ABSTRACT People infected with human immunodeficiency virus (HIV) have an increased risk of some malignancies, but little is known about the effects of infection on risk of cancers of the upper gastrointestinal tract. We evaluated the risks of different histologic and anatomic subtypes of carcinomas and non-Hodgkin lymphomas (NHLs) of the stomach and esophagus in people with acquired immunodeficiency syndrome (AIDS).
We analyzed data from the HIV/AIDS Cancer Match Study, which links data collected from 1980 to 2007 for 16 US population-based HIV and AIDS and cancer registries. We compared risks of stomach and esophageal malignancies in people with AIDS (N = 596,955) with those of the general population using standardized incidence ratios (SIRs). We assessed calendar trends using Poisson regression.
People with AIDS had increased risks of carcinomas of the esophagus (SIR, 1.69; 95% confidence interval [CI], 1.37-2.07; n = 95) and stomach (SIR, 1.44; 95% CI, 1.17-1.76; n = 96). Risk was increased for esophageal adenocarcinoma (SIR, 1.91; 95% CI, 1.31-2.70) and squamous cell carcinoma (SIR, 1.47; 95% CI, 1.10-1.92). People with AIDS had greater risks of carcinomas of the gastric cardia (SIR, 1.36; 95% CI, 0.83-2.11) and noncardia (SIR, 1.53; 95% CI, 1.12-2.05) than the general population. Although most stomach and esophageal NHLs that developed in people with AIDS were diffuse large B-cell lymphomas, these individuals also had an increased risk of stomach mucosa-associated lymphoid tissue lymphoma (SIR, 5.99; 95% CI, 3.19-10.2; n = 13). The incidence of carcinomas remained fairly constant over time, but rates of NHL decreased from 1980 to 2007 (P(trend) < .0001).
People with AIDS are at increased risk for developing esophageal and stomach carcinomas and NHLs. Although the incidence of NHL decreased from 1980 to 2007 as treatments for HIV infection improved, HIV-infected individuals face continued risks of esophageal and stomach carcinomas.

    ABSTRACT: A multifactorial and multistep model of gastric cancer (GC) is currently accepted, according to which different environmental and genetic factors are involved at different stages in the cancer process. The aim of this article is to review the most relevant information published on the relative contribution of genetic and environmental factors. Large meta-analyses confirmed the association between IL8, IL10, TNF-b, TP53 and PSCA, while genetic variation at different genes such as XPG, PLCE1, HFE, ERCC5, EZH2, DOC2, CYP19A1, ALDH2, and CDH1 have been reported to be associated with GC risk. Several microRNAs have also been associated with GC and their prognosis. Cohort studies have shown the association between GC and fruit, flavonoid, total antioxidant capacity, and green tea intake. Obesity was associated with cardia GC, heme iron intake from meat with GC risk. Several large meta-analyses have confirmed the positive association of GC with salt intake and pickled foods and the negative association with aspirin use.

    ABSTRACT: Human herpes viruses (HHVs) have been frequently detected in the gastrointestinal (GI) tract and may contribute to the development of gastric cancer. In the present study, the detection rate and viral load of Epstein Barr virus (EBV), HHV-6 and Cytomegalovirus (CMV) were assessed in the GI tract of human immunodeficiency virus (HIV) positive patients and of uninfected patients. The analysis revealed a significantly higher detection rate of EBV and HHV-6 in HIV-infected individuals than in uninfected subjects (88.5 vs 63 %; p = 0.03). Moreover, EBV DNA load was significantly higher in the stomach of HIV patients than in controls. These data suggest that the HIV infection status may increase the persistence of these viruses in the GI compartment. Intriguingly, CMV DNA was undetectable in all biopsy specimens analyzed.

    ABSTRACT: : The purpose of this review was to outline the interaction between HIV and noncommunicable diseases affecting the gastrointestinal (GI) tract, liver, and nutritional disorders in low- and middle-income countries (LMICs), and to identify research priorities. Noncommunicable GI tract disorders are only moderately influenced by HIV, and peptic ulceration is actually less common. However, the impact of HIV on GI cancers needs further investigation. HIV interacts strongly with environmental enteropathy, exacerbating malabsorption of nutrients and drugs. HIV has 2 major effects on noncommunicable liver disease: drug-induced liver injury and nonalcoholic fatty liver disease (particularly in persons of African genetic descent). The effect of HIV on nutrition was one of the first markers of the epidemic in the 1980s, and HIV continues to have major nutritional consequences. Childhood malnutrition and HIV frequently coexist in some regions, for example, southern Africa, resulting in powerful negative interactions with poorer responses to standard nutritional rehabilitation. HIV and nutritional care need to be better integrated, but many questions on how best to do this remain unanswered. Across the spectrum of GI, hepatic, and nutritional disorders in HIV infection, there is increasing evidence that the microbiome may play an important role in disease pathogenesis, but work in this area, especially in low- and middle-income countries, is in its infancy.
