Systemic Sclerosis With a Normotensive Scleroderma Renal Crisis: A Diagnostic Dilemma.

Systemic sclerosis (SSc), also called scleroderma, is an auto-immune rheumatic disease that is characterized by fibrosis of the skin and internal organs and vasculopathy. Three of the severe manifestations of the disease include a scleroderma renal crisis (SRC), pulmonary arterial hypertension, and digital ulceration. Vascular manifestations like Raynaud's phenomenon are an almost universal symptom in patients with SSc and are often the earliest manifestation of the disease. An SRC occurs in approximately 10% of all patients with scleroderma. It is characterized by malignant hypertension and progressive renal failure. However, about 10% of SRC cases present with normal blood pressure or a normotensive renal crisis. A 65-year-old man with a history of peripheral vascular disease and newly diagnosed heart failure presented to the emergency department on account of progressive discoloration of the left big toe and intermittent confusion. Initially, he was noted to be hemodynamically stable, with bluish discoloration of his left lower extremity and left big toe, which was tender to palpation with palpable distal pulses. His left toe progressively became dusky and gangrenous, necessitating ray amputation by vascular surgery. His hospital course was further complicated by worsening acute kidney injury, requiring initiation of hemodialysis, and progressive hypoxia with the transition from room air to high-flow oxygen. As part of his workup for acute kidney injury (AKI), his antinuclear antibody (ANA) was found to be positive, with high titers, as well as elevated SCl-70 IgG. Despite the initiation of hemodialysis, and post-surgical revision, he continued to deteriorate. His family opted for comfort care measures, and he died a few days later. Although SSc is a rare disease, it is associated with significant morbidity and has one of the highest mortality rates among connective tissue diseases. SSc can present with heterogeneous manifestations, mimicking several isolated organ-specific conditions. This makes the diagnosis challenging, especially early in the course of the disease. A high index of suspicion, especially in the setting of rapidly progressing multi-organ involvement without a clear cause, should prompt further evaluation of systemic sclerosis.

Posterior Scleritis: A Case Report and Literature Review of the Management of the Condition.

Posterior scleritis is a rare inflammatory eye condition affecting the posterior segments of the sclera and is more prevalent in females. Its clinical presentation, often nonspecific, includes ocular pain, headache, and vision loss. Misdiagnosis is common due to a lack of specific symptoms posing a potential threat to vision. The etiology is often tied to rheumatic diseases, such as rheumatoid arthritis (RA), systemic erythematous lupus (SLE), and anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis. Posterior scleritis poses diagnostic challenges, mimicking many other ocular conditions, hence necessitating a thorough clinical eye exam. Laboratory studies, including inflammatory markers and markers of rheumatic diseases, may identify underlying systemic diseases. Imaging, including B-scan ultrasound and magnetic resonance imaging (MRI), aids in accurate diagnosis. Treatment involves non-steroidal anti-inflammatory drugs (NSAID), as well as topical corticosteroids for mild disease and systemic corticosteroids for severe disease. Biologic therapy has become increasingly significant for refractory cases. A multidisciplinary approach involving ophthalmology and rheumatology is crucial in the management of this potential sight-threatening disease. This case report highlights a 46-year-old woman with a history of RA-associated posterior scleritis.

Polymyositis/dermatomyositis readmissions: analysis of the nationwide readmission database.

BACKGROUND: There is a scarcity of national population-based studies on polymyositis (PM)/dermatomyositis (DM) readmissions in the USA. In this study, we aim to describe the rates, reasons for readmissions, and characteristics of readmissions for adults hospitalized for PM/DM in the USA. METHODS: We analyzed the 2018 Nationwide Readmissions Database (NRD). We included index hospitalizations for all adult DM/PM patients with a principal diagnosis of PM/DM using ICD-10 codes. We excluded elective and traumatic readmissions. Using a "rank" command in STATA, the most common specific principal diagnosis of readmissions was outlined. Chi-square tests were used to compare baseline characteristics between readmissions and index hospitalizations. STATA 16 was used for analysis. RESULTS: A total of 1610, 1286, and 842 index hospitalizations with a principal diagnosis of PM/DM, that were discharged alive, were included in the 30-, 90-, and 180-day readmission analysis, respectively. Among these, 193 (12%), 276 (21.5%), and 240 (28.5%) were readmitted within 30, 90, and 180 days, respectively. PM and sepsis were the most common reasons for reasons across the 3 timeframes. 30-day readmissions were responsible for an aggregate of 4.1 million US dollars in total hospital cost and 1518 hospital days in 2018. Compared to index hospitalizations, 30-day readmissions have higher Charlson Comorbidity Index scores, severe-extreme loss of function, obesity, and deep venous thrombosis. CONCLUSION: About a third of PM/DM hospitalized patients are readmitted within 180 days. Readmissions constitute a significant economic burden to the health care system. PM and sepsis are the main reasons for readmissions. Key points • About a third of polymyositis (PM)/dermatomyositis (DM) hospitalized patients are readmitted within 180 days • PM and sepsis are the main reasons for readmissions. • Readmissions of PM/DM Patients constitute a significant economic burden to the health care system. • Compared to index hospitalizations, 30-day readmissions have higher Charlson comorbidity index scores, severe-extreme loss of function, obesity, and deep venous thrombosis.

Systemic lupus erythematous readmissions have reduced: a 9-year longitudinal study of the nationwide readmission database.

BACKGROUND: Longitudinal data on the trends in systemic lupus erythematous (SLE) readmissions are limited. We aimed to study trends in 30-day readmissions of patients admitted for SLE flares and all SLE hospitalizations in the USA from 2010 to 2018. MATERIALS AND METHODS: Data were obtained from the nationwide readmission database (NRD). We performed a retrospective 9-year longitudinal trend analysis using the 2010-2018 NRD databases. We searched for index hospitalizations of adult patients diagnosed with SLE using the International Classification of Diseases (ICD) codes. Elective and traumatic readmissions were excluded from the study. Multivariable logistic and linear regression analyses were used to calculate the adjusted p value trend for categorical and continuous outcomes, respectively. RESULTS: The 30-day readmissions following index admissions of all SLE patients and for SLE flares decreased from 15.6% in 2010 to 13.3% in 2018 (adjusted p trend < 0.0001), and 20.3% in 2010 to 17.6% in 2018 (adjusted p trend = 0.009) respectively. Following SLE-flare admissions, hospital length of stay (LOS) decreased from 6.7 to 6 days (adjusted p trend = 0.045), while the proportion with a Charlson comorbidity index (CCI) score ≥ 3 increased from 42.2 to 54.4% (adjusted p trend < 0.0001) during the study period. SLE and its organ involvement, sepsis, and infections were common reasons for 30-day readmissions. CONCLUSION: About 1 in 5 SLE-flare admissions resulted in a 30-day readmission. The 30-day readmissions following index hospitalization for SLE flares and all SLE hospitalizations have decreased in the last decade. Although the readmission LOS was reduced, the CCI score increased over time. Key Points • The 30-day readmissions following index hospitalization for SLE flares and all SLE hospitalizations have reduced in the last decade although the CCI score increased over time. • SLE, its organ involvement, and infections are common reasons for readmission. • Infection control strategies, optimal management of SLE and its complications, and emphasis on an ideal transition of care are essential in reducing SLE readmissions.

Renal Involvement in Granulomatosis With Polyangiitis Increases Economic Health Care Burden: Insights From the National Inpatient Sample Database.

Background This study aims to compare outcomes of hospitalizations of granulomatosis with polyangiitis (GPA) with and without renal involvement. The primary outcome was inpatient mortality, whereas secondary outcomes were hospital length of stay (LOS) and total hospital charge. Methods Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 databases. The NIS was searched for GPA hospitalizations with and without renal involvement as the principal or secondary diagnosis using International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10) codes. GPA hospitalizations for adult patients from the above groups were identified. Multivariate logistic and linear regression analyses were used to adjust for possible confounders for the primary and secondary outcomes, respectively. Results There were more than 71 million discharges included in the combined 2016 and 2017 NIS database, of which 23,670 were for adult patients who had either a principal or secondary ICD-10 code for GPA, and 8,265 (34.92%) of these GPA hospitalizations had renal involvement. Hospitalizations for GPA with renal involvement had similar inpatient mortality (3.8% vs. 3.7%; adjusted OR: 1.14; 95% CI: 0.84-1.56; p=0.406) compared to those without renal involvement. GPA with renal involvement hospitalizations had an increase in adjusted mean LOS of 1.36 days (95% CI: 0.82-1.91; p=0.0001) compared to those without renal involvement. GPA with renal involvement hospitalizations had an increase in adjusted total hospital charges of $18,723 (95% CI: 9,595-27,852; p=0.0001) compared to those without renal involvement. Conclusions GPA with renal involvement hospitalizations had similar inpatient mortality compared to those without renal involvement. However, LOS and total hospital charges were greater in those with renal involvement.

Lung involvement in systemic sclerosis is associated with adverse hospital outcomes: insights from the National Inpatient Sample.

This study aimed to compare outcomes of systemic sclerosis (SSc) hospitalizations with and without lung involvement. The primary outcome was inpatient mortality while secondary outcomes were hospital length of stay (LOS) and total hospital charge. Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 database. This database is the largest collection of inpatient hospitalization data in the USA. The NIS was searched for SSc hospitalizations with and without lung involvement as principal or secondary diagnosis using International Classification of Diseases 10th Revision (ICD-10) codes. SSc hospitalizations for patients aged ≥18 years from the above groups were identified. Multivariate logistic and linear regression analysis was used to adjust for possible confounders for the primary and secondary outcomes, respectively. There were over 71 million discharges included in the combined 2016 and 2017 NIS database. 62,930 hospitalizations were for adult patients who had either a principal or secondary ICD-10 code for SSc. 5095 (8.10%) of these hospitalizations had lung involvement. Lung involvement group had greater inpatient mortality (9.04% vs 4.36%, adjusted OR 2.09, 95% CI 1.61 to 2.73, p<0.0001), increase in mean adjusted LOS of 1.81 days (95% CI 0.98 to 2.64, p<0.0001), and increase in mean adjusted total hospital charge of $31,807 (95% CI 14,779 to 48,834, p<0.0001), compared with those without lung involvement. Hospitalizations for SSc with lung involvement have increased inpatient mortality, LOS and total hospital charge compared with those without lung involvement. Collaboration between the pulmonologist and the rheumatologist is important in optimizing outcomes of SSc hospitalizations with lung involvement.

Psoriatic Arthritis Hospitalization Is Associated with Increased Health Care Charges: A Report from the National Inpatient Sample.

BACKGROUND: This study aims to compare the outcomes of psoriasis hospitalizations with and without joint involvement. The primary outcome was inpatient mortality, while secondary outcomes were hospital length of stay (LOS) and total hospital charges. METHODS: Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 databases. The NIS was searched for psoriasis hospitalizations with and without joint involvement as principal or secondary diagnosis using the International Classification of Diseases, tenth revision (ICD-10) codes. Psoriasis hospitalizations for adult patients (aged ≥18 years) from the above groups were identified. Multivariate logistic and linear regression analysis was used to adjust for confounders for the primary and secondary outcomes, respectively. RESULTS: There were over 71 million discharges included in the combined 2016 and 2017 NIS database. A total of 323,405 hospitalizations were for adult patients with either a principal or secondary ICD-10 code for psoriasis. Of these hospitalizations, 77,980 (24.11%) had joint involvement. Psoriasis hospitalizations with joint involvement had similar inpatient mortality (1.42% vs. 1.78%, adjusted odds ratio (AOR): 0.89, 95% CI: 0.76-1.05, p=0.159) compared with those without joint involvement. Psoriasis with joint involvement hospitalizations had a decrease in adjusted mean LOS of 0.15 days (95% CI: 0.26-0.04, p=0.007) compared with the group without joint involvement. Psoriasis with joint involvement hospitalizations had an increase in adjusted mean total hospital charges of $3,655 (95% CI: 2,146-5,164; p<0.0001) compared with the group without joint involvement. CONCLUSIONS: Hospitalizations for psoriasis with and without joint involvement have similar inpatient mortality. However, joint involvement increases total hospital charges, which increases the burden to the health care system.

Reasons for Hospitalization of Psoriasis Patients: A Report From the National Inpatient Sample.

Background We used a large United States population-based database to analyze the reasons for hospitalization of psoriasis patients. Methods International Classification of Diseases, 10th revision (ICD-10) code was used to identify hospitalizations in National Inpatient Sample (NIS) 2017 with a principal or secondary diagnosis of psoriasis. The reasons for hospitalization were divided into 19 categories based on their principal discharge ICD-10 diagnosis code. We also ranked the five most common specific reasons for hospitalization of psoriasis patients. Results There were over 35 million discharges included in the 2017 NIS database. A total of 165215 hospitalizations had either a principal or secondary ICD 10 code for psoriasis. Based on ICD-10 code categories, the top five reasons for hospitalization in patients with history of psoriasis were: Cardiovascular (CV) (26605, 16.10%), rheumatologic (19555, 11.84%), digestive (18465, 11.18%), infection (16395, 9.92%), and respiratory (14865, 9.00%). Sepsis was the most common principal diagnosis of psoriasis hospitalizations. Conclusion CV diseases were the most common ICD category, and sepsis was the most common principal diagnosis for psoriasis hospitalization. Management of medical co-morbidities is important in reducing rates of hospitalization of psoriasis patients.

Impact of Protein Energy Malnutrition on Outcomes of Adults With Viral Pneumonia: A Nationwide Retrospective Analysis.

Background Community-acquired pneumonia (CAP) is associated with significant morbidity and mortality. Viral organisms have been identified as the causal pathogen in approximately 20% of CAP. Nutritional status plays an important role in the response to pneumonia. This study aims to identify whether protein energy malnutrition (PEM) is an independent risk factor for mortality and morbidity in viral CAP. Materials and methods This was a retrospective cohort study involving adult hospitalizations for viral CAP in the United States using the Nationwide Inpatient Sample (NIS) database. This cohort was further divided based on the presence or absence of a secondary discharge diagnosis of PEM. The primary outcome was inpatient mortality. Secondary outcomes included the rate of mechanical ventilation among other complications. Results The in-hospital mortality for viral CAP was 2.22%. Patients with PEM had over two-fold high adjusted odds of inpatient mortality (aOR: 2.42, 95% CI: 1.746-3.351, p < 0.001) compared with patients without PEM. Patients with PEM had higher adjusted odds of having septic shock (aOR: 3.34, 95% CI: 2.158-5.160, p < 0.001). NSTEMI (aOR: 1.75, 95% CI: 1.163-2.621, p = 0.007), need for mechanical ventilation (aOR: 3.13, 95% CI: 2.448-4.006, p < 0.001), CVA (aOR: 3.49, 95% CI: 1.687-7.220, p = 0.001), DVT (aOR: 2.19, 95% CI: 1.453-3.295, p < 0.001), and PE (aOR: 2.24, 95% CI: 1.152-4.357, p = 0.017) relative to patients without PEM. Conclusion In conclusion, coexisting PEM is associated with a higher rate of in-hospital morbidity and mortality in patients with viral CAP. Early identification and treatment of nutritional deficiencies can lead to improved outcomes and reduced costs.

An Analysis of Rheumatoid Arthritis Hospitalizations.

Background We used a large United States (US) population-based database to analyze the reasons for hospitalization of rheumatoid arthritis (RA) patients. Methods The International Classification of Diseases, Tenth Revision (ICD-10) code was used to search for hospitalizations in 2017 in the National Inpatient Sample (NIS) database with RA as the principal or secondary diagnosis. The reasons for hospitalization were divided into 19 categories based on their principal discharge ICD-10 diagnosis code. We also ranked the five most common specific reasons for hospitalization. Results There were over 35 million discharges included in the 2017 NIS database; 565,440 hospitalizations had either a principal or secondary ICD-10 code for RA. The top five reasons for RA hospitalization by ICD-10 code categories were as follows: cardiovascular (CV): 93,825 (16.59%), rheumatologic: 82,785 (14.64%), respiratory: 66,895 (11.83%), infection: 62,660 (11.09%), and injury/poisoning: 56,460 (9.96%). Sepsis was the most common principal diagnosis for RA hospitalizations. Conclusion CV diseases were the most common ICD category, and sepsis was the most common principal diagnosis for RA hospitalizations. Management of medical comorbidities (such as CV) and prevention of infection is essential for reducing the rates of RA hospitalizations.
