RESUMO

OBJECTIVES: The purpose of this observational retrospective study was to evaluate, in patients with a severe acute respiratory syndrome coronavirus 2 infection, the association between the severity of coronavirus disease 2019 (COVID-19) respiratory illness and the risk of infected patients to develop obstructive sleep apnea (OSA). METHODS: Ninety-six patients with confirmed COVID-19 infection were enrolled in the study. The STOP-BANG questionnaire to investigate the risk of the OSA syndrome was filled in by the patients at admission. The enrolled patients were divided into 2 groups according to the respiratory disease: group 1 (72 patients), hospitalized patients undergoing conventional oxygen therapy; group 2 (24 patients), patients requiring enhanced respiratory support. STOP-BANG results of these 2 groups were compared to observe whether patients with high OSA risk more frequently presented a severe form of COVID-19. RESULTS: 41.6% of the patients in group 2 had a STOP-BANG score between 5 and 8 (high risk of having apnea); in contrast, 20.8% of the patients in group 1 had a STOP-BANG score between 5 and 8, with a statistically significant difference between the 2 groups (P = .05). A complementary trend was observed regarding the proportion of patients in the range 0 to 2, which classifies patients at a low risk of OSA (48.6% vs 20.8% for groups 1 and 2, P = .01). CONCLUSIONS: According to our data, the chances of having a severe case of COVID-19 should be considered in patients at high risk of OSA. CURRENT KNOWLEDGE/STUDY RATIONALE: Emerging research suggests that OSA could represent a potentially important risk factor for the severe forms of COVID-19. The purpose of this observational retrospective study was to evaluate the potential association between OSA and the severity of COVID-19 disease. STUDY IMPACT: According to our data, the likelihood of contracting a severe form of COVID-19 disease should be considered in patients at high risk of OSA.

RESUMO

BACKGROUND: Total HIV-DNA load in peripheral blood cell (PBMCs) reflects the global viral reservoir that seems not to be affected by antiretroviral treatment. However, some studies reported a different permeability of different drugs in cellular compartments. OBJECTIVE: To investigate the relation between the amount of total HIV-1 DNA and different treatment strategies. METHODS: Total HIV-1 DNA was quantified by real time PCR in PBMCs collected from 161 patients with long-term undetectable HIV-RNA receiving different therapy schedules (3-drug regimens or 2-drug regimen containing Raltegravir as integrase inhibitor). RESULTS: Overall, HIV patients who started therapy with a median pre-ART CD4+ cell count >400 cells/mm3 and HIV viral load of 3 log10 copies/ml, achieved a lower amount of HIV total DNA. No significant correlation was found in DNA size when patients were stratified on the basis of different therapeutic protocols. However, HIV DNA load analysis, when only performed in HIV patients with a median pre-ART CD4+ cell count >200 cells/mm3 and HIV viral load < 3 log10 copies/ml, showed a significative DNA decrease in Raltegravir treated group with respect to the NNRTIs-treated group. CONCLUSION: The data emphasize that HIV-DNA level represents a predictive factor in long-term suppressive therapy patients. In addition, the diminished reservoir, only observed in patients treated with the NRTI-sparing regimen RAL plus PI/r before immunological and virological derangement, suggests that latest generation drugs, such as integrase inhibitors, might represent an optimal chance in the management of HIV infection.

RESUMO

OBJECTIVES: An observational, prospective, cohort study was performed to compare efficacy and safety of a switch from ritonavir-boosted protease inhibitor (PI/r) to nevirapine or raltegravir with that of rosuvastatin addition to current antiretroviral therapy in HIV-infected patients with hyperlipidaemia. METHODS: All HIV-infected patients receiving a stable PI/r-based antiretroviral regimen, with persistently suppressed viremia, naïve to non-nucleoside analogues and to integrase strand transfer inhibitors, with mixed hyperlipidaemia, and who underwent a switch from PI/r to nevirapine (Group A) or raltegravir (Group B) or who started rosuvastatin at 10 mg daily (group C) with unchanged antiretroviral regimen were enrolled into the study. RESULTS: Overall, 136 patients were enrolled: 43 patients were included in the group A, 46 in the group B, and 47 in the group C. The mean age was 46.6 years, and 108 (79.4%) were males. After 48 weeks of follow-up, a significantly greater reduction in the mean low-density lipoprotein (LDL) cholesterol level was reported in group C (-28.2%) than in group A (-10.2%; p < .001) and B (-12.4%; p = .021), while a significantly greater reduction in the mean concentration of triglycerides was observed in group A (-31.2%) and B (-35.5%) than in group C (-11.9%; p = .034 and p = .004, respectively). The incidence of adverse events was <10% and comparable across the three groups. CONCLUSION: In HIV-positive subjects receiving a PI/r, the initiation of rosuvastatin treatment after 48 weeks yielded a greater decline in LDL cholesterol, while the switch from PI/r to nevirapine or raltegravir led to a greater decline in triglycerides.

RESUMO

BACKGROUND: The combination antiretroviral therapy (cART) has dramatically improved the life expectancy of patients with HIV infection, but may lead to several long-term metabolic abnormalities. However, data about the frequency of metabolic syndrome (MS) in HIV-infected people vary considerably across different observational studies. METHODS: The prevalence of MS among HIV-infected patients was evaluated by a cross-sectional study conducted among subjects naive to cART or receiving the first antiretroviral regimen and referring to our Clinics from January 2015 to December 2015. The diagnosis of MS was made based on the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), and International Diabetes Federation (IDF) criteria. RESULTS: The study recruited 586 patients: 98 naive to cART and 488 under the first antiretroviral treatment. The prevalence of MS, according to NCEP-ATP III criteria, was significantly higher among treated patients than among naive ones (20.9% vs. 7.1%; p = 0.014). The most frequently reported components of MS among treated patients were high triglycerides (44.3%), low high-density lipoprotein cholesterol (41.1%), and hypertension (19.7%). On multivariate analysis, long duration of HIV infection, low nadir of CD4 lymphocytes, high body mass index, current use of one protease inhibitor, and long duration of cART were significantly associated with a higher risk of MS, while current use of one integrase inhibitor was significantly associated with a lower risk of MS. CONCLUSIONS: The non-negligible prevalence of MS among HIV-infected patients under cART requires a careful and periodic monitoring of its components, with particular attention to dyslipidemia and hypertension.

RESUMO

Nucleoside reverse transcriptase inhibitor (NRTI)- and protease inhibitor (PI)-sparing antiretroviral regimens may be useful in selected human immune deficiency virus (HIV)-infected patients with resistance or intolerance to these drug classes. This was an observational prospective study of patients on suppressive antiretroviral therapy containing two NRTIs plus one ritonavir-boosted PI who switched to a dual regimen containing raltegravir plus etravirine. Patients were required not to have prior virological failure to raltegravir and to have efficacy of etravirine shown through the genotypic resistance assay in case of prior non-nucleoside reverse transcriptase inhibitor (NNRTI) virological failure. As a whole, 38 patients were enrolled. The mean duration of current regimen was 4.3 years, and the reason for simplification was toxicity in 29 patients and resistance to NRTIs in 9 patients. After switching, the percentage of patients with HIV RNA <20 copies/ml at week 48 was 81.6% in the intent-to-treat-exposed analysis. The switch led to a significant reduction in the mean serum triglyceride levels (-81.2 mg/dl), in the mean total cholesterol levels (-44.3 mg/dl), and in the prevalence of tubular proteinuria (-30.2%), with a significant increase in the mean phosphoremia (+0.52 mg/dl) and in both mean lumbar and femoral neck bone mineral density (+6.5% and +4.7%, respectively). Two patients (5.2%) had virological failure due to suboptimal adherence, and five subjects (13.1%) discontinued treatment due to adverse events. In our study, simplification to the dual-therapy raltegravir plus etravirine was associated with a good efficacy and tolerability, in addition to a favorable effect on kidney, bone, and serum lipids.

RESUMO

BACKGROUND: Several studies have shown a significant association between vitamin D deficiency and an increased risk of statin-related symptomatic myalgia in the general population, but there are no data among HIV-infected persons. METHODS: A retrospective, cohort study was conducted to assess the incidence of symptomatic myalgia and elevation in serum creatine kinase level among HIV-positive adults on combination antiretroviral therapy and treated with atorvastatin or rosuvastatin for at least 12 months between 2011 and 2015 in our outpatient unit. RESULTS: A total of 545 patients (mean age 53.4 years) were enrolled into the study. Atorvastatin was prescribed in 55.8% of patients and rosuvastatin in 44.2%. After a mean duration of statin therapy of 29 months, an isolated symptomatic myalgia was diagnosed in 42 patients (7.7%) and a myalgia associated with elevated creatine kinase level in 25 (4.6%). The mean concentration of 25-hydroxyvitamin D was significantly lower in patients with myalgia (19.4 ng/ml) and with creatine kinase elevation and myalgia (22.8 ng/ml) than in those without muscle toxicity (32.1 ng/ml; P = 0.017 and 0.024, respectively). In stratified multivariable-adjusted logistic regression models, there was a statistically significant association between vitamin D deficiency and occurrence of symptomatic myalgia (P = 0.009) or creatine kinase elevation and myalgia (P = 0.046). Other factors significantly associated with development of myalgia were duration of statin therapy more than 24 months, history of myalgia, and age older than 60 years. DISCUSSION: In our observational study, vitamin D deficiency was significantly associated with a statin-induced myalgia among HIV-infected patients on combination antiretroviral therapy, in conformity with data of the general population.

RESUMO

OBJECTIVES: Statins have shown anti-inflammatory and immune-modulatory properties in both general and HIV-infected population, but their effect on plasma D-dimer levels is controversial and it has not been investigated to date in HIV-positive patients. The aim of our study was to assess the effect of rosuvastatin on D-dimer and other serum inflammation markers among these subjects. METHODS: Prospective, cohort study of HIV-1-infected adult patients receiving a stable combination antiretroviral therapy (cART), who started a lipid-lowering therapy with rosuvastatin (10 mg daily) and were followed up for at least 12 months. The primary endpoint was the change at month 12 in the median plasma concentration of D-dimer. The secondary endpoints included the variation in median plasma levels of these inflammatory biomarkers: interleukin-8 (IL-8), interleukin-10 (IL-10), and interleukin-12 (IL-12). RESULTS: Sixty-two patients were enrolled in the study, and the endpoints were available for 54 subjects. After 12 months, a significant decrease in median plasma concentration of D-dimer was observed (-21.4%; interquartile range [IQR], -35.5; -4.2; p = .029). With regard to the inflammatory biomarkers, a significant decrease in median levels of IL-8 (-24.6%; IQR, -30.8; -1.8; p = .012) and IL-12 (-18.7%; IQR, -25.8; +2.5; p = .033) was also observed. Rosuvastatin led to a significant reduction in serum lipid values and showed a good tolerability profile. CONCLUSIONS: Our findings show that a 12-month treatment with rosuvastatin associated with an effective cART can significantly decrease the plasma levels of D-dimer, IL-8, and IL-12, and suggest a potential role for this statin to reduce activated coagulation and systemic inflammation among HIV-infected persons.

RESUMO

BACKGROUND: Nucleoside reverse transcriptase inhibitor (NRTI)-sparing antiretroviral therapies may be useful in HIV-infected patients with resistance or intolerance to this class. METHODS: We performed an observational study of patients on suppressive antiretroviral therapy containing two NRTIs plus one ritonavir-boosted protease inhibitor who switched to a dual regimen containing raltegravir (400 mg twice daily) and darunavir/ritonavir (800/100 mg once daily) and were followed-up for 48 weeks. RESULTS: As a whole, 82 patients were enrolled. Mean duration of current regimen was 4.6 years and mean duration of plasma HIV RNA < 50 copies/mL before the switch was 46.2 months. Reason for simplification was toxicity in 76 patients and resistance to NRTIs in 13. After switching, the percentage of patients with HIV RNA < 50 copies/mL at week 48 was 92.7% in the intent-to-treat-exposed analysis and 97.6% in the per-protocol analysis. The switch led to a significant reduction in the mean triglyceride value (-85.2 mg/dL), in the prevalence of tubular proteinuria (-56%) and in the mean level of interleukin-6 (-0.94 pg/mL), with a significant increase in the mean phosphoremia (+0.58 mg/dL). Mean trough concentrations of both raltegravir and darunavir were within the therapeutic range. Two patients (2.4%) had virological failure due to suboptimal adherence and 4 subjects (4.9%) discontinued treatment due to adverse events, but no patients experienced Grade 3 or 4 adverse events. CONCLUSION: In our study, simplification to a dual therapy containing raltegravir plus darunavir/ritonavir after 48 weeks maintained viral suppression in more than 90% of patients and showed a good tolerability with a favourable effect on proteinuria, ipophosphoremia, and lipid metabolism.

RESUMO

BACKGROUND: The antiretroviral regimens including tenofovir and a ritonavir-boosted protease inhibitor (r/PI) have been associated with a reduced bone mineral density (BMD), increased bone turnover markers and renal tubular dysfunction. METHODS: An observational, prospective study was performed including HIV-1-infected, virologically suppressed patients treated with tenofovir/emtricitabine plus an r/PI for at least 12 months who switched to raltegravir plus nevirapine. The primary end point was changes after 48 weeks in estimated glomerular filtration rate (eGFR), prevalence of tubular dysfunction, BMD and concentration of two serum markers of bone turnover: collagen type-1 cross-linked C-telopeptide (CTX) and bone-specific alkaline phosphatase (BAP). RESULTS: A total of 46 patients were enrolled: 78% were male, 96% were Caucasian, the mean age was 45 years and the mean CD4(+) T-lymphocyte count was 681 cells/mm(3). A renal impairment was present in 72% of patients and was the main reason for the switch. After 48 weeks, prevalence of proximal tubular dysfunction decreased significantly (-72%; P<0.001), whereas the mean value of eGFR did not change significantly. At the same time, after 48 weeks a significant increase in both lumbar spine and total hip BMD, T-score and Z-score was reported (+11.5% in lumbar spine T-score; P<0.001), and there was a significant reduction in both CTX and BAP mean serum concentrations (-15% and -13%, respectively; P<0.001). Two (4.3%) patients had virological failure due to suboptimal adherence and one (2.2%) subject discontinued treatment due to a skin rash. CONCLUSIONS: Switching virologically suppressed patients from tenofovir/emtricitabine plus one r/PI to raltegravir plus nevirapine after 48 weeks significantly improved proximal tubular function, increased BMD and reduced serum markers of bone turnover.

RESUMO

BACKGROUND: The association between abacavir use and increased risk of myocardial infarction has been heavily debated, but cohort studies and randomized trials have provided conflicting results. Aim of our study is to compare the effect of abacavir and tenofovir on the inflammation and endothelial activation markers. METHODS: We performed an observational study of HIV-infected naïve patients starting tenofovir/emtricitabine (group A) or abacavir/lamivudine (group B) plus efavirenz. In the present analysis, we measured serum levels of high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), soluble vascular adhesion molecule-1 (VCAM-1), soluble intercellular adhesion molecule-1 (ICAM-1), E-selectin and P-selectin at baseline and during a 48-week follow-up. RESULTS: As a whole, 118 patients (93 males; mean age ± SD of 42.8 ± 10.1 years) were enrolled: 61 in group A and 57 in group B. In group A at weeks 24 and 48 the mean concentrations of IL-6, TNF-α, ICAM-1, VCAM-1, E-selectin and Pselectin decreased significantly in comparison with respective baseline values. In group B at week 24 a significant increase in mean values of these markers was reported in comparison with group A, but after 48 weeks they significantly decreased in group B too and no significant differences between groups A and B were found. CONCLUSION: In our study, naïve patients starting tenofovir/emtricitabine or abacavir/lamivudine plus efavirenz showed after 48 weeks a significant and comparable decrease in serum concentrations of IL-6, TNF-α, ICAM-1, VCAM-1, Eselectin and P-selectin, while the mean level of hs-CRP did not change significantly in any group.

RESUMO

BACKGROUND: The objective of the study was to assess plasma concentrations of efavirenz, darunavir/ritonavir and raltegravir in patients with human immunodeficiency virus-hepatitis C virus (HIV-HCV)-coinfection without liver cirrhosis. METHODS: In this observational, open-label study, adult HIV-infected outpatients treated with tenofovir/emtricitabine plus efavirenz (600 mg daily), darunavir/ritonavir (800/100 mg daily) or raltegravir (400 mg twice daily) for at least 4 weeks were asked to participate. Subjects with liver cirrhosis were excluded. The trough concentration (C trough) of darunavir/ritonavir and raltegravir and the mid-dose concentration (C12h) of efavirenz were assessed at steady state by a validated high-performance liquid chromatography (HPLC)-tandem mass spectrometry method. RESULTS: A total of 96 HIV-positive patients were enrolled into the study. Thirty-four patients were treated with efavirenz, 33 with darunavir/ritonavir and 29 with raltegravir. The geometric mean plasma C trough [coefficient of variation (%)] of darunavir was comparable between HIV+/HCV+ and HIV+/HCV- subjects: 2644 ng/ml (155%) and 2491 ng/ml (139%), respectively (geometric mean ratio (GMR) = 0.81; 95% confidence interval (CI) = 0.79-1.56; p = 0.69). These values were comparable for raltegravir: 108 ng/ml (149%) in the HIV+/HCV+ group and 96 ng/ml (161%) in the HIV+/HCV- group (GMR = 0.84; 95% CI = 0.61-1.44; p = 0.72). On the contrary, the geometric mean plasma C12h of efavirenz was significantly higher among the 15 HIV+/HCV+ patients (1915 ng/ml, 159%) than among the 19 HIV+/HCV- patients (1505 ng/ml, 167%; GMR = 1.41; 95% CI = 1.19-1.71; p = 0.009). CONCLUSIONS: The mean plasma concentration of efavirenz was significantly higher in HCV-positive than in HCV-negative patients without liver cirrhosis, while the mean plasma levels of darunavir/ritonavir and raltegravir were comparable in both groups.

RESUMO

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.

RESUMO

BACKGROUND: Renal disease is an increasingly recognized noninfectious comorbidity associated with human immunodeficiency virus (HIV) infection. METHODS: Our retrospective, cross-sectional study evaluated prevalence of nephropathy among HIV-infected patients followed up in our outpatient clinic during the year 2011. Renal dysfunction and chronic kidney disease (CKD) were defined as estimated glomerular filtration rate (eGFR) <90 ml/min per 1.73 m(2) and as renal damage or eGFR <60 ml/min per 1.73 m(2) over a 3-month or greater period, respectively. RESULTS: We enrolled 894 HIV-infected patients with a mean age of 44.2 years and a mean current CD4 lymphocyte count of 508 cells/mm(3). The prevalence of renal dysfunction and CKD was 27.4 and 21.3 %, respectively. Older age, male gender, hypertension, diabetes, proteinuria, hypertriglyceridemia, lower nadir CD4 cell count, current use of tenofovir or tenofovir plus a ritonavir-boosted protease inhibitor were independently associated with renal dysfunction. CONCLUSION: Renal dysfunction is a frequent comorbidity among HIV-infected persons and requires a careful clinical and laboratory monitoring of renal function.

RESUMO

OBJECTIVES: We performed a retrospective cohort study of HIV-infected antiretroviral-naïve patients starting a first antiretroviral therapy with tenofovir/emtricitabine plus efavirenz (EFV), atazanavir/ritonavir (ATV/r), or lopinavir/ritonavir (LPV/r). METHODS: The incidence of renal impairment or proximal tubular dysfunction was evaluated during a 12-month follow-up. Renal impairment was diagnosed by a reduced estimated glomerular filtration rate (eGFR) calculated using the Modification of Diet in Renal Disease (MDRD) formula, and tubular dysfunction was diagnosed when ≥ 2 among proteinuria, glucosuria, hypouricaemia, hypophosphataemia, and hypokalaemia, were identified. RESULTS: A total of 235 patients were enrolled: 82 taking EFV, 78 ATV/r, and 75 LPV/r. The mean decline in eGFR after the 12-month follow-up was significantly greater in subjects treated with ATV/r (-10.4 ml/min/1.73 m(2)) than in those receiving EFV (- 5.1; p = 0.002) or LPV/r (-4.8; p = 0.003). Similarly, a significantly higher incidence of proximal tubulopathy was observed among ATV/r-treated patients (14.1%) compared with patients receiving EFV (4.9%) or LPV/r (5.3%). CONCLUSIONS: In our retrospective study, naïve patients receiving tenofovir/emtricitabine and ATV/r for 12 months showed a significantly higher decline in eGFR and a significantly higher incidence of proximal tubulopathy than those receiving tenofovir/emtricitabine plus EFV or LPV/r, even though clinically evident renal toxicity associated with tenofovir-based treatment is a very uncommon event.

RESUMO

Recent studies have shown that rosuvastatin significantly decreases serum levels of inflammatory biomarkers and slows progression of carotid atherosclerosis in the general population. However, there are no data about its effect on progression of atherosclerosis in HIV-infected patients. Adult patients with HIV infection, on stable antiretroviral therapy, with asymptomatic carotid atherosclerosis and hypercholesterolemia, who started a rosuvastatin treatment at 10 mg daily during the period 2007-2009 were enrolled and followed-up for 24 months. Thirty-six patients (30 males) were enrolled, with a mean age of 49 years, a mean duration of current antiretroviral therapy of 38 months, and a mean 10-year risk of myocardial infarction of 18.5%. Rosuvastatin led to a significant decrease in mean values of intima-media thickness in all extracranial carotid arteries, with the greatest magnitude observed in carotid bifurcations (a mean decrease of 18.7% in the right artery and of 21.4% in the left artery) and in internal carotid arteries (a mean decrease of 23.7% in the right artery and of 25.6% in the left artery). Moreover, there was a significant reduction in mean levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides versus respective baseline values associated with a significantly decreased mean cardiovascular risk. The treatment with rosuvastatin was well tolerated, and serious adverse events were not reported. A 24-month treatment with rosuvastatin in HIV-infected patients on highly active antiretroviral therapy (HAART) with subclinical atherosclerosis and a moderate cardiovascular risk seems to promote significantly favorable changes in carotid atherosclerosis, associated with a favorable effect on serum lipid levels and a good tolerability profile.
