“…Several researchers have examined epidemiologic factors associated with H. pylori infection using varied study designs (e.g., prospective cohorts, cross-sectional, case-control) and reported conflicting results (Table 1). [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] These varied results might be explained by various factors including small sample sizes, differing patient populations, and inconsistent testing and detection methods.…”

“…Quiros et al 18 compared H. pylori seroepidemiology in a total of 570 patients who were classified as at-risk to a control group of 110 adults and 60 children. The at-risk groups consisted of 93 mentally handicapped children, 40 heterosexual couples, 101 HIV-infected patients, 86 patients with chronic renal failure, and 40 individuals with gastrointestinal complaints.…”

Gastrointestinal (GI) discomfort is a common complaint among patients infected with HIV. GI symptoms can be caused by a myriad of factors including but not limited to coinfections, antiretroviral therapy, medications for opportunistic infections, and nutritional status. Some researchers have hypothesized that Helicobacter pylori infection may be more common among HIV-infected patients as a result of immune suppression. An increased incidence of H. pylori infection would contribute to the prevalence of GI complaints in this population. Several epidemiologic studies have examined the relationship between H. pylori infection and HIV. While studies have generally reported conflicting results that may be related to the use of varied study designs, some identifiable patterns can be discerned. It does appear that the incidence of H. pylori infection is lower among patients with AIDS compared to matched HIV-infected and -uninfected controls. This review discusses the various epidemiologic trials that have been conducted in this area and describes the potential physiologic mechanisms to explain these findings. The clinical applicability of these studies as well as limitations are also discussed. A greater number of well-designed and controlled trials are needed before any definitive conclusions regarding these diseases can be made, until such time clinicians should be aware of the potential issues regarding H. pylori screening and management in the context of HIV. Research in this area might also provide information relating to HIV-associated GI changes and the role of these changes in HIV pathogenesis.

“…pylori is known for its intrafamilial clustering [21][22][23][24] and is associated with crowded conditions [25,26]. Its high prevalence among institutionalized mentally challenged individuals implies the possibility of its person-to-person transmission [22,27]. In Egypt, concomitant infection with G. lamblia and H. pylori was reported in a number of studies [28][29][30].…”

Introduction: Concomitant infections with pathogens are common, particularly when there are shared modes of infection or when one pathogen promotes the other. Residence among closed-type care institutions may pose an additional risk of such infections. Mentally challenged patients in rehabilitation centers constitute one of the special needs groups exposed to parasitic infections, including giardiasis. Several studies reported concomitant infection with G. lamblia and H. pylori worldwide and in Egypt; however, the co-existence of these two pathogens among mentally challenged individuals remains unexplored. The present study aimed to study the prevalence and association between G. lamblia and H. pylori among mentally challenged patients in rehabilitation centers in Alexandria, Egypt. Methodology: 200 individuals admitted to four mental rehabilitation centers in the period from June 2013 to January 2014, who guardians gave informed consent, were recruited. Stool samples were collected and subjected to trichrome stain for G. lamblia and to antigen detection for H. pylori. Results: The overall prevalence rates of G. lamblia and H. pylori were 8.5% and 24.0%, respectively. Monoinfection rates were 5.5% for G. lamblia and 21.0% for H. pylori, while concomitant infection with both species was detected in only 3.0% of cases. However, individuals who were H. pylori-positive were about two times more likely to be infected with G. lamblia than those who were H. pylori-negative (12.5% vs. 7.2%). Conclusions: Mentally challenged individuals in Alexandria harbouring H. pylori are about two times more likely to be exposed to G. lamblia. Large-scale studies are recommended to confirm this association.

“…Physically and mentally disabled children are particularly vulnerable to microorganisms because of their different feeding abilities, toilet needs, and sanitary arrangements. A high frequency of H. pylori infection has been shown among children with mental retardation (14)(15)(16)(17)(18)(19); however, there are no data regarding H. pylori infection in other metabolic diseases with mental retardation in the literature. Therefore, we evaluated the frequency of H. pylori infections among children with PKU.…”

<i>Helicobacter pylori</i> Infection among Children with Phenylketonuria

SUMMARY: This study aimed to determine the frequency of Helicobacter pylori infections in children with phenylketonuria (PKU). Sixty-six children with PKU (35 boys, 31 girls; mean age, 8.2 ± 6.7 years) and 32 outpatient controls (15 boys, 17 girls; mean age, 9.6 ± 4.7 years) were studied. Socioeconomic factors did not differ between the two groups. The frequency of H. pylori infections was higher in patients with PKU (28.1z) than in healthy controls (9.4z). In particular, a higher frequency of infection was detected in patients with PKU with poor metabolic control (51.8z). The frequency of H. pylori infection in patients with PKU with good metabolic control was only 10.2z. There was no difference in the mean total WISC-R score between the poor and good metabolic control groups. A high frequency of H. pylori infection in children with PKU with poor metabolic control could be related to many factors. Advanced and standardized clinical studies on H. pylori infections in children with PKU are required.
