Development and validation of the Ibadan Simplified Developmental Screening chart

BACKGROUND

Developmental assessment remains an integral part of the routine evaluation of the wellbeing of every child. Children in resource-poor countries are not routinely assessed for signs of developmental delay and developmental disorders are frequently overlooked. A major gap exists in the availability of culturally appropriate and cost-effective developmental screening tools in many low and middle income countries (LMICs) with large populations.

OBJECTIVE

To bridge the existing gap, we describe the process of the development and validation of the Ibadan Simplified Developmental Screening (ISDS) chart, for routine developmental screening in Nigerian children.

METHODS

We developed an item pool across 4 domains of development namely, the gross motor, vision-fine motor, communication and socio-behavioural domains. The ISDS chart consists of 3-4 item questions for each domain of development, and responses are to be provided by the caregiver. Each chart is age-specific, from 6 weeks to 12 months. A total score derived from the summation of the scores in each domain are plotted on the ISDS scoring guide with a pass or fail score. Each child was evaluated by the Ages and Stages Questionnaire as the standard.

RESULTS

A total of 950 infants; 453 males and 497 females were enrolled. The estimates of internal consistency between the two instruments ranged between 0.7-1.0. Using the ASQ as the gold standard, the ISDS chart demonstrated a sensitivity of 98.8%, 78.4% and 99.7% in the gross motor, communication and the social and emotional domains respectively, for detecting infants who might require further assessment for developmental delays.

CONCLUSION

The indigenous tool fills a major gap in the need for cost-effective interventions for developmental monitoring in LMICs. Future work should include the deployment of the tool in the wider population, using digital health approaches that could underpin policy making in the region.

Early-onset developmental impairments among infants attending the routine immunization clinic at the University College Hospital, Ibadan, Nigeria

Developmental disorders are frequently overlooked in the developing countries, particularly in sub-Saharan Africa. Early identification of developmental delays (DDs) is critical to optimal outcomes. This study set out to determine the proportion of children who are at risk of DDs among infants attending immunization clinics at the University College Hospital, Ibadan, Nigeria. Infants 6 weeks to 12 months of age (median age 6 months) who presented for routine immunization were screened for DDs using the Ages and Stages Questionnaire. A total of 587 infants [312 (53.2%) males] were enrolled. A total of 198 (33.7%) children showed signs of DDs. For the domains of communication skills, fine motor skills, gross motor skills, problem solving/cognition skills and personal/social skills, the prevalences of DDs were 7.5%, 15.0%, 10.7%, 14.1% and 14.8%, respectively, and 14.3% had global DDs. Factors that significantly predicted DDs included prematurity (odds ratio [OR] 2.64 [95% confidence interval {CI} 1.45 to 2.05]) and a history of perinatal asphyxia (OR 1.74 [95% CI 1.77 to 2.49]). There is a need to incorporate routine developmental screening into the Nigerian healthcare system for timely recognition of DDs and prompt interventions.

Autistic disorder in Nigeria: profile and challenges to management

Autism represents one of the most common developmental disorders affecting children, but there are few reports on autism in African children. Our study describes the profile of autistic disorder in a cohort of Nigerian children and appraises short-term outcomes. Children seen at the pediatric neurology and the child psychiatry clinic of the University College Hospital, Nigeria were screened for autistic disorder using the American Psychiatric Association's Diagnostic and Statistical Manual IV. Forty-five males and 9 females were identified with autism, and the disease accounted for 2.3% of 2320 new cases seen during the period. The mean age at which parents observed deviations in behavior was 22.5 (SD=6.6) months, while the mean age at diagnosis was 44.7 (SD=21.2) months. Twelve (22.6%) children had a positive family history of autism, and forty (75.5%) had associated neurological comorbidities. Diagnosis of autism is often delayed in Nigeria, and affected children have a high frequency of neurological comorbidities.

Chronic blood transfusion for primary and secondary stroke prevention in Nigerian children with sickle cell disease: a 5-year appraisal

BACKGROUND

Chronic blood transfusion (CBT) diminishes the risk of primary and secondary stroke in sickle cell disease (SCD). We appraised CBT and assessed its feasibility as an option for stroke prevention in a setting of limited resources.

METHODS

All new cases of SCD seen in the Paediatric Hematology/Neurology units of the University College Hospital, Ibadan, Nigeria over a 5-year period were screened and followed up to identify those who had an indication for CBT for stroke prevention. Caregivers were counseled and offered CBT when indicated. Children of caregivers who accepted chronic transfusion were carefully followed up and outcomes documented.

RESULTS

Five (10%) of the caregivers of the 50 children who had an indication for CBT for stroke prevention consented to the treatment. They all had homozygous sickle cell anemia and had suffered a stroke. None of the children with abnormal TCD velocities consented to CBT. Two children experienced transfusion reactions, fatal in one. The mean annual cost of chronic transfusion (without chelation) was $3,276 (SD = 1,168). Major reasons given for declining CBT were high costs of blood transfusion, unavailability of blood, the need to regularly seek for blood donors, and the indefinite duration of blood transfusions.

CONCLUSION

High economic costs, unavailability of blood, need to regularly seek for blood donors, cultural beliefs, and high frequency of transfusion reactions are major challenges to a successful CBT program in Nigeria. There is a need for government subsidy on blood transfusions and improved efforts towards provision of safe and affordable blood.

Cost of epilepsy in children attending a tertiary centre in Nigeria

Epilepsy is one of the leading paediatric neurological disorders in Nigeria and many other parts of the world. There is very little documented on the economic costs of epilepsy in Nigeria and other countries in sub-Saharan Africa. This study was carried out to estimate the total cost of childhood epilepsy in a cohort of Nigerian children and therefore provide essential information on the economic burden of childhood epilepsy in Nigeria. A cost of illness study was performed on a cohort of 215 consecutive cases of epilepsy seen and treated at the University College Hospital, Ibadan, Nigeria. Data on demographics, clinical characteristics, utilization of resources and costs were collected. The total annual cost of epilepsy ranged from Nigerian naira (N)23 200 (US$155) to N3 298 500 (US$21,900) with a median of N107 600 (US$717) per patient per year. Direct medical and non-medical costs accounted for 71.8% of the total mean annual cost of epilepsy. Anti-epileptic drug therapy and in-patient care accounted for 21.8% and 33.0% of the mean total annual cost respectively and more than half of the families expended over 20% of their total family income on the care of the child with epilepsy. The economic burden of childhood epilepsy in Nigeria is enormous with very high out-of-pocket expenses.

Stroke recurrence in Nigerian children with sickle cell disease treated with hydroxyurea

AIMS AND OBJECTIVES

To compare the outcome after a first clinical stroke, following treatment with and without hydroxyurea (HU).

SUBJECTS AND METHODS

A retrospective review of a cohort of Nigerian children with SCD, who had suffered a first stroke, was carried out. Outcomes in the group of children who received and did not receive HU were compared.

RESULTS

Thirty two children presented with stroke and one died of haemorrhagic stroke at presentation. All the children had haemoglobin SS phenotype, and ischaemic stroke was the predominant form seen. Mean age at first clinical stroke was 7 years, 7 months (SD=2 years, 4 months). Thirteen children received HU while 18 declined HU therapy. Maximum dose of HU ranged from 20-25 mg/kg/ day. The secondary stroke incidence of 7/100 person years in the HU group was significantly lower than the 28/100 person years in the non-HU group (P=0.001, OR 3.808, 95% CI 1.556, 9.317). Children who did not receive HU were more likely to drop out of school and to have moderate-severe motor disabilities requiring caregiver assistance for daily living.

CONCLUSION

In settings where facilities for chronic blood transfusion are not accessible or feasible, HU therapy should be considered for secondary stroke prevention in children with SCD.

Complementary and alternative medicines use in children with epilepsy in Ibadan, Nigeria

BACKGROUND

There is documented evidence that the use of complementary and alternative medicines (CAM) has been on the increase worldwide.

METHODS

A standardized questionnaire was administered to caregivers of children with epilepsy to evaluate the prevalence and pattern of CAM use.

RESULTS

One hundred and seventy five caregivers of 175 children with epilepsy were studied. Ninety nine (56.6%) of the caregivers gave a history of CAM use. The forms of CAM used were herbal preparations (39.4%), spiritual/prayer healing (34.3%), scarifications (17.1%) and special vitamins (6.1%). Seventy (40%) of the 175 children had received CAM ever before seeking Western Medicine for the treatment of epilepsy. Of the 99 children with history of CAM use, 33 (33.3%) continued to use CAM in combination with the prescribed anti-epileptic drug (AED). Adverse effects were reported in 17 (17.1%) cases. There was no statistically significant relationship between the type of epilepsy and the use of CAM (p= 0.229, OR 1.655, 95% CI 0.608-4.508). There was a statistically significant inverse relationship between social class of the family (p = 0.043, OR 0.354, 95% CI 1.087-2.489) and mother's level of education (p = 0.013, OR 2.618, 95% CI 1.173-5.844) and the use of CAM. Only 30 (30.3%) of the 99 caregivers had spontaneously volunteered the history of the use of CAM to the attending physician and the leading reason for not giving the history was that the attending physician did not ask for the information.

CONCLUSION

Children with epilepsy frequently use CAM and attending physicians often fail to ask about use of CAM in the routine evaluation of patients. There is a need to routinely ask caregivers and patients about the use of CAM in management of their disease.

Adverse neurological outcomes in Nigerian children with sickle cell disease

Sickle cell disease (SCD) is reported to be the most common genetic disorder affecting Nigerians. Children with SCD are at a high risk of neurological morbidity. The main objective of this study was to determine the pattern of adverse neurological outcomes among a cohort of Nigerian children with SCD. All children with SCD seen in the Department of Paediatrics, University College Hospital, Ibadan, Nigeria, over a period of 2 years were carefully evaluated for symptoms and signs of neurological complications, defined as clinical outcomes referable to the central nervous system. Of the 214 children evaluated, 187 were diagnosed with Hb SS disease and 27 with Hb SC disease. Neurological complications were identified in 78 (36.4 %) of the cases. The most common complications were headache (17.8 %), seizure (9.3 %) and stroke (8.4 %). Other less frequent complications included bacterial meningitis (2.8 %), spontaneous visual loss (1.4 %), paraplegia (0.9 %) and transient ischaemic attacks (0.9 %). Neurological complications occurred more frequently in children with sickle cell anaemia than in those with Hb SC disease (P = 0.002, 95 % CI 1.450-82.870). Adverse neurological events are common in Nigerian children with SCD, with a significantly higher risk in Hb SS than Hb SC disease. Stroke represents a major underlying cause of symptomatic epilepsy in SCD. Institution of primary preventive measures for stroke in SCD will significantly reduce the burden of stroke and epilepsy associated with SCD in Nigeria.

Mental health problems in Nigerian children with epilepsy: associations and risk factors

Epilepsy is the most common neurological disorder affecting children, and the greatest burden of childhood epilepsy is found in the developing countries of the world. Behavioral problems are reported to occur more frequently in children with epilepsy, but there are limited studies on the pattern of behavioral problems in children living with epilepsy in sub-Saharan Africa. Eighty-four consecutive cases of epilepsy aged ≥5 years seen at the pediatric neurology clinic of the University College Hospital, Ibadan, Nigeria over a period of 9 months were screened for behavioral problems using the Rutter A2 scale. Behavioral problems were found in 39 (46.6%) of 84 subjects and occurred more frequently in males. Presence of associated learning difficulties (OR 5.13, 95% CI 1.61-16.36) and being diagnosed with epilepsy within 6 months of the onset of the first epileptic seizure (OR 4.54, 95% CI 0.073-0.69) independently predicted psychopathology in the cases studied. Emotional and behavioral problems are common in Nigerian children with epilepsy. There is a need for effective mental health services for children with epilepsy in order to optimize outcomes.

Predictors of early seizure remission in Nigerian children with newly diagnosed epilepsy

BACKGROUND

It is important to predict as soon as possible after diagnosis and starting treatment, the likely clinical course of childhood-onset epilepsy, both in terms of seizure control and even more pertinently, seizure intractability. Little is known about the factors predictive of seizure control in African children.

METHODS

All consecutive cases of newly-diagnosed childhood epilepsy seen over a period of two years in the Paediatric Neurology clinic, University College Hospital, Ibadan, Nigeria were prospectively followed for a period of three years to determine seizure outcomes. Remission was defined as being seizure-free for at least two consecutive years.

RESULTS

A total of 170 children were enrolled but 54 defaulted and were excluded from further analysis. Twenty nine (25%) attained remission while 20 (17.2%) showed signs of intractability. The remaining 67 (57.8%) showed some response to anti-epileptic drug (AED) therapy. Primary generalized epilepsy was found to be significantly associated with seizure remission and successful discontinuation of AED. Factors associated with reduced likelihood of seizure remission were remote symptomatic/cryptogenic aetiology, slow waves on electroencephalography (EEG), high seizure frequency of at least one attack/ month at presentation, failure of response to the initial AED and presence of associated neurological deficits. On logistic regression, high seizure frequency and presence of slow waves on EEG remained independent negative predictors of seizure remission.

CONCLUSION

About one-quarter of Nigerian children with newly diagnosed epilepsy attain early seizure remission within the first three years ofAED therapy. The major predictors of poor seizure control and failure of seizure remission include high seizure frequency at presentation and presence of slow waves on EEG.

Burden of health-care of carers of children with sickle cell disease in Nigeria

Sickle cell anaemia in children is characterised by recurrent crises that frequently involve intensive medical care which may impact on the health and well-being of their carers. The psychosocial impact of sickle cell disease on 67 carers of children with sickle cell disease attending the Paediatric Haematology/Oncology clinic of the University College Hospital, Ibadan, Nigeria, was determined between February and May 2007 using a structured questionnaire adapted from an instrument earlier validated for the study of carer burden in sickle cell disease and relevant to the Nigerian culture. Data analysis was performed using the Statistical Package for Social Sciences (SPSS) version 15.0. Demographic factors as well as frequency of hospitalisations and blood transfusions were each categorised into groups and the Mann-Whitney U-test was used to test for differences in stress scores between any two groups while the Kruskal-Wallis test was used to test for differences in more than two groups. Level of statistical significance was set at P < 0.05. Family finances were adversely affected in 39 (58.2%) families. Financial stress was frequently associated with a history of two or more hospitalisations in the previous year and more so in families with more than three children. Majority (80.6%) of the carers said they had minimal or no difficulty coping with their children. There was also a significant correlation between financial stress and difficulty in parental coping. Caring for the illnesses in the children often caused disruptions in family interactions; worst in the first year after diagnosis and improved over the years. Regular assessment of psychosocial areas of need is necessary to guide provision of necessary support.

Invasive pneumococcal disease in children aged <5 years admitted to 3 urban hospitals in Ibadan, Nigeria

BACKGROUND

Streptococcus pneumoniae remains a major cause of childhood morbidity and mortality in the world. The introduction of pneumococcal conjugate vaccine in developing countries will be facilitated by a clearer understanding of the disease burden for bacterial causes of pneumonia and meningitis and the prevalent serotypes of S. pneumoniae.

METHODS

We conducted a prospective, hospital-based surveillance for a 2-year period involving children aged 2-59 months at 3 urban hospitals in Ibadan, Nigeria, using standard microbiological methods with confirmation and further testing of isolates at the Medical Research Council Laboratories in The Gambia.

RESULTS

There were 1210 cases overall: 481 (39.8%) were meningitis, 399 (33.0%) were pneumonia, and 330 (27.2%) were bacteremia clinical syndromes. There were 24 cases of definite meningitis, of which 9 were caused by S. pneumoniae, 11 by Haemophilus influenzae type b, and 4 by Klebsiella species. Of the 90 culture-positive pneumonia cases, 9 were caused by S. pneumoniae, 2 by H. influenzae type b, and 79 by other species. Among cases of bacteremia, the pathogen isolation rate was 28.8% (95 of 330); the isolated species included S. pneumoniae (3 isolates), Staphylococcus aureus (20 isolates), Klebsiella species (13 isolates), Salmonella species (15 isolates), and Escherichia coli (6 isolates). Of the 23 S. pneumoniae isolates, 11 were serotyped; the serotypes found were 5 (5 isolates), 19F (3 isolates), and 4 (3 isolates), and 1 isolate was nontypeable. These isolates were all susceptible to penicillin. Eight of 9 patients with definite pneumococcal meningitis died, whereas all patients with pneumococcal pneumonia and septicemia survived.

CONCLUSIONS

Of the pneumococcal serotypes identified, 55% were covered by the licensed 7-valent pneumococcal conjugate vaccine, whereas all are covered by the 10- and 13-valent vaccines.

An analysis of disorders seen at the Paediatric Neurology Clinic, University College Hospital, Ibadan, Nigeria

BACKGROUND

Paediatric neurological disorders constitute a major cause of disability in childhood. Children in the developing countries are disproportionately affected and in addition face the added burden of poverty, inadequate health facilities, stigmatisation and lack of facilities for rehabilitative care.

OBJECTIVE

To describe the spectrum of neurological disorders seen among Nigerian children presenting at the paediatric neurology clinic of the University College Hospital, Ibadan, Nigeria.

METHODS

All children presenting at the paediatric neurology clinic of the University College Hospital, Ibadan, Nigeria over a period of 20 months were prospectively studied. Diagnoses were made from detailed history, thorough physical examination, with particular emphasis on the central nervous system and appropriate investigations as indicated.

RESULTS

There were a total of 644 cases during the study period, 369 males and 275 females, giving a male to female ratio of 1.3:1. There were 1353 consultations at the paediatric neurology clinic and these accounted for 21.0% of the total 6,442 consultations at the paediatric specialist clinics in the hospital. The most frequent paediatric neurological disorders were epilepsy (45.3%), cerebral palsy (36.0%), neuro-muscular disorders (4.5%) and mental retardation (4.5%).

CONCLUSION

Paediatric neurological disorders constitute a major reason for paediatric specialist care in Ibadan, Nigeria. Preventable causes play a major role in the aetiology of the major paediatric neurological disorders seen in this part of the world.

Childhood bacterial meningitis in Ibadan, Nigeria--antibiotic sensitivity pattern of pathogens, prognostic indices and outcome

Bacterial meningitis remains a major cause of morbidity, mortality and neurodisability in childhood, particularly in the developing world where effective vaccines against the usual pathogens responsible for the disease are not in routine use. To describe the patterns and outcome of bacterial meningitis among children admitted into the University College Hospital (UCH), Ibadan, Nigeria. All children who satisfied the case definition for meningitis, admitted into the paediatric wards of the University College Hospital, UCH, Ibadan over a period of 30 months were prospectively enrolled and blood and CSF samples were taken for bacteriological analyses. A total of 97 children, 62 males and 35 females were studied. Their ages ranged between 2 months and 12 years, mean age 33.0 (SD=41.7) months, with 80.4% of the cases below the age of 5 years. Haemophilus influenzae type b (Hib) was the leading pathogen, found in 16 (55.1%) of the 29 cases of definite meningitis. Other isolates include Streptococcus pneumoniae (24.1%), Klebsiella spp (7.0%), Staphylococcus aureus (7.0%), Escherichia coli (3.4%) and Pseudomonas spp. (3.4%). Hib and pneumococcus showed varying degrees of resistance to chloramphenicol, penicillin and cotrimoxazole. Twenty six (26.8%) of the cases died and 67.6% of the survivors developed significant neurological sequele. Bacterial meningitis remains a major cause of childhood mortality and neurodisability. Hib and pneumococcus remain the major pathogens responsible for this dreadful disease in Ibadan, Nigeria. The increasing emergence of antibiotic resistance calls for institution of adequate control measures, particularly routine childhood immunisation against the disease.

Holoprosencephaly in Ibadan, Nigeria: a report of three cases and review of literature

Holoprosencephaly is a rare congenital malformation resulting from failure of cleavage of midline structures of the forebrain and face. It affects 0.49-1.2 in 10,000 births around the world. The nature of this condition in African children is not well documented in literature. We present a cluster of three cases of holoprosencephaly with varying degrees of facial and intracranial malformations seen within a 6 month period at the University College Hospital, Ibadan, Nigeria.

Ocular abnormalities in children with cerebral palsy

This prospective study was undertaken to evaluate the prevalence of ocular abnormalities, as well as describe the various eye defects seen among cases of cerebral palsy presenting at the Paediatric Neurology Clinic, University College Hospital, Ibadan, Nigeria. All cases of cerebral palsy seen at the Paediatric Neurology Clinic, University College Hospital, Ibadan, over a period of 18 months were carefully evaluated by the Paediatric Neurologist for signs of ocular abnormalities. Those in whom such abnormalities were found were referred to the Consultant Ophthalmologist for detailed eye examination and accurate description of the ocular abnormalities. One hundred and forty nine children with cerebral palsy were seen during the period of study, forty two had associated ocular abnormalities, giving a prevalence rate of 28.2%. More than half (61.9%) of the cases were completely blind. The major ocular abnormalities identified in the affected cases were strabismus (50%), optic atrophy (50%) and cortical visual impairment (47.7%). Other eye defects less frequently seen were nystagmus (9.5%) and refractive errors (4.8%). Presence of spastic quadriplegia was associated with an increased risk of ocular abnormalities. Ocular abnormalities are a frequent problem in children with cerebral palsy. Evaluation of all children with cerebral palsy must include amongst other things, a full ophthalmologic evaluation, even when no gross eye anomalies are visible to the attending physician. Early identification of these defects in children with CP is crucial in order to institute prompt therapy in cases with defects that are amenable to treatment.

Non-traumatic paraplegia in Nigerian children presenting at the University College Hospital, Ibadan

A review of the presentation, management and outcome in all children presenting with non-traumatic paraplegia managed by the paediatric neurology team at the University College Hospital Ibadan, Nigeria from June 1989 to May 2004 is presented. Of the 110 patients, there were 54 males and 56 females giving a M:F ratio of 1:1. The mean age of the group was 5.3 (SD = 3.1) years, with a range from 9 months to 11 years. Infections and infectious processes caused the paraplegia in 102 (92.7%) of the cases with poliomyelitis and tuberculosis (TB) of the spine accounting for 88 (80%) of cases. The study period was divided into three 5 year periods. While poliomyelitis was the commonest cause of paraplegia (60%) in the first 5 years: TB spine was responsible for most cases (40%) in the last 5-year period of the study. There was a significant reduction in the total number of cases seen when the initial 5-year period was compared with the last (45 and 26 respectively, P = 0.001). Overall mortality among the 110 admitted patients was 7.2% being highest (50%) in malignant disorders and none was recorded in TB spine. Prognosis for eventual ability to walk was best in cases of TB spine where 37 of the 39 patients (95%) were ambulant by discharge after 60 days of anti-TB treatment. The 2 non-ambulant patients eventually walked within 3 months of discharge while on maintenance treatment for TB. Only 2 of the 51 non-ambulant patients obtained wheelchairs at discharge. The implications of inadequate facilities for investigation and treatment as well as the lack of financial and social support for the families of affected children are discussed.

Intrauterine fetal death of one of twins, coexisting with hydranencephaly in the surviving co-twin: a case report

Hydranencephaly, a relatively rare malformation of the brain, is characterised by absence of the cerebral hemispheres and their replacement by sacs filled with cerebrospinal fluid. It is one of the recognised forms of intracranial malformations associated with intrauterine fetal demise of one of twins in monochorionic twin gestation. This report illustrates the development of hydranencephaly in a surviving twin sequel to intrauterine fetal demise of the co-twin.

Measles in Ibadan: a continuous scourge

Measles remains one of the leading causes of childhood mortality in the world, despite the availability of a safe, effective, relatively inexpensive vaccine. It is also one of the leading causes of childhood blindness in the developing world. We reviewed the records of cases of measles admitted into Oni Memorial Children's Hospital, Ibadan over a 5-year period, January 2000 to December 2004; to evaluate any changes in the pattern of the disease. A total of 666 cases of measles were admitted comprising of 347 males and 319 females, giving a male to female ratio of 1.1:1. The yearly incidence of measles remained fairly the same from January 2000 to December 2002. There was a marked increase in yearly incidence in the year 2003. The majority of the affected children (74.1%) were 2 years and below. One hundred and thirty-six (20.4%) cases developed measles before the age of 9 months, the recommended age for measles vaccination in Nigeria. The peak incidence occurred in the months February and March. The commonest complication was bronchopneumonia, seen in 45.2% of cases. Other complications include protein-energy malnutrition, tuberculosis, croup, keratopathy, otitis media, heart failure and tension pneumothorax. Fifty-six patients died giving a case fatality rate of 8.4%. Factors associated with increased mortality were young age (<2years) and malnutrition. Measles remains a major threat to the health of the Nigerian child. A significant number of children developed measles before receiving the required vaccination at the recommended age of 9 months. There is a need to review the current immunisation policy, strengthen immunisation practices and improve the living standards in order to make the eradication of measles a reality.

Prognostic indices in childhood heart failure

OBJECTIVES

To evaluate the short term prognosis of childhood heart failure and highlight the factors that affect outcome among cases of heart failure admitted into the paediatric wards, University College Hospital, Ibadan.

BACKGROUND

Childhood heart failure remains a major cause of morbidity and mortality in the developing world. The advent of open heart surgery, use of better myocardial preservative techniques, and the introduction of newer, more effective drugs in the treatment of heart failure have greatly improved the outcome of children with heart failure in the developed world. The outlook of such children in the developing world however remains poor.

METHODS

One hundred consecutive cases of heart failure admitted into the Paediatric wards of the University College Hospital, Ibadan with a diagnosis of heart failure over a 10-month period were studied prospectively. Diagnosis of heart failure was based on the presence of at least three of the four cardinal signs of heart failure: tachypnoea, tachycardia, tender hepatomegaly and cardiomegaly. All cases were followed up daily till a definite outcome was determined.

RESULTS

The predominant underlying causes of heart failure were acute respiratory infections (36%), severe anaemia (28%), and congenital heart disease (25%). There was a case-fatality rate of 24% among the study population. Poor prognostic indices identified were age below one year or above 5 years, presence of underlying acute respiratory infections, rheumatic heart disease and renal disorders.

CONCLUSION

Heart failure in Nigerian children though mostly due to preventable causes, are associated with an unacceptably high mortality.

Childhood heart failure in Ibadan

One hundred consecutive admissions of children with a diagnosis of congestive cardiac failure to the paediatric department of the University College Hospital, Ibadan were evaluated during a 10-month period. They were aged 8 days to 12 years. They constituted 5.8% of the total paediatric admissions during the study period. The most frequent underlying causes of heart failure were acute lower respiratory tract infections (36%), intrinsic heart disease (31%) and severe anaemia (28%). Other less common causes of heart failure were renal disorders (3%) and septiceamia (2%). Heart failure remains a common problem encountered in emergency paediatric practice in Nigeria, with the majority of cases resulting from preventable causes.
