Effects of co-infection with hepatitis C virus and GB virus C on CD4 cell count and HIV-RNA level among HIV-infected patients treated with highly active antiretroviral therapy

The effects of co-infection with hepatitis C virus (HCV) and GB virus C (GBV-C) on CD4 cell counts and plasma HIV-RNA levels has been investigated in HIV-infected patients treated with highly active antiretroviral therapy (HAART). Patients co-infected with HCV and GBV-C experienced a CD4 cell increase during 4 years of HAART, whereas the increase stopped after 2 years in the other groups.     

Effect of cell determinant (CD)34+ cell dose on the cost and consequences of peripheral blood stem cell transplantation for non-Hodgkin's lymphoma patients in front-line therapy

The aim of this study was to assess the effect of cell determinant (CD)34+ cell dose on the cost and consequences of peripheral blood stem cell transplantation for non-Hodgkin's lymphoma (NHL) patients in front-line therapy. Resource utilisation, length of aplasia, overall (OS) and event-free survival (EFS) were assessed for 63 patients. Economic data were calculated taking into account harvest, hospitalisation, blood product requirements and drugs required until discharge. The point of view of the Hospital Institution was chosen. A significantly earlier haematopoietic engraftment was achieved in patients with a count of more than 5×10⁶ CD34+/kg. There were no differences for OS and EFS. A high CD34+ cell content resulted in a total cost saving of $4210. This was principally related to a significant reduction in the length of hospitalisation (−$3010) and platelet and red blood cell transfusions (−$815), although the latter was not significant. Several sensitivity analyses showed the robustness of our results. A CD34+ cell dose higher than 5×10⁶/kg appeared to be optimal for clinical and economic considerations in NHL patients undergoing transplantation in front-line therapy.     

Fetal intracranial hemorrhage. Prenatal diagnosis and postnatal outcomes

Objective: To present our experience with 14 cases of fetal intracranial hemorrhage (ICH).

Methods: Cases of fetal ICH detected in our institution between 2005 and 2016 by ultrasonography. Maternal characteristics, ultrasound and MRI findings, and postnatal outcome were noted.

Results: Twelve cases (86.7%) were identified during a third trimester routine scan at a median gestational age of 30.6 weeks. The ICH was classified as Grade 2 in two cases, Grade 3 in three cases, and Grade 4 in nine cases. Nine cases were bilateral and five were unilateral (four left/one right). The 11 MRI available confirmed grade and location and, in six cases (54.5%), added new findings. There were six terminations of pregnancy, one intrauterine fetal death and seven babies born alive. These were followed up for 28 months (range 3–96). Some grade of neurologic impairment was observed in five children (71.4%, one Grade 3/four Grade 4), mainly mild to moderate motor sequelae.

Conclusion: Diagnosis of fetal ICH is amenable to antenatal US. Most of the cases identified are of high grade and usually detected during the third trimester. MRI is a valuable complementary tool in evaluating ICH. Conversely to that previously reported, postnatal survival is high but it entails the risk of adverse neurologic outcome in most neonates.     

The usefulness of two-dimensional echocardiography in the diagnosis of an interventricular aneurysm]

The ventricular septal defect (VSD) may close spontaneously in the first few years of life. The closure occurs by muscle's growth of the borders of the defect or by the appearance of an aneurysm of ventricular septum composed mostly by tricuspid tissue. We believe that the two-dimensional echocardiography is the best method to determine the mechanisms that take part in the aneurysm formation. The study was carried out on 58 patients with aneurysms of ventricular septum observed in 230 patients with ventricular septal defects. 29 were male and 29 were female patients. The mean age at the time of diagnosis of aneurysm was 30 months (range 1 month-13 years). Forty seven patients had a perimembranous ventricular septal defect (perimembranous inlet 29, perimembranous trabecular nine, perimembranous outlet nine and of mixed's type seven), muscular defect nine (muscular inlet seven, and muscular trabecular two) and VSD closed in two. The size of the defect was 0.47 +/- 0.2 cm (range 0.2-1.1). In 16 the defect was larger than 0.6 cm. Thirty two patients had associated anomalies. On study the aneurysm in relation with tricuspid valve leaflets: in 27 cases (46.3%), the aneurysm was entirely formed by tricuspid septal leaflets tissue (17 had perimembranous ventricular septal defect and seven muscular), in eight (13.6) the aneurysm had tricuspid valve leaflets and interventricular component of the membranous septum tissue (five perimembranous defect and two muscular) and in another 16 cases membranous septum tissue only. In 7 patients the origin of the aneurysm wasn't confirmed.(ABSTRACT TRUNCATED AT 250 WORDS)
