Anemia is a significant health concern worldwide and can be the result of nutritional, environmental, social, and infectious etiologies. We estimated the prevalence of anemia in 336 pre-school children and 132 adults in the rural Central Plateau of Haiti and assessed associations with age, sex, household size, water source, sanitation, and Helicobacter pylori seroreactivity using logistic regression analysis; 80.1% (269/336) of children and 63.6% (84/132) of adults were anemic. Among children, younger age was associated with increased prevalence of anemia (adjusted odds ratio [aOR] = 4.1, 95% confidence interval [CI] = 1.5-11.1 for children 6-11 months compared with children 48-59 months). Among adults, 50.8% were H. pylori-seropositive, and seropositivity was inversely associated with anemia (aOR = 0.4, 95% CI = 0.2-0.9). Anemia prevalence in this region of Haiti is very high and not attributable to sanitary conditions or a high prevalence of H. pylori infection.

    • "Presumably, chronic H.p infection is very likely to cause anemia, given its nature of chronic infection in adults and predisposition to gastrointestinal mucosal lesions, both of which have been attributed as the common causes of anemia [12]. Our data have agreed with previous reports on no significant association between chronic H.p infection and anemia [13–16]. Some studies have reported decreased iron store in positive H.p infection populations [17–20]. "

    ABSTRACT: Background. Chronic Helicobacter pylori infection and iron-deficiency anemia (IDA) are common in adults. Although the most common causes of IDA usually arise from the gastrointestinal tract, the association between chronic Helicobacter pylori infection and anemia remains unclear. Aim. To evaluate the association of chronic Helicobacter pylori infection and IDA. Materials and Methods. We enrolled 882 patients from January 2010 to April 2013. The status of Helicobacter pylori (H.p) infection was confirmed and blood samples from the same participants were taken on the same day to check the level of hemoglobin, serum iron, ferritin, and total iron-binding capacity (TIBC). Results. No significant difference was noted from the demographic data. The average level of hemoglobin (Hb) was not different between negative and positive groups, pos 13.57 g/dL versus neg 13.65 g/dL (P = 0.699). Although the levels of serum IDA related parameters were expected in positive group (lower serum iron and ferritin and higher TIBC) these differences did not reach statistical significance (P = 0.824 for iron, P = 0.360 for ferritin, and P = 0.252 for TIBC). Conclusion. Chronic Helicobacter pylori infection is not attributed to IDA. The levels of hemoglobin, serum iron and ferritin, and TIBC remain unaffected after chronic H.p infection. Large-scale clinical studies are needed to prove the association.

    ABSTRACT: In the previous year, some extragastric diseases, possibly linked to Helicobacter pylori infection, have been largely investigated. There are, in fact, several studies concerning cardiovascular diseases, lung diseases, hematologic diseases, eye and skin diseases, hepatobiliary diseases, diabetes mellitus, and neurological disorders. Among them, the relationship between bacterial CagA positivity and coronary heart disease is reportedly emphasized. Concerning normal tension glaucoma, new interesting data are playing in favor of the association with H. pylori infection. For other diseases, there are many interesting results, although more studies are needed to clarify the reality of the proposed association.

    ABSTRACT: Helicobacter pylori is a common gut pathogen that is linked to many complications of pregnancy such as iron deficiency anemia, pre-eclampsia and thrombocytopenia. There are no published data on H. pylori in Sudan. A cross-sectional study was conducted during the period May-June 2012 at the antenatal care unit of Khartoum Hospital, Sudan, to investigate prevalence of H. pylori and its association - if any - with anemia and thrombocytopenia. Obstetric and medical histories were gathered using questionnaires. Hemoglobin and serum ferritin were measured and H. pylori antibodies (IgA and IgG) investigated using ELISA. Among 179 women, rates of positivity for specific IgG formed against H. pylori were 69.8% (125/179), 94.0% (168/179) and 5.6% (10/179) for IgA, IgG and both IgG and IgA, respectively. There was no association between the expected risk factors (age, parity, education) and H. pylori seropositivity. Of these women, 42/179 (24.3%), 50/179 (28.9%) and 19/179 (11%), respectively, were anemic (hemoglobin <11 g/dl) or had iron deficiency (serum ferritin <15 µg/l) or iron deficiency anemia. There was no association between H. pylori infection and anemia (OR=1.0, 95% CI=0.3-3.2, p=1.0), iron deficiency (OR=0.6, 95% CI=0.1-3.8, p=0.367) or thrombocytopenia (OR=2.0, 95% CI=0.4-8.4, p=0.322). There is a high prevalence of H. pylori infection among pregnant women in Khartoum, Sudan, and it is not associated with anemia or thrombocytopenia.
