Long-term retention on antiretroviral therapy among infants, children, adolescents and adults in Malawi: A cohort study.

ABSTRACT: OBJECTIVES:We examine long-term retention of adults, adolescents and children on antiretroviral therapy under different HIV treatment guidelines in Malawi. DESIGN:Prospective cohort study. SETTING AND PARTICIPANTS:Adults and children starting ART between 2005 and 2015 in 21 health facilities in southern Malawi. METHODS:We used survival analysis to assess retention at clinic level, Cox regression to examine risk factors for loss to follow up, and competing risk analysis to assess long-term outcomes of people on antiretroviral therapy (ART). RESULTS:We included 132,274 individuals in our analysis, totalling 270,256 person years of follow up (PYFU; median per patient 1.3, interquartile range (IQR) 0.26-3.1), 62% were female and the median age was 32 years. Retention on ART was lower in the first year on ART compared to subsequent years for all guideline periods and age groups. Infants (0-3 years), adolescents and young adults (15-24 years) were at highest risk of LTFU. Comparing the different calendar periods of ART initiation we found that retention improved initially, but remained stable thereafter. CONCLUSION:Even though the number of patients and the burden on health care system increased substantially during the study period of rapid ART expansion, retention on ART improved in the early years of ART provision, but gains in retention were not maintained over 5 years on ART. Reducing high attrition in the first year of ART should remain a priority for ART programs, and so should addressing poor retention among adolescents, young adults and men.

Project description:UnlabelledVery little is known about the psychological consequences of a cardiac arrest (CA) during childhood. Our aim was to assess long-term emotional and behavioral functioning, and its predictors, in survivors of CA in childhood. This long-term follow-up study involved all consecutive infants, children, and adolescents surviving CA in a tertiary-care university children's hospital between January 2002 and December 2011. Emotional and behavioral functioning was assessed with the Child Behavior Checklist (CBCL), Teacher's Report Form (TRF), and Youth Self-Report (YSR). Of the eligible 107 CA survivors, 52 patients, parents, and/or teachers filled out online questionnaires. Compared with normative data, parents and teachers reported significantly more attention and somatic problems (age range 6-18 years). Parents also reported more attention problems for age range 1.5-5 years. Twenty-eight percent of the children (n?=?14) scored in the psychopathological range (i.e., for age range 1.5-18 years; p?<?0.001) according to parent reports. Male gender, older age, and basic life support were significantly related to worse scores on the scales internalizing problems, externalizing problems, and total problems and subscale attention problems.ConclusionLong-term deficits in attention and somatic complaints were reported. Attention problems after childhood CA can interfere with school performance. Long-term follow-up with neuropsychological assessment should be organized.What is known• Critical illness has a significant influence on the presence of long-term emotional and behavioral problems. • Long-term emotional and behavioral problems have been described for various groups of critically ill children such as congenital heart disease, meningococcal septic shock, and neonatal asphyxia. What is new: • This is the first study that addresses long-term emotional and behavioral problems in a relatively large consecutive series of children and adolescents surviving cardiac arrest. • Long-term deficits in attention and somatic complaints were reported.

Project description:A long-term follow-up was made of 12 elbows operated upon between 1971 and 1986, with more than 20 years' follow-up, in nine males and three females, age at the time of surgery between 10 and 19 years . Eight right and four left elbows were involved, and there were three aetiological causes. Seven cases were sequelae of elbow fractures, of which five were supracondylar and two were of the olecranon. There were four cases of juvenile rheumatoid arthritis and one was post-osteomyelitis. The surgical technique involved a modification made by Vainio of MacAusland's technique (wider resection of the osseous ends and total covering of the bloody surfaces) [5, 9]. After extirpating the tissue blocking the joint, we proceeded to remodel the distal humerus in a wide V shape, the proximal end of the ulnar and, if necessary, the radial head. The proximal end of the ulna was sectioned transversely. All surgery was carried out sub-periosteally. Then, an interposition material was placed in one piece and sutured over the distal humerus and cut ends of the ulna and radius. The articular ends were brought together, and the capsule was closed using equidistant stitching, as is the skin. A small compression bandage was applied, and the arm was immobilised with a collar and cuff sling, with the forearm flexed to slightly less than a right angle. In ten cases, the interposition material was fascia lata grafts; in one case, skin graft and in one case, Gelfoam graft. Early rehabilitation began when post-operative pain allowed. Follow-up ranged from 25 to 32 years. Pre-surgical movement ranged between 90 degrees and 120 degrees of flexion and 30 degrees and 90 degrees of extension. Post-operative range varied between 90 degrees and 150 degrees of flexion. The five cases of full pre-operative ankylosis achieved between 90 degrees and 150 degrees of flexion and between 0 degrees and 70 degrees of extension. The total range of motion at the latest follow-up varied from 35 degrees to 150 degrees . Patients who were able to perform flexion of 120 degrees or more were considered to be excellent, those between 90 degrees and 119 degrees were graded good, from 60 degrees to 89 degrees fair and those 59 degrees or less poor. The ability to attain a hand to mouth position requires a mobility of 120 degrees . We obtained excellent results in two patients, good results in three, fair results in four and poor results in three. The fascia lata was used in 83% of cases, obtaining excellent to good results in five patients (41%). Elbow interposition arthroplasty has its indications in children and adolescents where arthrodesis or total joint replacement cannot be performed.

Project description:BackgroundKey populations (KP) are disproportionately infected with HIV and experience barriers to HIV care. KP include men who have sex with men (MSM), female sex workers (FSW), persons who inject drugs (PWID) and transgender people (TG). We implemented three different approaches to the delivery of community-based antiretroviral therapy for KP (KP-CBART) in Benue State Nigeria, including One Stop Shop clinics (OSS), community drop-in-centres (DIC), and outreach venues. OSS are community-based health facilities serving KP only. DIC are small facilities led by lay healthcare providers and supported by an outreach team. Outreach venues are places in the community served by the outreach team. We studied long-term attrition of KP and virological non-suppression.MethodThis is a retrospective cohort study of KP living with HIV (KPLHIV) starting ART between 2016 and 2019 in 3 0SS, 2 DIC and 8 outreach venues. Attrition included lost to follow-up (LTFU) and death. A viral load >1000 copies/mL showed viral non-suppression. Survival analysis was used to assess retention on ART. Cox regression and Firth logistic regression were used to assess risk factors for attrition and virological non-suppression respectively.ResultOf 3495 KPLHIV initiated on ART in KP-CBART, 51.8% (n = 1812) were enrolled in OSS, 28.1% (n = 982) in DIC, and 20.1% (n = 701) through outreach venues. The majority of participants were FSW-54.2% (n = 1896), while 29.8% (n = 1040), 15.8% (n = 551) and 0.2% (n = 8) were MSM, PWID, and TG respectively. The overall retention in the programme was 63.5%, 55.4%, 51.2%, and 46.7% at 1 year, 2 years, 3 years, and 4 years on ART. Of 1650 with attrition, 2.5% (n = 41) died and others were LTFU. Once adjusted for other factors (age, sex, place of residence, year of ART enrollment, WHO clinical stage, type of KP group, and KP-CBART approach), KP-CBART approach did not predict attrition. MSM were at a higher risk of attrition (vs FSW; adjusted hazard ratio (aHR) 1.27; 95%CI: 1.14-1.42). Of 3495 patients, 48.4% (n = 1691) had a viral load test. Of those, 97.8% (n = 1654) were virally suppressed.ConclusionAlthough long-term retention in care is low, the virological suppression was optimal for KP on ART and retained in community-based ART care. However, viral load testing coverage was sub-optimal. Future research should explore the perspectives of clients on reasons for LTFU and how to adapt approach to CBART to meet individual client needs.

Project description:BACKGROUND:The International Maternal Pediatric Adolescent AIDS Clinical Trials Network (IMPAACT) P1060 study demonstrated short-term superiority of lopinavir/ritonavir (LPV/r) over nevirapine (NVP) in antiretroviral therapy (ART), regardless of prior NVP exposure. However, NVP-based ART had a marginal benefit in CD4 percentage (CD4%) and growth. We compared 5-year outcomes from this clinical trial. METHODS:Human immunodeficiency virus (HIV)-infected, ART-eligible children were enrolled into 2 cohorts based on prior NVP exposure and randomized to NVP- or LPV/r-based ART. The data safety monitoring board recommended unblinding results in both cohorts due to superiority of LPV/r for the primary endpoint: stopping randomized treatment, virologic failure (VF), or death by 6 months. Participants were offered a switch in regimens (if on NVP) and continued observational follow-up. We compared time to VF or death, death, and CD4% and growth changes using intention-to-treat analyses. Additionally, inverse probability weights were used to account for treatment switching and censoring. RESULTS:As of September 2014, 329 of the 451 (73%) enrolled participants were still in follow-up (median, 5.3 years; interquartile range [IQR], 4.3-6.4), with 52% on NVP and 88% on LPV/r as originally randomized. NVP arm participants had significantly higher risk of VF or death (adjusted hazard ratio [aHR], 1.90; 95% confidence interval [CI], 1.37-2.65) but not death alone (aHR, 1.65; 95% CI, .72-3.76) compared with participants randomized to LPV/r. Mean CD4% was significantly higher in the NVP arm up to 1 year after ART initiation, but not beyond. Mean weight-for-age z scores were marginally higher in the NVP arm, but height-for-age z scores did not differ. Similar trends were observed in sensitivity analyses. CONCLUSIONS:These findings support the current World Health Organization recommendation of LPV/r in first-line ART regimens for HIV-infected children. CLINICAL TRIALS REGISTRATION:NCT00307151.

Project description:BACKGROUND:The long-term benefits of antiretroviral treatment (ART) are associated with metabolic complications, especially lipodystrophy, which has been well described among HIV-infected adults and children on ART in developed settings. Specifically, stavudine, and to a lesser extent zidovudine and protease inhibitors (PI), have been consistently implicated in the development of lipodystrophy. In 2006, following advice from the WHO, Senegal began phasing out stavudine from first-line ART. The objectives of this cross-sectional analysis are to assess and identify risk factors affecting the prevalence of lipodystrophy in Senegalese children and adolescents on long-term ART participating in a cohort study. METHODS:Lipodystrophy was clinically assessed in two- to 18-year-old children on ART for at least six months and with no concurrent severe acute malnutrition. Risk factors for lipodystrophy were identified using stepwise multivariable logistic regression. Explanatory variables included clinical and personal data, immunovirologic status, and therapeutic history. RESULTS:Overall, 254 children were assessed for lipodystrophy. The median age was 10.9 years (IQR: 8.1-14.2) and the median duration on ART was 54 months (32-84). Only 18% had been previously treated with stavudine, with a median treatment duration of 8 months (5-25). Ongoing treatment included 76% of children receiving zidovudine (median duration of 48 months (26-74)) and 27% receiving PI (lopinavir/ritonavir; median duration of 49 months (23-59)). Mild signs of lipodystrophy were observed in 33 children (13%): 28 with lipoatrophy, 4 with lipohypertrophy and one with combined type. Boys were more likely to present with lipoatrophy than girls (aOR: 4.3, 95% CI: 1.6-11.7). Children previously treated with stavudine for ?1 year had a greater risk for lipoatrophy than those never exposed (3.8, 1.0-14.0), although the association was weak. There was no association between lipodystrophy and age or current or cumulative treatment with lopinavir/ritonavir or zidovudine. CONCLUSIONS:We report low prevalence of mild lipodystrophy in children and adolescents on long-term ART receiving a stavudine-sparing regimen. These findings are reassuring for clinicians in low-income settings where zidovudine is massively prescribed and lopinavir/ritonavir is the only widely available PI.
