Lymphocyte subpopulations and neutrophil function in chronic human Chagas' disease

Subpopulações linfocitárias e função neutrofílica na doença de Chagas humana

Abstracts

The absolute numbers of total leukocytes, lymphocytes, T cells, helper/inducer, suppressor/cytotoxic and B cells were decreased in the peripheral blood of patients with chronic Chagas' disease. Since antilymphocyte antibodies were present only in a minority of patients they probably cannot account for the abnormalities in lymphocyte subsets. Patient neutrophils stimulated with endotoxin-treated autologous plasma showed depressed chemotactic activity and this seems to be an intrinsic cellular defect rather than plasma inhibition. Random migration of neutrophils was normal. Reduction of nitroblue tetrazolium by endotoxin- stimulated neutrophils was also decreased. These findings further document the presence of immunosuppression in human Chagas' disease. They may be relevant to autoimmunity, defense against microorganisms and against tumor cells at least in a subset of patients with more severe abnormalities.

SUMMARY

The absolute numbers of total leukocytes, lymphocytes, T cells, helper/inducer, suppressor/cytotoxic and B cells were decreased in the peripheral blood of patients with chronic Chagas' disease. Since antilymphocyte antibodies were present only in a minority of patients they probably cannot account for the abnormalities in lymphocyte subsets. Patient neutrophils stimulated with endotoxin-treated autologous plasma showed depressed chemotactic activity and this seems to be an intrinsic cellular defect rather than plasma inhibition. Random migration of neutrophils was normal. Reduction of nitroblue tetrazolium by endotoxin- stimulated neutrophils was also decreased. These findings further document the presence of immunosuppression in human Chagas' disease. They may be relevant to autoimmunity, defense against microorganisms and against tumor cells at least in a subset of patients with more severe abnormalities.

Key words: Chagas' disease; Leukopenia; Lymphopenia; lymphocyte subpopulations; Chemotaxis; NBT test; Antilymphocyte antibodies.

RESUMO

Números absolutos de leucócitos e linfócitos, de células T totais, indutoras/auxiliares, supressoras/citotóxicas e de células B estavam diminuídos no sangue periférico de pacientes com doença de Chagas crônica. Como anticorpos antilinfocitários estavam presentes em apenas uma minoria de pacientes, eles provavelmente não são responsáveis pelas anormalidades das subpopulações de linfócitos. Neutrófilos de pacientes estimulados por plasma autólogo tratado por endotoxina mostravam atividade quimiotática diminuída que deve ser devida a um defeito celular intrínseco e não a inibição plasmática. A migração aleatória dos neutrófilos estava normal. A redução do corante "nitroblue tetrazolium" (NBT) por neutrófilos estimulados por endotoxina também estava diminuída nos pacientes. Estes achados estendem a documentação da imunossupressão na doença de Chagas humana. Eles podem ser relevantes para autoimunidade e para defesa contra microorganismos e células tumoráis, pelo menos em um subgrupo de pacientes com anormalidades mais pronunciadas.
