Hecker M, Frahm N, Zettl UK. Update and Application of a Deep Learning Model for the Prediction of Interactions between Drugs Used by Patients with Multiple Sclerosis. Pharmaceutics 2023; 16:3. [PMID: 38276481 PMCID: PMC10819178 DOI: 10.3390/pharmaceutics16010003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 12/12/2023] [Accepted: 12/14/2023] [Indexed: 01/27/2024] Open
Abstract
Patients with multiple sclerosis (MS) often take multiple drugs at the same time to modify the course of disease, alleviate neurological symptoms and manage co-existing conditions. A major consequence for a patient taking different medications is a higher risk of treatment failure and side effects. This is because a drug may alter the pharmacokinetic and/or pharmacodynamic properties of another drug, which is referred to as drug-drug interaction (DDI). We aimed to predict interactions of drugs that are used by patients with MS based on a deep neural network (DNN) using structural information as input. We further aimed to identify potential drug-food interactions (DFIs), which can affect drug efficacy and patient safety as well. We used DeepDDI, a multi-label classification model of specific DDI types, to predict changes in pharmacological effects and/or the risk of adverse drug events when two or more drugs are taken together. The original model with ~34 million trainable parameters was updated using >1 million DDIs recorded in the DrugBank database. Structure data of food components were obtained from the FooDB database. The medication plans of patients with MS (n = 627) were then searched for pairwise interactions between drug and food compounds. The updated DeepDDI model achieved accuracies of 92.2% and 92.1% on the validation and testing sets, respectively. The patients with MS used 312 different small molecule drugs as prescription or over-the-counter medications. In the medication plans, we identified 3748 DDIs in DrugBank and 13,365 DDIs using DeepDDI. At least one DDI was found for most patients (n = 509 or 81.2% based on the DNN model). The predictions revealed that many patients would be at increased risk of bleeding and bradycardic complications due to a potential DDI if they were to start a disease-modifying therapy with cladribine (n = 242 or 38.6%) and fingolimod (n = 279 or 44.5%), respectively. We also obtained numerous potential interactions for Bruton's tyrosine kinase inhibitors that are in clinical development for MS, such as evobrutinib (n = 434 DDIs). Food sources most often related to DFIs were corn (n = 5456 DFIs) and cow's milk (n = 4243 DFIs). We demonstrate that deep learning techniques can exploit chemical structure similarity to accurately predict DDIs and DFIs in patients with MS. Our study specifies drug pairs that potentially interact, suggests mechanisms causing adverse drug effects, informs about whether interacting drugs can be replaced with alternative drugs to avoid critical DDIs and provides dietary recommendations for MS patients who are taking certain drugs.

Abstract
The coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), epidemic poses a major global public health threat with more than one million daily new infections and hundreds of deaths. To combat this global pandemic, efficient prevention and management strategies are urgently needed. Together with the main characteristics of COVID-19, impaired coagulation with dysfunctions of the immune response in COVID-19 pathophysiology causes high mortality and morbidity. From recent clinical observations, increased expression of specific types of estrogen appears to protect patients from SARS-CoV-2 infection, thereby, reducing mortality. COVID-19 severity is less common in women than in men, particularly in menopausal women. Furthermore, estrogen levels are negatively correlated with COVID-19 severity and mortality. These findings suggest that estrogen plays a protective role in the pathophysiology of COVID-19. In this review, we discuss the potential roles of estrogen in blocking the SARS-CoV-2 from invading alveolar cells and replicating, and summarize the potential mechanisms of anti-inflammation, immune modulation, reactive oxygen species resistance, anti-thrombosis, vascular dilation, and vascular endothelium protection. Finally, the potential therapeutic effects of estrogen against COVID-19 are reviewed. This review provides insights into the role of estrogen and its use as a potential strategy to reduce the mortality associated with COVID-19, and possibly other viral infections and discusses the possible challenges and pertinent questions.

Abstract
There is strong evidence that sex chromosomes and sex hormones influence blood pressure (BP) regulation, distribution of cardiovascular (CV) risk factors and co-morbidities differentially in females and males with essential arterial hypertension. The risk for CV disease increases at a lower BP level in females than in males, suggesting that sex-specific thresholds for diagnosis of hypertension may be reasonable. However, due to paucity of data, in particularly from specifically designed clinical trials, it is not yet known whether hypertension should be differently managed in females and males, including treatment goals and choice and dosages of antihypertensive drugs. Accordingly, this consensus document was conceived to provide a comprehensive overview of current knowledge on sex differences in essential hypertension including BP development over the life course, development of hypertension, pathophysiologic mechanisms regulating BP, interaction of BP with CV risk factors and co-morbidities, hypertension-mediated organ damage in the heart and the arteries, impact on incident CV disease, and differences in the effect of antihypertensive treatment. The consensus document also highlights areas where focused research is needed to advance sex-specific prevention and management of hypertension.

Abstract
In the modern drug discovery pipeline, identification of novel drug targets is a critical step. Despite rapid progress in developing biomedical techniques, it is still a great challenge to find promising new targets from the ample space of human genes. This fact is partially responsible for the situation of "more investments, fewer drugs" in the pharmaceutical industry. A series of recent researches revealed that successfully targeted genes share some common evolutionary and genetic features, which means that the knowledge accumulated in modern evolutionary biology and genetics is very helpful to identify potential drug targets and to find new drugs as well. In this article, we comprehensively summarize the links between human drug targets and genetic diseases and their evolutionary origins, with an attempt to introduce these novel concepts and their medical implications to the biomedical community.

Abstract
RATIONALE The processing of emotional information is affected by menstrual cycle phase and by the use of oral contraceptives (OCs). The stress hormone cortisol is known to affect emotional information processing via the limbic mineralocorticoid receptor (MR). OBJECTIVES We investigated in an exploratory study whether the MR-genotype moderates the effect of both OC-use and menstrual cycle phase on emotional cognition. METHODS Healthy premenopausal volunteers (n=93) of West-European descent completed a battery of emotional cognition tests. Forty-nine participants were OC users and 44 naturally cycling, 21 of whom were tested in the early follicular (EF) and 23 in the mid-luteal (ML) phase of the menstrual cycle. RESULTS In MR-haplotype 1/3 carriers, ML women gambled more than EF women when their risk to lose was relatively small. In MR-haplotype 2, ML women gambled more than EF women, regardless of their odds of winning. OC-users with MR-haplotype 1/3 recognised fewer facial expressions than ML women with MR-haplotype 1/3. CONCLUSION MR-haplotype 1/3 carriers may be more sensitive to the influence of their female hormonal status. MR-haplotype 2 carriers showed more risky decision-making. As this may reflect optimistic expectations, this finding may support previous observations in female carriers of MR-haplotype 2 in a naturalistic cohort study.

Abstract
After a worldwide breakdown of hormone therapy [HT] following the publications of the Women's Health Initiative trial and Million Women's Study in 2002-2003, there is now a trend to turn attention again to HT and to explore particular progestogens, which have been discredited with respect to their side effects. The progestogens to be considered should control undue proliferation of the endometrium and should not interfere negatively with the positive effects of estradiol, regarding carbohydrate and lipid metabolism as well as hemostasis. In the present review, three "newer progestogens" are scrutinized regarding their various actions, in combination with estradiol; the progestogens include dienogest, drospirenone and nomegestrol acetate. This article is part of a special issue entitled Menopause.

Abstract
The blockade of mineralocorticoid receptors (MR) has been shown to be an invaluable therapy in heart failure and hypertension. To date, only two steroidal antimineralocorticoids, spironolactone (and its active metabolite canrenone) and eplerenone, have been approved, whereas novel non-steroidal compounds are in preclinical and early development. The careful investigation of the efficacy and tolerance of spironolactone in essential hypertension initially supported the idea that a more selective second generation of MR antagonists is desired for chronic treatment of cardiovascular diseases. More than 40 years went by between the approval of the first MR antagonist spironolactone and the market introduction of its sole successor, eplerenone. The molecular pharmacology of MR antagonists may be addressed at different levels. Available preclinical and clinical data of the two approved steroidal antimineralocorticoids allow a good comparison of potency and selectivity of MR antagonists and their pharmacokinetic properties. The search for novel generations of MR antagonists with the ultimate goal of a more tissue selective mode of action may require novel compounds that are differentiated with respect to the binding mode to the MR. Other factors that may contribute to tissue selectivity as e.g. the physicochemical properties of a drug and how they influence the resulting pharmacology in the context of tissue selective co-factor expression are even less well understood. In the following we will review these aspects and demonstrate that the molecular pharmacology of current MR antagonists is on the one hand far from well understood and, on the other hand, still offers room for improvements.

Abstract
Oral contraceptives and postmenopausal hormone therapy may induce hypertension through multiple mechanisms, including sodium and volume retention. Numerous studies have shown significant increases in blood pressure (BP) with the chronic administration of oral contraceptives as well as reversibility with discontinuation. The effects of different classes of oral contraceptive agents and hormonal replacement therapy on BP and associated effects on other cardiovascular risk factors are covered in this article. Novel hormonal replacement therapy that lowers BP is also discussed.

Abstract
Despite the existence of established, effective therapies for hypertension, new methods of blood pressure and cardiovascular risk reduction are still needed. Novel approaches are targeted towards treating resistant hypertension, improving blood-pressure control, and achieving further risk reduction beyond blood-pressure lowering. Modulation of the renin-angiotensin-aldosterone system (RAAS) provides the rationale for current antihypertensive therapies, including the relatively new agents eplerenone and aliskiren. Novel targets for antihypertensive therapy are also likely to be RAAS-related. The stimulation of angiotensin II type 2 receptors, or supplementation with renalase, could counteract the effects of angiotensin II type 1 receptor stimulation or catecholamine release. Combined angiotensin-converting-enzyme and neutral endopeptidase blockade decreases blood pressure, but is associated with a high incidence of angioedema. Aldosterone synthase inhibitors might improve tolerability in aldosterone antagonism. A (pro)renin-receptor blocker could prevent the deleterious angiotensin-independent actions of renin that are not inhibited by aliskiren. Finally, new minimally invasive surgical procedures have revived the concept of renal denervation, and could be a therapeutic option for patients with resistant hypertension. All of these strategies are exciting prospects, but which of them will prove valuable in clinical setting remains to be discovered.

Abstract
OBJECTIVE We sought to verify if an oral contraceptive (OC) containing drospirenone affects the cardiovascular risk of patients with polycystic ovary syndrome (PCOS). STUDY DESIGN A total of 28 women with PCOS (16 lean [group A] and 12 overweight [group B]) were assessed at baseline and after 6 months therapy with an OC. Leptin, homocysteine, endothelin-1, and flow-mediated dilatation of brachial artery were measured. RESULTS The brachial artery diameter and the pulsatility index, after the reactive hyperemia, did not change in group A; it improved significantly in group B after 6 months of treatment. At baseline and after therapy the plasma levels of homocysteine and endothelin-1 did not differ among the groups. Leptin was significantly lower at baseline in group A compared to group B. CONCLUSION The OC containing drospirenone does not seem to affect the surrogate markers of cardiovascular risk in lean patients with PCOS.

Abstract
Since the publication of the Women's Health Initiative (WHI) study followed by the results of the Million Women Study (MWS), the role of hormonal therapy in postmenopausal women has been further challenged. The risks attributed to hormone therapy have been overestimated and the data has been wrongly extrapolated to the whole class of therapies. The trends in postmenopausal hormonal therapy seem now to favor the non-oral delivery routes for both the estrogen and the progestin for women with an intact uterus, based on the assumption that a lesser stimulation of the liver proteins and a neutral metabolic profile would be more favorable in terms of cardiovascular and venous risk. The combination of non-oral administration of estradiol and local delivery of progesterone or a progestin such as levonorgestrel by means of gels, sprays, vaginal rings or intrauterine systems would represent new methods of replacement therapy for the menopausal woman, improving compliance and minimizing the risks of hormone replacement. Several of these systems are either available or in development. Long-term studies on the risk/benefit of various non-oral formulations are certainly warranted.

Abstract
During menopause vasomotor symptoms are one of the main complaints about which women seek medical advice. For symptom control, several therapies have been used, among which hormone therapy has produced good results. One of these is estrogen monotherapy, which unfortunately may induce endometrial hyperplasia in women with an intact uterus. A progestin must be added to avoid this risk. Progestins may induce several secondary effects such as breast tenderness, hirsutism, edema and unfavorable lipid profile modifications. Recently a new progestin called drospirenone has been synthesized and used in combination with estradiol for the treatment of postmenopausal women. This progestin is derived from spironolactone, and lacks estrogenic, androgenic and glucocorticoid activities. Several studies have evaluated safety, efficacy and patient tolerability, and have shown a good profile in all these parameters. All studies agree that the combination of estradiol 1 mg plus drospirenone 2 mg is a good choice for postmenopausal women with vasomotor symptoms.
