Short-Term Consequences of SARS-CoV-2-Related Pneumonia: A Follow Up Study.

The aim of the study was to assess the short-term consequences of SARS-CoV-2-related pneumonia, also in relation to radiologic/laboratory/clinical indices of risk at baseline. This prospective follow-up cohort study included 94 patients with confirmed COVID-19 admitted to a medical ward at the Montichiari Hospital, Brescia, Italy from February 28th to April 30th, 2020. Patients had COVID-19 related pneumonia with respiratory failure. Ninety-four patients out of 193 survivors accepted to be re-evaluated after discharge, on average after 4 months. In » of the patients an evidence of pulmonary fibrosis was detected, as indicated by an altered diffusing capacity of the lung for carbon monoxide (DLCO); in 6-7% of patients the alteration was classified as of moderate/severe degree. We also evaluated quality of life thorough a structured questionnaire: 52% of the patients still lamented fatigue, 36% effort dyspnea, 10% anorexia, 14% dysgeusia or anosmia, 31% insomnia and 21% anxiety. Finally, we evaluated three prognostic indices (the Brixia radiologic score, the Charlson Comorbidity Index and the 4C mortality score) in terms of prediction of the clinical consequences of the disease. All of them significantly predicted the extent of short-term lung involvement. In conclusion, our study demonstrated that SARS-CoV-2-related pneumonia is associated to relevant short-term clinical consequences, both in terms of persistence of symptoms and in terms of impairment of DLCO (indicator of a possible development of pulmonary fibrosis); some severity indices of the disease may predict short-term clinical outcome. Further studies are needed to ascertain whether such manifestations may persist long-term.

Prognostic factors and predictors of outcome in patients with COVID-19 and related pneumonia: a retrospective cohort study.

The aim of the present study was to simultaneously assess several potential predictors of outcome (co-morbidity, previous and in-hospital treatment, radiologic Brixia score) in patients with COVID-19. This retrospective cohort study included 258 consecutive patients with confirmed COVID-19 admitted to a medical ward at Montichiari Hospital, Brescia, Italy from February 28th to April 30rd, 2020. Patients had SARS-CoV-2 related pneumonia with respiratory failure, and were treated with hydroxychloroquine and lopinavir plus ritonavir. In some patients, additional treatment with tocilizumab, dexamethasone and enoxaparin was adopted. Outcomes (death or recovery) were assessed at the end of the discharge period or at the end of the follow-up (August 2020). During hospitalization, 59 patients died, while 6 died after discharge. The following variables were demonstrated to be associated with a worse prognosis: Radiologic Brixia score higher than 8, presence at baseline of hypertension, diabetes, chronic obstructive pulmonary disease, heart disease, cancer, previous treatment with ACE-inhibitors or anti-platelet drugs. Anticoagulant treatment during hospital admission with enoxaparin at a dose higher than 4000 U once daily was associated with a better prognosis. In conclusion, our study demonstrates that some co-morbidities and cardiovascular risk factors may affect prognosis. The radiologic Brixia score may be a useful tool to stratify the risk of death at baseline. Anticoagulant treatment with enoxaparin might be associated to a clinical benefit in terms of survival in patients with COVID-19.

Myocardial ultrasound tissue characterization in patients with chronic renal failure.

The objective of this study was to detect ultrastructural changes in myocardium related to collagen content by ultrasound tissue characterization in patients with chronic kidney disease (CKD) and in uncomplicated hypertensive control subjects. In 25 hemodialysis (HD) patients, in 25 patients with moderate to severe chronic renal failure (CRF), and in 10 patients with essential hypertension (EH) and normal renal function matched for age, BP, and left ventricular mass index, left ventricular anatomy and function were evaluated by conventional echocardiography, and integrated backscatter signal (IBS) was analyzed by acoustic densitometry. IBS mean reflectivity increased from 48% in patients with EH to 56% in patients with CRF to 62% in HD patients (ANOVA P < 0.01). IBS mean cyclic variation was progressively increased from 4.35 +/- 1.2 dB in HD patients to 5.27 +/- 0.90 in patients with CRF to 6.50 +/- 1.6 dB in patients with EH (ANOVA P < 0.01). At multivariate analysis, IBS mean reflectivity was positively related to age and serum creatinine (beta 0.351, P = 0.036; and beta = 0.408, P = 0.016, respectively). IBS mean cyclic variation was inversely related to age and serum creatinine (beta = -0.274, P = 0.025; and beta = -0.262, P = 0.025, respectively) and positively related to left ventricular midwall fractional shortening and transmitral E/A ratio (beta = 0.269, P < 0.05; and beta = 0.314, P < 0.001, respectively). The data support the hypothesis that interstitial collagen deposition may appear early in the course of CKD and suggest that acoustic densitometry may represent a useful tool for the assessment of myocardial tissue changes in patients with CKD.

Inappropriate left ventricular mass changes during treatment adversely affects cardiovascular prognosis in hypertensive patients.

Inappropriate left ventricular mass (LVM; ie, the value of LVM exceeding individual needs to compensate hemodynamic load) predicts the risk of cardiovascular (CV) events, independent of risk factors, either in the presence or in the absence of traditionally defined LV hypertrophy. The relation between changes in appropriateness of LVM during antihypertensive treatment and subsequent prognosis was evaluated in 436 prospectively identified uncomplicated hypertensive subjects, with a baseline and follow-up standard clinical evaluation, laboratory examinations, and echocardiogram (last examination: 6+/-3 years apart), followed for additional 4.5+/-2.5 years. The appropriateness of LVM to cardiac workload was calculated by the ratio of observed LVM to the value predicted for individual sex, height, and stroke work at rest. At baseline, low or appropriate LVM (

Headache: Prevalence and relationship with office or ambulatory blood pressure in a general population sample (the Vobarno Study).

UNLABELLED: The association of headache and arterial hypertension is still controversial, although headache is usually considered a symptom of hypertension. The aim of this study is to evaluate the prevalence of headache in a general population sample and the relationship with arterial hypertension, as diagnosed by office measurements and ambulatory monitoring of blood pressure (BP). PATIENTS AND METHODS: In the randomized sample of the Vobarno population, 301 subjects (126 males, 175 females, age range 35-50 years) underwent a structured standardized headache questionnaire, office and 24-h ambulatory BP monitoring. RESULTS: Prevalence of lifetime headache and of migraine was greater in females than in males. Office and 24-h BP values did not differ between subjects without headache and subjects with headache. No differences in headache prevalence (58% vs 55%), migraine prevalence (32% vs 28%) and use of analgesic drugs in the presence of headache (82% vs 78%) were observed between hypertensive patients (93.5% newly diagnosed, 6.5% treated) and normotensive subjects. CONCLUSIONS: In a general population sample, hypertension (diagnosed by office and/or 24-h BP) is not associated with headache.

Left ventricular concentric geometry during treatment adversely affects cardiovascular prognosis in hypertensive patients.

Left ventricular (LV) mass and geometry predict risk for cardiovascular events in hypertension. Regression of LV hypertrophy (LVH) may imply an important prognostic significance. The relation between changes in LV geometry during antihypertensive treatment and subsequent prognosis has not yet been determined. A total of 436 prospectively identified uncomplicated hypertensive subjects with a baseline and follow-up echocardiogram (last examination 72+/-38 months apart) were followed for an additional 42+/-16 months. Their family doctor gave antihypertensive treatment. After the last follow-up echocardiogram, a first cardiovascular event occurred in 71 patients. Persistence of LVH from baseline to follow-up was confirmed as an independent predictor of cardiovascular events. Cardiovascular morbidity and mortality were significantly greater in patients with concentric (relative wall thickness > or =0.44) than in those with eccentric geometry (relative wall thickness <0.44) in patients presenting with LVH (P=0.002) and in those without LVH (P=0.002) at the follow-up echocardiogram. The incidence of cardiovascular events progressively increased from the first to the third tertile of LV mass index at follow-up (partition values 91 and 117 g/m2), but for a similar value of LV mass index it was significantly greater in those with concentric geometry (OR: 4.07; 95% CI: 1.49 to 11.14; P=0.004 in the second tertile; OR: 3.45; 95% CI: 1.62 to 7.32; P=0.001 in the third tertile; P<0.0001 in concentric versus eccentric geometry). Persistence or development of concentric geometry during follow-up may have additional prognostic significance in hypertensive patients with and without LVH.
