RESUMO

PURPOSE: The superior orbital fissure contains cranial nerves III, IV, VI, and V1 with their three branches: frontal, lacrimal, and nasociliary. Superior orbital fissure syndrome (SOFS) is rare and can occur as a result of compression of these nerves due to trauma, bleeding, or inflammation in the retrobulbar space, but no cases of SOFS after deep lateral orbital wall decompression (DLOWD) have been reported. The aim of this paper is to describe this pathology, its possible causes, management, and outcome. METHODS: Retrospective study of 575 DLOWD in patients with disfiguring exophthalmos due to Graves' ophthalmopathy performed in our hospital between 2010 and 2023. Three cases of postoperative SOFS were identified based on clinical presentation, history, physical examination, and radiological study. All patients were observed for a minimum of 12 months. RESULTS: SOFS was diagnosed with the presence of ophthalmoplegia, ptosis, fixed and dilated pupils, hypo/anesthesia of the upper eyelid and forehead, loss of corneal reflex, and no loss of vision after DLOWD. Fractures, edema, and hemorrhages were excluded. They were treated with high-dose intravenous steroids and the patients recovered completely. CONCLUSIONS: DLOWD challenges orbital surgeons because it requires removing bones near the globe or neurovascular structures. SOFS may occur due to the proximity and increased pressure on these structures.

RESUMO

AIMS: Antiretroviral (ARV) therapy reduces inflammation and immune activation in people with HIV, but not down to the levels observed in people without HIV. Limited drug penetration within tissues has been argued as a potential mechanism of persistent inflammation. Data on the inflammation role on ARV plasma/intracellular (IC) pharmacokinetics (PK) through to expression of cytochrome P450 3A/membrane transporters are limited. The aim of this study was to investigate the correlation between inflammation markers (IM) and plasma/IC PK of ARV regimen in HIV-positive patients. METHODS: We included ART-experienced patients switching to three different ARV regimens. Plasma and IC ARV drug concentration means at the end of dosing interval (T0 ), IM on samples concomitantly with ARV PK determination: sCD14, CRP, IL-6 and LPS were analysed. RESULTS: Plasma and IC drug concentrations were measured in 60 samples. No significative differences between CRP, sCD14, IL-6 and LPS values in the three arms were observed. A significant inverse correlation between tenofovir plasma concentration and sCD14 (rho = -0.79, P < .001), and between DRV IC/plasma ratio and Log10 IL-6 concentrations (rho = -0.36, P = .040), and a borderline statistically significant positive trend between DRV plasma concentration and sCD14 (rho = 0.31, P = .070) were suggested. Furthermore, a borderline statistically significant inverse trend between DTG IC concentrations and sCD14 (rho = -0.34, P = .090) was observed in 24 patients on DTG-based triple therapy. CONCLUSIONS: Our preliminary data support the hypothesis of lower DRV and DTG IC concentrations and lower TFV plasma exposure in patients with higher plasma IM suggesting an interplay between HIV drug penetration and persistent inflammation in cART-treated HIV-positive patients.

RESUMO

PURPOSE: Orbital tumor surgery can be challenging when the tumor is located in a very narrow surgical field and close to important structures, such as nerves or extraocular muscles that can be damaged during surgery. Advances in technology and special surgical techniques help to avoid such damage. We describe our experience using SONOPET® ultrasonic surgical aspirator to remove 12 different orbital tumors that were difficult to treat due to their poorly defined borders, adhesions, or location. METHODS: This is a retrospective case series that describes 12 operations that occurred between March 2016 to December 2018 using an ultrasonic device to debulk or remove orbital tumors. Different approaches and handpieces were used for each case depending on the location and consistency of the tumor. RESULTS: All patients experienced an improvement in preoperative signs and symptoms, pain, proptosis, diplopia, or lagophthalmos. Visual acuity, which had been reduced due to the tumor, was also recovered. There were no intraoperative or postoperative complications due to the use of the device. CONCLUSIONS: The ultrasonic aspirator is a safe, useful device that can successfully remove or debulk infiltrating orbital masses through any orbital access, regardless of their consistency. It is helpful in cases of difficult anatomical access or difficult extraction due to size or adhesions to the surrounding tissues.

RESUMO

BACKGROUND: When Rectocele is part of a complex pelvic organ prolapse, a full repair is recommended. The aim of this study was to evaluate the clinical and radiological results after laparoscopic surgery in patients with symptomatic rectocele and III/IV stage vaginal vault prolapse METHODS: This is a prospective cohort study of women with symptomatic rectoceles and middle compartment prolapse operated on between 2013 and 2015, who underwent a laparoscopic sacrocolpoperineopexy with synthetic Y mesh attached to puborectalis muscles, the anterior and posterior vagina wall and the sacrum. The clinical outcomes measured were symptoms of prolapse, obstructive defecation syndrome and quality of life. Radiological outcomes were distance of the vaginal vault below pubococcigeal line and depth of rectovaginal wall protrusion in dynamic pelvic resonance. RESULTS: 33 patients were included. 32 of them remained asymptomatic after a three years follow-up. Significant differences were shown in the obstructed defecation score and quality of life after 6, 12 and 36 months compared to preoperatively. No differences were identified when the postoperative results were compared. Significant differences were shown in preoperative vaginal vault prolapse (3.2 cms ± 0.8 SD below the pubococcigeal Line) and rectocele size, compared with 1 and 3 years after surgery. There were no significant differences in vaginal vault prolapse when compared after 1 and 3 years. When rectocele size after 1 and 3 years was compared, significant differences were shown, but only one clinical recurrence (3%) was identified after a mean follow-up of 47 months. CONCLUSIONS: Laparoscopic sacrocolpoperineopexy in patients with symptomatic rectocele and III/IV vaginal vault prolapse solves the constipation and obstructed defecation with an excellent quality of life and low clinical recurrences. Radiological deterioration, especially in rectocele size, was identified in the mid-term follow-up without clinical significance.

RESUMO

OBJECTIVE: To review mortality rates in benign gynecologic minimally invasive laparoscopic and robotic surgery (MIS) and the rates associated with commonly performed MIS procedures. DATA SOURCES: An electronic-based search was performed on PubMed, Embase, Scopus, Web of Science, and Cochrane Database for articles published in the last 10 years in English, French, German, Spanish, and Italian. METHODS OF STUDY SELECTION: All MIS articles in benign gynecology reporting operative mortality (within 30 days) were reviewed. TABULATION, INTEGRATION, AND RESULTS: The articles identified through the aforementioned search criteria were independently evaluated by the first 2 authors. The Newcastle-Ottawa scale for observational studies and Cochrane risk-of-bias assessment tool for randomized controlled trials were used to assess the risk of bias. Meta-analysis was applied to calculate pooled mortality rates using the inverse-variance method. Twenty-one articles (124 216 patients) were included. Operative mortality from any benign MIS (laparoscopy and robotics) procedure was 1:6456 (95% confidence interval [CI]: 1:3946-1:10 562). Studies were then grouped based on the surgical procedure. The mortality rate for hysterectomy (119 721 patients), sacrocolpopexy, and adnexal surgery and diagnostic laparoscopy was 1:6814 (95% CI: 1:4119-1:11 275), 1:1246 (95% CI: 1:36-1:44 700), and 1:2245 (95% CI: 1:45-1:113 372), respectively. Eighteen articles reported operative mortality for laparoscopic surgery and 4 for robotic surgery. CONCLUSION: Operative mortality in benign minimally invasive gynecologic surgery is low, and mortality for laparoscopic and robotic approaches appears to be similar.

RESUMO

STUDY OBJECTIVE: To describe a robotic approach to excision of full-thickness diaphragmatic endometriosis. DESIGN: Surgical technique demonstration. SETTING: Symptomatic diaphragmatic endometriosis is commonly associated with lesions that are deeply invasive. In the presence of symptomatic diaphragmatic endometriosis, the posterior diaphragm should be explored. INTERVENTIONS: This video presents a systematic robotic approach to the excision of diaphragmatic endometriosis, highlighting key anatomic landmarks and technical considerations to complete the procedure safely and effectively. Resection of hepatic ligaments, use of a 30° endoscope, and right lateral access can be used to visualize this anatomic area [1]. The phrenic nerve is rarely identified during laparoscopy, if at all, and an inability to identify this structure during hemidiaphragm resection does not seem to result in significant patient morbidity. After diaphragm resection, the pleural cavity and lung should be systematically inspected to rule out the presence of additional endometriotic lesions. If the long axis of the diaphragmatic defect is parallel to the posterior chest wall and can be closed tension-free, then mesh is not necessary [1]. Insertion of a red rubber catheter into the thorax along with the use of negative pressure suction at the end of closure of the diaphragmatic defect may avoid use of a postoperative chest tube. CONCLUSION: The use of robotic assistance for resection of diaphragmatic endometriosis makes this procedure easy and safe to perform. Compared with ablative procedures, complete surgical excision offers higher rates of symptom improvement and resolution in patients with diaphragmatic endometriosis.

RESUMO

STUDY OBJECTIVE: To identify risk factors associated with postoperative urinary retention in patients undergoing outpatient minimally invasive hysterectomy. DESIGN: A retrospective cohort study. SETTING: An academic medical center. PATIENTS: All patients undergoing outpatient minimally invasive hysterectomy between January 2013 and July 2018 were considered for inclusion in the study. INTERVENTIONS: Outpatient laparoscopic, vaginal, or robotically assisted laparoscopic hysterectomy. MEASUREMENTS AND MAIN RESULTS: Four hundred forty-four patients met the inclusion criteria. Postoperative urinary retention occurred in 94 patients, and 347 patients successfully passed their voiding trial in the postanesthesia care unit for a pass rate of 79%. Demographic characteristics were similar, except patients who experienced postoperative urinary retention were less likely to be menopausal (23.4% vs 34.7%, p = .038). Those with urinary retention received more perioperative opioids (morphine milligram equivalent of 14.4 mg vs11.2 mg, p = .012), had longer operative times (122.9 ± 55.6 vs 95.7 ± 42.3 minutes, p < .01), and experienced more blood loss (105.3 ± 134.4 vs 78.5 ± 86.8 mL, p = .025). The rate of urinary tract infections was similar. Logistic regression analysis showed that the route of hysterectomy and age were not associated with an increased risk for urinary retention, whereas a longer operative time and higher doses of perioperative opioid use were. CONCLUSION: In patients undergoing minimally invasive outpatient hysterectomy, a longer operative time and increased perioperative narcotic use increases the risk of postoperative urinary retention.

RESUMO

Purpose: To share our experience on deep lateral wall rim-sparing orbital decompression for the prevention of further spontaneous globe subluxation, in patients with shallow orbits and eyelid laxity.Methods: This is a retrospective, interventional case series review. We report the results of deep lateral wall rim-sparing orbital decompression in 7 patients with recurrent spontaneous globe subluxation, operated in our department between 2010 and 2016. The orbital morphology was established by computed tomography scan images, and all patients with shallow orbit configuration and who in addition had eyelid laxity were included. Patients with thyroid eye disease were excluded.Results: No significant intraoperative and postoperative complications were encountered. In all cases, the patients were satisfied with the aesthetic result and none reported further episodes of globe subluxation.Conclusions: Deep lateral wall rim-sparing orbital decompression is a safe and effective decompressive procedure associated with minimal complications, which can be performed successfully in patients with spontaneous globe subluxation associated with shallow orbits with enough eyelid laxity.

RESUMO

STUDY OBJECTIVE: To describe a standardized technique for robotic complete excision of sacrocolpopexy mesh. DESIGN: A step by step video demonstration of the technique. SETTING: A tertiary care academic hospital. PATIENTS: Three patients with persistent pain after sacrocolpopexy mesh insertion. Although exposure can usually be controlled with partial mesh removal, complete excision may be required for patients with persistent pain, exposure, or severe infection. Because of the inherent inflammation, fibrosis, and distortion of tissue planes with mesh augmentation, removal should be performed in a methodical fashion, preparing for possible visceral injury. INTERVENTION: Robotic-assisted sacrocolpopexy mesh removal. MEASUREMENTS AND MAIN RESULTS: This video (Video 1) presents a systematic, minimally invasive approach to sacrocolpopexy mesh removal, highlighting the technical and anatomic aspects that can facilitate the procedure. Retroperitoneal dissection along with identification of the anatomic landmarks, such as the sacral promontory, iliac vessels, right ureter, bladder, and rectum, are critical. Backfilling the bladder and the use of vaginal and rectal probes can also optimize difficult tissue planes. In each compartment, identifying the whole mesh before starting its removal may prevent leaving mesh fragments. The caudal to cranial and lateral to medial approach facilitates the extraction of the synthetic tissue. Removing the sacral mesh last allows the attachment to be used as a point of traction. Superior dissection of the mesh requires careful dissection and recognition of great vessels along with autonomic nervous structures such as the superior hypogastric plexus. CONCLUSION: Minimally invasive removal of sacrocolpopexy mesh can be standardized using this step by step approach.

RESUMO

OBJECTIVE: To review early operative mortality (<30 days) for minimally invasive surgery (MIS), laparoscopic and robotic, in gynecologic oncology. DATA SOURCES: An electronic-based search was performed in PubMed, Embase, Scopus, Web of Science, and Cochrane Database in the last 10 years. METHODS OF STUDY SELECTION: All MIS studies in gynecologic oncology reporting operative mortality from any cause (within 30 days) were included. Studies were excluded if mortality was not reported for MIS or included benign gynecology. TABULATION, INTEGRATION, AND RESULTS: Meta-analysis was applied to calculate pooled mortality rates using the inverse-variance method. The relative risks and their corresponding 95% confidence intervals (CIs) were calculated using the Mantel-Haenszel method. Sixty-five studies were included (39 183 patients) for an operative mortality of 1:381 (95% CI, 1:306-1:474). Studies were subselected and analyzed by procedures, malignancy, and surgical approach. Of 39 183 patients, 38 619 underwent any type of hysterectomy for a mortality of 1:379 (95% CI, 1:304-1:472). The mortality was 1:281 (95% CI, 1:169-1:469) for a laparoscopic approach and 1:476 (95% CI, 1:365-1:620) for a robotic approach. There were 3369 patients with early cervical cancer undergoing radical hysterectomy with a mortality of 1:2049 (95% CI, 1:356-1:11 832). There were 3501 patients with endometrial cancer undergoing hysterectomy with lymph node dissection with a mortality of 1:195 (95% CI, 1:109-1:349). There were 418 patients with ovarian cancer undergoing MIS procedures with a mortality of 1 in 685 (95% CI, 1:44-1:10971). Eleven studies with 4037 patients compared mortality of gynecologic oncology surgery of any type (laparoscopic [1:626] vs robotic [1:716] for a relative risk of 1.12 [95% CI, 0.35-3.49]). CONCLUSION: The overall operative mortality for minimally invasive surgery in gynecologic oncology is 1 in 381 (95% CI, 1:306-1:474). For patients with early cervical cancer, it is 1:2049 (95% CI, 1:356-1: 11832), for endometrial cancer with node dissection it is 1:195 (95% CI, 1:109-1:349), and for ovarian cancer it is 1 in 685 (95% CI, 1:44-1:10 971). There is no difference between the type of MIS approach for patients undergoing any type of gynecologic oncology surgery.

RESUMO

OBJECTIVE: To demonstrate our experience with hysteroscopic assistance in the laparoscopic repair of an isthmocele. DESIGN: Surgical video article (Canadian Task Force classification III). SETTING: University hospital. INTERVENTION: A 42-year-old woman with a history of previous caesarean section presented as an emergency with a large, seriously infected isthmocele. Once the infection was cured with antibiotics, sonography revealed a 23 × 14-mm isthmocele with 1.4-mm residual myometrium thickness. She reported postmenstrual spotting and dysmenorrhea of several years duration, as well as previous dyspareunia that had worsened after her cesarean section. Given her symptomatic isthmocele with thin residual myometrium and desire for childbearing, laparoscopic repair was offered. First, the bladder was dissected to expose the isthmus. Uterine arteries were dissected. Hysteroscopic guidance and transillumination revealed the edges of the defect. The isthmocele and fibrotic tissue were excised with cold scissors, minimizing cauterization. A hysterometer was placed in the uterine cavity to respect the cervical canal and posterior uterine wall, and the myometrium was then closed in 2 layers. The total surgical time was 120 minutes. The postoperative period was uneventful. At 2 months after surgery, sonography confirmed restoration, with a myometrium thickness of 8.3 mm. The patient was asymptomatic, except for dyspareunia. At 6 months after surgery, hysteroscopic examination was normal. We recommended that the patient avoid attempting pregnancy for 9 months. CONCLUSION: Hysteroscopic simultaneous assistance during laparoscopic isthmocele repair can be of great help in identifying the edges of the defect, especially in large cavities and in first cases, in which edges might not be clear otherwise. Resecting all of the fibrotic tissue while respecting healthy myometrium is essential. Excessive cauterization and ischemic suturing could prevent proper healing of the myometrium.

RESUMO

Endometriosis is characterized by the abnormal presence of endometrium outside of the uterus, resulting in pelvic pain and infertility. The leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5) has been postulated to be a marker of stem cells in the endometrium. However, LGR5⁺ cells have a macrophage-like phenotype in this tissue, so it is unclear what role LGR5⁺ cells actually play in the endometrium. Macrophages serve an important function in the endometrium to maintain fertility, while LGR5⁺ cells generally have a role in tumor progression and are involved in invasion in some cancers. We sought to determine whether LGR5⁺ cells vary across the menstrual cycle in women with endometriosis and whether there are implications for LGR5 in the aggressiveness of endometriosis and reproductive outcomes. We performed immunofluorescence, flow cytometry, and primary culture in vitro experiments on eutopic and ectopic endometrium from healthy and endometriosis patients and observed that neither LGR5⁺ cells nor LGR5 expression varied throughout the cycle. Interestingly, we observed that LGR5⁺ cell percentage overexpressing CD163 (anti-inflammatory marker) was higher in healthy endometrium, suggesting that in endometriosis, endometrium presents a more pro-inflammatory phenotype that likely leads to poor obstetric outcomes. We also observed higher levels of LGR5⁺ cells in ectopic lesions compared to eutopic endometrium and specifically in deep infiltrating endometriosis, indicating that LGR5 could be involved in progression and aggressiveness of the disease.

RESUMO

Purpose: Basal cell carcinoma (BCC) is the most frequent malignant periocular tumor. It is associated with exposure to ultraviolet radiation, and its incidence is gradually increasing. It may occasionally display more aggressive behavior and result in orbital or intracranial invasion. Mortality from periocular BBC with orbital invasion is very low, but the associated morbidity can be significant, from disfigurement to blindness. Traditionally, these cases have been treated with orbital exenteration or with radiotherapy (RT), but in recent years, hedgehog pathway inhibitors (HPIs) have emerged, are effective in more serious cases, and are used primarily or combined with surgery, changing our perspective on the management of these patients. Methods: We studied 24 cases of periocular BCC with orbital invasion, some primary and others recurrent, which were treated between 2011 and 2021 in the same hospital. All patients had clinical or radiological evidence of orbital invasion. Orbital exenteration was performed on 9/24 of the patients (1 received vismodegib after surgery), and 12/24 were treated, surgically preserving the eyeball, with 3 of them receiving adjuvant vismodegib. Three of the twenty-four patients were treated exclusively with vismodegib (Erivedge®, Genentech). Results: One patient died due to poor tumor evolution, but the rest evolved favorably and they have had no recurrences. Vismodegib was generally well tolerated, except for in one patient who discontinued treatment due to the side effects. Conclusions: In advanced BBC with orbital invasion, mutilating surgical treatments such as exenteration or potentially vision-threatening treatments such as RT remain as options. In recent years, however, very promising new medical therapies have emerged, such as HPI, which can be used effectively instead of surgery or in combination with it, preserving the eye and vision, which implies a new approach to treatment.

RESUMO

Background: Effective domiciliary treatment can be useful in the early phase of COVID-19 to limit disease progression, and pressure on hospitals. There are discrepant data on the use of non-steroidal anti-inflammatory drugs (NSAIDs). Aim of this study is to evaluate whether the clinical outcome of patients who were hospitalized for COVID-19 is influenced by domiciliary treatment with NSAIDs. Secondary objective was to explore the association between other patient characteristics/therapies and outcome. Methods: A large dataset of COVID-19 patients was created in the context of a European Union-funded project (unCoVer). The primary outcome was explored using a study level random effects meta-analysis for binary (multivariate logistic regression models) outcomes adjusted for selected factors, including demographics and other comorbidities. Results: 218 out of 1,144 patients reported use of NSAIDs before admission. No association between NSAIDs use and clinical outcome was found (unadj. OR: 0.96, 95%CI: 0.68-1.38). The model showed an independent upward risk of death with increasing age (OR 1.06; 95% CI 1.05-1.07) and male sex (1.36; 95% CI 1.04-1.76). Conclusion: In our study, the domiciliary use of NSAIDs did not show association with clinical outcome in patients hospitalized with COVID-19. Older ages and male sex were associated to an increased risk of death.

RESUMO

BACKGROUND: Perfusion computed tomography (CT) is a rapid technique that allows the measurement of acute disturbances in local and global cerebral blood flow in patients suffering stroke and spontaneous subarachnoid haemorrhage (SAH). The purpose of this study was to establish the relationship between different measures of brain perfusion made on dynamic-contrast CT reconstructions performed as soon as SAH has been diagnosed and the severity of the bleeding determined by the clinical grade, the extent of the bleeding and the outcome of the patients. METHODS: After the diagnosis of SAH by conventional CT, a perfusion CT was performed before CT angiography. All imaging studies were performed on a six-slice spiral CT scanner. All images were analysed using perfusion software developed by Philips, which produces perfusion CT quantitative data based on temporal changes in signal intensity during the first pass of a bolus of an iodinated contrast agent. Measurements of mean transient time (MTT), time to peak (TTP), cerebral blood volume (CBV) and cerebral blood flow (CBF) in volumes of interest corresponding to territories perfused by the major cerebral arteries were performed. Different data regarding severity of the bleeding-such as level of consciousness, amount of bleeding in conventional CT-were collected. All poor-grade patients received a ventriculostomy catheter so that ICP recordings were obtained. Also, the occurrence of delayed cerebral ischaemia (DCI) was recorded. Outcome was assessed by the Glasgow Outcome Scale 6 months after the bleeding. For statistical analysis, non-parametric correlations between variables were performed. FINDINGS: Thirty-nine patients have been included in the study since January 2007. In SAH patients there are increasing perfusion abnormalities as the severity of the bleeding increases. The most affected perfusion parameters are TTP and MTT, as they significantly increase with the clinical severity of the bleeding and the total volume of bleeding (P < 0.01, Spearman's Rho). When average MTT time is increased over 5.9 s there is a 20-fold (95% CI = 2.1-182) risk of poor outcome. All patients presenting this MTT time suffered from DCI. This value has a positive predictive value of 100% for DCI and 90% for a poor outcome. CONCLUSIONS: SAH causes cerebral blood flow abnormalities even in the acute phase of the illness, consisting mainly of an increase in circulation times (TTP and MTT), which are correlated with the severity of the bleeding.

RESUMO

BACKGROUND: Iodine is an essential trace element implicated in synthesis of thyroid hormones. Iodine requirements vary throughout life. This iodine requirement is increased during pregnancy and breastfeeding. In a previous study carried out by our group in 2008, we detected an iodine-deficient area in the province of Huelva, specially in district Sierra de Huelva-Andévalo by means of neonatal TSH determinations. OBJECTIVE: To reinforce the iodine supplementation campaign and its impact on their newborns in order to assess nutrition iodine status in pregnant women using questionnaire and ioduria determination. MATERIAL AND METHODS: This study has been jointly carried out by Congenital Hypothyroidism Unit of the Clinical Biochemistry Department of the Virgen Macarena University Hospital (Seville) and the Gynecology and Clinical Analysis Unit of the Río Tinto Hospital (Huelva) during two years. We studied 313 pregnant women. All of them filled out a personal questionnaire to know the iodine nutritional status in their area. Ioduria was determinated by high-resolution liquid chromatography. Data from pregnant women and results of the studied variables were analyzed with SPSS v13.0. CONCLUSIONS: Pregnant women from the sanitary district Sierra de Huelva-Andévalo present a median for ioduria which corresponds to an insufficient iodine intake according to the WHO classification. The questionnaires suggest that this iodine deficiency is consequence of an insufficient iodine intake and a low adherence to the treatment.

RESUMO

BACKGROUND: Spontaneous bacterial peritonitis (SBP) remains a major complication of cirrhosis. However, the incidence and the real impact of SBP in determining patient survival rates remain unclear. This study aims to evaluate the incidence and risk factors for SBP development and the role of SBP in predicting transplant-free survival. METHODS: Two hundred two consecutive patients underwent 492 paracenteses with biochemical and microbiological analysis of the ascitic fluid. When multiple paracenteses had been performed on a given patient, the first SBP-positive paracentesis or the first paracentesis conducted when none was diagnostic for SBP was included in the study. RESULTS: SBP was detected in 28 of 202 (13.9%) patients; in 26 of 28 patients, the neutrophil count in the ascitic fluid was ≥250 cells/µl, and in 15 of 28 patients, the cultures were positive. Variables independently associated with SBP were as follows: a higher model of end-stage liver disease (MELD) score, the serum glucose value, elevated CRP serum levels, and higher potassium serum levels. Overall, the median (range) transplant-free survival was 289 (54-1253) days. One hundred (49.5%) patients died, whereas 35 patients (17.3%) underwent liver transplantation. Independent predictors of death or liver transplantation were a higher MELD score and the development of SBP, especially if it was antibiotic-resistant or recurrent SBP. CONCLUSION: The occurrence of SBP is associated with more severe liver dysfunction in conjunction with the presence of inflammation. Unlike the occurrence of SBP per se, failure of first-line antibiotic treatment and SBP recurrence appear to strongly influence the mortality rate.
