Background: Pneumocystis pneumonia (PCP) is a life-threatening fungal infection that can occur in kidney transplantation (KT) recipients. A growing number of KT recipients are receiving perioperative treatment with rituximab, which is associated with prolonged B-cell depletion and possible risk of PCP occurrence; however, the optimal prophylaxis duration according to rituximab treatment is yet unknown. We compared the occurrence of PCP and the duration of prophylaxis in KT recipients according to rituximab treatment.
Methods: We retrospectively analyzed 2110 patients who underwent KT between January 2009 and December 2016, who were divided into non-Rituximab group (n = 1588, 75.3%) and rituximab group (n = 522, 24.7%).
Results: In the rituximab group, the estimated number needed to treat (NNT) for prophylaxis prolongation from 6 to 12 months was 29.0 with a relative risk reduction of 90.0%. In the non-rituximab group, the estimated NNT value was 133.3 and the relative risk reduction was 66.4%. Rituximab treatment (hazard ratio (HR) = 3.09; P < 0.01) and acute rejection (HR = 2.19; P = 0.03) were significant risk factors for PCP in multivariate analysis.
Conclusions: Our results suggest that maintaining PCP prophylaxis for 12 months may be beneficial in KT recipients treated with rituximab for desensitization or acute rejection treatment.

Cytomegalovirus (CMV) infection remains one of the most common and challenging post-transplant infections. Children with inborn errors of immunity (IEI) and T-cell dysfunction are at high risk for CMV infection, which can be complicated by refractory and/or resistant cases. This case describes a Nepalese girl with MHC class II deficiency, who presented at 3 months of age with CMV and Pneumocystis jirovecii pneumonia.

Pneumonia caused by infection (PCP) is a potentially life-threatening illness, particularly affecting the immunocompromised. The past two decades have shown an increase in PCP incidence; however, the underlying factors that promote disease severity and fatality have yet to be fully elucidated. Recent evidence suggests that the microbiota of the respiratory tract may play a role in stimulating or repressing pulmonary inflammation, as well as the progression of both bacterial and viral pneumonia.

Pneumocystis jirovecii pneumonia (PJP) is an opportunistic fungal infection that often occurs secondary to human immunodeficiency virus (HIV) infection. However, for non-HIV immunocompromised patients, such as those undergoing novel immunosuppressive treatments to manage malignancies, organ transplants, or connective tissue diseases, PJP is emerging as an increasing threat. The clinical manifestations of PJP in HIV-infected and non-HIV-infected patients differ significantly.

Cytomegalovirus (CMV) pneumonia is an uncommon presentation of CMV among patients with HIV/AIDS, particularly in co-infection with pneumonia (PCP). A case was reported with a literature review, and a comprehensive literature search was performed using the PubMed/MEDLINE and Scopus databases. We report a 52-year-old male with AIDS presenting with progressively worsening dyspnea over 1 week.
