Costs of high-dose salvage therapy and blood stem cell transplantation for resistant-relapsed malignant lymphomas in a southern Italian hospital.

BACKGROUND AND OBJECTIVE: Analysis of costs of high technological procedures such as peripheral blood stem cell (PBSC) autotransplantation in lymphomas are generally finalized at disclosing whether the improvement of survival in a subset of patients is cost effective and whether the cost of the procedure could be reduced. With the aim of revealing a possibility of reducing costs with respect to conditions of safety, we present our experience with PBSC autotransplantation in a particularly poor prognosis subset of patients with lymphoma. DESIGN AND METHODS: The expenses are analyzed for groups of cost and main resources necessary at unitary cost are considered separately. Groups of cost include various phases of the PBSC autotransplantation such as preparative procedures, execution of myeloablative therapy, reinfusion of CD34 cells, supportive therapy after reinfusion until discharge of the patient, general support for the management of patient. All costs are calculated according to 1997 prices and salaries and reported in dollars. The analysis was conducted on 21 patients with lymphoma resistant to other therapies treated by myeloablative therapy and PBSC autotransplantation in an hematologic unit in an open ward; the assistance was provided by staff not exclusively dedicated to bone marrow transplant procedures, with some help from a family member. RESULTS: The PBSC procedure, including all phases, costs from $17,761.9 to $18,259.9 depending on the type of myeloablative therapy employed; the mean cost was $18,092.6. The preparative phase with mobilization of CD34 cells, cryopreservation and reinfusion costed $3,538.7 (19.6% of the total cost); a major cost of this phase was cryopreservation and CD34 manipulation ($857.1). The second phase with myeloablative therapy and reinfusion of CD34 cells had a mean cost of $2,785.9 (15.4% of the total cost); a major cost of this phase was the hospitalization ($1,119.8). The third phase of patient's support after treatment had a total cost of $7,649 (42.3% of the cost of the total procedure) with the major cost being due to hospitalization ($2,571) calculated on a mean of 15 days after the reinfusion of CD-34. The last group of costs, including management support, accounted for $4,119 (22.7%) with a major cost being amortization of the structure ($1,600). The general cost for nurse's assistance to the patient was $1,355.1 (7.5%). INTERPRETATION AND CONCLUSIONS: A procedure of PBSC autotransplantation in resistant lymphoma is affordable without the strict precautions generally given in intensive care units. This provides a substantial reduction of expenses because of the low number of specifically trained staff members and the generally low cost of the necessary supplies. Before, however, proposing PBSC autotransplantation in most patients with resistant lymphoma, an evaluation of whether costs could be further reduced and whether the procedure has a cost benefit impact is needed.

Oral iron chelating therapy. A single center interim report on deferiprone (L1) in thalassemia.

BACKGROUND AND OBJECTIVE: Deferiprone (L1) is a largely studied oral chelator in clinical setting, however, no definite conclusions concerning efficacy and toxicity still could be drawn. In an ongoing prospective trial with L1, we evaluated the efficacy and tolerance-toxicity in patients with thalassemia major previously treated by desferrioxamine (DFO); the specific aim of the study is to demonstrate that L1 could be an alternative to DFO in some patients with an acceptable toxicity. DESIGN AND METHODS: Sixty-nine patients over 13 years of age with poor compliance to DFO were considered for the study. The design included a liver biopsy before starting L1 in all patients in order to define liver siderosis either by histologic grading or by hepatic iron concentration (HIC); only patients with a minimum HIC of 4 mg/g dry weight entered the study. A repetition of the liver biopsy after one year of L1 was planned; further evaluations included serum ferritin, plasma iron, transferrin TIBC and iron urine excretion. L1 was given at 70 mg/kg/day in three divided doses. Toxicity was monitored either clinically or by controlling liver, kidney and marrow function by specific tests. Concerning clinical characteristics 52 patients showed hypogonadism (78%), 39 growth retardation (58%), 6 diabetes (9%), 4 cardiomyopathy (6%), 9 hypothyroidism (12%); 45 patients had chronic liver damage (65%). RESULTS: We focus this report on data collected in a group of 29 patients with a minimum follow-up of one year (14-33 months). The mean ferritin value was 3748 ng/mL (range: 200-10,000) and 2550 ng/mL (range: 80-14,500), before and while on L1 therapy, respectively (p = 0.001); the mean sideruria changed from 17.25 mg/dL (range: 5.4-50) to 20.98 mg/dL (range: 10-40), on DFO and L1, respectively (p = 0.078); the ratio between plasma iron (sideremia) and transferrin TIBC changed from 0.96 with DFO to 0.86 with L1 (0.014). A correlation with grade of liver siderosis and serum ferritin (p = 0.069) and iron urine excretion (p = 0.008) was recorded. The judgement of efficacy showed that L1 was effective (EF) in 9 patients, no assessable (UN) in 11 patients, not effective (NE) in 2 patients and with no advantages with respect to DFO in 7 patients. Liver biopsy was repeated in 20 patients showing a reduction of grade of liver siderosis and iron content in 7 patients. Clinical toxic effects of L1 were gastric intolerance (one patient), joint pain (three patients) and mild and temporary neutropenia (one patient). INTERPRETATION AND CONCLUSIONS: This preliminary experience shows that L1 is effective in several patients with thalassemia with poor compliance to DFO and to improve iron burden and iron excretion with generally minor side effects. L1 could be an alternative to DFO in some patients, however the recognition of neutropenia warrants a careful evaluation of patients and efforts finalized to early recognition of those to be addressed with this new and still experimental therapy.

[The use of HIV-1 protease inhibitors. Their effects on AIDS-correlated outpatient and hospitalization activities. A catchment area study]. / Impiego degli inibitori della HIV-1 proteasi. Effetti sull'attività ambulatoriale e sull'ospedalizzazione correlate all'AIDS. Una indagine nell'area jonica.

OBJECTIVE: To evaluate the effects of the use of protease inhibitors (IP) on the out-patient department's activities and hospitalizations of HIV-1 infected subjects. METHODS: From the December 1996 IP was available in our hospital, so the years 1996 and 1997 were studied. RESULTS: In the year 1997, 336 patients were visited with an increase of the 41% compared with the year 1996. In the 1997 the 45.2% of hospitalizations were related to AIDS, while in the year 1996 the 65.4% of them were related to AIDS. CONCLUSIONS: The use of IP had increased the activities of the out-patient department and certainly had a role in reducing the hospitalizations related to AIDS.
