Ibrutinib is a Bruton tyrosine kinase (BTK) inhibitor used in B-cell lymphoproliferative disorders. Patients with genetic BTK deficiency are susceptible to recurrent and severe Campylobacter infections. We report 4 patients treated with ibrutinib who developed chronic or extra-digestive campylobacteriosis resembling ibrutinib-related adverse events including diarrhea (n = 4), panniculitis (n = 2), and arthritis (n = 1). Microbiol. explorations identified Campylobacter jejuni (n = 3) or Campylobacter coli (n = 1). All the patients completely recovered after a short course of oral antibiotic therapy. In patients treated with ibrutinib presenting with chronic diarrhea, dermatol., or rheumatol. manifestations, campylobacteriosis should be ruled out before attributing the symptoms to ibrutinib and discuss its discontinuation.

A concern has been raised that the persistent COVID-19 infection in an immunocompromised host can be the source of the SARS-CoV-2 variants. This is the case of a 61-yr-old man in complete remission of a follicular lymphoma after six cycles of rituximab and bendamustine with addnl. two cycles of rituximab completed eight months prior to the episode of COVID-19 pneumonia. The patients respiratory failure was long-lasting, and required mech. ventilation until day 75. Acquired immunity tested neg. throughout the observational period. The viral RNA was detectable until day 100 while the infectious virus was isolated until day 79. Seven haplotypes were identified and the non-synonymous mutations accumulated in the spike gene which included E484Q and S494P. In the management of COVID-19 cases with suppressed immune statuses, initial evaluation of existing immunity and monitoring for infectiousness throughout the clin. course including the convalescent stage may be necessary.

Selinexor is a first-in-class, oral therapy that selectively inhibits nuclear export. The drug is active with an overall response rate (ORR) of approx. 30% in relapsed/refractory (r/r) non-Hodgkin lymphoma (NHL). Long-term patient follow-up has not been reported. Thirty-one NHL patients were treated between July 2012 and July 2018; 22 were evaluated for response. ORR was 32% (7/22). Two patients achieved complete remission (CR) and were alive and lymphoma-free at the end of follow-up. Fifteen patients (68%) progressed during treatment, most of them died within 3-10 mo. The most common grade 3/4 adverse events were gastrointestinal and hematol. Median follow up was 50 mo. Overall survival for the entire cohort was 16%. Selinexor monotherapy for r/r NHL is an active therapy with the potential for long-term disease control. It may serve as a ‘bridge’ to subsequent therapy. Addnl. studies are needed to identify predictive biomarkers and to evaluate combination approaches.

Breast extranodal marginal zone lymphoma (EMZL) is a rare malignancy. We performed the largest published to date single-center retrospective anal. of 13 patients with breast EMZL focusing on clin. characteristics and treatment-related outcomes. The rarity of this disease at our center was concordant with the prevalence reported in the literature, with breast EMZL comprising 2% of 654 MZL cases. Most patients presented with stage I-II disease however four (30.8%) patients had stage IV disease mostly due to occult bone marrow (BM) involvement. Interestingly, EMZL was frequently non-FDG avid (66.7%) on staging PET/CT. With a median follow-up of 3.1 years (range 5 mo to 10.2 years), the 3-yr progression free survival was 68.7% (95%CI 30.2%-88.9%) and overall survival 80.2% (95%CI 40.3%-94.8%). No patient experienced higher-grade transformation. Herein we show that localized breast EMZL can be effectively treated with radiation therapy providing long term disease control.

BR (bendamustine plus rituximab) versus R-CHOP for patients with indolent B-cell lymphomas: a systematic review and Meta-analysis was written by Ou, Wenxin;Jiang, Tiantian;Tang, Xiaoqiong. And the article was included in Journal of Chemotherapy (Abingdon, United Kingdom).HPLC of Formula: 16506-27-7 The following contents are mentioned in the article:

A review. Bendamustine plus rituximab (BR) and rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP) have been shown to be effective in the treatment of indolent B-cell lymphomas (iBCL). The survival outcomes and adverse events of BR and R-CHOP are still controversial, thus we did a systematic review and meta-anal. to assess them. We searched articles in Pubmed, Cochrane, Embase and Web of Science comparing BR to R-CHOP in patients with iBCL. A total of 3141 patients were included. The results of our meta-anal. revealed that BR has the potential of improving PFS (HR = 0.67, p = 0.03). No apparent benefit of BR was noted in patients with iBCL for OS (HR = 1.18, p = 0.04). Compared with R-CHOP, we found that BR regimen had the potential of prolonging PFS, minor toxicity, a better quality of life, and better cost-effectiveness. These results supported BR as a preferred first-line treatment option for patients (especially for elders) with iBCL.

The primary endpoint was overall response rate (ORR). Autologous stem cell transplantation-ineligible rrDLBCL patients with �2 prior chemotherapy regimens received R 375 mg/m2 IV on day 1 and B 120 mg/m2/day IV on days 2 and 3 every 21 days up to 6 cycles. Thirty-eight patients with a median age of 74 years (range, 43-86) received BR. The ORR and complete response rates were 76.3% and 47.4%, resp. With a median follow-up of 19.5 mo including long-term follow-up, median progression-free survival was 11.9 mo. Median OS was 29.2 mo. Discontinuation of treatment due to Gr3-5 TEAE was observed among 13 of 38 patients (34.2%). One patient with cytomegalovirus enterocolitis died during follow-up.

The water electrolysis for production of hydrogen in the Bronsted acid ionic liquid [HMIm]HSO₄ aqueous solutions was investigated using glassy carbon (GC), platinum (Pt), and gold (Au) electrodes, resp. It was found that the catalytic activity of the electrodes in the acid ionic liquid electrolytes ranked in sequence as Pt > Au >> GC. The optimal concentration of [HMIm]HSO₄ in aqueous solutions was 30% (V/V), and the catalytic c.d. on Pt electrode for hydrogen evolution reaction (HER) at -0.5 V (Ag QRE) reached 110.52 mA/cm². This was 15 and 650-fold larger than the current on the Au and GC electrode, resp. The Arrhenius activation energy of the Pt electrode in the electrolyte solution was 5.68 kJ/mol. The high catalytic activity of the electrode was attributed to the [HMIm]HSO₄ that would release protons enabling H₂O mols. ionization, and facilitating the capture of electrons from the electrode.

And the article was included in Shiyou Huagong Gaodeng Xuexiao Xuebao in 2013.HPLC of Formula: 478935-29-4 The following contents are mentioned in the article:

A series of N-methylimidazolium hydrosulfate type of ionic liquids (ILs) bearing different length of alkyl chains were synthesized. The ionic liquids were applied both as extracting reagent and catalyst for the model or true oil desulfurization using hydrogen peroxide (35%) as the oxidant. The desulfurization conditions were optimized by varying extraction time, the ratio of ILs/oil, temperature and so on. Under the optimal conditions, the ILs were also used for the desulfurization of FCC gasoline and diesel. The results show that, [C₃mim]HSO₄ has the highest desulfurization rate. The best desulfurization rate was obtained after 1.5 h under the condition of V ([C₃mim]HSO₄)/V (H₂O₂)/V (oil) = 1 : 1 : 30 at 60°C for the model oil (88.38%) and diesel (80%).

The condensation of glycerol, a platform chem. from renewable materials, with benzaldehyde to generate cyclic acetals was investigated using acidic ionic liquid as catalyst. Evidence was presented that the product mixture of 4-hydroxymethyl-2-phenyl-1,3-dioxolane and 5-hydroxyl-2-phenyl-1,3-dioxane, with cis and trans two stereo-isomers for each one identified by ¹H NMR were obtained. Further modification of reaction conditions promoted by N-butyl-pyridinium bisulfate ([BPy]HSO₄) led to the totally cyclic acetals with 99.8% yield at room temperature A micro water-removal reactor constituted by ionic liquids was proposed, which favorably shifted the condensation equilibrium to the product side by transferring the produced water out of the organic phase in time, so that the water-carrying agent or reactive distillation was avoided.
