Investigations of these autoantibodies play a major role in the management of several autoimmune diseases. The objective of this study was to describe the profile of anti-ENA antibodies according to the clinical symptoms of mixed CTDs in Conakry teaching Hospital. We performed a cross-sectional study during six months. A total of 20 patients was recruited and we measured antibodies using the ELISA technique. The mean age of our patients was 36.5 years, with a predominance of females. Cutaneous and rheumatological signs were the main clinical manifestations. SLP was the most frequent CTDs;the threshold of ENA antibodies positivity was higher in scleroderma with and SLP. Anti-ENA identification reveals the frequency of anti-SSA (83.33%), anti-U1RNP (66.66%) and anti-histone (50%) antibodies. Antinuclear antibodies (ANA) react with various components of the cell nucleus. Their detection is of major interest in the diagnosis of CTDs. Our results highlight the importance of determining the specificity of these antibodies to guide differential diagnosis.展开更多

Methods AECAs in sera of 39 CTD patients with PAH,22 CTD patients without PAH,and 10 healthy donors as controls were detected with Western blotting. The prevalence of different AECAs in different groups was compared and its correlation with clinical manifestations was also investigated. Results The prevalence of AECAs was 82.1% in CTD patients with PAH,72.7% in CTD patients without PAH,and 20.0% in healthy donors. Anti-22 kD AECA was only detected in CTD patients with PAH (15.4%). Anti-75 kD AECA was more frequently detected in CTD patients with PAH than in those without PAH (51.3% vs. 22.7%,P<0.05). In CTD patients with PAH,anti-75 kD AECA was more frequently detected in those with Raynaud’s phenomenon or with positive anti-RNP antibody. Conclusion AECAs could be frequently detected in CTD patients with or without PAH,while anti-22 kD and anti-75 kD AECA might be specific in CTD patients with PAH.展开更多

A mutation in the GLA gene leads to a loss of activity of alpha-galactosidase A. Some drugs,such as hydroxychloroquine, can cause pathological changes similar to those usually seen in Fabry disease.CASE SUMMARY We report the case of a 41-year-old female patient who was diagnosed with undifferentiated connective tissue disease in 2008. Hydroxychloroquine treatment started 2 years ago, and proteinuria and hematuria increased. Renal biopsy demonstrated renal phospholipidosis. Zebra bodies and myelin figures were found by renal electron microscopy and were initially thought to be indicators of Fabry disease. A genetic analysis of the patient and her family members did not reveal mutations in the GLA gene, supporting a diagnosis of hydroxychloroquine-induced renal phospholipidosis.CONCLUSION This report reveals one of the adverse effects of hydroxychloroquine. We should pay more attention to hydroxychloroquine-induced renal phospholipidosis.展开更多

We report, here, a case of a middle-aged woman with UCTD-related hepatic injury, including its case history, clinical manifestations, laboratory findings, treatment and its short-term effect. The patient was admitted to the hospital with symptoms of fatigue, anorexia, low-grade fever and skin rashes. She had a past history of left knee joint replacement. Laboratory tests showed elevated levels of serum transaminase, IgG and globulin, accelerated erythrocyte sedimentation rate, eosinophilia and a high titer of antinuclear antibodies (1:320). Imaging studies showed interstitial pneumonitis and hydropericardium. Liver biopsy showed the features which were consistent with those of connective tissue diseases-related polyangitis. After treatment with a low-dose of oral prednisone, both symptoms and laboratory findings were significantly improved. UCTD-related hepatic injury should be considered in the differential diagnosis of connective tissue diseases with abnormal liver function tests. Low- dose prednisone may effectively improve both symptoms and laboratory tests.展开更多

However, while the prevalence of some autoantibodies increases with age, the incidence of connective tissue diseases decreases with age. This study aims to determine the clinical and paraclinical characteristics of connective tissue diseases in the elderly population. Materials and Methods: We conducted a retrospective and descriptive study, from March 2010 to March 2021, in the Internal Medicine Department of Aristide Le Dantec Hospital, including all the medical records of patients followed up for connective tissue disease and whose symptomatology began at an age greater than or equal to 65 years. Epidemiological, clinical, paraclinical, therapeutic and evolutionary data were collected from a pre-established survey form and then processed using SPSS software. Results: Overall, 22 cases were collected out of 275 seen on consultation. They involved 16 women and 6 men, aged between 65 and 85 years with a median of 70 years. The mean duration of the clinical picture was 15.7 months with extremes of 1 and 96 months. The clinical symptoms were joint pain in 21 patients associated with dry eye and mouth syndrome in seven cases and one patient underwent isolated dry eye and mouth syndrome. Joint involvement was deforming in 13 patients. Poor general condition was noted in 20 patients. Biology showed anemia in 14 patients, hyperleukocytosis (2 patients) and thrombocytosis (5 patients). The sedimentation rate (SR) was accelerated in 9 patients and the C-reactive protein (CRP) was positive in 12 patients. Immunology showed a positive Latex test (3 patients/6), Waaler-Rose reaction (8 patients/13), anti-cyclic citrullinated peptides (anti-CCP) antibodies (11 patients/11), anti-nuclear antibodies (2 patients/4). Anti-extractable nuclear antigens (anti-ENA) antibody testing in 4 patients showed positive anti-U1RNP (1 case), anti-SSA and anti-SSB (1 case). Plain X-Rays of the hands, wrists and feet showed destructive lesions in 16 patients. The diagnosis of rheumatoid arthritis (RA) was set in 21 patients, one of which was associated with Sjogren’s syndrome (SS) and one with primary Sjogren’s syndrome. Treatment was based on prednisone (21 cases), methotrexate (17 patients), and hydroxychloroquine (9 patients). The evolution was remarkable in 10 patients. Conclusion: Autoimmune diseases in the elderly are uncommon compared to the young adult population. In our study, we only found cases of rheumatoid arthritis and Sjogren’s syndrome. As the population ages, connective tissue diseases may be increasingly diagnosed.展开更多

Its distinctive feature and the basis for the diagnosis of MCTD is the presence of an antibody against the uridine-rich RNP of the cell nucleus (Anti-U1-RNP). It has been observed that intercurrent infections can trigger autoimmune diseases, however, the fact that viral infections—such as SARS-CoV-2—induce them is currently poorly understood. The present study raises the etiological role of the SARS-CoV-2 virus in the development of the disease. Authors describe the case of a 38-year-old patient in good general condition, who was diagnosed with mixed connective tissue disease three months after COVID-19 infection.展开更多

METHODS: Eight patients underwent inflatable penile prostheses and 15, testicular prostheses consented to the study. Their medical records were reviewed and a follow-up interview and physical and serological examinations were performed. RESULTS: In patients with penile prostheses, there was no abnormal antinuclear antibody (ANA) or IgM elevation. The serum levels of the rheumatoid factor (RF), C4, IgA and IgG were abnormal in one patient, and the levels of erythrocyte sedimentation rate (ESR) and C3, abnormal in two. Four had elevated IgE. In patients with testicular prostheses, there was no abnormal RF, ANA or IgM. The serum levels of ESR and IgA were abnormal in two, and three had abnormal C4, ten abnormal C3, and eleven decreased IgG. All had increased IgE. Men with penile prostheses had higher serum levels of IgG and IgM than those with testicular prostheses (P=0.001, P=0.016, respectively). The rates of abnormal values of IgE and IgG were higher in men with testicular prostheses than in men with penile prostheses (P=0.008, P=0.009, respectively). Physical examination was normal in all patients and nobody had documented symptoms pertinent to connective-tissue diseases. CONCLUSION: Our findings suggest that the risk of connective-tissue diseases is not higher in patients wearing prostheses as the ANA is negative and there is no apparent manifestation suggestive of connective-tissue diseases.展开更多

We evaluated risk factors for depression and anxiety in an autoimmune disease cohort compared with diabetic patients. Patients and Methods: We conducted an observational, cross-sectional, case-control survey comparing two groups: individuals with connective tissue disease (CTD) and diabetic controls who were followed within three Dakar University hospitals during the period from April to June 2023. Results: The sample comprised 106 participants, of whom 51 (48%) had CTD and 55 (52%) served as diabetic controls. In the CTD group, the majority had lupus (19) and rheumatoid arthritis (23). The CTD patients had a mean age of 41.0 years (SD 16.9), while the diabetic patients had a mean age of 55.9 years (SD 11.7), with a significant difference observed (p Conclusion: Compared to a chronic disease, devastating in Africa and evolving over the long term, autoimmune diseases are more strongly and more frequently associated with anxiety and depression. This is a factor to be taken into account in the holistic management of these patients.展开更多

Throughout the world, 287 cases of Rhupus have been described. We report two new observations of two patients who presented predominantly distal erosive polyarthritis with positive anti-Sm antibodies in one case and SmRNP in the other case. Observations: Case 1: 37 years old patient, with a recent diagnosis of pulmonary tuberculosis. She has since 8 months an inflammatory, bilaterally and symmetrical polyarthralgia without deformation or ankylosing synovitis, associated with malar erythema without other abnormalities. Immunological tests showed: positive Rheumatoid factor at 158 IU/ml, positive Anti-CCP at 550 IU/ml, and positivity of antinuclear at 1/1280 nuclear fluorescence with a strong presence of anti-Sm >8 IU/ml. The diagnosis of rhupus was concluded, without serious visceral involvement. Case 2: A 28-year-old patient, married with 3 children, with bilateral, symmetrical, deforming and chronic polyarthritis affecting large and small joints, which had been evolving for over 5 years without cutaneous abnormality associated. Paraclinical investigations showed: a biological inflammatory syndrome. Immunology was positive, with rheumatoid factors at 78 IU/ml, anti-CCP at 561 IU/ml, antinuclear antibodies at 1/1280 with positive anti-SmRNP and anti-SSA/Ro52, and a positive direct Coombs test. Joint ultrasound revealed tenosynovitis of the extensors and common flexors of the fingers, erosions and synovitis of multiple PPIs. The diagnosis of rhupus was based on the presence of 10 ACR criteria for RA and 8 ACR/EULAR 2019 criteria for SLE. Conclusion: Rheumatoid arthritis is a rare autoimmune disease combining features of both systemic lupus erythematosus and rheumatoid arthritis in the same patient, often sequentially. Despite a growing number of case reports and series, a consensus on the classification of SLE arthritis is still lacking, and diagnostic criteria for rhupus do not exist. These cases of rhupus must be recognized, as the vital and/or functional prognosis may be different from SLE alone or isolated RA.展开更多

Risk factors and clinical characteristics in these patients are not equivalent to those in traditional CAD patients. The objective of this study was to report short- and long-term clinical outcomes in a consecutive series of patients with CTD who underwent percutaneous coronary intervention （PC1） with stent implantation. Methods： The study group comprised 106 consecutive patients with CTD who underwent PCI in Beijing Friendship Hospital between January 2009 and June 2012. Medical records were analyzed retrospectively including clinical basic material, coronary angiogram data, and the incidence of major adverse cardiac events （MACEs） during the short- and long-term （median 3 years） follow-up. Results： Ninety-two of the patients （86.8%） had one or more traditional CAD risk lhctors. Multivessel disease was present in more than 2/3 of patients （73.6%）. Tbe left anterior descending coronary artery was the most commonly affected vessel （65. 1%）. Five bare-metal stents and 202 drug-eluting stents were implanted. After a median follow-up period of 36 months, thirteen patients （12.3%） died from cardiac causes, the rate of stent thrombosis was 9.4%, and the rate of target vessel revascularization （TVR） was 14.2%. Multivariate analysis revealed that hypertension （hazard ratio [HR] = 3.07, 95% confidence interval [CI]： 1.30-7.24, P = 0.041 ）, anterior myocardial infarction （HR - 2.77. 95% CI： 1.06-7.03, P = 0.04）, longer duration of steroid treatment （HR - 3.60, 95% CI： 1.43-9.08, P 0.032）, and C-reactive protein level 〉10 mg/L （HR 3.98, 95% CI： 1.19 12.56, P = 0.036） were independent predictors of MACEs. Conclusions： Patients with CTD and CAD may have severe coronary lesions. PCI in these patients tends to result in an increased rate of stent thrombosis and TVR during long-term follow-up, which may be influenced by traditional and nontraditional risk factors.展开更多

A colonoscopy revealed a giant brown fecaloma occupying the lumen of the colon and a colonic ulcer that was caused by the fecaloma. The surface of the fecaloma was hard, large and slippery, and fragmentation was not possible despite the use of various devices, including standard biopsy forceps, an injection needle, and a snare. However, jumbo forceps were able to shave the surface of the fecaloma and break it successfully by repeated biting for 6 h over 2 d. The ability of the jumbo forceps to collect large mucosal samples was also appropriate for achieving fragmentation of the giant fecaloma.展开更多

Their outcome is variable and has been little studied in Africa. We report the epidemiological, paraclinical and evolutionary characteristics of seven cases of indeterminate polyarthritis. Material and Method: From January 2012 to May 2021, we selected all the files of patients followed up for unclassified inflammatory rheumatism and in whom a precise diagnosis was retained during the course of the disease. The diagnosis of unclassified inflammatory rheumatism was retained after biological, immunological and radiological explorations without specificities. Our study took place in the Internal Medicine Department of Aristide Le Dantec Hospital (HALD). Results: Seven cases out of 274 consulted were collected. They consisted of seven women with an average age of 39 years at the time of the first consultation (extremes: 19 and 67 years). All seven patients presented with inflammatory polyarthralgia or non-deforming, non-erosive peripheral polyarthritis, without extra-articular manifestations. A biological inflammatory syndrome was present in all seven patients. Autoantibodies (rheumatoid factor, ANA, anti-ENA and ACPA) were negative in all patients. The first-line treatments in all seven cases were hydroxychloroquine (200 - 400 mg/day) and prednisone (5 - 10 mg/day). Methotrexate was added in 3 cases. During follow-up, 2 cases progressed to Polyarthritis Rheumatoid (PR) after 3 and 4 years. Two cases progressed to Sjögren’s syndrome after 4 and 5 years. Two patients progressed to systemic scleroderma after 5 and 8 years. One patient progressed to lupus after 5 years. Conclusion: Regular follow-up is essential in IAN. It allows the early diagnosis of IJR or a well-differentiated connective tissue disease and ensures adequate management, especially early.展开更多

文摘AIM:To examine the disparities in macular retinal vascular density between individuals with connective tissue disease-related interstitial lung disease(CTD-ILD)and healthy controls(HCs)by optical coherence tomography angiography(OCTA)and to investigate the changes in microvascular density in abnormal eyes.METHODS:For a retrospective case-control study,a total of 16 patients(32 eyes)diagnosed with CTD-ILD were selected as the ILD group.The 16 healthy volunteers with 32 eyes,matched in terms of age and sex with the patients,were recruited as control group.The macular retina’s superficial retinal layer(SRL)and deep retinal layer(DRL)were examined and scanned using OCTA in each individual eye.The densities of retinal microvascular(MIR),macrovascular(MAR),and total microvascular(TMI)were calculated and compared.Changes in retinal vascular density in the macular region were analyzed using three different segmentation methods:central annuli segmentation method(C1-C6),hemispheric segmentation method[uperior right(SR),superior left(SL),inferior left(IL),and inferior right(IR)],and Early Treatment Diabetic Retinopathy Study(ETDRS)methods[superior(S),inferior(I),left(L),and right(R)].The data were analyzed using Version 9.0 of GraphPad prism and Pearson analysis.RESULTS:The OCTA data demonstrated a statistically significant difference(P<0.05)in macular retinal microvessel density between the two groups.Specifically,in the SRL and DRL analyses,the ILD group exhibited significantly lower surface density of MIR and TMI compared to the HCs group(P<0.05).Furthermore,using the hemispheric segmentation method,the ILD group showed notable reductions in SL,SR,and IL in the superficial retina(P<0.05),as well as marked decreases in SL and IR in the deep retina(P<0.05).Similarly,when employing the ETDRS method,the ILD group displayed substantial drops in superficial retinal S and I(P<0.05),along with notable reductions in deep retinal L,I,and R(P<0.05).In the central annuli segmentation method,the ILD group exhibited a significant decrease in the superficial retinal C2-4 region(P<0.05),whereas the deep retina showed a notable reduction in the C3-5 region(P<0.05).Additionally,there was an observed higher positive likelihood ratio in the superficial SR region and deep MIR.Furthermore,there was a negative correlation between conjunctival vascular density and both deep and superficial retinal TMI(P<0.001).CONCLUSION:Patients with CTD-ILD exhibits a significantly higher conjunctival vascular density compared to the HCs group.Conversely,their fundus retinal microvascular density is significantly lower.Furthermore,CTD-ILD patients display notably lower superficial and deep retinal vascular density in comparison to the HCs group.The inverse correlation between conjunctival vascular density and both superficial and deep retinal TMI suggests that detecting subtle changes in ocular microcirculation could potentially serve as an early diagnostic indicator for connective tissue diseases,thereby enhancing disease management.
文摘Connective tissue diseases (CTDs) are Autoimmune diseases (AIDs) characterized by the appearance of autoantibodies, which are diagnostic markers. Investigations of these autoantibodies play a major role in the management of several autoimmune diseases. The objective of this study was to describe the profile of anti-ENA antibodies according to the clinical symptoms of mixed CTDs in Conakry teaching Hospital. We performed a cross-sectional study during six months. A total of 20 patients was recruited and we measured antibodies using the ELISA technique. The mean age of our patients was 36.5 years, with a predominance of females. Cutaneous and rheumatological signs were the main clinical manifestations. SLP was the most frequent CTDs;the threshold of ENA antibodies positivity was higher in scleroderma with and SLP. Anti-ENA identification reveals the frequency of anti-SSA (83.33%), anti-U1RNP (66.66%) and anti-histone (50%) antibodies. Antinuclear antibodies (ANA) react with various components of the cell nucleus. Their detection is of major interest in the diagnosis of CTDs. Our results highlight the importance of determining the specificity of these antibodies to guide differential diagnosis.

文摘Objective To investigate the prevalence of anti-endothelial cell antibodies (AECAs) in the sera of connective tissue diseases (CTD) patients with pulmonary arterial hypertension (PAH) and its correlation with clinical manifestations. Methods AECAs in sera of 39 CTD patients with PAH,22 CTD patients without PAH,and 10 healthy donors as controls were detected with Western blotting. The prevalence of different AECAs in different groups was compared and its correlation with clinical manifestations was also investigated. Results The prevalence of AECAs was 82.1% in CTD patients with PAH,72.7% in CTD patients without PAH,and 20.0% in healthy donors. Anti-22 kD AECA was only detected in CTD patients with PAH (15.4%). Anti-75 kD AECA was more frequently detected in CTD patients with PAH than in those without PAH (51.3% vs. 22.7%,P<0.05). In CTD patients with PAH,anti-75 kD AECA was more frequently detected in those with Raynaud’s phenomenon or with positive anti-RNP antibody. Conclusion AECAs could be frequently detected in CTD patients with or without PAH,while anti-22 kD and anti-75 kD AECA might be specific in CTD patients with PAH.

文摘BACKGROUND Fabry disease is a kind of lysosomal storage disease resulting from deficient activity of the lysosomal hydrolase alpha-galactosidase A(GLA). A mutation in the GLA gene leads to a loss of activity of alpha-galactosidase A. Some drugs,such as hydroxychloroquine, can cause pathological changes similar to those usually seen in Fabry disease.CASE SUMMARY We report the case of a 41-year-old female patient who was diagnosed with undifferentiated connective tissue disease in 2008. Hydroxychloroquine treatment started 2 years ago, and proteinuria and hematuria increased. Renal biopsy demonstrated renal phospholipidosis. Zebra bodies and myelin figures were found by renal electron microscopy and were initially thought to be indicators of Fabry disease. A genetic analysis of the patient and her family members did not reveal mutations in the GLA gene, supporting a diagnosis of hydroxychloroquine-induced renal phospholipidosis.CONCLUSION This report reveals one of the adverse effects of hydroxychloroquine. We should pay more attention to hydroxychloroquine-induced renal phospholipidosis.
文摘Hepatic injury is rarely associated with undifferentiated connective tissue diseases (UCTD). We report, here, a case of a middle-aged woman with UCTD-related hepatic injury, including its case history, clinical manifestations, laboratory findings, treatment and its short-term effect. The patient was admitted to the hospital with symptoms of fatigue, anorexia, low-grade fever and skin rashes. She had a past history of left knee joint replacement. Laboratory tests showed elevated levels of serum transaminase, IgG and globulin, accelerated erythrocyte sedimentation rate, eosinophilia and a high titer of antinuclear antibodies (1:320). Imaging studies showed interstitial pneumonitis and hydropericardium. Liver biopsy showed the features which were consistent with those of connective tissue diseases-related polyangitis. After treatment with a low-dose of oral prednisone, both symptoms and laboratory findings were significantly improved. UCTD-related hepatic injury should be considered in the differential diagnosis of connective tissue diseases with abnormal liver function tests. Low- dose prednisone may effectively improve both symptoms and laboratory tests.
文摘Introduction: Immunosenescence contributes to the development of auto-antibodies. However, while the prevalence of some autoantibodies increases with age, the incidence of connective tissue diseases decreases with age. This study aims to determine the clinical and paraclinical characteristics of connective tissue diseases in the elderly population. Materials and Methods: We conducted a retrospective and descriptive study, from March 2010 to March 2021, in the Internal Medicine Department of Aristide Le Dantec Hospital, including all the medical records of patients followed up for connective tissue disease and whose symptomatology began at an age greater than or equal to 65 years. Epidemiological, clinical, paraclinical, therapeutic and evolutionary data were collected from a pre-established survey form and then processed using SPSS software. Results: Overall, 22 cases were collected out of 275 seen on consultation. They involved 16 women and 6 men, aged between 65 and 85 years with a median of 70 years. The mean duration of the clinical picture was 15.7 months with extremes of 1 and 96 months. The clinical symptoms were joint pain in 21 patients associated with dry eye and mouth syndrome in seven cases and one patient underwent isolated dry eye and mouth syndrome. Joint involvement was deforming in 13 patients. Poor general condition was noted in 20 patients. Biology showed anemia in 14 patients, hyperleukocytosis (2 patients) and thrombocytosis (5 patients). The sedimentation rate (SR) was accelerated in 9 patients and the C-reactive protein (CRP) was positive in 12 patients. Immunology showed a positive Latex test (3 patients/6), Waaler-Rose reaction (8 patients/13), anti-cyclic citrullinated peptides (anti-CCP) antibodies (11 patients/11), anti-nuclear antibodies (2 patients/4). Anti-extractable nuclear antigens (anti-ENA) antibody testing in 4 patients showed positive anti-U1RNP (1 case), anti-SSA and anti-SSB (1 case). Plain X-Rays of the hands, wrists and feet showed destructive lesions in 16 patients. The diagnosis of rheumatoid arthritis (RA) was set in 21 patients, one of which was associated with Sjogren’s syndrome (SS) and one with primary Sjogren’s syndrome. Treatment was based on prednisone (21 cases), methotrexate (17 patients), and hydroxychloroquine (9 patients). The evolution was remarkable in 10 patients. Conclusion: Autoimmune diseases in the elderly are uncommon compared to the young adult population. In our study, we only found cases of rheumatoid arthritis and Sjogren’s syndrome. As the population ages, connective tissue diseases may be increasingly diagnosed.
文摘Mixed connective tissue disease (MCTD) is a rare systemic autoimmune disorder that damages multiple organs simultaneously and is associated with chronic inflammation, in which the signs of systemic sclerosis, systemic lupus erythematosus, and polymyositis can co-occur. Its distinctive feature and the basis for the diagnosis of MCTD is the presence of an antibody against the uridine-rich RNP of the cell nucleus (Anti-U1-RNP). It has been observed that intercurrent infections can trigger autoimmune diseases, however, the fact that viral infections—such as SARS-CoV-2—induce them is currently poorly understood. The present study raises the etiological role of the SARS-CoV-2 virus in the development of the disease. Authors describe the case of a 38-year-old patient in good general condition, who was diagnosed with mixed connective tissue disease three months after COVID-19 infection.

文摘Background:Accurate diagnosis of Pneumocystis jirovecii pneumonia(PJP)is challenging,and the delayed diagnosis of PJP is associated with high mortality in patients with connective tissue disease(CTD).Metagenomic next-generation sequencing(mNGS)technology facilitates etiological diagnosis of various infectious diseases,with promising application in diagnosing PJP.This study aimed to investigate the value of mNGS using bronchoalveolar lavage fluid(BALF)for diagnosing PJP infection.Methods:Data from 55 patients with CTD and suspected pulmonary infection was retrospectively collected and analysed.A PJP group and non-PJP group were formed.The clinical manifestations,laboratory test results,treatment methods,and outcomes were summarized.BALF mNGS results were compared with traditional pathogen tests(TPT)and serum 1,3-beta-D-glucan(BDG)testing.Results:The mean age of PJP patients was 54 years,and 59%(10/17)of the patients were female.A significant difference was found between the average daily dose of prednisone administered to the PJP group and non-PJP group(25 mg vs.16 mg,P<0.001).The PJP group had a significantly higher incidence of dyspnoea(88%[15/17]vs.16%[6/38],P<0.001)and elevated serum BDG level(167.73 vs.30.67 pg/mL,P<0.001).BALF mNGS was more sensitive than both TPT(100%[95%confidence interval{CI}:77.1%-100%]vs.11.8%[95%CI:2.1%-37.7%],P<0.001)and serum BDG(100%[95%CI:77.1%-100%]vs.85.7%[95%CI:42%-99.2%],P<0.001).BALF mNGS was more specific than serum BDG(89.5%[95%CI:74.3%-96.6%]vs.46.7%[95%CI:22.3%-72.6%],P=0.493).Co-infection with cytomegalovirus(CMV)was more common in the PJP patients than in the non-PJP patients(59%[10/17]vs.11%[4/38],respectively,P<0.001).Conclusion:BALF mNGS technology is highly effective for diagnosing PJP in patients with CTD and identifying co-infections.

文摘Background:Although antinuclear antibodies(ANAs),anti‐SSA and anti‐Ro52,are present in immunoglobulin preparations,it is unknown whether intravenous immunoglobulin(IVIG)therapy influences the testing of serum autoantibodies in patients with connective tissue diseases(CTDs).The present study aimed to investigate the dynamic change over time of serum ANA‐related autoantibodies in patients with CTDs receiving IVIG therapy.Methods:Serum ANA‐related autoantibodies were monitored in two patients with CTD before IVIG therapy and at different times after therapy.These autoantibodies were tested in different batches of immunoglobulin preparations from seven pharmaceutical companies.Results:One patient developed a new ANA pattern(cytoplasmic dense fine speckled pattern,AC‐19)just after IVIG therapy.Both patients developed de novo positivity for AMA‐M2 and anti‐SSA,but returned negative 1 month after IVIG therapy.The residual liquid in patients'immunoglobulin preparations showed positive ANAs with a high titer of AC‐19(1:640),a low titer of the nuclear fine speckled pattern(AC‐4,1:80),positive AMA‐M2,and positive anti‐SSA.ANA‐related autoantibodies were tested in 16 batches of immunoglobulin preparations and all had positive ANAs with two patterns:AC‐19(1:640 or 1:320)and AC‐4(1:80).AMA‐M2 and anti‐SSA were positive in 100%of the batches.Conclusion:Our study highlights high‐titer AMA‐M2 autoantibodies in immunoglobulin preparations and suggests their transient transfer into a patient's circulation via IVIG therapy.To avoid incorrect clinical decisions based on postinfusion antibody titers,our data recommend retesting 1–2 months after high‐dose IVIG immunomodulatory treatment.
文摘AIM: To help clarifying the possibility of connective-tissue diseases in men with penile or testicular prostheses. METHODS: Eight patients underwent inflatable penile prostheses and 15, testicular prostheses consented to the study. Their medical records were reviewed and a follow-up interview and physical and serological examinations were performed. RESULTS: In patients with penile prostheses, there was no abnormal antinuclear antibody (ANA) or IgM elevation. The serum levels of the rheumatoid factor (RF), C4, IgA and IgG were abnormal in one patient, and the levels of erythrocyte sedimentation rate (ESR) and C3, abnormal in two. Four had elevated IgE. In patients with testicular prostheses, there was no abnormal RF, ANA or IgM. The serum levels of ESR and IgA were abnormal in two, and three had abnormal C4, ten abnormal C3, and eleven decreased IgG. All had increased IgE. Men with penile prostheses had higher serum levels of IgG and IgM than those with testicular prostheses (P=0.001, P=0.016, respectively). The rates of abnormal values of IgE and IgG were higher in men with testicular prostheses than in men with penile prostheses (P=0.008, P=0.009, respectively). Physical examination was normal in all patients and nobody had documented symptoms pertinent to connective-tissue diseases. CONCLUSION: Our findings suggest that the risk of connective-tissue diseases is not higher in patients wearing prostheses as the ANA is negative and there is no apparent manifestation suggestive of connective-tissue diseases.
文摘Introduction: Systemic diseases are a variety of heterogeneous autoimmune and/or autoinflammatory diseases and syndromes usually affecting multiple systems and resulting from immune system dysregulation. We evaluated risk factors for depression and anxiety in an autoimmune disease cohort compared with diabetic patients. Patients and Methods: We conducted an observational, cross-sectional, case-control survey comparing two groups: individuals with connective tissue disease (CTD) and diabetic controls who were followed within three Dakar University hospitals during the period from April to June 2023. Results: The sample comprised 106 participants, of whom 51 (48%) had CTD and 55 (52%) served as diabetic controls. In the CTD group, the majority had lupus (19) and rheumatoid arthritis (23). The CTD patients had a mean age of 41.0 years (SD 16.9), while the diabetic patients had a mean age of 55.9 years (SD 11.7), with a significant difference observed (p Conclusion: Compared to a chronic disease, devastating in Africa and evolving over the long term, autoimmune diseases are more strongly and more frequently associated with anxiety and depression. This is a factor to be taken into account in the holistic management of these patients.

文摘AIM:To determine the utility of connective tissue growth factor(CCN2/CTGF) for assessing hepatic fibrosis in hepatitis B virus(HBV)-induced chronic liver diseases(CLD-B).METHODS:Enzyme-linked immunosorbent assay was used to measure CCN2 in sera from 107 patients with chronic hepatitis B(CHB) and 39 patients with HBVinduced active liver cirrhosis and 30 healthy individuals.Liver samples from 31 patients with CHB,8 patients with HBV-induced liver cirrhosis and 8 HBV carriers with normal liver histology were examined for transforming growth factor β-1(TGF-β1) or CCN2 mRNA levels by in situ hybridization,and computer image analysis was performed to measure integrated optimal density(IOD) of CCN2 mRNA-positive cells in liver tissues.Histological inflammation grading and fibrosis staging were evaluated by H and E staining and Van Gieson's method.RESULTS:Serum CCN2 concentrations were,respectively,4.0-or 4.9-fold higher in patients with CHB or active liver cirrhosis as compared to healthy individuals(P < 0.01).There was good consistency between the levels of CCN2 in sera and CCN2 mRNA expression in liver tissues(r = 0.87,P < 0.01).The levels of CCN2 in sera were increased with the enhancement of histological fibrosis staging in patients with CLD-B(r = 0.85,P < 0.01).Serum CCN2 was a reliable marker for the assessment of liver fibrosis,with areas under the receiver operating characteristic(ROC) curves(AUC) of 0.94 or 0.85 for,respectively,distinguishing normal liver controls from patients with F1 stage liver fibrosis or discriminating between mild and significant fibrosis.CONCLUSION:Detection of serum CCN2 in patients with CLD-B may have clinical significance for assessment of severity of hepatic fibrosis.
文摘Introduction: The association of systemic lupus erythematosus and rheumatoid arthritis (rhupus) is a rare clinical condition. Throughout the world, 287 cases of Rhupus have been described. We report two new observations of two patients who presented predominantly distal erosive polyarthritis with positive anti-Sm antibodies in one case and SmRNP in the other case. Observations: Case 1: 37 years old patient, with a recent diagnosis of pulmonary tuberculosis. She has since 8 months an inflammatory, bilaterally and symmetrical polyarthralgia without deformation or ankylosing synovitis, associated with malar erythema without other abnormalities. Immunological tests showed: positive Rheumatoid factor at 158 IU/ml, positive Anti-CCP at 550 IU/ml, and positivity of antinuclear at 1/1280 nuclear fluorescence with a strong presence of anti-Sm >8 IU/ml. The diagnosis of rhupus was concluded, without serious visceral involvement. Case 2: A 28-year-old patient, married with 3 children, with bilateral, symmetrical, deforming and chronic polyarthritis affecting large and small joints, which had been evolving for over 5 years without cutaneous abnormality associated. Paraclinical investigations showed: a biological inflammatory syndrome. Immunology was positive, with rheumatoid factors at 78 IU/ml, anti-CCP at 561 IU/ml, antinuclear antibodies at 1/1280 with positive anti-SmRNP and anti-SSA/Ro52, and a positive direct Coombs test. Joint ultrasound revealed tenosynovitis of the extensors and common flexors of the fingers, erosions and synovitis of multiple PPIs. The diagnosis of rhupus was based on the presence of 10 ACR criteria for RA and 8 ACR/EULAR 2019 criteria for SLE. Conclusion: Rheumatoid arthritis is a rare autoimmune disease combining features of both systemic lupus erythematosus and rheumatoid arthritis in the same patient, often sequentially. Despite a growing number of case reports and series, a consensus on the classification of SLE arthritis is still lacking, and diagnostic criteria for rhupus do not exist. These cases of rhupus must be recognized, as the vital and/or functional prognosis may be different from SLE alone or isolated RA.
文摘Background： Coronary artery disease （CAD） is a leading cause of morbidity and mortality in patients with connective tissue diseases （CTDs）. Risk factors and clinical characteristics in these patients are not equivalent to those in traditional CAD patients. The objective of this study was to report short- and long-term clinical outcomes in a consecutive series of patients with CTD who underwent percutaneous coronary intervention （PC1） with stent implantation. Methods： The study group comprised 106 consecutive patients with CTD who underwent PCI in Beijing Friendship Hospital between January 2009 and June 2012. Medical records were analyzed retrospectively including clinical basic material, coronary angiogram data, and the incidence of major adverse cardiac events （MACEs） during the short- and long-term （median 3 years） follow-up. Results： Ninety-two of the patients （86.8%） had one or more traditional CAD risk lhctors. Multivessel disease was present in more than 2/3 of patients （73.6%）. Tbe left anterior descending coronary artery was the most commonly affected vessel （65. 1%）. Five bare-metal stents and 202 drug-eluting stents were implanted. After a median follow-up period of 36 months, thirteen patients （12.3%） died from cardiac causes, the rate of stent thrombosis was 9.4%, and the rate of target vessel revascularization （TVR） was 14.2%. Multivariate analysis revealed that hypertension （hazard ratio [HR] = 3.07, 95% confidence interval [CI]： 1.30-7.24, P = 0.041 ）, anterior myocardial infarction （HR - 2.77. 95% CI： 1.06-7.03, P = 0.04）, longer duration of steroid treatment （HR - 3.60, 95% CI： 1.43-9.08, P 0.032）, and C-reactive protein level 〉10 mg/L （HR 3.98, 95% CI： 1.19 12.56, P = 0.036） were independent predictors of MACEs. Conclusions： Patients with CTD and CAD may have severe coronary lesions. PCI in these patients tends to result in an increased rate of stent thrombosis and TVR during long-term follow-up, which may be influenced by traditional and nontraditional risk factors.
文摘Marfan syndrome patients have connective tissue abnormalities that predispose them to intracardiac defects and postoperative complications.We present a case of late onset ASD device failure secondary to device movement within the atrial septum in a girl with Marfan syndrome.This case study suggests that further studies are necessary to determine the optimal device and approach for ASD repair in this patient cohort.
文摘We present a rare case of fecaloma, 7 cm in size, in the setting of systemic scleroderma. A colonoscopy revealed a giant brown fecaloma occupying the lumen of the colon and a colonic ulcer that was caused by the fecaloma. The surface of the fecaloma was hard, large and slippery, and fragmentation was not possible despite the use of various devices, including standard biopsy forceps, an injection needle, and a snare. However, jumbo forceps were able to shave the surface of the fecaloma and break it successfully by repeated biting for 6 h over 2 d. The ability of the jumbo forceps to collect large mucosal samples was also appropriate for achieving fragmentation of the giant fecaloma.
文摘Introduction: Unclassified inflammatory rheumatism is persistent inflammatory arthralgias with or without synovitis without sufficient classification criteria for an inflammatory rheumatism or a well-defined connective disease. Their outcome is variable and has been little studied in Africa. We report the epidemiological, paraclinical and evolutionary characteristics of seven cases of indeterminate polyarthritis. Material and Method: From January 2012 to May 2021, we selected all the files of patients followed up for unclassified inflammatory rheumatism and in whom a precise diagnosis was retained during the course of the disease. The diagnosis of unclassified inflammatory rheumatism was retained after biological, immunological and radiological explorations without specificities. Our study took place in the Internal Medicine Department of Aristide Le Dantec Hospital (HALD). Results: Seven cases out of 274 consulted were collected. They consisted of seven women with an average age of 39 years at the time of the first consultation (extremes: 19 and 67 years). All seven patients presented with inflammatory polyarthralgia or non-deforming, non-erosive peripheral polyarthritis, without extra-articular manifestations. A biological inflammatory syndrome was present in all seven patients. Autoantibodies (rheumatoid factor, ANA, anti-ENA and ACPA) were negative in all patients. The first-line treatments in all seven cases were hydroxychloroquine (200 - 400 mg/day) and prednisone (5 - 10 mg/day). Methotrexate was added in 3 cases. During follow-up, 2 cases progressed to Polyarthritis Rheumatoid (PR) after 3 and 4 years. Two cases progressed to Sjögren’s syndrome after 4 and 5 years. Two patients progressed to systemic scleroderma after 5 and 8 years. One patient progressed to lupus after 5 years. Conclusion: Regular follow-up is essential in IAN. It allows the early diagnosis of IJR or a well-differentiated connective tissue disease and ensures adequate management, especially early.
文摘A 25-year-old man with known dermatomyositis was admitted to the University of Leipzig Medical Centre for the first time.The diagnosis was originally made abroad years ago.Current laboratory studies showed elevated C-reactive protein and creatine kinase.Antinuclear antibodies,anti-Mi-2 antibodies,anti-Jo-1 antibodies,and anti-Scl-70 antibodies were negative,and the rheumatoid factor was positive.Nailfold video capillaroscopy(NVC)revealed numerous arborized(or“bushy”)capillaries reflecting dermatomyositis-typical neoangiogenesis.Physical examination showed extensive calcinosis cutis on arms,legs,and trunk.

文摘Background Aortic dissection remains one of the most acute and critical diseases in cardiac surgery,with high mortality and disability rates.In the 1960s,DeBakeyfirst proposed the classification of aortic dissection.Subsequently,various classifications of aortic dissection have been proposed.To facilitate clinicians and medical staff involved in the treatment of aortic dissection to make better assessment of the condition of aortic dissection patients and to make reasonable clinical decisions,we reviewed several current mainstream classification schemes.We hope that this paper inspires other researchers to propose a new,more suitable classification scheme for use in the clinical setting.
