RESUMO

OBJECTIVE: To determine if mild-moderate hypertriglyceridemia is associated with increased development of chronic pancreatitis or pancreatitis-associated complications in children with acute recurrent or chronic pancreatitis. STUDY DESIGN: Longitudinal data from the INSPPIRE-2 (INternational Study group of Pediatric Pancreatitis: In search for a cuRE-2) cohort of children with acute recurrent or chronic pancreatitis (n=559) were analyzed. Subjects were divided into normal triglycerides (<150 mg/dL; 1.7 mmol/L), any hypertriglyceridemia (≥150 mg/dL; ≥1.7 mmol/L), mild-moderate hypertriglyceridemia (150-499 mg/dL; 1.7-5.6 mmol/L), moderate hypertriglyceridemia (500-999 mg/dL; 5.6-11.3 mmol/L), and severe hypertriglyceridemia groups (≥1,000 mg/dL; ≥11.3 mmol/L), based on highest serum triglyceride value. Laboratory, imaging, pancreatitis and hospital events, complications, and quality of life data were analyzed. RESULTS: In children with acute recurrent or chronic pancreatitis and hypertriglyceridemia, there was no increase in the number of pancreatitis attacks per person-years, nor an increase in chronic pancreatitis prevalence. However, hypertriglyceridemia severity was associated with increased pancreatic inflammation, pancreatic cysts, pain, hospital days, number of hospitalizations, intensive care, and missed school days. CONCLUSIONS: Mild-moderate hypertriglyceridemia in children with acute recurrent or chronic pancreatitis was not associated with increased pancreatitis frequency, nor increased development of chronic pancreatitis, but was associated with increased pancreatitis complications and disease burden. As a treatable condition, treatment of mild-moderate hypertriglyceridemia may be considered to reduce pancreatitis-associated complications and medical burden in children with acute recurrent or chronic pancreatitis.

RESUMO

INTRODUCTION: Among children who suffer from acute recurrent pancreatitis (ARP) or chronic pancreatitis (CP), acute pancreatitis (AP) episodes are painful, often require hospitalization, and contribute to disease complications and progression. Despite this recognition, there are currently no interventions to prevent AP episodes. In this retrospective cohort study, we assessed the impact of pancreatic enzyme therapy (PERT) use on clinical outcomes among children with pancreatic-sufficient ARP or CP. METHODS: Children with pancreatic-sufficient ARP or CP in the INSPPIRE-2 cohort were included. Clinical outcomes were compared for those receiving vs not receiving PERT, as well as frequency of AP before and after PERT. Logistic regression was used to study the association between development of AP episodes after starting PERT and response predictors. RESULTS: Among 356 pancreatic-sufficient participants, 270 (76%) had ARP, and 60 (17%) received PERT. Among those on PERT, 42% did not have a subsequent AP episode, during a mean 2.1 years of follow-up. Children with a SPINK1 mutation ( P = 0.005) and those with ARP (compared with CP, P = 0.008) were less likely to have an AP episode after starting PERT. After initiation of PERT, the mean AP annual incidence rate decreased from 3.14 down to 0.71 ( P < 0.001). DISCUSSION: In a retrospective analysis, use of PERT was associated with a reduction in the incidence rate of AP among children with pancreatic-sufficient ARP or CP. These results support the need for a clinical trial to evaluate the efficacy of PERT to improve clinical outcomes among children with ARP or CP.

RESUMO

BACKGROUND: Data on oral vancomycin for primary sclerosing cholangitis (PSC)-associated inflammatory bowel disease (IBD) are limited. AIMS: Using data from the Paediatric PSC Consortium, to examine the effect of vancomycin on IBD activity. METHODS: In this retrospective multi-centre cohort study, we matched vancomycin-treated and untreated patients (1:3) based on IBD duration at the time of primary outcome assessment. The primary outcome was Physician Global Assessment (PGA) of IBD clinical activity after 1 year (±6 months) of vancomycin. We used generalised estimating equations (GEE) to examine the association between vancomycin and PGA remission, adjusting for IBD type, severity and medication exposures. Secondary outcomes included serum labs and endoscopic remission (global rating of no activity) among those with available data and also analysed with GEE. RESULTS: 113 PSC-IBD patients received vancomycin (median age 12.7 years, 63% male). The matched cohort included 70 vancomycin-treated and 210 untreated patients. Vancomycin was associated with greater odds of IBD clinical remission (odds ratio [OR] 3.52, 95% CI 1.97-6.31; adjusted OR [aOR] 5.24, 95% CI 2.68-10.22). Benefit was maintained in sensitivity analyses restricted to non-transplanted patients and those with baseline moderate-severe PGA. Vancomycin was associated with increased odds of endoscopic remission (aOR 2.76, 95% CI 1.002-7.62; N = 101 with data), and with lower CRP (p = 0.03) and higher haemoglobin and albumin (both p < 0.01). CONCLUSION: Vancomycin was associated with greater odds of IBD clinical and endoscopic remission. Additional, preferably randomised, controlled studies are needed to characterise efficacy using objective markers of mucosal inflammation, and to examine safety and define optimal dosing.

RESUMO

OBJECTIVES: No study has explored whether availability of endoscopic retrograde cholangiopancreatography (ERCP) is adequate and equitable across US children's hospitals. We hypothesized that ERCP availability and utilization differs by geography and patient factors. METHODS: Healthcare encounter data from 2009 to 2019 on children with pancreatic and biliary diseases from the Pediatric Health Information System were analyzed. ERCP availability was defined as treatment at a hospital that performed pediatric ERCP during the year of service. RESULTS: From 2009 to 2019, 37,946 children (88,420 encounters) had a potential pancreatic or biliary indication for ERCP; 7066 ERCPs were performed. The commonest pancreatic diagnoses leading to ERCP were chronic (47.2%) and acute pancreatitis (43.2%); biliary diagnoses were calculus (68.3%) and obstruction (14.8%). No ERCP was available for 25.0% of pancreatic encounters and 8.1% of biliary encounters. In multivariable analysis, children with public insurance, rural residence, or of Black race were less likely to have pancreatic ERCP availability; those with rural residence or Asian race were less likely to have biliary ERCP availability. Black children or those with public insurance were less likely to undergo pancreatic ERCP where available. Among encounters for calculus or obstruction, those of Black race or admitted to hospitals in the West were less likely to undergo ERCP when available. CONCLUSIONS: One-in-four children with pancreatic disorders and one-in-12 with biliary disorders may have limited access to ERCP. We identified racial and geographic disparities in availability and utilization of ERCP. Further studies are needed to understand these differences to ensure equitable care.

RESUMO

INTRODUCTION: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease among US children. Studies have associated food insecurity with MASLD in adults, but there are few studies of pediatric MASLD, particularly in high-risk populations. We assessed the impact of household food insecurity at 4 years of age on MASLD in Latinx children. METHODS: Using a prospective cohort design, Latina mothers were recruited during pregnancy and followed with their children until early to mid-childhood. Our primary exposure was household food insecurity at 4 years of age measured using the validated US Household Food Security Food Module. Our primary outcome, MASLD, was defined as alanine transaminase (ALT) ≥95th% for age/gender plus body mass index (BMI) ≥85% at time of ALT measurement (assessed between ages 5-12). We used multivariable logistic regression models to test for independent associations between household food insecurity and pediatric MASLD. RESULTS: Among 136 children, 28.7% reported household food insecurity at 4 years of age and 27.2% had MASLD in early to middle childhood. Approximately 49% of children with MASLD and 21% of children without MASLD were food insecure (p < 0.01). Exposure to household food insecurity at age 4 was independently associated with a 3.7-fold higher odds of MASLD later in childhood (95% CI: 1.5-9.0, p < 0.01). CONCLUSIONS: Exposure to household food insecurity at 4 years of age was associated with increased risk for MASLD later in childhood. Further studies are needed to explore mechanism(s) and impact of reducing food insecurity on risk for MASLD.

RESUMO

BACKGROUND: Adult patients with biliary acute pancreatitis (BAP) or choledocholithiasis who do not undergo cholecystectomy on index admission have worse outcomes. Given the paucity of data on the impact of cholecystectomy during index hospitalization in children, we examined readmission rates among pediatric patients with BAP or choledocholithiasis who underwent index cholecystectomy versus those who did not. METHODS: Retrospective study of children (< 18 years old) admitted with BAP, without infection or necrosis (ICD-10 K85.10), or choledocholithiasis (K80.3x-K80.7x) using the 2018 National Readmission Database (NRD). Exclusion criteria were necrotizing pancreatitis with or without infected necrosis and death during index admission. Multivariable logistic regression was performed to identify factors associated with 30-day readmission. RESULTS: In 2018, 1122 children were admitted for index BAP (n = 377, 33.6%) or choledocholithiasis (n = 745, 66.4%). Mean age at admission was 13 (SD 4.2) years; most patients were female (n = 792, 70.6%). Index cholecystectomy was performed in 663 (59.1%) of cases. Thirty-day readmission rate was 10.9% in patients who underwent cholecystectomy during that index admission and 48.8% in those who did not (p < 0.001). In multivariable analysis, patients who underwent index cholecystectomy had lower odds of 30-day readmission than those who did not (OR 0.16, 95% CI 0.11-0.24, p < 0.001). CONCLUSIONS: Index cholecystectomy was performed in only 59% of pediatric patients admitted with BAP or choledocholithiasis but was associated with 84% decreased odds of readmission within 30 days. Current guidelines should be updated to reflect these findings, and future studies should evaluate barriers to index cholecystectomy.

RESUMO

OBJECTIVES: The Starzl Network for Excellence in Pediatric Transplantation identified optimizing immunosuppression (IS) as a priority practice improvement area for patients, families, and providers. We aimed to evaluate associations between clinical characteristics, early IS, and outcomes. METHODS: We analyzed pediatric liver transplant (LT) data from 2013 to 2018 in the United Network for Organ Sharing (UNOS) and the Society of Pediatric Liver Transplantation (SPLIT) registries. RESULTS: We included 2542 LT recipients in UNOS and 1590 in SPLIT. IS choice varied between centers with steroid induction and mycophenolate mofetil (MMF) use each ranging from 0% to 100% across centers. Clinical characteristics associated with early IS choice were inconsistent between the two data sets. T-cell depleting antibody use was associated with improved 1-year graft (hazard ratio [HR] 0.50, 95% confidence interval [CI] 0.34-0.76) and patient (HR 0.40, 95% CI 0.20-0.79) survival in UNOS but decreased 1-year patient survival (HR 4.12, 95% CI 1.31-12.93) and increased acute rejection (HR 1.58, 95% CI 1.07-2.34) in SPLIT. Non-T-cell depleting antibody use was not associated with differential risk of survival nor rejection. MMF use was associated with improved 1-year graft survival (HR 0.73, 95% CI 0.54-0.99) in UNOS only. CONCLUSIONS: Variation exists in center choice of early IS regimen. UNOS and SPLIT data provide conflicting associations between IS and outcomes in multivariable analysis. These results highlight the need for future multicenter collaborative work to identify evidence-based IS best practices.

RESUMO

Pediatric liver transplant (LT) recipients navigate a lifelong journey that includes constant monitoring and challenges. Research priorities and questions in LT have traditionally been provider-driven. This project was a novel partnership between a learning health system dedicated to pediatric LT (Starzl Network for Excellence in Pediatric Transplantation) and a parent-led advocacy group (Transplant Families) that aimed to prepare families and providers for collaborative patient-centered outcomes research (PCOR). We developed 5 virtual modules to (1) teach participants about PCOR, and (2) elicit ideas for PCOR priorities and processes in pediatric LT. Parents and providers participated via self-guided online modules or focus groups. Participants included 240 patient partners and 133 pediatric LT providers from 16 centers over 2 years. We held 20 focus groups, including 5 to amplify underrepresented voices: young adults, Spanish speakers, and African Americans. Feedback was summarized to create a PCOR Roadmap, a guide for future PCOR in the Starzl Network, which was disseminated back to participants online and via webinars. Feedback from a diverse group of stakeholders allowed us to develop PCOR priorities and processes for the pediatric LT community. Our engagement strategies could be adapted by other transplant communities to facilitate patient and provider research partnerships.

RESUMO

BACKGROUND: Adolescent solid organ transplant recipients (aSOTRs) who received three doses of the COVID-19 mRNA vaccine experience high seroconversion rates and antibody persistence for up to 3 months. Long-term antibody durability beyond this timeframe following three doses of the SARS-CoV-2 mRNA vaccine remains unknown. We describe antibody responses 6 months following the third vaccine dose (D3) of the BNT162b2 mRNA vaccination among aSOTRs. METHODS: Participants in a multi-center, observational cohort who received the third dose of the vaccine were analyzed for antibodies to the SARS-CoV-2 spike protein receptor-binding domain (Roche Elecsys anti-SARS-CoV-2-S positive: ≥0.8, maximum: >2500 U/mL). Samples were collected at 1-, 3-, and 6-months post-D3. Participants were surveyed at each timepoint and at 12-months post-D3. RESULTS: All 34 participants had positive anti-RBD antibody titers 6 months post-D3. Variations in titers occurred between 3 and 6 months post-D3, with 8/28 (29%) having decreased antibody levels at 6 months compared to 3 months and 2/28 (7%) reporting increased titers at 6 months. The remaining 18/28 (64%) had unchanged antibody titers compared to 3-month post-D3 levels. A total of 4/34 (12%) reported breakthrough infection within 6 months and 3/32 (9%) reported infection after 6-12 months following the third dose of the SARS-CoV-2 mRNA vaccine. CONCLUSIONS: The results suggest that antibody durability persists up to 6 months following three doses of the SARS-CoV-2 mRNA in aSOTRs. Demography and transplant characteristics did not differ for those who experienced antibody weaning. Breakthrough infections did occur, reflecting immune-evasive nature of novel variants such as Omicron.

RESUMO

Children from minoritized/socioeconomically deprived backgrounds suffer disproportionately high rates of uninsurance and graft failure/death after liver transplant. Medicaid expansion was developed to expand access to public insurance. Our objective was to characterize the impact of Medicaid expansion policies on long-term graft/patient survival after pediatric liver transplantation. All pediatric patients (<19 years) who received a liver transplant between January 1, 2005, and December 31, 2020 in the US were identified in the Scientific Registry of Transplant Recipients (N = 8489). Medicaid expansion was modeled as a time-varying exposure based on transplant and expansion dates. We used Cox proportional hazards models to evaluate the impact of Medicaid expansion on a composite outcome of graft failure/death over 10 years. As a sensitivity analysis, we conducted an intention-to-treat analysis from time of waitlisting to death (N = 1 1901). In multivariable analysis, Medicaid expansion was associated with a 30% decreased hazard of graft failure/death (hazard ratio, 0.70; 95% confidence interval, 0.62, 0.79; P < .001) after adjusting for Black race, public insurance, neighborhood deprivation, and living in a primary care shortage area. In intention-to-treat analyses, Medicaid expansion was associated with a 72% decreased hazard of patient death (hazard ratio, 0.28; 95% confidence interval, 0.23-0.35; P < .001). Policies that enable broader health insurance access may help improve outcomes and reduce disparities for children undergoing liver transplantation.

RESUMO

The exception point system for liver allocation in the United States allows for additional waitlist priority for candidates where the Model for End-Stage Liver Disease or Pediatric End-stage Liver Disease does not effectively represent their urgency or need for a transplant. In May 2019, the review process for liver exception cases transitioned from 11 Regional Review Boards (RRBs) to 1 National Liver Review Board (NLRB), intended to increase consistency nationwide, improve efficiency, and balance transplant access for candidates with and without exception scores. This report provides a review of liver exception request and review practices, waitlist outcomes, and transplant activity in the first 2 years after implementation of the NLRB and acuity circle-based distribution in the United States. We compared initial and extension exception request forms submitted from May 13, 2017 to May 13, 2019 (prepolicy or RRB era) to the period from February 4, 2020 to February 3, 2022 (postpolicy or NLRB era). During this time, the NLRB reviewed 10,083 initial exception requests and 12,686 extension requests. Notable postpolicy highlights include (1) an increase in the proportion of initial and extension requests that were automatically approved instead of manually reviewed; (2) a decrease in the overall approval rates of initial exception requests (87.8% for adult HCC, 64.3% for adult other diagnoses, and 71.5% for pediatric); and (3) reduction in the time from exception request submission to adjudication to a median of 3.73 days. The proportions of waitlist registration and deceased donor liver transplants for patients with exception scores decreased, and waitlist outcomes between patients with and without exception scores are now comparable. Implementation of the NLRB improved efficiency, reduced case workloads, and standardized criteria for exception cases, with similar waitlist outcomes between patients with and without exception scores and improved equity in terms of access to liver transplants.

RESUMO

SARS-CoV-2 infection during the Omicron period was frequent amongst a cohort of vaccinated pediatric solid organ transplant recipients (pSOTRs) despite robust anti-receptor-binding domain (anti-RBD) antibody response, suggesting poor neutralizing capacity against Omicron subvariants. Breakthrough infections among pSOTRs were overall limited in severity.

RESUMO

BACKGROUND/OBJECTIVES: Bone health of children with acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) is not well studied. METHODS: This retrospective study was performed at three sites and included data from INSPPIRE-2. RESULTS: Of the 87 children in the study: 46 had ARP (53%), 41 had CP (47%). Mean age was 13.6 ± 3.9 years at last DXA scan. The prevalence of low height-for-age (Z-score < -2) (13%, 10/78) and low bone mineral density (BMD) adjusted for height (Z-score < -2) (6.4%, 5/78) were higher than a healthy reference sample (2.5%, p < 0.0001 and p = 0.03, respectively). CONCLUSION: Children with ARP or CP have lower height and BMD than healthy peers. Attention to deficits in growth and bone mineral accrual in children with pancreatic disease is warranted.

RESUMO

INTRODUCTION: Although clinicians repeatedly measure ALT to assess allograft health in children with liver transplants, they generally make decisions based on single values or qualitative trends without quantitative aggregation or synthesis. We therefore aimed to derive and test a holistic ALT metric for the 5th post-transplant year (Yr 4-5) that may better guide clinical decision-making and/or population comparisons. METHODS: We derived the "adjusted mean Yr 4-5 ALT" for children transplanted in 2005-2016 by averaging the median ALT from each month. Patients in quartiles (Q1-4) defined by the adjusted mean Yr 4-5 ALT were compared by clinical variables, Yr 5-8 outcomes, and tacrolimus standard deviation (MLVI). RESULTS: For 97 children [49 male; 77 deceased donors; median (IQR) age at LT 2.5 (0.8-11.7) years], the 25th, 50th, and 75th percentile thresholds for adjusted mean Yr 4-5 ALT were 19, 28, and 47 U/L, respectively. Age, donor type, LT indication, rejection history, and mean tacrolimus levels did not differ between quartiles (Q). Children in Q4 had more Yr 4-5 acute rejection episodes (p < .01), higher Yr 4-5 MLVI (p < .01), and more Yr 5-8 for-cause liver biopsies (p < .01) than those in Q1 + Q2. Children in Q3 also had higher Yr 4-5 MLVI than Q1 + Q2 (p = .047). Rates of chronic rejection and therapeutic liver-related procedures were higher in Q4 but the difference did not reach significance. CONCLUSION: An integrated ALT metric calculated utilizing all available ALT values correlates with MLVI and future for-cause biopsies. Further study of this novel ALT metric as a predictor of clinical outcomes and descriptor of populations is warranted.

RESUMO

OBJECTIVES: Drug-associated acute pancreatitis (DAP) studies typically focus on single acute pancreatitis (AP) cases. We aimed to analyze the (1) characteristics, (2) co-risk factors, and (3) reliability of the Naranjo scoring system for DAP using INSPPIRE-2 (the INternational Study group of Pediatric Pancreatitis: In search for a cuRE-2) cohort study of acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) in children. METHODS: Data were obtained from ARP group with ≥1 episode of DAP and CP group with medication exposure ± DAP. Physicians could report multiple risk factors. Pancreatitis associated with Medication (Med) (ARP+CP) was compared to Non-Medication cases, and ARP-Med vs CP-Med groups. Naranjo score was calculated for each DAP episode. RESULTS: Of 726 children, 392 had ARP and 334 had CP; 51 children (39 ARP and 12 CP) had ≥1 AP associated with a medication; 61% had ≥1 AP without concurrent medication exposure. The Med group had other risk factors present (where tested): 10 of 35 (28.6%) genetic, 1 of 48 (2.1%) autoimmune pancreatitis, 13 of 51 (25.5%) immune-mediated conditions, 11 of 50 (22.0%) obstructive/anatomic, and 28 of 51 (54.9%) systemic risk factors. In Med group, 24 of 51 (47%) had involvement of >1 medication, simultaneously or over different AP episodes. There were 20 ARP and 4 CP cases in "probable" category and 19 ARP and 7 CP in "possible" category by Naranjo scores. CONCLUSIONS: Medications were involved in 51 of 726 (7%) of ARP or CP patients in INSPPIRE-2 cohort; other pancreatitis risk factors were present in most, suggesting a potential additive role of different risks. The Naranjo scoring system failed to identify any cases as "definitive," raising questions about its reliability for DAP.

RESUMO

Autoimmune hepatitis (AIH) is a severe autoimmune disease, characterized by the presence of autoantibodies. However, the role of autoantibodies in the pathophysiology of AIH remains uncertain. Here, we employed Phage Immunoprecipitation-Sequencing (PhIP-Seq) to identify novel autoantibodies in AIH. Using these results, a logistic regression classifier was able to predict which patients had AIH, indicating the presence of a distinct humoral immune signature. To further investigate the autoantibodies most specific to AIH, significant peptides were identified relative to a broad array of controls (298 patients with non-alcoholic fatty liver disease (NAFLD), primary biliary cholangitis (PBC), or healthy controls). Top ranked autoreactive targets included SLA, the target of a well-recognized autoantibody in AIH, and disco interacting protein 2 homolog A (DIP2A). The autoreactive fragment of DIP2A shares a 9-amino acid stretch nearly identical to the U27 protein of HHV-6B, a virus found in the liver. In addition, antibodies against peptides derived from the leucine rich repeat N-terminal (LRRNT) domain of the relaxin family peptide receptor 1 (RXFP1) were highly enriched and specific to AIH. The enriched peptides map to a motif adjacent to the receptor binding domain, which is required for RXFP1 signaling. RXFP1 is a G protein-coupled receptor that binds relaxin-2, an anti-fibrogenic molecule shown to reduce the myofibroblastic phenotype of hepatic stellate cells. Eight of nine patients with antibodies to RXFP1 had evidence of advanced fibrosis (F3 or greater). Furthermore, serum from AIH patients positive for anti-RFXP1 antibody was able to significantly inhibit relaxin-2 signaling in the human monocytic cell line, THP1. Depletion of IgG from anti-RXFP1 positive serum abrogated this effect. These data provide supporting evidence that HHV6 plays a role in the development of AIH and point to a potential pathogenic role for anti-RXFP1 IgG in some patients. Identification of anti-RXFP1 in patient serum may enable risk stratification of AIH patients for fibrosis progression and lead to the development of novel strategies for disease intervention.

RESUMO

OBJECTIVE: To inform approaches to pediatric medical traumatic stress (PMTS) by exploring providers' (1) perception of the impact of PMTS on the medical care of patients with pediatric-onset chronic illnesses, (2) self-reported competencies and practices of PMTS prevention, treatment, and counseling, and (3) perception of the barriers influencing the adoption of these practices. STUDY DESIGN: A convenience sample of multidisciplinary healthcare providers was recruited through a multimodal recruitment strategy to participate in an electronic survey adapted from the Trauma-Informed Care Provider Survey. RESULTS: Among participants (n = 304), 99% agreed that PMTS impacts patient health. Participants report altering medical care plans due to PMTS, including deferring or stopping treatments (n = 98 [32%]) and changing medication regimens (n = 88 [29%]). Sixty-eight percent (n = 208) report negative impact of PMTS on patient implementation of medical care plans, including medication nonadherence (n = 153 [50%]) and missed appointments (n = 119 [39%]). Although participants agreed it is their job to decrease patient stress (n = 292 [96%]) and perform PMTS assessments (n = 268 [88%]), few practiced PMTS-focused trauma informed care. Systems-level barriers to practice included insufficient training, absent clinical workflows, and lack of access to mental health experts. CONCLUSIONS: Our findings have helped inform a conceptual framework for understanding the relationship between PMTS and health outcomes. Systems-level opportunities to optimize PMTS-focused trauma-informed care include (1) dissemination of provider training, (2) integrated workflows for PMTS mitigation, and (3) enhanced accessibility to mental health providers. Further work is required to determine if these interventions can improve health outcomes in patients with pediatric-onset chronic illnesses.

RESUMO

OBJECTIVES: Polycystic ovary syndrome (PCOS) increases non-alcoholic fatty liver disease (NAFLD) risk and severity in adults, but data in adolescents with diverse backgrounds are limited. We evaluated NAFLD prevalence and characterized NAFLD risk factors in overweight/obese adolescents by PCOS status. METHODS: Retrospective study of overweight (n=52)/obese (n=271) female adolescents (12-18 years old), evaluated clinically 2012-2020, was conducted comparing PCOS patients to age-matched non-PCOS controls. NAFLD was defined as ALT≥44U/L x2 and/or ≥80U/L x1, hepatic steatosis on imaging, or NAFLD on biopsy, in absence of other liver disease. Metabolic comorbidities were captured. Log-binomial regression models estimated prevalence risk ratios (PR). RESULTS: NAFLD prevalence was 19.1 % in adolescents with PCOS (n=161), similar to those without (n=162) (16.8 %, p=0.6). Adolescents with PCOS were more likely to have insulin resistance, hypercholesterolemia, and higher triglycerides (p<0.05). Those with PCOS and concomitant type 2 diabetes (T2DM) did have increased NAFLD risk (PR 2.5, p=0.04), but those with PCOS without T2DM did not (PR 0.9, p=0.8). Adolescents with PCOS and NAFLD, compared to those with PCOS without NAFLD, had a higher prevalence of metabolic comorbidities including hypercholesterolemia (77 vs. 48 %), T2DM (29 vs. 8 %), and hypertriglyceridemia (65 vs. 37 %) (p<0.01). CONCLUSIONS: Almost 1 in 5 overweight/obese female adolescents had NAFLD, but PCOS did not increase NAFLD risk in this diverse cohort. Among young women with PCOS, concomitant T2DM did increase the risk for NAFLD. Closer monitoring of obesity comorbidities in adolescents with PCOS is essential for optimizing health and merits updating current guidelines.
