Horváth IL, Bunduc S, Hankó B, Kleiner D, Demcsák A, Szabó B, Hegyi P, Csupor D. No evidence for the benefit of PPIs in the treatment of acute pancreatitis: a systematic review and meta-analysis. Sci Rep 2023; 13:2791. [PMID: 36797320 PMCID: PMC9935541 DOI: 10.1038/s41598-023-29939-5] [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: 10/31/2022] [Accepted: 02/13/2023] [Indexed: 02/18/2023] Open
Abstract
Although current guidelines do not recommend the use of proton pump inhibitors (PPIs) in the standard of care of acute pancreatitis (AP), they are often prescribed in clinical practice, mainly for ulcer stress prophylaxis. In this systematic review and meta-analysis we evaluated the association between the use of PPIs in the management of AP and various clinical outcomes. We conducted the systematic research in six databases without restrictions on January 24th, 2022. We investigated adult patient with AP, who were treated with PPI compared to conventional therapy. The pooled odds ratios, mean differences, and corresponding 95% confidence intervals were calculated with random effect model. We included six RCTs and three cohort studies, consisting of 28,834 patients. We found a significant decrease in the rate of pancreatic pseudocyst formation in patients who received PPI treatment. PPI use was associated with a higher risk of GI bleeding, however this finding could be due to the patients' comorbid conditions. We found no significant difference in the rates of 7-day mortality, length of hospital stay, and acute respiratory distress syndrome between the groups. The available data on this topic are limited; therefore, further well designed RCTs are needed to evaluate the potential benefits and adverse effects of PPIs in AP.

Pharmacokinetics of Pantoprazole and Pantoprazole Sulfone in Goats After Intravenous Administration: A Preliminary Report. Front Vet Sci 2021; 8:744813. [PMID: 34631865 PMCID: PMC8492921 DOI: 10.3389/fvets.2021.744813] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 08/26/2021] [Indexed: 12/29/2022] Open
Abstract
Background: Ruminant species are at risk of developing abomasal ulceration, but there is a lack of pharmacokinetic data for anti-ulcer therapies, such as the proton pump inhibitor pantoprazole, in goats. Objective: The primary study objective was to estimate the plasma pharmacokinetic parameters for pantoprazole in adult goats after intravenous administration. A secondary objective was to describe the pharmacokinetic parameters for the metabolite, pantoprazole sulfone, in goats. Methods: Pantoprazole was administered intravenously to six adult goats at a dose of 1 mg/kg. Plasma samples were collected over 36h and analyzed via reverse phase high performance liquid chromatography for determination of pantoprazole and pantoprazole sulfone concentrations. Pharmacokinetic parameters were determined by non-compartmental analysis. Results: Plasma clearance, elimination half-life, and volume of distribution of pantoprazole were estimated at 0.345 mL/kg/min, 0.7 h, and 0.9 L/kg, respectively following IV administration. The maximum concentration, elimination half-life and area under the curve of pantoprazole sulfone were estimated at 0.1 μg/mL, 0.8 h, and 0.2 hr*μg/mL, respectively. The global extraction ratio was estimated 0.00795 ± 0.00138. All animals had normal physical examinations after conclusion of the study. Conclusion: The reported plasma clearance for pantoprazole is lower than reported for foals, calves, and alpacas. The elimination half-life appears to be < that reported for foals and calves. Future pharmacodynamic studies are necessary for determination of the efficacy of pantoprazole on acid suppression in goats.

The expansion of a patient tracer programme to identify and return patients loss to follow up at a large HIV clinic in Trinidad. AIDS Res Ther 2021; 18:20. [PMID: 33892747 PMCID: PMC8063284 DOI: 10.1186/s12981-021-00341-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Accepted: 04/08/2021] [Indexed: 11/10/2022] Open
Abstract
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.

Abstract
BACKGROUND Dynamic movement of patients in and out of HIV care is prevalent, but there is limited information on patterns of patient re-engagement or predictors of return to guide HIV programs to better support patient engagement. METHODS From a probability-based sample of lost to follow-up, adult patients traced by peer educators from 31 Zambian health facilities, we prospectively followed disengaged HIV patients for return clinic visits. We estimated the cumulative incidence of return and the time to return using Kaplan-Meier methods. We used univariate and multivariable Cox proportional hazards regression to conduct a risk factor analysis identifying predictors of incident return across a social ecological framework. RESULTS Of the 556 disengaged patients, 73.0% [95% confidence interval (CI): 61.0 to 83.8] returned to HIV care. The median follow-up time from disengagement was 32.3 months (interquartile range: 23.6-38.9). The rate of return decreased with time postdisengagement. Independent predictors of incident return included a previous gap in care [adjusted Hazard Ratio (aHR): 1.95, 95% CI: 1.23 to 3.09] and confronting a stigmatizer once in the past year (aHR: 2.14, 95% CI: 1.25 to 3.65). Compared with a rural facility, patients were less likely to return if they sought care from an urban facility (aHR: 0.68, 95% CI: 0.48 to 0.96) or hospital (aHR: 0.52, 95% CI: 0.33 to 0.82). CONCLUSIONS Interventions are needed to hasten re-engagement in HIV care. Early and differential interventions by time since disengagement may improve intervention effectiveness. Patients in urban and tertiary care settings may need additional support. Improving patient resilience, outreach after a care gap, and community stigma reduction may facilitate return. Future re-engagement research should include causal evaluation of identified factors.

Temporary disengagement and re-engagement in human immunodeficiency virus care in a rural county serving pastoralist communities in Kenya: a retrospective cohort study. Int Health 2020; 12:95-100. [PMID: 31227824 PMCID: PMC7057135 DOI: 10.1093/inthealth/ihz049] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2019] [Revised: 05/14/2019] [Accepted: 05/22/2019] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Pastoralist communities are known to be hard to reach. The magnitude of temporary disengagement from human immunodeficiency virus (HIV) care is understudied. METHODS We conducted a retrospective cohort study of temporary disengagement (2 weeks late for a next appointment), virologic response, lost to follow-up (6 months late) and re-engagement in care among patients who started antiretroviral therapy between 2014 and 2016 in Baringo County, Kenya. Predictors of re-engagement after disengagement were estimated using logistic regression. RESULTS Of 342 patients, 76.9% disengaged at least once (range 0-7). Of 218 patients with a viral load (VL), 78.0% had a suppressed VL. Those with a history of temporary disengagement from care were less likely to suppress their VL (p=0.002). Six patients had treatment failure (two consecutive VLs >1000 copies/mm3) and all had disengaged at least once. After disengagement from care, male patients (adjusted odds ratio [aOR] 0.3 [95% confidence interval {CI} 0.2 to 0.6]; p<0.001) and patients with World Health Organization stage III-IV (aOR 0.3 [95% CI 0.1 to 0.5; p<0.001) were less likely to re-engage in care. CONCLUSIONS Temporary disengagement was frequent in this pastoralist setting. This indicator is often overlooked, as most studies only report binary outcomes, such as retention in care. Innovative strategies are required to achieve HIV control in rural settings like this pastoralist setting.

Abstract
Clinical safety data for the use of gastroprotectants in hospitalized ruminants is lacking. In human patients, multiple adverse effects are possible from the use of pantoprazole including hematologic and electrolyte abnormalities as well as anaphylaxis and edema. The medical records of all hospitalized cattle, goats, and sheep administered pantoprazole over an ~5-year period were retrospectively analyzed for adverse effects. Seventy-nine eligible patients were observed. Hypomagnesemia was observed after pantoprazole administration in 10 cattle; however, no significant changes were noted when compared to baseline before pantoprazole administration. Significant changes were noted in serum indicators of hepatic and renal function; however, these represented downward trends that were most likely clinically insignificant. Anaphylaxis after pantoprazole administration was not observed; however, seven cattle displayed edema after pantoprazole administration. Veterinary clinicians should be aware of the potential for hypomagnesemia in hospitalized ruminants being administered pantoprazole and monitor patients accordingly. While these preliminary retrospective results indicate that pantoprazole may be a safe adjunctive therapy in hospitalized ruminants, additional studies are necessary to further determine the safety and toxicity of pantoprazole in ruminants.

Abstract
Background Low retention on combination antiretroviral therapy (cART) has emerged as a threat to the Joint United Nations Programme on human immunodeficiency virus (HIV)/AIDS (UNAIDS) 90-90-90 targets. We examined outcomes of patients who started cART but were subsequently lost to follow-up (LTFU) in African treatment programs. Methods This was a systematic review and individual patient data meta-analysis of studies that traced patients who were LTFU. Outcomes were analyzed using cumulative incidence functions and proportional hazards models for the competing risks of (i) death, (ii) alive but stopped cART, (iii) silent transfer to other clinics, and (iv) retention on cART. Results Nine studies contributed data on 7377 patients who started cART and were subsequently LTFU in sub-Saharan Africa. The median CD4 count at the start of cART was 129 cells/μL. At 4 years after the last clinic visit, 21.8% (95% confidence interval [CI], 20.8%-22.7%) were known to have died, 22.6% (95% CI, 21.6%-23.6%) were alive but had stopped cART, 14.8% (95% CI, 14.0%-15.6%) had transferred to another clinic, 9.2% (95% CI, 8.5%-9.8%) were retained on cART, and 31.6% (95% CI, 30.6%-32.7%) could not been found. Mortality was associated with male sex, more advanced disease, and shorter cART duration; stopping cART with less advanced disease andlonger cART duration; and silent transfer with female sex and less advanced disease. Conclusions Mortality in patients LTFU must be considered for unbiased assessments of program outcomes and UNAIDS targets in sub-Saharan Africa. Immediate start of cART and early tracing of patients LTFU should be priorities.

Abstract
We conducted a qualitative study using focus groups and in-depth interviews to explore barriers to and facilitators of linkage-to-care and antiretroviral treatment (ART) initiation in Botswana. Participants were selected from communities receiving interventions through the Ya Tsie Study. Fifteen healthcare providers and 49 HIV-positive individuals participated. HIV-positive participants identified barriers including stigma, discrimination and overcrowded clinics, and negative staff attitudes; personal factors, such as a lack of acceptance of one's HIV status, non-disclosure, and gender differences; along with lack of social/family support, and certain religious beliefs. Healthcare providers cited delayed test results, poverty, and transport difficulties as additional barriers. Major facilitators were support from healthcare providers, including home visits, social support, and knowing the benefits of ART. Participants were highly supportive of universal ART as a personal health measure. Our results highlighted a persistent structural health facility barrier: HIV-positive patients expressed strong discontent with HIV care/treatment being delivered differently than routine healthcare, feeling inconvenienced and stigmatized by separately designated locations and days of service. This barrier was particularly problematic for highly mobile persons. Addressing this structural barrier, which persists even in the context of high ART uptake, could bring gains in willingness to initiate ART and improved adherence in Botswana and elsewhere.

Guillon M. Success factors for universal access to antiretroviral treatments in South Africa. Int J Health Plann Manage 2018; 33:e1160-e1178. [PMID: 30109898 DOI: 10.1002/hpm.2602] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2017] [Accepted: 07/04/2018] [Indexed: 01/16/2023] Open
Abstract
This article studies the epidemiological and economic impacts of a universal testing and treatment policy of Human Immunodeficiency Virus (HIV) in South Africa. A model of disease transmission is built to simulate several implementation scenarios of the policy. Different behavioral responses in the general population are considered. The results show that the success of a large-scale HIV testing and treatment program in South Africa depends on its implementation conditions. The policy can lead to a reduction of the HIV epidemic, even in the case of a large relapse in preventive behaviors in the general population, if implementation conditions are favorable. This is the case if the number of infected individuals who are infectious is greatly reduced. From an economic point of view, taking into account the positive externality of antiretroviral (ARV) treatments changes the traditional framework of cost-benefit analyses. A large-scale testing and treatment program would be cost-saving in the case of favorable implementation conditions, even following a large increase in risk behaviors after the scaling up of ARV treatments. By contrast, the analysis stresses out the potential perverse effects of scaling up ARV treatments in South Africa if the intervention is set up without ensuring enough resources for patients' monitoring and the availability of effective ARV drugs. Indeed, if the number of treated patients rises while adherence of patients to treatments decreases and the rate of loss to follow-up increases, the policy could extend the pool of infectious patients and lead to a long-term amplification of the epidemic.

Abstract
The present study reports a case of pantoprazole-induced acute kidney disease. The patient was diagnosed with acute kidney injury with wide interstitial inflammation and eosinophil infiltration. Following 1 month of glucocorticoid therapy, the patient's serum creatinine and urea nitrogen decreased to within normal ranges. The presentation, clinical course, diagnosis and prognosis of pantoprazole-induced acute kidney injury are discussed herein to highlight the importance of early and correct diagnosis for good prognosis. Disease characteristics include short-term increased serum creatinine levels that respond to glucocorticoid treatment. The patient had no history of chronic kidney disease or proteinuria and presented with increased serum creatinine following treatment with pantoprazole. Following the end of pantoprazole treatment, short-term RRT and long-term prednisolone was administered, then serum creatinine returned to normal. Pantoprazole-induced acute kidney injury is commonly misdiagnosed and late diagnosis results in poor patient prognoses. Misdiagnosis leads to the administration of treatments that may exacerbate the condition, so appropriate diagnosis and treatment for pantoprazole-induced acute kidney injury is necessary.

Abstract
OBJECTIVE The retention of patients on antiretroviral therapy (ART) is key to achieving global targets in response to the HIV epidemic. Loss to follow-up (LTFU) can be substantial, with unknown outcomes for patients lost to ART programmes. We examined changes in outcomes of patients LTFU over calendar time, assessed associations with other study and programme characteristics and investigated the relative success of different tracing methods. METHODS We performed a systematic review and logistic random-effects meta-regression analysis of studies that traced adults or children who started ART and were LTFU in sub-Saharan African treatment programmes. The primary outcome was mortality, and secondary outcomes were undocumented transfer to another programme, treatment interruption and the success of tracing attempts. RESULTS We included 32 eligible studies from 12 countries in sub-Saharan Africa: 20 365 patients LTFU were traced, and 15 708 patients (77.1%) were found. Compared to telephone calls, tracing that included home visits increased the probability of success: the adjusted odds ratio (aOR) was 9.35 (95% confidence interval [CI] 1.85-47.31). The risk of death declined over calendar time (aOR per 1-year increase 0.86, 95% CI 0.78-0.95), whereas undocumented transfers (aOR 1.13, 95% CI 0.96-1.34) and treatment interruptions (aOR 1.31, 95% CI 1.18-1.45) tended to increase. Mortality was lower in urban than in rural areas (aOR 0.59, 95% CI 0.36-0.98), but there was no difference in mortality between adults and children. The CD4 cell count at the start of ART increased over time. CONCLUSIONS Mortality among HIV-positive patients who started ART in sub-Saharan Africa, were lost to programmes and were successfully traced has declined substantially during the scale-up of ART, probably driven by less severe immunodeficiency at the start of therapy.

Abstract
Introduction While women and girls are disproportionately at risk of HIV acquisition, particularly in low- and middle-income countries (LMIC), globally men and women comprise similar proportions of people living with HIV who are eligible for antiretroviral therapy. However, men represent only approximately 41% of those receiving antiretroviral therapy globally. There has been limited study of men’s outcomes in treatment programmes, despite data suggesting that men living with HIV and engaged in treatment programmes have higher mortality rates. This systematic review (SR) and meta-analysis (MA) aims to assess differential all-cause mortality between men and women living with HIV and on antiretroviral therapy in LMIC. Methods A SR was conducted through searching PubMed, Ovid Global Health and EMBASE for peer-reviewed, published observational studies reporting differential outcomes by sex of adults (≥15 years) living with HIV, in treatment programmes and on antiretroviral medications in LMIC. For studies reporting hazard ratios (HRs) of mortality by sex, quality assessment using Newcastle–Ottawa Scale (cohort studies) and an MA using a random-effects model (Stata 14.0) were conducted. Results A total of 11,889 records were screened, and 6726 full-text articles were assessed for eligibility. There were 31 included studies in the final MA reporting 42 HRs, with a total sample size of 86,233 men and 117,719 women, and total time on antiretroviral therapy of 1555 months. The pooled hazard ratio (pHR) showed a 46% increased hazard of death for men while on antiretroviral treatment (1.35–1.59). Increased hazard was significant across geographic regions (sub-Saharan Africa: pHR 1.41 (1.28–1.56); Asia: 1.77 (1.42–2.21)) and persisted over time on treatment (≤12 months: 1.42 (1.21–1.67); 13–35 months: 1.48 (1.23–1.78); 36–59 months: 1.50 (1.18–1.91); 61 to 108 months: 1.49 (1.29–1.71)). Conclusions Men living with HIV have consistently and significantly greater hazards of all-cause mortality compared with women while on antiretroviral therapy in LMIC. This effect persists over time on treatment. The clinical and population-level prevention benefits of antiretroviral therapy will only be realized if programmes can improve male engagement, diagnosis, earlier initiation of therapy, clinical outcomes and can support long-term adherence and retention.

Abstract
BACKGROUND Community-based models of antiretroviral therapy (ART) delivery are widely discussed as a priority in the expansion of HIV treatment services, but data on their effectiveness are limited. We examined outcomes of ART patients decentralized to community-based adherence clubs (CACs) in Cape Town, South Africa and compared these to patients managed in the community health center. METHODS The analysis included 8150 adults initiating ART from 2002 to 2012 in a public sector service followed until the end of 2013. From June 2012, stable patients (on ART >12 months, suppressed viral load) were referred to CACs. Loss to follow-up (LTFU) was compared between services using proportional hazards models with time-varying covariates and inverse probability weights of CAC participation. FINDINGS Of the 2113 CAC patients (71% female, 7% youth ages ≤ 24 years), 94% were retained on ART after 12 months. Among CAC patients, LTFU [adjusted hazard ratio (aHR): 2.17, 95% confidence interval (CI): 1.26 to 3.73 ] and viral rebound (aHR 2.24, 95% CI: 1.00 to 5.04) were twice as likely in youth (16-24 years old) compared with older patients, but no difference in the risk of LTFU or viral rebound was observed by sex (P-values 0.613 and 0.278, respectively). CAC participation was associated with a 67% reduction in the risk of LTFU (aHR: 0.33, 95% CI: 0.27 to 0.40) compared with community health centre, and this association persisted when stratified by patient demographic and clinic characteristics. INTERPRETATION CACs are associated with reduced risk of LTFU compared with facility-based care. Community-based models represent an important development to facilitate ART delivery and possibly improve patient outcomes.

Abstract
Loss to follow-up (LTFU) is a critical factor in determining clinical outcomes in HIV treatment programs. Identifying modifiable factors of LTFU is fundamental for designing effective patient-retention interventions. We analyzed factors contributing to children LTFU from a treatment program to identify those that can be modified. A case-control study involving 313 children was used to compare the sociodemographic and clinical characteristics of children LTFU (cases) with those remaining in care (controls) at a large pediatric HIV care setting in Botswana. We traced children through caregiver contacts and those we found, we conducted structured interviews with patients' caregivers. Children <5 years were nearly twice as likely as older children to be LTFU (57·8% versus 30·9%, p <0 .01). Approximately half (47·6%, n = 51) of LTFU patients failed to further engage in care after just one clinic visit, as compared to less than 1% (n = 2) in the control group (p < 0.01). Children LTFU were more likely than controls to have advanced disease, greater immunosuppression, and not to be receiving antiretroviral therapy. Among interviewed patient caregivers, psychosocial factors (e.g., stigma, religious beliefs, child rebellion, disclosure of HIV status) were characteristics of patients LTFU, but not of controls. Socioeconomic factors (e.g., lack of transportation, school-related activities, forgetting appointments) were cited predominantly by the controls. Pediatric patients and their caregivers need to be targeted and engaged at their initial clinic visit, with special attention to children <5 years. Possible interventions include providing psychosocial support for issues that deter patients from engaging with The Clinic. Collaboration with community-based organizations focused on reducing stigma may be useful in addressing these complex issues.

Abstract
Religion has substantial - positive and negative - influence on South Africa's HIV context. This qualitative study explored possibilities for positive church engagement in paediatric HIV care in a rural district in Limpopo Province, South Africa. Opinions, attitudes and experiences of various stakeholders including religious leaders, healthcare workers and people infected/affected with/by HIV were investigated through participant observation, semi-structured interviews and focus group discussions. During the research the original focus on paediatric HIV care shifted to HIV care in general in reaction to participant responses. Participants identified three main barriers to positive church engagement in HIV care: (a) stigma and disclosure; (b) sexual associations with HIV and (c) religious beliefs and practices. All participant groups appreciated the opportunity and relevance of strengthening church involvement in HIV care. Opportunities for positive church engagement in HIV care that participants identified included: (a) comprehensive and holistic HIV care when churches and clinics collaborate; (b) the wide social reach of churches and (c) the safety and acceptance in churches. Findings indicate that despite barriers great potential exists for increased positive church engagement in HIV care in rural South Africa. Recommendations include increased medical knowledge and dialogue on HIV/AIDS within church settings, and increased collaboration between churches and the medical sector.

Abstract
BACKGROUND Antiretroviral therapy (ART) initiation is now recommended irrespective of CD4 count. However data on the relationship between CD4 count at ART initiation and loss to follow-up (LTFU) are limited and conflicting. METHODS We conducted a cohort analysis including all adults initiating ART (2008-2012) at three public sector sites in South Africa. LTFU was defined as no visit in the 6 months before database closure. The Kaplan-Meier estimator and Cox's proportional hazards models examined the relationship between CD4 count at ART initiation and 24-month LTFU. Final models were adjusted for demographics, year of ART initiation, programme expansion and corrected for unascertained mortality. RESULTS Among 17 038 patients, the median CD4 at initiation increased from 119 (IQR 54-180) in 2008 to 257 (IQR 175-318) in 2012. In unadjusted models, observed LTFU was associated with both CD4 counts <100 cells/μL and CD4 counts ≥300 cells/μL. After adjustment, patients with CD4 counts ≥300 cells/μL were 1.35 (95% CI 1.12 to 1.63) times as likely to be LTFU after 24 months compared to those with a CD4 150-199 cells/μL. This increased risk for patients with CD4 counts ≥300 cells/μL was largest in the first 3 months on treatment. Correction for unascertained deaths attenuated the association between CD4 counts <100 cells/μL and LTFU while the association between CD4 counts ≥300 cells/μL and LTFU persisted. CONCLUSIONS Patients initiating ART at higher CD4 counts may be at increased risk for LTFU. With programmes initiating patients at higher CD4 counts, models of ART delivery need to be reoriented to support long-term retention.

Abstract
Gastroesophageal reflux (GER) is commonly observed in children, particularly during the first year of life. Pharmacological therapy is mostly reserved for symptomatic infants diagnosed with GER disease (GERD), usually as defined in a recent consensus statement. The purpose of the present article was to review the reported adverse effects of pharmacological agents used in the treatment of paediatric GERD. We conducted this review using the electronic journal database Pubmed and Cochrane database systematic reviews using the latest 10-year period (1 January 2003 to 31 December 2012). Our search strategy included the following keywords: omeprazole, esomeprazole, lansoprazole, pantoprazole, rabeprazole, rantidine, cimetidine, famotidine, nizatidine, domperidone, metoclopramide, betanechol, erythromycin, baclofen, alginate. We used Pubmed's own filter of: 'child: birth-18 years'. All full articles were reviewed and we only included randomized controlled trials retrieved from our search. We addressed a summary of our search on a drug-by-drug basis with regard to its mechanism of action and clinical applications, and reviewed all of the adverse effects reported and the safety profile of each drug. Adverse effects have been reported in at least 23% of patients treated with histamine H2 receptor antagonists (H2 RAs) and 34% of those treated with proton pump inhibitors (PPIs), and mostly include headaches, diarrhoea, nausea (H2 RAs and PPIs) and constipation (PPIs). Acid suppression may place immune-deficient infants and children, or those with indwelling catheters, at risk for the development of lower respiratory tract infections and nosocomial sepsis. Prokinetic agents have many adverse effects, without major benefits to support their routine use.

Implementation of community-based adherence clubs for stable antiretroviral therapy patients in Cape Town, South Africa. J Int AIDS Soc 2015; 18:19984. [PMID: 26022654 PMCID: PMC4444752 DOI: 10.7448/ias.18.1.19984] [Citation(s) in RCA: 97] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2014] [Revised: 03/13/2015] [Accepted: 04/22/2015] [Indexed: 01/25/2023] Open
Abstract
Introduction Community-based models of antiretroviral therapy (ART) delivery have been recommended to support ART expansion and retention in resource-limited settings. However, the evidence base for community-based models of care is limited. We describe the implementation of community-based adherence clubs (CACs) at a large, public-sector facility in peri-urban Cape Town, South Africa. Methods Starting in May 2012, stable ART patients were down-referred from the primary care community health centre (CHC) to CACs. Eligibility was based on self-reported adherence, >12 months on ART and viral suppression. CACs were facilitated by four community health workers and met every eight weeks for group counselling, a brief symptom screen and distribution of pre-packed ART. The CACs met in community venues for all visits including annual blood collection and clinical consultations. CAC patients could send a patient-nominated treatment supporter (“buddy”) to collect their ART at alternate CAC visits. Patient outcomes [mortality, loss to follow-up and viral rebound (>1000 copies/ml)] during the first 18 months of the programme are described using Kaplan–Meier methods. Results and Discussion From June 2012 to December 2013, 74 CACs were established, each with 25–30 patients, providing ART to 2133 patients. CAC patients were predominantly female (71%) and lived within 3 km of the facility (70%). During the analysis period, 9 patients in a CAC died (<0.1%), 53 were up-referred for clinical complications (0.3%) and 573 CAC patients sent a buddy to at least one CAC visit (27%). After 12 months in a CAC, 6% of patients were lost to follow-up and fewer than 2% of patients retained experienced viral rebound. Conclusions Over a period of 18 months, a community-based model of care was rapidly implemented decentralizing more than 2000 patients in a high-prevalence, resource-limited setting. The fundamental challenge for this out of facility model was ensuring that patients receiving ART within a CAC were viewed as an extension of the facility and part of the responsibility of CHC staff. Further research is needed to support down-referral sooner after ART initiation and to describe patient experiences of community-based ART delivery.

Abstract
BACKGROUND Academic Model Providing Access To Healthcare (AMPATH) program provides comprehensive HIV care and treatment services. Approximately, 30% of patients have become lost to follow-up (LTFU). We sought to actively trace and identify outcomes for a sample of these patients. METHODS LTFU was defined as missing a scheduled visit by ≥3 months. A randomly selected sample of 17% of patients identified as LTFU between January 2009 and June 2011 was generated, with sample stratification on age, antiretroviral therapy (ART) status at last visit, and facility. Chart reviews were conducted followed by active tracing. Tracing was completed by trained HIV-positive outreach workers July 2011 to February 2012. Outcomes were compared between adults and children and by ART status. RESULTS Of 14,811 LTFU patients, 2540 were randomly selected for tracing (2179 adults, 1071 on ART). The chart reviews indicated that 326 (12.8%) patients were not actually LTFU. Outcomes for 71% of sampled patients were determined including 85% of those physically traced. Of those with known outcomes, 21% had died, whereas 29% had disengaged from care for various reasons. The remaining patients had moved away (n = 458, 25%) or were still receiving HIV care (n = 443 total, 25%). CONCLUSIONS Our findings demonstrate the feasibility of a large-scale sampling-based approach. A significant proportion of patients were found not to be LTFU, and further, high numbers of patients who were LTFU could not be located. Over a quarter of patients disengaged from care for various reasons including access challenges and familial influences.

Abstract
OBJECTIVE To ascertain estimates of adult patients, recorded as lost to follow-up (LTFU) within antiretroviral treatment (ART) programmes, who have self-transferred care, died or truly stopped ART in low- and middle-income countries. METHODS PubMed, EMBASE, Web of Science, Science Direct, LILACS, IndMed and AIM databases (2003-2013) and IAS/AIDS conference abstracts (2011-2013) were searched for tracing studies reporting the proportion of traced patients found to have self-transferred, died or stopped ART. These estimates were then combined using random-effects meta-analysis. Risk of bias was assessed through subgroup and sensitivity analyses. RESULTS Twenty eight studies were eligible for inclusion, reporting true outcomes for 10,806 traced patients attending approximately 258 ART facilities. None were from outside sub-Saharan Africa. Twenty three studies reported 4.5-54.4% traced LTFU patients self-transferring care, providing a pooled estimate of 18.6% (95% CI 15.8-22.0%). A significant positive association was found between rates of self-transfer and LTFU in the ART cohort. The pooled estimates for unreported deaths were 38.8% (95% CI 30.8-46.8%; 27 studies) and 28.6% (95% CI 21.9-36.0%; 20 studies) for patients stopping ART. A significant decrease in unreported deaths from 50.0% (95% CI 41.5-58.4%) to 30.0% (95% CI 21.1-38.9%) was found comparing study periods before and after 31 December 2007. CONCLUSIONS Substantial unaccounted for transfers and deaths amongst patients LTFU confirms that retention and mortality is underestimated where the true outcomes of LTFU patients are not ascertained.

Abstract
BACKGROUND Socioeconomic support reduced nonretention in a community-based antiretroviral therapy (ART) program in Uganda. However, resource implications of expanding socioeconomic support are large, and cost-effectiveness analysis can inform budget priorities. We compared the incremental benefits and costs of providing education, food, or both forms of support (dual support) with existing ART services from a health care provider's perspective. METHODS Costs and outcome data were collected from a cohort of 2371 adult patients with HIV receiving education, food, or dual support from Reach Out Mbuya between 2004 and 2010. The primary outcome was averted loss to follow-up. The number of follow-up days was calculated for each patient along with accrued service and fixed program costs for the alternative forms of socioeconomic support in USD by standard costing methods. The socioeconomic support types were compared incrementally over the study period. RESULTS After 7 years, 762 (33%) of the patients were loss to follow-up with 42% of them receiving food. In the presence of providing ART, education support was less costly and more effective than the alternatives. The average unit cost for education, food, and dual support were $237, $538, and $776, respectively. The average total annual costs were $88,643 for education, $538,005 for food, and $103,045 for dual support. CONCLUSIONS Compared with food or dual support, investing in education of the children of ART patients is less costly and more effective in improving patient retention. Reach Out Mbuya should embrace this paradigm shift and channel its resources more efficiently and effectively by focusing on education support.

Abstract
SETTING Namibia faces a high burden of tuberculosis (TB) and HIV-infection. In 2011, 50% of the TB patients were co-infected with HIV. While all patients co-infected with TB and HIV are eligible for antiretroviral treatment (ART), only 54% were reported to have received ART according to national data. OBJECTIVE To explore the perspective of healthcare professionals on barriers to access to ART for HIV-positive TB patients. DESIGN Nine semi-structured qualitative interviews were conducted with healthcare professionals from TB and HIV services in Windhoek in 2012 to investigate access barriers to ART for HIV-positive TB patients in Namibia. RESULTS Many barriers known from other African countries were also present in Namibia. The barriers rated as most important were: staff shortage (health system level); limited training (healthcare worker level); and fear of stigma and discrimination (patient/community level). Direct treatment costs and limited availability of antiretroviral medication were not observed as barriers. Interference with TB treatment and ART by some Pentecostal churches was revealed as an important barrier that has not yet received sufficient attention. CONCLUSION The study identified access barriers to ART for HIV-positive TB patients and their relevance in Namibia. The findings provide evidence for tailored interventions to increase ART-uptake among HIV-positive TB patients.

Follow-Up Visit Patterns in an Antiretroviral Therapy (ART) programme in Zomba, Malawi. PLoS One 2014; 9:e101875.

Abstract
Background Identifying follow-up (FU) visit patterns, and exploring which factors influence them are likely to be useful in determining which patients on antiretroviral therapy (ART) may become Lost to Follow-Up (LTFU). Using an operation and implementation research approach, we sought 1) to describe the timing of FU visits amongst patients who have been on ART for shorter and longer periods of time; and 2) to determine the median time to late visits, and 3) to identify specific factors that may be associated with these patterns in Zomba, Malawi. Methods and Findings Using routinely collected programme monitoring data from Zomba District, we performed descriptive analyses on all ART visits among patients who initiated ART between Jan. 1, 2007–June 30, 2010. Based on an expected FU date, each FU visit was classified as early (≥4 day before an expected FU date), on time (3 days before an expected FU date/up to 6 days after an expected FU date), or late (≥7 days after an expected FU date). In total, 7,815 patients with 76417 FU visits were included. Ninety-two percent of patients had ≥2 FU visits. At the majority of visits, patients were either on time or late. The median time to a first late visit among those with 2 or more visits was 216 days (IQR: 128–359). Various patient- and visit-level factors differed significantly across Early, On Time, and Late visit groups including ART adherence and frequency of, and type of side effects. Discussion The majority of patients do not demonstrate consistent FU visit patterns. Individuals were generally on ART for at least 6 months before experiencing their first late visit. Our findings have implications for the development of effective interventions that meet patient needs when they present early and can reduce patient losses to follow-up when they are late. In particular, time-varying visit characteristics need further research.

Abstract
OBJECTIVES Models of care utilizing task shifting and decentralization are needed to support growing ART programmes. We compared patient outcomes between a doctor-managed clinic and a nurse-managed down-referral site in Cape Town, South Africa. METHODS Analysis included all adults who initiated ART between 2002 and 2011 within a large public sector ART service. Stable patients were eligible for down-referral. Outcomes [mortality, loss to follow-up (LTFU), virologic failure] were compared under different models of care using proportional hazards models with time-dependent covariates. RESULTS Five thousand seven hundred and forty-six patients initiated ART and over 5 years 41% (n = 2341) were down-referred; the median time on ART before down-referral was 1.6 years (interquartile range, 0.9-2.6). The nurse-managed down-referral site reported lower crude rates of mortality, LTFU and virologic failure compared with the doctor-managed clinic. After adjustment, there was no difference in the risk of mortality or virologic failure by model of care. However, patients who were down-referred were more likely to be LTFU than those retained at the doctor-managed site (adjusted hazard ratio, 1.36; 95% CI, 1.09-1.69). Increased levels of LTFU in the nurse-managed vs. doctor-managed service were observed in subgroups of male patients, those with advanced disease at initiation and those who started ART in the early years of the programme. CONCLUSION Reorganization of ART maintenance by down-referral to nurse-managed services is associated with programme outcomes similar to those achieved using doctor-driven primary care services. Further research is necessary to identify optimal models of care to support long-term retention of patients on ART in resource-limited settings.

Abstract
To determine the optimal time to track patients, we evaluated the outcomes of patients traced after missing their return visits at 3 periods, 8, 30, or 90 days, at the Infectious Diseases Clinic in Kampala, Uganda. During the study period from January to December 2011, the proportion of untraceable patients was 2 (4%) after 8 days, 12 (10%) after 30 days, and 13 (15%) after 90 days. More than 75% of the patients who died had a CD4 count of <200 cells/mm(3) at their last visit. In conclusion, tracking patients after 1 week of a missed return visit should be the preferred method of tracking. If resources are limited, patients with CD4 counts <200 cells/mm(3) need to be targeted for tracking, as they are most at risk of dying if they interrupt treatment.

Abstract
We determined the retention rate of patients infected with HIV who resumed care after being tracked at the Infectious Diseases Clinic (IDC) in Kampala, Uganda. Between April 2011 and September 2013, patients who missed their clinic appointment for 8-90 days were tracked, and those who returned to the clinic within 120 days were followed up. The proportion of patients retained among tracked patients, and those who resumed care before tracking started was compared. At 18 months of follow up, 33 (39%) of the tracked patients and 72 (61%) of those who had resumed care before tracking started were retained in care. The most important cause of attrition among the traceable was self-transfer to another clinic (38 [73%] patients), whereas among those who resumed care before tracking was loss to follow up (LTFU) (32 [71%] patients). Tracked patients who resume care following a missed appointment are at high risk of attrition. To increase retention, antiretroviral therapy clinics need to adopt a chronic care model which takes into consideration patients' changing needs and their preference for self-management.

Abstract
BACKGROUND The purpose of this case-control study was to identify risk factors for loss to follow-up (LTFU). METHODS Cases and controls were selected from HIV-positive patients, aged 18 years and older, on antiretroviral therapy (ART) at the Infectious Diseases Clinic (IDC) in January 2008. As cases, we selected 209 patients who in 2008 did not return to the clinic within 90 days of their scheduled appointment date. As controls, we randomly selected 626 patients from the 5872 patients who were following up at the end of December 2008. RESULTS In multivariable logistic regression analysis, urban or semiurban residence, World Health Organization disease stage III or IV at ART initiation, a median CD4 count at last visit <200 cells/mm(3), tuberculosis (TB) in the 6 months before the last visit, absence of counseling before ART initiation, and no disclosure of HIV status were associated with LTFU. CONCLUSION This study demonstrates the importance of close patient monitoring in advanced stages of disease, supportive counseling for patients initiating ART, extra psychosocial support for patients with TB and HIV coinfection, assisting patients with disclosure, and setting up a good referral system to retain patients on ART.

Abstract
Background Optimized preventive strategies are needed to reach the objective of eliminating pediatric AIDS. This study aimed to define the determinants of residual HIV transmission in the context of maternal antiretroviral therapy (ART) administration to pregnant women, to assess infant safety of this strategy, and to evaluate its impact on maternal disease. Methodology/Principal Findings A total of 311 HIV-infected pregnant women were enrolled in Malawi in an observational study and received a nevirapine-based regimen from week 25 of gestation until 6 months after delivery (end of breastfeeding period) if their CD4+ count was > 350/mm3 at baseline (n = 147), or indefinitely if they met the criteria for treatment (n. 164). Mother/child pairs were followed until 2 years after delivery. The Kaplan-Meier method was used to estimate HIV transmission, maternal disease progression, and survival at 24 months. The rate of HIV infant infection was 3.2% [95% confidence intervals (CI) 1.0-5.4]. Six of the 8 transmissions occurred among mothers with baseline CD4+ count > 350/mm3. HIV-free survival of children was 85.8% (95% CI 81.4-90.1). Children born to mothers with baseline CD4+ count < 350/mm3 were at increased risk of death (hazard ratio 2.6, 95% CI 1.1-6.1). Among women who had stopped treatment the risk of progression to CD4+ count < 350/mm3 was 20.6% (95% CI 9.2-31.9) by 18 months of drug discontinuation. Conclusions HIV transmission in this cohort was rare however, it occurred in a significative proportion among women with high CD4+ counts. Strategies to improve treatment adherence should be implemented to further reduce HIV transmission. Mortality in the uninfected exposed children was the major determinant of HIV-free survival and was associated to maternal disease stage. Given the considerable proportion of women reaching the criteria for treatment within 18 months of drug discontinuation, life-long ART administration to HIV-infected women should be considered.

Abstract
BACKGROUND The purpose of this study was to assess patients' experience and satisfaction with pharmacy-only refill program (PRP) and to compare those who were removed from the PRP with those still in the program. METHODS A sample of 446 patients was selected from 1503 patients on antiretroviral therapy that had been enrolled in the PRP for at least 24 months. The study used interviewer-administered questionnaires to assess patients' experience and satisfaction with PRP. RESULTS Of the 446 patients, 133 (29.8%) were removed from the PRP. By multivariate analysis, it was found that wanting to see a clinician before their scheduled clinic visit, Christian religion, and not understanding why they were enrolled in PRP were associated with having been removed from the PRP. Patients felt that the greatest benefit from the program was the time that they saved to do other activities. Patients preferred to collect their medication every 3 months instead of every month. CONCLUSION All patients interviewed scored the program high, and all recommended that the PRP should continue. Stable patients prefer to see clinicians less frequently and visit clinic less often.

Toward an understanding of disengagement from HIV treatment and care in sub-Saharan Africa: a qualitative study. PLoS Med 2013; 10:e1001369; discussion e1001369.

Abstract
BACKGROUND The rollout of antiretroviral therapy in sub-Saharan Africa has brought lifesaving treatment to millions of HIV-infected individuals. Treatment is lifelong, however, and to continue to benefit, patients must remain in care. Despite this, systematic investigations of retention have repeatedly documented high rates of loss to follow-up from HIV treatment programs. This paper introduces an explanation for missed clinic visits and subsequent disengagement among patients enrolled in HIV treatment and care programs in Africa. METHODS AND FINDINGS Eight-hundred-ninety patients enrolled in HIV treatment programs in Jos, Nigeria; Dar es Salaam, Tanzania; and Mbarara, Uganda who had extended absences from care were tracked for qualitative research interviews. Two-hundred-eighty-seven were located, and 91 took part in the study. Interview data were inductively analyzed to identify reasons for missed visits and to assemble them into a broader explanation of how missed visits may develop into disengagement. Findings reveal unintentional and intentional reasons for missing, along with reluctance to return to care following an absence. Disengagement is interpreted as a process through which missed visits and ensuing reluctance to return over time erode patients' subjective sense of connectedness to care. CONCLUSIONS Missed visits are inevitable over a lifelong course of HIV care. Efforts to prevent missed clinic visits combined with moves to minimize barriers to re-entry into care are more likely than either approach alone to keep missed visits from turning into long-term disengagement.
