We identified 30 patients with idiopathic NCIPH at our center over the 2 year study period. The clinical presentation and investigations of NCIPH closely mimic cryptogenic cirrhosis. Idiopathic NCIPH should be considered as a differential diagnosis of cryptogenic cirrhosis in India.

Discrete small ulcers less than 2 cm in diameter in the cecum or rectosigmoid, with intervening normal mucosa, were the most common finding on endoscopy in patients with amebiasis. On histology, necrotic material admixed with mucin, proteinaceous exudate and blood clot lining ulcers, significant surface epithelial changes such as shortening and tufting adjacent to sites of ulceration, mild chronic inflammation extending into the deep mucosa and mild architectural alteration were features of amebiasis. Trophozoite forms of ameba were seen in the necrotic material lining sites of ulceration or lying separately, as well as over intact mucosa. Necrotic material lining ulcers was less common in IBD, but chronic inflammation, crypt abscess formation and architectural alteration were more severe.

This study confirms the preponderance of genotype 3 in Indian patients with HCV related chronic liver disease. Severe steatosis was seen only in genotype 3 and Mallory hyaline was very common in genotype 1. The small numbers of patients in non genotype 3 could be a reason for the apparent lack of histological differences between different HCV genotypes. Severe fibrosis seen in older age groups confirms that HCV infection is progressive and major acceleration of the disease process occurs after 40 years of age.
