Earthquake victims in focus: a cross-sectional examination of trauma and management in intensive care unit.

BACKGROUND: After the Kahramanmaras earthquake of February 6, 2023, the disaster of the century, a significant number of victims were admitted to intensive care units (ICUs). In this study, we aimed to share the characteristics and management of critical earthquake victims and shed light on our experiences as intensivists in future earthquakes. METHODS: The study included 62 earthquake victims in two tertiary ICUs. Demographic characteristics, laboratory findings, clinical characteristics, trauma and disease severity scores, treatments administered to patients, and the clinical course of the patients were recorded retrospectively. The patients were divided into two groups, survivors and nonsurvivors, according to 7-day mortality and into two groups according to the duration of their stay under the rubble: those who remained under the rubble for 72 hours or less and those who remained under the rubble for more than 72 hours. A receiver operating characteristic (ROC) curve analysis was used to determine the best cutoff value for the 'Circulation, Respiration, Abdomen, Motor, and Speech' (CRAMS) score. RESULTS: The median age of the 62 patients included in the study was 35.5 (23-53) years. The median length of stay under the rubble for the patients was 30.5 (12-64.5) hours. The patient was transferred to the ward with a maximum duration of 222 hours under the rubble. The limb (75.8%) was the most common location of trauma in patients admitted to the ICU. Crush syndrome developed in 96.8% of the patients. There was a positive correlation between the development of acute kidney injury (AKI) and myoglobin, serum lactate, and uric acid levels (r = 0.372, p = 0.003; r = 0.307, p = 0.016; r = 0.428, p = 0.001, respectively). The best cutoff of the CRAMS score to predict in-7-day mortality was < 4.5 with 0.94 area under the curve (AUC); application of this threshold resulted in 75% sensitivity and 96.3% specificity. CONCLUSION: Search and rescue operations should continue for at least ten days after an earthquake. The CRAMS score can be used to assess trauma severity and predict mortality in critically ill earthquake victims.

Vaccination status of COVID-19 patients followed up in the ICU in a country with heterologous vaccination policy: A multicenter national study in Turkey.

OBJECTIVE: Vaccination against severe acute respiratory syndrome coronavirus-2 (SARS-2) prevents the development of serious diseases has been shown in many studies. However, the effect of vaccination on outcomes in COVID-19 patients requiring intensive care is not clear. METHODS: This is a retrospective multicenter study conducted in 17 intensive care unit (ICU) in Turkey between January 1, 2021, and December 31, 2021. Patients aged 18 years and older who were diagnosed with COVID-19 and followed in ICU were included in the study. Patients who have never been vaccinated and patients who have been vaccinated with a single dose were considered unvaccinated. Logistic regression models were fit for the two outcomes (28-day mortality and in-hospital mortality). RESULTS: A total of 2968 patients were included final analysis. The most of patients followed in the ICU during the study period were unvaccinated (58.5%). Vaccinated patients were older, had higher Charlson comorbidity index (CCI), and had higher APACHE-2 scores than unvaccinated patients. Risk for 28-day mortality and in-hospital mortality was similar in across the year both vaccinated and unvaccinated patients. However, risk for in-hospital mortality and 28-day mortality was higher in the unvaccinated patients in quarter 4 adjusted for gender and CCI (OR: 1.45, 95% CI: 1.06-1.99 and OR: 1.42, 95% CI: 1.03-1.96, respectively) compared to the vaccinated group. CONCLUSION: Despite effective vaccination, fully vaccinated patients may be admitted to ICU because of disease severity. Unvaccinated patients were younger and had fewer comorbid conditions. Unvaccinated patients have an increased risk of 28-day mortality when adjusted for gender and CCI.

The Diagnostic profile and clinical course of patients with rheumatic diseases in the medical intensive care unit.

Background/aim: Immunosuppressive and immunomodulatory treatments developed in recent years as a result of a better understanding of the pathophysiology of systemic rheumatic diseases (SRDs) improve the prognosis. Despite medical advances, individuals with SRDs at any stage may require intensive care and have a high mortality rate. The aim of this study was to investigate the demographic and clinical characteristics of patients with rheumatic diseases admitted to the intensive care unit (ICU), and the factors associated with the risk of mortality. Materials and methods: This was a retrospective, cross-sectional study that included patients with rheumatic diseases in the medical ICU. Factors of ICU 28-day mortality were identified by multiple-variable logistic analysis. Results: A total of 127 patients with SRDs admitted to the medical ICU were enrolled. Systemic lupus erythematosus (SLE) (32.3%) was the most common diagnosis of SRDs in patients admitted to the ICU. The reasons for admission to the ICU were combined infection and primary SRD flare-up (35.4%), primary SRD flare-up (22%), SRD-unrelated reasons (22%), infection (17.3%), drug side effects (3.9%), and SRD-related complications (0.8%). The most common organ dysfunctions before (49.6%) and during (77.2%) admission to ICU were in the respiratory system. The 28-day mortality was 78 (61.4%). While the maximum procalcitonin, serum lactate, and blood urea nitrogen (BUN) levels were higher in the nonsurvivor group, the platelet and serum albumin levels were statistically significantly lower than those in the survivor group (p < 0.05). Acute respiratory failure (ARF), the presence of septic shock, the need for invasive mechanical ventilation (IMV), BUN level, and low platelet-lymphocyte ratio (PLR) were significant in the final multiple-variable model. Conclusion: Significant predictors of mortality in patients with rheumatic diseases may include ARF, septic shock, the need for IMV, and high BUN and low PLR levels.

Apheresis in patients with sepsis: A multicenter retrospective study.

BACKGROUND AND OBJECTIVES: To consider the effectiveness of apheresis, which is a supportive treatment method, in sepsis. MATERIALS AND METHODS: A hundred and eleven adults with sepsis or septic shock were included in this retrospective study. The demographic characteristics of the patients, the focus and source of infection causing sepsis or septic shock, characteristics of the pathogen, Acute Physiological and Chronic Health Assessment (APACHE) II score, routine laboratory values, which apheresis method was used, the characteristics of the replacement fluids used during the apheresis procedure, the number of apheresis procedures, complications related to the apheresis procedure, the follow-up time after the procedure, and mortality were recorded. The primary outcome was 28-day mortality. RESULTS: Sixty-nine (62.2 %) of the patients were male. The mean age of the patients was 47.7 ± 18.6 years. The most common source of sepsis was hospital-acquired (79.3 %), the most common pathogen causing sepsis was gram-negative bacteria (41.4 %), and the most common infection site was the respiratory tract (58.7 %). The median APACHE II score was 19 (13-24). 92 (82.9 %) of the patients had septic shock. Theropeutic plasma exchange (TPE) was performed in 11.7 % of the patients and immunoabsorbtion IA in 88.3 %. The median number of sessions was 3 (3-5). No procedure-related fatal complication was observed in the study. While 28-day mortality was 61.3 % in all patients, when the mortality according to the apheresis procedures was examined, it was 11.3 % and 88.2 % in the patients who underwent TPE and IA, respectively. The most common cause of mortality was multiorgan failure. CONCLUSIONS: Apheresis in sepsis can be considered as a salvage treatment. The indication for apheresis in sepsis is still at the level of patient-based individualized decision in line with the studies done so far, including our study. However, there is a need for a multicenter randomized controlled study with a large number of patients in order to give positive or negative recommendations about its effectiveness.

Evaluation of whole blood thiamine pyrophosphate concentrations in critically ill patients receiving chronic diuretic therapy prior to admission to Turkish intensive care units: A pragmatic, multicenter, prospective study.

BACKGROUND/OBJECTIVES: Thiamine plays a pivotal role in energy metabolism. The aim of the study was to determine serial whole blood TPP concentrations in critically ill patients receiving chronic diuretic treatment before ICU admission and to correlate TPP levels with clinically determined serum phosphorus concentrations. SUBJECTS/METHODS: This observational study was performed in 15 medical ICUs. Serial whole blood TPP concentrations were measured by HPLC at baseline and at days 2, 5 and 10 after ICU admission. RESULTS: A total of 221 participants were included. Of these, 18% demonstrated low TPP concentrations upon admission to the ICU, while 26% of participants demonstrated low levels at some point during the 10-day study period. Hypophosphatemia was detected in 30% of participants at some point during the 10-day period of observation. TPP levels were significantly and positively correlated with serum phosphorus levels at each time point (P < 0.05 for all). CONCLUSIONS: Our results show that 18% of these critically ill patients exhibited low whole blood TPP concentrations on ICU admission and 26% had low levels during the initial 10 ICU days, respectively. The modest correlation between TPP and phosphorus concentrations suggests a possible association due to a refeeding effect in ICU patients requiring chronic diuretic therapy.

Nailfold Videocapillaroscopy in Patients with COVID-19-associated Pneumonia in Intensive Care Units.

OBJECTIVE: To compare patients with COVID-19 in intensive care units (ICUs) to healthy controls using nailfold videocapillaroscopy (NVC), offering standardised findings about micro-circulation. STUDY DESIGN: A descriptive, cross-sectional study. PLACE AND DURATION OF STUDY: Medical Intensive Care Unit, Kayseri City Education and Research Hospital, Kayseri, Turkey between January and May 2021. METHODOLOGY: The NVC parameters-capillary morphology, loop diameter, capillary density, dilated capillaries, giant capillaries, avascular areas, microaneurysms, and micro-hemorrhages of 32 patients with COVID-19 and 29 controls were recorded. RESULTS: The most common capillary morphology in the COVID-19 group (18/32, 56.2%) was serpentine, which also characterised some (6/29, 20.7%) patients in the non-COVID-19 group (p <0.001). The median capillary loop diameter was 77.78 ± 3.63 µm in the COVID-19 group and 71.67 ± 2.19 µm in the non-COVID-19 group (p=0.030). Mean capillary density was 6.41 ± 1.21/1 mm in the COVID-19 group and 8.55 ± 1.12/1 mm in the non-COVID-19 group (p <0.001). The COVID-19 group had significantly more enlarged capillaries (p = 0.001), giant capillaries (p = 0.025), avascular areas (p = 0.028), micro-aneurysms (p <0.001), and micro-hemorrhages (p = 0.011). Mean capillary density was 5.50 ± 0.19/1 mm among deceased patients with COVID-19, but 6.71 ± 0.25/1 mm among survivors (p = 0.011). CONCLUSION: NVC findings differed between patients with COVID-19 and controls, and capillary density was less among deceased patients with COVID-19 than survivors. KEY WORDS: Capillaries, COVID-19, Intensive care unit, Micro-circulation, Nailfold videocapillaroscopy.

A loxoscelism case received therapeutic apheresis and hyperbaric oxygen therapy.

Loxosceles reclusa (L.reclusa) is known to bite humans, and its venom includes several enzymes that cause clinical symptoms. Loxoscelism, a condition due to being bitten by Loxosceles spiders, commonly known as recluses, can involve a range of clinical conditions, from local cutaneous lesions to severe systemic involvement. The diagnosis of loxoscelism is usually made by anamnesis and clinical findings. Magnetic resonance imaging is recommended for patients at high risk of necrotizing fasciitis. Treatment modalities are still controversial and there is no standardized treatment approach. Reported here, our case of loxoscelism involved a 24-year-old man presenting with a Loxosceles spider bite, dermonecrotic lesion, vomiting, diarrhea, acute renal injury, and rhabdomyolysis, who was successfully treated with hyperbaric oxygen therapy, therapeutic apheresis, hemodialysis, wound debridement, and cutaneous autografting. Early diagnosis and multidisciplinary approach can be life-saving in spider bites that can cause systemic involvement. Loxoscelism should be considered in patients with skin necrosis, acute renal injury, and rhabdomyolysis.

Seasonal Association of Immune Thrombocytopenia in Adults.

BACKGROUND: Immune thrombocytopenia (ITP) is an autoimmune disorder. It is characterized by thrombocytopenia due to thrombocyte destruction mediated by autoantibodies; however, cytotoxic and defective regulatory T-lymphocytes play an important role in its pathogenesis. While childhood ITP is usually acute, self-limiting and generally seasonal in nature, ITP in adults is usually chronic; its relation with seasons has not been studied. AIMS: We investigated whether months and/or seasons have triggering roles in adults with ITP. STUDY DESIGN: Descriptive study. METHODS: A retrospective case review of adult patients with primary ITP diagnosed at various University Hospitals in cities where Mediterranean climate is seen was performed. Demographic data, date of referral and treatments were recorded. Corticosteroid-resistant, chronic and refractory cases were determined. Relation between sex, corticosteroid-resistant, chronic and refractory ITP with the seasons was also investigated. RESULTS: The study included 165 patients (124 female, mean age=42.8±16.6). Most cases of primary ITP were diagnosed in the spring (p=0.015). Rates of patients diagnosed according to the seasons were as follows: 35.8% in spring, 23% in summer, 20.6% in fall, and 20.6% in winter. With respect to months, the majority of cases occurred in May (18.2%). Time of diagnosis according to the seasons did not differ between genders (p=0.699). First-line treatment was corticosteroids in 97.3%, but 35% of the cases were corticosteroid-resistant. Steroid-resistant patients were mostly diagnosed in the spring (52.1%) (p=0.001). ITP was chronic in 52.7% of the patients and they were also diagnosed mostly in the spring (62.7%) (p=0.149). CONCLUSION: This is the first study showing seasonal association of ITP in adults and we have observed that ITP in adults is mostly diagnosed in the spring. The reason why more patients are diagnosed in the spring may be due to the existence of atmospheric pollens reaching maximum levels in the spring in places where a Mediterranean climate is seen.
