Vasculitic rash and cerebral emboli in an adolescent with left atrial myxoma.

A previously healthy woman in late adolescence presented to the emergency department with stroke-like symptoms following a two-month history of bilateral foot pain and oedema, accompanied by a macular rash and progressive lower extremity weakness. On further investigation, she was found to have multiple cerebral emboli and a left atrial myxoma fixed to the interatrial septum. The patient subsequently underwent urgent surgical excision of the myxoma. On follow-up, her cutaneous and neurological symptoms were significantly improved. This case suggests that, in the presence of a vasculitic rash without evident or obvious cause, cardiac myxoma should be included in the differential diagnosis.

Epilepsia Partialis Continua as a Sequelae of Measles Infection in Children With Hematolymphoid Malignancies.

PURPOSE: To share our clinical experience with the diagnosis and management of children with hematolymphoid malignancies presenting with epilepsia partialis continua (EPC) as a sequelae of measles infection. MATERIALS AND METHODS: In December 2022, a series of children in our hemato-oncology unit presented with focal status epilepticus with no conclusive evidence pointing toward any underlying etiology. One such child had a typical measles rash a few weeks before the onset of this focal status epilepticus. After a series of cases with a similar presentation, a clinical pattern suspicious for measles became evident. cerebrospinal fluid polymerase chain reaction was positive for measles virus with measles immunoglobin M detected in the serum. This led to the diagnosis of measles inclusion-body encephalitis in a series of children who presented with EPC over a period of 3 months. EPC is a rare manifestation of measles that is seen only in immunocompromised patients. RESULTS: Among the 18 children reported in this series, only 10 had a history of rashes. The rash was mostly transient and elicited only on retrospective history taking. Five of the 18 children who did not lose consciousness during the prolonged seizure episode survived the disease but had residual neurologic sequelae. Among the 18 children, two were unimmunized and immunization status could not be confirmed in three other children. CONCLUSION: This case series highlights the threats posed by measles infection in children with cancer who are immunosuppressed because of the underlying disease and ongoing chemotherapy. Loss of herd immunity because of declining measles immunization rates secondary to vaccine hesitancy and COVID-19 lockdown pose a greater risk of measles infection and its complications for patients with deficient immune systems.

Finger nodules with a papulovesicular hands and feet eruption: a complicated human Orf virus infection.

BACKGROUND: Orf virus (ORFV) is the pathogen responsible for Orf, a zoonotic viral infection that can be spread to humans from sheep and goats. Here, we present a case of human Orf complicated by an immune-related reaction, to raise awareness of this under-recognized disease avoiding unnecessary investigations and overtreatment. CASE REPORT: A 51-year-old woman with no previous medical history presented with a one-week history of three asymptomatic swelling nodules with a grey necrotic center and red outer halo on her index finger. At physical examination there was also a pruritic papulovesicular eruption on her hands and feet. She reported a recent contact with a goat which had a similar nodular lesion in its mouth. A biopsy of the lesions was performed and a diagnosis of Orf complicated by widespread erythema multiforme was made based on the clinical and histopathological features. The lesions spontaneously resolved within the next 2 weeks. CONCLUSIONS: Orf is not very prevalent in our region, so we performed a biopsy of the lesion to guide us toward a diagnosis. However, we should remember that the diagnosis of ecthyma relies on clinical evaluation and epidemiological criteria.

Amoxicillin Induced Fever, Rash, and Catatonia - A Case Study.

INTRODUCTION: Adverse drug reactions (ADR) are defined as any harmful or unpleasant events or injuries resulting from the use of any particular drug. Among those antibiotics that cause adverse reactions, amoxicillin is one of them. Catatonia and vasculitic rash are its rare adverse effects. CASE PRESENTATION: A 23-year-old postpartum female, with a history of taking empirical Amoxiclav (amoxicillin-clavulanic acid 625 mg) injection and oral tablets for episiotomy wound, presented with altered sensorium and fever followed by maculopapular rash. On examination, she had generalized rigidity with waxy flexibility that improved by lorazepam challenge and was diagnosed as catatonia. On evaluation, amoxicillin was found to be precipitating catatonia in this patient. CONCLUSION: Since the diagnosis of catatonia is often missed, any cases with clinical presentation of fever, rash, altered sensorium, and generalized rigidity should also be suspected for druginduced ADR and the precipitating factor should be searched for.

Successful complementary therapy with traditional Chinese medicine in a patient with Qi and Jin deficiency symptoms from adult-onset Still's disease: A case report.

BACKGROUND: Adult-onset Still's disease (AOSD) is a rare yet well-documented polygenic and systemic autoinflammatory disease characterized by recurrent spiking fever, transient skin rash, arthralgia, and sore throat. Traditional Chinese medicine (TCM) holds a significant role in complementary and alternative medicine. This study presents a unique case of a female AOSD patient with concurrent Qi and fluid deficiency syndrome who received combined treatment with formulated Zhu Ye Shi Gao Decoction (ZYSGD). CASE PRESENTATION: In this case, a 28-year-old female patient presented with a 15-day history of fever and skin rash accompanied by sore throat, fatigue, myalgia, and arthralgia. Additionally, leucocytosis, aminotransferase abnormalities, and elevated inflammatory factor levels were observed. Infectious diseases, solid tumors, and hematological disorders were all ruled out. Anti-infective treatments proved ineffective, leading to the final diagnosis of AOSD. Glucocorticoid therapy provided only partial relief. Consequently, formulated ZYSGD and hepatoprotective drugs were added to the glucocorticoid treatment. Subsequently, the patient's symptoms and inflammatory biomarkers showed improvement. After discharge, the patient's condition remained stable while continuing the formulated ZYSGD in combination with 4 mg of Medrolol (qd) during a 10-month follow-up period. CONCLUSION: This case report suggests that formulated ZYSGD could be a viable option for complementary and alternative therapy for late-stage AOSD, especially in cases involving both Qi and body fluid imbalances.

Epidemiology, clinical profiles, and prognostic value of COVID-19-related cutaneous manifestations in African populations: a rapid narrative review.

BACKGROUND: Skin manifestations' true prognostic value, and clinical and epidemiological pictures in SARS-CoV-2 infection in African populations are poorly described and understudied. More familiarity with COVID-19 cutaneous manifestations may aid in early clinical diagnosis or guide prognosis. METHODS: In this literature review, we looked for potential studies published from December 2019 to March 2023 on COVID-19 cutaneous lesions in African populations. Our key questions were focused on the prognostic values of cutaneous manifestations related to COVID-19. RESULTS: Our findings show that cutaneous manifestations of COVID-19 vary by country and severity of COVID-19, primarily multisystem inflammatory syndrome (MIS). Significant differences were also found between various dermatological lesions, primarily MIS, erythema multiforme-like, livedoid, vesicular, or varicella-like rashes, urticarial, maculopapular or morbilliform rashes, and chilblain-like or pernio-like rashes. There were 47.5% (115/242) of MIS cases reported in nine published African studies. Our findings also revealed that MIS may be diagnosed in 2-7 days due to early onset rash. Advanced age, obesity, diabetes, cardiovascular disease, HIV, tuberculosis, asthma, atopic disease, underweight, malnutrition, and malignancy were found to be associated with COVID-19 cutaneous manifestations in African populations. CONCLUSIONS: COVID-19-related skin manifestations in African populations are important as a driving force in COVID-19 prognosis.

Foamy Macrophages in a Case of Mononucleosis With Amoxicillin-Induced Rash, Hyperlipidemia, and Hemophagocytic Lymphohistiocytosis.

ABSTRACT: A 38-year-old man presented with fever, cough, and jaundice. Four days before, he had started taking amoxicillin/clavulanic acid. He subsequently developed a morbilliform rash, and, according to clinical features and blood analyses, a diagnosis of mononucleosis with Epstein-Barr virus-associated antibiotic-induced exanthema and secondary hemophagocytic lymphohistiocytosis was made. A skin biopsy revealed a superficial perivascular lymphohistiocytic infiltrate with interface dermatitis and many foamy macrophages in the papillary dermis and around the vessels of the superficial dermal plexus. A blood lipid test uncovered marked hypercholesterolemia and hypertriglyceridemia. After treatment with dexamethasone and immunoglobulin, the skin rash, liver function, and lipid profile progressively improved. Xanthomatous cells have been observed in skin biopsies of acute graft-versus-host disease with liver involvement, and these cells have been suggested to represent a clue to the presence of hepatic disease. In our case, underlying cholestatic hepatopathy with hyperlipidemia was present. We believe that the incidental finding of foamy cells in graft-versus-host disease cases and in our case are likely related to the presence of severe liver disease with cholestatic hepatopathy and secondary hyperlipidemia in different background conditions.

Gender differences in patients with anti-MDA5-positive dermatomyositis: a cohort study of 251 cases.

OBJECTIVE: To investigate the impact of sex differences on the clinical characteristics and prognosis of patients with anti-melanoma differentiation-associated gene 5-positive dermatomyositis (MDA5+ DM). METHODS: We retrospectively analyzed a cohort of 251 patients with MDA5+ DM, including 71 in the male group and 180 in the female group. A multivariate logistic regression model was built to analyze independent risk factors for RPILD in each group. An ROC curve was drawn to evaluate the predictive value of independent risk factors. Kaplan‒Meier analysis was used to compare the cumulative survival rates, while the log-rank test was used to test for significant differences between the two groups. RESULTS: Patients in the male group had a significantly higher prevalence of heliotrope rash, V sign, severe interstitial lung disease (ILD), and rapidly progressive interstitial lung disease (RPILD) than those in the female group. Anti-Ro52 positivity, high CRP level and short disease were identified as independent risk factors for RPILD in both male and female groups by multivariate logistic regression analysis. The mortality rates of males and females were 33.8% and 22.0%, respectively, and the survival time of patients in the male group was shorter than that in the female group. CONCLUSION: Male patients with MDA5+ DM exhibit an increased risk of RPILD, elevated mortality rates and reduced overall survival time compared to their female counterparts, and anti-Ro52 positivity may be an unfavorable prognostic factor for these patients. Key Points • The prevalence of solar rash, V sign, severe interstitial lung disease (ILD) and rapidly progressive interstitial lung disease (RPILD) in anti-MDA5-positive female patients was significantly lower than that in male patients. • Positive Anti-Ro52, high CRP level, and short course of disease were independent risk factors for RPILD in both men and women. • Female patients exhibited a lower mortality rate than male patients (22.0% vs 33.8%) and demonstrated longer survival time.

[Analysis of 9 cases of drug induced hypersensitivity syndrome related hemophagocytic lymphohistiocytosis].

Objective: To analyze the clinical features,treatment and prognosis of drug induced hypersensitivity syndrome related hemophagocytic lymphohistiocytosis (DIHS-HLH). Methods: This was a retrospective case study. Clinical characteristics, laboratory results, treatment and prognosis of 9 patients diagnosed with DIHS-HLH in Beijing Children's hospital between January 2020 and December 2022 were summarized. Kaplan-Meier survival analysis was used to calculate the overall survival rate. Results: Among all 9 cases, there were 6 males and 3 females, with the age ranged from 0.8 to 3.1 years. All patients had fever, rash, hepatomegaly and multiple lymph node enlargement. Other manifestations included splenomegaly (4 cases), pulmonary imaging abnormalities (6 cases), central nervous system symptoms (3 cases), and watery diarrhea (3 cases). Most patients showed high levels of soluble-CD25 (8 cases), hepatic dysfunction (7 cases) and hyperferritinemia (7 cases). Other laboratory abnormalities included hemophagocytosis in bone marrow (5 cases), hypofibrinogenemia (3 cases) and hypertriglyceridemia (2 cases). Ascending levels of interleukin (IL) 5, IL-8 and interferon-γ (IFN-γ) were detected in more than 6 patients. All patients received high dose intravenous immunoglobulin, corticosteroid and ruxolitinib, among which 4 patients were also treated with high dose methylprednisolone, 2 patients with etoposide and 2 patients with cyclosporin A. After following up for 0.2-38.6 months, 7 patients survived, and the 1-year overall survival rate was (78±14)%. Two patients who had no response to high dose immunoglobulin, methylprednisolone 2 mg/(kg·d) and ruxolitinib died. Watery diarrhea, increased levels of IL-5 and IL-8 and decreased IgM were more frequently in patients who did not survive. Conclusions: For children with fever, rash and a suspicious medication history, when complicated with hepatomegaly, impaired liver function and high levels of IL-5 and IL-8, DIHS-HLH should be considered. Once diagnosed with DIHS-HLH, suspicious drugs should be stopped immediately, and high dose intravenous immunoglobulin, corticosteroid and ruxolitinib could be used to control disease.

A case report of dermatomyositis mimicking myasthenia gravis.

RATIONALE: Patients who have myasthenia gravis or dermatomyositis show clinical signs of muscular weakening. Ocular muscle involvement is uncommon, and symmetrical proximal limb weakness is the typical presentation of dermatomyositis. However, the earliest and most noticeable sign in those with myasthenia gravis is extraocular muscular paralysis. Dermatomyositis is frequently complicated by malignancy, and the common malignancies associated with dermatomyositis vary by region and ethnicity, while thymoma is relatively rare. About 10% to 15% of people with myasthenia gravis have thymoma, which is involved in the etiology of the disease. PATIENT CONCERNS: A 68-year-old female presented with ocular muscle weakness for 10 days that manifested as bilateral blepharoptosis with the phenomenon of "light in the morning and heavy in the evening." Imaging examination showed anterior mediastinal thymic tumor with metastasis. DIAGNOSES: After a thorough physical examination, we discovered bilateral upper limbs with grade IV muscle strength and the typical rash of dermatomyositis. In combination with elevated serum kinase levels and electromyography suggesting myogenic damage, the patient was finally diagnosed as dermatomyositis with multiple metastases of thymoma. INTERVENTIONS: The patient received oral hydroxychloroquine sulfate, topical corticosteroids, and tacrolimus ointment, but these did not work very well. Subsequently, the patient underwent surgery combined with radiotherapy for the thymoma. OUTCOMES: Muscle weakness in the patient improved after effective treatment of tumor, and the rash mostly disappeared. CONCLUSION: Ocular muscle weakness and thymoma are more common in myasthenia gravis, but we cannot ignore the possibility of dermatomyositis. To further establish the diagnosis, a thorough physical examination and laboratory findings are required. Further tumor screening should be performed for patients with dermatomyositis. Early detection and management of possible tumors are essential to the treatment of dermatomyositis linked to malignancies.

Atypical cutaneous presentation of AOSD with persistent itchy urticaria: A case report.

RATIONALE: Adult-onset Still's disease (AOSD) is a rare multisystem disorder considered a complex autoinflammatory syndrome. The clinical and biological features of AOSD typically include a high fever with arthritic symptoms, evanescent skin rash, sore throat, striking neutrophilic leukocytosis, hyperferritinemia, and abnormal liver function. The typical rash and fever are important diagnostic clues for AOSD. Here, we report a case of atypical rash manifesting as persistent itchy urticaria. PATIENT CONCERNS: A 57-year-old female presented with a 6-day history of fever. During her hospital stay, she progressively developed rashes that were not associated with fever, primarily distributed on her back and the distal extremities, and associated with pronounced itching. The rash was initially suspected to be urticaria; however, the patient exhibited a poor response to antihistamines. After malignancies and other rheumatic diseases were excluded, the diagnosis leaned towards AOSD based on diagnostic criteria. The patient's fever was well controlled with the initiation of glucocorticoids, and no further rashes were observed. DIAGNOSES: Although the patient exhibited atypical rashes, after ruling out malignancies and other rheumatic diseases, she met 2 major and 3 minor criteria. Based on Yamaguchi's criteria, the patient was diagnosed with AOSD. INTERVENTIONS: Initially, the patient was administered an intravenous infusion of methylprednisolone at 40 mg once daily. This was later transitioned to oral administration with gradual dose reduction. OUTCOMES: Follow-up at 1 year showed no recurrence of the rash, with a stable condition and no relapse. LESSONS: This case provides valuable insights for the early diagnosis of AOSD, emphasizing the importance of considering this diagnosis even when presenting with atypical skin rash.

Sintilimab-induced erythema multiforme drug eruption in the treatment of sigmoid colon cancer: A case report and literature review.

RATIONALE: Dermatologic toxicity has been reported as the most common immune-related side effect of programmed cell death 1 inhibitors. Previous reports related to Sintilimab include rash, pruritus, vitiligo, Stevens-Johnson syndrome, toxic epidermal necrolysis, and so on. PATIENT CONCERNS: A 66-year-old man was treated with Sintilimab as monotherapy for sigmoid colon cancer. After the second prescription, he developed a more severe and widespread rash. DIAGNOSES: The diagnose of erythema multiforme drug eruption induced by Sintilimab was considered. INTERVENTIONS: The patient received intravenous and oral methylprednisolone, routine antihistamines and topical gluccorticoids. OUTCOMES: The patient's symptoms were gradually relieved during hospitalization and was discharged following resolution of symptoms. He refused to continue using Sintilimab. LESSONS: This is the first reported case of Sintilimab-induced erythema multiforme drug eruption. It is advisable to inform patients of potential dermatologic toxicity that may occur after using immune checkpoint inhibitors, so that we may prevent the further development of it and avoid the discontinuation of immune checkpoint inhibitors.

Clinical features of dermatomyositis patients with anti-TIF1 antibodies: A case based comprehensive review.

BACKGROUND AND OBJECTIVES: Dermatomyositis is chronic autoimmune disease primarily affecting skin and muscles. Antibodies are key players of pathogenesis and are in strong correlation with distinct clinical phenotypes. We present a case and a comprehensive review of the literature on dermatomyositis patients with Anti TIF1 antibodies. METHODS: PubMed and Web of Science databases were reviewed. 166 articles were identified; 95 of them were evaluated; 79 of them included to the study. 45 of the included articles were case reports 9 were case series and 25 were research articles. In total 1065 patients were identified but number of patients with available information for different clinical features varied. RESULTS: 69.6% of the patients with Anti TIF1-γ were female. Prevalence of malignancy was 42.6% among patients with Anti TIF1-γ. Muscle weakness (83%), Gottron sign (82.2%), heliotrope rash (73.7%), nailfold capillary changes (67.7%), dysphagia (38.4%), and joint involvement (31.1%) were the most common clinical features seen in patients with Anti TIF1-γ. Interstitial lung disease (ILD) was reported among 8.7% of patients with Anti TIF1-γ. Advanced age, male gender, dysphagia, and V-neck rash were significant risk factors for malignancy, whereas juvenile age, ILD, TIF1-ß antibodies and joint involvement were associated with a decreased risk for malignancy. Advanced age, malignancy, dysphagia, and muscle involvement were associated with an increased risk for mortality. CONCLUSIONS: Patients with advanced age, male gender, dysphagia, and V-neck rash require strict cancer screening. Patients with advanced age, malignancy, dysphagia, and muscle involvement have poor prognosis and should receive aggressive treatment.

Chlamydia psittaci -Induced Reactive Infectious Mucocutaneous Eruption With Ocular Involvement.

INTRODUCTION: This report highlights a postinfectious mucocutaneous inflammatory response involving the ocular surface and adnexa after Chlamydophila psittaci exposure. CASE DESCRIPTION: A 35-year-old man presented after a prodrome of upper respiratory symptoms with rash and mucocutaneous blistering involving the ocular and oral mucosa, causing pseudomembranous conjunctivitis and corneal epithelial defects. Extensive inflammatory and infectious workup suggested recent C. psittaci infection. The patient was treated with doxycycline and supportive therapy, whereas the ocular surface was treated with lubrication and prophylactic antibiotics. In follow-up, he has retained excellent visual acuity but required scleral contact lenses to control ocular surface symptoms because of fibrotic changes of the marginal conjunctiva. DISCUSSION: Such blistering inflammation has most commonly been described after pediatric respiratory infections because of Mycoplasma pneumoniae with additional instances related to Chlamydia pneumoniae , Epstein-Barr virus, influenza B, and other stimuli . To the best of our knowledge, this is the first reported case of C. psittaci- induced reactive infectious mucocutaneous eruption (RIME). RIME is a rare parainfectious inflammatory condition with sequelae frequently involving the periocular mucosa. Although systemic and nonocular adverse outcomes in this condition tend to be self-limited, the impact on the ocular surface may be severe, and the consequences to vision may be ongoing, especially if not treated aggressively at the outset.

Gray zone in the spectrum of autoinflammatory diseases: familial Mediterranean fever accompanying periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome: single-center experience.

Despite the advanced knowledge concerning autoinflammatory diseases (AID), more data regarding the optimal treatment options and outcomes of the children who met the criteria of more than one AID are required. This study aimed to describe the demographic and clinical characteristics of children from familial Mediterranean fever (FMF)-endemic countries who meet both the FMF and the periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome criteria. Moreover, we aimed to measure the response rates to colchicine and tonsillectomy and evaluate the factors affecting the colchicine response in these patients. The study was conducted at pediatric rheumatology tertiary centre. A total of 131 patients (58 females; 73 males) who met both the modified Marshall and pediatric FMF criteria were included. The median age at onset was 18 months (1-77 months), and the mean age at diagnosis was 47 ± 21.88 months. The median interval between episodes was 21 (7-90) days. The median disease duration was 46 (6-128) months. Consanguineous marriage was detected in 17 (13%) of the patients. The most common clinical finding was fever (100%), followed by exudative pharyngitis (88.5%), abdominal pain (86.3%), arthralgia (61.8%), stomatitis (51.1%), adenitis (42%), myalgia (28.7%), chest pain (16%), maculopapular rash (12.2%), arthritis (8.4%), and erysipelas-like rash (4.6%). MEFV gene variants were identified in 106 (80.9%) patients. The most common variants were M694V heterozygous (29%). We found that patients with tonsillopharyngitis, aphthous stomatitis, and PFAPA family history were more likely to be colchicine-resistant and tonsillectomy responsive, while those with exon 10 MEFV gene mutations were more prone to have a favorable response to colchicine.     Conclusion: PFAPA syndrome patients with exon 10 MEFV gene mutation, showing typical FMF symptoms, should be treated with colchicine, even after tonsillectomy. In multivariate analysis, PFAPA family history and lack of exon 10 MEFV gene mutations were independent risk factors for colchicine resistance. Thus, tonsillectomy may be recommended as a possible treatment option for these patients. It has yet to be clarified when colchicine treatment will be discontinued in patients whose attacks ceased after tonsillectomy that was performed due to colchicine unresponsiveness. What is Known: • A certain number of patients with periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome concomitantly fulfill the familial Mediterranean fever (FMF) criteria. • While colchicine is proposed as a first treatment choice in familial Mediterranean fever (FMF), corticosteroids are recommended as a first-line treatment in PFAPA syndrome patients. What is New: • In patients with concomitant PFAPA syndrome and FMF, PFAPA family history and lack of exon 10 MEFV gene mutation are predictive factors of colchicine resistance. • The presence of exon 10 MEFV gene mutations in patients with concomitant FMF and PFAPA syndrome has a favourable effect on response to colchicine treatment.

Pathogenic variants in the NLRP3 LRR domain at position 861 are responsible for a boost-dependent atypical CAPS phenotype.

BACKGROUND: Cryopyrin-associated periodic syndrome (CAPS) is associated with NLRP3 pathogenic variants, mostly located in the NACHT (neuronal apoptosis inhibitor protein, MHC class 2 transcription activator, incompatibility locus protein from Podospora anserina, telomerase-associated protein) domain. Cold-induced urticarial rash is among the main clinical features. However, this study identified a series of 14 patients with pathogenic variants of the Y861 residue (p.Tyr861) of the LRR domain of NLRP3 and minimal prevalence of cold-induced urticarial rash. OBJECTIVES: This study aimed to address a possible genotype/phenotype correlation for patients with CAPS and to investigate at the cellular levels the impact of the Y861C substitution (p.Tyr861Cys) on NLRP3 activation. METHODS: Clinical features of 14 patients with CAPS and heterozygous substitution at position 861 in the LRR domain of NLRP3 were compared to clinical features of 48 patients with CAPS and pathogenic variants outside the LRR domain of NLRP3. IL-1ß secretion by PBMCs and purified monocytes from patients and healthy donors was evaluated following LPS and monosodium urate crystal stimulation. RESULTS: Patients with substitution at position 861 of NLRP3 demonstrated a higher prevalence of sensorineural hearing loss while being less prone to skin urticarial. In contrast to patients with classical CAPS, cells from patients with a pathogenic variant at position 861 required an activation signal to secrete IL-1ß but produced more IL-1ß during the early and late phase of secretion than cells from healthy donors. CONCLUSIONS: Pathogenic variants of Y861 of NLRP3 drive a boost-dependent oversecretion of IL-1ß associated with an atypical CAPS phenotype.

Risk factors and prognosis of interstitial lung disease for primary Sjögren syndrome patients: A retrospective case‒control study.

OBJECTIVE: To determine the prevalence, clinical features, risk factors, and prognosis of interstitial lung disease (ILD) in patients with primary Sjogren's syndrome (pSS). METHODS: Data from 274 pSS patients from August 2013 to August 2022 were reviewed. The clinical features of pSS with ILD were revealed. Logistic regression was used to determine risk factors for ILD in pSS patients. Survival analysis and Cox regression were used to analyse the prognosis and prognostic factors of pSS patients. RESULTS: In pSS patients, the prevalence of ILD was 22.3% (61/274). The pSS patients with ILD were characterized by a late onset and long disease course, with a nonspecific interstitial pneumonia (NSIP) pattern as the predominant high-resolution computed tomography (HRCT) finding. Logistic regression results indicated that an age over 50 years old (OR 4.786, 95% CI 1.602-14.299; P = 0.005), purpuric rash (OR 4.695, 95% CI 1.537-14.339; P = 0.007), AMA-M2 antibody positivity (OR 2.582, 95% CI 1.166-5.722; P = 0.019), and diabetes (OR 2.514, 95% CI 1.025-6.167; P = 0.044) were risk factors for ILD in pSS patients. Cox regression results showed that advanced age (HR 1.240, 95% CI 1.088-1.413; P = 0.001) and cancer history (HR 8.411, 95% CI 1.771-39.934; P = 0.007) were risk factors for pSS patient survival. CONCLUSION: This study showed that pSS patients with ILD tended to have a late onset and long course of pSS. An age over 50 years, purpuric rash, AMA-M2 antibody positivity, and diabetes were risk factors for ILD in pSS patients. Advanced age and cancer history were prognostic factors in pSS patients. Key Points • This study showed that pSS patients with ILD tended to have a late-onset and lengthy course of pSS, with the NSIP pattern as the predominant lung image. • The risk factors for ILD in pSS patients determined in this study were an age over 50 years, purpuric rash, AMA-M2 antibody positivity, and diabetes. • The prognostic risk factors for pSS patients were advanced age and cancer history.

Diagnosis and treatment of varicella-zoster virus infection with herpetic visceral neuralgia without rash: A case report.

RATIONALE: Herpes zoster (HZ) is an infection caused by the varicella-zoster virus reactivation, often leading to peripheral nervous system infection and pain. This case report aimed to present 2 patients with damaged sensory nerves originating from the visceral neurons of the lateral horn of the spinal cord. PATIENT CONCERNS: Two patients presented intractable, severe lower back pain and abdominal pain, but without rash or herpes. A female patient was admitted 2 months after symptom onset. She was presented with paroxysmal, acupuncture-like pain in the right upper quadrant and around the umbilicus without apparent incentives. A male patient was presented with recurrent episodes of paroxysmal and spastic colic in the left waist and left middle abdomen for 3 days. Abdominal examination showed no tumors or organic lesions in their intra-abdominal tissues or organs. DIAGNOSES: After excluding organic lesions on the waist and in abdominal organs, patients were diagnosed with herpetic visceral neuralgia without rash. INTERVENTION: The treatment for herpes zoster neuralgia or postherpetic neuralgia was applied for 3 to 4 weeks. OUTCOME: Antibacterial and anti-inflammatory analgesics were not effective in either patient. The therapeutic effects of herpes zoster neuralgia or postherpetic neuralgia treatment were satisfactory. LESSONS: Herpetic visceral neuralgia can be easily misdiagnosed due to the absence of a rash or herpes, resulting in delayed treatment. When patients have severe, intractable pain but no rash or herpes, and the biochemical and imaging examinations are normal, the treatment method for HZ neuralgia can be used. If the treatment is effective, HZ neuralgia is diagnosed. If not, shingles neuralgia can be ruled out. Further investigations are required to elucidate the mechanisms of pathophysiological changes in varicella-zoster virus-induced peripheral HZ neuralgia or visceral neuralgia without herpes.
