Depression, Anxiety, and Stress Among People With Chronic Hepatitis C Virus Infection and a History of Injecting Drug Use in New South Wales, Australia

Diagnostic Overshadowing of Chronic Hepatitis C in People With Mental Health Conditions Who Inject Drugs: A Scoping Review

Diagnostic overshadowing refers to a phenomenon whereby people with mental health conditions encounter inadequate or delayed medical attention and misdiagnosis. This occurs when physical symptoms are mistakenly attributed to their mental health condition. This paper presents a scoping review focusing on direct causes and background factors of diagnostic overshadowing in the context of hepatitis C infection in people who inject drugs and have concurrent mental health conditions. Despite significant strides in hepatitis C treatment with direct-acting antiviral drugs, the complex interplay of mental health conditions and physical symptoms necessitates a nuanced approach for accurate diagnosis and effective screening. This review was conducted using Joanna Briggs Institute's methodology for scoping reviews. The databases searched included Medline, Embase, PsycInfo, Global Health, CINAHL and Scopus. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The search strategies identified 1995 records. Overall, 166 studies were excluded. Forty-two (42) studies met the inclusion criteria. Three (n = 3) studies represented direct causes, and 39 (n = 39) with background factors related to diagnostic overshadowing. Studies highlighted six key themes encompassing diagnostic overshadowing, with communication barriers, stigma and knowledge deficiencies being the most prominent. Recognising and addressing diagnostic overshadowing in chronic hepatitis C will lead to increased screening, diagnosis and timely administration of life-saving antiviral therapy, resulting in profound enhancements in well-being and health outcomes. Moreover, this proactive approach will play a pivotal role in advancing the global effort towards eliminating hepatitis C by 2030.

Reduction in Depressive Symptoms in People who Inject Drugs who Are Cured of Hepatitis C Virus Infection: The HERO Study

Background

Depressive symptoms are prevalent among people who inject drugs (PWID) and people with hepatitis C virus (HCV). We examined changes in depressive symptoms among HCV-infected PWID following direct-acting antiviral treatments to evaluate whether these changes differed by history of depressive symptoms, substance use, or HCV treatment outcome.

Methods

We conducted a secondary analysis of the HERO Study (NCT02824640), a pragmatic randomized clinical trial among PWID, to test the effectiveness of HCV care models. Depressive symptoms (primary outcome) were measured using the Patient Health Questionnaire (PHQ-9) at baseline, end of treatment (EOT), and at follow-up 12 and 24 weeks after EOT. Sustained virologic response (SVR) was defined as undetectable HCV RNA at ≥12 weeks following EOT. Baseline drug use was defined as having a positive urine screening test for amphetamine, methamphetamine, benzodiazepine, cocaine, cannabis, opiate, or oxycodone.

Results

The sample (n = 498) was 72.3% male, 64.2% White, and on average 43.9 years old. In patients who achieved SVR (F(3432) = 4.58; P = .004) and those with drug use at baseline (F(3478) = 5.11; P < .01), PHQ-9 scores significantly declined over time, with scores lower at EOT and both follow-ups as compared with baseline. Mean PHQ-9 scores at EOT and follow-ups were significantly lower than at baseline, except for those with no depression or mild depression at baseline.

Conclusions

This study showed that HCV treatment in PWID is associated with sustained declines in depression up to 24 weeks post-treatment among those who achieve SVR and that drug use does not interfere with improvement in depressive symptoms.

Community screening identifies undiagnosed chronic liver disease in high-risk populations

BACKGROUND AND AIM

Liver cirrhosis is the primary risk factor for the development of hepatocellular carcinoma. Most conditions that lead to cirrhosis are treatable, or modifiable. Therefore, a community-based screening program targeting high-risk groups was designed for early diagnosis and intervention of liver disease, to offset the rising burden of hepatocellular carcinoma in Australia.

METHODS

Two nurse consultants from a tertiary liver center performed community screening of pre-identified cohorts at risk of viral hepatitis and chronic liver disease, with transient elastography and/or serology testing for chronic hepatitis B virus (HBV) and hepatitis C virus (HCV), in addition to standard blood tests. A positive screening result was defined as any of the following: liver stiffness measurement (LSM) ≥ 9.5 kPa, positive HCV RNA, or positive HBV surface antigen. Individuals who screened positive were linked to the liver center for management.

RESULTS

Nine hundred and twenty-six subjects were screened over a 6-year period, of which 122/926 (13.2%) had evidence of chronic liver disease. Chronic viral hepatitis was diagnosed in 91 participants (HBV = 23, HCV = 67, and co-infection = 1), while non-alcoholic fatty liver disease was diagnosed in 14 participants. Advanced fibrosis (LSM ≥ 9.5 kPa) was detected in 42/866 (4.9%) subjects with available LSM. Loss to follow-up occurred in 36/91 (39.6%) participants with chronic viral hepatitis.

CONCLUSIONS

Targeting high-risk populations for community screening and intervention increases early identification of chronic liver disease. This may reduce the incidence of liver cirrhosis and hepatocellular carcinoma. Loss to follow-up remains an ongoing challenge, requiring better strategies.

Declines in Depressive Symptoms Among People who Inject Drugs Treated With Direct-Acting Antivirals While on Opioid Agonist Therapy

Background

Hepatitis C virus (HCV) frequently co-occurs with symptoms of depression, which are aggravated on interferon-based regimens. However, it is unknown whether HCV treatment with direct-acting antivirals (DAAs) has effects on depressive symptoms among people who inject drugs (PWID). In this study, we examined changes in depressive symptoms during and after HCV treatment among PWID on opioid agonist therapies (OATs).

Methods

Participants were 141 PWID who achieved sustained viral response after on-site HCV treatment at 3 OAT programs.

Depressive symptoms were assessed using the Beck Depression Inventory–II (BDI-II) at baseline, every 4 weeks during treatment, and 12 and 24 weeks after treatment completion. Current diagnosis of depression or other psychiatric diagnoses were obtained through chart review. Use of illicit drugs was measured by urine toxicology screening. Alcohol use was measured using the Addiction Severity Index–Lite.

Results

Of the 141 PWID infected with HCV, 24.1% had severe, 9.9% had moderate, 15.6% had mild, and 50.4% had minimal levels of depression as per BDI-II scores at baseline. HCV treatment was significantly associated with reductions in depressive symptoms that persisted long term, regardless of symptom severity (P < .001) or presence of depression (P ≤ .01) or other psychiatric diagnoses (P ≤ .01) at baseline. Concurrent drug use (P ≤ .001) or hazardous alcohol drinking (P ≤ .001) did not interfere with reductions in depressive symptoms.

Conclusions

Depressive symptoms are highly prevalent among HCV-infected PWID. HCV treatment was associated with sustained reductions in depressive symptoms. HCV therapy with DAAs may have important implications for PWID that go beyond HCV cure.

Associations between housing stability and injecting frequency fluctuations: findings from a cohort of people who inject drugs in Montréal, Canada

BACKGROUND

The relationship between housing stability and drug injecting is complex, as both outcomes fluctuate over time. The objectives were to identify short-term trajectories of housing stability and injecting frequency among people who inject drugs (PWID) and examine how patterns of injecting frequency relate to those of housing stability.

METHODS

At three-month intervals, PWID enrolled between 2011 and 2016 in the Hepatitis Cohort completed an interviewer-administered questionnaire and were tested for hepatitis C and HIV infections. At each visit, participants reported, for each of the past three months, the accommodation they lived in the longest (stable/unstable) and the number of injecting days (0-30). Group-based dual trajectory modeling was conducted to identify housing stability and injecting frequency trajectories evolving concomitantly over 12 months and estimate the probabilities of following injecting trajectories conditional upon housing trajectories.

RESULTS

386 participants were included (mean age 40.0, 82 % male). Three housing stability trajectories were identified: sustained (53 %), declining (20 %), and improving (27 %). Five injecting frequency trajectories were identified: sporadic (26 %), infrequent (34 %), increasing (15 %), decreasing (11 %), and frequent (13 %). PWID with improving housing were less likely to increase injecting (8 %) compared to those with sustained (17 %) or declining housing (17 %).

CONCLUSIONS

Improving housing was associated with a lower probability of increasing injecting compared to declining housing, while sustained housing stability was associated with a higher probability of increasing injecting compared to improving housing. Therefore, policies to improve PWID's access to stable housing are warranted and may reduce, to some extent, drug injecting and related harms.

Territory-wide population-based study of chronic hepatitis C infection and implications for hepatitis elimination in Hong Kong

BACKGROUND

To study the epidemiology of chronic hepatitis C virus infection in Hong Kong and to estimate the service gap for achieving the WHO hepatitis elimination targets of attaining a diagnosis rate of 90%, treatment rate of 80% and 65% reduction in mortality rate by 2030.

METHODS

From January 2005 to March 2017, patients who were tested positive for anti-HCV were retrospectively retrieved from all public hospitals in Hong Kong. The epidemiological data of 15 participating hospitals were analysed.

RESULTS

A total of 11 309 anti-HCV+ patients were identified and the estimated diagnosis rate was 50.9%. Our HCV-infected patients were ageing (median age 59). The all-cause mortality rate increased from 26.2 to 54.8 per 1000 person-years over the last decade. Our estimated treatment rate was 12.4%. Among the treated patients, 93.6% had received pegylated interferon/ribavirin (Peg-IFN/RBV) but only 10.8% had received interferon-free direct-acting antivirals (DAAs). In a cohort of 1533 patients, 39% already had advanced liver fibrosis or cirrhosis. The sustained virological response rate for Peg-IFN/RBV and DAAs were 74.8% and 97.2% respectively. However, more than 70% of patients were not subjected to interferon treatment for various reasons. Patients who achieved SVR were associated with a significantly lower risk of HCC (4.7% vs 9.6%, P = 0.005) and death (1.7% vs 23.8%, P < 0.001).

CONCLUSION

Our diagnosis rate, treatment rate and mortality rate reduction were still low, particularly the Peg-IFN outcomes, making it difficult to meet the WHO hepatitis elimination targets. A more generalized use of DAAs is urgently needed to improve the situation.

Direct-acting antiviral treatment of chronic HCV-infected patients on opioid substitution therapy: Still a concern in clinical practice?

BACKGROUND AND AIMS

There is limited real-world information on the effectiveness of antiviral treatment of chronic hepatitis C virus (HCV) infection with direct-acting antivirals (DAA) in people on opioid substitution therapy (OST). This study compared sustained virological response (SVR) rates and proportion of lost to follow-up (LTFU) between OST and non-OST patients in the German Hepatitis C-Registry (DHC-R).

DESIGN

National multi-centre prospective real-world registry (German Hepatitis C-Registry, DHC-R). Non-OST patients comprised patients with former/current drug use (non-OST/DU) and patients never consuming drugs (non-OST/NDU).

SETTING

A total of 254 medical centres in Germany, including 123 centres providing OST.

PARTICIPANTS

A total of 7747 chronic HCV patients started DAA therapy (739 OST and 7008 non-OST; 1500 non-OST/DU; 5508 non-OST/NDU) patients. Five hundred and twenty-eight OST and 5582 non-OST patients had completed antiviral therapy and at least one follow-up documentation [intention-to-treat (ITT) population].

MEASUREMENTS

Study outcomes were SVR, proportion of LTFU and safety of treatment.

FINDINGS

SVR (ITT) was documented in 85% (450 of 528) OST patients versus 86% (969 of 1126) in non-OST/DU (P = 0.651) and 92% (4113 of 4456) non-OST/NDU (P < 0.001) patients. Independent predictors for SVR (P < 0.01 in multivariate analysis) included HCV genotype non-3 [adjusted odds ratio (aOR) = 1.11; 95% confidence interval (CI) = 1.07-1.15], female sex (aOR = 1.59; CI = 1.30-1.94), platelet counts >90 × 109/l (aOR = 1.51, CI = 1.14-2.01), cirrhosis (aOR = 0.77; CI = 0.62-0.96) and patient group (OST/DI (aOR = 0.58; CI = 0.42-0.78); non-OST/DU (OR: 0.63; CI = 0.50-0.78). In per-protocol analysis (PP), SVR rates were ≥ 94% in all patient groups. In OST the proportion of LTFU was higher (10.2%) than in non-OST/DU (8.5%) and non-OST/NDU (3.2%, P < 0.001) patients. Independent factors for LTFU (P < 0.01) were HCV genotype non-3 (aOR = 0.92; CI = 0.88-0.96), female sex (aOR: 0.7; CI = 0.53-0.92), pre-treatment (aOR = 0.64; CI = 0.50-0.82), OST/DI (aOR = 3.35; CI = 2.35-4.78) and non-OST/DU (aOR = 2.38; CI = 1.80-3.14).

CONCLUSIONS

In Germany, direct-acting antiviral treatment of former or current drug users with or without opioid substitution therapy can achieve equally high sustained virological response rates as in patients with no history of drug use.

Mental health of heroin users with differing injection drug use histories: A non-treatment sample of Mexican American young adult men

BACKGROUND

While the comorbidity of mental health and injecting heroin has been documented, current research is limited by describing the mental health of people who inject drugs without a comparison group and by the lack of research on nontreatment samples in the United States, particularly among Hispanics. The purpose of this study was to examine the association of injecting history (never, former, occasional, and daily) and multiple outcomes of global and mental health using a sample of U.S.-based Latinos not currently in treatment.

METHODS

Data are from a sample of street-recruited Mexican American young adult men (n=275) in San Antonio, TX. Multiple logistic regression and structural equation modeling were used.

RESULTS

Overall 54% of men reported lifetime injecting drug use (20.7% former users, 11.1% occasional users, and 21.9% daily users). We found varying prevalence rates of global and mental health status among different histories of injecting. After covariate adjustment, daily injecting remained strongly associated with all four outcomes: perceived poor health status (AOR=4.39; p≤0.001), psychological distress (AOR=2.78; p≤0.05), depression (AOR=4.37; p≤0.001), and suicidal ideation (OR=4.75; p≤0.001). Acculturation, gang membership, and incarceration history also emerged as important factors.

CONCLUSION

This study provides new information about the relationship between mental health and injecting heroin use.

FINDINGS

Support the need to consider mental health states among people who inject drugs, and to examine varying histories of injecting with socially and culturally relevant factors.
