Pulmonary MALT lymphoma associated with interstitial pulmonary disease

Interstitial lung disease (ILD) and low-grade Mucosa-associated B-cell lymphoma (MALT lymphoma) are two different disorders of the respiratory system. In some cases, pulmonary MALT lymphoma is seen presenting with interstitial lung disease. We report a case of 42-year-old man presenting with a pulmonary MALT lymphoma associated with interstitial lung disease.

Diabète de primodécouverte chez les patients atteints de covid-19 dans l’unité d’isolement de l’hôpital de Mahdia

Introduction

La relation entre diabète et infection Covid 19 avait suscité un intérêt particulier. L’infection ainsi que son traitement par corticoïdes pourrait décompenser, révéler ou induire un diabète sucré.

Résultats

Il s’agit d’une étude rétrospective portant sur 200 patients hospitalisés pour pneumopathie due au SARS-cov2 entre décembre 2020 et avril 2021. Presque la moitié avait un diabète connu (45 %). L’âge moyen était plus avancé chez cette population (66 ans pour les sujets ayant un diabète vs 63,9 ans). La moyenne des glycémies à l’admission des personnes non connues avoir un diabète était à 13. 94 mmol/l et celle de l’HBA1C à 8. 58 %. 86 % d’entre eux avaient des comorbidités (HTA dans 50 % des cas). Le tableau clinique chez ces patients était marqué par la dyspnée (91 %), la fièvre (72,3 %), la toux sèche (36,4 %) et l’asthénie (27,3 %). Une hospitalisation initiale en réanimation avait intéressé 13. 6 % de ces patients. L’atteinte scanographique était sévère (> 50 % du parenchyme) dans 75 % des cas. Leur PaO2 moyenne initiale était de 70,59 mmhg avec un besoin en oxygène de 5,12 l/min. La corticothérapie était prescrite chez 86,4 % de ces patients. L’évolution était favorable dans 90 % des cas. À la sortie, 50 % des patients qui n’avaient pas de diabète dans leurs antécédents étaient traités par insuline.

Conclusion

Malgré la sévérité de l’atteinte pulmonaire, les comorbidités et la prévalence de diabète associé à l’infection Covid 19 chez nos patients, le pronostic était globalement favorable. Il sera important de rechercher la proportion et le type de diabètes démasqués ou induits par l’infection.

Predictive echocardiographic factors of severe obstructive sleep apnea

Introduction

obstructive sleep apnea (OSA) is a common chronic pulmonary disease, characterized by repetitive collapse of the upper respiratory airways, leading to oxygen desaturation. This condition is recognized to be associated with cardiovascular disease. Several studies have shown the effects of OSA on both geometry and cardiac function, with conflicting results. We aimed to investigate the relationship between echocardiographic abnormalities and the severity of OSA.

Methods

this is a cross-sectional single center study including patients, without any cardiovascular or pulmonary comorbidities, with polygraphy proven OSA. All participants underwent a detailed transthoracic echocardiography (TTE).

Results

a total of 93 patients were included in the study, with 62.2% (n=56) females. According to the apnea hypopnea index (AHI), patients were divided into two groups: mild to moderate OSA (5≤ AHI< 30/H) and severe OSA (AHI≥ 30/H). There were no differences in baseline characteristics between the two groups. The assessment of echocardiographic parameters demonstrated that severe OSA have a higher left ventricular end-systolic (LVES) (47.6±7.2 VS 46.2±4.7), left ventricular end-diastolic (LVED) (31.3±6.2 VS 28.9±4.5) diameters and interventricular septum (IVS) thickness (12.7±2.4 VS11.7±2.5) diameters rather than mild to moderate OSA without a significant difference between the two groups. Furthermore, severe OSA patients had lower mean value of left ventricular ejection fraction (LVEF) and fractional shortening (FS) equal to 62.1±9.7 and 32.5±6.3 respectively. The difference between the two groups was not statistically significant. However, a significant association was shown between severity of OSA and left ventricular (LV) diastolic dysfunction, right ventricular internal diameter (RVID) and systolic pulmonary artery pressure (sPAP), with p=0.05, p=0.05 and p= 0.03 respectively. The RVID was also independently associated to the severity of the OSA (aOR 1.33, 95%CI: 0.99-1.79; p=0.05).

Conclusion

using bidimensional echocardiography showed a relationship between severe OSA and right ventricular parameters (diastolic dysfunction and RVID) and sPAP.

Assessment of right ventricular remodeling and dysfunction in obstructive sleep apnea syndrome: a prospective monocentric study

BACKGROUND

Obstructive sleep apnea (OSA) is a common sleep-related disorder that has been implicated in many serious cardiovascular diseases including cardiac remodeling and dysfunction. Since most investigations have focused on the left heart, little is known on right ventricular (RV) involvement in OSA. The role of the RV in the management of cardiovascular outcomes has become increasingly recognized. Early detection of subtle signs of RV dysfunction and remodeling in patients with OSA is crucial for optimal medical care.

PURPOSE

We aimed to investigate the effect of OSA and its severity on the RV structure and function using conventional echocardiography.

METHODS

We conducted a cross-sectional analytical study including patients with OSA who did not have heart failure or chronic pulmonary disease comparing them to controls without OSA. All patients underwent respiratory polygraphy at the Pneumology Department and standard echocardiography performed by the same blinded cardiologist at the Cardiology Department of Taher Sfar University Hospital.

RESULTS

A total of 139 patients with OSA and 45 controls were enrolled in the study. Amonth the patients, there were 32% (n = 44) with mild, 20% (n = 28) with moderate, and 48% (n = 67) with severe OSA. Sixty-three percent of the study population were women. The mean age was 54.1 ± 11.0 years. Early RV dilatation was present in the mild disease stage (RVID = 42.0 ± 7.7 mm vs. 32.4 ± 5.5 mm in controls; p < 0.0001) without obvious RVH. The systolic pulmonary artery pressure was significantly higher in patients with OSA (31.2 ± 8.2 vs. 20.9 ± 9.8; p < 0.0001). Tricuspid annular plane systolic excursion was borderline normal and significantly lower in patients with OSA (17.7 ± 4.7 vs. 26.0 ± 5.7, p < 0.0001). In multivariate analysis, an OSA was independently associated with RV remodeling (OR: 0.257, 95% CI [0.114-0.582], p = 0.001) but not with RV dysfunction.

CONCLUSION

OSA was independently associated with structural alterations of RV early in the disease course, suggesting that the reversibility of these deleterious effects requires earlier detection and initiation of treatment.

[Prognostic factors in idiopathic pulmonary fibrosis in a tunisian cohort]

We present data on prognostic factors in a Tunisian cohort of people with Idiopathic pulmonary fibrosis.

INTRODUCTION

Idiopathic pulmonary fibrosis (IPF) has a poor prognosis, with a median survival in patients with the condition of only 3 to 5 years. Previous studies have identified a number of prognostic factors in this chronic pulmonary disease.

METHODS

We conducted a retrospective study, including patients with idiopathic pulmonary fibrosis (IPF) who were diagnosed at the Pneumology Department of the University Hospital Fattouma-Bourguiba, Monastir, between 1991 and 2014. The aim of this study was to compare clinical, radiological, pulmonary functional predictors of survival in IPF in a Tunisian cohort with those of previous studies.

RESULTS

This study included 126 patients. Their mean age was 66 years, with a male predominance (68.3%). Respiratory function tests revealed a restrictive ventilatory deficit in 72.6% of cases. The median survival of our study population was 22.5 months [6.7-49.5]. In univariate analysis, factors associated with a poor prognosis were: lower baseline values of TLC, FCV and DLco, level of dyspnea assessed by mMRC scale, hypoxemia at diagnosis, the degree of desaturation during exercise, a higher annual decline of FVC and DLco, acute respiratory distress and also the GAP score. In multivariate analysis, independent prognostic factors were: baseline DLco, level of dyspnea, desaturation at exertion and the annual decline of the DLco.

CONCLUSION

Lower baseline DLco, the level of dyspnea, desaturation on exercise, and annual decline in DLco are all associated with a poor prognosis in IPF.

Isolated left pulmonary artery hypoplasia

Pulmonary artery hypoplasia is a rare malformation of childhood that is usually associated with cardiac abnormalities. In the absence of these cardiac malformations it is discovered later when respiratory signs appear. It was a 56-year-old patient who had been referred for dyspnea with cough. The physical examination was normal. Chest X-ray, thoracic computed tomography (CT) scan and echocardiography suggested the diagnosis of hypoplasia of the left pulmonary artery without associated cardiac malformations. The early diagnosis of hypoplasia of the pulmonary artery allows the close follow-up of these patient and the planning of an adequate management.

[Asthma control and quality of life]

INTRODUCTION

The assessment of asthma control is based on objective measures: clinical, pharmacological and spirometry. However subjective component may be also necessary for assessing asthma control.

OBJECTIVES

To study the feasibility and clinical value of the assessment of the quality of life of patients with asthma by the SF-36 (Medical Outcomes Study Short Form) and the possible existence of a correlation between controlled asthma and a better quality of life.

PATIENTS AND METHODS

A prospective study that included 167 patients with asthma in a stable condition. Control of asthma and SF-36 were established three months after the inclusion of patients.

RESULTS

The SF-36 was lower in the uncontrolled group in all areas of the physical component and the difference was significant in the "limitation related to physical activity" and "perceived health". In the mental component, the score was lower in "mental health" and the "limitation due to mental state" in the group with uncontrolled asthma and the difference was significant only in the limitation due to mental state (P=0.043).

CONCLUSION

The quality of life of asthmatic patients is correlated to the control of this disease.

[Obesity and the severity of asthma crisis]

INTRODUCTION

Obesity is associated with inflammatory processes, which could influence the airway inflammation that is found in patients with asthma. Obesity may thus have a role in the development of asthma. However, the role of obesity in the severity of acute asthma has not been well described.

PATIENTS AND METHODS

We performed a retrospective study, which included 77 patients hospitalized for acute asthma. Two groups of patients were formed according to their body mass index (BMI): group 1 consisting of 59 patients with a BMI inferior to 30 kg/m(2) and group 2 consisting of 18 patients with a BMI superior or equal to 30 kg/m(2). These two groups were compared according to demographic factors, clinical features and the spirometric severity of asthma.

RESULTS

The mean age was 43 ± 17.4 years with a sex-ratio 0.57 (28 men/49 women). Thirty-one percent of these patients had a severe asthma attack requiring hospitalization in intensive care in four patients with the use of mechanical ventilation in two patients. The comparison between obese and non-obese patients did not show a significant difference in the severity of asthma.

CONCLUSION

Although a contribution of obesity to the manifestation and severity of asthma is commonly recognized, the present data to not confirm the impact of obesity on the severity of acute attacks.

[Right upper lobe pulmonary agenesis]

INTRODUCTION

Pulmonary agenesis is a rare congenital anomaly. Other cardiovascular, gastrointestinal, musculoskeletal, and urogenital system anomalies can be observed in association with it.

CASE REPORT

A 24-year-old female patient presented to our clinic with a history of cough and chest pain with an abnormal chest X-ray. Physical examination was normal. Chest X-ray, CT-Scan and endoscopy led to the diagnosis of right upper lobe pulmonary agenesis.

CONCLUSION

The diagnosis of pulmonary malformations like agenesis or hypoplasia can be delayed and may not occur until adulthood. Once the diagnosis has been established medical follow up is mandatory.

[Unusual alveolar proteinosis]

Pulmonary alveolar proteinosis (PAP), a rare infiltrative disease of unknown aetiology, is characterized by an accumulation of abnormal lung surfactant in the alveoli. The diagnosis is based on the results of the bronchoalveolar lavage (BAL) and sometimes on the lung biopsy. The authors report the case of a 49-year-old woman who was hospitalized for chronic expectoration of the membranes. The chest X-ray revealed alveolar opacities in the lowest part of the right lung. The chest CT scan detected alveolar ground glass opacities with interlobular thickening involving the middle lobe. The BAL was opaque with periodic acid-Schiff stain-positive acellular material. The anatomopathology analysis of the membranes concludes as to the presence of granular eosinophilic material and the absence of neoplasic cells or hydatidous membranes. The diagnosis of PAP was established. Since functional deterioration was not detected, therapy was based on physiotherapy alone. The evolution was favourable, with the disappearance of the symptomatology and the normalisation of the chest X-ray. This observation shows an unusual presentation of PAP based on membrane expectoration and unusual localized lesions.

[Rare primary chest wall sarcoma: the synovialosarcoma]

INTRODUCTION

Malignant primary tumours occurring in the thorax encompass a large group of tumours which may arise from the lung, mediastinal structures, the pleura or the chest wall.

OBSERVATION

We report the case of a 37 year old patient, who presented with left sided chest pain. On clinical examination a right sided chest wall mass was identified. Chest X Ray showed a left sided upper mediastinal opacity, associated with a left sided pleural opacity. Thoracic CT scan revealed a large mass arising from the chest wall and infiltrating the mediastinum associated with a second chest wall mass at the level of the 8(th) and 9(th) right ribs. The biopsy of the chest wall mass revealed it to be a parietal synovialosarcoma. The patient responded to chemotherapy based on ifosfamid and doxorubicin as well as mediastino-pulmonary radiotherapy. There was an improvement in the patient's clinical and radiological state but the patient died by pulmonary embolism after the 3(rd) cause of treatment.

CONCLUSION

Chest wall synovialosarcoma has a poor prognosis, however, its chemosensitivity means that treatment may initially be effective.

[Allergic bronchopulmonary aspergillosis. A review of 3 cases]

BACKGROUND

Allergic bronchopulmonary aspergillosis (ABPA) is a rare affection, initially described in 1952. Its pathophysiology incriminate several mechanisms in relation with the organism of the patient and the bronchial colonisation by the fongic agent.

AIM

To report three cases of ABPA.

CASES REPORT

Three patients had been treated for ABPA in Ibn Nafiss department in Abderrahmen Mami hospital in Ariana. ABPA had been discovered in the three cases by a cortico dependant asthma, refractory for different therapeutics. Positive diagnosis reposed in the 3 patients at 6 major and one minor criterion. Treatment was essentially based in corticotherapy.

CONCLUSION

Positive diagnosis of ABPA is actually well established, however, its treatment, although based on corticotherapy, remind not clearly codified. Association of antifongic treatment may improve the prognosis.

[Pulmonary atinomycosis: a great clinical polymorphism]

BACKGROUND

Pulmonary actinomycosis is a rare bacteriological disease, caracterized by local suppuration and an extensive fibroinflammatory process, with a possible pseudotumoral outcome.

AIM

To report a new observation of a pulmonary actinomycosis.

CASE REPORT

A 52-year-old patient, smoker, admitted in our department for infectious pneumopathy complicated by purulent pleurisy. Clinical and radiological findings were not contributive.Fiberoptic had evocate the diagnosis of bronchopulmonary cancer. Evolution had been marqued by abondant hemoptysia indicating right low lobectomie. The diagnosis of actinomycosis was obtained by the pathology of the surgical resection.

CONCLUSION

Diagnosis of pulmonary actinomycosis can be difficult because it can mimic the presentation of lung carcinoma.If the diagnosis is no late established, and if the patient is correctely treated medically, the prognosis still excellent.

[Thoracic manifestations of systemic lupus erythematosus]

BACKGROUND

Systemic lupus erythematosus (SLE) is an autoimmune disease. The respiratory system is more commonly involved in SLE than in any other collagen vascular disease.

AIM

To study the pleuropulmonary manifestations of SLE.

METHODS

Retrospective study including 10 patients hospitalized between January 2000 and December 2008 for pleuro-pulmonary manifestation revealing or complicating the SLE.

RESULTS

Nine women and only one man aged between 21 and 67 years-old were included in this study. Two patients had already SLE and for the other patients the pleuro-pulmonary manifestations were revealing the SLE. Pleural effusion was the most common manifestation witch represents 50% of the patients. For the other patients we find one case of interstitial pneumonia, one case of pulmonary embolism, on case of pneumonia, on case of pulmonary haemorrhage and on case of pulmonary hypertension. All these patients were treated by corticoids and only one patient takes high doses of corticoids for managing a massive pulmonary haemorrhage. The evolution was favourable for 9 patients, one patient dead because of massive pulmonary haemorrhage complicated with acute respiratory failure.

CONCLUSION

Pleuro-pulmonary involvement in SLE is common and may be life threatening, in which case prompt and aggressive treatment is mandatory.

[Neuropsychiatric side effects of antituberculosis agents]

Accurency of neurological or psychiatric complications secondary to the administration of antituberculosis may be at the origin of diagnosis and therapeutic problems. This work aims at studying the frequency of these manifestations, their clinical presentations and their therapeutic approach.

PATIENTS AND METHODS

This retrospective study was carried on from January 1990 to June 2008 at Ibn Nafis Pulmonary Department of Abderrahmen Mami Hospital in Ariana. It dealt with 18 in-patients with a neurologic or a psychiatric complication due to antituberculous drugs. Peripheral neuropathy was noted in 6 patients (33%). One of them had a history of chronic alcoolism, another one had a history of diabetes mellitus and 2 other patients were more than 72 years old. We had definitively stopped isoniazide in 2 cases and decreased the dosage in 4 other patients. However, all patients received B6 vitamin. Convulsions occured in 2 women without any history of epileptic status. Anticonvulsivant treatment was prescribed and isoniazid definitively stopped. Hallucinosis was noted in 4 patients, with one having a history of chronic alcoolism. Isoniazide was stopped in all cases. Agressivity, insomnia and memory problems were noted in 6 patients. Isoniazid was interrupted in only one woman who had history of depression. In 5 other patients, anxiolytics were prescribed. Isoniazide was incrimined in all cases and evolution was favorable for the 18 patients. A close monitoring of patients on antituberculous treatment is required to detect the onset of any neuropsychiatric complications incriminating usually isoniazid. Definitive interruption or decrease of the dose of isoniazid depending of the acetylation test were necessary.

[Neoplasic vena cava syndrome]

BACKGROUND

Vena cava superior syndrome results of an obstruction of superior vein cava(SVC)and/or brachiocaphalic venous troncs by extrinsic compression and/or by tumoral or cruoric thrombosis. The bronchopulmonary cancer represents the most frequent aetiology.

AIM

The aim of this study is to establish clinical, radiological, evolutive profiles and modalities of treatment of neoplasic vena cava superior syndrome independently of its histological type.

METHODS

It is a retrospective study about 20 patients presenting vena cava superior syndrome complicating primary bronchopulmonary cancer, hospitalised between January 2000 and December 2007 in Ibn Nafiss department in Abderrahmen Mami hospital.

RESULTS

All patients were males with an average of 57,8 years. Vena cava superior syndrome had revealed cancer in 60% of cases. It was metachrone in 40% of the patients. The most frequent histological type was small cell lung cancer. Treatment was proceeded in 2 steps, symptomatic and etiologic for the bronchopulmonary cancer.

CONCLUSION

The bronchopulmonary cancer is the most frequent aetiology of vena cava superior syndrome. Its treatment is actually well codified.

[Tuberculosis in patients with asthma]

INTRODUCTION

The association of asthma and tuberculosis is rare but may raise particular issues around patient management. The aim of this study was to evaluate the clinical, therapeutic and progress of this association.

PATIENTS AND METHODS

We describe a retrospective study, which included seven asthmatic patients hospitalized for pulmonary tuberculosis during the period between June 2001 and June 2006.

RESULTS

Five men and two women were included. Mean age was 37 years. Two patients had mild asthma, four had moderate asthma and one had severe and corticosteroid-dependant asthma. Only four patients had controlled asthma when tuberculosis diagnosis was established. Asthma treatment was based on inhaled corticoids and long-acting beta-2-agonists. During antituberculosis treatment two patients developed near fatal asthma. Long-term stable asthma control was achieved over a time course of 3 to 8 years.

CONCLUSION

The association of asthma and tuberculosis can lead to potential therapeutic difficulties because of pharmacologic interactions between antituberculosis therapies and treatments for asthma treatment. In addition asthma following treatment for tuberculosis appears to be well controlled.

[Effect of tobacco smoking on pulmonary tuberculosis]

Tobacco increases the risk of pulmonary infection, especially tuberculosis. We try by this study to analyse this action. It's a comparative study between two groups of patients hospitalized in our department between January 2006 and June 2008. The first group was made of 30 smokers patients hospitalized because of confirmed pulmonary tuberculosis. The second group consists of 30 non smokers patients and also hospitalized because of confirmed pulmonary tuberculosis. Delay of diagnosis was longer in the group of smokers (3, 1 +/- 3 months versus 2 +/- 1 month with p = 0.039). The most frequent symptoms in both groups were cough and loss of weight. The biological investigations showed a high level of white blood cells with predominance of neutrophil cells especially in smokers (p = 0.024). Chest X ray showed essentially nodules in both groups. These nodules were bilateral in smokers (P = 0.045). Evolution after antituberculosis treatment was favourable for all patients. A delay of recovery (time between symptoms and recovery) was longer in smokers than in non smoker patients (p = 0.043). Pulmonary Sequels such as dyspnoea (p = 0.016) and fibrosis (p = 0.041) were most frequent in smokers. No patients had tuberculosis relapse. Tobacco may delay the recovery of pulmonary tuberculosis and may induce pulmonary sequels in spite of correctly antituberculosis treatment.

[Pleural empyema revealing osteopoikilosis]

INTRODUCTION

Osteopoikilosis is a rare, inherited and usually asymptomatic sclerosing bone dysplasia of unknown etiology which predominantly involves the appendicular and rarely the axial skeleton.

CASE REPORT

We report the case of a 24 year old man who was hospitalized for pleural empyema and treated with antibiotics for six weeks in addition to pleural evacuation and physiotherapy. The diagnosis of osteopoikilosis associated with the pleural empyema was made on the radiological findings. In fact the chest X-Ray showed spherical areas of increased bone density in both humeral epiphyses. In order to explore these bone abnormalities further investigations were performed, including red and white blood cell counts, sedimentation rate and protein electrophoresis. There were no biological abnormalities. Radiography of the whole skeleton showed disseminated sclerotic lesions in the pelvis and the metacarpal and carpal bones of both hands. A neoplastic aetiology was excluded. In the light of these investigations, the diagnosis of osteopoikilosis was established.

CONCLUSION

Widespread osteopoikilosis can be revealed on chest radiography.

[Echinococcosis of the rib with epidural extension]

Osseous hydatidosis, especially when located in the rib, is a very rare disease. Less than 50 cases of costal echinococcosis have been reported in the literature to date. The authors report a case of echinococcosis of the rib with epidural extension in a 76-year-old patient presenting paraparesis. In addition, the patient presented a large posterior and thoracic soft tissue mass measuring about 30 centimetres in diameter. A chest x-ray, a CT thoracic scan and an MRI of the dorsal spine were performed. The imaging suggested echinococcosis of the rib with epidural extension. The cyst was completely resected. Histopathology of the resected specimen confirmed the diagnosis of echinococcosis. The patient died due to postoperative complications. Accurate presurgical diagnosis allows for appropriate management and helps eradicate the disease. This also prevents the dissemination of parasites and further complications.

[Broncholithiasis]

INTRODUCTION

Broncholithiasis is defined as the presence of calcified material in the bronchial lumen. The aim of our work was to study the clinical, radiological and therapeutic aspects of broncholithiasis.

OBSERVATIONS

We report the histories of 6 patients identified over 14 years (1990-2004). They included 4 men and 2 women with an average age of 50 years. A past history of pulmonary tuberculosis was found in 2 cases. The presenting symptom was haemoptysis in 4 patients. Fibreoptic bronchoscopy was performed in all patients and broncholiths were found in two. Thoracic CT scan was performed in 5 patients and in 3 showed hilar and parenchymal calcification, suggesting the diagnosis of broncholithiasis. The diagnosis was confirmed in 2 patients by bronchoscopy, in 2 others by surgical biopsy and in the remaining 2 by the CT appearances. Three patients were operated on: 2 for diagnosis and the third for haemostasis. Pulmonary tuberculosis was discovered in 2 patients, one by culture and the other by surgical biopsy. The outcome was satisfactory in all cases.

CONCLUSIONS

Broncholithiasis presents a problem of differential diagnosis from other pulmonary pathologies on account of misleading clinical, endoscopic and radiological features.
