Case Report: Allergic Bronchopulmonary Aspergillosis Revealing Asthma

Allergic bronchopulmonary aspergillosis (ABPA) is an immunological pulmonary disorder caused by hypersensitivity to Aspergillus which colonizes the airways of patients with asthma and cystic fibrosis. Its diagnosis could be difficult in some cases due to atypical presentations especially when there is no medical history of asthma. Treatment of ABPA is frequently associated to side effects but cumulated drug toxicity due to different molecules is rarely reported. An accurate choice among the different available molecules and effective on ABPA is crucial. We report a case of ABPA in a woman without a known history of asthma. She presented an acute bronchitis with wheezing dyspnea leading to an acute respiratory failure. She was hospitalized in the intensive care unit. The bronchoscopy revealed a complete obstruction of the left primary bronchus by a sticky greenish material. The culture of this material isolated Aspergillus fumigatus and that of bronchial aspiration fluid isolated Pseudomonas aeruginosa. The diagnosis of ABPA was based on elevated eosinophil count, the presence of specific IgE and IgG against Aspergillus fumigatus and left segmental collapse on chest computed tomography. The patient received an inhaled treatment for her asthma and a high dose of oral corticosteroids for ABPA. Her symptoms improved but during the decrease of corticosteroids, the patient presented a relapse. She received itraconazole in addition to corticosteroids. Four months later, she presented a drug-induced hepatitis due to itraconazole which was immediately stopped. During the monitoring of her asthma which was partially controlled, the patient presented an aseptic osteonecrosis of both femoral heads that required surgery. Nine months after itraconazole discontinuation, she presented a second relapse of her ABPA. She received voriconazole for nine months associated with a low dose of systemic corticosteroid therapy with an improvement of her symptoms. After discontinuation of antifungal treatment, there was no relapse for one year follow-up

A rare coexistence of sarcoidosis with overlap syndrome and sarcoidosis with primary biliary cholangitis and Sjogren's syndrome: Two distinct case reports

Sarcoidosis and the overlap syndrome of autoimmune hepatitis and primary biliary cholangitis (PBC) share common clinical, biological, and histological features. The simultaneous occurrence of these diseases have been reported in few cases and suggests that a common pathway which may contribute to granuloma formation in both conditions.We report the cases of two female patients having an association of sarcoidosis and inflammatory liver diseases.The first case is of a 61-year-old woman had been monitored for an overlap syndrome of PBC and autoimmune hepatitis (AIH). Therefore, treatment with azathiprine has been initiated associated with ursodeoxycholic acid (UDCA). Azathioprine had to be discontinued due to digestive intolerance, specifically chronic diarrhea and abdominal pain. The patient remained clinically stable on UDCA and her liver function tests were stable for years, until she developed symptoms of progressive dyspnea without any other associated signs. Chest computed tomography (CT) revealed mediastinal enlargement, bilateral pulmonary nodules, and symmetrical adenomegalies in the mediastinum. The bronchoalveolar lavage (BAL) revealed increased cellularity, with a notable elevation in lymphocyte count (48 %) and a CD4/CD8 ratio of 4. The patient underwent mediastinoscopy; a biopsy of the right laterotracheal (4R) adenomegaly was performed. Histological examination of the lymph node showed epithelioid and giant-cell tuberculoid lymphadenitis without necrosis, compatible with sarcoidosis. Ophthalmological and cardiac assessments were normal. Plethysmography test was normal and there was no need for corticosteroid treatment; a surveillance was planned. Treatment with UDCA was pursued. The second case is of a 50-year-old woman with no medical history presented symptoms including dry eyes and mouth, inflammatory-type polyarthralgia affecting knees and wrists, bilateral Raynaud's phenomenon, right hypochondrium pain, and worsening dyspnea over six months. Liver analysis showed elevation of alkaline phosphatase (ALP) to three times upper limit of normal (ULN) and gamma-glutamyltransferase (GGT) to 5 times ULN. This cholestasis was associated with an increase in transaminase activity to 5 times ULN for over six months. Immunological tests revealed positive anti-nuclear antibodies (ANA), anti-Ro52, anti-M23E, and anti-centromere antibodies. Chest-CT showed multiple bilateral bronchiolar parenchymal micronodules mostly in the upper and posterior regions without any mediastinal adenomegaly. Bronchial endoscopy was normal, and biopsies indicated chronic inflammation. The BAL revealed increased cellularity, characterized by a high lymphocyte count (51.7 %) and a CD4/CD8 ratio of 2.8. Biopsy of minor salivary gland revealed grade 4 lymphocytic sialadenitis. Skin biopsy revealed an epithelioid granuloma without caseous necrosis. Liver biopsy performed in the presence of cytolysis and moderate hepatic insufficiency, revealed granulomatous hepatitis and cholangitis lesions along with septal fibrosis suggestive of PBC. The diagnosis of cutaneous and pulmonary sarcoidosis with PBC and Sjögren's syndrome was retained. The spirometry and diffusing capacity for carbon monoxide value were normal. Treatment involved UDCA, corticosteroids, and azathioprine, leading to clinical and biological improvement.Sarcoidosis shares some clinical manifestations with autoimmune liver diseases, primarily PBC. A hepatic granuloma with a different appearance and location can guide the diagnosis. Early diagnosis and appropriate management can avoid serious complications and improve prognosis
