RESUMO

Despite cancer being a leading comorbidity amongst individuals with HIV, there are limited data assessing cancer trends across different antiretroviral therapy (ART)-eras. We calculated age-standardised cancer incidence rates (IRs) from 2006-2021 in two international cohort collaborations (D:A:D and RESPOND). Poisson regression was used to assess temporal trends, adjusted for potential confounders. Amongst 64,937 individuals (31% ART-naïve at baseline) and 490,376 total person-years of follow-up (PYFU), there were 3763 incident cancers (IR 7.7/1000 PYFU [95% CI 7.4, 7.9]): 950 AIDS-defining cancers (ADCs), 2813 non-ADCs, 1677 infection-related cancers, 1372 smoking-related cancers, and 719 BMI-related cancers (groups were not mutually exclusive). Age-standardised IRs for overall cancer remained fairly constant over time (8.22/1000 PYFU [7.52, 8.97] in 2006-2007, 7.54 [6.59, 8.59] in 2020-2021). The incidence of ADCs (3.23 [2.79, 3.72], 0.99 [0.67, 1.42]) and infection-related cancers (4.83 [4.2, 5.41], 2.43 [1.90, 3.05]) decreased over time, whilst the incidence of non-ADCs (4.99 [4.44, 5.58], 6.55 [5.67, 7.53]), smoking-related cancers (2.38 [2.01, 2.79], 3.25 [2.63-3.96]), and BMI-related cancers (1.07 [0.83, 1.37], 1.88 [1.42, 2.44]) increased. Trends were similar after adjusting for demographics, comorbidities, HIV-related factors, and ART use. These results highlight the need for better prevention strategies to reduce the incidence of NADCs, smoking-, and BMI-related cancers.

RESUMO

BACKGROUND: Weight gain effects of individual antiretroviral drugs are not fully understood. We investigated associations between a prespecified clinically significant increase (>7%) in body-mass index (BMI) and contemporary antiretroviral use. METHODS: The International Cohort Consortium of Infectious Diseases (RESPOND) is a prospective, multicohort collaboration, including data from 17 well established cohorts and over 29 000 people living with HIV. People with HIV under prospective follow-up from Jan 1, 2012, and older than 18 years were eligible for inclusion. Each cohort contributed a predefined minimum number of participants related to the size of the specific cohort (with a minimum of 1000 participants). Participants were required to have CD4 cell counts and HIV viral load measurement in the 12 months before or within 3 months after baseline. For all antiretroviral drugs received at or after RESPOND entry, changes from pre-antiretroviral BMI levels (baseline) were considered at each BMI measurement during antiretroviral treatment. We used logistic regression to identify individual antiretrovirals that were associated with first occurrence of a more than 7% increase in BMI from pre-antiretroviral BMI. We adjusted analyses for time on antiretrovirals, pre-antiretroviral BMI, demographics, geographical region, CD4 cell count, viral load, smoking status, and AIDS at baseline. RESULTS: 14 703 people were included in this study, of whom 7863 (53·5%) had a more than 7% increase in BMI. Compared with lamivudine, use of dolutegravir (odds ratio [OR] 1·27, 95% CI 1·17-1·38), raltegravir (1·37, 1·20-1·56), and tenofovir alafenamide (1·38, 1·22-1·35) was significantly associated with a more than 7% BMI increase, as was low pre-antiretroviral BMI (2·10, 1·91-2·31 for underweight vs healthy weight) and Black ethnicity (1·61, 1·47-1·76 vs White ethnicity). Higher CD4 count was associated with a reduced risk of BMI increase (0·97, 0·96-0·98 per 100 cells per µL increase). Relative to lamivudine, dolutegravir without tenofovir alafenamide (OR 1·21, 95% CI 1·19-1·32) and tenofovir alafenamide without dolutegravir (1·33, 1·15-1·53) remained independently associated with a more than 7% increase in BMI; the associations were higher when dolutegravir and tenofovir alafenamide were used concomitantly (1·79, 1·52-2·11, and 1·70, 1·44-2·01, respectively). INTERPRETATION: Clinicians and people with HIV should be aware of associations between weight gain and use of dolutegravir, tenofovir alafenamide, and raltegravir, particularly given the potential consequences of weight gain, such as insulin resistance, dyslipidaemia, and hypertension.

RESUMO

Among men who have sex with men (MSM) in low- or middle-income countries, smoking and related factors have been understudied. We examined correlates of smoking status, level, and importance and confidence regarding quitting among 608 MSM in the country of Georgia recruited in June-September, 2016 (493 without HIV via peer referral in 3 Georgian cities; 115 with HIV via the National AIDS Center). Median age was 26 years, 78.6% reported current (past 30-day) alcohol use, and 22.4% reported past-year illicit drug use. Overall, 73.8% reported current smoking; of these, 87.1% smoked daily, mean cigarettes per day (cpd) was 19.8, 64.6% smoked ≤30 min of waking, and mean quitting importance and confidence were 6.8 and 6.4 (0 = not at all to 10 = extremely), respectively. Multivariable analyses indicated that current smoking correlated with past-month alcohol and past-year illicit drug use (p's < .001). Among smokers, cpd correlated with being older and smoking within 30 min of waking; greater quitting importance (≥7) correlated with higher education and no illicit substance use; and greater quitting confidence (≥7) was associated with fewer cpd, smoking ≤30 min of waking, and regional versus capital city residence. Given these findings, addressing tobacco and other substance use among MSM in Georgia is critical.

RESUMO

BACKGROUND: Limited data exist that compare clinical outcomes of 2-drug regimens (2DRs) and 3-drug regimens (3DRs) in people living with human immunodeficiency virus. METHODS: Antiretroviral treatment-experienced individuals in the International Cohort Consortium of Infectious Diseases (RESPOND) who switched to a new 2DR or 3DR from 1 January 2012-1 October 2018 were included. The incidence of clinical events (AIDS, non-AIDS cancer, cardiovascular disease, end-stage liver and renal disease, death) was compared between regimens using Poisson regression. RESULTS: Of 9791 individuals included, 1088 (11.1%) started 2DRs and 8703 (88.9%) started 3DRs. The most common 2DRs were dolutegravir plus lamivudine (22.8%) and raltegravir plus boosted darunavir (19.8%); the most common 3DR was dolutegravir plus 2 nucleoside reverse transcriptase inhibitors (46.9%). Individuals on 2DRs were older (median, 52.6 years [interquartile range, 46.7-59.0] vs 47.7 [39.7-54.3]), and a higher proportion had ≥1 comorbidity (81.6% vs 73.9%). There were 619 events during 27 159 person-years of follow-up (PYFU): 540 (incidence rate [IR] 22.5/1000 PYFU; 95% confidence interval [CI]: 20.7-24.5) on 3DRs and 79 (30.9/1000 PYFU; 95% CI: 24.8-38.5) on 2DRs. The most common events were death (7.5/1000 PYFU; 95% CI: 6.5-8.6) and non-AIDS cancer (5.8/1000 PYFU; 95% CI: 4.9-6.8). After adjustment for baseline demographic and clinical characteristics, there was a similar incidence of events on both regimen types (2DRs vs 3DRs IR ratio, 0.92; 95% CI: .72-1.19; P = .53). CONCLUSIONS: This is the first large, international cohort to assess clinical outcomes on 2DRs. After accounting for baseline characteristics, there was a similar incidence of events on 2DRs and 3DRs. 2DRs appear to be a viable treatment option with regard to clinical outcomes. Further research on resistance barriers and long-term durability of 2DRs is needed.

RESUMO

BACKGROUND: Georgia has one of the highest HCV prevalence in the world and launched the world's first national HCV elimination programs in 2015. Georgia set the ambitious target of diagnosing 90% of people living with HCV, treating 95% of those diagnosed and curing 95% of treated patients by 2020. We report outcomes of Sofosbuvir (SOF) based treatment regimens in patients with chronic HCV infection in Georgia. METHODS: Patients with cirrhosis, advanced liver fibrosis and severe extrahepatic manifestations were enrolled in the treatment program. Initial treatment consisted of SOF plus ribavirin (RBV) with or without pegylated interferon (INF). Sustained virologic response (SVR) was defined as undetectable HCV RNA at least 12 weeks after the end of treatment. SVR were calculated using both per-protocol and modified intent-to-treat (mITT) analysis. Results for patients who completed treatment through 31 October 2018 were analyzed. RESULTS: Of the 7342 patients who initiated treatment with SOF-based regimens, 5079 patients were tested for SVR. Total SVR rate was 82.1% in per-protocol analysis and 74.5% in mITT analysis. The lowest response rate was observed among genotype 1 patients (69.5%), intermediate response rate was achieved in genotype 2 patients (81.4%), while the highest response rate was among genotype 3 patients (91.8%). Overall, SOF/RBV regimens achieved lower response rates than IFN/SOF/RBV regimen (72.1% vs 91.3%, P < 0.0001). In multivariate analysis being infected with HCV genotype 2 (RR =1.10, CI [1.05-1.15]) and genotype 3 (RR = 1.14, CI [1.11-1.18]) were associated with higher SVR. Patients with cirrhosis (RR = 0.95, CI [0.93-0.98]), receiving treatment regimens of SOF/RBV 12 weeks, SOF/RBV 20 weeks, SOF/RBV 24 weeks and SOF/RBV 48 weeks (RR = 0.85, CI [0.81-0.91]; RR = 0.86, CI [0.82-0.92]; RR = 0.88, CI [0.85-0.91] and RR = 0.92, CI [0.87-0.98], respectively) were less likely to achieve SVR. CONCLUSIONS: Georgia's real world experience resulted in high overall response rates given that most patients had severe liver damage. Our results provide clear evidence that SOF plus IFN and RBV for 12 weeks can be considered a treatment option for eligible patients with all three HCV genotypes. With introduction of next generation DAAs, significantly improved response rates are expected, paving the way for Georgia to achieve HCV elimination goals.

RESUMO

Human immunodeficiency virus (HIV) drug resistance is a major threat to the sustained impact of antiretroviral therapy (ART). We studied the epidemiology of drug resistance in the country of Georgia. The study included all adult patients who experienced virologic failure on first line ART and received HIV drug resistance testing between 2005 and 2016. The Stanford HIV Sequence Database was used for interpretation of the resistance data. Patient-level data were extracted from the national AIDS health information system. Of the 447 patients included, 85.5% harbored the subtype A6 virus, 8.0% - subtype B, 2.9% - subtype G, and other subtypes were <1%. The most frequent first-line regimens were Tenofovir/Emtricitabine/Efavirenz (28.4%), Zidovudine/Lamivudine/Efavirenz (28.4%), and Abacavir/Lamivudine/Efavirenz (15.9%). A total of 85.0% of the patients with treatment failure developed at least one drug resistance mutation affecting their susceptibility to ART. The most frequent nucleoside reverse transcriptase inhibitor mutations were M184V (65.3%), K65R (19.7%) and L74V (17.0%). At least three thymidine analogue mutations were detected in 6.3% of the patients. From non-nucleoside reverse transcriptase inhibitor mutations, G190S was shown to be the most prevalent (49.4%), followed by K101E (27.10%) and K103N (24.4%). G190S and K101E were more common in subtype A as compared with non-A viruses (G190S: 54.9% vs 11.3%, P < 0.0001; K101E: 29.8% vs 11.3%, P = 0.005). On the other hand, K103N was more frequent in non-A subtypes (43.4%) compared with subtype A (22.2%), P = 0.0008. A majority of persons failing on ART had HIV drug resistance. Drug resistance patterns may vary by subtype. K65R mutation remains below 20%, but given the high use of Tenofovir in the country, continuing surveillance of drug resistance is needed.

RESUMO

INTRODUCTION: In developing a model of palliative care, the attitudes, needs, and requirements of its beneficiaries recognizing the limited remaining life expectancy need to be met. We aimed to map and compare these issues at the end of life in the groups of patients with advanced cancer and elderly individuals. MATERIALS AND METHODS: The prospective study based on the analysis of semistructured interviews was conducted. Fifty individuals aged older than 85 and 50 incurable patients with advanced cancer were studied. Transcripts of interviews were analyzed qualitatively (the interviews were divided into logically completed themes, and the compliance of each with one of the levels of Abraham Maslow pyramid was determined) and quantitatively (data comparisons of 2 groups were tested in bivariate analysis using Pearson χ2 or Fisher exact test. Two-sided significance tests were used; P value of <.05 was deemed significant). RESULTS: It was assumed that 120 themes were relevant to a certain level of Maslow pyramid. Their comparison showed small differences in the narratives of the patients with advanced cancer and elderly individuals aged 85 and older-concerning the past, present, and future terms of lives. In studied themes explicitly prevail the stories that are consistent with satisfaction of the upper levels of the hierarchy of needs and demands of Maslow: social relation (belonging), love, esteem, and transcendence. CONCLUSION: The attitudes, needs, and requirements at the end of life of the people are basically similar, regardless of what determined the sense of limitation of the remaining life-incurable disease or advanced age.

RESUMO

OBJECTIVE: We assessed the impact of direct-acting antiviral (DAA) therapy on liver fibrosis regression measured by transient elastography (TE) in patients with chronic hepatitis C virus (HCV) infection. PATIENTS AND METHODS: A prospective cohort study was carried out in HCV monoinfected patients with advanced liver fibrosis or cirrhosis receiving interferon (IFN)-containing or IFN-free DAA therapy. Liver stiffness (LS) score more than 14.5 kPa indicated LS-defined cirrhosis. The primary outcome was improvement in liver stiffness measurement (LSM) at week 24 after treatment measured as (a) decrease in the median LS compared with baseline and (b) at least a 20% decrease in LSM compared with baseline. A multivariate logistic regression model was utilized to identify the factors associated with at least a 20% improvement in LSM. RESULTS: Of a total of 304 patients, 172 (56.6%) had LS-defined cirrhosis before treatment. LSM decreased from the baseline median value of 16.9 (interquartile range: 11.8-27.7) kPa to a post-treatment week 24 score of 11.9 (interquartile range: 8.2-20.9) kPa (P<0.0001). Of a total of 304 patients, 198 (65.1%) achieved at least a 20% reduction in LS. In multivariate logistic regression analysis, sustained virological response (SVR) was associated significantly with this reduction (P<0.0001). The addition of IFN to the treatment regimen had no impact on the decrease in LSM. Despite decreasing baseline LSM, more than half of the LS-defined cirrhotic patients remained cirrhotic at week 24 after treatment. CONCLUSION: In patients with advanced fibrosis, pretreatment LS significantly reduced during DAA therapy. SVR was the only independent factor associated with the regression in LSM. However, irrespective of achieving SVR, liver damage still persisted in a substantial proportion of patients. Thus, early treatment of HCV-infected patients can significantly prevent residual liver damage.

RESUMO

BACKGROUND: Physicians working in critical and intensive care settings encounter death of chronic incurable patients on a daily basis; however they have scant skills on how to communicate with the patients and their family members. The aim of the present survey is to examine communication of critical and intensive care physicians with patients' family members receiving treatment due to chronic incurable diseases/conditions and to compare the views of families with physicians working in critical and intensive care settings. METHODS: The survey was conducted in four cities of Georgia (Tbilisi, Kutaisi, Batumi and Telavi) in 2014. Physicians working in critical and intensive care settings and family members were asked to fill in separate questionnaires, covering various aspects of communication including patients' prognosis, ways of death occurrence, treatment plans and religion. Participants ranked their responses on a scale ranging from "0" to "10", where "0" represented "never" and "10"-"always". After data collection, responses were recoded into three categories: 0-3 = never/rarely, 4-7 = somewhat and 8-10 = often/always. Differences were tested using Pearson's chi-square or Fisher's exact test as appropriate. P value of < 0.05 was considered as significant. RESULTS: Sixty-five physicians and 59 patients' family members participated in this cross-sectional study. Majority of their responses was statistically significantly different. Only one quarter (23.7 %) of family members of patients receiving medical aid in critical and intensive care settings were satisfied with the communication level. In contrast, 78.5 % of physicians considered their communication with families as positive (p < 0.0001). CONCLUSIONS: The survey revealed the mismatch between the views on communication of critical and intensive care settings physicians and family members of the patients with chronic incurable diseases receiving care in critical and intensive care settings. In order to provide the best care for chronic incurable patients and their family members, physicians working in critical and intensive care settings must have relevant clinical knowledge and ability to provide effective communication. Present results reflect important potential targets for educational interventions including critical and intensive care physicians training through online modules.
