There were tragic episodes, such as the attempt to save Pope Innocent VIII (1432-1492), who was on the verge of death as a result of a severe kidney disease. With no other alternatives, his doctors convinced him to drink human blood.<\/p>\n<p>As the story goes, albeit with no proof or details, three 10-year-old boys offered to donate their blood to the pope, in exchange for a ducat coin. The first died after they removed his blood, but the pope showed a slight improvement. Encouraged, the doctors called upon the second donor, removed less blood than they did from the first, but this time the pope ran a high fever, his kidneys stopped working, and he died. The third boy did not need to donate blood, but also died soon after from anemia, which at the time had no diagnosis or adequate treatment.<\/p>\n<div id=\"attachment_540374\" style=\"max-width: 1150px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-540374 size-full\" src=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-seringa-jube-2024-07-1140.jpg\" alt=\"\" width=\"1140\" height=\"687\" srcset=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-seringa-jube-2024-07-1140.jpg 1140w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-seringa-jube-2024-07-1140-250x151.jpg 250w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-seringa-jube-2024-07-1140-700x422.jpg 700w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-seringa-jube-2024-07-1140-120x72.jpg 120w\" sizes=\"auto, (max-width: 1140px) 100vw, 1140px\" \/><p class=\"wp-caption-text\"><span class=\"media-credits-inline\">Santa Casa de S\u00e3o Paulo Museum - Reproduction L\u00e9o Ramos Chaves\u2009\/\u2009Revista Pesquisa FAPESP<\/span>Jub\u00e9 syringe, imported from France<span class=\"media-credits\">Santa Casa de S\u00e3o Paulo Museum - Reproduction L\u00e9o Ramos Chaves\u2009\/\u2009Revista Pesquisa FAPESP<\/span><\/p><\/div>\n<p>Another unsuccessful experiment, in Paris, in 1678, led to France and England prohibiting \u2014 and criminalizing \u2014 blood transfusions. In Edinburgh, Scotland, in 1818, obstetrician James Blundell (1790-1878) turned things around when, after experimenting with animals, he performed the first successful transfusion for women with postpartum hemorrhaging. He used a funnel to hold the blood taken from the donor\u2019s vein, which flowed through a hose and entered the recipient through a needle. His technique was limited to extremely severe cases, when death was nearly certain, because the results were uncertain: some patients recovered, but others died.<\/p>\n<p>The risks dropped considerably as of 1901. In that year, while investigating the cause of death of patients after blood transfusions, Austrian pathologist Karl Landsteiner (1868-1943), of the Anatomical Pathology Institute of Vienna, then capital of the Austro-Hungarian Empire, identified the first blood group, the ABO system, consisting of four types (A, B, AB, and O), and characterized by the presence or absence of specific proteins in the red cells or blood plasma. It became clear that the unwanted reactions were the result of the recipient\u2019s defense system attacking the incompatible proteins from the donor. His work earned him the 1930 Nobel Prize in Physiology or Medicine.<\/p>\n<div id=\"attachment_540378\" style=\"max-width: 1150px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-540378 size-full\" src=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-transfusor-2024-07.jpg\" alt=\"\" width=\"1140\" height=\"635\" srcset=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-transfusor-2024-07.jpg 1140w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-transfusor-2024-07-250x139.jpg 250w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-transfusor-2024-07-700x390.jpg 700w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-transfusor-2024-07-120x67.jpg 120w\" sizes=\"auto, (max-width: 1140px) 100vw, 1140px\" \/><p class=\"wp-caption-text\"><span class=\"media-credits-inline\">Historical Museum of FM-USP - Reproduction L\u00e9o Ramos Chaves\u2009\/\u2009Revista Pesquisa FAPESP<\/span>A transfuser with rubber tubes, created by Brazilian physician Jos\u00e9 Augusto de Arruda Botelho to transfuse blood directly from the donor to the patient<span class=\"media-credits\">Historical Museum of FM-USP - Reproduction L\u00e9o Ramos Chaves\u2009\/\u2009Revista Pesquisa FAPESP<\/span><\/p><\/div>\n<p>In 1940, at the Rockefeller Institute for Medical Research, in New York, Landsteiner and North American physician Alexander Salomon Wiener (1907-1976) discovered the Rh factor, an antigen \u2014 protein capable of activating the body\u2019s defenses \u2014 in the serum of rabbits immunized with blood from a rhesus monkey.

The patient was 26-year-old domestic worker Maria Salustiana, who was suffering from severe anemia after hemorrhaging following surgery to remove a polyp from her cervix.<\/p>\n<p>Fr\u00f3es used a device designed by Agote. The donor\u2019s blood was stored with sodium citrate in a container attached to two hoses. A smaller bottle attached to one of the hoses contained a rubber pump that applied pressure so the blood would flow through the other hose to the needle and the patient\u2019s arm. The blood type, though already known, was not tested. Luckily, the blood from the donor \u2014 Jo\u00e3o Cassiano, a hospital orderly, chosen because he appeared to be in good health at the age of 22 \u2014 and Salustiana\u2019s blood were compatible.<\/p>\n<p>In 1916, doctor Isaura Leit\u00e3o de Carvalho (1885?-1928) described this and three other successful blood transfusions, also without mentioning blood typing, performed that very year by Fr\u00f3es, the advisor for her grad work presented at the Bahia School of Medicine at the Federal University of Bahia (UFBA). In 2019, hematologist Cristiane Silveira Cunha revisited the records of these stories in her dissertation, presented at the Federal University of the State of Rio de Janeiro (UNIRIO). \u201cI had to search quite a bit but I visited the outpatient clinic where Isaura worked and found a great-niece, Ana Mary, who kept photos of her,\u201d she recounts.<\/p>\n<p>Cunha also found an account of the indifference with which other physicians reacted to the presentation given by Fr\u00f3es on May 5, 1918, at Sociedade M\u00e9dica dos Hospitais da Bahia.

An evolution of Agote\u2019s device, the Jub\u00e9 syringe \u2014 created by French physician Louis Jub\u00e9 (1899-?) in 1924 \u2014 made the job easier by connecting the donor\u2019s arm to the recipient\u2019s arm with two hoses and dispensing with the use of an anticoagulant. Clamps on the hoses ensured that the blood would flow to the correct side. The circuit was vacuum-sealed and easy to sterilize. With access to blood typing reagents, doctors established transfusion services, with records of type O donors, who could donate to all other types. In reality, there was no such thing as donation, since all transfusions were paid for.<\/p>\n<div id=\"attachment_540354\" style=\"max-width: 810px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-540354 size-full\" src=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-cartaz-2024-07-800.jpg\" alt=\"\" width=\"800\" height=\"1276\" srcset=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-cartaz-2024-07-800.jpg 800w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-cartaz-2024-07-800-250x399.jpg 250w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-cartaz-2024-07-800-700x1117.jpg 700w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/01\/RPF-memoria-sangue-cartaz-2024-07-800-120x191.jpg 120w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><p class=\"wp-caption-text\"><span class=\"media-credits-inline\">Fiocruz<\/span>A poster for a blood donation campaign, inspired by the Henfil Law<span class=\"media-credits\">Fiocruz<\/span><\/p><\/div>\n<p>The Second World War (1939-1949) prompted the creation of blood banks around the world. In Brazil, the first was established in 1942 at the Fernandes Figueira Institute, in Rio de Janeiro. Simultaneously, hemotherapy became a medical field. Until then, transfusions were conducted by surgeons and obstetricians, while hematology dealt with infectious diseases, such as Chagas disease and yellow fever. Created in 1950, the Brazilian Society of Hematology and Hemotherapy (SBHH) united the two fields.<\/p>\n<p>\u201cUntil 1980, paid donations were a way of life. The poorest donated the most, in exchange for a few bucks,\u201d recounts hematologist Nelson Hamerschlak, of Hospital Israelita Albert Einstein. \u201cIt was concerning because the agents that caused hepatitis and Chagas disease could be transmitted by blood.\u201d To remedy the situation, in 1979, the SBHH launched a campaign for altruistic blood donation.<\/p>\n<p>On April 30 of the following year, the National Hemocomponents and Blood Program (Pr\u00f3-sangue) established the Brazilian hemotherapy system, with the creation of blood centers, specialized in collecting, processing, and storing blood and its components. One of its guidelines was that donation was unpaid; another was donor and recipient safety, which the HIV\/AIDS epidemic of the 1980s put to the test. \u201cThe number of cases where the HIV virus, which causes AIDS, was transmitted began to spike dramatically, particularly in patients with hemophilia or those who received several transfusions,\u201d recalls the University of Campinas (UNICAMP) hematologist Carmino Ant\u00f4nio de Souza (<a href=\"https:\/\/revistapesquisa.fapesp.br\/en\/carmino-antonio-de-souza-the-ways-of-healthcare\/\" target=\"_blank\" rel=\"noopener\"><em>see <\/em>Pesquisa FAPESP <em>issue n\u00ba 323<\/em><\/a>). \u201cUnfortunately, we had not established laboratory methods to prevent transmission or treat patients with completely safe products.\u201d<\/p>\n<p>In 1988, the Henfil Law \u2014 named after cartoonist Henrique de Souza Filho (1944-1988), who was a hemophiliac and, like his two brothers, contracted HIV from a transfusion \u2014 mandated serological tests to detect HIV That year, the Constitution gave the government the power to regulate, supervise, and control blood and its components, such as plasma, and banned its sale.<\/p>\n<p>It was only in 2014 that the Brazilian Health Regulatory Agency (ANVISA) published the requirements that must be met at any blood center in Brazil.
