Abstract
We report 13 cases of pulmonary pneumocystis (PCP) in human immunodeficiency virus (HIV)-uninfected patients. Of eight males and five females, with a mean age of 55 years, one had breast neoplasia, two had common variable immunodeficiency (CVID), one had an autoimmune disease "Goodpasture's syndrome", and one had idiopathic fibrosis (nonspecific interstitial pneumonia/fibrosis (NIP)) undergoing prolonged corticosteroid therapy for two years, with no known immunosuppression in the remaining cases. The clinical picture was characterized by constant dyspnea and severe hypoxia in 11 cases. Lymphopenia was present in nine cases with an average rate of 920.76 elements/mm3. The diagnosis was confirmed by isolation of Pneumocystis jirovecii (PCJ) from induced sputum, except in two cases where analysis of bronchoalveolar lavage (BAL) fluid was required. With trimethoprim/sulfamethoxazole (TMP/SMX) and corticosteroid therapy, the course was favorable in all cases. Prophylactic treatment was indicated in three cases.

Time to trimethoprim/sulfamethoxazole initiation among patients with rheumatic disease complicated by Pneumocystis jirovecii pneumonia: impact on 90-day mortality. BMC Infect Dis 2022; 22:961. [PMID: 36575406 PMCID: PMC9793549 DOI: 10.1186/s12879-022-07940-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 12/12/2022] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Pneumocystis jirovecii pneumonia (PJP) is a life-threatening disease with increasing prevalence in patients with rheumatic disease. Trimethoprim/sulfamethoxazole (TMP/SMX) is an effective treatment for patients with rheumatic disease hospitalized for PJP. This study aimed to describe the 90-day mortality of patients with rheumatic disease complicated by PJP and investigate whether the administration of TMP/SMX after 7 days from initial symptoms correlates with 90-day mortality. METHODS We enrolled consecutive patients with rheumatic disease complicated with PJP in our center from August 2018 to August 2021. The participants were classified into two groups according to when TMP/SMX was initiated: early (within the first 7 days) and late (after 7 days). The primary outcome was 90-day PJP-related mortality. Multivariate cox regression and Kaplan-Meier survival analyses were conducted to identify the risk factors for mortality and examine differences in survival between early and late use of TMP/SMX. RESULTS Thirty-seven patients with rheumatic disease (median age 50.1 years, 24.3% male) complicated by PJP were enrolled in our study, and 15 (40.5%) patients died at or before 90 days of follow-up. The most common comorbidity was systemic lupus erythematosus (14, 37.8%), followed by inflammatory myopathy (11, 27.9%). Patients in the early group were less likely to require mechanical ventilation (8/27, 29.6% vs. 9/10, 90.0%, P = 0.002), lower doses glucocorticoids (43.2 mg/d vs. 72.2 mg/d, P = 0.039) and had lower mortality (7/27, 25.9% vs. 8/10, 80.0%, P = 0.006) than those in the late group. In the Kaplan-Meier analysis, the survivor probability of the early group was notably higher than that of the late group (P = 0.007). Multivariate cox regression analysis showed that initiation of TMP/SMX after 7 days from admission (hazard ratio [HR]: 5.9, 95% confidence interval [CI]: 1.1-30.4; P = 0.034) and a higher level of lactate dehydrogenase (LDH; HR: 6.0, 95% CI: 1.1-31.8; P = 0.035) were associated with 90-day mortality in patients with rheumatic disease complicated by PJP. CONCLUSION Patients with rheumatic disease complicated by PJP had poor prognoses, with mortality rates as high as 40.5%. TMP/SMX initiation after 7 days from initial symptoms and a higher level of serum LDH were significantly associated with increased 90-day mortality.

Abstract
The risk of patients with ALL and recipients of an allogeneic HSCT developing Pneumocystis jirovecii pneumonia is sufficiently high to warrant guidelines for the laboratory diagnosis, prevention and treatment of the disease. In this issue, the European Conference on Infections in Leukemia (ECIL) presents its recommendations in three companion papers.

Abstract
The initiation of systemic antimicrobial treatment of Pneumocystis jirovecii pneumonia (PCP) is triggered by clinical signs and symptoms, typical radiological and occasionally laboratory findings in patients at risk of this infection. Diagnostic proof by bronchoalveolar lavage should not delay the start of treatment. Most patients with haematological malignancies present with a severe PCP; therefore, antimicrobial therapy should be started intravenously. High-dose trimethoprim/sulfamethoxazole is the treatment of choice. In patients with documented intolerance to this regimen, the preferred alternative is the combination of primaquine plus clindamycin. Treatment success should be first evaluated after 1 week, and in case of clinical non-response, pulmonary CT scan and bronchoalveolar lavage should be repeated to look for secondary or co-infections. Treatment duration typically is 3 weeks and secondary anti-PCP prophylaxis is indicated in all patients thereafter. In patients with critical respiratory failure, non-invasive ventilation is not significantly superior to intubation and mechanical ventilation. The administration of glucocorticoids must be decided on a case-by-case basis.

Abstract
Pneumocystis pneumonia (PCP) is well known and described in AIDS patients. Due to the increasing use of cytotoxic and immunosuppressive therapies, the incidence of this infection has dramatically increased in the last years in patients with other predisposing immunodeficiencies and remains an important cause of morbidity and mortality in solid-organ transplant (SOT) recipients. PCP in HIV-negative patients, such as SOT patients, harbors some specificity compared to AIDS patients, which could change the medical management of these patients. This article summarizes the current knowledge on the epidemiology, risk factors, clinical manifestations, diagnoses, prevention, and treatment of Pneumocystis pneumonia in solid-organ transplant recipients, with a particular focus on the changes caused by the use of post-transplantation prophylaxis.

Abstract
Pneumocystis jirovecii is the only fungus of its kind to be pathogenic in humans. It is primarily responsible for pneumonia (PJP). The key to understanding immune defences has focused on T-cells, mainly because of the HIV infection epidemic. Patients presenting with PJP all have a CD4 count below 200/mm(3). The introduction of systematic primary prophylaxis and the use of new anti-retroviral drugs have significantly reduced the incidence of this disease in the HIV-infected population, mainly in developed countries. The increasingly frequent use of corticosteroids, chemotherapy, and other immunosuppressive drugs has led to an outbreak of PJP in patients not infected by HIV. These patients presenting with PJP have more rapid and severe symptoms, sometimes atypical, leading to delay the initiation of a specific anti-infective therapy, sometimes a cause of death. However, the contribution of new diagnostic tools and a better understanding of patients at risk should improve their survival.
