Pantethine and fursultiamine have been evaluated for their clinical usefulness in the treatment and prevention of uncomplicated postoperative adhesive intestinal obstruction. In recent years, the actions of drugs used to treat gastrointestinal diseases have been elucidated pharmacologically from the viewpoints of gastrointestinal peptide levels. We examined the effects of pantethine and fursultiamine on plasma levels of calcitonin gene-related peptide (CGRP)-, vasoactive intestinal polypeptide (VIP)-, motilin- and substance P (SP)-like immunoreactive substances (IS) in healthy subjects. An open-labeled study was conducted on five healthy volunteers. Each subject was administered a single oral dose of pantethine, fursultiamine and placebo at intervals of one month. Venous blood samples were collected before and at 20, 40, 60, 90, 120, 180 and 240 min after each administration. Plasma peptide levels were measured using a highly sensitive enzyme immunoassay. A single oral dose of pantethine resulted in significant increases of plasma CGRP- and VIP-IS levels compared to placebo. Furthermore, areas under the plasma concentration-time curves (AUC(0-240)) of CGRP- and VIP-IS were significantly higher after pantethine administration compared with placebo. On the other hand, fursultiamine had no effect on plasma levels and AUC(0-240) of CGRP-, VIP-, motilin- and SP-IS. This study demonstrated the different effects of pantethine and fursultiamine from the viewpoint of plasma gastrointestinal peptide changes. The pharmacological effects of pantethine may be closely related to the changes in plasma CGRP- and VIP-IS levels.

Despite advances in treatment and prevention, peritonitis remains a major problem in peritoneal dialysis (PD) patients with often technique failure as a consequence. The last decades the focus of PD peritonitis has changed from lowering peritonitis incidence to improvement of peritonitis outcome. Prognostic factors for peritonitis outcome can influence decision making during the treatment of peritonitis, for example to take out the PD catheter early in the time course of peritonitis and prevent further damage to the peritoneal membrane. In this paper, we give a review of the literature about prognostic factors for peritonitis outcome. In most studies, age, gender, diabetes, time on PD, a precursor of calcitonin:procalcitonin, IL-6 and albumin did not show a significant effect on peritonitis outcome. The following factors have been associated with poor outcome of peritonitis: Gram-negative organisms, Mycobacterium species, fungal peritonitis, polymicrobial peritonitis, concurrent exit site or tunnel infection, Caucasian race, low residual GFR, persistently elevated peritoneal dialysate white cell count, CRP, and low levels of slCAM-1 and hyaluronan at the end of peritonitis treatment. In fungal peritonitis, abdominal pain, bowel obstruction, the catheter remaining in situ and Candidaparapsilosis are factors associated with higher mortality rate and a greater risk of technique failure. Recent antibiotic therapy and peritonitis are associated with poor treatment response in culture-negative peritonitis. Recurrent peritonitis episodes have a poor therapeutic response and high mortality and have a worse prognosis than relapsing ones. Older age, long PD duration and continuous elevated serum CRP levels are predictors of adverse outcomes in PD patients after peritonitis-related catheter removal. Peritonitis remains a serious complication of PD with marked morbidity. It is a common cause of technique failure. The rate of PD-related peritonitis has decreased over the last decades due to advances in treatment and prevention. Nowadays, the focus moved from lowering peritonitis incidence towards improving peritonitis outcome. It is useful to have prognostic factors for peritonitis outcome, because they can influence decision-making during the treatment of peritonitis, for example to take out the PD catheter early in the time course of peritonitis and prevent further damage to the peritoneal membrane. In the last decades, many publications appeared about prognostic factors for peritonitis outcome. This article summarizes those prognostic factors, based on an extensive review of the literature.
