Effects of Maternal SARS-CoV-2 Infection on Neonatal Discharge Planning and Care: Exacerbation of Racial and Ethnic Healthcare Disparities.

OBJECTIVES: To determine if SARS-CoV-2 disproportionately impacted infants born to racial and ethnic minorities and if virus exposure led to decreased access to care. METHODS: This study was an observational case-control study, between March 2020 and March 2022 in Portland, Maine. Forty-seven cases and 47 controls were enrolled. Cases were infants born to mothers diagnosed with SARS-CoV-2 at delivery, and controls were infants matched by date of birth, born to SARS-CoV-2 negative women. Demographic data, maternal clinical data, infant outcomes, and infant discharge plans were compared using Chi squared or Fisher Exact tests. Logistic regression was used to examine the impact of race on neonatal SARS-CoV-2 exposure. RESULTS: Infants exposed to SARS-CoV-2 were more likely Black or Hispanic than White and Non-Hispanic early in the pandemic, with reversal during the second year. SARS-CoV-2-exposed infants experienced delays in routine newborn outpatient care, although delay improved over the pandemic. CONCLUSION: Infants exposed to SARS-CoV-2 were initially more likely to be infants of color. During this time, infants exposed to SARS-CoV-2 were also experiencing significant delays in newborn care.

Everything old is new again: a case series of pediatric cutaneous leishmaniasis in Portland, Maine.

Leishmaniasis has varying clinical manifestations and treatment regimens, dependent on species and host. Old world leishmaniasis, found primarily in Africa and Asia, may be associated with visceral disease, while new world disease, primarily in Latin America, may be associated with mucocutaneous disease. We present a case series of pediatric African patients with New World cutaneous leishmaniasis. Data extraction was performed via chart review, of children with cutaneous leishmaniasis presenting to the pediatric infectious diseases clinic in Portland, ME. Biopsy specimens were sent to the federal center for disease control (CDC) for identification via polymerase chain reaction (PCR) and culture. Five cases of cutaneous leishmaniasis were diagnosed in pediatric patients (ages 1-17 years) in Maine during the study period. Leishmaniasis was not initially suspected; thus, time to diagnosis was 1-4 months, Two patients were diagnosed with Leishmania panamensis, one with Leishmania brasiliensis, one with Leishmania sp. and one with mixed infection (L. panamensis and Leishmania mexicana). One patient was managed with surgical excision only, one was observed off therapy, and three were treated with ketoconazole. This case series highlights the importance of a high index of suspicion in migrant patients. Detailed travel history and epidemiologic knowledge is essential to diagnosis, as patients may present with forms of illness not congruent with their country of origin.

Low Vitamin-D Levels Combined with PKP3-SIGIRR-TMEM16J Host Variants Is Associated with Tuberculosis and Death in HIV-Infected and -Exposed Infants.

BACKGROUND: This study examined the associations of 25-hydroxyvitamin D and specific host genetic variants that affect vitamin D levels or its effects on immune function, with the risk of TB or mortality in children. METHODS: A case-cohort sample of 466 South African infants enrolled in P1041 trial (NCT00080119) underwent 25-hydroxyvitamin D testing by chemiluminescent immunoassay. Single nucleotide polymorphisms (SNPs) that alter the effect of vitamin D [e.g. vitamin D receptor (VDR)], vitamin D levels [e.g. vitamin D binding protein (VDBP)], or toll like receptor (TLR) expression (SIGIRR including adjacent genes PKP3 and TMEM16J) were identified by real-time PCR. Outcomes were time to TB, and to the composite of TB or death by 192 weeks of follow-up. Effect modification between vitamin D status and SNPs for outcomes was assessed. FINDINGS: Median age at 25-hydroxyvitamin D determination was 8 months; 11% were breastfed, 51% were HIV-infected and 26% had low 25-hydroxyvitamin D (<32ng/mL). By 192 weeks, 138 incident TB cases (43 definite/probable, and 95 possible) and 26 deaths occurred. Adjusting for HIV status and potential confounders, low 25-hydroxyvitamin D was associated with any TB (adjusted hazard ratio [aHR] 1.76, 95% CI 1.01-3.05; p = 0.046) and any TB or death (aHR 1.76, 95% CI 1.03-3.00; p = 0.038). Children with low 25-hydroxyvitamin D and TMEM 16J rs7111432-AA or PKP3 rs10902158-GG were at increased risk for probable/definite TB or death (aHR 8.12 and 4.83, p<0.05) and any TB or death (aHR 4.78 and 3.26, p<0.005) respectively; SNPs in VDBP, VDR, and vitamin D precursor or hydroxylation genes were not. There was significant interaction between low 25-hydroxyvitamin D and, TMEM 16J rs7111432-AA (p = 0.04) and PKP3 rs10902158-GG (p = 0.02) SNPs. CONCLUSIONS: Two novel SNPs, thought to be associated with innate immunity, in combination with low vitamin D levels were identified as increasing a young child's risk of developing TB disease or death. Identifying high-risk children and providing targeted interventions such as vitamin D supplementation may be beneficial. TRIAL REGISTRATION: ClinicalTrials.gov NCT00080119.

Pediatric tuberculosis in young children in India: a prospective study.

BACKGROUND: India has one of the highest tuberculosis (TB) burdens globally. However, few studies have focused on TB in young children, a vulnerable population, where lack of early diagnosis results in poor outcomes. METHODS: Young children (≤ 5 years) with suspected TB were prospectively enrolled at a tertiary hospital in Pune, India. Detailed clinical evaluation, HIV testing, mycobacterial cultures, and drug susceptibility testing were performed. RESULTS: 223 children with suspected TB were enrolled. The median age was 31 months, 46% were female, 86% had received BCG, 57% were malnourished, and 10% were HIV positive. 12% had TB disease (definite or probable), 35% did not have TB, while TB could not be ruled out in 53%. Extrapulmonary disease was noted in 46%, which was predominantly meningeal. Tuberculin skin test (TST) was positive in 20% of children with TB. Four of 7 (57%) children with culture-confirmed TB harbored drug-resistant (DR) strains of whom 2 (50%) were multi-DR (MDR). In adjusted analyses, HIV infection, positive TST, and exposure to household smoke were found to be significantly associated with children with TB (P ≤ 0.04). Mortality (at 1 year) was 3 of 26 (12%) and 1 of 79 (1%), respectively, in children with TB and those without TB (P < 0.05). CONCLUSIONS: Diagnosis of TB is challenging in young children, with high rates of extra-pulmonary and meningeal disease. While the data on DR-TB are limited by the small sample size, they are however concerning, and additional studies are needed to more accurately define the prevalence of DR strains in this vulnerable population.
