Erythroderma, also known as exfoliative dermatitis, is a rarely reported atypical cutaneous manifestation of adult-onset Still's disease (AOSD). We present the case of erythroderma in association with AOSD that was steroid dependent and responded to tocilizumab therapy. Skin rash, pruritis, and related laboratory findings were significantly improved upon the addition of tocilizumab, while prednisolone was successfully tapered to an ever-lowest maintenance level. To our knowledge, this is the first to report the sole therapeutic effect of tocilizumab in erythroderma related to AOSD.

Isolated herpes zoster optic neuritis is a rare sequelae of herpes zoster ophthalmicus (HZO). It can occur in the acute phase of HZO, or as post-herpetic complications. We report a case of a young patient with poorly controlled diabetes who developed herpes zoster optic neuritis one month after the initial skin manifestation despite completing a two-week course of oral acyclovir 800 mg five times a day. He complained of a five-day history of sudden onset, painless left eye blurring of vision. His vision over the left eye was no light perception with the presence of a left relative afferent pupillary defect. Fundus examination of the left eye revealed a swollen optic disc. Magnetic resonance imaging showed minimal fat streakiness over the left orbit. He was treated with one week of intravenous methylprednisolone 1 g/day, followed by a tapering dose of oral prednisolone (1 mg/kg/day) together with oral acyclovir 800 mg five times a day for another week. His visual acuity remained poor with a slight improvement in vision to hand motion.

BACKGROUND
Mycophenolate dose reduction (MDR) is associated with acute rejection and transplant failure in kidney transplant recipients (KTRs). The optimal dose to prevent rejection and reduce complications remains poorly defined in tacrolimus-based regimens.
METHODS
We assessed adult KTRs from 2005 to 2017 initiated on mycophenolate mofetil 2 g/d, tacrolimus, and prednisolone from the Australia and New Zealand Dialysis and Transplant Registry. KTRs with rejection within the first 30 d posttransplant were excluded. The primary outcome was time to first rejection between 30 d and 2 y posttransplant. Mycophenolate dose was modeled as a time-varying covariate using Cox proportional hazards regression. Secondary outcomes included assessment of early MDR to <1.5 g/d within the first 6 mo posttransplant and subsequent patient and death-censored graft survival.
RESULTS
In the primary analysis, 3590 KTRs were included. Compared with mycophenolate dose of ≥2 g/d, both 1.0-<1.5 and <1 g/d were associated with an increased risk of rejection during the 2 y posttransplant (hazard ratio [HR] 1.67; 95% confidence interval [CI], 1.29-2.16; < 0.001 and HR 2.06; 95% CI, 1.36-3.13; = 0.001, respectively) but not 1.5-<2 g/d (HR 1.20; 95% CI, 0.94-1.53; = 0.14). Early MDR to <1.5 g/d occurred in 45.3% of KTRs and was an independent risk factor for death-censored graft failure (HR 1.32; 95% CI, 1.05-1.66; = 0.016) but not death (HR 1.18; 95% CI, 0.97-1.44; = 0.10), during a median follow-up of 5.0 (interquartile range, 2.6-8.5) y.
CONCLUSIONS
Early MDR was a risk factor for subsequent rejection and graft failure in KTRs receiving contemporary tacrolimus-based regimens.

BMC Geriatrics Jun 2024IgG4-related diseases are very uncommon, and its diagnosis and treatment are complicated as it encompasses multiple disciplines.
BACKGROUND
IgG4-related diseases are very uncommon, and its diagnosis and treatment are complicated as it encompasses multiple disciplines.
CASE PRESENTATION
A 77-year-old woman was admitted with a jaw mass and nausea and vomiting. Laboratory tests showed elevated serum IgG4, pituitary MRI suggested thickening of the pituitary stalk, and head and neck CT suggested orbital and mandibular masses. Patients with mandibular mass were diagnosed with Mikulicz's disease with IgG4-related hypophysitis. We found no other evidence of causing thickening of the pituitary stalk. She was given oral prednisolone 30 mg daily, and her nausea and vomiting improved significantly, and the mandibular and ocular masses decreased in size.
CONCLUSION
Mikulicz's disease combined with IgG4-related hypophysitis is a rare case of IgG4-RD in elderly women. IgG4-RD is one of the causes of head and neck exocrine gland mass and pituitary stalk thickening in the elderly.

Secondary lymphedema occurs after cancer surgery involving lymph node dissection owing to the lymphatic system dysfunction. However, the pathophysiology of lymphedema and the molecular pathways involved remain unknown. This study aimed to develop a rat hindlimb lymphedema model and investigate the mechanisms that drive pathophysiology and the effects of the traditional Japanese medicine goreisan on lymphedema. The rat lymphedema model was induced by combination surgeries of popliteal lymph node dissection, skin cautery incision, and fascial ablation coagulation in the right hindlimb using male Wistar rats. The foot volume was significantly increased, and recovery was delayed by combination surgeries. Dermal thickness and dilated lymphatic vessels of the hindlimb were observed on postoperative day 2. The number of infiltrating leukocytes (CD45 cells), including CD4 T-cells, increased in the lymphedema group compared with that in the sham group. The relative mRNA expression and protein levels of interleukin-6 (IL-6), CC chemokine ligand 2 (CCL2), transforming growth factor β1 (TGF-β1), and Fms-related receptor tyrosine kinase 4 (FLT4) were significantly higher in the lymphedema group than in the sham group. Foot volume was decreased by goreisan, furosemide, and prednisolone treatments. Goreisan diminished the increase in CD4 T-cells, and the same trend was observed for CCL2 and FLT4 expression. In conclusion, the rat hindlimb lymphedema model in this study exhibited increased foot volume, skin-infiltrating cells, and pathological changes accompanied by inflammatory and fibrotic responses, suggesting that the model presented significant clinical features of lymphedema. Goreisan may exert a therapeutic effect on lymphedema by inhibiting CD4 T-cell infiltration.

Thin films have been identified as an alternative approach for targeting sensitive site as drug delivery tool. In this work, the preparation of self-rolling thin films to form tubes for wound healing and easy placement (e.g. in the colon via colonoscopy) have been studied. We explored the use of thin films as a protective dressing combined to local release of an anti-inflammatory in order to improve drug efficacy and limit the side effects of the oral route. Non-cytotoxic poly(ethylene) glycol and poly(lactic acid) photo-crosslinkable star copolymers were used for rapid UV crosslinking of bilayered films loaded with prednisolone. The films, crosslinked under UV lamp without the need of photoinitiator, are optimized and compared in terms of water uptake, swelling ratio, final tube diameter and morphology, anti-inflammatory drug loading and release. Our studies showed the spontaneous rolling of bilayer constructs directly after immersion in water. Tubular geometry allows application of the patch through minimally invasive procedures such as colonoscopy. Moreover, the rolled-up bilayers highlighted efficient release of encapsulated drug following Fickian diffusion mechanism. We also confirmed the anti-inflammatory activity of the released anti-inflammatory drug that inhibits the pro-inflammatory cytokine IL-1β in RAW 264.7 macrophages stimulated by Escherichia coli (E. coli).

Clinical Drug Investigation Jun 2024Evidence on associations between drug-drug interactions (DDIs) and health outcomes in the older community-dwelling population is limited.
BACKGROUND
Evidence on associations between drug-drug interactions (DDIs) and health outcomes in the older community-dwelling population is limited.
OBJECTIVE
We estimate potentially clinically important DDI prevalence and examine the association between DDIs and (1) adverse drug events (ADEs), (2) emergency hospital attendance and (3) health-related quality of life (HRQoL) in an older community-dwelling population in Ireland.
METHODS
This is a prospective cohort study of community-dwelling older adults (N = 904) aged ≥ 70 years from 15 general practices in Ireland recruited in 2010 (wave-1) and followed-up over 2 years (wave-2; 2012-2013), with linked national pharmacy claims data. Individuals dispensed two or more drugs (wave-1: N = 842; wave-2: N = 763) were included. DDI prevalence at baseline, follow-up and 6 months prior to each health outcome was estimated. Multi-level regression was used to model the association between DDI-exposure and health outcomes at follow-up. DDI prevalence, adjusted incidence-rate ratios (aIRR), adjusted odds ratios (aOR), β coefficients and robust standard error (RSE) from multi-level regression analyses, and 95% confidence intervals (CIs) are reported.
RESULTS
At wave-1, n = 196 (23.3% [95% CI 20.5-26.3]), individuals were potentially exposed to ≥ 1 DDI, increasing to n = 345 (45.2% [41.7-48.9]) at wave-2. At 2-year follow-up, the median number of ADEs was 3 (interquartile range [IQR 2-5]); 229 (30.1%) had ≥ 1 emergency hospital attendance, and the mean EQ-5D was 0.74 (± 0.23). Evidence for the association between DDI-exposure and emergency hospital attendance at follow-up was lacking (aOR = 1.38 [0.42-4.53]). DDI-exposure was associated with an increasing number of ADEs (aIRR = 1.26 [1.03-1.55]), and decreasing EQ-5D utility (β = - 0.07, [-0.11 to -0.04], RSE = 0.02). Aspirin-warfarin, clarithromycin-prednisolone, amiodarone-furosemide, clarithromycin-salbutamol, rosuvastatin-warfarin, amiodarone-bisoprolol, and aspirin-nicorandil were common DDIs 6 months preceding these health outcomes.
CONCLUSIONS
We found a two-fold increase in DDI prevalence between wave 1 and 2. DDI exposure was associated with increasing ADEs and declining HRQoL at 2-year follow-up. Common DDIs involved anticoagulants, cardiovascular and antimicrobial drugs, which should be targeted for medicine optimisation.

Tuberculous pericardial effusion is uncommon in the developed countries. However, it remains one of the main causes of presentation with a pericardial presentation with pericardial effusion in the developing world. We present the case of a 24-year-old male patient who presented with a weekly history of diarrhoea, vomiting, shortness of breath and feeling hot. Chest computed tomography revealed a large pericardial effusion with significant haemodynamic compromise. The patient underwent emergency pericardiocentesis, and the pericardial fluid interferon-gamma assay result was positive for tuberculosis. He was unable to tolerate endobronchial biopsy under ultrasound despite heavy sedation and was commenced on anti-tuberculous therapy following a discussion in a multidisciplinary team meeting. He was started on four standard anti-tuberculosis medications, including rifampicin, isoniazid, pyrazinamide, ethambutol and prednisolone. The patient had re-accumulation of pericardial fluid on repeat echocardiography in the first few weeks, which eventually resolved with anti-tuberculous therapy.

A 64-year-old woman with a history of subarachnoid hemorrhage, breast cancer, cervical spine tumor, and syringomyelia developed recurrent pericardial effusion and cardiac tamponade after receiving the third dose of coronavirus disease 2019 mRNA vaccine, mRNA-1273 (Spikevax, Moderna). The cardiac tamponade of unknown etiology was intractable with nonsteroidal anti-inflammatory drugs, colchicine, and prednisolone. She underwent thoracoscopic pericardiectomy, and microthrombi were detected in the pericardial tissue. Although the exact causal relationship between vaccination and recurrent cardiac tamponade was unclear, the vaccine possibly caused or triggered the microthrombi formation, resulting in recurrent cardiac tamponade. Because of the potential for cardiovascular side effects such as thrombosis and myocarditis following vaccination, it was deemed necessary to accumulate and analyze such cases.

INTRODUCTION
The Coronavirus disease of 2019 (COVID-19) pandemic undoubtedly ranks among the most health-impacting pandemics throughout medical history. Although the COVID-19 global public health emergency has ended, lessons need to be learned to be more ready to face similar pandemics in the future. Few studies in Saudi Arabia discuss the impact of the COVID-19 pandemic on autoimmune rheumatic disease (AIRD) patients. Thus, this study was conducted to elaborate on the effects of the COVID-19 pandemic on AIRD patients and rheumatology practices in Saudi Arabia. Methods: This observational cross-sectional study was conducted among patients aged over 14 with AIRD using a pre-designed validated survey questionnaire. Data were collected from AIRD patients who were following up between November 2021 to April 2022 at the Rheumatology Clinic of King Fahad General Hospital in Madinah City, Saudi Arabia. This center was chosen as being the main hospital in the city following patients of AIRD.
RESULTS
A total of 324 patients were included in our study, with the majority (n=264, 81.5%) being females. The mean age was 44.42±14.4 years. Clinical data revealed that 115 (35.5%) of our patients experienced mild COVID-19 infection, 19 (5.9%) suffered from respiratory insufficiency, and seven (2.2%) required admission to the intensive care unit (ICU). Non-compliance to medication was recorded at 25.2%. There were 115 (35.5%) patients who had an AIRD flare that was significantly higher among those who were not adherent to the medications (p<0.001). Disease flare was also significantly seen among patients who were not on prednisone or were on low doses of prednisone (p<0.001). The majority (n=33, 97.1%) of the 34 infected patients who had an AIRD flare had their flare-up at the same time as their COVID-19 infection (p<0.001). COVID-19 vaccination rate was 87.7% (n=284). The most common reason for non-vaccination in 40 (12.3%) patients was the patients' concern about disease flare-ups by the vaccine or interference of the vaccine with their medication (n=16, 4.9%).
CONCLUSION
Our study showed a 35.5% (n=115) COVID-19 infection rate. The majority of our AIRD patients sustained minor infections that did not require hospitalization or ICU admission. The majority of the patients who underwent a severe COVID-19 infection course were not on prednisolone or were on low-dose prednisone. Due to COVID-19 restrictions and drug shortages, one in four patients (25.3%) stopped taking their medications and was significantly found to have a high prevalence of underlying AIRD flare. Despite the high vaccination rate, disease flare was the biggest concern for those who were not immunized. Although the COVID-19 pandemic has ended, doctors should be aware of risk factors associated with severe AIRD outcomes that should be balanced based on the infection severity, underlying disease flares, and patient-centered education about medication adherence and vaccination.
