Anti-Inflammatory Effects of Campomanesia xanthocarpa Seed Extract Obtained from Supercritical CO2

Campomanesia xanthocarpa is a plant species traditionally used in the treatment of diabetes, fever, hypercholesterolemia, obesity, and urinary tract diseases. The anti-inflammatory effects of C. xanthocarpa leaves in mice were already known. Nevertheless, studies on the anti-inflammatory activity of its seeds are still lacking. The aim of this study was to investigate the anti-inflammatory activity and acute toxicity of C. xanthocarpa seed extract, obtained from supercritical CO₂ extraction (SCCO₂) at 40°C and 250 bar, in mice. GC/MS analysis revealed that β-caryophyllene is the major compound present in the C. xanthocarpa SCCO₂ extract. The extract (60 mg/kg, p.o.) significantly reduced the nociceptive behavior in the second phase of the formalin test and prevented the paw oedema induced by carrageenan up to 6 h after carrageenan injection. The extract (0.1–1 μg/mL) inhibited neutrophils migration induced by LPS from E. coli in vitro. This antichemostatic effect was comparable to the effect of indomethacin. Acute administration (2000 mg/kg, p.o.) of C. xanthocarpa SCCO₂ extract caused no mice mortality, demonstrating that the extract is devoid of acute toxicity. These data suggest that C. xanthocarpa seeds present anti-inflammatory activity and represent a source of anti-inflammatory compounds.

Analysis of long-term results of pathogenetic treatment of Helicobacter pylori-associated gastroduodenopathies induced by nonsteroidal anti-inflammatory drugs in patients with osteoarthritis

The study of the pathogenetic treatment and prevention of Helicobacter pylori (Hp)-associated gastroduodenopathies (GDP) induced by nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with osteoarthritis (OA) is one of the most serious problems in modern clinical medicine. Sixty patients with OA and concomitant Hp-associated GDP induced by NSAIDs were examined. The levels of epidermal growth factor (EDF), sAPO-1/Fas and tumor necrosis factor-α (TNF-α) were determined. Group I included 30 patients who received triple anti-Helicobacter (AHT) therapy, and group II included 30 patients who received rebamipide. Long-term effects were assessed 6 months and 1 year after treatment. All subjects showed a significant increase in TNF-α (4.7 times), EDF (2.2 times) and a decrease in sAPO-1/Fas (3.6 times) levels compared to healthy individuals. After 1 month of treatment, a significantly more significant decrease in TNF-α and an increase in sAPO-1/Fas and EDF was found in group II. In the long-term treatment, a further decrease in TNF-α and an increase in the content of sAPO-1/Fas levels were observed in all groups. However, these changes were significantly more significant in group I compared to group I. The long-term follow-up showed a declining trend of EDF in all groups. The data obtained indicate the effectiveness of rebamipide in the complex pathogenetic treatment and prevention of Hp-associated GDP induced by NSAIDs in patients with OA.

Non-steroidal anti-inflammatory drugs and gastroprotection in primary health care users

Objective

The aim of this study is to assess the prevalence of gastroprotection and identify the main factors that influence the taking of protective drugs by the adult population treated with non-steroidal anti-inflammatory drugs (NSAID).

Methods

This study was cross-sectional, conducted by including a contingent of 800 users of primary health care services (n=369, 46% males and n=431, 54% females). Included in the study were individuals of both genders aged 18+ who sought counselling or treatment during the three-month period. The data collection of this study was based on the completion of a structured questionnaire, which included questions related to the use of NSAIDs, the way these drugs were prescribed and administered and the simultaneous taking of gastroprotective drugs.

Results

The prevalence of the gastroprotective drugs use was higher among the elderly, individuals living in urban areas, those with higher education, those with daily use of NSAID, individuals receiving prescriptions from their own doctors, and those suffering from side effects from the use of NSAID, as well as subjects that had a longer duration of NSAID use. Diclofenac was the most prescribed NSAID. Gastric pain and dizziness were the most experienced side effects.

Conclusion

This paper demonstrates the need to improve the quality of primary health care service through informing and educating patients regarding the need to take gastro-protective drugs for those at high risk of adverse effects manifested by the use of NSAIDs.
