In an ongoing Mediterranean cohort, we compared age-related conditions between 208 HIV-infected persons and 104 matched controls. ≥3 comorbidities were found in 31.0% of HIV-infected patients and 8.7% of controls. Conditions significantly more frequent among the HIV-infected population were: lipid abnormalities, cancer, osteopenia/osteoporosis, liver disease, sexual dysfunction, hearing deficit, sleep disorders, falls, cognitive complaints, being single, living alone, and being elderly at risk. HIV-infected patients aged >70 years had a significantly higher number of cardiovascular risk factors (CVRF) and comorbidities than controls. HIV-infected persons who had never smoked had a higher prevalence of CVRFs, ≥3 comorbidities, liver disease, cancer, and cognitive complaints compared to controls. Factors associated with frailty were being a man who has sex with men, ≥3 CVRFs, nadir CD470 years. The multidisciplinary assessment also revealed concerning findings in social, cognitive, and functional variables among HIV-infected individuals, with a higher prevalence of elderly at risk than among controls.

Background:HIV infection is an increasingly complex chronic disease associated with numerous medical, psychological, and social problems. The life expectancy of affected patients has increased considerably. Medical apps could also play a role in prevention and management of comorbid conditions in the HIV-infected population. Objectives:To determine the usefulness of an app designed specifically for HIV-infected patients aged 60 years or older and to assess changes in patient satisfaction, adherence to treatment, and quality of health care. Methods:A randomized clinical trial was conducted, including 100 patients (50 per group): (1) an experimental group comprising patients using the app + routine medical care (app group) and (2) with routine medical care (control group). The usability of the app and patient satisfaction were evaluated in the app group at week 48. Quality of life, adherence to treatment, and clinical parameters were compared between both groups at 48 weeks, as well as the number of face-to-face visits. Results:We found that 52.2% and 73.8% of patients in the app group used the app at weeks 24 and 48, respectively. Patients used the app for a mean of 23.7 (+/- 2.84) days over the 48 weeks. The most visited screens were health counseling and medical records (24.8% and 22.2%, respectively). At week 48, 85.2% of patients thought that the app was useful and 91.4% would recommend the app to friends or relatives. The app was well valued by participants (4.79 [+/- 0.21] of 5.00) and 64.6% thought that the app improved their health care.

To determine the prevalence of potential prescribing issues (PPI) in HIV-infected subjects aged ≥65 years according to the Beers and STOPP/START criteria and antiretroviral drug-drug interactions (Liverpool website). Secondary objectives were to assess the concordance between Beers and STOPP/START criteria in our population, and to identify the drugs most frequently involved in PPI.Cross-sectional cohort study based on a systematic review of the electronic drug prescriptions confirmed by an interview of 91 HIV-infected patients aged ≥65 years. Discrepancies between prescription criteria were assessed using crosstabs and compared using the χThe mean age was 72.1 (5.6) years, 75.8% had ≥3 comorbidities and 59.3% polypharmacy. PPI were identified in 87.9%: 71.4% by STOPP/START and 45.1% by Beers. Comparing both criteria, 56.9% of PPI by STOPP/START were detected by Beers, while 92.5% of those detected by the Beers criteria were detected by STOPP/START (P.001). Amber/red flag interactions between antiretrovirals and comedications were found in 45.1%: 3 severe (red) in 2 patients (2.2%). The most frequent drugs involved in PPI were benzodiazepines (30%). Cobicistat was the drug most frequently involved in potential interactions (42.2%).The prevalence of PPI among older HIV-infected persons gives cause for concern, as it is almost 90%. Optimization strategies, including a critical review of the treatment plan, should be implemented in clinical routine by a multidisciplinary team, in particular in patients with multiple comorbidities and polypharmacy. The STOPP/START criteria seem to detect more PPI, mainly for European populations.

BACKGROUND Information and communication technologies are key to improving health and ensuring a quality, modern, and sustainable health system. They could prove particularly useful in the care of patients with chronic conditions such as diabetes, obesity, cardiovascular disease, and HIV infection. It could also play a role in the prevention of comorbid conditions OBJECTIVE To determine the usefulness of an app designed specifically for HIV-infected patients aged 60 years or older by evaluating its usability. To assess changes in patient satisfaction with the app, adherence to treatment, and quality of health care in HIV-infected patients who use the app METHODS Randomized clinical trial, including 2 groups: 1) an experimental group comprising patients using the app + routine medical care and 2) a control group. The usability of the app and patient satisfaction were evaluated in the app group at weeks 24 and 48. Quality of life, adherence to treatment, and clinical parameters were compared in both groups at 48 weeks RESULTS The study population comprised 100 patients (50 per group). Men accounted for 73%, median age was 65 (IQR, 63-69) years, 46% were men who have sex with men, and the median time with HIV infection was 21 (IQR 16-25) years. We found that 52.2% and 73.8% of patients in the app group used the app at weeks 24 and 48. Patients visited the app on a mean of 23.7 (±2.84) days over the 48 weeks. The total number of sessions was 6,177, and the mean session time was 6 minutes and 51 (±34.72) seconds.The most visualized screens were health counseling and medical records (laboratory results) (24.8% and 22.2%, respectively). Patients aged 60 to 65 years were the age group that most actively used the app compared with those aged over 65 years (P=.029). At week 48, 85.2% of patients thought that the app was useful, and 91.4% would recommend the app to friends or relatives. The app was well valued by participants (4.79 [±0.21] out of 5.00), and 64.6% thought that the app improved their health care. The number of face-to-face visits to the HIV unit during the study was 4.29 (±1.43) for the app group and 5.33 (±1.72) for the control group (P=.03). There were no significant differences in patient quality of life, adherence, or inter- and intragroup clinical parameters. CONCLUSIONS Our study shows the low usability of the app in HIV-infected patients, mainly among those aged over 65 years. Patients reported that the main use for the app was to receive health counseling and medical data (laboratory results). It is therefore necessary to promote knowledge of the app and motivate patients in this age group to use it.

Human immunodeficiency virus (HIV)-1 infection causes severe gut and systemic immune damage, but its effects on the gut microbiome remain unclear. Previous shotgun metagenomic studies in HIV-negative subjects linked low-microbial gene counts (LGC) to gut dysbiosis in diseases featuring intestinal inflammation. Using a similar approach in 156 subjects with different HIV-1 phenotypes, we found a strong, independent, dose-effect association between nadir CD4+ T-cell counts and LGC. As in other diseases involving intestinal inflammation, the gut microbiomes of subjects with LGC were enriched in gram-negative Bacteroides, acetogenic bacteria and Proteobacteria, which are able to metabolize reactive oxygen and nitrogen species; and were depleted in oxygen-sensitive methanogenic archaea and sulfate-reducing bacteria. Interestingly, subjects with LGC also showed increased butyrate levels in direct fecal measurements, consistent with enrichment in Roseburia intestinalis despite reductions in other butyrate producers. The microbiomes of subjects with LGC were also enriched in bacterial virulence factors, as well as in genes associated with beta-lactam, lincosamide, tetracycline, and macrolide resistance. Thus, low nadir CD4+ T-cell counts, rather than HIV-1 serostatus per se, predict the presence of gut dysbiosis in HIV-1 infected subjects. Such dysbiosis does not display obvious HIV-specific features; instead, it shares many similarities with other diseases featuring gut inflammation.

Long-term results ( > 5 years) for synthetic substances used to repair facial lipoatrophy have not been published. We performed a cross-sectional study to evaluate the 10-year safety of polyacrylamide hydrogel (Aquamid) among the 751 patients from our unit who received facial infiltrations at least 10 years ago. Epidemiological and clinical data such as complications and patient satisfaction were collected. We also identified those patients who presented a facial infection at any time after infiltration. A total of 104 patients had received Aquamid at least 10 years ago. Before infiltrations, 24.0%, 41.3%, and 34.7% presented very severe, severe, and moderate facial lipoatrophy, respectively. After a mean (SD) of 10.3 (0.5) years since the infiltrations, 19.2%, 47.7%, and 31.7% of patients reported moderate, mild, and no signs of facial lipoatrophy. The values reported by physicians for the same categories were 1.9%, 10.6%, and 87.5%. Indurations were detected in 6.7% of patients and nodules in 3.8%. Five patients (4.8%) had a local infection. A further 15 patients with a shorter follow-up (less than 10 years) presented local infections (overall incidence considering the 751 patients who received infiltrations of Aquamid, 2.7%); the product had to be withdrawn in three cases. The majority of patients were highly satisfied (74.8%) or satisfied (23.4%) with the cosmetic results; among patients with severe or very severe lipoatrophy at baseline, 31.4% were satisfied and 65.7% were highly satisfied. Infiltrations with polyacrylamide hydrogel (Aquamid) are a safe strategy for the treatment of facial lipoatrophy in the long term. The rate of severe complications was low, and patient satisfaction with the cosmetic results was high. However, facial infections may appear in the long term. Therefore, HIV-infected patients who received synthetic substances should be carefully monitored over time.

Objectives Given the need for easily managed treatment of osteoporosis in HIV-infected patients, we evaluated the efficacy and tolerability of two doses of zoledronate, by comparing three groups of patients: those with annual administration, those with biennial administration (one dose in 2 years) and a control group with no administration of zoledronate. Methods We randomized (2:1) 31 patients on antiretroviral therapy with low bone mineral density (BMD) to zoledronate (5 mg administered intravenously; 21 patients) plus diet counselling and to a control group (diet counselling; 10 patients). At week 48, patients treated with zoledronate were randomized again to receive a second dose (two-dose group; n = 12) or to continue with diet counselling only (single-dose group; n = 9). Changes in lumbar spine and hip BMD and bone turnover markers were compared. Results The median percentage change from baseline to week 96 in L1−L4 BMD was −1.74% [interquartile range (IQR) −2.56, 3.60%], 7.90% (IQR 4.20, 16.57%) and 5.22% (IQR 2.02, 7.28%) in the control, two-dose and single-dose groups, respectively (P

Background Osteoporotic fractures still remain very infrequent and physicians rarely evaluate bone health. We wanted to assess the magnitude of this problem in the near future by determining the risk and likelihood of progression to osteoporosis. Methods We estimated the risk of progression to osteopenia/osteoporosis among HIV-infected patients with at least 2 DXA scans (3726 scans from 875 patients). Time-non-homogeneous bidirectional multistate models based on three states (normal bone mineral density, osteopenia and osteoporosis) were used to model the progression of bone mineral density as a function of age and to study the association between the risk of bone loss and antiretroviral use. Results The HRs associated with age (>45 versus ≤45 years) were: (i) from normal bone mineral density to osteopenia, 0.71 (95% CI 0.45-1.11) for men and 1.06 (95% CI 0.55-2.05) for women; and (ii) from osteopenia to osteoporosis, 0.83 (95% CI 0.51-1.35) for men and 0.99 (95% CI 0.38-2.56) for women. The transition probabilities from osteopenia to osteoporosis over 10 years among men aged 30 and 50 years were 14.9% (95% CI 10.5%-20.4%) and 19% (95% CI 14.3%-24.3%), respectively; and for women, 6.9% (95% CI 3.1%-14.4%) and 30.1% (95% CI 19.8%-41.8%), respectively. An increased osteoporosis risk was observed for PIs and PIs + tenofovir disoproxil fumarate; darunavir was associated with a higher risk of osteoporosis among men (HR 3.9; 95% CI 2-7.5) and women (HR 4.5; 95% CI 1.4-14.7); and atazanavir was associated with a higher risk of osteoporosis among women (HR 4.2; 95% CI 1.3-14). Conclusions Our results highlight the importance of monitoring bone mineral density given the high probability of progression to osteopenia/osteoporosis, especially in women. In the future, changes in antiretrovirals other than tenofovir, such as PIs, should be recommended to reduce the risk of fracture.

DNA sequencing technologies have revolutionized microbiome studies. In this work we analyze microbiome data from an HIV study focused on the characterization of microbiome composition in HIV-1 infected patients. A 155 cohort of HIV infected and non-infected individuals is analyzed to characterize dietary and gut microbiome association in this group of patients. A penalized Dirichlet Multinomial regression model has been considered. The assumed underlying Dirichlet distribution in this modelization provides additional flexibility to the multinomial model which results in a better fit of the typically overdispersed microbiome data.

Background: Hypovitaminosis D is highly prevalent among HIV-infected patients. Since hypovitaminosis D is a secondary cause of low bone mineral density (BMD), we assessed its prevalence and associated factors in HIV-infected patients with osteopenia/osteoporosis, compared with HIV-infected patients with normal BMD. Materials & methods: Serum 25-hydroxy vitamin D (25[OH]D) concentration were collected from 149 HIV-infected subjects with low BMD and 36 with normal BMD from April to October, 2010. Regression analyses were fitted to predict the probability of hypovitaminosis D in all patients. Results: Of the 149 patients with low BMD (51.8 ± 8 years old, 76.5% men), 83% had vitamin D insufficiency (

We assessed the progress of renal damage after discontinuation of tenofovir (TDF) in patients who started therapy with normal renal parameters. Normal local reference values were as follows: estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease equation (MDRD), ⩾60mL/min/1.73m(2); creatinine, ⩽1.20mg/dL; serum phosphate: ⩾2.69mg/dL; proteinuria:30mg/dL, and glycosuria:20mg/dL in nondiabetic patients. A logistic regression analysis was used to evaluate factors related to normalization of renal function. We included 183 patients; 85% were male, and median (IQR) age was 44 (40-50)years. Time on TDF was 39 (22-63)months. After 22 (13-49.5)months from TDF discontinuation, renal parameters returned to normal values in 59% of patients, improved (without reaching normal values) in 9.8%, and did not improve in 31%. Median time until normalization was 4 (2-15.75)months, and time to maximum improvement in patients whose values did not return to normal was 14 (8.75-27.75)months. Follow-up was12months in 30% of the patients who did not improve. The only factors significantly associated with normalization of renal parameters were nadir CD4 T-cell count (p=0.034; OR=1.002, per 1 cell of increase) and CD4 T-cell count at the end of therapy with TDF (p=0.030; OR=1.033, per 1 cell of increase). Reversibility of renal damage was prompt and complete in 59% of patients receiving TDF-containing regimens and was associated with a higher nadir and current CD4+ T-cell count, suggesting a role of preserved cellular immunity in renal recovery in this population.

Background. Nucleoside reverse-transcriptase inhibitor (NRTI)-related mitochondrial toxicity has been suggested as a key factor in the induction of antiretroviral-related lipoatrophy. This study aimed to evaluate in vivo the effects of NRTI withdrawal on mitochondrial parameters and body fat distribution. Methods. A multicenter, prospective, randomized trial assessed the efficacy and tolerability of switching to lopinavir-ritonavir plus nevirapine (nevirapine group; n = 34), compared with lopinavir-ritonavir plus 2 NRTIs (control group; n = 33) in a group of human immunodeficiency virus-infected adults with virological suppression. A subset of 35 individuals (20 from the nevirapine group and 15 from the control group) were evaluated for changes in the mitochondrial DNA (mtDNA) to nuclear DNA ratio and cytochrome c oxidase (COX) activity after NRTI withdrawal. Dual-energy X-ray absorptiometry (DEXA) scans were used to objectively quantify fat redistribution over time. Results. The nevirapine group experienced a progressive increase in mtDNA content (a 40% increase at week 48; P = .039 for comparison between groups) and in the COX activity (26% and 32% at weeks 24 and 48, respectively; P = .01 and P = .09 for comparison between groups, respectively). There were no statistically significant between-group differences in DEXA scans at week 48, although a higher fat increase in extremities was observed in the nevirapine group. No virologic failures occurred in either treatment arm. Conclusions. Switching to a nucleoside-sparing regimen of nevirapine and lopinavir-ritonavir maintained full antiviral efficacy and led to an improvement in mitochondrial parameters, which suggests a reversion of nucleoside-associated mitochondrial toxicity. Although DEXA scans performed during the study only revealed slight changes in fat redistribution, a longer follow-up period may show a positive correlation between reduced mitochondrial toxicity and a clinical improvement of lipodystrophy.

Although some clinical trials have studied the impact of treatments on bone mineral density (BMD), scarce data are available about the impact of protease inhibitor (PI) monotherapies on BMD. The aim of this study was to evaluate changes in BMD in patients after one, two, or three years of a PI monotherapy. This study included 46 HIV-infected patients who switched from a conventional triple antiretroviral strategy to a monotherapy with lopinavir/ritonavir (LPV/r) or darunavir/ritonavir (DRV/r) for one (one-year group, n=16), two (two-year group, n=20), and three (three-year group, n=10) years. BMD was assessed by dual-energy X-ray absorptiometry (DXA). The median percentage of change in total femur BMD was 0.20% after one, 0.79% after two, and -0.31% after three years. The change in lumbar spine was -0.08%, -0.14%, and 0.50% % after the same years. No significant differences were found when patients were classified regarding the type of PI and whether or not had previously received PI or tenofovir. However, patients who interrupted tenofovir or those who started with DRV/r had a higher BMD increment. Patients who had taken non-nucleoside reverse transcriptase inhibitors previously decreased BMD when started PIs. Monotherapy treatment with ritonavir-boosted protease inhibitors (both LPV/r and DRV/r) during one, two, or three years leads to the stabilization of BMD in HIV-infected patients with long-term virological suppression. Larger studies are necessary to compare the effect of starting or withdrawing PIs on BMD.

Background. It is unknown if tenofovir disoproxil fumarate (TDF), which is often coformulated with the lipidneutral emtricitabine (FTC), has a lipid-lowering effect. Methods. We performed a randomized, crossover, double-blind, placebo-controlled clinical trial on human immunodeficiency virus type 1 (HIV-1)–infected subjects with HIV-1 RNA < 50 copies/mL during ≥6 months on stable darunavir/ritonavir (800/100 mg once daily) or lopinavir/ritonavir (400/100 mg twice daily) monotherapy, fasting total cholesterol (TC) ≥200 mg/dL or low-density lipoprotein cholesterol (LDL-c) ≥130 mg/dL, and no lipid-lowering drugs. In arm 1, TDF/FTC was added for 12 weeks, followed by 12 weeks of placebo (washout) and 12 additional weeks of placebo ( placebo period). Subjects in arm 2 added placebo for 12 weeks ( placebo period) followed by TDF/FTC for 12 weeks and placebo for 12 additional weeks (washout). The primary endpoint was change in median fasting TC levels. Results. Of 46 subjects enrolled, 56% received darunavir/ritonavir and 44% lopinavir/ritonavir. Exposure to TDF/FTC reduced TC from 234 to 205 mg/dL (P < .001), LDL-c from 155 to 128 mg/dL (P < .001), and high-density lipoprotein cholesterol (HDL-c) from 50.3 to 44.5 mg/dL (P < .001). It also decreased the proportion of subjects with fasting TC ≥200 mg/dL from 86.7% to 56.8% (P = .001), and LDL-c ≥130 mg/dL from 87.8% to 43.9% (P < .001). After 12 weeks, TDF/FTC exposure was associated with lower TC and LDL-c levels than placebo (P = .001 and P = .002, respectively). The TC/HDL-c ratio and triglyceride levels did not change with TDF/FTC exposure. Conclusions. Coformulated TDF/FTC has an intrinsic lipid-lowering effect, likely attributable to TDF.

Lipodystrophy is one of the foremost concerns among the HIV-positive population, and is often associated with psychosocial disorders. We evaluated the clinical efficacy of facial infiltrations with autologous fat, polylactic acid, and polyacrylamide gel using clinical inspection and facial photographs (ordinal scale). Additionally, we assessed the safety of the infiltration techniques and determined changes in patient satisfaction, emotional status, and quality of life. Evaluations were made at 48- and 96-week follow-up visits. This paper presents the 48- week follow-up results. The current analysis includes 138 patients: 8, 25, and 105 in the fat, polylactic acid, and polyacrylamide gel groups, respectively. At baseline, almost 50% of the patients (67/138) presented grades 3 and 4 lipoatrophy, but at week 48 only 7.5% (7/93) remained in these advanced grades (no patients from the polyacrylamide group). A new round of infiltrations at week 48 was necessary in 35% (33/93) of patients (88%, 84%, and 8% in the fat, polylactic, and polyacrylamide groups, respectively). No serious adverse events were detected with any of the substances. Patient satisfaction and quality of life improved significantly in all three groups. Infiltrations with autologous fat, polylactic acid, or polyacrylamide gel appear to be an effective and safe alternative to repair facial lipoatrophy, at least up to 48 weeks, significantly improving patient quality of life. Similar results were observed for all degrees of severity and between genders. Polyacrylamide gel provided the longest lasting benefits.

Background Switching from PIs to dolutegravir in virologically suppressed HIV-infected individuals has not been assessed. Objectives The principal aim was to assess the evolution of bone mineral density (BMD) when switching from a ritonavir-boosted PI to dolutegravir in HIV-infected patients with osteopenia or osteoporosis. The secondary objective was to assess the antiviral efficacy and safety of the switch therapy. Methods This randomized, multicentre study assessed changes in BMD, bone turnover markers, and antiviral efficacy and safety in 73 virologically suppressed patients with osteopenia/osteoporosis taking a ritonavir-boosted PI plus abacavir/lamivudine who were randomized to switch from PI to dolutegravir (DOLU group, n = 37) or continue with a PI (PI group, n = 36). Clinical Trials: NCT02577042. Results One and three patients from the DOLU and PI groups, respectively, withdrew prematurely (unrelated to treatment). At 48 weeks, 97.3% versus 91.7%, respectively, maintained viral suppression (snapshot analysis, ITT, M = F). No significant differences were seen between the groups in percentage change from baseline to week 48 in femoral ( P = 0.56) and lumbar spine ( P = 0.29) BMD, although lumbar spine BMD improved by 1.43% (-1.36; 2.92) in the DOLU group [0.12% (-2.83; 2.89) in the PI group]. Bone marker values did not vary significantly. At week 48, triglycerides were lower ( P < 0.001) and HDL cholesterol higher ( P = 0.027) in the DOLU group. Conclusions Dolutegravir + Kivexa ® was safe and well-tolerated in virologically suppressed patients receiving a PI-based regimen. The lipid profile was better, albeit without significant changes in BMD, probably because of the short follow-up.

Low bone mineral density (BMD) is an emerging metabolic condition in HIV-infected patients; however, data on progression of this disease are scarce.We studied 671 patients with at least one dual-energy X-ray absorptiometry scan (391 of them ≥2 scans) to determine the prevalence and progression of BMD and establish related factors. Linear regression and logistic polytomic regression were used for the cross-sectional study and mixed effects and generalized estimating equations were used for the longitudinal study.Osteopenia and osteoporosis were diagnosed in 47.5 and 23%, respectively. Progression to bone demineralization was observed in 28% of the patients over a median of 2.5 years (12.5% progressed to osteopenia and 15.6% to osteoporosis). In the 105 patients with at least 5 years of follow-up, progression was 47% (18% to osteopenia; 29% to osteoporosis). Factors associated with bone loss and progression were age [odds ratio (OR) 1.07; 95% confidence interval (CI) 1.05-1.08; P0.0001], male sex (OR 2.23; 95% CI 1.77-2.8; P0.0001), low body mass index (OR 1.14; 95% CI 1.11-1.17; P0.0001), time on protease inhibitor (OR 1.18; 95% CI 1.12-1.24; P0.0001), time on tenofovir (OR 1.08; 95% CI 1.03-1.14; P0.0019), and current use of protease inhibitors (OR 1.64; 95% CI 1.35-2.04; P0.0001).Our results show a high prevalence of and considerable progression to osteopenia/osteoporosis in our cohort. Our findings support the importance of applying adequate strategies to prevent bone demineralization and of close monitoring of BMD in HIV-infected patients, specifically in at-risk patients who are taking antiretrovirals that affect bone mineralization.

Infiltrations with synthetic substances are effective strategies for repairing facial lipoatrophy. However, few data are available on long-term safety. We describe the safety of polyacrylamide hydrogel in 145 patients who received facial infiltrations with Aquamid from September 2002 to April 2004. Epidemiological, clinical (mainly complications), and psychological data (patient satisfaction) were collected. We also recorded all patients who presented with a local infection at any time after receiving an infiltration. Sixty-two percent of patients presented with severe facial lipoatrophy before infiltration. The cumulative volume of Aquamid injected was 5.5 ml (4-18) per patient. During a mean (SD) of 50.2 (4.3) months after infiltration, only one patient presented with a local infection. Small palpable, nonvisible nodules or indurations were the most frequent complications (19.3% and 6.2%, respectively). If we include the remaining patients from our center (n = 294) who also received Aquamid (although less than 4 years ago), a further three patients presented with a local infection (incidence of 0.9%). Most patients (88.9%) were "satisfied" or "very satisfied" with the results; patients with mild to moderate baseline facial lipoatrophy were more satisfied than those with severe lipoatrophy ("very satisfied": 92.7% versus 86.5%, respectively). Only 17.4% reported mild impairment of lipoatrophy and only 9.2% required new infiltrations; however, 76% would have preferred more infiltrations. The high patient satisfaction and the low number of severe complications after at least 4 years of facial infiltrations with Aquamid reflect the long-term safety of this product for the repair of facial lipoatrophy. However, prolonged follow-up of these patients is recommended to detect unexpected long-term adverse reactions.
