The role of N-acetylcysteine (NAC), a glutathione (GSH) precursor, was investigated in protection against isoniazid-(INH) and rifampicin-(RIF) induced oxidative hepatic injury in young Wistar rats. The hepatotoxic dose of INH and RIF was 50 mg kg-1 day-1 each and the hepatoprotective dose of NAC was 100 mg kgday-. All drugs were administered intraperitoneally (i.p.) in sterile water (4.0 ml kg-1 day-1) over a period of 3 weeks. Status of oxidative/antioxidative profiles was the mechanistic approach to assess the hepatotoxicity and/or hepatoprotection. The oxidative injury in INH-RIF co-exposed animals was closely associated with significant decline of GSH and related thiols, as well as with compromised antioxidant enzyme system. The oxidative stress was further supported by increased lipid peroxidation observed in these animals. The co-administration of NAC prevented the induction of oxidative stress in INH-RIF co-exposed animals. The amelioration of oxidative stress by NAC was faithfully reflected as normal morphology in these animals, except the presence of mild degree of portal triaditis in one animal co-exposed to INH-RIF and NAC. In contrast, the animals co-exposed to INH-RIF alone showed histological lesions which ranged from intralobular inflammation to patchy necrosis. These results suggest that INH-RIF-induced oxidative injury can be prevented by supporting the cellular antioxidant defense mechanism by NAC.

Celiac disease is highly prevalent in patients with type 1 diabetes mellitus (11.1%) and majority of them (90.5%) were diagnosed on screening. Routine screening is required for early diagnosis and combat associated co-morbidities.

Terlipressin may be as effective as intravenous albumin in preventing paracentesis-induced circulatory dysfunction in patients with cirrhosis after therapeutic paracentesis.
