Drug-Induced Hypouricemia.

Hypouricemia is defined as a serum uric acid concentration of ≤ 2.0 mg/dL or 119 μmol/L. Hypouricemia may occur secondarily to a number of underlying conditions, including severe hepatocellular disease, neoplasia, defective renal tubular reabsorption of uric acid, inherited metabolic defect in purine metabolism, and drugs.

Drug-induced hyperuricaemia and gout.

Hyperuricaemia is a common clinical condition that can be defined as a serum uric acid level >6.8 mg/dl (404 µmol/l). Gout, a recognized complication of hyperuricaemia, is the most common inflammatory arthritis in adults.

Mortality among Patients with Nosocomial Infections in Tertiary Intensive Care Units of Sahloul Hospital, Sousse, Tunisia.

Background: Nosocomial infections are public health issues that are associated with high mortality in intensive care units. This study aimed to determine nosocomial infection-associated mortality in Tunisian intensive care units and identify its risk factors.

Methods: A prospective cohort study was carried out in intensive care units of a Tunisian University Hospital.

Drug-Induced Hyperglycaemia and Diabetes.

Drug-induced hyperglycaemia and diabetes is a global issue. It may be a serious problem, as it increases the risk of microvascular and macrovascular complications, infections, metabolic coma and even death. Drugs may induce hyperglycaemia through a variety of mechanisms, including alterations in insulin secretion and sensitivity, direct cytotoxic effects on pancreatic cells and increases in glucose production.

A Rare Case of Azathioprine-Induced Sweet's Syndrome in a Patient with Crohn's Disease.

Sweet's syndrome has been reported in association with inflammatory diseases such as Crohn's disease. It has also been reported in association with several drugs. Here, we report a rare case of Sweet's syndrome induced by azathioprine in a patient with Crohn's disease.

Pustular drug hypersensitivity syndrome due to allopurinol.

Allopurinol hypersensitivity syndrome (AHS) is a severe drug reaction. It is characterized by rash, fever, and internal organ involvement. It may present in different clinical forms.

In silico screening and study of novel ERK2 inhibitors using 3D QSAR, docking and molecular dynamics.

ERK2 is a dual specificity protein kinase, part of the Ras/Raf/MEK/ERK signal transduction cascade. It forms an interesting target for inhibition based on its relationship with cell proliferation and oncogenesis. A 3D QSAR pharmacophore model (Hypo1) with high correlation (r=0.

Drug-induced hyperkalemia.

Hyperkalemia is a common clinical condition that can be defined as a serum potassium concentration exceeding 5.0 mmol/L. Drug-induced hyperkalemia is the most important cause of increased potassium levels in everyday clinical practice.

Toxic epidermal necrolysis: a retrospective analysis of 17 cases from central Tunisia.

Toxic epidermal necrolysis (TEN), also known as Lyell's syndrome, is a rare, life-threatening and wide-spread exfoliative disease of the skin and mucous membrane that is most commonly drug-induced. We retrospectively reviewed the charts of 17 patients who suffered from TEN in Farhat Hached University Hospital, Sousse, Tunisia over a 19-year period from January 1994 to January 2013. Causality for suspected drugs was assessed by means of the Naranjo adverse drug reaction (ADR) probability scale.

Insight into TPMT(∗)23 mutation mis-folding using molecular dynamics simulation and protein structure analysis.

Thiopurine S-methyltransferase (TPMT) is an important enzyme that metabolizes thiopurine drugs. This enzyme exhibits a large number of interindividual polymorphism. TPMT(∗)23 polymorphism has been reported in a few cases in the world in co-dominance with TPMT(∗)3A.

Drug-induced hypoglycaemia: an update.

Drugs are the most frequent cause of hypoglycaemia in adults. Although hypoglycaemia is a well known adverse effect of antidiabetic agents, it may occasionally develop in the course of treatment with drugs used in everyday clinical practice, including NSAIDs, analgesics, antibacterials, antimalarials, antiarrhythmics, antidepressants and other miscellaneous agents. They induce hypoglycaemia by stimulating insulin release, reducing insulin clearance or interfering with glucose metabolism.

Drug-induced hypokalaemia.

Hypokalaemia (defined as a plasma potassium concentration<3.5 mEq/L) is a common electrolyte abnormality in clinical practice. Drugs are a common cause of either asymptomatic or symptomatic hypokalaemia.

Captopril-induced lichen planus pemphigoides.

Purpose: To report a rare case of lichen planus pemphigoides (LPP) possibly induced by captopril.

Case Summary: A 74-year-old woman developed pruriginous and bullous lichenoid eruption after starting captopril for hypertension. Histopathological and immunological features were consistent with the diagnosis of LPP that was managed by discontinuing captopril and corticosteroid therapy.
