DWP16001 is a novel sodium-glucose cotransporter-2 (SGLT2) inhibitor under development for the treatment of type 2 diabetes mellitus. This study was conducted to evaluate the pharmacokinetics (PK), pharmacodynamics (PD), and safety of DWP16001 after single and multiple doses in healthy subjects. A randomized, double-blind, placebo- and active-controlled, single- and multiple-dose study was conducted. Twelve subjects in each dose group received a single dose (0.2, 0.5, 1.0, 2.0, or 5.0 mg) or multiple doses (0.1, 0.3, 0.5, 1.0, or 2.0 mg once daily for 15 consecutive days) of DWP16001, dapagliflozin 10 mg, or placebo, in a ratio of 8:2:2. Serial blood samples and interval urine samples were collected for PK and PD analyses. Safety and tolerability were assessed throughout the study period. A dose-dependent increase in urinary glucose excretion (UGE) was observed after a single dose, and the steady-state UGE was 50–60 g/day after multiple doses in the dose range of 0.3 – 2.0 mg. DWP16001 was rapidly absorbed with the time to peak plasma concentration of 1.0 – 3.0 hours, and eliminated with a mean elimination half-life of 13 - 29 hours. The systemic exposure of DWP16001 increased proportionally with the dose after multiple administrations in the range of 0.1 – 2.0 mg. DWP16001 was well tolerated in all dose groups. DWP16001 caused glucosuria in a dose-dependent manner, and systemic exposure was observed after multiple doses. DWP16001 was well tolerated up to 5.0 mg after a single oral dose and up to 2.0 mg after multiple oral administration

Coronavirus disease 2019 (COVID-19) is a viral disease caused by a novel coronavirus that can lead to severe acute respiratory failure. Recent studies have shown that aggravating factors in the etiology of COVID-19 disease include genetic defects and autoantibodies against type 1 interferon. Mycobacterium tuberculosis is an immobile aerobic bacillus that causes tuberculosis disease. SARS-CoV-2 infection and immunosuppressive drugs may temporarily inhibit immunologic system, then may lead to active tuberculosis by reactivation or infection of M. tuberculosis. We aimed to show that there is a relationship between covid-19 infection and an increase in the number of tuberculosis patients. Eight patients diagnosed with tuberculosis in the Pediatric Pulmonology and Pediatric Infectious Diseases Clinics of Necmettin Erbakan University, Meram Medical Faculty between March 2020 and May 2021 were enrolled in this study. The presence of COVID-19 infection was confirmed by COVID-19 antibody test and patient’s detailed medical history. The patient with negative antibody test was also included in the study if other family members confirmed for COVID-19 infection by RT-PCR. We evaluated demographic data, laboratory findings, imaging tests and pathology results of all patients. The remarkable increase in the number of tuberculosis activation in the recent year suggests the role of COVID-19 infection. The pathologic structure of the virus may be responsible of the increase, although the mechanism is not fully understood. Further research should be done on this topic.
