Unlocking the potential: exploring the impact of dolutegravir treatment on body mass index improvement in underweight adults with HIV in Malawi. BMC Public Health 2024; 24:1321. [PMID: 38755632 PMCID: PMC11097535 DOI: 10.1186/s12889-024-18818-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 05/09/2024] [Indexed: 05/18/2024] Open
Abstract
BACKGROUND The introduction of dolutegravir (DTG) in treating HIV has shown enhanced efficacy and tolerability. This study examined changes in weight gain and body mass index (BMI) at 6- and 12-months after post-initiating antiretroviral therapy (ART), comparing people living with HIV (PLHIV) on DTG-based regimens with those on non-DTG-based regimens in Malawi. METHODS Retrospective cohort data from 40 public health facilities in Malawi were used, including adult ART patients (aged ≥ 15 years) from January 2017 to March 2020. The primary outcomes were BMI changes/transitions, with secondary outcomes focused on estimating the proportion of mean weight gain > 10% post-ART initiation and BMI category transitions. Descriptive statistics and binomial regression were used to estimate the unadjusted and adjusted relative risks (RR) of weight gain of more than ( >) 10%. RESULTS The study included 3,520 adult ART patients with baseline weight after ART initiation, predominantly female (62.7%) and aged 25-49 (61.1%), with a median age of 33 years (interquartile range (IQR), 23-42 years). These findings highlight the influence of age, ART history, and current regimen on weight gain. After 12months follow up, compared to those aged 15-24 years, individuals aged 25-49 had an Adjusted RR (ARR) of 0.5 (95% Confidence Interval (CI): 0.35-0.70), suggesting a 50% reduced likelihood of > 10% weight gain after post-ART initiation. Similarly, those aged 50 + had an ARR of 0.33 (95% CI: 0.20-0.58), indicating a 67% decreased likelihood compared to the youngest age group 15-24 years. This study highlights the positive impact of DTG-based regimens, revealing significant transitions from underweight to normal BMI categories at 6- and 12-months post-initiation. CONCLUSION This study provides insights into weight gain patterns in patients on DTG-based regimens compared with those on non-DTG regimens. Younger individuals (15-24 years) exhibited higher odds of weight gain, suggesting a need for increased surveillance in this age group. These findings contribute to the understanding DTG's potential effects on weight gain, aiding clinical decision making. Further research is required to comprehensively understand the underlying mechanisms and long-term implications of weight gain in patients receiving DTG-based regimens.

Abstract
OBJECTIVE To measure the incidence of neuropsychiatric adverse drug reactions (ADRs) in individuals living with HIV who initiated antiretroviral therapy (ART) with first-line regimens containing dolutegravir (DTG) or efavirenz (EFV) and associated factors. METHODS Prospective cohort study with individuals living with HIV who started ART with DTG or EFV associated with tenofovir disoproxil and lamivudine in Belo Horizonte, Brazil. Sociodemographic, clinical, and laboratory data were collected from September 2015 to October 2018 in three specialized HIV care services through interviews, clinical records, and computerized systems. We analysed the frequency of neuropsychiatric ADRs recorded in clinical records 12 months after starting antiretroviral use, and the associated factors were investigated using binary logistic regression. RESULTS A total of 152 (35.1%) of the 433 individuals included had neuropsychiatric ADRs. The incidence density was 35.3/100 person-years. The subjects mainly had sleep disorders and disturbances (21.3%), neurological disorders (13.9%), headaches (8.1%), and anxiety disorders and symptoms (3.0%), more frequently in individuals using EFV. A lower likelihood of neuropsychiatric ADRs was associated with using a DTG-based antiretroviral regimen (OR = 0.24; 95% CI = 0.14-0.40) and anxiety or depression signs and symptoms at the onset of treatment (OR = 0.57; 95% CI = 0.37-0.89). CONCLUSION The incidence of neuropsychiatric ADRs was high in individuals starting ART with a lower likelihood of using a DTG-based regimen. The DTG-based regimen had a better safety profile for neuropsychiatric ADRs than the EFV-based regimen.

Dolutegravir Discontinuation for Neuropsychiatric Symptoms in People Living with HIV and Their Outcomes after Treatment Change: A Pharmacogenetic Study. Metabolites 2022; 12:metabo12121202. [PMID: 36557240 PMCID: PMC9781993 DOI: 10.3390/metabo12121202] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 11/24/2022] [Accepted: 11/27/2022] [Indexed: 12/04/2022] Open
Abstract
Neuropsychiatric symptoms have been reported in patients receiving dolutegravir, a known inhibitor of the renal and neuronal-expressed organic anion transporter 2 (encoded by SLC22A2 gene). The effect of the genetic variant SLC22A2 808C>A on dolutegravir discontinuation was assessed and analyzed by real-time PCR. We enrolled 627 participants: CA/AA carriers showed a higher prevalence of pre-existing psychiatric comorbidities and use of antidepressants. After 27.9 months, 108 participants discontinued dolutegravir, 64 for neuropsychiatric symptoms. Patients with pre-existing psychiatric comorbidities were at higher risk of dolutegravir discontinuation, while patients carrying the SLC22A2 CA/AA genotype were not. Combining the two variables, an opposite effect of SLC22A2 variants according to pre-existing psychiatric disorders was observed. Using multivariate Cox models, the combined variable pre-existing psychiatric comorbidities/SLC22A2 variants and the use of non-tenofovir alafenamide containing antiretroviral regimens were predictors of dolutegravir discontinuation for neuropsychiatric symptoms. Within 30 days, the majority of participants had a complete resolution of symptoms (61.8%), while 32.7% and 5.5% had partial or no change after dolutegravir discontinuation, respectively. Discontinuation of dolutegravir for neuropsychiatric symptoms was not uncommon and more frequent in participants with pre-existing psychiatric disorders. We described an interaction between SLC22A2 genetic variant and psychiatric comorbidities. In 38.2% of patients, a complete neuropsychiatric symptoms resolution was not observed after dolutegravir discontinuation suggesting the involvement of additional factors.

Efficacy and Safety of a Simplified Lamivudine Plus Dolutegravir Dual Therapy in HIV-1-Infected Patients: A Multicenter Cohort Study in China. J Acquir Immune Defic Syndr 2022; 91:S42-S50. [PMID: 36094514 DOI: 10.1097/qai.0000000000003047] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Accepted: 02/11/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND Results from both clinical trials and real-world observational studies suggest that lamivudine plus dolutegravir (3TC + DTG) dual therapy has excellent virological efficacy and safety in HIV-1-infected patients. However, there is still no relevant study related to this dual therapy reported in China. METHODS In this multicenter, retrospective, observational study that included HIV-1-infected patients in China, baseline and follow-up data were collected to analyze the virological suppression rate, immune restoration, and adverse events during follow-up in HIV-1-infected patients who switched to the 3TC + DTG dual therapy. RESULTS This study recruited 112 HIV-1-infected patients, including 101 men (90.2%), with a median age of 44.0 years (IQR: 33.00-57.75) and median CD4+ T-cell count of 432.13 cells/μL (IQR: 237.75-578.50). The overall virological suppression rate was 94.5% at the 24-week follow-up. However, the virological suppression rates of men who have sex with men patients and patients with CD4+ T-cell count of <350 cells/μL were higher than the baseline value (P < 0.05) at week 24. The results of Cox regression analysis showed that the baseline CD4+ T-cell count was an independent determinant of immune restoration in patients, and patients with baseline CD4+ T-cell count of 350-500 cells/μL outperformed patients with baseline CD4+ T-cell count of <350 cells/μL in immune restoration (hazard ratio: 4.469, 95% confidence interval: 1.801 to 11.091, P = 0.001). Adverse events were reported in 5 patients (incidence rate of 4.5%); among them, 3 patients developed neuropsychiatric symptoms. Results from the laboratory data analysis showed that patients with grade 1 and 2 adverse events had elevated levels of low-density lipoprotein cholesterol and total bilirubin. Furthermore, grade 3 and 4 adverse events were associated with the elevation of blood glucose level in 4 patients. CONCLUSIONS Thus, the 3TC + DTG dual therapy displayed an excellent virological efficacy against HIV-1 infections and had an acceptable safety profile, with predominantly mild adverse events in HIV-1-infected patients in China.

Abstract
The purpose of this study is to evaluate the frequency of central nervous system adverse events (CNS-AE) on dolutegravir (DTG) and non-DTG containing ART, and their reversibility, in the observational prospective SCOLTA cohort. Factors associated with CNS-AE were estimated using a Cox proportional-hazards model. 4939 people living with HIV (PLWH) were enrolled in DTG (n = 1179) and non-DTG (n = 3760) cohorts. Sixty-six SNC-AE leading to ART discontinuation were reported, 39/1179 (3.3%) in DTG and 27/3760 (0.7%) in non-DTG cohort. PLWH naïve to ART, with higher CD4 + T count and with psychiatric disorders were more likely to develop a CNS-AE. The risk was lower in non-DTG than DTG-cohort (aHR 0.33, 95% CI 0.19−0.55, p < 0.0001). One-year follow-up was available for 63/66 PLWH with CNS-AE. AE resolution was reported in 35/39 and 23/24 cases in DTG and non-DTG cohorts, respectively. The probability of AE reversibility was not different based on ART class, sex, ethnicity, CDC stage, or baseline psychiatric disorder. At the same time, a lower rate of event resolution was found in PLWH older than 50 years (p = 0.017). In conclusion, CNS-AE leading to ART discontinuation was more frequent in DTG than non-DTG treated PLWH. Most CNS-AE resolved after ART switch, similarly in both DTG and non-DTG cohorts.

Abstract
INTRODUCTION There are more than 30 agents available for the treatment of HIV with guidelines shifting toward integrase strand transfer inhibitors (INSTIs) as part of first line therapy. The fixed dose combination of dolutegravir (DTG), abacavir (ABC), and lamivudine (3TC) is a convenient, well tolerated, and highly effective option for treating HIV infection and remains a first line therapy across several prominent guidelines. AREAS COVERED In this drug evaluation, the authors provide a comprehensive overview of DTG/ABC/3TC for the treatment of HIV including the pharmacokinetics, pharmacodynamics, efficacy, safety, and tolerability. The authors also provide the reader with their expert perspectives on this particular treatment strategy. EXPERT OPINION While DTG/ABC/3TC remains a valuable HIV treatment option, newer combination regimens have entered the market. Bictegravir with tenofovir alafenamide and emtricitabine offers the benefit of same day initiation and efficacy in hepatitis B co-infection, while new two-drug regimens enhance the simplicity of HIV treatment. Continued study is required into the mechanisms and optimal management strategies for weight gain for many regimens, including DTG/ABC/3TC.

Abstract
OBJECTIVES Dolutegravir is a second-generation integrase strand transfer inhibitor of particular interest as a rescue treatment for people living with HIV (PLWHIV) who develop resistance to multiple antiretrovirals (ART). We assessed the virological treatment response in patients switched to a dolutegravir-based regimen following failure of previous ART treatment in a real-world treatment setting. PATIENTS AND METHODS This was a multicenter, longitudinal, observational study with retrospective patient enrolment. Patients were enrolled between February 2017 and January 2018. Patients starting dolutegravir treatment between February 2014 and September 2016 were retrospectively included. Patients were followed up for 24 months after dolutegravir initiation. During this period, treatment with dolutegravir could be discontinued at any time at the physician's discretion. Treatment failure was either defined as a viral load ≥50 copies/mL at two consecutive blood samples or as clinical or biological safety issues. Overall, 459 patients were enrolled and 329 completed 24 months of treatment. The primary study outcome measures were treatment response and time to treatment response. RESULTS 346/440 patients (78.6%) achieved a treatment response; 86 patients discontinued dolutegravir treatment (of whom 17 for failure to achieve or maintain viral suppression and 38 for tolerability issues). Acquired dolutegravir-resistance mutations were identified in five patients. CONCLUSIONS A sustained treatment response can be obtained with a dolutegravir-based treatment regimen in PLWHIV experiencing treatment failure, even in vulnerable patients with a long history of previous ART failure, infected with multidrug-resistant HIV strains, and with multiple comorbidities.

Abstract
PURPOSE OF REVIEW Neuropsychiatric adverse effects (NPAE) associated with integrase strand transfer inhibitors (INSTIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs) are a growing concern, with higher rates in the real-world compared to phase III trials. This paper reviews the incidence, risk factors, and management of NPAE with second-generation INSTIs, INSTI/rilpivirine dual therapy, and doravirine. RECENT FINDINGS Recent cohort data confirm up to 8% NPAE-associated discontinuations for dolutegravir; NPAE with dolutegravir/rilpivirine therapy are higher than with dolutegravir alone, whereas bictegravir appears similar to dolutegravir. In contrast, NPAE with cabotegravir alone or with rilpivirine appears to be low. Doravirine has NPAE rates similar to rilpivirine and lower than efavirenz. Risk factors for NPAE include female gender, concurrent abacavir use, Sub-Saharan African descent, and age, whereas underlying psychiatric conditions do not appear to increase risk. Strategies to manage NPAE include changing administration time, therapeutic drug monitoring, or regimen modification including within-class INSTI changes. People experiencing NPAE with dolutegravir may tolerate bictegravir. SUMMARY Overall, mild to moderate NPAE are associated with INSTIs and newer NNRTIs. Rarely, more severe symptoms may occur and lead to treatment discontinuation. Clinicians should be aware of NPAE to identify and manage drug-related adverse effects.

Abstract
This study evaluates the frequency and causes of dolutegravir (DTG) discontinuation along 5 years of follow-up, in both antiretroviral treatment (ART)-naive and experienced people living with HIV (PLWH). This is a prospective multi-center cohort study enrolling PLWH on DTG from July 2014 until November 2020. DTG-durability was investigated using the Kaplan-Meier survival curve. The Cox proportional-hazards model was used for estimating the hazard ratio (HR) of DTG discontinuation for any cause, and for adverse events (AEs). Nine hundred sixty-three PLWH were included, 25.3% were women and 28.0% were ART-naive. Discontinuations for any causes were 10.1 [95% confidence interval (95% CI) 8.9-11.5] per 100 person-years, similar in most regimens, with the apparent exception of tenofovir alafenamide/emtricitabine+DTG (p < 0.0001). In the multivariable Cox regression model, non-Caucasian ethnicity, age ≥50 years, and lower estimated glomerular filtration rate (eGFR) were associated with a higher probability of DTG interruption. The incidence rate of virological failure was 0.4 (95% CI 0.2-0.7) per 100 person-years, while the estimated discontinuation rate for AEs was 4.0 (3.2-4.9) per 100 person-years. Thirty-four DTG interruptions were due to grade ≥3 events (10 central nervous system, 6 hypersensitivity, 3 renal, 3 myalgia/asthenia, 3 abdominal pain, 2 gastrointestinal, and 7 other events). People with lower body mass index, age ≥50 years, and lower eGFR were at higher risk of AEs, while dual combinations were protective (HR 0.41 compared with abacavir/lamivudine/DTG, 95% CI 0.22-0.77). In this prospective observational study, we found high DTG durability and a low rate of virological failures. Dual therapies seemed protective toward AEs and might be considered, when feasible, a suitable option to minimize drug interactions and improve tolerability.
