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

ABSTRACT In India, cervical cancer (CC) remains one of the most common malignancies among women, with about 100,000 women diagnosed annually. HIV promotes the progression of precancerous lesions. Among women living with HIV/AIDS, a lack of Human Papilloma Virus (HPV) screening, coupled with high levels of depressive symptoms and stigma, along with malnutrition, negatively impact the activation and proliferation of immune cells, further promoting development of precancerous lesions in the cervix. Programs for women living with HIV (WLH) that include HPV screening and psychosocial and nutritional support are almost non-existent, and the gap is critical in hopes of reducing high CC incidence rates. In our recently completed R01 study of 600 WLH in rural India, we assessed the impact of our “ASHA-Nutrition” intervention, co-delivered by our community health workers (ASHA), and led by nurses, in providing emotional support, skill-building, nutrition education, and/or protein-enriched food supplements. Our findings revealed that the nurse-led ASHA support plus protein supplements and nutritional education showed a significant association with improved CD4+ T cell counts and increased lean mass at 18 months as well as improved depression, social support and stigma. CC screening of 598 of these WLH revealed 13% had abnormal cervical lesions and 4 (1%) had squamous CC. Further, our preliminary data suggest that nutritional supplements may be associated with a 40% reduction in the risk of abnormal cervical lesions. Our stellar team plans to build upon our prior successful model to refine our newly developed nurse-led, ASHA co-delivered, nutrition-enhanced, ASHA-Health HPV intervention, adapted to the needs of a high-risk sub-population of women co-infected with HPV and HIV (W-Co-V), and randomized by village clusters among women treated in antiretroviral treatment (ART) centers in underserved Karnataka, India. With a major focus on secondary prevention of CC, we hope to mitigate the link between high-risk human papillomavirus (HR-HPV) persistence (measured as 2 positive tests for the same HR-HPV type, separated by 12 -18 months), risk of CC, as well as improved health of W-Co-V. We will conduct a parallel-group cluster randomized clinical trial, assessing the efficacy of our refined comprehensive, ASHA-Health HPV intervention, as it relates to CC prevention, ongoing engagement in the HIV treatment cascade, and managing nutritional health among 420 high-risk co-infected women, as compared with an enhanced Standard of Care (SOC+). Our Primary outcome is HR-HPV persistence. Secondary outcomes will be the improvement in: 1) HIV indices (HIV viral load and CD4+ T cells); 2) Nutritional indices (serum albumin levels, Vitamin A, Vitamin D, and Iron); 3) Mental health (depression and HPV/HIV internalized stigma); and 4) Engagement in care (HPV/HIV appointment keeping and ART adherence); all measures will be assessed at baseline, and at 6-, 12-, and 18- month follow-ups. The ASHA-Health HPV Intervention builds on a highly successful multifaceted US-Indo collaboration of over 10 years, has a high potential for scale-up in India, and engages HPV co-infected WLH in reducing the risk of CC as well as improving their health. The success of this intervention can lead to policy development and future implementation science trials in the prevention of CC among co-infected Indian women.
