RESUMEN
BACKGROUND: Doravirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI) showing high efficacy and tolerability in both naïve and experienced people living with HIV (PLWHIV) in randomized trials, but scarce data are available to date from the real-life experience. METHODS: We performed an observational, retrospective study of PLWHIV on suppressive antiretroviral therapy who switched to a daily single-tablet regimen containing doravirine 100 mg, lamivudine 300 mg, and tenofovir disoproxil fumarate 300 mg. RESULTS: As a whole, 62 suppressed patients (51 men, median age, 51.7 years; median CD4 T+ lymphocyte count, 577 cells/mm3) were enrolled. After 12 months, 58 (93.5%) patients showed HIV RNA <20 copies/mL and reasons for treatment failure were virological failure in one case, missing data in one case, and adverse events in two cases. At month 12, a significant decrease in median serum level of triglycerides (median change -61.2 mg/dL; p = .009) and total cholesterol (median change -38.4 mg/dL; p = .021) was reported, while a not significant median weight increase was registered (+0.55 kg). CONCLUSIONS: In our study, simplification to a single-tablet regimen of doravirine/lamivudine/tenofovir disoproxil fumarate in virologically suppressed PLWHIV was effective and showed a good tolerability profile, in association with a significant improvement in serum lipid levels.

OBJECTIVES: The effectiveness of omega-3 fatty acids (PUFAs) in cardiovascular diseases (CVD) remains a matter of debate. The aim of this work was to evaluate PUFAs in the reduction of cardiovascular mortality in primary and secondary prevention of CVD to determine if further original studies are needed or the available data can be considered conclusive. METHODS: A meta-analysis was performed according to a dichotomous endpoint followed by a trial-sequential analysis (TSA). Clinical data were identified through a PubMed search based on the following keywords: omega-3 fatty acids; cardiovascular disease; death; and cardiovascular risk. The clinical trials identified by this procedure were subjected to standard meta-analysis and TSA. RESULTS AND CONCLUSIONS: A total of 11 randomised studies for 100 609 patients were analysed. Our meta-analysis showed a statistically significant reduction in mortality due to cardiovascular issues (RR=0.937; 95% CI: 0.88 to 0.98; P=0.018). The TSA indicated that no further trials are needed to better evaluate the efficacy of PUFAs in preventing death related to CVD.

OBJECTIVE: To assess the incidence of colonization and infection with carbapenemase-producing Enterobacteriaceae (CPE) and carbapenem-resistant Acinetobacter baumannii (CR-Ab) in the ICUs of our city hospitals before and during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: We conducted a multicenter, before-and-after, cross-sectional study to compare the rates of colonization and infection with CPE and/or CR-Ab in 2 study periods, period 1 (January-April 2019) and period 2 (January-April 2020). Incidence rate ratios (IRRs) and 95% confidence intervals (CIs) of weekly colonization and infection rates for each period were compared for the 2 study periods using Poisson regression. Weekly trends in the incidence of colonization or infection for each study period were summarized using local weighted (Loess) regression. RESULTS: We detected no significant change in either IRR and weekly trend in CPE colonization and infection during the 2 study periods. A shift from KPC to other CPE mechanisms (OXA-48 and VIM) was observed during period 2. Compared to period 1, during period 2 the IRR of colonization and infection with CR-Ab increased 7.5- and 5.5-fold, respectively. Genome sequencing showed that all CR-Ab strains belonged to the CC92/IC2 clonal lineage. Clinical strains clustered closely into a single monophyletic group in 1 of the 3 centers, whereas they segregated in 2 different clusters in the other 2 centers, which strongly indicates horizontal transmission. CONCLUSIONS: Our findings indicate the need to conduct infection control activities targeted against the spread of antimicrobial resistance between and within hospitals during the COVID-19 pandemic, and if necessary, remodulating them according to the new organizational structures imposed by the pandemic.

In our HIV outpatient centre where over 1,200 patients are followed, maraviroc as an entry inhibitor was introduced in 2010. We aimed to assess the background, the therapeutic challenges and the prospective monitoring of all patients treated with a combination antiretroviral therapy (cART) including maraviroc. Sixty-six patients started a maraviroc-containing cART with a history of HIV infection lasting 13.9±10.7 years. This interim analysis presents patients who had at least 12 (mean 16.9±12.8) months of follow-up. One to 17 previous cART changes prompted the introduction of maraviroc in rescue regimens in the great majority of patients considered (53 of 66); in 13 cases, maraviroc was given to patients with advanced HIV disease and no immune recovery after 2-3 years of a virologically-effective cART. The most frequent companion antiretroviral agents were: darunavir/ritonavir (51 cases), raltegravir (49 subjects), and etravirine (36 cases). The most common underlying conditions were: AIDS (41 cases), liver cirrhosis (21), AIDS-related or other malignancies (20 cases), major cardiovascular events (18 cases), osteonecrosis and haemodialysis-treated kidney failure (3 cases each). A chronic HCV and HBV hepatitis were of concern in 25 and 13 patients. The addition of maraviroc added favourably to clinical-laboratory markers of HIV disease progression, and those of comorbid conditions. HIV viraemia became (or remained) undetectable in 55 patients of 66 (83.3%). An improvement in CD4+ count was observed in all 66 patients, based on a mean 24.9±19.2% increase versus baseline, paralleled by an improvement in mean absolute CD4+ count of 134.7±121.1 cells/µL. A tendency towards an increased mean and peak CD4+ count was observed in the subgroup receiving a maraviroc-raltegravir-based cART. As no clinical-laboratory adverse events attributable to maraviroc occurred, nobody discontinued the study drug. Only mild-transient gastrointestinal disturbances, fatigue and anorexia, were reported during maraviroc administration, but their relationship with the study drug was difficult to assess because of the multiple comorbidities and polypharmacy. Our preliminary experience with maraviroc, even considering the limits of the proportionally reduced sample, the patients' salvage stage of advanced disease and the related-unrelated morbidities, underlines its excellent efficacy and safety profile.

To evaluate the frequency of myopathy and serum creatine kinase (CK) elevation associated with the use of the integrase inhibitor raltegravir we conducted a retrospective, cohort analysis assessing the incidence of skeletal muscle toxicity among HIV-infected patients treated with raltegravir. Adult HIV-infected patients who started a raltegravir-containing therapy were enrolled into the study. The skeletal muscle toxicity was defined by the presence of one or more of the following parameters: (1) isolated and significant CK elevation without signs or symptoms; (2) diffuse myalgia without weakness; (3) proximal muscle weakness; (4) rhabdomyolysis. On the whole, 155 patients were included in the study, with a mean age of 49.2 years; the median duration of the raltegravir treatment was 30.7 months. The overall frequency of skeletal muscle toxicity was 23.9%, with an incidence of 4.7/100 person-years. An isolated CK elevation was reported in 21.3% of cases, while less than 3% of patients complained of myalgia or muscle weakness. The CK elevation was usually of grade 1 or 2 and self-limiting, and laboratory or clinical abnormalities did not require discontinuation of raltegravir in any patient. Factors significantly associated with skeletal muscle toxicity were previous use of zidovudine, higher baseline CK levels, previous increase of the CK levels, and a higher body mass index. Skeletal muscle toxicity is not an unusual adverse event in subjects receiving raltegravir, but it is usually represented by a mild-to-moderate increase in CK concentration, while clinical symptoms of myopathy are very uncommon.

Permanent monitoring of adherence to combination antiretroviral therapy (cART), together with the assessment and management of related adverse events, plays a key role for optimised management of HIV infection. In our HIV outpatient clinic a dedicated pharmacist provides direct drug distribution and accountability, and gives information on administration mode, possible side effects and drug interactions. A survey card regarding cART adherence and adverse drug reactions (ADRs) is administered to all patients. All figures are recorded in an electronic database. In an ad interim analysis 659 consecutive patients' data were evaluated, of whom 74% were fully adherent to cART. A lower adherence rate was found to be correlated with the presence of concurrent medications, and with the increasing number of daily cART tablets/capsules. A significant impact of cART adherence on a favourable course of the main laboratory surrogate markers of HIV disease progression (CD4+ T-lymphocyte count and HIV viral load) was also observed. Darunavir-containing cART was related to a lower incidence of early gastrointestinal and neuropsychiatric disturbances and also a reduced perception of morphological/physical changes. A multidisciplinary approach based on strict interaction between pharmacists and infectious diseases physicians may significantly improve cART adherence and the monitoring of adverse events, making a considerable contribution to the better management of HIV-infected patients.

Raltegravir, as the first HIV integrase inhibitor, has been used and prospectively monitored since 2010 in our HIV outpatient centre, where over 1,200 patients are monitored. The aim of our report is to perform an interim assessment of the background, the safety profile and the clinical-laboratory monitoring of all patients treated with a combination antiretroviral therapy (cART) including raltegravir, for at least 12 months. In all, 109 pretreated patients started a raltegravir-containing cART when aged 44.8 plus or minus 19.2 years, with a history of HIV infection lasting 13.4 plus or minus 9.7 years. All subjects were monitored for at least 12 months (mean 17.2 plus or minus 10.3 months). In the vast majority of cases (93 of 109: 85.3%), multiple (3-16) prior cART changes prompted raltegravir introduction in advanced-salvage lines: 72 of 109 (66.1%) patients had even developed a concurrent triple-class resistance to anti-HIV compounds. The most frequent companion antiretroviral agents were: darunavir/ritonavir (75 cases), maraviroc (47 subjects), and etravirine (38 cases). The most common underlying conditions were: AIDS (46 patients), liver cirrhosis (31 cases), AIDS-related or other malignancies (23 cases), and major cardio-cerebro-vascular events (18 cases). A chronic HCV and HBV hepatitis were of concern in 48 and 23 patients, respectively. The adjunct of raltegravir favourably affected all clinical-laboratory markers of HIV disease progression, and those of the broad spectrum of comorbidities, except for two patients who failed the raltegravir-containing cART due to insufficient adherence. Despite the already compromised clinical situation, a minority of subjects experienced mild-transient clinical-laboratory untoward events possibly attributable to raltegravir, such that no patients discontinued raltegravir during the observation period. Only three AIDS-defining conditions became apparent during raltegravir-based cART; chemotherapy and/or radiotherapy cycles were performed as scheduled in patients suffering from cancer; chronic hepatitis B and C progressed to liver cirrhosis and/or hepatocarcinoma in only 2 and 6 patients. Otherwise, treatment with pegylated interferon-ribavirin became feasible in 25 patients of 48 with chronic HCV. During raltegravir-containing cART, neither autoimmune disorders nor novel malignancies were diagnosed. Only mild-transient gastrointestinal disorders, fatigue, dizziness, insomnia and cutaneous rash were reported, although their relationship with the study drug was difficult to assess due to multiple comorbidities and polypharmacy. Abnormal liver function testings were observed in 57 patients (52.3%), all suffering from concurrent hepato-biliary disorders. Significant increases in serum lipids and/or lipase levels versus baseline values were never registered: serum lipid levels significantly improved after raltegravir introduction. Our experience with raltegravir underlines its excellent efficacy and safety profile, which exploits a novel mechanism of action, and displays no cross-resistance with any other antiretroviral. A progressively extended prescription in naive patients and early cART lines will allow the therapeutic potential of raltegravir to be exploited.
