Tattooing and transfusion-transmitted diseases in Brazil: a hospital-based cross-sectional matched study

Increased prevalence of transfusion-transmitted diseases among people with tattoos: A systematic review and meta-analysis

Whether having a tattoo increases the risk of transfusion-transmitted diseases (TTDs) is controversial. Although a few studies have suggested a strong association between having tattoos and TTDs, other studies have not shown the significance of the association. In addition, previous studies mainly focused only on hepatitis C viral infections. The objective of our study was to identify the prevalence and risk of TTDs in people with tattoos as compared with the non-tattooed population. A systematic review of the studies published before January 22, 2021, was performed using the Pubmed, Embase, and Web of Science databases. Observational studies on hepatitis C virus (HCV), hepatitis B virus (HBV), human immunodeficiency virus (HIV), and syphilis infections in people with and without tattoos were included. Studies that reported disease status without serological confirmation were excluded. A total of 121 studies were quantitatively analyzed. HCV (odds ratio [OR], 2.37; 95% confidence interval [CI], 2.04–2.76), HBV (OR, 1.55; 95% CI, 1.31–1.83), and HIV infections (OR, 3.55; 95% CI, 2.34–5.39) were more prevalent in the tattooed population. In subgroup analyses, the prevalence of HCV infection was significantly elevated in the general population, hospital patient, blood donor, intravenous (IV) drug user, and prisoner groups. IV drug users and prisoners showed high prevalence rates of HBV infection. The prevalence of HIV infection was significantly increased in the general population and prisoner groups. Having a tattoo is associated with an increased prevalence of TTDs. Our approach clarifies in-depth and supports a guideline for TTD screening in the tattooed population.

Non-compliance to infectious disease deferral criteria among Hong Kong's blood donors

BACKGROUND AND OBJECTIVES

Donor screening alone cannot eliminate the risk of transfusion-transmitted HIV infection. Donor deferral according to established criteria is a supplemental strategy, which has focused largely on men who have sex with men (MSM). A study was conducted to determine the compliance of non-MSM donors with such criteria and examine its implications on blood safety.

MATERIALS AND METHODS

Chinese donors who have just donated blood at blood donor centres in Hong Kong were recruited. Based on the contents of the routinely administered predonation Health Screening Questionnaires, participants were requested to complete a survey to assess their practice of deferrable risk behaviours and lifestyle encounters, using tablet computers.

RESULTS

Over an 8-week period in mid-2016, 1614 donors (male-to-female ratio 1·23) had enrolled in the survey, accounting for 40% of donors giving blood on the survey days. The proportion of respondents who gave blood despite having deferrable HIV risk was 5%: MSM 1·2% (of the male donors); non-MSM risk behaviours 2·6%; risky lifestyle encounters 2·1%. If inconsistent declaration and suspected risk behaviours were included, the total non-compliance rate became 10·8%. Male donors had a higher prevalence of deferrable behavioural risk, even after excluding MSM. Unawareness and non-acceptability were main reasons for non-compliance.

CONCLUSION

The non-compliance rate of donors to deferral was high, although the ultimate infection risk might be small in the presence of universal screening. Simplification of questionnaires, focus on time-limited deferral and a reduction of deferral items may improve the deferral mechanism without compromising blood safety.

Risk factors for hepatitis C virus transmission in the municipality of Catanduva, State of São Paulo: a case-control study

INTRODUCTION

Hepatitis C virus (HCV) is primarily transmitted via contact with the blood of infected patients, although the form of contact has not been identified for a significant percentage of carriers. The present study evaluated possible risk factors for HCV transmission in a medium-sized town located in the northwest region of the State of São Paulo.

METHODS

This was a case-control study, with the case group consisting of 190 chronic HCV carriers older than 18 years residing in the municipality of Catanduva. The control group also consisted of 190 individuals with HCV-negative serology. The groups were paired (1:1) for gender, age range (± five years), and place of residence. The same structured questionnaire was applied to all subjects, who gave written informed consent to participate in the study. The data were statistically analyzed using crude and adjusted logistic regression, and the results were expressed as odds ratios with a 95% confidence interval.

RESULTS

The demographic profiles of the groups indicated a predominance of males (68.9%) and mean ages of 47.1 years (case group) and 47.3 years (control group). After adjusting for conditional regression, the following factors were found to represent risks for HCV: history of sexually transmitted disease (STD) and blood transfusion; accidents with syringes and/or needles; tattoos; and the use of non-injectable drugs and injectable medications.

CONCLUSIONS

The transmission of HCV via the blood route has been well characterized. Other forms of contact with human blood and/or secretions are likely to transmit the virus, although with a lower frequency of occurrence.

Infections associated with body modification

Although exact statistics are lacking, body modifications for cosmetic purposes are performed in many countries. The commonest forms include tattooing, body piercing, and breast and facial augmentation using implants or injectable fillers. Liposuction and, to a lesser extent, mesotherapy are also practiced in many countries. Infective complications of these procedures include local infections, transmission of bloodborne pathogens (viral hepatitis and human immunodeficiency virus), and distant infections such as infective endocarditis. Presence of foreign bodies, long healing time of piercing wounds, and poor compliance with infection control practices of some practitioners all predispose the recipients to infections. Apart from the endogenous microbial flora of the skin and mucosae, atypical mycobacteria, especially the rapid growers, have emerged as some of the most important pathogens in such settings. Outbreaks of infection are commonly reported. We hereby review the current knowledge of the topic with specific focus on infections associated with tattooing, body piercing, breast augmentation, mesotherapy, liposuction, and tissue filler injections. Greater awareness among consumers and health-care professionals, as well as more stringent regulations by the health authorities, is essential to minimize the health risks arising from these procedures.

Prevalence, distribution, and correlates of hepatitis C virus infection among homeless adults in Los Angeles

OBJECTIVE

We documented the prevalence, distribution, and correlates of hepatitis C virus (HCV) infection among urban homeless adults.

METHODS

We sampled a community-based probability sample of 534 homeless adults from 41 shelters and meal programs in the Skid Row area of downtown Los Angeles, California. Participants were interviewed and tested for HCV, hepatitis B, and HIV. Outcomes included prevalence, distribution, and correlates of HCV infection; awareness of HCV positivity; and HCV counseling and treatment history.

RESULTS

Overall, 26.7% of the sample tested HCV-positive and 4.0% tested HIV-positive. In logistic regression analysis, independent predictors of HCV infection for the total sample included older age, less education, prison history, and single- and multiple-drug injection. Among lifetime drug injectors, independent predictors of HCV infection included older age, prison history, and no history of intranasal cocaine use. Among reported non-injectors, predictors of HCV infection included older age, less education, use of non-injection drugs, and three or more tattoos. Sexual behaviors and snorting or smoking drugs had no independent relationship with HCV infection. Among HCV-infected adults, nearly half (46.1%) were unaware of their infection.

CONCLUSIONS

Despite the high prevalence of HCV infection, nearly half of the cases were hidden and few had ever received any HCV-related treatment. While injection drug use was the strongest independent predictor, patterns of injection drug use, non-injection drug use, prison stays, and multiple tattoos were also independent predictors of HCV. Findings suggest that urgent interventions are needed to screen, counsel, and treat urban homeless adults for HCV infection.

Transmission of hepatitis C virus infection through tattooing and piercing: a critical review

Tattoos and piercings are increasing, especially among youths, but the risk of hepatitis C virus (HCV) infection from these practices has not been adequately assessed and there are conflicting findings in the literature. We evaluated the risk of HCV infection from tattooing and piercing using the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. Studies that specified the venue of tattooing and/or piercing showed no definitive evidence for an increased risk of HCV infection when tattoos and piercings were received in professional parlors. However, the risk of HCV infection is significant, especially among high-risk groups (adjusted odds ratio, 2.0-3.6), when tattoos are applied in prison settings or by friends. Prevention interventions are needed to avoid the transmission of hepatitis C from tattooing and piercing in prisons, homes, and other potentially nonsterile settings. Youths also should be educated on the need to have tattoos and piercings performed under sterile conditions to avoid HCV infection.

People with multiple tattoos and/or piercings are not at increased risk for HBV or HCV in The Netherlands

Background

Although published results are inconsistent, it has been suggested that tattooing and piercing are risk factors for HBV and HCV infections. To examine whether tattooing and piercing do indeed increase the risk of infection, we conducted a study among people with multiple tattoos and/or piercings in the Netherlands who acquired their tattoos and piercings in the Netherlands and/or abroad.

Methods

Tattoo artists, piercers, and people with multiple tattoos and/or piercings were recruited at tattoo conventions, shops (N = 182), and a biannual survey at our STI-outpatient clinic (N = 252) in Amsterdam. Participants were interviewed and tested for anti-HBc and anti-HCV. Determinants of HBV and HCV infections were analysed using logistic regression analysis.

Results

The median number of tattoos and piercings was 5 (IQR 2–10) and 2 (IQR 2–4), respectively. Almost 40% acquired their tattoo of piercing abroad. In total, 18/434 (4.2%, 95%CI: 2.64%–6.46%) participants were anti-HBc positive and 1 was anti-HCV positive (0.2%, 95%CI: 0.01%–1.29%). Being anti-HBc positive was independently associated with older age (OR 1.68, 95%CI: 1.03–2.75 per 10 years older) and being born in an HBV-endemic country (OR 7.39, 95%CI: 2.77–19.7). Tattoo- and/or piercing-related variables, like having a tattoo or piercing in an HBV endemic country, surface percentage tattooed, number of tattoos and piercings etc., were not associated with either HBV or HCV.

Conclusions

We found no evidence for an increased HBV/HCV seroprevalence among persons with multiple tattoos and/or piercings, which might be due to the introduction of hygiene guidelines for tattoo and piercing shops in combination with the low observed prevalence of HBV/HCV in the general population. Tattoos and/or piercings, therefore, should not be considered risk factors for HBV/HCV in the Dutch population. These findings imply the importance of implementation of hygiene guidelines in other countries.

Hepatitis B virus and hepatitis C virus infections among female sex workers and men who have sex with men in Lebanon: prevalence, risk behaviour and immune status

BACKGROUND

The aim of our study was to study the prevalence of and the risk behaviours associated with the hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among two high-risk groups: female sex workers (FSW) and men who have sex with men (MSM). Furthermore, since vaccination is a key component of HBV prevention programs, the immune status of HBV infection in these two high-risk groups was evaluated.

METHODS

Participants included in this study were part of a bio-behavioural surveillance study done to assess HIV prevalence among four vulnerable groups in Lebanon. Participants were recruited using a respondent-driven sampling method. The total number of eligible participants were 101 MSM and 103 FSW. Blood samples were collected as dried blood spots and then eluted to be tested for HCV, HBV and HIV by enzyme-linked immunosorbent assay.

RESULTS

None of the 204 individuals tested has been exposed to HCV. In the 101 MSM, only one (0.99%) was an HBsAg carrier and one (0.99%) was confirmed as anti-HIV-positive. Among FSW, 30% showed they were immune to HBV compared with only ~10% among MSM. The distribution of socio-demographic characteristics and potential risk factors in both groups were shown.

CONCLUSION

Our results highlight the urgent need to raise awareness among FSW and MSM and their health care providers of the availability and benefits of HBV vaccination in Lebanon. In addition, and due to the absence of vaccines against HCV and HIV, education programs aiming at behavioural changes should be intensified.

Hepatitis C and HIV coinfection in central region of Argentina: prevalence, genotype characterization and risk factors

BACKGROUND

This is the first study reporting the epidemiological and molecular characterization of HCV/HIV coinfection in the central region of Argentina.

METHOD

Cross-sectional, epidemiological study (2003-2004).

STATISTICS

multivariate logistic regression analysis.

RESULTS

The incidence of HCV/HIV coinfection was 12.3%. HCV genotype 1 was the most prevalent (73%). Intravenous drug use was the main independent risk factor for acquiring HCV infection. However, an alternative route (sexual) for viral transmission was suggested.

CONCLUSIONS

These results underscore the potential public health impact of HCV/HIV coinfection in our region.

Avoidance of tattoo disruption: a further benefit of laparoscopic surgery

INTRODUCTION

Tattoos are increasingly common in both male and female patients. Abdominal skin tattoos may be present at the site of proposed incisions for conventional surgery whereas laparoscopic port site placement can be adjusted to accommodate tattoo constraints.

METHODS

Patients with tattoos were questioned by face-to-face interview to determine how long ago they had their tattoo, financial cost of the tattoo, and potential degree of distress caused by disruption of their tattoo (on a scale of 1-10). Consultant and higher surgical trainee general surgeons were asked by e-mail survey whether they had encountered a patient with a tattoo at the site of a proposed incision, did they avoid incising the tattoo during surgical intervention, and had they received a complaint from a patient about tattoo distortion.

RESULTS

Ninety six patients (50 male, median age 29 years) were questioned. Median cost of the tattoos was pound35 ($70). Female patients were more likely to be distressed and complain than men about tattoo disruption (p = 0.0003) and there was a significant inverse correlation between time from tattooing and distress (p = 0.02). Most (79%) of the general surgeons questioned (n = 107, response rate 82%) had encountered tattoos at proposed incision sites; 61% had avoided making an incision through it and 4% had received a complaint about tattoo disruption by a patient.

CONCLUSION

Tattoo disruption by surgical incision may cause distress especially in female patients who had their tattoo recently. Tattoos should be avoided where possible by alternative port site placement.

Fever of unknown origin due to zoonoses

Fevers of unknown origin have been classified as classic, nosocomial, immune-deficient, and HIV-related. More than half of the 1407 human pathogens are zoonotic, making zoonotic infections an important subcategory in each of the classifications. This article describes both common and unusual zoonoses causing fevers of unknown origin. Simian immune virus is considered as a possible emerging infection. For special populations (the homeless, zoophiliacs, those whose occupation or leisure brings them in close contact with oceans or lakes, and veterinarians), zoonotic infection potentials are discussed.

Body of evidence: tattoos, body piercing, and eating disorder symptoms among adolescents

OBJECTIVE

Tattoos and body piercing have been linked to risk-taking behaviors, including disordered eating, but the findings have come from selected samples that were at greater risk for bias due to comorbidity. This study set out to explore concurrently the prevalence of tattoos and body piercing, and eating disorder symptoms in a representative adolescent sample of a community in Sardinia, a major island in Italy.

METHODS

A community sample of 828 students (female, 535; male, 282; mean age=17.5+/-1.4 years) among those attending high school in the district of Cagliari, Italy, were invited to take the Eating Attitudes Test, the Bulimic Investigatory Test of Edinburgh, and the Body Attitudes Test, alongside a short questionnaire aimed at evaluating their resorting to body modification practices, including tattooing and body piercing.

RESULTS

Females scored higher than males at all eating disorder inventories. More males than females admitted the use of tattoos (14.5% vs. 5.4%), whereas the reverse was found for body piercing (18.4% vs. 21.3%). Tattoos among females and body piercing in both genders were statistically associated with eating disorder measures related to bulimia symptoms. On the whole, the degree of association was modest.

CONCLUSIONS

Tattoos and body piecing should be seen as desires to show a subject's identity rather than as a marker of psychopathology. Greater health education, however, is needed in the wake of the growing popularity of these body modification practices.

Tattoos and body piercings in the United States: a national data set

BACKGROUND

Little is known about the prevalence and consequences of body art application.

OBJECTIVE

Our aim was to provide US tattooing and body piercing prevalence, societal distribution, and medical and social consequence data.

METHODS

Random digit dialing technology was used to obtain a national probability sample of 253 women and 247 men who were 18 to 50 years of age.

RESULTS

Of our respondents, 24% had tattoos and 14% had body piercings. Tattooing was equally common in both sexes, but body piercing was more common among women. Other associations were a lack of religious affiliation, extended jail time, previous drinking, and recreational drug use. Local medical complications, including broken teeth, were present in one third of those with body piercings. The prevalence of jewelry allergy increased with the number of piercings. Of those with tattoos, 17% were considering removal but none had had a tattoo removed.

LIMITATIONS

This was a self-reported data set with a 33% response rate.

CONCLUSION

Tattooing and body piercing are associated with risk-taking activities. Body piercing has a high incidence of medical complications.

Prevalence of selected viral infections among temporarily deferred donors who returned to donate blood: American Red Cross blood donor study

BACKGROUND

Health history questions are introduced into the predonation interview to identify blood donors believed to pose a higher risk of infectious diseases to recipients. This study assesses the current impact of some of those questions.

STUDY DESIGN AND METHODS

Donor deferral and donation data were extracted from a research database of the American Red Cross. The prevalence of hepatitis B surface antigen or antibodies to human immunodeficiency virus, hepatitis C virus, or human T-lymphotropic virus was obtained for different groups of donors who were temporarily deferred in 2000 through 2001 and later returned to donate blood in 2000 through 2003. The results were compared with either first-time or repeat donors in 2000 through 2003, while controlling for differences in sex, age, and year of donation.

RESULTS

Of donors temporarily deferred in 2000 through 2001 who had had no donation or deferral during the previous 2 years, only 22.08 percent subsequently returned to donate blood in 2000 through 2003. Donations from returning donors who had been deferred for potential infectious disease risk did not show a higher prevalence for any of the viral markers when those with no donation or deferral during the previous two years were compared with first-time donations, and those with prior donation were compared with repeat donations.

CONCLUSION

Blood donors temporarily deferred in 2000 through 2001 for potential risk of viral infection who later returned to donate blood did not appear to pose a higher risk compared to first-time or repeat donors. The effectiveness of some of the currently used deferral questions in reducing viral risks warrants further study.
