    We present our experiences in the first case of severe suicidal poisoning with 70% ethanol-disinfectant in North Macedonia, in an elderly patient with immunocompromising comorbidities. A 66-year-old unconscious woman was admitted at our clinic, with a history of seropositive rheumatoid arthritis treated with methotrexate. She was in a coma, without signs of serotonin syndrome, recurrent episodes of cardio-respiratory insufficiency under supportive treatment without invasive ventilation, metabolic acidosis, increased D-dimer 3254 ng/mL. The toxicology screening confirmed low benzodiazepines levels and alcoholaemia of 526 mg/dL (5.26 g/L), due to ingestion of 70% ethanol. Considering the decreased biotransformation in the elderly, immunocompromising comorbidities, reports of fatal outcome in poisoned elderly patients with disinfectants under standard fluids supportive protocol, haemodialysis was initiated, with registered associated hypercoagulability which resulted in complete stabilization after 48 h of admission. Treatment protocols of poisoning with ethanol-based disinfectant in the elderly should consider timely performing haemodialysis at lower alcoholaemia levels than recommended.

    The COVID-19 pandemic significantly disrupted global healthcare and societal norms, leading to changes in poisoning patterns, particularly corrosive poisonings (CP). This study aimed to evaluate the impact of the pandemic on CP trends in North Macedonia by comparing observed data from 2020 and 2021 with predicted values (PV) based on a 10-year trend. Methods: A retrospective study was conducted using data from the Poisoning Registry at the PIC, University Clinic of Toxicology, Skopje. Patients with confirmed acute upper gastrointestinal corrosive injuries were included. Results: Between 2010 and 2021, 1,668 CP cases were recorded. While an overall downward trend was observed (y = -6.5x + 181.4, R² = 0.56), CP cases declined by 1.5% in 2020 and by 25.5% in 2021 compared to PV. Female cases decreased by 27.5% in 2021; male cases declined by 16.6% in 2020 and 32.4% in 2021. Adolescent CP increased by 12.8% in 2020 and 80.0% in 2021; cases in those over 75 years rose by 2.5% and 6.2%, respectively. The mean age of CP patients rose by 7.6% in 2020 and 11.0% in 2021. Suicidal poisonings increased by 9.9% in 2021. Disinfectant poisonings rose by 74.5% in 2020, while hydrochloric acid (+6.2%), detergents (+3.4%), and degreasers (+32.0%) increased in 2021. Case fatality ratios rose by 36.2% in 2020 and 44% in 2021. Conclusion: Although the overall number of cases declined, the increased severity, lethality, and demographic shifts—particularly among adolescents and the elderly—highlight the high-risk groups, mental health burden and toxicological risks associated with public health emergencies

    Rhabdomyolysis and Aminotransferase Activity Due to Acute Intoxication With Psychotropic and Chemical Substances
    (Arak University of Medical Sciences, 2023-01)
    ;
    ;
    ;
    ;
    Background: Rhabdomyolysis is caused by the release of enzymes from skeletal muscles into the blood, which leads to systemic complications with diverse etiologies. This study evaluated the serum aminotransferases in patients with rhabdomyolysis following acute intoxication with either psychotropic drugs or other chemical agents. Methods: This study randomly recruited 140 patients suffering from rhabdomyolysis. They were divided into two groups affected by either psychotropic drugs or chemical agents. Rhabdomyolysis was defined as having serum creatine kinase (CK) levels greater than 250 U/L, based on the poisoning severity score. Results: On day 1, the CK/AST correlation was significantly stronger in the psychotropic than the chemical group (P=0.0009). On day 5, patients in the psychotropic group had significantly higher AST (P=0.0138) and ALT (P=0.0129) than those poisoned with other chemicals. The difference in the strength of the CK/ALT correlation between the two groups was insignificant. Between the two groups, the differences between the CK levels and the following serum parameters were insignificant: Alkaline phosphatase; gamma-glutamyl transferase; prothrombin time; total bilirubin; and albumin. Conclusion: The elevated aminotransferases in patients with rhabdomyolysis due to acute psychotropic toxicity might have resulted from the skeletal muscle injury rather than hepatotoxicity. In rhabdomyolysis patients poisoned with other chemicals, the elevated serum aminotransferases are likely due to liver toxicity arising from the consumed substances. These patients are likely to manifest clinically severe long-term multi-organ failure. Intoxications with typical agents, such as herbicides, petroleum distillates, and corrosives were responsible for the rhabdomyolysis in the second group

    Drug-induced toxicity can have a mild to severe clinical presentation as a life-threatening condition. We presented a case with a general vasculitis and severe multi-organ failure in a splenectomised middle-aged woman, which developed after ceftriaxone and metamizole parenteral administration. A middle-aged woman was treated with IV metamizole and ceftriaxone for a fever and soar throat in a local hospital. She had a post traumatic splenectomy 5 years ago. After metamizole, during ceftriaxone administration she felt burning in her face with maculo-papulose rash which started to conflate, spread to whole body and intensively darkened. She was transferred to the University Toxicology Clinic with а hypotension, hypoxemia, generalized necrotic vasculitis with predominant facial distribution. There was increased values for CRP (250 mg/l), WBC (27x10^9/l) and LDH (1867 U/l) during hospitalisation. She also presented anaemia (Er 2.6x10^12/l, Hgb 88 g/l, Hct 0.24), polyserositis-ascites, pleural effusion and mild pericarditis (high sensitive troponin 107 ng/l), acute pancreatitis (amylase 1048 U/l, lipase 881 U/l), hepatomegaly, acute kidney injury (BUN 36.5 mmol/l, creatinine 528 μmol/l, oliguria), disseminated intravascular coagulation (Plt 23x10^9/l, DD 7658ng/ml, PT 56 sec, aPTT 120 sec), vitreous haemorrhage of the right eye and rhabdomyolysis, CPK 428U/l. Microbiological findings were negative. Immunoserology showed positive p-ANCA. The acute renal failure, ascites and pleural effusions resolved under methylprednisolone, meropenem, LMWH, haemodialysis and symptomatic therapy, with normalization of laboratory parameters. A skin biopsy finding was inconclusive. After 25 days, rheumatologist recommended mycophenolate mofetil PO. She was asymptomatic with prednisolone and mycophenolate mofetil therapy during following two years and maintained stable after their discontinuation. Drug-induced toxicity have potential to induce a severe multiorgan failure with life-threatening complications. Splenectomy may be studied as a potentially risk factor for immunomodulated response to drugs and drugs interactions, especially during infections.

    Objective: Lithium toxicity can be acute or chronic and the effects may be disabling or life-threatening. We present a case with lithium toxicity due to chronic treatment. A 63-year-old man was brought to the University Clinic for Toxicology in Skopje with a 2-day history of confusion, slurred speech, nausea, vomiting, loss of appetite, and weakness. His medical history included bipolar disorder, which had been diagnosed 17 years previously, and since then he has been on lithium therapy 900mg orally daily. The patient had not had regular check-ups for several years. His oral intake was markedly reduced, for the last five days. On admission, he was severely dehydrated. Vital signs included a blood pressure of 110/50 mm Hg a pulse rate of 49 beats/min, and oxygen saturation of 97%. Investigations revealed serum lithium level 3.43 (normal 0.5–1.5 mmol/L) suggesting lithium toxicity, creatinine level 168 umol/L, urea 15 mmol/L alkaline phosphatase 182 U/L calcium 2.34 mmol/L. A 12-lead electrocardiogram showed normal sinus rhythm, precordial T-wave inversions, and a prolonged QTc interval of 533 ms. After one treatment of hemodialysis lasting two and half hours, his lithium level dropped to 2,04 mmol/L and creatinine to126 μmol/L. No intracranial abnormality was seen on a computed tomography scan of the head. Further investigation revealed parathyroid hormone 170 pg/ml, ionized calcium 1.43 mmol/L. Treatment management included volume replacement for dehydration. Abdominal computed tomography was with orderly finding. All investigations were at the normal therapeutic range before discharge and sent to the psychiatrist on the eleventh day. Conclusion: Patients on long-term lithium therapy with no regular check-ups are at high risk of developing toxicity. The toxicity was due to intravascular volume depletion, and impaired lithium excretion. The patients should be monitored frequently for all potential endocrine, renal, and neurological disorders.

    Initial studies on impaired glucose-insulin homeostasis in heroin dependents have not defined the impact of concomitant hepatitis C infection (HCV), which has been strongly associated with the development of insulin resistanceand metabolic syndrome (MS). The aim of our study was to evaluate the association of heroin dependence with glucose-insulin homeostasis and MS in heroin dependents with HCV seronegativity. Materials and methods: The study was prospective and cross-sectional, including 160 heroin dependents compared to a control group of 60 participants.MS was diagnosed using International Diabetes Federation criteria. The homeostatic model assessment for insulin resistance (HOMA-IR) and pancreatic β-cell function (HOMA-%B) were used for assessing insulin resistance and β-cell function of pancreas. Results: MS was detected in 9.32% of heroin addicts. Heroin dependents with MS compared to dependents without MS were older, had higher BMI, waist circumference and significantly higher systolic and diastolic blood pressure, increased triglycerides (F=8.233, df=2, p<0.001), apoB (F=8.154, df=2, p=0.001), and reduced HDL-C (F=25.926, df=2, p<0.001) and apoA-I (F=16.406, df=2, p<0.001), significantly increased inuslinemia (F=4.928, df=2, p<0.05), insulin resistance-HOMA-IR (F=4,928, df=2, p<0,05) and insignificantly increased pancreatic β-cell function (194.66 ±224.05) (F=2.461, df=2, p>0.05). Conclusions: Insulin resistance and МS, independent of HCV, was also registered in heroin dependence. Timely recognition will enable more successful treatment of comorbidities and illicit drug dependence.

    We present a case with p-ANCA positive general vasculitis and severe multi-organ injury in a splenectomised patient, which developed during ceftriaxone and metamizole administration for treatment of upper respiratory infection. Case report: A middle-aged woman with 400C fever and sore throat got a treatment with IV metamizole and ceftriaxone in a local hospital. She had a post- traumatic splenectomy 5 years ago. After metamizole, during ceftriaxone administration she felt burning in her face, developing red rush which spread over the face and darkened, later extended to her palms and feet. After visiting several clinics, she was referred finally to the University Clinic for Toxicology in Skopje. On admission, she had hypotension, hypoxemia, livid oro-pharynx, necrotic vasculitis with predominant facial distribution and unpalpable purpura on the extremities. The examinations revealed high levels of inflammatory biomarkers, anaemia, polyserositis, acute pancreatitis, hepatomegaly, acute kidney injury, disseminated intravascular coagulation, right eye vitreous haemorrhage and rhabdomyolysis. Microbiological investigations were negative. Immuno-serology showed positive p-ANCA. The acute renal failure and polyserositis resolved under methylprednisolone, meropenem, furosemide, low molecular weight heparin, fresh frozen plasma, and other symptomatic therapy, which decreased the inflammatory biomarkers, but DIC with thrombocytopenia persisted. A skin biopsy finding was inconclusive. After 25 days, the rheumatologist recommended mycophenolate mofetil with prednisolone peroral therapy during two years that resulted in stabilizing the vasculitis. The patient maintained stable after therapy discontinuation. Conclusions: Drug-induced vasculitis has the potential to induce a severe multi-organ injury with life-threatening complications. Mycophenolate mofetil procured a safe and successful treatment of drug-induced vasculitis. Splenectomy may be a potential risk factor for immunomodulated response to drugs and drugs interactions, especially during infections.

    ;
    Heat stroke is a set of symptoms that include a severe rise of body temperature that is usually but not always higher than 40ºC. Clin- ically, it is characterized by central nervous system dysfunction such as ataxia, delirium or cramps, in conditions of exposure to hot weather or strenuous physical exertion. We presented a 46-year-old male athlete who collapsed during a half marathon after running 20 km and 640 m in 2 hours and 2 minutes. He was brought to the clinic in an unconscious state febrile 38.6ºC with fasciculations, convulsions, hypotensive, tachycardic. During hospitalization with rhabdomyolysis and hypoxic hepatitis. It is crucial to recognize the clinical symptoms and signs in the acute phase of heat stroke and in areas with temperate continental climate, to begin timely treatment, to reduce mortality. Complications of heat stroke need to be diagnosed, appropriate treatment provided, to improve the prognosis of these conditions.
