Insights

Sickle cell disease (SCD) complications cause child mortality in Africa. Key risk factors for death in children with SCD include lack of follow-up care and low hemoglobin levels, highlighting access to care issues.

Area of Science:

  • Pediatric Hematology
  • Global Child Health

Background:

  • Sickle cell disease (SCD) is a major cause of mortality in children, particularly in Africa and India.
  • Research on prognostic factors for adverse SCD outcomes in African children is limited.

Purpose of the Study:

  • To identify prognostic factors associated with mortality in children and adolescents under 15 with sickle cell disease.

Main Methods:

  • Retrospective study of pediatric patients diagnosed with sickle cell disease.
  • Data collected included clinical and laboratory parameters at admission.
  • Univariable and multivariable analyses were used to assess the association between variables and mortality.

Main Results:

  • The overall mortality rate was 12.9% (64 deaths).
  • Bacterial infections accounted for 40.1% of deaths.
  • Independent risk factors for mortality included residing outside Luanda, lack of outpatient follow-up, delayed symptom onset (>3 days), early disease manifestation (<8 months), and low hemoglobin (<7 g/dl).
  • Sickle cell-related deaths were linked to healthcare quality and access.

Conclusions:

  • Establishing regional sickle cell disease centers is crucial.
  • These centers can support patients and families, potentially reducing the disease burden.

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...

Factors Affecting Erythropoiesis

The cardiovascular system regulates the number of erythrocytes in the bloodstream to ensure optimal oxygen transport. It also prevents over-proliferation of these cells, which helps to maintain blood viscosity and flow rate.
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
EPO then...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
