Item Caregiver socioemotional health as a determinant of child well-being in school-aged and adolescent Ugandan children with and without perinatal HIV exposure(John Wiley & Sons Ltd, 2019) Webster, Kyle; Bruyn, Miko; Zalwango, Sarah; Sikorskii, Alla; Barkin, Jennifer; Familiar-Lopez, Itziar; Musoke, Philippa; Giordani, Bruno; Boivin, Michael; Ezeamama, Amara E.Caregiver socio-emotional attributes are major determinants of child well-being. This investigation in vulnerable school-aged Ugandan children estimates relationships between children’s well-being and their caregiver’s anxiety, depression and social support. methods Perinatally HIV-infected, HIV-exposed uninfected and HIV-unexposed Ugandan children and their caregivers were enrolled. Perinatal HIV status was determined by 18 months of age using DNA-polymerase chain-reaction test; status was confirmed via HIV rapid diagnostic test when children were 6–18 years old. Five indicators of child well-being (distress, hopelessness, positive future orientation, esteem and quality of life (QOL)) and caregivers’ socioemotional status (depressive symptoms, anxiety and social support) were measured using validated, culturally adapted and translated instruments. Categories based on tertiles of each caregiver psychosocial indicator were defined. Linear regression analyses estimated percent differences (b) and corresponding 95% confidence intervals (CI) for child well-being in relation to caregiver’s psychosocial status results As per tertile increment, caregiver anxiety was associated with 2.7% higher distress (95% CI:0.2%, 5.3%) and lower self esteem/QOL (b = 1.3%/ 2.6%; 95%CI: 5.0%,-0.2%) in their children. Child distress/hopelessness increased (b = 3.3%/7.6%; 95%CI:0.4%, 14.7%) and self-esteem/QOL decreased 2.3% (b = 2.3%/ 4.4%; 95%CI: 7.2%, 1.3%) as per tertile increment in caregiver depression. Higher caregiver social support was associated with lower distress and higher positive outlook (b = 3%; 95%CI:1.4%, 4.5%) in their children. HIV-infected/exposed children had most caregiver depression-related QOL deficit (b = 5.2%/ 6.8%; 95%CI: 12.4%, 0.2%) and HIV-unexposed children had most caregiver social support-related enhancements in positive outlook (b=4.5%; 95%CI:1.9%, 7.1%). conclusions Caregiver anxiety, depressive symptoms and low social support were associated with worse well-being in school-aged and adolescent children. Improvement of caregiver mental health and strengthening caregiver social support systems may be a viable strategy for improving well-being of vulnerable children and adolescents in this setting.Item Computerized Cognitive Rehabilitation Training for Ugandan Seniors Living with HIV: A Validation Study(Journal of Clinical Medicine, 2020) Ezeamama, Amara E.; Sikorskii, Alla; Sankar, Parvathy R.; Nakasujja, Noeline; Ssonko, Michael; Kaminski, Norbert E.; Guwatudde, David; Boivin, Michael J.; Giordani, BrunoThe feasibility, acceptability and preliminary efficacy of computerized cognitive rehabilitation therapy (CCRT) for mitigating neurocognitive decline was evaluated in African adults 50 years old. Eighty-one Ugandans with (n = 40) and without (n = 41) chronic human immunodeficiency viruses (HIV) were allocated CCRT—i.e., 20–45-min cognitive training sessions with culturally adapted video games delivered via Captain’s Log Software, or standard of care (SOC). Pre and post (i.e., 8-weeks later) intervention performance based neurocognitive tests, quality of life (QOL) and frailty related phenotype (FRP) were determined in all respondents. Multivariable linear regression estimated CCRT- vs. SOC-related di erences ( ) in neurocognitive batteries, QOL and FRP. E ect sizes (ES) for estimated were calculated. CCRT protocol was completed by 92.8% of persons allocated to it. Regardless of HIV status, CCRT was associated with higher performance in learning tests than SOC—interference list ( = 1.00, 95%CI: (0.02, 1.98); ES = 0.43) and delayed recall ( = 1.04, 95%CI: (0.06, 2.02); ES = 0.47). CCRT e ect on verbal fluency was clinically important (ES = 0.38), but statistical significance was not reached ( = 1.25, 95%CI: (0.09, 2.58)). Among HIV-positive adults, clinically important post-CCRT improvements were noted for immediate recall (ES = 0.69), working memory (ES = 0.51), verbal fluency (ES = 0.51), and timed gait (ES = 0.44) tasks. Among HIV-negative adults, CCRT resulted in moderate post-intervention improvement in learning tests (ES = 0.45) and large decline in FRP (ES = 0.71), without a positive e ect on simple attention and visuomotor coordination tasks. CCRT intervention is feasible among older Ugandan adults with potential benefit for learning and verbal fluency tests regardless of HIV status and lowering FRP in HIV-negative older adults.Item Depressive and Anxiety Symptoms Predict Sustained Quality of Life Deficits in HIV-Positive Ugandan Adults Despite Antiretroviral Therapy(Medicine, 2016) Ezeamama, Amara E.; Woolfork, Makhabele N.; Guwatudde, David; Bagenda, Danstan; Manabe, Yukari C.; Fawzi, Wafaie W.; Fawzi, Mary C. Smith: The impact of psychosocial status at onset of antiretroviral therapy on changes in quality of life (QOL) and subjectively rated health (SRH) among adults on ART in resource-limited settings is poorly understood. Therefore, we evaluate the association between stigma, anxiety, depression, and social support and change in QOL and SRH in HIV-infected Ugandan adults during an 18-month period. Psychosocial indicators were assessed at enrollment using structured questionnaires. QOL and SRH measures were assessed at months 0, 6, 12, and 18 using the Medical Outcomes Survey-HIV. Linear mixed models determined risk estimated differences in QOL and SRH in relation to quartiles of each psychosocial status indicator. Repeated measures generalized estimating equations modeling was implemented to assess differences inlikelihood ofimproved versus nonimproved SRH during follow-up. QOL scores and SRH improved significantly for all participants over 18 months (P< 0.0001). The gain in QOL increased dose-dependently as baseline depressive symptoms (time depression P< 0.001) and anxiety levels (time anxiety P< 0.001) declined. Lower social support was associated with worse QOL at baseline (P¼ 0.0005) but QOL improvement during follow-up was not dependent on baseline level of social support (time social support P¼ 0.8943) or number of stigmatizing experiences (time stigma P¼ 0.8662). Psychosocial determinants did not predict changes in SRH in this study. High levels of depression and anxiety symptoms at HAART initiation predicts lower gains in QOL for HIV-positive patients for as long as 18 months. Long-term QOL improvements in HIV-infected adults may be enhanced by implementation of psychosocial interventions to reduce depression and anxiety in HIV-infected adultsItem Dietary Micronutrients and Gender, Body Mass Index and Viral Suppression Among HIV-Infected Patients in Kampala, Uganda(International Journal of Maternal and Child Health and AIDS, 2020) Isabirye, Nathan; Ezeamama, Amara E.; Kyeyune-Bakyayita, Rachel; Bagenda, Danstan; Fawzi, Wafaie W.; Guwatudde, DavidHIV/AIDS is a hallmark of immune suppression. Micronutrient deficiencies in diet and recurrent opportunistic infections play major roles in the lives of people living with HIV. Although benefits of providing adequate diet to HIV positive persons are well documented, the demand for key elements still remain unclear in particular settings, especially in low and middle-income countries. Methods: This was a cross sectional analysis of baseline data collected from HIV-infected adults initiating antiretroviral therapy, and who were enrolled in a multivitamin supplementation trial. A food frequency questionnaire was used and intake were obtained as a product of quantities consumed. Adequacy was calculated as the proportion of Recommended Dietary Allowances (RDA). A chi square test and logistic regression analysis were used at p-value 0.05 to show significant associations. Results: Mean intakes were above minimum requirements for analyzed micronutrients with the exception of Calcium and Iron. Participants who met RDA intakes were as follows: highest (≥ 80%) for Magnesium, Selenium, Zinc and Vitamins B2, B6, B9, C and E; moderate (50% to <80%) for Vitamins B3, and A; and lowest (≤50%) for Iron (30%), Calcium (14.9%), Vitamins B12 and B1. Gender differences in met RDA were observed for Iron, Selenium, Zinc, Vitamins A, B1, B3 and E. In multivariable analyses, nutritional status and CD4 count had no influence on meeting RDA for majority of micronutrients such as magnesium, Selenium, B class vitamins (B1, B2, B3, B6, B9, B12), vitamin (A, C, and E), Zinc and Calcium, but not including iron. Conclusion and Global Health Implications: Diets consumed by the study participants were low in most protective nutrients (Iron, Calcium, Zinc, Vitamin A, B1, B3, and B12). This deficiency was more common among females than males, and irrespective of BMI or CD 4 count. Findings warrant further investigation on the impact and cost implications for suplementation interventions that target the elements lacking in the diets of people living with HIV in similar low-resourced settings.Item The effect of standard dose multivitamin supplementation on disease progression in HIV infected adults initiating HAART: a randomized double blind placebo-controlled trial in Uganda(BMC infectious diseases, 2015) Guwatudde, David; Wang, Molin; Ezeamama, Amara E.; Bagenda, Danstan; Kyeyune, Rachel; Wamani, Henry; Manabe, Yukari C.; Fawzi, Wafaie W.Efficacy trials investigating the effect of multivitamin (MV) supplementations among patients on Highly Active Antiretroviral Therapy (HAART) have so far been inconclusive. We conducted a randomized, double blind, placebo controlled trial to determine the effect of one recommended daily allowance (RDA) of MV supplementation on disease progression in patients initiating HAART. Methods: Eligible subjects were randomized to receive placebo or MV supplementation including vitamins Bcomplex, C and E. Participants were followed for up to 18 months. Primary endpoints were: change in CD4 cell count, weight and quality of life (QoL). Secondary endpoints were: i) development of a new or recurrent HIV disease progression event, including all-cause mortality; ii) switching from first- to second-line antiretroviral therapy (ART); and iii) occurrence of an adverse event. Intent-to-treat analysis, using linear regression mixed effects models were used to compare changes over time in the primary endpoints between the study arms. Kaplan-Meier time-toevent analysis and the log-rank test was used to compare HIV disease progression events and all-cause mortality. Results: Four hundred participants were randomized, 200 onto MV and 200 onto placebo. By month 18, the average change in CD4 cell count in the MV arm was 141 cells/uL compared to 147 cells/uL in the placebo arm, a mean difference of −6 · 17 [95 % CI −29 · 3, 16 · 9]. The average change in weight in the MV arm was 3 · 9 kg compared to 3 · 3 kg in the placebo arm, a mean difference of 0 · 54 [95 % CI −0 · 40, 1 · 48]; whereas average change in QoL scores in the MV arm was 6 · 8 compared to 8 · 8 in the placebo arm, a mean difference of −2.16 [95 % CI −4 · 59,0 · 27]. No significant differences were observed in these primary endpoints, or in occurrence of adverse events between the trial arms. Conclusions: One RDA of MV supplementation was safe but did not have an effect on indicators of disease progression among HIV infected adults initiating HAART.Item Evolution of Anemia Types During Antiretroviral Therapy—Implications for Treatment Outcomes and Quality of Life Among HIV-Infected Adults(Nutrients, 2019) Ezeamama, Amara E.; Sikorskii, Alla; Bajwa, Ramanpreet K.; Tuke, Robert; Kyeyune, Rachel B.; Fenton, Jenifer I.; Guwatudde, David; Fawzi, WafaieW.This study examined whether the type of anemia in persons living with HIV/AIDS (PLWHA) changed from the beginning of highly antiretroviral therapy (HAART) and had implications for treatment outcomes and quality of life (QOL). If present, the anemia-type was defined as microcytic, macrocytic or anemia of chronic disease (ACD) at study months 0, 6, 12, and 18. Multinomial logistic regression quantified sociodemographic and HIV-treatment factors associated with incident microcytic anemia or ACD over 18 months. Repeated measures linear regression models estimated the anemia-type associated change in the CD4 cell-count, QOL, body mass index (BMI) and frailty over 18 months. Cox proportional hazard models estimated associations between anemia-type and time to (a) gain at least 100 CD4 cells/L and (b) hospitalization/death. Analyses were implemented in Statistical Analysis Software (v.9.4) from which odds ratios (ORs) mean differences ( ) and corresponding 95% confidence intervals (CI) were estimated. At enrollment, ACD, macrocytic and microcytic anemia was present in 36.8% (n = 147), 11.3% (n = 45) and 9.5% (n = 38), respectively with 42% (n = 170) anemia-free. By the study end, only 23% (n = 115) were without anemia. Among the 251 with anemia at the study end, 53.3% (n = 195) had macrocytic anemia, 12.8% (n = 47) had ACD and 2.5% (n = 9) had microcytic anemia. Incident macrocytic anemia was positively associated with baseline hyperferritinemia (OR = 1.85, 95%CI: 1.03–3.32), inversely associated with wealth (OR = 0.87, 95%CI: 0.67–1.03) and inversely associated with efavirenz-containing HAART (OR = 0.42, 95%CI: 0.21–0.85). ACD incidence decreased by 53% (95%CI: 0.27–0.79) per 100 cells/L increase in baseline CD4-cell count and decreased by 90% (95%CI: 0.01,0.87) among adults treated with nevirapine-containing HAART. ACD was associated with a lower BMI at months 6 ( = 0.33, 95% CI: 0.64, 0.01) and 12 ( = 0.41, 95%CI: 0.73, 0.09), with lower QOL ( = 3.2, 95%CI: 5.94, 0.53) at month 12 and with elevated frailty ( = 1.2; 95%CI: 0.46, 1.86) at month 12. Macrocytic anemia did not predict a post-enrollment change in CD4, BMI or QOL during follow-up. However, the time to gain 100 CD4 cells/L was 43% slower (p < 0.05) and the frailty was higher at month 12 for PLWHA with the baseline or sustained macrocytic vs. no anemia. A substantial decline in ACD and microcytic anemia occurred in tandem with large increase in the macrocytic anemia over 18 months on HAART. Interventions to mitigate all anemia—particularly ACD, is expected to improve the immune recovery rate, lower frailty, and enhanced QOL.Item Four Degrees of Separation: Social Contacts and Health Providers Influence the Steps to Final Diagnosis of Active Tuberculosis Patients in Urban Uganda(BMC infectious diseases, 2015) Sekandi, Juliet N.; Zalwango, Sarah; Martinez, Leonardo; Handel, Andreas; Kakaire, Robert; Nkwata, Allan K.; Ezeamama, Amara E.; Kiwanuka, Noah; Whalen, Christopher C.Delay in tuberculosis (TB) diagnosis adversely affects patients’ outcomes and prolongs transmission in the community. The influence of social contacts on steps taken by active pulmonary TB patients to seek a diagnosis has not been well examined. Methods: A retrospective study design was use to enroll TB patients on treatment for 3 months or less and aged ≥18 years from 3 public clinics in Kampala, Uganda, from March to July 2014. Social network analysis was used to collect information about social contacts and health providers visited by patients to measure the number of steps and time between onset of symptoms and final diagnosis of TB. Results: Of 294 TB patients, 58 % were male and median age was 30 (IQR: 24–38) years. The median number of steps was 4 (IQR: 3, 7) corresponding to 70 (IQR: 28,140) days to diagnosis. New patients had more steps and time to diagnosis compared retreatment patients (5 vs. 3, P < 0.0001; 84 vs. 46 days P < 0.0001). Fifty-eight percent of patients first contacted persons in their social network. The first step to initiate seeking care accounted for 41 % of the patients’ time to diagnosis while visits to non-TB providers and TB providers (without a TB diagnosis) accounted for 34 % and 11 % respectively. New TB patients vs. retreatment (HR: 0.66, 95 % CI; 1.11, 1.99), those who first contacted a non-TB health provider vs. contacting social network (HR: 0.72 95 % CI; 0.55, 0.95) and HIV seronegative vs. seropositive patients (HR: 0.70, 95 % CI; 0.53, 0.92) had a significantly lower likelihood of a timely final diagnosis. Conclusions: There were four degrees of separation between the onset of symptoms in a TB patient and a final diagnosis. Both social and provider networks of patients influenced the diagnostic pathways. Most delays occurred in the first step which represents decisions to seek help, and through interactions with non-TB health providers. TB control programs should strengthen education and active screening in the community and in health care settings to ensure timely diagnosis of TB.Item In utero/peripartum antiretroviral therapy exposure and mental health outcomes at 8–18 years old: A longitudinal comparative study of children with perinatally acquired HIV, children perinatally HIV exposed but uninfected, and children unexposed uninfected from Uganda(Wiley Subscription Services, Inc, 2024-04) Coventry, Audrey; Sikorskii, Alla; Zalwango, Sarah K.; Familiar‐Lopez, Itziar; Cardino, Vanessa N.; Giordani, Bruno; Ezeamama, Amara E.Abstract In utero/peripartum antiretroviral therapy (IPA) exposure type was examined in relationship to mental health symptoms among 577 children with perinatally acquired HIV (CPHIV), children perinatally HIV exposed but uninfected (CHEU), and children HIV unexposed uninfected (CHUU). IPA exposure was categorized for CPHIV and CHEU as none, single-dose nevirapine with or without zidovudine (sdNVP±AZT), sdNVP+AZT+lamivudine (3TC), or combination antiretroviral therapy (cART). Anxiety and depressive symptoms were reported at baseline, 6-, and 12-month follow-up per behavioral assessment system for children. Multivariable linear mixed models were used to estimate differences (b) with 95% confidence intervals (95% CI) for IPA exposure types versus CHEU without IPA exposure. Depressive and anxiety symptoms were lower in CHUU relative to CHEU and CPHIV but did not differ between CPHIV and CHEU. CHEU with sdNVP±AZT exposure had greater anxiety (b = 0.51, 95% CI: [0.06, 0.96]) and depressive symptoms (b = 0.48, 95% CI: [0.07, 0.89]) than CHEU without IPA exposure. CHEU with sdNVP+AZT+3TC exposure had higher anxiety (b = 0.0.45, 95% CI: [0.03, 0.86]) and depressive symptoms (b = 0.72, 95% CI: [0.27, 1.17]) versus CHEU without IPA exposure. Depressive and anxiety symptoms were not different for CHEU and CPHIV exposed to cART (b = 0.12-0.60, 95% CI: [-0.41, 1.30]) and CHEU and CHUU (b = -0.04 to 0.08, 95% CI: [-0.24, 0.29]) without IPA exposure. Among CHEU, peripartum sdNVP±AZT and sdNVP+AZT+3TC but not cART compared to no IPA exposure was associated with clinically important elevations in anxiety and depressive symptoms. Monitoring of mental health trajectory of HIV-affected children considering IPA is needed to inform mental health interventions. Patient Contribution: Caregivers and their dependents provided consent for participation and collaborated with study team to identify mutually convenient times for protocol implementation.Item Multivitamin supplementation in HIV infected adults initiating antiretroviral therapy in Uganda: the protocol for a randomized double blinded placebo controlled efficacy trial(BMC Infectious Diseases, 2012) Guwatudde, David; Ezeamama, Amara E.; Bagenda, Danstan; Wabwire-Mangen, Fred; Wamani, Henry; Mugusi, Ferdinand; Spiegelman, Donna; Kyeyune, Rachel; Wang, Molin; Manabe, Yukari C.; Fawzi, Wafaie W.Use of multivitamin supplements during the pre-HAART era has been found to reduce viral load, enhance immune response, and generally improve clinical outcomes among HIV-infected adults. However, immune reconstitution is incomplete and significant mortality and opportunistic infections occur in spite of HAART. There is insufficient research information on whether multivitamin supplementation may be beneficial as adjunct therapy for HIV-infected individuals taking HAART. We propose to evaluate the efficacy of a single recommended daily allowance (RDA) of micronutrients (including vitamins B-complex, C, and E) in slowing disease progression among HIV-infected adults receiving HAART in Uganda. Methods/Design: We are using a randomized, double-blind, placebo-controlled trial study design. Eligible patients are HIV-positive adults aged at least 18 years, and are randomized to receive either a placebo; or multivitamins that include a single RDA of the following vitamins: 1.4 mg B1, 1.4 mg B2, 1.9 mg B6, 2.6 mcg B12, 18 mg niacin, 70 mg C, 10 mg E, and 0.4 mg folic acid. Participants are followed for up to 18 months with evaluations at baseline, 6, 12 and 18 months. The study is primarily powered to examine the effects on immune reconstitution, weight gain, and quality of life. In addition, we will examine the effects on other secondary outcomes including the risks of development of new or recurrent disease progression event, including all-cause mortality; ARV regimen change from first- to second-line therapy; and other adverse events as indicated by incident peripheral neuropathy, severe anemia, or diarrhea. Discussions: The conduct of this trial provides an opportunity to evaluate the potential benefits of this affordable adjunct therapy (multivitamin supplementation) among HIV-infected adults receiving HAART in a developing country setting.Item Perinatal HIV Status and Executive Function During School-Age and Adolescence(Wolters Kluwer Health, 2016) Ezeamama, Amara E.; Kizza, Florence N.; Zalwango, Sarah K.; Nkwata, Allan K.; Zhang, Ming; Rivera, Mariana L.; Sekandi, Juliet N.; Kakaire, Robert; Kiwanuka, Noah; Whalen, Christopher C.The aim of this study was to determine whether perinatal HIV infection (PHIV), HIV-exposed uninfected (PHEU) versus HIVunexposed (PHU) status predicted long-term executive function (EF) deficit in school-aged Ugandan children. Perinatal HIV status was determined by 18 months via DNA polymerase chain reaction test and confirmed at cognitive assessment between 6 and 18 years using HIV rapid-diagnostic test. Primary outcome is child EF measured using behavior-rating inventory of executive function questionnaire across 8 subscales summed to derive the global executive composite (GEC).Item Plasma n-6 Fatty Acid Levels Are Associated With CD4 Cell Counts, Hospitalization, and Mortality in HIV-Infected Patients(Journal of acquired immune deficiency syndromes, 2016) Kabagambe, Edmond K.; Ezeamama, Amara E.; Guwatudde, David; Campos, Hannia; Fawzi, Wafaie W.Fatty acids, including n-6 series, modulate immune function, but their effect on CD4 cell counts, death, or hospitalization in HIV-infected patients on antiretroviral therapy is unknown. Methods: In a randomized trial for effects of multivitamins in HIVinfected patients in Uganda, we used gas chromatography to measure plasma n-6 fatty acids at baseline; determined CD4 counts at baseline, 3, 6, 12, and 18 months; and recorded hospitalization or death events. The associations of fatty acids with CD4 counts and events were analyzed using repeated-measures analysis of variance and Cox regression, respectively. Results: Among 297 patients with fatty acids measurements, 16 patients died and 69 were hospitalized within 18 months. Except for linoleic acid, n-6 fatty acids levels were positively associated with CD4 counts at baseline but not during follow-up. In models that included all 5 major n-6 fatty acids, age; sex; body mass index; anemia status; use of antiretroviral therapy, multivitamin supplements, and alcohol; and the risk of death or hospitalization decreased significantly with an increase in linoleic acid and gamma-linolenic acid levels, whereas associations for dihomo-gamma-linolenic acid, arachidonic acid, and aolrenic acid were null. The hazard ratios (95% confidence intervals) per 1 SD increase in linoleic acid and gammalinolenic acid were 0.73 (0.56–0.94) and 0.51 (0.36–0.72), respectively. Gamma-linolenic acid remained significant (hazard ratio = 0.51; 95% confidence interval: 0.35 to 0.68) after further adjustment for other plasma fatty acids. Conclusions: Lower levels of gamma-linolenic acid are associated with lower CD4 counts and an increased risk of death or hospitalization. These results suggest a potential for using n-6 fatty acids to improve outcomes from antiretroviral therapy.Item Prevalence and correlates of cytopenias in HIV-infected adults initiating highly active antiretroviral therapy in Uganda(BMC Infectious Diseases, 2014) Kyeyune, Rachel; Saathoff, Elmar; Ezeamama, Amara E.; Löscher, Thomas; Fawzi, Wafaie; Guwatudde, DavidCytopenias are the most common HIV-associated hematological abnormality. Cytopenias have been associated with several factors including sex, race/ethnicity, geographical location and comorbidities such as tuberculosis, hepatitis B infection, fever and oral candidiasis. Cytopenias become more prevalent as HIV progresses and are often fatal. Data from resource-limited settings about the prevalence and correlates of cytopenia are limited. Therefore we conducted this cross-sectional study to assess the prevalence and correlates of cytopenia among adult AIDS patients at initiation of HAART in Uganda. Methods: 400 HIV-infected subjects who were HAART-naïve or on HAART for ≤ 6 months were enrolled into the Multivitamins, HAART and HIV/AIDS Trial. Anemia was defined according to WHO guidelines as any hemoglobin concentration < 12 g/dl for non-pregnant females and < 13 g/dl for males. Leucopenia and thrombocytopenia were defined using study site laboratory reference ranges for lack of generally accepted definitions for these 2 cell lines as leucopenia if white blood cell count < 2.75 × 109 cells/litre and thrombocytopenia if platelets < 125 × 109 cells/litre for females and < 156 × 109 cells/litre for males. Univariate and bivariate analyses were done to describe the patient population and log-binomial regression was used to quantify the correlates of cytopenia. Results: Sixty five percent of the 400 subjects had at least one form of cytopenia. Anemia occurred in 47.8%, leucopenia in 24.3%, thrombocytopenia in 8.3%, bicytopenia in 21.9% and only 2 had a pancytopenia. Cytopenia was more prevalent in females (prevalence ratio [PR]:1.33, 95% confidence interval [CI]:1.12-1.59); CD4 count category 50 to <200 (PR: 0.75, 95% CI: 0.64 -0.88) and CD4 count category 200 to <350 (PR: 0.74, 95% CI: 0.59 - 0.92) compared to CD4 count category <50; normal BMI (PR: 0.82, 95% CI:0.68-1.00) and overweight BMI (PR: 0.64, 95% CI:0.50- 0.82) compared to underweight BMI and those with a history or presence of oral candidiasis. Conclusions: Cytopenias are a frequent complication in HIV-infected adults at initiation of HAART in Uganda. The presence of any cytopenia was associated with female sex, decreasing CD4 count and decreasing body mass index. Prospective studies in resource-limited settings on the trend in HIV-related cytopenias are needed.Item Psychosocial Adjustment in Ugandan Children: Coping With Human Immunodeficiency Virus Exposure, Lifetime Adversity, and Importance of Social Support(New Directions for Child and Adolescent Development, 2020) Tuke, Robert; Sikorskii, Alla; Zalwango, Sarah K.; Webster, Kyle D.; Ismail, Alexander; Pobee, Ruth A.; Barkin, Jennifer L.; Boivin, Michael J.; Giordani, Bruno; Ezeamama, Amara E.Cumulative lifetime adversity and social support were investigated as determinants of psychosocial adjustment (esteem, distress, hopefulness, positive outlook/ future aspirations, and sense of purpose) over 12months in 6–10-years-old HIV-infected, HIV-exposed uninfected and HIV-unexposed uninfected children from Uganda. Each determinant and psychosocial adjustment indicator was self-reported using standardized questionnaires administered at baseline, 6, and 12 months. Linear mixed effects models were used to relate time-varying lifetime adversity and social support to psychosocial adjustment over 12 months. Regardless of HIV status, higher adversity predicted lower esteem (coefficient b = −2.98, 95% confidence interval (CI): [−4.62, −1.35]) and increased distress (b =3.96, 95% CI: [1.29, 6.62]) but was not associated with hopefulness, positive outlook or sense of purpose. Low social support predicted higher distress (b =9.05, 95% CI: [7.36, 10.73]), lower positive outlookItem Serum n-6 Fatty Acids are Positively Associated with Growth in 6-to-10-Year Old Ugandan Children Regardless of HIV Status—A Cross-Sectional Study(Nutrients, 2019) Jain, Raghav; Ezeamama, Amara E.; Sikorskii, Alla; Yakah, William; Zalwango, Sarah; Musoke, Philippa; Boivin, Michael J.; Fenton, Jenifer I.Fatty acids (FAs) are crucial in child growth and development. In Uganda, antiretroviral therapy (ART) has drastically reduced perinatal human immunodeficiency virus (HIV) infection of infants, however, the interplay of FAs, ART, and HIV in relation to child growth is not well understood. To investigate this, serum was collected from 240 children between 6–10 years old in Uganda and analyzed for FAs using gas-chromatography mass-spectrometry. HIV status and anthropometric measurements were taken, and relationships with FAs were assessed. No significant differences in growth parameters or serum FAs were found between HIV uninfected children with and without exposure to ART. HIV positive children had significantly lower height-for-age-z-scores (HAZ) than uninfected children (p < 0.001). HIV-positive children had higher arachidonic acid than uninfected children (p = 0.003). Total omega-6 FAs were significantly associated with HAZ regardless of HIV status (p = 0.035). Mean total omega-3 FAs (2.90%) were low in this population compared to other cohorts in Africa. These results provide reference serum FA values for 6–10-year-old children in Uganda and may be used to inform lipid supplementation programs to promote child growth. Future studies should investigate the relationships between child growth trajectories in relation to HIV status and serum FAs.

This study examines the thesis that deficits in SEA are related to VDI using longitudinal data from 254 children that are perinatally HIV-infected (PHIV), exposed-uninfected (HEU), or unexposed-uninfected (HUU). In utero/peripartum antiretroviral (IPA) exposure was established per medical record documentation of biological mother’s ART regimen in pregnancy. Four caregiver-reported age- and sex-standardized measures of SEA were obtained at months 0, 6, and 12 for dependent children aged 6–10 years: externalizing problems (EPC), internalizing problems (IPC), behavioral symptoms index (BSI), and adaptive skills index (ASI). VDI was highly prevalent (74%, n = 188), and its association with change in SEA measures over 12 months varied by HIV-status (VDI*HIV, all p-values < 0.03). There was further variation in relationship of vitamin-D to SEA by IPA among PHIV (for ASI, BSI, and EPC, vitamin-D*IPA, p-value ≤ 0.01) and HEU (for BSI and EPC, vitamin-D*IPA, p-value ≤ 0.04). Among HUU, BSI (β = −0.32, 95% CI: −0.50, −0.13), IPC (β = −0.28, 95% CI: −0.47, −0.09), and EPC (β = −0.20, 95% CI: −0.37, −0.02) all declined moderately per quartile increment in VD. Among PHIV, on the one hand higher vitamin D predicted ASI gains (moderate vs. low VD, β = 0.52, p = 0.002), but this protective association was absent for BSI, EPC, and IPC (β = 0.36–0.77, p < 0.05). In absence of IPA-exposure, increasing vitamin-D predicted declines in BSI and EPC (moderate vs. low Vitamin D, β = −0.56 to −0.71, p ≤ 0.02) among HEU. However, given IPA exposure among HEU, higher VDI predicted moderate elevation in BSI (β = 0.39, 95% CI: 0.00, 0.78) and IPC (β = 0.48, 95% CI: 0.05, 0.92). Interaction between VD and IPA exposure for SEA outcomes among HEU and PHIV children warrants further investigation. The vitamin-D associated SEA improvement among HUU and HEU without IPA exposure suggests vitamin-D supplementation may remediate behavioral and adaptive deficits in this groups. View Full-Text
