Safety and tolerability of radiotherapy in combination with systemic targeted therapies for treatment of hepatocellular carcinoma: a narrative review.

BACKGROUND AND OBJECTIVE: Palliative radiotherapy (RT) and systemic immuno- or targeted therapy both play significant roles in the treatment of advanced hepatocellular carcinoma (HCC). Concurrent application of these therapies is increasing, however, no guidelines exist regarding the combination of systemic therapy with RT. This narrative review summarises the existing literature reporting toxicity observed after concurrent treatment with RT and immuno- or targeted therapeutic agents commonly used in HCC. METHODS: The PubMed database was searched for studies published between 2011 and 2023 reporting toxicity data on patients treated concurrently with RT and targeted agents used in HCC. Due to the paucity of relevant literature in HCC, the inclusion criteria were expanded to include non-HCC cohorts treated with targeted therapies commonly used in advanced HCC. KEY CONTENT AND FINDINGS: Sixty-seven articles were included in this review. Twenty-two articles reported combined RT with sorafenib, one with regorafenib, 22 with bevacizumab, three with lenvatinib and 19 with immune checkpoint inhibitors. Significant findings include a high rate severe hepatotoxicity with combination RT and sorafenib, ranging from 0-19% with liver stereotactic body radiotherapy (SBRT) and 3-18% with conventionally fractionated liver RT. Severe gastrointestinal (GI) toxicities including perforation and ulceration were seen with combination bevacizumab and RT, ranging from 0-27% in the acute setting and 0-23% in the late setting. The safety profile of combination immune checkpoint blockade agents and RT was similar to that seen in monotherapy. CONCLUSIONS: Existing data suggests that combination RT and targeted therapy given the risk of severe adverse events including hepatotoxicity and GI toxicity. There is an urgent need for future studies specifically examining the impact of combination therapy in HCC patients to guide clinical decision-making in the evolving landscape of immune- and targeted therapies.

Mental Health During Late Pregnancy and Postpartum in Mothers With and Without Type 1 Diabetes: The ENDIA Study.

OBJECTIVE: Pregnancy and type 1 diabetes are each associated with increased anxiety and depression, but the combined impact on well-being is unresolved. We compared the mental health of women with and without type 1 diabetes during pregnancy and postpartum and examined the relationship between mental health and glycemic control. RESEARCH DESIGN AND METHODS: Participants were women enrolled from 2016 to 2020 in the Environmental Determinants of Islet Autoimmunity (ENDIA) study, a pregnancy to birth prospective cohort following children with a first-degree relative with type 1 diabetes. Edinburgh Postnatal Depression Scale (EPDS) and Perceived Stress Scale (PSS) were completed during the third trimester (T3) (median [interquartile range] 34 [32, 36] weeks) and postpartum (14 [13, 16] weeks) by 737 women (800 pregnancies) with (n = 518) and without (n = 282) type 1 diabetes. RESULTS: EPDS and PSS scores did not differ between women with and without type 1 diabetes during T3 and postpartum. EPDS scores were marginally higher in T3: predicted mean (95% CI) 5.7 (5.4, 6.1) than postpartum: 5.3 (5.0, 5.6), independent of type 1 diabetes status (P = 0.01). HbA1c levels in type 1 diabetes were 6.3% [5.8, 6.9%] in T3 and did not correlate with EPDS or PSS scores. Reported use of psychotropic medications was similar in women with (n = 44 of 518 [8%]) and without type 1 diabetes (n = 17 of 282 [6%]), as was their amount of physical activity. CONCLUSIONS: Overall, mental health in late pregnancy and postpartum did not differ between women with and without type 1 diabetes, and mental health scores were not correlated with glycemic control.

New insights into carnitine-acylcarnitine translocase deficiency from 23 cases: Management challenges and potential therapeutic approaches.

Carnitine acyl-carnitine translocase deficiency (CACTD) is a rare autosomal recessive disorder of mitochondrial long-chain fatty-acid transport. Most patients present in the first 2 days of life, with hypoketotic hypoglycaemia, hyperammonaemia, cardiomyopathy or arrhythmia, hepatomegaly and elevated liver enzymes. Multi-centre international retrospective chart review of clinical presentation, biochemistry, treatment modalities including diet, subsequent complications, and mode of death of all patients. Twenty-three patients from nine tertiary metabolic units were identified. Seven attenuated patients of Pakistani heritage, six of these homozygous c.82G>T, had later onset manifestations and long-term survival without chronic hyperammonemia. Of the 16 classical cases, 15 had cardiac involvement at presentation comprising cardiac arrhythmias (9/15), cardiac arrest (7/15), and cardiac hypertrophy (9/15). Where recorded, ammonia levels were elevated in all but one severe case (13/14 measured) and 14/16 had hypoglycaemia. Nine classical patients survived longer-term-most with feeding difficulties and cognitive delay. Hyperammonaemia appears refractory to ammonia scavenger treatment and carglumic acid, but responds well to high glucose delivery during acute metabolic crises. High-energy intake seems necessary to prevent decompensation. Anaplerosis utilising therapeutic d,l-3-hydroxybutyrate, Triheptanoin and increased protein intake, appeared to improve chronic hyperammonemia and metabolic stability where trialled in individual cases. CACTD is a rare disorder of fatty acid oxidation with a preponderance to severe cardiac dysfunction. Long-term survival is possible in classical early-onset cases with long-chain fat restriction, judicious use of glucose infusions, and medium chain triglyceride supplementation. Adjunctive therapies supporting anaplerosis may improve longer-term outcomes.
