Immune status of blood product recipients 总被引:1,自引:0,他引:1
Persons with hemophilia are at risk of the acquired immunodeficiency syndrome (AIDS), and clinically asymptomatic hemophiliacs have shown a high incidence of AIDS-like immune abnormalities, facts leading to speculation that many hemophiliacs have been exposed to the AIDS agent through their blood products. We therefore evaluated the immune status of three groups of blood product recipients without AIDS in New York City, including 47 persons with hemophilia A receiving factor VIII concentrate, 50 persons with homozygous beta-thalassemia, and 27 persons with sickle cell anemia receiving frozen-packed RBCs and 20 healthy persons who had not received a transfusion. Hemophiliac participants had significantly lower lymphocyte counts (median, 1,826/cu mm) than did the thalassemic (6,110/cu mm) or anemic (4,443/cu mm) participants, had lower numbers of T-helper lymphocytes (median, 533 cells/cu mm v 1,733 cells/cu mm and 1,554 cells/cu mm), and had a lower T-helper/suppressor ratio (median, 0.8 v 1.8 and 2.1). These differences remained after adjustment for age and sex. Thus, AIDS-like immune abnormalities were found in patients receiving factor concentrate, but not in those receiving RBCs. These defects could be due to both an immunosuppressive effect of the lyophilized factor itself and to contact with the AIDS agent. 相似文献

Prognostic importance of the white blood cell count for coronary, cancer, and all-cause mortality 总被引:11,自引:1,他引:10
The relationship of white blood cell count (WBC) to fatal and nonfatal coronary heart disease (CHD) incidence and all-cause and cancer mortality was assessed in a subset of participants in the Multiple Risk Factor Intervention Trial (MRFIT). For this group of 6,222 middle aged men, total WBC count was found to be strongly and significantly related to risk of CHD, independent of smoking status. Change in WBC count from baseline to the annual examination just prior to the CHD event was found to be a significant and independent predictor of CHD risk. For each decrease in WBC count of 1,000/cu mm the risk for CHD death decreased 14%, controlling for baseline WBC count and other CHD risk factors (smoking, cholesterol level, diastolic blood pressure). The WBC count was strongly related cross-sectionally to cigarette smoking and smoking status as indicated by serum thiocyanate concentration. Smokers on average had a WBC count of 7,750/cu mm compared with 6,080/cu mm for nonsmokers. The WBC count was also significantly associated with cancer death, independent of reported smoking and serum thiocyanate levels. 相似文献

Eight patients had nine episodes of presumed spontaneous bacterial peritonitis (SBP) caused by commensal bacteria that usually inhabit the oropharynx, including Neisseria perflava and the viridans streptococci Streptococcus milleri, Streptococcus mitis, and Streptococcus sanguis. Nonpurulent ascites (ascitic fluid WBC count, less than 1,000/cu mm) was present in four episodes, possibly caused by either bacterial colonization or early peritonitis; purulent ascites was present in five episodes. None died of their infection, and three episodes remitted without treatment. Poor condition of gums and teeth may play a pathogenic role in SBP caused by these bacteria. 相似文献

Data from 14,961 healthy women were analyzed to determine the relative importance of factors that alter the white blood cell (WBC) count. The effects of smoking, oral contraceptive use, and obesity were most striking. A total leukocyte count greater than 10,00/cu mm was found in 44% of obese, heavily smoking women who took oral contraceptives (central 95% of the distribution was 5,800 to 14,200/cu mm) as compared to 2% of women without these attributes (3,500 to 9,400/cu mm). Other factors such as age, time of day, phase of the menstrual cycle, and red blood cell variables were of lesser significance. The use of noncontraceptive estrogenic hormones did not affect the WBC count. Recognition of these findings is important because excessive laboratory studies, lost physician time, and patient inconvenience may thereby be avoided. 相似文献

Immune thrombocytopenia occurred in five patients with cancer receiving alpha-interferon. The median pretreatment platelet count was 217,000/cu mm, which fell to a median of 12,000/cu mm after a median of 25 days of interferon therapy. All had normal numbers of megakaryocytes, with dysplasia noted in three; all four who were tested had platelet-associated immunoglobulin. All had normalization of platelet counts with prednisone therapy. Four tolerated re-treatment with interferon, two with concurrent prednisone administration and two others following splenectomy. Immune thrombocytopenia should be considered in patients who become thrombocytopenic during interferon therapy. 相似文献

Perforated peptic ulcer long-term follow-up. 总被引:1,自引:0,他引:1
A series of 349 survivors of perforated peptic ulcer was followed for periods of up to 23 years. Almost nine out of every 10 patients suffered from dyspepsia during follow-up. Subsequent elective gastroduodenal surgery was required in more than a quarter of the cases. The surgery rate for gastric ulcer was more than one and a half times that for pyloroduodenal ulcer, and for females almost double that for males. The highest rate of all was for females with gastric ulcer, of whom almost one half came for surgery. One in five patients bled during follow-up. One in eight developed stenosis of the stomach of duodenum, and one in 11 perforated again. There was a significantly increased incidence of subsequent perforation and stenosis in those with an initial perforation of 5 mm or more in diameter. Gastric carcinoma occurred in less than 2% of cases and was restricted to cases of pyloroduodenal perforation. When complications occurred, the majority did so within five years. Only 15% of the 262 patients about whom complete information was available had no complications on follow-up. The indications for definitive surgery at perforation should be extended to include perforated gastric ulcer in the female, particularly if the ulcer is large. 相似文献

Leukopenia is a common complication noted in patients receiving radiotherapy and/or chemotherapy but no effective method has been reported so far to correct this complication. In the field of psychiatry, lithium carbonate used in treating depression has been noted to have induced leukocytosis as a side effect. From July 1985 to December 1987, a total of 111 patients receiving radiotherapy and/or chemotherapy with leukopenia were included in this study. There were sixty nine patients who received lithium carbonate and the remaining forty two patients served as control group were allowed to stop their primary treatment temporarily without medication during their period of leukopenia. For the group given lithium carbonate, 79% of the patients were able to recover their white blood count (WBC) above 3,000/cu.mm. within 5 days and finished their primary treatment smoothly. For the control group, it took them on the average about 11.8 days of rest in order to recover their WBC level to 3,000/cu.mm. and above. Reports in the recent literature indicates that the average toxic level is around 1.5 mEq/l to 2.0 mEq/l. In our study, the average serum lithium level before administration is 0.44 mEq/l, it reached 0.59 mEq/l and 1.08 mEq/l after the fifth and the 10th day of intake respectively. From this laboratory data, obviously no patient reached the toxic level and no side effects were noted clinically. Based on these figures, we can see clearly that lithium carbonate can shorten the period of leukopenia in comparison to the control group which was not given any medication. 相似文献

Utility of differential leukocyte counts in cancer management 总被引:1,自引:0,他引:1
In 1,811 adult patients receiving diverse treatments for cancers other than leukemia, the absolute neutrophil count closely paralleled the total leukocyte (WBC) count. All of the 1,260 patients with WBC counts higher than 5,000/cu mm had more than 1,500 neutrophils per cubic millimeter. Routine differential leukocyte counts are rarely useful in managing the cancer therapy for patients with a WBC count greater than 5,000/cu mm, and only add to the cost of their care. 相似文献

Over a five-year period, 1,883 specimens were cultured for mycobacterium tuberculosis (TB) at our hospital. All cultures were negative, and no cases of tuberculous meningitis were diagnosed. Culture rates (percent of CSF specimens cultured for TB) varied from 74% on the Medicine and Neurology services to 6% on the Pediatric service. These culture rates have been stable for five years. These data suggest that on the Medicine and Neurology services, TB cultures of CSF are persistently overutilized. A simple rule of not culturing CSF for TB if results of the CSF analysis are normal (ie, WBC count less than or equal to 4/cu mm, protein level less than or equal to 45 mg/dL, and glucose level greater than or equal to 45 mg/dL) could reduce utilization by at least 50% without adversely affecting quality of care. 相似文献

The ability of lymphocytes to form rosettes with sheep erythrocytes was studied in the acute burn period to quantitate T lymphocytes. Seventeen adult patients with burns of greater than 15% body surface area were studied serially and compared to normal controls. The absolute number of total rosette-forming cells (RFC) averaged 1,229.1 +/- 92.8/cu mm (SEM) for controls. In patients, a comspicuous decrease in absolute number of total RFC occurred at days 3 to 5 postburn (578.0 +/- 144.2/cu mm) (P less than .001) and during days 6 to 10 (799.8 +/- 106.1/cu mm) (P less than .01). Similarly, the percentage total RFC in patients at days 6 to 10 (48.9% +/- 3.3%) was significantly lower than controls (73.9% +/- 0.7%) (P less than .01). The decrease in total RFC did not correlate with the total lymphocyte count or the cortisol level. These findings suggest that T lymphocytes are decreased or have altered rosette-forming ability in the early postburn period and are in accordance with other reports of impaired cellular immunity following burns. 相似文献

Failure of intensive care unit support to influence mortality from pneumococcal bacteremia 总被引:16,自引:1,他引:15
One hundred thirty-four consecutive cases of pneumococcal bacteremia observed during a six-year period were evaluated. One hundred nineteen (89%) were associated with pneumonia. Factors associated with increased mortality were advanced age, a leukocyte count at admission of less than 5,000/cu mm, neoplastic disease, and involvement of two or more pulmonary lobes in patients with pneumonia. Mortality was 30.5% overall, and 76% in patients admitted to the intensive care unit with pneumococcal bacteremia. Pneumococcal infection continues to be an important cause of morbidity and mortality despite modern supportive care and antimicrobial therapy. 相似文献

目的 探讨产前超声诊断胎儿孤立性轻度侧脑室增宽(isolated mild ventriculomegaly,IMVM)的宫内转归及妊娠结局。方法 回顾性分析2010年1月至2015年12月复旦大学附属妇产科医院诊断并能随访的88例IMVM胎儿的产检信息和妊娠结局。依据中孕期胎儿侧脑室宽度进行分组:侧脑室宽度 10~10.9 mm (A组)侧脑室宽度11~12 mm (B组)。采用Pearson χ2检验进行组间率的比较,多因素Logistic回归分析IMVM宫内转归的影响因素。 结果 产前IMVM总体恢复率为73.9%(65/88)。A组恢复率为82.1%(55/67),B组恢复率为47.6%(10/21),组间差异有统计学意义(P<0.05)。多因素Logistic回归分析显示首次检出IMVM时侧脑室宽度≥11 mm (OR=3.297,P=0.047)和首次检出时的孕周(OR=1.381,P=0.040)是影响IMVM宫内转归的危险因素。胎儿出生后随访2~5年,有远期随访结果的64例胎儿中 (64/88,72.7%)58例(58/64,90.6%)生长发育正常,其余胎儿(6/64,9.4%)产后合并智力及语言发育障碍。结论 大多数IMVM胎儿的宫内转归及预后较好;检出IMVM时侧脑室的宽度和孕周影响其宫内转归。 相似文献
