Post bar removal results of pectus deformity patients who underwent minimally invasive correction.

Introduction: The most common chest wall deformities are pectus excavatum and pectus carinatum. Surgical repair of these deformities via minimally invasive technique using pectus bars is commonly preferred by numerous thoracic surgeons. Despite this common choice for treatment, the duration of the bar stay, the bar removal process, the possible complications and ways to prevent them have been debated over the years and still there is no single decision. Aim: To determine the decision making, surgical outcomes and negative factors in the bar removal process. Material and methods: There were 1032 patients underwent bar removal between 2006-2020 and their data was recorded prospectively. We analyzed patients' demographics, family history, Haller index, bar count, body mass index, stabilizer and wire usage, length of hospital stay, time until bar removal, incision side and complications retrospectively. Results: There was no significant correlation between BMI and surgery time (p = 0.748). There was no statistically significant correlation between the age groups and the number of pectus bars removed. The other factors showed no significant difference. The surgery time was found to be significantly longer in those with callus tissue (p = 0.002). Conclusions: These findings suggest that pectus bars can be left in place for a shorter time than the standard 3-year interval without any additional recurrence risk and without compromising quality of life. As a result, patients with persistent pain after pectus repair should be well evaluated for the possibility of life-threatening complications during bar removal.

Can postoperative complications be reduced by the application of ERAS protocols in operated non-small cell lung cancer patients?

Background: In our study, we aimed to evaluate the length of hospital stay and complication rate of patients before and after application o f t he E nhanced R ecovery A fter S urgery ( ERAS) protocols. Methods: Between January 2001 and January 2021, a total of 845 patients (687 males, 158 females; mean age: 55±11 years; range, 19 to 89 years) who were operated with the diagnosis of non-small cell lung carcinoma were retrospectively analyzed. The patients were divided into three groups as follows: patients between 2001 and 2010 were evaluated as pre-ERAS (Group 1, n=285), patients between 2011 and 2015 as preparation for ERAS period (Group 2, n=269), and patients who had resection between 2016 and 2021 as the ERAS period (Group 3, n=291). Results: All three groups were similar in terms of clinical, surgical and demographic characteristics. Smoking history was statistically significantly less in Group 3 (p=0.005). The forced expiratory volume in 1 sec/forced vital capacity and albumin levels were statistically significantly higher in Group 3 (p<0.001 and p=0.019, respectively). The leukocyte count and tumor maximum standardized uptake value were statistically significantly higher in Group 1 (p=0.018 and p=0.014, respectively). Postoperative hospitalization day, complication rate, and intensive care hospitalization rates were statistically significantly lower in Group 3 (p<0.001). The rate of additional disease was statistically significantly higher in Group 1 (p=0.030). Albumin level (<2.8 g/dL), lymphocyte/monocyte ratio (<1.35), and hemoglobin level (<8.3 g/dL) were found to be significant predictors of complication development. Conclusion: With the application of ERAS protocols, length of postoperative hospital stay, complication rate, and the need for intensive care hospitalization decrease. Preoperative hemoglobin level, albumin level, and lymphocyte/monocyte ratio are the predictors of complication development. Increasing hemoglobin and albumin levels before operation may reduce postoperative complications.

Combined Repair of Upper Sternal Cleft and Pectus Excavatum in a Child.

Sternal cleft accompanied by pectus excavatum is a rare type of congenital anomaly of the chest wall. Surgical correction is a suitable approach to restore the heart, large vessels, and respiratory dynamics early. This is a report of the successful surgical correction of upper sternal cleft anomaly accompanied by pectus excavatum in a child. The pectus excavatum was corrected without the use of any prosthesis. The cleft was closed by primary approximation with enough dissected pectoralis major muscle and partial thymectomy, mobility, and flexibility ensured by pectus correction. The integrity of the sternum and the chest wall was normal at the end of the 12-month follow-up period.

Dysregulation of E-cadherin in pulmonary cell damage related with COPD contributes to emphysema.

Air pollution, especially at chronic exposure to high concentrations, is a respiratory risk factor for the development of chronic obstructive pulmonary disease (COPD). E-cadherin, a cell-cell adhesion protein, is involved in the integrity of the alveolar epithelium. Causes of E-cadherin decreases in emphysematous areas with pulmonary cell damage related to COPD are not well understood. We aimed to determine the molecules causing the decrease of E-cadherin and interactions between these molecules. In emphysematous and non-emphysematous areas of lungs from COPD patients (n = 35), levels of E-cadherin, HDACs, Snail, Zeb1, active-ß-catenin, p120ctn, and Kaiso were determined by using Western Blot. The interactions of HDAC1, HDAC2, and p120ctn with transcription co-activators and Kaiso were examined by co-immunoprecipitation experiments. The methylation status of the CDH1 promoter was investigated. E-cadherin, Zeb1, Kaiso, and active-ß-catenin were decreased in emphysema, while HDAC1, HDAC2, and p120ctn2 were increased. Snail, Zeb1, Twist, active-ß-catenin, Kaiso, and p120ctn co-precipitated with HDAC1 and HDAC2. E-cadherin, Kaiso, and active-ß-catenin co-precipitated with p120ctn. HDAC1-Snail and HDAC2-Kaiso interactions were increased in emphysema, but p120ctn-E-cadherin interaction was decreased. The results show that HDAC1-Snail and HDAC2-Kaiso interactions are capable of decreasing the E-cadherin in emphysema. The decreased interaction of p120ctn/E-cadherin leads to E-cadherin destruction. The decreased E-cadherin and its induced degradation in pneumocytes cause impaired repair and disintegrity of the epithelium. Approaches to suppress HDAC1-Snail and HDAC2-Kaiso interactions may help the protection of alveolar epithelial integrity by increasing the E-cadherin stability in pneumocytes.

Downregulation of TCEAL7 expression induces CCND1 expression in non-small cell lung cancer.

Transcription Elongation Factor A-like 7 (TCEAL7) was first reported as a candidate tumor suppressor gene because of its inactivation in ovarian cancer as a result of promoter methylation. Down-regulation of the TCEAL7 gene expression was also associated with other cancers such as endometrial, breast, brain, prostate, gastric cancers, glioblastoma and linked to tumor phenotypes and clinical outcomes. However, there is no report in the literature investigating the role of TCEAL7 in non-small cell lung cancer. Cyclin D1 is an important molecule in the transition from G1 to S phase of the cell cycle, and is frequently deregulated in cancers. Cylin D1 (CCND1) gene is amplified or overexpressed in a variety of tumors. In our previous study we reported that CCND1 over-expression was not associated with amplification in non-small cell lung cancer. Recently, it has been reported that TCEAL7 regulates CCND1 expression through myc-binding E-box sequences. The aim of this study was to investigate the expression of TCEAL7 gene in non-small cell lung cancer and to determine its effect on the CCND1 expression level. For this purpose, expression levels of TCEAL7 and CCND1 genes were investigated in 50 patients with non-small cell lung cancer by quantitative real time polymerase chain reaction (qRT-PCR). TCEAL7 was under-expressed (68%) in non-small cell lung cancer tumor tissues while CCND1 was over-expressed (42%). The TCEAL7 levels negatively correlated with increased CCND1 expression (p = 0.002).

Thoracoscopic removal of ectopic mediastinal parathyroid adenoma causing hyperparathyroidism: a rare entity.

Ectopic mediastinal parathyroid adenomas are uncommon. Here, we report the successful thoracoscopic removal of a mediastinal parathyroid adenoma from a patient with hypercalcemia. A 58-year-old female patient was referred to our department with persistent hypercalcemia. Serum calcium and phosphorus levels were 13.2 mg/dl and 2.5 mg/dl respectively, while the intact parathormone level was 798.9 pg/ml. Parathyroid computed tomography revealed a solid and well-defined mass at the anterior mediastinum close to the distal aorta. Once the contrast was enhanced, our pre-diagnosis was ectopic parathyroid adenoma. The mass was detected at the anterior mediastinum, dissected free from the surrounding tissue and excised. The capsulated mass, which had a diameter of 3 × 1.5 × 0.7 cm, was confirmed as parathyroid adenoma histopathologically. Postoperative calcium and parathormone levels decreased dramatically to normal levels. Anterior mediastinal localization of an ectopic parathyroid adenoma is a rare entity. The transsternal approach is the most preferred method, but video-thoracoscopy can be used safely and effectively.

Comparative study of video-assisted thoracoscopic surgery versus open thymectomy for thymoma and myasthenia gravis.

INTRODUCTION: Thymectomy is the preferred standard treatment in younger non-thymoma patients with myasthenia gravis as well as in patients with early stage thymoma. Total thymectomy by median sternotomy has been the surgical approach since resection of the thymus with video-assisted thoracoscopic surgery (VATS). AIM: To compare the clinical outcomes of VATS thymectomy with conventional open thymectomy for neoplastic and non-neoplastic thymic diseases. MATERIAL AND METHODS: Forty patients underwent thymectomy between October 2012 and January 2016. Fifteen patients were male and 25 patients were female. The mean age was 40.3 ±17.7 years. Seventeen (55%) patients underwent VATS thymectomy and 23 (45%) patients underwent an open procedure. We retrospectively reviewed the data of the patients and compared these two techniques. RESULTS: The mean tumor size was 5.17 ±3.2 cm in the thymoma group (VATS 2.5 ±2.4 cm vs. open access 4.7 ±3.7 cm). None of the patients experienced a myasthenic crisis. Conversion to thoracotomy was required in 1 patient in the VATS group due to bleeding from the right internal mammary artery; therefore, the conversion rate was 2.5% among all the patients. No mortality occurred in either group. No significant difference was found in the perioperative blood loss, operative time or pain visual analogue scale scores. On the other hand, regarding postoperative drainage, duration of chest tube drainage and length of hospital stay, VATS thymectomy yielded better results and the differences were significant. CONCLUSIONS: Video-assisted thoracoscopic surgery thymectomy can be performed for both neoplastic and non-neoplastic thymic diseases with minimal morbidity and mortality.

Minimally invasive injection laryngoplasty in the management of unilateral vocal cord paralysis after video-assisted mediastinal lymph adenectomy.

INTRODUCTION: Video-assisted mediastinal lymphadenectomy (VAMLA) is a valuable tool for invasive staging of the mediastinum. Unilateral vocal cord paralysis (UVCP) may occur in patients following VAMLA and may result in secretion retention within the lungs, atelectasis and associated infectious situations such as pneumonia. Minimally invasive injection laryngoplasty (ILP) is the treatment of choice in UVCP. AIM: To evaluate the efficacy and success of acute minimally invasive injection laryngoplasty for patients with UVCP following VAMLA. MATERIAL AND METHODS: Patients with the symptom of dysphonia following VAMLA were reviewed. All of the patients had UVCP according to the video laryngoscopy examination and had symptoms of aspiration and ineffective coughing. The Voice Handicap Index (VHI) questionnaire and maximum phonation time (MPT) were measured. Minimally invasive ILP was performed under general anesthesia with 1 cm of hyaluronic acid. RESULTS: There were 525 consecutive non-small cell lung cancer (NSCLC) patients who underwent VAMLA. Five (0.95%) of the patients had UVCP and were suffering from aspiration during oral intake and ineffective coughing reflex. Maximum phonation time (MFT) was measured before and after ILP, and the results were 7.1 ±1.6 and 11.1 ±2.3 s, respectively (p < 001). The Voice Handicap Index-10 (VHI-10) score was 30.4 ±4.7 and 13.4 ±3.5 (p < 0.01), respectively. Patients underwent surgical lung resection. There was no morbidity or mortality. CONCLUSIONS: Unilateral vocal cord paralysis may occur as a complication of VAMLA. ILP may be an active tool for treating UVCP before anatomical lung resection to avoid potential morbidities. Successful management of this complication with multidisciplinary team work may encourage the use of VAMLA more frequently.

Uniportal versus multiport video-assisted thoracoscopic surgery for anatomical lung resections: a glance at a dilemma.

INTRODUCTION: As the number of operations performed by videothoracoscopy is increasing, there is also a tendency to decrease the number of port incisions. Apart from the reduced number of surgical incisions, there are a few reports and systematic reviews that demonstrate some potential advantages of the uniportal video-assisted thoracoscopic surgery, but the impact of the reduced incisions in the clinical setting still remains uncertain. AIM: To compare uniportal video-assisted thoracoscopic surgery to multiport video-assisted thoracoscopic surgery for anatomical lung resections in patients with malignant and benign lung diseases. MATERIAL AND METHODS: From August 2010 to April 2016, a total of 102 patients with malignant and benign lung diseases underwent videothoracoscopic lobar and sublobar lung resections in our department. Comorbidities, tumor stage, tumor localization, mortality, operative time, pain visual analogue scale, length of hospital stay, perioperative blood loss, duration and amount of postoperative drainage and air leak, number of harvested lymph nodes and complication rates were analyzed. RESULTS: No significant difference was found in the duration of chest tube drainage, pain visual analogue scale score, length of hospital stay, perioperative blood loss, amount of postoperative drainage, number of harvested lymph nodes or complication rate. There was no surgical mortality in either of the two groups. However, operative time was shorter (189 min vs. 256 min, p < 0.005) in the multiport group than in the uniportal group. CONCLUSIONS: Compared with the uniportal approach, the multiport approach is associated with a significantly shorter operative time in our study.

Validity of the updated European Society of Thoracic Surgeons staging guideline in lung cancer patients.

OBJECTIVE: The European Society of Thoracic Surgeons (ESTS) has proposed a revised preoperative lymph node staging guideline for patients with potentially resectable non-small cell lung cancer (NSCLC). We aimed to assess the validity of this revised ESTS guideline and survival results in our patient cohort. METHODS: A total of 571 patients with potentially resectable NSCLC seen between January 2004 and November 2013 were included in the study. The preoperative mediastinal staging was performed by video-assisted cervical mediastinoscopy or video-assisted mediastinoscopic lymphadenectomy in all patients except those with peripheral cT1N0 nonadenocarcinoma tumors. Resection via thoracotomy or video-assisted thoracoscopic surgery was done in patients with no mediastinal lymph node metastasis. Surgical pathological results were compared with the ESTS staging guideline, and the validity of the guideline was tested. RESULTS: In this series, mediastinal lymph node metastasis was revealed preoperatively in 266 patients (46.6%). A total of 305 patients underwent anatomic lung resection. The sensitivity, specificity, positive and negative predictive values, and accuracy of the guidelines were calculated as 95.0%, 100%, 100%, 94.6%, and 97.2%, respectively. CONCLUSIONS: The ESTS revised preoperative lymph node staging guidelines for patients with NSCLC seem to be effective and valid, and may provide high survival following resectional surgery.

A prospective randomized trial comparing homologous and autologous fibrin sealants for the control of alveolar air leak.

BACKGROUND: Postoperative air leak is a common complication seen after pulmonary resection. It is a significant reason of morbidity and also leads to greater hospital cost owing to prolonged length of stay. The purpose of this study is to compare homologous sealant with autologous one to prevent air leak following pulmonary resection. METHODS: A total of 57 patients aged between 20 and 79 (mean age: 54.36) who underwent pulmonary resection other than pneumonectomy (lobar or sublobar resections) were analyzed. There were 47 males (83%) and 10 females (17%). Patients who intraoperatively had air leaks were randomized to receive homologous (Tisseel; n=28) or autologous (Vivostat; n=29) fibrin sealant. Differences among groups in terms of air leak, prolonged air leak, hospital stay, amount of air leak were analyzed. RESULTS: Indications for surgery were primary lung cancer in 42 patients (71.9%), secondary malignancy in 5 patients (8.8%), and benign disease in 10 patients (17.5%). Lobectomy was performed in 40 patients (70.2%), whereas 17 patients (29.8%) had wedge resection. Thirteen (46.4%) patients developed complications in patients receiving homologous sealant while 11 (38.0%) patients had complication in autologous sealant group (P=0.711). Median duration of air leak was 3 days in two groups. Time to intercostal drain removal was 3.39 and 3.38 days in homologous and autologous sealant group respectively (P=0.978). Mean hospital stay was 5.5 days in patients receiving homologous sealant whereas it was 5.0 days in patients who had autologous agent (P=0.140). There were no significant differences between groups in terms of measured maximum air leak (P=0.823) and mean air leak (P=0.186). There was no significant difference in the incidence of complications between two groups (P=0.711). CONCLUSIONS: Autologous and heterologous fibrin sealants are safe and acts similarly in terms of air leak and hospital stay in patients who had resectional surgery.

Single port thoracoscopic treatment of thoracic duct injury after thyroidectomy with neck dissection.

Chylous leakage is a complication of thyroidectomy accompanied by bilateral neck dissection with incidence of 0.5-6.2%. A 51-year-old female patient underwent total thyroidectomy, bilateral and central neck dissection for papillary thyroid carcinoma. In post-operative 4th day, left sided chylous leakage was observed as 1,500 cc/day through neck drain. Leakage did not cease after 1-month conservative treatment so single port thoracoscopic intervention was performed. Under general anesthesia, patient was placed in left lateral decubitus position. An Alexis® retractor was placed through sixth intercostal space. Thoracic cavity was visualized with 30º scope. Posteroinferior edge of lower lobe was retracted superior posteriorly with a Foerster clamp to display inferior pulmonary ligament, which was then divided with electrocautery. Posterior mediastinal pleura between azygous vein and chest wall was incised to mobilize the vein. After that, mediastinal pleura between azygous vein and esophagus was cut longitudinally and esophagus was retracted anteriorly to dissect towards aorta. By dissection, thoracic duct was revealed as a thin tubular structure with occasional peristalsis. After isolation of the duct, it was clipped using Hem-o-lok®. Finally, fibrin sealant was applied to decrease risk of recurrence. One chest tube was placed to ensure adequate drainage of thoracic cavity and complete re-expansion of lung. Neck drain and chest tube was extracted in postoperative second and fourth day respectively and patient was discharged at 8th day. Single port thoracoscopy is a safe choice for treatment of chylous leakages due to cervical ductus thoracicus injury with faster recovery.

The copper dependent-lysyl oxidases contribute to the pathogenesis of pulmonary emphysema in chronic obstructive pulmonary disease patients.

Abnormalities in the elastic fiber biology are seen in pulmonary emphysema (PE). The copper-dependent lysyl oxidases regulate the production and accumulation of elastic fibers in the connective tissue. This study focused on the relationship between lysyl oxidase (LOX), LOX-like protein 1 (LOXL1), and LOXL2 and PE pathogenesis. Lung samples with or without PE from patients with chronic obstructive lung disease (n=35) were used. Protein levels of elastin, LOX, LOXL1, LOXL2, hypoxia inducible factor 1-alpha (HIF-1α), copper metabolism domain containing-1 (COMMD1), and phosphatase and tensin homolog (PTEN) were assayed using microscopic and biochemical methods The emphysematous areas were characterized by enlargement of the alveoli, destruction of the alveolar structure, accumulation of macrophages in the alveolar lumens, and showed increased HIF-1α immunoreactivity. Additionally, the emphysematous areas had significantly lower elastin, LOX, LOXL1, LOXL2, HIF-1α, COMMD1, and PTEN protein levels than the non-emphysematous areas. We suppose that the reductions in the HIF-1α levels led to decreases in the protein levels of active LOX, LOXL1, and LOXL2. These decreases might cause abnormalities in the elastic fiber biology. HIF-1α activation induced by decreased COMMD1 and protease activation induced by decreased PTEN might contribute to the development of PE. Finally, methods aimed at increasing the protein levels of LOXs, COMMD1 and PTEN might be effective for treating PE.

Bronchus Associated Lymphoid Tissue Lymphoma Presenting with Immunodeficiency and Multiple Pulmonary Nodules.

Bronchus Associated Lymphoid Tissue Lymphoma (BALTOMA) is a rare subgroup of pulmonary non-Hodgkin's lymphomas (NHLs) comprising less than 1% of all cases. It constitutes 3.6% of all extranodal lymphomas and only 0.5-1% of primary pulmonary malignancies. They are usually low grade B-cell lymphomas and are considered to originate from the mucosa associated lymphoid tissue (MALT) of the bronchi. Here, we represent a rare case of BALTOMA presenting with immunodeficiency and multiple pulmonary nodules.

Evaluation of anterior mediastinal solid tumors by CT perfusion: a preliminary study.

PURPOSE: We aimed to assess the role of computed tomography (CT) perfusion in differentiation of thymoma from thymic hyperplasia, lymphoma, thymic carcinoma, and lung cancer invading anterior mediastinum. METHODS: In this study, 25 patients with an anterior mediastinal lesion underwent CT perfusion imaging from January 2015 to February 2016. Diagnoses included thymoma (n=7), thymic hyperplasia (n=8), lymphoma (n=4), thymic carcinoma (n=3), and invasive lung cancer (n=3). Lymphoma, thymic carcinoma, and lung cancer were grouped as malignant tumors for statistical analysis. Values for blood flow, blood volume, and permeability surface were measured in CT perfusion. RESULTS: Blood flow and blood volume values were higher in thymoma in comparison to thymic hyperplasia; however, the difference was not statistically significant. Blood volume values were significantly higher in thymoma (mean, 11.4 mL/100 mL; range, 5.2-20.2 mL/100 mL) compared with lymphoma (mean, 5.3 mL/100 mL; range, 2.5-7.2 mL/100 mL) (P = 0.023). Blood flow and blood volume values were significantly higher in thymoma compared with non-thymoma malignant tumors (P = 0.025). CONCLUSION: CT perfusion is helpful in differentiating thymoma from non-thymoma malignancies including lymphoma, thymic carcinoma, and invasive lung cancer involving the anterior mediastinum.

Single stage bilateral uniportal videothoracoscopic sympathicotomy for hyperhidrosis: can it be managed as an outpatient procedure?

INTRODUCTION: The videothoracoscopic approach is minimally invasive with benefits that include less postoperative pain and shorter hospital stay. It is also a safe procedure which can be performed on an outpatient basis. AIM: To determine whether videothoracoscopic sympathicotomy can be performed safely in most patients as an outpatient procedure. MATERIAL AND METHODS: Between July 2005 and October 2015, a total of 92 patients underwent bilateral and single port thoracoscopic sympathicotomy in our department on an outpatient basis. The level of sympathicotomy was T2 in 2 (2.2%) patients, T2 to T3 in 31 (33%) patients, T2 to T4 in 46 (50%) patients and T3 to T4 in 12 (13%) patients. Demographic data, length of postoperative stay, substitution index (SI), admission rate (AR) and readmission rate (RR), complications and patient satisfaction were reviewed retrospectively. RESULTS: Two (2.2%) patients suffered from chest pain, while 4 (4.3%) patients complained about pain at the port site. Mean discharge time after surgery was 5.1 h (range: 4-6 h), mean duration of hospital stay was 0.15 days (0-3 days) postoperatively and the mean operation time was 43.6 min (15-130 min). In 8 (8.6%) patients, pneumothorax was detected on postoperative chest X-ray, while 5 (5.4%) patients required chest tube drainage. Mild or moderate compensatory sweating developed in 32 (34.7%) patients. No recurrence was observed, and the satisfaction rate was 96.7%. Substitution index and admission rate were 91.3% and 11% respectively, while RR was 0%. CONCLUSIONS: Bilateral video-assisted thoracoscopic sympathicotomy can be performed safely in most patients as an outpatient procedure.

Minimally invasive repair of pectus excavatum (MIRPE) in adults: is it a proper choice?

INTRODUCTION: The Nuss procedure is suitable for prepubertal and early pubertal patients but can also be used in adult patients. AIM: To determine whether the minimally invasive technique (MIRPE) can also be performed successfully in adults. MATERIAL AND METHODS: Between July 2006 and January 2016, 836 patients (744 male, 92 female) underwent correction of pectus excavatum with the MIRPE technique at our institution. The mean age was 16.8 years (2-45 years). There were 236 adult patients (28.2%) (> 18 years) - 20 female, 216 male. The mean age among the adult patients was 23.2 years (18-45 years). The recorded data included length of hospital stay, postoperative complications, number of bars used, duration of the surgical procedure and signs of pneumothorax on the postoperative chest X-ray. RESULTS: The MIRPE was performed in 236 adult patients. The average operative time was 44.4 min (25-90 min). The median postoperative stay was 4.92 ±2.81 days (3-21 days) in adults and 4.64 ±1.58 (2-13) in younger patients. The difference was not statistically significant (p = 0.637). Two or more bars were used in 36 (15.8%) adult patients and in 44 (7.5%) younger patients. The difference was not statistically significant either (p = 0.068). Regarding the overall complications, complication rates among the adult patients and younger patients were 26.2% and 11.8% respectively. The difference was statistically significant (p = 0.007). CONCLUSIONS: MIRPE is a feasible procedure that produces good long-term results in the treatment of pectus excavatum in adults.

Pleural tuberculosis in a patient with untreated type 1 Gaucher disease.

Gaucher disease (GD) is an autosomal recessive glycolipid storage disorder, due to deficiency of the lysosomal enzyme glucocerebrosidase, leading to accumulation of the substrate glucocerebroside in the cells of the macrophage-monocyte system. Patients with GD have alteration in their immune system and impaired microbicidal capacity of mononuclear phagocytes. It has also been demonstrated that monocyte dysfunction may correlate with the plasma glucocerebrosidase concentrations. Tuberculosis (TB) is a major public health problem in developing countries. Pleural TB is one of the most common forms of extra-pulmonary TB. Since immune system can be impaired due to the deficiency of glucocerebrosidase in various ways, TB can be observed in patients with GD especially when left untreated. Cytopenia(s) is also general finding in untreated Gaucher patients, and they may be observed most frequently due to the infiltration of the bone marrow with Gaucher cells together with the additional factor of splenomegaly. We herein present a case of an adult patient with heterozygous untreated GD1, who developed pleural TB complicated by ipsilateral pulmonary fibrosis. Before his admission to our clinic, pleurectomy operation was performed and 4-drug combination anti-TB therapy was initiated including isoniazid, rifampicin, ethambutol and pyrazinamide. Fever complaint was disappeared with anti-TB treatment but he also had fatigue and pain. After initiation of enzyme replacement therapy in addition to anti-TB treatment, clinical and hematological improvement was observed. To our knowledge, this is the first reported case of GD1 with pleural TB.
