Abstract
Colchicine myopathy typically presents acutely to subacutely with progressive limb weakness. The patients may not be on high doses of colchicine but almost always have acute kidney injury. Dehydration from colchicine-induced diarrhoea is often a precipitating factor. The concomitant neurotoxicity may produce mild sensory complaints. This combination of acute neurological symptoms preceded by diarrhoea prompts the diagnosis of Guillain-Barre syndrome (GBS). The absence of cranial nerve deficits, raised creatine kinase and myotonic discharges on electromyogram may help in differentiating this condition from GBS. We describe a clinical sign, myoedema - a mounding phenomenon of muscle that is elicited by percussion and resolves when the patient recovers. It aids in the bedside diagnosis of acute colchicine myopathy as well as distinguish it from other more common causes of acute flaccid paralysis. We also discuss the possible mechanism of colchicine toxicity and the mounding phenomenon.

Abstract
The appropriate analysis of skeletal muscle tissues is a key element in many diagnostic procedures and can deliver valuable information about the organ that is affected. Although arguably the frequency of muscle biopsy may be declining in certain domains where genetic analysis is now the first line of diagnostic evaluation, it still has an important role in assessment of patients with neuromuscular disorders such as congenital myopathies, muscular dystrophies, metabolic and inflammatory diseases. Here, we have comprehensively discussed the aspects of a modern and fruitful approach to muscle biopsy histopathological studies in rheumatological disorders. We have focussed on the neuromuscular involvement in myositis and its differential diagnoses in both adult and paediatric settings. We have also covered the clinical indications for the biopsy, technical aspects and practical points relevant for the rheumatologists. Finally, we have critically discussed the current and future opportunities that a muscle biopsy may offer and its limitations.

Schwier NC, Cornelio CK, Boylan PM. A systematic review of the drug-drug interaction between statins and colchicine: Patient characteristics, etiologies, and clinical management strategies. Pharmacotherapy 2022; 42:320-333. [PMID: 35175631 DOI: 10.1002/phar.2674] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 02/04/2022] [Accepted: 02/06/2022] [Indexed: 12/20/2022]
Abstract
Colchicine and statins are frequently co-prescribed for prevention and treatment of cardiovascular diseases, auto-inflammatory diseases, and gout. Both are substrates and inhibitors of the cytochrome P-450 (CYP) 3A4 isozyme and P-glycoprotein so that taken together, they represent a clinically significant interaction. Data suggest the interaction may be associated with potentially life-threatening myopathies and rhabdomyolysis. The purposes of this systematic review (SR) were to gather and appraise evidence surrounding the statin-colchicine drug interaction and discuss related risk-mitigation strategies. An electronic literature search was performed. Twenty-one articles met the protocol to be included in the qualitative analysis: 18 case reports/series, 2 retrospective observational cohort studies, and 1 retrospective case-control study. Thirty-eight patients developed an adverse drug event (ADE) receiving statin-colchicine combination therapy; 25 (66%) patients developed myopathy; 10 (26%) patients developed rhabdomyolysis, and three (8%) patients developed neuromyopathy. Over 70% of patients developed ADEs on simvastatin or atorvastatin, and 80% of studies reported moderate-to-high intensity statins. Colchicine dosing varied but ranged between 0.5 to 1.5 mg daily. Sixty-two percent of patients in the case reports/series had comorbid renal disease. Seven studies (33% of all included studies) reported patients taking concomitant interacting medications at the CYP3A4 and/or P-glycoprotein efflux pump. Seventeen studies (81% of all included studies) reported ADEs leading to hospitalization. A multivariate analysis from one case-control study identified risk factors prognosticating myopathy ADEs in patients taking statin-colchicine therapy: comorbid renal disease and/or cirrhosis, colchicine doses 1.2 mg daily or greater, and concomitant interacting medications. Clinicians must be cognizant that the statin-colchicine drug interaction may lead to patient harm and thus should employ risk-mitigation strategies for statin-associated muscle symptoms. Future studies are warranted to validate clinically relevant risk factors that are strongly associated with the complications owing to the statin-colchicine drug interaction.

Abstract
Coronavirus disease 2019 (COVID-19), caused by the late 2019 outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causes a respiratory disease which could put myasthenia gravis (MG) patients at a greater risk of developing severe disease course, since infections and some drugs are a well-recognized trigger of symptom exacerbation in MG patients. Out of ten most commonly used past and present drugs used in COVID-19 treatment, two (quinolone derivatives and azithromycin) are known to worsen MG symptoms, whereas another two (tocilizumab and eculizumab) might have positive effect on MG symptoms. Colchicine, remdesivir, lopinavir, ritonavir and favipiravir seem to be safe to use, while data are insufficient for bamlanivimab, although it is also probably safe to use. Considering MG treatment options in patients infected with SARS-CoV-2, acetylcholine esterase inhibitors are generally safe to use with some preliminary studies even demonstrating therapeutic properties in regard to COVID-19. Corticosteroids are in general safe to use, even recommended in specific circumstances, whereas other immunosuppressive medications (mycophenolate mofetil, azathioprine, cyclosporine, methotrexate) are probably safe to use. The only exception is rituximab since the resulting B cell depletion can lead to more severe COVID-19 disease. Concerning plasmapheresis and intravenous immunoglobulins, both can be used in COVID-19 while taking into consideration thromboembolic properties of the former and hemodynamic disturbances of the latter. As current data suggest, all known COVID-19 vaccines are safe to use in MG patients.

Abstract
A 32-year-old woman attempted suicide by ingesting Gloriosa bulbs and died approximately
2 days later. Toxicological examination revealed a potentially fatal blood concentration
of colchicine (0.096 mg/L). In addition to the increased mitotic figures in the
gastrointestinal mucosa, a unique finding for acute colchicine intoxication, pathological
examination showed microvesicular lipid droplets in the liver, kidney, heart, and
conduction system. Furthermore, central chromatolysis of neurons was observed in the
pontine nucleus, medial accessory olivary nucleus, nucleus of the solitary tract, and
nucleus ambiguus. Grumose degeneration of the cerebellar dentate nucleus was also evident.
These pathological findings may help identify colchicine intoxication, even in the absence
of evidence suggesting ingestion during autopsy. Moreover, pathological changes in the
heart and central nervous system may be associated with the development of serious
complications of acute colchicine intoxication.

Abstract
Glucocorticoids (GCs) are widely used in various autoimmune diseases. Side effects may occur in patients with long-term or high-dose GC usage. Among them, steroid myopathy and osteonecrosis are two severe forms. We report a patient with pemphigus vulgaris on GC-treatment who developed muscle weakness when a cumulative dose of methylprednisolone reached about 20g (14-80mg/d for 2.5 years). Laboratory tests showed slightly elevated lactate dehydrogenase and hydroxybutyrate dehydrogenase. MRI revealed osteonecrosis in the femoral head, distal femur, and proximal tibia of both legs. The biopsy of the right quadriceps revealed atrophy of type II myofiber without leukocyte infiltration, which was suggestive of steroid myopathy. Genotyping of the patient showed 5G/5G genotype of the PAI-1 gene and CC genotype of the ABCB1 gene (C3435T), suggesting she was sensitive to GCs. The patient's lesions were considered to be GC-induced adverse events, which were improved with tapering GC. Therefore, it is important to recognize steroid-induced musculoskeletal side effects and genotyping favors personalized medication.

Abstract
Colchicine-induced myopathy has been described in patients with chronic renal failure and patients who are using a concomitant drug like a statin. However, pure myopathy caused by colchicine has never been reported in Saudi Arabia. A 64-year-old patient received colchicine for his gout arthritis disease and developed upper and lower limb weakness. He had a proximal weakness, and his muscle enzymes were very high. Furthermore, the needle electromyography (EMG) examination showed abundant fibrillations, myotonic discharges, and myopathic motor units. Two weeks after colchicine cessation, his weakness improved dramatically with normalization of creatine kinase (CK) and disappearance of myotonic discharges in the repeated EMG. This is the first case in Saudi Arabia that showed colchicine-induced myositis. The local clinicians' community needs to be aware of this rare side effect, as clinical suspicion is the most important diagnostic clue and the only effective treatment is the termination of colchicine.

Abstract
OBJECTIVES No studies examined the lower extremity-related anaerobic exercise capacity or functional status in adult patients with FMF. METHODS Twenty-four patients with FMF (12 males) and 24 age-sex-matched healthy controls (13 males) were included in the study. Lower extremity-related anaerobic exercise capacity was assessed by using Wingate Anaerobic Test. Lower extremity-related functional status was examined by using 9-Step Stair Climb Test, 10-Repetition Chair Stand Test, and Six-Minute Walking Distance. Muscle strength of hip flexors, hip extensors, knee flexors, and knee extensors were evaluated by using a hand-held dynamometer. RESULTS Patients with FMF had significantly poorer results in all anaerobic exercise capacity parameters and functional status assessments (P < 0.05), except muscle strength measurements (P > 0.05). Both average and peak anaerobic exercise capacities correlated significantly with all muscle strength measurements, 9-Step Stair Climb Test, 10-Repetition Chair Stand Test times, and Six-Minute Walk Distances (P < 0.05) in patients with FMF. CONCLUSION Lower extremity-related anaerobic exercise capacity and functional status seem to be diminished in adult patients with FMF. Evaluating these parameters may be beneficial for planning more appropriate and individualized treatment regimens such as patient education and exercise counselling for patients with FMF.

Abstract
Beside inherited muscle diseases many catabolic conditions such as insulin resistance, malnutrition, cancer growth, aging, infections, chronic inflammatory status, inactivity, obesity are characterized by loss of muscle mass, strength and function. The decrease of muscle quality and quantity increases morbidity, mortality and has a major impact on the quality of life. One of the pathogenetic mechanisms of muscle wasting is the dysregulation of the main protein and organelles quality control system of the cell: the autophagy-lysosome. This review will focus on the role of the autophagy-lysosome system in the different conditions of muscle loss. We will also dissect the signalling pathways that are involved in excessive or defective autophagy regulation. Finally, the state of the art of autophagy modulators that have been used in preclinical or clinical studies to ameliorate muscle mass will be also described.

Abstract
A 74-year-old man with medical history significant for atrial fibrillation, hyperlipidaemia and coronary artery disease on atorvastatin presented to the emergency department with profound weakness. The patient reports he first noticed his weakness 4 weeks after starting colchicine, prescribed for recurrent pericarditis with pericardial effusion, a complication following recent coronary artery bypass grafting. The patient was also on prednisone therapy for presumed post-pericardiotomy syndrome. The weakness involved all four limbs but was more notable in the lower extremities, with preserved sensation and tenderness to palpation. Labs showed an elevated creatinine phosphokinase and serum creatinine consistent with rhabdomyolysis. Discontinuation of the offending medications, including colchicine and atorvastatin, as well as intravenous fluid resuscitation with physical rehabilitation, led to improvement in the patient's symptoms. He was eventually discharged to a rehabilitation facility to continue physical therapy.
