Severe pertussis complicated by pulmonary hypertension in a Moroccan infant: a case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDespite high vaccination coverage among children, pertussis continues to pose a significant public health challenge in Morocco. Mortality primarily affects infants under 1 year of age. Although cases of mortality caused by pulmonary hypertension induced by Bordetella pertussis infection have been recorded previously, this complication continues to be relatively uncommon. The main aim of this case report is to raise awareness of this rare but serious complication of pertussis to promote early diagnosis and ensure timely and appropriate therapeutic interventions to improve prognosis. CASE PRESENTATION: A 2-month-old Moroccan girl presented with respiratory distress characterized by paroxysmal, emetic, and cyanotic coughing, followed by noisy inspiratory catch-up. Initial examination revealed a temperature of 38.3 °C, blood pressure of 88/67 mmHg, tachycardia (220 bpm), and tachypnea (70 cpm), with oxygen saturation of 86%. Pulmonary auscultation detected diffuse bilateral rhonchi. Laboratory findings showed leukocytosis (114,000/µL) with neutrophil predominance. Polymerase chain reaction confirmed Bordetella pertussis infection. A thoracic computed tomography scan revealed alveolo-interstitial pneumonia and atelectasis of the middle lobe. Echocardiography indicated pulmonary hypertension (V
conclusionThis case report aims to inform practitioners of the rare association between pertussis and pulmonary hypertension. Early diagnosis and aggressive management can improve outcomes and prognosis. This case is a reminder of the complex pathophysiology and therapeutic challenges associated with severe pertussis, underlining the importance of a multidisciplinary approach to optimize the diagnostic and therapeutic management of such patients.
