RESUMEN

Hydrolyzed collagen (HC) derived from salmon (Oncorhynchus nerka) skin possesses properties that can nourish the skin, and it is one of the active ingredients used in cosmeceutical products for moisturizing the facial skin. However, HC solution gives off a fishy odor and it is gray in color that makes the product unacceptable for cosmetic purposes. This study aimed to use liposome-encapsulated hydrolyzed salmon collagen to improve its physical appearance, skin permeation, and eliminate the fishy odor. Two percent of HC and vitamin B3 (VitB3) were used as active ingredients to incorporate into liposomes. Phosphatidylcholine, cholesterol, and Tween 80 at a suitable weight ratio of 8 : 2 : 1 produced nano-sized vesicles (170.6 ± 0.70 nm) with the highest percentage of entrapment efficiency (95.72 ± 2.00%) of VitB3 and (49.63 ± 1.74%) of HC. Skin permeation and odor detection of the HC-VitB3 liposome were studied using Franz's diffusion cell and gas chromatography, respectively, and compared with HC-VitB3 solution. Subsequently, facial serums were formulated using HC-VitB3 liposomes and HC-VitB3 solutions, and a product satisfaction test was conducted with 100 volunteers to determine their preferred product. The results of the studies of HC-VitB3 liposome serum showed improved formulation appearance, enhanced skin permeation, and better odor elimination compared to the HC-VitB3 serum. Furthermore, seventy-three volunteers in the product satisfaction test preferred and selected the liposomal serum for its superior scent. From all the experimental results, it could be seen that liposomes can help increase skin penetration, and undesirable odors and colors can be masked by the appropriate lipid bilayer structure of liposomes.

RESUMEN

This multicenter, phase II study of the Australasian Lymphoma and Leukemia Group and the Asian Myeloma Network investigated fixed-duration (18-month) treatment with carfilzomib (K), thalidomide (T), and dexamethasone (d) (KTd) in patients with relapsed and/or refractory multiple myeloma who had received one to three prior lines of therapy. Patients received induction with up to 12 28-day cycles of carfilzomib (20 mg/m2 intravenously in cycle 1 on days 1 and 2, then 56 mg/m2 [36 mg/m2 for patients ≥75 years] from day 8 onwards), thalidomide 100 mg orally in the evening and weekly dexamethasone 40 mg (20 mg for patients ≥75 years). During maintenance, thalidomide was omitted, while carfilzomib was continued on days 1, 2, 15, and 16 with fortnightly dexamethasone. The primary endpoint was progression-free survival. Secondary endpoints were overall response rate, overall survival, duration of response, safety, and tolerability. Ninety-three patients (median age 66.3 years [range, 41.9-84.5]) were enrolled and followed up for a median of 26.4 months (range, 1.6-54.6). The median progression-free survival was 22.3 months (95% confidence interval: 15.7-25.6) and the 2-year progression-free survival was 46.3% (95% confidence interval: 35.1-52.8). The median overall survival was not reached and the 2-year overall survival was 73.8% (95% confidence interval: 62.9-81.9). The overall response rate was 88% (73% had a very good partial response or better). There was no difference in the depth of response, progression-free survival or overall survival comparing Asian and non-Asian cohorts (P=0.61). The safety profile of KTd was consistent with that of each individual drug. KTd is well tolerated and effective in patients with relapsed and/or refractory multiple myeloma irrespective of Asian or non-Asian ethnicity and provides an alternative treatment option, particularly in circumstances in which the use of carfilzomib, lenalidomide, and dexamethasone (KRd) is limited by access, cost, or renal impairment.

RESUMEN

BACKGROUND: There is no currently available standard of care for triple-class exposed, relapsed refractory myeloma (RRMM) patients in Australia. CARTITUDE-1 (CART-1) was a single-arm, phase 1b/2 study of 97 triple-class exposed RRMM patients, who received BCMA-CAR-T cell therapy with ciltacabtagene autocel. Overall response rate (ORR) was 98%. Median progression free survival (PFS) and overall survival (OS) had not been reached at a median follow-up of 28 months. METHODS: We performed a retrospective analysis on a cohort of CART-1 comparable RRMM patients participating in the Australian and New Zealand Myeloma and Related Diseases Registry (MRDR), to compare outcomes in triple-class exposed MM patients treated with currently available therapies, in a real-world context. The CE-MRDR cohort (n = 28) fulfilled CARTITUDE-1 eligibility (CE) criteria: ≥3 lines of therapy (LOT) including an immunomodulatory agent, proteasome inhibitor and CD38-directed monoclonal antibody (CD38mAb) and Eastern Cooperative Oncology Group Performance Status (ECOG PS) score of 0-2 at diagnosis. The modified-CE-MRDR (n = 132) received ≥3 LOT but may not have received a CD38mAb with an ECOG PS score of 3 (0-3). RESULTS: Responses to the first subsequent therapy after eligibility were poor - ORR was 23% and 0% with progressive disease (PD) reported in 61% and 36%, CE-MRDR and m-CE-MRDR respectively. Responses to the second subsequent therapy after eligibility were worse, ORR 0% and 31%, CE-MRDR and m-CE-MRDR respectively, with high rates of PD, particularly in CE-MRDR. Median OS was 5.4 versus 9.5 months, CE-MRDR versus m-CE-MRDR. CONCLUSIONS: This retrospective analysis confirms uniformly poor outcomes for Australian RRMM patients. There remains a critical need for greater accessibility to novel treatments, such as CAR-T, outside clinical trials.

RESUMEN

Hepatosplenic T cell lymphoma is a rare subtype of non-Hodgkin lymphoma affecting younger adult men and immunocompromised individuals. The neoplastic cells typically express surface CD3, CD2 and CD7. We report a rare case of hepatosplenic T cell lymphoma with an aberrant loss of sCD3 at diagnosis.This case report is written based on reviewing electronic health data, liver biopsy histology, bone marrow biopsy and conventional cytogenic analysis. Literature search for case reports were conducted on PubMed database and Google Scholar.Our case presents a de novo hepatosplenic T cell lymphoma with loss of surface CD3 expression on immunohistochemistry and flow cytometry. The unusual immunophenotype has been reported in three previous cases, and likely contributed to a delay in diagnosis of our patient.Hepatosplenic T cell lymphoma with loss of surface CD3 expression is a rare histological presentation which warrants further research into its prognostic significance. This unusual presentation can cause delay in diagnosis.

RESUMEN

New Zealand is a small country of two islands and 4 million people, of which 1 million reside in the South Island. Canterbury Health Laboratories provides laboratory services to the whole of South Island and lower parts of North Island. There are 155 Von Willebrand disease (VWD) patients in our South Island database, of which 17 have type 2 and 3 have type 3 VWD. A brief overview of diagnostic services for VWD being followed in our region is detailed in this article. We strive continually to advance the repertoire of diagnostic tests. We also present an analysis of our experience with a flow-based functional Von Willebrand factor assay. The VWD patients are managed by hemostasis team members, who also provide screening and educational input to affected families. The Haemophilia Foundation of New Zealand is an active patient support group providing education and support both directed individually and in the group setting, through residential educational camps.
