Cytostatic treatment of glomerular diseases. III. A double-blind cross-over study of the effect of cyclophosphamide report from a copenhagen study group of renal diseases.

Fifty patients with renal glomerular diseases entered a double-blind cross-over study on the effect of cyclophosphamide; 38 had received neither corticosteroids nor cytostatic drugs before joining the study. Cyclophosphamide was given for 4 months in doses decreasing from 3 to 1.5 mg/kg b.wt. Cyclophosphamide caused a 46% decrease in the 24-hour excretion of urinary protein and a decrease in serum creatinine within the normal range. Albumin, transferrin and IgA in urine, as well as albumin clearance and the sieving coefficient of albumin, changed parallel to the total urinary protein. The initial values of proteinuria and serum complement were of prognostic significance for the effect of cyclophosphamide in serum creatinine. We were unable to demonstrate a prognostic significance for the variables: clinical diagnosis, renal histology, arterial BP, initial values of serum creatinine and IgG, IgA and IgM in serum and urine. ESR appeared to be the most reliable acute phase reactant. No differences were found between the changes in renal histology during cyclophosphamide or placebo.

Effect of HAART on health status and hospital costs of severe HIV-infected patients: a modeling approach.

PURPOSE: The purpose of this study was to assess the impact of highly active antiretroviral therapy (HAART) on health status and hospital costs in severe HIV-infected patients who were followed in a French hospital. METHOD: The first 500 patients who received HAART, with CD4 + cell count below 250/mm(3), were considered. Evolution of the distribution of patients among different health states, including death, was modeled through a continuous time Markov model. Hospital financial charges and antiretroviral treatment costs were computed. Health states defined by both CD4 counts and viral load were used to show clinical changes in the patient population over a 14-month period after HAART initiation. The economic impact of HAART initiation was assessed using a simplified model based on CD4 counts only over two 14-month periods, before and after initiation. RESULTS: Between day 0 and month 14, the proportion of patients in the least severe state (CD4 + >100/mm(3) and viral load<500 copies/mL) increased from 1% to 50%, and the proportion with more than 100 CD4 + cells/mm(3) increased from 17% to 80%. Antiretroviral treatments amounted to Fr 2,141 per patient-month before HAART initiation and to Fr 3,093 after. Conversely, hospital charges fell from Fr 5,138 per patient-month to Fr 3,136. CONCLUSION: Our model gives a representation of the effect of HAART on (1) the improvement of patients' health status, (2) the increase of treatment costs, and (3) the reduction of hospital financial charge. Important savings in hospital charges can compensate for the extra cost associated with the initiation of HAART.

[Study of the accumulation of lead in the primary teeth].

The purpose of the study was to determine the accumulation of lead in deciduous teeth in children living in the area of Pamplona (Spain). In this manner, we tried to make a relationship between the quantity of lead accumulated in the tooth against certain factors of exposure that were documented on a questionnaire carried out at the time that the tooth was presented. We analysed 457 deciduous teeth using a technique of microwave digestion follow by Atomic Absorption Spectrometry (AAS), to determine the concentration of lead in the sample. The mean lead concentration was 2.60+/-1.36 microg/g (range 0.25-10.71 microg/g). The lead concentration in our study is inferior to those observed in other European studies.
