The impact of COVID-19 on health status of home-dwelling elderly patients with dementia in East Lombardy, Italy: results from COVIDEM network.

BACKGROUND: COVID-19 outbreak has led to severe health burden in the elderly. Age, morbidity and dementia have been associated with adverse outcome. AIMS: To evaluate the impact of COVID-19 on health status in home-dwelling patients. METHODS: 848 home-dwelling outpatients with dementia contacted from April 27 to 30 and evaluated by a semi-structured interview to evaluate possible health complication due to COVID-19 from February 21 to April 30. Age, sex, education, clinical characteristics (including diagnosis of dementia) and flu vaccination history were obtained from previous medical records. Items regarding change in health status and outcome since the onset of the outbreak were collected. COVID-19 was diagnosed in patients who developed symptoms according to WHO criteria or tested positive at nasal/throat swab if hospitalized. Unplanned hospitalization, institutionalization and mortality were recorded. RESULTS: Patients were 79.7 years old (SD 7.1) and 63.1% were females. Ninety-five (11.2%) patients developed COVID-19-like symptoms. Non COVID-19 and COVID-19 patients differed for frequency of diabetes (18.5% vs. 37.9%, p < 0.001), COPD (7.3% vs. 18.9%, p < 0.001), and previous flu vaccination (56.7% vs. 37.9%, p < 0.001). Diabetes and COPD were positively associated with COVID-19, whereas higher dementia severity and flu vaccination showed an inverse association. Among COVID-19 patients, 42 (44.2%) were hospitalized while 32 (33.7%) died. Non COVID-19 patients' hospitalization and mortality rate were 1.9% and 1.2%, respectively. COVID-19 and COPD were significantly associated with the rate of mortality. DISCUSSION/CONCLUSIONS: A high proportion of adverse outcome related to COVID-19 was observed in home-dwelling elderly patients with dementia. Active monitoring though telehealth programs would be useful particularly for those at highest risk of developing COVID-19 and its adverse outcomes.

Assessment of the Incremental Diagnostic Value of Florbetapir F 18 Imaging in Patients With Cognitive Impairment: The Incremental Diagnostic Value of Amyloid PET With [18F]-Florbetapir (INDIA-FBP) Study.

IMPORTANCE: Cerebral amyloidosis is a key abnormality in Alzheimer disease (AD) and can be detected in vivo with positron emission tomography (PET) ligands. Although amyloid PET has clearly demonstrated analytical validity, its clinical utility is debated. OBJECTIVE: To evaluate the incremental diagnostic value of amyloid PET with florbetapir F 18 in addition to the routine clinical diagnostic assessment of patients evaluated for cognitive impairment. DESIGN, SETTING, AND PARTICIPANTS: The Incremental Diagnostic Value of Amyloid PET With [18F]-Florbetapir (INDIA-FBP) Study is a multicenter study involving 18 AD evaluation units from eastern Lombardy, Northern Italy, 228 consecutive adults with cognitive impairment were evaluated for AD and other causes of cognitive decline, with a prescan diagnostic confidence of AD between 15% and 85%. Participants underwent routine clinical and instrumental diagnostic assessment. A prescan diagnosis was made, diagnostic confidence was estimated, and drug treatment was provided. At the time of this workup, an amyloid PET/computed tomographic scan was performed, and the result was communicated to physicians after workup completion. Physicians were asked to review the diagnosis, diagnostic confidence, and treatment after the scan. The study was conducted from August 5, 2013, to December 31, 2014. MAIN OUTCOMES AND MEASURES: Primary outcomes were prescan to postscan changes of diagnosis, diagnostic confidence, and treatment. RESULTS: Of the 228 participants, 107 (46%) were male; mean (SD) age was 70.5 (7) years. Diagnostic change occurred in 46 patients (79%) having both a previous diagnosis of AD and an amyloid-negative scan (P < .001) and in 16 (53%) of those with non-AD diagnoses and an amyloid-positive scan (P < .001). Diagnostic confidence in AD diagnosis increased by 15.2% in amyloid-positive (P < .001; effect size Cohen d = 1.04) and decreased by 29.9% in amyloid-negative (P < .001; d = -1.19) scans. Acetylcholinesterase inhibitors and memantine hydrochloride were introduced in 61 (65.6%) patients with positive scan results who had not previously received those drugs, and the use of the drugs was discontinued in 6 (33.3%) patients with negative scan results who were receiving those drugs (P < .001). CONCLUSIONS AND RELEVANCE: Amyloid PET in addition to routine assessment in patients with cognitive impairment has a significant effect on diagnosis, diagnostic confidence, and drug treatment. The effect on health outcomes, such as morbidity and mortality, remains to be assessed.

Implementation of guidelines for type 2 diabetes mellitus in a post-acute geriatric setting.

BACKGROUND AND AIMS: Several health organizations have developed guidelines for type 2 diabetes mellitus, but it is known that population aging poses challenges to their application. We evaluated the reasons for not implementing guidelines for type 2 diabetes mellitus (DM) in patients admitted to a post-acute geriatric ward. METHODS: 209 patients (78.8+/-6.9 years old, female 72.7%) affected by DM, consecutively admitted in a Geriatric Evaluation and Rehabilitation Unit (GERU) between 2003 and 2005 for 32.2+/-11.5 days. The GERU geriatricians generated an algorithm for DM management following the guidelines proposed by the American Diabetes Association (2001) and the California Healthcare Foundation/American Geriatric Society (2003). The fit between medical choices and the guideline or the reasons for non-implementation were recorded on clinical charts. RESULTS: Guidelines were implemented in 82.3% of cases. The main reason for non-application was the physician's judgment of the patient's clinical condition. Subjects in the non-implementation group had worse functional status, their somatic comorbidity was more severe, and their clinical condition more unstable. They were also affected by more serious psychological and behavioral symptoms associated with dementia. In a multivariate logistic regression analysis, adjusting for age, gender, cognitive, functional status, and number of drugs, the burden of comorbidity was the only independent determinant for not implementing the guidelines (OR 2.27, 95% CI 1.36-3.81, p=0.002). CONCLUSIONS: although the guidelines for DM have previously been adapted to a geriatric setting, they are not applied in a significant percentage of old frail patients. Severe comorbidity is the main limitation for applying guidelines, but also polypharmacy, disability, cognitive impairment, and behavioral disturbances are factors taken into consideration before starting treatment of a very old patient affected by diabetes.

Sexual dysfunction in chronic hepatitis C virus patients treated with interferon alpha and ribavirin.

The effects on sexual behavior in patients with chronic hepatitis C treated with IFN alpha plus ribavirin is an understudied field. The aim of our study was to evaluate this treatment on sexual behavior. We enrolled 170 male patients affected by chronic hepatitis C that received three MIU intramuscular leukocyte Interferon alpha plus Ribavirin thrice a week for 12 months. We assessed IFN influence by using the responses to International Index of Erectile Function (IIEF). The baseline values of each IIEF score were compared to those obtained at the end of months 1, 3, 6, and 12 as well as at the end of the follow-up period. At the end of month 1, we detected a significant reduction of IIEF scores with respect to basal values, for all administered items. These values were similar to those found at the end of month 3 for almost all parameters, being increased in only the scores of erectile function. At the end of treatment, all scores appeared reincreased, but only mean score of erectile function appeared similar to pretreatment value. The organism adapts itself in someway to the action of cytokine. Psychological influence of IFN on the patients could justify the partial impairment of sensation linked to sexual behavior. Our study provided some more information in quantification and qualification of sexual disturbances related to IFN plus Ribavirin administration in the treatment of chronic hepatitis C.

Predictive role of single diseases and their combination on recovery of balance and gait in disabled elderly patients.

OBJECTIVES: In the elderly population, chronic diseases are common determinants of mobility limitations and comorbidity consistently shows a strong association with functional status. This study was designed to evaluate the role of single chronic diseases and of their combination on functional recovery after rehabilitative treatment in disabled elderly patients. DESIGN: With respect to the difference in magnitude of their disabling effect, diseases were classified into 2 groups: "more disabling" diseases (COPD, heart failure, peripheral artery diseases, diabetes, and not life-threatening cancer) and "less disabling" diseases (anemia, kidney, gastrointestinal, and liver diseases). SETTING: 35-bed Geriatric Evaluation and Rehabilitation Unit. PARTICIPANTS: We studied 710 patients (age 77.8 +/- 7.4 years, 76.2% females), consecutively admitted for stroke, Parkinson's disease, and osteoarthritis. MEASUREMENTS: A multidimensional evaluation for mobility (Tinetti-score), cognitive status (MMSE), and somatic health (Greenfield's Individual Disease Severity Index-IDS, Burden of diseases-BoD) was performed. Functional recovery was decided based on the Delta-Tinetti, which is the difference of the values between admission and discharge. RESULTS: We tested, in a multivariate regression model, the predictive role of single chronic conditions and of their combinations on functional recovery, after having adjusted for which diseases are direct causes of disability (stroke, Parkinson's disease, and osteoarthritis) and other potential predictors (age, sex, cognitive function, depressive symptoms, albumin, and c-reactive protein). A negative prediction of functional recovery was expressed by the "more disabling" diseases group. The determinants of poor recovery were characterized by the combination of "more disabling diseases" rather than single condition effects, independently by age, cognitive, and functional status on admission. CONCLUSION: Our study adds a new perspective about the role of COPD, heart failure, peripheral artery diseases, diabetes and not life-threatening cancer on functional recovery, emphasizing their combined impact in elderly people.

Intravenous immunoglobulin plus interferon-alpha in autoimmune hepatitis C.

BACKGROUND: Hepatitis C virus (HCV) may be associated with a variety of autoimmune phenomena causing a therapeutic dilemma for treatment with interferon-alpha (IFNalpha), which stimulates autoimmune symptoms, or with corticosteroids, which may lead to an increasing of viral load. To evaluate the possible role of intravenous immunoglobulins (IVIg) in the response of patients treated with IFNalpha, we administered IVIg plus IFNalpha and compared the results with a group of patients treated with IFNalpha alone. METHODS: Forty-two patients affected by chronic hepatitis C with probable autoimmune disease were eligible for this open-label, randomised study. All patients tested positively for anti-nuclear antibodies, anti-smooth muscle antibodies, anti-liver/kidney microsomal antibodies and anti-mitochondrial antibodies. Patients were randomly assigned to one of two groups: group A received IVIg at a dosage of 400 mg/kg each day for 5 days, and then 3 MUI of leucocyte IFNalpha three times a week, while group B received physiological solution followed by the administration of leucocyte IFNalpha three times a week at the same dosage for 6 months. Complete biochemical response was defined as a sustained normalisation of alanine aminotransferase levels, and complete virological response was defined as complete clearance of virus throughout the entire 6-month follow-up period. Immunological response was measured in terms of Autoimmune Hepatitis (AIH) score, while histological response was based on a reduction in histological activity index (HAI) score. RESULTS: Compared with patients receiving IFNalpha alone, a higher percentage of patients who received IFNalpha plus IVIg showed complete virological and histological responses (p = 0.04). More patients in the combination therapy group achieved biochemical and immunological responses, although the differences between the groups were not statistically significant at all time points. CONCLUSIONS: Exogenously added Ig might modulate the immune network at various points. We propose that the immunomodulating action of IVIg acts synergistically with IFNalpha, achieving a better response to IFN treatment in patients with chronic HCV associated with autoimmunity. Data obtained from this preliminary study indicate a positive prospective for the clinical use of gamma globulins in patients with a high probability of autoimmune disorders associated with HCV infection.

Efficacy of human recombinant erythropoietin plus IFN-alpha in patients affected by chronic hepatitis C.

Determination of serum iron levels in patients affected by chronic hepatitis C is considered fundamental for studying the response to interferon-alpha (IFN-alpha) treatment. IFN could induce anemia, which is promptly corrected by exogenous administration of recombinant human erythropoietin (rHuEPO). The aim of our study was to verify the possible beneficial effect of rHuEPO in patients affected by chronic hepatitis C and treated with IFN. Seventy consecutive patients (42 males and 28 females, mean age 46.4+/-5.2 years) affected by chronic hepatitis C were enrolled. In all patients, chronic hepatitis C was diagnosed on the basis of clinical and biological findings (alanine aminotransferase [ALT] serum levels at least 2-fold higher than normal values for at least 12 months and the presence of anti-HCV antibodies). All patients were negative for hepatitis B virus (HBV) infection, hepatitis D virus (HDV infection, and HIV infection. Statistical analysis was carried out using the Wilcoxon nonparametric sum rank test, the Spearman correlation rank test, and the Friedman ANOVA and Kendall coefficient of concordance. At the end of the treatment, our study series showed significant differences in serum levels of AST (p < 0.001), iron (p < 0.001), and ferritin (p < 0.001). At the end of the follow-up period, significant differences were seen in ALT, aspartate (AST), and iron ferritin and transferrin levels. All differences favored patients who received IFN-alpha and rHuEPO. We think that the depletion of circulating iron may improve the immune response impaired by iron accumulation in the liver. Our study confirms the important role played by iron in the response to IFN treatment, suggesting that the use of rHuEPO induces a better response to IFN in patients with chronic hepatitis C by activation of erythropoiesis.
