Abstract
Since angiotensin-converting enzyme (ACE) inhibitors and calcium antagonists have complimentary mechanisms of action, enalapril, an ACE inhibitor, is used in combination with felodipine, a vascular selective dihydropyridine calcium antagonist, for the treatment of hypertension. The present study was designed to investigate the possible drug-drug interaction between these two agents in Chinese healthy subjects. A randomized, open-label, multiple-dose, 3-treatment, 3-period, 6-sequence cross-over study enrolling 12 healthy subjects (six male and six female subjects) was performed. Plasma pharmacokinetic studies were performed after 5 mg of enalapril and 5 mg of felodipine were administered alone or concomitantly twice per day for six days, and once in the morning of day seven. All 12 healthy subjects (mean [SD] age, 24.3 [2.8] years; body weight, 57.3 [5.7] kg; height, 163.2 [5.2] cm) completed all scheduled pharmacokinetic studies. Geometric mean ratios (with 90% CIs) of AUCτ,ss and Cmax,ss for enalapril administered concomitantly with felodipine vs. enalapril administered alone were 1.025 (0.80-1.25) and 1.065 (0.70-1.43), respectively. Geometric mean ratios (with 90% CIs) of AUCτ,ss and Cmax,ss for felodipine administered concomitantly with enalapril vs. felodipine administered alone were 1.14 (0.97-1.31) and 0.80 (0.65-0.95), respectively. There were no severe or serious drug-related adverse events observed during the study. Our results revealed that the co-administration of enalapril and felodipine affected the pharmacokinetics of felodipine, but not that of enalapril. Although the difference in PK parameters was statistically significant, its clinical significance may be limited, considering safety profile observed in the present study.

Citric Acid Metabolism in Resistant Hypertension: Underlying Mechanisms and Metabolic Prediction of Treatment Response.

Hypertension. 2017 Nov;70(5):1049-1056

Abstract
Resistant hypertension (RH) affects 9% to 12% of hypertensive adults. Prolonged exposure to suboptimal blood pressure control results in end-organ damage and cardiovascular risk. Spironolactone is the most effective drug for treatment, but not all patients respond and side effects are not negligible. Little is known on the mechanisms responsible for RH. We aimed to identify metabolic alterations in urine. In addition, a potential capacity of metabolites to predict response to spironolactone was investigated. Urine was collected from 29 patients with RH and from a group of 13 subjects with pseudo-RH. For patients, samples were collected before and after spironolactone administration and were classified in responders (n=19) and nonresponders (n=10). Nuclear magnetic resonance was applied to identify altered metabolites and pathways. Metabolites were confirmed by liquid chromatography-mass spectrometry. Citric acid cycle was the pathway most significantly altered (P<0.0001). Metabolic concentrations were quantified and ranged from ng/mL malate to μg/mL citrate. Citrate and oxaloacetate increased in RH versus pseudoresistant. Together with α-ketoglutarate and malate, they were able to discriminate between responders and nonresponders, being the 4 metabolites increased in nonresponders. Combined as a prediction panel, they showed receiver operating characteristiccurve with area under the curve of 0.96. We show that citric acid cycle and deregulation of reactive oxygen species homeostasis control continue its activation after hypertension was developed. A metabolic panel showing alteration before spironolactone treatment and predicting future response of patients is shown. These molecular indicators will contribute optimizing the rate of control of RH patients with spironolactone.

Regorafenib induced severe toxic hepatitis: characterization and discussion.

Liver Int. 2016 Nov;36(11):1590-1594

Abstract
BACKGROUND: Regorafenib is the first small-molecule multikinase inhibitor which showed survival benefits in pretreated metastatic colorectal cancer (mCRC) patients. Besides classical adverse events of this drug class, hepatotoxicity has been described as a frequent side effect.
MATERIAL AND METHODS: Patients with refractory mCRC treated with regorafenib in our institution were reviewed. Severe treatment-related liver toxicity was investigated. Clinical history, liver histology and genetic assessment (sequence analysis) of cytochrome P3A4 (CYP3A4) and uridine diphosphate-glucuronosyltransferase 1A9 (UGT1A9) involved in regorafenib metabolization were here reported for patients with severe hepatotoxicity.
RESULTS: Among the 93 reviewed patients, 3 presented severe and icteric toxic hepatitis which was fatal for 1 patient. Histopathological liver lesions were different depending on the onset of hepatotoxicity (acute or subacute): acinar zone 3 necrosis in case of acute symptoms, and portal tract inflammation with porto-central bridging and fibrosis in the delayed presentation. None of the patients had CYP3A4 gene mutations. Similar polymorphisms in UGT1A9 gene promoter region (UGT1A9 variant -118T9>10 [rs3832043]) were found in both patients who presented acute hepatitis. Moreover, it appears retrospectively that both of them already experienced significant toxicity under irinotecan-based chemotherapy.
CONCLUSION: This is the first report of severe hepatotoxicity with available liver histology and genetic assessment of enzymes involved in regorafenib metabolization. This report also reminds the importance of close liver tests monitoring during regorafenib treatment.

[Hepatotoxicity in healthy infants exposed to nevirapine during pregnancy].

Enferm Infecc Microbiol Clin. 2016 Jan;34(1):39-44

Authors: Iveli P, Noguera-Julian A, Soler-Palacín P, Martín-Nalda A, Rovira-Girabal N, Fortuny-Guasch C, Figueras-Nadal C

Abstract
BACKGROUND: The use of nevirapine in HIV-infected pregnant women is discouraged due to its potential to cause hepatotoxicity. There is limited information available on the toxicity in non-HIV infected newborn exposed to this drug during pregnancy. The aim of the study is to determine the extent of hepatotoxicity in the newborn exposed to nevirapine and HIV during pregnancy.
METHODS: A cross-sectional, observational, multicenter study was conducted on a cohort of healthy infants born to HIV-infected mothers, in whom the first determination of alanine aminotransferase (ALT), before 6weeks of age, was collected. Patients were allocated to 2groups according to exposure to nevirapine during pregnancy. Hepatotoxicity was rated according to the AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS).
RESULTS: This study included 160newborns from 159pregnancies (88exposed to nevirapine-based regimens and 71 exposed to protease inhibitors-based therapies). No cases of hepatotoxicity were observed according to the DAIDS Table for Grading. Two cases of ALT above normal values (2.8%; 95%CI: 0.3-9.8%) were observed in patients not exposed to nevirapine, and one case (1.1%; 95%CI: 0.0-6.1%) in the group exposed to nevirapine (P=.585).
CONCLUSION: The lack of differences between groups suggests that highly active antiretroviral treatment regimens including nevirapine administered during pregnancy do not involve a higher risk of liver disease compared to other treatment combinations.

Dietary Supplements, Isotretinoin, and Liver Toxicity in Adolescents: A Retrospective Case Series.

Pediatrics. 2017 Oct;140(4):

Authors: DeKlotz CMC, Roby KD, Friedlander SF

Abstract
Isotretinoin is the most effective acne therapy available, but has the potential for a number of adverse side effects, including transaminitis. The iPLEDGE isotretinoin program recommends avoiding some herbals and supplements due to potential side effects. However, little is known about the effects of protein supplements on the liver, particularly in patients taking isotretinoin. We designed a retrospective chart review to evaluate the symptoms, diagnosis, treatment, and outcome of patients on or preparing to take isotretinoin therapy who were concurrently ingesting protein or herbal supplementation and who developed transaminitis. In 100% (8/8) of cases, dietary supplementation was determined to be at least a possible cause of elevated liver transaminases. In 75% (6/8) of cases, dietary supplement appears to be the most likely cause at some point in their evaluation. Most of our patients' elevations in aspartate aminotransferase and/or alanine aminotransferase were likely caused by supplementation with protein, creatine, or herbal extracts, rather than prescribed isotretinoin or tetracycline antibiotics for acne. Hence, dietary supplementation may cause liver function abnormalities. As supplement usage appears common in teenagers, clinicians should consider counseling their patients to avoid these products, particularly when prescribing known hepatotoxic drugs.

Goldilocks' Determination of What New In Vivo Data are "Just Right" for Different Common Drug Development Scenarios, Part 1.

Birth Defects Res B Dev Reprod Toxicol. 2016 Aug;107(4-5):185-194

Authors: Bowman CJ, Chapin RE

Abstract
As alternative models and scientific advancements improve the ability to predict developmental toxicity, the challenge is how to best use this information to support safe use of pharmaceuticals in humans. While in vivo experimental data are often expected, there are other important considerations that drive the impact of developmental toxicity data to human risk assessment and product labeling. These considerations include three key elements: (1) the drug's likelihood of producing off-target toxicities, (2) risk tolerance of adverse effects based on indication and patient population, and (3) how much is known about the effects of modulating the target in pregnancy and developmental biology. For example, there is little impact or value of a study in pregnant monkeys to inform the risk assessment for a highly specific monoclonal antibody indicated for a life-threatening indication against a target known to be critical for pregnancy maintenance and fetal survival. In contrast, a small molecule to a novel biological target for a chronic lifestyle indication would warrant more safety data than simply in vitro studies and a literature review. Rather than accounting for innumerable theoretical possibilities surrounding each potential submission's profile, we consolidated most of the typical situations into eight possible scenarios across these three elements, and present a discussion of these scenarios here. We hope that this framework will facilitate a rational approach to determining what new information is required to inform developmental toxicity risk of pharmaceuticals in context of the specific needs of each program while reducing animal use where possible.

[Hypervitaminosis D due to a dietary supplement].

Ned Tijdschr Geneeskd. 2016;160:A9360

Authors: Zigenhorn M, Westerman EM, Rietveld AP

Abstract
In the Netherlands, over-the-counter dietary supplements are controlled by the NVWA (Netherlands Food and Consumer Product Safety Authority). Nevertheless, health problems may ensue from the use of these freely available supplements. We describe the case of a 39-year-old woman with a four-week history of headaches, nausea, reduced appetite and weight loss. Laboratory results showed severe hypercalcemia and impaired kidney function. An isolated increased vitamin D level was shown to be the cause. Although initial drug-taking history was negative, it appeared our patient had consumed a concentrated vitamin D supplement, supplied by a naturopath. The vitamin D concentration of the contents of this specific flacon proved to be 78 times higher than stated on the label. Consumers must be aware of the potential health risks posed by over-the-counter dietary supplements. We appeal to GPs, medical specialists and pharmacists to report these kinds of intoxications, allowing relevant authorities to subject the associated companies to adequate control measures.

The acute and long-term L-DOPA effects are independent from changes in the activity of dorsal raphe serotonergic neurons in 6-OHDA lesioned rats.

Br J Pharmacol. 2016 Jul;173(13):2135-46

Authors: Miguelez C, Navailles S, De Deurwaerdère P, Ugedo L

Abstract
BACKGROUND AND PURPOSE: L-DOPA is still the most efficacious pharmacological treatment for Parkinson's disease. However, in the majority of patients receiving long-term therapy with L-DOPA, its efficacy is compromised by motor complications, notably L-DOPA-induced dyskinesia. Evidence suggests that the serotonergic system is involved in the therapeutic and the side effects of L-DOPA. Here, we investigate if long-term L-DOPA treatment alters the activity of the dorsal raphe nucleus (DRN) and its responses to serotonergic drugs.
EXPERIMENTAL APPROACH: We measured the responses of serotonergic neurons to acute and chronic L-DOPA treatment using in vivo electrophysiological single unit-extracellular recordings in the 6-OHDA-lesion rat model of Parkinson's disease.
KEY RESULTS: The results showed that neither acute nor chronic L-DOPA administration (6 mg·kg(-1)  s.c.) altered the properties of serotonergic-like neurons. Furthermore, no correlation was found between the activity of these neurons and the magnitude of L-DOPA-induced dyskinesia. In dyskinetic rats, the inhibitory response induced by the 5-HT1A receptor agonist 8-OH-DPAT (0.0625-16 μg·kg(-1) , i.v.) was preserved. Nonetheless, L-DOPA impaired the ability of the serotonin reuptake inhibitor fluoxetine (0.125-8 mg·kg(-1) , i.v) to inhibit DRN neuron firing rate in dyskinetic animals.
CONCLUSIONS AND IMPLICATIONS: Although serotonergic neurons are involved in the dopaminergic effects of L-DOPA, we provide evidence that the effect of L-DOPA is not related to changes of the activity of DRN neurons. Rather, L-DOPA might reduce the efficacy of drugs that normally enhance the extracellular levels of serotonin.

Abstract
OBJECTIVE: To evaluate the effectiveness of Jian Pi Li Qi (JPLQ) decoction in improving quality of life of patients with hepatocellular carcinoma (HCC) following transcatheter arterial chemoembolization (TACE).
METHODS: A randomized, double-blind, placebo-controlled trial was conducted. A total of 150 patients with HCC were randomly assigned into 3 groups. Groups were designed as follows: neither herbal medicine nor placebo administration (group A), placebo treatment (group B), and JPLQ decoction treatment (group C). The measurement methods of the observed outcomes include MD Anderson Symptom Inventory-Gastrointestinal module, armpit temperature, and laboratory tests.
RESULTS: Among the 140 patients studied, the 12 symptoms rated as most severe, which characterize postembolization syndrome (PES), were fever, pain, fatigue, nausea, disturbed sleep, distress, lack of appetite, drowsiness, dry mouth, vomiting, constipation, and feeling bloated. All these increased significantly (all P < .05) after TACE; 7 symptoms, including fever, pain, fatigue, lack of appetite, drowsiness, dry mouth, and constipation (all P < .05), were found to be relieved significantly by JPLQ. JPLQ also improved the liver function damage caused by TACE.
CONCLUSION: JPLQ decoction may be an effective modality to relieve PES and protect liver function in patients with HCC after TACE.

Curculigo orchioides Gaertn Effectively Ameliorates the Uro- and Nephrotoxicities Induced by Cyclophosphamide Administration in Experimental Animals.

Integr Cancer Ther. 2016 Jun;15(2):205-15

Authors: Murali VP, Kuttan G

Abstract
Background Curculigo orchioides Gaertn is an ancient medicinal plant (Family: Amaryllidaceae), well known for its immunomodulatory and rejuvenating effects. Cyclophosphamide (CPA) is an alkylating agent widely used for treating a variety of human malignancies, but associated with different toxicities too. Our previous reports regarding the hemoprotective and hepatoprotective effects of the plant against CPA toxicities provide the background for the present study, which is designed to analyze the ameliorative effect of the methanolic extract of C orchioides on the urotoxicity and nephrotoxicity induced by CPA. Methods CPA was administered to male Swiss albino mice at a single dose of 1.5 mmol/kg body weight to induce urotoxicity after 5 days of prophylactic treatment with C orchioides extract (20 mg/kg body weight). Mesna (2-mercaptoethanesulfonate) was used as a control drug. Serum, tissue, and urine levels of kidney function markers and antioxidant levels were checked along with the serum cytokine levels. Results The plant extract was found to be effective in ameliorating the urotoxic and nephrotoxic side effects of CPA. Upregulation of serum interferon-γ and interleukin-2 levels were observed with C orchioides treatment, which was decreased by CPA administration. Besides these, serum tumor necrosis factor-α level was also downregulated by C orchioides treatment. Conclusion Curculigo orchioides was found to be effective against the CPA-induced bladder and renal toxicities by its antioxidant capability and also by regulating the pro-inflammatory cytokine levels.

Efficacy and safety of intravenous laronidase for mucopolysaccharidosis type I: A systematic review and meta-analysis.

PLoS One. 2017;12(8):e0184065

Abstract
OBJECTIVE: To evaluate the efficacy and safety of IV laronidase for MPS I.
METHODS: A systematic literature review was performed by searching the ClinicalTrials.gov, MEDLINE/PubMed, EMBASE, LILACS, and Cochrane Library databases, limited to clinical trials published until December 31, 2016. The first inclusion criterion was being a randomized controlled trial (RCT). If < five RCTs were identified, open-label and nonrandomized trials, controlled or uncontrolled (quasi-experimental), including ≥ five patients, and evaluating relevant outcomes defined a priori, would also be included. For meta-analysis, primary inferences were based on random-effects models. Assessment of article quality was performed in accordance with the GRADE criteria. The Cochrane Risk of Bias tool was used to examine the risk of bias for RCTs.
RESULTS: The selection phase retrieved 632 articles. During the first phase of selection, 158 had the abstract or full text read for assessment of eligibility, of which nine (two RCTs) were included for qualitative synthesis. Four papers were included in the meta-analysis, which was performed for the following outcomes: occurrence of treatment-emergent or infusion-related adverse events (65%; 95%CI 53, 76), mild in most cases; development of IgG antibodies to laronidase (88%; 95%CI 67, 100); apnea-hypopnea index (not significant-NS), urinary glycosaminoglycans (GAGs) [mean change -65.5 μg/mg creatinine (95%CI -68.8, -62.3)], liver size [mean change -31.03% (95%CI -36.1, -25.9)], left ventricular mass index (LVMI) [mean change -1.8 (95%CI -2.32, -0.25)], and distance covered in the 6-minute walk test (NS). Among the outcomes not included in meta-analysis, we found evidence for benefit of laronidase only on shoulder flexion.
CONCLUSIONS: Our findings suggest that IV laronidase effectively reduces urinary GAGs excretion, hepatomegaly and LVMI, and can improve shoulder flexion in MPS I patients. Laronidase appears to be safe in the studied population.

Efficacy and safety of fumaric acid esters in combination with phototherapy in patients with moderate-to-severe plaque psoriasis (FAST).

J Dtsch Dermatol Ges. 2017 Feb;15(2):180-186

Authors: Weisenseel P, Reich K, Griemberg W, Merten K, Gröschel C, Gomez NN, Taipale K, Bräu B, Zschocke I

Abstract
BACKGROUND: While treatment of patients with moderate-to-severe psoriasis using a combination of fumaric acid esters (FAE, Fumaderm(®) ) and phototherapy (UV) is common practice, there have been hardly any studies investigating this regimen. Available information is limited to data from a small pilot study. The objective of the present study was to evaluate FAE/UV combination therapy in a larger patient cohort with moderate-to-severe psoriasis.
PATIENTS AND METHODS: In this prospective noninterventional multicenter study, data from patients treated with FAE/UV combination therapy was assessed with regard to efficacy (PGA' PASI, DLQI, EQ-5D), safety, and dosage over a twelve-month period. The findings were subsequently compared to data from a previous retrospective study on FAE monotherapy.
RESULTS: Data from 363 patients was included in the analysis. Efficacy measures improved substantially on combination therapy. Compared to FAE monotherapy, FAE/UV therapy led to a faster clinical response, however, there was no difference in efficacy after 12 months. Neither the duration nor the type of phototherapy had an impact on efficacy. In general, combination therapy was well tolerated. Seven percent of patients experienced adverse events.
CONCLUSIONS: FAE/UV combination therapy is effective and well tolerated in patients with moderate-to-severe psoriasis. Such treatment may induce a faster therapeutic response, and appears to be useful, particularly in the first three months of FAE therapy.

Should tumour necrosis factor antagonist safety information be applied from patients with rheumatoid arthritis to psoriasis? Rates of serious adverse events in the prospective rheumatoid arthritis BIOBADASER and psoriasis BIOBADADERM cohorts.

Br J Dermatol. 2017 Mar;176(3):643-649

Authors: García-Doval I, Hernández MV, Vanaclocha F, Sellas A, de la Cueva P, Montero D, BIOBADADERM and BIOBADASER study groups

Abstract
BACKGROUND: Information on the safety of tumour necrosis factor (TNF) antagonists frequently arises from their use in rheumatic diseases, their first approved indications, and is later applied to psoriasis. Whether the risk of biological therapy is similar in psoriasis and rheumatoid arthritis has been considered a priority research question.
OBJECTIVES: To compare the safety profile of anti-TNF drugs in patients with rheumatoid arthritis and psoriasis.
METHODS: We compared two prospective safety cohorts of patients with rheumatoid arthritis and psoriasis that share methods (BIOBADASER and BIOBADADERM).
RESULTS: There were 1248 serious or mortal adverse events in 16 230 person-years of follow-up in the rheumatoid arthritis cohort (3171 patients), and 124 in the 2760 person-years of follow-up of the psoriasis cohort (946 patients). Serious and mortal adverse events were less common in patients with psoriasis than in rheumatoid arthritis (incidence rate ratio of serious adverse events in psoriasis/rheumatoid arthritis: 0·6, 95% confidence interval 0·5-0·7). This risk remained after adjustment for sex, age, treatment, disease, hypertension, diabetes, hypercholesterolaemia and simultaneous therapy with methotrexate (hazard ratio 0·54, 95% confidence interval 0·47-0·61), and after excluding patients receiving corticosteroids. Patients with rheumatoid arthritis showed a higher rate of infections, cardiac disorders, respiratory disorders and infusion-related reactions, whereas patients with psoriasis had more skin and subcutaneous tissue disorders and hepatobiliary disorders.
CONCLUSIONS: Patients with rheumatoid arthritis clinical practice have almost double the risk of serious adverse events compared with patients with psoriasis, with a different pattern of adverse events. Safety data from rheumatoid arthritis should not be fully extrapolated to psoriasis. These differences are likely to apply to other immune-mediated inflammatory diseases.
