RESUMO

BACKGROUND: Oral human papillomavirus (HPV) is common among healthy individuals but causes and implications of persistent infections are under evaluation in the pathogenesis of head and neck neoplasms. METHODS: This was a retrospective study evaluating the prevalence of high-risk (HR), probable HR and low-risk (LR) HPV types in patients reporting signs/symptoms of oral and upper respiratory tract lesions. Individuals attending between 2019 and 2022 a University Hospital in Milan, Italy, with risk factors for HPV (unprotected oral sex and/or previous documentation of HPV infection in oral and upper respiratory tract and/or another anatomical site) were included. RESULTS: Fourteen out of 110 (12.7%) individuals tested positive for HPV DNA. The prevalence of HR-HPV and LR-HPV was 3.6% (4/110) and 9.1% (10/110), respectively. No probable/possible HR-HPV was detected. Specifically, 10/110 (9.1%) were diagnosed with 1 LR-HPV genotype, 3/110 (2.7%) were infected with 1 HR-HPV and 1/110 had 3 concomitant HR-HPV types. HPV 16 (2.7%, 3/110) and 6 (4.5%, 5/110) were the most common HR and LR types, respectively. One patient positive for HPV 16, 33 and 35 was diagnosed with cancer at the base of the tongue. Two individuals among those who tested positive for HPV DNA reported previous HPV vaccination. CONCLUSIONS: Our data, in line with observations from previous prevalence studies, support the potential role of HPV in head and neck neoplasms. HPV DNA testing should be performed in patients presenting lesions in oral/respiratory tracts and risk factors for HPV. Improvement in HPV vaccination coverage is warranted.

RESUMO

Human papillomavirus (HPV) is the most common sexually transmitted infection, linked to several types of lesions. HPV, specifically HPV 16, accounts for most of anal cancer cases. In this study, we evaluated the proportion of samples tested positive for HPV and characterized genotypes distribution in anal specimens collected from individuals at risk of anal HPV infection attending from 2018 to 2022 a large Infectious Diseases Department in Italy. The presence of HPV DNA was investigated through a commercial kit detecting 12 HR-HPV, 8 probable/possible HR-HPV, and 8 LR-HPV genotypes. Among 1514 samples, 84% (1266/1514) resulted positive for any type of HPV. The prevalence of high-risk HPV types remained high during all the years of the study period, from 2018 to 2022, ranging from 65% to 73%. Most of HR-HPV, LR-HPV and HPV 16 positive samples were collected from men >45 years. HPV 16 was also the most frequent type in men and women. We did not observe significant variations between years in detection of HR-HPV, instead of LR-HPV, that significantly decreased. In conclusion, the high prevalence of oncogenic HPV genotypes underlines the necessity of clear anal HPV screening guidelines and, along with frequent HR-HPV coinfections, reinforces the urge to intensify the anti-HPV vaccination campaign.

RESUMO

BACKGROUND: Predictors of Respiratory Syncytial Virus (RSV) infection and determinants of RSV unfavorable outcomes are still unclear. We assessed RSV burden and investigated the risk factors associated with RSV positive swab and RSV severe disease. METHODS: A retrospective, single center, cohort study included all consecutive patients referred to the emergency department of L. Sacco University Hospital (Milan) with flu-like symptoms or acute respiratory failure (aRF) tested per protocol for SARS-CoV-2, RSV, Influenza A (InvA) during the 2022-2023 autumn/winter season. Clinical characteristics and patients' outcomes were registered. Respiratory failure, need for respiratory support, shock, sepsis or in-hospital death defined severe disease. MAIN FINDINGS: The analysis included 717 patients (65.1% negative swab, 14.1% InvA, 8.5% RSV, 8.6% SARS-CoV-2, 3.6% other viruses). Compared with the study cohort, RSV patients had the highest occurrence of aRF (62.7%) and severe disease (70.5%); mortality was similar to InvA (6.6% vs 5.9%, p = 0.874). Compared with InvA patients, RSV patients were older (p = 0.009), had higher Charlson index (p = 0.001), higher prevalence of chronic heart failure (p = 0.001) and were more frequently on ICS (p = 0.026) and immunosuppressants (p = 0.018). Heart failure [OR (95%CI):3.286 (1.031-10.835); p = 0.041], chronic exposure to ICS [OR (95%CI):2.377 (1.254-4.505); p = 0.008] and immunosuppressants [OR (95%CI):3.661 (1.246-10.754); p = 0.018] predicted RSV infection. Glycaemia ≥120 mg/dL [OR (95%CI):5.839 (1.155-29.519); p = 0.033], leucocytes ≥8000 cells/µL [OR (95%CI):5.929 (1.090-32.268); p = 0.039], and past/active smoking [OR (95%CI):7.347 (1.301-41.500); p = 0.024] predicted severe RSV disease. CONCLUSIONS: RSV infection is associated with significant mortality and morbidity. Preventive strategies for RSV infection such as vaccination are highly warranted, especially in older patients with cardiovascular and chronic respiratory conditions.

RESUMO

In 2022, we opened an outpatient clinic for the management of polypharmacy and potential drug-drug interactions (pDDIs) in patients with mycobacterial infection (called GAP-MyTB). All patients who underwent a GAP-MyTB visit from March 2022 to March 2023 were included in this retrospective analysis. Fifty-two patients were included in the GAP-MyTB database. They were given 10.4 ± 3.7 drugs (2.8 ± 1.0 and 7.8 ± 3.9 were, respectively, antimycobacterial agents and co-medications). Overall, 262 pDDIs were identified and classified as red-flag (2%), orange-flag (72%), or yellow-flag (26%) types. The most frequent actions suggested after the GAP-MyTB assessment were to perform ECG (52%), therapeutic drug monitoring (TDM, 40%), and electrolyte monitoring (33%) among the diagnostic interventions and to reduce/stop proton pump inhibitors (37%), reduce/change statins (14%), and reduce anticholinergic burden (8%) among the pharmacologic interventions. The TDM of rifampicin revealed suboptimal exposure in 39% of patients that resulted in a TDM-guided dose increment (from 645 ± 101 to 793 ± 189 mg/day, p < 0.001). The high prevalence of polypharmacy and risk of pDDIs in patients with mycobacterial infection highlights the need for ongoing education on prescribing principles and the optimal management of individual patients. A multidisciplinary approach involving physicians and clinical pharmacologists could help achieve this goal.

RESUMO

BACKGROUND AND AIM: The World Health Organization (WHO) goal of hepatitis C virus (HCV) elimination by 2030 relies on the scaling-up of both identification and linkage to care of the infected population, worldwide. In Italy, the estimated burden of HCV carriers who are unaware of their infection amounts to 200 000 persons, a projection that reinforces the need for broadening population access to effective screening programmes. METHODS: A pivotal screening programme targeting subjects born between 1969 and 1989 has been conducted in Lombardy, Northern Italy, where point-of-care (POC) testing was offered for free concomitantly to COVID-19 vaccination. RESULTS: Amongst 7219 subjects born between 1969 and 1989 who underwent HCV screening through POC, 7 (0.10%) subjects tested anti-HCV positive: 5 (0.07%) had confirmed anti-HCV positivity (Table 1) and 4 of them (0.05%) were HCV-RNA positive by standard confirmation tests. CONCLUSIONS: This pivotal study demonstrated the feasibility of a POC-based anti-HCV screening programme in young adults undergoing COVID-19 vaccination. The prevalence of HCV infection in subjects born in the 1969-1989 cohort in Italy seems to be lower than previously estimated. Whether the extension of this programme to subjects born before 1969 could lead to improved screening effectiveness should be a matter of debate.

RESUMO

INTRODUCTION: We report the 48-week results of an ongoing study to assess the efficacy and safety of switching older people with HIV to bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF). METHODS: This was a 96-week, phase 3b, open-label, single-arm study (GS-US-380-4449; NCT03405935). Virologically suppressed individuals aged ≥ 65 years receiving elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide or a tenofovir disoproxil fumarate-based regimen were switched to B/F/TAF. Primary endpoint was the percentage of participants with HIV-1 RNA < 50 copies/ml at week 24. RESULTS: Eighty-six participants (median age 69 [range 65-80] years; 87% male; 95% white) were enrolled and treated in five European countries. Rates of virologic suppression were 97.7% at week 24 and 90.7% at week 48; none had HIV-1 RNA ≥ 50 copies/ml, and 100% had virologic suppression by missing = excluded analysis at both time points. No treatment-emergent resistance was observed. There were no grade 3-4 study drug-related adverse events (AEs) or study drug-related serious AEs or deaths. Three AEs led to premature discontinuation; one (moderate abdominal discomfort) was attributed to the study drug by the investigator. At week 48, median changes from baseline in weight and estimated glomerular filtration rate were + 0.1 kg (interquartile range [IQR] - 1.0, 2.3) and - 6.0 ml/min (IQR - 10.2, 0.0), respectively. There were no clinically relevant changes from baseline to week 48 in fasting lipid parameters. Treatment satisfaction improved, and health-related quality of life was maintained from baseline through week 48. Median adherence to the study drug was 98.6% (IQR 96.0, 100). CONCLUSIONS: Switching to B/F/TAF was effective and well tolerated through 48 weeks in virologically suppressed adults aged ≥ 65 years. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT03405935.

RESUMO

BACKGROUND: It is unclear whether patients with inflammatory bowel disease (IBD) are at increased risk of COVID-19. OBJECTIVES: This observational study compared the prevalence of COVID-19 symptoms, diagnosis and hospitalization in IBD patients with a control population with non-inflammatory bowel disorders. METHODS: This multicentre study, included 2733 outpatients (1397 IBD patients and 1336 controls), from eight major gastrointestinal centres in Lombardy, Italy. Patients were invited to complete a web-based questionnaire regarding demographic, historical and clinical features over the previous 6 weeks. The prevalence of COVID-19 symptoms, diagnosis and hospitalization for COVID-19 was assessed. RESULTS: 1810 patients (64%) responded to the questionnaire (941 IBD patients and 869 controls). IBD patients were significantly younger and of male sex than controls. NSAID use and smoking were more frequent in controls. IBD patients were more likely treated with vitamin-D and vaccinated for influenza. Highly probable COVID-19 on the basis of symptoms and signs was less frequent in the IBD group (3.8% vs 6.3%; OR:0.45, 95%CI:0.28-0.75). IBD patients had a lower rate of nasopharyngeal swab-PCR confirmed diagnosis (0.2% vs 1.2%; OR:0.14, 95%CI:0.03-0.67). There was no difference in hospitalization between the groups (0.1% vs 0.6%; OR:0.14, 95%CI:0.02-1.17). CONCLUSION: IBD patients do not have an increased risk of COVID-19 specific symptoms or more severe disease compared with a control group of gastroenterology patients.

RESUMO

BACKGROUND: Coronavirus disease 2019 (COVID-19) has been associated to microvascular alterations. We screened the fundus of patients with COVID-19 to detect alterations of the retina and its vasculature and to assess possible correlations with clinical parameters. METHODS: Cross-sectional study. The presence of retinal alterations in patients with COVID-19 and subjects unexposed to the virus was assessed using fundus photographs and their prevalence was compared. Mean arteries diameter (MAD) and mean veins diameter (MVD) were compared between patients and unexposed subjects with multiple linear regression including age, sex, ethnicity, body mass index, smoking/alcohol consumption, hypertension, hyperlipidaemia, diabetes as covariates. The influence of clinical/lab parameters on retinal findings was tested in COVID-19 patients. FINDINGS: 54 patients and 133 unexposed subjects were enrolled. Retinal findings in COVID-19 included: haemorrhages (9·25%), cotton wools spots (7·4%), dilated veins (27·7%), tortuous vessels (12·9%). Both MAD and MVD were higher in COVID-19 patients compared to unexposed subjects (98·3 ± 15·3 µm vs 91·9 ± 11·7 µm, p = 0.006 and 138·5 ± 21·5 µm vs 123·2 ± 13·0 µm, p<0.0001, respectively). In multiple regression accounting for covariates MVD was positively associated with COVID-19 both in severe (coefficient 30·3, CI95% 18·1-42·4) and non-severe (coefficient 10·3, CI95% 1·6-19·0) cases compared to unexposed subjects. In COVID-19 patients MVD was negatively correlated with the time from symptoms onset (coefficient -1·0, CI 95% -1·89 to -0·20) and positively correlated with disease severity (coefficient 22·0, CI 95% 5·2-38·9). INTERPRETATION: COVID-19 can affect the retina. Retinal veins diameter seems directly correlated with the disease severity. Its assessment could have possible applications in the management of COVID-19. FUNDING: None.

RESUMO

SARS-CoV-2 is causing an increasing number of deaths worldwide because no effective treatment is currently available. Remdesivir has shown in vitro activity against coronaviruses and is a possible antiviral treatment for SARS-CoV-2 infection. This prospective (compassionate), open-label study of remdesivir, which was conducted at Luigi Sacco Hospital, Milan, Italy, between February 23 and March 20, 2020, involved patients with SARS-CoV-2 pneumonia aged ≥18 years undergoing mechanical ventilation or with an oxygen saturation level of ≤94 % in air or a National Early Warning Score 2 of ≥4. The primary outcome was the change in clinical status based on a 7-category ordinal scale (1 = not hospitalised, resuming normal daily activities; 7 = deceased). The 35 patients enrolled from February 23 to March 20, 2020, included 18 in intensive care unit (ICU), and 17 in our infectious diseases ward (IDW). The 10-day course of remdesivir was completed by 22 patients (63 %) and discontinued by 13, of whom eight (22.8 %) discontinued because of adverse events. The median follow-up was 39 days (IQR 25-44). At day 28, 14 (82.3 %) patients from IDW were discharged, two were still hospitalized and one died (5.9 %), whereas in ICU 6 (33.3 %) were discharged, 8 (44.4 %) patients died, three (16.7 %) were still mechanically ventilated and one (5.6 %) was improved but still hospitalized. Hypertransaminasemia and acute kidney injury were the most frequent severe adverse events observed (42.8 % and 22.8 % of the cases, respectively). Our data suggest that remdesivir can benefit patients with SARS-CoV-2 pneumonia hospitalised outside ICU where clinical outcome was better and adverse events are less frequently observed. Ongoing randomised controlled trials will clarify its real efficacy and safety, who to treat, and when.

RESUMO

Introduction: Ritonavir and cobicistat are pharmacoenhancers used to improve the disposition of other HIV antiretrovirals. These drugs are, however, characterized by important pharmacokinetic differences.Areas covered: Here, the authors firstly update the available information on the pharmacokinetics of ritonavir and cobicistat. Subsequently, the review focuses on the description of drug-drug interactions (DDIs) involving cobicistat and comedications that might beneficiate from a shift-back to ritonavir. A MEDLINE Pubmed search for articles published from January 1995 to April 2019 was completed matching the term ritonavir or cobicistat with pharmacokinetics, DDIs, and pharmacology. Moreover, additional studies were identified from the reference list of retrieved articles.Expert opinion: Despite more than 20 years after its introduction on the market, ritonavir still represents a valid option for the treatment of selected HIV-infected patients. The large-scale switch to cobicistat may result in some unexpected DDIs not previously reported for ritonavir. Besides the issue of DDIs, additional advantage of ritonavir over cobicistat is its use in pregnancy, and its availability as single component of pharmaceutical formulations allowing the fine-tuning of antiretroviral regimens in patients with heavy polypharmacy when other unboosted-based therapeutic options cannot be used.

RESUMO

The use of procalcitonin (PCT) as a tool to assist clinicians in using antibiotics in intensive care patients has been postulated. Here we evaluate the efficacy of procalcitonin determination in helping clinicians in the decision to start or discontinue an antibiotic treatment in patients admitted to infectious disease wards. A retrospective observational single centre study was conducted in two infectious disease wards. Descriptive and inferential statistical analysis was carried out and receiver operating characteristic curves and area under the curve (AUC) were used to assess the accuracy of PCT and C-reactive protein (CRP) in separating patients undergoing antibiotic treatment or otherwise. In all, 164 patients were analysed of whom 99 (60.4%) were not on antibiotic treatment at the time of PCT determination, whereas 65 (39.6%) took antibiotics. Regarding the accuracy of PCT and CRP in determining a subsequent antibiotic prescription in patients without an ongoing antibiotic treatment, no statistically significant difference between the two markers was detected [AUC, 0.75; confidence interval (CI) 95%: 0.66-0.84; vs 0.69; CI 95%: 0.59-0.79 for PCT and CRP, respectively; p=0.32]. Conversely, in patients with an ongoing antibiotic treatment a statistically significant difference between PCT and CRP AUC in their ability to determine an antibiotic interruption was observed [0.77 (CI 95%: 0.65-0.89) vs 0.59 (CI 95%: 0.45-0.73) (p=0.03)]. PCT determination appeared to be more helpful than CRP in determining discontinuation of an antibiotic treatment in non-intensive care patients. However, PCT should supplement and not supplant a careful clinical evaluation.

RESUMO

OBJECTIVES: This retrospective study evaluates the effect of maraviroc, the first CCR5 receptor antagonist, on non-AIDS-related comorbidity incidence and its impact on inflammatory and lipid parameters. METHODS: Seventy-four HIV patients on maraviroc treatment were compared with 312 patients never exposed to maraviroc (matched for sex, age and CD4 nadir). RESULTS: At baseline (T0), maraviroc patients presented a longer duration of HIV infection, a higher prevalence of comorbidities and a greater frequency of polypharmacy. Non-AIDS-defining disease incidence was lower in the maraviroc group than in the non-maraviroc group (without achieving statistical significance). Except triglycerides (TGL), which dropped only in the maraviroc group, inflammatory and immunological parameters did not significantly change in either group by the end of the study period (T3). At T3, high-sensitivity C-reactive protein (hsCRP) and high-density lipoprotein were inversely correlated in both groups (Spearman's rho: maraviroc -0.30, P = 0.05; non-maraviroc -0.23, P = 0.0003). Only in the non-maraviroc group was the positive correlation between hsCRP and lipids observed both at T0 (hsCRP/low-density lipoprotein (LDL) +0.17, P = 0.004; hsCRP/total cholesterol +0.20, P = 0.0007; hsCRP/TGL +0.12, P = 0.04) and T3 (hsCRP/LDL +0.26, P < 0.0001; hsCRP/total cholesterol +0.24, P = 0.0001; hsCRP/TGL +0.15, P = 0.02). These correlations were not found in the maraviroc group. A significant positive correlation was found at T0 and at T3 between hsCRP and D-dimer in both groups (maraviroc: T0 +0.46, P = 0.0007; T3 +0.41, P = 0.006; non-maraviroc: T0 +0.17, P = 0.02; T3: +0.17, P = 0.017). CONCLUSIONS: These data suggest a possible protective role of maraviroc in the incidence of non-AIDS-related comorbidities in a population with longer-lasting infection and allow us to hypothesize its role in the modulation of lipid-dependent inflammation.

RESUMO

INTRODUCTION: The GEMINI trials have recently shown that a two-drug regimen of dolutegravir plus lamivudine was non-inferior to a three-drug regimen in HIV-infected naïve patients. Accordingly, it is important that physicians be aware and confident about the drug-drug interactions (DDIs) involving dolutegravir, lamivudine, and other medications. Areas covered: Here, we firstly update the available information on the pharmacokinetic features of dolutegravir and lamivudine; subsequently, the articles mainly deals with the predictable DDIs for both antiretroviral drugs, attempting to underline their clinical implications. This review focuses on the DDIs of dolutegravir/lamivudine combined regimen and, therefore, does not provide an exhaustive list of all the potential DDIs involving the two single agents. A MEDLINE Pubmed search for articles published from January 2000 to December 2018 was completed matching the terms dolutegravir or lamivudine with pharmacokinetics, DDIs, and pharmacology. Moreover, additional studies were identified from the reference list of retrieved articles. Expert opinion: The antiretroviral dual regimen of dolutegravir and lamivudine represents an attractive therapeutic option for HIV in terms of DDIs. This is particularly relevant considering that the population with HIV is aging and is increasingly experience age-related comorbidities, increasing pill burden, polypharmacy and the risk of DDIs.

RESUMO

INTRODUCTION: Despite the potency of current antiretrovirals, some patients continue to struggle with the management of the treatment of HIV due to drug resistance-associated mutations. The underlying causes of these developments are usually drug adherence and drug availability as well as the economic affordability of those potent drugs in low to middle-income countries as well as in some industrialised countries. Viral replication, despite therapy, varies by region from 5 to 28. Non-adherence includes a variety of behaviours with different clinical implications. Addressing non-adherence and choosing new regimens based on a strategic vision may aid overall treatment strategies in the future. Areas covered: The authors review the literature derived from Embase, MEDLINE and the main international congresses on transmitted and selected drug resistance to HIV therapeutics. They also consider the pharmacological aspects of antiretroviral therapy including the genetic barrier, convenience, potency, drug-drug interactions and tolerability are discuss prospective randomized or observational clinical trials on salvage therapy. Expert opinion: Preventive intervention is the most efficient way to reduce the selection and transmission of drug-resistant mutations. While subjects with no current available options may benefit from new compounds (ibalizumab and fostemsavir), strategies should be implemented to spare as many patients as possible from drug resistance.

RESUMO

This study aims to describe and characterize incident HR-HPV infections and associated diseases in HIV-infected women. 805 HIV-infected women enrolled in the VALHIDATE Study were screened and followed-up for HPV by co-testing. Social, behavioral and health data were collected. HPV-DNA positive samples were typed using a commercial kit or RFLP analysis. Conventional Pap-smears were evaluated using the 2001 Bethesda System. The participants with abnormal cytological results were referred for colposcopy. 565 HIV-infected women (median age: 43 years) were analysed, 40.9% had >5 lifetime sexual partners, 77.2% contracted HIV through sexual intercourse, 93% were receiving antiretroviral treatment and 77.3% had undetectable HIV-RNA. The women underwent 1254 follow-ups (median follow-up: 33 months) for 1430.6 PersonYear-Follow-Up. 37.4% of baseline HPV-negative women acquired incident HPV-infections, 69.6% of which were HR-HPVs. HPV-53 was the most common HPV type detected (9.3%). 18.2% of women showed incident or progressive cytological abnormalities (7.8% ASC-US, 9.7% LSIL and 0.6% HSIL) and colposcopy revealed CIN2 (N = 2), CIN1 (N = 2) and VIN3 (N = 1). The preventable fraction of incident infections was 11.3%, 16.7%, and 35.2% for the 2v-4v-9v-HPV vaccines respectively (χ2 p < 0.0001). The overall burden of incident lesions attributable to the vaccine types were 9.1% for 2v-, 14.5% for 4v- and 30.9% for 9v-vaccine. High HPV incidence rates and high percentages of multiple HR-HPV infections were observed in a cohort of HIV-infected women receiving effective antiretroviral treatment. Primary prevention strategies based on the new 9v-HPV vaccine may help to prevent incident infections and disease progression in this cohort of women.

RESUMO

INTRODUCTION: Hepatitis C virus (HCV) infection is a major cause of chronic liver disease, with approximately 71 million chronically infected individuals worldwide. Treatment of chronic hepatitis C has considerably improved in the last few years thanks to the introduction of direct-acting antivirals able to achieve sustained virological response in more than 95% of patients. Successful anti-HCV treatment can halt liver disease progression and solve the HCV-related extra-hepatic manifestations, eventually reducing liver-related and overall mortality. Areas covered: With the aim to respond to unmet needs in patient's identification, universal access to antiviral therapy and treatment optimization in specific setting of HCV-infected patients, a group of Italian experts met in Stresa in May 2018. The summary of the considerations arising from this meeting and the final statements are reported in this paper. Expert commentary: All the advances on HCV cure may have a real clinical impact not only in individual patients but also at the social health level if they are applied to all infected patients, independently from the stage of liver disease. Further improvements are needed in order to attain HCV elimination, such as the development of an enhanced screening program working in parallel to the present treatment options.

RESUMO

: The widespread use of antiretroviral treatment results in a significant improvement in immunological condition of people living with HIV (PLWH) who nevertheless experience a significantly increased risk to develop non-Hodgkin lymphoma compared with the general population. Despite many literature observations regarding multiple myeloma in PLWH, a consensus on its relevance in HIV infection does not exist. A number of large population studies on multiple myeloma in PLWH gave contrasting results, fluctuating from increased standardized incidence ratios to the lack of observed cases of multiple myeloma. Use of antiretroviral treatment, in this context, seems to induce a slight reduction of standardized incidence ratio, although with a partial effect, especially in young patients. However, a high variability in clinical onset has been described in different reports: the only common feature of multiple myeloma in PLWH is an atypical presentation as compared with general population, with a worse prognosis in case of uncontrolled HIV infection. We identified three pathogenetic steps in the complex scenario of multiple myeloma in PLWH: first, antigenic trigger; second, persistent T cell deficiency/dysfunction; third, altered regulation of B cells. All these pathogenetic steps play a role in immunological dysregulation, leading to B cell abnormalities and hyperactivation and, finally, resulting in the development of lymphoid malignancies. HIV has a role in each one of these three steps, due to its ability to trigger and dysregulate immune system. We hypothesize that HIV could be closely implicated in the multiple myeloma development in PLWH by accelerating the carcinogenesis events in a complex and only partially understood early aging process.

RESUMO

INTRODUCTION: The HIV-infected population is aging and comorbidities and polypharmacological regimens are increasing. To reduce toxicity and drug burden researchers are evaluating the efficacy, safety and durability of dual therapies as a switch option in subjects who have achieved stable virologic suppression. Initially effective dual combinations relied on protease inhibitors but when dolutegravir, the first integrase inhibitor to display a high genetic barrier, became commercially available, many physicians began to use it in a variety of dual regimens, generating several observational cohorts. Areas covered: This review covers the most recent data from observational cohorts and randomized clinical trials concerning the switch to the dual combination of dolutegravir plus rilpivirine and the reasons that lead to consider this option. Also, viral failures, due to poor adherence or to other factors, and drug resistance are investigated. Articles which are searchable on MEDLINE/PubMed and from the main national/international congresses in the field of HIV therapy are reviewed. Expert opinion: The observation period for this regimen is getting longer and data showing its efficacy in maintaining HIV-1 RNA < 50 copies/mL are now consolidated. Metabolic data suggest some benefit in the lipid profile, improvement in bone mineral density and reduced bone reabsorption.
