RESUMEN

BACKGROUND: Targeting pituitary adenylate cyclase-activating polypeptide (PACAP) is a new avenue for treating migraine. The efficacy and safety of intravenous Lu AG09222, a humanized monoclonal antibody directed against the PACAP ligand, for migraine prevention are unclear. METHODS: In a phase 2, double-blind, randomized, placebo-controlled trial, we enrolled adult participants (18 to 65 years of age) with migraine for whom two to four previous preventive treatments had failed to provide a benefit. The trial included a 4-week treatment period and an 8-week follow-up period. Participants were randomly assigned in a 2:1:2 ratio to receive a single-dose baseline infusion of 750 mg of Lu AG09222, 100 mg of Lu AG09222, or placebo. The primary end point was the mean change from baseline in the number of migraine days per month, during weeks 1 through 4, in the Lu AG09222 750-mg group as compared with the placebo group. RESULTS: Of 237 participants enrolled, 97 received 750 mg of Lu AG09222, 46 received 100 mg of Lu AG09222, and 94 received placebo. The mean number of baseline migraine days per month was 16.7 in the overall population, and the mean change from baseline over weeks 1 through 4 was -6.2 days in the Lu AG09222 750-mg group, as compared with -4.2 days in the placebo group (difference, -2.0 days; 95% confidence interval, -3.8 to -0.3; P = 0.02). Adverse events with a higher incidence in the Lu AG09222 750-mg group than in the placebo group during the 12-week observation period included coronavirus disease 2019 (7% vs. 3%), nasopharyngitis (7% vs. 4%), and fatigue (5% vs. 1%). CONCLUSIONS: In a phase 2 trial, a single intravenous infusion of 750 mg of Lu AG09222 showed superiority over placebo in reducing migraine frequency over the subsequent 4 weeks. (Funded by H.

RESUMEN

BACKGROUND: It is common for patients on venovenous extracorporeal membrane oxygenation (VV ECMO) to require continuous renal replacement therapy (CRRT). This can be done using separate vascular access for the CRRT circuit, by placing the CRRT hemofilter within the ECMO circuit, or through a separate CRRT circuit connected to the ECMO circuit. When a CRRT circuit is connected to the ECMO circuit, the inflow and outflow CRRT limbs can both be placed pre-ECMO pump or the CRRT circuit can span the ECMO pump, with the CRRT inflow post-ECMO pump and the outflow pre-ECMO pump. Both configurations require the CRRT alarms to be inactivated due to high positive pressure experienced post-pump and low negative pressure pre-pump. We describe a novel technique that does not require separate venous access and still allows the CRRT alarms to be activated. TECHNIQUE: The CRRT inflow line is connected to the post-oxygenator de-airing port. The CRRT outflow line is connected to the pre-pump side of the ECMO circuit. Pigtails allow for these connections and act as resistors negating the large range of pressures generated by the ECMO centrifugal pump. RESULTS: We implemented this configuration in 11 patients with 100% success rate allowing for alarms to be maintained in all patients. The median number of interruptions per 100 CRRT days was 11.7. The median CRRT filter lifespan was 2.2 days, and the average blood flow was maintained at 311 mL/min. CONCLUSIONS: This configuration allows for efficient use of CRRT in ECMO patients while maintaining the safety alarms on the CRRT machine.

RESUMEN

INTRODUCTION: The Protek Duo (PtD) dual lumen, single cannula was developed as a percutaneous system for temporary mechanical support, inserted through the internal jugular vein (IJ) for both atrial inflow and pulmonary artery outflow. Outcomes of PtD compared to alternative Peripheral Right Ventricular Assist Device (pRVAD) methods are limited. METHODS: A retrospective analysis was conducted of pRVAD recipients from January 2017 - February 2022 (n = 111). These were classified into PtD (n = 52) patients and Non-Protek [(N-PtD) (n = 59)] recipients undergoing cannulation of the IJ and femoral vein. Results were further stratified by indication for pRVAD support: cardiogenic etiologies of heart failure and progressive ARDS. RESULTS: No survival benefit was detected between PtD and N-PtD groups at 1-week (OR: 1.32, 95% CI: 0.49-3.56, p = 0.58) or 6-month (OR: 9.83, 95% CI: 0.37-1.84, p = 0.64) follow-up. There were no statistically significant differences in whether patients' mobility progressed to out-of-bed activity (p = 0.26) or ambulation (p = 0.38). No differences were noted in time to out-of-bed (p = 0.26) or time to ambulation (p = 0.36). On subgroup analysis of patients by indication for pRVAD cannulation, these results persisted; no difference was noted in mid-term mortality (Cardiogenic: p = 0.39; ARDS: p = 0.91), progression to out-of-bed (p = 0.59; p = 1.00), or ambulation (p = 0.51; p-0.68). Among secondary outcomes, PtD patients had an increased dialysis requirement (p = 0.02). There were no differences in ability to wean from RVAD (p = 0.06), tracheostomy (p = 0.88), major bleeding events (p = 0.57), stroke (p = 0.58), or hospital length of stay (p = 0.39). CONCLUSIONS: Outcomes with PtD are comparable to those of traditional pRVAD cannulation strategies. Of note, no mobility benefit was observed to the use of PtD across several metrics.

RESUMEN

BACKGROUND: For some people with migraine, despite taking greater amounts of acute headache medication (AHM), they develop an increase in monthly headache days. This cycle of increasing headache days, and in turn AHM use, can lead to a secondary headache disorder called medication-overuse headache (MOH). Preventive medications can prevent migraine from occurring and reduce reliance on AHMs, thereby preventing the cycle of MOH. This study was performed to evaluate the efficacy and safety of eptinezumab to prevent migraine/headache in a mainly Asian patient population with a dual diagnosis of chronic migraine and MOH. METHODS: SUNLIGHT was a phase 3, multicenter, double-blind, parallel-group, placebo-controlled trial. Patients aged 18-75 years with ≥ 8 migraine days/month and a diagnosis of MOH were randomly allocated (1:1) to one of two treatment groups: eptinezumab 100 mg or placebo. Monthly migraine days (MMDs) were captured using a daily electronic diary; the change from baseline in the number of MMDs over Weeks 1-12 was the primary efficacy endpoint. RESULTS: Patients were randomized to eptinezumab 100 mg (n = 93) or placebo (n = 100). Over Weeks 1-12, eptinezumab reduced mean MMDs more than placebo (difference between treatments was -1.2; p = 0.1484). Differences between treatment groups with p-values below 0.05 favoring eptinezumab were observed in 3 out of the 6 key secondary endpoints. CONCLUSION: All endpoints numerically favored eptinezumab treatment when compared to placebo; however, this study did not meet its primary endpoint and is therefore negative. No new safety signals were identified in this study, like previous reports that confirmed the safety and tolerability of eptinezumab treatment. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04772742 (26/02/2021).

RESUMEN

BACKGROUND: Analysis of efficacy and tolerability of vortioxetine 20 mg/day, and optimal timing of dose adjustment, in patients with major depressive disorder (MDD). METHODS: Pooled analysis of six randomized, fixed-dose studies of vortioxetine 5 to 20 mg/day. Mean change from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) total score was analyzed by vortioxetine dose using a mixed model for repeated measures. Tolerability was assessed over the 8-week treatment period and from day 8 (ie, following dose increase to 20 mg/day). Data from three randomized, flexible-dose studies were examined for frequency and timing of dose adjustment. RESULTS: A clear dose-response relationship for vortioxetine was confirmed in terms of improvement in MADRS total score. Significant differences vs placebo were seen for vortioxetine 20 mg/day from week 2 onwards; vortioxetine 10 mg did not separate from placebo until week 4. At week 8, mean change in MADRS total score from baseline was significantly greater for vortioxetine 20 mg/day vs 10 mg/day (difference, -1.03 points; P < .05). Incidence of adverse events was not increased in patients who received vortioxetine 20 mg/day vs 10 mg/day. In flexible-dose studies, dosage was increased to 20 mg/day after 1 week in 48.0% of patients; final dosage was 20 mg/day in 64.3% of patients. CONCLUSIONS: Vortioxetine 20 mg is significantly more effective than vortioxetine 10 mg in patients with MDD, with a similar tolerability profile. In flexible-dose studies, almost half of all patients received 20 mg/day after 1 week and two-thirds received 20 mg/day as their final dosage.

RESUMEN

BACKGROUND: Vortioxetine has demonstrated dose-dependent efficacy in patients with major depressive disorder (MDD), with the greatest effect observed with vortioxetine 20 mg/day. This analysis further explored the clinical relevance of the more rapid and greater improvement in depressive symptoms observed with vortioxetine 20 mg/day vs 10 mg/day. METHODS: Analysis of pooled data from six short-term (8-week), randomized, placebo-controlled, fixed-dose studies of vortioxetine 20 mg/day in patients with MDD (N = 2620). Symptomatic response (≥50% decrease in Montgomery-Åsberg Depression Rating Scale [MADRS] total score), sustained symptomatic response, and remission (MADRS total score ≤10) were assessed by vortioxetine dosage (20 or 10 mg/day). RESULTS: After 8 weeks, 51.4% of patients receiving vortioxetine 20 mg/day had achieved symptomatic response vs 46.0% of those receiving vortioxetine 10 mg/day (P < .05). Significantly more patients achieved symptomatic response vs placebo from week 2 onwards for vortioxetine 20 mg/day and from week 6 onwards for vortioxetine 10 mg/day (both P ≤ .05). Sustained response was achieved from week 4 for 26.0% of patients receiving vortioxetine 20 mg/day vs 19.1% of those receiving vortioxetine 10 mg/day (P < .01), increasing to 36.0% and 29.8%, respectively, over the 8-week treatment period (P < .05). At week 8, 32.0% of patients receiving vortioxetine 20 mg/day were in remission vs 28.2% of those receiving vortioxetine 10 mg/day (P = .09). Rates of adverse events and treatment withdrawal were not increased during the week following vortioxetine dose up-titration to 20 mg/day. CONCLUSION: Vortioxetine 20 mg/day provides more rapid and more sustained symptomatic response than vortioxetine 10 mg/day in patients with MDD, without compromising tolerability.

RESUMEN

BACKGROUND: Vortioxetine is an approved antidepressant that has also demonstrated positive effects on anxiety symptoms in subjects with generalized anxiety disorder (GAD). This post-hoc analysis evaluates the efficacy of vortioxetine in GAD subjects who are working and/or pursuing an education. METHODS: In study NCT00744627, 301 GAD subjects were randomized to vortioxetine 5 mg or placebo for 8 weeks. Efficacy measures included the Hamilton Anxiety Rating Scale (HAM-A) total score, response/remission, global functioning (Sheehan Disability Scale [SDS]), and quality of life (Short Form-36 Health Survey). In study NCT00788034, 687 GAD subjects were treated open-label with vortioxetine 5 or 10 mg for 20 weeks, after which subjects in remission were randomized to fixed-dose of vortioxetine (5 or 10 mg) or placebo for at least 24 weeks. The primary endpoint was time to relapse. Analyses were completed in subjects working and/or pursuing an education at study entry and the full analysis set. RESULTS: In study NCT00744627, the effect of vortioxetine versus placebo on HAM-A total score was -4.3 (p=0.0005) in working subjects (60% of total), while the effect in the total population was -3.8 (p=0.0001). The effect was greatest in subjects in professional (-4.5, p=0.0130) and associate professional positions (-7.6, p=0.0086). Greater effects in terms of response, remission, and the SDS and SF-36 were also observed. In NCT00788034, working subjects (69% of total) randomized to placebo were significantly more likely to relapse than subjects treated with vortioxetine (hazard ratio=2.9; p<0.001), while the hazard ratio in the total population was 2.7 (p<0.0001). CONCLUSIONS: The beneficial effects of vortioxetine on anxiety symptoms, functioning, and quality of life are greater in adults with GAD who are working and/or pursuing an education versus the full GAD study population.

RESUMEN

BACKGROUND: Patients with major depressive disorder (MDD) often experience comorbid anxiety symptoms. Vortioxetine has demonstrated efficacy in treating anxiety symptoms in patients with MDD; however, efficacy and tolerability have not been assessed across the entire approved dosage range. METHODS: The efficacy and tolerability of vortioxetine 5-20 mg/day were assessed in patients with MDD and high levels of anxiety symptoms (Hamilton Anxiety Rating Scale [HAM-A] total score ≥ 20) using pooled data from four randomized, fixed-dose, placebo-controlled studies (n = 842). Data from a randomized, double-blind study of vortioxetine 10-20 mg/day versus agomelatine 25-50 mg/day in patients with an inadequate response to prior therapy (n = 299) were analyzed separately. Mean changes from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS), HAM-A, and Sheehan Disability Scale (SDS) total scores were analyzed by vortioxetine dosage. RESULTS: The pooled analysis of fixed-dose studies demonstrated a clear dose-response relationship for vortioxetine 5-20 mg/day for improvements in MADRS, HAM-A, and SDS total scores. Vortioxetine 20 mg/day demonstrated significant effects versus placebo from week 4 onwards. In the post-hoc analysis of the active-controlled study in patients with an inadequate response to prior therapy, vortioxetine 10-20 mg/day was superior to agomelatine across all outcome measures from week 4 onwards. Up-titration of vortioxetine to 20 mg/day was not associated with an increase in adverse events. LIMITATIONS: Short-term trials. CONCLUSIONS: Vortioxetine is efficacious and well tolerated in patients with MDD and high levels of anxiety symptoms, including those with an inadequate response to prior therapy. The greatest therapeutic benefits were observed with vortioxetine 20 mg/day. TRIAL REGISTRATION: NCT01140906, NCT01153009, NCT01163266, NCT01255787, NCT01488071.

RESUMEN

Objective: To compare the efficacy of vortioxetine and the serotonin-norepinephrine reuptake inhibitor (SNRI) desvenlafaxine in patients with major depressive disorder (MDD) experiencing partial response to initial treatment with a selective serotonin reuptake inhibitor (SSRI).Methods: This randomized, double-blind, active-controlled, parallel-group, 8-week study of vortioxetine (10 or 20 mg/d; n = 309) versus desvenlafaxine (50 mg/d: n = 293) was conducted from June 2020 to February 2022 in adults with a DSM-5 diagnosis of MDD who experienced partial response to SSRI monotherapy. The primary endpoint was mean change from baseline to week 8 in Montgomery-Åsberg Depression Rating Scale (MADRS) total score. Differences between groups were analyzed using mixed models for repeated measures.Results: Non-inferiority of vortioxetine versus desvenlafaxine was established in terms of mean change from baseline to week 8 in MADRS total score; however, a numeric advantage was observed in favor of vortioxetine (difference, -0.47 MADRS points [95% CI, -1.61 to 0.67]; P = .420). At week 8, significantly more vortioxetine-treated than desvenlafaxine-treated patients had achieved symptomatic and functional remission (ie, Clinical Global Impressions-Severity of Illness scale [CGI-S] score ≤ 2) (32.5% vs 24.8%, respectively; odds ratio = 1.48 [95% CI, 1.03 to 2.15]; P = .034). Vortioxetine-treated patients also experienced significantly greater improvements in daily and social functioning assessed by the Functioning Assessment Short Test (P = .009 and .045 vs desvenlafaxine, respectively) and reported significantly greater satisfaction with their medication assessed by the Quality of Life Enjoyment and Satisfaction Questionnaire (P = .044). Treatment-emergent adverse events (TEAEs) were reported in 46.1% and 39.6% of patients in the vortioxetine and desvenlafaxine groups, respectively; these were mostly mild or moderate in intensity (> 98% of all TEAEs in each group).Conclusions: Compared with the SNRI desvenlafaxine, vortioxetine was associated with significantly higher rates of CGI-S remission, better daily and social functioning, and greater treatment satisfaction in patients with MDD and partial response to SSRIs. These findings support the use of vortioxetine before SNRIs in the treatment algorithm in patients with MDD.Trial Registration: ClinicalTrials.gov Identifier: NCT04448431.

RESUMEN

OBJECTIVES: Malignancy is the leading cause of late mortality after orthotopic heart transplantation (OHT), and the burden of post-transplantation cancer is expected to rise in proportion to increased case volume following the 2018 heart allocation score change. In this report, we evaluated factors associated with de novo malignancy after OHT with a focus on skin and solid organ cancers. METHODS: Patients who underwent OHT at our institution between 1999 and 2018 were retrospectively reviewed (n = 488). Terminal outcomes of death and development of skin and/or solid organ malignancy were assessed as competing risks. Fine-Gray subdistribution hazards regression was used to evaluate the association between perioperative patient and donor characteristics and late-term malignancy outcomes. RESULTS: By 1, 5 and 10 years, an estimated 2%, 17% and 27% of patients developed skin malignancy, while 1%, 5% and 12% of patients developed solid organ malignancy. On multivariable Fine-Gray regression, age [1.05 (1.03-1.08); P < 0.001], government payer insurance [1.77 (1.20-2.59); P = 0.006], family history of malignancy [1.66 (1.15-2.38); P = 0.007] and metformin use [1.73 (1.15-2.59); P = 0.008] were associated with increased risk of melanoma and basal or squamous cell carcinoma. Age [1.08 (1.04-1.12); P < 0.001] and family history of malignancy [2.55 (1.43-4.56); P = 0.002] were associated with an increased risk of solid organ cancer, most commonly prostate and lung cancer. CONCLUSIONS: Vigilant cancer and immunosuppression surveillance is warranted in OHT recipients at late-term follow-up. The cumulative incidence of skin and solid organ malignancies increases temporally after transplantation, and key risk factors for the development of post-OHT malignancy warrant identification and routine monitoring.

RESUMEN

Baking soda overdose is rarely reported. However, several cases have been previously documented, as baking soda has gained popularity as an over-the-counter remedy. The present study reported the case of a 69-year-old male patient hospitalized with metabolic alkalosis (pH 7.61; bicarbonate levels, 53.2 mEq/l), hypokalemia (K+ 2.6 mEq/l), acute kidney injury (serum creatinine level 4.02 mg/dl) and hepatic toxicity (alanine transaminase, 955 U/l; aspartate transaminase, 1,091 U/l) in the context of baking soda misuse as an alternative treatment for gout. The patient's past medical history included chronic uric acid nephropathy, gout, arterial hypertension and permanent atrial fibrillation. Under corrective treatment for the hydro-electrolyte and acid-base imbalances, the hepatic injury and inflammation markers were within normal limits; uric acid and creatinine serum levels also decreased.

RESUMEN

BACKGROUND: Insulin producing cells generated by liver cell transdifferentiation, could serve as an attractive source for regenerative medicine. The present study assesses the relationship between DNA methylation pTFs induced liver to pancreas transdifferentiation. RESULTS: The transdifferentiation process is associated with DNA demethylation, mainly at gene regulatory sites, and with increased expression of these genes. Active inhibition of DNA methylation promotes the pancreatic transcription factor-induced transdifferentiation process, supporting a causal role for DNA demethylation in this process. CONCLUSIONS: Transdifferentiation is associated with global DNA hypomethylation, and with increased expression of specific demethylated genes. A combination of epigenetic modulators may be used to increase chromatin accessibility of the pancreatic transcription factors, thus promoting the efficiency of the developmental process.

RESUMEN

INTRODUCTION: Inadequate treatment response and emotional blunting are common challenges with selective serotonin reuptake inhibitors/serotonin-noradrenaline reuptake inhibitors (SSRIs/SNRIs) for major depressive disorder (MDD). We investigated the effectiveness of vortioxetine on emotional blunting in patients with partial response to treatment with SSRIs/SNRIs. METHODS: Patients with MDD who experienced a partial response to SSRI/SNRI monotherapy at adequate dose for ≥6 weeks were switched to 8 weeks of vortioxetine treatment 10-20 mg/day (Study NCT03835715). Key inclusion criteria were Montgomery-Åsberg Depression Rating Scale (MADRS) total score >21 and <29, current major depressive episode <12 months, Oxford Depression Questionnaire (ODQ) total score ≥50, and confirmation of emotional blunting by standardized screening question. Emotional blunting was assessed by ODQ and depressive symptoms by MADRS. Other outcomes assessed included motivation and energy (Motivation and Energy Inventory [MEI]), cognitive performance (Digit Symbol Substitution Test [DSST]), and overall functioning (Sheehan Disability Scale [SDS]). RESULTS: At week 8, patients (N=143) had improved by -29.8 points (p<0.0001) in ODQ total score; 50% reported no emotional blunting in response to standardized screening question. Significant improvements were observed on the DSST, MEI, and SDS at all time points assessed, and 47% of patients were in remission (MADRS total score ≤10) at week 8. The most common treatment-emergent adverse events included nausea, headache, dizziness, vomiting, and diarrhea. LIMITATIONS: No prospective phase before medication switch. CONCLUSION: Vortioxetine 10-20 mg effectively improved emotional blunting, overall functioning, motivation and energy, cognitive performance, and depressive symptoms in patients with MDD with partial response to SSRI/SNRI therapy and emotional blunting.

RESUMEN

BACKGROUND: The Oxford Depression Questionnaire (ODQ) is a patient-reported scale for assessing emotional blunting in patients with major depressive disorder (MDD). This analysis was undertaken to further validate the scale in patients experiencing emotional blunting while receiving antidepressant treatment. METHODS: Patients with MDD who experienced inadequate depressive-symptom resolution and emotional blunting on selective serotonin reuptake inhibitor or serotonin-noradrenaline reuptake inhibitor monotherapy (adequate dose for ≥6 weeks) were switched to vortioxetine 10-20 mg/day. ODQ total scores were assessed excluding and including the "antidepressant-as-cause" domain (ODQ-20 and ODQ-26, respectively). Anchor- and distribution-based methods were used to determine the minimal clinically important difference in ODQ scores in terms of change from baseline to week 8 of antidepressant treatment. RESULTS: After 8 weeks of vortioxetine treatment, the mean change in ODQ-20 and ODQ-26 scores from baseline was -24.8 and -30.1 points, respectively. Greater mean changes from baseline in ODQ-20 and ODQ-26 scores were seen in patients reporting no emotional blunting vs those still experiencing emotional blunting after 8 weeks of vortioxetine treatment (ODQ-20: -27.0 vs -22.6 points; ODQ-26: -32.8 vs -27.5 points, respectively). In patients considered clinically minimally improved (Clinical Global Impression-Improvement score, 3) after 8 weeks of vortioxetine treatment, respective mean (standard deviation) change in ODQ-20 and ODQ-26 score from baseline was -15.5 (18.1) and -20.0 (20.5) points. LIMITATIONS: Short study duration. CONCLUSIONS: These results provide further validation of the clinical utility of the ODQ for assessing emotional blunting in patients with MDD. The suggested minimal clinically important difference for change in ODQ-20 and ODQ-26 scores is 16 and 20 points, respectively, after 8 weeks of antidepressant treatment.

RESUMEN

PURPOSE: This qualitative study explored patient perceptions of the most burdensome symptoms of major depressive disorder (MDD), the impact of symptoms on patients' daily lives, and patient expectations and experiences regarding the timing of onset of antidepressant pharmacotherapy. PATIENTS AND METHODS: Data were collected through facilitated, patient focus-group sessions in the USA between May and June 2019. Participants were adults with confirmed MDD who reported a major depressive episode within the past 2 years, for which they had received pharmacologic treatment for ≥6 weeks. The semi-structured discussion focused on the key topics of bothersome symptoms of MDD, the impact of symptoms on quality of life, and the effects of antidepressant treatment. Interviews were audio-recorded; findings were summarized using a content-analysis approach. RESULTS: Five focus-group sessions were undertaken, involving a total of 29 patients (each attended one session; mean age, 43.4 years; 72.4% female). Mean time since confirmed diagnosis of MDD was 13.1 years. The most commonly prescribed antidepressants received were bupropion (41.4% of participants), escitalopram (34.5%), and sertraline (34.5%). The most frequently reported bothersome MDD symptoms were fatigue (mentioned by 58.6% of participants), lack of motivation/loss of interest (51.7%), anxiety/panic (44.8%), sadness (41.4%), and lack of concentration/brain fog (41.4%). Socialization, family life, and work were the areas in which quality of life was most impacted. Participants expressed dissatisfaction with their antidepressant treatment. Fast symptom resolution was mentioned as a priority (defined as <1 week by 38.5% of participants and ≤1 month by 65.4%). Most participants had not experienced fast relief from their symptoms with current or previous antidepressant medications. CONCLUSION: Results of this qualitative study suggest that fatigue, anhedonia, cognitive symptoms, and anxiety are some of the most bothersome symptoms for patients with MDD and highlight the importance of obtaining rapid relief from these symptoms in order to improve outcomes and patient satisfaction with antidepressant medication.

RESUMEN

Autologous cells replacement therapy by liver to pancreas transdifferentiation (TD) allows diabetic patients to be also the donors of their own therapeutic tissue. Aim: To analyze whether the efficiency of the process is affected by liver donors' heterogeneity with regard to age, gender and the metabolic state. Materials & methods: TD of liver cells derived from nondiabetic and diabetic donors at different ages was characterized at molecular and cellular levels, in vitro. Results: Neither liver cells proliferation nor the propagated cells TD efficiency directly correlate with the age (3-60 years), gender or the metabolic state of the donors. Conclusion: Human liver cells derived from a wide array of ages and metabolic states can be used for autologous cells therapies for diabetics.
