Treating HIV-associated cytomegalovirus retinitis with oral valganciclovir and intra-ocular ganciclovir by primary HIV clinicians in southern Myanmar: a retrospective analysis of routinely collected data.

BACKGROUND: Cytomegalovirus retinitis (CMVR) is an opportunistic infection in HIV-infected people. Intraocular or intravenous ganciclovir was gold standard for treatment; however, oral valganciclovir replaced this in high-income countries. Low- and middle-income countries (LMIC) frequently use intraocular injection of ganciclovir (IOG) alone because of cost. METHODS: Retrospective review of all HIV-positive patients with CMVR from February 2013 to April 2017 at a Médecins Sans Frontièrs HIV clinic in Myanmar. Treatment was classified as local (IOG) or systemic (valganciclovir, or valganciclovir and IOG). The primary outcome was change in visual acuity (VA) post-treatment. Mortality was a secondary outcome. RESULTS: Fifty-three patients were included. Baseline VA was available for 103 (97%) patient eyes. Active CMVR was present in 72 (68%) eyes. Post-treatment, seven (13%) patients had improvement in VA, 30 (57%) had no change, and three (6%) deteriorated. Among patients receiving systemic therapy, four (12.5%) died, compared with five (24%) receiving local therapy (p = 0.19). CONCLUSIONS: Our results from the first introduction of valganciclovir for CMVR in LMIC show encouraging effectiveness and safety in patients with advanced HIV. We urge HIV programmes to include valganciclovir as an essential medicine, and to include CMVR screening and treatment in the package of advanced HIV care.

High levels of viral repression, malnutrition and second-line ART use in adolescents living with HIV: a mixed methods study from Myanmar.

BACKGROUND: Adolescents living with HIV/AIDS (ALHIV) are a particularly vulnerable but often overlooked group in the HIV response despite additional disease management challenges. METHODS: All ALHIV (10-19 years), on ART for ≥6 months, presenting to care at a Médecins Sans Frontières (MSF) clinic in Myanmar from January-April 2016 were eligible for the quantitative study component (clinical history, medical examination, laboratory investigation). A subset of these respondents were invited to participate in qualitative interviews. Interviews and focus groups were also conducted with other key informants (care givers, clinicians). RESULTS: Of 177 ALHIV, 56% (100) were aged 9-13 years and 77 (44%) were 14-19. 49% (86) had been orphaned by one parent, and 19% (33) by both. 59% (104) were severely underweight (BMI < 16). 47% presented with advanced HIV (WHO stage III/IV). 93% were virally supressed (< 250 copies/mL). 38 (21%) of ALHIV were on a second-line ART after first-line virological failure. Qualitative interviewing highlighted factors limiting adherence and the central role that HIV counsellors play for both ALHIV patients and caregivers. CONCLUSIONS: Our study shows good clinical, immunological, and virological outcomes for a cohort of Myanmar adolescents living with HIV, despite a majority being severely underweight, presenting with Stage III or IV illness, and the prevalence of comorbid infections (TB). Many treatment and adherence challenges were articulated in qualitative interviewing but emphasized the importance of actively engaging adolescents in their treatment. Comprehensive HIV care for this population must include routine viral load testing and social support programs.

Epidemiological characteristics and real-world treatment outcomes of hepatitis C among HIV/HCV co-infected patients in Myanmar: A prospective cohort study.

Background and Aims: In Myanmar, public sector treatment programs for hepatitis C virus (HCV) infection were nonexistent until June 2017. WHO highlights the importance of simplification of HCV service delivery through task-shifting among health workers and decentralization to the primary health care level. Between November 2016 and November 2017, a study was conducted to describe the epidemiological data and real-world outcomes of treating HIV/HCV coinfected patients with generic direct acting antiviral (DAA) based regimens in the three HIV clinics run by nonspecialist medical doctors in Myanmar. Methods: HCV co-infection among people living with HIV (PLHIV) from two clinics in Yangon city and one clinic in Dawei city was screened by rapid diagnostic tests and confirmed by testing for viral RNA. Nonspecialist medical doctors prescribed sofosbuvir and daclatasvir based regimens (with or without ribavirin) for 12 or 24 weeks based on the HCV genotype and liver fibrosis status. Sustained virologic response at 12 weeks after treatment (SVR12) was assessed to determine cure. Results: About 6.5% (1417/21,777) of PLHIV were co-infected with HCV. Of 864 patients enrolled in the study, 50.8% reported history of substance use, 27% history of invasive medical procedures and 25.6% history of incarceration. Data on treatment outcomes were collected from 267 patients of which 257 (96.3%) achieved SVR12, 7 (2.6%) failed treatment, 2 (0.7%) died and 1 (0.4%) became loss to follow-up. Conclusion: The study results support the integration of hepatitis C diagnosis and treatment with DAA-based regimens into existing HIV clinics run by nonspecialist medical doctors in a resource-limited setting. Epidemiological data on HIV/HCV co-infection call for comprehensive HCV care services among key populations like drug users and prisoners in Yangon and Dawei.

Routine Immediate Eye Examination at the Point of Care for Diagnosis of AIDS-Related Cytomegalovirus Retinitis Among Patients With a CD4 Count <100 in Myanmar.

A retrospective review of diagnosis of cytomegalovirus retinitis (CMVR) before and after introduction of routine immediate eye examination among AIDS patients in Myanmar with an absolute CD4 T-cell count <100 cells/µL demonstrated an increased detection of CMVR from 1.1% (14/1233) to 10.7% (65/608), an improvement of ~10-fold. Diagnosis of CMVR was achieved a mean of 2 days after clinic enrollment.

Sugar, dental caries and the incidence of acute rheumatic fever: a cohort study of Maori and Pacific children.

OBJECTIVE: To determine whether dental caries, as an indicator of cumulative exposure to sugar, is associated with the incidence of acute rheumatic fever and chronic rheumatic heart disease, in Maori and Pacific children aged 5 and 6 years at their first dental visit. MATERIALS AND METHODS: A cohort study was undertaken which linked school dental service records of caries with national hospital discharge and mortality records. Cox models were used to investigate the strength of the association between dental caries and rheumatic fever incidence. RESULTS: A total of 20 333 children who were free of rheumatic heart disease at enrolment were available for analysis. During a mean follow-up time of 5 years, 96 children developed acute rheumatic fever or chronic rheumatic heart disease. After adjustment for potential confounders, children with five or more primary teeth affected by caries were 57% (95% CI: 20% to 106%) more likely to develop disease during follow-up, compared to children whose primary teeth were caries free. The population attributable to the risk for caries in this cohort was 22%. CONCLUSIONS: Dental caries is positively associated with the incidence of acute rheumatic fever and chronic rheumatic heart disease in Maori and Pacific children. Sugar intake, an important risk factor for dental caries, is also likely to influence the aetiology of rheumatic fever.
