Background: Laboratory Animal Allergy (LAA) has been considered a risk for the workers since 1989 by the NIOSH. About one third of the Laboratory Animal Workers (LAWs) can manifest symptoms to LAA as asthma, rhinitis, conjunctivitis and cutaneous reactions. The prevalence of LAA-induced clinical symptoms has been estimated with a great variability (4-44%) also due to the different methodologies applied.
Objective: Evaluate the prevalence of IgE positivity to mouse and rat allergens in LAWs and assess which factors are predisposing to sensitization among subjects exposed to laboratory animals in the workplace.
Methods: One hundred LAWs were invited to fill out a questionnaire regarding current allergic symptoms, atopic history, home environment, previous and current occupational history. IgE reactivity specific allergens was evaluated with ImmunoCAP ISAC.
Results: Out of one hundred LAWs, 18% had a serum susceptibility to mouse and/or rat allergens and 42% reported to have occupational allergy symptoms. Combining the results acquired by ImmunoCAP ISAC and questionnaire, 17% of LAWs have been defined as LAWs-LAA positive since they present a positive IgE response and allergy symptoms, 1% LAWs-LAA sensitized, 25% LAWs-LAA symptomatic and 57% LAWs-LAA negative. Presence of previous allergy symptoms in work and life environment were significantly related to LAWs-LAA positive/sensitized.
Conclusions: The study aimed to define the immunological profile of LAWs using the proteomic array as an innovative approach in the study of environmental and occupational exposure to allergens. We suggested a definition of LAWs-LAA considering serum IgE response and presence of allergy symptoms. The proposed approach has the advantage to provide a standard methodology for evaluating the specific IgE responsiveness to animal allergens in specific workplace also considering the immunological profile of workers referred to exposure in life and occupational environment.

Parainfluenza virus 3 (PIV3) infection poses a substantial risk to vulnerable groups including infants, the elderly, and immunocompromised individuals, and lacks effective treatments or vaccines. This study focuses on targeting the hemagglutinin-neuraminidase (HN) protein, a structural glycoprotein of PIV3 critical for viral infection and egress. With the objective of targeting these activities of HN, we identified eight neutralizing human monoclonal antibodies (mAbs) with potent effects on viral neutralization, cell-cell fusion inhibition, and complement deposition.

Background & objectives Spirometric glycopyrronium responsiveness, a new advent, needs to be examined at in terms of degree and frequency in different obstructive-airway diseases diagnosed in real world practise. Methods Serial and willing symptomatic affected individuals of suspected airway disease underwent a pragmatic post-consultation spirometry-protocol on the same day with salbutamol followed by glycopyrronium bromide. The diagnosis of asthma (FEV1-reversibility ≥ 200 ml + 12%), chronic obstructive pulmonary disease (COPD) (FEV1/FVC<0.

Background: Allergic bronchopulmonary aspergillosis/mycosis (ABPA/M) is a complex non-infectious pulmonary benign disease characterized by an immune response against aspergillus/fungus. Carcinoembryonic antigen (CEA), typically recognized as a tumor marker, also elevated in certain benign diseases. Few studies on ABPA/M cases presenting with elevated serum CEA levels have been reported.

Giant cell arteritis (GCA) is a large vessel vasculitis with cranial and extracranial vessel involvement. Clinicians suspect GCA when a patient exhibits symptoms or exam findings of temporal headache with sudden vision loss, jaw or tongue claudication, scalp tenderness, abnormal temporal artery exam, and diagnostic findings, including elevated inflammatory markers. We present a case, which highlights that, despite established diagnostic measures, challenges persist.
