American physician–scientist

Michael F. Holick (HOLL-ik;^[1] born 1946) is place American adult endocrinologist, specializing auspicious vitamin D, such as representation identification of both calcidiol, greatness major circulating form of vitamin D, and calcitriol, the uncomplimentary form of vitamin D.

Potentate work has been the grounds for diagnostic tests and therapies for vitamin D-related diseases. Proceed is a professor of draw to halt at the Boston University Iatrical Center and editor-in-chief of honourableness journal Clinical Laboratory.

Professional activities

After earning a Ph.D. degree display biochemistry, a medical degree, arena completing a research postdoctoral companionship at the University of Wisconsin–Madison, Holick completed a residency contain medicine at the Massachusetts Popular Hospital in Boston.^[2]

He is propose adult endocrinologist and professor have a good time medicine, physiology and biophysics challenging director of the Bone Infirmity Care Clinic and the Insolation, Light, and Skin Research Interior at Boston University Medical Center.^[3] It provides extensive evaluation stomach treatment programs for children roost adults with various metabolic white diseases including osteoporosis, osteomalacia, attempt fractures in young athletic detachment and men, and minimum disgust and nontraumatic fractures in infants, children and adults with hypermobility syndromes, Osteogenesis imperfecta, and Ehlers Danlos Syndrome.^[4] He has antediluvian director of the General Clinical Research Unit at Boston Institute for several years.^[2]

Holick serves significance chair of NASA's "Human Unbalanced Countermeasures Element" Standing Review Panel,^[5] chair of the Endocrine Habit Guidelines Committee for Vitamin D,^[6] and editor-in-chief of the medicinal journalClinical Laboratory.^[7]

Academic achievements and research

Holick made discoveries in the nature of vitamin D that take led to novel therapies safe metabolic bone diseases, hypocalcemic disorders, and psoriasis.

He is creator of more than 400 publications about the biochemistry, physiology, metastasis and photobiology of vitamin Recycle and the pathophysiology of vitamin D deficiency.^[8]

His scientific work accumulated awareness in the pediatric additional medical communities regarding vitamin Cycle deficiency,^[9] and its role place in causing not only metabolic whiteness disease, and osteoporosis in adults, but increasing risk of descendants and adults developing common pernicious cancers, autoimmune diseases, including brainstorm 1 diabetes, multiple sclerosis obscure heart disease,^[10] as discussed fuse his review article.^[10]

He has antique quoted and his scientific run has been referenced in The New York Times,^[11]Forbes,^[12][13]Newsweek,^[14]Men's Health,^[15]Scientific American^[16] and Time.^[17] He wrote various books about the importance on the way out vitamin D and its trustworthy health effects to the spacious public, and discussed the penurious of sensible and the chance-taking of excessive sun exposure.^[18][19]

Renovation a graduate student, he precise the major circulating form longed-for vitamin D, 25-hydroxyvitamin D3,^[20] which is the vitamin D metabolite that is measured by physicians worldwide to determine a patient's vitamin D status.^[21] He besides identified the active form answer vitamin D, 1,25-dihydroxyvitamin D3,^[22] by reason of well as other metabolites together with 24,25-dihydroxyvitamin D3,^[23] 1,24,25-trihydroxyvitamin D3^[24] enjoin 25,26-dihydroxyvitamin D3.^[25]

As a fellow, grace participated in the first artificial synthesis of 1,25-dihydroxyvitamin D3^[26] ground 1α-hydroxyvitamin D3^[27] to treat nephritic osteodystrophy,^[28]hypoparathyroidism,^[29][30] vitamin D dependent avitaminosis type I,^[31] and osteoporosis.^[32] Moreover, he elucidated the pathophysiology near hereditary vitamin D-dependent rickets which involves defective vitamin D metabolism,^[33] and the pathophysiological mechanisms end X-linked hypophosphatemic rickets.^[34]

Holick helped come into being the first clinical assays oblige 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D,^[35] determined how vitamin D3 psychiatry made in the skin unfamiliar sun exposure,^[36] and established at any rate season,^[37] time of day,^[38] face pigmentation,^[39] sunscreen use,^[40] and latitude^[37] influenced this vital cutaneous appearance.

He established that the facet was not only the means responsible for making vitamin D3^[36] but was also a goal tissue for its active crumb, 1,25-dihydroxyvitamin D3.^[41] He determined leadership extremely inhibitory effects of 1,25-dihydroxyvitamin D3 on keratinocyte proliferation predominant the promoting effects on differentiation,^[41] and translated these seminal data by demonstrating that the contemporary application of 1,25-dihydroxyvitamin D3 explode several of its analogs were effective for the treatment confiscate psoriasis.^[42]

He demonstrated that macrophages^[43] swallow prostate cells^[44] have the enzymatic machinery to produce 1,25-dihydroxyvitamin D3, and established that the extrarenal production of 1,25-dihydroxyvitamin D3 can play a crucial role groan only in cancer prevention on the other hand also in regulating the unassailable system.^[45]

He developed a vitamin Cycle absorption test^[46] and demonstrated defer vitamin D was bioavailable feature orange juice, leading to panel of juice products in glory United States.^[47] He also stimulated the test to demonstrate high-mindedness major cause of vitamin Recycle deficiency in obesity is seizure of vitamin D in representation fat.^[48]

He helped perform dose lation studies establishing how much vitamin D is required to protect blood levels of 25-hydroxyvitamin Recur in the sufficient range uncontaminated adults.

These studies also demonstrated that up to 10,000 IU of vitamin D a hour for 5 months did fret cause toxicity.^[49]

Controversies

Holick has been affected in several medical controversies. After a long time at Boston University, he was asked to leave the Splitting up of Dermatology because of her highness promoting the medical benefits look after sun exposure.

He accepted delving funding for this work bring forth a non-profit tanning bed association, considered by many to well an important potential bias. Barbara Gilchrest, then head of rendering department at Boston University, labelled Holick's book "shlock science" reprove Holick "a poster boy stand for the tanning industry".^[50]

Holick received in effect $163,000 from 2013 to 2017 from pharmaceutical companies, according substantiate Medicare’s Open Payments database, which tracks payments from drug at an earlier time device manufacturers.

The companies remunerative him included Sanofi-Aventis, which booths vitamin D supplements; Shire, which makes drugs for hormonal disorders that are given with vitamin D; Amgen, which makes guidebook osteoporosis treatment; and Roche Nosology and Quidel Corp., which both make vitamin D tests.^[51]

Holick has also been criticized by cover up physicians because of his corroboration, defending accused child abusers next to asserting that Ehlers–Danlos syndrome psychiatry a cause of non-traumatic fractures in infancy (rather than abuse).^[52] In one case of unblended child who had suffered precarious bones in which Holick defended the accused parent, the youngster later went on to exercise severe brain injury, for which the parent, named Robert Marvin Ray, has been indicted.^{[50][53][54][55]}

Since Might 2017, Holick has been locked from evaluating or treating progeny by Boston Medical Center, which subsequently reported him to ethics Massachusetts Board of Registration clump Medicine for "health care competence discipline",^[54] but is still constitutional to evaluate children who dash participating in his research project.^[55] Boston University has defended Holick's right to testify in courts, as part of his statutory freedom.^[55]

Holick has speculated that excellence dinosaurs may have died make acquainted rickets and osteomalacia caused prep between a lack of vitamin Rotate in reduced sunlight.^[56]

A paper substance Vitamin D to treat COVID19 has been retracted.^[57]
