Abstract
Seronegative human immunodeficiency virus (HIV) infection, where an HIV-specific antibody response is lacking even in chronic or late-stage HIV infections, is extremely rare. Here, we report the case of a 50-year-old Japanese man presenting with Pneumocystis pneumonia who did not produce antibodies against HIV-1 until the initiation of antiretroviral therapy (ART). Fourth-generation antigen-antibody testing temporarily reverted from weakly positive to negative soon after initiating ART, likely due to a reduction in viral load (assessed by p24 antigen levels). His HIV-1 antibody titers remained low or indeterminate even after four years of ART. A literature review suggested that the absence of HIV-1-specific antibody production may be associated with unimpeded HIV replication and rapid CD4+ T cell decline. Seronegative HIV infection can lead to deferred diagnosis and treatment, thereby increasing the risk of transmitting the virus to others or developing opportunistic illnesses. It is important to combine multiple tests for diagnosis, depending on the medical condition. Further studies are required to investigate the host factors involved in the production of HIV-1-specific antibodies.

Abstract
HIV is a retrovirus that primarily infects CD4 presenting cells of the human immune system, such as macrophages and dendritic cells. People die of AIDS because the disease remains undetected for long periods of time. HIV diagnostic testing has come a long way since it was introduced in the early 1980s. Early diagnosis is key to successful treatment of HIV. Assay selection is based on initial screening results and clinical information provided by the physician, both of which are essential for the laboratory’s ability to make accurate diagnoses. Detecting HIV with high specificity and sensitivity in the early stages of infection requires simple, accurate and economical methods. In this chapter we have described the indications & criteria’s for HIV testing, HIV diagnosis by utilizing variety of immunological and molecular methods, like ELISA, rapid diagnostics, Western blotting, indirect immunoassays, and nucleic acid-based tests. Diagnostic laboratories must use testing algorithms to ensure the accuracy of results and the optimal use of lab resources. Participation in laboratory quality assurance programs are also essential to ensure that diagnostic laboratories provide accurate, timely and clinically relevant test results. HIV testing is the first step in maintaining a healthy life and preventing HIV transmission.

Abstract
BACKGROUND It is not uncommon for patients with human immunodeficiency virus (HIV) infections to visit the emergency department (ED) during seroconversion. However, patients with newly acquired HIV may not have a reactive screening result. We report a case of a patient who initially screened reactive on a fourth generation HIV test and subsequently nonreactive twice, but ultimately had positive viral load tests. CASE REPORT A 41-year-old woman experiencing symptoms of a sore throat, odynophagia, and back and flank pain for 5 days presented to the ED. The patient had a reactive HIV screen but negative confirmatory antibody test. The ED provider ordered a HIV viral load, informed the patient, and discharged with oral antibacterial agent. The patient returned the next day and after review of Visit 1 results, the ED provider ordered a second HIV screen, which had a nonreactive result. Another HIV viral load order was placed. The patient was discharged and returned a third time, 4 days after initial presentation. On this visit she was admitted, and the initial HIV viral load result returned positive. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We report a case of a patient who initially screened reactive on a fourth generation HIV screening and then twice nonreactive on the same screening test, ultimately having positive viral loads. The most probable explanation for her series of atypical HIV results is that the patient presented during the p24 seroconversion window, which is graphically conveyed in Figure 1. If her first screening had been performed during the window, no further test would have been performed to rule out HIV, contributing to misdiagnosis. ED providers need to be aware that, at some time points during seroconversion from "negative" to "positive", patients recently infected with HIV and manifesting prodromal symptoms may nonetheless have a negative screening result.

Abstract
INTRODUCTION Although HIV antibody tests have been widely accepted in clinical diagnosis of HIV infection, they may not be sufficient to diagnose all subjects with HIV infection. Except negative result of antibody test in the well-known" acute window phase", in rare cases, patients do not develop HIV antibodies despite demonstrable infection. Primary pulmonary Kaposi sarcoma (KS) without mucocutaneous involvement accounts for only 0-15% of all AIDS-related KS. KS is rare among Chinese subjects, especially in persons of Han descent. METHODS A case of seronegative AIDS with primary pulmonary Kaposi sarcoma (KS) was reported. It's a 46-year-old Chinese man presented with sore throat, hemoptysis, fever, dyspnea and multiple lung nodules. The lung lesions grew over a 5-month period so as the symptoms worsened. The possibility of AIDS was discounted by his physicians because of the repeatedly negative HIV antibodies tests despite the ELISA tests or Western blot tests. Histopathologic diagnosis of fine needle lung biopsy in local hospital was undetermined. After admission, HIV infection was eventually confirmed by plasma HIV RNA testing. Histopathologic diagnosis of Lung Kaposi sarcoma was made through repeated fine needle aspiration biopsy as well as the review of former one. Multiple antibiotics and chemotherapy were administrated with no clinical effect due to advanced stage and the patient passed away soon after diagnosis. RESULTS This is the first case of seronegative HIV-1 infection with presentation of primary pulmonary KS. CONCLUSION This case underscores the importance of plasma RNA test in conjunction with HIV antibody test for some rare patients with HIV infection who present with severe immunodeficiency and opportunistic infections or malignancy.

Abstract
BACKGROUND With the use of the framework advocated by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group, our aims were to perform a systematic review and to develop evidence-based recommendations that may be used to answer the following PICO [Population, Intervention, Comparator, Outcomes] question:In the obtunded adult blunt trauma patient, should cervical collar removal be performed after a negative high-quality cervical spine (C-spine) computed tomography (CT) result alone or after a negative high-quality C-spine CT result combined with adjunct imaging, to reduce peri-clearance events, such as new neurologic change, unstable C-spine injury, stable C-spine injury, need for post-clearance imaging, false-negative CT imaging result on re-review, pressure ulcers, and time to cervical collar clearance? METHODS Our protocol was registered with the PROSPERO international prospective register of systematic reviews on August 23, 2013 (REGISTRATION NUMBER: CRD42013005461). Eligibility criteria consisted of adult blunt trauma patients 16 years or older, who underwent C-spine CT with axial thickness of less than 3 mm and who were obtunded using any definition.Quantitative synthesis via meta-analysis was not possible because of pre-post, partial-cohort, quasi-experimental study design limitations and the consequential incomplete diagnostic accuracy data. RESULTS Of five articles with a total follow-up of 1,017 included subjects, none reported new neurologic changes (paraplegia or quadriplegia) after cervical collar removal. There is a worst-case 9% (161 of 1,718 subjects in 11 studies) cumulative literature incidence of stable injuries and a 91% negative predictive value of no injury, after coupling a negative high-quality C-spine CT result with 1.5-T magnetic resonance imaging, upright x-rays, flexion-extension CT, and/or clinical follow-up. Similarly, there is a best-case 0% (0 of 1,718 subjects in 11 studies) cumulative literature incidence of unstable injuries after negative initial imaging result with a high-quality C-spine CT. CONCLUSION In obtunded adult blunt trauma patients, we conditionally recommend cervical collar removal after a negative high-quality C-spine CT scan result alone. LEVEL OF EVIDENCE Systematic review, level III.

Identification of human immunodeficiency virus-1 (HIV-1) transmission from a 29-year-old daughter to her mother in Shanghai, China. Arch Virol 2012; 158:11-7.

Abstract
BACKGROUND AND METHODS Routes of intrafamilial transmission of HIV-1 are not always clear. Here, we describe transmission to a mother from her 29-year-old daughter within a family setting through clinical, epidemiological and molecular evidence. We evaluated the risk factors for intrafamilial transmission of HIV-1 infection through qualitative epidemiology following pol and env gene sequencing and phylogenetic analysis. RESULT The nucleotide sequences of the pol and env genes of the two strains from the two patients in the family were 99 % and 100 % identical, respectively, and they clustered with CRF07_BC, which includes the main recombinant strains in Shanghai, China. The diversity of genetic clones between the env and pol genes was insignificant (p > 0.05). The drug-resistance-associated mutation positions of the two viral strains were basically similar and indicated that both were susceptible to the first-line anti-retroviral drugs including zidovudine (AZT), lamivudine (3TC), efavirenz (EFV) and nevirapine (NVP) prior to the initiation of highly active antiretroviral treatment (HAART), providing additional evidence of a close similarity between the quasispecies of the two family members. CONCLUSION In this family, the two strains of the virus, isolated from the mother and her adult daughter, had very high homology. In the context of their clinical histories, we can make a conclusion that the mother was infected by the virus in her daughter's blood or other body fluids, but no overt transmission route has been clarified. This investigation also suggested that intimate personal exposure in the same household can contribute to HIV-1 transmission and underscores the need to educate persons who care for or are in contact with HIV-infected persons in household settings where such exposures may occur.

Abstract
HIV-1-specific antibodies can be detected in HIV-1-positive patients within weeks of primary infection. Rare cases have been reported of patients who are persistently seronegative despite evidence of HIV-1 infection. We present a retrospective review of the clinical, virologic and immunologic characteristics of 25 persistently seronegative patients whose cases have been published to date and postulate a biologic mechanism for this phenomenon.
