Severe combined immunodeficiency: a case series from a paediatric hospital in Kenya.

Severe Combined Immunodeficiency (SCID) involves the lymphocyte lineage and mimics Human Immunodeficiency Virus (HIV) disease common in our region, making it difficult to diagnose and manage effectively. SCID in East Africa stands underdiagnosed because of lack of awareness and diagnostic resources. A case series of three SCID patients admitted to a Tertiary Paediatric Centre in Kenya between 2016 and 2019. The clinical presentations, laboratory findings, management and outcome for each were studied. Three cases were diagnosed between the ages of 4 to 15 months. Two of them were male and one was a female. All had a history of previous sibling death. There was no parental consanguinity. All presented with pneumonia. One of them had vaccine acquired Rotavirus infection and a persistent generalised maculopapular rash. The T, B cell profile was T- B- in two and T- B+ in one case and the immunoglobulins were reduced in all. All the cases were fatal. Thus, Primary immunodeficiency disorders are prevalent in East Africa. A proper clinical history, examination and laboratory tests like a haemogram, peripheral blood film can aid to suspect and diagnose SCID even with limited resources.

Joubert's syndrome and related disorders and home-based peritoneal dialysis in East Africa: a case report.

BACKGROUND: Joubert's syndrome is a rare condition affecting an estimated 1:80,000-1:100,000 individuals. There is underdevelopment of the cerebellar vermis resulting in a characteristic molar tooth sign on cross sectional axial magnetic resonance imaging. It can occur in association with multi-organ involvement; in such cases it is classified as Joubert's syndrome and related disorders. To date, there are no cases of Joubert's syndrome and related disorders from sub-Saharan Africa described in the literature. CASE PRESENTATION: An 8 year old black Kenyan female child was diagnosed in Joubert's syndrome in her first year of life. She was noted to have dysmorphic facies and hypotonia in the neonatal period and cranial MRI showed dysplasia of the cerebellar vermis and typical molar tooth malformation. She was subsequently lost to follow up for several years and later presented with anaemia. Further investigation revealed bilateral multicystic kidneys and significant renal impairment consistent with a diagnosis of end stage renal failure and polycystic kidney disease. She underwent home peritoneal dialysis for 7 months. CONCLUSIONS: Joubert's syndrome and related disorders is a rare condition. This case report demonstrates that home peritoneal dialysis is feasible in a low resource setting. Although it is scarcely provided in African countries, it is an effective renal replacement strategy for patients with end stage renal disease.
