Background: The incidence of high-output stoma (HOS) was reported to be approximately 3 to 16% in the literature, and HOS can cause dehydration. This complication is often severe enough to warrant hospital readmission and may result in renal failure. The aim of this study was to show a decrease of 50% in ileostomy output in the experimental arm using lanreotide treatment., Methods: Patients with an ileostomy output ≥ 1.5 l/24 hours were included in this prospective, open, multicentre randomized trial. Patients were randomly allocated between treatment arms with either lanreotide (LAN) and antidiarrhoeal treatments (TAD) (LAN-TAD group) or antidiarrhoeal treatments only (TADS group). The primary outcome was ileostomy output after 72 days. The secondary endpoints were ileostomy output during the first 6 days, blood urea and creatinine values, hospital length of stay and serious adverse events., Results: In the per-protocol analysis, there were nine patients in the control group (TADS) and six patients in the experimental group (TAD-LAN group). The stoma outputs at Day 3 (D3) in the experimental and control groups were 1,900 ± 855.7 mL and 1,728.6 ± 845.5 mL, respectively ( p  = 0.2). No differences were found concerning stoma output at D6, renal function, or hospital length of stay between the two groups., Conclusion: The trial was prematurely stopped due to the low number of patients included. The question of the usefulness of somatostatin analogues in HOS persists, especially as the cost of this treatment is high, and there is a lack of evidence of its effectiveness.

Approximately one-third of the human population is asymptomatically colonized by Staphylococcus aureus. However, much of the global diversity within the carriage populations remains uncharacterized, and it is unclear to what degree the variation is geographically partitioned. We isolated 300 carriage isolates from 1,531 adults contemporaneously in four countries: France, Algeria, Moldova, and Cambodia. All strains were characterized by multilocus sequence typing. Six clonal complexes (CCs) were present in all four samples (CC30, -45, -121, -15, -5, and -8). Analyses based on the genotype frequencies revealed the French and Algerian samples to be most similar and the Cambodian sample to be most distinct. While this pattern is consistent with likely rates of human migration and geographic distance, stochastic clonal expansion also contributes to regional differences. Phylogenetic analysis revealed a highly divergent and uncharacterized genotype (ST1223) within Cambodia. This lineage is related to CC75, which has previously been observed only in remote aboriginal populations in northern Australia.

In staphylococci, methicillin (meticillin) resistance (MR) is mediated by the acquisition of the mecA gene, which is carried on the size and composition variable staphylococcal cassette chromosome mec (SCCmec). MR has been extensively studied in Staphylococcus aureus, but little is known about MR coagulase-negative staphylococci (MR-CoNS). Here, we describe the diversity of SCCmec structures in MR-CoNS from outpatients living in countries with contrasting environments: Algeria, Mali, Moldova, and Cambodia. Their MR-CoNS nasal carriage rates were 29, 17, 11, and 31%, respectively. Ninety-six MR-CoNS strains, comprising 75 (78%) Staphylococcus epidermidis strains, 19 (20%) Staphylococcus haemolyticus strains, 1 (1%) Staphylococcus hominis strain, and 1 (1%) Staphylococcus cohnii strain, were analyzed. Eighteen different SCCmec types were observed, with 28 identified as type IV (29%), 25 as type V (26%), and 1 as type III (1%). Fifteen strains (44%) were untypeable for their SCCmec. Thirty-four percent of MR-CoNS strains contained multiple ccr copies. Type IV and V SCCmec were preferentially associated with S. epidermidis and S. haemolyticus, respectively. MR-CoNS constitute a widespread and highly diversified MR reservoir in the community.
