listen audio

Study Justification:
This study aimed to investigate the prevalence of HIV-associated encephalopathy (HIVE) in hospitalized infants in Mozambique who were not receiving antiretroviral therapy (ART). The neurodevelopmental impact of HIV infection in older children has been well-documented, but there is limited research on HIVE in infants. Understanding the prevalence and risk factors of HIVE in this population is crucial for improving diagnosis and providing appropriate care.
Highlights:
– The study found that 26% of the hospitalized infants with confirmed HIV infection were classified as presumptive HIVE.
– Delayed developmental milestones were observed in 67% of the patients, and the prevalence was significantly higher in the HIVE-positive group.
– Factors associated with HIVE included delayed or no maternal ART and the infant not receiving postnatal nevirapine prophylaxis.
– Thorough neurologic and developmental assessments can help identify HIV-infected infants, especially in settings without access to point-of-care virologic testing.
– Infants with HIVE require comprehensive care, including antiretroviral therapy and physical/occupational therapy.
Recommendations:
Based on the findings of this study, the following recommendations are suggested:
1. Improve access to antiretroviral therapy for HIV-infected infants, particularly those with risk factors for in-utero transmission.
2. Strengthen the implementation of postnatal nevirapine prophylaxis to reduce the risk of HIVE.
3. Enhance the capacity of pediatric wards to conduct thorough neurologic and developmental assessments for early identification of HIV-infected infants.
4. Provide comprehensive care for infants with HIVE, including antiretroviral therapy and physical/occupational therapy.
Key Role Players:
To address these recommendations, the involvement of the following key role players is essential:
1. Ministry of Health: Responsible for policy development and implementation.
2. Healthcare providers: Including pediatricians, nurses, and other healthcare professionals involved in the care of HIV-infected infants.

The strength of evidence for this abstract is 7 out of 10.
The evidence in the abstract is moderately strong. The study conducted a descriptive analysis of routine inpatient data from two central referral hospitals in Mozambique, which provides some evidence on the prevalence of HIV-associated encephalopathy (HIVE) in hospitalized infants. The study identified risk factors associated with HIVE and highlighted the importance of thorough neurologic and developmental assessments for HIV-infected infants. However, the study design is descriptive and does not include a control group or intervention, limiting the ability to establish causality. To improve the strength of the evidence, future studies could consider a prospective design with a control group and include interventions to evaluate the effectiveness of comprehensive care for infants with HIVE.

Introduction: The neurodevelopmental impact of HIV infection in older children has been well-described, with characterization of HIV-associated encephalopathy (HIVE) and associated cognitive defects. HIVE is relatively common in older children who were vertically infected. The sparse literature on HIVE in infants suggests that incidence may be up to 10% in the first year of life, but no studies were identified that specifically evaluated hospitalized infants. Methods: A descriptive study of routine inpatient data from two central referral hospitals in Mozambique was conducted. Inclusion criteria were infants with confirmed HIV infection aged <12 months, not on ART, admitted between 1 January 2019 and 30 June 2019. Presumptive HIVE was defined as having delayed developmental milestones in addition to microcephaly and/or pathological reflexes. Results: Seven out of 27 patients (26%) were classified as presumptive HIVE. Delayed milestones were seen in 18 patients (67%) and the prevalence was approximately two times higher in the HIVE (+) group across all milestone categories. Delayed or no maternal ART (p = 0.03) and the infant not having received postnatal nevirapine prophylaxis (p = 0.02) were significantly associated with HIVE. Conclusions: HIVE prevalence is high in ART naïve hospitalized infants, particularly in those with risk factors for in-utero transmission. Thorough neurologic and developmental assessments can help identify HIV-infected infants and can be of particular utility in pediatric wards without access to point-of-care virologic testing where presumptive HIV diagnosis is still needed. Infants with HIVE need comprehensive care that includes antiretroviral therapy and physical/occupational therapy.

Strengthening maternal HIV testing and treatment programs: Implementing comprehensive HIV testing and treatment programs for pregnant women can help identify and treat HIV-positive mothers early in their pregnancy. This can reduce the risk of vertical transmission to their infants and improve overall maternal health.

2. Enhancing antenatal care services: Improving access to antenatal care services can ensure that pregnant women receive regular check-ups, including HIV testing and counseling. This can help identify HIV-positive women and provide them with appropriate interventions and support throughout their pregnancy.

3. Promoting maternal ART adherence: Educating and supporting HIV-positive mothers to adhere to antiretroviral therapy (ART) can significantly reduce the risk of vertical transmission and improve maternal health outcomes. Innovative approaches such as mobile health technologies or community-based support groups can be explored to enhance ART adherence.

4. Implementing postnatal HIV prophylaxis: Ensuring that infants born to HIV-positive mothers receive appropriate postnatal nevirapine prophylaxis can further reduce the risk of vertical transmission. Strengthening healthcare systems to provide access to prophylactic medications and monitoring can be crucial in improving infant health outcomes.

5. Integrating neurologic and developmental assessments: Incorporating thorough neurologic and developmental assessments into routine pediatric care can help identify HIV-infected infants, including those with HIV-associated encephalopathy (HIVE). This can be particularly useful in settings where point-of-care virologic testing is not readily available. Early identification of HIVE can facilitate timely interventions and comprehensive care for affected infants.

6. Enhancing comprehensive care for infants with HIVE: Providing comprehensive care for infants with HIVE is essential. This includes not only antiretroviral therapy but also physical and occupational therapy to address neurodevelopmental delays. Strengthening healthcare systems to ensure access to these services can improve the long-term outcomes of HIV-infected infants.

By implementing these recommendations, access to maternal health can be improved, and innovative approaches can be developed to address the specific challenges faced in Mozambique and similar settings.
AI Innovations Methodology
To improve access to maternal health, here are a few potential recommendations:

1. Telemedicine and Mobile Health: Implementing telemedicine and mobile health solutions can help overcome geographical barriers and provide remote access to maternal health services. This can include virtual consultations, remote monitoring of vital signs, and educational resources delivered through mobile apps.

2. Community Health Workers: Training and deploying community health workers can improve access to maternal health services, especially in rural and underserved areas. These workers can provide basic prenatal care, health education, and referrals to healthcare facilities when necessary.

3. Maternal Health Vouchers: Introducing maternal health vouchers can help reduce financial barriers to accessing maternal healthcare. These vouchers can be distributed to pregnant women, allowing them to receive essential services such as antenatal care, skilled birth attendance, and postnatal care free of charge or at a reduced cost.

4. Transportation Support: Lack of transportation is a significant barrier to accessing maternal health services, particularly in remote areas. Providing transportation support, such as subsidized or free transportation services, can ensure that pregnant women can reach healthcare facilities in a timely manner.
