Human Papilloma Virus (HPV): Why Clinical Nutrition is Imperative

 

By Dr. Millie Lytle ND, MPH, CNS

The Human Papilloma Virus (HPV) is ubiquitous. Genital HPV is the most common sexually transmitted disease in the United States.  An estimated 6.2 million people are newly infected every year1. More than 100 HPV types have been identified, over 40 of which can infect the genital area, causing warts, cellular abnormalities, and even cancer. HPV is not a single condition; instead, it is an umbrella term for a set of more than 100 types of strains. Of these strains, 40 are responsible for genital warts and viruses that can lead to cervical cancer. There are 4 strains responsible for cellular changes that could eventually cause cervical cancer (HPV 6 and 11, which are less harmful than the aggressive HPV 16 and 18). These same strains lead to anal, throat and mouth cancer in sexually active males and females. This article will cover only the symptoms caused by the cancer-causing HPV strains.

Men are usually silent carriers, meaning they do not know they are spreading this pervasive sexually transmitted disease because they are free of symptoms and there no is no possible testing method. Most women will also never develop any symptoms, because the HPV infection is usually self-limiting – this means that the body’s immune system fights the virus on its own. The Papanicolaou, or PAP test, is a necessary exam for females whereby the physician takes a cellular sample from the cervical tissue for cellular analysis to assess for cellular changes, called cervical atypical or cervical dysplasia. While spotting and pain during sexual intercourse are the most common symptoms, the PAP test is the only way to determine actual risk for cervical changes. Having routine PAP tests reduces a woman’s risk of developing a cancer related to the HPV infection. Diagnoses are staged for severity of cervical dysplasia (Cervical Intracellular Neoplasia 1, CIN2, CIN3 and cancers (Carcinoma in Situ, Invasive Cervical Carcinoma).  But what determines if person develops a persistent HPV infection, or if it clears up on its own?

Despite high vaccine effectiveness3, the prevalence of infections may be rising. Studies show that vaccine compliance is low, possibly due to lack of public trust on the safety of the vaccine (see incidence reports on deaths and adverse events here: http://www.nvic.org).  Data from the American National Health and Nutrition Examination Survey in 2009-2010 found that the prevalence of HPV infections among women is 42.7% in the cervix, and 3.8% in the mouth and throat2. Women with oral HPV infections were 5 times more likely to have a cervical HPV infection as well, which means that HPV infections at these two sites are not independent2.  Thus, overall body health and susceptibility, rather than exposure, might be the issue.

Education and Nutrition may be the missing link. Nutrition and lifestyle factors can play either a positive or detrimental role on an individual’s overall level of health. While there has been massive promotion of the HPV vaccine, the population’s health efforts to promote a healthy lifestyle and diet have been minimal at best. A lack of health information on the risk factors of HPV and prevention and lifestyle strategies to treat it leave the public feeling confused and powerless about their options. While research is behind, there are many risk factors and interventions associated with lifestyle and nutrition that the public ought to be informed of so they know how to best prevent and treat their current situation. 

GET EDUCATED: How to Reduce your Risk of HPV Infections

  • Get tested. Getting examined by the doctor establishes your cervical health.
  • Use protection.  Unprotected intercourse increases risk for developing tissue abnormalities. While cervical cancer is unlikely with condom usage, genital warts can be contacted, as male and female condoms do not cover the entire area.
  • Delay intercourse and be selective. Changing male partners (especially prior to 18 years of age) introduces the virus at a time when the body is still maturing, meaning the cells are most susceptible to viral influences.    
  • Delay childbirth. Giving birth prior to 22 years of age increases risk for cervical dysplasia due to cellular changes in the cervix.                                       
  • Stop smoking. Women who smoke have 2-3 times higher risk for developing cervical abnormalities due to decreased antioxidants and increased free radical damage that lower the immune system’s response to fight the virus.  Results from a large prospective study confirmed that tobacco smoking is a major risk factor for the most severe types of cervical dysplasia (CIN3) as well as CIS, and even the more severe ICC4. Quitting smoking is required for recovery from HPV.
  • Reconsider your Pill. Long-term use of oral contraceptives (over 5 years, as well as other medications such as Midol, Tylenol, and Ibuprofen) may be responsible for nutrient deficiencies of the crucial antioxidants (Folic Acid, Vitamin C and Zinc) needed to protect soft cervical tissues against conditions caused by HPV.
  • Cut down on alcohol. Alcohol damages cells and leaches key nutrients from the body integral for immune health (B1, B12, Folic Acid and Zinc). A link has been established in women who consume two or more servings of alcoholic beverages per day with a persistent HPV infection of the mouth5
  • Fruits, veggies and supplements. Those who eat a poor nutrient diet, meaning insufficient servings of fruits and veggies, are missing key nutrients and therefore are more likely to develop HPV infection.

GET HEALTHY: Nutrients Researched for HPV Infections and Immunity

If you have been diagnosed with abnormal cervical cells or cervical dysplasia, rather than waiting to the next PAP test, why not consult one of InVite’s Naturopathic Doctors or Nutritionists to improve antioxidant protection and boost your immune system? Nutritional programs may include food and supplement suggestions for increasing specific nutrients, as well as improving immunity so the body can fight the virus on its own. Generally, it is especially important to eat lots of fruits and veggies. The Mediterranean Diet is the most researched diet to follow, but any lifestyle that incorporates the following traits will suffice:

  • High nutrient intake. A diet rich with green, yellow, orange, red and cruciferous vegetables has been shown to be the best way to incorporate key nutrients into the diet. When specific antioxidants such as Vitamins A, C, E, folic acid, carotenoids and lycopene are low, HPV is harder to treat.  What’s more, cabbage-family vegetables with natural levels of Indol-3-Carbinol and Sulforaphanes have great cancer-fighting abilities (Don’t eat raw broccoli and raw kale if you have an underactive thyroid).
  • Increase alkalinity and decrease acid, which can cause cancer. You can measure the acidity of your urine using a pH test strip. For more information on Alkalizing your diet, click here .
  • Breathe in salt air and eat from the sea. Seafood contains essential minerals such as iodine, magnesium, calcium, boron, selenium and zinc, which are essential for maintaining a healthy immune system, proper thyroid function, metabolism, and electrolytes. If your whole body is healthier, delicate tissues like your cervix will respond positively.
  • Exposure to the sunshine vitamin. Don’t forget Vitamin D is essential for normalizing immune response. The salt water mineral magnesium is required in order for Vitamin D to aid in proper calcium absorption.
  • Leave junk food behind. Fast food and microwaveable meals are high in sodium, refined sugar, processed white flour, and animal products with hormones and other bad fats. These foods cause inflammation and rob the body of essential nourishment. Inflammation contributes to cancer growth, heightening your risk of developing HPV-related cancer.  

In addition to the diet, there are several key nutrients that have been studied in relation to HPV, cervical dysplasia, and cervical cancer. While there is no guarantee you can recover naturally from cervical cancer, nutrition can be used alone or in combination with medical procedures to improve outcomes and protect one’s response to HPV exposure. Remember, if the body is healthy, HPV and cervical dysplasia will clear on their own. Some nutrients tend to be lower in people with persistent HPV infections, whereas other nutrients have been shown to actually heal cervical tissue. Cervical dysplasia and cancer cells have been shown to respond positively with supplementation of certain nutrients. Here is how to augment specific nutrition to give your immune system the best defense possible to fight the conditions causes by HPV. Inspired by the original protocol by Dr. Tori Hudson, ND, here is a 12-month plan for targeting cervical dysplasia and cancer. Supplement levels will vary in each individual.

Dr. Millie's Plan for Cervical Dysplasia and Cervical Cancer

  • Folic Acid:  Low serum and red blood cell folate are moderately, but not significantly, associated with an increased risk of invasive cervical cancer6. If you are on oral contraception pills, drink alcohol, or take ibuprofen or other pain relievers, you are more likely to have an insufficient supply of folic acid in the body. Consider an extra serving of folic acid to supplement what your medications are depleting – folic acid is essential for healing the delicate tissues of the cervix. Doses required to improve cervical dysplasia outcomes may vary depending on a woman’s age and risk factors.  Several studies have shown that low serum folate levels are linked to cervical dysplasia, and high folate blood levels are linked to the prevention of CIN I (cervical dysplasia).8,9 Improvement in cervical dysplasia outcomes using folic acid supplementation is also well documented10, showing improvement when using up to 10mg per day for 3-6 months.
  • Indol-3-Carbinol, Sulfurophanes and DIM: Studies show that this extract from cabbage or cruciferous family vegetables, 1-3-C and its active form DIM, have the potential to prevent and even treat a number of common estrogen-related cancers.11 In a double blind, placebo-controlled study, 30 patients with biopsy-confirmed CIN II-III (moderate to severe cervical dysplasia) received either a placebo or 200 or 400mg oral 1-3-C daily for 12 weeks. None of the 10 placebo patients had complete regression of CIN, whereas four out of eight patients in the 200 mg per day group and four of nine in the 400 mg per day group had complete regression.12 1-3-C is easily available over the counter to supplement a diet that contains 4-5 servings of cruciferous vegetables a day.
  • Depending on the quality of your diet and lifestyle, a multivitamin and mineral supplement for women that includes antioxidants such as Vitamins A, C, E, CoQ10, Lycopene, Lutein, Selenium and Zinc may be essential for good cervical health. One study found that blood levels of CoQ10 and Vitamin E were significantly lower in patients with diagnosed CIN cervical cancer than in controls.13 Another study revealed that levels of CoQ10 from cervical epithelial cells themselves were significantly lower in women diagnosed with CIN.14 Women with low levels of these two antioxidants may have increased risk for the development of cervical dysplasia, and proper supplementation corrects these nutrient deficiencies.
  • Vitamin C in any form is one of the body’s main antioxidants. It also works to re-circulate Vitamin E, another one of the body’s most important antioxidants. While it’s known that women with cervical dysplasia have low blood levels of Vitamin C15, Vitamin C’s anti-cancer effects are numerous. One study showed that women with high intake of dietary Vitamin C had a lower risk of cervical dysplasia.16 Another study of Korean women looked at 58 cases of CIN cervical cancer and compared them with 86 women with normal PAP test results – the cancer group had significantly lower blood levels of Vitamin C than the control group.17 The accumulation of these results show that Vitamin C plays a definite role in the prevention and treatment of cervical dysplasia. Personally, I recommend a minimum of 2000mg per day.
  • Green Tea: Green tea is well-known for its ability to fight cancer. Epigallocatechin-3-gallate (EGCG) is the most powerful polyphenol antioxidant from green tea. It is known to impede the epidermal growth factor receptor, an agent needed for cervical cell growth. A recent study looked at 51 women with HPV-positive cervical dysplasia and divided them into 4 groups, compared to 39 controls. The study used the following method: 1) Green tea ointment was applied locally to 27 patients twice a week. 20 out of 27 patients under ointment therapy showed a response. 2) One standardized EGCG capsule was taken every day for 8 to 12 weeks. Six out of eight patients under green tea ointment plus capsule therapy showed a response. Six out of 10 patients under EGCG capsule therapy alone showed a response. Overall, a 69% response rate was noted for treatment with green tea extracts, compared with a 10% response spontaneous improvement rate in the controls. A positive response meant an improvement in cervical dysplasia staging.18 Up to 900mg of EGCG per day is safe.
  • Coriolus Versicolor (Reishi, Shiitake, Cordyceps and Coriolus) is an immune mushroom commonly used for its health-boosting and disease fighting properties. As a known immune-modulator, it has been studied for its immune-enhancing properties in cancer patients undergoing chemotherapy. It has been studied for its ability to improve immune response to HPV and to reverse the early stages of cervical cancer.19 In a year-long Portuguese study, Coriolus versicolor cleared high-risk strains of HPV known to cause cervical dysplasia and cervical cancer in 39 women. All of the women had the equivalent of CIN 1 or 2. After one year, 9 of 10 women who supplemented with 3000mg Coriolus versicolor tested negative for HPV, compared with just 1 of 12 placebo women. In addition, 13 of 18 Coriolus patients reverted to normal PAP results, compared with 10 of 21 non-supplemented women.
  • Resveratrol: In one in vitro study, Resveratrol treatment (150-250 µmol/l) applied for 48 hours increased cell-cycle arrest on HPV18 and HPV16 positive cervical cancer cells.21 Furthermore, a lower dose of resveratrol (50 µmol/ produced a similar effect, suggesting that this effect is not necessarily dose-dependent and that even a low dose of resveratrol treatment changes the expression of the cancer gene on both HPV18 and HPV16-positive cells. This study shows promise that that resveratrol uses different mechanisms to induce the killing of cervical cancer cells.

Topical treatments are important as well. In addition to this vitamin protocol, there is a treatment option involving a rotating series of vaginal suppositories for women with moderate or severe cervical dysplasia. These suppositories would include a combination of antiviral, escharotics and therapeutic herbs, enzymes, and vitamins to treat and heal the local site. These suppositories are capable of killing the virus and healing the local area, and unlike the LEEP procedures, are non-scarring. Suppositories must be performed or taught by a trained alternative health professional.
