RESUMO

INTRODUCTION: The treatment of relapsed or refractory Hodgkin lymphoma is still a major therapeutic challenge. The use of brentuximab vedotin, an anti-CD30 antibody-drug conjugate, represents a promising approach for these patients, however clinical outcomes have not yet been evaluated in Hungary. AIM: Our aim was to assess the efficacy, safety and outcome of brentuximab vedotin treatment in Hungarian Hodgkin lymphoma patients. METHOD: In this retrospective case note review we enrolled patients at 6 clinical sites countrywide who were diagnosed with Hodgkin lymphoma and received brentuximab vedotin between 1 January 2013 and 31 December 2016. RESULTS: A total of 86 patients were treated with brentuximab vedotin during the examined period. Before therapy initiation 66% of our patients had advanced-stage disease. Overall response rate to brentuximab vedotin, administered before autologous hematopoietic stem cell transplantation (n = 54) was 66.6%, complete remission rate was 42.6%. Thirty patients received brentuximab vedotin after AHSCT, 46.67% responded to treatment, 30% achieved complete remission. Thirty-six patients received the drug as a single-agent therapy, 50 patients were given brentuximab vedotin in combination, 39 of them with bendamustin. Toxicity was observed only in 13.95% of our patients, most common symptom was skin rash. Based on our analysis the estimated 5-year overall survival rate was 78.7%, the estimated progression free survival rate was 23.59 months (95% CI: 19.50-27.68). CONCLUSION: Brentuximab vedotin carries a substantial improvement in the treatment of relapsed or refractory Hodgkin lymphoma. Our results underline prior observations published in the literature. The use of brentuximab vedotin in combination can be beneficial, however further investigation is needed on the subject. Orv Hetil. 2017; 158(41): 1630-1634.

RESUMO

Four previously healthy adult domestic shorthair cats (2 male, 2 female) from one household developed acute vomiting and ataxia less than 12 hours after consuming a commercial canned cat food. Blood work abnormalities included mild hyperglycemia with increased alanine aminotransferase (n = 1) and decreased blood urea nitrogen (n = 2). The veterinarian conducted whole blood ethylene glycol (EG) tests, which were positive for all cats. There were no known EG exposures. All cats were treated for suspected EG toxicosis and fully recovered after 48 hours. Separately from the cats' case, the same food was voluntarily recalled by the manufacturer 5 days later due to a higher-than-formulated amount of choline chloride added to the food. The 4 cats' canned cat food was tested for choline, choline chloride, EG, diethylene glycol, and propylene glycol to look for causes of the positive whole blood EG test. The cat food contained an average of 165,300 ppm (165,300 mg/kg) choline and 221,600 ppm (221,600 mg/kg) choline chloride on a dry matter basis, which is at least 65 times the recommended choline amount for adult cats. No glycols were detected. This case documents suspected choline toxicosis in cats after consuming a commercial canned cat food with a higher-than-formulated amount of choline chloride, and it suggests that choline toxicosis may cause a positive result on some EG whole blood tests. Choline toxicosis could be a possible differential diagnosis when a cat has a positive EG test and no known exposure to antifreeze.

RESUMO

Dietary exogenous thyrotoxicosis is infrequently observed in pet food. A retrospective evaluation of pet food investigations (PFI) was conducted for 17 dogs, including review of medical records, dietary and environmental exposure interviews, food testing, and regulatory action. Five PFIs occurring between 2016 and 2018 involved 7 food products including 2 food types, jerky treats or canned food, made from beef or bison. The dogs' serum thyroid hormone concentrations were evaluated before and after diet change. The foods were tested for active thyroid hormones and hormone precursors using high performance liquid chromatography with inductively coupled plasma mass spectrometry detection. The foods were also examined microscopically. Serum thyroid hormone concentrations of thyroxine (T4) varied depending on the food type consumed. Dogs that consumed dried jerky containing greater T4 concentrations often had increased serum T4 concentrations, whereas dogs that consumed canned products containing greater and 3,4,5- and 3,5,3'-triiodothyronine (T3) concentrations often had decreased serum T4 concentrations. After the diets were changed, serum T4 and T3 concentrations normalized at 1 month. Seven foods containing beef or bison had iodine concentrations greater than 11 mg/kg, and iodine speciation identified variable concentrations of iodide, T4, T3, monoiodotyrosine (MIT), and di-iodotyrosine (DIT). Thyroid gland was found in microscopic sections from one finished food and one ingredient, gullet. FDA performed Health Hazard Evaluations to categorize the exposure risk, and 5 foods were recalled for which the product packaging had not been discarded. Dietary exogenous thyrotoxicosis should be considered in dogs exhibiting clinical signs compatible with hyperthyroidism, especially if consuming beef-based food. A thyroid panel that includes serum iodine, coupled with a thorough feeding history can aid in diagnosis. Thyrotoxicosis is typically reversible after removing the contaminated food from the diet.

RESUMO

Daratumumab is a human anti-CD38 monoclonal antibody used in the treatment of refractory and relapsed multiple myeloma. We investigated the efficacy and safety of daratumumab therapy in a real-world setting. Ninety-nine Hungarian patients were included; 48 received monotherapy, while lenalidomide and bortezomib combinations were administered in 29 and 19 cases, respectively. Overall response rate was assessable in 88 patients, with 12 complete, 10 very good partial, 34 partial, and seven minor responses. At a median duration of follow-up of 18.6 months, median progression-free survival (PFS) among all patients was 17.0 months. These values were inferior in the bortezomib combination and monotherapy groups. Patients with early-stage disease (ISS1) had better survival results than those with stage 2 or 3 myeloma (p = 0.009). Heavily pretreated patients had inferior PFS compared to those with 1-3 therapies (p = 0.035). Patients with impaired renal function had PFS results comparable with those having no kidney involvement. There were 10 fatal infections, and the most frequent adverse events were mild infusion-associated reactions and hematologic toxicities. Our results confirm that daratumumab is an effective treatment option for relapsed/refractory MM with an acceptable safety profile in patients with normal and impaired renal function.

RESUMO

Multiple myeloma (MM) is a heterogeneous disease group regarding prognosis, clinical course, and response to therapeutic interventions. Numerous prognostic factors have been identified however there was no consensus about the best prognostic indicators or the proper staging systems. In a previous study the A/M ratio containing albumin (A) and monoclonal component (M) emerged as reliable predictor of survival duration in patients treated with conventional chemotherapy. In the current retrospective study authors evaluated the prognostic role of this fraction in the era of novel agents. They assessed the A/M ratio prior treatment in 56 newly diagnosed MM patients from the aspect of the survival time. According to the results the A/M being <1 at the diagnosis indicated significantly poorer prognosis both at the 2 years (p = 0,01) and at the 5 years (p = 0,07) survival endpoints. These results proved that A/M ratio remained valuable marker for predicting prognosis in patients treated with proteosome inhibitor and antiangiogenic therapy as well. Authors recommend therefore applying this A/M ratio in further studies for the better pre-treatment stratification.
