Optimizing tacrolimus therapeutic drug monitoring in Tunisian kidney transplant recipients: exploring the variability in bioavailability and the correlation between pharmacokinetic parameters.

Objectives: While the existing literature extensively covers the topic of tacrolimus variability, it remains crucial to gather data that are tailored to the Tunisian population. Our primary goal was to assess the variability in tacrolimus bioavailability using the Cp(0)/weight dosage ratio in Tunisian kidney transplant patients. We also aimed to determine the correlations between blood trough level (Cp(0)) and the area under the concentration-time curve (AUC0-12 h) in this cohort.

Factors influencing valproic acid trough levels in epileptic children.

Objective: In this study, we aimed to assess main factors influencing the Valproic Acid (V.Acid) plasma trough levels (C0) and to determine their degree of influence on V.Acid C0 in children with epilepsy who had Therapeutic Drug Monitoring (TDM).

Drug-Drug Interaction between Tacrolimus and Fluconazole in a Kidney Transplant Recipient.

We report a case of tacrolimus and fluconazole drug-drug interaction in a 20-year-old female kidney transplant recipient with stable kidney function. The patient's tacrolimus blood concentrations were in the therapeutic range until fluconazole was administrated for Candida albicans infection, on day 58 posttransplant. Tacrolimus blood concentration increased by 125% (18.

Interaction Between Tacrolimus and Proton Pump Inhibitor in a Kidney Transplant Recipient.

We aimed to present a drug monitoring profile of tacrolimus and proton pump inhibitor coadministration in a 23-year-old male patient with a history of high blood pressure who underwent kidney transplant. The patient's serum trough levels of tacrolimus were in the therapeutic range until omeprazole 20 mg daily was prescribed. Tacrolimus trough serum level increased to 29.

Myocarditis following Coronavirus vaccination.

Introduction: Myocarditis is an adverse reaction discovered after the marketing of SARS-CoV-2 mRNA vaccines. Nevertheless, this effect is not mentioned as an adverse reaction in the summary of product characteristics of other types of vaccines against this disease.

Objective: In this work, we aim to present the cases of myocarditis after vaccination against COVID-19 reported to the national Tunisian centre of pharmacovigilance.

Cutaneous adverse effects of antiepileptic drugs.

Antiepileptic drugs (AED) are widely used in therapy. They are mainly indicated in the treatment of epilepsy and some psychiatric pathologies as well as for their analgesic action. Their cutaneous adverse effects (CAE) are common, often mild but sometimes serious.

Erythema Multiforme Reactions Following Pfizer/BioNTech (Tozinameran) Vaccination: Two Case-Reports with Positive Rechallenge and Review of the Literature.

Aim: Pfizer/BioNTech (BNT162b2) is a COVID-19 vaccine with a reassuring safety profile. The main adverse reactions are mild local reactions. Cutaneous reactions are generally minor.

Therapeutic Drug Monitoring of Tacrolimus in Tunisian Renal Transplant Patients during the Tuberculosis Infection: A Retrospective, Observational, Single-centre Analysis.

Unlabelled: Tuberculosis is a challenge in organ transplantation due to the interaction between Anti- Tuberculosis Treatment (ATT) and immunosuppressive drugs, such as Tacrolimus (TAC). This study aimed to assess this interaction and discuss the guidelines used in this specific case.

Methods: A retrospective, observational, single-center analysis was performed at the Department of Clinical Pharmacology (National Centre of Pharmacovigilance, Tunisia).

Statin Associated Muscular Adverse Effects.

Background: Statins are widely used in the treatment of hyperlipidemia and in the prevention of cardiovascular diseases. However, they may induce muscular adverse effects that range from asymptomatic elevation of creatine kinase to life threatening rhabdomyolysis.

Objective: The aim of the study was to describe epidemiological and clinical characteristics of patients with muscular adverse effects.

Humoral and Cellular Immunogenicity of Six Different Vaccines against SARS-CoV-2 in Adults: A Comparative Study in Tunisia (North Africa).

Background: The mass vaccination campaign against SARS-CoV-2 was started in Tunisia on 13 March 2021 by using progressively seven different vaccines approved for emergency use. Herein, we aimed to evaluate the humoral and cellular immunity in subjects aged 40 years and over who received one of the following two-dose regimen vaccines against SARS-CoV-2, namely mRNA-1273 or Spikevax (Moderna), BNT162B2 or Comirnaty (Pfizer-BioNTech), Gam-COVID-Vac or Sputnik V (Gamaleya Research Institute), ChAdOx1-S or Vaxzevria (AstraZeneca), BIBP (Sinopharm), and Coronavac (Sinovac).

Material And Methods: For each type of vaccine, a sample of subjects aged 40 and over was randomly selected from the national platform for monitoring COVID-19 vaccination and contacted to participate to this study.

Seizures after vaccines.

Immunization plays an important role in achieving global health goals. Thus, vaccination is one of the essential means of preventing infectious and viral diseases. The onset of adverse events following immunization (AEFI) is common and most of the time it is a mild effect.

Phylogenetic and amino acid signature analysis of the SARS-CoV-2s lineages circulating in Tunisia.

Since the beginning of the Coronavirus disease-2019 pandemic, there has been a growing interest in exploring SARS-CoV-2 genetic variation to understand the origin and spread of the pandemic, improve diagnostic methods and develop the appropriate vaccines. The objective of this study was to identify the SARS-CoV-2s lineages circulating in Tunisia and to explore their amino acid signature in order to follow their genome dynamics. Whole genome sequencing and genetic analyses of fifty-eight SARS-CoV-2 samples collected during one-year between March 2020 and March 2021 from the National Influenza Center were performed using three sampling strategies.

Comparing real-life carbamazepine exposure between innovator and generic formulation.

Background: Carbamazepine is an anticonvulsant largely used in the treatment of epilepsy. The use of generic antiepileptic drugs (AEDs) is controversial because of the eventual possibility to loss seizures control. The aim of our study was to compare the concentration over dose ratio of two products containing carbamazepine, the innovator (Tégrétol®-NOVARTIS) and the generic (Taver®-MEDOCHEMIE).

Is there a ceiling lamotrigine serum level in epileptic children in remission?

Introduction: Seizure control, in patients with epilepsy, is proportionally associated with health-related quality of life. Antiepileptic therapy leads to seizure remission in most cases. However, some patients are resistant to treatment despite achieving high doses which can be explained by interindividual variability of antiepileptic drugs' metabolism.

DRESS Syndrome Associated with Liposomal Amphotericin-B in a Kidney Transplant Patient: A Case Report.

Introduction: Liposomal amphotericin B is a widely used broad-spectrum antifungal drug. It was developed to reduce nephrotoxicity and maximize the therapeutic utility of amphotericin B in the treatment of invasive fungal infections. Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a severe drug-induced hypersensitivity syndrome commonly associated with aromatic antiepileptic drugs.
