Acute porphyrias – A neurological perspective

Brain and Behavior, 2021
Acute hepatic porphyrias (AHP) can cause severe neurological symptoms involving the central, autonomic, and peripheral nervous system. Due to their relative rarity and their chameleon‐like presentation, delayed diagnosis and misdiagnosis are common. AHPs

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Red lines and green lights: Gene therapy for inherited erythroid disorders beyond the haemoglobinopathies

British Journal of Haematology, EarlyView.
Gene therapy is revolutionizing treatment paradigms for haemoglobinopathies, establishing a translational framework for disorders that impact red blood cell development. In their paper, Joshi et al. describe the preclinical and early clinical landscape of gene therapies for non‐haemoglobinopathy erythroid disorders and highlight common thematic ...

Tolerability of hormonal treatments in acute hepatic porphyria patients

Internal Medicine Journal, EarlyView.
Abstract Background Acute hepatic porphyria (AHP) flares have been associated with female hormones and the use of hormonal treatments. Women with AHP are traditionally advised to avoid exogenous oestrogen and progesterone, limiting options for contraception and management of menorrhagia, dysmenorrhoea and menopausal symptoms.

Nucleotide Metabolism in Health and Disease

MedComm, Volume 7, Issue 8, August 2026.
Nucleotide metabolism, including de novo synthesis, salvage pathways, and catabolism, when dysregulated contributes to cancer, immune disorders, metabolic and urological diseases, and radiation injury. Metabolites such as adenosine, cGAMP, NAD, and cAMP and enzymes like RNR are promising therapeutic targets and biomarkers.

Iron Overload: Pathophysiology, Diagnosis and Monitoring

International Journal of Laboratory Hematology, Volume 48, Issue 4, Page 747-756, August 2026.
ABSTRACT Iron overload is associated with significant health risks, underscoring the importance of understanding its pathophysiology as well as establishing accurate diagnostic and monitoring methods. Chronic iron overload is associated with either genetic disorders characterized by excessive iron accumulation (hereditary hemochromatosis), or is ...
