Feasibility and safety of autologous bone marrow mononuclear cell transplantation in patients with advanced chronic liver disease.

Aim: To evaluate the safety and feasibility of bone marrow cell (BMC) transplantation in patients with chronic liver disease on the waiting list for liver transplantation.

Methods: Ten patients (eight males) with chronic liver disease were enrolled to receive infusion of autologous bone marrow-derived cells. Seven patients were classified as Child-Pugh B and three as Child-Pugh C.

Distribution of hepatitis B virus genotypes among patients with chronic infection.

Unlabelled: Hepatitis B virus (HBV) can be classified into at least eight genotypes, A-H. We evaluated the distribution HBV genotypes among patients with chronic infection.

Methods: We consecutively evaluated adult patients with chronic HBV infection from Salvador, Brazil.

Association of Helicobacter pylori infection and giardiasis: results from a study of surrogate markers for fecal exposure among children.

Aim: To investigate whether Helicobacter pylori (H pylori) infection is associated with hepatitis A virus (HAV) infection, presence of enteroparasites, and other surrogates of fecal exposure.

Methods: We conducted a cross-sectional study in 121 children consecutively admitted at a pediatric hospital in Salvador, Brazil. H pylori and HAV infection were identified by the presence of serum antibodies.
