KEY CLINICAL MESSAGE
The immunomodulatory effect of CMV makes coinfection with other microbes, like VZV possible and potentially deadlier in the post kidney transplant period. Treatment should be started promptly. Both infections can be treated with Valganciclovir.
ABSTRACT
Infections are common complications in kidney transplant recipients owing to the lifelong immunosuppression. Cytomegalovirus (CMV) and Varicella Zoster Virus (VZV) infections are quite common in the posttransplant period. Coinfection with both however has been reported only once. The immunomodulatory effect of CMV makes their interaction with other organisms like VZV potentially sinister. This is a case of a young woman who developed coinfection with HZV and CMV in the first month following a live related kidney transplantation from her mother. Transplant surgery went well with good urine output, but serum creatinine did not fall below 1.7 mg/dL. Immunosuppression consisted of intravenous (IV), followed by oral prednisolone, Mycophenolate Sodium (MPS) and Tacrolimus. 25 days after an uneventful surgery, she developed fever, followed by pain and vesicular eruption on the forehead, typical of VZV infection, along with rising creatinine. CMV PCR yielded 300 copies/mL of DNA, which was undetectable in both donor and recipient pre-transplant. Total white blood cell count fell to 2 × 10/L. MPS was temporarily stopped. Treatment with Valgancyclovir led to resolution of fever, skin lesions and brought serum creatinine down to baseline over 2 weeks.

Rheumatoid pleurisy is common in patients with rheumatoid arthritis, but distinguishing it from other diseases, such as heart failure and tuberculous pleurisy, is often difficult. A man in his 70s with stable rheumatoid arthritis presented with cardiac enlargement and bilateral pleural effusion on chest radiography. Pleural fluid studies showed lymphocytosis, adenosine deaminase level of 51.6 U/L and rheumatoid factor level of 2245.3 IU/mL, suggestive of rheumatoid pleurisy and tuberculous pleurisy. Thoracoscopy under local anaesthesia revealed erythema of the parietal pleura, small papillary projections and fibrin deposits. H&E-stained biopsy specimens showed inflammatory granulomas with strong lymphocytic infiltration and non-caseating granulomas. He was diagnosed with rheumatoid pleurisy. His symptoms improved with 30 mg of prednisolone. This study highlights that biopsy using thoracoscopy under local anaesthesia effectively diagnoses rheumatoid pleurisy, which may be challenging to diagnose.

CASE HISTORY
An 8-month-old male, entire, mixed-breed dog was presented with a 1-month history of left exophthalmos and green mucopurulent ocular discharge. Subsequently, exophthalmos resolved but esotropia (medial strabismus) developed in the left eye, prompting referral to an ophthalmologist.
CLINICAL FINDINGS
At the initial referral consultation, enophthalmos and esotropia of the left eye were identified. The patient showed mild improvement after a 3-week tapering course of oral prednisolone and doxycycline. MRI was performed and showed left medial rectus muscle atrophy with increased contrast enhancement which was consistent with chronic extraocular muscle myositis (EOM). A forced duction test was performed to confirm the diagnosis of fibrosing esotropia, which is likely a sequela of chronic EOM.
DIAGNOSIS
Fibrosing esotropia presumably caused by untreated EOM.
TREATMENT AND OUTCOME
One month later, esotropia progressed to a marked ventro-medial strabismus resulting in visual deprivation. Surgical release of the ventral oblique, medial and ventral recti muscles was performed, resulting in immediate resolution of the enophthalmos. Despite a tapering post-operative course of oral prednisolone, mild esotropia was present 4 weeks later. In an effort to stabilise the globe position, the low dose of prednisolone was increased to a higher anti-inflammatory dose before slowly tapering over 2 months. The vision in the left eye was improved after surgery and has been maintained since without further treatment.
CLINICAL RELEVANCE
This is the first documented case of fibrosing esotropia in a young dog with prior signs of acute exophthalmos. Fibrosing esotropia has been documented in certain breeds or as a sequela to chronic EOM. In this patient, it was presumably caused by EOM, which was strongly supported by the case history, progression and MRI findings. Most historical reports of EOM described it as a bilateral condition that resolves with systemic corticosteroids at an anti-inflammatory dose. EOM has been shown to also present unilaterally and it can progress to strabismus if not promptly recognised and treated with systemic steroids. Surgical management can restore vision when severe strabismus results in visual deprivation.

Red yeast rice has been used to produce alcoholic beverages and various fermented foods especially in East Asia. Since around March 2024, there have been many cases of kidney dysfunction in people who have taken certain supplements containing red yeast rice in Japan. We experienced a case of acute kidney injuries induced after taking a supplement containing red yeast rice. A 58-year-old woman was admitted to our hospital due to renal dysfunction suspected to be caused by taking the supplement Benikoji CholesteHelp, which contains red yeast rice. With elevations of urinary tubular injury markers such as urinary β2-microglobulin and N-acetyl-β-D-glucosaminidase, serum creatinine levels were elevated up to 2.75 mg/dL. A kidney biopsy revealed a diagnosis of tubulointerstitial nephritis with lymphocytic infiltration of the interstitium, tubular atrophy, and interstitial fibrotic changes. After discontinuation of the supplement and initiation of the prednisolone treatment, renal dysfunction rapidly improved. The course of this case suggests tubular damage caused by the supplements containing red yeast rice. For early diagnosis and treatment, it should be noted that even what are regarded as nutritional health supplements can cause renal dysfunction.

KEY CLINICAL MESSAGE
The co-occurrence of myasthenia gravis (MG) and lichen planus (LP) is a rare phenomenon, with only 13 cases reported in the English literature between 1971 and 2024. Patients with MG or LP, regardless of the thymoma status, require close monitoring for other autoimmune diseases.
ABSTRACT
Myasthenia gravis (MG) is an uncommon autoimmune disease, resulting in fatigable muscle weakness in the ocular, bulbar, and respiratory muscles, as well as muscles of the extremities. Lichen planus (LP) is an autoimmune mucocutaneous disease, presenting with pruritic and violaceous plaques on the skin and mucosal surfaces. So far, MG and LP co-occurrence is only reported in anecdotal individuals. This study reports a patient with MG and LP and systematically reviews the English literature on this rare co-occurrence from 1971 to 2024, indicating only 13 cases with similar conditions. A 67-year-old man presented with ocular and progressive bulbar symptoms, a year after being diagnosed with generalized LP. Laboratory evaluations were normal except for the high anti-AchR-Ab titer and a positive ANA titer. Neurologic examinations revealed asymmetric bilateral ptosis, weakness and fatigability in proximal muscles, and a severe reduction in the gag reflex. He was diagnosed with late-onset, seropositive MG. The treatment included pyridostigmine (60 mg, three times daily), intravenous immunoglobulin (25 g daily for 5 days), and oral prednisolone. There was no evidence of thymoma in the chest x-ray and CT scan without contrast. However, a CT scan with contrast was not performed due to the patient's unstable condition. A common autoimmune mechanism may underlie the unclear pathophysiology of MG and LP co-occurrence, with or without thymoma. Patients with MG, LP, or thymoma require close monitoring and assessment for other possible autoimmune diseases.

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.

Randomized Controlled Trial
Mycophenolate Mofetil with Steroid, a Reasonable Alternative to Current First-line Therapy, for Idiopathic Membranous Nephropathy in Resource-constrained Settings: A Randomized, Open-label Study.
BACKGROUND
The modified Ponticelli regimen (mPR) is a first-line therapy in patients with idiopathic membranous nephropathy (IMN); however, it has a less favorable safety profile. Though mycophenolate mofetil (MMF) + steroid (S) is not recommended by Kidney Disease Improving Global Outcomes guidelines, it can be used as an alternative to mPR due to higher tolerability and steroid-sparing effect. Thus, we compared the safety and effectiveness of MMF + S and mPR regimens in patients with IMN.
METHODS
This randomized, open-label study enrolled patients with adult-onset nephrotic syndrome (NS) and biopsy-proven IMN. Forty-two patients were allocated to MMF + S group (MMF 1 gm twice daily + oral prednisolone 0.5 mg/kg/day; = 21) and mPR group [methylprednisolone (1 gm intravenous) for 3 days followed by alternating monthly cycles of oral prednisolone (0.5 mg/kg/day) for the next 27 days and cyclophosphamide (2 mg/kg/day) for 6 months; = 21]. The primary outcome measure was change in urinary protein creatinine ratio (UPCR).
RESULTS
At 6 months, both groups demonstrated a significant increase in serum albumin levels and estimated glomerular filtration rate (eGFR) (both -values <0.0001) as well as a decrease in 24-hour proteinuria (MMF + S group: -value = 0.003, and mPR group: -value <0.0001) and UPCR (both -values <0.0001). However, the groups did not differ in any of these parameters at any of the monthly follow-up visits. Moreover, the groups did not differ significantly in terms of the composite remission rates (61.91% for MMF + S group and 71.43% for mPR group).
CONCLUSION
MMF + S and mPR had comparable tolerability and effectiveness, with MMF-associated advantage of reduced steroid exposure.

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.
