Psychological Distress Increases 30-Fold Among People with HIV in the First Year on ART in Nigeria-a Call for Integrated Mental Health Services.

BACKGROUND: Few studies have longitudinally assessed psychological distress among people with HIV (PWH) initiating ART in resource-limited settings. METHOD: Baseline, 6-month, and 12-month psychological distress were measured in a Nigerian cohort newly initiating therapy; the relationship between baseline factors and psychological distress at 12 months was assessed; and the association between psychological distress at 12 months and care retention or immunologic failure was determined. RESULTS: Among 563 patients, median age was 38 years (IQR: 33-46 years), 62% were female, and 51% were married. Psychological distress increased from 3% at baseline to 34% at 12 months. Age (aOR 1.28, 95% CI 1.06-1.56), female sex (aOR 2.89, 95% CI 1.93-4.33), lack of disclosure (aOR 4.32, 95% CI 2.48-7.51), and time on ART (6 months [aOR 6.91, 95% CI 3.14-15.18] and 12 months [aOR 32.63, 95% CI 16.54-64.36]) were associated with psychological distress while being married (OR 0.42, 95% CI 0.30-0.61) was associated with reduced odds. Tweve-month psychological distress was associated with increased risk of immunologic failure (aOR 2.22, 95% CI 1.31-3.82). CONCLUSION: The risk of psychological distress increased 30-fold in the first year on therapy in PWH in Nigeria.

The patient-centered medical home: a reality for HIV care in Nigeria.

OBJECTIVE: HIV care delivery in resource-limited settings (RLS) may serve as a paradigm for chronic disease care, but comprehensive measurement frameworks are lacking. Our objective was to adapt the patient-centered medical home (PCMH) framework for use in RLS, and evaluate the performance of HIV treatment programs within this framework. DESIGN AND SETTING: Cross-sectional survey administered within the AIDS Prevention Initiative in Nigeria (APIN) network. PARTICIPANTS: Medical directors at APIN clinics. MAIN OUTCOME MEASURES: We adapted the 2011 US National Committee on Quality Assurance's PCMH standard to develop a survey measuring five domains of HIV care: (i) enhancing access and continuity, (ii) identifying and managing patient populations, (iii) planning and managing care, (iv) promoting self-care and support and (v) measuring and improving performance. RESULTS: Thirty-three of 36 clinics completed the survey. Most were public (73%) and urban/semi-urban (64%); 52% had >500 patients in care. On a 0-100 scale, clinics scored highest in self-care and support, 91% (63-100%); managing patient populations, 80% (72-81%) and improving performance, 72% (44-78%). Clinics scored lowest with the most variability in planning/managing care, 65% (22-89%), and access and continuity, 61% (33-80%). Average score across all domains was 72% (58-81%). CONCLUSIONS: Our findings suggest that the modified PCMH tool is feasible, and likely has sufficient performance variation to discriminate among clinics. Consistent with extant literature, clinics showed greatest room for improvement on access and continuity, supporting the tool's face validity. The modified PCMH tool may provide a powerful framework for evaluating chronic HIV care in RLS.

High rates of unplanned interruptions from HIV care early after antiretroviral therapy initiation in Nigeria.

BACKGROUND: Unplanned care interruption (UCI) challenges effective HIV treatment. We determined the frequency and risk factors for UCI in Nigeria. METHODS: We conducted a retrospective-cohort study of adults initiating antiretroviral therapy (ART) between January 2009 and December 2011. At censor, patients were defined as in care, UCI, or inactive. Associations between baseline factors and UCI rates were quantified using Poisson regression. RESULTS: Among 2,496 patients, 44 % remained in care, 35 % had ≥1 UCI, and 21 % became inactive. UCI rates were higher in the first year on ART (39/100PY), than the second (19/100PY), third (16/100PY), and fourth (14/100PY) years (p < 0.001). In multivariate analysis, baseline CD4 > 350/uL (IRR 3.21, p < 0.0001), being a student (IRR 1.95, p < 0.0001), and less education (IRR 1.58, p = 0.001) increased risk for UCI. Fifty-five percent of patients with UCI and viral load data had HIV viral load > 1,000 copies/ml upon return to care. DISCUSSION: UCI were observed in over one-third of patients treated, and were most common in the first year on ART. High baseline CD4 count at ART initiation was the greatest predictor of subsequent UCI. CONCLUSIONS: Interventions focused on the first year on ART are needed to improve continuity of HIV care.

The impact of user fees on uptake of HIV services and adherence to HIV treatment: Findings from a large HIV program in Nigeria.

BACKGROUND: Global HIV funding cutbacks have been accompanied by the adoption of user fees to address funding gaps in treatment programs. Our objective was to assess the impact of user fees on HIV care utilization and medication adherence in Nigeria. METHODS: We conducted a retrospective analysis of patients enrolled in care before (October 2012-September 2013) and after (October 2014-September 2015) the introduction of user fees in a Nigerian clinic. We assessed pre- vs. post-user fee patient characteristics and enrollment trends, and determined risk of care interruption, loss to follow-up, and optimal medication adherence. RESULTS: After fees were instituted, there was a 66% decline in patient enrollment and 75% decline in number of ART doses dispensed. There was no difference in the proportion of female clients (64% vs 63%, p = 0.46), average age (36 vs. 37 years, p = 0.15), or median baseline CD4 (220/ul vs. 222/uL, p = 0.24) in pre- and post-fee cohorts. There was an increase in clients employed and/or had tertiary education (24% vs. 32%, p<0.001). Compared to pre-fee patients, the post-fee period had a 48% decreased risk of care interruption (aRR = 0.52, 95%CI:0.39-0.69), 22% decreased LTFU risk (aRR = 0.64, 95%CI:0.96), and 27% decreased odds of optimal medication adherence (aOR = 0.7, 3 95%CI 0.59-0.89). CONCLUSIONS: Patients enrolled in care after introduction of user fees in Nigeria were more likely to be educated or employed, and effectively retained in care after starting ART. However, fees were accompanied by a drastic reduction in new patient enrollment, suggesting that many patients may have been marginalized from HIV care.

Effect of Baseline Symptom Manifestations on Retention in Care and Treatment among HIV-Infected Patients in Nigeria.

BACKGROUND: Symptom management is an important component of HIV care. But symptom patterns and how they affect engagement with HIV care and treatment services have not been adequately explored in the era of increased HIV treatment scale-up. We investigated the relationship between symptom patterns among people living with HIV (PLHIV) and 12 months retention in care, within the context of other clinical and demographic characteristics. METHODS: Retrospective cohort analysis of 5114 PLHIV receiving care within a large HIV treatment program in Nigeria. We assessed the prevalence and burden of baseline symptoms reported during routine clinic visits from January 2015 to December 2017. Multivariable regression was used to identify relationships between 12-month retention and symptom dimensions (prevalence and burden) while controlling for demographic and other clinical variables. RESULTS: Increasing symptom burden was associated with higher likelihood of retention at 12 months (adjusted odds ratio [aOR] = 1.19 [95% confidence interval, CI: 1.09-1.29]; P < .001) as was the reporting of skin rashes/itching symptom (aOR = 2.59 [95% CI: 1.65-4.09]; P < .001). Likelihood of retention reduced with increasing World Health Organization (WHO) Clinical staging, with CD4 ≥500 cells/mL and self-reported heterosexual mode of HIV transmission. Conclusions: Symptom dimensions and standardized clinical/immunological measures both predicted retention in care, but effects differed in magnitude and direction. Standardized clinical/immunological measures in HIV care (eg, WHO clinical staging and CD4 count categories) can mask important differences in how PLHIVs experience symptoms and, therefore, their engagement with HIV care and treatment. Symptom management strategies are required alongside antiretroviral treatment to improve outcomes among PLHIV, including retention in care.

High Medication Possession Ratios Associated With Greater Risk of Virologic Failure Among Youth Compared With Adults in a Nigerian Cohort.

BACKGROUND: Medication possession ratio (MPR) is widely used as a measure of adherence to antiretroviral therapy (ART). Many adolescents and young adults (AYA) experience ART adherence challenges. Our objective was to determine whether the relationship between MPR and virologic failure (VF) is consistent between AYA and older adults in Nigeria. METHODS: We conducted a retrospective study of AYA (aged 15-25 years) and adults (aged >25 years) who initiated ART between January 2009 and December 2012 at 10 university-affiliated HIV clinics in Nigeria. We used multivariate generalized linear models to assess the relationship between age, MPR (ART doses dispensed)/(days since ART initiation), and risk of VF (HIV RNA >1000 copies/mL) in the 1st year on ART. RESULTS: The cohort included 1508 AYA and 11,376 older adults. VF was more common in AYA than older adults (30% vs. 24% P < 0.01). Overall, 74% of patients had optimal, 16% suboptimal, and 9% poor adherence (MPR >94%, 80%-94%, and <80%, respectively). AYA attended fewer pharmacy-only visits than older adults (5 vs. 6, P < 0.001). Higher MPR was associated with decreased rate of VF (80%-94%, accounting rate of return 0.57; >94% accounting rate of return 0.43, P < 0.001 vs. MPR <80%). Among those with optimal adherence by MPR, 26% of AYA had VF, a risk that was 20% higher than for older adults with optimal adherence (P < 0.001). CONCLUSIONS: In this Nigerian cohort, MPRs were high overall, and there was a strong association between low MPR and risk of VF. Nonetheless, 26% of AYA with high MPRs still had VF. Understanding the discrepancy between MPR and viral suppression in AYA is an important priority.

Impact of Unplanned Care Interruption on CD4 Response Early After ART Initiation in a Nigerian Cohort.

The authors conducted a retrospective cohort study of unplanned care interruption (UCI) among adults initiating antiretroviral therapy (ART) from 2009 to 2011 in a Nigerian clinic. The authors used repeated measures regression to model the impact of UCI on CD4 count upon return to care and rate of CD4 change on ART. Among 2496 patients, 83% had 0, 15% had 1, and 2% had ≥2 UCIs. Mean baseline CD4 for those with 0, 1, or ≥2 UCIs was 228/cells/mm3, 355/cells/mm3, and 392/cells/mm3 ( P < .0001), respectively. The UCI was associated with a 62 CD4 cells/mm3 decrease (95% confidence interval [CI]: -78 to -45) at next measurement. In months 1 to 6 on ART, patients with 0 UCI gained 10 cells/µL/mo (95% CI: 7-4). Those with 1 and ≥2 UCIs lost 2 and 5 cells/µL/mo (95% CI: -18 to 13 and -26 to 16). Patients with UCI did not recover from early CD4 losses associated with UCI. Preventing UCI is critical to maximize benefits of ART.

Age Matters: Increased Risk of Inconsistent HIV Care and Viremia Among Adolescents and Young Adults on Antiretroviral Therapy in Nigeria.

PURPOSE: Interruptions in HIV care are a major cause of morbidity and mortality, particularly in resource-limited settings. We compared engagement in care and virologic outcomes between HIV-infected adolescents and young adults (AYA) and older adults (OA) one year after starting antiretroviral therapy (ART) in Nigeria. METHODS: We conducted a retrospective cohort study of AYA (15-24 years) and OA (>24 years) who initiated ART from 2009-2011. We used negative binomial regression to model the risk of inconsistent care and viremia (HIV RNA >1,000 copies/mL) among AYA and OA in the first year on ART. Regular care included monthly ART pickup and 3-monthly clinical visits. Patients with ≤3 months between consecutive visits were considered in care. Those with inconsistent care had >3 months between consecutive visits. RESULTS: The cohort included 354 AYA and 2,140 OA. More AYA than OA were female (89% vs. 65%, p < .001). Median baseline CD4 was 252/µL in AYA and 204/µL in OA (p = .002). More AYA had inconsistent care than OA (55% vs. 47%, p = .001). Adjusting for sex, baseline CD4, and education, AYA had a greater risk of inconsistent care than OA (Relative Risk [RR]: 1.15, p = .008). Among those in care after one year on ART, viremia was more common in AYA than OA (40% vs. 26% p = .003, RR: 1.53, p = .002). CONCLUSIONS: In a Nigerian cohort, AYA were at increased risk for inconsistent HIV care. Of patients remaining in care, youth was the only independent predictor of viremia at 1 year. Youth-friendly models of HIV care are needed to optimize health outcomes.

Treatment outcomes in a decentralized antiretroviral therapy program: a comparison of two levels of care in north central Nigeria.

Background. Decentralization of antiretroviral therapy (ART) services is a key strategy to achieving universal access to treatment for people living with HIV/AIDS. Our objective was to assess clinical and laboratory outcomes within a decentralized program in Nigeria. Methods. Using a tiered hub-and-spoke model to decentralize services, a tertiary hospital scaled down services to 13 secondary-level hospitals using national and program guidelines. We obtained sociodemographic, clinical, and immunovirologic data on previously antiretroviral drug naïve patients aged ≥15 years that received HAART for at least 6 months and compared treatment outcomes between the prime and satellite sites. Results. Out of 7,747 patients, 3729 (48.1%) were enrolled at the satellites while on HAART, prime site patients achieved better immune reconstitution based on CD4+ cell counts at 12 (P < 0.001) and 24 weeks (P < 0.001) with similar responses at 48 weeks (P = 0.11) and higher rates of viral suppression (<400 c/mL) at 12 (P < 0.001) and 48 weeks (P = 0.03), but similar responses at 24 weeks (P = 0.21). Mortality was 2.3% versus 5.0% (P < 0.001) at prime and satellite sites, while transfer rate was 8.7% versus 5.5% (P = 0.001) at prime and satellites. Conclusion. ART decentralization is feasible in resource-limited settings, but efforts have to be intensified to maintain good quality of care.
