Hydroxychloroquine (HCQ) induced cardiotoxicity is a rare diagnosis and is often associated with chronic use of the medication. It has been shown that chronic HCQ use is associated with a drug-induced cardiomyopathy mainly driven by acquired lysosomal storage defects leading to hypertrophy and conduction abnormalities. As the only proven treatment is the discontinuation of the offending agent, prompt recognition is required to avoid further exposure to the drug and potential progression of disease. History, physical examination and advanced imaging modalities are useful diagnostic tools, but more invasive testing with an endomyocardial biopsy is required for definitive diagnosis. We present a descriptive case series of ten patients that were diagnosed with biopsy proven HCQ cardiotoxicity.

Introduction: Metabolic Dysfunction-associated Liver Disease (MASLD) represents a spectrum of conditions from simple fat accumulation to non-alcoholic steatohepatitis. The possible role of the intestinal microbiome on MASLD development has been in focus. Our study aimed to examine the effects of synbiotics on the liver steatosis, inflammation, and stool microbiome.

Methods: A double-blind, placebo-controlled study was conducted involving 84 MASLD patients, defined by an elastometric attenuation coefficient (ATT) greater than 0.63 dB/cm/MHz with an alanine aminotransferase level above 40 U/L for men and 35 U/L for women. The patients were divided into an intervention group treated with a synbiotic with 64x10⁹ CFU of Lactobacillus and Bifidobacterium and 6.4g of inulin and a control group treated with a placebo.

Results: Using synbiotics for 12 weeks significantly decreased liver steatosis (ΔATT -0.006±0.023 vs -0.016±0.021 dB/cm/MHz, p=0.046). The group of patients treated with synbiotics showed a significant decrease in the level of high-sensitive C-reactive protein (Δhs-CRP 0 vs -0.7 mg/L, p≤0.001). Synbiotics enriched the microbiome of patients in the intervention group with the genera Lactobacillus, Bifidobacterium, Faecalibacterium, and Streptococcus, by 81%, 55%, 51%, and 40%, respectively, with a reduction of Ruminococcus and Enterobacterium by 35% and 40%. Synbiotic treatment significantly shortened the gut transition time (ΔGTT -5h vs. -10h, p=0.031).

Conclusion: Synbiotics could be an effective and safe option that could have place in MASLD treatment.

Introduction: Stroke is a leading cause of mortality worldwide and a major cause of disability having a high burden on patients, society, and caregiving systems. This study was conducted to investigate the presence of clusters of in-hospital patients with acute stroke based on demographic and clinical data. Cluster analysis reveals patterns in patient characteristics without requiring knowledge of a predefined patient category or assumptions about likely groupings within the data.

Methods: We performed a secondary analysis of open-access anonymized data from patients with acute stroke admitted to a hospital between December 2019 to June 2021. In total, 216 patients (78; 36.1% men) were included in the analytical dataset with a mean (SD) age of 60.3 (14.4). Many demographic and clinical features were included in the analysis and the Barthel Index on discharge was used for comparing the functional recovery of the identified clusters.

Results: Hierarchical clustering based on the principal components identified two clusters of 109 and 107 patients. The clusters were different in the Barthel Index scores on discharge with the mean (SD) of 39.3 (29.3) versus 62.6 (29.4); t (213.87) = -5.818, P <0.001, Cohen's d (95%CI) = -0.80 (-1.07, -0.52). A logistic model showed that age, systolic blood pressure, pulse rate, D-dimer blood level, low-density lipoprotein, hemoglobin, creatinine concentration, the National Institute of Health Stroke Scale value, and the Barthel Index scores on admission were significant predictors of cluster profiles (all P ≤0.029).

Conclusion: There are two clusters in hospitalized patients with acute stroke with significantly different functional recovery. This allows prognostic grouping of hospitalized acute stroke patients for prioritization of care or resource allocation. The clusters can be recognized using easily measured demographic and clinical features.

Background and aims: Thyroid function abnormalities and thyroid autoantibodies have previously been described in rheumatoid arthirits (RA) with limited data. In some studies, a relationship was found between thyroid autoantibodies and RA disease activity. However, there are not strong studies in the literature indicating the relationship between thyroid diseases and RA. The aim of this study was to determine the frequency of hypothyroidism and to investigate the relationship between thyroid hormone levels, autoantibodies and disease activity in patients with rheumatoid arthritis (RA). Methods : 1017 patients with the diagnosis of RA were recruited. This observational study was conducted between January 2014 and July 2015. Demographic variables were recorded. Anti-nuclear antibodies (ANA), anti-cyclic citrulli-nated peptide antibody (anti-CCP), Rheumatoid Factor (RF), C reactive protein (CRP), Erythrocyte Sedimentation Rate (ESR), thyroid stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), anti-microsomal antibody (anti-TPO )and anti-thyroglobulin antibody (anti-TG) were determined. Visual analog score and Disease Activiy Score 28 (DAS-28) ESR and DAS-28 CRP were recorded. The relationship between thyroid hormone levels and thyroid antibodies and disease activity parameters were determined. Results: 98 (%9,7) patients had hypothyroidism and 61 (%6) patients had hyperthyroidism. 210 (20,7%) patients with RA was positive for TPOAb and 165(16,3%) for anti-TG. Positive correlation was detected between anti-TPO positivity and anti-CCP levels (p:0.005, r:0,274). In anti-TG antibody positive patients, there was a significant positive correlation of thyroid hormone levels with CRP and DAS 28-CRP (p:0.01, r:0,120; p:0.01, r:0,169). Conclusion: Thyroid autoantibodies were found to be positive in 16-21% of patients with RA. Though hypothyroidism is not very frequent in RA patients, autoimmune thyroid disease is quite common, which may be related to disease activity.

Factor XI is a zymogen with an important role in the coagulation cascade. It is activated by FXII, thrombin and or it can be autoactivated. It has a prothrombotic effect after being activated by thrombin, but also through its antifibrinolytic action, stabilizing the formed clot. Hereditary deficiency of FXI causes haemophilia C - a disease manifested by an usually provoked, small to moderate mucosal bleeding. People with severe FXI deficiency have a low risk of thrombotic events. Conversely, increased FXI values have been found to be associated with increased risk of venous thromboembolism and ischemic stroke. Lowering serum FXI levels has become a treatment target for the prevention of thrombotic events. New pharmacological agents - FXI inhibitors - have been investigated in phase II clinical trials, with promising results in terms of efficacy and safety in the prevention of thrombotic events. FXI inhibitors are emerging as new anticoagulant agents with broad indication prospects beyond direct oral anticoagulants and vitamin K antagonists.

Perioperative acid-base disturbance could be informative regarding the possible slow graft function (SGF) or delayed graft function (DGF) development. There is a lack of data regarding the relationship between perioperative acid-base parameters and graft dysfunction in kidney transplant (KT) recipients. We aim to determine the incidence of graft dysfunction types and the association between them and acid-base parameters. We performed a prospective, cohort study on 54 adults, KT recipients, between 1^st of January 2019 and 31^st of December 2019. Graft function was defined and classified in three categories: immediate graft function (IGF) (serum creatinine < 3 mg/dL at day 5 after KT), SGF (serum creatinine ≥ 3mg/dL at day 5 or ≥ 2.5mg dL at day 7 after KT) and DGF (the need for at least one dialysis treatment in the first week after kidney transplantation). Among the 54 KT recipients, the incidence of SGF and DGF was 13% and 11.1%, respectively. SGF was significantly associated with lower intraoperative pH (7.26± 0.05 vs 7.35± 0.06, p= 0.004), preoperative and intraoperative base excess (BE) [-7.0 (-10.0 ߝ -6.0) vs -3.4 (-7.8 ߝ - 2.1) mmol/L, p= 0.04 and -10.3 (-11.0 ߝ -9.1) vs -4.0 (-6.3 ߝ - 3.0) mmol/L, p= 0.002, respectively] and serum bicarbonate (HCO3^-) (16.0± 2.7 vs 19.3± 3.4 mmol/L, p= 0.01 and 14.1± 1.9 vs 18.8± 3.2 mmol/L, p= 0.002 respectively), compared to IGF. DGF was significantly associated with lower intraoperative values of pH (7.27± 0.05 vs 7.35± 0.06, p= 0.003), BE [-7.1 (-10.9 ߝ -6.1) vs -4.0 (-6.3 ߝ - 3.0) mmol/L, p= 0.02] and HCO3^- (15.9± 2.4 vs 18.8± 3.2 mmol/L, p=0.02) compared to IGF. No differences were observed between SGF and DGF patients in any of the perioperative acid-base parameters. In conclusion we found that kidney graft dysfunction types are associated with perioperative acid-base parameters and perioperative metabolic acidosis could provide important information to predict SGF or DGF occurrence.

Background: Acute Kidney Injury (AKI) is one of the most important causes of in-hospital mortality. The global burden of AKI continues to rise without a marked reduction in mortality. As such, the use of renal replacement therapy (RRT) forms an integral part of AKI management, especially in critically ill patients. There has been much debate over the preferred modality of RRT between continuous, intermittent and intermediate modes. While there is abundant data from Europe and North America, data from tropical countries especially the Indian subcontinent is sparse. Our study aims to provide an Indian perspective on the dialytic management of tropical AKI in a tertiary care hospital setup.

Methods: 90 patients of AKI, 30 each undergoing Continuous Renal Replacement Therapy (CRRT), Intermittent Hemodialysis (IHD) and SLED (Sustained Low-Efficiency Dialysis) were included in this prospective cohort study. At the end of 28 days of hospital stay, discharge or death, outcome measures were ascertained which included mortality, duration of hospital stay, recovery of renal function and requirement of RRT after discharge. In addition median of the net change of renal parameters was also computed across the three groups. Lastly, Kaplan Meier analysis was performed to assess the probability of survival with the use of each modality of RRT.

Results: There was no significant difference in the primary outcome of mortality between the three cohorts (p=0.27). However, CRRT was associated with greater renal recovery (p= 0.015) than IHD or SLED. On the other hand, SLED and IHD were associated with a greater net reduction in blood urea (p=0.004) and serum creatinine (p=0.053).

Conclusion: CRRT, IHD and SLED are all complementary to each other and are viable options in the treatment of AKI patients.

Clopidogrel is a widely prescribed prodrug with antithrombotic activity that functions by irreversibly inhibiting the P2Y12 receptors on platelets; nevertheless, drug-induced eosinophilia from this drug is rarely reported. An 81-year-old man was diagnosed with cerebral infarction 2 months earlier and was admitted to our hospital with rash, fever, wheezing, and stomach discomfort after being initiated with clopidogrel treatment. Based on his medical history, chest CT, and gastroscopy, we diagnosed him with clopidogrel-induced hypereosinophilic syndrome. After discontinuation of clopidogrel, the eosinophilia and symptoms improved. In cases of drug-induced eosinophilia, it is important to obtain a detailed medical history.

Calcium pyrophosphate crystal deposition disease (CPPD), also known as pseudogout, with spinal involvement, is associated with clinical manifestations of acute nerve compression or chronic spinal stenosis. Precipitation of crystals of calcium pyrophosphate dihydrate in connective tissues can lead to acute inflammatory arthritis, degenerative chronic arthropathies, and radiographic evidence of cartilage calcification. We present a case of an 87-year-old woman, with unstudied chronic polyarthralgia and symptomatic orthostatic hypotension. It were documented acute calcium pyrophosphate deposition wrist arthritis, and cervical CT and MRI was suggestive of spinal involvement of CPPD. Workup excluded other causes of OH. Surgical approach could be indicated to minimize the symptoms, but it was contra-indicated due to the patient's performance status, so histological diagnosis was not possible. Muscle atrophy played an important part in the rapid progression of this insidious chronic disease. Conservative and symptomatic treatment achieve scarce short-term clinical improvement. Spinal involvement of CPPD was thought to be rare but recent studies show a higher prevalence than expected. We call for attention to the extent of structural changes that may occur when not early diagnosed nor treated. High clinical suspicion is required and this is, to our knowledge, the first report of orthostatic hypotension as a presentation of CPPD.
