epiglucan and Multiple-Organ-Failure

We showed previously that probiotics containing lactobacilli significantly improve the outcome of acute pancreatitis. "Synbiotic 2000", a new synbiotic composition with high colony forming unit (CFU) comprises four different types of pre- and probiotics. In this prospective, randomized, double-blind study we evaluated the role of "Synbiotic 2000" in the treatment of severe acute pancreatitis.. Patients with severe acute pancreatitis were randomized into two groups. Nasojejunal feeding was commenced within 24 hours after admission in both groups and continued for at least seven days. The first group of patients received four different lactobacilli preparations with 10(10) CFU, respectively, and prebiotics containing four bioactive fibres (inulin, beta-glucan, resistant starch and pectin) in addition. Patients in the second (control) group received only prebiotics.. 62 patients with severe acute pancreatitis completed the study. Altogether 8 patients died. We detected lower incidence of multiorgan failure (MOF), septic complications and mortality in the first group compared to the control, but the differences were statistically not significant. The total incidence of systemic inflammatory response syndrome (SIRS) and MOF were significantly different between the two groups (8 vs. 14; p < 0.05). Furthermore, the number patients recovering with complications were significantly less in the first group receiving modern synbiotic therapy compared to the control (p < 0.05). Finally, we found lower rate of late (over 48 hours) organ failure in the first versus the control group (3.0% vs. 17.2%).. Our results suggest that early nasojejunal feeding with synbiotic may prevent organ dysfunctions in the late phase of severe acute pancreatitis. In addition, our data also indicate that the infection of pancreatic necrosis may be associated with early phase organ failure.

Disseminated Scedosporium prolificans infection occurs mainly in immunocompromised patients. The mortality rate is high, as the fungus is resistant to most antifungal agents. Here, we present the case of a 66-year-old female with acute myeloid leukemia who developed infective endocarditis caused by S. prolificans infection during induction chemotherapy. Her 1,3-β-D-glucan levels were elevated and computed tomography revealed bilateral sinusitis and disseminated small nodular masses within the lungs and spleen; it nonetheless took 6 days to identify S. prolificans by blood culture. The patient died of multi-organ failure despite the combined use of voriconazole and terbinafine. Autopsy revealed numerous mycotic emboli within multiple organs (caused by mitral valve vegetation) and endocarditis (caused by S. prolificans). The geographic distribution of this infection is limited to Australia, the United States, and southern Europe, particularly Spain. The first Japanese case was reported in 2011, and four cases have been reported to date, including this one. Recently, the incidence of S. prolificans-disseminated infection in immunocompromised patients has increased in Japan. Therefore, clinicians should consider S. prolificans infection as a differential diagnosis when immunocompromised patients suffer disseminated infections with elevated 1,3-β-D-glucan levels.

Scedosporium prolificans (S. prolificans) is a type of mold, which rarely affects immunocompromised people. We treated a 71-year-old woman with acute myeloid leukemia (AML-M5a) with low-dose cytarabine, acralubicin, and filgrastim as the induction therapy. On day 7 after the initiation of chemotherapy, she became febrile and agranulocytic, and developed anal pain ; therefore, we discontinued the chemotherapy on day 8. Broad-spectrum antibiotics, micafungin, and then liposomal amphotericin B were ineffective. The serum concentration of β-D-glucan was 525 pg/mL. She died of multiple organ failure on day 17. S. prolificans was detected from the blood culture on day 13. Physicians should consider Scedosporium spp. infection when principal antifungal agents are ineffective and fungal infection is strongly suspected.

beta-Glucans are glucose polymers with a variety of stimulatory effects on the immune system. The objective of this study was to determine the effect of prophylactic oral administration of soluble Saccharomyces cerevisiae-derived beta-1,3/1,6-glucan (SBG) on the outcome of experimental endotoxaemia and shock-associated organ injury. Male Wistar rats were pretreated with SBG orally (SBGpo, 20 mg/kg/day) for 14 days, subcutaneously (SBGsc, 2 mg/kg/day) for 3 days, or vehicle (placebo). Rats were anaesthetized and subjected to endotoxaemia by intravenous infusion of Escherichia coli lipopolysaccharide (LPS) (6 mg/kg) or saline infusion (sham). We observed significant levels of plasma beta-glucan in the SBGpo group (P<0 x 5), although the SBGsc group had levels approximately 40-fold higher despite a 10-fold lower dose. SBG prophylaxis caused enhanced blood pressure recovery following LPS-induced blood pressure collapse. Oral treatment with SBG attenuated the LPS-induced rise in plasma creatinine levels (P<0 x 05), indicating protection against renal injury. SBG also attenuated the plasma levels of aspartate aminotransferase and alanine aminotransferase (SBGpo, P<0 x 01; SBGsc, P<0 x 01), indicating protection against LPS-induced hepatic injury. A moderate increase in baseline interleukin (IL)-1beta levels was observed in the SBGsc group (P< 0 x 05). In the LPS-challenged rats, plasma levels of proinflammatory cytokines was moderately reduced in both SBG-treated groups compared to placebo. SBG treatment, particularly oral administration, had a striking effect on the haemodynamics of LPS-treated rats, although only a minute fraction of the orally administered beta-glucan translocated to the circulation. Enhanced organ perfusion may thus be responsible for the attenuated levels of indicators of kidney and liver injury seen in SBG-treated rats.

Circulatory failure in multiple organ dysfunction syndromes (MODS) is characterized with systemic vasodilation, diminished blood flow to various vascular beds. The aim of this study was to investigate the effects of selective inhibition of nitric oxide on the mesenteric arterial blood flow (MABF), survival and organ injury of the liver, kidney, lung and spleen in zymosan-induced MODS.. Forty Swiss albino mice (20-40 g), 7 to 9 weeks old, were obtained. Animals were randomly divided into four groups. The first group were treated intraperitoneally (i.p) with vehicle (saline) and served as a sham group for aminoguanidine (AG) (n=10). The second group was treated with zymosan (500 mg/kg, suspended in saline solution, i.p). The mice in the third and fourth group received AG (15 mg/kg) 1 h and 6 h after zymosan or saline administration, respectively. Eighteen hours after the administration of zymosan, animals were assessed for MODS described subsequently. The signals from the flowmeter were also recorded on mesenteric arterial blood flow values.. In zymosan-treated animals, the MABF was significantly lower than that of solvent (saline)-treated controls (ml min(-1), controls: 4.6 +/- 0.6; zymosan: 1.6 +/- 0.9, P <0.05). When animals were treated with AG, there were no significant differences in MABF values between AG group and solvent (saline)-treated control group. However AG prevented zymosan-induced mesenteric MABF decrease. Treatment with aminoguanidine also decreased mortality.. AG is capable of inhibiting both the induction and the activity of the already iNOS; it remains a potential therapeutic agent in patients with MODS.
