入选标准

  • Age 12 months to 18 years (infantile form is out of scope for the analytical component);
  • Patients not previously evaluated for LAL-D (test-naïve);
  • Presence of at least one (1) of the following major criteria:
  • Unexplained hepatomegaly and/or splenomegaly persisting ≥3 months;
  • Persistent hypertransaminasemia: ALT or AST ≥ 1.5× upper limit of normal (ULN) after exclusion of common metabolic/infectious causes;
  • Atherogenic dyslipidemia: elevated total cholesterol (TC), elevated LDL-C and/or reduced HDL-C (LDL-C >95th percentile for age and sex or HDL-C <5th percentile); triglycerides not markedly elevated.
  • Presence of at least two (2) of the following minor criteria:
  • Chronic diarrhea or intermittent unstable bowel movements;
  • Abdominal pain and/or bloating;
  • Loss of appetite;
  • Nausea, vomiting;
  • Belching, heartburn;
  • Weight loss, growth deceleration (height/weight lag behind peers);
  • Weakness, easy fatigability;
  • Recurrent aphthous stomatitis (oral mucosal ulcers);
  • Splenomegaly (if not counted as a major criterion);
  • Anemia and/or thrombocytopenia;
  • Evidence of steatosis/fibrosis by ultrasound/elastography/ liver examination by MRI;
  • Suboptimal response to lipid-lowering therapy: after ≥3 months of optimized therapy (maximally tolerated statin ± ezetimibe with documented adherence), LDL-C reduction <50% from baseline OR on-treatment LDL-C remains above guideline targets (e.g., ≥3.4 mmol/L without very high risk or ≥2.6 mmol/L in very-high-risk settings), despite therapy [12].
  • Family history of FH-like dyslipidemia without typical FH genetic markers (if available).
  • Provision of signed and dated written informed consent by parent(s)/legal guardian(s) (and the child, where applicable).

排除标准

  • Confirmed alternative etiology fully explaining liver disease/dyslipidemia (e.g., hepatitis A/B/C, autoimmune hepatitis by diagnostic criteria) without grounds to suspect LAL-D;
  • Wolman disease;
  • Long-term use of systemic corticosteroids which is defined as oral or parenteral continuous administration during ≥14 days in the last 6 months prior to the inclusion.

结局指标

主要结局

To estimate the proportion of patients with genetically confirmed LAL-D (defined by decreased LAL activity plus presence of biallelic pathogenic LIPA variants) among 12-month-to-18-year-old patients identified by predefined red flags.

时间窗: Day 60 (Visit 2)

To achieve the primary objectives of the study the following baseline clinical and demographic characteristics of patients will be collected or evaluated. Proportion (%), with 95% confidence interval, of patients with genetically confirmed LAL-D among screened participants (confirmation by LIPA sequencing following detection of decreased LAL activity in DBS)
