Drug repurposing : A new fashion for a new hope
The repurposing of drugs is becoming increasingly attractive as it avoids the long process and cost implications associated with bringing a novel drug to market i.e., drug repurposing is cost effective and time saving. This study will discuss the repositioning of several drugs that belong to different pharmaceutical classifications such as antimicrobials (itraconazole and fluoroquinolones), anti-diabetic agents (metformin and sodium glucose co-transporter 2 inhibitors), cardiovascular drugs (β-blockers and digoxin), anticonvulsants (topiramate), immunosuppressants (sirolimus), non-steroidal anti-inflammatory drugs (NSAIDs e.g., COX inhibitors), and cholesterol lowering drugs (statins).
COVID-19: Diagnosis and Treatment
The global coronavirus disease 2019 (COVID- 19) has presented major challenges for clinical laboratories, from initial diagnosis to patient monitoring and treatment. Initial response to this pandemic involved the development, production, and distribution of diagnostic molecular assays at an unprecedented rate, leading to minimal validation requirements and concerns regarding their diagnostic accuracy in clinical settings. In addition to molecular testing, serological assays to detect antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are now becoming available from numerous diagnostic manufacturers. In both cases, the lack of peer-reviewed data and regulatory oversight, combined with general misconceptions regarding their appropriate use, have highlighted the importance of laboratory professionals in robustly validating and evaluating these assays for appropriate clinical use.
Celiac disease
Celiac Disease is a chronic small intestinal immune-mediated enteropathy caused by the ingestion of dietary gluten proteins in genetically susceptible individuals. CD is one of the most common autoimmune diseases, affecting around 1.4% of the population globally . Celiac disease remains a challenging condition because of a steady increase in knowledge tackling its pathophysiology, diagnosis, management, and possible therapeutic options. Finding alternative diet and trying different lifestyle still under debates. However, complete exclusion of the gluten-containing food from the patient's diet is the only effective treatment to avoid the disease complications
Alzheimer's disease : Peptide vaccine and immunotherapy
Peptide vaccines and immunotherapies against aggregating proteins involved in the pathogenesis and progression of Alzheimer's disease (AD) the ẞ-amyloid peptide (Aẞ) and tau are promising therapeutic avenues against AD. Two decades of effort has led to the controversial United States Food and Drug Administration (FDA) approval of the monoclonal antibody Aducamumab (Aduhelm), which has subsequentially sparked the revival and expedited review of promising monoclonal antibody immunotherapies that target Aẞ.
