A gram-negative bacteria designated DF-3 was cultured on multiple occasions from stool samples of a patient with common variable hypogammaglobulinemia and chronic diarrhea. Antibiotic therapy resulted in elimination of the organism and resolution of the patient's symptoms. DF-3 has not been linked previously to human disease; because of its fastidious growth characteristics and unique isolation requirements, it may be a rarely identified cause of diarrhea and other gastrointestinal symptoms in immunocompromised patients.

The Swiss Group for Clinical Cancer Research (SAKK) and the Nordic Lymphoma Group (NLG) conducted the SAKK 35/10 randomized phase-2 trial (NCT0137605) to compare rituximab (R) alone versus R plus lenalidomide (L) as initial treatment for follicular lymphoma (FL). Patients with grade 1-3a FL, requiring systemic therapy, were randomized to either R (n=77; 375 mg/m2 IV x 1, weeks 1-4) or RL (n=77; R on the same schedule and L at 15 mg daily continuously). Responders (evaluated at 10 weeks) repeated R during weeks 12-15 with or without L (for a total of 18 weeks).

Blood

January 2025

Department I of Internal Medicine and German CLL Study Group; Center for Integrated Oncology Aachen Bonn Cologne Duesseldorf (CIO ABCD); University of Cologne, Faculty of Medicine and University Hos, Cologne, Germany.

The phase 2 CLL2-BZAG trial tested a measurable residual disease (MRD)-guided combination treatment of zanubrutinib, venetoclax and obinutuzumab after an optional bendamustine debulking in patients with relapsed/refractory CLL. In total, 42 patients were enrolled and two patients with ≤2 induction cycles were excluded from the analysis population per protocol. Patients had a median of one prior therapy (range 1-5), 18 patients (45%) had already received a BTK inhibitor (BTKi), seven patients (17.

Health Care Delivery and Financial Considerations in Amyotrophic Lateral Sclerosis Clinics: A Survey of Clinic Directors.

Neurology

February 2025

From the Temple University College of Public Health (I.L.H.); Thomas Jefferson University (G.G.); and Department of Neurology (T.D.H.-P.), Lewis Katz School of Medicine at Temple University, Philadelphia, PA.

Background And Objectives: Clinical care for people living with amyotrophic lateral sclerosis (PLWALS) is directed at slowing disease progression and symptom management. The American Academy of Neurology recommends a multidisciplinary approach to providing ALS health care because observational studies show that multidisciplinary clinics (MDCs) extend survival and improve quality of life. However, providing multidisciplinary care is a challenging financial proposition.

Purpose: Prior noncontemporary studies showed that oral cyclophosphamide is an active treatment of metastatic castration-resistant prostate cancer (mCRPC). However, cyclophosphamide is currently underutilized in routine clinical practice given the lack of survival benefit and the emergence of more effective treatments.

Methods: We retrospectively reviewed our institutional database to identify patients with mCRPC treated with cyclophosphamide.
