Association of LDL-cholesterol <1.8 mmol/L and statin use with the recurrence of intracerebral hemorrhage.

BACKGROUND: Recent intensive low-density lipoprotein cholesterol (LDL-C) lowering trials, including FOURIER, ODYSSEY OUTCOMES, and Treat Stroke to Target (TST) trials, have mostly refuted the concern surrounding statin use, LDL-C lowering, and intracerebral hemorrhage (ICH) risk. However, the results from these trials may not be fully applied to ICH survivors, as the populations studied were mainly patients without prior ICH, in whom the inherent ICH risk is more than 10 times lower than that of ICH survivors. Although available literature on statin use after ICH has demonstrated no excess risk of recurrent ICH, other potential factors that may modify ICH risk, especially hypertension control and ICH etiology, have not generally been considered. Notably, data on LDL-C levels following ICH are lacking. AIMS: We aim to investigate the association between LDL-C levels and statin use with ICH risk among ICH survivors, and to determine whether the risk differed with patients' characteristics, especially ICH etiology. METHODS: Follow-up data of consecutive spontaneous ICH survivors enrolled in the University of Hong Kong prospective stroke registry from 2011 to 2019 were retrospectively analyzed. ICH etiology was classified as cerebral amyloid angiopathy (CAA) using the modified Boston criteria or hypertensive arteriopathy, while the mean follow-up LDL-C value was categorized as <1.8 or ⩾1.8 mmol/L. The primary endpoint was recurrent ICH. The association of LDL-C level and statin use with recurrent ICH was determined using multivariable Cox regression. Pre-specified subgroup analyses were performed, including based on ICH etiology and statin prescription. Follow-up blood pressure was included in all the regression models. RESULTS: In 502 ICH survivors (mean age = 64.2 ± 13.5 years, mean follow-up LDL-C = 2.2 ± 0.6 mmol/L, 28% with LDL-C <1.8 mmol/L), 44 had ICH recurrence during a mean follow-up of 5.9 ± 2.8 years. Statin use after ICH was not associated with recurrent ICH (adjusted hazard ratio (AHR) = 1.07, 95% confidence interval (CI) = 0.57-2.00). The risk of ICH recurrence was increased for follow-up LDL-C <1.8 mmol/L (AHR = 1.99, 95% CI = 1.06-3.73). This association was predominantly observed in ICH attributable to CAA (AHR = 2.52, 95% CI = 1.06-5.99) and non-statin users (AHR = 2.91, 95% CI = 1.08-7.86). CONCLUSION: The association between post-ICH LDL-C <1.8 mmol/L and recurrent ICH was predominantly observed in CAA patients and those with intrinsically low LDL-C (non-statin users). While statins can be safely prescribed in ICH survivors, LDL-C targets should be individualized and caution must be exercised in CAA patients.

Non-alcoholic fatty liver disease and type 2 diabetes: An update.

The global prevalence of non-alcoholic fatty liver disease (NAFLD) is rising, along with the epidemic of diabesity. NAFLD is present in >70% of individuals with type 2 diabetes. Although the mutually detrimental relationship between NAFLD and type 2 diabetes has been well established, a multitude of recent studies have further shown that type 2 diabetes is closely linked to the development of cirrhosis, hepatocellular carcinoma, liver-related morbidity and mortality. In contrast, NAFLD also negatively impacts type 2 diabetes both in terms of its incidence and related adverse clinical outcomes, including cardiovascular and chronic kidney diseases. In response to these global health threats, clinical care pathways for NAFLD and guidelines for metabolic dysfunction-associated fatty liver disease have been developed. Several antidiabetic agents have been evaluated for their potential hepatic benefits with promising results. Furthermore, type 2 diabetes patients are increasingly represented in clinical trials of novel therapeutics for NAFLD. However, despite the wealth of knowledge in NAFLD and type 2 diabetes, lack of awareness of the disease and the potential weight of this problem remains a major challenge, especially among clinicians who are outside the field of hepatology and gastroenterology. This review therefore aimed to provide all diabetes care providers with a summary of the latest evidence that supports NAFLD as an emerging diabetic complication of increasing importance, and to present the current recommendations, focusing on the assessment and therapeutic strategies, on the management of NAFLD among type 2 diabetes patients.

Glycogenic hepatopathy as an unusual etiology of deranged liver function in a patient with type 1 diabetes: A case report.

RATIONALE: Deranged liver function is a common finding among patients with diabetes mellitus. We report a case of liver biopsy-proven glycogenic hepatopathy (GH) in a patient with long-standing poorly controlled type 1 diabetes (DM1), presented with recurrent transaminitis. PATIENT CONCERNS: A 28-year-old Chinese woman was noted to have deranged liver function with transaminases elevated to more than 15 times the upper limit of normal. DIAGNOSIS: She had underlying long-standing poorly controlled DM1. Blood tests including hepatitis serology and autoimmune panel were negative. Liver biopsy confirmed the diagnosis of GH, showing an increase in glycogen deposition with intact liver parenchymal architecture, and no inflammation or significant fibrosis. INTERVENTIONS: Her glycemic control was optimized. OUTCOMES: Her transaminase levels normalized upon subsequent follow-up with improved glycemic control. LESSONS: GH is suspected when transaminase flare occurs in patients with poorly controlled DM1, usually with exaggerated hemoglobin A1c levels, especially after drug-induced, viral, autoimmune and metabolic liver diseases are excluded. The gold standard of diagnosis is liver biopsy. When diagnosis of GH is ascertained, the mainstay of treatment is to optimize glycemic control. Typically, the transaminases may become normal within days to months after improvement of glycemic control. Compared to non-alcoholic fatty liver disease, GH is associated with favorable prognosis and runs a benign course, making this differentiation clinically important.
