Pregnancy-associated atypical haemolytic uraemic syndrome is a rare and potentially lethal complement-mediated disorder. It can mimic preeclampsia, gestational hypertension, thrombotic thrombocytopenic purpura and hemolysis, elevated liver enzymes and low platelets syndrome. Thus, it can be hard to distinguish pregnancy-associated atypical haemolytic uraemic syndrome from other causes in peri/post-partum women presenting with features of microangiopathic haemolytic anemia, thrombocytopenia and acute kidney injury.

Purpose: To evaluate the level of eosinophil count in Covid-19 pregnant patients as a cost-effective tool for aiding in diagnosis, differential diagnosis, and prognosis and, to assess whether eosinopenia could be similar or superior to lymphopenia in pregnancy with Covid-19.

Methods: Retrospective case-control study was conducted including pregnant women tested simultaneously for SARS-CoV-2 by RT-PCR and complete blood count (CBC). Eosinophil counts (EOS), lymphocytes (LYM), neutrophils (NEU) with calculation of EOS/LYM ratio, EOS/NEU ratio, NEU/LYM ratio, LYM/NEU ratio (LNR), eosinopenia, and lymphopenia were compared between the groups.

Purpose: To investigate the effects of laboratory-confirmed SARS-CoV-2 infection on thyroid function tests (TFTs) in pregnant women and to evaluate whether TFT changes are related to the severity and prognosis.

Methods: Consecutive pregnant women tested for SARS-CoV-2 by RT-PCR at Ankara City Hospital were recruited between January 2021 and September 2021. Thyroid-stimulating hormone (TSH), free thyroxine (FT4) and free triiodothyronine (FT3), thyroid peroxidase antibody (anti-TPO), and thyroglobulin antibody (anti-TG) were measured on admission.
