RESUMEN

OBJECTIVE: Albumins are protein molecules that account for 50% of total plasma protein. They are imperative in maintaining intravascular colloidal oncotic pressure, act as key scavenger molecules for oxygen free radicals, and perform a major role in transporting numerous substances and in wound healing. Hypoalbuminemia has been reported as the consequence of decreased intake, increased loss, decreased production, and redistribution. While anecdotal evidence of tyrosine kinase inhibitors causing hypoalbuminemia in canine patients exists, to the author's knowledge there is no formal report to this effect to date. This case report aims to bridge the gap between anecdotal evidence and literature. ANIMAL: 3-year-old neutered male hound-mix canine. CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES: The patient was presented for recurrent otitis externa refractory to treatments with orbifloxacin/mometasone/posaconazole otic suspension, miconazole/polymyxin B/prednisolone otic suspension, ketoconazole/TrizEDTA, and gentamicin/mometasone/clotrimazole, which prompted consideration of oral antifungals. Baseline blood work prior to initiation of fluconazole showed elevated alkaline phosphatase. Treatment was initiated with fluconazole, and blood work was rechecked and revealed hypoalbuminemia. Multiple diagnostic tests failed to reveal a cause of hypoalbuminemia. TREATMENT AND OUTCOME: Discontinuation of oclacitinib that the patient was being administered resulted in normalization of serum albumin. CLINICAL RELEVANCE: It is unclear whether hypoalbuminemia associated with oclacitinib administration is associated with worse outcomes for pathologies in canine patients; however, this seems to be the case in humans according to some reports. This report aims to take a step in the direction of this knowledge.

RESUMEN

Voriconazole (VRC) displays highly variable pharmacokinetics impacting treatment efficacy and safety. To provide evidence for optimizing VRC therapy regimens, the authors set out to determine the factors impacting VRC steady-state trough concentration (Cmin) in patients with various albumin (Alb) level. A total of 275 blood samples of 120 patients and their clinical characteristics and genotypes of CYP2C19, CYP3A4, CYP3A5, CYP2C9, FMO3, ABCB1, POR, NR1I2 and NR1I3 were included in this study. Results of multivariate linear regression analysis demonstrated that C-reactive protein (CRP) and total bilirubin (T-Bil) were predictors of the VRC Cmin adjusted for dose in patients with hypoalbuminemia (Alb < 35 g/L) (R2 = 0.16, P < 0.001). Additionally, in patients with normal albumin level (Alb ≥ 35 g/L), it resulted in a significant model containing factors of the poor metabolizer (PM) CYP2C19 genotype and CRP level (R2 = 0.26, P < 0.001). Therefore, CRP and T-Bil levels ought to receive greater consideration than genetic factors in patients with hypoalbuminemia.

RESUMEN

INTRODUCTION: There are conflicting findings on the link between liver fibrosis and cumulative methotrexate dosages. We aimed to determine the frequency of liver fibrosis in rheumatoid arthritis patients treated with methotrexate and to identify its associated factors. METHODS: We conducted a cross-sectional study over 9 months (April-December 2021), including rheumatoid arthritis patients treated with methotrexate. Demographic and clinical data were collected. Liver stiffness was assessed by FibroScan. Fibrosis and significant liver fibrosis were defined as liver stiffness higher than 6 and 7.2 kPa, respectively. Liver tests, albuminemia, lipid profile, and blood glycemia were measured. Metabolic syndrome was also evaluated. Statistical analyses were performed using SPSS. RESULTS: We included 21 men and 47 women. The mean age was 51.60 ± 1.82 years. The mean disease duration was 8.29 ± 6.48 years. The mean weekly intake of methotrexate was 13.76 ± 3.91 mg. The mean methotrexate duration was 4.67 ± 4.24 years. The mean cumulative dose was 3508.87 ± 3390.48 mg. Hypoalbuminemia and metabolic syndrome were found in 34% and 25% of cases. We noted increased alkaline phosphatase levels in four cases. The mean liver stiffness was 4.50 ± 1.53 kPa. Nine patients had liver fibrosis, and four had significant fibrosis. Associated factors with liver fibrosis were as follows: age ≥ 60 years (OR:22.703; 95%CI [1.238-416.487]; p = 0.035), cumulated dose of methotrexate ≥ 3 g (OR: 76.501; 95%CI [2.383-2456.070]; p = 0.014), metabolic syndrome (OR: 42.743; 95%CI [1.728-1057.273]; p = 0.022), elevated alkaline phosphatase levels (OR: 28.252; 95%CI [1.306-611.007]; p = 0.033), and hypoalbuminemia (OR: 59.302; 95%CI [2.361-1489.718]; p = 0.013). CONCLUSION: Cumulating more than 3 g of methotrexate was associated with liver fibrosis in rheumatoid arthritis patients. Having a metabolic syndrome, higher age, hypoalbuminemia, and elevated alkaline phosphatase levels were also likely to be independently associated with liver fibrosis. Key points • Rheumatoid arthritis patients require monitoring hepatic fibrosis when the cumulated dose of methotrexate is above 3 g. • Metabolic syndrome is a risk factor for liver fibrosis, suggesting that its management is necessary to prevent this complication. • Hypoalbuminemia and elevated alkaline phosphatase levels (twice the upper limit) in rheumatoid arthritis patients treated with methotrexate were associated with liver fibrosis.

RESUMEN

INTRODUCTION: A recent finding of a deep venous thrombosis during spaceflight has prompted the need to clarify mechanisms and risks of venous thromboembolism (VTE). In turn, mitigation countermeasures, diagnostic modalities, and treatment options must be explored. The objective of this review was to synthesize current evidence on VTE in spaceflight.METHODS: A literature review was performed from inception to April 2023 pertaining to VTE in the context of spaceflight or ground-based analogs with human participants. PubMed was searched for papers written in English using the terms "spaceflight" or "weightlessness" and "thrombotic" or "embolism" or "thromboembolism" in "venous" or "veins". Papers using cellular or animal models were excluded.RESULTS: There were 63 papers captured; 7 original scientific studies, 3 narrative reviews, 2 systematic reviews, and 3 commentaries discussed VTE in spaceflight. Reference lists were screened. Important themes included: altered venous hemodynamics, increased fibrinogen and coagulation markers, hypoalbuminemia, and immune dysfunction. Additional risk factors may be seen in women, such as the use of oral contraceptives.DISCUSSION: Venous stasis and decreased shear stress secondary to fluid shifts may induce inflammatory changes in the venous system, resulting in endothelial damage and upregulation of the coagulation cascade. Additionally, women in space are subject to physiological factors increasing their VTE risk, such as the use of oral contraceptives, inducing increased blood viscosity and hypoalbuminemia. Efforts should also be placed in optimizing sensitivity and specificity of imaging markers, payload, and training ability, notably the use of vector flow imaging, and improving point-of-testing biomarkers, such as albumin and p-selectin.Levasseur S, Purvis N, Trozzo S, Chung SH, Ades M, Drudi LM.

RESUMEN

BACKGROUND: In preclinical pancreatic ductal adenocarcinoma (PDAC) models, inhibition of hepatocyte growth factor (HGF) signaling using ficlatuzumab, a recombinant humanized anti-HGF antibody, and gemcitabine reduced tumor burden. METHODS: Patients with previously untreated metastatic PDAC enrolled in a phase Ib dose escalation study with 3 + 3 design of 2 dose cohorts of ficlatuzumab 10 and 20 mg/kg administered intravenously every other week with gemcitabine 1000 mg/m2 and albumin-bound paclitaxel 125 mg/m2 given 3 weeks on and 1 week off. This was followed by an expansion phase at the maximally tolerated dose of the combination. RESULTS: Twenty-six patients (sex, 12 male:14 female; median age, 68 years [range, 49-83 years]) were enrolled, 22 patients were evaluable. No dose-limiting toxicities were identified (N = 7 pts) and ficlatuzumab at 20 mg/kg was chosen as the maximum tolerated dose. Among the 21 patients treated at the MTD, best response by RECISTv1.1: 6 (29%) partial response, 12 (57%) stable disease, 1 (5%) progressive disease, and 2 (9%) not evaluable. Median progression-free survival and overall survival times were 11.0 months (95% CI, 7.6-11.4 months) and 16.2 months (95% CI, 9.1 months to not reached), respectively. Toxicities attributed to ficlatuzumab included hypoalbuminemia (grade 3, 16%; any grade, 52%) and edema (grade 3, 8%; any grade, 48%). Immunohistochemistry for c-Met pathway activation demonstrated higher tumor cell p-Met levels in patients who experienced response to therapy. CONCLUSION: In this phase Ib trial, ficlatuzumab, gemcitabine, and albumin-bound paclitaxel were associated with durable treatment responses and increased rates of hypoalbuminemia and edema.

RESUMEN

CONTEXT: Patients with membranous nephropathy (MN) are recognized as individuals with high risk of thrombosis. However, prophylactic anticoagulant therapy in this population is still a controversial topic for a lack of high-quality evidence. Subject of Review: The Kidney Disease: Improving Global Outcomes (KDIGO) 2021 Clinical Practice Guideline for the Management of Glomerular Diseases was published in Kidney International in October 2021, and it was updated on the topic of prophylactic anticoagulant therapy in patients with MN. Differing from the previous main concern about the risk of venous thromboembolism (VTE) in MN, it paid attention to the risk of arterial thromboembolism (ATE) as well. Additionally, the risk of ATE was considered to be associated with hypoalbuminemia. A tool for evaluating the risk of bleeding in patients with MN was proposed in the KDIGO 2021 guideline, and individuals with low risk of bleeding as well as high risk of VTE were suggested to use warfarin or low-molecular-weight heparin (LMWH) combined with aspirin, as an alternative regimen for warfarin. Second Opinion: Our analysis shows that no consensuses have been reached on whether the prevention of ATE is necessary for patients with MN or whether the risk of ATE is associated with hypoalbuminemia. The proposed tool is not the only choice of tools for bleeding assessment, and the HAS-BLED risk score might be a better choice from the perspective of general applicability and availability. Furthermore, in our opinion, the suggestion for prophylaxis regimen of LMWH combined with aspirin showed a lack of consideration and might be inappropriate to some degree. In summary, there are still many controversies in the field of prophylactic anticoagulation for MN; as a consequence, more high-quality studies are required to provide guidance.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: The aim of this study was to evaluate the pharmacokinetics of paclitaxel in cancer patients with hypoalbuminemia following paclitaxel-containing chemotherapy and to provide a reference for the prevention of adverse events (AEs) after paclitaxel administration. METHODS: Peripheral blood was collected from cancer patients treated with paclitaxel. The plasma concentration of paclitaxel was determined by ultra-high performance liquid chromatography after 24 ± 8 h of chemotherapy, and individual paclitaxel time above a threshold concentration of 0.05 µmol/L (Tc>0.05 ) was calculated using the population pharmacokinetic model. Haematological and non-haematological toxicities were monitored after chemotherapy, and the correlation between different chemotherapy toxicities and Tc>0.05 was evaluated using the Prism software. RESULTS AND DISCUSSION: The enrolled patients were divided into the hypoalbuminemia group and normal albumin level group. The mean Tc>0.05 values in the normal albumin level and hypoalbuminemia groups were 36.89 and 24.93 h, respectively (P < 0.001). The risk of myelosuppression was positively correlated with Tc>0.05 . Due to the lower Tc>0.05 , the incidences of immediate AEs such as gastrointestinal reactions and rashes were higher in the hypoalbuminemia group than in the normal albumin level group, and the incidences of delayed AEs such as myelosuppression and neurotoxicity were lower in the hypoalbuminemia group. WHAT IS NEW AND CONCLUSIONS: Plasma albumin level has a conclusive effect on Tc>0.05 , which can predict the potential clinical toxicity of paclitaxel. The study provides a theoretical basis for administration of paclitaxel.

RESUMEN

OBJECTIVE: Second-line (2L) chemotherapy is important for improved survival in patients with advanced pancreatic cancer (APC). However, approximately half of patients with APC do not receive 2L chemotherapy because of disease progression or adverse events. Baseline factors predictive of the receipt of 2L chemotherapy remain unknown. Therefore, we investigated predictive factors for the receipt of 2L chemotherapy in patients with APC. METHODS: Between January 2015 and March 2020, 53 patients with APC received nab-paclitaxel plus gemcitabine (AG) as first-line chemotherapy at our institute. Of these 53 patients, 29 patients received 2L chemotherapy, and 23 patients received best supportive care. Patients' characteristics were compared retrospectively, and predictive factors for the receipt of 2L chemotherapy were evaluated. RESULTS: Sarcopenia and hypoalbuminemia at baseline were independent negative predictive factors for the receipt of 2L chemotherapy in multivariate analysis. Although the presence of sarcopenia did not affect the relative dose intensity through 8 weeks of AG therapy, patients with hypoalbuminemia had a significantly lower relative dose intensity. CONCLUSIONS: Sarcopenia and hypoalbuminemia at baseline might be negative predictive factors for the receipt of 2L chemotherapy after AG treatment in patients with APC.

RESUMEN

BACKGROUND: Peptide receptor radionuclide therapy (PRRT) with radiolabeled somatostatin receptor (SSR) analogs is now an established systemic treatment for neuroendocrine tumors (NET). However, more short- and long-term data about renal and hepatotoxicity is needed. Here we present our experience in this clinical scenario. METHODS: Eighty-six patients with progressive SSR-expressing malignancies underwent PRRT with Lu-177 Dotatate and were followed up for up to 2 years. Laboratory tests were done 1 week before each cycle and every 2 months at follow-up. Hepatic and renal toxicity was determined based on NCI CTCAE V5.0. RESULTS: 55/86 (64%) patients completed all 4 cycles of PRRT; 18/86 (20.9%) are currently being treated; 13/86 (15.1%) had to discontinue PRRT: 4/13 (31%) due to hematologic toxicity, 9/13 (69%) due to non-PRRT-related comorbidities. Out of the patients who finished treatment, only transient grade 2 toxicities were observed during PRRT: hypoalbuminemia in 5.5% (3/55), and renal toxicity (serum creatinine and estimated glomerular filtration rate) in 1.8% (1/55). No grade 3 or 4 liver and renal toxicity occurred. Patients presenting with impaired liver or renal function prior to PRRT, either improved or had stable findings. No deterioration was observed. CONCLUSION: Peptide receptor radionuclide therapy does not have a negative impact on liver and renal function, even in patients with pre-existing impaired parameters. No grade 3 or 4 hepatic or renal toxicity was identified. Only transient grade 2 hypoalbuminemia in 5.5% and nephrotoxicity in 1.8% of patients were seen during PRRT.

RESUMEN

Older age and poor performance status lead to worse outcomes in acute myeloid leukemia (AML) patients. Hypoalbuminemia is a negative predictor of morbidity and mortality in several malignancies. We evaluated the relationship between baseline serum albumin levels on treatment-related complications, as well as short-term mortality and overall survival (OS) in 756 newly diagnosed AML patients. We conducted a retrospective multicenter study to examine treatment-related complications and OS according to pretreatment serum albumin levels: normal albumin ≥3.5 g/dl, marked hypoalbuminemia <2.5 g/dl, and hypoalbuminemia 2.5-3.4 g/dl. In an adjusted multivariate analysis, a lower baseline albumin was independently associated with a higher number of grade ≥3 complications when adjusting for age, secondary AML, sex and intensive treatment. When comparing normal to markedly low albumin levels, the estimated mean number of complications increases by a factor of 1.35. Patients who had a normal baseline albumin had a 30 day-mortality rate of 4.8%, which was significantly lower compared with patients with hypoalbuminemia (16.5%) and marked hypoalbuminemia (33.9%; p < 0.01). Similarly, 60-day mortality rate was significantly higher in the hypoalbuminemia group (24.0%) and marked hypoalbuminemia group (45%) compared with normal albumin group (8.3%; p < 0.01). Patients with lower baseline albumin levels have increased treatment-related morbidity and mortality, suggesting that pre-treatment serum albumin is an important independent prognostic marker.

RESUMEN

PURPOSE: To evaluate the safety and efficacy of remdesivir in adult patients with COVID-19. METHODS: PubMed, Embase, Scopus, Web of Science, Cochrane Library, ClinicalTrials.gov, and medRxiv databases were searched using a search strategy tailored to each database. The Consolidated Standards of Reporting Trials (CONSORT) and Strengthening the reporting of observational studies in epidemiology (STROBE) checklists were used for the studies' qualitative assessment. The outcomes studied were mortality, all adverse events, serious adverse events, and clinical improvement. The quantitative synthesis was conducted using fixed and random effects models in the CMA 2.2. Heterogeneity was tested using the I-squared (I2) measure. RESULTS: In general, six studies, including five randomized controlled trials and one cohort study were found eligible. Comparison of the findings related to both groups receiving remdesivir (10-day remdesivir group) and placebo/control group showed that remdesivir treatment had no significant effect on mortality at day 14 of the treatment (RR=0.769; 95% CI :0.563-1.050; p=0.098), and all adverse events (RR= 1.078; 95% CI: 0.908-1.279; p= 0.392). However, remdesivir had a significant effect on clinical improvement at day 14 compared to placebo/control (OR= 1.447; 95% CI: 1.005-2.085; p= 0.047) and reduced serious adverse events (RR= 0.736; 95% CI: 0.611-0.887; p= 0.001). CONCLUSION: Remdesivir has positive effects on clinical improvement, and reduction of the risk of serious adverse events. However, it does not influence the mortality at day 14 of treatment.

RESUMEN

Cow's milk is a key component of a child's diet. While the consumption of even trace amounts can result in allergy to its proteins and/or hypolactasia, excessive cow's milk consumption can result in numerous health complications, including iron deficiency, due to the diet being improperly balanced. Although the incidence of iron deficiency has declined, it remains the most widespread nutritional deficiency globally and the most common cause of anemia. One rare consequence of anemia caused by iron deficiency is protein-losing enteropathy; however, the mechanisms of its development are unclear. The following manuscript, based on a literature review, presents two rare cases of children, a 16-month-old boy and a 2.5-year-old girl, who developed severe microcytic anemia, enteropathy with hypoalbuminemia, and anasarca as a result of excessive cow's milk consumption. It highlights the possible relationship between excessive consumption of cow's milk in children and severe iron deficiency anemia with accompanying hypoalbuminemia; it may also result in serious clinical conditions, even in children that do not demonstrate food hypersensitivity.

RESUMEN

A 69-year-old man underwent total laryngopharyngectomy with radial forearm free flap reconstruction. He had lost 15 kg over a period of 6 months and did not receive any preoperative nutritional workup or management. The patient had a general total intravenous anesthetic with ketamine, lidocaine, and propofol, which was uneventful for an 8-hour surgery. The patient remained deeply sedated for 4 hours after discontinuation of all sedative medications. Diagnostic workup only revealed hypoalbuminemia and hypoproteinemia. We hypothesized relative overdosage of sedative anesthetic drugs due to preoperative malnutrition accentuated by intraoperative fluid administration.

RESUMEN

Serum albumin (SA) level is a powerful cardiovascular prognostic marker, suggested to be involved in regulation of platelet function. High on-aspirin platelet reactivity (HAPR) is associated with increased risk for deleterious cardiovascular events. The aim of the present study was to evaluate the association between HAPR and albumin levels in patients with stable coronary artery disease (CAD) treated with aspirin. Patients with known stable CAD, who were taking aspirin (75 to 100 mg qd) regularly for at least 1 month, were screened for the present study. Exclusion criteria: cancer, sepsis or acute infection, active inflammatory/rheumatic disease, recent major surgery, chronic liver failure, the administration of other antiplatelet drugs, nonadherence with aspirin and thrombocytopenia. Blood was drawn from the participants and sent for SA level and platelet function test (VerifyNow). HAPR was defined as aspirin reaction units (ARU) >550. Overall 116 patients were analyzed; age 69 ± 10, 28% women. Twenty (17%) were hypoalbuminemic (≤3.5 g/dl). Hypoalbuminemic patients had similar characteristics to the normal albumin group except mildly higher creatinine in the former. SA levels were significantly lower in the hypoalbuminemic group (3.2 ± 0.2 g/dl vs 4.2 ± 0.4 g/dl, respectively, p <0.001) whereas mean ARU was significantly higher compared with the normal albumin group (548 ± 45 vs 444 ± 66 ARU, respectively, p <0.001). A significant inverse association was observed between SA and ARU with (R2 = 0.67, p <0.001). Multivariate analysis adjusted for potential confounders found that albumin ≤3.5 is the strongest predictor of HAPR in patients with stable CAD (hazards ratio 4.9, 95% confidence interval 2.2 to 32, p = 0.002). In conclusion, hypoalbuminemia is strongly associated with HAPR in patients with stable CAD.

RESUMEN

BACKGROUND: PI3K pathway activation is common in endometrial cancer. We evaluated the safety and efficacy of the dual PI3K/mTOR inhibitor, LY3023414, in patients with advanced endometrial cancer harboring activating mutations in the PI3K pathway. METHODS: We conducted a single-arm phase 2 study of monotherapy LY3023414. Eligible patients had advanced endometrial cancer of any grade, prior management with 1-4 cytotoxic lines, and PI3K pathway activation prospectively defined as a loss-of-function PTEN alteration or activating alteration in PIK3CA, AKT1, PIK3R1, PIK3R2, or MTOR. The primary objective was best overall response rate (ORR) per RECIST 1.1. RESULTS: Twenty-eight patients were treated; histologies included endometroid (39%), carcinosarcoma (25%), serous (21%), and mixed (14%). Patients were heavily pretreated, with a median of 2 prior cytotoxic lines (range, 1-3). The most common alterations involved PIK3CA (68%), PTEN (43%), and PIK3R1 (32%). In the 25 efficacy-evaluable patients, the ORR was 16% (90% CI, 7%-100%), and the clinical benefit rate was 28% (90% CI, 16%-100%). Four patients had a confirmed partial response, and 2 responses lasted for >9 months. The median progression-free survival and overall survival were 2.5 months (95% CI, 1.2-3.0) and 9.2 months (95% CI, 5.0-15.9), respectively. The most common all-grade treatment-related adverse events were anemia (71%), hyperglycemia (71%), hypoalbuminemia (68%), and hypophosphatemia (61%). No correlation between molecular alterations and response was observed. CONCLUSION: In patients with heavily pretreated advanced endometrial cancer prospectively selected for tumors with activating PI3K pathway mutations, LY3023414 demonstrated modest single-agent activity and a manageable safety profile.

RESUMEN

PURPOSE: Preoperative chemotherapy is an effective treatment option for resectable gastric cancer, but it is associated with various adverse events (AEs). This study aimed to identify the body composition parameters that most accurately predicted the incidence of AEs in preoperative chemotherapy for gastric cancer. METHODS: The present study included a total of 114 patients who received preoperative chemotherapy for resectable gastric cancer. We estimated various body composition parameters using computed tomography images obtained before preoperative chemotherapy. Their associations with the incidence of hematological (grade ≥ 3) and non-hematological (grade ≥ 2) AEs were analyzed by multivariate logistic regression analyses. RESULTS: Seventy-two of the 114 (63.2%) patients experienced hematological AEs (grade ≥ 3), specifically neutropenia in 68 (59.6%), anemia in 5 (4.9%), and thrombocytopenia in 3 (2.6%). Meanwhile, 59 patients (51.8%) experienced non-hematological AEs (grade ≥ 2), namely hypoalbuminemia in 31 (27.2%), anorexia in 24 (21.1%), and febrile neutropenia in 17 (14.9%). Multivariate analyses revealed that a low psoas muscle index (PMI) was an independent risk factor for the incidence of both hematological and non-hematological AEs. CONCLUSIONS: Patients with a low PMI experienced an increased incidence of hematological and non-hematological toxicities during preoperative chemotherapy for gastric cancer. Clinicians should be aware of these risks in this population.

RESUMEN

Carfilzomib-lenalidomide-dexamethasone (KRd) therapy has yielded promising results in patients with newly diagnosed multiple myeloma (NDMM). Cereblon (CRBN) is the direct molecular target of lenalidomide and genetic polymorphisms in CRBN have been associated with lenalidomide efficacy. In this study, we assessed the correlation of five single nucleotide variants (SNVs) in the CRBN gene with clinical response and outcomes in patients with NDMM administered KRd therapy with lenalidomide maintenance, achieving favorable trial endpoints in a prospective Phase II study (NCT01402284). Of the observed SNVs, no associations with KRd therapy response were found in this patient cohort, although strong trends in hypoalbuminemia grade and hyperbilirubinemia grade emerged across the CRBN rs1672753 genotype (P = 0.0008) and the rs1714327 genotype (P = 0.0010), respectively. Our results do not provide conclusive support for the predictive utility of CRBN gene polymorphisms as potential biomarkers of clinical response to lenalidomide-based therapy in our patient population. However, these findings remain to be validated in prospective studies using larger patient populations.

RESUMEN

Hypoalbuminemia is often observed in patients receiving chemotherapy for gastric cancer. The risk of hematologic toxicity is increased by the pharmacokinetic alteration of paclitaxel(PTX)owing to high serum protein binding in patients with hypoalbuminemia. Here, we examined the relationshipbetween the frequency of GradeB3 neutropenia and serum albumin concentration in 30 patients receiving PTX monotherapy, and 29 patients receiving PTX plus ramucirumab(RAM)combination therapy-a second-line treatment for advanced/recurrent gastric cancer. The number of patients who developed GradeB3 neutropenia was 8(27%)and 14(48%)of those who received monotherapy and combination therapy, respectively, with mean serum albumin concentrations of 3.31 g/dL and 3.15 g/dL, respectively. Serum albumin concentrations were significantly lower in the GradeB3 neutropenia group than in the non-GradeB3 neutropenia group in both regimens. When the serum albumin concentration of patients receiving PTX or PTX plus RAM was below the cut-off values of 3.75 g/dL and 3.45 g/dL, respectively, the odds ratio of GradeB3 neutropenia was 12.25 and 7.33, respectively. Hypoalbuminemia was associated with the development of chemotherapy-induced GradeB3 neutropenia, in patients with gastric cancer treated with either PTX monotherapy or PTX plus RAM combination therapy. Therefore, not only neutrophils but also serum albumin concentration should be monitored during chemotherapy.

RESUMEN

BACKGROUND: Venous thromboembolism (VTE) is highly associated with advanced gastric cancer (AGC) and is sometimes lethal. Predictors of VTE have not been identified, and the efficacy and safety of direct oral anticoagulants (DOACs) for AGC-associated VTE remain to be clarified. METHODS: A total of 188 AGC patients who started chemotherapy during the period from January 2014 to December 2017 in our institutions were retrospectively examined for the incidence of VTE, risk factors for VTE, and the efficacy and safety of DOAC-based anticoagulant therapy for VTE. RESULTS: Thirty-four patients (18%) were diagnosed with VTE at the start or during the course of chemotherapy (VTE group). More VTE group patients had a history of abdominal surgery and had moderate-severe ascites (32% versus 17%, 32% versus 14%, respectively) than non-VTE group patients (NVTE group). The mean serum albumin concentrations in the VTE group were significantly lower than NVTE group (3.38 mg/dL vs 3.65 mg/dL, respectively). Multivariate analysis showed that hypoalbuminemia was significantly correlated with VTE (P = 0.012). In the VTE group, 29 patients (85%) received anticoagulant therapy, including 24 patients treated with DOACs. No lethal VTE was observed in any patients. Thirteen patients (45%) terminated DOACs because of anemia or bleeding events, of whom eleven developed major bleeding. Median overall survivals of the VTE and NVTE groups were 9.63 months and 11.5 months, respectively (P = 0.262). CONCLUSION: Hypoalbuminemia appears to be a risk factor for AGC-associated VTE. DOACs are effective to AGC-associated VTE, but careful observation of bleeding events is required.

RESUMEN

A phase 3, multicenter, open-label, 52-week study investigated the efficacy and safety of adalimumab 80 mg at week 0 followed by adalimumab 40 mg every other week (option to escalate to 80 mg when necessary) in Japanese patients with generalized pustular psoriasis (GPP). Adults (aged 15-75 years) with GPP, total skin score (overall erythema area, erythema area with pustules, and edema area) of 3 or more, and erythema with pustules (skin score, ≥1) based on the 2014 Japanese Dermatological Association severity index of GPP were enrolled. The primary efficacy end-point was clinical response at week 16 (non-responder imputation), defined as achieving remission (total skin score, 0) or improvement from baseline (reduction of ≥1 point from a baseline total skin score of 3 or ≥2 points from a baseline total skin score of ≥4). Of 10 enrolled patients (mean disease duration, 10.6 years), seven patients, including three with the dose escalated to 80 mg every other week before week 15, achieved clinical response at week 16, and five achieved clinical response at week 52. Mean change from baseline total GPP score was -4.6 at week 16 (n = 8) and -6.0 at week 52 (n = 5); change in total skin score was -3.1 (n = 8) and -4.2 (n = 5), respectively. Nine patients experienced one or more adverse events and three experienced serious adverse events. The most common adverse events were nasopharyngitis, pruritus and hypoalbuminemia. In conclusion, adalimumab was effective and well tolerated for up to 52 weeks in the treatment of Japanese patients with GPP.
