Acute adrenal failure due to bilateral adrenal haemorrhage is rare and may initially present with non-specific symptoms. It can rapidly progress into a life-threatening condition if not diagnosed promptly. Both traumatic and non-traumatic conditions have been implicated in the aetiology, with the latter been even rarer. We describe the case of a 57-year-old woman presenting with vomiting and epigastric pain and later developing fever and diarrhoea. The patient then deteriorated into shock and primary adrenal insufficiency was identified. A computed tomography scan noted bilateral adrenal haemorrhage. Further investigations showed a sigmoid colon adenocarcinoma and a myelodysplastic syndrome, with monosomy seven. Bilateral non-traumatic adrenal haemorrhage is an infrequent finding and investigating its aetiology can be challenging. In our patient, two simultaneous underlying diseases were identified. To the best of our knowledge, the combination of these two non-traumatic conditions as a cause of acute bilateral adrenal haemorrhage has not been previously reported. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusions Subcutaneous immunotherapy has emerged as an effective option for treating allergic diseases. Here, we assessed the clinical impact of the mannan‐conjugated birch pollen polymerized allergoid T502 in birch pollen‐induced allergic rhinoconjunctivitis.In this prospective, randomized, double‐blind placebo‐controlled phase III trial, 298 birch pollen–allergic adult patients were treated across 28 trial sites in Germany. Patients received either placebo or 23,000 mTU T502 subcutaneously over five pre‐seasonal visits. Efficacy was assessed by comparing the combined symptom and medication score (CSMS) between placebo and T502 during the peak birch pollen season 2022. Safety, tolerability and immunologic effects were also analyzed.During the peak birch pollen season, the median CSMS of the T502 group was reduced by 33% (p = 0.002) compared to placebo. The median daily symptom score and daily medication score were reduced by 30.4% (p < 0.001) and 56.3% (p = 0.045), respectively. Health related quality of life improved as reflected by reduction of RQLQ values by 31.5% (p < 0.0001). Production of Bet v 1 sIgG4 and Bet v 1 sIgG increased up to 6.2‐fold and 3‐fold respectively in the T502 group (p < 0.0001). The sIgE/sIgG4 ratio was strongly reduced in the T502 group at V7 (−62.9%, p < 0.0001).No fatalities nor serious adverse events were reported. In total, 16 systemic allergic reactions occurred (Grade I/II).Treatment with T502 significantly reduced symptoms and medication need in rhinoconjunctivitis patients. The treatment is well tolerated and safe. [ABSTRACT FROM AUTHOR]
