Hypokalemic Paralysis due to Primary Sjögren Syndrome: Case Report and Review of the Literature Tue, 01 Aug 2017 08:18:09 +0000 http://www.hindawi.com/journals/crirh/2017/7509238/ Tubulointerstitial nephritis (TIN) is the main renal involvement associated with primary Sjögren syndrome (pSS). TIN can manifest as distal renal tubular acidosis (RTA), nephrogenic diabetes insipidus, proximal tubular dysfunction, and others. We present a 31-year-old female with hypokalemic paralysis due to distal RTA (dRTA). She received symptomatic treatment and hydroxychloroquine with a good response. There is insufficient information on whether to perform a kidney biopsy in these patients or not. The evidence suggests that there is an inflammatory background and therefore a potential serious affection to these patients, such as hypokalemic paralysis. We found 52 cases of hypokalemic paralysis due to dRTA in pSS patients. The majority of those patients were treated only with symptomatic medication. Patients who received corticosteroids had stable evolution even though they did not have another symptomatology. With such heterogeneous information, prospective studies are needed to assess the value of adding corticosteroids as a standardized treatment of this manifestation. A. Garza-Alpirez, A. C.

Granulomatosis with Polyangiitis Presenting as Pyrexia of Unknown Origin, Leukocytosis, and Microangiopathic Haemolytic Anemia Mon, 24 Jul 2017 08:03:16 +0000 http://www.hindawi.com/journals/crirh/2017/6484092/ A 66-year-old woman presented to the Emergency Department with a florid sepsis-like picture, a two-week history of fever, relative hypotension with end organ ischemia (unexplained liver enzyme and troponin elevations), and nonspecific constitutional symptoms. She was initially found to have a urinary tract infection but, despite appropriate treatment, her fever persisted and her white blood cell count continued to rise. During her hospitalization the patient manifested leukocytosis to 47,000 WBC/μL, ESR 67 mm/hr (normal range 0–42 mm/hr), CRP 17.5 mg/dL (normal range 0.02–1.20 mg/dL), and microangiopathic haemolytic anemia, with declining haemoglobin and haematocrit. An infectious aetiology was not found despite extensive bacteriologic studies and radiographic imaging. The patient progressed to acute kidney injury with “active” urinary sediment and proteinuria. Kidney biopsy results and serological titres of myeloperoxidase positive perinuclear-antineutrophil cytoplasmic antibodies (MPO+ p-ANCA) led to a diagnosis of granulomatosis with polyangiitis. Immunosuppressive treatment with high dose methylprednisolone and rituximab led to resolution of the leukocytosis and return of the haemoglobin and haematocrit values toward normal without further signs of hemolysis.

NXP-2 Positive Dermatomyositis: A Unique Clinical Presentation Tue, 13 Jun 2017 07:31:21 +0000 http://www.hindawi.com/journals/crirh/2017/4817275/ Dermatomyositis (DM), a myopathy associated with inflammation and muscle weakness, has historically been difficult to diagnose. Recently, nuclear matrix protein (NXP-2) antibodies have been described as a myositis-specific antibody that may aid in the diagnostic evaluation. We present the case of a 21-year-old, previously healthy, African American male with DM. He presented to our outpatient clinic with periorbital swelling and a rash, for which he was started on prednisone by an ophthalmologist. Towards the end of the prednisone taper, he began to experience muscle weakness, a worsening rash, and dysphagia to solids with a resultant loss of 60 pounds within a month. He was transferred to a tertiary care hospital where he was further evaluated and ultimately diagnosed with dermatomyositis, supported by skin and muscle biopsies, and was found to be positive for NXP-2. He was given intravenous immunoglobulin (IVIG) and high-dose steroids with improvement. Zeeshan Butt, Leeza Patel, Manash K. Das, Christopher A.

Improvement of Arterial Wall Lesions in Parallel with Decrease of Plasma Pentraxin-3 Levels in a Patient with Refractory Takayasu Arteritis after Treatment with Tocilizumab Tue, 06 Jun 2017 09:51:18 +0000 http://www.hindawi.com/journals/crirh/2017/4580967/ A 19-year-old Japanese woman with active Takayasu arteritis despite multiple conventional immunosuppressive therapies with glucocorticoids in combination with intravenous cyclophosphamide, azathioprine, or infliximab with methotrexate and tacrolimus was successfully treated by switching from infliximab to intravenous tocilizumab. Worsening of claudication of the legs and elevated acute phase reactants, including plasma pentraxin-3 levels, were observed during combination therapy with infliximab. Computed tomography demonstrated increased wall thickening with contrast enhancement in the preexisting lesion of the descending aorta and the femoral arteries. After switching from infliximab to tocilizumab, plasma pentraxin-3 levels gradually decreased to the normal range in parallel with the improvement of claudication. Follow-up computed tomographic scans confirmed the marked improvement of these arterial lesions. Moreover, plasma pentraxin-3 level was increased in response to the worsening of claudication that occurred just after switching to a subcutaneous tocilizumab injection. Measurements of plasma pentraxin-3 might be useful for evaluation of the vascular wall inflammation and therapeutic efficacy even during biologic therapy targeting tumor necrosis factor α and interleukin-6.

The Case of Reactive Arthritis Secondary to Echinococcus Infestation Sun, 21 May 2017 07:27:22 +0000 http://www.hindawi.com/journals/crirh/2017/3293060/ Reactive arthritis is an inflammatory joint disease that develops after an infection and it usually occurs following a gastrointestinal or genitourinary system infection and it belongs to the family of arthritis called “spondyloarthritis.” We wanted to represent a rare case of reactive arthritis secondary to Echinococcus infestation. Cyst hydatid disease is common in endemic regions like Turkey. Internal organ involvements, especially liver and lung, are most frequent involvements. Primary bone involvement is rare complication of Echinococcus infestation. In our case, the patient with Echinococcus infection developed right knee arthritis and sacroiliitis. Other reactive and oligoarthritis causes were excluded and diagnosis of reactive arthritis secondary to cyst hydatid infestation was done with the present findings. Cold pack and TENS treatment were applied as symptomatic treatment to the right knee of the patient. Acemetacin was given as medical treatment. On the 5th day of treatment, right knee and ankle arthritis were clinically regressed. In regions where the disease is seen as endemic, such as Turkey, patients with musculoskeletal symptoms should consider the possibility of musculoskeletal involvement due to the hydatid cyst.

Haematological Malignancies in Systemic Sclerosis Patients: Case Reports and Review of the World Literature Thu, 04 May 2017 00:00:00 +0000 http://www.hindawi.com/journals/crirh/2017/6230138/ Background. The association of systemic sclerosis (SSc) and haematological cancers was reported in a large number of case reports and cohort studies, describing SSc patients with highly heterogeneous clinical pictures. Objective. We reviewed the literature to better describe SSc patients with haematological malignancies. Methods. SSc cases complicated by haematological malignancies described in the world literature were collected; other 2 cases referred to our centre were reported. Results. One hundred-thirty SSc subjects were collected from 1954 up to date. The mean age of patients at cancer diagnosis was 56.1 ± 16.7 years; 72% of patients were females. In 60% of cases, the diagnosis of haematological malignancy was described within 5 years of SSc diagnosis. In 7.8% of cases, coexistence of Sjögren’s syndrome or other autoimmune disorders was cited. Sixty-six cases with lymphoma (in the majority of cases B-cell neoplasms), 28 with leukaemia (chronic lymphocytic form in 9), 14 with multiple myeloma plus one solitary IgM plasmocytoma, and 16 with myeloproliferative disorders were found. No specific SSc subsets seem to be related to haematological malignancies. Conclusions. We remarked the importance of clinical work-up in SSc, in order to early diagnose and treat eventual occult haematological malignancies, especially during the first years of the disease. M.

Mon, 24 Apr 2017 00:00:00 +0000 http://www.hindawi.com/journals/crirh/2017/8469629/ Sarcoidosis is a multisystem disorder of unknown etiology, characterized pathologically by the presence of nonnecrotizing granulomatous inflammation in affected organs. Although skeletal muscle is involved in 50–80 percent of individuals with sarcoidosis, symptomatic myopathy has been shown to be a rare manifestation of the disease. Inclusion body myositis (IBM) is a rare acquired idiopathic inflammatory myopathy with the insidious onset of asymmetric and distal muscle weakness that characteristically involves the quadriceps, tibialis anterior, and forearm flexors. Moreover, dysphagia can be the presenting complaint in one-third of patients. Herein, we are presenting a case of 67-year-old African American female who presented with one-month history of new onset progressive dyspnea on exertion. She was diagnosed with stage IV sarcoidosis based on chest CT scan findings and transbronchial lung biopsy revealing nonnecrotizing granulomatous inflammation. Over the next three months after her diagnosis, she presented to the hospital with progressive dysphagia associated with asymmetrical distal muscle weakness. A quadriceps muscle biopsy revealed features consistent with inclusion body myositis. We are reporting this case as it may support the hypothesis of sarcoidosis being a trigger that possibly promotes the development of inclusion body myositis, leading to a very poor prognosis.

SLE and Non-Hodgkin’s Lymphoma: A Case Series and Review of the Literature Mon, 27 Mar 2017 09:47:50 +0000 http://www.hindawi.com/journals/crirh/2017/1658473/ Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder punctuated by varied multiorgan complications all along the course of its natural history. Lymphoma represents a relatively well-recognized malignant phenomenon associated with lupus. The cause and effect relationships of lymphoma in SLE have been subject to extensive scrutiny with several studies reporting on clinic-pathologic characteristics and risk factors predicting lymphoma development in SLE. However, the pathogenic role of immunosuppressives in SLE-related lymphoma still remains unclear, and indices to help guide diagnosis, prognostication, therapy, and posttreatment monitoring are yet to be established. In this review, we describe 3 SLE patients who developed non-Hodgkin’s lymphoma at different time points of their disease. Through a careful dissection of the aforementioned cases, we intend to apprise readers of the currently available literature surrounding risk factors, management, and prognosis in SLE-related lymphoma. We will also review and discuss the implications of immunosuppressives in SLE-related lymphoma and the role of mycophenolate mofetil in SLE-related primary CNS lymphoma development.

The Child as a Surrogate for Diagnosis of Lupus in the Mother Mon, 13 Mar 2017 06:44:47 +0000 http://www.hindawi.com/journals/crirh/2017/8247591/ Introduction. Neonatal lupus erythematosus (NLE) is an acquired disease of the newborn caused by transplacental transfer of maternal anti-Ro/SSA, anti-La/SSB, and infrequently anti-U1 RNP antibodies. Methodology. This is a case report of a male infant delivered via Caesarean section at 36-week gestation following detection of fetal bradycardia during routine antenatal clinic visit. Results. The mother was seropositive for antinuclear antibody (ANA) and anti-Ro/SSA and had elevated erythrocyte sedimentation rate. The baby was positive for ANA, extractable nuclear antigen (ENA), and anti-Ro/SSA. Pediatric echocardiography was abnormal and electrocardiography confirmed complete heart block. Olufemi O.

An Unusual Presentation of Limited Granulomatosis with Polyangiitis Involving Vagina and Urethra Mon, 13 Mar 2017 00:00:00 +0000 http://www.hindawi.com/journals/crirh/2017/9407675/ Granulomatosis with polyangiitis (GPA) is a systemic necrotizing granulomatosis vasculitis characterized by predilection to affect small- and medium-sized blood vessels and commonly affects the upper and lower respiratory tract and kidneys in most cases. Genital involvement is reported in <1% of cases in large cohorts and nearly all cases have been in the setting of multisystemic disease or during the course of the disease in patients already diagnosed as GPA. A case is presented of uncommon limited urogenital GPA in a 66-year-old woman with an irregular mass occupying urethra and vagina. The patient showed a good response after Corticoids and Methotrexate.

A 64-Year-Old Woman with Chest Pain, Limb Weakness, and Endometrial Cancer Wed, 08 Mar 2017 00:00:00 +0000 http://www.hindawi.com/journals/crirh/2017/1891897/ Necrotizing autoimmune myopathy (NAM) is a rare subgroup of idiopathic inflammatory myopathies (IIM). This pathology usually affects proximal limb muscles and in some cases the myocardium. Patients usually display proximal limb weakness. Muscular biopsy is required to confirm the diagnosis. We report the case of a 64-year-old woman with an atypical first presentation of NAM, manifested by chest pain in the context of metastatic endometrial cancer. The diagnosis of NAM was however made when she returned a second time with proximal limb weakness. A treatment with prednisone was then initiated, to which rituximab was rapidly associated, beside a specific chemotherapy.

A Rare Case of Digital Ischemia and Gangrene in ANCA-Associated Vasculitis with Review of the Literature Tue, 28 Feb 2017 09:12:09 +0000 http://www.hindawi.com/journals/crirh/2017/2421760/ This paper describes one patient with Antineutrophil Cytoplasmic Antibody- (ANCA-) associated vasculitis who initially presented with multiple ischemic fingers and toes. On further evaluation, the patient was also found to have pulmonary-renal involvement and episcleritis. The diagnosis was supported with a positive cANCA (anti-proteinase 3) and a bronchoscopy consistent with diffuse alveolar hemorrhage. Although the patient refused a tissue biopsy, clinical presentation including nasal ulceration, sinus congestion, and epistaxis and anti-proteinase 3 antibody were more consistent with Granulomatosis with Polyangiitis (GPA) rather than Microscopic Polyangiitis (MPA) or Eosinophilic Granulomatosis with Polyangiitis (EGPA) based on the recently presented ACR/EULAR Provisional 2017 Classification Criteria for GPA (Luqmani et al., 2016). The patient responded well to therapy including high dose steroids and cyclophosphamide, with improvement of all organs involved and had no further digital ischemia or gangrene on follow-up. We include a review of the English literature summarizing presentation, management, and outcome of 16 similar cases. Richard A. Lau, Ramandeep Bains, Duminda Suraweera, Jane Ma, Emil R.

Tue, 21 Feb 2017 00:00:00 +0000 http://www.hindawi.com/journals/crirh/2017/1609247/ Progressive pseudorheumatoid dysplasia (PPD) or spondyloepiphyseal dysplasia tarda with progressive arthropathy (SEDT-PA) is a rare arthropathy of childhood involving the axial skeleton as well as small peripheral joints. A 10-year-old boy was referred by a general practitioner with pain and deformity in the fingers of hands and limping gait. There was no joint synovitis although the finger joints were bulky on examination with mild flexion deformity. Patient had exaggerated kyphosis and lumbar lordosis with pigeon chest and restricted hip joint movements. Anteroposterior X-rays of the hip joints revealed widened and flattened epiphyses of the femoral heads with narrow and irregular joint spaces. Hand X-rays revealed periarticular osteopenia, significant narrowing of the joint spaces of proximal interphalangeal, and distal interphalangeal joints, together with osseous enlargement of the basis of metacarpal bones and phalanges. Spinal X-rays revealed generalized platyspondyly and anterior beaking of vertebral bodies. There was a clear mega os trigonum in his feet images. All blood investigations were normal with no evidence of inflammation and thyroid hormone levels were normal. The diagnosis of PPD was favored by imaging studies and normal inflammatory markers and the patient was treated with physiotherapy, family counseling, and anti-inflammatory medications.

Antiproteinase 3 Positive Eosinophilic Granulomatosis with Polyangiitis Presenting with Heart Failure and Intraventricular Thrombosis Sun, 29 Jan 2017 00:00:00 +0000 http://www.hindawi.com/journals/crirh/2017/2908185/ Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis commonly with cardiac complications. We describe a case of anti-PR3 ANCA-positive EGPA complicated by congestive heart failure and intraventricular thrombosis. Interestingly, the thrombus was resolved rapidly with steroid and cyclophosphamide in the setting of interrupted anticoagulation. To the best of our knowledge, we report the first case of anti-PR3 positive EGPA with extensive cardiac involvement. Our patient had overlapping features with previously studied ANCA-positive and ANCA-negative EGPA cases. We also hypothesize that the thrombogenic potential of eosinophils may play a central role in thrombogenesis in EGPA and aggressive immunosuppressive therapy remains the cornerstone of treatment, and the addition of anticoagulation therapy in the setting of thrombus formation and also very high risk of bleeding needs to be considered cautiously.

Hydralazine Induced Lupus Syndrome Presenting with Recurrent Pericardial Effusion and a Negative Antinuclear Antibody Tue, 17 Jan 2017 07:58:56 +0000 http://www.hindawi.com/journals/crirh/2017/5245904/ Drug induced lupus erythematosus (DIL or DILE) is an autoimmune disorder caused by chronic use of certain drugs. We report a unique case of hydralazine induced lupus syndrome (HILS) with a negative antinuclear antibody in a female patient who was on hydralazine for a period of 1.5–2 years and developed recurrent pericardial effusion as a result of it. Initially her condition was managed with a pericardial window. The recurrence of a massive pericardial effusion necessitated a right hemipericardiectomy. After hydralazine was stopped, she never had any further episodes of pericardial effusion or tamponade. Praneet Iyer, Ahmed Dirweesh, and Ritika Zijoo Copyright © 2017 Praneet Iyer et al.

Hypertrophic osteoarthropathy (HOA) is a syndrome characterized by abnormal proliferation of the skin and bony structures at the distal extremities resulting in digital clubbing, periosteal bony reaction, and joint effusion. It can be primary (idiopathic) without any clear identifiable etiology as well as secondary to variety of systemic diseases most notably lung pathology. Case Presentation. We describe a rare case of primary idiopathic osteoarthropathy in a male patient who presented with severe pain and tenderness in his legs. His history was significant for long standing alcoholism. Physical examination showed severe fingers and toes clubbing. He reported similar changes in his mother. Clinical and radiological findings were remarkable for distal leg tenderness and diffuse periosteal bony reactions, respectively. Computerized tomography scan failed to show any pathology apart from fatty liver infiltration. In the absence of obesity or diabetes, this was consistent with alcoholic steatosis. He was started on nonsteroidal anti-inflammatory drug which dramatically improved his symptoms. Conclusion. Primary hypertrophic osteoarthropathy should be considered in a previously healthy person presenting with bony pain and finger clubbing especially after ruling out the common secondary causes. Moreover, alteration of prostaglandin metabolism secondary to alcoholic consumption might be a contributing factor.

A Unique Case of Systemic Lupus Erythematosus Pelvic Vasculitis Thu, 29 Dec 2016 14:43:35 +0000 http://www.hindawi.com/journals/crirh/2016/6347901/ The clinical presentation of Systemic Lupus Erythematosus (SLE) is diverse and vasculitis can be a potential manifestation. Cutaneous lesions involving small vessels are the most frequent presentation. However, medium and large vessel vasculitis may present with life-threatening visceral manifestations. We present a unique case of pelvic vasculitis mimicking a pelvic mass as an initial presentation of SLE. There are case reports of systemic vasculitis involving the female genital tract with giant cell arteritis (GCA), polyarteritis nodosa (PAN), and granulomatous with polyangiitis and microscopic polyangiitis (GPA/MPA), among others, but only a few cases attributed to SLE. Awareness of this condition and a prompt diagnosis are warranted as this is a severe and potentially life-threatening condition.

Thu, 15 Dec 2016 09:14:50 +0000 http://www.hindawi.com/journals/crirh/2016/8219317/ Activation of the classical pathway complement system has long been implicated in stimulating immune complex mediated tissue destruction in systemic lupus erythematosus (SLE). C3 and C4 complement levels are utilized as part of SLE diagnosis and monitoring criteria. Recently, cell bound complement activation products (CBCAPs) have shown increased sensitivity in diagnosing and monitoring lupus activity, compared to traditional markers. CBCAPs are increasingly utilized in rheumatology practice as additional serological markers in evaluating SLE patients. We report a case of a patient diagnosed with SLE that had chronically low C3 and C4, along with negative CBCAPs. We surmise that the patient has an inherited complement deficiency as the etiology of her SLE and that CBCAPs could be used to predict such deficiency.

Chronic and Asymptomatic Diffuse Alveolar Haemorrhage with Microscopic Polyangiitis: A Case Report and Review of the Literature Mon, 05 Dec 2016 12:05:47 +0000 http://www.hindawi.com/journals/crirh/2016/1658126/ Diffuse alveolar haemorrhage (DAH) is one of the major causes of death in microscopic polyangiitis (MPA) patients, because of acute respiratory failure with various respiratory symptoms. We, herein, present a case of chronic and asymptomatic DAH in a patient with MPA who was diagnosed by fibreoptic bronchoscopy. The patient showed localized reticular shadows, without any respiratory symptoms, and absence of inflammatory reactions, such as fever and CRP elevation, which is atypical for DAH. Three months after appearance of the lung abnormalities, DAH with MPA was diagnosed by fibreoptic bronchoscopy. She was initially treated with only corticosteroids and has thereafter been maintained with corticosteroids and azathioprine without relapse to date. We reviewed the literature for similar cases and opined that physicians should perform fibreoptic bronchoscopy in MPA patients with chronic lung abnormalities and anaemia to identify DAH, even if the patients show no respiratory symptoms and in the absence of inflammatory reactions.

Combination Immunosuppressive Therapy Including Rituximab for Epstein-Barr Virus-Associated Hemophagocytic Lymphohistiocytosis in Adult-Onset Still’s Disease Mon, 28 Nov 2016 11:26:13 +0000 http://www.hindawi.com/journals/crirh/2016/8605274/ Hemophagocytic lymphopcytosis (HLH) is a life-threatening condition. It can occur either as primary form with genetic defects or secondary to other conditions, such as hematological or autoimmune diseases. Certain triggering factors can predispose individuals to the development of HLH. We report the case of a 25-year-old male patient who was diagnosed with HLH in the context of adult-onset Still’s disease (AOSD) during a primary infection with Epstein-Barr virus (EBV). During therapy with anakinra and dexamethasone, he was still symptomatic with high-spiking fevers, arthralgia, and sore throat. His laboratory values showed high levels of ferritin and C-reactive protein. His condition improved after the addition of rituximab and cyclosporine to his immunosuppressive regimen with prednisolone and anakinra. This combination therapy led to a sustained clinical and serological remission of his condition. While rituximab has been used successfully for HLH in the context of EBV-associated lymphoma, its use in autoimmune diseases is uncommon. We hypothesize that the development of HLH was triggered by a primary EBV infection and that rituximab led to elimination of EBV-infected B-cells, while cyclosporine ameliorated the cytokine excess. We therefore propose that this combination immunosuppressive therapy might be successfully used in HLH occurring in the context of autoimmune diseases.

Swift and Complete Healing of Digital Ulcers after Macitentan Treatment Tue, 22 Nov 2016 13:46:13 +0000 http://www.hindawi.com/journals/crirh/2016/1718309/ Digital ulcers are a burdensome and painful condition with sparse options of treatment. We report the case of a 78-year-old female patient with limited cutaneous systemic sclerosis that sequentially developed digital ulcers. After the appearance of digital ulcers in the soles of her feet she was successfully treated with bosentan. The report of two new digital ulcers in her hands 9 months later alongside with elevated transaminase levels led to a switch to macitentan treatment. A swift and complete healing of both digital ulcers was observed after 3 months, with the restoration of normal biochemical values. Emilio Giner Serret Copyright © 2016 Emilio Giner Serret.

A Case of Dermatomyositis and Anti-EJ Autoantibody with Chronic Intestinal Pseudoobstruction Successfully Treated with Octreotide Thu, 03 Nov 2016 07:47:58 +0000 http://www.hindawi.com/journals/crirh/2016/9510316/ Chronic intestinal pseudoobstruction (CIPO) is a serious complication in patients with connective tissue disease (CTD) and is sometimes life-threatening or fatal despite intensive medical treatment. Here, we report a patient with dermatomyositis (DM) and anti-EJ autoantibody who developed CIPO that was improved by octreotide. Because her abdominal pain and bloatedness were so severe and persistent, we introduced octreotide to relieve symptoms. In this case, continuous intravenous administration as well as long-acting subcutaneous injection of octreotide was effective for treating CIPO.

Rituximab was not effective in ameliorating the hearing loss in a patient with atypical Cogan’s syndrome. Observations. We report the case of a patient who developed acute bilateral uveitis and sensorineural hearing loss. A diagnosis of atypical Cogan’s syndrome was made. The patient’s hearing loss did not improve despite high dose steroids and azathioprine. Rituximab was administered given a recent report of its efficacy in a patient with refractory disease; however, our patient’s hearing loss did not improve. Conclusion. Hearing loss in Cogan’s syndrome is difficult to treat. Though rituximab was ineffective in our case, earlier administration in the disease course could be effective for future patients. Daniel R.

Hemorrhagic Pericardial Effusion with Tamponade: A Rare Adverse Effect of Infliximab—Case Report and Literature Review Sun, 16 Oct 2016 07:57:50 +0000 http://www.hindawi.com/journals/crirh/2016/2576496/ Introduction. Antitumor necrosis factor (TNF) alpha agents are commonly used biologic therapies for a wide variety of rheumatic and inflammatory diseases. Here, we present a case of hemorrhagic pericarditis as a consequence of infliximab and review the literature on pericardial complications stemming from this drug class. Methods. For the literature review, search terms using versions of antitumor necrosis factor alpha AND pericardial effusion OR pericarditis OR pleuropericarditis OR cardiac tamponade were used. Results. Pericarditis is a rare but serious complication of anti-TNF based therapy, and hemorrhagic fluid is even more rare, with only one additional case reported. It is likely that this complication was secondary to a robust immune response to very high titer anti-infliximab antibodies. Providers should be aware that this complication can occur and that abnormal elevations in procalcitonin may accompany this unusual finding. Henry D. Lather and J.

Macrophage Activation Syndrome Associated with Adult-Onset Still’s Disease Successfully Treated with Anakinra Wed, 12 Oct 2016 07:17:08 +0000 http://www.hindawi.com/journals/crirh/2016/3717392/ Macrophage activation syndrome (MAS) is a potentially fatal complication of Adult-Onset Still’s disease (Still’s disease). Whereas an increasing body of evidence supports interleukin-1 (IL-1) blockade as a promising treatment for Still’s disease, whether it is therapeutic for MAS associated with Still’s disease remains unclear. We report a 34-year-old Caucasian man with one-decade history of TNF-blockade-responsive seronegative arthritis who presented with abrupt onset of fever, serositis, bicytopenia, splenomegaly, hepatitis, and disseminated intravascular coagulation. Striking hyperferritinemia was noted without evidence of infection, malignancy, or hemophagocytosis on bone marrow biopsy. NK cells were undetectable in the peripheral blood, whereas soluble IL-2 receptor was elevated. His multiorgan disease resolved in association with methylprednisolone pulse therapy, Anakinra, and a tapering course of prednisone. This case reinforces the notion that Still’s disease is inherently poised to manifest MAS as one of the clinical phenotypes by shedding light on the role of IL-1 underlying both Still’s disease and related MAS.

Coexistent Pseudogout and Mycobacterium avium-intracellulare Septic Arthritis in a Patient with HIV and ESRD Mon, 10 Oct 2016 09:36:35 +0000 http://www.hindawi.com/journals/crirh/2016/5495928/ Pseudogout is a crystal-induced arthropathy characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in synovial fluid, menisci, or articular cartilage. Although not very common, this entity can be seen in patients with chronic kidney disease (CKD). Septic arthritis due to Mycobacterium avium-intracellulare (MAI) is a rare entity that can affect immunocompromised patients such as those with acquired immunodeficiency syndrome (AIDS) or those who are on immunosuppressive drugs. Here, we describe a 51-year-old female who presented with fever, right knee pain, swelling, warmth, and decreased range of motion for several days. The initial assessment was consistent with pseudogout, with negative bacterial and fungal cultures. However, due to high white blood cell (WBC) count in the synovial fluid analysis, she was empirically started on intravenous (IV) vancomycin and piperacillin-tazobactam and discharged on IV vancomycin and cefepime, while acid-fast bacilli (AFB) culture was still in process. Seventeen days later, AFB culture grew Mycobacterium avium-intracellulare (MAI), and she was readmitted for relevant management. This case illustrates that septic arthritis due to MAI should be considered in the differential diagnosis of septic arthritis in immunocompromised patients. Wais Afzal, Omer M. Wali, Kelly L.

Adult Onset Henoch-Schonlein Purpura and Intussusception: A Rare Presentation Mon, 26 Sep 2016 16:39:14 +0000 http://www.hindawi.com/journals/crirh/2016/3957605/ We present an unusual case of a young 26-year-old male who was diagnosed with Henoch-Schonlein Purpura (HSP). Initial presentation was primarily mild gastrointestinal symptoms, which progressed to a life threatening intussusception and subsequently resolved with prompt glucocorticoid use rather than typical surgical intervention. Of importance, the patient’s initial gastrointestinal symptoms without associated skin manifestations made the diagnosis difficult. In conclusion, it is important to recognize uncommon presentations of HSP as it may lead to life threatening complications and surgical intervention may be avoided with prompt treatment.

A Case of Abdominal Aortic Retroperitoneal and Mesenteric Amyloid Light Chain Amyloidoma Mon, 26 Sep 2016 06:18:30 +0000 http://www.hindawi.com/journals/crirh/2016/4146030/ We report the case of a Japanese woman with amyloid light chain (AL) amyloidoma in the abdominal aortic retroperitoneum and mesentery. Irregular soft tissue mass lesions with calcification in the abdominal aortic retroperitoneum and mesentery were initially detected by computed tomography at another hospital. The lesions gradually compressed the duodenum, causing symptoms of bowel obstruction. The patient was clinically diagnosed with retroperitoneal fibrosis, and prednisolone was administered at a dose of 40 mg/day. However, the lesions did not change in size and her symptoms continued. She was transferred to our hospital and underwent mesenteric biopsy for histopathology using abdominal laparotomy. The histopathological and immunohistological findings of the mesenteric specimen demonstrated lambda light chain deposition. Accordingly, the patient was finally diagnosed with AL amyloidoma with no evidence of systemic amyloidosis. After laparotomy, her general condition worsened because of complications of pneumonia and deep vein thrombosis. She died suddenly from acute myocardial infarction. We have concluded that abdominal aortic retroperitoneal and mesenteric AL amyloidoma may have very poor prognoses in accordance with previous reports. In addition, the size and location of AL amyloidoma directly influence the prognosis. We suggest that early histopathology is important for improving prognosis.

A Curious Case of Proximal Muscle Weakness with Eosinophilic Polymyositis Wed, 14 Sep 2016 14:31:18 +0000 http://www.hindawi.com/journals/crirh/2016/7810916/ Eosinophilic polymyositis (EPM) is part of a rare disorder, eosinophilic myopathies (EM), which is a form of polymyositis characterized by the presence of eosinophils in muscle biopsy sections and occasionally blood eosinophilia. Herein, we are presenting an interesting case of eosinophilic polymyositis presenting with muscle pain with no other organ systems involved.
