povidone-iodine and Pleural-Effusion--Malignant

Chemical pleurodesis is an important option for palliation in malignant pleural effusion (MPE).. To evaluate the status of iodopovidone for pleurodesis in MPE.. We performed a systematic review of PubMed and EMBASE databases to identify studies evaluating the role of iodopovidone for pleurodesis in MPE. We calculated the pooled success rate of iodopovidone pleurodesis from observational studies and the risk ratio (RR) of successful pleurodesis (compared to other agents) from randomized controlled trials (RCTs). We pooled the data using the random-effects model. We also assessed the safety of iodopovidone.. We included 26 studies (n = 1132, 15 observational, and 11 RCTs) in our review. The pooled success rate (95% confidence interval [CI]) from 15 observational studies (n = 648) was 90% (86-94). The efficacy rate of iodopovidone was similar with either tube thoracostomy or thoracoscopy. Eleven (n = 484) RCTs compared the efficacy of iodopovidone with other agents (especially bleomycin and talc). We found a similar success rate of iodopovidone compared to other agents with a pooled RR (95% CI) of 0.99 (0.91-1.08). The most frequent adverse event was chest pain. No hypo or hyperthyroidism, or visual disturbance was encountered in any study. There were no deaths attributed to iodopovidone use.. Iodopovidone is a safe and effective agent for pleurodesis in the management of MPE. Further confirmation is required since the available evidence is limited by the low quality and small sample size of the included studies.

Symptomatic pleural disease, specifically malignant pleural effusion, refractory benign pleural effusion, and pneumothoraces are common diseases that often require therapeutic interventions. The spectrum of management strategies often includes selection of a chemical pleurodesis agent administered in combination with an indwelling pleural catheter or chest tube.Additionally, there is a role for minimally invasive techniques which include medical thoracoscopy or more advanced video-assisted thoracoscopic approaches. Ongoing clinical trials continue to evolve best practices regarding the optimal sclerosant agents and procedural approaches in the management of these diseases.

The search for an inexpensive agent for chemical pleurodesis in malignant pleural effusion (MPE) continues. We aimed to compare the efficacy and safety of iodopovidone versus doxycycline for pleurodesis in MPE.. We randomized consecutive subjects with recurrent symptomatic MPE (1:1) to undergo pleurodesis with either doxycycline or iodopovidone administered through an intercostal tube. The primary outcome was the success rate of pleurodesis at 30 days. The secondary outcomes were the time to pleurodesis, chest pain (assessed using visual analog scale [VAS]) after pleurodesis, and complications (hypotension, acute respiratory failure, empyema).. We randomized 52 and 58 subjects to receive either doxycycline or iodopovidone. The mean (standard deviation [SD]) age of the study population (51% women) was 54.1 (13.6) years. Lung cancer (≥ 60%) was the most common underlying cause of MPE. We observed a similar frequency of success in the doxycycline vs. the iodopovidone group (complete response: 43 (82.7%) vs. 46 (79.3%) subjects; partial response: 7 (13.5%) vs. 10 (17.2%) subjects; p = 0.3). The mean (SD) time to pleurodesis was 1.5 (1.9) days and 1.9 (5.4) days in the doxycycline and iodopovidone groups, respectively. While the VAS for chest pain was significantly higher with iodopovidone (mean [SD] VAS: doxycycline, 31.9 [20.9]; iodopovidone, 41.3 [21.8]; p = 0.017), it did not reach the minimal clinically important difference. The complication rates were similar between the two groups.. Iodopovidone was not superior to doxycycline for pleurodesis in MPE.

malignant pleural effusion occurs as a consequence of a primary or metastatic malignant process involving the pleura. The aim of pleurodesis is to prevent re-accumulation of the effusion and avoid the need for repeated hospitalization. Povidone iodine has been used in other climes for pleurodesis with good results. The aim of this study is to assess the efficacy and safety of povidone iodine in producing pleurodesis as compared to tetracycline.. the study is a prospective experimental study. The patients are randomized into two groups A (tetracycline-control) and B (povidone iodine). All patients are assessed with chest X-ray after 1 week and 1 month. The responses were ascribed as complete, partial or failure.. thirty patients were recruited into this study, 15 patients in each group A (tetracycline) and B (povidone iodine). The mean age was 45.7±14.24 years. The commonest primary malignancy was Breast cancer (70%) followed by bronchogenic cancer (10%). Seventy three (73%) of the patients in this study had complete response and in 7% pleurodesis failed whilst 20% has partial response. In the povidone group the success rate was 93.4% and in the tetracycline group was 93.3% with a p-value of 0.716. There was no statistical difference in the responses based on the agents used.. malignant pleural effusion is a devastating condition as it heralds the end-of-life processes of a primary malignancy. Povidone iodine is a safe, cheap, effective, widely available and effective pleurodesing agent for use in patients with malignant pleural effusion.

Background Malignant pleural effusion continues to be a common problem in patients with metastatic disease. This study was conducted to compare the efficacy and safety of bleomycin pleurodesis with povidone-iodine pleurodesis through a chest drain as palliative treatment for recurrent malignant pleural effusion. Methods Sixty cancer patients (36 males and 24 females) with recurrent malignant pleural effusion were enrolled in a prospective randomized trial. Thirty patients received povidone-iodine pleurodesis and 30 received bleomycin pleurodesis. Age, sex, side of the primary pathology, treatment outcome (recurrence and relapse time), and complications were analyzed. Results The mean age was 59.63 ± 7.68 years in the povidone-iodine group and 57.97 ± 9.27 years in the bleomycin group ( p = 0.452). The complications were identical in both groups: 2 (6.7%) patients had chest pain, 2 (6.7%) had fever, and one (3.3%) had hypotension. There was a good response to therapy in 20 (66.7%) patients in the bleomycin group and 25 (83.3%) in the povidone-iodine group ( p = 0.136). Conclusion The results of this study indicate that povidone-iodine should be considered as a selective chemical agent to perform pleurodesis in patients with recurrent malignant pleural effusion because it has the same effect but costs less than bleomycin.

Malignant pleural effusions continue to be a common problem in patients with metastatic disease, leading to a significant reduction in quality of life with progressive dyspnea, dry cough, chest pain and reduced physical activity. This study was conducted to compare the efficacy, safety, and outcome of Talc Powder Pleurodesis (TPP) with Povidone-iodine Pleurodesis (PIP) through a chest drain as a palliative preventive treatment of recurrent malignant pleural effusion.. A total of 39 neoplastic patients with recurrent malignant pleural effusion were enrolled in a prospective randomized trial. Twenty-one patients received Talc pleurodesis (group A), and eighteen patients (group B) received Povidone-iodine pleurodesis. The continuous variables were expressed as mean values ± standard deviation (SD) and compared using the unpaired t-test. The discrete variables were expressed as percentage and compared using the chi-square test (χ(2)) test. p-values of less than 0.05 were considered significant.. Our study included 11 males and 28 females, the mean age was (71.0 ± 5.0) years for group A and (70.9 ± 5.1) years for group B (non-significant). Post-procedure analgesic requirements were recorded in both groups. Four patients in each group had fever (>38°C) within 48 hours of the procedure. Both groups achieved good symptomatic relief. There were no in-hospital deaths. The mean post-procedure hospital stay was (4.7 ± 1.2) days for group A and (4.2 ± 1.0) for group B (non-significant). At follow-up recurrence of significant pleural effusion requiring intervention was noted in four and five patients in group A and group B, respectively (non-significant difference).. Povidone-iodine pleurodesis can be considered as a good alternative to Talc pleurodesis for recurrent malignant pleural effusion. The drug is available, cost effective, safe and can be administered through an intercostal drain and repeated if necessary.

Iodopovidone is an alternative agent used to promote pleurodesis in patients with malignant pleural effusion (MPE). However, safety is a concern, and many authors still reject its use.. Our main objective is to describe the occurrence of common and severe adverse events after pleurodesis with two different doses of iodopovidone in patients with MPE. Our secondary objective is to evaluate dose dependency, efficacy, quality of life, and systemic inflammation.. We conducted a double-blind, randomized clinical trial including patients with recurrent MPE. Patients underwent chest tube insertion and were randomized into two groups according to the doses of iodopovidone: group 1 received 1% iodopovidone, and group 2 received 2% iodopovidone. During follow-up, adverse events, inflammatory markers, quality of life, and imaging exams were systematically evaluated and registered.. Sixty patients were analyzed (55 females, 5 males, median age 55.9 years). Overall, 227 adverse events possibly related to pleurodesis were registered, including 47 serious adverse events (in 34 patients). Pleuritic pain and hypertensive peaks were the most frequently observed serious adverse events (11 and 10 episodes, respectively). Grade 3/4 metabolic events such as hyponatremia and an increase in alkaline phosphatase, AST and ALT levels were also common. C-reactive protein (CRP) levels increased substantially and peaked 48 h after pleurodesis. No difference was observed between groups with regard to adverse events, CRP levels, efficacy, or quality of life.. Adverse events after iodopovidone pleurodesis in patients with MPE are common and similar in the two doses studied.

To compare the efficacy, safety, and outcome of thoracoscopic talc poudrage (TTP) versus povidone-iodine pleurodesis (PIP) through a thoracostomy tube as a palliative treatment of pleural effusion due to metastatic breast carcinoma (MBC).. A total of 42 MBC patients were prospectively enrolled in a randomized controlled trial. Twenty-two patients received TTP (group A), whereas 20 patients (group B) underwent pleurodesis by instilling povidone-iodine through a thoracostomy tube, as a bedside procedure.. The mean age was 48.2 ± 9.9 (range: 29-64) years and 50.2 ± 7 (range: 32-62) years for groups A and B, respectively (p=ns). At presentation, all patients had moderate to severe dyspnea, New York Heart Association (NYHA)>II and Medical Research Council (MRC) dyspnea scale 3-5. Morbidity in both groups was low. Post-procedure analgesic requirements due to severe pleuritic chest pain were higher in group A (18% vs 0%, p=0.2). Four patients in group A (18%) and one in group B (5%) were febrile (>38°C) within 48 h of the procedure. Both groups achieved good symptom control, with improvement in MRC dyspnea scale (1-3). There were no in-hospital deaths. Post-procedure hospital stay was lower in group B (p=0.009). The mean progression-free interval was 6.6 (range 3-15) months. At follow-up (mean: 22.6 (range: 8-48) months), recurrence of significant pleural effusion requiring intervention was noted in two and three patients in group A and group B, respectively (p=ns).. Povidone-iodine can be considered as a good alternative to TTP to ensure effective pleurodesis for patients with malignant pleural effusion due to MBC. The drug is available, cost effective and safe, can be given through a thoracostomy tube and can be repeated if necessary.

Malignant pleural effusion is a common complication in certain malignancies. Pleurodesis is the best option most of the time. The purpose of this study was to compare the choice of belomycin with povidone-iodine, which is not only determined by the efficacy of the agent but also by its cost, accessibility, safety, ease of administration and the number of administrations to achieve a complete response. We performed a randomized clinical trial on 39 patients presenting with symptomatic malignant pleural effusion. Patients were selected and randomly assigned to undergo chemical pleurodesis with either bleomycin or povidone-iodine. Primary characteristics of patients were assessed and graded before and after treatment concerning pain, dyspnea, and chest radiographs. A complete response was obtained in 79% of belomycin group and 75% of povidone-iodine group which was not statistically significant. Patients on belomycin treatment had a significantly lower score for dyspnea in one month follow up. This was significant after controlling for age, pain score and dyspnea score after drainage, using general linear model. Due to similar effect and significant cost advantage between bleomycin and povidone-iodine, we conclude that povidone- iodine is the agent of choice when utilizing pleurodesis for control of symptomatic malignant pleural effusions.

To evaluate the efficacy of iodopovidone as an agent for pleurodesis in malignant pleural effusion (MPE) and to compare the efficacy of small-bore catheter (Pleuracan, Braun, Melsungen, Germany) and conventional large-bore chest tube in pleural fluid drainage and sclerotherapy.. Patients with MPE were prospectively consecutively randomized into two groups between August 2004 and February 2007: pleurodesis via conventional (32F) chest tube (group 1) and small-bore catheter (group 2), both using iodopovidone. After 3 months' follow-up, response rates (complete or partial), complication rates, and duration of procedures within whole group, group 1, and group 2 were compared. Statistical analyses were performed by Mann-Whitney U, chi(2), and Fisher's exact test.. Forty-three pleurodeses were performed in 41 patients. The response was complete in 26 (60.5%) and partial in 12 (27.9%), and the overall success rate was 88.4%. The response rate was not associated with the type of inserted tube (P = .750), pleural fluid pH (P = .290), or pleural fluid lactate dehydrogenase (P = .727). In group 1 (n = 20), 12 demonstrated complete and 6 demonstrated partial response, with a 90% success rate; success was 86.9% in group 2, with complete response in 14 and partial response in 6 patients. Success rates were similar in the two groups (P = 1.000). Of 43 procedures, complications were observed in 14 (32.5%), and complication rates were 35% and 30.4% in groups 1 and 2, respectively (P = .750). The most frequent complication was pain (16.2%), followed by fever, subcutaneous emphysema, dyspnea, and hypotension.. Iodopovidone is an effective, inexpensive, safe, and easily available alternative in chemical pleurodesis in MPE. The success rates of pleurodesis were found to be similar regardless of the type of the tube inserted.

Malignant pleural effusions' (MPEs) treatment goals focus on optimizing the quality of life and decreasing time spent in health care facilities in this patient population with limited life expectancy. Numerous pleural palliation options and combination of these exist and continue to undergo studies to identify safe, superior and ideally patient-centered care. We report a cohort of 13 patients with symptomatic MPE managed with iodopovidone intrapleural instillation via an indwelling pleural catheter (IPC) in the ambulatory setting. Successful complete pleurodesis was achieved in 10 of 13 (76.9%) patients at a median time of 5 days with IPC removal at a median of 16 days. Two patient obtained partial pleurodesis with IPC removal, 1 required IPC reinsertion due to symptom recurrence. Complications were limited to intraprocedural pain in 4 patients (31%). Iodopovidone pleurodesis via IPC may represent a safe, feasible, and effective ambulatory-based option for pleural palliation in MPE.

Chemical pleurodesis is an important therapeutic tool to control recurrent malignant pleural effusion. Among the various sclerosing agents, iodopovidone is considered effective and safe. However, in a recent study, ocular changes were described after iodopovidone was used in recurrent pneumothorax. The aim of the study was to evaluate the efficacy and morbidity of iodopovidone pleurodesis in an experimental model.. New Zealand rabbits were submitted to intrapleural injection of iodopovidone at concentrations of 2%, 4% and 10%. Biochemical (lactic dehydrogenase, proteins, triiodothyronine, free thyroxine, urea and creatinine) and immunological (Interleukin-8 [IL-8], VEGF and TGFβ) parameters were measured in the pleural fluid and blood. After 1, 3, 7, 14 and 28 days, groups of animals were euthanized, and macro- (pleura) and microscopic (pleura and retina) analyses were performed.. An early pleural inflammatory response with low systemic repercussion was observed without corresponding changes in thyroid or renal function. The higher concentrations (4% and 10%) correlated with greater initial exudation, and maximum pleural thickening was observed after 28 days. No changes were observed in the retinal pigment epithelium of the rabbits.. Iodopovidone is considered to be an effective and safe sclerosing agent in this animal model. However, its efficacy, tolerance and safety in humans should be further evaluated.

Pleurodesis is one of the best methods of controlling malignant pleural effusions (MPE), a distressing complication of metastatic disease. In recent studies of a wide range of pleural diseases, iodopovidone was used as a sclerosing agent for pleurodesis and demonstrated good results with low morbidity. The aim of this study was to evaluate the efficacy and safety of iodopovidone pleurodesis in MPE.. A retrospective analysis was performed on patients with MPE who underwent pleurodesis at our institution between 2005 and 2008. All patients underwent instillation of 20 mL of 10% iodopovidone, 80 mL of normal saline and 2 mg/kg of lidocaine through a chest tube, which was clamped for 2 h. The tube was removed when the daily output of fluid was <200 mL. Data on the requirement for additional pleural procedures, adverse events and survival were collected.. Sixty-one pleurodesis procedures were performed in 54 patients. No procedure-related mortality was observed. Adverse events occurred after 11 (18%) pleurodesis procedures. The most frequent complication was mild thoracic pain that occurred immediately after 10 (16.4%) procedures, and one patient developed pleural empyema that was treated with drainage and antibiotics. A success rate of 98.4% was observed. Except for the patient who developed pleural empyema, none of the other patients had recurrences of pleural fluid or required additional pleural procedures during the follow-up period (mean of 5.6 months).. Iodopovidone pleurodesis was successful and was associated with only a few minor complications. It appears to be a good option for the management of recurrent MPE.

The management of recurrent pleural effusion or pneumothorax has always been a cause for serious concern among chest physicians. Among the wide variety of agents that are available for pleurodesis, povidone iodine is now perhaps the most sought after agent as it is cheap, easily available, effective and safe. This study was conducted to establish the efficacy and safety of povidone iodine as an agent for pleurodesis in patients with recurrent pleural effusion and pneumothorax.. A total of 38 consecutive patients with symptomatic malignant or recurrent pleural effusion and pneumothorax received povidone iodine for pleurodesis over a period of 18 months. The mean follow-up period was 10.2 months, with a standard deviation of 2.9 months.. Out of the 38 patients, 29 had malignant pleural effusion, eight had recurrent pneumothorax and one had tubercular pleural effusion which was nonresponsive to antitubercular therapy. A complete response with no recurrence during follow-up was obtained in 34 (89.5 percent) patients. All the cases of failure had malignant pleural effusion. Three (7.9 percent) patients experienced intense chest pains after the installation of sclerosing agent, but they recovered with immediate symptomatic management.. Recurrent pleural effusion or pneumothorax due to any cause may be managed effectively and safely by chemical pleurodesis with povidone iodine. It may be considered as the agent of choice to achieve pleurodesis, especially in resource constrained countries like India, as it is inexpensive and easily available.

Pleurodesis is considered as the best palliative therapy for the treatment of symptomatic malignant pleural effusion. Several chemical agents are used for this purpose with variable efficacy and safety. The present study is to compare the effectiveness and safety of talc and povidone iodine as chemical agents for pleurodesis in patients of malignant pleural effusion. Fifty-two patients with malignant pleural effusion admitted in the department of chest of Calcutta National Medical College, Kolkata were selected for the study. Pleurodesis with povidone iodine and talc in slurry was done in 28 and 24 patients respectively. Efficacy and safety of these agents were assessed during a follow-up period of six months. Among the 52 patients, 42 were males and 10 females. Age ranged from 40 to 64 years with mean age of 56.4 years. In 41 patients effusion was secondary to bronchogemic carcinoma, 8 had effusion secondary to breast carcinoma, 1 had effusion due to non-Hodgkin's lymphoma, while primary malignancy was unknown in 2 patients. Among the 24 patients treated with talc pleurodesis, 20 had bronchogenic carcinoma, 3 had breast carcinoma and 1 had unknown primary malignancy. Out of the 28 patients treated with povidone iodine pleurodesis, bronchogenic carcinoma was present in 21 patients, breast carcinoma in 5 patients, non-Hodgkin's lymphoma and unknown primary malignancy was present in 1 patient each. Pleurodesis with talc showed complete success in 19 patients, partial success in 3 patients and failure in 2 patients. Pleurodesis with povidone iodine showed complete response in 24 patients, partial response in 1 patient and failure in 3 patients. Chest pain occurred in 4 patients of talc pleurodesis and 5 patients of povidone iodine pleurodesis, 3 patients of each group had fever. There was no death in the peripleurodesis period. During the 6 months follow-up, 12 patients of talc pleurodesis and 18 patients of povidone iodine pleurodesis died. Talc is slurry and povidone iodine is equally effective and safe pleurodesing agent for symptomatic malignant pleural effusion. However povidone iodine can be preferred option because of easy availability and low cost.

The authors present 15 patients with proven malignant pleural effusion who underwent pleurodesis with Povidone. They obtained a complete response in 100% of the cases. The average duration of the response was 23.3 weeks ranging from 3 to 83 weeks. Seven patients are alive and on follow up with an average response time of 30 weeks. Six patients are dead, with an average response time of fifteen weeks. We don't know the late results in 2 patients after the control (4 weeks after treatment). The pleural tube remained in place from 2 to 8 days. There were no untoward or colateral effects in these patients. The cost of the Povidone utilized was B/0.40 per patient. The cost, the efficacy and the absence of ill effects make Povidone the agent of choice in the palliative treatment of malignant pleural effusion.
