Периневральная лимфоидная инфильтрация при хроническом панкреатите, аденокарциноме поджелудочной железы и хроническом холецистите

Периневральная лимфоидная инфильтрация при хроническом панкреатите, аденокарциноме поджелудочной железы и хроническом холецистите

Abstract

Objective: to study the quantitative and qualitative composition of perineural lymphoid infiltration in chronic pancreatitis and pancreatic cancer. Methods. The histological specimens of 28 patients with chronic pancreatitis, 12 patients with pancreatic cancer and 1 patient with chronic cholecystitis who had undergone the surgery of the head of pancreas were studied. Immunohistochemical expression of CD-45, CD-20, CD-5, CD-3 and CD-79 was studied in 14 cases (10 cases of chronic pancreatitis, 3 cases of pancreatic adenocarcinoma in chronic pancreatitis background disease and 1 case of chronic cholecystitis). Results. Hyperplasia and hypertrophy of nerve trunks in the pancreas and parapancreatic adipose tissue were detected in 26 of 28 cases of chronic pancreatitis, in 9 of 12 cases of pancreatic cancer and in 1 case of chronic cholecystitis. The perineural lymphoid infiltration was revealed in more than a half of the revealed cases. The considerable variability of qualitative and quantitative cell composition of perineural infiltrate was determined in chronic pancreatitis. Conclusion. The reparative hyperplasia and hypertrophy of nervous tissue is the consequence of primary enzymatic damage of myelin sheaths of nerves in pancreas during acute conditions of chronic pancreatitis. These changes of nerve trunks are accompanied by the development of an autoimmune response which is probably the cause of pancreatic pain in the period between exacerbations of chronic pancreatitis. The ratio of T-cells and B-cells in perineural infiltrate is probably caused by different duration of pathological process.

Цель: пзучение количественного и качественного состава периневральной лимфоидной инфильтрации при хроническом панкреатите (ХП) и раке поджелудочной железы (РПЖ). Материал и методы. Исследованы гистологические микропрепараты операционного материала после резекции головки поджелудочной железы у 28 больных ХП, 12 больных РПЖ и желчный пузырь 1 больного хроническим холециститом. Иммуногистохимические исследования проведены в 14 наблюдениях (10 – ХП, в 3 случаях аденокарциномы поджелудочной железы на фоне ХП и в 1 случае хронического холецистита) с использованием антител к CD-45, CD-20, CD-5, CD-3, CD-79. Результаты. Гиперплазия и гипертрофия нервных стволов в ткани поджелудочной железы и в пара- панкреатической клетчатке была выявлена в 26 из 28 случаев ХП, в 9 из 12 случаев РПЖ и в случае хрони- ческого холецистита. В более чем половине наблюдений она сопровождалась периневральной лимфоидной инфильтрацией. Установлена значительная вариабельность качественного и количественного состава клеток периневральных инфильтратов при ХП. Заключение. Следствием первичного ферментативного повреждения миелиновых оболочек нервов ткани поджелудочной железы при обострении ХП является репаративная гиперплазия и гипертрофия нервной ткани, со- провождающаяся развитием аутоиммунной реакции, что, возможно, и обуславливает наличие болевого синдрома у больных в период между обострениями ХП. Количественное соотношение Т-клеточной и В-клеточной перинев- ральной инфильтрации при ХП, по-видимому, обусловлено различиями в давности патологического процесса.
