DAA-based treatment for HIV-HCV-coinfected patients: analysis of factors of sustained virological response in a real-life study.

BACKGROUND: The aim of the present study was to evaluate in HIV-infected patients treated with a direct-acting antiviral agent (DAA)-based regimen the variables associated with sustained virological response (SVR) and the trend in biochemical parameters and clinical events during and after DAA regimen. METHODS: We performed a multicentre retrospective cohort study, enrolling all 243 HIV-HCV-coinfected adult patients treated with DAAs between January 2015 and December 2018 in one of the nine participating Infectious Disease Centers in southern Italy, eight in Campania and one in Apulia. RESULTS: Of the 243 patients enrolled, 233 (95.9%) obtained an SVR at 12 weeks (SVR12). Of the 10 patients with non-SVR, 7 were tested for NS3, NS5A and NS5B resistance-associated substitutions (RASs) by sequencing analysis and 6 showed at least 1 major RAS in 1 HCV region (all in NS5A, 2 in NS5B and 1 in NS3). Comparing the 233 patients achieving SVR and the 10 non-achievers, no variable was independently associated with non-SVR. During and after DAA regimen, no modification in the biochemical parameters and clinical events was observed; however, the serum cholesterol and low-density lipoprotein (LDL) levels showed an increase (from 159 ±41.3 mg/dl at baseline to 174 ±44.5 mg/dl at week 12 after stopping treatment, P<0.001, and from 92 ±34.6 mg/dl to 109.4 ±73.7 mg/dl, P=0.002, respectively). CONCLUSIONS: The treatment with DAAs led to a high SVR12 rate in HIV-HCV-coinfected subjects, irrespective of epidemiological, clinical or virological characteristics. However, the DAA regimen was associated with an increase in total- and LDL-cholesterol, to be taken into account in the management of HIV infection.

Patient-Reported Outcomes in an Observational Cohort of HIV-1-Infected Adults on Darunavir/Cobicistat-Based Regimens: Beyond Viral Suppression.

OBJECTIVE: This prospective, multicenter, non-interventional cohort study enrolling human immunodeficiency virus (HIV)-1-infected, virally suppressed adult outpatients in Italy aimed to describe results obtained from patient-reported outcome questionnaires regarding treatment satisfaction and symptom perceptions in HIV-1-positive patients who switched to cobicistat-boosted darunavir antiretroviral regimens, coming from ritonavir-boosted protease inhibitors. METHODS: Patients entered this study between June 2016 and February 2017, once their treating physician had considered them eligible for cobicistat-boosted darunavir-based treatment as per clinical practice. Patients' satisfaction regarding regimen and current symptom burdens were assessed using two previously validated, patient-reported outcome questionnaires: HIV Treatment Satisfaction Questionnaire (HIV-TSQ) and HIV Symptoms Distress Module (HIV-SDM). These questionnaires were administered at prespecified time-points: enrollment (Visit 1), 4-8 weeks later (Visit 2), and 48 ± 6 weeks after study enrollment (Visit 4). Data of patient-reported outcome total scores for both questionnaires are presented as median with 25th-75th percentiles. Questionnaires scores were analyzed overall and stratified by gender when applicable. A p value of less than 0.05 was considered statistically significant. A sensitivity analysis was conducted to evaluate the role of lost to follow-up, using the "last observation carried forward" method. RESULTS: A total of 348 patients were enrolled in this study; 296 patients (208 male and 88 female) provided both evaluable HIV-TSQ and HIV-SDM at enrollment and at 4-8 weeks, while 250 patients (174 male and 76 female) provided questionnaire data at enrollment and at 48 ± 6 weeks. The total scores of HIV-TSQ showed improvements in patient satisfaction in the overall population both at Visit 2 and Visit 4 (p < 0.001, sign test) and also when stratified by gender throughout the study period. In addition, the overall burden of symptoms, as shown by the HIV-SDM scores, decreased. CONCLUSIONS: Switching to a cobicistat-boosted darunavir-based therapy led to overall increased patient satisfaction and reduced symptom burden when compared with previous regimens. The use of patient-reported outcomes in clinical daily practice could provide a useful tool towards achieving guideline goals to achieve "fourth 90", having 90% of virally suppressed patients with a good health-related quality of life.

[Use of PCR for TB bacteria on BAL in early diagnosis of tubercular lobitis]. / PCR per BK su BAL nella diagnostica precoce di lobite tubercolare.

In June 2008 a 23-year-old immunocompetent came to our observation, without fever and with an occasional cough for 2 months, who showed two chest X-rays and a CT, performed respectively 60, 40 and 20 days earlier, that pointed to a small lobitis at the right lung base. The patient had already undergone several antibiotic therapies that had not changed the X-graphic framework. On presentation, routine blood tests and cultural examinations of sputum were carried out to detect common germs, fungi and TB bacteria (microscopic observation, cultivation and PCR), and a new antibiotic therapy (piperacillin/tazobactam) was started. Since the radiological picture appeared unchanged after 10 days of therapy and the examinations (microscopic observation and PCR) were negative, bronchoscopy with bacteriological evaluation of BAL was performed, which was positive to Mycobacterium tuberculosis, and then tubercular lobitis was diagnosed. Therefore a specific therapy - rifampin (RMP), isoniazid (INH), etambutol (EMB), pyrazinamid (PZA) - was started and changed after 10 days due to the growth of mycobacteria resistant to INH and EMB on examination of sputum. Consequently, the early use of PCR on BAL allows, in skilled hands, small aspecific lobitis to be diagnosed more rapidly than using cultural examination of sputum.

[Sexual exposure to HIV, sexual behaviour and use of pharmacological post-exposure prophylaxis (PEP)]. / Esposizione sessuale al virus HIV, comportamenti sessuali ed utilizzo della profilassi farmacologica post- esposizione (PEP).

In this study we examined the characteristics of 60 subjects (49 M and 11 F, average age 32.3) out of 195 post-exposure pharmacological prophylaxis (PEP) to HIV, taken in our hospital from 2001 to 2008. The above-mentioned subjects are sexually exposed (or presumably exposed) to HIV. We considered both their sexual intercourse behaviour and protective measures, and sought to infer some trends in sexual behaviour in Italy. All the subjects were monitored until 180 days after exposure, as established by the national guidelines. Only one of the 60 people presented a seroconversion (he dropped out after a 15-day follow-up and after an inadequate 19-day prophylaxis). Another subject, a homosexual male, never previously tested, resulted positive at time 0 both for HIV-Ab and syphilis tests (due to previous risk-sexual exposure), which caused the suspension of the prophylaxis. No HBV, HCV or syphilis seroconversion occurred. Two other homosexual males showed a previously latent positivity to syphilis tests at time 0.

Clinical case of seroconversion for syphilis following a needlestick injury: why not take a prophylaxis?

A 47-year-old woman was pricked accidentally with a needle previously used for a neurosyphilitic man. At day 0 she had no positive laboratory results for the infection, while the source, at day 1, had TPHA positive, but no post-exposure prophylaxis (PEP) against syphilis was prescribed. The subject missed the day 30 follow-up, and underwent our visit at day 90, when she showed no clinical signs, but she seroconverted (VDRL = positive 1/2; TPHA = positive 1/320; FTA-Abs IgG and IgM = present). She started antibiotic therapy, and currently her serological status is VDRL = positive 1/2, TPHA = positive 1/160, FTA-Abs IgM = negative.
