Patient description: The patients is a 25-year-old G1 P1 pregnant woman who is 24W3D gestational old who developed a sudden unset of fever and chills, accompany with nausea and vomiting. She also complains of dysuria, urgency and frequency. She also reports some severe pain in the flank. Her vital signs are: T = 39.7ºC, P = 117, R = 20, and BP = 113/74 mm Hg. Physical examination reveals tenderness on palpation of both costovertebral angles. She has no history of recurrent UTI prior to her pregnancy or any other underlying disease. The urine culture showed Gram-negative rod-shaped bacterial cells, leukocytes, and leukocyte casts. The blood culture is negative. A CBC shows Hb 12.9 g/dL, Hct 39%, MCV 76 fL, WBC count 14,120/µL.

Clinical trial eligibility criteria: eligible ages (years): 18.0-73.0,  Lymphoma, Large-Cell, Anaplasitc Enteropathy-Associated T-Cell Lymphoma Lymphoma, Large B-Cell, Diffuse Lymphoma, Extranodal NK-T-Cell Lymphoma, T-Cell, Peripheral Malignancy Patients must have anaplastic large cell lymphoma, angioimmunoblastic T-cell lymphoma, peripheral T-cell lymphoma not otherwise specified, diffuse large B-cell lymphoma not otherwise specified, primary mediastinal B-cell lymphoma, grey zone lymphoma, enteropathy-associated T-cell lymphoma, or extranodal NK/T-cell lymphoma, nasal type Clear CD30 expression must be detected on 75% or more of malignant cells from either bone marrow or lymphoma mass by flow cytometry or immunohistochemistry. The patient s malignancy will need to be assessed for CD30 expression by flow cytometry or immunohistochemistry performed at the NIH. If unstained, paraffin-embedded bone marrow or lymphoma sections are available from prior biopsies, these can be used to determine CD30 expression by immunohistochemistry; otherwise, patients will need to come to the NIH for a biopsy to determine CD30 expression. The sample for CD30 expression can come from a biopsy obtained at any time before enrollment, unless the patient has received a prior anti-CD30 monoclonal antibody, in which case the sample must come from a biopsy following completion of the most recent anti-CD30 monoclonal antibody treatment Eligible patients with diffuse large B-cell lymphoma or primary mediastinal B-cell lymphoma must have received 2 prior treatment regimens at least 1 of which included an anthracycline and an anti-CD20 monoclonal antibody Patients must have measurable malignancy as defined by at least one of the below Lymphoma mass that is measurable (minimum 1.5 cm in largest diameter) by CT scan is required unless bone marrow lymphoma is detectable For a lymphoma mass to count as measurable malignancy, it must have abnormally increased metabolic activity when assessed by positron emission tomography (PET) scan For lymphoma with only bone marrow involvement, no mass is necessary, but if a mass is not present, bone marrow malignancy must be detectable by flow cytometry. Other Greater than or equal to 18 years of age and less than or equal to age 73 Able to understand and sign the Informed Consent Document  Patients with Hodgkin lymphoma are no longer eligible for participation (as of amendment G, Protocol version: 08/12/2019) Patients that require urgent therapy due to tumor mass effects or spinal cord compression Patients with lymphoma masses 10.0 cm or larger in longest diameter will not be eligible Patients that have active hemolytic anemia Patients who are currently taking any medications for systemic anticoagulation other than aspirin will not be eligible Patients with second malignancies in addition to their lymphoma are not eligible if the second malignancy has required treatment (including maintenance therapy) within the past 4 years or is not in complete remission. There are two exceptions to this criterion: successfully treated non-metastatic basal cell or squamous cell skin carcinoma Women of child-bearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the preparative chemotherapy on the fetus or infant. Women of child-bearing potential are defined as all women except women who are postmenopausal or who have had a hysterectomy. Postmenopausal will be defined as women over the age of 55 who have not had a menstrual period in at least 1 year Active uncontrolled systemic infections (defined as infections causing fevers and infections requiring intravenous antibiotics when the intravenous antibiotics have been administered for less than 72 hours); active coagulation disorders or other major uncontrolled medical illnesses of the cardiovascular, respiratory, endocrine, renal, gastrointestinal, genitourinary or immune system; history of myocardial infarction; history of idiopathic ventricular tachycardia or ventricular fibrillation in the past 12 months or history of ventricular tachycardia or ventricular fibrillation (VT/VF) associated with VT/VF risk factors (e.g., QT prolongation and cardiomyopathy); active cardiac arrhythmias (Active atrial fibrillation is not allowed, but resolved atrial fibrillation is allowed.); active obstructive or restrictive pulmonary disease; or active autoimmune diseases such as rheumatoid arthritis Patients will not be seen for screening appointments or enrolled on the protocol if they have been hospitalized within the 7 days prior to the screening appointment or the date of protocol enrollment Any form of primary immunodeficiency (such as Severe Combined Immunodeficiency Disease) , unless the immunodeficiency has been cured by allogeneic stem cell transplant
