Man receives kidney transplant, then body becomes riddled with worms, doctors say
The 61-year-old man received a new kidney from a deceased donor after being diagnosed with 'nephrosclerosis-related end-stage kidney disease,' or chronic high blood pressure that causes hardening of the walls of arteries in the kidneys, according to a June 18 case report published in the Case Records of the Massachusetts General Hospital.
The transplant was successful and the man was sent home with care instructions just four days later, doctors said.
Six weeks later, the man attended a follow-up visit where doctors saw a slightly elevated creatinine level and hyperglycemia, the former an indicator of kidney function and the latter indicative of diabetes, according to the report. He was sent home with a weekly injection of semaglutide, the active ingredient in drugs like Ozempic and Wegovy.
Then his health took a turn.
Successful transplant turns critical
A week later, the 61-year-old was scratched by his cat and his ankle began to swell, doctors said. He started to feel tired and nauseated the next week, then started throwing up and drinking excessive amounts of water, according to the case report.
He was admitted to the hospital again, and over the next ten days, his heart rate increased significantly, his breathing decreased until he needed to be put on a ventilator, doctors said.
Hoping for answers, his medical team turned to his previous medical history for something that might have been missed.
The 61-year-old had been on the transplant list for 6 years, according to the report, and he had diabetes and spent much of his life as a smoker.
He had lived in New England his entire life and hadn't traveled. He enjoyed gardening, and had healthy cats and a dog at home with his wife.
Then the rash appeared.
Purple and blotchy, the rash stretched across his stomach as his abdomen grew to become large and hard, and normal bowel sounds were absent, according to the report.
By this point, the man was described as 'critically ill,' and because the man was on immunodepressants to help his body transition to the new organ, doctors compared the man's symptoms to other examples of infections.
'Given that the patient's presentation is not consistent with a drug reaction or rejection of the kidney allograft, I think that the most likely explanation for his critical illness is a disseminated parasitic infection,' Camille N. Kotton, an infectious disease and transplant expert, wrote in the report.
The man was diagnosed with 'donor-derived disseminated strongyloidiasis,' or an infection caused by parasitic roundworms, doctors said.
What are roundworms?
The roundworms, also called threadworms, can infect humans directly, but can also be passed to humans through contact with monkeys or domestic dogs, according to the Centers for Disease Control and Prevention.
In this man's case, the source of the infection was his new kidney, donated from someone who lived in the Caribbean before their death and who had not been tested for strongyloides before the donation, according to the case report.
Between 2008 and 2017, the Organ Procurement and Transplantation Network, the group that oversees organ donation in the United States, reported 14 out of 10,000 organ donations could result in disease transmission, or about 0.14% of donations, doctors said.
'Unfortunately, many of these events are varied and unexpected, involving a long list of pathogens ranging from viruses to bacteria and parasites,' doctors wrote. 'Although we have contemplated how to avoid such transmissions, many seem unavoidable and result in undesirable circumstances.'
The man was successfully treated with ivermectin, an antiparasitic drug, and doctors contacted the organ board to see if any other patients had received organs from the same donor, according to the report.
A 66-year-old man had received the donor's other kidney, doctors said, and his medical team was contacted to begin treatment for the infection after he had already been showing similar symptoms.
Both men fully recovered and their transplants were successful, according to the report.
The medical team includes Kotton, Rory L. Cochran, Alan M. Sanders, Kassem Safa and Maxwell T. Roth.

Formerly bankrupt weight-loss company makes a comeback
When it comes to things that most concern Americans about their health, weight loss is often at the top of the list. While America doesn't have the top obesity rate in the world, it does rank high on the list. More than 45% of Americans are obese. But the issue is bigger than just in the country - the worldwide rate of adult obesity has more than doubled since 1990, per the World Health Organization. Don't miss the move: Subscribe to TheStreet's free daily newsletter Attempts to solve this problem have spawned a thriving diet industry, always promoting the next pill, diet plan, or weight-loss gimmick to those desperate to attain better health. These approaches have all propelled the U.S. weight-loss market to grow over the decades, but the birth of GLP-1 drugs such as Ozempic sent it to new heights in 2023, with a market value of $90 billion. Related: One of Oprah's favorite things prepares for Chapter 11 bankruptcy It's a profitable market, but also an overcrowded one, and trying to get people's attention and stay on the cutting edge of what appeals to consumers presents a daunting challenge that businesses must continually navigate. Now, after one of the best-known names in the industry seemed to be on the edge of extinction, it's making a turnaround that few could have predicted - and with a new focus on a long-ignored women's issue. After declaring Chapter 11 bankruptcy in May of 2025, once-giant WeightWatchers (rebranded to WW beginning in 2018) admitted its $1.5 billion in debt was too big of a burden to continue to bear. The bankruptcy process would eliminate that debt, the company said, and it expected to reemerge as a publicly traded company. "The decisive actions we're taking today, with the overwhelming support of our lenders and noteholders, will give us the flexibility to accelerate innovation, reinvest in our members, and lead with authority in a rapidly evolving weight management landscape," said CEO Tara Comonte in a release at the time. Related: WeightWatchers takes drastic step to exit bankruptcy WeightWatchers made its debut in the '60s, at a time when diet and portion control were a focus, and enjoyed many decades of success. The company also got a significant boost when Oprah partnered with it in 2015. WeightWatchers has now emerged from that bankruptcy with a new focus: helping middle-aged women struggling with all stages of menopause, from peri to post. The new program will offer access to prescription treatments such as hormone replacement therapy and also help women connect with resources for behavioral and nutritional support, WeightWatchers said. The company also named Dr. Kim Boyd as its new chief medical officer. Boyd has worked in leadership at One Medical, Calibrate, Caire, Galileo, and Nurx in the past and has co-founded or scaled multiple consumer health companies. Menopause care has been a hot topic as of late, with high-profile actresses such as Naomi Watts founding new companies to support women going through it. After Watts experienced early menopause at 36, she founded Stripes Beauty, a brand that sells products aimed at women in all stages of the life change. WW's new angle could provide the first large-scale platform for menopausal women, which could take advantage of a once-taboo topic that's slowly gained more attention in recent years.

Gary Harm Reduction suffers funding cuts, board member talks worries
When one local advocate thinks about changes coming to budgets of local nonprofits, he feels a mixture of sadness and anger. As federal funding changes roll in, organizations nationwide learn to continue offering services with fewer resources. Gary Harm Reduction is one of those. Executive Board Member Robert Bailey said the organization had about $500,000 in federal and state grants at the beginning of the year, but with changes, Gary Harm Reduction is seeing about $50,000 in funding. 'Some of it is like the government slashed (diversity, equity and inclusion) grants and (LGBTQ+) grants, and deliberately targeted that,' Bailey said. 'They've also targeted HIV grants because that's apparently not a priority.' Gary Harm Reduction is a local grassroots organization that was founded in 2020, according to its website. It provides the opioid antidote naloxone, known by its brand name Narcan, advocacy for substance users and people in recovery, and overdose prevention education. The organization is entirely volunteer and has distributed more than 5,000 Narcan kits, according to its website. Indiana's overdose death rate is 41 per 100,000 individuals, according to the Centers for Disease Control and Prevention. Lake County has the second-highest overdose rate in the state, according to Post-Tribune archives. 'The Trump administration and Gov. (Mike) Braun are targeting the most vulnerable people and hurting them,' Bailey said. 'I personally have lost many friends to opioid overdose. … I am not exaggerating when I say that these cuts will kill people. The U.S. Fiscal Year 2026 budget includes cuts for HIV care, treatments, programs, prevention and surveillance at the CDC, housing and other programs, according to the HIV and Hepatitis Policy Institute. The cuts amount to more than $1.5 billion. 'While we appreciate the need to improve government efficiency and look forward to having those discussions, it is not efficient to decimate the nation's established and successful programs to prevent an infectious disease,' said Carl Schmid, executive director of the HIV and Hepatitis Policy Institute, in a statement. 'This will only result in an increase in costly lifetime chronic illnesses and run completely contrary to what the administration has been promoting. We believe Congress understands the critical federal role in preventing infectious diseases, such as HIV and hepatitis, and the serious implications and consequences to the health of our country if these programs are not adequately supported.' In January, President Donald Trump's organization also announced diversity, equity and inclusion cuts in an executive order, calling them 'radical and wasteful.' The cuts have led to billions of dollars in savings, according to the White House. Trump's federal budget also made various cuts to LGBTQ+ programs, according to the Human Rights Campaign, which could equal about $2.67 billion nationwide. 'This budget is more than cuts on a page — it's a direct attack on LGBTQ+ lives,' said Matthew Rose, senior public policy advocate, in a news release. 'Trump is taking away life-saving health care, support for LGBTQ-owned businesses, protections against hate crimes, and even housing help for people living with HIV. Stripping away more than $2 billion in support sends one clear message: we don't matter. But we've fought before, and we'll do it again — we're not going anywhere.' Since learning how drastic the changes will be, Bailey said Gary Harm Reduction has been 'in damage control mode.' The organization's executive director has talked about foregoing a salary to help make up for missed funding, Bailey said. Executive Director Kristen Martin was unavailable to comment Tuesday. Board members have sent messages to local organizations that might be able to help with funding, Bailey said. A major concern for Gary Harm Reduction is keeping its physical office at West Ridge Road near Calumet New Tech High School in Gary. Having a physical location is 'incredibly important' for Gary Harm Reduction, Bailey said. 'There's a relatively large unhoused population in that area,' he said. 'It's helpful to have that, especially with things like regional health care coming in and doing doctor's visits with people.' In addition to money, board members have also asked for donations of supplies needed, such as blankets or kits for those who receive services. The city of Gary installed a Narcan vending machine at the Adam Benjamin Jr. Metro Center on March 21 to help with Narcan distribution, which is a nasal spray that helps rapidly reverse the effects of an opioid overdose. Gary representatives could not immediately respond to a request for comment Tuesday about whether the city's services will be affected by federal and state funding cuts. As Gary Harm Reduction looks to the future, Bailey can only hope that solutions are possible and people will help those struggling with drug use in the community. Bailey hopes that federal and state government officials will also see the importance of harm reduction programs. 'The problem with drug use is that it tends to fly under the radar,' Bailey said. 'We don't like to talk about it as a society. It's very stigmatized, so these people are going to be dying in silence, and people don't know this harm is happening. They need to know.'

Colon cancer is spiking in young adults. Scientists are blaming the American diet
Rates of colorectal and other gastrointestinal cancers are rising in Americans under the age of 50, researchers said Tuesday. They may know why. An increased risk of early-onset gastrointestinal cancers is associated with obesity, which is also rising in the U.S. That's what scientists say is a 'leading theory' for the surge - noting a 2019 study that found women who were considered obese had nearly double the risk of developing early-onset colorectal cancer. Close to half of all U.S. adults are predicted to be obese by 2030, according to research released the same year. The chronic condition can cause inflammation and higher levels of insulin that increases peoples' risk of getting cancer, including several types of gastrointestinal cancers, according to the Centers for Disease Control and Prevention. Other risk factors include smoking, drinking alcohol, eating a Western-style diet and non-alcoholic fatty liver disease. Earlier this year, new research pointed to the impact of a toxin in the gut, known as colibactin, that can inflict DNA damage on colon cells that leads to the development of cancer. Colibactin is produced by the bacteria E. coli, which is often responsible for foodborne illness. As of now, the specific cause remains unclear but the U.S. is not alone, researchers said. 'The incidence of GI cancers in adults younger than age 50 is rising globally,' explained Boston's Dana-Farber Cancer Institute oncology fellow Dr. Sara Char. In the U.S., scientists found that early-onset cases have shown a 'marked increase' in both American men and women since the mid-1990s. In comparison to American adults born in 1950, those born in 1990 have twice the risk of developing colon cancer and four times the risk of developing rectal cancer, the researchers found. Furthermore, early-onset colorectal cancer has become the leading cause of cancer-related deaths in U.S. for men under 50. For women in the same age group, it's the second-leading cause of cancer-related deaths. Colorectal cancer, the most common type of gastrointestinal cancer, also affects Black, Hispanic, Indigenous, and Asian people disproportionately. These and other related findings signal a worrying shift — and potentially a need for updated treatment practices, the researchers noted. Patients with early-onset colorectal cancers often experience delays in diagnosis because neither doctors, nor their patients, suspect cancer and doctors are more likely to diagnose patients when they are at advanced stages of the disease. Younger patients are more likely to receive aggressive treatment, 'often without a survival advantage,' they said. Colorectal cancer is the third-leading cause of cancer-related deaths in American men and the fourth-leading cause in women. Overall, it's the second most common cause of U.S. cancer deaths, and the American Cancer Society says it's expected to cause about 52,900 deaths this year. The researchers pointed out that younger patients are more likely to experience financial hardship because of their diagnosis and problems with body image and mental health, as well as a worse quality of life. 'Ongoing research efforts investigating the biology of early-onset GI cancers are critical to developing more effective screening, prevention, and treatment strategies,' Char, the paper's lead author, said. The paper was published by Oxford University Press in the journal BJS.
