Severe anaemia is a major cause of morbidity and mortality in HIV-infected adults living in resource-limited countries. Comprehensive data on the aetiology are lacking but are needed to improve ...outcomes.
HIV-infected adults with severe (haemoglobin ≤70g/l) or very severe anaemia (haemoglobin ≤ 50 g/l) were recruited at Queen Elizabeth Central Hospital, Blantyre, Malawi. Fifteen potential causes and associations with anaemia severity and mortality were explored.
199 patients were enrolled: 42.2% had very severe anaemia and 45.7% were on ART. More than two potential causes for anaemia were present in 94% of the patients including iron deficiency (55.3%), underweight (BMI<20: 49.7%), TB infection (41.2%) and unsuppressed HIV infection (viral load >1000 copies/ml) (73.9%). EBV/CMV co-infection (16.5%) was associated with very severe anaemia (OR 2.8 95% CI 1.1-6.9). Overall mortality was high (53%; 100/199) with a median time to death of 17.5 days (IQR 6-55) days. Death was associated with folate deficiency (HR 2.2; 95% CI 1.2-3.8) and end stage renal disease (HR 3.2; 95% CI 1.6-6.2).
Mortality among severely anaemic HIV-infected adults is strikingly high. Clinicians should be aware of the urgent need for a multifactorial approach including starting or optimising HIV treatment, considering TB treatment, nutritional support and optimising renal management.
Iron deficiency is a treatable cause of severe anaemia in low-and-middle-income-countries (LMIC). Diagnosing it remains challenging as peripheral blood markers poorly reflect bone-marrow iron ...deficiency (BM-ID), especially in the context of HIV-infection.
Severely anaemic (haemoglobin ≤70g/l) HIV-infected adults were recruited at Queen Elizabeth Central Hospital, Blantyre, Malawi. BM-ID was evaluated. Accuracy of blood markers (including hepcidin, mean corpuscular volume, mean cellular haemoglobin concentration, serum iron, serum ferritin, soluble transferrin receptor (sTfR), sTfR index, sTfR-ratio) to detect BM-ID was evaluated by ROC area under the curve (AUCROC).
Seventy-three patients were enrolled and 35 (48.0%) had BM-ID. Although hepcidin and MCV performed best (AUCROC of 0.593 and 0.545 respectively) all markers performed poorly in identifying BM-ID (ROC<0.6). The AUCROC of hepcidin in males was 0.767 (sensitivity 80%, specificity 78%) and in women 0.490 (sensitivity 60%, specificity 61%).
BM-ID deficiency was common in severely anaemic HIV-infected patients. It is an important and potential treatable contributor to severe anaemia but lack of definitive biomarkers makes it difficult to accurately assess iron status in these patients. Further investigation of the potential of hepcidin is needed, including exploration of the differences in hepcidin results between males and females.
Perinatally chikungunya infected neonates have been reported to have high rates of post-infection neurologic sequelae, mainly cognitive problems. In older children and adults chikungunya does not ...appear to have sequelae, but data on postnatally infected infants are lacking.
We performed a prospective, non-controlled, observational study of infants infected before the age of 6 months with a severe chikungunya infection during the 2014-2015 epidemic in Curaçao, Dutch Antilles. Two years post-infection cognitive and motor - (BSID-III) and social emotional assessments (ITSEA) were performed.
Of twenty-two infected infants, two died and two were lost to follow up. Eighteen children were seen at follow-up and included in the current study. Of these, 13 (72%) had abnormal scores on the BSID-III (cognitive/motor) or ITSEA.
In the first study aimed at postnatally infected infants, using an uncontrolled design, we observed a very high percentage of developmental problems. Further studies are needed to assess causality, however until these data are available preventive measure during outbreaks should also include young infants. Those that have been infected in early infancy should receive follow up.
Malnutrion among children with childhood cancer in low and middle income countries (LMICs) is prevelant. While national nutrition programs focus on children under 5 years, childhood cancer can occur ...regardless of their age. Through a single-center retrospective cohort in Lilongwe, Malawi, we aim to characterize the burden of age-related malnutrition among children diagnosed with cancer in Lilongwe, Malawi, and evaluate them for any associations with mortality. Four hundred and sixty-three children (63.5% ≥5 years and 58.3% males) were identified.The majority of children (63.3%) were malnourished; 23.1% had moderate acute malnutrition (MAM) and 40.2% had severe acute malnutrition (SAM). Malnutrition was more common in children ≥5 years (70.0%) compared to children <5 years (51.8%); p < 0.0001. Age <5 years (HR 1.6; 95%CI 1.1-2.3, p = 0.016) and presence of sever acute malnutrition (HR 1.6, 95%CI 1.1-2.3, p = 0.012) were both associated with increased mortality risk. Acute malnutrition was highly prevalent among children with cancer above 5 years of age. This age group is not prioritized among malnutrition programs in LMICs, hence there is a direct need to include children with cancer regardless of age in national nutrition guidelines in LMICs to give them acces to adequate nutritional support.
Objectives
This systematic review provides an overview of the effect of undernutrition on the pharmacokinetics of chemotherapy in children with cancer.
Methods
PubMed, Embase, and Cochrane were ...searched to identify eligible studies. This study uses the definition for undernutrition from the World Health Organization and the Gomez classification.
Results
Four studies with a total of 668 children with cancer were included and n = 121 (18%) were undernourished. Significant decreased clearance rates were found for vincristine in undernourished children compared to children with a normal nutritional status.
Conclusion
Presenting outcomes only show significant changes in the pharmacokinetics of vincristine in undernourished children with cancer. However, data are scarce, groups were small, and none of the studies included severely undernourished children. In order to improve outcomes for (severely) undernourished children with cancer, more pharmacokinetic research is needed. The ultimate goal would be to develop subgroups, and ultimately individualized drug dosing in order to improve outcomes for children with cancer worldwide.
Introduction
Wilms tumor therapy in low‐ and middle‐income countries (LMICs) relies on treatment protocols adapted to resource limitations, but these protocols have rarely been evaluated in ...real‐world settings. Such evaluations are necessary to identify high‐impact research priorities for clinical and implementation trials in LMICs. The purpose of this study was to identify highest priority targets for future clinical and implementation trials in sub‐Saharan Africa by assessing outcomes of a resource‐adapted treatment protocol in Malawi.
Methods
We conducted a retrospective cohort study of children treated for Wilms tumor with an adapted SIOP‐backbone protocol in Lilongwe, Malawi between 2016 and 2021. Survival analysis assessed variables associated with poor outcome with high potential for future research and intervention.
Results
We identified 136 patients, most commonly with stage III (n = 35; 25.7%) or IV disease (n = 35; 25.7%). Two‐year event‐free survival (EFS) was 54% for stage I/II, 51% for stage III, and 13% for stage IV. A single patient with stage V disease survived to 1 year. Treatment abandonment occurred in 36 (26.5%) patients. Radiotherapy was indicated for 55 (40.4%), among whom three received it. Of these 55 patients, 2‐year EFS was 31%. Of 14 patients with persistent metastatic pulmonary disease at the time of nephrectomy, none survived to 2 years. Notable variables independently associated with survival were severe acute malnutrition (hazard ratio HR: 1.9), increasing tumor stage (HR: 1.5), and vena cava involvement (HR: 3.1).
Conclusion
High‐impact targets for clinical and implementation trials in low‐resource settings include treatment abandonment, late presentation, and approaches optimized for healthcare systems with persistently unavailable radiotherapy.
Intestinal protozoa are common opportunistic infections in HIV patients. Longitudinal studies on either the clinical relevance or the effect of immune reconstitution by antiretroviral therapy on ...intestinal protozoan infections in children are lacking however. This study investigates prevalence and clinical relevance of intestinal protozoa in HIV-infected Malawian children before and during their first year of antiretroviral treatment (ART).
Stool samples collected at enrolment and during follow-up were tested for nonopportunistic (Giardia lamblia, Dientamoeba fragilis, Entamoeba histolytica) and opportunistic protozoa (Enterocytozoon bieneusi, Encephalitozoon spp., Cryptosporidium spp. and Cystoisospora belli) using multiplex real-time polymerase chain reaction. Associations between infections and clinical symptoms were evaluated using univariate methods.
Nonopportunistic and opportunistic protozoa were detected in 40% (14/35) and 46% (16/35) of children at baseline, respectively. E. bieneusi was the most prevalent protozoa (37%, 13/35) and associated with gastrointestinal complaints (43% in positive (10/13) versus 18% (4/22) in E. bieneusi-negative children, P = 0.001. Body mass index recovery during 12 months of ART was more commonly delayed in E. bieneusi-positive children (+0.29 +standard deviation 0.83) than E. bieneusi-negative children (+1.03 +standard deviation 1.25; P = 0.05). E. bieneusi was not detected after 12 months of ART.
E. bieneusi was the most prevalent opportunistic intestinal protozoa, present in over a third of study participants before initiation of ART. Although all children cleared E. bieneusi after 12 months of ART, E. bieneusi was associated with gastrointestinal complaints and may delay body mass index recovery. Trials to assess effect of treatment of E. bieneusi on nutritional status should be considered in HIV-infected African children.
Outcomes for children with cancer in sub-Saharan Africa (SAA) are dismal due to delayed diagnosis and limited access to curative therapy. When establishing a pediatric hematology-oncology (PHO) ...program in low-resource settings, early integration of palliative care services becomes essential. While palliative care is a human right, equitable distribution is lacking.
We aim to describe our experience establishing a palliative care program, the services offered, and the distribution of patients served.
This is a brief description of our PHO palliative care program in Lilongwe, Malawi at a tertiary care center and a three-year retrospective review of activities (2017–2020). Services offered include inpatient, outpatient, home visits, end of life care, and strengthening of referral systems.
Over the three-year period, 315 patients were enrolled. 57% (n=179) were male. The median age was seven years (5 months–22 years). Patients served were from 17 of 28 districts within Malawi. Diagnoses of patients included 43% solid tumors (n=135), 22% lymphoma (n=68), 15% leukemia (n=47), and 21% hematologic disease (n=65). 40% of patients have died (n=125), with 53% of deaths occurring at home (n=66), 22% in the hospital (n=28), and 25% at unknown locations (n=31).
Palliative care is a critical component of PHO programs worldwide. Programs must leverage existing networks to ensure optimal care to children and families. We demonstrate the feasibility of integrating palliative care services within a PHO program in a low-resource setting, which could serve as a model for other countries in SSA.
Recent outbreaks of Chikungunya virus (CHIKV) infection confirm the vulnerability of neonates after vertical transmission. In 2014, CHIKV was reported for the first time in the Americas, including ...the island of Curaçao. We describe the outcomes of symptomatic neonates with vertically transmitted CHIKV infection during the CHIKV epidemic, who were admitted in the Saint Elisabeth Hospital, Willemstad, Curaçao. There were three symptomatic neonates with serologically confirmed infection. Two neonates developed neurological complications, including convulsions and intracerebral bleeding. One newborn, in whom maternal infection occurred 7 weeks before delivery, had a fatal outcome after birth. Maternal-fetal transmission of CHIKV may cause severe neonatal complications. There is a need to share experiences and to implement protocols toward the management of perinatal CHIKV infection.
The aim of this study was to determine the prevalence of 25-hydroxyvitamin D (25(OH)D) deficiency in a hospital-based population of both native Dutch and non-Western immigrants and to investigate the ...influence of immigrant status on the prevalence of vitamin D deficiency. A cross-sectional survey was conducted among 132 patients (1–18 years of age) visiting the paediatric outpatient department. Serum levels of 25(OH)D were measured using high-performance liquid chromatography. Cut-off levels of 30 and 50 nmol/l for serum 25(OH)D were evaluated. One third of the patients had serum 25(OH)D levels below 30 nmol/l, and half of the study population had serum levels below 50 nmol/l. Non-Western immigrants had an increased risk for vitamin D deficiency compared to their native Dutch peers 25(OH)D of <30 nmol/l,
p
= 0.03, odds ratio (OR) 3.87 (95 % confidence interval (CI) 1.13–13.29); 25(OH)D of <50 nmol/l,
p
= 0.02, OR 3.57 (95 % CI 1.26–10.14) with the highest risk for first-generation non-Western immigrants.
Conclusion
: Vitamin D deficiency in the paediatric population is still a matter of concern in the Netherlands, in particular among first-generation non-Western immigrants. We therefore strongly recommend vitamin D supplementation for all non-Western immigrants, regardless of age, skin type or season. Health-care staff who work with non-Western immigrants should be aware of the prevalence and implications of vitamin D deficiency.
