Prevalence and clinical course of hepatitis delta infection in Greece: a 13-year prospective study.

BACKGROUND & AIMS: Hepatitis D virus (HDV) has decreased in Europe, but recent reports indicate a rising trend. We report the epidemiological changes, clinical progress, and effect of treatment on the natural course of HDV infection in Greece during the last 13 years. METHODS: Prospective data were extracted from the HepNet.Greece Cohort-Study. RESULTS: Since 1997, 4673 chronic HBV (CHB) cases (4527 adults, 146 children) have been followed prospectively. Two thousand one hundred thirty-seven patients were tested for anti-HDV [101 (4.7%) positive]. Anti-HDV testing in Greece decreased significantly (57.0% before 2003, 35.3% thereafter; p<0.001). Anti-HDV prevalence among HBsAg-positives was 4.2%; lower in native Greeks (2.8%) than in immigrants (7.5%) or in children (15.3%; p<0.001). Within 2.3 years of follow-up, HDV occurred in 11/2047 HBsAg-positive patients (2.2 new delta-infected adults and 8.7 children per 1000 HBsAg-positive annually). HDV-positive compared to CHB adults were younger (p=0.035) and had more active and advanced disease at baseline, as indicated by laboratory indices and the higher prevalence of cirrhosis at younger age. During a 4.2-year median observation, significantly more anti-HDV-positive than CHB adults developed a liver-related first event (20.0% vs. 8.5%, p Log-rank=0.014).Treatment was received by 46/90 (51.1%) patients, 40 of them interferon-based. In multivariable analysis, interferon significantly decreased disease progression in HDV-positive patients [HR=0.14 (95% CI: 0.02-0.86; p=0.033)]. CONCLUSIONS: In Greece, HDV serology is currently tested in only one-third of HBsAg-positive patients. HDV prevalence is lower in native Greeks compared to immigrants, who may contribute >50% of the HDV infection burden in Greece. Data show that HDV infection is a rapidly progressive disease, but interferon-based treatment may alter its course.

Systemic sclerosis associated with generalized vasculitis and hypopituitarism.

Systemic sclerosis (SSc) is a progressively evolving multisystemic disorder of unknown etiology. Beyond skin, several other organs can also be affected with a severity of involvement that is often heterogeneous. We describe a 53-year-old female patient who was admitted urgently to the hospital almost collapsed, because of numerous bleeding deep skin ulcers, located all over the body. Clinical findings and autoantibody screening were typical of SSc. Moreover, both histopathology and immunofluorescence findings were compatible with scleroderma and vasculitis as well. In addition, pituitary hormone investigation revealed severely damaged function of the gland. We assume that severe skin ulceration and serious hypopituitarism were both implications of underlying SSc-associated vasculitis. To the best of our knowledge, these peculiar clinical manifestations have not been described in the international literature to date.

Comparison of monotherapy versus combination antihypertensive therapy in elderly patients with essential hypertension.

Authors sought to compare the efficacy of monotherapy versus combination antihypertensive therapy in elderly patients. Patients in this study, aged 65 to 85 years, were divided into 4 groups and entered an 8-week treatment period. First group: 22 patients, amlodipine 5 mg/d increasing to 10 mg; second: 20 patients, eprosartan 600 mg/d increasing to 600 mg twice a day; third: 21 patients, amlodipine 5 mg/d and indapamide 2.5 mg/d, increasing amlodipine to 10 mg/d; fourth: 23 patients, imidapril 10 mg/d and indapamide 2.5 mg/d, imidapril doubled to 20 mg/d. A greater drop in systolic and in diastolic blood pressure was obtained by combination of amlodipine and indapamide compared with amlodipine or eprosartan monotherapy. Imidapril and indapamide showed similar efficacy compared with eprosartan monotherapy but not with amlodipine monotherapy. Amlodipine and indapamide appeared more effective than imidapril and indapamide in diastolic blood pressure. Combination treatment with amlodipine and indapamide or imidapril and indapamide effectively reduces blood pressure in elderly patients with essential hypertension.

Isolated primary cardiac amyloidosis associated with porokeratosis of Mibelli.

In this report we briefly describe a 54-year-old woman who was referred to our institution for evaluation and management of newly diagnosed congestive heart failure associated with a skin rash. Detailed investigations revealed the presence of restrictive cardiomyopathy due to isolated primary cardiac amyloidosis as well as the presence of a skin disease named 'porokeratosis of Mibellli'. Interestingly, porokeratotic lesions rarely have been associated with localized cutaneous amyloidosis. Presumably, porokeratosis induces secondary dermal amyloid deposition by a yet unknown mechanism. This is the first case of primary amyloidosis associated with porokeratosis reported in the literature.

Neurolisteriosis mimicking herpes simplex encephalitis in an immunocompromized patient.

Brain MRI was performed in an immunocompromized febrile and lethargic patient, revealing an asymmetric bilateral temporal lobe involvement, strongly suggestive of herpetic encephalitis. Nevertheless, PCR in CSF for Listeria monocytogens was positive. This case implies that Listeria might be considered in patients with clinical and imaging suspicion of herpetic encephalitis.

High prevalence of subclinical peripheral artery disease in Greek hospitalized patients.

BACKGROUND: Peripheral artery disease (PAD) represents a common manifestation of systemic atherosclerosis that is associated with an increased risk of cardiovascular death and ischemic events but one that may be underdiagnosed in clinical practice. The purpose of this study was to identify PAD using the ankle-brachial index (ABI) in hospitalized patients from a Department of Internal Medicine and to further investigate the association of this index with traditional cardiovascular risk factors. METHODS: We measured ABI in 990 consecutive patients (400 men and 590 women) aged 50 years or older (71.2+/-9.1) without a history or symptoms suggestive of PAD. ABI values below 0.90 were considered abnormal. RESULTS: PAD was detected in 356 patients (36%), and men had a higher prevalence than women (p<0.001). Hypertension (p<0.001), smoking (p<0.001), diabetes (p<0.05), male sex (p<0.001), and dyslipidemia (p<0.05) were statistically more frequent in patients with PAD, whereas obesity had no significant relation to PAD in our series. In a stepwise, logistic regression analysis, hypertension, male sex, diabetes mellitus, smoking, and dyslipidemia were found to be independent risk factors with odds ratios (95% confidence intervals) of 2.46 (1.85-3.27), 2.25 (1.66-3.05), 1.80 (1.32-2.47), 1.78 (1.31-2.42), and 1.64 (1.22-2.19), respectively. CONCLUSIONS: A simple ABI measurement revealed a large number of patients with unrecognized PAD. It is, therefore, recommended that ABI measurement should be included in the evaluation of cardiovascular risk in hospitalized patients aged 50 years or older.

Coxsackievirus infection associated with acute pancreatitis.

CONTEXT: A variety of infectious agents have been reported as rare causes of acute pancreatitis. CASE REPORT: We briefly describe a 36-year-old man who presented with acute pancreatitis and a maculopapular rash. The marked elevation in antibody titer against coxsackievirus B, as well as the skin biopsy, was compatible with acute coxsackievirus B viral infection. CONCLUSION: This case highlights the fact that an appropriate investigation for viral infections should be performed in patients having acute pancreatitis and no classical risk factors.
