Clinical effectiveness of ferric carboxymaltose (iv) versus iron sucrose (iv) in treatment of iron deficiency anaemia in pregnancy: A systematic review and meta-analysis.

BACKGROUND OBJECTIVES: Iron deficiency anaemia (IDA) during pregnancy is treated with oral and parenteral iron. The objective of this review was to compare the clinical effectiveness, safety, pregnancy and neonatal outcomes of intravenous (iv) ferric carboxymaltose (FCM) and iv iron sucrose (IS) in treating IDA in pregnancy. METHODS: The Department of Health Research funded this study. PubMed, Cochrane Library, EMBASE and Scopus were searched to include studies published till November 2022. The protocol was registered in PROSPERO (CRD42022306092). Pregnant women (15-49 yr) in second and third trimesters, diagnosed with moderate-to-severe iron deficiency anaemia, treated with either of the drugs were included. The included studies were critically assessed using appropriate tools. We conducted a qualitative synthesis of the studies and meta-analysis for improvement in haematological parameters and incidence of adverse events. RESULTS: A total of 18 studies were included. The risk of bias was low to moderate. A rise in haemoglobin up to four weeks was higher with FCM than IS by 0.57 (0.24, 0.9) g/dl. Intravenous FCM is associated with fewer adverse events than IS [pooled odds ratio: 0.5 (0.32, 0.79)]. The included studies had limited evidence on pregnancy and neonatal outcomes after iv iron treatment. INTERPRETATION CONCLUSIONS: Intravenous FCM is effective and safer than intravenous IS in terms of haematological parameters, in treating IDA in pregnancy. Further research is required on the effects of iv FCM and iv IS on the pregnancy and neonatal outcomes when used for treating IDA in pregnancy.

Health facility-based interventions and the uptake of contraception among people living with HIV: A systematic review & meta-analysis.

BACKGROUND OBJECTIVES: The prong 2 of 4 prong strategy introduced by the World Health Organization aims at averting unintended pregnancies among people living with HIV (PLHIV). This systematic review aimed to generate evidence on the effectuality of facility-based interventions in improving uptake of modern and dual contraception, for reducing unmet family planning (FP) needs and unintended pregnancies among PLHIV. METHODS: Articles evaluating facility-based interventions to integrate human immunodeficiency virus (HIV) and FP published in English language were included. Eligible studies were identified from electronic and lateral search from three databases (PubMed, Cochrane Library and Web of Science) and grey literature. HIV care with no/minimal focus on FP was considered a comparator. Quality was assessed using design-appropriate tools. Descriptive analysis was presented in tables. Uptake of dual methods, unmet FP needs and unintended pregnancies were included in the meta-analysis to estimate pooled odds ratio (OR) with random effect model, P and I2 values. RESULTS: The search yielded 2112 results. After excluding duplicates and unfit articles, 17 were found eligible for review and nine for meta-analysis. The pooled OR for uptake of dual contraception was 1.69 (1.14, 2.5) ( P =0.008; I2 =90%), for unmet FP needs was 0.58 (0487, 0.69) ( P <0.00001; I2 =0%) and for unintended pregnancies was 0.6 (0.32, 1.1) ( P =0.1, I2 =38%). INTERPRETATION CONCLUSIONS: The results of this meta-analysis suggest that health facility-based interventions to integrate HIV and FP services do result in improved uptake of dual methods and reduce unmet need for contraception along with a protective trend on incidence of unintended pregnancies. Such facility-based integration would ensure universal access to effective contraception and facilitate in achieving Sustainable Development Goals that aim at ending epidemics like HIV.

Health system cost for providing antiretroviral therapy, family planning, and pregnancy-related services to women living with HIV in public health settings, Mumbai, India.

Background: Integration of HIV care into family planning (FP) services would help in reducing unintended pregnancies among women living with HIV. Objectives: This study focuses on determining the health system cost for providing the linked HIV-FP services per beneficiary for the year 2019-2020. Materials and Methods: Using mixed micro-costing approach costs were collected from two tertiary hospitals in Maharashtra, India. The economic costs collected from gynaecology department and anti-retroviral treatment center were combined and added with package, program, and intervention costs to obtain health-system costs. We conducted probabilistic sensitivity analysis. Results: The unit cost and annual per-capita cost for providing HIV care (without considering cost of drugs and investigations) per beneficiary were INR 1033.8 (USD 13.6) and INR 9304.2 (USD 122.7), respectively. The unit cost was least for the outpatient services INR 197.5 (USD 2.6), followed by inpatient services INR 2735.92 (USD 36.21) and operation theater INR 4410 (USD 58.2). Cost was highest for dual-permanent (INR 13866.8 [USD 182.9]) followed by dual-reversible user (INR 2104.8 [USD 24.8]). It was the least for a person who only used condoms at INR 1674.1 (USD 22.1). In pregnancy-related services, cost for ante-natal services was least (INR 2043.6 [USD 27.96]), followed by vaginal delivery (INR 7120.5 [USD 93.93]), abortion (INR 11530.5 [USD 152.097]), and C-section (INR 18703.8 [USD 246.7]). Conclusion: We found no staggeringly additional costs for providing FP and pregnancy-related services to HIV-affected population, in comparison to general population. The findings could improve programs and insurance with a focus on this vulnerable population.

Diarrheal Etiology and Impact of Coinfections on Rotavirus Vaccine Efficacy Estimates in a Clinical Trial of a Monovalent Human-Bovine (116E) Oral Rotavirus Vaccine, Rotavac, India.

BACKGROUND: Rotavirus vaccine efficacy (VE) estimates in low-resource settings are lower than in developed countries. We detected coinfections in cases of severe rotavirus diarrhea in a rotavirus VE trial to determine whether these negatively impacted rotavirus VE estimates. METHODS: We performed TaqMan Array Card assays for enteropathogens on stools from rotavirus enzyme immunoassay-positive diarrhea episodes and all severe episodes (Vesikari score ≥11), from a phase 3 VE trial of Rotavac, a monovalent human-bovine (116E) rotavirus vaccine, carried out across 3 sites in India. We estimated pathogen-specific etiologies of diarrhea, described associated clinical characteristics, and estimated the impact of coinfections on rotavirus VE using a test-negative design. RESULTS: A total of 1507 specimens from 1169 infants were tested for the presence of coinfections. Rotavirus was the leading cause of severe diarrhea even among vaccinated children, followed by adenovirus 40/41, Shigella/enteroinvasive Escherichia coli, norovirus GII, sapovirus, and Cryptosporidium species. Bacterial coinfections in rotavirus-positive diarrhea were associated with a longer duration of diarrhea and protozoal coinfections with increased odds of hospitalization. Using the test-negative design, rotavirus VE against severe rotavirus gastroenteritis increased from 49.3% to 60.6% in the absence of coinfections (difference, 11.3%; 95% confidence interval, -10.3% to 30.2%). CONCLUSIONS: While rotavirus was the dominant etiology of severe diarrhea even in vaccinated children, a broad range of other etiologies was identified. Accounting for coinfections led to an 11.3% increase in the VE estimate. Although not statistically significant, an 11.3% decrease in VE due to presence of coinfections would explain an important fraction of the low rotavirus VE in this setting.

Enteropathogens and Gut Inflammation in Asymptomatic Infants and Children in Different Environments in Southern India.

Children in poor environmental conditions are exposed early and often to enteric pathogens, but within developing countries, heterogeneity in enteropathogen exposure in different settings and communities is rarely addressed. We tested fecal samples from healthy infants and children from two different environments in the same Indian town for gut enteropathogens and biomarkers of gut inflammation. A significantly higher proportion of infants and children from a poor semi-urban neighborhood (93%) had one or more enteropathogens than those from a medical college campus (71.7%). Infants and children from the poor neighborhood had an average of 3.3 (95% confidence interval [CI]: 2.9-3.7) enteropathogens compared with an average of 1.4 (95% CI: 1.0-1.7) enteropathogens in campus infants/children. Viral and bacterial infections, including enteroviruses, adenoviruses, Campylobacter spp., and diarrhegenic Escherichia coli were more common and fecal biomarkers of inflammation were higher in the poor neighborhood. The findings demonstrate significant difference in the asymptomatic carriage of gut enteropathogens and gut inflammatory biomarkers in infants and children from two different environments within the same town in south India.

Influence of limonin on Wnt signalling molecule in HepG2 cell lines.

OBJECTIVE: The role of limonin as potent anti carcinogenic, apoptosis and chemotherapeutic agents has been supported by limited studies. MATERIALS AND METHODS: In this study, limonin is identified as a potent anti proliferative agent against human hepatoma HepG2 cells based on the cell viability study, LDH leakage assay. Induction of apoptosis in HepG2 cells by limonin was evidenced by western blot analysis of Bax, Cyclin D1, Caspase 3 and Caspase9. RESULTS: Since Wnt signalling is involved in the initiation and sustaining of hepatocellular carcinoma we studied differential expression of LRP5, LRP6 and DKK wnt players. CONCLUSION: Limonin found to down regulate these players which forms a rationale for further investigation on effect on limonin in cancer therapy.

Acanthamoeba keratitis - a six year epidemiological review from a tertiary care eye hospital in south India.

PURPOSE: This study analyses the prevalence, demography, predisposing factors and seasonal variation of Acanthamoeba keratitis. METHODS: A retrospective review of all cases presenting with keratitis at the cornea clinic, Aravind Eye Hospital, Coimbatore, from August 1997 to July 2003, was done for screening patients with a provisional diagnosis of Acanthamoeba keratitis. Their records were further analyzed for microbiological details. Cases with culture proven Acanthamoeba keratitis were included for epidemiological analysis. RESULTS: From a total of 4519 patients who attended cornea clinic 32 (33 eyes) patients were confirmed to be positive for Acanthamoeba keratitis. Twenty cases (62.5%) were males. Majority (18; 54.2%) of the Acanthamoeba keratitis eyes reported corneal trauma by solid objects. No peak period was observed in a year, as the number of cases was almost uniform in all months. CONCLUSION: This study indicates the increasing prevalence of Acanthamoeba keratitis among non-contact lens users in this region during the 6-year period.
