ABSTRACT
INTRODUCTION: Autoimmune thyroid disease (AITD) with elevated anti-thyroid peroxidase antibody (aTPO) levels appears in 12-25% of all women, apart from thyroid dysfunction. High titers of aTPO are more common in women with polycystic ovary syndrome and endometriosis. Elevated aTPO has been associated with infertility and poorer quality of life among euthyroid women, and may be related to other factors. OBJECTIVES: The aim of the study was to measure differences in serum leptin concentration between AITD+ and AITD- patients. Setting, patients and main outcome measures: The sample was comprised of 74 women who were hospitalized in the Department of Gynecological Endocrinology, Medical University of Warsaw. Data collected included age, body mass index (BMI), and serum aTPO, serum thyroid stimulating hormone (TSH), serum fT4, serum follitropin (FSH), serum estradiol and serum leptin. AITD positive status was defined as serum aTPO greater than 5.6 mIU/ml. RESULTS: Serum leptin concentrations were significantly higher in AITD+ patients compared to AITD- patients (17.13 ng/ml [SD 7.66] versus 12.78 ng/ml [SD 7.28]; p < 0.05). No differences by AITD status were found in age, BMI, TSH, FSH, estradiol and fT4. CONCLUSIONS: Serum leptin concentrations were higher in patients with AITD than in patients without AITD.

INTRODUCTION: Tumor regression grades (TRGs) quantify the pathologic response to neoadjuvant chemotherapy (NAC). The aim of the study was to investigate the prognostic value of TRGs in combination with the TNM classification in an independent cohort of patients with muscle-invasive bladder cancer (MIBC) treated with NAC followed by radical cystectomy (RC) in a retrospective setting. PATIENTS AND METHODS: Patients treated with a complete course of NAC followed by RC for MIBC between December 2012 and December 2017 were enrolled in the study. TRGs were determined in RC specimens. Data were collected preoperatively, and the follow-up was continued up to August 2018. Kaplan-Meier curves and the Cox proportional hazards model were used to compare survival probabilities between major responders (no MIBC, < ypT2 and ypN0), partial responders (≥ ypT2 or ypN+ and TRG2), and non-responders (≥ ypT2 or ypN+ and TRG3). RESULTS: A group of 70 patients with a median age of 64 years (interquartile range, 58-67 years) was analyzed. There were 36 major responders, 21 partial responders, and 13 non-responders. In comparison with a major response, a partial response was associated with a hazard ratio of 9.44 (95% confidence interval, 1.10-80.89; P = .04) and non- responders showed a hazard ratio of 17.85 (95% confidence interval, 2.18-145.85; P = .007) for death. CONCLUSIONS: The study confirms the prognostic value of the pathologic response to NAC. Determination of TRGs is straightforward, provides valuable information, and could be easily included in the standard pathologic examination of RC surgical specimen. Prospective studies are needed to establish the role of TRG in routine clinical practice.
