INTRODUCTION: HIV-1 infection leads to chronic inflammation and to an increased risk of non-AIDS mortality. Our objective was to determine whether AIDS-defining events (ADEs) were associated with increased overall and cause-specific non-AIDS related mortality after antiretroviral therapy (ART) initiation. METHODS: We included HIV treatment-naïve adults from the Antiretroviral Therapy Cohort Collaboration (ART-CC) who initiated ART from 1996 to 2014. Causes of death were assigned using the Coding Causes of Death in HIV (CoDe) protocol...

Pneumocystis pneumonia is a serious complication that may affect immunosuppressed patients. The absence of reliable and safe therapeutic alternatives to trimethoprim-sulfamethoxazole (TMP/SMX) justifies the search for more effective and less toxic agents. In this study, the in vitro and in vivo anti-Pneumocystis jirovecii activity of iclaprim, a diaminopyrimidine compound that exerts its antimicrobial activity through the inhibition of dihydrofolate reductase (DHFR), as does TMP, was evaluated alone or in combination with SMX...

The association of Pneumocystis jirovecii pneumonia (PJP) and acute myeloid leukaemia (AML) is not clearly defined. In our experience of 291 patients with AML, 20 (14 males and 6 females, median age 56) developed PJP (incidence 6.8%). Thirteen patients (65%) survived until discharge from hospital. We conclude that PJP is not uncommon among patients with AML. In clinical care of AML, awareness of PJP should be heightened and prophylaxis should be considered.

Background: Infection is common cause of morbidity and mortality in systemic lupus erythematosus (SLE). Our objective was to determine incidence and types of infections, particularly opportunistic infections, in SLE patients receiving cyclophosphamide, and to identify contribution of variables like demographics, steroid, other immunosuppressives, white blood cell and absolute neutrophil count to infection risk. Patients and Methods: We did retrospective chart review of SLE patients in our institute over last 10 years, who received minimum six cyclophosphamide infusions...

In both the post and pre combination antiretroviral therapy (cART) era, Pneumocystis jirovecii and Toxoplasma gondii remain common opportunistic infectious agents. The common manifestations are pneumonia for P. jirovecii and brain abscess for T. gondii. Nevertheless, co-infection remains rare, and pulmonary toxoplasmosis is scarce, or may be underestimated because of its similarity with Pneumocystis jirovecii pneumonia. We reported an uncommon case of an AIDS patient (6 CD4 + T cells/mm³) with both pulmonary and cerebral toxoplasmosis associated with pneumocystis pneumonia...

Pneumocystis jirovecii is an opportunistic fungus causing Pneumocystis pneumonia primarily in immunosuppressed patients. However, immunocompetent individuals may become colonized and, as asymptomatic carriers, serve as reservoirs of the pathogen. Moreover, these asymptomatic carriers are at higher risk of developing pneumonia if favorable conditions occur. This study aimed to determine the prevalence of P. jirovecii in patients with various pulmonary diseases and to characterize the genetic diversity of organisms circulating in the studied population...

Background: The overall incidence of Pneumocystis jirovecii pneumonia (PJP) in solid organ transplant recipients is 5-15%. A timely diagnosis of PJP is difficult and relies on imaging and detection of the organism. Methods: We present a case series of four patients displaying hypercalcaemia with an eventual diagnosis of PJP and document the management of the outbreak with a multidisciplinary team approach. We discuss the underlying pathophysiology and previous reports of hypercalcaemia preceding a diagnosis of PJP...

Clinically significant cytomegalovirus (CMV) reactivation is not uncommon in patients with severe immunodeficiency secondary to underlying medical disorders or following aggressive immunosuppressive therapy. However, it is less frequently found in patients with low-grade haematological malignancies after nonintensive chemotherapy. We treated a patient at our centre for stage IVB follicular lymphoma with standard chemotherapy who successively developed CMV colitis associated with a CMV viral load of >3 million copies/ml...

A 36-year-old Danish man, living in Asia, was diagnosed with Pneumocystis pneumonia (PCP) and HIV in 2013 (CD4+ count: 6 cells/µL; viral load: 518 000 copies/mL). He initiated combination antiretroviral therapy. Later that year, he was also diagnosed with granulomatosis with polyangiitis and was treated with prednisolone. Despite complete viral suppression and increasing CD4+ count (162 cells/µL), he was readmitted with PCP in April 2015. Subsequently, he returned to Denmark (CD4+ count: 80 cells/µL, viral suppression)...

BACKGROUND: Diagnosis of pneumocystis pneumonia (PCP) relies on microscopic visualization of P. jirovecii, or detection of Pneumocystis DNA in respiratory specimens, which involves invasive procedures such as bronchoalveolar lavage. The (1-3)-β-D-glucan (BG) assay has been proposed as a less invasive and less expensive diagnostic test to rule out PCP. We therefore compared blood levels of BG in patients with PCP with those of patients with candidemia, chronic disseminated candidiasis (CDC), invasive aspergillosis, mucormycosis, and tuberculosis and those of healthy volunteers...

INTRODUCTION: The incidence of immune reconstitution inflammatory syndrome (IRIS) in HIV-infected patients after an episode of Pneumocystis jirovecii pneumonia (PJP) seems to be lower than with other opportunistic infections. We conducted an observational study in order to determine the incidence, clinical characteristics and outcome of patients diagnosed with PJP-related IRIS. METHODS: We conducted an observational study of HIV patients diagnosed with PJP-related IRIS from January 2000 to November 2015...

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 patients with chronic urticaria under methotrexate therapy.

Often life-threatening pulmonary fungal infections (PFIs) can occur in patients with rheumatoid arthritis (RA) receiving disease-modifying anti-rheumatic drugs (DMARDs). Most of the data concerning PFIs in RA patients come from case reports and retrospective case series. Of the ve most widely described PFIs, Pneumocystis jirovecii pneumonia (PJP) has rarely been seen outside Japan, pulmonary cryptococcosis has been diagnosed in only a small number of patients worldwide, pulmonary coccidioidomycosis has almost only been observed in endemic areas, the limited number of cases of pulmonary histoplasmosis have mainly occurred in the USA, and the rare cases of invasive pulmonary aspergillosis have only been encountered in leukopenic patients...
