Hong Kong ( CNN ) -- One of four Hong Kong women struck down with septic shock after receiving a `` beauty '' treatment normally given to cancer patients has died . The 46-year-old died Wednesday morning at a local hospital one week after receiving DC-CIK therapy through the DR beauty center , local authorities said . According to the Hong Kong Health Department , the DC-CIK procedure involves the `` concentration and processing of blood taken from the person , and subsequent infusion of the mixture back into the patient . '' It 's not clear whether any of the women who received the treatment had been diagnosed with cancer , though the Hong Kong Health Department said in an earlier statement that the 46-year-old had been in `` good past health . '' The woman , who has only been identified by authorities by her surname `` Chan , '' was admitted to hospital last Thursday suffering fever and diarrhea , hours after receiving the treatment . She was diagnosed with septic shock , and on Sunday authorities announced her blood samples had grown the bacterium Mycobacterium abscessus . Dr. Ho Pak-leung , President of the University of Hong Kong 's Center for Infection told CNN that , under normal circumstances , M. abscessus did not pose a threat to healthy people . `` It 's common , it 's widespread . It can be found in dust and soil and water . People often come into contact with a small number of this bacteria and it 's of no harm at all unless you have a wound , '' Dr. Ho said . However , he said it appeared as though the bacteria had entered the woman 's blood . `` For blood infection involving internal organs , it 's very difficult . It has to involve multiple drugs given at the same time and there are uncertainties about the effectiveness of the treatment , '' he told CNN on Monday . Three other women remain in hospital after having the treatment , health authorities said Wednesday . A 60-year-old is in critical condition , a 56-year-old woman is in serious condition , while another , 59 , is stable . Dr. Ho said the use of the DC-CIK treatment for cosmetic purposes was not something he 'd ever heard of before . `` I have serious doubts about the medical and scientific basis of the treatment , '' he said . Professor KY Yuen , Chair of Infectious Diseases at the University of Hong Kong 's Department of Microbiology , said the procedure was `` only indicated for patients with metastatic cancer and often as salvage therapy when there are no other feasible options . '' The Hong Kong Health Department and police are investigating the matter but , as of Wednesday morning , police said no arrests had been made . Health authorities have instructed the DR beauty clinic to halt the procedure . Over the weekend , the founder of DR , Dr. Stephen Chow Heung-wing , told local media that his staff referred clients to an independent doctor who administered the therapy . He denied suggestions that it was offered as a medical treatment . The clinic has yet to respond to CNN requests for reaction to Wednesday 's death . `` I did n't say that it can cure any diseases . Remember that we are a beauty clinic . We refer clients to doctor ( s ) , and we have had the clients to sign a liability-free form , which states that it is not for medical use , '' he said . A statement on the beauty clinic 's website says that the treatment `` was conducted by an independent doctor at a medical clinic , and the doctor is not hired by our beauty store . '' The statement also said it was up to the independent doctor to decide whether the client is suitable for treatment before he or she receives it . It added : `` We will assist related government departments to find out the causation of this particular incident . '' According to its website , the DR group of clinics was established in 1995 and provides services for more than 1,000 clients each day . The 'Wild West ' of medicine .
