The diagnosis of cryptosporidiosis has been carried out using coprologic techniques in the Republic of Korea. However, antibody responses to Cryptosporidium have rarely been studied. Serum antibodies from HIV-positive/oocyst-positive Korean patients recognized significantly 31 and 27 kDa antigens, and HIV-negative/oocyst-positive individuals clearly reacted to 15/17 kDa antigens. Compared with oocyst-positive cases, 18.7% and 75.8% of sera from HIV-positive patients reacted to 31 and 27 kDa antigens. Only 11.1% of HIV-negative individuals reacted to 15/17 kDa. Based on these findings, serum antibody responses were different between HIV-positive and HIV-negative individuals infected with Cryptosporidium, and it is suggested that HIV-positive patients are more frequently exposed to C. parvum compared to HIV-negative individuals.

Background and Objectives: Globally, the human immunodeficiency virus (HIV) is responsible for one of the most serious pandemics to date. The vulnerability of the vestibular system in individuals with HIV has been confirmed, and central vestibular impairments have been frequently reported. However, there are disagreements on the impact of HIV on peripheral vestibular function. Thus, the current study aimed to determine the prevalence of peripheral vestibular impairment, specifically related to the semi-circular canals (SCCs), in HIV-positive individuals receiving antiretroviral (ARV) treatment. Subjects and Methods: A total of 92 adults between the ages of 18 and 50 years (divided into two groups) participated in the study. The first group comprised HIV-positive individuals receiving ARV treatment (n₁=60), and the second group comprised HIV-negative participants (n₂=32). The video head impulse test was used to conduct the head impulse paradigm (HIMP). Results: Bilateral normal HIMP results were obtained in 95% of the HIV-positive participants and all HIV-negative participants. The gain of the left posterior SCCs was significantly lower in the HIV-positive group, while the gains of all other canals between the two groups were comparable. Conclusions: The prevalence of peripheral vestibular impairment in the HIV-positive group was not significantly different from that of the HIV-negative group. The reduced prevalence in the current study may be attributed to participant characteristics, the test battery employed, and the central compensation of the vestibular dysfunctions at the later stages of infection.

It is believed that surgery on human immunodeficiency virus (HIV)-positive patients is dangerous and should be avoided due to the possibility of postoperative infection of the patients or HIV occupational transmission to the medical staff. We discuss here the preparations and measures needed to conduct surgery safely on HIV-positive patients, based on our experience. We performed sex reassignment surgery on two HIV-positive patients from January 2013 to January 2015. Both of them were receiving highly active antiretroviral therapy and were asymptomatic, with a normal CD4 count ($>500cells/{\mu}L$). The HIV-RNA was undetectable within the bloodstream. All the staff wore protective clothing, glasses, and three pairs of protective gloves in the operating room because of the possibility of transmission. Prophylactic antibiotics were administered to the patients, and antiviral therapy was performed during their perioperative course. Neither of the patients had postoperative complications, and none of the medical staff experienced accidental exposure. Both patients had satisfactory surgery outcomes without complications. HIV-positive patients can undergo surgery safely without increased risk of postoperative complications or HIV transmission to the staff through the proper use of antibiotics, active antiretroviral therapy, and supplemental protective measures with post-exposure prophylaxis for the staff in case of HIV exposure.

Individuals with human immunodeficiency virus (HIV) infection present with unique intraoral manifestations of various neoplasms. Intraoral HIV-associated Burkitt's lymphoma is a rare presentation, especially in patients of Indian origin and may present as an initial sign of HIV. The objective of this paper is to report a rare case of Burkitt's lymphoma in an HIV-positive Indian patient along with a special emphasis on differential diagnosis. A 30-year-old Indian female presented with a solitary, well-defined, exophytic mass extending anteroposteriorly and buccolingually from the 35th to 38th regions with no evidence of intraosseous extension. An incisional biopsy was performed, and histopathology showed sheets of neoplastic lymphoid cells with numerous tingible body macrophages with clear cytoplasm, presenting a starry sky appearance, suggesting a diagnosis of BL. The tumor cells were positive for CD10, CD20, c-myc, and Epstein-Barr virus, with a nearly 100% Ki-67 proliferative index. The patient tested positive for HIV. This report indicates the importance of immunohistochemical analysis to differentiate Burkitt's lymphoma from other similar lesions like diffuse large B-cell lymphoma. Thorough knowledge of the clinical presentation, etiopathogenesis, histopathology, and immunoprofile of intraoral HIV-associated Burkitt's lymphoma is essential among clinicians and pathologists.

In 2015, rapid human immunodeficiency virus (HIV) testing was implemented in all 25 public health centers in Seoul. During March and December 2015, 20,987 rapid HIV tests were performed, of which 116 (0.5%) were positive. Compared to those of the period before application of the rapid HIV test in place of conventional enzyme immunoassay method, the number of HIV tests performed and the number of positive results increased by sevenfold and twofold, respectively. In conclusion, expansion of the provision of rapid HIV tests in public health centers increased the number of voluntary HIV tests.

Purpose: Although long-term viral suppression and antiretroviral therapy (ART) success depend on sustained adherence, adolescents' adherence rates are suboptimal. Optimal adherence is influenced by various factors. Since Sub-Saharan Africa is home to over 80% of adolescents living with human immunodeficiency virus (HIV) and considering their unique characteristics and susceptibility to poor adherence, it is crucial to provide updated knowledge on adherence rates and their determinants among this population. This review aims to present up-to-date data on adherence rates and associated factors among HIV-positive adolescents in Sub-Saharan Africa. Methods: A systematic review was conducted following the PRISMA guidelines. The PubMed and Scopus databases were used to identify documents corresponding to the study's objectives. Eleven studies were included in this review after being selected from among all studies that were found online from 2017 to 2023. Results: The reported adherence rates ranged from 55% to 86%. In total, 32 factors were found to be related to adherence among HIV-positive adolescents in Sub-Saharan Africa. These included 12 adherence-facilitating factors and 20 adherence-inhibiting factors. The most often mentioned factors affecting adherence were advanced World Health Organization clinical stage (i.e., stage IV), ART dose and regimens, a lack of support, and violence victimization. Conclusion: Our findings can help healthcare providers collaborate with HIV-positive adolescents to improve ART adherence and ensure the best possible health outcomes.

Purpose: Infection with human immunodeficiency virus (HIV) remains a major global threat, and although the prevalence is comparatively still very low, the number of HIV-positive Koreans is increasing. However, there are no official guidelines as to how to treat people living with HIV/acquired immunodeficiency syndrome (AIDS) (PLWHA) or how to screen for potentially infectious people. This study assessed the level of knowledge and attitudes of dentists in Korea toward PLWHA, and their attitudes to screening patients for HIV infections. Methods: A cross-sectional prospective survey targeting dentists working in Korea was conducted using a self-administered questionnaire. Results: A satisfactory level of knowledge about HIV/AIDS and a relatively positive attitude toward PLWHA was found. Most of the respondents preferred rapid HIV testing using oral fluid as a specimen. The general attitude of dentists toward HIV/AIDS is sufficiently positive to enable provision of the best treatment to the patients in need. Conclusions: Most of the dentists require HIV testing in dental clinics. In spite of their needs, there are several obstacles. It is hoped that financial considerations and official legal requirements related to HIV testing strategies will be considered.

배 경: AIDS환자에게서 기회감염은 가장 치명적인 합병증으로 대부분은 폐 감염의 형태로 발현된다. 본 연구는 타 국가에 비해 아직까지는 유병률이 낮아서 상대적으로 자료가 부족한 국내의 현황에서, HIV 감염자 및 AIDS 환자의 임상양상을 살펴보고 특히 AIDS 환자들이 주로 어떤 호흡기 질환으로 발현하며, 호흡기 질환이 발현된 AIDS 환자와 기타 폐외 질환으로 발현하거나, HIV 단순감염자와의 임상상에 어떤 차이가 있는지를 중점적으로 살펴보고자 하였다. 방 법: 2001년부터 2006년 2월까지 중앙대학교 병원에 내원한 HIV 감염자 총28명을 대상으로, 이들 환자의 의무기록을 후향적으로 조사하여 분석하였다. 결 과: 총 28명의 HIV 감염자 중 27명이 남자이었고 평균연령은 40.6세로 30대가 40%로 가장 많은 분포를 보였다. 이 중에서 폐질환을 동반한 경우가 11명이었고, 폐외질환 환자가 16명이었다. 폐질환을 동반환 환자군과 폐외질환자에서 내원시 CD4+림프구수와 HIV RNA 수는 평균 79.5/mm3, 48,903 IU/ml, $400/mm^3$, 60,256 IU/ml을 보여(P value: 0.001, 0.695) 폐감염이 동반된 경우에 더 심한 면역억제 상태가 심하였다. 폐감염의 종류로는 폐결핵, 주폐포자충 폐렴이 가장 많은 빈도를 차지하였으며, 이들의 평균 CD4+림프구 수를 보면, 폐결핵이 $56/mm^3$, 주폐포자충폐렴이 $42/mm^3$이었다. 결 론: HIV에 관련된 폐질환이 동반된 경우 그렇지 않은 경우에 비해 월등히 면역억제가 심하였다. 이 중에서 폐결핵과 주폐포포자충 폐렴이 가장 흔한 형태의 폐감염이었다. 본 연구는 일개 대학병원에서 경험한 HIV 감염자와 특히 폐질환이 발현된 AIDS 환자의 임상상의 특징을 확인할 수 있었고 빠른 조기진단과 치료의 필요성을 다시 한번 확인하였다.
