This study estimates platelet count changes over time in HIV/HCV co-infected participants and compares them with the changes in platelet count among HIV mono-infected participants to test if HIV/HCV co-infection is associated with lower platelet counts. Methods: This retrospective cohort study included all HIV treatment naive patients from four sites in the Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) cohort with platelet count measurements between 2002 and 2009. We conducted a mixed effects linear regression modeling the mean change in platelet count per year while adjusting for age, sex, race, baseline CD4 cell count, and site. Index date was the first platelet count after 2002, and participants were censored upon initiation of treatment for HIV or HCV. Results: There were 929 HIV/HCV co-infected and 3558 HIV mono-infected participants with a mean follow-up time of 1.2 years. HIV/HCV co-infected participants had on average a slighter lower platelet count at baseline (234,040 vs. 242,780/μL;p-value = 0.004), and a more rapid mean reduction per year (7230 vs. 3580/μL;p-value 0.001) after adjusting for age, sex, baseline CD4 count. Conclusions: In treatment naive participants, HIV/HCV co-infection is associated with a more rapid decline in platelet count compared with HIV mono-infection.展开更多

To assess the interaction between HIV and HCV disease progression, we examined 82 HIV/HCV co-infection patients and 62 HCV infection patients. METHODS: Liver function, pathological changes, infec- tion duration, immune function and qualitative HCV-RNA and HCV antibody were compared retrospectively between the two groups of patients. RESULTS: Fourty-eight patients (58.5%) in the HIV/ HCV co-infection group and 53 patients (85.5%) in the HCV infection group showed abnormal liver function. No significant difference was observed in inflammation and fi- brosis in the two groups P =0.187, 0.954). However, liver abnormality in the patients with HIV/HCV co-infection appeared 8 years earlier than in those with HCV infection alone (P<0.001). As to immune function, the counts of CD4+T and CD8+ T in the HIV/HCV group were (226.35 ± 173.49)×106/L and (914. 40 ±448. 28)×106/L, whereas in the HCV group they were (752.31±251.69)×l06/L and (529.011170.67)×106/L respectively. The difference in the two groups was highly significant (P<0.001; P<0.001). The ratio of the number of people with both HCV-RNA and HCV antibody positive to the number of HCV-RNA positive and HCV antibody negative in the HIV/HCV group was 52:9, whereas in the HCV group it was 44:1 (P = 0.043). CONCLUSION: HIV/HCV co-infection can accelerate de- terioration of hepatitis C, which may be due to the effect of HIV on cellular immunity and humoral immunity of the body.展开更多

It has been described that HCV co-infection leads to neuropsychological impairment whose severity is greater than in mono-HIV infected subjects. In the present study we assessed the neuropsychological status of 46 human immunodeficiency virus (HIV)-infected individuals from the Warsaw Hospital for Infectious Diseases. For the purpose of cognitive assessment, neuropsychological tests measuring global cognitive functions, attention and perception, verbal memory, as well as non-verbal aspects of executive functions, e.g. visual monitoring and planning, were assessed. In 60% of the investigated patients, who were co-infected with the hepatitis C virus, the overall cognitive outcome observed was worse than in mono-HIV infected subjects. The following factors were taken into account: ART therapy’s influence on cognitive functions using the CPE rank (CNS Penetration Efficacy, 2010), route of HIV transmission, conditions of human existence and age of investigated patients. The present work should be treated as a preliminary research and interpreted in the context of several limitations described in the text.展开更多

In this group of patients, the primary cause of mortality is liver disease, which accounts for up to 14% of deaths. HIV/HCV co-infection also exposes patients to a higher risk of progression to AIDS, a faster evolution towards cirrhosis, more frequent drug toxicity, and lower tolerance for antiretroviral therapy. Moreover, HCV infection can play a part in increasing immune system depression;neurological, cognitive and renal damage;and bone fragility. Hence an optimal antiretroviral regimen needs to be chosen for co-administration with anti-HCV therapy and timed appropriately to improve the prognosis of co-infected HIV/HCV patients. Unfortunately, however, data on the safety and efficacy of antiretroviral drugs in these patients is scarce, as are studies of pharmacokinetics in patients with advanced liver impairment. Furthermore, restoring adequate immune constitution seems not to slow the progression of liver disease, and the metabolic and hepatic toxicity of some antiretroviral drugs can even contribute to inflammatory and fibrogenic processes. It is therefore essential that HIV/HCV co-infected patients receive only medications capable of ensuring the best immune recovery but possessing the lowest potential to trigger immune reconstitution syndrome or hepatic and metabolic damage.展开更多

The aim of this study was to assess the frequency of HIV-HBV co-infection among people who living with HIV (PLHIV) in the infectious and tropical diseases department of the Centre Hospitalier Universitaire de lAmiti Sino-Centrafricaine in Bangui. Methods: A retrospective study was carried out from January 1, 2010 to December 31, 2021 in the Infectious and Tropical Diseases Department at the Amiti Sino-Centrafricaine University Hospital. It included the files of all PLHIV, which included the results of HBV serology. A standardized form was used to collect socio-demographic and professional data by documentary review. Data was analysed using Epi-Info 7 software. Means, proportions were calculated as well as Chi square witch was significant if p-value was below 0.05. Results: The study included 265 patients, 188 were women (70.1%) and 77 men (29.1%), giving a sex ratio of 0.45. Mean age was 35.8 years, higher in men (40 years) than in women (35.8 years) (p 0.0001). The age groups 25 to 34 (37.7%) and 35 to 44 (33.6%) were in the majority (71.3%). The majority of PLHIV were unemployed (57.1%), including housewives (43.0%). HBV prevalence was 14.3%, including 7.2% among the unemployed, who account for half of all co-infections. The search for associations between HIV-HBV co-infection and all socio-demographic characteristics (age, sex, marital status) and socio-professional categories showed no significant difference (p 0.05). Conclusion: PLHIV were predominantly young adults, female, and unemployed;no occupation was significantly associated with co-infection. The vast majority of co-infected people were not covered by the occupational health system (unemployed or informal sector). Urgent action is needed to improve workers access to occupational medicine in CAR.展开更多

This study aimed to determine the prevalence of HBV and HCV in people living with HIV and to evaluate the performance of a combined rapid test for the simultaneous detection of HIV, HBV, and HCV. Methods: This is a cross-sectional study that took place from February 2017 to November 2018 and included 139 HIV-infected individuals followed up at different medical centers in Ouagadougou, Burkina Faso. HBV and HCV serology tests were performed on-site using finger prick whole blood with HIV/HCV/HBsAg combined rapid test and then serum with two reference tests “Architect HBsAg Qualitative” and “Architect HIV Ag/Ab Combo”. Results: The mean age of the participants was 57 ± 8 years. Of the 139 participants, 10% (14/139) were HIV-1 positive, 71.9% (100/139) were HIV-2 positive, and 18.0% (25/139) were HIV-1/HIV-2 coinfected. The sensitivity and specificity of the HIV/HCV/HBsAg combined rapid test were 33.33% vs 99.11% and 20% vs 99.25% compared to Architect HBsAg Qualitative and Architect HIV Ag/Ab Combo, respectively. The Kappa and Youden Index values were 0.4262 and 0.3244 and 0.2707 and 0.1925, respectively, compared to each of the two reference tests. Conclusion: The results show that the HIV/HCV/HBsAg combined rapid test has poor diagnostic efficiency and should not be recommended for the diagnosis of these viruses.展开更多

Hepatitis C virus (HCV) is a major causative agent of chronic liver disease and infects an estimated 170 million people worldwide,resulting in a serious public health burden. Due to shared routes of transmission,co-infection with HIV and HCV has become common among individuals who had high risks of blood exposures. Among hemophiliacs the co-infection rate accounts for 85%; while among injection drug users (IDU) the rate can be as high as 90%. HIV can accelerate the progression of HCV-related liver disease,particularly when immunodeficiency has developed. Although the effect of HCV on HIV infection is controversial,most studies showed an increase in mortality due to liver disease. HCV may act as a direct cofactor to fasten the progression of AIDS and decrease the tolerance of highly active antiretroviral therapy (HARRT). Conversely,HAART-related hepatotoxicity may enhance the progression of liver fibrosis. Due to above complications,co-infection with HCV and HIV-1 has imposed a critical challenge in the management of these patients. In this review,we focus on the epidemiology and transmission of HIV and HCV,the impact of the two viruses on each other,and their treatment.展开更多

Of the world’s population, 3% are estimated to have chronic Hepatitis C Virus (HCV) infection, which is responsible for about 70% of cases of chronic hepatitis (accelerated chronicity in the presence of HIV and for such major complications as cirrhosis and hepatocellular carcinoma. The fibrosis 4 (FIB-4) and Aspartate aminotransferase/platelet ratio index (APRI) scores are simple, inexpensive tests accessible to most people, and their performance has not yet been studied in C?te d’Ivoire. Objective: To prospectively evaluate the diagnostic performance of APRI and FIB-4 scores in liver damage in those co-infected with HIV/HCV in C?te d’Ivoire. Methods: This study was conducted over three months. The patients came from national blood transfusion center of the cities of Man and Daloa. The criteria for selecting respondents were at least 18 years of age and a positive test for HIV and HCV. APRI and FIB-4 scores were calculated for each patient from biological data obtained by COBAS C311 (Roche Hitachi, Japan). Statistical analyses were performed using GraphPad and MED-CALC software. Results: Our study involved 30 patients (men) of middle age (25 - 52 years), with extremes ranging from 0.67 to 8 for APRI and 0.201 to 22 for FIB-4. A predictive APRI and FIB4 score of significant hepatic fibrosis was observed in 23% of patients;however, 46% and 54% of patients for the APRI and FIB-4 score, respectively, would not have significant fibrosis. An APRI and FIB4 score not included in the classification limits of the type of fibrosis hepatitis was observed in 31% and 23% of patients, respectively. Conclusion: The performance of the APRI and FIB-4 biological scores analyzed according to the interpretation of their cut-off values would enable classifying about 70% and 77%, respectively, of the patient population in the stages of hepatitis C fibrosis.展开更多

Researchers have studied the burden of co-infection of HIV with hepatitis B and hepatitis C but the risk factors and clinical presentation have not been much addressed especially in children. Methodology: This was a prospective cross sectional study that determined the prevalence, risk factors, clinical features, baseline CD4<sup>+</sup> count, CD4<sup>+</sup> percentage, and alanine aminotransferase (ALT) of newly diagnosed, HAART na?ve HIV co-infection among children who were managed at a Tertiary Hospital in Ilorin, Nigeria. Result: Of the 60 HIV- infected children recruited, 11.7% had HIV co-infection with HBV or HCV. Children with co-infec- tions (mean age 8.43 ± 2.37 years) were significantly older than their HIV mono-infected counterparts (mean age 5.25 ± 3.96 years) (p = 0.011). There was no significant difference between HIV monoinfection and HIV co-infection with respect to gender (p = 0.758), ethnicity (p = 0.707), religion of parents (p = 0.436), family type (p = 0.184), social class (p = 0.535), previous transfusion (p = 0.053), scarification (p = 0.612), female genital mutilation (p = 0.778), and sharing of clippers (p = 0.806). The mean BMI, immunological staging (p = 0.535), baseline ALT (p = 0.940), and mean baseline CD4<sup>+</sup> count (p = 0.928) were comparable. However, the body mass index of HIV co-infec- ted children decreased with age up till age 10 years. Conclusion: There were no risk factors, nor clinical features predictive of co-infection identified in this study. Co-infection did not negatively impact baseline, CD4<sup>+</sup> count and ALT.展开更多

Conclusions:In developing countries with a high prevalence of tuberculosis in the general population,the possibility of incidental tuberculosis in patients with HIV should always be considered.CD4 count does not appear to influence the severity of tuberculosis.The presence of concomitant evidence of immunosuppression in the form of category B and C conditions is indicative of underlying immunosuppression and associated with a significantly lower CD4 count.展开更多

Malaria diagnosis was performed based on microscopic examination of patients' blood smears. Chemiluminescent microparticle immunoassay and gel particle passive agglutination were employed for the detection of HIV antigen in patients' plasma. Results: Plasmodium falciparum(P. falciparum) and Plasmodium vivax(P. vivax) are the two predominant malaria species with the ratio of about 1: 1 to 1.5:1. Most of the P. falciparum cases were presented with acute uncomplicated signs and symptoms with highest parasitemia of 1 045 000 asexual parasites/μL bloods. The prevalence of malaria and HIV co-infection during 2005-2007 was 1.35%(2/148 cases, 1 each for P. falciparum and P. vivax co-infection), but was increased to 2.78%(3/108 cases, 2 and 1 for P. falciparum and P. vivax co-infection, respectively) during 2010-2012.Conclusions: The increasing trend of prevalence of malaria and HIV co-infection in Mae Sot, Tak province was of a great concern on either pharmacodynamics or pharmacokinetics aspect. The study in a larger numbers of malaria patients in different endemic areas throughout the country with different time periods is underway.展开更多

Tuberculosis is the leading cause of death among people living with HIV. Africa accounts for the majority of co-infection episodes, with over 50% of cases in some parts of southern Africa. In the Democratic Republic of Congo (DRC), around 9% of persons living with HIV (PLHIV) develop TB and 11% of TB patients are infected with HIV. The DRC is one of the 30 countries in the world bearing the brunt of co-infection. Despite the efforts made by countries to improve access to antiretroviral traitement (ART), TB remains a major problem among people living with HIV. The Lingwala Health Zone in the provincial city of Kinshasa recorded a large number of cases of HIV/TB co-infection during the study period. The aim of this study was to determine the factors associated with HIV/TB co-infection among PLHIV on ART in the Lingwala health zone (HZ) in Kinshasa. Methods: This was a case-control study conducted in the state-run HIV care facilities in the Lingwala health district among PLHIV who had visited the health facilities during the period 2021-2023. Cases were coinfected patients and controls were PLHIV who had not developed tuberculosis during the study period. Results: A total of 281 PLHIV were enrolled in the study, with 70 cases and 211 controls. Factors associated with HIV/TB co-infection after multivariate analysis were viral load (OR = 5.34;95% CI;1.8-15.8, p = 0.005). History of tuberculosis (OR = 20.84;95% CI;8.6-50.3, p -85.0, p = 0.005) and BMI Conclusion: The results of this study indicate that the detection of these enumerated factors should prompt providers to actively search for tuberculosis with a view to organising early management.展开更多
文摘Background: Previous research has suggested an association between infection with hepatitis C virus (HCV) or with human immunodeficiency virus (HIV) and low platelet counts. This study estimates platelet count changes over time in HIV/HCV co-infected participants and compares them with the changes in platelet count among HIV mono-infected participants to test if HIV/HCV co-infection is associated with lower platelet counts. Methods: This retrospective cohort study included all HIV treatment naive patients from four sites in the Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) cohort with platelet count measurements between 2002 and 2009. We conducted a mixed effects linear regression modeling the mean change in platelet count per year while adjusting for age, sex, race, baseline CD4 cell count, and site. Index date was the first platelet count after 2002, and participants were censored upon initiation of treatment for HIV or HCV. Results: There were 929 HIV/HCV co-infected and 3558 HIV mono-infected participants with a mean follow-up time of 1.2 years. HIV/HCV co-infected participants had on average a slighter lower platelet count at baseline (234,040 vs. 242,780/μL;p-value = 0.004), and a more rapid mean reduction per year (7230 vs. 3580/μL;p-value 0.001) after adjusting for age, sex, baseline CD4 count. Conclusions: In treatment naive participants, HIV/HCV co-infection is associated with a more rapid decline in platelet count compared with HIV mono-infection.

文摘BACKGROUND:Co-infection of hepatitis C virus (HCV) and human immunodeficiency virus type 1 ( HIV-1 ) is common in hemophiliacs and drug abusers. To assess the interaction between HIV and HCV disease progression, we examined 82 HIV/HCV co-infection patients and 62 HCV infection patients. METHODS: Liver function, pathological changes, infec- tion duration, immune function and qualitative HCV-RNA and HCV antibody were compared retrospectively between the two groups of patients. RESULTS: Fourty-eight patients (58.5%) in the HIV/ HCV co-infection group and 53 patients (85.5%) in the HCV infection group showed abnormal liver function. No significant difference was observed in inflammation and fi- brosis in the two groups P =0.187, 0.954). However, liver abnormality in the patients with HIV/HCV co-infection appeared 8 years earlier than in those with HCV infection alone (P<0.001). As to immune function, the counts of CD4+T and CD8+ T in the HIV/HCV group were (226.35 ± 173.49)×106/L and (914. 40 ±448. 28)×106/L, whereas in the HCV group they were (752.31±251.69)×l06/L and (529.011170.67)×106/L respectively. The difference in the two groups was highly significant (P<0.001; P<0.001). The ratio of the number of people with both HCV-RNA and HCV antibody positive to the number of HCV-RNA positive and HCV antibody negative in the HIV/HCV group was 52:9, whereas in the HCV group it was 44:1 (P = 0.043). CONCLUSION: HIV/HCV co-infection can accelerate de- terioration of hepatitis C, which may be due to the effect of HIV on cellular immunity and humoral immunity of the body.

文摘Human immunodeficiency virus (HIV) is the infectious agent causing acquired immu-nodeficiency syndrome (AIDS),a deadliest scourge of human society. Hepatitis C virus (HCV) is a major causative agent of chronic liver disease and infects an estimated 170 million people worldwide,resulting in a serious public health burden. Due to shared routes of transmission,co-infection with HIV and HCV has become common among individuals who had high risks of blood exposures.

Due to above complications,co-infection with HCV and HIV-1 has imposed a critical challenge in the management of these patients. In this review,we focus on the epidemiology and transmission of HIV and HCV,the impact of the two viruses on each other,and their treatment.
文摘Hepatitis C infection in people living with Human Immunodeficiency Virus (HIV) poses management challenges. Of the world’s population, 3% are estimated to have chronic Hepatitis C Virus (HCV) infection, which is responsible for about 70% of cases of chronic hepatitis (accelerated chronicity in the presence of HIV and for such major complications as cirrhosis and hepatocellular carcinoma. The fibrosis 4 (FIB-4) and Aspartate aminotransferase/platelet ratio index (APRI) scores are simple, inexpensive tests accessible to most people, and their performance has not yet been studied in C?te d’Ivoire. Objective: To prospectively evaluate the diagnostic performance of APRI and FIB-4 scores in liver damage in those co-infected with HIV/HCV in C?te d’Ivoire. Methods: This study was conducted over three months. The patients came from national blood transfusion center of the cities of Man and Daloa. The criteria for selecting respondents were at least 18 years of age and a positive test for HIV and HCV. APRI and FIB-4 scores were calculated for each patient from biological data obtained by COBAS C311 (Roche Hitachi, Japan). Statistical analyses were performed using GraphPad and MED-CALC software. Results: Our study involved 30 patients (men) of middle age (25 - 52 years), with extremes ranging from 0.67 to 8 for APRI and 0.201 to 22 for FIB-4. A predictive APRI and FIB4 score of significant hepatic fibrosis was observed in 23% of patients;however, 46% and 54% of patients for the APRI and FIB-4 score, respectively, would not have significant fibrosis. An APRI and FIB4 score not included in the classification limits of the type of fibrosis hepatitis was observed in 31% and 23% of patients, respectively. Conclusion: The performance of the APRI and FIB-4 biological scores analyzed according to the interpretation of their cut-off values would enable classifying about 70% and 77%, respectively, of the patient population in the stages of hepatitis C fibrosis.
文摘Background: Human immunodeficiency virus and hepatitis B and C viruses are endemic in sub- Saharan African countries including Nigeria. Researchers have studied the burden of co-infection of HIV with hepatitis B and hepatitis C but the risk factors and clinical presentation have not been much addressed especially in children. Methodology: This was a prospective cross sectional study that determined the prevalence, risk factors, clinical features, baseline CD4<sup>+</sup> count, CD4<sup>+</sup> percentage, and alanine aminotransferase (ALT) of newly diagnosed, HAART na?ve HIV co-infection among children who were managed at a Tertiary Hospital in Ilorin, Nigeria. Result: Of the 60 HIV- infected children recruited, 11.7% had HIV co-infection with HBV or HCV. Children with co-infec- tions (mean age 8.43 ± 2.37 years) were significantly older than their HIV mono-infected counterparts (mean age 5.25 ± 3.96 years) (p = 0.011). There was no significant difference between HIV monoinfection and HIV co-infection with respect to gender (p = 0.758), ethnicity (p = 0.707), religion of parents (p = 0.436), family type (p = 0.184), social class (p = 0.535), previous transfusion (p = 0.053), scarification (p = 0.612), female genital mutilation (p = 0.778), and sharing of clippers (p = 0.806). The mean BMI, immunological staging (p = 0.535), baseline ALT (p = 0.940), and mean baseline CD4<sup>+</sup> count (p = 0.928) were comparable. However, the body mass index of HIV co-infec- ted children decreased with age up till age 10 years. Conclusion: There were no risk factors, nor clinical features predictive of co-infection identified in this study. Co-infection did not negatively impact baseline, CD4<sup>+</sup> count and ALT.
文摘Direct-acting antiviral(DAA)therapies are efficacious for the achievement of sustained virologic response(SVR)in almost all treated hepatitis C virus(HCV)-infected patients.However,the impacts of HCV eradication on immune function and chronic immune activation in the long-term remain controversial and limited,especially in patients co-infected with human immunodeficiency virus(HIV).Indeed,although restoration of many immune responses clearly can be observed,several features of immune perturbations persist over time after HCV clearance.Understanding the degree and reasons of the partial recovery of the immune system in chronic HCV/HIV coinfection after HCV elimination is pivotal to avoid disease progression and possible long-term clinical outcomes in cured patients,as well as contributing to the development of immunotherapy drug design.
文摘Objective:To determine the relationship between tuberculosis and the degree of immunosuppression as determined by CD4 count.The impact of immunosuppression on the severity of tuberculosis was also studied.Methods:A retrospective analysis was performed in patients newly diagnosed with HIV infection and antiretroviral therapy(ART)-naive patients with known HIV seropositivity.All patients were diagnosed with active tuberculosis between January 2008 and December 2010,based on review of their medical records.Patients on chemoprophylaxis for opportunistic infection were excluded.Pattern and severity of tuberculosis,associated stigmata of immunosuppression,and CD4 counts were noted.Results:Of 140 patients satisfying the inclusion criteria.52 had mild tuberculosis with no other evidence of immunosuppression,52 had tuberculosis of variable severity with associated evidence of immunosuppression,and 36 had severe tuberculosis with no other evidence of immunosuppression.The CD4 count was highest in the first group[【109.2±99.9) cells/μL]and least in the second group[(58.4±39.8) cells/μL], and the difference was statistically significant(P=0.004).No statistical difference was observed in the CD4 count between those with mild tuberculosis and those with severe tuberculosis. Conclusions:In developing countries with a high prevalence of tuberculosis in the general population,the possibility of incidental tuberculosis in patients with HIV should always be considered.CD4 count does not appear to influence the severity of tuberculosis.The presence of concomitant evidence of immunosuppression in the form of category B and C conditions is indicative of underlying immunosuppression and associated with a significantly lower CD4 count.

文摘Objective: To preliminarily investigate the prevalence of HIV co-infection in patients with malaria in Mae Sot District, Tak Province of Thailand.Methods: The study was a retrospective study on blood samples collected from a total of 256 patients with malaria(all species and severity) who attended Mae Tao clinic for migrant workers, Tak Province during 2005-2007(148 samples) and 2010-2012(108 samples). Malaria diagnosis was performed based on microscopic examination of patients' blood smears. Chemiluminescent microparticle immunoassay and gel particle passive agglutination were employed for the detection of HIV antigen in patients' plasma. Results: Plasmodium falciparum(P. falciparum) and Plasmodium vivax(P. vivax) are the two predominant malaria species with the ratio of about 1: 1 to 1.5:1. Most of the P. falciparum cases were presented with acute uncomplicated signs and symptoms with highest parasitemia of 1 045 000 asexual parasites/μL bloods. The prevalence of malaria and HIV co-infection during 2005-2007 was 1.35%(2/148 cases, 1 each for P. falciparum and P. vivax co-infection), but was increased to 2.78%(3/108 cases, 2 and 1 for P. falciparum and P. vivax co-infection, respectively) during 2010-2012.Conclusions: The increasing trend of prevalence of malaria and HIV co-infection in Mae Sot, Tak province was of a great concern on either pharmacodynamics or pharmacokinetics aspect. The study in a larger numbers of malaria patients in different endemic areas throughout the country with different time periods is underway.
文摘Context and objective: Around 8% of incident cases of tuberculosis (TB) were reported among people living with HIV worldwide in 2022. Tuberculosis is the leading cause of death among people living with HIV. Africa accounts for the majority of co-infection episodes, with over 50% of cases in some parts of southern Africa. In the Democratic Republic of Congo (DRC), around 9% of persons living with HIV (PLHIV) develop TB and 11% of TB patients are infected with HIV. The DRC is one of the 30 countries in the world bearing the brunt of co-infection. Despite the efforts made by countries to improve access to antiretroviral traitement (ART), TB remains a major problem among people living with HIV. The Lingwala Health Zone in the provincial city of Kinshasa recorded a large number of cases of HIV/TB co-infection during the study period. The aim of this study was to determine the factors associated with HIV/TB co-infection among PLHIV on ART in the Lingwala health zone (HZ) in Kinshasa. Methods: This was a case-control study conducted in the state-run HIV care facilities in the Lingwala health district among PLHIV who had visited the health facilities during the period 2021-2023. Cases were coinfected patients and controls were PLHIV who had not developed tuberculosis during the study period. Results: A total of 281 PLHIV were enrolled in the study, with 70 cases and 211 controls. Factors associated with HIV/TB co-infection after multivariate analysis were viral load (OR = 5.34;95% CI;1.8-15.8, p = 0.005). History of tuberculosis (OR = 20.84;95% CI;8.6-50.3, p -85.0, p = 0.005) and BMI Conclusion: The results of this study indicate that the detection of these enumerated factors should prompt providers to actively search for tuberculosis with a view to organising early management.
