The Never-Ending Story of Hyponatremia: A Current Problem to Overcome.

Hyponatremia is a common complication in patients undergoing neurosurgery. If undiagnosed, it has a negative prognostic impact. The two dominant causes of refractory hyponatremia include syndrome of inappropriate ADH secretion (SIADH) and cerebral salt wasting syndrome (CSWS). Discrimination between the two types of disease is not always obvious. We present a case of undiagnosed chronic hyponatremia caused by CSWS after neurosurgery, which not only resulted in a longer hospital stay but also slowed the patient's postoperative recovery. Meticulous clinical evaluation and the performance of appropriate laboratory tests are therefore essential not only for decisive treatment, but also for the establishment of comprehensive diagnostic algorithms that allow timely diagnosis and decisive therapy. LEARNING POINTS: The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and cerebral salt-wasting syndrome (CSWS) are in general associated to refractory hyponatremia especially in patients with neurologic disorders.Extracellular fluid (ECF) assessment is the key to distinguish between SIADH and CSWS.Nevertheless, measurement of the ECF volume is not sufficient to determine the correct etiology and more established diagnostic algorithms are required.

Coffee and Microbiota: A Narrative Review.

Coffee is one of the most widely consumed beverages in the world, which has important repercussions on the health of the individual, mainly because of certain compounds it contains. Coffee consumption exerts significant influences on the entire body, including the gastrointestinal tract, where a central role is played by the gut microbiota. Dysbiosis in the gut microbiota is implicated in the occurrence of numerous diseases, and knowledge of the microbiota has proven to be of fundamental importance for the development of new therapeutic strategies. In this narrative review, we thoroughly investigated the link between coffee consumption and its effects on the gut microbiota and the ensuing consequences on human health. We have selected the most significant articles published on this very interesting link, with the aim of elucidating the latest evidence about the relationship between coffee consumption, its repercussions on the composition of the gut microbiota, and human health. Based on the various studies carried out in both humans and animal models, it has emerged that coffee consumption is associated with changes in the gut microbiota, although further research is needed to understand more about this link and the repercussions for the whole organism.

When Autoimmunity 'DRESSes up': A Case after Certolizumab Therapy.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is characterised by skin rash together with visceral organ involvement, lymphadenopathy, eosinophilia and atypical lymphocytosis. The syndrome is clinically heterogeneous, making diagnosis challenging. It has an annual incidence of 2 per 100,000 population and a mortality rate of 2-10%. We describe the first case of DRESS induced by certolizumab, a biologic disease-modifying antirheumatic drug (bioDMARD). LEARNING POINTS: Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is an uncommon and under-reported syndrome.Its recognition is critical for treatment, especially in the emergency setting where most patients first present.In the case of unexplained fever, lymphadenopathy, cutaneous rash and characteristic laboratory findings (e.g., eosinophilia), after infectious causes have been ruled out, clinicians should always keep DRESS in mind and consider possible recent intake of a triggering drug.

Gut Microbiota and Related Electronic Multisensorial System Changes in Subjects With Symptomatic Uncomplicated Diverticular Disease Undergoing Rifaximin Therapy.

Background: Intestinal dysbiosis might play a pathogenetic role in subjects with symptomatic uncomplicated diverticular disease (SUDD), but the effect of rifaximin therapy has been scantly explored with regard to gut microbiota variations in patients with SUDD. Aims: To verify to which extent rifaximin treatment affects the gut microbiota and whether an electronic multisensorial assessment of stools and breath has the potential for detecting these changes. Methods: Breath and stool samples were collected from consecutive patients with SUDD before and after a 7 days' therapy with rifaximin. Stool microbiota was assessed, and the electronic multisensorial assessment was carried out by means of the BIONOTE electronic (e-)tongue in stools and (e-)nose in breath. Results: Forty-three subjects (female 60%, median age 66 years) were included, and 20 (47%) reported clinical improvement after rifaximin therapy. Alpha and beta diversity of stool microbiota did not significantly change after treatment, while a significant variation of selected taxa was shown (i.e., Citrobacter, Coprococcus, Anaerotruncus, Blautia, Eggerthella lenta, Dehalobacterium, SMB53, and Haemophilus parainfluenzae). Overall, the electronic multisensorial system suboptimally mirrored microbiota changes, but it was able to efficiently predict patients' clinical improvement after rifaximin with accuracies ranging from 0.81 to 0.98. Conclusions: In patients with SUDD, rifaximin administration is associated with significant variation of selected taxa. While inaccurate in predicting gut microbiota change, an electronic multisensorial system, made up of e-tongue and e-nose, was able to predict clinical improvement, thus potentially qualifying as an easy and cheap tool to forecast subjects taking most likely benefit from rifaximin therapy.

Neuropsychiatric systemic lupus erythematosus: tools for the diagnosis.

Neurological involvement is considered to be a serious complication of systemic lupus erythematosus (SLE). Neuroimaging plays an important role in detecting neurological abnormalities in SLE patients. Conventional magnetic resonance imaging (cMRI) is generally the most valid neuroimaging technique for detecting alterations in the central and peripheral nervous systems. However it may occasionally fail in neuropsychiatric SLE (NPSLE). This is especially the case when the image is not very clear and may depend on the wide variety of neurological and psychiatric manifestations that define this disease. During the last twenty years, this has led to the testing of other radiological instruments, such as single photon emission computed tomography (SPECT), which is complementary to cMRI and seems to furnish additional information, and colour Doppler sonography, which provides minimal additional benefits. Our paper aims to provide a general overview of NPSLE, focusing particularly on the strengths and weaknesses of modern neuroimaging.

Olfactory deficit and hippocampal volume loss for early diagnosis of Alzheimer disease: a pilot study.

BACKGROUND: The aim of this pilot study was to verify the role of olfactory test and volumetric magnetic resonance imaging measure of hippocampus to predict conversion from mild cognitive impairment to Alzheimer disease (AD). MATERIALS AND METHODS: Eighteen patients with amnesic mild cognitive impairment, broadly defined, were followed at 12 months. Hypothesized baseline predictors for follow-up conversion to AD were olfactory deficit and hippocampal volumes loss. RESULTS: In the 1-year follow-up, 5 patients converted to AD. The 2 clinical predictors olfactory test and hippocampal volume loss showed the same sensitivity of 92.3% but the olfactory test showed a higher specificity than the hippocampal volume loss (75% vs. 60%). CONCLUSIONS: Our findings suggest the potential utility of olfactory test and hippocampal volume loss for early detection of AD.

Lung involvement in connective tissue diseases: a comprehensive review and a focus on rheumatoid arthritis.

The lungs are frequently involved in Connective Tissue Diseases (CTDs). Interstitial lung disease (ILD) is one of the most common pleuropulmonary manifestations that affects prognosis significantly. In practice, rheumatologists and other physicians tend to underestimate the impact of CTD-ILDs and diagnose respiratory impairment when it has reached an irreversible fibrotic stage. Early investigation, through clinical evidence, imaging and - in certain cases - lung biopsy, is therefore warranted in order to detect a possible ILD at a reversible initial inflammatory stage. In this review, we focus on lung injury during CTDs, with particular attention to ILDs, and examine their prevalence, clinical manifestations and histological patterns, as well as therapeutic approaches and known complications till date. Although several therapeutic agents have been approved, the best treatment is still not certain and additional trials are required, which demand more knowledge of pulmonary involvement in CTDs. Our central aim is therefore to document the impact that lung damage has on CTDs. We will mainly focus on Rheumatoid Arthritis (RA), which - unlike other rheumatic disorders - resembles Idiopathic Pulmonary Fibrosis (IPF) in numerous aspects.

Mediterranean dietary pattern adherence: associations with prediabetes, metabolic syndrome, and related microinflammation.

BACKGROUND: The adherence to the Mediterranean Diet (Med Diet) seems to reduce the incidence of metabolic syndrome. The present study aimed to explore whether the adherence to the overall Med Diet pattern and to specific Med Diet items is associated with the presence of metabolic syndrome, impaired fasting glucose (IFG), insulin resistance (IR), and microinflammation in subjects free of diabetes and cardiovascular diseases. MEASUREMENTS: Each patient underwent clinical assessment. Adherence to the Med Diet was measured by a previously validated 14-item questionnaire. Metabolic syndrome was defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria; IR was defined by homeostasis model assessment of insulin resistance (HOMA-IR); inflammation was assessed through a high-sensitivity C-reactive protein (hsCRP) assay. RESULTS: A total of 120 subjects (64.2% women, mean age 59.8±10.2 years) were enrolled at this study. Subjects with lower Med Diet pattern adherence exhibited higher occurrence of metabolic syndrome and all its components and higher HOMA-IR and hsCRP values (P for all <0.0001). Subjects with metabolic syndrome were less likely to consume olive oil (P=0.002) and vegetables (P=0.023). By multivariable analyses, the overall Med Diet score was found to be strongly and inversely associated with the presence of metabolic syndrome [B=-0.066; 95% confidence interval (CI) -0.105 to -0.028; P=0.001], IFG (B=-0.076; 95% CI -0.114 to -0.038; p<0.0001), high HOMA-IR (B=-0.071; 95% CI -0.108 to -0.034; P<0.0001) and high hsCRP (B=-0.082; 95% CI -0.125 to -0.045; P<0.0001). None of specific Med Diet items independently predicted metabolic syndrome, IFG, and high HOMA-IR. Instead, the consumption of white meat over red meat (B=-0.324; 95% CI -0.467 to -0.178; P<0.0001) was found to be inversely associated with increased hsCRP. CONCLUSIONS: The inverse associations between adherence to Med Diet and the prevalence of metabolic syndrome and prediabetes may be due more to the effects of the entire dietary pattern rather than to individual food components. Metabolic syndrome-related microinflammation may further be linked to specific Med Diet components.

Depressive symptoms in older people with metabolic syndrome: is there a relationship with inflammation?

OBJECTIVE: To investigate if there is a higher prevalence of depressive symptoms in older people with metabolic syndrome (MetS) compared with those without and whether dedpressive symptoms are independently associated to MetS and its single components and to the inflammatory markers. METHODS: Physical parameters, standard blood analytes, high sensitivity C-reactive protein (hsCRP) and erythrocyte sedimentation rate (ESR) were assessed. Fifteen-item Geriatric Depression Scale and mini mental state examination (MMSE) were administered. RESULTS: One hundred thirty-three subjects were enrolled. MetS patients (57) exhibited higher prevalence of depressive symptoms (p < 0.0001), worse cognitive function (p < 0.0001), and higher levels of ESR and hsCRP were higher (p < 0.0001). The univariate analysis showed a linear strong correlation of depressive symptoms (p < 0.0001) with the MMSE score (r = -0.422), body mass index (r = 0.414), MetS (r = 0.582), number of MetS components (r = 0.663), fasting blood glucose (r = 0.565), ESR (r = 0.565), hsCRP (r = 0.745), central obesity (r = 0.269; p = 0.002), and high-density lipoprotein cholesterol (r = -0.241; p = 0.005). However, the multivariate analysis showed that only age (B = -0.093; p = 0.032), MetS (B = 1.446; p = 0.025), fasting blood glucose (B = 0.039; p = 0.005), and hsCRP (B = 7.649; p < 0.0001) were independently associated with depressive symptoms. CONCLUSIONS: MetS and inflammation are independently associated with depressive symptoms in older people. Inflammation may explain cognitive decline too. Further investigations are needed to better understand the direction of these associations and to determine whether these can be reversible.

Impact of combined therapy with alpha-lipoic and ursodeoxycolic acid on nonalcoholic fatty liver disease: double-blind, randomized clinical trial of efficacy and safety.

BACKGROUND AND PURPOSE: Nonalcoholic fatty liver disease (NAFLD) is one of the causes of a fatty liver, occurring when fat is deposited (steatosis) in the liver not due to excessive alcohol use. It is related to insulin resistance and the metabolic syndrome. The purpose of the present study was to evaluate the impact of combination therapy with alpha-lipoic acid (ALA) and ursodeoxycholic acid (UDCA) on NAFLD. METHODS: Alpha-lipoic acid 400 mg/day plus UDCA 300 mg/day (ALAUDCA) was investigated in patients over a period of 12 months using a randomized, placebo (PLA)-controlled study with four parallel groups. Serum concentration of gamma-glutamyl transpeptidase (GGT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin and platelets (PLT) were measured at the beginning and at the end of the treatment. Moreover, the AST/ALT ratio and the NAFLD fibrosis score were examined. RESULTS: A total of 120 patients were randomly assigned to the four groups. ALA and UDCA were safe and well tolerated in the oral daily administration only. AST, ALT, GGT (p < 0.001) showed a significant difference between ALAUDCA and other three groups. Besides, NAFLD fibrosis score underlined a significant reduction (p < 0.04) in the ALAUDCA group, while AST/ALT ratio presented a moderate decline (p > 0.05). CONCLUSION: ALAUDCA therapy reduced AST, ALT, GGT values and improved NAFLD fibrosis score and AST/ALT ratio, especially in patients who were on a hypocaloric diet. These findings will be useful in patient selection in future clinical trials with ALAUDCA in long-term studies.

[Predictors of liver fibrosis in patients with non-alcoholic fatty liver disease. The role of metabolic syndrome, insulin-resistance and inflammation]. / Predittori di fibrosi epatica in pazienti con steatosi epatica non-alcolica. Il ruolo della sindrome metabolica, dell'insulino-resistenza e dell'infiammazione.

INTRODUCTION: NAFLD (non-alcoholic fatty liver disease) reaches an high prevalence in the general population, and it is closely related to metabolic syndrome (MetS). The entity of metabolic abnormalities and the chronic inflammation seem to play a main role in the development of liver fibrosis. The aim of our study is to determine whether subjects with NAFLD and MetS have higher liver fibrosis degree when compared with NAFLD subjects without MetS, and to investigate the relations between fibrosis, MetS and its single components and inflammation. MATERIALS AND METHODS: We considered 24 patients with NAFLD. Those who had viral- and alcohol- related liver disease were excluded. MetS was diagnosed according to NCEP ATP III criteria; inflammatory status was determined through C-reactive protein (PCR) assay. The peripheral insulin-resistance was assessed by calculating HOMA ir. Liver fibrosis was measured by transient elastography (Fibroscan®). RESULTS: Subjects with MetS had higher HOMA ir, PCR and Fibroscan® score (log value: 0.92±0.24 KPa vs 0.73±0.2 KPa; p=0.047). The linear correlation analysis showed that Fibroscan® score was related to MetS, number of MetS components, waist circumference, HOMA ir and PCR. However the multivariate regression analysis showed that only HOMA ir (B=0.077; 95%CI: -0.002- 0.157; p=0.05) and PCR (B=0.152; 95% CI: 0.006 - 0.299; p=0.006) were independent predictors of higher Fibroscan® score. CONCLUSION: MetS is associated to higher liver fibrosis degree in subjects with NAFLD. The insulin-resistance and inflammation seem to be the main determinants.

[Hepatic steato-fibrosis and non-alcoholic liver disease in elderly]. / Steato-fibrosi del fegato e malattia non-alcolica del fegato nel paziente anziano.

The critical role of the hepatic stellate cells in pathogenesis and evolution of hepatic fibrosis is stressed. The authors, also, illustrate the most recent acquisitions about morphological and bioumoral aspects of complex sinusoidal-Disse space-stellate cells and their importance for the risk of evolution towards non-alcoholic liver disease.

[Cardiac arrythmias in the elderly]. / Aritmie cardiache in età geriatrica.

The prescription of antiarrhythmic therapy in the elderly depends on the characteristics of clinical symptoms and on the potential morbidity and mortality. Some cardiac arrhythmias may cause bothersome symptoms but do not affect the long-term prognosis. However, other dysrhythmias with mild or no symptoms may be associated with a poor prognosis.

[Adapted physical activity: the role in secondary prevention of the osteoporosis]. / Attività motoria adattata nella prevenzione secondaria dell'osteoporosi.

An active lifestyle represents a significant factor in prevention of osteoporosis. Evidences on multifactorial etiology allowed to develop a plan for risk evaluation and for an integrated screening approach. Adapted physical activity plays a relevant role in secondary prevention, also when performed in swimming pools.

Empirical antibiotic therapy (ABT) of lower respiratory tract infections (LRTI) in the elderly: application of artificial neural network (ANN). Preliminary results.

LRTI are among the most common diseases in developed countries, including chronic obstructive pulmonary disease (COPD), one of the most frequent conditions. Their treatment in general practice is often unsuccessful and this increases hospital admissions. We know, bacterial infections in the elderly show a higher morbidity and mortality, either for more severe symptoms, than in younger adults, or because the causing agent often remains unknown. The need for a quick initiation of ABT often requires to chose on empirical grounds. To date there are no official guidelines for empirical ABT of COPD exacerbations, but only heterogeneous and often conflicting recommendations exist. The aim of our study was to identify a tool to guide the choice of the most effective empirical ABT when symptoms are acute and bacteriological tests cannot be performed. We used an ANN to study 117 patients aged between 55 and 97 years (mean 81.5 ± 8.7 years) (± S.D.), admitted with a diagnosis of pneumonia, COPD exacerbation or pneumonia with respiratory failure. We registered symptoms at onset and some individual variables such as age, sex, risk factors, comorbidity, current drug therapies. Then the ANN was applied to choose ABT in 20 patients versus 20 subjects whose therapy was chosen by the physicians, comparing these groups for therapy's efficacy, mean durations of therapy and hospitalization (H). In the learning phase, the ANN could predict the resolution index 99.05% of the time (i.e., 104 times) with a ± S.D. = 0.23. After the training, during the test phase, the network predicted the resolution index 91.67% of the time (i.e., 11 times) with a ± S.D. = 0.54, thus proving the validity of the relations identified during the learning phase. Preliminary results of the application of our tool, show the ANN allowed us to greatly reduce the duration of the ABT and subsequently of the H. Based on preliminary results, we assume that the use of ANN can make a valuable contribution in the choice of empirical ABT in the course of acute lung diseases in elderly.

This is a case of 89 years old patient suffering by chronic obstructive pulmonary disease and affected by acute respiratory failure characterized by hypoxemia and hipercapnia. It is interesting because, comparing oxygen therapy and non invasive ventilation, the best results were reached with the last technique, in an elder patient.

[Vascular depression in the elderly. Does inflammation play a role?]. / La depressione vascolare nell'anziano. Quale ruolo per l'infiammazione?

Vascular depression in the elderly. Does inflammation play a role?Depression is the most common comorbidity in the elderly, and it is a major determinant of disability. The late-onset depression in highly associated to cardiovascular disease. Depressive symptoms may follow vascular brain damage, especially when mood regulating areas are affected. However depression is strongly associated to vascular disease even when there is no manifest brain damage. Recently great attention has been given to chronic inflammation, both related to depression and vascular disease. Both experimental and clinical evidence shows that a rise in the concentrations of proinflammatory cytokines and glucocorticoids in depressed patients is associated with defect in serotonergic function. Chronic inflammation may underlie many forms of depression associated with vascular disease and metabolic syndrome. The importance of the inflammation hypothesis of depression lies is that psychotropic drugs may have central anti-inflammatory action, and that new generation of central anti-inflammatory drugs may be useful in depression treatment.

[Prevalence of depression in a geriatric population with metabolic syndrome]. / Prevalenza della depressione in una popolazione geriatrica con sindrome metabolica.

Metabolic Syndrome (Metabolic Syndrome, MS) is associated with many other diseases in the elderly. We have studied a possible correlation between this disorder and depression in a Geriatric Centre. The study was conducted on a random sample of 30 geriatric patients, then divided into 2 groups according to clinical and instrumental diagnostic investigations: 15 patients affected MS according to the criteria of NCEP ATP III, and 15 controls without MS. Then it's administered the Geriatric Depression Scale (GDS). Elaboration of the results it appears statistically significant correlation (t=2.05, p=0.0495) between MS and depression in the elderly.
