Abstract

Introduction: Aflatoxins are environmental hazards; potent carcinogenic and immunosuppressive agents that contaminates corn and other crops. A high proportion of hepatocellular carcinoma cases are caused by exposure to dietary aflatoxins. Cervical cancer is common among Ugandan women; this malignancy is caused by persistent infection with oncogenic HPV types. An analysis was performed to examine associations between plasma aflatoxin B₁ (AFB₁) detection and oncogenic HPV detection (HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) and persistence among Ugandan women.

Methods: Ugandan women were enrolled in a prospective cohort study. Annual cervical swabs (Enrollment, Month 12 and Month 24) were tested for oncogenic HPV. Plasma AFB₁ concentration was measured (as AFB₁-lysine conjugate, or AFB₁-lys) at Enrollment and Month 12. Multivariable regression models were fitted to examine associations of plasma AFB₁-lys concentrations and oncogenic HPV controlling for demographic and behavioral characteristics.

Results: The analytical sample consisted of 114 women with a mean age of 33.2 years; 60 women were living with HIV; 59 were receiving antiretroviral therapy (ART) at enrollment. AFB₁-lysine adducts (AFB₁-lys) was detected in plasma from all 114 women. Multivariable regression models showed that plasma AFB₁-lys concentration was associated with a higher risk of detection of HPV 16 (OR = 2.64, 95% CI = 1.42-4.90, p = 0.002) and HPV 18 (OR = 2.24, 95% CI = 1.27-3.96, p = 0.005), and persistence of HPV 16 (OR = 3.16, 95% CI = 1.59-6.26, p = 0.001) and HPV 18 (OR = 2.06, 95% CI = 1.09-3.90, p = 0.025), controlling for age, marital status, years of education, home ownership, distance to health care, number of lifetime sex partners, age of first sex, and HIV status.

Conclusions: AFB₁ is an environmental hazard that is prevalent among Ugandan women. Higher plasma AFB₁-lys concentration was associated with detection and persistence of HPV 16 and HPV 18; this association was independent of HIV status. As a result, these women may be at increased risk of cervical cancer. Further studies are needed to determine the mechanisms involved.

在乌干达妇女中，较高的血浆AFB1浓度与HPV 16和HPV 18检测和持续风险增加有关。

简介：黄曲霉毒素是环境危害；污染玉米和其他作物的强致癌物和免疫抑制剂。高比例的肝细胞癌病例是由暴露于饮食黄曲霉毒素引起的。宫颈癌在乌干达妇女中很常见；这种恶性肿瘤是由致癌型HPV持续感染引起的。分析了血浆黄曲霉毒素B1 （AFB1）检测与致癌HPV检测（HPV型16、18、31、33、35、39、45、51、52、56、58、59、66和68）和乌干达妇女持续性之间的关系。方法：乌干达妇女被纳入前瞻性队列研究。每年宫颈拭子（入组12个月和24个月）检测致瘤性HPV。在入组和第12个月测定血浆AFB1浓度（AFB1-赖氨酸偶联物，或AFB1-赖氨酸）。采用多变量回归模型检验血浆afb1 - lyys浓度与控制人口统计学和行为特征的致癌HPV之间的关系。结果：分析样本包括114名女性，平均年龄33.2岁；60名妇女感染艾滋病毒；59人在入组时接受抗逆转录病毒治疗（ART）。114名妇女血浆中均检测到afb1 -赖氨酸加合物（AFB1-lys）。多变量回归模型表明,等离子体AFB1-lys浓度与检测HPV 16的风险更高(OR = 2.64, 95% CI -4.90 = 1.42, p = 0.002)和人乳头状瘤病毒18 (OR = 2.24, 95% CI -3.96 = 1.27, p = 0.005),和持久性的HPV 16 (OR = 3.16, 95% CI -6.26 = 1.59, p = 0.001)和人乳头状瘤病毒18 (OR = 2.06, 95% CI -3.90 = 1.09, p = 0.025),控制了年龄,婚姻状况,多年的教育,拥有住房,距离医疗、终生性伴侣,第一次性行为的年龄和艾滋病毒状况。结论：AFB1是一种在乌干达妇女中普遍存在的环境危害。较高的血浆afb1 - lyys浓度与HPV 16和HPV 18的检测和持续有关；这种联系与艾滋病毒状况无关。因此，这些妇女患子宫颈癌的风险可能会增加。需要进一步的研究来确定所涉及的机制。
