Azithromycin-induced cholestatic hepatitis.

Since its introduction >20 years ago, Azithromycin has been widely used owing to its broad spectrum and good tolerability, especially when used for <7 days. In literature, there are only very few, sporadic reports available of patients developing cholestatic hepatitis following treatment with it. The current case study describes a 69-year old patient, with a medical history that included significant alcohol consumption, who presented with jaundice following a 3-day course of Azithromycin.

Noninvasive markers of fibrosis and inflammation in clinical practice: prospective comparison with liver biopsy.

Background: The efficiency of transient elastography for the assessment of liver fibrosis has been evaluated mainly in patients with chronic hepatitis C and chronic hepatitis B, with few studies with nonviral chronic liver disease (CLD) such as autoimmune hepatitis, alcoholic liver disease and nonalcoholic steatohepatitis. In this study, we examined the value of transient elastography in a number of groups in comparison with the Fibrotest/Actitest (FT/AT), using the liver biopsy (LB) as the reference standard.

Methods: An unselected and consecutive group of 65 patients had an LB either as part of an initial diagnosis or of a follow-up assessment, and in addition had a transient elastography measurement [Fibroscan (FS)] and serum blood tests FT/AT performed before the LB.

Modulation of cholinergic contractions of airway smooth muscle by cathinone: potential beneficial effects in airway diseases.

Infusion of khat leaves is an African traditional remedy used to treat airway diseases. The beneficial effects of khat are thought to be due to the activity of its main active component, cathinone. Cathinone inhibited electric field stimulation-induced acetylcholine release and the contractions of smooth muscle, which could be responsible for the beneficial effects seen in airway disease.

The effect of Khat (Catha edulis) as an appetite suppressant is independent of ghrelin and PYY secretion.

Background: The leaves of the khat plant (Catha edulis) are chewed for their pleasurable effects. Chewing releases cathinone which may decrease appetite through an unknown mechanism. Levels of the peptide ghrelin increase with hunger and decrease immediately post-prandially, while peptide YY is released following a meal.

Khat (Catha edulis): health aspects of khat chewing.

Catha edulis Forsk leaves (khat) are chewed daily by a high proportion of the adult population in Yemen for the mild stimulant effect. Cathinone is believed to be the main active ingredient in fresh khat leaves and is structurally related and pharmacologically similar to amphetamine. The habit of khat chewing is widespread with a deep-rooted sociocultural tradition in Yemen and as such poses a public health problem.
