Normal Values of High Resolution Anorectal Manometry in 132 Romanian Healthy People.

BACKGROUND AND AIMS: The primary method for assessing anorectal function is high resolution anorectal manometry (HRAM). It is a useful tool in the diagnosis of different anorectal functional disorders such as fecal incontinence or dyssynergia. The aim of the present study was to propose a new set of normal values to be used in practice for East-European individuals, as it was proven that the results are highly influenced by race and sociocultural status. METHODS: We conducted a study based on anorectal manometric values of healthy volunteers analyzed at Clinic Fundeni Institute, Bucharest, Romania, between 2017 and 2022. The anorectal manometry was performed using a solid-state catheter (Diversatek, 23 pressure sensors). All anorectal measurement values were analyzed using the Bioview Software Analysys, respecting the timing and the order from the standardized IAPWG protocol. Manometric measurements were summarized using mean, median, standard deviation, minimum and maximum values. The impact of age and gender on 8 different manometric parameters was further analyzed. Normal ranges for all numeric variables were estimated using the 5th and 95th percentiles of the measurements. RESULTS: A total of 132 subjects (97 females, 35 males) were enrolled in the study. Median age was similar between groups (54 vs. 55 years). The values for rectal propulsion, anal gradient and anal relaxation proved to be higher in females under 54 years as opposed to older women. The values for resting pressure, maximum squeeze pressure, incremental squeeze pressure were significantly higher in males younger than 54. Regardless of age, values for maximum squeeze pressure, incremental squeeze pressure, duration of squeeze and rectal propulsion were found to be significantly higher in males than in females. Normal values of HRAM in healthy volunteers are presented in a table at the end of the study. CONCLUSIONS: The data presented in the current study are of high value and have a great impact on clinical practice, being the first study offering a spectrum of the normal values for HRAM in an Eastern Europe population.

Diagnostic and prognostic significance of hepatic steatosis in patients with chronic hepatitis C.

Knowing that hepatic steatosis (HS) is a common occurrence in patients with chronic hepatitis C (CHC), it is essential to establish what are the factors that predispose to its occurrence and what is the role of HS in the evolution and prognosis of patients with CHC who develop this feature. To achieve these aims, we performed a retrospective clinical study in 33 patients with CHC hospitalized, diagnosed, and monitored in the 2nd Medical Department of the Emergency County Hospital, Craiova, Romania, in a period of two years (2011-2012). Following clinical, hematological, biochemical, immunological, and pathological investigations of the 33 patients with CHC selected, only 14 patients showed pathological changes of the HS. The appearance of steatosis in patients with CHC results from a complex interaction between the particularities of the host and viral factors. The main risk factors of the host, which contributed to the appearance of HS were sex, age, body mass index (BMI), body weight, and personal history of pathology (obesity, metabolic syndrome). Virus-related factors involved in HS were viremia and viral genotype. In conclusion, HS is a common finding (42.42%) in patients with CHC, particularly genotypes 1 and 2. Early detection of HS by invasive or non-invasive methods is an important objective of monitoring patients with CHC, because HS is correlated with a high degree of fibrosis. Therefore, early correction of metabolic factors and early introduction of antiviral therapy are important targets for treating of patients with CHC.
