However, design of CARs as well as the antigens chosen to be their targets  are constantly being changed in order to improve the efficacy of this therapeutic strategy. CAR-T therapy for DLBCL, NOS has been used on patients who are refractory to and/or have progressed on first-line as well as salvage (including autologous stem cell transplantation) treatment regimens. Patients are treated first with a conditioning chemotherapy regimen, usually cyclophosphamide and fludarabine, and then infused with their own T-cells that have been engineered to attack CD19-bearing or, rarely, CD20-bearing cells. A meta-analysis of 17 studies using this or very similar approaches to treat DLBCL, NOS found the treatments gave complete and partial responses rates of 61% and 43%, respectively. While these studies did not have control groups and were too recent for meaningful estimates of remission durations, the remission rates were higher than expected using other treatment approaches. Significant and potentially lethal therapeutic complications of this therapy included development of the cytokine release syndrome (21% of cases), neurotoxicity, i.e. the CAR-T cell-related encephalopathy syndrome (9% of cases), and the hemophagocytic lymphohistiocytosis/macrophage-activation syndrome (i.e. a form of Hemophagocytic lymphohistiocytosis). Individual studies within and outside of this meta-analysis have reported remissions lasting >2 years but also lethal cytokine release syndrome and neurotoxicity responses to this therapy. As a consequence of these studies, the Committee for Advanced Therapies and the Committee for Medicinal Products for Human Use of the European Medicines Agency recommend granting marketing authorization for tisagenlecleucel (i.e.
Women with chronic endometritis are also at a higher risk of pregnancy loss and treatment for this improves future pregnancy outcomes.Chronic granulomatous endometritis is usually caused by tuberculous. The granulomas are small, sparse, and without caseation. The granulomas take up to 2 weeks to develop and since the endometrium is shed every 4 weeks, the granulomas are poorly formed. In human medicine, pyometra (also a veterinary condition of significance) is regarded as a form of chronic endometritis seen in elderly women causing stenosis of the cervical os and accumulation of discharges and infection. Symptom in chronic endometritis is blood stained discharge but in pyometra the patient complaints of lower abdominal pain. Pyometra
Pyometra describes an accumulation of pus in the uterine cavity. In order for pyometra to develop, there must be both an infection and blockage of cervix. Signs and symptoms include lower abdominal pain (suprapubic), rigors, fever, and the discharge of pus on introduction of a sound into the uterus. Pyometra is treated with antibiotics, according to culture and sensitivity. See also
