Bronchial thermoplasty (BT) is a bronchoscopic treatment for severe asthma. A 35-year-old woman with uncontrolled severe asthma despite maximal pharmacological treatment underwent BT and started coughing after the first procedure. One month later, during the second BT procedure, there were white ulcerous lesions on the right B9 bronchus. Read More

Chronic granulomatous disease is an uncommon primary immunodeficiency due to a defect of the killing activity of phagocytes, caused by mutations in any of the genes encoding subunits of the superoxide-generating phagocyte NADPH oxidase system. The incidence is 1 in 250 000 live births. It can occur from infancy to adulthood, usually in children under 2 years. Read More

Objectives: Nocardiosis is an opportunistic infection that can present as cutaneous, pulmonary and/or disseminated disease depending on the host immunity. Treatment choices include trimethoprim/sulfamethoxazole (co-trimoxazole; SXT) and imipenem along with some other antibiotics. The Clinical and Laboratory Standards Institute (CLSI) recommends the broth microdilution (BMD) method to determine antimicrobial susceptibility, however there is a lack of susceptibility data using this method in Pakistan.

Cutaneous nocardiosis is an infrequent infection which has been increasingly reported in immunocompromised patients. Although trimethoprim-sulfamethoxazole is considered to be the agent of choice for treatment of nocardiosis, newer antimicrobials such as tigecycline have been proven to be effective in vitro, as well. We report the first case of primary cutaneous nocardiosis in a renal transplant recipient having corresponded well to treatment with tigecycline. Read More

Nocardiosis is a rare localized or systemic suppurative disease caused by the actinomycete Nocardia species. The respiratory tract is the most common site of infection, but primary cutaneous nocardiosis can also be induced by direct inoculation. Nocardiosis is usually reported in immunocompromised patients, such as those with human immunodeficiency virus (HIV) infection, chronic obstructive pulmonary disease, autoimmune diseases, cancer, or in those who have had organ transplantation or corticosteroid administration.

Introduction: Primary cutaneous nocardiosis is a rare suppurative or granulomatous inflammation disease caused by infection. Because of nonspecific clinical findings, it is always misdiagnosed as common pyogenic infection. Sulfonamides have been the standard treatment for nocardiosis, but the outcome is always poor due to the high rates of misdiagnosis and refractoriness of the disease. Read More

Background: Infections caused by nocardiae are rare, but misguided to clinicians, especially if there is a delay in the diagnosis and/or low response to chemotherapy. The incidence of nocardiosis is increasing constantly worldwide, and the situation is getting worse if we consider immunocompromised individuals, such as HIV positive patients since they are at higher risk. Surgical amputation, although not common, but should be considered as a result in some cases that cause partial disability. Read More

Background: Pulmonary nocardiosis frequently develops as an opportunistic infection in cell-mediated immunosuppressive patients, and sometimes requires differentiation from pulmonary malignancy. Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is a neoplastic disorder which leads to impaired cell-mediated immunity, and is commonly associated with small cell lung cancer (SCLC). Because pulmonary infection and causative malignancy can appear as pulmonary lesions with EAS, differentiation of these diseases remains a critical issue for physicians. Read More

Adrenal abscesses due to disseminated nocardiosis are exceedingly rare in clinical practice, and to date only 8 cases have been reported in the literature, most of which were confined to a single adrenal gland. These infections often occur in patients with underlying immune deficiency. We report a rare case of bilateral nocardial adrenal abscesses in an intravenous drug-using splenectomized patient that presumably originated from direct inoculation using intravenous opana, as his admission chest radiograph was normal.

Prompt and accurate diagnosis of skin infections is important in immunocompromised hosts, especially transplant patients. The sporotrichoid form, which is otherwise known as the lymphocutaneous form of skin involvement, can mimic other conditions, including those caused by fungi, mycobacteria, spirochetes, parasites and other bacteria. Delayed or inaccurate diagnosis and treatment of skin infections in transplant patients could lead to dissemination of disease and other poor outcomes. Read More

This study was conducted reviewing clinical records of 14 patients affected by nocardiosis over 5 years in a tertiary care hospital. Nocardia abscessus was responsible for one third of infections, deviating significantly from the results reported by other epidemiological investigations and highlighting the key role of molecular identification tests. Indeed, a precise identification of species is crucial for the determination of antibiotic sensitivity patterns and, consequently, for the choice of antibiotic treatment. Read More
