暴露在阳光下的牡蛎蘑菇有助于患者对抗肺结核 Sun-exposed oyster mushrooms help patients fight tuberculosis


巴尔的摩(2019年6月9日) – 结核病(tuberculosis – TB)仍然是低收入国家中最致命的传染病之一,每年约有160万人死于此病。在一项新研究中,研究人员表明,暴露在阳光下的牡蛎蘑菇(oyster mushrooms)提供了一种现成的维生素D来源,可以帮助结核病患者通过改善免疫反应更好地对抗结核药物作出反应。

德国霍恩海姆大学的博士研究员TibebeSelassie Seyoum Keflie说:“由于抗药性菌株的出现,结核病变得越来越难以抗争,因此迫切需要能够支持一线药物的新疗法。” “这种维生素D的来源是低收入国家的理想选择,因为蘑菇可以很容易地以安全,低成本,易于复制的方式分发和管理。”

与Hans Konrad Biesalski一起完成研究的Keflie将于2019年6月8日至11日在巴尔的摩举行的营养2019年美国营养学会年会上展示该研究。



“这是第一次来自暴露在阳光下的牡蛎蘑菇中的维生素D被证明是结核病的潜在辅助疗法,”凯夫利说。 “通过教育推广,有可能教会结核病患者在烹饪前短时间照射自己的蘑菇。”

Sun-exposed oyster mushrooms help patients fight tuberculosis

Bread containing the low-cost mushrooms increased vitamin D levels and boosted immune response of TB patients

American Society for Nutrition

Baltimore (June 9, 2019) – Tuberculosis (TB) remains one of the deadliest infectious diseases in low income countries, with around 1.6 million people dying of the disease each year. In a new study, researchers show that sun-exposed oyster mushrooms offer a readily available source of vitamin D that can help TB patients respond better to anti-TB drugs by improving immune response.

“TB is becoming more difficult to fight due to the emergence of drug-resistant strains, creating an urgent need for new treatments that can support first-line drugs,” said TibebeSelassie Seyoum Keflie, a doctoral fellow at University of Hohenheim, Germany. “This source of vitamin D is ideal for low income countries because mushrooms can easily be distributed and administered in a safe, low-cost, easy-to-replicate manner.”

Keflie, who performed the research with Hans Konrad Biesalski, will present the research at Nutrition 2019, the American Society for Nutrition annual meeting, held June 8-11, 2019 in Baltimore.

Studies have shown that vitamin D induces the body to form an antimicrobial compound that attacks the bacterial cause of TB. Although sun exposure can boost a person’s vitamin D levels, it must be obtained through diet when sun exposure is scarce.

The researchers used oyster mushrooms because they offer a cheap, safe and readily available source of vitamin D that is easily absorbed by the body. Although fresh oyster mushrooms contain almost no vitamin D, the fungus produces it the after exposure to sunlight much like the human body.

“This is the first time that vitamin D derived from oyster mushrooms exposed to sun has been shown to be a potential adjunctive therapy for TB,” said Keflie. “With educational outreach, it might be possible to teach people with TB to irradiate their own mushroom for a brief period before cooking.”

For the study, the researchers gave a group of TB patients sandwich bread containing 146 micrograms of vitamin D from sun-exposed oyster mushrooms every morning during the first four months in which they received an anti-TB drug.

At the end of the four months, 95 percent of patients receiving the fortified bread were classified with the lowest TB severity score on a scale of 1 to 5. The treatment group had significantly higher vitamin D levels compared to patients not receiving the bread, with more than a third of them no longer showing a vitamin D deficiency. The researchers also observed that patients who consumed the fortified bread had significant improvements in immunological responses over the four months.

The researchers plan to carry out additional investigations on the interactions of vitamin D and immunological responses in larger and more diverse groups of TB patients. They are also developing different mushroom drying methods to determine how to achieve the highest levels of vitamin D.

TibebeSelassie Seyoum Keflie will present this research on Sunday, June 9, from 3:45 – 4 p.m. in the Baltimore Convention Center, Room 319/320 (abstract). Contact the media team for more information or to obtain a free press pass to attend the meeting.
