Nocardiosis is known as an opportunistic infection in immunocompromised hosts. We present to you a case of pleural nocardiosis in a 38-year-old male patient who was a chronic smoker and presented with a left-sided pleural effusion. He was a known case of thrombocytopenia due to immune thrombocytopenia (ITP) and was on steroid therapy. On admission, he was found to be positive for HIV. Pleural fluid was sent to microbiology, where acid-fast staining with 1% sulfuric acid (HSO)showed acid-fast branching filamentous rods and cultures grew which was resistant to ampicillin, ceftriaxone, imipenem, cotrimoxazole, erythromycin, tetracycline, and susceptible to amikacin, linezolid, and levofloxacin. The isolate was identified as using 16S rRNA gene sequencing. Culture from the chest wall drain grew and Subsequently, the patient developed sepsis, and paired blood cultures grew . Unfortunately, the patient could not survive despite aggressive efforts and died after 40 days of admission.

Article Synopsis
- Pulmonary nocardiosis (PN) is a rare opportunistic infection studied in southern China, focusing on clinical, radiological, and microbiological aspects along with treatment outcomes.
- The research included 67 PN patients, revealing that bronchiectasis was the most common respiratory condition, with cough and sputum as the major symptoms, while Nocardia farcinica was identified as the most prevalent pathogen.
- Factors linked to poor prognosis included a higher neutrophil-to-lymphocyte ratio, concurrent bacterial infections, and the use of carbapenems.

Article Synopsis
- Recurrent respiratory infections significantly impact individuals with Cystic Fibrosis (pwCF), and the role of Nocardia species as emerging pathogens necessitates further exploration in their management and clinical significance.
- A systematic review of 16 studies involving 89 pwCF highlighted the isolation of various Nocardia species, with co-infection present in 85% of cases and a notable decline in lung function observed in 23% of patients post-isolation.
- The findings emphasize the importance of prompt treatment following Nocardia strain isolation, with 93% of patients receiving immediate antibiotic therapy suited to their clinical conditions.
Comparison of clinical outcomes of pulmonary nocardiosis between AIDS and non-AIDS patients.

Article Synopsis
- Nocardia species can infect both healthy and immunocompromised individuals, prompting a study comparing outcomes in AIDS and non-AIDS patients with pulmonary nocardiosis in northeastern Thailand from 2009 to 2022.
- The study found that AIDS patients had higher rates of severe complications and mortality, particularly those with disseminated disease, highlighting a 7.93-fold increased risk of death within 30 days compared to non-AIDS patients.
- The authors conclude that early diagnosis and a multidrug treatment approach are crucial for managing pulmonary nocardiosis in resource-limited settings, especially for AIDS patients.

is a genus of aerobic, Gram-positive, partially acid-fast, filamentous bacilli notoriously known for causing multisystemic infections in immunocompromised individuals. Notably, this genus of bacteria commonly infects the pleural and central nervous system, leading to pneumonia and brain abscesses, respectively. Our patient is a 71-year-old female who initially presented to the emergency department complaining of shortness of breath and altered mental status.
