|Transmission of hepatitis C virus (HCV) occurs primarily through blood-to-blood contact, with injecting drug use reported as the predominant risk factor for infection.1 Epidemiological studies have implicated tattooing as a risk factor for HCV infection.2-7 Possible transmission of hepatitis C virus by tattooing has rarely been reported in the literature,8-10 and none of the three previous reports has documented HCV seroconversion. HCV infection is highly prevalent in correctional facilities, and inmates commonly report behaviours associated with blood-to-blood contact.9,11,12 Despite high levels of HCV seroprevalence among prison inmates, reports of HCV transmission in the prison setting are uncommon.11,13,14 We report a well-defined case of acute HCV infection and subsequent viral clearance in a prisoner after tattooing.|
In April 1999, a 25-year-old man who had been continuously imprisoned
since 1997 presented with symptoms of jaundice, dark urine, malaise,
nausea, anorexia, sweats and headache. Liver function tests showed
biochemical hepatitis (see Figure), and he was hospitalised.
The patient had never been tattooed before entering prison, but was tattooed on four occasions inside prison (December 1997, September and December 1998, and early April 1999). The two most recent episodes were within the recognised incubation period for hepatitis C virus infection of 3-20 weeks.1 On both occasions fellow inmates tattooed him with sewing needles. The needle used for the December 1998 episode of tattooing was soaked in a 1% bleach solution for one hour, and then wiped and rinsed with water before use. The patient was unsure if the needle was used to tattoo another prisoner before him. He reported that the needle used in the most recent episode (in April 1999) had not been previously used for tattooing. He was unsure if the same stock of pigment had been used to tattoo another prisoner before him on either occasion.
The patient denied previous tattooing, injecting drug use, blood transfusion, needlestick injury and sharing of razors or toothbrushes and having sex while inside prison. He took no regular medications. In March 1998 he had been in a fight, in which he sustained lacerations to his lips and knuckles. He admitted to using drugs, including cocaine, marijuana and ecstasy, before his imprisonment, but only via non-injecting routes of administration. During imprisonment he admitted to smoking marijuana, and had lost visiting privileges when three random urine tests detected marijuana. His prison medical record had no reference to injecting drug use. Several healthcare workers, including a drug and alcohol counsellor, had interviewed him over a two-year period and all had recorded a similar history of non-injecting drug use only.
Physical examination five months after presentation, in November 1999, showed no stigmata of chronic liver disease, a normal liver span and no splenomegaly. There were three tattoos and no evidence of injection scars in the cubital fossae or elsewhere.
Testing showed seroconversion to HCV in samples collected longitudinally between 1997 and 1999 (see Figure). HCV viraemia was detected by polymerase chain reaction on two occasions in the acute phase of the illness. Serological testing for alternative causes of hepatitis showed no evidence of recent infection with hepatitis A, B or E, human immunodeficiency virus, syphilis or cytomegalovirus. Immunoglobulin G (IgG) antibodies against Epstein-Barr virus, human herpes virus type 6 and Toxoplasma gondii were detected at the first sampling point, indicating prior exposure. To corroborate the inmate's self-report and medical interviews, a 5 cm scalp hair sample was taken and tested for injectable drugs. The sample represented hair growth from July to November 1999, a period after the onset of hepatitis, during which the inmate had been prescribed a combination oral analgesic containing codeine. This sample was tested by gas chromatography and mass spectrometry for cocaine, amphetamines, methadone, codeine, morphine and 6-monoacetyl morphine (a heroin metabolite). The analysis showed the presence of codeine and morphine; a quantitative analysis was not possible.
This report describes a case of HCV transmission in prison in which
tattooing was the most likely route of transmission -- there were two
episodes of tattooing during the recognised incubation period of HCV
infection, with subsequent symptomatic hepatitis, seroconversion
Previous reports have not demonstrated seroconversion, leaving uncertainty as to the association between the tattooing, hepatitis and HCV infection.8-10 Nor have they attempted to exclude injecting drug use as a confounding risk for HCV acquisition. In this patient, the presence of morphine in the hair may relate to prescribed codeine analgesia or indicate undisclosed drug use in the period after the onset of the illness (the period represented by the hair sample). This was unable to be resolved with further interviews as the inmate was lost to follow-up. Thus, the possibility of undisclosed injecting drug use cannot be completely discounted as the route of transmission. It is very unlikely that the patient acquired HCV through blood-to-blood contact during the reported fight, as the clinical illness occurred more than one year after this event. Although tattooing represents a biologically plausible means for the transmission of HCV, this case illustrates that undisclosed injecting drug use may be a confounder in studies where tattooing is the only acknowledged risk factor for transmission of HCV. Indeed, in one study of recently released New South Wales prison inmates, injecting drug users were more likely to report receiving a tattoo in prison than non-injecting drug users.12
Previously reported modes of transmission of HCV in prisons include sharing drug injecting equipment, fights between inmates, barbers shears11 and a blood splash to the eye.14 Clinically apparent cases are likely to represent a small proportion of new HCV infections in prisons. Clinically apparent hepatitis is uncommon in primary HCV infection,1 occurring in only one case in every five.
Prison inmates report boredom as a common motivation for tattooing inside prison.15 As tattooing is likely to continue among prison inmates despite being banned, allowing access to licensed tattooists (or trained prisoners), with effective infection control procedures, may reduce the risk of HCV transmission in prisons.
In conclusion, large, prospective studies with meticulous assessment of confounding risk factors are required to effectively assess the potential association between tattooing and primary HCV infection.
