Chronic kidney disease in America, Africa, and Asia: Overview of treatment cost and options.

Chronic kidney disease (CKD) is one of the non-infectious diseases that threaten patients' lives on a daily basis. Its prevalence is high, but under-reported by patients and those living with the disease, as it is silent and asymptomatic in the early stages. Kidney disease increases the risk of heart and vascular disease. These problems can manifest themselves slowly, over a long period of time. Early detection and treatment can often prevent chronic kidney disease from worsening. As kidney disease progresses, it can lead to kidney failure, requiring dialysis or a kidney transplant to stay alive. In this narrative review, we will mainly discuss different treatment option costs in different countries and how much they cost healthcare systems in countries in three different continents.

Platelets Can Associate with SARS-Cov-2 RNA and Are Hyperactivated in COVID-19.

Rationale: In addition to the overwhelming lung inflammation that prevails in COVID-19, hypercoagulation and thrombosis contribute to the lethality of subjects infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Platelets are chiefly implicated in thrombosis. Moreover, they can interact with viruses and are an important source of inflammatory mediators. While a lower platelet count is associated with severity and mortality, little is known about platelet function during COVID-19. Objective: To evaluate the contribution of platelets to inflammation and thrombosis in COVID-19 patients. Methods and Results: Blood was collected from 115 consecutive COVID-19 patients presenting non-severe (n=71) and severe (n=44) respiratory symptoms. We document the presence of SARS-CoV-2 RNA associated with platelets of COVID-19 patients. Exhaustive assessment of cytokines in plasma and in platelets revealed the modulation of platelet-associated cytokine levels in both non-severe and severe COVID-19 patients, pointing to a direct contribution of platelets to the plasmatic cytokine load. Moreover, we demonstrate that platelets release their alpha- and dense-granule contents in both non-severe and severe forms of COVID-19. In comparison to concentrations measured in healthy volunteers, phosphatidylserine-exposing platelet extracellular vesicles were increased in non-severe, but not in severe cases of COVID-19. Levels of D-dimers, a marker of thrombosis, failed to correlate with any measured indicators of platelet activation. Functionally, platelets were hyperactivated in COVID-19 subjects presenting non-severe and severe symptoms, with aggregation occurring at suboptimal thrombin concentrations. Furthermore, platelets adhered more efficiently onto collagen-coated surfaces under flow conditions. Conclusions: Taken together, the data suggest that platelets are at the frontline of COVID-19 pathogenesis, as they release various sets of molecules through the different stages of the disease. Platelets may thus have the potential to contribute to the overwhelming thrombo-inflammation in COVID-19, and the inhibition of pathways related to platelet activation may improve the outcomes during COVID-19.

Trends in the consumption and cost of antiepileptics in Morocco between 2008 and 2018.

INTRODUCTION: Epilepsy is one of the most common chronic neurological diseases. In Morocco, it is the second most common reason for consulting a neurologist. Its prevalence was estimated in Casablanca in 1998 at 1.1%. This study was carried out with the aim of evaluating, on the one hand, the consumption of antiepileptics and, on the other hand, the impact of their generic drugs on the pharmaceutical market between 2008 and 2018 in Morocco. MATERIALS AND METHODS: We used sales data for antiepileptic drugs collected from the Moroccan subsidiary of IQVIA, a multinational healthcare data science company, and we converted them into a defined daily dose (DDD/1000 inhabitants). RESULTS: The consumption of antiepileptic drugs increased from 442 to 641 DDD/1000 inhabitants between 2008 and 2018, all molecules combined, recording a 45% increase in the period studied. From an economic point of view, the calculation of the average cost of DDD, all molecules combined, gives an average cost of 2.42 dollars/DDD in 2018 versus 3.53 dollars/DDD in 2008 (1 dirham = 0.11 dollar), which corresponds to a decrease of -30%. This is due mainly to the introduction of generic drugs. CONCLUSION: These results show that while the average cost of a DDD has decreased, the consumption of antiepileptics has increased in Morocco over the years. Several events that have marked the drug market in Morocco have contributed to this trend, including the arrival on the market of several new molecules indicated for the treatment of epilepsy, the decrease in drug prices in 2014 and the policy of promoting generic drugs.

Monoclonal Antibodies Application in Lateral Flow Immunochromatographic Assays for Drugs of Abuse Detection.

Lateral flow assays (lateral flow immunoassays and nucleic acid lateral flow assays) have experienced a great boom in a wide variety of early diagnostic and screening applications. As opposed to conventional examinations (High Performance Liquid Chromatography, Polymerase Chain Reaction, Gas chromatography-Mass Spectrometry, etc.), they obtain the results of a sample's analysis within a short period. In resource-limited areas, these tests must be simple, reliable, and inexpensive. In this review, we outline the production process of antibodies against drugs of abuse (such as heroin, amphetamine, benzodiazepines, cannabis, etc.), used in lateral flow immunoassays as revelation or detection molecules, with a focus on the components, the principles, the formats, and the mechanisms of reaction of these assays. Further, we report the monoclonal antibody advantages over the polyclonal ones used against drugs of abuse. The perspective on aptamer use for lateral flow assay development was also discussed as a possible alternative to antibodies in view of improving the limit of detection, sensitivity, and specificity of lateral flow assays.

Incidence of adverse reactions caused by first-line anti-tuberculosis drugs and treatment outcome of pulmonary tuberculosis patients in Morocco.

PURPOSE: The treatment of tuberculosis is associated with a high incidence of adverse reactions with different degrees of severity. The aim of this study was to determine the incidence of adverse reactions caused by first-line anti-tuberculosis drugs and to evaluate the treatment outcome of TB patients in a large region of Morocco. METHODS: It is a multi-centric observational cohort study conducted from January 01, 2014 to January 01, 2016. A questionnaire was established for data collection from clinical charts of TB patients. The study was carried out in all the 18 centers located in the Rabat-Salé-Kénitra region of Morocco where tuberculosis is treated. Adverse reactions are evaluated from the start of TB treatment until its end by a specialist clinician. The treatment outcomes are evaluated, and the definitions and classifications of these outcomes are defined according to World Health Organization guidelines. RESULTS: Among a total number of 2532 patients treated for TB, the average age is 37.3 ± 16.4 years, 10.0% of patients produced adverse reactions. 7.4% of adverse reactions are gastrointestinal, 3.7% are cutaneous, 2.0% are hepatic, 1.14% are articular, 1.07% are immunoallergic, 0.7% are neuropsychiatric, and 0.1% are ocular. The treatment outcome of TB patients is 79.1% rate for successful treatment and 15.6% for unsuccessful treatment. CONCLUSION: Adverse reactions caused by anti-TB drugs are frequent among patients with TB. These ADRs must be followed up by a closer monitoring during anti-TB treatment period. Treatment success outcome in our study is slightly lower than the success rate target of WHO of at least 85%.

Overview of recent developments of pyrazole derivatives as an anticancer agent in different cell line.

Pyrazole is a five-membered aromatic heterocyclic ring with two adjacent nitrogen atoms C3H3N2H.The presence of this nucleus in pharmacological agents of various therapeutic categories gifts a broad spectrum of biological activities and pharmaceuticals that contain pyrazole like celecoxib (anti-inflammatory), CDPPB (antipsychotic), Rimonabant (anti-obesity), Difenamizole, (Analgesic), Betazole (H2 receptor agonist), Fezolamide (Antidepressant), etc… The pharmacological potential of the pyrazole fraction is proved in many publication where they synthesized and evaluated pyrazoles against several biological agents. The aim of this article review is to survey recent works linking pyrazole structures to anticancer activities corresponding to 9 different type of cancer.

The displacement study of 99m Tc-DTPA-Human serum albumin binding in presence of furosemide and metformin by using equilibrium dialysis and molecular docking.

The 99m Tc-DTPA (Technetium99m diethylenetriaminepentaacetic acid), is a radiopharmaceutical used in renal scintigraphy. The human serum albumin (HSA) binding site(s) for the 99m Tc-DTPA have never been characterized. This study will cover in vitro the binding rates of 99m Tc-DTPA on HSA and the 99m Tc-DTPA competition interactions with two drugs having known human serum albumin binding sites. Furosemide (FUR) and metformin (MET) were added to 99m Tc-DTPA solution (weight ratios 1/1 vol:vol) followed by the quantification of 99m Tc-DTPA binding rates to HSA (40 g/L) using equilibrium dialysis and the qualification of this binding using Molecular Modeling methods. The 99m Tc-DTPA binding rates to human serum albumin increased with the highest concentration. Both drugs FUR and MET displaced 99m Tc-DTPA binding. 99m Tc-DTPA could bind to human serum albumin in many locations in site I and I-II, but strongly bound to site I through hydrogen bonds.

Treatment outcomes of drug resistant tuberculosis patients in Morocco: multi-centric prospective study.

BACKGROUND: Drug resistant tuberculosis is a major public health problem in Morocco and worldwide. Treatment outcome of drug resistant tuberculosis is poor and requires a long period of treatment with many toxic and expensive antituberculosis drugs. The aim of this study is to evaluate treatment outcomes of drug resistant tuberculosis and to determine predictors of poor treatment outcomes in a large region of Morocco. METHODS: It is a multi-centric observational cohort study conducted from January 01, 2014 to January 01, 2016. A questionnaire was established to collect data from clinical charts of patients with confirmed resistant TB. The study was carried out in all the 11 centers located in the Rabat-Salé-Kénitra region of Morocco where drug resistant tuberculosis is treated. Treatment outcomes were reported and the definitions and classifications of these outcomes were defined according to the WHO guidelines. Univariate and multivariate logistic regression were conducted to determine factors associated with poor drug resistant tuberculosis treatment outcomes in Morocco. RESULTS: In our study, 101 patients were treated for drug resistant tuberculosis between January 01, 2014 and January 01, 2016. Patients' age ranged from 9.5 to70 years; 72patients (71.3%) were male and 80 patients (79.2%) were living in urban areas. Thirty two patients were smokers, 74 patients had multidrug-resistant tuberculosis, 25 patients had rifampicin resistance and 2 patients had isoniazid resistance. Treatment outcomes of tuberculosis patients were as follows: 45 patients were cured (44.5%), 9 completed treatment (8.9%), 5 patients died before completing the treatment, 35 patients were lost to follow up (34.6%) and 7 patients had treatment failure. In the multivariate analysis, being a smoker is an independent risk factor for poor treatment outcomes, (p-value = 0.015, OR = 4.355, IC [1.327-14.292]). CONCLUSION: Treatment success outcomes occurred in more than half of the cases, which is lower than the World Health Organization target of at least a 75% success rate. A significant number of patients abandoned their treatment before its completion. These dropouts are a serious public health hazard that needs to be addressed urgently.

Contribution of fibrin glue in the surgery of cyanogenic and non-cyanogenic congenital cardiopathies: retrospective cohort study.

BACKGROUND: Postoperative bleeding in cardiovascular surgery is a frequent and complicated situation for the surgical team, and may also be responsible for significant hospital expenditures. Fibrin glue are indicated in surgery to improve hemostasis when conventional techniques such as compression, sutures or electrocoagulation are insufficient. Through this study, we tried to study the contribution of fibrin glue to the improvement of the clinical parameters (volume of postoperative bleeding, length of stay in intensive care, volume of blood transfusion ...) in two populations having undergone cardiac surgery, one in which we used the fibrin glue and one without fibrin glue. METHODS: This was a retrospective cohort study conducted in the cardiovascular surgery department of our Hospital in Rabat between June 2012 and June 2015. Fibrin glue (Tissucol® of BAXTER) was used in one group with an haemostatic aim. The pre and post-operative clinical data of the patients were analyzed and compared with data from patients who were operated without the use of fibrin glue because it was not yet available in the hospital. The clinical parameters were collected analyzed using the SPSS 13.0 software. RESULTS: One hundred ten patients were included in this study. The fibrin glue was used intraoperatively in 55 patients and not used in 55 patients. 43 (39.1%) had cyanogenic diseases and 67 (60.9%) had non-cyanogenic pathologies. The volume of transfused red blood cells was lower in patients in whom we used biological glue (p = 0.005), as well as the number of days spent in intensive care (p = 0.02). However, the difference was not significant between the two groups for other parameters such as bleeding volume per kg, the number of units of fresh frozen plasma and the platelet units count transfused. CONCLUSIONS: The results we found show that fibrin glue reduces the duration of hospitalization in resuscitation and reduces the number of units of transfused red blood cells to patients after surgery. However, it does not reduce significantly the total postoperative bleeding volume per weight, the number of fresh frozen plasma units or platelets units transfused. The fibrin glue could therefore be of moderate benefit in pediatric cardiac surgery.

Factors associated with asthma control: MOSAR study (Multicenter Observational Study of Asthma in Rabat-Morocco).

BACKGROUND: The purpose of the study is to describe the profile of patients with asthma and to identify the signifiant risks and the protective factors associated with asthma control. METHODS: A prospective epidemiological study was conducted in three hospitals of Rabat-Morocco and included 396 patients with asthma. Differences in characteristics across the levels of asthma control were compared by the one-way analysis of variance for continuous variables, and chi-square test was used for categorical variables. The risk and protective factors associated with the asthma control levels were determined by Proportional Odds Model (POM) for bivariate and multivariate ordinal logistic regression, also expressed as Odds Ratios (OR) and 95% Confidence Intervals (95% CI). RESULTS: From 7440 patients screened by 28 physicians, 396 were included in study. 53% of the particiants sufferd controlled, 18% had partly controlled and 29% had uncontrolled asthma symptoms. A multivariate ordinal logistic regression analysis showed that having respiratory infections (AOR = 5.71), suffering from concomitant diseases (AOR = 3.36) and being allergic to animals (AOR = 2.76) were positively associated with poor control of asthma. However, adherence to treatement (AOR = 0.07), possession of health insurance (AOR = 0.41) and having more than 2 children (AOR = 0.47) were associated with good asthma control. CONCLUSION: The study established a clinical-epidemiological profile of asthmatic patients in Rabat region in Morocco. By ordinal logistic regression we found that 6 factors - respiratory infections, concomitant diseases, animals allergy, adherence to treatment, health insurance and having more than two children - were associated with asthma control.

[Which place occupies the free drug sample in the prescription of the physicians in Morocco?] / Quelle place occupe l'échantillon médical gratuit dans la prescription des médecins au Maroc ?

OBJECTIVES: Do the state of affairs of the perception of free drug samples by a group of prescribers of drugs in the Morocco. METHODS: This was a cross-sectional study of 381 physicians practising in different sectors (public, private) using a self-administered anonymous questionnaire, conducted between December 2016 and March 2017. The questionnaire focused on assessing the general knowledge of prescriber on free drug sample, medical visit of medical representative of pharmaceutical laboratory, drug prescribing and free drug sample use. RESULTS: In total, 381 prescribers were interviewed. Sex M/F ratio was 0.53 with a mean age of 37.4±11.2 years exerting mainly in the public sector in urban areas. According to surveyed prescribers, the drug specialties presented as free drug sample occupied 52.1 percent of their prescription. The main interest in having the free drug sample was to help the patient at low socioeconomic level but it influences the physician's prescription. CONCLUSION: This survey puts in perspective the place of the free drug sample in the medical prescription with prescribers, in order to raise awareness about the ability of free drug sample to influence the medical prescription although it allows to help the patient low socio-economic level.

Pregnancy outcome following in utero exposure to azathioprine: A French comparative observational study.

AIM OF THE STUDY: To evaluate whether azathioprine exposure during pregnancy increases the risk of birth defects and prematurity. METHOD: Prospective comparative observational study using the French pregnancy database TERAPPEL. To evaluate birth defects, outcomes of pregnancies exposed to azathioprine during the 1st trimester were prospectively assessed and compared to that of pregnancies exposed to another drug used for the same indications. Secondly, the rate of preterm births was compared between fetuses exposed to azathioprine at least during the third trimester and those exposed during the first trimester only. RESULTS: From 447 requests for a risk assessment for women receiving azathioprine during pregnancy, 193 pregnancies meet inclusion criteria. One hundred and twenty-four of them were exposed to azathioprine during the 1st trimester and were compared to that of 124 pregnancies exposed to another drug used for the same indication. Azathioprine use during the first trimester was not statistically associated with the risk of all birth defects ([7.3% vs. 5.4%]; [OR=1.36; 95%CI: 0.44-4.20]) nor with major birth defects (5.2% vs. 1.8% [OR=2.96; 95%CI: 0.56-15.64]). The rate of preterm births (22.5% vs. 27.3%, P=0.579) was similar regardless of the exposure period to azathioprine (at least during the third trimester or during the first trimester only). CONCLUSIONS: This study confirms that first trimester exposure to azathioprine is not associated with an elevated rate of birth defects and that the high rate of preterm births among women exposed to azathioprine is probably explained by the underlying maternal disease.

Tumor Necrosis Alpha (TNF-α) Antagonists Used in Chronic Inflammatory Rheumatic Diseases: Risks and their Minimization Measures.

Tumor necrosis factor alpha (TNF- α) inhibitors are widely employed for the management of chronic inflammatory rheumatism. However, their usage carries significant risks, including site and infusion reactions, serious infections, malignancy, heart failure autoimmune and demyelinating disorders. These risks are comprehensively outlined in risk management plans (RMPs) associated with these molecules. RMP provides information on the safety profile of a medicinal product as well as the measures that will be taken to minimize risks; these are known as risk minimization measures. These measures are divided into routine measures related to elements, such as the summary of product characteristics, labeling, pack size, package leaflet, or legal supply status of the product, while additional measures may include educational programs, including tools for healthcare providers and patients, controlled access or pregnancy prevention programs, among others. Additional measures can consist of one or more interventions that need to be implemented in a sustainable way in a defined target group, while respecting the timing and frequency of any intervention and procedures to reach the target population. An evaluation of the effectiveness of these measures is required to determine whether or not an intervention has been effective. This comprehensive review offers an in-depth exploration of the current treatment, uses, and associated risks of TNF-α inhibitors. Additionally, it provides a detailed account of risk minimization measures and risk management practices while shedding light on their real-world implementation and effectiveness.

Incitement to misuse of corticosteroids by Arab YouTubers in a local context.

BACKGROUND: The ubiquity of social media has ushered in an era where uncontrolled content sharing extends to all subjects, including sensitive topics such as medication consumption. OBJECTIVE: To quantify the prevalence of YouTube videos providing information on glucocorticoids and to underscore the risks associated with inaccurate information, which might inadvertently promote inappropriate use of these medications. METHODS: The YouTube videos were selected using predefined keywords from February 20 to March 4, 2023. The videos were categorized into two groups. Category 1 promotes the misuse of corticosteroids, while Category 2 raises awareness about the risks associated with these drugs. RESULTS: In total, 843 YouTube videos were included. Approximately 76% of the creators were women. Of these, category 1 videos (69.63%) predominated over Category 2 videos (30.37%). Regarding Category 1, dexamethasone was mentioned in 41.53% of cases, followed by hydrocortisone (17.30%). According to these YouTubers, these products/medications are mainly obtained from community pharmacies (58.09%), online shops (20.01%), and through illicit markets and the black market (13.46%). Weight gain was the most common objective, according to 32.62% of the YouTubers. CONCLUSION: This study highlights the prevalence of YouTube videos regarding the misuse of corticosteroids. The common focus on weight gain as an objective underscores the importance of educating content creators and viewers about responsible corticosteroid use. Targeted interventions are needed to promote safe and informed medication practices within this online environment.

Assessment of anti-hyperglycemic and anti-hyperlipidemic effects of thiazolidine-2,4-dione derivatives in HFD-STZ diabetic animal model.

Type 2 diabetes mellitus (T2DM) is a chronic endocrine/metabolic disorder characterized by elevated postprandial and fasting glycemic levels that result in disturbances in primary metabolism. In this study, we evaluated the metabolic effects of thiazolidine-2,4-dione derivatives in Wistar rats and Swiss mice that were fed a high-fat diet (HFD) for 4 weeks and received 90 mg/kg of streptozotocin (STZ) intraperitoneally as a T2DM model. The HFD consisted of 17% carbohydrate, 58% fat, and 25% protein, as a percentage of total kcal. The thiazolidine-2,4-dione derivatives treatments reduced fasting blood glucose (FBG) levels by an average of 23.98%-50.84%, which were also improved during the oral starch tolerance test (OSTT). Treatment with thiazolidine-2,4-dione derivatives also improved triglyceride (TG), low-density lipoprotein cholesterol (LDL-c), and total cholesterol levels (P < 0.05). The treatment intake has also shown a significant effect to modulate the altered hepatic and renal biomarkers. Further treatment with thiazolidine-2,4-dione derivatives for 28 days significantly ameliorated changes in appearance and metabolic risk factors, including favorable changes in histopathology of the liver, kidney, and pancreas compared with the HFD/STZ-treated group, suggesting its potential role in the management of diabetes. Thiazolidine-2,4-dione derivatives are a class of drugs that act as insulin sensitizers by activating peroxisome proliferator-activated receptor-gamma (PPAR-γ), a nuclear receptor that regulates glucose and lipid metabolism. The results of this study suggest that thiazolidine-2,4-dione derivatives may be a promising treatment option for T2DM by improving glycemic control, lipid metabolism, and renal and hepatic function.

Bioassay-guided isolation of anti-inflammatory and antinociceptive metabolites among three Moroccan Juniperus leaves extract supported with in vitro enzyme inhibitory assays.

ETHNOPHARMACOLOGICAL RELEVANCE: Herbs of the genus Juniperus (family Cupressaceae) have been commonly used in ancestral folk medicine known as "Al'Araar" for treatment of rheumatism, diabetes, inflammation, pain, and fever. Bioassay-guided isolation of bioactives from medicinal plants is recognized as a potential approach for the discovery of novel drug candidates. In particular, non-addictive painkillers are of special interest among herbal phytochemicals. AIM OF THE STUDY: The current study aimed to assess the safety of J. thurifera, J. phoenicea, and J. oxycedrus aqueous extracts in oral treatments; validating the traditionally reported anti-inflammatory and analgesic effects. Further phytochemical investigations, especially for the most bioactive species, may lead to isolation of bioactive metabolites responsible for such bioactivities supported with in vitro enzyme inhibition assays. MATERIALS AND METHODS: Firstly, the acute toxicity study was investigated following the OECD Guidelines. Then, the antinociceptive, and anti-inflammatory bioactivities were evaluated based on chemical and mechanical trauma assays and investigated their underlying mechanisms. The most active J. thurifera n-butanol fraction was subjected to chromatographic studies for isolating the major anti-inflammatory metabolites. Moreover, several enzymatic inhibition assays (e.g., 5-lipoxygenase, protease, elastase, collagenase, and tyrosinase) were assessed for the crude extracts and isolated compounds. RESULTS: The results showed that acute oral administration of the extracts (300-500 mg/kg, p. o.) inhibited both mechanically and chemically triggered inflammatory edema in mice (up to 70% in case of J. thurifera) with a dose-dependent antinociceptive (tail flick) and anti-inflammatory pain (formalin assay) activities. This effect was partially mediated by naloxone inhibition of the opioid receptor (2 mg/kg, i. p.). In addition, 3-methoxy gallic acid (1), quercetin (2), kaempferol (3), and ellagic acid (4) were successfully identified being involved most likely in J. thurifera extract bioactivities. Nevertheless, quercetin was found to be the most potent against 5-LOX, tyrosinase, and protease with IC50 of 1.52 ± 0.01, 192.90 ± 6.20, and 399 ± 9.05 µM, respectively. CONCLUSION: J. thurifera extract with its major metabolites are prospective drug candidates for inflammatory pain supported with inhibition of inflammatory enzymes. Interestingly, antagonism of opioid and non-opioid receptors is potentially involved.

Sequential therapy versus standard triple-drug therapy for Helicobacter pylori eradication: a prospective randomized study.

PURPOSE: Eradication rates following standard triple therapy for Helicobacter pylori infection are declining. Recent studies, conducted in a number of countries, have shown that sequential therapy for H. pylori infection yields high cure rates. AIM: To compare the efficacy and tolerability of a sequential regimen as a first-line treatment of H. pylori infection with a standard triple treatment regime in Morocco. METHODS: A total of 281 naive H. pylori-infected patients, confirmed by histological examination, were assigned randomly to one of two treatment groups: standard triple therapy [omeprazole (20 mg bid) + amoxicillin (1 g bid) + clarithromycin (500 mg bid) for 7 days] or sequential therapy [omeprazole (20 mg bid) + amoxicillin (1 g bid) for 5 days, followed by omeprazole (20 mg bid) + tinidazole (500 mg bid) + clarithromycin (500 mg bid) for an additional 5 days]. H. pylori eradication was checked 4-6 weeks after treatment initiation by using a ¹³C-urea breath test. Compliance and adverse events were assessed. RESULTS: The two groups did not differ significantly in gender, age, previous disease history, endoscopic and histological features and smoking. The intention-to-treat and per-protocol eradication rates were 65.9 and 71 % in the standard triple therapy group, and 82.8 and 89.9 % in the sequential therapy group, respectively. The eradication rate was significantly higher in the sequential therapy group than in the standard triple therapy group (p < 0.001), There was no statistically significant difference in compliance (97.5 vs. 96.3 %) and incidence of side-effects (27.5 vs. 27.9 %) between the two groups. CONCLUSIONS: Based on our results, we conclude that for eradication of H. pylori infection, the 10-day sequential therapy is more effective than the standard triple therapy and is equally tolerated. These results confirm those of other studies in other countries.

A Novel Approach for Therapeutic Drug Monitoring of Valproic Acid Using FT-IR Spectroscopy and Nonlinear Support Vector Regression.

BACKGROUND: Recent technological progress has bolstered efforts to bring personalized medicine from theory into clinical practice. However, progress in areas such as therapeutic drug monitoring (TDM) has remained somewhat stagnant. In drugs with well-known dose-response relationships, TDM can enhance patient outcomes and reduce health care costs. Traditional monitoring methods such as chromatography-based or immunoassay techniques are limited by their higher costs and slow turnaround times, making them unsuitable for real-time or onsite analysis. OBJECTIVE: In this work, we propose the use of a fast, direct, and simple approach using Fourier transform infrared spectroscopy (FT-IR) combined with chemometric techniques for the therapeutic monitoring of valproic acid (VPA). METHOD: In this context, a database of FT-IR spectra was constructed from human plasma samples containing various concentrations of VPA; these samples were characterized by the reference method (immunoassay technique) to determine the VPA contents. The FT-IR spectra were processed by two chemometric regression methods: partial least-squares regression (PLS) and support vector regression (SVR). RESULTS: The results provide good evidence for the effectiveness of the combination of FT-IR spectroscopy and SVR modeling for estimating VPA in human plasma. SVR models showed better predictive abilities than PLS models in terms of root-mean-square error of calibration and prediction RMSEC, RMSEP, R2Cal, R2Pred, and residual predictive deviation (RPD). CONCLUSIONS: This analytical tool offers potential for real-time TDM in the clinical setting. HIGHLIGHTS: FTIR spectroscopy was evaluated for the first time to predict VPA in human plasma for TDM. Two regressions were evaluated to predict VPA in human plasma, and the best-performing model was obtained using nonlinear SVR.
