Aim. To report a clinical case of autoimmune/inflammatory syndrome, induced by adjuvants in patient after polypropylene mesh implantation for inguinal hernia repair. Materials and methods. Patient Z., male, 68 years old, was admitted to the hospital presenting muscle weakness and progressive dyspnoea. Interview and physical exam revealed signs of cognitive impairment and memory loss, proximal muscle weakness. Differential diagnosis was made to clarify genesis of symptoms, to rule out polymyositis, other systemic connective tissue diseases, oncologic diseases, hypothyroidism, infectious diseases. Results. Creatine kinase, thyroxine, thyreothropic hormone levels were normal. Clinical and immunological investigation revealed no data on polymyositis or any other systemic connective tissue disease. Yersiniosis, salmonellosis, malaria were ruled out. Chest CT scan, abdomen CT scan, gastroscopy, colonoscopy no data on the presence of malignant neoplasms. PSA level were normal. Electroneuromyography revealed signs of symmetrical axonal type damage to the motor portion of the ulnar nerves on both sides, and demyelinating type damage to the sensory portion. Prednisolone therapy was started at a dose of 40 mg per 24 hour (0.5 mg per kg), which lead to a significant clinical improvement. Based on the therapy response and positive diagnostic criteria (clinical manifestation after polypropylene mesh implantation, typical clinical manifestation – muscle weakness, chronic fatigue, cognitive impairment, neurological manifestations associated with demyelination) patient was diagnosed with autoimmune/inflammatory syndrome, induced by adjuvants (ASIA) after polypropylene mesh implantation for inguinal hernia repair. Conclusion. This clinical case report demonstrates possibility of a persistent course of the disease (symptoms were present for 15 years). Feature of this case is partial clinical improvement due to long-term uncontrolled dexamethasone use, which was prescribed empirically.
