RESUMO
HIV-1, Hepatitis B and HTLV-1 have similar risk factors and shared routes of transmission and MSM are disproportionately affected by HIV. The aim of the study was to determine the prevalence of HTLV-1 and HBsAg positivity at initial enrolment among MSM attending a large HIV Clinic in Trinidad. Chart reviews were conducted between 2 and 15 January 2024, among self-identified MSM and a comparative group of randomly selected self-identified heterosexual males where sociodemographic, clinical and laboratory data were collected and analysed using SPSS Version 25. During the period April 2002-31 October 2023, in total there were 10,424 patients registered at the clinic, of whom 1255 (12.0%) were self-identified MSM, with an age range of 19-85 years and a median age of 40 years. There were 1822 randomly selected heterosexual males, with an age range of 18-94 years old and a median age of 52 years. Among the MSM, there were 21 (1.67%) patients who were HIV-1/HTLV-1-coinfected, 64 (5.10%) who were HIV-1/HBsAg-coinfected and two (0.16%) who were coinfected with all three viruses (HIV-1/HTLV-1/HBsAg) as compared to 47 ((2.58%) HIV-1/HTLV-1-coinfected (p = 0.12), 69 (3.79%) HIV-1/HBsAg-coinfected (p = 0.10) and three (0.16%) patients coinfected with all three viruses among the heterosexual males. There were no patients with HTLV-1-related diseases among the HIV-1/HTLV-1-coinfected patients and there were no deaths from chronic liver disease in patients coinfected with HIV-1/HBsAg. Despite the availability of an efficacious vaccine, there is a prevalence of hepatitis B of 5.1% among MSM attending the HIV Clinic in Trinidad; therefore, programmes to increase health literacy, screening and immunization are urgently needed.

Mpox is a viral zoonotic disease that is endemic in Central and West Africa and belongs to the Orthopoxvirus genus. A global outbreak of mpox began in May 2022, mainly due to the transmission of the clade 11b virus through person-to-person contact with the lesions or scabs of a person infected with mpox. The data on mpox infection in the Caribbean is sparse. Here we report the clinical features and follow-up of the first two confirmed cases of mpox in Trinidad and Tobago (T&T). Both patients were men who have sex with men (MSM) who presented with genital lesions and expressed concern about increased stigma towards their already marginalized community.
RESUMO
Strategies to improve the scale-up of antiretroviral therapy (ART) for patients with HIV in Trinidad and Tobago, including the adoption of the "Test and Treat All" policy, have accompanied an increase in the number of patients with pretreatment HIV drug resistance (PDR) in the country. However, the scale of this public health problem is not well established. The objective of this study was to estimate the prevalence of PDR and evaluate its impact on viral suppression among patients with HIV receiving care at a large HIV treatment center in Trinidad and Tobago. We retrospectively analyzed data from the Medical Research Foundation of Trinidad and Tobago of patients newly diagnosed with HIV who had HIV genotyping performed. PDR was defined as having at least one drug-resistant mutation. We assessed the impact of PDR on achieving viral suppression within 12 months of ART initiation, using a Cox extended model. Among 99 patients, 31.3% had PDR to any drug, 29.3% to a non-nucleoside reverse transcriptase inhibitor (NNRTI), 3.0% to a nucleoside reverse transcriptase inhibitor, and 3.0% to a protease inhibitor. Overall, 67.1% of the patients who initiated ART (n = 82) and 66.7% (16/24) of patients with PDR achieved viral suppression within 12 months. We found no significant association between PDR status and achieving viral suppression within 12 months [adjusted hazard ratio: 1.08 (95% confidence interval: 0.57-2.04)]. There is a high prevalence of PDR in Trinidad and Tobago, specifically driven by NNRTI resistance. Although we found no difference in virologic suppression by PDR status, there is an urgent need for an effective HIV response to address the many drivers of virologic failure. Accelerating access to affordable, quality-assured generic dolutegravir and adopting it as the preferred first-line ART therapy are critical.

Our aim was to determine the incidence disseminated histoplasmosis and cryptococcal antigenemia among 280 patients with a CD4<350 cells/mm3 attending a large HIV clinic in Trinidad over the period November 2021-June 2022. Sera were screened for cryptococcal antigen (CrAg) using the Immy CrAg Immunoassay (EIA) and the Immy CrAg lateral flow assay (LFA). Urine was screened for Histoplasma antigen using the Immy EIA and the Optimum Imaging Diagnostics (OIDx) LFA. For the purposes of analysis, it was assumed, that all patients with positive urine Histoplasma antigen tests by both EIA and LFA and those with a single positive urine Histoplasma antigen test and clinical features of disseminated histoplasmosis were true positives. The incidence of probable disseminated histoplasmosis and cryptococcal antigenemia were 6.4% (18/280) and 2.5% (7/280) respectively. The sensitivity and specificity of the Immy Histoplasma EIA were 100% (95% CI, 81.5%-100%) and 98.5% (95% CI, 96.1% - 99.6%) respectively as compared to the OIDx Histoplasma LFA of 88.9% (95% CI, 65.3% - 98.6%) and 93.9% (95% CI, 90.3% - 96.5%) respectively, with substantial agreement between the 2 test kits (Kappa value = 0.763; 95% CI 0.685, 0.841). Testing for disseminated histoplasmosis in HIV patients is important in endemic areas.

BACKGROUND: Persons living with HIV may be at risk of more severe forms of COVID-19 infection and minimizing health risks largely depends on their acceptance of the COVID-19 vaccinations. OBJECTIVE: This study examined the correlates and predictors of COVID-19 vaccine hesitancy among persons living with HIV in Trinidad and Tobago. METHODS: A cross-sectional survey using a structured interview was conducted. Data were compiled on patient socio-demographics, diagnosed chronic diseases, psychological factors, and decisions to take the COVID-19 vaccine. Pearson χ2 tests examined the associations between study variables and COVID-19 vaccine hesitancy, and multivariable logistic regression analyses examined its predictors. RESULTS: In this study, 84% were virally suppressed, i.e., HIV viral load <1000 copies/ml. COVID-19 vaccine hesitancy was found to be 39%. Univariate analysis showed that higher vaccine hesitancy was significantly associated with females (OR 2.02, 95% CI 1.23-3.33) and patients of mixed ethnicity (OR 1.84, 95% CI 1.07-3.15). In our multivariable analysis, psychological factors namely, confidence in the COVID-19 vaccine (OR 0.16, 95% CI 0.05-0.47), the perceived benefits of the vaccine (OR 0.54, 95% CI 0.37-0.79), and cues to action (OR 0.68, 95% CI 0.47-0.97) were observed as predictors of COVID-19 vaccine hesitancy. CONCLUSION: Psychological factors such as confidence in the COVID-19 vaccine, perceived benefits of the vaccine, and cues to action were possible predictors of COVID-19 vaccine hesitancy. This study underscored the continued need for strategies to increase confidence and knowledge about the benefits of taking the COVID-19 vaccine among persons living with HIV.
RESUMO
Trichomoniasis is the most common non-viral sexually transmitted infection (STI) occurring worldwide and the majority of infected persons (70-85%) have mild or no genital symptoms. Symptoms in women may include a vaginal discharge which may be associated with vulval irritation and most infections can be effectively treated with metronidazole 500mg bd for seven days. Trichomoniasis unresponsive to 5-nitroimidazole therapy is uncommon but results in substantial therapeutic challenges, especially in resource limited countries. We present such a case which was eventually treated with a low-cost intravaginal combination of boric acid and clotrimazole cream.

Studies have shown that HIV-1/HTLV-1 coinfected patients tend to have higher CD4+ counts than HIV singly infected patients. Two chart reviews were conducted at initial enrolment among patients attending a large HIV Clinic in Trinidad, one to determine the prevalence of HIV-1/HVLV-1 coinfection and another to compare the CD4+ counts and opportunistic infections among HIV-1/HTLV-1 coinfected patients compared to a randomly selected comparison group of HIV-1 singly infected patients. Sociodemographic, clinical and laboratory data were collected and analysed using SPSS Version 25. During the period April 2002−December 2018, 8916 HIV-1 patients were enrolled at the clinic; 159 were HIV-1/HTLV-1 coinfected; the age range was 18−81 years; the median age was 40 years; 87 (54.7%) were females; and the median CD4+ count and median HIV-1 viral load at enrolment were 300 cells/mm3 and 128,543 copies/mL, respectively, with an HTLV-1 seroprevalence of 1.78%. Among the 477 HIV-1 singly infected patients, the age range was 18−71 years; the median age was 33 years; 248 (52.0%) were males; and the median CD4+ count and the median HIV viral load were 295 cells/mm3 and 23,369 copies/mL, respectively. Opportunistic infections (OIs) were diagnosed in 59 (37.1%) of the coinfected patients versus 48 (10.1%) among those HIV singly infected (p < 0.001). HIV-1/HTLV-1 coinfected patients had higher HIV-1 viral loads (p < 0.001) and more OIs, suggesting a worse prognosis though there were no statistically significant differences in CD4+ counts (p = 0.96) as compared to the HIV-1 mono-infected patients.
RESUMO
BACKGROUND: Syphilis among men who have sex with men (MSM) living with HIV is of public health concern, thus the objective of the study is to determine the correlates of prevalent syphilis infection in this population so that urgent interventions could be instituted. METHODS: A cross-sectional study was conducted during the period September 2020-June 2021 among MSM who attended a large HIV Clinic in Trinidad. A questionnaire was administered to obtain socio-demographic data and correlates of prevalent syphilis and patients were screened for syphilis using the traditional algorithm. Descriptive and bivariate analyses were conducted and multivariable logistic regression factors was used to assess factors significantly associated with a syphilis diagnosis. RESULTS: Two hundred and sixty four MSM were enrolled; age range 18-64 years, median age 33 years and 89 (34.4%) were actively bisexual. The prevalence of syphilis was 28% (74/264) and 89.2% (66/74) of these infections were asymptomatic. Multivariable logistic regression analysis showed that those patients who participated in sex with anonymous partners (OR 2.09; 95% CI, 1.03-4.26), those with a previous diagnosis of syphilis (OR 5.16; 95% CI, 1.03-25.83) and those who used marijuana in the last 12 months (OR 2.13; 95% CI, 1.14-3.96) were more likely to be diagnosed with syphilis. CONCLUSION: There is a high prevalence of asymptomatic syphilis among MSM living with HIV in Trinidad. Repeat episodes of syphilis and anonymous sex may play a role in the transmission dynamics of T pallidum infection in this population, thus urgent public health prevention interventions are warranted.

The data on psoriasis in persons infected with HIV in the Caribbean is sparse. A cross-sectional study was conducted on patients attending the HIV Clinic diagnosed with psoriasis where sociodemographic data and data on the pattern of psoriasis were collected and analysed using SPSS version 25. Over the period April 2002-December 2018, 37 persons attending the HIV clinic were diagnosed with psoriasis, age range at psoriasis diagnosis 13-70 years, mean age at diagnosis 37.7 years and 32 (86.5%) were male. Over the study period, 8916 patients were registered at the HIV Clinic and the prevalence of psoriasis among these patients was 0.42% which is less than the reported prevalence of psoriasis among persons infected with HIV of 2-3% in other studies. Severe/generalised psoriasis was present in 7 (18.9%) patients while 30 (81.1%) patients had mild/moderate psoriasis. A family history of psoriasis was present in 1 (2.7%) patient, psoriatic arthritis was present in 2 (5.4%) patients and 31 (83.8%) patients reported that there was improvement in the psoriasis with the topical therapy provided. The study makes an original contribution in the determination of the prevalence and pattern of psoriasis among patients attending a HIV Clinic in Trinidad.

BACKGROUND: Patients who default from HIV care are usually poorly adherent to antiretroviral treatment which results in suboptimal viral suppression. The study assessed the outcomes of retention in care and viral suppression by expansion of an intervention using two patient tracers to track patients lost to follow up at a large HIV clinic in Trinidad. METHODS: Two Social Workers were trained as patient tracers and hired for 15 months (April 2017-June 2018) to call patients who were lost to follow up for 30 days or more during the period July 2016-May 2018 at the HIV clinic Medical Research Foundation of Trinidad and Tobago. RESULTS: Over the 15-month period, of the of 2473 patients who missed their scheduled visits for 1 month or more, 261 (10.6%) patients were no longer in active care-89 patients dead, 65 migrated, 55 hospitalized, 33 transferred to another treatment clinic and 19 incarcerated. Of the remaining 2212 patients eligible for tracing, 1869 (84.5%) patients were returned to care, 1278 (68.6%) were virally unsuppressed (viral load > 200 copies/ml) and 1727 (92.4%) were re-initiated on ART. Twelve months after their return, 1341 (71.7%) of 1869 patients were retained in care and 1154 (86.1%) of these were virally suppressed. Multivariate analysis using logistic regression showed that persons were more likely to be virally suppressed if they were employed (OR, 1.39; 95% CI 1.07-1.80), if they had baseline CD4 counts < 200 cells/mm3 (OR, 1.71; 95% CI 1.26-2.32) and if they were retained in care at 12 months (OR, 2.48; 95% CI 1.90-3.24). Persons initiated on ART for 4-6 years (OR, 3.09; 95% CI 1.13-8.48,), 7-9 years (OR, 3.97; 95% CI 1.39-11.31), > 10 years (OR, 5.99; 95% CI 1.74-20.64 were more likely to be retained in care. CONCLUSIONS: Patient Tracing is a feasible intervention to identify and resolve the status of patients who are loss to follow up and targeted interventions such as differentiated care models may be important to improve retention in care.

A chart review study was conducted to determine the prevalence of syphilis and explore the associated risk factors among men who have sex with men (MSM) who attended a large HIV clinic in Trinidad during the period January-December 2019. Patients were routinely screened for syphilis annually, and demographic, clinical, and laboratory data were extracted from the medical records. Descriptive and bivariate analyses were performed, and factors significantly associated with a syphilis diagnosis were assessed using multivariate logistic regression. During the period, 218 MSM were seen, age range 19-67 years, and median age 34.0 years. The prevalence of syphilis was 41.3% (90/218), and 71.1% (64//90) of these infections were asymptomatic. Multivariate analysis using logistic regression showed that MSM living with HIV in the 30-34 years old-age group (OR, 4.32; 95% CI, 1.04-18.02), and those with a previous history of treated syphilis (OR, 10.18; 95% CI, 4.60-22.53) were more likely to be diagnosed with syphilis. The prevalence of syphilis is high among MSM attending the HIV clinic in Trinidad, and most of these infections were asymptomatic; hence, targeted and sustained interventions to reduce syphilis transmission are urgently required. Repeat episodes of syphilis may play a role in the transmission dynamics of syphilis in MSM.

Objective: : To estimate the incidence and prevalence of serious fungal infections in Trinidad and Tobago (T&T), with a population of 1 394 973 million. Methods: : The medical literature was searched to obtain published data on the incidence and prevalence of fungal infections in the Caribbean. If data were unavailable, estimations were performed using the frequencies of fungal infection in populations at risk. Asthma and pulmonary tuberculosis rates were used to derive the prevalence of allergic bronchopulmonary aspergillosis (ABPA), severe asthma with fungal sensitization (SAFS), and chronic pulmonary aspergillosis (CPA). Results: : The estimated annual burden of fungal infections was 46 156 persons (3.3% of the population), including 21 455 women with recurrent vulvovaginal candidiasis, 118 persons with invasive aspergillosis, 3637 adults with ABPA, 4800 with SAFS, and 178 with CPA. Annually, we estimated 70 cases of candidemia and 14 647 cases of tinea capitis in children. Of the 11 000 persons living with HIV/AIDS, it was estimated that there were 40 cases of cryptococcal meningitis, 88 cases of disseminated histoplasmosis, and 124 cases of Pneumocystis pneumonia. Conclusion: : There seems to be an extensive burden of fungal infections in T&T. Hence, targeted interventions are required to improve clinical and laboratory diagnosis and a national surveillance system should be implemented.
RESUMO
The HIV Clinic at the Medical Reserch Foundation of Trinidad and Tobago (MRFTT) in collaboration with the Ministry of Health (MoH) supports national level diagnostic efforts by conducting HIV viral load testing using the Abbott m2000 real time poymerase chain reation (PCR) platform installed at the MRFTT Laboratory. The MRFTT is strategically poised to scale up diagnostic PCR testing for SARS-CoV-2. In August 2020, the SARS-CoV-2 pandemic in Trinidad and Tobago was categorized as having community spread. To support the government's efforts to rapidly scale up testing and reduce the turn around time whie delivering quality results, an agreement was reached with MoH to expand diagnostic testing for SARS-CoV-2 at the MRFTT laboratory. Goals: 1. Support the efforts of government to rapidly scale up testing for SARS-CoV-2 2. Integrate SARS-CoV-2 testing at a Regional HIV Care and Treatment Site.

In Trinidad and Tobago, despite persons living with HIV (PLHIV) having access to subsidised treatment and care, only 47% PLHIV attain viral suppression. The study assessed the role of individual-level factors on viral suppression among PLHIV in Trinidad and Tobago. Data from 9,629 PLHIV who attended an HIV clinic between 2016 and 2018 were analysed. Cases were aged ≥18 who met the CDC HIV case definition. Viral suppression defined as a viral load of <200 copies/ml at last assessment. The chi-square test of association determined statistically significant relationships between individual factors and viral suppression. Logistic regression was used to estimate odds ratios (OR) for viral suppression. PLHIV who were males (OR = 0.76, 95% CI 0.67-0.87), men who have sex with men (MSM) (OR = 0.82, 95% CI 0.67-0.99), single/unmarried (OR = 0.69, 95% CI 0.55-0.87), aged 18-24 years (OR = 0.66, 95% CI 0.49-0.89), aged 25-49 years (OR = 0.81, 95% CI 0.70-0.94) were less likely to achieve viral suppression. These study findings demonstrate that retention/adherence programmes must urgently identify and target vulnerable PLHIV populations in Trinidad and Tobago to improve viral suppression. Further research examining community and societal factors, such as stigma and discrimination, is warranted.
