Macrohaematuria and microhematuria may be signs of various diseases. Infectious haematuria often presents with fever and/or dysuria. The paper describes the case of a 14-year-old boy from Mali who was in Italy for five months and presented with gross haematuria and dysuria for three weeks. He was afebrile and denied abdominal symptoms. The physical examination was normal. The blood count showed absolute hypereosinophilia and mild microcytic anaemia. The analysis of the urine showed proteinuria and haemoglobinuria, while the urine culture was negative. Ultrasound of the urinary tract revealed a periurethral microcyst. The search for Plasmodium falci- parum (PH) was positive (parasitaemia < 0.1%). Given the haematuria and hypereosinophilia, serological tests were carried out for intestinal parasites and revealed an- ti-schistosome IgG antibodies positivity.

La macroematuria e la microematuria possono essere segni di diverse patologie. Le ematurie infettive spesso si presentano con febbre e disuria. Si riporta il caso di un ragazzo di 14 anni, originario del Mali e in Italia da cin- que mesi, che ha sviluppato macroematuria e disuria per- sistenti per tre settimane, senza febbre. L’esame obiettivo era nella norma, l’emocromo mostrava ipereosinofilia e lieve anemia microcitica. L'analisi delle urine evidenziava proteinuria ed emoglobinuria, mentre l’urinocoltura risul- tava negativa. L’ecografia delle vie urinarie rivelava una microcisti periuretrale. La ricerca di Plasmodium falcipa- rum (PH) risultava positiva con parassitemia < 0,1%. Considerando l’ematuria e l’ipereosinofilia, sono stati eseguiti accertamenti sierologici per parassiti intestinali, rivelando IgG anti-schistosoma positive. L’analisi delle urine ha poi confermato la presenza di uova di Schistoso- ma haematobium (SH). Il paziente è stato quindi trattato con diidroartemisinina-piperachina e praziquantel. Questo caso evidenzia come l’aumento dei flussi migratori e il cambiamento climatico possano ampliare la diffusione di malattie tropicali in Italia, sottolineando l’importanza di un processo diagnostico integrato che consideri anamnesi e fattori epidemiologici.

Abstract
Macrohaematuria and microhematuria may be signs of various diseases. Infectious haematuria often presents with fever and/or dysuria. The paper describes the case of a 14-year-old boy from Mali who was in Italy for five months and presented with gross haematuria and dysuria for three weeks. He was afebrile and denied abdominal symptoms. The physical examination was normal. The blood count showed absolute hypereosinophilia and mild microcytic anaemia. The analysis of the urine showed proteinuria and haemoglobinuria, while the urine culture was negative. Ultrasound of the urinary tract revealed a periurethral microcyst. The search for Plasmodium falci- parum (PH) was positive (parasitaemia < 0.1%). Given the haematuria and hypereosinophilia, serological tests were carried out for intestinal parasites and revealed an- ti-schistosome IgG antibodies positivity. Microscopic analysis of the urinary sediment highlighted the presence of SH eggs. Dihydroartemisinine-piperaquine and pra- ziquantel were administered. Recent migratory flows and climate change have increased the spread of tropical dis- eases in Italy. A diagnostic process that integrates anam- nesis and epidemiological notions is essential.| File | Dimensione | Formato | |
