Psychosocial characteristics pattern correlated with HIV-related risky sexual behavior among HIV-negative men who have sex with men: a latent profile analysis

BACKGROUND@#Men who have sex with men (MSM) have become a high risk population of HIV infection due to their risky sexual behaviors. The latent pattern of psychosocial characteristics plays an important effect in HIV-related risky behaviors among HIV-negative MSM.@*METHOD@#Participants were recruited from Wuhan, Nanchang, and Changsha city from September 2017 to January 2018. Social support was assessed by the multidimensional scale of social support, Connor-Davidson Resilience scale-10 items for reliance, the assessment of Stigma towards Homosexuality for sexual minority stigma, the Likert subscale of nondisclosure for identity concealment, the ACE questionnaire-Kaiser-CDC for adverse childhood experience, the Centers for Epidemiological Studies Depression Scale for depression. Latent profile analysis (LPA) and multivariate regression were used to analyze the data.@*RESULTS@#Three psychosocial characteristic patterns were revealed by the LPA. "Social support and resilience group" (SR group), "Identity concealment group" (IC group) and "Adverse childhood experience" (ACE group) were identified, respectively. In comparison with "SR group", "IC group" have a higher likelihood of one-night male partners (AOR = 2.74, 95%CI = [1.54, 4.90]), both fixed and one-night male partners (AOR = 2.01, 95%CI = [1.34, 3.01]) and HIV-unsure male partner (AOR = 2.12, 95%CI = [1.44, 3.13]). Similarly, "ACE group" were more likely having inconsistent condom use (AOR = 2.58, 95%CI = [1.41, 4.73]), and having sex with HIV-positive male partner (AOR = 4.90, 95%CI = [1.95, 12.30]) with comparison of "SR group". In addition, we further revealed that "ACE group" had a higher ratio (90.0%) of inconsistent condom use among MSM whose male partners were HIV-positive.@*CONCLUSIONS@#Six important psychosocial factors were divided into three latent pattern classes. Compared with "SR group", "IC group" and "ACE group" were more likely to engage in HIV-related risky sexual behaviors. Further research may pay more attention to "IC group" and "ACE group" for targeted intervention.

HIV-negative plasmablastic lymphoma: report of 8 cases and a comprehensive review of 394 published cases

BACKGROUND: Human immunodeficiency virus (HIV)-negative plasmablastic lymphoma (PBL) is a rare entity of diffuse large B-cell lymphoma (DLBCL). The clinicopathological features of and optimal treatment for HIV-negative PBL remain largely unknown.METHODS: To gain insight into this distinct lymphoma, we summarized the clinicopathologic characteristics of 8 unpublished HIV-negative PBLs and performed a comprehensive review of 394 published cases.RESULTS: Of the 8 unpublished PBLs, the median patient age was 53.0 years. Four patients presented with stage IV disease. All 8 patients showed a plasma cell-like immunophenotype. Of the six patients who received anthracycline-based chemotherapy, including two who received bortezomib, three patients achieved a continuous complete response, two patients died due to disease progression, and one patient was lost to follow-up. The other two patients achieved continuous complete response after receiving chemotherapy combined with radiotherapy and surgery. Of the 402 patients, the majority were male, with a mean age of 58.0 years. EBV infection was detected in 55.7% of the patients. The median survival times of the patients who received CHOP or CHOP-like regimens and intensive regimens were not reached and 23.0 months, respectively, and the intensive regimen did not improve the survival outcome (P=0.981). Multivariate analysis showed that EBER remained the only independent factor affecting overall survival (OS).CONCLUSION: HIV-negative PBL is a distinct entity with a predilection for elderly and immunosuppressed individuals. Intensive chemotherapy had no apparent survival benefits over the CHOP regimen in terms of OS; the prognosis of this disease is poor with current chemotherapy methods, and treatment remains a challenge.

Criptococosis vertebral: comunicación de un caso y revisión bibliográfica / Vertebral cryptococosis: case report and literature review

Resumen La criptococosis es una micosis sistémica producida por un hongo levaduriforme encapsulado denominado Cryptococcus neoformans. Es una enfermedad universal, que ocurre con mayor frecuencia en pacientes inmunocomprometidos, manifestándose principalmente como una enfermedad diseminada con compromiso meníngeo o pulmonar. Sin embargo, la osteomielitis ocurre solo en 5-10% de los casos, siendo el compromiso vertebral el más frecuente. Presentamos un caso de criptococosis vertebral aislada y una búsqueda bibliográfica sobre el tema. Se recomienda realizar una terapia antifúngica de inducción intravenosa y continuar con una fase de consolidación, vía oral, de duración variable. La indicación quirúrgica se considera en lesiones que comprometen la estabilidad vertebral y aquellas que presentan un compromiso neurológico, producen deformidad y para reducir el inóculo infeccioso.

Cryptococcosis is an infectious disease caused by a ubiquitous encapsulated yeast called Cryptococcus neoformans, it is usually associated with immunosuppressed patients. Osteomyelitis occurs in 5-10%, the spine involvement is one of the most reported. The purpose of this work is to present a case of isolated vertebral cryptococcosis and detail the results of a literature review. The treatment protocol is not yet established but it is recommended to start with aggressive intravenous therapy and continue with a suppressive treatment orally during a variable time. Surgical indication is considered in lesions that affect the spinal stability, deformity or neurological compromise and for local infectious control.

Cutaneous Kaposi Sarcoma of a Non-HIV Infected Patient in Korea.

Aims: We present this case to report clinical knowledge about unusual feature of classic Kaposi sarcoma in Korea. Presentation of Case: We report on a case involving an unusual clinical feature of a 76- year-old HIV-seronegative, HHV-8 infected Korean male, which was histologically confirmed as cutaneous Kaposi sarcoma (KS) on the ankle and foot dorsum. Discussion: KS is an intermediate-grade angioproliferative neoplasm derived from lymphatic endothelium in association with AIDS and human herpes virus 8 (HHV-8) infections. The tumor does not commonly affect non-HIV infected persons. Development of the disease occurs through the complicated interplay of HHV-8 with genetic, immunologic, and environmental factors. We discuss several risk factors presenting in most patients but were not observed in this patient, who did not fit easily into any of the well-known subtypes. Conclusion: Diagnosis of KS is often not possible solely on the basis of morphological characteristics. Based on our review of the literature, this is a sporadic case of classic KS according to its unusual clinical features.

Cerebral Syphilitic Gumma Mimicking a Brain Tumor in the Relapse of Secondary Syphilis in a Human Immunodeficiency Virus-Negative Patient

Diagnosis of cerebral syphilitic gumma is frequently determined at the time of surgery, because imaging and laboratory findings demonstrate the elusive results. A 59-year-old woman presenting dysarthria showed a mass on her brain computed tomography. She was first suspected of brain tumor, but histological results from surgical resection revealed cerebral gumma due to neurosyphilis. After operation, she presented fever and rash with an infiltration on a chest X-ray. Histological assessment of skin was consistent with syphilis. Fluorescent treponemal antibody absorbed test IgG in cerebrospinal fluid was positive. She was successfully treated with ceftriaxone for 14 days.

Pulmonary cryptococcosis in non-AIDS patients

OBJECTIVE: To investigate the clinical features, management, and prognosis of pulmonary cryptococcosis in non-acquired immunodeficiency syndrome (AIDS) patients. METHOD: 24 cases of pulmonary cryptococcosis with accurate pathological diagnosis were retrospectively studied. RESULTS: 15 male patients and nine female patients were diagnosed at the first affiliated hospital of Sun Yat-sen University from November 1999 to November 2011. The mean age at the time of diagnosis was 44.2 ± 11.3 years (range: 24 to 65 years). Among these patients, 13 had other comorbidities. 15 were symptomatic and the other nine were asymptomatic. The most common presenting symptoms were cough, chest tightness, expectoration, and fever. None had concurrent cryptococcal meningitis. The most frequent radiologic abnormalities on chest computed tomography (CT) scans were solitary or multiple pulmonary nodules, and masses or consolidations, and most lesions were located in the lower lobes. All patients had biopsies for the accurate diagnosis. Among the 24 patients, nine patients underwent surgical resections (eight had pneumonectomy via thoracotomy and one had a pneumonectomy via thoracoscopy). Five of the patients who underwent surgery also received antifungal drug therapy (fluconazole) for one to three months after the surgery. The other 15 only received antifungal drug therapy (fluconazole or voriconazole) for three to six months (five patients are still on therapy). The follow-up observation of 19 patients who had already finished their treatments lasted from two to 11 years, and there was no relapse, dissemination, or death in any of these patients. CONCLUSION: Non-AIDS patients with pulmonary cryptococcosis have a good prognosis with appropriate management.

Profound CD4+ T lymphocytopenia in human immunodeficiency virus negative individuals, improved with anti-human herpes virus treatment / Linfocitopenia T CD4+ grave, en individuos negativos para virus de immunodeficiencia humana, mejoró con tratamiento antivirus herpes humanos

Lymphocytopenia and CD4+ T lymphocytopenia can be associated with many bacterial, fungal, parasite and viral infections. They can also be found in autoimmune and neoplastic diseases, common variable immunodeficiency syndrome, physical, psychological and traumatic stress, malnutrition and immunosuppressive therapy. Besides, they can also be brought into relation, without a known cause, with idiopathic CD4+ T lymphocytopenia. Among viral infections, the Retrovirus, specially the human immunodeficiency virus, is the most frequently cause. However, many acute viral infections, including cytomegalovirus and Epstein Barr virus can be associated with transient lymphocytopenia and CD4+ T lymphocytopenia. As is well known, transient lymphocytopenia and CD4+ T lymphocytopenia are temporary and overcome when the disease improves. Nonetheless, severe CD4+ T Lymphocytopenia associated with chronic infections by human herpes virus has not been reported. We describe 6 cases of human immunodeficiency virus negative patients, with chronic cytomegalovirus and Epstein Barr virus infections and profound lymphocytopenia with clinical symptoms of cellular immunodeficiency. These patients improved rapidly with ganciclovir or valganciclovir treatment. We claim here that it is important to consider the chronic human herpes virus infection in the differential diagnosis of profoundly CD4+ T lymphocytopenia etiology, when human immunodeficiency virus is absent, in order to start effective treatment and to determine, in future studies, the impact of chronic human herpes virus infection in human beings' health.

Múltiples enfermedades bacterianas, micóticas, parasitarias y virales pueden asociarse con linfocitopenia y linfocitopenia CD4+. También enfermedades autoinmunes, neoplásicas, inmunodeficiencia común variable, estrés físico, sicológico o traumático, la malnutrición y el tratamiento con inmunosupresores. Esta condición también se presenta sin causa aparente y es conocida como linfocitopenia T CD4+ idiopática. Entre las infecciones virales, los retrovirus, especialmente el virus de inmunodeficiencia humana, es la más frecuente causa, pero muchas otras infecciones virales agudas, entre ellas, la mononucleosis por citomegalovirus y por Epstein Barr virus, se asocian con linfocitopenia total y linfocitopenia T CD4+, que son transitorias y se recuperan cuando la enfermedad mejora. Una linfocitopenia grave asociada con infección crónica por virus herpes humanos y que mejore con el tratamiento de ellos, no ha sido publicada. Se describen 6 pacientes, negativos para virus de inmunodeficiencia humana, con linfocitopenia total y linfocitopenia T CD4+ graves y con manifestaciones clínicas de inmunodeficiencia celular, quienes respondieron rápidamente al tratamiento con ganciclovir o valganciclovir. Es importante considerar la infección crónica por virus herpes humanos en el diagnóstico diferencial de la etiología de la linfocitopenia T CD4+ en individuos no infectados por el virus de inmunodeficiencia humana, para iniciar un tratamiento efectivo de los pacientes y determinar en futuros estudios el impacto de la infección crónica por herpes virus en la salud humana.

Cryptococcal liver abscess in HIV-negative individual.

Opportunistic fungal infections in immunocompromised patients are usually caused by candida, aspergillus, cryptococcus or zygomycetes. Rarely, fungal infections may occur in immunocompetent indivivals and are usually caused by cryptococcus or aspergillus. When infected by cryptococcus, the usual sites of infection include respiratory tract, central nervous system, or skin. Uncommon sites are liver, spleen, prostate, and bone marrow. When it involves liver, it can present with micro-abscesses, cholangitis, or hepatitis. Here we report a case of cryptococcal infection of liver in a HIV-negative patient presenting with micro-abscesses.

HIV-negative plasmablastic lymphoma: A report of two cases and review of literature / 解放军医学杂志

Objective To investigate the origin, diagnosis, differential diagnosis, treatment, and prognosis of plasmablastic lymphoma (PBL). Methods Based on the retrospective analysis of the clinical data of two patients with PBL admitted to our department from 2009 to 2010, followed by a review of related literatures in China and abroad, we summarized our experience of the diagnosis and treatment of PBL. Results Two patients as reported in this paper were explicitly diagnosed to be HIV negative (-): one presented enlarged lymph nodes, whereas the other presented lesions in the ribs. Both displayed the same morphology characteristics of diffused large cell lymphoma. They also exhibited the typical plasma cell phenotype. Immunohistochemical analysis revealed that the cells stained positively for CD38, CD138, and CD79a, and stained poorly or even negatively for CD20 and PAX-5. PET-CT scans demonstrated that it involved several body parts, such as lymph nodes and bones. CHOP regime, ESHAP, IGVE, and other intensive treatment regimes showed no satisfactory effect. Relapse appeared quickly after a brief remission, and both patients died 2 and 7 months, respectively, after the diagnosis. Conclusions We can conclude that PBL is very rare, but with high malignancy and poor prognosis. PBL patients are of low sensitivity to chemotherapy drugs and exhibit short-time survival. There is no standard chemotherapy regimen for PBL.

A Case Report with Plasmablastic Lymphoma of the Jejunum

Plasmablastic lymphoma (PBL) is a recently identified entity that is considered to be a type of diffuse large B-cell lymphoma with a unique immunophenotype and a predilection for the oral cavity of patients with the human immunodeficiency virus (HIV). Although its clinical features may help in the differential diagnosis, an extraoral location in a patient without HIV makes it more difficult to suspect clinically. This case report is the first to describe a patient with PBL originating from the jejunum in a 60-yr-old, HIV-seronegative man. Computed tomography of the face, chest and abdomen showed about a 9.4x9.0 cm mass of the proximal jejunum, multiple masses in the musculoskeletal soft tissue, and multiple lymphadenopathies. The histological examinations demonstrated a large cell lymphoma with plasmablastic differentiation. The neoplastic cells were diffusely positive for MUM1, epithelial membrane antigen and lambda light chains, and focally positive for CD79a; but negative for CD3, CD20, CD30, CD34, CD45RO, CD56, CD99, and CD117. The proliferation index by Ki-67 immunohistochemistry was approximately 70%. These findings were compatible with the diagnosis of PBL. The findings in this case suggest that PBL should be included in the differential diagnosis of a small bowel mass even in a HIV-negative patient.

Solitary Kaposi's Sarcoma of the Lower Lid in an HIV-Negative Patient

PURPOSE: To report a case of solitary Kaposi's sarcoma (KS) of eyelid in an HIV-negative patient, which has not yet been reported in domestics. CASE SUMMARY: A 76-year-old woman was seen at our clinic with a purplish nodular mass on her left lower lid that had grown up for 4 months prior. There were no abnormal findings in the body except eyelid. In the routine laboratory examinations, the result of HIV test was negative. The lesion was completely excised and the eyelid was reconstructed by semicircular rotational flap procedure. The histopathologic examination showed spindle cells of mild atypism, intermixed with slit-like vascular spaces and red blood cell extravastaion. These findings coincided with KS and polymerase chain reaction was positive for human herpes virus-8. During 10 months follow up, there was no evidence of tumor recurrence and systemic abnormalities. CONCLUSIONS: We experienced that Kaposi's sarcoma can occur solitarily in the eyelid of HIV-negative patient and favorable prognosis can be obtained by only surgical resection.

A case of plasmablastic lymphoma in the nasal cavity in a human immunodeficiency virus-negative patient / 대한내과학회지

Plasmablastic lymphoma is a recently identified entity that is considered to be a type of diffuse large B-cell lymphoma with a unique immunophenotype and a predilection for the oral cavity of human immunodeficiency virus (HIV) positive patients. We report a case of plasmablastic lymphoma presenting in nasal cavity of a 48-year-old, HIV-negative man. Cytologic and histologic examinations demonstrated a large cell lymphoma with plasmablastic differentiation. The tumor cells were positive for CD138, epithelial membrane antigen, but lacked expression of leukocyte common antigen, T-cell, and B-cell markers. Abundant Epstein-Barr virus-encoded RNA transcripts were identified by in situ hybridization. The lambda-light-chain restriction was demonstrated by in situ hybridization. These findings were compatible with plasmablastic lymphoma. Subsequent whole body FDG-PET scan revealed hypermetabolic lesions in the nasal cavity and left cervical lymph nodes level II,III,IV. To our knowledge, this is the first case of plasmablastic lymphoma in Korea.
