RESUMEN

BACKGROUND: The long-term efficacy and safety of mepolizumab for treatment of severe eosinophilic asthma are well established. Here, we examine the clinical impact of stopping mepolizumab after long-term use. METHODS: COMET (NCT02555371) was a randomised, double-blind, placebo-controlled, parallel-group, multicentre study. Patients who had completed COLUMBA (NCT01691859) or COSMEX (NCT02135692) and received continuous mepolizumab treatment for ≥3 years were randomised 1:1 to stop (switch to placebo) or continue subcutaneous mepolizumab 100 mg every 4 weeks for 52 weeks. Primary end-point: time to first clinically significant exacerbation; secondary end-points: time to first exacerbation requiring hospitalisation/emergency department visit, time to decrease in asthma control (≥0.5-point increase in Asthma Control Questionnaire-5 score from COMET baseline) and blood eosinophil count ratio to COMET baseline. Safety was assessed. RESULTS: Patients stopping (n=151) versus continuing (n=144) mepolizumab had significantly shorter times to first clinically significant exacerbation (hazard ratio 1.61, 95% CI 1.17-2.22; p=0.004) and decrease in asthma control (hazard ratio 1.52, 95% CI 1.13-2.02; p=0.005), and higher blood eosinophil counts at week 52 (270 versus 40 cells·µL-1; ratio (stopping versus continuing) 6.19, 95% CI 4.89-7.83; p<0.001). Differences in efficacy outcomes between groups were observed when assessed from week 12 (16 weeks after last mepolizumab dose). Exacerbations requiring hospitalisation/emergency department visit were rare. Adverse events in patients continuing mepolizumab were consistent with previous studies. For patients who stopped mepolizumab, the safety profile was consistent with other eosinophilic asthma populations. CONCLUSION: Patients who stopped mepolizumab had an increase in exacerbations and reduced asthma control versus those who continued.

RESUMEN

INTRODUCTION: Pneumocystis jirovecii pneumonia (PCP) can occur in HIV patients but also in those without HIV (non-HIV PCP) but with other causes of immunodeficiency including malignancy or rheumatic diseases. OBJECTIVE AND METHODS: To evaluate the clinical presentation and prognostic factors of non-HIV PCP, we retrospectively reviewed all patients diagnosed as having PCP without HIV at Kameda Medical Center, Chiba, Japan, from January 2005 until June 2012. For the purpose of examining a prognostic factor for non-HIV PCP with 30-day mortality, we compared the characteristics of patients, clinical symptoms, radiological images, Eastern Cooperative Oncology Group performance status (PS), and the time from the onset of respiratory symptoms to the start of therapy, in both survival and fatality groups. RESULTS: A total of 38 patients were eligible in this study. Twenty-five survived and 13 had died. The non-HIV PCP patients in the survivor group had a better PS and received anti-PCP therapy earlier than those in the nonsurvivor group. Rales upon auscultation and respiratory failure at initial visits were seen more frequently in the nonsurvivor group than in the survivor group. Lactate dehydrogenase and C-reactive protein values tended to be higher in the nonsurvivor group, but this was not statistically significant. Multivariate analyses using 5 variables showed that a poor PS of 2-4 was an independent risk factor for non-HIV PCP patients and resulted in death (odds ratio 15.24; 95% confidence interval 1.72-135.21). CONCLUSION: We suggest that poor PS is an independent risk factor in non-HIV PCP, and a patient's PS and disease activity may correlate with outcome.

RESUMEN

BACKGROUND: In Japan and other societies with rapidly aging populations, recurrent pneumonia (RP) is a major clinical problem yet only limited information exists regarding the burden of this disease. METHODS: A prospective study of adult pneumonia was conducted to investigate the incidence of RP and potential risk factors. From February 1, 2012 to January 31, 2013, patients aged ≥ 15 years who were diagnosed with pneumonia were prospectively enrolled in a representative community hospital located in central Japan. Patients were followed for one-year to evaluate the recurrence of pneumonia and characteristics associated with RP. Cox proportional hazards models were constructed to compute adjusted hazard ratios (aHR) and ascertain risk factors significantly associated with RP. RESULTS: In total, 841 patients with a median age of 73 years (range 15-101 years) were enrolled totaling 1,048 person-years of observation with a median follow-up time of 475 days. A total of 137 patients had at least one recurrent episode with an incidence rate of 13.1 per 100 person-years (95% confidence interval: 11.1-15.5). In multivariate analysis, a past history of pneumonia (aHR 1.95, 95% CI: 1.35-2.8), chronic pulmonary disease (aHR 1.86, 1.24-2.78) and inhaled corticosteroid usage (aHR 1.78, 1.12-2.84) and hypnotic/sedative medication usage (aHR 2.06, 1.28-3.31) were identified as independent risk factors for recurrent pneumonia, whereas angiotensin converting enzyme-inhibitors usage was associated with a reduction of the risk of RP (aHR 0.22, 0.05-0.91). The detection of P. aeruginosa was significantly associated with RP even after adjusting for chronic pulmonary diseases (aHR = 2.37). CONCLUSIONS: Recurrent pneumonia constitutes a considerable proportion of the pneumonia burden in Japan. A past history of pneumonia, chronic pulmonary disease, inhaled corticosteroid and hypnotic/sedative medication usage and detection of P. aeruginosa were identified as independent risk factors for recurrent pneumonia and special attention regarding the use of medications in this vulnerable population is needed to reduce the impact of this disease in aging populations.

RESUMEN

BACKGROUND: Long-acting ß2-agonists (LABA) and leukotriene receptor antagonists (LTRA) are two principal agents that can be added to inhaled corticosteroids (ICS) for patients with asthma that is not adequately controlled by ICS alone. In our previous study, the Gly16Arg genotype of the ß2-adrenergic receptor (ADRB2) gene did not influence the differential bronchodilator effect of salmeterol versus montelukast as an add-on therapy to ICS within 16 weeks of follow-up (the J-Blossom study). METHODS: We examined if genes encoding CYSLTR1, CYSLTR2, PTGER2 or PTGER4 could explain differential responses to salmeterol versus montelukast using the participants of the J-Blossom study. This study included 76 patients with mild-to-moderate asthma. The difference in peak expiratory flow (PEF) (ΔPEF, l/min) after 16 weeks of treatment with salmeterol (ΔPEFsal) versus montelukast (ΔPEFmon) was associated with the genotypes at each of 4 genes. In addition, multivariate analyses were used to identify a gene-gene interaction between ADRB2 gene and each of these 4 genes. RESULTS: Although none of 4 genes were associated with ΔPEFsal-ΔPEFmon in the univariate analyses, multivariate analysis showed that PTGER4 gene, interacting with ADRB2 Gly16Arg, was associated with ΔPEFsal-ΔPEFmon (p=0.0032). CONCLUSION: Our findings suggested that the interactions between two genetic loci at ADRB2 and PTGER4 is important in determining the differential response to salmeterol versus montelukast in patients with chronic adult asthma.

RESUMEN

AIM: To elucidate the characteristics of patients with asthma who have specific IgE responses to inhaled allergens detected by ImmunoCAP, which is not detectable by MAST-26. METHODS: A total of 168 patients with adult asthma who reside in the Kanto region were recruited. Levels of total serum IgE and allergen specific IgE antibodies towards 14 common inhaled allergens (MAST-26) were measured. Among these samples, 48 patients with no detectable allergen-specific IgE (group A) and 44 patients with strong sensitization to Dermatophagoides farinae (group B) were selected for further assessment of their sensitization to inhaled allergens such as cockroach and moth using ImmunoCAP. RESULTS: In group A, ImmunoCAP detected specific IgE responses to some inhaled allergens in 27.1% of the patients. The strongest predictive factor for the presence of allergen-specific IgE responses detected by ImmunoCAP was elevated levels of total serum IgE (p=0.0007). In group B, the presence of IgE responses specific to cockroach or moth by ImmunoCAP were found in 27.8% or 52.3% of the patients, respectively. The predictive factor for the presence of these positive IgE responses was also elevated levels of total serum IgE (p=0.0003). CONCLUSION: Asthma patients with no detectable specific IgE responses to any inhaled allergens by MAST-26 may be still sensitized to common inhaled allergens, including cockroach and moth. Thus, the presence of allergen-specific IgE responses may be re-assessed by ImmunoCAP in patients with asthma, especially when patients have higher levels of total serum IgE.

RESUMEN

BACKGROUND: Long-acting ß2-agonists and leukotriene receptor antagonists are two principal agents that can be added to inhaled corticosteroids (ICS) for patients with asthma that is not adequately controlled by ICS alone. The Gly16Arg genotype of the ß2-adrenergic receptor (ADRB2) gene may influence the bronchodilator effects of ß2-agonists. We hypothesized that differential responses to long-acting ß2-agonists or leukotriene receptor antagonists might be determined partly by the Gly16Arg polymorphism in Japanese asthma patients. MATERIALS AND METHODS: This randomized, genotype-stratified, two-period crossover study included 80 patients with mild-to-moderate asthma (35 Arg/Arg and 45 Gly/Gly individuals). The primary study outcome was the difference in peak expiratory flow (ΔPEF) (ΔPEF, l/min) by genotype after 16 weeks of treatment with salmeterol (ΔPEFsal) or montelukast (ΔPEFmon). In addition, multivariate analyses were used to identify independent factors that were predictive of responses to each treatment. RESULTS: The mean ΔPEFsal-ΔPEFmon was 19.3±46.6 among Arg/Arg individuals and 16.8±51.5 among Gly/Gly individuals, indicating that the Gly16Arg genotype did not influence the differential bronchodilator effect of the two agents. Multivariate analysis showed that higher peripheral eosinophil counts were associated with better response to salmeterol (P<0.05). CONCLUSION: The Gly16Arg genotype did not influence the differential bronchodilator effect of salmeterol or montelukast as an add-on therapy to ICS within 16 weeks of follow-up. Higher peripheral eosinophil counts may be associated with better responses to salmeterol in combination with ICS.

RESUMEN

INTRODUCTION: Acute exacerbation (AE) of chronic obstructive pulmonary disease (COPD) is a fatal event, leading to poor outcomes among COPD patients. However, exact frequency and poor prognostic factors are not well known in Japan. METHODS: and patients, To assess the frequency and risk factors of AE, we performed this prospective cohort study at the Kameda Medical Center in Japan between during 2011 and 2013. AE was defined as an acute worsening of respiratory symptoms according to the GOLD guideline. Furthermore, we compared the exacerbation-free time between the groups. RESULTS: A total of 330 patients (230 COPD patients and 100 smoking controls) were enrolled in the study. The mean age in the study was 73 years, and 94% of the patients were male. As for the frequency of AE, 0.17 times/patients/year was found in all patients. The frequency of AE increased as the COPD disease severity (p = 0.042 by Jonch-Heere terpla test). GOLD I patients had longer exacerbation-free time than GOLD II, and GOLD II grade COPD patients had longer exacerbation-free time than GOLD III grade COPD patients. In terms of risk factors for AE, logistic regression analysis showed that Modified Medical Research Council (mMRC) scale ≥3 and FEV1.0% <50% were independent poor prognostic factors for moderate grade of AE events, and mMRC scale ≥3 was independent poor prognostic factor for severe AE events. CONCLUSION: The frequency of AE increases as the disease severity becomes more severe. We found mMRC scale >3 and FEV1 <50% were risk factors for AE-COPD.

RESUMEN

Influenza related to complications such as pneumonia and encephalitis have sporadically been reported. However, influenza A (H1N1)-virus-associated hemophagocytic syndrome (VAHS) has rarely been reported. A 39-year old woman complained of high fever and was referred to us. Chest infiltrations in both lungs and a positive polymerase chain reaction (PCR) for novel swine origin influenza A (H1N1) in bronchial alveolar lavage fluid (BALF) specimen was confirmed and she was diagnosed with influenza A (H1N1) pneumonia. Pancytopenia was found, and hemophagocytic syndrome (HPS) was diagnosed by bone marrow aspiration. Following intravenous administration of antiflu drug and combination therapy of steroid pulse and erythromycin IV, the patient's respiratory dysfunction and lab data gradually improved and she was discharged on day 21. Whereas secondary HPS related to viral infections such as Epstein­Barr virus, cytomegalovirus, and human herpesvirus type 6 are commonly seen, H1N1 pneumonia complicated with secondary VAHS is rare.

RESUMEN

The mortality of Pneumocystis pneumonia (PCP) patients without human immunodeficiency virus (HIV) infection ranges from 0 to 70 %, whereas that of HIV-infected PCP patients ranges from 10 to 20 %. The reasons for these differences are not known. We retrospectively analyzed factors contributing to the survival of 23 patients with PCP and without HIV infection, in whom PCP developed as community-acquired pneumonia (CAP). The interval from admission to the start of PCP-specific treatment was significantly shorter for survivors (2.71 ± 3.64 days; n = 14) than for non-survivors (8.67 ± 5.5 days; n = 9; p = 0.003). Moreover, although the severity scores/classes assessed by A-DROP, CURB-65, and PSI were no different on admission, scores/classes at the start of PCP-specific treatment were significantly higher for non-survivors. Overall mortality was 39 %, but mortality was approximately 70-100 % for patients classified as severe grade by A-DROP, CURB-65, or PSI scores/classes at the time when PCP-specific treatment was started, which was far higher than expected for these guidelines. In conclusion, early diagnosis and treatment within 3 days are crucial for the survival of PCP patients without HIV infection. We emphasize the limitations of application of guidelines for CAP to patients with PCP.

RESUMEN

Pneumocystis pneumonia (PCP) can occur in patients with many causes of the immunocompromised state other than human immunodeficiency virus (HIV). It is quite difficult to diagnose PCP without HIV because there is no method for detecting Pneumocystis jirovecii. Thus, non-HIV PCP continues to have high mortality. Recently, loop-mediated isothermal amplification (LAMP) is becoming an established nucleic acid amplification method offering rapid, accurate, and cost-effective diagnosis of infectious diseases. We report a non-HIV PCP case successfully diagnosed by the LAMP method. It was previously reported that PCR in BALF specimens had been the most sensitive method in the diagnosis of PCP without HIV. The LAMP method would be more sensitive than conventional PCR and an effective tool in the early diagnosis of PCP.

RESUMEN

While Pneumocystis jirovecii pneumonia (PCP) can occur in immunocompromised patients with HIV infection, the prognosis of non-HIV PCP is still poor, showing a high mortality rate of 30%-75%. The pathophysiological mechanism of non-HIV PCP is quite different from that of HIV-PCP. Aging, underlying disease, dysbiotic gut microbiome, and Th1 predominance, leads to macrophagic polarization shifting from M2 to M1. These cause dysregulation in the host immunity against P. jirovecii, resulting in severe lung injury and a high mortality rate among non-HIV PCP patients. This review describes poor prognostic factors, an issue of predictive values used for general pneumonia practice, and new aspects, including the dysbiosis of the gut microbiome and macrophagic polarization in the treatment of non-HIV PCP.

RESUMEN

Asthma worsening and symptom control are clinically important health outcomes in patients with severe eosinophilic asthma. This analysis of COMET evaluated whether stopping versus continuing long-term mepolizumab therapy impacted these outcomes. Patients with severe eosinophilic asthma with ≥3 years continuous mepolizumab treatment (via COLUMBA (NCT01691859) or COSMEX (NCT02135692) open-label studies) were eligible to enter COMET (NCT02555371), a randomised, double-blind, placebo-controlled study. Patients were randomised 1:1 to continue mepolizumab 100 mg subcutaneous every 4 weeks or to stop mepolizumab, plus standard of care asthma treatment. Patients could switch to open-label mepolizumab following an exacerbation. Health outcome endpoints included time to first asthma worsening (composite endpoint: rescue use, symptoms, awakening at night and morning peak expiratory flow (PEF)), patient and clinician assessed global rating of asthma severity and overall perception of response to therapy, and unscheduled healthcare resource utilisation. Patients who stopped mepolizumab showed increased risk of and shorter time to first asthma worsening compared with those who continued mepolizumab (hazard ratio (HR) 1.71; 95% CI 1.17-2.52; p=0.006), including reduced asthma control (increased risk of first worsening in rescue use (HR 1.36; 95% CI 1.00-1.84; p=0.047) and morning PEF (HR 1.77; 95% CI 1.21-2.59; p=0.003). There was a higher probability of any unscheduled healthcare resource use (HR 1.81; 95% CI 1.31-2.49; p<0.001), and patients and clinicians reported greater asthma severity and less favourable perceived response to therapy for patients who stopped versus continued mepolizumab. These data suggest that patients with severe eosinophilic asthma continuing long-term mepolizumab treatment sustain clinically important improvements in health outcomes.

RESUMEN

To evaluate the efficacy and safety of single-dose 2.0 g azithromycin (ZSR) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AE-COPD), we retrospectively reviewed all patients with AE-COPD who were treated with ZSR. In comparison with patients who received intravenous therapy for AE-COPD, the clinical cure rate, length of stay in hospital, and medical costs were evaluated. A total of 29 patients thus were eligible for this study. Clinical cure rates of ZSR and intravenous therapy for the treatment of AE-COPD were 83.3% (n = 12) and 88.2% (n = 17), respectively, between the groups (P = 1.000). No severe adverse events were found in either group. The ZSR and intravenous groups averaged 9.9 and 12.5 days of admission, respectively. Length of admission for clinical success cases was much shorter for patients who received ZSR than patients who received intravenous therapy (6.2 vs. 11.9 days, P = 0.038). Medical costs were less for the group receiving ZSR than for the intravenous therapy group. We suggest ZSR can achieve near-perfect compliance and could be one of the tools in the treatment of AE-COPD.

RESUMEN

A 36-year-old man with a history of asthma visited an outpatient clinic complaining of high fever and general fatigue, and was diagnosed as having influenza type A by influenza antigen test. Laboratory findings revealed mild inflammation, mild acidemia, and hypercapnea with radiologic infiltrations in the right lung, and remarkable wheezes in both lungs were heard on auscultation. He was diagnosed with asthma exacerbation and having influenza pneumonia, and was referred to us. Therapy was begun with oseltamivir for influenza infection and intravenous infusions of betamethasone and aminophylline with non-invasive pulmonary ventilation for asthma exacerbation and acute respiratory failure. Although he was weaned from mechanical ventilation and his general condition became good, electrocardiogram showed sinus bradycardia and negative T waves in V1-4 without any symptoms. Blood test and echocardiography showed almost normal findings except for slight elevation of LDH and AST. Influenza A antigen was already confirmed and he was diagnosed as having influenza myocarditis clinically. Although it is well known that influenza can cause asthma exacerbation and encephalopathy, influenza myocarditis is regarded as rare by physicians. In fact, the number of case reports about influenza myocarditis is few. Myocarditis may not appear to be serious, but could cause fatal arrhythmia and heart failure. All clinicians should be aware of the overall clinical picture and the possibility of severe complications of myocarditis caused by flu infection.

RESUMEN

Among conventional oxygen therapies there are currently no devices which can supply a high oxygen level of over 60%. The HighFO nebulizer (Koike Medical) is a new device which is able to supply an oxygen flow rate of over 35l/min, and a high concentration of oxygen. We report 2 cases of type I respiratory failure managed by the HighFO nebulizer. Case 1: A 70-year-old man with lung cancer had an acute exacerbation of radiation pneumonitis during chemoradiotherapy. We gave him an oxygen mask with a reserve bag, but his condition worsened. We then used the HighFO nebulizer followed by non-invasive positive pressure ventilation. He began to recover and we again used the HighFO nebulizer during the weaning period. Case 2: A 74-year-old man presented with acute exacerbation of interstitial pneumonitis. We started steroid pulse therapy, HighFO nebulizer treatment and physiotherapy to prevent disuse syndrome. We were able to raise his exercise stress levels due to the high concentration of oxygen provided by the HighFO nebulizer. We believe that the HighFO nebulizer is useful for type-I respiratory failure as well as interstitial pneumonia. However, oxygen toxicity is a potential problem, so we must accumulate more cases in order to fully assess the risks and benefits of this new modality.

RESUMEN

BACKGROUND: To investigate the relationship between the prognosis of chronic interstitial pneumonia (IP) and its comorbidities, we conducted a retrospective study for clinically and radiologically diagnosed IP. We assessed comorbidities by using the Charlson Comorbidity Index (CCI). METHODS: We classified 224 patients given clinical diagnoses of chronic IP (excluding the patients who had clear causes such as collagen disease, infection, drugs or radiation) in our institution between April 2000 and June 2010, into 2 groups; those with clinical diagnoses of idiopathic pulmonary fibrosis (IPF:108 cases) and those with other chronic IP but without honeycomb lung (116 cases); and analyzed their backgrounds and comorbidities. We also classified them into survival and non-survival groups to assess their prognostic factors. RESULTS: Although the smoking status of patients with clinically diagnosed IPF was higher, and SpO2 was lower than those with other chronic IP without honeycomb lung, the mean age, comorbidities and CCI did not differ between them. The 5-year overall survival of the clinically-diagnosed IPF group was lower than that of the other chronic IP without honeycomb lung group (50.8% vs. 76.3%, p<0.01). In cases of other chronic IP without honeycomb lung, the CCI of non-survival cases was higher than that of survival cases (4.05 vs. 2.47, p<0.01), although patient backgrounds did not differ between survival and non-survival cases in those with clinically diagnosed IPF (CCI : 2.32 vs. 2.98, p = 0.70). CONCLUSIONS: Our analysis revealed the possibility that comorbidities and CCI were prognostic factors in other chronic IP cases without honeycomb lung, although the prognosis of IPF was not affected by their comorbidity.

RESUMEN

A 64-year old male who had been treated with oral predisolone for severe bronchial asthma had started the treatment of omalizumab administration every 4 weeks since December 2009 and his symptoms had prominently improved. However, he complained the recurrence of his symptoms 4 weeks after administration of omalizumab and the mean times of SABA use had also increased from 0.61/day (1-2w) to 0.95/day (4w). Therefore, we had shortened the interval of omalizumab to 3 from 4 weeks since April 2010. Consequently, his symptoms have improved with increase of Asthma Control Test (15.67→21.33) and it has been possible to reduce the oral prednisolone. Recently, we can use the omalizumab and have extended the choice of treatment for severe bronchial asthma. However, it is predicted that there are some patients who have clinical problems for continuing the recommendation dose or intervals. We report a case with a brief review of the literature.

RESUMEN

BACKGROUND: Although pleurodesis is an effective treatment for malignant pleural effusion, we hesitate to use in patients with poor performance status (PS) because of its side effects. METHODS: Of 46 pleurodesis cases in our institution between 2006 and 2010, 24 poor PS cases (>3) were classified into 2 groups according to survival (beyond 3 months) or non-survival, and 3 groups according to condition: PS improved after pleurodesis, remained stable, or was exacerbated and we analyzed their backgrounds. RESULTS: Among the 24 cases (66.7%), there were 5 and 19 survival and non-survival cases. Patient backgrounds, characteristics of the lesions and examination results did not differ significantly among them. On the other hand, the ratio of successful initial pleurodesis in the exacerbated PS group was lower than in the improved and stable groups (16.7% vs. 100%, 87.5%). The 1- and 3-month survival rates of unsuccessful cases were lower than those of successful cases (33.3% vs. 77.8%, 0% vs. 32.4%). CONCLUSION: Success of initial pleurodesis can affect PS and outcome, thus it is important to improve the number of successful cases of initial pleurodesis.

RESUMEN

BACKGROUND: Lung abscess, although curable when caught early and treated appropriately, still may recur repeatedly or require surgery. We retrospectively assessed prognostic lung abscess factors and predictive recurrence factors. We evaluated comorbidity using the Charson comorbidity index (CCI). METHODS: Subjects numbered 44 hospitalized for lung abscesses between June 2004 and May 2009 and classified as; elderly (over 65 years) or non-elderly and cured treatment failed. RESULTS: Mean age and the CCI of failed treatment were statistically higher than in cures at 80.8 years and 3.25 vs 64.1 years and 1.25 (p < 0.05). Abscess location, smoking habits, symptoms, white blood cell count and C-reactive protein did not differ on day 1. The causative organism, fistula presence at 65.6% vs 45.5% (p = 0.30) and lesion size at 59.8 mm vs 71.6 mm (p = 0.14) did not differ between groups, but the degree of lesion size reduction in treatment failures was lower than cures at 24.9% vs 69.1% (p < 0.05). CONCLUSIONS: Lung abscess prognosis is thus adversely affected by age and comorbidity. In Japan, subjects having multiple comorbidities are expected to increase with aging. The degree of lesion size reduction appears to be a predictive factor in recurrence, underscoring the importance of follow-up in imaging, including chest computed tomography.

RESUMEN

A 64-year old hospitalized male for severe bronchial asthma began to complain fatigue and appetite loss. His asthma had been treated with oral bethamethasone. The Chest CT at this time revealed a bilateral consolidation of the lower lung. Despite a week of treatment with antibiotics and anti-fungals, the patient expired from DIC progression. His premortem sputum and blood culture grew Cryptococcus Neoformans. We concluded his diagnosis as cryptococcal pneumonia and sepsis. Sepsis by Cryptococcus neoformans is a rare clinical event, and only 20 cases have been reported in Japan. Although 16 of the 20 had preexisting medical conditions, a case with underlying bronchial asthma has never been reported. A comparison of the reported cases of the US and Europe to that of Japan revealed differences in the patients' underlying conditions. We report a case with a brief review of the literature and summarize the 20 cases that have been reported in Japan.
