The Development and Evaluation of a Prediction Model for Kidney Transplant-Based Pneumocystis carinii Pneumonia Patients Based on Hematological Indicators. Biomedicines 2024; 12:366. [PMID: 38397968 PMCID: PMC10886538 DOI: 10.3390/biomedicines12020366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 01/21/2024] [Accepted: 01/31/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND This study aimed to develop a simple predictive model for early identification of the risk of adverse outcomes in kidney transplant-associated Pneumocystis carinii pneumonia (PCP) patients. METHODS This study encompassed 103 patients diagnosed with PCP, who received treatment at our hospital between 2018 and 2023. Among these participants, 20 were categorized as suffering from severe PCP, and, regrettably, 13 among them succumbed. Through the application of machine learning techniques and multivariate logistic regression analysis, two pivotal variables were discerned and subsequently integrated into a nomogram. The efficacy of the model was assessed via receiver operating characteristic (ROC) curves and calibration curves. Additionally, decision curve analysis (DCA) and a clinical impact curve (CIC) were employed to evaluate the clinical utility of the model. The Kaplan-Meier (KM) survival curves were utilized to ascertain the model's aptitude for risk stratification. RESULTS Hematological markers, namely Procalcitonin (PCT) and C-reactive protein (CRP)-to-albumin ratio (CAR), were identified through machine learning and multivariate logistic regression. These variables were subsequently utilized to formulate a predictive model, presented in the form of a nomogram. The ROC curve exhibited commendable predictive accuracy in both internal validation (AUC = 0.861) and external validation (AUC = 0.896). Within a specific threshold probability range, both DCA and CIC demonstrated notable performance. Moreover, the KM survival curve further substantiated the nomogram's efficacy in risk stratification. CONCLUSIONS Based on hematological parameters, especially CAR and PCT, a simple nomogram was established to stratify prognostic risk in patients with renal transplant-related PCP.

Abstract
Background Pneumocystis jirovecii pneumonia (PJP) remains a significant threat in immunocompromised cases. Recent data on epidemiology and risk factors for PJP in non-HIV cases are scarce, and guidelines on appropriate prophylaxis are lacking. Methods In this multicenter retrospective trial, all non-HIV adult cases admitted to hospitals in Québec City, Canada, between January 2011 and January 2021 with a diagnosis of PJP were assessed for eligibility. Results An overall 129 cases of PJP were included. More than two-thirds had an underlying hematologic disease or an autoimmune/inflammatory condition. Prior to diagnosis, 83.7% were taking corticosteroids, 71.3% immunosuppressive agents (alone or in combination with corticosteroids), and 62% both. A diagnosis of PJP was noted in 22 patients receiving corticosteroids for treatment <28 days. Two patients developed PJP while undergoing corticosteroid monotherapy at a mean daily prednisone-equivalent dose <20 mg/d; 4.7% of our cohort received a PJP prophylaxis. Current recommendations or accepted clinical practices for PJP prophylaxis would not have applied to 48.8% of our patients. Conclusions The use of corticosteroids-in monotherapy or in coadministration with other immunosuppressive agents-remains the principal risk factor for PJP in the non-HIV population. Current prophylaxis guidelines and accepted practices are insufficient to adequately prevent PJP and need to be broadened and updated.

Dermatol Ther (Heidelb) 2023:10.1007/s13555-023-00953-9. [PMID: 37322166 DOI: 10.1007/s13555-023-00953-9] [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: 05/05/2023] [Accepted: 05/30/2023] [Indexed: 06/17/2023] Open
Abstract
INTRODUCTION Pneumocystis jirovecii pneumonia (PJP) is a severe, life-threatening complication in patients treated with rituximab. However, there is no consensus on the primary prophylaxis for it in rituximab-treated pemphigus patients. Therefore, we sought to investigate the prophylactic efficacy and safety profile of cotrimoxazole for reducing the risk of developing PJP in pemphigus patients receiving rituximab. METHODS This single-center retrospective study investigated 148 pemphigus patients undergoing a first cycle of rituximab between 2008 and 2021 at a tertiary referral center in northern Taiwan. Patients were divided into the prophylaxis group (N = 113) and the control group (N = 35) according to whether or not cotrimoxazole was administered. The primary outcome was the 1-year incidence of PJP in the two groups, while the secondary outcome was the incidence of cotrimoxazole-related adverse events. RESULTS Of the 148 patients enrolled in this study, three patients, all in the control group, developed PJP during the 1-year follow-up. The incidence of PJP (8.6%) in the control group was significantly higher than that in the prophylaxis group (0%) (p = 0.012). The incidence of cotrimoxazole-related adverse events was 2.7%, and none of the cases were associated with life-threatening conditions. In addition, the cumulative prednisolone dose was associated with a trend of a higher risk of PJP (p = 0.0483). CONCLUSIONS Prophylactic cotrimoxazole significantly reduces the risk of PJP in a certain high-risk population and has a tolerable safety profile.

Abstract
A woman in her 80s was admitted with 5 days of progressive dyspnoea and hypoxic respiratory failure, in the setting of receiving a 3-week course of low-dose to moderate-dose prednisolone for a pruritic skin rash. Her medical history was not significant for major medical comorbidities or any other clear risk factors for secondary immunosuppression apart from advanced age. CT revealed widespread small-airway and parenchymal disease with ground-glass opacities consistent with atypical respiratory infection. Sputum PCR confirmed Pneumocystis jirovecii She was diagnosed with Pneumocystis jirovecii pneumonia (PJP) in the context of her clinical presentation, radiological features and PCR result. Her HIV status was negative. The patient was treated with 4 weeks of trimethoprim-sulfamethoxazole and 3 weeks of adjunctive prednisolone. She initially required high-dependency unit support with non-invasive ventilation. In this case report, we review the literature regarding PJP in the dermatology setting.

Abstract
PURPOSE In the era of effective prophylaxis, the objective of this study was to describe pneumocystis pneumonia (PCP) patients' profile and evaluate the consistency of clinical situations encountered with the recommended indications for prophylaxis. METHODS This was a single-centre, retrospective study. All adults (> 18 years) with a definitive diagnosis of PCP were included. Data were collected from patients' electronic medical files. RESULTS The study examined the medical files of 225 patients diagnosed with PCP and treated between 1 January, 2015, and 30 June, 2020. More than 95% of the patients were not on anti-PCP prophylaxis at the time of PCP diagnosis. There were 32 (14%) deaths before the end of PCP treatment, mainly in auto-immune disease (30%) and solid tumours (38%) groups unlike the solid-organ transplants group, among whom deaths were infrequent. Indeed, 48% of our cohort (n = 107) had both corticosteroid (CS) therapy, immunosuppressive or immunomodulatory treatment, and lymphopaenia and could have been considered at high risk for PCP. Trimethoprim/sulfamethoxazole was administered as first-line PCP curative treatment in 95% of the patients. Toxicities of this drug led to treatment interruption in 25% of the patients (except death). CONCLUSIONS This study found a high number of PCP cases over 5 years. Unsurprisingly, most of the patients were immunosuppressed, with risk factors for PCP already described in the literature. This large number of PCP cases should be avoidable and, consequently, questions arise. Faced with these data, prophylaxis should be common sense for immunocompromised patients with risk factors, even if formalised recommendations do not exist.

Abstract
Purpose While early adjunctive corticosteroid therapy (EACST) has been proven effective in HIV patients with Pneumocystis Jirovecii Pneumonia (PJP), data remains controversial concerning non-HIV oncology or haematology patients. Methods This retrospective study included cancer patients without HIV and with diagnosis of PJP admitted in a cancer referral centre, from January-1-2010 to March-31-2017. We compared 30-day and 1-year mortality rate, change in the respiratory item of the Sequential Organ Failure Assessment score(SOFA-resp worsening), use of tracheal intubation between day-1 and day-5 of anti-pneumocystis therapy and occurrence of coinfections between patients with EACST and those with no or late corticosteroid therapy, using an inverse probability weighting propensity score-based (IPW) analysis. Results 133 non-HIV oncology or haematology PJP patients were included (EACST n = 58, others n = 75). The main underlying conditions were haematological malignancies (n = 107, 80,5%), solid tumour (n = 27, 20,3%) and allogeneic stem cell transplantation (n = 17, 12,8%). Overall 30-day and 1-year mortality rate was 24,1% and 56,4%, respectively. IPW analysis found no difference on 30-day (HR = 1.45, 95% CI [0.7–3.04], p = 0.321) and 1-year (HR = 1.25, CI 95% [0.75–2.09], p = 0.39) mortality rate between groups. Conclusion No difference in SOFA-resp worsening, tracheal intubation and coinfections was found between groups. Combination of EACST with anti-pneumocystis therapy in non-HIV onco-haematology PJP-patients was not associated with clinical improvement.

Abstract
For individuals who are immunocompromised, the opportunistic fungal pathogen Pneumocystis jirovecii is capable of causing life-threatening pneumonia as the causative agent of Pneumocystis pneumonia (PCP). PCP remains an acquired immunodeficiency disease (AIDS)-defining illness in the era of antiretroviral therapy. In addition, a rise in non-human immunodeficiency virus (HIV)-associated PCP has been observed due to increased usage of immunosuppressive and immunomodulating therapies. With the persistence of HIV-related PCP cases and associated morbidity and mortality, as well as difficult to diagnose non-HIV-related PCP cases, an improvement over current treatment and prevention standards is warranted. Current therapeutic strategies have primarily focused on the administration of trimethoprim-sulfamethoxazole, which is effective at disease prevention. However, current treatments are inadequate for treatment of PCP and prevention of PCP-related death, as evidenced by consistently high mortality rates for those hospitalized with PCP. There are no vaccines in clinical trials for the prevention of PCP, and significant obstacles exist that have slowed development, including host range specificity, and the inability to culture Pneumocystis spp. in vitro. In this review, we overview the immune response to Pneumocystis spp., and discuss current progress on novel vaccines and therapies currently in the preclinical and clinical pipeline.

Abstract
In the non-AIDS group, several underlying conditions and immune defects could lead to different PCP presentations. This study compared PCP presentation and outcome according to the underlying disease. A secondary analysis of a previously published prospective observational study including 544 PCP patients was done. Only non-AIDS patients were included. Underlying disease was defined as chronic lymphocytic leukemia (CLL), organ transplantation, solid cancer, allogeneic hematopoietic stem cell transplant (AHSCT), other hematological diseases, and immunosuppressive treatment. Clinical characteristics and outcomes were compared between groups. Multiple correspondent analyses compared clinical characteristics at diagnosis. Day 30 mortality was analyzed. Three hundred and twenty-one patients were included in the study. The underlying diseases were hematological malignancy (n = 75), AHSCT (n = 14), CLL (n = 19), solid organ transplant (n = 94), solid tumor (n = 39), and immunosuppressive treatment (n = 57). Compared with other underlying diseases, PCP related to CLL was closer to PCP related to AIDS presentation (long duration of symptoms before diagnosis, high level of dyspnea, and low oxygen saturation at diagnosis). Day 30 mortality was associated with underlying disease, oxygen flow, and shock at ICU admission. PCP presentations may vary according to the underlying reason for immunosuppression. Response to treatment and adjuvant steroid therapy should be analyzed regarding this result.

Abstract
BACKGROUND Dermatomyositis (DM) in an auto-immune inflammatory myopathy with skin lesions, and, occasionally, organ involvement. Herein, we report a case of DM during anti-MDA5 antibody therapy associated with interstitial lung disease (ILD) and pneumocystosis. PATIENTS AND METHODS A 64-year-old woman was hospitalized for impairment of her general health and skin lesions. Dermatological examination revealed classic signs of DM associated with hyperkeratotic papules on the palm creases. This led us to suspect DM with anti-MDA5 antibodies, which was subsequently confirmed by immunologic tests. We also noted dysphonia, exertional dyspnea and proximal muscles weakness. Despite early corticosteroid therapy, combined later with azathioprine, the patient's dyspnoea worsened; one month later, sudden pulmonary decompensation resulted in her admission to intensive care. A chest scan showed evidence of ILD and infectious signs, and the bronchoalveolar lavage was positive for Pneumocystisjiroveci. Despite treatment of this opportunist infection with cotrimoxazole and intensified immunosuppression, the patient died in intensive care. DISCUSSION Anti-MDA5 antibodies are associated with a specific clinical phenotype and a high degree of risk that should alert the dermatologist to the high likelihood of ILD having a poor prognosis. Associated clinical signs are erythematous, hyperkeratotic or ulcerated papules on the palm creases, as well as fingertip or periungual ulcerations or digital necrosis. This situation is associated with a high risk of pneumocystosis. However, no recommendations concerning prophylaxis are currently available.

Diagnostic accuracy of the 1,3-β-D-glucan test for pneumocystis pneumonia in a tertiary university hospital in Denmark: A retrospective study. Med Mycol 2020; 57:710-717. [PMID: 30535059 DOI: 10.1093/mmy/myy129] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Revised: 10/30/2018] [Accepted: 11/06/2018] [Indexed: 01/03/2023] Open
Abstract
1,3-β-D-glucan (BG), a cell-wall component of most fungi including Pneumocystis (PC), is recommended by international guidelines for screening for pneumocystis pneumonia (PCP) in hematologic patients. We retrospectively validated the BG test in our tertiary university hospital. Forty-five patients (median age 53 years, 33% female) tested for PC by polymerase chain reaction (PCR) and/or immunoflourescence (IF)-microscopy with a stored blood sample within ±5 days of the PC test were tested by the Fungitell (cutoff <60 and >80 pg/ml). Cases had symptoms and radiology compatible with PCP and positive IF-microscopy (proven PCP, n = 8) or positive PCR (probable PCP, n = 10). Controls had no compatible symptoms/radiology and negative tests for PC on conventional testing (no PCP, n = 24), or positive PCR/IF-microscopy (colonized, n = 3). Median BG-levels were 1108 pg/ml (proven PCP), 612 pg/ml (probable PCP), 29 pg/ml (colonized), and 48 pg/ml (controls, P < 0.001). Compared to the PCP case/control classification, the BG test showed sensitivities of 83-89% and specificities of 64-74%, positive likelihood ratio (LR) of 3.2 and negative LR of 0.23 at recommended cutoff and moderate agreement between tests. Optimal cutoff was ≥73 pg/ml. In PCR-positive cases, the agreement between the BG test and IF-microscopy was 78-89% with fair/moderate agreement. Elevated BG levels were seen in controls with probable invasive fungal infections (n = 4), hemodialysis, bacterial infections and/or betalactams. To conclude, 11% of patients with PCP would be missed if the BG test had been used for diagnosing PCP. Specificity was moderate. Among PCR-positive patients, the BG test identified more cases than IF-microscopy. BG testing is potentially helpful but sensitivity is insufficient to exclude PCP.

Abstract
Purpose To analyze the clinical characteristics of Pneumocystis pneumonia (PCP) in renal transplant recipients, identify early sensitivity indicators, and optimize clinical strategies. Patients and Methods We retrospectively analyzed clinical data for 24 patients with confirmed PCP who underwent renal transplantation (RT) between 2010 and 2019, encompassing a mean follow-up of 29 (range, 11-49) d. Results A 71% incidence was observed for PCP during the first 6 months after RT. Progressive dyspnea (79%) was the most common symptom, followed by fever (75%) and dry cough (67%). In the initial phase of PCP, the most frequent computerized tomography (CT) finding was the presence of symmetric, apically distributed ground-glass opacities. Nine of 11 patients (82%) were diagnosed by induced sputum testing, 14 of 17 (82%) by bronchoalveolar lavage, and 1 of 24 (4%) by sputum smear. The 1,3-β-D-glucan level was elevated (mean, 259.16 ± 392.34 pg/mL) in 80% of patients, while 75% had elevated C-reactive protein levels (median, 37.85 mg/L). Two of 18 patients (11%) were positive for cytomegalovirus. All patients were treated with trimethoprim-sulfamethoxazole (3 doses of 1-6 g/kg) and third-generation cephalosporin or moxifloxacin monotherapy to prevent bacterial infection. The methylprednisolone dose (40-400 mg/d) varied according to illness. Most patients were treated using a nasal cannula or oxygen mask, and 2 by mechanical ventilation. CT showed improved lesions after treatment, and completely absorbed lesions or residual fibrosis at follow-up. The mean hospitalization cost was 14,644.73 ± 11,101.59 RMB. Conclusion Peak PCP incidence occurred during the first 6 months after surgery. Progressive dyspnea, fever, and dry cough are important indicators for PCP. Bilateral and diffuse ground-glass opacities involving both lung apexes are often the first indication for PCP diagnosis. Induced sputum testing may be the method-of-choice for pathogen detection. The cure rate can be improved through early antipathogen, glucocorticoid, and preventive anti-infection therapies, as well as respiratory support.

Abstract
RATIONALE The incidence of Pneumocystis jirovecii pneumonia (PjP) is rising. Longer time to treatment is associated with higher mortality. OBJECTIVES To develop a multivariable risk prediction model for PjP diagnosis. METHODS In a prospective multicenter cohort of ICU patients with hematological malignancies and acute respiratory failure, factors associated with documented PjP were identified. The risk prediction model was tested in an independent prospective multicenter cohort. We assessed discrimination (by areas under the receiver operating characteristic curves [AUCs]) and goodness of fit (by Hosmer-Lemeshow statistics). Model performance was assessed using 30 sets of imputed data sets. MEASUREMENTS AND MAIN RESULTS Among the 1,330 patients, 134 of 1,092 (12.3%; 95% confidence interval [CI], 10.4-14.4%) had proven PjP in the derivation cohort, as did 15 of 238 (6.3%, 95% CI, 3.6-10.2%) in the validation cohort. The model included age, lymphoproliferative disease, anti-Pneumocystis prophylaxis, the number of days between respiratory symptom onset and ICU admission, shock, chest radiograph pattern, and pleural effusion. The median (interquartile range) score was 3.5 (1.5-5.0) (range, -3.5 to 8.5) in the derivation cohort and 1.0 (0-2.0) (range, -3.5 to 6.0) in the validation cohort. The best threshold was defined on the validation sample as 3, allowing us to reach 86.7% sensitivity and 67.7% specificity for PjP, with a negative predictive value of 97.9% in the case of 10% prevalence. The score had good calibration (goodness of fit, -0.75) and discrimination in the derivation cohort (mean AUC, 0.80; 95% CI, 0.76-0.84) and validation cohort (mean AUC, 0.83; 95% CI, 0.72-0.93). CONCLUSIONS The PjP score for hematology patients with acute respiratory failure can be computed at admission, based on readily available variables. Potential clinical benefits of using this score deserve assessment.

Abstract
Importance Pneumocystis pneumonia (PCP) is a potentially lethal opportunistic infection that primary prophylaxis can help prevent. The risk of prophylactic therapy must be weighed against the incidence of PCP in the patient population. Prophylaxis most frequently involves trimethoprim-sulfamethoxazole, with second-line therapies, including atovaquone, dapsone, and pentamide. The indication for prophylaxis in immunocompromised patients without HIV is less well defined. Previously, an incidence of at least 3.5% has been proposed as a cutoff to justify prophylaxis. Objective To assess the incidence of PCP in patients with autoimmune blistering diseases receiving no routine prophylaxis. Design, Setting, and Participants This was a retrospective analysis of patient medical records to determine the incidence of PCP infections. The multicenter study was performed at tertiary care centers that provide care for patients with autoimmune blistering disease in Germany, Italy, Singapore, Israel, and the Netherlands. Patients had a confirmed diagnosis of pemphigus vulgaris/foliaceus, bullous pemphigoid, epidermolysis bullosa acquisita, mucous membrane pemphigoid/cicatricial pemphigoid, or anti-p200 pemphigoid. Main Outcomes and Measures To determine the incidence of PCP defined as patients with the International Classification of Diseases, Ninth Revision (ICD-9), code 136.3, for PCP, or free text documentation of PCP occurring based on characteristic radiographic findings with elevated lactate dehydrogenase, or hospitalization for pneumonia with bronchioalveolar lavage demonstrating Pneumocystis jiroveci on confirmatory stains. Results A total of 801 patients with autoimmune blistering diseases were included in this study; their mean (SD) age was 66.5 (17.6) years, and a total of 465 (58%) were female. Only 1 patient developed PCP, resulting in an incidence rate of 0.1%. This incidence significantly fell below the recommended threshold of 3.5% (0.1% vs 3.5%, χ21 = 27.0; P < .001). This incidence was significantly lower than the previously reported incidence of PCP in all immunosuppressed dermatologic patients (0.1% vs 1.3%; χ21 = 8.2; P = .004). Conclusions and Relevance Routine Pneumocystis prophylaxis for patients with autoimmune blistering diseases does not seem to be warranted. Patients with autoimmune blistering disease seem to have a lower risk of PCP than the general population of immunosuppressed dermatology patients. Risks of routine prophylaxis include hyperkalemia, hypoglycemia, photosensitivity, thrombocytopenia, and more rare adverse reactions.

Abstract
AIMS Pneumocystis Jirovecii (PJ) is regarded as an agent of fungal infection and in cases of pneumocystis pneumonia (PCP) in immune-compromised patients including cancer patients. It is not clear what kinds of cancer, treatments, and environment need prophylaxis for PCP. In this study, we have analyzed the detectability of PJ DNA from sputum, and discussed prophylaxis and risk factors regarding PCP. METHODS A total of forty-nine materials (twenty-four from outpatients during cancer chemotherapies and twenty-five from healthy control subjects) was collected. Their PJ DNAs were amplified using nested PCR with specific primers of the PJ gene (the mitochondrial small subunit rRNA gene). RESULTS PJ DNA was detectable in 46% of specimens (sputum) from cancer patients during chemotherapies, and incidences of not significantly different among types of cancer and chemotherapy regimens. Prophylactic use of Sulfamethoxazole/Trimetoprim (ST) reduced the detection of PJ DNA. Detection of PJ DNA is not high among healthy non-smokers (20%) and high among healthy smokers (47%). CONCLUSIONS Prophylactic use of ST may be necessary for cancer patients during chemotherapies. Also, smoking may be associated with PJ colonization in the airway and air vesicles, and may increase the mortality rate for PCP. All patients undergoing cancer chemotherapies should cease smoking.

Abstract
BACKGROUND Opportunistic infections (OIs) are a dreaded adverse effect of immunosuppressive therapy, leading to the use of opportunistic infection prophylaxis (OIP) in many immunosuppressed conditions. However, guidelines for OIP in pemphigus are lacking. OBJECTIVE Our objective was to evaluate the approach of leading pemphigus experts towards OIP. METHODS We conducted an online survey of OIP trends. RESULTS The survey was completed by 33 experts. Prior to initiation of immunosuppressive therapy, 75% routinely screened for hepatitis viruses, and at least half screened for HIV or tuberculosis. Most experts (76%) prescribed OIP but to <10% of their patients, and the most frequent drugs of choice were sulfamethoxazole/trimethoprim and acyclovir. Most experts agreed that treatment with three or more immunosuppressive agents or a previous history of OIs would lead to the use of OIP that was then discontinued with cessation of immunosuppression. The arguments against OIP were the lack of evidence for its necessity and concern about side effects or emergence of resistant pathogens. The surveyed experts treated patients with severe disease in a tertiary care setting, which may have led to an overestimation of the use of OIP. Infectious disease specialists were not included. CONCLUSION Substantial disparities exist in approaches to OIP for patients with pemphigus, including the decision to treat, type of treatment, and risk stratification among pemphigus experts.

Abstract
BACKGROUND Dermatomyositis associated with anti-MDA-5 autoantibodies is a recently-described clinical entity. Herein we report two lethal cases involving pneumocystis pneumonia. PATIENTS AND METHODS Case no 1. A 56-year-old male patient developed cutaneous symptoms consistent with dermatomyositis without muscular involvement. Antinuclear antibodies were present and anti-MDA5 auto-antibodies were identified. The scan showed interstitial lung disease without infection. Significant improvement was obtained with corticosteroids. One month later, the patient presented acute respiratory illness (hypoxemia: PaO2 60mmHg, exacerbation of lung disease evidenced by a scan, and diagnosis of pneumocystis pneumonia on bronchoalveolar lavage). He died despite appropriate antibiotic therapy and immunosuppressant therapy. Case no 2. The second case concerned a 52-year-old Vietnamese man who developed more atypical cutaneous symptoms of dermatomyositis without muscular involvement. ANAb responses were positive (1/400) and MDA5 was present. The patient was treated with corticosteroids (40mg/d), hydroxychloroquine, and intravenous immunoglobulin. After significant improvement, the patient developed an acute respiratory illness due to superinfection with pneumocystis and he died despite specific treatment and cyclophosphamide bolus. CONCLUSION In dermatomyositis, anti-MDA5 antibody screening is essential for the prognosis since the disease carries a risk of complication with severe lung disease. Bronchial fibroscopy with bronchoalveolar lavage should be considered at the time of diagnosis. Our two cases suggest the need for early screening for pneumocystis pneumonia in the event of respiratory distress and possibly for prophylactic treatment at the start of immunosuppressant therapy.
