Opportunistic Infections, Mortality Risk, and Prevention Strategies in Patients With Vacuoles, E1 Enzyme, X-Linked, Autoinflammatory, Somatic (VEXAS) Syndrome. Open Forum Infect Dis 2024; 11:ofae405. [PMID: 39077052 PMCID: PMC11285395 DOI: 10.1093/ofid/ofae405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Accepted: 07/14/2024] [Indexed: 07/31/2024] Open
Abstract
Background VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome is a genetic disorder characterized by bone marrow failure and systemic inflammation, putting patients at risk for infections. This study comprehensively examines the prevalence of opportunistic infections in patients with VEXAS, evaluating their impact on clinical outcomes and potential preventive measures. Methods Patients with confirmed VEXAS were included. Survival analysis and logistic regression were used to identify associations between opportunistic infections and mortality. Infection rates (IRs) for Pneumocystis jirovecii pneumonia (PJP) and alphaherpesviruses were calculated over a prospective 8-month observation period in relationship to prophylaxis. Results Of 94 patients with VEXAS, 6% developed PJP; 15% had alphaherpesvirus reactivation, with varicella zoster virus (VZV) being the most common herpesvirus; and 10% contracted a nontuberculous mycobacterial (NTM) infection. Risk of death was significantly increased per month following a diagnosis of PJP (hazard ratio [HR], 72.41 [95% confidence interval {CI}, 13.67-533.70]) or NTM (HR, 29.09 [95% CI, 9.51-88.79]). Increased odds for death were also observed in patients with a history of herpes simplex virus (HSV) reactivation (odds ratio [OR], 12.10 [95% CI, 1.29-114.80]) but not in patients with VZV (OR, 0.89 [95% CI, .30-2.59]). Prophylaxis for PJP (IR, 0.001 vs 0 per person-day, P < .01) and VZV (IR, 0.006 vs 0 per person-day, P = .04) markedly decreased infection rates with a number needed to treat of 4 and 7, respectively. Conclusions Opportunistic infections are common in patients with VEXAS. Patients who develop PJP, HSV, or NTM are at increased risk for death. Prophylaxis against PJP and VZV is highly effective.

Abstract
Background Pneumocystis jirovecii pneumonia (PCP) has a significant mortality rate for non-HIV immunocompromised patients. Prevention is primarily based on combined trimethoprim and sulfamethoxazole (TMP-SMX) but guidelines on pneumocystosis prophylaxis are scattered and not consensual. Objectives This study aims to describe PCP in non-HIV patients and to review case by case the prior indication of prophylaxis according to specific guidelines.We included patients with confirmed diagnosis of PCP admitted to one university hospital from 2007 to 2020. Prior indication for pneumocystis prophylaxis was assessed according to the specific guidelines for the underlying pathology or treatment. Results Of 150 patients with a medical diagnosis of PCP, 78 were included. Four groups of underlying pathologies were identified: hematological pathologies (42%), autoimmune diseases (27%), organ transplantation (17%), and other pathologies at risk of PCP (14%). A small subgroup of 14 patients (18%) had received a prior prescription of pneumocystis prophylaxis but none at the time of the episode. Transfer to intensive care was necessary for 33 (42%) patients, and the mortality rate at 3 months was 20%. According to international disease society guidelines, 52 patients (59%) should have been on prophylaxis at the time of the pneumocystis episode. Lowest compliance with guidelines was observed in the hematological disease group for 24 patients (72%) without prescription of indicated prophylaxis. Conclusion Infectious disease specialists should draw up specific prophylactic guidelines against pneumocystis to promote a better prevention of the disease and include additional criteria in their recommendations according to individual characteristics to prevent fatal cases.

Abstract
BACKGROUND Pneumocystis jirovecii pneumonia (PJP) is a life-threatening opportunistic infection in immunocompromised children with systemic lupus erythematosus (SLE). Prophylaxis against PJP in high-risk children is crucial, but the risk factors for PJP in children with SLE are not adequately characterized. This study sought to identify the risk factors for PJP in long-term glucocorticoid-treated pediatric SLE patients. METHODS This study encompassed 71 treatment episodes involving 64 children with prolonged (≥4 weeks) high-dose (≥20 mg/d prednisone) steroid regimens. Fourteen treatment episodes involved the PJP, whereas others did not. Risk factors for PJP were assessed through Cox regression. The predictive value of these factors was evaluated using receiver operating characteristic curves. The incidence of PJP in different risk groups was compared using the Kaplan-Meier method. RESULTS The creatinine (hazard ratio, 1.009; 95% confidence interval [CI], 1.001-1.017; p = 0.021) and the lowest lymphocyte count (hazard ratio, 0.007; 95% CI, 0.000-0.373; p = 0.014) were independent risk factors for PJP in children with SLE. The receiver operating characteristic curve showed that using creatinine greater than 72.5 μmol/L and the lowest lymphocyte count less than 0.6 × 109/L as risk predictors for PJP resulted in an area under the curve value of 0.934 (95% CI, 0.870-0.997; p < 0.001). The study revealed a significant increase in PJP prevalence (p < 0.001) in children with elevated creatinine levels and low lymphocyte count. CONCLUSIONS Elevated levels of creatinine and decreased lymphocyte count are identified as distinct risk factors for PJP in children with SLE who receive prolonged high-dose steroid therapy.

Abstract
Objecive Patients with autoimmune hepatitis (AIH) reportedly have an impaired quality of life (QOL), mainly due to depression, even during remission. In addition, hypozincaemia has been demonstrated in patients with chronic liver disease, including AIH, and is known to be related to depression. Corticosteroids are known to cause mental instability. We therefore investigated the longitudinal association between zinc supplementation and changes in the mental status among AIH patients treated with corticosteroids. Materials This study enrolled 26 patients with serological remission of AIH routinely treated at our facility after excluding 15 patients who either discontinued polaprezinc (150 mg/day) within 24 months or interrupted treatment. Two questionnaires, the Chronic Liver Disease Questionnaire (CLDQ) and SF-36, were adopted to evaluate the QOL before and after zinc supplementation. Results Serum zinc levels were significantly elevated after zinc supplementation (p<0.0001). The CLDQ worry subscale significantly improved after zinc supplementation (p=0.017), but none of the SF-36 subscales was affected. Multivariate analyses demonstrated that daily prednisolone dosing was inversely related to both the CLDQ worry domain score (p=0.036) and the SF-36 mental health component (p=0.031). There was a significant negative correlation between the changes in the daily steroid dose and the CLDQ worry domain scores before and after zinc supplementation (p=0.006). No serious adverse events occurred during the observation period. Conclusion Zinc supplementation safely and efficiently improved mental impairment, possibly caused by continuous treatment with corticosteroids, in patients with AIH.

Abstract
Post-transplant Pneumocystis jirovecii pneumonia (PcP) is an uncommon but increasingly reported disease among solid organ transplantation (SOT) recipients, associated with significant morbidity and mortality. Although the introduction of PcP prophylaxis has reduced its overall incidence, its prevalence continues to be high, especially during the second year after transplant, the period following prophylaxis discontinuation. We recently described two cases of PcP occurring more than one year after heart transplantation (HT) in patients who were no longer receiving PcP prophylaxis according to the local protocol. In both cases, the disease was diagnosed following the diagnosis of a viral illness, resulting in a significantly increased risk for PcP. While current heart transplantation guidelines recommend Pneumocystis jirovecii prophylaxis for up to 6-12 months after transplantation, after that period they only suggest an extended prophylaxis regimen in high-risk patients. Recent studies have identified several new risk factors that may be linked to an increased risk of PcP infection, including medication regimens and patient characteristics. Similarly, the indication for PcP prophylaxis in non-HIV patients has been expanded in relation to the introduction of new medications and therapeutic regimens for immune-mediated diseases. In our experience, the first patient was successfully treated with non-invasive ventilation, while the second required tracheal intubation, invasive ventilation, and extracorporeal CO2 removal due to severe respiratory failure. The aim of this double case report is to review the current timing of PcP prophylaxis after HT, the specific potential risk factors for PcP after HT, and the determinants of a prompt diagnosis and therapeutic approach in critically ill patients. We will also present a possible proposal for future investigations on indications for long-term prophylaxis.

Association between the cumulative dose of glucocorticoids before the development of pneumonia and death in patients receiving long-term glucocorticoids: a secondary analysis based on a Chinese cohort study. Front Med (Lausanne) 2023; 10:1175855. [PMID: 37547616 PMCID: PMC10399627 DOI: 10.3389/fmed.2023.1175855] [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: 03/01/2023] [Accepted: 07/04/2023] [Indexed: 08/08/2023] Open
Abstract
Background The present study aimed to evaluate the association between the cumulative dose of glucocorticoids (GCs) and case fatality in hospitalized patients who developed pneumonia while receiving glucocorticoid therapy. Methods This retrospective cohort study included 625 patients receiving long-term GC treatment who were hospitalized with pneumonia (322 male and 303 female). Data were obtained from the Dryad Digital Repository and were used to perform secondary analysis. Multivariable Cox proportional hazard regression model and restricted cubic splines (RCS) were used to evaluate the association between the cumulative dose of GCs and case fatality. Sensitivity analyses and subgroup analyses were performed. Results The 30-day and 90-day death rates were 22.9 and 26.2%, respectively. After adjusting for potential confounders, compared with those in the lowest quintile (≤ 1.5 g), the Cox proportional hazard regression model analysis showed that patients with different cumulative doses of GCs (1.5 to 2.95, 2.95 to 5, 5 to 11.5, and > 11.5 g) had lower risks for 30-day death, with respective hazard ratios of 0.86 (95% CI, 0.52 to 1.42), 0.81 (0.49 to 1.33), 0.29 (0.15 to 0.55), and 0.42 (0.22 to 0.79). The multivariable-adjusted RCS analysis suggested a statistically significant N-shaped association between the cumulative dose of GCs and 30-day death. A higher cumulative dose of GC tended to first lead to an increase in 30-day death within 1.8 g, then to a statistically significant decrease until around 8 g [HR for 1 g = 0.82 (0.69 to 0.97)], and again to an increase afterward. Similar results were found in the subgroup analyses and sensitivity analyses. Conclusion N-shaped association between the cumulative dose of GCs and case fatality was observed in patients receiving long-term GC treatment who were hospitalized with pneumonia. Our findings may help physicians manage these patients.

Clin Rheumatol 2023; 42:269-276.

Abstract
OBJECTIVE To determine whether the combined use of glucocorticoid with other immunosuppressants increased the risk of Pneumocystis jirovecii pneumonia (PCP) in autoimmune inflammatory disease (AIID) patients. METHODS The data were collected from the PubMed, Cochrane Library, and Web of Science databases. We excluded HIV-infected patients and those < 16 years of age, and included patients who combined use of glucocorticoid with other immunosuppressants or used glucocorticoid alone. The number of patients who were affected by PCP after therapy as the primary outcome and the number of patients with fatal outcomes, which included death, endotracheal tube intubation, PO2 < 60 mmHg, and other serious clinical symptoms due to PCP, as the secondary outcome. Odds ratios with 95% confidence intervals and variance tests were used to analyze the data. RESULTS The outcomes showed that the combined use of glucocorticoid with other immunosuppressants increased the risk of PCP in AIID patients (odds ratio = 2.85, 95% confidence intervals 1.75 to 4.64, I2 = 0%, P < 0.0001), which may be a consequence of the drug regimen reducing the lymphocyte count. Furthermore, the prognosis of patients receiving this drug regimen was poorer than with glucocorticoid alone (odds ratio = 2.31, 95% confidence intervals 1.02 to 5.23, I2 = 0%, P = 0.04). CONCLUSION The combined use of glucocorticoid with other immunosuppressants increased the risk of PCP in AIID patients and resulted in poorer prognoses. It is therefore clear that appropriate prophylaxis was vital in AIID patients to minimize the risk of PCP. Key Points • We demonstrated that the combined use of glucocorticoid with other immunosuppressants increased the risk of PCP in AIID patients and resulted in poorer prognoses. • As there are no standard prophylactic guidelines, we wish this work will be evidence to guide clinical prophylaxis.

Abstract
INTRODUCTION Pneumocystis jirovecii is an opportunistic, human-specific fungus that causes Pneumocystis pneumonia (PCP). PCP symptoms are nonspecific. A patient with P. jirovecii and another lung infection faces a diagnostic challenge. It may be difficult to determine which of these agents is responsible for the clinical symptoms, preventing effective treatment. Diagnostic and treatment efforts have been made more difficult by the rising frequency with which coronavirus 2019 (COVID-19) and PCP co-occur. AREAS COVERED Herein, we provide a comprehensive review of clinical and pharmacological recommendations along with a literature review of PCP in immunocompromised patients focusing on HIV-uninfected patients. EXPERT OPINION PCP may be masked by identifying co-existing pathogens that are not necessarily responsible for the observed infection. Patients with severe form COVID-19 should be examined for underlying immunodeficiency, and co-infections must be considered as co-infection with P. jirovecii may worsen COVID-19's severity and fatality. PCP should be investigated in patients with PCP risk factors who come with pneumonia and suggestive radiographic symptoms but have not previously received PCP prophylaxis. PCP prophylaxis should be explored in individuals with various conditions that impair the immune system, depending on their PCP risk.

Abstract
OBJECTIVES To develop recommendations for the prevention of infection in adult patients with systemic autoimmune rheumatic diseases (SARD). METHODS Clinical research questions relevant to the objective of the document were identified by a panel of experts selected based on their experience in the field. Systematic reviews of the available evidence were conducted, and evidence was graded according to the Scottish Intercollegiate Guidelines Network criteria. Specific recommendations were made. RESULTS Five questions were selected, referring to prevention of infection by Pneumocystis jirovecii with trimethoprim/sulfamethoxazole, primary and secondary prophylactic measures against hepatitis B virus, vaccination against human papillomavirus, vaccination against Streptococcus pneumoniae and vaccination against influenza virus, making a total of 18 recommendations, structured by question, based on the evidence found for the different SARD and/or expert consensus. CONCLUSIONS There is enough evidence on the safety and efficacy of vaccinations and other prophylactic measures against the microorganisms reviewed in this document to specifically recommend them for patients with SARD.

Abstract
OBJECTIVES To explore clinical features of autoimmune inflammatory rheumatic disease (AIRD) patients with Pneumocystis jirovecii pneumonia (PJP) and identify potential risk factors and prognostic factors. METHODS AIRD patients who had respiratory symptoms and underwent Pneumocystis jirovecii detection were identified from the database in our department from November 2018 to October 2020. These patients were categorized into PJP and non-PJP groups according to the diagnostic criteria of PJP. Univariate and multivariate analysis were conducted. RESULTS 173 patients were enrolled and 46 of them had laboratory confirmed PJP. Glucocorticoid (GC) increased the risk of PJP in a dose-dependent manner. In addition, shorter duration of immunosuppressive therapy (IST), combination therapy with CsA, and chronic pulmonary comorbidities were also strongly associated with a higher risk of PJP. Combination of IgM and IgA could well identify AIRD patients with PJP from other AIRD patients with respiratory symptoms, with the optimal cutoff value of -0.96 g/L. 7 of 46 AIRD patients with PJP died (15.2%). Higher level of serum LDH, dyspnea, ARDS, and the presence of extensive ground glass opacity (GGO) in radiologic examinations were more common in deceased patients. CONCLUSIONS AIRD patients with high-dose GC treatment, recent initiation of IST, combination therapy with CsA, and history of chronic pulmonary diseases were associated with greater risks of PJP infection. PJP patients with a higher level of serum LDH, dyspnea, moderate and severe ARDS, and the presence of extensive GGO in radiologic examinations had poorer prognosis.

Evaluating the risk-to-benefit ratio of using cotrimoxazole as a pneumocystis pneumonia preventative intervention among pemphigus patients treated with rituximab: A retrospective study with 494 patients. Dermatol Ther 2021; 35:e15257. [PMID: 34890103 DOI: 10.1111/dth.15257] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Revised: 11/27/2021] [Accepted: 12/04/2021] [Indexed: 11/28/2022]
Abstract
Rituximab is widely used as the first-line treatment for pemphigus patients. Since it depletes the B cells, it increases the risk of infections. Here, we evaluated the prophylactic efficacy of cotrimoxazole in decreasing the risk of pneumocystis pneumonia (PCP) infection in the pemphigus patients treated with rituximab. The medical records of confirmed pemphigus patients receiving rituximab were evaluated in two groups; those who received cotrimoxazole as a prophylactic after rituximab and patients who only received rituximab without any prophylaxis. The occurrence of PCP infection was determined in each group and compared. Medical records of 494 patients, including 301 women and 193 men, with the mean age of 46.74 years were analyzed. The phenotypes of the disease were mucocutaneous (n = 364), mucosal (n = 88), and cutaneous (n = 42). Among them, 235 cases had received cotrimoxazole as a prophylaxis and 259 patients did not. The incidence of PCP in total patients was 2 (0.4%), one in each group. Accordingly, no significant difference was observed in the incidence of PCP between two groups (p = 0.84). Also, no cotrimoxazole-related side effect was observed in the treated group. It seems that due to the low incidence of PCP in pemphigus patients treated with rituximab, prophylactic cotrimoxazole therapy is not necessary and it only increases the overall therapy cost and might cause cotrimoxazole-related adverse effects in some patients. However, regarding its probable beneficial effect in patients with long-term history of immunosuppressive therapy, more studies are required.

Abstract
Background Minimal change disease (MCD) causes approximately 10% of nephrotic syndrome in adults. While glucocorticoids (GCs) effectively induce remission in MCD, the disease has a high relapse rate (50-75%), and repeated exposure to GCs is often required. The adverse effects of GCs are well recognized and commonly encountered with the high doses and recurrent courses used in MCD. Summary In this review, we will discuss the standard therapy of MCD in adults and then describe new therapeutic options in induction therapy and treatment of relapses in MCD, minimizing the exposure to GCs. Key Messages Steroid minimization strategies may decrease adverse effects in the treatment of MCD.

Abstract
OBJECTIVES To develop recommendations for the prevention of infection in adult patients with systemic autoimmune rheumatic diseases (SARD). METHODS Clinical research questions relevant to the objective of the document were identified by a panel of experts selected based on their experience in the field. Systematic reviews of the available evidence were conducted, and evidence was graded according to the Scottish Intercollegiate Guidelines Network criteria. Specific recommendations were made. RESULTS Five questions were selected, referring to prevention of infection by Pneumocystis jirovecii with trimethoprim/sulfamethoxazole, primary and secondary prophylactic measures against hepatitis B virus, vaccination against human papillomavirus, vaccination against Streptococcus pneumoniae and vaccination against influenza virus, making a total of 18 recommendations, structured by question, based on the evidence found for the different SARD and/or expert consensus. CONCLUSIONS There is enough evidence on the safety and efficacy of vaccinations and other prophylactic measures against the microorganisms reviewed in this document to specifically recommend them for patients with SARD.

Abstract
AIM The aim of the present study is to investigate the effect of long-term zinc supplementation, which is important for the activation of various enzymes that contribute to antioxidant and antifibrotic activities, on the improvement of serum fibrotic markers in patients with autoimmune hepatitis (AIH). METHODS A total of 38 patients with AIH under regular treatment at our hospital who provided their consent for being treated with polaprezinc (75 mg twice daily) were included and classified into 2 groups: the patients with zinc elevation (n = 27) and the patients without zinc elevation (n = 11). Serum biomarker of fibrosis, protein expression levels of matrix metalloproteinases (MMPs), and their inhibitors (TIMPs) were evaluated. RESULTS A significant difference was found between the variability of serum procollagen type Ⅲ and collagen type Ⅳ-7S between the 2 groups before and after zinc administration for more than 24 months (p = 0.043 and p = 0.049). In the patients with zinc elevation, no significant changes were found in collagenase (MMP-1 and MMP-13) before and after zinc administration, whereas a significant increase in the expression of gelatinase (MMP-2 and MMP-9) was found after administration (p = 0.021 and p = 0.005). As for the relative ratio of MMPs to TIMPs, only MMP-9 to TIMP-1 showed a significant increase (p = 0.004). CONCLUSIONS Long-term treatment with polaprezinc has been demonstrated to safely improve serum fibrosis indices through increases in MMP-2/-9 and MMP-9/TIMP-1 and is expected to be well combined with direct antifibrotic therapies such as molecularly targeted agents.

Abstract
Pneumocystis jirovecii pneumonia (PCP) is a life-threatening opportunistic infection in idiopathic membranous nephropathy (IMN) patients, who are treated with immunosuppressive drugs. However, the risk factors of infection and their prognosis are rarely investigated. We aimed to characterize the clinical manifestations of PCP in patients with IMN, and to understand their risk factors, so that we can provide early warnings to patients with high risk and potential poor prognosis. We conducted a retrospective observational study of IMN patients in a referral center in China, from Jan 2012 to Dec 2018. Clinical and laboratory data were collected separately at the time of IMN and PCP diagnosis. Patients with PCP were matched to those without by gender and age at a ratio of 1:4. The risk factors and prognostic factors were determined by univariate and multivariate logistic regression analysis. A total of 879 patients with IMN were included, with a median follow-up of 267 (interquartile range (IQR) 64,842) days. In total, 26 (2.96%) of them were diagnosed with PCP. The infection rate increased to 3.87% among patients who received corticosteroids, and it further increased to 5.49% in those received over 0.5mg/kg prednisone. Univariate analysis indicated that initial usage of corticosteroids, use of cyclophosphamide, reduced estimated glomerular filtration rate (eGFR), and higher 24-h proteinuria were related to the PCP susceptibility. Multivariate analysis revealed that corticosteroid treatment and reduced eGFR increased the risk of the Pneumocystis jirovecii infection. The case fatality rate of the PCP patients was 23.08%, and increased to 75% among patients requiring invasive ventilation. Univariate analysis indicated that pulmonary insufficiency, invasive ventilation, decreased eGFR, and increased lactate dehydrogenase at presentation were linked to poor prognosis. PCP is not rare in patients with IMN, especially those on corticosteroids, and presented with decreased eGFR. Considering the high case fatality rate, further studies are in need for prevention and management of these patients.

Abstract
Autoimmune hemolytic anemia (AIHA) may be frequently challenged by infectious complications, mainly as a result of immunosuppressive treatments administered. Furthermore, infectious agents are known triggers of AIHA onset and relapse. Although being risk factors for mortality, infections are an underestimated issue in AIHA. This review will collect the available evidence on the frequency and type of infectious complications in AIHA, detailing the risk related to each treatment (i.e., steroids, rituximab, splenectomy, classic immunosuppressive agents, and new target drugs). Moreover, we will briefly discuss the infectious complications in AIHA secondary to other diseases that harbor an intrinsic infectious risk (e.g., primary immunodeficiencies, systemic autoimmune diseases, lymphoproliferative disorders, solid organ and hematopoietic stem cell transplants). Finally, viral and bacterial reactivations during immune suppressive therapies will be discussed, along with suggested screening and prophylactic strategies.

Abstract
We present a case of a critically ill patient with coronavirus disease 2019 (COVID-19) found to have acquired immune deficiency syndrome and Pneumocystis jirovecii pneumonia (PCP). Coronavirus disease 2019 and PCP co-occurrence is increasingly reported and may complicate diagnostic and therapeutic strategies. Patients with severe COVID-19 should be screened for underlying immunocompromise and coinfections should be considered.

Abstract
Corticosteroids constitute a first-line therapy for adults and children suffering from nonmalignant immune-mediated hematologic diseases. However, high disease relapse rates during the tapering period or upon drug discontinuation result in long-term corticosteroid use that increases the risk of infection. This same concept applies to other immunosuppressive agents, such as antimetabolites, calcineurin inhibitors, and cyclophosphamide. Corticosteroids are associated with a length-of-treatment and dose-dependent risk for infection. Screening and antimicrobial prophylaxis against tuberculosis, hepatitis B, Strongyloides stercoralis, and Pneumocystis jirovecii pneumonia (PJP) might be indicated in patients who are scheduled to be on high-dose corticosteroids for >4 weeks (>30 mg of prednisone-equivalent dose [PEQ]) or in patients chronically treated (≥8 weeks of continuous or intermittent corticosteroid use) with moderate doses (≥15 to <30 mg PEQ). Antimetabolites (azathioprine, mycophenolate) increase the risk of progressive multifocal leukoencephalopathy (PML); however, other opportunistic infections and viral reactivation have also been reported. In case of new onset of neurological symptoms, PML needs to be considered, and an urgent neurology consultation should be obtained. Cyclophosphamide-induced myelosuppression can lead to serious infections related to neutropenia. PJP prophylaxis should be considered with combination therapy of cyclophosphamide and corticosteroids until a PEQ dose ≤ 5 mg/d is reached. Data on infectious risk when cyclosporine is used in patients with nonmalignant hematologic diseases are lacking. Discontinuation of any immunosuppressive agent during an episode of infection is recommended. In all patients, adherence to an age-based immunization schedule is appropriate.

Clinical characteristics and management of immune checkpoint inhibitor-related pneumonitis: A single-institution retrospective study. Cancer Med 2020; 10:188-198. [PMID: 33211395 PMCID: PMC7826478 DOI: 10.1002/cam4.3600] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Revised: 10/21/2020] [Accepted: 10/22/2020] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION The increasing application of immune checkpoint inhibitors (ICIs) will cause more checkpoint inhibitor-related pneumonitis (CIP), which is a common cause of ICI-related death. The clinical management of CIP needs further optimization. METHODS Patients who were managed at Peking Union Medical College Hospital (PUMCH) between February 2017 and December 2019 with a diagnosis of CIP were retrospectively analyzed. Clinical data including clinical manifestations, radiologic data, laboratory and bronchoscopy results, treatments, and outcomes were collected and analyzed. The Mann-Whitney test was used to compare patients with and without co-infections. RESULTS In total, 48 CIP cases in 42 patients were analyzed. The median time from the first dose of ICI to the onset of CIP was 1.9 months (range: 0.1-13.7). Grade 3-4 (G3-4) accounted for 30 cases (71.4%). The most common symptoms were cough (88.1%) and dyspnea (78.6%). The median starting dose of equivalent prednisone (EP) was 55 mg (range: 30-200) for all patients. The median total duration of glucocorticosteroids (GCS) treatment was 42.5 days (range: 15-89). Three patients (7.14%) died because of infection. A higher starting dose and longer duration of GCS (≥30 mg/day; p = 0.001) were associated with opportunistic infection. Chest computed tomography (CT) showed diverse and asymmetrical lesions. Twelve patients were re-challenged, and six patients developed recurrent CIP. CONCLUSIONS The clinical and imaging manifestations of CIP are various, and differential diagnosis of exclusion is essential. GCS at 1-2 mg/kg is feasible to treat CIP, but the duration of GCS ≥30 mg/day should be used with caution, given the high risk of acquired infections. Re-challenges of ICI are feasible, but the recurrence of CIP needs to be closely monitored.

Abstract
Background Invasive fungal pneumonia is a severe infectious disease with high mortality in immunocompromised patients. However, the clinical diagnosis of the pathogen(s) remains difficult since microbiological evidence is difficult to acquire. Case presentation Here, we report a case of pulmonary fungal infection detected by next-generation sequencing (NGS) of bronchoalveolar lavage fluid (BALF) in a 61-year-old male with corticosteroid-treated dermatomyositis. Cytomegalovirus and influenza A virus infections were confirmed by nucleic acid detection and treated with antiviral medicine. The patient had been diagnosed with severe pneumonia and treated with empiric broad-spectrum antibacterial and antifungal drugs before bronchoscopy was performed. The patient responded poorly to those empiric treatments. Three fungi were found by NGS in the BALF, namely, Pneumocystis jirovecii, Aspergillus fumigatus and Rhizopus oryzae. After adjusting the patient’s treatment plan according to the NGS results, he improved significantly. Conclusions This case highlights the combined application of NGS and traditional tests in the clinical diagnosis of pulmonary invasive fungal disease. NGS is proposed as an important adjunctive diagnostic approach for identifying uncommon pathogens.

Abstract
Infections, including opportunistic infections, are a major and frequent cause of morbidity and mortality in patients with systemic autoimmune and rheumatic diseases. Pneumocystis jirovecii pneumonia, classically considered to be typical of HIV patients, transplanted patients or patients treated with oncological chemotherapy, is appearing increasingly frequently in these patients. Therefore, rheumatologists should know its mechanism of production, clinical manifestations, treatment and prophylaxis, all of which are addressed in this review.

Abstract
To identify the risk factors of pneumonia in patients with Anti-N-methyl-D-aspartate (Anti-NMDA) receptor encephalitis.This is a retrospective study.Department of Neurology in West China Hospital of Sichuan University.Patients with a definitive diagnosis of anti-NMDA receptor encephalitis.Risk factors associated with pneumonia were examined by bivariate analysis and multivariate logistic regression model.A total of 104 patients were included in this study, of which 41% patients (n = 43) were diagnosed with pneumonia at 7 days (range: 4-40 days) after admission. The occurrence of pneumonia was associated with prolonged hospital stays, a higher rate of poor outcome, and extra healthcare costs. Risk factors associated with pneumonia included Glasgow coma scale score (GCS), abnormal movements and hypokalemia.Pneumonia is a common complication in anti-NMDA receptor encephalitis. In the present study, we found that disorders of consciousness, abnormal movements, and hypokalemia were independent risk factors for pneumonia in inpatients with anti-NMDA receptor encephalitis. Pneumonia prolongs the patients' hospital stay, hospitalization expenditures, and affects the patients' prognosis.

Abstract
Background Pneumocystis jirovecii (P. jirovecii) is an opportunistic fungal pathogen and the role of its colonization in pulmonary diseases has become a popular focus in recent years. The aim of this study was to develop a modified loop-mediated isothermal amplification (LAMP) assay for detection of Pneumocystis jirovecii (P. jirovecii) DNA amongst non-HIV patients with various pulmonary diseases and use it to examine the prevalence and assess the association of P. jirovecii colonization with clinical characteristics of these diseases. Methods We modified the previously reported LAMP assay for P. jirovecii by adding real-time detection. This method was used to detect P. jirovecii colonization in pulmonary samples collected from 403 non-HIV patients with various pulmonary diseases enrolled from 5 hospitals in China. We determined the prevalence of P. jirovecii colonization in 7 types of pulmonary diseases and assessed the association of P. jirovecii colonization with clinical characteristics of these diseases. Results The modified LAMP assay showed no cross-reactivity with other common pulmonary microbes and was 1000 times more sensitive than that of conventional PCR. Using the modified LAMP assay, we detected P. jirovecii colonization in 281 (69.7%) of the 403 patients enrolled. P. jirovecii colonization was more common in interstitial lung diseases than in chronic obstructive pulmonary disease (COPD) (84.6% vs 64.5%, P < 0.05). Patients with acute exacerbation of COPD had a higher prevalence of P. jirovecii colonization compared to patients with stabilized COPD (67.4% vs 43.3%, P < 0.05). P. jirovecii colonization was associated with decreased pulmonary function, increased levels of 1,3-β-D-glucan and C-reactive protein, and decreased levels of CD4+ T-cell counts (P < 0.05 for each). Approximately 70% of P. jirovecii colonized patients had confections with other fungi or bacteria. Conclusions We developed a modified LAMP assay for detecting P. jirovecii. Our multi-center study of 403 patients supports that P. jirovecii colonization is a risk factor for the development of pulmonary diseases and highlights the need to further study the pathogenesis and transmission of P. jirovecii colonization in pulmonary diseases.

Abstract
Immunosuppressants, targeted antibody therapies, and surgical splenectomy are amongst the treatment choices for immune-mediated non-malignant hematologic disorders, with infection being the most common non-hematological adverse event from these therapies. Corticosteroids are associated with a length-of-treatment and dose-dependent risk for infection, including opportunistic infections. Screening and antimicrobial prophylaxis against tuberculosis, Strongyloides stercoralis, and Pneumocystis jirovecii pneumonia, are indicated in selected patients on steroids and with certain risk factors for infection. Rituximab is associated with hepatitis B virus reactivation. All patients planned to be started on rituximab should be screened for hepatitis B surface antigen and total core antibody, with antiviral prophylaxis given depending on test results. In eculizumab treated patients, immunization against meningococcal serogroups ACWY and B is recommended. In addition, some guidelines suggest antibiotic prophylaxis for the duration of eculizumab treatment. In splenectomized patients, counseling and immunization are cornerstones of infection prevention. Several federal and society guidelines about immunizations and prophylactic antimicrobial therapies for patients treated with various immunosuppressive agents exist and are summarized in this manuscript in a clinical-focused table. In addition, management suggestions are made where no formal guidelines exist.

Abstract
OBJECTIVES To investigate the incidence of pneumocystis pneumonia (PCP) and its risk factors in patients with rheumatic disease receiving non-high-dose steroid treatment, along with the risks and benefits of PCP prophylaxis. METHODS This study included 28,292 treatment episodes with prolonged (≥ 4 weeks), non-high-dose steroids (low dose [< 15 mg/day, n = 27,227] and medium dose [≥ 15 to < 30 mg/day, n = 1065], based on prednisone) over a 14-year period. Risk factors for PCP and prophylactic effect of trimethoprim-sulfamethoxazole (TMP-SMX) were investigated if the 1-year incidence rate (IR) of PCP in each dose group was > 0.1/100 person-years. Cox regression with LASSO was used for analysis. RESULTS One-year PCP IR in the low-dose group was 0.01 (95% CI 0.001-0.03)/100 person-years, and only the medium-dose group showed eligible PCP IR for further analysis. In the medium-dose group, prophylactic TMP-SMX was administered in 45 treatment episodes while other episodes involved no prophylaxis (prophylaxis group vs. control group). In 1018.0 person-years, 5 PCP cases occurred exclusively in the control group, yielding an IR of 0.5 (0.2-1.2)/100 person-years. Concomitant steroid-pulse treatment and baseline lymphopenia were the most significant risk factors for PCP. Treatment episodes with at least one of these factors (n = 173, high-risk subgroup) showed higher 1-year PCP IR (3.4 (1.1-8.0)/100 person-years), while no PCP occurred in other treatment episodes. TMP-SMX numerically reduced the risk (adjusted HR = 0.2 (0.001-2.3)) in the high-risk subgroup. The IR of adverse drug reactions (ADRs) related to TMP-SMX was 41.5 (22.3-71.6)/100 person-years, including one serious ADR. The number needed to treat with TMP-SMX to prevent one PCP in the high-risk subgroup (31 (17-226)) was lower than the number needed to harm by serious ADR (45 (15-∞)). CONCLUSION Incidence of PCP in patients with rheumatic diseases receiving prolonged, medium-dose steroids depends on the presence of risk factors. Prophylactic TMP-SMX may have greater benefit than potential risk in the high-risk subgroup.

Abstract
Background Immunosuppressive therapy for connective tissue diseases (CTDs) increases risk for opportunistic infections including Pneumocystis pneumonia (PCP). High mortality rates are reported in CTD patients with PCP, which suggests a potential need for prophylaxis, but indications remain poorly defined. Wide variations in the use of PCP prophylaxis among rheumatologists have been documented. This study evaluated PCP prophylaxis patterns for CTD patients among infectious disease (ID) physicians. Methods An electronic survey was emailed to 1264 adult ID physicians who are members of the Infectious Diseases Society of America Emerging Infections Network. Results Six hundred thirty-one physicians responded to the survey. Respondents to the survey were more likely to work in academics (P = .02) and be early (<5 years) or late (≥25 years) in their careers (P = .0002). Forty-three percent (n = 269) made no recommendations for PCP prophylaxis in non-HIV patients. Of the 362 respondents who did make such recommendations, the greatest consensus for disease-based prophylaxis was for granulomatosis with polyangiitis (53%). For therapy-based prophylaxis, corticosteroids ≥20 mg/d was the most frequently cited indication (87%). Surrogate laboratory markers to aid in decisions about prophylaxis were not routinely used (21%). Although the majority recommended discontinuation of PCP prophylaxis with tapering of corticosteroids (65%), there was variability in the specific dose. Eighty-nine percent of respondents felt that guidelines about PCP prophylaxis would be helpful. Conclusions There is little consensus about PCP prophylaxis in CTDs among ID physicians. Guidelines for PCP prophylaxis would be helpful when caring for these complex patients.

Abstract
Objective: Pneumocystis pneumonia (PCP) is a serious complication in patients with rheumatic diseases who are receiving immunosuppressive therapy. These patients have a higher mortality from PCP than those with human immunodeficiency virus. We examined factors associated with poor prognosis in patients with rheumatic diseases and evaluated PCP treatment in this population. Methods: This retrospective, single-center, observational cohort study included 31 patients with rheumatic diseases who were admitted to Juntendo University Hospital for PCP treatment from June 2006 to December 2017. The primary outcome was non-disease-specific mortality at discharge. Results: The median age at PCP diagnosis was 64 years. The survival rate was 61.3% (19/31). Twelve patients died, in all cases due to respiratory failure due to PCP. Among variables at PCP diagnosis and those related to PCP treatment, the presence of coexisting pulmonary diseases and greater glucocorticoid dose at PCP diagnosis were associated with higher mortality. The mortality related to biological agents for PCP was low. Rapid tapering of glucocorticoids improved survivability. Conclusion: In the treatment of PCP in patients with rheumatic diseases, rapid tapering of glucocorticoids was associated with a higher survival rate than the use of conventional therapy.

Abstract
Pneumocystis pneumonia (PCP) caused by Pneumocystis jirovecii (pj) can lead to serious health consequences in patients with an immunocompromised system. Trimethoprim (TMP), used as first-line therapy in combination with sulfamethoxazole, is a selective but only moderately potent pj dihydrofolate reductase (pjDHFR) inhibitor, whereas non-clinical pjDHFR inhibitors, such as, piritrexim and trimetrexate are potent but non-selective pjDHFR inhibitors. To meet the clinical needs for a potent and selective pjDHFR inhibitor for PCP treatment, fourteen 6-substituted pyrido[3,2-d]pyrimidines were developed. Comparison of the amino acid residues in the active site of pjDHFR and human DHFR (hDHFR) revealed prominent amino acid differences which could be exploited to structurally design potent and selective pjDHFR inhibitors. Molecular modeling followed by enzyme assays of the compounds revealed 15 as the best compound of the series with an IC50 of 80 nM and 28-fold selectivity for inhibiting pjDHFR over hDHFR. Compound 15 serves as the lead analog for further structural variations to afford more potent and selective pjDHFR inhibitors.

Abstract
PURPOSE OF REVIEW Immunosuppressive therapy for connective tissue diseases (CTDs) is steadily becoming more intense. The resultant impairment in cell-mediated immunity has been accompanied by an increasing risk for opportunistic infection (OI). Pneumocystis pneumonia (PCP) has been recognized as an OI in patients with CTDs, but specific risk factors and precise indications for PCP prophylaxis remain poorly defined. This review was undertaken to update information on the risk of PCP in patients with CTDs and to examine current guidelines for PCP prophylaxis in this population. RECENT FINDINGS Data on the occurrence of PCP and indications for prophylaxis in patients with CTDs is sparse. Large systematic reviews did not incorporate patients with CTD secondary to the lack of randomized control trials. Upon reviewing guidelines published since 2015, prophylaxis for PCP is recommended only for patients with ANCA-positive vasculitis, specifically granulomatosis with polyangiitis (GPA), who are undergoing intense induction therapy. Evidence-based recommendations for the prophylaxis of PCP in patients with CTDs cannot be provided. There is expert consensus that PCP prophylaxis is warranted in patients with GPA undergoing induction therapy. Prophylaxis should perhaps also be considered for other CTD patients who are receiving similar intense immunosuppressive therapy especially if they are lymphopenic or have a low CD4 count.

Prophylactic effect of trimethoprim-sulfamethoxazole for pneumocystis pneumonia in patients with rheumatic diseases exposed to prolonged high-dose glucocorticoids. Ann Rheum Dis 2017; 77:644-649. [PMID: 29092853 PMCID: PMC5909751 DOI: 10.1136/annrheumdis-2017-211796] [Citation(s) in RCA: 145] [Impact Index Per Article: 20.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2017] [Revised: 10/01/2017] [Accepted: 10/22/2017] [Indexed: 12/25/2022]
Abstract
Objectives To investigate the efficacy and safety of trimethoprim/sulfamethoxazole (TMP-SMX) as primary prophylaxis for pneumocystis pneumonia (PCP) in patients with rheumatic diseases receiving high-dose steroids. Methods The study included 1522 treatment episodes with prolonged (≥4 weeks) high-dose (≥30 mg/day prednisone) steroids in 1092 patients over a 12-year period. Of these, 262 treatment episodes involved TMP-SMX (prophylaxis group) while other episodes involved no prophylaxis (control group). Differences in 1-year PCP incidence and its mortality between the two groups were estimated using Cox regression. To minimise baseline imbalance, propensity score matching was performed and efficacy outcome was mainly assessed in the postmatched population (n=235 in both groups). Results During a total of 1474.4 person-years, 30 PCP cases occurred with a mortality rate of 36.7%. One non-fatal case occurred in the prophylaxis group. TMP-SMX significantly reduced the 1-year PCP incidence (adjusted HR=0.07(95% CI 0.01 to 0.53)) and related mortality (adjusted HR=0.08 (95% CI 0.0006 to 0.71)) in the postmatched population. The result of the same analysis performed in the whole population was consistent with that of the primary analysis. Incidence rate of adverse drug reactions (ADR) related to TMP-SMX was 21.2 (14.8–29.3)/100 person-years. Only two serious ADRs (including one Stevens-Johnson syndrome case) occurred. The number needed to treat for preventing one PCP (52 (33–124)) was lower than the number needed to harm for serious ADR (131 (55–∞)). Conclusion TMP-SMX prophylaxis significantly reduces the PCP incidence with a favourable safety profile in patients with rheumatic disease receiving prolonged, high-dose steroids.

Abstract
Corticosteroids are frequently used to treat rheumatic diseases. Their use comes with several well-established risks, including osteoporosis, avascular necrosis, glaucoma, and diabetes. The risk of infection is of utmost concern and is well documented, although randomized controlled trials of short-term and lower-dose steroids have generally shown little or no increased risk. Observational studies from the real world, however, have consistently shown dose-dependent increases in risk for serious infections as well as certain opportunistic infections. In patients who begin chronic steroid therapy, vaccination and screening strategies should be used in an attempt to mitigate this risk.

Abstract
Pneumocystis jirovecii infection causes fulminant interstitial pneumonia (Pneumocystis pneumonia, PCP) in patients with rheumatoid arthritis (RA) who are receiving biological and/or nonbiological antirheumatic drugs. Recently, we encountered a PCP outbreak among RA outpatients at our institution. Hospital-acquired, person-to-person transmission appears to be the most likely mode of this cluster of P. jirovecii infection. Carriage of P. jirovecii seems a time-limited phenomenon in immunocompetent hosts, but in RA patients receiving antirheumatic therapy, clearance of this organism from the lungs is delayed. Carriers among RA patients can serve as sources and reservoirs of P. jirovecii infection for other susceptible patients in outpatient facilities. Development of PCP is a matter of time in such carriers. Considering the poor survival rates of PCP cases, prophylactic antibiotics should be considered for RA patients who are scheduled to receive antirheumatic therapy. Once a new case of PCP occurs, we should take prompt action not only to treat the PCP patient but also to prevent other patients from becoming new carriers of P. jirovecii. Short-term prophylaxis with trimethoprim-sulfamethoxazole is effective in controlling P. jirovecii infection and preventing future outbreaks of PCP among RA patients.
