ABSTRACT
Objective:To analyze the clinical characteristics and risk factors for mortality of severe pneumocystis carinii pneumonia(PCP)in pediatric liver transplant(LT)recipients.Methods:The data of severe PCP in LT recipients diagnosed at Shanghai Children′s Medical Center from November 2019 to February 2021 were collected.The clinical characteristics and risk factors for 28-day mortality were analyzed.Results:Fifteen patients were enrolled in the study.Thirteen cases survived and 2 cases were non-survived.There was no routine anti-pneumocystis prophylaxis after LT.The median age of onset of PCP was 12(7, 26)months.The median time after LT was 3.00(0.33, 4.00)months.The onset clustered in November-December and June-August.All patients were mechanically ventilated, and some patients were given prone ventilation(11 cases), neuromuscular blocking agents(13 cases)and high concentration oxygen(more than 60%, nine cases). Fourteen cases were complicated with other infections.Two cases were complicated with pneumothorax and subcutaneous/mediastinal emphysema.There were 2 cases with septic shock-like manifestation, 1 case of right heart insufficiency, 1 case of right heart failure(death), and 1 case of multiple organ failure(death). Compared with the survived group, the non-survived group had higher pediatric risk of mortality Ⅲ score[3.5(0.0, 6.0)vs.8.5(5.0, 12.0), Z=1.993, P=0.046] and lactate dehydrogenase level[1 731.5(1 012.0, 3 270.0)U/L vs.4 387.5(3 606.0, 5 169.0)U/L, Z=2.148, P=0.032]. Conclusion:PCP in pediatric LT is critical and complicated.Pediatric risk of mortality Ⅲ scores and lactate dehydrogenase increase in 28-day hospitalized deaths.
ABSTRACT
Objective:To investigate the clinical characteristics and prognosis factors in children with pneumocystis carinii pneumonia (PCP) without human immunodeficiency virus (HIV) infected.Methods:From January 2017 to December 2020, 35 non-HIV infected patients with PCP were admitted to Hunan Children′s Hospital.According to the prognosis at discharge, they were divided into survival group and death group.The clinical characteristics of two groups were compared, and the prognostic factors were analyzed.Results:The age of 35 patients ranged from 1 month to 15 years, including 24 males and 11 females.Seven patients(20.0%) had primary immunodeficiency, 5 patients(14.2%) had autoimmune disease, and 4 patients(11.4%) had renal disease.Eighteen patients were treated with long-term hormone and 13 patients were treated with immunosuppressive agents before the onset of the disease.Clinical symptoms included shortness of breath or dyspnea, cough, fever and so on, while with few pulmonary signs.Peripheral blood lymphocyte count was less than 1.5×10 9/L in 18 cases.The median LDH was(654.94±57.66)U/L; Fungal D-glucan increased in 13 cases.The median P/F was(121.29±23.25)mmHg, and P/F was less than 200 mmHg in 16 cases.CD4 cells were less than 500/μL in 15 cases and less than 200/μL in 8 cases.The imaging findings were mainly consolidation or patellar shadow, diffuse ground glass shadow, 3 cases with pleural effusion, and 1 case with pneumothorax.Twenty-two cases survived and 13 died, with a mortality rate of 37.1%.There were statistically significant differences in hospitalization days, CD4 cell count, Fungal D-glucan, P/F, ICU admission and invasive mechanical ventilation between two groups( P<0.05). Logistic multivariate analysis showed that decreased P/F value was an independent risk factor affecting the prognosis of non-HIV infected children with PCP ( OR=0.006, 95% CI 0.975-1.000). Conclusion:The clinical manifestations, laboratory examinations and imaging examinations of non-HIV infected patients with PCP lack specificity.When a diagnosis is suspected, high-resolution CT should be performed based on the results of peripheral blood lymphocyte count, CD4 cell count, fungal D, LDH, and blood gas analysis results as soon as possible, compound sulfamethoxazole should be used timely.Decreased P/F value is an independent factor affecting the prognosis of non-HIV children with PCP.

ABSTRACT
Objective:To explore the clinical characteristics of pneumocystis carinii pneumonia (PCP) after kidney transplantation.Methods:From January 2020 to January 2022, clinical data were retrospectively reviewed for 13 renal transplant recipients with pneumocystis pneumonia diagnosed by metagenomics next generation sequencing (mNGS). There were 3 females and 10 males with an age range of (46±10) years.The median time of postoperative onset was 10(2-21) months; The major clinical manifestations included fever ( n=11), cough ( n=7), expectoration ( n=6) and dyspnea ( n=11). Paired t-test was employed for analyzing the laboratory results at admission and discharge. Results:The diagnosis was confirmed by the detection of NGS in alveolar lavage fluid or venous blood.The levels of G test, LDH test, total T lymphocyte absolute count (CD3+ Abs), inhibitory/cytotoxic T lymphocyte count (CD3+ CD8+ Abs) and auxiliary/induced T lymphocyte absolute count (CD3+ CD4+ Abs) were (543.27±440.49) pg/ml, (529.98±222.43)U/L and (191.92±119.42)/μl, (87.33±50.59)/μl and (106.92±87.42)/μl at admission and (69.58±50.21) pg/ml, (285.38±46.62 U/L), (888.58±672.99)/μl, (336.83±305.21)/μl and (520.08±388.76)/μl at discharge.The differences were statistically significant ( P<0.001, P=0.002, 0.006, 0.017, 0.005). All of them received compound sulfamethoxazole and caspofungin.Except for one death due to septic shock after 21-day treatment, 12 cases were cured. Conclusions:mNGS test is one of the important tool for an early diagnosis of PCP.Combined use of compound sulfamethoxazole and caspofungin is an effective anti-infective regimen.And immune function monitoring is vital for adjusting antibiotic and immunosuppressive regimens.
ABSTRACT
Objective:To explore the nursing points of pneumocystis carinii pneumonia after liver transplantation in infants.Methods:Strengthened artificial airway management for children to improve dyspnea. Adopted nasal high-flow humidifying oxygen therapy to correct hypoxemia. Implemented individual temperature management to effectively control high fever. Strengthened children′s medication management, predictive skin management, using the protective isolation and psychological nursing.Results:After timely treatment and careful nursing, the condition of the three children was improved, SpO 2 was maintained at 0.95-1.00, and the patients were discharged successfully. One patient with respiratory failure died of multiple organ failure due to the deterioration of the condition after receiving extracorporeal membrane oxygen and supportive treatment. Conclusions:The infants with pneumocystis carinii pneumonia after liver transplantation should strengthen airway management, correct hypoxia. At the same time to do a good job of symptomatic care, strengthen the observation of the condition, can promote the rehabilitation.
ABSTRACT
Pneumocystis Carinii Pneumonia (PCP) and Pulmonary Tuberculosis (PTB) are the most frequent Opportunistic Infection (OI) in People living with HIV/AIDS (PLWHA), especially whose CD4 counts<200 cells/mL. There is no pathognomonic sign and symptom of pneumocystis, radiographic imaging (chest radiograph) and blood examination. An intractable microorganism cannot be isolated or sustained in culture. The diagnosis of PCP is complicated, based on the presumptive diagnosis. PCP should be treated optimally as soon as possible in order not to be fatal. We report a complicated case of a female 26 y-old, diagnosed with HIV infection on Highly Active Anti Retro Viral Therapy (HAART), PTB on Anti Tuberculosis Drugs (ATD) concurrent with PCP. She also has a history of various Drug Hypersensitivity Reactions (DHR) include Rifampycin, Ciprofloxacin and Cotrimoxazole. DHR is unpredictable, and Clindamycin and Primaquin are the recommended alternative drugs for PCP, the strategic therapy is by Desensitization Protocols.

ABSTRACT
OBJECTIVE:To explore the method and role of clinical pharmacists in pharmaceutical care for nephrotic syndrome complicated with Pneumocystis carinii pneumonia (PCP). METHODS:Clinical pharmacists participated in the treatment for a pa-tient with nephrotic syndrome complicated with PCP,and implemented pharmaceutical care in terms of the development of anti-in-fective therapy regimens,glucocorticoid optimization,guardianship for drug use,the medication education for patients. Clinical pharmacists provided suggestion that primary anti-infective plan of azithromycin 0.5 g,ivgtt,qd+Compound sulfalene tablet 2 tab-lets,po,q12 h;which was not effective,was adjusted plan as Compound sulfalene tablet 3 tablets,po,q6 h+clindamycin 0.6 g, ivgtt,q8 h+caspofungin 50 mg,ivgtt,qd. The dose of Methylprednisolone for injection was adjusted 4 times according to disease progression. RESULTS:Physicians adopted the suggestions of clinical pharmacists. After 30 days of treatment, lung abnormal le-sion was absorbed basically and infection control was achieved. CONCLUSIONS:Clinical pharmacists participate in anti-infective treatment and pharmaceutical care,and assist physicians to develop therapy plan to promote rational drug use in the clinic and im-prove the effectiveness and safety of clinical treatment.
ABSTRACT
Objective To analyze the epidemiologic characteristics and risk factors for mortality in non-(human immunodeficiency virus,HIV) infected children with pneumocystis carinii pneumonia(PCP). Methods The data of non-HIV infected children with PCP diagnosed in Beijing Children′s Hospital from January 1,2006 to December 31,2012 were collected. They were divided into survival and non-survival group according to the prognosis. The epidemiologic characteristics and risk factors for mortality were analyzed. Results Sixteen patients were enrolled in this study. Ten of them survived and 6 of them were non-survived. The basic diseases included malignant tumor in 5 patients and non-malignancy diseases in 11 of them. Com-pared with the survival group,the non-survival group had a higher average age [(12. 00 ± 2. 00) years vs. (6. 65 ± 4. 32)years,P=0. 01],higher ratio to need mechanical ventilation (6/6 vs. 4/10,P=0. 04),lower PaO2/FiO2[(73. 88 ±26. 95) mmHg vs. (167. 50 ± 97. 17) mmHg,1 mmHg=0. 133 kPa,P=0. 01] and lower pediatric critical illness score(75. 67 ± 5. 72 vs. 86. 40 ± 8. 88,P=0. 02). There were no differences on sex ratio,kinds of basic diseases,whether with co-infections,the time of immunosuppressant administration, the time from onset to diagnosis,the time from onset to beginning trimethoprim-sulfamethoxazole therapy, PaCO2 ,white blood cell counts,lymphocyte counts,CD4+ cell counts,C-reactive protein,and hemoglobin con-centrations between the survival and non-survival group. Conclusion A higher age, need for mechanical ventilation,lower PaO2/FiO2 and lower pediatric critical illness score were risk factors for mortality in non-HIV infected children with PCP.
ABSTRACT
Objective To explore the diagnosis,treatment and nursing of the patients complicated with pneumocystis carinii pneumonia (PCP) after renal transplantation,and to enhance the treatment effect of the disease.Methods The treatment and nursing processes of 37 patients complicated with PCP after renal transplantation in department of organ transplantation were retrospectively analyzed in the First Affiliated Hospital of China Medical University from May 1992 to July 2011.And the key points during nursing work were summarized.Results Of the total 37 patients,10 patients occurred respiratory failure,they were all treated by noninvasive ventilation,among which 6 patients were converted to tracheal intubation or tracheotomy mechanical ventilation.5 patients appeared rising serum creatinine(Scr) during treatment,but recovered to normal level after discontinuing SMZco for 1 week.4 patients died unfortunately,and the others were cured and discharged.Conclusions The occurrence of PCP after renal transplantation is closely related to the immune state of the patients,thus the priority of treatment for PCP should be prevention.Once happened,nursing care in aid is particularly important,then nurses should encourage patients to cooperate with treatment,relieve symptoms after infection,and promote recovery as well.
ABSTRACT
Pneumocystis carinii pneumonia (PCP) has rarely been reported in solid tumor patients. It is a well-known complication in immunosuppressed states including acquired immune deficiency syndrome and hematologic malignancy. PCP has been reported in solid tumor patients who received long-term steroid treatment due to brain or spinal cord metastases. We found 3 gastric cancer patients with PCP, who received only dexamethasone as an antiemetic during chemotherapy. The duration and cumulative dose of dexamethasone used in each patient was 384 mg/48 days, 588 mg/69 days, and 360 mg/42 days, respectively. These cases highlight that the PCP in gastric cancer patients can successfully be managed through clinical suspicion and prompt treatment. The cumulative dose and duration of dexamethasone used in these cases can be basic data for risk of PCP development in gastric cancer patients during chemotherapy.

ABSTRACT
Pneumocystis carinii pneumonia (PCP) is an infectious disease of immune-compromised host. Sometimes it is difficult to differentiate PCP with diffuse pulmonary hemorrhage. Association between PCP and diffuse pulmonary hemorrhage has been reported in 30% of PCP with HIV positive patients. But association between PCP and diffuse pulmonary hemorrhage has not been reported in non-HIV positive patients without any known underlying causes of diffuse pulmonary hemorrhage. We report a case of PCP with diffuse pulmonary hemorrhage in 66 years old male patient. We confirmed PCP and diffuse pulmonary hemorrhage with bronchoalveolar lavage. We can exclude the possible other causes of diffuse pulmonary hemorrhage except PCP. PCP may be one of possible cause of diffuse pulmonary hemorrhage in non-HIV immune compromised patient.

Pneumocystis carinii pneumonia (PCP) is one of the most common causes of infection in patients with HIV infection. With the development of effective prophylactic agent, the incidence of PCP in patients with HIV infection has been declining. On the other hand, however, the incidence of PCP has been increasing in immunocompromised hosts without HIV infection, such as rheumatoid arthritis, bone marrow transplantaion and Behcet syndrome. The increased occurrence of PCP in non-HIV- infected subjects has been attributed to several factors, such as use of stronger immunosuppressive regimens, higher awareness of PCP, advanced diagnostic technology and nosocomial spread of P. carinii. The occurrence of PCP in patients who receive immunosuppressive drugs for autoimmune disease has not been well known in Korea. We report a patient with Behcet syndrome who suffered from PCP after immunosuppressive drugs.

BACKGROUND: Pneumocystis carinii pneumonia (PCP) is one of the most common cause of infection in patients with HIV infection. Recently, the incidence of PCP have been increasing in immunocompromised hosts without HIV infection. We compared the clinical characteristics of PCP between HIV infected and non-infected persons. PATIENTS AND METHODS: We retrospectively reviewed the charts of 25 patients diagnosed as PCP from 1996 to 2002. Age, sex, underlying conditions, use of immunosuppressants, clinical courses, laboratory findings, treatment and prognosis were compared between HIV infected and non-infected persons. RESULTS: Twenty-five patients with PCP were identified. 16 were HIV infected, and 9 were HIV non-infected. The mean age of overall patients was 43.4+/-13.2 years. Underlying conditions in HIV non-infected persons were hematologic malignancy (7 cases), solid organ transplant (1 case), and autoimmune disease (1 case). Seven cases (77.8%) of HIV non-infected persons had a history of steroid use. Mean duration of symptoms was longer in HIV infected persons than in HIV non-infected persons, but it was not statistically significant. PaO2 was lower in HIV infected persons (61.2+/-16.9 mmHg vs.65.4+/-15.4), but it was not statistically significant. Chest X ray showed typical ground glass opacity in 12 cases (75%) of HIV infected persons and in 4 cases (44.4%) of HIV non-infected persons. Twelve cases (75%) of HIV infected persons were treated with steroid, as were 6 cases (66.7%) of HIV non-infected persons. Ventilator care was needed in 6 cases (37.5%) of HIV infected persons and in 2 cases (22.2%) of HIV non-infected persons. Mortality of HIV infected persons was 50%, and that of HIV non-infected persons was 11.1%. CONCLUSIONS: PCP showed some different clinical characteristics between HIV infected and non-infected persons. Prospective studies regarding the risk factors of PCP, prophylaxis, treatment and prognosis in HIV infected and non-infected persons are warranted.

Objective To investigate the clinical diagnosis and treatment of pneumocystis carinii pneumonia(PCP) after kidney transplantation. Methods Eight patients who developed PCP between 90 days and 140 days following renal transplantation were enrolled in this study.All of them were male with a mean age of 28 years.The clinical manifestations,accessory examinations and treatment were retrospectively analyzed. Results All the 8 patients fully recovered.With early diagnosis and administration of compound sulfamethoxazole(SMZ),clinical symptoms of 6 patients were rapidly controlled within 5 to 7 days.Because of delayed diagnosis and treatment,the conditions of the other 2 cases were more severe and were controlled within 25 days and 46 days separately. Conclusions Application of percutaneous pneumocentesis biopsy can be useful for correct diagnosis in early stage of PCP and has high positive rate of the pathogen. Most PCP patients can be cured with early use of SMZ.Types and doses of immunosuppressor should be adjusted properly.
