Encephalopathy in severe SARS-CoV2 infection: Inflammatory or infectious?

Concerning the letter by Moriguchi et al., we describe our experience with a case of encephalopathy with and atypical damage on magnetic resonance imaging (MRI) in a patient with severe infection due to the SARS-CoV2 virus. A 56-year-old woman, without previous pathologies, developed cough, fever, and respiratory failure for five days, after returning from a 6-day trip to Venice. Chest radiography shows a large bilateral interstitial infiltrate. In the first 24 hours, she was admitted to the Intensive Care Unit (ICU) for severe respiratory failure and positive protein chain reaction-PCR in nasal exudate. She needed intubation for ten days. In the first 48 hours outside the ICU, she developed an acute confusional syndrome (hyperactive delirium). Neurological examination showed temporal-spatial disorientation and incoherent fluent speech. An electroencephalogram (EEG) showed generalized hypovoltaic activity. Cranial magnetic resonance imaging showed a bilateral and symmetrical increase in the supratentorial white matter's signal intensity, with a discrete thickening of both temporal lobes, with a slight increase in signal intensity and a sequence of normal diffusion. The lumbar puncture showed no changes (glucose 71 mg/dL, protein 30 mg/dL, 1 leukocyte). Within 72 hours of starting symptoms, she was neurologically asymptomatic. Our final diagnosis was an inflammatory encephalopathy related to a SARS-CoV2 infection.

Prevalence of the need for sodium intake restriction and the use of laxatives in palliative patients.

BACKGROUND: palliative patients usually have diseases that require a restriction of dietary sodium, although the prevalence of this requirement is unknown. Such conditions, combined with constipation, may mean that the use of laxatives with electrolytes should be avoided. OBJECTIVES: to ascertain the prevalence of the need to restrict sodium intake in palliative patients and to analyze the prevalence of constipation and the use of laxatives, including those containing sodium. METHOD: this was a multicenter retrospective, descriptive, cross-sectional, epidemiological study of both inpatients and outpatients over 18 years of age treated at the palliative care clinic (June 2015-March 2016). Demographic and anthropometric characteristics, diseases associated with dietary sodium restriction and treatments administered were recorded. RESULTS: the study sample consisted of 400 palliative patients, with a mean age of 77.8 ± 13.0 years and 52.2% were male. Of these, 68.3% were inpatients and 31.8% were outpatients. Comorbidities requiring low sodium or a sodium-free diet were found in 87.0% (95% CI: 83.3-90.0) of cases. Only 46.5% (95% CI: 41.5-51.5) of patients had been prescribed a low salt diet. It should be noted that 50.5% (95% CI: 45.5-55.5) of patients required a low sodium diet and suffered from constipation. Laxatives (polyethylene glycol or lactulose-rich products [PEG] with electrolytes in 54% of cases) were taken by 53.8% (95% CI: 48.7-58.7) of patients, 52.1% due to constipation and 42.3% as a prevention due to opioid treatment. CONCLUSIONS: a high proportion of the study cohort (87%) had some condition that required dietary sodium restriction and at least half the patients had constipation. The use of laxatives to treat or prevent constipation is common in palliative patients. A sodium-free laxative is therefore preferred in these patients.

Chagas' heart disease in Europe: an emergent disease?

Chagas' disease is caused by Trypanosoma Cruzi. It is considered as endemic in central and South America and is transmitted by several species of triatomic bedbug. However, there are other important ways of transmission between humans: vertical transmission and, above all, through blood products and transplants. In Chagas' disease, cardiac disturbances are the most important cause of morbidity, and they usually take place in the chronic stage. The symptoms are the same as in other dilated cardiomyopathies. The management of Chagas' heart disease may be even more difficult than other dilated cardiomyopathies. The increasing number of immigrants from endemic areas of Chagas' disease to developed countries would cause a radical increase in the incidence of this disease over the next years, however European cardiologists are unfamiliar with the disease. In this manuscript, we present our experience in order to stress the necessity of bearing Chagas' disease in mind as a possible cause of dilated cardiomyopathy in patients from endemic areas.
