Background: Systemic lupus erythematosus (SLE) is a rheumatic disease resulting in damage to any organ in the body.10-20% of SLE patients diagnosed in childhood.
Objective: To define the pattern of disease expression in pediatric SLE.
Sitting: Outpatient clinic of pediatric SLE of Abu Alrich hospital-Cairo-Egypt.
Subject: 25 pediatric SLE patients who attend the clinic.
Design of study: observational descriptive case series report.
Data collection: Data collected by second author during her residency in Abu Alrich hospital to study rheumatology. The 25 patients randomly selected. She collects medical history information directly from the patients and their parents and reviews their files to collect the other information (e.g.: investigation results and clinical examination and finding during course of the disease).
Results: From 25 patients Female to male ratio 2.3:1. Age at diagnosis range from 4 to 15 years with mean of 9 years. Duration of symptoms before diagnosis established range from one month to 7 years with mean of 8 months. Frequency of SLE classification criteria as follows: +ve ANA 95%, renal disorder: 84%, immunological disorder 60%, photosensitivity 48%, oral ulcers 48%, Hematological disorder 44%, arthritis 36%, serositis 28%, malar rash 12%, discoid rash 4%, neurological disorder 0%. Other clinical manifestation of SLE include fever 80%, arthralgia and anorexia 84% each, hair fall 40%, abdominal pain 36%, other skin manifestation 24%, headache 20%,dyspnea and palpitation 16% each, Reynard’s phenomena and lymphadenopathy 12% each. The most frequent hematological abnormality: elevated ESR: 100% anemia: 72%, leucopenia: 44%, thrombocytopenia: 20%, leukocytosis: 12%, thrombocytosis 8%, lymphopenia: 4%.
Conclusion and recommendation: The presentation and the clinical course of SLE have wide variability. Nephropathy, fever, anorexia and arthralgia were the most common presenting clinical manifestations in pediatric patients. There is marked delay between the starting of the disease manifestation and diagnosis, so alertness to the possibility of SLE as diagnosis in patients with variable manifestation should be there.

Systemic lupus erythematosus (SLE) is a rheumatic disease characterized by autoantibody directed against self-antigens, immune complex formation, and immune deregulation, resulting in damage to essentially any organ. Childhood S L E generally presents between the ages of 4 and 15 years, with girls out numbering boys 4:1.1 In 10-20% of SLE patients the diagnosis is made for the first time in childhood.2–6 The disease can affect any organ but the most frequent are the kidneys, skin, blood vessels and cells, joints, heart and SLE nervous system The patients may present with many years of symptoms or with acute history of life-threatening disease.7–9 Common initial and chronic complaints include fever, malaise, fatigue, joint pain, and temporary loss of cognitive abilities. Because they are so often seen with other diseases, these signs and symptoms are not part of the diagnostic criteria for SLE. When occurring in conjunction with other signs and symptoms they are considered suggestive.10 The American College of Rheumatology established eleven criteria as a classificatory instrument in 198211 which were revised in 199712 in clinical trials.
They were not intended to be used to diagnose individuals and do not do well in that capacity. For the purpose of identifying patients for clinical studies, a person has SLE if any 4 out of 11 symptoms are present simultaneously or serially on two separate occasions without other explanation. Classification criteria include:13 1- malar rash. 2- discoid rash. 3- serositis. 4-oral ulcers. 5- photosensitivity.6-arthritis .7-haematological changes (hemolytic anaemia, leucopenia, lymphopenia, thrombocytopenia) 8-Renal disorder. 9- +ve ANA. 10-Immunological disorder (eg: +ve double strand DNA, anti phospholipids anti body, anti smith). 11-CNS changes (eg: seizures, psycosis). The treatment of SLE involves preventing flares and reducing their severity and duration when they occur. It includes corticosteroids and anti-malarial drugs (hydroxychloroquin). Certain types of lupus nephritis such as diffuse proliferative glomerulonephritis require bouts of cytotoxic drugs. These drugs include azathioprin, mycophenolate, cyclophosphamide. Intra venous immunoglobulin also can be used in patients with multi organ involvement.14–16 Regarding prognosis SLE is incurable, but treatable. In the 1950s, most people diagnosed with SLE lived fewer than five years. Today over 90% survive for more than ten years, and many live relatively asymptomatically. 80-90% can expect to live a normal lifespan.17 We conduct this study to shade light on the clinical presentation of pediatric SLE.
Aim of study
To define the pattern of disease Expression (clinical and investigation) in patients with childhood onset systemic lupus erythematosus.
Settings
S L E Clinic (out patient clinic of pediatric SLE) of Abu Alrich hospital-Cairo Egypt.
Subject
25 pediatric SLE patients who follow the clinic.
Patients and method
Prospective- retrospective observational descriptive case series report.
Data collection
Data collected by second author during her residency in Abu Alrich hospital to study rheumatology. The 25 patients randomly selected. She collects medical history information directly from the patients and their parents and reviews their files to collect the other information (e.g.: investigation results and clinical examination finding during course of the disease).

There have been several studies dealing with childhood onset SLE and their results suggested that age at onset modifies the expression of the disease in terms of clinical presentation, pattern of organ involvement and serological findings.18 We used 14 years as cut off age as the most often used cut off ages are 14 or 16 years at onset of disease.19–21 The onset of SLE is rare before the age of 5 years.22 Mean age 11 years (range 5-14).23 Regarding age our study show similar results. Female predominant male but our ratio less than others24 may be because we didn’t take all of the patients but we choose random sample of them. Clinical presentation of our patients comparable to others25–27 but malar rash less and fever more. Our study show high percentage of renal involvement (84%) but lupus nephritis is probably present to some degree in all children with SLE and is a major determinant of a long term outcome.28–30 In our study no patient with neuropsychatric disorder Except for headache which made the most common neuropsychiatric disorder in SLE patients.31 Although the existence of a specific lupus headache and the optimal approach to headache in SLE cases remains controversial.32 And that’s why we didn’t include headache in neuropsychiatric manifestation of SLE. Regarding investigations our results similar to others.19,33,34 However, the small number of patients that have been analyzed, the disparity in selection criteria for patient inclusion, or the definition of the variables, and our study didn’t include all the SLE patients following the clinic make comparison of findings with previous reports difficult.
The presentation and the clinical course of SLE have wide variability. Nephropathy, fever, and arthralgia and anorexia were the most common in pediatric patients as presenting clinical manifestations. There is marked delay between the starting of the disease manifestation and diagnosis, so alertness to the possibility of SLE as diagnosis in patients with variable manifestation should be there.
