ABSTRACT
OBJECTIVE@#To investigate the efficacy and safety of intravesical instillation of heparin/alkalized lidocaine (lidocaine mixed with sodium bicarbonate) combined with hydrodistension and transurethral fulguration in the treatment of female interstitial cystitis (IC).@*METHODS@#Female patients who attended the Department of Urology at the First Hospital of China Medical University between January 2012 and December 2020 and met the diagnostic criteria proposed in the guidelines of the American Urological Association with a new diagnosis of IC were selected for retrospective analysis. Cystoscopy and biopsy of suspicious lesions were performed at the time of diagnosis. All the patients were treated with an intravesical instillation regimen of 2% lidocaine 10 mL + 5% sodium bicarbonate 5 mL + heparin 25 000 IU for a continuous period of 12 months, with or without water dilatation and transurethral electrocautery according to the patient's preference, categorized as hydrodistension and transurethral fulguration (HD/TF) group and non-HD/TF group. The patients were evaluated before and 1, 6, and 12 months after treatment for O'Leary-Sant interstitial cystitis patient symptom index scores (ICSI), interstitial cystitis patient problem index scores (ICPI), visual analog scale (VAS) of suprapubic pain, and functional bladder capacity (FBC) changes.@*RESULTS@#A total of 79 patients were collected in this study. Four (5.1%) of these patients underwent cystectomy due to pathological diagnosis of cancer or treatment failure. The remaining patients were followed up 1, 6 and 12 months after treatment. Repeated-measures ANOVA showed a significant decrease in ICPI, ICSI and VAS and an increase in FBC after treatment compared with before treatment (P < 0.05). FBC continued to decrease during the 1, 6 and 12 months' post-treatment follow-ups, with statistically significant differences; ICSI continued to decrease during the 1 and 6 months post-treatment follow-ups, with statistically significant differences, while the difference between ICSI at 6 months post-treatment and at 12 months' post-treatment was not statistically significant. In the HD/TF group, ICPI continued to decrease in the follow-up from 1 and 6 months after treatment, and the difference was statistically significant, while the difference between ICPI 6 months after treatment and 12 months after treatment was not statistically significant. There was no statistically significant difference between the remaining indicators 1, 6 and 12 months after treatment. ICPI, ICSI, VAS and FBC improved earlier and the changes in VAS and FBC were more significant in the HD/TF group compared with the non-HD/TF group (P < 0.05).@*CONCLUSION@#Heparin/alkalized lidocaine combination of intravesical instillation with hydrodistension and transurethral fulguration for IC is an effective treatment option. Heparin/alkalized lidocaine combination of intravesical instillation may be the first choice of treatment, which can significantly reduce the economic burden of patients and medical insurance system. If patients can accept it, transurethral fulguration with hydrodistension may be considered.

ABSTRACT Objective: To evaluate the effect of intravesical hyaluronic acid (HA) treatment on inflammatory cells and the severity of inflammation in an interstitial cystitis rat model created with hydrogen chloride (HCL) via immunohistochemical studies and myeloperoxidase activity for the first time in the literature. Materials and Methods: A total of 30 adult female white Rattus Norvegicus rats were divided into 3 groups as the HCL group, hyaluronic acid treatment (HCL-HA) group and control group. Chemical cystitis was created by administering HCL(400 microL,10 mM) except control group. A single dose of intravesical HA(0.5 mL,0.8 mg/mL) was administered to the treatment group. The bladder tissues of all subjects were immunohistochemically stained. The cell surface markers were used to evaluate inflammatory cell infiltration. Mast cell activation and IL-6 was evaluated to assess the inflammation and severity of inflammation, respectively. Myeloperoxidase activity was measured as it shows neutrophil density. Statistical significance was accepted as P<0.05. Results: It was observed that there was rich monocyte, T lymphocyte, B lymphocyte, and Natural Killer cells infiltration and high IL-6 levels in the bladder tissue after the intravesical hydrogen chloride instillation, especially in the stroma layer(p<0.005). In the HCL-HA group, severity of inflammation had statistically significantly regressed to the levels of the control group(p<0.005). An increase was observed in the bladder myeloperoxidase activity of the HCL group compared to the other two groups(p<0.05). Conclusions: Single dose intravesical hyluronic acid instillation reduces inflammatory cell infiltration and the severity of bladder inflammation in the rat model of bladder pain syndrome/interstitial cystitis.

Abstract Interstitial cystitis (IC), including bladder pain syndrome (BPS), is a chronic and debilitating disease thatmainly affectswomen. It is characterized by pelvic pain associated with urinary urgency, frequency, nocturia and negative urine culture,with normal cytology. In 2009, the Society for Urodynamics and Female Urology (SUFU) defined the term IC/BPS as an unpleasant sensation (pain, pressure, and discomfort) perceived to be related to the urinary bladder, associated with lower urinary tract symptoms for more than 6 weeks duration, in the absence of infection or other identifiable causes. This is the definition used by the American Urological Association (AUA) in the most recent guidelines on IC/BPS. Interstitial cystitis may be sufficiently severe to have a devastating effect on the quality of life, but it may also be associated with moderate symptoms whose effects are less debilitating. Although there are several clinical trials to assess oral and intravesical therapies, the treatment for IC remains far from ideal. This systematic assessment evaluates published randomized clinical trials on oralmedications used totreat symptoms of BPS. This studywas performed according to the preferred reporting items for systematic reviews and metaanalyses (PRISMA)method. Two independent reviewers screened the studies to determine their inclusion or exclusion and to perform the methodological analysis. The inclusion criteria included randomized studiespublishedbetween April of 1988and April of2016 that used oral medications to treat symptoms of BPS or IC. According to the systematic review performed,we should consider pentosan polysulfate as one of the bestoptions of oral drugs for the treatment of BPS symptoms. However, this drug is not an available option in Brazil. Orally administered amitriptyline is an efficacious medical treatment for BPS, and it should be the first treatment offered.
Resumo Cistite intersticial (IC), incluindo a síndrome da bexiga dolorosa (SBD), é uma doença crônica e debilitante que afeta principalmente mulheres. É caracterizada por dor pélvica associada à urgência miccional, frequência urinária, noctúria e exame cultural de urina negativo, com citologia normal. A cistite intersticial pode ser suficientemente severa para ter um efeito devastador na qualidade de vida, mas também pode estar associada a sintomas moderados e menos debilitantes. Embora existam vários ensaios clínicos para avaliar terapias orais e intravesicais, o tratamento para IC permanece longe do ideal. Esta revisão sistemática avaliou ensaios clínicos randomizados publicados sobre medicamentos orais usados para tratar sintomas de SBD. Este estudo foi realizado de acordo com ométodo preferred reporting items for systematic reviews and meta-analyses (PRISMA). Dois revisores independentes examinaram os estudos para determinar sua inclusão ou exclusão e para realizar a análise metodológica. Os critérios de inclusão foram: ensaios clínicos randomizados publicados entre abril de 1988 e abril de 2016 que usaram medicações orais no tratamento dos sintomas da SBD ou CI. De acordo com a revisão sistemática realizada, a melhor opção de medicação oral para o tratamento dos SBD é o pentosano polissulfato sódico. No entanto, esta droga não está disponível no Brasil. A amitriptilina administrada por via oral é um tratamento eficaz para SBD e deve ser oferecida como primeira escolha.

ABSTRACT Objective To compare effectiveness of intravesical chondroïtin sulphate (CS) 2% and dimethyl sulphoxide (DMSO) 50% in patients with painful bladder syndrome/interstitial cystitis (PBS/IC). Materials and methods Patients were randomized to receive either 6 weekly instillations of CS 2% or 50% DMSO. Primary endpoint was difference in proportion of patients achieving score 6 (moderately improved) or 7 (markedly improved) in both groups using the Global Response Assessment (GRA) scale. Secondary parameters were mean 24-hours frequency and nocturia on a 3-day micturition dairy, changes from baseline in O’Leary-Sant questionnaire score and visual analog scale (VAS) for suprapubic pain. Results Thirty-six patients were the intention to treat population (22 in CS and 14 in DMSO group). In DMSO group, 57% withdrew consent and only 6 concluded the trial. Major reasons were pain during and after instillation, intolerable garlic odor and lack of efficacy. In CS group, 27% withdrew consent. Compared with DMSO group, more patients in CS group (72.7% vs. 14%) reported moderate or marked improvement (P=0.002, 95% CI 0.05-0.72) and achieved a reduction in VAS scores (20% vs. 8.3%). CS group performed significantly better in pain reduction (-1.2 vs. -0.6) and nocturia (-2.4 vs. -0.7) and better in total O’Leary reduction (-9.8 vs. -7.2). CS was better tolerated. The trial was stopped due to high number of drop-outs with DMSO. Conclusions Intravesical CS 2% is viable treatment for PBS/IC with minimal side effects. DMSO should be used with caution and with active monitoring of side effects. More randomized controlled studies on intravesical treatments are needed.

Cervical and intracranial arterial evaluation is an important issue for acute ischemic stroke (IS). Objective Compare the use of the neurovascular ultrasound examination (NVUE) to digital subtraction angiography (DSA) in acute IS patients for diagnosing significant extracranial and intracranial arteriopathy. Method Nonconsecutive patients with IS or transient ischemic attack admitted within 12 hours of the onset of symptoms were evaluated retrospectively. Standardized NVUE and DSA were done in all patients within the first 120 hours of hospital admission. Results Twenty-four patients were included in the study. Compared to DSA, the NVUE demonstrated 94.7% sensitivity and 100% specificity for identifying symptomatic extracranial and/or intracranial arteriopathy. Conclusion The standardized NVUE technique demonstrated high sensitivity and specificity compared to DSA for diagnosing arterial abnormalities in acute IS patients. .

La cistitis intersticial se define como un síndrome clínico caracterizado por un incremento de la frecuencia urinaria, urgencia miccional y/o dolor abdominal o perineal en ausencia de infección urinaria o enfermedad conocida del aparato urinario. Se divide de acuerdo a los hallazgos citoscópicos en ulcerativa o no. La base del diagnóstico es clínica apoyada en scores de probabilidad y pruebas invasivas. Con la comprensión de la fisiopatología se ha desarrollado un abanico de posibilidades terapéuticas. Comunicamos el caso de una paciente sintomática por cuatro años con diagnóstico de cistitis intersticial con úlcera de Hunner por cistoscopia y excelente respuesta a la amitriptilina. Es una enfermedad que produce considerable alteración de la calidad de vida, por lo que es importante que los médicos estén familiarizados con este cuadro.
Interstitial cystitis is characterized by over 6 months of chronic pain, pressure and discomfort felt in the lower pelvis or bladder. It is often relieved with voiding, along with daytime frequency and nocturia in the absence of an urinary tract infection. The disorder can be divided clinically into two groups -ulcerative and non-ulcerative- based on cystoscopic findings and response to treatment. Management follows an approach of applying the least invasive therapy that affords sufficient relief of symptoms. We report a case of a patient with interstitial cystitis. The diagnosis was performed by symptoms and lesion in the cystoscopy and excellent response to amitriptyline.

PURPOSE: We reproduced a non-bacterial experimental model to assess bladder inflammation and urinary glycosaminoglycans (GAG) excretion and examined the effect of dimethyl sulfoxide (DMSO). MATERIALS AND METHODS: Female rats were instilled with either protamine sulfate (PS groups) or sterile saline (control groups). At different days after the procedure, 24 h urine and bladder samples were obtained. Urinary levels of hyaluronic acid (HA) and sulfated glycosaminoglycans (S-GAG) were determined. Also to evaluate the effect of DMSO animals were instilled with either 50 percent DMSO or saline 6 hours after PS instillation. To evaluate the effect of DMSO in healthy bladders, rats were instilled with 50 percent DMSO and controls with saline. RESULTS: In the PS groups, bladder inflammation was observed, with polymorphonuclear cells during the first days and lymphomononuclear in the last days. HA and S-GAG had 2 peaks of urinary excretion, at the 1st and 7th day after PS injection. DMSO significantly reduced bladder inflammation. In contrast, in healthy bladders, DMSO produced mild inflammation and an increase in urinary HA levels after 1 and 7 days and an increase of S-GAG level in 7 days. Animals instilled with PS and treated with DMSO had significantly reduced levels of urinary HA only at the 1st day. Urinary S-GAG/Cr levels were similar in all groups. CONCLUSIONS: Increased urinary levels of GAG were associated with bladder inflammation in a PS-induced cystitis model. DMSO significantly reduced the inflammatory process after urothelial injury. Conversely, this drug provoked mild inflammation in normal mucosa. DMSO treatment was shown to influence urinary HA excretion.
