| Summary: | Background: We report the first case of cimetidine as an alternative adjuvant therapy in a pregnant woman with recurrent respiratory papillomatosis (RRP). A 40 year old woman at 19 week gestation presented with progressive hoarseness and shortness of breath for 1 month. Flexible nasopharyngolaryngoscopy revealed multiple papillomatous lesions over both vocal cords and subglottic area obstructing 60 of her airway. She had previously been diagnosed with juvenile onset RRP at the age of 5 and underwent endoscopic clearance regularly every 6 months. Method: The patient was started on a trial of oral cimetidine at a dose of 30 mg/kg and responded well, eventually requiring endoscopic excision only after 2 years. Subsequently, she underwent in vitro fertilisation treatment and stopped taking her cimetidine. After undergoing endoscopic clearance of her papillomata under general anaesthesia, she restarted on cimetidine during her 2nd and 3rd trimester. Results: Ensuing follow-up demonstrated stable minimal papillomata lesions on her right inferior surface of her vocal cord with no recurrence on her left vocal cord and subglottic area. Conclusion: Cimetidine is generally safe and not known to be associated with any major teratogenic risks during pregnancy. RRP is postulated to worsen in pregnant women due to the increase in oestrogen levels during pregnancy. Hence, adjuvant therapy was imperative for our patient to reduce recurrent papillomata formation during her pregnancy. Larger scale studies are warranted to assess the use of long-term high-dose cimetidine in terms of efficacy and safety in pregnancy. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature. |
