Effect of integrating HIV and addiction care for non-engaging HIV-infected opiate-dependent patients.

BACKGROUND: HIV-positive substance dependent patients contribute disproportionally to HIV morbidity and mortality as a result of poor compliance with their HIV treatment. For HIV-positive opiate-dependent patients integrating HIV and addiction care improves HIV morbidity but the effect on addiction morbidity is not known. AIMS: This study aims to establish if integrating HIV and addiction care has a significant effect on addiction and HIV morbidity for non-engaging HIV-positive opiate-dependent patients. METHODS: Patients attending the National Drug Treatment Centre who had disengaged from their HIV treatment in St James's Hospital were recruited to receive HIV care integrated into their methadone maintenance programme. Outcome was investigated in terms of urine toxicology (opiates, cocaine, cannabis and amphetamines); adherence to methadone; proportion receiving directly observed antiretroviral therapy; proportion HIV virally suppressed; and the CD4 cell count. RESULTS: No significant change in substance use or methadone adherence was demonstrated in the 19 recruited participants. There was a significant increase in the proportion receiving directly observed antiretroviral therapy, and in the CD4 cell count. CONCLUSION: Integration of HIV and addiction care optimises the physical health of non-engaging HIV-positive opiate-dependent patients with no substantial effect on their methadone maintenance programme.

Clinical and epidemiological characteristics of patients with early syphilis from three academic centres in Poland, Germany and Ireland: initial findings from the POETS study.

OBJECTIVES: Syphilis recognition in HIV-positive patients has important implications. Initial data from this study, established in June 2012 to better understand the natural history of syphilis and treatment response, examine the characteristics of patients including sexual behaviour, rates of concurrent sexually transmitted infections (STI) and type of treatment given. METHODS: Patients were recruited from Ireland, Poland and Germany. Data gathered included demographics, method of syphilis acquisition, stage of syphilis infection, HIV status, nadir and current CD4 counts and HIV viral suppression rates. Data were then subanalysed into HIV-positive and HIV-negative groups. RESULTS: Of 175 patients recruited, 68% were HIV-positive and 86.3% were men who have sex with men. Most HIV-positive patients presented with secondary syphilis (55.7% vs 13.2%) (p=0.0001) while the majority of HIV-negative patients had primary syphilis noted at the time of recruitment (47.2% vs18.9%, p=0.0002). Approximately half of all patients had a HIV RNA viral load <40 copies/mL (55%). Previous syphilis infection occurred more frequently in HIV-positive than HIV-negative patients (p=0.0001). Concurrent STIs at the time of syphilis diagnosis were found in 26.8%, of whom 31 (25.4%) were HIV-positive (p=0.64). HIV-positive patients received doxycycline more frequently than their HIV-negative counterparts (33.6% vs 1.9%, p=0.0001) while HIV-negative patients were treated with long-acting penicillin in 88.7% of cases vs 58% of HIV-positive patients (p=0.0002). CONCLUSIONS: A 40% rate of unsuppressed viraemia, high levels of STIs and varying treatment regimens represent a public health risk for Europe, suggesting the model of sexual healthcare delivery in HIV-positive patients requires further evaluation.

Prevalence of human papillomavirus in men who have sex with men in the era of an effective vaccine; a call to act.

OBJECTIVES: The incidence of human papillomavirus (HPV)-associated anal cancer is increasing. Men who have sex with men (MSM), particularly those coinfected with HIV, are disproportionately affected. Documenting the molecular epidemiology of HPV infection is important in guiding policy makers in formulating universal and/or targeted vaccine guidelines. METHODS: A prospective cohort study was conducted. HIV-positive and HIV-negative MSM > 18 years old were invited to participate. Provider-performed anal swabs were collected and anal HPV infection was detected using consensus primer solution phase polymerase chain reaction (PCR) followed by type-specific PCR for high-risk (HR)-HPV types 16, 18 and 31. Between-group differences were analysed using χ(2) tests and Wilcoxon rank tests. RESULTS: One hundred and ninety-four MSM [mean (standard deviation (SD)) age 36 (10) years; 51% HIV-positive) were recruited. The median number of sexual contacts in the preceding 12 months was 4 (interquartile range 2-10). HIV-positive subjects had a mean (SD) CD4 count of 557 (217) cells/µL, and 84% were on highly active antiretroviral therapy (HAART). Thirty-one samples were B-globin negative and thus excluded from further analysis. A total of 113 subjects (69%) had detectable HPV DNA. Sixty-eight subjects (42%) had an HR-HPV type detected. HR HPV type 16 was detected in 44 samples (27%), HR-HPV type 18 in 26 samples (16%) and HR-HPV type 31 in 14 samples (23%). Twenty-eight subjects (17%) had more than one type of HR-HPV type detected. When HPV and HR-HPV were stratified by age, those > 35 years had a higher prevalence (P = 0.001 and P = 0.028, respectively). HIV-positive subjects were more likely than HIV-negative subjects to have any detectable HPV (77% vs. 61%, respectively; P = 0.04), to have HR-HPV type 18 or 31 (P = 0.05 and P = 0.006, respectively) and to be infected with more than one HR-HPV type (31% vs. 3%, respectively; P < 0.001). Within the HIV-positive group, the prevalence of HPV was higher in those not on HAART (P = 0.041), although it did not differ when stratified by CD4 count. CONCLUSIONS: The identified prevalence of anal HPV infection was high. Emerging patterns of HPV-related disease strengthen the call for universal vaccination of boys and girls with consideration of catch-up and targeted vaccination of high-risk groups such as MSM and those with HIV infection.

Health-related quality of life of HIV-infected intravenous drug users.

To investigate health-related quality of life in HIV-infected intravenous drug users registered but not engaged in HIV outpatient care (missing ≥2 outpatient appointments over 1 year or non-attendance for ≥6 months) we conducted a cross-sectional study to examine health-related quality of life of HIV-infected intravenous drug users registered for care at an inner city HIV unit. EQ-5D, SF-36, SF-6D, mood disorder, clinical and substance misuse data were collected. Mean scores and preference derived utility scores were calculated. Statistical relationships between health-related quality of life and other variables were explored using univariate and multivariate analysis. Fifty-five patients were recruited, 64% were males. The mean anxiety value was 11.44 (anxious) and mean depression score was 9.3 (borderline depressed). The mean EQ-5D utility was 0.45 (95% CI 0.35, 0.55) and mean SF-6D utility was 0.52 (95% CI 0.48, 0.55). There was no statistical relationship between HIV indices, substance misuse and EQ-5D and SF-6D utility. Anxiety and depression were significantly correlated with EQ-5D and SF-6D utility values on univariate and multivariate analysis. Health-related quality of life was reduced in this HIV-infected intravenous drug user population. Whilst hepatitis C co-infection and substance misuse did not affect health-related quality of life, anxiety and depression had a significant impact on it.

Use of the Alcohol Use Disorders Identification Test (AUDIT) to determine the prevalence of alcohol misuse among HIV-infected individuals.

The aim of the paper is to evaluate alcohol misuse among an inner city adult HIV clinic population with AUDIT (Alcohol Use Disorders Identification Test). A cross-sectional HIV outpatient clinic analysis between 28 February 2011 and 11 March 2011 was carried out. AUDIT, demographic and clinical data were collected. Univariate analysis was performed to look for the associations between variables. Backward stepwise multivariate analyses were performed on significant variables from the univariate analysis to assess for predictors of alcohol dependence. In total, 111 patients were included (60% uptake of clinic attendees); 66% were men and 26% were hepatitis C virus (HCV) co-infected. The median AUDIT score was 5 (within normal range). Thirty-four 'AUDIT positive' cases were identified: five (4.5%) indicated consumption of hazardous levels of alcohol; 21 (19%) indicated harmful levels of alcohol; and eight (7%) were likely alcohol dependent. Younger age (<40 years old) was significantly associated with AUDIT positivity (P = 0.006). On multivariate analysis younger age (P = 0.045, odds ratio 13.8) and lower level of education (P = 0.006, odds ratio 6.7) were predictive of scores indicative of alcohol dependence (AUDIT ≥20). In conclusion, younger age and lower educational levels were associated with scores consistent with alcohol dependence. AUDIT was well tolerated and easy to administer in this outpatient HIV clinic population.

HIV-related malignancies pre- and post-highly active antiretroviral therapy: experiences in an inner city tertiary referral centre.

With highly active antiretroviral therapy (HAART), AIDS-defining malignancies are becoming less common. The outcomes with standard chemotherapy are improving. In the last 10 years there have been significant changes in our patient demographics due to immigration. The aim of this study was to review the demographics and outcomes of patients with cancer in the post-HAART era and to assess the impact of changing demographics and HAART through comparing them with previously published pre-HAART data from the same centre. A retrospective chart review of 42 patients diagnosed with malignancy from 2000 to 2007 was performed and compared with pre-HAART (1987-1994) data. The incidence of malignancies has decreased from 5.2% to 2.4%. The incidence of Kaposi's sarcoma and primary cerebral lymphoma has decreased. Non-Hodgkin's lymphoma incidence has remained stable, but survival has improved with 44% of patients achieving remission. Non-AIDS-defining malignancies have increased and were associated with longer duration of HIV infection. The change in patient demographics did not have an impact on the type of malignancies diagnosed. Overall the incidence of malignancy has decreased; however, the increase in non-AIDS-defining malignancies highlights the importance of early diagnosis, use of HAART and prospective surveillance.

Utilization of HIV point-of-care testing clinics in general practice and genitourinary medicine services in south-east London.

We compared the utilization of HIV point-of-care testing (POCT) clinics in a general practice and a genitourinary (GU) medicine service. Retrospective case-note review of patients attending the general practice HIV POCT clinic from February 2005 to July 2007 was undertaken. Those attending the GU medicine service over the same period were used as a comparator group. HIV POCT clinics in general practice when compared with GU medicine services were significantly more likely to be utilized by those of Black ethnicity (Black African 61/370 [16.5%] vs. 107/1231 [8.7%], P < 0.001; Black Caribbean 19/370 [5.1%] vs. 11/1231 [0.9%], P < 0.001 and Black Other 20/370 [5.4%] vs. 26/1231 [2.1%], P = 0.001, respectively). Fewer men who have sex with men attended for HIV POCT in general practice than in GU medicine; 82/238 (34.5%) vs. 337/816 (41.3%), P = 0.058. We have demonstrated that HIV POCT clinics in primary care and GU medicine attract different 'at-risk' groups and provide increased opportunity for testing.
