Abstract
BACKGROUND The prevalence of AIDS-related Kaposi's sarcoma (KS) has been reducing following the widespread use of highly-active anti-retroviral therapy (HAART). In Nigeria, recent trends in the prevalence of KS in HIV-infected patients has not been described. We determined the prevalence, clinical pattern and treatment outcome of AIDS-related KS in Zaria, Nigeria. METHODS Over a 5-year period, a retrospective study was conducted at the HIV treatment and care centre of Ahmadu Bello University Teaching Hospital, Zaria and all patients with histologically confirmed AIDS-related KS were included. RESULTS A total of 4721 patients were enrolled during the period under review, out of which 45 were diagnosed with AIDS related KS, which constituted 0.95% of all patient seen. The male to female ratio was 1:1.5 with a mean age of 35.2 ± 6.5 years. Twenty-six (58%) were on HAART, with median duration of 4 months (IQR: 1-31 months) between HAART commencement and KS diagnosis, while KS was reported as presenting illness in 19 (42%) patients. The lower extremity was the most frequently involved site in 24 (53.3%) patients and disseminated disease was present in 14 (31.1%) patients, commoner in the HAART-naïve group. Following KS treatment, 27 (60%) patients recovered fully, 12 (26.7%) died, while 6 (13.3%) were lost to follow up. Disseminated disease, male gender, and low CD4+ T-cell count was associated with higher mortality. CONCLUSION Kaposi's sarcoma remains an important AIDS defining illness though with a decreasing prevalence. Early diagnosis and treatment should be prioritized at the time of HAART initiation in HIV service delivery programs in Nigeria.

Abstract
In 2020, over 34 000 cases of Kaposi sarcoma (KS) were estimated globally, all attributable to KS herpesvirus (KSHV). Prior to the HIV epidemic, KS already existed in KSHV endemic regions, notably in sub-Saharan Africa (SSA). The HIV epidemic has vastly increased the KS burden. We developed a methodology to provide global estimates of KS burden according to HIV status. A systematic review identified studies reporting HIV prevalence in consecutive KS series. Pooled estimates of HIV prevalence, by country or UN subregion, were used to calculate population-attributable fraction (PAF) and these were applied to IARC's GLOBOCAN 2020 to estimate burden and incidence of HIV-attributable and non-HIV-attributable KS. We identified 55 eligible studies, reporting HIV prevalence ranging from ≤5% to ≥95%. Approximately 80% of KS in SSA was estimated attributable to HIV, vs ~50% in the rest of the world. By applying PAFs to national GLOBOCAN estimates, an estimated 19 560 KS cases attributable to HIV were diagnosed in SSA in 2020 (~80% of the worldwide burden), vs 5064 cases of non-HIV-attributable KS (~60% of the worldwide burden). Incidence of HIV-attributable KS was highest in Southern Africa (6.0 cases per 100 000) and Eastern Africa (3.4), which were also the world regions with highest incidence of non-HIV-attributable KS (0.4 and 1.0 cases per 100 000, respectively). This first systematic effort to produce a global picture of KS burden stratified by HIV status highlights the continuing important burden of HIV-attributable KS in SSA, even in the era of combined antiretroviral therapy.

Abstract
Kaposi Sarcoma (KS) is the most common AIDS-defining cancer, even as HIV-positive people live longer. Like other herpesviruses, human herpesvirus-8 (HHV-8) establishes a lifelong infection of the host that in association with HIV infection may develop at any time during the illness. With the increasing global incidence of KS, there is an urgent need of designing optimal therapeutic strategies for HHV-8-related infections. Here we formulate two models with innate and adaptive immune mechanisms, relevant for non-AIDS KS (NAKS) and AIDS-KS, where the initial condition of the second model is given by the equilibrium state of the first one. For the model with innate mechanism (MIM), we define an infectivity resistance threshold that will determine whether the primary HHV-8 infection of B-cells will progress to secondary infection of progenitor cells, a concept relevant for viral carriers in the asymptomatic phase. The optimal control strategy has been employed to obtain treatment efficacy in case of a combined antiretroviral therapy (cART). For the MIM we have shown that KS therapy alone is capable of reducing the HHV-8 load. In the model with adaptive mechanism (MAM), we show that if cART is administered at optimal levels, that is, 0.48 for protease inhibitors, 0.79 for reverse transcriptase inhibitors and 0.25 for KS therapy, both HIV-1 and HHV-8 can be reduced. The predictions of these mathematical models have the potential to offer more effective therapeutic interventions in the treatment of NAKS and AIDS-KS.

Abstract
OBJECTIVES The accurate prevalence of acquired immunodeficiency syndrome (AIDS)-defining illnesses (ADIs) in human immunodeficiency virus (HIV)-infected patients has not been well investigated. Hence, a longitudinal nationwide surveillance study analyzing the current status and national trend of opportunistic complications in HIV-infected patients in Japan is warranted. METHODS A nationwide surveillance of opportunistic complications in HIV-infected patients from 1995 to 2017 in Japan was conducted. An annual questionnaire was sent to 383 HIV/AIDS referral hospitals across Japan to collect information (CD4+ lymphocyte count, time of onset, outcome, and antiretroviral therapy [ART] status) of patients diagnosed with any of 23 ADIs between 1995 and 2017. RESULTS The response and case capture rates of the questionnaires in 2017 were 53% and 76%, respectively. The number of reported cases of opportunistic complications peaked in 2011 and subsequently declined. Pneumocystis pneumonia (38.7%), cytomegalovirus infection (13.6%), and candidiasis (12.8%) were associated with the cumulative incidence of ADIs between 1995 and 2017. The mortality rate in HIV-infected patients with opportunistic complications substantially decreased to 3.6% in 2017. The mortality rate was significantly higher in HIV patients who received ART within 14 days of diagnosis of complications than in those who received ART 15 days after diagnosis (13.0% vs. 3.2%, p < 0.01). CONCLUSIONS We have demonstrated a 23-year trend of a newly diagnosed AIDS status in Japan with high accuracy. The current data reveal the importance of Pneumocystis pneumonia as a first-onset illness and that early initiation of ART results in poor outcomes in HIV patients in Japan.

Abstract
With the advent of antiretroviral therapy (ART), the prognosis of people infected with human immunodeficiency virus (HIV) has improved, and the frequency of HIV-related central nervous system (CNS) diseases has decreased. Nevertheless, mortality from HIV-related CNS diseases, including those associated with ART (e.g., immune reconstitution inflammatory syndrome) remains significant. Magnetic resonance imaging (MRI) can improve the outlook for people with HIV through early diagnosis and prompt treatment. For example, HIV encephalopathy shows a diffuse bilateral pattern, whereas progressive multifocal leukoencephalopathy, HIV-related primary CNS lymphoma, and CNS toxoplasmosis show focal patterns on MRI. Among the other diseases caused by opportunistic infections, CNS cryptococcosis and CNS tuberculosis have extremely poor prognoses unless diagnosed early. Immune reconstitution inflammatory syndrome shows distinct MRI findings from the offending opportunistic infections. Although distinguishing between HIV-related CNS diseases based on imaging alone is difficult, in this review, we discuss how pattern recognition approaches can contribute to their early differentiation.

Abstract
The prevalence of asymptomatic cryptococcal antigenemia (ACA) in human immunodeficiency virus (HIV) infected individuals has been observed to be elevated. The prevalence of ACA ranges from 1.3% to 13%, with different rates of prevalence in various regions of the world. We reviewed studies conducted internationally, and also referred to two established expert consensus guideline documents published in China, and we have concluded that Chinese HIV-infected patients should undergo cryptococcal antigen screening when CD4 T-cell counts fall below 200 cells/μL and that the recommended treatment regimen for these patients follow current World Health Organization guidelines, although it is likely that this recommendation may change in the future. Early screening and optimized preemptive treatment for ACA is likely to help decrease the incidence of cryptococcosis, and is lifesaving. Further studies are warranted to explore issues related to the optimal management of ACA.

Abstract
BACKGROUND Infection with the Human Immunodeficiency Virus (HIV) dramatically increases the risk of developing active tuberculosis (TB). Several studies have indicated that co-infection with TB increases the risk of HIV progression and death. Sub-Saharan Africa bears the brunt of these dual epidemics, with about 2.4 million HIV-infected people living with TB. The main objective of our study was to assess whether the pre-HAART CD4+ T-lymphocyte counts and percentages could serve as biomarkers for post-HAART treatment immune-recovery in HIV-positive children with and without TB co-infection. METHODS The data analyzed in this retrospective study were collected from a cohort of 305 HIV-infected children being treated with HAART. A Lehmann family of ROC curves were used to assess the diagnostic performance of pre- HAART treatment CD4+ T-lymphocyte count and percentage as biomarkers for post-HAART immune recovery. The Kaplan-Meier estimator was used to compare differences in post-HAART recovery times between patients with and without TB co-infection. RESULTS We found that the diagnostic performance of both pre-HARRT treatment CD4+ T-lymphocyte count and percentage was comparable and achieved accuracies as high as 74%. Furthermore, the predictive capability of pre-HAART CD4+ T-lymphocyte count and percentage were slightly better in TB-negative patients. Our analyses also indicate that TB-negative patients have a shorter recovery time compared to the TB-positive patients. CONCLUSIONS Pre-HAART CD4+ T-lymphocyte count and percentage are stronger predictors of immune recovery in TB-negative pediatric patients, suggesting that TB co-infection complicates the treatment of HIV in this cohort. These findings suggest that the detection and treatment of TB is essential for the effectiveness of HAART in HIV-infected pediatric patients.

Abstract
Among 66 antiretroviral-naive children aged <3 years with human immunodeficiency virus (HIV) or coinfected with HIV and tuberculosis and initiating efavirenz-based antiretroviral therapy (ART), non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance was detected before ART in 5 (7.6%). Virologic failure occurred in 2 of these children; they were last tested at 16 and 24 weeks of ART. Pre-ART NNRTI resistance was not associated with virologic failure.

Abstract
The article presents a review of current literature data on the development of opportunistic toxoplasmosis in patients suffering from HIV infection and a clinical case of an immunocompromised patient with toxoplasmosis. Current information concerning the incidence of toxoplasmosis in Russia and other countries are presented. Special attention is paid to the Toxoplasma gondii interactions with the host cell in HIV-infected people. The mechanism of parasite penetration into the host cell and subsequent modifications that the parasite makes with the occupied cell are analyzed in detail. The significance of the chosen topic is illustrated by the description of a clinical case of toxoplasmosis in an HIV-infected patient. The authors hope that the article will help to attract attention of the professional community to the problem of opportunistic infections in HIV/AIDS carriers, and in particular to the mechanisms of the "parasite-host" interactions in patients with toxoplasmosis.

Abstract
Talaromycosis is a disseminated disease caused by Talaromyces (Penicillium) marneffei, mainly seen in acquired immunodeficiency syndrome (AIDS) patients. Its distribution is restricted to southeast Asian countries; a small pocket of endemicity exists in the northeast Indian state of Manipur. Here, we present a series of five cases presenting to our tertiary care hospital, originating from non-endemic states neighboring Manipur. In addition to the geographical distinction, a variety of unique features were noted in our cases, including human immunodeficiency virus (HIV)-negative hosts, the absence of typical skin lesions, presentation as pneumonia and generalized lymphadenopathy. Our series highlights the importance of distinguishing this disease from histoplasmosis and tuberculosis, both endemic in India.

Abstract
RATIONALE Non-traumatic bowel perforation caused by cytomegalovirus (CMV) and Mycobacterium avium complex (MAC) infections has become rare among patients with acquired immunodeficiency syndrome (AIDS) in the era of combination antiretroviral therapy (cART); however, CMV-associated and MAC-related immune reconstitution inflammatory syndrome (IRIS) has subsequently emerged owing to the wide use of integrase inhibitor-based regimens. Here we report a case of spontaneous perforation of the jejunum in a patient with human immunodeficiency virus (HIV) infection with good compliance to cART. PATIENT CONCERNS A 32-year-old HIV-infected man developed CMV disease and DMAC infection, as unmasking IRIS, 3 days after the initiation of cART. After appropriate treatment for opportunistic infections, intermittent fever with enlarged lymph nodes in the abdomen occurred as paradoxical IRIS. The patient was administered prednisolone with subsequent tapering according to his clinical condition. DIAGNOSES Unexpected perforation of hollow organ during the titration of steroid dose with clinical presentations of severe abdominal pain was diagnosed by chest radiography. INTERVENTIONS He underwent surgical repair with peritoneal toileting smoothly. OUTCOMES He was discharged well with a clean surgical wound on post-operative day 10. LESSONS Bowel perforation may be a life-threatening manifestation of IRIS in the era of cART. Steroids should be avoided, if possible, to decrease the risk of bowel perforation, especially in IRIS occurred after opportunistic diseases involving the gastrointestinal tract.

Abstract
BACKGROUND To evaluate clinical outcomes after either immediate or deferred initiation of antiretroviral therapy in HIV-1-infected patients, presenting late with pneumocystis pneumonia (PCP) or toxoplasma encephalitis (TE). METHODS Phase IV, multicenter, prospective, randomized open-label clinical trial. Patients were randomized into an immediate therapy arm (starting antiretroviral therapy (ART) within 7 days after initiation of OI treatment) versus a deferred arm (starting ART after completing the OI-therapy). All patients were followed for 24 weeks. The rates of clinical progression (death, new or relapsing opportunistic infections (OI) and other grade 4 clinical endpoints) were compared, using a combined primary endpoint. Secondary endpoints were hospitalization rates after completion of OI treatment, incidence of immune reconstitution inflammatory syndrome (IRIS), virologic and immunological outcome, adherence to proteinase-inhibitor based antiretroviral therapy (ART) protocol and quality of life. RESULTS 61 patients (11 patients suffering TE, 50 with PCP) were enrolled. No differences between the two therapy groups in all examined primary and secondary endpoints could be identified: immunological and virologic outcome was similar in both groups, there was no significant difference in the incidence of IRIS (11 and 10 cases), furthermore 9 events (combined endpoint of death, new/relapsing OI and grade 4 events) occurred in each group. CONCLUSIONS In summary, this study supports the notion that immediate initiation of ART with a ritonavir-boosted proteinase-inhibitor and two nucleoside reverse transcriptase inhibitors is safe and has no negative effects on incidence of disease progression or IRIS, nor on immunological and virologic outcomes or on quality of life.

Abstract
The relationship between retinal microangiopathy and some features of human immunodeficiency virus (HIV) infection such as HIV antigenemia, antibodies to the viral proteins, T lymphocyte subsets, were studied in 71 patients with acquired immunodeficiency syndrome (AIDS). The absence of antibodies to the HIV p24 protein was significantly related to retinal microangiopathy (p = 0.0051) and more closely to retinal cotton-wool spots (p = 0.0007); the combination of positive antigenemia with the absence of antibodies to p24, which is typical of the later phases of HIV infection, was found in a larger percentage of patients with cotton-wool spots (p = 0.0013) than in subjects with every sign of microangiopathy (p = 0.0546). T-helper (CD4+) cells count below 200 cells/mm3 was also detected in a higher percentage of patients with HIV-related retinal microangiopathy (p = 0.009). These findings suggest that retinal microangiopathy and especially retinal cotton-wool spots are related to the progression of immunodeficiency.

Abstract
OBJECTIVE To study the accuracy of lactic dehydrogenase (LDH) in the diagnosis of pneumocystis pneumonia (PCP). METHODS The data of this systemic review was retrieved from the PubMed, China Biology Medicine disc, Wanfang, Weipu and China National Knowledge Infrastructure (CNKI) databases from establishment till to October 31st, 2017. Case-control studies about the diagnosis of PCP were enrolled. Enrolled studies were required that patients in case group ware PCP and patients in control group were lung diseases other than PCP. The QUADAS tool was used to evaluate the quality of studies. The RevMan 5.3 software was used to draw a forest plot. The StataMP 14 software was used to make subgroup analyses by drawing receiver operator characteristic (SROC) curves for the whole group, the acquired immune deficiency syndrome (AIDS) group, and the not all-AIDS group, and calculating their diagnostic odds ratio (DOR) and 95% confidential interval (95%CI). RESULTS Thirteen studies, all in English, were included. There were 825 patients in the case group, in which 650 patients were AIDS. There were 1 341 patients in control group, in which 888 patients were AIDS and most of them were Pulmonary Kaposi Sarcoma, bacterial pneumonia, pulmonary tuberculosis etc. Although there were different positive values of LDH in different studies, from 200 U/L to 598 U/L, sensitivities were good, especially in AIDS patients all values were above 80% (80%-100%). The specificities had big fluctuations, from 6% to 85%, which made them poor. The DOR (95%CI) of LDH in PCP diagnosis of all patients, AIDS patients and not-all AIDS patients were 6.73 (3.19-14.21), 9.17 (3.79-22.18) and 5.07 (1.30-19.80) respectively. CONCLUSIONS The sensitivity of LDH in the diagnosis of PCP is high, especially in AIDS group. In practice if LDH is negative, there should be more evidences to support the treatment of PCP.

Abstract
Genitourinary tract is the second most common site where extrapulmonary tuberculosis (TB) occurs. Genitourinary TB is notable for a latent clinical course and difficult diagnosis. The paper presents clinical observations of two patients treated in a urology department of a general public hospital. One of them was diagnosed with tuberculosis of the prostate, MTB+. In the other, TB of the prostate was suspected based on pathologic assessment of the surgical specimen after surgery for prostate cancer.

Abstract
There is growing concern that although the more severe forms of HIV-associated neurologic deficits are reduced following highly active anti-retroviral therapy (HAART), mild to moderate cognitive disorders may persist for years after HAART initiation and this may occur despite complete plasma viral suppression. According to the UNAIDS 2014 report, there were 3.2 million children living with HIV around the world at the end of 2013 and 91 % of these resided in sub-Saharan Africa. In the same year, only 24 % of children who needed antiretroviral treatment (ART) received it and 190,000 children died of AIDS-related illnesses. We propose that behavioral interventions are needed in combination with medical treatment and care in order to fully address the needs of children and adolescents in Africa living with HIV. In early childhood, caregiver training programs to enhance the developmental milieu of the child with HIV can enhance their cognitive and social development and that such interventions are both feasible and well-accepted by the local population. For school-age children, computerized cognitive rehabilitation training can be an entertaining and engaging way to improve attention, working memory, and problem solving skills for children with HIV. Further dissemination and implementation science work is needed for arriving at cost-effective strategies for scaling up such behavioral interventions in African resource-constrained settings, given that the vast majority of HIV-affected children and youth worldwide presently live in sub-Saharan Africa.

Abstract
IMPORTANCE New data and therapeutic options warrant updated recommendations for the use of antiretroviral drugs (ARVs) to treat or to prevent HIV infection in adults. OBJECTIVE To provide updated recommendations for the use of antiretroviral therapy in adults (aged ≥18 years) with established HIV infection, including when to start treatment, initial regimens, and changing regimens, along with recommendations for using ARVs for preventing HIV among those at risk, including preexposure and postexposure prophylaxis. EVIDENCE REVIEW A panel of experts in HIV research and patient care convened by the International Antiviral Society-USA reviewed data published in peer-reviewed journals, presented by regulatory agencies, or presented as conference abstracts at peer-reviewed scientific conferences since the 2014 report, for new data or evidence that would change previous recommendations or their ratings. Comprehensive literature searches were conducted in the PubMed and EMBASE databases through April 2016. Recommendations were by consensus, and each recommendation was rated by strength and quality of the evidence. FINDINGS Newer data support the widely accepted recommendation that antiretroviral therapy should be started in all individuals with HIV infection with detectable viremia regardless of CD4 cell count. Recommended optimal initial regimens for most patients are 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (InSTI). Other effective regimens include nonnucleoside reverse transcriptase inhibitors or boosted protease inhibitors with 2 NRTIs. Recommendations for special populations and in the settings of opportunistic infections and concomitant conditions are provided. Reasons for switching therapy include convenience, tolerability, simplification, anticipation of potential new drug interactions, pregnancy or plans for pregnancy, elimination of food restrictions, virologic failure, or drug toxicities. Laboratory assessments are recommended before treatment, and monitoring during treatment is recommended to assess response, adverse effects, and adherence. Approaches are recommended to improve linkage to and retention in care are provided. Daily tenofovir disoproxil fumarate/emtricitabine is recommended for use as preexposure prophylaxis to prevent HIV infection in persons at high risk. When indicated, postexposure prophylaxis should be started as soon as possible after exposure. CONCLUSIONS AND RELEVANCE Antiretroviral agents remain the cornerstone of HIV treatment and prevention. All HIV-infected individuals with detectable plasma virus should receive treatment with recommended initial regimens consisting of an InSTI plus 2 NRTIs. Preexposure prophylaxis should be considered as part of an HIV prevention strategy for at-risk individuals. When used effectively, currently available ARVs can sustain HIV suppression and can prevent new HIV infection. With these treatment regimens, survival rates among HIV-infected adults who are retained in care can approach those of uninfected adults.

Abstract
Care of patients with HIV infection starts with diagnosis as soon as possible, preferably at or near the time of acute infection. Opportunistic infections, malignancies, and other conditions develop progressively over time, particularly in untreated patients. The AIDS-defining opportunistic infections most common in the United States include Pneumocystis jirovecii pneumonia, Candida esophagitis, toxoplasmic encephalitis, tuberculosis, disseminated Mycobacterium avium complex, cryptococcal meningitis, and cytomegalovirus retinitis. Specific prophylaxis regimens exist for several opportunistic infections, and effective antiretroviral therapy reduces the risk of most others. Other AIDS-defining conditions include wasting syndrome and HIV encephalopathy. AIDS-defining malignancies include Kaposi sarcoma, systemic non-Hodgkin lymphoma, primary central nervous system lymphoma, and invasive cervical cancer. Although not an AIDS-defining condition, anal cancer is common in patients with HIV infection. Other HIV-related conditions include thrombocytopenia, recurrent bacterial respiratory infections, HIV-associated nephropathy, and HIV-associated neurocognitive disorder.

Abstract
Background Being the most backward region, The Far Western Development Region has high illiteracy rate, low socioeconomic status and high migration rate contributing the progression of epidemiological status of Human Immunodeficiency Virus (HIV) towards generalized form. Objective To study the demographic profile of the HIV positive patients, along with their CD4 status and tuberculosis during diagnosis. Method A retrospective descriptive study carried out from May 2006 to July 2012 in 271 HIV patients registered in HIV clinic of Mahakali Zonal Hospital, Mahendranagar. Result Among 271 patients enrolled, 48.30% (131) were male and 51.7% (140) were females. Thirty seven (13.7%) were less than 15 years and 76.3% (207) were of age 16-45 years. 38.7% were household workers by occupation and 34.50% were involved in agriculture and 3.70%were migrant labour. At the time of presentation, 22.4% (60) were stage I according to WHO staging and 18.5% (50), 58.5 (158) and 0.7% (2) were of stage II, III and IV respectively. Similarly, 33.0% (89) had more than 350 CD4 count at the time of presentation. 20.8% (56) of patients were infected with tuberculosis. Among 236 families, 2 or more members were found to be affected in 24 families. In most of the cases, female were diagnosed first followed by male in the families, where both the couple were infected. Conclusion Most of the HIV infected patients were of productive age group. Majority of patients were uneducated and Tuberculosis was found to be common opportunistic infections associated with HIV infection.

Abstract
OBJECTIVE To analyze the outcome among HIV-infected children following antiretroviral treatment in Shandong province. METHODS From the national AIDS antiviral treatment database during April 2009 and December 2013, 50 children who were according to antiviral treatment in Shandong province were classified as the cases. Regular follow-up observation and test were conducted among children under antiretroviral therapy before treatment,0.5(th), 1(th), 2(th), 3(th), 6(th), 9(th), 12(th) months after treatment, and then one time after every 3 months follow-up after one year. The height and weight of the children under antiretroviral therapy and normal children (2010 national student physical health survey results)were compared during different times. And the height and weight of the follow-up period of situation, the CD4(+)T cell count and viral load, regular physical examination results, the incidence of opportunistic infections were compared with baseline data. RESULTS Among the 50 children under antiviral therapy, male accounted for 54.0% (27/50) , female 46.0% (23/50) , the youngest was 2 years of age, the oldest was 15 years old, and all of them were transmitted by the mother-to-child route and none received mother-to-child prevention. The shortest treatment time lasted five months, the longest 61 months, with a median 25 months. The height of the baseline, 12(th), 24(th), 36(th) months after antiviral treatment were ( 111.9 ± 23.4), (118.1 ± 20.9), (127.1 ± 13.9), (135.4 ± 10.2)cm, and weigh were ( 20.6 ± 8.7), (23.8 ± 6.3), (27.8 ± 7.2), (30.7 ± 5.5) kg, respectively. The height and weight of the treated children were higher than those in the baseline (P < 0.05), but lower than those among the children without HIV infection. The CD4(+)T lymphocytes level of the baseline, 3(th), 6(th), 12(th), 24(th), 36(th) months after antiviral treatment were 224.0, 279.5, 465.0, 581.0, 640.0, 728.0/µl, the CD4(+)T lymphocytes level after antiviral treatment were higher than the baseline (P < 0.05). Hemoglobin and AST were significantly different between children received treatment after 24 months and those in the baseline (P < 0.05), baseline and 24(th) months after treatment the hemoglobin value were (106.6 ± 22.2), (125.2 ± 5.8), and the AST measurements were (42.1 ± 23.1), (23.4 ± 15.6). Baseline and 12(th), 24(th) months after treatment, the median of viral load were 10 000.0, 105.0,0.0 copies/ml , and the ratio of viral load ≤ 400 copies/ml were 50% (4/8) , 65% (22/34) , 88% (14/16) , respectively, the results of viral load had significant difference among 12(th), 24(th) months after antiviral treatment and baseline (P < 0.05). The incidence of opportunistic infections was 62% (31/50) before treatment, and 12% (6/50) after the antiviral therapy. CONCLUSION Antiviral therapy can effectively improve the immunity and reduce the incidence of opportunistic infections which is helpful to improve the quality of life among HIV-infected children following antiretroviral treatment in Shandong province.

Abstract
OBJECTIVE To investigate the morphological features of HIV-associated tuberculosis with different peripheral blood CD4 lymphocyte counts. MATERIAL AND METHODS Intraoperative and biopsy specimens from 148 patients with HIV-associated tuberculosis were examined. Group 1 included 16 (10.8%) patients having a CD4+ lymphocyte count above 350 cells/μl; Group 2 comprised 38 (25.7%) patients having 200 to 349 cells/μl; Group 3 consisted of 94 (63.5%) patients with a CD4+ lymphocyte count below 200 cells/μl. Histological and immunohistochemical studies and a polymerase chain reaction assay were used. RESULTS According to the predominant inflammatory phase, all analyzed cases were divided into 4 patterns of tissue responses: 1) typical productive granulomatous tuberculous inflammation; 2) obscure productive granulomatous inflammation; 3) a predominant alterative phase with the formation of pyonecrotic foci; 4) a predominant exudative tissue response with the development of amorphofunctional pattern typical of nonspecific inflammation. A relationship was found between the count of CD4+ lymphocytes and the predominant pattern of a tissue inflammatory response. A productive component of inflammation prevailed in Group 1; a mild productive response with the significantly obscure features of a granulomatous process was dominant in Group 2; alterative phenomena were noted in Group 3. Most patients (n=132, 89.2%) were stated to have an obscure granulomatous response (n=61, 41.2%), and a preponderance of an alternative (n=48, 32.4%) and vascular (n=23, 15.6%) components of inflammation. CONCLUSION The magnitude of alterative and exudative components in the foci of tuberculous inflammation suggested that there was a change-over from a delayed hypersensitivity reaction that was typical of tuberculosis to an immediate hypersensitivity reaction and reflected severe immune system dysfunction.

Abstract
OBJECTIVE To determine the clinical characteristics of HIV infected patients in China in order to improve early recognition and diagnosis of AIDS. METHODS A total of 297 newly diagnosed HIV/AIDS patients were enrolled in Peking Union Medical College Hospital (PUMCH) from January 2001 to December 2012, including 19 patients of primary phase, 115 of asymptomatic phase and 163 of AIDS phase. Clinical characteristics of these patients were retrospectively analyzed. RESULTS Two hundred and nineteen out of 297 patients reported clinical symptoms with variety. The main systemic symptoms included fever (100 cases, 33.7%), weight loss (50 cases, 16.8%) and fatigue (38 cases, 12.8%). Organ involvement included mucocutaneous (67 cases, 22.6%), respiratory (62 cases, 20.9%), gastrointestinal (40 cases, 13.5%) systems. Patients in AIDS phase were more symptomatic. Seventy-three out of 173 (42.2%)patients have been referred by 2 healthcare providers at least before the diagnosis of HIV infection was confirmed. Initial diagnoses were made in Departments of Infectious Diseases (36.9%), Gastroenterology (16.4%), and Emergency (13.7%). Opportunistic infections accounted for most AIDS defining conditions (ADC), including pneumocystis jiroveci pneumonia (PCP) (36 cases, 22.1%), cytomegalovirus infection (25 cases, 15.3%) and tuberculosis (22 cases, 13.5%). Median peripheral CD(+)4 T lymphocyte count in patients with ADC were 36 cells/µl. CONCLUSIONS Common clinical presentations of HIV/AIDS included fever, weight loss, diarrhea, short of breath and mucocutaneous lesions. Opportunistic infections mainly affected respiratory and gastrointestinal system, with PCP the most common one. The diagnosis of HIV infection was delayed in most cases, suggesting that more efforts are required especially in universal education of clinicians and accurate viral detection.

Abstract
The field of HIV medicine has changed rapidly in the last two decades since effective and tolerable antiretroviral treatment became available. As a result, although classical opportunistic infections of the brain have become less common, clinicians need to be aware of a wider range of acute and chronic complications of HIV and its treatment. In this article, we summarise major opportunistic infections, immune reconstitution inflammatory syndrome, HIV-associated neurocognitive disorders, and cerebrovascular disease in HIV positive patients. We also emphasise the preventability and reversibility of most of the central nervous system complications of HIV, and hence the importance of early diagnosis of HIV and involvement of clinicians with special expertise in HIV medicine.

Abstract
Acquired immune deficiency syndrome (AIDS) is a kind of fatal disease which involve multiple organs and the public health of global intention. The incidence rate in China is escalating obviously. Currently there is lack of large samples and long-term systematic observations of ocular pathological changes in the human immunodeficiency virus (HIV) infected and AIDS patients. Diagnostic errors and missed diagnosis still exist in hospitals, even in some advanced hospitals. They delay the therapy of patients, also easily result in hospital acquired infections. It is notable that there is insufficient attention to preoperative test of anti-HIV in some hospitals, especially in outpatient surgeries. Therefore potential iatrogenic infection risks are hidden. Some clinical doctors are afraid of AIDS patients, therefore they are lack of subjective initiative to comprehensively examination and treatment the patients. For the past few years, highly active antiretroviral therapy is widely used, AIDS related morbidity and mortality is significantly reduced, and the prevalence rate of ocular complications decreased from 55% to 95%. But due to the HIV/AIDS patient volume increased year by year, and the survival rate raised, prolonged survival, results in the increase of the absolute number of patients with ocular complications. Therefore it is critical to pay attention to the HIV/AIDS ocular lesions in the diagnosis and treatment of iatrogenic infection.

Abstract
BACKGROUND The chronic use of antifungal agents in the treatment of fungal infection in general and oropharyngeal candidiasis mainly in AIDS patient's leads to the selection of strain resistant to these therapies and a shift in the spectrum of Candida species. This study determines the species diversity and in vitro susceptibility of Candida isolates from late presenting AIDS patients in northwest Ethiopia. METHODS Two hundred and twenty one HIV/AIDS patients were assessed with a standardized evaluation form at enrolment. Oral rinses were cultured on CHROMagar plates at 37°C for 48 hours and Candida species identification were made following standard microbiological techniques. In vitro drug susceptibility tests were made using broth microdilution method. RESULTS The colonization rate of Candida species was found to be 82.3% (177/215). C. albicans was the predominant species isolated from 139 (81%) patients but there was a diversity of other species. C. glabrata was the most frequent non-albicans species isolated in 22.5% (40/177) of the patients followed by C. tropicalis 14.1% (27/177), C. krusei 5.6% (10) and other unidentifiable Candida species 4% (7/177). Recurrent episodes of oropharyngeal candidiasis and previous exposure to antifungal drugs were found to be predisposing factors for colonization by non-albicans species. Irrespective of the Candida species identified 12.2% (11/90), 7.7% (7/90) and 4.7% (4) of the isolates were resistant to fluconazole, ketoconazole and itraconazole, respectively. In contrast, resistance to micafungin, amphotericin B and 5-Fluorocytosine was infrequent. CONCLUSION HIV/AIDS patients are orally colonized by single or multiple albicans and non- albicans Candida species that are frequently resistant to azoles and occasionally to amphotericin B, 5-Fluorocytosine and micafungin. These highlight the need for national surveillance for examining Candida epidemiology and resistance to antifungal drugs.

Abstract
Background Immune reconstitution inflammatory syndrome (IRIS) is a widely recognised complication of antiretroviral therapy (ART), but there are still limited data from resource-limited settings. Our objective was to characterize the incidence, clinical spectrum, risk factors and contribution to mortality of IRIS in two urban ART clinics in South Africa. Methods and Findings 498 adults initiating ART in Durban, South Africa were followed prospectively for 24 weeks. IRIS diagnosis was based on consensus expert opinion, and classified by mode of presentation (paradoxical worsening of known opportunistic infection [OI] or unmasking of subclinical disease). 114 patients (22.9%) developed IRIS (36% paradoxical, 64% unmasking). Mucocutaneous conditions accounted for 68% of IRIS events, mainly folliculitis, warts, genital ulcers and herpes zoster. Tuberculosis (TB) accounted for 25% of IRIS events. 18/135 (13.3%) patients with major pre-ART OIs (e.g. TB, cryptococcosis) developed paradoxical IRIS related to the same OI. Risk factors for this type of IRIS were baseline viral load >5.5 vs. <4.5 log10 (adjusted hazard ratio 7.23; 95% confidence interval 1.35–38.76) and ≤30 vs. >30 days of OI treatment prior to ART (2.66; 1.16–6.09). Unmasking IRIS related to major OIs occurred in 25/498 patients (5.0%), and risk factors for this type of IRIS were baseline C-reactive protein ≥25 vs. <25 mg/L (2.77; 1.31–5.85), haemoglobin <10 vs. >12 g/dL (3.36; 1.32–8.52), ≥10% vs. <10% weight loss prior to ART (2.31; 1.05–5.11) and mediastinal lymphadenopathy on pre-ART chest x-ray (9.15; 4.10–20.42). IRIS accounted for 6/25 (24%) deaths, 13/65 (20%) hospitalizations and 10/35 (29%) ART interruptions or discontinuations. Conclusion IRIS occurred in almost one quarter of patients initiating ART, and accounted for one quarter of deaths in the first 6 months. Priority strategies to reduce IRIS-associated morbidity and mortality in ART programmes include earlier ART initiation before onset of advanced immunodeficiency, improved pre-ART screening for TB and cryptococcal infection, optimization of OI therapy prior to ART initiation, more intensive clinical monitoring in initial weeks of ART, and education of health care workers and patients about IRIS.

Abstract
CONTEXT New trial data and drug regimens that have become available in the last 2 years warrant an update to guidelines for antiretroviral therapy (ART) in human immunodeficiency virus (HIV)-infected adults in resource-rich settings. OBJECTIVE To provide current recommendations for the treatment of adult HIV infection with ART and use of laboratory-monitoring tools. Guidelines include when to start therapy and with what drugs, monitoring for response and toxic effects, special considerations in therapy, and managing antiretroviral failure. DATA SOURCES, STUDY SELECTION, AND DATA EXTRACTION Data that had been published or presented in abstract form at scientific conferences in the past 2 years were systematically searched and reviewed by an International Antiviral Society-USA panel. The panel reviewed available evidence and formed recommendations by full panel consensus. DATA SYNTHESIS Treatment is recommended for all adults with HIV infection; the strength of the recommendation and the quality of the evidence increase with decreasing CD4 cell count and the presence of certain concurrent conditions. Recommended initial regimens include 2 nucleoside reverse transcriptase inhibitors (tenofovir/emtricitabine or abacavir/lamivudine) plus a nonnucleoside reverse transcriptase inhibitor (efavirenz), a ritonavir-boosted protease inhibitor (atazanavir or darunavir), or an integrase strand transfer inhibitor (raltegravir). Alternatives in each class are recommended for patients with or at risk of certain concurrent conditions. CD4 cell count and HIV-1 RNA level should be monitored, as should engagement in care, ART adherence, HIV drug resistance, and quality-of-care indicators. Reasons for regimen switching include virologic, immunologic, or clinical failure and drug toxicity or intolerance. Confirmed treatment failure should be addressed promptly and multiple factors considered. CONCLUSION New recommendations for HIV patient care include offering ART to all patients regardless of CD4 cell count, changes in therapeutic options, and modifications in the timing and choice of ART in the setting of opportunistic illnesses such as cryptococcal disease and tuberculosis.

Abstract
PURPOSE OF REVIEW HIV-associated multicentric Castleman disease (HIV MCD) is a rare lymphoproliferative disorder, the incidence of which appears to be increasing in the highly active antiretroviral therapy era. Current knowledge of the disease is limited and this review will discuss what is known about the pathophysiology, diagnosis, management, and prognosis of HIV MCD. RECENT FINDINGS HIV MCD has been shown to be associated with infection with human herpesvirus-8. Vascular endothelial growth factor and the cytokine interleukin-6 (IL-6) are also thought to play a role in the pathogenesis of MCD. Currently, rituximab is often used alone or in combination with chemotherapy for treatment of MCD. Novel monoclonal antibodies targeting IL-6 and the IL-6 receptor are also being studied for the management of this disease. SUMMARY Because HIV MCD is an uncommon diagnosis, comprehensive clinical studies have not been done, and understanding of the disease is incomplete. Further studies are needed to make definitive conclusions regarding optimal treatment of HIV MCD.

Abstract
BACKGROUND The search for a correlation between chemokine levels in plasma or serum and protection from HIV infection or progression to AIDS has been attempted by a number of workers. Chemokines are also suggested to play a role in immunity to Leishmania and Leishmania co-infection with HIV. OBJECTIVE To assess plasma level of alpha chemokine (CXCL12, formerly known as SDF-1alpha) and beta chemokines (CCL3, CCL4 and CCL5, formerly known as MIP-1alpha, MIP-1beta and RANTES, respectively) in HIV Visceral Leishmaniasis (VL) and HIV/VL coinfection. METHODS Frozen serum samples from a cross sectional study were used. The samples (n = 80) were comprised of healthy controls (n = 20), HIV patients (n = 20); Visceral Leishmaniasis (VL) patients (n = 22), and HIV/VL coinfected patients (n = 18). Chemokine levels of MIP-1alpha, MIP-1beta, RANTES, and SDF-1alpha of the serum samples were determined using ELISA. RESULTS MIP-1alpha and MIP-1beta expression were significantly elevated in Leishmania infected (p < 0.001) and in HIV/ VL co-infected individuals (p < 0.001) as compared to the control groups, while no significant difference was seen between HIV infected patients p > 0.05, implying that VL alone might modulate the production of these two chemokines in the case of co-infection In RANTES, however, its expression was significantly higher in HIV patients compared to controls (p = 0.002). Further assessment of serum RANTES concentration in HIV patients has shown a tendency of negative association with viral load. Higher amount of the alpha chemokine, SDF-1alpha, was detected in the HIV patients (p = 0.001) than the control group. Also a trend of positive association between SDF-1alpha and CD4 count was observed CONCLUSION From our data we can speculate that RANTES and SDF-1alpha might be involved in the regulation of HIV; and MIP-1alpha and MIP-1beta in VL. Therefore, enhancing or suppressing the production of these chemokines might help in therapeutic intervention of VL or HIV.

Abstract
A 24-year-old man was admitted with a 7-month history of non-productive cough, and recent onset of fever and progressive dyspnea. A chest X-ray film and computed tomography (CT) scan showed bilateral infiltrates that indicated pneumocystis pneumonia (PCP). A transbronchial lung biopsy specimen demonstrated Pneumocystis jirovecii infection on Grocott staining, and was positive for acid-fast bacilli without necrotizing granuloma, which indicated coinfection with both Pneumocystis jirovecii and Mycobacterium tuberculosis. A test for human immunodeficiency virus (HIV) infection was positive, and his CD4 + T-lymphocyte count was 92 cells per cubic millimeter. Chest CT findings and pathological findings.were atypical for active tuberculosis (TB). It is important that clinicians should be aware that HIV-infected patients may have concurrent pulmonary TB and PCP, because the diagnosis is difficult.

Abstract
A prospective, case-control study was undertaken to characterise seizures occurring in the context of human immunodeficiency type-1 (HIV-1) infection. Fifty consecutive patients with a documented seizure were enrolled along with fifty control patients. Among cases the median CD4 cell count was 8/mm3 and 84% had a prior AIDS defining illness; 14/mm3 and 80% among the control group. Generalised seizures were seen in 84%, partial with secondary generalisation in 10% and partial in 6%. Associated conditions included cerebral toxoplasmosis (22%), cryptococcal meningitis (8%), progressive multifocal leukoencephalopathy (6%), cytomegalovirus encephalitis (6%), central nervous system (CNS) lymphoma (2%), and other causes (14%) including pre-HIV epilepsy. No associated condition was identified in 42% of patients of whom 18% were receiving foscarnet therapy at the time of seizure, compared with 4% of control patients (p < 0.001). Concentrations of cerebrospinal fluid â2-microglobulin and neopterin, markers that have been associated with HIV-1 involvement of the CNS, were elevated in 12/12 and 13/13 patients, respectively, of the group with no identifiable cause for their seizure. We conclude that seizures occur principally in patients with advanced HIV-1 disease, with opportunistic infections of the CNS the predominant underlying condition. In the group with no identifiable cause foscarnet therapy and subclinical HIV-1 involvement of the CNS may be factors responsible for seizure activity.
