First report of genotype e of hepatitis B virus in an Indian population.

Twenty-one hepatitis B virus (HBV) isolates from the state of Haryana (North India) were studied for genotype, subgenotype, serotype distribution and precore mutations. Assays of alanine aminotransminase (ALT) and HBeAg were performed on all samples. Genotypes, subgenotypes and serotypes were determined by amplification of pre-S1/S2 regions followed by RFLP and also by phylogenetic analysis of amplified products.

Paroxysmal nocturnal hemoglobinuria clone in a case of myelodysplastic syndrome rapidly progressing to acute leukemia.

Myelodysplastic syndrome (MDS) comprises a group of stem cell disorders with considerable clinical and morphological heterogeneity. We report a case of MDS in a middle-aged male with clinical features of sepsis, dysplastic neutrophils and 6% blasts on bone marrow aspirate. A clone of neutrophils with deficient expression of CD16, CD55 and CD59 was found.
