Introduction Complex or co-existing diseases are commonly treated using drug combinations by taking advantage of the synergistic effects caused by drug–drug interactions (DDIs). 1 However, unexpected DDIs also increase the risk of triggering adverse side effects or even serious toxicity. 2 With the increasing need for multi-drug treatments, the identification of unexpected DDIs becomes increasingly crucial. Traditionally, the detection of DDIs is performed through extensive biological or pharmacological assays. However, this process is time-consuming and labor-intensive, because a great number of combinations of drugs should be considered for experiments. As a result, computational methods can be used as a low-cost, yet effective alternative to predict potential DDIs by identifying patterns from known DDIs.

The following continuous covariates were included in the analysis: age, weight, height, body mass index (BMI), lean body mass (LBM), albumin, ALAT (SGPT), ASAT (SGOT), bilirubin and creatinine clearance. The following categorical covariates were included: sex, race, ethnicity (Hispanic or non-Hispanic), region (EU, USA or Japan) and inferred metabolic status for CYP2C9, CYP2C19 and CYP2D6. Each categorical covariate had to include at least 10 subjects; otherwise, the covariate was recategorised (if more than two categories) or omitted from the analysis.

Nucleoside reverse transcriptase inhibitors (NRTIs), including zidovudine (AZT), stavudine (d4T), didanosine (ddI), zalcitabine (ddC) and lamivudine (3TC), are used in the treatment of human immunodeficiency virus (HIV) infections. In combination with HIV protease inhibitors, NRTIs afford outstanding benefits in terms of HIV-induced morbidity and mortality ( 11). However, NRTIs can induce side effects of differing severity and frequency ( 6, 12, 26). Liver failure, lactic acidosis, or pancreatitis may be severe and sometimes fatal, but these occur in only a few patients ( 7, 13, 17, 48). Lipodystrophy and hyperlactatemia are less severe but much more frequent ( 14, 35). Z. Wang, J. Zhang, J. Feng and Z.

The cold start scenarios provide a realistic and more challenging evaluation scheme for the models. In the cold start scenarios, we randomly held 20% DDI tuples as the test set following the criterion described above. Other experimental settings are the same as those in the warm start scenario. We only considered the cold start scenarios in the DrugBank dataset, because the TWOSIDES dataset contains some false positives ( i.e., drug pairs included in the TWOSIDES do not interact) that would cause unreliable assessments for the models in the cold start scenarios. 20 We applied a weight decay of 5 × 10 −3 for all methods, because the models are easy to overfit to the drugs on which the model is trained in the cold start scenarios. 28Y.

Nos países e regiões lusófonos [ editar | editar código-fonte ] Angola [ editar | editar código-fonte ] There is no difference between DDI numbers (Direct-Dial-In) and DIDs (Direct Inward Dialling). DDI is the term used most often in Europe, whereas DID is used more widely in the US and other countries outside of Europe. How do DDIs work? Weng Y-A, Deng C-Y, Pu C.

All body size measures, except BMI, were strongly correlated with the central volume of distribution, although only height remained in the final model. Weight, LBM and height are all heavily correlated, especially for subjects participating in clinical pharmacology studies with narrow inclusion ranges; hence, inclusion of the most significant of them in the model often excludes the other ones. The small effect of height, as a measure of body size, on the simulated vortioxetine exposure (±5% for tall/short subjects compared to average height) is not considered of clinical relevance.

DDI stands for "Direct-Dial-In", and these numbers enable callers to reach a specific extension without speaking to a switchboard or using an automated menu system. Cold start for a pair of drugs (new ↔ new) is also a cold start scenario where both drugs in a drug pair in the test set are inaccessible in the training set.

Even the most active treatment (AZT) left 59% of residual mtDNA in the liver (Table ​ (Table2). 2). Since mtDNA encodes some of the polypeptides of complexes I, III, IV, and V of the respiratory chain, severe mtDNA depletion can decrease the activity of these complexes ( 5, 32). However, mtDNA must be severely depleted (to less than 20 to 30% of residual mtDNA) to impair mitochondrial respiration ( 24, 25). As expected, we found that complex I and complex IV activities were unchanged in the liver homogenates of mice treated for 2 weeks with ddI (66 mg/kg/day) or d4T (100 mg/kg/day) (results not shown), despite a ca. 30% decrease in hepatic mtDNA with both treatments (Table ​ (Table2) 2) ( 33). Unimpaired mitochondrial respiration likely explains why plasma lactate and plasma pyruvate were unchanged by the various NRTI treatments in the present study (see Results). Altogether, these results indicate that therapeutic doses of NRTIs do not impair mitochondrial function in mice after 2 weeks of treatment. Since NRTIs were administered for only 2 weeks, a greater effect on mtDNA after longer times of administration is not excluded.
