RESUMEN

Kaposi varicelliform eruption (KVE) is a cutaneous dissemination of a viral infection, which is mostly caused by herpes simplex virus (HSV) in the setting of certain underlying skin diseases. KVE occurs mainly in infants and children, but very rarely in adults. Here, we report a case of KVE with contact dermatitis in a 36-year-old man with acquired immunodeficiency syndrome (AIDS), who was referred to our deparment with pruritic well-defined facial erythema and multiple vesicular lesions. A punch biopsy and immunohistochemical examination established the diagnosis of KVE with contact dermatitis. After treatment with valacyclovir and antihistamines, facial lesions achieved complete remission. With this case report, KVE has specific manifestation in clinic, histopathology and immunohistochemistry, which could guide the early diagnosis and improve prognosis.

RESUMEN

Serofast status after therapy in syphilis patients is a common phenomenon. A proportion of patients who have serofast status exhibit abnormal cerebrospinal fluid test results, which can be defined as asymptomatic neurosyphilis (ANS); however, it remains unclear whether ANS patients can achieve serological cure after anti-neurosyphilis treatment as quickly as other serofast patients. In this study, non-treponemal pallidum antibody serological responses were studied in ANS and serofast control patients, and the cumulative rates of serological cure in the ANS group were 9.6, 22.1, 25.9, and 30.2% in 3, 6, 9, and 12 month after treatment, which were statistically higher than those of the serofast control group. The change gap in serological cure rates was even more pronounced within 6 months after treatment, but the majority of ANS patients had no change in serofast status at 12 months after treatment. Our study indicates that anti-neurosyphilis therapy can partially change the serofast status. As serofast status cannot easily be changed even under neurosyphilis treatment in the majority of patients, the pathogenesis of this condition needs further research.

RESUMEN

BACKGROUND: Albuvirtide is a once-weekly injectable human immunodeficiency virus (HIV)-1 fusion inhibitor. We present interim data for a phase 3 trial assessing the safety and efficacy of albuvirtide plus lopinavir-ritonavir in HIV-1-infected adults already treated with antiretroviral drugs. METHODS: We carried out a 48-week, randomized, controlled, open-label non-inferiority trial at 12 sites in China. Adults on the World Health Organization (WHO)-recommended first-line treatment for >6 months with a plasma viral load >1000 copies/mL were enrolled and randomly assigned (1:1) to receive albuvirtide (once weekly) plus ritonavir-boosted lopinavir (ABT group) or the WHO-recommended second-line treatment (NRTI group). The primary endpoint was the proportion of patients with a plasma viral load below 50 copies/mL at 48 weeks. Non-inferiority was prespecified with a margin of 12%. RESULTS: At the time of analysis, week 24 data were available for 83 and 92 patients, and week 48 data were available for 46 and 50 patients in the albuvirtide and NRTI groups, respectively. At 48 weeks, 80.4% of patients in the ABT group and 66.0% of those in the NRTI group had HIV-1 RNA levels below 50 copies/mL, meeting the criteria for non-inferiority. For the per-protocol population, the superiority of albuvirtide over NRTI was demonstrated. The frequency of grade 3 to 4 adverse events was similar in the two groups; the most common adverse events were diarrhea, upper respiratory tract infections, and grade 3 to 4 increases in triglyceride concentration. Renal function was significantly more impaired at 12 weeks in the patients of the NRTI group who received tenofovir disoproxil fumarate than in those of the ABT group. CONCLUSIONS: The TALENT study is the first phase 3 trial of an injectable long-acting HIV drug. This interim analysis indicates that once-weekly albuvirtide in combination with ritonavir-boosted lopinavir is well tolerated and non-inferior to the WHO-recommended second-line regimen in patients with first-line treatment failure.

RESUMEN

BACKGROUND: Although clinical manifestations of symptomatic and asymptomatic neurosyphilis are different, few laboratory tests could reflect the difference. METHODS: A total of 92 non-HIV-infected patients with syphilis were enrolled in this study, including 23 with symptomatic neurosyphilis, 51 with asymptomatic neurosyphilis, and 18 with latent syphilis, which were excluded neurosyphilis because they were found to have no symptom and normal cerebrospinal fluid (CSF) tests and served as the control group. The concentrations of neurofilament light subunit (NF-L) and phosphorylated neurofilament heavy subunit (pNF-H) in the CSF were measured and compared among these groups, as well as before and after treatment in the symptomatic and asymptomatic groups. RESULTS: The median concentrations of NF-L in the symptomatic neurosyphilis, asymptomatic neurosyphilis, and control groups were 5806, 218, and 266 pg/mL, respectively (P < 0.001), and the median concentrations of pNF-H were 986, 43, and 49 pg/mL, respectively (P < 0.001). A subgroup of 15 symptomatic neurosyphilis and 10 asymptomatic neurosyphilis patients were followed up and underwent CSF examination 6 months after the antineurosyphilis treatment. The median concentration of NF-L in the symptomatic neurosyphilis group decreased from baseline 6420 to 2914 pg/mL after the treatment (P = 0.03), and the median concentration of pNF-H in the symptomatic neurosyphilis group decreased from baseline 1399 to 246 pg/mL after the treatment (P = 0.03). CONCLUSIONS: Neurofilament light subunit and pNF-H were significantly elevated in the symptomatic neurosyphilis patients, not in asymptomatic neurosyphilis, which was an implication of the different pathogeneses in neurosyphilis.

RESUMEN

Here we reported a Chinese case of bilateral peripheral facial paralysis (PFP) in human immunodeficiency virusc (HIV) infected population. A 38-year-old homosexual male patient was referred to our hospital for bilateral facial paralysis. 21 days prior to admission he had developed high fever, chills, headache, fatigue, general malaise, nausea and vomiting. Neurological examination revealed bilateral ptosis of lower lip and cheeks, as well as failure of bilateral eyes closure. Analysis of cerebrospinal fluid (CSF) revealed pleocytosis, a marked rise of micro total protein and a marked rise of intrathecal lgG synthesis. The result of HIV-1 serology was positive by ELISA and that was confirmed by western blot. His CD4 + cell count was 180 cells/mm 3. HIV-1 viral load in CSF was almost 10 times higher than that in plasma. The patient's condition improved steadily and experienced complete resolution of bilateral PFP after 2 months.

RESUMEN

More new diagnosed syphilis cases were reported in china, the incidence and relevant factors of asymptomatic neurosyphilis (ANS) in serofast syphilis patients were unclear. Clinical and laboratory data of 402 Human Immunodeficiency Virus (HIV) negative, serofast syphilis patients, who underwent lumbar puncture at the Peking University Ditan Teaching Hospital between September 2008 and August 2016, were collected. Incidence of ANS was verified and the relevant factors were further analyzed. According to the ANS criteria, 139 (34.6%) patients had ANS. Of these, 40 (28.8%) had reactive cerebrospinal fluid (CSF), rapid plasma reagin (RPR) positive, 115 (82.7%) had CSF white blood cell (WBC) count > 5 × 106/L, 28 (20.1%) had CSF protein concentration > 45 mg/dL (without other neurological diseases). Patients aged 51-60 years, of non-Han ethnicity, with serum RPR titer 1:32 and ≥ 1:64 were 2.28-fold, 9.11-fold, 5.12-fold and 5.69-fold, respectively, more likely to have ANS. The incidence of ANS was 34.6% among Chinese serofast syphilis patients. Age, ethnicity and serum RPR titer were associated with high risk of ANS.

RESUMEN

OBJECTIVE: Study on quality of life of asymptomatic HIV infected persons with traditional Chinese medical, which can provide the clinical basis for improving the quality of life. METHOD: This study applied a randomized, double-blind, and placeb-parallel control designed method to select 1 200 persons in the asymptomatic period of HIV infection as the subjects. The subjects were randomly divided into the treatment group and the control group at the ratio of about 2:1. According to the results of monthly differential diagnosis of TCM, the test group and the control group were given homologue Chinese drugs preparations and model Chinese drugs. The total study period was 18 months. Using PRO scale and the world health organization AIDS determination of quality of life short scale form (WHOQOL-HIV-BREF) to investigate asymptomatic HIV infected persons, according to different times, we calculated the total score and each domain score of quality of life of the treatment group and control group, we did statistical analysis. RESULT: Form the PRO scale,we can see that the treatment group showed a trend of stability, compared with the control group with significant statistical difference (P < 0.05) after 6 months; from the WHOQOL-HIV scale analysis, we can see that compared with before treatment, the quality of life of the treatment group was increased, the difference was significant (P < 0.05), but the quality of life of the control quality of life was decreased, the differences was significant (P < 0.05). CONCLUSION: Dialectical therapy of Chinese medicine can significantly improve the patient's quality of life, which can provide the basis for the prevention and control policy formulation and implementation with asymptomatic HIV infected persons.

RESUMEN

OBJECTIVE: Analyzing the relationships between peripheral blood CD4+ CD25hi regulatory T (Treg) cells and peripheral blood immune status or plasma HIV-lviral load in HIV-infected individuals,so as to determine whether Treg were related to the progression of HIV-infected disease. METHODS: 116 HIV-infected patients in different stages and 21 healthy control individuals were included in this study. The CD4+ and CD8+ T cell counts were determined by a standard 4-color flow cytometry technique. The Treg cells were examined with 3-color immune staining flow cytometry. The plasma HIV-1 viral load was detected by real time PCR. RESULTS: The frequencies of Treg cells decreased in HIV-infected individuals with high CD4+ T cell counts( > 300/microl) compared with normal controls. With the progression of disease the frequencies of Treg cells were raised gradually, until were increased in HIV-infected individuals with low levels of CD4+ T cell counts ( < 100/microl). In addition, the frequencies of Treg cells were inversely related to CD4+ T cell counts and CD4+ /CD8+ ratio, data showed a statistically significant (respectively, r = -0.564, P < 0.001; r = -0.377, P < 0.001). Furthermore, the proportions of Treg cells were closely related to plasma HIV-1 RNA viral load (r = 0.514, P < 0.001). CONCLUSION: CD4 CD25hi Treg cells should be a kind of important cells participating the immunopathogenesis of AIDS. It may play different roles in different stages of HIV-infected disease. The exact mechanism of Treg cells in the progression of the HIV-infected disease needs to be investigate further.

RESUMEN

OBJECTIVE: To understand the correlation between CD4+ cell count, HIV viral load (VL) and clinical characteristics among patients when HIV-1 was tested positive and initial AIDS diagnosis was made. METHODS: 690 HIV-infected cases from Beijing Di-Tan Hospital were included and under a cross sectional study while SPSS statistical method was used. RESULTS: The 690 HIV-infected cases would include 458 males and 232 females with age range from 2-72 years (mean age as 35.3). The modes of transmission showed that: homosexual contact taking up 17.5% while heterosexual was 16.7%. Most of the homosexual-infected ones lived in Beijing and most of them had bachelor or master's degrees. 19.4% of the transmission happened between heterosexual/bisexual couples, suggesting that HIV was transmitted through the "bridge population" while the rest were infected by contaminated blood/plasma. Many of the cases were identified when they lately visited the pre-operation surveillance point in the hospital. Serious immunodeficiency symptoms or signs were discovered as: CD4+ count < 50 cell/microl, serious opportunistic infections including pneumocystosis pulmonary, cerebral toxoplasmosis and cryptococcal meningitis. Higher frequencies of diseases seen were dermotosis, pneumonia, upper respiratory tract infection, hepatitis and digestive tract moniliasis. CONCLUSION: Because of the late identification of the disease, serious immuo-suppression situation often appeared, suggesting that there was an urgent need to improve STD/AIDS knowledge on those HIV (+) people so they might have an early access to accept medical care.

RESUMEN

Virus-specific cellular immune responses play an important role in the control of immunodeficiency virus replication. However, preclinical trials of vaccines that induce virus-specific cellular immune responses have failed to contain simian immunodeficiency virus (SIV) replication in macaques. A defective provirus DNA vaccine system that efficiently induces virus-specific CD8(+) T-cell responses has previously been developed. The vaccinated macaques showed reduced viral loads, but failed to contain SIVmac239 replication. In this study, macaques that showed partial control of SIV replication were followed up to see if or how they lost this control in the chronic phase. Two of them showed increased viral loads about 4 or 8 months after challenge and finally developed AIDS. Analysis of SIV-specific T-cell levels by detection of SIV-specific gamma interferon (IFN-gamma) production revealed that these two macaques maintained SIV-specific CD8(+) T cells, even after loss of control, but lost SIV-specific CD4(+) T cells when plasma viral loads increased. The remaining macaque kept viral loads at low levels and maintained SIV-specific CD4(+) T cells, as well as CD8(+) T cells, for more than 3 years. Additional analysis using macaques vaccinated with a Gag-expressing Sendai virus vector also found loss of viraemia control, with loss of SIV-specific CD4(+) T cells in the chronic phase of SIV infection. Thus, SIV-specific CD4(+) T cells that were able to produce IFN-gamma in response to SIV antigens were preserved by the vaccine-based partial control of primary SIV replication, but were lost with abrogation of control in the chronic phase.
