ABSTRACT
The present study aimed to explore the pathogenic spectrum and risk factors of peritoneal dialysis-associated peritonitis (Peritoneal dialysis associated peritonitis, PDAP) in Yongzhou, Hunan, China. The clinical and epidemiological data on regular peritoneal dialysis (Peritoneal dialysis, PD) between January 2016 and December 2020 in Yongzhou were collected for retrospective analysis. The related factors of peritonitis were evaluated by single-factor analysis, while risk factors of refractory PDAP were evaluated by multivariate logistic regression analysis.172/331 172 (51.9%) patients developed peritonitis. The risk factors of PDAP in PD patients included high C-reactive protein (C-reactive protein, CRP), low albumin(Albumin, ALB), low hemoglobin (Hemoglobin, Hb), low educational level (junior high school or lower), preference of spicy food, irregular diet, low annual household income, unfavorable fluid exchange conditions, unstable employment (including working as a farmer), and unfavorable humidity conditions (P < 0.05). 63/172 (36.6%) PDAP patients were intractable cases with a pathogenic bacteria positive rate of 74.60% in the peritoneal dialysate cultures, and 109/172 patients were non-intractable cases with a pathogenic bacteria positive rate of 53.21%. Gram-positive bacteria (G+) were detected in most of the dialysate cultures, with Staphylococcus epidermidis (S. epidermidis) as the most common type, while Escherichia coli (E. coli) was the most common Gram-negative bacteria (G-). Gram-positive bacteria were sensitive to vancomycin and linezolid, while G- bacteria were sensitive to imipenem and amikacin. Lifestyle, educational level, and environmental factors are the major contributors to PDAP in PD patients. Fungal and multi-bacterial infections are the major causes of death; PD is stopped for such patients.

PURPOSE: To explore the effects of combined fenestration of lamina terminalis and Liliequist membrane during surgical clipping on the occurrence of chronic hydrocephalus in patients with ruptured anterior circulation aneurysm. METHODS: Clinical data of 78 patients with anterior circulation ruptured aneurysms who were treated between June 2018 and January 2021 were retrospectively analyzed. Based on the surgical treatment, patients were divided into 3 groups: clipping group (26 cases); fenestration group (lamina terminalis fenestration combined with clipping, 28 cases); and combination group (lamina terminalis fenestration and Liliequist membrane opening combined with clipping, 24 cases). The incidence of postoperative chronic hydrocephalus, the postoperative hydrocephalus shunt rate, and the Glasgow prognostic score (GOS) were evaluated. RESULTS: The incidence of postoperative chronic hydrocephalus in the combined group (16.6 %, 4/24) was significantly lower than that in the clipping group (46.1 %, 12/26) and the fenestration group (35.7 %, 10/28; P < 0.05). The shunt rate of chronic hydrocephalus in the combined group (4.1 %, 1/24) was significantly lower than that in the clipping group (30.7 %, 8/26) and the fenestration group (17.8 %, 5/28; P < 0.05). The rate of postoperative GOS score of 5 in the combined group (75.0 %, 18/24) was significantly higher than that in the clipping group (23.0 %, 6/26) and the fenestration group (57.1 %, 16/28; P < 0.05). CONCLUSION: Aneurysm clipping combined with lamina terminalis fenestration and Liliequist membrane opening can reduce the occurrence of chronic hydrocephalus and the rate of chronic hydrocephalus shunt surgery, thereby improving the prognosis of patients.
