In looking back over my last 12 blog posts here at Global Health TV, it is clear that 2017 was a year of progress, near triumphs and threats to global health.

In September, I reported that great progress has been made against diseases and health conditions that kill us (like respiratory infections, diarrhea, neonatal preterm deaths and communicable diseases like AIDS and malaria) while new threats had emerged  that are generally less fatal — things like obesity and mental illness.

In particular, we have made progress against communicable diseases but now face a rising tide of non-communicable diseases (NCDs) like cancer, diabetes, hypertension and cardiovascular diseases, as I wrote at the beginning of 2017.  Cancer is growing almost everywhere in the world. For example, cervical cancer causes over 500,000 new cases every year, even though vaccination, early screening and treatment of precancerous lesions can prevent most cases.

10 lessons we've learned from AIDS that we can apply to chronic diseases

Communicable diseases like HIV/AIDS and malaria have taken a terrible toll on Kenya and other African countries over the last 20 years. In 2010, an estimated 51,000 Kenyans died from AIDS but that number has declined steadily, to 36,000 in 2016. Kenya is now considered an HIV success story. The same is true in many other countries.

Now there is a new epidemic of non-communicable diseases (NCDs) that is rising just as the world is starting to get a handle on communicable diseases, according to the Institute for Health Metrics and Evaluation. The Institute reports that the largest contributors to the loss of healthy life are now high blood pressure, smoking, high blood sugar and excess body weight.

But Dr. Samuel Mwenda, who knows a thing or two about both epidemics, believes there are lessons we have learned in the fight against communicable diseases that can now be applied to NCDs. Mwenda is general secretary and CEO of the Christian Health Association of Kenya (CHAK), a network of Protestant health facilities in Kenya. CHAK now supports 46,000 people living with HIV with antiretroviral therapy, representing about 9 percent of the total number of patients nationally.

In 2015, CHAK turned its attention to NCDs: With the support of Novartis Access, it began offering a portfolio of 15 products to treat cardiovascular disease, diabetes, respiratory illness and breast cancer at a price to governments, NGOs and other institutional customers not to exceed $1.00 per treatment per month. Since then, Novartis Access has also started working in Cameroon, Ethiopia, Pakistan, Rwanda and Uganda.

Over 16 years ago, Sally Kwenda survived colon cancer and HIV, and then lost her husband and two children to AIDS-related illnesses.

“Just when I thought I was done with the hurt and the pain, I was diagnosed with stage II cervical cancer,” she recalls. “Many of those I have met on this journey have either passed away or are worse off than me. Many of them got their diagnoses when it was too late to change the tide. Yet cancer does not have to be a death sentence. My experience reveals that cancer is curable.”

Cervical cancer is the most common cancer among women in Sally’s home country of Kenya as well as in 38 low- and middle-income countries, mainly in sub-Saharan Africa, according to the American Cancer Society (ACS).

The reasons for the high rates of cervical cancer in Kenya, according to Deborah Olwal-Modi, executive director of the Kenya Cancer Association, include lack of knowledge and awareness, inadequate facilities for prevention and treatment, economic barriers, and co-morbidity of cervical cancer and HIV/AIDS. For example, almost all women (97 percent) do not know that a virus causes cervical cancer, according to a new study among women in major Kenyan cities.

As infectious disease falls, chronic disease increases; possible solutions emerge

As 2017 begins, we celebrate the fact that many diseases of developing countries have been significantly weakened. The numbers of people suffering from HIV, malaria and tuberculosis are in decline. Children are healthier and living longer.

But as these communicable diseases wane, non-communicable diseases (NCDs) wax (like cancer, diabetes, cardiovascular and chronic respiratory diseases).

This was hammered home by the Institute for Health Metrics and Evaluation (IHME) of the University of Washington which, just in the last two months, released three new reports that provide further evidence of this trend:

• Almost 20% of global deaths in 2015 were linked to elevated blood pressure, according to the latest Global Burden of Disease study. The number of people in the world with high blood pressure, including hypertension, has doubled in the past two decades, putting billions at increased risk for heart disease, stroke and kidney disease.
• Cancer is growing almost everywhere in the world but the greatest increase between 2005 and 2015 occurred in the poorest countries that are least equipped to deal with it, according to a new analysis.
• 30% of all deaths from diabetes worldwide occur in the poorest countries bringing a double burden of disease – from communicable and non-communicable disease – to many countries in Africa, according to a new IHME report. Women often bear most of the burden.

Drug companies test out new strategies for improving access to treatment in poor countries

When Harald Nusser first walked into the waiting room of the hospital in Addis Ababa, Ethiopia and saw so many people suffering in the late stages of cancer, without even basic palliative care, he couldn’t believe his eyes.

“Some of them had so much pain, they were hitting their heads against the walls, to balance the pain they had inside with a different type of pain,” Nusser said.

A physician who works for one of the world’s biggest drug companies, he was especially affected by the women he saw suffering from breast cancer: “It was absolutely breath-taking to look at those women and realize that 99 percent of them would be dead in a year.”

For decades, the global health community has been focused mostly on communicable diseases like AIDS and malaria. Many like Nusser say the changing disease burdens of lower-income countries require more attention to noncommunicable diseases like cancer. Yet this isn’t happening, and most health systems in poor countries are not equipped to meet the need.

“When I saw this for the first time, I said to myself, you have to do something to change this,” Nusser said. That was in 2013 and, at Novartis, he is today doing something to try to change the situation.

Stymied by Less Smoking in Richer Countries, Big Tobacco Shifts Focus on Developing Countries

Between 1990 and 2009, cigarette consumption decreased by 26% in Western Europe, but in Africa and the Middle East, it increased 57%, according to the American Cancer Society (ACS). In response, many of these developing countries are stepping up their efforts to fight tobacco with new laws and restrictions. Big Tobacco is using its deep pockets to finance creative attempts to circumvent those laws.

The problem is so daunting that ACS named rising use of tobacco in developing countries as one of it “Three Top Cancer Challenges of the 21^st Century” earlier this month when it observed World Cancer Day. Comedian John Oliver covered the issue very well in this segment from his HBO show “Last Week Tonight.”

An estimated 8 million of the 14.1 million new cancer cases diagnosed in 2012 occurred in developing countries with 82% of the world’s population, according to Global Cancer Facts & Figures, 3^rd Edition. Smoking causes at least 12 types of cancer, according to the U.S. Surgeon General, and accounts for a fifth of all global cancer deaths. Tobacco use is the cause of nearly 6 million premature deaths annually, notes the report.

Cancer Rises in Africa, A Continent Ill-Prepared to Handle It

"Thank God I have AIDS and not cancer, because that would be a death sentence," an HIV-positive woman told Ann Kim, a freelance journalist on a fellowship from the International Reporting Project, in a clinic in Botswana earlier this year.

Botswana, a well-off country by African standards, has an adult HIV prevalence of 24 percent, the second highest in the world, and a health system well-prepared for dealing with it, but not cancer.

In Togo, Dr. Kokou Agoudavi, the head of non-communicable diseases at the Ministry of Health, told me that Togolese cancer patients sometimes sell their houses or fields to pay for cancer treatment, which is not available in-country. They have to go to neighboring Ghana, if they can afford it. He said this often happens in the late stages of cancer, when survival rates are low.

U.S. committed to fighting NCDs, but not financially

Non-communicable diseases (NCDs) are now the leading cause of deaths in the world, killing more than 36 million people in 2008 (63% of the total). Cardiovascular diseases were responsible for 48% of these deaths, cancers 21%, chronic respiratory diseases 12% and diabetes 3%, according to a report published this week by the World Health Organization. 

But NCDs are definitely not “rich country”  diseases anymore: 80% of those deaths took place in low- and middle-income countries. 

And it is getting worse. This week the Washington Post reported: 

“The world is facing a growing avalanche of death from heart attack, stroke, cancer, emphysema and diabetes, with many of the victims working-age people in poor countries. Governments and individuals could intervene to prevent up to half those deaths, but no country is doing all it could.”

The economic impact of all that death and disability is profound. Just take cancer, the second leading cause of NCD deaths. Last year, the American Cancer Society reported that the total economic impact of premature death and disability from cancer worldwide was $895 billion, representing 1.5% of the world’s gross domestic product. That’s enormous, and it’s just one of the four main NCDs.

What to do about the newly-discovered worldwide epidemic in a time of fiscal austerity and, in the U.S., hostility to new social spending, was one of the main issues discussed at an event last week at the Center for Global Development “U.S. Outlook for the Non-Communicable Disease Summit.”
