Background Multisystem inflammatory syndrome is a severe manifestation of SARS-CoV-2 in children. The incidence of MIS-C after infection is poorly understood. There are very few cohorts describing MIS-C in Africa despite MIS-C being more common in Black children worldwide. Methods A cohort of children with MIS-C and healthy children was recruited from May 2020 until May 2021 from the two main paediatric hospitals in Cape Town, South Africa. Clinical and demographic data were collected, and serum was tested for SARS-CoV-2 antibodies. The incidence of MIS-C was calculated using an estimation of population exposure from seroprevalence in the healthy group. Summary data, non-parametric comparisons and logistic regression analyses were performed. Results Sixty eight children with MIS-C were recruited with a median age of 7 years (3.6, 9.9). Ninety seven healthy children were recruited with a 30% seroprevalence. The estimated incidence of MIS-C was 22/100 000 exposures in the city in this time. Black children were over-represented in the MIS-C group (62% vs 37%, p = 0.002). The most common clinical features in MIS-C were fever (100%), tachycardia (98.5%), rash (85.3%), conjunctivitis (77.9%), abdominal pain (60.3%) and hypotension (60.3%). The median haemoglobin, sodium, neutrophil count, white cell count, CRP, ferritin, cardiac (pro-BNP, trop-T) and coagulation markers (D-dimer and fibrinogen) were markedly deranged in MIS-C. Cardiac, pulmonary, central nervous and renal organ systems were involved in 71%, 29.4%, 27.9% and 27.9% respectively. Ninety four percent received intravenous immune globulin, 64.7% received methylprednisolone and 61.7% received both. Forty percent required ICU admission, 38.2% required inotropic support, 38.2% required oxygen therapy, 11.8% required invasive ventilation and 6% required peritoneal dialysis. Older age was an independent predictor for the requirement for ionotropic support (OR = 1.523, CI 1.074, 2.16, p = 0.018). The median hospital stay duration was 7 days with no deaths. Conclusion The lack of reports from Southern Africa does not reflect a lack of cases of MIS-C. MIS-C poses a significant burden to children in the region as long as the pandemic continues. MIS-C disproportionately affects black children. The clinical manifestations and outcomes of MIS-C in this region highlight the need for improved surveillance, reporting and data to inform diagnosis and treatment.

Background Pediatric Rheumatology is an orphan specialty in Africa which is gradually gaining importance across the continent. Main body This commentary discusses the current state of affairs in the sphere of Pediatric Rheumatology across Africa and offers practical strategies to navigate the challenges encountered in research, models of care, education and training. We outline the establishment, opportunities of growth and achievements of the Pediatric Society of the African League Against Rheumatism (PAFLAR). Conclusion This commentary lays the foundation for establishment of a formidable framework and development of partnerships for the prosperity of Pediatric Rheumatology in Africa and beyond.
Background The word scleroderma means ‘hard skin’ that develops due to excessive accumulation of collagen. It is the third most frequent rheumatic disease in paediatric rheumatology after juvenile idiopathic arthritis and systemic lupus erythematosus. When it occurs in individual <16 years, it is called juvenile scleroderma. It is a rare disease that occurs in one per million children, documented to be more common in African adults with poorer survival states compared with Caucasians. Objectives To describe the clinical and laboratory characteristics of children with juvenile scleroderma seen in our clinic, thus, increasing its awareness. Methods Retrospective review of records of three children diagnosed with juvenile scleroderma at the paediatric Rheumatology Clinic of Lagos State University Teaching Hospital(LASUTH) between May 2018 to April 2022. Results Case 1 A 12-year-old girl presented with skin tightness of the left hand and thigh of one year, contracture of the 3rd, 4th and 5th proximal interphalangeal joints, arthritis of the left wrist, skin induration of the dorsum of the left hand involving the 4th and 5th finger and extending to the wrist and skin and induration of the anterolateral aspect of the left thigh. Her blood tests showed an erythrocyte sedimentation rate (ESR) at 20 mm/h, an ANA titre of 1:2560, a negative anti-Scl 70/anti-centromere antibodies, a normal complete blood count and serum electrolytes/urea/creatinine. A diagnosis of linear scleroderma was made, the patient had prednisolone, methotrexate and folic acid, in addition to topical emollients. She improved clinically as observed during follow up visits six weeks after initiation of treatment but later defaulted from the clinic due to unknown reason. Case 2 A 4-year-old girl presented with constitutional symptoms, swollen hands and feet, sclerodactyly, narrowing of oral aperture, ulcers at tips of the fingers, inflammatory pain of the large joints, hypopigmented macules on the face, trunk, abdomen and back and also abnormal capillaroscopy. Erythrocyte sedimentation rate was 22 mm/h with normal levels of electrolytes/urea/creatinine, thrombocytosis, ANA titre of 1:640 and negative anti-centromere and anti-U1RNP antibodies. A diagnosis of diffuse systemic sclerosis was made. She started prednisolone, methotrexate, nifedipine and omeprazole and was asked to do an ECG, an Echocardiogram, a spirometry and a chest HRCT but she couldn’t afford to do these investigations due to severe financial constraints. She was clinically stable for four months until she presented at the emergency room with sudden loss of consciousness and congestive cardiac failure. She died during resuscitation attempt. Case 3 An 11-year-old girl known patient of haematology unit with sickle cell anaemia, presented with inflammatory arthritis of the small joints of the hands, elbows and knees of nine-month duration, sclerodactyly, contractures of the PIP of the fingers, narrowing of oral aperture, generalized hypopigmented macules and abnormal nailfold capillaroscopy. Investigation showed an ANA titre of 1:640, positive anti-Scl 70 antibodies, negative anti-centromere antibodies, ESR of 130 mm/h and thrombocytosis. The echocardiogram showed a normally structured heart with severe restriction on spirometry and features of interstitial lung disease on HRCT of the chest. She started mycophenolate mofetil, prednisolone and nifedipine. She later received 2 doses of rituximab due to slow clinical improvement. She is being followed up. Conclusion Most data on scleroderma are from adult studies, we reported these three cases due to the rare occurrence of scleroderma in children, thus increasing its awareness.
