HCV reinfection after HCV therapy among HIV/HCV-coinfected individuals in Europe.

OBJECTIVES: Although direct-acting antivirals (DAAs) can clear HCV in nearly all HIV/HCV-coinfected individuals, high rates of reinfection may hamper efforts to eliminate HCV in this population. We investigated reinfection after sustained virological response (SVR) in HIV/HCV-coinfected individuals in Europe. METHODS: Factors associated with odds of reinfection by 2 years after SVR in EuroSIDA participants with one or more HCV-RNA test and 2 years follow-up were assessed using logistic regression. RESULTS: Overall, 1022 individuals were included. The median age was 50 (interquartile range: 43-54 years), and most were male (78%), injection drug users (52%), and received interferon (IFN)-free DAAs (62%). By 24 months, 75 [7.3%, 95% confidence interval (CI): 5.7-8.9%] individuals were reinfected. Among individuals treated prior to 2014, 16.1% were reinfected compared with 4.2% and 8.3%, respectively, among those treated during or after 2014 with IFN-free and IFN-based therapy. After adjustment, individuals who had started treatment during or after 2014 with IFN-free or IFN-based therapy had significantly lower odds of reinfection (adjusted odds ratio = 0.21, 95% CI: 0.11-0.38; 0.43, 95% CI: 0.22-0.83) compared with those who had received therapy before 2014. There were no significant differences in odds of reinfection according to age, gender, European region, HIV transmission risk group or liver fibrosis. CONCLUSIONS: Among HIV/HCV-coinfected individuals in Europe, 7.3% were reinfected with HCV within 24 months of achieving SVR, with evidence suggesting that this is decreasing over time and with use of newer HCV regimens. Harm reduction to reduce reinfection and surveillance to detect early reinfection with an offer of treatment are essential to eliminate HCV.

Proactive Prophylaxis With Azithromycin and HydroxyChloroquine in Hospitalised Patients With COVID-19 (ProPAC-COVID): A structured summary of a study protocol for a randomised controlled trial.

OBJECTIVES: The aim of this randomised GCP-controlled trial is to clarify whether combination therapy with the antibiotic azithromycin and hydroxychloroquine via anti-inflammation/immune modulation, antiviral efficacy and pre-emptive treatment of supra-infections can shorten hospitalisation duration for patients with COVID-19 (measured as "days alive and out of hospital" as the primary outcome), reduce the risk of non- invasive ventilation, treatment in the intensive care unit and death. TRIAL DESIGN: This is a multi-centre, randomised, Placebo-controlled, 2-arm ratio 1:1, parallel group double-blind study. PARTICIPANTS: 226 participants are recruited at the trial sites/hospitals, where the study will take place in Denmark: Aalborg, Bispebjerg, Gentofte, Herlev, Hillerød, Hvidovre, Odense and Slagelse hospitals. INCLUSION CRITERIA: • Patient admitted to Danish emergency departments, respiratory medicine departments or internal medicine departments • Age≥ 18 years • Hospitalized ≤48 hours • Positive COVID-19 test / diagnosis during the hospitalization (confirmed). • Men or non-fertile women. Fertile women* must not be pregnant, i.e. negative pregnancy test must be available at inclusion • Informed consent signed by the patient *Defined as after menarche and until postmenopausal (no menstruation for 12 months) Exclusion criteria: • At the time of recruitment, the patient uses >5 LO2/min (equivalent to 40% FiO2 if measured) • Known intolerance/allergy to azithromycin or hydroxychloroquine or hypersensitivity to quinine or 4-aminoquinoline derivatives • Neurogenic hearing loss • Psoriasis • Retinopathy • Maculopathy • Visual field changes • Breastfeeding • Severe liver diseases other than amoebiasis (INR> 1.5 spontaneously) • Severe gastrointestinal, neurological and hematological disorders (investigator-assessed) • eGFR <45 ml/min/1.73 m2 • Clinically significant cardiac conduction disorders/arrhythmias or prolonged QTc interval (QTc (f) of> 480/470 ms). • Myasthenia gravis • Treatment with digoxin* • Glucose-6-phosphate dehydrogenase deficiency • Porphyria • Hypoglycaemia (Blood glucose at any time since hospitalization of <3.0 mmol/L) • Severe mental illness which significantly impedes cooperation • Severe linguistic problems that significantly hinder cooperation • Treatment with ergot alkaloids *The patient must not be treated with digoxin for the duration of the intervention. For atrial fibrillation/flutter, select according to the Cardiovascular National Treatment Guide (NBV): Calcium antagonist, Beta blocker, direct current (DC) conversion or amiodarone. In case of urgent need for digoxin treatment (contraindication for the aforementioned equal alternatives), the test drug should be paused, and ECG should be taken daily. INTERVENTION AND COMPARATOR: Control group: The control group will receive the standard treatment + placebo for both types of intervention medication at all times. If part or all the intervention therapy being investigated becomes standard treatment during the study, this may also be offered to the control group. Intervention group: The patients in the intervention group will also receive standard care. Immediately after randomisation to the intervention group, the patient will begin treatment with: Azithromycin: Day 1-3: 500 mg x 1 Day 4-15: 250 mg x 1 If the patient is unable to take the medication orally by themselves, the medication will, if possible, be administered by either stomach-feeding tube, or alternatively, temporary be changed to clarithromycin 500 mg x 2 (this only in agreement with either study coordinator Pradeesh Sivapalan or principal investigator Jens-Ulrik Stæhr Jensen). This will also be done in the control group if necessary. The patient will switch back to azithromycin when possible. Hydroxychloroquine: Furthermore, the patient will be treated with hydroxychloroquine as follows: Day 1-15: 200 mg x 2 MAIN OUTCOMES: • Number of days alive and discharged from hospital within 14 days (summarises both whether the patient is alive and discharged from hospital) ("Days alive and out of hospital") RANDOMISATION: The sponsor (Chronic Obstructive Pulmonary Disease Trial Network, COP:TRIN) generates a randomisation sequence. Randomisation will be in blocks of unknown size and the final allocation will be via an encrypted website (REDCap). There will be stratification for age (>70 years vs. <=70 years), site of recruitment and whether the patient has any of the following chronic lung diseases: COPD, asthma, bronchiectasis, interstitial lung disease (Yes vs. No). BLINDING (MASKING): Participants and study personnel will both be blinded, i.e. neither will know which group the participant is allocated to. NUMBERS TO BE RANDOMISED (SAMPLE SIZE): This study requires 226 patients randomised 1:1 with 113 in each group. TRIAL STATUS: Protocol version 1.8, from April 16, 2020. Recruitment is ongoing (first patient recruited April 6, 2020; final patient expected to be recruited October 31, 2020).

In the interest in expediting dissemination of this material, the familiar formatting has been eliminated; this Letter serves as a summary of the key elements of the full protocol. The study protocol has been reported in accordance with the Standard Protocol Items: Recommendations for Clinical Interventional Trials (SPIRIT) guidelines (Additional file 2).

Improving the evidence for indicator condition guided HIV testing in Europe: Results from the HIDES II Study - 2012 - 2015.

BACKGROUND: It is cost-effective to perform an HIV test in people with specific indicator conditions (IC) with an undiagnosed HIV prevalence of at least 0.1%. Our aim was to determine the HIV prevalence for 14 different conditions across 20 European countries. METHODS: Individuals aged 18-65 years presenting for care with one of 14 ICs between January 2012 and June 2014 were included and routinely offered an HIV test. Logistic regression assessed factors associated with testing HIV positive. Patients presenting with infectious mononucleosis-like syndrome (IMS) were recruited up until September 2015. RESULTS: Of 10,877 patients presenting with an IC and included in the analysis, 303 tested positive (2.8%; 95% CI 2.5-3.1%). People presenting with an IC in Southern and Eastern Europe were more likely to test HIV positive as were people presenting with IMS, lymphadenopathy and leukocytopenia/ thrombocytopenia. One third of people diagnosed with HIV after presenting with IMS reported a negative HIV test in the preceding 12 months. Of patients newly diagnosed with HIV where data was available, 92.6% were promptly linked to care; of these 10.4% were reported lost to follow up or dead 12 months after diagnosis. CONCLUSION: The study showed that 10 conditions had HIV prevalences > 0.1%. These 10 ICs should be adopted into HIV testing and IC specialty guidelines. As IMS presentation can mimic acute HIV sero-conversion and has the highest positivity rate, this IC in particular affords opportunities for earlier diagnosis and public health benefit.

HIV testing in Europe: Evaluating the impact, added value, relevance and usability of the European Centre for Disease Prevention and Control (ECDC)'s 2010 HIV testing guidance.

BACKGROUND: An evaluation of the 2010 ECDC guidance on HIV testing, conducted in October 2015-January 2016, assessed its impact, added value, relevance and usability and the need for updated guidance. METHODS: Data sources were two surveys: one for the primary target audience (health policymakers and decision makers, national programme managers and ECDC official contact points in the European Union/European Economic Area (EU/EEA) countries and one for a broader target audience (clinicians, civil society organisations and international public health agencies); two moderated focus group discussions (17 participants each); webpage access data; a literature citation review; and an expert consultation (18 participants) to discuss the evaluation findings. RESULTS: Twenty-three of 28 primary target audience and 31 of 51 broader target audience respondents indicated the guidance was the most relevant when compared with other international guidance. Primary target audience respondents in 11 of 23 countries reported that they had used the guidance in development, monitoring and/or evaluation of their national HIV testing policy, guidelines, programme and/or strategy, and 29 of 51 of the broader target audience respondents reported having used the guidance in their work. Both the primary and broader target audience considered it important or very important to have an EU/EEA-level HIV testing guidance (23/28 and 46/51, respectively). CONCLUSION: The guidance has been widely used to develop policies, guidelines, programmes and strategies in the EU/EEA and should be regularly updated due to continuous developments in the field in order to continue to serve as an important reference guidance in the region.

Use of antiretroviral therapy and risk of end-stage liver disease and hepatocellular carcinoma in HIV-positive persons.

OBJECTIVES: Although several antiretroviral drugs, including the d-drugs stavudine (d4T) and didanosine (ddI), may cause biomarker-defined hepatotoxicity, their association with clinically defined end-stage liver disease (ESLD) and hepatocellular carcinoma (HCC) remains unknown. DESIGN: Prospective cohort study. METHODS: Data collection on adverse events of anti-HIV drugs study (D:A:D) participants were followed until the first of ESLD (variceal bleeding, hepatic encephalopathy, hepatorenal syndrome or liver transplantation), HCC (histology or α-fetoprotein along with imaging), death, 6 months after last visit or 1 February 2014. Associations between ESLD/HCC and cumulative use of individual antiretrovirals were investigated using Poisson regression adjusting for potential confounders. RESULTS: During a median follow-up of 8.4 years, 319 ESLD/HCC cases occurred [incidence 1.01/1000 person-years (95% confidence interval 0.90-1.12)] with a 1-year mortality rate of 62.6%. After adjustment, cumulative (per 5 years) exposure to d4T [relative rate 1.46 (95% confidence interval 1.20-1.77)], ddI [1.32 (1.07-1.63)], tenofovir [TDF, 1.46 (1.11-1.93)] and (fos)amprenavir [APV; 1.47 (1.01-2.15)] was associated with increased ESLD/HCC rates. Longer exposure to emtricitabine [0.51 (0.32-0.83)] and nevirapine [0.76 (0.58-0.98)] were associated with lower ESLD/HCC rates. The ddI/d4T-associated increased ESLD/HCC rate only started to decline 6 years after cessation. CONCLUSION: Cumulative use of d4T, ddI, TDF and APV were independently associated with increased ESLD/HCC rates, and intensified monitoring of liver function should hence be considered among all individuals exposed for longer time periods. The use of d-drugs should furthermore be avoided, where there are alternatives available, and focus should be put on those with longer-term d-drugs exposure who remain at increased ESLD/HCC risk. The unexpected, and viral hepatitis-independent, TDF association calls for further investigations.
