ABSTRACT

BACKGROUND: The aim of this study was to assess the feasibility of freezing mobilized peripheral blood progenitor cell (PBPC) components at higher cell concentrations than are classically recommended for bone marrow. This approach might have potential benefits, such as lower cost of processing and storage and less risk of the complications associated with the transfusion of large component volumes and large quantities of DMSO. STUDY DESIGN AND METHODS: In the first phase, small aliquots of 19 apheresis components were cryopreserved at standard and higher cell concentrations (Aliquots A and B, respectively). In the second phase, 21 apheresis components were split into two bags each and frozen at standard (Bag A) and high (Bag B) cell concentrations. The differences in viability, cloning efficiency, and nucleated cell recovery in Bags A and B were examined. Finally, the hematologic recovery of 10 patients who underwent autologous transplantation with PBPC components frozen at high cell concentrations was analyzed. RESULTS: The median cell concentration at freezing was 94 (57-100) x 10(6) per mL and 291 (220-467) x 10(6) per mL for Aliquots A and B, respectively, and 90.9 (45.4-92) x 10(6) per mL and 332 (171-582) x 10(6) per mL for Bags A and B, respectively. The viability was significantly lower in samples frozen at higher cell concentrations: 92 versus 83 percent (p = 0.001) and 87 versus 77 percent (p<0.001) for Aliquots and Bags A and B, respectively. Significant differences were not observed in the recovery of total nucleated cells (102 vs. 101% and 98 vs. 105%) or the cloning efficiency after thawing (13 vs. 16% and 27 vs. 23%) for Aliquots and Bags A and B, respectively. The time to granulocyte engraftment >0.5 x 10(9) per L and platelet engraftment >20 x 10(9) per L was 9 (8-11) and 10.5 (7-21) days, respectively. CONCLUSION: The cryopreservation of PBPC components at standard concentrations and 3.3 (1.8-6.2)-fold cell concentrations has no adverse effect on the function of HPCs after thawing.

ABSTRACT

Autologous bone marrow transplantation (ABMT) offers a therapeutic alternative for children with poor prognosis acute lymphoblastic leukemia (ALL) who lack an HLA-matched sibling donor. The most common cause of treatment failure after ABMT in these patients is leukemia relapse. We have developed an ex vivo autologous marrow purging program for children with ALL using an immunomagnetic method. BM purging has been performed in 37 children with ALL (31 B-lineage ALL and 6 T-lineage ALL) following an indirect method, using panels of mouse monoclonal antibodies (MAbs) directed against B or T cell antigens, Dynabeads M-450 (Dynal) coated with sheep antimouse (SAM) antibodies, and the MaxSep Magnetic Cell Separator (Baxter). Purging efficiency has been assessed by flow cytometry. Considering the limit of detection of target cells 0.1%, the median depletion was 2.0 log (range 0.8- > 2.8 log) for the B-lineage ALL and 2.7 (range 2.2- > 2, 9 log) for the T-lineage ALL patients. Twenty-seven patients have been autografted (6 in first complete remission, CR, 13 in second CR, and 8 in third or subsequent CR). Engraftment has been satisfactory in all of them, reaching levels of 500 neutrophils/mm3 and 20,000 platelets/mm3 after a median of 17 (range 12-39) and 30 (range 13-96) days post-ABMT, respectively. In summary, our results show that this immunomagnetic procedure achieves high levels of target cell depletion and can be safely applied to bone marrow purging in childhood ALL patients.

ABSTRACT

Based on previous experiences in animals and humans, low doses of CD8+ lymphocytes infused together with the marrow graft seem to enhance engraftment after allogeneic T cell-depleted marrow transplantation. From April 1994 to February 1997, 12 patients with chronic myelogenous leukemia in first chronic phase receiving a bone marrow transplant (BMT) from an HLA-identical sibling were included in a pilot study of T cell subset depletion. Total depletion of CD4+ cells of the marrow graft and partial depletion of CD8+ cells was performed by immunomagnetic separation. In order to improve the engraftment rate, we infused a low fixed number of CD8+ lymphocytes (0.25 x 10(6)/kg). All the patients were at high risk of developing acute graft-versus-host disease (GVHD), with a recipient age of >30 years, and/or donor sensitized by previous pregnancies or transfusions. All of them received cyclosporin A and methotrexate post-BMT. No graft failure was observed. The grade III-IV GVHD rate was 16.6%, and the actuarial survival at 3 years is 81.8%. Immunological recovery showed persistent CD8+ HLA-DR+ lymphocytosis 8 months after transplant. Relapses were not observed. This experience shows the importance of CD8+ cells to ensure correct engraftment, decreasing the GVHD rate.

ABSTRACT

Seventeen patients with Philadelphia (Ph) chromosome-positive chronic myeloid leukemia (CML) were treated with the ICE regimen plus G-CSF with the aim of mobilizing and collecting Ph-negative peripheral stem cells (PSC) in the setting of an autotransplant program. Fifteen patients had CML in first chronic phase (CP), and two in accelerated phase (AP). Three patients had been previously treated with interferon alpha 2a (IFN). Twelve patients underwent leukaphereses and a mean of 4.7 x 10(8)/kg mononuclear cells were obtained. Four CP patients did not show a significant mobilization peak of CD34+ cells and leukapheresis was not performed; finally, one patient died before apheresis could be performed. Six of the 12 who underwent leukaphereses obtained more than 1.0 x 10(6)/kg CD34+ cells. Eight of the 12 mobilized patients (67%) obtained a major cytogenetic response, including two complete and six partial; in the remaining four patients minimal or absent cytogenetic responses were observed. A higher rate of Ph purging was obtained in patients mobilized early or showing residual Ph-negative cells before mobilization, even if they were in AP. Infectious complications were frequent with a 38% rate of bacteremia recorded and one case of pulmonary aspergillosis resulting in a toxicity similar to that occurring in acute myeloid leukemia-induction chemotherapy. The ICE regimen can promote 'in vivo' purging of the Ph+ cells in 67% of CML mobilized patients (8/12). Failure of mobilization occurs in 65% of patients (11/17), mainly because of poor CD34+ cell yield.

ABSTRACT

Presentamos dos pacientes de 32 y 38 anos de edad, femenino y masculino respectivamente ambos procedentes del area rural con diagnostico post-operatorio de pneumatosis cystoide intestinal por estenosis de piloro, confirmado por histopatologia y que representan el 0,04// de un total de 4770 cirugias realizadas en el Instituto Gastroenterologico Boliviano Japones de Cochabamba entre abril de 1991 a febrero de 1993. Por la rareza de esta patologia en nuestro medio, se revisa el tema desde el punto de vista estadistico, conceptual, de diagnostico y tratamiento. El diagnostico es esencialmente radiologico pero tambien puede ser un hallazgo quirurgico o de autopsia. El tratamiento se realiza de acuerdo al cuadro desencadenante. Se concluye que la pneumatosis quistica intestinal debe tomarse en cuenta como diagnostico diferencial con otras patologias gastrointestinales.

ABSTRACT

Se presentan tres pacientes masculinos, dos de 23 y uno de 33 anos de edad con diagnostico post-operatorio de abdomen agudo por diverticulo de Meckel complicado, que representa el 0,08 // del total de 3827 cirugias realizadas en el IGBJ de la ciudad de Cochabamba-Bolivia entre abril de 1981 a mayo de 1991. Por la escasa presentacion de esta patologia en adultos se revisa el tema desde el punto de vista conceptual, el diagnostico es clinico-laboratorial y por exclusion. Generalmente son hallazgos quirurgicos. Finalmente, creemos que en toda laparotomia como norma se debe explorar los primeros dos metros distales del ileon en busca del diverticulo y tratarlo de acuerdo a la severidad del cuadro de base, para evitar diversas complicaciones posteriores.

ABSTRACT

Se revisaron 17 H.CI de pacientes operados por peritonitis tuberculosa, que representan el 0.5% de un total de 3.306 cirugias realizadas en el Centro Quirurgico Boliviano Japones (C.G.B.J.) de Cochabamba entre abril de 1981 a marzo de 1990. El 76.5 proviene del area rural y suburbana y de estratos socio economicos bajos. Afecta por igual a todas las edades con discretas variaciones y con predominio del sexo femenino de I,I a I sobre el masculino. Es dificil realizar el diagnostico preoperatorio de peritonitis TBC y casi siempre es un allazgo intraoperatorio que se confirma por laboratorio. En caso de complicaciones viscerales deben ser tratados quirurgicamente como cualquier otro paciente. La peritonitis tuberculosa ascitica represente el 70.6%, la fibro-adhesiva 23.5% y la peritonitis cronica encapsulante el 5.9. La morbilidad fue del 17.7% y la mortalidad de 11.8

ABSTRACT

Se revisaron retrospectivamente 126 historias clinicas de pacientes operados con diagnostico de penetrantes abdominales por armas punzo-cortantes del Servicio de Emergencia del Hospital Clinico Viedma desde 1972 a 1979, correspondiendo al 55% del total de traumas abdominales. Existiendo un predominio del sexo masculino de 7 a 1 sobre el sexo femenino, pacientes que provienen mas del area rural y sub-urbano 77%, de estratos socio-economicos bajos, en edad activa y con repercusion en la produccion. Para el diagnostico de precision, aparte de los antecedentes, la valoracion clinica y examenes de laboratorio, se hace hincapie en el lavado peritoneal a traves de la herida abdominal, de esta manera se evitaran las laparatomias en blanco (exploratorias) que en nuestra serie corresponden al 7.9% se comunica ademas el aumento excesivo de este tipo de lesiones en los ultimos 6 años, los hallazgos operatorios, las diversas tecnicas quirurgicas, la morbimortalidad, el tiempo de hospitalizacion. No se realizo el seguimiento por diversas razones.
