Defective spleen function in autoimmune gastrointestinal disorders

Defective spleen function increases susceptibility to bacterial infections which can be prevented by vaccine prophylaxis. Splenic hypofunction can be found in a number of autoimmune disorders; however, no data are available regarding autoimmune atrophic gastritis (AAG), autoimmune enteropathy (AIE) and autoimmune liver disease (AILD). Peripheral blood samples from patients with AAG (n = 40), AIE (n = 3) and AILD (n = 40) were collected. Patients affected by autoimmune disorders already known to be associated with splenic hypofunction, i.e. coeliac disease (CD) and ulcerative colitis (UC), were included as disease controls, while splenectomised patients and healthy subjects were evaluated as positive and negative controls, respectively. Counting of erythrocytes with membrane abnormalities, i.e. pitted red cells, was used as an indicator of spleen function (normal upper limit 4%). Defective splenic function was observed in 22 of the 40 patients with AAG (55.0%), in two of the three patients with AIE (66.6%) and in 35 of the 40 patients with AILD (87.5%). As expected, in untreated CD, refractory CD and UC there was a high prevalence of hyposplenism (43.7%, 88.2% and 54.4%, respectively). Due to the high prevalence of splenic hypofunction, patients with AAG, AILD and AIE should undergo pitted red cell evaluation and, if hyposplenic, they should be candidate to vaccine prophylaxis against encapsulated bacteria

Corneal Involvement In Primary Biliary Cirrhosis : An In Vivo Confocal Microscopy Study

Purpose:To investigate the corneal involvement in Primary Biliary Cirrhosis (PBC), a slowly progressive cholestatic liver disease of autoimmune etiology. Methods:Seven female patients affected by PBC underwent a slit-lamp biomicroscopy of the anterior segment with and without Goldmann's three-mirror contact lens, and laser scanning confocal microscopy (LSCM, Heidelberg Engineering Germany). LSCM images were acquired and analyzed for all layers of central and peripheral cornea (four quadrants). Results:All patients had normal findings both at slit-lamp biomicroscopy and at gonioscopy. Peculiar findings were shown at LSCM: all patients showed keratocytes activation (Figure 1); sub-basal nerve fibers with beadlike structure (Figure 2) were found in six patients (86%); four subjects (57%) had hyper-reflective stromal macro-deposits (Figure 2). No deposits suggestive for copper deposition were detected at the level of Descemet\u2019s membrane. Conclusions:To the best of our knowledge this is the first confocal microscopy study on PBC patients. LSCM could show that subclinical corneal inflammation is a very common finding also in ophthalmoscopically normal patients affected by this autoimmune disease

Validation of the Italian translation of the perceived stigma scale and resilience assessment in inflammatory bowel disease patients

BACKGROUND Stigmatization is the separation of an individual from a group due to aspects that make them different. Resilience may in turn influence the perception of stigma. Patients with inflammatory bowel disease (IBD) are susceptible to stigma, although data are very limited. AIM To validate an Italian translation of the IBD perceived stigma scale (PSS) in relation to patients’ resilience. METHODS Consecutive IBD outpatients were prospectively enrolled (December 2018-September 2019) in an Italian, tertiary referral, IBD center. Clinical and demographic data were collected. Stigma and resilience were evaluated through the IBD-PSS and the 25-item Connor-Davidson Resilience Scale, respectively. The International Quality of Life Assessment Project approach was followed to translate the IBD-PSS into Italian and to establish data quality. Higher scores represent greater perceived stigma and resilience. Multivariable analysis for factors associated with greater stigma was computed. RESULTS Overall, 126 IBD patients (mean age 46.1 ± 16.9) were enrolled. The International Quality of Life Assessment criteria for acceptable psychometric properties of the scale were satisfied, with optimal data completeness. There was no ceiling effect, whilst floor effect was present (7.1%). The discriminant validity and the internal consistency reliability were good (Cronbach alpha = 0.87). The overall internal consistency was 95%, and the test-retest reliability was excellent 0.996. The median PSS score was 0.45 (0.20-0.85). Resilience negatively correlated with perceived stigma (Spearman’s correlation = -0.18, 95% confidence intervals: -0.42-0.08, P = 0.03). CONCLUSION We herein validated the Italian translation of the PSS scale, also demonstrating that resilience negatively impacts perceived stigma

Impact of COVID-19 on liver function: results from an internal medicine unit in Northern Italy

Little is known regarding coronavirus disease 2019 (COVID-19) clinical spectrum in non-Asian populations. We herein describe the impact of COVID-19 on liver function in 100 COVID-19 consecutive patients (median age 70 years, range 25–97; 79 males) who were admitted to our internal medicine unit in March 2020. We retrospectively assessed liver function tests, taking into account demographic characteristics and clinical outcome. A patient was considered as having liver injury when alanine aminotransferase (ALT) was > 50 mU/ml, gamma-glutamyl transpeptidase (GGT) > 50 mU/ml, or total bilirubin > 1.1 mg/dl. Spearman correlation coefficient for laboratory data and bivariable analysis for mortality and/or need for intensive care were assessed. A minority of patients (18.6%) were obese, and most patients were non- or moderate-drinkers (88.5%). Liver function tests were altered in 62.4% of patients, and improved during follow-up. None of the seven patients with known chronic liver disease had liver decompensation. Only one patient developed acute liver failure. In patients with altered liver function tests, PaO2/FiO2 < 200 was associated with greater mortality and need for intensive care (HR 2.34, 95% CI 1.07–5.11, p = 0.033). To conclude, a high prevalence of altered liver function tests was noticed in Italian patients with COVID-19, and this was associated with worse outcomes when developing severe acute respiratory distress syndrome

Correction to: Anemia in patients with Covid-19: pathogenesis and clinical significance (Clinical and Experimental Medicine, (2021), 10.1007/s10238-020-00679-4)

The original version of this article unfortunately contained a mistake. The correct information is given below. The co-authorship of the members of ‘‘Internal Medicine Covid-19 Collaborators” was inadvertently not clearly indicated. The names of these members should have been clearly linked to the author line of the article, to ensure that the article can be found under each of their names in PubMed and other databases. In order to rectify this situation, this erratum provides a corrected author line, found above, that includes the names of the members of ‘‘Internal Medicine Covid-19 Collaborators”. The given name and family name of the second author was incorrectly tagged in the xml data, therefore it is abbreviated wrongly as ‘‘de Andreis FB’’. The correct given name is Federica and family name is Borrelli de Andreis. The original article has been corrected

Anemia in patients with Covid-19: pathogenesis and clinical significance

COVID-19 patients typically present with lower airway disease, although involvement of other organ systems is usually the rule. Hematological manifestations such as thrombocytopenia and reduced lymphocyte and eosinophil numbers are highly prevalent in COVID-19 and have prognostic significance. Few data, however, are available about the prevalence and significance of anemia in COVID-19. In an observational study, we investigated the prevalence, pathogenesis and clinical significance of anemia among 206 patients with COVID-19 at the time of their hospitalization in an Internal Medicine unit. The prevalence of anemia was 61% in COVID-19, compared with 45% in a control group of 71 patients with clinical and laboratory findings suggestive of COVID-19, but nasopharyngeal swab tests negative for SARS-CoV-2 RNA (p = 0.022). Mortality was higher in SARS-CoV-2 positive patients. In COVID-19, females had lower hemoglobin concentration than males and a higher prevalence of moderate/severe anemia (25% versus 13%, p = 0.032). In most cases, anemia was mild and due to inflammation, sometimes associated with iron and/or vitamin deficiencies. Determinants of hemoglobin concentration included: erythrocyte sedimentation rate, serum cholinesterase, ferritin and protein concentrations and number of chronic diseases affecting each patient. Hemoglobin concentration was not related to overall survival that was, on the contrary, influenced by red blood cell distribution width, age, lactate dehydrogenase and the ratio of arterial partial oxygen pressure to inspired oxygen fraction. In conclusion, our results highlight anemia as a common manifestation in COVID-19. Although anemia does not directly influence mortality, it usually affects elderly, frail patients and can negatively influence their quality of life
