Abstract
Idiosyncratic drug reactions (IDRs) are associated with significant patient morbidity/mortality and lead to considerable drug candidate attrition in drug development. Their idiosyncratic nature makes the study of IDRs difficult. In particular, nevirapine is associated with a relatively high risk of serious skin rash and liver injury. We previously found that nevirapine causes a similar skin rash in female Brown Norway rats, but these animals do not develop significant liver injury. Programmed cell death protein-1 (PD-1) is an immune checkpoint involved in immune tolerance, and anti-PD-1 antibodies have been used to treat cancer. However, they increase the risk of liver injury caused by co-administered drugs. We found that PD-1-/- mice are more susceptible to drug-induced liver injury, but PD-1-/- mice are not a good model for all drugs. In particular, they do not develop a skin rash when treated with nevirapine, at least in part because they lack the sulfotransferase in their skin that forms the reactive metabolite responsible for the rash. Therefore, we developed a PD-1 mutant (PD-1m/m) rat, with an excision in the ligand-binding domain of PD-1, to test whether nevirapine would cause a more serious skin rash in these animals. The PD-1m/m rat was based on a Sprague Dawley background, which has a lower incidence of skin rash than Brown Norway rats. The treated PD-1m/m rats developed more severe liver injury than PD-1-/- mice, but in contrast to expectations, they did not develop a skin rash. Functional knockouts provide a unique tool to study the mechanisms of IDRs.

Skin infiltrating T-cell profile of drug reaction with eosinophilia and systemic symptoms (DRESS) reactions among HIV-infected patients. Front Med (Lausanne) 2023; 10:1118527. [PMID: 37215719 PMCID: PMC10196146 DOI: 10.3389/fmed.2023.1118527] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Accepted: 04/17/2023] [Indexed: 05/24/2023] Open
Abstract
Introduction Drug Reaction with Eosinophilia Systemic Symptoms (DRESS) is more common in persons living with HIV (PLHIV), and first-line anti-TB drugs (FLTDs) and cotrimoxazole are the commonest offending drugs. Limited data is available on the skin infiltrating T-cell profile among DRESS patients with systemic CD4 T-cell depletion associated with HIV. Materials and methods HIV cases with validated DRESS phenotypes (possible, probable, or definite) and confirmed reactions to either one or multiple FLTDs and/or cotrimoxazole were chosen (n = 14). These cases were matched against controls of HIV-negative patients who developed DRESS (n = 5). Immunohistochemistry assays were carried out with the following antibodies: CD3, CD4, CD8, CD45RO and FoxP3. Positive cells were normalized to the number of CD3+ cells present. Results Skin infiltrating T-cells were mainly found in the dermis. Dermal and epidermal CD4+ T-cells (and CD4+/CD8+ ratios) were lower in HIV-positive vs. negative DRESS; p < 0.001 and p = 0.004, respectively; without correlation to whole blood CD4 cell counts. In contrast, no difference in dermal CD4+FoxP3+ T-cells was found in HIV-positive vs. negative DRESS, median (IQR) CD4+FoxP3+ T-cells: [10 (0-30) cells/mm2 vs. 4 (3-8) cells/mm2, p = 0.325]. HIV-positive DRESS patients reacting to more than one drug had no difference in CD8+ T-cell infiltrates, but higher epidermal and dermal CD4+FoxP3+ T-cell infiltrates compared to single drug reactors. Conclusion DRESS, irrespective of HIV status, was associated with an increased skin infiltration of CD8+ T-cells, while CD4+ T-cells were lower in HIV-positive DRESS compared to HIV-negative DRESS skin. While inter-individual variation was high, the frequency of dermal CD4+FoxP3+ T-cells was higher in HIV-positive DRESS cases reacting to more than one drug. Further research is warranted to understand the clinical impact of these changes.

Abstract
Skin diseases are hallmarks of progressive HIV-related immunosuppression, with severe noninfectious inflammatory and hypersensitivity conditions as common as opportunistic infections. Conditions such as papular pruritic eruption are AIDS defining, whereas delayed immune-mediated adverse reactions, mostly cutaneous, occur up to 100-fold more during HIV infection. The skin, constantly in contact with the external environment, has a complex immunity. A dense, tightly junctioned barrier with basal keratinocytes and epidermal Langerhans cells with antimicrobial, innate-activating, and antigen-presenting functions form the frontline. Resident dermal dendritic, mast, macrophage, and innate lymphoid cells play pivotal roles in directing and polarizing appropriate adaptive immune responses and directing effector immune cell trafficking. Sustained viral replication leads to progressive declines in CD4 T cells, whereas Langerhans and dermal dendritic cells serve as viral reservoirs and points of first viral contact in the mucosa. Cutaneous cytokine responses and diminished lymphoid populations create a crucible for exaggerated inflammation and hypersensitivity. However, beyond histopathological description, these manifestations are poorly characterized. This review details normal skin immunology, changes associated with progressive HIV-related immunosuppression, and the characteristic conditions of immune dysregulation increased with HIV. We highlight the main research gaps and several novel tissue-directed strategies to define mechanisms that will provide targeted approaches to prevention or treatment.

Abstract
Abstract
Background
Globally, the human immunodeficiency virus has been recognized as a major public health concern. The direct toxicity of antiretroviral medicines or their active metabolites causes liver cell destruction by different mechanisms, inducing immune-mediated inflammation, oxidative stress, and other mechanisms. On the other hand, the virus itself also produces hepatotoxicity. Therefore, this systematic review and meta-analysis aimed to assess the pooled prevalence of hepatotoxicity among HIV-infected patients in Ethiopia.
Methods
PubMed, Science Direct, Cochrane Library, Web of Science, and ResearchGate databases were used to find relevant articles. As well, various professional associations were searched to retrieve grey literature. The Newcastle–Ottawa Quality Assessment Scale was used to assess the quality of recruited studies. The data were extracted using Microsoft Excel, and the meta-analysis was carried out using STATA 14 software. I2 and Cochran’s Q test were employed to assess the presence of heterogeneity between studies. A random effect model was used. The funnel plot and Egger’s statistics were used to assess publication bias. Moreover, subgroup analysis and sensitivity analysis were also done.
Results
The pooled prevalence of hepatotoxicity among HIV patients in Ethiopia was 25.45% (95% CI = 20.06–30.84%). There was high heterogeneity, with an I2 value of 93.7%. Subgroup analysis by HAART status showed a higher pooled prevalence of hepatotoxicity among HIV patients taking HAART (23.63%) than among HAART naive patients (7.29%). In subgroup analysis, the pooled prevalence of hepatotoxicity among HIV/Tb co-infected and HIV mono-infected patients was 26.3% and 17.94%, respectively.
Conclusion
The current systematic review and meta-analysis showed a high prevalence of hepatotoxicity among HIV-infected patients. Therefore, regular monitoring of hepatotoxicity among HIV-infected patients is required in order to avoid liver damage and other complications.

Abstract
Introduction Hepatotoxicity is one of the risk factors associated with treatment non-adherence, which is the main risk factor for drug resistance. Therefore, this study aimed to determine the incidence and risk factors of hepatotoxicity during highly active antiretroviral therapy (HAART) among people living with HIV in Ethiopia. Methods A prospective cohort study was conducted between April 2007 and January 2011 at Saint Peter Specialized Hospital, Akaki and Kality Health Centers, Addis Ababa, Ethiopia. A total of 316 HIV-infected adult individuals (70 participants were HIV and TB co-infected and 246 were infected with HIV alone) were included in this study. The study participants were followed for a total of 18 months with or without HAART. Socio-demographic data were collected using a structured questionnaire, and venous blood samples were collected for laboratory tests. Logistic regression and Poisson regression were used to determine the independent effect of each variable on hepatotoxicity at baseline and end of follow-up. Results Of 316 HIV-infected people, 72 (22.8%) participants had an elevated ALT/AST which was 100% mild-to moderate hepatotoxicity at baseline. Baseline CD4 T-cell count (p = 0.027) and HIV co-infection with TB (p < 0.001) were independently associated with hepatotoxicity at baseline. The overall incidence rate of hepatotoxicity in participants on HAART (21.8 per 100 person-years) was lower than participants who were HAART naïve (33.3 per 100 person-years) (p = 0.009). Conclusion High incidence of mild-to-moderate hepatotoxicity and low severe hepatotoxicity were observed in HIV-infected individuals who were on HAART or were HAART naïve. HAART may minimize the occurrence of hepatotoxicity. Although HAART could minimize hepatotoxicity among HIV-infected people, to manage mild and moderate hepatotoxicity liver function test monitoring is required.

Abstract
Nevirapine (NVP) is a first-generation non-nucleoside reverse transcriptase inhibitor widely used for the treatment and prophylaxis of human immunodeficiency virus infection. The drug is taken throughout the patient's life and, due to the availability of an extended-release formulation, it is administered once daily. This antiretroviral is one of the scarce examples of drugs with prescription criteria based on sex, in order to prevent adverse reactions. The therapy with NVP has been associated with potentially life-threatening liver and idiosyncratic skin toxicity. Multiple evidence has emerged regarding the formation of electrophilic NVP metabolites as crucial for adverse idiosyncratic reactions. The formation of reactive metabolites that yield covalent adducts with proteins has been demonstrated in patients under NVP-based treatment. Interestingly, several pharmacogenetic- and sex-related factors associated with NVP toxicity can be mechanistically explained by an imbalance toward increased formation of NVP-derived reactive metabolites and/or impaired detoxification capability. Moreover, the haptenation of self-proteins by these reactive species provides a plausible link between NVP bioactivation and immunotoxicity, further supporting the relevance of this toxicokinetics hypothesis. In the current paper, we review the existing knowledge and recent developments on NVP metabolism and their relation to NVP toxicity.

Abstract
OBJECTIVES Two nucleos(t)ide reverse-transcriptase inhibitors (NRTIs) plus 1 non-NRTI (nNRTI) remain the preferred or alternative combination antiretroviral therapy (cART) for antiretroviral-naive HIV-positive patients in Taiwan. The three most commonly used nNRTIs are nevirapine (NVP), efavirenz (EFV) and rilpivirine (RPV). This study aimed to determine the incidences of hepatotoxicity and skin rashes within 4 weeks of initiation of cART containing 1 nNRTI plus 2 NRTIs. METHODS Between June, 2012 and November, 2015, all antiretroviral-naive HIV-positive adult patients initiating nNRTI-containing cART at 8 designated hospitals for HIV care were included in this retrospective observational study. According to the national HIV treatment guidelines, patients were assessed at baseline, 2 and 4 weeks of cART initiation, and subsequently every 8 to 12 weeks. Plasma HIV RNA load, CD4 cell count and aminotransferases were determined. The toxicity grading scale of the Division of AIDS (DAIDS) 2014 was used for reporting clinical and laboratory adverse events. RESULTS During the 3.5-year study period, 2,341 patients initiated nNRTI-containing cART: NVP in 629 patients, EFV 1,363 patients, and RPV 349 patients. Rash of any grade occurred in 14.1% (n = 331) of the patients. In multiple logistic regression analysis, baseline CD4 cell counts (per 100-cell/μl increase, adjusted odds ratio [AOR], 1.125; 95% confidence interval [95% CI], 1.031-1.228) and use of NVP (AOR, 2.443; 95% CI, 1.816-3.286) (compared with efavirenz) were independently associated with the development of skin rashes. Among the 1,455 patients (62.2%) with aminotransferase data both at baseline and week 4, 72 (4.9%) developed grade 2 or greater hepatotoxicity. In multiple logistic regression analysis, presence of antibody for hepatitis C virus (HCV) (AOR, 2.865; 95% CI, 1.439-5.704) or hepatitis B surface antigen (AOR, 2.397; 95% CI, 1.150-4.997), and development of skin rashes (AOR, 2.811; 95% CI, 1.051-7.521) were independently associated with the development of hepatotoxicity. CONCLUSIONS The baseline CD4 cell counts and use of NVP were associated with increased risk of skin rashes, while hepatotoxicity was independently associated with HCV or hepatitis B virus coinfection, and development of skin rashes in antiretroviral-naïve HIV-positive Taiwanese patients within 4 weeks of initiation of nNRTI-containing regimens.

Abstract
BACKGROUND Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare but life-threatening adverse drug reaction. Several criteria have been established to aid the diagnosis. However, patients with DRESS remained underdiagnosis and undertreatment. METHODS Medical records of hospitalized patients at the King Chulalongkorn Memorial Hospital from January 2004-December 2014 due to DRESS were enrolled retrospectively using RegiSCAR diagnostic criteria. RESULTS A total of 52 patients were included. Thirty-seven patients (71.2%) were female. The four most common causative agents were phenytoin (23.1%), nevirapine (17.3%), allopurinol (15.4%), and cotrimoxazole (13.5%). The overall prevalence was 9.63 cases per 100,000 inpatients. Median onset time (IQR) was 16 (9-27) days. Allopurinol was associated with longer onset time than others (p = 0.014). CLINICAL PRESENTATION skin rash 100%, fever 78.8%, and lymphadenopathy 50%. The majority (84.6%) had single internal organ involvement. The most common internal organ involvement was liver (94.2%). Allopurinol was associated with higher incidence of renal involvement (p = 0.01). Up to 60% of patients had eosinophilia. Allopurinol was associated with higher eosinophilia (p = 0.003). A half of patients received systemic corticosteroids. Two mortality cases were reported (omeprazole-fulminant hepatitis and phenytoin-nosocomial infection). CONCLUSIONS DRESS is associated with severe morbidity and mortality. Phenytoin, nevirapine, allopurinol, and cotrimoxazole were the major causes. Allopurinol-induced DRESS had the longest onset time, and was associated with higher eosinophilia and incidence of renal involvement. Raising awareness among both health care providers and public for early detection and withdrawal of the causative agent is critical to save life and reduce morbidity.

Presence of Tablet Remnants of Nevirapine Extended-Release in Stools and Its Impact on Virological Outcome in HIV-1-Infected Patients: A Prospective Cohort Study. PLoS One 2015; 10:e0140574. [PMID: 26465325 PMCID: PMC4605833 DOI: 10.1371/journal.pone.0140574] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2015] [Accepted: 09/26/2015] [Indexed: 01/24/2023] Open
Abstract
Background Nevirapine extended-release (NVP-XR) taken once daily remains an effective antiretroviral agent for patients infected with HIV-1 strains that do not harbor resistance mutations. Presence of tablet remnants of NVP XR in stools was reported in 1.19% and 3.05% of subjects in two clinical trials. However, the prevalence may have been underestimated because the information was retrospectively collected in the studies. Methods Between April and December 2014, we prospectively inquired about the frequency of noticing tablet remnants of NVP XR in stools in HIV-1-infected patients who switched to antiretroviral regimens containing NVP XR plus 2 nucleos(t)ide reverse-transcriptase inhibitors. Patients were invited to participate in therapeutic drug monitoring of plasma concentrations of NVP 12 or 24 hours after taking the previous dose (C12 and C24, respectively) of NVP XR using high-performance liquid chromatography. The information on clinical characteristics, including plasma HIV RNA load and CD4 lymphocyte count, at baseline and during follow-up was recorded. Results During the 9-month study period, 272 patients switched to NVP XR-based regimens and 60 (22.1%) noticed tablet remnants of NVP XR in stools, in whom 54.2% reported noticing the tablet remnants at least once weekly. Compared with patients who did not notice tablet remnants, those who noticed tablet remnants had a higher mean CD4 lymphocyte count (629 vs 495 cells/mm3, P = 0.0002) and a similar mean plasma HIV RNA load (1.57 vs 1.61 log10 copies/mL, P = 0.76) on switch. At about 12 and 24 weeks after switch, patients who noticed tablet remnants continued to have a similar mean plasma HIV RNA load (1.39 vs 1.43 log10 copies/mL, P = 0.43; and 1.30 vs 1.37 log10 copies/mL, P = 0.26, respectively), but had a lower median NVP C12 (3640 vs 4730 ng/mL, P = 0.06), and a similar median NVP C24 (3220 vs 3330 ng/ml, P = 0.95) when compared with those who did not notice tablet remnants. Conclusions The presence of tablet remnants of NVP XR in stools is not uncommon in HIV-1-infected Taiwanese patients receiving NVP XR-based antiretroviral regimens, which does not have an adverse impact on the virological and immunological outcomes.

Population-representative incidence of drug-induced acute liver failure based on an analysis of an integrated health care system. Gastroenterology 2015; 148:1353-61.e3. [PMID: 25733099 PMCID: PMC4446162 DOI: 10.1053/j.gastro.2015.02.050] [Citation(s) in RCA: 75] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2014] [Revised: 02/24/2015] [Accepted: 02/24/2015] [Indexed: 12/11/2022]
Abstract
BACKGROUND & AIMS Medications are a major cause of acute liver failure (ALF) in the United States, but no population-based studies have evaluated the incidence of ALF from drug-induced liver injury. We aimed to determine the incidence and outcomes of drug-induced ALF in an integrated health care system that approximates a population-based cohort. METHODS We performed a retrospective cohort study using data from the Kaiser Permanente Northern California (KPNC) health care system between January 1, 2004, and December 31, 2010. We included all KPNC members age 18 years and older with 6 months or more of membership and hospitalization for potential ALF. The primary outcome was drug-induced ALF (defined as coagulopathy and hepatic encephalopathy without underlying chronic liver disease), determined by hepatologists who reviewed medical records of all KPNC members with inpatient diagnostic and laboratory criteria suggesting potential ALF. RESULTS Among 5,484,224 KPNC members between 2004 and 2010, 669 had inpatient diagnostic and laboratory criteria indicating potential ALF. After medical record review, 62 (9.3%) were categorized as having definite or possible ALF, and 32 (51.6%) had a drug-induced etiology (27 definite, 5 possible). Acetaminophen was implicated in 18 events (56.3%), dietary/herbal supplements in 6 events (18.8%), antimicrobials in 2 events (6.3%), and miscellaneous medications in 6 events (18.8%). One patient with acetaminophen-induced ALF died (5.6%; 0.06 events/1,000,000 person-years) compared with 3 patients with non-acetaminophen-induced ALF (21.4%; 0.18/1,000,000 person-years). Overall, 6 patients (18.8%) underwent liver transplantation, and 22 patients (68.8%) were discharged without transplantation. The incidence rates of any definite drug-induced ALF and acetaminophen-induced ALF were 1.61 events/1,000,000 person-years (95% confidence interval, 1.06-2.35) and 1.02 events/1,000,000 person-years (95% confidence interval, 0.59-1.63), respectively. CONCLUSIONS Drug-induced ALF is uncommon, but over-the-counter products and dietary/herbal supplements are its most common causes.
