Septic shock, hyperferritinemic syndrome, and multiple organ dysfunction without respiratory failure in a patient with disseminated histoplasmosis and advanced HIV disease

ABSTRACT AIDS-related disseminated histoplasmosis (DH) can cause septic shock and multiorgan dysfunction with mortality rates of up to 80%. A 41-year-old male presented with fever, fatigue, weight loss, disseminated skin lesions, low urine output, and mental confusion. Three weeks before admission, the patient was diagnosed with HIV infection, but antiretroviral therapy (ART) was not initiated. On day 1 of admission, sepsis with multiorgan dysfunction (acute renal failure, metabolic acidosis, hepatic failure, and coagulopathy) was identified. A chest computed tomography showed unspecific findings. Yeasts suggestive of Histoplasma spp. were observed in a routine peripheral blood smear. On day 2, the patient was transferred to the ICU, where his clinical condition progressed with reduced level of consciousness, hyperferritinemia, and refractory septic shock, requiring high doses of vasopressors, corticosteroids, mechanical ventilation, and hemodialysis. Amphotericin B deoxycholate was initiated. On day 3, yeasts suggestive of Histoplasma spp. were observed in the bone marrow. On day 10, ART was initiated. On day 28, samples of peripheral blood and bone marrow cultures revealed Histoplasma spp. The patient stayed in the ICU for 32 days, completing three weeks of intravenous antifungal therapy. After progressive clinical and laboratory improvement, the patient was discharged from the hospital on oral itraconazole, trimethoprim-sulfamethoxazole, and ART. This case highlights the inclusion of DH in the differential diagnosis of patients with advanced HIV disease, septic shock and multiorgan dysfunction but without respiratory failure. In addition, it provides early in-hospital diagnosis and treatment and comprehensive management in the ICU as determining factors for a good outcome.

Pregnancy emerged thrombocytopenia: maternal and fetal outcome

Background: A low platelet count is often an incidental finding in pregnancy. It can be an indicator of a severe systemic disorder requiring emergent maternal and fetal care or can just be unique to pregnancy with no harm to mother or fetus. Physiological decrease in platelet count is seen in pregnancy due to hemodilution and hypercoagulating state, though the exact pathophysiology is still unclear.Methods: It is a prospective observational study done in a tertiary care centre.Results: In about 11,258 cases screened 46 patients had thrombocytopenia (0.4%). The commonest etiology is found to be gestational thrombocytopenia (n=21, 45.6%) followed by preeclampsia/ eclampsia/ HELLP (haemolysis, elevated liver enzymes, low platelet count) syndrome (n=19, 41.3%). Only one patient had immune thrombocytopenic purpura (ITP) and 7 (15.3%) were associated with amplified fragment length polymorphism (AFLP). Maximum of them (n=19, 41.3%) underwent spontaneous vaginal delivery. 4 patients (8.6%) had postpartum haemorrhage, 6 (13.04%) had ceserean section wound infection, 4 (8.6%) had disseminated intravascular coagulation (DIC) and 4 (8.6%) had multiorgan failure. 13 patients (28.3%) had platelet count between 40 to 60 thousand per cumm, 11 (23.9%) had between 60 to 80 thousand per cumm, 10 (21.7%) had between 80,000 to 1 lakh and none had their platelet count less than 20,000 per cumm.Conclusions: Gestational thrombocytopenia is not a preventable condition. It is an incidental finding in pregnancy. With strict vigilance during intrapartum and postpartum period, even without any treatment proper for the same, the maternal and fetal outcome is found to be good.

Falla multiorgánica y desenlaces clínicos en pacientes sépticos con síndrome eutiroideo enfermo / Multiorgan failure and clinical outcomes in septic patients with euthyroid sick syndrome / Insuficiência de múltiplos órgãos e resultados clínicos em pacientes sépticos com síndrome do doente eutireoidiano

Resumen: Introducción: La prevalencia del síndrome eutiroideo enfermo en pacientes con sepsis es aproximadamente de 60%; existe poca información sobre su correlación con falla multiorgánica. Objetivo: Estimar la prevalencia del síndrome eutiroideo enfermo (SEE) y correlacionar con la presencia de fallas orgánicas específicas y puntajes de gravedad y desenlaces clínicos. Métodos: Se incluyeron pacientes con diagnóstico de sepsis en una unidad de cuidados críticos durante el periodo comprendido de marzo de 2014 a febrero de 2016; se tomaron variables clínicas y estudios de laboratorio que incluían perfil tiroideo en todos los pacientes. Análisis estadístico: Estadística descriptiva con medidas de frecuencia, tendencia central y dispersión. Se realizaron análisis de supervivencia con modelos de regresión de Cox y curvas de Kaplan-Meier para mortalidad; razones de riesgo e intervalos de confianza de 95%. Un error alfa ajustado menor de 5% a dos colas fue considerado significativo. Se usó la paquetería estadística STATA SE versión 11.1. Resultados: Se incluyó un total de 90 pacientes, 51.1% de sexo femenino, con edad de 71 ± 14.15 años, IMC al ingreso a la UCI de 24.94 ± 5.07 kg/m2. La prevalencia global de SEE es de 61.1%. Los pacientes con SEE presentaron en mayor proporción falla hemodinámica, renal y hematológica, sin alcanzar significancia estadística. En la fases combinadas 2 y 3 de SEE, sí se observó mayor proporción de falla renal: 88 versus 63.3%, RR = 1.8 (IC 95% 1.1-2.6, p = 0.037), así como altas dosis de vasopresores (norepinefrina > 0.1 µg/kg/min) RR = 2.3 (IC 95% 1.063-5.18, p = 0.024) y menor supervivencia, con una mediana en días de 28 (RIQ 19-39) versus 26 (RIQ 13-36), p = 0.7; PCT igual o mayor a 6 en un 65.5 versus 40%, RR = 1.87 (IC 95% 1.1-3.1, p = 0.18), mayor puntaje de SOFA con mediana de 12 (RIQ 8-4) versus 9 (RIQ 7-13) puntos, p = 0.09. Además, peores desenlaces durante la estancia hospitalaria, evaluados por un índice compuesto que incluye mortalidad, necesidad de ventilación mecánica invasiva (VMI), SOFA ≥ 9 con un RR = 1.713 (IC 95% 1.036-2.83, p = 0.05). El análisis de curva ROC detectó el mejor punto de corte de SOFA como predictor de SEE ≥ 11 con sensibilidad 60.0, especificidad 62 LR + 1.6, LR - 0.63, AUC = 0.6. RR = 1.7 (IC 95% 1.024-3.05, p = 0.034). Conclusiones: Los pacientes con SEE presentan mayor elevación de marcadores de inflamación, requerimiento de vasopresores y soporte ventilatorio, compromiso multiorgánico y mortalidad.

Abstract: Introduction: The prevalence of euthyroid sick syndrome in patients with sepsis is approximately 60%; there is little information on its correlation with multiorgan failure. Objective: To estimate the prevalence of euthyroid sick syndrome (ESS) and correlate it with the presence of specific organ failures, severity scores and clinical outcomes. Methods: Patients with diagnosis of sepsis in a critical care unit during the period from March 2014 to February 2016; we registered the clinical variables and laboratory studies, including thyroid function, in all patients. Statistical analysis: Descriptive statistics with frequency measures of central tendency and dispersion. Mortality-survival analysis with Cox regression models and Kaplan-Meier were made, as well as risk ratios and confidence intervals of 95%. A two-tailed adjusted alpha error of less than 5% was considered significant. The statistical package STATA SE version 11.1 was used. Results: Ninety patients were included, 51.1% female, aged 71 ± 14.15 years; the BMI at admission to the ICU was 24.94 ± 5.07 kg/m2. The overall prevalence of ESS was 61.1%. ESS patients presented in greater proportion with hemodynamic, renal and hematologic failure, without reaching statistical significance. In the combined phases 2 and 3 of SEE, a higher proportion of renal failure was observed: 88 vs. 63.3 %, RR = 1.8 (95% CI 1.1-2.6, p = 0.037). High doses of vasopressors (norepinephrine > 0.1 µg/kg/min) RR = 2.3 (95% CI 1.063-5.18, p = 0.024). Lower survival with a median of 28 days (IQR 19-39) versus 26 (IQR 13-36), p = 0.7. PCT greater than or equal to 6 in 65.5 versus 40%, RR = 1.87 (95% CI 1.1-3.1, p = 0.18); higher SOFA score with a median of 12 (IQR 8-4) versus 9 (IQR 7-13) points, p = 0.09. In addition to worse outcomes during hospital stay evaluated by a composite index that included mortality, need for invasive mechanical ventilation (IMV), SOFA ≥ 9 with a RR = 1.713 (95% CI 1.036-2.83, p = 0.05). ROC curve analysis detected the best cut of SOFA as a predictor of ESS ≥11, sensitivity 60.0, specificity 62 LR + 1.6, LR-0.63, AUC = 0.6. RR = 1.7 (95% CI 1.024-3.05, p = 0.034). Conclusions: Patients with ESS have higher markers of inflammation, increased requirement for vasopressors and ventilatory support, as well as elevated multiorgan failure and mortality.

Conclusões: Os pacientes com ESS apresentam maior elevação dos marcadores inflamatórios, maior necessidade de vasopressores, suporte ventilatório, compromisso múltiplo de órgãos e mortalidade.

Atypical Presentation of Multiorgan Failure Leptospirosis (Weil’s Disease) without Fever.

Leptospirosis is a zoonotic disease of sporadic occurrence caused by bacteria that belongs to the genus Leptospira. Here we report a case of rare form of leptospirosis with multiorgan failure called Weil’s disease. This patient did not have a fever which is the most common presentation of leptospirosis.

A Case of Acute Fulminant Myocarditis Progressed into and Recovered from Congestive Heart Failure and Multiorgan Failure

Myocarditis is defined as the myocardial inflammation caused by various infectious agents (such as virus, rickettsia , bacteria, protozoa, fungus and parasites). The clinical manifestations of myocarditis ranges from the asymptomatic state due to focal inflammation to fulminant fatal congestive heart failure secondary to diffuse myocardial involvement. Clinically, in some cases, it may simulate an acute myocardial infarction. We experienced a case of acute fulminant myocarditis that presented as acute myocardial infarction initially, and then progressed into and recovered from congestive heart failure and multiorgan failure.

Two Childhood Cases of Heat Stroke with Rhabdomyolysis and Multiorgan Failure

Heat stroke occurs when body thermal regulation is upset and unable to dissipate adequate amounts of heat with rise in body temperature. Thus heat stroke may result in rhabdomyolysis and multiorgan failure. We observed two childhood cases of heat stroke with rhabdomyolysis and multiorgan failure. One case was caused by accidentally being left in a car trunk for 3 hours on a sunny afternoon in late spring and the other case occurred climbing a mountain on a hot summer day during a school trip for improving individual self-control. The first case, a boy almost 5 years old, displayed thetypical clinical features of heat stroke including hyperpyrexia, CNS disturbance, hot dry skin, acute liver failure, rhabdomyolysis, oligo- anuric acute renal failure, and disseminated intravascular coagulopathy. He was treated with general supportive care and daily hemodialysis. Despite the aggressive management, he died of shock on the sixteenth day of admission day. The second case, a 14-year-old middle school boy, displayed similiar features of the first case but showed milder symptoms. He was also treated with general supportive care and daily hemodialysis for 10 days. He recovered completely and was discharged in good condition. The public including medical and paramedical personnels should be warned of the dangers of childhood heat stroke, which is potentially lethal, but preventable.
