Rationale: Although essential thrombocythemia (ET) and immune thrombocytopenia (ITP) have different etiologies, 3 previous reports have described ET development in ITP patients, all of whom were positive for the JAK2 V617F mutation. Here, we report the first published case of ITP following ET in the absence of other platelet disorders.
Patient Concerns: A 70-year-old woman with a five-year history of ET with JAK2 V617F mutation treated with hydroxycarbamide for five months presented with petechiae on her limbs.
Diagnosis: Her platelet count was 3 × 10/L, with the immature platelet fraction being 29%. White blood cell count and hemoglobin level were normal. Bone marrow examination showed increased number of megakaryocytes, but no morphologic dysplasia in any lineage. G-band analysis revealed no abnormalities. Platelet transfusion and cessation of hydroxycarbamide did not affect the platelet count. Thrombocytopenia was unlikely to have been induced by drugs, heparin, systemic lupus erythematosus, or human immunodeficiency virus. Hence, a diagnosis of ITP was made.
Interventions: The patient received oral prednisolone combined with intravenous immunoglobulin.
Outcomes: Her platelet count rose to 310 × 10/L and remained stable, while her steroid dose was reduced. Further blood tests revealed the presence of antibodies against Helicobacter pylori, and appropriate treatment was administered. Resumption of hydroxycarbamide did not induce thrombocytopenia.
Lessons: Although ET and ITP have different etiologies, chronic inflammation and immune deregulation underlie both and may play an important role in the progression from one to the other. Further research is warranted to understand the relationship between ET and ITP.

Aim: Chronic hepatitis C virus infections can lead to liver fibrosis. Appropriate treatment of chronic hepatitis C may result in significant fibrosis reversal. The best method to assess liver fibrosis is an invasive hepatic biopsy.

Objective: To establish a prediction nomogram for early prediction of neonatal acute respiratory distress syndrome (NARDS).
Methods: This is a retrospective cross-sectional study conducted between January 2021 and December 2023. Clinical characteristics and laboratory results of cases with neonatal pneumonia were compared in terms of presence of NARDS diagnosis based on the Montreux Definition.

Background/aims: Cholecystectomy for gallbladder (GB) polyps is performed primarily based on preoperative images. This study examined the accuracy of surgical indications commonly used in clinical practice for detecting neoplastic polyps and investigated further clues for predicting neoplastic polyps.
Methods: This retrospective study included 385 patients who underwent a cholecystectomy for GB polyps.

Hematological parameters available on automated hematology analyzers have been shown to be useful indicators for hematological disorders. However, extensive studies especially in aplastic anemia for these indices are sparse. Our aim was to investigate the clinical utility of hematological parameters in aplastic anemia.

Hepatitis B virus (HBV)-hepatitis delta virus (HDV) coinfection is the most severe form of chronic viral hepatitis, but the factors that determine disease progression and severity are incompletely characterised. This long-term follow-up study aims to identify risk factors for severe liver-related outcomes. In this multicentre national cohort study, data from admission until the last visit between 2001 and 2023 was retrospectively collected from 162 HBV-HDV coinfected patients.
