Background: Triple-negative breast cancer (TNBC) has none of the targeted treatment choices due to its distinct biological property, making this subtype a unique disease. In this study, we evaluated the impact of obesity on clinical outcomes of TNBC. Methods: The data of breast cancer patients admitted to our department were collected. TNBC was defined as lack of estrogen receptor (ER), progesterone receptor (PR) and HER-2. The body mass index (BMI) of 112 TNBC patients was calculated with weight at the time of diagnosis and height. The patients were classified into groups with a BMI of < 25 (normal/underweight), 25-29.9 (overweight) or ≥ 30 (obese). After a mean follow-up of 23.2 ± 15.5 months, there were 12 recurrences (10.71%) and 6 deaths (5.35%). Disease-free survival (DFS) and overall survival (OS) were assessed. Results: The survival analyses of all the patients did not demonstrate any differences in OS or DFS in obese as compared to non-obese patients. However, we showed that obesity was associated with a poorer OS for postmenopausal TNBC patients (p < 0.05). Conclusion: Obesity is related to a poorer OS in postmenopausal TNBC patients. Due to the heterogeneous disease profile of TNBC, larger randomized studies will be needed to clarify the exact role of obesity in TNBC.

<b><i>Introduction:</i></b> The COVID-19 pandemic has caused a global health crisis. To prevent the disease, the Ministry of Health of Turkey gained approval for the CoronaVac COVID-19 vaccine for emergency use as the first-line. This study aimed to evaluate patients who developed hypersensitivity reactions (HRs) due to the CoronoVac vaccine and to share our experience of administering the second dose of vaccine to these patients. <b><i>Methods:</i></b> The study group included the patients who presented to the Ege University Allergy and Immunology Division between January and May 2021. Demographic data, atopic status, allergic reactions to the first dose of the COVID-19 vaccine and the route of second-dose vaccine administrations were recorded. <b><i>Results:</i></b> A total of 7 patients (four healthcare professionals), 6 (86%) of whom were women, with an average age of 53.4 years, were included in the study. The rate of allergic reactions among Ege University health workers was 0.036% (2/5,558). Six of our patients had a history of additional allergic diseases and comorbid diseases. None had any allergic reactions to previous vaccinations and latex allergy. Reactions developed commonly on the skin, as generalized urticaria/angioedema and pruritus. The severity of the reactions was evaluated as mild in 2, moderate in 3, and severe in 2 cases. The second-dose CoronaVac was safely administered by using a gradually increase dose in a total of 6 patients. <b><i>Conclusion:</i></b> In patients with HRs due to Sinovac in the first dose, the second dose can be safely performed using a gradually increased dose.

Hereditary angioedema due to C1-inhibitor deficiency (C1-INH-HAE) is a rare, autosomal dominant disorder. The management of pregnant patients with C1-INH-HAE is a challenge for the physician. Intravenous plasma-derived nanofiltered C1-INH (pdC1INH) is the only recommended option throughout pregnancy, postpartum, and breastfeeding period. In order to increase pregnancy rates, physicians use fertilization therapies increasing endogen levels of estrogens. Therefore, these techniques can provoke an increase in the number and severity of edema attacks in C1-INH-HAE. Our patient is a 32-year-old female, diagnosed with C1-INH-HAE type 1 since 2004. She had been taking danazol 50–200 mg/day for 9 years. Due to her pregnancy plans in 2013, danazol was discontinued. PdC1INH was prescribed regularly for prophylactic purpose. Triplet pregnancy occurred by in vitro fertilization using luteinizing hormone-releasing hormone (LHRH) injections. In our patient, LHRH injections were done four times without causing any severe attack during in vitro fertilization. Angioedema did not worsen during pregnancy and delivery due to the prophylactic use of intravenous pdC1INH in our patient. According to the attack frequency and severity, there was no difference between the three pregnancy trimesters. To our knowledge, this is the first published case of C1-INH-HAE receiving in vitro fertilization therapies without any angioedema attacks during pregnancy and delivery and eventually having healthy triplets with the prophylactic use of intravenous pdC1INH.
