Secondary Cervical Cancer Prevention of Vulnerable Women With HPV and HIV Co-infection in India

研究简介（原文）

Cervical cancer (CC) remains one of the most common malignancies among women in India, with nearly 100,000 women diagnosed annually and over 60,000 preventable deaths annually. With high-risk human papillomavirus (HR-HPV) as the causative agent for CC, one risk factor that places women at high risk for CC is human immunodeficiency virus (HIV), as impaired immune response against Human papillomavirus (HPV) may result in persistent HR-HPV infection, a critical risk factor for progression of HPV-related cervical oncogenesis. Progression of precancerous lesions among women living with HIV (WLH) is also associated with: 1) lack of HPV screening; 2) high levels of depressive symptoms and stigma; and 3) malnutrition, which negatively impacts the activation and proliferation of immune cells. Yet programs that offer WLH with comprehensive services focused on HPV screening and psychological and nutritional support are almost non-existent, and the gap is critical. Nutrition plays an integral role in relationship to HPV/HIV co-infection, as demonstrated by an increased risk of HR-HPV associated with poor nutrition; nutritional deficiencies are likewise linked to cervical intra-epithelial neoplasia. The immunological effect of malnutrition may also be exacerbated among WLH due to elevated energy demands of chronic immune activation; worsened with HPV/HIV co-infection. Further, depressive symptoms (aka depression for brevity) partially mediate the effect of food insecurity on HIV viral suppression. In our completed ASHA-Nutrition R01 study of antiretroviral (ART) adherence, the investigators trained lay community health peer counselors, named Accredited Social Health Activist (ASHA), to improve the health of 600 rural WLH by providing emotional support, skill-building, nutrition education, and/or protein-enriched food supplements. In that study, our intervention, co-delivered by our trained peer counselors, and guided by nurses, led to increased CD4+ T cell recovery and improved anthropometric and psychosocial outcomes. The investigators found that peer counselors support plus protein supplements and nutritional education were significantly associated with improved CD4 counts and increased lean mass at 18 months (P \< 0.001), as well as significant improvements in depression, ART adherence, social support and internalized stigma. In our sub study, CC screening of 598 of these WLH revealed that 13% were found to have abnormal cervical lesions and 4 (1%) had squamous CC. Preliminary evidence also revealed that nutritional supplements may be associated with a 40% reduction in the risk of abnormal cervical lesions (adjusted odds ratio \[aOR\] = 0.60), with an association between serum albumin and reduced risk of abnormal lesions (aOR= 0.39). With a focus on secondary prevention of CC, the investigators hope to mitigate the link between HR-HPV persistence and risk of CC as well as improve the health of women co-infected with HPV/HIV (W-Co-V). Our stellar team plans to build upon our prior ASHA-Nutrition intervention, using formative research to refine a nurse-led, peer counselors co-delivered, nutrition-enhanced SAKHI HPV intervention, adapted for W-Co-V. This will be followed by a randomized controlled trial (RCT), assessing the efficacy of our refined comprehensive, multifaceted SAKHI HPV intervention, as compared with an enhanced Standard of Care (SOC+) (usual care + 3 sessions \[wellness, basic nutrition and HPV/HIV health promotion\]) among 348 high-risk co-infected women to prevent CC while remaining engaged in the HIV treatment cascade, and managing nutritional health. Recruited participants will be individually randomized in a 1:1 ratio to one of the two study arms. Our Primary outcome is HR-HPV persistence (2 positive tests for the same HR-HPV type, separated by 12-18 months). The two aims incorporating RCT interventions are as follows: Aim 2. To evaluate the efficacy of SAKHI HPV intervention among 348 W-Co-V on the primary outcome (HR-HPV persistence) as compared to the Enhanced Standard of Care (SOC+) program. H2: Compared to the SOC+ participants, SAKHI participants will have lower rates of HR-HPV persistence. Aim 3. Assess the impact of the SAKHI program secondarily on: 1) HIV indices (HIV viral load; CD4 count); 2) Nutritional index (serum albumin) at 6-, 12-, and 18-months.
