Objective To investigate the clinical characters of death in AIDS patients with Penicilliosis marneffei (PSM), improving the diagnosis and treatment of PSM. Methods Retrospectively analyze the data of 27 AIDS patients died of PSM from January 2009 to December 2011 and review the relevant literatures in the past several years. Results The etiology diagnosis time ranged from 4 to 7 (4.9 ± 1.4) days from admission. There were 22 (81.5%) cases complicated with septic shock and 25 (92.6%) cases complicated with metabolic acidosis. There were 12 (44.4%) cases co-infected with pneumocyst pneumonia , 7 (25.9%) cases with TB. The main reasons accounting for the death were as follow:15(55.6%) cases died of septic shock, 5(18.5%) cases died of respiratory failure. Conclusion The death cases of AIDS patients with PSM showed the characters of relatively late etiology diagnosis and pathogenic therapy , mostly complicated with other opportunistic infections and often died of septic shock. Therefore, timely etiology diagnosis and earlier pathogenic therapy are the keys to treat the disease. Effectively controlling of the complications and co-infections may decrease the mortality.

Objective To study the pathogens and drug resistance profiles of pulmonary infection in patients with AIDS. Methods The pathogens and their drug susceptibility of pulmonary infection diagnosed by fibrobronchescopy-induced brunchoalveolar lavage fluid (BAI.F) culture and/or transbronchial biopsy in 116 AIDS cases were analyzed. Results Monopathogenic infection in lungs were detected in 18 cases(15.5%) and mixed infection in 98 cases ( 84.5%). Of the 116 cases, bacteria were present in 91 patients, fungi in 62, tubercle bacillus in 49, pneumocystis jiroveci in 29, and cytomegalovirus in 11.Ninety-five bacterial strains were isolated from BALF, mainly including Streptococci (34), coagulase negative Staphylococcus (20), Klebsiella pneumoniae (10) and Escherichia (7). The isolated bacteria were resistant to β-lactam, macrolides, quinolones and aminoglycosides, of which were 14 methicillin-resistant Streptococci (MRS) strains and 12 extended spectrum β-lactamases (ESBL) strains. Sixty-eight fungal strains were isolated, including 36 Candida mycodermas, 19 Penicilliums, 6 Aspergilli and 5 Mold fungi;they were sensitive to amphotericin B but resistant to fluconazol (5.6% -50. 0% ) and itraconazole( 10. 5%-60. 0% ). Conclusion Pneumonia in AIDS patients are usually caused by multiple pathogens,predominantly consisting of multiresistant bacteria and fungi. Therefore, antibiotics should be rationally chosen according to drug susceptibility test.

Objective To explore the pathogen spectrum, drug resistance rate and clinical characteristics of pneumonia caused by non-tuberculous mycobacteria (NTM) in acquined immuno-deficiency syndrome (AIDS) patients.Methods The clinical data of 31 hospitalized AIDS patients with bronchoalceolar lavage flind (BALF) culture confirmed NTM pulmonary disease in Guangzhou No.8 People′s Hospital from January,2008 to February,2015 were retrospectively analyzed, including pathogen spectrum, drug resistance rate and clinical characteristics.The clinical characteristics and drug resistance were compared between Mycobacterium avmm-intracellulare complex (MAC) pneumonia and the non-MAC pneumonia, and t test and chi-square test were used.Results Of the 31 AIDS patients,28 were male and 3 were female, with the mean age of 40.9 years old.The 31 NTM strains were consisted of 14 MAC strains and 17 non-MAC strains (including 4 M.kansasii strains,3 M.lentiflavumstrains, 2 M.szulgai strains, 2 M.yongonense strains etc).There was no significant difference between two groups in sex ratio, mean age, clinical manifestations, laboratory tests and treatment outcome (all P>0.05).The major clinical manifestations included fever, productive cough, weight loss, anemia and low CD4+ count (<50/μL).Most patients showed thoracic lymphadenectasis and patchy shadows in lungs, and few patients had millet shadows and pericardial effusion.Compared with non-MAC strains, MAC strains had higher drug resistant rate of moxifloxacin (10/14 vs 4/17), levofloxacin (14/14 vs 8/17), and clarithromycin (11/14 vs 7/17).More extensively drug resistance strains were seen in non-MAC strains compared with MAC strains (11/14 vs 7/17).Conclusions MAC is the most common pathogen of NTM pulmonary disease in AIDS patients.The clinical features of pneumonia caused by MAC and non-MAC are similar, but drug resistance of MAC strains are more severe.

Objective To analyze the characteristics of opportunistic infection (OI) in patients with HIV/AIDS in Guangdong and the relationship between OI and the change in blood CD4+ T lymphocyte count (CD4+ ).Methods Seven hundred and sixty two patients with HIV/AIDS admitted were analyzed. Results Among all the 762 patients, 704 (92.39% ) had more than one kind of OI, with 1428 episodes totally.Etiologically, fungus infection (38.38% ) was most common, followed by bacteria (36.20% ), and virus (7.77% ) infection. Most OI occurred in the lungs (33.05% ), mouth (26.89% ), skin (10.29% ) and gastro-intestine (8.96% ).Septicemia and other systemic disseminated diseases accounted for 6.58% and 9.94% respectively.The incidence of OI in patients with CD4+= 200/μ1 (103/136, 75.74%) was significantly lower than that in patients with CD4+ <200/μ1 (601/626, 96.01%), P<0.01.All the AIDS defining OI were found in patients with CD4+ <200/μ1 Among them, 81.97% of patients with pneumonia carinii pneumonia (PCP), 71.43% of patients with cytomegalovirus retinitis and all the patients with cryptococcal meningitis, disseminated cryptococosis, disseminated histoplasmosis, mycobacterium avium intracellular complex (MAC), disseminated penicilliosis mameffei and toxoplasma cerebritis had the CD4+ less than 50/ μ1.Conclusions The most common OI in patients with AIDS in Guangdong area are fungi, bacterial and viral infections.Lung, mouth, skin, gastro-intestine and systemic disseminated infections are the most prevalent infections.As the CD4+ decreased, the incidence of OI especially AIDS defining OI increased. Dynamic detection of CD4+ will be of great help for the prediction, prevention, early diagnosis and treatment of OI in patients with AIDS.

ObjectiveTo investigate the pathogens and prognostic factors of AIDS-associated severe pneumonia. MethodsClinical data were collected from 95 patients with AIDS-associated severe pneumonia admitted to Guangzhou No. 8 People' s Hospital from January 2005 to December 2008. The pathogens of pulmonary infections were investigated. Univariate analysis and multivariate logistic regression analysis were performed to study the relationships between the outcome and influencing factors. Results The most prevalent pathogen was Pneumocystis jirovecii (64/95, 67.4％ ), followed by bacteria (61/95, 64.2％ ),fungi ( 50/95, 52. 6％ ), mycobacterium tuberculosis ( 27/95, 28. 4％ ) and cytomegalovirus ( CMV ) (25/95, 26.3％ ). Among 95 cases, monocontamination was detected in 15 cases ( 15.8％ ), while mixed infection in 80 cases (84. 2％ ). Logistic regression analysis showed that mechanical ventilation, higher serum lactic dehydrogenase (LDH) level and severe underlying diseases were risk factors for the death of AIDS-associated severe pneumonia, and higher serum albumin level was the protective factor. Conclusion Pneumocystis jirovecii, bacteria and fungi are the main pathogens for AIDS-associated severe pneumonia, and mixed infection is popular.

Objective To investigate the clinical features, prognosis and risk factors of patients of acquired immunodeficiency syndrome (AIDS) complicated with cryptococcal meningitis (CM). Methods Totally 26 patients of AIDS with CM who were hospitalized in the No. 8th People's Hospital of Guangzhou were enrolled in this study. The clinical data including diagnosis,experimental and etiological test,treatments and prognosis from all the patients were analyzed retrospectively. The results of cerebrospinal fluid routine test and CD4+ T lymphocyte were compared with those of AIDS patients complicated with tuberculous meningitis. Results Among the 26 patients enrolled in the study, the positive rate of cerebrospinal fluid india ink smear or Crypotococcus neoforrnans euhure was 84.6%. The most common symptoms were fever, headache and meningeal irritation sign. The average CD4+ lymphocyte count was 17.83 × 106/L, which was statistically different from that of tuberculous meningitis patients. All the patients showed concomitant multiple organ infections. The mortality rate was as high as 42.3%. At the end of therapy, the cell counts in the eerebrospinal fluid were remarkably higher in the patients with unfavorable prognosis compared to the patients with good prognosis, which was statistically different. Conclusions CD4+ lymphocyte count is an important marker for differentiating CM from tuberculous meningitis in AIDS patients. The results of cerebrospinal fluid routine test can predict the prognosis.

Objective To explore the risk factors for the prognosis of acquired immunodeficiency syndrome (AIDS)-related lymphoma (ARL).Methods A total of 32 patients with ARL were enrolled in this study from Guangzhou Eighth People's Hospital during August 2011 and July 2014,who were followed up for 2 to 48 months (median 9 months).The risk factors for the prognosis of ARL were analyzed by Logistic regression analysis.Results A total of 32 patients were included,among whom 27 were males and the rest were females,with a mean age of (42.8± 13.5) years (ranging from 4 to 70 years).Regarding the clinical staging at the initial diagnosis,6 cases (18.8 ％) were classified as stage Ⅰ,4 cases (12.5％) stage Ⅱ,5 cases (15.6％) stage Ⅲ,and 17 cases (53.1％) stage Ⅳ.As for international prognostic index (IPI) score,4 cases (12.5％) were in the low risk group (IPI 0-1),5 cases (15.6％) in the low-middle group (IPI 2),8 cases (25.0％) in the middle-high risk group (IPI 3),and 15 cases (46.9 ％) in the high risk group (IPI 4-5).According to the pathological diagnosis,26 cases (81.2％) were B cell non-Hodgkin lymphoma (NHL),4 cases (12.5％) were T cell NHL,and 2 cases (6.2％) were Hodgkin lymphoma (HL) nodular sclerosis.In total,23 cases (71.9％) had received highly active antiretroviral therapy (HAART) before the first hospital visit or within one month after the diagnosis of lymphoma.Sixteen (50.0％) cases received standard chemotherapy regimen formulated by the oncology specialists.A total of 17 patients died,with the mortality rate of 53.1％.By univariate analysis,the prognostic factors included age (OR=0.915,P=0.012),high lactate dehydrogenase (OR=1.006,P=0.021) value at baseline,receiving HAART (OR =12.444,P=0.011),and standard chemotherapy regimen (OR=13.000,P=0.001).By multivariate Logistic regression,receiving standard chemotherapy regimen (OR=0.035,P=0.022) was the only prognostic factor of ARL.Conclusions The mortality of ARL is high and the most common pathological type was NHL.The prognosis could be improved by standard chemotherapy regimen on the basis of HAART.

Objective:To analyze the clinical features of acquired immunodeficiency syndrome (AIDS) patients complicated with peripulmonary occupational lesions.Methods:Fifty-five AIDS patients with peripulmonary occupational lesions treated in Guangzhou Eighth People′s Hospital from January 2012 to January 2019 were included, and the clinical data of patients were retrospectively analyzed. According to the results of lung biopsy, the patients were divided into Mycobacterium infection group, fungal infection group and tumor group. The clinical characteristics, the proportion of different CD4 + T lymphocyte counts and chest computed tomography (CT) features of the three groups were compared. Chi square test was used for comparison among the three groups, and Bonferroni method was used to correct the test level for pairwise comparison. The significance level was 0.016 7 because of three pairwise comparisons. Results:Among 55 AIDS patients complicated with peripulmonary occupational lesions, pulmonary biopsy showed 14 cases with Mycobacterium infection, 12 cases with fungal infection and 15 cases with tumor lesions. Mixed diseases were found in 11 patients, including seven cases with Mycobacterium and fungus coinfection, four with tumor complicated with fungus and (or) Mycobacterium. Three with chronic interstitial pneumonia. The main clinical manifestations of 55 patients were fever, expectoration, fatigue, weight loss and superficial lymph node enlargement. There were no significant differences in symptoms/signs, white blood cell counts, hemoglobin levels, alanine transaminase and creatinine among Mycobacterium infection group, fungal infection group and tumor group (all P>0.05). There was significant difference in anti-retroviral therapy (ART) acceptance among the three groups ( χ2=15.165, P<0.01). However, the results of pairwise comparison between groups showed that there was significant difference between fungal infection group and tumor group ( χ2=7.514, P<0.016 7), while there was no significant difference between Mycobacterium infection group and tumor group, Mycobacterium infection group and fungal infection group ( χ2=0.255 and 5.306, respectively, both P>0.016 7). There were significant differences in clinical outcomes among the three groups ( χ2=15.119, P<0.01), and the pairwise comparison between the Mycobacterium infection group and the tumor group, and the fungal infection group and the tumor group showed significant differences ( χ2 =10.311 and 9.095, respectively, both P<0.016 7). The cases with CD4 + T lymphocyte count ≤50/μL, 51-<200/μL and ≥200/μL in Mycobacterium infection group were three cases, one case and 10 cases, respectively; those in fungal infection group were 10 cases, two cases and 0 case, respectively, and those in tumor group were one case, two cases and 12 cases, respectively. The difference was statistically significant ( χ2=21.284, P<0.01). Chest CT showed that there was significant difference in the types of space occupying lesions among the three groups ( χ2=13.308, P=0.003), and pairwise comparison between the two groups showed that there was significant difference between the Mycobacterium infection group and the tumor group ( χ2=11.312, P<0.016 7), while there were no significant differences between the Mycobacterium infection group and fungal infection group ( χ2=0.931, P>0.016 7), and the fungal infection group and the tumor group ( χ2=7.053, P>0.016 7). There was significant difference among the three groups in calcification focus ( χ2=8.524, P=0.004), while there was no difference between the Mycobacterium infection group and fungal infection+ tumor group ( χ2=10.982, P<0.016 7). Conclusions:Mycobacterium infection, fungal infection and tumor are the main types of peripulmonary occupational lesions in AIDS patients. The differential diagnosis could be made by combining with chest CT features, ART acceptance and CD4 + T lymphocyte level.

Objective To evaluate the therapeutic effect of highly active anti-retroviral therapy (HAART) in treatment-na(i)ve Chinese patients with AIDS, to provide evidences for standardizing HAART.Methods Seventy-four treatment-naive AIDS patients were initiated with HAART and followed up regularly for 3 years. The clinical and laboratory data, side effects and drug resistance were observed and analyzed during the follow-up period. Results Of the 74 patients, 46 were males and 28 were females, with the average age being 42 years. The mean HIV viral load was ( 2. 2 ± 2.0 ) × 105 copies/ml and the baseline mean CD4+ T lymphocyte count was (62 ± 71 )cells/μl before treatment. After treatment for 3, 6, 12, 18,24, 30 and 36 months, the percentage of undetectable HIV viral road (less than 50 copies/ml ) was 71.6%, 83.8%, 75.7%, 77.0%, 82.4%, 81.1% and 79.7% respectively, and CD4+T lymphocyte count ascended to ( 167 ± 105), ( 177 ± 129), (238 ± 137), (290 ± 158), (304 ± 191 ), (331 ± 175) and ( 352 ± 202 ) cells/μl. The increase in amplitude of CD4+ T lymphocyte count in different periods examined was different, with the period of 0-3 months post-treatment demonstrating the most obvious augmentation ( P ＜ 0. 01 ) . The most common adverse reactions were liver function injury ( 52/74,70. 3% ), hyperlipemia (52/74, 70. 3%), hematopoietic inhibition of the bone marrow (33/74, 44. 6% ),peripheral neuritis (32/74, 43.2% ) and lipoatrophy (26/74, 35. 1%). Clinical drug resistance were found in nine patients and HIV gene mutations were detected in these patients. Conclusions Chinese treatment-naive AIDS patients have achieved good virological and immunological response to generic-drugpredominant HAART regimes with low drug resistance, but relatively more side effects.
