Immediate drug hypersensitivity reactions (IDHRs) pose significant diagnostic challenges, often requiring potentially hazardous drug challenge testing (DCT). Recent studies have indicated that flow cytometry-based cellular tests, including the basophil activation test (BAT), the mast cell activation test (MAT), and the T cell activation test (TAT), offer a promising alternative to reduce DCT reliance. While these tests are still in development, they demonstrate potential to compete with skin tests by providing superior diagnostic performance and improved patient safety by reducing the need for DCT. Moreover, it is encouraging that these flow cytometry-based tests are also suitable for challenging populations, such as children. Despite requiring specialised infrastructure, these tests have the potential to be cost-effective when performed in reference centres and may offer unique mechanistic insights into immediate drug hypersensitivity reactions. However, further research is required to validate their reliability, address pharmaceutical-specific testing considerations, and potentially integrate them into clinical guidelines.

Pollens are among the main seasonal allergens that trigger allergic respiratory diseases, which represent a real public health challenge worldwide. In Morocco, several studies have been conducted to identify the most involved pollens and the associated respiratory diseases. The review of clinical studies published from 2000 to 2025 confirms the dominance of olive tree and grasses at the top of pollen allergens in Morocco. Other pollens, such as cypress, Parietaria, Artemisia, mimosa, and date palm, have shown significant allergenic power but only locally. This distribution is mainly influenced by floristic richness, climate, and air pollution. Allergic rhinitis is the most common response to all pollens, often accompanied by asthma, followed by conjunctivitis and, in some cases, urticaria. Another range of pollens tested only in Casablanca or revealed through surveys deserves further study. Moreover, other chronic diseases reported in these same surveys require clinical investigations. This will help optimize the management and care of allergic respiratory diseases, particularly those triggered by pollens.

We describe a rare case of DRESS syndrome in a 55-year-old patient who was hospitalized for a cardiac arrhythmia requiring the introduction of acenocoumarol. Three weeks after taking acenocoumarol, the patient developed a generalized morbiliform maculopapular exanthema, surmounted by petechial purpuric lesions on the back, trunk and both lower limbs, associated with facial edema and a fever of 38.1°, with no clinically palpable adenopathies. Biological tests revealed hypeosinophilia and major hepatic cytolysis. According to the REGISCAR (Registry of Severe Cutaneous Adverse Reaction) score at 5 based on the clinical and biological aspects concomitant with drug intake, we retained the diagnosis of DRESS syndrome induced by acenocoumarol intake. The patient was treated with oral and topical cotricotherapy with good clinical and biological improvement.
我们描述了一例罕见的DRESS综合征,患者为55岁,因心律失常住院,需要使用阿塞诺古玛罗。服用阿塞诺古美尔3周后,患者出现全身性病状黄斑丘疹,背部、躯干及双下肢出现点状紫癜性病变,伴有面部水肿,发热38.1°,临床无可触及的腺病。生物学试验显示嗜酸性细胞增多和肝细胞溶解。根据REGISCAR (Registry of Severe Cutaneous Adverse Reaction,严重皮肤不良反应登记)基于药物摄入的临床和生物学方面评分为5分,我们保留了阿塞诺古玛罗摄入引起的DRESS综合征的诊断。患者经口服和局部cotrictherapy治疗,临床和生物学均有良好改善。

Stevens-Johnson Syndrome is a severe mucocutaneous disease that frequently arises in response to medications and is rarely observed. To our knowledge, we report the first pediatric case of SJS induced by Eculizumab, documenting the potential risks associated with this treatment in children and making a significant contribution to the medical literature. A three-year old male patient diagnosed with atypical hemolytic uremic syndrome and treated with Eculizumab exhibited classical symptoms of SJS shortly after receiving his fourth dose. These symptoms included severe oral and labial ulcers, conjunctival hyperemia, and extensive erythematous macular rashes. Initial laboratory tests revealed an abnormal white blood cell count and elevated inflammatory markers, with a subsequent skin biopsy confirming SJS. Immediate initiation of intravenous steroid therapy resulted in substantial improvement in the patient. This report underscores the critical importance of early recognition and management of SJS, particularly in pediatric patients receiving monoclonal antibody therapy. The key lessons highlight the need for healthcare providers to remain vigilant about this rare but potentially fatal adverse effect, and to promptly discontinue treatment and intervene effectively to improve patient outcomes.

Serum sickness-like reaction (SSLR) is a rare, non-IgE-mediated hypersensitivity reaction typically occurring in early childhood, characterized by nonspecific symptoms such as rash, fever, and joint involvement. Although symptoms generally emerge 5–21 days after drug exposure, earlier onset may occur in sensitized individuals upon repeated exposure to the same agent. We report the case of a 5-year old boy who developed fever, erythema, and extremity pain within 12 hours of a drug provocation test (DPT) with amoxicillin-clavulanic acid (ACA). A second DPT performed one month later triggered similar symptoms within 3 hours, confirming the diagnosis of SSLR. Laboratory findings supported systemic inflammation, and the symptoms resolved with corticosteroid treatment. This case highlights the variability in SSLR symptom onset and emphasizes the potential utility of DPT in selected cases to confirm the diagnosis and avoid unnecessary drug elimination. It also draws attention to the need for careful patient selection and standardized protocols when performing DPT in suspected SSLR.

This article is a non-systematic review on the epidemiology and burden of peanut allergy. Peanut allergy is one of the most common IgE-mediated food allergies in children, with an estimated prevalence in France of 0.9% at the age of 5.5 years based on questionnaires from the ELFE cohort. Peanut allergy begins in 90% of cases before the age of 3 years and spontaneously regresses in only 20 to 25% of cases before adulthood. Peanut allergy is associated with sensitization to one or more other legumes in two thirds of cases, and sometimes with a cross-allergy. Patients with peanut allergy most often have associated atopic comorbidities, particularly asthma. Peanut is one of the most common allergens involved in severe and even fatal food anaphylaxis and is associated with a high risk of allergy recurrence. Peanut allergy leads to impaired quality of life and has a significant psychosocial impact. Peanut-allergic patients probably have a different phenotype than patients with other food allergies. Multidisciplinary care and a personalized treatment strategy should be considered in these patients.

Fluorescein retinal angiography is a very well tolerated test; however adverse reactions of various severity have been reported, ranging from simple nausea to anaphylactic shock. Nausea, followed by vomiting are the most common anaphylactic incident after fluorescein injection. Premedication is sometimes indicated for patients at risk. Some authors propose desensitization protocols before carrying out an examination, while others propose as an alternative a retinal angiography with oral fluorescein, and sometimes the use of OCT (optical coherence tomography), or OCT-A (optical coherence tomography angiography). Finally, for more safety, it is important to equip the examination room with the necessary tools to manage this type of reactions. We report a retrospective study of 4 cases of adverse reaction following the injection of fluorescein for retinal angiography.
