Abstract
Ropivacaine is an amide local anesthetic with rare reports of anaphylaxis. To our knowledge, this is the first report of delayed nonimmune anaphylaxis induced by ropivacaine. A 70-year-old man underwent general anesthesia with a nerve block for a total knee arthroplasty. The patient developed symptoms of anaphylaxis 3.5 hours after receiving ropivacaine for femoral and tibial nerve blocks. A basophil activation test (BAT) revealed ropivacaine as the causative agent. Notably, anaphylaxis can be caused by medications even hours after their administration, and all administered drugs should be suspected of potentially causing anaphylaxis.

Diagnostic utility of the basophil activation test in natto-induced hypersensitivity. Allergol Int 2022; 71:125-130. [PMID: 34393037 DOI: 10.1016/j.alit.2021.07.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Revised: 06/27/2021] [Accepted: 06/28/2021] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Natto (fermented soybeans)-induced hypersensitivity is characterized by delayed symptom onset that hampers diagnosis. We aimed to clarify the clinical utility of the basophil activation test (BAT) in the diagnosis of natto-induced hypersensitivity. METHODS Five patients with a history of anaphylaxis and chronic urticaria suspected of natto-induced hypersensitivity and seven with chronic spontaneous urticaria clinically unrelated to natto were enrolled in the patient and control groups, respectively. The BAT was performed with two incubation times, 15 min and 1 h, in combination with various concentrations of natto-mucilage extract. RESULTS In controls, CD203c levels in basophils remained low in the 15-min incubation but were significantly increased in the 1-h incubation. In the patient group, in the 15-min condition, basophil CD203c was significantly upregulated by natto mucilage but not by soybean vs controls (P = 0.001). Low concentrations of natto mucilage were sufficient to upregulate basophil CD203c in the anaphylaxis cases, but high concentrations were required to induce the same effect in the urticaria cases. Finally, the dose-dependent pattern of the BAT results differed significantly between the anaphylaxis and urticaria cases (P = 0.006). Thus, a strong background reaction was observed in the BAT with 1 h incubation; 15 min of incubation was sufficient to identify patients with natto-induced hypersensitivity and may distinguish the clinical phenotype of natto-induced hypersensitivity, i.e., anaphylaxis or urticaria. CONCLUSIONS The BAT with a 15-min incubation period is useful in diagnosing natto-induced hypersensitivity.

Mannose-binding lectin and its roles in immune responses in grass carp (Ctenopharyngodon idella) against Aeromonas hydrophila. FISH & SHELLFISH IMMUNOLOGY 2018; 72:367-376. [PMID: 29129586 DOI: 10.1016/j.fsi.2017.11.013] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2017] [Revised: 11/06/2017] [Accepted: 11/07/2017] [Indexed: 06/07/2023]
Abstract
The complement system is a crucial component of the innate immune system that links innate and adaptive immunity via four pathways. Mannose-binding lectin (MBL), the initiating molecule of the lectin pathway, plays a significant role in the innate immune system in mammals and fish. Herein, we identified an MBL homolog (gcMBL) in grass carp (Ctenopharyngodon idella). The full-length 948 bp gcMBL cDNA includes a 741 bp open reading frame encoding a 246 amino acid protein with a signal peptide, collagen triple helix repeat domain, and a C-type lectin-like/link domain. The gcMBL protein shares low similarity with MBL counterparts in other species, and is most closely related to Cyprinus carpio MBL. Transcription of gcMBL was widely distributed in different tissues, and was induced by Aeromonas hydrophila in vivo and in vitro. Expression of gcMBL was also affected by LPS and flagellin stimulation in vitro. In cells over-expressing gcMBL, transcripts of almost all components except gcC5 were up-regulated, and gcMBL, gcIL1β, gcTNF-α, gcIFN, gcCD59, gcC5aR and gcITGβ-2 were significantly up-regulated following exposure to A. hydrophila or stimulation by bacterial PAMPs. Meanwhile, gcMBL deficiency achieved by RNAi down-regulated transcript levels following A. hydrophila challenge, and gcMBL induced NF-κB signalling. These findings indicate a vital role of gcMBL in innate immunity in grass carp.
