Promoting Well-being Among Informal Caregivers of People With HIV/AIDS in Rural Malawi: Community-Based Participatory Research Approach.

BACKGROUND: People living with HIV/AIDS and their informal caregivers (usually family members) in Malawi do not have adequate access to patient-centered care, particularly in remote rural areas of the country because of the high burden of HIV/AIDS, coupled with a fragmented and patchy health care system. Chronic conditions require self-care strategies, which are now promoted in both developed and developing contexts but are still only emerging in sub-Saharan African countries. OBJECTIVE: This study aims to explore the effects of the implementation of a short-term intervention aimed at supporting informal caregivers of people living with HIV/AIDS in Malawi in their caring role and improving their well-being. The intervention includes the dissemination of 6 health advisory messages on topics related to the management of HIV/AIDS over a period of 6 months, via the WhatsApp audio function to 94 caregivers attending peer support groups in the rural area of Namwera. METHODS: We adopted a community-based participatory research approach, whereby the health advisory messages were designed and formulated in collaboration with informal caregivers, local medical physicians, social care workers, and community chiefs and informed by prior discussions with informal caregivers. Feedback on the quality, relevance, and applicability of the messages was gathered via individual interviews with the caregivers. RESULTS: The results showed that the messages were widely disseminated beyond the support groups via word of mouth and highlighted a very high level of adoption of the advice contained in the messages by caregivers, who reported immediate (short-term) and long-term self-assessed benefits for themselves, their families, and their local communities. CONCLUSIONS: This study offers a novel perspective on how to combine community-based participatory research with a cost-effective, health-oriented informational intervention that can be implemented to support effective HIV/AIDS self-care and facilitate informal caregivers' role.

Immune indices and oral health in patients infected with the human immunodeficiency virus.

BACKGROUND: The human immunodeficiency virus (HIV) is the causative agent of acquired immunodeficiency syndrome (AIDS). During the incubation period of AIDS, oral manifestations may precede systemic symptoms; therefore, it is vitally important to explore the relationship between HIV and oral health and other indicators. This study aimed to further assess the correlation between demographic risk factors, the dental health of HIV-infected patients, and the correlation of oral health indicators with CD4+ T-cell counts (CTCCs) and HIV viral loads (HIV-VLs). METHODS: Demographic data on 108 HIV-infected patients were first recorded by questionnaire from March 2016 to November 2018. Patients' dental health and oral lesions were assessed by a dental specialist; in addition, they were tested for CTCCs and HIV-VLs by flow cytometry and NucliSENS EasyQ® HIV-1 virometer. Finally, the links between CTCC, HIV-VL, and the dental health (including oral lesions) of the patients were analyzed. RESULTS: We found that age, marital status, and body mass index (BMI) were relevant to the patient's dental health (P < 0.05) and that their oral hygiene was relevant to their dental health (P < 0.05). However, HIV-VL was not directly related to periodontal/dental clinical indicators (P > 0.05). We discovered that the oral lesions in HIV-infected patients were related to decreased CTCCs and increased HIV-VLs (P < 0.05). CONCLUSIONS: We concluded that HIV-infected patients with severely impaired immune function tend to have poor dental health. Moreover, the prevalence of oral lesions was negatively correlated with CTCC and positively correlated with HIV-VL.

Navigating the healthcare system in Nairobi City County: perspectives and experiences in the utilization of oral healthcare by caregivers of children with HIV/AIDS.

BACKGROUND: The healthcare system in any republic can cause inequalities in health outcomes if they do not take into account the needs of deprived populations. Children with HIV/AIDS are known to have a high vulnerability to oral diseases; yet, they continue to face limitations in the utilization of oral healthcare. While other determinants of healthcare utilization may co-exist, possible gaps in the oral healthcare system can collectively affect a vulnerable group disproportionately in the utilization of oral healthcare. OBJECTIVE: To explore qualitatively, the perspectives, experiences and attributions of a cohort of caregivers of children with HIV/AIDS and their Health Care Providers (HCPs), on the utilization of oral healthcare within the structure of the oral healthcare system in Nairobi City County (NCC). DESIGN: A cross-sectional explorative mixed methods study design of two hundred and twenty one (221) female caregivers of children with HIV/AIDS and their HCPs using a survey, Focus Group Discussions (FGDs) and In-depth Interviews (IDIs). The study setting was the HIV-Care Facilities (HIV-CCFs) at three large hospitals in NCC. RESULTS: Caregivers mainly utilized independent 'nearby' private dental clinics for oral healthcare services, attributing their selection to cheaper user-fees, proximal service location, and recommendations from social networks. Wait time, opening and closing hours, health workers' attitudes and inferred opportunity costs were perceived as important quality issues in the utilization of oral healthcare. CONCLUSION: The oral healthcare system in NCC does not support the utilization of oral healthcare within the context of providing comprehensive healthcare for children with HIV/AIDS. Absence of 'in-house' oral health services at the HIV- CCFs is viewed as a defining structural barrier.

Total mouth photodynamic therapy mediated by red LED and porphyrin in individuals with AIDS.

Due to the immune changes resulting from HIV/AIDS infection, systemic and local infections throughout the body are common. The use of high activity antiretroviral therapy has been widely used during treatment, which, added to the use of antibiotics, antifungals, and the patients' own immunocompromised state, cause important changes in the oral microbiota. The emergence of pathological microorganisms and with high resistance to drug therapies are frequent and cause serious damage to the oral health of these patients. In this sense, antimicrobial photodynamic therapy (aPDT) appears as a promising alternative in the control of these oral infections. The aim of the study was to test the effectiveness of a therapeutic protocol for total oral aPDT mediated by a 660-nm red LED (light-emitting diode) associated with porphyrin in individuals with AIDS. Patients were selected by exclusion criteria and randomly distributed into groups to test the effectiveness of antimicrobial aPDT with 50 µg/ml porphyrin associated with the red LED. Before and after the treatments, saliva samples were collected and processed in duplicate in selective culture media. Colonies were counted and the results obtained in Log10 CFU/ml and tested statistically. It was concluded that aPDT was effective in reducing oral enterobacteria, in addition to reducing Streptococcus spp. and general count of microorganisms, when considering the numbers of TCD4 and TCD8 lymphocytes.

Oral symptoms and oral hygiene behaviours among patients with type 2 diabetes at a hospital in Japan: A cross-sectional study.

OBJECTIVES: Effective daily oral hygiene behaviour will prevent periodontal disease. This study aimed to examine the oral symptoms, oral hygiene behaviours and factors contributing to oral hygiene behaviours among patients with type 2 diabetes in a hospital in Japan. METHODS: A cross-sectional survey was conducted with 198 patients with type 2 diabetes. Oral symptoms were assessed using a dichotomous scale based on clinical guidelines. Oral hygiene behaviours were assessed based on the frequency of daily tooth brushing and the use of interdental cleaning aids. Chi-square tests and logistic regression analyses were also performed. RESULTS: Overall, 71.2% of the participants had oral symptoms. Of the participants, 80.3% performed twice daily tooth brushing and 61.1% did not perform interdental cleaning on a daily basis. Logistic regression analysis revealed that tooth brushing behaviour was negatively associated with male patients (odds ratio [OR] = 0.45, 95% confidence interval [CI]: 0.25-0.80), difficulty with mastication (OR = 0.63, CI: 0.43-0.92) and tooth loss (OR = 0.68, CI: 0.46-1.00) and positively associated with periodontal disease (OR = 1.73, CI: 1.10-2.72). There were no significant variables related to the use of interdental cleaning aids. CONCLUSIONS: Patients need to learn about the necessity for regular oral hygiene behaviours and the appropriate way. In particular, support for male patients, those who have difficulty with mastication, those who have experienced natural tooth loss, and those who have not been diagnosed with periodontal disease are needed.

Students' preferences regarding teaching methodology in dental education - a cross-sectional study.

INTRODUCTION: The goal of dental education is to prepare competent ethical professionals with critical thinking, reasoning and analyzing skills along with ability of application of clinical skills and judgement in treating a patient. The present study was designed with the objective to elicit the preferences of dental students regarding the utility of the prevailing teaching and learning methods and teaching aids. MATERIAL AND METHODS: A cross-sectional study was conducted among undergraduate dental students. Study population consisted of 382 dental students. A self-designed close-ended questionnaire written in English was constructed specifically for the study. The questionnaire was divided into two sections. Information regarding various teaching and learning methods both in theory and practical/clinical classes was obtained from the students. Results were calculated using numbers and percentages only. RESULTS: The mean age of the students was 20.49 + 2.4 years. Problem based learning (PBL) was rated very useful by 76% (290) and useful by 24% (92) of subjects. Performing clinical/practical procedure individually rather than in group was rated very useful by 31% (118) of subjects. Use of power-point along with the blackboard was rated as the most useful method by 95% (363) of subjects. Majority of subjects (61%, 233) felt that 40 minutes duration of lecture was more useful as compared to 30 minutes. CONCLUSIONS: Our study concludes that dental students prefer active teaching learning methodologies and combination of audiovisual aids. Hence it is suggested that collaboration of different active teaching methods and aids should be adopted by the teachers in order to enhance the student learning process.

Facteurs associés aux attitudes discriminatoires des chirurgiens-dentistes vis-à-vis des personnes vivant avec le VIH en Côte d'Ivoire.

OBJECTIVES: Discriminatory attitudes (DA) of dental surgeons towards PLWHIV may hinder their access to oral health care. The objective of this study was to identify the factors associated with the discriminatory attitudes of dentists towards PLHIV in Côte d’Ivoire. METHODS: This was a cross-sectional study conducted on a randomly selected sample of dentists in Abidjan. The data collected were: their socio-professional characteristics, their knowledge of HIV/AIDS, their perceptions and attitudes towards PLWHIV, and whether they had received continuing education or sensitization on HIV/AIDS. Discriminatory attitudes was a binary variable, defined from the combination of four criteria. Numbers and percentages were calculated for all variables. The risk of having DA was estimated by the odds ratio. RESULTS: A total of 120 dentists were surveyed, 43.3% of whom were women and 39.2% from the private sector. They did not know the routes of transmission (29.2%) and the oral pathologies associated with HIV (62.5%). Their perceptions were dominated by the fear of being contaminated during care (69.2%). The frequency of DA was estimated at 69.2%. The main associated factors were: female gender; lack of knowledge of HIV/AIDS-related oral pathologies, lack of the risk of HIV transmission after blood exposure accident, and ignorance of the existence of a law on the protection of PLWHA; and fear of being contaminated. CONCLUSION: This study reveals that the DA of dental surgeons with regard to PLWHIV in Côte d’Ivoire are mainly the result of poor knowledge of the disease.

Infections at the nexus of metabolic-associated fatty liver disease.

Metabolic-associated fatty liver disease (MAFLD) is a chronic liver disease that affects about a quarter of the world population. MAFLD encompasses different disease stadia ranging from isolated liver steatosis to non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis and hepatocellular carcinoma. Although MAFLD is considered as the hepatic manifestation of the metabolic syndrome, multiple concomitant disease-potentiating factors can accelerate disease progression. Among these risk factors are diet, lifestyle, genetic traits, intake of steatogenic drugs, male gender and particular infections. Although infections often outweigh the development of fatty liver disease, pre-existing MAFLD could be triggered to progress towards more severe disease stadia. These combined disease cases might be underreported because of the high prevalence of both MAFLD and infectious diseases that can promote or exacerbate fatty liver disease development. In this review, we portray the molecular and cellular mechanisms by which the most relevant viral, bacterial and parasitic infections influence the progression of fatty liver disease and steatohepatitis. We focus in particular on how infectious diseases, including coronavirus disease-19, hepatitis C, acquired immunodeficiency syndrome, peptic ulcer and periodontitis, exacerbate MAFLD. We specifically underscore the synergistic effects of these infections with other MAFLD-promoting factors.

Oral health and HIV: What dental students need to know.

INTRODUCTION: Dentists have an important role in reducing new HIV infections by early diagnosis and need to know how to treat patients with HIV and understand universal cross-infection control. In many parts of the world, healthcare professionals struggle to provide care because of barriers including stigma and cultural attitudes. AIM: To investigate the effectiveness of a brief educational intervention in understanding/changing the views of dental school deans regarding the quality of the oral health and HIV/AIDS teaching and their willingness to undertake a curriculum review if appropriate. METHODS: Questionnaires before and after interactive presentation to the deans of 30 Indonesian dental schools and discussion. RESULTS: Only six of 30 dental school deans believed that their HIV undergraduate dental student teaching was inadequate before the intervention, but 29 of 30 deans recognised the need to review their curriculum after the intervention. Whilst the majority (24/30) felt that their HIV teaching was adequate, good or excellent, the majority also thought that their students would find it difficult to treat patients with HIV. CONCLUSION: The brief educational intervention was effective in improving the understanding/changing the views of dental school deans regarding the quality of HIV/AIDS teaching and learning at their own institution and engaging a willingness to undertake curriculum review.

The role of patient and public involvement in oral health and HIV/AIDS research, practice and policy.

Patient and public involvement (PPI) is a process whereby patients, caregivers, service users and other relevant stakeholders, including the general public, are actively involved and engaged in activities to develop research. The dental research agenda has traditionally been driven by clinicians, where patients and the public have participated in research as subjects; patient and public involvement can contribute to the research agenda including the design and conduct of research by providing unique perspectives gained through lived experience. This panel of the 8th World Workshop on Oral Health and Diseases in AIDS considered the role of people living with HIV (PLHIV) to contribute to oral health and HIV research and policy through a process of involvement and empowerment. The panel introduced the concepts of PPI, described the purpose of PPI, reflected upon the logistic and ethical considerations thereof and considered how PPI had been utilised effectively in HIV research and policy change. The audience discussion focused on ways in which PPI could more readily and consistently be encouraged within oral health research involving PLHIV.

Virulence properties and sensitivity profile of Candida parapsilosis complex species and Kodamaea ohmeri isolates from onychomycosis of HIV/AIDS patients.

Cutaneous fungal infections include onychomycosis, an infection of the nail that affects both healthy and immunocompromised patients. This study investigated the in vitro hydrolytic enzymes production, adhesion and biofilm formation capacity of Candida parapsilosis complex species and Kodamaea ohmeri isolates from onychomycoses of HIV/AIDS patients and also established the antifungal sensitivity profiles of these isolates. Onychomycosis in HIV/AIDS patients showed a high prevalence of emerging yeasts, among which C. parapsilosis complex species and K. ohmeri were the most frequent. Three C. parapsilosis sensu stricto and two C. orthopsilosis isolates were resistant to amphotericin B and 83% of isolates were resistant to terbinafine. All three different species evaluated were proteinase and hemolysin producers. All isolates adhered to stainless steel and siliconized latex surfaces, and carbohydrates intensified adhesion of all isolates. Isolates adhered to keratinous nail and 50% formed biofilms with strong intensity. In multispecies or polymicrobial biofilms, C. albicans and Staphylococcus aureus regulated the biofilm formation of the analyzed species, decreasing the number of their cells in biofilms. The isolation of emerging yeast species from onychomycosis which are great producers of hydrolytic enzymes and with high adhesion and biofilm formation capacity is a result that should be considered relevant in clinical practice. In addition, half of the isolates was resistant to at least one of the tested antifungals. Taken together these data corroborate the infectious capacity and viability of these isolates under favorable conditions.

Common oral opportunistic infections in Human Immunodeficiency Virus infection/Acquired Immunodeficiency Syndrome: Changing epidemiology; diagnostic criteria and methods; management protocols.

There were 36.9 million in the world living with human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) as of 2017, and new infections have seen a reduction by 18% since 2010. But this rate of decline is not sufficient for the goal of eradication of AIDS by 2030. Only 21.7  million people infected with HIV have accesses to antiretroviral therapy, with the rest at risk of the potential complications of HIV infection. It has been shown that oral lesions are diagnostic and prognostic of HIV infection, and many oral opportunistic infections continue to be a major problem, particularly in developing countries. It is therefore important that dental surgeons be aware and updated to recognize and manage the oral effects of HIV infection/AIDS. This chapter describes the classification, diagnosis, and management of oral lesions in these patients, based on our current understanding of the infection. This review also discusses the standardization of diagnosis of oral lesions in HIV infection/AIDS patients, immune reconstitution inflammatory syndrome case definition, and the research priorities formulated at the 7th World Workshop on Oral Health and Disease in AIDS.

Primary cutaneous actinomycosis: a diagnosis consideration in people living with HIV/AIDS.

BACKGROUND: Owing to similar clinical presentations, as of cutaneous disease of different etiologies, and extreme rarity in the global incidence; primary cutaneous actinomycosis often remains as diagnostic challenges. CASE PRESENTATION: Herein, we describe a case of primary cutaneous actinomycosis, erroneously treated as cutaneous tuberculosis, in a patient living with AIDS. On clinical examination, the characteristic lesion, resembling cutaneous tuberculosis, observed on the dorsum of a left leg. No other lesion elsewhere on the body was observed, however. Cytological examinations of the stabbed biopsy were negative for malignant cells; although hyper-keratosis and mild-acanthosis of epidermis, acute inflammatory infiltrates comprising plasma cell, macrophages and neutrophils were observed in the upper and mid dermis. The pus aspirated from lesion grew a molar tooth, adherent colonies in microaerophilic condition. Further, identifications and susceptibility pattern against recommended antibiotics were assessed as per the CLSI (Clinical and Laboratory Standard Institute) guidelines. Subsequently, the case was then, diagnosed as primary cutaneous actinomycosis. Radiographic imaging of abdomen and lungs were normal; no feature of disseminated actinomycosis seen. Penicillin G followed by Penicillin V, was prescribed for 12 months. The patient underwent progressive changes and no relapse noted on periodic follow-up. CONCLUSION: The case underscores cutaneous actinomycosis requires a diagnosis consideration, especially in People Living with HIV/AIDS (PLHA), where myriad of opportunistic cutaneous infections are common.

Evaluation of dental students' knowledge and patient care towards HIV/AIDS individuals.

PURPOSE: The aim was to evaluate the knowledge of the students of dental students regarding patients care towards HIV positive individuals. METHODS: Two hundred and eighty-three dental students (pre-clinical, n = 45; clinical, n = 238) answered an electronic questionnaire, approaching biosafety procedures, oral manifestations of AIDS and knowledge of HIV infection. Data were present as an average from findings from students of nine different semesters, grouping them by pre-clinical (1-4) and clinical (5-9) semesters, from two different university campuses. Furthermore, data were analysed using the t test and chi-square test. RESULTS: Students' mean age was 24 years. Amongst 14 oral manifestations questioned, Kaposi sarcoma, oral candidiasis, necrotizing ulcerative gingivitis and herpes simplex were more associated with HIV. Over 90% of the respondents would be concerned about becoming infected with HIV after a needle stick injury and were willing to be tested for HIV; know that HIV/AIDS patients can contaminate dental care professionals, that needle perforation can transmit HIV, and that medical professionals are more prone to cross-contamination. Regarding the use of physical barrier, almost all participants use disposable mask, goggles, cap and procedure gloves with all patients; the use of disposable lab coat and two pairs of gloves were the least used with all patients. CONCLUSIONS: Participating students have good knowledge on biosafety in the management of HIV/AIDS patients, as well as on the most commonly associated oral manifestations. However, there is a need for improvement on some topics related to HIV/AIDS, especially regarding less known oral lesions, and HIV diagnostic tests.

Assessment of knowledge level about acquired immune deficiency syndrome and patient approaches of dental students.

BACKGROUND: The aim of this study was to evaluate the level of knowledge about HIV, and intraoral signs that can be seen in HIV positive patients and the interpretation of attitudes toward HIV positive patients of fourth- and fifth-grade students at Marmara University Faculty of Dentistry, Istanbul, Turkey. MATERIAL AND METHODS: In our study, a questionnaire consisting of 23 questions was applied to 100 fourth- and 100 fifth-grade students totalling 200 dental students who are educated in Marmara University Faculty of Dentistry. Besides the knowledge level of the students, their attitudes were evaluated using the survey conducted. Chi-square (or Fisher's exact test at appropriate locations) was used to examine the relationship between categorical variables. Statistical significance level was determined as P < 0.05. RESULTS: Of the 200 participants, 46 (23.0%) were males and 154 (77.0%) were females. One hundred people (50%) are fourth grade, 100 people (50%) are fifth grade. The rate of fifth grade agreements for the question "Treatment of HIV positive patient increases the risk of transmission of HIV infection to dentist" was statistically higher than that of fourth-grade students (Fisher's exact P < 0,05). Fifth-grade knowledge of oral symptoms of HIV/AIDS was statistically higher than fourth grades (Fisher's exact P < 0.05). CONCLUSION: As the grade level increases, the knowledge about HIV/AIDS raises portraying a relevant approach to patients with AIDS. Comprehensive training and motivation for improving dentistry students' awareness against HIV-positive patients will also improve knowledge and attitudes of the students that enable them to take better care of HIV-positive patients.

Knowledge, Attitude and Practice of Dental Students Regarding Treatment of Patients with HIV or AIDS in Nepal.

Background There have been discrepancies in providing treatment to HIV positive patients across healthcare fields, due to lack of knowledge. Currently, there is an increasing awareness of discrepancies in the provision of dental care for HIV positive patients and a potential relationship to health care professional knowledge and attitudes towards these individuals. Objective To analyze dental students' knowledge, attitudes and practices regarding treatment of HIV patients in Nepal. Method An online survey was sent to all dental students via blue-eval. Mixed effects logistic regression was used to predict a likelihood of the dental treatments between HIV negative and HIV Positive patients. Logistic regression was used to predict the likelihood of dental treatments for HIV patients based on the knowledge of human immunodeficiency virus. Result Two hundred six students (65%) responded to the survey from dental colleges in Nepal. All students had worked with at least one HIV positive patient. Overall, students felt uncomfortable providing dental treatments to HIV positive patients, with only 29% likely to perform a prophylaxis and filling, 18% orthodontic treatment, 16% endodontic treatment, 12% periodontal scaling, and only 10% extractions. Conclusion Currently dental students in Nepal are uncomfortable in providing treatment to HIV/ AIDS patients.

Intra-arterial spread of Mucormycetes mediates early ischemic necrosis of brain and suggests new venues for prophylactic therapy.

Intracranial invasion by Mucormycosis carries high mortality mostly related to arterial occlusion and ischemic necrosis. We report clinical, imaging and autopsy findings in an adult immunodeficiency syndrome (AIDS) patient with fungal infection extending from a tooth. We report a striking discordance between a restriction of fungal growth to the initial branches of the circle of Willis and extensive ischemic infarcts of deep brain structures. This lends to a suggestion of apparently lost opportunities for brain salvage and prompts a re-assessment of clinical approaches to treat mucormycosis.

Surface modified kokum butter lipid nanoparticles for the brain targeted delivery of nevirapine.

AIM: The present work investigates the efficacy of Polysorbate 80(P80) coated Kokum butter (KB) solid lipid nanoparticles (P80NvKLNs) for the brain targeted delivery of Nevirapine (Nv). METHODS: Solid lipid nanoparticles (SLNs) were prepared by nanoprecipitation technique and evaluated for drug excipient compatibility studies, z- average particle size (nm), zeta potential (mv), percentage drug entrapment efficiency (%EE), surface morphology and in-vitro drug release properties. The in-vivo biodistribution and brain targeting efficiency of nanoparticles were studied in healthy male Wistar rat (150-200 g). RESULTS: P80NvKLNs were found to be smooth surfaced, spherical shaped having average particle size of 177.80 ± 0.82 nm, zeta potential of -8.91 ± 4.36 mv and %EE of 31.32 ± 0.42%. P80NvKLNs remained in blood circulation for 48 h maintaining a sustained release in brain for 24 h (p < 0.05). CONCLUSION: The study proves the efficacy of Polysorbate 80 coated Kokum butter nanoparticles for brain-targeted delivery of drugs providing ample opportunities for further study.

[Profile of Kaposi sarcoma patients in the competence network HIV/AIDS]. / Profil der Kaposi-Sarkom-Patienten im Kompetenznetz HIV/AIDS.

BACKGROUND: Kaposi's sarcoma (KS) represents the most common AIDS-defining neoplasm. Only very few studies regarding the course and treatment of human immunodeficiency virus (HIV)-associated KS have been carried out in Germany. OBJECTIVE: In this study the course of HIV-associated KS was observed in patients from the cohort database of the competence network for HIV/AIDS. MATERIAL AND METHODS: Data from HIV-associated KS patients from 9 German core centers from 1987 to 2011 were retrospectively collected. Kaplan-Meier curves for the recurrence and survival probability were calculated. RESULTS: In 222 patients KS was diagnosed at a median age of 38.5 ± 10.1 years. Men were almost exclusively affected (97.7%). The HIV viral load at the time of diagnosis was in 7.4% <50 copies/ml. Of the patients 55.5% developed KS with a CD4 cell count of <200 cells/µl and 9.5% with >500 cells/µl. In 68 patients KS therapy consisted exclusively of the optimization or initiation of antiretroviral therapy (ART). In addition, 71 patients were treated with pegylated liposomal doxorubicin. During the median follow-up period of 8.9 ± 4.9 years, 80.2% of the patients were free of KS recurrence. Survival rates after 5 and 10 years were 96.8% and 91.3%, respectively. CONCLUSION: Even with a good immune status HIV-associated KS occurred. An effective ART was the most important mainstay of therapy. With appropriate therapy, HIV-positive patients with KS showed a good survival rate.

Diversity of human herpesvirus 8 genotypes in patients with AIDS and non-AIDS associated Kaposi's sarcoma, Castleman's disease and primary effusion lymphoma in Argentina.

HHV-8 genotypes are distributed heterogeneously worldwide. The variable K1 gene and the conserved ORF26E region serve to genotype. The aim of the study was to characterize HHV-8 isolates from patients with AIDS, classical, and iatrogenic KS, primary effusion lymphoma and Castleman's disease and one organ donor from Argentina by analysis of ORFK1 and ORF26E regions. DNA was extracted from fresh or paraffin embedded biopsies, blood, and saliva samples and submitted to HHV-8 PCR. Phylogenetic analyses of ORFK1 showed that subtypes C (C1, C2, and C3), B1 and A (A1, A2, and A3) were present in 70.8%, 16.7%, and 12.5% of cases, respectively. Analyses of ORF26E fragment revealed that most strains (45.8%) were subtype A/C while the remaining fall into K, J, B2, R, and D subtypes. Linkage between ORFK1-ORF26E subtypes corresponded to reported relationships, except for one strain that clustered with B1 (K1 African) and D (ORF26E Asian-Pacific) subtypes. This research reveals predominance of subtype C, a broad spectrum of HHV-8 genotypes and reports the first isolation of the African B genotype in Argentina.
