Abstract
OBJECTIVES We aimed to outline the demographic data, clinical spectrum, and treatment approach of sarcoidosis in a large group of patients and sought to figure out the variations of early-onset (EOS) and late-onset paediatric sarcoidosis (LOS). METHODS The study followed a retrospective-descriptive design, with the analysis of medical records of cases diagnosed as paediatric sarcoidosis. RESULTS Fifty-two patients were included in the study. The median age at disease onset and follow-up duration were 83 (28.2-119) and 24 (6-48) months, respectively. Ten (19.2%) cases had EOS (before 5th birthday) and 42 (80.7%) cases had LOS. The most common clinical findings at the time of the disease onset were ocular symptoms (40.4%) followed by joint manifestation (25%), dermatological symptoms (13.5%), and features related to multi-organ involvement (11.5%). Anterior uveitis was the most common (55%) one among ocular manifestations. Patients with EOS displayed joint, eye, and dermatological findings more commonly than patients with LOS. The recurrence rate of disease in patients with EOS (5.7%) and LOS (21.1%) were not statistically different (P = .7). CONCLUSIONS Patients with EOS and LOS may present with variable clinical features and studies addressing paediatric sarcoidosis cases in collaboration between disciplines will enhance the awareness of this rare disease among physicians and assist early diagnosis with lesser complications.

Abstract
Uveitis in children accounts for 5-10% of all cases. The causes vary considerably. Classically, uveitis is distinguished according to its infectious or inflammatory origin and whether it is part of a systemic disease or represents an isolated ocular disease. It is important to highlight the specificity of certain etiologies among children such as juvenile idiopathic arthritis. The development of visual function can potentially be hindered by amblyopia (children aged < 7 years), in addition to the usual complications (synechiae, macular edema) seen in adult patients. Moreover, the presentation of uveitis in children is often "silent" with few warning signs and few functional complaints from young children, which frequently leads to a substantial diagnostic delay. The diagnostic approach is guided by the presentation of the uveitis, which can be characterized by its location, and corresponds to the initial and main site of intraocular inflammation; its presentation, whether acute or chronic, granulomatous or not; and the response to treatment. Pediatricians have an important role to play and must be aware of the various presentations and etiologies of uveitis in children. Juvenile idiopathic arthritis is the most common etiology of pediatric non-infectious uveitis, but other causes must be recognized. Promptly initiated treatment before complications arise requires early diagnosis, recognition, and treatment. Any dependence on prolonged local corticosteroid therapy justifies discussing the introduction of a corticosteroid-sparing treatment considering the risk to develop corticoid-induced glaucoma and cataracts. Systemic corticosteroid therapy can be required for urgent control of inflammation in the case of severe uveitis. Long-lasting immunosuppressive treatment and biotherapies are most often prescribed at the same time to reinforce treatment efficacy and to prevent relapse and corticosteroid dependency. We review the different causes of uveitis, excluding infection, and the diagnostic and therapeutic management aimed at limiting the risk of irreversible sequelae.

Abstract
Sarcoidosis is a granulomatous inflammatory disease of uncertain cause. It occurs most commonly in young and middle-aged adults and less frequently in children; therefore, few data on pediatric sarcoidosis exist in the literature. The diagnosis and management of sarcoidosis remain challenging because of diverse and often nonspecific clinical and imaging findings. In addition, the clinical picture varies widely by age. Prepubertal and adolescent patients often present with adult-like pulmonary disease; however, early-onset sarcoidosis is typically characterized by the triad of arthritis, uveitis, and skin rash. Sarcoidosis is mostly a diagnosis of exclusion made by demonstrating noncaseating granulomas at histopathologic examination in patients with compatible clinical and radiologic findings. Although sarcoidosis often affects the lungs and thoracic lymph nodes, it can involve almost any organ in the body. The most common radiologic manifestation is pulmonary involvement, characterized by mediastinal and bilateral symmetric hilar lymphadenopathies with perilymphatic micronodules. Abdominal involvement is also common in children and often manifests as hepatomegaly, splenomegaly, and abdominal lymph node enlargement. Although neurosarcoidosis and cardiac sarcoidosis are rare, imaging is essential to the diagnosis of central nervous system and cardiac involvement because of the risky biopsy procedure and its low diagnostic yield due to focal involvement. Being familiar with the spectrum of imaging findings of sarcoidosis may aid in appropriate diagnosis and management. ©RSNA, 2023 Test Your Knowledge questions are available in the supplemental material.

Abstract
OBJECTIVE This retrospective study aimed to describe the clinical and radiological features, diagnostic methods, laboratory findings, organ involvement, and treatment strategies of 22 patients who followed up with late-onset childhood sarcoidosis and compare them with the literature. MATERIAL AND METHOD This retrospective multicenter study reviewed the medical records of 22 children with sarcoidosis who applied to the Pediatric pulmonology department of Erciyes University Faculty of Medicine and Necmettin Erbakan Faculty of Medicine in 2012 and 2022. RESULTS The mean age of the patients at the time of diagnosis was 13.1/year (interquartile range [IQR]1:6.3-[IQR]3:15.7). The most common first presenting symptom was cough 40.9% (n = 9), weight loss 31.8% (n = 7), and dyspnea 22.7% (n = 5). There were elevated levels of C-reactive protein (CRP; 59%), angiotensin-converting enzyme (ACE; 54.5%), erythrocyte sedimentation rate (ESR; 54.5%), and immunoglobulin G (IgG; 54.5%). Twenty patients (90%) received systemic steroid treatment. Eighteen (81.8%) of these patients responded positively to treatment. Two patients had a recurrence. CONCLUSION The incidence of sarcoidosis in children in Turkey is currently unknown. However, a regional average of 2.2 cases per year has been documented for the first time. Contrary to previous studies, a significant prevalence of consanguineous marriage was observed in our study. While constitutional symptoms were most common in other studies, the cough was the most common symptom in our study. To our knowledge, this is one of the Turkish studies with the highest number of sarcoidosis in children and one of the few European studies on sarcoidosis in children.

Abstract
Sarcoidosis is a systemic granulomatous disorder of unknown etiology characterized by granuloma formation. Due to the limited incidence of sarcoidosis in pediatric patients, little is known about the clinical course of this disease. A combination of clinical, radiologic, and pathologic examination is necessary to exclude other differential diagnoses (i.e., infection and granulomatous inflammatory disorder) and establish a diagnosis of sarcoidosis. Here, we report a case of histologically confirmed sarcoidosis initially misdiagnosed as hepatosplenic abscesses in an 11-year-old male. Treatment with corticosteroids improved his symptoms and resolved his skin and hepatosplenic lesions. A three-year follow-up was uneventful. This study emphasizes the importance of considering sarcoidosis in children presenting with findings of multi-organ involvement in the presence of histologic evidence of granuloma.

Abstract
Erythema nodosum (EN) is the most frequent form of panniculitis in children. We performed a literature review analyzing studies on pediatric EN published from 1990 to February 2022. EN is rare in pediatric age. It can be primary/idiopathic in 23–55% cases, or secondary in 47–77% cases. Secondary EN is related to a wide variety of conditions including infectious diseases, autoimmune disorders, malignancy, drugs, vaccinations, and pregnancy. The diagnosis of EN is clinical, based on the acute appearance of painful and red nodules localized to lower limbs, bilaterally distributed. If EN is diagnosed, basic work-up should include inflammatory markers, serum aminotransferases, lactate dehydrogenase, creatinine, protein electrophoresis, immunoglobulins, testing for streptococcal infection, and a tuberculin skin test. Based on the medical history and associated manifestations, further laboratory and radiological exams should be performed. The prognosis of EN is excellent, with spontaneous resolution in most patients within 2–6 weeks. Treatment, if needed, is addressed to the underlying condition. Despite being a rare manifestation in children, EN can be isolated or the first manifestation of a systemic or infectious condition. EN diagnosis is clinical, and a high index of suspicion is needed to perform investigations for the underlying disorders.

Abstract
PURPOSE To report a case of pediatric vascularized sarcoid choroidal granuloma complicated by placoid-like inflammation. METHODS Case report. RESULTS A 10-year-old girl presented with blurry vision in her right eye and a yellowish macular lesion that had been diagnosed as fibrotic choroidal neovascular membrane and observed for several months. On referral to our clinic, optical coherence tomography revealed a homogeneous hyperreflective lesion obliterating the choroidal vasculature and protruding under the retina with associated subretinal and intraretinal fluid. Optical coherence tomography angiography revealed vascularization of this granulomatous lesion, and the girl underwent six intravitreal injections of anti-vascular endothelial growth factor, with reabsorption of the fluid and consolidation of the lesion. A sudden, abrupt decrease in the visual acuity of the right eye 3 months after the last injection was accompanied on optical coherence tomography by hyperreflective inflammatory lesions breaking from the retinal pigment epithelium and involving the outer nuclear layer, all around the fibrotic granulomatous lesion. The girl was treated with oral steroids, and an extensive systemic evaluation revealed hilar adenopathy, thus posing the diagnosis of pediatric sarcoidosis complicated by placoid chorioretinopathy. CONCLUSION Atypical presentations of typical uveitic diseases are quite common in children. The presence of a foveal vascularized granuloma complicated by a placoid disorder should prompt the exclusion of infectious etiologies such as tuberculosis, to establish a therapy to preserve the child's vision.

Abstract
Sarcoidosis (SD) is a systemic granulomatous condition that is especially encountered in young adults and rarely in children, affecting predominantly the lungs and lymph nodes. We report the case of a 14-year-old teenage boy admitted to our clinic for nausea, vomiting, and weight loss. Clinical examination at the time of admission revealed malaise, pallor, and abdominal tenderness in the epigastric area at palpation. Laboratory tests revealed an elevated level of hemoglobin, mild thrombocytosis, increased erythrocyte sedimentation rate, and a mild increase in creatinine and urea levels along with hypercalcemia. An abdominal ultrasound revealed a right ectopic kidney, whereas the upper digestive endoscopy showed intense hyperemia and edema of the gastric mucosa. Thoracic computed tomography scan revealed giant hilar and mediastinal lymphadenopathy, along with multiple micronodules within the lung parenchyma and ground-glass aspect. The level of angiotensin-converting enzyme was high, parathormone was normal, and vitamin D level was low. Pathological examination of the bronchial, mediastinal, and lung biopsies established the diagnosis of SD. We administered oral corticosteroids for 2 months with outstandingly favorable outcome and no signs of recurrence 6 months after the cessation of the therapy.

Abstract
BACKGROUND Granulomatous diseases are a heterogeneous group of conditions characterized by an inflammatory infiltrate with a core of macrophages, epithelioid, giant cells and a corona of fibroblasts and lymphocytes. They are associated with a wide range of disorders such as mycobacterial and fungal infections, neoplasms, immunodeficiencies and systemic inflammatory disorders as sarcoidosis. CASE REPORT We report the case of a previously healthy 9-year-old male child who presented with persistent cough, diffuse lymphadenopathy, enlargement of liver and spleen and protracted fever. Anemia, lymphopenia and reduced platelet count was reported, with an increase of inflammatory markers. High levels of Angiotensin-converting enzyme and chitotriosidases were noted. A PET-CT scan showed increased uptake of 18 F-FDG glucose in multiple lymph nodes in thorax and abdomen and in the spleen. Biopsy of inguinal and bronchial nodes showed nodal granulomatous inflammation. The child was diagnosed with sarcoidosis and treated with corticosteroids with only transient efficacy. Further tests reported panhypogammaglobulinaemia and a reduced pool of B-memory lymphocytes. Thus, the diagnosis was revised to common variable immunodeficiency (CVID). CONCLUSION Common variable immunodeficiency is a heterogeneous condition with a highly variable clinical phenotype and a strong association with autoimmune disorders. The presence of noncaseating granuloma and pulmonary lesions, along with extrapulmonary features required a step by step approach to differentiate between CVID and sarcoidosis. This enables early introduction of immunoglobulin replacement therapy and decreases the morbidity and mortality of CVID.

Abstract
BACKGROUND Sarcoidosis is a disease of unknown etiology characterized by the formation of noncaseating, nonnecrotizing granulomas in various organ systems. METHODS Reviews of 84 cases of natural death with sarcoidosis between the years 1996 and 2017 autopsied at Wayne County. RESULTS The median age of decedents was 44 years (29 - 59 years of age). Blacks comprised 95% of the cohort, and 52% were female. Sarcoidosis or direct sequelae were the cause of death in 79% of cases. Twenty-nine percent of patients had a documented history of sarcoidosis and 70% of patients had evidence of systemic sarcoidosis. The most common sites of involvement were lungs or hilar lymph nodes (92%), heart (45%), liver (39%), and spleen (30%). Decedents with cardiac involvement were more likely to have no documented history of sarcoidosis (87% vs. 59%, p=0.004), more likely to have died of a sarcoidosis-related cause (97% vs. 65%, p<0.001), and died at a younger mean age (41 years vs. 46 years, p=0.001). In addition, individuals with cardiac involvement commonly had concurrent multiorgan involvement including lungs (90%), lymph nodes (38%), liver (40%), spleen (32%), and kidneys (7%). CONCLUSIONS Cardiac sarcoidosis is a uniquely poor prognostic factor and carries an increased risk of sudden death as shown by a disproportionate representation among medical examiner cases of sarcoidosis. Our findings suggest that approximately 40% may have asymptomatic cardiac involvement. The distribution of sarcoidosis within our cohort suggests that there is potentially a large undiagnosed and/or underdiagnosed demographic within large urban centers, such as Detroit, Michigan.

Abstract
Background Sarcoidosis in pediatric age is uncommon and challenging diagnosis, because manifestations can be significantly variable and non-specific since it is a multisystem disease, and virtually any organ system may be involved. Case presentation In this report, we describe the case of a 12-year-old girl presenting with fatigue and weight loss, with a painless hepato-splenomegaly without additional clinical signs on physical examination. In our patient, once we had ruled out infections, malignancies and granulomatous diseases of childhood, we made diagnosis of sarcoidosis, finding suggestive histological features in two different tissues (liver and lymph nodes) with lung involvement. Conclusions Our case points out that pediatricians should consider sarcoidosis in the differential diagnosis in case of systemic symptoms, even in absence of other specific clinical clues, because they represent the most common clinical manifestations on presentation in children, in order to refer promptly the young patient to specialist evaluation.

Abstract
BACKGROUND Childhood sarcoidosis is a very rare granulomatous disorder with an unknown etiology. Stage 1 disease is the most common whereas stages 2, 3, and 0 are rare in children. OBJECTIVE To evaluate thoracic findings of pediatric pulmonary sarcoidosis on MRI and to compare them with CT findings. METHODS Between August 2010 and May 2015, seven consecutive pediatric patients (four male, three female; age range: 8-18 years, mean age: 13.5 ± 3.01 years) who were diagnosed with sarcoidosis were enrolled in our study prospectively. Inclusion criterion was patients with stages 1-4 sarcoidosis who underwent contrast enhanced chest CT for initial diagnosis or follow-up evaluation of thoracic findings and exclusion criteria were patients with stage 0 disease with extra-pulmonary manifestations (n = 4). RESULTS Two patients who recovered from stage 2 to stage 0 were interpreted as normal. Five patients had abnormal findings on chest CT, including hilar/mediastinal lymphadenopathy (n = 5, 71%), nodules larger than 3 mm (n = 4, 57%), ground glass opacity (n = 4, 57%), thickening of the pleura/fissure (n = 3, 42%), interlobular septal thickening (n = 2, 28%), atelectasis (n = 1, 14%), consolidation (n = 1, 14%), bronchiectasis (n = 1, 14%), intraparenchymal and subpleural cysts (n = 1,14%), fibrotic bands (n = 1, 14%), and enlarged pulmonary artery (n = 1, 14%). Findings that were detected on CT but not observed by lung MRI were nodules <3 mm (n = 4, 57%), mild bronchiectasis and mild ground glass opacity (n = 1, 14%), and subpleural and intraparenchymal cysts (n = 1, 14%). The sensitivity and specificity of MRI were 85.2% and 100%, respectively. There was no statistically significant difference between lung MRI and CT in detecting the thoracic findings in stages 1, 2, and 4 sarcoidosis (P = 0.1336, 95%Cl). CONCLUSION Contrast-enhanced lung MRI with fast imaging sequences is a highly sensitive imaging modality and comparable with CT in evaluating both lung and cardiac abnormalities in pediatric sarcoidosis. Given there is no associated ionizing radiation, chest MRI is a promising imaging modality in this pediatric patient population. Pediatr Pulmonol. 2017;52:494-499. © 2016 Wiley Periodicals, Inc.

Abstract
Sarcoidosis is a rare disease, especially in the preschool age group where it usually presents with eye, joint, and skin involvement sparing the lungs. Multiple treatment regimes have been described with oral prednisolone being the usual first line treatment. We describe a case of a 4-year-old boy presenting with pulmonary sarcoidosis with no other organ involvement. The child was successfully managed with pulse intravenous methylprednisolone followed by oral prednisolone and has had a good outcome. This case reports a rare presentation of preschool sarcoidosis as well as the novel and successful use of pulse methylprednisolone in paediatric pulmonary sarcoidosis.

Abstract
RATIONALE High-resolution computed tomography (HRCT) plays an important role in the diagnosis and staging of pulmonary sarcoidosis, but implies radiation exposure. In this light, we aimed to describe HRCT findings as well as their relationship with pulmonary function tests (PFT) in children with pulmonary sarcoidosis. METHODS In a retrospective study, 18 pediatric patients with sarcoidosis, including 12 with pulmonary abnormalities (PA group) and 6 without pulmonary abnormalities (APA group) were followed over a 16-year period. Relationships between HRCT scores and PFT were studied by non-parametric Spearman's test at diagnosis and by restricted maximum likelihood (REML) analysis during follow-up. RESULTS Forty-three HRCT were scored. Twelve patients showed abnormal HRCT findings at diagnosis with multiple nodules or micronodules, while ground-glass opacities were seen in 11 patients. Ten patients exhibited pleural thickening or thickening of the fissure and 6 had interlobular septal thickening at diagnosis. No correlation between HRCT and forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), forced expiratory flow during the mid-half of the FVC (FEF(25-75)) and specific dynamical compliance (SpecC(Ldyn)) was found at diagnosis. However, linear mixed models showed that changes in total HRCT scores over time were significantly associated with SpecC(Ldyn), FVC, and FEV1 modifications. CONCLUSION Radiologic findings in children with pulmonary sarcoidosis were similar to those in adults. HRCT and PFT are both essential investigations at diagnosis; however, the correlation between HRCT pulmonary parenchymal findings and PFT over time suggests the possibility of reducing the number of HRCT during follow-up to decrease unnecessary radiation exposure.

Abstract
Sarcoidosis is a chronic granulomatous disease of unknown aetiology. It is extremely rare in children, especially the early onset form, presenting with eye, skin and joint symptoms but no lung involvement. We report an 11-month-old girl with granulomatous disease restricted to the lungs consistent with sarcoidosis. This unusual presentation has never been described in the paediatric literature so far.

Abstract
BACKGROUND Interstitial lung diseases (ILDs) in children represent a heterogeneous group of rare respiratory disorders that affect the lung parenchyma. After the launch of the French Reference Centre for Rare Lung Diseases (RespiRare®), we created a national network and a web-linked database to collect data on pediatric ILD. METHODS Since 2008, the database has been set up in all RespiRare® centres. After patient's parents' oral consent is obtained, physicians enter the data of children with ILD: identity, social data and environmental data; specific aetiological diagnosis of the ILD if known, genetics, patient visits to the centre, and all medical examinations and tests done for the diagnosis and/or during follow up. Each participating centre has a free access to his own patients' data only, and cross-centre studies require mutual agreement. Physicians may use the system as a daily aid for patient care through a web-linked medical file, backed on this database. RESULTS Data was collected for 205 cases of ILD. The M/F sex ratio was 0.9. Median age at diagnosis was 1.5 years old [0-16.9]. A specific aetiology was identified in 149 (72.7%) patients while 56 (27.3%) cases remain undiagnosed. Surfactant deficiencies and alveolar proteinosis, haemosiderosis, and sarcoidosis represent almost half of the diagnoses. Median length of follow-up is 2.9 years [0-17.2]. CONCLUSIONS We introduce here the French network and the largest national database in pediatric ILDs. The diagnosis spectrum and the estimated incidence are consistent with other European databases. An important challenge will be to reduce the proportion of unclassified ILDs by a standardized diagnosis work-up. This database is a great opportunity to improve patient care and disease pathogenesis knowledge. A European network including physicians and European foundations is now emerging with the initial aim of devising a simplified European database/register as a first step to larger European studies.

Abstract
The triad of rash, arthritis, and uveitis seems to be characteristic for early-onset childhood sarcoidosis. We describe an interesting case of early-onset childhood sarcoidosis coexisting enchondromatosis, which clinically masquerade as Langerhans cell histiocytosis. A 33 months old girl presented with skin rash, subcutaneous nodules with polyarthritis, and revealed the involvement of lymph nodes as well as spleen during work-up. She also presented with multiple osteolytic lesions which pathologically proven enchondromatosis. Oral prednisone was prescribed at 2 mg/kg/day for 2 months until when subcutaneous nodules and joint swellings almost disappeared, and then slowly tapered over a period of 5 months. We report an unusual case of early-onset childhood sarcoidosis presented with osteolytic bone lesions which were irrelevant to sarcoidosis.

Abstract
Childhood neurosarcoidosis is rare, and its etiology is unknown. La Crosse virus is one of the most common causes of encephalitis in North America. We report the case of a 12-year-old boy who had La Crosse virus encephalitis and subsequently developed imaging and pathologic findings suggestive of neurosarcoidosis. He presented with acute onset of transient aphasia 4 months after an episode of encephalitis; serology results at the time of aphasia were positive for La Crosse virus. Brain MRI revealed diffuse subcortical nodular lesions. His serum angiotensin-converting enzyme level was elevated, and brain biopsy revealed noncaseating granuloma. It is interesting to note that he has had no recurrence of aphasia; repeat MRI showed significant improvement of nodular lesions without therapy. To our knowledge, this is the first case of La Crosse virus encephalitis associated with neurosarcoid findings.

Abstract
Overlap in the clinical presentation of pediatric granulomatous inflammatory bowel disease may be substantial, depending on the mode of presentation. Chronic granulomatous disease (CGD) may present with granulomatous colitis, perianal abscesses, hepatic abscesses or granulomas, failure to thrive, and obstruction of the gastrointestinal tract (including esophageal strictures and dysmotility, delayed gastric emptying, and small bowel obstruction). Anemia, thrombocytosis, elevated C-reactive protein and erythrocyte sedimentation rate, and hypoalbuminemia are nonspecific and may occur in any of the granulomatous inflammatory bowel diseases. In histology, macrophages with cytoplasmic inclusions will be rather specific for CGD. Sarcoidosis may present with abdominal pain or discomfort, diarrhea, weight loss, growth failure, delayed puberty, erythema nodosum, arthritis, uveitis, and hepatic granulomata. Only in 55% of the patients will angiotensin-converting enzyme be elevated. The noncaseating epithelioid granulomata will be unspecific. Bronchoalveolar lymphocytosis and abnormalities in pulmonary function are reported in sarcoidosis and in Crohn disease (CD) and CGD. Importantly, patients with CD may present with granulomatous lung disease, fibrosing alveolitis, and drug-induced pneumonitis. Sarcoidosis and concomitant gastrointestinal CD have been reported in patients, as well as coexistence of CD and sarcoidosis in siblings. Common susceptibility loci have been identified in CD and sarcoidosis. CD and CGD share defects in the defense mechanisms against different microbes. In the present review, common features and essential differences are discussed in clinical presentation and diagnostics--including histology--in CGD, sarcoidosis, and CD, together with 2 other granulomatous inflammatory bowel diseases, namely abdominal tuberculosis and Hermansky-Pudlak syndrome. Instructions for specific diagnosis and respective treatments are provided.

Abstract
Childhood sarcoidosis is a rare multisystemic disorder that can have variable clinical presentations. A triad of skin, eye, and joint involvement is common in children younger than 5 years; however, pulmonary disease is more common in older children, similar to adults. The authors report the case of a 10-year-old girl who presented solely with massive splenomegaly. Her history was significant for iridocyclitis and unilateral sensorineural deafness at 6 and 7 years of age, respectively. A gallium scan showed diffuse splenic uptake, and the pathology of the spleen was consistent with a noncaseating granuloma, with no evidence of malignancy. A work-up for infectious etiology was unremarkable. This case demonstrates that the challenge in diagnosing sarcoidosis in young children stems from its ability to present in several unique clinical scenarios. It also reinforces the importance of tissue evaluation and the exclusion of other differential diagnoses, such as lymphoma, to confirm the diagnosis of sarcoidosis.

Abstract
Interstitial lung disease (ILD) in infants and children comprises a large spectrum of rare respiratory disorders that are mostly chronic and associated with high morbidity and mortality. These disorders are characterized by inflammatory and fibrotic changes that affect alveolar walls. Typical features of ILD include dyspnea, diffuse infiltrates on chest radiographs, and abnormal pulmonary function tests with restrictive ventilatory defect and/or impaired gas exchange. Many pathological situations can impair gas exchange and, therefore, may contribute to progressive lung damage and ILD. Consequently, diagnosis approach needs to be structured with a clinical evaluation requiring a careful history paying attention to exposures and systemic diseases. Several classifications for ILD have been proposed but none is entirely satisfactory especially in children. The present article reviews current concepts of pathophysiological mechanisms, etiology and diagnostic approaches, as well as therapeutic strategies. The following diagnostic grouping is used to discuss the various causes of pediatric ILD: 1) exposure-related ILD; 2) systemic disease-associated ILD; 3) alveolar structure disorder-associated ILD; and 4) ILD specific to infancy. Therapeutic options include mainly anti-inflammatory, immunosuppressive, and/or anti-fibrotic drugs. The outcome is highly variable with a mortality rate around 15%. An overall favorable response to corticosteroid therapy is observed in around 50% of cases, often associated with sequelae such as limited exercise tolerance or the need for long-term oxygen therapy.

Abstract
Interstitial lung diseases (ILDs) in children constitute a heterogeneous group of rare diseases that have been described and classified according to experiences and research in adults. However, pediatric pulmonologists have observed that the clinical spectrum is broader in children than in adults, and that many of these disorders have different courses and treatment responses. In addition, probably due to the various stages of lung development and maturation, new clinical forms have been described, particularly in infants. This has broadened the classification of ILDs in this age bracket. The understanding that neither the usual definition nor the standard classification of these disorders entirely apply to children has prompted multicenter studies designed to increase knowledge of these disorders, as well as to standardize diagnostic and therapeutic strategies. We have reviewed the conceptualization of ILDs in children, taking into consideration the particularities of this group of patients when using the criteria for the classification of these diseases in adults. We have also made a historical review of several multicenter studies in order to further understanding of the problem. We have emphasized the differences in the clinical presentation, in an attempt to highlight knowledge of newly described entities in young children. We underscore the need to standardize management of laboratory and radiological routines, as well as of lung biopsy processing, taking such knowledge into account. It is important to bear in mind that, among the recently described disorders, genetic surfactant dysfunction, which is often classified as an idiopathic disease in adults, should be included in the differential diagnosis of ILDs.

[PMID: 19246077 DOI: 10.1016/j.semarthrit.2008.12.001] [Citation(s) in RCA: 61] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2008] [Revised: 12/03/2008] [Accepted: 12/15/2008] [Indexed: 02/06/2023]
Abstract
OBJECTIVES We reviewed the literature to evaluate the role of common laboratory tests and to examine the recent progress in the laboratory diagnosis of pediatric rheumatic diseases. METHODS We used the PubMed database (1950-2008) to search for the keywords "laboratory," "erythrocyte sedimentation rate" (ESR), "C-reactive protein" (CRP), "blood cytology," "procalcitonin" (PCT), "complement system," "ferritin," "antistreptolysin O titer" (ASO), "autoantibodies," "genetic studies," in conjunction with "rheumatic disease in children" and "pediatric autoimmune diseases." All relevant original and review articles in English were reviewed as well as textbooks of pediatric rheumatology. RESULTS Laboratory tests (ESR, CRP, blood cytology, complement system, ferritin, ASO titer) play an important role in confirming a diagnosis and in the follow-up of rheumatic diseases in the pediatric age group. The ESR is probably the most widely measured index of the acute phase response. Measurement of CRP is very useful in the rapid diagnosis of infection as a progressive increase can be shown in the first 48 hours. Also, the subsequent fall in serum CRP concentration on resolution of inflammation is useful for monitoring the efficacy of treatment. In chronic diseases, a combination of CRP and ESR may provide the most useful information. Cytopenia and different forms of anemia can be encountered in many rheumatic diseases: they can be related to disease activity or to therapeutic side effects. Determination of complement levels (C3 and/or C4) is useful in the follow-up of systemic lupus erythematosus (SLE) and membranoproliferative glomerulonephritis. Ferritin is a laboratory hallmark of primary and secondary hemophagocytic lymphohistiocytosis. ASO titer should be obtained to confirm a diagnosis of acute rheumatic fever; other important antibody markers of streptococcal infection include antihyaluronidase, antideoxyribonuclease B, and antistreptokinase antibodies. We also found that, in the pediatric age, the main indication for synovial fluid analysis is suspected joint infection. Antinuclear antibodies, anti-Smith antigen, and anti-double-stranded DNA antibodies are important in the diagnosis of SLE, are useful prognostic markers, and facilitate clinical and treatment follow-up. Anti-SSA/Ro and anti-SSB/La antibodies are associated with Sjögren's syndrome and congenital heart block, while the anti-U1 small nuclear ribonucleoprotein antibodies show high specificity for mixed connective tissue disease. Repetitive spontaneous abortions, thrombocytopenia, and many types of venous or arterial thrombosis are associated with antiphospholipid antibodies. The presence of cytoplasmic antineutrophil antibodies is essential in the diagnosis of Wegener granulomatosis. The discovery of underlying single causative gene defects led to the identification of several autoinflammatory diseases, a group of genetic disorders characterized by recurrent attacks of inflammation (hereditary periodic fever syndromes). These include familial Mediterranean fever due to mutations in the Mediterranean fever (MEFV) gene, hyperimmunoglobulinemia D syndrome due to mutations in the MK gene for mevalonate kinase, cryopyrinopathies such as Muckle-Wells syndrome or neonatal-onset multisystemic inflammatory disease (neonatal-onset multisystemic inflammatory disease or chronic infantile neurological cutaneous and articular (CINCA)) associated with cold-induced autoinflammatory syndrome 1 gene mutations, and tumor necrosis factor receptor-associated periodic syndrome due to mutation of TNF receptor I gene. CONCLUSIONS Laboratory investigations play an important role in the diagnosis and follow-up of inflammatory rheumatic diseases in children. A good history and a complete physical examination are the best screening tests. Routine laboratory tests are useful to confirm a suspected diagnosis, to assess disease activity, and to measure the response and toxicity to treatment. Only a few tests represent diagnostic criteria such as antinuclear antibodies and anti-double-stranded DNA in SLE or cytoplasmic antineutrophil cytoplasmic autoantibodies in Wegener's granulomatosis. Recent advances in molecular genetics have impacted diagnosis, pathogenesis, and treatment in genetic fever syndromes.

Abstract
Childhood sarcoidosis is a rare multisystemic granulomatous disorder of unknown etiology. In the pediatric series reported from the southeastern United States, sarcoidosis had a higher incidence among African Americans. Most reported childhood cases have occurred in patients aged 13-15 years. Macrophages bearing an increased expression of major histocompatibility class (MHC) II molecules most likely initiate the inflammatory response of sarcoidosis by presenting an unidentified antigen to CD4+ Th (helper-inducer) lymphocytes. A persistent, poorly degradable antigen driven cell-mediated immune response leads to a cytokine cascade, to granuloma formation, and eventually to fibrosis. Frequently observed immunologic features include depression of cutaneous delayed-type hypersensitivity and a heightened helper T cell type 1 (Th1) immune response at sites of disease. Circulating immune complexes, along with signs of B cell hyperactivity, may also be found. The clinical presentation can vary greatly depending upon the organs involved and age of the patient. Two distinct forms of sarcoidosis exist in children. Older children usually present with a multisystem disease similar to the adult manifestations, with frequent hilar lymphadenopathy and pulmonary infiltrations. Early-onset sarcoidosis is a unique form of the disease characterized by the triad of rash, uveitis, and arthritis in children presenting before four years of age. The diagnosis of sarcoidosis is confirmed by demonstrating a typical noncaseating granuloma on a biopsy specimen. Other granulmatous diseases should be reasonably excluded. The current therapy of choice for sarcoidosis in children with multisystem involvement is oral corticosteroids. Methotrexate given orally in low doses has been effective, safe and steroid sparing in some patients. Alternative immunosuppressive agents, such as azathioprine, cyclophosphamide, chlorambucil, and cyclosporine, have been tried in adult cases of sarcoidosis with questionable efficacy. The high toxicity profile of these agents, including an increased risk of lymphoproliferative disorders and carcinomas, has limited their use to patients with severe disease refractory to other agents. Successful steroid sparing treatment with mycophenolate mofetil was described in an adolescent with renal-limited sarcoidosis complicated by renal failure. Novel treatment strategies for sarcoidosis have been developed including the use of TNF-alpha inhibitors, such as infliximab. The long-term course and prognosis is not well established in childhood sarcoidosis, but it appears to be poorer in early-onset disease.

Abstract
Uveitis is a manifestation of complex processes that can represent an infectious process or a dysfunction of the immune system that may have grave effects on the eye. Although infectious causes, once properly identified, may be successfully treated by addressing the inciting organism with recognized interventions, the immune-modulated chronic forms of uveitis often provide more complex challenges in management. Recent strides in understanding the inflammatory pathway and better bioengineering capabilities have resulted in some new modalities of treatment.

Abstract
A 10-year-old female was diagnosed as having early-onset sarcoidosis (EOS) after a prolonged skin disease. A granuloma emerged on the face at age 2 and massive lesions extended to the rest of the body. Repeated biopsies indicated histiocytic proliferation. At age 7, fever, disseminated macular eruptions, and multinucleated giant cells in the bone marrow prompted vinblastine and prednisolone therapy. Five months after stopping therapy, hypercalcemic crisis occurred along with fever, cytopenias, and interferon-gamma-nemia indicating a macrophage activation syndrome. A biopsy of nodules confirmed the diagnosis of sarcoidosis. The atypical EOS should be differentiated from histiocytosis.

Abstract
Pulmonary sarcoidosis is a rare disease in the pediatric age group, characterized by the presence of epitheloid-cell granulomas. In stage 3 sarcoidosis, pulmonary infiltrates without hilar lymphadenopathy occur. Definitive diagnosis requires a histopathological specimen, which might be difficult to obtain by transbronchial biopsy. Multidetector computed tomography (MDCT)-guided transthoracic lung biopsy (TLB) is a well-established procedure in adults, but has only rarely been applied in children.A 14-year-old boy was admitted to hospital for evaluation of a chronic systemic disease with severe pulmonary manifestation. All investigations, including bronchosopy and bronchoalveolar lavage with microbiological and virological testing, had been negative. MDCT-guided TLB was performed on a 16-section scanner with a low-dose protocol (single slices, 120 kV, 20 mAs), using a 16-gauge biopsy device. The total effective dose was 0.4 mSv for the biopsy procedure. Histopathological examination revealed multiple epitheloid-cell granulomas with giant cells in the absence of microbiological or virological abnormalities. A diagnosis of stage 3 pulmonary sarcoidosis was made and systemic anti-inflammatory therapy was administered, which led to complete remission within weeks. MDCT-guided TLB can be a valuable instrument in assessing pulmonary manifestations of pediatric sarcoidosis, enabling precise histopathological diagnosis and adequate therapy. The use of low-dose protocols can substantially reduce radiation exposure without relevant loss of image information. MDCT-guided lung biopsy should be considered prior to open-lung surgery in selected patients with unclear pulmonary disease.
