reduced frequency. Natives of both cities were also at lower risk for gastric cancer than inhabitants of Narino. It was found that the water supply of the "high risk" area contained a higher concentration of nitrate than water in the "low risk" area. Correa et al. hypothesized that the high nitrate concentrations of well water contributed to the formation of N-nitroso compounds in the stomachs of these individuals early in life. The occurrence of this putative carcinogen in combination with the abrasive action of dietary grains contributed to a series of mutations in the gastric epithelium progressing through a sequence of pathologic changes, loss of gastric acid and culminating in gastric cancer. In the current report individuals in a Medellin population who were admitted with abdominal complaints and were found to be iron deficient exhibited the same spectrum of gastric pathology described by previous investigators. Superficial gastritis, chronic atrophic gastritis and achlorhydria have also been described in association with chronic iron deficiency (and/or associated nutritional defects) per se. The development of these lesions are likely to occur within the first two decades of life when iron requirements are maximal. It is suggested that these changes preceed the development of gastric cancer. Bacterial colonization of the achlorhydric stomach may facilitate nitrate reduction and the formation of a putative carcinogen N-nitroso compound(s) from nitrate in the water supply. Additionally, the effects of chronic iron deficiency on host immune defense may compromise these mechanisms and permit tumor growth with minimal immune intervention.

The history of a 45-year-old male type 1 diabetic patient is presented. At the age of 29 years, he was diagnosed to have an autoimmune hepatitis with incipient liver cirrhosis. Five years later, a successful liver/pancreas transplantation was performed. Eighteen months later, however, pancreatic insufficiency occurred due to thrombosis of the pancreatic graft. Besides these conditions, iron deficiency, pernicious anemia, and autoimmune gastritis were also diagnosed. Serum parietal cell antibodies (PCA) and intrinsic factor antibodies (AIF) were positive. At 45, this patient was found to have a gastric carcinoid tumor. The clinical importance of PCA is discussed with regard to chronic atrophic gastritis and pernicious anemia, which both predispose toward gastric carcinoid tumors. Autoimmune type 1 diabetic patients who have a high prevalence of PCA should be screened for gastric autoimmune manifestations and tumors, as the history of this patient illustrates.

Iron deficiency anemia is a common public health problem in the Alaska Native population. Yet, a clear etiology has eluded researchers for decades. Previous studies suggested a link between Helicobacter pylori infection, gastrointestinal blood loss due to hemorrhagic gastritis, and generalized iron deficiency anemia in adult Alaska Natives. Therefore, we examined the association between the prevalence of H. pylori-specific immunoglobulin G (IgG) and serum ferritin levels, a marker of iron deficiency. A random sample of 2,080 serum samples from Alaska Native residents drawn between 1980 and 1986 from residents in 13 regions was selected, and the samples were stratified by age, sex, and region. Overall, 75% were positive for H. pylori-specific IgG. The rate of H. pylori seropositivity increased with age; by age 14 years, 78% of the residents were positive. There were no gender differences in H. pylori seropositivity. However, marked regional differences were observed. Serum ferritin levels of <12 ng/ml were found most commonly among persons <20 years of age and among women of childbearing age. A significant association between low serum ferritin levels and prevalence of H. pylori-specific IgG was found, particularly for people aged less than 20 years. H. pylori may be a factor contributing to the iron deficiency anemia in the Alaska Native population.
