Patients with pneumocystis pneumonia have a risk of progressing to acute respiratory failure necessitating admission to intensive care. The case described is of a patient with a newly diagnosed HIV infection presenting with pneumocystis pneumonia. Despite initiating the appropriate pharmacological treatment the patient's clinical condition deteriorated, and required both rescue pharmacological ...

This study reports on a first case of granulomatous Pneumocystis carinii pneumonia (PCP) in a human immunodeficiency virus-negative patient with antineutrophil cytoplasmic antibody-positive Wegener's granulomatosis whilst receiving immunosuppressive treatment. The patient presented with diffuse alveolar haemorrhage, pauci-immune rapid progressive glomerulonephritis and leukocytoclastic vasculit...

Pneumocystis pneumonia is a life threatening infection that usually presents with diffuse bilateral ground-glass infiltrates in immunocompromised patients. We report a case of a single nodular granulomatous Pneumocystis pneumonia in a male with diffuse large B-cell lymphoma after R-CHOP therapy. He presented with symptoms of productive cough, dyspnea, and right-sided pleuritic chest pain that f...

Pneumocystis jirovecci is an opportunist fungal agent that usually causes pneumonia in immunocompromised patients, particularly those presenting with AIDS. In rare cases, this fungus can cause pneumonia in immunocompetent patients. The symptomatology in this case is acute and fulminant. We report the case of a Pneumocystis jirovecci pneumonia in a young patient initially admitted for acute resp...

BACKGROUND Airborne transmission of Pneumocystis has been demonstrated in animal models and is highly probable in humans. However, information concerning burdens of Pneumocystis jirovecii (human-derived Pneumocystis) in exhaled air from infected patients is lacking. Our objective is to evaluate P. jirovecii air diffusion in patients with Pneumocystis pneumonia. METHODS Patients admitted with ...

BACKGROUND When Pneumocystis DNA is recovered from respiratory specimens of patients without Pneumocystis pneumonia (PCP), patients are said to be colonised with Pneumocystis, although the significance of this state is unknown. Understanding risk factors for and outcomes of colonisation may provide insights into the life cycle and transmission dynamics of Pneumocystis jirovecii. METHODS We pe...

METHODS Pneumocystis carinii pneumonia occasionally appears in immunodeficient patients. While several reports have shown that Pneumocystis carinii pneumonia occurred in the early phase of starting infliximab treatment in patients with Crohn's disease (CD), the present case suggests for the first time that an increased dosage of infliximab may also lead to pneumonia. RESULTS A 51-year-old mal...

OBJECTIVE To assess the predisposing immunocompromised states, administration of pneumocystis jirovecii pneumonia prophylaxis, the disease course and outcomes of patients with pneumocystis jirovecii pneumonia. METHODS The retrospective study was conducted at the Aga Khan University Hospital in Karachi. The medical records of patients diagnosed with pneumocystis jirovecii pneumonia from Januar...

We report a case of HSV type 2 pneumonia in an HIV infected patient. The patient was empirically treated for severe Pneumocystis jiroveci community acquired pneumonia. Bronchoscopy with bronchoalveolar lavage was done, the cytology of which was negative for Pneumocystis jiroveci. All cultures were negative. HSV type 2 was isolated from BAL on culture. The patient died of pulmonary embolism. The...

Methotrexate has immunosuppressive effects and is administered for refractory chronic urticaria. We present a case of Pneumocystis jirovecii pneumonia in a patient with refractory chronic urticaria managed by low-dose weekly methotrexate treatment (total cumulative dose 195mg). Our study highlights the importance of providing prompt diagnosis and treatment of Pneumocystis jirovecii pneumonia in...
