Impact of Previous Continuous Positive Airway Pressure Use on Noninvasive Ventilation Adherence and Quality in Obesity Hypoventilation Syndrome: A Pragmatic Single-Center Cross-Sectional Study in Martinique. Biomedicines 2023; 11:2753. [PMID: 37893126 PMCID: PMC10604741 DOI: 10.3390/biomedicines11102753] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Revised: 10/05/2023] [Accepted: 10/09/2023] [Indexed: 10/29/2023] Open
Abstract
There is a strong relationship between obstructive sleep apnea (OSA) and obesity hypoventilation syndrome (OHS). When OHS is combined with severe OSA, treatment consists of continuous positive airway pressure (CPAP), followed by noninvasive ventilation (NIV) in the case of CPAP failure. Currently, the impact of a previous use of CPAP on the quality of NIV is unknown. We conducted a cross-sectional study with OHS patients, to assess the quality of NIV according to previous CPAP use. We included 75 patients with OHS on NIV (65 women, 87%). Among these, 40 patients (53.3%) who had had prior CPAP (CPAP+ group) were compared to the remaining 35 patients (46.7%) (CPAP- group). Key characteristics were comparable between the CPAP+ and the CPAP- groups: age at diagnosis of OHS was 67 ± 3 vs. 66 ± 4 years (p = 0.8), age at inclusion was 73 ± 15 vs. 69 ± 15 years (p = 0.29), number of comorbidities was 3.7 ± 1.2 vs. 3.3 ± 1.5, the Charlson index was 5.1 ± 2 vs. 4.6 ± 1.8, and BMI was 41.6 ± 7.6 kg/m2 vs. 41.2 ± 8.2, respectively, all p > 0.05. Follow-up length was greater in CPAP+ vs. CPAP- patients (5.6 ± 4.2 vs. 2.9 ± 2.9 years, p = 0.001). The quality of NIV based on daily adherence, pressure support, apnea-hypopnea index (AHI) and leaks was similar in both groups. Reduced adherence (less than 4 h daily) was found in 10 CPAP+ patients (25%) versus 7 CPAP- patients (20%), p = 0.80. NIV efficacy was also similar. This study found no difference in the quality of NIV or in adherence between patients who had had prior CPAP and those who had not. Previous CPAP does not appear to improve the quality of NIV.

Phenotypic Profiles Among 72 Caucasian and Afro-Caribbean Patients with Antisynthetase Syndrome Involving Anti-PL7 or Anti-PL12 Autoantibodies. Eur J Intern Med 2023; 115:104-113. [PMID: 37330316 DOI: 10.1016/j.ejim.2023.06.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 06/12/2023] [Accepted: 06/13/2023] [Indexed: 06/19/2023]
Abstract
OBJECTIVES Antisynthetase syndrome (ASyS) is a rare autoimmune disease. We aimed to determine clinical, biological, radiological, and evolutive profiles of ASyS patients with anti-PL7 or anti-PL12 autoantibodies. METHODS We performed a retrospective study that included adults with overt positivity for anti-PL7/anti-PL12 autoantibodies and at least one Connors' criterion. RESULTS Among 72 patients, 69% were women, 29 had anti-PL7 and 43 anti-PL12 autoantibodies, median age was 60.3 years, and median follow-up period was 52.2 months. At diagnosis, 76% of patients had interstitial lung disease, 61% had arthritis, 39% myositis, 25% Raynaud's phenomenon, 18% mechanic's hands, and 17% had fever. The most frequent pattern on initial chest computed tomography was non-specific interstitial pneumonia and 67% had fibrosis at last follow-up. During follow-up, 12 patients had pericardial effusion (18%), 19 had pulmonary hypertension (29%), 9 (12.5%) had neoplasms, and 14 (19%) died. Sixty-seven patients (93%) received at least one steroid or immunosuppressive drug. Patients with anti-PL12 autoantibodies were younger (p=0.01) and more frequently exhibited anti-SSA autoantibodies (p=0.01); patients with anti-PL7 autoantibodies had more severe weakness and higher maximum creatine kinase levels (p=0.03 and 0.04, respectively). Initial severe dyspnoea was more common in patients from the West Indies (p=0.009), with lower predicted values of forced vital capacity, forced expiratory volume in 1s, and total lung capacity (p=0.01, p=0.02, p=0.01, respectively) contributing to a more severe 'respiratory' initial presentation. CONCLUSIONS The high mortality and significant numbers of cardiovascular events, neoplasms and lung fibrosis in anti-PL7/12 patients justify close monitoring and question addition of antifibrotic drugs.

Thoracic Endometriosis Syndrome (TES) in Martinique, a French West Indies Island. J Clin Med 2023; 12:5578. [PMID: 37685644 PMCID: PMC10488738 DOI: 10.3390/jcm12175578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 08/21/2023] [Accepted: 08/24/2023] [Indexed: 09/10/2023] Open
Abstract
INTRODUCTION Endometriosis is a female disease that affects 5-10% of women of childbearing age, with predominantly pelvic manifestations. It is currently declared as a public health priority in France. Thoracic endometriosis syndrome (TES) is the most common extra-pelvic manifestation. OBJECTIVE The objective of this study was to describe the epidemiological and clinical characteristics, and outcomes of patients with TES in Martinique. PATIENTS AND METHODS We performed a descriptive, retrospective study including all patients managed at the University Hospital of Martinique for TES between 1 January 2004 and 31 December 2020. RESULTS During the study period, we identified 479 cases of pneumothorax, of which 212 were women (44%). Sixty-three patients (30% of all female pneumothorax) were catamenial pneumothorax (CP) including 49 pneumothoraxes alone (78% of catamenial pneumothorax) and 14 hemopneumothorax (22% of catamenial pneumothorax). There were 71 cases of TES, including 49 pneumothoraxes (69%), 14 hemopneumothoraxes (20%) and 8 hemothorax (11%). The annual incidence of TES was 1.1 cases/100,000 inhabitants. The prevalence of TES was 1.2/1000 women aged from 15 to 45 years and the annual incidence of TES for this group was 6.9/100,000. The annual incidence of CP was 1 case/100,000 inhabitants. The average age at diagnosis was 36 ± 6 years. Eight patients (11%) had no prior diagnosis of pelvic endometriosis (PE). The mean age at pelvic endometriosis diagnosis was 29 ± 6 years. The mean time from symptom onset to diagnosis was 24 ± 50 weeks, and 53 ± 123 days from diagnosis to surgery. Thirty-two patients (47%) had prior abdominopelvic surgery. Seventeen patients (24%) presented other extra-pelvic localizations. When it came to management, 69/71 patients (97%) underwent surgery. Diaphragmatic nodules or perforations were found in 68/69 patients (98.5%). Histological confirmation was obtained in 55/65 patients who underwent resection (84.6%). Forty-four patients (62%) experienced recurrence. The mean time from the initial treatment to recurrence was 20 ± 33 months. The recurrence rate was 16/19 (84.2%) in patients who received medical therapy only, 11/17 (64.7%) in patients treated by surgery alone, and 17/31 (51.8%) in patients treated with surgery and medical therapy (p = 0.03). CONCLUSIONS We observed a very high incidence of TES in Martinique. The factors associated with this high incidence in this specific geographical area remain to be elucidated. The frequency of recurrence was lower in patients who received both hormone therapy and surgery.

Frequency and Distribution of Broncho-Alveolar Fungi in Lung Diseases in Martinique. J Clin Med 2023; 12:5480. [PMID: 37685550 PMCID: PMC10488106 DOI: 10.3390/jcm12175480] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 08/18/2023] [Accepted: 08/22/2023] [Indexed: 09/10/2023] Open
Abstract
The microbiota refers to all the microorganisms living in and on the human body; its fungal component is known as the mycobiota. The molecular component (mycobiome) has been linked to certain pulmonary diseases. Morphological fungal examination is still common practice and makes it possible to isolate fungi on direct examination or after sample culture. This study aimed to identify fungi via the genus colonising the respiratory tract in our environment and to evaluate the relationship between identified fungi and underlying diseases. We performed a retrospective study of patients who underwent bronchofiberoscopy and mycological analysis of fluid collected by broncho-alveolar lavage at our centre over a period of 5 years. During the study period, 1588 samples from 1547 patients were analysed (50.7% male, mean age 63.7 ± 14.8 years). Among the 1588 samples, 213 (13.4%) were positive on direct examination, and 1282 (80.8%) were positive after culture. The average number of species detected per sample was 1.4 ± 1.1. For patients with positive fungus, the median was two (ranging from one to seven). At least three fungal species were isolated in 14.4% of samples (17.9% of positive cultures), and at least two were isolated in 41.2% of samples (51.1% of positive cultures). Sterile mycelium was observed in 671 samples (42.28%), while Candida was identified in 607 samples (38.25%), and Geotrichum was identified in 271 samples (17.08%). Moulds were more frequently associated with bronchiectasis, while yeasts were associated with infectious pneumonia. Both moulds and yeasts were less frequent in diffuse interstitial lung disease, and yeast was less frequently present in chronic cough. Although overall, sterile mycelium and Candida were most frequently observed regardless of the underlying disease, there was nonetheless significant variability in the fungal genera between diseases. Fungal spores are highly prevalent in respiratory samples in Martinique. The species present in the samples varied according to the underlying respiratory disease.

Profiles of Elderly Patients with Obesity Hypoventilation Syndrome in Martinique: A Single-Center Study. J Pers Med 2023; 13:1089. [PMID: 37511702 PMCID: PMC10381235 DOI: 10.3390/jpm13071089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 06/28/2023] [Accepted: 06/28/2023] [Indexed: 07/30/2023] Open
Abstract
Obesity hypoventilation syndrome (OHS) is a form of chronic respiratory insufficiency related to obesity that affects young and old people. Age appears to be associated with poorer response to treatment by nighttime ventilation. This study aimed to describe the characteristics of elderly subjects (>65 years) with OHS compared to younger patients, with a view to adapting therapy in older individuals. We conducted a retrospective study comparing socio-demographic, clinical, functional characteristics as well as treatment and outcomes between young (<65 years) and older (65 years and older) individuals with OHS at the University Hospital of Martinique. We included 143 patients (114 women), of whom 82 were 65 years or older (57%). Charlson index was higher in the older group. Patients in ≥65 years group were less frequently obese, but more frequently had diabetes mellitus, cardiac arrythmia and arterial hypertension compared to younger patients. There was no difference in the circumstances of diagnosis or arterial blood gas at diagnosis. At follow up, partial pressure of carbon dioxide (pCO2) was higher in ≥65 years group. Despite comparable NIV settings, apart from lower expiratory positive airway pressure (EPAP) with higher apnea-hypopnea index (AHI), patients in the ≥65-year-old group remained more frequently hypercapnic. In conclusion, over half (57%) of patients with OHS in our cohort were aged over 65 years. Older patients developed OHS at lower BMI levels than their younger counterparts, and more frequently, had comorbidities such as diabetes, hypertension and cardiac arrhythmia. Increased Charlson index, lower BMI and female sex were independent factors associated with OHS in the elderly.

Factors Associated with the Efficiency of Home Non-Invasive Ventilation in Patients with Obesity-Hypoventilation Syndrome in Martinique. J Clin Med 2023; 12:jcm12103381. [PMID: 37240487 DOI: 10.3390/jcm12103381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 05/08/2023] [Accepted: 05/08/2023] [Indexed: 05/28/2023] Open
Abstract
Obesity-hypoventilation syndrome (OHS) is a respiratory complication of obesity characterized by chronic hypercapnic respiratory failure. It is often associated with several comorbidities and is treated by positive airway pressure (PAP) therapy. This study aimed to identify factors associated with persistent hypercapnia in patients receiving home non-invasive ventilation (NIV). We performed a retrospective study including patients with documented OHS. In total, 143 patients were included (79.7% women, age 67 ± 15.5 years, body mass index 41.6 ± 8.3 kg/m2). After 4.6 ± 4.0 years of follow-up, 72 patients (50.3%) remained hypercapnic. In bivariable analysis, clinical data showed no difference in follow-up duration, number of comorbidities, comorbidities, or circumstance of discovery. Patients with persistent hypercapnia on NIV were generally older, with lower BMI and more comorbidities. (5.5 ± 1.8 versus 4.4 ± 2.1, p = 0.001), female sex (87.5% versus 71.8%), was treated by NIV (100% versus 90.1%, p < 0.01), had lower FVC (56.7 ± 17.2 versus 63.6 ± 18% of theoretical value, p = 0.04), lower TLC (69.1 ± 15.3 versus 74.5 ± 14.6% of theoretical value, p = 0.07), lower RV (88.4 ± 27.1 versus 102.5 ± 29.4% of theoretical value, p = 0.02), higher pCO2 at diagnosis (59.7 ± 11.7 versus 54.6 ± 10.1 mmHg, p = 0.01) and lower pH (7.38 ± 0.03 versus 7.40 ± 0.04, p = 0.007), higher pressure support (12.6 ± 2.6 versus 11.5 ± 2.4 cmH2O, p = 0.04) and lower EPAP (8.2 ± 1.9 versus 9 ± 2.0 cmH2O, p = 0.06). There was no difference in non-intentional leaks and daily use between patients between both groups. By multivariable analysis, sex, BMI, pCO2 at diagnosis, and TLC were independent risk factors for persistent hypercapnia on home NIV. In individuals with OHS, persistent hypercapnia on home NIV therapy is frequent. Sex, BMI, pCO2 at diagnosis, and TLC were all associated with an increased risk of persistent hypercapnia in persons treated with home NIV.

Abstract
A worldwide pandemic of viral infection due to SARS-CoV-2 (and its resultant disease, COVID-19) has been ongoing since 2019. Martinique was affected by a major wave in summer 2021, with saturation of the health system forcing the implementation of home care management. We conducted a retrospective, observational study that included patients treated in the KOVIDHOM 972 program. We included adult patients with SARS-CoV2 hypoxemic pneumonia and requiring 4 L per minute or less of oxygen. In total, 418 were discharged to home with oxygen therapy after hospitalization for SARS-CoV-2 hypoxemic acute pneumonia, and 416 were analyzed. Half (50.2%) were women. Mean age was 58.8 ± 13.0 years. Time from onset of symptoms to hospitalization was 9.1 ± 3.5 days, and average length of stay was 10.5 ± 7.4 days. Maximum oxygen flow during hospitalization was 6.9 ± 4.5 L/min in patients who did not require intensive care. Average oxygen flow at discharge was 1.8 ± 07 L/min. At 30 days after discharge, the readmission rate was 0.5% (95% CI: 0-1.18), and the death rate was 0.5% (95% CI 0-1.18). Our study shows a very low rate of readmission or death in COVID-19 patients discharged to home with oxygen therapy. These results highlight the possibility of safe home care in carefully selected patients. Such programs could be useful in pandemic or wide-scale emergency situations.

Association between Previous CPAP and Comorbidities at Diagnosis of Obesity-Hypoventilation Syndrome Associated with Obstructive Sleep Apnea: A Comparative Retrospective Observational Study. J Clin Med 2023; 12:2448.

Abstract
Obesity-hypoventilation syndrome (OHS) is associated with many comorbidities. The aim of this study was to evaluate the association between previous continuous positive airway pressure (CPAP) and the prevalence of comorbidities in OHS associated with obstructive sleep apnea (OSA). We performed a retrospective, single-center study at the University Hospital of Martinique, the referral hospital for the island of Martinique. A total of 97 patients with OHS associated with severe OSA on non-invasive ventilation (NIV) were included; 54 patients (56%) had previous treatment of OSA with a positive airway pressure (PAP) device before shifting to NIV (PAP group) and 43 (44%) had no previous treatment of OSA with a PAP device before initiating NIV PAP (no PAP group). Sociodemographic characteristics were similar between groups; there were 40 women (74%) in the PAP group versus 34 (79%) in the no PAP group, mean age at OHS diagnosis was 66 ± 15 versus 67 ± 16 years, respectively, and the mean age at inclusion 72 ± 14 versus 71 ± 15 years, respectively. The average number of comorbidities was 4 ± 1 in the PAP group versus 4 ± 2 in the no PAP group; the mean Charlson index was 5 ± 2 in both groups. The mean BMI was 42 ± 8 kg/m2 in both groups. The mean follow-up duration was 5.8 ± 4.4 years in the PAP group versus 4.7 ± 3.5 years in the no PAP group. Chronic heart failure was less common in patients who had a previous PAP 30% versus 53% (p = 0.02). It is also noted that these patients were diagnosed less often in the context of acute respiratory failure in patients with previous PAP: 56% versus 93% (p < 0.0001). In contrast, asthma patients were more frequent in patients with previous treatment of OSA with a PAP device at the time of OHS diagnosis but not significantly: 37% versus 19% (p = 0.07). Early treatment of severe OSA with a PAP device prior to diagnosis of OHS seems to be associated with a reduced prevalence of cardiac diseases, notably chronic heart failure, in patients diagnosed with OHS associated with severe OSA.

Abstract
INTRODUCTION Histoplasmosis is a fungal disease caused by Histoplasma capsulatum. Histoplasma capsulatum var capsulatum is found in Martinique. Cluster cases following working in deserted house, have been described in Martinique. Cases of acute pulmonary histoplasmosis have been described in immunosuppressed individuals, or in case of substantial exposure to reservoirs of Histoplasma capsulatum; however, cases of acute histoplasmosis are rare in immunocompetent individuals. CASES SERIES We report a series of 4 cases of sporadic acute pulmonary histoplasmosis in immunocompetent subjects. Investigation revealed definite exposure in one patient and 3 cases with potential exposure. The diagnosis was microbiological and histological in 3 patients and histological in one patient. All subjects had positive serology to histoplasmosis. Pulmonary involvement was in the form of nodules and micronodules in 3 cases and ground glass lesions in one case. Patients were treated with itraconazole for 3 months and all had a favourable outcome. CONCLUSION We report a series of 4 cases of acute pulmonary histoplasmosis in immunocompetent individuals, occurring in a context where exposure was uncertain. This raises the problem of occult exposure in the Caribbean. Interventions to raise awareness and encourage caution are warranted targeting the population of the French West Indies and French Guiana.

Abstract
Aim: To analyze the impact of obesity on cardiopulmonary response to exercise in people with chronic post-coronavirus disease 2019 (COVID-19) syndrome. Patients & methods: Consecutive subjects with chronic post-COVID syndrome 6 months after nonsevere acute infection were included. All patients received a complete clinical evaluation, lung function tests and cardiopulmonary exercise testing. A total of 51 consecutive patients diagnosed with chronic post-COVID-19 were enrolled in this study. Results: More than half of patients with chronic post-COVID-19 had a significant alteration in aerobic exercise capacity (VO2peak) 6 months after hospital discharge. Obese long-COVID-19 patients also displayed a marked reduction of oxygen pulse (O2pulse). Conclusion: Obese patients were more prone to have pathological pulmonary limitation and pulmonary gas exchange impairment to exercise compared with nonobese COVID-19 patients. In this study, the cardiopulmonary response to exercise in people with chronic post-COVID-19 syndrome was analyzed. More than half of patients diagnosed with chronic post-COVID-19 had reduced exercise capacity 6 months after hospital discharge. In addition, patients with chronic post-COVID-19 syndrome who were overweight or obese displayed exaggerated hyperventilation along with an impairment of oxygenation at peak exercise.

Abstract
INTRODUCTION Lymphagioleiomyomatosis (LAM) and endometriosis are two diseases that occur in young women. The main thoracic complication of both diseases is pneumothorax. CASE REPORT We describe the case of a 45-year-old woman who presented with a right-sided pneumothorax. The clinical context and the perioperative findings were suggestive of thoracic endometriosis, while the histology of the pulmonary biopsy and the evolution of her case were in favour of LAM. This presentation indicates the coexistence of the two diseases, which has never previously been described in the literature. The case raises the question as to whether it should be policy to systematically undertake a pulmonary biopsy in cases of thoracic endometriosis. CONCLUSIONS LAM and endometriosis are both diseases under hormonal influence. To date, we do not know if there is any direct link between the two diseases or if the presentation that we describe here occurred by chance.

Abstract
Tracheal tumour is rare but can lead to upper airway obstruction and acute respiratory distress. Its management includes surgical resection, radiotherapy or interventional bronchoscopy. Ventilation or difficulties with tracheal intubation can occur during the peri-operative course resulting in serious adverse consequences. We report the case of an 83-year-old man with an obstructive tracheal chondrosarcoma resected by rigid bronchoscopy undergoing veno-venous extracorporeal membrane oxygenation. Such support should be considered when the patient's airway patency cannot be ensured by conventional methods.

Abstract
INTRODUCTION Cerebral air embolism is a rare complication of flexible fiberoptic bronchoscopy. It is a serious, life-threatening complication. The treatment consists of hyperbaric oxygen therapy. CASE REPORT We report the case of cerebral air embolism that occurred in an 80-year-old woman after a flexible bronchial fibroscopy with bronchial spur biopsies. The patient showed neurological signs after the procedure. The brain CT-scan found disseminated air emboli. The progress was fatal in the absence of specific treatment, taking account of the context, the patient's comorbidities and the wishes of the family. CONCLUSIONS Cerebral air embolism is a serious complication that can occur during a bronchial biopsy even though this complication is rare.

Abstract
INTRODUCTION Lung cancer is the leading cause of cancer deaths in the United States and worldwide. Biomarker testing is critical to personalized therapy in lung adenocarcinoma and has been extensively investigated in whites and Asians. However, little information addresses the underlying genetic changes among Caribbean and African Caribbean patients. In this study, we identified targetable biomarkers in Caribbean patients with lung adenocarcinoma. METHODS DNA extracted from lung adenocarcinoma specimens collected from 157 patients in whom primary lung adenocarcinoma was diagnosed from 2013 to 2015 in the University Hospital of Martinique was tested for mutation of the epidermal growth factor receptor gene (EGFR), Kirsten rat sarcoma viral oncogene homolog gene (KRAS), B-Raf proto-oncogene, serine/threonine kinase gene (BRAF), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha gene (PIK3CA), ROS proto-oncogene 1, receptor tyrosine kinase gene (ROS), and MMNG HOS Transforming gene (MET). Clinical characteristics of our patients have been retrospectively gathered and correlated with mutational status. RESULTS Mutations in EGFR were identified in 57 cases (36%). Women accounted for 68% of patients with mutations versus 38% of those without mutations (p < 0.001). Eighteen percent of patients with mutations were smokers versus 62% of patients without mutations (p < 0.001). Sex, smoking habit, and age were significantly associated with differences in mutational status in univariate analysis, and the difference remained statistically significant in multivariate analysis (p = 0.0411, p = 0.001, and p = 0.0483, respectively). After the analysis was restricted to patients born in the French West Indies, the mutation rates reached 41%. CONCLUSION Patients in Martinique, and specifically those of African descent, show very high levels of EGFR mutation as opposed to what can be found in mainland France or in African Americans. These findings may be ascribed to low tobacco consumption as well as to genetic factors. Systematic screening in patients of African Caribbean origin should be prescribed.
