This effect may be the cause of conception early after the first doses of mepolizumab treatment. Related ISCK03 to glucocorticoid hypothesis, pressure induced improved serum endogenous glucocorticoid concentration may cause reproductive dysfunction. method (withdrawal,condom) for years, she did not get pregnant until receiving the second dose of mepolizumab treatment. Result Two ladies were treated with mepolizumab for eosinophilic severe asthma and they got pregnant. Summary Unexplained infertility in people with severe eosinophilic asthma may be corrected by mepolizumab treatment. However, there is not enough data concerning the use of mepolizumab during pregnancy. fertilization) treatment was postponed because of severe asthma attacks. Mepolizumab was started, considering the patient as having severe asthma. After 1st dose of mepolizumab, eosinophil level, PEF and FEV1 were 100 cell/mcL (1.2%), 73 lt/min, 73% respectively. Asthma control test score was 24. No side effects were seen. Before the third dose of mepolizumab treatment, she experienced pregnancy of 5?weeks gestational age. She decided to give birth despite the difficulty of the situation. Mepolizumab treatment was ended because there are insufficient data regarding the use of mepolizumab during pregnancy. She started to get 32?mg of prednisone treatment at the end of 12?weeks. Actually receiving high dose steroid and LABA treatment, she experienced 2 severe attacks during her pregnancy. Due to improved severity of asthma (Take action 8), dyspnoea, cough and eosinophil level of 1800 cell/mcL (24%), she restarted to receive mepolizumab treatment after giving birth. Her dyspnoea was improved, and Take action score is increased to 21 although cessation of steroid treatment by herself. The pregnancy was ended up with a healthy baby without any congenital anomalies. Case 2 A 36-year-old married female with three children did not possess any pregnancy. She experienced rhinitis for 6?years, asthma for 4?years and smoking history. Pores and skin prick test for inhalant allergens and specific IgE for inhalant allergens (mixture of mite, mould and grasses) were negative. High resolution computed tomography showed mosaic parenchymal pattern and pleuroparenchymal sequela changes were recognized in the apex of the remaining lung. A few millimetre sized nodules were detected in the right and remaining lung. Anti-neutrophilic cytoplasmic antibody (ANCA), anti-nuclear antibody (ANA) results were bad. Eosinophil level, total IgE, FEV1, PEF and Take action were 600 cell/mcL (6.7%), 32?IU/ml, 53%, 49 lt/min and 12, respectively. We started mepolizumab treatment, and after the 1st dose, eosinophil level was decreased to 100 cell/mcL (1.4%), and Take action score, FEV1 and PEF were improved to 20, 78.8% and 77 lt/min, respectively. Although she used the same contraception method (withdrawal,condom) for years, she did not get pregnant until receiving the second dose of mepolizumab treatment. She decided to terminate pregnancy because of unfamiliar effects of mepolizumab within the foetus. Conversation Asthma is one of the most common chronic inflammatory airway disease among reproductive period in ladies [1]. Although there are contradictory results in different studies, asthma is generally considered to be a disease resulting in decreased fertility [7C9]. In addition, time to pregnancy has been shown to ISCK03 be decreased by asthma treatment which supports the hypothesis of reduced fertility in asthma [10]. There are a few hypotheses for the explanation of decreased fertility in asthma including asthma related chronic swelling, chronic use of OCS and stress induced by frequent exacerbations of asthma and decreased quality of life. Our individuals with severe eosinophilic asthma became pregnant after receiving mepolizumab treatment with normal eosinophil count. This may be due to the effect of mepolizumab on eosinophils and asthma control. Eosinophil count is known to be associated with asthma related swelling and ISCK03 the severity of asthma [11]. Asthma may cause swelling in additional systems including reproductive system through chronic Th 2 (T helper, eosinophilic) swelling [12]. Gade et?al. [13] have been suggested that endometrium might have inflammatory changes. They showed that vascular endothelial growth factor (VEGF) levels decreased in uterine endometrial secretions in asthmatic individuals. This decrease in VEGF may result in prolongation of time to pregnancy. Asthma may switch sex steroid hormone levels and cause Rabbit Polyclonal to NRIP2 irregular menses [14]. Another hypothesis of infertility in severe asthma is definitely chronic use of OCS. It is known that exogenous glucocorticoid treatment affects the hypothalamo-pituitary- gonadal (HPG) axis and suppresses the reproductive function. This effect may be due to direct influence of glucocorticoids on hypothalamic receptors or gonads [15C17]. It has been demonstrated that mepolizumab offers OCS sparing effect by reducing exacerbations and improving the symptoms of astma [4]. In our individuals, mepolizumab improved the symptoms of.
