From Bronchodilation to Lactic Acidosis: A Case Report on Salbutamol's Adverse Effect.

Asthma is one of the most prevalent chronic respiratory diseases, characterized by bronchial hyper-responsiveness and intermittent airflow obstruction. Short-acting ß2 agonists (SABA) remain the cornerstone of acute asthma management due to its properties in smooth muscle relaxation and bronchodilatation. Rarely, these drugs might be associated with adverse effects, including the development of metabolic and hydro-electrolytic imbalances. We report a case of lactic acidosis secondary to ß2 agonists in a young female patient admitted with severe acute asthma. After initial management and significant improvement of the respiratory distress with nebulized and subcutaneous salbutamol, the patient developed high anion gap metabolic acidosis due to hyperlactacidemia and hypokalemia. Alternative causes of lactic acidosis were discarded, such as severe hypoxemia, systemic hypoperfusion, sepsis, and organ dysfunction, and SABA-related lactic acidosis was suspected. This treatment was halted, and tachypnea, metabolic acidosis, and lactate levels rapidly resolved. The remainder of the hospital stay was uneventful, and the patient was discharged after a period of five days. Although rare, the development of unexplained lactic acidosis in a SABA-treated patient should alert the treating physician to this ß2 agonist side-effect.

Strongyloides stercoralis Dissemination and Hyperinfection Associated with Long-Term Steroid Treatment in a Neurosurgical Population.

Strongyloidiasis develops from the infection with Strongyloides stercoralis (Family: Strongylidae) and was recently considered a neglected tropical disease by the World Health Organization due to its global distribution and high burden of infection. Here, we present the cases of two patients under corticosteroid therapy after neurosurgical surgery who developed septic shock-like hyperinfection syndrome due to disseminated strongyloidiasis. The first case is a 77-year-old man from Cape Verde who was diagnosed with an extra-axial right parietal brain mass. He was given dexamethasone and was submitted to a biparietal craniotomy. His condition deteriorated and he was admitted to the intensive care unit (ICU), where he was diagnosed with disseminated strongyloidiasis with hyperinfection. Anthelmintic treatment and corticosteroid therapy were rapidly tapered and stopped. Neurological dysfunction persisted and the patient was transferred to the ward. The patient had died after complications of hospital-acquired pneumonia. The second case is a 47-year-old man from Guinea-Bissau who was diagnosed with a space-occupying lesion in the right temporal region and started treatment with dexamethasone. He underwent a craniectomy with partial excision of the lesion (high-grade glioma). Later his neurologic state worsened, and he was diagnosed with septic shock and hospital-acquired pneumonia. He was admitted to the ICU, the diagnosis of disseminated strongyloidiasis and hyperinfection syndrome was made and he initiated treatment with ivermectin and albendazole. Corticosteroid therapy was tapered. The patient's clinical status deteriorated, and multiple opportunistic infections were diagnosed during the ICU stay, which lead him to die. Clinicians should have a high index of suspicion when in the presence of corticosteroid-treated patients with sepsis. Preventive strategies and subsequent treatment should be considered in patients with a risk of acquisition or dissemination. Treating severe strongyloidiasis is still a clinical challenge and a delayed diagnosis can significantly worsen the outcomes of the patients affected, as seen in the presented cases.

Tuberculosis and Its "Troubled Relationship" With Other Diseases.

Tuberculosis (TB) is a multisystemic disease caused most frequently by Mycobacterium tuberculosis. Extrapulmonary TB has become more frequent with the advent of human immunodeficiency virus (HIV) as HIV can facilitate the infection with M. tuberculosis, especially during HIV seroconversion. Here, we present the case of a 22-year-old man, from Guinea-Bissau, with a history of untreated HIV who was admitted to the intensive care unit for respiratory failure needing mechanical ventilation. Pulmonary TB was diagnosed. His stay was complicated with a hemorrhagic shock due to traumatic urethral catheterization, which led to a perforation of the capsule of the prostate. A prostatectomy was needed for bleeding control. The anatomopathological examination confirmed the presence of acid-resistant bacilli, and an extensive caseous type necrosis of the whole tissue, thus diagnosing a prostatic tuberculosis. The patient recovered after a hemorrhagic shock, a urologic and radical intervention, and some severe infectious complications.
