RESUMO

INTRODUCTION: The InPOG-HL-15-01, a multicentric prospective study, used a risk-stratified and response-based approach with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) backbone to treat children and adolescents with newly diagnosed Hodgkin lymphoma (HL) and reduce the use of radiation therapy (RT). Children/adolescents with bulky disease or inadequate response at early response assessment (ERA) after two cycles of chemotherapy were assigned to receive RT. For ERA, positron emission tomography computed tomography (PET-CT) was recommended but not mandatory in view of limited access. This study aimed to compare the impact of using contrast-enhanced computed tomography (CECT) and PET-CT on treatment decisions and outcomes. METHODOLOGY: 396 patients were enrolled and 382 had an ERA at the assigned time point. Satisfactory response was defined as Deauville score 3 or less for patients undergoing PET-CT and complete response (CR)/very good partial response (VGPR) for patients undergoing CECT. Outcomes of interest incorporate 5 year event-free survival (EFS), EFS including abandonment (EFSa), and overall survival (OS). RESULTS: At ERA, satisfactory response was documented in 277 out of 382 (72.5%) participants and this was significantly higher in PET-CT (151 out of 186, 81.2%) as compared with CECT-based assessments (126 out of 196, 64.3%) respectively (p value < .001). Amongst the 203 patients with nonbulky disease (wherein the indication for RT was entirely dependent on ERA), 96 out of 114 (84.2%) and 61 out of 89 (68.5%) patients achieved a satisfactory response according to the PET-CT and CECT (p value = .008) respectively and hence a lesser proportion of patients in the PET-CT arm received RT. Despite a lower usage of RT the 5 year OS of both groups, ERA based on CECT (91.8%) versus PET-CT (94.1%) was comparable (p value = .391) and so was the 5 year EFS (86.7 vs. 85.5%, p value = .724). CONCLUSION: Use of PET-CT as the modality for ERA is more likely to indicate a satisfactory response as compared with CECT and thereby decreases the need for RT in response-based treatment algorithm for HL-afflicted children. The reduction in the application of RT did not impact the overall outcome and plausibly would lower the risk of delayed toxic effects.

RESUMO

OBJECTIVES: The objectives of this study were to study the spectrum of neurologic complications in children with lymphoreticular malignancy (acute lymphoblastic leukemia, Hodgkin, and non-Hodgkin lymphoma) at diagnosis and during treatment and to determine the etiology of these complications. MATERIALS AND METHODS: In this descriptive cohort study, conducted between November 2018 and March 2020, 204 children with a diagnosis of lymphoreticular malignancy were enrolled. The baseline investigations were done in all the cases. Those who developed neurological symptoms were evaluated with cerebrospinal fluid examination and radiologic and electrophysiologic studies as per indication and were managed according to standard management guidelines. RESULTS: Of the 204 patients, 30 (14.7%) developed neurological complications. The majority of these complications (n=20/30; 87%) occurred during the intensive chemotherapy period. Common complications included acute methotrexate neurotoxicity (n=7), vincristine-induced neurotoxicity (n=7), central nervous system (CNS) relapse (n=4), and posterior reversible encephalopathy syndrome (n=2). L-asparaginase-induced thrombosis (n=1), intramedullary compression syndrome (n=1), CNS infection (n=2), CNS hemophagocytic lymphohistiocytosis (n=1), and steroid-induced myopathy (n=1) were also observed. The complications resolved in 21/30 (70%) patients after receiving appropriate treatment while the neurological complication persisted in 2/30 (6.7%) patients. Three patients (10%) abandoned the treatment, and 4 (13.3%) patients expired. CONCLUSIONS: Neurologic complications in patients with lymphoreticular malignancy are quite variable, having common presenting symptoms but varying imaging abnormalities. By close follow-up and effective treatment, the morbidity and mortality of these complications can be minimized.

RESUMO

The median age of presentation for Hodgkin lymphoma (HL) is lower in developing countries with a higher proportion under 5 years of age possibly attributable to the high prevalence of Epstein-Barr virus-driven disease. It is unclear whether the clinical presentation and outcomes of this cohort are different with concern regarding late effects being most pronounced in this age group. We report the outcome of children under 5 years of age enrolled in the InPOG-HL-15-01, the first multicentric collaborative study for newly diagnosed children and adolescents with HL from India. Thirty-five (9%) of the study population was younger than 5 years with a striking male preponderance of 34:1. They were less likely to have bulky disease, mediastinal or splenic involvement. The outcomes appear to be at least as favorable as in the older patient group. Efforts need to be made to evolve treatment strategies that spare this very young cohort from potential late effects.

RESUMO

AIM: COVID-19 has presented an unprecedented challenge to health services and has significantly affected the management of non-Covid illnesses, like thalassemia. The present study documents the impact of Covid-associated restrictions and disruptions on working of the pediatric thalassemia day care centre (TDCC), and measures taken by TDCC and blood transfusion services to adapt to and mitigate the negative impact of Covid pandemic and associated lockdown on patient care. METHODS: Pre-transfusion haemoglobin and packed cell transfusion requirement were compared across three time periods, namely pre-lockdown, lockdown and post-lockdown in paediatric transfusion-dependent thalassaemia (TDT) patients. Caregivers were interviewed to document any problems faced by them. RESULTS: The study involved 181 TDT patients. There was a significant reduction in mean pre-transfusion haemoglobin and red cells transfused during lockdown phase as compared to pre-lockdown phase. Regular care was interrupted in 45% of patients and 76% of patients getting blood from outside could not get leukoreduced red cells. Investigations, monitoring and continuity of iron chelation were also affected. Blood centre faced 30.5% reduction in blood supply during lockdown. TDCC and blood centre took several steps, including prolongation of service hours and staggering of transfusions to ensure maximum transfusions while ensuring social distancing. CONCLUSION: The COVID-19 pandemic imposed many unprecedented challenges to the routine care of thalassaemic patients; however, some of them could be dealt with by a proactive approach and micro-planning at the institution level. Other similar resource-limited settings could learn from experiences for continued quality care for chronic medical conditions during pandemic like situations.

RESUMO

BACKGROUND: Hodgkin lymphoma (HL) in childhood is an eminently curable disease. Excellent outcomes can be achieved even in resource-limited settings and increasingly, the focus is on limiting long-term toxicity. Contemporary treatment incorporates a risk-stratified, response-adapted approach using multiagent chemotherapy with or without low-dose radiotherapy (RT). Many developing countries continue to use ABVD (adriamycin, bleomycin, vinblastin, and dacarbazine)-based regimen owing to limited acute toxicity, cost, and ease of delivery. We report outcomes of children with early-stage HL using limited cycles of ABVD-based treatment in the first prospective multicentric collaborative study from India InPOG-HL-15-01. METHODS: Children <18 years with biopsy-proven HL were enrolled. Patients with stages I and IIA with or without bulky disease were classified as having early-stage disease. Patients were planned to receive four cycles of ABVD subject to satisfactory early response assessment (ERA) scheduled after two cycles of chemotherapy. RT was limited to patients with bulky disease or those with suboptimal ERA. RESULTS: Four hundred ten patients were enrolled over 30 months from 27 centers. One hundred thirty-four were classified as having early-stage disease. Fifty-three (40%) of these had bulky disease. One hundred ten (83%) of this cohort achieved complete or very good partial ERA. Fifty-four (40%) received RT. At a median of 52 months since diagnosis, 5-year event-free survival (EFS) and overall survival (OS) is 94% and 95.5%, respectively. Treatment-related mortality and abandonment were <1%. CONCLUSION: Limited cycles of ABVD with RT to selected patients is a very effective option for patients with early-stage disease in resource-limited settings.

RESUMO

BACKGROUND: Febrile neutropenia (FN) is a common life-threatening complication in patients with severe aplastic anemia (SAA). However, few studies have examined the spectrum of infections in FN in patients with SAA, especially in children. Therefore, the current study was planned to study the clinicomicrobiologic profile of FN episodes in these children. MATERIALS AND METHODS: Data of 38 episodes of FN that occurred in 31 children with SAA from November 2015 to April 2017 were collected prospectively and analyzed. RESULTS: FN episodes occurred more frequently (54.8%) in patients on immunosuppressive therapy. Clinically documented infections accounted for 21 (55.26%) episodes, microbiologically documented infections for 15 (39.47%), bacteremia for 13 (34.21%), and invasive fungal diseases for 6 (15.78%) episodes. Among clinically documented infections, the lower respiratory tract was the commonest site in 23.68% episodes, followed by skin and soft tissue infections. No focus of infection could be identified in 12 (31.57%) episodes. Gram-negative bacteria (71.42%) were the predominant isolates (commonest Klebsiella pneumoniae) over Gram-positive bacteria (commonest coagulase-negative Staphylococcus). High prevalence of aminoglycoside, piperacillin-tazobactam, and carbapenem resistance was noted among Gram-negative organisms. Gram-positive organisms showed excellent sensitivity to vancomycin, linezolid, and clindamycin. The overall mortality rate was 42%. CONCLUSIONS: Empirical antimicrobial therapy should include adequate coverage for Gram-negative pathogens. The antimicrobial regimen should be modified according to the results of the culture and sensitivity testing.

RESUMO

BACKGROUND: Arthropathies and bone deformities are well known to occur in patients with thalassemia major and have been attributed to the disease or to its therapy. Before the advent of chelation therapy, these children developed widened diploic space and "hair-on-end" pattern in skull, "cobweb" pattern in the pelvis, and the lack of the normal concave outline in the long bones because of extensive marrow proliferation. After the introduction of iron-chelation therapy, these patients were noted to develop metaphyseal abnormalities and vertebral changes resembling spondylo-metaphyseal dysplasia. Only one study has shown some association of deferiprone (chelating agent) use with distal ulnar changes in these children. Our study was done to describe the skeletal changes and deformities in wrist joints of children with transfusion-dependent thalassemia and correlate them with age, mean pretransfusion hemoglobin level, mean serum ferritin level, and type and duration of chelation therapy in these children. METHODS: A total of 60 children with transfusion-dependent thalassemia from the thalassemia daycare center were examined. These children were divided into 3 groups on the basis of their age (group A: 2 to 6 y, group B: 6 to 10 y, and group C: 10 to 14 y). Detailed history, including treatment history, number of blood transfusions received over the last 1 year, clinical examination, and radiologic assessment of both forearm with wrists were done. RESULTS: The clinical and radiologic differences in radial and ulnar lengths increased significantly with the increasing age of these patients, the ulna being short. There was some correlation between increasing negative ulnar variance and distal radial articular angle with deferiprone consumption. CONCLUSION: Chelation therapy, particularly with deferiprone, may cause distal ulnar growth arrest causing ulnar shortening and progressive radial bowing in these children. LEVEL OF EVIDENCE: Level IV-case series.

RESUMO

The WHO Integrated Management of Childhood Illnesses-HIV (IMCI-HIV) algorithm and its regional adaptation have shown variable performance in clinically identifying HIV-infected children with lack of validation in low prevalence areas. Addition of certain 'parental factors' (proxy indicators of parental HIV) may improve its utility. In this study, children aged 2 months to 5 years were enrolled into Group A (n = 1000, 'suspected symptomatic HIV infected' children as per the IMNCI-HIV algorithm) and group B (n = 50, children newly diagnosed with HIV infection). Parental factors were asked and HIV infection was tested for in Group A. For Group B, retrospective data were collected regarding IMNCI-HIV algorithm signs and parental factors. Utility of individual and various combinations of IMNCI-HIV signs and parental factors to predict HIV status was evaluated. Results showed that incorporating parental factors to IMNCI-HIV algorithm improved its sensitivity and positive predictive value in identifying HIV-infected children while maintaining the same sensitivity.

RESUMO

Injection vincristine is an important component of therapy for acute lymphoblastic leukemia (ALL). An important adverse effect of vincristine is neurotoxicity. The incidence of this adverse effect is well studied. The present was undertaken to determine the incidence of vincristine-induced neurotoxicity in children with ALL after the induction of remission phase of chemotherapy and to ascertain its correlation with undernutrition, vitamin B12, folate and iron deficiency. Thirty children (1-18 years) with ALL were enrolled at the commencement of chemotherapy. The electrophysiological evaluation was done at baseline and repeated after four doses of vincristine (1.5 mg/m2/dose). Clinical evaluation was done regularly. Anthropometry and serum B12, folate and ferritin levels were assessed at baseline. Twelve children over a 4-week period of observation had peripheral neuropathy clinically. The autonomic system was most commonly involved followed by motor and sensory system respectively. On electrophysiological testing, half of the patients had evidence of neuropathy. Micronutrient deficiencies were present in a significant number of patients-63.3% had a B12 deficiency, 20% were deficient in folate and 43.3% in iron. The incidence of vincristine-induced neuropathy in patients with/without these micro-nutrient deficiencies was not statistically significantly different. Vincristine-induced neuropathy is common in Indian children with ALL. The present study did not find any correlation between the occurrences of vincristine-induced neuropathy and nutritional deficiencies. Larger studies are warranted to evaluate the contribution of micronutrient deficiencies to the development of peripheral neuropathy in childhood ALL.

RESUMO

BackgroundBacterial infections account for a significant proportion of neonatal and infant mortality globally. We aimed to identify predictors of death in infants with probable serious bacterial infection (PSBI) defined as signs/symptoms of possible serious bacterial infection along with baseline C-reactive protein (CRP) ≥12 mg/l.MethodsWe did a secondary analysis using the data collected from 700 infants with PSBI who participated in a randomized controlled trial in India in which zinc or placebo was given in addition to the standard antibiotics. Logistic regression was used to estimate the associations between relevant variables and death within 21 days.ResultsThose infants who were fed cow's milk or formula before the illness episode had 3.7-fold (95% confidence interval (CI) 1.5-9.3) and 5.3-fold (95% CI 2.0-13.6) higher odds of death, respectively. Lethargy (odds ratio (OR) 2.4, 95% CI 1.1-5.4) and CRP (OR 1.9, 95% CI 1.1-3.3) were also independent predictors of death. In the model including only clinical features, female gender (OR 2.25, 95% CI 1.0-5.0), abdominal distention (3.7, 95% CI 1.1-12.3), and bulging fontanelle (5.8, 95% CI 1.1-30.5) were also independent predictors for death.ConclusionFormula or cow milk feeding prior to the illness, lethargy at the time of presentation, and high serum CRP levels predicted death in infants with PSBI.

RESUMO

Objective: To evaluate the effect of zinc as an adjuvant therapy in radiologically confirmed pneumonia in children 2-24 months of age. Patients and Methods: We analyzed data of 212 children with pneumonia for whom chest X-ray films were available at enrollment and at least two radiologists agreed on the diagnosis of pneumonia. We compared the time to recovery in the two groups (n = 121, zinc group and n = 91, placebo group) using a Cox proportional hazards regression model. Results: Time to recovery was similar in both groups [median interquartile range: zinc, 84 h (64, 140 h); placebo, 85 h (65, 140 h)]. The absolute risk reduction for treatment failure was 5.2% (95% confidence interval: -4.8, 15.1) with zinc supplementation. Conclusion: There was no significant beneficial effect of zinc on the duration of recovery or risk of treatment failure in children with radiologically confirmed pneumonia.

RESUMO

To demonstrate the efficacy of oral methylcobalamin in treating vitamin B12 (vitB12) deficiency anemia, our prospective observational study enrolled 28 children with both macrocytic anemia and low holotranscobalamin (HoloTC) levels. Their hematological and biochemical parameters pre- and posttreatment at 1 month were compared. Hemoglobin showed mean increase of 2.89 g/dl (P < 0.001), rising above 10 g/dl in 24 patients (85.7%). Reticulocytes peaked at 1 week. Mean fall in mean corpuscular volume of 24.83 fl (P < 0.001) and mean improvement in platelets of 122,100/µl (P = 0.001) were noted, and mean rise in HoloTC and vitB12 were 111.36 pmol/l (P < 0.001) and 918.34 pg/ml (P < 0.001), respectively. Thus, initial responses to oral methylcobalamin in children with vitB12 deficiency anemia were adequate.

RESUMO

HIV exposed children are vulnerable to developmental delay irrespective of their HIV status due to combined effect of risk factors like poverty, prenatal drug exposure, stress and chronic illness in family and malnutrition. This cohort study assessed the development of 50 HIV exposed children aged 6-18 months at a Pediatric Centre of Excellence in HIV care in India. The development was assessed using Development Assessment Scale for Indian Infants (DASII) at enrolment, 3 and 6 months later. The development quotient (DQ) scores and proportion of children with developmental delay (DQ ≤ 70) were compared among two sub-groups, HIV infected (HI) and HIV exposed uninfected (HEU) children. The various social and clinical factors affecting development were studied by univariate and multivariate analysis. Prevalence of developmental delay was 2.4% in the HEU (n = 41), and 33.3% in HI (n = 9). The DQ of HI was significantly lower than that of HEU at all three assessments. The DQ of HI were also significantly lower compared to the HEU at ages 12.1-18 months (83.37 ± 20.73 vs 94.68 ± 5.13, p = 0.005) and 18.1-24 months (84.55 ± 15.35 vs 94.63 ± 5.86, p = 0.006) respectively. The development of HEU was adversely affected by lower socioeconomic status and presence of wasting. In addition, development of HI was also adversely influenced by presence of stunting and opportunistic infections, advanced disease stage and shorter ART duration. We conclude that with optimum care, HEU can have a normal development, while a considerable proportion of HI may continue to have delayed development.

RESUMO

OBJECTIVE: A combination of desferrioxamine with either deferiprone (DFP) or deferasirox (DFX) for patients with ß-thalassemia major who do not achieve negative iron balance with monotherapy has been studied widely. However, poor compliance resulting from the need for parentral administration of desferrioxamine and its cost necessicitates combining 2 oral chelators. METHODS: A prospective study was conducted in patients with transfusion-dependent ß-thalassemia major in a tertiary care center over 2 years. Patients on either DFP or DFX who were not improving on monotherapy over a long period and persistently maintaining serum ferritin >2500 µg/L were enrolled. Efficacy was assessed by serum ferritin levels assessed at 12 months and 2 years. Complete blood counts and liver and kidney function tests were monitored to assess the safety of the combination of drugs. RESULTS: In total, 33 patients with a mean age of 12.67 years (7.5 to 17.5 y) and a mean ferritin of 4835.2394±1443.85 µg/L formed the study cohort.In total, 28 patients completed the 1-year study period; and 12 patients completed 2 years. Mean serum ferritin reduction at 1 and 2 years was 34.99%±18.13% (range, -34.36% to 56.17%) and 44.67%±13.78% (range, 22.17% to 62.74%), respectively. The combination therapy was well tolerated. CONCLUSIONS: Combined oral chelation with DFP and DFX has better efficacy than either drug used alone. The combination of drugs was well tolerated and no new adverse effects were observed.

RESUMO

BACKGROUND & OBJECTIVES: Measles infection is reported to be more severe, prolonged and associated with a higher complication rate in children with HIV infection. Reports indicate that infants born to HIV-infected women [HIV exposed infants (HEI)] may be more vulnerable to measles. The World Health Organization recommends measles vaccination starting at six months of age in these infants who may be HIV-infected themselves. However, in India, they are given measles vaccination at nine months of age like all other infants. In this study, the seroprevalence of transplacentally acquired measles antibodies was compared in HEI and unexposed infants (HUnI) at six months of age and the proportion of HEI undergoing seroconversion after immunization with measles vaccine was assessed. METHODS: In this prospective longitudinal study, measles IgG antibodies were estimated in serum of 49 HEI and 50 HUnI aged 6-7 months. Measles vaccine was then administered to HEI. Assessment for measles IgG antibodies was repeated 8-12 wk post-immunization. RESULTS: Measles IgG antibodies were detected in two of 49 (4.1%) HEI and 16 of 50 (32%) HUnI. HEI were 11 times more likely to lack measles antibodies as compared to HUnI (odds ratio=11.05, 95% confidence interval=2.989-40.908). Post-vaccination, seroprevalence of measles antibodies increased to 38.5 per cent (PInterpretation & conclusions: Most HEI lacked measles antibodies at six months age and were, therefore, more vulnerable to measles than HUnI. Seroconversion in response to a single dose of measles vaccine administered at six months age was low in these infants, signifying the need of additional dose(s) of measles/measles-containing vaccine.

RESUMO

Transfusion-dependent thalassemia (TDT) and its treatment affect the physical, emotional, and social functioning, impairing the quality of life (QoL). There are few studies on QoL of adolescent with TDT. Its effect on their siblings' QoL has not been studied so far. In this cross-sectional study, 40 adolescents with TDT, 28 siblings, and 40 controls were studied to assess the QoL of adolescents thalassemics, and their siblings using the shorter version of World Health Organization Quality of Life instrument, the WHOQOL-BREF. Thalassemics had poor perception of their general health and scored significantly lower in all the subscales compared with the controls. Lowest mean subscale scores were for physical (57.7 vs. 72.4, P<0.001), and psychological domains (56.7 vs. 72.3, P<0.001). Their siblings also scored significantly less in environment domain. Prevalence of school dropout, short stature, and delayed puberty were significantly higher in thalassemics. Pretransfusion hemoglobin, age at onset of anemia, and chronological age were found to be significant predictors of total summary scores. This study showed that the concept of QoL is a cumulative reflection of individual and disease variables and highlights the negative impact of thalassemia on the patients' QoL and some aspects of their siblings' lives also.

RESUMO

The oral iron chelator deferiprone is associated with various side effects including agranulocytosis, arthropathy, and deranged liver function tests. Rarely, neurological and visual side effects have been reported with high doses. The authors describe rare neurological manifestations of cerebellar ataxia, hypertonia, and bilateral cataract in an 11-year-old boy with thalassemia major on recommended therapeutic doses of deferiprone. The neurological abnormalities resolved with stoppage of deferiprone. Central nervous system toxicity and lenticular opacities may be attributed to the low molecular weight of deferiprone and its ability to cross the blood-brain and blood-ocular barrier, respectively. Clinicians should be alert to the possibility of neurological abnormalities that may occur during deferiprone therapy.

RESUMO

The objective of this study is to assess adherence to antiretroviral therapy (ART) in HIV-infected children using the pill count method, and determine factors leading to adherence failure. Records of 106 children living with HIV (CLHIV) age <15 years and on ART for >6 months were reviewed. Average adherence to ART by pill count method over preceding six months was calculated and re-assessed by 3-day recall method. The caregivers of 105 children and one child himself were interviewed about the problems encountered while giving ART. Median age of enrolled children was 104 (inter-quartile range [IQR] 77.3-133.8) months. Median duration of ART was 25 (IQR 16-35) months. The desired adherence level of >95% during six months of review assessed by pill count was achieved in 95.3% children. The 3-day recall method yielded >95% adherence in 99% children (p ≤ .001). Caregivers of 59 children (56.2%) reported multiple problems while administering drugs. In most instances, problems encountered were related to family/caregivers, the commonest being multiple caregivers, job constraints and death/illness in the family. In conclusion, we found a very high level of adherence to ART in CLHIV. Poor adherence was mainly associated with issues related to the family/caregivers.

RESUMO

Inflammatory myofibroblastic tumors are rare lesions of uncertain etiology that are often difficult to diagnose because of their myriad clinical presentations. Not uncommon, they mimic persistent pneumonia. We report a 4-year-old girl who presented with prolonged pyrexia, weight loss, severe anemia, hepatosplenomegaly, and nonresolving pneumonia. Initial investigations including flexible bronchoscopy and bronchial washing for usual causes of persistent pneumonia, such as tuberculosis and other infections, were negative. Chest computed tomography revealed a well-defined lesion involving the lingula and left upper lobe with extension into the subpleural space. Pleural tap and biopsy was also noncontributory. Thoracoscopic biopsy was suggestive of an inflammatory myofibroblastic tumor. As the lesion was encasing the major vessels, it was considered inoperable. The patient did not respond to steroid therapy and etoricoxib and later succumbed to the illness. This uncommon tumor should be considered in the differential diagnosis of children who presented with unresolving consolidation with pyrexia.
