Use of the Splenic and Hepatic Artery for Renal Revascularization in Patients with Atherosclerotic Renal Artery Disease

p = 0.17) and the average number of antihypertensive medications decreased to 1.9 (p= 0.001). During the median follow-up of 33 months, 10 patients died, mainly from cardiac causes. Our experience indicates that the splenic and hepatic arteries provide useful alternatives to renal revascularization in selected circumstances with an acceptable rate of perioperative mortality and morbidity. The expected long-term survival in this group of patients is low.     

Evaluation of Hypertensive Patients after Care Provided by Community Pharmacists in a Rural Setting

We evaluated blood pressure control, quality of life, quality of care, and satisfaction of patients who were monitored by specially trained community pharmacists in a group medical practice. After participating in an intensive skill development program, pharmacists performed in an interdisciplinary team in a rural clinic. The primary objective was assessed by evaluating outcome variables at 6 months compared with baseline in 25 patients randomly assigned to a study group. A control group of 26 patients was also evaluated to determine if outcome variables remained constant from baseline to 6 months. Systolic blood pressure was reduced in the study group (151 mm Hg baseline, 140 mm Hg at 6 mo, p<0.001) and diastolic blood pressure was significantly lower at 2, 4, and 5 months compared with baseline. Ratings from a blinded peer review panel indicated significant improvement in the appropriateness of the blood pressure regimen, going from 8.7 ± 4.7 to 10.9 ± 4.5 in the study group (p<0.01), but they did not change in the control group. Several quality of life scores improved significantly in the study group after 6 months (p<0.05). These included physical functioning (61.6 vs 70.7), physical role limitations (56.8 vs 72.8), and bodily pain (60.0 vs 71.7) at baseline and 6 months, respectively. There were no significant changes in the control group. Patient satisfaction scores were consistently higher in the study group at the end of the study. Our results indicate that when community pharmacists in a clinic setting are trained and included as members of the primary care team, significant improvements in blood pressure control, quality of life, and patient satisfaction can be achieved.

Cell surface accessibility of individual gangliosides in malignant melanoma cells to antibodies is influenced by the total ganglioside composition of the cells.

The reactivity of a panel of antiganglioside monoclonal antibodies with a number of melanoma cell lines having different ganglioside composition profiles was studied. One cell line synthesized only GM3, one produced both GM3 and GD2, 2 had GM3 and GD3 as their major gangliosides, and 2 others synthesized approximately equal amounts of GM3, GM2, GD3, and GD2 gangliosides. Antibody reactivity with viable cells was analyzed by: (a) flow cytometry on suspension cells; and (b) mixed hemagglutination assays or immune adherence assays on monolayer cells in culture. GM3 was efficiently detected only in the cell line having GM3 as its sole ganglioside. In the other cell lines, GM3 was difficult to detect even in cells in which it made up a high proportion (up to 50%) of the total ganglioside content. GM2 was easily detectable only in JB-RH melanoma cells (which contain only GM3 and GM2). GD3 was the most reactive ganglioside in 2 cell lines and GD2 in 2 other lines. In general, the most complex ganglioside present in a cell was the one most accessible to antibody. The differential exposure at the cell surface of specific gangliosides may have implications for antibody-directed tumor detection and therapy and for cell-protein or cell-cell interactions that involve glycolipids.     

Improved results of allogeneic bone marrow transplantation for advanced hematologic malignancy using busulfan, cyclophosphamide and etoposide as cytoreductive and immunosuppressive therapy.

Twenty-four patients between the ages of 8 and 48 years (median 27.5) with high-risk for relapse hematologic malignancy received a marrow transplant from an HLA and MLC compatible sibling donor after chemotherapy with busulfan, 4 mg/kg/day for 4 days by mouth, cyclophosphamide 60 mg/kg/day i.v. for 2 days, and etoposide 60 mg/kg i.v. over 4 h on the first day of cyclophosphamide treatment (BU/CY/VP). Toxicity consisted of mucositis, skin rash, and nausea and vomiting in all patients, transient fever thought to be due to etoposide administration in 16/24 (67%) patients, and clinical veno-occlusive disease (VOD) of the liver in 4/24 (17%). There were nine deaths from causes other than recurrent disease in the first 100 days after transplant and two deaths after day 100, a total transplant mortality of 11/24 (46%). Three patients relapsed, but 10/24 (40%) remain alive and disease free 26-182 weeks (median 60 weeks) from transplant. These results compare favorably with results in a group of 12 similar risk patients treated with total body irradiation (TBI) containing regimens during an overlapping time period. Six of the TBI patients have had persistent or recurrent disease and only two (17%) are currently alive and disease free. The probability of disease persistence or relapse is 67% in the TBI group and 20% in the BU/CY/VP group (p less than 0.02).     

Cerebral infarction associated with protein C deficiency following allogeneic bone marrow transplantation.

Hypercoagulable states associated with deficiencies in circulating anticoagulant protein C occur after chemotherapy for a variety of malignant diseases. Protein C deficiency also occurs following bone marrow transplantation (BMT) and may be responsible for a variety of transplantation-associated complications. We report the case of a child who suffered a stroke associated with low protein C antigen and activity occurring 11 months after allogeneic BMT. Protein C levels recovered spontaneously by 18 months after BMT. We speculate that the protein C deficiency and and resultant hypercoagulable state led to the stroke, and the deficiency of this anticoagulant was a sequela of the transplant.
