ABSTRACT

Incontinence-associated dermatitis (IAD) is a painful complication in elderly patients, leading to reduced quality of life. Despite recent attention, its underlying inflammatory mechanisms remain poorly understood. This study was designed to quantify the release of inflammatory cytokines in a human model of IAD. The left volar forearm of ten healthy volunteers was exposed to synthetic urine and synthetic faeces for 2 h, simulating the effects of urinary and faecal incontinence, respectively, and the subsequent cytokine response compared to that of an untreated control site. Inflammatory cytokines were collected using both the Sebutape® absorption method and dermal microdialysis and quantified using immunoassays. Results from the former demonstrated an upregulation in IL-1α, IL-1RA and TNF-α. Synthetic urine caused a higher median increase in IL-1α from baseline compared to synthetic faeces, whereas synthetic faeces were associated with significantly higher median TNF-α levels compared to synthetic urine (p = 0.01). An increase in IL-1α/IL-1RA ratio was also observed with significant differences evident following exposure to synthetic urine (p = 0.047). Additionally, microdialysis revealed a time-dependent increase in IL-1ß and IL-8 following exposure of up to 120 min to synthetic urine and synthetic faeces, respectively. This study demonstrated the suitability of both sampling approaches to recover quantifiable cytokine levels in biofluids for the assessment of skin status following exposure to synthetic fluids associated with incontinence. Findings suggest some differences in the inflammatory mechanisms of IAD, depending on moisture source, and the potential of the cytokines, IL-1α and TNF-α, as responsive markers of early skin damage caused by incontinence.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: Vitamin D is an important micronutrient in muscle function. We hypothesize that vitamin D deficiency may contribute to fecal incontinence (FI) symptoms by affecting the anal continence mechanism. Our goal was to characterize the association of vitamin D deficiency as a variable affecting FI symptoms and its impact on health-related quality of life (HR-QoL). METHODS: This case-control study assessed women seen at a tertiary-care referral center. Participants were identified as having had a serum vitamin D level obtained within a year of their visit: cases were women presenting for care for FI symptoms; controls were women without any pelvic floor symptoms presenting to the same clinical site for general gynecologic care. Cases completed the Modified Manchester Health Questionnaire (MMHQ) and the Fecal Incontinence Severity Index to measure symptom severity and burden on QoL. RESULTS: Among the 31 cases and 81 controls, no demographic or medical differences existed. Women with FI had lower vitamin D levels (mean 29.2 ± 12.3 cases vs. 35 ± 14.1 ng/ml controls p = 0.04). The odds of vitamin D deficiency were higher in women with FI compared with controls [odds ratio (OR) 2.77, 95 % confidence interval (CI) 1.08-7.09]. Among cases, women with vitamin D deficiency (35 %) had higher MMHQ scores, indicating greater FI symptom burden [51.3 ± 29.3 (vitamin D deficient) vs. 30 ± 19.5 (vitamin D sufficiency), p = 0.02]. No differences were noted for FI severity, p = 0.07. CONCLUSIONS: Vitamin D deficiency is prevalent in women with fecal incontinence and may contribute to patient symptom burden.

ABSTRACT

AIM: To evaluate the outcome of transrectal irrigation (TRI) using clean tap water without salt in children with myelomeningocele and neurogenic bowel problems. METHODS: 40 children (21 boys and 19 girls; aged 10 mo to 11 y) with myelomeningocele and neurogenic bowel dysfunction were treated with TRI given by a stoma cone irrigation set daily or every second day. A questionnaire on the effects on faecal incontinence, constipation and self-management was completed by the parents, 4 mo-8 y (median 1.5 y) after start. Effects on rectal volume, anal sphincter pressure and plasma sodium were evaluated before and after the start of irrigation. RESULTS: At follow-up, 35 children remained on TRI, four had received appendicostomy, while one defecated normally. For all children but five (35/40; 85%) the procedure worked satisfactorily, but a majority found the procedure very time consuming and only one child was able to perform it independently. All children were free of constipation; most (35/40) were also anal continent. Rectal volume and anal sphincter pressure improved, while plasma sodium values remained within the normal range. CONCLUSION: Transrectal irrigation with tap water is a safe method to resolve constipation and faecal incontinence in children with myelomeningocele and neurogenic bowel dysfunction, but it does not help children to independence at the toilet.
