Evidence that oral immunoglobulins (KMP01) suppress pro-tumor inflammation in rectal carcinoma: Case report and treatment concept.

BACKGROUND: A female patient aged 49 years with a rectal adenocarcinoma underwent tumor resection and multiple follow-up surgical operations whilst receiving compassionate therapy with polyvalent immunoglobulins derived from bovine colostrum (KMP01), a potential modulator of the pro-tumor inflammatory response. AIMS: Assessment of safety of the treatment, effect on tumor recurrence, and effect on parameters associated with the pro-tumor inflammatory response. MATERIALS AND METHODS: The dose of KMP01 varied from 72 g daily in the perioperative period to 12 - 24 g daily thereafter. The pro-tumor inflammatory response was measured using changes in C-reactive protein (CRP) and the lymphocyte-monocyte ratio (LMR). RESULTS: Surgical intervention caused large increases in CRP (up to 400 mg/L) and decreases in the LMR (below target levels of 2.83). However, such changes rapidly returned to normal, where they remained during prolonged treatment with immunoglobulins. Despite the generally poor prognosis associated with a stenotic tumor, cachexia, and multiple surgery, there was no tumor recurrence during the 3-year follow-up. The condition of the patient is good, albeit with a reduced quality of life due to the stoma. CONCLUSION: Polyvalent immunoglobulins constitute a potential and safe prophylactic agent against the pro-tumor inflammatory response. This is the first time that polyvalent immunoglobulins have been used in a colorectal carcinoma patient. The findings can be a basis for further investigations.

Effect of 2D vs. 3D laparoscopy on postoperative complications and operation time in a propensity-score-matched real-world data analysis.

BACKGROUND: Postoperative complication rates using 3D visualization are rarely reported. The primary aim of our study is to detect a possible advantage of using 3D on postoperative complication rates in a real-world setting. METHOD: With a sample size calculation for a medium effect size difference that 3D reduces significantly postoperative complications, data of 287 patients with 3D visualization and 832 with 2D procedure were screened. The groups underwent an exact propensity score-matching to be comparable. Comprehensive complication index (CCI) for every procedure was calculated and Operation Time was determined. RESULTS: Including 1078 patients in the study, 213 exact propensity score-matched pairs could finally be established. Concerning overall CCI (3D: 5.70 ± 13.63 vs. 2D: 3.37 ± 9.89; p = 0.076) and operation time (3D: 103.98 ± 93.26 min vs. 2D: 88.60 ±6 9.32 min; p = 0.2569) there was no significant difference between the groups. CONCLUSION: Our study shows no advantage of 3D over 2D laparoscopy regarding postoperative complications in a real-world setting, the second endpoint operation time, too, was not influenced by 3D overall.

Pseudomonas aeruginosa population genomics among adults with bronchiectasis across Germany.

Genome sequencing of 130 Pseudomonas aeruginosa isolates from 110 bronchiectasis patients identified a few dominant clones common in the global bacterial population and numerous rare clones infrequently seen in the environment or other human infections https://bit.ly/3lIfD2X.
