Haematological Correlates of Helicobacter pylori Infection Amongst Children Receiving Care in a Private Setting in Port Harcourt, Rivers State

Helicobacter pylori is a spiral-shaped, gram-negative bacterium that basically colonizes the digestive tract of humans. It is an established cause of anaemia, leucopenia and thrombocytopenia and affects 70-95% of children in developing countries. We carried out a retrospective study of 140 children, presenting with abdominal discomfort and/or vomiting in a private hospital in Port Harcourt, South-South, Nigeria. Positive serology for H.pylori was established using IgG test kit and Full blood counts were done with an autoanalyzer. Sixty-four (45.7%) of the children studied were serologically positive for H.pylori infection, while 54.3%(76) were negative. H.pylori has been detected in virtually all age groups of children studied. Ten (15.6%) of the children with H.pylori positive serology had anaemia, 3.1%(2) had leucopenia and 12.5%(8) had leucocytosis. None of these was statistically significant. The overall seroprevalence of H.pylori in the children studied was high. Similarly, there was a high prevalence of haematologic derangements in the children with positive H.pylori assay compared to those children with negative serology for H.pylori. This was however not statistically significant. Routine screening of children with symptoms of abdominal discomfort for H.pylori and commencement of treatment for those with positive serology results is not recommended without a confirmatory test.
