Twenty-five patients (seven male, 18 female) were diagnosed as having the loin pain and haematuria syndrome. Presenting symptoms were either loin pain alone or pain associated with macroscopic or microscopic haematuria, and were longstanding, having been present for mean of 9.3 years in males, and 10 years in females. Ten patients described symptoms of passing gravel or renal stones but these were only demonstrated radiologically in two patients. Investigation of all patients showed anatomically normal renal tracts, normal renal function, and no significant proteinuria. Phase-contrast microscopy during episodes of haematuria revealed dysmorphic red cells in all 10 patients studied. Renal biopsies were performed in 20 patients and showed no glomerular pathology, but arteriolar and arterial hyalinosis was seen in 13 of 20 (65 per cent), fibro-elastosis in larger vessels in eight of 20 (40 per cent) and red blood cells in tubules in 13 of 20 (65 per cent) patients. The histological appearance in vessels was similar to that seen in cyclosporin A nephrotoxicity and would be consistent with the hypothesis that regional vasospasm occurs in the cortical circulation. Haematological studies in 22 patients, when compared with age and sex matched controls, showed the presence of circulating platelet aggregates, elevation of plasma beta-thromboglobulin (p less than 0.001), and increased platelet aggregation in response to serotonin and ADP (p less than 0.05 and p less than 0.03, respectively). Plasma concentrations of D dimer (p less than 0.02) and C-reactive protein (p less than 0.03) were also significantly elevated in the patient group. There was no deterioration of renal function during a mean observation period of 3.7 years and no patients developed proteinuria. Treatment was largely supportive; seven patients with intractable loin pain underwent surgical denervation with the relief of pain in four.

The 99mTc-DMSA scan is accepted as the most sensitive imaging modality for detecting areas of renal parenchymal scarring. More recently the DMSA scan has also been shown to be of value in imaging areas of renal parenchymal involvement in both children and adults with acute pyelonephritis. We assessed the acute DMSA scan findings in a consecutive series of 81 patients hospitalized with acute pyelonephritis. Acute pyelonephritis was diagnosed if the patient had a fever of > 37.8 degrees C, loin pain or tenderness and infected urine (99% Escherichia coli). Patients had a blood culture taken (8 positive), as well as a hematological (leukocytosis 75%) and biochemical screen, C-reactive protein (CRP) (increased in 57 of 66 [86%]) and urinary tract ultrasonography. If the initial DMSA scan was abnormal it was repeated after three months and in some instances again at six months. If persisting defects were noted an intravenous urogram was then undertaken. Of the 81 patients, 37 (46%) had an abnormality on the DMSA scan. Nineteen had a single defect, 12 multifocal defects, five features suggestive of pre-existing renal parenchymal scarring (all later shown to have reflux nephropathy) and one a shrunken kidney. Those patients with an abnormal scan had a higher CRP concentration than those with a normal scan. Of the 31 patients who had either a focal or multifocal defect on their initial DMSA scan there was adequate follow-up on 24 patients. In 18 of these the defects had resolved by six months (usually within three months), while of the remainder, three were shown to have reflux nephropathy, one had a large single renal cyst and another an area of parenchymal calcification. Fifty-three of 76 patients (70%) had normal ultrasonography. In adults with acute pyelonephritis, the DMSA scan may prove to be the most useful renal imaging procedure.

In the present retrospective study, we described a series of 45 non-icteric leptospirosis and 44 nephropathia epidemica (NE) patients diagnosed in the northeast of France from 1995 to 2005 and compared their clinical picture and laboratory parameters, as well as some epidemiological data. Loin pain (P < 0.001), abdominal pains (P = 0.007), rise of blood pressure (P < 0.001) and pharyngitis (P = 0.01) were more frequently found in NE patients. Aspartate aminotransferase (ASAT) (P = 0,006), creatine phosphokinase (CPK) (P < 0.0001) and C-reactive protein (CRP) (P < 0.0001) were higher in leptospirosis, whereas creatinine (P = 0.009) was higher in NE. Leptospirosis mainly concerns occupational hazards, e.g. farmers, and leisure activities like swimming, and NE concerns professional foresters or leisure activities in the forest and the cleaning of attics. During hospitalisation, patients receiving antibiotics were more frequent among leptospirosis than among NE patients (80% versus 59%, P = 0.06). Among the various common clinical signs, only acute myopia appeared to be a pathognomonic but inconsistently observed clinical sign, which was only observed in 47% of NE cases.

Renal infarction is relatively a rare condition that is often linked to the presence of underlying cardiac disease such as atrial fi brillation and valvular heart disease. While the classic presentation of renal infarction includes persistent abdominal or loin pain with high serum levels of lactate dehydrogenase (LDH), microscopic hematuria and high C-reactive protein (CRP), patients can present without these features. It is important to have high index of suspicion for this condition in patients who present with unexplained back or abdominal pain, even if there are no known traditional risk factors. Herein, we describe the case of a 42-year-old man who presented with abdominal pain and found to have acute right and subacute bilateral renal infarcts. No cause was identifi ed despite exhaustive work up. Interestingly, his urinalysis, LDH and CRP were within normal limits.
