Objective To investigate the feasibility and methods of surgical treatment for HIV/AIDS patients with otolaryngology diseases. Methods From January 2016 to February 2017, nineteen patients with HIV/AIDS who underwent otolaryngology surgery were included in this study. The demographic data of patients, including age, gender, course of disease, CD4+ T lymphocyte count before operation and disease type were collected and the clinical treatment methods were summarized. The curative effect was analyzed retrospectively. Results The operations of all the 19 patients were successful without occupational exposure among medical staff. One patient with papillary squamous cell carcinoma did not received further treatment. The other 18 patients recovered well and their life quality was significantly improved. Conclusions If HIV/AIDS patients with otolaryngological diseases are examined preoperatively and have no surgical contraindications, the operation shloud be performed by controlling the surgical indications strictly. The life quality of the patients may be improved and the patients’ life may be prolonged after the surgery.
Objective To evaluate the relation of human immunodeficiency virus (HIV)-1 ribonucleic acid (RNA) loads in cerebrospinal fluid with central neurological diseases. Methods The inpatients with HIV-1 infection diagnosed by Public Health Clinical Center of Chengdu between January 1st, 2015 and March 1st, 2018 were retrospectively included. The included patients were divided into central neurological disease group and non-central neurological disease group, and high viral load group and low viral load group. The demographic data, CD4+ T lymphocyte count, routine detection of cerebrospinal fluid, HIV RNA load in cerebrospinal fluid and plasma of patients with and without central neurological diseases were observed and compared.Multiple logistic regression analysis was used to identify risk factors for central neurological diseases. Results A total of 367 patients were included. In the central neurological disease group, 210 cases (57.22%) were complicated with central neurological diseases, and cryptococcus infection was the most. Compared with the non-central neurological disease group, the increase rate of cerebrospinal fluid cell counts, cerebrospinal fluid cell counts, cerebrospinal fluid HIV RNA positivity and cerebrospinal fluid HIV RNA load were higher in the central neurological disease group (P<0.05). Logistic regression analysis showed that HIV RNA load in cerebrospinal fluid≥100 000 copies/mL and CD4+ T lymphocyte count<200 cells/mm3 were risk factors for central neurological diseases. Conclusion Cerebrospinal fluid HIV RNA load≥100 000 copies/mL is an independent risk factor for HIV/AIDS patients with central neurological diseases and clinical treatment should take this factor into consideration to reasonably optimize the selection of antiretroviral therapy.
ObjectiveTo evaluate the clinical significance of human immunodeficiency virus (HIV) testing algorithm combining antigen/antibody assay screening with Western Blot (WB) or HIV nucleic acid.MethodsData of HIV antigen and antibody screening samples in West China Hospital of Sichuan University in 2018 were retrospectively analyzed. The 4th generation antigen and antibody reagents were used for initial screening, and the 3rd generation antibody reagents were used for reexamination. WB or HIV nucleic acid detection was performed as supplementary test.ResultsA total of 217 803 samples were initially screened, 718 samples were positive in initial screening (0.33%) and 513 samples were confirmed positive (0.24%). The 718 initial positive samples were confirmed by WB, among them, 513 (71.45%) were positive, 163 (22.70%) were negative, and 42 (5.85%) were indeterminate. Fifteen samples which were negative or indeterminate were detected by HIV RNA, as a result, 6 were positive. Two of four patients turned into positive during follow-up. Among the 536 samples which were positive in both the 4th and 3rd generation assay, there were 513 (95.71%) positive, 6 (1.12%) negative, and 17 (3.17%) indeterminate confirmed by WB; among the 182 samples which were positive in the 4th generation assay but negative in the 3rd generation assay, there were none (0.00%) positive, 157 (86.26%) negative, and 25 (13.74%) indeterminate confirmed by WB. The positive rate of confirmation test of samples positive in the 4th and 3rd generation assay (95.71%, 513/536) was significantly higher than that of samples positive in the 4th generation assay but negative in the 3rd generation assay (0%, 0/182), and the difference was statistically significant (χ2=610.091, P<0.001). WB band types for positive samples were dominated by the whole bands and sub-bands, accounting for 82.26%. The cut off index in ≥5 bands group was higher than that in < 4 bands group (P<0.001).ConclusionsSamples with both the 4th and 3rd generation assay positive have a high positive rate of confirmation test, and a supplementary test is needed to be done as soon as possible to confirm the diagnosis. Samples with only the 4th generation assay positive have a low positive rate of confirmation test. But for patients with a high-risk history, HIV nucleic acid should be done as soon as possible for early diagnosis.
ObjectiveTo compare the value of CURB-65 score and expanded CURB-65 score in evaluating prognosis of pneumonia in non-HIV infected patient and HIV infected patient.MethodsThe study included 206 hospitalized pneumonia patients without HIV infection and 299 pneumonia patients with HIV infection. According to their clinical prognosis within 4 weeks of treatment, they were divided into a deterioration group and an improvement group. The basic situation and the differences of clinical indicators between the two groups were compared. The predictive value of CURB-65 score and expanded CURB-65 score for clinical prognosis of pneumonia in non-HIV infected patients and HIV infected patients was compared by using receiver operator characteristic (ROC) curve.ResultsFor the pneumonia patients without HIV infection, the area under ROC curve (AUC) of CURB-65 score and expanded CURB-65 score were 0.862 and 0.848, respectively. There was no significant difference in AUC between CURB-65 score and expanded CURB-65 score (Z=0.661, P=0.5084). The Youden indexes of CURB-65 score and expanded CURB-65 score were 60.11% and 54.92%, respectively. For the pneumonia patients with HIV infection, the AUC of CURB-65 score and expanded CURB-65 score were 0.588 and 0.634, respectively. There was no significant difference between them (Z=1.416, P=0.1567). The Youden index of the two scores was 19.53% and 20.52%, respectively.ConclusionsThe CURB-65 score and expanded CURB-65 score can effectively evaluate the clinical prognosis of pneumonia in non-HIV infected patients, but their predicted values are limited in evaluating the prognosis of pneumonia in HIV infected patients.
Human immunodeficiency virus (HIV) infection mainly attacks the human immune system, causing a variety of opportunistic infections and tumors, among which neoplastic diseases are serious and life-threatening. In recent years, with the popularization of highly effective anti-retroviral virus, the disease spectrum of HIV infected people has changed greatly, the incidence of non-acquired immune deficiency syndrome (AIDS) related tumors has increased significantly, and the diagnosis rate of esophageal cancer patients with HIV/AIDS has also increased. However, there is no consensus on how to standardize the diagnosis and treatment of esophageal cancer patients with HIV/AIDS. This article reviews the epidemiological characteristics, diagnosis and treatment of esophageal cancer patients with HIV/AIDS.
Objective To analyze the clinical data of monkeypox (mpox) cases in Chengdu, to investigate the clinical characteristics of patients with mpox complicated with human immunodeficiency virus (HIV) / acquired immunodeficiency syndrome (AIDS), and provide reference for clinical diagnosis and treatment. Methods Mpox patients admitted to Public Health Clinical Center of Chengdu between June 29 and August 8, 2023 were continuously included. Patients were divided into an observation group and a control group based on whether they were complicated with HIV/AIDS. The clinical characteristics of two groups of patients were observed and compared. Results A total of 56 patients were included, all of whom were male; Age range from 19 to 51 years old, with an average of (31.6±5.9) years old; There were 23 cases in the observation group and 33 cases in the control group. Except for age, perianal lesions with infection, number of rashes, diarrhea, CD4+ lymphocyte count, CD4/CD8 ratio, syphilis, chest CT abnormalities, rash duration, and length of hospital stay (P<0.05), there was no statistically significant difference in epidemiological data, clinical features, auxiliary examinations, treatment, and intensive care unit admission between the two groups of patients (P>0.05). There was a statistically significant difference between the Ct values of throat swab nucleic acid and blister fluid nucleic acid in the total population [(30.1±4.4) vs. (23.4±3.8); t=5.462, P<0.001]. Conclusions Mpox patients complicated with HIV/AIDS are prone to persistent, diverse, and severe lesions due to relatively lower CD4+ lymphocyte counts. Therefore, it is necessary to actively provide symptomatic treatment and prevent complications for patients.
