A standard HD session profoundly affected aortic BP waveform characteristics, with a reduction in wave reflection in 88% of patients. However, restoration by HD of a normal aortic waveform was unusual. Patients whose waveform remained abnormal after HD had larger more dilated LV chambers than did those patients for whom HD restored "normal" arterial hemodynamics.

ARF after treatment with rifampicin is not an uncommon condition, especially when tuberculosis prevalence is high, but renal prognosis is usually favourable. Thrombocytopenia, immune haemolytic anaemia, and intravascular haemolysis are frequent complications which are associated with a more severe renal injury.

Haemodialysis increases the QTc interval in ESRD patients, mainly related to rapid changes in electrolyte plasma concentrations. However, the impact on QTc dispersion is less important in the absence of significant coexisting cardiac disease.

Renal transplantation is associated with marked improvements in vascular structure and function to a profile comparable to essential HTA patients.

HCV infection is endemic among dialysis centres in Moldavia. Apart from previously well-known risk factors for hepatitis infection, our study demonstrates the negative impact of socio-economic underdevelopment. Simple measures such as enforced general asepsia rules, careful disinfection and equipment sterilization, routine testing of patients from economically disadvantaged areas and monthly, serial determination of hepatic enzymes should be the common practice in dialysis centres in Romania.
