Pre-existing central nervous system ( CNS) involvement may influence referral for autologous haematopoietic cell transplantation ( AHCT) for patients with non-Hodgkin lymphoma ( NHL). The outcomes of 151 adult patients with NHL with prior secondary CNS involvement ( CNS+) receiving an AHCT were compared to 4688 patients without prior CNS lymphoma ( CNS−). There were significant baseline differences between the cohorts. CNS+ patients were more likely to be younger, have lower performance scores, higher age-adjusted international prognostic index scores, more advanced disease stage at diagnosis, more aggressive histology, more sites of extranodal disease, and a shorter interval between diagnosis and AHCT. However, no statistically significant differences were identified between the two groups by analysis of progression-free survival ( PFS) and overall survival ( OS) at 5 years. A matched pair comparison of the CNS+ group with a subset of CNS− patients matched on propensity score also showed no differences in outcomes. Patients with active CNS lymphoma at the time of AHCT ( n = 55) had a higher relapse rate and diminished PFS and OS compared with patients whose CNS lymphoma was in remission ( n = 96) at the time of AHCT. CNS+ patients can achieve excellent long-term outcomes with AHCT. Active CNS lymphoma at transplant confers a worse prognosis. [ABSTRACT FROM AUTHOR]

The neuroprotective effects of granulocyte colony-stimulating factor (G-CSF) were reported in several neurological disease models, including Parkinson’s disease (PD). In the present study, we investigated the therapeutic effect of G-CSF after the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of PD was established. G-CSF was subcutaneously administered into C57BL/6 mice that had undergone systemic MPTP injections. We found that G-CSF treatment markedly increased the number of dopaminergic neurons in the substantia nigra pars compacta (SNpc) of the G-CSF-treated group. Consistent with this finding, we found a significant increase in dopamine release under high K+ stimulation in the striatum of the G-CSF-treated animals compared to the MPTP-exposed mice. Finally, we observed a persistent recovery of locomotor function in the G-CSF-treated animals. These results suggest the potential therapeutic value of G-CSF in treating PD. However, our bromodeoxyuridine labeling experiment failed to identify any newly generated dopaminergic neurons in SNpc. This might indicate an indirect effect of G-CSF on cell proliferation. The underlying mechanism of G-CSF is under further investigation. [ABSTRACT FROM AUTHOR]

Interstitial Cystitis or Bladder Pain Syndrome (IC/BPS) is a heterogeneous condition characterized by elevated levels of inflammatory cytokines, IL-1β, IL-6, IL-8, IL-10, TNF-α, and is associated with debilitating symptoms of pelvic pain and frequent urination. A standard of care for IC/BPS has not been established, and most patients must undergo a series of different treatment options, with potential for severe adverse events. Here, we report a patient with a 26-year history of IC/BPS following treatment with multiple therapies, including low doses of etodolac, amitriptyline and gabapentin, which she was unable to tolerate because of adverse effects, including headaches, blurred vision and cognitive impairment. The patient achieved a complete clinical remission with minimal adverse events after 16 cycles of N-acetylcysteine (NAC) intravenous (IV) infusions over a period of 5 months, and pro-inflammatory cytokine levels were reduced when compared to measurements taken at presentation. Personalized low dose NAC IV infusion therapy represents an effective, safe, anti-inflammatory therapy administered in the outpatient setting for IC/BPS, and warrants further investigation.

Chronic lymphocytic leukemia (CLL) accounts for 10% of hematologic malignancies. CLL is a malignancy of CD5+ B cells and it is characterized by the accumulation of small, mature-appearing neoplastic lymphocytes in the blood, bone marrow, and secondary lymphoid tissues. In the present case, a middle-aged female patient with poor prognosis unmutated IGHV CLL achieved cytogenetic and molecular remission with minimal adverse events following six cycles of low dose recombinant human IL-2 (rIL-2) in combination with low dose targeted venetoclax. Personalized low dose rIL-2 in combination with either lenalidomide or venetoclax mediates natural killer stimulation and is an effective non-toxic immunotherapy administered in the outpatient setting for poor prognosis CLL.
