To investigate in mice the mechanisms underlying renal functions in a type I diabetes model, we have suppressed B2 kinin receptors local activities by their specific antagonist D-Arg [Hyp3-Thi5-D-Tic7-Oic8]BK (HOE 140). Mice made diabetic with low consecutive doses of streptozotocin (STZ) (45 mg/k BW during 5 days) were injected with HOE 140 (15 micrograms/twice a day) for 15 days. This drug did not modify glycemia of STZ treated animals but a significantly reduction of urinary proteins, nitrites and kallikrein was observed. These results indicate that kinin B2-receptors activation is implicated in the alterations of renal function in this model of type I diabetes in mice.

Idiopathic non-mast cell angioedema (INMA) is a rare disease typified by recurrent attacks of cutaneous and subcutaneous swelling. Every attack carries the potential for severe morbidity and, in the case of laryngeal involvement, mortality. Whereas therapies approved for hereditary angioedema (HAE) have been used in the care of patients with INMA, little is known with regard to their efficacy for the treatment of this disease.

Over the past two decades, guidelines for the on-demand treatment of hereditary angioedema (HAE) attacks have undergone significant evolution. Early treatment guidelines, such as the Canadian 2003 International Consensus Algorithm, often gated on-demand treatment by attack location and/or severity. Pivotal trials for on-demand injectable treatments (plasma-derived C1 esterase inhibitor [C1INH], icatibant, ecallantide [US only], recombinant C1INH), which were approved in the US and EU between 2008-2014, were designed accordingly.

Communications between different cell types within a tissue are often critical for the proper functioning of an organ. In the central nervous system, interactions among neurons and glial cells are known to modulate neurotransmission, energy metabolism, extracellular ion homeostasis, and neuroprotection. Here we showed that bradykinin, a proinflammatory neuropeptide, can be detected by astrocytes, resulting in the secretion of cytokines that act on neurons.

Introduction: Hereditary angioedema (HAE) is a rare genetic disease characterized by recurrent, potentially life-threatening angioedema episodes. Despite its severity, including the risk of asphyxiation, HAE often remains underdiagnosed. The disease significantly impacts patient quality of life (QoL), leading to anxiety, depression, and avoidance behaviors due to the unpredictable nature of attacks.

Background And Objectives: Patients with rare diseases like hereditary angioedema (HAE) are usually referred to an angioedema center to ensure guideline-compliant and experience-based therapy. Even though there are established guidelines and several approved therapeutics, there are still open questions and situations in the daily care of HAE patients, where an exchange between centers is needed.
Materials And Methods: A survey was conducted among physicians from German angioedema centers regarding challenges and issues in everyday HAE treatment.
