ABSTRACT

Retropharyngeal infections (RPIs) are uncommon in young infants and are difficult to diagnose due to their non-classical presentation. RPI can occasionally be complicated with multiple cranial nerve palsies but rarely in isolation. Isolated hypoglossal nerve palsy (HNP) due to RPI has been described in the literature but mostly in older children and adults. Assessment for hypoglossal nerve function is challenging in a young infant because the conventional signs of hypoglossal nerve dysfunction are difficult to elicit in this age group. Early recognition and treatment of RPI are associated with good HNP recovery. We present a case of a young infant with tongue deviation and difficulty with feeding attributed to an isolated HNP caused by suppurative retropharyngeal lymphadenitis. The infant underwent incision and drainage with complete recovery of the tongue function after 8 weeks.

ABSTRACT

Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is the most common periodic fever syndrome in pediatric patients. It is clinically characterized by fever flares lasting 3-7 days, reappearing every 2-8 weeks with a distinctive clockwork regularity. PFAPA generally begins before 5 years of age and usually ceases 3-5 years after onset. Recurrences may be observed in adolescence and adulthood in up to 20% of cases. The authors aim to describe a case of PFAPA recurrence in adolescence temporally associated with allergen-specific immunotherapy (ASIT). A 16-year-old female patient was referred to the rheumatology unit due to recurrent episodes of fever one month after initiating ASIT for allergic rhinitis. These episodes occurred every 4 weeks and lasted 3 days. During these episodes, she also presented with a sore throat, tonsillar exudates, and cervical lymphadenopathy. Abortive treatment with oral prednisolone was attempted in these episodes, with complete resolution of fever after a single dose. After reviewing her medical background, she had previously experienced febrile episodes accompanied by aphthous ulcers and tonsillar exudates occurring every 7-8 weeks from age 2-7. The etiopathogenesis of PFAPA remains uncertain. Environmental triggers, particularly those with immunomodulator effects, may interfere with the immune responses responsible for PFAPA occurrence, but the mechanisms are still unclear. The authors describe the first report of the reappearance of PFAPA flares, possibly due to ASIT. Further studies are needed to fully clarify if ASIT constitutes a true environmental trigger of PFAPA.

ABSTRACT

Background: Tuberculosis is a chronic infectious disease and can be categorised into pulmonary TB and extra-pulmonary TB based on its spread. TB lymphadenitis is one of the extra-pulmonary TB diseases. Patients with a weakened immune system in systemic lupus erythematosus (SLE) have an increased incidence of TB. Case: Here we present a case report of a 21-year-old female patient with SLE diagnosed with tuberculous lymphadenitis at dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia. The patient complained of a lump in the right neck 4 months ago with a diameter of 4 cm, accompanied by fever, decreased appetite, and weight loss. Other than that, the patient also experiences joint pain, hair loss and sun sensitivity since 12 months ago. Chest radiography showed no abnormalities, and fine-needle aspiration biopsy results confirmed tuberculous lymphadenitis. Antinuclear antibody test was borderline. The patient had been taking steroids and hydroxychloroquine for the past 10 months. Currently, the patient is taking the advanced phase of antituberculosis drugs FDC. After undergoing the intensive phase of antituberculosis drugs, the submandibular lump got smaller to a diameter of 2 cm. Conclusion: TB lymphadenitis is a rare case but can occur in conditions of decreased immunity like SLE. It involves some of the immune disorders caused by the long-term use of immunosuppressive therapy.

ABSTRACT

OBJECTIVE: Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is the most common periodic fever syndrome in children; by definition, episodes occur every 2 to 8 weeks. However, in a subset of our patients, we noticed a higher frequency of attacks, of less than 2 weeks, which we refer to as extreme PFAPA (ePFAPA). This group consisted of patients who were extreme upon presentation of PFAPA, and those who became extreme after initiation of abortive corticosteroid treatment. We aimed to characterize demographic and clinical features of ePFAPA, including the two groups, and to compare them to patients with non-extreme PFAPA (nPFAPA). STUDY DESIGN: The medical records of 365 patients with PFAPA who attended Schneider Children's Medical Center of Israel from March 2014 to April 2021 were reviewed. Patients with concomitant familial Mediterranean fever were excluded. Characteristics of the ePFAPA (including subgroups) and nPFAPA groups were compared using Wilcoxon rank sum, Pearson's chi-squared, and Fisher's exact tests. RESULTS: Forty-seven patients (12.9%) were identified as having ePFAPA. Among patients with ePFAPA, compared to patients with nPFAPA, the median (interquartile range) age at disease onset was earlier: 1.5 years (0.7-2.5) vs. 2.5 years (1.5-4.0), P < 0.001; and diagnosis was younger: 2.6 years (2.0-3.6) vs. 4.5 years (3.0-6.2), P < 0.001. A higher proportion of patients with ePFAPA than nPFAPA were treated with colchicine prophylaxis (53% vs. 19%, P < 0.001), but symptoms and signs during flares did not differ significantly between these groups. Demographic and clinical characteristics were similar between patients with ePFAPA from presentation of PFAPA (22, 47% of those with ePFAPA) and ePFAPA from after corticosteroid treatment. CONCLUSION: About half the patients categorized with ePFAPA syndrome already had extreme features upon presentation. Patients with ePFAPA compared to nPFAPA presented and were diagnosed at an earlier age.

ABSTRACT

Epstein-Barr virus (EBV) infection may present with fulminant constitutional symptoms, cytopenia(s), and systemic lymphadenopathy, raising clinical suspicion for lymphoma and prompting lymph node and bone marrow biopsies. At the microscopic level, the histopathologic findings in cases of acute EBV lymphadenitis may mimic certain lymphoid neoplasms, creating a range of differential diagnoses and diagnostic pitfalls.We present a case of fulminant EBV infection in an adolescent whose clinical and radiographic findings led to lymph node and bone marrow biopsies to rule out lymphoma. One week after being diagnosed with acute EBV infection (infectious mononucleosis), a 17-year-old Caucasian male presented with worsening symptoms including persistent fever, progressive, painful lymphadenopathy, and splenomegaly. A peripheral blood smear showed lymphocytosis with many reactive lymphocytes, anemia, and thrombocytopenia. Laboratory studies showed elevated ferritin, triglycerides, and soluble IL-2/CD25. A cervical lymph node biopsy demonstrated an EBV-positive, reactive B-immunoblast proliferation with large atypical lymphoid cells mimicking Reed-Sternberg cells of Hodgkin lymphoma, in addition to patchy vasculitis, coagulative necrosis, and prominent hemophagocytic activity. Bilateral bone marrow biopsies showed a hypercellular marrow with patchy infiltrates of similar EBV-positive, large atypical lymphoid cells, as well as prominent hemophagocytic activity. The diagnosis of acute EBV associated lymphoproliferation with concurrent hemophagocytic lymphohistiocytosis (HLH) was rendered.Recognition of common and uncommon clinical presentations of acute EBV infection is essential, particularly when histopathologic findings raise suspicion for a possible hematolymphoid neoplasm. Both the lymph node architectural and viral cytopathic changes observed in EBV lymphadenitis exhibit significant morphologic overlap with classic Hodgkin lymphoma (cHL) and several other lymphomas, including anaplastic large cell lymphoma, diffuse large B cell lymphoma, and angioimmunoblastic T cell lymphoma. Recognition of immunohistochemical staining patterns in EBV lymphadenitis is critical to avoid misdiagnosis. Conversely, bona fide lymphoma, particularly cHL, can masquerade as EBV infection. We provide a concise discussion and tables of the histopathologic differential diagnosis of EBV lymphadenitis, including cHL and other lymphomas. Pathologists should include acute EBV infection within the differential diagnosis when confronted with clinical and pathologic findings concerning for lymphoma, particularly in adolescents and young adults.

ABSTRACT

BACKGROUND: Lymphadenitis is the most common extrapulmonary tuberculosis (EPTB) manifestation. The microbiome is important to human health but uninvestigated in EPTB. We profiled the site-of-disease lymph node microbiome in tuberculosis lymphadenitis (TBL). METHODS: Fine-needle aspiration biopsies were collected from 158 pretreatment presumptive TBL patients in Cape Town, South Africa. 16S Illumina MiSeq rRNA gene sequencing was done. RESULTS: We analysed 89 definite TBLs (dTBLs) and 61 non-TBLs (nTBLs), which had similar α- but different ß-diversities (p=0.001). Clustering identified five lymphotypes prior to TB status stratification: Mycobacterium-dominant, Prevotella-dominant and Streptococcus-dominant lymphotypes were more frequent in dTBLs whereas a Corynebacterium-dominant lymphotype and a fifth lymphotype (no dominant taxon) were more frequent in nTBLs. When restricted to dTBLs, clustering identified a Mycobacterium-dominant lymphotype with low α-diversity and non-Mycobacterium-dominated lymphotypes (termed Prevotella-Corynebacterium, Prevotella-Streptococcus). The Mycobacterium dTBL lymphotype was associated with HIV-positivity and features characteristic of severe lymphadenitis (eg, larger nodes). dTBL microbial communities were enriched with potentially proinflammatory microbial short-chain fatty acid metabolic pathways (propanoate, butanoate) vs nTBLs. 11% (7/61) of nTBLs had Mycobacterium reads BLAST-confirmed as Mycobacterium tuberculosis complex. CONCLUSIONS: TBL at the site-of-disease is not microbially homogeneous. Distinct microbial community clusters exist that, in our setting, are associated with different clinical characteristics, and immunomodulatory potentials. Non-Mycobacterium-dominated dTBL lymphotypes, which contain taxa potentially targeted by TB treatment, were associated with milder, potentially earlier stage disease. These investigations lay foundations for studying the microbiome's role in lymphatic TB. The long-term clinical significance of these lymphotypes requires prospective validation.

ABSTRACT

INTRODUCTION: Rosai Dorfman disease (RDD) is a rare benign histiocytic proliferative disorder of lymph node sinuses. Langerhans cell histiocytosis (LCH) is a solitary or multisystem clonal proliferation of abnormal dendritic cells (Langerhans cells) with varied presentations. The co-occurrence of these two entities is quite rare. CASE DESCRIPTION: A six-year-old boy presented with multiple mass lesions in the neck since two years and a nodular lesion in right upper eyelid for the past 4 months. He was diagnosed with tubercular lymphadenitis 2 years back, and was given a course of anti-tubercular therapy (ATT) elsewhere. No improvement was seen. Fine needle aspiration cytology (FNAC) of the cervical lymph nodes revealed reactive lymphadenitis while lymph node biopsy showed features of RDD. Excision biopsy of the orbital mass showed features of both RDD and LCH. The patient was started on tablet prednisolone. Six months later, complete resolution of lymph node enlargement and remaining orbital mass was noted. Post operative contrast enhanced Magnetic Resonance Imaging of head and neck was normal. CONCLUSION: The coexistence of RDD and LCH may be a result of divergent differentiation from a common lineage or a de novo phenotypic evolution.

ABSTRACT

Periodic fever, aphthous stomatitis, pharyngitis, adenitis (PFAPA) syndrome is one of the most common autoinflammatory fever disorders in the childhood which may co-exists with familial Mediterranean fever (FMF) causing treatment complexity. As the role of surgery in PFAPA syndrome is still controversial, in this paper, our aim is to present our results of tonsillectomy/adenotonsillectomy in the treatment of PFAPA syndrome. Archives of a tertiary care hospital were investigated for patients who underwent tonsillectomy or adenotonsillectomy due to PFAPA Syndrome between 2010 and 2020. 344 patients were found but only 281 of them were accessible. Through phone call interview and chart review methods, preoperative and postoperative the number and severity of the attacks and general satisfaction after the operation were recorded and analyzed. Also, patients with concomitant FMF were analyzed separately. A total of 281 patients were included in the study. There was no improvement in 10 (3.55%) patients. Eight (2.84%) patients showed mild improvement, 29 (10.32%) patients had moderate improvement and 234 (83.27%) patients had full recovery after tonsillectomy. There were 266 PFAPA patients without FMF. No improvement, mild improvement, moderate improvement, and full recovery in this patient group were 5 (1.9%), 6 (2.3%), 25 (9.4%) and 230 (86.5%), respectively. FMF was present in 5.33% (15/281) of the patients. In PFAPA + FMF group 5 patients had no improvement (33.3%), 2 had mild improvement (13.3%), 4 had moderate improvement (26.7%) and 4 had full recovery (26.7%). Benefit of tonsillectomy was significantly lower in the patients with concomitant FMF when compared to the patients who did not have FMF (p < 0.001). Age of diagnosis, age of operation, severity of the disease, type of operation, and gender were found to have no significant relationship with the benefit from surgery (p < 0.05). According to the findings of this study, tonsillectomy is an effective long-term treatment for PFAPA syndrome with success rate of 83.27%. Also, preoperatively FMF should be considered in these patients, which dramatically reduces surgical efficacy.

ABSTRACT

Fever is a common symptom of infection in children. Periodic fever syndromes are less common but more complex. One of these Periodic fever syndromes is PFAPA (periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis) syndrome which is known as the most benign syndromes. The cause of this disease is unknown. Various factors, including environmental and genetic factors, are involved in the development of this disease. In this study, the association of rs13075270 and rs13092160 polymorphisms were investigated in CCR1 and CCR3 genes with susceptibility to this syndrome in the Chinese population. In this regard, 38 patients with PFAPA syndrome and 100 healthy individuals were selected. After DNA sampling and extraction, polymorphisms of CCR1 and CCR3 receptor genes were examined by the PCR-RFLP method. Findings were analyzed using SPSS software version 22 with a significant level of P <0.05. The frequency of T/T genotype rs13092160 polymorphism in the patient and control groups was 78.95% and 83%, respectively, C/T genotype was 21.05% and 17% (P = 0.421). The frequency of the C/C genotype was 0 in both groups. Regarding rs13075270 polymorphism, the frequency of T/T genotype in patient and control groups was 15.79% and 81%, C/T genotype was 78.95% and 18% and C/C genotype was 5.26% and 1%, respectively (P<0.05). Thus, in rs13075270 polymorphism, the C/T genotype was associated with the risk of PFAPA syndrome (P<0.05), but rs13092160 polymorphism did not show a significant difference between individuals with PFAPA syndrome and controls.

ABSTRACT

OBJECTIVE: To describe clinical, diagnostic and therapeutic characteristics of the periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) syndrome. DATA SOURCE: Literature review in the PubMed database by using specific descriptors to identify all articles published in the English language in the last three years; 38 articles were found. After performing selection of titles and abstract analysis, 13 out of the 38 articles were fully read. Relevant studies found in the references of the reviewed articles were also included. DATA SYNTHESIS: The PFAPA syndrome (Periodic Fever, Aphthous Stomatitis, Pharyngitis and cervical Adenitis) is a medical condition grouped among the periodic fever syndromes. The etiology is uncertain, but possibly multifactorial, and its symptoms are accompanied by recurrent febrile episodes although weight and height development are preserved. It is a self-limiting disease of benign course with remission of two to three years without significant interference in the patient's overall development. Treatment consists of three pillars: interruption of febrile episodes, increase in the interval between episodes, and remission. CONCLUSIONS: Despite several attempts to establish more sensitive and specific criteria, the diagnosis of PFAPA syndrome is still clinical and reached by exclusion, based on the modified Marshall's criteria. The most common pharmacological options for treatment include prednisolone and betamethasone; colchicine may be used as prophylaxis, and surgical treatment with tonsillectomy can be considered in selected cases.

ABSTRACT

OBJECTIVES: To describe a homogeneous group of patients with undifferentiated recurrent fevers followed-up in a tertiary referral center for systemic autoinflammatory diseases (SAIDs). METHODS: Patients with undifferentiated recurrent fevers seen at our Center from 2008 to 2021 and followed-up for at least one year were included in a retrospective study. Monogenic recurrent fevers, patients carrying variants of unknown origin and PFAPA (Periodic Fever, Aphthous Stomatitis, Pharyngitis, Adenitis) syndrome were excluded. RESULTS: Fifty patients (34 male, 16 female) were included in the study. The median age at onset was 3 years, and the median follow-up was 3.3 years. At baseline, arthralgia (70%) and abdominal pain (65%) were the most frequent manifestations. NSAIDs or steroids on demand had a variable and transient effect. Tonsillectomy was ineffective in the 10 patients (20%) that underwent surgery. Forty-eight patients (96%) were treated with colchicine. A complete response (absence of fever) was achieved in 31 patients (64.6%). Nine patients (18%) showed a partial response, with a median reduction of fever episodes per year of 72%. Nine patients (16.7%) were considered resistant to colchicine. The presence of generalized lymphadenopathy and, to a lesser extent, exudative tonsillitis was associated with a lack of response to colchicine. CONCLUSIONS: We describe the largest series of patients with syndrome of undifferentiated recurrent fever (SURF) reported in the literature so far. SURF should be considered as a distinct clinical entity in the context of multifactorial autoinflammatory diseases.

ABSTRACT

Kawasaki disease (KD) is a systemic vasculitis syndrome that mostly affects children under 4 years old. Among the reported KD cases, only 1% were over 10 years old. We herein report 2 cases of adult-onset KD (AKD) in 19- and 17-year-old boys diagnosed with a persistent fever and cervical lymphadenitis. Both patients showed cardiac complications, such as coronary artery dilation and myocarditis. Repeated intravenous immunoglobulin therapy was effective in the 19-year-old, while plasma exchange therapy was needed for the 17-year-old, with no sequelae noted at discharge. KD should be considered as a differential diagnosis for persistent fever in adults.

ABSTRACT

BACKGROUND: Histological evaluation of lymph node is crucial for the definitive diagnosis of Kikuchi-Fujimoto disease (KFD). However, lymph node biopsy under local anesthesia is often difficult in pediatric patients. OBJECTIVES: We evaluated cytological findings for pediatric patients with prolonged cervical lymphadenitis clinically suggestive of KFD and investigated the clinical characteristics of patients diagnosed with KFD by fine-needle aspiration cytology (FNAC). METHODS: This retrospective clinical study included 58 Japanese pediatric patients with cervical lymphadenitis who underwent FNAC. RESULTS: Cytological diagnosis was KFD for 22 and suspicion of KFD for 11 patients. The remaining 25 patients were diagnosed with non-specific lymphadenitis (NSL). Tenderness was independently associated with a higher frequency of both KFD in narrow and broad senses, compared with NSL (p = .009; p = .038). The percentage of patients who underwent FNAC within 28 days from symptom onset tended to be higher among patients with KFD in a narrow sense than those with NSL (p = .052). CONCLUSION: This study indicated that the period from symptom onset to FNAC (<28 days) and the symptom of tenderness were associated with the cytological diagnosis of KFD.

ABSTRACT

INTRODUCTION: As a recurrent disease, periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is characterized by episodes of febrile attacks and is often prominent in children under five years of age. However, the etiology of this condition has not been fully understood yet. MATERIALS AND METHODS: The search in the extensive literature of peer-reviewed articles published from the inception to December 2021 was conducted to identify the relevant studies, using the electronic databases of MEDLINE/PubMed, Embase, Scopus, the Cochrane Library, and the Web of Science. RESULTS: The analysis of complex relationships indicates that inflammatory factors, such as various cytokines and acute-phase proteins (APPs), play leading roles in the pathogenesis of this disease. Accordingly, this article summarizes the current state of knowledge to explain the mechanisms involved in inflammatory responses among patients with PFAPA syndrome and investigate its role in the pathogenesis of this disease. Moreover, the possibilities for further implementation of new therapeutic strategies are pointed out. CONCLUSION: It is concluded that some pathophysiological processes are associated with immune dysregulation, which itself may be secondary to environmental factors, genetic background, and underlying diseases, including latent infections that multiply inflammatory mediators. elevated inflammatory markers similarly play a significant part in the clinical outcomes of this condition, whose pyrogenic nature is the reason for the development of episodes of febrile attacks in the population of patients suffering from PFAPA syndrome.

ABSTRACT

BACKGROUND: Fever is the most frequent reason for medical consultation in children, and makes up 15-25% of all consultations in primary care and emergency departments. In here we report a case of a 13 year-old girl who referred with an unusual presentation of fever and was misdiagnosed with recurrent urinary tract infection for 8 years. CASE PRESENTATION: This is a Clinical Reasoning Cycle case study. A 13 year-old girl was referred with a chief complaint of recurrent fevers from 8 years. During her first febrile episode, she had a 5-day high-grade fever associated with loss of appetite. Her physical examination at that time was unremarkable. Blood tests showed leukocytosis with a shift to the left and urine examination was in favor of pyuria. The urine culture was positive for bacterial growth. The episodes of fever were repeated every 45 days. Accordingly, the patient was diagnosed as a case of recurrent urinary tract infection. In the intervals between her febrile episodes, the patient was healthy and laboratory tests were normal. Ultrasonography, voiding cystourethrogram and dimercaptosuccinic acid scans were normal. During her last visit, the patient mentioned difficulty in swallowing and on examination cervical lymph nodes, exudative tonsillitis and painful aphthous stomatitis were detected. All antibiotics were stopped and corticosteroids were started. The patient's symptoms were relieved and the interval between her febrile episodes became longer. CONCLUSIONS: Our study shows that a patient should never be marked, particularly when the symptom and signs aren't completely justifying a patient's condition.

ABSTRACT

CONTEXT.­: Drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms (DRESS) is a drug-induced, adverse T-cell-mediated hypersensitivity reaction that most often involves skin. The pathologic findings of DRESS-related lymphadenopathy have been described infrequently in the literature. OBJECTIVE.­: To present a case series of DRESS-related lymphadenopathy with an emphasis on the morphologic spectrum. DESIGN.­: We describe detailed clinical and pathologic findings along with the literature review. We focus on the differential diagnosis between DRESS lymphadenopathy and angioimmunoblastic T-cell lymphoma (AITL). RESULTS.­: There were 4 men and 1 woman with a mean age of 41 years (range, 23-59 years). One patient (20%) died. Three lymph node biopsy specimens showed a pattern reminiscent of AITL (AITL-like pattern) and 2 cases showed necrotizing lymphadenitis (Kikuchi-like pattern), associated with vasculitis in 1 case. The AITL-like morphology of DRESS-related lymphadenopathy may be difficult to distinguish from genuine AITL. The clinical information is important for differential diagnosis, including history of drug exposure, age, and the rarity or absence of AITL-associated manifestations such as hemolytic anemia and hypergammaglobulinemia. Molecular analysis of the T-cell receptor genes is helpful, typically revealing a polyclonal pattern in DRESS-related lymphadenopathy. CONCLUSIONS.­: In the literature, 4 histologic patterns of DRESS lymphadenopathy have been described: reactive lymphoid hyperplasia, necrotizing lymphadenitis, Hodgkin lymphoma-like, and AITL-like. These patterns, particularly those that resemble lymphoma, highlight the importance of correct diagnosis to avoid unnecessary therapies.

ABSTRACT

BACKGROUND: Periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA) syndrome is the most common cause of periodic fever in childhood. This study aimed to investigate sleep patterns and possible factors that are associated with sleep disturbances among children with PFAPA syndrome. METHODS: Sixty-two patients with PFAPA and 68 age and sex matched healthy controls were enrolled in the study. Patients who had an attack during the former 2 weeks were not included. Demographic and anthropometric data, duration of fever episodes, laboratory results, and clinical manifestations of patients were recorded. The Children`s Sleep Habits Questionnaire was administered. RESULTS: The total sleep scores of patients with PFAPA were significantly higher than the control group (49.6 ± 10.7 vs. 38.3 ± 7.5, p = 0.002 ). Children with PFAPA had significantly higher scores regarding sleep-onset delay, sleep anxiety and night wakening (p=0.003, p=0.007, and p=0.014, respectively). Total sleep durations were similar between children with PFAPA and the control group. There was a significant positive correlation between the total sleep score and disease duration (r=0.425, p=0.002). Also there was a significant positive correlation between disease duration and sleep onset delay (r=0.561, p < 0.001) and night wakening (r=0.327, p=0.003). CONCLUSION: This study showed for the first time that patients with PFAPA have significantly disturbed sleep when compared to otherwise normal children. This study emphasized the need to assess sleep problems in children with PFAPA.

ABSTRACT

BACKGROUND/OBJECTIVE: Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome is a polygenic disease with unknown etiology. In this retrospective cohort study, we aimed to evaluate the risk factors for the resolution of PFAPA syndrome within 4 years after the onset. METHODS: In total, 466 patients with PFAPA syndrome that are being followed up our department were included into the study. Between May 2020 and September 2020, medical charts of the patients were reviewed retrospectively. RESULTS: The median age of the patients at the time of the study and at disease onset were 8.6 (2.9-20.5; IQR 6.9-10.6) years and 18 (1-84; IQR 11-31) months. On univariate analysis age at disease onset (p = 0.003), positive family history of PFAPA syndrome (p = 0.04), absence of myalgia (p = 0.04), and absence of headache (p = 0.003) were all associated with the resolution of PFAPA syndrome within 4 years after the onset. Multivariate logistic regression analysis revealed that age at disease onset (OR 1.04, 95% CI 1.01-1.07, p = 0.002), positive family history of PFAPA syndrome (OR 2.69, 95% CI 1.12-6.48, p = 0.02), and absence of headache (OR 0.2, 95% CI 0.05-0.74, p = 0.01) were independent risk factors for the resolution of PFAPA syndrome within 4 years after the onset. CONCLUSION: We report later age of disease onset, positive family history of PFAPA syndrome, and absence of headache as independent risk factors for resolution of PFAPA syndrome within 4 years after the onset. KEY POINTS: • Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome is a multifactorial disease with unknown etiology. • Although, PFAPA syndrome usually resolves within 3-5 years after the disease onset, it can persist for years and even continue into adulthood. With our current knowledge, there is no clue to predict which patients will have a long disease course and which patients will not. • Later age of disease onset, positive family history of PFAPA syndrome and absence of headache as independent risk factors for resolution of PFAPA syndrome within 4 years after the onset.

ABSTRACT

BACKGROUND: Despite to PFAPA syndrome is considered a benign and self-limited condition in childhood its impact on patients and families can be remarkable in many cases. Currently, the therapeutic options for managing are non-specific and no consensus exists about the best treatment to use. Pidotimod has been suggested as a new potential treatment in PFAPA syndrome for its immunodulatory effects. We conducted a preliminary, prospective, controlled, open, cross-over trial to assess the efficacy and the safety of Pidotimod in the treatment of children with PFAPA syndrome. METHODS: 22 children with PFAPA syndrome were randomly allocated to treatment with pidotimod (with 2 vials of 400 mg daily) in combination with betamethasone 0.5-1 mg on need, based on parents/caregivers' decision (group A) or betamethasone 0.5-1 mg on need, based on parents/caregivers' decision (group B). Each treatment period was for 3 months (Phase 1), after that patients were switched to the other arm for other 3 months (Phase 2). Efficacy was expressed in terms of number of episodes of fever, pharyngitis, or aphthous stomatitis, as well as the additional use of betamethasone on need. Safety and tolerability of the Pidotimod were evaluated on the basis of the number and type of adverse events (AEs) recorded during the treatment. RESULTS: Patients receiving Pidotimod and use betametasone showed a significant decrease in frequency of fevers (p = 0.002); number of episodes of pharyngitis (p = 0.049); aphthous stomatitis (p = 0.036) as well as the betamethasone use on need (p = 0.007). Overall, 19/22 (86.4%) showed benefits from Pidotimod administration. The safety profile of Pidotimod was excellent as no serious adverse events have been reported in the treated groups. CONCLUSIONS: We firstly showed that high dosage of Pidotimod could be an effective and safe to reduce the PFAPA attacks in children.
