Potential role of the melanocortin signaling system interference in the excess weight gain associated to some antiretroviral drugs in people living with HIV

Combined antiretroviral therapy (cART) increased the life expectancy of people living with HIV (PLHIV) and remarkably reduced the morbidity and mortality associated with HIV infection. However, non-AIDS associated comorbidities including diabetes, hypertension, hyperlipidemia, and cardiovascular diseases (CVD) are increasingly reported among PLHIV receiving cART. Killer cell immunoglobulin receptors (KIRs) expressed on the surface of natural killer (NK) cells have been previously implicated in controlling HIV disease progression. The aim of this study is to investigate the role of KIRs in developing non-AIDS associated comorbidities among PLHIV. Demographic and behavioral data were collected from voluntary participants using a standardized questionnaire. Whole blood samples were collected for KIR genotyping. Hypertension (29.5%) and hyperlipidemia (29.5%) followed by diabetes (23.7%) and CVD (9.7%) were mainly reported among our study participants with higher rate of comorbid conditions observed among participants > 40 years old. The observed KIR frequency (OF) was ≥90% for inhibitory KIR2DL1 and KIR3DL1, activating KIR2DS4 and the pseudogene KIR2DP1 among study participants. We detected significant differences in the expression of KIR3DS4 and KIR3DL1 ( p = 0.038 ) between diabetic and nondiabetic and in the expression of KIR2DL3 between hypertensive and normotensive HIV-infected individuals ( p = 0.047 ). Moreover, KIR2DL1 and KIR2DP1 were associated with significantly reduced odds of having CVD (OR 0.08; 95% CI: 0.01-0.69; p = 0.022 ). Our study suggests the potential role of KIR in predisposition to non-AIDS comorbidities among PLHIV and underscores the need for more studies to further elucidate the role of KIRs in this population.

Abstract (1) Background: HIV-associated neurocognitive disorders (HAND) can occur as a result of HIV-mediated neuroinflammation and affect people living with HIV (PWH) despite advances in combination antiretroviral therapy (cART). Brain macrophages have been implicated as a source of virus and neurotoxic factors. In this study, we examined the potential role of the immunophilin ligands rapamycin and FK506 in modulating neuroinflammation caused by infected macrophages. (2) Methods: Monocytes were isolated from blood samples from three different blood donors and were differentiated into macrophages (MDMs). These cells were subsequently infected with HIV and treated with combinations of an antiretroviral (ARV) cocktail (raltegravir, emtricitabine, and tenofovir), FK506, and rapamycin. Immunocytochemistry and RT-qPCR were used to analyze the phagocytosis of amyloid beta and the expression of macrophage phenotype-associated markers such as Iba1, TREM2, and IL-6. Viral replication was measured using p24 ELISA. (3) Results: Viral replication among infected MDMs as indicated by p24 levels was positively correlated with Iba1 levels and negatively correlated with IL-6 expression. However, infected MDMs showed lower Iba1 levels than non-infected cells. Rapamycin treatment appeared to lower p24 levels across all donors. Phagocytosis was associated with higher Iba1 levels and was impaired in rapamycin-treated MDMs. (4) Conclusions: Rapamycin seemed to protect against viral replication. However, decreased replication was correlated with a decrease in phagocytic activity. Iba1 may be involved in phagocytosis and HIV infection while IL-6 appeared to indicate protective effects against replication.

Kaposi sarcoma (KS) is a mesenchymal tumour caused by KS-associated herpesvirus and is an AIDS-defining illness. Despite a decline in incidence since the introduction of combination anti-retroviral therapy, KS remains the most common cancer in people living with HIV in sub-Saharan Africa, where it causes significant morbidity and mortality. This review reflects on recent epidemiological data as well as current management, unmet needs and future perspectives in the treatment of HIV-associated KS with particular emphasis on the potential role of immune checkpoint inhibitors.

Abstract : Indicator of the health welfare through Sustanable Development Goals (SDGs) is to reduce the incidence of HIV-AIDS, decrease the rate of the epidemic and maintain the quality of life of people living with HIV-AIDS (PLWHA). Trend cases of HIV-AIDS is the most recent spread among people, especially housewives. In Malang until 2015 found 278 Housewife of 409 cases of AIDS. The prevalence of HIV-AIDS in Malang Regency is ranked second after Surabaya city in East Java. For the importance of public participation and citizen care AIDS Cahaya Care Turen take responsibility for the condition. Determination Rule Goverment number 2 2015 year on the Participation of the community response to HIV-AIDS in Malang as a legal rule. Concerned Citizens activities AIDS (WPA). WPA Cahaya Care Turen is increases HIV risk and quality of life PLWHA. The purpose of this study was to determine the role of Citizens AIDS Cahaya Care Quality of Care Turen against people living with HIV in Puskesmas Turen Malang. The study design using a quasi-experimental, with purposive sampling using a sampling technique. Total number of research subjects 23. Based on test results obtained with the Wilcoxon p value <0.005, which means that there is a significant difference before and after PLWHA joining participated in the WPA Cahaya Care Turen. The conclusion of this study is WPA activities involving people living with HIV and at risk groups can optimize compliance with antiretroviral drugs that have an impact on improving the quality of life of PLHIV. Suggestions in this research is done WPA Program activities are structured and ongoing cross-sector in order to improve the quality of life and empower PLWHA.Keywords : WPA Cahaya Care Turen, Quality of life, PLWHA Abstrak : Salah satu indikator kesejahteraan kesehatan melalui Sustanable Development Goals (SDGs) adalah menekan angka kejadian HIV-AIDS, menurunkan laju epidemik dan mempertahankan kualitas hidup Orang dengan HIV-AIDS (ODHA). Trend kasus HIV-AIDS terkini terbanyak adalah menjangkit dikalangan masyarakat khususnya pada ibu rumah tangga. Kabupaten Malang sampai dengan tahun 2015 ditemukan 278 Ibu Rumah Tangga dari 409 kasus AIDS. Prevalensi HIV-AIDS di Kabupaten Malang ini merupakan peringkat kedua di Jawa Timur setelah Kota Surabaya. Untuk itu pentingnya peran serta masyarakat dan warga peduli AIDS Cahaya Care Turen ikut bertanggung jawab terhadap kondisi tersebut. Penetapan Peraturan Bupati Malang no.2 th.2015 tentang Peran serta masyarakat penanggulangan HIV-AIDS di Kabupaten Malang diharapkan dapat mengurangi risiko penularan HIV dan meningkatkan kualitas hidup ODHA. Tujuan dari penelitian ini adalah untuk mengetahui Peran Warga Peduli AIDS Cahaya Care Turen terhadap Kualitas ODHA Di Wilayah Kerja Puskesmas Turen Kabupaten Malang. Desain penelitian menggunakan quasi eksperimen, dengan teknik sampling menggunakan purposive sampling. Jumlah subyek penelitian sejumlah 23. Berdasarkan hasil uji dengan Wilcoxon didapatkan nilai p value < 0.005 yang berarti bahwa terdapat perbedaan bermakna sebelum dan sesudah ODHA bergabung mengikuti kegiatan WPA Cahaya Care Turen. Kesimpulan dalam penelitian ini adalah kegiatan WPA dengan melibatkan ODHA dan kelompok beresiko dapat mengoptimalkan kepatuhan obat ART sehingga berdampak terhadap peningkatan kualitas hidup ODHA. Saran dalam penelitian ini adalah dilakukannya Program kegiatan WPA yang terstruktur dan berkesinambungan lintas sektor guna meningkatkan kualitas hidup dan memberdayakan ODHA.

Target Effects

Antiretroviral drugs have dramatically improved the morbidity and mortality of people living with HIV (PLWH). While current antiretroviral therapy (ART) regimens are generally well-tolerated, risks for side effects and toxicity remain as PLWH must take life-long medications. Antiretroviral drugs impact autophagy, an intracellular proteolytic process that eliminates debris and foreign material, provides nutrients for metabolism, and performs quality control to maintain cell homeostasis. Toxicity and adverse events associated with antiretrovirals may be due, in part, to their impacts on autophagy. A more complete understanding of the effects on autophagy is essential for developing antiretroviral drugs with decreased off target effects, meaning those unrelated to viral suppression, to minimize toxicity for PLWH. This review summarizes the findings and highlights the gaps in our knowledge of the impacts of antiretroviral drugs on autophagy.
