Prevalence of chronic pancreatitis: Results of a primary care physician-based population study.

Dig Liver Dis 2017 May 27;49(5):535-539. Epub 2016 Dec 27.

Azienda Sanitaria Locale Roma 5, Italy.

Background: Data on chronic pancreatitis prevalence are scanty and usually limited to hospital-based studies.

Aim: Investigating chronic pancreatitis prevalence in primary care.

Methods: Participating primary care physicians reported the prevalence of chronic pancreatitis among their registered patients, environmental factors and disease characteristics. The data were centrally reviewed and chronic pancreatitis cases defined according to M-ANNHEIM criteria for diagnosis and severity and TIGAR-O classification for etiology.

Results: Twenty-three primary care physicians participated in the study. According to their judgment, 51 of 36.401 patients had chronic pancreatitis. After reviewing each patient data, 11 turned out to have definite, 5 probable, 19 borderline and 16 uncertain disease. Prevalence was 30.2/100.000 for definite cases and 44.0/100.000 for definite plus probable cases. Of the 16 patients with definite/probable diagnosis, 8 were male, with mean age of 55.6 (±16.7). Four patients had alcoholic etiology, 5 post-acute/recurrent pancreatitis, 6 were deemed to be idiopathic. Four had pancreatic exocrine insufficiency, 10 were receiving pancreatic enzymes, and six had pain. Most patients had initial stage and non-severe disease.

Conclusions: This is the first study investigating the prevalence of chronic pancreatitis in primary care. Results suggest that the prevalence in this context is higher than in hospital-based studies, with specific features, possibly representing an earlier disease stage.

Dopamine receptor subtypes in the human coronary vessels of healthy subjects.

J Recept Signal Transduct Res 2011 Feb 12;31(1):33-8. Epub 2010 Aug 12.

Clinical Science (Policlinico Umberto I), "Sapienza" University, Rome, Italy.

Objective: Dopamine D(1)-D(5) receptors subtypes were studied in human coronary vessels of healthy subjects to assess their localization and their expression.

Methods: Samples of intraparenchymal and extraparenchymal branches of human coronary arteries and veins were harvested from four normal native hearts explanted from four young brain dead heart donors in case of orthoptic transplant, not carried out for technical reasons. In all the samples morphological, biochemical, immunochemical, and morphometrical studies were performed including quantitative analysis of images and evaluation of data.

Results: Microanatomical section showed healthy coronary vessels, which expressed all dopamine receptors (from D(1) to D(5)) with a different pattern of distribution between the different layers, in the intra and in the extraparenchymal branches.D(1) and D(5) (with a prevalence D(1) over D(5)) were distributed in the adventitia and to a lesser extent in the outer media but they were absent in arterioles, capillaries and venules. Endothelial and the middle layer showed D(2), D(3) and D(4) receptors, with a greater expression of D(2). Immunoblot analysis of dopamine monoclonal antibodies and dopamine receptors showed a different migration band for each receptor: D(1) (45 KDa); D(2) (43 KDa); D(3) (42 kDa); D(4) (40-42 KDa); D(5) (38-40 KDa)

Conclusion: These findings demonstrate the presence of all dopamine receptor subtypes in the wall of human coronary vessels of healthy subjects. Dopamine D(1) and D(2) receptor subtypes are the most expressed, suggesting their prominent role in the coronary vasoactivity.

Syncope caused by iatrogenic hyperkalemia.

J Cardiovasc Med (Hagerstown) 2009 Jan;10(1):72-4

Department of Emergency and Urgency, Sapienza University, Azienda Policlinico Umberto I, Rome, Italy.

Symptomatic bradycardia in the emergency department may have several causes (excessive vagal tone, drug toxicity, acute myocardial ischemia, sick sinus syndrome, heart block, and electrolyte imbalance); among these, hyperkalemia may develop as a complication of chronic medical treatment with angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers, and must be considered in the early approach to the bradyarrhythmic patient with possible electrocardiographic signs of hyperkalemia. We report a case of an 87-year-old woman with a clinical history of chronic angiotensin-receptor blocker consumption that led her to dangerous bradyarrhythmia, cardiogenic syncope, and risk of sudden cardiac death.

[Variation in the plasma concentration of B-type natriuretic peptide in emergent paroxysmal atrial fibrillation, in acute pulmonary embolism, in acute coronary syndrome and in dilated cardiomyopathy].

Ann Ital Med Int 2005 Jul-Sep;20(3):167-86

Dipartimento Emergenza-Accettazione/Osservazione EEA01 , Università degli Studi La Sapienza, Policlinico Umberto I, Roma.

Our research is based on the critical evaluation of plasma concentration variation of B-type natriuretic peptide (BNP)--in emergency--in paroxysmal atrial fibrillation, acute pulmonary edema, acute coronary syndrome and dilated cardiomyopathy. The aim of our research was to assess if the BNP concentration variation may be useful in the diagnosis and therapy. Peptide synthesis takes place mainly in the ventricular myocardium. We selected 102 patients: 27 control subjects, and 75 admitted to the emergency and reception department for dyspnea and/or precordialgia and/or palpitations. At the beginning they were considered as one group only, and then they were divided into groups according to the diagnosis: 20 with paroxysmal atrial fibrillation with reversion to sinus rhythm in the first week; 20 with acute pulmonary edema; 22 with acute coronary syndrome without electrocardiographic ST-segment changes; 13 with compensated dilated cardiomyopathy. Our research assessed that the BNP activation and secretion are evident especially in patients with heart failure and remains at the high level until the administration of an effective therapy and then they reach a balance with values higher than the standards, while in the paroxysmal atrial fibrillation and in acute coronary syndrome they rise and come back to the standard levels or even at lower levels after the disease solution. For this reason, BNP reiterated measurements allow to assess treatment efficacy, even at home, and to optimize the therapy. The main limit of BNP diagnostic role is in the need of knowing in advance the specific values for each patient. The BNP concentration evaluation in the acute phase is necessary to differentiate patients with dyspnea due to heart failure from those with pulmonary pathologies, while the BNP assessment in the acute coronary syndrome predicted exitus or heart failure manifestations.
