Immune parameters in a population of institutionalized elderly subjects: influence of depressive disorders and endocrinological correlations.

Twenty-six institutionalized elderly subjects, selected as healthy according to the SENIEUR protocol, were compared to adult controls to establish correlations between affective disorders and immune abnormalities and to investigate underlying neuroendocrine mechanisms. After an extensive psychodiagnostic examination, 35% of the aged subjects were classified as depressed. Cutaneous delayed hypersensitivity tests showed reduced responses in the aged, but no correlation was found with the psychological status. Examination of the peripheral blood lymphocyte subsets revealed no imbalance in the percentages of CD3+, CD4+, CD8+ cells in the aged. A slight reduction in the CD4+/CD8+ cell ratio could however be detected in the non-depressed aged, as compared to adult controls. The CD4+/CD45R+ cell subset was reduced in non-depressed aged. The percentage of B lymphocytes was reduced in the aged, mostly in the non-depressed subjects. No changes were detected in the percent of OKDR+ cells. The percentage of CD16+ cells was found unchanged, while that of Leu7+ cells was significantly higher in the aged than in the adults and in the non-depressed than in the depressed aged. Leu7+ cell levels were negatively correlated with the depression score. On double labelling, the percent of CD16+/Leu7+ cells appears increased in the subgroup of depressed aged and positively correlated with age. Plasmatic and urinary cortisol levels were both positively correlated with depression score. Urinary cortisol level was higher in the depressed aged. These parameters, as well as plasmatic ACTH, beta-endorphin and urinary catecholamines, were not correlated with immune responses. Based on these findings, we recommend that the neuroendocrinological conditions should be taken into account when healthy subjects are examined in studies of immune senescence.

Impairment of lymphocyte activities in depressed aged subjects.

Lymphocyte activities were determined in a population of 26 institutionalized aged subjects, selected as healthy according to the SENIEUR protocol and previously reported to display immunological and endocrinological abnormalities correlated with depressive disorders. The lymphocyte mitotic response to PHA, which was reduced in aged as compared to adult subjects, was found to be significantly lower and negatively correlated with the depression score in the elderly subjects. In supernatants of PHA-stimulated lymphocyte culture from aged subjects, IL-2, IL-4 and gamma-IFN levels were very low and more severely affected in the depressed aged group. Each cytokine production was negatively correlated with age and depression score. NK activity was lower in the aged and it could be augmented by the addition of IL-2 or alpha-IFN, even though to a lesser extent than in the adult subjects. The nondepressed aged displayed higher levels of IL-2 inducible NK activity than the depressed aged subjects. IL-2 and alpha-IFN stimulated NK activities were negatively correlated with depression score. The present work indicates that the psychological status could affect lymphocyte reactivity in the aged. Given the relatively high frequency of affective disorders in these subjects, the psychological status should be considered in studies of immune senescence.

Effects of hospitalization on affective status of elderly patients.

The effects of hospitalization on affective status were assessed by an original protocol in 214 consecutive elderly patients (mean age = 78.3 +/-5.0 years, range = 70-92 years). Psychological decompensation was significantly related to length of stay (p less than 0.01) and drug use (p less than 0.05) and unaffected by sex, marital status, prior living place, diagnostic category. Affective status and functional status were directly correlated (p less than 0.0001), although in 51% of medical patients the affective status worsened or remained unchanged despite improved physical function. Improvement in affective status occurred more frequently in surgical patients (p less than 0.001) due to psychological improvement following surgery. Physicians providing medical and surgical care for geriatric patients must remain aware of the patients' emotional response to hospitalization and illness, given the accompanying risk for psychological decompensation.

Autopsy rate in younger and older hospitalized patients.

A retrospective study of the autopsy rate of the clinico-pathological correlations was made in a group of inpatients. The trend of autopsy rate was observed in all inpatients died in a university hospital during a nine year period (from 1975 to 1983). The agreement between the clinical and pathological death diagnosis was retrospectively controlled in 294 consecutive patients died and submitted to autopsy in the same hospital during a 6 month period (from January to June 1983). The results show that: In the oldest (greater than 60 yrs) patients, the autopsy rate trend was significantly reduced from 1975 to 1983, whereas the hospital admissions and the mortality rate increased. In the youngest subjects (less than 60 yrs), the autopsy rate trend, the hospital admissions and the mortality rate did not significantly change from 1975 to 1983. In all the years considered, the autopsy rate was significantly reduced in the oldest class (p less than 0.001). The agreement between the clinical and pathological diagnosis was observed in 83% of cases in the less than 60 years class and in 63% of cases in the greater than 60 yrs class (p less than 0.001). The association of main disease with other diseases was significantly more frequent in the greater than 60 yrs class with respect to the less than 60 yrs class (p less than 0.01). It has been concluded that the autopsy, especially in the elderly, is absolutely necessary for a better quality control of the clinical diagnosis and of the medical care.

[Cardiac rupture: a not infrequent complication of acute myocardial infarction. Report of five cases (author's transl)].

Five cases of cardiac rupture (CR) in acute myocardial infarction (AMI) (four men and one woman aged between 49 and 86 years, mean 64) are described. The incidence of CR was 4,7% of 106 cases of AMI and 20,8% of causes of death. In all cases, pathologic observations well agreed with electrocardiographic site of infarction. All patients had ECG pattern of transmural AMI: postero-inferior (2 cases), anterior (1 case); none of them had myocardial infarction in the past. Two patients had systolic hypertension on admission, during and immediately before death, and 3 patients were normotensive during the whole course of illness. All patients had severe, prolonged and resistant to opiate therapy chest pain, which reexacerbated immediately before death in two cases. 4 patients died within 24 hours after the onset of symptoms. Terminal ECG pattern was similar in these four cases: sudden sinus bradycardia and/or idio-ventricular rhythm, with a progressive slowing of heart rate and changes of QRS patterns of "agonic" type, preceded electrical activity cessation. In one patient, who died at the seventh day of illness, ventricular fibrillation was observed. The AA. stress the importance of the early recognition of clinical findings suggesting an impeding CR in order to relieve cardiac tamponade with pericardiocentesis and to perform, as soon as possible, surgical treatment.
