RESUMEN

BACKGROUND: The clinical guidelines suggest that the dosing of cyclosporine (CsA), during combination therapy with paritaprevir/ritonavir-ombitasvir and dasabuvir (PrOD), would be only one-fifth of the pre-PrOD total daily dose to be administered once daily. However, this dosing may not be applicable to all patients depending on their clinical condition. This study focuses on the pharmacokinetic dynamics of PrOD with CsA in Asian organ transplant recipients with severe liver fibrosis or cirrhosis who undergo concurrent treatment with PrOD treatment and CsA. The efficacy and safety of PrOD treatment was also evaluated. METHODS: Data from 7 patients obtained between January 2017 and September 2017 were retrospectively analyzed. Determinations of the blood concentrations of CsA were made, whether used as a single treatment or in combination therapy with PrOD. RESULTS: The combination regimen compared with CsA administered alone resulted in a 4.53-fold and 5.52-fold increase in the area under the concentration-time curve from time 0-12 hours (AUC0-12 h) of CsA on days 1 and 15, respectively. In addition, the maximal concentration, time to maximum concentration, and terminal phase elimination half-life (t1/2) of CsA were increased during the combined treatment of PrOD and CsA. The authors proposed reducing the CsA dosage during PrOD treatment to one-seventh of that of the pre-PrOD treatment of the total daily dose to maintain target CsA levels. All patients achieved sustained virologic responses at week 12. There were no episodes of serious adverse events or graft rejections observed. CONCLUSIONS: Although the combination with PrOD significantly affects the pharmacokinetics of CsA, it is effective and safe with regular monitoring of the CsA blood concentrations and appropriate CsA dose adjustment.

RESUMEN

Breast cancer patients with high cholesterol biosynthesis signature had poorer therapeutic outcome. Cytochrome P450 (CYP) 2D6 is crucial in the oxidation of tamoxifen to generate active metabolites, 4-hydroxytamoxifen and endoxifen. CYP2D6 variants with C100T substitution encode null or poor functional proteins. This study aims to examine the association of C100T genotypes and serum lipid levels with plasma drug levels in patients. Plasma tamoxifen concentration was positively associated with serum triglyceride concentration, adjusting for age and C100T genotype. Overweight (body mass index >24.0) patients with high serum cholesterol (≥200 mg/dL) had increased risks of ineffective endoxifen levels (<5.97 ng/mL). Compared to the low-cholesterol group, the high-cholesterol group had a lower 4-hydroxytamoxifen or endoxifen level in T/T carriers. In T/T carriers, the high-cholesterol group had an increased risk of an ineffective endoxifen level. Metastasis, hot flash/flushing, and high alanine transaminase did not relate to plasma 4-hydroxytamoxifen or endoxifen levels. Results indicate that C100T and high serum cholesterol are risk factors of ineffective endoxifen levels in Taiwanese breast cancer patients. These findings warrant further studies of a large hypercholesterolemic population to examine the outcome of increased doses of tamoxifen.

RESUMEN

AIMS: This study aimed to assess retrospectively the efficacy and safety of cyclosporin A (CsA) therapy in patients with lupus nephritis (LN). MATERIALS AND METHODS: From September 2005 to August 2015, eligible patients with LN undergoing CsA treatment were enrolled in the study. Medical charts as well as clinical and laboratory data were retrospectively reviewed. The data were evaluated at 0, 1, 6, 12 month(s) after the start of CsA. Serum creatinine (SCr), estimated glomerular filtration rate (eGFR), urine protein/creatinine ratio (uPCR), complement components C3, C4, and anti-double stranded DNA antibody (anti-dsDNA) titers were recorded. Renal response to CsA (complete response (CR) and partial response (PR)) and relapse after stopping CsA were set as primary endpoint, and adverse events, progression to end-stage renal disease (ESRD), and all-cause mortality as secondary endpoint. RESULTS: Among 60 patients enrolled, 11.7%, 20%, 25% achieved CR and 65.0%, 51.7%, 40% achieved PR at 1, 6, and 12 months, respectively. The SCr and eGFR remained stable during follow-up. After 1 year, CsA led to a decrease in median uPCR (3.79 to 0.51, p < 0.001) and anti-dsDNA (10.1 to 5.7 IU/mL, p = 0.011), an increase in mean C3 (75.9 to 88.5 mg/dL, p < 0.001) and C4 (15.9 to 19.5 mg/dL, p < 0.001) as well as a decrease in glucocorticoid dose. There were no deaths or progression to ESRD originating from adverse events in our study. CONCLUSION: CsA is an effective and safe treatment for patients with LN. Further randomized controlled trials are needed.

RESUMEN

The integrated stress response (ISR) pathway is essential for adaption of various stresses and is related to mitochondrion-to-nucleus communication. Mitochondrial dysfunction-induced reactive oxygen species (ROS) was demonstrated to activate general control nonderepressible 2 (GCN2)⁻eukaryotic translation initiation factor 2α (eIF2α)⁻activating transcription factor-4 (ATF4) pathway-mediated cisplatin resistance of human gastric cancer cells. However, whether or how ISR activation per se could enhance chemoresistance remains unclear. In this study, we used eIF2α phosphatase inhibitor salubrinal to activate the ISR pathway and found that salubrinal reduced susceptibility to cisplatin. Moreover, salubrinal up-regulated ATF4-modulated gene expression, and knockdown of ATF4 attenuated salubrinal-induced drug resistance, suggesting that ATF4-modulated genes contribute to the process. The ATF4-modulated genes, xCT (a cystine/glutamate anti-transporter), tribbles-related protein 3 (TRB3), heme oxygenase 1 (HO-1), and phosphoenolpyruvate carboxykinase 2 (PCK2), were associated with a poorer prognosis for gastric cancer patients. By silencing individual genes, we found that xCT, but not TRB3, HO-1, or PCK2, is responsible for salubrinal-induced cisplatin resistance. In addition, salubrinal increased intracellular glutathione (GSH) and decreased cisplatin-induced lipid peroxidation. Salubrinal-induced cisplatin resistance was attenuated by inhibition of xCT and GSH biosynthesis. In conclusion, our results suggest that ISR activation by salubrinal up-regulates ATF4-modulated gene expression, increases GSH synthesis, and decreases cisplatin-induced oxidative damage, which contribute to cisplatin resistance in gastric cancer cells.

RESUMEN

BACKGROUND: Mothers with lifelong care responsibilities might involuntarily be non-employed or work part-time, both of which are defined as "underemployment." This study aimed to investigate who these underemployed mothers are and what are the factors associated with such employment hardship when having a child with intellectual disability (ID). METHOD: An interview survey was conducted in 2011 in two local authorities of Taiwan on 876 working-age mothers with a child with intellectual disability; 514 of them were working part-time/non-employed and chosen as participants of this study. RESULTS: The mothers with a younger child with intellectual disability, a higher level of education, a lower level of family income and more family members with disabilities were more likely to be underemployed compared with the mothers who were voluntarily working part-time/non-employed. CONCLUSIONS: The underemployed mothers were more likely to have financial difficulty and heavy caregiving loads; their employment hardship should be of concern for policymakers.

RESUMEN

OBJECTIVES: The level of 8-hydroxy-2-deoxyguanosise (8-OHdG) is a marker of oxidative stress. The objective of this study was to evaluate the effect of enzyme replacement therapy (ERT) on the level of 8-OHdG in patients with Fabry cardiomyopathy and the clinical evolution of Fabry cardiomyopathy. METHODS: We measured the serum levels of 8-OHdG in 20 healthy control and 22 patients with Fabry cardiomyopathy before and after ERT. RESULTS: The mean lysoGb3 and 8-OHdG levels was significantly increased in patients with Fabry cardiomyopathy compared with that of control subjects (lysoGb3, 3.6 ± 1.1 nM vs. 0.4 ± 0.1 nM, p < 0.01; 8-OHdG, 4.5 ± 0.5 ng/mL vs. 3.4 ± 0.4 ng/mL, P < 0.05). The mean lysoGb3 and 8-OHdG levels was significantly reduced after ERT for 14.2 months (lysoGb3, 3.6 ± 1.1 nM vs. 2.9 ± 1.1 nM, P < 0.05; 8-OHdG, 4.5 ± 0.5 ng/mL to 4 ± 0.4 ng/mL, P < 0.05). These changes were accompanied by decreases in LVM and LVMI. CONCLUSIONS: We demonstrated that the serum 8-OHdG levels is increased in patients with Fabry cardiomyopathy (FC) and that successful management of FC with ERT is associated with a decrease in this oxidative stress marker. Serum 8-OHdG levels can be used not only as a noninvasive biomarker of oxidative stress in patients with FC but also an objective and quantitative parameter in the follow-up of patients during ERT.

RESUMEN

PURPOSE: During the past two decades, many novel immunosuppressive drugs have been approved for transplant recipients. Trends in the use of maintenance immunosuppressants after liver transplantation in Asia are unclear. Thus, we aimed to analyze the prescription trends in maintenance immunosuppressive drugs among liver transplant recipients in Taiwan and compare the results with the trends reported from western countries. METHODS: We conducted a retrospective nationwide population-based study utilizing the National Health Insurance Research Database (NHIRD) to analyze the prescribing patterns of immunosuppressants used in Taiwanese liver transplant recipients from 2000 to 2009. RESULTS: A total of 1686 liver transplant patients and their prescriptions of immunosuppressants were analyzed. The 5-year survival rate of liver transplant recipients was 79.6%. In 2009, the major immunosuppressive therapy among liver transplant recipients was a dual-drug regimen with tacrolimus and mycophenolic acid (57.3%). Among the calcineurin inhibitors (CNI), the use of cyclosporine decreased from 58.9% to 12.5%, while the use of tacrolimus notably increased from 23.3% to 77.5%. The use of azathioprine decreased from 21.3% to 0.4%, while the use of mycophenolic acid increased from 56.1% to 76.5%. Among the mammalian target of rapamycin (mTOR) inhibitors, sirolimus was approved in 2002, and its use increased to 8.7% in 2009. In the first 3 months after liver transplantation, a total of 17 different regimens were used in 2009, compared with seven regimens in 2000. CONCLUSIONS: Although the CNI-based combination obviously remains the major regimen, our results reveal a trend toward individualized immunosuppressive regimens among Taiwanese liver transplant recipients.

RESUMEN

BACKGROUND: The universal breadwinner model means both parents are employed; while the universal caregiver model implies that the father's hours of caregiving are equal or higher to those of the mother. This study aims to examine the hypothesis that the universal caregiver model is more related to the overall well-being of mothers of children with intellectual disabilities than the universal breadwinner model. METHODS: Face-to-face interview surveys were conducted in 2011 in Taiwan with 876 working-age mothers who had an offspring with intellectual disabilities. The survey included 574 mothers living with their husbands who became our participants. RESULTS: Both anova and regression analyses indicated that, compared with mothers in the universal breadwinner group, mothers in the universal caregiver group had higher levels of maternal marital and family life satisfaction, but not of work satisfaction and quality of life. CONCLUSIONS: An incentive policy is critical for supporting the fathers involved in lifelong caregiving and to promote the mothers' quality of life.

RESUMEN

Studies comparing the sexual attitudes of men and women with intellectual disabilities (ID) have been limited. A mixed-methods approach was employed to explore attitudes toward sexuality among men and women with ID in Taiwan and to ascertain the disparities between attitudes among men and women with ID. First, fifty-six men and forty-four women with mild and moderate ID completed a face-to-face interview survey. After this, focus groups were conducted for men and women with ID. Results indicated that women with ID were more likely to have negative attitudes toward parenting and non-reproductive sexual behavior than their male counterparts. Qualitative data indicated that men and women with ID had different sexual attitudes and experiences and were subject to different expectations from people around them. Both men and women with ID had very limited opportunities to develop romantic relationships and a healthy sexual identity. Sexual rights awareness and practice should be matters of concern for this group of adults and women with ID in particular.

RESUMEN

AIM: Oral antifungal agent-induced liver injury is a common safety concern that may lead to patients' hesitation in treating fungal infections such as onychomycosis. This study evaluated risk of drug-induced liver injury (DILI) caused by oral antifungal agents in Taiwanese populations. METHODS: A population-based study was conducted by analyzing who used oral antifungal agents from 2002 to 2008 from the Taiwan National Health Insurance Database. A comparison control group was randomly extracted from the remainder of the original cohort. RESULTS: Of the 90,847 oral antifungal agents users, 52 patients had DILI. Twenty-eight DILI cases used ketoconazole, 12 fluconazole, eight griseofulvin, three itraconazole and two terbinafine. The incidence rates (IR) of DILI per 10,000 persons were 31.6, 4.9, 4.3, 3.6 and 1.6 for fluconazole, ketoconazole, griseofulvin, itraconazole and terbinafine, respectively. Longer exposure duration increased the risk of DILI, with IR for exposure duration ≥ 60 defined daily dose (DDD) of 170.9, 62.5, and 36.1 per 10,000 persons for ketoconazole, itraconazole and terbinafine, respectively. Patients taking antifungal agents had higher incidences of developing DILI compared with those in the control group after adjusting for age, gender and co-morbidities (relative risk 2.38, P < 0.001). All of the six patients with fatal DILI used fluconazole. Old age and fluconazole increased the risk of oral antifungal-induced fatal DILI. CONCLUSIONS: Oral antifungal agents are associated with low incidence of acute liver injury, but which may be fatal, especially for the elderly. Longer treatment duration may increase the risk of antifungal agent-induced liver injury, especially ketoconazole.

RESUMEN

PURPOSE: Significantly increasing heart transplantations have been performed in Taiwan in the past decades, but the trends of maintenance immunosuppression for heart transplant recipients have not been well known. In this study, we aimed to explore the trends of maintenance immunosuppressive therapy and common complications for heart transplant recipients. METHODS: We retrospectively analyzed ambulatory prescriptions in 488 heart transplant recipients for the period 2000-2009. Patient complications after heart transplantation were also identified. RESULTS: The annual number of new heart transplant recipients ranged from 18 to 68. The 5-year survival rate was 77.9%. The total number of regimens was 10 in 2000, and increased to 28 in 2009. Most prescriptions were immunosuppressive combinations (95.5%-89.5%). The majority of immunosuppressive regimens were a triple regimen: cyclosporine, mycophenolic acid and corticosteroid in 2009. Cyclosporine was a predominant calcineurin inhibitor with a decreasing trend from 73.9% to 59.1%, whereas the use of tacrolimus significantly increased from 11.9% to 38.4%. Mycophenolic acid was the most frequently used antimetabolite (60.1%-80.3%), while the use of azathioprine was reduced (21.6%-2.3%). From 2008, the launch of everolimus initiated a new era in the utilization of mammalian target of rapamycin inhibitors for maintenance immunosuppression. CONCLUSIONS: Cyclosporine remained the most frequently used calcineurin inhibitors, and tacrolimus increased gradually. Mycophenolic acid was the most popular antimetabolite rather than azathioprine. The rapidly increased everolimus combined regimen may change the patterns of maintenance immunosuppression. The increasing number of combination therapies indicates an active role of everolimus and a tendency of complex tailored individual therapies.

RESUMEN

The aim of the current study was to investigate the urban-rural disparity of prescribing generics, which were usually cheaper than branded drugs, within the universal health insurance system in Taiwan. Data sources were the cohort datasets of National Health Insurance Research Database with claims data in 2010. The generic prescribing ratios of dihydropyridine (DHP) derivatives (the proportion of DHP prescribed as generics to all prescribed DHP) of medical facilities were examined against the urbanization levels of the clinic location. Among the total 21,606,914 defined daily doses of DHP, 35.7% belonged to generics. The aggregate generic prescribing ratio rose from 6.7% at academic medical centers to 15.3% at regional hospitals, 29.4% at community hospital, and 66.1% at physician clinics. Among physician clinics, the generic prescribing ratio in urban areas was 63.9 ± 41.0% (mean ± standard deviation), lower than that in suburban (69.6 ± 38.7%) and in rural (74.1% ± 35.3%). After adjusting the related factors in the linear regression model, generic prescribing ratios of suburban and rural clinics were significantly higher than those of urban clinics (ß = 0.043 and 0.077; P = 0.024 and 0.008, resp.). The generic prescribing ratio of the most popular antihypertensive agents at a clinic was reversely associated with the urbanization level.

RESUMEN

While most drug policy researches paid attention to the financial impact of expensive drugs, the market situation of low-priced drugs in a country was seldom analyzed. We used the nationally representative claims datasets to explore the status within the National Health Insurance (NHI) in Taiwan. In 2007, a total of 12,443 distinct drug items had been prescribed 853,250,147 times with total expenditure of 105,216,950,198 new Taiwan dollars (NTD). Among them, 7,366 oral drug items accounted for 701,353,383 prescribed items and 68,133,988,960 NTD. Besides, 2,887 items (39.2% of oral drug items) belonged to cheap drugs with the unit price ≤ 1 NTD (about 0.03 of US dollar). While the top one item among all oral drugs had already a market share of 5.0%, 30 items 30.3% and 107 items 50.0%, the cheap drugs with aggregate 332,893,462 prescribed items (47.5% of all prescribed oral drug items) only accounted for 2,750,725,433 NTD (4.0% of expenditure for oral drugs and 2.6% of total drug expenditure). The drug market of Taiwan's NHI was abundant in cheap drugs. The unreasonably low prices of drugs might not guarantee the quality of pharmaceutical care and the sustainability of a healthy pharmaceutical industry in the long run.

RESUMEN

BACKGROUND: This study aimed to evaluate the effectiveness and safety of fixed-dose combination (FDC) inhaled corticosteroids/long-acting ß2-agonists (ICS/LABA) in bronchiectasis. RESEARCH DESIGN AND METHODS: A retrospective cohort study analyzed electronic medical records of bronchiectasis patients initiating ICS/LABA FDC or LAMA between 2007 and 2021. All bronchiectasis diagnoses were made by radiologists using high-resolution computed tomography. RESULTS: Of the 1,736 patients, 1,281 took ICS/LABA FDC and 455 LAMA. Among the 694 propensity score matched patients, ICS/LABA FDC had comparable outcomes to LAMA, with HRs of 1.22 (95% CI 0.81-1.83) for hospitalized respiratory infection, 1.06 (95% CI 0.84-1.33) for acute exacerbation, and 1.06 (95% CI 0.66-1.02) for all-cause hospitalization. Beclomethasone/formoterol (BEC/FOR) or budesonide/formoterol (BUD/FOR) led to a lower risk of acute exacerbation compared to fluticasone/salmeterol (FLU/SAL) (BEC/FOR HR 0.59, 95% CI 0.43-0.81; BUD/FOR HR 0.68, 95% CI 0.50-0.93). BEC/FOR resulted in lower risks of hospitalized respiratory infection (HR 0.48, 95% 0.26-0.86) and all-cause hospitalization (HR 0.55, 95% 0.37-0.80) compared to FLU/SAL. CONCLUSION: Our findings provide important evidence on the effectiveness and safety of ICS/LABA FDC compared with LAMA for bronchiectasis. BEC/FOR and BUD/FOR were associated with better outcomes than FLU/SAL.

RESUMEN

OBJECTIVE: Chronic heart failure (CHF) is a condition that is daily confronted by clinicians in a variety of medical specialties, where physicians routinely seek optimum pharmacotherapy for their outpatients with CHF. We conducted a population- based study on pharmacotherapy for outpatients with CHF in Taiwan from 2000 to 2010, which focused on drug prescription patterns of different physician specialties. MATERIALS AND METHODS: We retrieved records from the National Health Insurance Research Database of patient ambulatory visits with diagnosed chronic heart failure, when cardiovascular drugs were prescribed. For purposes of this study, anti-chronic heart failure drugs were separated into categories: mortality reducing agents (angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, ß-blockers, spironolactone, hydralazine plus nitrates) and symptom-relieving agents (digoxin, diuretics). Thereafter, the trends of prescription patterns related to different physician specialties were analyzed. RESULTS: From 2000 to 2010, the prescription rate of any mortality-reducing agent for CHF outpatients rose from 61.5% to 76.3% while the concomitant rate for digoxin decreased from 47.3% to 45.4%. Compared to internists and family physicians, cardiologists not only prescribed far more mortality-reducing agents from 2000 to 2010 (53.9 - 72.7%, 54.1 - 64.3%, 74.7 - 84.4%, respectively), but also prescribed two or three mortality-reducing drugs. CONCLUSION: There was a significant improvement of optimal pharmacotherapy for chronic heart failure in Taiwan. We observed that cardiologists were more aggressive than non-cardiologists when deciding whether to prescribe mortality-reducing drugs for heart failure management. However, those factors which influence the prescription patterns of internists and family physicians for their patients with CHF still require additional research.

RESUMEN

BACKGROUND: To estimate the extents of dosing variability in prescriptions of acetaminophen to children among pediatricians, family physicians and otolaryngologists. METHODS: The acetaminophen prescriptions in the systematic sampling datasets from the National Health Insurance Research Database in Taiwan were analyzed. The distribution of dosages was measured and expressed in terms of coefficient of variation (CV). The analyses were stratified by patient's age, prescriber's specialty and preparation form. RESULTS: From 13,868 prescribed items of acetaminophen in 2009, liquids accounted only for 11.1% (n = 1544). More than half (56.9%) of liquids were prescribed by pediatricians. The median dose (83.3 mg, n = 1683) of acetaminophen prescriptions in infants is around half of that in preschool children (166.7 mg, n = 3921), one-third in children (250.0 mg, n = 4926) and one-sixth in adolescents (500.0 mg, n = 3338). In infants, the prescriptions by pediatricians had the highest CV (86.7%), followed by family physicians (82.3%) and otolaryngologists (70.3%). The patterns were similar in preschool children and children, but the difference of CV among specialties narrowed down with the patient's age. CONCLUSIONS: In acetaminophen prescriptions to children, pediatricians had a wider variability of dosages and a higher ratio of liquid preparations than family physicians and otolaryngologists. Further investigations can be undertaken to estimate the accuracy of dosing variability as an indicator of prescribing quality. Besides, child-suitable drug preparations should be promoted to ensure patient safety.

RESUMEN

BACKGROUND: Medication adherence is critical for patient treatment. This study involved evaluating how implementing Short Message Service (SMS) reminders affected patient medication adherence and related factors. METHODS: We used a structured questionnaire to survey outpatients at three medical centers. Patients aged 20 years and older who were prescribed more than 7 days of a prescription medication were randomized into SMS intervention or control groups. The intervention group received daily messages reminding them of aspects regarding taking their medication; the control group received no messages. A phone follow-up was performed to assess outcomes after 8 days. Data were collected from 763 participants in the intervention group and 435 participants in the control group. RESULTS: After participants in the intervention group received SMS reminders to take medication or those in the control group received no messages, incidences of delayed doses were decreased by 46.4 and 78.8% for those in the control and intervention groups, respectively. The rate of missed doses was decreased by 90.1% for participants in the intervention group and 61.1% for those in the control group. We applied logistic regression analysis and determined that participants in the intervention group had a 3.2-fold higher probability of having a decrease in delayed doses compared with participants in the control group. Participants in the intervention group also showed a 2.2-fold higher probability of having a decrease in missed doses compared with participants in the control group. CONCLUSIONS: Use of SMS significantly affected the rates of taking medicine on schedule. Therefore, daily SMS could be useful for reminding patients to take their medicine on schedule.

RESUMEN

BACKGROUND: Little is known about how middle-aged and older women with intellectual disability (ID) cope with life transitions such as perimenopause and postmenopause. METHOD: A mixed methods approach was employed to explore the attitudes toward and experiences of menopause among women with ID and their family carers in one city in Taiwan. RESULTS: A survey found that how the carers perceived the level of menopausal symptoms in their female family members with ID was affected by their attitudes toward menopause; and carer age and education were significant factors associated with carer menopausal attitudes. The results of in-depth interviews indicated the carers' gender, age, kinships with the women with ID, and the carers' own menopausal experiences were related to how the carers felt about the menopausal transition of the women with ID. CONCLUSIONS: Both quantitative and qualitative findings show that little attention has been paid to either the menopausal transition experiences or the wellbeing of women with ID.

RESUMEN

BACKGROUND: This study explored the experiences of working mothers with an adult child with intellectual disabilities to understand how they reconcile paid work and care responsibilities. METHODS: Fifteen working mothers in Taiwan with an adult child with intellectual disabilities were interviewed, and an interpretative phenomenological approach was adopted for data collection and analysis. RESULTS: All included mothers prioritized their caregiving role over paid work. The strategies used by these mothers to make paid work fit with caregiving included having strong social networks and informal support for their care work, use of formal services, personal religious beliefs and positive attitudes towards care, as well as having flexible working hours due to self-employment, good relations with employers, working positions and work locations. CONCLUSIONS: Formal systems, which include both welfare and labour policies, need to be responsive to and involved in supporting these working mothers, especially those who lack good personal networks.
