   Abstract 

Piperazine as an antihelminth has many adverse effects, especially on patients with renal insufficiency. We report the use of piperazine in a girl with a moderately severe kidney disease due to Biedl Bardet syndrome. She developed coma and acute kidney injury due to acute interstitial nephritis (AIN), anemia and thrombocytopenia. The presence of fever, proteinuria, acidosis, anemia, sterile pyuria and non-oliguric renal failure strongly suggested AIN. Her problems abated mostly by discontinuing of piperazine and supportive therapy, except anemia and thrombocytopenia.

   Introduction Top


Piperazine has been used to treat pinworm and roundworm infections for over 40 years. How­ever, it may induce cerebellar ataxia, dropping of objects, clumsiness and gait abnormalities in the setting of overdose or renal insufficiency. [1] In pediatric patients, the usual oral dose ranges from 65 to 75 mg/kg/day (max: 3.5 g/day as a single dose). Piperazin in less than 1% of patients may be associated with adverse reac­tions, including cause bronchospasm, diarrhea, dizziness, EEG changes, headache, hemolytic anemia, hypersensitivity reactions, nausea, sei­zure, vertigo, visual impairment, vomiting and generalized weakness. [2]

Biedl Bardet syndrome (BBS) is an autosomal recessive disorder that presents as obesity, polydactyli, mental retardation, retinal dystrophy, hypogonadism and renal abnormalities due to cystic dysplasia. [3]

In this report, we describe a BBS patient who used piperazine for two days. The patient deve­loped, afterwards, neurological, renal and hema­tological side-effects.


   Case Report Top


An 8-year-old girl diagnosed as BBS because of polydactyli (six toes in her feet), obesity (body mass index: 30, which is above the 97% percentile for her age), mental retardation and renal insufficiency [Figure 1] and [Figure 2]. She pre­sented to the emergency room in coma that developed in the morning after waking up and progressed during day. She received piperazin hydrate for two days in a total dose of 150 mg/ kg (75 mg/kg/d × 2).

Initially, her laboratory findings revealed blood urea nitrogen (BUN) of 90 mmol/L and crea­tinine 3.9 mg/dL. She was mildly anemic and acidotic [Table 1]. Her clinical condition wor­sened on the third day and her temperature fluctuated between 37.9 and 40°C, but without oliguria or dehydration. She suffered from res­piratory distress. Her blood pressure was nor­mal. On physical examination, her Glasgow coma scale (GCS) was 7 and she had involun­tary jerking movements in her legs, arms and trunks accentuated by sensory triggers.

The patient's chest radiograph was normal, but her blood BUN and creatinine increased and urinalysis revealed sterile pyuria besides nega­tive blood/urine culture, and all suggested acute interstitial nephritis (AIN).

In renal ultrasound, the patient had severely atrophic bilateral kidneys (long axis: 55 mm) and increased echogenicity with undifferen­tiated corticomedullay boundaries, but without evidence for ascites or volume overload.

We started Methylprednisolone pulse 10 mg/kg for two days, followed by prednisone 1 mg/kg/ daily for two weeks. Her clinical and laboratory conditions resolved dramatically [Table 1]. She had a significant proteinuria at first (urine pro­tein/urine creatinine: 3 mg/g normal <0.5); after one month of therapy for AIN, it decreased to normal.

During the first three days she was febrile and, in spite of her body fluids being sterile, there was no leukocytosis or serum-reactive proteins like C-reactive protein in her serum. After three days of supportive therapy, she opened her eyes for a moment and then her alertness recovered, but she could not sit or stand as she had intentional tremor and slurred speech. After one week, she could sit and then walked with help, while after two weeks she left the hospital in a good condition.


   Discussion Top


BBS is characterized by obesity, polydactyli, mental retardation, retinal dystrophy, hypogo­nadism and some grades of renal abnormalities, typically cystic renal dysplasia. [3] Our case had similar signs and symptoms including obesity, polydactyli, mental retardation, retinal degene­ration, nystagmus and chronic kidney disease presenting Piperazine, an antihelminthic drug, used widely for the treatment of ascaris and thread-worm infestations. Brown et al [4] described neurotoxic symptoms following piperazin as transient neurological disturbance, characte­rized by vertigo, tremor, incoordination, visual and memory disturbances, sense of detachment and muscular weakness due to overdosage and retention of piperazine in the patients with poor renal function. [5] Other adverse effects were reported for piperazine in normal people such as hypersensitivity and urticaria in a child who developed hemolytic anemia after two days of use of piperazine, [6] severe thrombocytopenia that developed in a 61-year-old man due to sensitization, [7] a reaction resembling viral hepa­titis that occurred in a 25-year-old woman [8] and serum sickness in another patient. [9] Our patient was categorized as stage 4 of chronic kidney disease (CKD) with a measured GFR of 25 mL/min/1.73 m 2 . She received piperazine of 75 mg/kg/d for two days, her signs and symptoms appeared on the third day and were compatible with AIN. She also revealed hypochromic mic­rocytic anemia, mild thrombocytopenia, mode­rate acidosis, respiratory distress, deep coma, mycolonic jerks, hypersensitivity to sensory sti­mulation, tremor, incoordination, scanned speech, delusion and muscle weakness. Her acidosis appeared and resolved sooner and her fever abated in one week and proteinuria after one month, but her anemia and thrombocytopenia persisted and mild eosinophilia appeared (600 cells/mm 3 ) in the second week.

Piperazine in a total dose 150 mg/kg after two days caused encephalopathy, respiratory dis­tress, metabolic acidosis and acute kidney injury (AKI) imposed on CKD. All the side-effects were transient, but the hematological ad­verse effects (anemia, non-hemolytic thrombo­cytopenia and eosinophilia) persisted.
