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 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

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

@#Objective To study the alteration of surfactant protein A and D(sp-A,SP-D)result-ing from pneumcystis carinil pneumonia(PCP)and investigate its implication in the pathogenesis of PCP.Methods SD rat models of PCP were induced by subcutaneous injection of 25 mg cortisone acetate,normal control and negative control as well as bacterial pneumonia group were set up for comparison.During 8~12weeks.broncboalveolar lavage fluid (BALF) of rats was collected.Total nucleate cells of BALF were counted and differentiated as well as the concentrations of surfactant protein A(SP-A)and surfactant pro-tein D(SP-D)were measured by immunoblotting assay.Results The rats were divided into three im-munosuppressive groups,plus a norrflal control group. Group A: normal control(n=6)consisted of healthy SD rats;group B:negative control(n=6)employed rats with cortisone acetate injection over 8weekz without tung infection;group C:bacterial pneumonia(n=11),rats were injected with cortisone ac-etate over 8 weeks and resulted in bacterial pneumonia without other pathogens isolated;group D(n=14):rats were injected with cortisone acetate during 8~12 weeks and resulted in PCP without other pathogens isolated.During PCP infection,the total cell counts and the percentage of polymorphonuclears (PMNs)in BALF were significantly increased(P<0.01),but were lower than those in the bacterial pneumonia group.The concentration of SP-A of BALF in PCP(45.1 μg/ml 4±22.1 μg/m1)was signifi-cantly increased in comparison with that in negative control group(16.2 μg/ml±9.9 gg/ml,P<0.05)and that in bacterial pneumonia group(6.2 μg/ml±5.6 μg/ml,P<0.001).We also found that the rela-tive content of SP-D was significantly higher in PCP(24 249±4 780 grey values)than that in both nega-tive control(13 384±2 887 grey values,P<0.001)and bacterial pneumonia group(11 989±2 750 grey values,P<0.001).SP-A and SP-D were also higher in moderate to severe group of PCP than those seen in mild group(P<0.01,P<0.001).Conclusion There was obvious increase of SP-A and SP-D in PCP rats,and particularly,the change of which was greater than that in bacterial pneumonia.Therefore,the alteration of SP-A and SP-D may be of implication in the prevention and management of PCP.

ABSTRACT

Renal allograft recipients are at risk for Pneumocystis carinii pneumonia (PCP) within the first year following transplantation and during treatment for graft rejection. We experienced two cases of PCP in renal allograft recipients. The first case was a 39-year-old female who had received renal allograft 7 years before. At the time of traosplantation, she was a carrier of hepatitis B surface (HBs) antigen. After transplantation, she had been received the rnaintenance dose of cyclosporine and oral prednisolone. Three months before adrnission, dosage of prednisolone was increased because of the increased serum creatinine level and gene-ralized edema. A week before admission, syrnptom of exertional dyspnea, dry cough, and fever was developed. Chest X-ray film showed streaky interstitial infiltration in both lung fields and chest CT showed diffuse ground-glass appearance. Rroncho- alveolar lavage revealed positive Grocott's methenamine silver stain for numerous clumps of pneumocystis carinii cysts. Despite the aggressive treatment, she died of respiratory and hepatic failure and GI bleeding. Another case was a 40-year-old male who had received renal allograft S years before. He had been received maintenance immune suppressive therapy with cyclosporine and oral prednisolone. He was admitted for evaluation of hypertension and elevated serum creatinine level. After several days of admission, he complained fever, dry cough and dyspnea. X-ray film showed pneumonic infiltration and the bronchial brushing and washing fluid revealed the Pneumocystis carinii cysts that were stained by methenamine silver. He was treated with the full dose of trimethoprim-sulfamethoxazole and clindamycin. Sacrificing the renal allograft, he recovered from Pneumocystis carinii pneumonia.

ABSTRACT

Pneumocystis carinii is the most common cause of diffuse pulmonary infiltrates in the immunocompromised patients. Microscopically, Pneumocystis carinii pneumonia(PCP) shows characteristic frothy intraalveolar exudate and interstitial lymphocytic and plasma cell infiltrate. However, sometimes the only histologic finding of PCP on routine hematoxylin-eosin stain is that of diffuse alveolar damage(DAD), when we can miss the diagnosis without aid of special stains. We report a case of Pneumocystis carinii pneumonia presenting as DAD in a 50-year old man after chemotherapy due to malignant lymphoma. Open lung biopsy specimen reveals the early stage of DAD without any characteristic findings, such as foamy exudate. However many cysts of Pneumocystis carinii were found on Gomori's methenamine silver(GMS) stain. Therefore, GMS stain should be routinely performed on all biopsy specimens obtained from immunocompromised patients.

ABSTRACT

The human lower respiratory system begins to form about day 26-27 after conception, and is first indicated by a median larngotracheal groove in the caudal and of the ventral wall of the larynx, trachea, bronchi and the pulmonary lining epithelium. The connective tissue, the cartilage and the smooth muscle of these structures develop from the splanchnic mesoderm surrounding the foregut. In studying the development of the respiratory system at the Department of Anatomy, Siriraj Hospital, Medical students should trace the serial section of 10 mm and 15 mm pig embryos. In doing this, they be able to observe the layngotracheal groove at the floor of the pharynx and when, tracing the sections caudally, they will be able to observe the trachea, esophagus and the bifurcation of the trachea to from primary bronchi as well as the smaller branches of bronchi. The present study attempts to show the development of the respiratory system of rat embryos in order to find the most suitable stage which can be used as a laboratory model for use by students. A 6 mm rat embryo can be used instead of a pig embryo for studying the development of the respiratory system, if pig embryos are not available.

ABSTRACT

Authors report the first autopsy case of acquired immune deficiency syndrome in Korea. The patient was a 26 years old Korean male who died of respiratory failure due to mixed pulmonary infections. He had history of homosexual contacts with partners of both domestic and foreign nationalities. Initial presentation was unexplained fever for two months. Serological test and western blot test for anti-HIV were positive and T-cell subset analysis revealed T3/T4/T8 to be 73/8/67%. Pulmonary tuberculosis with mediastinal lymphadenopathy and esophagonadal fistula and oral candidiasis were presented. Respiratory infection progressed gradually and he died seven months after the initial symptom. Autopsy findings were generalized severe lymphoid cell depletion, especially of T-cell population and mixed pulmonary infections with Pneumocystis carinii and cytomegalovirus (CMV). The CMV infection involved lungs and adrenals. Oral candidiasis was also demonstrated.

ABSTRACT

Objective:To study the Pathological changes in lungs of rats infected with Pneumocystis carinii pneumonia after treatment with bilodalide(BL). Methods:PCP rat models were established of hypodermic injection of dexamethasone twice a week for 6 weeks. The PCP rats were treated with BL 30mg/(kg.d)?8days and killed to obtain lungs. Pathological changes in lung tissues were observed under light and electron microscope .Infected and normal rats were established as controls. Results: The number of Pc cysts was markedly reduced in the lung print smear and inflammation in the lung was lightened. The investigation of thinner lung tissue section by transmission electronic microscope showed that the Pneumocystis carinii treated with bilobalide had formation of vacuoles in trophozoites,swelling and destroying of cell organ, rupture of cytomembrane and some high density electronic granulae were investigated in the cytoplasm. Membrane of cyst was destroyed too. Conclusion:Bilodalide can kill Pc and alleviate inflammation in the lung tissues of PCP rats.
