Abstract
Chronic pain is a prevalent neurological complication among individuals living with human immunodeficiency virus (PLHIV) in the post-combination antiretroviral therapy (cART) era. These individuals experience malfunction in various cellular and molecular pathways involved in pain transmission and modulation, including the neuropathology of the peripheral sensory neurons and neurodegeneration and neuroinflammation in the spinal dorsal horn. However, the underlying etiologies and mechanisms leading to pain pathogenesis are complex and not fully understood. In this review, we aim to summarize recent progress in this field. Specifically, we will begin by examining neuropathology in the pain pathways identified in PLHIV and discussing potential causes, including those directly related to HIV-1 infection and comorbidities, such as antiretroviral drug use. We will also explore findings from animal models that may provide insights into the molecular and cellular processes contributing to neuropathology and chronic pain associated with HIV infection. Emerging evidence suggests that viral proteins and/or antiretroviral drugs trigger a complex pathological cascade involving neurons, glia, and potentially non-neural cells, and that interactions between these cells play a critical role in the pathogenesis of HIV-associated pain.

Open Forum Infect Dis 2023; 10:ofad350.

Abstract
Chronic pain is common among people with human immunodeficiency virus (HIV) and detrimental to quality of life and overall health. It is often underdiagnosed, undertreated, and frankly dismissed in women with HIV, despite growing evidence that it is highly prevalent in this population. Thus, we conducted a systematic review and meta-analysis to estimate the global prevalence of chronic pain in women with HIV. The full protocol can be found on PROSPERO (identifier CRD42022301145). Of the 2984 references identified in our search, 36 were included in the systematic review and 35 in the meta-analysis. The prevalence of chronic pain was 31.2% (95% confidence interval [CI], 24.6%-38.7%; I2 = 98% [95% CI, 97%-99%]; P < .0001). In this global assessment, we found a high prevalence of chronic pain among women with HIV, underscoring the importance of understanding the etiology of chronic pain, identifying effective treatments, and conducting regular assessments in clinical practice.

Expression in skin biopsies supports genetic evidence linking CAMKK2, P2X7R and P2X4R with HIV-associated sensory neuropathy. J Neurovirol 2023; 29:241-251. [PMID: 37166584 PMCID: PMC10404215 DOI: 10.1007/s13365-023-01134-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 04/05/2023] [Accepted: 04/07/2023] [Indexed: 05/12/2023]
Abstract
HIV-associated sensory neuropathy (HIV-SN) affects 14-38% of HIV+ individuals stable on therapy with no neurotoxic drugs. Polymorphisms in CAMKK2, P2X7R and P2X4R associated with altered risk of HIV-SN in Indonesian and South African patients. The role of CaMKK2 in neuronal repair makes this an attractive candidate, but a direct role for any protein is predicated on expression in affected tissues. Here, we describe expression of CaMKK2, P2X7R and P2X4R proteins in skin biopsies from the lower legs of HIV+ Indonesians with and without HIV-SN, and healthy controls (HC). HIV-SN was diagnosed using the Brief Peripheral Neuropathy Screen. Biopsies were stained to detect protein gene product 9.5 on nerve fibres and CaMKK2, P2X7R or P2X4R, and were examined using 3-colour sequential scanning confocal microscopy. Intraepidermal nerve fibre densities (IENFD) were lower in HIV+ donors than HC and correlated directly with nadir CD4 T-cell counts (r = 0.69, p = 0.004). However, IENFD counts were similar in HIV-SN+ and HIV-SN- donors (p = 0.19) and so did not define neuropathy. CaMKK2+ cells were located close to dermal and epidermal nerve fibres and were rare in HC and HIV-SN- donors, consistent with a role for the protein in nerve damage and/or repair. P2X7R was expressed by cells in blood vessels of HIV-SN- donors, but rarely in HC or HIV-SN+ donors. P2X4R expression by cells in the epidermal basal layer appeared greatest in HIV-SN+ donors. Overall, the differential expression of CaMKK2, P2X7R and P2X4R supports the genetic evidence of a role for these proteins in HIV-SN.

Abstract
Evidence indicates that over half of all people with HIV (PWH) will experience nonmalignant chronic pain throughout their lifetimes, with increasing prevalence as they age. Peripheral neuropathy resulting from the neurotoxic effects of HIV itself and the medications used to treat HIV were widely considered the primary cause of acute and chronic pain early on in the antiretroviral treatment era. However, recent studies suggest a predominance of non-neuropathic (e.g., musculoskeletal) pain in PWH with uncertain etiology. Chronic pain is often widespread in PWH, affecting multiple body locations. Additional research is needed to better understand contributors to chronic pain in PWH, which is likely to include biological (e.g., immune dysregulation), psychological (e.g., substance abuse) and social (e.g., stigma) factors.

TNF-Block Genotypes Influence Susceptibility to HIV-Associated Sensory Neuropathy in Indonesians and South Africans. Int J Mol Sci 2020; 21:ijms21020380. [PMID: 31936167 PMCID: PMC7014294 DOI: 10.3390/ijms21020380] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 12/11/2019] [Accepted: 12/26/2019] [Indexed: 11/17/2022] Open
Abstract
HIV-associated sensory neuropathy (HIV-SN) is a disabling complication of HIV disease and antiretroviral therapies (ART). Since stavudine was removed from recommended treatment schedules, the prevalence of HIV-SN has declined and associated risk factors have changed. With stavudine, rs1799964*C (TNF-1031) associated with HIV-SN in Caucasians and Indonesians but not in South Africans. Here, we investigate associations between HIV-SN and rs1799964*C and 12 other polymorphisms spanning TNF and seven neighboring genes (the TNF-block) in Indonesians (n = 202; 34/168 cases) and South Africans (n = 75; 29/75 cases) treated without stavudine. Haplotypes were derived using fastPHASE and haplotype networks built with PopART. There were no associations with rs1799964*C in either population. However, rs9281523*C in intron 10 of BAT1 (alternatively DDX39B) independently associated with HIV-SN in Indonesians after correcting for lower CD4 T-cell counts and >500 copies of HIV RNA/mL (model p = 0.0011, Pseudo R2 = 0.09). rs4947324*T (between NFKBIL1 and LTA) independently associated with reduced risk of HIV-SN and shared haplotype 1 (containing no minor alleles) associated with increased risk of HIV-SN after correcting for greater body weight, a history of tuberculosis and nadir CD4 T-cell counts (model: p = 0.0003, Pseudo R2 = 0.22). These results confirm TNF-block genotypes influence susceptibility of HIV-SN. However, critical genotypes differ between ethnicities and with stavudine use.

Abstract
BACKGROUND Increasing age of HIV-1 infected population brought about the risk of frailty as comorbidity, whose prevalence is higher in low and middle-income countries (LMICs). Indonesia as an LMIC also bears a major burden of HIV-1 epidemic with a similarly aging population, but the prevalence of frailty and its predictors are unknown. OBJECTIVES To identify the prevalence of frailty and analyze its associated factors, among HIV-1 infected adults under antiretroviral therapy in Indonesia. METHODS A cross-sectional study was conducted among HIV-infected individuals with inclusion criteria of age ≥30 years old and underwent ART for at least 6 months. The main assessment was done using Fried's frailty phenotype score, which categorizes subjects into non-frail, pre-frail, or frail. Factors associated with frailty were characterized and multiple logistic regression analysis was performed. RESULTS A total of 164 subjects were recruited; male subjects were 118 (72%), the median age was 40.5 years old, and the median CD4 nadir was 53 cells/μl. Frailty was identified among 90 (54.9%) subjects with 84 (51.2%) identified as pre-frail and 6 (3.7%) as frail, with dominant frailty phenotype was weakness in grip strength. The multivariate model showed that depression was the only factor significantly correlated with pre-frailty and frailty (OR 2.14; 95% CI 1.04-4.43, p=0.036). CONCLUSION Frailty is a common occurrence among HIV-infected patients under ART, with depression as an independent predictive factor.
