Insights

Access to care for children with rare genetic neuromuscular diseases (GNMDs) in Zambia is limited. Disparities exist between recommended and utilized health services, highlighting the need for improved diagnostics and interventions.

Area of Science:

  • Neurology
  • Genetics
  • Pediatrics

Background:

  • Medical and rehabilitative care for rare genetic neuromuscular diseases (GNMDs) has advanced significantly in developed nations.
  • However, a lack of data on GNMDs in sub-Saharan Africa risks exacerbating existing health inequities.
  • This study addresses the critical need for information on pediatric GNMDs in this region.

Purpose of the Study:

  • To investigate the current health service utilization and needs of children with rare genetic neuromuscular diseases (GNMDs) in Zambia.
  • To identify disparities between recommended and accessed care for pediatric GNMD patients.
  • To inform strategies for improving healthcare access and outcomes for GNMDs in sub-Saharan Africa.

Main Methods:

  • A cross-sectional study was conducted with 50 probands diagnosed with GNMDs at the University Teaching Hospital in Lusaka, Zambia.
  • Data collection involved interviews with probands/caregivers and independent assessments by a neuromuscular neurologist and physiotherapist.
  • Diagnoses were based on available clinical and electrophysiologic data; molecular findings were not yet analyzed.

Main Results:

  • The study included 50 probands (52% male, median age 12 years), with motor neuron diseases, muscle disorders, and inherited polyneuropathies being the most common diagnoses.
  • A significant proportion of cases (15%) lacked sufficient data for definitive classification.
  • Patient/caregiver-reported access to recommended health services outside of primary care was challenging for 69% of participants, revealing substantial gaps between recommended and actual care utilization.

Conclusions:

  • Improved diagnostic and therapeutic paradigms are essential for managing rare genetic neuromuscular diseases (GNMDs) in Zambia.
  • Establishing multidisciplinary clinics holds promise for enhancing access to and utilization of necessary health services.
  • Further qualitative research is crucial to address referral pathways, access barriers, and the overall quality of care for pediatric GNMD patients in the region.

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Sex-linked Disorders01:43

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Genetic Screens02:46

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
